        NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (unaudited)


Note 1 -          Basis of Presentation
                  ---------------------
                  The financial information at March 31, 1997, and for the
                  three and nine-month periods ended March 31, 1997 and 1996,
                  is unaudited, but includes all adjustments (consisting only of
                  normal recurring adjustments) which the management of
                  California Microwave, Inc. believes are necessary for a fair
                  presentation of the results for the periods presented. Interim
                  results are not necessarily indicative of results for a full
                  year. The consolidated interim financial statements should be
                  read in conjunction with the audited consolidated financial
                  statements for the year ended June 30, 1996 included in the
                  California Microwave, Inc. 1996 Annual Report to Stockholders.

                  In February 1997, The Financial Accounting Standards Board
                  issued Statement No.128, Earnings per Share, which is required
                  to be adopted on December 31, 1997. At that time, the Company
                  will be required to change the method currently used to
                  compute earnings per share and to restate all prior periods.
                  Under the new requirements for calculating primary earnings
                  per share, the dilutive effect of stock options will be
                  excluded. The impact is expected to result in an increase in
                  primary earnings per share in those periods in which the
                  Company has net income. The impact on primary earnings per
                  share for the quarter ended March 31, 1996 was not
                  significant. The impact of Statement 128 on fully diluted
                  earnings per share is also not significant.

Note 2 -          Restructuring and other charges
                  -------------------------------
                  As a result of continued disappointing operating performance
                  by the Microwave Network Systems (MNS) division and the
                  Satellite Transmission Systems (STS) division, the Company
                  performed a comprehensive review of these and certain other of
                  the Company's operations during December 1996 and January
                  1997, including a review of inventory levels, product
                  development and migration plans, and facility and personnel
                  needs. It was determined that MNS will focus on products that
                  have potentially higher margins and STS will focus on selected
                  strategic customers and network opportunities that utilize the
                  Company's products. This resulted in the write-off of certain
                  inventories, the restructuring of MNS and STS operations, and
                  the recording of charges relating to warranty and contract
                  issues that arose at MNS and STS during the second quarter.
                  Inventory, warranty and contract, and other charges of
                  approximately $39 million were reflected in the results of
                  operations for the second quarter. Restructuring charges of
                  approximately $8 million are reflected in the results of
                  operations in the third quarter. See Management's Discussion
                  and Analysis of Financial Condition and Results of Operations
                  for further information.

Note 3 -          Contingent Liabilities
                  ----------------------
                  On November 9, 1995, and December 12, 1995, two putative class
                  action lawsuits were filed in the United States District Court
                  for the Northern District of California. The plaintiffs in
                  these two cases, which have been consolidated, purport to
                  represent a class of all persons who purchased common stock of
                  the Company between September 6, 1994, and June 29, 1995 (the
                  class period). Named as defendants are the Company and certain
                  of its former executive officers. The Complaints allege that
                  defendants violated various federal securities laws through
                  material misrepresentations and omissions during the class
                  period. Defendants filed motions to dismiss the complaints,
                  which the court granted on April 19, 1996, with leave to
                  amend. Plaintiffs filed an amended consolidated complaint and
                  in August 1996 defendants filed a motion to dismiss that
                  complaint. On November 1, 1996, the motion to dismiss was
                  denied. Although the ultimate outcome of these proceedings
                  cannot be determined, the Company believes that it has
                  meritorious defenses to the claims alleged in these lawsuits
                  and intends to defend the actions vigorously.

                  The Company is subject to other legal proceedings and claims
                  that arise in the normal course of its business. The Company
                  believes these proceedings will not have a material adverse
                  effect on the financial position or results of operations of
                  the Company.

Note 5 -          Unbilled Accounts Receivable
                  ----------------------------
                  Included in accounts receivable at March 31, 1997 and June 30,
                  1996 are approximately $4.7 million and $7.5 million,
                  respectively, of unbilled receivables resulting from
                  provisions contained in certain export contracts.

                  The remaining unbilled receivables at March 31, 1997 are
                  expected to be billed and collected within one year.

Note 6 -          Stockholders' Equity 
                  --------------------
                  The change in capital in excess of par value for the nine
                  months ended March 31, 1997 consists principally of common
                  stock issuances and tax benefit of options exercised.

Note 7-           Reclassifications
                  -----------------
                  Certain fiscal year 1996 amounts have been reclassified to
                  conform to the fiscal 1997 presentation.

Note 8 -          Income Taxes
                  ------------
                  At March 31, 1997, the Company had a cumulative net deferred
                  tax asset of $26.6 million that will be available to reduce
                  payments on future tax liabilities. Management of the Company
                  believes it is more likely than not that the asset will be
                  realized through refunds of previously paid income taxes,
                  future profitable operations, and tax planning strategies.

Item 2.  Management's Discussion and Analysis of Financial Condition and 
         Results of Operations

Statements made below and elsewhere in this Form 10-Q that are not historical
facts, including any statements about expectations for fiscal year 1997 and
beyond, involve certain risks and uncertainties. Factors that could cause the
Company's actual results to differ materially from management's projections,
estimates and expectations include, but are not limited to, delays in the
receipt of orders or in the shipment of products, delays in implementing the
Company's restructuring plan, delays in transitioning from older to newer
products, and other factors referred to under "Information Regarding Forward
Looking Statements" in the Company's Form 10-K Annual Report for its fiscal year
ended June 30, 1996, and in the Company's Consolidated Financial Statements and
Notes to Financial Statements contained in its 1996 Annual Report to
Stockholders. The Condensed Consolidated Financial Statements and Notes to
Condensed Consolidated Financial Statements should be read in conjunction with
this Management's Discussion and Analysis of Financial Condition and Results of
Operations.

OVERVIEW

       As a result of continued disappointing operating performance by the
Microwave Network Systems (MNS) division and the Satellite Transmission Systems
(STS) division, management of the Company performed a comprehensive review of
these and certain other of the Company's operations during December 1996 and
January 1997. MNS represents the merged operations of TeleSciences Transmission
Systems (TTS), acquired in October 1993, Microwave Networks Incorporated,
acquired in May 1995, and certain operations of Microwave Radio Corporation,
acquired in April 1992. This comprehensive





                                      -7-
<PAGE>   8

review included a review of inventory levels, product development and migration
plans, facility and personnel needs, and other matters. As a result of this
review, it was determined that MNS will focus on a smaller number of potentially
higher-margin products, including several recently introduced products, and STS
will focus on selected strategic customers and networking opportunities that
utilize the Company's products. As a result of this product strategy, the
operations of MNS are in the process of being reorganized into two divisions,
one focused on the international cellular market and the other focused on the
domestic Personal Communications Services (PCS) relocation market. MNS will
immediately discontinue the sale of certain products and will phase-out other
products over the next 6 to 18 months. STS will also eliminate certain products
and will transfer others to the Company's EFData subsidiary (EFD). Accordingly,
management determined that certain quantities of inventory on-hand or subject to
firm purchase commitments at MNS and STS, and to a lesser extent at certain
other divisions, were in excess of reforecasted demand. As a result of such
review, including the decision to discontinue or phase-out certain products, the
Company recorded a provision of $31.2 million during the quarter ended December
31, 1996, to write-down certain inventories to their estimated net realizable
value.

       In addition, certain customers of MNS have experienced quality problems
with a specific product (now discontinued) which was sold in significant
quantities during 1993 to 1995. After determining the scope of the quality
problem, the Company recently offered to retrofit the affected products at no
cost to the customer. The Company has recorded a provision for the estimated
costs of this program. The Company also determined that warranty and other
provisions should be made for other discontinued products and for certain loss
contracts. Warranty and contract loss provisions recorded in the quarter ended
December 31, 1996 amounted to $6.5 million.

       Primarily as a result of the above, during the quarter ended December 31,
1996, the Company recorded $38.0 million to cost of products sold and $1.3
million to marketing and administration expense for the write-down of
inventories to amounts expected to be realized, the recognition of unusual
warranty and contract costs, and other expenses. Only approximately $7.0
million of the total of $39.3 million will result in future cash outlays. The
comprehensive review of operations also resulted in the decision to reduce
future operating expenses through the closure of certain facilities at MNS and
the termination of approximately 175 employees at MNS and STS. The Company
recognized approximately $7.8 million of restructuring charges, of which $6.9
million relates to facility closures and the remainder to severance charges. As
required by generally accepted accounting principles, these restructuring
charges were recorded in the quarter ended March 31, 1997. The Company also
expects aggregate costs of approximately $1 million for the fourth quarter of
fiscal 1997 and the first quarter of fiscal 1998 for retention and relocation
costs for certain employees and other expenses to be incurred in connection
with the restructuring. These costs will be included in marketing and
administration expense and research and development expense in those periods.
Relocation expenses incurred during the quarter ended March 31, 1997, were
approximately $800,000.

       As a part of the review process, and in accordance with its accounting
policies, the Company reviewed the $10 million carrying value of intangible
assets associated with the acquisition of TTS. The Company concluded that the
asset will be realized through the on-going domestic operations of MNS. However,
the remaining period over which this asset will be realized has been shortened
to 13 years from 26 years.

       In June 1995, the Company recorded restructuring charges of approximately
$20.9 million and other charges of approximately $15.5 million, for a total of
approximately $36.4 million in connection with a program to reduce costs and
improve operating efficiencies. Through March 31, 1997, asset writedowns and
payments in connection with the 1995 charges totaled approximately $33.5 million
leaving approximately $2.9 million to be paid.

RESULTS OF OPERATIONS

       Sales   Sales were $92.9 million and $100.1 million for the three months
ended March 31, 1997 and 1996, respectively, representing a decrease of 7%.
Wireless product sales and intelligence systems and other sales increased 8% and
16%, respectively, while satellite communication sales decreased 34%. 





                                      -8-
<PAGE>   9

The decrease in satellite communications sales was principally due to continued
delays in completing the financing of certain large satellite earth station
projects and the decrease in sales for a telecommunications project in Saudi
Arabia as this project was substantially completed in fiscal 1996 and has not
been replaced by similar projects in fiscal 1997. The Company expects that
satellite communication sales for the fourth quarter will be below satellite
communication sales recorded in the fourth quarter of fiscal 1996.

       U.S. commercial sales, sales to the U.S. government and international
sales for the three months ended March 31, 1997 decreased 2%, 4% and 13%,
respectively, when compared to the third quarter of fiscal 1996. Products
represented 69% of sales in the third quarter of 1997 compared to 63% in the
third quarter of 1996, with the balance represented by system sales.

       Sales were $313.6 million and $332.1 million for the nine months ended
March 31, 1997 and 1996, respectively, representing a decrease of 6%. Wireless
sales and intelligence systems and other sales increased 12% and 29%,
respectively, substantially offsetting a 32% decrease in satellite
communications sales. U.S. commercial sales and sales to the U.S. government
increased 3% and 9%, respectively, while international sales decreased 17%.
Satellite communications and international sales declined because the Saudi
Arabia project was not replaced.

       Gross Margin   Gross margin was $27.1 million and $29.7 million for the
three months ended March 31, 1997 and 1996, respectively. Gross margin as a
percentage of total sales was 29.2% and 29.7%, respectively, for such periods.
Continued competitive pricing, particularly at EFData, continues to limit
increases in gross margins on product sales.

       Gross margin was $45.8 million and $98.6 million for the nine months
ended March 31, 1997 and 1996, respectively, representing a decrease of 54%.
Gross margin as a percentage of sales was 26.7% (excluding the second quarter
charges discussed in the overview above) and 29.7% for such periods,
respectively.

       Research and Development   Research and development expenses were $7.5
million and $7.7 million for the three months ended March 31, 1997 and 1996,
respectively, representing a decrease of 2%. Research and development expenses
as a percentage of total sales were 8.1% and 7.7% for such periods,
respectively. The Company continues to focus its research and development
efforts primarily on the development of new satellite networking products and
networking software and wireless products.

       Research and development expenses were $23.3 million and $22.4 million
for the nine months ended March 31, 1997 and 1996, respectively, representing an
increase of 4%. Research and development expenses as a percentage of total sales
were 7.4% and 6.7% for such periods, respectively.

       Marketing and Administration   Marketing and administration expenses were
$18.7 million and $18.4 million for the three months ended March 31, 1997 and
1996, respectively, representing an increase of 2%. Marketing and administration
expenses as a percentage of total sales were 20.1% and 18.4% for such periods,
respectively.

       Marketing and administration expenses were $61.2 million and $55.7
million for the nine months ended March 31, 1997 and 1996 respectively,
representing an increase of 10%. Marketing and administration expenses as a
percentage of total sales were 19.5% and 16.8% for such periods, respectively.
Included in marketing and administration expenses for the quarter ended December
31, 1996, is approximately $1.3 million of severance charges for the Company's
former chief executive officer.

       Amortization of Intangible Assets   Amortization expenses associated with
intangible assets increased by approximately $100,000 during the three months
and nine months ended March 31, 1997. This increase is due to the change in the
remaining amortization period for the TTS intangible assets of approximately $10
million from 26 years to 13 years.

<PAGE>   10

       Restructure Charges   The Company recorded $7.8 million of restructuring
charges in the third quarter of fiscal 1997. The amount consists of $800,000 for
employee severance, of which $334,000 was paid during the third quarter, and the
balance of $7.0 million relates to facility closures and is expected to be
incurred over the next 5 years.

       Interest Expense, Net   Net interest expense was $1.4 million and $0.9
million for the three months ended March 31, 1997 and 1996, respectively,
representing a increase of 53%. Net interest expense was $4.2 million and $3.1
million for the nine months ended March 31, 1997 and 1996, respectively,
representing a 38% increase. The increase in net interest expense reflects the
need for the Company to borrow against its credit lines to fund operations and
capital expenditures.

       Gain on Sale of Subsidiary   During the second quarter of fiscal 1996,
the Company recognized a $2.7 million gain from the sale of its Digital Radio
Technology subsidiary.

       Provision for (Benefit from) Income Taxes   The provision for (benefit
from) income taxes was ($3.0) million and $0.7 million for the three months
ended March 31, 1997 and 1996, respectively, and ($16.4) million and $5.7
million for the nine months ended March 31, 1997 and 1996 respectively. The
effective tax rate benefit of 33% for fiscal 1997 represents the federal
statutory rate of 35% reduced for the effect of non-deductible amortization of
goodwill (for tax purposes).

       At March 31, 1996, the Company had a cumulative net deferred tax asset of
$26.6 million that will be available to reduce payments on future tax
liabilities. Management of the Company believes it is more likely than not that
the asset will be realized through refunds of previously paid income taxes,
future profitable operations, and tax planning strategies.

LIQUIDITY AND CAPITAL RESOURCES

       At March 31, 1997, the Company had working capital of $113.5 million,
including $1.6 million of cash and cash equivalents, compared with working
capital of $141.3 million, including cash and cash equivalents of $4.6 million,
at June 30, 1996.

       During the first nine months of fiscal 1997, cash and cash equivalents
were provided by operations (after adjusting the operating loss for depreciation
and amortization and charges discussed in the overview) and decreases in
accounts receivable, offset by reductions of accounts payable. Cash and cash
equivalents were used to pay year-end accrued liabilities, including payments
under incentive agreements and employee benefit plans and certain restructuring
payments. The net result was cash and cash equivalents provided by operations of
$1.2 million. During the first nine months of fiscal 1996, cash and cash
equivalents were provided by operating income (including depreciation and
amortization ) and decreases in inventories, and were used to fund an increase
in accounts receivable and to reduce accounts payable and to pay year-end
accrued liabilities. The net result was cash and cash equivalents provided by
operating activities of $10.4 million.

       The Company's investing activities during the first nine months of fiscal
1997 included capital expenditures of $9.3 million. Total cash used for
investing activities was $8.3 million. Net cash used for investing activities
during the first nine months of fiscal 1996 was $15.5 million, which included
$14.8 million of capital expenditures.

       During the first nine months of fiscal 1997, cash and cash equivalents of
$4.1 million were provided by financing activities, including borrowings of $1
million under the Company's credit lines and sales of $3.2 million of common
stock to employees under on-going stock option and purchase plans. During the
first nine months of 1996, the Company sold $3.5 million of common stock to its
employees.

       The above activity resulted in a net decrease in cash and cash
equivalents of $2.9 million for the first nine months of fiscal 1997 compared to
a net decrease in cash and cash equivalents of $0.5 million for the first nine
months of fiscal 1996.

     In December 1996, the Company amended its principal credit facility. The

facility was reduced to $30 million and is secured by the Company's current
assets. The amended facility expires March 1998. As of March 31, 1997, there
were $11.5 million of borrowings and $5.0 million of standby letters of credit
outstanding under this facility, leaving $13.5 million of available credit. At
March 31, 1997, the Company was not in compliance with certain covenants of its 
debt agreements. The lenders have waived such non-compliance and amended such
covenants as necessary to bring the Company into compliance at March 31, 1997.
In May, the Company expects to replace this credit facility with a new 3 year
credit facility with availability based upon an accounts receivable formula.
This new facility will be secured by current and intangible assets and will
require .25% annual commitment fees. Interest rates for borrowings will not
exceed the bank's reference rate plus 0.5%.

       The Company has sold certain qualified export receivables to a bank,
these receivables are insured for 95% of their value and the remaining uninsured
5% is with full recourse to CMI. At March 31, 1997, the outstanding balances of
sold and uncollected receivable balances approximated $12.0 million.

       The Company believes that its current cash position, funds generated from
operations and funds available from its credit facilities will be adequate to
meet the Company's requirements for working capital, capital expenditures and
debt service for at least the next 12 months.

OTHER FINANCIAL INFORMATION

       Bookings   Orders booked were $115.7 million and $90.4 million for the
three months ended March 31, 1997 and 1996, respectively, representing an
increase of 28%. Bookings increased in all product areas when compared to the
third quarter of fiscal 1996. Intelligence systems bookings increased by 157% to
$31.9 million and represent 27% of total bookings, wireless increased by 8% to
38% of total bookings and satellite communications by 7% to 35% of total
bookings.

       Backlog   Backlog was $181.8 million and $206.0 million at March 31, 1997
and 1996, respectively, representing a decrease of 12%. Substantially all of the
March 31, 1997 backlog is expected to be delivered within twelve months.

                                   ARTICLE II

                                  THE CREDITS

         2.01    Amounts and Terms of Commitments.  Each Bank severally agrees,
on the terms and conditions set forth herein, to make loans to the Company
(each such loan, a "Revolving Loan") from time to time on any Business Day
during the period from the Closing Date to the Revolving Termination Date, in
an aggregate amount not to exceed at any time outstanding the amount set forth
on Schedule 2.01 (such amount as the same may be reduced under Subsection 2.05
or as a result of one or more assignments under Section 11.08, the Bank's
"Commitment"); provided, however, that, after giving effect to any Borrowing of
Revolving Loans, the Effective Amount of all outstanding Revolving Loans and
the Effective Amount of all L/C Obligations, shall not at any time exceed the
lower of the:  (i) combined Commitments, and (ii) then applicable Aggregate
Borrowing Base; and provided further, that the Effective Amount of the
Revolving Loans of any Bank plus the participation of such Bank in the
Effective Amount of all L/C Obligations shall not at any time exceed such
Bank's Commitment.  Within the limits of each Bank's Commitment, and subject to
the other terms and conditions hereof, the Company may borrow under this
Section 2.01, prepay under Section 2.06 and reborrow under this Section 2.01.

         2.02    Loan Accounts.

                 (a)      The Loans made by each Bank and the Letters of Credit
Issued by the Issuing Bank shall be evidenced by one or more accounts or
records maintained by such Bank or Issuing Bank, as the case may be, in the
ordinary course of business.  The accounts or records maintained by the Agent,
the Issuing Bank, and each Bank shall be conclusive, absent manifest error, of
the amount of the Loans made by the Banks to the Company and the Letters of
Credit Issued for the account of the Company, and the interest and payments
thereon.  Any failure so to record or any error in doing so shall not, however,
limit or otherwise affect the obligation of the Company hereunder to pay any
amount owing with respect to the Loans or any Letter of Credit.

                 (b)      Upon the request of any Bank, made through the Agent,
the Loans made by such Bank may be evidenced by one or more Notes, instead of
or in addition to loan accounts.  Each such Bank shall endorse on the schedules
annexed to its Note(s) the date, amount and maturity of each Loan made by it
and the amount of each payment of principal





                                       26
<PAGE>   34
made by the Company with respect thereto.  Each such Bank is irrevocably
authorized by the Company to endorse its Note(s) and each Bank's record shall
be conclusive, absent manifest error; provided, however, that the failure of a
Bank to make, or an error in making, a notation thereon with respect to any
Loan shall not limit or otherwise affect the obligations of the Company
hereunder or under any such Note to such Bank.

         2.03    Procedure for Borrowing.

                 (a)      Each Borrowing of Revolving Loans shall be made upon
the Company's irrevocable written notice delivered to the Agent in the form of
a Notice of Borrowing which notice must be received by the Agent (i) prior to
11:00 a.m. (San Francisco time) three Business Days prior to the requested
Borrowing Date in the case of Offshore Rate Loans, or (ii) prior to 8:00 a.m.
(San Francisco time) on the requested Borrowing Date in the case of Base Rate
Loans; specifying:  (A) the amount of the Borrowing (which shall be in an
aggregate minimum amount of $2,000,000 in the case of Offshore Rate Loans and
$1,000,000 in the case of Base Rate Loans, or any integral multiple of $500,000
in excess thereof); (B) the requested Borrowing Date, which shall be a Business
Day; (C) the Type of Loans comprising the Borrowing (provided that any Loan
made on the Closing Date shall only consist of Base Rate Loans); and (D) with
respect to Offshore Rate Loans, the duration of the Interest Period applicable
to such Loans.  If the Notice of Borrowing fails to specify the duration of the
Interest Period for any Borrowing comprised of Offshore Rate Loans, such
Interest Period shall be three months.

         The Agent will promptly notify each Bank of its receipt of any Notice
of Borrowing and of the amount of such Bank's Pro Rata Share of that Borrowing.
Each Bank will make the amount of its Pro Rata Share of each Borrowing
available to the Agent for the account of the Company at the Agent's Payment
Office by 11:00 a.m. (San Francisco time) on the Borrowing Date requested by
the Company in funds immediately available to the Agent.  The proceeds of all
such Loans will then be made available to the Company by the Agent at such
office by crediting the account of the Company on the books of BofA with the
aggregate of the amounts made available to the Agent by the Banks and in like
funds as received by the Agent.

                 (b)      After giving effect to any Borrowing, unless the
Agent shall otherwise consent, there may not be more than six different
Interest Periods in effect.

         2.04    Conversion and Continuation Elections.

                 (a)      The Company may, upon irrevocable written notice to
the Agent in accordance with subsection 2.04(b):  (i) elect, as of any Business
Day, in the case of Base Rate Loans, or as of the last day of the applicable
Interest Period, in the case of Offshore Rate Loans, to convert any such Loans
(or any part thereof in an amount not less than $2,000,000 in the case of
Offshore Rate Loans and $1,000,000 in the case of Base Rate Loans, or that is
in an integral multiple of $500,000 in excess thereof) into Loans of any other
Type; or (ii) elect as of the last day of the applicable Interest Period, to
continue any Offshore Rate





                                       27
<PAGE>   35
Loans having Interest Periods expiring on such day (or any part thereof in an
amount not less than $2,000,000, or that is in an integral multiple of $500,000
in excess thereof);

provided, that if at any time the aggregate amount of Offshore Rate Loans in
respect of any Borrowing is reduced, by payment, prepayment, or conversion of
part thereof to be less than $2,000,000, such Offshore Rate Loans shall
automatically convert into Base Rate Loans, and on and after such date the
right of the Company to continue such Loans as, and convert such Loans into,
Offshore Rate Loans shall terminate.

                 (b)      The Company shall deliver a Notice of
Conversion/Continuation to be received by the Agent not later than (i) 8:00
a.m.  (San Francisco time) on the Conversion/Continuation Date, if the Loans
are to be converted into Base Rate Loans; and (ii) 11:00 a.m. (San Francisco
time) three Business Days in advance of the Conversion/Continuation Date, if
the Loans are to be converted into or continued as Offshore Rate Loans;
specifying:  (A) the proposed Conversion/Continuation Date; (B) the aggregate
amount of Loans to be converted or continued; (C) the Type of Loans resulting
from the proposed conversion or continuation; and (D) other than in the case of
conversions into Base Rate Loans, the duration of the requested Interest
Period.  If the Notice of Conversion/Continuation fails to specify the duration
of the Interest Period for any Base Rate Loan to be converted into an Offshore
Rate Loan, such Interest Period shall be three months.

                 (c)      If upon the expiration of any Interest Period
applicable to Offshore Rate Loans, the Company has failed to select timely a
new Interest Period to be applicable to such Offshore Rate Loans or if any
Default or Event of Default then exists, the Company shall be deemed to have
elected to convert such Offshore Rate Loans into Base Rate Loans effective as
of the expiration date of such Interest Period.

                 (d)      The Agent will promptly notify each Bank of its
receipt of a Notice of Conversion/Continuation, or, if no timely notice is
provided by the Company, the Agent will promptly notify each Bank of the
details of any automatic conversion.  All conversions and continuations shall
be made ratably according to the respective outstanding principal amounts of
the Loans with respect to which the notice was given held by each Bank.

                 (e)      Unless the Majority Banks otherwise consent, during
the existence of a Default or Event of Default, the Company may not elect to
have a Loan converted into or continued as an Offshore Rate Loan.

                 (f)      After giving effect to any conversion or continuation
of Loans, unless the Agent shall otherwise consent, there may not be more than
six different Interest Periods in effect.

         2.05    Voluntary Termination or Reduction of Commitments.  The
Company may, upon not less than five Business Days' prior notice to the Agent,
terminate the Commitments, or permanently reduce the Commitments by an
aggregate amount of $5,000,000 or more; unless, after giving effect thereto and
to any prepayments of Loans made on the effective date





                                       28
<PAGE>   36
thereof, (a) the Effective Amount of all Revolving Loans and L/C Obligations
together would exceed the amount of the combined Commitments then in effect, or
(b) the Effective Amount of all L/C Obligations then outstanding would exceed
the L/C Commitment.  Once reduced in accordance with this Section, the
Commitments may not be increased.  Any reduction of the Commitments shall be
applied to each Bank according to its Pro Rata Share.  If and to the extent
specified by the Company in the notice to the Agent, some or all of the
reduction in the combined Commitments may be applied to reduce the L/C
Commitment.  All accrued commitment fees to, but not including, the effective
date of any termination of Commitments, shall be paid on the effective date of
such termination.

         2.06    Optional Prepayments.  Subject to Section 4.04, the Company
may, at any time or from time to time, upon delivery of a Notice of Prepayment
to the Agent (a) prior to 11:00 a.m. (San Francisco time) three Business Days
prior to the date of prepayment in the case of Offshore Rate Loans, or (b)
prior to 11:00 a.m. (San Francisco time) on the date of prepayment in the case
of Base Rate Loans, ratably prepay Loans in whole or in part in minimum amounts
of $2,000,000 in the case of Offshore Rate Loans and $1,000,000 in the case of
Base Rate Loans, or any integral multiple of $500,000 in excess thereof.  The
Agent will promptly notify each Bank of its receipt of any such notice, and of
such Bank's Pro Rata Share of such prepayment.  If such notice is given by the
Company, the Company shall make such prepayment and the payment amount
specified in such notice shall be due and payable on the date specified
therein, together with accrued interest and accrued Utilization Fee to each
such date on the amount prepaid and any amounts required pursuant to Section
4.04.

         2.07    Cash Collateralization and Mandatory Prepayments of Loans.  If
at any time (a) the Effective Amount of Outstanding Loans and L/C Obligations
shall exceed the lower of:  (i) the then applicable Aggregate Borrowing Base,
(ii) the combined Commitments, or (iii) the L/C Commitment, the Company shall
immediately (x) prepay such amount of the outstanding principal amount of the
Loans and/or (y) Cash Collateralize such amount of the outstanding L/C
Obligations, as is necessary to make the then applicable Effective Amount less
than or equal to the lower of:  (i) the then Applicable Aggregate Borrowing
Base, (ii) the Combined Commitments, or (iii) the L/C Commitment, as
appropriate.

         2.08    Repayment.  The Company shall repay to the Banks on the
Revolving Termination Date the aggregate principal amount of Loans outstanding
on such date.

         2.09    Interest.

                 (a)      Each Revolving Loan shall bear interest on the
outstanding principal amount thereof from the applicable Borrowing Date at a
rate per annum equal to the Offshore Rate or the Base Rate as appropriate
(subject to the Company's right to convert to other Types of Loans under
Section 2.04) plus the Applicable Margin.  Applicable Margin shall equal an
interest rate per annum specified in basis points to be added to the Offshore
Rate or the Base Rate, as applicable, which shall be determined in accordance
with the following table:

                 (b)      Interest on each Revolving Loan shall be paid in
arrears on each Interest Payment Date.  Interest shall also be paid on the date
of any prepayment of Loans under Section 2.06 or 2.07 for the portion of the
Loans so prepaid and upon payment (including prepayment) in full thereof and,
during the existence of any Event of Default, interest shall be paid on demand
of the Agent at the request or with the consent of the Majority Banks.

                 (c)      Notwithstanding subsection (a) of this Section, if
any amount of principal of or interest on any Loan, or any other amount payable
hereunder or under any other Loan Document is not paid in full when due
(whether at stated maturity, by acceleration, demand or otherwise), the Company
agrees to pay interest on such unpaid principal or other amount, from the date
such amount becomes due until the date such amount is paid in full, and after
as well as before any entry of judgment thereon to the extent permitted by law,
payable on demand, at a fluctuating rate per annum equal to the Base Rate plus
2%.

                 (d)      Anything herein to the contrary notwithstanding, the
obligations of the Company to any Bank hereunder shall be subject to the
limitation that payments of interest shall not be required for any period for
which interest is computed hereunder, to the extent (but only to the extent)
that contracting for or receiving such payment by such Bank would be contrary
to the provisions of any law applicable to such Bank limiting the highest rate
of interest that may be lawfully contracted for, charged or received by such
Bank, and in such event the Company shall pay such Bank interest at the highest
rate permitted by applicable law.

         2.10    Fees.  In addition to certain fees described in Section 3.08:

an agency fee to the Agent for the Agent's own account, as required by the
letter agreement ("Fee Letter") between the Company and the Arranger and Agent
dated December 23, 1996.

for the account of each Bank a commitment fee on the average daily unused
portion of such Bank's Commitment, computed on a quarterly basis in arrears on
the last Business Day of each calendar quarter based upon the daily utilization
for that quarter as calculated by the Agent, equal to the rate per annum
specified in the table in subsection 2.10(c).  For purposes of calculating
utilization under this subsection, the Commitments shall be deemed used only to
the extent of the Effective Amount of Revolving Loans plus the Effective Amount
of L/C Obligations then outstanding.  Such commitment fee shall accrue from the
Closing Date to the

such termination.  The commitment fees provided in this subsection shall accrue
at all times after the Closing Date, including at any time during which one or
more conditions in Article V are not met.

arrears and on the Revolving Termination Date beginning with the first calendar
quarter ending after February 28, 1997.

                 (e)      Amendment Fees.  The Company shall pay to the Agent,
for the ratable benefit of the Banks, an amendment fee equal to $25,000 for
each Bank payable upon the Closing Date together with an additional fee equal
to $10,000 for each Bank payable on March 1, 1997 provided that the facility
granted pursuant to this Agreement is still in effect on such date.

         2.11    Computation of Fees and Interest.

                 (a)      All computations of interest for Base Rate Loans when
the Base Rate is determined by BofA's "reference rate" shall be made on the
basis of a year of 365 or 366 days, as the case may be, and actual days
elapsed.  All other computations of fees and interest shall be made on the
basis of a 360-day year and actual days elapsed (which results in more interest
being paid than if computed on the basis of a 365-day year).  Interest and fees
shall





                                       31
<PAGE>   39
accrue during each period during which interest or such fees are computed from
the first day thereof to the last day thereof.

                 (b)      Each determination of an interest rate by the Agent
shall be conclusive and binding on the Company and the Banks in the absence of
manifest error.

         2.12    Payments by the Company.

                 (a)      All payments to be made by the Company shall be made
without set-off, recoupment or counterclaim.  Except as otherwise expressly
provided herein, all payments by the Company shall be made to the Agent for the
account of the Banks at the Agent's Payment Office, and shall be made in
dollars and in immediately available funds, no later than 11:00 a.m. (San
Francisco time) on the date specified herein.  The Agent will promptly
distribute to each Bank its Pro Rata Share (or other applicable share as
expressly provided herein) of such payment in like funds as received.  Any
payment received by the Agent later than 11:00 a.m. (San Francisco time) shall
be deemed to have been received on the following Business Day and any
applicable interest or fee shall continue to accrue.

                 (b)      Subject to the provisions set forth in the definition
of "Interest Period" herein, whenever any payment is due on a day other than a
Business Day, such payment shall be made on the following Business Day, and
such extension of time shall in such case be included in the computation of
interest or fees, as the case may be.

                 (c)      Unless the Agent receives notice from the Company
prior to the date on which any payment is due to the Banks that the Company
will not make such payment in full as and when required, the Agent may assume
that the Company has made such payment in full to the Agent on such date in
immediately available funds and the Agent may (but shall not be so required),
in reliance upon such assumption, distribute to each Bank on such due date an
amount equal to the amount then due such Bank.  If and to the extent the
Company has not made such payment in full to the Agent, each Bank shall repay
to the Agent on demand such amount distributed to such Bank, together with
interest thereon at the Federal Funds Rate for each day from the date such
amount is distributed to such Bank until the date repaid.

         2.13    Payments by the Banks to the Agent.

                 (a)      Unless the Agent receives notice from a Bank on or
prior to the Closing Date or, with respect to any Borrowing after the Closing
Date, at least one Business Day prior to the date of such Borrowing, that such
Bank will not make available as and when required hereunder to the Agent for
the account of the Company the amount of that Bank's Pro Rata Share of the
Borrowing, the Agent may assume that each Bank has made such amount available
to the Agent in immediately available funds on the Borrowing Date and the Agent
may (but shall not be so required), in reliance upon such assumption, make
available to the Company on such date a corresponding amount.  If and to the
extent any Bank shall not have made its full amount available to the Agent in
immediately available funds and the Agent in such circumstances has made
available to the Company such amount, that Bank shall on the





                                       32
<PAGE>   40
Business Day following such Borrowing Date make such amount available to the
Agent, together with interest at the Federal Funds Rate for each day during
such period.  A notice of the Agent submitted to any Bank with respect to
amounts owing under this subsection (a) shall be conclusive, absent manifest
error.  If such amount is so made available, such payment to the Agent shall
constitute such Bank's Loan on the date of Borrowing for all purposes of this
Agreement.  If such amount is not made available to the Agent on the Business
Day following the Borrowing Date, the Agent will notify the Company of such
failure to fund and, upon demand by the Agent, the Company shall pay such
amount to the Agent for the Agent's account, together with interest thereon for
each day elapsed since the date of such Borrowing, at a rate per annum equal to
the interest rate applicable at the time to the Loans comprising such
Borrowing.

                 (b)      The failure of any Bank to make any Loan on any
Borrowing Date shall not relieve any other Bank of any obligation hereunder to
make a Loan on such Borrowing Date, but no Bank shall be responsible for the
failure of any other Bank to make the Loan to be made by such other Bank on any
Borrowing Date.

         2.14    Sharing of Payments, Etc.  If, other than as expressly
provided elsewhere herein, any Bank shall obtain on account of the Loans made
by it any payment (whether voluntary, involuntary, through the exercise of any
right of set-off, or otherwise) in excess of its ratable share (or other share
contemplated hereunder), such Bank shall immediately (a) notify the Agent of
such fact, and (b) purchase from the other Banks such participations in the
Loans made by them as shall be necessary to cause such purchasing Bank to share
the excess payment pro rata with each of them; provided, however, that if all
or any portion of such excess payment is thereafter recovered from the
purchasing Bank, such purchase shall to that extent be rescinded and each other
Bank shall repay to the purchasing Bank the purchase price paid therefor,
together with an amount equal to such paying Bank's ratable share (according to
the proportion of (i) the amount of such paying Bank's required repayment to
(ii) the total amount so recovered from the purchasing Bank) of any interest or
other amount paid or payable by the purchasing Bank in respect of the total
amount so recovered.  The Company agrees that any Bank so purchasing a
participation from another Bank may, to the fullest extent permitted by law,
exercise all its rights of payment (including the right of set-off, but subject
to Section 11.10) with respect to such participation as fully as if such Bank
were the direct creditor of the Company in the amount of such participation.
The Agent will keep records (which shall be conclusive and binding in the
absence of manifest error) of participations purchased under this Section and
will in each case notify the Banks following any such purchases or repayments.

         2.15    Security.  All obligations of the Company and the Guarantors
under the Loan Documents shall be secured in accordance with the Collateral
Documents.

                             THE LETTERS OF CREDIT

         3.01    The Letter of Credit Subfacility.

                 (a)      On the terms and conditions set forth herein (i) the
Issuing Bank agrees, (A) from time to time on any Business Day during the
period from the Closing Date to the Revolving Termination Date to issue Letters
of Credit for the account of the Company, and to amend or renew Letters of
Credit previously issued by it, in accordance with subsections 3.02(c) and
3.02(d), and (B) to honor drafts under the Letters of Credit; and (ii) the
Banks severally agree to participate in Letters of Credit Issued for the
account of the Company; provided, that the Issuing Bank shall not be obligated
to Issue, and no Bank shall be obligated to participate in, any Letter of
Credit if as of the date of Issuance of such Letter of Credit (the "Issuance
Date") (1) the Effective Amount of all L/C Obligations plus the Effective
Amount of all Revolving Loans exceeds the lesser of (x) the combined
Commitments, or (y) the then applicable Aggregate Borrowing Base, (2) the
participation of any Bank in the Effective Amount of all L/C Obligations plus
the Effective Amount of the Revolving Loans of such Bank exceeds the lesser of
(x) such Bank's Commitment or (y) the then applicable Aggregate Borrowing Base,
(3) the Effective Amount of L/C Obligations exceeds the L/C Commitment, or (4)
the Effective Amount of L/C Obligations with respect to Letters of Credit which
may be drawn in support of the performance of financial obligations exceeds
$5,000,000.  Within the foregoing limits, and subject to the other terms and
conditions hereof, the Company's ability to obtain Letters of Credit shall be
fully revolving, and, accordingly, the Company may, during the foregoing
period, obtain Letters of Credit to replace Letters of Credit which have
expired or which have been drawn upon and reimbursed.

                 (b)      The Issuing Bank is under no obligation to Issue any
Letter of Credit if:  (i) any order, judgment or decree of any Governmental
Authority or arbitrator shall by its terms purport to enjoin or restrain the
Issuing Bank from Issuing such Letter of Credit, or any Requirement of Law
applicable to the Issuing Bank or any request or directive (whether or not
having the force of law) from any Governmental Authority with jurisdiction over
the Issuing Bank shall prohibit, or request that the Issuing Bank refrain from,
the Issuance of letters of credit generally or such Letter of Credit in
particular or shall impose upon the Issuing Bank with respect to such Letter of
Credit any restriction, reserve or capital requirement (for which the Issuing
Bank is not otherwise compensated hereunder) not in effect on the Closing Date,
or shall impose upon the Issuing Bank any unreimbursed loss, cost or expense
which was not applicable on the Closing Date and which the Issuing Bank in good
faith deems material to it; (ii) the Issuing Bank has received written notice
from any Bank, the Agent or the Company, on or prior to the Business Day prior
to the requested date of Issuance of such Letter of Credit, that one or more of
the applicable conditions contained in Article V is not then satisfied; (iii)
the expiry date of any requested Letter of Credit is (i) more than 27 months
after the Closing Date, or (ii) more than 365 days after the requested date of
the Issuance of such Letter of Credit; (iv) the expiry date of any requested
Letter of Credit is prior to the maturity date of any financial obligation to
be supported by the requested Letter of Credit; (v) any





                                       34
<PAGE>   42
requested Letter of Credit does not provide for drafts, or is not otherwise in
form and substance acceptable to the Issuing Bank, or the Issuance of a Letter
of Credit shall violate any applicable policies of the Issuing Bank; or (vi)
any standby Letter of Credit is for the purpose of supporting the issuance of
any letter of credit by any other Person.

         3.02    Issuance, Amendment and Renewal of Letters of Credit.

                 (a)      Each Letter of Credit shall be issued upon the
irrevocable written request of the Company received by the Issuing Bank (with a
copy sent by the Company to the Agent) at least four days (or such shorter time
as the Issuing Bank may agree in a particular instance in its sole discretion)
prior to the proposed date of issuance.  Each such request for issuance of a
Letter of Credit shall be in the form of an L/C Application, and shall specify
in form and detail satisfactory to the Issuing Bank: (i) the face amount of the
Letter of Credit denominated in Dollars or an Offshore Currency; (ii) the
expiry date of the Letter of Credit (which date shall not exceed either of the
limits specified in Section 3.01(b)(iii)); (iii) the name and address of the
beneficiary thereof; (iv) the documents to be presented by the beneficiary of
the Letter of Credit in case of any drawing thereunder; (v) the full text of
any certificate to be presented by the beneficiary in case of any drawing
thereunder; and (vi) such other matters as the Issuing Bank may require.  The
Company may delegate authority to designated officers of the Company or of its
wholly owned Subsidiaries to execute such requests for the Issuance under this
subsection or the amendment under subsection 3.02(c) of Letters of Credit to be
issued in the name of the Company or such Subsidiaries but for the account of
the Company pursuant to Article III of this Agreement.  In addition, if the
Letter of Credit being requested is to be issued in support of the performance
of financial obligations, the request for its Issuance must also include a
certification that the Letter of Credit is a financial Letter of Credit and
that the total of all such financial Letters of Credit outstanding plus the
requested financial Letter of Credit does not exceed the Dollar Equivalent
amount of $5,000,000.  The Agent will promptly notify the Banks upon the
issuance of a Letter of Credit.

                 (b)      At least two Business Days prior to the Issuance of
any Letter of Credit (or if the Issuing Bank has agreed to a shorter notice
period than two Business Days promptly upon receipt of the L/C Application or
L/C Amendment), the Issuing Bank will confirm with the Agent (by telephone or
in writing) that the Agent has received a copy of the L/C Application or L/C
Amendment Application from the Company and, if not, the Issuing Bank will
provide the Agent with a copy thereof.  Unless the Issuing Bank has received
notice from the Agent (A) directing the Issuing Bank not to Issue such Letter
of Credit because such Issuance is not then permitted under subsection 3.01(a)
as a result of the limitations set forth in clauses (1) through (3) thereof or
subsection 3.01(b)(ii); or (B) that one or more conditions specified in Article
V are not then satisfied; then, subject to the terms and conditions hereof, the
Issuing Bank shall, on the requested date, Issue a Letter of Credit for the
account of the Company in accordance with the Issuing Bank's usual and
customary business practices.

                 (c)      From time to time while a Letter of Credit is
outstanding and prior to the Revolving Termination Date, the Issuing Bank will,
upon the written request of the Company received by the Issuing Bank (with a
copy sent by the Company to the Agent) at





                                       35
<PAGE>   43
least four days (or such shorter time as the Issuing Bank may agree in a
particular instance in its sole discretion) prior to the proposed date of
amendment, amend any Letter of Credit issued by it.  Each such request for
amendment of a Letter of Credit shall be made by facsimile, confirmed
immediately in an original writing, made in the form of an L/C Amendment
Application and shall specify in form and detail satisfactory to the Issuing
Bank:  (i) the Letter of Credit to be amended; (ii) the nature of the proposed
amendment; and (iii) such other matters as the Issuing Bank may require.  The
Issuing Bank shall be under no obligation to amend any Letter of Credit if:
(A) the Issuing Bank would have no obligation at such time to issue such Letter
of Credit in its amended form under the terms of this Agreement; or (B) the
beneficiary of any such letter of Credit does not accept the proposed amendment
to the Letter of Credit.  The Agent will promptly notify the Banks of the
amendment of a Letter of Credit.

                 (d)      The Issuing Bank and the Banks agree that, while a
Letter of Credit is outstanding and prior to the Revolving Termination Date,
unless the Company delivers to the Issuing Bank a written request not to renew
a Letter of Credit (with a copy sent by the Company to the Agent) at least five
days (or such shorter time as the Issuing Bank may agree in a particular
instance in its sole discretion) prior to the scheduled date of notification of
nonrenewal, the Issuing Bank shall be entitled to authorize the automatic
renewal of any Letter of Credit issued by it.  Each such request not to renew a
Letter of Credit shall be made by facsimile, confirmed immediately in an
original writing, in the form of an L/C Amendment Application, and shall
specify in form and detail satisfactory to the Issuing Bank: (i) the Letter of
Credit not to be renewed; (ii) the expiry date of the Letter of Credit; and
(iii) such other matters as the Issuing Bank may require.  The Issuing Bank
shall be under no obligation so to renew any Letter of Credit if: (A) the
Issuing Bank would have no obligation at such time to issue or amend such
Letter of Credit in its renewed form under the terms of this Agreement; or (B)
the beneficiary of any such Letter of Credit does not accept the proposed
renewal of the Letter of Credit.  If any outstanding Letter of Credit shall
provide that it shall be automatically renewed unless the beneficiary thereof
receives notice from the Issuing Bank that such Letter of Credit shall not be
renewed, and if at the time of renewal the Issuing Bank would be entitled to
authorize the automatic renewal of such Letter of Credit in accordance with
this subsection 3.02(e) upon the request of the Company but the Issuing Bank
shall not have received any L/C Amendment Application from the Company with
respect to such renewal or other written direction by the Company with respect
thereto, the Issuing Bank shall nonetheless be permitted to allow such Letter
of Credit to renew, and the Company and the Banks hereby authorize such
renewal, and, accordingly, the Issuing Bank shall be deemed to have received an
L/C Amendment Application from the Company requesting such renewal.

                 (e)      The Issuing Bank may, at its election (or as required
by the Agent at the direction of the Majority Banks), deliver any notices of
termination or other communications to any Letter of Credit beneficiary or
transferee, and take any other action as necessary or appropriate, at any time
and from time to time, in order to cause the expiry date of such Letter of
Credit to be a date not later than the Revolving Termination Date.

                 (f)      This Agreement shall control in the event of any
conflict with any L/C-Related Document (other than any Letter of Credit).





                                       36
<PAGE>   44
                 (g)      The Issuing Bank will also deliver to the Agent,
concurrently or promptly following its delivery of a Letter of Credit, or
amendment to or renewal of a Letter of Credit, to an advising bank or a
beneficiary, a true and complete copy of each such Letter of Credit or
amendment of a Letter of Credit.

         3.03    Existing BofA Letters of Credit; Risk Participations, Drawings
and Reimbursements.

                 (a)      On and after the Closing Date, those letters of
credit issued by BofA for the account of the Company which are listed in
Schedule 3.03 (the "Existing BofA Letters of Credit") shall be deemed for all
purposes, including for purposes of the fees to be collected pursuant to
subsections 3.08(a) and 3.08(c), and reimbursement of costs and expenses to the
extent provided herein, Letters of Credit outstanding under this Agreement and
entitled to the benefits of this Agreement and the other Loan Documents, and
shall be governed by the applications and agreements pertaining thereto and by
this Agreement.  Each Bank shall be deemed to, and hereby irrevocably and
unconditionally agrees to, purchase from the Issuing Bank on the Closing Date a
participation in each such Letter of Credit and each drawing thereunder in an
amount equal to the product of (i) such Bank's Pro Rata Share times (ii) the
maximum amount available to be drawn under such Letter of Credit and the amount
of such drawing, respectively.  For purposes of Section 2.01 and subsection
2.10(b), the Existing BofA Letters of Credit shall be deemed to utilize pro
rata the Commitment of each Bank.

                 (b)      Immediately upon the Issuance of each Letter of
Credit in addition to those described in subsection 3.03(a), each Bank shall be
deemed to, and hereby irrevocably and unconditionally agrees to, purchase from
the Issuing Bank a participation in such Letter of Credit and each drawing
thereunder in an amount equal to the product of (i) the Pro Rata Share of such
Bank, times (ii) the maximum amount available to be drawn under such Letter of
Credit and the amount of such drawing, respectively.  For purposes of Section
2.01, each Issuance of a Letter of Credit shall be deemed to utilize the
Commitment of each Bank by an amount equal to the amount of such participation.

                 (c)      "Upon the receipt of any request for a drawing under
a Letter of Credit by the beneficiary or transferee thereof, the Issuing Bank
will promptly notify the Company.  Immediately upon reaching a determination
that it will pay a drawing under a Letter of Credit and, in the case of a
Letter of Credit denominated in an Offshore Currency, upon also determining the
Dollar Equivalent amount of the drawing, the Issuing Bank shall notify the
Company and the Agent of (i) its determination to pay the drawing, (ii) the
date the drawing will be paid (the "Honor Date"), (iii) the Dollar Equivalent
amount of the drawing, and (iv) in the case of a Letter of Credit denominated
in an Offshore Currency, the amount to be paid in the Offshore Currency.  The
Issuing Bank will endeavor to provide such notice at least one Business Day
prior to the Honor Date, but the delivery of such notice shall neither be a
condition to the payment of the drawing nor to the Company's obligation to
reimburse the amount paid on the Honor Date.  The Company shall reimburse the
Issuing Bank in Dollars in Same Day Funds no later than 10:00 a.m. (San
Francisco time) on the Honor Date, the Dollar Equivalent amount equal to the
amount so to be paid by the Issuing Bank.  In the event the





                                       37
<PAGE>   45
Company fails to reimburse the Issuing Bank in Same Day Funds for the full
Dollar Equivalent amount of any drawing under any Letter of Credit by 10:00
a.m. (San Francisco time) on the Honor Date, the Issuing Bank will promptly
notify the Agent and the Agent will promptly notify each Bank thereof, and the
Company shall be deemed to have requested that Base Rate Loans in the Dollar
Equivalent amount equal to the amount to be reimbursed on the Honor Date, which
Base Rate Loans shall be made by the Banks to be disbursed on the Honor Date
under such Letter of Credit, subject to the amount of the unutilized portion of
the Revolving Commitment and subject to the conditions set forth in Section
5.02.  The Issuing Bank shall be authorized to apply the proceeds of such Base
Rate Loans to the purchase of funds in the Applicable Currency to pay each
drawing due to be paid on the Honor Date.  Any notice given by the Issuing Bank
or the Agent pursuant to this subsection 3.03(c) may be oral if immediately
confirmed in writing (including by facsimile); provided that the lack of such
an immediate confirmation shall not affect the conclusiveness or binding effect
of such notice."

                 (d)      Each Bank shall upon any notice pursuant to
subsection 3.03(c) make available to the Agent for the account of the Issuing
Bank an amount in Dollars and in immediately available funds equal to its Pro
Rata Share of the amount of the drawing, whereupon the participating Banks
shall (subject to subsection 3.03(e)) each be deemed to have made a Revolving
Loan consisting of a Base Rate Loan to the Company in that amount.  If any Bank
so notified fails to make available to the Agent for the account of the Issuing
Bank the amount of such Bank's Pro Rata Share of the amount of the drawing by
no later than 12:00 noon (San Francisco time) on the Honor Date, then interest
shall accrue on such Bank's obligation to make such payment, from the Honor
Date to the date such Bank makes such payment, at a rate per annum equal to the
Federal Funds Rate in effect from time to time during such period.  The Agent
will promptly give notice of the occurrence of the Honor Date, but failure of
the Agent to give any such notice on the Honor Date or in sufficient time to
enable any Bank to effect such payment on such date shall not relieve such Bank
from its obligations under this Section 3.03.

                 (e)      With respect to any unreimbursed drawing that is not
converted into Revolving Loans consisting of Base Rate Loans to the Company in
whole or in part, because of the Company's failure to satisfy the conditions
set forth in Section 5.02 or for any other reason, the Company shall be deemed
to have incurred from the Issuing Bank an L/C Borrowing denominated in Dollars
in the Dollar Equivalent amount of such drawing as determined by the Issuing
Bank, which L/C Borrowing shall be due and payable on demand (together with
interest) and shall bear interest at a rate per annum equal to the Base Rate
plus 2% per annum, and each Bank's payment to the Issuing Bank pursuant to
subsection 3.03(d) shall be deemed payment in respect of its participation in
such L/C Borrowing and shall constitute an L/C Advance from such Bank in
satisfaction of its participation obligation under this Section 3.03.

                 (f)      Each Bank's obligation in accordance with this
Agreement to make the Revolving Loans or L/C Advances, as contemplated by this
Section 3.03, as a result of a drawing under a Letter of Credit, shall be
absolute and unconditional and without recourse to the Issuing Bank and shall
not be affected by any circumstance, including (i) any set-off,





                                       38
<PAGE>   46
counterclaim, recoupment, defense or other right which such Bank may have
against the Issuing Bank, the Company or any other Person for any reason
whatsoever; (ii) the occurrence or continuance of a Default, an Event of
Default or a Material Adverse Effect; or (iii) any other circumstance,
happening or event whatsoever, whether or not similar to any of the foregoing;
provided, however, that each Bank's obligation to make Revolving Loans under
this Section 3.03 is subject to the conditions set forth in Section 5.02.

         3.04    Repayment of Participations.

                 (a)      Upon (and only upon) receipt by the Agent for the
account of the Issuing Bank of immediately available funds from the Company (i)
in reimbursement of any payment made by the Issuing Bank under the Letter of
Credit with respect to which any Bank has paid the Agent for the account of the
Issuing Bank for such Bank's participation in the Letter of Credit pursuant to
Section 3.03 or (ii) in payment of interest thereon, the Agent will pay to each
Bank, in the same funds as those received by the Agent for the account of the
Issuing Bank, the amount of such Bank's Pro Rata Share of such funds, and the
Issuing Bank shall receive the amount of the Pro Rata Share of such funds of
any Bank that did not so pay the Agent for the account of the Issuing Bank.

                 (b)      If the Agent or the Issuing Bank is required at any
time to return to the Company, or to a trustee, receiver, liquidator,
custodian, or any official in any Insolvency Proceeding, any portion of the
payments made by the Company to the Agent for the account of the Issuing Bank
pursuant to subsection 3.04(a) in reimbursement of a payment made under the
Letter of Credit or interest or fee thereon, each Bank shall, on demand of the
Agent, forthwith return to the Agent or the Issuing Bank the amount of its Pro
Rata Share of any amounts so returned by the Agent or the Issuing Bank plus
interest thereon from the date such demand is made to the date such amounts are
returned by such Bank to the Agent or the Issuing Bank, at a rate per annum
equal to the Federal Funds Rate in effect from time to time.

         3.05    Role of the Issuing Bank.

                 (a)      Each Bank and the Company agree that, in paying any
drawing under a Letter of Credit, the Issuing Bank shall not have any
responsibility to obtain any document (other than any sight draft and
certificates expressly required by the Letter of Credit) or to ascertain or
inquire as to the validity or accuracy of any such document or the authority of
the Person executing or delivering any such document.

                 (b)      No Agent-Related Person nor any of the respective
correspondents, participants or assignees of the Issuing Bank shall be liable
to any Bank for: (i) any action taken or omitted in connection herewith at the
request or with the approval of the Banks (including the Majority Banks, as
applicable); (ii) any action taken or omitted in the absence of gross
negligence or willful misconduct; or (iii) the due execution, effectiveness,
validity or enforceability of any L/C-Related Document.





                                       39
<PAGE>   47
                 (c)      The Company hereby assumes all risks of the acts or
omissions of any beneficiary or transferee with respect to its use of any
Letter of Credit; provided, however, that this assumption is not intended to,
and shall not, preclude the Company's pursuing such rights and remedies as it
may have against the beneficiary or transferee at law or under any other
agreement.  No Agent-Related Person, nor any of the respective correspondents,
participants or assignees of the Issuing Bank, shall be liable or responsible
for any of the matters described in clauses (i) through (vii) of Section 3.06;
provided, however, anything in such clauses to the contrary notwithstanding,
that the Company may have a claim against the Issuing Bank, and the Issuing
Bank may be liable to the Company, to the extent, but only to the extent, of
any direct, as opposed to consequential or exemplary, damages suffered by the
Company which the Company proves were caused by the Issuing Bank's willful
misconduct or gross negligence or the Issuing Bank's willful failure to pay
under any Letter of Credit after the presentation to it by the beneficiary of a
sight draft and certificate(s) strictly complying with the terms and conditions
of a Letter of Credit.  In furtherance and not in limitation of the foregoing:
(i) the Issuing Bank may accept documents that appear on their face to be in
order, without responsibility for further investigation, regardless of any
notice or information to the contrary; and (ii) the Issuing Bank shall not be
responsible for the validity or sufficiency of any instrument transferring or
assigning or purporting to transfer or assign a Letter of Credit or the rights
or benefits thereunder or proceeds thereof, in whole or in part, which may
prove to be invalid or ineffective for any reason.

         3.06    Obligations Absolute.  The obligations of the Company under
this Agreement and any L/C-Related Document to reimburse the Issuing Bank for a
drawing under a Letter of Credit, and to repay any L/C Borrowing and any
drawing under a Letter of Credit converted into Revolving Loans, shall be
unconditional and irrevocable, and shall be paid strictly in accordance with
the terms of this Agreement and each such other L/C-Related Document under all
circumstances, including the following:  (i) any lack of validity or
enforceability of this Agreement or any L/C-Related Document; (ii) any change
in the time, manner or place of payment of, or in any other term of, all or any
of the obligations of the Company in respect of any Letter of Credit or any
other amendment or waiver of or any consent to departure from all or any of the
L/C- Related Documents; (iii) the existence of any claim, set-off, defense or
other right that the Company may have at any time against any beneficiary or
any transferee of any Letter of Credit (or any Person for whom any such
beneficiary or any such transferee may be acting), the Issuing Bank or any
other Person, whether in connection with this Agreement, the transactions
contemplated hereby or by the L/C-Related Documents or any unrelated
transaction; (iv) any draft, demand, certificate or other document presented
under any Letter of Credit proving to be forged, fraudulent, invalid or
insufficient in any respect or any statement therein being untrue or inaccurate
in any respect; or any loss or delay in the transmission or otherwise of any
document required in order to make a drawing under any Letter of Credit; (v)
any payment by the Issuing Bank under any Letter of Credit against presentation
of a draft or certificate that does not strictly comply with the terms of any
Letter of Credit; or any payment made by the Issuing Bank under any Letter of
Credit to any Person purporting to be a trustee in bankruptcy,
debtor-in-possession, assignee for the benefit of creditors, liquidator,
receiver or other representative of or successor to any beneficiary or any
transferee of any Letter of Credit, including any arising in connection with
any Insolvency





                                       40
<PAGE>   48
Proceeding; (vi) any exchange, release or non-perfection of any collateral, or
any release or amendment or waiver of or consent to departure from any other
guarantee, for all or any of the obligations of the Company in respect of any
Letter of Credit; or (vii) any circumstance that might otherwise constitute a
defense available to, or a discharge of, the Company or a guarantor.

         3.07    Cash Collateral Pledge.  (i) Upon the request of the Agent,
(A) if the Issuing Bank has honored any full or partial drawing request on any
Letter of Credit and such drawing has resulted in an L/C Borrowing hereunder,
or (B) if, as of 10 days prior to the Revolving Termination Date or at any time
during such 10-day period or on or at any time after the Revolving Termination
Date, any Letters of Credit may for any reason remain outstanding and partially
or wholly undrawn, or (ii) the occurrence of the circumstances described in
subsection 2.07 requiring the Company to Cash Collateralize Letters of Credit,
then, the Company shall immediately Cash Collateralize the L/C Obligations in
an amount equal to such L/C Obligations.  The Company hereby grants the Agent,
for the benefit of the Agent, the Issuing Bank and the Banks, a security
interest in all such cash and deposit account balances.  Cash collateral shall
be maintained in blocked, non-interest bearing deposit accounts at BofA.  After
the Revolving Termination Date the Issuing Bank may exercise a right of set-off
with respect to any cash collateral it holds and may use such funds to satisfy
drawings under Letters of Credit.

         3.08    Letter of Credit Fees.

                 (a)      The Company shall pay to the Agent for the account of
each of the Banks a letter of credit fee with respect to the Letters of Credit
equal to the percentage rate per annum specified in the table in subsection
2.10(c) of the average daily maximum Dollar Equivalent amount available to be
drawn of the outstanding Letters of Credit, computed on a quarterly basis in
arrears on the last Business Day of each calendar quarter based upon Letters of
Credit outstanding for that quarter as calculated by the Agent; provided
however that the Dollar Equivalent amount of any such Letters of Credit which
are denominated in any Offshore Currency shall be determined based upon the
Spot Rate for the purchase of such Offshore Currency with Dollars at Issuance
and as of the last Business Day of each month for the quarter in question.
Such letter of credit fees shall be due and payable quarterly in arrears on the
last Business Day of each calendar quarter during which Letters of Credit are
outstanding, commencing on the first such quarterly date to occur after the
Closing Date, through the Revolving Termination Date (or such later date upon
which the outstanding Letters of Credit shall expire), with the final payment
to be made on the Revolving Termination Date (or such later expiration date).

                 (b)      The Company shall pay to the Issuing Bank, for its
account, a letter of credit fronting fee for each Letter of Credit Issued by
the Issuing Bank equal to that percentage of the Dollar Equivalent face amount
(or increased face amount, as the case may be) of such Letter of Credit
specified in the Fee Letter.  Such Letter of Credit fronting fee shall be due
and payable on each date of Issuance of a Letter of Credit.





                                       41
<PAGE>   49
                 (c)      The Company shall pay to the Issuing Bank from time
to time on demand the normal presentation, amendment and other processing fees,
and other standard costs and charges, of the Issuing Bank relating to letters
of credit as from time to time in effect.

         3.09    Uniform Customs and Practice.  The Uniform Customs and
Practice for Documentary Credits as published by the International Chamber of
Commerce most recently at the time of issuance of any Letter of Credit shall
(unless otherwise expressly provided in the Letters of Credit) apply to the
Letters of Credit.

         3.10    Letters of Credit Denominated in Offshore Currencies.

                 (a)      The Agent will determine the Dollar Equivalent amount
with respect to any (i) Letter of Credit denominated in an Offshore Currency as
of the date of Issuance, (ii) outstanding L/C Obligations from time to time as
necessary to compute availability under the L/C Commitment, the Commitments,
and (iii) other amount necessary for the administration of this Agreement (each
such date under clauses (i) through (iii) a "Computation Date").  Each
determination of a Dollar Equivalent amount by the Agent shall be conclusive
and binding on the Company and the Banks in the absence of manifest error.

                 (b)      Subject to Section 4.04, if on any Computation Date
the Agent shall have determined that, due to a change in applicable rates of
exchange between Dollars and Offshore Currencies, either (a) the Effective
Amount of all L/C Obligations exceeds the lower of:  (i) the L/C Commitment,
and (ii) the Aggregate Borrowing Base, or (b) the aggregate Dollar Equivalent
principal amount of all Loans and L/C Obligations then outstanding exceeds the
lower of:  (i) the combined Commitments of the Banks, and (ii) the Aggregate
Borrowing Base, then the Agent shall give notice to the Company which states
the Dollar Equivalent amount of any such excess and requires the Company to
Cash Collateralize or to make such mandatory prepayments as required by Section
2.07.


                                   ARTICLE IV

                     TAXES, YIELD PROTECTION AND ILLEGALITY

         4.01    Taxes.

                 (a)      Any and all payments by the Company to each Bank or
the Agent under this Agreement and any other Loan Document shall be made free
and clear of, and without deduction or withholding for, any Taxes.  In
addition, the Company shall pay all Other Taxes.

                 (b)      If the Company shall be required by law to deduct or
withhold any Taxes, Other Taxes or Further Taxes from or in respect of any sum
payable hereunder to any Bank or the Agent, then:  (i) the sum payable shall be
increased as necessary so that, after making all required deductions and
withholdings (including deductions and withholdings





                                       42
<PAGE>   50
applicable to additional sums payable under this Section), such Bank or the
Agent, as the case may be, receives and retains an amount equal to the sum it
would have received and retained had no such deductions or withholdings been
made; (ii) the Company shall make such deductions and withholdings; (iii) the
Company shall pay the full amount deducted or withheld to the relevant taxing
authority or other authority in accordance with applicable law; and (iv) the
Company shall also pay to each Bank or the Agent for the account of such Bank
at the time interest is paid, Further Taxes in the amount that the respective
Bank specifies as necessary to preserve the after-tax yield the Bank would have
received if such Taxes, Other Taxes or Further Taxes had not been imposed.

                 (c)      The Company agrees to indemnify and hold harmless
each Bank and the Agent for the full amount of i) Taxes, ii) Other Taxes, and
iii) Further Taxes in the amount that the respective Bank specifies as
necessary to preserve the after-tax yield the Bank would have received if such
Taxes, Other Taxes or Further Taxes had not been imposed, and any liability
(including penalties, interest, additions to tax and expenses) arising
therefrom or with respect thereto, whether or not such Taxes, Other Taxes or
Further Taxes were correctly or legally asserted.  Payment under this
indemnification shall be made within 30 days after the date the Bank or the
Agent makes written demand therefor.

                 (d)      Within 30 days after the date of any payment by the
Company of Taxes, Other Taxes or Further Taxes, the Company shall furnish to
each Bank or the Agent the original or a certified copy of a receipt evidencing
payment thereof, or other evidence of payment satisfactory to such Bank or the
Agent.

                 (e)      If the Company is required to pay any amount to any
Bank or the Agent pursuant to subsection (b) or (c) of this Section, then such
Bank or Agent shall use reasonable efforts (consistent with legal and
regulatory restrictions) to change the jurisdiction of its Lending Office or
take such reasonable action consistent with applicable regulatory requirements
so as to eliminate any such additional payment by the Company which may
thereafter accrue, if such change in the sole judgment of such Bank or Agent is
not otherwise disadvantageous to such Bank or Agent.

         4.02    Illegality.

                 (a)      If any Bank determines that the introduction of any
Requirement of Law, or any change in any Requirement of Law, or in the
interpretation or administration of any Requirement of Law, has made it
unlawful, or that any central bank or other Governmental Authority has asserted
that it is unlawful, for any Bank or its applicable Lending Office to make
Offshore Rate Loans, then, on notice thereof by the Bank to the Company through
the Agent, any obligation of that Bank to make Offshore Rate Loans shall be
suspended until the Bank notifies the Agent and the Company that the
circumstances giving rise to such determination no longer exist.

                 (b)      If a Bank determines that it is unlawful to maintain
any Offshore Rate Loan, the Company shall, upon its receipt of notice of such
fact and demand from such Bank





                                       43
<PAGE>   51
(with a copy to the Agent), prepay in full such Offshore Rate Loans of that
Bank then outstanding, together with interest and Utilization Fees accrued
thereon and amounts required under Section 4.04, either on the last day of the
Interest Period thereof, if the Bank may lawfully continue to maintain such
Offshore Rate Loans to such day, or immediately, if the Bank may not lawfully
continue to maintain such Offshore Rate Loan.  If the Company is required to so
prepay any Offshore Rate Loan, then concurrently with such prepayment, the
Company shall borrow from the affected Bank, in the amount of such repayment, a
Base Rate Loan.

                 (c)      Before giving any notice to the Agent under this
Section, the affected Bank shall designate a different Lending Office with
respect to its Offshore Rate Loans if such designation will avoid the need for
giving such notice or making such demand and will not, in the judgment of the
Bank, be illegal or otherwise disadvantageous to the Bank.

         4.03    Increased Costs and Reduction of Return.

                 (a)      If any Bank determines that, due to either (i) the
introduction of or any change in or in the interpretation of any law or
regulation or (ii) the compliance by that Bank with any guideline or request
from any central bank or other Governmental Authority (whether or not having
the force of law), there shall be any increase in the cost to such Bank of
agreeing to make or making, funding or maintaining any Offshore Rate Loans or
participating in Letters of Credit, or, in the case of the Issuing Bank, any
increase in the cost to the Issuing Bank of agreeing to issue, issuing or
maintaining any Letter of Credit or of agreeing to make or making, funding or
maintaining any unpaid drawing under any Letter of Credit, then the Company
shall be liable for, and shall from time to time, upon demand (with a copy of
such demand to be sent to the Agent), pay to the Agent for the account of such
Bank, additional amounts as are sufficient to compensate such Bank for such
increased costs.

                 (b)      If any Bank shall have determined that (i) the
introduction of any Capital Adequacy Regulation, (ii) any change in any Capital
Adequacy Regulation, (iii) any change in the interpretation or administration
of any Capital Adequacy Regulation by any central bank or other Governmental
Authority charged with the interpretation or administration thereof, or (iv)
compliance by the Bank (or its Lending Office) or any corporation controlling
the Bank with any Capital Adequacy Regulation, affects or would affect the
amount of capital required or expected to be maintained by the Bank or any
corporation controlling the Bank and (taking into consideration such Bank's or
such corporation's policies with respect to capital adequacy and such Bank's
desired return on capital) determines that the amount of such capital is
increased as a consequence of its Commitment, loans, credits or obligations
under this Agreement, then, upon demand of such Bank to the Company through the
Agent, the Company shall pay to the Bank, from time to time as specified by the
Bank, additional amounts sufficient to compensate the Bank for such increase.

         4.04    Funding Losses.  The Company shall reimburse each Bank and
hold each Bank harmless from any loss or expense which the Bank may sustain or
incur as a consequence of:





                                       44
<PAGE>   52
                 (a)      the failure of the Company to make on a timely basis
any payment of principal of any Offshore Rate Loan;

                 (b)      the failure of the Company to borrow, continue or
convert a Loan after the Company has given (or is deemed to have given) a
Notice of Borrowing or a Notice of Conversion/Continuation;

                 (c)      the failure of the Company to make any prepayment in
accordance with any notice delivered under Section 2.06;

                 (d)      the prepayment (including pursuant to Section 2.06 or
Section 2.07) or other payment (including after acceleration thereof) of an
Offshore Rate Loan on a day that is not the last day of the relevant Interest
Period; or

                 (e)      the automatic conversion under Section 2.04 of any
Offshore Rate Loan to a Base Rate Loan on a day that is not the last day of the
relevant Interest Period;

including any such loss or expense arising from the liquidation or reemployment
of funds obtained by it to maintain its Offshore Rate Loans or from fees
payable to terminate the deposits from which such funds were obtained.  For
purposes of calculating amounts payable by the Company to the Banks under this
Section and under subsection 4.03(a), each Offshore Rate Loan made by a Bank
(and each related reserve, special deposit or similar requirement) shall be
conclusively deemed to have been funded at the IBOR used in determining the
Offshore Rate for such Offshore Rate Loan by a matching deposit or other
borrowing in the interbank eurodollar market for a comparable amount and for a
comparable period, whether or not such Offshore Rate Loan is in fact so funded.

         4.05    Inability to Determine Rates.  If the Agent determines that
for any reason adequate and reasonable means do not exist for determining the
Offshore Rate for any requested Interest Period with respect to a proposed
Offshore Rate Loan, or that the Offshore Rate applicable pursuant to subsection
2.09(a) for any requested Interest Period with respect to a proposed Offshore
Rate Loan does not adequately and fairly reflect the cost to the Banks of
funding such Loan, the Agent will promptly so notify the Company and each Bank.
Thereafter, the obligation of the Banks to make or maintain Offshore Rate Loans
hereunder shall be suspended until the Agent revokes such notice in writing.
Upon receipt of such notice, the Company may revoke any Notice of Borrowing or
Notice of Conversion/Continuation then submitted by it.  If the Company does
not revoke such Notice, the Banks shall make, convert or continue the Loans, as
proposed by the Company, in the amount specified in the applicable notice
submitted by the Company, but such Loans shall be made, converted or continued
as Base Rate Loans instead of Offshore Rate Loans.

         4.06    Reserves on Offshore Rate Loans.  The Company shall pay to
each Bank, as long as such Bank shall be required under regulations of the FRB
to maintain reserves with respect to liabilities or assets consisting of or
including Eurocurrency funds or deposits (currently known as "Eurocurrency
liabilities"), additional costs on the unpaid principal





                                       45
<PAGE>   53
amount of each Offshore Rate Loan equal to the actual costs of such reserves
allocated to such Loan by the Bank (as determined by the Bank in good faith,
which determination shall be conclusive), payable on each date on which
interest is payable on such Loan, provided the Company shall have received at
least 15 days' prior written notice (with a copy to the Agent) of such
additional interest from the Bank.  If a Bank fails to give notice 15 days
prior to the relevant Interest Payment Date, such additional interest shall be
payable 15 days from receipt of such notice.

         4.07    Certificates of Banks.  Any Bank claiming reimbursement or
compensation under this Article IV shall deliver to the Company (with a copy to
the Agent) a certificate setting forth in reasonable detail the amount payable
to the Bank hereunder and such certificate shall be conclusive and binding on
the Company in the absence of manifest error.

         4.08    Survival.  The agreements and obligations of the Company in
this Article IV shall survive the payment of all other Obligations.


                                   ARTICLE V

                                   ARTICLE VI

         6.18    Swap Obligations.  Neither the Company nor any of its
Subsidiaries has incurred any outstanding obligations under any Rate Contracts,
other than Permitted Swap Obligations.  The Company has undertaken its own
independent assessment of its consolidated





                                       53

                 (a)      The provisions of each of the Collateral Documents
are effective to create in favor of the Agent, for the benefit of the Banks, a
legal, valid and enforceable, and, subject to Permitted Liens, first priority
security interest in all right, title and interest of the Company and the
Guarantors in the collateral described therein.

                 (b)      All representations and warranties of the Company and

associated with review and following up on the report shall be borne solely by

make any prepayment (whether by reason of acceleration thereof or otherwise) of
any principal of or premium on, or in respect of the redemption, retirement,
purchase or other acquisition of any Approved Subordinated Indebtedness.

Obligation; or (B) fails to perform or observe any other condition or covenant,
or any other event shall occur or condition exist, under any agreement or
instrument relating to any such Indebtedness or Contingent Obligation; if the
effect of such failure, event or condition described in (A) or (B), above, is

appointment of a receiver, trustee, custodian, conservator, liquidator,
mortgagee in possession (or agent therefor), or other similar Person for itself
or a substantial portion of its property or business; or

                 (h)      ERISA.  (i) An ERISA Event shall occur with respect

contests





                                       70
<PAGE>   78
in any manner the validity or enforceability thereof or denies that it has any
further liability or obligation thereunder.

         9.02    Remedies.  If any Event of Default occurs, the Agent shall, at
the request of, or may, with the consent of, the Majority Banks,

                 (a)      declare the commitment of each Bank to make Loans and
any obligation of the Issuing Bank to Issue Letters of Credit to be terminated,
whereupon such commitments and obligation shall be terminated;

                 (b)      declare an amount equal to the maximum aggregate
amount that is or at any time thereafter may become available for drawing under
any outstanding Letters of Credit (whether or not any beneficiary shall have
presented, or shall be entitled at such time to present, the drafts or other
documents required to draw under such Letters of Credit) to be immediately due
and payable, and declare the unpaid principal amount of all outstanding Loans,
all interest accrued and unpaid thereon, and all other amounts owing or payable
hereunder or under any other Loan Document to be immediately due and payable,
without presentment, demand, protest or other notice of any kind, all of which
are hereby expressly waived by the Company; and

                 (c)      exercise on behalf of itself and the Banks all rights
and remedies available to it and the Banks under the Loan Documents or
applicable law;

provided, however, that upon the occurrence of any event specified in
subsection (f) or (g) of Section 9.01 (in the case of clause (i) of subsection
(g) upon the expiration of the 60-day period mentioned therein), the obligation
of each Bank to make Loans and any obligation of the Issuing Bank to Issue
Letters of Credit shall automatically terminate and the unpaid principal amount
of all outstanding Loans and all interest and other amounts as aforesaid shall
automatically become due and payable without further act of the Agent, the
Issuing Bank or any Bank.

         9.03    Rights Not Exclusive.  The rights provided for in this
Agreement and the other Loan Documents are cumulative and are not exclusive of
any other rights, powers, privileges or remedies provided by law or in equity,
or under any other instrument, document or agreement now existing or hereafter
arising.


                                   ARTICLE X

                                   THE AGENT





                                       71
<PAGE>   79
         10.01   Appointment and Authorization; "Agent".

                 (a)      Each Bank hereby irrevocably (subject to Section
10.09) appoints, designates and authorizes the Agent to take such action on its
behalf under the provisions of this Agreement and each other Loan Document and
to exercise such powers and perform such duties as are expressly delegated to
it by the terms of this Agreement or any other Loan Document, together with
such powers as are reasonably incidental thereto.  Notwithstanding any
provision to the contrary contained elsewhere in this Agreement or in any other
Loan Document, the Agent shall not have any duties or responsibilities, except
those expressly set forth herein, nor shall the Agent have or be deemed to have
any fiduciary relationship with any Bank, and no implied covenants, functions,
responsibilities, duties, obligations or liabilities shall be read into this
Agreement or any other Loan Document or otherwise exist against the Agent.
Without limiting the generality of the foregoing sentence, the use of the term
"agent" in this Agreement with reference to the Agent is not intended to
connote any fiduciary or other implied (or express) obligations arising under
agency doctrine of any applicable law.  Instead, such term is used merely as a
matter of market custom, and is intended to create or reflect only an
administrative relationship between independent contracting parties.

                 (b)      The Issuing Bank shall act on behalf of the Banks
with respect to any Letters of Credit Issued by it and the documents associated
therewith until such time and except for so long as the Agent may agree at the
request of the Majority Lenders to act for such Issuing Bank with respect
thereto; provided, however, that the Issuing Bank shall have all of the
benefits and immunities (i) provided to the Agent in this Article X with
respect to any acts taken or omissions suffered by the Issuing Bank in
connection with Letters of Credit Issued by it or proposed to be Issued by it
and the application and agreements for letters of credit pertaining to the
Letters of Credit as fully as if the term "Agent," as used in this Article X,
included the Issuing Bank with respect to such acts or omissions, and (ii) as
additionally provided in this Agreement with respect to the Issuing Bank.

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

         10.03   Liability of Agent.  None of the Agent-Related Persons shall
(i) be liable for any action taken or omitted to be taken by any of them under
or in connection with this Agreement or any other Loan Document or the
transactions contemplated hereby (except for its own gross negligence or
willful misconduct), or (ii) be responsible in any manner to any of the Banks
for any recital, statement, representation or warranty made by the Company or
any Subsidiary or Affiliate of the Company, or any officer thereof, contained
in this Agreement or in any other Loan Document, or in any certificate, report,
statement or other document





                                       72
<PAGE>   80
referred to or provided for in, or received by the Agent under or in connection
with, this Agreement or any other Loan Document or for the value of or title to
any Collateral, or the validity, effectiveness, genuineness, enforceability or
sufficiency of this Agreement or any other Loan Document, or for any failure of
the Company or any other party to any Loan Document to perform its obligations
hereunder or thereunder.  No Agent-Related Person shall be under any obligation
to any Bank to ascertain or to inquire as to the observance or performance of
any of the agreements contained in, or conditions of, this Agreement or any
other Loan Document, or to inspect the properties, books or records of the
Company or any of the Company's Subsidiaries or Affiliates.

         10.04   Reliance by Agent.

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

                 (b)      For purposes of determining compliance with the
conditions specified in Section 5.01, each Bank that has executed this
Agreement shall be deemed to have consented to, approved or accepted or to be
satisfied with, each document or other matter either sent by the Agent to such
Bank for consent, approval, acceptance or satisfaction, or required thereunder
to be consented to or approved by or acceptable or satisfactory to the Bank.

         10.05   Notice of Default.  The Agent shall not be deemed to have
knowledge or notice of the occurrence of any Default or Event of Default,
except with respect to defaults in the payment of principal, interest and fees
required to be paid to the Agent for the account of the Banks, unless the Agent
shall have received written notice from a Bank or the Company referring to this
Agreement, describing such Default or Event of Default and stating that such
notice is a "notice of default."  The Agent will notify the Banks of its
receipt of any such notice.  The Agent shall take such action with respect to
such Default or Event of Default as may be requested by the Majority Banks in
accordance with Article IX; provided, however, that unless and until the Agent
has received any such request, the Agent may (but shall not be





                                       73
<PAGE>   81
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 or in
the best interest of the Banks.

         10.06   Credit Decision.  Each Bank acknowledges that none of the
Agent-Related Persons has made any representation or warranty to it, and that
no act by the Agent hereinafter taken, including any review of the affairs of
the Company and its Subsidiaries, shall be deemed to constitute any
representation or warranty by any Agent-Related Person to any Bank.  Each Bank
represents to the Agent that it has, independently and without reliance upon
any Agent-Related Person and based on such documents and information as it has
deemed appropriate, made its own appraisal of and investigation into the
business, prospects, operations, property, financial and other condition and
creditworthiness of the Company and its Subsidiaries, the value of and title to
any Collateral, and all applicable bank regulatory laws relating to the
transactions contemplated hereby, and made its own decision to enter into this
Agreement and to extend credit to the Company hereunder.  Each Bank also
represents that it will, independently and without reliance upon any
Agent-Related Person and based on such documents and information as it shall
deem appropriate at the time, continue to make its own credit analysis,
appraisals and decisions in taking or not taking action under this Agreement
and the other Loan Documents, and to make such investigations as it deems
necessary to inform itself as to the business, prospects, operations, property,
financial and other condition and creditworthiness of the Company.  Except for
notices, reports and other documents expressly herein required to be furnished
to the Banks by the Agent, the Agent shall not have any duty or responsibility
to provide any Bank with any credit or other information concerning the
business, prospects, operations, property, financial and other condition or
creditworthiness of the Company which may come into the possession of any of
the Agent-Related Persons.

         10.07   Indemnification of Agent.  Whether or not the transactions
contemplated hereby are consummated, the Banks shall indemnify upon demand the
Agent-Related Persons (to the extent not reimbursed by or on behalf of the
Company and without limiting the obligation of the Company to do so), pro rata,
from and against any and all Indemnified Liabilities; provided, however, that
no Bank shall be liable for the payment to the Agent-Related Persons of any
portion of such Indemnified Liabilities resulting solely from such Person's
gross negligence or willful misconduct.  Without limitation of the foregoing,
each Bank shall reimburse the Agent upon demand for its ratable share of any
costs or out-of-pocket expenses (including Attorney Costs) incurred by the
Agent in connection with the preparation, execution, delivery, administration,
modification, amendment or enforcement (whether through negotiations, legal
proceedings or otherwise) of, or legal advice in respect of rights or
responsibilities under, this Agreement, any other Loan Document, or any
document contemplated by or referred to herein, to the extent that the Agent is
not reimbursed for such expenses by or on behalf of the Company.  The
undertaking in this Section shall survive the payment of all Obligations
hereunder and the resignation or replacement of the Agent.

         10.08   Agent in Individual Capacity.  BofA and its Affiliates may
make loans to, issue letters of credit for the account of, accept deposits
from, acquire equity interests in and





                                       74
<PAGE>   82
generally engage in any kind of banking, trust, financial advisory,
underwriting or other business with the Company and its Subsidiaries and
Affiliates as though BofA were not the Agent or the Issuing Bank hereunder and
without notice to or consent of the Banks.  The Banks acknowledge that,
pursuant to such activities, BofA or its Affiliates may receive information
regarding the Company or its Affiliates (including information that may be
subject to confidentiality obligations in favor of the Company or such
Affiliate) and acknowledge that the Agent shall be under no obligation to
provide such information to them.  With respect to its Loans, BofA shall have
the same rights and powers under this Agreement as any other Bank and may
exercise the same as though it were not the Agent or the Issuing Bank.

         10.09   Successor Agent.  The Agent may, and at the request of the
Majority Banks shall, resign as Agent upon 30 days' notice to the Banks.  If
the Agent resigns under this Agreement, the Majority Banks shall appoint from
among the Banks a successor agent for the Banks.  If no successor agent is
appointed prior to the effective date of the resignation of the Agent, the
Agent may appoint, after consulting with the Banks and the Company, a successor
agent from among the Banks.  Upon the acceptance of its appointment as
successor agent hereunder, such successor agent shall succeed to all the
rights, powers and duties of the retiring Agent and the term "Agent" shall mean
such successor agent and the retiring Agent's appointment, powers and duties as
Agent shall be terminated. After any retiring Agent's resignation hereunder as
Agent, the provisions of this Article X and Sections 11.04 and 11.05 shall
inure to its benefit as to any actions taken or omitted to be taken by it while
it was Agent under this Agreement.  If no successor agent has accepted
appointment as Agent by the date which is 30 days following a retiring Agent's
notice of resignation, the retiring Agent's resignation shall nevertheless
thereupon become effective and the Banks shall perform all of the duties of the
Agent hereunder until such time, if any, as the Majority Banks appoint a
successor agent as provided for above.  Notwithstanding the foregoing, however,
BofA may not be removed as the Agent at the request of the Majority Banks
unless BofA shall also simultaneously be replaced as "Issuing Bank" hereunder
pursuant to documentation in form and substance reasonably satisfactory to
BofA.

         10.10   Withholding Tax.

                 (a)      If any Bank is a "foreign corporation, partnership or
trust" within the meaning of the Code and such Bank claims exemption from, or a
reduction of, U.S. withholding tax under Sections 1441 or 1442 of the Code,
such Bank agrees with and in favor of the Agent, to deliver to the Agent:

                      (i)   if such Bank claims an exemption from, or a
         reduction of, withholding tax under a United States tax treaty, two
         properly completed and executed copies of IRS Form 1001 before the
         payment of any interest in the first calendar year and before the
         payment of any interest in each third succeeding calendar year during
         which interest may be paid under this Agreement;





                                       75
<PAGE>   83
                      (ii)  if such Bank claims that interest paid under this
         Agreement is exempt from United States withholding tax because it is
         effectively connected with a United States trade or business of such
         Bank, two properly completed and executed copies of IRS Form 4224
         before the payment of any interest is due in the first taxable year of
         such Bank and in each succeeding taxable year of such Bank during
         which interest may be paid under this Agreement; and

                    (iii)   such other form or forms as may be required under
         the Code or other laws of the United States as a condition to
         exemption from, or reduction of, United States withholding tax.

Such Bank agrees to promptly notify the Agent of any change in circumstances
which would modify or render invalid any claimed exemption or reduction.

                 (b)      If any Bank claims exemption from, or reduction of,
withholding tax under a United States tax treaty by providing IRS Form 1001 and
such Bank sells, assigns, grants a participation in, or otherwise transfers all
or part of the Obligations of the Company to such Bank, such Bank agrees to
notify the Agent of the percentage amount in which it is no longer the
beneficial owner of Obligations of the Company to such Bank.  To the extent of
such percentage amount, the Agent will treat such Bank's IRS Form 1001 as no
longer valid.

                 (c)      If any Bank claiming exemption from United States
withholding tax by filing IRS Form 4224 with the Agent sells, assigns, grants a
participation in, or otherwise transfers all or part of the Obligations of the
Company to such Bank, such Bank agrees to undertake sole responsibility for
complying with the withholding tax requirements imposed by Sections 1441 and
1442 of the Code.

                 (d)      If any Bank is entitled to a reduction in the
applicable withholding tax, the Agent may withhold from any interest payment to
such Bank an amount equivalent to the applicable withholding tax after taking
into account such reduction.  However, if the forms or other documentation
required by subsection (a) of this Section are not delivered to the Agent, then
the Agent may withhold from any interest payment to such Bank not providing
such forms or other documentation an amount equivalent to the applicable
withholding tax imposed by Sections 1441 and 1442 of the Code, without
reduction.

                 (e)      If the IRS or any other Governmental Authority of the
United States or other jurisdiction asserts a claim that the Agent did not
properly withhold tax from amounts paid to or for the account of any Bank
(because the appropriate form was not delivered or was not properly executed,
or because such Bank failed to notify the Agent of a change in circumstances
which rendered the exemption from, or reduction of, withholding tax
ineffective, or for any other reason) such Bank shall indemnify the Agent fully
for all amounts paid, directly or indirectly, by the Agent as tax or otherwise,
including penalties and interest, and including any taxes imposed by any
jurisdiction on the amounts payable to the Agent





                                       76
<PAGE>   84
under this Section, together with all costs and expenses (including Attorney
Costs).  The obligation of the Banks under this subsection shall survive the
payment of all Obligations and the resignation or replacement of the Agent.

         10.11   Collateral Matters.

                 (a)      The Agent is authorized on behalf of all the Banks,
without the necessity of any notice to or further consent from the Banks, from
time to time to take any action with respect to any Collateral or the
Collateral Documents which may be necessary to perfect and maintain perfected
the security interest in and Liens upon the Collateral granted pursuant to the
Collateral Documents.

                 (b)      The Banks irrevocably authorize the Agent, at its
option and in its discretion, to release any Lien granted to or held by the
Agent upon any Collateral (provided, that the Agent shall retain all cash
collateral received in respect of Letters of Credit until and unless such
Letters of Credit are subsequently surrendered) (i) upon termination of the
Commitments, the surrender of all Letters of Credit not Cash Collateralized and
payment in full of all Loans and all other Obligations known to the Agent and
payable under this Agreement or any other Loan Document; (ii) constituting
property sold or to be sold or disposed of as part of or in connection with any
disposition permitted hereunder; (iii) constituting property in which the
Company, any Guarantor or any of their Subsidiaries owned no interest at the
time the Lien was granted or at any time thereafter; (iv) constituting property
leased to the Company, any Guarantor or any of their Subsidiaries under a lease
which has expired or been terminated in a transaction permitted under this
Agreement or is about to expire and which has not been, and is not intended by
the Company, any Guarantor or any of their Subsidiaries to be, renewed or
extended; (v) consisting of an instrument evidencing Indebtedness or other debt
instrument, if the indebtedness evidenced thereby has been paid in full.  Upon
request by the Agent at any time, the Banks will confirm in writing the Agent's
authority to release particular types or items of Collateral pursuant to this
subsection 10.11(b), provided that the absence of any such confirmation for
whatever reason shall not affect the Agent's rights under this Section 10.11.

                 (c)      Each of the Banks acknowledges that, in connection
with creating, taking, perfecting or enforcing security interests in foreign
countries or jurisdictions, the Agent may need to be denominated as "security
trustee" or named or designated by some title or description other than
"agent."  Each of the Banks, therefore, agrees that, in the event the Agent
uses the designation "security trustee" or some other designation, the use of
such name, designation or phrase shall not in any way alter, amend or modify
the nature and scope of the Agent's duties and obligations as set forth in this
Agreement.  Without limiting the generality of the foregoing, the use of the
designation "security trustee" or any other phrase utilizing the word "trustee"
shall not create or impose on the Bank any fiduciary or heightened obligation
for the benefit of the Banks.  In all instances, regardless of (i) the
description or name used by the Agent or (ii) any statements about, or
descriptions of, the Agent contained in any





                                       77
<PAGE>   85
Collateral Documents, the express terms of this Agreement shall exclusively
define and govern the Agent's duties and obligations to the Banks.

                                 MISCELLANEOUS

         11.01   Amendments and Waivers.  No amendment or waiver of any
provision of this Agreement or any other Loan Document, and no consent with
respect to any departure by the Company therefrom, shall be effective unless
the same shall be in writing and signed by the Majority Banks (or by the Agent
at the written request of the Majority Banks) and the Company and acknowledged
by the Agent, and then any such waiver or consent shall be effective only in
the specific instance and for the specific purpose for which given; provided,
however, that no such waiver, amendment, or consent shall, unless in writing
and signed by all the Banks and the Company and acknowledged by the Agent, do
any of the following:

                 (a)      increase or extend the Commitment of any Bank (or

                                       78

that would reasonably be anticipated to increase the Aggregate Borrowing Base,
or waive any provision thereof that would reasonably be expected to have such
effect;

                 (h)      release any portion of the Collateral otherwise then
pursuant to Section 10.11 or the Collateral Documents (except where release
upon the consent of the Majority Banks is specifically provided for);

and, provided further, that (i) no amendment, waiver or consent shall, unless
in writing and signed by the Issuing Bank in addition to the Majority Banks or
all the Banks, as the case may be, affect the rights or duties of the Issuing
Bank under this Agreement or any L/C-Related Document relating to any Letter of
Credit Issued or to be Issued by it, (ii) no amendment, waiver or consent
shall, unless in writing and signed by the Agent in addition to the Majority
Banks or all the Banks, as the case may be, affect the rights or duties of the
Agent under this Agreement or any other Loan Document, and (iii) the Fee Letter
may be amended, or rights or privileges thereunder waived, in a writing
executed by the parties thereto.

         11.02   Notices.

                 (a)      All notices, requests, consents, approvals, waivers
and other communications shall be in writing (including, unless the context
expressly otherwise provides, by facsimile transmission, provided that any
matter transmitted by the Company by facsimile (i) shall be immediately
confirmed by a telephone call to the recipient at the number specified on
Schedule 11.02, and (ii) shall be followed promptly by delivery of a hard copy
original thereof) and mailed, faxed or delivered, to the address or facsimile
number specified for notices on Schedule 11.02; or, as directed to the Company
or the Agent, to such other address as shall be designated by such party in a
written notice to the other parties, and as directed to any other party, at
such other address as shall be designated by such party in a written notice to
the Company and the Agent.

                 (b)      All such notices, requests and communications shall,
when transmitted by overnight delivery, or faxed, be effective when delivered
for overnight (next-day) delivery, or transmitted in legible form by facsimile
machine, respectively, or if mailed, upon the third Business Day after the date
deposited into the U.S. mail, or if delivered, upon delivery; except that
notices pursuant to Article II, III or X to the Agent shall not be effective
until actually received by the Agent, and notices pursuant to Article III to
the Issuing Bank shall not be effective until actually received by the Issuing
Bank at the address specified for the "Issuing Bank" on the applicable
signature page hereof.

                 (c)      Any agreement of the Agent and the Banks herein to
receive certain notices by telephone or facsimile is solely for the convenience
and at the request of the Company.  The Agent and the Banks shall be entitled
to rely on the authority of any Person purporting to be a Person authorized by
the Company to give such notice and the Agent and the Banks shall not have any
liability to the Company or other Person on account of any action





                                       79
<PAGE>   87
taken or not taken by the Agent or the Banks in reliance upon such telephonic
or facsimile notice.  The obligation of the Company to repay the Loans and L/C
Obligations shall not be affected in any way or to any extent by any failure by
the Agent and the Banks to receive written confirmation of any telephonic or
facsimile notice or the receipt by the Agent and the Banks of a confirmation
which is at variance with the terms understood by the Agent and the Banks to be
contained in the telephonic or facsimile notice.

         11.03   No Waiver; Cumulative Remedies.  No failure to exercise and no
delay in exercising, on the part of the Agent or any Bank, any right, remedy,
power or privilege hereunder, shall operate as a waiver thereof; nor shall any
single or partial exercise of any right, remedy, power or privilege hereunder
preclude any other or further exercise thereof or the exercise of any other
right, remedy, power or privilege.

         11.04   Costs and Expenses.  The Company shall:

                 (a)      whether or not the transactions contemplated hereby
are consummated, pay or reimburse BofA (including in its capacity as Agent and
Issuing Bank) and each Bank within five Business Days after demand (subject to
subsection 5.01(e)) for all costs and expenses incurred by BofA (including in
its capacity as Agent and Issuing Bank) and each Bank in connection with the
development, preparation, delivery, administration, registration, filing,
recording and execution of, and any amendment, supplement, waiver or
modification to (in each case, whether or not consummated), this Agreement, any
Loan Document and any other documents prepared in connection herewith or
therewith, and the consummation of the transactions contemplated hereby and
thereby, including reasonable Attorney Costs incurred by BofA (including in its
capacity as Agent and Issuing Bank) and any Bank with respect thereto; and

                 (b)      pay or reimburse the Agent, the Arranger and each
Bank within five Business Days after demand (subject to subsection 5.01(e)) for
all costs and expenses (including Attorney Costs) incurred by them in
connection with the enforcement, attempted enforcement, or preservation of any
rights or remedies under this Agreement or any other Loan Document during the
existence of an Event of Default or after acceleration of the Loans (including
in connection with any "workout" or restructuring regarding the Loans, and
including in any Insolvency Proceeding or appellate proceeding).

         11.05   Company Indemnification.  Whether or not the transactions
contemplated hereby are consummated, the Company shall indemnify, defend and
hold the Agent-Related Persons, and each Bank and each of its respective
officers, directors, employees, counsel, agents and attorneys-in-fact (each, an
"Indemnified Person") harmless from and against any and all liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
charges, expenses and disbursements (including Attorney Costs) of any kind or
nature whatsoever which may at any time (including at any time following
repayment of the Loans, the termination of the Letters of Credit and the
termination, resignation or replacement of the





                                       80
<PAGE>   88
Agent or replacement of any Bank)  be imposed on, incurred by or asserted
against any such Person in any way relating to or arising out of this
Agreement, the Collateral Documents, the Guarantees or any document
contemplated by or referred to therein, or the transactions contemplated
thereby, or any action taken or omitted by any such Person under or in
connection with any of the foregoing, including with respect to any
investigation, litigation or proceeding (including any Insolvency Proceeding or
appellate proceeding) related to or arising out of this Agreement or the Loans
or Letters of Credit or the use of the proceeds thereof, whether or not any
Indemnified Person is a party thereto (all the foregoing, collectively, the
"Indemnified Liabilities"); provided, that the Company shall have no obligation
hereunder to any Indemnified Person with respect to Indemnified Liabilities
resulting solely from the gross negligence or willful misconduct of such
Indemnified Person. The agreements in this Section shall survive payment of all
other Obligations.  At the election of any Indemnified Person, the Company
shall defend such Indemnified Person using legal counsel satisfactory to such
Indemnified Person in such Person's sole discretion, at the sole cost and
expense of the Company.  All amounts owing under this Section 11.05 shall be
paid within 30 days after demand.

         11.06   Payments Set Aside.  Neither the Agent nor the Banks shall be
under any obligation to marshall any assets in favor of the Company or any
other Person or against or in payment of any or all of the Obligations.  To the
extent that the Company makes a payment to the Agent or the Banks, or the Agent
or the Banks exercise their right of set-off, and such payment or the proceeds
of such set-off or any part thereof are subsequently invalidated, declared to
be fraudulent or preferential, set aside or required (including pursuant to any
settlement entered into by the Agent or such Bank in its discretion) to be
repaid to a trustee, receiver or any other party, in connection with any
Insolvency Proceeding or otherwise, then (a) to the extent of such recovery the
obligation or part thereof originally intended to be satisfied shall be revived
and continued in full force and effect as if such payment had not been made or
such set-off had not occurred, and (b) each Bank severally agrees to pay to the
Agent upon demand its pro rata share of any amount so recovered from or repaid
by the Agent.

         11.07   Successors and Assigns.  The provisions of this Agreement
shall be binding upon and inure to the benefit of the parties hereto and their
respective successors and assigns, except that the Company may not assign or
transfer any of its rights or obligations under this Agreement without the
prior written consent of the Agent and each Bank.

         11.08   Assignments, Participations, Etc.

                 (a)      Any Bank may, with the written consent of the
Company, at all times other than during the existence of an Event of Default,
the Agent and the Issuing Bank, which consents shall not be unreasonably
withheld, at any time assign and delegate to one or more Eligible Assignees
(provided that no written consent of the Company, the Agent or the Issuing Bank
shall be required in connection with any assignment and delegation by a Bank to
an Eligible Assignee that is an Affiliate of such Bank) (each an "Assignee")
all, or any ratable





                                       81
<PAGE>   89
part of all, of the Loans, the Commitments, the L/C Obligations and the other
rights and obligations of such Bank hereunder, in a minimum amount of
$5,000,000 or any lesser amount that constitutes the entire remaining
Commitment; provided, however, that the Company and the Agent may continue to
deal solely and directly with such Bank in connection with the interest so
assigned to an Assignee until (i) written notice of such assignment, together
with payment instructions, addresses and related information with respect to
the Assignee, shall have been given to the Company and the Agent by such Bank
and the Assignee; (ii) such Bank and its Assignee shall have delivered to the
Company and the Agent an Assignment and Acceptance in the form of Exhibit D
("Assignment and Acceptance") together with any Note or Notes subject to such
assignment and (iii) the assignor Bank or Assignee has paid to the Agent a
processing fee in the amount of $3,500.

                 (b)      From and after the date that the Agent notifies the
assignor Bank that it has received (and provided its consent with respect to)
an executed Assignment and Acceptance and payment of the above-referenced
processing fee, (i) the Assignee thereunder shall be a party hereto and, to the
extent that rights and obligations hereunder have been assigned to it pursuant
to such Assignment and Acceptance, shall have the rights and obligations of a
Bank under the Loan Documents, and (ii) the assignor Bank shall, to the extent
that rights and obligations hereunder and under the other Loan Documents have
been assigned by it pursuant to such Assignment and Acceptance, relinquish its
rights and be released from its obligations under the Loan Documents.

                 (c)      Within five Business Days after its receipt of notice
by the Agent that it has received an executed Assignment and Acceptance and
payment of the processing fee, the Company shall execute and deliver to the
Agent, new Notes evidencing such Assignee's assigned Loans and Commitment and,
if the assignor Bank has retained a portion of its Loans and its Commitment,
replacement Notes in the principal amount of the Loans retained by the assignor
Bank (such Notes to be in exchange for, but not in payment of, the Notes held
by such Bank).  Immediately upon each Assignee's making its processing fee
payment under the Assignment and Acceptance, this Agreement shall be deemed to
be amended to the extent, but only to the extent, necessary to reflect the
addition of the Assignee and the resulting adjustment of the Commitments
arising therefrom. The Commitment allocated to each Assignee shall reduce such
Commitments of the assigning Bank pro tanto.

                 (d)      Any Bank may at any time sell to one or more
commercial banks or other Persons not Affiliates of the Company (a
"Participant") participating interests in any Loans, the Commitment of that
Bank and the other interests of that Bank (the "originating Bank") hereunder
and under the other Loan Documents; provided, however, that (i) the originating
Bank's obligations under this Agreement shall remain unchanged, (ii) the
originating Bank shall remain solely responsible for the performance of such
obligations, (iii) the Company, the Issuing Bank and the Agent shall continue
to deal solely and directly with the originating Bank in connection with the
originating Bank's rights and obligations under this Agreement and the other
Loan Documents, and (iv) no Bank shall transfer or grant





                                       82
<PAGE>   90
any participating interest under which the Participant has rights to approve
any amendment to, or any consent or waiver with respect to, this Agreement or
any other Loan Document, except to the extent such amendment, consent or waiver
would require unanimous consent of the Banks as described in the first proviso
to Section 11.01. In the case of any such participation, the Participant shall
not have any rights under this Agreement, or any of the other Loan Documents,
and all amounts payable by the Company hereunder shall be determined as if such
Bank had not sold such participation; except that, if amounts outstanding under
this Agreement are due and unpaid, or shall have been declared or shall have
become due and payable upon the occurrence of an Event of Default, each
Participant shall be deemed to have the right of set-off in respect of its
participating interest in amounts owing under this Agreement to the same extent
as if the amount of its participating interest were owing directly to it as a
Bank under this Agreement.

                 (e)      Notwithstanding any other provision in this
Agreement, any Bank may at any time create a security interest in, or pledge,
all or any portion of its rights under and interest in this Agreement and any
Note held by it in favor of any Federal Reserve Bank in accordance with
Regulation A of the FRB or U.S. Treasury Regulation 31 CFR Section 203.14, and
such Federal Reserve Bank may enforce such pledge or security interest in any
manner permitted under applicable law.

         11.09   Confidentiality.  Each Bank agrees to take and to cause its
Affiliates to take normal and reasonable precautions and exercise due care to
maintain the confidentiality of all information identified as "company private"
by the Company and provided to it by the Company or any Subsidiary, or by the
Agent on the Company's or such Subsidiary's behalf, under this Agreement or any
other Loan Document, and neither it nor any of its Affiliates shall use any
such information other than in connection with or in enforcement of this
Agreement and the other Loan Documents or in connection with other business now
or hereafter existing or contemplated with the Company or any Subsidiary;
except to the extent such information (i) was or becomes generally available to
the public other than as a result of disclosure by the Bank, or (ii) was or
becomes available on a  non-confidential basis from a source other than the
Company, provided that such source is not bound by a confidentiality agreement
with the Company known to the Bank; provided, however, that any Bank may
disclose such information (A) at the request or pursuant to any requirement of
any Governmental Authority to which the Bank is subject or in connection with
an examination of such Bank by any such authority; (B) pursuant to subpoena or
other court process; (C) when required to do so in accordance with the
provisions of any applicable Requirement of Law; (D) to the extent reasonably
required in connection with any litigation or proceeding to which the Agent,
any Bank or their respective Affiliates may be party; (E) to the extent
reasonably required in connection with the exercise of any remedy hereunder or
under any other Loan Document; (F) to such Bank's independent auditors and
other professional advisors; (G) to any Participant or Assignee, actual or
potential, provided that such Person agrees in writing to keep such information
confidential to the same extent required of the Banks hereunder; (H) as to any
Bank or its Affiliate, as expressly permitted under the terms of any other
document or





                                       83
<PAGE>   91
agreement regarding confidentiality to which the Company or any Subsidiary is
party or is deemed party with such Bank or such Affiliate; and (I) to its
Affiliates.

         11.10   Set-off.  In addition to any rights and remedies of the Banks
provided by law, if an Event of Default exists or the Loans have been
accelerated, each Bank is authorized at any time and from time to time, without
prior notice to the Company, any such notice being waived by the Company to the
fullest extent permitted by law, to set off and apply any and all deposits
(general or special, time or demand, provisional or final) at any time held by,
and other indebtedness at any time owing by, such Bank to or for the credit or
the account of the Company against any and all Obligations owing to such Bank,
now or hereafter existing, irrespective of whether or not the Agent or such
Bank shall have made demand under this Agreement or any Loan Document and
although such Obligations may be contingent or unmatured.  Each Bank agrees
promptly to notify the Company and the Agent after any such set-off and
application made by such Bank; provided, however, that the failure to give such
notice shall not affect the validity of such set-off and application.

         11.11   Automatic Debits of Fees.  With respect to any commitment fee,
arrangement fee, letter of credit fee or other fee, or any other cost or
expense (including Attorney Costs) due and payable to the Agent, the Issuing
Bank, BofA or the Arranger under the Loan Documents, the Company hereby
irrevocably authorizes BofA to debit any deposit account of the Company with
BofA in an amount such that the aggregate amount debited from all such deposit
accounts does not exceed such fee or other cost or expense.  If there are
insufficient funds in such deposit accounts to cover the amount of the fee or
other cost or expense then due, such debits will be reversed (in whole or in
part, in BofA's sole discretion) and such amount not debited shall be deemed to
be unpaid.  No such debit under this Section shall be deemed a set-off.

         11.12   Notification of Addresses, Lending Offices, Etc.  Each Bank
shall notify the Agent in writing of any changes in the address to which
notices to the Bank should be directed, of addresses of any Lending Office, of
payment instructions in respect of all payments to be made to it hereunder and
of such other administrative information as the Agent shall reasonably request.

         11.13   Counterparts.  This Agreement may be executed in any number of
separate counterparts, each of which, when so executed, shall be deemed an
original, and all of said counterparts taken together shall be deemed to
constitute but one and the same instrument.

         11.14   Severability.  The illegality or unenforceability of any
provision of this Agreement or any instrument or agreement required hereunder
shall not in any way affect or impair the legality or enforceability of the
remaining provisions of this Agreement or any instrument or agreement required
hereunder.





                                       84
<PAGE>   92
         11.15   No Third Parties Benefited.  This Agreement is made and
entered into for the sole protection and legal benefit of the Company, the
Banks, the Agent and the Agent-Related Persons, and their permitted successors
and assigns, and no other Person shall be a direct or indirect legal
beneficiary of, or have any direct or indirect cause of action or claim in
connection with, this Agreement or any of the other Loan Documents.

         11.16   Governing Law and Jurisdiction.

                 (a)      THIS AGREEMENT AND THE NOTES SHALL BE GOVERNED BY,
AND CONSTRUED IN ACCORDANCE WITH, THE LAW OF THE STATE OF CALIFORNIA; PROVIDED
THAT THE AGENT AND THE BANKS SHALL RETAIN ALL RIGHTS ARISING UNDER FEDERAL LAW.

                 (b)      ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS
AGREEMENT OR ANY OTHER LOAN DOCUMENT MAY BE BROUGHT IN THE COURTS OF THE STATE
OF CALIFORNIA OR OF THE UNITED STATES FOR THE NORTHERN DISTRICT OF CALIFORNIA,
AND BY EXECUTION AND DELIVERY OF THIS AGREEMENT, EACH OF THE COMPANY, THE AGENT
AND THE BANKS CONSENTS, FOR ITSELF AND IN RESPECT OF ITS PROPERTY, TO THE
NON-EXCLUSIVE JURISDICTION OF THOSE COURTS.  EACH OF THE COMPANY, THE AGENT AND
THE BANKS IRREVOCABLY WAIVES ANY OBJECTION, INCLUDING ANY OBJECTION TO THE
LAYING OF VENUE OR BASED ON THE GROUNDS OF FORUM NON CONVENIENS, WHICH IT MAY
NOW OR HEREAFTER HAVE TO THE BRINGING OF ANY ACTION OR PROCEEDING IN SUCH
JURISDICTION IN RESPECT OF THIS AGREEMENT OR ANY DOCUMENT RELATED HERETO.  THE
COMPANY, THE AGENT AND THE BANKS EACH WAIVE PERSONAL SERVICE OF ANY SUMMONS,
COMPLAINT OR OTHER PROCESS, WHICH MAY BE MADE BY ANY OTHER MEANS PERMITTED BY
CALIFORNIA LAW.

         11.17   Waiver of Jury Trial.  THE COMPANY, THE BANKS AND THE AGENT
EACH WAIVE THEIR RESPECTIVE RIGHTS TO A TRIAL BY JURY OF ANY CLAIM OR CAUSE OF
ACTION BASED UPON OR ARISING OUT OF OR RELATED TO THIS AGREEMENT, THE OTHER
LOAN DOCUMENTS, OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY, IN ANY
ACTION, PROCEEDING OR OTHER LITIGATION OF ANY TYPE BROUGHT BY ANY OF THE
PARTIES AGAINST ANY OTHER PARTY OR ANY AGENT- RELATED PERSON, PARTICIPANT OR
ASSIGNEE, WHETHER WITH RESPECT TO CONTRACT CLAIMS, TORT CLAIMS, OR OTHERWISE.
THE COMPANY, THE BANKS AND THE AGENT EACH AGREE THAT ANY SUCH CLAIM OR CAUSE OF
ACTION SHALL BE TRIED BY A COURT TRIAL WITHOUT A JURY.  WITHOUT LIMITING THE
FOREGOING, THE PARTIES FURTHER AGREE THAT THEIR RESPECTIVE RIGHT TO A TRIAL BY
JURY IS WAIVED BY OPERATION OF THIS SECTION AS TO ANY ACTION, COUNTERCLAIM OR
OTHER PROCEEDING WHICH SEEKS, IN WHOLE OR IN PART, TO CHALLENGE





                                       85

THE VALIDITY OR ENFORCEABILITY OF THIS AGREEMENT OR THE OTHER LOAN DOCUMENTS OR
ANY PROVISION HEREOF OR THEREOF.  THIS WAIVER SHALL APPLY TO ANY SUBSEQUENT
AMENDMENTS, RENEWALS, SUPPLEMENTS OR MODIFICATIONS TO THIS AGREEMENT AND THE
OTHER LOAN DOCUMENTS.

         11.18   Entire Agreement.  This Agreement, together with the other
Loan Documents, embodies the entire agreement and understanding among the
Company, the Banks and the Agent, and supersedes all prior or contemporaneous
agreements and understandings of such Persons, verbal or written, relating to
the subject matter hereof and thereof.

         11.19   ABN Facility.  The Company and ABN AMRO agree not to amend the
ABN AMRO Accounts Receivable Facility in any way that might adversely impact
the rights and remedies of the Agent or any Bank hereunder without obtaining
the prior written consent of the Agent and the Banks.  ABN AMRO agrees not to
take any action that would cause the Company to violate its obligations under
Section 8.10 or otherwise hereunder without obtaining the prior written consent
of the Agent and the Banks.

         11.20   Certain Closing Date Transitional Matters.

                 (a)      On the Closing Date, each Bank hereby sells and
assigns, without recourse, an amount of Loans and L/C Obligations equal to the
product of (i) the excess (if any) of its Original Percentage over its Closing
Date Percentage times (ii) the aggregate principal amount of Loans and L/C
Obligations outstanding on such date and each Bank hereby purchases an amount
of Loans and L/C Obligations equal to the product of (i) the excess (if any) of
its Closing Date Percentage over its Original Percentage times (ii) the
aggregate principal amount of Loans and L/C Obligations outstanding on such
date.  Each Bank selling Loans and L/C Obligations hereunder shall be deemed to
have sold (and each Bank purchasing Loans and L/C Obligations shall be deemed
to have purchased) a pro rata portion (based on the aggregate principal amount
of Loans and L/C Obligations then outstanding) of each of such selling Bank's
Loans and L/C Obligations.  Payments by each Bank purchasing Loans and L/C
Obligations hereunder shall be made to the Agent not later than 12:00 noon,
(San Francisco time) in immediately available funds, without setoff, deduction
or counterclaim, for the pro rata account (based upon the outstanding principal
amount of Loans and L/C Obligations being sold) of each selling Bank in an
amount equal to the aggregate principal amount of outstanding Loans and L/C
Obligations purchased by such Bank.

                 (b)      On and after the Closing Date, each Bank shall be
entitled to receive commitment fees under Section 2.10(b) of the Agreement and
interest and fees on Loans and L/C Obligations and on any other amount due

Closing Date in accordance with its Original Percentage and (ii) accrued on and
after the Closing Date in accordance with its Closing Date Percentage.

<PAGE>   94
                 (c)      On and after the Closing Date, to the extent that any
commitment and the other rights and obligations of any Bank existing at the
time immediately preceding the Closing Date have been assigned or delegated, as
applicable, to any Bank hereunder, such assignee Bank hereby assumes such
commitment and other obligations and shall have the rights and obligations of a
Bank hereunder and under the other Loan Documents and, to the extent that any
commitment and other obligations of any Bank existing at the time immediately

                                   LITIGATION

In November and December 1995, two class action lawsuits were filed against
California Microwave, Inc. and certain of its executive officers in the United
States District Court for the Northern District of California.  The plaintiffs
purport to represent a class of all persons who purchased California Microwave
common stock between September 6, 1994 and June 29, 1995.  The complaints
allege that defendants violated various federal securities laws through
material misrepresentations and omissions during such period of time.

                            to the Credit Agreement

                                FORM OF GUARANTY

               THIS GUARANTY (this "Guaranty"), dated as of December 31, 1996,
is made by [EF Data Corporation] [California Microwave Navigation Systems,
Inc.], [a California] [a Delaware] corporation (the "Guarantor"), in favor of
the Banks referred to in the Credit Agreement described below and Bank of
America National Trust and Savings Association, as agent for the Banks (in such
capacity, the "Agent").

WHEREAS:

       E.      The parent company of the Guarantor, California Microwave, Inc.,
a Delaware corporation (the "Borrower"), the Banks (as lenders and, as
appropriate, issuer of certain letters of credit for the account of the
Borrower) and the Agent are parties to that certain First Amended and Restated
Credit Agreement dated as even date herewith (as amended, modified, renewed or
extended from time to time, the "Credit Agreement").

       F.      It is a condition precedent to the borrowings and issuances of
letters of credit under the Credit Agreement that the Guarantor guarantee the
indebtedness and other obligations of the Borrower to the Agent and the Banks
under or in connection with the Credit Agreement as set forth herein.

       G.      The Guarantor, as the [wholly] [87%] owned subsidiary of the
Borrower, will derive substantial direct and indirect benefits from the making
of the loans to the Borrower and the issuances of letters of credit pursuant to
the Credit Agreement (which benefits are hereby acknowledged by the Guarantor).

       H.      Accordingly, to induce the Agent and the Banks to make such
loans and to issue the letters of credit, and in consideration thereof, the
Guarantor hereby agrees as follows:

               SECTION 1  Definitions; Interpretation.

               (a)      Terms Defined in Credit Agreement.  All capitalized
terms used in this Guaranty (including in the recitals hereof) and not
otherwise defined herein shall have the meanings assigned to them in the Credit
Agreement.

               (b)      UCC shall mean the Uniform Commercial Code as the same
may, from time to time, be in effect in the State of California; provided,
however, in the event that, by reason of mandatory provisions of law, any or
all of the attachment, perfection or priority of the security interest in any
Collateral is governed by the Uniform Commercial Code as in effect in a
jurisdiction other than the State of California, the term "UCC" shall mean the
Uniform Commercial Code as in effect in such other jurisdiction for purposes of
the provisions





                                      I-1
<PAGE>   157
hereof relating to such attachment, perfection or priority and for purposes of
definitions related to such provisions.

               (c)      Accounting Terms.  Unless the context otherwise
requires, all accounting terms not expressly defined herein shall be construed
and all financial computations required under this Guaranty made, in accordance
with GAAP, consistently applied.

               (d)      Interpretation.  The rules of interpretation set forth
in Section 1.02 of the Credit Agreement shall be applicable to this Guaranty
and are incorporated herein by this reference.

               SECTION 2  Guaranty.

               (a)      Guaranty.  The Guarantor hereby unconditionally and
irrevocably guarantees to the Agent and the Banks, and their respective
successors, endorsees, transferees and assigns, the full and prompt payment and
performance when due (whether at stated maturity, by required prepayment,
declaration, acceleration, demand or otherwise) of the Obligations; including,
without limitation, all unpaid principal of the Loans, all unpaid L/C
Obligations, all interest and fees accrued thereon, and all other amounts
payable by the Borrower to the Agent and the Banks thereunder or in connection
therewith.  "Obligations" is used herein in its most comprehensive sense and
includes any and all Obligations now existing or hereafter arising, whether
voluntary or involuntary and whether due or not due, absolute or contingent,
liquidated or unliquidated, determined or undetermined, and whether recovery
upon such indebtedness, liabilities and obligations may be or hereafter become
unenforceable or shall be an allowed or disallowed claim under the Bankruptcy
Code or other applicable law.  The foregoing indebtedness, liabilities and
other obligations of the Borrower, and all other indebtedness, liabilities and
obligations to be paid or performed by the Guarantor in connection with this
Guaranty (including any and all amounts due under Section 16), shall
hereinafter be collectively referred to as the "Guaranteed Obligations."

               (b)      Limitation of Guaranty.  To the extent that any court
of competent jurisdiction shall impose by final judgment under applicable law
(including the California Uniform Fraudulent Transfer Act and Section Section
544 and 548 of the Bankruptcy Code) any limitations on the amount of the
Guarantor's liability with respect to the Guaranteed Obligations which the
Agent or the Banks can enforce under this Guaranty, the Agent and the Banks by
their acceptance hereof accept such limitation on the amount of the Guarantor's
liability hereunder to the extent needed to make this Guaranty and the
Guarantor Documents fully enforceable and nonavoidable.

               SECTION 3  Liability of Guarantor.  The liability of the
Guarantor under this Guaranty shall be irrevocable, absolute, independent and
unconditional, and shall not be affected by any circumstance which might
constitute a discharge of a surety or guarantor other than the indefeasible
payment and performance in full of all Guaranteed Obligations.  In furtherance
of the foregoing and without limiting the generality thereof, the Guarantor
agrees as follows:

<PAGE>   158
               (i)  the Guarantor's liability hereunder shall be the immediate,
direct, and primary obligation of the Guarantor and shall not be contingent
upon the Agent's or any Bank's exercise or enforcement of any remedy it may
have against the Borrower or any other Person, or against any Collateral or
other security for any Guaranteed Obligations;

               (ii)  this Guaranty is a guaranty of payment when due and not
merely of collectibility;

               (iii)  the Agent and the Banks may enforce this Guaranty upon
the occurrence of a Default notwithstanding the existence of any dispute among
the Agent, the Banks and the Borrower with respect to the existence of such
Default;

               (iv)  the Guarantor's payment of a portion, but not all, of the
Guaranteed Obligations shall in no way limit, affect, modify or abridge the
Guarantor's liability for any portion of the Guaranteed Obligations remaining
unsatisfied; and

               (v)  the Guarantor's liability with respect to the Guaranteed
Obligations shall remain in full force and effect without regard to, and shall
not be impaired or affected by, nor shall the Guarantor be exonerated or
discharged by, any of the following events:

                        (A)    any insolvency, bankruptcy, reorganization,
arrangement, adjustment, composition, assignment for the benefit of creditors,
liquidation, winding up or dissolution of the Borrower, the Guarantor, any
other Subsidiary of the Borrower or other guarantor or any other Person;

                        (B)    any limitation, discharge, or cessation of the
liability of the Borrower, the Guarantor, any other Subsidiary of the Borrower
or other guarantor or any other Person for any Guaranteed Obligations due to
any statute, regulation or rule of law, or any invalidity or unenforceability
in whole or in part of any of the Guaranteed Obligations or the Loan Documents;

                        (C)  any merger, acquisition, consolidation or change
in structure of the Borrower, the Guarantor, any other Subsidiary of the
Borrower or other guarantor or Person, or any sale, lease, transfer or other
disposition of any or all of the assets or shares of the Borrower, the
Guarantor, any other guarantor or other Person;

                        (D)    any assignment or other transfer, in whole or in
part, of the Agent's or any Bank's interests in and rights under this Guaranty
or the other Loan Documents, including the Agent's or any Bank's right to
receive payment of the Guaranteed Obligations, or any assignment or other
transfer, in whole or in part, of the Agent's or any Bank's interests in and to
any of the Collateral or other collateral securing the Guaranteed Obligations;

                        (E)    any claim, defense, counterclaim or setoff,
other than that of prior performance, that the Borrower, the Guarantor, any
other guarantor or other Person may have or assert, including any defense of
incapacity or lack of corporate or other authority to execute any of the Loan
Documents;

<PAGE>   159
                        (F)    the Agent's or any Bank's amendment,
modification, renewal, extension, cancellation or surrender of any Loan
Document, any Guaranteed Obligations, any Collateral or other collateral
securing the Guaranteed Obligations, or the Agent's or any Bank's exchange,
release, or waiver of any Collateral or of any other collateral securing the
Guaranteed Obligations;

                        (G)    the Agent's or any Bank's exercise or
nonexercise of any power, right or remedy with respect to any of the
Collateral, or any other collateral securing any of the Guaranteed Obligations,
including the Agent's or any Bank's compromise, release, settlement or waiver
with or of the Borrower, the Guarantor, any other guarantor or any other
Person;

                        (H)    the Agent's or any Bank's vote, claim,
distribution, election, acceptance, action or inaction in any bankruptcy case
related to the Guaranteed Obligations;

                        (I)    any impairment or invalidity of any of the
Collateral or any other collateral securing any of the Guaranteed Obligations
or any failure to perfect any of the Liens of the Agent and the Banks thereon
or therein; and

                        (J)    any other guaranty, whether by the Guarantor or
any other Person, of all or any part of the Guaranteed Obligations or any other
indebtedness, obligations or liabilities of the Borrower to the Agent or the
Banks.

               SECTION 4  Consents of Guarantor.  The Guarantor hereby
unconditionally consents and agrees that, without notice to or further assent
from the Guarantor:

               (i)  the principal amount of the Guaranteed Obligations may be
increased or decreased and additional indebtedness or obligations of the
Borrower under the Loan Documents may be incurred, by one or more amendments,
modifications, renewals or extensions of any Loan Document or otherwise;

               (ii)  the time, manner, place or terms of any payment under any

any Loan Document or otherwise;

               (iii)  the time for the Borrower's (or any other Person's)
performance of or compliance with any term, covenant or agreement on its part
to be performed or observed under any Loan Document may be extended, or such
performance or compliance waived, or failure in or departure from such
performance or compliance consented to, all in such manner and upon such terms
as the Agent and the Banks may deem proper;

               (iv)  the Agent or the Banks may discharge or release, in whole
or in part, any other guarantor or any other Person liable for the payment and

                                      I-4
<PAGE>   160
Collateral or any other collateral, nor shall the Agent or the Banks be liable

sale) granted by any Loan Document or other security document or agreement, or
otherwise available to the Agent and the Banks, with respect to the Guaranteed
Obligations, any of the Collateral or other security for any or all of the
Guaranteed Obligations, even if the exercise of such right, remedy, power or
privilege affects or eliminates any right of subrogation or any other right of
the Guarantor against the Borrower;

all as the Agent and the Banks may deem advisable, and all without impairing,
abridging, releasing or affecting this Guaranty.

               SECTION 5  Guarantor's Waivers.

               (a)      Certain Waivers.  The Guarantor waives and agrees not
to assert:

               (i)  any right to require the Agent or any Bank to marshal
assets in favor of the Borrower, the Guarantor, any other guarantor or any
other Person, to proceed against the Borrower, any other guarantor or any other
Person, to proceed against or exhaust any of the Collateral or any other
security held for the Guaranteed Obligations, to give notice of the terms, time
and place of any public or private sale of personal property security
constituting the Collateral or other collateral for the Guaranteed Obligations

equivalent provision of any other applicable law) or to pursue any other right,
remedy, power or privilege of the Agent or any Bank whatsoever;

               (ii)  the defense of the statute of limitations in any action
hereunder or for the collection or performance of the Guaranteed Obligations;

<PAGE>   161
               (iv)  any defense based upon the Agent's or any Bank's errors or
omissions in the administration of the Guaranteed Obligations;

               (v)  any rights to set-offs and counterclaims;

               (vi)  any defense based upon an election of remedies (including,
if available, an election to proceed by nonjudicial foreclosure) which destroys
or impairs the subrogation rights of the Guarantor or the right of the
Guarantor to proceed against the Borrower or any other obligor of the
Guaranteed Obligations for reimbursement; and

               (vii)  without limiting the generality of the foregoing, to the
fullest extent permitted by law, any defenses or benefits that may be derived
from or afforded by applicable law limiting the liability of or exonerating
guarantors or sureties, or which may conflict with the terms of this Guaranty,
including any and all benefits that otherwise might be available to the
Guarantor under California Civil Code Section Section 1432, 2809, 2810, 2815,
2819, 2839, 2845, 2848, 2849, 2850, 2899 and 3433 and California Code of Civil
Procedure Section Section 580a, 580b, 580d and 726 (or equivalent provisions
under the laws of any other relevant jurisdiction).

               (b)      Additional Waivers.  The Guarantor waives any and all
notice of the acceptance of this Guaranty, and any and all notice of the
creation, renewal, modification, extension or accrual of the Guaranteed
Obligations, or the reliance by the Agent, and the Banks upon this Guaranty, or
the exercise of any right, power or privilege hereunder.  The Guaranteed
Obligations shall conclusively be deemed to have been created, contracted,
incurred and permitted to exist in reliance upon this Guaranty.  The Guarantor
waives promptness, diligence, presentment, protest, demand for payment, notice
of default, dishonor or nonpayment and all other notices to or upon the
Borrower, the Guarantor or any other Person with respect to the Guaranteed
Obligations.

               (c)      Independent Obligations.  The obligations of the
Guarantor hereunder are independent of and separate from the obligations of the
Borrower and any other guarantor and upon the occurrence and during the
continuance of any Event of Default, a separate action or actions may be
brought against the Guarantor, whether or not the Borrower or any such other
guarantor is joined therein or a separate action or actions are brought against
the Borrower or any such other guarantor.

               (d)      Financial Condition of Borrower.  The Guarantor shall
not have any right to require the Agent or the Banks to obtain or disclose any
information with respect to:  (i) the financial condition or character of the
Borrower or the ability of the Borrower to pay and perform the Guaranteed
Obligations; (ii) the Guaranteed Obligations; (iii) the Collateral or other
security for any or all of the Guaranteed Obligations; (iv) the existence or
nonexistence of any other guarantees of all or any part of the Guaranteed
Obligations; (v) any action or inaction on the part of the Agent or the Banks
or any other Person; or (vi) any other matter, fact or occurrence whatsoever.

<PAGE>   162
               SECTION 6  Subrogation.

               The Guarantor shall not have, and shall not directly or
indirectly exercise, (i) any rights that it may acquire by way of subrogation
under this Guaranty, by any payment hereunder or otherwise, (ii) any rights of
contribution, indemnification, reimbursement or similar suretyship claims
arising out of this Guaranty, or (iii) any other right which it might otherwise
have or acquire (in any way whatsoever) which could entitle it at any time to
share or participate in any right, remedy or security of the Banks or the Agent
as against the Borrower or other guarantors, whether in connection with this
Guaranty, any of the other Loan Documents or otherwise.  If any amount shall be
paid to the Guarantor on account of the foregoing rights at any time when all
the Guaranteed Obligations shall not have been paid in full, such amount shall
be held in trust for the benefit of the Agent and the Banks and shall forthwith
be paid to the Agent to be credited and applied to the Guaranteed Obligations,
whether matured or unmatured, in accordance with the terms of the Loan
Documents.

               SECTION 7  Subordination.

               (a)      Subordination to Payment of Guaranteed Obligations.
All payments on account of all indebtedness, liabilities and other obligations
of the Borrower to the Guarantor, whether created under, arising out of or in
connection with any documents or instruments evidencing any credit extensions
to Borrower or otherwise, including all principal on  any such credit
extensions, all interest accrued thereon, all fees and all other amounts
payable by the Borrower to the Guarantor under or in connection therewith,
whether now existing or hereafter arising, and whether due or to become due,
absolute or contingent, liquidated or unliquidated, determined or undetermined
(the "Subordinated Debt") shall be subject, subordinate and junior in right of
payment and exercise of remedies, to the extent and in the manner set forth
herein, to the prior payment in full in cash or cash equivalents of the
Guaranteed Obligations.

               (b)      No Payments.  As long as any of the Guaranteed
Obligations shall remain outstanding and unpaid, the Guarantor shall not accept
or receive any payment or distribution by or on behalf of the Borrower,
directly or indirectly, of assets of the Borrower of any kind or character,
whether in cash, property or securities, including on account of the purchase,
redemption or other acquisition of Subordinated Debt, as a result of any
collection, sale or other disposition of collateral, or by setoff, exchange or
in any other manner, for or on account of the Subordinated Debt ("Subordinated
Debt Payments"), except that prior to the occurrence of any Event of Default,
the Guarantor shall be entitled to accept and receive regularly scheduled
payments on the Subordinated Debt, in accordance with the terms of the
documents and instruments governing the Subordinated Debt.  In the event that,
notwithstanding the provisions of this Section 7, any Subordinated Debt
Payments shall be received in contravention of this Section 7 by the Guarantor
before all Guaranteed Obligations are paid in full in cash or cash equivalents,
such Subordinated Debt Payments shall be held in trust for the benefit of the
Agent and the Banks and shall be paid over or delivered to the Agent for
application to the payment in full in cash or cash equivalents of all
Guaranteed Obligations remaining unpaid to the extent necessary to give effect
to this Section 7, after giving effect to





                                      I-7
<PAGE>   163
any concurrent payments or distributions to the Agent, and the Banks in respect
of the Guaranteed Obligations.

               (c)      Subordination of Remedies. As long as any Guaranteed
Obligations shall remain outstanding and unpaid, the Guarantor shall not,
without the prior written consent of the Agent:

               (i)  accelerate, make demand or otherwise make due and payable
prior to the original stated maturity thereof any Subordinated Debt or bring
suit or institute any other actions or proceedings to enforce its rights or
interests under or in respect of the Subordinated Debt;

               (ii)  exercise any rights under or with respect to (A) any
guaranties of the Subordinated Debt, or (B) any collateral held by it,
including causing or compelling the pledge or delivery of any collateral, any
attachment of, levy upon, execution against, foreclosure upon or the taking of
other action against or institution of other proceedings with respect to any
collateral held by it, notifying any account debtors of the Borrower or
asserting any claim or interest in any insurance with respect to any
collateral, or attempt to do any of the foregoing;

               (iii)  exercise any rights to set-offs and counterclaims in
respect of any indebtedness, liabilities or obligations of the Guarantor to the
Borrower against any of the Subordinated Debt; or

               (iv) commence, or cause to be commenced, or join with any
creditor other than the Agent and the Banks in commencing, any bankruptcy,
insolvency or receivership proceeding against the Borrower.

               (d)      Subordination Upon Any Distribution of Assets of the
Borrower. In the event of any payment or distribution of assets of the Borrower
of any kind or character, whether in cash, property or securities, upon the
dissolution, winding up or total or partial liquidation or reorganization,
readjustment, arrangement or similar proceeding relating to the Borrower or its
property, whether voluntary or involuntary or in bankruptcy, insolvency,
receivership, arrangement or similar proceedings or upon an assignment for the
benefit of creditors, or upon any other marshalling or composition of the
assets and liabilities of the Borrower, or otherwise (i) all amounts owing on
account of the Guaranteed Obligations, including all interest accrued thereon
at the contract rate both before and after the initiation of any such
proceeding, whether or not an allowed claim in any such proceeding, shall first
be paid in full in cash, or payment provided for in cash or in cash
equivalents, before any Subordinated Debt Payment is made; and (ii) to the
extent permitted by applicable law, any Subordinated Debt Payment to which the
Guarantor would be entitled except for the provisions hereof, shall be paid or
delivered by the trustee in bankruptcy, receiver, assignee for the benefit of
creditors or other liquidating agent making such payment or distribution 
directly to the Agent (on behalf of the Banks) for application to
the payment of the Guaranteed Obligations in accordance with clause (i), after
giving effect to any concurrent payment or 





                                      I-8
<PAGE>   164
distribution or provision therefor to the Agent or the Banks in respect of such
Guaranteed Obligations.

               (e)      Authorization to Agent.  If, while any Subordinated
Debt is outstanding, any bankruptcy, insolvency, reorganization, receivership,
arrangement, marshalling of assets and liabilities or similar proceeding is
commenced by or against the Borrower or its property:

               (i)  the Agent, when so instructed by the Majority Banks, is
hereby irrevocably authorized and empowered (in the name of the Banks or in the
name of the Guarantor or otherwise), but shall have no obligation, to demand,
sue for, collect and receive every payment or distribution in respect of the
Subordinated Debt and give acquittance therefor and to file claims and proofs
of claim and take such other action (including voting the Subordinated Debt) as
it may deem necessary or advisable for the exercise or enforcement of any of
the rights or interests of the Agent and the Banks; and

               (ii)  the Guarantor shall promptly take such action as the Agent
(on instruction from the Majority Banks) may reasonably request (A) to collect
the Subordinated Debt for the account of the Banks and to file appropriate
claims or proofs of claim in respect of the Subordinated Debt, (B) to execute
and deliver to the Agent, such powers of attorney, assignments and other
instruments as it may request to enable it to enforce any and all claims with
respect to the Subordinated Debt, and (C) to collect and receive any and all
Subordinated Debt Payments.

               SECTION 8  Continuing Guaranty; Reinstatement.

               (a)      Continuing Guaranty.  This Guaranty is a continuing
guaranty and agreement of subordination and shall continue in effect and be
binding upon the Guarantor until termination of the Commitments and payment and
performance in full of the Guaranteed Obligations.

               (b)      Reinstatement.  This Guaranty shall continue to be
effective or shall be reinstated and revived, as the case may be, if, for any
reason, any payment of the Guaranteed Obligations by or on behalf of the
Borrower (or receipt of any proceeds of Collateral) shall be rescinded,
invalidated, declared to be fraudulent or preferential, set aside, voided or
otherwise required to be repaid to the Borrower, its estate, trustee, receiver
or any other Person (including under the Bankruptcy Code or other state or
federal law), or must otherwise be restored by the Agent or any Bank, whether
as a result of proceedings in bankruptcy or reorganization or otherwise.  To
the extent any payment is so rescinded, set aside, voided or otherwise repaid
or restored, the Guaranteed Obligations shall be revived in full force and
effect without reduction or discharge for such payment.  All losses, damages,
costs and expenses that the Agent or the Banks may suffer or incur as a result
of any voided or otherwise set aside payments shall be specifically covered by
the indemnity in favor of the Banks and the Agent contained in Section 16.

<PAGE>   165
               SECTION 9  Payments.  The Guarantor hereby agrees, in
furtherance of the foregoing provisions of this Guaranty and not in limitation
of any other right which the Agent or any Bank or any other Person may have
against the Guarantor by virtue hereof, upon the failure of the Borrower to pay
or perform any of the Guaranteed Obligations when and as the same shall become
due, whether at stated maturity, by required prepayment, declaration,
acceleration, demand or otherwise (including amounts that would become due but
for the operation of the automatic stay under Section 362(a) of the Bankruptcy
Code), the Guarantor shall forthwith pay, or cause to be paid, in cash, to the
Agent an amount equal to the amount of the Guaranteed Obligations then due as
aforesaid (including interest which, but for the filing of a petition in
bankruptcy with respect to the Borrower, would have accrued on such Guaranteed
Obligations, whether or not a claim is allowed against the Borrower for such
interest in any such bankruptcy proceeding).  The Guarantor shall make each
payment hereunder, unconditionally in full without set-off, counterclaim or
other defense, or deduction for any Taxes, on the day when due in Dollars and
in same day or immediately available funds, to the Agent at the Agent's Payment
Office.  All such payments shall be promptly applied from time to time by the
Agent (i) first, to the payment of any fees, costs, expenses and other amounts
due from the Guarantor to the Agent hereunder and under the other Loan
Documents to which the Guarantor is party, and (ii) second, to the payment of
the other Guaranteed Obligations in such order of application as the Agent and
the Majority Banks in their sole discretion may choose.

               SECTION 10  Representations and Warranties.  The Guarantor
represents and warrants to the Agent and each Bank that:

               (a)      Organization and Powers.  The Guarantor is a
corporation duly organized, validly existing and in good standing under the law
of the jurisdiction of its incorporation, is qualified and licensed to do
business and is in good standing in each jurisdiction where its ownership,
lease or operation of property or the conduct of its business requires such
qualification or license or approval and has all requisite power and authority
and all governmental licenses, authorizations, consents and approvals to own
its assets and carry on its business and to execute, deliver and perform its
obligations under this Guaranty and the other Loan Document to which it is
party.

               (b)      Authorization; No Conflict.  The execution, delivery
and performance by the Guarantor of this Guaranty and the other Loan Document
to which it is party have been duly authorized by all necessary corporate
action of the Guarantor, and do not and will not: (i) contravene the terms of
the certificate or articles, as the case may be, of incorporation and the
bylaws of the Guarantor or result in a breach of or constitute a default, or
result in the creation of a Lien under any document evidencing any Contractual
Obligation to which the Guarantor is a party or by which it or its properties
may be bound or affected; or (ii) violate any provision of any law, rule,
regulation, order, writ, judgment, injunction, decree or the like binding on or
affecting the Guarantor.

               (c)      Binding Obligation.  This Guaranty and the other Loan
Documents to which it is party constitute, or when delivered under the Credit
Agreement will constitute, the legal, valid and binding obligations of the
Guarantor, enforceable against the Guarantor in





                                      I-10
<PAGE>   166
accordance with their respective terms except as enforceability may be limited
by applicable bankruptcy, insolvency, or similar laws affecting the enforcement
of creditors' rights generally or by equitable principles relating to
enforceability.

               (d)      Governmental Consents.  No authorization, consent,
approval, license, exemption of, or filing or registration with, any
Governmental Authority, or approval or consent of any other Person, is required
for the due execution, delivery or performance by the Guarantor of this
Guaranty and the other Loan Document to which it is party.

               (e)      No Prior Assignment.  The Guarantor has not previously
assigned any interest in the Subordinated Debt referred to in Section 7 or any
collateral relating thereto, no Person other than the Guarantor owns an
interest in the Subordinated Debt or any such collateral (whether as joint
holders of the Subordinated Debt, participants or otherwise), and the entire
Subordinated Debt is owing only to the Guarantor.

               (f)      Solvency.  Immediately prior to and after and giving
effect to the incurrence of the Guarantor's obligations under this Guaranty the
Guarantor will be Solvent.

               (g)      Consideration.  The Guarantor has received at least
"reasonably equivalent value" (as such phrase is used in Section 548 of the
Bankruptcy Code, in Section 3439.04 of the California Uniform Fraudulent
Transfer Act and in comparable provisions of other applicable law) and more
than sufficient consideration to support its obligations hereunder in respect
of the Guaranteed Obligations and under any of the Collateral Documents to
which it is a party.

               (h)      Independent Investigation.  The Guarantor hereby
acknowledges that it has undertaken its own independent investigation of the
financial condition of the Borrower and all other matters pertaining to this
Guaranty and further acknowledges that it is not relying in any manner upon any
representation or statement of the Agent or any Bank with respect thereto.  The
Guarantor represents and warrants that it has received and reviewed copies of
the Loan Documents and that it is in a position to obtain, and it hereby
assumes full responsibility for obtaining, any additional information
concerning the financial condition of the Borrower and any other matters
pertinent hereto that the Guarantor may desire.  The Guarantor is not relying
upon or expecting the Agent or any Bank to furnish to the Guarantor any
information now or hereafter in the Agent's or any such Bank's possession
concerning the financial condition of the Borrower or any other matter.

               (i)  Litigation.  There are no actions, suits proceedings,
claims or disputes or other contingent liabilities pending, or to the best of
the knowledge of the Guarantor, threatened or contemplated at law, in equity,
in arbitration or before any Governmental Authority, against the Guarantor or
its properties which if determined adversely would reasonably be expected to
have a material adverse effect on the operations, business, properties or
condition (financial or otherwise) or prospects of the Guarantor.





                                      I-11
<PAGE>   167
               SECTION 11  Reporting Covenants.  So long as any Guaranteed
Obligations shall remain unsatisfied or any Bank shall have any Commitment, the
Guarantor agrees that it will furnish to the Agent in sufficient copies for
distribution to the Banks:

               (a)      Additional Information.  The Guarantor will furnish to
the Agent:  (i) prompt written notice of any condition or event which has
resulted, or that could reasonably be expected to result, in a Material Adverse
Effect; and (ii) such other information respecting the operations, properties,
business or condition (financial or otherwise) of the Guarantor or its
Subsidiaries as any Bank (through the Agent) may from time to time reasonably
request.

               SECTION 12  Additional Affirmative Covenants.  So long as any
Guaranteed Obligations shall remain unsatisfied or any Bank shall have any
Commitment, the Guarantor agrees that:

               (a)      Preservation of Existence, Etc.  The Guarantor will,
and will cause each of its Subsidiaries to, maintain and preserve its corporate
existence, its rights to transact business and all other rights, franchises and
privileges necessary or desirable in the normal course of its business and
operations and the ownership of its properties.

               (b)      Foreign Collateral.  Upon or before the date eight
months after the Closing Date the Guarantor shall provide:  (i) Foreign
Security Agreements duly executed and delivered by the Guarantor, granting a
first priority perfected security and interest in the Foreign Collateral; and
(ii) legal opinions relating to the Foreign Security Agreements of legal
counsel, acceptable to the Agent and the Banks, in such of the jurisdictions
where Foreign Collateral is located as the Agent and the Banks may designate
and in a form and substance satisfactory to the Agent and the Banks.

               (c)      Further Assurances and Additional Acts.  The Guarantor
will execute, acknowledge, deliver, file, notarize and register at its own
expense all such further agreements, instruments, certificates, documents and
assurances and perform such acts as the Agent or the Majority Banks shall deem
necessary or appropriate to effectuate the purposes of this Guaranty and the
other Loan Documents to which the Guarantor is a party, and promptly provide
the Agent with evidence of the foregoing satisfactory in form and substance to
the Agent and the Majority Banks.

               (d)      Credit Agreement Covenants.  The Guarantor will
observe, perform and comply with all covenants applicable to the Guarantor set
forth in Articles VII and VIII of the Credit Agreement, which by their terms
the Borrower is required to cause the Guarantor to observe, perform and comply
with, as if such covenants were set forth in full herein.

               SECTION 13  Negative Covenants.  So long as any Guaranteed
Obligations shall remain unsatisfied or any Bank shall have any Commitment, the
Guarantor agrees that:

               (a)      Restrictions on Fundamental Changes.  The Guarantor
will not, and will not permit any of its Subsidiaries to, (i) liquidate, wind
up or dissolve itself (or suffer any liquidation or dissolution), or (ii) merge
with or consolidate into, or acquire all or substantially





                                      I-12
<PAGE>   168
all of the assets of, any Person, or sell, transfer, lease or otherwise dispose
of (whether in one transaction or in a series of transactions) all or
substantially all of its assets, except that the Guarantor may merge with or
consolidate into any other Person, provided that (1) the Guarantor is the
surviving corporation and (2) no such merger or consolidation shall be made
while there exists a Default or if a Default would occur as a result thereof.

               (b)  Distributions.  The Guarantor will not grant or otherwise
agree to or suffer to exist any consensual restrictions on its ability to pay
dividends and make other distributions to the Borrower, or to pay any
Indebtedness owed to the Borrower or transfer properties and assets to the
Borrower, except arising under the Loan Documents.

               SECTION 14  Notices.  All notices and other communications
provided for hereunder shall, unless otherwise stated herein, be in writing
(including by facsimile) and shall be mailed, sent or delivered (i) if to the
Agent or any Bank, at or to its address or facsimile number set forth in the
Credit Agreement, and (ii) if to the Guarantor, at or to its address or
facsimile number set forth below its name on the signature page hereof, or at
or to such other address or facsimile number as such party shall have
designated in a written notice to the other party.  All such notices and
communications shall be delivered and shall be effective in the manner
specified in Section 11.02 of the Credit Agreement.

               SECTION 15  No Waiver; Cumulative Remedies.  No failure on the
part of the Agent or any Bank to exercise, and no delay in exercising, any
right, remedy, power or privilege hereunder or under any other Loan Document
shall operate as a waiver thereof, nor shall any single or partial exercise of
any such right, remedy, power or privilege preclude any other or further
exercise thereof or the exercise of any other right, remedy, power or
privilege.  The rights and remedies under this Guaranty and the other Loan
Documents are cumulative and not exclusive of any rights, remedies, powers and
privileges that may otherwise be available to the Agent or any Bank.

               SECTION 16  Costs and Expenses; Indemnification.

               (a)      Costs and Expenses.  The Guarantor agrees to pay on
demand:

               (i)  the reasonable out-of-pocket costs and expenses of the
Agent and any of its Affiliates, and the reasonable fees and disbursements of
counsel to the Agent (including allocated costs of internal counsel), in
connection with the negotiation, preparation, execution, delivery and
administration of this Guaranty or any other Loan Document to which the
Guarantor is party, and any amendments, modifications or waivers of the terms
thereof; and

               (ii)  all costs and expenses of the Agent, its Affiliates and
each of the Banks, and fees and disbursements of counsel (including allocated
costs of internal counsel), in connection with the enforcement or attempted
enforcement, or preservation of any rights or interests under, this Guaranty
and any other Loan Document to which the Guarantor is a party, and any
out-of-court workout or other refinancing or restructuring or any bankruptcy
case, including any losses, costs and expenses sustained by the Agent and any
of the Banks as a result of any





                                      I-13
<PAGE>   169
failure by the Guarantor to perform or observe its obligations contained in
this Guaranty or any other Loan Document to which the Guarantor is a party.

               (b)      Indemnification.  In addition, whether or not the
transactions contemplated by the Loan Documents shall be consummated, the
Guarantor hereby agrees to indemnify the Agent and each Bank, any Affiliate
thereof, and their respective directors, officers, employees, agents, counsel
and other advisors (each an "Indemnified Person"), against and hold each of
them harmless from any and all liabilities, obligations, losses, claims,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
of any kind or nature whatsoever, including the reasonable fees and
disbursements of counsel to an Indemnified Person (including allocated costs of
internal counsel), which may be imposed on, incurred by, or asserted against
any Indemnified Person, (i) in any way relating to or arising out of this
Guaranty or any other Loan Document, the Guaranteed Obligations, or the
transactions contemplated hereby or thereby, or (ii) with respect to any
investigation, litigation or other proceeding relating to any of the foregoing,
irrespective of whether the Indemnified Person shall be designated a party
thereto (the "Indemnified Liabilities"); provided that the Guarantor shall not
be liable to any Indemnified Person for any portion of such Indemnified
Liabilities resulting solely from such Indemnified Person's gross negligence or
willful misconduct.  If and to the extent that the foregoing indemnification is
for any reason held unenforceable, the Guarantor agrees to make the maximum
contribution to the payment and satisfaction of each of the Indemnified
Liabilities which is permissible under applicable law.

               (c)      Defense.  At the election of any Indemnified Person,
the Guarantor shall defend such Indemnified Person using legal counsel
satisfactory to such Indemnified Person in such Person's sole discretion, at
the sole cost and expense of the Guarantor.

               (d)      Interest.  Any amounts payable to the Agent or any Bank
under this Section 16 if not paid upon demand shall bear interest from the date
of such demand until paid in full, at the rate of interest set forth in Section
2.09(c) of the Credit Agreement.

               SECTION 17  Right of Set-Off.  If an Event of Default exists
each Bank is hereby authorized at any time and from time to time, without
notice to the Guarantor (any such notice being expressly waived by the
Guarantor), to set off and apply any and all deposits (general or special, time
or demand, provisional or final) at any time held and other indebtedness at any
time owing by such Bank to or for the credit or the account of the Guarantor
against any and all of the obligations of the Guarantor now or hereafter
existing under this Guaranty, irrespective of whether or not such Bank shall
have made any demand upon the Borrower or the Guarantor under the Loan
Documents and although such obligations may be contingent and unmatured.  Each
Bank shall promptly notify the Guarantor (through the Agent) after any such
set-off and application made by it; provided, however, that the failure to give
such notice shall not affect the validity of such setoff and application.  The
rights of the Banks under this Section 17 are in addition to other rights and
remedies (including other rights of set-off) which the Banks may have.





                                      I-14
<PAGE>   170
               SECTION 18  Survival.  All covenants, agreements,
representations and warranties made in this Guaranty shall survive the
execution and delivery of this Guaranty, and shall continue in full force and
effect so long as any Bank has any Commitment or any Guaranteed Obligations
remain unsatisfied.  Without limiting the generality of the foregoing, the
obligations of the Guarantor under Section 16 shall survive the satisfaction of
the Guaranteed Obligations and the termination of the Commitments.

               SECTION 19  Benefits of Guaranty.  This Guaranty is entered into
for the sole protection and benefit of the Agent and each Bank and its
successors and assigns, and no other Person shall be a direct or indirect
beneficiary of, or shall have any direct or indirect cause of action or claim
in connection with, this Guaranty.  The Agent and the Banks, by their
acceptance of this Guaranty, shall not have any obligations under this Guaranty
to any Person other than the Guarantor, and such obligations shall be limited
to those expressly stated herein.

               SECTION 20  Binding Effect; Assignment.

               (a)      Binding Effect.  This Guaranty shall be binding upon
the Guarantor and its successors and assigns, and inure to the benefit of and
be enforceable by the Agent and each Bank and their respective successors,
endorsees, transferees and assigns.

               (b)      Assignment.  The Guarantor shall not have the right to
assign or transfer its rights and obligations hereunder or under any other Loan
Documents to which it is a party without the prior written consent of the
Banks.  Each Bank may, without notice to or consent by the Guarantor, sell,
assign, transfer or grant participations in all or any portion of such Bank's
rights and obligations hereunder in connection with any sale, assignment,
transfer or grant of a participation by such Bank under Section 11.08 of the
Credit Agreement of or in its rights and obligations thereunder and under the
other Loan Documents.  The Guarantor agrees that in connection with any such
sale, assignment, transfer or grant by any Bank, such Bank may deliver to the
prospective participant or assignee financial statements and other relevant
information relating to the Guarantor and its Subsidiaries.  In the event of
any grant of a participation, the participant (i) shall be deemed to have a
right of setoff under Section 17 in respect of its participation to the same
extent as if it were such "Bank"; and (ii) shall also be entitled to the
benefits of Section 16.

               SECTION 21  Governing Law.  THIS GUARANTY SHALL BE GOVERNED BY,
AND CONSTRUED IN ACCORDANCE WITH, THE LAW OF THE STATE OF CALIFORNIA.

               SECTION 22  Submission to Jurisdiction.  ANY LEGAL ACTION OR
PROCEEDING WITH RESPECT TO THIS GUARANTY OR ANY OTHER LOAN DOCUMENT MAY BE
BROUGHT IN THE COURTS OF THE STATE OF CALIFORNIA OR OF THE UNITED STATES FOR
THE NORTHERN DISTRICT OF CALIFORNIA, AND BY EXECUTION AND DELIVERY OF THIS
AGREEMENT, EACH OF THE GUARANTOR, THE AGENT AND THE BANKS CONSENTS, FOR ITSELF
AND IN RESPECT OF ITS PROPERTY, TO THE NON-EXCLUSIVE JURISDICTION OF THOSE
COURTS.  EACH OF THE GUARANTORS, THE AGENT





                                      I-15
<PAGE>   171
AND THE BANKS IRREVOCABLY WAIVES ANY OBJECTION, INCLUDING ANY OBJECTION TO THE
LAYING OF VENUE OR BASED ON THE GROUNDS OF FORUM NON CONVENIENS, WHICH IT MAY
NOW OR HEREAFTER HAVE TO THE BRINGING OF ANY ACTION OR PROCEEDING IN SUCH
JURISDICTION IN RESPECT OF THIS AGREEMENT OR ANY DOCUMENT RELATED HERETO.  THE
GUARANTOR, THE AGENT AND THE BANKS EACH WAIVE PERSONAL SERVICE OF ANY SUMMONS,
COMPLAINT OR OTHER PROCESS, WHICH MAY BE MADE BY ANY OTHER MEANS PERMITTED BY
CALIFORNIA LAW.

               (a)      Appointment of Process Agent.  The Guarantor hereby
irrevocably appoints the Borrower (in such capacity the "Process Agent"), as
its authorized agent with all powers necessary to receive on its behalf service
of copies of the summons and complaint and any other process which may be
served in any action or proceeding arising out of or relating to this Guaranty
and the other Loan Documents in any of the courts in and of the State of
California.  Such service may be made by mailing or delivering a copy of such
process to the Guarantor in care of the Process Agent at the Process Agent's
address set forth in the Credit Agreement address and the Guarantor hereby
irrevocably authorizes and directs the Process Agent to accept such service on
its behalf and agrees that the failure of the Process Agent to give any notice
of any such service to the Guarantor shall not impair or affect the validity of
such service or of any judgment rendered in any action or proceeding based
thereon.  As an alternative method of service, the Guarantor also irrevocably
consents to the service of any and all process in any such action or proceeding
by the mailing of copies of such process to the Guarantor at its address
specified below its signature.  If for any reason the Borrower shall cease to
act as Process Agent, the Guarantor shall appoint forthwith, in the manner
provided for herein, a successor Process Agent qualified to act as an agent for
service of process with respect to all courts in and of the State of California
and acceptable to the Agent.

               (b)      No Limitation.  Nothing in this Section 22 shall affect
the right of the Agent and the Banks to serve legal process in any other manner
permitted by law or limit the right of the Agent and the Banks to bring any
action or proceeding against the Guarantor or its property in the courts of
other jurisdictions.

               SECTION 23  Waiver of Jury Trial.  THE GUARANTOR HEREBY AGREES
TO WAIVE, AND THE AGENT AND THE BANKS BY THEIR ACCEPTANCE HEREOF HEREBY AGREE
TO WAIVE, THEIR RESPECTIVE RIGHTS TO A TRAIL BY JURY OF ANY CLAIM OR CAUSE OF
ACTION BASED UPON OR ARISING OUT OF OR RELATED TO THIS GUARANTY, THE OTHER
GUARANTOR DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY IN ANY
ACTION, PROCEEDING OR OTHER LITIGATION OF ANY TYPE BROUGHT BY ANY OF THE
PARTIES AGAINST ANY OTHER PARTY OR PARTIES, WHETHER WITH RESPECT TO CONTRACT
CLAIMS, TORT CLAIMS, OR OTHERWISE.  THE GUARANTOR HEREBY AGREES, AND THE AGENT
AND THE BANKS BY THEIR





                                      I-16
<PAGE>   172
ACCEPTANCE HEREOF HEREBY AGREE, THAT ANY SUCH CLAIM OR CAUSE OF ACTION SHALL BE
TRIED BY A COURT TRIAL WITHOUT A JURY.  WITHOUT IN ANY WAY LIMITING THE
FOREGOING, THE GUARANTOR FURTHER AGREES, AND THE AGENT AND THE BANKS BY THEIR
ACCEPTANCE HEREOF FURTHER AGREE, THAT THEIR RESPECTIVE RIGHT TO A TRIAL BY JURY
IS WAIVED BY OPERATION OF THIS SECTION AS TO ANY ACTION, COUNTERCLAIM, OR OTHER
PROCEEDING WHICH SEEKS, IN WHOLE OR IN PART, TO CHALLENGE THE VALIDITY OR
ENFORCEABILITY OF THIS GUARANTY OR THE OTHER GUARANTOR DOCUMENTS OR ANY
PROVISION HEREOF OR THEREOF.  THIS WAIVER SHALL APPLY TO ANY SUBSEQUENT
AMENDMENTS, RENEWALS, SUPPLEMENTS OR MODIFICATIONS TO THIS GUARANTY AND THE
OTHER GUARANTOR DOCUMENTS.  A COPY OF THIS SECTION 23 MAY BE FILED WITH ANY
COURT AS WRITTEN EVIDENCE OF THE WAIVER OF THE RIGHT TO TRIAL BY JURY AND
CONSENT TO TRIAL BY COURT.

               SECTION 24  Entire Agreement; Amendments and Waivers.

               (a)      Entire Agreement.  This Guaranty and the other Loan
Documents constitute the entire agreement of the Guarantor with respect to the
matters set forth herein and supersede any prior agreements, commitments,
drafts, communications, discussions and understandings, oral or written, with
respect thereto conditions to the full effectiveness of this Guaranty.

               (b)      Amendments and Waivers.  Except to the extent otherwise
provided in the Credit Agreement, this Guaranty and the other Loan Documents
may not be amended except by a writing signed by the Guarantor and the Agent,
with the written consent of the Majority Banks.  No waiver of any rights of the
Agent and the Banks under any provision of this Guaranty or consent to any
departure by the Guarantor therefrom shall be effective unless in writing and
signed by the Agent, with the written consent of the Majority Banks.  Any such
amendment, waiver or consent shall be effective only in the specific instance
and for the specific purpose for which given.

               SECTION 25  Limitation on Liability.  No claim shall be made by
the Guarantor or its Affiliates against the Agent, the Banks or any of their
respective Affiliates, directors, employees, attorneys or agents for any
special, indirect, exemplary, consequential or punitive damages in respect of
any breach or wrongful conduct (whether or not the claim therefor is based on
contract, tort or duty imposed by law), in connection with, arising out of or
in any way related to the transactions contemplated by this Guaranty or the
other Guarantor Documents or any act or omission or event occurring in
connection therewith; and the Guarantor hereby waives, releases and agrees not
to sue upon any such claim for any such damages, whether or not accrued and
whether or not known or suspected to exist in its favor.

               SECTION 26  Interpretation.  This Guaranty and the other Loan
Documents to which the Guarantor is a party are the result of negotiations
between and have been reviewed by counsel to the Agent, the Guarantor and other
parties, and are the product of all parties hereto.  Accordingly, this Guaranty
and the other Guarantor Documents shall not be construed against any of the
Banks or the Agent merely because of the Agent's or any Bank's involvement in
the preparation thereof.

               SECTION 27  Knowing and Explicit Waivers.  THE GUARANTOR
ACKNOWLEDGES THAT IT HAS EITHER OBTAINED THE ADVICE OF LEGAL COUNSEL OR HAS HAD
THE OPPORTUNITY TO OBTAIN SUCH ADVICE IN CONNECTION WITH THE TERMS AND
PROVISIONS OF THIS GUARANTY.  THE GUARANTOR ACKNOWLEDGES AND AGREES THAT EACH
OF THE WAIVERS AND CONSENTS SET FORTH HEREIN, INCLUDING THOSE CONTAINED IN
SECTIONS 3 THROUGH 5, ARE MADE WITH FULL KNOWLEDGE OF THEIR SIGNIFICANCE AND
CONSEQUENCES.  ADDITIONALLY, THE GUARANTOR ACKNOWLEDGES AND AGREES THAT BY
EXECUTING THIS GUARANTY, IT IS WAIVING CERTAIN RIGHTS, BENEFITS, PROTECTIONS
AND DEFENSES TO WHICH IT MAY OTHERWISE BE ENTITLED UNDER APPLICABLE LAW,

<PAGE>   183
the amount involved does not exceed $500,000 or where the Account or Right to
Payment does not exceed $1,000,000 or would not be materially impaired;

                 (iii) if any discount, allowance, credit, extension of time

on, or compromise or settle, an Account or other Right to Payment exists or
occurs, or if, to the knowledge of the Borrower, any dispute, setoff, claim,
counterclaim or defense exists or has been asserted or threatened with respect
to an Account or other Right to Payment (collectively such events the
"Disclosure Events"), disclose such fact fully to the Agent in the Books
relating to such Account or other Right to Payment and in connection with any
invoice or report furnished by the Borrower to the Agent relating to such
Account or other Right to Payment; provided that no such disclosure shall be
required where the Disclosure Event arises in the ordinary course of business,
according to normal trade practices utilized by the Borrower and where the
amount of the Account or Right to Payment affected by such Disclosure Events is
less than $500,000 individually or in the aggregate does not exceed $2,000,000

                 (v)  in accordance with its sound business judgment perform

                 (vi)  upon the request of the Agent (A) at any time, notify
all or any designated portion of the account debtors and other obligors on the
Rights to Payment of the security interest hereunder, and (B) upon the
occurrence of an Event of Default, notify the account debtors and other
obligors on the Rights to Payment or any designated portion thereof that
payment shall be made directly to the Agent or to such other Person or location
as the Agent shall specify; and

                 (vii)  upon the occurrence of any Event of Default, establish
such lockbox or similar arrangements for the payment of the Accounts and other
Rights to Payment as the Agent shall require.

                 (n)      Documents, Etc.  Upon the request of the Agent, the
Borrower will (i) immediately deliver to the Agent, or an agent designated by
it, appropriately endorsed or accompanied by appropriate instruments of

Person on any such basis.

                 (p)  Notices, Reports and Information.  The Borrower will (i)
notify the Agent of any material claim made or asserted against the Collateral
by any Person and of any change in the composition of the Collateral or other
event which could materially adversely affect the value of the Collateral or
the Agent's Lien thereon; (ii) furnish to the Agent such statements and
schedules further identifying and describing the Collateral and such other
reports and other information in connection with the Collateral as the Agent
may reasonably request, all in reasonable detail; and (iii) upon request of the
Agent make such demands and requests for information and reports as the
Borrower is entitled to make in respect of the Collateral.

                 SECTION 6  Collection of Rights to Payment.  Until the Agent
exercises its rights hereunder to collect Rights to Payment, the Borrower shall
endeavor in the first instance diligently to collect all amounts due or to
become due on or with respect to the Rights to Payment.  At the request of the

and lawful attorney-in-fact, with full power and authority to:

                 (iv)  notify the U.S. Postal Service and other postal

Borrower to such address as the Agent may designate; and, without limiting the

representing collections on the Rights to Payment directly to the Agent;

                 (xi)  ask, demand, collect, receive and give acquittances and
receipts for any and all Rights to Payment, enforce payment or any other rights
in respect of the Rights to Payment and other Collateral, grant consents, agree
to any amendments, modifications or waivers of the agreements and documents
governing the Rights to Payment and other Collateral, and otherwise file any
claims, take any action or institute, defend, settle or adjust any actions,
suits or proceedings with respect to the Collateral, as the Agent may deem

collect the Collateral or to enforce the rights of the Agent with respect to
the Collateral;

                 (xii)  execute any and all endorsements, assignments or other
documents and instruments necessary to sell, lease, assign, convey or otherwise
transfer title in or dispose of the Collateral; and

                 (xiii)  execute any and all such other documents and
instruments, and do any and all acts and things for and on behalf of the
Borrower, which the Agent may deem necessary or advisable to maintain, protect,
realize upon and preserve the Collateral and the Agent's security interest
therein and to accomplish the purposes of this Agreement.

                 The Agent agrees that, except upon and after the occurrence of
an Event of Default, it shall not exercise the power of attorney granted to
Agent pursuant to clauses (ii) through (xii).  The foregoing power of attorney
is coupled with an interest and irrevocable so





                                      J-11
<PAGE>   186
long as the Banks have any Commitments or the Secured Obligations have not been
paid and performed in full.  The Borrower hereby ratifies, to the extent
permitted by law, all that the Agent shall lawfully and in good faith do or
cause to be done by virtue of and in compliance with this Section 7.

                 SECTION 8  Agent Performance of Borrower Obligations.  The
Agent may perform or pay any obligation which the Borrower has agreed to
perform or pay under or in connection with this Agreement, and the Borrower
shall reimburse the Agent on demand for any amounts paid by the Agent pursuant
to this Section 8.

                 SECTION 9  Agent's Duties.  Notwithstanding any provision
contained in this Agreement, the Agent shall have no duty to exercise any of
the rights, privileges or powers afforded to it and shall not be responsible to
the Borrower or any other Person for any failure to do so or delay in doing so.
Beyond the exercise of reasonable care to assure the safe custody of Collateral
in the Agent's possession and the accounting for moneys actually received by
the Agent hereunder, the Agent shall have no duty or liability to exercise or
preserve any rights, privileges or powers pertaining to the Collateral.

                 SECTION 10  Remedies.

                 (a)      Remedies.  Upon the occurrence of any Event of
Default, the Agent shall have, in addition to all other rights and remedies
granted to it in this Agreement, the Credit Agreement or any other Loan
Document, all rights and remedies of a secured party under the UCC and other
applicable laws.  Without limiting the generality of the foregoing, the
Borrower agrees that:

                 (i)  The Agent may peaceably and without notice enter any
premises of the Borrower, take possession of any Collateral, remove or dispose
of all or part of the Collateral on any premises of the Borrower or elsewhere,
and otherwise collect, receive, appropriate and realize upon all or any part of
the Collateral, and demand, give receipt for, settle, renew, extend, exchange,
compromise, adjust, or sue for all or any part of the Collateral, as the Agent
may determine.

                 (ii)  The Agent may require the Borrower to assemble all or
any part of the Collateral and make it available to the Agent, at any place and
time designated by the Agent.

                 (iii)  The Agent may secure the appointment of a receiver of
the Collateral or any part thereof (to the extent and in the manner provided by
applicable law).

                 (iv)  The Agent may withdraw (or cause to be withdrawn) any
and all funds from Deposit Accounts.

                 (v)  The Agent may sell, resell, lease, use, assign, transfer
or otherwise dispose of any or all of the Collateral in its then condition or
following any commercially reasonable preparation or processing (utilizing in
connection therewith any of the Borrower's assets, without charge or liability
to the Agent therefor) at public or private sale, by one or more





                                      J-12
<PAGE>   187
contracts, in one or more parcels, at the same or different times, for cash or
credit or for future delivery without assumption of any credit risk, all as the
Agent deems advisable; provided, however, that the Borrower shall be credited
with the net proceeds of sale only when such proceeds are finally collected by
the Agent.  The Agent and each of the Banks shall have the right upon any such
public sale, and, to the extent permitted by law, upon any such private sale,
to purchase the whole or any part of the Collateral so sold, free of any right
or equity of redemption, which right or equity of redemption the Borrower
hereby releases, to the extent permitted by law.  The Borrower hereby agrees
that the sending of notice by ordinary mail, postage prepaid, to the address of
the Borrower set forth in the Credit Agreement, of the place and time of any
public sale or of the time after which any private sale or other intended
disposition is to be made, shall be deemed reasonable notice thereof if such
notice is sent ten days prior to the date of such sale or other disposition or
the date on or after which such sale or other disposition may occur, provided
that the Agent may provide the Borrower shorter notice or no notice, to the
extent permitted by the UCC or other applicable law.

                 (b)      Proceeds Account.  To the extent that any of the
Secured Obligations may be contingent, unmatured or unliquidated (including
with respect to undrawn amounts under the Letters of Credit) at such time as
there may exist an Event of Default, the Agent may, at its election, (i) retain
the proceeds of any sale, collection, disposition or other realization upon the
Collateral (or any portion thereof) in a special purpose non-interest-bearing
restricted deposit account (the "Proceeds Account") created and maintained by
the Agent for such purpose (which shall constitute a Deposit Account included
within the Collateral hereunder) until such time as the Agent may elect to
apply such proceeds to the Secured Obligations, and the Borrower agrees that
such retention of such proceeds by the Agent shall not be deemed strict
foreclosure with respect thereto; (ii) in any manner elected by the Agent,
estimate the liquidated amount of any such contingent, unmatured or
unliquidated claims and apply the proceeds of the Collateral against such
amount; or (iii) otherwise proceed in any manner permitted by applicable law.
The Borrower agrees that the Proceeds Account shall be a blocked account and
that upon the irrevocable deposit of funds into the Proceeds Account, the
Borrower shall not have any right of withdrawal with respect to such funds.
Accordingly, the Borrower irrevocably waives until the termination of this
Agreement in accordance with Section 22 the right to make any withdrawal from
the Proceeds Account and the right to instruct the Agent to honor drafts
against the Proceeds Account.

                 (c)      Application of Proceeds.  Subject to subsection (b),
the cash proceeds actually received from the sale or other disposition or
collection of Collateral, and any other amounts received in respect of the
Collateral the application of which is not otherwise provided for herein, shall
be applied as directed by the Agent and the Majority Banks in their sole
discretion.  Any surplus thereof which exists after payment and performance in
full of the Secured Obligations shall be promptly paid over to the Borrower or
otherwise disposed of in accordance with the UCC or other applicable law.  The
Borrower shall remain liable to the Agent and the Banks for any deficiency
which exists after any sale or other disposition or collection of Collateral.





                                      J-13
<PAGE>   188
                 SECTION 11  Certain Waivers.  The Borrower waives, to the
fullest extent permitted by law, (i) any right of redemption with respect to
the Collateral, whether before or after sale hereunder, and all rights, if any,
of marshalling of the Collateral or other collateral or security for the
Secured Obligations; (ii) any right to require the Agent or the Banks (A) to
proceed against any Person, (B) to exhaust any other collateral or security for
any of the Secured Obligations, (C) to pursue any remedy in the Agent's or any
of the Banks' power, or (D) to make or give any presentments, demands for
performance, notices of nonperformance, protests, notices of protests or
notices of dishonor in connection with any of the Collateral; and (iii) all
claims, damages, and demands against the Agent or the Banks arising out of the
repossession, retention, sale or application of the proceeds of any sale of the
Collateral.

                 SECTION 12  Notices.  All notices or other communications
hereunder shall be given in the manner and to the addresses specified in the
Credit Agreement.  All such notices and other communications shall be effective
(i) if delivered by hand, when delivered; (ii) if sent by mail, upon the
earlier of the date of receipt or five Business Days after deposit in the mail,
first class  (or air mail, with respect to communications to be sent to or from
the United States), postage prepaid; and (iii) if sent by facsimile
transmission, when sent.

                 SECTION 13  No Waiver; Cumulative Remedies.  No failure on the
part of the Agent or any Bank to exercise, and no delay in exercising, any
right, remedy, power or privilege hereunder shall operate as a waiver thereof,
nor shall any single or partial exercise of any such right, remedy, power or
privilege preclude any other or further exercise thereof or the exercise of any
other right, remedy, power or privilege.  The rights and remedies under this
Agreement are cumulative and not exclusive of any rights, remedies, powers and
privileges that may otherwise be available to the Agent or any Bank.

                 SECTION 14  Costs and Expenses; Indemnification; Other
Charges.

                 (a)  Costs and Expenses.  The Borrower agrees to pay on
demand:

                 (i)  the reasonable out-of-pocket costs and expenses of the
Agent and any of its Affiliates, and the reasonable fees and disbursements of
counsel to the Agent (including allocated costs of internal counsel), in
connection with the negotiation, preparation, execution, delivery and
administration of this Agreement, and any amendments, modifications or waivers
of the terms thereof, and the custody of the Collateral;

                 (ii)  all title, appraisal (including the allocated costs of
internal appraisal services), survey, audit, consulting, search, recording,
filing and similar fees, costs and expenses incurred or sustained by the Agent
or any of its Affiliates in connection with this Agreement or the Collateral;
and

                 (iii)  all costs and expenses of the Agent, its Affiliates,
and the Banks, and the fees and disbursements of counsel (including the
allocated costs of internal counsel), in connection with the enforcement or
attempted enforcement of, and preservation of any rights or interests under,
this Agreement, any out-of-court workout or other refinancing or restructuring
or in any bankruptcy case, and the protection, sale or collection of, or other
realization





                                      J-14
<PAGE>   189
upon, any of the Collateral, including all expenses of taking, collecting,
holding, sorting, handling, preparing for sale, selling, or the like, and other
such expenses of sales and collections of Collateral, and any and all losses,
costs and expenses sustained by the Agent and any Bank as a result of any
failure by the Borrower to perform or observe its obligations contained herein.

                 (b)      Indemnification.  The Borrower hereby agrees to
indemnify the Agent and each Bank, any Affiliate thereof, and their respective
directors, officers, employees, agents, counsel and other advisors (each an
"Indemnified Person") against, and hold each of them harmless from, any and all
liabilities, obligations, losses, claims, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements of any kind or nature
whatsoever, including the reasonable fees and disbursements of counsel to an
Indemnified Person (including allocated costs of internal counsel), which may
be imposed on, incurred by, or asserted against any Indemnified Person, in any
way relating to or arising out of this Agreement or the transactions
contemplated hereby or any action taken or omitted to be taken by it hereunder
(the "Indemnified Liabilities"); provided that the Borrower shall not be liable
to any Indemnified Person for any portion of such Indemnified Liabilities to
the extent they are found by a final decision of a court of competent
jurisdiction to have resulted from such Indemnified Person's gross negligence
or willful misconduct.  If and to the extent that the foregoing indemnification
is for any reason held unenforceable, the Borrower agrees to make the maximum
contribution to the payment and satisfaction of each of the Indemnified
Liabilities which is permissible under applicable law.

                 (c)      Other Charges.  The Borrower agrees to indemnify the
Agent and each of the Banks against and hold each of them harmless from any and
all present and future stamp, transfer, documentary and other such taxes,
levies, fees, assessments and other charges made by any jurisdiction by reason
of the execution, delivery, performance and enforcement of this Agreement.

                 (d)  Interest. Any amounts payable to the Agent or any Bank
under this Section 14 or otherwise under this Agreement if not paid upon demand
shall bear interest from the date of such demand until paid in full, at the
rate of interest set forth in Section 2.09(c) of the Credit Agreement.

                 SECTION 15  Binding Effect.  This Agreement shall be binding
upon, inure to the benefit of and be enforceable by the Borrower, the Agent,
and each Bank and their respective successors and assigns.

                 SECTION 16  Governing Law.  THIS AGREEMENT SHALL BE GOVERNED
BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAW OF THE STATE OF CALIFORNIA,
EXCEPT AS REQUIRED BY MANDATORY PROVISIONS OF LAW AND TO THE EXTENT THE
VALIDITY OR PERFECTION OF THE SECURITY INTERESTS HEREUNDER, OR THE REMEDIES
HEREUNDER, IN RESPECT OF ANY COLLATERAL ARE GOVERNED BY THE LAW OF A
JURISDICTION OTHER THAN CALIFORNIA.

<PAGE>   190
                 SECTION 17  Entire Agreement; Amendment.  This Agreement
contains the entire agreement of the parties with respect to the subject matter
hereof and shall not be amended except by the written agreement of the parties
as provided in the Credit Agreement.

                 SECTION 18  Severability.  Whenever possible, each provision
of this Agreement shall be interpreted in such manner as to be effective and
valid under all applicable laws and regulations.  If, however, any provision of
this Agreement shall be prohibited by or invalid under any such law or
regulation in any jurisdiction, it shall, as to such jurisdiction, be deemed
modified to conform to the minimum requirements of such law or regulation, or,
if for any reason it is not deemed so modified, it shall be ineffective and
invalid only to the extent of such prohibition or invalidity without affecting
the remaining provisions of this Agreement, or the validity or effectiveness of
such provision in any other jurisdiction.

                 SECTION 19  Counterparts.  This Agreement may be executed in
any number of counterparts and by different parties hereto in separate
counterparts, each of which when so executed shall be deemed to be an original
and all of which taken together shall constitute but one and the same
agreement.

                 SECTION 20  Incorporation of Provisions of the Credit
Agreement.  To the extent the Credit Agreement contains provisions of general
applicability to the Loan Documents, including any such provisions contained in
Article XI thereof, such provisions are incorporated herein by this reference.

                 SECTION 21  No Inconsistent Requirements.  The Borrower
acknowledges that this Agreement and the other Loan Documents may contain
covenants and other terms and provisions variously stated regarding the same or
similar matters, and agrees that all such covenants, terms and provisions are
cumulative and all shall be performed and satisfied in accordance with their
respective terms.

                 SECTION 22  Termination.  Upon the termination of the
Commitments of the Banks, the surrender of the Letters of Credit and payment
and performance in full of all Secured Obligations, this Agreement shall
terminate and the Agent shall promptly execute and deliver to the Borrower such
documents and instruments reasonably requested by the Borrower as shall be
necessary to evidence termination of all security interests given by the
Borrower to the Agent hereunder; provided, however, that the obligations of the
Borrower under Section 14 shall survive such termination.

                 (p)  Notices, Reports and Information.  The Subsidiary will
(i) notify the Agent of any material claim made or asserted against the
Collateral by any Person and of any change in the composition of the Collateral
or other event which could materially adversely affect the value of the
Collateral or the Agent's Lien thereon; (ii) furnish to the Agent such
statements and schedules further identifying and describing the Collateral and
such other reports and other information in connection with the Collateral as
the Agent may reasonably request, all in reasonable detail; and (iii) upon
request of the Agent make such demands and requests for information and reports
as the Subsidiary is entitled to make in respect of the Collateral.

                 SECTION 6  Collection of Rights to Payment.  Until the Agent
exercises its rights hereunder to collect Rights to Payment, the Subsidiary
shall endeavor in the first instance diligently to collect all amounts due or
to become due on or with respect to the Rights to Payment.  At the request of
the Agent, upon and after the occurrence of any Event of Default, all
remittances received by the Subsidiary shall be held in trust for the Agent
and, in accordance with the Agent's instructions, remitted to the Agent or
deposited to an account with the Agent in the form received (with any necessary
endorsements or instruments of assignment or transfer).

                 SECTION 7  Authorization; Agent Appointed Attorney-in-Fact.
The Agent shall have the right to, in the name of the Subsidiary, or in the
name of the Agent or otherwise, without notice to or assent by the Subsidiary,
and the Subsidiary hereby constitutes and appoints the Agent (and any of the
Agent's officers or employees or agents designated by the Agent) as the
Subsidiary's true and lawful attorney-in-fact, with full power and authority
to:

                 (iii)  sign and endorse any invoice or bill of lading relating
to any of the Collateral, warehouse or storage receipts, drafts against
customers or other obligors, assignments, notices of assignment, verifications
and notices to customers or other obligors;

                 (iv)  notify the U.S. Postal Service and other postal
authorities to change the address for delivery of mail addressed to the
Subsidiary to such address as the Agent may designate; and, without limiting
the generality of the foregoing, establish with any Person lockbox or similar
arrangements for the payment of the Rights to Payment;

                 (v)  receive, open and dispose of all mail addressed to the
Subsidiary;

                 (vi)  send requests for verification of Rights to Payment to
the customers or other obligors of the Subsidiary;

                 (vii)  contact, or direct the Subsidiary to contact, all
account debtors and other obligors on the Rights to Payment and instruct such
account debtors and other obligors to make all payments directly to the Agent;

                 (viii)  assert, adjust, sue for, compromise or release any
claims under any policies of insurance;

                 (ix)  exercise dominion and control over, and refuse to permit
further withdrawals from, Deposit Accounts maintained with the Agent, any Bank

arrangements for the payment of the Rights to Payment to remit all amounts
representing collections on the Rights to Payment directly to the Agent;

                 (xi)  ask, demand, collect, receive and give acquittances and
receipts for any and all Rights to Payment, enforce payment or any other rights
in respect of the Rights to Payment and other Collateral, grant consents, agree
to any amendments, modifications or waivers of the agreements and documents
governing the Rights to Payment and other Collateral, and otherwise file any
claims, take any action or institute, defend, settle or adjust any actions,
suits or proceedings with respect to the Collateral, as the Agent may deem
necessary or desirable to maintain, preserve and protect the Collateral, to
collect the Collateral or to enforce the rights of the Agent with respect to
the Collateral;



                                      K-11
<PAGE>   205
                 (xii)  execute any and all endorsements, assignments or other
documents and instruments necessary to sell, lease, assign, convey or otherwise
transfer title in or dispose of the Collateral; and

                 (xiii)  execute any and all such other documents and
instruments, and do any and all acts and things for and on behalf of the
Subsidiary, which the Agent may deem necessary or advisable to maintain,
protect, realize upon and preserve the Collateral and the Agent's security
interest therein and to accomplish the purposes of this Agreement.

                 The Agent agrees that, except upon and after the occurrence of
an Event of Default, it shall not exercise the power of attorney granted to
Agent pursuant to clauses (ii) through (xii).  The foregoing power of attorney
is coupled with an interest and irrevocable so long as the Banks have any
Commitments or the Secured Obligations have not been paid and performed in
full.  The Subsidiary hereby ratifies, to the extent permitted by law, all that
the Agent shall lawfully and in good faith do or cause to be done by virtue of
and in compliance with this Section 7.

                 SECTION 8  Agent Performance of Subsidiary Obligations.  The
Agent may perform or pay any obligation which the Subsidiary has agreed to
perform or pay under or in connection with this Agreement, and the Subsidiary
shall reimburse the Agent on demand for any amounts paid by the Agent pursuant
to this Section 8.

                 SECTION 9  Agent's Duties.  Notwithstanding any provision
contained in this Agreement, the Agent shall have no duty to exercise any of
the rights, privileges or powers afforded to it and shall not be responsible to
the Subsidiary or any other Person for any failure to do so or delay in doing
so.  Beyond the exercise of reasonable care to assure the safe custody of
Collateral in the Agent's possession and the accounting for moneys actually
received by the Agent hereunder, the Agent shall have no duty or liability to
exercise or preserve any rights, privileges or powers pertaining to the
Collateral.

                 SECTION 10  Remedies.

                 (a)      Remedies.  Upon the occurrence of any Event of
Default, the Agent shall have, in addition to all other rights and remedies
granted to it in this Agreement, the Credit Agreement or any other Loan
Document, all rights and remedies of a secured party under the UCC and other
applicable laws.  Without limiting the generality of the foregoing, the
Subsidiary agrees that:

                 (i)  The Agent may peaceably and without notice enter any
premises of the Subsidiary, take possession of any Collateral, remove or
dispose of all or part of the Collateral on any premises of the Subsidiary or
elsewhere, and otherwise collect, receive, appropriate and realize upon all or
any part of the Collateral, and demand, give receipt for, settle, renew,
extend, exchange, compromise, adjust, or sue for all or any part of the
Collateral, as the Agent may determine.

<PAGE>   206
                 (ii)  The Agent may require the Subsidiary to assemble all or
any part of the Collateral and make it available to the Agent, at any place and
time designated by the Agent.

                 (iii)  The Agent may secure the appointment of a receiver of
the Collateral or any part thereof (to the extent and in the manner provided by
applicable law).

                 (iv)  The Agent may withdraw (or cause to be withdrawn) any
and all funds from Deposit Accounts.

                 (v)  The Agent may sell, resell, lease, use, assign, transfer
or otherwise dispose of any or all of the Collateral in its then condition or
following any commercially reasonable preparation or processing (utilizing in
connection therewith any of the Subsidiary's assets, without charge or
liability to the Agent therefor) at public or private sale, by one or more
contracts, in one or more parcels, at the same or different times, for cash or
credit or for future delivery without assumption of any credit risk, all as the
Agent deems advisable; provided, however, that the Subsidiary shall be credited
with the net proceeds of sale only when such proceeds are finally collected by
the Agent.  The Agent and each of the Banks shall have the right upon any such
public sale, and, to the extent permitted by law, upon any such private sale,
to purchase the whole or any part of the Collateral so sold, free of any right
or equity of redemption, which right or equity of redemption the Subsidiary
hereby releases, to the extent permitted by law.  The Subsidiary hereby agrees
that the sending of notice by ordinary mail, postage prepaid, to the address of
the Subsidiary set forth in the Credit Agreement, of the place and time of any
public sale or of the time after which any private sale or other intended
disposition is to be made, shall be deemed reasonable notice thereof if such
notice is sent ten days prior to the date of such sale or other disposition or
the date on or after which such sale or other disposition may occur, provided
that the Agent may provide the Subsidiary shorter notice or no notice, to the
extent permitted by the UCC or other applicable law.

                 (b)      Proceeds Account.  To the extent that any of the
Secured Obligations may be contingent, unmatured or unliquidated (including
with respect to undrawn amounts under the Letters of Credit) at such time as
there may exist an Event of Default, the Agent may, at its election, (i) retain
the proceeds of any sale, collection, disposition or other realization upon the
Collateral (or any portion thereof) in a special purpose non-interest-bearing
restricted deposit account (the "Proceeds Account") created and maintained by
the Agent for such purpose (which shall constitute a Deposit Account included
within the Collateral hereunder) until such time as the Agent may elect to
apply such proceeds to the Secured Obligations, and the Subsidiary agrees that
such retention of such proceeds by the Agent shall not be deemed strict
foreclosure with respect thereto; (ii) in any manner elected by the Agent,
estimate the liquidated amount of any such contingent, unmatured or
unliquidated claims and apply the proceeds of the Collateral against such
amount; or (iii) otherwise proceed in any manner permitted by applicable law.
The Subsidiary agrees that the Proceeds Account shall be a blocked account and
that upon the irrevocable deposit of funds into the Proceeds Account, the
Subsidiary shall not have any right of withdrawal with respect to such funds.
Accordingly, the Subsidiary irrevocably waives until the termination of this
Agreement in accordance with Section 22 the right to make any withdrawal from
the Proceeds Account and the right to instruct the Agent to honor drafts
against the Proceeds Account.

<PAGE>   207
                 (c)      Application of Proceeds.  Subject to subsection (b),
the cash proceeds actually received from the sale or other disposition or
collection of Collateral, and any other amounts received in respect of the
Collateral the application of which is not otherwise provided for herein, shall
be applied as directed by the Agent and the Majority Banks in their sole
discretion.  Any surplus thereof which exists after payment and performance in
full of the Secured Obligations shall be promptly paid over to the Subsidiary
or otherwise disposed of in accordance with the UCC or other applicable law.
The Subsidiary shall remain liable to the Agent and the Banks for any
deficiency which exists after any sale or other disposition or collection of
Collateral.

                 SECTION 11  Certain Waivers.  The Subsidiary waives, to the
fullest extent permitted by law, (i) any right of redemption with respect to
the Collateral, whether before or after sale hereunder, and all rights, if any,
of marshalling of the Collateral or other collateral or security for the
Secured Obligations; (ii) any right to require the Agent or the Banks (A) to
proceed against any Person, (B) to exhaust any other collateral or security for
any of the Secured Obligations, (C) to pursue any remedy in the Agent's or any
of the Banks' power, or (D) to make or give any presentments, demands for
performance, notices of nonperformance, protests, notices of protests or
notices of dishonor in connection with any of the Collateral; and (iii) all
claims, damages, and demands against the Agent or the Banks arising out of the
repossession, retention, sale or application of the proceeds of any sale of the
Collateral.

                 SECTION 12  Notices.  All notices or other communications
hereunder shall be given in the manner and to the addresses specified in the
Credit Agreement.  All such notices and other communications shall be effective
(i) if delivered by hand, when delivered; (ii) if sent by mail, upon the
earlier of the date of receipt or five Business Days after deposit in the mail,
first class  (or air mail, with respect to communications to be sent to or from
the United States), postage prepaid; and (iii) if sent by facsimile
transmission, when sent.

                 SECTION 13  No Waiver; Cumulative Remedies.  No failure on the
part of the Agent or any Bank to exercise, and no delay in exercising, any
right, remedy, power or privilege hereunder shall operate as a waiver thereof,
nor shall any single or partial exercise of any such right, remedy, power or
privilege preclude any other or further exercise thereof or the exercise of any
other right, remedy, power or privilege.  The rights and remedies under this
Agreement are cumulative and not exclusive of any rights, remedies, powers and
privileges that may otherwise be available to the Agent or any Bank.

                 SECTION 14  Costs and Expenses; Indemnification; Other
Charges.

                 (a)  Costs and Expenses.  The Subsidiary agrees to pay on
demand:

                 (i)  the reasonable out-of-pocket costs and expenses of the
Agent and any of its Affiliates, and the reasonable fees and disbursements of
counsel to the Agent (including allocated costs of internal counsel), in
connection with the negotiation, preparation, execution, delivery and
administration of this Agreement, and any amendments, modifications or waivers
of the terms thereof, and the custody of the Collateral;



                                      K-14
<PAGE>   208
                 (ii)  all title, appraisal (including the allocated costs of
internal appraisal services), survey, audit, consulting, search, recording,
filing and similar fees, costs and expenses incurred or sustained by the Agent
or any of its Affiliates in connection with this Agreement or the Collateral;
and

                 (iii)  all costs and expenses of the Agent, its Affiliates,
and the Banks, and the fees and disbursements of counsel (including the
allocated costs of internal counsel), in connection with the enforcement or
attempted enforcement of, and preservation of any rights or interests under,
this Agreement, any out-of-court workout or other refinancing or restructuring
or in any bankruptcy case, and the protection, sale or collection of, or other
realization upon, any of the Collateral, including all expenses of taking,
collecting, holding, sorting, handling, preparing for sale, selling, or the
like, and other such expenses of sales and collections of Collateral, and any
and all losses, costs and expenses sustained by the Agent and any Bank as a
result of any failure by the Subsidiary to perform or observe its obligations
contained herein.

                 (b)      Indemnification.  The Subsidiary hereby agrees to
indemnify the Agent and each Bank, any Affiliate thereof, and their respective
directors, officers, employees, agents, counsel and other advisors (each an
"Indemnified Person") against, and hold each of them harmless from, any and all
liabilities, obligations, losses, claims, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements of any kind or nature
whatsoever, including the reasonable fees and disbursements of counsel to an
Indemnified Person (including allocated costs of internal counsel), which may
be imposed on, incurred by, or asserted against any Indemnified Person, in any
way relating to or arising out of this Agreement or the transactions
contemplated hereby or any action taken or omitted to be taken by it hereunder
(the "Indemnified Liabilities"); provided that the Subsidiary shall not be
liable to any Indemnified Person for any portion of such Indemnified
Liabilities to the extent they are found by a final decision of a court of
competent jurisdiction to have resulted from such Indemnified Person's gross
negligence or willful misconduct.  If and to the extent that the foregoing
indemnification is for any reason held unenforceable, the Subsidiary agrees to
make the maximum contribution to the payment and satisfaction of each of the
Indemnified Liabilities which is permissible under applicable law.

                 (c)      Other Charges.  The Subsidiary agrees to indemnify
the Agent and each of the Banks against and hold each of them harmless from any
and all present and future stamp, transfer, documentary and other such taxes,
levies, fees, assessments and other charges made by any jurisdiction by reason
of the execution, delivery, performance and enforcement of this Agreement.

                 (d)  Interest. Any amounts payable to the Agent or any Bank
under this Section 14 or otherwise under this Agreement if not paid upon demand
shall bear interest from the date of such demand until paid in full, at the
rate of interest set forth in Section 2.09(c) of the Credit Agreement.

                 SECTION 15  Binding Effect.  This Agreement shall be binding
upon, inure to the benefit of and be enforceable by the Subsidiary, the Agent,
and each Bank and their respective successors and assigns.

                 SECTION 16  Governing Law.  THIS AGREEMENT SHALL BE GOVERNED
BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAW OF THE STATE OF CALIFORNIA,
EXCEPT AS REQUIRED BY MANDATORY PROVISIONS OF LAW AND TO THE EXTENT THE
VALIDITY OR PERFECTION OF THE SECURITY INTERESTS HEREUNDER, OR THE REMEDIES
HEREUNDER, IN RESPECT OF ANY COLLATERAL ARE GOVERNED BY THE LAW OF A
JURISDICTION OTHER THAN CALIFORNIA.

                 SECTION 17  Entire Agreement; Amendment.  This Agreement
contains the entire agreement of the parties with respect to the subject matter
hereof and shall not be amended except by the written agreement of the parties
as provided in the Credit Agreement.

                 SECTION 18  Severability.  Whenever possible, each provision
of this Agreement shall be interpreted in such manner as to be effective and
valid under all applicable laws and regulations.  If, however, any provision of
this Agreement shall be prohibited by or invalid under any such law or
regulation in any jurisdiction, it shall, as to such jurisdiction, be deemed
modified to conform to the minimum requirements of such law or regulation, or,
if for any reason it is not deemed so modified, it shall be ineffective and
invalid only to the extent of such prohibition or invalidity without affecting
the remaining provisions of this Agreement, or the validity or effectiveness of
such provision in any other jurisdiction.

                 SECTION 19  Counterparts.  This Agreement may be executed in
any number of counterparts and by different parties hereto in separate
counterparts, each of which when so executed shall be deemed to be an original
and all of which taken together shall constitute but one and the same
agreement.

                 SECTION 20  Incorporation of Provisions of the Credit
Agreement.  To the extent the Credit Agreement contains provisions of general
applicability to the Loan Documents, including any such provisions contained in
Article XI thereof, such provisions are incorporated herein by this reference.

                 SECTION 21  No Inconsistent Requirements.  The Subsidiary
acknowledges that this Agreement and the other Loan Documents may contain
covenants and other terms and provisions variously stated regarding the same or
similar matters, and agrees that all such covenants, terms and provisions are
cumulative and all shall be performed and satisfied in accordance with their
respective terms.

                 SECTION 22  Termination.  Upon the termination of the
Commitments of the Banks, the surrender of the Letters of Credit and payment
and performance in full of all Secured Obligations, this Agreement shall
terminate and the Agent shall promptly execute and deliver to the Subsidiary
such documents and instruments reasonably requested by the Subsidiary as shall
be necessary to evidence termination of all security interests given by the





                                      K-16
<PAGE>   210
Subsidiary to the Agent hereunder; provided, however, that the obligations of
the Subsidiary under Section 14 shall survive such termination.

                 IN WITNESS WHEREOF, the parties hereto have duly executed this
Agreement, as of the date first above written.
