                                                                 [Draft 3/20/98]

Agreement (the "Securities Loan Agreement") dated April __, 1998 which provides
for loans of certain securities ("Borrowed Securities") by Lender to Borrower
(each a "Loan"); and

        All references to time shall mean the time in effect in New York, New
York.

        All provisions in this Agreement for the transfer, payment or receipt of
funds or cash shall mean transfer of, payment in, or receipt of United States
dollars in immediately available funds.

        2.     Nature and Maintenance of Accounts.

               (a) Borrower and Lender hereby appoint Bank as custodian of all
        Collateral and cash at any time delivered to, and accepted by, Bank in
        connection with this Agreement and as their agent to effect Tri-Party
        Loans as specified in this Agreement. Bank hereby accepts appointment as
        custodian and agent and agrees to establish and maintain Lender's
        Account (as defined below) as provided hereunder.

               (b) Bank maintains a cash account and a securities custody
        account for the benefit of Borrower (collectively, "Borrower's
        Account"). Borrower and Lender instruct Bank to establish and maintain a
        cash custody account and a securities custody account for the benefit of
        Lender (collectively, "Lender's Account"), the Collateral therein which
        is subject to the security interest separately granted by Borrower to
        Lender in the Securities Loan Agreement. Borrower hereby confirms the
        aforementioned security interest and agrees that it includes the
        Collateral in Lender's Account. Bank hereby acknowledges such security
        interest and that Bank will hold all securities, cash or other property
        from time to time deposited in Lender's Account, as bailee on Lender's
        behalf, subject to this Agreement. Bank shall segregate all securities
        and cash in Lender's Account from the assets of Bank or other persons in
        its possession by appropriate identification on the books and records of
        Bank. Bank hereby waives any security interest, lien or right of setoff
        against Lender's Account and the property therein. Bank further
        acknowledges that Bank holds any cash or securities received by Bank
        from Lender in connection with this Agreement as bailee on Lender's
        behalf until credited to Lender's Account, subject to this Agreement.

               (c) The parties intend that the receipt and maintenance by Bank
        of property in Lender's Account shall constitute a bailment under the
        laws of the State of New York and not a debtor-creditor relationship.
        The parties intend to create a special deposit account in favor of
        Lender. Bank shall not pay any interest on any cash held at any time in
        Lender's Account.

               (d) Except as specifically provided in this Agreement, Bank shall
        follow only Borrower's instructions with respect to Borrower's Account
        and shall follow only Lender's instructions with respect to Lender's
        Account.

        3.     Specific Loan Transactions

               (a) On any Business Day on which Borrower and Lender agree to
        enter into a Tri-Party Loan (the "Transaction Date"), Lender will
        deliver the Borrowed Securities to Borrower against the simultaneous
        delivery of cash with a Market Value equal to or greater than [100]% of
        the Market Value of the Borrowed Securities delivered by Lender to
        Borrower. This interim settlement will be accomplished directly by
        Borrower and Lender apart from any action of Bank pursuant to this
        Agreement.

               (b) The further settlement of the transaction will be undertaken
        in the following manner through Bank. On the Transaction Date, (i)
        Lender will transfer cash in an equivalent amount to that received from
        Borrower (the "Cash Amount") to Bank with instructions to Bank to
        deliver the cash to Lender's Account; (ii) Bank will promptly credit
        Lender's Account with such cash; (iii) Borrower will cause Borrower's
        Account to be credited with Collateral; (iv) Borrower will instruct Bank
        to transfer to Borrower's Account the cash held in Lender's Account
        against the transfer to Lender's Account of Collateral held in
        Borrower's Account with a Market Value equal to or greater than the Cash
        Amount and (v) Bank will effectuate Borrower's instructions described in
        clause (iv) by the end of Bank's Business Day.

               (c) On any Business Day on which Borrower or Lender terminates a
        Tri-Party Loan in any manner provided for in the Securities Loan
        Agreement (the "Loan Termination Date"), the party initiating such
        termination shall notify the other party and Bank of the termination of
        the Tri-Party Loan. Alternatively, Borrower may notify Bank of the
        termination of the Tri-Party Loan on behalf of Lender. Bank shall have
        no duty to inquire into whether or not the termination is permitted by
        the Securities Loan Agreement and shall be entitled to rely on Lender's
        or Borrower's notice of termination of the Tri-Party Loan. Unless a
        substitution as described in Section 4(a) hereof of cash Collateral for
        securities Collateral has already occurred, Bank shall on the Loan
        Termination Date, without further instructions, transfer from Lender's
        Account to Borrower's Account all Collateral contained therein against
        the transfer from Borrower's Account to Lender's Account of cash
        Collateral having a Market Value of at least 100% of the Market Value of
        such Collateral (as determined by Bank on the prior Business Day). After
        completion of the transfer, the Collateral returned to Borrower will be
        released from all liens of Lender, and Bank shall without further
        instruction promptly wire to Lender the cash previously transferred to
        Lender's Account. Thereafter, Lender shall wire such cash to Borrower
        against the redelivery of Borrowed Securities by Borrower to Lender
        apart from any action of Bank pursuant to this Agreement.

               (d) If Borrower instructs Bank to identify Collateral on behalf
        of Borrower to be transferred to Lender's Account in connection with
        this Agreement, Bank may select in its sole discretion Collateral from
        Borrower's Account and transfer such Collateral to 



                                       4
<PAGE>   5

        Lender's Account provided such Collateral has the requisite Market Value
        specified in this Agreement.

               (e) Without incurring any liability, Bank may, but shall not be
        obligated to, effectuate (i) any Tri-Party Loan in whole or in part or
        (ii) the termination of a Tri-Party Loan in the event that either Lender
        fails to cause Lender's Account to be credited with the requisite cash
        or Borrower fails to cause Borrower's Account to be credited with the
        requisite cash or Collateral. In any such event, Borrower and Lender
        shall remain obligated to each other pursuant to the terms of the
        Securities Loan Agreement. It is expressly agreed and acknowledged by
        Lender and Borrower that Bank is not guaranteeing performance of or
        assuming any liability for the obligations of Lender or Borrower
        hereunder nor is it assuming any credit risk associated with Tri-Party
        Loans, which liabilities and risks are the responsibility of Lender and
        Borrower; further, it is expressly agreed that Bank is not undertaking
        to make credit available to Borrower or Lender to enable it to complete
        Tri-Party Loans; however, in the event that the cash or securities in
        Borrower's Account is insufficient to satisfy a required delivery of
        cash or securities to Lender or Lender's Account, Bank may at its
        option, (i) without further notice to Borrower, advance the amount of
        the insufficiency on Borrower's behalf in which case Borrower shall be
        obligated to repay such amount to Bank, plus interest at a rate to be
        determined from time to time, or (ii) not effectuate the transaction and
        promptly notify Lender and Borrower. Notwithstanding the fact that Bank
        may from time to time make advances or loans pursuant to this paragraph
        or otherwise extend credit to Borrower, whether or not as a regular
        pattern, Bank may at any time decline to extend such credit for any
        reason, including, but not limited to, if Bank believes Borrower to be
        insecure or Bank believes Borrower's ability to perform its obligations
        hereunder may be impaired, or if Bank is precluded from extending such
        credit as a result of any law, regulation or applicable ruling.
        Notwithstanding anything in this Agreement to the contrary, Bank shall
        not be obligated to transfer from Borrower's Account to Lender's Account
        any cash or securities which it has a right not to transfer pursuant to
        any other agreement between Borrower and Bank.

               (f) Bank shall be responsible for verifying that all securities
        and/or cash transferred to Lender's Account as Collateral fits within
        the definition of "Collateral" as specified in this Agreement and that
        physical securities are in negotiable form.

               (g) Borrower and Lender agree that in effecting Tri-Party Loans,
        transfers between Borrower's Account and Lender's Account, including,
        without limitation, substitutions, are intended to be, and shall be
        deemed to be, simultaneous.

        4.     Substitutions



                                       5
<PAGE>   6

               (a) Bank may, on each Business Day at Borrower's request and
        without the prior consent of or notification to Lender, transfer from
        Lender's Account to Borrower's Account any or all Collateral contained
        therein against the transfer from Borrower's Account to Lender's Account
        of cash Collateral having a Market Value of at least 100% of the Market
        Value of such Collateral (as determined by Bank on the prior Business
        Day) ("IntraDay Cash Collateral"). In such case, by the end of the
        Business Day, Borrower shall instruct Bank to transfer to Lender's
        Account from Borrower's Account Collateral having a Market Value
        (determined by Bank on that Business Day) equal to or greater than the
        IntraDay Cash Collateral (as such value has been subsequently increased
        or decreased that Business Day pursuant to Section 5 hereof) against the
        transfer from Lender's Account to Borrower's Account of the IntraDay
        Cash Collateral (as such value has been subsequently increased or
        decreased that Business Day pursuant to Section 5 hereof).

               (b) Lender hereby authorizes Bank, from time to time at
        Borrower's request and without the prior consent of or notification to
        Lender, to release to Borrower Collateral from Lender's Account against
        the transfer to Lender's Account of other Collateral provided that the
        Collateral in Lender's Account after the substitution has a Market Value
        equal to or greater than the Market Value of the Collateral in Lender's
        Account immediately before the substitution. Notwithstanding the
        foregoing, the Market Value of the Collateral in Lender's Account after
        the substitution need not be any greater than the Intraday Cash
        Collateral in Lender's Account on that Business Day (as such value has
        been subsequently increased or decreased that Business Day pursuant to
        Section 5 hereof).

        5. Mark-to-Market. Borrower shall mark-to-market the Borrowed Securities
in the manner provided in the Securities Loan Agreement apart from any action of
Bank. If Borrower is required to furnish additional Collateral to Lender as a
result of the mark-to-market process, Borrower shall satisfy that requirement by
instructing Bank on a Business Day to transfer from Borrower's Account to
Lender's Account Collateral with a Market Value equal to the amount specified in
Borrower's instructions. If Lender is required to return Collateral to Borrower
as a result of the mark-to-market process, Lender hereby authorizes Borrower to
satisfy that requirement by instructing Bank on a Business Day to transfer
Collateral from Lender's Account to Borrower's Account with a Market Value equal
to the amount specified in Borrower's instructions. Bank shall effectuate each
such instruction by no later than the end of the Business Day on which it
received the instruction. Bank shall not be required to make any independent
determination concerning the validity of any mark-to-market instruction and
shall be entitled, without any liability to Bank, to rely on Borrower's
instructions.

        6. Income. Bank shall credit to Borrower's Account all Income paid by or
on behalf of issuers in respect of the Collateral in the event that any such
amounts are received by Bank. 



                                       6
<PAGE>   7

Notwithstanding the foregoing, in the event Bank receives a written notice from
Lender of an Event of Default by Borrower, Bank shall credit such amounts to
Lender's Account.

        7. Lender's Account. Until the earlier of the Loan Termination Date or
the date, if any, when Bank shall receive a written notice of an Event of
Default from Lender or Borrower pursuant to Section 12 hereof, Lender hereby
instructs Bank to hold the Collateral in Lender's Account and to refuse to act
upon any instructions of Lender or Borrower to deliver the Collateral other than
as expressly provided in this Agreement. Except as provided in Section 12 hereof
and other sections hereof authorizing Collateral to be transferred into or out
of Lender's Account, Lender further agrees that unless Lender shall receive the
written consent of Borrower and Borrower confirms Borrower's consent to Bank,
Lender shall not sell, transfer, assign, pledge or otherwise utilize or transfer
the Collateral held in Lender's Account.

        8. Daily Statement. On each Business Day, Bank shall send to Borrower
and Lender a statement describing the Collateral held in Lender's Account as of
the close of the prior Business Day. Such statement shall include a statement of
the Market Value of such securities and/or cash as of the prior Business Day.
Notwithstanding the foregoing, no statement will be sent if there are no
securities or cash in Lender's Account as of the close of the prior Business
Day. Lender and Borrower shall promptly review all such statements and shall
promptly advise Bank of any error, omission or inaccuracy in the cash or
Collateral positions reported. Bank shall undertake to correct any errors,
failures or omissions that are reported to Bank by Lender or Borrower to the
extent possible. Any such corrections shall be reflected on subsequent
statements.

        9. Care of Property; Reliance on Instructions; and Pricing of Securities

               (a) Bank shall exercise the same care with respect to property in
        Borrower's Account and Lender's Account as Bank exercises with respect
        to Bank's own property. Bank assumes responsibility only for loss to any
        such property of Lender or Borrower occasioned by the negligence of, or
        conversion, misappropriation, theft or other willful misconduct by
        Bank's employees. Bank's liability for lost securities shall be limited
        to the Market Value thereof at the date of the discovery of such loss.
        Notwithstanding anything to the contrary contained in this Agreement, in
        no event shall Bank be liable for special, consequential, or indirect
        damages even if Bank has been advised as to the possibility thereof and
        regardless of the form of action. Bank, at its option, may insure itself
        against loss from any cause but shall be under no obligation to obtain
        insurance directly for the benefit of either Borrower or Lender. In
        matters concerning or relating to this Agreement, Bank shall not be
        responsible for compliance with any statute or regulation regarding the
        establishment or maintenance of margin credit, including but not limited
        to Regulations T or X of the Board of Governors of the Federal Reserve
        System, or with any rules or regulations of the Office of the Controller
        of the Currency. Bank shall not be liable for any acts or omissions of
        the other parties to this Agreement. Bank 



                                       7
<PAGE>   8

        shall not have any duty to require that any cash or securities be
        delivered to it or to determine that the amount and form of assets
        deposited in the accounts comply with any applicable requirements other
        than as specified in this Agreement.

               (b) Bank, at any time, without any resulting liability to it, may
        act hereunder in reliance upon any instructions or notices Bank
        reasonably believes to be genuine; provided, however, that all
        instructions and notices to Bank shall be by a signed writing (via
        telecopy, or otherwise), by electronic communication or by oral
        communication, including the code which may be assigned by Bank to
        Lender from time to time. Instructions to Bank from Borrower may also be
        given in the manner specified in the Clearance Agreement between Bank
        and Borrower. Bank reserves the right to confirm payment orders and/or
        institute any other reasonable security procedures to verify payment
        orders.

               (c) Until written notice to the contrary is given to another
        party to this Agreement by Lender and such other party has had a
        reasonable time to amend its records, such other party shall be entitled
        to act on the belief that the persons listed on Schedule 2 hereto,
        whether or not any such person is an officer or employee of Lender, and
        any other person who Bank reasonably and in good faith believes is
        authorized to act on behalf of Lender, are authorized to act on behalf
        of Lender, and that any one of them has authority to transfer
        Collateral, hold Collateral, give notices and otherwise act under this
        Agreement on behalf of Lender.

               (d) Bank may rely upon a recognized pricing service (or its
        equivalent as provided in the definition of Market Value) or a
        recognized credit rating service in determining the Market Value or
        credit ratings of the Collateral, as applicable, and shall in no
        circumstances be liable for any errors made by such service.

               (e) All credits, debits or transfers shall be deemed to have been
        completed at such time as recorded on Bank's books.

               (f) All transfers of securities and cash between Bank and Lender
        shall be made to the accounts listed on Schedule 2 hereto unless
        otherwise agreed between Lender and Bank.

               (g) Bank undertakes to perform only such duties as are expressly
        set forth in this Agreement.

               (h) Transfer of securities to Bank hereunder may be accomplished
        by crediting a proprietary or pledgee account of Bank with the Federal
        Reserve Bank of New York ("FRBNY"), The Participants Trust Company
        ("PTC"), The Depository Trust Company ("DTC") or other clearing
        corporation or depository legally available to Bank 



                                       8
<PAGE>   9

        (each, a "Clearing Corporation"), as the case may be, or by delivery of
        physical certificates to Bank in negotiable form. Borrower and Lender
        agree that Bank's use of a Clearing Corporation in connection with
        Tri-Party Loans contemplated under this Agreement is authorized and
        shall fully comply with all terms and conditions of this Agreement
        regarding Bank's transfer and custody of securities and cash. Lender and
        Borrower acknowledge and understand that all transfers of securities or
        cash by a Clearing Corporation, as the case may be, will be subject to
        the then applicable rules and procedures of such Clearing Corporation.
        No Clearing Corporation shall be deemed to be an agent of Bank, and Bank
        shall have no liability for the acts or omissions of any Clearing
        Corporation. Notwithstanding anything to the contrary contained in this
        Agreement, Bank shall be authorized, in its reasonable discretion, to
        accept a trust receipt as Collateral.

               (i) Bank is not a party to the Securities Loan Agreement. Bank's
        obligations hereunder shall not be affected by, nor does Bank assume any
        liability under, the Securities Loan Agreement.

               (j) Bank shall not be deemed to have independent knowledge or
        notice of the existence of an Event of Default. Bank shall be entitled
        to rely on Lender's or Borrower's written notice (including, without
        limitation, facsimile notice) thereof and shall have no duty to inquire
        into the nature or validity of an Event of Default.

               (k) Bank may, with respect to questions of law, apply for and
        obtain the advice and opinion of counsel and shall not be deemed to be
        negligent or have engaged in willful misconduct in any action taken or
        omitted by Bank in good faith in conformity with such advice or opinion.

               (l) Without limiting the generality of the foregoing, Bank shall
        be under no obligation to inquire into, and shall not be liable for:

                        (i) subject to Section 3(f) hereof, the title, validity
                or genuineness of any Collateral or document;

                        (ii) the legality of the lending or borrowing of any
                Collateral or the propriety of the amount of a Tri-Party Loan or
                the enforceability of any Trust Receipt received by Bank
                pursuant to this Agreement;

                        (iii) the due authority of any person (listed on
                Schedule 2 hereto with respect to Lender) to act on behalf of
                Lender with respect to cash or Collateral held in Lender's

                        (iv) the due authority of Lender, Borrower or any
                entities for which Lender acts to deliver, transfer, obtain or
                hold any particular Collateral pursuant to this Agreement.

        10. Compensation. Borrower hereby agrees to pay Bank compensation for
the services to be rendered hereunder, based upon rates which shall be
determined from time to time in a manner agreed upon by Bank and Borrower.

        11. Indemnification. Borrower hereby agrees to indemnify Bank for, and
hold it harmless against, any loss, liability or expense in connection with,
arising out of or in any way related to the transactions contemplated and
relationship established by this Agreement or the Securities Loan Agreement, or
any action or omission by Bank in connection with this Agreement, including the
reasonable costs, expenses and attorneys fees of attorneys chosen by Bank
incurred in defending any such claim of liability, except that Borrower shall
not be liable for any loss, liability or expense that is determined to be the
direct result of acts or omissions on the part of Bank constituting negligence
or willful misconduct. These indemnification obligations shall survive the
termination of any Loan, Tri-Party Loan, the Securities Loan Agreement, this
Agreement or all of them. For purposes of this Section, "Bank" shall mean Bank,
any existing or future parent company of Bank, any existing or future direct or
indirect subsidiary of such parent company and any director, officer, employee
or agent of any of the foregoing.

        12. Event of Default; Continuing Disputes; Effect of Notice of Levy,
Etc.

               (a) If either Lender or Borrower shall declare an Event of
        Default, it shall deliver a written notice of an Event of Default to
        Bank and to the other party. Such notice shall identify the name of the
        defaulting party, the Event of Default and the Tri-Party Loan(s) which
        are the subject of such Event of Default. Bank shall notify the
        defaulting party of Bank's receipt of a written notice of an Event of
        Default.

               (b) From and after Bank's receipt of a written notice of an Event
        of Default from Lender or Borrower, Bank shall continue to hold all
        Collateral in Lender's Account. Bank shall cease performing its normal
        duties in connection with the Tri-Party Loan(s) which are the subject of
        such Event of Default and shall await instructions as described below.
        In the absence of any dispute between, conflicting claims by or
        conflicting instructions from Borrower, Lender and any other person with
        respect to the Collateral or any other matter covered by this Agreement
        and if Bank, in the opinion of its counsel, is permitted by law to do
        so, Bank is hereby instructed to follow the instructions of the
        non-defaulting party with respect to the non-defaulting party's Account,
        and Bank is hereby further instructed to follow the instructions of
        Borrower to accept into Lender's Account cash Collateral in substitution
        of any Collateral therein as provided in Section 4(a) hereof.

               (c) In the event of any dispute between, conflicting claims by or
        conflicting instructions from Borrower, Lender and any other person with
        respect to the Collateral, cash or any other matter covered by this
        Agreement or if Bank, in the opinion of its counsel, is precluded by law
        from acting, Bank may decline to comply with any and all claims, demands
        or instructions with respect to such Collateral, cash or any other
        matter covered by this Agreement so long as such dispute or conflict or
        legal inability to perform shall continue, and Bank shall not be liable
        for failure to act or to comply with such claims, demands or
        instructions. Bank shall be entitled to refuse to act or comply until
        (i) such dispute or conflict shall have been finally determined in a
        court of competent jurisdiction or settled by agreement between the
        conflicting parties and Bank shall have received evidence satisfactory
        to it of the same, (ii) Bank, in the opinion of its counsel, is
        permitted by law to perform or (iii) Bank shall have received security
        or an indemnity satisfactory to it sufficient to hold it harmless from
        and against any and all losses or damages, including reasonable
        counsel's fees and expenses that it may incur by reason of taking any
        action.

               (d) If Bank shall be uncertain as to its duties or rights
        hereunder, it shall be entitled to refrain from taking any action until
        (i) Bank shall be directed otherwise in writing by Lender and Borrower
        or by a final order or judgment of a court of competent jurisdiction or
        (ii) Bank shall have received security or an indemnity satisfactory to
        it sufficient to hold it harmless from and against any and all losses or
        damages, including reasonable counsel's fees and expenses that it may
        incur by reason of taking any action.

               (e) Bank shall not be required to deliver or transfer cash or
        securities in contravention of any order, judgment, levy, restraining
        notice, seizure or other similar notice issued or directed by a
        governmental agency or court, or officer thereof, asserting jurisdiction
        over Bank, any existing or future parent company of Bank, any existing
        or future direct or indirect subsidiary of such parent company or any
        director, officer, employee or agent of any of the foregoing, which on
        its face affects such cash or securities. Bank shall give Lender and
        Borrower prompt notice of any such notice or order.

               (f) Bank's receipt of a notice of an Event of Default by itself
        shall not be considered to be a dispute or conflict for purposes of this
        Section 12 of this Agreement.

        13. Funds Transfer Name/Identifying Number Inconsistencies. In executing
or paying a payment order, Bank may rely upon the identifying number (e.g.
Fedwire routing number or account number) of any party as instructed in the
payment order. Borrower assumes full responsibility for any inconsistency
between the name and identifying number of any party in payment orders issued to
Bank in Borrower's name. Lender assumes full responsibility for any
inconsistency between the name and identifying number of any party in payment
orders issued to Bank in Lender's name.
