of performance greater than one year which are true and correct in all material
respects.

               -------------------                                             
which Seller is party or by which it or any of the Assets is bound or affected
are in full force and effect and valid, binding and enforceable in accordance
with their terms. Seller has fulfilled, or taken all action necessary to enable
it to fulfill when due, all of its material obligations under each of such
Contracts and Facility Leases, and is not behind any performance time schedule
imposed on Seller by any such Contract or a Facility Lease with a value in
excess of $100,000, which has not been excused or waived without additional cost
or penalty, except as set forth on Schedule 4.6(b). All parties to such
Contracts and Facility Leases have complied in all material respects with the
provisions thereof, no party is in Default thereunder and no notice of any claim
of Default has been given to Seller. Seller has no reason to believe that the
products and services called for by any unfinished Contract cannot be supplied
in accordance with the terms of such Contract, including time specifications,
and has no reason to believe that any unfinished Contract will upon performance
by Seller result in a loss to Seller. With respect to any Facility Leases,
Seller has not received any notice of cancellation or termination under any
option or right reserved to the lessor, or any notice of Default, thereunder.
Except as set forth in Schedule 4.6(b), the enforceability and terms of any

no consents are required to transfer any such Contracts to Buyer.

          ------- 

          (a)  Schedule 4.8 lists all of Seller's Permits related to the conduct
of the Business or the operation of the Assets. Seller has, and at all times has
had, all material Permits required under any Regulation (including Environmental
Laws) with respect to the operation of its Business or the ownership, use and
operation of the Assets, and owns or possesses such Permits free and clear of
all Encumbrances. Seller is not in Default, nor has it received any notice of
any claim of Default, nor is any audit, investigation or other review pending to
determine the existence of any Default, with respect to any such Permit. Except
as otherwise governed by law, all such Permits are renewable by their terms or
in the ordinary course of business without the need to comply with any special
qualification procedures or to pay any amounts other than routine filing fees
and, except as set forth on Schedule 4.8, may be assigned to Buyer and will not
be materially adversely affected by the completion of the transactions
contemplated by this Agreement. No present or former shareholder, director,
officer or employee of Seller or any affiliate thereof, or any other person,
firm, corporation or other entity, owns or has any proprietary, financial or
other interest (direct or indirect) in any Permit which Seller owns, possesses
or uses.


          (b)  Other than in connection with or in compliance with the
provisions of the HSR Act, and except as disclosed on Schedule 4.8 hereto, no
notice to, authorization, consent or approval of, declaration, filing or
registration with, or Permit from, any domestic or foreign governmental or
regulatory body or authority, or any other person or entity including any
private third party, is required to be made or obtained by Seller in connection
with the execution,

                                       19
<PAGE>
 
delivery or performance of this Agreement, the transfer of the Assets to Buyer,
and the consummation of the transactions contemplated hereby.

     4.9  No Conflict or Violation. Except as set forth on Schedule 4.9, Neither
          ------------------------                                              
the execution, delivery or performance of this Agreement nor the consummation of
the transactions contemplated hereby, nor compliance by Seller with any of the
provisions hereof, will (a) violate or conflict with or result in any breach of
any provision of the charter or bylaws of Seller, (b) violate, conflict with, or
result in or constitute (with or without due notice or lapse of time or both) a
Default under, or result in the termination of, or accelerate the performance
required by, or result in a right of termination or acceleration under, or

the terms, conditions or provisions of any Contract, Facility Lease or Permit,
(i) to which Seller is a party or (ii) by which the Assets are bound, (c)
violate any Regulation or Court Order, (d) impose any Encumbrance on the Assets
or the Business, except in the case of each of clauses (b) and (d) above, for

the Assets, the Business or on the ability of Seller to consummate the
transactions contemplated hereby.

     4.10 Balance Sheet. Seller has heretofore delivered to Buyer a complete and
          -------------                                                         
accurate copy of the Balance Sheet and revenue, direct material cost and direct
labor cost data for the past three fiscal years related solely to the Business
(the "Financial Data"). The Balance Sheet and the Financial Data (a) are in
      --------------
accordance with the books and records of Seller and (b) have been prepared in
accordance with generally accepted accounting principles. The Balance Sheet
fairly and accurately presents the assets, Liabilities (including all reserves)
and financial position of the Business as of the Balance Sheet Date. The
Financial Data fairly and accurately presents the revenue data, direct material
cost data and direct labor cost data for the last three fiscal years. The
Balance Sheet does not include any assets not included in the Assets and the
Financial Data does not reflect revenues or costs of businesses or products not
included in the Business.


     4.11 Projections. Seller has previously delivered to Buyer summary
          -----------

"Projections"). No facts have come to the attention of Seller which would, in
------------
Seller's opinion, require Seller to revise or modify the Projections, their
underlying assumptions or other estimates or conclusions derived from such
assumptions.


     4.12 Books and Records. Seller has made and kept (and given Buyer access
          -----------------                                                  
to) Books and Records and accounts with respect to the Business, which, in
reasonable detail, accurately and fairly reflect the activities of Seller.

     4.13 Litigation. Except as set forth on Schedule 4.13, there are no Actions
          ----------                                                            
pending, or to the best of Seller's knowledge, threatened or anticipated (a)
against, related to or affecting the Business or the Assets (including with
respect to Environmental Laws), (b) seeking to delay, limit or enjoin the
transactions contemplated by this Agreement, or (c) that involve the risk of

                                       20
<PAGE>
 
criminal liability. Seller is not in Default with respect to or subject to any
Court Order, and there are no unsatisfied judgments against the Business or the
Assets. There is not a reasonable likelihood of an materially adverse
determination of any pending Actions. There are no Court Orders or agreements
with, or liens by, any governmental authority or quasi-governmental entity
relating to any Environmental Law which regulate, obligate, bind or in any way
affect the Business or the use or operation of the Assets. Except as set forth
on Schedule 4.13, there is no Action initiated by Seller which is currently
pending, or which Seller presently intends to initiate, which relate to the
Business or the use or the operation of the Assets.

     4.14 Liabilities. Other than Excluded Liabilities and except as set forth
          -----------                                                         
on Schedule 4.14, and solely with respect to the Business, Seller has no
material Liabilities due or to become due, except (a) Liabilities which are set
forth or reserved for on the Balance Sheet, which have not been paid or
discharged since the Balance Sheet Date, (b) Liabilities arising in the ordinary
course of business under Contracts, Facility Leases, Permits and other business
arrangements described in Schedule 4.14 (and under those Contracts, Facility
Leases and Permits which are not required to be disclosed on Schedule 4.14) and
(c) Liabilities incurred since the Balance Sheet Date in the ordinary course of
business and in accordance with this Agreement (none of which relates to any
Default under any Contract or Facility Lease, breach of warranty, tort,
infringement or violation of any Regulation or Court Order or arose out of any
Action) and none of which, individually or in the aggregate, has or would have a
material adverse effect on the Business or the Assets.

     4.15 Compliance with Law. Seller in its conduct of the Business has not
          -------------------                                               
violated in any way that would have or result in a material adverse effect and
is in material compliance with all Regulations and Court Orders relating to the
Assets or the Business. Without limitation of the foregoing, Seller has not
violated any provision of the Export Administration Amendments of 1977, the
Truth In Negotiations Act, the Foreign Corrupt Practices Act of 1977, or the
Arms Export Control Act and the regulations promulgated under any of the
foregoing, all as amended. Seller has not received any notice to the effect
that, or otherwise been advised that, it is not in compliance with any such
Regulations or Court Orders, there is no pending investigation or other review
pending to determine the existence of any such lack of compliance, and Seller
has no reason to believe, and is not aware of, any existing circumstances which
are likely to result in material violations of any of the foregoing. Seller has
not received any notice of any change in any Court Order, and, to the best
knowledge of Seller, there is no, contemplated change in any Regulations that
would have a material adverse effect on the conduct of the Business or the
ownership, operation, use or maintenance of the Assets.

     4.16 No Brokers. Neither Seller nor any of its officers, directors,
          ----------                                                    
employees, shareholders or affiliates has employed or made any agreement with
any broker, finder or similar agent or any person or firm which will result in
the obligation of Seller, Buyer or any of their respective affiliates to pay any
finder's fee, brokerage fees or commission or similar payment in connection with
the transactions contemplated hereby, except amounts owed to NationsBanc
Capital Markets, Inc. All claims of, or obligations to, NationsBanc Capital
Markets, Inc. shall be the responsibility of and shall be paid by Seller and
shall result in no

                                       21
<PAGE>
 
liability to Buyer.

     4.17 No Other Agreements to Sell the Assets. Neither Seller nor any of its
          --------------------------------------                               
officers, directors, shareholders or affiliates has any commitment or legal
obligation, absolute or contingent, to any other person or firm other than the
Buyer to sell, assign, transfer or effect a sale of any of the Assets (other
than inventory in the ordinary course of business), to sell or effect a sale of
a majority of the capital stock of Seller, to effect any merger, consolidation,
liquidation, dissolution or other reorganization of Seller, or to enter into any
agreement or cause the entering into of an agreement with respect to any of the
foregoing.

     4.18 Proprietary Rights.
          ------------------ 

          (a) Proprietary Rights. Schedule 4.18(a) contains a true and complete
              ------------------                                            
list all of the Proprietary Rights. Schedule 4.18(a) also sets forth: (i) for
each Patent, the number, normal expiration date and subject matter for each
country in which such Patent has been issued, or, if applicable, the application
number, date of filing and subject matter for each country, (ii) for each
Trademark, the application serial number or registration number, the class of
goods covered and the expiration date for each country in which a Trademark has
been registered and ((iii)) for each Copyright, the number and date of filing
for each country in which a Copyright has been filed. The Proprietary Rights
listed in Schedule 4.18(a) are all those used or necessary in connection with
the operation of the Business. All of the material Proprietary Rights are valid
and subsisting.

          (b) Royalties and Licenses. Except as set forth on Schedule 4.18(b),
              ----------------------                                          
Seller does not have any obligation to compensate any person for the use of any
of the Proprietary Rights nor has Seller granted to any person any license,
option or other rights to use in any manner any of the Proprietary Rights,
whether requiring the payment of royalties or not.


          (c) Ownership and Protection of Proprietary Rights. Seller owns, or is
              ----------------------------------------------                    
licensed or otherwise has a valid right to use each of the Proprietary Rights
set forth on Schedule 4.18(a), and such Proprietary Rights will not cease to be
valid rights of Seller by reason of the execution, delivery and performance of
this Agreement, except as transferred to Buyer as contemplated herein. Seller
has not received any notice of invalidity or infringement of any rights of
others with respect to such Trademarks. Seller has taken all reasonable and
prudent steps to protect the Proprietary Rights from infringement by any other
person. No other person (i) has the right to use any of Seller's Trademarks on
the goods on which they are now being used either in identical form or in such
near resemblance thereto as to be likely, when applied to the goods of any such
person, to cause confusion with such Trademarks or to cause a mistake or to
deceive, (ii) has notified Seller that it is claiming any ownership of or right
to use such Proprietary Rights, or (iii) to the best of Seller's knowledge, is
infringing upon any such Proprietary Rights in any way. Seller's use of the
Proprietary Rights does not and will not conflict with, infringe upon or
otherwise violate the valid rights of any third party in or to such Proprietary
Rights, and no Action has been instituted against or notices received by Seller
that are presently outstanding alleging that Seller's use of the Proprietary
Rights infringes upon or

                                       22
<PAGE>
 
otherwise violates any rights of a third party in or to such Proprietary Rights.
There are not, and it is reasonably expected that after the Closing there will
not be, any restrictions on Seller's, or Buyer's, as the case may be, right to
sell products manufactured by Seller or Buyer, as the case may be, in connection
with the Business.

     4.19 Transactions with Certain Persons. No officer, director or employee of
          ---------------------------------

within the last three years has been, a party to any transaction with Seller
relating to the Business, including without limitation, any contract, agreement
or other arrangement (a) providing for the furnishing of services by, (b)
providing for the rental of real or personal property from, or (c) otherwise
requiring payments to (other than for services as officers, directors or
employees of Seller) any such person or to a corporation, partnership, trust or
other entity in which any such person has an interest as a stockholder, owner,
officer, director, trustee or partner.

              ---------------------                                           
Seller is now or has been a member) has timely filed with the appropriate taxing
authorities all returns (including without limitation information returns and
other material information) in respect of Taxes required to be filed through the

as of the date of filing, be true, complete and correct in all material
respects.

          (b) Payment of Taxes. All Taxes, in respect of periods beginning
              ----------------

adequate reserve has been established therefor, and Seller does not have any
material Liability for Taxes in excess of the amounts so paid or reserves so
established.

          (c) Lien. There are no liens for Taxes (other than for current Taxes
              ----

A of Chapter 3 of the Code or of any other provision of law.

     4.21 Insurance. Seller has previously delivered to Buyer a complete and
          ---------

as to each policy or binder the carrier, policy number, coverage limits and

unpaid premiums except in the ordinary course of business and no notice of
cancellation or nonrenewal of any such coverage has been received. There are no

and (b) any material failure of Seller or any of its affiliates or
Representatives, to comply with or satisfy any covenant, condition or agreement
to be complied with or satisfied by it under this Agreement or any exhibit or

     -----------------                                                     
Buyer shall determine in its sole discretion. Seller shall cooperate with and
use its best efforts to assist Buyer in its efforts to secure satisfactory
employment arrangements with those employees of Seller to whom Buyer makes
offers of employment. Seller shall terminate the employment of all Rehired
Employees immediately prior to the Closing whether or not such Rehired Employees

employee positions with Seller in any of its other divisions or businesses.

          (b) Seller shall be solely responsible for all of the ERISA Plans and

          (c) Nothing contained in this Agreement shall confer upon any Rehired

anything herein interfere with the right of Buyer to terminate the employment of
any of the Rehired Employees at any time, with or without cause, or restrict

                                       35
<PAGE>
 
independent business judgment in modifying any of the terms and conditions of
the employment of the Rehired Employees.

          (d) No provision of this Agreement shall create any third party
beneficiary rights in any Rehired Employee, any beneficiary or dependents

the compensation, terms and conditions of employment and benefits that may be
provided to any Rehired Employee by Buyer or under any benefit plan which Buyer
may maintain.

          (e) Seller shall not, directly or indirectly, hire or offer employment
to any employee of Seller whose employment is continued by Buyer after the
Closing Date or any employee of Buyer or any successor or affiliate of Buyer
which is engaged in the Business, unless Buyer first terminates the employment

employment.

          (f) Seller agrees that Buyer has no COBRA obligation with respect to
any employees of Seller not hired by Buyer.

claim, contract, lease, agreement, license, commitment, sales order, purchase
order or any claim or right or any benefit arising thereunder or resulting
therefrom if an attempted assignment thereof, without the consent of a third
party thereto, would constitute a breach thereof or in any way affect the rights
of Buyer or Seller thereunder. If such consent is not obtained, or if an
attempted assignment thereof would be ineffective or would affect the rights of
Seller thereunder so that Buyer would not in fact receive all such rights,
Seller will cooperate with Buyer in any lawful arrangement designed to provide
Buyer the benefits under such claims, contracts, leases, agreements, licenses,
commitments, sales orders or purchase orders, including the enforcement for the
benefit of Buyer of any and all rights of Seller against a third party thereto
arising out of the breach or cancellation by such third party or otherwise; and

any actions taken in accordance with Section 6.7 hereof, Seller shall assist
Buyer in novating or obtaining consents to the assignment of the Government
Contracts and Foreign Government Contracts in favor of Buyer. In the event that
novations can not be obtained in a timely fashion and Buyer elects, in its sole
discretion, to close the transactions contemplated by this Agreement without
obtaining novations or obtaining consents to assignment with respect to all of
the Government Contracts and Foreign Government Contracts, then Seller shall
cooperate with Buyer to make alternative arrangements (satisfactory to Buyer in
its absolute discretion) with respect to the performance of such Government
Contracts after the Closing and until such novations are obtained in accordance
with the Transition Services Agreement. Seller also shall enter into such
agreements as may be reasonably requested by Buyer with respect to any such

          -----------------------                                            
"Closing Date Adjustment") by (i) the amount, if any, that the current assets

statement of current assets and supporting schedules of the Business and the
Assets (excluding the Excluded Assets) as of the fiscal month end corresponding

                      ----------------
Seller as having been prepared in the ordinary course of business, consistent

payments on the August Statement (the "Closing Date Estimate").
                                       ---------------------

          (b) Within 45 days after the Closing, Buyer shall prepare and deliver
to Seller a statement of current assets, unearned revenues and advance payments
and supporting schedules of the Business and the Assets (excluding the Excluded
Assets) as of the Closing Date, certified by a financial officer of Buyer as
having been prepared in the ordinary course of business, consistent with the
preparation of the August Statement and in accordance with GAAP (the "Closing
                                                                      -------
Date Statement") and a computation of the final Closing Date Adjustment. In the
-------------
event the final Closing Date Adjustment is greater or lesser than the Closing
Date Estimate, the party owing a final adjusting payment to the other will make
such payment within 30 days after delivery of the Closing Date Statement,
subject to subsection (c) below.

          (c) Within the 30 day period following the delivery of the Closing
Date Statement, Seller shall have the right to notify Buyer in writing that it
disputes the Closing Date Statement. If Seller does not so notify Buyer within
such 30 day period, the Closing Date Statement shall be final and binding upon
the parties and the payment required by subsection (b) hereof, if any, shall be
made. In the event Seller does deliver a notice of dispute within the 30 day
period, Seller and Buyer shall use their best efforts to resolve such dispute.
If such a

                                       37
<PAGE>
 
settlement is not reached within 30 days after delivery by Seller of written
notice of the dispute, Buyer and Seller will submit the unresolved portion of

engaged by Buyer, Seller or any of their affiliates. The decision of such
accounting firm shall be final and binding on the parties, and Buyer and Seller
shall equally bear the costs of such accounting firm. Payments of any amounts
owed by one party to the other shall be made within 15 days after the resolution
of a dispute.

          --------------------------                                            
other person shall have been instituted or threatened which questions the
validity or legality of the transactions contemplated hereby and which could

              -------------                                                 
duly incorporated, validly existing and in good standing under the laws of its
respective jurisdiction of incorporation; each of Whittaker and Services is duly
qualified to do business as a foreign corporation and is in good standing in
each jurisdiction where the ownership or leasing of its property or nature of
the Business requires such qualification, except where the failure to be so

                                       40
<PAGE>
 
qualified would not have a material adverse effect on the Business or the
Assets;

          (b) Corporate Power and Authority. Whittaker and Services have the
              -----------------------------                                 
necessary corporate power and authority to enter into this Agreement and the

performance of this Agreement and the Ancillary Agreements by Whittaker and
Services have been duly authorized by all necessary corporate action of
Whittaker and Services, and this Agreement and the Ancillary Agreements have
been duly executed and delivered by Whittaker and Services, and this Agreement
and each Ancillary Agreement constitute legally valid and binding obligations of
Whittaker and Services, enforceable against each of them in accordance with
their terms, except as limited by (i) bankruptcy, insolvency, reorganization,
moratorium or other similar laws relating to creditors' rights generally or by
equitable principles (whether considered in an action at law or in equity), (ii)
limitations imposed by federal or state law or equitable principles upon the
availability of specific performance, injunctive relief or other equitable
remedies, or (iii) other customary limitations reasonably satisfactory to
Buyer's counsel;

          (d) No Breach of Contracts. Neither the execution and delivery of this
              ----------------------                                            
Agreement or the Ancillary Agreements by Whittaker or Services nor the
consummation of the transactions contemplated hereby or thereby will (i) violate
the Articles of Incorporation or Bylaws of Whittaker or Services, (ii) to the
knowledge of such counsel, cause a Default under any term or provision of any
material contract related to the Business to which Whittaker or Services is a
party, or (iii) to the best knowledge of such counsel, violate any Court Order
applicable to Whittaker or Services; and

          (e) No Violation of Law. Neither the execution and performance of this

(a) as to matters governed by the laws of jurisdictions other than states in
which they maintain offices, upon opinions of local counsel satisfactory to such
counsel, and (b) as to factual matters, upon certificates and assurances of
public officials and officers of Whittaker and Services. In addition, such
opinions may be subject to such additional qualifications and exceptions as are
reasonably acceptable to counsel to Buyer.

                      RISK OF LOSS: CONSENTS TO ASSIGNMENT
                      ------------------------------------

     9.1  Risk of Loss. From the date hereof through the Closing Date, all risk
          ------------                                                         
of loss or damage to the property included in the Assets shall be borne by
Seller, and thereafter shall be borne by Buyer. If any portion of the Assets is
destroyed or damaged by fire or any other cause on or prior to the Closing Date,
other than use, wear or loss in the ordinary course of business, Seller shall
give written notice to Buyer as soon as practicable after, but in any event
within five calendar days of, discovery of such damage or destruction, the
amount of insurance, if any, covering such Assets and the amount, if any, which
Seller is otherwise entitled to receive as a consequence. Prior to the Closing,
Buyer shall have the option, which shall be exercised by written notice to
Seller within ten calendar days after receipt of Seller's notice or if there are
not ten calendar days prior to the Closing Date, as soon as practicable prior to
the Closing Date, of (a) accepting such Assets in their destroyed or damaged
condition in which event Buyer shall be entitled to the proceeds of any
insurance or other proceeds payable with respect to such loss and to
indemnification for any uninsured portion of such loss pursuant to Section 10.4,
and the

                                       42
<PAGE>
 
full Purchase Price shall be paid for such Assets, (b) excluding such Assets
from this Agreement, in which event the Purchase Price shall be reduced by the
amount allocated to such Assets, as mutually agreed between the parties or (c)
terminating this Agreement in accordance with Section 11.1. If Buyer accepts
such Assets, then after the Closing, any insurance or other proceeds shall
belong, and shall be assigned to, Buyer without any reduction in the Purchase
Price; otherwise, such insurance proceeds shall belong to Seller.

     9.2  Consents to Assignment. Anything in this Agreement to the contrary
          ----------------------                                            
notwithstanding, this Agreement shall not constitute an agreement to assign any
Contract, Facility Lease, Permit or any claim or right or any benefit arising
thereunder or resulting therefrom if an attempted assignment thereof, without
the consent of a third party thereto, would constitute a Default thereof or in
any way adversely affect the rights of Buyer thereunder. If such consent is not
obtained, or if an attempted assignment thereof would be ineffective or would
affect the rights thereunder so that Buyer would not receive all such rights,
Seller will cooperate with Buyer, in all reasonable respects, to provide to
Buyer the benefits under any such Contract, Facility Lease, Permit or any claim
or right, including without limitation enforcement for the benefit of Buyer of
any and all rights of Seller against a third party thereto arising out of the
Default or cancellation by such third party or otherwise. Nothing in this
Section 9.2 shall affect Buyer's right to terminate this Agreement under
Sections 8.2 and 11.1 in the event that any consent or approval to the transfer
of any Asset is not obtained.


                                   ARTICLE X

                 ACTIONS BY SELLER AND BUYER AFTER THE CLOSING

     10.1 Collection of Accounts Receivable and Letters of Credit. At the

shall have the right and authority to collect for Buyer's or its designee's
account, all receivables, letters of credit and other items which constitute a
part of the Assets, and Seller shall within 48 hours after receipt of any
payment in respect of any of the foregoing, properly endorse and deliver to
Buyer any letters of credit, documents, cash or checks received on account of or
otherwise relating to any such receivables, letters of credit or other items.
Seller shall promptly transfer or deliver to Buyer or its designee any cash or
other property that Seller may receive in respect of any deposit, prepaid

              -----------------                                               
and make available to the other party, during normal business hours, all Books
and Records, information and employees (without substantial disruption of
employment) retained and remaining in existence after the Closing which are
necessary or useful in connection with any tax inquiry, audit, investigation or
dispute, any litigation or investigation or any other matter

                                       43
<PAGE>
 
requiring any such Books and Records, information or employees for any
reasonable business purpose. The party requesting any such Books and Records,
information or employees shall bear all of the out-of-pocket costs and expenses
(including without limitation attorneys' fees, but excluding reimbursement for
salaries and employee benefits) reasonably incurred in connection with providing
such Books and Records, information or employees. All information received
pursuant to this Section 10.2(a) shall be subject to the terms of the
Confidentiality Agreement.

          (b) Cooperation and Records Retention. Seller and Buyer shall (i) each
              ---------------------------------                                 
provide the other with such assistance as may reasonably be requested by any of
them in connection with the preparation of any return, audit, or other
examination by any taxing authority or judicial or administrative proceedings
relating to Liability for Taxes, (ii) each retain and provide the other with any
records or other information that may be relevant to such return, audit or
examination, proceeding or determination, and (iii) each provide the other with
any final determination of any such audit or examination, proceeding, or
determination that affects any amount required to be shown on any tax return of
the other for any period. Without limiting the generality of the foregoing,
Buyer and Seller shall each retain, until the applicable statutes of limitations
(including any extensions) have expired, copies of all tax returns, supporting
work schedules, and other records or information that may be relevant to such
returns for all tax periods or portions thereof ending on or before the Closing
Date and shall not destroy or otherwise dispose of any such records without
first providing the other party with a reasonable opportunity to review and copy
the same.

          (c) Payment of Liabilities. Following the Closing Date, Seller shall
              ----------------------                                          
pay promptly when due all of the debts and Liabilities of Seller, including any
Liability for Taxes, other than Assumed Liabilities; provided, however, this
covenant shall not apply to that portion (or all) of any debt that Seller is
contesting in good faith.

     10.3 Survival of Representations. Etc. All of the representations and
          ----------- --------------------                                
warranties made by each party in this Agreement or in any attachment, the
Disclosure Schedule, certificate, document or list delivered by any such party
pursuant hereto shall survive the Closing for a period of (and claims based upon
or arising out of such representations, warranties, covenants and agreements may
be asserted at any time before the date which shall be) two years following the
Closing; provided, however, that (i) the representations and warranties set
forth in Sections 4.15, 4.20, 4.27, shall survive until the expiration of the
applicable statute of limitations (with extensions), with respect to the matters
addressed in such sections, and (ii) the representation of good and marketable
title to the Assets, set forth in Section 4.4, will survive for four years
following the Closing. Each party hereto shall be entitled to rely upon the
representations and warranties of the other party set forth in this Agreement.
The termination of the representations and warranties provided herein shall not
affect the rights of a party in respect of any Claim made by such party in a
writing received by the other party prior to the expiration of the applicable
survival period provided herein.

     10.4 Indemnifications.
          ---------------- 

                                       44
<PAGE>
 
          (a) By Seller. Seller shall indemnify, save and hold harmless Buyer,
              ---------                                                       
its affiliates and subsidiaries, and its and their respective Representatives,
from and against any and all costs, losses (including without limitation
diminution in value), Taxes, Liabilities, obligations, damages, lawsuits,
deficiencies, claims, demands, and expenses (whether or not arising out of
third-party claims), including without limitation interest, penalties, costs of
mitigation, losses in connection with any Environmental Law (including without
limitation any clean-up or remedial action), lost profits and other losses
resulting from any shutdown or curtailment of operations, damages to the
environment, attorneys' fees and all amounts paid in investigation, defense or
settlement of any of the foregoing (herein, "Damages"), incurred in connection
                                             -------
with, arising out of, resulting from or incident to (i) any breach of any
representation or warranty or the inaccuracy of any representation, made by
Seller in or pursuant to this Agreement; (ii) any breach of any covenant or
agreement made by Seller in or pursuant to this Agreement; (iii) any Excluded
Liability; or (iv) any Liability imposed upon Buyer by reason of Buyer's status
as transferee of the Business or the Assets, other than the Assumed Liabilities.

          The term "Damages" as used in this Section 10.4 is not limited to
matters asserted by third parties against Seller or Buyer, but includes Damages
incurred or sustained by Seller or Buyer in the absence of third party claims.
Payments by Buyer of amounts for which Buyer is indemnified hereunder, and
payments by Seller of amounts for which Seller is indemnified, shall not be a
condition precedent to recovery. Seller's obligation to indemnify Buyer, and
Buyer's obligation to indemnify Seller, shall not limit any other rights,
including without limitation rights of contribution which either party may have
under statute or common law.

          (b) By Buyer. Buyer shall indemnify and save and hold harmless Seller,
              --------                                                          
its affiliates, subsidiaries and Representatives from and against any and all
Damages incurred in connection with, arising out of, resulting from or incident
to (i) any breach of any representation or warranty or the inaccuracy of any
representation, made by Buyer in or pursuant to this Agreement; (ii) any breach
of any covenant or agreement made by Buyer in or pursuant to this Agreement; or
(iii) from and after the Closing, any Assumed Liability.

          (c) Defense of Claims. If a claim for Damages (a "Claim") is to be
              -----------------                             -----
made by a party entitled to indemnification hereunder against the indemnifying
party, the party claiming such indemnification shall, subject to Section 10.3,
give written notice (a "Claim Notice") to the indemnifying party as soon as
                        ------------
practicable after the party entitled to indemnification becomes aware of any
fact, condition or event which may give rise to Damages for which
indemnification may be sought under this Section 10.4. If any lawsuit or
enforcement action is filed against any party entitled to the benefit of
indemnity hereunder, written notice thereof shall be given to the indemnifying
party as promptly as practicable (and in any event within 15 calendar days after
the service of the citation or summons). The failure of any indemnified party to
give timely notice hereunder shall not affect rights to indemnification
hereunder, except to the extent that the indemnifying party demonstrates actual
damage caused by such failure. After such notice, if the indemnifying party
shall acknowledge in writing to the indemnified party that the indemnifying
party shall be obligated under the terms of its indemnity hereunder in
connection with such lawsuit or action, then the indemnifying party shall be
entitled, if it so elects at its

                                       45
<PAGE>
 
own cost, risk and expense, (i) to take control of the defense and investigation
of such lawsuit or action, (ii) to employ and engage attorneys of its own choice
to handle and defend the same unless the named parties to such action or
proceeding include both the indemnifying party and the indemnified party and the
indemnified party has been advised in writing by counsel that there may be one
or more legal defenses available to such indemnified party that are different
from or additional to those available to the indemnifying party, in which event
the indemnified party shall be entitled, at the indemnifying party's cost, risk
and expense, to separate counsel of its own choosing, and (iii) to compromise or
settle such claim, which compromise or settlement shall be made only with the
written consent of the indemnified party, such consent not to be unreasonably
withheld. If the indemnifying party fails to assume the defense of such claim
within 15 calendar days after receipt of the Claim Notice, the indemnified party
against which such claim has been asserted will (upon delivering notice to such
effect to the indemnifying party) have the right to undertake, at the
indemnifying party's cost and expense, the defense, compromise or settlement of
such claim on behalf of and for the account and risk of the indemnifying party;
provided, however, that such Claim shall not be compromised or settled without
the written consent of the indemnifying party, which consent shall not be
unreasonably withheld. In the event the indemnified party assumes the defense of
the claim, the indemnified party will keep the indemnifying party reasonably
informed of the progress of any such defense, compromise or settlement. The
indemnifying party shall be liable for any settlement of any action effected
pursuant to and in accordance with this Section 10.4 and for any final judgment
(subject to any right of appeal), and the indemnifying party agrees to indemnify
and hold harmless an indemnified party from and against any Damages by reason of
such settlement or judgment.

          (d) Cooperation. The indemnified party shall cooperate in all
              -----------                                              
reasonable respects with the indemnifying party and its attorneys in the
investigation, trial and defense of such lawsuit or action and any appeal
arising therefrom; provided, however, that the indemnified party may, at its own
cost, participate in the investigation, trial and defense of such lawsuit or
action and any appeal arising therefrom. The parties shall cooperate with each
other in any notifications to insurers.

          (e) Brokers and Finders. Pursuant to the provisions of this Section
              -------------------                                            
10.4, each of Buyer and Seller shall indemnify, hold harmless and defend the
other party from the payment of any and all broker's and finder's expenses,
commissions, fees or other forms of compensation which may be due or payable
from or by the indemnifying party, or may have been earned by any third party
acting on behalf of the indemnifying party in connection with the negotiation
and execution hereof and the consummation of the transactions contemplated
hereby.

          (f) Limitations.
              ----------- 

              (i)  Neither Buyer nor Seller shall be liable to the other under
     this Section 10.4 for any Damages arising solely from breaches of Buyer's
     or Seller's (as applicable) representations and warranties until the
     aggregate amount otherwise due the party being indemnified exceeds an
     accumulated total of $100,000; provided that once

                                       46
<PAGE>
 
     the amount of a party's Damages exceeds $100,000, the indemnifying party
     shall be liable to the indemnified party for the total amount of such
     Damages, including without limitation the first $100,000 of such Damages.

               (ii)  With regard to this Section 10.4, Buyer acknowledges that
     it has read and is familiar with, and hereby waives the benefit of, the
     provisions of California Civil Code Section 1542, which is set forth below:

          "A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR DOES
          NOT KNOW OR SUSPECT TO EXIST IN HIS FAVOR AT THE TIME OF EXECUTING THE
          RELEASE, WHICH IF KNOWN BY HIM MUST HAVE MATERIALLY AFFECTED HIS
          SETTLEMENT WiTH THE DEBTOR."

               (iii) Seller shall not be liable to Buyer with respect to
     breaches of Seller's representations and warranties in excess of the
     Purchase Price.

          (g)  Representatives. No individual Representative of any party shall
               ---------------                                                 
be personally liable for any Damages under the provisions contained in this
Section 10.4. Nothing herein shall relieve either party of any Liability to make
any payment expressly required to be made by such party pursuant to this
Agreement.

     10.5 Bulk Sales. It may not be practicable to comply or attempt to comply
          ----------                                                          
with the procedures of the "Bulk Sales Act" or similar law of any or all of the
states in which the Assets are situated or of any other state which may be
asserted to be applicable to the transactions contemplated hereby. Accordingly,
to induce Buyer to waive any requirements for compliance with any or all of such
laws, Seller hereby agrees that the indemnity provisions of Section 10.4 hereof
shall apply to any Damages of Buyer arising out of or resulting from the failure
of Seller or Buyer to comply with any such laws; provided, however, that the
amount of such Damages shall not be limited by the limitations contained in
Section 10.4(g)(i).

     10.6 Taxes. Seller shall pay, or cause to be paid, when due, California
          -----                                                             
sales tax on the first $1,000,000 of Assets subject to California sales tax sold
to Buyer pursuant hereto. Buyer shall pay, or cause to be paid, when due,
California sales tax on any Assets subject to California sales tax in excess of
$1,000,000 sold to Buyer pursuant hereto.

     10.7 Escrow. If at any time in the two years following the Closing Date,
          ------                                                             
the net worth of Whittaker, as reported in its Form 10-K or 10-Q filed with the
Securities and Exchange Commission, is less than $20.0 million, Whittaker shall
provide a letter of credit in the amount of $2,000,000 to fund potential future
indemnification claims of Buyer. In the event that Whittaker (i) consolidates
with or merges into any other person and is not the continuing or surviving
corporation or entity of such consolidation or merger, (ii) transfers all or
substantially all of its assets to any entity, (iii) assigns, sells or transfers

constitute the entire agreement among the parties pertaining to the subject

<PAGE>
 
each of the parties hereto. No waiver of any term or provision of this Agreement

             ---------------------

together shall constitute one and the same instrument.

     11.7    Expenses. Except as otherwise specified in this Agreement, each
             --------                                                       
party hereto shall pay its own legal, accounting, out-of-pocket and other
expenses incident to this Agreement and to any action taken by such party in
preparation for carrying this Agreement into effect.

     11.8    Invalidity. In the event that any one or more of the provisions
             ----------                                                     
contained in this Agreement or in any other instrument referred to herein,

statement or acknowledgment of the existence of, or reveal publicly the terms,
conditions and status of, the transactions provided for herein, without the
prior written consent of the other party as to the content and time of release
of and the media in which such statement or announcement is to be made;
provided, however, that in the case of announcements, statements,
acknowledgments or revelations which either party is required by law to make,
issue or release, the making, issuing or releasing of any such announcement,
statement, acknowledgment or revelation by the party so required to do so by law
shall not constitute a breach of this Agreement if such party shall have given,
to the extent reasonably possible, not less than two calendar days prior notice
to the other party, and shall have attempted, to the extent reasonably possible,
to clear such announcement, statement, acknowledgment or revelation with the
other party. Each party hereto agrees that it will not unreasonably withhold any
such consent or clearance.

     11.12   Service of Process. Consent to Jurisdiction.
             ------------------------------------------- 

        (a)  Service of Process. Subject to Section 11.13, each party hereto
             ------------------                                             
irrevocably consents to the service of any process, pleading, notices or other
papers by the mailing of copies thereof by registered, certified or first class
mail, postage prepaid, to such party at such party's address set forth herein,
or by any other method provided or permitted under California law.

        (b)  Consent and Jurisdiction. Subject to Section 11.13 of this
             ------------------------                                   
Agreement, each party hereto irrevocably and unconditionally (i) agrees that any
suit, action or other legal proceeding arising out of this Agreement may be
brought in the United States District Court for the Central District of
California or, if such court does not have jurisdiction or will not accept
jurisdiction, in any court of general jurisdiction in the County of Los Angeles,
California; (ii) consents to the jurisdiction or any such court in any such
suit, action or proceeding; and (iii) waives any objection which such
Shareholder may have to the laying of venue of any such suit, action or
proceeding in any such court.

     11.13   Arbitration.
             ----------- 

        (a)  The parties agree to negotiate to resolve any dispute between them
regarding this Agreement. If such negotiations do not resolve the dispute to the
satisfaction of both parties, then the President of Buyer shall meet with the
President of Seller and such representatives as either of them may elect to
resolve the dispute. This meeting shall be a required prerequisite before either
party may seek arbitration for resolution of the dispute.

        (b)  In the event that the parties are unable to resolve such dispute
within 30 days after the meeting between the President of Buyer and the
President of Seller, then the matter shall be referred to the Los Angeles office
of J.A.M.S/ENDDISPUTE for mediation, that is, an informal, non-binding
conference or conferences between the parties in which a neutral mediator will
seek to guide the parties to a resolution of the dispute. The parties shall
agree to the selection of a single mediator from J.A.M.S/ENDDISPUTE, or if they
are unable to agree, at the request of the parties, J.A.M.S/ENDDISPUTE will
assign a mediator with respect to the dispute. Unless otherwise agreed by the
parties, the mediation process will continue for no longer than thirty days, and
will terminate if the mediator determines that there is no possibility of
resolution of the dispute through mediation.

        (c)  If any disputes remain between the parties following the completion
of the two step process set forth above, then all remaining controversies or
claims of any nature whatsoever arising out of or connected with the disputes
shall be resolved by submission to final and binding arbitration administered by
J.A.M.S/ENDDISPUTE, in accordance with the J.A.M.S/ENDDISPUTE Rules of Practice
and Procedure. Arbitration may be initiated by a party to this Agreement by
serving the other parties with notice of the nature of any remaining
controversies or claims and a demand for arbitration. Simultaneously, the party
making the claim shall file a copy of such notice and demand for arbitration at
the Los Angeles, California J.A.M.S/ENDDISPUTE office together with the
appropriate filing fee. The arbitrator shall be selected by the joint agreement
of the parties to such dispute, but if they do not so agree within 20 days after
the date of the notice referred to above, the parties may request that the
Contract Arbitration Administrator at J.A.M.S/ENDDISPUTE furnish a list of three
potential arbitrators. Each party shall then be given 10 days to elect to strike
one name from the list. If only one person remains, then such person shall be
the arbitrator. If both parties strike the same name from the list, the Contract
Arbitration Administrator will appoint one person from the list as the
arbitrator of the dispute. Any award rendered by the arbitrator shall be
specifically enforceable by the parties in a court of law and the decision of
the arbitrator shall be final and binding and there shall be no right of appeal
therefrom, except as otherwise provided by applicable law. To the extent that
arbitration may not be legally permitted with respect to a dispute hereunder,
and the parties to such dispute do not mutually agree to submit such dispute to
arbitration, any party may commence a civil action in a court of appropriate
jurisdiction to resolve disputes hereunder. Notwithstanding the foregoing
arbitration provisions, nothing shall prevent the parties from settling any
dispute by mutual agreement at any time. The fees and expenses of such
arbitration (including reasonable attorneys' fees) or any action to enforce an
arbitration award shall be paid by the party that does not prevail in such
arbitration.
