                              FINANCIAL STATEMENTS

Note 1.    The consolidated balance sheets, consolidated statements of income
           and consolidated statements of cash flows are unaudited as of and for
           the three months and six months ended June 29, 1996 and July 1, 1995.
           The financial information included in the quarterly report should be
           read in conjunction with the Company's consolidated financial
           statements and the related notes thereto included in its annual
           report to shareholders for the year ended December 31, 1995.

Note 2.    Certain amounts and disclosures included in the consolidated
           financial statements required management to make estimates which
           could differ from actual results.

Note 3.    Earnings per common share computations are based on the weighted
           average number of common and common equivalent shares outstanding in
           each period. Common equivalent shares represent the number of shares
           which would be issued assuming the exercise of dilutive stock
           options, reduced by the number of shares which would be purchased
           with the proceeds from the exercise of such options. For 1996 and
           1995, shares associated with convertible securities have been
           included in the weighted average number of shares outstanding. The
           computations of earnings per share are as follows:

Note 4.    Acquisition

           In January 1995, Ducommun acquired the capital stock of 3dbm, Inc.
           ("3dbm") for $4,780,000 in cash (of which $353,000 was withheld with
           respect to certain assets and potential liabilities of 3dbm) and
           $400,000 in notes. 3dbm supplies high-power expanders, microcells and
           other wireless communications hardware used in cellular telephone
           networks, and microwave components and subsystems to both military
           and commercial customers.

           On June 28, 1996, Ducommun acquired substantially all of the assets
           and assumed certain liabilities of MechTronics of Arizona, Inc.
           ("MechTronics") for $8,000,000 in cash and a $750,000 note. Ducommun
           may be required to make additional payments for the period June 28,
           1996 to December 31, 1996, and each of the calendar years ending
           December 31, 1997, 1998, and 1999, based on the future financial
           performance of the business of MechTronics. MechTronics is one of the
           United States' leading manufacturers of high quality and high
           reliability mechanical and electromechanical enclosure products for
           the defense electronics, commercial aviation and communications
           markets.

           The acquisition of MechTronics was accounted for under the purchase
           method of accounting. However, the consolidated statements of income
           do not include any operating results for MechTronics, since the
           acquisition was not completed until June 28, 1996. The cost of the
           acquisition has been preliminarily allocated on the basis of the
           estimated fair value of assets acquired and liabilities assumed. This
           resulted in approximately $2,203,000 of cost in excess of net assets
           acquired. Such excess (which will increase for any future contingent
           payments) is being amortized on a straight line basis over fifteen
           years.

</TABLE>

           During the first six months of 1996, the Company issued 2,417,205 new
           shares of common stock upon conversion of $24,263,000 of its
           outstanding 7.75% convertible subordinated debentures. The Company
           paid cash of $609,000 for the conversions. The conversions reduced
           interest expense by approximately $324,000 in the first six months of
           1996.

           In May 1996, the Company and its bank amended the Company's credit
           agreement. The amended credit agreement provides for a $24,000,000
           line of credit at May 16, 1996. The line of credit has an expiration
           date of July 1, 1998. Interest is payable monthly on the outstanding
           borrowings based on the bank's prime rate (8.25% at June 29, 1996). A
           Eurodollar pricing option is also available to the Company for terms
           of up to six months at the Eurodollar rate plus a spread based on the
           leverage ratio of the Company calculated at the end of each fiscal
           quarter (1.50% to 1.75% at June 29, 1996). At June 29, 1996, the
           Company had $9,158,000 of unused lines of credit, after deducting
           $14,500,000 of loans outstanding and $342,000 for an outstanding
           standby letter of credit which supports the estimated post-closure
           maintenance cost for a former surface impoundment.

           Borrowings under the credit agreement are secured by most of the
           assets of the Company and its subsidiaries. The credit agreement
           includes minimum leverage and fixed charge coverage ratios, earnings
           covenants, and limitations on capital expenditures, acquisitions,
           future dividend payments and outside indebtedness.

</TABLE>

The decrease in the valuation allowance is due to the Company's reevaluation of
the realizability of income tax benefits from future operations related to the
acquisition of MechTronics consummated in June 1996. As a result, the carrying
value of the net deferred tax benefit was increased by $665,000 and goodwill
associated with the MechTronics acquisition was reduced by the same amount.

At June 29, 1996, the Company had federal tax NOLs totalling $27 million which
expire in the years 1999 through 2004. SFAS 109 requires that the tax benefit of
such NOLs be recorded, measured by enacted tax rates, as an asset to the extent
management assesses the utilization of such NOLs to be "more likely than not."
Management has determined that the income of the Company will, more likely than
not, be sufficient to realize the recorded deferred tax asset prior to the
ultimate expiration of the NOLs. Realization of the future tax benefits of NOLs
is dependent on the Company's ability to generate sufficient taxable income
within the carryforward period. In assessing the likelihood of utilization of
existing NOLs, management considered the historical results of operations of its
operating subsidiaries, including acquired operations, and the current economic
environment in which the Company operates. Management does not consider any
material future changes in trends or the relationship between reported pretax
income and federal and state taxable income or material asset sales or similar
non-routine transactions in assessing the likelihood of realization of the
recorded deferred tax asset.

Future levels of pretax income are dependent upon the extent of defense spending
and other government budgetary pressures, the level of new aircraft orders by
commercial airlines, production rate requirement for the Space Shuttle program,
general economic conditions,

                                      -13-
<PAGE>   14

         interest rates, competitive pressures on sales and margins, price
         levels and other factors beyond the Company's control.

         The ability of the Company to utilize the NOLs could be subject to
         significant limitation in the event of a "change in ownership" as
         defined in the Internal Revenue Code. A "change of ownership" could be
         caused by purchases or sales of the Company's securities owned by
         persons or groups now or in the future having ownership of 5% or more
         of the Company's outstanding common stock or issuance by the Company of
         common stock.

Note 7.  Contingencies

           Ducommun's subsidiary, Aerochem, Inc. ("Aerochem"), is a major
           supplier of chemical milling services for the aerospace industry.
           Aerochem has been directed by California environmental agencies to
           investigate and take corrective action for groundwater contamination
           at its El Mirage, California facility. Based upon currently available
           information, the Company has established a provision for the cost of
           such investigation and corrective action.

           Aerochem has been notified by the United States Environmental
           Protection Agency that Aerochem and other generators of hazardous
           waste disposed at the Casmalia Resources Hazardous Waste Facility in
           California (the "Casmalia Site"), an inactive hazardous waste
           treatment, storage and disposal facility, may be responsible for
           certain costs associated with the cleanup and closure of the Casmalia
           Site. Aerochem contributed less than 1/4 of 1% of the total waste
           disposed of at the Casmalia Site and many other substantially larger
           companies and governmental entities are involved at the Casmalia
           Site. The Company has established a provision, based on currently
           available information, for Aerochem's share of the estimated cost of
           cleanup and closure of the Casmalia Site.

           In the normal course of business, Ducommun and its subsidiaries are
           defendants in certain other litigation, claims and inquiries,
           including matters relating to environmental laws. In addition, the
           Company makes various commitments and incurs contingent liabilities.
           While it is not feasible to predict the outcome of these matters, the
           Company does not presently expect that any sum it may be required to
           pay in connection with these matters would have a material adverse
           effect on its consolidated financial position or results of
           operations.

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

FINANCIAL STATEMENT PRESENTATION

The interim financial statements reflect all adjustments, consisting only of
normal recurring adjustments, which are, in the opinion of the Company,
necessary for a fair presentation of the results for the interim periods
presented.

ACQUISITION

On June 28, 1996, Ducommun acquired substantially all of the assets and assumed
certain liabilities of MechTronics of Arizona, Inc. ("MechTronics") for
$8,000,000 in cash and $750,000 in a note. Ducommun may be required to make
additional payments for the period June 28, 1996 to December 31, 1996, and each
of the calendar years ending December 31, 1997, 1998, and 1999, based on the
future financial performance of the business of MechTronics. MechTronics is one
of the United States' leading manufacturers of high quality and high reliability
mechanical and electromechanical enclosure products for the defense electronics,
commercial aviation and communications markets.

This acquisition was funded from internally generated cash, a note payable to
the seller and borrowings under the Company's credit agreement with its bank
(see Financial Condition for additional information).

RESULTS OF OPERATIONS AND EFFECTS OF INFLATION

Second Quarter 1996 Compared to Second Quarter 1995

Net sales increased 24% to $28,869,000 in the second quarter of 1996. The
increase was primarily due to increased off-load work for aircraft structural
components from prime contractors and major subcontractors and increased build
rates for certain models of commercial jet aircraft.

The Company had substantial sales to Lockheed Martin, Northrop Grumman,
McDonnell Douglas and Boeing. During the second quarter of 1996 and 1995, sales
to Lockheed Martin were approximately $2,329,000 and $2,298,000, respectively;
sales to Northrop Grumman were approximately $2,490,000 and $2,221,000,
respectively; sales to McDonnell Douglas were approximately $2,832,000 and
$2,841,000, respectively; and sales to Boeing were approximately $4,572,000 and
$1,542,000, respectively. The sales to Lockheed Martin are primarily related to
the Space Shuttle program. The sales relating to Northrop Grumman, McDonnell
Douglas and Boeing are diversified over a number of different commercial and
military programs.


                                      -15-
<PAGE>   16
Gross profit, as a percentage of sales, was 32.6% for the second quarter of 1996
compared to 31.6% in 1995. This increase was primarily the result of change in
sales mix, economies of scale resulting from sales increases and improvements in
production efficiencies.

Selling, general and administrative expenses, as a percentage of sales,
decreased to 20.1% in 1996, compared to 21.5% of sales for 1995. This decrease
in expenses as a percentage of sales was primarily related to higher sales
volume offset by increased period costs related to the higher sales volume,
$244,000 of debt conversion expense related to the conversion of $15,837,000 of
convertible subordinated debentures and acquisition related expenses of $130,000
during the second quarter of 1996.

Interest expense decreased 72% to $275,000 in 1996 primarily due to the
conversion of $28,000,000 of convertible subordinated debentures and lower debt
levels.

The increase in income tax expense was primarily due to the increase in income
before taxes. The Company continues to use its federal net operating loss
carryforward to offset taxable income for income tax purposes. Cash expended to
pay income taxes was $618,000 in 1996, compared to $50,000 in 1995. For further
discussion relating to the income taxes, see Note 6 to the consolidated
financial statements.

Net income for the second quarter of 1996 was $2,406,000, or $0.31 per share,
compared to $970,000, or $0.18 per share, in 1995.

Six Months of 1996 Compared to Six Months of 1995

Net sales increased 20% to $52,661,000 in the first six months of 1996. The
increase was primarily due to increased off-load work for aircraft structural
components from prime contractors and major subcontractors and increased build
rates for certain models of commercial jet aircraft.

The Company had substantial sales to Lockheed Martin, Northrop Grumman,
McDonnell Douglas and Boeing. During the first six months of 1996 and 1995,
sales to Lockheed Martin were approximately $4,792,000 and $4,546,000,
respectively; sales to Northrop Grumman were approximately $4,368,000 and
$4,613,000, respectively; sales to McDonnell Douglas were approximately
$5,532,000 and $5,147,000, respectively; and sales to Boeing were approximately
$6,028,000 and $2,767,000, respectively. The sales to Lockheed Martin are
primarily related to the Space Shuttle program. The sales relating to Northrop
Grumman, McDonnell Douglas and Boeing are diversified over a number of different
commercial and military programs.

At June 29, 1996, backlog believed to be firm was approximately $117,400,000,
including $24,257,000 for space-related business, compared to $93,100,000 at
July 1, 1995 and $92,600,000 at December 31, 1995. Approximately $47,000,000 of
the total backlog is expected to be delivered during 1996.


                                      -16-
<PAGE>   17
Gross profit, as a percentage of sales, was 33.5% for the first six months of
1996 compared to 30.8% in 1995. This increase was primarily the result of change
in sales mix, economies of scale resulting from sales increases and improvements
in production efficiencies.

Selling, general and administrative expenses increased to $12,043,000, or 22.9%
of sales in 1996, compared to 21.5% of sales for 1995. The increase in expenses
as a percentage of sales was primarily the result of period costs related to
higher sales volume and $811,000 of debt conversion expense related to the
conversion of $24,263,000 of convertible subordinated debentures and acquisition
related costs.

Interest expense decreased 63% to $697,000 in 1996 primarily due to the
conversion of $24,263,000 of convertible subordinated debentures and lower debt
levels.

The increase in income tax expense was primarily due to the increase in income
before taxes. The Company continues to use its federal net operating loss
carryforwards to offset taxable income for income tax purposes. Cash expended to
pay income taxes was $1,018,000 in 1996, compared to $125,000 in 1995. For
further discussion relating to the income taxes, see Note 6 to the consolidated
financial statements.

Net income for 1996 was $3,516,000, or $0.51 per share, compared to $1,585,000,
or $0.31 per share, in 1995.

FINANCIAL CONDITION

Liquidity and Capital Resources

Cash flow from operating activities for the six months ended June 29, 1996 was
$4,515,000, of which $2,783,000 was used to purchase property and equipment.
During the first six months of 1996, the Company borrowed $8,000,000 to fund the
acquisition of MechTronics. The Company also issued 2,417,205 new shares of
common stock upon conversion of $24,263,000 of its outstanding 7.75% convertible
subordinated debentures.

The Company continues to depend on operating cash flow and the availability of
its bank line of credit to provide short-term liquidity. Cash from operations
and bank borrowing capacity are expected to provide sufficient liquidity to meet
the Company's obligations during 1996.

                                      -17-
<PAGE>   18
In May 1996, the Company and its bank amended the Company's credit agreement.
The amended credit agreement provides for a $24,000,000 line of credit at May
16, 1996. The line of credit has an expiration date of July 1, 1998. Interest is
payable monthly on the outstanding borrowings based on the bank's prime rate
(8.25% at June 29, 1996). A Eurodollar pricing option is also available to the
Company for terms of up to six months at the Eurodollar rate plus a spread based
on the leverage ratio of the Company calculated at the end of each fiscal
quarter (1.50% to 1.75% at June 29, 1996). At June 29, 1996, the Company had
$9,158,000 of unused lines of credit, after deducting $14,500,000 of loans
outstanding and $342,000 for an outstanding standby letter of credit which
supports the estimated post-closure maintenance cost for a former surface
impoundment.

The Company spent $2,783,000 on capital expenditures during the first six months
of 1996 and expects to spend less than $6,000,000 for capital expenditures in
1996.

Ducommun's subsidiary, Aerochem, Inc. ("Aerochem"), is a major supplier of
chemical milling services for the aerospace industry. Aerochem has been directed
by California environmental agencies to investigate and take corrective action
for groundwater contamination at its El Mirage, California facility. Based upon
currently available information, the Company has established a provision for the
cost of such investigation and corrective action.

Aerochem has been notified by the United States Environmental Protection Agency
that Aerochem and other generators of hazardous waste disposed at the Casmalia
Resources Hazardous Waste Facility in California (the "Casmalia Site"), an
inactive hazardous waste treatment, storage and disposal facility, may be
responsible for certain costs associated with the cleanup and closure of the
Casmalia Site. Aerochem contributed less than 1/4 of 1% of the total waste
disposed of at the Casmalia Site and many other substantially larger companies
and governmental entities are involved at the Casmalia Site. The Company has
established a provision, based on currently available information, for
Aerochem's share of the estimated cost of cleanup and closure of the Casmalia
Site.

In the normal course of business, Ducommun and its subsidiaries are defendants
in certain other litigation, claims and inquiries, including matters relating to
environmental laws. In addition, the Company makes various commitments and
incurs contingent liabilities. While it is not feasible to predict the outcome
of these matters, the Company does not presently expect that any sum it may be
required to pay in connection with these matters would have a material adverse
effect on its consolidated financial position or results of operations.

         with generally accepted accounting principles, current assets

         (excluding principal payments for that fiscal period in respect to all

In the event that generally accepted accounting principles change during the
term of this Agreement such that the financial covenants contained herein would
then be calculated in a different manner or with different components, Borrower
and Bank agree to amend this Agreement in such respects as are necessary to
conform those covenants as criteria for evaluating Borrower's financial
condition, or limiting the aggregate Loans hereunder, to substantially the same
criteria as were effective prior to such change in generally accepted accounting
principles. Without limiting the foregoing, and unless otherwise expressly
stated to the contrary, all financial covenants set forth in this Agreement and
all calculations required thereby shall be applied and calculated with respect
to the performance of Borrower and its Subsidiaries on a consolidated basis.

Agreement, at any time and from time to time from the Restated Closing Date
through the Banking Day immediately preceding the Revolver Termination Date,
Bank shall make Revolving Loans to Borrower in such amounts as Borrower may
request that do not exceed in the aggregate at any one time outstanding the Line
A Commitment; provided that except to the extent otherwise provided in Section
2.5(d), Bank shall not be obligated to make a Revolving Loan if, after giving

         2.3 Procedure for Borrowing. (a) Each Loan shall be made upon
Borrower's irrevocable written notice delivered to Bank in the form of a Request

in the case of Reference Rate Loans, in each case specifying:

                           A. the amount of the requested Loan (with respect to
         any IBOR Loan, each of which shall be in an integral multiple of
         $100,000 and not less than $500,000);

                           B. the Commitment under which the Loan will be made.

                           C. the requested Borrowing Date, which shall be a
         Banking Day;

                           D. the Type of Loan requested; and

                           E. the duration of the Interest Period applicable to
         such Loan included in such notice. If the Request for Loan fails to
         specify the duration of the

<PAGE>   26
         Interest Period for any Borrowing comprised of IBOR Loans, such
         Interest Period shall be one month.

                  (a) Unless Bank has notified, in its sole and absolute
         discretion, Borrower to the contrary, a Loan may be requested by
         telephone, telecopier or telex by Responsible Official of Borrower, in
         which case Borrower shall confirm such request by promptly mailing a
         Request for Loan conforming to the above requirements to Bank.

                  (b) Upon fulfillment of the applicable conditions set forth in
         Article 8, the proceeds of a Loan shall be credited in immediately
         available funds to the Designated Deposit Account.

                  (c) The Revolving Loans made by Bank may be evidenced by
         notations on the Revolving Line Note or by other similar written
         records. The Line B Loans made by Bank may be evidenced by notations on
         the Line B Note or by other similar written records.

                  (d) A Request for Loan shall be irrevocable upon receipt by
         Bank.

                  (e) Except as otherwise provided in Sections 2.5(d), the
         amount of each Revolving Loan may not be more than the then applicable
         Maximum Line A Loan Amount less the aggregate amount of all Revolving
         Loans previously made and outstanding. The amount of each Line B Loan
         may not be more than the then applicable Line B Commitment less the
         aggregate amount of all Line B Loans previously made and outstanding.

                  (f) After giving effect to any Loan, there may not be more
         than ten different Interest Periods in effect with the respect to IBOR
         Loans.

         2.4 Conversion and Continuation Elections. (a) Borrower may, upon
irrevocable written notice to Bank in accordance with subsection 2.4(b):

                  (i) elect, as of any Banking Day, in the case of Reference
         Rate Loans, or as of the last day of the applicable Interest Period, in
         the case of any other Type of Loan, to convert any such Loan (or any
         part thereof which is an integral multiple of $100,000 and which is not
         less than $500,000) into a Loan of another Type; or

                  (ii) elect, as of the last day of the applicable Interest
         Period, to continue any Loan having an Interest Period expiring on such
         day (or any part thereof which is

                                      -22-


<PAGE>   27
         in an integral multiple of $100,000 and which is not less than
         $500,000);

         provided, that if at any time the aggregate amount of any IBOR Loan is
         reduced, by payment, prepayment, or conversion of part thereof, to be
         less than $500,000, such IBOR Loan shall automatically convert into a
         Reference Rate Loan, and on and after such date the right of Borrower
         to continue such Loan as, and convert such Loan into, an IBOR Loan
         shall terminate.

                  (b) Borrower shall deliver a Request for Redesignation in
the form of the attached Exhibit D to be received by Bank not later than 9:00
a.m. (California time) at least (i) three Business Days in advance of the
Redesignation Date, if the Loan is to be converted into or continued as an IBOR
Loan bearing interest determined in relation to the IBOR Rate; and (ii) one
Business Day in advance of the Redesignation Date, if the Loan is to be
converted into a Reference Rate Loan, specifying:

                           A.       the proposed Redesignation Date;

                           B.       the aggregate amount of the Loan to be
         converted or continued;

                           C.       the Type of Loan resulting from the
         proposed conversion or continuation; and

                           D.       other than in the case of redesignation
         into a Reference Rate Loan, the duration of the requested
         Interest Period.

                  (c) If, upon the expiration of any Interest Period for an IBOR
Loan, Borrower has failed to select timely a new Interest Period for a
refinancing IBOR Loan, or if any Default or Event of Default then exists,
Borrower shall be deemed to have elected to convert such IBOR Loan into a
Reference Rate Loan effective as of the expiration date of such Interest Period.

                  (d) During the existence of a Default or Event of Default,
Borrower may not elect to have a Loan converted into or continued as an IBOR
Loan.

                  (e) After giving effect to any redesignation of a Loan, there
may not be more than ten different Interest Periods in effect with respect to
IBOR Loans.

         2.5  Standby Letters of Credit.

                  (a) Subject to the terms and conditions hereof, at any time
         and from time to time from the Restated Closing Date through the
         Banking Day immediately preceding the Revolver Termination Date, Bank
         shall issue such Standby Letters of Credit as Borrower may request by a
         Request for Standby Letter of Credit; provided that, upon giving effect
         to such Standby Letter of Credit, (i) Total Line A Outstandings shall
         not exceed the Line A Commitment, and (ii) Outstanding Standby Letters
         of Credit shall not exceed $1,000,000. Unless the Bank otherwise
         consents in writing, the term of any Standby Letter of Credit shall not
         exceed 18 months and shall in no event extend beyond the Revolver
         Termination Date. No Standby Letter of Credit shall be issued except to
         the extent reasonably necessary in the ordinary course of the business
         of Borrower or its Subsidiaries, and no Standby Letter of Credit shall
         be issued in any event to support any workers' compensation obligation
         of Borrower or its Subsidiaries. A Standby Letter of Credit may include
         a provision providing that the expiry date thereof will be
         automatically extended each year for an additional year unless Bank
         gives written notice to the contrary; provided, however, that each
         Standby Letter of Credit shall include a final expiry date which shall
         not be subject to automatic extension. Unless otherwise agreed to by
         Bank, the face amount of any Standby Letter of Credit shall not be less
         than $100,000.

                  (b) Each Request for Standby Letter of Credit shall be
         submitted to Bank not later than 11:00 a.m., Los Angeles time, at least
         ten (10) Banking Days prior to the date upon which the requested
         Standby Letter of Credit is to be issued.

                  (c) Borrower agrees to pay to Bank, at its office designated
         as its address for notices pursuant to this Agreement, or at such other
         payment location as Bank shall have specified in writing to Borrower,
         with respect to each Standby Letter of Credit, within one (1) Banking
         Day after demand therefor, a principal amount equal to any payment made
         by the Bank under that Standby Letter of Credit, together with interest
         on such amount from the date of any payment made by Bank through the
         date of payment by Borrower at the rate provided for in Section 3.6.
         The principal amount of any such payment made by Borrower to Bank shall
         be used to reimburse Bank for the payment made by it under the Standby
         Letter of Credit.

<PAGE>   29
                  (d) Each time Borrower fails to make any payment required by
         Section 2.5(c), Bank may, but is not required to, without notice to or
         the consent of Borrower, make a Revolving Loan under the Line A
         Commitment in an aggregate amount equal to the amount paid by Bank on
         the relevant Standby Letter of Credit, whether or not the same would
         cause Total Line A Outstandings to exceed the Line A Commitment
         (without waiving the obligation of Borrower to reduce Total Line A
         Outstandings to an amount less than or equal to the Line A Commitment),
         and, for this purpose, the conditions precedent set forth in Article 8
         and the amount limitations set forth in Section 2.3(a) shall not apply.
         The proceeds of such Revolving Loan shall be paid to Bank to reimburse
         it for the payment made by it under the Standby Letter of Credit.

                  (e) The issuance of any supplement, modification, amendment,
         renewal or extension to or of any Standby Letter of Credit shall be
         treated in all respects the same as the issuance of a new Standby
         Letter of Credit.

                  (f) The obligation of Borrower to pay to Bank the amount of
         any payment made by Bank under the Standby Letter of Credit shall be
         absolute, unconditional and irrevocable. Without limiting the
         foregoing, such obligation of Borrower shall not be affected by any of
         the following circumstances:

                (i) any lack of validity or enforceability of
the Standby Letter of Credit, this Agreement, or any
other agreement or instrument relating thereto;

                           (ii) any amendment or waiver of or any consent to
                  departure from the Standby Letter of Credit, this Agreement,
                  or any other agreement or instrument relating thereto;

                           (iii) the existence of any claim, setoff, defense or
                  other rights which Borrower may have at any time against Bank,
                  any beneficiary of the Standby Letter of Credit (or any
                  Persons or entities for whom any such beneficiary may be
                  acting) or any other Person, whether in connection with the
                  Standby Letter of Credit, this Agreement or any other
                  agreement or instrument relating thereto, or any unrelated
                  transactions;

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

                           (v) payment by Bank under the Standby Letter of
                  Credit against presentation of a draft or any accompanying
                  document which does not strictly comply with the terms of the
                  Standby Letter of Credit, but which contains some ministerial
                  discrepancy, the existence of which does not have a material
                  adverse effect on the business, operations or condition
                  (financial or otherwise) of Borrower and its Subsidiaries,
                  taken as a whole;

                           (vi) the solvency (or insolvency) or financial
                  responsibility (or lack thereof) of any party issuing any
                  documents in connection with the Standby Letter of Credit;

                           (vii) any error in the transmission of any message
                  relating to the Standby Letter of Credit not caused by Bank,
                  or any delay or interruption in any such message; and/or

                           (viii) any error, neglect or default of any
                  correspondent of Bank in connection with the Standby Letter of
                  Credit.

                  (g) On and after the Restated Closing Date, Standby Letter of
         Credit Number 216411, as amended, issued by Bank and with a face amount
         as of the Restated Closing Date in the amount of $341,512, shall be
         deemed for all purposes, including for purposes of the fees to be
         collected pursuant to Section 3.4, and reimbursement of costs and
         expenses to the extent provided herein, a Standby Letter 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.

                  (h) Upon (i) the request of Bank, (A) if Bank has honored any
         full or partial drawing request on any Standby Letter of Credit and
         such drawing has resulted in a Line A Loan hereunder, or (B) if, as of
         the Revolver Termination Date, any Standby Letter of Credit may for any
         reason remain outstanding and partially or wholly undrawn, or (ii) upon
         the occurrence of a Default or an Event of Default, then, Borrower
         shall immediately Cash Collateralize the Letter of Credit Obligations
         in an amount equal to such Letter of Credit Obligations.

                  (i) Borrower agrees to sign Bank's form Application and
         Agreement for Standby Letter of Credit upon demand by Bank.

<PAGE>   31
                  (j) Subject to the next sentence, a Standby Letter of Credit
         may be requested pursuant to this Section 2.5 for the account of
         Borrower or for the account of any Subsidiary of Borrower. To the
         extent that a Subsidiary of Borrower is the account party under any
         Standby Letter of Credit, Borrower hereby guarantees the payment and
         performance of such Subsidiary with respect to any Obligation of such
         Subsidiary relating to such Standby Letter of Credit, and agrees to
         deliver to Bank, duly executed and in form and content acceptable to
         Bank, a duly executed continuing guaranty further evidencing the
         foregoing guaranty, together with a resolution or other evidence of the
         corporate authority of Borrower to execute, perform and deliver such
         continuing guaranty.

         2.6 Voluntary Reduction of the Commitments. Borrower shall have the
right, at any time and from time to time, without penalty or charge, upon at
least two (2) Banking Days prior written notice to Bank, voluntarily to reduce,
permanently and irrevocably, in aggregate principal amounts of an integral
multiple of $50,000 (but not less than $250,000), or to terminate, the then
undisbursed portion of the Commitments, provided that any such reduction or
termination shall be accompanied by all accrued and unpaid commitment fees, if
any, with respect to the portion of the Commitments being reduced or terminated,
and provided further that the Line A Commitment shall not be reduced to an
amount less than the amount of Total Line A Outstandings and the Line B
Commitment shall not be reduced to an amount less than the amount of Total Line
B Outstandings.

         2.7  Automatic Reduction of the Line A Commitment.

                  (a) The Line A Commitment shall automatically and permanently
         reduce on each December 31 in the amount set forth below opposite the
         year in which such date occurs:

                  (b) In addition to the foregoing, on or before March 30 of
         each Fiscal Year (commencing March 30, 1997), the Line A Commitment
         shall automatically and permanently reduce by an amount equal to 75% of
         the Excess Cash Flow of Borrower and its Subsidiaries for the
         immediately prior Fiscal Year; provided, however, that at such time as
         the

                                      -27-


<PAGE>   32
         Line A Commitment is less than or equal to $14,000,000, no further
         reductions thereof shall be required pursuant to this Section 2.7(b).

                  (c) In addition to the foregoing, the Line A Commitment shall,
         concurrently with the receipt by the Borrower (or any Subsidiary) of
         the net cash proceeds from the issuance of equity securities, be
         reduced by the amount of such net cash proceeds. As used in the
         preceding sentence, "equity securities" shall not include (i) any
         security issued upon the conversion of the Borrower's Subordinated
         Obligations, or (ii) any security issued under the Borrower's employee
         stock plans to the extent that the net cash proceeds of the sale of
         such securities do not exceed $100,000 in the aggregate in any Fiscal
         Year.

                  (d) In addition to the foregoing, the Line A Commitment shall
         automatically reduce upon any Disposition by an amount equal to 80% of
         the Net Cash Proceeds received by the Borrower or its Subsidiaries upon
         such Disposition.

         2.8 Automatic Increase of the Line A Commitment. The Line A Commitment
shall automatically increase on the Line B Termination Date by an amount equal
to Total Line B Outstandings on such date, provided, however, in no event shall
the Line A Commitment exceed $24,000,000.

         2.9 Automatic Termination of the Line B Commitment. The Line B
Commitment will terminate on the Line B Termination Date.

                                PAYMENTS AND FEES

         3.1  Principal and Interest.

                  (a) Interest shall be payable on the outstanding daily unpaid
         principal amount of each Loan from the date thereof until payment in
         full is made and shall accrue and be payable at the rates set forth
         herein both before and after default and before and after maturity and
         judgment, with interest on overdue interest to bear interest at the
         rate set forth in Section 3.6, to the fullest extent permitted by
         applicable Law. Upon prepayment or payment in full of all outstanding
         Loans, interest accrued through the date of such prepayment or payment
         shall be payable on such date.

                  (b) Interest accrued on each Reference Rate Loan shall be
         payable monthly on or before the first Banking Day of each fiscal month
         of Borrower, commencing with the first such date to occur following the
         Restated Closing Date. Bank shall use its best efforts to notify
         Borrower of the amount of interest so payable prior to each interest
         payment date, but failure of Bank to do so shall not excuse payment of
         such interest when payable. Except as otherwise provided in Section
         3.6, the unpaid principal amount of any Reference Rate Loan shall bear
         interest at a fluctuating rate per annum equal to the Reference Rate
         plus the applicable Reference Rate Spread. Each change in the interest
         rate shall take effect simultaneously with the corresponding change in
         the Reference Rate and/or the Reference Rate Spread. Each change in the
         Reference Rate shall be effective as of 12:01 a.m. on the Banking Day
         on which the change in the Reference Rate is announced, unless
         otherwise specified in such announcement, in which case the change
         shall be effective as so specified.

                  (c) Interest accrued on each IBOR Loan which is for a term of
         three months or less shall be due and payable on the last day of the
         related Interest Period. Interest accrued on each other IBOR Rate Loan
         shall be due and payable on the date which is three months after the
         date such IBOR Loan was made and on the last day of the related
         Interest Period. Except as otherwise provided in Section 3.6, the
         unpaid principal amount of any IBOR Loan shall bear interest at a rate
         per annum equal to the IBOR Rate for that IBOR Loan plus the applicable
         IBOR Rate Spread.

                  (d)      If not sooner paid, the principal indebtedness
         evidenced by the Notes shall be payable as follows:

                                      -29-


<PAGE>   34
                  (i) the amount, if any, by which the principal indebtedness
         evidenced by the Revolving Line Note at any time exceeds the Maximum
         Line A Loan Amount shall be payable immediately.

                  (ii) the principal indebtedness evidenced by the Revolving
         Line Note shall be payable on the Revolver Termination Date.

                  (iii) the principal indebtedness evidenced by the Line B Note
         shall be payable on the Line B Termination Date. Bank acknowledges that
         Borrower may use the proceeds of Revolving Loans (if available) to
         repay the outstanding Line B Loans on such date.

                  (iv) the amount, if any, by which the principal indebtedness
         evidenced by the Line B Note at any time exceeds the Line B Commitment
         shall be payable immediately.

         (e) The Notes, or either of them, may, at any time and from time to
time, be voluntarily paid or prepaid in whole or in part without premium or
penalty; provided that: (i) any partial prepayment shall be in an amount not
less than $500,000 in the case of an IBOR Loan, (ii) Bank shall have received
notice of any prepayment at least three Banking Days before the date of
prepayment, in the case of an IBOR Loan, and at least one Banking Day before the
date of a prepayment, in the case of a Reference Rate Loan, (iii) each
prepayment of principal shall be accompanied by payment of interest accrued
through the date of payment on the amount of principal paid, and (iv) in the
case of any prepayment of any IBOR Loan, Borrower shall promptly upon demand
reimburse Bank for any loss or cost directly or indirectly resulting from the
prepayment, determined as set forth in Section 3.5.

         3.2  Facility Fee.

         (a) Borrower shall pay to Bank a one time nonrefundable Line B
facility fee in an aggregate amount equal to $25,000 with respect to the Line B
Commitment. Bank acknowledges that it has received such fee.

         (b) On or before he Restated Closing Date, Borrower shall pay to Bank a
nonrefundable Line A facility fee in an amount equal to .25% of the Line A
Commitment, less $18,714. Thereafter, on each July 1, commencing July 1, 1997,
Borrower shall pay to Bank an annual Line A facility fee in an amount equal to
0.25% of the Line A Commitment on such date. Such facility fee shall be fully
earned as

                                      -30-


<PAGE>   35
         of the date when due and shall be non-refundable under any
         circumstances. Such facility fee shall be due and payable on or before
         the Restated Closing Date.

         3.3  Commitment Fee and Special Commitment Costs.

                  (a) For the period from the Restated Closing Date through the
         Revolver Termination Date, Borrower shall pay to Bank a commitment fee
         equal to .25% per annum times the average daily difference between the
         Line A Commitment and the Total Line A Outstandings. Such commitment
         fee shall be payable quarterly in arrears within 5 Banking Days after
         the end of each calendar quarter, commencing with the quarter ending
         June 30, 1996. Bank shall use its best efforts to notify Borrower of
         the amount of the commitment fee so payable prior to each fee payment
         date, but failure of Bank to do so shall not excuse payment of such fee
         when payable.

                  (b) On the Line B Termination Date, Borrower shall pay to Bank
         a commitment fee equal to .50% per annum times the average Total Line B
         Outstandings from the Restated Closing Date through the Line B
         Termination Date.

                  (c) If Bank determines that compliance with any Law or
         regulation or with any guideline or request from any central bank or
         other Governmental Agency (whether or not having the force of Law)
         relating to the capital adequacy of banks or corporations in control of
         banks has or would have the effect of reducing the rate of return on
         the capital of Bank or any corporation controlling Bank as a
         consequence of, or with reference to, Bank's Commitments hereunder
         below the rate which Bank or such other corporation could have achieved
         but for such compliance (taking into account the policies of Bank or
         corporation with regard to capital adequacy), then Borrower shall from
         time to time, upon demand by Bank in accordance with this Section 3.3,
         within 15 days after demand, pay to Bank additional amounts sufficient
         to compensate Bank or such other corporation for such reduction.

                           (i) Bank may not seek compensation under this Section
                  3.3(c) for any reduction in rate of return in respect of any
                  period which is more than eighteen months prior to the Bank's
                  demand for such compensation.

                           (ii) A certificate as to any amounts for which Bank
                  is seeking compensation under Section 3.3.(c), submitted to
                  Borrower by Bank, shall be conclusive and binding for all
                  purposes, absent manifest error. Bank shall calculate such
                  amounts in a manner which

                                      -31-


<PAGE>   36
                  is consistent with the manner in which it makes calculations
                  for comparable claims with respect to similarly situated
                  borrowers from Bank and will not allocate to Borrower a
                  proportionately greater amount of such compensation than it
                  allocates to each of its other commitments to lend or other
                  loans with respect to which it is entitled to demand
                  comparable compensation. Bank agrees promptly to notify
                  Borrower of any circumstances that would cause Borrower to pay
                  additional amounts pursuant to this Section 3.3.(c), provided
                  that the failure to give such notice shall not affect
                  Borrower's obligation to pay such additional amounts
                  hereunder.

         3.4 Standby Letter of Credit Fees and Costs. Borrower shall pay a
letter of credit fee equal to the greater of $500 or 2.00% per annum of the
outstanding undrawn amount of each Standby Letter of Credit issued under Section
2.5, payable at the time of issuance. Each Standby Letter of Credit fee is
earned upon issuance of each Standby Letter of Credit and is nonrefundable. In
addition, Borrower shall pay to Bank upon demand issuance and/or other fees the
Bank notifies Borrower will be charged for issuing and processing Borrower's
Letters of Credit.

         3.5  IBOR Fees and Costs.

                  (a)      If the occurrence of any Regulatory Development
         after the Restated Closing Date:

                           (1) shall subject Bank or its IBOR Lending Office to
                  any tax, duty or other charge or cost with respect to any IBOR
                  Loan or its obligation to make IBOR Loans, or shall change the
                  basis of taxation of payments to Bank of the principal of or
                  interest on any IBOR Loan or any other amounts due under this
                  Agreement in respect of any IBOR Loan or its obligation to
                  make IBOR Loans (except for changes in any tax on the overall
                  net income, gross income or gross receipts of Bank or its IBOR
                  Lending Office);

                           (2) shall impose, modify or deem applicable any
                  reserve (including, without limitation, any reserve imposed by
                  the Board of Governors of the Federal Reserve System), special
                  deposit or similar requirements (excluding any such
                  requirement included in any applicable Reserve Percentage)
                  against assets of, deposits with or for the account of, or
                  credit extended by, Bank or its IBOR Lending Office; or

                           (3) shall impose on Bank or its IBOR Lending Office
                  or the IBOR Market any other condition

                                      -32-


<PAGE>   37
                  affecting any IBOR Loan or its obligation to make
                  IBOR Loans, or shall otherwise affect any of the
                  same;

         and the result of any of the foregoing, as determined by Bank,
         increases the cost to Bank or its IBOR Lending Office of making or
         maintaining any IBOR Loan or in respect of any IBOR Loan or its
         obligation to make IBOR Loans or reduces the amount of any sum received
         or receivable by Bank or its IBOR Lending Office with respect to any
         IBOR Loan or its obligation to make IBOR Loans (assuming Bank's IBOR
         Lending Office had funded 100% of its IBOR Loan in the IBOR Market),
         then, within 15 days after demand by Bank, Borrower shall pay to Bank
         such additional amount or amounts as will compensate Bank for such
         increased cost or reduction (determined as though Bank's IBOR Lending
         Office had funded 100% of its IBOR Loan in the IBOR Market); provided
         that Borrower shall not be liable to Bank for any such increased cost
         or reduction pursuant to this Section in respect of any period which is
         more than eighteen months prior to Bank's demand for such compensation.
         A statement of Bank claiming compensation under this subsection and
         setting forth the additional amount or amounts to be paid to it
         hereunder shall be conclusive in the absence of manifest error. Bank
         agrees to endeavor promptly to notify Borrower of any event of which it
         has actual knowledge which will entitle Bank to compensation pursuant
         to this Section, and agrees to designate a different IBOR Lending
         Office if such designation will avoid the need for or reduce the amount
         of such compensation and will not, in the judgment of Bank, otherwise
         be disadvantageous to Bank. If Bank claims compensation under this
         Section, Borrower may at any time, upon at least four (4) IBOR Market
         Days' prior notice to Bank and upon payment in full of the amounts
         provided for in this Section through the date of such payment plus any
         prepayment fee required by Section 3.8(d), pay in full the affected
         IBOR Loans of such Bank or request that such IBOR Loans be converted to
         Reference Rate Loans.

                  (b) If after the Restated Closing Date the occurrence of any
         Regulatory Development shall, in the opinion of Bank, make it unlawful
         or impossible for Bank or its IBOR Lending Office to make, maintain or
         fund its portion of any IBOR Loan, or to take deposits of dollars in
         the IBOR Market, or to determine or charge interest rates based upon
         the IBOR, then Bank's obligation to make IBOR Loans shall be suspended
         for the duration of such illegality or impossibility and Bank shall
         give notice thereof to Borrower. Before giving any notice pursuant to
         this Section, Bank shall designate a different Lending Office if such
         designation will avoid the need for giving

                                      -33-


<PAGE>   38
         such notice and will not, in the judgment of Bank, be otherwise
         disadvantageous to Bank. Upon receipt of such notice, the outstanding
         principal amount of Bank's IBOR Loans, together with accrued interest
         thereon, automatically shall be converted to Reference Rate Loans on
         either (1) the last day of the Interest Period(s) applicable to such
         IBOR Loans if Bank may lawfully continue to maintain and fund such IBOR
         Loans to such day(s) or (2) immediately if Bank may not lawfully
         continue to fund and maintain such IBOR Loans to such day(s), provided
         that in such event the conversion shall not be subject to payment of a
         prepayment fee under Section 3.8(d). In the event that Bank is unable,
         for the reasons set forth above, to make, maintain or fund its portion
         of any IBOR Loan, Bank shall fund such amount as a Reference Rate Loan
         for the same period of time, and such amount shall be treated in all
         respects as a Reference Rate Loan.

                  (c) If, with respect to any proposed IBOR Loan, the Bank
         reasonably determines that, by reason of circumstances affecting the
         IBOR Market generally that are beyond the reasonable control of Bank,
         deposits in dollars (in the applicable amounts) are not being offered
         to Bank in the IBOR Market for the applicable Interest Period, then
         Bank shall give notice thereof to Borrower, whereupon until Bank
         notifies Borrower that the circumstances giving rise to such suspension
         no longer exist, the obligation of Bank to make any future IBOR Loan
         shall be suspended. If at the time of such notice there is then pending
         a Request for Loan that specifies an IBOR Loan, such Request for Loan
         shall be deemed to specify a Reference Rate Loan.

                  (d) Upon payment or prepayment of any IBOR Loan (other than as
         the result of a conversion required under Section 3.8(b)) on a day
         other than the last day in the applicable Interest Period (whether
         voluntarily, involuntarily, by reason of acceleration, or otherwise),
         or upon the failure of Borrower to borrow on the date or in the amount
         specified for a IBOR Loan in any Request for Loan, Borrower shall pay
         to Bank any cost or expense incurred by Bank as a result of such
         payment or prepayment, together with a prepayment fee in an amount
         equal to the amount, if any, by which (x) the additional interest that
         would have accrued (without any applicable IBOR Spread) on the
         principal amount prepaid on account of the IBOR Loan had it remained
         outstanding until the last day of the applicable Interest Period,
         exceeds (y) the interest that Bank could recover by placing funds in
         the amount of the prepayment on deposit in the IBOR Market selected by
         Bank for a period beginning on the date of the prepayment and ending on
         the last day of the applicable Interest Period, or for a comparable
         period for which an appropriate rate

                                      -34-


<PAGE>   39
         quote may be obtained. Bank's determination of the amount of any
         prepayment fee or failure to borrow fee payable under this Section
         3.5(d) shall be conclusive in the absence of manifest error.

                  (e) Any statement or certificate given by Bank under this
         Section 3.5(e) shall satisfy the requirements set forth in Section
         3.3(c) with respect to requests for reimbursement under Section 3.3(a)

         3.6 Default Rate/Late Payments. Upon the occurrence and during the
continuation of any default under this Agreement, Loans under this Agreement
shall, at the option of Bank, bear interest at a rate per annum which is 2.5
percentage points higher than the highest rate of interest otherwise provided
under this Agreement. This will not constitute a waiver of any Default. In
addition, should any installment of principal or interest or any fee or cost or
other amount payable under any Loan Document to Bank not be paid when due, it
shall thereafter bear interest at a fluctuating interest rate per annum at all
times equal to the highest rate of interest otherwise provided under this
Agreement plus the Reference Rate Spread plus 2.00% per annum, to the fullest
extent permitted by applicable Law. This will not constitute a waiver of any
default. Accrued and unpaid interest on past due amounts (including, without
limitation, interest on past due interest) shall be compounded monthly, on the
last day of each calendar month, to the fullest extent permitted by applicable
Law.

         3.7 Computation of Interest and Fees. All computations of interest and
fees under any Loan Document shall be calculated on the basis of a year of 360
days and the actual number of days elapsed, which results in more interest and
fees than if a 365-day year were used.

         3.8 Non-Banking Days. If any payment to be made by Borrower or any
other Party under any Loan Document shall come due on a day other than a Banking
Day, payment shall be made on the next succeeding Banking Day and the extension
of time shall be reflected in computing interest.

         3.9  Manner and Treatment of Payments.

                  (a) Each payment hereunder or on the Notes or under any other
         Loan Document shall be made to Bank, at Bank's Office, in immediately
         available funds not later than 12:00 noon, Los Angeles time, on the day
         of payment (which must be a Banking Day). All payments received after
         12:00 noon, Los Angeles time, on any Banking Day, shall be deemed
         received on the next succeeding Banking Day. All payments shall be made
         in lawful money of the United States of America.

                                      -35-


<PAGE>   40
                  (b) Bank shall use its best efforts to keep a record of Loans
         made by it and payments received by it with respect to the Notes and
         such record shall be presumptive evidence of the amounts owing.
         Notwithstanding the foregoing sentence, Bank shall not be liable to any
         Party for any failure to keep such a record.

                  (c) Each payment of any amount payable by Borrower and/or any
         other Party under this Agreement and/or any other Loan Document shall
         be made free and clear of, and without reduction by reason of, any
         taxes, assessments or other charges imposed by any Governmental Agency,
         central bank or comparable authority.

         3.10 Funding Sources. Nothing in this Agreement shall be deemed to
obligate Bank to obtain the funds for any Loan in any particular place or manner
or to constitute a representation by Bank that it has obtained or will obtain
the funds for any Loan in any particular place or manner.

         3.11 Failure to Charge Not Subsequent Waiver. Any decision by Bank not
to require payment of any interest (including default interest), fee, cost or
other amount payable under any Loan Document on any occasion shall in no way
limit or be deemed a waiver of Bank's right to require full payment of any
interest (including default interest), fee, cost or other amount payable under
any Loan Document on any other or subsequent occasion.

         3.12 Survivability. All of Borrower's obligations under this Article 3
shall survive for one year following the date on which all Loans hereunder were
fully paid.

         3.13  Direct Debit (Pre-Billing).

                  (a) Borrower agrees that Bank will debit Borrower's Designated
         Deposit Account on the date each payment of principal and interest and
         any fees from Borrower becomes due (the "Due Date"). If the Due Date is
         not a Banking Day, the Designated Deposit Account will be debited on
         the next Banking Day.

                  (b) Approximately 10 days prior to each Due Date, Bank will
         mail to Borrower a statement of the amounts that will be due on that
         Due Date (the "Billed Amount"). The calculation will be made on the
         assumption that no new extensions of credit or payments will be made
         between the date of the billing statement and the Due Date, and that
         there will be no changes in the applicable interest rate.

                  (c) Bank will debit the Designated Deposit Account for the
         Billed Amount, regardless of the actual amount due on that date (the
         "Accrued Amount"). If the Billed Amount debited to the Designated
         Deposit Account differs from the Accrued Amount, the discrepancy will
         be treated as follows:

                          (i)        If the Billed Amount is less than the
                  Accrued Amount, the Billed Amount for the following Due Date
                  will be increased by the amount of the discrepancy. Borrower
                  will not be in default by reason of any such discrepancy.

                         (ii)        If the Billed Amount is more than the
                  Accrued Amount, the Billed Amount for the following Due Date
                  will be decreased by the amount of the discrepancy.

         Regardless of any such discrepancy, interest will continue to accrue
         based on the actual amount of principal outstanding without
         compounding. Bank will not pay Borrower interest on any overpayment.

                  (d) Borrower will maintain sufficient funds in the Designated
         Deposit Account to cover each debit. If there are insufficient funds in
         the Designated Deposit Account on the date Bank enters any debit
         authorized by this Agreement, the debit will be reversed.

                         REPRESENTATIONS AND WARRANTIES

                  Borrower represents and warrants to Bank, as of the Restated

California. Borrower is duly qualified or registered to transact business and is
in good standing in California and each other jurisdiction in which the conduct
of its business or the ownership or leasing of its Properties makes such

on the business, operations or condition (financial or otherwise) of Borrower
and its Subsidiaries, taken as a whole. Borrower has all requisite power and
authority to conduct its business, to own and lease its Properties and to
execute, deliver and perform all of its Obligations under the Loan Documents.
All outstanding shares of capital stock of Borrower are duly authorized, validly
issued, fully paid, non-assessable and issued in compliance with all applicable
state and federal securities and other Laws. Borrower is in compliance with all
Laws and other legal requirements applicable to its business, has obtained all
authorizations, consents, approvals, orders, licenses and permits from, and has
accomplished all filings, registrations and qualifications with, or obtained
exemptions from any of the foregoing from, any Governmental Agency that are

adverse effect on the business, operations or condition (financial or otherwise)
of Borrower and its Subsidiaries, taken as a whole.

         4.2 Authority; Compliance With Other Agreements and Instruments and
Government Regulations. The execution, delivery and performance by each of
Borrower and its Subsidiaries of the Loan Documents to which it is a Party have
been duly authorized by all necessary action, and do not and will not:

         or amendments thereto, as applicable;

                  (c) Result in or require the creation or imposition of any
         Lien or Right of Others (other than as provided under the Loan
         Documents) upon or with respect to any Property now owned or leased or
         hereafter acquired by such Party;

                  (d) Violate any provision of any Law (including, without
         limitation, Regulations G, T, U and/or X of the Board of Governors of
         the Federal Reserve System), order, writ, judgment, injunction, decree,
         determination or award presently in effect and having applicability to
         such Party; or

                  (e) Result in a breach of or constitute a default under, or
         cause or permit the acceleration of any obligation owed under, any
         indenture or loan or credit agreement or any other material agreement,
         lease or instrument to which such Party is a party or by which such
         Party or any of its Property is bound or affected;

and neither Borrower nor any Subsidiary thereof is in default under any Law,
order, writ, judgment, injunction, decree, determination or award, or any
indenture, agreement, lease or instrument described in Section 4.2(e), in any
respect that is materially adverse to the interests of Bank or that would have
any material adverse effect on the business, operations or condition (financial
or otherwise) of Borrower and its Subsidiaries, taken as a whole.

         4.3 No Governmental Approvals Required. No authorization, consent,
approval, order, license or permit from, or filing, registration or
qualification with, or exemption from any of the foregoing from, any
Governmental Agency is or will be required to authorize or permit under
applicable Law the execution, delivery and performance by Borrower or any
Subsidiary thereof of the Loan Documents to which it is a Party.

         of legal entity and jurisdictions of formation of all Subsidiaries of
         Borrower. Except as described in Schedule 4.4, Borrower does not own
         any capital stock, partnership interest, joint venture interest or
         other equity interest in any Person. Unless otherwise indicated in
         Schedule 4.4, all of the outstanding shares of capital stock or
         partnership or joint venture interests of each Subsidiary of Borrower
         are owned of record and benefici-

         ally by Borrower, and all securities and interests so owned are duly
         authorized, validly issued, fully paid, non-assessable and issued in
         compliance with all applicable state and federal securities and other
         Laws, and are free and clear of all Liens and Rights of Others.

                  (b) Each Subsidiary of Borrower is a legal entity of the form
         described for that Subsidiary in Schedule 4.4, duly formed, validly
         existing and in good standing under the Laws of its jurisdiction of
         formation, is duly qualified or registered to transact business and is
         in good standing in each other jurisdiction in which the conduct of its
         business or the ownership or leasing of its Properties makes such
         qualification or registration necessary, except where the failure so to
         qualify or register and to be in good standing would not have a
         material adverse effect on the business, operations or condition
         (financial or otherwise) of Borrower and its Subsidiaries, taken as a
         whole, and has all requisite legal power and authority to conduct its
         business and to own and lease its Properties and to execute, deliver
         and perform all of its Obligations under the Loan Documents.

                  (c) Each Subsidiary of Borrower is in compliance with all Laws
         (subject to the matters referred to in Schedule 4.20) and other legal
         requirements applicable to its business, has obtained all
         authorizations, consents, approvals, orders, licenses and permits from,
         and has accomplished all filings, registrations and qualifications
         with, or obtained exemptions from any of the foregoing from, any
         Governmental Agency that are necessary for the transaction of its
         business, except where the failure so to comply, file, register,
         qualify or obtain exemptions would not have a material adverse effect
         on the business, operations or condition (financial or otherwise) of
         Borrower and its Subsidiaries, taken as a whole.

         4.5 Financial Statements. Borrower has furnished to Bank (a) the
audited consolidated balance sheet of Borrower and its Subsidiaries as at
December 31, 1995, and audited consolidated statements of profit and loss and of
changes in financial position of Borrower and its Subsidiaries for their fiscal
year then ended, and (b) the unaudited consolidated and consolidating balance
sheets of Borrower and its Subsidiaries as at March 31, 1996, and unaudited
consolidated and consolidating statements of profit and loss and of changes in
financial position of Borrower and its Subsidiaries for such quarter and for the
portion of their fiscal year ended with such quarter. Such financial statements
fairly present in all material respects the financial condition, results of
operations and changes in financial position of Borrower and its Subsidiaries as
at such dates and for such periods, in conformity with

                                      -40-


<PAGE>   45
generally accepted accounting principles, consistently applied, provided that
the balance sheets and statements referred to in (b) above are subject to normal
year-end audit adjustments.

         4.6 No Other Liabilities; No Material Adverse Changes. Borrower and its
Subsidiaries do not have any material liability or material contingent liability
not reflected or disclosed in the financial statements or notes thereto
described in Section 4.5. There has been no material adverse change in the
business, operations or condition (financial or otherwise) of Borrower and its
Subsidiaries, taken as a whole, since the date of the financial statements
described in Section 4.5(b).

         4.7 Title to and Location of Property. Borrower and its Subsidiaries
have good and valid title to all the Property reflected in the financial
statements described in Section 4.5, other than Property subsequently sold in
the ordinary course of business, free and clear of all Liens and Rights of
Others other than Liens or Rights of Others permitted pursuant to Section 6.6.
Schedule 4.7 hereto sets forth the street address for all material interest in
real Property owned or held by Borrower or any of its Subsidiaries. All tangible
personal Property owned or held by Borrower or any of its Subsidiaries is
located within the States of California and Texas and the Country of Australia.

         4.8 Intangible Assets. Borrower and its Subsidiaries own, or possess
the unrestricted right to use, all trademarks, trade names, copyrights, patents,
patent rights, licenses and other Intangible Assets that are used in the conduct
of their businesses as now operated, and no such Intangible Asset, to the best
knowledge of Borrower, conflicts with the valid trademark, trade name,
copyright, patent, patent right or Intangible Asset of any other Person to the
extent that such conflict would have a material adverse effect on the business,
operations or condition (financial or otherwise) of Borrower and its
Subsidiaries, taken as a whole. Schedule 4.8 contains a complete and accurate
description of all pending and existing trademarks, tradenames, patents and
patent rights.

         4.9 Filing of Financing Statements. Except for the requirement that
continuation statements periodically be filed and/or recorded with respect to
financing statements describing the Collateral previously filed with the
California Secretary of State, all necessary steps will have been taken to fully
perfect and to maintain fully perfected the Liens of Bank on the Collateral, to
the fullest extent that such Liens may be perfected by the filing and/or
recording of financing statements pursuant to Division 9 of the California
Uniform Commercial Code.

         4.10 Public Utility Holding Company Act. Neither Borrower nor any
Subsidiary thereof is a "holding company", or a "subsidiary company" of a
"holding company", or an "affiliate" of a "holding company" or of a "subsidiary
company" of a "holding company", within the meaning of the Public Utility
Holding Company Act of 1935, as amended.

         4.11 Litigation. Except for (i) any matter fully covered (subject to
usual deductibles and retentions) by insurance for which the insurance carrier
has assumed full responsibility, (ii) any matter, or series of related or
similar matters, involving a claim against Borrower or any of its Subsidiaries
of less than $500,000, and (iii) matters set forth in Schedule 4.11 and in the
financial statements (or the notes thereto) described in Section 4.5, there are
no actions, suits or proceedings pending or, to the best knowledge of Borrower,
threatened against or affecting Borrower or any of its Subsidiaries or any
Property of any of them in any court of Law or before any Governmental Agency
that would impair Borrower's or any Subsidiary's financial condition or ability
to repay the Loans.

         4.12 Binding Obligations. Each of the Loan Documents to which Borrower
or any Subsidiary thereof is a Party will, when executed and delivered by such
Party, constitute the legal, valid and binding obligation of such Party,
enforceable against such Party in accordance with its terms, except as
enforcement may be limited by bankruptcy, insolvency, reorganization,
arrangement, moratorium or other similar Laws relating to or affecting
creditors' rights generally or equitable principles relating to the granting of
specific performance and other equitable remedies as a matter of judicial
discretion.

         4.13  No Default.  No event has occurred and is continuing
that is a Default.

         4.14  ERISA Plans.

                  (a) Borrower and each of its Subsidiaries has fulfilled its
         obligations, if any, under the minimum funding standards of ERISA and
         the Code with respect to each Plan and is in compliance in all material
         respects with the presently applicable provisions of ERISA and the
         Code, and has not incurred any liability with respect to any Plan under
         Title IV of ERISA.

         ERISA for which the PBGC requires 30 days notice.

                  (c) No action by Borrower or any Subsidiary to terminate or
         withdraw from any Plan has been taken and no

                                      -42-
<PAGE>   47
         notice of intent to terminate a Plan has been filed under Section 4041
         of ERISA.

                  (d) No proceeding has been commenced with respect to a Plan
         under Section 4042 of ERISA, and no event has occurred or condition
         exists which might constitute grounds for the commencement of such a
         proceeding.

         4.15 Regulations G, T, U and X; Investment Company Act. Neither
Borrower nor any of its Subsidiaries is engaged principally, or as one of its
important activities, in the business of extending credit for the purpose of
"purchasing" or "carrying" any "margin stock" or "margin security" within the
meanings of Regulations G, T, U or X, respectively, of the Board of Governors of
the Federal Reserve System. If requested by Bank, Borrower will furnish or will
cause its Subsidiaries, as requested, to furnish Bank with a statement or
statements in conformity with the requirements of Federal Reserve Forms G-3
and/or U-1 referred to in Regulations G or U of said Board of Governors. No part
of the proceeds of any Loan hereunder will be used to purchase or carry any such
"margin security" or "margin stock" or to extend credit to others for the
purpose of purchasing or carrying any such "margin security" or "margin stock"
in violation of Regulations G, T, U or X of said Board of Governors. Neither
Borrower nor any of its Subsidiaries is or is required to be registered under
the Investment Company Act of 1940.

         4.16 Disclosure. No written statement made by Borrower or any
Subsidiary thereof to Bank in connection with this Agreement, or in connection
with any Loan, or in connection with the issuance of any Standby Letter of
Credit, contains any untrue statement of a material fact or omits a material
fact necessary to make the statement made not misleading. To the best knowledge
of Borrower, there is no fact which Borrower has not disclosed to Bank in
writing which materially and adversely affects nor, so far as Borrower can now
foresee, is reasonably likely to prove to affect materially and adversely the
business, operations, Properties, prospects, profits or condition (financial or
otherwise) of Borrower and its Subsidiaries, taken as a whole, or the ability of
Borrower and its Subsidiaries to perform their Obligations under the Loan
Documents.

         4.17 Tax Liability. Borrower and its Subsidiaries have filed all income
tax returns which are required (including any extensions obtained pursuant to
applicable Law) to be filed, and have paid, or made provision for the payment
of, all taxes with respect to the periods, Property or transactions covered by
said returns, or pursuant to any assessment received by Borrower or any
Subsidiary thereof, except (a) such taxes, if any, as are being contested in
good faith by appropriate proceedings and as to which adequate reserves have
been




                                      -43-
<PAGE>   48
established and maintained and (b) miscellaneous taxes not willfully unpaid in
an aggregate amount not greater than $200,000.

         4.18 Fiscal Year. Borrower and its Subsidiaries each operate on a
fiscal year ("Fiscal Year") ending on December 31, with four fiscal quarters of
thirteen weeks ending on or about March 31, June 30, September 30 and December
31.

         4.19 Employee Matters. There is no strike, work stoppage or labor
dispute with any union or group of employees pending or overtly threatened
involving Borrower or any of its Subsidiaries.

         4.20 Environmental Matters. Except as disclosed on Schedule 4.20 and in
the financial statements (or the notes thereto) described in Section 4.5, (i)
the real Property of Borrower and the operations conducted thereon do not
violate any applicable Law, statute, ordinance, rule, regulation, order or
determination of any governmental authority or any restrictive covenant or deed
restriction (recorded or otherwise), including without limitation all applicable
zoning ordinances and building codes, flood disaster Laws and Environmental Laws
and regulations, in any respect which could have a material adverse effect on
the business, operations or condition (financial or otherwise) of Borrower; (ii)
without limitation of clause (i) above, Borrower's real Property and the
operations conducted by Borrower or any current or prior owner or operator of
such real Property or operation, are not in violation of or subject to any
existing, pending or threatened action, suit, investigation, inquiry or
proceeding by any governmental authority or to any remedial obligations under
any Environmental Laws which, if determined adversely to Borrower, could have a
material adverse effect on the business, operations or condition (financial or
otherwise) of Borrower; (iii) all notices, permits, licenses or similar
authorizations, if any, required to be obtained or filed in connection with the
operation or use of the real Property of Borrower, including without limitation
past or present treatment, storage, disposal or release of a hazardous substance
or solid waste into the environment, have been duly obtained or filed, except
where the failure to obtain or file same would not have a material adverse
effect on the business, operations or condition (financial or otherwise) of
Borrower; (iv) all significant amounts of hazardous waste generated at the real
Property of Borrower have in the past been and shall continue to be transported,
treated and disposed of only by carriers maintaining valid permits under RCRA
and any other Environmental Laws and only at treatment, storage and disposal
facilities maintaining valid permits under RCRA and any other Environmental Law,
which carriers and facilities have been and are, to the best of Borrower's
knowledge, operating in



                                      -44-
<PAGE>   49
compliance with such permits or are exempt from obtaining such permits; (v)
Borrower has no actual or constructive knowledge of the disposal or other
release of any hazardous substance or solid waste, or the threatened release of
hazardous substances, on or to the real Property of Borrower except in
compliance with Environmental Laws, and that it has not been notified of same by
any Governmental Agency; (vi) Borrower has no material contingent liability in
connection with any release or threatened release of any hazardous substance or
solid waste into the environment; and (vii) the use which Borrower makes or
intends to make of Borrower's real Property will not result in the unlawful or
unauthorized disposal or other release of any hazardous substance or solid waste
on or to the real Property of Borrower. The terms "hazardous substance,"
"release" and "threatened release" have the meanings specified in CERCLA, and
the terms "solid waste" and "disposal" (or "disposed") have the meanings
specified in RCRA; provided, however, in the event either CERCLA or RCRA is
amended so as to broaden the meaning of any term defined thereby, such broader
meaning shall apply subsequent to the effective date of such amendment, and
provided further that, to the extent the laws of any state in which any of the
real Property of Borrower is located establish a meaning for "hazardous
substance," "release," "solid waste" or "disposal" which is broader than that
specified in either CERCLA or RCRA, such broader meaning shall apply with regard
to the real Property of Borrower located in such state.

         4.21 Intercompany Indebtedness. All intercompany indebtedness between
Borrower and any of its divisions or Subsidiaries, or between any such division
or Subsidiary and any other division or Subsidiary, is evidenced only as a book
entry in the financial records of the parties thereto. There exists no
instrument or other transferable document evidencing such intercompany debt.

         4.22 Promissory Notes. Except as set forth on Schedule 4.22, neither
Borrower nor its Subsidiaries own or hold any promissory note or other debt
instrument with a book value in excess of $50,000.

         4.23 Projections. The pro forma financial statements delivered to Bank
in accordance with Section 7.1(g) represent Borrower's best estimate, as of the
date of each such statement, of the future financial performance of Borrower and
its Subsidiaries for the periods set forth therein. Such pro forma financial
statements are based on facts, as of the date of each such statement, known to
Borrower and on assumptions that, as of the date of each such statement, are
reasonable and consistent with such facts. No material (in amount and
likelihood) fact or assumption is omitted as a basis for such pro forma
financial statements which, in Borrower's reasonable business



                                      -45-
<PAGE>   50
judgment, should be included, and such pro forma financial statements are
reasonably based on such facts and assumptions.

         4.24 Teledyne Acquisition. In connection with, or as a result of, the
transaction contemplated by the Teledyne Acquisition Agreement, neither Borrower
nor any of its Subsidiaries will (i) assume liabilities, including Contingent
Obligations, except for those liabilities with (A) a contractual amount of less
than $100,000 in the aggregate if the purchase price to be paid in connection
therewith will not be decreased by an amount equal to the assumed liabilities,
or (B) a contractual amount of less than $1,000,000 in the aggregate if the
purchase price to be paid in connection therewith will be decreased by an amount
equal to the assumed liabilities; (ii) incur losses over the twelve month period
following the consummation of such transaction; or (iii) cause a Default or
Event of Default to occur. In addition, (1) the Teledyne Acquisition Price will
not exceed $4,000,000, and (2) the sum of the Teledyne Acquisition Price plus
the payments made by Borrower after January 1, 1996 to purchase or redeem its
Subordinated Obligations will not exceed $12,000,000.

                              AFFIRMATIVE COVENANTS
                           (OTHER THAN INFORMATION AND
                             REPORTING REQUIREMENTS)

         So long as any Loan remains unpaid, or any other Obligation remains
unpaid or unperformed, or any portion of the Commitments remains outstanding,
Borrower shall, and shall cause each of its Subsidiaries to, unless Bank
otherwise consents in writing:

         5.1 Payment of Taxes and Other Potential Liens. Pay and discharge
promptly all taxes, assessments and governmental charges or levies imposed upon
any of them, upon their respective Property or any part thereof, upon their
respective income or profits or any part thereof or upon any right or interest
of Bank under any Loan Document, except that Borrower and its Subsidiaries shall
not be required to pay or cause to be paid (a) any income or gross receipts tax
generally applicable to banks or (b) any tax, assessment, charge or levy that is
not yet past due, or is being contested in good faith by appropriate
proceedings, so long as the relevant entity has established and maintains
adequate reserves for the payment of the same and by reason of such nonpayment
and contest no material item or portion of Property of Borrower and its
Subsidiaries, taken as a whole, is in jeopardy of being seized, levied upon or
forfeited, or (c) miscellaneous taxes not willfully unpaid in an aggregate
amount not greater than $200,000 so long as by reason of such nonpayment no
material item or portion of Property of Borrower and its Subsidiaries, taken as
a whole, is in jeopardy of being seized, levied upon or forfeited.

         5.2 Preservation of Existence. Preserve and maintain their respective
existences, licenses, rights, franchises and privileges in the jurisdiction of
their formation and all authorizations, consents, approvals, orders, licenses,
permits, or exemptions from, or registrations with, any Governmental Agency that
are necessary for the transaction of their respective business, and qualify and
remain qualified to transact business in each jurisdiction in which such
qualification is necessary in view of their respective business or the ownership
or leasing of their respective Properties, except that Borrower's or any
Subsidiaries' failure to comply with the foregoing shall not constitute a
violation of this covenant to the extent that such failure does not cause
Borrower and its Subsidiaries, taken as a whole, to expend more than $100,000 in
the aggregate.

         5.3 Maintenance of Properties. Maintain, preserve and protect all of
their respective Properties and equipment in



                                      -47-
<PAGE>   52
good order and condition, subject to wear and tear in the ordinary course of
business, and not permit any waste of their respective Properties, except that
the failure to maintain, preserve and protect a particular item of Property or
equipment that is not of significant value, either intrinsically or to the

Date and from time to time thereafter upon Bank's reasonable request, either
directly or through Persons retained by Bank, to conduct a thorough annual bank
audit of the accounts receivable and inventories of Borrower and its
Subsidiaries and to have access to all of the books, records and employees of
Borrower and its Subsidiaries reasonably incidental to such bank audit and pay
the reasonable expenses of Bank or such Persons incurred in connection with such
bank audit.

occurrence of any change in the location of, or the addition of, any branch
office, any field office, any warehouse or any other place of business of
Borrower or any Subsidiary if such change requires any action by Bank in order
to maintain the validity or to perfect any Lien in favor of Bank or results in
or is accompanied by the acquisition or ownership of any property other than
Property not subject to a Lien in favor of the Bank pursuant to the Collateral
Documents; provided, however, that no such notification shall be required if the

trademarks to be acquired in connection therewith, together with such amendments
to the Collateral Documents as Bank may reasonably require, (ii) Bank shall have
reviewed and found satisfactory the historical compiled balance sheet, income
statement and cash flow for Teledyne, to the extent that any of such items have
been prepared, and (iii) Bank and/or its counsel shall have reviewed and found

              EVENTS OF DEFAULT AND REMEDIES UPON EVENT OF DEFAULT


         9.1 Events of Default. The existence or occurrence of any one or more
of the following events, whatever the reason therefor, shall constitute an Event
of Default:

                  (a) Borrower fails to pay any installment of principal when
         due, or Borrower fails to pay any installment of interest of any
         indebtedness on any of the Notes or any portion thereof, or to
         reimburse, or to pay any fee or any other amount due Bank under any
         Loan Document within five (5) days after the date when due; or

                  (b) Any failure to comply with Section 7.1(h) that is
         materially adverse to the interest of Bank; or

                  (c) Borrower, any of its Subsidiaries or any other Party fails
         to perform or observe any other term, covenant or agreement contained
         in any Loan Document on its part to be performed or observed; or

                  (d) Any representation or warranty made in any Loan Document
         or in any certificate, agreement, instrument or other document made or
         delivered by any Party pursuant to or in connection with any Loan
         Document proves to have been incorrect when made in any respect that is
         materially adverse to the interests of Bank; or

                  (e) Borrower or any of its Subsidiaries (i) fails to pay the
         principal, or any principal installment, of any present or future
         indebtedness for borrowed money or in connection with the purchase or
         lease of Property, or any guaranty of present or future indebtedness
         for borrowed money or issued in connection with the purchase or lease
         of Property, on its part to be paid, when due (or within any stated
         grace period), whether at the stated maturity, upon acceleration, by
         reason of required prepayment or otherwise, which equals or exceeds in
         the aggregate, $500,000 or (ii) fails to perform or observe any other
         term, covenant or agreement on its part to be performed or observed in
         connection with any present or future indebtedness for borrowed money
         or in connection with the purchase or lease of Property, or of any
         guaranty of present or future indebtedness for borrowed money or issued
         in connection with the purchase or lease of Property, which equals or
         exceeds in the aggregate, $500,000 if as a result of such failure any
         holder or holders thereof (or an agent or trustee on its or their
         behalf) has the right to declare such indebtedness due before the date
         on which it otherwise would become due, or



                                      -67-
<PAGE>   72
         has commenced judicial or nonjudicial action to collect such
         indebtedness or to foreclose or otherwise realize upon security held
         therefor, or has taken or is taking such other actions as might
         materially adversely affect the Collateral, the interests of Bank under
         the Loan Documents or the ability of Borrower or its Subsidiaries to
         pay and perform their Obligations under the Loan Documents; or

                  (f) Any Loan Document, at any time after its execution and
         delivery and for any reason other than the agreement of Bank or
         satisfaction in full of all the Obligations, ceases to be in full force
         and effect or is declared by a court of competent jurisdiction to be
         null and void, invalid or unenforceable in any respect which, in the
         reasonable opinion of Bank, is materially adverse to the interests of
         Bank; or any Party thereto denies that it has any or further liability
         or obligation under any Loan Document, or purports to revoke, terminate
         or rescind same; or

                  (g) A final judgment against Borrower or any of its
         Subsidiaries is entered for the payment of money in excess of $500,000
         and such judgment remains unsatisfied without procurement of a stay of
         execution within thirty (30) calendar days after the date of entry of
         judgment, or in any event later than five (5) days prior to the date of
         any proposed sale thereunder; or

                  (h) Borrower or any of its Subsidiaries is the subject of an
         order for relief in a bankruptcy case, or is unable or admits in
         writing its inability to pay its debts as they mature, or makes an
         assignment for the benefit of creditors; or applies for or consents to
         the appointment of any receiver, trustee, custodian, conservator,
         liquidator, rehabilitator or similar officer for it or for all or any
         part of its Property; or any receiver, trustee, custodian, conservator,
         liquidator, rehabilitator or similar officer is appointed without the
         application or consent of that Person and the appointment continues
         undischarged or unstayed for forty-five (45) calendar days; or
         institutes or consents to any bankruptcy, insolvency, reorganization,
         arrangement, readjustment of debt, dissolution, custodianship,
         conservatorship, liquidation, rehabilitation or similar case or
         proceedings relating to it or to all or any part of its Property under
         the Laws of any jurisdiction; or any similar case or proceeding is
         instituted without the consent of that Person and continues undismissed
         or unstayed for forty-five (45) calendar days; or any judgment, writ,
         warrant of attachment or execution or similar process is issued or
         levied against all or any material part of the Property of any such



                                      -68-
<PAGE>   73
         Person and is not released, vacated or fully bonded within forty-five
         (45) calendar days after its issue or levy; or

                  (i) Except as otherwise expressly permitted by any Loan
         Document or agreed to by Bank, any Lien on any Collateral created by
         any Loan Document, at any time after the execution and delivery of that
         Loan Document and for any reason other than satisfaction in full of all
         Obligations that is not attributable to any action taken or not taken
         by Bank, ceases or fails to constitute a valid, perfected and
         subsisting first priority Lien on the Collateral purported to be
         covered thereby; or

                  (j) Borrower or any Subsidiary thereof is dissolved or
         liquidated or all or substantially all of the assets of Borrower or any
         Subsidiary of Borrower are sold or otherwise transferred in violation
         of the provisions of this Agreement without the written consent of
         Bank; or

                  (k) An event or set of events occurs which has or could
         reasonably be expected to have a material adverse effect on (i) the
         validity or enforceability of this Agreement, any other agreement or
         document executed in connection with this Agreement, or the ability of
         the Bank to enforce its legal remedies thereunder; or (ii) the
         condition (financial or otherwise), business operations or prospects of
         Borrower and its Subsidiaries, taken as a whole, which could in turn
         reasonably be expected to impair the ability of Borrower and its
         Subsidiaries, taken as a whole, to perform their obligations under this
         Agreement and all such other documents and agreements; or

                  (l) A default or defined Event of Default occurs under any
         other agreement Borrower or any Subsidiary has with Bank or any
         affiliate of Bank, and is not cured within any applicable cure period;
         or

                  (m) The occurrence of any one or more of the following events
         with respect to Borrower or any Subsidiary, provided such event or
         events could reasonably be expected, in the judgment of Bank, to
         subject the Borrower to any tax, penalty or liability (or any
         combination of the foregoing) which, in the aggregate, could have a
         material adverse effect on the financial condition of Borrower with
         respect to a Plan:

                           (1) A reportable event shall occur with respect to a
                  Plan which is, in the reasonable judgment of Bank likely to
                  result in the termination of such Plan for purposes of Title
                  IV of ERISA.



                                      -69-
<PAGE>   74
                           (2) Any Plan termination (or commencement of
                  proceedings to terminate a Plan) or Borrower's full or partial
                  withdrawal from a Plan.

         9.2 Remedies Upon Event of Default. Without limiting any other rights
or remedies of Bank provided for elsewhere in this Agreement, or the Loan
Documents, or by applicable Law, or in equity, or otherwise:

                  (a) Upon the occurrence of any Event of Default other than an
         Event of Default described in Section 9.1(h):

                           (1) the Commitment to make Loans and all other
                  obligations of Bank and all rights of Borrower and any other
                  Parties under the Loan Documents shall terminate without
                  notice to or demand upon Borrower, which are expressly waived
                  by Borrower, except that Bank may waive the Event of Default
                  or, without waiving, determine, upon terms and conditions
                  satisfactory to Bank, to make further Loans; and

                           (2) Bank may declare all or any part of the unpaid
                  principal of the Notes, all interest accrued and unpaid
                  thereon and all other amounts payable under the Loan Documents
                  to be forthwith due and payable, whereupon the same shall
                  become and be forthwith due and payable, without protest,
                  presentment, notice of dishonor, demand or further notice of
                  any kind, all of which are expressly waived by Borrower.

Despite the foregoing, if, in Bank's opinion, a breach of any provision of this
Agreement (other than any provision specifically referred to in Section 9.1 or
Article 6), is capable of being remedied, and Borrower submits a written request
for a cure period along with its plan to remedy the default, then the breach
will not be considered an Event of Default under this Agreement for a period of
thirty (30) days after the date such breach first occurs; provided, however,
that Bank will not be obligated to make further Loans to Borrower during that
period.

                  (b) Upon the occurrence of any Event of Default described in
         Section 9.1(h):

                           (1) the Commitment to make Loans and all other
                  obligations of Bank and all rights of Borrower and any other
                  Parties under the Loan Documents shall terminate without
                  notice to or demand upon Borrower, which are expressly waived
                  by Borrower, except that Bank may waive the Event of Default
                  or, without waiving, determine, upon terms and conditions



                                      -70-
<PAGE>   75
         satisfactory to Bank, to make further Loans, which determination shall
         apply equally to, and shall be binding upon, Bank; and

                           (2) the unpaid principal of the Notes, all interest
                  accrued and unpaid thereon and all other amounts payable under
                  the Loan Documents shall be forthwith due and payable, without
                  protest, presentment, notice of dishonor, demand or further
                  notice of any kind, all of which are expressly waived by
                  Borrower.

                  (c) Upon the occurrence of any Event of Default, Bank without
         notice to or demand upon Borrower, which are expressly waived by
         Borrower, may proceed to protect, exercise and enforce their rights and
         remedies under the Loan Documents against Borrower and such other
         rights and remedies as are provided by Law or equity.

                  (d) The order and manner in which the Bank's rights and
         remedies are to be exercised shall be determined by Bank in its sole
         discretion, and all payments received by Bank shall be applied first to
         the costs and expenses (including attorneys' fees and disbursements) of
         Bank, and thereafter to the Obligations in such order as Bank may
         determine. For the purpose of computing Borrower's Obligations
         hereunder, under the Notes, and the Standby Letters of Credit, payments
         shall be applied, first, to the costs and expenses of Bank, as set
         forth above, second, to the payment of accrued and unpaid interest due
         under any Loan Documents to and including the date of such application
         (ratably, and without duplication, according to the accrued and unpaid
         interest due under each of the Loan Documents), third, to the ratable
         payment of all unpaid principal amounts due under any Loan Documents
         (including, for the purposes hereof, principal due under the Notes, and
         reimbursement due for payments made under Standby Letters of Credit)
         and fourth, to the payment of all other amounts (including fees) then
         owing to Bank under the Loan Documents. No application of payments will
         cure any Event of Default, or prevent acceleration, or continued
         acceleration, of amounts payable under the Loan Documents, or prevent
         the exercise, or continued exercise, of rights or remedies of Bank
         hereunder or thereunder or at Law or in equity. The term "attorneys'
         fees" as used in this Agreement shall include the allocated costs of
         in-house counsel.

                  (e) Upon the occurrence of any event that would be an Event of
         Default under Section 9.1(h) with the passage of time, Bank may take
         such action as Bank deems necessary to protect the interests of Bank
         under the Loan Documents.

                                   ARTICLE 10.
                                  MISCELLANEOUS

         10.1 Cumulative Remedies; No Waiver. The rights, powers, privileges and
remedies of Bank provided herein or in the Note or any other Loan Document are
cumulative and not exclusive of any right, power, privilege or remedy provided
by Law or equity. No failure or delay on the part of Bank in exercising any
right, power, privilege or remedy may be, or may be deemed to be, a waiver
thereof; nor may any single or partial exercise of any right, power, privilege
or remedy preclude any other or further exercise of the same or any other right,
power, privilege or remedy. The terms and conditions of Article 8 hereof are
inserted for the sole benefit of Bank and Bank may waive them in whole or in
part, with or without terms or conditions, in respect of any Loan or Standby
Letter of Credit, without prejudicing the Bank's rights to assert them in whole
or in part in respect of any other Loan or Standby Letter of Credit.

         10.2 Amendments; Consents. No amendment, modification, supplement,
extension, termination or waiver of any provision of this Agreement or any other
Loan Document, no approval or consent thereunder, and no consent to any
departure by Borrower or any other Party therefrom, may in any event be
effective unless in writing signed by Bank (and, in the case of amendments,
modifications or supplements of or to any Loan Document to which Borrower is a
Party, the approval in writing of Borrower), and then only in the specific
instance and for the specific purpose given.

         10.3 Costs, Expenses and Taxes. Borrower shall pay on demand the
reasonable costs and expenses of Bank in connection with the negotiation,
preparation, execution and delivery of the Loan Documents, and of Bank in
connection with the amendment, waiver, refinancing, restructuring,
reorganization (including a bankruptcy reorganization) and enforcement or
attempted enforcement of the Loan Documents, and any matter related thereto,
including, without limitation, filing fees, recording fees, title insurance
fees, appraisal fees, search fees and other out-of-pocket expenses and the
reasonable fees and out-of-pocket expenses of any legal counsel (including,
without limitation, costs and fees of Bank's in-house counsel), independent
public accountants and other outside experts retained by Bank, and including,
without limitation, any costs, expenses or fees incurred or suffered by Bank in
connection with or during the course of any bankruptcy or insolvency proceedings
of Borrower or any Subsidiary thereof. Borrower shall pay any and all
documentary and other taxes (other than income or gross receipts taxes generally
applicable to banks) and all costs, expenses, fees and charges payable or
determined



                                      -72-
<PAGE>   77
to be payable in connection with the filing or recording of this Agreement, any
other Loan Document or any other instrument or writing to be delivered hereunder
or thereunder, or in connection with any transaction pursuant hereto or thereto,
and shall reimburse, hold harmless and indemnify Bank from and against any and
all loss, liability or legal or other expense with respect to or resulting from
any delay in paying or failure to pay any tax, cost, expense, fee or charge or
that any of them may suffer or incur by reason of the failure of any Party to
perform any of its Obligations. Any amount payable to Bank under this Section
10.3 shall bear interest from the second Banking Day following the date of
demand for payment at the rate provided for in Section 3.6.

         10.4 Survival of Representations and Warranties. All representations
and warranties contained herein or in any other Loan Document, or in any
certificate or other writing delivered by or on behalf of any one or more of the
Parties to any Loan Document, will survive the making and repayment of the Loans
hereunder and the execution and delivery of the Note, and have been or will be
relied upon by Bank, notwithstanding any investigation made by Bank or on its
behalf.

         10.5 Notices. Except as otherwise expressly provided in the Loan
Documents: (a) All notices, requests, demands, directions and other
communications provided for hereunder or under any other Loan Document must be
in writing and must be mailed, telegraphed, telecopied, delivered or sent by
telex or cable to the appropriate party at the address set forth on the
signature pages of this Agreement or other applicable Loan Document or, as to
any party to any Loan Document, at any other address as may be designated by it
in a written notice sent to all other parties to such Loan Document in
accordance with this Section 10.5; and (b) Any notice, request, demand,
direction or other communication given by telegram, telecopier, telex or cable
must be confirmed within 48 hours by letter mailed or delivered to the
appropriate party at its respective address. Except as otherwise expressly
provided in any Loan Document, if any notice, request, demand, direction or
other communication required or permitted by any Loan Document is given by mail
it will be effective on the earlier of receipt or the third calendar day after
deposit in the United States mail with first class or airmail postage prepaid;
if given by telegraph or cable, when delivered to the telegraph company with
charges prepaid; if given by telex or telecopier, when sent; or if given by
personal delivery, when delivered.

         10.6 Execution of Loan Documents. Unless Bank otherwise specifies with
respect to any Loan Document, this Agreement and any other Loan Document may be
executed in any number of counterparts and any party hereto or thereto may
execute any counterpart, each of which when executed and delivered will be



                                      -73-
<PAGE>   78
deemed to be an original and all of which counterparts of this Agreement or any
other Loan Document, as the case may be, when taken together will be deemed to
be but one and the same instrument. The execution of this Agreement or any other
Loan Document by any party hereto or thereto will not become effective until
counterparts hereof or thereof, as the case may be, have been executed by all
the parties hereto or thereto.

         10.7 Binding Effect; Assignment. This Agreement and the other Loan
Documents shall be binding upon and shall inure to the benefit of the parties
hereto and thereto and their respective successors and assigns, except that
Borrower and/or its Affiliates may not assign their rights hereunder or there-
under or any interest herein or therein without the prior written consent of
Bank. Bank may, at any time and from time to time, sell, assign, pledge or
transfer participations in its rights hereunder or any interest herein provided
that any actual or potential participants, assignees, pledge holders or
transferees shall agree to treat all financial information exchanged as
confidential, and provided further that Borrower has given its prior consent
with respect to any proposed participant, or assignee. If a participation is
sold or the loan is assigned, the purchaser will have the right of set-off
against Borrower.

         10.8 Lien on Deposits and Property in Possession of any Bank. As
security for the prompt payment and performance of all Obligations, Borrower
hereby grants to Bank a Lien on and a security interest in all its right, title,
and interest in and to any and all deposit accounts now or hereafter maintained
with Bank and in and to any and all of its Property and the proceeds thereof now
or hereafter in the possession of Bank. If an Event of Default has occurred and
is continuing, Bank may exercise its rights under Article 9 of the Uniform
Commercial Code and other applicable Laws and apply any funds in any deposit
account maintained with it by Borrower and/or any Property of Borrower in its
possession against any Obligation owed to it by Borrower hereunder and/or under
any other Loan Document.

         10.9 Indemnity by Borrower. Borrower agrees to indemnify, save and hold
harmless Bank and its directors, officers, agents, attorneys and employees
(collectively the "Indemnitees") from and against: (a) Any and all claims,
demands, actions or causes of action that are asserted against any Indemnitee by
any person (other than Bank) if the claim, demand, action or cause of action
directly or indirectly relates to a claim, demand, action or cause of action
that such person asserts or may assert against Borrower or any Affiliate of
Borrower or any officer, director or shareholder of Borrower relating to the
Commitments, the use or contemplated use of proceeds of any Loan or Standby
Letter of Credit, or the



                                      -74-
<PAGE>   79
relationship of Borrower and Bank under this Agreement; (b) Any and all claims,
demands, actions or causes of action if the claim, demand, action or cause of
action arises out of or relates to any action or inaction by Borrower or its
Subsidiaries in connection with the Commitments or the use or contemplated use
of proceeds of any Loan or Standby Letter of Credit; (c) Any administrative or
investigative proceeding by any Governmental Agency arising out of or related to
a claim, demand, action or cause of action described in clauses (a) or (b)
above; and (d) Any and all liabilities, losses, costs or expenses (including
attorneys' fees (including the allocated cost of in-house counsel) and
disbursements and other professional services) that any Indemnitee suffers or
incurs as a result of the assertion of any foregoing claim, demand, action or
cause of action; provided that no Indemnitee shall be entitled to
indemnification of or any loss caused by its own gross negligence or willful
misconduct. Promptly after receipt by Bank of notice of any third-party claim to
which the indemnification obligations hereunder would apply, Bank shall give
notice thereof to Borrower in writing, stating the information then available to
Bank regarding the amount and nature of such claim, but the failure to do so
promptly notify Borrower shall not affect Borrower's obligations under this
paragraph 10.9 unless such failure materially prejudices Borrower's right to
participate in the contest of such claim, demand, action or cause of action.
Borrower shall have the right to defend against all such claims, demands,
actions or causes of action, at Borrower's cost and expense, with counsel
selected by Borrower and reasonably satisfactory to Bank. The Borrower shall
regularly keep Bank informed as to the status of, and any material developments
relating to, any claim subject to this paragraph 10.9, and shall respond
promptly in writing to any reasonable requests by Bank for information or other
data concerning such claim. Any obligation or liability of Borrower to any
Indemnitee under this Section 10.9 shall be and hereby is covered and secured by
the Loan Documents and the Collateral, and shall survive the expiration or
termination of this Agreement and the repayment of all Loans and the payment and
performance of all other Obligations owed to Bank.

         10.10 Environmental Indemnity And Other Matters.

                  (a) Borrower agrees that it shall indemnify, defend and hold
         Indemnitees, and each of them, harmless from and against any claim,
         action, suit, proceeding, loss, cost, damage, liability, deficiency,
         fine penalty, punitive damage or expense (including, without
         limitation, attorneys' fees and disbursements), resulting from, arising
         out of, or based upon (i) the presence, release, use, generation,
         discharge, storage or disposal of any hazardous or toxic wastes or
         materials on, under, in or about, or the transportation of any such
         wastes to or



                                      -75-

         from, any Property of Borrower, or (ii) the violation, or alleged
         violation, of any statute, ordinance, order, rule, regulation, permit,
         judgment or license relating to the use, generation, release,
         discharge, storage, disposal or transportation of hazardous or toxic
         wastes or materials on, under, in or about, to or from, any such
         Property. This indemnity shall include, without limitation, any damage,
         liability, fine, penalty, punitive damage, cost or expense (including
         without limitation all post-foreclosure clean-up and removal costs and
         expenses) arising from or out of any claim, action, suit or proceeding
         for personal injury (including sickness, disease or death), tangible or
         intangible property damage, compensation for lost wages, business
         income, profits, or other economic loss, damage to the natural
         resources or the environment, nuisance, pollution, contamination, leak,
         spill, release or other adverse effect on the environment. The
         obligations of Borrower and the rights of Indemnitees under this
         Section are in addition to and not in substitution of the obligations
         of Borrower and rights of Indemnitees under the laws and regulations
         cited above and any other similar applicable laws. The obligations and
         indebtedness of Borrower, and the rights of Indemnitees, under this
         Section and the laws and regulations cited above, notwithstanding
         anything contained herein or in any other document or agreement which
         may be construed to the contrary, (i) shall not be secured by the
         Collateral Documents, and shall not be subject to California Code of
         Civil Procedure Sections 580a, 580d, 726 or any other anti-deficiency
         laws, and (ii) shall survive the foreclosure of any deed of trust, the
         repayment of the Loans, and the termination of the Notes and other Loan
         Documents. As used herein, the terms "toxic" or "hazardous" wastes,
         substances or materials shall include, without limitation, all those so
         designated and all those in any way regulated by any of the above-cited
         laws or regulations, or any other present or future environmental or
         other similar laws or regulations. Whenever practicable, upon obtaining
         actual knowledge of any event that would entitle Bank to be indemnified
         under this Section, Bank shall endeavor to provide notice to Borrower
         of such fact and Bank shall cooperate with Borrower to endeavor to
         minimize the liabilities for which Bank is entitled to be indemnified.

                  (b) Upon demand by Bank, Borrower will defend any
         investigation, action or proceeding alleging the presence of any
         hazardous substance in any such location, which affects the real
         property owned by the Borrower or any of its Subsidiaries or which is
         brought or commenced against Bank, whether alone or together with
         Borrower or any other person, all at Borrower's own cost and by counsel
         to be



                                      -76-
<PAGE>   81
         approved by Bank in the exercise of its reasonable judgment. In the
         alternative, Bank may elect to conduct its own defense at the expense
         of Borrower.

                  (c) Bank and its agents and representatives will have the
         right at any reasonable time to enter and visit the properties of
         Borrower and its Subsidiaries and any other place where any property is
         located for the purposes of observing the real property owned by
         Borrower or any of its Subsidiaries, taking and removing soil or
         groundwater samples, and conducting tests on any part of the real
         property owned by Borrower or any of its Subsidiaries. Bank is under no
         duty, however, to visit or observe the real property owned by Borrower
         or any of its Subsidiaries or to conduct tests, and any such acts by
         Bank will be solely for the purposes of preserving Bank's rights under
         this Agreement and the other Loan Documents. No site visit, observation
         or testing by Bank will result in a waiver of any default of Borrower
         or impose any liability on Bank. In no event will any site visit,
         observation or testing by Bank be a representation that hazardous
         substances are or are not present in, on or under the real property
         owned by Borrower or any of its Subsidiaries, or that there has been or
         will be compliance with any law, regulation or ordinance pertaining to
         hazardous substances or any other applicable governmental law. Neither
         Borrower nor any other party is entitled to rely on any site visit,
         observation or testing by Bank. Bank owes no duty of care to protect
         Borrower or any other party against, or to inform Borrower or any other
         party of, any hazardous substances or any other adverse condition
         affecting the real property owned by Borrower or any of its
         Subsidiaries. Bank will not be obligated to disclose to Borrower or any
         other party any report or findings made as a result of, or in
         connection with, any site visit, observation or testing by Bank. In
         each instance, Bank will give Borrower reasonable notice before
         entering the real property owned by Borrower or any of its Subsidiaries
         or any other place Bank is permitted to enter under this paragraph.
         Bank will make reasonable efforts to avoid interfering with the use of
         the real property owned by Borrower or any of its Subsidiaries or any
         other property in exercising any rights provided in this paragraph.

                  (d) Borrower's obligations to Bank under this Section, except
         the obligation to give notices to Bank, shall survive termination of
         this Agreement and repayment of Borrower's obligations to Bank under
         this Agreement, and shall also survive as unsecured obligations after
         any acquisition by Bank of the collateral securing this Agreement.

         10.11 Nonliability of the Bank. Borrower acknowledges and agrees that:

                  (a) Any inspections of Collateral made by or through Bank are
         for purposes of administration of the Loan only and Borrower is not
         entitled to rely upon the same;

                  (b) By accepting or approving anything required to be
         observed, performed, fulfilled or given to Bank pursuant to the Loan
         Documents, including any certificate, financial statement, insurance
         policy or other document, Bank shall not be deemed to have warranted or
         represented the sufficiency, legality, effectiveness or legal effect of
         the same, or of any term, provision or condition thereof, and such
         acceptance or approval thereof shall not constitute a warranty or
         representation to anyone with respect thereto by Bank;

                  (c) The relationship between Borrower and Bank is, and shall
         at all times remain, solely that of a borrower and lender; Bank shall
         not under any circumstance be construed to be a partner or joint
         venturer of Borrower or its Affiliates; Bank shall not under any
         circumstance be deemed to be in a relationship of confidence or trust
         or a fiduciary relationship with Borrower or its Affiliates, or to owe
         any fiduciary duty to Borrower or its Affiliates; Bank undertakes or
         assumes no responsibility or duty to Borrower or its Affiliates to
         select, review, inspect, supervise, pass judgment upon or inform
         Borrower or its Affiliates of any matter in connection with their
         Property, any Collateral held by Bank or the operations of Borrower or
         its Affiliates; Borrower and its Affiliates shall rely entirely upon
         their own judgment with respect to such matters; and any review,
         inspection, supervision, exercise of judgment or supply of information
         undertaken or assumed by Bank in connection with such matters is solely
         for the protection of Bank and neither Borrower nor any other Person is
         entitled to rely thereon; and

                  (d) Bank shall not be responsible or liable to any Person for
         any loss, damage, liability or claim of any kind relating to injury or
         death to Persons or damage to Property caused by the actions, inaction
         or negligence of Borrower and/or its Affiliates and Borrower hereby
         indemnifies and holds Bank harmless from any such loss, damage,
         liability or claim.

         10.12 No Third Parties Benefited. This Agreement is made for the
purpose of defining and setting forth certain obligations, rights and duties
of Borrower and Bank in connection with the Loans, and is made for the sole
protection of Borrower and Bank, and Bank's successors and assigns. Except as



                                      -78-

<PAGE>   83
provided in Section 10.9, no other Person shall have any rights of any nature
hereunder or by reason hereof.

         10.13 Confidentiality. Bank agrees to hold any confidential information
that it may receive from Borrower pursuant to this Agreement in confidence,
except for disclosure: (a) To legal counsel, accountants and other professional
advisors to Borrower or Bank; (b) To regulatory officials having jurisdiction
over that Bank; (c) As required by Law or legal process or in connection with
any legal proceeding to which Bank is a party; (d) To another financial
institution in connection with a disposition or proposed disposition of all or
part of Bank's interests hereunder; and (e) To prospective purchasers of
Collateral in connection with any disposition thereof; provided that nothing in
this Section shall be construed to create or give rise to any fiduciary duty on
the part of Bank to Borrower or to create or give rise to any relationship of
confidence or trust between Bank and Borrower.

         10.14 Further Assurances. Borrower and its Subsidiaries shall, at their
expense and without expense to the Bank, do, execute and deliver such further
acts and documents as any Bank from time to time reasonably requires for the
assuring and confirming unto Bank of the rights hereby created or intended now
or hereafter so to be, or for carrying out the intention or facilitating the
performance of the terms of any Loan Document, or for assuring the validity,
perfection, priority or enforce- ability of any Lien under any Loan Document.

         10.15 Integration. This Agreement, together with the other Loan
Documents, comprises the complete and integrated agreement of the parties on the
subject matter hereof and supersedes all prior agreements, written or oral, on
the subject matter hereof. In the event of any conflict between the provisions
of this Agreement and those of any other Loan Document, the provisions of this
Agreement shall control and govern; provided that the inclusion of supplemental
rights or remedies in favor of Bank in any other Loan Document shall not be
deemed a conflict with this Agreement. Each Loan Document was drafted with the
joint participation of the respective parties thereto and shall be construed
neither against nor in favor of any party, but rather in accordance with the
fair meaning thereof.

         10.16 Governing Law. Except to the extent otherwise provided therein,
each Loan Document shall be governed by, and construed and enforced in
accordance with, the local Laws of California; provided that the local Laws of
California shall not apply with respect to any foreclosure of real Property
Collateral located outside California, and in no event shall California Code of
Civil Procedure Sections 726 and/or 580a and/or 580b and/or 580d apply to
any such foreclosure outside



                                      -79-
<PAGE>   84
of California or to the right of Bank to obtain a deficiency judgment for all
Obligations remaining due following such foreclosure.

         10.17 Severability of Provisions. Any provision in any Loan Document
that is held to be inoperative, unenforceable or invalid as to any party or in
any jurisdiction shall, as to that party or jurisdiction, be inoperative,
unenforceable or invalid without affecting the remaining provisions or the
operation, enforceability or validity of that provision as to any other party or
in any other jurisdiction, and to this end the provisions of all Loan Documents
are declared to be severable.

         10.18 Headings. Article and Section headings in this Agreement and the
other Loan Documents are included for convenience of reference only and are not
part of this Agreement or the other Loan Documents for any other purpose.

         10.19 Time of the Essence. Time is of the essence of the Loan
Documents.

         10.20 Arbitration.

                  (a) This paragraph concerns the resolution of any
         controversies or claims between Borrower and Bank, including but not
         limited to those that arise from:

                           (i) This Agreement (including any renewals,
                  extensions or modifications of this Agreement);

                           (ii) Any document, agreement or procedure related to
                  or delivered in connection with this Agreement;

                           (iii) Any violation of this Agreement; or

                           (iv) Any claims for damages resulting from any
                  business conducted between Borrower and Bank, including claims
                  for injury to persons, property or business interests (torts).

                  (b) At the request of Borrower or Bank, any such controversies
         or claims will be settled by arbitration in accordance with the United
         States Arbitration Act. The United States Arbitration Act will apply
         even though this Agreement provides that it is governed by California
         law.

                  (c) Arbitration proceedings will be administered by the
         American Arbitration Association and will be subject
         to its commercial rules of arbitration.



                                      -80-
<PAGE>   85
                  (d) For purposes of the application of the statute of
         limitations, the filing of an arbitration pursuant to this paragraph is
         the equivalent of the filing of a lawsuit, and any claim or controversy
         which may be arbitrated under this paragraph is subject to any
         applicable statute of limitations. The arbitrators will have the
         authority to decide whether any such claim or controversy is barred by
         the statute of limitations and, if so, to dismiss the arbitration on
         that basis.

                  (e) If there is a dispute as to whether an issue is
         arbitrable, the arbitrators will have the authority to resolve any such
         dispute.

                  (f) The decision that results from an arbitration proceeding
         may be submitted to any authorized court of law to be confirmed and
         enforced.

                  (g) The procedure described above will not apply if the
         controversy or claim, at the time of the proposed submission to
         arbitration, arises from or relates to an obligation to Bank secured by
         real property located in California. In this case, both Borrower and
         Bank must consent to submission of the claim or controversy to
         arbitration. If both parties do not consent to arbitration, the
         controversy or claim will be settled as follows:

                           (i) Borrower and Bank will designate a referee (or a
                  panel of referees) selected under the auspices of the American
                  Arbitration Association in the same manner as arbitrators are
                  selected in Association-sponsored proceedings;

                           (ii) The designated referee (or the panel of
                  referees) will be appointed by a court as provided in
                  California Code of Civil Procedure Section 638 and the
                  following related sections;

                           (iii) The referee (or the presiding referee of the
                  panel) will be an active attorney or a retired judge; and

                           (iv) The award that results from the decision of the
                  referee (or the panel) will be entered as a judgment in the
                  court that appointed the referee, in accordance with the
                  provisions of California Code of Civil Procedure Sections 644
                  and 645.

                  (h) This provision does not limit the right of Borrower or
         Bank to:

                           (i) exercise self-help remedies such as setoff;



                                      -81-
<PAGE>   86
                           (ii) foreclose against or sell any real or personal
                  property collateral; or

                           (iii) act in a court of law, before, during or after
                  the arbitration proceeding to obtain:

                                    (A) an interim remedy; and/or

                                    (B) additional or supplementary remedies.

                  (i) The pursuit of or a successful action for interim,
         additional or supplementary remedies, or the filing of a court action,
         does not constitute a waiver of the right of Borrower or Bank,
         including the suing party, to submit the controversy or claim to
         arbitration if the other party contests the lawsuit. However, if the
         controversy or claim arises from or relates to an obligation to Bank
         which is secured by real property located in California at the time of
         the proposed submission to arbitration, this right is limited according
         to the provision above requiring the consent of both Borrower and Bank
         to seek resolution through arbitration.

                  (j) If Bank forecloses against any real property securing this
         Agreement, Bank has the option to exercise the power of sale under the
         deed of trust or mortgage, or to proceed by judicial foreclosure.

         10.21 Personal Liability of Responsible Officials. In the absence of
actual fraud, no Certificate of a Responsible Official delivered to the Bank
hereunder shall create personal liability to the Bank on the part of such
Responsible Official for payment or performance of any of the Obligations or
otherwise under the Loan Documents.

         10.22 Prior Agreement Superseded. This Agreement supersedes the Third
Amended and Restated Loan Agreement, and any credit outstanding thereunder shall
be deemed to be outstanding under this Agreement.

         10.23 Teledyne Indemnity. To the extent permitted by the Teledyne
Acquisition Agreement, Borrower and Jay-El Products, Inc. each hereby assign to
Bank the indemnity provisions (and all rights and benefits attendant thereto)
granted to either of them under the Teledyne Acquisition Agreement; provided,
however, that Borrower and Jay-El Products, Inc. shall be entitled to enforce
all of such rights and to collect any proceeds in connection therewith so long
as no Default has occurred and is continuing under this Agreement. Borrower
agrees to use its best efforts, and to cause Jay-El Products,



                                      -82-
<PAGE>   87
Inc. to use its best efforts, to permit an assignment of such indemnity
provisions to Bank.

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

any portion of any Loan bearing interest at an IBOR Rate may result in Bank
incurring additional costs, expenses and/or liabilities. Borrower therefore
agrees to pay the prepayment fee described in Section 3.5 of this Agreement if
the portion is prepaid, whether voluntarily or by reason of acceleration,
including acceleration upon any sale of the Collateral. Borrower agrees that the
fee represents a reasonable estimate of the prepayment costs, expenses and/or

offer an IBOR Rate to Borrower is sufficient and independent consideration for
this agreement to pay the fee.
