this Agreement, be either in the form of a Base Rate Loan or a LIBOR Loan;
provided, however, that in no event shall the Borrower maintain at any time
LIBOR Loans having more than four (4) different Interest Periods. The Borrower
shall repay the principal amount of the Loans in the amounts and in the manner

                  (f) PERMITTED USES OF LOAN PROCEEDS. The Borrower shall use
the Loan proceeds only for the purposes of funding working capital, general
short-term corporate needs and Investments expressly permitted under this
Agreement.

                  (g) LETTER OF CREDIT SUBLIMIT UNDER REVOLVING CREDIT FACILITY.
Without limiting the generality of the foregoing, each Lender severally agrees
that a Responsible Person of the Borrower may, by delivery of notice to the
Agent in accordance with SECTION 2.5, also request the Issuing Bank to issue one
or more standby or documentary letters of credit under the Letter of Credit
Commitment for the account of the Borrower, which letters of credit shall be in
the standard form of the Issuing Bank (each a "Letter of Credit"); in which
event, after satisfaction of all conditions precedent set forth in SECTION 4.2,
the Issuing Bank shall issue such Letters of Credit subject to and in accordance
with SECTION 2.1.2; provided, however, nothing contained in this Agreement shall
under any circumstance be deemed to require the Issuing Bank to issue any Letter
of Credit which, taking into account the issuance of such Letter of Credit,
would either cause the Letter of Credit Undrawn Amount to exceed the Letter of
Credit Commitment or cause the aggregate principal amount of the Loans then
outstanding plus the Letter of Credit Undrawn Amount to exceed the Revolving
Credit Availability."

            2.1.2 LETTER OF CREDIT SUBFACILITY.

                  (a) Subject to the terms and conditions of this Agreement and
in reliance upon the representations and warranties of the Borrower set forth
herein, at any time and from time to time from the Closing through the Business
Day immediately prior to the Revolving Credit Maturity Date, after satisfaction
of all conditions precedent set forth in SECTION 4.2, the Issuing Bank shall
issue for the account of the Borrower Letters of Credit in minimum amounts not
less than $100,000, provided that a request shall have been made for such
Letters of Credit by a Responsible Person of the Borrower delivering to the
Agent a Borrowing Notice, duly executed with appropriate insertions and as
otherwise required by SECTION 2.5, together with a duly executed Letter of
Credit Application, with appropriate insertions (which Borrowing Notice and
Letter of Credit Application shall have been received by the Issuing Bank prior
to 10:00 a.m., San Jose, California time, five (5) Business Days prior to the
requested issuing date), after consultation with Lenders and receiving the
consent of Requisite Lenders. No Letter of Credit shall have an expiration date
that is later than one hundred twenty (120) days after the Revolving Credit
Maturity Date or one (1) year after the issuance of such Letter of Credit (or
any renewal thereof), whichever is earlier.

                  (b) Upon issuance of each Letter of Credit, each Lender shall
be deemed to have purchased a participation from the Issuing Bank equal to such
Lender's Pro Rata Share of the original stated amount of such Letter of Credit.
Nothing contained in this Agreement shall under any circumstance be deemed to
require any Lender to participate in the issuance of any Letter of Credit which,
taking into account such Lender's participation in such Letter of Credit, when
added to the aggregate of such Lender's participation in all other issued and
undrawn Letters of Credit, exceeds such Lender's Pro Rata Share of the Letter of
Credit Commitment.

                  (c) Unless otherwise expressly provided therein, each
beneficiary named by the Borrower with respect to a Letter of Credit issued
hereunder shall be permitted to make full or partial draws under such Letter of
Credit. Upon the making of any draw under a


                                       20


<PAGE>   22
Letter of Credit by such beneficiary, the full amount of such draw shall be
immediately due and payable by the Borrower to the Issuing Bank. The Issuing
Bank shall immediately give written notification of the amount of such draw to
the Agent, each Lender and the Borrower and to the extent that the Issuing Bank
has not been immediately reimbursed by the Borrower for any payment required to
be made by the Issuing Bank under such Letter of Credit (and all commissions
incurred but unpaid in connection therewith), each Lender shall, according to
its Pro Rata Share of such Letter of Credit, reimburse the Issuing Bank
immediately upon written demand for the amount of such payment (and such unpaid
commissions). The obligation of each Lender to so reimburse the Issuing Bank
shall be absolute and unconditional and shall not be affected by the occurrence
of a Potential Event of Default or Event of Default or any other occurrence or
event. Any such reimbursement shall not relieve or otherwise limit or impair the
obligation of the Borrower to reimburse the Lenders for the amount of any
payment made by the Issuing Bank under any Letter of Credit.

                  (d) Without limiting the generality of the preceding
subsections of this SECTION 2.1.2, in the event the Borrower shall fail to
reimburse immediately the Issuing Bank for any honor of a draw on any Letter of
Credit as confirmed by the Issuing Bank's written notice and demand for payment
from each Lender of its ratable participation amount pursuant to SECTION
2.1.2(C), each Lender shall be deemed to have made, without further notice to
the Borrower, a Base Rate Loan in the principal amount equal to such Lender's
Pro Rata Share of the amount drawn under such Letter of Credit (plus any unpaid
commission); and, for this purpose, the conditions precedent set forth in
SECTION 4.2 shall not apply. Any Base Rate Loan deemed to be advanced after the
Revolving Credit Maturity Date, shall be immediately due and payable. The
proceeds of such Base Rate Loans shall be applied to reimburse the Issuing Bank
for such payment required to be made by the Issuing Bank under the Letter of
Credit. In the event that any Base Rate Loan shall be deemed to be made to the
Borrower pursuant to this SECTION 2.1.2(D), such Base Rate Loan shall be deemed
to have been made as of the date of the honor of the draw under the respective
Letter of Credit and interest shall accrue thereon at the same rate as provided
for other Base Rate Loans under this Agreement. In the event that the Issuing
Bank does not receive the proceeds of any Base Rate Loans made pursuant to this
subsection by 12:00 noon, San Jose, California time, on the date that the draw
on the Letter of Credit is honored, the Lender whose funds are delayed shall pay
interest to the Issuing Bank on the amount not received at the Federal Funds
Rate from the date of such honor until the date on which the Issuing Bank
receives such proceeds by 12:00 noon.

                  (e)(1) The Issuing Bank may resign as Issuing Bank by giving
notice to the Agent, the Lenders and the Borrower on or before April 30 of any
calendar year, and such resignation shall be effective as to any Letter of
Credit outstanding on May 31 of such calendar year upon the then current expiry
date on such Letter of Credit. If the Issuing Bank shall resign as the Issuing
Bank under this Agreement, Requisite Lenders shall appoint a successor Issuing
Bank from among the Lenders, with the consent of such successor.

                    (2) If an Issuing Bank has resigned and no successor Issuing
Bank is appointed prior to such May 31, then until an appointment of a successor
Issuing Bank is made, in the event of a request by the Borrower for the issuance
of a Letter of Credit under


                                       21


<PAGE>   23
SECTION 2.1.1, each Lender shall issue its own Letter of Credit in an amount
equal to such Lender's Pro Rata Share of the amount of such requested Letter of
Credit upon the terms and conditions set forth in SECTIONS 2.1.1 and 2.1.2, with
such changes as are appropriate to apply to an individual Lender issuing a
Letter of Credit without participation. In the event of an unreimbursed draw on
a Letter of Credit issued pursuant to the provisions of this SECTION
2.1.2(E)(2), each Lender which has honored such a draw shall be deemed to have
made a Base Rate Loan to reimburse itself for the draw under such Letter of
Credit.

                    (3) During any period while there is no Issuing Bank, the
reference to Issuing Bank in SECTION 11.2 shall be deemed to be deleted except
to the extent that any Letter of Credit remains outstanding which has been
issued by the resigning Issuing Bank. With respect to any Letter of Credit
issued under SECTION 2.1.2(E)(2), the reference to "Issuing Bank" in SECTION
2.8(D) shall be to each Lender issuing a Letter of Credit and all fees due
(including the fee payable to the Issuing Bank) under SECTION 2.8(B) shall be
payable to the Lenders according to their respective Pro Rata Shares of the
Aggregate Commitments.

                    (4) Upon the acceptance of its appointment as a successor
Issuing Bank hereunder, such successor Issuing Bank shall succeed to all the
rights, powers and duties of the retiring Issuing Bank with respect to any
Letters of Credit issued subsequent to such acceptance, and the term "Issuing
Bank" shall mean such successor issuing bank with regard to such subsequently
issued Letters of Credit. Whether or not a successor Issuing Bank is appointed,
the retiring Issuing Bank shall retain all the rights, powers and duties of an
Issuing Bank with respect to any Letters of Credit previously issued by such
retiring Issuing Bank, and the term "Issuing Bank" shall mean such retiring
Issuing Bank with respect to such previously issued Letters of Credit.

                  (f) The obligation of the Borrower to reimburse the Lenders
for drawings made under the Letters of Credit shall be absolute, unconditional
and irrevocable, and shall be performed strictly in accordance with the terms of
this Agreement and such Letters of Credit, under all circumstances whatsoever,
including the following circumstances:

                    (1) Any lack of validity or enforceability of any Letter of
Credit, the obligation supported by such Letter of Credit or any other agreement
or instrument relating thereto (collectively, the "Related LC Documents");

                    (2) Any amendment or waiver of or any consent to or
departure from all or any of the Related LC Documents;

                    (3) The existence of any claim, set-off, defense or other
rights which the Borrower may have at any time against any beneficiary or any
transferee of any Letter of Credit (or any Persons or entities for whom any such
beneficiary or any such transferee may be acting), the Lenders, the Agent or any
other Person, whether in connection with the Loan Documents, the Related LC
Documents or any unrelated transaction;

                    (4) Any breach of contract or other dispute between the


                                       22


<PAGE>   24
Borrower and any beneficiary or any transferee of any Letter of Credit (or any
Persons or entities for whom such beneficiary or any such transferee may be
acting), the Lenders, the Agent or any other Person;

                    (5) Any draft, statement or any other document presented
under any Letter of Credit proving to be forged, fraudulent, invalid or
insufficient in any respect or any statement therein being untrue or inaccurate
in any respect whatsoever; or

                    (6) Any delay, extension of time, renewal, compromise or
other indulgence or modification granted or agreed to by the Issuing Bank, with
or without notice to or approval by the Borrower in respect of any of the
Borrower's Indebtedness under this Agreement.

                  (g) The Borrower assumes all risks of the acts or omissions of
any beneficiary and any transferee of each Letter of Credit; provided, however,
this assumption with respect to the Agent and the Lenders, including the Issuing
Bank, is not intended to, and shall not, preclude the Borrower's pursuing such
rights and remedies as it may have against any such beneficiary or transferee of
a Letter of Credit at law or under any other agreement. Neither the Agent nor
any Lender, including the Issuing Bank, nor any of their officers or directors
shall be liable or responsible for, without limitation: (1) the use which may be
made of any Letter of Credit or for any acts or omissions of any beneficiary and
any transferee of any Letter of Credit in connection therewith; or (2) the
validity, sufficiency or genuineness of documents, or of any endorsement(s)
thereon, even if such documents should in fact prove to be in any or all
respects invalid, insufficient, fraudulent or forged. In furtherance and not in
limitation of the foregoing, the Issuing Bank may accept documents that appear
on their face to be in order, without responsibility for further investigation,
regardless of any notice or information to the contrary.

                  (h) Subject to the laws, customs and practices of the trade in
the area where the beneficiary is located and to the extent not otherwise
inconsistent with the provisions of this SECTION 2.1.2, each Letter of Credit
will be subject to, and performance under each Letter of Credit by the Issuing
Bank, its correspondents, and the beneficiary will be governed by, UCC Article 5
and the "Uniform Customs and Practice for Documentary Credit (1993 Revision),
International Chamber of Commerce, Publication No. 500," or by any later Uniform
Customs and Practice fixed by later Congresses of the International Chamber of
Commerce as in effect on the date the Letter of Credit is issued; provided,
however, that to the extent any conflict exists between UCC Article 5 and such
Uniform Customs and Practices then in effect, UCC Article 5 shall control.

        2.2 NOTES.

                  (a) NOTES. The Loans made by each Lender shall be evidenced by
separate Notes executed by the Borrower and made payable to the order of such
Lender in the stated principal amount equal to its Commitment.

                  (b) NOTATIONS IN LENDERS' BOOKS AND RECORDS. Each Lender shall
make


                                       23


<PAGE>   25
notations in its books and records regarding the date, amount and maturity of
each Loan made by it and the amount of each repayment or prepayment of principal
and payment of interest made by the Borrower with respect to such Loan. Each
Lender is irrevocably authorized by the Borrower to endorse its Note and each
Lender's record shall constitute a rebuttable presumption as to the matters set
forth therein; provided, however, that the failure of a Lender to make, or an
error in making, such a notation with respect to any Loan shall not limit or
otherwise affect the Obligations of the Borrower hereunder or under any such
Note to such Lender.

        2.3 REPAYMENT OF THE LOANS. Subject to the terms of this Agreement
relating to mandatory permanent reductions of the Aggregate Commitments,
mandatory prepayments of the Loans and the acceleration of maturities by the
Lenders, the Borrower shall repay the Lenders the entire outstanding principal
amount of the Loans and all other unpaid amounts outstanding under the Revolving
Credit Facility on the Revolving Credit Maturity Date.

        2.4 PAYMENT OF INTEREST ON THE LOANS.

            (a) INTEREST RATES. Subject to SECTION 2.4(D) of this Agreement,
each Loan shall bear interest on the outstanding principal amount thereof from
the date when made, continued or converted until paid in full at a rate per
annum equal to the Base Rate or the Adjusted LIBOR plus the Applicable Margin,
as the case may be.

            (b) INTEREST PAYMENT DATES. Interest on each Loan shall be paid in
arrears on each Interest Payment Date. Interest shall also be paid on the date
of any prepayment of any Loans pursuant to this Agreement for the portion of the
Loans so prepaid and upon payment (including prepayment) in full thereof.

            (c) INTEREST UPON EVENTS OF DEFAULT. Upon the occurrence of an Event
of Default and so long as such Event of Default shall continue, including after
acceleration (whether before or after entry of judgment), the Borrower shall, at
the option of Requisite Lenders, pay interest on the principal amount of each
Loan then outstanding at a rate per annum which is determined by adding three
percent (3.00%) to the interest rate otherwise applicable to such Loan.

            (d) LIMITATIONS ON INTEREST RATES. Notwithstanding any provision in
this Agreement, the Notes or any of the other Loan Documents, the total
liability for payments in the nature of interest shall not exceed the applicable
limits imposed by any applicable federal or state interest rate laws. If any
payments in the nature of interest, additional interest and other charges made
hereunder or under any of the Loan Documents are held to be in excess of the
applicable limits imposed by any applicable federal or state law, the amount
held to be in excess shall be considered payment of principal under the Notes
and the indebtedness evidenced thereby shall be reduced by such amount in the
inverse order of maturity so that the total liability for payments in the nature
of interest, additional interest and other charges shall not exceed the
applicable limits imposed by any applicable federal or state interest rate laws.

<PAGE>   26
        2.5 PROCEDURE FOR THE BORROWING OF LOANS.

            (a) Each Borrowing of Loans shall be made upon the Borrower's
irrevocable written notice delivered to the Agent in the form of a Borrowing
Notice, executed by a Responsible Person of the Borrower, with appropriate
insertions (which Borrowing Notice must be received by the Agent prior to 10:00
a.m., San Jose, California time, (i) three (3) Business Days prior to the
requested Funding Date, in the case of LIBOR Loans, and (ii) on the requested
Funding Date, in the case of Base Rate Loans), specifying:

                (A) the amount of the Borrowing, which shall be in integral
            multiples of One Hundred Thousand Dollars ($100,000) and, if LIBOR
            Loans are requested, in an aggregate minimum principal amount of Two
            Million Dollars ($2,000,000);

                (B) the requested Funding Date, which shall be a Business Day;

                (C) whether the Borrowing is to be comprised of LIBOR Loans or
            Base Rate Loans;

                (D) the duration of the Interest Period applicable to any such
            LIBOR Loans included in such notice. If the Borrowing Notice shall
            fail to specify the duration of the Interest Period for any
            Borrowing comprised of LIBOR Loans, such Interest Period shall be
            deemed to be one (1) month; and

                (E) the Designated Deposit Account into which proceeds of the
            Loans are to be transferred, together with wiring instructions.

            (b) Upon receipt of the Borrowing Notice, the Agent will promptly
notify each Lender having a Commitment of the amount of such Lender's Pro Rata
Share of the requested Borrowing.

            (c) Each Lender will make the amount of its Pro Rata Share of the
Borrowing available to the Agent for the account of the Borrower at the Agent's
Payment Office by 12:00 noon, San Jose, California time, on the Funding Date
requested by the Borrower in funds immediately available to the Agent. The
proceeds of all such Loans will then be made available to the Borrower on the
Funding Date by the Agent by wire transfer to the Designated Deposit Account
specified in the Borrowing Notice. No Borrowing of Loans shall be deemed made to
the Borrower, and no interest shall accrue on any such Borrowing, until the
related funds have been deposited in the Designated Deposit Account.

            (d) Unless all Lenders having a Commitment shall otherwise consent,
during the existence of a Potential Event of Default or Event of Default, the
Borrower may not elect to have a Loan made as a LIBOR Loan.


                                       25


<PAGE>   27
        2.6 CONVERSION AND CONTINUATION ELECTIONS.

            (a) The Borrower may upon irrevocable written notice from the
Borrower to the Agent:

                  (i) elect to convert on any Business Day, Base Rate Loans in
an amount equal to Two Million Dollars ($2,000,000) or any integral multiple of
$100,000 in excess thereof, into LIBOR Loans; or

                  (ii) elect to convert on any Interest Payment Date any LIBOR
Loans maturing on such Interest Payment Date into Base Rate Loans; or

                  (iii) elect to continue on any Interest Payment Date any LIBOR
Loans maturing on such Interest Payment Date (or any part thereof in an amount
equal to Two Million Dollars ($2,000,000) or any integral multiple of $100,000
in excess thereof).

            (b) The Borrower shall deliver a Conversion/Continuation Notice in
accordance with SECTION 12.4 of this Agreement to be received by the Agent prior
to 10:00 a.m., San Jose, California time, at least (i) three (3) Business Days
in advance of the conversion date or continuation date, if any Loans are to be
converted into or continued as LIBOR Loans; and (ii) on the conversion date, if
any Loans are to be converted into Base Rate Loans; specifying:

                (A) the proposed Conversion Date or Continuation Date;

                (B) the aggregate amount of Loans to be converted or continued;

                (C) the nature of the proposed conversion or continuation; and

                (D) the duration of the requested Interest Period.

            (c) If upon the expiration of any Interest Period applicable to any
LIBOR Loans, the Borrower shall have failed to have given due notice to the
Agent of the Borrower's selection of a new Interest Period to be applicable to
such LIBOR Loans, the Borrower shall be deemed to have elected to convert such
LIBOR Loans into Base Rate Loans.

            (d) Upon receipt of a Conversion/Continuation Notice, the Agent will
promptly notify each Lender thereof, or, if no timely notice is provided by the
Borrower, the Agent will promptly notify each Lender of the details of any
automatic conversion. All conversions and continuations shall be made according
to each Lender's applicable Pro Rata Share of the outstanding principal amounts
of the Loans with respect to which the notice was given.

            (e) Unless all Lenders shall otherwise consent, during the existence
of a Potential Event of Default or an Event of Default, the Borrower may not
elect to have a Loan converted into or continued as a LIBOR Loan.

<PAGE>   28
        2.7 VOLUNTARY REDUCTION IN AGGREGATE COMMITMENTS. Subject to this
SECTION 2.7 and SECTION 3.5, the Borrower may, at any time and from time to
time, elect to permanently reduce the Aggregate Commitments by delivering to the
Agent written notice thereof (a "Prepayment Notice"); provided, however, that
any such reduction shall commensurately reduce the Letter of Credit Commitment.
The Prepayment Notice shall (a) specify the date and amount of such reduction
and (b) in the event such proposed reduction in the Aggregate Commitments would,
pursuant to this Agreement, give rise to the requirement that the Borrower
prepay any of the Loans in order to comply with the Revolving Credit
Availability, then such notice shall (i) state whether such prepayment is to be
applied to Base Rate Loans or LIBOR Loans, or any combination thereof, and (ii)
if such prepayment consists solely of Base Rate Loans, the Prepayment Notice
shall be delivered to the Agent at least one (1) Business Day prior to the
effective date for such proposed reduction in the Aggregate Commitments, or, if
such prepayment (or any portion thereof) consists of LIBOR Rate Loans, the
Prepayment Notice shall be delivered to the Agent at least three (3) Business
Days prior to the effective date for such proposed reduction in the Aggregate
Commitments. Such notice shall be irrevocable and the Agent shall promptly
notify each Lender thereof and of such Lender's Pro Rata Share of such reduction
in the Aggregate Commitments and, as applicable, prepayment of Loans. Any
prepayment of Loans required to be made by the Borrower pursuant to a reduction
in the Aggregate Commitments shall be due and payable on the effective date for
such reduction, together with accrued interest to such date on the principal
amount prepaid and any amounts required pursuant to SECTION 3.5 of this
Agreement, but otherwise without premium or penalty. Notwithstanding anything to
the contrary, any prepayments pursuant to this SECTION 2.7 shall be applied
first to any Base Rate Loans then outstanding and then to LIBOR Loans with the
shortest Interest Periods remaining.

        2.8 FEES.

            (a) CLOSING FEE. In consideration hereof, the Borrower agrees to pay
fees upon the Closing as set forth in the Fee Letter to the Lenders that are
original signatories to this Agreement.

            (b) COMMITMENT FEE FOR PROVIDING COMMITMENTS. In consideration of
the Lenders' agreement to commit to make the Loans available to the Borrower as
contemplated by this Agreement, the Borrower agrees to pay to the Agent from
time to time, on behalf of and for the ratable benefit of the Lenders according
to their respective Pro Rata Shares of the Aggregate Commitments, a commitment
fee in an amount equal to 0.25% multiplied by the average daily difference
between the Aggregate Commitments and (i) the sum of the aggregate outstanding
principal amount of Loans plus (ii) the Letter of Credit Undrawn Amount, due and
payable quarterly in arrears on the last Business Day of each March, June,
September and December, with the final such payment due and payable on the
Revolving Credit Maturity Date.

            (c) AGENT'S FEE. In consideration of Comerica's agreement to act as
Agent under this Agreement, the Borrower agrees to pay to the Agent an annual
agent's fee as set forth in Agent's Fee Letter.

<PAGE>   29
            (d) LETTERS OF CREDIT FEES AND COMMISSIONS.

                  (i) As a condition to issuance of each Letter of Credit, the
Borrower shall pay to the Issuing Bank for the account of each Lender according
to its Pro Rata Share a letter of credit participation fee equal to (A) for
standby Letters of Credit, the number of days between the date of such issuance
through the expiry date of such Letter of Credit, multiplied by the face amount
of such Letter of Credit, multiplied by the Applicable Margin and divided by
360, and (B) for sight documentary Letters of Credit the face amount of such
Letter of Credit multiplied by 0.40% (0.30% allocated for the account of each
Lender according to its Pro Rata Share, and 0.10% to the Issuing Bank).

                  (ii) Standby Letter of Credit fees will be payable by the
Borrower to the Issuing Bank in arrears on the last day of each Fiscal Quarter
and on the expiry date for each standby Letter of Credit and such amounts
received by the Issuing Bank shall promptly be paid to the Agent for
distribution to the Lenders. Issuance fees for sight documentary Letters of
Credit will be paid by the Borrower upon issuance and the aggregate of such fees
received by the Issuing Bank during any Fiscal Quarter will be distributed by
the Issuing Bank to the Agent for distribution to the Lenders promptly upon the
Issuing Bank's receipt thereof.

                  (iii) The Borrower shall pay to the Issuing Bank, upon demand,
all standard charges of the Issuing Bank in connection with the issuance,
extension, renewal, modification, cancellation or negotiation of any Letter of
Credit, which amounts shall include, without limitation, an issuance fee equal
to 1/8% of the face amount of each standby Letter of Credit. No fees or
commissions paid in respect of any Letter of Credit shall be refundable.

        2.9 CALCULATION OF INTEREST AND FEES. Interest on the Loans shall be
computed on the basis of a 360-day year and the actual number of days elapsed.
All fees payable hereunder shall be computed on the basis of a 360-day year and
actual days elapsed. In computing interest on any Loan, the date of the making
of such Loan shall be included and the date of payment shall be excluded;
provided, however, that if any Loan is repaid on the same day on which it is
made, such day shall be included in computing interest on such Loan. Each change
in the interest rate of the Base Rate Loans based on changes in the Base Rate
and each change in the interest rate of LIBOR Loans based on changes in the
Eurodollar Reserve Percentage shall be effective on the effective date of such
change and to the extent of such change. The Agent shall give the Borrower
prompt notice of any such change in the Base Rate or Eurodollar Reserve
Percentage; provided, however, that any failure by the Agent to provide the
Borrower with notice hereunder shall not affect the Lenders' right to make
changes in the interest rate of the Base Rate Loans based on changes in the Base
Rate or changes in the interest rate of LIBOR Loans based on changes in the
Eurodollar Reserve Percentage.

        2.10 PAYMENTS. All repayments or prepayments of principal and all
payments of interest, fees, costs, expenses and other sums chargeable to the
Borrower under this Agreement, the Notes or any of the other Loan Documents
shall be in lawful money of the United States of America in immediately
available funds and delivered to the Agent, on behalf and for the benefit


                                       28


<PAGE>   30
of the Lenders, not later than 10:00 a.m., San Jose, California time, on the
date due at the Agent's Payment Office.

        2.11 PAYMENT ON NON-BUSINESS DAYS. Whenever any payment to be made under
this Agreement, the Notes or any of the other Loan Documents shall be stated to
be due on a day which is not a Business Day, such payment shall be made on the
next succeeding Business Day and such extension of time shall in such case be
included in the computation of the payment of interest thereon.

        2.12 APPLICATION OF PAYMENTS. Except as otherwise expressly provided in
this Agreement or in any other Loan Document, all payments, when received by the
Lenders or the Agent, on behalf of Lenders, shall be applied in the following
order: (a) then due and payable fees, costs and expenses; (b) then due and
payable interest payments; and (c) then due and payable principal payments and
optional prepayments. In addition, each Lender is authorized to, and at its sole
option may, for the benefit of the Lenders and the Agent, make advances on
behalf of the Borrower for payment of any and all fees, expenses, charges,
costs, principal and interest incurred hereunder or under the other Loan
Documents. To the extent permitted by law, all amounts advanced by any Lender
hereunder or under other provisions of the Loan Documents shall accrue interest
thereon at the Base Rate.

        2.13 DISTRIBUTION OF PAYMENTS. The Agent shall immediately distribute to
each Lender, at such address as each Lender shall designate, such Lender's
interest in all repayments and prepayments of principal and all payments of
interest, loan fees, commitment fees and other fees, expenses and costs received
by the Agent on the same day and in the same type of funds as payment was
received. In the event the Agent does not distribute such payments on the same
day received, such payment shall accrue interest at the Federal Funds Rate,
which shall be payable by the Agent. The Agent shall indemnify and hold the
Borrower harmless from any claim for interest by any Lender under this SECTION
2.13.

        2.14 AGENT'S RIGHT TO ASSUME FUNDS AVAILABLE FOR LOANS. Unless the Agent
shall have been notified by any Lender no later than the Business Day prior to
the respective Funding Date of any Loan that such Lender does not intend to make
available to the Agent immediately available funds equal to such Lender's Pro
Rata Share of the total principal amount of such Loan, the Agent may assume that
such Lender has advanced funds in the amount of such Loan to the Agent on the
applicable Funding Date and the Agent may, in reliance upon such assumption,
make available to the Borrower corresponding funds. The Agent agrees to give
prompt notice to the Borrower in the event it advances funds on behalf of a
Lender under this SECTION 2.14; provided, that failure to give such notice shall
in no way limit, restrict or otherwise affect the Borrower's obligations or the
Agent's or any Lender's rights or remedies under this Agreement and the other
Loan Documents. If the Agent has made funds available to the Borrower based on
such assumption and such Loan is not in fact made available to the Agent by such
Lender, the Agent shall be entitled to recover the corresponding amount of such
Loan on demand from such Lender. If such Lender does not promptly pay such
corresponding amount upon the Agent's demand, the Agent shall notify the
Borrower and the Borrower shall repay such Loan to the Agent. The Agent also
shall be entitled to recover from such Lender interest on such Loan in


                                       29


<PAGE>   31
respect of each day from the date such Loan was made by the Agent to the
Borrower to the date such corresponding amount is recovered by the Agent at the
Federal Funds Rate, and the Agent shall indemnify and hold harmless the Borrower
from any claim for such interest.

        2.15 AGENT'S RIGHT TO ASSUME PAYMENTS WILL BE MADE BY THE BORROWER.
Unless the Agent shall have been notified by the Borrower prior to the date on
which any payment to be made by the Borrower hereunder is due that the Borrower
does not intend to remit such payment, the Agent may, in its discretion, assume
that the Borrower has remitted such payment when so due and the Agent may, in
its discretion and in reliance upon such assumption, make available to each
Lender on such payment date an amount equal to such Lender's Pro Rata Share of
such assumed payment. If the Borrower has not in fact remitted such payment to
the Agent, each Lender shall forthwith on demand repay to the Agent the amount
of such assumed payment made available to such Lender, together with interest
thereon in respect of each date from and including the date such amount was made
available by the Agent to such Lender to the date such amount is repaid to the
Agent at the Federal Funds Rate.

SECTION 3. TAXES, YIELD PROTECTION AND ILLEGALITY.

        3.1 TAXES.

            (a) Subject to SECTION 3.1(H) of this Agreement, any and all
payments by the Borrower to the Lenders or the Agent under this Agreement shall
be made free and clear of, and without deduction or withholding for, any and all
present or future taxes, fees, duties, levies, imposts, non-income tax
deductions, non-income tax charges or non-income tax withholdings, whatsoever
imposed by any Governmental Authority, excluding, in the case of each Lender and
the Agent, such taxes as are imposed on or measured by the net income of any
Lender or the Agent by any jurisdiction under the laws of which such Lender or
the Agent, as the case may be, is organized or maintains a Lending Office or any
political subdivision thereof (all such non- excluded taxes, levies, imposts,
deductions, charges, withholdings and liabilities being hereinafter referred to
as "Taxes").

            (b) In addition, the Borrower shall pay any present or future stamp
or documentary taxes or any other excise or property taxes, charges or similar
levies which arise from any payment made hereunder or from the execution,
delivery or registration of, or otherwise with respect to, this Agreement or any
other Loan Documents (hereinafter referred to as "Other Taxes").

            (c) Subject to SECTION 3.1(A) and 3.1(H) of this Agreement, if any
Taxes or Other Taxes are directly asserted or imposed against any Lender or the
Agent, the Borrower shall indemnify and hold harmless such Lender and the Agent
for the full amount of the Taxes or Other Taxes (including any Taxes or Other
Taxes asserted or imposed by any jurisdiction on amounts payable under this
SECTION 3.1) paid by such Lender or the Agent and any liability (including
penalties, interest, additions to tax and expenses) arising therefrom or with
respect thereto, whether or not such Taxes or Other Taxes were correctly or
legally asserted or imposed. Payment under this indemnification shall be made
within thirty (30) days from the date Lender


                                       30


<PAGE>   32
or Agent makes written demand therefor (provided that the Borrower shall have
the right to contest in good faith any such Taxes or Other Taxes through
appropriate proceedings). Any Lender in its discretion also may, but shall not
be obligated to, pay such Taxes or Other Taxes and the Borrower will promptly
pay, within fifteen (15) days after written demand therefor by any Lender or
Agent, such additional amounts (including any penalties, interest or expenses)
as is necessary in order that the net amount received by such Lender after the
payment of such Taxes or Other Taxes (including any Taxes on such additional
amount) shall equal the amount such Lender would have received had not such
Taxes or Other Taxes been asserted or imposed.

            (d) If the Borrower shall be required by law to deduct or withhold
any Taxes or Other Taxes from or in respect of any sum payable hereunder to any
Lender or the Agent, then, subject to SECTION 3.1(H) of this Agreement:

                (i) the sum payable shall be increased as necessary so that
            after making all required deductions (including deductions
            applicable to additional sums payable under this SECTION 3.1) such
            Lender or the Agent, as the case may be, receives an amount equal to
            the sum it would have received had no such deduction or withholding
            been made;

                (ii) The Borrower shall make such deduction or withholding; and

                (iii) The Borrower shall pay the full amount deducted to the
            relevant taxation authority or other authority in accordance with
            applicable law.

            (e) Within thirty (30) days after the date of any payment by the
Borrower of Taxes or Other Taxes, the Borrower, upon the Agent's request, shall
furnish to the Agent the original or a certified copy of a receipt evidencing
payment thereof, or other evidence of payment satisfactory to the Agent.

            (f) If the Borrower fails to pay any Taxes or Other Taxes when due
to the appropriate taxing authority or fails to furnish to the Agent the
required receipts or other required documentary evidence, the Borrower shall
indemnify the Agent and the Lenders for any incremental Taxes or Other Taxes,
interest or penalties that may become payable by the Agent and any such Lenders
as a result of any such failure.

            (g) Each of the Agent and any Lender which is a foreign Person
(i.e., a Person other than a United States Person for United States Federal
income tax purposes) agrees that:

                (i) in the case of any Lender which is a "bank" within the
            meaning of Section 881(c)(3)(A) of the Code,

                    (A) it shall, no later than the Closing Date (or, in the
            case of a Lender which becomes a party hereto pursuant to SECTION
            11.2 of this Agreement after the Closing Date, the date upon which
            such Lender becomes a party hereto) deliver to the


                                       31


<PAGE>   33
            Borrower through the Agent two (2) accurate and complete signed
            originals of IRS Form 4224 or any successor thereto ("Form 4224"),
            or two (2) accurate and complete signed originals of IRS Form 1001
            or any successor thereto ("Form 1001"), as appropriate, in each case
            indicating that such Lender is on the date of delivery thereof
            entitled to receive payments of principal, interest and fees under
            this Agreement free from withholding of United States Federal income
            tax;

                    (B) if at any time the Agent or such Lender makes any
            changes necessitating a new Form 4224 or Form 1001, it shall within
            thirty (30) days after such change becomes effective deliver to the
            Borrower through the Agent in replacement for, or in addition to,
            the forms previously delivered by it hereunder, two (2) accurate and
            complete signed originals of Form 4224; or two (2) accurate and
            complete signed originals of Form 1001, as appropriate, in each case
            indicating that such Lender is on the date of delivery thereof
            entitled to receive payments of principal, interest and fees under
            this Agreement free from withholding of United States Federal income
            tax;

                (ii) in the case of any Lender other than a Lender described in
            clause (i) above,

                    (A) it shall, no later than the Closing Date (or, in the
            case of a Lender which becomes a party hereto pursuant to SECTION
            11.2 of this Agreement after the Closing Date, the date upon which
            Lender becomes a party hereto) deliver to the Borrower through the
            Agent two (2) accurate and complete signed originals of a
            certificate substantially in the form of EXHIBIT F hereto (any such
            certificate, a "Non- Bank Lender Tax Certificate") and two (2)
            accurate and complete signed originals of IRS Form W-8 or any
            successor thereto ("Form W-8") certifying to such Lender's legal
            entitlement (assuming compliance by the Borrower with the terms of
            this Agreement) to an exemption whereby such Lender is on the date
            of delivery thereof entitled to receive payments of principal,
            interest and fees under this Agreement free from withholding of
            United States Federal income tax;

                    (B) if at any time the Agent or such Lender makes any
            changes necessitating a new Form W-8, it shall within thirty (30)
            days after such change becomes effective deliver to the Borrower
            through the Agent in replacement for, or in addition to, the forms
            previously delivered by it hereunder, two (2) accurate and complete
            signed originals of Form W-8 certifying to such Lender's legal
            entitlement (assuming compliance by the Borrower with the terms of
            this Agreement) to an exemption whereby such Lender is on the date
            of delivery thereof entitled to receive payments of principal,
            interest and fees under this Agreement free from withholding of
            United States Federal income tax;

                (iii) it shall, before or within thirty (30) days after the
            occurrence of any event (including the passing of time but excluding
            any event mentioned in (i) or (ii), above) requiring a change in or
            renewal of the most recent Form 4224, Form 1001 or Form W-8
            previously delivered by such Lender, deliver to the Borrower through
            the



                                       32


<PAGE>   34
            Agent two (2) accurate and complete original signed copies of Form
            4224, Form 1001 or Form W-8 in replacement for the forms previously
            delivered by such Lender; and

                (iv) it shall, promptly upon any Lender's or the Agent's
            reasonable request to that effect, deliver to such Lender or the
            Agent (as the case may be) such other forms or similar documentation
            as may be required from time to time by any applicable law, treaty,
            rule or regulation in order to establish such Lender's tax status
            for withholding purposes.

            (h) The Borrower will not be required to pay any additional amounts
in respect of United States Federal income tax pursuant to SECTION 3.1(D) of
this Agreement to the Agent or any Lender for the account of any Lending Office
of such Lender:

                (i) if the obligation to pay such additional amounts would not
            have arisen but for a failure by such Lender to comply with its
            obligations under SECTION 3.1(G) of this Agreement in respect of
            such Lending Office;

                (ii) if such Lender shall have delivered to the Borrower a Form
            4224, Form 1001 or Form W-8 in respect of such Lending Office
            pursuant to SECTION 3.1(G) of this Agreement, and such Lender shall
            not at any time be entitled to exemption from deduction or
            withholding of United States Federal income tax in respect of
            payments by the Borrower hereunder for the account of such Lending
            Office for any reason other than a change in United States law or
            regulations or in the official interpretation of such law or
            regulations by any Governmental Authority charged with the
            interpretation or administration thereof (whether or not having the
            force of law) after the date of delivery of such form.

            (i) If, at any time, the Borrower requests any Lender to deliver any
forms or other documentation in addition to those required pursuant to SECTION
3.1(G)(IV) of this Agreement, then the Borrower shall, on demand of such Lender
through the Agent, reimburse such Lender for any costs and expenses (including
Attorney Costs) reasonably incurred by such Lender in the preparation or
delivery of such forms or other documentation.

            (j) If the Borrower is required to pay additional amounts to any
Lender or the Agent pursuant to SECTION 3.1(D) of this Agreement, then such
Lender shall use its reasonable best efforts (consistent with legal and
regulatory restrictions) to change the jurisdiction of its Lending Office so as
to eliminate any such additional payment by such Lender which may thereafter
accrue if such change in the judgment of such Lender is not otherwise
disadvantageous to such Lender.


                                       33


<PAGE>   35
        3.2 ILLEGALITY.

            (a) If any Lender shall determine that the introduction of any
Requirement of Law, or any change in any Requirement of Law or in the
interpretation or administration thereof, has made it unlawful, or that any
central bank or other Governmental Authority has asserted that it is unlawful,
for any Lender or its Lending Office to make LIBOR Loans, then, on notice
thereof by such Lender to the Borrower through the Agent, the obligation of such
Lender to make LIBOR Loans shall be suspended until such Lender shall have
notified the Agent and the Borrower that the circumstances giving rise to such
determination no longer exists.

            (b) If a Lender shall determine that it is unlawful to maintain any
LIBOR Loan, the Borrower shall prepay in full all LIBOR Loans of that Lender
then outstanding, together with interest accrued thereon, either on the last day
of the Interest Period thereof if such Lender may lawfully continue to maintain
such LIBOR Loans to such day, or immediately, if such Lender may not lawfully
continue to maintain such LIBOR Loans, together with any amounts required to be
paid in connection therewith pursuant to SECTION 3.5 of this Agreement.

            (c) If the Borrower is required to prepay any LIBOR Loan immediately
as provided in SECTION 3.2(B) of this Agreement, then, on the date such
prepayment is required, unless such prepayment is actually made with funds from
another source, the Borrower shall be deemed to have borrowed from the affected
Lender the amount of such prepayment as a Base Rate Loan.

            (d) Before giving any notice to the Agent pursuant to this SECTION
3.2, the affected Lender shall designate a different Lending Office with respect
to its LIBOR Loans if such designation will avoid the need for giving such
notice or making such demand and will not, in the judgment of such Lender, be
illegal or otherwise disadvantageous to such Lender.

        3.3 INCREASED COSTS. If any Lender shall determine that, due to either
(a) the introduction of or any change (other than any change by way of
imposition of or increase in the Eurodollar Reserve Percentage included in the
calculation of the LIBOR) in or in the interpretation of any Requirement of Law
or (b) the compliance with any guideline or request from any central bank or
other Governmental Authority (whether or not having the force of law), there
shall be any increase in the cost to such Lender of agreeing to make or making,
funding or maintaining any LIBOR Loans, then the Borrower shall be liable for,
and shall from time to time, upon demand therefor by such Lender, pay to such
Lender such additional amounts as are sufficient to compensate such Lender for
such increased costs. Each Lender will promptly notify the Borrower and the
Agent of any event of which it has knowledge occurring after the date hereof,
which will entitle such Lender to compensation pursuant to this SECTION 3.3.

        3.4 INABILITY TO DETERMINE RATES. If the Agent shall have determined
that for any reason adequate and reasonable means do not exist for ascertaining
the LIBOR for any requested Interest Period with respect to a proposed LIBOR
Loan or that the LIBOR applicable for any requested Interest Period with respect
to a proposed LIBOR Loan does not adequately and fairly reflect the cost to the
Lenders of funding such Loan, the Agent will forthwith give notice of such


                                       34


<PAGE>   36
determination to the Borrower and each Lender. Thereafter, the obligation of the
Lenders to make or maintain LIBOR Loans, as the case may be, hereunder shall be
suspended until the Agent, upon the instruction of the Requisite Lenders,
revokes such notice in writing. Upon receipt of such notice, the Borrower may
revoke any Borrowing Notice or Conversion/Continuation Notice then submitted by
it. If the Borrower does not revoke such notice, the Lenders shall make, convert
or continue the Loans, as proposed by the Borrower, in the amount specified in
the applicable notice submitted by the Borrower, but such Loans shall be made or
continued as or converted to Base Rate Loans instead of LIBOR Loans, as the case
may be.

        3.5 PREPAYMENT OF LIBOR LOANS. In the event that the Borrower prepays or
is required to prepay any LIBOR Loan by acceleration or otherwise or fails to
draw down or convert to a LIBOR Loan after giving notice thereof, the Borrower
agrees to reimburse each Lender for its expenses and funding losses due to such
prepayment or failure to draw. The Borrower and the Lenders hereby agree that
such expenses and funding losses shall consist of the sum of the discounted
monthly differences for each month during the applicable or requested Interest
Period, calculated as follows for each such month:

            (a) principal amount of such LIBOR Loan times (number of days
between the date of prepayment and the last day in the applicable Interest
Period divided by 360), times the applicable Interest Differential; plus

            (b) all actual out-of-pocket expenses (other than those taken into
account in the calculation of the Interest Differential) incurred by the Lenders
and the Agent (excluding allocations of any expense internal to the Lenders and
the Agent) and reasonably attributable to such payment or prepayment; provided
that no prepayment fee shall be payable (and no credit or rebate shall be
required) if the product of the foregoing formula is not a positive number.

        3.6 CAPITAL REQUIREMENTS. If any Lender shall determine that any change
after the date of this Agreement in any law, rule, regulation or guideline
adopted pursuant to or arising out of the July 1988 report of the Basle
Committee on Banking Regulations and Supervisory Practices entitled
"International Convergence of Capital Measurement and Capital Standards", or the
adoption after the date hereof of any other Requirement of Law regarding capital
adequacy, or any change after the date of this Agreement in any of the foregoing
or in the enforcement or interpretation or administration of any of the
foregoing by any Governmental Authority charged with the enforcement or
interpretation or administration thereof, or compliance by any Lender (or any
Lending Office of Lender) or compliance by such Lender's holding company with
any request or directive regarding capital adequacy (whether or not having the
force of law) of any such Governmental Authority, has the effect of reducing the
rate of return on such Lender's capital or on the capital of such Lender's
holding company, if any, as a consequence of the maintaining of any of its
Commitments or the making or maintaining of any Loan under this Agreement to a
level below that which such Lender or such Lender's holding company could have
achieved but for such adoption, change or compliance (taking into consideration
such Lender's policies and the policies of such Lender's holding company with
respect to capital adequacy) by an amount deemed to be material, then, upon
written demand by such Lender, the Borrower shall pay to such Lender, from time
to time such additional amount or amounts as will 


                                       35


<PAGE>   37
compensate such Lender or such Lender's holding company for any such reduction
suffered. Without affecting its rights under this SECTION 3.6 or any other
provision of this Agreement, such Lender agrees that if there is any increase in
any cost to or reduction in any amount receivable by such Lender with respect to
which the Borrower would be obligated to compensate such Lender pursuant to this
SECTION 3.6, such Lender shall give the Borrower thirty (30) days notice thereof
and shall use reasonable efforts to select an alternative Lending Office which
would not result in any such increase in any cost to or reduction in any amount
receivable by such Lender; provided, however, that such Lender shall not be
obligated to select an alternative Lending Office if such Lender determines that
(a) as a result of such selection such Lender would be in violation of any
Requirement of Law, or would incur additional costs or expenses, or (b) such
selection would be inadvisable for regulatory reasons.

        3.7 CERTIFICATES OF LENDERS. Any Lender claiming reimbursement or
compensation pursuant to this SECTION 3 shall deliver to the Borrower (with a
copy to the Agent) a certificate setting forth in reasonable detail the amount
payable and the basis therefor to such Lender hereunder, accompanied by any
statements, invoices, or demands in the case of jurisdictions or Governmental
Authorities asserting or imposing a Tax, Other Tax or other amounts owed, with
any confidential information, including amounts, redacted. Such certificate
shall constitute a rebuttable presumption as to the matters set forth therein.

SECTION 4. CONDITIONS PRECEDENT TO LOANS.

        4.1 FIRST LOAN. The obligation of each Lender to make the first Loan
hereunder is subject to the satisfaction of the following conditions precedent:

            (a) CORPORATE DOCUMENTS. The Lenders shall have received, in form

        The Borrower hereby warrants and represents to the Agent and each Lender
for itself and each of its Material Subsidiaries as follows and agrees that each
of said representations and warranties shall be deemed to survive until full,
complete and indefeasible payment and performance of the Obligations and shall
apply anew to each Borrowing hereunder:

Subsidiaries are corporations duly organized and validly existing in good
standing under the laws of the respective jurisdictions of incorporation and are
duly qualified and licensed as a foreign corporation and authorized to do
business in each jurisdiction where their respective ownership of Property or
conduct of business requires such qualification and where the failure to so
qualify could with reasonable likelihood result in a Material Adverse Effect,
and in each jurisdiction where the Borrower or any of its Material Subsidiaries
maintain an office (a list of all such States is set forth on SCHEDULE 5.1); the
Borrower and each of its Material Subsidiaries have the corporate power and
authority, rights and franchises to own their respective Property and assets and
to carry on their respective businesses as now conducted; the Borrower and each
of its Material Subsidiaries have the corporate power and authority to execute,

and all other instruments and documents contemplated hereby or thereby.

        5.2 LOAN DOCUMENTS AND NOTES AUTHORIZED; BINDING OBLIGATIONS. The
execution, delivery and performance of this Agreement and each of the other Loan
Documents to which it is a party and the execution, delivery and payment of the
Notes have been duly authorized by all necessary and proper action on the part
of the Borrower. The Loan Documents to which the Borrower is a party constitute
legally valid and binding obligations of the Borrower enforceable against the
Borrower in accordance with their respective terms, except as enforcement
thereof may be limited by bankruptcy, insolvency or other laws affecting the
enforcement of creditors' rights generally.

        5.3 NO CONFLICT. The execution, delivery and performance of this
Agreement and each of the other Loan Documents and the execution, delivery and
payment of the Notes will not contravene any provision of the Borrower's

Subsidiaries' charter documents; will not contravene, conflict with or violate
any applicable law or regulation, or any order, writ, judgment, injunction,
decree, determination or award of any Governmental Authority; will not violate
or result in the breach of, or constitute a default under any Contracts (as
defined in SECTION 5.7) other than as set forth on SCHEDULE 5.7. The Borrower
and each of its Material Subsidiaries are not in violation or breach of or
default under any law, rule, regulation, order, writ, judgment, injunction,
decree, determination or award or any contract, agreement, lease, license,
indenture or other instrument to which they are a party, the non-compliance
with, the violation or breach of or the default under which could with
reasonable likelihood result in a Material Adverse Effect.

        5.4 SUBSIDIARIES; CAPITAL STRUCTURE. SCHEDULE 5.4 sets forth and
identifies all Subsidiaries of the 


                                       40

from time to time existing, together with the jurisdiction of organization, the
authorized and issued Stock of each such Subsidiary, by class and number and
including the percentage of each class legally owned or to be owned by the
Borrower as of the Closing Date. SCHEDULE 5.4 further sets forth the authorized
and issued Stock of Borrower by class and number and including the holders of
such Stock and the percentage of each class legally owned or to be owned by such
holders as of the Closing Date and on a fully diluted basis. Except as set forth
in SCHEDULE 5.4, there are no options, warrants, rights to purchase or similar
rights, or plans to issue any of the foregoing, covering the Stock of the
Borrower or any of the Borrower's Material Subsidiaries.

        5.5 FINANCIAL CONDITION. The Borrower's financial statements as of June
30, 1997, a copy of which heretofore has been delivered to the Agent by the
Borrower, and all other financial statements and other data submitted in writing
by the Borrower to the Agent or any Lender in connection with the request for
credit granted by this Agreement, are true, accurate and complete in all
material respects, and said financial statements and other data fairly present
the consolidated financial condition of the Borrower as of the date thereof, and
have been prepared in accordance with GAAP, subject to year-end audit
adjustments and the absence of footnotes. There has been no material adverse
change in the business, assets, operations, prospects or financial or other
condition of the Borrower since June 30, 1997. The financial projections
delivered or to be delivered by the Borrower to the Agent or any Lender in
connection with the Loan Documents have been prepared on a basis consistent with
the historical financial statements described above, except as described
therein, and are based on the good faith estimates and assumptions of management
of the Borrower, and the Borrower has no reason to believe that such estimates
and assumptions are not reasonable.

        5.6 LITIGATION. Except as set forth on SCHEDULE 5.6, there are no
claims, actions, suits, proceedings or other litigation pending or, to the best
of the Borrower's knowledge, after Due Inquiry, threatened against the Borrower
or any of its Material Subsidiaries at law or in equity before any Governmental
Authority or, to the best of the Borrower's knowledge, after Due Inquiry, any
investigation by any Governmental Authority of the Borrower's or any of its
Material Subsidiaries' affairs, Properties or assets. Except as set forth on
SCHEDULE 5.6, neither the Borrower nor any of its Material Subsidiaries has any
Contingent Liabilities which would, if adversely determined, have a Material
Adverse Effect and which are not provided for or disclosed in the financial
statements delivered to the Agent pursuant to SECTION 5.5.

        5.7 CONSENTS AND APPROVALS. Except as set forth on SCHEDULE 5.7, no

Borrower or any such Material Subsidiary is bound (collectively, "Contracts"),
is required to be obtained by the Borrower or any such Material Subsidiary in
order to make or consummate the transactions contemplated under the Loan
Documents. Except as further set forth in SCHEDULE 5.7, all material consents
and approvals of, filings and registrations with, and other actions in respect
of, all Governmental Authorities required to be obtained by the Borrower or any

<PAGE>   43
transactions contemplated under the Loan Documents have been, or prior to the
time when required will have been, obtained, given, filed or taken and are or
will be in full force and effect.

        5.8 SOLVENCY. As of the Closing and after giving effect to the
transactions contemplated by this Agreement and the other Loan Documents,
including all of the Loans made and to be made hereunder, and thereafter, the
Borrower is Solvent and each of its Material Subsidiaries is Solvent. For
purposes of this Agreement, "Solvent" means that (a) the fair market value of
the Borrower's assets will be in excess of the amount that will be required to
be paid on or in respect of the existing debts and other liabilities (including
contingent liabilities) of the Borrower as they mature; (b) the Borrower shall
not have unreasonably small capital to carry on its business as conducted or as
proposed to be conducted; (c) the Borrower does not intend to or believe that it
will incur debts beyond its ability to pay such debts as they mature (taking

to be payable on or in respect of its obligations); (d) the Borrower does not
intend to hinder, delay or defraud either present or future creditors; and (e)
the Borrower will have received fair consideration and reasonably equivalent
value in exchange for incurring its Obligations under the Loan Documents.

        5.9 EMPLOYMENT AND LABOR AGREEMENTS. Except as set forth on SCHEDULE
5.9, there are no employment agreements covering senior management of the
Borrower or any of its Material Subsidiaries and there are no collective

agreements has been furnished to the Agent.

        5.10 AGREEMENTS WITH AFFILIATES AND OTHER AGREEMENTS. Except as
disclosed on SCHEDULE 5.10, neither the Borrower nor any of its Material
Subsidiaries has entered into and, as of the Closing does not contemplate
entering into, any material agreement or contract with any Affiliate of the
Borrower other than the employment agreements disclosed on SCHEDULE 5.9. Neither
the Borrower nor any of its Material Subsidiaries is a party to or is bound by
any Contract or is subject to any restriction under its respective charter or
formation documents, which has, or is likely in the future to have, a Material
Adverse Effect.

        5.11 ERISA. All Employee Benefit Plans of the Borrower are listed on
SCHEDULE 5.11. All Pension Plans of the Borrower, including terminated Pension
Plans, that are intended to be qualified under Section 401(a) of the Code have
been determined by the IRS to be qualified. All Pension Plans of the Borrower
existing as of the date hereof continue to be so qualified. No "reportable
event" (as defined in Section 4043 of ERISA) has occurred and is continuing with
respect to any Pension Plan of the Borrower for which the thirty-day notice
requirement may not be waived other than those of which the appropriate
Governmental Authority has been notified. All Employee Benefit Plans of the
Borrower have been operated in all material respects in accordance with their
terms and applicable law, including ERISA, and no "prohibited transaction" (as
defined in ERISA and the Code) that would result in any material liability to
the Borrower or any of its Subsidiaries has occurred with respect to any such
Employee Benefit Plan.

        5.12 LABOR MATTERS. There are no strikes or other labor disputes against
the Borrower 


                                       42


<PAGE>   44
or any of its Material Subsidiaries or, to the best of the Borrower's knowledge
threatened against the Borrower or any of its Material Subsidiaries, which would
have a Material Adverse Effect. Hours worked by and payment made to employees of
the Borrower or, to the best of the Borrower's knowledge, after Due Inquiry, or
any of Borrower's Material Subsidiaries have not been in violation of the Fair
Labor Standards Act or any other applicable law dealing with such matters which
could with reasonable likelihood result in a Material Adverse Effect. All
payments due from the Borrower on account of employee health and welfare
insurance which could with reasonable likelihood result in a Material Adverse
Effect if not paid have been paid or, if not due, accrued as a liability on the
books of the Borrower.

        5.13 MARGIN REGULATIONS. The Borrower does not own any "margin
security," as that term is defined in Regulations G and U of the Federal Reserve
Board, and the proceeds of the Loans under this Agreement will be used only for
the purposes contemplated hereunder. None of the Loans will be used, directly or
indirectly, for the purpose of purchasing or carrying any margin security, for
the purpose of reducing or retiring any indebtedness which was originally
incurred to purchase or carry any margin security or for any other purpose which
might cause any of the Loans under this Agreement to be considered a "purpose
credit" within the meaning of Regulations G, T, U and X. The Borrower will not
take or permit any agent acting on its behalf to take any action which might
cause this Agreement or any document or instrument delivered pursuant hereto to
violate any regulation of the Federal Reserve Board.

        5.14 TAXES. All material federal, state, local and foreign tax returns,
reports and statements required to be filed by the Borrower and, to the best of
the Borrower's knowledge, after Due Inquiry, by any of the Borrower's Material
Subsidiaries have been filed with the appropriate Governmental Authorities and
all Charges and other impositions shown thereon to be due and payable by the
Borrower or such Material Subsidiary have been paid prior to the date on which
any fine, penalty, interest or late charge may be added thereto for nonpayment
thereof, or any such fine, penalty, interest, late charge or loss has been paid,
or the Borrower or such Material Subsidiary is contesting its liability
therefore in good faith and has fully reserved all such amounts in the financial
statements provided to the Agent pursuant to SECTION 6.1. The Borrower and each
of its Material Subsidiaries has paid when due and payable all material Charges
upon the books of the Borrower or such Material Subsidiary except as permitted
pursuant to SECTION 6.4. Proper and accurate amounts have been withheld by the
Borrower and each of its Material Subsidiaries from its employees for all
periods in full and complete compliance with the tax, social security and
unemployment withholding provisions of applicable federal, state, local and
foreign law and such withholdings have been timely paid to the respective
Governmental Authorities. The Borrower and each of its Material Subsidiaries has
not executed or filed with the IRS or any other Governmental Authority any
agreement or other document extending, or having the effect of extending, the
period for assessment or collection of any Charges.

        5.15 TRADEMARKS, PATENTS, COPYRIGHTS AND LICENSES. The Borrower and each
of its Material Subsidiaries possess and either own or have the right to use to
the extent required all necessary trademarks, trade names, copyrights, patents,

respective businesses as now operated, and each such trademark,

applicable federal, state or foreign application and registration numbers, on

respective business without infringement or, to the best of the Borrower's
knowledge, after Due Inquiry, claim of infringement of any trademark, trade
name, trade secret, service mark, patent, copyright, license or other
intellectual property Right of Others, except where such infringement or claim
of infringement could not with reasonable likelihood result in a Material
Adverse Effect. There is no infringement or, to the best of the Borrower's
knowledge, after Due Inquiry, claim of infringement by others of any material
trademark, trade name, trade secret, service mark, patent, copyright, license or
other intellectual property right of the Borrower or any of its Material
Subsidiaries.

        5.16 NO BROKERS. No broker or finder acting on behalf of the Borrower
brought about the obtaining, making or closing of this Agreement or the credit
made available by the Lenders to the Borrower pursuant to this Agreement, and
neither the Borrower nor any Affiliate of the Borrower has any obligation to pay
any Person in respect of any finder's or brokerage fees in connection with the
credit facilities contemplated by this Agreement.

        5.17 FULL DISCLOSURE. As of the Closing Date, no information contained
in this Agreement, the other Loan Documents or, to the best of the Borrower's
knowledge, any other documents or written materials furnished by or on behalf of
the Borrower to the Agent or any Lender pursuant to the terms of this Agreement
or any of the other Loan Documents contains any untrue or inaccurate statement
of a material fact or omits to state a material fact necessary to make the
statement contained herein or therein not misleading in light of the
circumstances under which made.

        5.18 OTHER REGULATIONS. The Borrower is not: (a) a "public utility
company" or a "holding company," or an "affiliate" or a "subsidiary company" of
a "holding company," or an "affiliate" of such a "subsidiary company," as such
terms are defined in the Public Utility Holding Company Act or (b) an
"investment company," or an "affiliated person" of, or a "promoter" or
"principal underwriter" for, an "investment company," as such terms are defined
in the Investment Company Act. The making of the Loans hereunder and the
application of the proceeds and repayment thereof by the Borrower and the
performance of the transactions contemplated by this Agreement and the other
Loan Documents will not violate any provision of the Investment Company Act, or
any rule, regulation or order issued by the SEC thereunder.

        5.19 HAZARDOUS MATERIALS. Neither the Borrower nor any of its Material
Subsidiaries has used Hazardous Materials (as defined hereinafter) on or
affecting any premises at which the Borrower or any of its Material Subsidiaries
has a place of business (collectively and singly the "premises") in any manner
which violates federal, state or local laws, ordinances, statutes, rules,
regulations or judgments governing the use, storage, treatment, handling,
manufacture, transportation, or disposal of Hazardous Materials ("Environmental
Laws"). The Borrower has never received any notice ("Environmental Complaint")
of any violations of Environmental Laws (and, within five (5) days of receipt of

the event that such information is not otherwise delivered by the Borrower to
the Agent or the Lenders pursuant to this Agreement), so long as there are

matter hereafter arising which, if existing or occurring at the date of this
Agreement, would have been required to be set forth or described by the Borrower
in this Agreement or any of the other Loan Documents (including all Schedules

connection with one or more Acquisitions on or after July 1, 1997 by the

previously incurred costs associated with in-process research and development
must be written off, the minimum required Consolidated Effective Tangible Net
Worth shall be reduced by the amount of such write-offs to the extent that the
aggregate amount of all such write-offs in connection with such Acquisitions
does not exceed $50,000,000.

any other document or agreement executed by the Borrower or its Subsidiaries in
connection therewith and the same has not been cured to Requisite Lenders'
satisfaction within thirty (30) calendar days after the Borrower shall become
aware thereof, whether by written notice from the Agent or any Lender or
otherwise or should reasonably have become aware thereof; provided, however,
that if the same is susceptible of cure but, due to the nature thereof, cannot
be cured within said thirty (30) day period, such cure period shall be extended
for a reasonable period of time not exceeding an additional sixty (60) days so
long as the Borrower has commenced said cure within such thirty (30) day period
and is at all times thereafter diligently completing the cure thereof; or

            (g) INSOLVENCY; VOLUNTARY PROCEEDINGS. The Borrower or any of its

<PAGE>   59
            (k) INVALIDITY OF LOAN DOCUMENTS. Any material provision of the Loan
Documents, for any reason other than the satisfaction in full of the Obligations
thereunder, shall cease to be, or shall be asserted by the Borrower not to be, a
legal, valid and binding obligation of the Borrower or its applicable
Subsidiaries, enforceable in accordance with its terms, and such occurrence has
not been cured to Requisite Lenders' satisfaction within five (5) Business Days
after the Borrower shall have received notice of such failure from the Agent or
any Lender or within thirty (30) days of when the Borrower shall have become
aware thereof (whichever period is less); or

            (l) CHANGE OF CONTROL. There shall occur any Change of Control; or

            (m) SUSPENSION OF BUSINESS OPERATIONS. If the Borrower or any of its
Subsidiaries shall, other than in the ordinary course of business (as determined
by past practices), suspend all or any part of its operations material to the
conduct of the business of the Borrower or such Subsidiary for a period of more
than 60 consecutive days, which suspension in the good faith judgment of the
Agent could reasonably be expected to have a Material Adverse Effect; or

            (n) MATERIAL ADVERSE CHANGE. There shall have been a change in the
assets, liabilities, financial condition, operations or affairs of the Borrower
or any of its Subsidiaries, other than changes in the ordinary course of
business, which in the reasonable determination of Requisite Lenders has, either
individually or in the aggregate, a Material Adverse Effect.

        9.2 WAIVER OF DEFAULT. Any Event of Default may be waived only with the
written consent of Requisite Lenders; except that any Event of Default under any
of SECTIONS 9.1(A), 9.1(B), 9.1(G) and 9.1(H) of this Agreement may only be
waived with the written consent of all Lenders. Any Event of Default so waived
shall be deemed to have been cured and not to be continuing; but no such waiver
shall be deemed a continuing waiver or shall extend to or affect any subsequent
like default or impair any rights arising therefrom.

        9.3 REMEDIES. Upon the occurrence and continuance of any Event of
Default or Potential Event of Default, the Lenders shall have no further
obligation to advance money or extend credit to or for the benefit of the
Borrower. In addition, upon the occurrence and during the continuance of an
Event of Default, the Lenders or the Agent, on behalf of the Lenders, may, at
the option of Requisite Lenders, do any one or more of the following, all of
which are hereby authorized by the Borrower:

            (a) Declare all or any of the Obligations of the Borrower under this
Agreement, the Notes, the other Loan Documents and any other instrument executed
by the Borrower pursuant to the Loan Documents to be immediately due and
payable, and upon such declaration such Obligations so declared due and payable
shall immediately become due and payable; provided that if such Event of Default
is under part (g) or (h) of SECTION 9.1 of this Agreement, then all of the
Obligations shall become immediately due and payable forthwith without the
requirement of any notice or other action by the Lenders or the Agent;


                                       58


<PAGE>   60
            (b) Terminate this Agreement as to any future liability or
obligation of the Lenders; provided that if such Event of Default is under part
(g) or (h) of SECTION 9.1 of this Agreement, then all future liability and
obligations of the Lenders shall immediately terminate without the request or
notice or other action by the Lenders or the Agent.

            (c) To the extent permitted by laws applicable to the making of
dividends or distributions to equity holders, but without regard to any negative
effect on the Borrower's tax status, require the Borrower to cause each of its
Subsidiaries to dividend to the Borrower all cash flow;

            (d) Exercise in addition to all other rights and remedies granted
hereunder, any and all rights and remedies granted under the Loan Documents or
otherwise available at law or in equity; and

            (e) Demand that the Borrower (i) deposit cash with the Agent in an
amount equal to the amount of any Letter of Credit Undrawn Amount remaining
undrawn, as collateral security for the repayment of any future drawings under
such Letters of Credit, and the Borrower shall forthwith deposit and pay such
amounts, and (ii) pay in advance all Letter of Credit fees and commissions
scheduled or payable over the remaining term of each Letter of Credit.

        9.4 SET-OFF.

            (a) RIGHTS OF SET-OFF. Subject to SECTION 9.4(B) below, during the
continuance of an Event of Default, any deposits or other sums credited by or
due from any Lender to the Borrower may be set off against the Obligations and
any and all other liabilities, direct or indirect, absolute or contingent, due
or to become due, now existing or hereafter arising, of the Borrower to the
Lenders.

            (b) REQUISITE LENDERS' CONSENT TO SET-OFF REQUIRED. Each Lender
agrees that it shall not, and that it shall not attempt to, exercise any right
of set-off, banker's lien or similar remedy against any of the Property of the
Borrower without the prior written consent of Agent or Requisite Lenders.

        9.5 SHARING OF PAYMENTS. If, other than as expressly provided elsewhere
herein, any Lender shall receive from the Borrower or any other source
whatsoever on account of the Loans made by it any payment (whether voluntary,
involuntary, through the exercise of any right of set-off, bankers' lien,
counterclaim, cross-action, enforcement of any claim evidenced by this Agreement
or any of the other Loan Documents or by proof thereof in any case under the
Bankruptcy Code or similar proceeding or otherwise) which is in excess of its
respective Pro Rata Share of payments on account of the Loans obtained by all
Lenders with respect to such Loans, such Lender shall forthwith (a) notify the
Agent of such fact and (b) make such dispositions and arrangements with each
other Lender with respect to such excess, either by way of distribution until
the amount of such excess has been exhausted, assignment of claims, subrogation
or otherwise, as shall result in each such Lender receiving in respect of the
amounts 


                                       59


<PAGE>   61
due such Lender, under this Agreement its ratable share of such payments;
provided, however, that if all or any part of such excess payment is thereafter
recovered from such Lender, such disposition and arrangements shall be rescinded
and the amount restored to the extent of such recovery, but without interest.

        9.6 RIGHTS AND REMEDIES CUMULATIVE. The Lenders' and the Agent's rights
and remedies under this Agreement shall be cumulative. The Lenders and the Agent
shall have all other rights and remedies not inconsistent herewith as provided
at law or in equity. No exercise by any Lender or the Agent of one right or
remedy shall be deemed an election. No delay by any Lender or the Agent shall
constitute a waiver, election or acquiescence by such party.

SECTION 10. AGENT.

        10.1 APPOINTMENT AND AUTHORIZATION. Each Lender hereby irrevocably
appoints, designates and authorizes Comerica as the Agent under this Agreement
and under each of the other Loan Documents and irrevocably authorizes the Agent
to take such action on its behalf under and subject to the provisions of this
Agreement and each other Loan Document and to exercise such powers and perform
such duties as are expressly delegated to it by the terms of this Agreement or
any other Loan Document, together with such powers as are reasonably incidental
thereto. Notwithstanding any provision to the contrary contained elsewhere in
this Agreement or in any other Loan Document, the Agent shall not have any
duties or responsibilities, except those expressly set forth herein, nor shall
the Agent have or be deemed to have any fiduciary relationship with any Lender,
and no implied covenants, functions, responsibilities, duties, obligations or
liabilities shall be read into this Agreement or any other Loan Document or
otherwise exist against the Agent.

        10.2 DELEGATION OF DUTIES. The Agent may execute any of its duties under
this Agreement or any other Loan Document by or through agents, employees or
attorneys-in-fact and shall be entitled to advice of counsel concerning all
matters pertaining to such duties. The Agent shall not be responsible for the
negligence or misconduct of any agent or attorney-in-fact that it selects with
reasonable care.

        10.3 LIABILITY OF AGENT. None of the Agent-Related Persons shall (a) be
liable for any action taken or omitted to be taken by any of them under or in
connection with this Agreement or any other Loan Document (except for its own
gross negligence or willful misconduct), or (b) be responsible in any manner to
any Lender for any recital, statement, representation or warranty made by the
Borrower or any Affiliate of the Borrower, or any officer thereof, contained in
this Agreement or in any other Loan Document, or in any certificate, report,
statement or other document referred to or provided for in, or received by the
Agent under or in connection with, this Agreement or any other Loan Document, or
for the value of any Collateral or the validity, effectiveness, genuineness,
enforceability or sufficiency of this Agreement or any other Loan Document, or
for any failure of the Borrower or any other party to any Loan Document to
perform their obligations hereunder or thereunder. No Agent-Related Person shall
be under any obligation to any Lender to ascertain or to inquire as to the
observance or performance of any of the agreements contained in, or conditions
of, this Agreement or any other Loan Document, or 


                                       60


<PAGE>   62
to inspect the Properties, books or records of the Borrower or any of its
Affiliates.

        10.4 RELIANCE BY AGENT.

            (a) The Agent shall be entitled to rely, and shall be fully
protected in relying, upon any writing, resolution, notice, consent,
certificate, affidavit, letter, telegram, facsimile, telex or telephone message,
statement or other document or conversation believed by it to be genuine and
correct and to have been signed, sent or made by the proper Person or Persons,
and upon advice and statements of legal counsel directed to the Agent (including
counsel to the Borrower), independent accountants and other experts selected by
the Agent. The Agent shall be fully justified in failing or refusing to take any
action under this Agreement or any other Loan Document unless it shall first
receive such advice or concurrence of Requisite Lenders or all the Lenders where
so required as it deems appropriate and, if it so requests, it shall first be
indemnified to its satisfaction by the Lenders against any and all liability and
expense which may be incurred by it by reason of taking or continuing to take
any such action. The Agent shall in all cases be fully protected in acting, or
in refraining from acting, under this Agreement or any other Loan Document in
accordance with a request or consent of the Requisite Lenders or all the Lenders
where so required and such request and any action taken or failure to act
pursuant thereto shall be binding upon all of the Lenders.

            (b) For purposes of determining compliance with the conditions
precedent specified in SECTION 4, each Lender that has executed this Agreement
or shall hereafter execute and deliver an Assignment and Acceptance in
accordance with SECTION 11.2(A) of this Agreement shall be deemed to have
consented to, approved or accepted or to be satisfied with each document or
other matter either sent by the Agent to such Lender for consent, approval,
acceptance or satisfaction, or required thereunder to be consented to or
approved by or acceptable or satisfactory to Lender, unless an officer of the
Agent responsible for the transactions contemplated by the Loan Documents shall
have received notice from such Lender prior to the initial Borrowing specifying
its objection thereto and either such objection shall not have been withdrawn by
notice to the Agent to that effect or such Lender shall not have made available
to Agent such Lender's ratable portion of such Borrowing.

        10.5 NOTICE OF DEFAULT. The Agent shall not be deemed to have knowledge
or notice of the occurrence of any Potential Event of Default or Event of
Default, except with respect to defaults in the payment of principal, interest
and fees required to be paid to the Agent on behalf and for the benefit of the
Lenders, unless the Agent shall have received written notice from a Lender or
the Borrower referring to this Agreement, describing such Potential Event of
Default or Event of Default and stating that such notice is a "notice of
default." In the event that the Agent receives such a notice, the Agent shall
give notice thereof to the Lenders. The Agent shall take such action with
respect to such Potential Event of Default or Event of Default as shall be
requested by Requisite Lenders in accordance with this SECTION 10; provided,
however, that unless and until the Agent shall have received any such request,
the Agent may (but shall not be obligated to) take such action, or refrain from
taking such action, with respect to such Potential Event of Default or Event of
Default as it shall deem in the best interest of the Lenders.


                                       61


<PAGE>   63
        10.6 NON-RELIANCE. Each Lender expressly acknowledges that none of the
Agent-Related Persons has made any representation or warranty to it and that no
act by the Agent hereafter taken, including any review of the affairs of the
Borrower, shall be deemed to constitute any representation or warranty by the
Agent to any Lender. Each Lender confirms to the Agent that it has not relied,
and will not hereafter rely, on the Agent to check or inquire on such Lender's
behalf into the adequacy, accuracy or completeness of any information provided
by the Borrower or any other Person under or in connection with the Loan
Documents or the transactions herein contemplated (whether or not the
information has been or is hereafter distributed to such Lender by the Agent).
Each Lender represents to the Agent that it has, independently and without
reliance upon the Agent and based on such documents and information as it has
deemed appropriate, made its own appraisal of and investigation into the
business, prospects, operations, property, financial and other condition and
creditworthiness of the Borrower, and all applicable bank regulatory laws
relating to the transactions contemplated thereby, and made its own decision to
enter into this Agreement and extend credit to the Borrower under and pursuant
to this Agreement. Each Lender also represents that it will, independently and
without reliance upon the Agent and based on such documents and information as
it shall deem appropriate at the time, continue to make its own credit analysis,
appraisals and decisions in taking or not taking action under this Agreement and
the other Loan Documents, and to make such investigations as it deems necessary
to inform itself as to the business, prospects, operations, property, financial
and other condition and creditworthiness of the Borrower. Except for notices,
reports and other documents expressly herein required to be furnished to the
Lenders by the Agent, the Agent shall not have any duty or responsibility to
provide any Lender with any credit or other information concerning the business,
prospects, operations, property, financial and other condition or
creditworthiness of the Borrower which may come into the possession of any
Agent-Related Persons. The Agent shall not be responsible to any Lender for the
execution, effectiveness, genuineness, validity, enforceability, collectibility
or sufficiency of this Agreement or any other Loan Document or for any
representations or warranties, recitals or statements made herein or therein or
made in any written or oral statements, or in any financial or other statements,
instruments, reports or certificates or any other documents furnished or made by
the Agent to the Lenders or by or on behalf of the Borrower to the Agent or any
Lender in connection with the Loan Documents and the transactions contemplated
thereby or for the financial condition or business affairs of the Borrower or
any other Person liable for the payment of any Obligations, nor shall the Agent
be required to ascertain or inquire as to the performance or observance of any
of the terms, conditions, provisions, covenants or agreements contained in any
of the Loan Documents or as to the use of the proceeds of the Loans or as to the
existence or possible existence of any Event of Default or Potential Event of
Default.

        10.7 INDEMNIFICATION. Whether or not the transactions contemplated
hereby shall be consummated, the Lenders shall indemnify upon demand all
Agent-Related Persons (to the extent not reimbursed by or on behalf of the
Borrower and without limiting the obligation of the Borrower to do so), ratably
from and against any and all liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses and disbursements of any
kind whatsoever which may at any time (including at any time following the
repayment of the Loans and the termination or resignation of the related Agent)
be imposed on, incurred by or asserted against 


                                       62


<PAGE>   64
any such Person in any way relating to or arising out of this Agreement or any
document contemplated by or referred to herein or therein or the transactions
contemplated hereby or thereby or any action taken or omitted by any such Person
under or in connection with any of the foregoing; provided, however, that no
Lender shall be liable for the payment to Agent-Related Persons of any portion
of such liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements resulting from such Person's
gross negligence or willful misconduct. Without limitation of the foregoing,
each Lender shall reimburse the Agent upon demand for its ratable share of any
costs or other out-of-pocket expenses (including Attorney Costs) incurred by the
Agent in connection with the preparation, execution, delivery, administration,
modification, amendment or enforcement (whether through negotiations, legal
proceedings or otherwise) of, or legal advice in respect of rights or
responsibilities under, this Agreement, any other Loan Document, or any document
contemplated by or referred to herein to the extent that the Agent is not
reimbursed for such expenses by or on behalf of the Borrower. Without limiting
the generality of the foregoing, if the IRS or any other Governmental Authority
of the United States of America or other jurisdiction asserts a claim that the
Agent did not properly withhold tax from amounts paid to or for the account of
any Lender (because the appropriate form was not delivered, was not properly
executed, or because such Lender failed to notify the Agent of a change in
circumstances which rendered the exemption from, or reduction of, withholding
tax ineffective, or for any other reason), such Lender shall indemnify the Agent
fully for all amounts paid, directly or indirectly, by the Agent as tax or
otherwise, including penalties and interest, and including any taxes imposed by
any jurisdiction on the amounts payable to the Agent under this SECTION 10.7,
together with all costs and expenses (including Attorney Costs). The obligation
of the Lenders in this SECTION 10.7 shall survive the payment of all
Obligations.

        10.8 AGENT IN INDIVIDUAL CAPACITY. Comerica and its Affiliates may make
loans to, issue letters of credit for the account of, accept deposits from,
acquire equity interests in and generally engage in any kind of banking, trust,
financial advisory or other business with the Borrower and its Affiliates as
though Comerica were not the Agent hereunder and without notice to or consent of
the Lenders. With respect to its Loans, Comerica shall have the same rights and
powers under this Agreement as any other Lender and may exercise the same as
though it were not the Agent, and the terms "Lender" and "Lenders" shall include
Comerica in its individual capacity.

        10.9 SUCCESSOR AGENT. The Agent may, and at the request of Requisite
Lenders shall, resign as the Agent upon thirty (30) days' notice to the Borrower
and the Lenders. If the Agent shall resign as Agent under this Agreement,
Requisite Lenders shall appoint from among the Lenders a successor agent for the
Lenders. If no successor agent is appointed prior to the effective date of the
resignation of the Agent, the Agent may appoint, after consulting with the
Lenders and the Borrower, a successor agent from among the Lenders. Upon the
acceptance of its appointment as successor agent hereunder, such successor agent
shall succeed to all the rights, powers and duties of the retiring Agent and the
term "Agent" shall mean such successor agent and the retiring Agent's
appointment, powers and duties as Agent shall be terminated. After any retiring
Agent's resignation hereunder as Agent, the provisions of this SECTION 10 shall
inure to its benefit as to any actions taken or omitted to be taken by it while
it was the Agent under this 


                                       63


<PAGE>   65
Agreement. If no successor agent has accepted appointment as Agent by the date
which is thirty (30) days following a retiring Agent's notice of resignation,
the retiring Agent's resignation shall nevertheless thereupon become effective
and the Lenders shall perform all of the duties of the Agent hereunder until
such time, if any, as Requisite Lenders appoint a successor agent as provided
for above.

        10.10 DOCUMENTATION AGENT. The Documentation Agent shall not have any
right, power, obligation, liability, responsibility or duty under this Agreement
other than those applicable to all Lenders as such. Without limiting the
foregoing, the Documentation Agent shall not be deemed to have any fiduciary
relationship with any Lender. Each Lender acknowledges that it has not relied,
and will not rely, on any of the Lenders so identified in deciding to enter into
this Agreement or in taking or not taking any action hereunder.

SECTION 11. AMENDMENTS AND WAIVERS; ASSIGNMENTS, PARTICIPATION, ETC.

        11.1 AMENDMENTS AND WAIVERS. No amendment, modification or waiver of any
provision of this Agreement or any other Loan Document, and no consent with
respect to any departure by the Borrower therefrom, shall be effective unless
the same shall be in writing and signed by Requisite Lenders and acknowledged by
the Agent, and then such waiver shall be effective only in the specific instance
and for the specific purpose for which given; provided, however, that no such
waiver, amendment, or consent shall, unless in writing and signed by all Lenders
and acknowledged by the Agent, do any of the following:

            (a) increase or extend the Commitment of any Lender (or reinstate
any Commitment terminated pursuant to SECTION 9.3 of this Agreement) or subject
any Lender to any additional obligations;

            (b) postpone or delay any date fixed for any payment of principal,
interest, fees or other amounts due to the Lenders (or any of them) hereunder or
under any Loan Document (including in respect of any Mandatory Prepayment);

            (c) reduce the principal of, or the rate of interest specified
herein on any Loan, or of any fees or other amounts payable hereunder or under
any Loan Document;

            (d) change the percentage of the Commitments or of the aggregate
unpaid principal amount of the Loans which shall be required for the Lenders or
any of them to take any action hereunder;

            (e) amend this SECTION 11.1;

and, provided further, that no amendment, modification, waiver or consent shall,
unless in writing and signed by the Agent in addition to Requisite Lenders or
all Lenders, as the case may be, affect the rights or duties of the Agent under
this Agreement or any other Loan Document.


                                       64


<PAGE>   66
        11.2 ASSIGNMENTS, PARTICIPATION, ETC.

            (a) Any Lender may, with the written consent executed by the
Borrower (at all times other than during the existence of an Event of Default in
which event the Borrower's consent shall not be required) and the Agent (and
written notice to each other Lender), which consents shall not be unreasonably
withheld or delayed, at any time assign and delegate to one or more Eligible
Assignees (provided that no written consent of the Borrower, the Issuing Bank or
the Agent shall be required in connection with any assignment and delegation by
such Lender to an Affiliate of such Lender which Affiliate is controlled by or
under common control with such Lender) (each an "Assignee") all, or any ratable
part of all, of the Loans, the Commitments and the other rights and obligations
of such Lender hereunder, in a minimum amount of the aggregate Commitments of
$10,000,000; provided, however, that the Borrower and the Agent may continue to
deal solely and directly with such Lender in connection with the interest so
assigned to an Assignee until (A) written notice of such assignment, together
with payment instructions, addresses and related information with respect to the
Assignee, shall have been given to the Borrower and the Agent by such Lender and
the Assignee; (B) such Lender and its Assignee shall have delivered to the
Borrower and the Agent an Assignment and Acceptance in the form of EXHIBIT G
("Assignment and Acceptance") together with any Note or Notes subject to such
assignment; and (C) the assignor Lender or Assignee has paid to the Agent a
processing fee of $3,000; provided that no processing fee shall be charged for
any assignment to a Lender or an Affiliate of a Lender, and further provided
that the Borrower shall not pay any fees or costs in connection with such
assignment.

            (b) From and after the date that the Agent notifies the assigning
Lender that it has received an executed Assignment and Acceptance and payment of
the above-referenced processing fee, (i) the Assignee thereunder shall be a
party hereto and, to the extent that rights and obligations hereunder have been
assigned to it pursuant to such Assignment and Acceptance, shall have the rights
and obligations of a Lender under the Loan Documents, and (ii) the assigning
Lender shall, to the extent that rights and obligations hereunder and under the
other Loan Documents have been assigned by it pursuant to such Assignment and
Acceptance, relinquish its rights and be released from its obligations under the
Loan Documents; provided, however, that the assigning Lender shall not
relinquish its rights to indemnification pursuant to SECTION 12.3 of this
Agreement, such rights to indemnification shall survive the assignment and the
assigning Lender shall retain such rights co-extensively with the other
Indemnitees.

            (c) Within five (5) Business Days after its receipt of notice by the
Agent that it has received an executed Assignment and Acceptance and payment of
the processing fee, the Borrower shall execute and deliver to the Agent new
Notes on the same terms and conditions as the original Notes evidencing such
Assignee's assigned Loans and Commitments and, if the assignor Lender has
retained a portion of its Loans and its Commitments, replacement Notes in the
principal amount of the Loans retained by the assignor Lender (such Notes to be
in exchange for, but not in payment of, the Notes held by such Lender).
Immediately upon each Assignor, Lender or its Assignee's making its processing
fee payment under the Assignment and Acceptance, this Agreement shall be deemed
to be amended to the extent, but only to the extent, necessary to reflect the
addition of the Assignee and the resulting adjustment of the Commitments 


                                       65


<PAGE>   67
arising therefrom. The Commitments allocated to each Assignee shall reduce such
Commitments of the assigning Lender pro tanto.

            (d) Any Lender may at any time sell to one or more commercial banks
or other Persons not Affiliates of the Borrower and not reasonably known after
Due Inquiry by such Lender to be an active competitor of the Borrower (a
"Participant") participating interests in any Loans, the Commitment of that
Lender and the other interests of that Lender (the "Originating Lender")
hereunder and under the other Loan Documents in a minimum amount of $10,000,000;
provided, however, that (i) the Originating Lender's obligations under this
Agreement shall remain unchanged, (ii) the Originating Lender shall remain
solely responsible for the performance of such obligations, (iii) the Borrower
and the Agent shall continue to deal solely and directly with the Originating
Lender in connection with the Originating Lender's rights and obligations under
this Agreement and the other Loan Documents, and (iv) no Lender shall transfer
or grant any participating interest under which the Participant shall have
rights to approve any amendment to, or any consent or waiver with respect to,
this Agreement or any other Loan Documents, except to the extent such amendment,
consent or waiver would require unanimous consent of Lenders as described in
clauses (A), (C) and (D) of the first proviso to SECTION 11.1 of this Agreement.
In the case of any such participation, the Participant shall be entitled to the
benefit of SECTIONS 3.1, 3.3, 3.6, 11.1 of this Agreement (but solely with
respect to those matters set forth in clauses (A), (C) and (D) thereof requiring
the consent of all Lenders), and 12.3 as though it were also a Lender hereunder,
and if amounts outstanding under this Agreement are due and unpaid, or shall
have been declared or shall have become due and payable upon the occurrence of
an Event of Default, each Participant shall be deemed to have the right of
set-off in respect of its participating interest in amounts owing under this
Agreement to the same extent as if the amount of its participating interests
were owing directly to it as a Lender under this Agreement.

            (e) Each Lender agrees to take normal and reasonable precautions and
exercise due care to maintain the confidentiality of all information identified
as "confidential" by the Borrower and provided to it by the Borrower, or by the
Agent on the Borrower's behalf, in connection with this Agreement or any other
Loan Document, and neither it nor any of its Affiliates shall use, or disclose
any such information for any purpose or in any manner other than pursuant to the
terms contemplated by this Agreement; except to the extent such information (i)
was or becomes generally available to the public other than as a result of a
disclosure by such Lender, or (ii) was or becomes available on a
non-confidential basis from a source other than the Borrower, provided that such
source is not bound by a confidentiality agreement with the Borrower known to
Lender; provided, however, that any Lender may disclose such information (A) at
the request or pursuant to any requirement of any Governmental Authority to
which such Lender is subject or in connection with an examination of such Lender
by any such authority; (B) pursuant to subpoena or other court process; (C) when
otherwise required to do so in accordance with the provisions of any applicable
Requirement of Law; and (D) to such Lender's independent auditors and other
professional advisors, provided that such auditors and professional advisors
shall be required to similarly protect the confidentiality of such information.
Notwithstanding the foregoing, the Borrower authorizes each Lender to disclose
to any Participant or Assignee (each, a "Transferee") and to any prospective
Transferee, such financial and other information in 


                                       66


<PAGE>   68
such Lender's possession concerning the Borrower which has been delivered to the
Agent or the Lenders pursuant to this Agreement or which has been delivered to
the Agent or the Lenders by the Borrower in connection with the Lenders' credit
evaluation of the Borrower prior to entering into this Agreement; provided that,
unless otherwise agreed in writing in advance by the Borrower, such Transferee
agrees in writing to such Lender and Borrower to keep such information
confidential to the same extent required of Lenders hereunder.

            (f) Notwithstanding any other provision contained in this Agreement
or any other Loan Document to the contrary, any Lender may assign all or any
portion of the Loans or Notes held by it to any Federal Reserve Bank or the
United States Treasury as collateral security pursuant to Regulation A of the
Board of Governors of the Federal Reserve System and any Operating Circular
issued by such Federal Reserve Bank, provided that any payment in respect of
such assigned Loans or Notes made by the Borrower to or for the account of the
assigning or pledging Lender in accordance with the terms of this Agreement
shall satisfy the Borrower's obligations hereunder in respect to such assigned
Loans or Notes to the extent of such payment. No such assignment shall release
the assigning Lender from its obligations hereunder.

SECTION 12. MISCELLANEOUS.

        12.1 NO WAIVER BY AGENT OR LENDERS. No failure or delay on the part of
the Agent or any Lender in the exercise of any power, right or privilege under
this Agreement, the Notes or any of the other Loan Documents shall impair such
power, right or privilege or be construed to be a waiver of any default or
acquiescence therein, nor shall any single or partial exercise of any such
power, right or privilege preclude other or further exercise thereof or of any
other right, power or privilege.

        12.2 ENTIRE AGREEMENT; CONSTRUCTION.

            (a) This Agreement, the Notes and each of the other Loan Documents
dated as of the date hereof, taken together, constitute and contain the entire
agreement among the Borrower, the Lenders and the Agent and supersede any and
all prior agreements, negotiations, correspondence, understandings and
communications among the parties, whether written or oral, respecting the
subject matter hereof.

            (b) This Agreement is the result of negotiations between and has
been reviewed by the Borrower, the Lenders executing this Agreement as of the
Closing Date and the Agent and their respective counsel; accordingly, this
Agreement shall be deemed to be the product of the parties hereto, and no
ambiguity shall be construed in favor of or against the Borrower, the Lenders or
the Agent. The Borrower, the Lenders and the Agent each severally agree that
they intend the literal words of this Agreement and the other Loan Documents and
that no parol evidence shall be necessary or appropriate to establish the
Borrower's, any Lender's or the Agent's actual intentions.

        12.3 INDEMNIFICATION. To the fullest extent permitted by law, the
Borrower agrees to protect, indemnify, defend and hold harmless the Agent, each
Lender and each of their 


                                       67


<PAGE>   69
respective directors, officers, employees and agents and any Person who controls
any of them within the meaning of the federal, state and foreign securities laws
(each an "Indemnitee" and collectively, the "Indemnitees") from and against any
liabilities, losses, obligations, damages, penalties, expenses or costs of any
kind or nature and from any suits, judgments, claims or demands (including,
without limitation, in respect of or for reasonable fees and other disbursements
of counsel for and consultants of such Indemnitees in connection with any
investigative, administrative or judicial proceeding, whether or not such
Indemnitees shall be designated a party thereto) based on any federal, state,
local or foreign law or other statutory regulation, including, without
limitation, securities, environmental and commercial law or other statutory
regulation, which arises under common law or at equitable cause or on contract
or otherwise on account of or in connection with any matter or thing or any
action or failure to act by the Indemnitees, or any of them, arising out of or
relating to the Loan Documents or any agreement or instrument contemplated by
the Loan Documents, except to the extent such liability arises from the willful
misconduct or gross negligence of any of the Indemnitees (collectively, the
"Indemnified Matters"). Upon receiving knowledge of any suit, claim, demand or
any other matter asserted by any Person that the Agent or any Lender believes is
covered by this indemnity, the Agent or such Lender shall give the Borrower
notice of the matter and an opportunity to defend it, at the Borrower's sole
cost and expense, with legal counsel reasonably satisfactory to the Agent and
the Lenders. The Agent or the Lenders may also require the Borrower to defend
the matter. The obligations of the Borrower under this SECTION 12.3 shall
survive the payment and performance of the Obligations and the termination of
this Agreement. To the extent that the undertaking to indemnify, pay and hold
harmless set forth in this SECTION 12.3 may be unenforceable because it is
violative of any law or public policy, the Borrower shall contribute the maximum
portion which it is permitted to pay and satisfy under applicable law to the
payment and satisfaction of all Indemnified Matters incurred by the Indemnitees.

        12.4 NOTICES.

            (a) All notices, requests and other communications provided for
hereunder shall be in writing (including, unless the context expressly otherwise
provides, by facsimile transmission, provided that any matter transmitted by the
Borrower by facsimile (i) shall be immediately confirmed by a telephone call to
the recipient at the number specified on the applicable signature page hereof,
and (ii) shall be followed promptly by a hard copy original thereof) and mailed,
faxed or delivered, to the address or facsimile number specified for notices on
the applicable signature page hereof; or, as directed to the Borrower or the
Agent, to such other address as shall be designated by such party in a written
notice to the other parties, and as directed to each other party, at such other
address as shall be designated by such party in a written notice to the Borrower
and the Agent.

            (b) All such notices, requests and communications shall, when
transmitted by overnight delivery, or faxed, be effective when delivered for
overnight (next day) delivery, or transmitted by facsimile machine,
respectively, or if delivered, upon delivery, except that notices pursuant to
SECTIONS 2 or 10 of this Agreement shall not be effective until actually
received by the Agent.


                                       68


<PAGE>   70
            (c) The Borrower and the Lenders acknowledge and agree that any
agreement of the parties to receive certain notices by telephone and facsimile
is for their mutual benefit and convenience. Any party shall be entitled to rely
on the authority of any Person purporting to be a Person authorized by any other
party to give such notice and the party relying on such authorization shall not
have any liability to any other Person on account of any action taken or not
taken by such party in reliance upon such telephonic or facsimile notice. The
obligation of the Borrower to repay the Loans shall not be affected in any way
or to any extent by any failure by the Agent to receive written confirmation of
any telephonic or facsimile notice or the receipt by the Agent of a confirmation
which is at variance with the terms understood by the Agent to be contained in
the telephonic or facsimile notice.

        12.5 NOTIFICATION OF ADDRESSES, LENDING OFFICES, ETC. Each Lender shall
notify the Agent in writing of any changes in the address to which notices to
such Lender should be directed, of addresses of its Lending Office, of payment
instructions in respect of all payments to be made to it hereunder and of such
other administrative information as the Agent shall reasonably request.

        12.6 COUNTERPARTS. This Agreement and any amendments, waivers, consents
or supplements hereto may be executed in any number of counterparts, and by
different parties hereto in separate counterparts, each of which when so
executed and delivered shall be deemed an original, but all such counterparts
together shall constitute but one and the same instrument. Each such agreement
shall become effective upon the execution of a counterpart hereof or thereof by
each of the parties hereto or thereto, delivery of each such counterpart to the
Agent, and notification thereof by the Agent has been received by the Borrower
and the Lenders.

        12.7 COSTS AND EXPENSES. The Borrower shall, whether or not the
transactions contemplated hereby shall be consummated, and in addition to costs
and expenses required to be paid at Closing under SECTION 4.1 of this Agreement:

            (a) pay or reimburse Comerica (including in its capacity as the
Agent) within thirty (30) days after demand for all costs and expenses incurred
by Comerica (including in its capacity as the Agent) in connection with the
preparation, delivery, administration and execution of, and any amendment,
supplement, waiver or modification to (in each case, whether or not
consummated), this Agreement, any other Loan Document and any other documents
prepared in connection herewith (including any commitment letter and related
documents preceding this Agreement) or therewith, and the consummation of the
transactions contemplated hereby and thereby, including the reasonable Attorney
Costs incurred by Comerica or Documentation Agent as to any amendments,
supplements, waivers, or modifications, (including in its capacity as the Agent)
with respect hereto and thereto;

            (b) pay or reimburse the Agent and each Lender within thirty (30)
days after demand for all costs and expenses incurred by them in connection with
the enforcement, attempted enforcement, or preservation of any rights or
remedies (including in connection with any "workout" or restructuring regarding
the Loans, and including in any Insolvency Proceeding 


                                       69


<PAGE>   71
or appellate proceeding) under this Agreement, any other Loan Document, and any
such other documents, including Attorney Costs incurred by the Agent and any
Lender; and

            (c) pay or reimburse Comerica (including in its capacity as the
Agent) within thirty (30) days after demand for all reasonable audit,
environmental inspection and review, search and filing, registration and
recording, costs, fees and expenses, incurred or sustained by Comerica
(including in its capacity Agent) in connection with the matters referred to
under clauses (A) and (B) of this SECTION 12.7 of this Agreement.

        12.8 RELIANCE BY LENDERS. All covenants, agreements, representations and
warranties made herein by the Borrower shall, notwithstanding any investigation
by the Lenders or the Agent be deemed to be material to and to have been relied
upon by the Lenders.

        12.9 NO SET-OFFS BY BORROWER. All sums payable by the Borrower pursuant
to this Agreement, the Notes or any of the other Loan Documents shall be payable
without notice or demand and shall be payable in United States Dollars without
set-off or reduction of any manner whatsoever; provided, however, that
notwithstanding the requirement that all payments be made without set-off or
reduction, if any invoice by the Agent for interest, loan fees or letter of
credit commissions incorrectly states that the Borrower owes an amount greater
than the amount actually due, the Borrower pays the amount due on such invoice
and then such error is corrected by Agent or determined as having been made by a
court having jurisdiction pursuant to the terms of this Agreement, then the
Borrower may apply the amount of such overpayment toward future payments due
hereunder or, in the event no further payments will fall due hereunder, recover
such overpayment from the Lenders.

        12.10 SUCCESSORS AND ASSIGNS. The provisions of this Agreement shall be
binding upon and inure to the benefit of the parties hereto and their respective
successors and assigns, except that the Borrower may not assign or transfer any
of its rights or obligations under this Agreement without the prior written
consent of the Agent and each Lender.

        12.11 HEADINGS. Section and subsection headings in this Agreement are
included herein for convenience of reference only and shall not constitute a
part of this Agreement for any other purpose or be given any substantive effect.

        12.12 SEVERABILITY. Whenever possible, each provision of this Agreement,
the Notes and each of the other Loan Documents shall be interpreted in such a
manner as to be valid, legal and enforceable under the applicable law of any
jurisdiction. Without limiting the generality of the foregoing sentence, in case
any provision of this Agreement, the Notes or any of the other Loan Documents
shall be invalid, illegal or unenforceable under the applicable law of any
jurisdiction, the validity, legality and enforceability of the remaining
provisions, or of such provision in any other jurisdiction, shall not in any way
be affected or impaired thereby.

        12.13 NO THIRD PARTIES BENEFITTED. This Agreement is made and entered
into for the sole protection and legal benefit of the Borrower, the Lenders and
the Agent, and their permitted successors and assigns, and except as otherwise
expressly provided in this Agreement, no other 


                                       70


<PAGE>   72
Person shall be a direct or indirect legal beneficiary of, or have any direct or
indirect cause of action or claim in connection with, this Agreement or any of
the other Loan Documents. Neither the Agent nor any Lender shall have any
obligation to any Person not a party to this Agreement or other Loan Documents.

        12.14 RELATIONSHIP OF PARTIES. The relationship between the Borrower, on
the one hand, and the Lenders and the Agent, on the other, is, and at all times
shall remain, solely that of a borrower and lenders. Neither the Lenders nor the
Agent shall under any circumstances be construed to be partners or joint
venturers of the Borrower or any of its Affiliates; nor shall the Lenders nor
the Agent under any circumstances be deemed to be in a relationship of
confidence or trust or a fiduciary relationship with the Borrower or any of its
Affiliates, or to owe any fiduciary duty to the Borrower or any of its
Affiliates. The Lenders and the Agent do not undertake or assume any
responsibility or duty to the Borrower or any of its Affiliates to select,
review, inspect, supervise, pass judgment upon or otherwise inform the Borrower
or any of its Affiliates of any matter in connection with its or their Property,
any Collateral held by the Agent or any Lender or the operations of the Borrower
or any of its Affiliates. The Borrower and each of its Affiliates shall rely
entirely on their own judgment with respect to such matters, and any review,
inspection, supervision, exercise of judgment or supply of information
undertaken or assumed by any Lender or the Agent in connection with such matters
is solely for the protection of the Lenders and the Agent and neither the
Borrower nor any of their Affiliates is entitled to rely thereon.

        12.15 TIME. Time is of the essence as to each term or provision of this
Agreement and each of the other Loan Documents.

        12.16 WAIVER OF PUNITIVE DAMAGES. NOTWITHSTANDING ANYTHING TO THE
CONTRARY CONTAINED IN THIS AGREEMENT, THE BORROWER HEREBY AGREES THAT IT SHALL
NOT SEEK FROM THE LENDERS OR THE AGENT PUNITIVE DAMAGES UNDER ANY THEORY OF
LIABILITY.

        12.17 GOVERNING LAW. EXCEPT AS OTHERWISE EXPRESSLY PROVIDED IN ANY OF
THE LOAN DOCUMENTS, IN ALL RESPECTS, INCLUDING ALL MATTERS OF CONSTRUCTION,
VALIDITY AND PERFORMANCE, THIS AGREEMENT AND THE OBLIGATIONS ARISING HEREUNDER
SHALL BE GOVERNED BY, AND CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE LAWS OF
THE STATE OF CALIFORNIA APPLICABLE TO CONTRACTS MADE AND PERFORMED IN SUCH
STATE, WITHOUT REGARD TO THE PRINCIPLES THEREOF REGARDING CONFLICT OF LAWS, AND
ANY APPLICABLE LAWS OF THE UNITED STATES OF AMERICA.

        12.18 PERSONAL JURISDICTION. THE BORROWER THE AGENT, LENDER AND ALL
ASSIGNEES AND PARTICIPANTS HEREBY IRREVOCABLY AGREE THAT ANY LEGAL ACTION OR
PROCEEDING WITH RESPECT TO THIS AGREEMENT, THE LOAN DOCUMENTS OR ANY OF THE
AGREEMENTS, DOCUMENTS OR INSTRUMENTS DELIVERED IN CONNECTION HEREWITH MAY BE
BROUGHT IN THE COURTS OF THE STATE OF CALIFORNIA OR OF THE UNITED STATES OF
AMERICA IN THE NORTHERN DISTRICT OF CALIFORNIA AS THE AGENT MAY ELECT, AND, BY
EXECUTION AND DELIVERY HEREOF, ACCEPTS AND CONSENTS TO, FOR ITSELF AND IN
RESPECT OF ITS PROPERTY, GENERALLY AND UNCONDITIONALLY, THE JURISDICTION OF THE
AFORESAID COURTS AND AGREES 


                                       71


<PAGE>   73
THAT SUCH JURISDICTION SHALL BE EXCLUSIVE, UNLESS WAIVED BY THE AGENT IN
WRITING, WITH RESPECT TO ANY ACTION OR PROCEEDING BROUGHT HEREUNDER BY THE
BORROWER AGAINST THE AGENT OR ANY LENDER. THE PARTIES HEREBY WAIVE, TO THE FULL
EXTENT PERMITTED BY LAW, ANY RIGHT TO STAY OR TO DISMISS ANY ACTION OR
PROCEEDING BROUGHT BEFORE SAID COURTS ON THE BASIS OF FORUM NON CONVENIENS.

        12.19 WAIVER OF JURY TRIAL. THE BORROWER, EACH LENDER AND THE AGENT,
HEREBY IRREVOCABLY WAIVE THEIR RESPECTIVE RIGHTS TO A JURY TRIAL WITH RESPECT TO
ANY ACTION, CLAIM OR OTHER PROCEEDING ARISING OUT OF ANY DISPUTE IN CONNECTION
WITH THIS AGREEMENT, THE NOTES OR ANY OF THE OTHER LOAN DOCUMENTS, ANY RIGHTS OR
OBLIGATIONS HEREUNDER OF THEREUNDER, OR THE PERFORMANCE OF SUCH RIGHTS AND
OBLIGATIONS.
