were issued 8% convertible debentures with an original aggregate principal
amount of $7,000,000 and warrants to purchase shares of Common Stock; and

     WHEREAS, the parties wish to amend certain terms of the Transaction

     2.   Amendments to Section 1 of the Debenture.

          a)   The definition of "Quarterly Redemption Amount" set forth in
     Section 1 of the Debentures is hereby amended such that the Quarterly
     Redemption Amount for each Quarterly Redemption as to a Purchaser shall
     equal the amounts set forth on Schedule 1 attached hereto.

          b)   The definition of "Quarterly Redemption Date" set forth in
     Section 1 of the Debentures is hereby amended and restated as follows:

          "Quarterly Redemption Date" means each January 1, April 1, July 1 and
          October 1, commencing on April 1, 2008 and ending upon the full
          redemption of this Debenture.

     3.   Effect on Purchase Agreement. The foregoing amendments are given
solely in respect of the transactions described herein. Except as expressly set
forth herein, all of the terms and conditions of the Transaction Documents, as
amended, shall continue in full force and effect after the execution of this
Agreement, and shall not be in any way changed, modified or superseded by the
terms set forth herein. This Agreement shall not constitute a novation or
satisfaction and accord of any Transaction Document.

     4.   Filing of Form 8-K. Within 2 Trading Days of the effective date of
this Agreement, the Company shall issue a Current Report on Form 8-K, reasonably
acceptable to each Purchaser disclosing the material terms of the transactions
contemplated hereby, which

                                        1
<PAGE>
shall include this Agreement as an attachment thereto. In addition, within 2
Trading Days of the date hereof, the Company shall file prospectus supplements
under Rule 424 under the Securities Act to registration statement number
333-130900 and registration statement number 333-138977 (collectively, the

     5.   Conditions to Purchasers Obligations. The respective obligations of
the Purchasers hereunder in connection with the Closing are subject to the
following conditions being met:

          a)   the accuracy in all material respects on the date of the Closing
     of the representations and warranties of the Company contained herein;

          b) all obligations, covenants and agreements of the Company required
     to be performed at or prior to the Closing shall have been performed;

          c) all Purchasers parties to the Purchase Agreement shall have agreed
     to the terms and conditions of this Agreement;

          d) there shall have been no Material Adverse Effect with respect to
     the Company since the date hereof; and

          e) from the date hereof to the Closing, trading in the Common Stock
     shall not have been suspended by the Commission (except for any suspension

     declared either by the United States or New York State authorities nor
     shall there have occurred any material outbreak or escalation of
     hostilities or other national or international calamity of such magnitude
     in its effect on, or any material adverse change in, any financial market
     which, in each case, in the reasonable judgment of each Purchaser, makes it
     impracticable or inadvisable to consummate the transactions hereunder.

     6.   Representations and Warranties of the Company. The Company hereby
makes the representations and warranties set forth below to the Purchasers that
as of the date of its execution of this Agreement:

          a)   Authorization; Enforcement. The Company has the requisite
     corporate power and authority to enter into and to consummate the
     transactions contemplated by this Agreement and otherwise to carry out its
     obligations hereunder and thereunder. The execution and delivery of this
     Agreement by the Company and the consummation by it of the transactions
     contemplated hereby have been duly authorized by all necessary action on
     the part of such Company and no further action is required by such Company,
     its board of directors or its stockholders in connection therewith. This
     Agreement has been duly executed by the Company and, when delivered in
     accordance with the terms hereof

                                        2
<PAGE>
     will constitute the valid and binding obligation of the Company enforceable
     against the Company in accordance with its terms except (i) as limited by
     general equitable principles and applicable bankruptcy, insolvency,
     reorganization, moratorium and other laws of general application affecting
     enforcement of creditors' rights generally, (ii) as limited by laws
     relating to the availability of specific performance, injunctive relief or
     other equitable remedies and (iii) insofar as indemnification and
     contribution provisions may be limited by applicable law.

          b)   No Conflicts. The execution, delivery and performance of this
     Agreement by the Company and the consummation by the Company of the
     transactions contemplated hereby do not and will not: (i) conflict with or
     violate any provision of the Company's certificate or articles of
     incorporation, bylaws or other organizational or charter documents, or (ii)
     conflict with, or constitute a default (or an event that with notice or
     lapse of time or both would become a default) under, result in the creation
     of any lien upon any of the properties or assets of the Company, or give to
     others any rights of termination, amendment, acceleration or cancellation
     (with or without notice, lapse of time or both) of, any material agreement,
     credit facility, debt or other material instrument (evidencing Company debt
     or otherwise) or other material understanding to which the Company is a
     party or by which any property or asset of the Company is bound or
     affected, or (iii) conflict with or result in a violation of any law, rule,
     regulation, order, judgment, injunction, decree or other restriction of any
     court or governmental authority to which the Company is subject (including
     federal and state securities laws and regulations), or by which any
     property or asset of the Company is bound or affected.

          c)   Capitalization. The Company is a duly organized and validly
     existing corporation in good standing under the laws of the State of
     Nevada. The capitalization of the Company is as set forth on Schedule 6(c).
     There are 56,756,098 shares of Common Stock issued and outstanding, all of
     which are validly issued, fully paid and nonassessable. Except (i) as set
     forth on the Disclosure Schedules to the Purchase Agreement, (ii) as set
     forth in the sections of the Registration Statements captioned "Security
     Ownership of Certain Beneficial Owners and Management" and (iii) for
     options granted to the Company's employees pursuant to its broad based
     stock option plan, there are no issued or outstanding securities and no
     issued or outstanding options, warrants or other rights, or commitments or
     agreements of any kind, contingent or otherwise, to purchase or otherwise
     acquire shares of Common Stock or any issued or outstanding securities of
     any nature convertible into shares of Common Stock. There is no proxy or
     any other agreement, arrangement or understanding of any kind authorized,
     effective or outstanding which restricts, limits or otherwise affects the
     right to vote any shares of Common Stock.

     7.   Representation and Warranty of the Purchasers. The Purchasers
severally and not jointly hereby make the representation and warranty set forth
below to the Company that as of the date of its execution of this Agreement,
such Purchaser represents and warrants that (a) the execution and delivery of
this Agreement by it and the consummation by it of the transactions contemplated
hereby have been duly authorized by all necessary action on its behalf and (b)
this Agreement has been duly executed and delivered by such Purchaser and
constitutes the valid and

                                        3
<PAGE>
binding obligation of such Purchaser, enforceable against it in accordance with
its terms except (i) as limited by general equitable principles and applicable
bankruptcy, insolvency, reorganization, moratorium and other laws of general
application affecting enforcement of creditors' rights generally, (ii) as
limited by laws relating to the availability of specific performance, injunctive
relief or other equitable remedies and (iii) insofar as indemnification and
contribution provisions may be limited by applicable law.

     8.   Notices. Any and all notices or other communications or deliveries
required or permitted to be provided hereunder shall be made in
accordance with the provisions of the Purchase Agreement.

     9.   Survival. All warranties and representations (as of the date such
warranties and representations were made) made herein or in any certificate or
other instrument delivered by it or on its behalf under this Agreement shall be
considered to have been relied upon by the parties hereto. This Agreement shall
inure to the benefit of and be binding upon the successors and permitted assigns
of each of the parties; provided however that no party may assign this Agreement
or the obligations and rights of such party hereunder without the prior written
consent of the other parties hereto.

     10.  Execution. This Agreement may be executed in two or more counterparts,
all of which when taken together shall be considered one and the same agreement
and shall become effective when counterparts have been signed by each party and
delivered to the other party, it being understood that both parties need not
sign the same counterpart. In the event that any signature is delivered by
facsimile transmission, such signature shall create a valid and binding
obligation of the party executing (or on whose behalf such signature is
executed) with the same force and effect as if such facsimile signature page
were an original thereof.

     11.  Severability. If any provision of this Agreement is held to be invalid
or unenforceable in any respect, the validity and enforceability of the
remaining terms and provisions of this Agreement shall not in any way be
affected or impaired thereby and the parties will attempt to agree upon a valid
and enforceable provision that is a reasonable substitute therefor, and upon so
agreeing, shall incorporate such substitute provision in this Agreement.

     12.  Governing Law. All questions concerning the construction, validity,
enforcement and interpretation of this Agreement shall be determined pursuant to
the Governing Law provision of the Purchase Agreement.

     13.  Entire Agreement. The Agreement, together with the exhibits and
schedules thereto, contain the entire understanding of the parties with respect
to the subject matter hereof and supersede all prior agreements and
understandings, oral or written, with respect to such matters, which the parties
acknowledge have been merged into such documents, exhibits and schedules.

     14.  Construction. The headings herein are for convenience only, do not
constitute a part of this Agreement and shall not be deemed to limit or affect
any of the provisions hereof.

                                        4
<PAGE>
The language used in this Agreement will be deemed to be the language chosen by
the parties to express their mutual intent, and no rules of strict construction
will be applied against any party.

     15.  Independent Nature of Purchasers' Obligations and Rights. The
obligations of each Purchaser hereunder are several and not joint with the
obligations of any other Purchasers hereunder, and no Purchaser shall be
responsible in any way for the performance of the obligations of any other
Purchaser hereunder. Nothing contained herein or in any other agreement or
document delivered at any closing, and no action taken by any Purchaser pursuant
hereto, shall be deemed to constitute the Purchasers as a partnership, an
association, a joint venture or any other kind of entity, or create a
presumption that the Purchasers are in any way acting in concert with respect to
such obligations or the transactions contemplated by this Agreement. Each
Purchaser shall be entitled to protect and enforce its rights, including without
limitation the rights arising out of this Agreement, and it shall not be
necessary for any other Purchaser to be joined as an additional party in any
proceeding for such purpose.

     16.  Termination. This Agreement may be terminated by any Purchaser, as to
such Purchaser's obligations hereunder, by written notice to the
other parties, if the Closing has not been consummated on or before December 31,
2007.

     17.  Fees and Expenses. Each party shall pay the fees and expenses of its
advisers, counsel, accountants and other experts, if any, and
all other expenses incurred by such party incident to the negotiation,
preparation, execution, delivery and performance of this Agreement.

Agreement; (b) conflict with or result in a breach of or default under any of the terms, conditions

Obligation, including the Assumed Contracts, to which Seller is a party or otherwise subject, or by
which Seller or any of Seller’s material assets or properties, including the Assets, may be bound
or subject, in each case where such conflict, breach or default may reasonably be expected to

contemplated hereby or thereby or restrict Buyer’s ability to use the Assets after the Closing or
adversely affect the validity and enforceability of this Agreement; (c) result in the creation or
imposition of any Lien upon Seller’s material assets or properties, including the Assets, other

any material Contractual Obligation, including the Assumed Contracts, to which Seller is a party or
otherwise subject, or by which Seller or any of Seller’s material assets or properties, including
the Assets, may be bound or subject, in each case where such termination, cancellation,
acceleration or modification of any such Contractual Obligation may reasonably be expected to
materially and adversely affect the ability of Seller to consummate timely the transactions
contemplated hereby or thereby or restrict Buyer’s ability to use the Assets after the Closing or
adversely affect the validity and enforceability of this Agreement. Seller is not a party to, or
bound by, any agreement that is currently in effect, granting rights to any person which are
inconsistent with the rights to be granted by Seller in this Agreement and the agreements
contemplated hereby. For purposes of this Agreement, the term “Governmental Body” means any

deed of trust or other instrument to which a person is a party or by which it or any of its
properties or assets are bound. “Required Consents” means the notices, consents and approvals
required to be made or obtained under the Assumed

7

 

Contracts, the Credit Agreement, dated as of
February 27, 2007 (the “JP Morgan Credit Agreement”), among Seller, as Borrower, the lenders party
thereto and JPMorgan Chase Bank, N.A., as Administrative Agent, as amended, and the Credit
Agreement, dated as of June 19, 2007 (the “Fortis Credit Agreement” and, together with the JP
Morgan Credit Agreement, the “Credit Agreements”), among Seller, as Borrower, the Collateral Agent
as named therein, the several lenders from time to time parties thereto, and Fortis Capital Corp.,
as Administrative Agent.

     2.4 Consents and Approvals. The execution and delivery by Seller of this Agreement and the
documents contemplated hereby to be executed by Seller, compliance by Seller with the terms hereof
and thereof and consummation by Seller of the transactions contemplated hereby and thereby do not
require Seller to obtain any consent, approval or action of, make any filings with or give any
notice to any corporation, person, firm or other entity, or any Governmental Body, the failure to
obtain which or give may reasonably be expected to materially and adversely affect the ability of
Seller to timely consummate the transactions contemplated hereby or restrict Buyer’s ability to use
the Assets after the Closing or adversely affect the validity and enforceability of this Agreement,
except in each case for the Required Consents.

     2.5 Title to Properties. Seller has good, valid and indefeasible right, title and interest in
and to the Assumed Contracts, free and clear of any Liens other than (i) Permitted Liens and
(ii) Liens arising pursuant to the Credit Agreements. At the Closing, upon the sale, assignment,
transfer and conveyance of the Assumed Contracts to Buyer, there will be vested in Buyer, good,
valid and indefeasible right, title and interest in and to the Assumed Contracts, free and clear of
any Liens other than Permitted Liens. At the Closing, upon the sale, assignment, transfer and
conveyance of Seller’s right, title and interest in and to the Assets to Buyer, Buyer shall succeed
to all of Seller’s right, title and interest in and to the Assets free and clear of any Liens other
than Permitted Liens. There are no actual, pending or, to the knowledge of Seller, overtly
threatened claims against Seller’s material assets or properties, including the Assets, that could
give rise to a Lien on the Assets (other than (i) Permitted Liens and (ii) Liens arising pursuant
to the Credit Agreements), or acts or incidents which could give rise to any such claims, relating
to or arising out of Seller’s material assets or properties, including the Assets, or the operation
of Seller’s business. Except for the Assets, including the Assumed Contracts, no other assets
(tangible or intangible) owned by Seller or its Affiliates are required for the construction and
completion of the Vessel and the Cranes consistent with the Project. The Assumed Contracts
constitute all the contracts entered into by Seller to construct and complete the Vessel and the
Cranes consistent with the Project. “Project” shall mean for purposes hereof, the construction of
the Vessel as contemplated under the Construction Contract, including the most current versions of
all change orders, drawings and specifications as of the date hereof for the Vessel prepared in
connection therewith, as outfitted by the Cranes according to the specifications and drawings
therefor set forth in the other Assumed Contracts, except that the Project does not include
saturation diving systems and remotely-operated vehicles and equipment necessary for the
operation thereof.

     2.6 Solvency. Seller is not now insolvent, and will not be rendered insolvent by any of the
transactions contemplated herein. In addition, immediately after giving effect to the consummation
of the transactions contemplated herein, (a) Seller will be able to pay it debts as they become
due, (b) Seller will not have unreasonably small assets with which to conduct its present or
proposed business and (c) taking into account all pending and threatened litigation,

8

 

final judgments against Seller in actions for money damages are not reasonably anticipated to be rendered
at a time when, or in amounts such that, Seller will be unable to satisfy any such judgments
promptly in accordance with their terms (taking into account the maximum probable amount of such
judgments in any such actions and the earliest reasonable time at which such judgments might be
rendered) as well as all other obligations of Seller. The cash available to Seller, after taking
into account all other anticipated uses of the cash, will be sufficient to pay all such debts and
judgments promptly in accordance with their terms.

     2.7 Absence of Certain Changes or Events. Except for the Payment Defaults and except as
provided or contemplated by this Agreement, there has not been, occurred or arisen any of the
following as they relate to Seller, Seller’s business or Seller’s material assets or properties,
including the Assets, since September 30, 2007:

     (a) any change in, or any event, condition or state of facts of any character that has had or
would be reasonably expected to have an adverse effect on the Assets, or that adversely affects the
validity or enforceability of this Agreement;

     (b) any destruction, damage, or loss suffered with respect to any of the Assets (whether or
not covered by insurance);

     (c) any sale, charter, lease or other disposition of any of the Assets;

     (d) any mortgage, pledge, or other encumbrance of any of the Assets (other than Permitted
Liens and Liens arising under the Credit Agreements);

     (e) any entry into or amendment or termination of any Contractual Obligation to which Seller
is a party and to which any of the Assets are subject or bound that could reasonably be expected to
have an adverse effect on the Assets;

     (f) any breach of the terms of any Contractual Obligation that could reasonably be expected to

notice (the “Final Reimbursement Request”) setting forth in reasonable detail the Total Project
Costs and, if applicable, a request for payment of the Reimbursement Amount under this

previously been submitted in a Reimbursement Request by Buyer and paid by Seller.

     (g) Upon receipt of a Reimbursement Request, Seller and its representatives shall be permitted
during the succeeding 30 day period (a “Review Period”) full access at all reasonable times to the

to such historical financial information relating to the construction of the Vessels and Cranes as
Seller may reasonably request for the purpose of reviewing and verifying such Reimbursement
Request.

     (h) On or prior to the last day of the applicable Review Period, Seller may object to the
Reimbursement Request or any portion thereof by delivering to Buyer a written statement setting
forth the basis for Seller’s objections thereto (the “Statement of Objections”). If Seller fails
to deliver a Statement of Objections within the applicable Review Period, the applicable
Reimbursement Request and the applicable Total Project Costs set forth therein shall be deemed to
have been accepted by Seller and shall be used in determining the Reimbursement Amount. If Seller
delivers a Statement of Objections within the applicable Review Period, Seller and Buyer shall
negotiate in good faith to resolve such objections, and, if the same are so resolved, the
applicable Reimbursement Request and the applicable Total Project Costs, with such changes that may
have been agreed in writing by Seller
and Buyer, shall be final and binding on the parties, and shall be used in determining the
applicable Reimbursement Amount.

     (i) If Seller and Buyer shall fail to reach an agreement with respect to any of the matters
set forth in the Statement of Objections, then such unresolved matters shall, not later than 15
days after one of the parties affirmatively terminates discussions in writing with respect to the
Statement of Objections, be submitted for resolution to an independent nationally recognized
accounting firm or other qualified person (the “Accounting Expert”) reasonably satisfactory to each
of the parties. The Accounting Expert shall, acting as an expert and not as arbitrator, resolve
the disputes set forth in the Statement of Objections and make any corresponding adjustments to the
applicable Total Project Costs.

     (j) Subject to, and to the extent permitted by, any applicable Laws, Seller and Buyer shall
each make readily available to the Accounting Expert all relevant work papers and books and records
relating to the construction of the Vessel and the Cranes, and copies of all such

19

 

materials and
information provided by a party to the Accounting Expert shall be concurrently delivered to the
other parties to the proceeding.

     (k) The parties shall jointly instruct the Accounting Expert to make a determination as soon
as practicable within 30 days (or such other time as the parties hereto shall agree in writing)
after its engagement. Each party shall have the right to make a presentation of its positions in
person to the Accounting Expert. The Accounting Expert may make such inquiries of the parties as
it may deem appropriate. The Accounting Expert’s resolution of the disputes set forth in the
applicable Statement of Objections and the applicable Total Project Costs, with any such
adjustments made by the Accounting Expert, shall be final and binding upon the parties, and shall
be used in determining the applicable Reimbursement Amount.

     (l) The fees of the Accounting Expert shall be paid by the party against whom the Accounting
Expert shall rule, or if some issues are ruled against each of the parties, as otherwise equitably
divided between the parties as such Accounting Expert may deem appropriate.

applicable to an objection resolved in Buyer’s favor). Any such payment shall be in United States

claims asserted by Buyer pursuant to Section 4.11 or Article 8 of this Agreement, Buyer may at its
sole option agree to an earlier cancellation of the Letter of Credit if Seller provides substitute

ARTICLE 8

INDEMNIFICATION

     8.1 In General.

     (a) Except for any cause of action for fraud and any claims for specific performance of any
covenants set forth in this Agreement, from and after the Closing, the indemnification provided in
this  Article 8 shall be the sole and exclusive remedy of any party arising out of, related to, in
connection with or with respect to this Agreement; provided, however, that this clause shall not

Buyer’s Affiliates pursuant to the terms of this Agreement or the transactions contemplated hereby

     (c) Effective as of the Closing Date, Buyer hereby irrevocably and unconditionally waives, and

or appropriate to give full effect to this Section  8.1(c).

     8.2 Indemnification of Buyer Indemnitees. Subject to the limitations set forth in  Article 7
and this  Article 8, Seller hereby agrees to indemnify and hold the Buyer Indemnitees harmless from
and against all Adverse Consequences arising out of, based upon or resulting from:

     (a) any breach of representation or warranty of Seller contained in  Article 2 of this
Agreement or in any Officer’s Certificate delivered pursuant to  Article 5;

26

 

     (b) any breach or non-fulfillment of any covenant or agreement on the part of Seller under the
terms of this Agreement;

     (c) any Taxes payable by Seller arising from, based upon or relating to the sale of the Assets
pursuant to this Agreement (except as provided in Sections  1.6 and  1.7);

     (d) the Excluded Liabilities and the Excluded Assets;

     (e) any breach or default by Seller under the Assumed Contracts prior to the Closing Date
(other than with respect to the Payment Defaults); and

     (f) the ownership of the Seller’s business and/or the use and operation of the Seller’s
business on or before the Closing Date (other than with respect to the Payment Defaults).

     8.3 Indemnification of Seller Indemnitees. Subject to the limitations set forth in  Article 7
and this  Article 8, Buyer agrees to indemnify and hold the Seller Indemnitees harmless from and

Closing Date.

     8.4 Limitation on Indemnification. Seller’s maximum aggregate liability under Section  8.2(a)
shall be limited to an amount equal to thirty-five (35%) of the Purchase Price. Notwithstanding
the foregoing, the limitations on indemnification set forth in this Section  8.4
shall not apply to any indemnification claim relating to any breach of any representation or
warranty contained in Sections  2.1,  2.2,  2.5 or  2.15.

     8.5 Method of Asserting Claims, Etc. The items listed in Section  8.2 and Section  8.3 are
sometimes collectively referred to herein as “Damages”; provided that such reference shall be
understood to mean the respective damages from and against which Buyer and its Affiliates and their
respective subsidiaries, officers, directors, managers, members, employees, representatives, agents
and attorneys (the “Buyer Indemnitees”) or Seller and its Affiliates and their respective
subsidiaries, officers, directors, employees, representatives, agents and attorneys (the “Seller
Indemnitees”), as the case may be, are indemnified as the context requires. The person claiming
indemnification hereunder, whether a Buyer Indemnitee or a Seller Indemnitee, is sometimes referred
to as the “Indemnified Party” and the party against whom such claims are asserted hereunder is
sometimes referred to as the “Indemnifying Party.” All claims for

27

 

indemnification by an
Indemnified Party under Section 8.2 or Section 8.3 hereof, as the case may be, shall be asserted
and resolved as follows:

     (a) If any claim or demand for which an Indemnifying Party would be liable for Damages to an
Indemnified Party hereunder is overtly asserted against or sought to be collected from such
Indemnified Party by a third party (a “Third Party Claim”), such Indemnified Party shall with
reasonable promptness (but in no event later than thirty (30) days after the Third Party Claim is
so asserted or sought against the Indemnified Party) notify in writing the Indemnifying Party of
such Third Party Claim enclosing a copy of all papers served, if any, and specifying the nature of
and specific basis for such Third Party Claim and the amount or the estimated amount thereof to the
extent then reasonably determinable, which estimate shall not be conclusive of the final amount of
such Third Party Claim (the “Claim Notice”). For this purpose the commencement of any audit or
other investigation respecting Taxes shall constitute a Third Party Claim. Notwithstanding the
foregoing, failure to so provide a Claim Notice as provided above shall not relieve the
Indemnifying Party from its obligation to indemnify the Indemnified Party with respect to any such
Third Party Claim except to the extent that a failure to so notify the Indemnifying Party in
reasonably sufficient time prejudices the Indemnifying Party’s ability to defend against the Third
Party Claim. The Indemnifying Party shall have thirty (30) days from delivery of the Claim Notice
(the “Notice Period”) to notify the Indemnified Party (i) whether or not the Indemnifying Party
disputes the liability of the Indemnifying Party to the Indemnified Party hereunder with respect to
such Third Party Claim and (ii) whether or not the Indemnifying Party desires, at the sole cost and
expense of the Indemnifying Party, to defend the Indemnified Party against such Third Party Claim.

     (b) If the Indemnifying Party notifies the Indemnified Party within the Notice Period that the
Indemnifying Party does not dispute its liability to the Indemnified Party and that the
Indemnifying Party desires to defend the Indemnified Party with respect to the Third Party Claim
pursuant to this Article 8, then the Indemnifying Party shall have the right to defend, at its
sole cost and expense, such Third Party Claim by all appropriate proceedings, which proceedings
shall be diligently prosecuted by the Indemnifying Party to a final conclusion or settled at the
discretion of the Indemnifying Party (but only if the Indemnifying Party is liable hereunder to the
Indemnified Party for the full amount of, and all obligations under, such settlement;
otherwise, no such settlement shall be agreed to without the prior written consent of the
Indemnified Party). If the Indemnifying Party is liable hereunder to the Indemnified Party for the
full amount of such Third Party Claim, the Indemnifying Party shall have full control of such
defense and proceedings, including any compromise or settlement thereof; provided, however, that
the Indemnified Party is hereby authorized, at the sole cost and expense of the Indemnifying Party
(but only if the Indemnified Party is actually entitled to indemnification hereunder or if the
Indemnifying Party assumes the defense with respect to the Third Party Claim as permitted
hereunder), to file during the Notice Period any motion, answer or other pleadings which the
Indemnified Party shall deem necessary or appropriate to protect its interests or those of the
Indemnifying Party and not prejudicial to the Indemnifying Party (it being understood and agreed
that if an Indemnified Party takes any such action which is prejudicial and conclusively causes a
final adjudication which is adverse to the Indemnifying Party, the Indemnifying Party shall be
relieved of its obligations hereunder with respect to such Third Party Claim); and provided,
further, that if requested by the Indemnifying Party, the Indemnified Party agrees, at the sole
cost and expense of the Indemnifying Party, to cooperate with the Indemnifying Party

28

 

and its
counsel in contesting any Third Party Claim which the Indemnifying Party elects to contest, or, if
appropriate and related to the Third Party Claim in question, in making any counterclaim against
the person asserting the Third Party Claim, or any cross-complaint against any person. The
Indemnified Party may participate in, but not control (except if the Indemnifying Party is not
liable hereunder to the Indemnified Party for the full amount of such Third Party Claim, in which
case whichever of the Indemnifying Party or the Indemnified Party is liable for the largest amount
of Damages with respect to the Third Party Claim shall control), any defense or settlement of any
Third Party Claim with respect to which the Indemnifying Party is participating pursuant to this
Section 8.5(b), and except as provided in the preceding sentence, the Indemnified Party shall bear
its own costs and expenses with respect to such participation.

     (c) If the Indemnifying Party fails to notify the Indemnified Party within the Notice Period
that the Indemnifying Party does not dispute its liability to the Indemnified Party and that the
Indemnifying Party desires to defend the Indemnified Party pursuant to this Article 8, then the
Indemnified Party shall have the right to defend, at the sole cost and expense of the Indemnifying
Party, the Third Party Claim by all appropriate proceedings, which proceedings shall be promptly
and vigorously prosecuted by the Indemnified Party to a final conclusion or settled. The
Indemnified Party shall have full control of such defense and proceedings, including any compromise
or settlement thereof; provided, however, that if requested by the Indemnified Party, the
Indemnifying Party agrees, at the sole cost and expense of the Indemnifying Party, to cooperate
with the Indemnified Party and its counsel in contesting any Third Party Claim which the
Indemnified Party is contesting, or, if appropriate and related to the Third Party Claim in
question, in making any counterclaim against the person asserting the Third Party Claim, or any
cross-complaint against any person. Notwithstanding the foregoing provisions of this Section
8.5(c), if the Indemnifying Party has timely notified the Indemnified Party that the Indemnifying
Party disputes its liability to the Indemnified Party and if such dispute is resolved in favor of
the Indemnifying Party by final, non-appealable order of a court of competent jurisdiction, the
Indemnifying Party shall not be required to bear the costs and expenses of the Indemnified Party’s
defense pursuant to this Section 8.5(c) or of the Indemnifying Party’s participation therein at
the Indemnified Party’s request and the Indemnified Party shall reimburse the Indemnifying Party in
full for all costs and expenses of such litigation. The Indemnifying Party may
participate in, but not control, any defense or settlement controlled by the Indemnified Party
pursuant to this Section 8.5(c) (other than a dispute as to the Indemnifying Party’s liability to
the Indemnified Party) and the Indemnifying Party shall bear its own costs and expenses with
respect to such participation.

     (d) If any Indemnified Party should have a claim against any Indemnifying Party hereunder
which does not involve a Third Party Claim, the Indemnified Party shall notify the Indemnifying
Party of such claim by the Indemnified Party, specifying the nature of and specific basis for such
claim and the amount of the estimated amount of such claim (the “Indemnity Notice”). If the
Indemnifying Party does not notify the Indemnified Party within thirty (30) days from delivery of
the Indemnity Notice that the Indemnifying Party disputes such claim, the amount or estimated
amount of such claim as specified by the Indemnified Party shall be conclusively deemed a liability
of the Indemnifying Party. If the Indemnifying Party has timely disputed such claim, as provided
above, such dispute shall be resolved by litigation in an appropriate court of competent
jurisdiction or as the parties otherwise at such time agree.

29

 

     8.6 Payment of Indemnity. Any indemnity claim shall be paid in cash by the Indemnifying Party
to or on behalf of the appropriate Indemnified Party. At Buyer’s option, any indemnity claim can
be paid in whole or in part by Buyer drawing down under the Letter of Credit delivered by Seller to
Buyer pursuant to the terms of this Agreement.

     8.7 Indemnification Reductions and Other Matters.

     (a) Any indemnification owing to an Indemnified Party pursuant to this Article 8 shall be
reduced by any amounts actually received by the Indemnified Party in connection with (i) any
insurance coverage with respect thereto (provided that amounts covered that are subject to
retrospective payments or premiums shall be reduced (but not below zero) by the amount of such
payments or premiums) or indemnification rights (other than under this Agreement) (net of expenses
to enforce, collect and pursue a claim for such insurance coverage or indemnification), (ii) any
claims the Indemnified Party has against any third party that reduces the Adverse Consequences that
would otherwise be sustained (net of expenses to enforce, collect and pursue such claims against
third parties) or (iii) any actual reduction in cash Taxes attributable to such indemnified
liability (any such amounts received that reduce the indemnification owing to an Indemnified Party,
the “Indemnity Reduction Amounts”). If the Indemnified Party receives any Indemnity Reduction
Amounts under applicable insurance policies, or from any third party, in respect of an indemnified
Adverse Consequence after the full amount of such indemnified Adverse Consequences has been paid by
the Indemnifying Party or after an Indemnifying Party has made a partial payment of such
indemnified Adverse Consequences and such Indemnity Reduction Amounts exceed the remaining unpaid
balance of such indemnified Adverse Consequences, then such Indemnified Party shall promptly remit
to the Indemnifying Party an amount equal to the excess (if any) of (A) the amount theretofore paid
by the Indemnifying Party in respect of such indemnified Adverse Consequences, less (B) the amount
of the indemnity payment that would have been due if such Indemnity Reduction Amounts in respect
thereof had been received before the indemnity payment was made.

     (b) In the event that an Indemnifying Party makes any payment to any Indemnified Party for
indemnification for which such Indemnified Party could have collected on a claim against a third
party, the Indemnifying Party shall be entitled to pursue claims and conduct litigation in good
faith on behalf of such Indemnified Party and any of its successors, to pursue and collect in good
faith on any indemnification or other remedy available to such Indemnified Party thereunder with
respect to such claim and generally to be subrogated to the rights of such Indemnified Party, but
only to the extent the Indemnified Party has been made whole for any Damages it has suffered or
incurred, and provided that the Indemnifying Party shall fully indemnify, defend and hold the
Indemnified Party harmless from and against any claims asserted or threatened against the
Indemnified Party by any third parties in connection with the Indemnifying Party’s pursuit of such
claims. Except pursuant to a settlement agreed to by the Indemnifying Party, the Indemnified Party
shall not waive or release any material contractual right to recover from a third party any known
Adverse Consequences subject to indemnification hereby without the prior written consent of the
Indemnifying Party, which shall not be unreasonably withheld, delayed or conditioned. The
Indemnified Party shall cooperate with the Indemnifying Party, at the Indemnifying Party’s expense,
with respect to any such effort to pursue and collect with respect thereto and shall execute and
deliver to the Indemnifying Party

30

 

such documents and instruments as may be reasonably necessary or
appropriate to give full effect to this Section 8.7(b).

     (c) Any Adverse Consequences included in the calculation of Remaining Contract Payments
pursuant to Section 4.11 shall not be subject to indemnification under Section 8.2.

     8.8 Adverse Consequences. As used in this Agreement, the term “Adverse Consequences” shall
mean actions, claims, suits, debts, liabilities, obligations, losses, costs, deficiencies,
penalties, fines, expenses and other judgments (at equity or in law) and damages whenever arising
or incurred, including without limitation, amounts paid in settlement and reasonable attorneys fees
and expenses.

ARTICLE 9

TERMINATION

     9.1 Termination. This Agreement may be terminated at any time before the Closing Date:

     (a) by mutual consent of Buyer, on the one hand, and Seller, on the other hand;

     (b) by Buyer, upon notice of termination of its obligation to consummate the transaction
delivered to Seller, if Buyer reasonably has determined that there has been any material breach of
any covenant of Seller or that Seller has materially breached any of its representations or
warranties (in any case without regard to any materiality or other limitation stated in such
covenant, representation or warranty), stating in particularity the default or defaults on which
the notice is based; provided, however, that Seller shall, after receipt of such notice, have
fifteen (15) days in which to cure such material breach and, if so cured, Buyer shall, for that
reason, have no right to terminate this Agreement;

     (c)
by Seller upon notice of termination of its obligation to consummate the transaction delivered to Buyer, if Seller reasonably has determined that there has been any material breach of any covenant of Buyer or that Buyer has breached any of its representations or warranties (in any case without regard to any materiality or other limitation stated in such covenant, representation or warranty), stating in particularity
the default or defaults on which the notice is based; provided, however, that Buyer shall, after receipt of such notice, have fifteen (15) days in which to cure such material breach and, if so cured, Seller shall, for that reason, have no right to terminate this Agreement;

     (d)
by either Buyer, on the one hand, or Seller, on the other hand, if the Closing has not occurred on or before January 21, 2008; provided, however, that neither Buyer on the one hand nor Seller on the other hand shall be entitled to terminate this Agreement pursuant hereto if such party is in material breach of any of its representations, warranties or covenants contained in this Agreement;

     (e)
by either Buyer, on the one hand, or Seller, on the other hand, in accordance with Section 11.9 of this Agreement; or

31

 

     (f) by Buyer on or before January 9, 2008, if, after entering into this Agreement, any fact,
circumstance or event comes to the Buyer’s attention that, in the Buyer’s good faith, reasonable
judgment, is so materially adverse as to make it impracticable or inadvisable to proceed with the
purchase of the Assets on the terms and in the manner contemplated in this Agreement.

     9.2 Termination Remedies. Except as otherwise set forth below in this Section, if this
Agreement is terminated pursuant to Sections 9.1(a), 9.1(d), 9.1(e) or 9.1(f) above, such
termination shall be without liability to any party hereto, except as specifically provided in
Section 11.11. If this Agreement is terminated pursuant to Sections 9.1(b) or 9.1(c) above, the
rights and remedies granted hereby shall be cumulative and nonexclusive of any other right or
remedy available to the terminating party at law or in equity. The parties agree that the Assets
are unique in character and, if Seller refuses to consummate the transactions contemplated herein
for any reason other than (i) pursuant to Sections 9.1(a), 9.1(c), 9.1(d) or 9.1(e) or (ii) because
there has been a failure to satisfy any of the conditions (not otherwise waived by Seller) set
forth in Article 6, damages suffered by Buyer may not be readily ascertainable. Accordingly,
Seller agrees that Buyer, at its option, shall be entitled to seek the equitable remedy of specific
performance. The terms of Sections 1.8, 4.7, 9.2, 11.1, 11.2, 11.3, 11.4, 11.8, 11.11, 11.13,
11.14 and Article 10 shall survive the termination of this Agreement.

     11.11 Expenses. The Seller shall pay all expenses incurred by Seller in connection with the
Letter, this Agreement and the transactions contemplated hereby, including, the expenses of legal
counsel and other professional expenses, as well as other expenses incurred by the Seller in

Buyer at Closing for all actual out-of-pocket expenses reasonably incurred by Buyer in connection
with the Letter, this Agreement and the transactions contemplated hereby, including, all legal and
other professional expenses, the expenses of Buyer’s due diligence review and other expenses
incurred by Buyer in connection herewith and not expressly allocated hereunder, provided Buyer
shall provide supporting documentation for such costs; provided, however, that in no event shall
Seller be required to reimburse Buyer for expenses in excess of $150,000 in the aggregate.
Notwithstanding the foregoing, if the Reimbursement Guaranties are not all transferred, or
replacement guaranties are not issued (through a financial institution that is reasonably
acceptable to Buyer) to replace all the Reimbursement Guaranties, to Buyer at the Closing, Seller
shall pay $450,000 to Buyer at the Closing, superseding Seller’s reimbursement obligations in the
immediately preceding sentence above and, from and after the Closing, Seller shall have no further
obligations under this Section 11.11. Notwithstanding anything in this Agreement to the contrary,

transfer or convey any of the Reimbursement Guaranties to Buyer (or to obtain replacements thereof)
except for the payment expressly set forth in the immediately preceding sentence.

     11.12 Further Assurances. Seller, on the one hand, and Buyer, on the other hand, at any time
after the Closing Date, will promptly execute, acknowledge and deliver any further deeds,
assignments, conveyances and other assurances, documents and instruments of transfer, reasonably
requested by the other parties and necessary to comply with the representations, warranties and
covenants contained herein and will take any action consistent with the terms of this Agreement
that may reasonably be requested by the other parties for the purpose of assigning, transferring,
granting, conveying, vesting and confirming ownership in or to Buyer, or reducing to Buyer’s
possession, any or all of the Assets or effecting the assumption of the Assumed Contracts.

     11.13 No Third Party Beneficiary. Any agreement to perform any obligation or pay any amount
and any assumption of any obligation herein contained, express or implied, shall be only for the
benefit of the parties hereto and their respective successors and permitted assigns as expressly
permitted in this Agreement, and such agreements and assumptions shall not inure to the benefit of
any obligee, whomever, it being the intention of the undersigned that no one shall be or be deemed
to be a third party beneficiary of this Agreement other than parties that may have a right to
indemnification under this Agreement.

     11.14 Limitation of Liability. The parties hereto expressly acknowledge and agree that no
party hereto shall have any liability under any provision of this Agreement for any punitive,
incidental, consequential, special or indirect damages, including business interruption, diminution
