Section 406 or 407 of ERISA or Section 4975 of the Code.

terminated pursuant to Article 11, neither Seller nor Whittaker shall directly
or indirectly, through any director, officer, agent, financial adviser or
otherwise, solicit, initiate or encourage submission of proposals or offers from
any person relating to any acquisition or purchase of all or a substantial
portion of the Assets or the Business in any form or any equity interest in the
Seller to the extent it would impair the closing of the transactions
contemplated hereunder.  Except in connection with the proper discharge, with
the advice of counsel, by the directors of Seller or Whittaker of their
fiduciary duties under applicable law, neither Seller nor Whittaker shall
participate in any negotiations regarding, or furnish to any other person any

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

          (i) has spent, and will be required to spend, substantial time and

  prospects of the Business;

  expenses in connection with such examination, the preparation of this
  Agreement and the accomplishment of the transactions contemplated hereunder;
  and

          (iii)  will be unable to evaluate and, possibly, make investments in
  or acquire other entities, as an alternative to the Assets and the Business,
  due to the limited number of personnel available for the aforesaid purpose and
  the constraints of time.

or indirectly, through any director, officer, agent, financial adviser or
otherwise, solicits, initiates or encourages submission of proposals or offers
from any person relating to any acquisition or purchase of all or a portion of
the Assets or the Business in any form or any equity interest in the Seller, to
the extent it would prevent the closing of the transactions contemplated
hereunder, or if Seller participates in any negotiations regarding, or furnishes
to any other person any information with respect to, or otherwise cooperates in
any way with, or assists or participates in, facilitates or encourages, any
effort or attempt by any other person to do or seek any of the foregoing, then
Buyer shall be entitled to receive, and Seller shall promptly pay to Buyer on
demand, all of the documented expenses of the Buyer reasonably incurred in
connection with the transactions contemplated under this Agreement, including
but not limited to reasonable fees and disbursements of the Buyer's counsel,
accountants, financial advisors and other consultants or agents.  The
obligations to pay such expenses shall survive any termination of this
Agreement.

     The foregoing amounts shall be payable to Buyer notwithstanding that any
action taken by the directors of Seller or Whittaker which may give rise to the
obligation to pay may have been in accordance with the fiduciary duties of the
directors.  The parties acknowledge that the amount to be paid hereunder is to
compensate Buyer for its time, efforts and expenses in connection with this
transaction and is not a penalty.

     5.6. PUBLIC ANNOUNCEMENTS. The parties will cooperate in the issuance of
any press releases or otherwise in the making of any public statements with
respect to the transactions contemplated hereby.  The parties agree that prior
to the Closing Date, except as otherwise required by law, any and all public
announcements or other public communications concerning this Agreement or the
transactions contemplated hereby shall be subject to the approval of all parties
hereto, which approval shall not be unreasonably withheld; provided, however,
that any party may make any public disclosure it believes in good faith is
required by law or regulation, including, without limitation, any disclosures
made necessary by the status of any Affiliate of Seller or Buyer as a public
company (in which case the disclosing party will advise the other party prior to
making the disclosure) and shall, insofar as may be practicable, reflect in such
disclosure substantially all reasonable comments of the other parties.

                          7.   POST-CLOSING AGREEMENTS

     7.1. PROPRIETARY INFORMATION.

      (a) Obligation of Seller and Whittaker.  Each of Seller and Whittaker
          ----------------------------------                               
agrees that following the Closing Date it shall hold in confidence, and use all
reasonable efforts (at least equal to the efforts used to protect Seller's own
confidential or proprietary information) to have all officers, shareholders,
directors and personnel hold in confidence, (a) all knowledge and information of
a secret or confidential nature with respect to the Business and (b) all
financial information regarding Buyer provided in connection herewith and shall
not disclose, publish or make use of the same without the consent of Buyer,
except to the extent that (i) such information shall have become public
knowledge other than by breach of this Agreement by Seller, (ii) to the extent
the same is financial information of Buyer or Superior, such information is
available to Seller or Whittaker from a person other than persons who have
agreed not to disclose, publish or make use of such information or (iii) Seller
or Whittaker is required to disclose such information to comply with applicable
law (provided that prior to any such disclosure Seller shall consult with Buyer
in an effort to minimize any harm to the competitive position of Buyer and/or
the Business arising from such disclosure).

      (b) Obligation of Buyer and Superior.  Each of Buyer and Superior agrees
          --------------------------------                                    
that following the Closing Date it shall hold in confidence all information
regarding Seller or Whittaker other than information regarding the Business or
the Assets, and shall not disclose, publish or make use of the same without the
consent of Seller, except to the extent that (i) such information shall have
become public knowledge other than by breach of this Agreement by Buyer, or by
any other persons who have agreed not to disclose, publish or make use of such
information, (ii) to the extent the same is financial information of Seller or
Whittaker, such information is available to Buyer or Superior from a person
other than persons who have agreed not to disclose, publish or make use of such
information or (iii) Buyer or Superior is required to disclose such information
to comply with applicable law (provided that prior to any such disclosure Buyer
shall consult with Seller in an effort to minimize any harm to the competitive
position of Seller arising from such disclosure).

      (c) Enforcement.  Each of the parties hereto agrees that the remedy at law
          -----------                                                           
for any breach of this Section 7.1 may be inadequate and that upon any breach
the party or parties to whom any obligation of confidentiality is owed under
this Section shall be entitled to seek injunctive relief in addition to any
other remedy it may have.

     7.2. NON-COMPETITION AGREEMENT.

      (a) Obligation of Seller and Whittaker.  For a period of three years after
          ----------------------------------                                    
the Closing Date, each of Seller and Whittaker agrees that it will not, and will
use its best efforts to cause its corporate Affiliates not to, directly or
indirectly, without the prior written consent of the Buyer, engage in any
Competitive Business or recruit or solicit any employee or consultant of the
Business or of the Buyer to discontinue such employment or engagement, seek to
employ or retain any such employee or consultant or cause any business, person,
firm or corporation to seek or solicit the employment or retention of any such
employee or consultant (except in each instance 

                                       30
<PAGE>
 
for the engagement of a consultant as an independent contractor under
circumstances which would not result in competitive harm or disadvantage to the
Business and/or the Buyer). Nothing contained in this Section 7.2(a) shall
prohibit Seller, Whittaker or their Affiliates from owning, in the aggregate, up
to 5% of the issued and outstanding voting stock of a corporation which may be
engaged in any Competitive Business and whose shares are listed for trading on a
national or regional stock exchange or traded on the over-the-counter market.
Nothing contained in this Section 7.2(a) shall prohibit or restrict Seller or
its Affiliates from (i) discharging warranty or similar obligations or
liabilities relating to services performed or products sold prior to the Closing
Date or obligations under licenses not included in the Contracts (including but
not limited to the license agreement among Whittaker, Whittaker Communications,
Inc. and Xyplex, Inc.) or (ii) enforcing their rights under contracts, leases,
licenses, purchase orders, commitments or similar items, which rights have not
been assigned to Buyer.

      (b) Reasonableness.  The parties hereto agree that the duration and
          --------------                                                 
geographic scope of, and the activities restrained by, the non-competition
provisions set forth in this Section 7.2 are reasonable.  If any court
determines that the provisions' duration, geographic scope, activities
restrained or any combination thereof are unreasonable and that the provisions
for that reason or to that extent are unenforceable, the parties agree that the
provision shall remain in full force and effect for the greatest time period, in
the greatest geographic area and with respect to the broadest ranges or types of
activity that would not render it unenforceable.

      (c) Enforcement.  Seller agrees that damages are an inadequate remedy for
          -----------                                                          
any breach of the provisions of Section 7.2(a) and that Buyer, whether or not it
is pursuing any potential remedies at law, shall be entitled to equitable relief
in the form of preliminary and permanent injunctions without bond or other
security upon any actual or threatened breach of this non-competition provision.
If Seller shall violate Section 7.2(a), the duration of the prohibitions
contained in Section 7.2(a) automatically shall be extended for a period equal
to the period during which Seller shall have been in violation of Section
7.2(a).  The covenants contained in Section 7.2(a) are deemed to be material and
Buyer is entering into this Agreement relying on such covenants.

     7.3. SHARING OF DATA.  Seller and Whittaker each shall have the right, for
a period of four years following the Closing Date (or, with respect to tax
matters, such longer period, not exceeding the expiration of limitations periods
with respect thereto, as shall be reasonably necessary), to have reasonable
access to such books, records and accounts, including financial and tax
information, correspondence, production records, employment records and other
similar information as are transferred to Buyer pursuant to the terms of this
Agreement for the limited purposes of concluding its involvement in the Business
prior to the Closing Date and for complying with its obligations under
applicable securities, tax, environmental, employment or other laws and
regulations.  Seller and Whittaker each shall also have the right, for a period
of eighteen months following the Closing Date, to have reasonable access to such
books and records of Buyer as are reasonably necessary for the limited purpose
of enabling Seller or Whittaker to evaluate the notice given by Buyer under the
provisions contemplated by the Escrow Agreement by verifying the collection or
non-collection of Accounts Receivable.  Buyer shall have the right, for a period
of four years following the Closing Date, to have reasonable access to those
books, records and accounts, including financial and tax information,
correspondence, employment 

                                       31
<PAGE>
 
records and other records which are retained by Seller pursuant to the terms of
this Agreement to the extent that any of the foregoing relates to the Business
transferred to Buyer hereunder or is otherwise needed by Buyer in order to
comply with its obligations under applicable securities, tax, environmental,
employment or other laws and regulations.

     7.4. COLLECTION OF ACCOUNTS RECEIVABLE.  Buyer agrees that it shall use its
reasonable efforts (at least equal to the customary efforts of Buyer in
collecting its own accounts receivable) to collect the accounts receivable
included among the Assets prior to asserting any claim against the Escrow
Account with respect to uncollected Accounts Receivable as contemplated in the
Escrow Agreement.  Nothing in this Section 7.4 shall impose upon Buyer any
obligation to retain counsel or commence litigation or other legal proceedings
as a condition to asserting any claim for indemnification.

     7.5. USE OF OFFICE SPACE.

     (a)  Simi Valley.
          ----------- 

      (i) The parties acknowledge that Seller currently occupies the Leased
  Premises located in Simi Valley, California as a sublessee of Whittaker.  The
  Buyer intends to utilize other premises for the conduct of the Business
  conducted at such location but the parties anticipate that a transition period
  will be necessary while Buyer investigates the availability of other premises.
  For a period of ninety days following the Closing Date, Buyer shall be
  entitled to occupy and use, in its conduct of the Business, without charge or
  cost, the Leased Premises located in Simi Valley (or other premises located in
  the building in which the Leased Premises are located, under the conditions
  set forth in subsection (ii) below).  Following the expiration of such ninety
  day period, Buyer shall be entitled, for an additional period of three months,
  to continue to occupy and use such premises in its conduct of the Business at
  a cost equal to the direct out-of-pocket cost to Whittaker for such space of
  $.51 per square foot per month, without markup or additional charge.

      (ii) Seller may at its option request that Buyer vacate the Leased
  Premises and occupy other premises within the same building for the term
  specified in subsection (i) above, provided that (A) Seller makes available to
  Buyer substitute premises within such building containing an equivalent number
  of net usable square feet as the Leased Premises, (B) Seller or Whittaker pays
  all of Buyer's out-of-pocket moving expenses, plus the lost productivity
  suffered by Buyer as a result of any move calculated on the basis of the
  number of billable hours lost multiplied by the applicable billing rates for
  such personnel; provided that the obligation of Seller and/or Whittaker to
  reimburse Buyer for lost productivity shall not exceed (1) $72,000, if Buyer
  determines that the simulation center located at the Leased Premises need not
  be moved from its existing location, or (2) $92,000, if Buyer determines that
  the simulation center should be moved from its existing location.  Buyer shall
  determine whether the simulation center should be moved based on its
  evaluation in the exercise of its reasonable business judgment as to whether,
  following any move, the simulation center will be secure from use by others
  and will afford Buyer's personnel unrestricted access thereto during normal
  business hours.  If Buyer determines that the simulation center should be
  moved, Seller and Buyer will cooperate in determining a new location for the
  simulation center.

                                       32
<PAGE>
 
     (b) St. Louis.  The parties further acknowledge that Seller currently
         ---------                                                        
occupies additional leased premises located in St. Louis, Missouri.  The Buyer
intends to utilize other premises for the conduct of the Business conducted at
such location but the parties further anticipate that a transition period will
be necessary while Buyer investigates the availability of other premises.  For a
period of up to six months following the Closing Date, Buyer shall be entitled
to occupy and use, in its conduct of the Business and without violating the
terms of Seller's lease for the premises, the leased premises located in St.
Louis and shall pay to Seller on a pass-through basis monthly rent in the amount
of  $2,105, representing the rent payable by Seller under its lease for such
premises.

     7.6. FINANCIAL INFORMATION.  Seller and Whittaker agree to assist Buyer and
Superior in developing financial and other information that may be necessary for
the presentation by either Buyer or Superior of historical and pro forma
financial information which it may be required to file or prepare, as a result
of the consummation of the transactions contemplated hereunder, under the
Securities Exchange Act of 1934 and applicable regulations thereunder.  Buyer
and Superior will engage Superior's independent public accountants, Grant
Thornton LLP, to perform necessary audit services in connection with the
development of such financial information.  Buyer and Superior will use their
reasonable efforts to negotiate a fixed fee arrangement with Grant Thornton LLP
for the performance of such audit services.  Seller and Whittaker, on the one
hand and Buyer and Superior, on the other, shall each pay one-half of the fees
and expenses of Grant Thornton LLP payable in connection with its performance of
such services.

     7.7. COMPUTER NETWORK.  The parties acknowledge that Seller's employees are
currently installing a separate computer network for the corporate office of
Whittaker (the "Corporate Network") and that Seller's employees currently
maintain a computer network for the corporate office and other operating units
of Whittaker (the "Company Network").  Buyer agrees to use its reasonable
efforts to (a) complete the installation of the Corporate Network following the
Closing at no cost to Whittaker or its Affiliates and (b) maintain the Company
Network for a period of 30 days after the Closing Date in a manner comparable to
the manner in which Seller currently maintains the Company Network at no cost to
Whittaker or its Affiliates (but not requiring more than 32 man-hours of work
for such maintenance).  In addition, as long as Buyer maintains the Business in
the building located at 1785 Voyager Avenue, Simi Valley, California, Buyer will
forward all electronic mail that it receives for employees of Whittaker or any
of its Affiliates to Whittaker or such Affiliate.

     7.8. USE OF NAME.  Seller and Whittaker acknowledge and agree that from and
after the Closing, Buyer may use the name "Aviant" and "Aviant Information" in
connection with Buyer's performance of the Assumed Liabilities or as reasonable
in connection with the use of the Assets in the operation of the Business, and
further agree that after the Closing, neither Whittaker nor Seller will use such
name other than as necessary in connection with the winding up of Seller's
business

survive the time at which it would otherwise terminate if notice of the
incorrectness or breach shall have been given to the party against whom such
indemnity may be sought prior to such time.

     8.2. SURVIVAL OF COVENANTS.  All covenants made in this Agreement which by
their terms are to be performed in whole or in part after the Closing shall
survive the Closing until they are performed.

                     9.   INDEMNIFICATION AND REIMBURSEMENT

     9.1. INDEMNIFICATION BY SELLER AND WHITTAKER.

      (a) Seller and Whittaker jointly and severally agree to indemnify, defend
and hold harmless Buyer, Superior and any parent, subsidiary or Affiliate
thereof and all directors, officers, employees, agents and consultants of each
of the foregoing from and against any and all Warranty Expenses, and from and
against any and all Damages suffered, incurred or imposed upon such party with
respect to any claim resulting from or relating to any of the following:

          (i)  INTENTIONALLY OMITTED

                                       34
<PAGE>
 
          (ii) failure by Seller or Whittaker to pay and perform promptly when
  due all of its obligations, liabilities and debts related to the Business
  (other than the Assumed Liabilities);

          (iii)  any breach or default prior to the Closing Date by Seller or
  Whittaker under any of the assumed Contracts;

          (iv) failure by Seller to comply with any bulk sales or similar laws
  applicable to the transactions contemplated hereby;

          (v) accounts receivable assigned to Buyer at closing which remain
  uncollected six months after the Closing Date and for which Buyer has not
  recovered the full amount under the provisions of the Escrow Agreement;
  provided, however that in exchange for payment therefor, Buyer shall reassign
  such accounts to Seller; and

          (vi) any other liability (other than an Assumed Liability) respecting
  the Business or any of the Assets which is attributable to services performed,
  products sold, actions taken, or errors or omissions made, by the Seller prior
  to the Closing Date (including without limitation any liability pursuant to
  warranty claims made by present or former customers of the Business relating
  to services provided or goods sold prior to the Closing Date), whether or not
  the premise upon which liability is asserted became manifest before Closing or
  the liability was first asserted before Closing.

      (b) Buyer and Superior each agrees that prior to settling with any third
party any individual warranty or errors and omission claim in excess of $10,000
for which indemnity may be sought from Seller or Whittaker hereunder, Buyer will
give ten (10) days' written notice to Seller and Whittaker of the existence and
circumstances of such claim and the amount or value proposed to be paid or given
in settlement thereof, and shall consult with Seller and Whittaker regarding any
objections of Seller or Whittaker to the terms or conditions of such settlement.
If either Seller or Whittaker object to the terms thereof, then it shall have
the right to assume the defense of the claim in the manner set forth in Section
9.3(b) and subject to the conditions set forth therein.

      (c) The parties acknowledge that Buyer shall be entitled to invoke the
provisions of the Escrow Agreement with respect to indemnity claims for items
covered thereby but that the provisions of the Escrow Agreement shall not be
deemed exclusive.

     9.2. INDEMNIFICATION BY BUYER AND SUPERIOR.

      (a) Buyer and Superior jointly and severally shall indemnify, reimburse,
and hold harmless Seller, Whittaker and any parent, subsidiary or Affiliate
thereof and all directors, officers, employees, agents and consultants of each
of the foregoing from and against any and all Damages suffered, incurred, or
sustained by Seller, with respect to any claim resulting from or relating to any
of the following:

                                       35
<PAGE>
 
          (i) any misrepresentation, breach of warranty, or nonfulfillment of
  any agreement or covenant on the part of Buyer or Superior under this
  Agreement or other agreement, document, or instrument delivered pursuant to
  this Agreement or in connection with the transactions contemplated hereby and
  referred to herein or in the Schedules hereto; and

          (ii) the operation of the Business after the Closing (other than those
  arising out of contracts, commitments, or agreements of Seller not assumed by
  Buyer) including, but not limited to, any failure by Buyer to pay and perform
  promptly when due any of the Assumed Liabilities, any breach or default after
  the Closing Date by Buyer under any of the Contracts, Permits or Intellectual
  Property and any other liability respecting the Business or any of the Assets
  that is attributable to services performed, products sold, actions taken or
  errors or omissions made by Buyer after the Closing Date.

     9.3. NOTICE AND DEFENSE OF CLAIMS.

      (a) Except with respect to claims for which Buyer seeks recovery under the
Escrow Agreement and not the provisions of this Article 9 (which shall be
governed by the terms of the Escrow Agreement), an Indemnified Party shall give
prompt written notice in accordance with Section 13.1 to all Indemnifying
Parties of any claim or event known to it for which the Indemnified Party
believes it is entitled to indemnification pursuant to this Article 9, stating
the nature and basis of said claims or events and the amounts thereof, to the
extent known.  In the case of any claim, action or proceeding brought by a third
party (a "Claim"), a copy of any Claim, process or legal pleadings with respect
thereto shall be given promptly (and in any event within ten days) after any
such documents are received by the Indemnified Party.

      (b) The Indemnifying Party shall, at its own expense, be entitled to
participate in and, to the extent that it shall wish, assume the defense of any
such Claim.  If the Indemnifying Party elects to assume control of such defense
or settlement, it shall conduct such defense or settlement by retaining
experienced counsel reasonably satisfactory to the Indemnified Party and in such
event, except as provided below, no compromise or settlement shall be agreed or
made without the Indemnified Party's written consent, which shall not be
unreasonably withheld.  In any case, the Indemnified Party shall have the right
to employ its own counsel and such counsel may participate in such action, but
the fees and expenses of such counsel shall be at the expense of the Indemnified
Party unless the Indemnified Party has reasonably concluded (based upon an
opinion of counsel a copy of which is provided to the Indemnifying Party) that
there may be a conflict of interest between the Indemnifying Parties and the
Indemnified Party in the conduct of the defense of such action.

     Notwithstanding anything in this Section 9.3(b) to the contrary, if with
respect to a Claim, a settlement offer is made by the applicable third party
claimant which would release the Indemnified Party from further liability solely
upon payment of money damages and without requiring admission of any of the
claims asserted in the Claim, the Indemnifying Party notifies the Indemnified
Party in writing of the Indemnifying Party's willingness to accept the
settlement offer and pay the amount called for by such offer and the Indemnified
Party declines to accept such offer, then (i) the Indemnified Party may continue
to contest such Claim, free of any participation 

                                       36
<PAGE>
 
by the Indemnifying Party, and (ii) if the Indemnified Party fails to resolve
such claim (by settlement, a final non-appealable order or otherwise) for an
amount which is less than the amount of the rejected settlement offer, the
amount of any ultimate liability with respect to such 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 actual reasonable out of pocket fees and expenses
incurred by the Indemnified Party relating to such Claim through the date of its
rejection of the settlement offer or (B) the aggregate Damages of the
Indemnified Party with respect to such Claim. If the Indemnifying Party makes
any payment on any 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 Claim.

      (c) If the Indemnifying Party does not elect to assume the defense or
settlement of a Claim as provided above, the Indemnified Party may engage
independent counsel selected by the Indemnified Party to assume the defense and
may contest, pay, settle or compromise any such claim on such terms and
conditions as the Indemnified Party may determine.  The fees and disbursements
of such counsel shall constitute Damages for which indemnification shall be made
hereunder.

      (d) Each Indemnified Party and each Indemnifying Party, as the case may
be, shall be kept fully informed of any Claim at all stages thereof whether or
not such party is represented by its own counsel.

     9.4. COOPERATION.  The parties hereto agree to render to each other such
assistance as they may reasonably require of each other and to cooperate in good
faith with each other in order to ensure the proper and adequate defense of any
claim, action, suit or proceeding brought by any third party.  Where counsel has
been selected by the Indemnifying Parties or by an Indemnified Party, the
Indemnifying Parties or the Indemnified Party, as the case may be, shall be
entitled to rely upon the advice of such counsel in the conduct of the defense.

     9.5. CONFIDENTIALITY.  The parties agree to cooperate in such a manner as
to preserve in full the confidentiality of all confidential business records and
the attorney-client and work product privileges.  In connection therewith, each
party agrees that (a) it will use all reasonable efforts, in any action, suit or
proceeding in which it has assumed or participated in the defense, to avoid
production of confidential business records (consistent with applicable law and
rules of procedure) and (b) all communications between any party hereto and
counsel responsible for or participating in the defense of any action, suit or
proceeding shall, to the extent possible, be made so as to preserve any
applicable attorney-client or work product privilege.

     9.6. TIME PERIOD FOR ASSERTING INDEMNIFICATION.  The indemnification
provided in this Article 9 shall be effective only as of the Closing Date.  A
claim for indemnification pursuant to this Article must be asserted by delivery
of a notice as required in Section 9.3 within the following periods:

                                       37
<PAGE>
 
      (a) Except as provided in subsection (c) below, with respect to claims
based on a breach of any representation or warranty of any party contained
herein, within the survival period for the specific representation or warranty
as determined pursuant to Article 8.

      (b) With respect to claims based upon the nonfulfillment of any covenant
contained in this Agreement or in any agreement or document to be delivered
pursuant to this Agreement, on or prior to the later of (i) the second
anniversary of the Closing Date, (ii) two years after the latest date on which
fulfillment of the covenant is required hereunder or (iii) the expiration of
such longer period, if any, as may be specified with respect to any covenant.

      (c) Claims based on Sections 9.1(a)(ii), (iv) or (vi)  or Section
9.2(a)(ii) may be made at any time.

      (d) With respect to Warranty Expenses or any other claims, on or prior to
the second anniversary of the Closing Date.

     9.7. EXCLUSIVE REMEDIES.

  Except with respect to a violation of Section 5.5, 7.1 or 7.2 or as
contemplated by the Escrow Agreement:

      (a) the remedies provided in Section 9.1 shall constitute the exclusive
remedy against Seller or Whittaker by any party indemnified under Section 9.1
for any claim in connection with this Agreement, including any claim of the type
referred to in Section 9.1(a); and

      (b) the remedies provided in Section 9.2 shall constitute the exclusive
remedy against Buyer or Superior by any party indemnified under Section 9.2 for
any claim in connection with this Agreement, including any claim of the type
referred to in Section 9.2(a).

     9.8. LIMITATIONS.  Notwithstanding the foregoing:

      (a) In no event shall Seller or Whittaker be liable to any Indemnified
Party for Damages pursuant to this Article 9 which, when added to all Damages
paid by Seller and Whittaker in the aggregate exceeds the Purchase Price.

      (b) In no event shall Buyer or Superior be liable to any Indemnified Party
for Damages pursuant to this Article 9 which, when added to all Damages paid by
Buyer and Superior in the aggregate exceeds the Purchase Price.

      (c) Any indemnification by Seller or Whittaker pursuant to Section 9.1
shall not be required unless and until the aggregate amount of all Damages
payable by Seller or Whittaker exceeds $50,000; provided, that once such Damages
exceed such amount, Seller and Whittaker shall indemnify the Buyer and Superior
for all Damages and not merely for Damages in excess of such amount.

                                       38
<PAGE>
 
      (d) Any indemnification by Buyer or Superior pursuant to Section 9.2 shall
not be required unless and until the aggregate amount of all Damages payable by
Buyer or Superior exceeds $50,000; provided, that once such Damages exceed such
amount, Buyer and Superior shall indemnify Seller and Whittaker for all Damages
and not merely for Damages in excess of such amount.

                          10.  TRANSFER AND SALES TAX

     10.1.  PAYMENT.  Buyer shall be responsible for and shall pay all filing
and recording, sales, use and transfer taxes and fees, if any, upon the sale or
transfer of any of the Assets hereunder, but not any income, intangibles or
similar taxes payable by Seller or its shareholder by reason of the transactions
contemplated hereunder.

                         11.  TERMINATION OF AGREEMENT

     11.1.  TERMINATION BY LAPSE OF TIME.  This Agreement shall terminate if the
transactions contemplated hereby have not been consummated by 5:00 p.m., Detroit

Seller) may terminate the Agreement on such date.

     11.2.  TERMINATION BY AGREEMENT OF THE PARTIES.  This Agreement may be
terminated by the mutual written agreement of the parties hereto.  In the event

agreement to terminate.

     11.3.  TERMINATION BY REASON OF BREACH.

          -----------------------                                             
if, as of the Closing Date, there shall have occurred (i) a material breach of

     1.1. SUCCESSORS AND ASSIGNS.  This Agreement shall be binding upon and
inure to the benefit of the parties hereto and their respective successors and
permitted assigns.  No party hereto may assign all or a portion of its rights
and obligations hereunder without the prior written consent of the other party,
except that Buyer may assign all or a portion of its rights and obligations
hereunder to an Affiliate of Buyer whether now existing or hereafter created
(but such assignment will not relieve Buyer of any obligation under this
Agreement) and Seller may after the Closing assign all or a portion of its
rights and obligations hereunder to an Affiliate of Seller whether now existing
or hereafter created (but such assignment will not relieve Seller of any
obligation under this Agreement).  Any assignment in contravention of this
provision shall be void.  Notwithstanding any possible inference herein to the
contrary, none of the parties hereto intends for this Agreement to create any
right or obligation except as between Seller and Whittaker, on the one hand, and
Buyer and Superior, on the other, and no other person shall be treated as a
third-party beneficiary hereof.

     1.2. ENTIRE AGREEMENT; ATTACHMENTS.

      (a) This Agreement (including the Exhibits and Schedules hereto), together
with  the Escrow Agreement any other documents and agreements entered into in
connection herewith and referred to herein or in the Schedules hereto, set forth
the entire understanding among the parties relating to the subject matter
thereof, and supersede all prior agreements, arrangements, understandings,
negotiations or discussions.

      (b) If the provisions of any Schedule or Exhibit to this Agreement are
inconsistent with the provisions of this Agreement, the provisions of the
Agreement shall prevail.  The Exhibits 

                                       41
<PAGE>
 
and Schedules attached hereto or to be attached hereafter are hereby
incorporated as integral parts of this Agreement.

     1.3. AMENDMENT; WAIVER.  This Agreement may be amended only by a written
                           -                                                 
instrument signed by the parties hereto.  No provisions of this Agreement may be
waived except by an instrument in writing signed by the party granting such
waiver.  No failure or delay by any party in exercising any right or remedy
hereunder shall operate as a waiver thereof, and a waiver of a particular right
or remedy on one occasion shall not be deemed a waiver of any other right or
remedy or a waiver on any subsequent occasion.  The consummation of the Closing
shall not constitute a waiver of any covenant, representation or warranty
contained in this Agreement, unless the same is waived by an instrument in
writing signed by the party granting such waiver.

     1.4. EXPENSES.  Except as otherwise expressly provided herein, Buyer and
Superior, on the one hand, and Seller and Whittaker, on the other, shall each
pay its own expenses in connection with this Agreement and the transactions
contemplated hereby.

     1.5. GOVERNING LAW.  This agreement shall be governed by and construed in
accordance with the internal laws of the State of Michigan, without regard to
any choice of law principles which would require the application of the law of
any other jurisdiction.

     1.6. ARTICLE, SECTION AND PARAGRAPH HEADINGS.  The section headings of this
Agreement are for the convenience of the parties only and in no way alter,
modify, amend, limit, or restrict the contractual obligations of the parties.

     1.7. SEVERABILITY.  If any term or provision of this Agreement, which is
not in itself material to the transactions contemplated hereby, or the
application of any such term or provision to any circumstance shall, to any
extent, be invalid or unenforceable, the remainder of this Agreement or the
application to other persons and circumstances shall not be affected thereby and
each term and provision hereof shall be enforced to the fullest extent permitted
by law.

     1.8. COUNTERPARTS.  This Agreement may be executed in one or more
counterparts, each of which shall be deemed to be an original, but all of which
shall constitute one and the same Agreement.
