PART II   FOR PAYEES EXEMPT FROM BACKUP WITHHOLDING (See the instructions on 
page 2.)
--------------------------------------------------------------------------------
>
--------------------------------------------------------------------------------
PART III  CERTIFICATION
--------------------------------------------------------------------------------
Under penalties of perjury, I certify that:

1.   The number shown on this form is my correct taxpayer identification number 
     (or I am waiting for a number to be issued to me), and

2.   I am not subject to backup withholding because: (a) I am exempt from backup
     withholding, or (b) I have not been notified by the Internal Revenue
     Service (IRS) that I am subject to backup withholding as a result of a
     failure to report all interest or dividends, or (c) the IRS has notified me
     that I am no longer subject to backup withholding.

CERTIFICATION INSTRUCTIONS.--You must cross out item 2 above if you have been 
notified by the IRS that you are currently subject to backup withholding because
you have failed to report all interest and dividends on your tax return.  For 
real estate transactions, item 2 does not apply.  For mortgage interest paid, 
acquisition or abandonment of secured property, cancellation of debt, 
contributions to an individual retirement arrangement (IRA), and generally, 
payments other than interest and dividends, you are not required to sign the 
Certification, but you must provide your correct TIN.  (See the instructions on 
page 2.)
--------------------------------------------------------------------------------
Sign  |
Here  | Signature >                                   Date >
--------------------------------------------------------------------------------
PURPOSE OF FORM.--A person who is required to file an information return with
the IRS must get your correct taxpayer identification number (TIN) to report,
for example, income paid to you, real estate transactions, mortgage interest you
paid, acquisition or abandonment of secured property, cancellation of debt, or
contributions you made to an IRA.

     Use Form W-9 to give your correct TIN to the person requesting it (the 
requester) and, when applicable, to:

     1.   Certify the TIN you are giving is correct (or you are waiting for a 
number to be issued),

     2.   Certify you are not subject to backup withholding, or

     3.   Claim exemption from backup withholding if you are an exempt payee.

NOTE:  If a requester give you a form other than a W-9 to request your TIN, you 
must use the requester's form if it is substantially similar to this Form W-9.

WHAT IS BACKUP WITHHOLDING?--Persons making certain payments to you must 
withhold and pay to the IRS 31% of such payments under certain conditions.  This
is called "backup withholding."  Payments that may be subject to backup 
withholding include interest, dividends, broker and barter 
exchange-transactions, rents, royalties, nonemployee pay, and certain payments 
from fishing boat operators.  Real estate transactions are not subject to backup
withholding.

     If you give the requester your correct TIN, make the proper certifications,
and report all your taxable interest and dividends on your tax return, payments
you receive will not be subject to backup withholding. Payments you receive will
be subject to backup withholding if:

     1.   You do not furnish your TIN to the requester, or

     2.   The IRS tells the requester that you furnished an incorrect TIN, or

     3.   The IRS tells you that you are subject to backup withholding because 
you did not report all your interest and dividends on your tax return (for 
reportable interest and dividends only), or

     4.   You do not certify to the requester that you are not subject to backup
withholding under 3 above (for reportable interest and dividend accounts opened 
after 1983 only), or

     5.   You do not certify your TIN when required.  See the Part III 
instructions on page 2 for details.

     Certain payees and payments are exempt from backup withholding.  See the 
Part II instructions and the separate INSTRUCTIONS FOR THE REQUESTER OF FORM 
W-9.

PENALTIES

FAILURE TO FURNISH TIN.--If you fail to furnish your correct TIN to a requester,
you are subject to a penalty of $50 for each such failure unless your failure is
due to reasonable cause and not to willful neglect.

CIVIL PENALTY FOR FALSE INFORMATION WITH RESPECT TO WITHHOLDING.--If you make a 
false statement with no reasonable basis that results in no backup withholding, 
you are subject to a $500 penalty.

CRIMINAL PENALTY FOR FALSIFYING INFORMATION.--Willfully falsifying 
certifications or affirmations may subject you to criminal penalties including 
fines and/or imprisonment.

MISUSE OF TINS.--If the requester discloses or uses TINs in violation of Federal
law, the requester may be subject to civil and criminal penalties.

                       This is A Contractual Agreement.
                 Do Not Sign Until You Have Read It Carefully.
              Retain one copy of this contract for your records.

     In consideration of your accepting and/or continuing one or more accounts 
either individually or jointly with others (hereinafter referred to as the 
"accounts") for me in the purchase and/or sale of securities and/or other 
property usually and customarily dealt in on exchanges, boards and markets 
(hereinafter referred to as "property"). I agree as follows:

     1.   STOCK EXCHANGE RULES AND SECURITIES LAWS.  All transactions under this
Agreement shall be subject to the constitution, rules, regulations, customs and 
practices of the exchange or market, and clearing corporation, if any, where 
such transactions are executed; and to the rules and regulations of the 
Securities and Exchange Commission, the Board of Governors of the Federal 
Reserve System, and all other applicable federal and state agencies and 
self-regulatory organizations. If any future acts, orders, rules or regulations 
amendatory of the foregoing and/or supplemental thereto are inconsistent with 
any of the provisions hereof, such provisions shall be deemed modified or 
superceded and all other provisions shall continue in full force and effect.

     2.   ORDERS TO PURCHASE OR SELL.  All orders for the purchase or sale of 
any property are given by me and executed for me with the distinct understanding
on my part that an actual purchase or sale is intended and that it is my 
intention and obligation to deliver property to cover any and all of my sales 
and in the case of purchases to receive and pay for such property and that I 
will do so upon your demand. I agree not to exceed the position limits set by 
you or by any federal agency as well as limits established by options exchanges 
for my own account, acting alone or in concert with others. I agree I will not 
place an order to purchase a security which, at the time of the order and 
purchase, I intend to sell before I have fully paid therefor.

     3.   CLOSING OF ACCOUNT; PAYMENT OF OBLIGATIONS.  At any time upon your 
demand, I shall discharge my liabilities to you, or, in the event of a closing 
of any of the accounts by you or me, in whole or in part. I shall pay you the 
deficiency, if any, and no oral agreement or instructions to the contrary shall 
be recognized or enforceable. I will maintain such collateral and/or margin as 
you, in your sole discretion, require from time to time and will pay promptly on
demand any amount owing with respect to the accounts.

     4.   GRANT OF LIEN; YOUR RIGHT TO SATISFY MY OBLIGATIONS FROM LIENED 
PROPERTY.  Subject to the provisions of applicable statutes and regulations, I 
hereby grant to you a general and continuing lien and security interest in any 
or all of the property which may at any time be held, purchased and/or carried 
by you in the accounts and any or all of my property which may at any time be in
your possession or control for any reason, including safekeeping, for the 
payment of all obligations and liabilities of mine to you however and whenever 
arising, irrespective of whether you have made advances in connection with such 
property and irrespective of the number of accounts I may have with you; and you
are hereby authorized without notice to me, whenever you deem it advisable, to 
apply and/or transfer interchangeably between any accounts I may have with you 
(either individually or jointly) any or all of the property so held, and without
notice to me and without regard as to whether you have (1) made advances with 
respect to such property or (2) in your possession or subject to your control at
the time thereof other property of the same kind and amount, to transfer, sell
and/or purchase any and all property in any of my accounts withhold, in the
usual course of business to satisfy such obligations and liabilities to you and
such general lien and security interest.

     5.   YOUR RIGHTS IF I DEFAULT.  Whenever in the exercise of your 
discretion you deem it necessary for your protection, you are hereby authorized 
and empowered to cancel outstanding orders for the purchase or sale of any 
property and, with or without prior demand or notice to me for initial or 
maintenance margin, or delivery of securities, to sell, assign and deliver all 
or any part of the property held or carried in the accounts and you may borrow 
or buy in any property required to make delivery against any sales including a 
short sale in account. Any loss resulting therefrom shall be charged to the 
accounts and I agree to indemnify and hold you harmless from all liability for 
such loss. Such purchase or sale may be public or private and may be made in 
such manner as you may in your absolute discretion determine, and no demands, 
calls, tenders or notices which you may make or give in any one or more 
instances will invalidate the aforesaid waiver on my part. Notwithstanding the 
foregoing, I understand that any such disposition of property must be in a 
commercially reasonable manner. Upon any such purchase or sale, and after 
deducting all costs and expenses (including reasonable attorney's fees) of a 
purchase or of sale and deliver, the residue of the proceeds will be applied to 
the payment of any liabilities to you and the surplus, if any, will be returned 
or credited to me. You may purchase the property free of any right of redemption
at any such sale and I shall be and remain liable for any deficiency in the 
accounts. In the event of my death, incompetency or disability you and your 
pledgees shall have like power to sell, buy or cancel as herein provided without
prior notice and without prior demand and before the appointment or 
qualification of executors, administrators, personal representatives, committees
or conservators of my estate and/or property as if I were alive and competent.

     6.   AGENCY.  In all transactions for my account, I understand you are 
acting only in an agency capacity and not for the contra party, except when you 
disclose to me in writing at or before the completion of a particular 
transaction that you are acting with respect to such transaction as dealers for 
your own account or as broker for some other person.

     7.   DEPOSIT OF MONIES; COMMINGLING.  You may deposit all monies received 
from me, or in which I have an interest, in your general bank account and 
commingle them with your monies and the monies of any other person.

     8.   EVENT BEYOND YOUR CONTROL.  You shall have no liability for losses or 
actions caused directly or indirectly by execution, attachment, injunction, or 
other legal process, or government restrictions, exchange, clearing house or 
self-regulatory agency rulings or any other cause beyond your control.

     9.   CONFIRMATIONS.  Written confirmation of the purchase or sale of 
property and statements of the accounts shall be conclusive if forwarded to me 
within a reasonable time and if not objected to by me in writing within ten (10)
calendar days after receipt.

     10.  LONG SALES.  When placing any order for long account, I will designate
it as such and hereby authorize you to mark such order as being "long". Any sell
order which I designate as being for long account will be for securities then 
owned or subject to immediate receipt by me and, if such securities are not then
deliverable by you from the accounts, I agree to deliver them in sufficient time
to fulfill any sell commitment and all applicable rules and regulations.

     11.  COMMUNICATIONS AND NOTICES.  Communications may be sent to me at the 
address on your records, or at such other address as I may hereafter give you in
writing, and all communications so sent, whether by first class mail, postage 
prepaid, telegraph, messenger, or otherwise, shall be deemed given to

<PAGE>
 
me personally, whether actually received or not. Communications sent to me, or
by me, by first class mail postage prepaid, shall be deemed received three
business days after the date posted. Communications sent to me or by me by
telegram shall be deemed received one business day after the date transmitted.

     12. REPRESENTATIONS. If an individual, I represent that I am of the age of
majority as determined by the statutes of the state in which I reside and that I
am not either an employee of any exchange, or of any corporation of which any
exchange owns a majority of the capital stock, or of a member of any exchange,
or of a member firm or a member corporation registered on any exchange, or of a
bank, trust company, insurance company or of any corporation, firm or individual
engaged in the business of dealing, either as broker or as principal, in
securities, or, if I am, that I have obtained the appropriate authorization to
have a margin account as provided by the rules of the New York Stock Exchange,
Inc., if required. If at any time while I have the accounts I become so, I will
immediately notify you in writing. If a corporation, partnership or trust, I
represent that the undersigned has full power to enter into and perform the
obligations hereunder, and that this Agreement has been duly authorized,
executed and delivered. I further represent that no one except me has an
interest on the accounts except as revealed in the title of the account. I
further represent that prior to giving a buy or sell order for property issued
by a corporation or other entity with which I am affiliated, I will disclose
such affiliation to you.

     13. NEW YORK LAW; SUCCESSORS AND ASSIGNS. This agreement and its
enforcement shall be governed by the laws of the state of New York. This
Agreement covers each and every account which I may open or re-open now or in
the future and or continue with you. All transactions made or entered in the
accounts whether before or after the date I execute this Agreement, shall be
treated as though made under and governed by the terms of this Agreement. This
Agreement shall inure to the benefit of your present organization and any
successor or assigns, and shall be binding upon me and my estate executors,
administrators and assigns. Without limiting the generality of your right of
assignment contained in this paragraph, I hereby consent and agree to the
assignment and transfer by you at any future time, resulting from a merger sale
of assets liquidation, or otherwise, of the accounts covered in this Agreement,
including all property, credit and debit balances contained therein to any such
successor organization or assignee and such assignment shall be binding upon me
and my estate executors, administrators and assigns.

     14. CONSENT TO YOUR CREDIT INVESTIGATION. I understand that an
investigation may be made pertaining to my personal and business credit standing
and that I may make written request within a reasonable period of time for
complete and accurate disclosure of its nature and scope.

     15. WAIVERS TO BE IN WRITING. Except as herein otherwise expressly
provided, no provision of this Agreement shall in any respect be waived unless
such waiver is committed to writing and signed by your officer or other
authorized representative. Your failure to insist upon strict compliance with
this Agreement or with any of its terms, or any course of conduct on your part,
shall in no event constitute a waiver by you of any of your rights or privileges
or a creation or acceptance by you of an agency for me or of obligations in my
favor. You shall not be bound by any representation or agreement, oral or
written, heretofore or hereafter made by any of your employees or agents which
in any way purports to affect or diminish your rights or to create or increase
your obligations under this Agreement.

     16. STATEMENT OF CREDIT PRACTICES. All amounts advanced by you and other
balances due to you may be charged with interest pursuant to the terms of your
statement entitled Credit Charges and Margin Requirements, receipt of which is
herein acknowledged. I also agree to pay such other fees and or charges as you
assess to cover your facilities and services, or those of your agents in
accordance with your customary practices at the time of any such charge.

     17. AMENDMENTS. You may from time to time send me amendments to this
Agreement. I understand that each such amendment shall become effective and be
for all purposes considered a part of this Agreement unless I object in writing
to such amendment within ten (10) days after I receive a copy of each such
amendment.
