1.   Basis of Presentation
     ---------------------

     The accompanying unaudited condensed interim consolidated financial
     statements have been prepared in accordance with generally accepted
     accounting principles for interim financial information and with the
     instructions to Form 10-Q and Rule 10-01 of Regulation S-X.  Accordingly,
     they do not include all of the information and footnotes required by
     generally accepted accounting principles for annual financial statements.
     In the opinion of management, the condensed interim consolidated financial
     statements include all normal recurring adjustments necessary for a fair
     presentation of the information required to be included.  Operating results
     for the three and nine-month periods ended June 30, 1996 are not
     necessarily indicative of the results that may be expected for any future
     periods.  For further information, refer to the annual consolidated
     financial statements and notes thereto for the year ended October 1, 1995
     in the Company's filing on Form 10-K.

     The previous year-end's balance sheet data was derived from audited
     financial statements but does not include all disclosures required by
     generally accepted accounting principles.

2.   Net Income Per Share
     --------------------

     Net income per common and common equivalent share has been computed using
     the weighted average number of common shares outstanding after considering
     the dilutive effect of common stock options and warrants.

3.   Depreciation and Amortization
     -----------------------------

     Depreciation and amortization were approximately $2.2 million and $1.4
     million for the three-month periods ended June 30, 1996 and July 2, 1995,
     respectively, and $6.8 million and $4.3 million for the nine-month periods
     ended June 30, 1996 and July 2, 1995, respectively.

4.   Inventories

5.   Income Taxes
     ------------

     The Company uses the deferral method to account for income taxes under
     Statement of Financial Accounting Standards (SFAS) No. 109, "Accounting for
     Income Taxes".  Valuation allowances are established when necessary to
     reduce deferred tax assets to the amounts expected to be realized.

     The provisions for income taxes for each of the nine months ended June 30,
     1996 and July 2, 1995 are based on the estimated effective income tax rates
     for the fiscal years ending September 29, 1996 and October 1, 1995 of 36%
     and 35%, respectively.

6.   Credit and Borrowing Arrangements
     ---------------------------------

     Interest payments for the third quarter of fiscal years 1996 and 1995 were
     approximately $922 and $425, respectively.  Interest payments for each of
     the nine month periods ended June 30, 1996 and July 2, 1995 were
     approximately $2,382 and $805, respectively.

     On July 31, 1996, the Company increased its revolving credit facility to
     $60.0 million.  This syndicated credit facility with four banks is for
     working capital uses.  The credit facility expires July 31, 1999 and bears
     interest at approximately Libor plus 1.00%.  As of August 5, 1996 the
     Company had available $19.6 million available for borrowing under this
     facility.

7.   Litigation
     ----------

     The Company is a defendant in various legal proceedings incidental to its
     business. While it is not possible to determine the ultimate outcome of
     these actions at this time, management is of the opinion that any unaccrued
     liability resulting from these claims would not have a material adverse
     effect on the Company's consolidated financial position or results of
     operations.

8.   Acquisition
     -----------

     On November 9, 1995, the Company acquired JD Technical Services, Inc., of
     Washington, Missouri, a provider of nuclear medicine imaging system
     remanufacturing, as well as a nationwide provider of multi-vendor service
     and support.  The Company issued 138 shares of common stock at the
     average closing price of the Company's common stock during a specified
     period, for a total price of $1.7 million, in exchange for all the
     outstanding stock of JD Technical.  The transaction was accounted for as a
     pooling of interests.  Prior period financial statements have not been
     restated, as the operations of JD Technical were not material to the
     financial position or the results of operations of the Company at the time
     of acquisition.

9.   Preferred Share Purchase Rights Plan
     ------------------------------------

     In April 1996, the Company's Board of Directors adopted a Preferred Share
     Purchase Rights Plan (the "Rights Plan").  Under the Rights Plan, a
     dividend of one preferred share purchase right (a "Right") for each
     outstanding share of common stock, without par value (the "Common Shares"),
     of the Company was declared.  Each Right entitles the registered holder to
     purchase from the Company one one-hundredth of a share of Series A Junior
     Participating Preferred Stock, without par value (the "Preferred Stock"),
     at a price of seventy dollars ($70.00) per one one-hundredth of a Preferred
     Share.  Each one one-hundredth of a share of Preferred Stock has
     designations and the powers, preferences and rights, and the
     qualifications, limitations and restrictions which make its value
     approximately equal to the value of a Common Share.  In general, the Rights
     are exercisable upon the commencement of, or announcement of an intention
     to make, a tender offer or exchange offer, the consummation of which would
     result in the beneficial ownership by a person or group of 15% or more of
     such outstanding Common Shares.  The Rights expire in April 2006 unless the
     expiration date is extended or unless the Rights are earlier redeemed by
     the Company.

     The Rights Plan is designed to provide an adequate opportunity for the
     Company's Board of Directors to consider and evaluate all strategic
     alternatives of the Company in the event an unsolicited attempt is made to
     acquire the Company.  The Rights are intended to enable all of the
     Company's shareholders to realize the full value of their investment and to
     provide for fair and equal treatment for all shareholders.  The adoption of
     the Rights Plan will not, nor is it intended to, prevent all takeover
     actions.  The Rights are not being distributed in response to any proposal
     to acquire the Company.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
- --------------------------------------------------------------------------------
OF OPERATIONS
- --------------

LIQUIDITY AND CAPITAL RESOURCES

Net cash provided by operating activities during the first nine months of fiscal
1996 was $0.6 million compared to $3.1 million in the first nine months of
fiscal 1995. The decrease in cash provided from operations were primarily
attributable to increases in accounts receivables, as revenues grew 30.7% in
1996 over the same nine month period in 1995.

Cash used in investing activities decreased from $9.3 million to $4.8 million.
Most of the decrease was due to the Company previously providing funding to
Community Health Computing (CHC) during the first nine months of fiscal 1995
prior to the Company's acquisition of such corporation.  Cash generated by
financing activities decreased $0.7 million primarily as a result of a period to
period decrease in incremental borrowings.  Additionally, financing cash inflows
were augmented by a $3.3 million incremental increase in stock option exercises,
employee stock purchases, and dividend reinvestments.

As a result of the Company's operating, investing and financing activities, the
Company's cash and cash equivalents decreased by $2.4 million, from $7.6 million
to $5.2 million in the first nine months of fiscal 1996 compared to a decrease
of $1.7 million in the first nine months of fiscal 1995.

On July 31, 1996, the Company increased its revolving credit facility to $60.0
million.  This syndicated credit facility with four banks is for working capital
uses.  The credit facility expires July 31, 1999 and bears interest at
approximately Libor plus 1.00%.  As of August 5, 1996 the Company had available
$19.6 million available for borrowing under this facility.

The Company believes that its cash, cash equivalents, cash flows from operating
activities and, if necessary, remaining available lines of credit will be able
to fund the Company's cash flow requirements for the current fiscal year.  On a
longer-term basis, the Company may decide to increase its sources of capital in
response to business conditions or to pursue new business opportunities.  Such
sources of capital might include private or public equity or debt offerings.
There can be no assurance that such additional financing resources will be
available and/or on terms favorable to the Company.

RESULTS OF OPERATIONS

REVENUES AND GROSS MARGIN:
The Company's two business units are Medical Systems and Healthcare Information
Systems (HCIS).

The Medical Systems business unit includes Nuclear Medicine, Radiation Therapy
Planning (RTP), and  Digital Systems Angiography (DSA) equipment products, as
well as services relating to those products. Medical Systems product revenues
increased from $32.7 million in the third quarter of fiscal 1995 to $41.5
million in the third quarter of fiscal 1996, and increased from $96.7 million to
$117.4 million in the first nine months of 1995 and 1996, respectively.  This
product revenue increase was primarily due to an 18.7%, or $5.9 million,
increase in Nuclear Medicine product revenues for the third quarter of fiscal
1996 compared with the third quarter of fiscal 1995.  For the comparable nine
month periods, Nuclear Medicine product revenue increased 18.8%, or $17.2
million, over the first nine months of fiscal 1995. These increases were offset
by a $0.3 and $2.8 million decrease in DSA product sales for the third quarter
of fiscal 1996 and the first nine months of fiscal 1996, respectively, compared
with the same periods in the previous fiscal year, as that product continues to
mature.  Medical Systems service revenues increased from $10.8 million to $11.8
million in the third quarters of fiscal 1995 and 1996, respectively, and
increased from $30.7 million to $34.1 million in the first nine months of fiscal
1995 and 1996, respectively, primarily as a result of the continued increase in
the installed product base.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
- --------------------------------------------------------------------------------
OF OPERATIONS (CONTINUED)
- -------------------------

Medical Systems product revenue represented 89.5% and 96.2% of the Company's
total product revenue during the third quarters of fiscal 1996 and 1995,
respectively, and 91.0% and 95.3% of the Company's total product revenue during
the first nine months of fiscal 1996 and 1995, respectively. The geographical
mix of Medical Systems product revenues for the third quarter of fiscal 1996 was
75.8% in North America, 11.9% in Europe, and 12.3% in the rest of the world,
primarily Latin America and Asia, compared with 80.3% in North America, 15.2% in
Europe, and 4.5% in the rest of the world in the third quarter of fiscal 1995.
The geographical mix of Medical Systems product revenues for the first nine
months of fiscal 1996 was 74.7% in North America, 14.2% in Europe, and 11.1% in
the rest of the world, primarily Latin America and Asia, compared with 75.6% in
North America, 16.2% in Europe, and 8.2% in the rest of the world in the first
nine months of fiscal 1995.  The mix of product revenues as a percent of total
Medical Systems product revenues for the third quarters of fiscal 1996 and 1995
were 94.4% and 96.3%, respectively, for Nuclear Medicine, 4.9% and 1.7%,
respectively, for RTP, and 0.7% and 2.0%, respectively, for DSA.  The mix of
product revenues as a percent of total Medical Systems product revenues for the
first nine months of fiscal 1996 and 1995 were 95.3% and 94.2%, respectively,
for Nuclear Medicine, 4.1% and 2.1%, respectively, for RTP, and 0.7% and 3.7%,
respectively, for DSA.

Medical Systems product margins increased from 36.5% to 39.2% for the third
quarters of fiscal 1995 and 1996, respectively.  For the comparable nine month
periods, Medical Systems product margins increased from 37.3% to 38.1% for
fiscal 1995 and 1996, respectively.  Service margins for Medical Systems
decreased from 34.6% in the third quarter of fiscal 1995 to 32.8% in the third
quarter of 1996.  For the comparable nine month periods, however, service
margins for Medical Systems increased from 30.9% in fiscal 1995 to 33.0% in
fiscal 1996, as the installed customer base increased, product reliability
increased and overall costs were reduced.

HCIS includes products comprising the hardware, software and related
implementation of systems designed to manage information within the radiology
and laboratory departments of healthcare organizations, as well as service
related to those products.  During the first nine months of fiscal 1995, the
Company's HCIS product mix included radiology products offered by the Company
and ADAC/SD&G Healthcare Systems (SD&G), which the Company acquired in November
1993.  In July 1995, the Company also acquired Community Health Computing (CHC),
which provided the Company with an additional radiology product, as well as a
laboratory product.  The HCIS business unit now represents the combined
businesses of SD&G, CHC, and the Company's existing radiology business.

HCIS product revenues increased from $1.3 million to $4.9 million from the third
quarter of fiscal 1995 compared with the third quarter of fiscal 1996 and
increased from $4.8 million to $11.7 million from the first nine months of
fiscal 1995 compared with the first nine months of fiscal 1996.  HCIS service
revenues increased from $0.8 million in the third quarter of fiscal 1995 to $4.2
million in the third quarter of fiscal 1996, and increased from $2.4 million in
the first nine months of fiscal 1995 to $12.7 million in the first nine months
of fiscal 1996.  These increases are attributable to additional radiology and
laboratory products acquired in, or developed subsequent to, the acquisition of
CHC previously discussed.

All HCIS sales are in North America.  For the third quarter of fiscal 1996 and
1995, radiology product revenues represented 49.3% and 100%, respectively, of
HCIS product revenues, and laboratory product revenues represented 50.7% and
0.0%, respectively.  For the nine month periods in fiscal 1996 and 1995,
respectively, radiology product revenues represented 54.1% and 100%,
respectively, of HCIS product revenues, and laboratory product revenues
represented 45.9% and 0.0%, respectively.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
- --------------------------------------------------------------------------------
OF OPERATIONS (CONTINUED)
- -------------------------

HCIS product margins for the third quarters of fiscal 1995 and 1996 were 41.2%
and 34.5%, respectively, while for the first nine months in fiscal 1995 and
1996, the HCIS product margins were 46.5% and 42.5%, respectively.  The decrease
in product margins is due to the mix in hardware and software components of
shipments.  HCIS service margins increased from 44.8% to 54.3% from the third
quarter in fiscal 1995 to the third quarter in fiscal 1996, and increased from
33.5% to 52.3% for the first nine months of fiscal 1996 compared with the same
time period in fiscal 1995, primarily due to obtaining a relatively large
installed base of laboratory product customers when the Company acquired CHC.

OPERATING AND OTHER EXPENSES:
Overall operating expenses as a percentage of revenues for the third quarter of
fiscal 1996 compared with the third quarter of fiscal 1995 increased to 26.4%
from 25.8%. This increase is primarily attributable to the acquired CHC business
which added goodwill amortization and additional administrative and
infrastructure costs related to the HCIS business unit.  As a percentage of
revenue for the third quarters of fiscal 1996 and 1995, marketing and sales
expenses decreased to 15.3% from 15.8%, research and development remained
relatively consistent at 5.1% and 5.0%, respectively, and general and
administrative expenses increased to 5.7% from 5.0%.  The $1.3 million increase
in general and administrative expenses over the prior year's third quarter
resulted from the additional administrative and infrastructure costs related to
the acquired HCIS business unit.  For the comparable nine month periods in
fiscal 1996 and 1995, overall operating expenses as a percentage of revenues
remained consistent at 26.5% and 26.3%, respectively.  As a percentage of
revenue for the first nine months of fiscal 1996 and 1995, marketing and sales
expenses decreased to 15.0% from 16.3%, research and development expenses
decreased to 5.2% from 5.4%, and general and administrative expenses increased
to 6.0% from 4.6%.

Other expense, net, increased to $0.8 million in the third quarter of fiscal
1996 from $0.2 million in the third quarter of fiscal 1995.  For the comparable
nine month periods, other expense, net, increased to $2.5 million from $0.6
million.  These increases resulted from the Company carrying higher short-term
bank borrowings during fiscal 1996, due to the acquisition of CHC.

INCOME TAXES:
The effective tax rate for the third quarters of fiscal 1996 and 1995 were 36%
and 34%, respectively.  The effective tax rate for the first nine months of
fiscal 1996 was 36%, compared with an effective tax rate of 35% for the first
nine months of fiscal 1995.  These rates are approximately equal to the
Company's statutory Federal tax rate after utilization of business tax credits.

OTHER:
In order to maintain successful operating results in the highly competitive
industry in which the Company does business, the Company must continue to
produce and market innovative products equal to or better than those of its
competitors.  Within the industry, there is also uncertainty associated with the
potential response of customers to new private and legislative health care cost
containment initiatives, which may affect the size of the marketplace, the
receipt of orders for new products, and pricing.  Although the Company has been
able to develop and market advanced, innovative and cost effective new products
in recent years, and has been able to increase its market share in the nuclear
medicine industry, there is no assurance that this will continue.

           (g) Purpose.  Borrower shall use the proceeds of the Loans 
               -------
     (i) first, to repay on the Closing Date all indebtedness outstanding under
     (A) the Amended and Restated Credit Agreement dated as of August 15, 1995
     between Borrower and ABN and (B) the Credit Agreement dated as of
     August 12, 1993 between Borrower and Sanwa (such agreements, as amended
     from time to time prior to the date hereof, the "Prior Credit Agreements")
                                                      -----------------------
     and (ii) thereafter, for Borrower's general corporate needs.

     2.02.  Commitment Reductions, Etc.
            ---------------------------

            (a)  Reduction or Cancellation of Commitments.  Borrower may, upon
                 ----------------------------------------
three (3) Business Days written notice to Agent, permanently reduce the Total
Commitment by the amount of one million Dollars ($1,000,000) or an integral
multiple of one million Dollars ($1,000,000) in excess thereof or cancel the
Total Commitment in its entirety; provided, however, that:
                                  --------  -------

                                      23
<PAGE>
 
                 (i)   Borrower may not reduce the Total Commitment prior to the
           Maturity Date, if, after giving effect to such reduction, the
           aggregate principal amount of all Loans then outstanding would exceed
           the Total Commitment; and

                (ii)   Borrower may not cancel the Total Commitment prior to the
           Maturity Date, if, after giving effect to such cancellation, any
           Loans would then remain outstanding.

            (b)  Effect of Commitment Reductions.  From the effective date of
                 -------------------------------
any reduction of the Total Commitment, the Commitment Fees payable pursuant to
Subparagraph 2.03(b) shall be computed on the basis of the Total Commitment as
- --------------------
so reduced. Once reduced or cancelled, the Total Commitment may not be increased
or reinstated without the prior written consent of all Lenders. Any reduction of
the Total Commitment pursuant to Subparagraph 2.02(a) shall be applied ratably
                                 --------------------
to reduce each Lender's Commitment in accordance with clause (i) of Subparagraph
                                                      --------------------------
2.08(a).
- -------

     2.03.  Fees.
            ----

            (a)  Agent's Fee.  Borrower shall pay to Agent, for its own 
                 -----------
account, agent's fees and other compensation in the amounts and at the times set
forth in the Agent's Fee Letter.

            (b)  Commitment Fees.  Borrower shall pay to Agent, for the ratable 
                 ---------------
benefit of the Lenders as provided in clause (iii) of Subparagraph 2.08(a),
                                      ------------------------------------
nonrefundable commitment fees (the "Commitment Fees") equal to the Commitment
                                    ---------------
Fee Percentage on the daily average Unused Commitment for the period beginning
on the date of this Agreement and ending on the Maturity Date. The Commitment
Fee Percentage shall be determined as provided in the Pricing Grid and may
change for each calendar quarter. Borrower shall pay the Commitment Fees in
arrears on the last day in each March, June, September and December and on the
Maturity Date (or if the Total Commitment is cancelled on a date prior to the
Maturity Date, on such prior date).

     2.04.  Prepayments.
            -----------

            (a)  Terms of all Prepayments.  Upon the prepayment of any Loan
                 ------------------------
(whether such prepayment is an optional prepayment under Subparagraph 2.04(b), a
                                                         --------------------
mandatory prepayment required by Subparagraph 2.04(c) or a mandatory prepayment
                                 --------------------
required by any other provision of this Agreement or the other Credit Documents,
including, without limitation, a prepayment upon acceleration), Borrower shall
pay to the Lender which made such Loan (i) all accrued interest to the date of
such prepayment on the amount prepaid and (ii) if such prepayment is the
prepayment of a LIBOR Loan on a day other than the

                                      24
<PAGE>
 
last day of an Interest Period for such LIBOR Loan, all amounts payable to such
Lender pursuant to Paragraph 2.11.
                   --------------

            (b)  Optional Prepayments.  At its option, Borrower may, upon three
                 --------------------
(3) Business Days notice to Agent, prepay the Loans in any Borrowing in part, in
an aggregate principal amount of $1,000,000 or more, or in whole; except that
Borrower may prepay the Loans in any Borrowing consisting of Base Rate Loans on
the last Business Day in any fiscal quarter of Borrower upon same day notice to
Agent if Borrower delivers such notice to Agent not later than 1:00 p.m. on the
date of such prepayment.

            (c)  Mandatory Prepayments.  If, at any time, the aggregate 
                 ---------------------
principal amount of all Loans then outstanding exceeds the Total Commitment at
such time, Borrower shall immediately prepay Loans in an aggregate principal
amount equal to such excess.

     2.05.  Other Payment Terms.
            -------------------

            (a)  Place and Manner.  Borrower shall make all payments due to each
                 ----------------
Lender or Agent hereunder by payments to Agent at Agent's office located at the
address specified in Paragraph 8.01, with each payment due to a Lender to be for
                     --------------
the account of such Lender and such Lender's Applicable Lending Office. Borrower
shall make all payments hereunder in lawful money of the United States and in
same day or immediately available funds not later than 12:00 noon on the date
due, except that Borrower may make prepayments of the Loans in a Borrowing
consisting of Base Rate Loans on the last Business Day of a fiscal quarter as
late as 1:00 p.m. Agent shall promptly disburse to each Lender each payment
received by Agent for the account of such Lender.

            (b)  Date.  Whenever any payment due hereunder shall fall due on a
                 ----
day other than a Business Day, such payment shall be made on the next succeeding
Business Day, and such extension of time shall be included in the computation of
interest or fees, as the case may be.

            (c)  Late Payments.  If any amounts required to be paid by Borrower
                 -------------
under this Agreement or the other Credit Documents (including, without
limitation, principal or interest payable on any Loan, any fees or other
amounts) remain unpaid after such amounts are due, Borrower shall pay interest
on the aggregate, outstanding balance of such amounts from the date due until
those amounts are paid in full at a per annum rate equal to the Base Rate plus
two percent (2.00%), such rate to change from time to time as the Base Rate
shall change.

            (d)  Application of Payments.  All payments hereunder shall be
                 -----------------------
applied first to unpaid fees, costs and expenses then due and payable under this
Agreement or the other Credit Documents, second to accrued interest then due and
payable under this Agreement or the other

                                      25
<PAGE>
 
Credit Documents, seconds to accrued interest then due and payable under this
Agreement or the other Credit Documents and finally to reduce the principal
amount of outstanding Loans.

            (e)  Failure to Pay Agent.  Unless Agent shall have received notice
                 --------------------
from Borrower at least one (1) Business Day prior to the date on which any
payment is due to the Lenders hereunder that Borrower will not make such payment
in full, Agent shall be entitled to assume that Borrower has made or will make
such payment in full to Agent on such date and Agent may, in reliance upon such
assumption, cause to be paid to the Lenders on such due date an amount equal to
the amount then due such Lenders. If and to the extent Borrower shall not have
so made such payment in full to Agent, each such Lender shall repay to Agent
forthwith on demand such amount distributed to such Lender together with
interest thereon, for each day from the date such amount is distributed to such
Lender until the date such Lender repays such amount to Agent, at (i) the
Federal Funds Rate for the first three (3) days and (ii) the per annum rate
applicable to Base Rate Loans thereafter. A certificate of Agent submitted to
any Lender with respect to any amounts owing by such Lender under this
Subparagraph 2.05(e) shall be conclusive absent manifest error.
- --------------------

     2.06.  Notes and Interest Account.
            --------------------------

            (a)  Notes.  The obligation of Borrower to repay the Loans made by
                 -----
each Lender and to pay interest thereon at the rates provided herein shall be
evidenced by a promissory note in the form of Exhibit D (individually, a "Note")
                                              ---------                   ----
which note shall be (i) payable to the order of such Lender, (ii) in the amount
of such Lender's Commitment, (iii) dated the Closing Date and (iv) otherwise
appropriately completed. Borrower authorizes each Lender to record on the
schedule annexed to such Lender's Note the date and amount of each Loan made by
such Lender and of each payment or prepayment of principal thereon made by
Borrower, and agrees that all such notations shall constitute prima facie
evidence of the matters noted; provided, however, that any failure by a Lender
                               --------  -------
to make any such notation shall not affect the Obligations. Borrower further
authorizes each Lender to attach to and make a part of such Lender's Note
continuations of the schedule attached thereto as necessary.

            (b)  Interest Account.  Borrower authorizes Agent to record in an
                 ----------------
account or accounts maintained by Agent on its books (the "Interest Account")
                                                           ----------------
(i) the interest rates applicable to all Loans and the effective dates of all
changes thereto, (ii) the Interest Period for each LIBOR Loan, (iii) the date
and amount of each principal and interest payment on each Loan and (iv) such
other information as Agent may determine is necessary for the computation of
interest payable by Borrower hereunder.

                                      26

     2.07.  Loan Funding.
            -------------

            (a)  Lender Funding and Disbursement to Borrower.  Each Lender 
                 -------------------------------------------
shall, before 12:00 noon on the date of each Borrowing, make available to Agent
at Agent's office specified in Paragraph 8.01, in same day or immediately
                               --------------
available funds, such Lender's Proportionate Share of such Borrowing. After
Agent's receipt of such funds and upon satisfaction of the applicable conditions
set forth in Section III, Agent shall promptly disburse such funds to Borrower
             -----------
in same day or immediately available funds. Unless otherwise directed by
Borrower, Agent shall disburse the proceeds of each Borrowing by disbursement to
the account or accounts specified in the applicable Notice of Borrowing.

            (b)  Lender Failure to Fund.  Unless Agent shall have received 
                 ----------------------
notice from a Lender prior to the date of any Borrowing that such Lender will
not make available to Agent such Lender's Proportionate Share of such Borrowing,
Agent shall be entitled to assume that such Lender has made or will make such
portion available to Agent on the date of such Borrowing in accordance with
Subparagraph 2.07(a), and Agent may on such date, in reliance upon such
- --------------------
assumption, disburse or otherwise credit to Borrower a corresponding amount. If
any Lender does not make the amount of its Proportionate Share of any Borrowing
available to Agent on or prior to the date of such Borrowing, such Lender shall
pay to Agent, on demand, interest which shall accrue on such amount from the
date of such Borrowing until such amount is paid to Agent at rates equal to (i)
the daily Federal Funds Rate during the period from the date of such Borrowing
through the third Business Day thereafter and (ii) the rate applicable to Base
Rate Loans thereafter. A certificate of Agent submitted to any Lender with
respect to any amounts owing under this Subparagraph 2.07(b) shall be conclusive
                                        --------------------
absent manifest error. If the amount of any Lender's Proportionate Share of any
Borrowing is not paid to Agent by such Lender within three (3) Business Days
after the date of such Borrowing, Borrower shall repay such amount to Agent, on
demand, together with interest thereon, for each day from the date such amount
was disbursed to Borrower until the date such amount is repaid to Agent, at the
interest rate applicable at the time to the Loans comprising such Borrowing.

            (c)  Lenders' Obligations Several.  The failure of any Lender to
                 ----------------------------
make the Loan to be made by it as part of any Borrowing shall not relieve any
other Lender of its obligation hereunder to make its Loan on the date of such
Borrowing, but no Lender shall be obligated in any way to make any Loan which
another Lender has failed or refused to make or otherwise be in any way
responsible for the failure or refusal of any other Lender to make any Loan
required to be made by such other Lender on the date of any Borrowing.

     2.08.  Pro Rata Treatment.
            ------------------

            (a)  Borrowings, Commitment Reductions, Etc.  Except as otherwise
                 --------------------------------------
provided herein:

                 (i)     Each Borrowing and reduction of the Total Commitment
           shall be made or shared among the Lenders pro rata according to their
           respective Proportionate Shares;

                 (ii)    Each payment of principal of Loans in any Borrowing
           shall be shared among the Lenders which made or funded the Loans in
           such Borrowing pro rata according to the respective unpaid principal
           amounts of such Loans so made or funded by such Lenders;

                 (iii)   Each payment of interest on Loans in any Borrowing 
           shall be shared among the Lenders which made or funded the Loans in
           such Borrowing pro rata according to (A) the respective unpaid
           principal amounts of such Loans so made or funded by such Lenders and
           (B) the dates on which such Lenders so made or funded such Loans;

                 (iv)    Each payment of Commitment Fees shall be shared among 
           the Lenders pro rata according to (A) their respective Proportionate
           Shares and (B) in the case of each Lender which becomes a Lender
           hereunder after the date hereof, the date upon which such Lender so
           became a Lender;

                 (v)     Each payment of interest (other than interest on Loans)
           shall be shared among the Lenders and Agent owed the amount upon
           which such interest accrues pro rata according to (A) the respective
           amounts so owed such Lenders and Agent and (B) the dates on which
           such amounts became owing to such Lenders and Agent; and

                 (vi)    All other payments under this Agreement and the other
           Credit Documents shall be for the benefit of the Person or Persons
           specified.

            (b)  Sharing of Payments, Etc.  If any Lender shall obtain any
                 ------------------------
payment (whether voluntary, involuntary, through the exercise of any right of
setoff, or otherwise) on account of Loans owed to it in excess of its ratable
share of payments on account of such Loans obtained by all Lenders entitled to
such payments, such Lender shall forthwith purchase from the other Lenders such
participations in the Loans as shall be necessary to cause such purchasing
Lender to share the excess payment ratably with each of them; provided, however,
                                                              --------  -------
that if all or any portion of such excess payment is thereafter recovered from
such purchasing Lender, such purchase shall be rescinded and each other Lender
shall repay to the purchasing Lender the purchase price to the
     
                                      28
<PAGE>
 
extent of such recovery together with an amount equal to such other Lender's
ratable share (according to the proportion of (i) the amount of such other
Lender's required repayment to (ii) the total amount so recovered from the
purchasing Lender) of any interest or other amount paid or payable by the
purchasing Lender in respect of the total amount so recovered. Borrower agrees
that any Lender so purchasing a participation from another Lender pursuant to
this Subparagraph 2.08(b) may, to the fullest extent permitted by law, exercise
     --------------------
all its rights of payment (including the right of setoff) with respect to such
participation as fully as if such Lender were the direct creditor of Borrower in
the amount of such participation.

     2.09.  Change of Circumstances.
            -----------------------

            (a)  Inability to Determine Rates.  If, on or before the first day
                 ----------------------------
of any Interest Period for any LIBOR Loan, (i) any Lender shall advise Agent
that the LIBO Rate for such Interest Period cannot be adequately and reasonably
determined due to the unavailability of funds in or other circumstances
affecting the London interbank market or (ii) any Lender shall advise Agent that
the rate of interest for such Loan does not adequately and fairly reflect the
cost to such Lender of making or maintaining such LIBOR Loan, Agent shall
immediately give notice of such condition to Borrower and the other Lenders.
After the giving of any such notice and until Agent shall otherwise notify
Borrower that the circumstances giving rise to such condition no longer exist,
Borrower's right to request the making of or conversion to, and the Lenders'
obligations to make or convert to LIBOR Loans shall be suspended. Any LIBOR
Loans outstanding at the commencement of any such suspension shall be converted
at the end of the then current Interest Period for such LIBOR Loans into a Base
Rate Loans unless such suspension has then ended.

            (b)  Illegality.  If, after the date of this Agreement, the adoption
                 ----------
of any Governmental Rule, any change in any Governmental Rule or the application
or requirements thereof (whether such change occurs in accordance with the terms
of such Governmental Rule as enacted, as a result of amendment or otherwise),
any change in the interpretation or administration of any Governmental Rule by
any Governmental Authority, or compliance by any Lender with any request or
directive (whether or not having the force of law) of any Governmental Authority
(a "Change of Law") shall make it unlawful or impossible for any Lender to make
    -------------
or maintain any LIBOR Loan, such Lender shall immediately notify Agent and
Borrower of such Change of Law. Upon receipt of such notice, (i) Borrower's
right to request the making of or conversion to, and such Lender's obligation to
make or convert to LIBOR Loans shall be terminated, and (ii) Borrower shall, at
the request of such Lender, either (A) pursuant to Subparagraph 2.01(d) convert
                                                   --------------------
any such then

                                      29
<PAGE>
 
outstanding LIBOR Loans into Base Rate Loans at the end of the current Interest
Period for such LIBOR Loans or (B) immediately repay or convert any such LIBOR
Loans if such Lender shall notify Borrower that such Lender may not lawfully
continue to fund and maintain such LIBOR Loans. Any conversion or prepayment of
LIBOR Loans made pursuant to the preceding sentence prior to the last day of an
Interest Period for such LIBOR Loans shall be deemed a prepayment thereof for
purposes of Paragraph 2.11. After any Lender notifies Agent and Borrower of such
            --------------
a Change of Law and until such Lender notifies Agent and Borrower that it is no
longer unlawful or impossible for such Lender to make or maintain a LIBOR Loan,
all Loans of such Lender shall be Base Rate Loans.

            (c)  Increased Costs.  If, after the date of this Agreement, any
                 ---------------
Change of Law:

                 (i)     Shall subject any Lender to any tax, duty or other
           charge with respect to any LIBOR Loan, or shall change the basis of
           taxation of payments by Borrower to any Lender on such a LIBOR Loan
           or in respect to such a LIBOR Loan under this Agreement (except for
           changes in the rate of taxation on the overall net income of any
           Lender imposed by its jurisdiction of incorporation or the
           jurisdiction in which its principal executive office is located); or

                 (ii)    Shall impose, modify or hold applicable any reserve
           (excluding any Reserve Requirement or other reserve to the extent
           included in the calculation of the LIBO Rate for any Loans), special
           deposit or similar requirement against assets held by, deposits or
           other liabilities in or for the account of, advances or loans by, or
           any other acquisition of funds by any Lender for any LIBOR Loan; or

                 (iii)   Shall impose on any Lender any other condition related
           to any LIBOR Loan or such Lender's Commitment;

And the effect of any of the foregoing is to increase the cost to such Lender of
making, renewing, or maintaining any such LIBOR Loan or its Commitment or to
reduce any amount receivable by such Lender hereunder; then Borrower shall from
time to time, within five (5) days after demand by such Lender, pay to such
Lender additional amounts sufficient to reimburse such Lender for such increased
costs or to compensate such Lender for such reduced amounts. A certificate as to
the amount of such increased costs or reduced amounts, submitted by such Lender
to Borrower shall, in the absence of manifest error, be conclusive and binding
on Borrower for all purposes. The obligations of Borrower under this
Subparagraph 2.09(c) shall survive the payment
- --------------------

                                      30
<PAGE>
 
and performance of the Obligations and the termination of this Agreement.

            (d)  Capital Requirements.  If, after the date of this Agreement,
                 --------------------
any Lender determines that (i) any Change of Law affects the amount of capital
required or expected to be maintained by such Lender or any Person controlling
such Lender (a "Capital Adequacy Requirement") and (ii) the amount of capital
                ----------------------------
maintained by such Lender or such Person which is attributable to or based upon
the Loans, the Commitments or this Agreement must be increased as a result of
such Capital Adequacy Requirement (taking into account such Lender's or such
Person's policies with respect to capital adequacy), Borrower shall pay to such
Lender or such Person, within five (5) days after demand of such Lender, such
amounts as such Lender or such Person shall determine are necessary to
compensate such Lender or such Person for the increased costs to such Lender or
such Person of such increased capital. A certificate of any Lender setting forth
in reasonable detail the computation of any such increased costs, delivered by
such Lender to Borrower shall, in the absence of manifest error, be conclusive
and binding on Borrower for all purposes. The obligations of Borrower under this
Subparagraph 2.09(d) shall survive the payment and performance of the
- --------------------
Obligations and the termination of this Agreement.

            (e)  Mitigation.  Any Lender which becomes aware of (i) any Change
                 ----------
of Law which will make it unlawful or impossible for such Lender to make or
maintain any LIBOR Loan or (ii) any Change of Law or other event or condition
which will obligate Borrower to pay any amount pursuant to Subparagraph 2.09(c)
                                                           --------------------
or Subparagraph 2.09(d) shall notify Borrower and Agent thereof as promptly as
   --------------------
practical. If any Lender has given notice of any such Change of Law or other
event or condition and thereafter becomes aware that such Change of Law or other
event or condition has ceased to exist, such Lender shall notify Borrower and
Agent thereof as promptly as practical. Each Lender affected by any Change of
Law which makes it unlawful or impossible for such Lender to make or maintain
any LIBOR Loan or to which Borrower is obligated to pay any amount pursuant to
Subparagraph 2.09(c) or Subparagraph 2.09(d) shall use reasonable commercial
- --------------------    --------------------
efforts (including changing the jurisdiction of its Applicable Lending Office)
to avoid the effect of such Change of Law or to avoid or materially reduce any
amounts which Borrower is obligated to pay pursuant to Subparagraph 2.09(c) or
                                                       --------------------

     2.10.  Taxes on Payments.
            -----------------

            (a)  Payments Free of Taxes.  All payments made by Borrower under
                 ----------------------
this Agreement and the other Credit Documents shall be made free and clear of,
and without deduction or withholding for or on account of, any present or future
income, stamp or other taxes, levies, imposts, duties, charges, fees, deductions
or withholdings, now or hereafter imposed, levied, collected, withheld or
assessed by any Governmental Authority (except net income taxes and franchise
taxes in lieu of net income taxes imposed on Agent or any Lender by its
jurisdiction of incorporation or the jurisdiction in which its Applicable
Lending Office is located) (all such non-excluded taxes, levies, imposts,
duties, charges, fees, deductions and withholdings being hereinafter called
"Taxes"). If any Taxes are required to be withheld from any amounts payable to
 -----
Agent or any Lender hereunder or under the other Credit Documents, the amounts
so payable to Agent or such Lender shall be increased to the extent necessary to
yield to Agent or such Lender (after payment of all Taxes) interest or any such
other amounts payable hereunder at the rates or in the amounts specified in this
Agreement and the other Credit Documents. Whenever any Taxes are payable by
Borrower, as promptly as possible thereafter, Borrower shall send to Agent for
its own account or for the account of such Lender, as the case may be, a
certified copy of an original official receipt received by Borrower showing
payment thereof. If Borrower fails to pay any Taxes when due to the appropriate
taxing authority or fails to remit to Agent the required receipts or other
required documentary evidence, Borrower shall indemnify Agent and the Lenders
for any incremental taxes, interest or penalties that may become payable by
Agent or any Lender as a result of any such failure. The obligations of Borrower
under this Subparagraph 2.10(a) shall survive the payment and performance of the
           --------------------
Obligations and the termination of this Agreement.

            (b)  Withholding Exemption Certificates.  On or prior to the date of
                 ----------------------------------
the initial Borrowing or, if such date does not occur within thirty (30) days
after the date of this Agreement, by the end of such 30-day period, each Lender
which is not organized under the laws of the United States of America or a state
thereof shall deliver to Borrower and Agent two duly completed copies of United
States Internal Revenue Service Form 1001 or 4224 (or successor applicable
form), as the case may be, certifying in each case that such Lender is entitled
to receive payments under this Agreement without deduction or withholding of any
United States federal income taxes. Each Lender which delivers to Borrower and
Agent a Form 1001 or 4224 pursuant to the immediately preceding sentence further
undertakes to deliver to Borrower and Agent two further copies of Form 1001 or
4224 (or successor applicable forms), as the case may be, on or before the date
that any such form expires or becomes

                                      32
<PAGE>
 
obsolete or after the occurrence of any event requiring a change in the most
recent form previously delivered by such Lender to Borrower and Agent,
certifying that such Lender is entitled to receive payments under this Agreement
without deduction or withholding of any United States federal income taxes. Each
Lender which is not organized under the laws of the United States of America or
a state thereof further agrees (i) promptly to notify Agent and Borrower of any
change of circumstances (including without limitation any change in any treaty,
law or regulation) which would prevent such Lender from receiving payments
hereunder without any deduction or withholding of United States federal income
tax and (ii) to furnish to Agent and Borrower any other manner of certification
as Agent or Borrower may reasonably request to establish the right of such
Lender to receive payments hereunder without any deduction or withholding of
United States federal income tax.

            (c)  Mitigation.  If Agent or any Lender claims any additional 
                 ----------
amounts to be payable to it pursuant to this Paragraph 2.10, such Person shall
                                             --------------
use reasonable commercial efforts to file any certificate or document requested
in writing by Borrower (including without limitation copies of Internal Revenue
Service Form 1001 (or successor forms) reflecting a reduced rate of withholding)
or to change the jurisdiction of its Applicable Lending Office if the making of
such a filing or such change in the jurisdiction of its Applicable Lending
Office would avoid the need for or materially reduce the amount of any such
additional amounts which may thereafter accrue and if, in the reasonable opinion
of such Person, in the case of a change in the jurisdiction of its Applicable
Lending Office, such change would not be disadvantageous to such Person or
contrary to such Person's normal banking practices.

            (d)  Tax Returns.  Nothing contained in this Paragraph 2.10 shall 
                 -----------
require Agent or any Lender to make available any of its tax returns (or any
other information relating to its taxes which it deems to be confidential).

     2.11.  Funding Loss Indemnification.  If Borrower shall (a) repay, prepay 
            ----------------------------
or convert any LIBOR Loan on any day other than the last day of an Interest
Period therefor (whether a scheduled payment, an optional prepayment or
conversion, a mandatory prepayment or conversion, a payment upon acceleration or
otherwise), (b) fail to borrow any LIBOR Loan for which a Notice of Borrowing
has been delivered to Agent (whether as a result of the failure to satisfy any
applicable conditions or otherwise) or (c) fail to convert any Loans into LIBOR
Loans in accordance with a Notice of Conversion delivered to Agent (whether as a
result of the failure to satisfy any applicable conditions or otherwise),
Borrower shall, upon demand by any Lender, reimburse such Lender for and hold
such Lender harmless from all costs and losses incurred by such Lender as a
result of such repayment, prepayment, conversion or failure. Borrower
understands that

                                      33
<PAGE>
 
such costs and losses may include, without limitation, losses incurred by a
Lender as a result of funding and other contracts entered into by such Lender to
fund a LIBOR Loan. Each Lender demanding payment under this Paragraph 2.11 shall
                                                            --------------
deliver to Borrower, with a copy to Agent, a certificate setting forth the
amount of costs and losses for which demand is made, which certificate shall set
forth in reasonable detail the calculation of the amount demanded. Such a
certificate so delivered to Borrower shall constitute prima facie evidence of
such costs and losses. The obligations of Borrower under this Paragraph 2.11
                                                              --------------
shall survive the payment and performance of the Obligations and the termination
of this Agreement.

            (b)  Further Assurances.  Borrower shall deliver, or cause its 
                 ------------------
Subsidiaries to deliver, to Agent such additional mortgages, deeds of trust,
security agreements, pledge agreements, guaranties, lessor consents and
estoppels (containing appropriate mortgagee and lender protection language) and

                 (i)   Grant, perfect, maintain, protect and evidence security 
            interests in favor of Agent, for the benefit of Agent and the

     reasonable costs and expenses incurred by Agent in realizing such proceeds.

                (ii)    If any proceeds then remain, Agent shall apply such

            (k)  No Agreements to Sell Assets; Etc.  Neither Borrower nor any 
                 ---------------------------------
     of its Subsidiaries has any legal obligation, absolute or contingent, to
     any Person to sell the assets of Borrower or any of its Subsidiaries (other
     than sales in the ordinary course of business), or to effect any merger,
     consolidation or other reorganization of Borrower or any of its
     Subsidiaries or to enter into any agreement with respect thereto.

            (l)  Employee Benefit Plans.
                 ----------------------

                 (i)    Based on the latest valuation of each Employee Benefit 
           Plan that either Borrower or any ERISA Affiliate maintains or
           contributes to, or has any obligation under (which occurred within
           twelve months of the date of this representation), the aggregate
           benefit liabilities of such plan within the meaning of (S) 4001 of
           ERISA did not exceed the aggregate value of the assets of such plan.
           Neither Borrower nor any ERISA Affiliate has any liability with
           respect to any post-retirement benefit under any Employee Benefit
           Plan

                                      39
<PAGE>
 
           which is a welfare plan (as defined in section 3(1) of ERISA), other
           than liability for health plan continuation coverage described in
           Part 6 of Title I(B) of ERISA, which liability for health plan
           contribution coverage is not reasonably likely to have a Material
           Adverse Effect.

                 (ii)   Each Employee Benefit Plan complies, in both form and 
           operation, in all material respects, with its terms, ERISA and the
           IRC, and no condition exists or event has occurred with respect to
           any such plan which would result in the incurrence by either Borrower
           or any ERISA Affiliate of any material liability, fine or penalty.
           Each Employee Benefit Plan, related trust agreement, arrangement and
           commitment of Borrower or any ERISA Affiliate is legally valid and
           binding and in full force and effect. No Employee Benefit Plan is
           being audited or investigated by any government agency or is subject
           to any pending or threatened claim or suit. Neither Borrower nor any
           ERISA Affiliate nor any fiduciary of any Employee Benefit Plan has
           engaged in a prohibited transaction under section 406 of ERISA or
           section 4975 of the IRC.

                 (iii)  Neither Borrower nor any ERISA Affiliate contributes 
           to or has any material contingent obligations to any Multiemployer
           Plan. Neither Borrower nor any ERISA Affiliate has incurred any
           material liability (including secondary liability) to any
           Multiemployer Plan as a result of a complete or partial withdrawal
           from such Multiemployer Plan under Section 4201 of ERISA or as a
           result of a sale of assets described in Section 4204 of ERISA.
           Neither Borrower nor any ERISA Affiliate has been notified that any
           Multiemployer Plan is in reorganization or insolvent under and within
           the meaning of Section 4241 or Section 4245 of ERISA or that any
           Multiemployer Plan intends to terminate or has been terminated under
           Section 4041A of ERISA.

            (m)  Other Regulations.  Borrower is not subject to regulation 
                 -----------------
     under the Investment Company Act of 1940, the Public Utility Holding
     Company Act of 1935, the Federal Power Act, the Interstate Commerce Act,
     any state public utilities code or to any other Governmental Rule limiting
     its ability to incur indebtedness.

            (n)  Patent and Other Rights.  Borrower and its Subsidiaries own 
                 -----------------------
     or license under validly existing agreements, and have the full right to
     license without the consent of any other Person, all patents, licenses,
     trademarks, trade names, trade secrets, service marks, copyrights and all
     rights with respect thereto, which are required to conduct their businesses
     as now conducted.

                 --------------------
     filed or caused to be filed all tax returns which are required to be filed
     by them. Borrower and its Subsidiaries have paid, or made provision for the
     payment of, all taxes and other Governmental Charges which have or may have
     become due pursuant to said returns or otherwise and all other
     indebtedness, except such Governmental Charges or indebtedness, if any,
     which are being contested in good faith and as to which adequate reserves
     (determined in accordance with GAAP) have been provided or which are not
     reasonably likely to have a Material Adverse Effect if unpaid.

            (p)  Margin Stock.  Borrower owns no Margin Stock which, in the 
                 ------------
     aggregate, would constitute a substantial part of the assets of Borrower,
     and no proceeds of any Loan will be used to purchase or carry, directly or
     indirectly, any Margin Stock or to extend credit, directly or indirectly,
     to any Person for the purpose of purchasing or carrying any Margin Stock.

            (q)  Subsidiaries, etc.  Set forth in Schedule 4.01(q) (as 
                 -----------------                ----------------
     supplemented by Borrower from time to time in a written notice to Agent) is
     a complete list of all of Borrower's Subsidiaries, the jurisdiction of
     incorporation of each, the classes of Equity Securities of each and the
     number of shares and percentages of shares of each such class owned
     directly or indirectly by Borrower. Except for such Subsidiaries, Borrower
     has no Subsidiaries, is not a partner in any partnership or a joint
     venturer in any joint venture.

            (r)  Catastrophic Events.  Neither Borrower nor any of its 
                 -------------------
     Subsidiaries and none of their properties is or has been affected by any
     fire, explosion, accident, strike, lockout or other labor dispute, drought,
     storm, hail, earthquake, embargo, act of God or other casualty that is
     reasonably likely to have a Material Adverse Effect. There are no disputes
     presently subject to grievance procedure, arbitration or litigation under
     any of the collective bargaining agreements, employment contracts or
     employee welfare or incentive plans to which Borrower or any of its
     Subsidiaries is a party, and there are no strikes, lockouts, work stoppages
     or slowdowns, or, to the best knowledge of Borrower, jurisdictional
     disputes or organizing activities occurring or threatened which alone or in
     the aggregate are reasonably likely to have a Material Adverse Effect.

            (s)  Burdensome Contractual Obligations, Etc.  Neither Borrower 
                 ---------------------------------------
     nor any of its Subsidiaries and none of their properties is subject to any
     Contractual Obligation or Requirement of Law which is reasonably likely to
     have a Material Adverse Effect.

            (t)  No Material Adverse Effect.  No event has occurred and no 
                 --------------------------
     condition exists which is reasonably likely to have a Material Adverse
     Effect.

            (v)  Accuracy of Information Furnished.  None of the Credit 
                 ---------------------------------
     Documents and none of the other certificates, statements or information

     Subsidiaries in connection with the Credit Documents or the transactions
     contemplated thereby contains or will contain any untrue statement of a
     material fact or omits or will omit to state a material fact necessary to
     make the statements therein, in light of the circumstances under which they
     were made, not misleading.

     4.02.       Reaffirmation. Borrower shall be deemed to have reaffirmed, for
                 -------------
the benefit of the Lenders and Agent, each representation and warranty contained

SECTION VII.    THE AGENT AND RELATIONS AMONG LENDERS.
                -------------------------------------

     7.01.      Appointment, Powers and Immunities. Each Lender hereby appoints
                ----------------------------------
and authorizes Agent to act as its agent hereunder and under the other Credit
Documents with such powers as are expressly delegated to Agent by the terms of
this Agreement and the other Credit Documents, together with such other powers
as are reasonably incidental thereto. Agent shall not have any duties or
responsibilities except those expressly set forth in this Agreement or in any
other Credit Document, be a trustee for any Lender or have any fiduciary duty to
any Lender. Notwithstanding anything to the contrary contained herein Agent
shall not be required to take any action which is contrary to this Agreement or
any other Credit Document or any applicable Governmental Rule. Neither Agent nor
any Lender shall be responsible to any other Lender for any recitals,
statements, representations or warranties made by Borrower or any of its

                                      56
<PAGE>
 
Subsidiaries contained in this Agreement or in any other Credit Document, for
the value, validity, effectiveness, genuineness, enforceability or sufficiency
of this Agreement or any other Credit Document or for any failure by Borrower or
any of its Subsidiaries to perform their respective obligations hereunder or
thereunder. Agent may employ agents and attorneys-in-fact and shall not be
responsible to any Lender for the negligence or misconduct of any such agents or
attorneys-in-fact selected by it with reasonable care. Neither Agent nor any of
its directors, officers, employees, agents or advisors shall be responsible to
any Lender for any action taken or omitted to be taken by it or them hereunder
or under any other Credit Document or in connection herewith or therewith,
except for its or their own gross negligence or willful misconduct. Except as
otherwise provided under this Agreement, Agent shall take such action with
respect to the Credit Documents as shall be directed by the Required Lenders.

     7.02.   Reliance by Agent.  Agent shall be entitled to rely upon any 
             -----------------
certificate, notice or other document (including any cable, telegram, facsimile
or telex) believed by it in good faith to be genuine and correct and to have
been signed or sent by or on behalf of the proper Person or Persons, and upon
advice and statements of legal counsel, independent accountants and other
experts selected by Agent with reasonable care. As to any other matters not
expressly provided for by this Agreement, Agent shall not be required to take
any action or exercise any discretion, but shall be required to act or to
refrain from acting upon instructions of the Required Lenders and shall in all
cases be fully protected by the Lenders in acting, or in refraining from acting,
hereunder or under any other Credit Document in accordance with the instructions
of the Required Lenders, and such instructions of the Required Lenders and any
action taken or failure to act pursuant thereto shall be binding on all of the
Lenders.

     7.03.  Defaults.  Agent shall not be deemed to have knowledge or notice 
            --------
of the occurrence of any Default or Event of Default unless Agent has received a
written notice from a Lender or Borrower, referring to this Agreement,
describing such Default or Event of Default and stating that such notice is a
"Notice of Default". If Agent receives such a notice of the occurrence of a
Default or Event of Default, Agent shall give prompt notice thereof to the
Lenders. Agent shall take such action with respect to such Default or Event of
Default as shall be reasonably directed by the Required Lenders; provided,
                                                                 --------
however, that until Agent shall have received such directions, Agent may (but
- -------
shall not be obligated to) take such action, or refrain from taking such action,
with respect to such Default or Event of Default as it shall deem advisable in
the best interest of the Lenders.

     7.04.  Indemnification.  Without limiting the Obligations of Borrower 
            ---------------
hereunder, each Lender agrees to indemnify Agent, ratably in accordance with
their Proportionate Shares, for any

                                      57
<PAGE>
 
and all liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements of any kind or nature
whatsoever which may at any time be imposed on, incurred by or asserted against
Agent in any way relating to or arising out of this Agreement or any documents
contemplated by or referred to herein or therein or the transactions
contemplated hereby or thereby or the enforcement of any of the terms hereof or
thereof; provided, however, that no Lender shall be liable for any of the
         --------  -------
foregoing to the extent they arise from Agent's gross negligence or willful
misconduct. Agent shall be fully justified in refusing to take or in continuing
to take any action hereunder unless 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
obligations of each Lender under this Paragraph 7.04 shall survive the payment
                                      --------------
and performance of the Obligations, the termination of this Agreement and any
Lender ceasing to be a party to this Agreement (with respect to events which
occurred prior to the time such Lender ceased to be a Lender hereunder).

     7.05.  Non-Reliance.  Each Lender represents that it has, independently 
            ------------
and without reliance on Agent, or any other Lender, and based on such documents
and information as it has deemed appropriate, made its own appraisal of the
business, prospects, management, financial condition and affairs of Borrower and
the Subsidiaries and its own decision to enter into this Agreement and agrees
that it will, independently and without reliance upon Agent or any other Lender,
and based on such documents and information as it shall deem appropriate at the
time, continue to make its own appraisals and decisions in taking or not taking
action under this Agreement. Neither Agent nor any of its affiliates nor any of
their respective directors, officers, employees, agents or advisors shall (a) be
required to keep any Lender informed as to the performance or observance by
Borrower or any of its Subsidiaries of the obligations under this Agreement or
any other document referred to or provided for herein or to make inquiry of, or
to inspect the properties or books of Borrower or any of its Subsidiaries; (b)
have any duty or responsibility to provide any Lender with any credit or other
information concerning Borrower or any of its Subsidiaries which may come into
the possession of Agent, except for notices, reports and other documents and
information expressly required to be furnished to the Lenders by Agent
hereunder; or (c) be responsible to any Lender for (i) any recital, statement,
representation or warranty made by Borrower or any officer, employee or agent of
Borrower in this Agreement or in any of the other Credit Documents, (ii) the
value, validity, effectiveness, genuineness, enforceability or sufficiency of
this Agreement or any Credit Document, (iii) the value or sufficiency of the
Collateral or the validity or perfection of any of the liens or security
interests intended to be created by the Credit Documents, or (iv) any failure by
Borrower to perform its obligations under this Agreement or any other Credit
Document.

                                      58
<PAGE>
 
     7.06.  Resignation or Removal of Agent.  Agent may resign at any time by 
            -------------------------------
giving thirty (30) days prior written notice thereof to Borrower and the
Lenders, and Agent may be removed at any time with or without cause by the
Required Lenders. Upon any such resignation or removal, the Required Lenders
shall have the right to appoint a successor Agent, which Agent, if not a Lender,
shall be reasonably acceptable to Borrower; provided, however, that Borrower
                                            -----------------
shall have no right to approve a successor Agent if a Default or an Event of
Default has occurred and is continuing. Upon the acceptance of any appointment
as Agent hereunder by a successor Agent, such successor Agent shall thereupon
succeed to and become vested with all the rights, powers, privileges and duties
of the retiring Agent, and the retiring Agent shall be discharged from the
duties and obligations thereafter arising hereunder. After any retiring Agent's
resignation or removal hereunder as Agent, the provisions of this Section VII
                                                                  -----------
shall continue in effect for its benefit in respect of any actions taken or
omitted to be taken by it while it was acting as Agent.

     7.07.  Authorization.  Agent is hereby authorized by the Lenders to 
            -------------
execute, deliver and perform, each of the Credit Documents to which Agent is or
is intended to be a party and each Lender agrees to be bound by all of the
agreements of Agent contained in the Credit Documents.

     7.08.  Agent in its Individual Capacity.  Agent and its affiliates may 
            --------------------------------
make loans to, accept deposits from and generally engage in any kind of banking
or other business with Borrower and its Subsidiaries and affiliates as though
Agent were not Agent hereunder. With respect to Loans, if any, made by Agent in
its capacity as a Lender, Agent in its capacity as a Lender shall have the same
rights and powers under this Agreement and the other Credit Documents as any
other Lender and may exercise the same as though it were not Agent, and the
terms "Lender" or "Lenders" shall include Agent in its capacity as a Lender.

Each Notice of Borrowing, Notice of Conversion and Notice of Interest Period
Selection shall be given by Borrower to Agent's office located at the address
referred to above during Agent's normal business hours; provided, however, that
                                                        --------  -------
any such notice received by Agent after 10:30 a.m. on any Business Day shall be
deemed received by Agent on the next Business Day.  In any case where this
Agreement authorizes notices, requests, demands or other communications by
Borrower to Agent or any Lender to be made by telephone or facsimile, Agent or
any Lender may conclusively presume that anyone purporting to be a person
designated in any incumbency certificate or other similar document received by
Agent or a Lender is such a person.

     8.02.  Expenses.  Borrower shall pay on demand, whether or not any
            --------
Loan is made hereunder, (a) all reasonable fees and expenses, including
reasonable attorneys' fees and expenses, incurred by Agent in connection with
the preparation, negotiation, execution and delivery of, and the exercise of its
duties under, this Agreement and the other Credit Documents, and the
preparation, negotiation, execution and delivery of amendments and waivers
hereunder and thereunder and (b) all reasonable fees and expenses, including
reasonable attorneys' fees and expenses, incurred by Agent and the Lenders in
the enforcement or attempted enforcement of any of the Obligations or in
preserving any of Agent's or the Lenders' rights and remedies (including,
without limitation, all such fees and expenses incurred in connection with any
"workout" or restructuring affecting the Credit Documents or the Obligations or
any 

                                      60
<PAGE>
 
bankruptcy or similar proceeding involving Borrower or any of its
Subsidiaries).  As used herein, the term "reasonable attorneys' fees and
expenses" shall include, without limitation, allocable costs and expenses of
Agent's and Lenders' in-house legal counsel and staff.  The obligations of
Borrower under this Paragraph 8.02 shall survive the payment and performance of
                    --------------
the Obligations and the termination of this Agreement.

     8.03. Indemnification.  To the fullest extent permitted by law, Borrower
           ---------------
agrees to protect, indemnify, defend and hold harmless Agent, the Lenders and
their Affiliates and their respective directors, officers, employees, agents and
advisors ("Indemnitees") from and against any and all liabilities, losses,
           -----------
damages or expenses of any kind or nature and from any suits, claims or demands
(including in respect of or for reasonable attorney's fees and other expenses)
arising on account of or in connection with any matter or thing or action or
failure to act by Indemnitees, or any of them, arising out of or relating to the
Credit Documents or any transaction contemplated thereby, including without
limitation any use by Borrower of any proceeds of the Loans, except to the
extent such liability arises from the willful misconduct or gross negligence of
such Indemnitee. Upon receiving knowledge of any suit, claim or demand asserted
by a third party that Agent or any Lender believes is covered by this indemnity,
Agent or such Lender shall give Borrower notice of the matter and an opportunity
to defend it, at Borrower's sole cost and expense, with legal counsel
satisfactory to Agent or such Lender, as the case may be. Agent or such Lender
may also require Borrower to defend the matter. Any failure or delay of Agent or
any Lender to notify Borrower of any such suit, claim or demand shall not
relieve Borrower of its obligations under this Paragraph 8.03 but shall reduce
                                               --------------
such obligations to the extent of any increase in those obligations caused
solely by any such failure or delay which is unreasonable. The obligations of
Borrower under this Paragraph 8.03 shall survive the payment and performance of
                    --------------
the Obligations and the termination of this Agreement.

     8.04. Waivers; Amendments.  Any term, covenant, agreement or condition of
           -------------------
this Agreement or any other Credit Document may be amended or waived, and any
consent under this Agreement or any other Credit Document may be given, if such
amendment, waiver or consent is in writing and is signed by Borrower and the
Required Lenders (or Agent on behalf of the Required Lenders with the written
approval of the Required Lenders); provided, however that:
                                   --------  -------

           (a)  Any amendment, waiver or consent which would (i) increase the 
     Total Commitment, (ii) extend the Maturity Date, (iii) reduce the principal
     of or interest on any Loan or any fees or other amounts payable for the
     account of the Lenders hereunder, (iv) extend any scheduled principal,
     interest or fee payment date, (v) amend this Paragraph 8.04, (vi) amend the
                                                  --------------
     definition of Required Lenders or (vii) 

                                      61
<PAGE>
 
     release any substantial part of the Collateral, must be in writing and
     signed or approved in writing by all Lenders;

           (b)  Any amendment, waiver or consent which increases or decreases 
     the Proportionate Share of any Lender must be in writing and signed by such
     Lender; and

           (c)  Any amendment, waiver or consent which affects the rights or 
     obligations of Agent must be in writing and signed by Agent.

No failure or delay by Agent or any Lender in exercising any right under this
Agreement or any other Credit Document shall operate as a waiver thereof or of
any other right hereunder or thereunder nor shall any single or partial exercise
of any such right preclude any other further exercise thereof or of any other
right hereunder or thereunder.  Unless otherwise specified in such waiver or
consent, a waiver or consent given hereunder shall be effective only in the
specific instance and for the specific purpose for which given.

     8.05.  Successors and Assigns.
            ----------------------

            (a)  Binding Effect.  This Agreement and the other Credit Documents 
                 --------------
     shall be binding upon and inure to the benefit of Borrower, the Lenders,
     Agent, all future holders of the Notes and their respective successors and
     permitted assigns, except that Borrower may not assign or transfer any of
     its rights or obligations under any Credit Document without the prior
     written consent of Agent and each Lender. All references in this Agreement
     to any Person shall be deemed to include all successors and assigns of such
     Person.

            (b)  Participations.  Any Lender may at any time sell to one or 
                 --------------
     more banks or other financial institutions ("Participants") participating
                                                  ------------
     interests in any Loan owing to such Lender, any Note held by such Lender,
     any Commitment of such Lender or any other interest of such Lender under
     this Agreement and the other Credit Documents. In the event of any such
     sale by a Lender of participating interests, such Lender's obligations
     under this Agreement shall remain unchanged, such Lender shall remain
     solely responsible for the performance thereof, such Lender shall remain
     the holder of its Notes for all purposes under this Agreement and Borrower
     and Agent shall continue to deal solely and directly with such Lender in
     connection with such Lender's rights and obligations under this Agreement.
     Any agreement pursuant to which any such sale is effected may require the
     selling Lender to obtain the consent of the Participant in order for such
     Lender to agree in writing to any amendment, waiver or consent of a type
     specified in clause (i), (ii), (iii) or (iv) of Subparagraph 8.04(a) but
                  -------------------------------------------------------
     may not otherwise require the selling Lender to obtain the consent of such
     Participant to any other amendment, waiver or consent hereunder. Borrower
     also agrees that any Lender which has 

                                      62
<PAGE>
 
     transferred any participating interest in its Commitment or Loans shall,
     notwithstanding any such transfer, be entitled to the full benefits
     accorded such Lender under Paragraph 2.09, Paragraph 2.10, and Paragraph
                                --------------  --------------      ---------
     2.11, as if such Lender had not made such transfer.
     ----

            (c)  Assignments.  Any Lender may, at any time, sell and assign to 
                 -----------
     any Lender or any Eligible Assignee (individually, an "Assignee Lender")
                                                            ---------------
     all or a portion of its rights and obligations under this Agreement and the
     other Credit Documents (such a sale and assignment to be referred to herein
     as an "Assignment") pursuant to an assignment agreement in the form of
            ----------
     Exhibit J (an "Assignment Agreement"), executed by each Assignee Lender and
     ---------      --------------------
     such assignor Lender (an "Assignor Lender") and delivered to Agent for its
                               ---------------
     acceptance and recording in the Register; provided, however, that:
                                               --------  -------
                 (i)    Without the written consent of Agent and, if no 
           Default or Event of Default has occurred and is continuing, Borrower
           (which consent of Agent and Borrower shall not be unreasonably
           withheld), no Lender may make any Assignment to any Assignee Lender
           which is not, immediately prior to such Assignment, a Lender
           hereunder or an Affiliate thereof; or

                 (ii)   Without the written consent of Agent and, if no Default 
           or Event of Default has occurred and is continuing, Borrower (which
           consent of Agent and Borrower shall not be unreasonably withheld), no
           Lender may make any Assignment to any Assignee Lender if, after
           giving effect to such Assignment, the Commitment of such Lender or
           such Assignee Lender would be less than Five Million Dollars
           ($5,000,000) (except that a Lender may make an Assignment which
           reduces its Commitment to zero without the written consent of
           Borrower and Agent); or

                 (iii)  Without the written consent of Agent and, if no Default 
           or Event of Default has occurred and is continuing, Borrower (which
           consent of Agent and Borrower shall not be unreasonably withheld), no
           Lender may make any Assignment which does not assign and delegate an
           equal pro rata interest in such Lender's Loans, Commitment and all
           other rights, duties and obligations of such Lender under this
           Agreement and the other Credit Documents.

     Upon such execution, delivery, acceptance and recording of each Assignment
     Agreement, from and after the Assignment Effective Date determined pursuant
     to such Assignment Agreement, (A) each Assignee Lender thereunder shall be
     a Lender hereunder with a Proportionate Share as set forth on Attachment 1
                                                                   ------------
     to such Assignment Agreement (under the caption "Proportionate Share After
     ----------------------------
     Assignment") and shall have the 

                                      63
<PAGE>
 
     rights, duties and obligations of such a Lender under this Agreement and
     the other Credit Documents, and (B) the Assignor Lender thereunder shall be
     a Lender with a Proportionate Share as set forth on Attachment 1 to such
                                                         --------------------
     Assignment Agreement (under the caption "Proportionate Share After
     --------------------
     Assignment"), or, if the Proportionate Share of the Assignor Lender has
     been reduced to 0%, the Assignor Lender shall cease to be a Lender and to
     have any obligation to make any Loan; provided, however, that any such
                                           --------  -------
     Assignor Lender which ceases to be a Lender shall continue to be entitled
     to the benefits of any provision of this Agreement which by its terms
     survives the termination of this Agreement. Each Assignment Agreement shall
     be deemed to amend Schedule I to the extent, and only to the extent,
                        ----------
     necessary to reflect the addition of each Assignee Lender, the deletion of
     each Assignor Lender which reduces its Proportionate Share to 0% and the
     resulting adjustment of Proportionate Shares arising from the purchase by
     each Assignee Lender of all or a portion of the rights and obligations of
     an Assignor Lender under this Agreement and the other Credit Documents. On
     or prior to the Assignment Effective Date determined pursuant to each
     Assignment Agreement, Borrower, at its own expense, shall execute and
     deliver to Agent, in exchange for the surrendered Note of the Assignor
     Lender thereunder, a new Note to the order of each Assignee Lender
     thereunder (with each new Note to be in an amount equal to the Commitment
     assumed by such Assignee Lender) and, if the Assignor Lender is continuing
     as a Lender hereunder, a new Note to the order of the Assignor Lender (with
     the new Note to be in an amount equal to the Commitment retained by it).
     Each such new Note shall be dated the Closing Date and each shall otherwise
     be in the form of the Note replaced thereby. The Notes surrendered by the
     Assignor Lender shall be returned by Agent to Borrower marked "replaced".
     Each Assignee Lender which was not previously a Lender hereunder and which
     is not incorporated under the laws of the United States of America or a
     state thereof shall, within three (3) Business Days of becoming a Lender,
     deliver to Borrower and Agent two duly completed copies of United States
     Internal Revenue Service Form 1001 or 4224 (or successor applicable form),
     as the case may be, certifying in each case that such Lender is entitled to
     receive payments under this Agreement without deduction or withholding of
     any United States federal income taxes.

            (d)  Register.  Agent shall maintain at its address referred to in 
                 --------
     Paragraph 8.01 a copy of each Assignment Agreement delivered to it and a
     --------------
     register (the "Register") for the recordation of the names and addresses of
                    --------
     the Lenders and the Proportionate Shares of each Lender from time to time.
     The entries in the Register shall be conclusive in the absence of manifest
     error, and Borrower, Agent and the Lenders may treat each Person whose name
     is recorded in the Register as the owner of the Loans recorded therein for
     all purposes of this Agreement. The Register 

                                      64
<PAGE>
 
     shall be available for inspection by Borrower or any Lender at any
     reasonable time and from time to time upon reasonable prior notice.

            (e)  Registration.  Upon its receipt of an Assignment Agreement 
                 ------------
     executed by an Assignor Lender and an Assignee Lender (and, to the extent
     required by Subparagraph 8.05(c), by Borrower and Agent) together with
                 --------------------
     payment to Agent by Assignor Lender of a registration and processing fee of
     $2,500, Agent shall (i) promptly accept such Assignment Agreement and 
     (ii) on the Effective Date determined pursuant thereto record the
     information contained therein in the Register and give notice of such
     acceptance and recordation to the Lenders and Borrower. Agent may, from
     time to time at its election, prepare and deliver to the Lenders and
     Borrower a revised Schedule I reflecting the names, addresses and
                        ----------
     respective Proportionate Shares of all Lenders then parties hereto.

            (f)  Confidentiality.  Agent and the Lenders may disclose the 
                 ---------------
     Credit Documents and any financial or other information relating to
     Borrower or any Subsidiary to each other or, with the consent of Borrower,
     to any potential Participant or Assignee Lender.

     8.06.  Setoff; Security Interest.
            -------------------------

            (a)  Setoff.  In addition to any rights and remedies of the Lenders 
                 ------
     provided by law, each Lender shall have the right, with the prior consent
     of Agent but without prior notice to or consent of Borrower, any such
     notice and consent being expressly waived by Borrower to the extent
     permitted by applicable law, upon the occurrence and during the continuance
     of an Event of Default, to set-off and apply against the Obligations any
     amount owing from such Lender to Borrower. The aforesaid right of set-off
     may be exercised by such Lender against Borrower or against any trustee in
     bankruptcy, debtor in possession, assignee for the benefit of creditors,
     receiver or execution, judgment or attachment creditor of Borrower or
     against anyone else claiming through or against Borrower or such trustee in
     bankruptcy, debtor in possession, assignee for the benefit of creditors,
     receiver, or execution, judgment or attachment creditor, notwithstanding
     the fact that such right of set-off may not have been exercised by such
     Lender at any prior time. Each Lender agrees promptly to notify Borrower
     after any such set-off and application made by such Lender, provided that
                                                                 --------
     the failure to give such notice shall not affect the validity of such set-
     off and application.

            (b)  Security Interest.  As security for the Obligations, Borrower 
                 -----------------
     hereby grants to Agent and each Lender, for the benefit of all Lenders, a
     continuing security interest in any and all deposit accounts or moneys of
     Borrower now or hereafter maintained with such Lender. 

                                      65
<PAGE>
 
     Each Lender shall have all of the rights of a secured party with respect to
     such security interest.

     8.07. No Third Party Rights.  Nothing expressed in or to be implied from
           ---------------------
this Agreement is intended to give, or shall be construed to give, any Person,
other than the parties hereto and their permitted successors and assigns
hereunder, any benefit or legal or equitable right, remedy or claim under or by
virtue of this Agreement or under or by virtue of any provision herein.

     8.08.  Partial Invalidity.  If at any time any provision of this Agreement 
            ------------------
is or becomes illegal, invalid or unenforceable in any respect under the law or
any jurisdiction, neither the legality, validity or enforceability of the
remaining provisions of this Agreement nor the legality, validity or
enforceability of such provision under the law of any other jurisdiction shall
in any way be affected or impaired thereby.

     8.09.  Jury Trial.  EACH OF BORROWER, THE LENDERS AND AGENT, TO THE FULLEST
            ----------
EXTENT PERMITTED BY APPLICABLE LAW, HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL
BY JURY AS TO ANY ISSUE RELATING HERETO IN ANY ACTION, PROCEEDING, OR
COUNTERCLAIM ARISING OUT OF OR RELATING TO ANY CREDIT DOCUMENT.

     8.10. Counterparts.  This Agreement may be executed in any number of
           ------------
identical counterparts, any set of which signed by all the parties hereto shall
be deemed to constitute a complete, executed original for all purposes.

     8.11. Confidentiality. None of the Banks and Agent shall disclose to any
           ---------------
Person any information with respect to Borrower or any of its Subsidiaries which
is furnished pursuant to this Agreement or under the other Credit Documents,
except that any Bank or Agent may disclose any such information (a) to its own
directors, officers, employees, auditors, counsel and other professional
advisors and to its Affiliates if such Bank or Agent or such Bank's or such
Agent's holding or parent company in its sole discretion determines that any
such party should have access to such information; (b) to another Bank or Agent;
(c) if generally available to the public through no fault of Agent or the Banks;
(d) if required or appropriate in any report, statement or testimony submitted
to any Governmental Authority having or claiming to have jurisdiction over such
Bank or Agent; (e) if required or appropriate in response to any summons or
subpoena or in connection with any litigation, to the extent permitted or deemed
advisable by counsel; (f) to comply with any Requirement of Law applicable to
such Bank or Agent; (g) to any Participant or Assignee Bank or any prospective
Participant or Assignee Bank, provided that such Participant or Assignee or
prospective Participant or Assignee agrees in writing to be bound by this
Paragraph 8.11 prior to disclosure; or (h) otherwise with the prior consent of
- --------------
Borrower; provided, however, that any disclosure made in violation of this
          --------  -------
Agreement shall not affect the obligations of Borrower and its Subsidiaries
under this Agreement and the other Credit Documents.

                                      66

     8.12. Termination of Prior Credit Agreements. Borrower, ABN and Sanwa agree
           --------------------------------------
that, on and after the Closing Date, all obligations of ABN and Sanwa to make
loans, issue letters of credit or otherwise extend credit to Borrower under the
Prior Credit Agreements shall be terminated; provided, however, that such
                                             --------  -------
termination shall not (a) operate as a waiver of any right, power or remedy of
ABN or Sanwa under the Prior Credit Agreements or any related document,
instrument or agreement or (b) extinguish or impair any obligations of Borrower
under the Prior Credit Agreement or any related document, instrument or
agreement except to the extent any such obligation is actually satisfied by
Borrower.

1.  The Applicable Margin for each Loan and the Commitment Fee Percentage will
    be set for each quarter and will vary depending upon whether such quarter is
    a Level 1 Quarter, a Level 2 Quarter, a Level 3 Quarter, a Level 4 Quarter
    or a Level 5 Quarter.

2.  The quarter ending September 30, 1996 will be a Level 2 Quarter.

3.  Each quarter thereafter will be a Level 1 Quarter, a Level 2 Quarter, a
    Level 3 Quarter, a Level 4 Quarter or a Level 5 Quarter depending upon
    Borrower's Debt/EBITDA Ratio for the consecutive four-quarter period which
    ended with the second quarter prior to such quarter as follows:

    (a)  If, for any consecutive four-quarter period, the Borrower's Debt/EBITDA
         Ratio is less than 0.90, the second quarter after the last quarter in
         such four-quarter period will be a Level 1 Quarter.

    (b)  If, for any consecutive four-quarter period, the Borrower's Debt/EBITDA
         Ratio is equal to or greater than 0.90 but less than 1.20, the second
         quarter after the last quarter in such four-quarter period will be a
         Level 2 Quarter.

    (c)  If, for any consecutive four-quarter period, the Borrower's Debt/EBITDA
         Ratio is equal to or greater than 1.20 but less than 1.40, the second
         quarter after the last quarter in such four-quarter period will be a
         Level 3 Quarter.

                                  1.01(a) - 1
<PAGE>
 
    (d)  If, for any consecutive four-quarter period, the Borrower's Debt/EBITDA
         Ratio is equal to or greater than 1.40 but less than 1.60, the second
         quarter after the last quarter in such four-quarter period will be a
         Level 4 Quarter.

    (e)  If, for any consecutive four-quarter period, the Borrower's Debt/EBITDA
         Ratio is equal to or greater than 1.60, the second quarter after the
         last quarter in such four-quarter period will be a Level 5 Quarter.

4.  Examples:

    (a)  For the consecutive four-quarter period ending March 31, 1996, the
         Borrower's Debt/EBITDA Ratio was 1.30. The quarter ending September 30,
         1996 will again be a Level 3 Quarter.

    (b)  For the consecutive four-quarter period ending June 30, 1996, the
         Borrower's Debt/EBITDA Ratio was 1.10.  The quarter ending December 31,
         will again be a Level 2 Quarter.

the Lenders and Agent as follows:

          (a) Borrower is the legal and beneficial owner of the Collateral (or,
     in the case of after-acquired Collateral, at the time Borrower acquires
     rights in the Collateral, will be the legal and beneficial owner thereof).
     No other Person has (or, in the case of after-acquired Collateral, at the

                                      E-2

     time Borrower acquires rights therein, will have) any right, title, claim
     or interest (by way of Lien, purchase option or otherwise) in, against or
     to the Collateral, other than Permitted Liens.

          (b) Agent has (or in the case of after-acquired Collateral, at the
     time Borrower acquires rights therein, will have) a first priority
     perfected security interest in the Collateral, except for the prior Liens
     set forth in Schedule 5.02(b) to the Credit Agreement.
                  ---------------------------------------- 

          (c) All Equipment and Inventory are (i) located at the locations
     indicated in item 8 of the Collateral Certificate, (ii) in transit to such
                  ------------------------------------                         
     locations or (iii) in transit to a third party purchaser which will become
     obligated on a Receivable to Borrower upon receipt.  Except for Equipment
     and Inventory referred to in clauses (ii) and (iii) of the preceding
                                  ----------------------                 
     sentence, Borrower has exclusive possession and control of the Inventory
     and Equipment.

          (d) All Inventory has been (or, in the case of hereafter produced
     Inventory, will be) produced in compliance with all applicable Governmental
     Rules, including the Fair Labor Standards Act (if applicable).

          (e) Borrower keeps all records concerning the Receivables and the
     originals of all Related Contracts at its chief executive office located at

          (g) Each Receivable is genuine and enforceable against the party
     obligated to pay the same (an "Account Debtor") free from any right of

     rescission, defense, setoff or discount.

          (h) Each insurance policy maintained by Borrower is validly existing
     and is in full force and effect.  Borrower is not in default in any
     material respect under the provisions of any insurance policy, and there
     are no facts which, with the giving of notice or passage of time (or both),
     would result in such a default under any provision of any such insurance
     policy.

          (i) The information set forth in the Collateral Certificate is true,
                                           --------------------------

for failure so to do) any act which Borrower is obligated by this Security
Agreement to perform, and to exercise such rights and powers as Borrower might
exercise with respect to the Collateral, including, without limitation, the
right to (a) collect by legal proceedings or otherwise and endorse, receive and
receipt for all dividends, interest, payments, proceeds and other sums and

to reimburse Agent upon demand for all reasonable costs and expenses, including
attorneys' fees, Agent may incur while acting as Borrower's attorney-in-fact
hereunder, all of which costs and expenses are included in the Secured

Default, as that term is defined in the Credit Agreement.  In addition to all

Governmental Rules, Agent may, upon the occurrence and during the continuance of
any Event of Default, exercise any one or more of the following rights and

grants to Agent an irrevocable, non-exclusive license (exercisable without
royalty or other payment by Agent) to use, license or sublicense any patent,
trademark, tradename, copyright or other intellectual property in which Borrower
now or hereafter has any right, title or interest, together with the right of

     other further exercise thereof or of any other right.  Unless otherwise
     specified in any such

     Collateral or to pursue any remedy in Agent's or such Lender's power.

          (f) Payments Free of Taxes, Etc.  All payments made by Borrower under

the Lenders and Agent as follows:

          (a) Borrower is the legal and beneficial owner of the Collateral (or,
     in the case of after-acquired Collateral, at the time Borrower acquires
     rights in the Collateral, will be the beneficial owner thereof).  No other
     Person has (or, in the case of after-acquired Collateral, at the time
     Borrower acquires rights therein, will have) any right, title, claim or
     interest (by way of Lien, purchase option or otherwise) in, against or to
     the Collateral, other than Permitted Liens.

          (b) Agent has (or in the case of after-acquired Collateral, at the
     time Borrower acquires rights therein, will have) a first priority
     perfected security interest in the Collateral, subject to Permitted Liens;
                                                                               
     provided, however, that (i) the security interest of Agent may be subject
     --------  -------                                                        
     to Permitted Liens and (ii) Agent must make the filings with the Patent and
     Trademark Office contemplated by this Security Agreement to perfect its
     security interest in Borrower's Patents and Trademarks registered with that
     office.

          (c) Borrower has the sole, full and unencumbered right, title and
     interest in and to (i) each of the Trademarks described in Schedule A to
                                                                -------------
     Attachment 1 hereto for the goods and services covered by the registrations
     ------------                                                               
     thereof, (ii) each of the Patents described in Schedule B to Attachment 1
                                                    --------------------------
     hereto, (iii) each of the Copyrights described in Schedule C to Attachment
                                                       ------------------------
     1 hereto and (iv) each of the Mask Works described in Schedule D to
     -                                                     -------------
     Attachment 1 hereto.  The registrations for such Trademarks and Patents are
     ------------                                                               
     valid and enforceable and in full force and effect and none of the Patents
     has been abandoned or dedicated.  According to the records of the Copyright
     Office, such Copyrights and Mask Works are valid and enforceable and in
     full force and effect.

          (d) Borrower does not own any Patents, Trademarks, Copyrights or Mask
     Works registered in, or the subject of pending applications in, the Patent
     and Trademark Office or the Copyright Office, other than those described in
     Schedules A, B, C and D to Attachment 1 hereto.

                                      F-3
<PAGE>
 
          (e) To the best of Borrower's knowledge, no claim has been made by any
     third party and remains unresolved that any of the Patents, Trademarks,
     Copyrights or Mask Works is invalid and unenforceable or violates or may
     violate the rights of any Person.

          (f) Borrower has obtained from each employee who may be considered the
     inventor of patentable inventions (invented within the scope of such
     employee's employment with Borrower) an agreement to assign to Borrower all
     rights to such inventions, including Patents.

          (g) Borrower has exercised reasonable prudence to protect the secrecy
     and the validity under applicable law of all material Trade Secrets.

     4.   COVENANTS OF BORROWER.  Borrower hereby agrees as follows:
          ---------------------                                     

          (a)  Borrower, at Borrower's expense, shall promptly procure, execute
     and deliver to Agent all documents, instruments and agreements and perform
     all acts which are necessary, or which Agent may reasonably request, to
     establish, maintain, preserve, protect and perfect the Collateral, the Lien
     granted to Agent therein and the first priority of such Lien or to enable
     Agent to exercise and enforce its rights and remedies hereunder with
     respect to any Collateral.  Without limiting the generality of the
     preceding sentence, Borrower shall (i) execute all notices of security
     interest for each relevant type of intellectual property in forms suitable
     for filing with the Patent and Trademark Office or the Copyright Office, as
     applicable, substantially in the forms of Attachments 2 and 3 hereto or
                                               -------------------          
     other forms acceptable to Agent and (ii) take all commercially reasonable
     steps in any proceeding before the Patent and Trademark Office, the
     Copyright Office or any similar office or agency in any other country or
     any political subdivision thereof, to diligently prosecute or maintain, as
     applicable, each application and registration of material Patents,
     Trademarks, Copyrights and Mask Works, including filing of renewals,
     affidavits of use, affidavits of incontestability and opposition,
     interference and cancellation proceedings (except to the extent that
     dedication, abandonment or invalidation is permitted hereunder or would not
     be reasonably likely to have a Material Adverse Effect).

          (b) Borrower shall not use any Collateral or permit any Collateral to
     be used in violation of (i) any provision of the Credit Agreement, this
     Security Agreement or any other Credit Document, (ii) any applicable
     Governmental Rule or Contractual Obligation where such use could reasonably
     be expected to have a Material Adverse Effect, or (iii) any policy of
     insurance covering the Collateral where such use is reasonably likely to
     have a Material Adverse Effect.

                                      F-4
<PAGE>
 
          (c) Borrower shall pay promptly when due all taxes and other
     governmental charges, all Liens and all other charges now or hereafter
     imposed upon, relating to or affecting any Collateral.

          (d) Borrower shall appear in and defend any action or proceeding which
     may affect its title to or Agent's security interest in the Collateral if
     an adverse decision is reasonably likely to have a Material Adverse Effect.

          (e) Borrower shall keep separate, accurate and complete records of the
     Collateral and shall permit Agent to examine and make copies of such
     records and provide such reports and information relating to the Collateral
     as Agent may reasonably request from time to time.

          (f) Borrower shall not surrender or lose possession of (other than to
     Agent), sell, encumber, lease, rent, option, license or otherwise dispose
     of or transfer any Collateral or right or interest therein except as
     permitted in the Credit Agreement, and Borrower shall keep the Collateral
     free of all Liens except Permitted Liens.

          (g) Borrower (either directly or through licensees) will make
     commercially reasonable efforts to continue to use the Trademarks in
     connection with each and every trademark class of goods or services
     applicable to its current line of products or services as reflected in its

     any similar office or agency in any other country or any political

     Office to register any material unpatented but patentable inventions
     developed by Borrower or its employees (within the scope of their

     judgment, deems any such Patent not to have any significant commercial
     value or determines that its rights thereunder are better preserved as a
     Trade Secret, (ii) make application to the Patent and Trademark Office to
     register any registerable but unregistered material Trademarks used by
     Borrower in connection with its products or services unless Borrower in the
     exercise of its prudent business judgment, deems any such Trademark not to
     have any significant commercial value, and (iii) make application to the
     Copyright Office to register any material unregistered Copyright or Mask
     Work to which Borrower has rights unless Borrower in the exercise of its
     prudent business judgment, deems any such Copyright or Mask Work not to

     thereunder are better protectable as a Trade Secret.

          (j) Borrower shall (i) use proper statutory notice in connection with
     its use of the Trademarks, Copyrights and Mask Works, (ii) maintain
     consistent standards of quality in its manufacture of products sold under
     the Trademarks or provision of services in connection with the Trademarks,
     and (iii) take all steps necessary to protect the secrecy and the validity
     under applicable law of all material Trade Secrets.

          (k) If any Executive Officer of Borrower learns of any use by any
     Person of any term or design likely to cause confusion with any Trademark,
     Borrower shall promptly notify Agent of such use and of all steps taken and
     to be taken to remedy any infringement of such Trademark.

          (l) Borrower shall maintain with each employee who may have access to

     employee's employment) an invention assignment agreement requiring such
     employee to assign all rights to such

          (a)  Borrower, at Borrower's expense, shall promptly procure, execute
     and deliver to Agent all documents, instruments and agreements and perform
     all acts which are necessary or desirable, or which Agent may request, to
     establish, maintain, preserve, protect and perfect the Collateral, the Lien
     granted to Agent therein and the first priority of such Lien or to enable
     Agent to exercise and enforce its rights and remedies hereunder with
     respect to any Collateral.  Without limiting the generality of the
     preceding sentence, Borrower shall (i) procure, execute and deliver to
     Agent all stock powers, endorsements, assignments, financing statements and
     other instruments of transfer requested by Agent, (ii) deliver to Agent
     promptly upon receipt the originals of all Pledged Shares, other
     certificated securities, other Collateral and all certificates, instruments
     and other writings evidencing the same and (iii) cause the Lien of Agent to
     be recorded or registered in the books of any financial intermediary or
     clearing corporation requested by Agent.

          (b) Borrower shall pay promptly when due all taxes and other
     governmental charges, all Liens and all other charges now or hereafter
     imposed upon, relating to or affecting any Collateral.

          (c) Upon demand by Agent after the occurrence and during the
     continuation of any Event of Default, Borrower shall deposit, or cause to
     be deposited, all remittances, checks and other funds (in whatever form)
     received with respect to Collateral to a deposit account for which Borrower
     has complied with subparagraph 4(e) of the Security Agreement and in which
                       -------------------------------------------             
     Agent has a first priority perfected security interest.

          (d) Borrower shall appear in and defend any action or proceeding which

          (e) Borrower shall not surrender or lose possession of (other than to
     Agent), sell, encumber, lease, rent, option, or otherwise dispose of or
     transfer any Collateral or right or interest therein except as permitted in
     the Credit Agreement, and, notwithstanding any provision of the Credit
     Agreement, Borrower shall keep the Collateral free of all Liens.

     5.  VOTING RIGHTS AND DIVIDENDS PRIOR TO DEFAULT.  Unless an Event of

Default has occurred and is continuing:

                   --------  -------                                     
     refrain from exercising any such rights where the consequence of such
     action or inaction would be (i) to impair any Collateral, the Lien granted
     to Agent therein, the first priority of such Lien or Agent's rights and
     remedies hereunder with respect to any Collateral or (ii) otherwise
     inconsistent with the terms of this Pledge Agreement and the other Credit
     Documents.

          (b) Borrower may receive and retain all dividends and interest paid in
     cash in respect of the Pledged Shares, except for any such dividends and
     interest paid in connection with a partial or total liquidation or
     dissolution or in connection with a reduction of capital, capital surplus
     or paid-in-surplus.  Borrower shall promptly deliver to Agent to hold as
     Collateral all dividends and interest which Borrower is not entitled to
     receive and retain pursuant to the preceding sentence, in the same form as
     so received (with any necessary endorsement), and, until so delivered,
     shall hold such dividends and interest in trust for the benefit of Agent,
     segregated from the other property or funds of Borrower.

     6.   AUTHORIZED ACTION BY AGENT.  Borrower hereby irrevocably appoints
          --------------------------                                       
Agent as its attorney-in-fact and agrees that Agent may perform (but Agent shall
not be obligated to and shall incur no liability to Borrower or any third party
for failure so to do) any act which Borrower is obligated by this Pledge
Agreement to perform, and to exercise such rights and powers as Borrower might
exercise with respect to the Collateral, including, without limitation, the
right to (a) collect by legal proceedings or otherwise and endorse, receive and
receipt for all dividends, interest, payments, proceeds and other sums and
property now or hereafter payable on or on account of the Collateral; (b) enter
into any extension, reorganization, deposit, merger, consolidation or other
agreement pertaining to, or deposit, surrender, accept, hold or apply other
property in exchange for the Collateral; (c) insure, process, preserve and
enforce the Collateral; (d) make any compromise or settlement, and take any
action it deems advisable, with respect to the Collateral; (e) pay any
Indebtedness of Borrower relating to the Collateral; and (f) execute UCC
financing statements and other 

                                      G-5

documents, instruments and agreements required hereunder; provided, however,
                                                          -----------------
that Agent may exercise such powers only after the occurrence and during the
continuance of an Event of Default. Borrower agrees to reimburse Agent upon
demand for all reasonable costs and expenses, including attorneys' fees, Agent
may incur while acting as Borrower's attorney-in-fact hereunder, all of which
costs and expenses are included in the Secured Obligations. Borrower agrees that
such care as Agent gives to the safekeeping of its own property of like kind
shall constitute reasonable care of the Collateral when in Agent's possession;
provided, however, that Agent shall not be required to make any presentment,
- -----------------
demand or protest, or give any notice and need not take any action to preserve
any rights against any prior party or any other Person in connection with the
Secured Obligations or with respect to the Collateral.

     7.  EVENTS OF DEFAULT.
         ----------------- 

          (a) Event of Default.  Borrower shall be deemed in default under this
              ----------------                                                 
     Pledge Agreement upon the occurrence and during the continuance of an Event
     of Default, as that term is defined in the Credit Agreement.

          (b) Voting Rights and Dividends.  Upon the occurrence and during the
              ---------------------------                                     
     continuance of an Event of Default:

               (i) All rights of Borrower to exercise the voting and other
          consensual rights which it would otherwise be entitled to exercise
          pursuant to subparagraph 5(b) hereof and to receive the dividends and
                      -----------------                                        
          interest payments which it would otherwise be authorized to receive
          and retain pursuant to subparagraph 5(a) hereof shall cease and all
                                 -----------------                           
          such rights shall thereupon become vested in Agent which shall
          thereupon have the sole right, but not the obligation, to exercise
          such voting and other consensual rights and to receive and hold as
          Collateral such dividends and interest payments.

            (ii) Borrower shall promptly deliver to Agent to hold as Collateral
          all dividends and interest received by Borrower after the occurrence
          and during the continuance of any Event of Default, in the same form
          as so received (with any necessary endorsement), and, until so
          delivered, shall hold such dividends and interest in trust for the
          benefit of Agent, segregated from the other property or funds of
          Borrower.

          (c) Other Rights and Remedies.  In addition to all other rights and
              -------------------------                                      
     remedies granted to Agent by this Pledge Agreement, the Credit Agreement,
     the other Credit Documents, the UCC and other applicable Governmental
     Rules, Agent may, upon the occurrence and during the continuance of any
     Event of Default, exercise any one or more of the following rights and
     remedies: (i) collect, receive, appropriate or realize upon the Collateral
     or otherwise foreclose or enforce 

                                      G-6
<PAGE>
 
     Agent's security interests in any or all Collateral in any manner permitted
     by applicable Governmental Rules or in this Pledge Agreement; (ii) notify
     any or all issuers of or transfer or paying agents for the Collateral or
     any applicable clearing corporation, financial intermediary or other Person
     to register the Collateral in the name of Agent or its nominee and/or to
     pay all dividends, interest and other amounts payable in respect of the
     Collateral directly to Agent; (iii) sell or otherwise dispose of any or all
     Collateral at one or more public or private sales, whether or not such
     Collateral is present at the place of sale, for cash or credit or future
     delivery, on such terms and in such manner as Agent may determine; and (iv)
     require Borrower to assemble all records and information relating to the
     Collateral and make it available to Agent at a place to be designated by
     Agent. In any case where notice of any sale or disposition of any
     Collateral is required, Borrower hereby agrees that seven (7) days notice
     of such sale or disposition is reasonable.

          (d)  Securities Laws.
               --------------- 

               (i) Borrower acknowledges and recognizes that Agent may be unable
          to effect a public sale of all or a part of the Pledged Shares and may
          be compelled to resort to one or more private sales to a restricted
          group of purchasers who will be obligated to agree, among other
          things, to acquire the Pledged Shares for their own account, for
          investment and not with a view to the distribution or resale thereof.
          Borrower acknowledges that any such private sales may be at prices and
          on terms less favorable to Agent than those of public sales, and
          agrees that such private sales shall be deemed to have been made in a
          commercially reasonable manner and that Agent has no obligation to
          delay sale of any Pledged Shares to permit the issuer thereof to
          register it for public sale under the Securities Act of 1933, as
          amended, or under any state securities law.

              (ii) Upon the occurrence of an Event of Default and at Agent's
          request, Borrower shall, and shall cause all issuers of Collateral and
          all officers and directors thereof and all other necessary Persons to,
          execute and deliver all documents, instruments and agreements and
          perform all other acts necessary or, in the opinion of Agent,
          advisable to sell the Collateral in any public or private sale,
          including any acts requested by Agent to (A) register any Collateral
          under the Securities Act of 1933, (B) qualify any Collateral under any
          state securities or "Blue Sky" laws or (C) otherwise permit any such
          sale to be made in full compliance with all applicable Governmental
          Rules.

     of this Pledge Agreement may be amended or waived only as provided in the
     Credit Agreement.  No failure or delay by Agent or any Lender in exercising

     hereunder shall be effective only in the specific instance and for the
     specific purpose for which given.

     Agreement is or becomes illegal, invalid or unenforceable in any respect
     under the law of any jurisdiction, neither the legality, validity or
     enforceability of the remaining provisions of this Pledge Agreement nor the
     legality, validity or enforceability of such provision under the law of any
     other jurisdiction shall in any way be affected or impaired thereby.

          (e) Cumulative Rights, etc.  The rights, powers and remedies of Agent
              ----------------------                                           
     and the Lenders under this Pledge Agreement shall be in addition to all
     rights, powers and remedies given to Agent and the Lenders by virtue of any
     applicable Governmental Rule, the Credit Agreement, any other Credit
     Document or any other agreement, all of which rights, powers, and remedies
     shall be cumulative and may be exercised successively or concurrently
     without impairing Agent's rights hereunder.  Borrower waives any right to
     require Agent or any Lender to proceed against any Person or to exhaust any
     Collateral or to pursue any remedy in Agent's or such Lender's power.

          (f) Payments Free of Taxes, Etc.  All payments made by Borrower under

     bodies have been obtained and made and that all requisite taxes, levies and
     charges have been paid.

          (g) Borrower's Continuing Liability.  Notwithstanding any provision of
              -------------------------------                                   
     this Pledge Agreement or any other Credit Document or any exercise by Agent
     of any of its rights hereunder or thereunder (including, without
     limitation, any right to collect or enforce any Collateral), (i) Borrower
     shall remain liable to perform its obligations and duties in connection
     with the Collateral and (ii) neither Agent nor any Lender shall assume or
     be considered to have assumed any liability to perform such obligations and
     duties or to enforce any of Borrower's rights in connection with the

              ----------------                                                
     promises to pay and perform as and when due, whether at stated maturity,
     upon acceleration or otherwise, any and all of the Guaranteed Obligations.
     If any Insolvency Proceeding relating to Borrower is commenced, each
     Guarantor further unconditionally guarantees and promises to pay and
     perform, upon the demand of Agent, any and all of the Guaranteed
     Obligations (including any and all Disallowed Post-Commencement Interest
     and Expenses) in 

                                      H-3
<PAGE>
 
     accordance with the terms of the Credit Documents, whether or not such
     obligations are then due and payable by Borrower and whether or not such
     obligations are modified, reduced or discharged in such Insolvency
     Proceeding. This Guaranty is a guaranty of payment and not of collection.

          (b) Continuing Guaranty.  This Guaranty is an irrevocable continuing

     guaranty of the Guaranteed Obligations which shall continue in effect until
     all obligations of the Lenders to extend credit to Borrower have terminated
     and all of the Guaranteed Obligations have been fully, finally and
     indefeasibly paid.  If any payment on any Guaranteed Obligation is set
     aside, avoided or rescinded or otherwise recovered from Agent or any
     Lender, such recovered payment shall constitute a Guaranteed Obligation
     hereunder and, if this Guaranty was previously released or terminated, it
     automatically shall be fully reinstated, as if such payment was never made.

     other Guarantor hereunder, and a separate action or actions may be brought
     and prosecuted against each Guarantor irrespective of whether action is
     brought against Borrower, any other Guarantor or any other guarantor of the
     Guaranteed Obligations or whether Borrower, any other Guarantor or any
     other guarantor of the Guaranteed Obligations is joined in any such action
     or actions.

              ------------------------------                                    
     Guaranty, any court of competent jurisdiction determines that enforcement
     against any Guarantor for the full amount of the Guaranteed Obligations is
     not lawful under or would be subject to avoidance under Section 548 of the
     United States Bankruptcy Code or any applicable provision of any comparable
     law of any state or other jurisdiction, the liability of such Guarantor
     under this Guaranty shall be limited to the maximum amount lawful and not
     subject to such avoidance.

          (e) Termination.  Notwithstanding any termination of this Guaranty in
              -----------                                                      
     accordance with Paragraph 6 hereof, this Guaranty shall continue to be in
                     -----------

     rescinded or otherwise required to be surrendered by Agent or any Lender
     after receipt.

     Paragraph 5, each Guarantor hereby further waives (A) all rights and
     -----------                                                         
     defenses arising out of an election of remedies by Agent or any Lender,
     even though that election of remedies, such as a nonjudicial foreclosure
     with respect to security for a Guaranteed Obligation, has destroyed such
     Guarantor's rights of subrogation and reimbursement against Borrower by the
     operation of Section 580d of the Code of Civil Procedure or otherwise, (B)
     all rights and defenses such Guarantor may have by reason of protection
     afforded to Borrower with respect to the Guaranteed Obligations pursuant to
     the antideficiency or other laws of California limiting or discharging the
     Guaranteed Obligations, including, without limitation, Section 580a, 580b,
     580d, or 726 of the California Code of Civil Procedure, and (C) all other
     rights and defenses available to such Guarantor by reason of Sections 2787
     to 2855, inclusive, Section 2899 or Section 3433 of the California Civil
     Code or Section 3605 of the California Commercial Code.

          (c) Financial Condition of Borrower, Etc.  Each Guarantor is fully
              ------------------------------------                          
     aware of the financial condition and affairs of Borrower.  Each Guarantor
     has executed this Guaranty without reliance upon any representation,
     warranty, statement or information concerning Borrower furnished to such
     Guarantor by Agent or any Lender and has, independently and without
     reliance on Agent or any Lender, and based on such documents and
     information as it has deemed appropriate, made its own appraisal of the
     financial condition and affairs of Borrower and of other circumstances
     affecting the risk of nonpayment or nonperformance of the Guaranteed
     Obligations.  Each Guarantor is in a position to obtain, and assumes full
     responsibility for obtaining, any additional information about the
     financial condition and affairs of Borrower and of other circumstances
     affecting the risk of nonpayment or nonperformance of the Guaranteed
     Obligations and will, independently and without reliance upon Agent or any
     Lender, and based on such documents and information as it shall deem
     appropriate at the time, continue to make its own appraisals and decisions
     in taking or not taking action in connection with this Guaranty.


     6.   SUBORDINATION.  Each Guarantor hereby subordinates any and all debts,
          -------------

         (b)  Prior Payment of Guaranteed Obligations.  In any Insolvency

     before such Guarantor or any of its Subsidiaries receives payment of any
     Subordinated Obligations.

         (c)  Turn-Over.  After the occurrence and during the continuance of 
              ---------

     Guarantor and its Subsidiaries shall, if Agent or Required Lenders so
     requests, collect, enforce and receive payments on account of the
     Subordinated Obligations as trustee for Agent and the Lenders and deliver
     such payments to Agent on account of the Guaranteed Obligations (including
     any and all Disallowed Post-Commencement Interest and Expenses), together
     with any necessary endorsements or other instruments of transfer, but
     without reducing or affecting in any manner the liability of such Guarantor
     under the other provisions of this Guaranty.

         (d)  Agent Authorization.  After the occurrence and during the 
              -------------------

7.  GENERAL PLEDGE; SETOFF.
    ----------------------

         (a)  Pledge.  In addition to all liens upon and rights of setoff 
              ------
     against the property of any Guarantor given to Agent or any Lender by law
     or separate agreement to secure

                                     H-11
<PAGE>
 
     the liabilities of any Guarantor hereunder, to the extent permitted by law,
     each Guarantor hereby grants to Agent (for the ratable benefit of Agent and
     the Lenders), as security for such Guarantor's obligations hereunder, a
     security interest in all monies, deposit accounts, securities and other
     property of such Guarantor now or hereafter in the possession of or on
     deposit with Agent or any Lender, whether held in a general or special
     account or deposit, or for safekeeping or otherwise; and Agent shall have
     all rights and remedies of a secured party with respect to such property.

         (b)  Setoff.  In addition to any rights and remedies of Agent or any 
              ------
     Lender provided by law, Agent and the Lenders (with the prior consent of
     Agent) shall have the right, without prior notice to any Guarantor, any
     such notice being expressly waived by each Guarantor to the extent
     permitted by applicable law, upon the occurrence and during the continuance
     of a Default or an Event of Default, to set-off and apply against the
     Guaranteed Obligations any amount owing from Agent or any Lender to such
     Guarantor, including all deposits, accounts and moneys of such Guarantor

         (c)  Nonwaiver.  No security interest or right of setoff shall be 
              ---------
     deemed to have been waived by any act or conduct on the part of Agent or
     any Lender or by any failure to exercise such right of setoff or to enforce
     such security interest, or by any delay in so doing; and every right of
     setoff and security interest shall continue in full force and effect until
     such right of setoff or security interest is specifically waived or
     released by an instrument in writing executed by Agent.

     8.  CONTRIBUTION AMONG GUARANTORS.  The Guarantors desire to allocate among
         -----------------------------
themselves, in a fair and equitable manner, their rights of contribution from 
each other when any payment is made by any Guarantor under this Guaranty. 
Accordingly, if any payment is made by any Guarantor under this Guaranty (a 
"Funding Guarantor") that exceeds its Fair Share, the Funding Guarantor shall be
 -----------------
entitled to a contribution from each other Guarantor in the amount of such other
Guarantor's Fair Share Shortfall, so that all such contributions shall cause 
each Guarantor's Aggregate Guaranty Payments to equal its Fair Share. The 
amounts payable as contributions hereunder shall be determined by the Funding 
Guarantor as of the date on which the related payment or distribution is made by
the Funding Guarantor, and such determination shall be binding on the other 
Guarantors absent manifest error. The allocation and right of contribution among
the Guarantors set forth in this Paragraph 8 shall not be construed to limit in 
                                 -----------
any way the liability of any Guarantor under this Guaranty or the amount of the 
Guaranteed Obligations.
