         2.2.     Earn-Out Payment.
                  -----------------

                  2.2.1 Based on the Gross  Revenues  (as  hereinafter  defined)
earned by the  Company  during  the period  from  January  1, 2001  through  and
including  December 31, 2001 (the "Earn-Out  Period") subject to any offsets for
outstanding  indemnification  obligations  then owed by the  Stockholders to the
Purchaser  pursuant  to  Section  10  hereof,  the  Purchaser  will  pay  to the
Stockholders and Other Stockholders a one-time Earn-Out Payment as follows:  (a)
One  Million  Dollars  ($1,000,000),  if in  the  Earn-Out  Period  the  Company
generates Gross Revenues of at least Seven Million Five Hundred Thousand Dollars
($7,500,000)  and not more than  Eight  Million  Four  Hundred  and  Ninety-Nine
Thousand Dollars ($8,499,000);  or (b) Two Million Dollars  ($2,000,000),  if in
the Earn Out Period the Company  generates  Gross Revenues of Eight Million Five
Hundred Thousand Dollars ($8,500,000) or greater.

                  2.2.2 For purposes of this Agreement,  "Gross  Revenues" shall
be defined as gross sales of the Company less credits,  customary  discounts and
returns.  The Gross  Revenues of the Company  shall be  determined in accordance
with generally accepted accounting principles consistently applied in accordance
with the historical practices of the Company.

                  2.2.3  Within  ninety (90) days after the end of the  Earn-Out
Period,  Purchaser shall deliver to the Stockholders' Group  Representative,  on
behalf of the Stockholders and Other Stockholders, a statement setting forth the
computation and amount of the Gross Revenues for the Earn-Out Period  ("Earn-Out
Statement") and shall pay the Earn-Out Payment,  if any, to the Stockholders and
Other  Stockholders  within  thirty (30) days after the delivery of the Earn-Out
Statement pursuant to Schedule 2.2.3.

                  2.2.4 The Stockholders' Group Representative shall have thirty
(30) days from the date the Earn-Out Statement is delivered to furnish Purchaser
with a letter requesting access to the books and records which the Stockholders'
Group deems  necessary to compute the Gross  Revenues  for the Earn-Out  Period.
Upon receipt of such request, Purchaser shall promptly make available such

                                        2





books  and  records  to  the   Stockholders'   Group   Representative   and  his
representative.   The  Stockholders'   Group  through  the  Stockholders'  Group
Representative  shall have  fifteen  (15) days  after such  access is granted to
furnish  Purchaser  with a letter  setting  forth  those  items  with  which the
Stockholders'  Group disagrees and the reasons for each such  disagreement.  The
parties shall promptly seek to reconcile any such  disagreement.  If the parties
fail to reach an agreement  within ten (10) days of receipt by Purchaser of such
letter,  then a  "Big  Six"  independent  public  accounting  firm  retained  by
Purchaser and  Stockholders'  Group to settle the  disagreement,  shall make its
determination within thirty (30) days after the dispute is submitted to it which
determination  shall  be  conclusive  ("the  Determination").  The  fee  of  the
accounting  firm shall be paid  exclusively  by the  Stockholders'  Group if the
Determination does not result in the payment of greater Earn-Out Payment than as
originally set forth in the Earn-Out Statement. If the Determination does result
in a greater  Earn-Out  Payment,  the fees of the accounting firm shall be borne
exclusively by the Purchaser. The payment of the Earn-Out Payment in dispute, if
any,  ultimately  determined  (pursuant  to the  procedures  set  forth  in this
paragraph)  to be due to the  Stockholders'  Group shall be made within  fifteen
(15) days of the Determination.

         2.3.     Additional Consideration.
                  ------------------------

                  If the Purchaser  consummates an  underwritten  public sale of
its common stock  ("Registered  Stock")  under the  Securities  Act of 1933,  as
amended,  pursuant  to a  Registration  Statement  on  Form  S-1 or S-3  (or any
successor  form),  during the  Earn-Out  Period (the  "Public  Offering")  which
generates net proceeds in an amount equal to or exceeding  Fifty-Million Dollars
($50,000,000)  (the "Net  Proceeds"),  then, in such event, the Stockholders and
Other  Stockholders  shall be entitled to receive from the Purchaser  within ten
(10) business days after the closing thereof and the receipt of the Net Proceeds
by the Purchaser,  the sum of Two Million Dollars  ($2,000,000) (the "Additional
Consideration"),  allocated to the  Stockholders  and Other  Stockholders as set
forth on Schedule 2.3. Solely in the discretion of the Purchaser,  the Purchaser
may  elect to pay the  Additional  Consideration,  in  whole or in part,  by the
delivery to the Stockholders and Other Stockholders of unregistered common stock
of the  Purchaser,  valued at a price per share  equal to the price per share of
the Registered Stock sold in the Public Offering.  The payment of the Additional
Consideration  shall be subject to any offsets for  outstanding  indemnification
obligations then owed by the  Stockholders to the Purchaser  pursuant to Section
10 hereof.

          and 4.15(b) hereto and all amendments  thereto and any waivers granted
          thereunder (the  "Scheduled  Contracts").  Except as specifically  set

          modification or cancellation of any of the Scheduled  Contracts or for
          the imposition of any penalty or security  interests  thereunder.  The
          Company  enjoys  good  working   relationships   under  all  Scheduled
          Contracts,  and no unresolved  disputes are pending or, to the best of
          the  Stockholders's  knowledge,  threatened under or in respect of any

                  Except as described in Schedule  4.15  hereto,  all  Scheduled
Contracts  described  in  such  Schedule  4.15  are  valid  and  enforceable  in
accordance with their respective terms, except as the enforcement thereof may be
subject to or limited by bankruptcy, insolvency,  reorganization,  moratorium or
other laws  affecting  the  enforcement  of creditors'  rights  generally now or
hereafter in effect and subject to the  application of equitable  principles and
the  availability  of equitable  remedies;  and there is not,  under any of such
documents or agreements or any  obligation,  or covenant or condition  contained
therein,  any existing default by the Company, to the Stockholders's  knowledge,
by any other  party,  or any event which with  notice,  lapse of time,  or both,
would constitute a default and which would have a material adverse effect on the
continued operation of the Company or its business.

restrictions of any kind, and no licenses for the use of any of such rights have
been  granted  by the  Company  to any third  parties,  except as  reflected  in
Schedule 4.16 attached hereto. All of such rights are valid,  enforceable and in
good standing, and are sufficient and appropriate for the conduct of business of
the Company as currently  conducted or as  contemplated  in its plans for future
activities.  The sale of the Stock to the Purchaser and the  consummation of the
other transactions  contemplated  hereby will not adversely affect any rights in
the Intellectual  Property of the Company.  The operation of the business of the
Company  does not  infringe in any way on or  conflict  with any  registered  or
unregistered patent, trademark,  trade name, copyright,  Trade Secret, contract,
license or other right, of any person, and the Company does not license any such
right from others except as set forth on Schedule  4.16. No claim is pending or,
to the  knowledge of the  Stockholders,  threatened  or has been made within the
past five  years,  to the effect  that any such  infringement  or  conflict  has
occurred.  No other Intellectual  Property other than those owned or licensed by
the Company are  required by it for its  business as  presently  conducted.  The
Stockholders have no knowledge of any infringement by any third parties upon any
of  the  Intellectual  Property.  True,  correct  and  complete  copies  of  all

all riders and amendments  thereto.  Such policies are in full force and effect,
and all premiums due thereon  have been paid.  The Company have  complied in all
material  respects  with the  provisions  of such  policies.  No notice has been
received  canceling  or  threatening  to cancel or refusing to renew any of such
insurance.  The rights of the insured under such policies will not be terminated
or  adversely  affected  by  the  Closing  or  the  consummation  of  the  other
transactions contemplated hereby. To the knowledge of the Stockholders, there is
currently no basis for any insurance  claim by the Company.  The Company has not
created any letters of credit or other funding  obligation  with respect to such
policies.

for, or is a party to any contract with the Company.

(i) any breach or default in the  performance by  Stockholders or the Company of
any  covenant or  agreement  of the  Stockholders  and/or the Company  contained
herein or in any  certificate  delivered  pursuant  hereto;  (ii) any  breach of
warranty or representation made by the Company and/or the Stockholders contained
herein or in any certificate delivered pursuant hereto; (iii) any non-compliance
by the Company with the  California  Corporations  Code in  connection  with the
issuance of options or shares of the Company, including, but not limited to, the
availability of an exemption from registration or otherwise;  (iv) any claims by
third  parties  regarding  the  legitimacy  of the  state or  federal  trademark
registration  and/or  use  by  the  Company  of  the  name  "TERRASAT"  and  any
derivations thereof; and (v) any and all actions,  suits,  proceedings,  claims,
demands,  judgments,  costs  and  expenses  (including  reasonable  legal  fees)
incident to any of the foregoing.  Notwithstanding  the foregoing  provisions of
this Section 10.3, no claim for indemnification shall be made by Purchaser under
this  Section  10.3  unless  and until  the  aggregate  amount of all  Losses of
Purchaser  in respect  thereof  shall  exceed  $25,000  exclusive  of any Losses
resulting  from a breach of the  representations  and  warranties  contained  in
Section  4.6.4.  Such  indemnification  shall  be made by (a) an  offset  to the
payment of the Purchase Price pursuant to Section 2.1(b),  the Earn-Out  Payment
payable  pursuant  to  Section  2.2 and  the  Additional  Consideration  payable
pursuant to Section 2.3, and (b) next, by Stockholders  paying cash to Purchaser
to the extent that  Purchaser  is not fully  indemnified  by recourse  under (a)
above.

                  10.3.2  Notwithstanding  anything herein to the contrary,  the
Company's  obligations  under Section 10.3.1 shall  terminate  forever as of the
Closing  Date  and,  accordingly,  the  Stockholders  shall  have  no  right  of
contribution  against the Company in the event of any claim for  indemnification
by the Purchaser hereunder after the Closing.

         10.4.    Indemnification by Purchaser.
                  ----------------------------

                  Purchaser  agrees to indemnify and hold harmless  Stockholders
and  the  Company,  its  affiliates,  its  respective  officers,  directors  and

                                       29





by or arise out of: (i) any breach or default in the performance by Purchaser of
any  covenant  or  agreement  of  the  Purchaser  contained  herein  or  in  any
certificate   delivered  pursuant  hereto;   (ii)  any  breach  of  warranty  or
representation  made  by  Purchaser  contained  herein  or  in  any  certificate
delivered  pursuant hereto;  and (iii)any and all actions,  suits,  proceedings,
claims, demands, judgments, costs and expenses (including reasonable legal fees)
incident to any of the foregoing.  Notwithstanding  the foregoing  provisions of
this Section 10.3, no claim for indemnification shall be made by Stockholders or
the Company under this Section 10.4 unless and until the aggregate amount of all
Losses of Stockholders  and the Company in respect thereof shall exceed $25,000.
Such indemnification shall be made by Purchaser paying cash to Stockholders.

         10.5.    Defense by Indemnifying Parties.
                  -------------------------------

                  (a) An Indemnified  Party shall notify the Indemnifying  Party
of any claim of such Indemnified Party for indemnification  under this Agreement
within  thirty (30) days of the date on which the  Stockholders  or an executive
officer of  Purchaser,  as the case may be, first becomes aware of the existence
of such claim whether such claim would be subject to the $25,000  limitation set
forth in Sections  10.3 and 10.4.  Such notice shall  specify the nature of such
claim in reasonable detail and the Indemnifying  Party shall be given reasonable
access to any  documents  or  properties  within the control of the  Indemnified
Party as may be useful in the  investigation  of the basis for such  claim.  The
failure to so notify the Indemnifying  Party within such thirty-day period shall
not  constitute  a waiver of such claim  (provided  that it does not  materially
interfere with the right of the Indemnifying Party to defend such action) but an
Indemnified  Party shall not be entitled  to receive  any  indemnification  with
respect to any Loss that  occurred  as a result of the failure of such person to
give such notice.

     In the event any Indemnified Party is entitled to indemnification hereunder
based upon a claim asserted by a third party,  the  Indemnifying  Party shall be
given prompt notice thereof,  in reasonable detail. The failure to so notify the
Indemnifying  Party  shall  not  constitute  a  waiver  of  such  claim  but  an
Indemnified  Party shall not be entitled  to receive  any  indemnification  with
respect to any Loss that  occurred  as a result of the failure of such person to
give such notice. The Indemnifying Party shall have the right (without prejudice
to the right of any  Indemnified  Party to  participate  at its expense  through
counsel of its own  choosing) to defend or  prosecute  such claim at its expense
and  through  counsel  of its own  choosing  if it gives  written  notice of its
intention to do so not later than twenty (20) days  following  notice thereof by
the  Indemnified  Party or such  shorter  time  period as  required  so that the
interests  of the  Indemnified  Party would not be  materially  prejudiced  as a
result of its failure to have received such notice;  provided,  however, that if
the  defendants  in any action shall include both an  Indemnifying  Party and an
Indemnified Party and the Indemnified Party shall have reasonably concluded that
counsel selected by the Indemnifying Party has a conflict of interest because of
the availability of different or additional  defenses to the Indemnified  Party,
the  Indemnified  Party  shall  have the right to  select  separate  counsel  to
participate  in the defense of such action on its behalf,  at the expense of the
Indemnifying  Party. If the  Indemnifying  Party does not so choose to defend or
prosecute  any such claim  asserted by a third  party for which any  Indemnified
Party would be entitled to indemnification hereunder, then the Indemnified Party
shall be entitled to recover from the  Indemnifying  Party,  on a monthly basis,
all of its attorneys' reasonable fees and other costs and expenses of litigation
of any nature whatsoever incurred in the defense of such claim. If the

y:\wpwin60\herley\agmts\terrasat.vo3
                                       30





Indemnifying Party assumes the defense of any such claim, the Indemnifying Party
will hold the  Indemnified  Party  harmless from and against any and all damages
arising  out of any  settlement  approved  by  such  Indemnifying  Party  or any
judgment  in  connection  with such  claim or  litigation.  Notwithstanding  the
assumption of the defense of any claim by the Indemnified Party pursuant to this
Section  10.5(a),  the  Indemnifying  Party  shall have the right to approve the
terms of any  settlement of a claim (which  approval  shall not be  unreasonably
withheld).

                  (b) The  Indemnifying  Party and the  Indemnified  Party shall
cooperate in furnishing evidence and testimony and in any other manner which the
other  may  reasonably  request,  and  shall  in all  other  respects  have  any
obligation of good faith dealing,  one to the other,  so as not to  unreasonably
expose  the  other to an undue  risk of loss.  The  Indemnified  Party  shall be
entitled to reimbursement for out-of-pocket  expenses  reasonably incurred by it
in  connection  with such  cooperation.  Except for fees and  expenses for which
indemnification is provided pursuant to Section 10.3 or 10.4 hereof, as the case
may be, and as provided in the preceding sentence, each party shall bear its own
fees and expenses incurred pursuant to this Section 10.5(b).

         10.6.    Remedies Exclusive.
                  ------------------

                  Subject to the last  sentence of this Section  10.6,  from and
after the Closing  Date,  the rights and remedies  under  Sections 10.3 and 10.4
hereof shall be deemed to be  exclusive  of all other  rights and remedies  that
would  otherwise  be available  to the parties  hereto.  No course of dealing by
either party,  or any delay or omission of either party in exercising any rights
or  remedies  under this  Agreement  shall  operate as a waiver of such right or
remedy. Notwithstanding the foregoing, each of the parties hereto shall have the
right to enforce their  respective  rights hereunder by an action or actions for
specific performance, injunction or other appropriate equitable remedies.

         10.7.    Special Provisions Relating to Environmental Matters.
                  ----------------------------------------------------

                  10.7.1 As used in this Agreement,  "Environmental Liabilities"
means:  (i) all claims,  judgments,  liabilities,  damages,  losses,  penalties,
fines,  (including strict  liability),  encumbrances or liens, in each case with
respect to claims  arising in any manner  whatsoever out of the violation of any
Environmental  Laws  by the  Company  or the  breach  of  any  covenants  or the
inaccuracy of the  representations of the Stockholders  pursuant to Section 4.23
of this  Agreement  ("Pre-  Closing  Liability  Conditions"),  and the costs and
expenses of  investigation  and  defense of any such claim,  as well as any good
faith settlement thereof;  (ii) damages to third parties for personal injury, or
injury  to  property  or  natural  resources  arising  from  or  related  to the
existence,  creation or occurrence of the Pre-Closing Liability Conditions;  and
(iii) fees  incurred for the services of  attorneys,  consultants,  contractors,
experts,  laboratories  and all other  costs  incurred  in  connection  with the
investigation or remediation arising from or related to the existence,  creation
or occurrence of the Pre- Closing Liability  Conditions,  to the extent required
by paragraph (e) below.

                  10.7.2 For the purposes  hereof,  "third party" means a person
other than:  (i) one of the parties to this  Agreement or (ii) an heir,  estate,
assign, successor, parent or affiliate corporation, of subsidiary corporation of
one of the parties to this Agreement.



                                       31





                  10.7.3 In accordance with the procedures set forth  previously
in this Section 10, the Stockholders agree to indemnify,  defend,  reimburse and
hold  harmless  the  Purchaser  from  and  against  any  and  all  Environmental
Liabilities.  The Purchaser  hereby waives any and all other claims  against the
Stockholders under any Environmental Laws or common law.

                  10.7.4  In  addition,  the  Stockholders  shall,  at their own
expense, but with counsel approved by the Purchaser defend all claims, suits and
administrative  proceedings  relating to  Environmental  Liabilities and pay and
discharge, when and as the same become due, any and all judgments,  settlements,
penalties or other sums due against the Purchaser,  but in each case only to the
extent relating to Environmental  Liabilities.  The Stockholders  shall keep the
Purchaser  apprised  of the  status of all such  claims,  suits,  administrative
proceedings and negotiations and provide to the Purchaser copies of all relevant
documents and legal papers pertaining thereto.

                  10.7.5 The Stockholders  shall, at their sole cost and expense
but only to the  extent  relating  to the  Environmental  Liabilities,  take all
actions  to  remediate  that  are  required  or  reasonably  necessary  to  meet
Environmental  Laws, but only to the extent that such remediation is required as
a result of Environmental  Liabilities  ("Environmental Work"). The Stockholders
shall proceed diligently with such investigatory and remedial actions,  provided
that in all cases,  such  actions  shall be in  accordance  with all  applicable
requirements of governmental  entities. Any such actions shall be performed in a
good, safe and workmanlike  manner.  The Stockholders  shall promptly provide to
the  Purchaser  copies of testing  results and  reports  that are  generated  in
connection with the above activities.

                  10.7.6  Notwithstanding  anything herein to the contrary,  the
indemnification  obligations of the Stockholders  pursuant to this Section 10.7,
shall survive for so long as permitted by law.

11.      Miscellaneous.

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

                  The Purchaser and the Stockholders  each  irrevocably  consent
that any legal action or proceeding against any of them under, arising out of or
in any manner  relating to, this  Agreement or any other  document  delivered in
connection  herewith,  must be brought only in a federal or state court situated
either in the  Commonwealth  of  Pennsylvania  or in the State of New York.  The
Purchaser and the  Stockholders by the execution and delivery of this Agreement,
expressly and irrevocably consent and submit to the personal jurisdiction of any
of  such  courts  in any  such  action  or  proceeding.  The  Purchaser  and the
Stockholders  further  irrevocably  consent  to the  service  of any  complaint,
summons,  notice or other  process  relating to any such action or proceeding by
delivery  thereof to it by hand or by any other  manner  provided for in Section
11.3. The Purchaser and the Stockholders  hereby expressly and irrevocably waive
any claim or defense in any such action or proceeding  based on any alleged lack
of personal jurisdiction,  improper venue or forum non convenient or any similar
basis.  Nothing in this  Section  shall affect or impair in any manner or to any
extent the right of the  Purchaser to commence  legal  proceedings  or otherwise
proceed against the  Stockholders in any jurisdiction or to serve process in any
manner permitted by law.

provision  of the  covenant  not to  compete,  shall be held or  deemed to be or
shall,  in fact, be  inoperative or  unenforceable  as applied in any particular
case because it conflicts with any other  provision or provisions  hereof or any
constitution or statute or rule of public policy, or for any other reason,  such
circumstances  shall not have the effect of rendering  the provision in question
inoperative or unenforceable in any other case or circumstance,  or of rendering
any other provision or provisions  herein  contained  invalid,  inoperative,  or
unenforceable to any extent whatever. The invalidity of any one or more phrases,
