                             ABOUT THIS PROSPECTUS

   This prospectus is part of a "shelf" registration statement that Alcoa and
the Alcoa Trust have filed with the SEC. By using a shelf registration
statement, we may sell, from time to time, in one or more offerings, any
combination of the securities described in this prospectus in a dollar amount
that does not exceed $3,000,000,000. For further information about Alcoa's
business, the Alcoa Trust and the securities, you should refer to the
registration statement and its exhibits. The exhibits to our registration
statement contain the full text of certain contracts and other important
documents we have summarized in this prospectus. Since these summaries may not
contain all the information that you may find important in deciding whether to
purchase the securities we may offer, you should review the full text of these
documents. The registration statement can be obtained from the SEC as indicated
under the heading "Where You Can Find More Information."

   This prospectus only provides you with a general description of the
securities we may offer. Each time we sell securities, we will provide a
prospectus supplement that contains specific information about the terms of
those securities. The prospectus supplement may also add, update or change
information contained in this prospectus. You should read both this prospectus
and any prospectus supplement together with the additional information
described below under the heading "Where You Can Find More Information."

   You should rely only on the information contained or incorporated by
reference in this prospectus and the prospectus supplement. We have not
authorized anyone to provide you with different information. If anyone provides
you with different or inconsistent information, you should not rely on it. We
will not make an offer to sell these securities in any jurisdiction where the
offer or sale is not permitted. You should assume that the information
appearing in this prospectus, as well as information we previously filed with
the SEC and incorporated by reference in this prospectus, is accurate only as
of the date on the front cover of this prospectus. Our business, financial
condition, results of operations and prospects may have changed since that
date.

                      WHERE YOU CAN FIND MORE INFORMATION

                                 ALCOA TRUST I

   The Alcoa Trust is a statutory business trust formed under Delaware law
pursuant to:

  .  a Declaration of Trust (a "Declaration") executed by Alcoa, as sponsor
     for the Alcoa Trust, and the trustees of the Alcoa Trust; and

  .  the filing of a certificate of trust with the Delaware Secretary of
     State.

   Unless an accompanying prospectus supplement provides otherwise, the Alcoa
Trust exists for the sole purposes of:

  .  selling trust preferred securities and investing the proceeds in a
     specific series of subordinated debt securities issued by Alcoa;

  .  issuing and selling common securities to Alcoa in exchange for cash and
     investing the proceeds in additional subordinated debt securities issued
     by Alcoa; and

  .  engaging in other activities that are necessary, convenient or
     incidental to the sale of trust preferred and common securities or the
     purchase of Alcoa debt securities.

   The Alcoa Trust will not borrow money, issue debt or reinvest proceeds
derived from investments, pledge any of its assets, or otherwise undertake, or
permit to be undertaken, any activity that would cause the Alcoa Trust not to
be classified for United States Federal income tax purposes as a grantor trust.
Alcoa will own all of the trust common securities issued by the Alcoa Trust.
The trust common securities will rank pari passu, and payments will be made
thereon pro rata, with the trust preferred securities, except that upon the
occurrence and continuance of an event of default under the Declaration, the
rights of the holders of the trust common securities to payment in respect of
distributions and payments upon liquidation, redemption and otherwise will be
subordinated to the rights of the holders of the trust preferred securities. In
connection with the issuance of trust preferred securities by the Alcoa Trust,
Alcoa will acquire trust common securities having an aggregate liquidation
amount equal to a minimum of 3% of the total capital of the Alcoa Trust. The
Alcoa Trust will have a term of 40 years, but may terminate earlier as provided
in the Declaration.

   The Alcoa Trust's business and affairs will be conducted by the trustees.
The holder of the trust common securities will be entitled to appoint, remove
or replace any of, or increase or reduce the number of, the trustees of the
Alcoa Trust. The duties and obligations of the trustees will be governed by the
Declaration of the Alcoa Trust. At least one of the trustees of the Alcoa Trust
will be a person who is an employee or officer of or who is affiliated with
Alcoa (a "Regular Trustee"). One trustee of the Alcoa Trust will be a financial
institution that is not affiliated with Alcoa, which will act as property
trustee and as indenture trustee for the purposes of the Trust Indenture Act of
1939, as amended (the "Trust Indenture Act"), pursuant to the terms set forth
in the applicable prospectus supplement (the "Property Trustee"). In addition,
unless the Property Trustee maintains a principal place of business in the
State of Delaware and otherwise meets the requirements of applicable law, one
trustee of the Alcoa Trust will be a legal entity having a principal place of
business in, or an individual resident of, the State of Delaware (the "Delaware
Trustee").

   Alcoa will pay all fees and expenses related to the Alcoa Trust and the
offering of the trust preferred securities. Unless otherwise set forth in the
prospectus supplement, the Property Trustee will be The Chase Manhattan Bank,
and the Delaware Trustee will be Chase Manhattan Bank Delaware. The office of
the Delaware Trustee in the State of Delaware is 1201 Market Street,
Wilmington, Delaware 19801. The principal place of business of the Alcoa Trust
is c/o Alcoa Inc., 201 Isabella Street, Pittsburgh, Pennsylvania 15212-5858
(telephone: (412) 553-4545).

                      RATIOS OF EARNINGS TO FIXED CHARGES

   The following table sets forth the ratio of Alcoa's earnings to fixed
charges for the periods indicated:

<TABLE>
<CAPTION>
                              Year Ended December 31,

</TABLE>

   The ratios include all earnings, before extraordinary items and the
cumulative effects of accounting changes, and fixed charges of Alcoa and its
majority owned subsidiaries. Earnings have been calculated by adding to net
income the provision for taxes on income, amortization of capitalized interest,
interest expense and an amount representative of the interest factor in
rentals, the distributed income of less than 50% owned entities, and have been
decreased by the undistributed earnings of entities less than 50% owned,
preferred stock dividend requirements of majority owned subsidiaries and the
minority interest share in the losses of majority owned subsidiaries without
fixed charges of Alcoa. Fixed charges consist of total interest expense,
amortization of debt expense, an amount representative of the interest factor
in rentals, capitalized interest and preferred stock dividend requirements of
majority owned subsidiaries.

                                USE OF PROCEEDS

   Unless otherwise specified in a prospectus supplement, Alcoa will use the
net proceeds from the sale of the securities offered by it for general
corporate purposes, including repayment of borrowings (including borrowings
under Alcoa's commercial paper program), working capital, capital expenditures,
stock repurchase programs and acquisitions. Unless otherwise specified in a
prospectus supplement, the Alcoa Trust will use the net proceeds from the sale
of the trust preferred securities to purchase subordinated debt securities of
Alcoa.

     securities will be issuable, if other than the denomination of $5,000;

     set forth in the indenture in which any such book-entry security may be
     transferred to, and registered and exchanged for senior debt securities
     registered in the name of, a person other than the depository for such
     book-entry security or a nominee thereof and in which any such transfer
     may be registered;

  .  any other terms of the senior debt securities not inconsistent with the
     provisions of the indenture (Section 301); and

  .  any special provisions for the payment of additional amounts with
     respect to the senior debt securities.

   Senior debt securities may be issued at a substantial discount below their
stated principal amount. Certain United States Federal income tax
considerations applicable to senior debt securities issued at a discount and to
senior debt securities that are denominated in a currency other than United
States dollars will be described in the applicable prospectus supplement.

   Senior debt securities may also be issued under the indenture upon the
exercise of warrants issued by Alcoa. See "Description of Warrants." United
States Federal income tax consequences applicable to any warrants will be set
forth in the applicable prospectus supplement.

Form, Exchange, Registration and Transfer

   Senior debt securities may be issued in registered form or bearer form or
both, as specified in the terms of the series. Unless otherwise indicated in an
applicable prospectus supplement, definitive bearer securities will

                                       9
<PAGE>

have interest coupons attached. (Section 201) Senior debt securities of a
series may also be issuable in temporary and permanent global form. (Section
201) See "Permanent Global Securities."

   In connection with its sale during the restricted period (as defined in
United States Treasury Regulations Section 1.163-5(c)(2)(i)(D)(7)), no bearer
security, including a senior debt security in permanent global form, may be
mailed or otherwise delivered to any location in the United States or its
possessions. No bearer security other than a temporary global bearer security
may be delivered, nor may interest be paid on any bearer security unless the
person entitled to receive the bearer security or interest furnishes written
certification, in the form required by the indenture, to the effect that such
person:

  .  is not a United States person;

  .  is a foreign branch of a United States financial institution purchasing
     for its own account or for resale, or is a United States person who
     acquired the senior debt security through such a financial institution
     and who holds the senior debt security through such financial
     institution on the date of certification. In either of such cases, such
     financial institution must provide a certificate to Alcoa or the
     distributor selling the senior debt security to it stating that it
     agrees to comply with the requirements of Section 165(j)(3)(A), (B) or
     (C) of the Internal Revenue Code of 1986, as amended, and the United
     States Treasury Regulations thereunder; or

  .  is a financial institution holding for purposes of resale during the
     restricted period (as defined in United States Treasury Regulations
     Section 1.163-5(c)(2)(i)(D)(7)).

   A financial institution holding for purposes of resale during the restricted
period, whether or not also satisfying the other two prongs of the above
sentence, must certify that it has not acquired the senior debt security for
purposes of resale directly or indirectly to a United States person or to a
person within the United States or its possessions. In the case of a bearer
security in permanent global form, such certification must be given in
connection with notation of a beneficial owner's interest therein. (Section
303) See "Temporary Global Securities."

   Senior debt securities may be presented for exchange as follows:

  .  Registered securities will be exchangeable for other registered
     securities of the same series.

  .  If senior debt securities have been issued as both registered securities
     and bearer securities, subject to certain conditions, holders may
     exchange bearer securities for registered securities of the same series
     of any authorized denominations and of a like aggregate principal amount
     and tenor.

  .  Bearer securities surrendered in exchange for registered securities
     between a regular record date or a special record date and the relevant
     date for payment of interest must be surrendered without the coupon
     relating to such date for payment of interest and interest will not be
     payable in respect of the registered security issued in exchange for
     such bearer security, but will be payable only to the holder of such
     coupon when due in accordance with the terms of the indenture.

  .  Bearer securities will not be issued in exchange for registered
     securities.

  .  Each bearer security other than a temporary global bearer security will
     bear a legend substantially to the following effect: "Any United States
     Person who holds this obligation will be subject to limitations under
     the United States income tax laws, including the limitations provided in
     Sections 165(j) and 1287(a) of the Internal Revenue Code."

   Registered securities may be presented for registration of transfer, with
the form of transfer endorsed thereon duly executed, if so required by Alcoa or
the trustee or any transfer agent, at the office of the security registrar or
at the office of any transfer agent designated by Alcoa for that purpose with
respect to any series of senior debt securities and referred to in the
applicable prospectus supplement, without service charge and upon payment of
any taxes and other governmental charges as described in the indenture. Any
transfer or exchange

                                       10
<PAGE>

will be effected once the security registrar or transfer agent, as the case may
be, is satisfied with the documents of title and identity of the person making
the request. (Section 305)

   If a prospectus supplement refers to any transfer agents, in addition to the
security registrar, initially designated by Alcoa with respect to any series of
senior debt securities, Alcoa may at any time rescind the designation of any
additional transfer agent or approve a change in the location through which any
transfer agent acts. If senior debt securities of a series are issuable solely
as registered securities, Alcoa will be required to maintain a transfer agent
in each place of payment for the series. If senior debt securities of a series
are issuable as bearer securities, Alcoa will be required to maintain, in
addition to the security registrar, a transfer agent in a place of payment for
the series located outside the United States. Alcoa may at any time designate
additional transfer agents with respect to any series of senior debt
securities. (Section 1002)

   If debt securities of a series are redeemed in part, Alcoa will not be
required to:

  .  issue, register the transfer of or exchange senior debt securities of
     the series during a period beginning at the opening of business 15 days
     before any selection of senior debt securities of that series to be
     redeemed and ending at the close of business on:

    .  if senior debt securities of the series are issuable only as
       registered securities, the day of mailing of the relevant notice of
       redemption, and

    .  if senior debt securities of the series are issuable as bearer
       securities, the day of the first publication of the relevant notice
       of redemption or, if senior debt securities of the series are also
       issuable as registered securities and there is no publication, the
       mailing of the relevant notice of redemption;

  .  register the transfer of or exchange any registered security, or portion
     thereof, called for redemption, except the unredeemed portion of any
     registered security being redeemed in part; or

  .  exchange any bearer security called for redemption, except to exchange
     such bearer security for a registered security of that series and like
     tenor which is immediately surrendered for redemption. (Section 305)

Payment and Paying Agents

   Unless otherwise indicated in an applicable prospectus supplement, payment
of principal of and any premium and interest on registered securities will be
made at the office of the paying agent(s) designated by Alcoa from time to
time. At the option of Alcoa, payment of any interest may instead be made by
check mailed to the address of the person entitled thereto as such address
appears in the security register. Unless otherwise indicated in an applicable
prospectus supplement, payment of any installment of interest on registered
securities will be made to the person in whose name the registered security is
registered at the close of business on the regular record date for that
interest. (Section 307)

   Unless otherwise indicated in an applicable prospectus supplement, payment
of principal of and any premium and interest on bearer securities will be
payable, subject to any applicable laws and regulations, at the offices of
paying agents outside the United States as Alcoa may designate from time to
time by check or by transfer, at the option of the holder, to an account
maintained by the payee with a bank located outside the United States. Unless
otherwise indicated in an applicable prospectus supplement, payment of interest
on bearer securities on any interest payment date will be made only against
surrender outside the United States, to the paying agent, of the coupon
relating to that interest payment date. (Section 1001) No payment with respect
to any bearer security will be made at any office or agency of Alcoa in the
United States or by check mailed to any address in the United States or by
transfer to an account maintained with a bank located in the United States.
Notwithstanding the foregoing, payments of principal of and any premium and
interest on bearer securities denominated and payable in U.S. dollars will be
made at the office of Alcoa's paying agent in the Borough of Manhattan, the
City of New York, if, but only if, payment of the full amount thereof in U.S.
dollars

                                       11
<PAGE>

at all offices or agencies outside the United States is illegal or effectively
precluded by exchange controls or other similar restrictions. (Section 1002)

   Unless otherwise indicated in an applicable prospectus supplement, the
corporate trust office of the trustee in Pittsburgh, Pennsylvania will be
designated as a paying agent for Alcoa for payments with respect to senior debt
securities which are issuable solely as registered securities. Alcoa will
maintain a paying agent outside of the United States for payments with respect
to senior debt securities, subject to the limitations described above on bearer
securities, which are issuable solely as bearer securities, or as both
registered securities and bearer securities. Any paying agents outside the
United States and any other paying agents in the United States initially
designated by Alcoa for the senior debt securities will be named in an
applicable prospectus supplement. Alcoa may at any time designate additional
paying agents or rescind the designation of any paying agent or approve a
change in the office through which any paying agent acts. If senior debt
securities of a series are issuable solely as registered securities, Alcoa will
be required to maintain a paying agent in each place of payment for the series.
If senior debt securities of a series are issuable as bearer securities, Alcoa
will be required to maintain:

  .  a paying agent in the Borough of Manhattan, the City of New York, for
     payments with respect to any registered securities of the series and for
     payments with respect to bearer securities of the series in the
     circumstances described above, but not otherwise; and

  .  a paying agent in a place of payment located outside the United States
     where senior debt securities of the series and any coupons appertaining
     thereto may be presented and surrendered for payment. If the senior debt
     securities of such series are listed on The Stock Exchange of the United
     Kingdom and the Republic of Ireland or the Luxembourg Stock Exchange or
     any other stock exchange located outside the United States and such
     stock exchange so requires, Alcoa will maintain a paying agent in London
     or Luxembourg or any other required city located outside the United
     States, as the case may be, for the senior debt securities of such
     series. (Section 1002)

   All moneys paid by Alcoa to a paying agent for the payment of principal of
and any premium or interest on any senior debt security which remain unclaimed
at the end of two years after such principal, premium or interest becomes due
and payable will be repaid to Alcoa. Thereafter, the holder of any such senior
debt security or any coupon may look only to Alcoa for payment. (Section 1003)

Book-Entry Securities

   The senior debt securities of a series may be issued in the form of one or
more registered securities that will be registered in the name of a depository
or its nominee and bear a legend as specified in the indenture. These senior
debt securities will be known as book-entry securities. Unless otherwise
indicated in the applicable prospectus supplement, a book-entry security may
not be registered for transfer or exchange to any person other than the
depository or its nominee unless:

  .  the depository notifies Alcoa that it is unwilling to continue as
     depository or ceases to be a clearing agency registered under the
     Exchange Act;

  .  Alcoa executes and delivers to the trustee a company order that the
     transfer or exchange of the book-entry security will be registrable; or

  .  there has occurred and is continuing an event of default, or an event
     that after notice or lapse of time, or both, would be an event of
     default, with respect to the senior debt securities evidenced by the
     book-entry security.

Upon the occurrence of any of the conditions specified above or other
conditions as may be specified as contemplated by the indenture, the book-entry
security may be exchanged for senior debt securities of the series registered
in the names of, and the transfer of the book-entry security may be registered
to, such persons, including persons other than the depository with respect to
such series and its nominees, as the depository may direct.

                                       12
<PAGE>

   The specific terms of the depositary arrangement with respect to any portion
of a series of registered book-entry securities to be represented by a book-
entry security will be described in the applicable prospectus supplement. Alcoa
expects that the following provisions will apply to depositary arrangements.

   Unless otherwise specified in the applicable prospectus supplement, senior
debt securities that are to be represented by a book-entry security to be
deposited with or on behalf of a depository will be represented by a book-entry
security registered in the name of the depository or its nominee. Upon the
issuance of a book-entry security, and the deposit of the book-entry security
with or on behalf of the depository, the depository will credit, on its book-
entry registration and transfer system, the respective principal amounts of the
senior debt securities represented by the book-entry security to the accounts
of institutions that have accounts with the depository or its nominee. The
accounts to be credited will be designated by the underwriters or agents of the
senior debt securities or by Alcoa if the senior debt securities are offered
and sold directly by Alcoa. Ownership of beneficial interests in a book-entry
security will be limited to the institutions that have accounts with the
depository or persons that may hold interests through the institutions.
Ownership of beneficial interests by the institutions in the book-entry
security will be shown on, and the transfer of that ownership interest will be
effected only through, records maintained by the depository or its nominee for
the book-entry security. Ownership of beneficial interests in the book-entry
security by persons that hold through the institutions will be shown on, and
the transfer of that ownership interest within the institution will be effected
only through, records maintained by that institution. The laws of some
jurisdictions require that certain purchasers of securities take physical
delivery of securities in certificated form. The foregoing limitations and such
laws may impair the ability to transfer beneficial interests in book-entry
securities.

   So long as the depository for a book-entry security, or its nominee, is the
registered owner of that book-entry security, the depository or nominee, as the
case may be, will be considered the sole owner or holder of the senior debt
securities represented by the book-entry security for all purposes under the
indenture. Unless otherwise specified in the applicable prospectus supplement,
owners of beneficial interests in a book-entry security:

  .  will not be entitled to have senior debt securities of the series
     registered in their names;

  .  will not receive or be entitled to receive physical delivery of senior
     debt securities in certificated form; and

  .  will not be considered the holders of debt securities for any purposes
     under the indenture. (Sections 204 and 305)

Accordingly, each person owning a beneficial interest in a book-entry security
must rely on the procedures of the depository and, if such person does not have
an account with the depository, on the procedures of the institution through
which such person owns its interest, to exercise any rights of a holder under
the indenture. The indenture provides that the depository may grant proxies and
otherwise authorize participants to give or take any request, demand,
authorization, direction, notice, consent, waiver or other action that a holder
is entitled to give or take under the indenture. (Section 104) Alcoa
understands that under existing industry practices, if Alcoa requests any
action of holders, or if an owner of a beneficial interest in such book-entry
security desires to give any notice or take any action a holder is entitled to
give or take under the indenture, the depository would authorize the
participants to give such notice or take such action, and participants would
authorize beneficial owners owning through such participants to give such
notice or take such action or would otherwise act upon the instructions of
beneficial owners owning through them.

Temporary Global Securities

   If so specified in an applicable prospectus supplement, all or any portion
of the senior debt securities of a series that are issuable as bearer
securities may initially be represented by one or more temporary global senior
debt securities, without interest coupons, to be deposited with a common
depositary in London for the Euroclear System ("Euroclear") and Clearstream
Luxembourg for credit to the designated accounts. On and

                                       13
<PAGE>

after the date determined as provided in any temporary global senior debt
security and described in an applicable prospectus supplement, each temporary
global senior debt security will be exchanged for an interest in a permanent
global bearer security as specified in an applicable prospectus supplement,
but, unless otherwise specified in an applicable prospectus supplement, only
upon receipt of:

  .  written certification from Euroclear or Clearstream Luxembourg, as the
     case may be, in the form and to the effect required by the indenture (a
     "Depository Tax Certification"); and

  .  written certification by Euroclear or Clearstream Luxembourg from the
     person entitled to receive such senior debt securities in the form and
     to the effect described under "Form, Exchange, Registration and
     Transfer."

No definitive bearer security, including a senior debt security in permanent
global form that is either a bearer security or exchangeable for bearer
securities, delivered in exchange for a portion of a temporary or permanent
global senior debt security may be mailed or otherwise delivered to any
location in the United States in connection with such exchange. (Section 304)

   Unless otherwise specified in an applicable prospectus supplement, interest
in respect of any portion of a temporary global senior debt security payable in
respect of an interest payment date occurring before the issuance of securities
in permanent global form will be paid to each of Euroclear and Clearstream
Luxembourg with respect to the portion of the temporary global senior debt
security held for its account following the receipt by Alcoa or its agent of a
Depository Tax Certification. Each of Euroclear and Clearstream Luxembourg will
undertake in such circumstances to credit such interest received by it in
respect of a temporary global senior debt security to the respective accounts
for which it holds such temporary global senior debt security only upon receipt
in each case of certification in the form and to the effect described under
"Form, Exchange, Registration and Transfer" with respect to the portion of such
temporary global senior debt security on which such interest is to be so
credited. Receipt of the certification described in the preceding sentence by
Euroclear or Clearstream Luxembourg, as the case may be, will constitute
irrevocable instructions to Euroclear or Clearstream Luxembourg to exchange
such portion of the temporary global senior debt security with respect to which
such certification was received for an interest in a permanent global senior
debt security.

Permanent Global Securities

   If any senior debt securities of a series are issuable in permanent global
form, the applicable prospectus supplement will describe any circumstances
under which beneficial owners of interests in any such permanent global senior
debt security may exchange their interests for senior debt securities of the
series and of like tenor and principal amount in any authorized form and
denomination. No bearer security delivered in exchange for a portion of a
permanent global senior debt security may be mailed or otherwise delivered to
any location in the United States in connection with the exchange. (Section
305)

   A person having a beneficial interest in a permanent global senior debt
security will, except with respect to payment of principal of and any premium
and interest on the permanent global senior debt security, be treated as a
holder of the principal amount of outstanding senior debt securities
represented by the permanent global senior debt security as is specified in a
written statement of:

  .  the holder of the permanent global senior debt security, or

  .  in the case of a permanent global senior debt security in bearer form,
     the operator of Euroclear or Clearstream Luxembourg,

which is produced to the trustee by such person. (Section 203) Principal of and
any premium and interest on a permanent global senior debt security will be
payable in the manner described in the applicable prospectus supplement.

                                       14

Certain Limitations

   The indenture contains the covenants and limitations summarized below. These
covenants and limitations will be applicable, unless waived or amended, so long
as any of the senior debt securities are outstanding, unless stated otherwise
in the prospectus supplement.

   Liens. Alcoa covenants that it will not create, incur, assume or guarantee,
and will not permit any Restricted Subsidiary to create, incur, assume or
guarantee, any indebtedness for borrowed money secured by a mortgage, security
interest, pledge, charge or similar encumbrance ("mortgages") upon any
Principal Property of Alcoa or any Restricted Subsidiary or upon any shares of
stock or indebtedness of any Restricted Subsidiary without equally and ratably
securing the senior debt securities. The foregoing restriction, however, will
not apply to:

  .  mortgages on property, shares of stock or indebtedness of any
     corporation existing at the time such corporation becomes a Restricted
     Subsidiary;

  .  mortgages on property existing at the time of acquisition of such
     property by Alcoa or a Restricted Subsidiary or mortgages to secure the
     payment of all or any part of the purchase price of such property upon
     the acquisition or to secure any indebtedness incurred before, at the
     time of, or within 180 days after, the acquisition of such property for
     the purpose of financing all or any part of the purchase price thereof,
     or mortgages to secure the cost of improvements to such acquired
     property;

  .  mortgages to secure indebtedness of a Restricted Subsidiary to Alcoa or
     another Restricted Subsidiary;

  .  mortgages existing at the date of the indenture;

  .  mortgages on property of a corporation existing at the time such
     corporation is merged into or consolidated with Alcoa or a Restricted
     Subsidiary or at the time of a sale, lease, or other disposition of the
     properties of a corporation as an entirety or substantially as an
     entirety to Alcoa or a Restricted Subsidiary;

  .  certain mortgages in favor of governmental entities; or

  .  extensions, renewals or replacements of any mortgage referred to in the
     above listed exceptions. (Section 1009)

   Notwithstanding the restrictions outlined in the preceding paragraph, Alcoa
or any Restricted Subsidiary will be permitted to create, incur, assume or
guarantee any indebtedness secured by a mortgage without equally and ratably
securing the senior debt securities, if after giving effect thereto, the
aggregate amount of all indebtedness so secured by mortgages, not including
mortgages permitted under the listed exceptions above, does not exceed 10% of
Consolidated Net Tangible Assets. (Section 1009)

   Sale and Leaseback Arrangements. Alcoa covenants that it will not, nor will
it permit any Restricted Subsidiary to, enter into any arrangement with any
person providing for the leasing to Alcoa or any Restricted Subsidiary of
Principal Property, where such Principal Property has been or is to be sold or
transferred by Alcoa or such Restricted Subsidiary to such person, unless
either:

  .  Alcoa or such Restricted Subsidiary would be entitled to create, incur,
     assume or guarantee indebtedness secured by a mortgage on such Principal
     Property at least equal in amount to the Attributable Debt with respect
     to such arrangement, without equally and ratably securing the senior
     debt securities pursuant to the limitation in the indenture on liens; or

  .  Alcoa applies an amount equal to the greater of the net proceeds of such
     sale or the Attributable Debt with respect to such arrangement to the
     retirement of indebtedness that matures more than twelve months after
     the creation of such indebtedness.

                                       15
<PAGE>

   This restriction on sale and leaseback transactions does not apply to any
transaction:

  .  involving a lease for a term of not more than three years; or

  .  between Alcoa and a Restricted Subsidiary or between Restricted
     Subsidiaries. (Section 1010)

   Highly leveraged transactions. The indenture does not contain provisions
that would afford protection to the holders of the senior debt securities in
the event of a highly leveraged transaction involving Alcoa.

Certain Definitions

   The following are definitions of capitalized words used in this summary.
These and other definitions are set forth in their entirety in the indenture.

   "Attributable Debt" when used in connection with a sale and leaseback
transaction referred to above means, at the time of determination, the lesser
of:

  .  the fair value of such property as determined by Alcoa's board of
     directors; or

  .  the present value, discounted at the annual rate of 9%, compounded semi-
     annually, of the obligation of the lessee for net rental payments during
     the remaining term of the lease, including any period for which such
     lease has been extended.

   "Bearer Security" means any senior debt security established under the
indenture that is payable to bearer.

   "Book-entry security" means a registered security bearing the legend
specified in Section 204 of the indenture, evidencing all or part of a series
of senior debt securities, issued to the depository for such series or its
nominee, and registered in the name of such depository or nominee. Book-entry
securities will not be deemed to be securities in global form for purposes of
Sections 201 and 203 and Article Three of the indenture.

   "Common Stock" includes any stock of any class of Alcoa that has no
preference in respect of dividends or of amounts payable in the event of any
voluntary or involuntary liquidation, dissolution or winding-up of Alcoa and
which is not subject to redemption by Alcoa. However, subject to the
provisions of Section 1511 of the indenture, shares issuable on conversion of
senior debt securities will include only shares of the class designated as
common stock of Alcoa at September 30, 1993 or shares of any class or classes
resulting from any reclassification or reclassifications thereof and which
have no preference in respect of dividends or of amounts payable in the event
of any voluntary or involuntary liquidation, dissolution or winding-up of
Alcoa and which are not subject to redemption by Alcoa. If at any time there
is more than one such resulting class, the shares of each such class then so
issuable will be substantially in the proportion that the total number of
shares of each such class resulting from all such reclassifications bears to
the total number of shares of all such classes resulting from all such
reclassifications.

   "Consolidated Net Tangible Assets" means, as of any particular time, the
aggregate amount of assets, less applicable reserves and other properly
deductible items, adjusted for inventories on the basis of cost, before
application of the "last-in first-out" method of determining cost, or current
market value, whichever is lower, and deducting therefrom:

  .  all current liabilities except for:

    .  notes and loans payable,

    .  current maturities of long-term debt, and

    .  current maturities of obligations under capital leases; and

  .  all goodwill, tradenames, patents, unamortized debt discount and
     expenses, to the extent included in such aggregate amount of assets, and
     other like intangibles, all as set forth on the most recent consolidated
     balance sheet of Alcoa and its consolidated Subsidiaries and computed in
     accordance with generally accepted accounting principles.

                                      16
<PAGE>

   "Principal Property" means any manufacturing plant or manufacturing facility
that is:

  .  owned by Alcoa or any Restricted Subsidiary; and

  .  located within the continental United States of America.

However, any plant that, in the opinion of Alcoa's board of directors, is not
of material importance to the total business conducted by Alcoa and the
Restricted Subsidiaries taken as a whole will not constitute a Principal
Property.

   "Restricted Subsidiary" means any Subsidiary substantially all the property
of which is located within the continental United States, but excluding any
Subsidiary that:

  .  is principally engaged in leasing or in financing receivables, or

  .  is principally engaged in financing Alcoa's operations outside the
     continental United States, or

  .  principally serves as a partner in a partnership.

   "Subsidiary" means any corporation of which at least a majority of the
outstanding stock having the voting power to elect a majority of the board of
directors of such corporation as at the time is owned, directly or indirectly,
by Alcoa or by one or more Subsidiaries, or by Alcoa and one or more
Subsidiaries.

Events of Default

   Unless otherwise provided in the applicable prospectus supplement, the
following are events of default under the indenture with respect to senior debt
securities:

  (a)  failure to pay any interest when due, and this failure continues for
       30 days;

  (b)  failure to pay any principal or premium when due;

  (c)  failure to deposit any sinking fund payment when due and this failure
       continues for 30 days;

  (d)  failure to perform any other covenant of Alcoa in the indenture (other
       than a covenant included in the indenture solely for the benefit of a
       series of senior debt securities other than that series), and this
       failure continues for 90 days after written notice as provided in the
       indenture;

  (e)  default resulting in acceleration of any indebtedness for money
       borrowed by Alcoa under the terms of the instrument(s) under which
       such indebtedness is issued or secured if such acceleration is not
       rescinded or annulled within 10 days after written notice as provided
       in the indenture, provided that, the resulting event of default under
       the indenture will be cured or waived if such other default is cured
       or waived;

  (f)  certain events in bankruptcy, insolvency or reorganization involving
       Alcoa; and

  (g)  any other event of default provided with respect to senior debt
       securities of a series. (Section 501)

   If an event of default with respect to senior debt securities occurs and is
continuing, either the trustee or the holders of at least 25% in aggregate
principal amount of the outstanding senior debt securities of that series by
notice as provided in the indenture may declare the principal amount (or, if
the senior debt securities of that series are original issue discount
securities, such portion of the principal amount as may be specified in the
terms of that series) of all the senior debt securities of that series to be
due and payable immediately. At any time after a declaration of acceleration
with respect to senior debt securities of any series has been made, but before
a judgment or decree for payment of money has been obtained by the trustee, the
holders of a majority in aggregate principal amount of the outstanding senior
debt securities of that series may, under certain circumstances, rescind and
annul such acceleration. (Section 502)

   Subject to the duty of the trustee during default to act with the required
standard of care, the trustee will be under no obligation to exercise any of
its rights or powers under the indenture at the request or direction of

                                       17
<PAGE>

any of the holders, unless such holders have offered to the trustee reasonable
indemnity. (Sections 601 and 603) The holders of a majority in aggregate
principal amount of the outstanding senior debt securities of any series will
have the right to direct the time, method and place of conducting any
proceeding for any remedy available to the trustee, or exercising any trust or
power conferred on the trustee, with respect to the senior debt securities of
that series. (Section 512)

Conversion and Exchange Rights

   The senior debt securities of any series may be convertible into or
exchangeable for other securities of Alcoa or another issuer on the terms and
subject to the conditions set forth in the applicable prospectus supplement.

Defeasance and Covenant Defeasance

   Unless otherwise indicated in the applicable prospectus supplement with
respect to the senior debt securities of a series, Alcoa, at its option:

  (a)  will be discharged from any and all obligations in respect of the
       senior debt securities of that series, except for certain obligations
       to:

    .  issue temporary senior debt securities pending preparation of
       definitive senior debt securities,

    .  register the transfer or exchange of senior debt securities of such
       series,

    .  replace stolen, lost or mutilated senior debt securities of such
       series, and

    .  maintain paying agents and hold moneys for payment in trust,

   or

  (b)  need not comply with the covenants that are set forth under "Certain
       Limitations" and "Consolidation, Merger and Sale of Assets," and the
       occurrence of an event described under clause (d) of "Events of
       Default" with respect to any defeased covenant and clauses (e) and (g)
       of "Events of Default" will no longer be events of default,

if, in each case, Alcoa irrevocably deposits with the trustee, in trust, money
and/or U.S. government obligations that through the scheduled payment of
interest thereon and principal thereof in accordance with their terms will
provide money in an amount sufficient to pay all the principal of and any
premium and interest on the senior debt securities of such series on the dates
such payments are due, which may include one or more redemption dates
designated by Alcoa, in accordance with the terms of the indenture and the
senior debt securities. (Sections 1301, 1302, 1303 and 1304) The trust may only
be established if, among other things:

  .  no event of default, or event that with the giving of notice or lapse of
     time, or both, would become an event of default, under the indenture has
     occurred and is continuing on the date of such deposit, and no event of
     default, or event that with the giving of notice or lapse of time, or
     both, would become an event of default, under clause (f) of "Events of
     Default" has occurred and is continuing at any time during the period
     ending on the 91st day following such date of deposit, and

  .  Alcoa has delivered an opinion of counsel based, in the event of a
     defeasance of the type described in clause (a) above, upon a ruling from
     the Internal Revenue Service or a change in applicable Federal income
     tax law from the date of the indenture, to the effect that the holders
     of the senior debt securities will not recognize income, gain or loss
     for Federal income tax purposes as a result of such deposit or
     defeasance and will be subject to Federal income tax in the same manner
     as if such defeasance had not occurred. (Section 1304)

If Alcoa omits to comply with its remaining obligations under the indenture
after a defeasance of the indenture with respect to the senior debt securities
of any series as described under clause (b) above and the senior debt

                                       18
<PAGE>

securities of such series are declared due and payable because of the
occurrence of any undefeased event of default, the amount of money and/or U.S.
government obligations on deposit with the trustee may be insufficient to pay
amounts due on the senior debt securities of such series at the time of the
acceleration resulting from such event of default. However, Alcoa will remain
liable in respect of such payments.

Meetings, Modification and Waiver

   Alcoa and the trustee may make modifications and amendments of the indenture
with the consent of the holders of not less than 66 2/3% in aggregate principal
amount of the outstanding senior debt securities of each series affected by the
modification or amendment. However, Alcoa and the trustee may not make any of
the following modifications or amendments without the consent of the holder of
each outstanding senior debt security affected:

  .  change the Stated Maturity of the principal of, or any installment of
     principal of or interest on, any senior debt security;

  .  reduce the principal amount of, or premium or interest on, any senior
     debt security;

  .  change any obligation of Alcoa to pay additional amounts;

  .  reduce the amount of principal of an original issue discount security
     payable upon acceleration of the maturity thereof;

  .  change the coin or currency in which any senior debt security or any
     premium or interest thereon is payable;

  .  impair the right to institute suit for the enforcement of any payment on
     or with respect to any senior debt security;

  .  reduce the percentage in principal amount of outstanding senior debt
     securities of any series, the consent of whose holders is required for
     modification or amendment of the indenture or for waiver of compliance
     with certain provisions of such indenture or for waiver of certain
     defaults;

  .  reduce the requirements contained in the indenture for quorum or voting;

  .  change any obligation of Alcoa to maintain an office or agency in the
     places and for the purposes required by the indenture; or

  .  modify any of the above provisions. (Section 902)

   The holders of at least 66 2/3% of the outstanding senior debt securities of
a series may waive compliance by Alcoa with certain restrictive provisions of
the indenture. (Section 1012) The holders of not less than a majority in
aggregate principal amount of the outstanding senior debt securities of each
series may, on behalf of all holders of senior debt securities of that series
and any coupons appertaining thereto, waive any past default under the
indenture with respect to senior debt securities of that series, except a
default:

  .  in the payment of principal of, or any premium or interest on, any
     senior debt security of the series; and

  .  in respect of a covenant or provision of the indenture that cannot be
     modified or amended without the consent of the holder of each
     outstanding senior debt security of the series affected. (Section 513)

   In determining whether the holders of the requisite principal amount of the
outstanding senior debt securities have given any request, demand,
authorization, direction, notice, consent or waiver thereunder or are present
at a meeting of holders of senior debt securities for quorum purposes:

  .  the principal amount of an original issue discount security that will be
     deemed to be outstanding will be the amount of its principal that would
     be due and payable as of the date of such determination upon
     acceleration of its maturity;

                                       19
<PAGE>

  .  the principal amount of a senior debt security denominated in a foreign
     currency or currencies will be the U.S. dollar equivalent, determined on
     the date of original issuance of that security, of the principal amount
     of the senior debt security (or, in the case of an original issue
     discount security, the U.S. dollar equivalent, determined on the date of
     original issuance of the senior debt security, of the amount determined
     as provided above); and

  .  senior debt securities owned by Alcoa or an affiliate of Alcoa will not
     be deemed outstanding. (Section 101)

   The indenture contains provisions for convening meetings of the holders of
senior debt securities of a series if senior debt securities of that series are
issuable as bearer securities. (Section 1401) A meeting may be called at any
time by the trustee, and also, upon request, by Alcoa or the holders of at
least 10% in principal amount of the outstanding senior debt securities of a
series, in any case upon notice given in accordance with "Notices" below.
(Section 1402) To be entitled to vote at any meeting of holders of senior debt
securities of any series, a person must be:

  .  a holder of one or more outstanding senior debt securities of the
     series; or

  .  a person appointed by an instrument in writing as proxy of a holder,
     including proxies given to beneficial owners of book-entry securities by
     the depository or its nominee. (Section 1403)

   Except for any consent that must be given by the holder of each outstanding
senior debt security affected thereby, as described above,

  .  any resolution presented at a meeting or adjourned meeting at which a
     quorum is present may be adopted by the affirmative vote of the holders
     of a majority in principal amount of the outstanding senior debt
     securities of that series;

  .  any resolution with respect to any consent or waiver that may be given
     by the holders of not less than 66 2/3% in principal amount of the
     outstanding senior debt securities of a series may be adopted at a
     meeting or an adjourned meeting at which a quorum is present only by the
     affirmative vote of 66 2/3% in principal amount of the outstanding
     senior debt securities of that series; and

  .  any resolution with respect to any request, demand, authorization,
     direction, notice, consent, waiver or other action that may be made,
     given or taken by the holders of a specified percentage, which is less
     than a majority, in principal amount of outstanding senior debt
     securities of a series may be adopted at a meeting or adjourned meeting
     duly reconvened at which a quorum is present by the affirmative vote of
     the holders of such specified percentage in principal amount of the
     outstanding senior debt securities of that series.

Any resolution passed or decision taken at any meeting of holders of senior
debt securities of any series duly held in accordance with the indenture will
be binding on all holders of senior debt securities of that series and the
related coupons.

   The quorum at any meeting called to adopt a resolution, and at any
reconvened meeting, will be persons holding or representing a majority in
principal amount of the outstanding senior debt securities of a series;
provided, however, that if any action is to be taken at such meeting with
respect to a consent or waiver that may be given by the holders of not less
than 66 2/3% in principal amount of the outstanding senior debt securities of a
series, the persons holding or representing 66 2/3% in principal amount of the
outstanding senior debt securities of such series will constitute a quorum.
(Section 1404)

Consolidation, Merger and Sale of Assets

   Alcoa may, without the consent of the holders of any of the outstanding
senior debt securities under the indenture, consolidate or merge with or into,
or transfer or lease its assets substantially as an entirety to, any person
that is a corporation, partnership or trust organized and validly existing
under the laws of any domestic

                                       20
<PAGE>

jurisdiction, or may permit any such person to consolidate with or merge into
Alcoa or convey, transfer or lease its properties and assets substantially as
an entirety to Alcoa, provided that:

  .  any successor person assumes Alcoa's obligations on the senior debt
     securities and under the indenture;

  .  after giving effect to the transaction, no event of default, and no
     event that, after notice or lapse of time, would become an event of
     default, has occurred and is continuing; and

  .  certain other conditions are met. (Section 801)

Notices

   Except as otherwise provided in the indenture, notices to holders of bearer
securities will be given by publication at least twice in a daily newspaper in
the City of New York and in such other city or cities as may be specified in
such senior debt securities and described in the applicable prospectus
supplement. Notices to holders of registered securities will be given by mail
to the addresses of such holders as they appear in the security register.
(Sections 101 and 106)

Title

   Title to any bearer securities and any coupons will pass by delivery. Alcoa,
the trustee and any agent of Alcoa or the trustee may treat the bearer of any
bearer security and the bearer of any coupon and the registered owner of any
registered security as the absolute owner thereof, whether or not the senior
debt security or coupon is overdue and notwithstanding any notice to the
contrary, for the purpose of making payment and for all other purposes.
(Section 308)

Replacement of Securities and Coupons

   Alcoa will replace any mutilated senior debt security or a senior debt
security with a mutilated coupon at the expense of the holder upon surrender of
the senior debt security to the security registrar.

   Alcoa will replace senior debt securities or coupons that become destroyed,
stolen or lost at the expense of the holder upon delivery to the trustee of the
senior debt security and coupons or evidence of the destruction, loss or theft
thereof satisfactory to Alcoa and the trustee. If any coupon becomes destroyed,
stolen or lost, that coupon will be replaced by issuance of a new senior debt
security in exchange for the senior debt security to which that coupon is
attached. In the case of a destroyed, lost or stolen senior debt security or
coupon, an indemnity satisfactory to the trustee and Alcoa may be required at
the expense of the holder of such senior debt security or coupon before a
replacement senior debt security will be issued. (Section 306)

Governing Law

   The indenture, the senior debt securities and the coupons will be governed
by, and construed in accordance with, the laws of the Commonwealth of
Pennsylvania, except to the extent that the Trust Indenture Act applies.

                  DESCRIPTION OF SUBORDINATED DEBT SECURITIES

   The following description sets forth certain general terms and provisions of
the subordinated debt securities that Alcoa may offer. The particular terms of
the subordinated debt securities and the extent, if any, to which the general
provisions may apply to the subordinated debt securities will be described in
the related prospectus supplement.

   The subordinated debt securities may be issued under an indenture between
Alcoa and Chase Manhattan Trust Company, N.A., as trustee, or such other
trustee that is named in a prospectus supplement. The form of the indenture has
been filed with the SEC as an exhibit to the registration statement of which
this prospectus is a part. The following summary of certain provisions of the
indenture and the subordinated debt securities is not meant to be complete. For
more information, you should refer to the full text of the indenture and the
subordinated debt securities, including the definitions of terms used and not
defined in this prospectus or the related prospectus supplement.

General

   The subordinated debt securities will be unsecured and will rank junior and
be subordinate in right of payment to all Senior Debt (as defined below) of
Alcoa. The indenture does not limit the incurrence or issuance of other secured
or unsecured debt of Alcoa, whether under the indenture or any existing or
other indenture that Alcoa may enter into in the future or otherwise. See
"Subordination."

   The subordinated debt securities will not be subject to any sinking fund
provision.

   A prospectus supplement will describe the following terms of the
subordinated debt securities Alcoa may offer:

  .  the specific designation, aggregate principal amount and purchase price;

  .  any limit on the aggregate principal amount;

  .  the date(s) on which the principal is payable and any right to extend
     such date(s);

  .  any rate(s) at which the subordinated debt securities will bear interest
     or the method of calculating any interest rate(s);

  .  the date(s) from which interest will accrue, the interest payment dates
     on which interest will be payable or the manner of determination of
     interest payment dates and the record dates for the determination of
     holders to whom interest is payable on any interest payment dates;

  .  any right to defer payments of interest by extending the interest
     payment periods and the duration of such extensions;

  .  the period(s) within which, the price(s) at which, and the terms and
     conditions upon which, the subordinated debt securities may be redeemed,
     in whole or in part, at the option of Alcoa;

  .  any obligation of Alcoa to redeem or purchase the subordinated debt
     securities at the option of the holder thereof and the period(s) within
     which, the price(s) at which, and the terms and conditions upon which,
     the subordinated debt securities will be redeemed or purchased, in whole
     or part, under such obligation;

                                       22
<PAGE>

  .  any applicable United States Federal income tax consequences, including
     whether and under what circumstances Alcoa will pay additional amounts
     on the subordinated debt securities held by a person who is not a U.S.
     person in respect of any tax, assessment or governmental charge withheld
     or deducted and, if so, whether Alcoa will have the option to redeem the
     subordinated debt securities rather than pay such additional amounts;

  .  the form of the subordinated debt securities;

  .  if other than denominations of $1,000 or any integral multiple thereof,
     the denominations in which the subordinated debt securities will be
     issuable;

  .  any and all other terms, including any modifications of or additions to
     the events of default or covenants, and any terms that may be required
     by or advisable under applicable laws or regulations not inconsistent
     with the indenture;

  .  the terms and conditions upon which the subordinated debt securities may
     be convertible into or exchanged for other securities of Alcoa or
     another issuer; and

  .  whether the subordinated debt securities are issuable as a global
     security, and in such case, the identity of the depository.

   Unless otherwise indicated in the applicable prospectus supplement, the
subordinated debt securities will be issued in United States dollars in fully
registered form without coupons. No service charge will be made for any
transfer or exchange of any subordinated debt securities, but Alcoa may require
payment of a sum sufficient to cover any tax or other governmental charge
payable in connection with a transfer or exchange.

Global Securities

   If any subordinated debt securities are represented by one or more global
securities, the applicable prospectus supplement will describe any
circumstances under which beneficial owners of interests in any global security
may exchange those interests for subordinated debt securities of like tenor and
principal amount in any authorized form and denomination. Principal of, and any
premium and interest on, a global security will be payable in the manner
described in the applicable prospectus supplement.

   The specific terms of the depositary arrangement regarding any portion of
subordinated debt securities to be represented by a global security will be
described in the applicable prospectus supplement.

Payment and Paying Agents

   Payments on subordinated debt securities represented by a global security
will be made to the depository for the subordinated debt securities. If
subordinated debt securities are issued in definitive form, then the following
will take place at the corporate office of the trustee in Pittsburgh,
Pennsylvania or at the office of such paying agent(s) as Alcoa may designate:

  .  payment of principal of and any premium and interest on the subordinated
     debt securities;

  .  registration of the transfer of the subordinated debt securities; and

  .  the exchange of the subordinated debt securities into subordinated debt
     securities of other denominations of a like aggregate principal amount.

However, at the option of Alcoa, payment of any interest may be made:


                                       23
<PAGE>

  .  by check mailed to the address of the person entitled thereto as such
     address appears in the securities register; or

  .  by wire transfer to an account maintained by the person entitled thereto
     as specified in the securities register, provided that proper transfer
     instructions have been received by the regular record date.

Payment of any interest on subordinated debt securities will be made to the
person in whose name the subordinated debt securities are registered at the
close of business on the regular record date for the interest, except in the
case of defaulted interest. Unless otherwise set forth in the applicable
prospectus supplement, the regular record date for the interest payable on any
interest payment date will be the 15th day, whether or not a business day, next
preceding such interest payment date. Alcoa may at any time designate
additional paying agents or rescind the designation of any paying agent.
(Section 2.3)

   Any monies deposited with the trustee or any paying agent or then held by
Alcoa in trust for the payment of the principal of and any premium or interest
on any subordinated debt securities and remaining unclaimed for two years after
such principal and premium, if any, or interest has become due and payable
will, at the request of Alcoa, be repaid to Alcoa. Thereafter, the holder of
such subordinated debt securities may look, as a general unsecured creditor,
only to Alcoa for payment. (Section 10.3)

Modification of Indenture

   Alcoa and the trustee may, without the consent of the holders of
subordinated debt securities, amend, waive or supplement the indenture for
specified purposes, including, among other things:

  .  curing ambiguities, defects or inconsistencies, provided that any such
     action does not materially adversely affect the interest of the holders
     of the subordinated debt securities; and

  .  qualifying, or maintaining the qualification of, the indenture under the
     Trust Indenture Act. (Section 9.1)

   Alcoa and the trustee may, with the consent of the holders of not less than
a majority in principal amount of the outstanding subordinated debt securities,
modify the indenture in a manner affecting the rights of the holders of the
subordinated debt securities. However, no such modification may, without the
consent of the holder of each outstanding subordinated debt security so
affected:

  .  change the stated maturity of the subordinated debt securities;

  .  reduce the principal amount thereof;

  .  reduce the rate or extend the time of payment of interest thereon, other
     than deferrals of the payments of interest during any extension period
     as described in any applicable prospectus supplement;

  .  reduce the premium payable upon redemption;

  .  impair any right to institute suit for the enforcement of any such
     payment;

  .  adversely affect the subordination provisions of the indenture or any
     right to convert or exchange any subordinated debt securities; or

  .  reduce the percentage of principal amount of subordinated debt
     securities, the holders of which are required to consent to any such
     modification of the indenture. (Section 9.2)

Events of Default

   Any one or more of the following described events that has occurred and is
continuing constitutes an event of default with respect to the subordinated
debt securities:

  (a)  failure for 30 days to pay any interest when due (subject to the
       deferral of any due date in the case of an extension period);


                                       24
<PAGE>

  (b)  failure to pay any principal or premium when due whether at maturity,
       upon redemption, by declaration or otherwise;

  (c)  failure by Alcoa to deliver securities upon an appropriate election by
       holders of subordinated debt securities to convert their subordinated
       debt securities into those securities;

  (d)  failure to observe or perform certain other covenants contained in the
       indenture for 90 days after written notice to Alcoa from the trustee
       or to the trustee and Alcoa from the holders of at least 25% in
       aggregate outstanding principal amount of the subordinated debt
       securities; or

  (e)  certain events in bankruptcy, insolvency or reorganization of Alcoa.
       (Section 5.1)

   The holders of a majority in aggregate outstanding principal amount of the
subordinated debt securities of any series will have the right to direct the
time, method and place of conducting any proceeding for any remedy available to
the trustee or exercising any trust or power conferred on the trustee
consistent with the indenture with respect to the subordinated debt securities
of that series. (Section 5.12) If an event of default with respect to
subordinated debt securities occurs and is continuing, either the trustee or
the holders of not less than 25% in aggregate principal amount of the
outstanding subordinated debt securities of that series may declare the
principal of all of the subordinated debt securities of that series due and
payable immediately. At any time after a declaration of acceleration with
respect to subordinated debt securities of any series has been made, but before
a judgment or decree for payment of money has been obtained by the trustee, the
holders of a majority in aggregate outstanding principal amount of the
subordinated debt securities of that series may annul and rescind such
declaration if the default, other than the non-payment of the principal of the
subordinated debt securities which has become due solely by such acceleration,
has been cured or waived, and a sum sufficient to pay all matured installments
of interest and principal due, otherwise than by acceleration, has been
deposited with the trustee. (Section 5.2)

   The holders of a majority in aggregate outstanding principal amount of the
subordinated debt securities of any series may, on behalf of the holders of all
the subordinated debt securities of that series, waive any past default under
the indenture with respect to that series. However, they may not waive:

  .  a default in the payment of principal or interest, unless such default
     has been cured and a sum sufficient to pay all matured installments of
     interest and principal due otherwise than by acceleration has been
     deposited with the trustee; or

  .  a default in respect of a covenant or provision that under the indenture
     cannot be modified or amended without the consent of the holder of each
     outstanding subordinated debt security. (Section 5.13)

Alcoa is required to file annually with the trustee a certificate as to whether
or not Alcoa is in compliance with all the conditions and covenants applicable
to it under the indenture. (Section 10.5)

Consolidation, Merger, Sale of Assets and Other Transactions

   Alcoa may not consolidate with or merge into any other person or convey,
transfer or lease its properties and assets substantially as an entirety to any
person, and no person may consolidate with or merge into Alcoa or convey,
transfer or lease its properties and assets substantially as an entirety to
Alcoa, unless:

  .  if Alcoa consolidates with or merges into another person or conveys,
     transfers or leases its properties and assets substantially as an
     entirety to any person, the successor person is organized under the laws
     of the United States or any state or the District of Columbia, and such
     successor person expressly assumes Alcoa's obligations on the
     subordinated debt securities and under the indenture;

  .  immediately after giving effect thereto, no event of default, and no
     event that, after notice or lapse of time or both, would become an event
     of default, has happened and is continuing; and

  .  certain other conditions as prescribed in the indenture are met.
     (Section 8.1)

                                       25
<PAGE>

Highly Leveraged Transactions

   The general provisions of the indenture do not afford holders of the
subordinated debt securities protection in the event of a highly leveraged or
other transaction involving Alcoa that may adversely affect holders of the
subordinated debt securities.

Satisfaction and Discharge

   The indenture will cease to be of further effect, and Alcoa will be deemed
to have satisfied and discharged the indenture, when, among other things:

  .  all subordinated debt securities not previously delivered to the trustee
     for cancellation have become due and payable or will become due and
     payable at their stated maturity within one year or are to be properly
     called for redemption within one year; and

  .  Alcoa irrevocably deposits or causes to be deposited with the trustee as
     trust funds money and/or U.S. government obligations sufficient to pay
     and discharge the entire indebtedness on the subordinated debt
     securities for the principal and any premium, interest and other sums
     payable under the indenture on the dates such payments are due. (Section
     4.1)

Subordination

   Any subordinated debt securities issued under the indenture will be
subordinate and junior in right of payment to all Senior Debt (as defined
below) of Alcoa whether existing at the date of the indenture or subsequently
incurred. Upon any payment or distribution of assets of Alcoa to creditors upon
any:

  .  liquidation;

  .  dissolution;

  .  winding-up;

  .  reorganization;

  .  assignment for the benefit of creditors;

  .  marshaling of assets or any bankruptcy;

  .  insolvency; or

  .  debt restructuring or similar proceedings in connection with any
     insolvency or bankruptcy proceeding of Alcoa,

the holders of Senior Debt will first be entitled to receive payment in full of
principal of and any premium and interest on such Senior Debt before the
holders of the subordinated debt securities will be entitled to receive or
retain any payment in respect of the principal of and any premium or interest
on the subordinated debt securities. (Sections 12.1 and 12.2)

   Upon the acceleration of the maturity of any subordinated debt securities,
the holders of all Senior Debt outstanding at the time of such acceleration
will first be entitled to receive payment in full of all amounts due thereon,
including any amounts due upon acceleration, before the holders of subordinated
debt securities will be entitled to receive or retain any payment in respect of
the principal of or any premium or interest on the subordinated debt
securities. (Section 12.1)

   No payments on account of principal, or any premium or interest, in respect
of the subordinated debt securities may be made if:

  .  there has occurred and is continuing a default in any payment with
     respect to Senior Debt;

                                       26
<PAGE>

  .  there has occurred and is continuing an event of default with respect to
     any Senior Debt resulting in the acceleration of the maturity thereof;
     or

  .  any judicial proceeding is pending with respect to any such default or
     event of default with respect to any Senior Debt. (Section 12.3)

   "Debt" means, with respect to any person, whether recourse is to all or a
portion of the assets of such person and whether or not contingent:

  .  every obligation of such person for money borrowed;

  .  every obligation of such person evidenced by bonds, debentures, notes or
     other similar instruments, including obligations incurred in connection
     with the acquisition of property, assets or businesses;

  .  every reimbursement obligation of such person with respect to letters of
     credit, bankers' acceptances or similar facilities issued for the
     account of such person;

  .  every obligation of such person issued or assumed as the deferred
     purchase price of property or services, but excluding trade accounts
     payable or accrued liabilities arising in the ordinary course of
     business;

  .  every capital lease obligation of such person; and

  .  every obligation of the type referred to above of another person and all
     dividends of another person the payment of which, in either case, such
     person has guaranteed or for which such person is responsible or liable,
     directly or indirectly, as obligor or otherwise.

   "Senior Debt" means the principal of, and any premium and interest,
including interest accruing on or after the filing of any petition in
bankruptcy or for reorganization relating to Alcoa, whether or not such claim
for post-petition interest is allowed in such proceeding, on Debt of Alcoa,
whether incurred on, before or after the date of the indenture, unless the
instrument creating or evidencing the Debt or under which the Debt is
outstanding provides that obligations created by it are not superior in right
of payment to the subordinated debt securities.

   The indenture will place no limitation on the amount of additional Senior
Debt that may be incurred by Alcoa.

Governing Law

   The indenture and the subordinated debt securities will be governed by and
construed in accordance with the laws of the State of New York, except to the
extent that the Trust Indenture Act applies. (Section 1.12)

Information Concerning the Trustee

   Chase Manhattan Trust Company, N.A. will be the trustee under the indenture.
The trustee is not obligated to exercise any of its powers under the indenture
at the request of any holder of subordinated debt securities, unless the holder
offers to indemnify the trustee against any loss, liability or expense, and
then only to the extent required by the terms of the indenture. The trustee is
not required to expend or risk its own funds or otherwise incur personal
financial liability in the performance of its duties if the trustee reasonably
believes that repayment or adequate indemnity is not reasonably assured to it.
(Section 6.3) Alcoa and certain of its subsidiaries maintain deposit accounts
and conduct other banking transactions, including borrowings in the ordinary
course of business, with Chase Manhattan Trust Company, N.A. or its affiliates.

                                       27

Additional Provisions that may be Applicable to Subordinated Debt Securities

   Alcoa may issue a specific series of subordinated debt securities in
connection with the issuance by the Alcoa Trust of trust preferred securities.
See "Description of Trust Preferred Securities and Trust Guarantee" below. At
the time the Alcoa Trust issues trust preferred securities, it will invest the
proceeds from the issuance of such securities, together with the consideration
paid by Alcoa for the related trust common securities, in subordinated debt
securities. The subordinated debt securities held by the Alcoa Trust will be in
the principal amount equal to the aggregate stated liquidation amount of the
trust preferred securities plus Alcoa's concurrent investment in the related
trust common securities.

   So long as any of the trust preferred securities remain outstanding:

  .  no modification may be made to the indenture relating to the
     subordinated debt securities that adversely affects the holders of the
     trust preferred securities in any material respect;

  .  no termination of the indenture may occur, and no waiver of any event of
     default with respect to the subordinated debt securities or compliance
     with any covenant under the indenture may be effective, without the
     prior consent of the holders of at least a majority in aggregate
     liquidation amount of the trust preferred securities then outstanding
     unless and until the principal of and any premium on the subordinated
     debt securities and all accrued and unpaid interest thereon has been
     paid in full; and

  .  where a consent under the indenture would require the consent of each
     holder of subordinated debt securities, no such consent will be given by
     the Property Trustee without the prior consent of each holder of the
     trust preferred securities. (Sections 9.1 and 9.2)

   If an event of default occurs and is continuing, the Property Trustee will
have the right to declare the principal of and the interest on the subordinated
debt securities and any other amounts payable under the indenture to be due and
payable and to enforce its other rights as a creditor with respect to the
subordinated debt securities. (Section 5.2)

   Upon the occurrence and continuance of an event of default under the
indenture:

  .  the holders of at least 25% in aggregate liquidation amount of the trust
     preferred securities then outstanding will have the right to declare the
     principal of all the subordinated debt securities to be immediately due
     and payable if the trustee or the holders of not less than 25% in
     principal amount of the outstanding subordinated debt securities fail to
     make such declaration; and

  .  the holders of a majority in aggregate liquidation amount of the trust
     preferred securities then outstanding will have the right to annul and
     rescind such declaration if the holders of a majority in principal
     amount of the outstanding subordinated debt securities fail to annul and
     rescind such declaration as provided in the indenture. (Section 5.2)

   The holders of a majority in aggregate liquidation amount of the trust
preferred securities then outstanding will have the right to waive any past
default under the indenture if the holders of a majority in principal amount of
the outstanding subordinated debt securities fail to waive such past default as
provided in the indenture. (Section 5.13)

   Any consolidation, merger, conveyance, transfer or lease of Alcoa's
properties and assets substantially as an entirety permitted under the
indenture must also be permitted under the trust agreement and the trust
guarantee relating to the trust preferred securities. (Section 8.1)

   Under the indenture, Alcoa will pay all of the costs, expenses or
liabilities of the Alcoa Trust, other than obligations of the Alcoa Trust to
pay to the holders of any trust preferred securities or trust common securities
the amounts due under the terms of those securities. (Section 10.9)

                            DESCRIPTION OF WARRANTS

   Alcoa may issue warrants for the purchase of debt securities. Alcoa may
issue such warrants independently or together with any debt securities offered
by any prospectus supplement. Alcoa will issue warrants under one or more
warrant agreements between itself and a warrant agent that it will name in the
prospectus supplement. The form of proposed warrant agreement, including the
form of warrant certificates representing the warrants, is filed with the SEC
and incorporated by reference as an exhibit to the registration statement of
which this prospectus is a part. The following summary of the material
provisions of the warrants and the warrant agreement is not complete. You
should read the warrant agreement for provisions that may be important to you.

   The prospectus supplement will describe the terms of the warrants, the
warrant agreement and the warrant certificates, including the following:

  .  the designation, aggregate principal amount and terms of the debt
     securities purchasable upon exercise of the warrants;

  .  the designation and terms of any related debt securities with which the
     warrants are issued, and the number of warrants issued with each such
     debt security;

  .  the date, if any, on and after which the warrants and the related debt
     securities will be separately transferable;

  .  the principal amount of debt securities purchasable upon exercise of one
     warrant and the price at which such principal amount may be purchased
     upon such exercise;

  .  the date on which the right to exercise the warrants will commence and
     the date on which such right will expire; and

  .  whether the warrants represented by the warrant certificates will be
     issued in registered or bearer form, and if registered, where they may
     be transferred and registered.

   If the debt securities purchasable upon exercise of the warrants are
issuable in bearer form, the warrants may not be offered nor constitute an
offer to United States persons other than to offices outside the United States
of certain United States financial institutions. Moreover, bearer debt
securities issuable upon exercise of the warrants may not be issued to United
States persons other than to offices outside the United States of certain
United States financial institutions.

   The corporate trust office of the warrant agent or any other office
indicated in the prospectus supplement will be the place where warrant
certificates will be exchangeable for new warrant certificates of different
denominations and warrants may be exercised. Before the exercise of their
warrants, holders of warrants will not have any of the rights of holders of the
debt securities purchasable upon such exercise and will not be entitled to
payments of principal of, and any premium or interest on, the debt securities
purchasable upon exercise.

when, as and if declared by Alcoa's board of directors, out of legally
available funds, cumulative cash or other dividends at such rate(s) and on such
dates as the board of directors determines. The applicable prospectus
supplement will set forth this dividend right. Rates may be fixed or variable
or both. The board may not declare dividends in respect of any dividend period
on any series of Class B Stock unless all accrued dividends and the current
quarter yearly dividend on the Class A Stock are paid in full or the board
contemporaneously declares and sets apart such Class A Stock dividends. If
Alcoa has not declared and paid or set apart the full cumulative dividends on
shares of a series of Class B Stock, dividends thereon will be declared and
paid pro rata to the holders of the series. Alcoa will not pay interest on any
dividend payment on the Class A Stock or the Class B Stock which is in arrears.

   If Alcoa has not declared and paid or set apart when due full cumulative
dividends on any class or series of Class A Stock or Class B Stock, including
the current quarter yearly dividend for shares of Class A Stock, Alcoa may not
declare or pay any dividends on, or make other distributions on or make payment
on account of the purchase, redemption, or other retirement, of Alcoa common
stock. No restriction applies to Alcoa's repurchase or redemption of Class A
Stock or Class B Stock while there is any arrearage in the payment of dividends
or any applicable sinking fund installments on Class A Stock or Class B Stock.

Redemption

   Alcoa may redeem all or any part of the Class A Stock at any time at the
option of its board of directors. Such redemption will be at par, plus accrued
dividends. Alcoa must publish notice of such redemption in daily newspapers of
general circulation in New York City and in Pittsburgh, Pennsylvania, as well
as by mail to each record holder. Alcoa must give such notice not less than 30
days nor more than 60 days before the date fixed for redemption. If Alcoa
redeems only part of the Class A Stock, Alcoa will select the shares to be
redeemed pro rata or by lot, as Alcoa's board of directors determines.

   If notice of redemption has been given, from and after the redemption date
for the shares of Class A Stock called for redemption, the following will
occur, unless Alcoa fails to provide funds for payment of the redemption price:


                                       31
<PAGE>

  .  dividends on the shares of Class A Stock called for redemption will
     cease to accrue;

  .  such shares will no longer be deemed to be outstanding; and

  .  holders will have no further rights as shareholders of Alcoa, except the
     right to receive the redemption price.

   Holders will receive the redemption price for the Class A Stock when they
surrender the certificates representing such shares in accordance with the
redemption notice (including being properly endorsed or assigned for transfer,
if Alcoa's board of directors so requires and the notice so states). If Alcoa
redeems fewer than all of the shares represented by any certificate, Alcoa will
issue a new certificate representing the unredeemed shares, at no cost to the
certificate holder. All shares of Class A Stock which Alcoa redeems will be
cancelled and not reissued.

   The terms and conditions under which all or any part of any series of the
Class B Stock may be redeemed will be established by Alcoa's board of directors
before Alcoa issues such series of Class B Stock. Unless Alcoa's board of
directors determines otherwise, all shares of Class B Stock which Alcoa redeems
or otherwise acquires will return to the status of authorized but unissued
shares.

Liquidation Preference

   Upon any liquidation, dissolution or winding up of Alcoa, each holder of
Class A Stock will be entitled to receive, out of the assets of Alcoa available
for distribution to shareholders, $100 per share plus accrued and unpaid
dividends, before any distribution of assets is made to or set apart for the
holders of Class B Stock or common stock.

   Upon any liquidation, dissolution or winding up of Alcoa, the holders of
shares of each series of Class B Stock will be entitled to receive, out of the
assets of Alcoa available for distribution to shareholders, an amount fixed by
the board of directors plus any accrued and unpaid dividends, before any
distribution is made or set apart for holders of common stock, as described in
the prospectus supplement relating to the series of Class B Stock. If Alcoa's
assets are insufficient to pay the full amount payable on shares of each series
of Class B Stock in any case of liquidation, dissolution or winding up of
Alcoa, the holders of shares of the series of Class B Stock will share ratably
in any such distribution of assets of Alcoa in proportion to the full
respective preferential amounts to which they are entitled. Once holders of
shares of the series of Class B Stock are paid the full preferential amounts to
which they are entitled, they will not be entitled to participate any further
in any distribution of assets by Alcoa, unless indicated otherwise in the
applicable prospectus supplement. A consolidation or merger of Alcoa with one
or more corporations will not be deemed to be a liquidation, dissolution or
winding up of Alcoa.

Conversion and Exchange Rights

   Class A Stock is not convertible or exchangeable for common stock. Any terms
on which shares of any series of Class B Stock are convertible into or
exchangeable for common stock will be set forth in the related prospectus
supplement. These terms may include provisions for conversion or exchange,
either mandatory, at the option of the holder, or at the option of Alcoa.

Voting Rights

   Except as indicated below or in the related prospectus supplement for a
particular series of the Class B Stock, or except as expressly required by
applicable law, the holders of Class A Stock and Class B Stock will not be
entitled to vote.

   Pennsylvania law requires that holders of outstanding shares of a particular
class or series of stock be entitled to vote as a class on an amendment to the
Articles of Incorporation that would do any of the following:

  .  authorize Alcoa's board of directors to fix and determine the relative
     rights and preferences as between any series of any preferred stock or
     special class of stock;

  .  change the preferences, limitations or other special rights of the
     shares of a class or series in a manner which is adverse to that class
     or series;

                                       32
<PAGE>

  .  authorize a new class or series of shares which has a preference as to
     dividends or assets which is senior to that of shares of a particular
     class or series; or

  .  increase the number of authorized shares of any particular class or
     series which has a preference as to dividends or assets which is senior
     in any respect to the shares of such class or series.

   The board of directors, under Alcoa's Articles of Incorporation, may limit
or eliminate the voting rights applicable to any series of Class B Stock before
the issuance of such series, except as otherwise required by law. Any one or
more series of the Class B Stock may be issued with such additional voting
rights, which will be exercisable only during extended periods of dividend
arrearages, as the board of directors may determine in order to qualify such
series for listing on a recognized stock exchange. Such rights may only be
granted if there are no shares of Class A Stock outstanding.

   Each full share of any series of the Class B Stock will be entitled to one
vote on matters on which holders of such series, together with holders of any
other series of Class B Stock, are entitled to vote as a single class.
Therefore, the voting power of each series will depend on the number of shares
in that series, and not on the liquidation preference or initial offering price
of such shares.

   Alcoa must obtain the consent of the holders of at least a majority of the
outstanding Class A Stock and Class B Stock, voting as a class, to do the
following:

  .  authorize any additional class of stock or increase the authorized
     number of shares of preferred stock or any class of stock which ranks on
     a parity with the Class A Stock or Class B Stock as to dividends or
     assets; or

  .  merge or consolidate with or into any other corporation if the
     corporation surviving or resulting from such merger or consolidation
     would have any authorized class of stock ranking senior to or on a
     parity with the Class A Stock or Class B Stock, except the same number
     of shares of stock with the same rights and preferences as the
     authorized stock of the corporation immediately before such merger or
     consolidation.

   So long as any shares of Class A Stock or Class B Stock remain outstanding,
Alcoa may not, without the consent of the holders of at least two-thirds of the
outstanding Class A Stock and Class B Stock, voting as a class:

  .  make any adverse change in the rights and preferences of the Class A
     Stock or Class B Stock. If such a change would affect any series of
     Class A Stock or Class B Stock adversely as compared to the effect on
     any other series of Class A Stock or Class B Stock, no such change may
     be made without the additional consent of the holders of at least two-
     thirds of the outstanding shares of such series of Class A Stock or
     Class B Stock;

  .  authorize any additional class of stock or increase the authorized
     number of shares of any class of stock which ranks senior to the Class A
     Stock or Class B Stock as to dividends or assets; or

  .  sell or otherwise part with control of all or substantially all of its
     property or business or voluntarily liquidate, dissolve or wind up its
     affairs.

                          DESCRIPTION OF COMMON STOCK

   Alcoa is authorized to issue 1,800,000,000 shares of common stock, par value
$1.00 per share. As of March 31, 2001, there were 864,060,712 shares of Alcoa
common stock outstanding. In addition, as of the same date, there were
60,513,826 shares of Alcoa common stock issued and held in Alcoa's treasury,
and 87,818,659 shares of Alcoa common stock reserved for issuance under various
incentive plans.

Dividend Rights

   Holders of Alcoa common stock are entitled to receive dividends as declared
by the Alcoa board of directors. However, no dividend will be declared or paid
on Alcoa's common stock until Alcoa has paid (or declared and set aside funds
for payment of) all dividends which have accrued on all classes of Alcoa's
preferred stock, including the current quarter yearly dividend on the Class A
Stock.

Voting Rights

   Holders of Alcoa common stock are entitled to one vote per share.

Liquidation Rights

   Upon any liquidation, dissolution or winding up of Alcoa, whether voluntary
or involuntary, after payments to holders of preferred stock of amounts
determined by the board of directors, plus any accrued dividends, Alcoa's
remaining assets will be divided among holders of Alcoa common stock. Under
Alcoa's Articles of Incorporation, neither the consolidation or merger of Alcoa
with or into one or more corporations or any share exchange or division
involving Alcoa will be deemed a liquidation, dissolution or winding up of
Alcoa.

Preemptive or Other Subscription Rights

   Holders of Alcoa common stock will not have any preemptive right to
subscribe for any securities of Alcoa.

Conversion and Other Rights

   No conversion, redemption or sinking fund provisions apply to Alcoa common
stock, and Alcoa common stock is not liable to further call or assessment by
Alcoa. All issued and outstanding shares of Alcoa common stock are fully paid
and non-assessable.

Other Matters

   Alcoa's Articles of Incorporation provide for the following:

  .  a classified board of directors with staggered three-year terms;

  .  special shareholder voting requirements to remove directors; and

  .  certain procedures relating to the nomination of directors, filling of
     vacancies and the vote required to amend or repeal any of these
     provisions.

   Alcoa's Articles of Incorporation also prohibit Alcoa's payment of "green-
mail," that is, payment of a premium in purchasing shares of its common stock
from a present or recent holder of 5% or more of the common stock, except with
the approval of a majority of the disinterested shareholders. This provision
and the classified board provision may be amended or repealed only with the
affirmative vote of at least 80% of the common stock. In addition, the Articles
of Incorporation limit or eliminate to the fullest extent permitted by

                                       34
<PAGE>

Pennsylvania law, as from time to time in effect, the personal liability of
Alcoa's directors for monetary damages, and authorize Alcoa, except as
prohibited by law, to indemnify directors, officers, employees and others
against liabilities and expenses incurred by them in connection with the
performance of their duties to Alcoa. The classified board article provision
and the anti-"greenmail" provision may have certain anti-takeover effects.

   Alcoa is governed by certain "anti-takeover" provisions in the Pennsylvania
Business Corporation Law (the "PCBL"). Chapter 25 of the PBCL contains several
anti-takeover provisions that apply to registered corporations such as Alcoa.
Section 2538 of the PBCL requires shareholder approval for certain transactions
between a registered corporation and an interested shareholder (generally, a
shareholder who owns 20% of the stock entitled to vote in an election of
directors). Section 2538 applies if an interested shareholder (together with
anyone acting jointly with such shareholder and any affiliates of such
shareholder):

  .  is to be a party to a merger or consolidation, a share exchange or
     certain sales of assets involving such corporation or one of its
     subsidiaries;

  .  is to receive a disproportionate amount of any of the securities of any
     corporation which survives or results from a division of the
     corporation;

  .  is to be treated differently from others holding shares of the same
     class in a voluntary dissolution of such corporation; or

  .  is to have his or her percentage of voting or economic share interest in
     such corporation materially increased relative to substantially all
     other shareholders in a reclassification.

   In such a case, the proposed transaction must be approved by the affirmative
vote of the holders of shares representing at least a majority of the votes
that all shareholders are entitled to cast with respect to such transaction.
Shares held by the interested shareholder are not included in calculating the
number of shares entitled to be cast, and the interested shareholder is not
entitled to vote on the transaction. This special voting requirement does not
apply if the proposed transaction has been approved in a prescribed manner by
the corporation's board of directors or if certain other conditions, including
the amount of consideration to be paid to certain shareholders, are satisfied
or the transaction involves certain subsidiaries.

   Section 2555 of the PBCL may also apply to a transaction between a
registered corporation and an interested shareholder, even if Section 2538 also
applies. Section 2555 prohibits a corporation from engaging in a business
combination with an interested shareholder unless one of the following
conditions is met:

  .  the board of directors has previously approved either the proposed
     transaction or the interested shareholder's acquisition of shares;

  .  the interested shareholder owns at least 80% of the stock entitled to
     vote in an election of directors and, no earlier than three months after
     the interested shareholder reaches the 80% level,

    .  the majority of the remaining shareholders approve the proposed
       transaction;

    .  shareholders receive a minimum "fair price" for their shares in the
       transaction; and

    .  the other conditions of Section 2556 of the PBCL are met;

  .  holders of all outstanding common stock approve the transaction;

  .  no earlier than 5 years after the interested shareholder acquired the
     20%, a majority of the remaining shares entitled to vote in an election
     of directors approve the transaction; or

  .  no earlier than 5 years after the interested shareholder acquired the
     20%, a majority of all the shares approve the transaction, all
     shareholders receive a minimum fair price for their shares, and certain
     other conditions are met.


                                       35
<PAGE>

   Alcoa's Articles of Incorporation also provide that Alcoa may not repurchase
any stock from an interested shareholder at prices greater than the current
fair market value. Under the PBCL, a person or group of persons acting in
concert who hold 20% of the shares of a registered corporation entitled to vote
in the election of directors constitutes a control group. On the occurrence of
the transaction that makes the group a control group, any other shareholder of
the registered corporation who objects can, under procedures set forth under
the PBCL, require the control group to purchase his or her shares at "fair
value," as defined in the PBCL.

   The PBCL also contains certain provisions applicable to a registered
corporation such as Alcoa which, under certain circumstances, permit a
corporation to:

  .  redeem "control shares," as defined in the PBCL;

  .  remove the voting rights of control shares; and

  .  require the disgorgement of profits by a "controlling person," as
     defined in the PBCL.

   The transfer agent and registrar for Alcoa common stock is First Chicago
Trust Company, a Division of EquiServe.

         DESCRIPTION OF TRUST PREFERRED SECURITIES AND TRUST GUARANTEE

Trust Preferred Securities

   The Declaration under which the Alcoa Trust is organized will be replaced by
an amended and restated trust agreement which will authorize the trustees of
the Alcoa Trust to issue on behalf of the Alcoa Trust one series of trust
preferred securities and one series of trust common securities. The form of
trust agreement is filed with the SEC and incorporated by reference as an
exhibit to the registration statement of which this prospectus is a part. The
trust agreement will be subject to, and governed by, the Trust Indenture Act.
The trust preferred securities will be issued to the public under the
registration statement of which this prospectus is a part. The trust common
securities will be issued directly or indirectly to Alcoa. This summary of
certain terms of the trust preferred securities and the trust agreement is not
complete. For more information, you should refer to the full text of the trust
preferred securities and the trust agreement, including the definitions of
terms used and not defined in this prospectus or the related prospectus
supplement, and those made part of the trust agreement by the Trust Indenture
Act.

   The trust preferred securities will have the terms, including dividends,
redemption, voting, conversion, liquidation rights and such other preferred,
deferred or other special rights or such restrictions as set forth in the trust
agreement or made part of the trust agreement by the Trust Indenture Act. A
prospectus supplement will describe the specific terms of the trust preferred
securities the Alcoa Trust is offering, including:

  .  the distinctive designation of trust preferred securities;

  .  the number of trust preferred securities issued by the Alcoa Trust;

  .  the annual dividend rate, or method of determining the rate, for trust
     preferred securities and the date(s) upon which dividends will be
     payable;

  .  whether dividends on trust preferred securities will be cumulative, and,
     in the case of trust preferred securities having cumulative dividend
     rights, the date or dates or method of determining the date(s) from
     which dividends on trust preferred securities will be cumulative;

  .  the amount or amounts that will be paid out of the assets of the Alcoa
     Trust to the holders of trust preferred securities upon voluntary or
     involuntary dissolution, winding up or termination of the Alcoa Trust;

  .  any terms and conditions under which trust preferred securities may be
     converted into shares of capital stock of Alcoa, including the
     conversion price per share and any circumstances under which the
     conversion right will expire;

  .  any terms and conditions upon which the related series of the
     subordinated debt securities of Alcoa may be distributed to holders of
     trust preferred securities;

  .  any obligation of the Alcoa Trust to purchase or redeem trust preferred
     securities and the price(s) at which, the period(s) within which and the
     terms and conditions upon which trust preferred securities will be
     purchased or redeemed, in whole or in part, under that obligation;

  .  any voting rights of trust preferred securities in addition to those
     required by law, including the number of votes per trust preferred
     security and any requirement for the approval by the holders of trust
     preferred securities, as a condition to specified action or amendments
     to the trust agreement; and

  .  any other relevant rights, preferences, privileges, limitations or
     restrictions of trust preferred securities consistent with the trust
     agreement or with applicable law.

Under the trust agreement, the Property Trustee will own a series of
subordinated debt securities of Alcoa purchased by the Alcoa Trust for the
benefit of the holders of the trust preferred securities and the trust common
securities. The payment of dividends out of money held by the Alcoa Trust, and
payments upon redemption of trust preferred securities or liquidation of the
Alcoa Trust, will be guaranteed by Alcoa to the extent described under "Trust
Guarantee."

                                       37
<PAGE>

   Certain United States Federal income tax considerations applicable to an
investment in trust preferred securities will be described in the applicable
prospectus supplement.

   In connection with the issuance of trust preferred securities, the Alcoa
Trust will also issue one series of trust common securities. The trust
agreement will authorize the regular trustees of the Alcoa Trust to issue on
behalf of the Alcoa Trust one series of trust common securities having such
terms as will be set forth in the trust agreement, including:

  .  dividends;

  .  conversion;

  .  redemption;

  .  voting;

  .  liquidation rights; or

  .  such restrictions as may be set forth in the trust agreement.

Except as otherwise provided in the prospectus supplement, the terms of the
trust common securities will be substantially identical to the terms of the
trust preferred securities. The trust common securities will rank pari passu,
and payments will be made on the trust common securities pro rata with the
trust preferred securities, except that, upon an event of default under the
trust agreement, the rights of the holders of the trust common securities to
payment in respect of dividends and payments upon liquidation, redemption and
otherwise will be subordinated to the rights of the holders of the trust
preferred securities. Except in certain limited circumstances, the trust common
securities will also carry the right to vote and appoint, remove or replace any
of the trustees of the Alcoa Trust. All of the trust common securities will be
directly or indirectly owned by Alcoa.

   Alcoa and certain of its subsidiaries maintain deposit accounts and conduct
other banking transactions, including borrowings in the ordinary course of
business, with the Property Trustee.

Trust Guarantee

   Alcoa will execute and deliver a guarantee, concurrently with the issuance
by the Alcoa Trust of its trust preferred securities, for the benefit of the
holders from time to time of the trust preferred securities. The accompanying
prospectus supplement will describe any significant differences between the
actual terms of the trust guarantee and the summary below. The following
summary of the trust guarantee is not complete. For more information, you
should refer to the full text of the trust guarantee, including the definitions
of terms used and not defined in this prospectus or the related prospectus
supplement and those terms made a part of the trust guarantee by the Trust
Indenture Act. The form of trust guarantee is filed with the SEC and
incorporated by reference as an exhibit to the registration statement of which
this prospectus is a part.

 General

   Alcoa will irrevocably and unconditionally agree, to the extent set forth in
the trust guarantee, to pay in full to the holders of trust preferred
securities the trust guarantee payments, except to the extent paid by the Alcoa
Trust, as and when due, regardless of any defense, right of set-off or
counterclaim that the Alcoa Trust may have or assert. The following payments
with respect to the trust preferred securities, to the extent not paid by the
Alcoa Trust, will be subject to the trust guarantee, without duplication:

  .  any accrued and unpaid dividends that are required to be paid on the
     trust preferred securities, to the extent the Alcoa Trust has funds
     legally available therefor;

  .  the redemption price, including all accrued and unpaid dividends,
     payable out of funds legally available therefor, with respect to any
     trust preferred securities called for redemption by the Alcoa Trust; and

                                       38
<PAGE>

  .  upon a liquidation of the Alcoa Trust, other than in connection with the
     distribution of subordinated debt securities of Alcoa to the holders of
     the trust preferred securities or the redemption of all of the trust
     preferred securities issued by the Alcoa Trust, the lesser of:

    .  the aggregate of the liquidation amount and all accrued and unpaid
       dividends on the trust preferred securities to the date of payment;
       and

    .  the amount of assets of the Alcoa Trust remaining available for
       distribution to holders of trust preferred securities in liquidation
       of the Alcoa Trust.

Alcoa's obligation to make a trust guarantee payment may be satisfied by
Alcoa's direct payment of the required amounts to the holders of trust
preferred securities or by causing the Alcoa Trust to pay the amounts to the
holders.

 Covenants of Alcoa

   In the trust guarantee, Alcoa will covenant that, so long as any trust
preferred securities issued by the Alcoa Trust remain outstanding, if there has
occurred any event that would constitute an event of default under the trust
guarantee or the trust agreement, then:

  .  Alcoa will not declare or pay any dividend on, make any distributions
     with respect to, or redeem, purchase or make a liquidation payment with
     respect to, any of its common stock, other than:

    .  purchases or acquisitions of shares of common stock in connection
       with the satisfaction by Alcoa of its obligations under any employee
       benefit plan;

    .  as a result of a reclassification of Alcoa's common stock or the
       exchange or conversion of one class or series of Alcoa's common
       stock for another class or series of Alcoa's common stock;

    .  the purchase of fractional interests in shares of Alcoa's common
       stock under the conversion or exchange provisions of such common
       stock or the security being converted or exchanged; or

    .  purchases or acquisitions of shares of common stock to be used in
       connection with acquisitions of common stock by shareholders under
       Alcoa's dividend reinvestment plan;

   or make any guarantee payments with respect to the foregoing; and

  .  Alcoa will not make any payment of principal of, or premium, if any, on
     or repurchase any debt securities issued by Alcoa (including guarantees)
     which rank pari passu with or junior to the subordinated debt
     securities, other than at stated maturity.

 Amendment and Assignment

   Except with respect to any changes that do not adversely affect the rights
of holders of trust preferred securities, in which case no vote will be
required, the trust guarantee may be amended only with the prior approval of
the holders of not less than a majority in liquidation amount of the
outstanding trust preferred securities. The manner of obtaining any approval of
the holders will be as set forth in an accompanying prospectus supplement. All
guarantees and agreements contained in the trust guarantee will bind the
successors, assigns, receivers, trustees and representatives of Alcoa and will
inure to the benefit of the holders of the trust preferred securities then
outstanding.

 Termination

   The trust guarantee will terminate:

  .  upon full payment of the redemption price of all trust preferred
     securities;


                                       39
<PAGE>

  .  upon distribution of the subordinated debt securities of Alcoa held by
     the Alcoa Trust to the holders of the trust preferred securities; or

  .  upon full payment of the amounts payable in accordance with the trust
     agreement upon liquidation of the Alcoa Trust.

The trust guarantee will continue to be effective or will be reinstated, as the
case may be, if at any time any holder of trust preferred securities must
restore payment of any sums paid under those trust preferred securities or the
trust guarantee. The subordination provisions of the subordinated debt
securities and the trust guarantee, respectively, will provide that in the
event payment is made on the subordinated debt securities or the trust
guarantee in contravention of the subordination provisions, such payments will
be paid over to the holders of Senior Debt.

 Ranking of the Trust Guarantee

   The trust guarantee will constitute an unsecured obligation of Alcoa and
will rank:

  .  subordinate and junior in right of payment to all other liabilities of
     Alcoa;

  .  pari passu with the most senior preferred or preference stock, if any,
     thereafter issued by Alcoa and with any guarantee thereafter entered
     into by Alcoa in respect of any preferred or preference stock or
     interests of any affiliate of Alcoa; and

  .  senior to Alcoa's common stock.

The trust agreement will provide that each holder of trust preferred securities
by acceptance of those securities agrees to the subordination provisions and
other terms of the trust guarantee.

   The trust guarantee will constitute a guarantee of payment and not of
collection. The trust guarantee will be deposited with the Property Trustee to
be held for the benefit of the trust preferred securities. The Property Trustee
will have the right to enforce the trust guarantee on behalf of the holders of
the trust preferred securities. The holders of not less than a majority in
aggregate liquidation amount of the trust preferred securities will have the
right to direct the time, method and place of conducting any proceeding for any
remedy available in respect of the trust guarantee, including the giving of
directions to the Property Trustee. Any holder of trust preferred securities
may institute a legal proceeding directly against Alcoa to enforce its rights
under the trust guarantee, without first instituting a legal proceeding against
the Alcoa Trust, or any other person or entity. The trust guarantee will not be
discharged except by payment of the trust guarantee payments in full to the
extent not paid by the Alcoa Trust, and by complete performance of all
obligations under the trust guarantee.

 Governing Law

   The trust guarantee will be governed by and construed in accordance with the
laws of the State of New York.

                                       40

                              PLAN OF DISTRIBUTION

   Alcoa and/or the Alcoa Trust may sell the securities in one or more of the
following ways:

  .  to underwriters for public offering and sale by them;

  .  directly to purchasers;

  .  through agents;

  .  through dealers; or

  .  through a combination of any of these methods of sale.

   Offers to purchase securities may be solicited directly by Alcoa and/or the
Alcoa Trust or by agents designated by Alcoa and/or the Alcoa Trust from time
to time. Any agent, who may be deemed to be an underwriter, as that term is
defined in the Securities Act, involved in the offer and sale of the securities
will be named, and any commissions payable by Alcoa and/or the Alcoa Trust to
that agent will be provided, in an applicable prospectus supplement. Alcoa
and/or the Alcoa Trust and its agents may sell the securities at:

  .  a fixed price or prices, which may be changed;

  .  market prices prevailing at the time of sale;

  .  prices related to such prevailing market prices; or

  .  negotiated prices.

   Underwriters, dealers and agents participating in the distribution of the
securities may be deemed to be underwriters, and any discounts and commissions
received by them and any profit realized by them on resale of the securities
may be deemed to be underwriting discounts and commissions under the Securities
Act. Underwriters, dealers and agents may be entitled, under agreements with
Alcoa and/or the Alcoa Trust, to indemnification against and contribution
toward certain civil liabilities, including liabilities under the Securities
Act, and to reimbursement by Alcoa and/or the Alcoa Trust for certain expenses.

   If an underwriter or underwriters are used in the offer or sale of
securities, Alcoa and/or the Alcoa Trust will execute an underwriting agreement
with the underwriters at the time of sale of the securities to the
underwriters, and the names of the underwriters and the principal terms of
Alcoa's and/or the Alcoa Trust's agreements with the underwriters will be
provided in the applicable prospectus supplement.

   If indicated in an applicable prospectus supplement, Alcoa and/or the Alcoa
Trust will authorize dealers acting as agents for Alcoa and/or the Alcoa Trust
to solicit offers by certain institutions to purchase securities from Alcoa
and/or the Alcoa Trust at the public offering price set forth in the prospectus
supplement under delayed delivery contracts providing for payment and delivery
on the date or dates stated in the prospectus supplement. The terms of such
delayed delivery contracts will be set forth in the applicable prospectus
supplement.

   Each underwriter, dealer and agent participating in the distribution of any
of the securities that are issuable in bearer form will agree that it will not
offer, sell or deliver, directly or indirectly, securities in bearer form in
the United States or to United States persons, other than qualifying financial
institutions, during the restricted period, as defined in United States
Treasury Regulations Section 1.163-5(c)(2)(i)(D)(7).

   All of the securities will be a new issue of securities with no established
trading market. Any underwriters to whom the securities are sold by Alcoa
and/or the Alcoa Trust for public offering and sale may make a market in the
securities, but such underwriters will not be obligated to do so and may
discontinue any market making at any time without notice. No assurance can be
given as to the liquidity of the secondary market for any of the securities.

Item 15. Indemnification of Directors and Officers.

Alcoa

   Article V of the By-Laws of Alcoa provides that Alcoa shall indemnify, under
specified circumstances, persons who were or are directors, officers or
employees of Alcoa or who served or serve other business entities at the
request of Alcoa. Under these By-Law provisions, a person who is wholly
successful in defending a claim will be indemnified for any reasonable
expenses. To the extent a person is not successful in defending a claim,
reasonable expenses of the defense and any liability incurred are to be
indemnified under these provisions only where independent legal counsel or
another disinterested person selected by the board of directors determines that
such person acted in good faith and in a manner such person reasonably believed
to be in, or not opposed to, the best interests of Alcoa, and in addition with
respect to any criminal action or proceeding, had no reasonable cause to
believe the conduct of such person was unlawful. Any expense incurred with
respect to any claim may be advanced by Alcoa if the recipient agrees to repay
such amount if it is ultimately determined that such recipient is not to be
indemnified pursuant to Article V.

   The foregoing By-Law provisions generally parallel Sections 1741 and 1745 of
the Pennsylvania Business Corporation Law ("PBCL"). Section 1746 and the By-
Laws both also provide that the indemnification provided for therein shall not
be deemed exclusive of any other rights to which those seeking indemnification
may otherwise be entitled.

   Section 1746 of the PBCL and the By-Laws provide for increased
indemnification protections for directors, officers and others. Indemnification
may be provided by Pennsylvania corporations in any case except where the act
or failure to act giving rise to the claim for indemnification is determined by
a court to have constituted willful misconduct or recklessness.

   Section 1713 of the PBCL also sets forth a framework whereby Pennsylvania
corporations, with the approval of the shareholders, may limit the personal
liability of directors for monetary damages except where the act or omission
giving rise to a claim constitutes self-dealing, willful misconduct or
recklessness. The section does not apply to a director's responsibility or
liability under a criminal or tax statute and may not apply to liability under
Federal statutes, such as the Federal securities laws.

   Alcoa's Articles of Incorporation and By-Laws were amended by the
shareholders to implement the increased protections made available to directors
under the PBCL as described in the preceding paragraph.

                                      II-1
<PAGE>

Article VIII of the By-Laws provides that, except as prohibited by law, every
director of Alcoa shall be entitled as of right to be indemnified by Alcoa for
expenses and any and all liability paid or incurred by such person by reason of
such person being or having been a director of Alcoa. Expenses incurred with
respect to any claim may be advanced by Alcoa, subject to certain exceptions.
The shareholders have also approved a form of indemnity agreement. Alcoa has
entered into such an indemnity agreement with each of its current directors.

   Alcoa has purchased a three-year liability insurance policy with an
aggregate limit of $150 million, with certain specified deductible amounts for
liability of directors and officers and reimbursement to Alcoa for
indemnification provided to directors and officers. The policy has an
expiration date of October 1, 2003 and provides liability insurance and
reimbursement coverage for Alcoa, and its directors and officers, which is
permitted by the laws of Pennsylvania referred to above.

   The Articles of Incorporation provide that except as prohibited by law,
Alcoa may indemnify any person who is or was a director, officer, employee or
agent of Alcoa or is or was serving at the request of Alcoa as a director,
officer, employee or agent of another corporation, partnership, joint venture,
trust or other enterprise, including, without limitation, any employee benefit
plan, and may take such steps as may be deemed appropriate by the board of
directors, including purchasing and maintaining insurance, entering into
contracts, including, without limitation, contracts of indemnification between
Alcoa and its directors and officers, creating a trust fund, granting security
interests or using other means, including, without limitation, a letter of
credit to ensure the payment of such amounts as may be necessary to effect such
indemnification. The By-Laws provide for indemnification of such persons to the
fullest extent permitted by law.

   The Articles of Incorporation also provide that to the fullest extent that
the laws of the Commonwealth of Pennsylvania permit elimination or limitation
of the liability of directors, no director of Alcoa shall be personally liable
for monetary damages for any action taken, or any failure to take any action.

   Section (6)(b) of the form of underwriting agreement relating to each of the
senior debt securities and the Class B Stock (Exhibit (1)(a) and (1)(b),
respectively, hereto) and Section 7(b) of the form of agency agreement (Exhibit
1(c) hereto) contain provisions relating to the indemnification by each
underwriter and agent, respectively, of Alcoa, officers and directors of Alcoa
and each person, if any, who controls Alcoa, and Section 6(a) of the form of
underwriting agreement relating to each of the senior debt securities and the
Class B Stock and Section 7(a) of such agency agreement contain provisions
relating to the indemnification by Alcoa of each underwriter and agent,
respectively, and each person controlling the same, against liabilities arising
out of any untrue statement of any material fact contained in this registration
statement, or omission therefrom of any material fact. In addition, Section
8(a) of the form of underwriting agreement relating to the trust preferred
securities (Exhibit (1)(d) hereto) contains provisions relating to the
indemnification by each underwriter of Alcoa and the Alcoa Trust, and Section
8(b) of the form of underwriting agreement relating to the trust preferred
securities contains provisions relating to the indemnification by Alcoa and the
Alcoa Trust of each underwriter, against liabilities arising out of any untrue
statement of any material fact contained in this registration statement, or
omission therefrom of any material fact.

The Alcoa Trust

   The trust agreement pursuant to which the Alcoa Trust is organized will
provide that no regular trustee, or affiliate of any regular trustee, or
officer, director, shareholder, member, partner, employee, representative or
agent of any trustee or of any such affiliate, or employee or agent of the
Alcoa Trust or its affiliates (each an "Indemnified Person") shall be liable,
responsible or accountable in damages or otherwise to the Alcoa Trust or any
employee or agent of the Alcoa Trust or its affiliates for any loss, damage or
claim incurred by reason of any act or omission performed or omitted by such
Indemnified Person in good faith on behalf of the Alcoa Trust and in a manner
such Indemnified Person reasonably believed to be within the scope of the
authority conferred on such Indemnified Person by such trust agreement or by
law, except that an Indemnified Person shall be liable for such loss, damage or
claim incurred by reason of such Indemnified Person's gross negligence

                                      II-2
<PAGE>

or willful misconduct with respect to such act or omission. The trust agreement
also provides that to the fullest extent permitted by applicable law, Alcoa
shall indemnify and hold harmless each Indemnified Person from and against any
loss, damage or claim incurred by such Indemnified Person by reason of any act
or omission performed or omitted by such Indemnified Person in good faith on
behalf of the Alcoa Trust and in a manner such Indemnified Person reasonably
believed to be within the scope of authority conferred on such Indemnified
Person by such trust agreement, except that no Indemnified Person shall be
entitled to be indemnified in respect of any loss, damage or claim incurred by
such Indemnified Person by reason of gross negligence or willful misconduct
with respect to such act or omission. The trust agreement further provides
that, to the fullest extent permitted by applicable law, expenses, including
legal fees, incurred by an Indemnified Person in defending any claim, demand,
action, suit or proceeding shall, from time to time, be advanced by Alcoa prior
to the final disposition of such claim, demand, action, suit or proceeding upon
receipt of an undertaking by or on behalf of the Indemnified Person to repay
such amount if it shall be determined that the Indemnified Person is not
entitled to be indemnified for the underlying cause of action as authorized by
such trust agreement.

Item 16. Exhibits.

   A list of Exhibits filed with this registration statement is contained on
the Exhibit Index and is incorporated herein by reference.

Item 17. Undertakings.

   The undersigned Registrants hereby undertake:

       (1) To file, during any period in which offers or sales are being
  made, a post-effective amendment to this registration statement:

         (i) To include any prospectus required by Section 10(a)(3) of the
    Securities Act of 1933, unless the information required to be included
    in such post-effective amendment is contained in a periodic report
    filed by Alcoa pursuant to Section 13 or Section 15(d) of the
    Securities Exchange Act of 1934 and incorporated herein by reference;

         (ii) To reflect in the prospectus any facts or events arising
    after the effective date of the registration statement (or the most
    recent post-effective amendment thereof) which, individually or in the
    aggregate, represent a fundamental change in the information set forth
    in the registration statement, unless such information required to be
    included in such post-effective amendment is contained in a periodic
    report filed by Alcoa pursuant to Section 13 or Section 15(d) of the
    Securities Exchange Act of 1934 and incorporated herein by reference;
    notwithstanding the foregoing, any increase or decrease in volume of
    securities offered (if the total dollar value of securities offered
    would not exceed that which was registered) and any deviation from the
    low or high end of the estimated maximum offering range may be
    reflected in the form of prospectus filed with the SEC pursuant to Rule
    424(b) if, in the aggregate, the changes in volume and price represent
    no more than a 20 percent change in the maximum aggregate offering
    price set forth in the "Calculation of Registration Fee" table in the
    effective registration statement; and

         (iii) To include any material information with respect to the plan
    of distribution not previously disclosed in the registration statement
    or any material change to such information in the registration
    statement;

                                      II-3
<PAGE>

       (2) That, for the purpose of determining any liability under the
  Securities Act of 1933, each such post-effective amendment shall be deemed
  to be a new registration statement relating to the securities offered
  therein, and the offering of such securities at that time shall be deemed
  to be the initial bona fide offering thereof.

       (3) To remove from registration by means of a post-effective amendment
  any of the securities being registered which remain unsold at the
  termination of the offering.

       (4) That, for purposes of determining any liability under the
  Securities Act of 1933, each filing of Alcoa's annual report pursuant to
  Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and,
  where applicable, each filing of an employee benefit plan's annual report
  pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is
  incorporated by reference in the registration statement shall be deemed to
  be a new registration statement relating to the securities offered therein,
  and the offering of such securities at that time shall be deemed to be the
  initial bona fide offering thereof.

       (5) That, for purposes of determining any liability under the
  Securities Act of 1933, the information omitted from the form of prospectus
  filed as part of this registration statement in reliance upon Rule 430A and
  contained in a form of prospectus filed by the Registrants pursuant to Rule
  424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be
  part of this registration statement as of the time it was declared
  effective.

       (6) For the purpose of determining any liability under the Securities
  Act of 1933, each post-effective amendment that contains a form of
  prospectus shall be deemed to be a new registration statement relating to
  the securities offered therein, and the offering of such securities at that
  time shall be deemed to be the initial bona fide offering thereof.

   Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Registrants pursuant to the foregoing provisions described in Item 15 above,
the Registrants have been informed that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrants of expenses incurred or paid by a director, officer or controlling
person of the Registrants in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, each Registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.

is or are delivered to the Trustee, and, where it is hereby expressly required,
to the Company. Such instrument or instruments (and the action embodied therein
and evidenced thereby) are herein sometimes referred to as the "Act" of the

certificate or affidavit shall also constitute sufficient proof of his
authority.

instrument or writing, or the authority of the Person executing the same, may
also be proved in any other manner which the Trustee deems sufficient and in

Register.

               (e) Any request, demand, authorization, direction, notice,

future Holder of the same Debenture and the Holder of every Debenture issued

of anything done or suffered to be done by the Trustee or the Company in
reliance thereon, whether or not notation of such action is made upon such
Debenture.

               (f) The Company may, but shall not be obligated to, fix a record
date for the purpose of determining the Holders entitled to take any action
under this Indenture by vote or consent. If a record date is fixed, those
Persons who

                                      18
<PAGE>

were Holders at such record date (or their duly designated proxies), and only

other document provided or permitted by this Indenture to be made upon, given or
furnished to, or filed with

               (a) the Trustee by any Holder or by the Company shall be
sufficient for every purpose hereunder if made, given, furnished or filed in
writing to or with the Trustee at its Corporate Trust Office, or

               (b) the Company by the Trustee or by any Holder shall be
sufficient for every purpose (except as otherwise provided in Section 5.1
hereof) hereunder if in writing and mailed, first class, postage prepaid, to the
Company addressed to it at the address of its principal office specified in the
first paragraph of this instrument or at any other address previously furnished

given (unless otherwise herein expressly provided) if in writing and mailed,
first class postage prepaid, to each Holder affected by such event, at the
address of such Holder as it appears in the Securities Register on the date such
notice is mailed, which shall be not later than the latest date, and not earlier
than the earliest date, prescribed for the giving of such notice.  In any case
where notice to Holders is given by mail, neither the failure to mail such
notice, nor any defect in any notice so mailed, to any particular Holder shall
affect the sufficiency of such notice with respect to other Holders.  Where this
Indenture provides for notice in any manner, such notice may be waived in
writing by the Person entitled to receive such notice, either before or after
the event, and such waiver shall be the equivalent of such notice.  Waivers of

                                      19
<PAGE>

notice by Holders shall be filed with the Trustee, but such filing shall not be
a condition precedent to the validity of any action taken in reliance upon such
waiver.

          In case by reason of the suspension of regular mail service or by
reason of any other cause it shall be impracticable to give such notice by mail,
then such notification as shall be made with the approval of the Trustee shall
constitute a sufficient notification for every purpose hereunder.

          Section 1.7    Conflict with Trust Indenture Act.  If any provision of
                         ---------------------------------
this Indenture limits, qualifies or conflicts with a provision of the Trust
Indenture Act that is required under such act to be a part of and govern this
Indenture, the latter provision shall control.  If any provision of this
Indenture modifies or excludes any provision of the Trust Indenture Act that may
be so modified or excluded, the former provision shall be deemed to apply.

any way be affected or impaired thereby.

          Section 2.3    Form of Reverse of Debenture.  This Debenture is one of
                         ----------------------------
a duly authorized issue of Debentures of the Company (herein called the
"Debentures") limited to the aggregate principal amount of $______________,
issued under an Indenture, dated as of _____ __, 20__ (herein called the
"Indenture"), between the Company and Chase Manhattan Trust Company, National
Association, as Trustee (herein called the "Trustee", which term includes any
successor trustee under the Indenture), to which Indenture and all indentures
supplemental thereto reference is hereby made for a statement of the respective
rights, limitations of rights, duties and immunities thereunder of the Trustee,
the Company and the Holders of the Debentures, and of the terms upon which the
Debentures are, and are to be, authenticated and delivered. All terms used in
this Debenture that are defined in the Indenture shall have the meanings
assigned to them in the Indenture.

          The amount of interest payable for any period will be computed on the
basis of a 360-day year of twelve 30-day months.  For periods less than a full
month, interest shall be computed on the actual number of elapsed days based on
a 360-day year.  In the event that any date on which interest is payable on this
Debenture is not a Business Day, then a payment of the interest on such date
will be made on the next succeeding day which is a Business Day (and without any
interest or other payment in respect of any such delay) with the same force and
effect as if made on the date the payment was originally payable.  A "Business
Day" shall mean any day other than a Saturday or a Sunday or a day on which
banking institutions in the

                                      23
<PAGE>

City of New York are authorized or required by law or executive order to remain
closed or a day on which the Corporate Trust Office of the Trustee[, or the
principal office of the Property Trustee under the Trust Agreement] is closed
for business. The interest installment so payable, and punctually paid or duly
provided for, on any Interest Payment Date will, as provided in the Indenture,
be paid to the Person in whose name this Debenture (or one or more Predecessor
Debentures, as defined in the Indenture) is registered at the close of business
on the Regular Record Date, for such interest installment which shall be the
date which is the fifteenth day (whether or not a Business Day) next preceding
such Interest Payment Date. Any such interest installment not so punctually paid
or duly provided for shall forthwith cease to be payable to the Holder on such
Regular Record Date and may either be paid to the Person in whose name this
Debenture (or one or more Predecessor Debentures) is registered at the close of
business on a Special Record Date for the payment of such Defaulted Interest to
be fixed by the Trustee, notice whereof shall be given to Holders of Debentures
not less than 10 days prior to such Special Record Date, or be paid at any time
in any other lawful manner not inconsistent with the requirements of any
securities exchange on which the Debentures may be listed, and upon such notice
as may be required by such exchange, all as more fully provided in the
Indenture.

          The Company shall have the right at any time during the term of this
Debenture, from time to time, to extend the interest payment period of such
Debenture for up to [20 consecutive quarters] with respect to each deferral
period (each such deferral period an "Extension Period"), during which periods
the Company shall have the right not to make payments of interest on any
Interest Payment Date, and at the end of which the Company shall pay all
interest then accrued and unpaid (together with Additional Interest, if any,
thereon to the extent permitted by applicable law); provided that during any
such Extension Period, the Company shall not (a) declare or pay any dividend on,
make distributions with respect to, or redeem, purchase or make a liquidation
payment with respect to, any of its Common Stock (other than (i) purchases or
acquisitions of shares of Common Stock in connection with the satisfaction by
the Company of its obligations under any employee benefit plan, (ii) as a result
of a reclassification of the Company's Common Stock or the exchange or
conversion of one class or series of the Company's Common Stock for another
class or series of the Company's Common Stock, (iii) the purchase of fractional
interests in shares of the Company's Common Stock pursuant to the conversion or
exchange provisions of such Common Stock of the Company or the security being
converted or exchanged or (iv) purchases or acquisitions of shares of Common
Stock to be used in connection with acquisitions of Common Stock by

                                      24
<PAGE>

shareholders pursuant to the Company's dividend reinvestment plan) or make any
guarantee payments with respect to the foregoing and (b) the Company shall not
make any payment of principal or premium, if any, on or repurchase any debt
securities (including guarantees) other than at stated maturity issued by the
Company which rank pari passu with or junior to the Debentures. Prior to the
termination of any such Extension Period, the Company may further extend the
interest payment period, provided that no Extension Period shall exceed [20
consecutive quarters] or extend beyond the Stated Maturity of the Debenture.
Upon the termination of any such Extension Period and upon the payment of all
accrued and unpaid interest and any Additional Interest then due, the Company
may elect to begin a new Extension Period, subject to the above requirements. No
interest shall be due and payable during an Extension Period except at the end
thereof. The Company shall give the Trustee, [the Property Trustee and the
Administrative Trustees (as defined in the Trust Agreement)] notice of its
selection of an Extension Period at least one Business Day prior to [the earlier
of (i) the record date for the date the distributions on the Preferred
Securities (or if no Preferred Securities are outstanding, for] the date
interest on the Debentures) would have been payable except for the election to
begin such Extension Period and (ii) the date [the Property Trustee (or if no
Preferred Securities are outstanding,] the Debenture Trustee) is required to
give notice to the NYSE or other applicable self-regulatory organizations [or to
holders of [such Preferred Securities (or, if no Preferred Securities are
outstanding, to the holders of] such Debentures) of the record date.

          Payment of the principal of (and premium, if any) and interest on this
Debenture will be made [if a Global Security is issued - to The Depository
Trust Company or its nominee] [if securities in definitive form are issued - at
the office or agency of the Paying Agent maintained for that purpose in the
United States], in such coin or currency of the United States of America as at
the time of payment is legal tender for payment of public and private debts
provided, however, that at the option of the Company payment of interest may be
made (i) by check mailed to the address of the Person entitled thereto as such
address shall appear in the Securities Register or (ii) by wire transfer in
immediately available funds at such place and to such account as may be
designated by the Person entitled thereto as specified in the Securities
Register.

          The indebtedness evidenced by this Debenture is, to the extent
provided in the Indenture, subordinate and subject in right of payments to the
prior payment in full of all Senior Debt (as defined in the Indenture), and this
Debenture is issued subject to the provisions of the Indenture with respect
thereto.  Each Holder of this Debenture, by accepting the same, (a) agrees to
and shall be bound by such provisions, (b) authorizes and directs the Trustee on
his behalf to take such actions as

                                      25
<PAGE>

may be necessary or appropriate to effectuate the subordination so provided and
(c) appoints the Trustee his attorney-in-fact for any and all such purposes.
Each Holder hereof, by his acceptance hereof, waives all notice of the
acceptance of the subordination provisions contained herein and in the Indenture
by each holder of Senior Debt, whether now outstanding or hereafter incurred,
and waives reliance by each such holder upon said provisions.

          At any time on or after _________, 20__, the Company may, at its
option, subject to the terms and conditions of Article 11 of the Indenture,
redeem this Debenture in whole at any time or in part from time to time, at the
Redemption Prices set forth in Section 11.8 of the Indenture.

          In the event of redemption of this Debenture in part only, a new
Debenture or Debentures for the unredeemed portion hereof will be issued in the
name of the Holder hereof upon the cancellation hereof.

          [If a Special Event shall occur and be continuing, this Debenture
shall be exchangeable for Preferred Securities in accordance with Section 11.9
of the Indenture or, in certain circumstances, redeemable by the Company in
accordance with Section 11.8 of the Indenture.]

         [Subject to the terms and conditions set forth in Article 13 of the
Indenture, this Debenture is convertible, at the option of the Holder hereof,
into shares of Common Stock.]

          If an Event of Default shall occur and be continuing, the principal of
the Debentures may be declared due and payable in the manner, with the effect
and subject to the conditions provided in the Indenture.

          The Indenture contains provisions for satisfaction, discharge and
defeasance of the entire indebtedness of this Debenture upon compliance by the
Company with certain conditions set forth in the Indenture.

          The Indenture permits, with certain exceptions as therein provided,
the amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Debentures to be affected under the
Indenture at any time by the Company and the Trustee with the consent of the
Holders of a majority in principal amount of the Debentures.  The Indenture also
contains provisions permitting Holders of specified percentages in principal
amount

                                      26
<PAGE>

of the Debentures at the time Outstanding, on behalf of the Holders of all
Debentures, to waive compliance by the Company with certain provisions of the
Indenture and certain past defaults under the Indenture and their consequences.
Any such consent or waiver shall be conclusive and binding upon the Holder of
this Debenture and upon all future Holders of this Debenture and of any
Debenture issued upon the registration of transfer hereof or in exchange
therefor or in lieu hereof, whether or not notation of such consent or waiver is
made upon this Debenture.

          As provided in and subject to the provisions of the Indenture, if an
Event of Default occurs and is continuing, then and in every such case the
Trustee or the Holders of not less than 25% in principal amount of the
Outstanding Debentures may declare the principal amount of all the Debentures to
be due and payable immediately, by a notice in writing to the Company (and to
the Trustee if given by Holders); [provided that, if upon an Event of Default,
the Trustee or the Holders of not less than 25% in principal amount of the
Outstanding Debentures fail to declare the principal of all the Debentures to be
immediately due and payable, the holders of at least 25% in aggregate
liquidation amount of the Preferred Securities then out standing shall have such
right by a notice in writing to the Company and the Trustee,] and upon any such
declaration such principal amount (or specified amount) of and the accrued
interest (including any Additional Interest) on all the Debentures shall become
immediately due and payable, provided that the payment of principal and interest
(including any Additional Interest) on such Debentures shall remain subordinated
to the extent provided in Article 12 of the Indenture.

          No reference herein to the Indenture and no provision of this
Debenture or of the Indenture shall alter or impair the obligation of the
Company, which is absolute and unconditional, to pay the principal of (and
premium, if any) and interest on this Debenture at the times, place and rate,
and in the coin or currency, herein prescribed.

          As provided in the Indenture and subject to certain limitations
therein set forth, the transfer of this Debenture is registrable in the
Securities Register, upon surrender of this Debenture for registration of
transfer at the Company Office duly endorsed by, or accompanied by a written
instrument of transfer in form satisfactory to the Company and the Securities
Registrar duly executed by, the Holder hereof or his attorney duly authorized in
writing, and thereupon one or more new Debentures, of authorized denominations
and for the same aggregate principal amount, will be issued to the designated
transferee or transferees.  No service charge shall be made for any such
registration of transfer or exchange, but the Company may require

                                      27
<PAGE>

payment of a sum sufficient to cover any tax or other governmental charge
payable in connection therewith.

          Prior to due presentment of this Debenture for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name this Debenture is registered as the owner
hereof for all purposes, whether or not this Debenture be overdue, and neither
the Company, the Trustee nor any such agent shall be affected by notice to the
contrary.

          The Debentures are issuable only in registered form without coupons in
denominations of $[1,000] and any integral multiple thereof. As provided in the
Indenture and subject to certain limitations therein set forth, Debentures are
exchangeable for a like aggregate principal amount of Debentures of a different
authorized denomination, as requested by the Holder surrendering the same.

          The Company and, by its acceptance of this Debenture or a beneficial
interest therein, the Holder of, and any Person that acquires a beneficial
interest in, this Debenture agree that for United States Federal, state and
local tax purposes it is intended that this Debenture constitute indebtedness.

          THE INDENTURE AND THIS DEBENTURE SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO CONFLICTS OF
LAW PRINCIPLES THEREOF.

          Section 3.3  Execution, Authentication, Delivery and Dating.  The
                       ----------------------------------------------
Debentures shall be executed on behalf of the Company by a duly authorized
officer on behalf of the Company, whose signature shall be certified by the
Company's Secretary or one of its Assistant Secretaries.  The signature of any
of these officers on the Debentures may be manual or facsimile.

          Debentures bearing the manual or facsimile signatures of individuals
who were at any time the proper officers of the Company shall bind the Company,
notwithstanding that such individuals or any of them have ceased to hold such
offices prior to the authentication and delivery of such Debentures or did not

authenticated on original issuance from time to time and delivered pursuant to

delivery pursuant to oral instructions of the Company or a duly authorized
agent, which instructions shall be promptly confirmed in writing.

          Each Debenture shall be dated the date of its authentication.

be valid or obligatory for any purpose, unless there appears on such Debenture a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by the manual signature of one of its authorized

denomination, substantially of the tenor of the definitive Debentures in lieu
of which they are issued and with such appropriate insertions, omissions,
substitutions and other variations as the officers executing such Debentures may
determine, as evidenced by their execution of such Debentures.

          If temporary Debentures are issued, the Company will cause
definitive Debentures to be prepared without unreasonable delay. After the
preparation of definitive Debentures, the temporary Debentures shall be
exchangeable for definitive Debentures upon surrender of the temporary
Debentures at the office or agency of the Company designated for the purpose
without charge to the Holder. Upon surrender for cancellation of any one or more
temporary Debentures, the Company shall execute and the Trustee shall
authenticate and deliver in exchange therefor a like aggregate principal amount
of definitive Debentures of authorized denominations. Until so exchanged, the
temporary Debentures shall in all respects be entitled to the same benefits
under this Indenture as definitive Debentures.

appointed "Securities Registrar" for the purpose of registering Debentures and
transfers of Debentures as herein provided.

          Upon surrender for registration of transfer of any Debenture at the
office or agency of the Company designated for that purpose the Company shall
execute, and the Trustee shall authenticate and deliver, in the name of the
designated transferee or transferees, one or more new Debentures of any
authorized denominations, of a like aggregate principal amount.

          At the option of the Holder, Debentures may be exchanged for other
Debentures of any authorized denominations, of a like aggregate principal
amount, upon surrender of the Debentures to be exchanged at such office or
agency.  Whenever any Debentures are so surrendered for exchange, the Company
shall execute, and the Trustee shall authenticate and deliver, the Debentures
which the Holder making the exchange is entitled to receive.

          All Debentures issued upon any registration of transfer or exchange of
Debentures shall be the valid obligations of the Company, evidencing the same
debt, and entitled to the same benefits under this Indenture, as the Debentures
surrendered upon such registration of transfer or exchange.

          Every Debenture presented or surrendered for registration of transfer
or exchange shall (if so required by the Company or the Securities Registrar) be
duly endorsed, or be accompanied by a written instrument of transfer in form
satisfactory to the Company and the Securities Registrar, duly executed by the
Holder thereof or his attorney duly authorized in writing.

          No service charge shall be made to a Holder for any transfer or
exchange of Debentures, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
with any transfer or exchange of Debentures.

          Notwithstanding any of the foregoing, any Global Security shall be
exchangeable pursuant to this Section 3.5 for Debentures registered in the names
of Persons other than the Depositary for such Debenture or its nominee only if
(a) such Depositary notifies the Company that it is unwilling or unable to
continue as Depositary for any Global Security and the Company shall not have
appointed a successor depositary within 90 days after such notice, or if at any
time such Depositary ceases

                                      34
<PAGE>

to be a clearing agency registered under the Securities Exchange Act of 1934, as
amended, (b) the Company executes and delivers to the Trustee a Company Order
that any Global Security shall be so exchangeable or (c) there shall have
occurred and be continuing an Event of Default. Any Global Security shall be
exchangeable for Debentures registered in such names as such Depositary shall
direct.

          Notwithstanding any other provisions in this Indenture, a Global
Security may not be transferred except as a whole by the Depositary with respect
to a Global Security to a nominee of such Depositary or by a nominee of such
Depositary to such Depositary or another nominee of such Depositary.

          Neither the Company nor the Trustee shall be required, pursuant to the
provisions of this Section, (a) to issue, register the transfer of or exchange
any Debenture during a period beginning at the opening of business 15 days
before the day of selection for redemption of Debentures pursuant to Article 11
and ending at the close of business on the day of mailing of notice of
redemption or (b) to register the transfer of or exchange any Debenture so
selected for redemption in whole or in part, except, in the case of any
Debenture to be redeemed in part, any portion thereof not to be redeemed.

          Section 3.6  Mutilated, Destroyed, Lost and Stolen Debentures.  If any
                       ------------------------------------------------
mutilated Debenture is surrendered to the Trustee together with such security or
indemnity as may be required by the Company or the Trustee to save each of them
harmless, the Company shall execute and the Trustee shall authenticate and
deliver in exchange therefor a new Debenture and bearing a number not
contemporaneously outstanding.

          If there shall be delivered to the Company and to the Trustee (a)
evidence to their satisfaction of the destruction, loss or theft of any
Debenture, and (b) such security or indemnity as may be required by them to save
each of them harmless, then, in the absence of actual notice to the Company or
the Trustee that such Debenture has been acquired by a bona fide purchaser, the
Company shall execute and upon a Company Order the Trustee shall authenticate
and deliver, in lieu of any such destroyed, lost or stolen Debenture, a new
Debenture bearing a number not contemporaneously outstanding.

          In case any such mutilated, destroyed, lost or stolen Debenture has
become or is about to become due and payable, the Company in its discretion may,
instead of issuing a new Debenture, pay such Debenture.

                                      35
<PAGE>

          Upon the issuance of any new Debenture under this Section, the Company
may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith.

          Every new Debenture issued pursuant to this Section in lieu of any
destroyed, lost or stolen Debenture shall constitute an original additional
contractual obligation of the Company, whether or not the destroyed, lost or
stolen Debenture shall be at any time enforceable by anyone, and shall be
entitled to all the benefits of this Indenture equally and proportionately with
any and all other Debentures duly issued hereunder.

          The provisions of this Section are exclusive and shall preclude (to
the extent lawful) all other rights and remedies with respect to the replacement
or payment of mutilated, destroyed, lost or stolen Debentures.

          Section 3.7  Payment of Interest; Interest Rights Preserved.  Interest
                       ----------------------------------------------
on any Debenture which is payable, and is punctually paid or duly provided for,
on any Interest Payment Date, shall be paid to the Person in whose name that
Debenture (or one or more Predecessor Debentures) is registered at the close of
business on the Regular Record Date, except that interest payable on the Stated
Maturity of the Debentures shall be paid to the Person to whom principal is
paid.

          Any interest on the Debentures which is payable, but is not timely
paid or duly provided for, on an Interest Payment Date (herein called "Defaulted
Interest"), shall forthwith cease to be payable to the registered Holder on the
Regular Record Date by virtue of having been such Holder, and such Defaulted
Interest may be paid by the Company, at its election in each case, as provided
in clause (a) or (b) below:

                (a) The Company may elect to make payment of any Defaulted
Interest to the Persons in whose names the Debentures (or their respective
Predecessor Debentures) are registered at the close of business on a Special
Record Date for the payment of such Defaulted Interest, which shall be fixed in
the following manner. The Company shall notify the Trustee in writing of the
amount of Defaulted Interest proposed to be paid on the Debentures and the date
of the proposed payment, and at the same time the Company shall deposit with the
Trustee an amount of money equal to the aggregate amount proposed to be paid in
respect of such Defaulted Interest or shall make arrangements satisfactory to
the Trustee for

                                      36
<PAGE>

such deposit prior to the date of the proposed payment, such money when
deposited to be held in trust for the benefit of the Persons entitled to such
Defaulted Interest as in this Clause provided. Thereupon the Trustee shall fix a
Special Record Date for the payment of such Defaulted Interest which shall be
not more than 15 days and not less than 10 days prior to the date of the
proposed payment and not less than 10 days after the receipt by the Trustee of
the notice of the proposed payment. The Trustee shall promptly notify the
Company of such Special Record Date and, in the name and at the expense of the
Company, shall cause notice of the proposed payment of such Defaulted Interest
and the Special Record Date therefor to be mailed, first class, postage prepaid,
to each Holder of the Debentures at the address of such Holder as it appears in
the Securities Register not less than 10 days prior to such Special Record Date.
Notice of the proposed payment of such Defaulted Interest and the Special Record
Date therefor having been mailed as aforesaid, such Defaulted Interest shall be
paid to the Persons in whose names the Debentures (or their respective
Predecessor Debentures) are registered on such Special Record Date and shall no
longer be payable pursuant to the following clause (b).

                  (b)  The Company may make payment of any Defaulted Interest in
any other lawful manner not inconsistent with the requirements of any securities
exchange on which the Debentures may be listed and, upon such notice as may be
required by such exchange (or by the Trustee if the Debentures are not listed),
if, after notice given by the Company to the Trustee of the proposed payment
pursuant to this Clause, such payment shall be deemed practicable by the
Trustee.

          Subject to the foregoing provisions of this Section, each Debenture
delivered under this Indenture upon registration of transfer of or in exchange
for or in lieu of any other Debenture shall carry the rights to interest accrued
and unpaid, and to accrue, which were carried by such other Debenture.

          Section 3.8  Persons Deemed Owners.  The Company, the Trustee, the
                       ---------------------
Paying Agent and any agent of the Company or the Trustee or the Paying Agent may
treat the Person in whose name any Debenture is registered as the owner of such
Debenture for the purpose of receiving payment of principal of and (subject to
Section 3.7) interest on such Debenture and for all other purposes whatsoever,
whether or not such Debenture be overdue, and neither the Company, the Trustee
nor any agent of the Company or the Trustee shall be affected by notice to the
contrary.

          Section 3.9  Cancellation.  All Debentures surrendered for payment,
                       ------------
redemption, conversion, registration of transfer or exchange shall, if
surrendered to any Person other

                                      37
<PAGE>

than the Trustee, be delivered to the Trustee, and any such Debentures and
Debentures surrendered directly to the Trustee for any such purpose shall be
promptly canceled by it. The Company may at any time deliver or cause to be
delivered to the Trustee for cancellation any Debentures previously
authenticated and delivered hereunder which the Company may have acquired in any
manner whatsoever, and all Debentures so delivered shall be promptly canceled by
the Trustee. No Debentures shall be authenticated in lieu of or in exchange for
any Debentures canceled as provided in this Section, except as expressly
permitted by this Indenture. All canceled Debentures shall be destroyed by the
Trustee and upon request, the Trustee shall deliver to the Company a certificate
of such destruction.

          Section 3.10  Computation of Interest.  Interest on the Debentures
                        -----------------------
shall be computed on the basis of a 360-day year of twelve 30-day months.

          Section 3.11  Deferrals of Interest Payment Dates.  The Company shall
                        -----------------------------------
have the right, at any time during the term of the Debentures, from time to time
to extend the interest payment period for the Debentures for up to [20
consecutive quarters] with respect to each deferral period (each, an "Extension
Period") during which periods the Company shall have the right to not make
payments of interest on any Interest Payment Date, and at the end of such
Extension Period the Company shall pay all interest then accrued and unpaid
thereon (together with Additional Interest thereon, if any, at the rate
specified for the Debentures to the extent permitted by applicable law),
provided, however, that during any such Extension Period, the Company shall not
(a) declare or pay any dividend on, make distributions with respect to, or
redeem, purchase or make a liquidation payment with respect to, any of its
Common Stock (other than (i) purchases or acquisitions of shares of Common Stock
in connection with the satisfaction by the Company of its obligations under any
employee benefit plan, (ii) as a result of a reclassification of the Company's
Common Stock or the exchange or conversion of one class or series of the
Company's Common Stock for another class or series of the Company's Common
Stock, (iii) the purchase of fractional interests in shares of the Company's
Common Stock pursuant to the conversion or exchange provisions of such Common
Stock of the Company or the security being converted or exchanged or (iv)
purchases or acquisitions of shares of Common Stock to be used in connection
with acquisitions of Common Stock by shareholders pursuant to the Company's
dividend reinvestment plan) or make any guarantee payments with respect to the
foregoing and (b) the Company shall not make any payment of principal or
premium, if any, on or repurchase any debt securities (including guarantees)
other than at stated maturity issued by the Company which rank pari passu with

                                      38
<PAGE>

or junior to the Debentures. Prior to the termination of any such Extension
Period, the Company may further extend the interest payment period, provided
that no Extension Period shall exceed [20 consecutive quarters] or extend beyond
the Stated Maturity of the Debentures. Upon the termination of any such
Extension Period and upon the payment of all accrued and unpaid interest and any
Additional Interest then due, the Company may elect to begin a new Extension
Period, subject to the above requirements. No interest shall be due and payable
during an Extension Period except at the end thereof. The Company shall give the
Trustee[, the Property Trustee and the Administrative Trustees (as defined in
the Trust Agreement)] notice of its selection of an Extension Period at least
one Business Day prior to the earlier of (i) the record date for the date [the
distributions on the Preferred Securities (or if no Preferred Securities are
outstanding, for the date] interest on the Debentures[)] would have been payable
except for the election to begin such Extension Period and (ii) the date the
[Property Trustee (or if no Preferred Securities are outstanding, the Debenture]
Trustee[)] is required to give notice to the NYSE or other applicable self-
regulatory organizations or[ to holders of such Preferred Securities (or, if no
Preferred Securities are outstanding,] to the holders of such Debentures[)] of
the record date. Such notice shall specify the period selected.

          The Company, or the Trustee at the request of the Company, shall
promptly give notice of the Company's selection of such Extension Period to the
Holders of the outstanding Debentures.

          Section 3.12  Right of Set-off.  Notwithstanding anything to the
                        ----------------
contrary in the Indenture, the Company shall have the right to set-off any
payment it is otherwise required to make thereunder in respect of the Debentures
to the extent the Company has theretofore made, or is concurrently on the date
of such payment making, a payment relating to the Debentures under the
Guarantee.

          Section 3.13  Agreed Tax Treatment.  Each Debenture issued hereunder
                        --------------------
shall provide that the Company and, by its acceptance of a Debenture or a
beneficial interest therein, the Holder of, and any Person that acquires a
beneficial interest in, such Debenture agree that for United States Federal,
state and local tax purposes it is intended that such Debenture constitute
indebtedness.

          Section 3.14  CUSIP Numbers.  The Company in issuing the Debentures
                        -------------
may use "CUSIP" numbers (if then generally in use), and, if so, the Trustee
shall use such "CUSIP" number in notices of redemption as a convenience to
Holders; provided that any such notice may state that no representation is made
as to the correctness of such number either as printed on the Debentures or as
contained in

                                      39
<PAGE>

any notice of a redemption and that reliance may be placed only on the other
identification numbers printed on the Debentures, and any such redemption shall
not be affected by any defect in or omission of such numbers.

          Section 3.15  Global Security.  [(a)  In connection with any
                        ---------------
distribution of Debentures to holders of the Preferred Securities in connection
with the involuntary or voluntary dissolution, winding up or liquidation of the
Trust,

                        (i)  the Debentures in certificated form may be
     presented to the Trustee by the Property Trustee in exchange for one or
     more global certificates in an aggregate principal amount equal to the
     aggregate principal amount of all outstanding Debentures (each a "Global
     Security"), to be registered in the name of the Depositary, or its nominee,
     and delivered by the Trustee to the Depositary, or its custodian, for
     crediting to the accounts of its participants pursuant to the procedures of
     the Depositary. The Company upon any such presentation shall execute a
     Global Security in such aggregate principal amount and deliver the same to
     the Trustee for authentication and delivery in accordance with this
     Indenture; and

                        (ii) if any Preferred Securities are held in non book-
     entry certificated form, the Debentures in certificated form may be
     presented to the Trustee by the Property Trustee and any Preferred Security
     certificate which represents Preferred Securities other than Preferred
     Securities held by the Depositary or its nominee ("Non Book-Entry Preferred
     Securities") will be deemed to represent beneficial interests in Debentures
     presented to the Trustee by the Property Trustee having an aggregate
     principal amount equal to the aggregate liquidation amount of the Non Book-
     Entry Preferred Securities until such Preferred Security certificates are
     presented to the Securities Registrar for registration of transfer or
     reissuance at which time such Non-Book Entry Preferred Security
     certificates will be canceled and a Debenture, registered in the name of
     the holder of the Preferred Security certificate or the transferee of the
     holder of such Preferred Security certificate, as the case may be, with an
     aggregate principal amount equal to the aggregate liquidation amount of the
     Preferred Security certificate canceled, will be executed by the Company
     and delivered to the Trustee for authentication and delivery in accordance
     with this Indenture. On issue of such Debentures, Debentures with an
     equivalent aggregate principal amount that were presented by the Property
     Trustee to the Trustee will be deemed to have been canceled.]

<PAGE>

               (b) A Global Security may be transferred, in whole but not in
part, only to another nominee of the Depositary, or to a nominee of such
successor Depositary.

               (c) If (i) the Depositary notifies the Company that it is
unwilling or unable to continue as a depositary for such Global Security and no
successor depositary shall have been appointed within 90 days by the Company,
(ii) the Depositary, at any time, ceases to be a clearing agency registered
under the Exchange Act at which time the Depositary is required to be so
registered to act as such depositary and no successor depositary shall have been
appointed within 90 days by the Company, (iii) the Company, in its sole
discretion, determines that such Global Security shall be so exchangeable or
(iv) there shall have occurred an Event of Default with respect to such
Debentures, as the case may be, the Company will execute, and, subject to
Article 3 of this Indenture, the Trustee, upon written notice from the Company
and receipt of a Company Order, will authenticate and deliver the Debentures in
definitive registered form without coupons, in authorized denominations, and in
an aggregate principal amount equal to the principal amount of the Global
Security in exchange for such Global Security. In addition, upon an Event of
Default or if the Company may at any time determine that the Debenture shall no
longer be represented by a Global Security, in such event the Company will
execute, and subject to Section 3.5 of this Indenture, the Trustee, upon receipt
of an Officers' Certificate evidencing such determination by the Company and a
Company Order, will authenticate and make available for delivery the Debentures
in definitive registered form without coupons, in authorized denominations, and
in an aggregate principal amount equal to the principal amount of the Global
Security in exchange for such Global Security. Upon the exchange of the Global
Security for such Debentures in definitive registered form without coupons, in
authorized denominations, the Global Security shall be canceled by the Trustee.
Such Debentures in definitive registered form issued in exchange for the Global
Security shall be registered in such names and in such authorized denominations
as the Depositary, pursuant to instructions from its direct or indirect
participants or otherwise, shall instruct the Trustee. The Trustee shall deliver
such Debentures to the Depositary for delivery to the Persons in whose names
such Debentures are so registered.

Counsel to the effect that (i) if such deposits shall include Government
Obligations in respect of any government other than the United States of
America, such deposit shall not result in the Company, the Trustee or such trust
constituting an 'investment company' under the Investment Company Act of 1940,
as amended, and (ii) if any such deposit occurs more than one year prior to the
stated maturity or redemption date of the Debentures, the Holders will not
recognize income, gain or loss for Federal income tax purposes as a result of
such deposit, defeasance and discharge and will be subject to Federal income tax

and Article Ten [(except with respect to maintenance of the Trust as a grantor
trust for Federal Income Tax purposes under Section 10.8)] with respect to the

with respect to the Outstanding Debentures, the Company may omit to comply with
and shall have no liability in respect of any term, condition or limitation set
forth in Article Ten, whether directly or indirectly by reason of any reference
elsewhere herein to such Article by reason of any reference in such Article to
any other provi  sion herein or by reason of any reference to such Article in
any other document, and such omission to comply shall not constitute an Event of
Default under Section 5.1. The following shall be the conditions to application
of this paragraph (C):

               (a)  the Company shall have irrevocably deposited or caused to be
irrevocably deposited with the Trustee as a trust fund specifically pledged as
security for, and dedicated solely to, the benefit of the Holders of the
Debentures, (i) money in an amount, or (ii) Government Obligations, maturing as
to principal and interest at such times and in such amounts as will ensure the
availabil ity of money, or (iii) a combination thereof, sufficient in the
opinion of a nationally recognized firm of independent public accountants
expressed in a written certifica tion thereof delivered to the Trustee, to pay
(A) the principal and interest, if any, on all Debentures on each date that such
principal or interest, if any, is due and payable and (B) any mandatory sinking
fund or analogous payments on the dates on which such payments are due and
payable in accordance with the terms of this Indenture and the Debentures;

               (b)  no Event of Default or event which, with notice or lapse of
time or both, would become an Event of Default shall have occurred and be
continuing on the date of such deposit or at any time during the period ending
on the 123rd day after the date of such deposit (it being understood that this
condition shall not be deemed satisfied until the expiration of such period);

               (c)  such covenant defeasance shall not result in a breach or
violation of, or constitute of a default under, this Indenture or any other
material agreement or instrument to which the Company is a party or by which it
is bound;

               (d)  the Company shall have delivered to the Trustee an Opinion
of Counsel to the effect that (i) if such deposits shall include Government
Obligations in respect of any government other than the United States of
America, such deposit shall not result in the Company, the Trustee or such trust
constituting an 'investment company' under the Investment Company Act of 1940,
as amended, and (ii) the Holders will not recognize income, gain or loss for
Federal income tax purposes as a result of such covenant defeasance and will be
subject to federal income tax on the same amounts, in the same manner and at the
same times as would have been the case if such covenant defeasance had not
occurred; and

               (e)  the Company shall have delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that all conditions
precedent herein provided for relating to such covenant defeasance have been
complied with.

in respect of Government Obligations deposited with the Trustee, pursuant to
Section 4.1 shall be held in trust and applied by it to the payment, either

the Company, mail by first class mail to Holders of Debentures at their
addresses as they shall appear on the Securities Register for the Debentures,
notice that such moneys remain and that, after a date specified therein, which
shall not be less than 30 days from the date of such mailing any unclaimed

                       --------------------------------------------------
an Event of Default occurs and is continuing, then and in every such case the
Trustee or the Holders of not less than 25% in principal amount of the
Outstanding Debentures of any series may declare the principal amount of all the
Debentures of such series to be due and payable immediately, by a notice in
writing to the Company (and to the Trustee if given by Holders); [provided that,
if upon an Event of Default, the Trustee or the Holders of not less than 25% in
principal amount of the Outstanding Debentures fail to declare the principal of
all the Debentures to be immediately due and payable, the holders of at least
25% in aggregate liquidation amount of the Preferred Securities then outstanding
shall have such right by a notice in writing to the Company and the Trustee,]
and upon any such declaration such principal amount (or specified amount) of and
the accrued interest (including any Additional Interest) on all the Debentures
shall become immediately due and payable, provided that the payment of principal
and interest (including any Additional Interest) on the Debentures shall remain
subordinated to the extent provided in Article 12.

                                      47
<PAGE>

          At any time after such a declaration of acceleration with respect to
Debentures has been made and before a judgment or decree for payment of the
money due has been obtained by the Trustee as hereinafter in this Article
provided, the Holders of a majority in principal amount of the Outstanding
Debentures, by written notice to the Company and the Trustee may rescind and
annul such declaration and its consequences if:

               (i)  the Company has paid or deposited with the Trustee a sum
     sufficient to pay

                    (A) all overdue installments of interest (including any
          Additional Interest) on the Debentures;

                    (B) the principal of (and premium, if any, on) the
          Debentures which have become due otherwise than by such declaration of
          acceleration and interest thereon at the rate borne by the Debentures;

                    (C) to the extent that payment of such interest is lawful,
          interest (including any Additional Interest) upon overdue installments
          of interest at the rate borne by the Debentures;

                    (D) all sums paid or advanced by the Trustee hereunder and
          the reasonable compensation, expenses, disbursements and advances of
          the Trustee, its agents and counsel; and

               (ii) all Events of Default with respect to Debentures, other
     than the non-payment of the principal of the Debentures which has become
     due solely by such acceleration, have been cured or waived as provided in
     Section 5.13. [If the Holders of a majority in principal amount of the
     Outstanding Debentures fail to rescind and annul such declaration and its
     consequences, the holders of a majority in liquidation amount of the
     Preferred Securities then outstanding shall have such right.]

Trustee.

          The Company covenants that if:

                                      48
<PAGE>

               (a) default is made in the payment of any installment of interest
(including any Additional Interest) on the Debentures when such interest becomes
due and payable and such default continues for a period of 30 days, or

               (b) default is made in the payment of the principal of (and
premium, if any, on) the Debentures whether at the Stated Maturity thereof or
upon redemption, by declaration or otherwise, the Company will, upon demand of
the Trustee, pay to it, for the benefit of the Holders of the Debentures, the
whole amount then due and payable on the Debentures for principal (and premium,
if any) and interest (including any Additional Interest), including, to the
extent that payment of such interest shall be lawful, interest on any overdue
principal (and premium, if any) and on any overdue installments of interest
(including any Additional Interest) at the rate borne by the Debentures, and, in
addition thereto, all amounts owing the Trustee under Section 6.7.

          If the Company fails to pay such amounts forthwith upon such demand,
the Trustee, in its own name and as trustee of an express trust, may institute a
judicial proceeding for the collection of the sums so due and unpaid, and may
prosecute such proceeding to judgement or final decree, and may enforce the same
against the Company or any other obligor upon the Debentures and collect the
moneys adjudged or decreed to be payable in the manner provided by law out of
the property of the Company or any other obligor upon the Debentures, wherever
situated.

          If an Event of Default occurs and is continuing, the Trustee may in
its discretion proceed to protect and enforce its rights and the rights of the
Holders of the Debentures by such appropriate judicial proceedings as the
Trustee shall deem most effectual to protect and enforce any such rights,
whether for the specific enforcement of any covenant or agreement in this
Indenture or in aid of the exercise of any power granted herein, or to enforce
any other proper remedy.

          Section 5.4  Trustee May File Proofs of Claim.  In case of the
                       --------------------------------
pendency of any receivership, insolvency, liquidation, bankruptcy,
reorganization, arrangement, adjustment, composition or other judicial
proceeding relative to the Company or any other obligor upon the Debentures:

               (a) the Trustee (irrespective of whether the principal of the
Debentures shall then be due and payable as therein expressed or by declaration
or

                                      49
<PAGE>

otherwise and irrespective of whether the Trustee shall have made any demand on
the Company for the payment of overdue principal (and premium, if any) or
interest (including any Additional Interest)) shall be entitled and empowered,
by intervention in such proceeding or otherwise,

                    (i)   to file and prove a claim for the whole amount of
     principal (and premium, if any) and interest (including any Additional
     Interest) owing and unpaid in respect to the Debentures and to file such
     other papers or documents as may be necessary or advisable and to take any
     and all actions as are authorized under the Trust Indenture Act in order to
     have the claims of the Holders and any predecessor to the Trustee under
     Section 6.7 allowed in any such judicial proceedings; and

                    (ii)  in particular, the Trustee shall be authorized to
     collect and receive any moneys or other property payable or deliverable on
     any such claims and to distribute the same in accordance with Section 5.6;
     and

               (b)  any custodian, receiver, assignee, trustee, liquidator,
sequestrator (or other similar official) in any such judicial proceeding is
hereby authorized by each Holder to make such payments to the Trustee for
distribution in accordance with Section 5.6, and in the event that the Trustee
shall consent to the making of such payments directly to the Holders, to pay to
the Trustee any amount due to it and any predecessor Trustee under Section 6.7;

          Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Debentures
or the rights of any Holder thereof, or to authorize the Trustee to vote in
respect of the claim of any Holder in any such proceeding; provided, however,
that the Trustee may, on behalf of the Holders, vote for the election of a
trustee in bankruptcy or similar official and be a member of a creditors' or
other similar committee.

thereto, and any such proceeding instituted by the Trustee shall be brought in
its own name as trustee of an express trust, and any recovery of judgement
shall, after provision for the payment of

                                      50

                       ------------------------------
collected or to be applied by the Trustee with respect to the Debentures
pursuant to this Article shall be applied in the following order, at the date or
dates fixed by the Trustee and, in case of the distribution of such money or
property on account of principal (or premium, if any) or interest (including any
Additional Interest), upon presentation of the Debentures and the notation
thereon of the payment if only partially paid and upon surrender thereof if
fully paid:

          FIRST:  To the payment of all amounts due the Trustee and any
predecessor Trustee under Section 6.7;

          SECOND:  To the payment of the amounts then due and unpaid upon the
Debentures for principal (and premium, if any) and interest (including any
Additional Interest), in respect of which or for the benefit of which such money
has been collected, ratably, without preference or priority of any kind,
according to the amounts due and payable on the Debentures for principal (and
premium, if any) and interest (including any Additional Interest), respectively;

                       -------------------
including a holder of Preferred Securities acting to enforce the rights of the
Property Trustee as a Holder of the Debentures pursuant to Section 6.8 of the
Trust Agreement,] shall have any right to institute any proceeding, judicial or
otherwise, with respect to this Indenture or for the appointment of a receiver,
assignee, trustee, liquidator, sequestrator (or other similar official) or for
any other remedy hereunder, unless:

               (a) such Holder has previously given written notice to the
Trustee of a continuing Event of Default;

                                      51
<PAGE>

               (b) [if the Trust is not the sole Holder of the Outstanding
Debentures,] the Holders of not less than 25% in principal amount of the
Outstanding Debentures shall have made written request to the Trustee to
institute proceedings in respect of such Event of Default in its own name as
Trustee hereunder;

               (c) such Holder or Holders have offered to the Trustee reasonable
indemnity against the costs, expenses and liabilities to be incurred in
compliance with such request;

               (d) the Trustee for 60 days after its receipt of such notice,
request and offer of indemnity has failed to institute any such proceeding; and

               (e) no direction inconsistent with such written request has been
given to the Trustee during such 60-day period by the Holders of a majority in
principal amount of the Outstanding Debentures;

it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing of any provision
of this Indenture to affect, disturb or prejudice the rights of any other
Holders of the Debentures, or to obtain or to seek to obtain priority or
preference over any other of such Holders or to enforce any right under this
Indenture, except in the manner herein provided and for the equal and ratable
benefit of all such Holders.

the Holder of any Debenture shall have the right which is absolute and
unconditional to receive payment of the principal of (and premium, if any) and
(subject to Section 3.7) interest (including any Additional Interest) on such
Debenture on the Maturity [or to convert such Debenture in accordance with
Article 13] and to institute suit for the enforcement of any such payment and
right to convert, and such right shall not be impaired without the consent of
such Holder. [For so long as any Preferred Securities remain Outstanding, to the
fullest extent permitted by law and subject to the terms of this Indenture and
the Trust Agreement, upon an Event of Default specified in Sections 5.1(a) or
5.1(b), any holder of Preferred Securities shall have the right to institute a
proceeding directly against the Company, for enforcement of payment to such
holder of the principal amount of or interest on Debentures having a principal
amount equal to the liquidation amount of the Preferred Securities of such
holder (a "Direct Action"). Notwithstanding any payment made to such holder of
Preferred Securities by the Company in connection with a Direct Action, the
Company shall

remain obligated to pay the principal of or interest on the Debentures held by
the Trust or the Property Trustee. In connection with any such Direct Action,
the rights of the Company will be subrogated to the rights of any holder of the
Preferred Securities to the extent of any payment made by the Company to such
holder of Preferred Securities as a result of such Direct Action. Except as set
forth in this Section, the holders of Preferred Securities shall have no right
to execute any right or remedy available to the Holders of or in respect of, the
Debentures.]

          Section 5.9  Restoration of Rights and Remedies.  If the Trustee or
                       ----------------------------------
any Holder has instituted any proceeding to enforce any right or remedy under
this Indenture and such proceeding has been discontinued or abandoned for any
reason, or has been determined adversely to the Trustee or to such Holder, then
and in every such case the Company, the Trustee and the Holder shall, subject to
any determination in such proceeding, be restored severally and respectively to
their former positions hereunder, and thereafter all rights and remedies of the
Trustee and the Holders shall continue as though no such proceeding had been
instituted.

          Section 5.10 Rights and Remedies Cumulative.  Except as otherwise
                       ------------------------------
provided in the last paragraph of Section 3.6, no right or remedy herein
conferred upon or reserved to the Trustee or to the Holders is intended to be
exclusive of any other right or remedy, and every right and remedy shall, to the
extent permitted by law, be cumulative and in addition to every other right and
remedy given hereunder or now or hereafter existing at law or in equity or
otherwise.  The assertion or employment of any right or remedy hereunder, or
otherwise, shall not prevent the concurrent assertion or employment of any other
appropriate right or remedy.

          Section 5.11 Delay or Omission Not Waiver.  No delay or omission of
                       ----------------------------

accruing upon any Event of Default shall impair any such right or remedy, or
constitute a waiver of any such Event of Default or an acquiescence therein.

          Every right and remedy given by this Article or by law to the Trustee
or to the Holders may be exercised from time to time, and as often as may be
deemed expedient, by the Trustee or by the Holders, as the case may be.

                       ------------------
principal amount of the Outstanding Debentures of any series shall have the
right to direct the time, method and place of conducting any proceeding for any
remedy available to the

<PAGE>

Trustee or exercising any trust or power conferred on the Trustee, with respect
to the Debentures of such series, provided that:

               (a) such direction shall not be in conflict with any rule of law
or with this Indenture,

               (b) the Trustee may take any other action deemed proper by the
Trustee which is not inconsistent with such direction, and

               (c) subject to the provisions of Section 6.1, the Trustee shall
have the right to decline to follow such direction if the Trustee in good faith
shall, by a Responsible Officer or Officers of the Trustee, determine that the
proceeding so directed would be unjustly prejudicial to the Holders not joining
in any such direction or would involve the Trustee in personal liability.

          Upon receipt by the Trustee of any written notice directing the time,
method or place of conducting any such proceeding or exercising any such trust
or power, with respect to the Debentures and, if all or part of the Debentures
is represented by a Global Security, a record date shall be established for
determining Holders of Outstanding Debentures entitled to join in such notice,
which record date shall be at the close of business on the day the Trustee
receives such notice.  The Holders on such record date, or their duly designated
proxies, and only such Persons, shall be entitled to join in such notice,
whether or not such Holders remain Holders after such record date, provided,
                                                                   --------
that, unless the Holders of a majority in principal amount of the Outstanding
Debentures shall have joined in such notice prior to the day which is 90 days
after such record date, such notice shall automatically and without further
action by any Holder be canceled and of no further effect.  Nothing in this
paragraph shall prevent a Holder, or a proxy of a Holder, from giving, after
expiration of such 90-day period, a new notice identical to a notice which has
been canceled pursuant to the proviso to the preceding sentence, in which event
a new record date shall be established pursuant to the provisions of this
Section 5.12.

          Section 5.13 Waiver of Past Defaults.  Subject to Section 9.2 hereof,
                       -----------------------
the Holders of not less than a majority in principal amount of the Outstanding
Debentures of any series may on behalf of the Holders of all the Debentures
of such series waive any past default hereunder with respect to Debentures and
its consequences, except a default:

               (a) in the payment of the principal of (or premium, if any) or
interest (including any Additional Interest) on the Debentures (unless such
default

                                      54

has been cured and a sum sufficient to pay all matured installments of interest
and principal due otherwise than by acceleration has been deposited with the
Trustee), or

               (b) in respect of a covenant or provision hereof which under
Article 9 cannot be modified or amended without the consent of the Holder of
each Outstanding Debenture[; provided, however, that if the Debentures are held
                             --------  -------
by the Trust or a trustee of the Trust, such waiver shall not be effective until
the holders of a majority in liquidation amount of Preferred Securities shall
have consented to such waiver; provided, further, that if the consent of the
                               --------  -------
Holder of each outstanding Debenture is required, such waiver shall not be
effective until each holder of the Trust Securities shall have consented to such
waiver].

          Upon any such waiver, such default shall cease to exist, and any Event
of Default arising therefrom shall be deemed to have been cured, for every
purpose of this Indenture, but no such waiver shall extend to any subsequent or
other default or impair any right consequent thereon.  [If the Holders of a
majority in aggregate principal amount of the Outstanding Debentures fail to
waive such Event of Default, the holders of a majority in aggregate liquidation
amount of Preferred Securities shall have such right.]  No such rescission shall
affect any subsequent default or impair any right consequent thereon.

          Section 5.14 Undertaking for Costs.  All parties to this Indenture
                       ---------------------
agree, and each Holder of any Debenture by his acceptance thereof shall be
deemed to have agreed, that any court may in its discretion require, in any suit
for the enforcement of any right or remedy under this Indenture, or in any suit
against the Trustee for any action taken or omitted by it as Trustee the filing
by any party litigant in such suit of an undertaking to pay the costs of such
suit, and that such court may in its discretion assess reasonable costs,
including reasonable attorneys' fees, against any party litigant in such suit,
having due regard to the merits and good faith of the claims or defenses made by
such party litigant; but the provisions of this Section shall not apply to any
suit instituted by the Trustee, to any suit instituted by any Holder, or group
of Holders, holding in the aggregate more than 10% in principal amount of the
Outstanding Debentures, or to any suit instituted by any Holder for the
enforcement of the payment of the principal of (or premium, if any) or interest
(including any Additional Interest) on the Debentures on or after the Maturity
of the Debentures or to convert a Debenture in accordance with Article 13.

          Section 5.15 Waiver of Usury, Stay, or Extension Laws.  The Company
                       ----------------------------------------
covenants (to the extent that it may lawfully do so) that it will not at any
time

                                      55

insist upon, or plead, or in any manner whatsoever claim or take the
benefit or advantage of, any usury, stay or extension law wherever enacted, now
or at any time hereafter in force, which may affect the covenants or the
performance of this Indenture; and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such
law, and covenants that it will not hinder, delay or impede the execution of any
power herein granted to the Trustee, but will suffer and permit the execution of
every such power as though no such law had been enacted.

          Section 6.1  Certain Duties and Responsibilities.  (a)  Except during
                       -----------------------------------
the continuance of an Event of Default,

                       (i)   the Trustee undertakes to perform such duties and
     only such duties as are specifically set forth in this Indenture, and no
     implied covenants or obligations shall be read into this Indenture against
     the Trustee; and

                       (ii)  in the absence of bad faith on its part, the
     Trustee may conclusively rely, as to the truth of the statements and the
     correctness of the opinions expressed therein, upon certificates or
     opinions furnished to the Trustee and conforming to the requirements of
     this Indenture, but in the case of any such certificates or opinions which
     by any provisions hereof are specifically required to be furnished to the
     Trustee, the Trustee shall be under a duty to examine the same to determine
     whether or not they conform to the requirements of this Indenture.

                 (b)   In case an Event of Default has occurred and is
continuing, the Trustee shall exercise such of the rights and powers vested in
it by this Indenture, and use the same degree of care and skill in their
exercise, as a prudent person would exercise or use under the circumstances in
the conduct of his own affairs.

                                      56
<PAGE>

                 (c)   No provision of this Indenture shall be construed to
relieve the Trustee from liability for its own negligent action, its own
negligent failure to act, or its own willful misconduct except that

                       (i)   this Subsection shall not be construed to limit the
     effect of Subsection (a) of this Section;

                       (ii)  the Trustee shall not be liable for any error of
     judgment made in good faith by a Responsible Officer, unless it shall be
     proved that the Trustee was negligent in ascertaining the pertinent facts;
     and

                       (iii) the Trustee shall not be liable with respect to any
     action taken or omitted to be taken by it in good faith in accordance with
     the direction of Holders pursuant to Section 5.12 relating to the time,
     method and place of conducting any proceeding for any remedy available to
     the Trustee, or exercising any trust or power conferred upon the Trustee,
     under this Indenture.

                 (d)   No provision of this Indenture shall require the Trustee
to expend or risk its own funds or otherwise incur any financial liability in
the performance of any of its duties hereunder, or in the exercise of any of its
rights or powers, if there shall be reasonable grounds for believing that
repayment of such funds or adequate indemnity against such risk or liability is
not reasonably assured to it.

                 (e)   Whether or not therein expressly so provided, every
provision of this Indenture relating to the conduct or affecting the liability
of or affording protection to the Trustee shall be subject to the provisions of
this Section.

                      ------------------
by a Responsible Officer of the Trustee of the occurrence of any default
hereunder, the Trustee shall transmit by mail to all Holders of Debentures, as
their names and addresses appear in the Securities Register, notice of such
default hereunder known to the Trustee, unless such default shall have been
cured or waived; provided, however, that, except in the case of a default in the
payment of the principal of (or premium, if any) or interest (including any
Additional Interest) on Debenture, the Trustee shall be protected in withholding
such notice if and so long as the board of directors, the executive committee or
a trust committee of directors and/or Responsible Officers of the Trustee in
good faith determines that the withholding of

                                      57
<PAGE>

such notice is in the interests of the Holders of Debentures; and provided,
                                                                  --------
further, that, except in the case of any default of the character specified in
- -------
Section 5.1(c), no such notice to Holders of the Debentures shall be given until
at least 30 days after the occurrence thereof. For the purpose of this Section,
the term "default" means any event which is, or after notice or lapse of time or
both would become, an Event of Default.

          Section 6.3  Certain Rights of Trustee.  Subject to the provisions of

be herein specifically prescribed) may, in the absence of bad faith on its part,
rely upon an Officers' Certificate and an Opinion of Counsel;

               (d)  the Trustee may consult with counsel of its selection, and
the advice of such counsel or any Opinion of Counsel shall be full and complete
authorization and protection in respect of any action taken, suffered or omitted
by it hereunder in good faith and in reliance thereon;

               (e)  the Trustee shall be under no obligation to exercise any of
the rights or powers vested in it by this Indenture at the request or direction

expenses and liabilities which might be incurred by it in compliance with such
request or direction;

                                      58
<PAGE>

               (f)  the Trustee is not required to expend or risk its own funds
or otherwise incur personal financial liability in the performance of its duties
if the Trustee reasonably believes that repayment or adequate indemnity is not
reason ably assured to it.

into the facts or matters stated in any resolution, certificate, statement,
instrument, opinion, report, notice, request, direction, consent, order, bond,

it may see fit, and, if the Trustee shall determine to make such inquiry or
investigation, it shall be entitled to examine the books, records and premises
of the Company, personally or by agent or attorney;

               (h)  the Trustee may execute any of the trusts or powers
hereunder or perform any duties hereunder either directly or by or through
agents or attorneys and the Trustee shall not be responsible for any misconduct
or negligence on any part of any agent or attorney appointed with due care by it
hereunder; and

               (i)  the Trustee shall not be charged with knowledge of any
default unless either (i) a Responsible Officer shall have actual knowledge
thereof, or (ii) the Trustee shall have received written notice thereof from the
Company or any Holder of the Debentures.

          Section 6.4  Not Responsible for Recitals or Issuance of Debentures.
                       ------------------------------------------------------
The recitals contained herein and in the Debentures, except the Trustee's
certificates of authentication, shall be taken as the statements of the Company,
and the Trustee assumes no responsibility for their correctness.  The Trustee
makes no representations as to the validity or sufficiency of this Indenture
or of the Debentures.  The Trustee shall not be accountable for the use or
application by the Company of the Debentures or the proceeds thereof.

          Section 6.5  May Hold Debentures.  The Trustee, any Paying Agent,
                       -------------------
Securities Registrar or any other agent of the Company, in its individual or any
other capacity, may become the owner or pledgee of Debentures and, subject to

it would have if it were not Trustee, Paying Agent, Securities Registrar or such
other agent.

          Section 6.6  Money Held in Trust.  Money held by the Trustee in trust
                       -------------------

received by it hereunder except as otherwise agreed in writing with the Company.

          Section 6.7  Compensation and Reimbursement.  The Company agrees
                       ------------------------------

                                      59
<PAGE>

               (a)   to pay to the Trustee from time to time such compensation
for all services rendered by it hereunder in such amounts as the Company and the
Trustee shall agree from time to time (which compensation shall not be limited
by any provision of law in regard to the compensation of a trustee of an express
trust);

               (b)   to reimburse the Trustee upon its request for all
reasonable expenses, disbursements and advances incurred or made by the Trustee
in accordance with any provision of this Indenture (including the reasonable
compensation and the expenses and disbursements of its agents and counsel); and

               (c)   to indemnify the Trustee for, and to hold it harmless
against, any loss, liability or expense (including the reasonable compensation
and the expenses and disbursements of its agents and counsel) incurred without
negligence or bad faith, arising out of or in connection with the acceptance or
administration of this trust or the performance of its duties hereunder,
including the costs and expenses of defending itself against any claim or
liability in connection with the exercise or performance of any of its powers or
duties hereunder. This indemnification shall survive the resignation or removal
of the Trustee and the termination of this Indenture.

          To secure the Company's payment obligations in this Section, the
Company and the Holders agree that the Trustee shall have a lien prior to the
Debentures on all money or property held or collected by the Trustee except
assets held in trust to pay principal and premium, if any, or interest on
particular Debentures pursuant to the discharge and defeasance provisions
pursuant to Article 4, or pursuant to any redemption pursuant to Article 11
hereof if monies have been deposited for such redemption and notice has been
given and the Redemption Date has passed.  Such lien shall survive the
satisfaction and discharge of this Indenture.

          When the Trustee incurs expenses or renders services after an Event of
Default specified in Section 5.1(e) or (f) occurs, the expenses and the
compensation for the services are intended to constitute expenses of
administration under any Bankruptcy Reform Act of 1978 or a successor statute.

          Section 6.8  Disqualification; Conflicting Interests.  The Trustee
                       ---------------------------------------
shall be subject to the provisions of Section 310(b) of the Trust Indenture Act.
Nothing herein shall prevent the Trustee from filing with the Commission the
application referred to in the second to last paragraph of Section 310(b) of the
Trust Indenture

                                      60

Act. The Trust Agreement and the Guarantee shall be deemed to be specifically
described in this Indenture for the purposes of clause (i) of the first proviso
contained in Section 310(b) of the Trust Indenture Act. The Trustee's services
as Guarantee Trustee and Trustee under the Trust Agreement shall not be deemed
to constitute conflicting interests.

                       ---------------------------------------
all times be a Trustee hereunder which shall be

               (b)  a corporation or other Person organized and doing business
under the laws of a foreign government that is permitted to act as Trustee

United States institutional trustees,

          in either case having a combined capital and surplus of at least
$50,000,000, subject to supervision or examination by Federal or State
authority.  If such corporation publishes reports of condition at least
annually, pursuant to law or to the requirements of the aforesaid supervising or
examining authority, then, to the purposes of this Section, the combined capital
and surplus of such corporation shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published.  If at
any time the Trustee shall cease to be eligible in accordance with the
provisions of this Section, it shall resign immediately in the manner and with
the effect hereinafter specified in this Article.  Neither the Company nor any
Person directly or indirectly controlling, controlled by or under common control
with the Company shall serve as Trustee hereunder.

<PAGE>

               (b)  The Trustee may resign at any time by giving written notice
thereof to the Company.  If an instrument of acceptance by a successor Trustee
shall not have been delivered to the Trustee within 30 days after the giving of
such notice of resignation, the resigning Trustee may petition any court of
competent jurisdiction for the appointment of a successor Trustee.

               (c)  The Trustee may be removed at any time by Act of the Holders
of a majority in principal amount of the Outstanding Debentures, delivered to
the Trustee and to the Company. If an instrument of acceptance by a successor
Trustee shall not have been delivered to the Trustee within 30 days after the
giving of such notice of resignation, the resigning Trustee may petition any
court of competent jurisdiction for the appointment of a successor Trustee.

               (d)  If at any time:

                    (i)   the Trustee shall fail to comply with Section 6.8
     after written request therefor by the Company or by any Holder who has been
     a bona fide Holder of a Debenture for at least six months, or

                    (ii)  the Trustee shall cease to be eligible under Section
     6.9 and shall fail to resign after written request therefor by the Company
     or by any such Holder, or

     be adjudged as bankrupt or insolvent or a receiver of the Trustee or of its
     property shall be appointed or any public officer shall take charge or
     control of the Trustee or of its property or affairs for the purpose of
     rehabilitation, conservation or liquidation,

then, in any such case, (A) the Company by Board  Resolution may remove the
Trustee, or (B) subject to Section 5.14, any Holder who has been a bona fide
Holder of a Debenture for at least six months may, on behalf of himself and all
other similarly situated Holders, petition any court of competent jurisdiction
for the removal of the Trustee and the appointment of a successor Trustee.

               (e)  If the Trustee shall resign, be removed or become incapable
of acting, or if a vacancy shall occur in the office of Trustee for any cause
with respect to the Debentures, the Company, by a Board Resolution, shall
promptly

                                      62
<PAGE>

appoint a successor Trustee. If, within one year after such resignation, removal
or incapability, or the occurrence of such vacancy, a successor Trustee with
respect to the Debentures shall be appointed by Act of the Holders of a majority
in principal amount of the Outstanding Debentures delivered to the Company and
the retiring Trustee, the successor Trustee so appointed shall, forthwith upon
its acceptance of such appointment, become the successor Trustee and supersede
the successor Trustee appointed by the Company. If no successor Trustee shall
have been appointed by the Company or the Holders and accepted appointment in
the manner hereinafter provided, any Holder who has been a bona fide Holder of a
Debenture for at least six months may, subject to Section 5.14, on behalf of
himself and all others similarly situated, petition any court of competent
jurisdiction for the appointment of a successor Trustee.

               (f)  The Company shall give notice of each resignation and each
removal of the Trustee and each appointment of a successor Trustee by mailing
written notice of such event by first-class mail, postage prepaid, to the
Holders of the Debentures as their name and addresses appear in the Securities
Register. Each notice shall include the name of the successor Trustee and the
address of its Corporate Trust Office.

          Section 6.11 Acceptance of Appointment by Successor.  (a)  In case of
                       --------------------------------------
the appointment hereunder of a successor Trustee, every such successor Trustee
so appointed shall execute, acknowledge and deliver to the Company and to the
retiring Trustee an instrument accepting such appointment, and thereupon the
resignation or removal of the retiring Trustee shall become effective and such
successor Trustee, without any further act, deed or conveyance, shall become
vested with all the rights, powers, trusts and duties of the retiring Trustee,
but, on the request of the Company or the Successor Trustee, such retiring
Trustee shall, upon payment of its charges, execute and deliver an instrument
transferring to such successor Trustee all the rights, powers and trusts of the
retiring Trustee and shall duly assign, transfer and deliver to such successor
Trustee all property and money held by such retiring Trustee hereunder.

               (b)  Upon request of any such successor Trustee, the Company
shall execute any and all instruments for more fully and certainly vesting in
and confirming to such successor Trustee all rights, power and trusts referred
to in paragraph (a) of this Section.

the time of such acceptance such successor Trustee shall be qualified and
eligible under this Article.

          Section 6.12 Merger, Conversion, Consolidation or Succession to
                       --------------------------------------------------
Business.  Any corporation into which the Trustee may be merged or converted or
- --------
with which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all of the corporate trust
business of the Trustee, shall be the successor of the Trustee and any agency
appointments of the Trustee hereunder, provided such corporation shall be
otherwise qualified and eligible under this Article, without the execution or
filing of any paper or any further act on the part of any of the parties hereto.
In case any Debentures shall have been authenticated, but not delivered, by the
Trustee then in office, any successor by merger, conversion or consolidation to
such authenticating Trustee may adopt such authentication and deliver the
Debentures so authenticated, and in case any Debentures shall not have been
authenticated, any successor to the Trustee may authenticate such Debentures
either in the name of any predecessor Trustee or in the name of such successor
Trustee, and in all cases the certificate of authentication shall have the full
force which it is provided anywhere in the Debentures or in this Indenture that
the certificate of the Trustee shall have.

          Section 6.13 Preferential Collection of Claims Against Company.  If
                       -------------------------------------------------
and when the Trustee shall be or become a creditor of the Company (or any other
obligor upon the Debentures), the Trustee shall be subject to the provisions of
the Trust Indenture Act regarding the collection of claims against the Company
(or any such other obligor).

          Section 6.14 Appointment of Authenticating Agent.  The Trustee may
                       -----------------------------------
appoint an Authenticating Agent or Agents with respect to the Debentures which
shall be authorized to act on behalf of the Trustee to authenticate the
Debentures issued upon exchange, registration of transfer or partial redemption
thereof, and Debentures so authenticated shall be entitled to the benefits of
this Indenture and shall be valid and obligatory for all purposes as if
authenticated by the Trustee hereunder.  Wherever reference is made in this
Indenture to the authentication and delivery of Debentures by the Trustee or the
Trustee's certificate of authentication, such reference shall be deemed to
include authentication and delivery on behalf of the Trustee by an
Authenticating Agent.  Each Authenticating Agent shall be acceptable to the
Company and shall at all times be a corporation organized and

                                      64
<PAGE>

doing business under the laws of the United States of America, or of any State,
Territory or the District of Columbia, authorized under such laws to act as
Authenticating Agent, having a combined capital and surplus of not less than
$50,000,000 and subject to supervision or examination by Federal or State
authority. If such Authenticating Agent publishes reports of condition at least
annually, pursuant to law or to the requirements of said supervising or
examining authority, then for the purposes of this Section the combined capital
and surplus of such Authenticating Agent shall be deemed to be its combined
capital and surplus as set forth in its most recent report of condition so
published. If at any time an Authenticating Agent shall cease to be eligible in
accordance with the provisions of this Section, such Authenti cating Agent shall
resign immediately in the manner and with the effect specified in this Section.

          Any corporation into which an Authenticating Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which such Authenticating Agent
shall be a party, or any corporation succeeding to all or substantially all of
the corporate trust business of an Authenticating Agent shall be the successor
Authenticating Agent hereunder, provided such corporation shall be otherwise
eligible under this Section, without the execution or filing of any paper or any
further act on the part of the Trustee or the Authenticating Agent.

          An Authenticating Agent may resign at any time by giving written
notice thereof to the Trustee and to the Company.  The Trustee may at any time
terminate the agency of an Authenticating Agent by giving written notice thereof
to such Authenticating Agent and to the Company.  Upon receiving such a notice
of resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee may appoint a successor Authenticating
Agent which shall be acceptable to the Company and shall give notice of such
appointment in the manner provided in Section 1.6 to all Holders of the
Debentures.  Any successor Authenticating Agent upon acceptance of its
appointment hereunder shall become vested with all the rights, powers and duties
of its predecessor hereunder, with like effect as if originally named as an
Authenticating Agent.  No successor Authenticating Agent shall be appointed
unless eligible under the provision of this Section.

               (a)  in case the Company shall consolidate with or merge into
another Person or convey, transfer or lease its properties and assets

               (b)  immediately after giving effect to such transaction, no

               (d)  the Company has delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that such consolidation,
merger, conveyance, transfer or lease and any such supplemental indenture
complies with this Article and that all conditions precedent herein provided for

                       ---------------------------------
tion or merger by the Company with or into any other Person, or any conveyance,
transfer or lease by the Company of its properties and assets substantially as
an entirety to any Person in accordance with Section 8.1, the successor
corporation formed by such consolidation or into which the Company is merged or

          Such successor corporation may cause to be signed, and may issue
either in its own name or in the name of the Company, any or all of the
Debentures issuable hereunder which theretofore shall not have been signed by
the Company and delivered to the Trustee, and, upon the Company Order of such
successor corporation instead of the Company and subject to all the terms,
conditions and limitations in this Indenture prescribed, the Trustee shall
authenticate and shall deliver any Debentures which previously shall have been
signed and delivered by the officers of the Company to the Trustee for
authentication pursuant to such provisions and any Debentures which such
successor corporation thereafter shall cause to be signed and delivered to the
Trustee on its behalf for the purpose pursuant to such provisions. All the
Debentures so issued shall in all respects have the same legal rank and benefit
under this Indenture as the Debentures theretofore or thereafter issued in
accordance with the terms of this Indenture as though all of such Debentures had
been issued at the date of the execution hereof.

          In case of any such consolidation, merger, sale, conveyance or lease,
such changes in phraseology and form may be made in the Debentures thereafter to
be issued as may be appropriate.

                                   COVENANTS

          Section 10.1   Payment of Principal, Premium and Interest.  The
                        -------------------------------------------
Company covenants and agrees for the benefit of the Holders of the Debentures
that it will duly and punctually pay the principal of (and premium, if any) and
interest (including Additional Interest) on the Debentures in accordance with
the terms of the Debentures and this Indenture.

              Section 10.2 Maintenance of Office or Agency.  The Company will
              --------------------------------------------
maintain in the United States an office or agency where Debentures may be
presented or surrendered for payment and an office or agency where Debentures
may be surrendered for registration of transfer or exchange and where notices
and demands to or upon the Company in respect of the Debentures and this
Indenture may be served. The Company initially appoints the Trustee, acting
through its Corporate Trust Office, as its agent for said purposes. The Company
will give prompt written notice to the Trustee of any change in the location of
any such office or agency. If at any time the Company shall fail to maintain
such office or agency or shall fail to furnish the Trustee with the address
thereof, such presentations, surrenders, notices and demands may be made or
served at the Corporate Trust Office of the Trustee, and the Company hereby
appoints the Trustee as its agent to receive all such presentations, surrenders,
notices and demands.

          The Company may also from time to time designate one or more other
offices or agencies where the Debentures may be presented or surrendered for any
or all of such purposes, and may from time to time rescind such designations;
provided, however, that no such designation or rescission shall in any manner
relieve the Company of its obligation to maintain an office or agency in the
United States for such purposes.  The Company will give prompt written notice to
the Trustee of any such designation and any change in the location of any such
office or agency.

          Section 10.3 Money for Debenture Payments to Be Held in Trust.  If the
                       ------------------------------------------------
Company shall at any time act as its own Paying Agent with respect to the
Debentures, it will, on or before each due date of the principal of (and
premium, if any) or interest on any of the Debentures, segregate and hold in
trust for the benefit of the Persons entitled thereto a sum sufficient to pay
the principal (and premium, if any) or interest so becoming due until such sums
shall be paid to such Persons or otherwise disposed of as herein provided, and
will promptly notify the Trustee of its failure so to act.

          Whenever the Company shall have one or more Paying Agents, it will, on
or before each due date of the principal of or interest on the Debentures,
deposit with a Paying Agent a sum sufficient to pay the principal (and premium,
if any) or interest so becoming due, such sum to be held in trust for the
benefit of the Persons entitled to such principal and premium (if any) or
interest, and (unless such Paying Agent is the Trustee) the Company will
promptly notify the Trustee of its failure so to act.

          The Company will cause each Paying Agent other than the Trustee to
execute and deliver to the Trustee an instrument in which such Paying Agent
shall agree with the Trustee, subject to the provisions of this Section, that
such Paying Agent will:

          (a)  hold all sums held by it for the payment of the principal of (and
premium, if any) or interest on Debentures in trust for the benefit of the
Persons entitled thereto until such sums shall be paid to such Persons or
otherwise disposed of as herein provided;

          (b)  give the Trustee notice of any default by the Company (or any
other obligor upon the Debentures) in the making of any payment of principal
(and premium, if any) or interest;

                                      75
<PAGE>


          (c)  at any time during the continuance of any such default, upon the
written request of the Trustee, forthwith pay to the Trustee all sums so held in
trust by such Paying Agent; and

          (d)  comply with the provisions of the Trust Indenture Act applicable
to it as a Paying Agent.

          The Company may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Company Order direct any Paying Agent to pay, to the Trustee all sums held in
trust by the Company or such Paying Agent, such sums to be held by the Trustee
upon the same trusts as those upon which such sums were held by the Company or
such Paying Agent, and, upon such payment by the Company or any Paying Agent to
the Trustee, such Paying Agent shall be released from all further liability with
respect to such money.

          Any money deposited with the Trustee or any Paying Agent, or then held
by the Company, in trust for the payment of the principal of (and premium, if
any) or interest on any Debenture and remaining unclaimed for two years after
such principal (and premium, if any) or interest has become due and payable
shall (unless otherwise required by mandatory provision of applicable escheat or
abandoned or unclaimed property law) be paid on Company Request, after all
payments owing the Trustee have been paid, to the Company, or (if then held by
the Company) shall (unless otherwise required by mandatory provision of
applicable escheat or abandoned or unclaimed property law) be discharged from
such trust; and the Holder of such Debenture shall thereafter, as an unsecured
general creditor, look only to the Company for payment thereof, and all
liability of the Trustee or such Paying Agent with respect to such trust money,
and all liability of the Company as trustee thereof, shall thereupon cease.

or discharge or cause to be paid or discharged, before the same shall become
delinquent, (a) all taxes, assessments and governmental charges levied or
imposed upon the Company or upon the income, profits or property of the Company,
and (b) all lawful claims for labor, materials and supplies which, if unpaid,
might by law become a lien upon the property of the Company; provided, however,
                                                             --------  -------
that the Company shall not be required to pay or discharge or cause to be paid
or discharged any such tax, assessment, charge or claim whose amount,
applicability or validity is being contested in good faith by appropriate
proceedings.

covering the preceding calendar year, stating whether or not to the best
knowledge of the signers thereof the Company is in default in the performance,

be determined without regard to any grace period or requirement of notice
provided pursuant to the terms of this Indenture.

          Section 10.6 Waiver of Certain Covenants.  The Company may omit in any
                       ---------------------------
particular instance to comply with any covenant or condition set forth in this
Article 10, if before or after the time for such compliance the Holders of at
least a majority in principal amount of the Outstanding Debentures, by Act of
such Holders, either waive such compliance in such instance or generally waive
compliance with such covenant or condition, but no such waiver shall extend to
or affect such covenant or condition except to the extent so expressly waived,
and, until such waiver shall become effective, the obligations of the Company in
respect of any such covenant or condition shall remain in full force and effect.

provisions hereof where such express mention is not made; provided, however,
that the extension of an interest payment period pursuant to Section 3.11 or
the Debentures shall not extend the payment of any Additional Sums that may be
due and payable during such interest payment period.]

Price therein specified, including any accrued interest (and any Additional
Interest) thereon, and from and after such date (unless the Company shall
default in the payment of the Redemption Price or any accrued interest on

interest.  Upon surrender of any such Debenture for redemption in accordance
with said notice, such Debenture shall be paid by the Company at the Redemption
Price, including any accrued interest (and any Additional Interest) to the
Redemption Date, provided, however, that installments of interest on Debentures

likewise covenants and agrees, that, to the extent and in the manner hereinafter
set forth in this Article, the payment of the principal of (and premium, if any)

Debentures are hereby expressly made subordinate and subject in right of payment
to the prior payment in full in cash of all amounts then due and payable in
respect of all Senior Debt (whether outstanding on the date hereof or hereafter
created, incurred, assumed or guaranteed), and that the subordination is for the
benefit of the holders of Senior Debt and that no payment on account of
principal of, premium, if any, or interest on the Debentures and no acquisition
of, or payment on account of any sinking fund for, the Debentures may be made
unless full payment of all amounts then due for principal, premium, if any, and
interest then due on all Senior Debt (by maturity, lapse of time, acceleration
or otherwise) has been made or duly provided for in cash or in a manner
satisfactory to the holders of such Senior Debt.

any distribution of the Company's assets in connection with any dissolution,
winding up, liquidation or reorganization of the Company, whether voluntary or
involuntary, in bankruptcy, insolvency or receivership proceedings (each such
event, if any, herein sometimes referred to as a "Proceeding"), or upon an
assignment for the benefit of creditors or otherwise: (i) all Senior Debt
(including without limitation all interest accruing on or after the filing of
any petition in bankruptcy relating to the Company at the relevant contractual
rate, whether or not such claim for post-petition interest is allowed in such
proceeding) must be paid in full in cash before the Holders of the Debentures
are entitled to any payments or distributions of any kind or character
(including any payment or distribution which may be payable or deliverable by
reason of the payment of any other Debt of the Company (including the
Debentures) subordinated to the payment of the Debentures), and (ii) any payment
or distribution of the Company's assets of any kind or character, whether in
cash, securities or other property, which would otherwise (but for these
subordination provisions) be payable or deliverable in respect of the Debentures
shall be paid or delivered directly to the holders of such Senior Debt (or their
representative or trustee) in accordance with the priorities then existing among
such holders until all

forth herein, any payment or distribution of assets of any kind or character is
made on the Debentures at a time when the respective payment is not permitted to
be made as a result of the subordination provisions described above and before
all Senior Debt is paid in full in cash, the Trustee or the Holders of the
Debentures receiving such payment will be required to pay over such payment or
distribution to the holders of such Senior Debt.

distribution of any kind or character" shall not be deemed to include shares of
stock of the Company as reorganized or readjusted, or securities of the Company

readjustment which securities are subordinated in right of payment to all then
outstanding Senior Debt to substantially the same extent as the Debentures are
so subordinated as provided in this Article.  The consolidation of the Company
with, or the merger of the Company into, another Person or the liquidation or
dissolution of the Company following the sale of all or substantially all of its
properties and assets as an entirety to another Person upon the terms and
conditions set forth in Article 8 shall not be deemed a Proceeding for the
purposes of this Section if the Person formed by such consolidation or into
which the Company is merged or the Person which acquires by sale such properties
and assets as an entirety, as the case may be, shall, as a part of such
consolidation, merger, or sale comply with the conditions set forth in Article
Eight.

Senior Debt, or in the event that any event of default with respect to any
Senior Debt shall have occurred and be continuing and shall have resulted in
such Senior Debt becoming or being able to be declared due and payable prior to
the date it would otherwise have become due and payable, unless and until such
event of default shall have been waived or shall have ceased to exist and such
acceleration shall have been rescinded or annulled, or (b) in the event any
judicial proceeding shall be pending with respect to any such default in payment
or such event or default, then, no payment or distribution of any kind or
character, whether in cash, properties or Debentures shall be made by the
Company on account of principal of (or premium, if any) or interest (including
any Additional Interest), if any, on the Debentures or on

Subsidiary other than payments made from funds on deposit pursuant to Section
4.1 or from funds on deposit for the redemption of Debentures for which notice
of redemption has been given and the Redemption Date has passed.

          The Company shall give prompt written notice to the Trustee of any
default of the type described in the preceding paragraph in respect of Senior
Debt; provided that no failure to give such a notice shall have any effect
whatsoever on the subordination provisions described herein.

make any payment to the Trustee or the Holder of the Debentures prohibited by
the foregoing provisions of this Section, and if such fact shall, at or prior to
the time of such payment, have been made known as set forth in Section 12.9, to
the Trustee or, as the case may be, such Holder, then and in such event such
payment shall be paid over and delivered forthwith to the Company.

          The provisions of this Section shall not apply to any payment with
respect to which Section 12.2 would be applicable.

prevent (a) the Company, at any time except during the pendency of any
Proceeding referred to in Section 12.2 or under the conditions described in
Sections 12.3, from making payments at any time of principal of (and premium, if
any) or interest on the Debentures, or (b) except with respect to the payment
over provisions of this Article 12, the application by the Trustee of any money
deposited with it hereunder to the payment of or on account of the principal of
(and premium, if any) or interest (including any Additional Interest) on the
Debentures or the retention of such payment by the Holders, if, at the time of
such application by the Trustee, the Trustee did not have actual knowledge that
such payment would have been prohibited by the provisions of this Article.

Subject to the payment in full in cash of all Senior Debt, or the provision for
such payment in cash or cash equivalents or otherwise in a manner satisfactory
to the holders of Senior Debt, the Holders of the Debentures shall be subrogated
to the extent of the payments or distributions made to the holders of such
Senior Debt pursuant to the provisions of this Article (equally and ratably with
the holders of all

indebtedness of the Company which by its express terms is subordinated to Senior
Debt of the Company to substantially the same extent as the Debentures are
Subordinated to the Senior Debt and is entitled to like rights of subrogation

to the rights of the holders of such Senior Debt to receive payments and
distributions of cash, property and securities applicable to the Senior Debt

shall be paid in full. For purposes of such subrogation, no payments or
distributions to the holders of the Senior Debt of any cash, property or
securities to which the Holders of the Debentures or the Trustee would be
entitled except for the provisions of this Article, and no payments pursuant to
the provisions of this Article to the holders of Senior Debt by Holders of the
Debentures or the Trustee, shall, as among the Company, its creditors other than
holders of Senior Debt, and the Holders of the Debentures, be deemed to be a
payment or distribution by the Company to or on account of the Senior Debt.

Proceeding, subject to the rights, if any, under this Article of the holders of
Senior Debt to receive cash, property and securities otherwise payable or
deliverable to the Trustee or such Holder.

Debenture by his or her acceptance thereof authorizes and directs the Trustee on
his or her behalf to take such action as may be necessary or appropriate to
acknowledge or effectuate the subordination provided in this Article and
appoints the Trustee his or her attorney-in-fact for any and all such purposes.

provided shall at any time in any way be prejudiced or impaired by any act or
failure to act on the part of the Company or by any act or failure to act, in

terms, provisions and covenants of this Indenture, regardless of any knowledge
thereof that any such holder may have or be otherwise charged with.

          Section 12.9   Notice to Trustee.  The Company shall give prompt
                         -----------------
written notice to the Trustee of any fact known to the Company which would
prohibit the making of any payment to or by the Trustee in respect of the
Debentures. Notwithstanding the provisions of this Article or any other
provision of this Indenture, the Trustee shall not be charged with knowledge
of the existence of any facts which would prohibit the making of any payment to
or by the Trustee in respect of the Debentures, unless and until the Trustee
shall have received written notice thereof from the Company or a person
representing itself as a holder of Senior Debt or from any trustee, agent or
representative therefor (whether or not the facts contained in such notice are
true).

referred to in this Article, the Trustee, subject to the provisions of Article
6, and the Holders of the Debentures shall be entitled to rely upon any order or
decree entered by any court of competent jurisdiction in which a Proceeding is
pending, or a certificate of the trustee in bankruptcy, receiver, liquidating
trustee, custodian, assignee for the benefit of creditors, agent or other Person
making such payment or distribution, delivered to the Trustee or to the Holders
of Debentures, for the purpose of ascertaining the Persons entitled to
participate in such payment or distribution, the holders of the Senior Debt and
other indebtedness of the Company, the amount thereof or payable thereon, the
amount or amounts paid or distributed thereon and all other facts pertinent
thereto or to this Article.

          Section 12.11  Trustee Not Fiduciary for Holders of Senior Debt. With
                         ------------------------------------------------
respect to the holders of the Senior Debt of the Company, the Trustee under
takes to perform or observe only such of its obligations and covenants as are
set forth in this Article 12, and no implied covenants or obligations with
respect to the holders of such Senior Debt shall be read into this Indenture
against Chase Manhattan Trust Company, National Association and/or the Trustee.
Chase Manhattan Trust Company, National Association and/or the Trustee shall not
be deemed to owe any fiduciary duty to the holders of such Senior Debt and,
subject to the

<PAGE>

provisions of Section 6.3, neither the Trustee (nor Chase Manhattan Trust
Company, National Association) shall be liable to the holder of any Senior Debt
if it shall pay over or deliver to Holders, the Company, or any other Person,

virtue of this Article 12 or otherwise.

shall be entitled to all the rights set forth in this Article with respect to
any Senior Debt which may at any time be held by it, to the same extent as any
other holder of Senior Debt, and, subject to the requirements of the Trust
Indenture Act, nothing in this Indenture shall deprive the Trustee of any of its
rights as such holder.

          Section 12.13  Article Applicable to Paying Agents.  In case at any
                         -----------------------------------
time any Paying Agent other than the Trustee shall have been appointed by the
Company and be then acting hereunder, the term "Trustee" as used in this Article
shall in such case (unless the context otherwise requires) be construed as
extending to and including such Paying Agent within its meaning as fully for all
intent and purposes as if such Paying Agent were named in this Article in
addition to or in place of the Trustee.

          Section 12.14  Certain Conversions or Exchanges Deemed Payment. For
                         -----------------------------------------------
the purpose of this Article only, (a) the issuance and delivery of junior
securities upon conversion or exchange of Debentures shall not be deemed to
constitute a payment or distribution on account of the principal of (or premium,
if any) or interest (including any Additional Interest) on the Debentures or on
account of the purchase or other acquisition of Debentures, and (b) the payment,
issuance or delivery of cash (including any payments for fractional shares),
property or securities (other than junior securities) upon conversion or
exchange of a Debenture shall be deemed to constitute payment on account of the
principal of such Debenture.  For the purpose of this Section, the term "junior
securities" means (i) shares of any stock of any class of the Company and (ii)
securities of the Company which are subordinated in right of payment to all
Senior Debt which may be outstanding at the time of issuance or delivery of such
securities to substantially the same extent as, or to a greater extent than, the
Debentures are so subordinated as provided in this Article.

          Section 12.15  Trust Moneys Not Subordinated.  Notwithstanding
                         -----------------------------
anything contained herein to the contrary (provided that at the time deposited,
                                           --------
such deposit did not violate any then outstanding Senior Debt), payments from
money or the proceeds of Government Obligations held in trust under Article 4 by
the Trustee

                                      90
<PAGE>

for the payment of principal of and interest on the Debentures shall not be
subordinated to the prior payment of any Senior Debt or subject to the
restrictions set forth in this Article 12, and none of the Holders shall be
obligated to pay over any such amount to the Company or any holder of Senior
Debt of the Company or any other creditor of the Company.


                                  ARTICLE XII

                            [CONVERSION OF DEBENTURES

          Section 13.1   Conversion Rights.  Subject to and upon compliance with
                         -----------------
the provisions of this Article, the Debentures are convertible, at the option of
the Holder, at any time prior to redemption or Maturity, into fully paid and
nonassessable shares of Common Stock of the Company at an initial conversion
rate of ______ shares of Common Stock for each $[1,000] in aggregate principal
amount of Debentures (equal to a conversion price of $______ per share of Common
Stock), subject to adjustment as described in this Article 13 (as adjusted the
"Conversion Price"). A Holder of Debentures may convert any portion of the
principal amount of the Debentures into that number of fully paid and
nonassessable shares of Common Stock (calculated as to each conversion to the
nearest 1/100th of a share) obtained by dividing the principal amount of the
Debentures to be converted by the Conversion Price. In case a Debenture or
portion thereof is called for redemption, such conversion right in respect of
the Debenture or portion so called shall expire at the close of business on the
Business Day immediately preceding the corresponding Redemption Date, unless the
Company defaults in making the payment due upon redemption.

          Section 13.2   Conversion Procedures.  (a)  In order to convert all or
                         ---------------------
a portion of the Debentures, the Holder thereof shall deliver to the [Property
Trustee, as] conversion agent or to such other agent appointed for such purposes
(the "Conversion Agent") an irrevocable Notice of Conversion setting forth the
principal amount of Debentures to be converted, together with the name or names,
if other than the Holder, in which the shares of Common Stock should be issued
upon conversion and, if such Debentures are definitive Debentures, surrender to
the Conversion Agent the Debentures to be converted, duly endorsed or assigned
to the Company or in blank. [In addition, a holder of Preferred Securities may
exercise its right under the Trust Agreement to convert such Preferred
Securities into Common Stock by delivering to the Conversion Agent an
irrevocable Notice of Conversion setting forth the information called for by the
preceding sentence and directing the Conversion

                                      91
<PAGE>

Agent (i) to exchange such Preferred Security for a portion of the Debentures
held by the Trust (at an exchange rate of $50 principal amount of Debentures for
each Preferred Security) and (ii) to immediately convert such Debentures, on
behalf of such holder, into Common Stock of the Company pursuant to this Article
13 and, if such Preferred Securities are in definitive form, surrendering such
Preferred Securities, duly endorsed or assigned to the Company or in blank. So
long as any Preferred Securities are outstanding, the Trust shall not convert
any Debentures except pursuant to a Notice of Conversion delivered to the
Conversion Agent by a holder of Preferred Securities.]

          If a Notice of Conversion is delivered on or after the Regular Record
Date and prior to the subsequent Interest Payment Date, the Holder of record on
the Regular Record Date will be entitled to receive the interest paid on the
subsequent Interest Payment Date on the portion of Debentures to be converted
notwithstanding the conversion thereof prior to such Interest Payment Date.
Except as otherwise provided in the immediately preceding sentence, in the case
of any Debenture which is converted, interest whose Stated Maturity is on or
after the date of conversion of such Debenture shall not be payable, and the
Company shall not make nor be required to make any other payment, adjustment or
allowance with respect to accrued but unpaid interest on the Debentures being
converted, which shall be deemed to be paid in full.  Each conversion shall be
deemed to have been effected immediately prior to the close of business on the
day on which the Notice of Conversion was received (the "Conversion Date") by
the Conversion Agent from the Holder or from a holder of the Preferred
Securities effecting a conversion thereof pursuant to its conversion rights
under the Trust Agreement, as the case may be.  The Person or Persons entitled
to receive the Common Stock issuable upon such conversion shall be treated for
all purposes as the record holder or holders of such Common Stock as of the
Conversion Date and such Person or Persons will cease to be a record Holder or
record Holders of the Debentures on that date.  As promptly as practicable on or
after the Conversion Date, the Company shall issue and deliver at the office of
the Conversion Agent, unless otherwise directed by the Holder or Holders in the
Notice of Conversion, a certificate or certificates for the number of full
shares of Common Stock issuable upon such conversion, together with the cash
payment, if any, in lieu of any fraction of any share to the Person or Persons
entitled to receive the same. The Conversion Agent shall deliver such
certificate or certificates to such Person or Persons.

          (b) The Company's delivery upon conversion of the fixed number of
shares of Common Stock into which the Debentures are convertible

                                      92
<PAGE>

(together with the cash payment, if any, in lieu of fractional shares) shall be
deemed to satisfy the Company's obligation to pay the principal amount at
Maturity of the portion of Debentures so converted and any unpaid interest
(including Additional Interest) accrued on such Debentures at the time of such
conversion.

          (c) No fractional shares of Common Stock will be issued as a result of
conversion, but in lieu thereof, the Company shall pay to the Conversion Agent a
cash adjustment in an amount equal to the same fraction of the Current Market
Price with respect to such fractional interest on the date on which the
Debentures or Preferred Securities, as the case may be, were duly surrendered to
the Conversion Agent for conversion, and the Conversion Agent in turn will make
such payment, if any, to the Holder of the Debentures or the holder of the
Preferred Securities so converted.

          (d) In the event of the conversion of any Debenture in part only, a
new Debenture or Debentures for the unconverted portion thereof will be issued
in the name of the Holder thereof upon the cancellation of the Debenture
converted in part in accordance with Section 3.5.

          (e) In effecting the conversion transactions described in this
Section, the Conversion Agent is acting [as agent of the holders of Preferred
Secuities (in the exchange of Preferred Securities for Debentures) and] as agent
of the Holders of Debentures (in the conversion of Debentures into Common
Stock)[, as the case may be,] directing it to effect such conversion
transactions. The Conversion Agent is hereby authorized [(i) to exchange
Debentures held by the Trust from time to time for Preferred Securities in
connection with the conversion of such Preferred Securities in accordance with
this Article 13 and (ii) [to convert all or a portion of the Debentures into
Common Stock and thereupon to deliver such shares of Common Stock in accordance
with the provisions of this Article 13 [and to deliver to the Trust a new
Debenture or Debentures for any resulting unconverted principal amount.]

          (f) The Company shall at all times reserve and keep available out of
its authorized and unissued Common Stock, solely for issuance upon the
conversion of the Debentures, such number of shares of Common Stock as shall
from time to time be issuable upon the conversion of all the Debentures then
outstanding.  Notwithstanding the foregoing, the Company shall be entitled to
deliver upon conversion of Debentures shares of Common Stock reacquired and held
in the treasury of the Company (in lieu of the issuance of authorized and
unissued shares of Common Stock) so long as any such treasury shares are free
and clear of all liens,

                                      93
<PAGE>

charges, security interests or encumbrances. Whenever the Company issues shares
of Common Stock upon conversion of Debentures and the Company has in effect at
such time a share purchase rights agreement under which holders of Common Stock
are issued rights ("Rights") entitling the holders under certain circumstances
to purchase an additional share or shares of stock, the Company will issue,
together with each such share of Common Stock, such number of Rights (which
number may be a fraction) as shall at that time be issuable with a share of
Common Stock pursuant to such share purchase rights agreement. Any shares of
Common Stock issued upon conversion of the Debentures shall be duly authorized,
validly issued and fully paid and nonassessable. The Conversion Agent shall
deliver the shares of Common Stock received upon conversion of the Debentures to
the converting Holder free and clear of all liens, charges, security interests
and encumbrances, except for United States withholding taxes. The Company shall
use its best efforts to obtain and keep in force such governmental or regulatory
permits or other authorizations as may be required by law, and shall comply with
all applicable requirements as to registration or qualification of the Common
Stock (and all requirements to list the Common Stock issuable upon conversion of
Debentures that are at the time applicable), in order to enable the Company to
lawfully issue Common Stock upon conversion of the Debentures and to lawfully
deliver the Common Stock to each Holder upon conversion of the Debentures.

          (g) The Company will pay any and all taxes that may be payable in
respect of the issue or delivery of shares of Common Stock on conversion of
Debentures.  The Company shall not, however, be required to pay any tax which
may be payable in respect of any transfer involved in the issue and delivery of
shares of Common Stock in a name other than that in which the Debentures so
converted were registered, and no such issue or delivery shall be made unless
and until the Person requesting such issue has paid to the Conversion Agent the
amount of any such tax, or has established to the satisfaction of the Conversion
Agent that such tax has been paid.

          (h) Nothing in this Article 13 shall limit the requirement of the
Company to withhold taxes pursuant to the terms of the Debentures or as set
forth in this Agreement or otherwise require the Trustee or the Company to pay
any amounts on account of such withholdings.

          Section 13.3   Conversion Price Adjustments.  The conversion price
                         ----------------------------
shall be subject to adjustment (without duplication) from time to time as
follows:

                                      94
<PAGE>

          (a) In case the Company shall, while any of the Debentures are
outstanding, (i) pay a dividend or make a distribution with respect to its
Common Stock in shares of Common Stock, (ii) subdivide its outstanding shares of
Common Stock, (iii) combine its outstanding shares of Common Stock into a
smaller number of shares or (iv) issue by reclassification of its shares of
Common Stock any shares of capital stock of the Company, the conversion
privilege and the Conversion Price in effect immediately prior to such action
shall be adjusted so that the Holder of any Debentures thereafter surrendered
for conversion shall be entitled to receive the number of shares of capital
stock of the Company which he would have owned immediately following such action
had such Debentures been converted immediately prior thereto.  An adjustment
made pursuant to this subsection (a) shall become effective immediately after
the record date in the case of a dividend or other distribution and shall
become effective immediately after the effective date in case of a subdivision,
combination or reclassification (or immediately after the record date if a
record date shall have been established for such event).  If, as a result of an
adjustment made pursuant to this subsection (a), the Holder of any Debenture
thereafter surrendered for conversion shall become entitled to receive shares of
two or more classes or series of capital stock of the Company, the Board of
Directors (whose determination shall be conclusive and shall be described in a
Board Resolution filed with the Trustee) shall determine the allocation of the
adjusted Conversion Price between or among shares of such classes or series of
capital stock.  In the event that such dividend, distribution, subdivision,
combination or issuance is not so paid or made, the Conversion Price shall again
be adjusted to be the Conversion Price which would then be in effect if such
record date had not been fixed.

          (b) In case the Company shall, while any of the Debentures are
Outstanding, issue rights or warrants to all holders of its Common Stock
entitling them (for a period expiring within 45 days after the record date
mentioned below) to subscribe for or purchase shares of Common Stock at a price
per share less than the Current Market Price per share of Common Stock on the
record date mentioned below, the Conversion Price for the Debentures shall be
adjusted so that the same shall equal the price determined by multiplying the
Conversion Price in effect immediately prior to the date of issuance of such
rights or warrants by a fraction, the numerator of which shall be the number of
shares of Common Stock outstanding on the date of issuance of such rights or
warrants plus the number of shares which the aggregate offering price of the
total number of shares so offered for subscription or purchase would purchase at
such Current Market Price, and the denominator of which shall be the number of
shares of Common Stock outstanding on the date of issuance of such rights or
warrants plus the number of additional shares of Common

                                      95
<PAGE>

Stock offered for subscription or purchase. Such adjustment shall become
effective immediately after the record date for the determination of
stockholders entitled to receive such rights or warrants. For the purposes of
this subsection, the number of shares of Common Stock at any time outstanding
shall not include shares held in the treasury of the Company. The Company shall
not issue any rights or warrants in respect of shares of Common Stock held in
the treasury of the Company. In case any rights or warrants referred to in this
subsection in respect of which an adjustment shall have been made shall expire
unexercised within 45 days after the same shall have been distributed or issued
by the Company, the Conversion Price shall be readjusted at the time of such
expiration to the Conversion Price that would have been in effect if no
adjustment had been made on account of the distribution or issuance of such
expired rights or warrants.

          (c) Subject to the last sentence of this subparagraph, in case the
Company shall, by dividend or otherwise, distribute to all holders of its Common
Stock evidences of its indebtedness, shares of any class or series of capital
stock, cash or assets (including securities, but excluding any rights or
warrants referred to in subparagraph (b), any dividend or distribution paid
exclusively in cash and any dividend or distribution referred to in subparagraph
(a) of this Section 13.3), the Conversion Price shall be reduced so that the
same shall equal the price determined by multiplying the Conversion Price in
effect immediately prior to the effectiveness of the Conversion Price reduction
contemplated by this subparagraph (c) by a fraction, the numerator of which
shall be the Current Market Price per share of the Common Stock on the date
fixed for the payment of such distribution (the "Reference Date") less the
fair market value (as determined in good faith by the Board of Directors, whose
determination shall be conclusive and described in a resolution of the Board of
Directors), on the Reference Date, of the portion of the evidences of
indebtedness, shares of capital stock, cash and assets so distributed applicable
to one share of Common Stock, and the denominator of which shall be such Current
Market Price per share of the Common Stock, such reduction to become effective
immediately prior to the opening of business on the day following the
Reference Date.  In the event that such dividend or distribution is not so paid
or made, the Conversion Price shall again be adjusted to be the Conversion Price
which would then be in effect if such dividend or distribution had not occurred.
For purposes of this subparagraph (c), any dividend or distribution that
includes shares of Common Stock or rights or warrants to subscribe for or
purchase shares of Common Stock shall be deemed instead to be (i) a dividend or
distribution of the evidences of indebtedness, shares of capital stock, cash or
assets other than such shares of Common Stock or such rights or warrants (making
any Conversion Price reduction required by this

                                      96
<PAGE>

subparagraph (c)) immediately followed by (ii) a dividend or distribution of
such shares of Common Stock or such rights or warrants (making any further
conversion price reduction required by subparagraph (a) or (b)), except (A) the
Reference Date of such dividend or distribution as defined in this subparagraph
shall be substituted as (x) "the record date in the case of a dividend or other
distribution," and (y) "the record date for the determination of stockholders
entitled to receive such rights or warrants" and (z) "the date fixed for such
determination" within the meaning of subparagraphs (a) and (b) and (B) any
shares of Common Stock included in such dividend or distribution shall not be
deemed outstanding for purposes of computing any adjustment of the conversion
price in subparagraph (a).

          (d) In case the Company shall pay or make a dividend or other
distribution on its Common Stock exclusively in cash (excluding all cash
dividends, if the annualized amount thereof per share of Common Stock does not
exceed 12.5% of the Current Market Price per share of the Common Stock on the
trading day immediately preceding the date of declaration of such dividend), the
Conversion Price shall be reduced so that the same shall equal the price
determined by multiplying the Conversion Price in effect immediately prior to
the effectiveness of the Conversion Price reduction contemplated by this
subparagraph (d) by a fraction, the numerator of which shall be the Current
Market Price per share of the Common Stock on the date fixed for the payment of
such distribution less the amount of cash so distributed (excluding that portion
of such distribution that does not exceed 12.5% of the Current Market Price per
share, determined as provided above) applicable to one share of Common Stock and
the denominator of which shall be such Current Market Price per share of the
Common Stock, such reduction to become effective immediately prior to the
opening of business on the day following the date fixed for the payment of such
distribution; provided, however, that in the event the portion of the cash so
              --------  -------
distributed applicable to one share of Common Stock is equal to or greater than
the Current Market Price per share of the Common Stock on the record date
mentioned above (excluding that portion of such distribution that does not
exceed 12.5% of the Current Market Price per share, determined as provided
above), in lieu of the foregoing adjustment, adequate provision shall be made so
that each Holder of shares of Debentures shall have the right to receive upon
conversion the amount of cash such Holder would have received had such Holder
converted each share of the Debentures immediately prior to the record date for
the distribution of the cash (less that portion of such distribution that does
not exceed 12.5% of the Current Market Price per share, determined as provided
above).  In the event that such dividend or distribution is not so paid or made,
the Conversion Price

                                      97
<PAGE>

shall again be adjusted to be the conversion price which would then be in effect
if such record date had not been fixed.

          (e) In case a tender or exchange offer (other than an odd-lot offer)
made by the Company or any Subsidiary of the Company for all or any portion of
the Common Stock shall expire and such tender or exchange offer shall involve
the payment by the Company or such Subsidiary of consideration per share of
Common Stock having a fair market value (as determined in good faith by the
Board of Directors, whose determination shall be conclusive and described in a
resolution of the Board of Directors) at the last time (the "Expiration Time")
tenders or exchanges may be made pursuant to such tender or exchange offer (as
it shall have been amended) that exceeds 110% of the Current Market Price per
share of the Common Stock on the trading day next succeeding the Expiration
Time, the Conversion Price shall be reduced so that the same shall equal the
price determined by multiplying the Conversion Price in effect immediately prior
to the effectiveness of the Conversion Price reduction contemplated by this
subparagraph (e) by a fraction, the numerator of which shall be the number of
shares of Common Stock outstanding (including any tendered or exchanged shares)
at the Expiration Time (including the Purchased Shares) (as defined below)
multiplied by the Current Market Price per share of the Common Stock on the
Trading Day next succeeding the Expiration Time and the denominator of which
shall be the sum of (x) the fair market value (deter  mined as aforesaid) of the
aggregate consideration payable to stockholders based on the acceptance (up to
any maximum specified in the terms of the tender or exchange offer) of all
shares validly tendered or exchanged and not withdrawn as of the Expiration Time
(the shares deemed so accepted, up to any such maximum, being referred to as the
"Purchased Shares") (excluding that portion of such consideration that does not
exceed 110% of the Current Market Price per share) and (y) the product of the
number of shares of Common Stock outstanding (less any Purchased Shares) at the
Expiration Time and the Current Market Price per share of the Common Stock on
the trading day next succeeding the Expiration Time, such reduction to become
effective immediately prior to the opening of business on the day following the
Expiration Time.  In the event that such tender or exchange offer is not so
made, the Conversion Price shall again be adjusted to be the Conversion Price
which would then be in effect if such record date had not been fixed.

          (f) If the distribution date for the Rights of the Company provided in
a share purchase rights agreement occurs prior to the Conversion Date, and a
Holder of the Debentures who converts such Debentures after such distribution
date is not entitled to receive

                                      98
<PAGE>

the Rights that would otherwise be attached (but for the date of conversion) to
the shares of Common Stock received upon such conversion, then an adjustment
shall be made to the Conversion Price pursuant to clause (ii) of Section 13.4(a)
as if the Rights were being distributed to the common stockholders of the
Company immediately prior to such conversion. If such an adjustment is made and
the Rights are later redeemed, invalidated or terminated, then a corresponding
reversing adjustment shall be made to the Conversion Price, on an equitable
basis, to take account of such event.

          (g) The Company shall have the right to reduce from time to time the
Conversion Price by any amount selected by the Company for any period of at
least 30 days, provided, that the Company shall give at least 15 days' notice of
               --------
such reduction to the Trustee [and the Property Trustee]. The Company may, at
its option, make such reductions in the Conversion Price, in addition to those
set forth above in Section 13.4(a), as the Board of Directors deems advisable to
avoid or diminish any income tax to holders of Common Stock resulting from any
dividend or distribution of stock (or rights to acquire stock) or from any event
treated as such for income tax purposes. No adjustment of the Conversion Price
will be made upon the issuance of any shares of Common Stock (or securities
convertible into or exercisable or exchangeable for Common Stock) except as
specifically described above including pursuant to any present or future plan
providing for the reinvestment of dividends or interest payable on securities of
the Company and the investment of additional optional amounts in shares of
Common Stock under any such plan, or the issuance of any shares of Common Stock
or options or rights to purchase such shares pursuant to any present or future
employee benefit plan or program of the Company or pursuant to any option,
warrant, right, or exercisable, exchangeable or convertible security which does
not constitute an issuance to all holders of Common Stock of rights or warrants
entitling holders of such rights or warrants to subscribe for or purchase Common
Stock at less than the Current Market Price. No adjustment in the Conversion
Price will be required unless such adjustment would require an increase or
decrease of at least 1% of the Conversion Price, but any adjustment that would
otherwise be required to be made shall be carried forward and taken into account
in a subsequent adjustment.

          (h) If any action would require adjustment of the Conversion Price
pursuant to more than one of the provisions described above, only one adjustment
shall be made and such adjustment shall be the amount of adjustment that has the
highest absolute value to the Holder of the Debentures.

          Section 13.4   Fundamental Change.  (a)  In the event that the Company
                         ------------------
is a party to any transaction (including, without limitation, a merger other
than a merger that does not result in a reclassification, conversion, exchange
or cancellation of Common Stock), consolidation, sale of all or substantially
all of the assets of the Company, recapitalization or reclassification of Common
Stock (other than a reclassification or recapitalization to which Section
13.3(a) is applicable) or any compulsory share exchange (each of the foregoing
being referred to as a "Transaction"), in each case, as a result of which
shares of Common Stock shall be converted into the right to receive, or shall be
exchanged for, (i) in the case of any Transaction other than a Transaction
involving a Common Stock Fundamental Change (and subject to funds being legally
available for such purpose under applicable law at the time of such conversion),
securities, cash or other property, each Debenture shall thereafter be
convertible into the kind and, in the case of a Transaction which does not
involve a Fundamental Change, amount of securities, cash and other property
receivable upon the consummation of such Transaction by a holder of that number
of shares of Common Stock into which a Debenture was convertible immediately
prior to such Transaction, or (ii) in the case of a Transaction involving a
Common Stock Fundamental Change, common stock, each Debenture shall thereafter
be convertible (in the manner described herein) into common stock of the kind
received by holders of Common Stock (but in each case after giving effect to any
adjustment discussed in paragraphs (b) and (c) relating to a Fundamental Change
if such Transaction constitutes a Fundamental Change). The holders of
Debentures or Preferred Securities will have no voting rights with respect to
any Transaction described in this section.

               (b)  If any Fundamental Change occurs, then the Conversion Price
in effect will be adjusted immediately after such Fundamental Change as
described in paragraph (c) below. In addition, in the event of a Common Stock
Fundamental Change, each Debenture shall be convertible solely into common stock
of the kind received by holders of Common Stock as a result of such Common Stock
Fundamental Change.

               (c)  The Conversion Price in the case of any Transaction
involving a Fundamental Change will be adjusted immediately after such
Fundamental Change:

                    (1)  in the case of a Non-Stock Fundamental Change, the
          Conversion Price of the Debentures will thereupon become the lower of
          (A) the Conversion Price in effect immediately prior to such Non-Stock
          Fundamental Change, but after giving effect

                                      100
<PAGE>

          to any other prior adjustments, and (B) the result obtained by multi
          plying the greater of the Applicable Price or the then applicable
          Reference Market Price by a fraction, the numerator of which will be
          $50 and the denominator of which will be (x) the amount of the
          redemption price for each $50 aggregate principal amount of Debentures
          if the redemption date were the date of such Non-Stock Fundamental
          Change (or, for the period commencing on the first date of original
          issuance of the Debentures and through __________, 20__, and the
          twelve-month periods commencing __________, 20__ and __________, 20__,
          the product of _____%, _____% and ______%, respectively, multiplied by
          $50) plus (y) any then-accrued and unpaid interest on the Debentures;
          and

                    (2)  in the case of a Common Stock Fundamental Change, the
          Conversion Price of the Debentures in effect immediately prior to such
          Common Stock Fundamental Change, but after giving effect to any other
          prior adjustments, will thereupon be adjusted by multiplying such
          Conversion Price by a fraction, the numerator of which will be the
          Purchaser Stock Price and the denominator will be the Applicable
          Price; provided, however, that in the event of a Common Stock
          Fundamental Change in which (A) 100% of the value of the consideration
          received by a holder of Common Stock is common stock of the successor,
          acquiror, or other third party (and cash, if any, is paid only with
          respect to any fractional interests in such common stock resulting
          from such Common Stock Fundamental Change) and (B) all of the Common
          Stock will have been exchanged for, converted into, or acquired for
          common stock (and cash with respect to fractional interests) of the
          successor, acquiror, or other third party, the Conversion Price of the
          Debentures in effect immediately prior to such Common Stock
          Fundamental Change will thereupon be adjusted by multiplying such
          Conversion Price by a fraction, the numerator of which will be one and
          the denominator of which will be the number of shares of common stock
          of the successor, acquiror, or other third party received by a holder
          of one share of Common Stock as a result of such Common Stock
          Fundamental Change.

          Section 13.5   Notice of Adjustments of Conversion Price.  Whenever
                         -----------------------------------------
the Conversion Price is adjusted as herein provided:

<PAGE>

               (a)  the Company shall compute the adjusted Conversion Price and
shall prepare a certificate signed by the Chief Financial Officer or the
Treasurer of the Company setting forth the adjusted Conversion Price and showing
in reasonable detail the facts upon which such adjustment is based, and such
certificate shall forthwith be filed with the Trustee, the Conversion Agent and
the transfer agent for the Preferred Securities and the Debentures; and

               (b)  a notice stating the Conversion Price has been adjusted and
setting forth the adjusted Conversion Price shall as soon as practicable be
mailed by the Company to all record holders of Preferred Securities and the
Debentures at their last addresses as they appear upon the stock transfer books
of the Company and the Trust and the Securities Registrar.

          Section 13.6   Prior Notice of Certain Events.
                         ------------------------------

          In case:

                         (i)   the Company shall (A) declare any dividend (or
     any other distribution) on its Common Stock, other than (x) a dividend
     payable in shares of Common Stock or (y) a dividend payable in cash that
     would not require an adjustment pursuant to Section 13.4(c) or (d) or (B)
     authorize a tender or exchange offer that would require an adjustment
     pursuant to Section 13.4(e);

                         (ii)  the Company shall authorize the granting to all
     holders of Common Stock of rights or warrants to subscribe for or purchase
     any shares of stock of any class or series or of any other rights or
     warrants;

                         (iii) of any reclassification of Common Stock (other
     than a subdivision or combination of the outstanding Common Stock, or a
     change in par value, or from par value to no par value, or from no par
     value to par value), or of any consolidation or merger to which the Company
     is a party and for which approval of stockholders of the Company shall be
     required, or of the sale or transfer of all or substantially all of the
     assets of the Company or of any compulsory share exchange whereby the
     Common Stock is converted into other securities, cash or other property;
     or

                         (iv)  of the voluntary or involuntary dissolution,
     liquidation or winding up of the Company;

                                      102
<PAGE>

then the Company shall [(A) if any Preferred Securities are outstanding under
the Trust Agreement, cause to be filed with the transfer agent for the Preferred
Securities, and shall cause to be mailed to the holders of record of the
Preferred Securities, at their last addresses as they shall appear upon the
stock transfer books of the Trust or (B)] cause to be mailed to all Holders at
their last addresses as they shall appear in the Security Register, at least 15
days prior to the applicable record or effective date hereinafter specified, a
notice stating (x) the date on which a record (if any) is to be taken for the
purpose of such dividend, distribution, rights or warrants or, if a record is
not to be taken, the date as of which the holders of Common Stock of record to
be entitled to such dividend, distribution, rights or warrants are to be
determined or (y) the date on which such reclassification, consolidation,
merger, sale, transfer, share exchange, dissolution, liquidation or winding up
is expected to become effective, and the date as of which it is expected that
holders of Common Stock of record shall be entitled to exchange their shares of
Common Stock for securities, cash or other property deliverable upon such
reclassification, consolidation, merger, sale, transfer, share exchange,
dissolution, liquidation or winding up (but no failure to mail such notice or
any defect therein or in the mailing thereof shall affect the validity of the
corporate action required to be specified in such notice).

          Section 13.7   Dividend or Interest Reinvestment Plans.
                         ---------------------------------------
Notwithstanding anything to the contrary in this Article 13, the issuance of any
shares of Common Stock pursuant to any plan providing for the reinvestment of
dividends or interest payable on securities of the Company and the investment of
additional optional amounts in shares of Common Stock under any such plan, and
the issuance of any shares of Common Stock or options or rights to purchase such
shares pursuant to any employee benefit plan or program of the Company or
pursuant to any option, warrant, right or exercisable, exchangeable or
convertible security outstanding as of the date the Debentures were first
issued, shall not be deemed to constitute an issuance of Common Stock or
exercisable, exchangeable or convertible securities by the Company to which any
of the adjustment provisions described above applies. There shall also be no
adjustment of the Conversion Price in case of the issuance of any stock (or
securities convertible into or exchangeable for stock) of the Company except as
specifically described in this Article 13.

          Section 13.8   Certain Additional Rights.  In case the Company shall,
                         -------------------------
by dividend or otherwise, declare or make a distribution on its Common Stock
referred to in Section 13.4(c) or 13.4(d) (including, without limitation,
dividends or distributions referred to in the last sentence of Section 13.4(c)),
the Holders of the

                                      103
<PAGE>

Debentures, upon the conversion thereof subsequent to the close of business on
the date fixed for the determination of stockholders entitled to receive such
distribution and prior to the effectiveness of the Conversion Price adjustment
in respect of such distribution, shall also be entitled to receive for each
share of Common Stock into which the Debentures are converted, the portion of
the shares of Common Stock, rights, warrants, evidences of indebtedness, shares
of capital stock, cash and assets so distributed applicable to one share of
Common Stock; provided, however, that, at the election of the Company (whose
              --------  -------
election shall be evidenced by a resolution of the Board of Directors) with
respect to all Holders so converting, the Company may, in lieu of distributing
to such Holder any portion of such distribution not consisting of cash or
securities of the Company, pay such Holder an amount in cash equal to the fair
market value thereof (as determined in good faith by the Board of Directors,
whose determination shall be conclusive and described in a resolution of the
Board of Directors). If any conversion of Debentures described in the
immediately preceding sentence occurs prior to the payment date for a
distribution to holders of Common Stock which the Holder of Debentures so
converted is entitled to receive in accordance with the immediately preceding
sentence, the Company may elect (such election to be evidenced by a resolution
of the Board of Directors) to distribute to such Holder a due bill for the
shares of Common Stock, rights, warrants, evidences of indebtedness, shares of
capital stock, cash or assets to which such Holder is so entitled, provided,
                                                                   --------
that such due bill (i) meets any applicable requirements of the principal
national securities exchange or other market on which the Common Stock is then
traded and (ii) requires payment or delivery of such shares of Common Stock,
rights, warrants, evidences of indebtedness, shares of capital stock, cash or
assets no later than the date of payment or delivery thereof to holders of
shares of Common Stock receiving such distribution.

          Section 13.9   Trustee Not Responsible for Determining Conversion
                         --------------------------------------------------
Price or Adjustments.  Neither the Trustee nor any Conversion Agent shall at any
- --------------------
time be under any duty or responsibility to any Holder of any Debenture [or to
any holder of a Preferred Security] to determine whether any facts exist which
may require any adjustment of the Conversion Price, or with respect to the
nature or extent of any such adjustment when made, or with respect to the method
employed, or herein or in any supplemental indenture provided to be employed, in
making the same.  Neither the Trustee nor any Conversion Agent shall be
accountable with respect to the validity or value (or the kind of account) of
any shares of Common Stock or of any securities or property, which may at any
time be issued or delivered upon the conversion of any Debenture; and neither
the Trustee nor any Conversion Agent makes any representation with respect
thereto.  Neither the Trustee nor any

                                      104
<PAGE>

Conversion Agent shall be responsible for any failure of the Company to make any
cash payment or to issue, transfer or deliver any shares of Common Stock or
stock certificates or other securities or property upon the surrender of any
Debenture for the purpose of conversion, or, except as expressly herein
provided, to comply with this Article 13.]

                            ARTICLES OF ASSOCIATION


For the purpose of organizing an Association to perform any lawful activities of
a national  bank, the undersigned do enter into the following Articles of
Association:

FIRST.  The title of this Association shall be Chase Manhattan Trust Company,
National Association (the "Association").

SECOND.  The main office of the Association shall be in the City of Pittsburgh,
County of Allegheny, Commonwealth of Pennsylvania.  The business of the
Association shall be limited to the fiduciary powers and the support of
activities incidental to the exercise of those powers.  The Association will
obtain the prior written approval of the Office of the Comptroller of the
Currency before amending these Articles of Association to expand the scope of
its activities and services.

THIRD.  The board of directors of this Association shall consist of not less
than five nor more than twenty-five persons, the exact number to be fixed and
determined from time to time by resolution of a majority of the full board of
directors or by resolution of a majority of the shareholders at any annual or
special meeting thereof.  Each director, during the full term of his
directorship, shall own common or preferred stock of the Association or of a
holding company owning the Association, with an aggregate par, fair market or
equity value of not less than $1,000.  Any vacancy in the board of directors may
be filled by action of the shareholders or a majority of the remaining
directors.

Terms of directors, including directors selected to fill vacancies, shall expire
at the next regular meeting of shareholders at which directors are elected,
unless the directors resign or are removed from office.

Despite the expiration of a director's term, the director shall continue to
serve until his or her successor is elected and qualifies or until there is a
decrease in the number of directors and his or her position is eliminated.

FOURTH.  There shall be an annual meeting of the shareholders to elect directors
and transact whatever other business may be brought before the meeting.  It
shall be held at the main office or any other convenient place the board of
directors may designate, on the day of each year specified therefore in the by-
laws, or if that day falls on a legal holiday in the state in which the
Association is located, on the next following banking day.  If no election is
held on the day fixed or in event of a legal holiday, on the following banking
day, an election may be held on any subsequent day within 60 days of the day
fixed, to be designated by the board of directors, or, if the directors fail to
fix the day, by shareholders representing two-thirds of the shares issued and
outstanding.  Advance notice of the meeting may be duly waived by the sole
shareholder in accordance with 12 C.F.R. 7.2001.

A director may resign at any time by delivering written notice to the board of
directors, its Chairperson, or to the Association, which resignation shall be
effective when the notice is delivered unless the notice specifies a later

Re:  Change in Corporate Title
       New Trust Company, National Association (Bank)
       Pittsburgh, Pennsylvania

Dear Mr. Bielawa:

The Office of the Comptroller of the Currency (OCC) has received your
submission, concerning the change and amendment to Article First of the above-
referenced Bank's Articles of Association. The OCC has amended its records to
reflect that effective November 24, 1997, the corporate title of New Trust
Company, National Association, Charter Number 23548, was changed to "Chase
Manhattan Trust Company, National Association."

You are reminded that the OCC does not approve national bank name changes nor
dies it maintain official titles or the retention of alternate titles. The use
of other titles or the retention of the rights o any previously title is the
responsibility of the Bank's board of directors. Legal counsel should be
consulted to determine whether or not the new title, or any previously used
title, could be challenged by competing institutions under the provisions of
federal state law.

A copy of the amended Article as accepted for filing is enclosed for the Bank's
records.

Very truly yours

Re:  Charter for a National Trust Bank, New Trust Company, National Association.
     Pittsburgh, Pennsylvania
     ACN 97 NE 01 0022

Dear Mr. Zupan:

The Comptroller of the Currency (OCC) has found that you have met all conditions
imposed by the OCC and completed all steps necessary to commence the business of
banking.  Your charter certificate is enclosed.  You are authorized to commence
business on November 24, 1997.

This letter also constitutes OCC authorization to exercise fiduciary powers.

You are reminded that several of the standard conditions contained in the
preliminary approval letter dated October 23, 1997 will continue to apply once
the bank opens and by opening, you agree to subject your association to these
conditions of operations. Some of the conditions bear reiteration here:

1.   Regardless of the association's FDIC insurance status, the association is
     subject to the Change in Bank Control act (12 U.S.C. 1817(j)) by virtue of
     its national bank charter. Please refer to item 4 in the list of standard
     conditions sent with the preliminary approval letter.

2.   The board of directors is responsible for regular review and update of
     policies and procedures and for assuring ongoing compliance with them. This
     includes maintaining an internal control system that ensures compliance
     with the currency reporting and record keeping requirements of the Bank
     Secrecy Act (BSA). The board is expected to train its personnel in BSA
     procedures and designate one person or a group to monitor day-to-day
     compliance.

                                       8

3.  The bank will not engage in full commercial powers authorized to national
    banks without the OCC's prior approval

Following the commencement of operations, bank management is urged to become
familiar with the requirements of the Securities Exchange Act of 1934 and Part
11 of the Comptroller's regulations relative to the registration of the bank's
equity securities and related periodic reports.  These requirements will be
applicable to your bank when the number of shareholders of record is maintained
at 500 or more.  Such registration may be  subsequently terminated pursuant to
the Act, only when the number of shareholders of record is reduced to fewer than
300.

Should you have any questions regarding the supervision of your bank, please
contact the portfolio manager who will be responsible for OCC's ongoing
supervisory effort at your institution.  You will be notified of the name and
number of the appropriate individual in the near future.

Sincerely,

/s/ Micheal G. Tiscia

the shareholders at any meeting, unless otherwise provided by law or by the
Articles of Association, or by the shareholders or directors pursuant to Section
10.2.  Any action required or permitted to be taken by the shareholders may be

matter, funds held pursuant to such instrument shall be invested in investments
in which corporate fiduciaries may invest under applicable law.

Section 5.3.  Trust Audit Committee.  The board shall appoint a committee of at
least two directors, exclusive of any active officer of the association, which
shall, at least once during each calendar year make suitable audits of the
association's fiduciary activities or cause suitable audits to be made by
auditors responsible only to the board, and at such time shall ascertain whether
fiduciary powers have been administered according to law, Part 9 of the

Article VI. Stock and Stock Certificates

Section 6.1.  Transfers.  Shares of stock shall be transferable on the books of
the Association, and a transfer book shall be kept in which all transfers of
stock shall be recorded.  Every person becoming a shareholder by such transfer
shall, in proportion to his or her shares, succeed to all rights of the prior
holder of such shares. The board may impose conditions upon the transfer of the
stock reasonably calculated to simplify the work of the Association with respect
to stock transfers, voting at shareholder meetings, and related matters and to
protect it against fraudulent transfers.

Section 6.2.  Stock Certificates.  Certificates of stock shall bear the
signature of the Chairperson or Co-Chairpersons of the board or President (which
may be engraved, printed or impressed), and shall be signed manually or by
facsimile process by the Secretary, Assistant Secretary, Cashier, Assistant
Cashier, or any other officer appointed by the board for that purpose, to be
known as an authorized officer, and the seal of the Association shall be
engraved thereon.  Each certificate shall recite on its face that the stock
represented thereby is transferable only upon the books of the Association
properly endorsed.  In case any such officer who has signed or whose facsimile
signature has been placed upon such certificate shall have ceased to be such
before such certificate is issued, it may be issued by the Association with the
same effect as if such officer had not ceased to be such at the time of its
issue.  The corporate seal may be a facsimile, engraved or printed.

Secretary or any Assistant Cashier or Assistant Secretary, or other officer
thereunto designated by the board, shall have authority to affix the corporate

President, or any Assistant Vice President, or the Chief Financial Officer, or
the Controller, or the Secretary, or the Cashier, or, if in connection with

any Trust Officer.  Any such instruments may also be executed, acknowledged,
verified, delivered or accepted on behalf of the Association in such other
manner and by such other officers as the board may from time to time direct.
The provisions of this Section 8.2 are supplementary to any other provision of
these by-laws.

Section 8.3.  Records.  The Articles of Association, the by-laws and the
proceedings of all meetings of the shareholders, the board, and standing

for that purpose.  The minutes of each meeting shall be signed by the Secretary,
Cashier or other officer appointed to act as Secretary of the meeting.

with applicable Federal banking law, bank safety and soundness or these by-laws,

                         Article IX.  Indemnification

Section 9.1.  Right to Indemnification.  Each person who was or is made a party
or is threatened to be made a party to or is otherwise involved in any action,
suit or proceeding, whether civil, criminal, administrative or investigative
(hereinafter a "proceeding"), by reason of the fact that he or she is or was a
director or an officer of the Association or is or was serving at the request of
the Association as a director, officer, employee or agent of another corporation
or of a partnership, joint venture, trust or other enterprise, including service
with respect to an employee benefit plan (hereinafter an "indemnitee"), whether
the basis of such proceeding is alleged action in an official capacity as a
director, officer, employee or agent or in any other capacity while serving as a
director, officer, employee or agent, shall be indemnified and held harmless by
the Association to the fullest extent authorized by the Delaware General
Corporation Law, as the same exists or may hereafter be amended (but, in the
case of any such amendment, only to the extent that such amendment permits the
Association to provide broader indemnification rights than such law permitted
the Association to provide prior to such amendment), against all expense,
liability and loss (including attorneys' fees, judgments, fines, ERISA excise
taxes or penalties and amounts paid in settlement) reasonably incurred or
suffered by such indemnitee in connection therewith; provided, however, that,
except as provided in Section 9.3 of these by-laws with respect to proceedings
to enforce rights to indemnification, the Association shall indemnify any such
indemnitee in connection with a proceeding (or part thereof) initiated by such
indemnitee only if such proceeding (or part thereof) was authorized by the
board.


Section 9.2.  Right to Advancement of Expenses.  The right to indemnification
conferred in Section 9.1 of these by-laws shall include the right to be paid by
the Association the expenses (including attorney's fees) incurred in defending
any such proceeding in advance of its final disposition (hereinafter an
"advancement of expenses"); provided, however, that, if the Delaware General
Corporation Law requires, an advancement of expenses incurred by an indemnitee
in his or her capacity as a director or officer (and not in any other capacity
in which service was or is rendered by such indemnitee, including, without
limitation, service to an employee benefit plan) shall be made only upon
delivery to the Association of an undertaking (hereinafter an "undertaking"), by
or on behalf of such indemnitee, to repay all amounts so advanced if it shall
ultimately be determined by final judicial decision from which there is no
further right to appeal (hereinafter a "final adjudication") that such
indemnitee is not entitled to be indemnified for such expenses under this
Section 9.2 or otherwise.  The rights to

                                      14
<PAGE>

indemnification and to the advancement of expenses conferred in Sections 9.1 and
9.2 of these by-laws shall be contract rights and such rights shall continue as
to an indemnitee who has ceased to be a director, officer, employee or agent and
shall inure to the benefit of the indemnities heirs, executors and
administrators.

Section 9.3.  Right of Indemnitee to Bring Suit.  If a claim under Section 9.1
or 9.2 of these by-laws is not paid in full by the Association within sixty (60)
days after a written claim has been received by the Association except in the
case of a claim for an advancement of expenses, in which case the applicable
period shall be twenty (20) days, the indemnitee may at any time thereafter
bring suit against the Association to recover the unpaid amount of the claim.
If successful in whole or in part in any such suit, or in a suit brought by the
Association to recover an advancement of expenses pursuant to the terms of an
undertaking, the indemnitee shall be entitled to be paid also the expense  of
prosecuting or defending such suit.  In (1) any suit brought by the indemnitee
to enforce a right to indemnification hereunder (but not in a suit brought by
the indemnitee to enforce a right to an advancement of expenses) it shall be a
defense that, and (2) any suit brought by the Association to recover an
advancement of expenses pursuant to the terms of an undertaking, the Association
shall be entitled to recover such expenses upon a final adjudication that, the
indemnitee has not met any applicable standard for indemnification set forth in
the Delaware General Corporation Law.  Neither the failure of the Association
(including the board, the Association's independent legal counsel, or its
shareholders) to have made a determination prior to the commencement of such
suit that indemnification of the indemnitee is proper in the circumstances
because the indemnitee has met the applicable standard of conduct set forth in
the Delaware General Corporation Law, nor an actual determination by the
Association (including the board, the Association's independent legal counsel,
or its shareholders) that the indemnitee has not met such applicable standard of
conduct, shall create a presumption that the indemnitee has not met the
applicable standard of conduct or, in the case of such a suit brought by the
indemnitee, be a defense to such suit.  In any suit brought by the indemnitee to
enforce a right to indemnification or to an advancement of expenses hereunder,
or brought by the Association to recover an advancement of expenses pursuant to
the terms of an undertaking, the burden of proving that the indemnitee is not
entitled to be indemnified, or to such advancement of expenses, under this
Article IX or otherwise shall be on the Association.

Section 9.4.  Non-Exclusivity of Rights.  The rights to indemnification and to
the advancement of expenses conferred in this Article IX shall not be exclusive
of any other right which any person may have or hereafter acquire under any
statute, the Association's Articles of Association, by-laws, agreement, vote of
shareholders or disinterested directors or otherwise.

Section 9.5.  Insurance.  The Association may maintain insurance, at its
expense, to protect itself and any director, officer, employee or agent of the
Association or another corporation, partnership, joint venture, trust or other
enterprise against any expense, liability or loss, whether or not the
Association would have the power to indemnify such person against such expense,
liability or loss under the Delaware General Corporation Law.

Section 9.6.  Indemnification of Employees and Agents of the Association.  The
Association may, to the extent authorized from time to time by the board, grant
rights to indemnification and to the advancement of expenses to any employee or
agent of the Association to the fullest extent of the provisions of this Article
IX with respect to the indemnification and advancement of expenses of directors
and officers of the Association.

                              Article X.  By-laws

Section 10.1.  Inspection.  A copy of the by-laws, with all amendments, shall at
all times be kept in a convenient place at the main office of the Association,
and shall be open for inspection to all shareholders during banking hours.

Section 10.2.  Amendments.  The by-laws may be amended, altered or repealed, at
any regular meeting of the board by a vote of a majority of the total number of
the directors except as provided below.  The Association's shareholders may
amend or repeal the by-laws even though the by-laws may be amended or repealed
by its board.

                            ARTICLES OF ASSOCIATION


For the purpose of organizing an Association to perform any lawful activities of
a national  bank, the undersigned do enter into the following Articles of
Association:

FIRST.  The title of this Association shall be Chase Manhattan Trust Company,
National Association (the "Association").

SECOND.  The main office of the Association shall be in the City of Pittsburgh,
County of Allegheny, Commonwealth of Pennsylvania.  The business of the
Association shall be limited to the fiduciary powers and the support of
activities incidental to the exercise of those powers.  The Association will
obtain the prior written approval of the Office of the Comptroller of the
Currency before amending these Articles of Association to expand the scope of
its activities and services.

THIRD.  The board of directors of this Association shall consist of not less
than five nor more than twenty-five persons, the exact number to be fixed and
determined from time to time by resolution of a majority of the full board of
directors or by resolution of a majority of the shareholders at any annual or
special meeting thereof.  Each director, during the full term of his
directorship, shall own common or preferred stock of the Association or of a
holding company owning the Association, with an aggregate par, fair market or
equity value of not less than $1,000.  Any vacancy in the board of directors may
be filled by action of the shareholders or a majority of the remaining
directors.

Terms of directors, including directors selected to fill vacancies, shall expire
at the next regular meeting of shareholders at which directors are elected,
unless the directors resign or are removed from office.

Despite the expiration of a director's term, the director shall continue to
serve until his or her successor is elected and qualifies or until there is a
decrease in the number of directors and his or her position is eliminated.

FOURTH.  There shall be an annual meeting of the shareholders to elect directors
and transact whatever other business may be brought before the meeting.  It
shall be held at the main office or any other convenient place the board of
directors may designate, on the day of each year specified therefore in the by-
laws, or if that day falls on a legal holiday in the state in which the
Association is located, on the next following banking day.  If no election is
held on the day fixed or in event of a legal holiday, on the following banking
day, an election may be held on any subsequent day within 60 days of the day
fixed, to be designated by the board of directors, or, if the directors fail to
fix the day, by shareholders representing two-thirds of the shares issued and
outstanding.  Advance notice of the meeting may be duly waived by the sole
shareholder in accordance with 12 C.F.R. 7.2001.

A director may resign at any time by delivering written notice to the board of
directors, its Chairperson, or to the Association, which resignation shall be
effective when the notice is delivered unless the notice specifies a later
effective date.

A director may be removed by shareholders at a meeting called to remove him or
her, when notice of the meeting stating that the purpose or one of the purposes
is to remove him or her is provided, if there is a failure to fulfill one of the
affirmative requirements for qualification, or for cause.

FIFTH.  The authorized amount of capital stock of this Association shall be five
million dollars ($5,000,000), divided into fifty thousand (50,000) shares of
common stock of the par value of one hundred dollars ($ 100) each; but said
capital stock may be increased or decreased from time to time, according to the
provisions of the laws of the United States.

No holder of shares of the capital stock of any class of the Association shall
have any preemptive or preferential right of subscription to any shares of any
class of stock of the Association, whether now or hereafter authorized, or to
any obligations convertible into stock of the

                                       4
<PAGE>

Association, issued, or sold, nor any right to subscription to any thereof other
than such, if any, as the board of directors, in its discretion may from time to
time determine and at such price as the board of directors may from time to time
fix.

Unless otherwise specified in the Articles of Association or required by law,
(1) all matters requiring shareholder action, including amendments to the
Articles of Association, must be approved by shareholders owning a majority
voting interest in the outstanding voting stock, and (2) each shareholder shall
be entitled to one vote per share.

The Association, at any time and from time to time, may authorize and issue debt
obligations, whether or not subordinated, without the approval of the
shareholders.

SIXTH.  The board of directors may appoint one of its members President of this
Association, and one of its members Chairperson of the board or two of its
members as Co-Chairpersons of the board, and shall have the power to appoint one
or more Vice Presidents, a Secretary who shall keep minutes of the directors'
and shareholders' meetings and be responsible for authenticating the records of
the Association, and such other officers and employees as may be required to
transact the business of this Association.  A duly appointed officer may appoint
one or more officers or assistant officers if authorized by the board of
directors in accordance with the by-laws.

The board of directors shall have the power to:
(1)  Define the duties of the officers, employees, and agents of the
Association.
(2)  Delegate the performance of its duties, but not the responsibility for its
duties, to the officers, employees, and agents of the Association.
(3)  Fix the compensation and enter into employment contracts with its officers
and employees upon reasonable terms and conditions consistent with applicable
law.
(4)  Dismiss officers and employees.
(5)  Require bonds from officers and employees and fix the penalty thereof.
(6)  Ratify written policies authorized by the Association's management or
committees of the board.
(7)  Regulate the manner in which any increase or decrease of the capital of the

of shareholders to increase or decrease the capital of the Association in
accordance with law.
(8)  Manage and administer the business and affairs of the Association.
(9)  Adopt initial by-laws, not inconsistent with law or the Articles of
Association, for managing the business and regulating the affairs of the

(11)  Make contracts.
(12) Generally perform all acts that are legal for a board of directors to
perform.

SEVENTH.  The board of directors shall have the power to change the location of
the main office to any other location permitted under applicable law, without
the approval of the shareholders, and shall have the power to establish or
change the location of any branch or branches of the Association to any other
location permitted under applicable law, without the approval of the
shareholders subject to approval by the Office of the Comptroller of the
Currency.

EIGHTH.  The corporate existence of this Association shall continue until
termination according to the laws of the United States.

NINTH. These Articles of Association may be amended at any regular or special
meeting of the shareholders by the affirmative vote of the holders of a majority
of the stock of this Association, unless the vote of the holders of a greater
amount of stock is required by law, and in that case by the vote of the holders
of such greater amount. The Association's board of directors may propose one or
more amendments to the Articles of Association for submission to the
shareholders.

Re:  Change in Corporate Title
       New Trust Company, National Association (Bank)
       Pittsburgh, Pennsylvania

Dear Mr. Bielawa:

The Office of the Comptroller of the Currency (OCC) has received your
submission, concerning the change and amendment to Article First of the above-
referenced Bank's Articles of Association. The OCC has amended its records to
reflect that effective November 24, 1997, the corporate title of New Trust
Company, National Association, Charter Number 23548, was changed to "Chase
Manhattan Trust Company, National Association."

You are reminded that the OCC does not approve national bank name changes nor
dies it maintain official titles or the retention of alternate titles. The use
of other titles or the retention of the rights o any previously title is the
responsibility of the Bank's board of directors. Legal counsel should be
consulted to determine whether or not the new title, or any previously used
title, could be challenged by competing institutions under the provisions of
federal state law.

A copy of the amended Article as accepted for filing is enclosed for the Bank's
records.

Very truly yours

Re:  Charter for a National Trust Bank, New Trust Company, National Association.
     Pittsburgh, Pennsylvania
     ACN 97 NE 01 0022

Dear Mr. Zupan:

The Comptroller of the Currency (OCC) has found that you have met all conditions
imposed by the OCC and completed all steps necessary to commence the business of
banking.  Your charter certificate is enclosed.  You are authorized to commence
business on November 24, 1997.

This letter also constitutes OCC authorization to  exercise fiduciary powers.

You are reminded that  several of the standard conditions contained in the
preliminary approval letter dated October 23, 1997 will continue to apply once
the bank opens and by opening, you agree to subject your association to these
conditions of operations.  Some of the conditions bear reiteration here:

1.   Regardless of the association's FDIC insurance status, the association is
     subject to the Change in Bank Control act (12 U.S.C. 1817(j)) by virtue of
     its national bank charter. Please refer to item 4 in the list of standard
     conditions sent with the preliminary approval letter.

2.   The board of directors is responsible for regular review and update of
     policies and procedures and for assuring ongoing compliance with them. This
     includes maintaining an internal control system that ensures compliance
     with the currency reporting and record keeping requirements of the Bank
     Secrecy Act (BSA). The board is expected to train its personnel in BSA
     procedures and designate one person or a group to monitor day-to-day
     compliance.

                                       8

3.   The bank will not engage in full commercial powers authorized to national
     banks without the OCC's prior approval

Following the commencement of operations, bank management is urged to become
familiar with the requirements of the Securities Exchange Act of 1934 and Part
11 of the Comptroller's regulations relative to the registration of the bank's
equity securities and related periodic reports.  These requirements will be
applicable to your bank when the number of shareholders of record is maintained
at 500 or more.  Such registration may be  subsequently terminated pursuant to
the Act, only when the number of shareholders of record is reduced to fewer than
300.

Should you have any questions regarding the supervision of your bank, please
contact the portfolio manager who will be responsible for OCC's ongoing
supervisory effort at your institution.  You will be notified of the name and
number of the appropriate individual in the near future.

Sincerely,

/s/ Micheal G. Tiscia

majority of the votes cast shall decide every question or matter submitted to
the shareholders at any meeting, unless otherwise provided by law or by the
Articles of Association, or by the shareholders or directors pursuant to Section
10.2.  Any action required or permitted to be taken by the shareholders may be

than twenty-five persons, the exact number within such minimum and maximum

                 --------- --------
increase the number of directors to a number which:  (1) exceeds by more than
two the number of directors last elected by shareholders where such number was
15 or less; and (2) exceeds by more than four the number of directors last

special meeting at least one day prior to such meeting.  Any business may be
transacted at any special meeting.

Section 2.6.  Action by the Board.  Except as otherwise provided by law,
corporate action to be taken by the board shall mean such action at a meeting of

of the board or any committee may participate in a meeting of the board or

the Articles of Association or these by-laws, a majority of the directors shall
constitute a quorum for the transaction of any business at any meeting of the

be given.  At any such adjourned meeting at which a quorum is present, any

the event of a vacancy in the board for any other cause, a director may be
appointed to fill such vacancy by vote of a majority of the remaining directors
then in office.

the authority and direction of the board and shall report to it when required.

Section 5.1.  Trust Committee.  There shall be a Trust Committee of this
Association composed of four or more members, who shall be capable and
experienced officers or directors of the Association.  The Committee is charged
with the responsibility for the investment, retention, or disposition of assets
held in accounts with respect to which the Association has investment authority;
for the review of the assets of accounts for which the Association has
investment authority promptly after the acceptance of such an account and at
least once during every calendar year thereafter to determine the advisability
of retaining or disposing of such assets; for the determination of the manner in
which proxies received for accounts for which the Association has responsibility
for the voting of proxies shall be voted; for the determination of all
substantial questions involving discretionary authority of the Association of a
non-investment nature, including, but not limited to, distribution of principal
and/or income in respect of any account; for providing advice as to the
investment, retention, or disposition of assets in investment advisory accounts
maintained by the Association; for the making of such reports as this board

conditions as the Committee may from time to time prescribe.

Section 5.2.  Trust Investments.  Funds held in a fiduciary capacity shall be
invested according to the instrument establishing the fiduciary relationship and
local law.  Where such instrument does not specify the character and class of

in which corporate fiduciaries may invest under applicable law.

Section 5.3.  Trust Audit Committee.  The board shall appoint a committee of at
least two directors, exclusive of any active officer of the association, which
shall, at least once during each calendar year make suitable audits of the

been properly undertaken and discharged.


Article VI. Stock and Stock Certificates

Section 6.1.  Transfers.  Shares of stock shall be transferable on the books of
the Association, and a transfer book shall be kept in which all transfers of
stock shall be recorded.  Every person becoming a shareholder by such transfer
shall, in proportion to his or her shares, succeed to all rights of the prior
holder of such shares. The board may impose conditions upon the transfer of the
stock reasonably calculated to simplify the work of the Association with respect
to stock transfers, voting at shareholder meetings, and related matters and to
protect it against fraudulent transfers.

Section 6.2.  Stock Certificates.  Certificates of stock shall bear the
signature of the Chairperson or Co-Chairpersons of the board or President (which
may be engraved, printed or impressed), and shall be signed manually or by
facsimile process by the Secretary, Assistant Secretary, Cashier, Assistant
Cashier, or any other officer appointed by the board for that purpose, to be
known as an authorized officer, and the seal of the Association shall be
engraved thereon.  Each certificate shall recite on its face that the stock
represented thereby is transferable only upon the books of the Association
properly endorsed.  In case any such officer who has signed or whose facsimile
signature has been placed upon such certificate shall have ceased to be such
before such certificate is issued, it may be issued by the Association with the
same effect as if such officer had not ceased to be such at the time of its
issue.  The corporate seal may be a facsimile, engraved or printed.

verified, delivered or accepted on behalf of the Association in such other
manner and by such other officers as the board may from time to time direct.

                         Article IX.  Indemnification

Section 9.1.  Right to Indemnification.  Each person who was or is made a party
or is threatened to be made a party to or is otherwise involved in any action,
suit or proceeding, whether civil, criminal, administrative or investigative
(hereinafter a "proceeding"), by reason of the fact that he or she is or was a
director or an officer of the Association or is or was serving at the request of
the Association as a director, officer, employee or agent of another corporation
or of a partnership, joint venture, trust or other enterprise, including service
with respect to an employee benefit plan (hereinafter an "indemnitee"), whether
the basis of such proceeding is alleged action in an official capacity as a
director, officer, employee or agent or in any other capacity while serving as a
director, officer, employee or agent, shall be indemnified and held harmless by
the Association to the fullest extent authorized by the Delaware General
Corporation Law, as the same exists or may hereafter be amended (but, in the
case of any such amendment, only to the extent that such amendment permits the
Association to provide broader indemnification rights than such law permitted
the Association to provide prior to such amendment), against all expense,
liability and loss (including attorneys' fees, judgments, fines, ERISA excise
taxes or penalties and amounts paid in settlement) reasonably incurred or
suffered by such indemnitee in connection therewith; provided, however, that,
except as provided in Section 9.3 of these by-laws with respect to proceedings
to enforce rights to indemnification, the Association shall indemnify any such
indemnitee in connection with a proceeding (or part thereof) initiated by such
indemnitee only if such proceeding (or part thereof) was authorized by the
board.


Section 9.2.  Right to Advancement of Expenses.  The right to indemnification
conferred in Section 9.1 of these by-laws shall include the right to be paid by
the Association the expenses (including attorney's fees) incurred in defending
any such proceeding in advance of its final disposition (hereinafter an
"advancement of expenses"); provided, however, that, if the Delaware General
Corporation Law requires, an advancement of expenses incurred by an indemnitee
in his or her capacity as a director or officer (and not in any other capacity
in which service was or is rendered by such indemnitee, including, without
limitation, service to an employee benefit plan) shall be made only upon
delivery to the Association of an undertaking (hereinafter an "undertaking"), by
or on behalf of such indemnitee, to repay all amounts so advanced if it shall
ultimately be determined by final judicial decision from which there is no
further right to appeal (hereinafter a "final adjudication") that such
indemnitee is not entitled to be indemnified for such expenses under this
Section 9.2 or otherwise.  The rights to

                                      14
<PAGE>

indemnification and to the advancement of expenses conferred in Sections 9.1 and
9.2 of these by-laws shall be contract rights and such rights shall continue as
to an indemnitee who has ceased to be a director, officer, employee or agent and
shall inure to the benefit of the indemnities heirs, executors and
administrators.

Section 9.3.  Right of Indemnitee to Bring Suit.  If a claim under Section 9.1
or 9.2 of these by-laws is not paid in full by the Association within sixty (60)
days after a written claim has been received by the Association except in the
case of a claim for an advancement of expenses, in which case the applicable
period shall be twenty (20) days, the indemnitee may at any time thereafter
bring suit against the Association to recover the unpaid amount of the claim.
If successful in whole or in part in any such suit, or in a suit brought by the
Association to recover an advancement of expenses pursuant to the terms of an
undertaking, the indemnitee shall be entitled to be paid also the expense  of
prosecuting or defending such suit.  In (1) any suit brought by the indemnitee
to enforce a right to indemnification hereunder (but not in a suit brought by
the indemnitee to enforce a right to an advancement of expenses) it shall be a
defense that, and (2) any suit brought by the Association to recover an
advancement of expenses pursuant to the terms of an undertaking, the Association
shall be entitled to recover such expenses upon a final adjudication that, the
indemnitee has not met any applicable standard for indemnification set forth in
the Delaware General Corporation Law.  Neither the failure of the Association
(including the board, the Association's independent legal counsel, or its
shareholders) to have made a determination prior to the commencement of such
suit that indemnification of the indemnitee is proper in the circumstances
because the indemnitee has met the applicable standard of conduct set forth in
the Delaware General Corporation Law, nor an actual determination by the
Association (including the board, the Association's independent legal counsel,
or its shareholders) that the indemnitee has not met such applicable standard of
conduct, shall create a presumption that the indemnitee has not met the
applicable standard of conduct or, in the case of such a suit brought by the
indemnitee, be a defense to such suit.  In any suit brought by the indemnitee to
enforce a right to indemnification or to an advancement of expenses hereunder,
or brought by the Association to recover an advancement of expenses pursuant to
the terms of an undertaking, the burden of proving that the indemnitee is not
entitled to be indemnified, or to such advancement of expenses, under this
Article IX or otherwise shall be on the Association.

Section 9.4.  Non-Exclusivity of Rights.  The rights to indemnification and to
the advancement of expenses conferred in this Article IX shall not be exclusive
of any other right which any person may have or hereafter acquire under any
statute, the Association's Articles of Association, by-laws, agreement, vote of
shareholders or disinterested directors or otherwise.

Section 9.5.  Insurance.  The Association may maintain insurance, at its
expense, to protect itself and any director, officer, employee or agent of the
Association or another corporation, partnership, joint venture, trust or other
enterprise against any expense, liability or loss, whether or not the
Association would have the power to indemnify such person against such expense,
liability or loss under the Delaware General Corporation Law.

Section 9.6.  Indemnification of Employees and Agents of the Association.  The
Association may, to the extent authorized from time to time by the board, grant
rights to indemnification and to the advancement of expenses to any employee or
agent of the Association to the fullest extent of the provisions of this Article
IX with respect to the indemnification and advancement of expenses of directors
and officers of the Association.

                              Article X.  By-laws

Section 10.1. Inspection.  A copy of the by-laws, with all amendments, shall at
all times be kept in a convenient place at the main office of the Association,
and shall be open for inspection to all shareholders during banking hours.

Section 10.2. Amendments.  The by-laws may be amended, altered or repealed, at
any regular meeting of the board by a vote of a majority of the total number of
the directors except as provided below.  The Association's shareholders may
amend or repeal the by-laws even though the by-laws may be amended or repealed
by its board.

                            ARTICLES OF ASSOCIATION


For the purpose of organizing an Association to perform any lawful activities of
a national  bank, the undersigned do enter into the following Articles of
Association:

FIRST.  The title of this Association shall be Chase Manhattan Trust Company,
National Association (the "Association").

SECOND.  The main office of the Association shall be in the City of Pittsburgh,
County of Allegheny, Commonwealth of Pennsylvania.  The business of the
Association shall be limited to the fiduciary powers and the support of
activities incidental to the exercise of those powers.  The Association will
obtain the prior written approval of the Office of the Comptroller of the
Currency before amending these Articles of Association to expand the scope of
its activities and services.

THIRD.  The board of directors of this Association shall consist of not less
than five nor more than twenty-five persons, the exact number to be fixed and
determined from time to time by resolution of a majority of the full board of
directors or by resolution of a majority of the shareholders at any annual or
special meeting thereof.  Each director, during the full term of his
directorship, shall own common or preferred stock of the Association or of a
holding company owning the Association, with an aggregate par, fair market or
equity value of not less than $1,000.  Any vacancy in the board of directors may
be filled by action of the shareholders or a majority of the remaining
directors.

Terms of directors, including directors selected to fill vacancies, shall expire
at the next regular meeting of shareholders at which directors are elected,
unless the directors resign or are removed from office.

Despite the expiration of a director's term, the director shall continue to
serve until his or her successor is elected and qualifies or until there is a
decrease in the number of directors and his or her position is eliminated.



FOURTH.  There shall be an annual meeting of the shareholders to elect directors
and transact whatever other business may be brought before the meeting.  It
shall be held at the main office or any other convenient place the board of
directors may designate, on the day of each year specified therefore in the by-
laws, or if that day falls on a legal holiday in the state in which the
Association is located, on the next following banking day.  If no election is
held on the day fixed or in event of a legal holiday, on the following banking
day, an election may be held on any subsequent day within 60 days of the day
fixed, to be designated by the board of directors, or, if the directors fail to
fix the day, by shareholders representing two-thirds of the shares issued and
outstanding.  Advance notice of the meeting may be duly waived by the sole
shareholder in accordance with 12 C.F.R. 7.2001.

A director may resign at any time by delivering written notice to the board of
directors, its Chairperson, or to the Association, which resignation shall be
effective when the notice is delivered unless the notice specifies a later
effective date.

A director may be removed by shareholders at a meeting called to remove him or
her, when notice of the meeting stating that the purpose or one of the purposes
is to remove him or her is provided, if there is a failure to fulfill one of the
affirmative requirements for qualification, or for cause.

FIFTH.  The authorized amount of capital stock of this Association shall be five
million dollars ($5,000,000), divided into fifty thousand (50,000) shares of
common stock of the par value of one hundred dollars ($ 100) each; but said
capital stock may be increased or decreased from time to time, according to the
provisions of the laws of the United States.

No holder of shares of the capital stock of any class of the Association shall
have any preemptive or preferential right of subscription to any shares of any
class of stock of the Association, whether now or hereafter authorized, or to
any obligations convertible into stock of the

                                       4
<PAGE>

Association, issued, or sold, nor any right to subscription to any thereof other
than such, if any, as the board of directors, in its discretion may from time to
time determine and at such price as the board of directors may from time to time
fix.

Unless otherwise specified in the Articles of Association or required by law,
(1) all matters requiring shareholder action, including amendments to the
Articles of Association, must be approved by shareholders owning a majority
voting interest in the outstanding voting stock, and (2) each shareholder shall
be entitled to one vote per share.

The Association, at any time and from time to time, may authorize and issue debt
obligations, whether or not subordinated, without the approval of the
shareholders.

SIXTH.  The board of directors may appoint one of its members President of this
Association, and one of its members Chairperson of the board or two of its
members as Co-Chairpersons of the board, and shall have the power to appoint one
or more Vice Presidents, a Secretary who shall keep minutes of the directors'
and shareholders' meetings and be responsible for authenticating the records of
the Association, and such other officers and employees as may be required to
transact the business of this Association.  A duly appointed officer may appoint
one or more officers or assistant officers if authorized by the board of
directors in accordance with the by-laws.

The board of directors shall have the power to:
(1)  Define the duties of the officers, employees, and agents of the
Association.
(2)  Delegate the performance of its duties, but not the responsibility for its
duties, to the officers, employees, and agents of the Association.
(3)  Fix the compensation and enter into employment contracts with its officers
and employees upon reasonable terms and conditions consistent with applicable
law.
(4)  Dismiss officers and employees.
(5)  Require bonds from officers and employees and fix the penalty thereof.
(6)  Ratify written policies authorized by the Association's management or
committees of the board.
(7)  Regulate the manner in which any increase or decrease of the capital of the
Association shall be made, provided that nothing herein shall restrict the power
of shareholders to increase or decrease the capital of the Association in
accordance with law.
(8)  Manage and administer the business and affairs of the Association.
(9)  Adopt initial by-laws, not inconsistent with law or the Articles of

(11)  Make contracts.
(12) Generally perform all acts that are legal for a board of directors to
perform.

SEVENTH.  The board of directors shall have the power to change the location of
the main office to any other location permitted under applicable law, without

change the location of any branch or branches of the Association to any other
location permitted under applicable law, without the approval of the
shareholders subject to approval by the Office of the Comptroller of the
Currency.

EIGHTH.  The corporate existence of this Association shall continue until
termination according to the laws of the United States.

NINTH.  These Articles of Association may be amended at any regular or special
meeting of the shareholders by the affirmative vote of the holders of a majority
of the stock of this Association, unless the vote of the holders of a greater
amount of stock is required by law, and in that case by the vote of the holders
of such greater amount. The Association's board of directors may propose one or
more amendments to the Articles of Association for submission to the
shareholders.

Re:  Change in Corporate Title
       New Trust Company, National Association (Bank)
       Pittsburgh, Pennsylvania

Dear Mr. Bielawa:

The Office of the Comptroller of the Currency (OCC) has received your
submission, concerning the change and amendment to Article First of the above-
referenced Bank's Articles of Association. The OCC has amended its records to
reflect that effective November 24, 1997, the corporate title of New Trust
Company, National Association, Charter Number 23548, was changed to "Chase
Manhattan Trust Company, National Association."

You are reminded that the OCC does not approve national bank name changes nor
dies it maintain official titles or the retention of alternate titles. The use
of other titles or the retention of the rights o any previously title is the
responsibility of the Bank's board of directors. Legal counsel should be
consulted to determine whether or not the new title, or any previously used
title, could be challenged by competing institutions under the provisions of
federal state law.

A copy of the amended Article as accepted for filing is enclosed for the Bank's
records.

Very truly yours

Re:  Charter for a National Trust Bank, New Trust Company, National Association.
     Pittsburgh, Pennsylvania
     ACN 97 NE 01 0022

Dear Mr. Zupan:

The Comptroller of the Currency (OCC) has found that you have met all conditions
imposed by the OCC and completed all steps necessary to commence the business of
banking.  Your charter certificate is enclosed.  You are authorized to commence
business on November 24, 1997.

This letter also constitutes OCC authorization to  exercise fiduciary powers.

You are reminded that  several of the standard conditions contained in the
preliminary approval letter dated October 23, 1997 will continue to apply once
the bank opens and by opening, you agree to subject your association to these
conditions of operations.  Some of the conditions bear reiteration here:

1.   Regardless of the association's FDIC insurance status, the association is
     subject to the Change in Bank Control act (12 U.S.C. 1817(j)) by virtue of
     its national bank charter. Please refer to item 4 in the list of standard
     conditions sent with the preliminary approval letter.

2.   The board of directors is responsible for regular review and update of
     policies and procedures and for assuring ongoing compliance with them. This
     includes maintaining an internal control system that ensures compliance
     with the currency reporting and record keeping requirements of the Bank
     Secrecy Act (BSA). The board is expected to train its personnel in BSA
     procedures and designate one person or a group to monitor day-to-day
     compliance.

                                       8

3.   The bank will not engage in full commercial powers authorized to national
     banks without the OCC's prior approval

Following the commencement of operations, bank management is urged to become
familiar with the requirements of the Securities Exchange Act of 1934 and Part
11 of the Comptroller's regulations relative to the registration of the bank's
equity securities and related periodic reports.  These requirements will be
applicable to your bank when the number of shareholders of record is maintained
at 500 or more.  Such registration may be  subsequently terminated pursuant to
the Act, only when the number of shareholders of record is reduced to fewer than
300.

Should you have any questions regarding the supervision of your bank, please
contact the portfolio manager who will be responsible for OCC's ongoing
supervisory effort at your institution.  You will be notified of the name and
number of the appropriate individual in the near future.

Sincerely,

/s/ Micheal G. Tiscia

two the number of directors last elected by shareholders where such number was

the event of a vacancy in the board for any other cause, a director may be
appointed to fill such vacancy by vote of a majority of the remaining directors
then in office.

Association composed of four or more members, who shall be capable and
experienced officers or directors of the Association.  The Committee is charged
with the responsibility for the investment, retention, or disposition of assets
held in accounts with respect to which the Association has investment authority;
for the review of the assets of accounts for which the Association has
investment authority promptly after the acceptance of such an account and at
least once during every calendar year thereafter to determine the advisability
of retaining or disposing of such assets; for the determination of the manner in
which proxies received for accounts for which the Association has responsibility

and/or income in respect of any account; for providing advice as to the
investment, retention, or disposition of assets in investment advisory accounts
maintained by the Association; for the making of such reports as this board

Article VI. Stock and Stock Certificates

Section 6.1.  Transfers.  Shares of stock shall be transferable on the books of
the Association, and a transfer book shall be kept in which all transfers of
stock shall be recorded.  Every person becoming a shareholder by such transfer
shall, in proportion to his or her shares, succeed to all rights of the prior
holder of such shares. The board may impose conditions upon the transfer of the
stock reasonably calculated to simplify the work of the Association with respect
to stock transfers, voting at shareholder meetings, and related matters and to
protect it against fraudulent transfers.

Section 6.2.  Stock Certificates.  Certificates of stock shall bear the
signature of the Chairperson or Co-Chairpersons of the board or President (which
may be engraved, printed or impressed), and shall be signed manually or by
facsimile process by the Secretary, Assistant Secretary, Cashier, Assistant
Cashier, or any other officer appointed by the board for that purpose, to be
known as an authorized officer, and the seal of the Association shall be
engraved thereon.  Each certificate shall recite on its face that the stock
represented thereby is transferable only upon the books of the Association
properly endorsed.  In case any such officer who has signed or whose facsimile
signature has been placed upon such certificate shall have ceased to be such
before such certificate is issued, it may be issued by the Association with the
same effect as if such officer had not ceased to be such at the time of its
issue.  The corporate seal may be a facsimile, engraved or printed.

verified, delivered or accepted on behalf of the Association in such other
manner and by such other officers as the board may from time to time direct.

Cashier or other officer appointed to act as Secretary of the meeting.

with applicable Federal banking law, bank safety and soundness or these by-laws,
the corporate governance procedures found in the Delaware General Corporation
Law shall be followed by the Association.


                         Article IX.  Indemnification

Section 9.1.  Right to Indemnification.  Each person who was or is made a party
or is threatened to be made a party to or is otherwise involved in any action,
suit or proceeding, whether civil, criminal, administrative or investigative
(hereinafter a "proceeding"), by reason of the fact that he or she is or was a
director or an officer of the Association or is or was serving at the request of
the Association as a director, officer, employee or agent of another corporation
or of a partnership, joint venture, trust or other enterprise, including service
with respect to an employee benefit plan (hereinafter an "indemnitee"), whether
the basis of such proceeding is alleged action in an official capacity as a
director, officer, employee or agent or in any other capacity while serving as a
director, officer, employee or agent, shall be indemnified and held harmless by
the Association to the fullest extent authorized by the Delaware General
Corporation Law, as the same exists or may hereafter be amended (but, in the
case of any such amendment, only to the extent that such amendment permits the
Association to provide broader indemnification rights than such law permitted
the Association to provide prior to such amendment), against all expense,
liability and loss (including attorneys' fees, judgments, fines, ERISA excise
taxes or penalties and amounts paid in settlement) reasonably incurred or
suffered by such indemnitee in connection therewith; provided, however, that,
except as provided in Section 9.3 of these by-laws with respect to proceedings
to enforce rights to indemnification, the Association shall indemnify any such
indemnitee in connection with a proceeding (or part thereof) initiated by such
indemnitee only if such proceeding (or part thereof) was authorized by the
board.


Section 9.2.  Right to Advancement of Expenses.  The right to indemnification
conferred in Section 9.1 of these by-laws shall include the right to be paid by
the Association the expenses (including attorney's fees) incurred in defending
any such proceeding in advance of its final disposition (hereinafter an
"advancement of expenses"); provided, however, that, if the Delaware General
Corporation Law requires, an advancement of expenses incurred by an indemnitee
in his or her capacity as a director or officer (and not in any other capacity
in which service was or is rendered by such indemnitee, including, without
limitation, service to an employee benefit plan) shall be made only upon
delivery to the Association of an undertaking (hereinafter an "undertaking"), by
or on behalf of such indemnitee, to repay all amounts so advanced if it shall
ultimately be determined by final judicial decision from which there is no
further right to appeal (hereinafter a "final adjudication") that such
indemnitee is not entitled to be indemnified for such expenses under this
Section 9.2 or otherwise.  The rights to

                                      14
<PAGE>

indemnification and to the advancement of expenses conferred in Sections 9.1 and
9.2 of these by-laws shall be contract rights and such rights shall continue as
to an indemnitee who has ceased to be a director, officer, employee or agent and
shall inure to the benefit of the indemnities heirs, executors and
administrators.

Section 9.3.  Right of Indemnitee to Bring Suit.  If a claim under Section 9.1
or 9.2 of these by-laws is not paid in full by the Association within sixty (60)
days after a written claim has been received by the Association except in the
case of a claim for an advancement of expenses, in which case the applicable
period shall be twenty (20) days, the indemnitee may at any time thereafter
bring suit against the Association to recover the unpaid amount of the claim.
If successful in whole or in part in any such suit, or in a suit brought by the
Association to recover an advancement of expenses pursuant to the terms of an
undertaking, the indemnitee shall be entitled to be paid also the expense  of
prosecuting or defending such suit.  In (1) any suit brought by the indemnitee
to enforce a right to indemnification hereunder (but not in a suit brought by
the indemnitee to enforce a right to an advancement of expenses) it shall be a
defense that, and (2) any suit brought by the Association to recover an
advancement of expenses pursuant to the terms of an undertaking, the Association
shall be entitled to recover such expenses upon a final adjudication that, the
indemnitee has not met any applicable standard for indemnification set forth in
the Delaware General Corporation Law.  Neither the failure of the Association
(including the board, the Association's independent legal counsel, or its
shareholders) to have made a determination prior to the commencement of such
suit that indemnification of the indemnitee is proper in the circumstances
because the indemnitee has met the applicable standard of conduct set forth in
the Delaware General Corporation Law, nor an actual determination by the
Association (including the board, the Association's independent legal counsel,
or its shareholders) that the indemnitee has not met such applicable standard of
conduct, shall create a presumption that the indemnitee has not met the
applicable standard of conduct or, in the case of such a suit brought by the
indemnitee, be a defense to such suit.  In any suit brought by the indemnitee to
enforce a right to indemnification or to an advancement of expenses hereunder,
or brought by the Association to recover an advancement of expenses pursuant to
the terms of an undertaking, the burden of proving that the indemnitee is not
entitled to be indemnified, or to such advancement of expenses, under this
Article IX or otherwise shall be on the Association.

Section 9.4.  Non-Exclusivity of Rights.  The rights to indemnification and to
the advancement of expenses conferred in this Article IX shall not be exclusive
of any other right which any person may have or hereafter acquire under any
statute, the Association's Articles of Association, by-laws, agreement, vote of
shareholders or disinterested directors or otherwise.

Section 9.5.  Insurance.  The Association may maintain insurance, at its
expense, to protect itself and any director, officer, employee or agent of the
Association or another corporation, partnership, joint venture, trust or other
enterprise against any expense, liability or loss, whether or not the
Association would have the power to indemnify such person against such expense,
liability or loss under the Delaware General Corporation Law.

Section 9.6.  Indemnification of Employees and Agents of the Association.  The
Association may, to the extent authorized from time to time by the board, grant
rights to indemnification and to the advancement of expenses to any employee or
agent of the Association to the fullest extent of the provisions of this Article
IX with respect to the indemnification and advancement of expenses of directors
and officers of the Association.

                              Article X.  By-laws

Section 10.1. Inspection.  A copy of the by-laws, with all amendments, shall at
all times be kept in a convenient place at the main office of the Association,
and shall be open for inspection to all shareholders during banking hours.

Section 10.2. Amendments.  The by-laws may be amended, altered or repealed, at
any regular meeting of the board by a vote of a majority of the total number of
the directors except as provided below.  The Association's shareholders may
amend or repeal the by-laws even though the by-laws may be amended or repealed
by its board.

                               CHARTER NO. 23548

                            ARTICLES OF ASSOCIATION


For the purpose of organizing an Association to perform any lawful activities of
a national  bank, the undersigned do enter into the following Articles of
Association:

FIRST.  The title of this Association shall be Chase Manhattan Trust Company,
National Association (the "Association").

SECOND.  The main office of the Association shall be in the City of Pittsburgh,
County of Allegheny, Commonwealth of Pennsylvania.  The business of the
Association shall be limited to the fiduciary powers and the support of
activities incidental to the exercise of those powers.  The Association will
obtain the prior written approval of the Office of the Comptroller of the
Currency before amending these Articles of Association to expand the scope of
its activities and services.

THIRD.  The board of directors of this Association shall consist of not less
than five nor more than twenty-five persons, the exact number to be fixed and
determined from time to time by resolution of a majority of the full board of
directors or by resolution of a majority of the shareholders at any annual or
special meeting thereof.  Each director, during the full term of his
directorship, shall own common or preferred stock of the Association or of a
holding company owning the Association, with an aggregate par, fair market or
equity value of not less than $1,000.  Any vacancy in the board of directors may
be filled by action of the shareholders or a majority of the remaining
directors.

Terms of directors, including directors selected to fill vacancies, shall expire
at the next regular meeting of shareholders at which directors are elected,
unless the directors resign or are removed from office.

Despite the expiration of a director's term, the director shall continue to
serve until his or her successor is elected and qualifies or until there is a
decrease in the number of directors and his or her position is eliminated.



FOURTH.  There shall be an annual meeting of the shareholders to elect directors
and transact whatever other business may be brought before the meeting.  It
shall be held at the main office or any other convenient place the board of
directors may designate, on the day of each year specified therefore in the by-
laws, or if that day falls on a legal holiday in the state in which the
Association is located, on the next following banking day.  If no election is
held on the day fixed or in event of a legal holiday, on the following banking
day, an election may be held on any subsequent day within 60 days of the day
fixed, to be designated by the board of directors, or, if the directors fail to
fix the day, by shareholders representing two-thirds of the shares issued and
outstanding.  Advance notice of the meeting may be duly waived by the sole
shareholder in accordance with 12 C.F.R. 7.2001.

A director may resign at any time by delivering written notice to the board of
directors, its Chairperson, or to the Association, which resignation shall be
effective when the notice is delivered unless the notice specifies a later
effective date.

A director may be removed by shareholders at a meeting called to remove him or
her, when notice of the meeting stating that the purpose or one of the purposes
is to remove him or her is provided, if there is a failure to fulfill one of the
affirmative requirements for qualification, or for cause.

FIFTH.  The authorized amount of capital stock of this Association shall be five
million dollars ($5,000,000), divided into fifty thousand (50,000) shares of
common stock of the par value of one hundred dollars ($ 100) each; but said
capital stock may be increased or decreased from time to time, according to the
provisions of the laws of the United States.

No holder of shares of the capital stock of any class of the Association shall
have any preemptive or preferential right of subscription to any shares of any
class of stock of the Association, whether now or hereafter authorized, or to
any obligations convertible into stock of the

                                       4
<PAGE>

Association, issued, or sold, nor any right to subscription to any thereof other
than such, if any, as the board of directors, in its discretion may from time to
time determine and at such price as the board of directors may from time to time
fix.

Unless otherwise specified in the Articles of Association or required by law,
(1) all matters requiring shareholder action, including amendments to the
Articles of Association, must be approved by shareholders owning a majority
voting interest in the outstanding voting stock, and (2) each shareholder shall
be entitled to one vote per share.

The Association, at any time and from time to time, may authorize and issue debt
obligations, whether or not subordinated, without the approval of the
shareholders.

SIXTH.  The board of directors may appoint one of its members President of this
Association, and one of its members Chairperson of the board or two of its
members as Co-Chairpersons of the board, and shall have the power to appoint one
or more Vice Presidents, a Secretary who shall keep minutes of the directors'
and shareholders' meetings and be responsible for authenticating the records of
the Association, and such other officers and employees as may be required to
transact the business of this Association.  A duly appointed officer may appoint
one or more officers or assistant officers if authorized by the board of
directors in accordance with the by-laws.

The board of directors shall have the power to:
(1)  Define the duties of the officers, employees, and agents of the
Association.
(2)  Delegate the performance of its duties, but not the responsibility for its
duties, to the officers, employees, and agents of the Association.
(3)  Fix the compensation and enter into employment contracts with its officers
and employees upon reasonable terms and conditions consistent with applicable
law.
(4)  Dismiss officers and employees.
(5)  Require bonds from officers and employees and fix the penalty thereof.
(6)  Ratify written policies authorized by the Association's management or
committees of the board.
(7)  Regulate the manner in which any increase or decrease of the capital of the
Association shall be made, provided that nothing herein shall restrict the power
of shareholders to increase or decrease the capital of the Association in
accordance with law.
(8)  Manage and administer the business and affairs of the Association.
(9)  Adopt initial by-laws, not inconsistent with law or the Articles of
Association, for managing the business and regulating the affairs of the
Association.
(10) Amend or repeal by-laws, except to the extent that the Articles of
Association reserve this power in whole or in part to shareholders.
(11)  Make contracts.
(12) Generally perform all acts that are legal for a board of directors to
perform.

SEVENTH.  The board of directors shall have the power to change the location of
the main office to any other location permitted under applicable law, without
the approval of the shareholders, and shall have the power to establish or
change the location of any branch or branches of the Association to any other
location permitted under applicable law, without the approval of the
shareholders subject to approval by the Office of the Comptroller of the
Currency.

EIGHTH.  The corporate existence of this Association shall continue until
termination according to the laws of the United States.

NINTH.  These Articles of Association may be amended at any regular or special
meeting of the shareholders by the affirmative vote of the holders of a majority
of the stock of this Association, unless the vote of the holders of a greater
amount of stock is required by law, and in that case by the vote of the holders
of such greater amount.  The Association's board of directors may propose one or
more amendments to the Articles of Association for submission to the
shareholders.

Re:  Change in Corporate Title

       Pittsburgh, Pennsylvania

Dear Mr. Bielawa:

The Office of the Comptroller of the Currency (OCC) has received your
submission, concerning the change and amendment to Article First of the above-
referenced Bank's Articles of Association. The OCC has amended its records to
reflect that effective November 24, 1997, the corporate title of New Trust
Company, National Association, Charter Number 23548, was changed to "Chase
Manhattan Trust Company, National Association."

You are reminded that the OCC does not approve national bank name changes nor
dies it maintain official titles or the retention of alternate titles. The use
of other titles or the retention of the rights o any previously title is the
responsibility of the Bank's board of directors. Legal counsel should be
consulted to determine whether or not the new title, or any previously used
title, could be challenged by competing institutions under the provisions of
federal state law.

A copy of the amended Article as accepted for filing is enclosed for the Bank's
records.

Very truly yours

Re:  Charter for a National Trust Bank, New Trust Company, National Association.
     Pittsburgh, Pennsylvania
     ACN 97 NE 01 0022

Dear Mr. Zupan:

The Comptroller of the Currency (OCC) has found that you have met all conditions
imposed by the OCC and completed all steps necessary to commence the business of
banking.  Your charter certificate is enclosed.  You are authorized to commence
business on November 24, 1997.

This letter also constitutes OCC authorization to exercise fiduciary powers.

You are reminded that several of the standard conditions contained in the
preliminary approval letter dated October 23, 1997 will continue to apply once
the bank opens and by opening, you agree to subject your association to these
conditions of operations.  Some of the conditions bear reiteration here:

1.   Regardless of the association's FDIC insurance status, the association is
     subject to the Change in Bank Control act (12 U.S.C. 1817(j)) by virtue of
     its national bank charter. Please refer to item 4 in the list of standard
     conditions sent with the preliminary approval letter.

2.   The board of directors is responsible for regular review and update of
     policies and procedures and for assuring ongoing compliance with them. This
     includes maintaining an internal control system that ensures compliance
     with the currency reporting and record keeping requirements of the Bank
     Secrecy Act (BSA). The board is expected to train its personnel in BSA
     procedures and designate one person or a group to monitor day-to-day
     compliance.

3.   The bank will not engage in full commercial powers authorized to national
     banks without the OCC's prior approval

Following the commencement of operations, bank management is urged to become
familiar with the requirements of the Securities Exchange Act of 1934 and Part
11 of the Comptroller's regulations relative to the registration of the bank's
equity securities and related periodic reports.  These requirements will be
applicable to your bank when the number of shareholders of record is maintained
at 500 or more.  Such registration may be  subsequently terminated pursuant to
the Act, only when the number of shareholders of record is reduced to fewer than
300.

Should you have any questions regarding the supervision of your bank, please
contact the portfolio manager who will be responsible for OCC's ongoing
supervisory effort at your institution.  You will be notified of the name and
number of the appropriate individual in the near future.

Sincerely,

/s/ Micheal G. Tiscia

three or more directors.  Each member of the board shall be given notice stating
the time and place, by telegram, telephone, letter or in person, of each such
special meeting at least one day prior to such meeting.  Any business may be
transacted at any special meeting.

Section 2.6.  Action by the Board.  Except as otherwise provided by law,
corporate action to be taken by the board shall mean such action at a meeting of
the board.  Any action required or permitted to be taken by the board or any
committee of the board may be taken without a meeting if all members of the
board or the committee consent in writing to a resolution authorizing the
action.  The resolution and the written consents thereto shall be filed with the
minutes of the proceedings of the board or committee.  Any one or more members
of the board or any committee may participate in a meeting of the board or
committee by means of a conference telephone or similar communications equipment
allowing all persons participating in the meeting to hear each other at the same
time.  Participation by such means shall constitute presence in person at such
meeting.

Section 2.7.  Waiver of Notice.  Notice of a special meeting need not be given

the meeting, or who attends the meeting without protesting, prior thereto or at
its commencement, the lack of notice to him or her.

Section 2.8.  Quorum and Manner of Acting.  Except as otherwise required by law,
the Articles of Association or these by-laws, a majority of the directors shall
constitute a quorum for the transaction of any business at any meeting of the
board and the act of a majority of the directors present and voting at a meeting
at which a quorum is present shall be the act of the board.  In the absence of a
quorum, a majority of the directors present may adjourn any meeting, from time
to time, until a quorum is present and no notice of any adjourned meeting need
be given.  At any such adjourned meeting at which a quorum is present, any
business may be transacted which might have been transacted at the meeting as
originally called.

Section 2.9.  Vacancies.  In the event a majority of the full board increases
the number of directors to a number which exceeds the number of directors last
elected by shareholders, as permitted by Section 2.2, directors may be appointed
to fill the resulting vacancies by vote of such majority of the full board.  In
the event of a vacancy in the board for any other cause, a director may be
appointed to fill such vacancy by vote of a majority of the remaining directors
then in office.

Section 2.10.  Removal of Directors.  The vacancy created by the removal of a
director pursuant to this Section may be filled by the board in accordance with
Section 2.9 of these by-laws or by the shareholders.

Association composed of four or more members, who shall be capable and
experienced officers or directors of the Association.  The Committee is charged

Article VI. Stock and Stock Certificates

Section 6.1.  Transfers.  Shares of stock shall be transferable on the books of
the Association, and a transfer book shall be kept in which all transfers of
stock shall be recorded.  Every person becoming a shareholder by such transfer
shall, in proportion to his or her shares, succeed to all rights of the prior
holder of such shares. The board may impose conditions upon the transfer of the
stock reasonably calculated to simplify the work of the Association with respect
to stock transfers, voting at shareholder meetings, and related matters and to
protect it against fraudulent transfers.

signature of the Chairperson or Co-Chairpersons of the board or President (which

engraved thereon.  Each certificate shall recite on its face that the stock
represented thereby is transferable only upon the books of the Association
properly endorsed.  In case any such officer who has signed or whose facsimile
signature has been placed upon such certificate shall have ceased to be such
before such certificate is issued, it may be issued by the Association with the
same effect as if such officer had not ceased to be such at the time of its
issue.  The corporate seal may be a facsimile, engraved or printed.

                         Article IX.  Indemnification

Section 9.1.  Right to Indemnification.  Each person who was or is made a party
or is threatened to be made a party to or is otherwise involved in any action,
suit or proceeding, whether civil, criminal, administrative or investigative
(hereinafter a "proceeding"), by reason of the fact that he or she is or was a
director or an officer of the Association or is or was serving at the request of
the Association as a director, officer, employee or agent of another corporation
or of a partnership, joint venture, trust or other enterprise, including service
with respect to an employee benefit plan (hereinafter an "indemnitee"), whether
the basis of such proceeding is alleged action in an official capacity as a
director, officer, employee or agent or in any other capacity while serving as a
director, officer, employee or agent, shall be indemnified and held harmless by
the Association to the fullest extent authorized by the Delaware General
Corporation Law, as the same exists or may hereafter be amended (but, in the
case of any such amendment, only to the extent that such amendment permits the
Association to provide broader indemnification rights than such law permitted
the Association to provide prior to such amendment), against all expense,
liability and loss (including attorneys' fees, judgments, fines, ERISA excise
taxes or penalties and amounts paid in settlement) reasonably incurred or
suffered by such indemnitee in connection therewith; provided, however, that,
except as provided in Section 9.3 of these by-laws with respect to proceedings
to enforce rights to indemnification, the Association shall indemnify any such
indemnitee in connection with a proceeding (or part thereof) initiated by such
indemnitee only if such proceeding (or part thereof) was authorized by the
board.



Section 9.2.  Right to Advancement of Expenses.  The right to indemnification
conferred in Section 9.1 of these by-laws shall include the right to be paid by
the Association the expenses (including attorney's fees) incurred in defending
any such proceeding in advance of its final disposition (hereinafter an
"advancement of expenses"); provided, however, that, if the Delaware General
Corporation Law requires, an advancement of expenses incurred by an indemnitee
in his or her capacity as a director or officer (and not in any other capacity
in which service was or is rendered by such indemnitee, including, without
limitation, service to an employee benefit plan) shall be made only upon
delivery to the Association of an undertaking (hereinafter an "undertaking"), by
or on behalf of such indemnitee, to repay all amounts so advanced if it shall
ultimately be determined by final judicial decision from which there is no
further right to appeal (hereinafter a "final adjudication") that such
indemnitee is not entitled to be indemnified for such expenses under this
Section 9.2 or otherwise.  The rights to

                                       14
<PAGE>

indemnification and to the advancement of expenses conferred in Sections 9.1 and
9.2 of these by-laws shall be contract rights and such rights shall continue as
to an indemnitee who has ceased to be a director, officer, employee or agent and
shall inure to the benefit of the indemnities heirs, executors and
administrators.

Section 9.3.  Right of Indemnitee to Bring Suit.  If a claim under Section 9.1
or 9.2 of these by-laws is not paid in full by the Association within sixty (60)
days after a written claim has been received by the Association except in the
case of a claim for an advancement of expenses, in which case the applicable
period shall be twenty (20) days, the indemnitee may at any time thereafter
bring suit against the Association to recover the unpaid amount of the claim.
If successful in whole or in part in any such suit, or in a suit brought by the
Association to recover an advancement of expenses pursuant to the terms of an
undertaking, the indemnitee shall be entitled to be paid also the expense  of
prosecuting or defending such suit.  In (1) any suit brought by the indemnitee
to enforce a right to indemnification hereunder (but not in a suit brought by
the indemnitee to enforce a right to an advancement of expenses) it shall be a
defense that, and (2) any suit brought by the Association to recover an
advancement of expenses pursuant to the terms of an undertaking, the Association
shall be entitled to recover such expenses upon a final adjudication that, the
indemnitee has not met any applicable standard for indemnification set forth in
the Delaware General Corporation Law.  Neither the failure of the Association
(including the board, the Association's independent legal counsel, or its
shareholders) to have made a determination prior to the commencement of such
suit that indemnification of the indemnitee is proper in the circumstances
because the indemnitee has met the applicable standard of conduct set forth in
the Delaware General Corporation Law, nor an actual determination by the
Association (including the board, the Association's independent legal counsel,
or its shareholders) that the indemnitee has not met such applicable standard of
conduct, shall create a presumption that the indemnitee has not met the
applicable standard of conduct or, in the case of such a suit brought by the
indemnitee, be a defense to such suit.  In any suit brought by the indemnitee to
enforce a right to indemnification or to an advancement of expenses hereunder,
or brought by the Association to recover an advancement of expenses pursuant to
the terms of an undertaking, the burden of proving that the indemnitee is not
entitled to be indemnified, or to such advancement of expenses, under this
Article IX or otherwise shall be on the Association.

Section 9.4.  Non-Exclusivity of Rights.  The rights to indemnification and to
the advancement of expenses conferred in this Article IX shall not be exclusive
of any other right which any person may have or hereafter acquire under any
statute, the Association's Articles of Association, by-laws, agreement, vote of
shareholders or disinterested directors or otherwise.

Section 9.5.  Insurance.  The Association may maintain insurance, at its
expense, to protect itself and any director, officer, employee or agent of the
Association or another corporation, partnership, joint venture, trust or other
enterprise against any expense, liability or loss, whether or not the
Association would have the power to indemnify such person against such expense,
liability or loss under the Delaware General Corporation Law.

Section 9.6.  Indemnification of Employees and Agents of the Association.  The
Association may, to the extent authorized from time to time by the board, grant
rights to indemnification and to the advancement of expenses to any employee or
agent of the Association to the fullest extent of the provisions of this Article
IX with respect to the indemnification and advancement of expenses of directors
and officers of the Association.

                              Article X.  By-laws

Section 10.1.  Inspection.  A copy of the by-laws, with all amendments, shall at
all times be kept in a convenient place at the main office of the Association,
and shall be open for inspection to all shareholders during banking hours.

Section 10.2.  Amendments.  The by-laws may be amended, altered or repealed, at
any regular meeting of the board by a vote of a majority of the total number of
the directors except as provided below.  The Association's shareholders may
amend or repeal the by-laws even though the by-laws may be amended or repealed
by its board.
