                                   ARTICLE 2
                       SALE AND PURCHASE OF COMPANY SHARES

         2.1      Sale and Purchase of Company Shares. Upon the terms and
subject to the conditions of this Agreement, at the Closing, the Seller Parties
will cause El Dorado to sell, assign and transfer to Purchaser, and Purchaser
will purchase and acquire from El Dorado, all legal and beneficial right, title
and interest in and to the Company Shares, free and clear of any and all Liens.

         2.2      Purchase Price. The purchase price for the Company Shares will
be cash in the amount of Sixteen Million and no/100 Dollars ($16,000,000.00),
subject to adjustment as determined pursuant to the provisions of Section 2.7
(as adjusted, the "Purchase Price"), payable by Purchaser to El Dorado upon the
terms and subject to the conditions of this Agreement.

         2.3      Preliminary Merger. As promptly as practicable following the
execution of this Agreement, El Dorado will reorganize the ownership structure
of the Company pursuant to a short-form merger under Delaware law (the
"Preliminary Merger") pursuant to which the Company will be merged with a
wholly-owned subsidiary of El Dorado organized for the sole purpose of
effectuating the Preliminary Merger, with the Company being the surviving
entity. Prior to executing and filing any documents necessary or advisable to
effect the Preliminary Merger, the Seller Parties shall provide Purchaser
reasonable opportunity to comment thereon. In connection with the Preliminary
Merger, each record holder of outstanding shares of capital stock of the
Company, other than El Dorado (collectively, the "Minority Shareholders"), will
have his, her or its shares of such stock converted into a right to receive a
specified cash payment from El Dorado. Immediately after giving effect to the
Preliminary Merger, El Dorado will be the legal and beneficial owner of all of
the issued and outstanding shares of capital stock of the post-merger Company
(the "Company Shares"). The Seller Parties will cause to be cancelled all
outstanding warrants issued by the Company and held by the Seller Parties for
the purchase of shares of capital stock of the Company. The Seller Parties agree
that the Minority Shareholders shall be entitled to appraisal rights pursuant to
Section 262 of the Delaware General Corporation Law, and the Seller Parties
agree that they shall be solely liable for any payments required in connection
therewith, as well as all other costs and Liabilities in connection with the
Preliminary Merger.

         2.4      Closing. Upon the terms and subject to the conditions hereof,
the closing of the sale and purchase of the Company Shares as provided herein
(the "Closing") will take place at 10:00 a.m. local time on the second (2nd)
Business Day following the satisfaction or waiver (subject to Applicable Law) of
the conditions precedent specified in Article 7 (other than those conditions
that by their nature are to be fulfilled only at the Closing, but subject to the
fulfillment or waiver (subject to Applicable Law) of such conditions) (the
"Closing Date"), at the offices of Snell & Wilmer L.L.P., One Arizona Center,
400 E. Van Buren, Phoenix, Arizona, or at such other time and place as the
Parties may agree in writing.

         2.5      Closing Deliveries by the Seller Parties. At the Closing, the
Seller Parties will deliver or cause to be delivered to Purchaser the following:

                                       13


         2.7      Net Working Capital Determination. The Seller Parties and
Purchaser will determine (i) the amount, if any, by which the Net Working
Capital is a positive amount, and (ii) the amount, if any, by which the Net
Working Capital amount is a negative amount (the amount described in clause (i)
or (ii), the "Working Capital Adjustment"), the determination and payment
thereof to be made as follows:

                  (a)      At least five (5) Business Days before the Closing
         Date, the Seller Parties and Purchaser, acting in good faith, will
         agree upon a mutually acceptable estimate of the Net Working Capital
         based on the most currently available month-end financial records of
         the Company and the Subsidiary and other appropriate information (the
         "Estimated Working Capital Adjustment"). If the Estimated Working
         Capital Adjustment is a positive amount, the Purchase Price payable at
         the Closing will be increased by such amount, and, if the Estimated
         Working Capital Adjustment is a negative amount, the Purchase Price
         payable at the Closing will be decreased by such amount, in each case
         pursuant to Section 2.6(d).

                  (b)      Within forty-five (45) days after the Closing Date,
         Purchaser will deliver to the Seller Parties written notice (the
         "Adjustment Notice") of Purchaser's post-closing determination of the
         Net Working Capital (the "Post-Closing Net Working Capital
         Determination"), as derived from Purchaser's review of the financial
         and other books and records of the Company and the Subsidiary as of the
         Effective Time and prepared in a manner consistent with GAAP and the
         formula and methodology used for purposes of determining the Estimated
         Working Capital Adjustment. The Adjustment Notice will contain
         reasonable detail as to how the Post-Closing Net Working Capital
         Determination was determined by Purchaser along with copies of any and
         all materials used in preparing the Post-Closing Net Working Capital
         Determination. Within thirty (30) days after the Seller Parties'
         receipt of the Adjustment Notice, the Seller Parties will notify
         Purchaser in writing of the Seller Parties' acceptance or rejection of
         the Post-Closing Net Working Capital Determination as set forth in the
         Adjustment Notice. Any notice of rejection ("Rejection Notice") by the
         Seller Parties must include reasonable detail as to the reasons for
         such rejection and, if appropriate, the Seller Parties' proposed
         calculation of the Post-Closing Net Working Capital Determination. If
         (i) by written notice to Purchaser, the Seller Parties accept the
         Post-Closing Net Working Capital Determination as set forth in the
         Adjustment Notice, or (ii) the Seller Parties fail to deliver any
         notice of acceptance or rejection of the Post-Closing Net Working
         Capital Determination within the prescribed thirty (30)-day period
         (which failure will result in the Seller Parties being deemed to have
         irrevocably accepted and agreed with the Post-Closing Net Working
         Capital Determination), the Post-Closing Net Working Capital
         Determination as set forth in the Adjustment Notice will be final and
         binding on the Parties.

                  (c)      If the Seller Parties deliver a Rejection Notice to
         Purchaser under Section 2.7(b), the Seller Parties and Purchaser and
         their respective representatives will promptly (and in any event within
         ten (10) Business Days) attempt in good faith to resolve the
         differences between the Seller Parties and Purchaser as set forth in
         the Rejection Notice. If the Seller Parties and Purchaser are unable to
         resolve such matter within thirty (30) days after the date of delivery
         of the Seller Parties' Rejection Notice to Purchaser, the Seller
         Parties and Purchaser will refer the dispute to a mutually acceptable
         firm of

                                       14



         independent certified public accountants (the "Independent
         Accountants") for review and final determination of the Post-Closing
         Net Working Capital Determination. The Independent Accountants may
         request of the Seller Parties or Purchaser such documents and
         information as may be necessary or appropriate for proper determination
         of the matter, and the Seller Parties and Purchaser will cooperate to
         promptly satisfy any such request. Any such documents provided to the
         Independent Accountants shall be provided on a confidential basis and
         shall be concurrently provided to the other Parties. The determination
         by the Independent Accountants of the Post-Closing Net Working Capital
         Determination will be final and binding on the Seller Parties and
         Purchaser, and such determination shall be deemed the Post-Closing Net
         Working Capital Determination for purposes of Section 2.7(d). The costs
         of the Independent Accountants in undertaking such review and
         determination will be shared equally by the Seller Parties and
         Purchaser.

                  (d)      Within ten (10) Business Days after the date of the
         final agreement of the Seller Parties and Purchaser, the final
         determination by the Independent Accountants or the deemed acceptance
         by the Seller Parties (as the case may be) of the Post-Closing Net
         Working Capital Determination (such date, the "Determination Date"),
         either:

                           (i)      Purchaser will pay to El Dorado by wire
                  transfer of immediately available U.S. funds the amount (if
                  any) by which the Post-Closing Net Working Capital
                  Determination exceeds the Estimated Working Capital
                  Adjustment; or

                           (ii)     The Seller Parties will pay to Purchaser by
                  wire transfer of immediately available U.S. funds the amount
                  (if any) by which the Estimated Working Capital Adjustment
                  exceeds the Post-Closing Net Working Capital Determination.

                  financial condition, results of operation, assets,
                  Liabilities, reserves, business, operations or prospects; or

                           (xi)    incurred any Liability (other than pursuant
                  to agreements entered into in the ordinary course of business

         Party nor APS is party to or bound by any decree, order, injunction,

         set forth on Schedule 4.12(c), (i) all certifications and

         in its industry. The Company has provided to Purchaser accurate and
         complete copies of all policies of insurance (including riders and
         amendments thereto) obtained by the Company, the Subsidiary or any of
         their Affiliates to which the Company or the Subsidiary is a party or
         under which the Company or the Subsidiary is covered as of the date
         hereof, each of which is identified on Schedule 4.13(a). All such
         policies are in full force and effect, all premiums due thereon have
         been paid, the Company and the


                                       27



         Subsidiary are otherwise in compliance in all material respects with
         the terms and provisions of such policies, and adequate reserves have
         been taken in accordance with GAAP for potential losses for which the
         Company or the Subsidiary would be financially responsible under the
         terms and provisions of such policies.

                  (b)      Schedule 4.13(b) contains a complete summary
         description dating back to January 1, 2000 of (i) the loss experience
         under each such policy of insurance, including a statement describing
         each claim having a value in excess of Fifty Thousand Dollars ($50,000)

         the loss experience for all claims during such period that were
         self-insured by the Company or the Subsidiary, including the number and
         aggregate cost of such claims. None of the Seller Parties, the Company
         nor the Subsidiary has received any written notice of cancellation or
         termination with respect to any insurance policy of the Company or the
         Subsidiary or under which the Company or the Subsidiary is covered, and
         none of the Seller Parties, the Company nor the Subsidiary has received
         notice from any of the Company's or the Subsidiary's insurance carriers
         that any insurance premiums will be increased in the future or that any
         insurance coverage presently provided for will not be available to the
         Company or the Subsidiary in the future on substantially the same terms
         as now in effect.

                  (c)      The maximum level of insurance coverage maintained
         by the Company and the Subsidiary is as set forth in Schedule 4.13(c),
         and such coverage is adequate to cover, and each of the Company and the
         Subsidiary is otherwise in compliance with, all material insurance
         requirements imposed thereon under contracts or other agreements to
         which the Company or the Subsidiary is a party.

         4.14     Title to Assets. Except as set forth on Schedule 4.14, the
Company and the Subsidiary have good, clear, record, and marketable or insurable
title to their assets and properties, free and clear of any and all Liens, other

         4.15     Sufficiency of Assets. The real and personal property of the
Company and the Subsidiary constitute all of the assets (tangible and
intangible) necessary for the continued conduct of the Company's and the
Subsidiary's businesses after the Closing in substantially the same manner as
presently being conducted.

         4.16     Condition of Facilities and Equipment. The facilities, plants,
machinery and equipment of the Company and the Subsidiary are in good working
order and condition, ordinary wear and tear excepted, and are being operated and

         4.17     Accounts Receivable. (i) All accounts receivable of the
Company and the Subsidiary reflected in the Financial Statements have arisen
only from bona fide transactions in the ordinary course of business, and (ii) to
the Knowledge of the Seller Parties, there are no facts or circumstances (other
than general social and economic conditions) which would result in any material
increase in the uncollectibility of such receivables in excess of the reserves
of $139,945 therefor reflected in the Financial Statements.


                                       28

                  Intellectual Property items listed in Schedule 4.19(a) and own
                  or have the right to use all Intellectual Property used in the
                  business as currently conducted, except where the failure to
                  possess such right would not, individually or in the
                  aggregate, reasonably be expected to have a Material Adverse
                  Effect;

                           (ii)    except as would not, individually or in the

                  filing, examination and maintenance fees, proofs of working or
                  use, timely post-registration filing of affidavits of use and

         4.24     Benefit Plans.

                  (a)      Schedule 4.24(a) sets forth a list of each Benefit
         Plan as of the date hereof. With respect to each Benefit Plan, the
         Seller Parties have made available to Buyer:

                           (i)     a copy of each Benefit Plan (including all
                  amendments thereto);

                           (ii)    a copy of the annual report and actuarial
                  report, if required under ERISA or the Code, with respect to
                  each Benefit Plan for the last two (2) plan years ending prior
                  to the date hereof;

                           (iii)   if the Benefit Plan is funded through a trust
                  or any Third Party funding vehicle, a copy of the trust or
                  other funding agreement (including all amendments thereto) and
                  the latest financial statements with respect to the last
                  reporting period ended immediately prior to the date thereof;

                           (iv)    a copy of the most recent Summary Plan
                  Description, together with each Summary of Material
                  Modifications, if required under ERISA, with respect to each
                  Benefit Plan; and


                                       33


                           (v)     the most recent determination letter
                  received from the IRS with respect to each Benefit Plan that
                  is intended to be qualified under Section 401(a) of the Code.

                  (b)      No Liability under Title IV of ERISA has been
         incurred by the Company, the Subsidiary or any ERISA Affiliate since
         the effective date of ERISA that has not been satisfied in full, and no
         condition exists that presents a material risk to the Company or the
         Subsidiary of incurring any Liability under Title IV of ERISA, other
         than Liability for premiums due to the Pension Benefit Guaranty
         Corporation. To the extent that the representation in this subsection
         (b) applies to Section 4064, 4069 or 4204 of ERISA, it is made not only
         with respect to the Employee Plans but also with respect to any
         employee benefit plan, program, agreement or arrangement subject to
         Title IV of ERISA to which the Company, the Subsidiary or any ERISA
         Affiliate made, or was required to make, contributions during the
         five-year period ending on the Closing Date.

                  (c)      The Pension Benefit Guaranty Corporation has not
         instituted proceedings to terminate any Employee Plan and no condition
         exists that presents a material risk that such proceedings will be
         instituted. Any contribution or premium required to be paid to or in
         respect of an Employee Plan under the terms of the Employee Plan,
         Section 302 of ERISA or Section 412 of the Code, have, to the extent
         due, been paid in full or properly recorded on the financial statements
         or records of the Company, the Subsidiary or an ERISA Affiliate, and no
         Employee Plan or any trust established thereunder currently has any
         "accumulated funding deficiency" (as defined in Section 302 of ERISA or
         Section 412 of the Code), whether or not waived. The present value of
         the projected benefit obligations under each Benefit Plan subject to
         Title IV of ERISA, determined upon the basis of the actuarial
         assumptions used for funding purposes in the most recent actuarial
         report prepared with respect to such Benefit Plan, did not, as of its
         most recent valuation date, exceed the then current value of the assets
         of such Benefit Plan allocable to such projected benefit obligations.

                  (d)      No Benefit Plan is a multiemployer plan (within the
         meaning of Section 3(37) or 4001(a)(3) of ERISA).

                  (e)      Each Benefit Plan has been operated and administered
         in all material respects in accordance with its terms and Applicable
         Laws, including ERISA and the Code. There are no pending (or, to the
         Seller Parties' Knowledge, threatened) claims involving the Benefit
         Plans (other than routine claims for benefits). A favorable opinion
         letter from the IRS regarding qualification of the form of a Benefit
         Plan under all currently effective provisions of Section 401(a) of the
         Code (except for requirements for which the remedial amendment period
         has not passed) has been received by the prototype plan sponsor for
         each Benefit Plan that is intended to be "qualified" within the meaning
         of Section 401(a) of the Code, and, to the Knowledge of the Seller
         Parties, no facts exist that would reasonably be expected to result in
         the revocation of any such opinion letter.

                  (f)      Except as may be provided in any Employment Contract
         or as set forth on Schedule 4.24(f), the consummation of the
         transactions contemplated by this Agreement will not, either alone or
         in combination with any other event, (i) result in any payment


                                       34



         becoming due, or increase the amount of compensation due, to any
         Employee or former employee or current or former director of the
         Company or the Subsidiary, (ii) increase any benefits payable under any
         Benefit Plan, or (iii) accelerate the time of payment or vesting, or
         increase the amount of, or otherwise enhance, any benefit due to any
         Employee or former employee or current or former director of the
         Company or the Subsidiary.

                  (g)      No Benefit Plan provides benefits, including death or
         medical benefits (whether or not insured), with respect to current or
         former employees after retirement or other termination of service
         (other than (i) coverage mandated by Sections 601-608 of ERISA and
         Section 4980F(g) of the Code, (ii) death benefits or retirement
         benefits under any employee pension benefit plan (within the meaning of
         Section 3(2) of ERISA), (iii) benefits the full cost of which is borne
         by the current or former employee (or his or her beneficiary), (iv)
         deferred compensation benefits accrued as Liabilities on the books of
         the Company, the Subsidiary or an ERISA Affiliate, or (v) severance
         benefits under Employment Contracts).

                  (h)      To the Knowledge of the Seller Parties, no
         representations or communications, oral or written, with respect to the
         participation, eligibility for benefits, vesting, benefit accrual or
         coverage under any Employee Plan have been made to any Employee or any
         former employee or current or former director of the Company or the
         Subsidiary (or any of their respective representatives or
         beneficiaries) which are not in accordance with the terms and
         conditions of the Employee Plans.

                  (i)      Except as disclosed on Schedule 4.24(i), no leased
         employee (within the meaning of Section 414(n) of the Code) performs
         (or during the preceding three (3) years performed) services for the
         Company or the Subsidiary; each of the Company and the Subsidiary has
         at all times been in material compliance with Applicable Laws regarding
         the classification of employees and independent contractors; and no
         person engaged by the Company or the Subsidiary as an independent
         contractor, third party contract laborer, temporary employee, or
         "leased employee" has ever been improperly excluded from participation
         in a Benefit Plan, nor has the Company or the Subsidiary used the
         services of such individuals to an extent that would reasonably be
         expected to result in the disqualification of any of the Employee Plans
         or the imposition of material penalties or excise taxes with respect to
         the Employee Plans by the IRS, the Department of Labor, the Pension
         Benefit Guaranty Corporation, or any other Governmental Authority.

                  (j)      Except as required by Applicable Law or as described
         on Schedule 4.24(j), since January 1, 2004, there has been no amendment
         to, written interpretation or announcement (whether or not written) by
         the Company, the Subsidiary or any ERISA Affiliate relating to, or
         change in employee participation or coverage under, any Benefit Plan
         that would increase the expense of maintaining such Benefit Plan above
         the level of the expense incurred in respect thereof for the preceding
         twelve (12) months.

                  (k)      With respect to each of the Benefit Plans, the
         provisions of Section 4980B(f) of the Code and Sections 601-609 of
         ERISA and the provisions of the Health


                                       35

         adversely affect the conduct of the Company's or the Subsidiary's

         Certificates of Compliance filed by or on behalf of the Company or the
         Subsidiary are in material compliance with NRC regulations. To the
         Seller Parties' Knowledge, there are no facts or circumstances
         reasonably likely to result in the Company or the Subsidiary failing to
         receive NRC approval of any such amendments.

         4.29     New Technology. The Seller Parties have disclosed to
Purchaser all facts Known to them material to the Subsidiary's proposed "new

Knowledge of the Seller Parties, the New Cask Technology does not and will not
infringe, dilute, misappropriate or otherwise violate any Intellectual Property
right of any other Person, and it has not been alleged to do so. The Seller
Parties do not have any Knowledge of facts or circumstances that would likely
result in the New Cask Technology failing to operate in the manner described to

         for such Party to enforce its rights under this Agreement or any other
         agreement or instrument delivered by or to such Party pursuant to this
         Agreement, or (iv) such information is already in the public domain
         other than as a result of a breach of this Section 6.3(a) or any other
         confidentiality or non-disclosure obligation owed to any Party by any
         Person (including any other Party); provided further that to the extent
         feasible, prior to disclosing any such information to a Third Party
         pursuant to clause (i) or (iii) above, a Party shall notify the other
         Parties of the proposed disclosure and use its commercially reasonable
         efforts to obtain from the Third Party reliable assurance that such
         information will be accorded confidential treatment.

                  (b)      With respect to any initial public announcement of
         the consummation of the transactions contemplated hereby, the Parties
         will use their reasonable best efforts to reach agreement on the
         contents and timing thereof and, with respect to any subsequent
         announcement, through the six-month anniversary of the Closing Date, or
         any announcement relating to any litigation brought by Minority
         Shareholders, at any time, each Party will (i) consult with the other
         Parties with respect to the contents of such announcement, (ii) provide
         the other Parties reasonable opportunity to comment thereon, and (iii)
         use reasonable efforts to incorporate any such comments. However, such
         requirements for cooperation will not serve to delay any Party from
         making any such required public announcement within any specific time
         period mandated by Applicable Law or otherwise on a timely basis.

         6.4      Tax Matters.

                  (a)      Filing of Tax Returns for Periods Through Closing
         Date.

                           (i)     The Seller Parties will accurately complete
                  and file or cause to be completed and filed on a timely basis
                  all (A) affiliated, combined, consolidated or unitary Tax
                  Returns that include the Seller Parties or any of their
                  Affiliates, and (B) Tax Returns of the Company or the
                  Subsidiary, for any taxable period that ends on or before the
                  Closing Date. For all periods that end on or before the
                  Closing Date, Parent will include the Company and the
                  Subsidiary in Parent's consolidated federal income Tax
                  Return(s). Parent will include the income of the Company and
                  the Subsidiary (including any deferred items triggered into
                  income under Treasury Regulation Section 1.1502-13 and any
                  excess loss account taken into income under Treasury
                  Regulation Section 1.1502-19) on Parent's consolidated federal
                  income Tax Returns for all periods falling within the
                  Pre-Closing Tax Period. All income Tax Returns to be filed by
                  the Seller Parties pursuant to this Section 6.4(a)(i) will be
                  prepared and filed in a manner consistent with the Seller
                  Parties' prior practice, except for accounting method changes
                  that do not relate to any Company or Subsidiary Tax Return
                  item and except as required by any change in


                                       43



                  Applicable Law. The Seller Parties shall use reasonable
                  efforts to consult Purchaser if the Seller Parties propose to
                  file a Tax Return pursuant to this Section that includes a tax
                  position not previously taken if such action could have a
                  material adverse impact on Purchaser, any Affiliate of
                  Purchaser, the Company or the Subsidiary.

                           (ii)    Purchaser will, except to the extent that
                  such Tax Returns are the responsibility of the Seller Parties
                  pursuant to Section 6.4(a)(i), prepare or cause to be
                  prepared, and timely file or cause to be timely filed, all Tax
                  Returns of the Company or the Subsidiary with respect to
                  Straddle Periods. At least ten (10) days prior to the due date
                  for the payment of a Tax with respect to a Straddle Period,
                  Purchaser shall deliver to the Seller Parties a written
                  calculation of the Seller Parties' share of such Tax (in
                  accordance with Section 6.4(b)) and the Tax Return relating to
                  such Tax, and at least five (5) days prior to the due date for
                  payment of such Tax, the Seller Parties will pay Purchaser the
                  amount of Taxes shown on such Tax Returns that relate to the
                  portion of the Straddle Period through the end of the Closing
                  Date (as determined in accordance with Section 6.4(b));
                  provided, however, that the failure of Purchaser to make such
                  timely delivery shall not relieve the Seller Parties of any of
                  their obligations with respect to Taxes and indemnity
                  obligations therefor under the Tax Provisions, except to the
                  extent that the Seller Parties are actually prejudiced
                  thereby. Purchaser's calculation of the Seller Parties' share
                  of such a Tax for a Straddle Period shall be subject to
                  approval of the Seller Parties.

                           (iii)   Purchaser will cause the Company and the
                  Subsidiary to file income Tax Returns or will include the
                  Company and the Subsidiary in Purchaser's affiliated,
                  combined, unitary or consolidated income Tax Returns, for all
                  periods other than periods ending on or before the Closing
                  Date.

                  (b)      Straddle Period. With respect to any Straddle
         Period, the amount of any Taxes payable by or attributable to the
         Company and the Subsidiary based on or measured in whole or in part by
         income or receipts of the Company and the Subsidiary for the
         Pre-Closing Tax Period will be determined based on an interim closing
         of the books as of the close of business on the Closing Date (and for
         such purpose, the taxable period of any partnership or other
         pass-through entity in which the Company or the Subsidiary holds a
         beneficial interest will be deemed to terminate at such time). The
         amount of other Taxes attributable to or payable by the Company or the
         Subsidiary for a Straddle Period which relates to the Pre-Closing Tax
         Period will be deemed to be the amount of such Tax for such Straddle
         Period multiplied by a fraction, the numerator of which is the number
         of days in the taxable period ending on (and including) the Closing
         Date and the denominator of which is the number of days in such
         Straddle Period.

                  (c)      Tax Indemnification.

                           (i)     The Seller Parties shall pay or cause to be
                  paid, shall be jointly and severally liable for, and shall
                  indemnify, defend and hold Purchaser and its Affiliates
                  (including the Company and the Subsidiary after the Closing
                  Date)


                                       44



                  harmless from and against any and all (A) Taxes of the Company
                  and the Subsidiary for any Pre-Closing Tax Period, (B) Taxes
                  of the Seller Parties imposed on the Company or the Subsidiary
                  under Treasury Regulation Section 1.1502-6 (or any similar
                  provision of state, local or foreign Tax law) by reason of the
                  Company or the Subsidiary having been a member of any
                  affiliated, consolidated, combined, or unitary group on or
                  before the Closing Date, (C) any liability for Taxes as a
                  result of transferee or successor liability or under any Tax
                  Sharing Agreement, (D) any liability for Taxes as a result of
                  any breach of any representation or warranty made by the
                  Seller Parties in Section 4.9, and (E) Transfer Taxes
                  resulting from the transactions contemplated by this Agreement
                  pursuant to Section 6.4(j).

                           (ii)    Payment in full of any amount due from the
                  Seller Parties under this Section 6.4(c) shall be made to
                  Purchaser in immediately available funds at least two (2)
                  Business Days before the date payment of the Taxes to which
                  such payment relates is due, or, if no Tax is payable, within
                  fifteen (15) days after written demand is made for such
                  payment.

                  (d)      Tax Contests.

                           (i)     If any Taxing Authority asserts a Tax Claim,
                  then the Party hereto first receiving notice of such Tax Claim
                  shall promptly provide written notice thereof to the other
                  Party or Parties hereto; provided, however, that the failure
                  of such Party to give such prompt notice shall not relieve the
                  other Party of any of its obligations with respect to Taxes
                  and indemnity obligations therefor under the Tax Provisions,
                  except to the extent that the other Party is actually
                  prejudiced thereby. Such notice shall specify in reasonable
                  detail, to the extent known, the basis for such Tax Claim and
                  shall include a copy of the relevant portion of any
                  correspondence received from the Taxing Authority.

                           (ii)    The Seller Parties shall have the right and
                  obligation to control, at their own expense, any audit,
                  examination, contest, litigation or other proceeding by or
                  against any Taxing Authority (a "Tax Proceeding") in respect
                  of the Company or the Subsidiary for any taxable period that
                  ends on or before the Closing Date; provided, however, that,
                  in the event of any Tax Claim in excess of One Thousand
                  Dollars ($1,000), (A) the Seller Parties shall provide
                  Purchaser with a timely and reasonably detailed account of
                  each stage of such Tax Proceeding, (B) the Seller Parties
                  shall use reasonable efforts to consult with Purchaser before
                  taking any significant action in connection with such Tax
                  Proceeding, (C) the Seller Parties shall use reasonable
                  efforts to consult with Purchaser and offer Purchaser an
                  opportunity to comment before submitting any written materials
                  prepared or furnished in connection with such Tax Proceeding,
                  (D) the Seller Parties shall defend such Tax Proceeding
                  diligently and in good faith as if they were the only party in
                  interest in connection with such Tax Proceeding, (E) Purchaser
                  shall be entitled to participate, at its own expense, in such
                  Tax Proceeding and receive copies of any written materials
                  relating to such Tax Proceeding received from the relevant
                  Taxing Authority, and (F) the Seller


                                       45



                  Parties shall not settle, compromise or abandon any issues
                  relating to such Tax Proceeding, if such action could have a
                  materially adverse impact on Purchaser or any Affiliate of
                  Purchaser (including the Company and the Subsidiary after the
                  Closing Date), without obtaining the prior written consent of
                  Purchaser.

                           (iii)   In the case of a Tax Proceeding for a
                  Straddle Period of the Company and the Subsidiary, Purchaser
                  shall have the right to control, at its own expense, such Tax
                  Proceeding; provided, however, that (A) Purchaser shall
                  provide the Seller Parties with a timely and reasonably
                  detailed account of each stage of such Tax Proceeding, (B)
                  Purchaser shall use reasonable efforts to consult with the

                  connection with such Tax Proceeding, (C) Purchaser shall use
                  reasonable efforts to consult with the Seller Parties and
                  offer the Seller Parties an opportunity to comment before
                  submitting any written materials prepared or furnished in
                  connection with such Tax Proceeding, (D) Purchaser shall
                  defend such Tax Proceeding diligently and in good faith as if
                  it were the only party in interest in connection with such Tax
                  Proceeding, (E) the Seller Parties shall be entitled to
                  participate, at their own expense, in such Tax Proceeding and
                  receive copies of any written materials relating to such Tax
                  Proceeding received from the relevant Taxing Authority, and
                  (F) Purchaser shall not settle, compromise or abandon any such
                  Tax Proceeding, if such action could have a materially adverse
                  impact on the Seller Parties or any Affiliate of the Seller
                  Parties, without obtaining the prior written consent of the
                  Seller Parties.

                  (e)      Purchaser Consolidated Returns. Notwithstanding any
         other provision of this Agreement, (i) Purchaser shall be entitled to
         control in all respects, and none of the Seller Parties, nor any

         Purchaser and its Affiliates shall not be required to provide any
         Person with any affiliated, consolidated, combined or unitary Tax

         to the extent that such Tax Returns would be required to be delivered
         but for this Section 6.4(e), the person that would be required to
         deliver such Tax Returns shall instead deliver pro forma Tax Returns
         relating solely to the Company or the Subsidiary).

                  (f)      Seller Party Consolidated Returns. Notwithstanding
         any other provision of this Agreement, (i) the Seller Parties shall be
         entitled to control in all respects, and neither Purchaser nor any of
         its Affiliates shall be entitled to participate in, any Tax Proceeding
         with respect to any affiliated, consolidated, combined or unitary Tax
         Return that includes the Seller Parties, and (ii) the Seller Parties
         shall not be required to provide any Person with any affiliated,

         deliver such Tax Returns shall instead deliver pro forma Tax Returns
         relating solely to the Company and/or the Subsidiary).


                                       46


                  (g)      Cooperation. Each Party hereto shall provide to the
         other Party hereto such cooperation, documentation and information as
         either of them reasonably may request in (i) filing any Tax Return,
         amended Tax Return or claim for refund, (ii) determining a liability
         for Taxes or an indemnity obligation therefor under the Tax Provisions
         or a right to refund of Taxes, (iii) conducting any Tax Proceeding,
         (iv) determining an allocation of Taxes between a Pre-Closing Tax
         Period and Post-Closing Tax Period or (v) understanding the financial
         and tax accounting of the Seller Parties for the Company and the
         Subsidiary with respect to any Pre-Closing Tax Period or Straddle
         Period. Such cooperation, documentation and information shall include
         providing copies of all relevant portions of relevant Tax Returns,
         together with all relevant portions of relevant accompanying schedules
         and relevant work papers, relevant documents relating to rulings or
         other determinations by Taxing Authorities and relevant records
         concerning the ownership and Tax basis of property and other
         information, which any such Party may possess or control. Each Party
         will retain all Tax Returns, schedules and work papers, and all
         material records and other documents relating to Tax matters, of the
         relevant entities for their respective Tax periods ending on or prior
         to the Closing Date until the later of (x) the expiration of the
         statute of limitations for the Tax periods to which the Tax Returns and
         other documents relate or (y) eight (8) years following the due date
         (without extension) for such Tax Returns. Thereafter, the Party holding
         such Tax Returns or other documents may dispose of them after offering
         the other Party reasonable notice and opportunity to take possession of
         such Tax Returns and other documents at such other Party's own expense.
         Each Party shall make its employees reasonably available on a mutually
         convenient basis at its cost to provide explanation of any documents or
         information so provided.

                  (h)      Tax Sharing Agreements. Anything in any other
         agreement to the contrary notwithstanding, all liabilities and
         obligations between the Seller Parties or any of their Affiliates
         (other than the Company or the Subsidiary) on the one hand and the
         Company or the Subsidiary on the other hand, under any Tax Sharing
         Agreement in effect prior to the Closing Date (other than this
         Agreement) that are not paid or satisfied at or prior to the Closing
         shall cease and terminate as of the Closing Date as to all past,
         present and future taxable periods.

                  (i)      Tax Treatment.

                           (i)     The Seller Parties, the Company, and the
                  Subsidiary, and each of their respective Affiliates shall
                  treat any and all payments under Sections 2.7(d), 6.4(c),
                  6.4(k), or Article 9 as an adjustment to the Purchase Price to
                  the maximum extent permitted by applicable Tax laws.

                           (ii)    Neither Purchaser nor the Seller Parties
                  shall make or file any election under Code Section 338(h)(10)
                  (or any similar provision of the law of any state or other
                  taxing jurisdiction) with respect to the sale of the Company
                  Shares (or the acquisition of shares in the Subsidiary)
                  pursuant to this Agreement. For purposes of all Tax Returns
                  and other applicable filings, the Seller Parties and Purchaser
                  will report the transactions contemplated hereby as a sale of
                  the Company Shares.


                                       47



                  (j)      Survival of Obligations. Notwithstanding anything in
         this Agreement to the contrary, (i) the obligations of the Parties set
         forth in the Tax Provisions with respect to Taxes and indemnity
         obligations therefor shall not be subject to any restrictions or
         limitations of any kind other than as expressly set forth in the Tax
         Provisions and shall survive the Closing, and (ii) the representations
         and warranties in Section 4.9 with respect to Taxes and indemnity
         obligations therefor shall survive, until thirty (30) days after the
         expiration of all applicable statutes of limitations (giving effect to
         any extensions or waivers thereof).

                  (k)      Transfer Taxes. All Transfer Taxes that are payable
         or that arise as a result of the consummation of the transactions
         contemplated by this Agreement shall be borne by the Seller Parties.
         The Seller Parties will prepare any Tax Returns that must be filed in
         connection with any Transfer Taxes and will provide a copy to Purchaser
         for its comment and approval.

                  (l)      Approvals, Consents, etc. To the extent that the law
         places such responsibility on Purchaser and solely to the extent set
         forth on Schedule 6.4(l), Purchaser shall obtain material approvals,
         Consents, licenses, Permits, waivers or authorizations relating to
         Taxes or Tax Returns, and shall make filings with respect thereto, in
         connection with the consummation of the transactions contemplated by
         this Agreement. Except as provided pursuant to the preceding sentence,
         the Seller Parties shall obtain all material approvals, Consents,
         licenses, Permits, waivers or authorizations relating to Taxes or Tax
         Returns, and shall make all filings with respect thereto, in connection
         with the consummation of the transactions contemplated by this
         Agreement.

                  (m)      Dispute Resolution. In the event that the Seller
         Parties and Purchaser disagree as to the amount or calculation of any
         payment to be made under this Agreement relating to Taxes, or the
         interpretation or application of any provision under this Agreement
         relating to Taxes, the Parties shall attempt in good faith to resolve
         such dispute. If such dispute is not resolved within sixty (60) days
         following the commencement of the dispute, the Seller Parties and
         Purchaser shall jointly retain a nationally recognized law or
         accounting firm, which firm is independent of both Parties (the
         "Independent Firm"), to resolve the dispute. The Independent Firm shall
         act as an arbitrator to resolve all points of disagreement and its
         decision shall be final and binding upon all Parties involved.
         Following the decision of the Independent Firm, the Seller Parties and
         Purchaser shall each take or cause to be taken any action necessary to
         implement the decision of the Independent Firm. The fees and expenses
         relating to the Independent Firm shall be borne fifty percent (50%) by
         the Seller Parties and fifty percent (50%) by Purchaser.

                  (n)      Coordination. Notwithstanding anything in this
         Agreement to the contrary, in the event there is a conflict between the
         Tax Provisions and any other provision contained in this Agreement, the
         Tax Provisions shall control.


                                       48


         6.5      Employment Matters.

                  (a)      The Company and the Subsidiary are and have been in
         material compliance with all notice and other requirements under the
         WARN Act. The Seller Parties shall not, and shall cause the Company and
         the Subsidiary not to, at any time ninety (90) days before the Closing
         Date, without complying fully with the notice requirements and other
         requirements of the WARN Act, effectuate (i) a "plant closing" as
         defined in the WARN Act affecting any site of employment or one or more
         facilities or operating units within any site of employment of the
         Company or the Subsidiary; or (ii) a "mass layoff" as defined in the
         WARN Act affecting any site of employment of the Company or the
         Subsidiary. In addition, the Seller Parties hereby agree to jointly and
         severally indemnify Purchaser and to defend and hold Purchaser harmless
         from and against any and all claims, losses, damages, expenses,
         obligations and liabilities (including costs of collection, attorney's
         fees and other costs of defense) which Purchaser may incur in
         connection with any suit or claim of violation brought against
         Purchaser under the WARN Act, which relates to actions taken by the
         Company or the Subsidiary with regard to any site of employment or one
         or more facilities or operating units within any site of employment of
         the Company or the Subsidiary prior to the Closing Date.


                  (b)      On or before the Closing Date, the Seller Parties
         shall cause the Company to provide a list to Purchaser of the name and
         site of employment of any and all of the employees of the Company and
         the Subsidiary who have experienced, or will experience, an "employment
         loss" under the WARN Act within the ninety (90) days prior to the
         Closing Date. Purchaser agrees that, following the Closing, it will
         cause the Company and the Subsidiary to maintain the employment of a
         sufficient number of the Company's and the Subsidiary's employees so as
         to preclude any requirement for the giving by the Company or the
         Subsidiary or any of its Affiliates before the Closing of any layoff,
         closing or other termination notice pursuant to the provisions of the
         WARN Act.

                  (c)      Effective not later than immediately before the
         Closing, the Seller Parties shall (i) cause to be transferred to the
         Company or the Subsidiary any assets held (other than assets held by
         the Company, the Subsidiary, or any of their subsidiaries) on or after
         the date hereof in any account where such assets are earmarked or
         reserved for the payment of benefits under a Benefit Plan and (ii)
         cause the Company or the Subsidiary to be treated as the sole settlor
         of any trust whose assets are earmarked or reserved for the payment of
         benefits under a Benefit Plan with all of the rights presently held by
         any settlor thereunder.

         6.6      Payment of Company and Subsidiary Debt Obligations. On or
before the Closing Date, the Seller Parties shall cause the Company or the
Subsidiary to pay or cause to be paid and discharged all outstanding
indebtedness of the Company and the Subsidiary for borrowed money, but excluding
any indebtedness of the Subsidiary to the Company or of the Company to the
Subsidiary; provided, however, that, unless otherwise expressly provided herein,
the Seller Parties will have no obligation to pay or discharge or cause to be
paid or discharged (i) any current account payable or other current liability of
the Company or the Subsidiary that is taken into account in the calculation of
the Net Working Capital Adjustment, (ii) any real estate lease or capital lease
obligation of the Company or the Subsidiary, or (iii) any guaranty, surety,


                                       49


indemnity or similar obligation or other covenant or performance obligation of
the Company or the Subsidiary that arises under or in connection with any
contract (including any Material Contract) to which the Company or the
Subsidiary is party, by which the Company or the Subsidiary is bound or under
which the Company or the Subsidiary receives a direct benefit in connection with
the conduct of the Company's or the Subsidiary's business (other than any
contract or obligation identified on Schedule 6.6). For the avoidance of doubt,
on or before the Closing Date, the Seller Parties shall cause the Company to pay
or cause to be paid and/or discharged all indebtedness identified on Schedule
6.6.

         6.7      No Solicitation.

                  (a)      From the date hereof through the Closing, none of the
         Seller Parties, their Affiliates nor their respective representatives
         (including investment bankers, attorneys and accountants) shall,
         directly or indirectly, enter into, solicit, initiate or continue any
         discussions or negotiations with, or encourage or respond to any
         inquiries or proposals by, or participate in any negotiations with, or
         provide any information to, or otherwise cooperate in any other way
         with, any Person, concerning any sale of all or a portion of the
         Company or the Subsidiary, or of any shares of capital stock of the
         Company or the Subsidiary or any merger, consolidation, liquidation,
         dissolution or similar transaction involving the Company or the
         Subsidiary, except the Preliminary Merger (each such transaction being
         referred to herein as a "Proposed Acquisition Transaction") other than
         with (i) Purchaser and its representatives, or (ii) as required by
         Applicable Law. None of the Seller Parties, the Company nor any of
         their Affiliates shall, directly or indirectly, through any officer,
         director, employee, representative, agent or otherwise, solicit,
         initiate or encourage the submission of any proposal or offer from any
         Person (including a "person" as defined in Section 13(d)(3) of the
         Exchange Act) relating to any Proposed Acquisition Transaction. Each of
         the Seller Parties represents that neither it nor the Company nor the
         Subsidiary is directly or indirectly now engaged in discussions or
         negotiations with any Person other than Purchaser with respect to any
         of the foregoing.

                  (b)      The Seller Parties shall promptly notify Purchaser if
         any discussions or negotiations are sought to be initiated, any inquiry
         or proposal is made, or any information is requested with respect to
         any Proposed Acquisition Transaction and notify Purchaser of the
         identity of the prospective purchaser or soliciting party and any other
         information relating to such inquiry or proposal Known to the Seller
         Parties, subject to any confidentiality agreements to which the Seller
         Parties, the Company or the Subsidiary are party as of the date of the
         Exclusivity Agreement, dated as of April 13, 2004, between Purchaser
         and El Dorado.

         6.8      Non-Competition; No Solicitation of Employees.

                  (a)      Each of the Seller Parties agrees that effective upon
         the Closing it will not, for a period of five (5) years following the
         Closing Date, either directly or indirectly, through any subsidiary or
         otherwise, engage in any business similar to or which competes with the
         business of the Company or the Subsidiary as conducted as of the date
         hereof and the Closing Date, including, but not limited to, the
         licensing of, and manufacture and sale of products incorporating, the
         New Cask Technology.


                                       50


                  (b)      For a period of two (2) years following the Closing
         Date, none of the Seller Parties or their subsidiaries shall, directly
         or indirectly, solicit for employment or otherwise solicit the services
         of any of the officers, senior managers or key employeeS of the Company
         or the Subsidiary as of the Closing Date; provided, however, that this
         non-solicitation covenant shall not cover any officer, senior manager,
         or key employee (i) terminated or otherwise released by the Company or
         the Subsidiary from the date of such termination or release or (ii) who
         contacts any of the Seller Parties or their subsidiaries on his or her
         own initiative and without any solicitation by any of the Seller
         Parties or their subsidiaries.

         6.9      Termination of Affiliate Contracts. Except as set forth on
Schedule 6.9 and except as agreed to in writing by the Seller Parties and
Purchaser, all contracts, agreements or arrangements between the Company or the
Subsidiary, on the one hand, and any Affiliates of the Company or the
Subsidiary, on the other, including any agreements or understandings (written or
oral) with respect thereto, shall terminate simultaneously with the Closing
without any further action or liability on the part of the parties thereto or be
terminated by the Seller Parties and other parties thereto on or prior to the
Closing Date.

         6.10     Change of Control Arrangements.

                  (a)      Prior to the Effective Time, the Seller Parties shall
         cause the Company and/or the Subsidiary (as applicable) to amend the
         Second Amended Employment Agreement, dated July 1, 2004, with Peter J.
         Walier, to provide that, as of the Effective Time, one of the Seller
         Parties, and not the Company or the Subsidiary, shall be liable to Mr.
         Walier for any 2004 Retention Bonus (as defined therein) and for any
         Incentive and any Bonus Incentive (each as defined therein) payable
         thereunder in connection with the consummation of the transactions
         contemplated by this Agreement, and the Seller Parties shall make such
         payment pursuant to the Amended Employment Agreement, as so amended.

                  (b)      Purchaser shall be responsible and shall pay or shall
         cause the Company or the Subsidiary to pay any severance-related
         Liabilities of the Company and the Subsidiary to officers and Employees
         of the Company and the Subsidiary that arise under the Employment
         Contracts after the Closing, including any severance-related
         Liabilities arising from the resignations or terminations required by
         Section 2.5(j) hereof.

         6.11     Access to Company and Subsidiary Information. Upon reasonable
notice and subject to Applicable Laws and any confidentiality obligations, the
Seller Parties shall cause the Company and the Subsidiary to afford to the
officers, directors, employees, accountants, counsel, investment bankers,

of Purchaser reasonable access, during normal business hours throughout the
period prior to the Closing Date, to all of the Company's and the Subsidiary's
properties, books, contracts, commitments and records and, during such period,
the Seller Parties shall cause the Company and the Subsidiary to furnish
promptly to Purchaser and its Representatives, (a) access to each report,
schedule and other document filed or received by the Company or the Subsidiary
pursuant to the requirements of Applicable Laws or filed with or sent to any
Governmental Authority and (b) access to all information concerning the Company
or the Subsidiary and their


                                       51



directors and officers and such other matters as may be reasonably requested by
the Purchaser or its Representatives in connection with any filings,
applications or approvals required or contemplated by this Agreement or for any
other reason related to the transactions contemplated by this Agreement.
Purchaser shall, and shall cause its Representatives to, hold in confidence all
documents and information concerning the Company or the Subsidiary furnished to
it in connection with the transactions contemplated by this Agreement. The
Seller Parties shall reasonably cooperate with Purchaser's integration planning
efforts. Without limiting the scope of the cooperation obligation related to Tax
matters under Section 6.4(g), after the Closing Date, the Seller Parties shall
provide Purchaser such supplementary information or documents as Purchaser, the
Company or the Subsidiary may reasonably request in order to understand the
records and information of the Company and the Subsidiary as of the Effective
Time.

         6.12     Use of Company and Subsidiary Name After the Closing. From and
as of the Closing and continuing indefinitely thereafter, the Seller Parties and
their Affiliates shall not use the name "NAC" or "Nuclear Assurance Corporation"
or any similar variation thereof in any business venture or activity. Nothing
herein will prohibit the Seller Parties from using the names "NAC" or "Nuclear
Assurance Company" in any announcements or other descriptions of the
transactions contemplated in this Agreement or in Tax Returns or other filings
with Governmental Authorities.

         6.13     Parent Support Obligations.

                  (a)      Purchaser acknowledges that Parent has entered into
         certain guarantee and indemnity obligations in support of the Company's
         and/or the Subsidiary's obligations to certain of its customers,
         certain of which parent support obligations are described on Schedule
         6.13 (the "Parent Support Obligations"). At the Closing, Purchaser and
         Parent shall enter into an indemnification agreement substantially in
         the form set forth in Exhibit C to this Agreement (the "Indemnification
         Agreement"), pursuant to which Purchaser shall agree to indemnify
         Parent for up to $2 million of any liabilities incurred by Parent under
         the Parent Support Obligations arising out of the performance of the
         Company's and/or the Subsidiary's obligations under the applicable
         customer contracts after the Closing (each such payment an "Indemnity
         Payment").

                  (b)      Following the Closing, neither the Company nor the
         Subsidiary will utilize the General Agreement of Indemnity, dated March
         1, 2001, by and between United States Fire Insurance Company, Parent,
         the Company and the Subsidiary (the "US Fire Indemnity Agreement") for
         any purpose other than to support that certain Agreement, dated April
         27, 1999 between the Subsidiary and APS (as agent for the participants
         in the Arizona Nuclear Power Project) for Supply of Transportable Dry
         Spent Fuel Storage System (Contract No. 500219319) (the "APS
         Agreement") (which does not include, for purposes of this Agreement,
         the amendments thereof dated July 12, 2004 and June 9, 2004). When the
         Subsidiary has received notice of final acceptance of all of its work
         under the APS Agreement, Purchaser and the Seller Parties promptly will
         take all steps necessary to cause the US Fire Indemnity Agreement to be
         terminated and provide Parent with evidence satisfactory to Parent of
         such termination, and Parent will have no further obligation
         thereunder. When the Subsidiary has received notice of final acceptance
         of all of its work under the UMS Hardware Supply Agreement (as such
         term is defined in that


                                       52



         certain Amended and Restated Parent Guarantee, dated April 22, 2003, by
         Parent for the benefit of Maine Yankee Atomic Power Company (the "Maine
         Yankee Guarantee")), Purchaser and the Seller Parties promptly will
         take all steps necessary to cause the Maine Yankee Guarantee to be
         terminated and provide Parent with evidence satisfactory to Parent of
         such termination, and Parent will have no further obligation
         thereunder.

                  (c)      The Seller Parties shall cause the reimbursement and
         indemnity agreements of the Company and the Subsidiary to the Seller
         Parties set forth on Schedule 4.7 and relating to the Parent Support
         Obligations to terminate effective as of the Closing Date.

         by the DOE or the NRC, or their respective staffs, to the operation by
         the Subsidiary of the Nuclear Materials Management and Safeguards
         System database ("NMMSS") after the Closing Date, on such terms and
         conditions, if any, which would not have or reasonably be expected to
         have a Material Adverse Effect (it being understood that terms or
         conditions which materially impact the economic benefit of the
         operation by the Subsidiary of NMMSS after the Closing Date, or that
         require the divestiture, or placement in trust or similar arrangement,
         of the Company, the Subsidiary or any material assets or business
         thereof, would be deemed to be a Material Adverse Effect);

                  (j)      no Proceeding will have been commenced, and be
         continuing, by or on behalf of a Minority Shareholder or relating to
         the Preliminary Merger which has or would reasonably be expected to
         have a Material Adverse Effect or a material adverse effect on
         Purchaser or the transactions contemplated hereby; and

                  (k)      Purchaser shall be reasonably satisfied that there
         has not been, and there is not reasonably likely to be, a materially
         adverse development with respect to the NRC licensing of the New Cask
         Technology, including the timing of completion thereof.

                                   ARTICLE 8
                                   TERMINATION

         8.1      Termination. This Agreement may be terminated at any time
prior to the Closing Date:

                  (a)      by the written agreement of the Seller Parties and
         Purchaser;

                  (b)      by the Seller Parties or Purchaser, by written notice
         to the other, if the transactions contemplated hereby have not been
         consummated pursuant hereto by 5:00 p.m. (New York, New York time) on
         the date that is ninety (90) days from the date hereof (the "Initial
         Termination Date"), unless the failure to close is due to the failure
         of the notifying Party to perform or comply with any of the covenants,
         agreements, or conditions hereof to be performed or complied with by it
         prior to the Closing Date; provided, however, that, if on the Initial
         Termination Date, the condition to Closing set forth in Section 7.2(e),
         Section 7.2(f) or Section 7.2(i) shall not have been fulfilled but all
         other conditions to the Closing shall have been fulfilled or shall be
         capable of being fulfilled, and the applicable Parties are diligently
         pursuing fulfillment of the condition, then the Initial Termination
         Date shall be extended for an additional thirty (30) day period;

                  (c)      by the Seller Parties, by written notice to
         Purchaser, if there shall have been a material breach of any
         representation or warranty, or a material breach of any covenant or
         agreement of Purchaser hereunder, which breach would prevent,
         materially delay or materially impair Purchaser's ability to consummate
         the transactions contemplated by this Agreement, and such breach shall
         not have been remedied within


                                       55


         thirty (30) days after receipt by Purchaser of notice in writing from
         the Seller Parties, specifying the nature of such breach and requesting
         that it be remedied;

                  (d)      by Purchaser, by written notice to the Seller
         Parties, if there shall have been a material breach of any
         representation or warranty, or a material breach of any covenant or
         agreement of the Seller Parties hereunder, which breach would result in
         a Material Adverse Effect, and such breach shall not have been remedied
         within thirty (30) days after receipt by the Seller Parties of notice
         in writing from Purchaser, specifying the nature of such breach and
         requesting that it be remedied; or

                  (e)      by the Seller Parties or Purchaser, by written notice
         to the other, if any Applicable Law is adopted or issued, which has the
         effect, as supported by the written opinion of outside counsel for such
         Party, of prohibiting the Closing, or by any Party if any court of
         competent jurisdiction in the United States or any state shall have
         issued an order, judgment or decree permanently restraining, enjoining
         or otherwise prohibiting the Closing, and such order, judgment or
         decree shall have become final and nonappealable.

         8.2      Effect of Termination. In the event of the termination of this
Agreement pursuant to the provisions of Section 8.1, this Agreement will become
void and have no effect, without any Liability to any Person in respect hereof
or of the transactions contemplated hereby on the part of any Party, or any of
their directors, officers, employees, agents, consultants, representatives,
advisers, stockholders or Affiliates, except, in connection with a termination
pursuant to Section 8.1(c) or Section 8.1(d), for any Liability resulting from
such Party's breach of this Agreement. For the avoidance of doubt, the Parties
agree that, in the event this Agreement is terminated because the transactions
contemplated hereby do not close solely because the condition to closing set
forth in Section 7.2(h) has not been fulfilled, no Party shall have any
Liability to another Party if the Seller Parties shall have used their
commercially reasonable efforts to cause the fulfillment of such condition.
Notwithstanding the foregoing, the provisions of Section 6.3, this Section 8.2,
and Article 10, and the definitions herein applicable to any of such provisions,
will survive termination of this Agreement indefinitely or until the earlier
specified time referred to in such provision.

                                   ARTICLE 9
                          SURVIVAL AND INDEMNIFICATION

         9.1      Survival. All representations, warranties, covenants and
obligations of the Seller Parties and Purchaser contained in this Agreement will
survive the Closing and the consummation of the transactions contemplated
hereby, subject to the provisions of Section 9.5. The waiver by the Seller
Parties or Purchaser of any of their respective conditions for Closing based
upon the accuracy of any representation or warranty of the other Party, or on
the performance of or compliance with any covenant or obligation of the other
Party, will not affect the right to indemnification, reimbursement or other
remedy based upon such representations, warranties, covenants and obligations.

         9.2      Indemnification By the Seller Parties. Subject to the
limitations set forth in this Article 9 and in Section 10.14, the Seller Parties
hereby covenant and agree that, to the fullest extent permitted by Applicable
Law, they will, jointly and severally, defend, indemnify and hold


                                       56



harmless Purchaser, its Affiliates (which, after the Closing, will include the
Company, the Subsidiary and their respective successors) and its and their
respective officers, directors, employees and agents (collectively, the
"Purchaser Indemnitees") for, from and against any and all claims, Liabilities,
obligations, losses, fines, penalties, costs, interest, amounts paid in
settlement of claims, Proceedings, deficiencies or damages (whether absolute,
accrued, conditional, or otherwise) including any out-of-pocket expenses and
reasonable attorneys' fees incurred in the investigation or defense of any of
the same or in asserting any of their respective rights hereunder (each
individually, a "Loss" and collectively, "Losses"), whether or not involving a
Third Party Claim against any Purchaser Indemnitee, resulting from or arising
out of:

                  (a)      any breach or inaccuracy of any representation or
         warranty made by any of the Seller Parties in this Agreement or any
         other agreement and instrument to be executed and delivered by it
         pursuant hereto;

                  (b)      any breach by any Seller Party of any of its
         covenants or obligations hereunder or under any other agreement and
         instrument to be executed and delivered by it pursuant hereto;

                  (c)      the Preliminary Merger or any action initiated by
         Minority Shareholders prior to or after the Closing; and/or

                  (d)      any Reserve Shortfall pursuant to Section 9.7.

         9.3      Indemnification by Purchaser. Subject to the limitations set
forth in this Article 9 and in Section 10.14, Purchaser hereby covenants and
agrees that, to the fullest extent permitted by Applicable Law, it will defend,
indemnify and hold harmless each of the Seller Parties, its Affiliates (which,
before the Closing, will include the Company, the Subsidiary and their
respective successors) and its and their respective officers, directors,
employees and agents (collectively, the "Seller Indemnitees") for, from and
against, and to pay or reimburse the Seller Indemnitees for, any and all Losses,
whether or not involving a Third Party Claim against any Seller Indemnitee,
resulting from or arising out of:

                  (a)      any breach or inaccuracy of any representation or
         warranty made by Purchaser in this Agreement or any other agreement and
         instrument to be executed and delivered by it pursuant hereto;

                  (b)      any breach by Purchaser of any of its covenants or
         obligations hereunder or under any other agreement and instrument to be
         executed and delivered by it pursuant hereto;

                  (c)      the conduct by Purchaser, directly or indirectly,
         (including through the Company or the Subsidiary) of the businesses of
         the Company and the Subsidiary following the Closing; and/or

                  (d)      any Reserve Excess pursuant to Section 9.7.

In no event shall the Seller Parties seek to enforce the foregoing indemnities
(or any other provision of this Agreement) with respect to Losses suffered by
their Affiliates pursuant to the


                                       57



performance by the Company and the Subsidiary of contracts between the Company
and/or the Subsidiary and the Seller Parties' Affiliates, including APS. All
such Losses shall be addressed under the terms of such contracts or Applicable
Law.

         9.4     Limitations on Indemnification Claims. Neither the Seller
Parties nor Purchaser will have any Liability pursuant to Section 6.5(a),
Section 9.2 or Section 9.3, as applicable, unless the aggregate amount of Losses
otherwise subject to its, or, in the case of the Seller Parties, taken together,
their, indemnification obligations thereunder exceeds Two Hundred Thousand
Dollars ($200,000) (the "Claim Threshold"), whereupon such Party shall be liable
for all Losses exceeding the Claim Threshold, subject to the further limitations
of this Agreement; provided, however, that in determining the Liability for any
breach of representation, warranty, covenant or agreement under this Agreement,
all references to a materiality or similar qualifier or Material Adverse Effect
shall be disregarded; and provided further that the Claim Threshold shall not
apply with respect to any breach by the Seller Parties of their representations
and warranties in Section 3.4, Section 4.4 or Section 4.5, Section 4.6(c) or
their covenants in Section 2.7 or Section 6.10(a), with respect to any breach by
Purchaser of its representations and warranties in Section 5.8 or its covenants
in Section 2.7, Section 6.10(b) or Section 6.13, or with respect to any
Liability arising pursuant to Section 9.2(c). Notwithstanding the foregoing or
any other provision of this Agreement other than the Tax Provisions:

                  (a)      the Seller Parties will not have any indemnification
         liability under this Agreement in respect of any Loss to the extent
         that such Loss is covered by insurance held by Purchaser or any
         Affiliate thereof (which, following the Closing, will include the
         Company and the Subsidiary and their respective successors), and
         Purchaser will not have any indemnification liability under this
         Agreement in respect of any Loss to the extent that such Loss is
         covered by insurance held by the Seller Parties or any Affiliate
         thereof (which, following the Closing, will exclude the Company and the
         Subsidiary and their respective successors); provided, however, that
         (i) to the extent the insurance company denies coverage, such Loss
         shall not be deemed to be "covered" by insurance and (ii) a Loss shall
         not be deemed to be "covered" by insurance to the extent of any
         applicable deductible or self-insurance retention;

                  (b)      a Purchaser Indemnitee or Seller Indemnitee (as the
         case may be) will be required to undertake reasonable efforts to
         mitigate any Loss in respect of which a claim for indemnification is
         made or in respect of which the amount of such Loss is added (or
         permitted to be added) to the Claim Threshold; provided, however, that
         a Purchaser Indemnitee or Seller Indemnitee (as the case may be) shall
         not be required pursuant hereto to incur any material costs or
         prosecute or defend any Proceeding;

                  (c)      the aggregate Liability of the Seller Parties for all
         Losses claimed by Purchaser Indemnitees under Section 6.5(a), Section
         9.2(a), Section 9.2(b) (other than for breach of the Seller Parties'
         obligations under Section 6.10(a)) or Section 9.2(d) will not exceed an
         amount equal to thirty-five percent (35%) of the Purchase Price;
         provided, however, that the aggregate liability of the Seller Parties
         for all Losses claimed by Purchaser Indemnitees as a result of any
         violation of Section 3.2, Section 4.4, or Section 4.5 will not exceed
         an amount equal to the Purchase Price; and


                                       58


                  (d)      the aggregate liability of Purchaser for all Losses
         claimed by Seller Indemnitees under Section 9.3(a), Section 9.3(b)
         (other than for breach of Purchaser's obligations under Section 6.10(b)
         or Section 6.13) or Section 9.3(d) will not exceed an amount equal to
         thirty-five percent (35%) of the Purchase Price; provided, however,
         that the aggregate liability of Purchaser for all Losses claimed by
         Seller Indemnitees as a result of any violation of Section 5.2 will not
         exceed an amount equal to the Purchase Price.

         9.5      Timing of Indemnification Claims. No Purchaser Indemnitee will
be entitled to recover under an indemnification claim against the Seller Parties
under Section 6.5(a) or Section 9.2, and no Seller Indemnitee will be entitled
to recover under an indemnification claim against Purchaser under Section 9.3,
unless such claiming Person has delivered to the applicable indemnifying Party
written notice of such claim for indemnification within the following applicable
claims period (each, a "Claims Period"):

                  (a)      with respect to any indemnification claim arising out
         of (i) the breach by any Party of any representation, warranty,
         covenant or agreement relating to such Party's authority and/or ability
         to enter into this Agreement and each other agreement and instrument to
         be executed and delivered by it pursuant hereto and consummate the
         transactions contemplated hereby or thereby, (ii) the breach by the
         Seller Parties of any representation, warranty or covenant regarding El
         Dorado's title to the Company Shares or the Company's title to the
         Subsidiary Shares, and their ability to transfer the same to Purchaser,
         free and clear of all Liens, (iii) any fraudulent act or willful
         misrepresentation by any Party with respect to this Agreement and/or
         the transactions contemplated hereby, and (iv) the conduct by Purchaser
         (directly or indirectly) of the businesses of the Company and the
         Subsidiary following the Closing, the Claims Period will commence on
         the date of the Closing and continue until thirty (30) days after
         expiration of the limitation period applicable thereto under the
         applicable statute of limitations;

                  (b)      with respect to any indemnification claim arising out
         of the breach by the Seller Parties of any of their covenants in
         Section 6.8 and Section 6.12, the Claims Period will commence on the
         date of the Closing and continue until thirty (30) days after the
         expiration of the period specified in such provision;

                  (c)      with respect to any indemnification claim arising out
         of the breach by the Seller Parties or Purchaser of any other
         representation, warranty, covenant or agreement in this Agreement or in
         any agreement, instrument or other document executed and delivered
         pursuant hereto, the Claims Period will commence on the date of the
         Closing and continue until the second (2nd) anniversary of the Closing
         Date; provided, however, that, with respect to any indemnification
         claim arising out of the breach by the Seller Parties of any of their
         representations and warranties in Section 4.12(c), the Claims Period
         will commence on the date of the Closing and continue until the third
         (3rd) anniversary of the Closing Date.

Notwithstanding the foregoing, if prior to 5:00 p.m. (New York time) on the last
day of the applicable Claims Period, the Party against which an indemnification
claim has been made hereunder has been properly notified in writing of such
claim for indemnity hereunder and such


                                       59



claim has not been finally resolved or disposed of as of such date, then such
claim will continue to survive and will remain a basis for indemnity hereunder
until such claim is finally resolved or disposed of in accordance with the terms
of this Agreement.

         9.6      Third-Party Claim Procedures.

                  (a)      Promptly after receipt by a Seller Indemnitee or a
         Purchaser Indemnitee, as the case may be (an "Indemnitee") of notice of
         the assertion of a Third-Party Claim against it, such Indemnitee will
         give prompt notice to the Party obligated to indemnify such Indemnitee
         under Section 9.2 or Section 9.3 as the case may be (each, an
         "Indemnitor") of the assertion of such Third-Party Claim, provided,
         however, that the failure to so notify the Indemnitor will not relieve
         the Indemnitor of any liability that it may have to such Indemnitee,
         except to the extent that the Indemnitor demonstrates that the defense
         of such Third-Party Claim was materially prejudiced by the Indemnitee's
         failure to give such prompt notice.

                  (b)      If an Indemnitee gives notice to an Indemnitor
         pursuant to Section 9.6(a) of the assertion of a Third-Party Claim, the
         Indemnitor will be entitled to participate in the defense of such
         Third-Party Claim (at its sole cost) and, subject to Section 9.6(c), to
         assume control of the defense of such Third-Party Claim with counsel
         reasonably satisfactory to the Indemnitee. After notice from the
         Indemnitor to the Indemnitee of its election to assume the defense of
         such Third-Party Claim, the Indemnitor will not, so long as it
         diligently conducts such defense, be liable to the Indemnitee under
         Section 9.2 or 9.3 (as applicable) for any fees of other counsel or any
         other expenses with respect to the defense of such Third-Party Claim,
         in each case subsequently incurred by the Indemnitee in connection with
         the defense of such Third-Party Claim, other than reasonable costs of
         investigation. If the Indemnitor assumes the defense of a Third-Party
         Claim, (i) such assumption will conclusively establish for purposes of
         this Agreement that the claims made in that Third-Party Claim are
         within the scope of, and subject to, indemnification as provided
         herein, and (ii) no compromise or settlement of such Third-Party Claims
         may be effected by the Indemnitor or will be binding on the Indemnitee
         without the Indemnitee's prior written consent (not to be unreasonably
         withheld or delayed), unless (A) there is no finding or admission of
         any violation of law or of the rights of any Person, (B) an
         unconditional term thereof is the release from all Liability with
         respect to such claim to each Indemnitee that is the subject of such
         Third-Party Claim, except as provided in clause (C), and (C) the sole
         relief provided is monetary damages that are paid in full by the
         Indemnitor. If notice is given by an Indemnitee to an Indemnitor of the
         assertion of any Third-Party Claim and the Indemnitor does not, within
         ten (10) Business Days after the Indemnitee's notice is given, give
         notice to the Indemnitee of its election to assume the defense of such
         Third-Party Claim, the Indemnitee will be entitled, to the Indemnitor's
         exclusion and at the Indemnitor's cost, to fully assume the defense of
         such Third-Party Claim, and the Indemnitor will be bound by any
         determination made in such Third-Party Claim or any compromise or
         settlement effected by the Indemnitee in respect thereof.

                  (c)      Notwithstanding the foregoing provisions of this
         Section 9.6, the Indemnitee may require that the Indemnitor not assume
         or maintain control of, or actively


                                       60



         participate in (in which case, the Indemnitor will not assume, maintain
         control of or actively participate in) the defense of, a Third Party
         Claim against the Indemnitee if (i) the Indemnitor is also a Person
         against whom the Third-Party Claim is made and the Indemnitee
         determines in good faith that joint representation of the Indemnitor
         and Indemnitee would be inappropriate, (ii) the Indemnitee requests,
         and the Indemnitor fails to provide, reasonable assurance to the
         Indemnitee of the Indemnitor's financial capacity to defend such
         Third-Party Claim and to provide indemnification with respect thereto,
         or (iii) the Indemnitee determines in good faith that there is a
         reasonable probability that the Third-Party Claim may adversely affect
         it or its Affiliates other than as a result of monetary damages for
         which it would be entitled to indemnification under this Agreement. In
         any of these events, the Indemnitee may, by written notice to the
         Indemnitor, assume the exclusive right to defend, compromise or settle
         such Third-Party Claim, but the Indemnitor will not be bound by any
         compromise or settlement of such Third-Party Claim for the purposes of
         this Agreement without its prior written consent to such compromise or
         settlement.

                  (d)      Each of the Seller Parties and Purchaser hereby
         consents, to the extent that it is an Indemnitor in respect of a
         Third-Party Claim, to the nonexclusive jurisdiction of any court or
         arbitration panel in which a Proceeding in respect of such Third-Party
         Claim is brought against any Indemnitee for purposes of any claim that
         an Indemnitee may have under this Agreement with respect to such
         Proceeding or the matters alleged therein, and agrees that process may
         be served on any Indemnitor with respect to such a claim anywhere in
         the world.

                  (e)      With respect to any Third-Party Claim subject to
         indemnification under Section 9.2 or Section 9.3, (i) the Indemnitee(s)
         and the Indemnitor(s), as the case may be, will keep the other(s) fully
         informed of the status of such Third-Party Claim and any related
         actions or proceedings at all stages thereof, and (ii) the Parties
         agree (each at its own expense) to render to each other such assistance
         as they may reasonably require of each other and to cooperate in good
         faith with each other in order to ensure the proper and adequate
         defense of any Third-Party Claim.

                  (f)      With respect to any Third-Party Claim subject to
         indemnification under Section 9.2 or Section 9.3, the Parties agree to
         cooperate in such a manner as to preserve to the greatest extent
         possible the confidentiality of all confidential and proprietary
         information of the Parties and the attorney-client and work-product
         privileges as between the Parties and their respective legal advisors.
         In connection therewith, each Party agrees that (i) it will use all
         reasonable efforts in respect of any Third-Party Claim in which it
         assumes or participates in the defense to avoid production of
         confidential and proprietary information (consistent with Applicable
         Law and rules of procedure), and (ii) all communications between each
         Party and counsel responsible for or participating in the defense of
         any Third-Party Claim will, to the greatest extent possible, be made so
         as to preserve any applicable attorney-client or work-product
         privilege.

                  (g)      With respect to any Third-Party Claim subject to
         indemnification under Section 9.2(c), reasonable expenses (including
         attorneys' fees) incurred by the Indemnitee


                                       61



         in connection therewith shall be paid by the Indemnitor as they are
         incurred in advance of the final disposition of such Third-Party Claim.

         9.7      Reserve Indemnity. If, within three (3) years of the Closing
Date, pursuant to any audit or review by any Governmental Authority in
connection with the Government Contracts set forth on Schedule 4.12(c), the
Company or the Subsidiary shall be required to make any payment or payments for
possible overcharges or potentially disputed or unallowable costs with respect
to work performed or costs incurred under such Government Contracts as of the
Closing Date in excess of the Reserve Amount plus any additional amounts
reserved between the date hereof and the Closing Date in respect thereof (the
"Additional Reserves"), then the Seller Parties shall indemnify Purchaser for
such excess amount (the "Reserve Shortfall"), subject to Section 9.4(c) and the
Claim Threshold. If, however, after such three-year period has expired, amounts
so payable by the Company or the Subsidiary, if any, are less than the Reserve
Amount plus the Additional Reserves, then Purchaser shall remit to the Seller
Parties for the difference between the amounts actually paid and the Reserve
Amount plus the Additional Reserves (the "Reserve Excess"), subject to Section
9.4(d) and the Claim Threshold. The Claims Period for claims pursuant to this
Section 9.7 will commence on the date of the Closing and continue until thirty
(30) days after the third anniversary of the Closing Date. Purchaser shall use
its commercially reasonable efforts to defend the position of the Company or the
Subsidiary, as the case may be, in connection with any such audit or review by a
Governmental Authority and, upon the written request of either of the Seller
Parties, will promptly provide the Seller Parties with reasonable information
regarding the scope or status of any such audit or review.

         9.8      Exclusive Remedy. Except to the extent provided in Section
10.2, from and after the Closing, the indemnification obligations and remedies
set forth in this Article 9 will be the sole and exclusive remedy of the Seller
Parties and Purchaser with respect to the matters for which indemnification may
be sought pursuant to this Article 9, except in the event of fraud. Without
limiting the generality of the foregoing, no Proceeding based upon predecessor
or successor liability, contribution, tort or strict liability, in each case
except to the extent such claim is based on fraud, may be maintained by the
Seller Parties or Purchaser against the other with respect to the matters for
which indemnification is provided pursuant to this Article 9. Notwithstanding
anything to the contrary contained in this Article 9, the representations,
warranties, covenants, agreements, obligations, indemnities, and time limits
pertaining to matters addressed in the Tax Provisions shall be governed solely
as provided therein.

                                   ARTICLE 10
                                  MISCELLANEOUS

         10.1      Expenses. Except as otherwise expressly provided in this
Agreement, the Seller Parties and Purchaser will bear their respective expenses,
costs and fees (including attorneys' and other advisors' fees) in connection
with the transactions contemplated hereby, including the preparation, execution,
and delivery of this Agreement and the other agreements and instruments to be
entered into pursuant hereto and the preparation and filing of any notices or
applications with respect to required Consents, whether or not the transactions
contemplated hereby are consummated.


                                       62


         10.2      Specific Performance. The Parties hereby acknowledge and
agree that the rights of each Party to consummate the transactions contemplated
hereby are special, unique and of extraordinary character, and that if any Party
refuses or otherwise fails to consummate the sale and purchase of the Company
Shares as contemplated herein (other than as permitted by the provisions
hereof), such refusal or failure would result in irreparable injury to the other
Party, the exact amount of which would be difficult to ascertain or estimate and
the remedies at law for which would not be reasonable or adequate compensation.
Accordingly, if any Party refuses or otherwise fails to consummate the sale and
purchase of the Company Shares as contemplated herein (other than as permitted
by the provisions hereof), then, in addition to any other remedy which may be
available to the other Party at law or in equity, such other Party will be
entitled to seek specific performance and injunctive relief, without posting
bond or other security, and without the necessity of proving actual or
threatened damages, which remedy such Party will be entitled to seek in any
court of competent jurisdiction.

         10.3      Severability. If any provision of this Agreement, or the
application of any such provision to any Person or circumstance, is held to be
unenforceable or invalid by any Governmental Authority or arbitrator or under
any Applicable Law, the Parties will negotiate an equitable adjustment to the
provisions of this Agreement with the view to effecting, to the greatest extent
possible, the original purpose and intent of this Agreement, and in any event,
the validity and enforceability of the remaining provisions of this Agreement
will not be affected thereby.

         10.4      Notices. All notices, requests, demands, claims and other
communications required or permitted to be given or made hereunder must be in
writing. Any notice, request, demand, claim, or other communication hereunder
will be deemed duly given and received (i) if personally delivered, when so
delivered, (ii) if mailed, five (5) Business Days after having been sent by
registered or certified mail, return receipt requested, postage prepaid and
addressed to the intended recipient as set forth below, (iii) if sent through an
overnight delivery service in circumstances to which such service guarantees
next day delivery, the next Business Day following being so sent, and (iv) if
sent by electronic facsimile, once such notice or other communication is
transmitted to the fax number specified below and the appropriate printed
confirmation of transmission is received, provided that such notice or other
communication is promptly thereafter mailed in accordance with the provisions of
clause (ii) above or sent by overnight delivery service in accordance with
clause (iii) above:

Any Party may give any notice, request, demand, claim or other communication
hereunder using any other means (including electronic mail), but no such notice,
request, demand, claim or other communication will be deemed to have been duly
given or received unless and until it actually is received by the Party for
which it is intended and the notifying Party can provide evidence of such actual
receipt. Any Party may change its address or fax number for the receipt of
notices, requests, demands, claims and other communications hereunder by giving
each other Party notice of such change in the manner herein set forth.

         10.5     Dispute Resolution. Subject to the provisions of Section 10.2,
any dispute or difference between the Parties arising out of or in connection
with this Agreement or the transactions contemplated hereby, including any
dispute between an Indemnitee and any Indemnitor under Article 9, which the
Parties are unable to resolve themselves will be submitted to and resolved by
arbitration before a single arbitrator, for amounts in dispute under One Million
Dollars ($1,000,000), and otherwise before a panel of three (3) arbitrators,
pursuant to the Commercial Arbitration Rules of the American Arbitration
Association, as supplemented or modified by the provisions of this Section 10.5.
The arbitrator(s) will consider the dispute at issue in New York, New York
within one hundred twenty (120) days (or such other period as may be acceptable
to the Parties) of the designation of the arbitrator. The arbitrator(s) will be
bound to follow the laws of the State of Delaware, decisional and statutory, in
reaching any decision and making any award and will deliver a written award,
including written findings of fact and conclusions of law, with respect to the
dispute to each of the Parties, who will promptly

                                       64



act in accordance therewith. In no event will the arbitrator(s) have the power
to award damages in connection with any dispute in excess of actual compensatory
damages. In particular, the arbitrator(s) may not multiply actual damages or
award consequential, indirect, special or punitive damages, including damages
for lost profits or loss of business opportunity. Any award of the arbitrator(s)
will be final, conclusive and binding on the Parties; provided, however, that
any Party may seek the vacating, modification or correction of the
arbitrator(s)' decision or award as provided under Section 10 and Section 11 of
the Federal Arbitration Act 9 U.S.C. Section 1-14. Any determination made or
award rendered pursuant to the arbitration provisions of this Section 10.5 shall
be subject to Section 6.3(a) hereof. Notwithstanding the foregoing sentence, any
Party may enforce any award rendered pursuant to the arbitration provisions of
this Section 10.5 by bringing suit in any court of competent jurisdiction. All
costs and expenses attributable to the arbitrator(s) will be allocated between
the Parties in such manner as the arbitrator(s) determine to be appropriate
under the circumstances. The Parties agree that either or both of them may file
a copy of this Section 10.5 with any arbitrator or court as written evidence of
the knowing, voluntary and bargained agreement between the Parties with respect
to the subject matter of this Section 10.5. Notwithstanding anything to the
contrary contained in this Section 10.5, any dispute or difference between the
Parties relating to Taxes, or the interpretation or application of any of the
Tax Provisions, shall be resolved solely as set forth in the Tax Provisions.

         10.6     Headings; Interpretation. The headings contained in this
Agreement are for purposes of convenience only and will not affect the meaning
or interpretation of this Agreement. Unless otherwise expressly indicated, any
reference in this Agreement (including any Schedule hereto) to an "Article,"
"Section," "subsection," "paragraph" or "subparagraph" followed by a number or
letter or combination of the two will be a reference to the particular Article,
Section, subsection, paragraph or subparagraph of this Agreement bearing such
number, letter or combination thereof. The terms "hereof," "herein," "hereunder"
and comparable terms refer, unless otherwise expressly indicated, to this
Agreement as a whole and not to any particular Article, Section, subsection,
paragraph, subparagraph or other subdivision hereof or any Schedule, Exhibit or
other attachment hereto. The terms "include," "includes" and "including" will be
deemed to be followed by the words "without limitation." Whenever the context so
requires, the singular number will include the plural and the plural will
include the singular, and the gender of any pronoun will include the other
gender or neuter, as applicable. Any reference in this Agreement to a particular
statute, regulation or code (including any specific provision thereof) includes
all regulations and rules thereunder, all amendments thereto in force from time
to time (including amendments to provision references) and every Applicable Law
in effect that supplements, replaces or supercedes such statute, regulation or
code. Whenever consent or approval of any Party is required pursuant to this
Agreement, unless expressly stated that such consent or approval is to be given
in the sole discretion of such Party, such consent or approval shall not be
unreasonably withheld or delayed. Unless otherwise expressly indicated, the
phrase "the transactions contemplated hereby" will be deemed to include the sale
of the Company Shares to Purchaser and the Preliminary Merger, each in
accordance with the provisions of this Agreement.

         10.7     Entire Agreement. This Agreement (including the Schedules and
Exhibits hereto) constitutes the entire and complete agreement between the
Parties with respect to the subject matter hereof and supersedes and replaces
all prior agreements, commitments, communications,


                                       65


representations and understandings, both written and oral, between the Parties
with respect to the subject matter hereof (including any letter of intent
between the Seller Parties and Purchaser or any of their respective Affiliates).

         10.8     Governing Law, etc. This Agreement will be governed in all
respects, including as to validity, interpretation and effect, by the internal
laws of the State of Delaware, without giving effect to the conflict of laws
rules thereof.

         10.9     Binding Effect; Assignment. This Agreement will be binding
upon and inure to the benefit of the Parties and their respective successors and
permitted assigns. No Party may assign its rights or delegate or cause to be
assumed its obligations hereunder without the prior written consent of the other
Parties; provided, however, that Purchaser may assign its right to purchase the
Company Shares to any Affiliate of Purchaser as long as such Affiliate agrees in
writing to be bound by the applicable terms of this Agreement and no such
assignment shall relieve Purchaser from its obligations hereunder and El Dorado
may assign its rights to receive the Purchase Price to Parent and no such
assignment shall relieve El Dorado from its obligations hereunder. Any attempted
assignment, delegation or assumption not in accordance with this Section 10.9
will be null and void and of no effect whatsoever.

         10.10    No Third Party Beneficiaries. Except as provided in Article 9
with respect to indemnification of Indemnitees hereunder, nothing in this
Agreement will confer any rights upon any Person other than the Parties and
their respective successors and permitted assigns.

         10.11    Amendment; Waivers, etc. No amendment, modification, or
discharge of this Agreement, and no waiver hereunder, will be valid or binding
unless set forth in writing and duly executed by the Party against whom
enforcement of the amendment, modification, discharge, or waiver is sought. Any
such waiver will constitute a waiver only with respect to the specific matter
described in such writing and will in no way impair the rights of the Party
granting such waiver in any other respect or at any other time. Neither the
waiver by any Party of a breach of or a default under any provision of this
Agreement, nor the failure by any Party, on one or more occasions, to enforce
any provision of this Agreement or to exercise any right or privilege hereunder,
will be construed as a waiver of any other breach or default of a similar
nature, or as a waiver of any of such provisions, rights, or privileges
hereunder. The rights and remedies herein provided are cumulative and are not
exclusive of any rights or remedies that any Party may otherwise have at law or
in equity. The rights and remedies of any Party based upon, arising out of or
otherwise in respect of any inaccuracy or breach of any representation,
warranty, covenant, or agreement, or failure to fulfill any condition will in no
way be limited by the fact that the act, omission, occurrence, or other state of
facts upon which any claim of any such inaccuracy or breach is based may also be
the subject matter of any other representation, warranty, covenant, or agreement
as to which there is no inaccuracy or breach. The representations and warranties
of the Seller Parties will not be affected or deemed waived by reason of any
investigation made by or on behalf of Purchaser (including by any of its
advisors, consultants or representatives) or by reason of the fact that
Purchaser or any of such advisors, consultants or representatives knew or should
have known that any such representation or warranty is or might be inaccurate.

         10.12    Dates and Times. Dates and times set forth in this Agreement
for the performance of the Parties' respective obligations will be strictly
construed, time being of the


                                       66


essence of this Agreement. All provisions in this Agreement which specify or
provide a method to compute a number of days for the performance, delivery,
completion or observance by a Party of any action, covenant, agreement,
obligation or notice hereunder will mean and refer to calendar days, unless
otherwise expressly provided. If the date specified or computed under this
Agreement for the performance, delivery, completion or observance of a covenant,
agreement, obligation or notice by any Party, or for the occurrence of any event
provided for herein, is a day other than a Business Day, then the date for such
performance, delivery, completion, observance or occurrence will automatically
be extended to the next Business Day following such date.

         10.13    Joint Preparation. This Agreement and each agreement or
instrument entered into by the Parties pursuant to the provisions hereof will be
considered for all purposes as having been prepared through the joint efforts of
the Parties. No presumption will apply in favor of any Party in the
interpretation of this Agreement or any such other agreement or instrument or in
the resolution of any ambiguity of any provision hereof or thereof based on the
preparation, substitution, submission or other event of negotiation, drafting or
execution hereof or thereof.

         10.14    Limitation of Liability. NOTWITHSTANDING ANY OTHER PROVISION
OF THIS AGREEMENT, IN NO EVENT WILL ANY PARTY BE LIABLE FOR ANY INDIRECT,
INCIDENTAL, SPECIAL, CONSEQUENTIAL OR PUNITIVE DAMAGES, INCLUDING DAMAGES FOR
LOSS OF PROFITS OR BUSINESS OPPORTUNITY, INCURRED BY ANY OTHER PERSON, WHETHER
IN CONTRACT OR TORT OR BASED ON A WARRANTY, EVEN IF THE PARTY WHO IS THE SUBJECT
OF SUCH CLAIM HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

         10.15    Counterparts. This Agreement may be executed in several
counterparts and delivered in original form or by electronic facsimile, each of
which will be deemed an original and all of which will together constitute one
and the same instrument.
