     the Specified Liabilities) (the "Total Consideration") shall be equal to

     2.5. Adjustment. The Estimated Total Consideration paid to Seller pursuant
to Section 2.4(b) shall be adjusted to equal the Total Consideration payable to
Seller pursuant to Section 2.4(a) as follows: (a) If the Closing Date Net Asset
Value shall be less than the Estimated Net Asset Value, the amount paid as
Estimated Total Consideration shall be reduced by such deficit, on a
dollar-for-dollar basis, and Seller shall pay such amount as set forth in
Section 2.6. (b) If the Closing Date Net Asset Value shall be greater than the
Estimated Net Asset Value, the amount paid as Estimated Total Consideration
shall be increased by such excess, on a dollar-for-dollar basis, and Buyer shall
pay such amount as set forth in Section 2.6. The amount by which the amount paid
as Estimated Total Consideration shall be increased or decreased pursuant to
this Section 2.5 shall be the "Adjustment Amount".

     2.6. Net Assets.

          (a) As promptly as practical after the Closing Date and receipt by
     Buyer of the necessary information, books and accounts, but in no event
     later than twenty (20) days thereafter, Buyer shall cause the preparation
     of, and deliver to Seller, a statement of the Closing Date Net Asset Value
     (the "Statement"), together with Buyer's calculations of the Adjustment
     Amount, and shall be accompanied by the payment of any portion of the
     Adjustment Amount which Seller (or Buyer) does not dispute is owed to Buyer
     (or Seller). Seller shall have the right to cause the preparation of the
     Statement in the event of Buyer's failure to perform its obligation under
     this Section 2.6(a).

          (b) The Statement and Buyer's (or Seller's) calculation of the
     Adjustment Amount shall become final and binding on Seller and Buyer on the
     20th day following the date Buyer (or Seller) delivers the Statement and
     Buyer's (or Seller's) calculation of the Adjustment Amount (the "Dispute
     Deadline Date"), unless prior to the Dispute Deadline Date Seller (or
     Buyer) delivers notice to Buyer (or Seller) of its disagreement. Such
     notice shall set forth all of the disputed items together with proposed
     changes thereto, including an explanation in reasonable detail of the basis
     of proposed changes, and shall be accompanied by the payment of any portion
     of the Adjustment Amount which Seller (or Buyer) does not dispute is owed
     to Buyer (or Seller).

          (c) If Seller (or Buyer) has delivered a timely notice of
     disagreement, then Buyer and Seller shall use their good faith efforts to
     reach written agreement on the disputed items (in which case, such mutual
     agreement shall be conclusive as to the value of the Adjustment Amount). If
     all of the disputed items have not been resolved by Buyer and Seller by the
     30th day following receipt by Buyer (or Seller) of the notice of

                                      -10-

<PAGE>
     disagreement, then the disputed items shall be submitted to the Neutral
     Accountants for binding arbitration within twenty (20) days after the end
     of the foregoing 20-day period. The Neutral Accountants shall complete
     their determination of the Adjustment Amount within fifteen (15) days from
     submission of the dispute, unless Buyer and Seller agree otherwise. The
     fees and expenses of such arbitration shall be borne 50% by Seller and 50%
     by Buyer, except that if the arbitrators determine that either party
     proceeded to arbitration in bad faith, or acted in bad faith during the
     course of the arbitration proceeding, then all expenses of such
     arbitration, plus interest at a rate of 1 1/2% per month on such unpaid
     portion of the Adjustment Amount, calculated from the Closing Date until
     the date of actual payment, shall be paid by the party that is determined
     to have acted in bad faith. For purposes of this provision, a party's
     failure to remit any portion of the Adjustment Amount which such party does
     not, in good faith, dispute is owed to the other party shall be considered
     "bad faith". The determination of the Closing Date Net Asset Value and the
     Adjustment Amount by such arbitration shall be final and binding upon the
     parties. Seller (or Buyer) shall pay the balance of the Adjustment Amount
     not yet paid within five (5) Business Days from the date of determination
     of the Adjustment Amount either by agreement of the parties or by the
     Neutral Accountants.

          (d) The Statement shall be prepared from Seller's books and records in
     accordance with GAAP, applied on a consistent basis.

     2.7. Allocation of Total Consideration. Seller and Buyer agree to allocate
the Total Consideration (together with the Specified Liabilities) for the
Specified Assets and the obligations under the Noncompetition Agreement, as set
forth on Schedule 2.7 (the "Allocation of Total Consideration"). The Allocation
of Total Consideration shall be completed in the manner required by Code Section
1060. Seller and Buyer further agree to comply with all filing, notice and
reporting requirements described in Code Section 1060 and the Treasury
Regulations promulgated thereunder, including the timely preparation and filing
of Forms 8594 based on the Allocation of Total Consideration. Seller and Buyer
hereby agree that they will report the federal, state, foreign and other tax
consequences of the transactions contemplated by this Agreement in a manner
consistent with the Allocation of Total Consideration.

     2.8. Receipts After Closing. After the Closing, Seller may receive funds,
proceeds, contributions, refunds, rebates, payments or receipts that are
attributable to the Specified Assets and are properly allocable to Buyer under
the terms of this Agreement. Seller agrees to remit or cause to be remitted any
of the foregoing to Buyer, within five (5) Business Days of receipt thereof.
Buyer agrees to remit to Seller within five (5) Business Days of receipt
thereof, any funds, proceeds, contributions, rebates, payments or receipts that
are attributable to the Excluded Assets and are properly allocable to Seller
under the terms of this Agreement. If Seller receives any invoices (not used in

invoice directly or remit to Seller within five (5) Business Days of receipt
thereof, the amount of such invoices.

               (ii) Each Specified Contract is a legal and valid agreement,
          arrangement or commitment of Seller to which it is a party,
          enforceable against Seller in accordance with its terms and is a legal

          thereto, enforceable against such party in accordance with its terms,

          insolvency or other similar laws affecting creditors' rights generally
          and except where enforceability is subject to the application of
          equitable principles or remedies or as would not have, individually or

          entered into by such Customer. True and complete copies of the
          Specified Contracts have been delivered to or otherwise made available

          breach, violation or default, or but for a requirement that notice be
          given or that a period of time elapse or both, would be in breach,
          violation or default, under any Specified Contract which defaults, in
          each case, individually, or in the aggregate, would reasonably be
          expected to have a Material Adverse Effect with respect to the
          Business. Seller has complied in all material respects with all
          commitments and obligations under each such Specified Contract to

     prior review by the non-filing party, or (ii) any such filing made is not
     one of Seller's Consents and Approvals (if the filing is made by Seller) or
     one of Buyer's Consents and Approvals (if the filing is made by Buyer) the
     party making such filing shall reimburse the non-filing party promptly on
     demand all out-of-pocket costs and expenses (including attorneys' fees)
     reasonably incurred by the non-filing party in connection with monitoring
     such filing and any Proceeding related thereto (including, if deemed
     necessary or appropriate by the non-filing party, intervening with respect
     to such Proceeding).

          (b) Third Party Consents. Each party shall use its commercially
     reasonable efforts (but shall not be required to incur any material cost or
     liabilities) to assist the other party in obtaining any consent of third
     parties necessary or advisable in connection with the transactions
     contemplated by this Agreement. Without limiting the generality of the
     foregoing, Seller shall use commercially reasonable efforts to assist Buyer
     in obtaining any Permits necessary or advisable to assign to Buyer the
     Specified Contracts and otherwise to consummate the transactions
     contemplated hereby.

     7.3. Public Announcements. Seller and Buyer agree that after the Effective
Date, each party shall have the right to issue a press release with respect to
this Agreement and the transactions contemplated hereby substantially in the
form of Exhibit B. Thereafter Buyer and Seller and their respective Affiliates
shall have the right from time to time to issue any press release or make any
public statement regarding the transactions contemplated hereby, subject (in
each case where the content of such the press release or public statement is not
substantially in the form of Exhibit B) to the prior approval of the other party
except as may be, in the sole judgment of the party desiring disclosure,
required or appropriate under Applicable Law.

     7.4. Amendment of Schedules. Each party agrees that, with respect to the
representations and warranties of such party contained in this Agreement, such
party shall have the continuing obligation until the Closing to supplement or
amend promptly the Schedules with respect to any matter hereafter arising or
discovered which, if existing or known as the date of this Agreement, would have
been required to be set forth or described in the Schedules; provided, however,
that for the purposes of determining whether the Closing Conditions have been
fulfilled, the Schedules shall be deemed to include only that information
contained therein on the Effective Date and shall be deemed to exclude all
information contained in any supplement or amendment thereto.

     7.5. Fees and Expenses. Except as otherwise expressly provided in this
Agreement, all fees and expenses, including fees and expenses of counsel,
financial advisors, and accountants incurred in connection with this Agreement
and the transactions contemplated hereby shall be paid by the party incurring
such fee or expense, whether or not the Closing shall have occurred.

     7.6. Transfer Taxes. All sales, use, transfer, filing, recordation,
registration and similar Taxes and fees arising from or associated with the
transactions contemplated hereunder,

                                      -23-

<PAGE>

whether levied on Buyer or Seller shall be borne by Buyer. Seller and Buyer
shall file all necessary documentation with respect to, and Buyer shall make all
payments of, such Taxes and fees on a timely basis or, if Seller makes such
payments, Buyer shall reimburse Seller within five (5) Business Days after
receipt of notification from Seller. Within thirty (30) Business Days after
Closing, Buyer shall provide to Seller appropriate state exemption certificates
that may be applicable to the transactions contemplated hereunder.

     7.7. Casualty Loss. Notwithstanding anything to the contrary in this
Agreement, in the event of damage by fire or other casualty to the Specified
Assets prior to Closing, this Agreement shall remain in full force and effect,
there shall be no reduction in the Total Consideration and no failure of a
condition to Closing shall be deemed to exist by virtue of such event if, in any
such event Seller, at its option, (i) repairs such damage (which Seller shall
have no obligation to do), (ii) collects (and when collected pays over to Buyer)
any insurance claims related to such damage, or (iii) assigns to Buyer such
insurance claims; provided, however, that if such loss has a Material Adverse
Effect with respect to Seller or the Business, Buyer may elect, as its option,
to terminate this Agreement. In the event Buyer elects not to terminate this
Agreement as aforesaid, the foregoing provisions of this Section shall apply,
and the Closing Date shall be delayed until the date on which all necessary
operations have been restored in order that there is no longer a Material
Adverse Effect with respect to Seller or the Business, but such date shall not
be later than the relevant date set forth in Section 10.1(b).

     7.8. Insurance. If any claims are made or losses occur prior to the Closing
Date that relate solely to the Specified Assets and such claims, or the claims
associated with such losses, may be made against or under the policies retained
by Seller or its Affiliates after the Closing, then Seller shall use its
reasonable commercial efforts so that Buyer can file, notice, and otherwise
continue to pursue these claims pursuant to the terms of such policies. Seller
and its Affiliates shall be reimbursed by Buyer (or otherwise indemnified and
held harmless) for any losses or other costs incurred by Seller or its
Affiliates (including by way of any reduction in, or loss of, available
insurance to cover other insurable losses or associated expenses of Seller or
its Affiliates) arising out of Buyer pursuing these claims under such policies.

     7.9. Confidentiality.

          (a) Seller has had access to, and has gained knowledge with respect to
     the Business and the Specified Assets, and relating to Buyer and its
     Affiliates, and the related trade secrets, financial results and
     information, processes and techniques, plans, research, designs, concepts,
     methods of doing business and information concerning customers and
     suppliers, and other valuable and confidential information, which is not
     generally known to the public (the "Confidential Information"). Seller and
     Buyer acknowledge that unauthorized disclosure or misuse of the
     Confidential Information following the date of this Agreement may cause
     irreparable damage to Buyer. Accordingly, for a period of four (4) years
     commencing on the Effective Date, Seller agrees to hold in strict
     confidence and not disclose to any Person any Confidential Information
     obtained by Seller while Seller was conducting the Business or while Seller
     owned any of the Specified Assets.

                                      -24-

<PAGE>

          (b) Nothing in this Section 7.9 shall prevent Seller from using or
     disclosing any such Confidential Information as counsel to Seller advises
     should be used or disclosed in connection with litigation or pursuant to
     Applicable Law or in the course of a defense of a claim assumed by Seller
     as an Indemnifying Party pursuant to Section 11.3 or, to the extent
     necessary, in the course of collecting any accounts receivable, or in
     connection with a Deferred Contract or as permitted under Section 7.3

          (c) Seller agrees to indemnify and hold harmless Buyer and its
     representatives from and against any Claim arising out of any breach of
     their obligations under this Section 7.9. Seller and Buyer agree that
     because an award of money damages (whether pursuant to the foregoing
     sentence or otherwise) would be inadequate for any breach of this Section
     7.9, any such breach would cause Buyer irreparable harm. Seller also agrees
     that in the event of any breach or threatened breach of this Section 7.9,
     Buyer will also be entitled, without the requirement of posting a bond or
     other security, to equitable relief, including injunctive relief and
     specific performance. The Claim procedures set forth in Section 11.3 shall
     apply with respect to any indemnification sought pursuant to this section.
     If buyer asserts a Claim against Seller under this Section 7.9(c), the
     prevailing party shall be entitled to recover its legal fees and costs from
     the other party.

     7.10. Consents. Without limiting Seller's and Buyer's respective rights
pursuant to Articles VIII or IX with respect to Seller's or Buyer's obligations
to close, in the event Seller or Buyer, as applicable, waives its rights under
Sections 8.3 or 9.3, respectively, and Seller and Buyer elect to proceed with
the Closing notwithstanding the fact that not all Consents and Approvals have
been obtained, the parties further agree that Seller shall retain, until such
time as all Consents or Approvals shall have been obtained, all rights to and
liabilities under any Specified Contract to which any required consent or
approval listed on Schedule 3.4 pertains if such consent or approval has not
been obtained prior to Closing (the "Deferred Contract"). Until the assignment
of the Deferred Contract, (a) Buyer shall continue to use all commercially
reasonable efforts and Seller shall fully cooperate with Buyer to obtain all
required consents or approvals to remove any other impediments to such
assignment, and (b) Seller shall cooperate with Buyer (and Buyer shall cooperate
with Seller) in any arrangement to provide (to the extent permitted without
breach of such Deferred Contract or Applicable Law) Buyer with the benefits and
burdens of such Deferred Contract after the Closing Date to the same extent as
if such Deferred Contract had been assigned to Buyer (such arrangement, an
"Alternative Arrangement"). Seller and Buyer shall agree in good faith as to the
terms of such Alternative Arrangement, which arrangement may consist of an
arrangement pursuant to which Seller subcontracts Buyer to perform under the
Deferred Contracts, substantially in the form of the Subcontract attached hereto
as Exhibit C. If, subsequent to the Closing, Seller shall obtain all required
consents or approvals required to assign any Deferred Contract, the Deferred
Contract for which consent or approval to assign has been obtained shall at that
time be deemed to be conveyed, granted, bargained, sold, transferred, setover,
assigned, released, delivered and confirmed to Buyer and assumed by Buyer,
without need of further action by Seller or of further documentation except for
notice from Seller to Buyer that such consent or approval has been obtained; and
from and after the effective date such Deferred Contract is assigned to Buyer,
(x) no party shall have any further liability under the Alternative Arrangement
related thereto, and (y) the Deferred Contract shall be deemed to be a Specified
Asset and Specified Liability. Seller's obligations pursuant to the
Non-competition Agreement with respect to any Deferred

                                      -25-

<PAGE>

Contract shall be of no effect unless and until Buyer has assumed the benefits
and burdens of such Deferred Contract pursuant to an Alternative Arrangement or
until its assignment.

     7.11. Maintenance of Guaranties and Insurance. Seller agrees that from the
Effective Date and until the earlier to occur of (a) the Closing and (b) the
termination of this Agreement, Seller agrees (i) to keep its insurance policies
described in Schedule 3.13 in force and (ii) not to cancel, and will cause its
Affiliates not to cancel, any of Seller's insurance policies without the prior
written consent of Buyer. Seller shall cause any and all guaranties of any
Affiliate or any other party on behalf of Seller, any insurance coverage or bid,
payment or performance bond, with regard to the Business to be and remain
unchanged and in full force and effect.

     7.12. Employees.

          (a) Promptly after the execution hereof by each of the parties, Buyer
     will offer employment, to be effective on the day immediately succeeding
     the Closing Date, to the Business Employees (as listed on Schedule 3.12
     (A)). Not fewer than five (5) Business Days prior to the Closing Date,
     Buyer will provide Seller with a list of Business Employees who have
     accepted such offer of employment from Buyer as of that date. Effective on
     the Closing Date, Seller will terminate the employment of all such Business
     Employees who have accepted Buyer's offer of employment, and Buyer will
     hire those Business Employees who report to work on the day immediately
     succeeding the Closing Date (such Business Employees, the "Hired Business
     Employees"). Buyer, in its sole discretion, shall set the terms and
     conditions of employment for any Hired Business Employees, including but
     not limited to employee benefits. To the extent permissible under Buyer's
     Benefit Plans, Buyer will offer each Hired Business Employee credit for
     years of service with Seller, in accordance with the terms of, and subject
     to the limitations under, Buyer's Benefit Plans.

          (b) Seller shall be solely liable for any costs or liabilities
     incurred in connection with Seller's continued employment or termination of
     Seller's employees, including any Business Employees who do not accept
     Buyer's offer of employment, and in connection with the termination by
     Seller of the employment of those Business Employees who have accepted
     Buyer's offer of employment, including liabilities for incentive
     compensation, bonus, severance and other benefits. Buyer shall be solely
     liable for any costs or liabilities incurred in connection with the
     employment or termination of Hired Business Employees, including
     liabilities for severance and other benefits, from the day the Hired
     Business Employees are hired by Buyer. Seller shall be fully and solely
     responsible for any costs, expenses, obligations and liabilities, vested or
     non-vested, arising out of the pension or retirement obligations
     attributable to the Seller's employees relating to the period ending on or
     prior to the Closing Date. Seller agrees to indemnify, defend and hold
     Buyer Indemnified Parties harmless from and against all direct or indirect
     costs, expenses or liabilities arising from or relating to claims made by
     or on behalf of the Seller's employees with respect to termination of
     employment by reason of the transactions contemplated by this Agreement,
     including, but not limited to, any claims for improper termination or
     severance payments. Seller agrees to indemnify defend and hold Buyer
     Indemnified Parties harmless from and against, and Buyer agrees to
     indemnify, defend and hold Seller Indemnified Parties harmless from and
     against, any

                                      -26-

<PAGE>

     and all Claims arising out of the other party's employment practices that
     are contrary to Applicable Law (including any unlawful practices by Buyer
     which result in Buyer's failure to hire any Business Employee).

          (c) Seller or, where applicable, Seller's appropriate employee benefit
     plans shall be liable for any claims incurred by the Hired Business
     Employees and their beneficiaries through the Closing Date under Seller's
     employee benefit plans. Buyer or, where applicable, Buyer's appropriate
     employee benefit plans, shall be liable for any claims incurred by the
     Hired Business Employees and their beneficiaries after the Closing Date
     under Buyer's employee benefit plans. For purposes of this Section 7.12(c),
     a claim will be deemed incurred in accordance with the applicable rules
     under each of Seller's and Buyer's benefit plans.

          (d) Subject to the provisions of this Section 7.12, the Hired Business
     Employees shall be eligible to participate in Buyer's medical and other
     welfare plans, as defined in Section 3(1) of ERISA ("Buyer Benefit Plans"),
     in accordance with the terms of such plans.

          (e) Buyer shall be solely liable for any and all claims for severance
     with respect to Hired Business Employees arising out of the termination of
     a Hired Business Employee by Buyer.

          (f) Seller and Buyer hereby agree to utilize the "Standard Procedure"
     set forth in Revenue Procedure 2004-53,2004-34IRB 320, or a corresponding
     future revenue procedure or other administrative pronouncement, with regard
     to the reporting requirements attributable to wages paid or to be paid to
     Business Employees.

          (g) No Hired Business Employee including any beneficiary or dependent
     thereof, or any other Person not a party to this Agreement, shall be
     entitled to assert any claim hereunder.

          (h) Except as otherwise provided in this Section 7.12 or in Article
     XI, where this Section 7.12 requires a party to take any action or perform
     any task, the party obligated to take such action or perform such task
     shall be responsible for all fees, costs and other expenses incurred for,
     and related to, such actions or tasks.

          (i) For a period not to exceed thirty (30) days from the Closing Date,
     Seller shall have the right to use a portion of the office located in the
     city of San Diego, California, located at 1660 Hotel Circle North, for one
     (1) of its employees, in exchange for the payment of the sum of Five
     Hundred and No/100 Dollars ($500) per month, provided, however, that rent
     for partial months shall be prorated per the number of days in which such
     office was used. Either party shall have the right to terminate, in whole
     or in part, its use of such offices upon ten (10) days advance written
     notice to the other party, provided, however, that Buyer shall have the
     right to terminate such lease only in the event Seller's employee's
     presence or behavior becomes detrimental to Buyer's activities, as
     determined in Buyer's reasonable judgment.

                                      -27-

<PAGE>

          (j) Within thirty (30) days from the Closing Date, Buyer shall remove
     certain inventory and forms, included within the Specified Assets,
     currently located in Seller's plant in Hillsboro, Texas.

     7.13. Seller's Warranty Work. At Seller's request and for a period of no
more than five (5) years commencing on the Closing Date, Buyer agrees to perform
Seller's warranty work arising out of Seller's conduct of the Business prior to
the Closing, subject to the conditions set forth below. Seller shall deliver to
Buyer a notice describing in reasonable detail the warranty work to be performed
by Buyer, which notice shall be delivered to Buyer no later than fifteen (15)
Business Days prior to the date any such work must be performed. In addition,
Buyer's obligations to provide such Seller's warranty work are subject to (i)
Buyer's other commitments and obligations (to be determined in Buyer's sole
discretion), or (ii) availability of personnel and material, and shall be
performed at Buyer's then prevailing prices, subject to site- or job-specific
conditions that may affect pricing for such work.

     7.14. Accounts Payable. Seller shall pay its Accounts Payable in accordance
with Seller's normal and reasonable commercial practices. Subject to the final
sentence of Section 2.8, if Buyer receives invoices, bills, statements of other
claims that refer to goods and/or services supplied to Seller prior to the
Closing Date, Buyer will promptly forward them to Seller, and Seller agrees to
pay on a timely basis all such invoices, bills, statements and other claims
forwarded by Buyer. Subject to the final sentence of Section 2.8, after the
Closing Seller may receive invoices, bills, statements and other claims that
refer to goods and/or services supplied to Buyer, Seller shall promptly
forwarded them to Buyer, and Buyer agrees to pay on a timely basis all such
invoices, bills, statements and other claims forwarded by Seller.

          (b) by Seller or by Buyer, if the transactions contemplated by this
     Agreement to take place at the Closing shall not have been consummated by
     February 28, 2006, unless the failure of such transactions to be
     consummated is due to the willful failure of the party seeking to terminate
     this Agreement to perform any of its obligations under this Agreement to
     the extent required to be performed by it prior to or on the Closing Date;

          (c) by Seller or by Buyer, if a material breach or default shall be

Specified Assets after the Closing Date; or (iii) cleanup or remediation
requirement or liability respecting a Release or threatened Release of any
Hazardous Substances to the extent related to the Specified Assets and occurring
after the Closing Date; provided, however that, the right of a Seller
Indemnified Party to be indemnified for a Direct Claim under this Section
11.2(d) is limited to circumstances or events where Seller or any Seller
Indemnified Party is required to undertake the activities giving rise to such
Direct Claim in order to comply with an Environmental Law or, in Seller's
reasonable judgment, to respond to an Environmental Claim; and Buyer shall
reimburse Seller Indemnified Parties for any legal or other expenses reasonably

     indemnified for a Direct Claim under this Section 11.2(c) is limited to
     circumstances or events where Buyer or any Buyer Indemnified Party is
     required to undertake the activities giving rise to such Direct Claim in

     judgment, to respond to an Environmental Claim;

          (d) any Taxes for which Seller is liable under Article XII or any

Seller shall reimburse Buyer Indemnified Parties for any legal or other expenses
incurred by Buyer Indemnified Parties in connection with investigating or
defending any such Claim which is the Claim of a third party as such expenses
are incurred.

     11.3. Claim Notice.

          (a) Indemnified Parties. As used in this Article, the term
     "Indemnified Party" shall mean any Seller Indemnified Party or any Buyer
     Indemnified Party, as the case may be, which is asserting a claim for
     indemnity hereunder. Any party against whom a claim for indemnification is
     asserted by an Indemnified Party pursuant to this Article is referred to
     herein as an "Indemnifying Party." In the event that any Claims are
     asserted against or sought to be collected from an Indemnified Party by a
     Person who is not a Buyer Indemnified Party or a Seller Indemnified Party
     (a "Third Party"), such Indemnified Party shall give prompt written notice
     to the Indemnifying Party of such event ("Claim Notice"). A Claim Notice
     shall specify, to the extent known by the Indemnified Party, the nature of
     and specific basis for any Claims or the nature of and specific basis of
     any suit, action, investigation or proceeding set forth therein and the
     amount or the good faith estimated amount thereof to the extent then
     practicable. Any failure on the part of any Indemnified Party promptly to
     provide a Claim Notice to the Indemnifying Party shall relieve the
     Indemnifying Party of such party's obligation under this Article only to
     the extent that the Indemnifying Party shall have been prejudiced by the
     lack of timely and adequate notice to the Indemnifying Party.

          (b) Notice Required. The Indemnifying Party shall have thirty (30)
     days from the delivery or receipt of a Claim Notice ("Notice Period") to
     notify the Indemnified Party (i) whether or not it disputes the liability
     of the Indemnifying Party to the Indemnified Party hereunder with respect
     to the Claims identified in the Claim Notice, and (ii) whether or not it
     desires to assume the defense of the Third Party Claim identified in the
     Claim Notice; provided, however, that any Indemnified Party is hereby
     authorized during the Notice Period to file any motion, answer or other
     pleading that shall be necessary or appropriate to protect its interest or
     those of the Indemnifying Party. In the event that the Indemnifying Party
     notifies the Indemnified Party within the Notice Period that it desires to
     defend the Indemnified Party against the Claims identified in the Claims
     Notice, the Indemnifying Party shall have the right and obligation, at its
     sole cost and expense, to defend with counsel of its own choosing by all
     appropriate proceedings, which proceedings shall be properly and diligently
     settled or prosecuted to a final non-appealable order of a court of
     competent jurisdiction; provided, however, that (a) the Indemnified Party
     shall at all times have the right, at its sole option and expense, to
     employ separate counsel and to participate fully in the defense, compromise
     or settlement thereof, and (b) if the Indemnifying Party does not proceed
     diligently to defend the Claim within thirty (30) days after personal
     delivery or receipt of a Claim Notice, the Indemnified Party shall have the
     right, but not the obligation, to undertake the defense of any such Claim
     and the Indemnifying Party shall be bound by any defense or settlement that
     the Indemnified Party may make as to such Claim. Upon its assumption of the
     defense of any such Claim, the Indemnifying Party shall have full control
     of such defense and proceedings including any compromise or settlement
     thereof. If there is more than one Indemnifying Party, then all
     Indemnifying Parties must coordinate the defense of the

                                      -32-

<PAGE>

     Indemnified Party against any Claims so as not adversely to affect the
     Indemnified Party's right to a proper defense.

          (c) Cooperation. The parties agree reasonably to cooperate with one
     another and their respective counsel in contesting and defending any Claim
     by a Third Party (including granting reasonable access to the pertinent
     books, records and personnel (to the extent such personnel are available)
     in their possession or control) or, if appropriate and related to the Claim
     in question, in making (i) any counterclaim against the Third Party
     asserting the Claims, or (ii) any cross complaint against any Person.

          (d) No Settlement. Notwithstanding anything in this Section to the
     contrary, the Indemnifying Party shall not, without the written consent of
     the Indemnified Party (i) settle or compromise any Claim or consent to the
     entry of any judgment with respect to such Claim that does not include as
     an unconditional term thereof the delivery by the claimant or plaintiff to
     the Indemnified Party of a written release from all liability in respect to
     such Claim, (ii) settle or compromise any Claim in any manner that may
     materially and adversely affect the Indemnified Party, or (iii) settle or
     compromise any Claim in a manner that will require the Indemnified Party to
     pay any money.

          (e) Rights of Indemnified Party to Defend. If the Indemnifying Party
     fails to notify the Indemnified Party within the Notice Period that the
     Indemnifying Party elects to defend the Indemnified Party pursuant to
     Section 11.3(b), or if the Indemnifying Party elects to defend the
     Indemnified Party pursuant to Section 11.3(b), but fails diligently and
     promptly to prosecute, defend or settle any Claim by a Third Party, then
     the Indemnified Party shall have the right to defend, or compromise and
     settle at the sole cost and expense of the Indemnifying Party, such Claim
     by a Third Party by all appropriate proceedings, which proceedings may be
     prosecuted by the Indemnified Party to a final non-appealable order of a
     court of competent jurisdiction or settled without the consent of the
     Indemnifying Party. The Indemnified Party shall have full control of such
     defense and proceedings.

          (f) Direct Claims. In the event any Indemnified Party should have a
     Claim against any Indemnifying Party hereunder that does not involve
     damages being asserted against or sought to be collected from it by a Third
     Party, the Indemnified Party shall send a Claim Notice containing the same
     type of information required by Section 11.3(a) with respect to such Claim
     to the Indemnifying Party. If the Indemnifying Party does not notify the
     Indemnified Party within the Notice Period that it disputes such Claim, the
     amount of such damages shall be conclusively deemed a liability of the
     Indemnifying Party hereunder.

     11.4. DAMAGES. THE PARTIES AGREE THAT SUBJECT TO THE SECOND SENTENCE OF
THIS SECTION, IT IS THEIR INTENT THAT NOTWITHSTANDING ANYTHING TO THE CONTRARY
CONTAINED IN THIS AGREEMENT, NEITHER SELLER NOR BUYER SHALL BE LIABLE TO ANY
OTHER PARTY HERETO OR TO ITS AFFILIATES, OR ITS OR THEIR OFFICERS, DIRECTORS,
SHAREHOLDERS SUCCESSORS OR PERMITTED ASSIGNS, FOR CLAIMS FOR CONSEQUENTIAL,
SPECIAL, TREBLE, EXEMPLARY, INCIDENTAL, INDIRECT OR PUNITIVE DAMAGES

OF ANY NATURE UNDER OR PURSUANT TO THIS AGREEMENT OR IN CONNECTION WITH OR
RESULTING FORM THE TRANSACTIONS CONTEMPLATED HEREBY, INCLUDING CLAIMS IN THE
NATURE OF LOSS OF VALUE (INCLUDING, WITHOUT LIMITATION, ADVERSE EFFECTS ON CASH
FLOW OR EARNINGS) IRRESPECTIVE OF WHETHER SUCH CLAIMS ARE BASED UPON NEGLIGENCE,
STRICT LIABILITY, CONTRACT, OPERATION OF LAW OR OTHERWISE. NOTWITHSTANDING THE
FOREGOING, IT IS SPECIFICALLY INTENDED BY THE PARTIES THAT AN INDEMNIFIED PARTY
SHALL BE ENTITLED TO INDEMNIFICATION BY THE INDEMNIFYING PARTY PURSUANT TO THIS
ARTICLE FOR ANY AND ALL CONSEQUENTIAL, SPECIAL, TREBLE, EXEMPLARY, INCIDENTAL,
INDIRECT OR PUNITIVE DAMAGES INCLUDED IN, ARISING OUT OF OR RESULTING FROM ANY
CLAIMS ASSERTED AGAINST OR SOUGHT TO BE COLLECTED FROM ANY INDEMNIFIED PARTY BY
A THIRD PARTY.

     11.5. Survival and Time Limitation. All of the representations, warranties,
covenants, obligations and agreements of the parties set forth in this Agreement
shall survive the Closing. Except as provided in the following sentence, any
assertion by any Indemnified Party that an Indemnifying Party is liable for
indemnification under the terms of this Agreement must be made in writing and
must be given to the Indemnifying Party on or prior to the date that is
thirty-six (36) months after the Closing Date. Claims asserted by any Buyer
Indemnified Party pursuant to Section 11.2(b), 11.2(c), or 11.2(e), or Claims
asserted by any Seller Indemnified Party pursuant to Sections 11.1(b), 11.1(c)
or Section 11.1(d)may be brought at any time, irrespective of any limits
otherwise imposed by contract or under Applicable Law; Claims asserted by any
Buyer Indemnified Party pursuant to Section 11.2(d) may be brought at any time
prior to ninety (90) days after the date on which the applicable statute of
limitations expires with respect to such matter and Seller hereby agrees not to
assert as a defense any statute of limitations, statute of repose, laches or
other defense.

     11.6. Limitation on Indemnity. Notwithstanding any other provision of this
Agreement to the contrary or otherwise, Buyer acknowledges and agrees that
Seller shall not be liable to Buyer in respect of any indemnification hereunder
until and except to the extent the amount of Claims of the Buyer Indemnified
Parties under this Agreement (other than Claims (i) asserted pursuant to
Sections 2.4, 2.5, 2.6, 2.8, 7.1, 7.14 or payment obligations to Buyer under an
Alternative Arrangement, (ii) asserted pursuant to Section 12.1(a) or (iii)
arising out of Seller's fraud or willful misconduct, for which the following
deductible shall not apply), individually or in the aggregate, exceeds One
Hundred Thousand and No/100 Dollars ($100,000). Notwithstanding any other
provision of this Agreement to the contrary or otherwise, Seller acknowledges
and agrees that Buyer shall not be liable to Seller in respect of any
indemnification hereunder until and except to the extent the amount of Claims of
the Seller Indemnified Parties under this Agreement (other than Claims (i)
asserted pursuant to Sections 2.4, 2.5, 2.6, 2.8, 7.1, 7.14 or payment
obligations to Seller under an Alternative Arrangement, or (ii) arising out of
Buyer's fraud or willful misconduct, for which the following deductible shall
not apply), individually or in the aggregate, exceeds Fifty Thousand and No/100
Dollars ($50,000).

     11.7. Sole Remedy. Except for the remedies of specific performance,
injunctive relief and other equitable rights and remedies expressly permitted or
allowed pursuant to the other

                                      -34-

<PAGE>

provisions of this Agreement, the respective indemnification and rights to
recover provided in this Article XI shall be the sole and exclusive remedy for
any and all damages, liabilities, losses, loss of value, claims, deficiencies,
penalties, interest, expenses, fines assessments, charges and costs, including
without limitation attorneys fees and court cost, resulting from, arising out of
or in any way connected with or based on this Agreement or the sale of the
Specified Assets to Buyer, including any breaches of or inaccuracies in any
representation or warranty contained in this Agreement or any certificates
delivered pursuant to Article V or any breach, non-fulfillment or default in the
performance of any of the covenants or agreements contained in this Agreement;
provided, however, that this section shall not in anyway limit, impair or
otherwise affect the rights and remedies of the parties (a) for breach of the
confidentiality obligations set forth in Section 7.9 of this Agreement, (b) in
the event of a breach or default under the Noncompetition Agreement or (c) in
the event of fraud or willful misconduct.

                                   ARTICLE XII
                                   TAX MATTERS

     12.1. Liability for Taxes.

          (a) Seller's Liability. Seller shall be solely liable for (i) any
     Taxes attributable to the Specified Assets or the Business, with respect to
     any taxable periods or portions thereof ending on or before the Closing
     Date (or the portion, as determined in accordance with Section 12.1(b), of
     any such Taxes attributable to the Specified Assets or the Business for
     taxable periods beginning before and ending after the Closing Date which is
     allocable to the portions of such period occurring on or before the Closing
     Date) (the "Pre-Closing Date Period"), and (ii) any Taxes attributable to a
     breach by Seller of any representation, warranty, or covenant with respect
     to Taxes in this Agreement.

          (b) Pre-Closing Date Period Allocation. Whenever it is necessary for
     purposes of Section 12.1(a) to determine the portion of any Taxes
     attributable to the Specified Assets or the Business for a taxable period
     beginning before and ending after the Closing Date, which is allocable to
     the Pre-Closing Date Period, the determination shall be made, in the case
     of property or ad valorem taxes, on a per diem basis and, in the case of
     other Taxes, by assuming that the Pre-Closing Date Period constitutes a
     separate taxable period and by taking into account actual taxable events
     occurring during such period (except that exemptions, allowances and
     deductions for a taxable period beginning before and ending after the
     Closing Date that are calculated on an annual or periodic basis, such as
     the deduction for depreciation, shall be apportioned to the Pre-Closing
     Date Period ratably on a per diem basis).

     12.2. Audits or Assessments. Buyer shall promptly notify Seller in writing
upon receipt by Buyer of notice of any pending or threatened tax audits or
assessments that could reasonably affect the tax liabilities for which Seller
would be liable under Section 12.1(a) ("Seller Tax Matter"). Notwithstanding
anything to the contrary set forth in this Agreement, Seller shall have the sole
right to represent the interests of Seller in connection with any Seller Tax
Matter (including the right to choose Seller's representation in any audit,
contest or administrative or judicial proceeding involving a Seller Tax Matter,
the right to choose the manner in which Seller contest any assessment or
proposed disallowance or claim in any Seller Tax Matter and the right

                                      -35-

<PAGE>

to settle or otherwise compromise any Seller Tax Matter), but Buyer (a) shall
have the right to participate therein and to approve any settlement that would
affect any Tax liabilities of Buyer after the Closing Date and (b) shall have
the right to participate jointly with Seller in any Seller Tax Matters that
could give rise to any Tax liens on the assets of Buyer, or any of its
Affiliates.

                                  ARTICLE XIII
                             RESOLUTION OF DISPUTES

     13.1. Agreement to Arbitrate. Any and all claims, counterclaims, demands,
causes of action, disputes, controversies, and other matters in question arising
out of or relating to this Agreement, or the alleged breach hereof, or in any
way relating to the subject matter of this Agreement or the relationship between
the parties created by this Agreement (all of which are referred to herein as
"Disputes"), between the parties (each a "Disputing Party") shall be resolved by
final and binding arbitration, regardless of whether such Disputes (a) allegedly
are extra-contractual in nature, (b) sound in contract, tort, or otherwise, (c)
are provided for by statute or otherwise, or (d) seek damages or any other
relief, whether at law, in equity or otherwise; provided, however, that no
Dispute shall be submitted to arbitration until sixty (60) days have passed
(without mutual agreement having been reached) following receipt of the first
written notice from a Disputing Party shall, if requested by the other Disputing
Party that sets forth the subject matter of the Dispute and that states that it
is being given pursuant to this Article XIII. During such 60-day period, each
Disputing Party shall, if requested by the other Disputing Party, select and
appoint a senior management representative to seek to reach mutual agreement
with respect to the applicable Dispute. Each such appointment shall be made by
the Disputing Party's giving of notice of the appointment to the other Disputing
Party with ten (10) Business Days of receipt of the request for the appointment.
The appointees shall meet and shall negotiate in good faith and endeavor to
reach such mutual agreement as soon as practicable.

     13.2. Appointment of Arbitrator. If no such mutual agreement has been
reached within such 60-day period, then either Disputing Party may refer the
claim to arbitration under the following provisions:

          (a) To refer a Dispute to arbitration, a Disputing Party must provide
     notice to the American Arbitration Association ("AAA") and the other
     Disputing Party stating (i) a general description of the Dispute and (ii)
     that the Dispute is being referred to arbitration under this Article XIII.

          (b) The arbitration tribunal shall consist of three arbitrators. Each
     Disputing Party shall appoint one arbitrator. If, on the 30th day following
     the notice described in Section 13.2(a), a Disputing Party has failed to
     appoint its arbitrator, then the AAA shall promptly appoint an arbitrator
     on such Disputing Party's behalf. Once two arbitrators have been appointed
     by or on behalf of the Disputing Parties, such appointed arbitrators shall
     jointly select and appoint the third arbitrator. If, on the 30th day
     following the date of appointment of the second arbitrator, the two
     appointed arbitrators have failed to jointly select and appoint the third
     arbitrator, then the AAA shall promptly appoint the third arbitrator.

                                      -36-
<PAGE>

     13.3. Authority of the Arbitrators. The validity, construction, and
interpretation of the agreement to arbitrate in this Article XIII, and all
procedural aspects of the arbitration conducted pursuant to this agreement to
arbitrate, including, but not limited to, the determination of the issues that
are subject to arbitration (i.e., arbitrability), the scope of the arbitrable
issues, allegations of "fraud in the inducement" to enter into this agreement to
arbitrate, allegations of waiver, laches, delay or other defenses to
arbitrability, and the rules governing the conduct of the arbitration (including
the time for filing an answer, the time for the filing of counterclaims, the
times for amending the pleadings, the specificity of the pleadings, the extent
and scope of discovery, the issuance of subpoenas, the times for the designation
of experts, whether the arbitration is to be stayed pending resolution of
related litigation involving third parties not bound by this agreement to
arbitrate, the receipt of evidence, and the like) shall be decided by the
arbitrators. EXCEPT AS PROVIDED IN SECTION 11.4, THE ARBITRATORS SHALL HAVE
ABSOLUTELY NO AUTHORITY TO AWARD CONSEQUENTIAL, SPECIAL, TREBLE, EXEMPLARY,
INCIDENTAL, INDIRECT OR PUNITIVE DAMAGES OF ANY TYPE UNDER ANY CIRCUMSTANCES,
REGARDLESS OF WHETHER SUCH DAMAGES MAY BE AVAILABLE UNDER APPLICABLE LAW. The
arbitrators shall have the authority to assess the costs and expenses of the
arbitration proceeding (including the arbitrators' fees and expenses) against
one or both of the Disputing Parties in whatever manner or allocation the
arbitrators deem appropriate, provided that each Disputing Party shall bear its
own attorneys' fees, and the arbitrators shall have no authority to award
attorneys' fees.

     13.4. Place and Conduct of Arbitration. The arbitration proceeding shall be
conducted in Harrisburg, PA. The arbitration shall be conducted by the
arbitrators as expeditiously as possible. The arbitration shall be conducted
under the Rules of Arbitration of the AAA Commercial Arbitration Rules and
Procedures.

     13.5. Payment and Finality of Award. Each Disputing Party against which the
award or decision of the arbitrators (the "Award") assesses a monetary
obligation shall pay that obligation on or before the 30th day following the
Award or such other date as the Award may provide, which Award shall be payable
in cash in US Dollars. The Award shall, as between the Disputing Parties and
those in privity with them, be final and binding and entitled to all of the
protections and benefits of a final judgment, e.g., res judicata (claim
preclusion) and collateral estoppel (issue preclusion), as to all Disputes,
including compulsory counterclaims, that were or could have been presented to
the arbitrators. The Award shall not be reviewable by or appealable to any
court.

     13.6. Use of the Courts. It is the intent of the Parties that the
arbitration proceeding shall be conducted expeditiously, without initial
recourse to the courts and without interlocutory appeals of the arbitrators'
decisions to the courts. However, if a Disputing Party refuses to honor its
obligations under this agreement to arbitrate, the other Disputing Party may
obtain appropriate relief compelling arbitration in any court having
jurisdiction over the Disputing Parties; the order compelling arbitration shall
require that the arbitration proceedings take place in Harrisburg, Pennsylvania,
as specified above. The Disputing Parties may apply to any court having
jurisdiction for orders requiring witnesses to obey subpoenas issued by the
arbitrators. Moreover, any and all of the arbitrators' orders and decisions may
be enforced if necessary by any court having jurisdiction. The Award may be
confirmed in, and judgment upon the Award entered by, any court having
jurisdiction.

                                      -37-

<PAGE>

     13.7. Arbitration Provision Enforceable. A Disputing Party's breach of this
Agreement shall not affect the agreement to arbitrate set forth in this Article
XIII. Moreover, the Parties' obligations under this arbitration provision are
enforceable even after this Agreement has terminated. The invalidity or
unenforceability of any provision of the agreement to arbitrate set forth in
this Article XIII shall not affect the validity or enforceability of the
Disputing Parties' obligation to submit their Disputes to binding arbitration or
the other provisions of this agreement to arbitrate.

THE REINFORCED EARTH COMPANY(R) HAS PURCHASED CERTAIN ASSETS OF THE L.B. FOSTER
COMPANY

Vienna, VA, February, 2006. The Reinforced Earth Company (RECo) has acquired
certain assets from the L.B. Foster Company (NASDAQ:FSTR), a 104 year old
American corporation involved in the manufacture, fabrication and distribution
of products for the transportation, construction, utility and energy industries.
L.B. Foster anticipates realizing a net gain of under $_,,. from this
transaction. The acquisition of the proprietary, patented Mechanical Stabilized
Earth (MSE) system, marketed and sold by L.B. Foster under the trade name
Retained Earth'~, positions RECo to offer a wider range of products,
reinforcement selections, engineering services and new innovative products to
the market.

REC0, the original inventor of MSE technology, with over 34 years of experience
in the United States and activity in every State Department of Transportation,
will continue to focus attention on service, training, quality and presenting an
unparalleled range of economic and operational benefits to its customers. In
addition, this acquisition will also lead to improved synergies with its sister
companies within the USA Freyssinet Group. Working with DGI-Menard, who has
significant expertise in ground improvement technologies, and Freyssinet LLC, an
established leader in post-tensioning and stay cable structures, will allow RECo
to center more energy on offering enhanced product solutions and improved
problem solving capabilities, as the industry moves more to a design build
project approach.

                                   SUBCONTRACT

THIS SUBCONTRACT, dated this __ of February, 2006, is by and between The
Reinforced Earth Company ("RECo") and L.B. Foster Company ("Foster").

Background: Foster and RECo entered into an Asset Purchase Agreement dated as of
__________, 2006 (the "Purchase Agreement") pursuant to which RECo agreed to
acquire the Specified Assets and assume the Specified Liabilities. Capitalized
terms used in this Subcontract and not otherwise defined herein shall have the
meaning assigned to such terms in the Purchase Agreement.

Pursuant to the Purchase Agreement Foster intends to assign and REC9 intends to
take assignment of the Specified Contracts, which assignment requires the
necessary third-party consents identified in the Purchase Agreement. As of the
Closing, not all required consents have been obtained. Since substantially all
the other Specified Assets of the Business will be transferred to RECo as of the
Closing, the parties desire to into this Subcontract pursuant to which REC0
agrees to perform the obligations (and receive the benefits) of the identified
Contracts and Foster agrees to retain the direct relationship with the Customers
under such Deferred Contracts and to take actions consistent with the direct
relationship retained by Foster.

NOW THEREFORE RECo and Foster agree as follows:

     1.   With respect to the Deferred Contracts identified in Attachment "A",
          Foster and RECo enter into this subcontract, to be effective after the
          Closing, and RECo agrees to perform all the work and obligations
          required under such Deferred Contracts in accordance with their
          respective terms and conditions. Foster and REC0 agree to assist each
          other with the relationship with each customer or vendor under such
          Deferred Contracts, including without limitation, assistance with
          issuance of invoices to such Customer, assistance with collection of
          amounts due under such Deferred Contracts and prompt payment with
          respect to vendor invoices.

     2.   In return for RECo's performance of obligations under the Deferred
          Contracts, RECo shall be entitled to receive all amounts payable to
          Foster under each of the Deferred Contracts with respect to work
          performed by RECo after the Closing. Foster shall immediately (but in
          no event later than five (5) days after receipt from the Customer) pay
          to RECo any amounts it receives under the Deferred Contracts for work
          performed by RECo after the Closing. With respect to any invoices

<PAGE>

          from a vendor under a Deferred Contract, RECo shall either timely pay
          such vendor directly (with instructions to apply such payment against
          such invoice) or pay the invoiced amount to Foster at least 5 days
          prior to such invoice's due date, and Foster in turn, shall pay such
          invoice(s), with such funds received from RECo, within 5 days of its
          receipt of such funds from RECo.

     3.   The parties will continue seeking consents for the assignment of the
          Deferred Contracts in accordance with the terms of the Purchase
          Agreement.

     4.   Upon receipt of a consent for assignment of any such Deferred
          Contracts, the party receiving the consent shall provide the other
          party with a copy of such consent(s) together with a revised version
          of Attachment "A" excluding such Deferred Contract(s) for which
          consent has been obtained. Upon the receiving party's acknowledgment
          of such modified Attachment "A", it shall replace the Attachment "A"
          then in force and this' Subcontract will terminate as to such Deferred
          Contracts for which a consent has been obtained, and such Deferred
          Contracts automatically will conclusively be deemed assumed by RECo as
          a Specified Contract. Once consents are received for all Deferred
          Contracts (and they are deemed Specified Contracts), this Subcontract
          shall terminate. Termination of this Subcontract shall not affect
          either party's obligation to make payments to the other.

     5.   This Subcontract is being executed to fulfill the obligations of the
          parties pursuant to Section 2.1 and 7.9 of the Purchase Agreement and
          is not meant to add to or subtract from the rights of the respective
          parties under the Purchase Agreement. In the event of any conflict or
          inconsistency between the terms of this Subcontract and the Purchase
          Agreement, the Purchase Agreement shall prevail.
