                  Section 2.2 EFFECTIVE TIME. The Merger will become effective
at the time (the "Effective Time") the Agreement of Merger substantially in the
form set forth as Exhibit A hereto (the "Agreement of Merger") is filed with the
appropriate government officials in accordance with the California Corporations
Code and any other applicable Law. Buyer, Acquisition and the Company shall
execute and deliver the Agreement of Merger prior to the Closing Date.

                  Section 2.3 EFFECTS OF THE MERGER. The Merger shall have the
effects set forth herein, in the Agreement of Merger and in the California
Corporations Code. As of the Effective Time, the Company shall be a wholly-owned
Subsidiary of Buyer.

                  Section 2.4 CONVERSION OF THE STOCK INTO CASH. At the
Effective Time, (a) each ZMP Share shall be converted into the right to receive
a portion of the Merger Consideration determined as set forth in Section 2.8
hereof, subject to the adjustments set forth on Section 2.10 hereof, and (b)
each share of common stock of Acquisition issued and outstanding immediately
before the Effective Time shall remain issued, outstanding and unchanged as
validly issued, fully paid and non-assessable shares of common stock of the


                                       9


Surviving Corporation of the Merger; provided, however, that the Merger
Consideration, including any subsequent payments under Section 2.10 hereof and
any distributions from the Escrow Account, will be payable only to the holders
of ZMP Shares immediately prior to the Effective Time, such that the owners of
shares of Acquisition common stock who become owners of the Company common stock
as a result of the Merger are not entitled to take part in any distributions of
Merger Consideration. After the Effective Time and until surrendered for
payment, each Company stock certificate outstanding and each warrant and/or
option certificate immediately prior to the Effective Time (other than any such
certificate representing Dissenting Shares) will represent only the right to
receive the Merger Consideration. The Collins Option shall be cancelled as of
the Effective Time and represent only the right to receive the Merger
Consideration.

                  Section 2.5 STOCK HELD BY THE COMPANY. Notwithstanding any
other provision of this Agreement, any shares of ZMP Common Stock held by the
Company, by Acquisition or by Buyer, or by the wholly-owned Subsidiaries of any
of them, will be canceled at the Effective Time.

                  Section 2.6 CLOSING. The Closing of the transaction provided
for in this Agreement shall be held in the offices of Latham & Watkins, 885
Third Avenue, New York, NY (unless the parties hereto otherwise agree in
writing), on the Closing Date.

                  Section 2.7 CLOSING DATE. The "Closing Date" shall be the
later of April 23, 1999 and the third business day of the satisfaction or waiver
of all the conditions to Closing set forth in Article V or as otherwise agreed
to among the parties; provided, however, the Closing Date shall not be later
than the Termination Date. The Agreement of Merger shall be filed with the
appropriate officials on the Closing Date.

                  Section 2.8 PAYMENT OF CONSIDERATION. Subject to the terms and
conditions of this Agreement, the aggregate consideration payable by Buyer and
Acquisition for the Company shall be $41,000,000 plus (i) the aggregate exercise
prices payable under any options or warrants outstanding at the Effective Time
to purchase shares of ZMP Common Stock and (ii) an amount equal to the Collins
Note Amount (the "Purchase Price"). The Purchase Price shall be paid or applied
at the Closing and thereafter as hereafter provided in this Section 2.8 and in
Sections 2.10, 2.11, 2.12 and 8.3 hereof.

                  (a) At the closing, the Purchase Price shall first be paid or
applied as follows: (i) Buyer shall cause the Surviving Corporation to pay to
the holders of the TCW Notes in immediately available funds the outstanding
amount of such TCW Notes (including accrued interest and any prepayment
penalties and other amounts due thereon) as of the Closing Date, and Buyer shall
be liable for such payment if not made (it being understood that immediately
prior to the Closing the Company will utilize its available cash to pay down the
TCW Notes); (ii) Buyer shall cause the Surviving Corporation to pay to the
holders of the Bank Debt in immediately available funds the outstanding amount
of such Bank Debt (including accrued interest and any prepayment penalties and
other amounts due thereon) as of the Closing Date, and Buyer shall be liable for
such payment if not made; (iii) Buyer shall pay to or as directed by the
Shareholders' Representative in immediately available funds amounts sufficient
to cover all of the expenses, as of the Closing Date and reasonably estimated to
be incurred thereafter, of any 



                                       10


of the Company, ARA, the Selling Shareholders and the Shareholders'
Representative incident to the negotiation, preparation and performance of this
Agreement and the other Transactions Documents and the transactions contemplated
hereby or thereby and the process pursuant to which the Company and ARA were
sold and any proposed disposition or sale contemplated to a third party or
otherwise of all or any portion of the business of the Company or ARA, including
the fees, expenses and disbursements of the investment bankers, accountants and
counsel; and (iv) Buyer shall cause the Surviving Corporation to pay in
immediately available funds the Success Bonuses to each of the persons and in
the amounts as directed by Shareholders' Representative, and Buyer shall be
liable for such payment if not made (it being understood and agreed that any
additional amounts that may be payable with respect to the Success Bonuses shall
be paid in accordance with Section 8.3(f)). The amount of the Purchase Price
remaining after the payments described in clauses (i) through (iv) above is
hereinafter referred to as the "Base Equity Price".

                  (b) The Base Equity Price shall be paid or applied as follows:
(i) Buyer shall cause the Surviving Corporation to retain (for ultimate payment
to the holders of Dissenting Shares if and to the extent required to be so paid)
an amount equal to the Base Equity Price multiplied by a fraction, the numerator
of which is the number of Dissenting Shares, and the denominator of which is the
number of ZMP Shares plus the number of Dissenting Shares (the "Dissenting
Shares Amount"); (ii) Buyer shall deliver to the Escrow Agent (I) an amount
equal to the sum of (x) $3,000,000 and (y) if, and only if, there are any
Dissenting Shares, an additional $200,000 for deposit in one escrow account (the
"Escrow Account") and (II) an amount equal to the sum of $750,000 for deposit in
a separate escrow account (the "Glendale Escrow Account"); and (iii) Buyer shall
cause the Surviving Corporation to pay to each holder of ZMP Shares or options
or warrants to acquire ZMP Shares an amount equal to such holder's Applicable
Percentage of the Base Equity Price remaining after the retention and payment
described in clauses (i) and (ii) above. There shall be deducted from any
payment due to a holder under clause (iii) above (x) any exercise price payable
by such holder under such option or warrant to acquire ZMP Shares and (y) any
amount owed by such holder to ZMP or ARA, including, in the case of Collins, the
Collins Note Amount. As used herein, "Merger Consideration" means the aggregate
amount per ZMP Share payable in the Merger, including any amounts payable to the
holders of ZMP Shares pursuant to this Section 2.8 and Sections 2.10, 2.11, 2.12
and 8.3 hereof.

                  Notwithstanding anything to the contrary set forth herein, the
amount of Merger Consideration to be received by the holders of ZMP Shares upon
surrender of their share certificates, letter of transmittal and other required
documentation shall be reduced by the amount, if any, the Company is required to
deduct and withhold with respect to the making of such payment under the Code,
or any provision of state, local or foreign tax law; provided that if any
amounts are so deducted and withheld as Taxes, such amounts shall be treated as
having been paid to the holder of such ZMP Shares.

                  Section 2.9 PERFORMANCE AT THE CLOSING.

                  (a) DELIVERIES BY ACQUISITION. At the Closing, and subject to
Section 2.9(b) below, Buyer, Acquisition and the Surviving Corporation will make
the payments contemplated by Section 2.8.



                                       11


                  (b) SURRENDER OF CERTIFICATES REQUIRED FOR PAYMENT. Any
payment described herein to any Selling Shareholder is conditional upon the
surrender to Buyer by such Selling Shareholder of its stock certificates and any
documentation evidencing any option to acquire ZMP Shares and a letter of
transmittal substantially in the form attached hereto as Exhibit E. Buyer agrees
to make payment immediately upon such surrender (i) by check delivered to each
Selling Shareholder to its most recent registered address on the Company's stock
records, or, if a Selling Shareholder provides Buyer with an alternate address
to which payment should be delivered, to such alternate address or (ii) if a
Selling Shareholder provides Buyer with wire instructions for delivery of such
payment, in immediately available funds to the bank and account therein
identified.

                  No interest shall be paid or accrued on any amount payable
upon the surrender of ZMP Shares. If payment is to be made to a Person other
than the Person in whose name a share certificate surrendered is registered, it
shall be a condition of payment that the share certificate so surrendered shall
be properly endorsed (signature guaranteed) or otherwise in proper form for
transfer and that the Person requesting such payment shall pay all transfer and
other taxes required by reason of the payment to a Person other than the
registered holder of the share certificate, or establish to the satisfaction of
Buyer that such tax has been paid or is not applicable, or provide assurance
reasonably satisfactory to Buyer that any such tax will be paid by such Person.

                  (c) DELIVERIES BY SHAREHOLDERS' REPRESENTATIVE. Shareholders'
Representative shall, to the extent it has access thereto and to the information
required thereunder, provide any forms or certificates required by any state or
local taxing authorities to relieve Buyer of any obligation to withhold any
portion of the Merger Consideration.

                  Section 2.10 POST-CLOSING PURCHASE PRICE ADJUSTMENT.

                  Following the Closing, the Merger Consideration shall be
adjusted as provided herein to reflect changes in Net Working Capital as
determined based on the Closing Date Statement of Net Working Capital compared
to the Target Net Working Capital.

                  (a) Within 60 days following Closing, Buyer and the Surviving
Corporation shall cause to be prepared and delivered to the Shareholders'
Representative a statement of the current assets (the "Current Assets") and the
current liabilities (the "Current Liabilities") of the Company and ARA as of the
close of business on the Friday immediately preceding the Closing (the "Closing
Date Statement of Net Working Capital") along with supporting materials and
calculations and a calculation of the amount, if any, due to the Selling
Shareholders or Buyer as a result of the adjustments set forth in this Section
2.10. The Current Assets and Current Liabilities set forth on the Closing Date
Statement of Net Working Capital shall be determined in accordance with GAAP
applied in the manner, and according to the principles, applied in the
preparation of the Audited Financial Statements as of and for the period ended
June 26, 1998; provided, however, that in determining Current Assets and Current
Liabilities, the exclusions and adjustments described on Schedule 2.10 shall be
given effect. Upon the request of Shareholders' Representative, Buyer and the
Company shall take such steps as may be reasonably necessary to permit a
representative of the Shareholders' Representative to observe all procedures
undertaken in the preparation of the Closing Date Statement of Net Working
Capital and to provide the 



                                       12


Shareholders' Representative access at all reasonable times to the personnel,
properties, books and records of the Company and ARA for the purpose of
reviewing and ascertaining the accuracy of the Closing Date Statement of Net
Working Capital.

                  (b) Within 30 days after receipt of the Closing Date Statement
of Net Working Capital, the Shareholders' Representative shall, in a written
notice to Buyer, either accept the Closing Date Statement of Net Working Capital
or describe in reasonable detail, in writing, any proposed adjustments and the
reasons therefor. No such written notice shall be delivered to Buyer if the net
proposed adjustments in the aggregate amount to an increase in Net Working
Capital of less than $25,000. If the Buyer has not received such notice of
proposed adjustments within such 30 day period, the Shareholders' Representative
will be deemed irrevocably to have accepted the Closing Date Statement of Net
Working Capital. In the event that Shareholders' Representative and Buyer are
not able to agree on the Net Working Capital within 30 days from and after the
receipt by Buyer of any adjustments proposed by the Shareholders'
Representative, such dispute shall be submitted to Arthur Andersen LLP for
computation or verification in accordance with the provisions of this Agreement.
Such firm shall determine as promptly as practicable, but in any event within 30
days of the date on which such dispute is referred to such firm, whether the
Closing Date Statement of Net Working Capital was prepared in accordance with
the standards set forth in this Agreement on the basis solely of the written
submissions of the parties, and whether and to what extent (if any) Net Working
Capital as shown thereon requires adjustment. The results of such accounting
firm's report shall be binding, conclusive and non-appealable upon Shareholders'
Representative, the Selling Shareholders and Buyer, and such accounting firm's
fees and expenses shall be borne equally by Buyer, on one hand, and the Selling
Shareholders (through a reduction in any amount owed to them under this Section
2.10 or, if no such amount is owed to them, through a payment out of the Escrow
Account) on the other. Buyer and the Shareholders' Representative will jointly
instruct the Escrow Agent, in writing, to make any such payment.

                  (c) Upon acceptance of the Closing Date Statement of Net
Working Capital by Buyer or the resolution of any disputes, (i) if Net Working
Capital on the Closing Date as so determined is greater than the Target Net
Working Capital by more than $25,000, the Merger Consideration shall be
increased by such amount and Buyer shall promptly, but no later than 5 days
after final determination, pay or cause the Surviving Corporation to pay to each
Selling Shareholder such Selling Shareholder's Applicable Percentage of the
amount of such excess, together with interest thereon from the Closing Date to
the date of payment thereof as determined below, and (ii) if Net Working Capital
on the Closing Date as so determined is less than the Target Net Working Capital
by more than $25,000, the Shareholders' Representative and the Buyer shall
promptly, but no later than 5 days after such final determination, instruct the
Escrow Agent in writing to pay to Buyer from the Escrow Account the amount of
such difference, together with interest thereon from the Closing Date to the
date of payment thereof as determined below.

                  (d) For the purposes of this Section 2.10, interest will be
payable at the applicable federal rate (as defined in Section 1274 of the Code),
or, if that rate is no longer established or published, a comparable interest
rate. For purposes of this Section 2.10, interest shall be calculated based on a
365 day year and the actual number of days elapsed.



                                       13


                  Section 2.11 DISSENTING SHARES. Notwithstanding anything in
this Agreement to the contrary, shares of ZMP Common Stock that are issued and
outstanding immediately prior to the Effective Time and that are held by a
stockholder who has the right (to the extent such right is available by law) to
demand and receive payment of the fair value of such holder's stock pursuant to
California law shall not be converted into the right to receive the Merger
Consideration (unless and until such holder shall have failed to perfect or
shall have effectively withdrawn or lost such right under California law, as the
case may be) (such shares, the "Dissenting Shares"), but the holder thereof
shall only be entitled to such rights as are granted by California law. If such
holder shall have so failed to perfect or shall have effectively withdrawn or
lost such right, such holder's shares of ZMP Common Stock shall thereupon no
longer be Dissenting Shares, but shall be deemed to have been converted at the
Effective Time into the right to receive the Merger Consideration (without any
interest thereon), and the Merger Consideration payable in respect thereof and
in respect of all other ZMP Shares shall be adjusted to yield the results that
would have obtained if such shares had been treated as ZMP Shares rather than
Dissenting Shares at the Closing. If the holder of any shares of ZMP Common
Stock shall become entitled to receive payment for such shares pursuant to
Section 1300 of the California Corporations Code ("Section 1300 Payment") then
such payment shall be made by the Surviving Corporation with no cost or other
liability to any of the Selling Shareholders or the Shareholders'
Representative, except as provided or referred to in the next sentence. Pursuant
to Section 7.1(4), the Buyer Indemnitees shall be indemnified against all Losses
incurred by them (including Section 1300 Payments and payments required
hereunder out of the Dissenting Share Amount) in connection with or as a result
of the existence of Dissenting Shares at the Closing if and to the extent that
such Losses or payments exceeds the Dissenting Share Amount.

                  Section 2.12 SPECIAL PURCHASE PRICE ADJUSTMENT

Following the Closing, the Merger Consideration shall be adjusted as follows:

                  (a)(i) If a Boeing Contract is executed and delivered by
Boeing and ARA on or prior to the Boeing Determination Date, within 10 business
days of such execution and delivery Buyer shall cause to be prepared and
delivered to the Shareholders' Representative (x) a statement, along with a copy
of a Boeing Contract, and if requested by Shareholders' Representative, and
calculations, setting forth the amount due to the Buyer, if any, as a result of
the calculations set forth in Section 2.12(a)(iii) or (y) a statement that no
amount is due to Buyer as a result of the calculations set forth in Section
2.12(a)(iii).

                  (ii) Within 10 business days after receipt of a statement
delivered pursuant to Section 2.12(a)(i)(x), the Shareholders' Representative
shall, in a written notice to the Buyer, either accept such statement or
describe in reasonable detail any proposed adjustments and the reasons therefor.
If Buyer has not received such notice of proposed adjustments within such 10
business day period, the Shareholders' Representative will be deemed to
irrevocably to have accepted such statement. In the event that the Shareholders'
Representative and the Buyer are not able to agree on such statement within 10
business days of receipt by Buyer of any adjustments proposed by Shareholders'
Representative, such dispute shall be submitted to Arthur Andersen LLP for
computation or verification in accordance with this Agreement.



                                       14


                  (iii) Upon acceptance by the Shareholders' Representative of
the statement delivered pursuant to Section 2.12(a)(i)(x) or the resolution of
any disputes, if the Proposed Boeing Revenue is less than the Boeing Target
Amount, the Merger Consideration will be decreased by an amount equal to the
product of (x) the Boeing Target Amount minus the Proposed Boeing Revenue and
(y) the Fixed Multiplier. If the Merger Consideration is so decreased, the
Shareholders' Representative and the Buyer shall promptly, but in no event later
than five days after such final determination, instruct the Escrow Agent in
writing to pay Buyer from the Escrow Account the amount of such decrease.

                  (b) If no Boeing Contract has been executed and delivered by
Boeing and ARA on or prior to the Boeing Determination Date, the Buyer shall
cause to be prepared and delivered to Shareholders' Representative a statement
pursuant to Section 2.12(a)(i)(x) setting forth the amount due to the Buyer as a
result of the calculations set forth in Section 2.12(a)(iii) assuming for
purposes of such calculation that Proposed Boeing Revenue equals zero.

                 (c) Notwithstanding anything to the contrary herein, the
parties hereto agree that any amounts payable to the Buyer under or pursuant to
this Section 2.12 will be paid solely out of the Escrow Account, in accordance
with this Agreement, and none of the Selling Shareholders will have any
obligation to make (or otherwise with respect to) any such payments other than
from the Escrow Account. Buyer acknowledges that the payments contemplated
hereunder may exceed the amount on deposit in the Escrow Account and that such
payments may exhaust the Escrow Account and that Buyer shall not be entitled to
payment from any other source, including the Glendale Escrow Account.

                 (d) Notwithstanding anything to the contrary herein, if a part
or parts set forth on Schedule A is not set forth in the Boeing Contract as
executed and delivered by the parties and, in the Shareholders' Representative's
reasonable and good faith judgement, such part or parts may be contained in a
subsequent Boeing Contract to be executed and delivered prior to the Boeing
Determination Date the Boeing Target Amount shall be recomputed for purposes of
the calculation set forth in Section 2.12(iii) to exclude such part or parts. If
a subsequent Boeing Contract containing the part or parts so excluded is
executed and delivered prior to the Boeing Determination Date, a separate
calculation shall be made pursuant to Section 2.12(iii) with respect to such
part or parts, utilizing a target amount based solely on such part or parts. If
such subsequent Boeing Contract containing the part or parts so excluded is not
executed and delivered prior to the Boeing Determination Date, a separate
calculation shall be made pursuant to Section 2.12(b) with respect to such part
or parts, utilizing a target amount based solely on such part or parts.

                 (e) Buyer, the Company and ARA agree to use their commercially
reasonable efforts to execute and deliver the Boeing Contract and to negotiate
its terms and conditions in good faith. Notwithstanding the foregoing sentence
or anything to the contrary herein, Buyer, the Company and ARA shall be under no
obligation to execute or deliver a Boeing Contract or any other contract with
Boeing that is not on substantially the terms and conditions set forth in the
Boeing Proposal.



                                       15

standing under the respective Laws of the jurisdiction of its incorporation or
organization and (ii) has all necessary corporate power and authority to own its
properties and assets and to carry on its businesses as now conducted except
where the failure to be so organized or validly existing, to be in good
standing, or to have such power and authority does not constitute a material
adverse effect on the ability of either Buyer or Acquisition to consummate the
transactions contemplated by this Agreement.

                  (b) CAPITAL STOCK. All of the outstanding shares of capital
stock of each of Buyer and Acquisition will, at the Closing Date, be duly

clear of any Encumbrances, other than Permitted Encumbrances.

                  (c) AUTHORIZATION. Each of Buyer and Acquisition has the
necessary corporate power and authority to execute, deliver and perform this
Agreement and the other Transaction Documents and to consummate the transactions
contemplated by this Agreement and the other Transaction Documents. The
execution, delivery and performance of this Agreement and the other Transaction
Documents by each of Buyer and Acquisition has been duly and validly authorized
by the respective Boards of Directors of Buyer and of Acquisition and by all
other necessary corporate action on the part of Buyer and Acquisition. Each of
the Agreement and the Voting Agreement constitutes (and the Escrow Agreement

Disclosure Schedule, the execution, delivery and performance by each of Buyer
and Acquisition of this Agreement and the other Transaction Documents and the

and/or the occurrence of any act or event or otherwise under (A) the charter
documents or bylaws of either Buyer or Acquisition, (B) any Law to which either
Buyer or Acquisition is subject, or (C) any Contract to which either Buyer or
Acquisition is a party or (ii) require any consent, waiver, authorization or

premises and records of the Company and ARA for such purpose.

                  (h) NO BROKERS OR FINDERS. No agent, broker, finder, or
investment or commercial banker, or other Person or firm engaged by or acting on
behalf of Buyer in connection with the negotiation, execution or performance of
this Agreement or the transactions contemplated by this Agreement, is or will be
entitled to any broker's or finder's or similar fee or other commission as a
result of this Agreement or such transactions.

                  Section 3.2 REPRESENTATIONS AND WARRANTIES BY THE COMPANY. As
of the date hereof and as of the Closing Date (except to the extent any of the
following speaks as of a specific date, such as the date hereof), the Company
represents and warrants to, and agrees with, Buyer and Acquisition as follows:

                  (a) ORGANIZATION AND RELATED MATTERS. Each of the Company and

qualified or licensed to do business as a foreign corporation in good standing
in all jurisdictions in which the character or the location of the assets owned,
operated or leased by any of them or the nature of the business conducted by any
of them requires licensing or qualification, except in the cases of clauses (ii)
and (iii) where the failure to have such power and authority or to be so
qualified or licensed does not constitute a Material Adverse Effect. All
jurisdictions referred to in clause (iii) above are set forth in Section 3.2A of
the Disclosure Schedule. All corporate actions taken by the Company and ARA have
been duly authorized, and the Company and ARA have not taken any action that 



                                       17

violation of any provision of its Certificate of Incorporation or By-Laws. The
Board of Directors of the Company, at a meeting duly called and held, has (i)
determined that this Agreement and the transactions contemplated hereby,
including the Merger, taken together are fair to and in the best interest of the

the outstanding capital stock of ARA free and clear of all Encumbrances. The
authorized capital stock of the Company consists of 108,695 shares of common
stock, $.001 par value, of which 105,435 shares are issued and outstanding and

warrants, convertible securities or other rights to subscribe for or purchase,
or Contracts or other obligations to issue or grant any rights to acquire, any
Equity Securities or Equity Equivalents of the Company or ARA, or to restructure
or recapitalize the Company or ARA. There are no outstanding Contracts of the
Company or ARA to repurchase, redeem or otherwise acquire any Equity Securities
of any of such Persons or to provide funds to, or make any investment (in the
form of a loan, capital contribution or otherwise) in, any other Person. All
Equity Securities of the Company and ARA are duly authorized, validly issued and
outstanding and are fully paid and nonassessable. There are no preemptive rights
in respect of any Equity Securities of the Company or ARA. Any Equity Securities
of the Company and ARA which were issued and reacquired by any of such Persons
were so reacquired (and, if reissued, so reissued) in compliance with all
applicable Laws, and the Company and ARA have no outstanding obligation or
liability with respect thereto. Other than the Company's ownership of ARA and as
set forth on Section 3.2B of the Disclosure Statement, there are no other
corporations, partnerships, joint ventures, associations or other entities in
which the Company or ARA owns, of record or beneficially, any Equity Securities
or other interest or any right (contingent or otherwise) to acquire the same.
Neither the Company nor ARA is a member of (nor is any part of the business
conducted through) any partnership, nor is the Company or ARA a participant in
any joint venture or similar arrangement. The minute books of the Company and
ARA contain accurate records of all meetings and accurately reflect all other
actions taken by the stockholders and Boards of Directors of the Company and
ARA. Complete and accurate copies of all such minute books and of the stock
register of the Company and ARA have been provided by the Company to the Buyer.
Section 3.2B of the Disclosure Schedule sets forth the total amount of
Indebtedness and the total amount of cash on hand of the Company and ARA on a
consolidated basis, in each case as of the date hereof. Section 3.2B of the
Disclosure Schedule also sets forth all of the stockholders of the Company, the
number of shares of ZMP Common Stock owned by each, and all amounts owed to the
Company or ARA by any holders of ZMP Common Stock.

                  (c) FINANCIAL STATEMENTS; CHANGES; CONTINGENCIES.

                      (i) The Company has delivered to Buyer (i) audited
consolidated balance sheets for the Company and ARA at the end of each fiscal
year ending in June 1996, 1997 and 1998 and the related statements of
operations, cash flow and changes in stockholders' equity for the periods then
ended (collectively, the "Audited Financial Statements") and (ii) 



                                       18


copies of the unaudited consolidated balance sheet (the "Interim Balance Sheet")
for the Company and ARA at February 20, 1999 and the related statement of
operations, cash flow and changes in stockholders' equity for the period then
ended (collectively with the Interim Balance Sheet, the "Unaudited Financial
Statement" and, together with the Audited Financial Statements, the "Financial
Statements"). The Audited Financial Statements have been examined by the
Company's Auditors, whose reports thereon are included with such financial
statements. The Audited Financial Statements have been prepared in conformity
with GAAP, except for changes, if any, required by GAAP and disclosed therein,
consistently applied throughout the periods covered thereby. Each statement of
operations, cash flow and changes in stockholders' equity in the Audited
Financial Statements (i) was prepared in accordance with the books of account
and other financial records of the Company and ARA and (ii) presents fairly the
results of operations, cash flow and changes in stockholders' equity of the
Company and ARA for the periods covered, and each balance sheet (i) was prepared
in accordance with the books of account and other financial records of the
Company and ARA and (ii) presents fairly the financial condition of the Company
and ARA as of its respective date. Such Audited Financial Statements reflect all
adjustments necessary for a fair presentation. At the date of the most recent
such balance sheet, neither the Company nor ARA had any Liabilities (actual,
contingent or accrued) that, in accordance with GAAP, should have been shown or
reflected therein but were not.

                      (ii) The Unaudited Financial Statements have been prepared
in conformity with GAAP as used in preparing the Audited Financial Statements,
provided that such Unaudited Financial Statements do not include footnotes, and
(i) were prepared in accordance with the books of account and other financial
records of the Company and ARA and (ii) present fairly the consolidated
financial position of the Company and ARA as of such date and the consolidated
results of operations, cash flow and changes in stockholders' equity of the
Company and ARA for such period. At February 20, 1999, neither the Company nor
ARA had any Liabilities (actual, contingent or accrued) that, in accordance with
GAAP as used in preparing the Audited Financial Statements, should have been
shown or reflected in such Unaudited Financial Statements but were not except as
otherwise described in Section 2.8(a)(iii). Accruals for expenses relating to
the transactions contemplated by this Agreement and the other Transaction
Documents and for the Success Bonuses reflected on the Interim Balance sheet
were $194,000 and $380,000, respectively.

                      (iii) Since June 26, 1998 neither the Company nor ARA has
incurred any Liabilities (whether accrued, absolute, contingent or otherwise)
that would be required to be reflected or reserved against in a balance sheet of
the Company and ARA prepared in accordance with GAAP as used in preparing the
Audited Financial Statements, except Liabilities that are reflected or disclosed
in the financial statements referred to in this Section 3.2(c) or were incurred
after February 20, 1999 in the ordinary course of business, consistent with past
practice. Neither the Company nor ARA has any Liabilities (whether accrued,
absolute, contingent or otherwise) that do not relate primarily to the ownership
of its assets, the conduct of its Business or its existence as a corporation.
Other than the TCW Notes or as set forth on Section 3.2B of the Disclosure
Schedule, neither the Company nor ARA has any Liability to any Shareholder of
the Company.

                  The books of account and other financial records of the
Company and ARA: (i) reflect all items of income and expense and all assets and
Liabilities required to be reflected 



                                       19


therein in accordance with GAAP and (ii) are in all material respects complete
and correct, and do not contain or reflect any material inaccuracies or
discrepancies. Since June 26, 1998, the Company and ARA have maintained systems
of internal accounting controls sufficient to provide reasonable assurance that
material transactions are recorded as necessary to permit preparation of
financial statements in conformity with GAAP and to maintain asset
accountability.

                  Except to the extent, if any, reserved for on the Unaudited
Financial Statements, all Receivables reflected therein arose from the sale of
Inventory or services to Persons not affiliated with ARA or the Company and in
the ordinary course of the Business consistent with past practice other than (i)
notes payable from Collins in the aggregate amount of approximately $512,000 and
(ii) a note payable from a former employee in the approximate amount of $16,000
and except as reserved against on the Unaudited Financial Statements, constitute
or will constitute, as the case may be, only valid and, to the best knowledge of
the Company and ARA, undisputed claims of the Company or ARA and, to the best
knowledge of the Company and ARA, are not subject to valid claims of set off or
other defenses or counterclaims other than normal cash discounts accrued in the
ordinary course of the Business consistent with past practice.

                  Subject to amounts reserved therefor on the Unaudited
Financial Statements, the values at which all Inventories are carried therein
reflect the historical inventory valuation policy of the Company and ARA of
stating such Inventories at the lower of cost (determined on the first in, first
out method) or market value. Except as set forth in Section 3.2C of the
Disclosure Schedule, the Company or ARA, as the case may be, has good and
marketable title to the Inventories free and clear of all Encumbrances other
than Permitted Encumbrances. The Inventories do not consist of any items held on
consignment. Except as set forth on Section 3.2C of the Disclosure Schedule,
neither the Company nor ARA is under any obligation or liability with respect to
accepting returns of items of Inventory or merchandise in the possession of
their customers.

                  Except as reserved against on the Unaudited Financial
Statements, the Inventories do not consist of, in any material amount, items
that are obsolete, damaged or slowmoving. The Inventories are in good and
merchantable condition, are suitable and usable for the purposes for which they
are intended and are in a condition such that they can be sold in the ordinary
course of the Business consistent with past practice.

                  (d) CONDUCT IN THE ORDINARY COURSE; ABSENCE OF CERTAIN
CHANGES, EVENTS AND CONDITIONS. Since June 26, 1998, except as disclosed in
Section 3.2D of the Disclosure Schedule, (i) the Business of the Company and ARA
has been conducted only in the ordinary course and consistent with past practice
and (ii) there has not been, occurred or arisen (and, to the Company's
knowledge, there is no threatened change in or event affecting the Company or
ARA that, taking into account the likelihood of its occurring, would reasonably
be characterized as) any change in or event affecting the Company or ARA that
has had or would reasonably be expected to have had a Material Adverse Effect.
As amplification and not limitation of the foregoing, except as disclosed in
Section 3.2D of the Disclosure Schedule, since June 26, 1998 neither the Company
nor ARA has:

         excess of $50,000;

                  (iii) made any loan (other than loans to employees in the

         the Business consistent with past practice) and other than acquisitions
         of assets relating to the recent relocation of ARA's facilities;

                  (vii) sold, assigned, transferred, leased, subleased, licensed

                  (xi) incurred any Indebtedness, other than trade payables
         incurred in the ordinary course of the Business consistent with past
         practice and other than any increase in the Indebtedness described in
         Section 2.8(a)(i) and (ii);

                  (xii) amended, canceled, waived or modified in any material

         license;

                  (xv) made any material election or settled or compromised any

The sole and exclusive business activity in which the Company is engaged is the
ownership, directly or indirectly, of all of the outstanding capital stock
issued by ARA. Additionally, except as set forth on Section 3.2E of the
Disclosure Schedule, the only property, assets and rights (whether tangible or
intangible) owned by the Company is all of the outstanding capital stock issued
by ARA.

                  (f) MATERIAL CONTRACTS. Section 3.2F of the Disclosure
Schedule lists each contract to which the Company or ARA is a party or to which

                  (g) AUTHORIZATION; NO CONFLICTS. The execution, delivery and
performance of this Agreement and the Escrow Agreement and the transactions

Company's Board of Directors and by all other necessary corporate action on the
part of the Company. This Agreement has been duly executed 



                                       23


and delivered by the Company and constitutes the legally valid and binding
obligation of the Company, enforceable against the Company in accordance with
their terms except as such enforceability may be limited by bankruptcy,
insolvency, reorganization, moratorium and other similar Laws and equitable
principles relating to or limiting creditors rights generally. The execution,
delivery and performance of this Agreement and the Escrow Agreement by the
Company and the execution, delivery and performance of any related agreements or
contemplated transactions by the Company will not (i) violate, or constitute a
breach or default (whether upon lapse of time, giving of notice or both) under,
the charter documents or by-laws of any of such entities, (ii) violate, or
constitute a breach or default (whether upon lapse of time, giving of notice or
both) under any Contract to which the Company or ARA is a party, including
without limitation any Material Contract, (iii) result in the imposition of any
Encumbrance against any asset or properties of the Company or ARA, (iv) require

any Law or Order except with respect to clause (ii), (iii) or (iv) of this
Section 3.2(g), for any such matters that would not reasonably be expected,
singly or in the aggregate, to have a Material Adverse Effect.

                  (h) TAX AND OTHER RETURNS AND REPORTS. Each of the Company and
ARA has timely filed or will file (or, where permitted or required, its
respective direct or indirect parents have timely filed or will file) all
material Tax Returns required to be filed and have paid (or will pay) all Taxes
shown thereon as owing for all taxable periods ending on or before the Closing
Date (a "Pre-Closing Period"). As of the Closing Date, each of the Company and
ARA shall have made payments of estimated taxes as required by Law (taking into
account the tax effects of the transactions contemplated hereby) for (i) the
pre-closing portion of the Straddle Period (as defined in and determined under
Section 4.8(a)), and (ii) taxable periods ending on or prior to the Closing Date
but for which a Tax Return is not yet due. Adequate accruals and reserves have
been provided in the books and records of the Company and ARA, and, to the
extent required by GAAP in the Audited Financial Statements referred to in
Section 3.2(c) above or delivered or to be delivered to Buyer, for all Taxes
whether or not due and payable and whether or not disputed. Neither the Company
nor ARA has elected to be treated as a consenting corporation under Section
341(f) of the Code. Section 3.2G of the Disclosure Schedule lists the date or
dates through which the IRS and any other Governmental Entity have examined the
United States federal income Tax Returns and any other Tax Returns of the
Company and ARA. All required Tax Returns, including amendments to date, have
been prepared in good faith and are complete and accurate in all material
respects. Except as set forth on Section 3.2H of the Disclosure Schedule, there
are no deficiencies for Taxes claimed or proposed by any Governmental Entities
that have not yet been fully paid or settled. Except as set forth on Section
3.2H of the Disclosure Schedule, there are no pending audits relating to Taxes
of the Company or ARA or, to the best of the Company's knowledge, threatened
material audits or investigations relating to Taxes of the Company or ARA.
Neither the Company nor ARA has waived any statute of limitations in respect of
Taxes or agreed to any extension of time with respect to a Tax assessment or
deficiency. Neither the Company nor ARA is a party to any Tax allocation or
sharing agreement. Neither the Company nor ARA has been a member of an
Affiliated Group filing a consolidated federal or a combined or unitary State or
Local Tax Return (other than a group the common parent of which was the Company
or Certified Holding Corporation, a Delaware 



                                       24


corporation). There are no liens for Taxes (other than for current Taxes not yet
due and payable) on the assets of the Company or ARA. None of the assets of the
Company or ARA (i) directly or indirectly secures any debt the interest on which
is tax exempt, (ii) is property that is required to be treated as being owned by
any other person under the applicable tax law, or (iii) is "tax-exempt use
property" for federal income tax purposes. Neither the Company nor ARA has
agreed to make or is required to make any adjustment under Section 481(a) of the
Code by reason of a change in accounting method or otherwise. Neither the
Company nor ARA is obligated to make, as a result of an event connected with the
transaction contemplated by this Agreement, any "excess parachute payment" as
defined in Section 280G of the Code.

                  (i) REAL AND PERSONAL PROPERTY; TITLE TO PROPERTY; LEASES.
Neither the Company nor ARA owns any real property. The Company and ARA have
title to or other right to use, free of Encumbrances, all items of real
property, including fees, leaseholds, easements and all other interests in real
property, and such other assets and properties that are material to the
Business, except for Permitted Encumbrances. All material tangible assets and
properties of the Company and ARA that are used in or intended to be used in the
Business or otherwise used by the Company or ARA or reflected on the Financial
Statements (other than Inventory sold or otherwise disposed of in the ordinary
course of business) are in a good state of maintenance and repair (except for
ordinary wear and tear) and are adequate for the Business. Section 3.2I of the
Disclosure Schedule sets forth each parcel of Leased Real Property. The Company
has made available to the Buyer true and complete copies of each lease for each
parcel of Leased Real Property (the "Leases") and, to the extent in the
possession of the Company or ARA, all the title insurance policies, title
reports, surveys, mortgages, easements, certificates of occupancy, environmental
reports and audits, appraisals, Permits, other title documents relating to the
Leased Real Property. Either the Company or ARA, as the case may be, is in
peaceful and undisturbed possession of all space that it is currently entitled
to possess under such Lease and no rights adverse to the rights of the Company
or ARA, to the knowledge of ARA or the Company, have been asserted by any Person
and there are no contractual or legal restrictions that preclude or materially
restrict the ability to use the premises for the purposes for which they are
currently being used. Neither the Company nor ARA has leased or subleased any
parcel or any portion of any parcel of Leased Real Property to any other Person.
Neither the Company nor ARA holds any option, right of first refusal or similar
right to purchase any additional parcel or real property or any portion thereof
or interest therein. All material Leased Real Property held by the Company or
ARA as lessee are held under valid, binding and enforceable leases, and neither
ARA nor the Company has received any written notice of any default under any
such Lease. To the knowledge of the Company and ARA, there are no condemnation
proceedings or eminent domain proceedings of any kind pending or threatened
against the Leased Real Property. To the knowledge of the Company and ARA, there
are no material latent defects or material adverse physical conditions affecting
the Leased Real Property or any of the facilities, buildings, structures,
erections, improvements, fixtures, fixed assets and personalty of a permanent
nature annexed, affixed or attached to, located on or forming part of the Leased
Real Property.

                  (j) INTELLECTUAL PROPERTY. The Company and ARA have rights to
and ownership of all Intellectual Property required for use in connection with
the Business. The Company and ARA have in all material respects performed all
obligations required to be performed by them, and they are not in default in any
material respect under any Contract relating to any Owned Intellectual Property
or Licensed Intellectual Property. Neither the 



                                       25


Company nor ARA has received any notice to the effect (and is not otherwise
aware) that the Owned Intellectual Property or the Licensed Intellectual
Property or any use by the Company and ARA of any such property conflicts with
or allegedly conflicts with or infringes the rights of any Person. Section 3.2J
of the Disclosure Schedule sets forth a true and complete list and a brief
description, including a complete identification of each patent and patent
application and each registration or application for registration thereof, of
all Owned Intellectual Property and Section 3.2J of the Disclosure Schedule sets
forth a true and complete list and a brief description, including a description
of any license or sublicense thereof, of all Licensed Intellectual Property.
Except as disclosed on Section 3.2J of the Disclosure Schedule, the rights of
the Company or ARA, as the case may be, in or to Owned Intellectual Property do
not conflict with or infringe in any material respect on the rights of any other
Person. Except as disclosed in Section 3.2J of the Disclosure Schedule: (i) all
the Owned Intellectual Property is owned by either the Company or ARA, as the
case may be, free and clear of any Encumbrance and (ii) no Actions have been
made or asserted or are pending (nor, to the best knowledge of the Company, has
any such Action been threatened) against the Company or ARA either (A) based

licenses and sublicenses:

                  (i)      such license or sublicense, together with all
                           ancillary documents delivered pursuant to the first

                  (iii)    no Actions have been made or asserted or are pending
                           (nor, to the knowledge of the Company, has any such
                           Action been threatened) against the Company or ARA
                           either (A) based upon or challenging or seeking to
                           deny or restrict the use by the Company or ARA of any

                           Licensed Intellectual Property is being licensed,
                           sublicensed or used in violation of any patents or
                           trademarks, or any other rights of any Person; and

                  (iv)     to the knowledge of the Company no Person is using
                           any patents, copyrights, trademarks, service marks,
                           trade names, trade secrets or similar property that
                           are confusingly similar to the Licensed Intellectual
                           Property or that infringe upon the Licensed
                           Intellectual Property or upon the rights of the
                           Company or ARA therein.

                  (k) LEGAL PROCEEDINGS AND CERTAIN LABOR MATTERS. Except as set
forth on Section 3.2K of the Disclosure Schedule, there is no Order or Action
pending or, to the knowledge of the Company, threatened against or affecting the

material adverse effect on the Company's ability to perform this Agreement, or
on the transactions contemplated by this Agreement. Except as set forth on

the knowledge of the Company, threatened any civil, criminal or administrative
actions, suits, demands, claims, hearings, notices of violation, investigations,

in design, manufacture, materials or workmanship including, without limitation,
any failure to warn or alleged breach of express or implied warranty or
representation, relating to any product manufactured, distributed or sold by or
on behalf of the Company or ARA that would individually or in the aggregate
reasonably be expected to have a Material Adverse Effect. Section 3.2K of the
Disclosure Schedule sets forth a true and complete list of (i) all matters
referred to in the preceding sentence and (ii) all material product recalls or
material written post-sales warnings ("Recalls") and all investigations,
considerations or decisions made by the Company or, to the knowledge the
Company, by any other Person, concerning a Recall relating to any product
manufactured, distributed or sold by or on behalf of the Company or ARA. Except

                  (l) PERMITS. Except as disclosed on Section 3.2L of the
Disclosure Schedule, the Company and ARA hold all material Permits that are
required by any Governmental Entity to permit each of them to conduct its
respective businesses as now conducted, including, without limitation, all
authorizations required by the FAA and CAA, and all such Permits are valid and
in full force and effect and will remain so upon consummation of the

imminent. The Company and ARA have not violated any such Permit in any material
respect and each is in compliance with such Permits in all material respects.

                  (m) COMPLIANCE WITH LAW. The businesses of the Company and ARA
are being conducted in compliance with applicable Laws and Orders issued by any
Governmental Entities, except to the extent that any such noncompliance is
reasonably likely to result in losses, liabilities, obligations, damages, costs
or expenses (including, without limitation, fines and penalties) of less than
$37,500 singly or $225,000 in the aggregate. Neither the Company nor ARA has
received any written notice to the effect that any currently existing
circumstances are likely to result in a failure of the Company or ARA to comply
with, or a violation by the Company of, any Laws, in either case which such
failure to comply or violation would be reasonably likely to result in losses,
liabilities, obligations, damages, costs or expenses (including, without
limitation, fines and penalties) in excess of $37,500 singly or $225,000 in the
aggregate. Section 3.2M of the Disclosure Schedule sets forth a brief
description of each Order to which the Company or ARA is a party applicable to
the Company or ARA or any of the assets of the Business.

                  All products sold by the Company or ARA pursuant to
qualification requirements established by the Company's or ARA's customers are
and have been produced in a manner consistent in all material respects with such
requirements. The Company and ARA hold and have held all necessary
qualifications for its products from its customers pursuant to which sales were
made to such customers. Except as set forth on Section 3.2M of the Disclosure
Schedule, neither the Company nor ARA has received notification that any
qualifications for the Company's or ARA's products as established by the
Company's or ARA's customers have been revoked or terminated as a result of the
failure of products manufactured by the Company or ARA to meet the
specifications required by such qualifications, and to the knowledge of the
Company, no such revocation or termination is threatened.

                  (n) DIVIDENDS AND OTHER DISTRIBUTIONS. Except as set forth on
Section 3.2N of the Disclosure Schedule, there has been no dividend or other
distribution of assets or securities, or any declaration regarding the foregoing

interest in any property used in or pertaining to the Business; (ii) no such
Person is indebted or otherwise obligated to the Company or ARA; and (iii) the
Company and ARA are not indebted or otherwise obligated to any such Person,
except for amounts due under normal arrangements applicable to all employees
generally as to salary or reimbursement of ordinary business expenses not
unusual in amount or significance or under Arrangements or Plans disclosed on
Section 3.2R of the Disclosure Schedule. The consummation of the transactions
contemplated by this Agreement will not result in any material benefit or
payment (severance or other) arising or becoming due from the Company or ARA or
the successor or assign of any thereof to any Person.

                  (p) INTERCOMPANY TRANSACTIONS. Except to the extent stated in
or disclosed pursuant to Sections 3.2(b) or 3.2(o), the Company and ARA have not
engaged in any transaction with any of the stockholders of the Company or any
other Affiliate of any of the 



                                       28

any thereof to any of the Selling Shareholders or any Affiliate of any of the
Selling Shareholders.

                  (q) ENVIRONMENTAL COMPLIANCE. Except as set forth in Section
3.2Q of the Disclosure Schedule, since June 14, 1988, and, to the knowledge of
the Company, prior to June 14, 1988, (i) each of the Company and ARA has been in

of any actions, causes of actions, claims, investigations, demand, information
requests or notices by any person or entity alleging liability or potential
liability pursuant to or non-compliance with any Environmental Law; (iii) there
are no conditions existing which would reasonably be expected to form the basis
of a claim against the Company or ARA pursuant to or for the violation or
non-compliance with any Environmental Law; and (iv) there are no circumstances
which would reasonably be expected to prevent or interfere in the future with
the Company's and ARA's material compliance with all Environmental Laws. The
Company and ARA hold all material Permits relating to environmental matters that
are required by any Governmental Entity to permit each of them to conduct their
respective businesses as now conducted, and all such Permits are valid and in
full force and effect and will remain so upon consummation of the transactions
contemplated by this Agreement. To the knowledge of the Company, no suspension,
cancellation or termination of any of such Permits is threatened or imminent.
All past proceedings and investigations and non-compliance with Law or Permits
relating to environmental matters have been resolved without any pending,
on-going or future cost or liability, except as set forth in Section 3.2Q of the
Disclosure Schedule. Notwithstanding the generality of any other representations
and warranties in this Agreement, this Section 3.2(q) shall be deemed to contain
the only representations and warranties in this Agreement with respect to
matters relating to Environmental Laws.

                  (C) The Company, all Employee Plans, and ARA are in compliance
         in all material respects with the applicable provisions of ERISA and
         all other Laws applicable with respect to all such Employee Plans. The

         their assets, or arising out of such Employee Plans, and all such
         Employee Plans have been operated in compliance in all material
         respects with their terms.

                  (D) All obligations of the Company and ARA under each such

                                       30





                      (B) Each such plan is qualified in form and operation 
         under Section 401(a) of the Code and each trust under each such plan 
         is exempt from tax under Section 501(a) of the Code. No event has 
         occurred that will or, to the knowledge of the Company, could give 
         rise to disqualification or loss of tax-exempt status of any such 
         plan or trust under such sections. No event has occurred that will 
         or, to the knowledge of the Company, could subject any such plans to 
         tax under Section 511 of the Code. To the knowledge of the Company, 
         no non-exempt prohibited transaction (within the meaning of Section 
         4975 of the Code) or non-exempt party-in-interest transaction 
         (within the meaning of Section 406 of ERISA) has occurred with 
         respect to any such plan and none of the Company, ARA or any 
         Employee Plan fiduciary has otherwise violated the provisions of 
         Part 4 of Title I, Subtitle B of ERISA.

                      (iii) Title IV Plan. No Employee Plan listed in Section
3.2R of the Disclosure Schedule is a plan subject to Title IV of ERISA. None of
the Company, ARA or any ERISA Affiliate has, within the last six years, (A)
maintained any employee benefit plan which has been subject to Title IV of
ERISA; or (B) maintained, administered or contributed to any multiemployer plan
as defined in Section 4001(a)(3) of ERISA. Neither the Company nor ARA has any
liability with respect to any employee benefit plan sponsored by any current or
former ERISA Affiliate (other than the Company or ARA).

                      (iv) Health Plans. All group health plans of the Company
and ARA and any trade or business (whether or not incorporated) that is a member
of a group of which Company is a member and which is under common control within
the meaning of Section 414(b), (c), (m) and (o) of the Code ("ERISA Affiliates")
have been operated in material compliance with the group health plan
continuation coverage requirements of Section 4980B of the Code to the extent
such requirements are applicable. Neither Company nor ARA provides health care
or any other non-pension benefits to any employees after their employment is
terminated, other than as required by part 6 of subtitle B of Title I of ERISA
or Section 4980B of the Code or benefits that continue for a brief period of
time after termination of employment (for example, for the balance of the month
in which an employee terminates), or has ever promised to provide any such
post-termination welfare benefits.

                      (v) Fines and Penalties. There has been no act or omission
by the Company or ARA that has given rise to or, to the knowledge of the
Company, may give rise to fines, penalties, taxes, or related charges under

                      (vi) Deductibility of Payments; No Acceleration or
Creation of Rights. There is no contract, agreement, plan or arrangement
covering any employee or former employee of the Company or ARA that,
individually or collectively, provides for the payments by the Company or ARA of
any amount (A) that is not deductible under Section 162(a)(1) or 404 of the Code
or (B) that is an "excess parachute payment" pursuant to Section 280G of the
Code. Except for the Success Bonuses and as otherwise set forth on Section 3.2R
of the Disclosure Schedule, neither the execution and delivery of this Agreement
by the Company and ARA nor the consummation of the transactions contemplated
hereby will result in the acceleration or creation of any rights of any person
to benefits under any Employee Plan (including, without limitation, the
acceleration of the vesting or exercisability of any stock options or warrants,
the 


                                       31


acceleration of the vesting of any restricted stock, the acceleration of the
accrual or vesting of any benefits under any pension plan or the acceleration or
creation of any rights under any severance, parachute or change in control
agreement).

                      (vii) The current value of assets held in the trust
maintained in connection with that certain Deferred Compensation Plan and Trust
Agreement dated as of March 2, 1992 by and among ZMP, Inc., Gene Schiappa (as
trustee) and Charles A. Collins, as amended from time to time (the "Deferred
Compensation Plan"), is not less than the amount of liabilities accumulated
under the Deferred Compensation Plan.

                  (s) INSURANCE. Section 3.2S of the Disclosure Schedule lists
all insurance policies and bonds that are maintained by the Business. All such
policies and bonds that are material to the Business are in full force and
effect and protect the Company and ARA against such losses and risks as is
consistent with industry practice. Neither the Company nor ARA has received any
notice of any material increase in premiums with respect to, or cancellations or
non-renewal of, any of such policies. Neither the Company nor ARA is in default
in any material respect under any such policy or bond.

                  (t) NO BROKERS OR FINDERS. Other than fees to be paid to
Bowles Hollowell Conner & Co. (which fees are to be paid from the Purchase
Price), no agent, broker, finder, or investment or commercial banker, or other
Person or firm engaged by or acting on behalf of the Company or ARA in
connection with the negotiation, execution or performance of this Agreement or
the transactions contemplated by this Agreement, is or will be entitled to any
broker's or finder's or similar fee or other commission as a result of this
Agreement or such transactions.

                  (u) ABSENCE OF CERTAIN ARRANGEMENTS. Neither the Company nor
ARA, and to the Company's or ARA's knowledge no director, officer, agent, or
employee of the Company or ARA or any other Person on behalf of the Company or
ARA, has directly or indirectly (a) made any contribution, gift, bribe, rebate,
payoff, influence payment, kickback, or other payment to any Person, private or
public, regardless of form, whether in money, property, or services (i) to
obtain favorable treatment in securing business, (ii) to pay for favorable
treatment for business secured, or (iii) to obtain special concessions or for
special concessions already obtained, for or in respect of the Company or ARA,
(b) established or maintained any fund or asset that has not been recorded in
the books and records of the Company of ARA.

                  (v) CUSTOMERS AND SUPPLIERS. Section 3.2V of the Disclosure
Schedule sets forth a true and correct list of (a) the names and addresses of
the 15 largest customers of ARA in terms of sales during each of the two fiscal
years ended June 26, 1998 and 1997 and the seven months ended January 22, 1999,
setting forth the total sales to each such customer during such period and (b)
the names and addresses of the 10 largest suppliers of ARA in terms of purchases
during each of the fiscal years ended June 26, 1998 and 1997 and the seven
months ended January 22, 1999, setting forth for each such supplier the total
purchases from each such supplier during such period. Except as set forth on
Section 3.2V of the Disclosure Schedule, neither the Company nor ARA has
received notice from any such customers or suppliers to the effect that there
will be any price increases in ARA's inputs or price decreases in ARA's outputs.
There has 


                                       32


not been any material adverse change in the business relationship of the Company
with any customer or supplier named on Section 3.2V of the Disclosure Schedule
since June 26, 1998.

                  (w) YEAR 2000 ISSUES. The Company and its Subsidiaries have
developed a plan which, if successfully implemented, will to their knowledge
enable all of their computer systems to process and provide accurate results
using data having date ranges spanning the twentieth and twenty-first centuries.
Without limiting the foregoing, if successfully implemented such plan will to
the knowledge of the Company and its Subsidiaries, cause such computer systems
to (i) manage and manipulate data abnormalities related to such dates; (ii)
manage and manipulate data involving all dates from such centuries without
inaccurate results related to such dates; and (iii) have user interfaces and
data fields formatted to distinguish between dates from the twentieth and
twenty-first centuries. The Company and its Subsidiaries are in the process of
implementing such plan and believe that it can be fully implemented by December
31, 1999 at costs no greater than the costs and reserves relating to "year 2000
issues" shown in the Financial Statements. In addition, the Company and its
Subsidiaries have inquired of all of their material software and hardware
systems vendors and suppliers as to whether such vendors' and suppliers' have
the systems and software necessary to address and accommodate "year 2000
issues", and as to whether such vendors and suppliers computer systems have been
tested and are fully capable of providing accurate results using data having
date ranges spanning the twentieth and twenty-first centuries and, except as set
forth on Section 3.2W of the Disclosure Schedule, each such vendor and supplier
has confirmed the foregoing.

                  (x) REORGANIZATIONS. All reorganizations, restructurings,
mergers, liquidations and dissolutions involving or relating to the Company, ARA
or any former parent corporation of the Company or ARA, (including, without
limitation, Certified Holding Corporation) (collectively, the "FORMER ENTITIES")
complied with all applicable Laws and the organizational documents of such
entities. There are no Liabilities of Certified Holding Corporation that are not
related to the business or properties of the Company or ARA which could
reasonably be expected to be asserted against the Company or ARA. There are no
continuing obligations or liabilities to the Company or ARA in connection with

commercially reasonable efforts to obtain all (and will immediately prepare all
registrations, filings and applications, requests and notices preliminary to
all) Approvals and Permits that may be necessary or which may be reasonably
requested by Buyer to consummate the transactions contemplated by this
Agreement; provided that nothing contained herein shall require either Buyer or
the Company or any of their Affiliates to sell, transfer, divest or otherwise
dispose of any of its respective business, assets or properties in connection
with this Agreement or any other transactions contemplated hereby. Buyer shall
pay all fees required in connection with any filing required under the
Hart-Scott-Rodino Act.

                  (b) To the extent that Buyer determines in its reasonable
discretion the Approval of a third party with respect to any Material Contract
is required or desirable in connection with the transactions contemplated by
this Agreement, the Company shall use commercially reasonable efforts to obtain
such Approval prior to the Closing Date and in the event that any such Approval
is not obtained, the Company shall reasonably cooperate with Buyer in an effort
to obtain for Buyer the benefits of each such Material Contract. The parties
hereto agree not to take any unreasonable action that will have the effect of
delaying, impairing or impeding the receipt of any Approval or Permit.

                  SECTION 4.3 INVESTIGATION BY BUYER. Subject to applicable
Laws, the Company shall cause ARA to authorize and permit Buyer and its
representatives (which term shall be deemed to include its independent
accountants and counsel and representatives of prospective financing
institutions of Buyer) to have reasonable access during normal business hours,
at the expense of Buyer, under the supervision of the Company or ARA, upon
reasonable notice and in such manner as will not unreasonably interfere with the
conduct of their respective businesses and as will maintain the confidentiality
of this Agreement and the transactions contemplated hereby, to all of the
Company's and ARA's properties, books, records, operating instructions and
procedures, Tax Returns and all other information with respect to the Business
as Buyer may from time to time reasonably request, and to make copies of such
books, records and other documents and to discuss its business with such other
Persons, including its directors, officers, employees, accountants, counsel,
suppliers, customers, and creditors, as are necessary or appropriate for the
purposes of familiarizing itself with the Business, obtaining any necessary
Approvals of or Permits for the transactions contemplated by this Agreement and
conducting an evaluation of the organization and Business of the Company. 


                                       35


                  SECTION 4.4 PUBLICITY. Until the Closing Date, all parties
hereto shall coordinate all publicity relating to the transactions contemplated
by this Agreement and no party shall issue any press release, publicity
statement or other public notice relating to this Agreement, or the transactions
contemplated by this Agreement, without obtaining the prior consent of all
parties hereto, except to the extent required by applicable Law.

                  SECTION 4.5 SHAREHOLDERS' CONSENT. The Board of Directors of
the Company shall, in accordance with applicable Law, either (i) duly call, give
notice of, convene and hold a special meeting of the shareholders of the Company
or (ii) circulate a written consent of shareholders (in form and substance
satisfactory to Buyer and which complies with all applicable Laws and the
Company's Articles and Incorporation and Bylaws) in lieu of a meeting as soon as
practicable for the purpose of considering and taking action upon this
Agreement. The Company shall take all appropriate action in accordance with all
applicable Laws and the Company's Article of Incorporation and Bylaws (a) to
obtain consent of all its stockholders with respect to the Merger and this
Agreement and (b) to assure the sale of its stockholders' shares of ZMP Common
Stock according to the Voting Agreements.

                  SECTION 4.6 NOTIFICATION OF CERTAIN MATTERS. The Company shall
give prompt notice to Buyer, and Buyer shall give prompt notice to the Company,
of (i) the occurrence, or failure to occur, of any event or fact that would be
likely to cause any representation or warranty made by such party contained in
this Agreement to be untrue in any material respect at any time from the date of
this Agreement to the Closing Date, (ii) any failure of Buyer, Acquisition or
the Company, as the case may be, to comply with or satisfy, in any material
respect, any covenant, condition or agreement to be complied with or satisfied
by it under this Agreement, and (iii) any fact, condition, event or occurrence
that would be likely to prevent any condition to the obligations of the parties
set forth in Article V to be satisfied. Such notice shall provide a reasonably
detailed description of the relevant circumstances and shall include the amount
which the party providing the notice believes, based on the facts actually known
by it, would be payable by the other party pursuant to the indemnification
provides hereof. No such notification shall affect the representations or
warranties of the parties or the conditions to their respective obligations
hereunder.

                  SECTION 4.7 PREPARATION OF TAX RETURNS FOR PRE-CLOSING
PERIODS. The Shareholders' Representative shall prepare and timely file, or
cause to be prepared and timely filed, all Tax Returns required to be filed by
the Company and ARA for any Pre-Closing Period. In the case of any Tax Return of
the Company or ARA for any Pre-Closing Period, Buyer shall (i) cause an officer
of the Company or ARA, as the case may be, to sign such Tax Return, or (ii) duly
and lawfully appoint a Person designated by the Shareholders' Representative as
an officer of the Company or ARA, as the case may be, for purposes of signing
such Tax Return. Shareholders' Representative shall provide to Buyer a copy of
any Tax Return for a Pre-Closing Period no later than 30 days before the due
date (including extensions) for filing such Tax Return for Buyer's review and
consent, which consent shall not unreasonably be withheld (provided, however,
that any position consistent with past practice shall be reasonable for these
purposes).

                  SECTION 4.8 PREPARATION OF TAX RETURNS FOR STRADDLE PERIODS.

                  (a) Buyer shall prepare and timely file, or cause to be
prepared and timely filed, all Tax Returns required to be filed by the Company
and ARA for any Straddle Period. 


                                       36


With respect to each Tax Return filed with respect to a Straddle Period, Buyer
will provide the Shareholders' Representative with a statement (each, a
"Straddle Period Statement") setting forth (i) Buyer's calculation of the Tax
liability of the Company and ARA allocable to the Deemed Pre-Closing Period (the
"Straddle Period Liability"), and (ii) a copy of the Tax Return to be filed with
respect to such Straddle Period. Buyer shall deliver such Straddle Period
Statement to the Shareholders' Representative no later than 30 days before the
due date (including extensions) for filing such Tax Return. The term "Straddle
Period" means any taxable period of the Company or ARA that begins before the
Closing Date and ends after the Closing Date. Items of income, gain, loss,
deduction, and credit for any Straddle Period attributable to the period of time
on or before the Closing Date shall be allocated to a deemed Pre-Closing Period
that ends on the Closing Date (the "Deemed Pre-Closing Period") using an interim
closing-of-the-books method, assuming that the Deemed Pre-Closing Period ended
as of the close of business on the Closing Date. In the case of any Taxes that
are imposed on a periodic basis (other than Taxes based upon or related to
income or receipts), and are payable for a Straddle Period, the portion of such
Tax which relates to the Deemed Pre-Closing period shall be deemed to be the
amount of such Tax for the entire taxable period multiplied by a fraction the
numerator of which is the number of days in the Deemed Pre-Closing Period and
the denominator of which is the number of days in the entire taxable period.

                  (b) Within 20 days of receipt of such Straddle Period
Statement, the Shareholders' Representative shall, in a written notice to the
Buyer, either accept the Straddle Period Statement or describe in reasonable
detail any proposed adjustment to any item of income, gain, loss, deduction, or
credit on the Straddle Period Statement. Buyer and the Shareholders'
Representative shall negotiate in good faith to resolve any disputes over any
proposed adjustments to the Straddle Period Statement, provided that if any such
dispute is not resolved within 10 days after the Buyer's receipt of the proposed
adjustments, Buyer and the Shareholders' Representative shall jointly engage
Arthur Andersen LLP or such other mutually acceptable national independent
public accounting firm ("Tax Arbitrator") to resolve such dispute, which
resolution shall be final and binding upon the parties, and not subject to
review or challenge of any kind. The amount of the Straddle Period Liability
shall be determined based on (i) the Straddle Period Statement prepared by the
Buyer, if the Shareholders' Representative proposes no adjustment or proposes an
adjustment but no resolution of the issue is reached between the Shareholders'
Representative and the Buyer before the due date (including extensions) for
filing the relevant Tax Return, or (ii) the Straddle Period Statement as finally
resolved between Shareholders' Representative and the Buyer, if the
Shareholders' Representative proposes an adjustment and the Shareholders'
Representative and the Buyer reach a resolution, or the Tax Arbitrator reaches a
resolution, of the proposed adjustment before the due date (including
extensions) for filing such relevant Tax Return. If any final resolution of the
proposed adjustment reached after the filing of the relevant Tax Return differs
from the Straddle Period Statement filed, then Buyer shall file an amended Tax
Return for such Straddle Period in accordance with the determination of the Tax
Arbitrator. Any fees and expenses related to the engagement of the Tax
Arbitrator shall be borne equally by Buyer, on one hand, and the Selling
Shareholders through a payment out of the Escrow Account on the other. Buyer and
the Shareholders' Representative will jointly instruct the Escrow Agent, in
writing, to make any such payment.


                                       37


                  SECTION 4.9 TAX CONTROVERSIES.

                  (a) The Shareholders' Representative shall have the right, at
the expense of the Selling Shareholders, to control, manage, and be responsible
for any audit, contest, claim, proceeding or inquiry with respect to Taxes, or
items of income, gain, loss, deduction, and credit of, the Company or ARA (a
"Tax Controversy") for any Pre-Closing Period or Straddle Period, and shall have
the right to settle or contest in their discretion any such Tax Controversy;
provided, however, that if the Tax Controversy reasonably could be expected to
affect the Company's or ARA's liability for Tax in any taxable period ending
after the Closing Date (i) Buyer shall have the right to attend and participate
in, at its own expense, any such Tax Controversy controlled by the Shareholders'
Representative, including the right to review in advance and comment upon all
submissions made in the course of such Tax Controversy, and to be present at all
conferences, meetings or proceedings with any taxing authority, and all
appearances before any court, and (ii) no settlement or any disposition of any
such Tax Controversy shall be made without Buyer's prior written consent, which
shall not be unreasonably withheld.

                  (b) Buyer shall have the right, at its own expense, to
control, manage, and be responsible for any Tax Controversy for any taxable
period ending after the Closing Date (other than Straddle Periods), and shall
have the right settle or contest in their discretion any Tax Controversy;
provided, however, that if the Tax Controversy reasonably could be expected to
affect the Company's or ARA's liability for Tax in any Pre-Closing Period (i)
the Shareholders' Representative shall have the right to attend and participate
in, at the expense of the Selling Shareholders, any such Tax Controversy
controlled by the Buyer, including the right to review in advance and comment
upon all submissions made in the course of such Tax Controversy, and to be
present at all conferences, meetings or proceedings with any taxing authority,
and all appearances before any court, and (ii) no settlement or any disposition
of any such Tax Controversy shall be made without the Shareholders'
Representative's prior written consent, which shall not be unreasonably
withheld.

                  (c) Neither the Escrow Account nor any party hereto shall be
liable for any Tax indemnification if the party to be indemnified did not comply
with the procedures of this Agreement relating to Taxes, but only to the extent
the indemnifying party has been prejudiced by such non-compliance.

                  SECTION 4.10 COOPERATION. After the Closing Date, the
Shareholders' Representative and Buyer will cooperate fully, and will cause
their respective Affiliates to cooperate fully, and will provide assistance as
may reasonably be requested, and cause their respective Affiliates to provide
assistance as may reasonably be requested, in connection with the preparation of
any Tax Return, the conduct of any audit or the defense of any litigation or
other proceeding with respect to any Tax liability of the Company or ARA for any
taxable period and shall retain, or shall cause to be retained, until the
expiration of all applicable statutes of limitation, any records or information
that may be relevant to any such Tax Return or audit.

                  SECTION 4.11 ACCESS TO RECORDS AND INFORMATION. Buyer shall
provide the Shareholders' Representative, and the Shareholders' Representative
shall provide Buyer, with the right, at reasonable times and upon reasonable
notice, to have access to, and to copy and use, 


                                       38

taxable period for which Buyer or the Shareholders' Representative, as the case
may be, is charged with filing responsibility for Tax Returns under this
Agreement or otherwise in connection with the preparation of any Tax Returns,
the conduct of any audits, the defense of any litigation with respect to any Tax
liability, the filing of any claim for a refund of Tax or allowance of any Tax
credit or any judicial or administrative proceedings relating to liability for
Taxes.

                  SECTION 4.12 TAX POSITIONS. Buyer shall not, and shall not
permit the Company or ARA to, unless required by Law (i) make or change any Tax
election, or amend any Tax Return or take any Tax position on any Tax Return, or
(ii) take any action or omit to take any action that in any such case results in
any increased Tax liability of the Company or ARA with respect to any
Pre-Closing Period or any increased Straddle Period Liability.

                  SECTION 4.13 INCOME TAX LIABILITY AND REFUNDS. Any amount of
income Taxes shown as due on any Tax Return for any Pre-Closing Period shall be
timely paid out of the Escrow Account and is hereinafter referred to as a
"Declared Pre-Closing Income Tax Liability." Any income Tax refund due in
respect of any Pre-Closing Periods or Deemed Pre-Closing Periods shall be paid
to the Shareholders' Representative for distribution to the Selling Shareholders
in proportion to their Applicable Percentages. Buyer shall, or shall cause the
Company to, file an amended return or claim for any such refund as requested by
the Shareholders' Representative.

                  SECTION 4.14 NO SOLICITATION OR NEGOTIATION. Between the date
of this Agreement and the earlier of (x) the Closing and (y) the termination of
this Agreement, none of the Company or ARA or any of their respective

in any such notice to the Buyer, indicate in reasonable detail the identity of

confidentiality or standstill agreement to which the Company or ARA is a party.

                  SECTION 4.15 NOVATION AGREEMENTS. The Company shall use its
commercially reasonable efforts to satisfy all conditions to obtaining novation
agreements with 




                                       39

stockholders agreements, proxies or other similar agreements listed on Section
3.2B of the Disclosure Schedule (including, without limitation, the Voting
Agreements) shall have been terminated, in each case, to the reasonable
satisfaction of Buyer; provided, however, that this condition shall be satisfied
even if up to two holders of Dissenting Shares fail to agree to a termination of
the Stockholder Agreement.

                  (o) Approvals. All payments to be made to employees or former
employees pursuant to the Success Bonuses shall have been approved in accordance

"parachute payment" under Code Section 280G.

                  SECTION 5.3 CONDITIONS TO OBLIGATIONS OF THE COMPANY. The

material respects as of such date). Buyer and Acquisition shall have in all
material respects performed all obligations and complied with all covenants and
conditions required by this Agreement to be performed or complied with by them
at or prior to the Closing Date.

                  (b) CERTIFICATE. Buyer and Acquisition shall have delivered to

                                   ARTICLE VI

                                   TERMINATION

                  SECTION 6.1 TERMINATION. This Agreement may be terminated by:

                  (a) Buyer (who shall pay to the Company $250,000 upon exercise
of the right to terminate contained in this Section 6.1(a)) at the time the
Closing would otherwise have occurred if (i) all of the conditions set forth in
Section 5.1 and Section 5.2 shall have been satisfied other than those
conditions that are contemplated to be satisfied at the Closing and (ii) the
funds committed in the BT Commitment Letter are unavailable.

                  (b) Mutual consent in writing of the Company, Buyer and
Acquisition;

                  (c) The Company or Buyer at any time after May 15, 1999 (the
"Termination Date") if the Closing shall not have occurred by such date;
provided, that the right to terminate this Agreement under this Section 6.1(c)
shall not be available to any party whose breach of any representation or
warranty or failure to fulfill any obligation under this Agreement has been the
cause of, or resulted in, the failure of the Closing to occur by such date.

                  (d) Buyer by written notice to the Company if any event occurs
or condition exists (and cannot be cured on or prior to the Termination Date by
the parties' reasonable best efforts) which would render impossible the
satisfaction of one or more conditions to the obligations of Buyer to consummate
the transactions contemplated by this Agreement as set forth in Section 5.1 or
5.2.

                  (e) The Company by written notice to Buyer if any event occurs
or condition exists (and cannot be cured on or prior to the Termination Date by
the parties' reasonable best efforts) which would render impossible the
satisfaction of one or more conditions to the obligation of the Company to
consummate the transactions contemplated by this Agreement as set forth in
Section 5.1 or 5.3.

                  SECTION 6.2 EFFECTS OF TERMINATION. In the event of the
termination of this Agreement pursuant to Section 6.1, this Agreement shall
thereafter become void and have no future effect, and no party hereto shall have
any liability to the other parties hereto or their respective stockholders or
directors or officers in respect thereof; provided that the obligations of the
parties contained in Sections 9.8 and 9.12 shall survive any such termination;
and provided further that notwithstanding anything to the contrary contained
herein, a termination under Section 6.1 shall not relieve any party of any
liability for a willful breach of or for any willful 


                                       43


misrepresentation under this Agreement or be deemed to constitute a waiver of
any available remedy (including specific performance if available) for any such
breach or misrepresentation.

                                   ARTICLE VII

                                    INDEMNITY

                  SECTION 7.1 INDEMNIFICATION OF BUYER. From and after the
Closing, Buyer, Surviving Corporation and their respective directors, officers,
employees, Affiliates, agents, advisors, representatives and assigns ("Buyer
Indemnitees") shall be indemnified and held harmless by the holders of ZMP
Common Stock on the date hereof out of funds in the Escrow Account and/or the
Glendale Escrow Account, as the case may be, available therefor, from and
against any and all Losses of any such Person, directly or indirectly, as a
result of, or based upon or arising from (1) any untruth or inaccuracy of any of
the representations or warranties (except to the extent related to Taxes) made
by the Company in Section 3.2 of this Agreement or any of the agreements or
covenants (except to the extent related to Taxes) made by the Company in Article
IV of this Agreement, (2) without duplication, (x) any breach of the covenant to
pay any Declared Pre-Closing Income Tax Liability, (y) all Taxes of the Company
or ARA relating to Pre-Closing Periods and (z) any Straddle Period Liability
(collectively "Tax Losses"), (3) any amounts described in Sections 2.8(a)(iii)
and (iv) hereof which are not paid on the Closing Date from the Purchase Price,
(4) Section 1300 Payments and payments required under Section 2.11 in connection
with or as a result of the existence of Dissenting Shares at the Closing if and
to the extent such Losses or payments exceed the Dissenting Share Amount and (5)
any claims or allegations of third parties against any Indemnified Party of any
violation or non-compliance with or pursuant to any Environmental Law at the
Glendale Facility. Indemnification under Section 7.1(1), (2), (3) and (4) shall
be available solely from the Escrow Account as provided herein. Indemnification
under Section 7.1(5) shall be available solely from the Glendale Escrow Account
and the Escrow Account as provided herein.

                  SECTION 7.2 INDEMNIFICATION BY BUYER. From and after the
Closing, Buyer agrees to indemnify and hold harmless each of the Selling
Shareholders and the directors, officers, employees, Affiliates, agents,
advisors, representatives and assigns of each of the Selling Shareholders
("Seller Indemnitees") from and against any and all Losses of any of any such
Person, directly or indirectly, as a result of, or based upon or arising from
any material breach or nonperformance of any of the representations, warranties,
covenants or agreements made by Buyer or Acquisition in or pursuant to this
Agreement.

                  SECTION 7.3 PROCEDURE.

                  (a) Any party seeking indemnification with respect to any Loss
or potential Loss arising from a claim (an "Indemnifiable Claim") asserted by a
third party (including a notice of Tax audit or request to waive or extend a
statute of limitations applicable to any Tax) shall give written notice to the
party required to provide indemnity hereunder (the "Indemnifying Party").
Written notice to the Indemnifying Party of the existence of a third-party
Indemnifiable Claim shall be given by the Indemnified Party within 30 days after
its receipt of a written assertion of liability from the third party, including
in the case of tax matters, written notice of any tax audit that might result in
such a claim. The failure of any Indemnified Party to give 


                                       44


timely notice hereunder shall not affect rights to indemnification hereunder,
except and only to the extent that the Indemnifying Party demonstrates actual
damage caused by such failure.

                  (b) If any claim, demand or liability is asserted by any third
party against any Person entitled to indemnification hereunder (the "Indemnified
Party"), the Indemnifying Party shall defend any actions or proceedings brought
against the Indemnified Party in respect of matters embraced by the indemnity.
If, after 10 business days following a written request by the Indemnified Party
to defend any action or proceeding, the Indemnifying Party neglects to defend
the Indemnified Party, the Indemnified Party may defend, compromise or settle
the claim on behalf of and for the account and risk of the Indemnifying Party,
who shall be bound by the result. In all cases, the party without the right to
control the defense of the Indemnifiable Claim may participate in the defense at
its own expense.

                  (c) Notwithstanding anything in this Section 7.3 to the
contrary except as set forth in Section 7.3(b), neither the Indemnifying Party
nor the Indemnified Party shall, without the written consent of the other Party,
settle or compromise any Indemnifiable Claim or permit a default or consent to
entry of any judgment unless the claimant and such party provide to such other
Party an unqualified release from all liability in respect of the Indemnifiable
Claim. Notwithstanding the foregoing, if a settlement offer solely for money
damages is made by the applicable third party claimant, and the Indemnifying
Party notifies the Indemnified Party in writing of the Indemnifying Party's
willingness to accept the settlement offer and, subject to the limitations of
Sections 7.5 and 7.6, pay the amount called for by such offer, and the
Indemnified Party declines to accept such offer, the Indemnified Party may
continue to contest such Indemnifiable Claim, free of any participation by the
Indemnifying Party, and the amount of any ultimate liability with respect to
such Indemnifiable Claim that the Indemnifying Party has an obligation to pay
hereunder shall be limited to the lesser of (A) the amount of the settlement
offer that the Indemnified Party declined to accept plus the Losses of the
Indemnified Party relating to such Indemnifiable Claim through the date of its
rejection of the settlement offer or (B) the aggregate Losses of the Indemnified
Party with respect to such Indemnifiable Claim. If the Indemnifying Party makes
any payment on any Indemnifiable Claim, the Indemnifying Party shall be
subrogated, to the extent of such payment, to all rights and remedies of the
Indemnified Party to any insurance benefits or other claims of the Indemnified
Party with respect to such Indemnifiable Claim.

                  SECTION 7.4 SURVIVAL.

                  (a) Each of the representations, warranties, covenants and
agreements contained in or made pursuant to this Agreement or any other
Transaction Document shall expire on the first anniversary of the Closing,
except that the representations contained in Section 3.2(q) and the covenants
and agreements contained in clauses (2), (3), (4) and (5) of Section 7.1 shall
survive the Closing and shall terminate on the third anniversary of the Closing
(the period from the date hereof until the date of the termination of the
related representation, warranty, covenant or agreement is referred to herein as
the "Survival Period"). Except with respect to any matter as to which a claim
has been asserted by notice to the other party that is pending or unresolved at
the end of the pertinent Survival Period, the parties intend to shorten the
statute of limitations and agree that no claims or causes of action may be
brought against any of the Selling Shareholders, the Company, Acquisition or
Buyer based upon, directly or indirectly, any of the 


                                       45


representations, warranties, covenants or agreements (including covenants and
agreements to indemnify) contained in or made pursuant to this Agreement or any
other Transaction Document after the expiration of the pertinent Survival Period
or any termination of this Agreement.

                  (b) The indemnifications provided for hereunder shall take
effect upon Closing and shall remain in effect during the relevant Survival
Period. Any matter as to which a claim has been asserted by notice to the other
party that is pending or unresolved at the end of the pertinent Survival Period
shall continue to be covered by this Article VII notwithstanding the expiration
of the Survival Period with respect to such claim or the expiration of any
applicable statute of limitations (which the parties hereby waive) until such
matter is finally terminated or otherwise formally resolved by the parties under
this Agreement or by a court of competent jurisdiction and any amounts payable
hereunder are finally determined and paid. Any written notice delivered by a
party with respect to a claim for indemnification shall set forth with
specificity the basis of the claim and a reasonable estimate of the amount
thereof.

                  SECTION 7.5 LIMITATIONS ON INDEMNIFICATION OF BUYER. In
addition to the other limitations set forth herein, including the limitations
set forth in Sections 7.1 and 7.4, Buyer's right to indemnification pursuant to
this Article VII is subject to the following limitations:

                  (a) No indemnification shall be made unless the aggregate
amount of Losses sustained by Buyer Indemnitees under Sections 7.1(1) and (5)
(such amount, "Buyer Losses") exceeds $250,000 and, in such event,
indemnification shall be made only to the extent Buyer Losses exceed $250,000
(it being understood that any Buyer Losses sustained prior to the expiration of
a Survival Period shall continue to be counted for purposes of this Section
7.5(a) in determining whether Buyer is entitled to indemnification). The
limitation under the first sentence of this Section 7.5(a) shall not apply to
Buyer's right to indemnification pursuant to Section 7.1(2), (3) and (4) (it
being understood that in all such cases, Buyer shall be entitled to seek
indemnity immediately) and any Losses for which the Buyer is indemnified under
such sections shall not count towards determining whether Buyer Losses exceed
$250,000.

                  (b) Notwithstanding anything to the contrary herein, the
parties hereto agree that any amounts payable under or pursuant to this Article
VII (other than pursuant to Section 7.1(5)) to any Buyer Indemnitee or in
respect of any Buyer Losses (including any settlement of any Indemnifiable
Claims in accordance with Section 7.3(c)) will be paid solely out of the Escrow
Account, in accordance with this Agreement and the Escrow Agreement, and none of
the Selling Shareholders will have any obligation to make (or otherwise with
respect to) any such payments other than from the Escrow Account. In addition,
notwithstanding anything to the contrary herein, the parties hereto agree that
any amounts payable or pursuant to Section 7.1(5) to any Buyer Indemnitee or in
respect of Buyer Losses (including any settlement of any Indemnifiable Claims in
accordance with Section 7.3(c)) will be solely out of the Escrow Account and the
Glendale Escrow Account in accordance with this Agreement and the Escrow
Agreement, and none of the Selling Shareholders will have any obligation to make
or otherwise with respect to any such payments other than from the Escrow
Account and the Glendale Escrow Account.


                                       46


                  (c) The amount of any Buyer Losses shall be reduced by any
amount received by Buyer Indemnitees with respect thereto under any insurance
coverage or for any other party alleged to be responsible therefor. Buyer
Indemnitees shall use commercially reasonable efforts to collect any amounts
available under such insurance coverage and from such other party alleged to
have responsibility. If a Buyer Indemnitee receives an amount under insurance
coverage or from such other party with respect to Buyer Losses at any time
subsequent to any indemnification pursuant to this Section 7.5, then such Buyer
Indemnitee shall promptly reimburse the Escrow Account for any payment made,
including expenses incurred, from the Escrow Account in connection with
providing such indemnification up to such amount received by the Buyer
Indemnitee.

                  SECTION 7.6 LIMITATIONS ON INDEMNIFICATION BY BUYER. In
addition to the other limitations set forth herein, including the limitations
set forth in Sections 7.2 and 7.4, Buyer's obligation to indemnify pursuant to
this Article VII is subject to the following limitations:

                  (a) No indemnification shall be made by Buyer unless the
aggregate amount of Losses claimed by Seller Indemnitees under Section 7.2 (such
amount, "Seller Losses") exceeds $250,000 and, in such event, indemnification
shall be made by the Buyer only to the extent Seller Losses exceed $250,000.

                  (b) The amount of any Seller Losses shall be reduced by any
amount received by Seller Indemnitees with respect thereto under any insurance
coverage or for any other party alleged to be responsible therefor. Seller
Indemnitees shall use best efforts to collect any amounts available under such
insurance coverage and from such other party alleged to have responsibility. If
a Seller Indemnitee receives an amount under insurance coverage or from such
other party with respect to Seller Losses at any time subsequent to any
indemnification provided by Buyer pursuant to this Section 7.6, then such Seller
Indemnitee shall promptly reimburse Buyer for any payment made or expense
incurred by Buyer in connection with providing such indemnification up to such
amount received by the Seller Indemnitee.

                  SECTION 7.7 NO SPECULATIVE DAMAGES. Notwithstanding anything
to the contrary elsewhere in this Agreement, no party (or any of its Affiliates)
shall, in any event, be liable to the other party (or any of its Affiliates) for
any speculative damages or remote consequential damages of such other party (or
any of its Affiliates), including loss of speculative future revenue or income,
or loss of business reputation or opportunity relating to the breach or alleged
breach hereof.

                  SECTION 7.8 EXCLUSIVE REMEDY. The remedies provided for in
this Article VII, as limited by the provisions of this Article VII, shall
constitute the sole and exclusive remedy for any post-Closing claims made for
breach of this Agreement or otherwise in connection with the transactions
contemplated hereby; provided that nothing herein shall extinguish or limit any
claim based on fraud.

                  SECTION 7.9 ADJUSTMENT TO MERGER CONSIDERATION. Any payment
pursuant to this Article VII shall be treated for Tax purposes as an adjustment
to the Merger Consideration.


                                       47


                  SECTION 7.10 TAX ADJUSTMENTS. Any amounts payable by the
Indemnifying Party to or on behalf of an Indemnified Party in respect of a Loss
shall be adjusted as follows. The Indemnified Party shall reimburse the
Indemnifying Party an amount equal to the present value amount of the net
reduction in any year in the liability for Taxes of the Indemnified Party or any
member of a consolidated or combined tax group of which the Indemnified Party
is, or was at any time, part, which reduction will be realized (either through
the reduction of a Tax liability or the increase of a Tax loss or credit) with
respect to any period after the Closing Date and which reduction would not have
been realized but for the amounts paid (or any audit adjustment or deficiency
with respect thereto, if applicable) in respect of a Loss for which the
Indemnified Party is indemnified by the Indemnifying Party pursuant to this
Agreement, or amounts paid by the Indemnified Party pursuant to this paragraph
(a "Net Tax Benefit"). The present value amount of the Net Tax Benefit shall be
determined by: (i) using a discount rate equal to the mid-term applicable
federal rate (under Section 1274(d) of the Code) in effect on the date by which
the payment subject to the Net Tax Benefit adjustment is due, (ii) discounting
back to the date by which the payment subject to the Net Tax Benefit adjustment
is due and (iii) using reasonable assumptions regarding the date (or dates) on
which such Net Tax Benefit will be realized, which assumptions must be verified
by an independent certified public accountant chosen by the Indemnifying Party
if requested by the Indemnifying Party. Each party agrees to provide the other
party or their designated representatives with assistance and such documents and
records reasonably requested by them that are relevant to their ability to
determine when a Net Tax Benefit will be realized, including but not limited to
copies of Tax Returns, estimated tax payments, schedules, and related supporting
documents. In the event the parties are unable to agree on the amount, the
parties shall engage the Tax Arbitrator to resolve the matter, whose decision
shall be final and binding upon the parties and not subject to review or
challenge of any kind.


                                  ARTICLE VIII

                                     ESCROW

                  SECTION 8.1 ASSERTION OF INDEMNIFIABLE CLAIMS. From time to
time during the pertinent Survival Period, Buyer (on its own behalf or on behalf
of the Company) or its successors or assigns may assert a claim that it or a
Buyer Indemnitee is entitled to indemnification pursuant to Section 7.1 (any
such claim for indemnification under Section 7.1(1), (2), (3) or (4), a "Claim"
and any such claim for indemnification under Section 7.1(5), a "Glendale Claim")
and demand satisfaction thereof out of the Escrow Account and/or the Glendale
Escrow Account by sending a written notice to the Shareholders' Representative.
If the Shareholders' Representative shall receive such notice from Buyer before
any termination of the pertinent Survival Period, the notice shall be deemed to
represent a pending Claim (or Claims) or Glendale Claim (or Claims), as the case
may be. Any such notice of a Claim or a Glendale Claim shall be effective only
if the Shareholders' Representative receives a certificate from an executive
officer of Buyer to the effect that the Buyer Indemnitees are entitled to
indemnification therefor pursuant to Article VII, along with a reasonable
description of the Claim or Glendale Claim, the relevant representations,
warranties, covenants or agreements for the breach of which indemnification is
being sought, the dollar amount thereof, copies of any documentation related
thereto and any other information reasonably requested by Shareholders'
Representative to support such Claim or Glendale Claim.


                                       48


                  SECTION 8.2 RESOLUTION OF CLAIMS; PAYMENTS. (a) Upon the final
resolution of any Claim and a final determination that any amount is owing in
respect thereof to Buyer, or, in the case of any Claim in respect of any Tax
Losses relating to any Straddle Period Liability or any payment of any Declared
Pre-Closing Income Tax Liability, immediately prior to the due date (including
extensions) for filing the relevant Tax Return, Buyer and the Shareholders'
Representative shall jointly instruct Escrow Agent, in writing, to make the
pertinent payment to Buyer or the relevant taxing authority. Upon the final
resolution of all claims relating to Dissenting Shares, Buyer and the
Shareholders' Representative shall jointly instruct the Escrow Agent, in
writing, to pay the excess of $200,000 over the amount payable to Buyer or the
Surviving Corporation in respect of such claims, if any, to the Selling
Shareholders in proportion to their respective Applicable Percentages. Upon the
final resolution of (x) between the first and the third anniversaries of the
Closing, any Claim other than a Claim relating to a purported untruth or
inaccuracy of the representation contained in Section 3.2(q) or to
indemnification under clauses (2), (3), (4) or (5) of Section 7.1 and (y)
thereafter, any claim, Buyer and the Shareholders' Representative shall jointly
instruct the Escrow Agent, in writing, to pay the excess of the amount reserved
in respect of such Claim over the amount payable to Buyer in respect thereof, if
any, to the Selling Shareholders in proportion to their respective Applicable
Percentages; provided if the aggregate amount in the Escrow Account would be
less than the sum of (1) $1,500,000 and (2) an amount by which $200,000 exceeds
any payments made (A) to Buyer Indemnitees in respect of indemnification under
clause (4) of Section 7.1 plus (B) any payments made to the Shareholders'
Representative under the second sentence of this Section 8.2 after any such
payment is proposed to be made such payment shall be reduced to the extent
necessary to avoid such result.

                  (b) Upon the final resolution of any Glendale Claim, Buyer and
Shareholders' Representative shall jointly instruct Escrow Agent, in writing, to
make the pertinent payment to Buyer from the Glendale Escrow Account and/or the
Escrow Account, as applicable.

                  SECTION 8.3 PERIODIC PAYMENTS FROM THE ESCROW ACCOUNTS.

                  (a) Buyer and the Shareholders' Representative shall, ten days
following the first anniversary of the Closing, jointly instruct Escrow Agent,
in writing, to pay to the Selling Shareholders in proportion to their respective
Applicable Percentages an amount, if any, equal to $1,500,000 minus the sum of
(w) the amount of all pending Claims, (x) the amount of all prior payments out
of the Escrow Account in respect of Claims other than any such pending Claims or
payments in respect of Claims relating to Dissenting Shares, (y) the amount of
all payments made to Buyer pursuant to Sections 2.10 and 2.12 and (z) to the
extent that Buyer has delivered a statement pursuant to Section 2.12 requesting
payment in accordance therewith, the amount of such payment so requested.

                  (b) If on or at any time after the third anniversary of the
Closing the amount on deposit in the Escrow Account exceeds the amount of all
then pending Claims, Buyer and the Shareholders' Representative shall jointly
instruct the Escrow Agent, in writing, to pay to the Selling Shareholders in
proportion to their respective Applicable Percentages, the amount of such
excess.


                                       49


                  (c) If on or at anytime after the date that is 18 months after
the Closing, the amount on deposit in the Glendale Escrow Account exceeds the
amount of all then pending Glendale Claims to be paid from the Glendale Escrow
Account, Buyer and Shareholders' Representative shall jointly instruct the
Escrow Agent, in writing, to pay to the Selling Shareholders in proportion to
their Applicable Percentages, the amount of such excess.

                  (d) No less frequently than quarterly, Buyer and the
Shareholders' Representative shall jointly instruct the Escrow Agent, in
writing, to pay to the Selling Shareholders in proportion to their respective
Applicable Percentages, 50% of the earnings on amounts on deposit in the Escrow
Account, provided that prior to any such payments all expenses due and owing to
the Escrow Agent shall be paid in full.

                  (e) If the Shareholders' Representative so requests, any
instruction to the Escrow Agent to pay any amount to the Selling Shareholders
may state that a portion thereof should instead be paid to the Shareholders'
Representative to defray the Shareholders' Representative's past or future
out-of-pocket expenses in carrying out its responsibilities hereunder.

                  (f) Whenever the Shareholders Representative and/or the
Selling Shareholders shall be entitled to receive a distribution from the Escrow
Account or the Glendale Escrow Account (other than a distribution of current
earnings) the Escrow Agent shall first pay out of such distribution the amount
of the incremental Success Bonuses due to the persons entitled to receive
Success Bonuses as a result of any such proposed distribution and no amount
shall be paid to any Selling Shareholder unless and until all such incremental
Success Bonuses are so paid.

                  SECTION 8.4 TERMINATION OF THE ESCROW ACCOUNT. When all
pending Claims have been finally resolved and paid as set forth in Section 8.2,
the escrow with respect to the Escrow Account shall terminate; provided,
however, that if at any time prior thereto the amount on deposit in the Escrow
Account shall equal zero, then the escrow shall terminate at such earlier time.

                                   ARTICLE IX

                                  MISCELLANEOUS

                  SECTION 9.1 AMENDMENTS; WAIVERS. This Agreement and any
schedule or exhibit attached hereto may be amended only by agreement in writing
of all parties.

                  SECTION 9.2 SCHEDULES; EXHIBITS; INTEGRATION.

                  (a) Each schedule and exhibit delivered pursuant to the terms
of this Agreement shall be in writing and shall constitute a part of this
Agreement, although schedules need not be attached to each copy of this
Agreement. This Agreement, together with such schedules and exhibits,
constitutes the entire agreement among the parties pertaining to the subject
matter hereof and supersedes all prior agreements and understandings of the
parties in connection therewith.


                                       50


                  (b) Any fact or item which is clearly disclosed on any
schedule or exhibit delivered pursuant to this Agreement or in the financial
statements delivered pursuant to this Agreement in such a way as to make its
relevance or applicability to a representation or representations made elsewhere
in this Agreement or to the information called for by another schedule or other
schedules (or exhibit or other exhibits) to this Agreement reasonably apparent
shall be deemed to be an exception to such representation or representations or
to be disclosed on such other schedule or schedules (or exhibit or exhibits), as
the case may be, notwithstanding the omission of a reference or cross-reference
thereto.

                  SECTION 9.3 FURTHER ASSURANCES. The parties hereto each agree
to execute, make, acknowledge, and deliver such instruments, agreements and
other documents as may be reasonably required to effectuate the purposes of this
Agreement and to consummate the transactions contemplated hereby.

                  SECTION 9.4 GOVERNING LAW. This Agreement, the legal relations
between the parties and any Action, whether contractual or non-contractual,
instituted by any party with respect to matters arising under or growing out of
or in connection with or in respect of this Agreement shall be governed by and
construed in accordance with the Laws of the State of California applicable to
contracts made and performed in such State and without regard to conflicts of
law doctrines, except to the extent that certain matters are preempted by
federal law. Each party hereby irrevocably submits to and accepts for itself and
its properties, generally and unconditionally, the exclusive jurisdiction of and
service of process pursuant to the Laws of the State of California and the rules
of its courts, waives any defense of forum non conveniens and agrees to be bound
by any judgment rendered thereby arising under or out of in respect of or in
connection with this Agreement or any related document or obligation. Each party
further irrevocably designates and appoints the individual identified in or
pursuant to Section 9.11 hereof to receive notices on its behalf, as its agent
to receive on its behalf service of all process in any such Action before any
body, such service being hereby acknowledged to be effective and binding service
in every respect. A copy of any such process so served shall be mailed by
registered mail to each party at its address provided in Section 9.11; provided
that, unless otherwise provided by applicable Law, any failure to mail such copy
shall not affect the validity of the service of such process. If any agent so
appointed refuses to accept service, the designating party hereby agrees that
service of process sufficient for personal jurisdiction in any action against it
in the applicable jurisdiction may be made by registered or certified mail,
return receipt requested, to its address provided in Section 9.11. Each party
hereby acknowledges that such service shall be effective and binding in every
respect. Nothing herein shall affect the right to serve process in any other
manner permitted by Law or shall limit the right of any party to bring any
action or proceeding against the other party in any other jurisdiction.

                  SECTION 9.5 NO ASSIGNMENT. Neither this Agreement nor any
rights or obligations under it are assignable.

                  SECTION 9.6 HEADINGS. The descriptive headings of the
Articles, Sections and subsections of this Agreement are for convenience only
and do not constitute a part of this Agreement.


                                       51


                  SECTION 9.7 COUNTERPARTS. This Agreement and any amendment
hereto or any other agreement (or document) delivered pursuant hereto may be
executed in one or more counterparts and by different parties in separate
counterparts. All of such counterparts shall constitute one and the same
agreement (or other document) and shall become effective (unless otherwise
provided therein) when one or more counterparts have been signed by each party
and delivered to the other party.

                  SECTION 9.8 CONFIDENTIALITY. All information disclosed by any
party (or its representatives) whether before or after the date hereof, in
connection with the transactions contemplated by, or the discussions and
negotiations preceding, this Agreement to any other party (or its
representatives) shall be kept confidential by such other party and its
representatives and shall not be used by any Persons other than as contemplated
by this Agreement, except to the extent that such information (i) was known by
the recipient when received, (ii) is or hereafter becomes lawfully obtainable
from other sources, (iii) is necessary or appropriate to disclose to a
Governmental Entity having jurisdiction over the parties, (iv) as may otherwise
be required by Law or (v) to the extent such duty as to confidentiality is
waived in writing by the other party. The obligations in this Section 9.8 shall
survive until the fifth anniversary of the date hereof. If this Agreement is
terminated, each party shall use all reasonable efforts to return upon written
request from the other party all documents (and reproductions thereof) received
by it or its representatives from such other party (and, in the case of
reproductions, all such reproductions made by the receiving party) that include
information not within the exceptions contained in the first sentence of this
Section 9.8, unless the recipients provide assurances reasonably satisfactory to
the requesting party that such documents have been destroyed.

                  SECTION 9.9 PARTIES IN INTEREST. This Agreement shall be
binding upon and inure to the benefit of each party, and, except as stated in
the next sentence, nothing in this Agreement, express or implied, is intended to

herein or in any other Transaction Document, each of the Selling Shareholders
are intended to be, and are hereby expressly made, third party beneficiaries of
Articles VII and VIII and the Escrow Agreement. Nothing in this Agreement is
intended to relieve or discharge the obligation of any third person to (or to
confer any right of subrogation or action over against) any party to this
Agreement.

                  SECTION 9.10 PERFORMANCE BY SUBSIDIARIES. Each party agrees to
cause its Subsidiaries to comply with any obligations hereunder relating to such
Subsidiaries and to cause its Subsidiaries to take any other action which may be
necessary or reasonably requested by the other party in order to consummate the

                                       53


                  SECTION 9.13 REMEDIES; WAIVER. Except to the extent this
Section 9.13 is inconsistent with any other provision in this Agreement
(including without limitation Section 7.8) or applicable Law, all rights and
remedies existing under this Agreement and any related agreements or documents
are cumulative to and not exclusive of, any rights or remedies otherwise
available. No failure on the part of any party to exercise or delay in
exercising any right hereunder shall be deemed a waiver thereof, nor shall any
single or partial exercise preclude any further or other exercise of such or any
other right.

                  SECTION 9.14 ATTORNEY'S FEES. In the event of any Action by
any party arising under or out of, in connection with or in respect of, this
Agreement, the prevailing party shall be entitled to reasonable attorney's fees,
costs and expenses incurred in such Action, unless a court determines that such
fees, costs and expenses should be allocated in a different manner.

                  SECTION 9.15 KNOWLEDGE CONVENTION. Whenever used in this
Agreement or in any schedule, exhibit, certificate or other documents delivered
to any party pursuant to this Agreement or any other Transaction Document, "to
the knowledge of the Company", "to the best knowledge of the Company" and words
or phrases of similar import shall mean the actual knowledge of the employees
listed on Schedule 9.15 hereto, after due inquiry, which shall be satisfied by
any such employee's consultation with senior management, and (ii) "to the
knowledge of the Buyer", "to the best knowledge of the Buyer" and words or
phrases of similar import shall mean the actual knowledge of the executive
officers of the Buyer, after due inquiry, which shall be satisfied by
consultation with senior management.

                  SECTION 9.16 REPRESENTATION BY COUNSEL; INTERPRETATION. The
Company, Acquisition and Buyer each acknowledge that each party to this
Agreement or any other Transaction Document has been represented by counsel in
connection with this Agreement or such other Transaction Document and the
transactions contemplated hereby or thereby. Accordingly, any rule of Law or any
legal decision that would require interpretation of any claimed ambiguities in
this Agreement or such other Transaction Document against the party that drafted
it has no application and is expressly waived. The provisions of this Agreement
and the other Transaction Documents shall be interpreted in a reasonable manner
to effect the intent of the parties hereto. Whenever the words "include",
"includes" or "including" are used in this Agreement or any other Transaction
Document, they shall be deemed to be followed by the words "without limitation."

                  SECTION 9.17 WAIVER OF JURY TRIAL. Each party waives any right
to a trial by jury in any Action to enforce or defend any right under this
Agreement or any other related document and agrees that any Action shall be
tried before a court and not before a jury.

                  SECTION 9.18 SEVERABILITY. If any provision of this Agreement
is determined to be invalid, illegal or unenforceable by any Governmental
Entity, the remaining provisions of this Agreement to the extent permitted by
Law shall remain in full force and effect, unless doing so would result in an
interpretation of this Agreement which is manifestly unjust.

                  SECTION 9.19 APPOINTMENT OF SHAREHOLDERS' REPRESENTATIVE. At
the Effective Time and without any action on the part of any Person, TCW Special
Placements Fund II, a California limited partnership, will be appointed as the
representative (the "Shareholders' 


                                       54


Representative") of the holders of the ZMP Shares immediately prior to the
Effective Time (and any holder of Dissenting Shares at such time which can later
be treated as ZMP shares as of such time) for the purposes of carrying out the
functions required of the Shareholders' Representative set forth in this
Agreement and the Escrow Agreement. Any action or decision taken by the
Shareholders' Representative shall be binding and conclusive on such holders of
the ZMP Shares, and may be relied upon by Buyer. By accepting the Merger
Consideration, each Selling Shareholder will agree to indemnify and hold
harmless the Shareholders' Representative for any act or failure to act of
Shareholders' Representative taken on behalf of such Person, except for the
Shareholders' Representative's gross negligence or willful misconduct. In the
event that the Shareholders' Representative becomes no longer able to carry out
its functions, a replacement Shareholders' Representative will be appointed if
prior to the Effective Time, by the Board of Directors of the Company, and, if
at or after the Effective Time, by majority vote of the Selling Shareholders
based upon the number of the ZMP Shares held immediately prior to the Effective
Time by each such Person. From time to time the Shareholders' Representative
shall be entitled to withhold from any amounts payable to the Selling
Shareholders such amounts (or estimated amounts) as it deems appropriate to
cover any expenses incurred by or on behalf of any of the Company, the Selling
Shareholders and the Shareholders' Representative related to this Agreement, the
Escrow Agreement or any other Transaction Document.

                  SECTION 9.20 ENTIRE AGREEMENT. This Agreement, the Voting
Agreement and the Escrow Agreement constitute the entire agreement and supersede
all prior agreements and understandings, both written and oral, among the
parties with respect to the subject matter hereof, other than the
Confidentiality Agreement, which shall survive the execution and delivery of
this Agreement.

                          [FORM OF AGREEMENT OF MERGER]

                               AGREEMENT OF MERGER


                  AGREEMENT OF MERGER entered into on ________________, 1999, by
and among ZMP, Inc., a California corporation (the "COMPANY"), TransDigm Inc., a
Delaware corporation ("PARENT"), and ARA Acquisition Corporation, a California
corporation and a wholly-owned subsidiary of Parent ("Acquisition Subsidiary").

                  1. Acquisition Subsidiary, which is a corporation incorporated
           under the General Corporation Law of the State of California, and
           which is sometimes hereinafter referred to as the "DISAPPEARING
           CORPORATION," shall be merged with and into the Company, which is a
           corporation incorporated under the General Corporation Law of the
           State of California, and which is sometimes hereinafter referred to
           as the "SURVIVING CORPORATION."

                  2. The separate existence of the disappearing corporation
shall cease upon the effective date of the merger.

                  3. The surviving corporation shall continue its existence
pursuant to the provisions of the General Corporation Law of the State of
California.

                  4. Upon consummation of the merger, the Articles of
Incorporation of the surviving corporation shall be amended in their entirety to
read as set forth in Exhibit 1 attached hereto.

                  5. Each outstanding share of the common stock of the
disappearing corporation shall, upon the effective date of the merger, be
converted into one share of the common stock of the surviving corporation.

                  6. Each share of the capital stock of the Company issued and
outstanding immediately prior to the effectiveness of the merger (which consists
of 105,435 shares of common stock) shall, upon the effective date of the merger,
be converted into the right to receive $_______ in cash (the "MERGER
CONSIDERATION"). The Merger Consideration is subject to adjustment for payments
of indebtedness for borrowed money, accrued interest thereon, the amount of
success bonuses to be paid to the Company's management, certain transaction
costs and indemnification claims, and for changes in net working capital and the
failure of the Surviving Corporation to enter into a certain contractual
arrangement, as provided in or pursuant to the Agreement and Plan of
Reorganization (the "PLAN OF REORGANIZATION") dated as of [___________], 1999
among Parent, Acquisition Subsidiary, the Company and TCW Special Placements
Fund II, a California limited partnership solely in its capacity as
Shareholders' Representative, and, pursuant to the Plan of Reorganization, a
portion of the Merger Consideration will be held in escrow accounts which will
satisfy adjustments based solely on changes in net working capital, the failure
of the surviving corporation to enter into a certain contractual arrangement and
indemnification claims. A copy of the Plan of Reorganization shall be maintained
at the principal executive offices of the surviving corporation and shall be


                                      A-1


provided without charge to any shareholder of Parent, the disappearing
corporation or the surviving corporation upon written request therefor.

                  7. The merger shall have the effects set forth in Section 1107
of the General Corporation Law of the State of California.

                  8. The disappearing corporation and the surviving corporation
hereby agree that they will cause to be executed and filed and/or recorded any
document or documents prescribed by the laws of the State of California, and
that they will cause to be performed all necessary acts therein and elsewhere to
effectuate the merger.

                  (c) OTHER PROVISIONS. Escrow Agent may sell or present for
                  redemption any obligations so purchased whenever it shall be
                  necessary in order to provide money to meet payments

ruling pending appeal.

                  SECTION 5. NO TRANSFER OF INTEREST IN ESCROW ACCOUNTS. The
Selling Shareholders may assign or transfer, such Person's interest in the
Escrow Account and the Glendale Escrow Account in whole or in part. Except as
set forth in the immediately preceding sentence, no party hereto may transfer or
assign any of its interest herein of obligations hereunder. The Escrow Account
and the Glendale Escrow Account shall remain subject to this Escrow Agreement
and no assignment or transfer by Selling Shareholders shall in any way affect
any rights Buyer may have in the Escrow Account or the Glendale Escrow Account.

                  SECTION 6. METHOD OF PAYMENT. Any payments to be made
hereunder shall be made immediately by wire transfer in immediately available
funds to the account of such party designated in the written instructions
referred to in Section 4.

                  SECTION 7. EXPENSES. Escrow Agent shall be compensated for
services hereunder from the income on the Escrow Funds in accordance with a fee
letter heretofore delivered to Buyer and Selling Shareholders and shall be
reimbursed for its ordinary out-of-pocket expenses including, but not by way of
limitation, the fees and costs of attorneys or agents that it may find necessary
to engage in performance of its duties hereunder and costs arising from the
defense of any suits in which Escrow Agent is named as a defendant in its
capacity as Escrow Agent. If it shall become necessary that Escrow Agent shall
perform extraordinary services, it shall be entitled to reasonable extra
compensation therefor and to reimbursement for reasonable and necessary
extraordinary out-of-pocket expenses unless such extraordinary service or
expense is occasioned by the neglect or breach of this Escrow Agreement by
Escrow Agent.

                  SECTION 8. NOTICES. Any notice or other communication related
hereto must be given in writing and (a) delivered in person, (b) transmitted by
facsimile, (c) mailed by certified or registered mail, postage prepaid, receipt
requested or (d) overnight delivery service, given to the party at its address
stated on the signature pages of this Agreement or at any other address as the
party may specify for this purpose by notice to the other party. Each such
notice or other communication shall be effective (i) if given by
telecommunication, when transmitted to the applicable number and an appropriate
answerback is received, (ii) if given by mail, three days after such
communication is deposited in the mails with first class postage prepaid,
addressed as aforesaid or (iii) if given by any other means, when actually

                  SECTION 9. LIABILITY OF ESCROW AGENT.

                  (a) Escrow Agent's sole liability hereunder shall be to hold
and invest the Escrow Funds and any moneys or other properties received with
respect thereto, to make payments and distributions therefrom in accordance with
the terms of this Escrow Agreement, to distribute information as provided in
Section 4 hereof and otherwise to discharge its obligations hereunder. Escrow
Agent shall not be liable for any act performed in good faith or in reliance on
any document instrument or statement believed by it to be genuine. Escrow Agent
may act upon 



                                      B-3


any notice, certificate, instrument, request, paper or other document believed
by it to be genuine or to have been made, sent, signed, prescribed or presented
by the proper person or persons. It shall be under no obligation to institute or
defend any action, suit or legal proceeding in connection herewith, or to take
any other action likely to involve it in expense unless first indemnified to its
satisfaction by the party or parties who desire that it undertake such action.

                  (b) If any dispute should arise with respect to the payment or
ownership or right of possession of the Escrow Account, or any part thereof, at
any time, that cannot be settled under other provisions hereof, Escrow Agent is
authorized to retain in its possession, without liability to anyone, all or any
part of the Escrow Account or the Glendale Escrow Account or the proceeds from
any sale thereof until such dispute shall have been settled either by mutual
agreement between the parties concerned or until otherwise ordered by a court
having jurisdiction over it. In either case Escrow Agent will not release any
assets in the Escrow Account or the Glendale Escrow Account until Buyer has
exhausted its remedies and has no further right of appeal in the courts;
provided, however, if after the expiration of the Escrow Period, Selling
Shareholders have received a certified order or ruling from a court ordering or
instructing Escrow Agent to distribute all or any portion of the Escrow Funds to
Selling Shareholders, and such order or ruling has not been stayed within 30
days of such order or ruling, pending appeal, Escrow Agent may distribute the
amounts so ordered.

                  (c) Buyer and Selling Shareholders jointly and severally agree
to indemnify and hold harmless Escrow Agent from all losses, costs and expenses
that may be incurred as a result of its involvement in any litigation arising
from the performance of its duties hereunder, provided that such losses costs
and expenses shall not have resulted from any action taken or omitted by Escrow
Agent and for which it shall have been adjudged negligent or engaged in
misconduct or have acted in bad faith or willful disregard of its duties. Escrow
Agent may rely upon any instruction by the Shareholders' Representative as to
the interests of Selling Shareholders. Until it receives written notice of any
change, Escrow Agent shall be entitled to rely on the oral instructions of the
Shareholders' Representative. The Shareholders' Representative shall confirm
such instructions in writing as soon as practicable.

                  SECTION 10. RESIGNATION OR REMOVAL OF ESCROW AGENT.

                  (a) Escrow Agent may resign as such following the giving of
thirty days' prior written notice to the other parties hereto. Similarly, Escrow
Agent may be removed and replaced following the giving of thirty days' prior
written notice to Escrow Agent by all of the other parties hereto. In either
event, the duties of Escrow Agent shall terminate thirty days after the date of
such notice (or as of such earlier date as may be mutually agreeable); and
Escrow Agent shall then deliver the balance of the Escrow Account then in its
possession to a successor Escrow Agent as shall be appointed by the other
parties hereto as evidenced by a written notice filed with Escrow Agent.

                  (b) If the other parties hereto are unable to agree upon a
successor or shall have failed to appoint a successor prior to the expiration of
thirty days following the date of notice of resignation or removal, the
then-acting Escrow Agent may petition any court of competent jurisdiction for
the appointment of a successor Escrow Agent or otherwise appropriate relief, and
any such resulting appointment shall be binding upon all of the parties hereto.

                                      B-4


                  (c) Upon acknowledgement by any successor Escrow Agent of the
receipt of the then remaining balance of Escrow Account, the then-acting Escrow
Agent shall be fully released and relieved of all duties, responsibilities, and
obligations under this Escrow Agreement.

                  SECTION 11. CONTINUANCE OF ESCROW AGREEMENT. This Escrow
Agreement shall be binding upon the parties hereto and their respective
permitted transferees, successors, assigns, legal representatives, heirs and
legatees.

governed by and construed and enforced in accordance with the laws of the State
of California.

                  SECTION 13. INTERPRETATION AND DEFINITIONS. This Escrow

provisions of this Escrow Agreement shall not in any event be construed so as to

                  WHEREAS, Shareholders beneficially own not less than 96,650
shares of Common Stock, par value $.001 per share, of ZMP, Inc., a California
corporation ("ZMP" and the "ZMP COMMON STOCK"). All such shares, together with
all other shares of capital stock of ZMP with respect to which Shareholders have

accordance with the terms of Section 2.

                  WHEREAS, ZMP, Buyer, Acquisition and the Shareholders'
Representative are, simultaneously with the execution hereof, entering into an
Agreement and Plan of Reorganization dated as the date hereof (the "PLAN OF
REORGANIZATION") providing for the merger of Acquisition with and into ZMP (the
"MERGER"). Terms not otherwise defined in this Agreement have the meanings set
forth in the Plan of Reorganization.

                  WHEREAS, The Board of Directors of ZMP has unanimously
approved the Plan of Reorganization and the Merger.

                  WHEREAS, Shareholders and Buyer desire to enter into this
Agreement to provide for, among other things, (1) the obligation of Shareholders
to vote the Subject Shares to approve the Plan of Reorganization and (2) certain
restrictions on (A) the sale or other transfer of the record ownership or the
beneficial ownership, or both, of the Subject Shares by Shareholders and (B) the
acquisition by Shareholders of beneficial ownership of additional shares of
capital stock of ZMP from any person other than ZMP, in each case until the
consummation of the Merger or the termination of the Plan of Reorganization.

                  WHEREAS, Shareholders acknowledge that Buyer and Acquisition
are entering into the Plan of Reorganization in reliance on the representations,
warranties, covenants and other agreements of Shareholders set forth in this
Agreement and would not enter into the Plan of Reorganization if Shareholders
did not enter into this Agreement.

                  NOW, THEREFORE, the parties agree as follows:

                                      C-1

         postponed meeting) of the stockholders of ZMP, however called, or in
         connection with any written consent of the stockholders of ZMP, so that
         all Subject Shares then entitled to vote may be counted for the
         purposes of determining the presence of a quorum at such meetings; and

                  (2) at each such meeting held before the Effective Time and
         with respect to each such written consent, vote (or cause to be voted),
         or deliver a written consent (or cause a consent to be delivered)
         covering, all the Subject Shares to (A) approve the Plan of
         Reorganization and the Merger and any action contemplated thereby or in
         furtherance thereof, (B) disapprove any action or agreement that would
         (or would be reasonably likely to) result in a breach of any covenant,

         under the Plan of Reorganization or this Agreement, (C) approve the
         termination of the Shareholders Agreement of ZMP, dated as of January

         subsidiaries or a reorganization, recapitalization, dissolution or
         liquidation of ZMP or any of its subsidiaries; (3)(a) any change in the
         majority of the board of directors of ZMP; (b) any change in the

         intended, or could reasonably be expected, to impede, interfere with,
         delay, postpone, discourage or materially adversely affect the Merger
         or the transactions contemplated by the Plan of Reorganization or this
         Agreement or the contemplated economic benefits of any of the
         foregoing.

                  (b) STOCK ACQUISITIONS. Until the termination of this
Agreement, Shareholders shall not acquire beneficial or record ownership of any
Equity Securities of ZMP whether acquired of record or beneficially by such
Shareholder in any capacity, whether upon exercise of options, conversion of
convertible securities, purchase, exchange or otherwise, unless such shares are
expressly included within the meaning of "Subject Shares.".

                  (c) NO INCONSISTENT AGREEMENTS. Until the day following the
termination of this Agreement, Shareholders shall not enter into any voting
agreement or grant a proxy or power of attorney with respect to the Subject

                                      C-2

receipt and review of a copy of the Plan of Reorganization.

                  (e) NO ENCUMBRANCES. At all times during the term hereof, the
Subject Shares will be held by such Shareholder free and clear of all
Encumbrances whatsoever, except for any such Encumbrances arising hereunder.

                  (f) WAIVER OF APPRAISAL RIGHTS. Each Shareholder hereby waives
any rights of appraisal from the Merger that such Shareholder may have.

                  (g) NO SOLICITATION. Prior to the Termination Date, no
Shareholder shall, in its capacity as such, directly or indirectly (including
through advisors, agents or other intermediaries), solicit (including by way of
furnishing information) or respond to any inquiries or the making of any
proposal by any person or entity (other than Buyer or any Affiliate thereof)
with respect to ZMP that constitutes or could reasonably be expected to lead to
the acquisition of all or any portion of th capital stock of ZMP or ARA or
assets of ZMP or ARA (other than Inventory in the ordinary course of Business)
any business combination with ZMP or ARA or any other extraordinary transaction
involving or otherwise relating to ZMP or ARA. If any Shareholder, in its
capacity as such, receives any such inquiry or proposal, then such Shareholder
shall promptly inform Buyer of the terms and conditions, if any, of such inquiry
or proposal and the identity of the person making it. Each Shareholder, in its
capacity as such, will immediately cease and cause to be terminated any existing
activities, discussions or negotiations with any parties conducted heretofore
with respect to any of the foregoing.

                  (h) Each Shareholder agrees to exercise its "drag along"
rights under the Shareholders Agreement of ZMP dated as of January 27, 1997,
among ZMP and certain parties named therein as Acquisition may reasonably
request.

                  SECTION 2 . TRANSFER OF SUBJECT SHARES. During the term of
this Agreement, Shareholders agree not to (i) offer for sale, sell, transfer
(whether by merger, consolidation, operation of law or otherwise), tender,
pledge, encumber, assign or otherwise dispose of, enforce or permit the
execution of the provisions of any redemption agreement with ZMP or enter into
any contract, option or other arrangement or understanding with respect to or
consent to the offer for sale, sale, transfer (whether by merger, consolidation,
operation of law or otherwise), tender, pledge, encumbrance, assignment or other
disposition of, or exercise any discretionary powers to distribute, any Subject
Shares or any interest therein without the prior written consent of Buyer, (ii)
except as contemplated by this Agreement, grant any proxies or powers of
attorney with respect to any Subject Shares, deposit any Subject Shares into a
voting trust or enter into a voting agreement with respect to any Subject
Shares; or (iii) take any action that would make any representation or warranty
of such Shareholder contained herein untrue or incorrect or have the effect of
preventing or disabling such Shareholder from performing such Shareholder's
obligations under this Agreement.

                  SECTION 3. REPRESENTATIONS AND WARRANTIES OF SHAREHOLDERS.
Each Shareholder, jointly and severally, represents and warrants to Buyer,
subject to the terms, conditions and limitations set forth in the Plan of
Reorganization, as follows:

                                      C-3



                  (a) EXISTENCE AND POWER. Such Shareholder (1) is a partnership
duly formed, validly existing and in good standing under the laws of the State
of California and (2) has all requisite partnership power and authority to
execute and deliver this Agreement and to perform its obligations hereunder.


                  (b) AUTHORIZATION; CONTRAVENTION. The execution and delivery
by each Shareholder of this Agreement and the performance by it of its
obligations hereunder have, (1) been duly authorized by all necessary action
under such Shareholders organizational documents and (2) do not and will not
conflict with or result in a violation (with or without notice or lapse of time
or both) or give rise to any third party right of termination, cancellation,
material modification or acceleration pursuant to, (A) any provision of its
organizational documents or (B) any loan or credit agreement, note, mortgage,
bond, indenture, lease, benefit plan or other agreement, obligation, instrument,
permit, concession, franchise, license, judgment, order, decree, statute, law,
ordinance, injunction, rule or regulation applicable to such Shareholder, the
Subject Shares or any of such Shareholder's other properties or assets.

                  (c) BINDING EFFECT. This Agreement constitutes, or when
executed and delivered by Shareholders will constitute, a valid and binding
obligation of Shareholders, respectively, enforceable against Shareholders in
accordance with its terms, except as such enforceability may be limited by
bankruptcy, insolvency, reorganization, moratorium and similar laws relating to
or affecting creditors' generally, by general equity principles, (regardless of
whether such enforceability is considered in a proceeding in equity or at law)
or by an implied covenant of good faith and fair dealing.

                  (d) OWNERSHIP. Shareholders are the only beneficial or record
owners of the Subject Shares, free and clear of all Encumbrances other than
those arising hereunder or set forth on Schedule I hereto. The Shareholders do
not have record or beneficial ownership of any ZMP Common Stock other than as
set forth on Schedule 3.2B to the Plan of Reorganization. Shareholders have sole
power of disposition with respect to all of the Subject Shares and sole voting
power with respect to the matters set forth in Section 1 hereof and sole power
to demand appraisal rights, in each case with respect to all of the Subject
Shares with no restrictions on such rights, subject to applicable federal
securities laws and the terms of this Agreement.

                  (e) LITIGATION. There is no action, suit, investigation,
complaint or other proceeding pending against Shareholders, or, to the knowledge
of Shareholders, threatened against Shareholders or any other Person that
restricts in any material respect or prohibits (or, if successful, would
restrict or prohibit) the exercise by any party or beneficiary of its rights
hereunder or the performance by any party of its obligations hereunder.

                  SECTION 4. PROXY.

                  Each Shareholder hereby grants to, and appoints, Buyer and
Douglas Peacock, Chief Executive Officer of Buyer, and Nick Howley, President of
Buyer, in their respective capacities as officers of Buyer, and any individual
who shall hereafter succeed to any such office of Buyer, each of them
individually, such Shareholder's irrevocable (until the Termination Date) proxy
and attorney-in-fact (with full power of substitution) to vote the Subject
Shares as indicated in Section 1 above. Each Shareholder intends this proxy to
be irrevocable (until the 



                                      C-4


Termination Date) and coupled with an interest and will take such further action
and execute such other instruments as may be necessary to effectuate the intent
of this proxy and hereby revokes any proxy previously granted by such
Shareholder with respect to such Shareholder's Subject Shares.

                  SECTION 5. MISCELLANEOUS PROVISIONS.

                  (a) NOTICES. Any notice or other communication related hereto
must be given in writing and (a) delivered in person, (b) transmitted by
facsimile, (c) mailed by certified or registered mail, postage prepaid, receipt
requested or (d) overnight delivery service, given to the party at its address
stated on the signature pages of this Agreement or at any other address as the
party may specify for this purpose by notice to the other party. Each such
notice or other communication shall be effective (i) if given by
telecommunication, when transmitted to the applicable number and an appropriate
answerback is received, (ii) if given by mail, three days after such
communication is deposited in the mails with first class postage prepaid,
addressed as aforesaid or (iii) if given by any other means, when actually
received at such address.

                  (b) NO WAIVERS; REMEDIES; SPECIFIC PERFORMANCE.

                  (1) No failure on the part of any party to exercise or delay
         in exercising any right hereunder shall be deemed a waiver of thereof,
         nor shall any single or partial exercise of any right preclude any
         further or other exercise of such or any other right.

                  (2) In view of the uniqueness of the agreements contained
         herein and the transactions contemplated hereby and thereby and the
         fact that Buyer would not have an adequate remedy at law for money
         damages in the event that any obligation hereunder is not performed in
         accordance with its terms, each party to this Agreement therefore
         acknowledges that Buyer shall be entitled to specific enforcement of
         the terms hereof in addition to any other remedy to which Buyer may be
         entitled, at law or in equity.

                  (c) AMENDMENTS, ETC. This Agreement may not be amended, unless
         said amendment shall be (1) in writing and (2) signed and delivered by
         all parties hereto.


                  (d) SUCCESSORS AND ASSIGNS; THIRD PARTY BENEFICIARIES.

                  (1) Neither this Agreement nor any rights or obligations
hereunder are assignable.

                  (2) The provisions of this Agreement shall be binding upon and
inure solely to the benefit of the parties hereto and their respective permitted
heirs, executors, legal representatives, successors and assigns, and no other
person.

                  (e) GOVERNING LAW. This Agreement and all rights, remedies,
liabilities, powers and duties of the parties hereto shall be governed in
accordance with the laws of the State of California without regard to principles
of conflicts of laws. Each party hereby irrevocably submits to and accepts for
itself and its properties, generally and unconditionally, the exclusive

                                      C-5


jurisdiction of and service of process pursuant to the Laws of the State of
California and the rules of its courts, waives any defense of forum non
conveniens and agrees to be bound by any judgment rendered thereby arising under
or out of in respect of or in connection with this Agreement.

                  (f) SEVERABILITY OF PROVISIONS. If any provision of this
Agreement is determined to be invalid, illegal or unenforceable by any
Governmental Entity, the remaining provisions hereof to the extent permitted by
Law shall nevertheless remain in full force and effect, unless doing so would
result in an interpretation of this Agreement which is manifestly unjust.

                  (g) HEADINGS AND REFERENCES. The descriptive headings of the
Article and Section headings herein are included for convenience only and do not
constitute a part of this Agreement for any other purpose. References to

defined in this Agreement may, unless the context otherwise requires, be used in

Agreement of the word "include" or "including," when following any general
statement, term or matter, shall not be construed to limit such statement, term
or matter to the specific items or matters set forth immediately following such
word or to similar items or matters, whether or not nonlimiting language (such
as "without limitation" or "but not limited to" or words of similar import) is
used with reference thereto, but rather shall be deemed to refer to all other
items or matters that fall within the broadest possible scope of such general
statement, term or matter.

                  (h) ENTIRE AGREEMENT. This Agreement embodies the entire
agreement and understanding of Shareholders and Buyer, and supersedes all prior
agreements and understandings, both written and oral, with respect to the
subject matter hereof.

                  (i) SURVIVAL. Except as otherwise specifically provided

                  (j) FURTHER ASSURANCES. The parties hereto each agree to
execute, make, acknowledge, and deliver such instruments, agreements and other
documents as may be reasonably required to effectuate the purposes of this
Agreement and to consummate the transactions contemplated thereby.

                  (k) WAIVER OF JURY TRIAL. Each party waives any right to a
trial by jury in any Action to enforce or defend any right hereunder and agrees
that any Action shall be tried before a court and not before a jury.

                  (l) TERMINATION. Buyer may terminate this Agreement at any
time upon written notice to Shareholders. Unless terminated earlier by Buyer or
by mutual agreement of the parties, this Agreement shall terminate upon the

Plan of Reorganization pursuant to Section 6.1 thereof.

                                      C-6


                  (m) COUNTERPARTS. This Agreement and any amendment hereto may
be executed in one or more counterparts and by different parties in separate
counterparts, each of which shall be an original, with the same effect as if all
signatures were on the same instrument. All of such counterparts shall
constitute one and the same agreement (or other document) and shall become
effective (unless otherwise provided therein) when one or more counterparts have
been executed by each party and delivered to the other party.

rights of appraisal from the Merger that Shareholder may have.

Shareholder shall not, in its capacity as such, directly or indirectly
(including through advisors, agents or other intermediaries), solicit (including
by way of furnishing information) or respond to any inquiries or the making of

will immediately cease and cause to be terminated any existing activities,
discussions or negotiations with any parties conducted heretofore with respect
to any of the foregoing.

                  SECTION 2 . TRANSFER OF SUBJECT SHARES. During the term of

preventing or disabling Shareholder from performing Shareholder's obligations
under this Agreement.

                  SECTION 3. REPRESENTATIONS AND WARRANTIES OF SHAREHOLDER.
Shareholder represents and warrants to Buyer, subject to the terms, conditions
and limitations set forth in the Plan of Reorganization, as follows:

                  (a) CONTRAVENTION. The execution and delivery by Shareholder
of this Agreement and the performance by it of its obligations hereunder do not
and will not conflict with or result in a violation (with or without notice or
lapse of time or both) or give rise to any third party right of termination,
cancellation, material modification or acceleration pursuant to 



                                      D-3


any loan or credit agreement, note, mortgage, bond, indenture, lease, benefit
plan or other material agreement, obligation, instrument, permit, concession,
franchise, license, judgment, order, decree, statute, law, ordinance,
injunction, rule or regulation applicable to Shareholder, the Subject Shares or
any of Shareholder's other properties or assets.

                  (b) BINDING EFFECT. This Agreement constitutes, or when
executed and delivered by Shareholder will constitute, a valid and binding
obligation of Shareholder enforceable against Shareholder in accordance with its
terms, except as such enforceability may be limited by bankruptcy, insolvency,
reorganization, moratorium and similar laws relating to or affecting creditors'
generally, by general equity principles, (regardless of whether such
enforceability is considered in a proceeding i equity or at law) or by an
implied covenant of good faith and fair dealing.

                  (c) OWNERSHIP. Shareholder is the only beneficial or record
owner of the Subject Shares, free and clear of all Encumbrances other than those
arising hereunder or set forth on Schedule I hereto. Shareholder does not have
record or beneficial ownership of any ZMP Common Stock other than as set forth
on Schedule 3.2B to the Plan of Reorganization. Shareholder has sole power of
disposition with respect to all of the Subject Shares and sole voting power with
respect to the matters set forth in Section 1 hereof and sole power to demand
appraisal rights, in each case with respect to all of the Subject Shares with no
restrictions on such rights, subject to applicable federal securities laws and
the terms of this Agreement.

                  (d) LITIGATION. There is no action, suit, investigation,
complaint or other proceeding pending against Shareholder, or, to the knowledge
of Shareholders, threatened against Shareholder or any other Person that
restricts in any material respect or prohibits (or, if successful, would
restrict or prohibit) the exercise by any party or beneficiary of its rights
hereunder or the performance by any party of its obligations hereunder.

                  (e) INDEBTEDNESS. Shareholder acknowledges he owes to the
Company the Collins Note Amount (as defined in the Plan of Reorganization) which
will be repaid in full or canceled as of the Effective Time. In addition,
Shareholder acknowledges that the exercise price of the Collins Option is $39.41
per share.

                  SECTION 4. PROXY.

                  Shareholder hereby grants to, and appoints, Buyer and Douglas
Peacock, Chief Executive Officer of Buyer, and Nick Howley, President of Buyer,
in their respective capacities as officers of Buyer, and any individual who
shall hereafter succeed to any such office of Buyer, each of them individually,
Shareholder's irrevocable (until the Termination Date) proxy and
attorney-in-fact (with full power of substitution) to vote the Subject Shares as
indicated in Section 1 above. Shareholder intends this proxy to be irrevocable
(until the Termination Date) and coupled with an interest and will take such
further action and execute such other instruments as may be necessary to
effectuate the intent of this proxy and hereby revokes any proxy previously
granted by Shareholder with respect to Shareholder's Subject Shares.

                  SECTION 5. WARRANT CANCELLATION.

                                      D-4


                  Shareholder agrees that, in consideration of the payment to
him of the Merger Consideration with respect to the warrants ("Warrants") owned
by him to purchase 3,260 shares of common stock of ZMP, Inc., upon payment of
the Merger Consideration, all Warrants will be canceled and none of Buyer,
Acquisition, Surviving Corporation nor ZMP will have any further liability or
obligation to the undersigned with respect to the Warrants or any agreement,
understanding or commitment related thereto. Shareholder further agrees that he
will not exercise his Warrants for so long as this Agreement is in effect.

                  SECTION 6. MISCELLANEOUS PROVISIONS.

                  (a) NOTICES. Any notice or other communication related hereto
must be given in writing and (a) delivered in person, (b) transmitted by
facsimile, (c) mailed by certified or registered mail, postage prepaid, receipt
requested or (d) overnight delivery service, given to the party at its address
stated on the signature pages of this Agreement or at any other address as the
party may specify for this purpose by notice to the other party. Each such
notice or other communication shall be effective (i) if given by
telecommunication, when transmitted to the applicable number and an appropriate
answerback is received, (ii) if given by mail, three days after such

                  (b) NO WAIVERS; REMEDIES; SPECIFIC PERFORMANCE.

                  (1) No failure on the part of any party to exercise or delay
in exercising any right hereunder shall be deemed a waiver of thereof, nor shall
any single or partial exercise of any right preclude any further or other
exercise of such or any other right.

                  (2) In view of the uniqueness of the agreements contained
herein and the transactions contemplated hereby and thereby and the fact that
Buyer would not have an adequate remedy at law for money damages in the event
that any obligation hereunder is not performed in accordance with its terms,
each party to this Agreement therefore acknowledges that Buyer shall be entitled
to specific enforcement of the terms hereof in addition to any other remedy to
which Buyer may be entitled, at law or in equity.

                  (c) AMENDMENTS, ETC. This Agreement may not be amended, unless
said amendment shall be (1) in writing and (2) signed and delivered by all
parties hereto.
 
                  (d) SUCCESSORS AND ASSIGNS; THIRD PARTY BENEFICIARIES.

                  (1) Neither this Agreement nor any rights or obligations
hereunder are assignable.

                  (2) The provisions of this Agreement shall be binding upon and
inure solely to the benefit of the parties hereto and their respective permitted
heirs, executors, legal representatives, successors and assigns, and no other
person.

                                      D-5


                  (e) GOVERNING LAW. This Agreement and all rights, remedies,
liabilities, powers and duties of the parties hereto shall be governed in
accordance with the laws of the State of California without regard to principles
of conflicts of laws. Each party hereby irrevocably submits to and accepts for
itself and its properties, generally and unconditionally, the exclusive
jurisdiction of and service of process pursuant to the Laws of the State of
California and the rules of its courts, waives any defense of forum non
conveniens and agrees to be bound by any judgment rendered thereby arising under
or out of in respect of or in connection with this Agreement.

                  (f) SEVERABILITY OF PROVISIONS. If any provision of this
Agreement is determined to be invalid, illegal or unenforceable by any
Governmental Entity, the remaining provisions hereof to the extent permitted by
Law shall nevertheless remain in full force and effect, unless doing so would
result in an interpretation of this Agreement which is manifestly unjust.

                  (g) HEADINGS AND REFERENCES. The descriptive headings of the
Article and Section headings herein are included for convenience only and do not
constitute a part of this Agreement for any other purpose. References to

as "without limitation" or "but not limited to" or words of similar import) is
used with reference thereto, but rather shall be deemed to refer to all other
items or matters that fall within the broadest possible scope of such general
statement, term or matter.

                  (h) ENTIRE AGREEMENT. This Agreement embodies the entire
agreement and understanding of Shareholder and Buyer, and supersedes all prior
agreements and understandings, both written and oral, with respect to the
subject matter hereof.

                  (i) SURVIVAL. Except as otherwise specifically provided

execute, make, acknowledge, and deliver such instruments, agreements and other
documents as may be reasonably required to effectuate the purposes of this
Agreement and to consummate the transactions contemplated thereby.

                  (k) WAIVER OF JURY TRIAL. Each party waives any right to a
trial by jury in any Action to enforce or defend any right hereunder and agrees
that any Action shall be tried before a court and not before a jury.

                                      D-6

be executed in one or more counterparts and by different parties in separate
counterparts, each of which shall be an original, with the same effect as if all
signatures were on the same instrument. All of such counterparts shall
constitute one and the same agreement (or other document) and shall become
effective (unless otherwise provided therein) when one or more counterparts have
been executed by each party and delivered to the other party.

                                   EXHIBIT D-1

                    TEXT OF OPINION OF COUNSEL TO THE COMPANY


1. Each of ZMP, Inc. ("ZMP") and Adams Rite Aerospace, Inc. ("ARA"), is duly
incorporated, and is validly existing and in good standing under the laws of the
State of California. ZMP has the corporate power to execute and deliver each of
the Agreement and the Agreement of Merger (collectively, the "Agreements") and
to perform its obligations thereunder. Each of ZMP and ARA has corporate power
to own and lease its properties and assets.

2. The execution, delivery and performance of the Agreements have been duly
authorized by all necessary corporate action on the part of ZMP and all
necessary partnership action on the part of the Shareholders' Representative and
the Agreements to which each of them is a party have been duly executed and
delivered by ZMP and the Shareholders' Representative.

3. Each of the Agreements constitutes the legally valid and binding obligation
of ZMP, enforceable against ZMP in accordance with its terms, except as may be
limited by bankruptcy, insolvency, reorganization, moratorium or similar laws
relating to or affecting creditors' rights generally (including, without
limitation, fraudulent conveyance laws) and by general principles of equity,
including, without limitation, concepts of materiality, reasonableness, good
faith and fair dealing and the possible unavailability of specific performance
or injunctive relief, regardless of whether considered in a proceeding in equity
or at law.

4. ZMP's execution and delivery of, and performance of its obligations under the
Agreements on or prior to the date of this opinion do not (i) violate ZMP's or
ARA's Articles of Incorporation and By-laws, (ii) violate, breach, or result in
a default under any existing obligation of or restriction on ZMP or ARA under
any other agreements identified in ZMP's Certificate, or (iii) breach or
otherwise violate any existing obligation of or restriction on ZMP or ARA under
any order, judgment or decree of any California or federal court or governmental
authority binding on ZMP or ARA identified in ZMP's Certificate.

5. The execution and delivery by ZMP and the Shareholders' Representative of,
and performance of their respective obligations under, the Agreements to which
each of them is a party do not violate any California or federal statute, rule
or regulation that we have, in the exercise of customary professional diligence,
recognized as applicable to ZMP, ARA, the Shareholders' Representative or to
transactions of the type contemplated by the Agreements.

6. No order, consent, permit or approval of any California or federal
governmental authority that we have, in the exercise of customary professional
diligence, recognized as applicable to ZMP, ARA, the Shareholders'
Representative or to transactions of the type contemplated by the Agreements is
required on the part of ZMP or the Shareholders' Representative for the
execution and delivery of, and performance of its obligations on or prior to the
date of this opinion under, the Agreements to which each of them is a party,
except for such as have been obtained.

7. Assuming due authorization of the Merger by all necessary corporate action on
the part of Buyer and Acquisition and that Buyer and Acquisition have taken all
action they are required to take, upon the filing of the Articles of Merger by
the Secretary of State of the State of California, 



                                     D-1-1


the Merger will be validly consummated in accordance with the Agreement, the
Agreement of Merger and the General Corporation Law of the State of California.

8. The authorized capital stock of ZMP is as set forth in Section 3.2B of the
Disclosure Schedule. The authorized capital stock of ARA consists of
_____________ shares of common stock. Based solely upon a review of records
certified to us as the stock record books of ZMP and ARA, and without
independent investigation, (i) the number of outstanding shares of ZMP's capital
stock is as set forth in Section 3.2B of the Disclosure Schedule and (ii) there
are 50,000 outstanding shares of ARA common stock, all of which are owned of
record by ZMP. Based solely upon (x) a review of such stock record books of ZMP
and ARA, (y) records certified to us as the minute books of ZMP and ARA and (z)
matters set forth in the ZMP Certificate, and without independent investigation,
the outstanding shares of capital stock of each of ZMP and ARA have been duly
authorized by all necessary corporate action on the part of each of ZMP and ARA,
respectively, and are validly issued, fully paid and nonassessable. Holders of
the capital stock of ZMP and of ARA are not entitled to any preemptive right to
subscribe to any additional shares of their respective capital stock under their
respective Articles of Incorporation or Bylaws.

                                   EXHIBIT D-2

               TEXT OF OPINION OF COUNSEL TO BUYER AND ACQUISITION

1. TransDigm, Inc. ("BUYER") has been duly incorporated and is validly existing
and in good standing under the laws of the State of Delaware, with corporate
power to enter into the Agreement and the Agreement of Merger (collectively, the
"AGREEMENTS"), and to perform its obligations thereunder.

2. The execution, delivery and performance of the Agreements have been duly
authorized by all necessary corporate action on the part of Buyer, and the
Agreements have been duly executed and delivered by Buyer.

3. The Agreements constitute the valid and binding obligations of Buyer,
enforceable against Buyer in accordance with their respective terms. The
opinions expressed in this paragraph 3 are subject to the following limitations,
qualifications and exceptions: (i) the effect of bankruptcy, insolvency,
reorganization, moratorium or other similar laws now or hereafter in effect
relating to or affecting the rights or remedies of creditors; (ii) the effect of
general principles of equity, whether enforcement is considered in a proceeding
in equity or at law, and the discretion of the court before which any proceeding
therefor may be brought; (iii) the unenforceability under certain circumstances
under law or court decisions of provisions providing for the indemnification of
or contribution to a party with respect to a liability where such
indemnification or contribution is contrary to public policy; and (iv) the
unenforceability of any provision requiring the payment of attorney's fees,
except to the extent that a court determines such fees to be reasonable.

4. Neither the execution and delivery by Buyer of the Agreements nor the
consummation of the Merger contemplated by the Agreement will (i) result in any
breach or violation of the certificate of incorporation or bylaws of Buyer; (ii)
result in any violation of any applicable federal or California statute, rule or
regulation applicable to Buyer; (iii) require any consent, approval or
authorization, declaration or filing by Buyer under any federal or California
statute, rule or regulation applicable to Buyer; (iv) result in a breach of, or
constitute a default under, any agreement or instrument identified to us as
material by Buyer, which agreements are listed on Schedule I hereto; or (v)
breach or otherwise violate any of the terms of or provisions of any orders,
judgments or decrees listed on Schedule I hereto, which have been identified to
us by Buyer as being all of the orders, judgments and decrees that are material
to the financial condition or results of operations of Buyer. No opinion is
expressed in clause (ii) or (iii) of this paragraph 4 as to the application or
contravention of any antifraud laws, antitrust laws or trade regulations. The
opinions set forth in this paragraph 4 are based upon our consideration of only
those statutes, rules and regulations that, in our experience, are normally
applicable to transactions such as those contemplated by the Agreement.

5. Acquisition has been duly incorporated and is validly existing and in good
standing under the laws of the State of California, with corporate power and
authority to enter into the Agreements and all documents in connection with the
Agreements to which Acquisition is a party (collectively, the "ACQUISITION
AGREEMENTS"), and to perform its obligations thereunder.



                                     D-2-1


6. The execution, delivery and performance of the Acquisition Agreements have
been duly authorized by all necessary corporate action on the part of
Acquisition, and the Acquisition Agreements have been duly executed and
delivered by Acquisition.

7. The Acquisition Agreements constitute the valid and binding obligations of
Acquisition, enforceable against Acquisition, in accordance with their
respective terms. The opinions expressed in this paragraph 7 are subject to the
following limitations, qualifications and exceptions: (i) the effect of
bankruptcy, insolvency, reorganization, moratorium or other similar laws now or
hereafter in effect relating to or affecting the rights or remedies of
creditors; (ii) the effect of general principles of equity, whether enforcement
is considered in a proceeding in equity or at law, and the discretion of the
court before which any proceeding therefor may be brought; (iii) the
unenforceability under certain circumstances under law or court decisions of
provisions providing for the indemnification of or contribution to a party with
respect to liability where such indemnification or contribution is contrary to
public policy; and (iv) the unenforceability of any provision requiring the
payment of attorney's fees, except to the extent that a court determines such
fees to be reasonable.

8. Neither the execution and delivery by Acquisition of the Agreement nor the
consummation of the Merger contemplated by the Agreement will (i) result in any
breach or violation of the articles of incorporation or bylaws of Acquisition;
(ii) result in any violation of any applicable federal or California statute,
rule or regulation applicable to Acquisition; (iii) require any consent,
approval or authorization, declaration or filing by Acquisition under any
federal or California statute, rule or regulation applicable to Acquisition;
(iv) result in a breach of, or constitute a default under, any agreement or
instrument identified to us as material by Acquisition, which agreements are
listed on Schedule I hereto; or (v) breach or otherwise violate any of the terms
of or provisions of any, orders, judgments or decrees listed on Schedule I
hereto, which have been identified to us by Buyer as being all of the orders,
judgments and decrees that are material to the financial condition or results of
operations of Buyer. No opinion is expressed in clause (ii) or (iii) of this
paragraph 8 as to the application or contravention of any antifraud laws,
antitrust laws or trade regulations. The opinions set forth in this paragraph 8
are based upon our consideration of only those statutes, rules and regulations
that, in our experience, are normally applicable to transactions such as those
