                                  The Closing


     2.1  Place and Date. The closing of the sale and purchase of the Assets
(the "Closing"), and the assumption of the Assumed Liabilities, shall take place
at the offices of Cooley Godward LLP, One Maritime Plaza, 20th Floor, San
Francisco, California, or such other place upon which the parties may agree, on
the first business day following the date upon which each of the conditions to
closing set forth in Articles 8 and 9 of the Agreement shall have been
satisfied. The day on which the Closing actually occurs is herein sometimes
referred to as the "Closing Date."

     2.2  Purchase Price.

          (a)  On the terms and subject to the conditions set forth in this
Agreement, Buyer agrees to pay to Seller at the Closing an aggregate of U.S.
$61,500,000 and to assume the Assumed Liabilities as provided in Section 2.4.
The Purchase Price shall be paid by the wire transfer of immediately available
funds to such bank account or accounts as are specified by Seller in written
instructions given to Buyer at least three days prior to the Closing.

          (b)  Notwithstanding anything to the contrary contained in this
Agreement, the purchase price is subject to adjustment in accordance with
Section 2.2(c) or (d), as the case may be. Attached hereto as Schedule 2.2(b) is
the April Balance Sheet, as adjusted to reflect the elimination of Excluded
Assets and Excluded Liabilities, the provision of appropriate reserves with
respect to certain assets, and other procedures heretofore agreed upon by Seller
and Buyer

                                       3.
<PAGE>

(the "Adjusted April Balance Sheet"). Promptly following the Closing, Seller and
Buyer shall jointly prepare a balance sheet as of the Closing Date in a manner
consistent with the preparation of the Adjusted April Balance Sheet (the
"Closing Balance Sheet"). If Buyer and Seller disagree with respect to any
matter relating to the preparation of the Closing Balance Sheet, such
disagreement shall be promptly submitted for resolution to a nationally
recognized accounting firm that is acceptable to Seller and Buyer (the
"Accounting Firm"). The determination of the Accounting Firm shall be final and
binding upon Seller and Buyer and the fees and expenses of the Accounting Firm
shall be borne equally by Seller and Buyer.

          (c)  If the net assets reflected on the Closing Balance Sheet are less
than the net assets reflected on the Adjusted April Balance Sheet, Seller will
promptly pay to Buyer the amount of such shortfall by wire transfer of
immediately available funds to such bank account or accounts as Buyer shall
specify in written instructions.

          (d)  If the net assets reflected on the Closing Balance Sheet exceed
the net assets reflected on the Adjusted April Balance Sheet, Buyer will
promptly pay to Seller the amount of such excess, such payment to be made by
wire transfer of immediately available funds to such bank account or accounts as
Seller shall specify in written instructions.

     2.3  Allocation of Purchase Price. The parties agree to allocate the
aggregate of the Purchase Price and the Assumed Liabilities (collectively, the
"Aggregate Purchase Price") among the Assets in accordance with section 1060 of
the Code as mutually agreed to by the parties within 180 days following the
Closing. All such mutually agreed to allocations shall be used by each party in
preparing any filings required pursuant to Section 1060 of the Code or any
similar provisions of state or local law and all relevant income and franchise
tax returns. Neither Buyer nor Seller will take any position before any taxing
authority or in any judicial proceeding that is inconsistent with such mutually
agreed to allocations without the prior consent of the other party. The parties
shall in good faith exercise reasonable efforts to support such reported
allocations in any audit proceedings initiated by any taxing authority.

     2.4  Assumption of Liabilities. Subject to the terms and conditions set
forth herein, at the Closing, Buyer shall assume and agree to pay, honor,
perform and discharge when due (collectively, the "Assumed Liabilities"): (a)
all payment obligations of Seller under all severance agreements as set forth in
Schedule 2.4(a) to the extent such obligations arise by virtue of Buyer's
discharge of any former employee of the Seller any time more than 60 days after
the Closing; (b) all product warranty obligations of Seller relating to the
Business and identified on Schedule 2.4(b); (c) all liabilities and obligations
of Seller to be paid or performed from and after the Closing Date under or
relating to the Contracts included among the Assets and set forth on Schedule
2.4(c) and which are validly assigned to Buyer, other than damages, penalties or
other like liabilities or obligations arising from or as a result of a breach of
any contract by Seller or Seller's failure to satisfy any requirement which it
was required to satisfy on or prior to the Closing; (d) all liabilities and
obligations of Seller relating to or arising out of the operation of the
Business in the ordinary course and reflected on the Closing Balance Sheet, (e)
all liabilities and obligations of Seller relating to or arising out of cost
overruns or adjustments to rates and factors used in pricing work performed or
services provided to customers prior to the Closing; (f) all liabilities and
obligations of Seller relating to or arising out of the lawsuits, claims or
other

                                       4.

matters described in Schedule 2.4(f); and (g) fifty percent (50%) of all other
liabilities and obligations (other than Excluded Liabilities) relating to the

corporate power and authority to carry on the Business as currently conducted
and to own or lease and to operate the properties of the Business. Seller is
qualified to do business and is in good standing in each state of the United

of operations of the Business (a "Material Adverse Effect on the Business").

          (b)  The execution and delivery of this Agreement and all other

will have been, at the time of their respective executions and deliveries, duly
executed and delivered by a duly authorized officer of Seller.

          (c)  This Agreement constitutes the valid and legally binding
obligation of Seller, enforceable in accordance with its terms, except as such
enforceability may be limited by equitable principles and by applicable
bankruptcy, insolvency, reorganization, arrangement, moratorium or similar laws
relating to or affecting the rights of creditors generally.

of this Agreement and all other documents and instruments executed or to be
executed by Seller pursuant to this Agreement, and the consummation of the

partnership or other agreement or other instrument, permit, concession, grant,
franchise or license to which Seller is a party or the Assets or the Business is
subject, the result of which,

the aggregate) have a Material Adverse Effect on the Business, or (c) of any
judgment, order, decree, statute, law, ordinance, rule or regulation applicable
to Seller, the Business or the Assets, the result of which, with respect to
items identified in clause (c), would (either individually or in the aggregate)
have a Material Adverse Effect on the Business or a material adverse effect on

(other than a Permitted Lien) on the Assets.

Schedule 3.4, no consents, licenses, approvals or authorizations of, or
registrations or declarations with, any Governmental Authority, or any third
party, are required to be obtained or made by Seller in connection with the
execution, delivery, performance, validity and enforceability of this Agreement,
other than (a) a filing with the Federal Trade Commission and the Department of
Justice under the HSR Act, and (b) other consents, licenses, approvals,
authorizations, registrations or declarations, where the failure to obtain such

effect on the transactions contemplated hereby.

     3.5  No Violations. Except as set forth on Schedule 3.5, Seller is not in
violation of any term of its certificate of incorporation or bylaws or other
charter documents or, to its knowledge, any mortgage, indenture, instrument or
agreement relating to indebtedness for borrowed money or of any judgment, decree
or order which names Seller, or of any term of any other Material Contract which
is among the Assets, which violation, either individually or when aggregated
with all other such violations, would have a Material Adverse Effect on the
Business.  Seller is not in violation, of any law, ordinance, rule or
governmental regulation applicable to the Business or any of the Assets, which
violation, either individually or when aggregated with all other such
violations, would have a Material Adverse Effect on the Business.

other agreement or other instrument, permit, concession, grant, franchise,
license, judgment, order, decree, statute, law, ordinance, rule or regulation
applicable to Buyer or any of its properties or assets, the result of which,
with respect to items identified in clause (b) would (either individually or in

Disclosure Schedule, and except as may be necessary to carry out the
transactions contemplated by this Agreement or any transaction contemplated by

Agreement or the Disclosure Schedules, Seller will not, without Buyer's prior

          (b)  conduct the Business in a manner that departs materially from the
manner in which the Business was being conducted prior to the date of this
Agreement;

          (c)  take any action of the type described in Section 3.7(b)(i), (ii),
(iii), (iv), (v), (vi) or (ix);

          (d)  except in the ordinary course and consistent with past practices,
grant or agree to grant any general increase in the rates of salaries or
compensation of its Employees, or any specific increase to any such Employee
whose total increase would be at an annual rate in excess of 10% of such
employee's annual salary or compensation prior to such increase, or any increase
in the pension, retirement or other employment benefits of the Employees; or

          (e)  agree or commit to do any of the foregoing.

     5.2  Access and Information. Seller shall (and shall cause its officers,

                                   ARTICLE 6

                              Covenants Of Buyer

     6.1  Confidentiality. At all times prior to the Closing, Buyer shall hold
in strict confidence, and shall cause each of its Affiliates to hold in strict
confidence, all documents and information obtained with respect to Seller. At
all times prior to the Closing, Buyer shall not permit any of such documents or
information to be improperly utilized or to be disclosed or conveyed to any
other person or entity, and Buyer shall comply in all respects with the
provisions of the Confidentiality Agreement between Seller and Buyer dated
January 26, 2000 (the "Confidentiality Agreement"). Without limiting the
generality of the foregoing, and except as required by law or pursuant to valid
legal process, Buyer shall not contact any customers or employees of Seller
without the prior consent of an officer of Seller.

     6.2  Investigation. In conducting its review of the Business, Buyer shall
not interfere in any material respect with the Business or with the performance
of their duties by Seller's employees. Buyer shall use commercially reasonable
efforts to complete its due diligence within one (1) week of the date of this
Agreement.

     6.3   Insurance. Buyer shall use commercially reasonable efforts to obtain
and continuously maintain, from the Closing Date until the expiration of the
representations, warranties and covenants pursuant to Section 12.1, insurance
policies with respect to the Business and the Assets on terms and with coverage
no less favorable than those maintained by Buyer in connection with Buyer's
other businesses.

     6.4  Employees.

          (a)  Buyer shall offer employment to (i) each Employee listed on
Schedule 3.17 who is actively at work for the Business immediately prior to the
Closing Date ("Active Employees"), and (ii) to each Employee who is not actively
at work on the Closing Date due solely to authorized leave of absence, sick
leave, short or long-term disability leave or military leave and who, within 180
days after the commencement of the leave, returns to active employment
immediately following such absence ("Inactive Employees"). An Employee's date of
hire by Buyer shall, in the case of an Active Employee, be the Closing Date, and
in the case of an Inactive Employee, on the date that such individual first
reports to work with Buyer. Active Employees and Inactive Employees who accept
Buyer's offer of employment and who become employees of Buyer shall be referred
to as "Transferred Employees." Seller agrees to facilitate the transition of the
Employees to Buyer's employment to the extent permitted by law, which
facilitation shall include, without limitation, affording Buyer and its
representatives reasonable opportunities to discuss with the Employees terms and
conditions of employment with Buyer. Seller will not take, or cause any
affiliate to take, any action that would impede, hinder, interfere or otherwise
compete with Buyer's effort to hire any Employee.

          (b)  Buyer shall assume all liabilities of Seller to the Transferred
Employees of the Business with respect to accrued vacation and sick days or
similar days off by means of a credit to such Employee of the Business of an
equal number of accrued days off under Buyer's

                                      18.
<PAGE>

benefit plans (except to the extent Seller does not credit its employees for
such number or type of days under its benefit plans, in which case Buyer shall
pay the Employee of the Business the value of such accrued days off in cash
within 30 days of Closing). Nothing herein shall restrict Buyer in the exercise
of its independent business judgment, as to the terms and conditions under which
such employment with Buyer shall be offered the duration of such offered
employment, the basis on which such offered employment is terminated or the
compensation or benefits offered to Employees of the Business. Nothing herein
shall be deemed to constitute an agreement to employ any Employee of the
Business for any specific length of time. Seller shall be solely responsible for
any and all severance commitments or obligations of Seller (including retention
incentive agreements) existing as of the Closing Date except with respect to
severance obligations (and not any other obligations under any retention
incentive agreements) for Transferred Employees of the Business who are employed
by the Buyer for at least 60 days after the Closing Date.

          (c)  Seller shall be responsible for any continuation of group health
coverage required under Section 4980B of the Code or Sections 601 through 608 of
ERISA with respect to (i) any Employee or any qualified beneficiary (as defined
in Section 4980B of the Code) of any such Employee who incurs a qualifying event
(as defined in Section 4980B of the Code) prior to such Employee's date of hire
by Buyer, including any such qualifying event incurred by reason of the
employee's termination of employment by Seller, and (ii) any Transferred
Employee or any qualified beneficiary (as defined in Section 4980B of the Code)
of any such Transferred Employee who incurs a qualifying event (as defined in
Section 4980B of the Code) after such employee's date of hire by Buyer;
provided, however, that Seller's responsibility for providing coverage for
Transferred Employees and qualified beneficiaries of such Transferred Employees
shall terminate upon the adoption by Buyer of a group health plan under which
Transferred Employees and their qualified beneficiaries are covered. Buyer shall
reimburse Seller for all costs incurred by Seller in covering all Transferred
Employees and qualified beneficiaries of such Transferred Employee under
Seller's group health plan, including, without limitation, applicable premiums
for such coverage and administrative costs associated with such coverage.
Reimbursement payments pursuant to this Section 6.4(c) shall be made on a
monthly basis by Buyer to Seller within ten (10) days following Buyer's receipt
of notice from Seller of the amount due to satisfy Buyer's reimbursement
obligation.

          (d)  Seller acknowledges that on and after the Closing Date the
account balances of Transferred Employees shall be distributable from the Seller
401(k) Plan in accordance with Section 401(k)(10) of the Code. Neither Seller
nor Seller 401(k) Plan shall place any Transferred Employee's plan loan into
default or declare a default with respect to any plan loan so long as such
individual transfers his or her account balance under the Seller 401(k) Plan,
together with the note evidencing the plan loan, to the Buyer 401(k) Plan
through a direct rollover on or as soon as administratively practicable
following the Closing Date. Buyer shall amend the Buyer's 401(k) Plan and Seller
shall and the Seller 401(k) Plan to the extent necessary in order to effectuate
the transactions contemplated under this paragraph (d). Seller and Buyer shall
cooperate with each other (and cause the trustees of the Seller 401(k) Plan and
the Buyer's 401(k) Plan to cooperate with each other) with respect to the
rollover of the distributions to the affected Transferred Employees.

                                      19.
<PAGE>

          (e)  Buyer shall use commercially reasonable efforts to enter into
employment agreements such of the employees listed on Schedule 8.10 as Buyer may
desire within one (1) week of the date of this Agreement.

     6.5  Tax Cooperation and Retention.

          (a)  Buyer and Seller shall each at their own expense cooperate with,
and make available to, each other such tax data and other information as may be
reasonably required in connection with (1) the preparation or filing of any tax
return, election, consent or certification, or any claim for refund or the
preparation of Seller's financial statements, (2) any determinations of

respect of Taxes ("Tax Data"). Such cooperation shall include without limitation
making their respective employees and independent auditors reasonably available
on a mutually convenient basis for all reasonable purposes, including without
limitation, to provide explanations and background information and to permit the
copying of books, records, schedules, workpapers, notices, revenue agent
reports, settlement or closing agreements and other documents containing the Tax
Data ("Tax Documentation"). If a third party is retained in connection with any
review hereunder, the party retaining such third party shall be responsible for
any fees and expenses of such third party.

          (b)  The Tax Data and the Tax Documentation shall be retained until
one year after the expiration of all applicable statutes of limitations
(including extensions thereof); provided, however, that in the event an audit,
examination, investigation or other proceeding has been instituted prior to the
expiration of an applicable statute of limitations the Tax Data and Tax
Documentation relating thereto shall be retained until there is a final
determination thereof (and the time for any appeal has expired).

     6.6  Financing. Buyer shall use commercially reasonable efforts to enter
into binding commitment letters with one or more financial institutions pursuant
to which credit at least equal to 66-2/3% of the Purchase Price shall be
available to Buyer, on terms reasonably acceptable to Buyer for the purpose of
consummating the transactions contemplated hereby within one (1) one week of the
date of this Agreement.

     6.7  LinkSat Receivables. Buyer shall cooperate with Seller in the
collection of the LinkSat Receivables and in connection therewith, Buyer shall
provide Seller reasonable access during normal business hours to (i) all Books
and Records relating to the LinkSat Receivables, and (ii) all employees having
knowledge relating to the LinkSat Receivables or access to the Books and Records
relating thereto. Such reasonable access (A) shall include, without limitation,
any access required in connection with any judicial or arbitration proceedings
relating to the LinkSat Receivables (including without limitation, access for
the purposes of taking depositions, providing testimony and affidavits,
preparing stipulations, interrogatories or motions, and otherwise conducting
discovery) and any copies of such documents as the Seller shall reasonably
request, and (B) shall be provided to Seller free of charge (other than
reasonable travel related expenses for Buyer's employees and reasonable
duplication charges).

                             Restrictive Covenants

     10.1  Non-Competition. Neither Seller or any of its Affiliates shall, for a
period of three years after the Closing Date, directly or indirectly, anywhere
in the United States, separately or together with any other persons, own,
manage, operate, control, invest or acquire an interest in, or otherwise engage
or participate (whether as a proprietor, partner, stockholder, member, director,
officer, employee, consultant, joint venturer, investor, sales representative or
other participant) in any business, activity or enterprise that competes with
any primary aspect of the Business or any primary aspect of the Business
conducted by Buyer or any of its subsidiaries as conducted on the Closing Date
(collectively, "Competitive Activities"); provided that this Section shall not
prohibit the Seller from engaging in any Competitive Activities to the extent
that Seller is acquired by a Person that is engaged or becomes engaged in such
Competitive Activities, or, directly or indirectly, acquires a Person that is
engaged, at the time of such acquisition, in a Competitive Activity or becomes
engaged, after such acquisition, in a Competitive Activity; provided further
that, to the extent such acquired Person becomes engaged in a Competitive
Activity, Seller shall not transfer any know-how relating primarily to a
Competitive Activity to such acquired Person.

     10.2  Non-Solicitation of Employees. Neither Seller or any of its
affiliates shall, for a period of three years after the Closing Date, directly
or indirectly, for itself or on behalf of any other individual or entity,
solicit any Transferred Employee of Buyer or any of its subsidiaries or induce
nor attempt to induce any such employee to leave his or her employment with
Buyer or any of its subsidiaries; provided that this Section shall not be
violated by virtue of any solicitations by recruiters or other agents acting on
behalf of Buyer so long as Buyer does not hire any Transferred Employees so
solicited by such recruiters or agents.

     10.3  Acknowledgments. Seller acknowledges that, in view of the nature of
the Business and the business objectives of Buyer in acquiring the assets and
the goodwill of the Business, and the consideration paid under this Agreement
therefor, the restrictions contained in this Article 10 are reasonably necessary
to protect the legitimate business interests of Buyer and any violation of such
restrictions will result in irreparable injury to Buyer and its subsidiaries for
which damages will not be an adequate remedy. Seller therefore acknowledges
that, if any such restrictions are violated or threatened to be violated, Buyer
shall be entitled, in addition to all other rights and remedies as may be
provided by law, to specific performance, injunctive and other equitable relief
to prevent or restrain a breach of this Agreement, without the necessity of
showing any actual damage or posting bond or furnishing other security.

Agreement; or

           (d)  by written notice of Seller at any time after July 10, 2000, if
the Closing shall not have occurred on or prior to such date; provided, however,

           (a)  Subject to the provisions of Section 12.1 hereof relating to the
survival of representations and warranties and the other limitations contained
herein, from and after the Closing, Seller agrees to indemnify, defend and hold
harmless Buyer and its Affiliates, officers, directors, employees, agents and
stockholders (collectively, the "Buyer Indemnitees") against the net amount of
all claims, losses, liabilities, damages, deficiencies, costs and expenses,
including without limitation, losses resulting from the defense, settlement
and/or compromise of a claim and/or demand and/or assessment, reasonable
attorneys', consultants', accountants' and expert witnesses' fees, costs and
expenses of investigation, and the costs and expenses of enforcing the
indemnification provided hereunder (hereafter individually a "Loss" and
collectively "Losses") incurred by any of the Buyer Indemnitees (after deduction
of the amount of any insurance proceeds recoverable and net of any tax benefit)
and arising out of or relating to: (i) all Excluded Liabilities; (ii) any
misrepresentation or breach of any representation or warranty made by Seller in
this Agreement or any other document and instrument executed or to be executed
pursuant to this Agreement; and (iii) any breach of any covenant, agreement or
obligation of Seller contained in this Agreement. Notwithstanding the foregoing,
damages shall constitute Losses for the purpose of this Section 12.2 only to the
extent of the direct damages incurred (excluding consequential damages, whether
or not foreseeable).

           (b)  Seller shall not be required to indemnify Buyer Indemnitees with
respect to any claim for indemnification resulting from or arising out of
matters described above pursuant to Section 12.2(a)(ii), unless and until the
aggregate amount of all claims against Buyer Indemnitees exceeds two percent
(2%) of the Purchase Price and then only to the extent such aggregate amount
exceeds one percent (1%) of the Purchase Price. Claims thereafter may be
asserted regardless of amount; provided, however, that Seller's maximum
liability to Buyer Indemnitees under this Section 12.2 shall not exceed:

                (1) in the case of Five Year Matters, 100% of the Purchase Price
in the aggregate;

                                      28.
<PAGE>

                (2) in the case of Two Year Matters, 25% of the Purchase Price
in the aggregate for the first year after the Closing Date and 10% of the
Purchase Price in the aggregate thereafter; and

                (3) in the case of all other matters, 20% of the Purchase Price
in the aggregate;

provided, further, that in no event shall Seller's maximum liability hereunder
exceed 100% of the Purchase Price.

     12.3  Indemnity by Buyer. Subject to the provisions of Section 12.1 hereof
relating to the survival of representations and warranties and the other
limitations contained herein, from and after the Closing, Buyer agrees to
indemnify, defend and hold harmless the Seller and each of its Affiliates,
officers, directors, employees, agents and stockholders (collectively, the
"Seller Indemnitees") against the net amount of all Losses incurred by any of
the Seller Indemnitees (after deduction of the amount of any insurance proceeds
recoverable and net of any tax benefit) and arising out of or relating to: (i)
any Assumed Liabilities; (ii) any misrepresentation or breach of any
representation or warranty made by Buyer in this Agreement; and (iii) any breach
of any covenant, agreement or obligation of Buyer contained in this Agreement.
Notwithstanding the foregoing, damages shall constitute Losses for the purpose
of this Section 12.3 only to the extent of the direct damages incurred
(excluding consequential damages, whether or not foreseeable).

     12.4  Defense of Third-Party Actions. If either a Buyer Indemnitee, on the
one hand, or a Seller Indemnitee, on the other hand (the "Indemnitee"), receives
notice or otherwise obtains knowledge of any matter or any threatened matter
that may give rise to an indemnification claim against the other party (the
"Indemnifying Party"), then the Indemnitee shall promptly deliver to the
Indemnifying Party a written notice describing such matter in reasonable detail.
The timely delivery of such written notice by the Indemnitee to the Indemnifying
Party shall not be a condition precedent to any liability on the part of the
Indemnifying Party under this Article 12 with respect to such matter, except,
and only to the extent of, any actual prejudice to the Indemnifying Party
resulting from such failure to make timely delivery. The Indemnifying Party
shall have the right, at its option to assume the defense of any such matter
with its own counsel, but only if the Indemnifying Party simultaneously agrees
to indemnify the Indemnitee for such matter. If the Indemnifying Party elects to
assume the defense of and indemnification for any such matter, then:

           (a)  notwithstanding anything to the contrary contained in this
Agreement, the Indemnifying Party shall not be required to pay or otherwise
indemnify the Indemnitee against any attorneys' fees or other expenses incurred
on behalf of the Indemnitee in connection with such matter following the
Indemnifying Party's election to assume the defense of such matter;

           (b)  the Indemnitee shall make available to the Indemnifying Party
all books, records and other documents and materials that are under the direct
or indirect control of the Indemnitee or any of the Indemnitee's agents and that
the Indemnifying Party considers necessary or desirable for the defense of such
matter;

                                      29.
<PAGE>

           (c)  the Indemnitee shall execute such documents and take such other
actions as the Indemnifying Party may reasonably request for the purpose of
facilitating the defense of, or any settlement, compromise or adjustment
relating to, such matter;

           (d)  the Indemnitee shall otherwise fully cooperate as reasonably
requested by the Indemnifying Party in the defense of such matter; and

           (e)  the Indemnitee shall not admit any liability with respect to
such matter.

If the Indemnifying Party elects not to assume the defense of and
indemnification for such matter, then the Indemnitee shall proceed with
reasonable diligence to defend such matter with the assistance of Cooley Godward
LLP (in the case of the Seller) or Proskauer Rose LLP (in case of the Buyer) or
other counsel reasonably satisfactory to the Indemnifying Party; provided,
however, that the Indemnitee shall not settle, adjust or compromise such matter,
or admit any liability with respect to such matter, without the prior written
consent of the Indemnifying Party, such consent not to be unreasonably withheld
or delayed.

     12.5  Subrogation. To the extent that the Indemnifying Party makes or is
required to make any indemnification payment to the Indemnitee, the Indemnifying
Party shall be entitled to exercise, and shall be subrogated to, any rights and
remedies (including rights of indemnity, rights of contribution and other rights
of recovery) that the Indemnitee or any of the Indemnitee's affiliates may have
against any other person with respect to any Losses, circumstances or matter to
which such indemnification payment is directly or indirectly related. The
Indemnitee shall permit the Indemnifying Party to use the name of the Indemnitee
and the names of the Indemnitee's Affiliates in any transaction or in any
proceeding or other matter involving any of such rights or remedies; and the
Indemnitee shall take such actions as the Indemnifying Party may reasonably
request for the purpose of enabling the Indemnitee to perfect or exercise the
Indemnifying Party's right of subrogation hereunder.

     12.6  Exclusivity. The right of each party hereto to assert indemnification
claims and receive indemnification payments pursuant to this Article 12 shall be
the sole and exclusive right and remedy exercisable by such party with respect
to any breach by the other party hereto of any representation, warranty or
covenant or failure to pay or perform any Assumed Liability or Excluded
Liability, as applicable.

     12.7  Retention of Records. From and after the date of this Agreement,
Buyer and Seller shall preserve all books, records and other documents,
materials and information relevant to the representations, warranties and
covenants set forth in this Agreement for a period of six years following the
date of this Agreement or for such longer period as the rights of the parties
hereunder may exist.

     12.8  No Rescission. Neither Buyer nor Seller shall be entitled to rescind
the purchase of the Business and the Assets by virtue of any failure of any
party's representations and warranties herein to have been true or any breach of
any party's obligations hereunder.

                                      30.
