agreements previously entered into between your company and Lucent for products
and services from the Enterprise Networks Group are assigned from Lucent to
Avaya, effective immediately prior to the spin-off on October 1, 2000.

Though our name has changed, we continue to be committed to serving our global
markets and to providing the same quality products and customer service with the
same professionalism and integrity you have come to know and expect.

as we move forward as an exciting, fully independent business.

                  based upon Seller's earnings before interest, taxes,
                  depreciation and amortization ("EBITDA") for FY2001, such that
                  Seller will be paid $3.90625 for each dollar of EBITDA
                  produced by the Purchased Business during FY2001 in excess of
                  $442,000 (adjusted to reflect a change from cash to accrual
                  basis accounting), payable on or before February 1, 2002. For
                  purposes of this provision, EBITDA will be calculated
                  consistent with Seller's past policies and practices, adjusted
                  to reflect a change from cash to accrual basis accounting, but

<PAGE>   8

Closing, and Purchaser shall have thirty (30) days following such delivery
("EQUITY DETERMINATION PERIOD") to review the Closing Balance Sheet to complete
Purchaser's verification that Seller's receivables are collectible and that
there have been no material changes in the assets or liabilities of Seller since
August 31, 2000 (other than the Permitted Distributions). At the end of the
Equity Determination Period, Purchaser shall deliver to the Seller a certificate
("CLOSING EQUITY CERTIFICATE") signed by an officer of Purchaser indicating its
determination of the amount of Seller's total stockholder's equity of the
Closing Date ("CLOSING EQUITY VALUE") as determined by Purchaser in good faith,
and, subject to Section 2.4 below, Purchaser shall pay the Seller an amount
equal to the excess of Seller's Closing Equity Value over the amount paid to the
Seller pursuant to Section 2.2(b); provided that if Seller's Closing Equity
Value is less than $100,000, Seller shall reimburse Purchaser to the extent of
such deficit. Seller's books shall be closed as of the Closing Date consistent
with past practice in accordance with GAAP.

Section 2.3 above, Seller and its representatives shall have the right for a
period of thirty (30) days after receiving the Closing Equity Certificate to
review its books and records as of the Closing Date and, if Seller desires, to
have an independent public accountant examine such book and records, for up to
an additional sixty (60) days (ninety (90) days in all), to verify Purchaser's
calculation of the Closing Equity Value. If Seller does not agree with
Purchaser's calculation of Closing Equity Value, the parties shall negotiate in
good faith to agree upon such value and allocation, and to the extent that the
Closing Equity Value is found to have been less than $100,000, Seller shall
reimburse Purchaser the amount of such deficiency with in ten (10) days after
delivery of such independent evaluation. If the independent evaluation
established a Closing Equity Value which is 110% or more of the value determined
by Purchaser as set forth in the Closing Equity Certificate, Purchaser shall pay
all costs incurred by Seller in connection with such independent evaluation.

         2.5 Assumed Liabilities. As further consideration for Asset Purchase,
Purchaser shall assume and discharge all liabilities and obligations of Seller
properly shown and adequately reserved for in the Financial Statements except
those liabilities listed in Schedule 2.5 ("EXCLUDED LIABILITIES").

allocate the Purchase Price among the Assets in accordance with the book value
of Seller's assets as reflected in the Closing Date Balance Sheet. The parties
agree to file any and all applicable tax returns and other required related tax
schedules in accordance with such allocation and Section 1060 of the Internal
Revenue Code and will not adopt or otherwise assert tax positions inconsistent
therewith. Purchaser and Seller shall each prepare and file its Form 8594 for

Agreement.

contract or right to be assigned or transferred to Purchaser as provided in this
Agreement shall require the consent of the other party thereto, this Agreement
shall not constitute an agreement to assign or transfer the same if any
attempted assignment would constitute a breach thereof. Seller agrees that it
will use its best efforts to obtain the consent of the other parties to all
Material Contracts to the assignment or transfer thereof to Purchaser. Seller
shall have no liability to Purchaser for failure to obtain any such third party
consent provided Seller complies with its obligations under this section.
Purchaser agrees that it will cooperate with and assist Seller in its efforts to
obtain any such consents. If Seller is unable to obtain any necessary consent to
an assignment or transfer to Purchaser of any Material Contract, Purchaser shall
have the right to terminate this Agreement pursuant to Section 11.1 without
liability to any party under this Agreement.

assessments which are levied or assessed based solely on time periods (e.g.,
property taxes but not sales or income taxes), relating to the Assets for the
periods during which the Closing occurs ("PRORATED TAXES"), shall not be deemed
to be part of the Assumed Liabilities or Assets to be acquired by Purchaser, but
shall be prorated between Seller and Purchaser, as of the Closing Date, with
Purchaser bearing only that portion of such expense that the number of days
after the Closing Date bears to the total number of days in the applicable
period and Seller bearing only that portion of such expense that the number of
days prior to the Closing Date bears to the total number of days in

                                       9

the applicable period. To the extent not adjusted in cash at Closing, all
requests for payment of taxes properly attributable to one party that are
received by the other will be promptly forwarded to the other party, which shall

interfere with such employees' performance of their duties for Purchaser nor
materially interfere with or materially adversely affect Purchaser's
relationships with its customers, suppliers, licensors, licensees, consultants
or employees.

                  5.19.4 Compliance. To the knowledge of Seller and the
         Principal Shareholder, (a) the Pension Plan and each of the Welfare
         Plans complies currently, and has complied in the past, both as to form
         and operation and in all material respects, with its own terms and with
         the provisions of ERISA and the Code, and all other applicable laws,
         rules and regulations; (b) all necessary governmental approvals and
         determinations for the Pension Plan have been obtained, including where
         applicable, a favorable determination as to its qualification under
         Sections 401(a), and 501(a) of the Code; and (c) nothing has occurred
         since the date of each such determination or recognition letter that
         would adversely affect such qualification. To the knowledge of the
         Seller and the Seller, all amounts that are currently owing to plan
         participants, or contributions required to be made to the Pension Plan
         or any of the Welfare Plans have been paid or contributed with respect
         to all periods prior to the Closing Date or have been provided for by
         adequate reserves in the Financial Statements.

                  5.19.5 COBRA. To the knowledge of Seller and the Principal
         Shareholder, except as set forth in Schedule 5.19.5, Seller has
         complied in all material respects with the "CONTINUATION COVERAGE
         REQUIREMENTS OF GROUP HEALTH PLANS" provided in Section 4980B of the
         Code, Sections 601 et. seq. of ERISA, the Family and Medical Leave Act
         of 1994, and all regulations promulgated thereunder.

                  5.19.6 401(k) Plan. The Seller's 401(k) Plan permits, or prior
         to Closing shall be amended to permit, employees of Seller who are
         hired by Purchaser to roll or directly transfer their vested account
         balances to a "QUALIFIED EMPLOYEE PENSION PLAN" at no cost to
         Purchaser.

                  5.19.7 Miscellaneous Benefit Plan Matters. Neither Seller nor
         any other entity, whether or not incorporated, which is deemed to be
         under "COMMON CONTROL" (as defined in Section 414 of the Code, or
         4001(b) of ERISA) with Seller ("COMMONLY CONTROLLED ENTITY") maintains
         or contributes to any "EMPLOYEE PENSION BENEFIT PLAN" (within the
         meaning of Section 3(2)(A) of ERISA) that (a) is a "DEFINED
         CONTRIBUTION PLAN" described in Section 3(34) of ERISA or Section
         414(i) of the Code, or a "DEFINED BENEFIT PLAN" described in Section
         3(35) of ERISA or Section 414(j) of the Code, and (b) gives rise, or
         will give rise, to any liability of Seller for (i) any delinquent
         premium payments due under Section 4007 or ERISA with respect to any
         such defined benefit plan, or (ii) any unpaid minimum funding
         contributions that would result in the imposition of a lien on any
         assets of Seller pursuant to Section 412(c)(11) of the Code or Section
         302(c)(11) of ERISA. Neither Seller nor any "COMMONLY CONTROLLED
         ENTITY" (as defined in ERISA) sponsors or sponsored, maintains or
         maintained, any defined benefit plan that has been, or will be,
         terminated in a manner that would result in any liability of Seller to
         the Pension Benefit Guaranty Corporation or that would result in the
         imposition of a lien on any assets of Seller pursuant to Section 4068
         of ERISA. At no time during the five-year period immediately preceding
         the first day of the year in which the Closing Date occurs has Seller
         or any Commonly Controlled Entity participated in or contributed to any
         "MULTI-EMPLOYER PLAN" (within the meaning of Section 4001(a)(3) of
         ERISA or Section 414(f) of the Code), or had an obligation to
         participate in or contribute to any such multi-employer plan. No
         agreement subject to Section 4204 of ERISA has been entered into in
         connection with the Asset

                                       16
<PAGE>   17

         Purchase. None of the Welfare Plans provides for or promises retiree
         medical, disability or life insurance benefits to any current or former
         employee, officer, or director of Seller.

         5.20 Litigation and Legal Compliance. Except as set forth in Schedule
5.20, there is no material claim, action, suit or proceeding, pending or, to the
knowledge of the Seller and the Principal Shareholder, threatened against or
affecting Seller, at law or in equity, or before or by any Governmental
Authority having jurisdiction over Seller. No written notice of any claim,
action, suit or proceeding, whether pending or threatened, has been received by
the Seller and, to the Principal Shareholder's and Seller's knowledge, there is
no basis therefor. Except to the extent set forth in Schedule 5.20, the Seller
has conducted and is conducting the Business in compliance with all Laws
applicable to Seller, the Assets or the operation of the Business.

         5.21 Taxes. Except as set forth in Schedule 5.21, Seller has timely
filed all requisite federal, state, local and other tax returns for all fiscal
periods for which the applicable statute of limitations has not expired, and has
duly paid in full or made adequate provision in the Financial Statements for the
payment of all Taxes for all periods for which the applicable statute of
limitations has not expired. Seller has duly withheld and paid or remitted all
Taxes required to have been withheld and paid in connection with amounts paid or
owing to any employee, independent contractor, creditor, shareholder or other
person or entity that required withholding under any applicable Law, including,
without limitation, any amounts required to be withheld or collected with
respect to social security, unemployment compensation, sales or use taxes or
workers' compensation. There are no examinations in progress or claims against
Seller relating to Taxes for any period or periods prior to and including the
Effective Date and no written notice of any claim for Taxes, whether pending or
threatened, has been received. Seller has not granted or been requested to grant
any extension of the limitation period applicable to any claim for Taxes or
assessments with respect to Taxes. Seller is not a party to any tax allocation
or sharing agreement and is not otherwise liable or obligated to indemnify any
person or entity with respect to any Taxes. The amounts shown as accruals for
Taxes in the Financial Statements as of August 31, 2000 are, and at Closing will
be, sufficient for the payment of all Taxes for all fiscal periods ended on or
before that date. Seller currently utilizes the accrual method of accounting for
income tax purposes. Such method of accounting has not changed in the past five
(5) years.

         5.22 Solvency. Seller is not insolvent, and will not be rendered
insolvent by the transfer contemplated by this Agreement. Seller assets exceed
its liabilities, and Seller is currently paying its obligations as they become
due.

         5.23 Change of Name. Except as set forth in Schedule 5.23, Seller has
not conducted business under any name during the past five (5) years other than
Key Metrology Integration, Inc. or KMI.

         5.24 Books and Records. The books of account, minute books, stock
record books, and other records of Seller, are complete and correct in all
material respects, have been maintained in accordance with sound business
practices, and all of them have been made available for inspection by Purchaser.

         5.25 Disclosure. Seller has fully provided Purchaser and its
representatives with all the information that Purchaser has requested in
analyzing whether to consummate the Asset Purchase. None of the information so
provided nor any representation or warranty of Seller contained in this
Agreement contains any untrue statement of a material fact, or omits to state a
material fact necessary to make such representation, warranty or statement, in
light of the circumstances under which they were made, not misleading.

         5.26 No Implied Representations. Notwithstanding anything to the
contrary contained in this Agreement, the Seller and the Principal Shareholder
have not made any representation or warranty whatsoever, express or implied,
other than those representations and warranties of the Seller and the Principal
Shareholder expressly set forth in this Agreement.

schedules and exhibits are free of any untrue statements of material fact and do
not omit to state a material fact necessary to make the statements contained in
this Agreement and the attached schedules and exhibits not misleading. To the

adversely affects the Business or the Assets.

or with sales representatives for marketing purposes, all tangible personal
property included in the Assets is currently found at the locations set forth in
Schedule 5.28.

                                    ARTICLE X
                                 INDEMNIFICATION

         10.1 Survival of Representations and Warranties. The parties hereto
agree that their respective representations, warranties, covenants, and
agreements contained herein shall survive the Closing for a period of two (2)
years after the Closing Date except that those covenants, representatives and
warranties made by Seller with respect to Environmental Matters, Employee
Benefits and Taxes (Sections 5.15, 5.19 and 5.21 hereof) shall survive the
Closing for such periods of time that the Governmental Authority having
jurisdiction over the subject matter of those covenants, representations and
warranties may be empowered to assess a liability or deficiency with respect to
any of the matters covered thereby (the "INDEMNIFICATION PERIOD").

         10.2 Indemnification by the Seller. Subject to the other provisions of
this Article X, the Seller and the Principal Shareholder agree to save and
indemnify Purchaser against, and hold it harmless from, any and all liabilities,
of every kind, nature and description, fixed or contingent, including without
limitation reasonable attorney fees and expenses incurred in connection with any
action, claim or proceeding relating to such liabilities ("DAMAGES"), arising
from the breach of any of his representations, warranties, covenants, or
agreements, contained herein or in the Exhibits or Schedules hereto, a claim for
which is asserted in writing by Purchaser during the Indemnification Period.

         10.3 Indemnification by Purchaser. Purchaser agrees to save and
indemnify the Seller against and to hold him harmless from any and all Damages
arising from the breach of any of Purchaser's representations, warranties,
covenants or agreements contained herein or the Exhibits hereto, a claim for
which is asserted in writing by Seller during the Indemnification Period.

         10.4 Claims. All claims for Damages shall be computed net of the
present value of all readily ascertainable future tax benefits associated
therewith. No claim shall be made for matters adequately covered by insurance,
nor may any party recover punitive damages as part of its Damages.

         10.5 Defense of Claims. Each party entitled to indemnification under
this Article X (the "INDEMNIFIED PARTY") agrees to notify the party required to
provide indemnification (the "INDEMNIFYING PARTY") with reasonable promptness of
any claim asserted against it in respect of which the Indemnifying Party may be
liable under this Agreement, which notification shall be accompanied by a
written statement setting forth the basis of such claim and the manner of
calculation thereof. The Indemnifying Party shall have the right, at its
election, to defend or compromise any such claim at its own expense with counsel
of its choice; provided, however, that (i) such counsel shall have been approved
by the Indemnified Party, which approval shall not be unreasonably withheld or
delayed; (ii) the Indemnified Party may participate in such defense if it so
chooses with its own counsel and at its own expense; and (iii) any such defense
or compromise shall be conducted in a manner which is reasonable and not
prejudicial to the Indemnified Party's interest in such matter. In the event the
Indemnifying Party does not undertake to defend or compromise the claim, the
Indemnifying Party shall promptly notify the Indemnified Party of its intention
not to undertake to defend or compromise the claim, and the

                                       25
<PAGE>   26

Indemnifying Party shall be bound by (a) the final decree of any court of
competent jurisdiction deciding the validity and amount of the claim asserted
against the Indemnified Party, and (b) any compromise of such claim made with
the prior consent of the Indemnifying Party, which shall not be unreasonably
withheld or delayed.

         10.6 Extension of Time. To the extent that an Indemnified Party
delivers written notice of a claim for Damages against an Indemnifying Party
prior to the expiration of the Indemnification Period, reasonably identifying
the basis for the claim and the amount of any reasonably ascertainable Damages,
the Indemnification Period shall be extended for such claim until such claim is
resolved by a Final Determination.

         10.7 Final Determination. For the purposes of this Agreement, a "FINAL
DETERMINATION" shall exist when (i) the parties agree in writing upon the
amount, or (ii) a court of competent jurisdiction shall have made a
determination on the merits with respect thereto and appeal therefrom shall not
have been taken within a timely fashion from the date of such determination. The
asserting party will assign to the other party any claims against which the
asserting party has been indemnified and paid as provided herein, as to which
there may be claims against persons other than the Seller, and the other party
in all respects shall be subrogated to the rights of the asserting party in
connection therewith.

         10.8 Limitations on Indemnification.

                  (a) Notwithstanding anything to the contrary herein, except as
         provided in this Section 10.8, (i) Seller and the Principal Shareholder
         shall not be liable under this Article X unless and until the aggregate
         Damages exceed $50,000 (at which point Seller and the Principal
         Shareholder shall only become liable for the aggregate Damages in
         excess of $50,000, and (ii) except for claims based on fraud or
         intentional misrepresentation, Seller's and the Principal Shareholder's
         aggregate liability under this Article X shall not exceed amounts
         payable by Purchaser to Seller under Section 2.2.

                  (b) Notwithstanding anything to the contrary herein, except as
         provided in this Section 10.8, (i) Purchaser shall not be liable under
         this Article X unless and until the aggregate Damages exceed $50,000
         (at which point Purchaser shall only become liable for the aggregate
         Damages in excess of $50,000), and (ii) except for claims based on
         fraud or intentional misrepresentation, Purchaser's aggregate liability
         under this Article X shall not exceed $500,000.

         10.9 Exclusivity. The remedies contained in this Article X, including
any remedy arising out of, relating to, in the nature of, or caused by the
violation or any breach of a representation, warranty or covenant contained in
this Agreement or with respect thereto, shall be exclusive of all other
statutory or common law remedies available to any party; provided, however, that
nothing set forth herein shall prohibit any party from seeking specific
performance or injunctive relief for any actual or threatened breach of this
Agreement.

                                   ARTICLE XI
                                   TERMINATION

         11.1 General. Anything herein or elsewhere to the contrary
notwithstanding, this Agreement may be terminated at any time prior to the
Closing Date:

                  (a) By mutual written consent of Seller and Purchaser;

                  (b) By Purchaser if, through no fault of Purchaser, any of the
         conditions set forth in Article VIII shall not have been fulfilled, or
         shall become incapable of fulfillment, on or prior to November 15,
         2000, and shall not have been waived;

                  (c) By Purchaser or Seller, if the Closing Date shall not have
         occurred on or prior to November 15, 2000 (or such later date as shall
         have been approved by the parties), unless such failure of such
         occurrence shall be due to the failure of the party seeking to
         terminate this Agreement to perform or observe the covenants,
         agreements and conditions hereof to be performed or observed by such
         party at or before the Closing Date;

                  (d) By Purchaser or Seller, if any court of competent
         jurisdiction or other governmental body shall have issued an order,
         decree or ruling or taken any other action restraining, enjoining or
         otherwise prohibiting the transactions contemplated by this Agreement
         and such order, decree, ruling or other action shall not have been
         withdrawn within thirty (30) days after the date on which such order,
         decree, ruling or other action was first issued or taken, or by reason
         of any litigation or proceeding pending or threatened to be instituted
         by any person or governmental body, which, in either case in the good
         faith judgment of its Board of Directors will in all likelihood result
         in an order, decree or ruling enjoining or otherwise prohibiting the
         transactions contemplated by this Agreement; or

                  (e) By Purchaser or Seller, if any representation or warranty
         given or made in this Agreement or any attachment by the other was
         untrue in any material respect as of the date given or made or as of
         the Closing Date, in light of the circumstances under which such
         representation or warranty was given or made, or if any covenant given
         or made in or pursuant to this Agreement, and performable by the other
         before and as a condition to the Closing is breached and such breach is
         not promptly cured after notice.

         11.2 Effect. In the event of termination or abandonment by reason of
Section 11.1, this Agreement shall forthwith become void and there shall be no
liability of one party to the other by reason of this Agreement unless the
reason for termination or abandonment was caused by the action, the failure to
act, the misrepresentation, omission or breach by the party to be charged with
such liability with respect to a material aspect of the contemplated
transaction.

         12.1 Entire Agreement. This Agreement (including the Schedules and
Exhibits hereto) and the documents delivered pursuant hereto constitute the
entire agreement and understanding among the Principal Shareholder, Seller and
Purchaser superseding any prior agreement and understanding relating to the

or such other address as any party hereto shall specify pursuant to this Section
12.4 from time to time.

         12.5 Rights and Remedies. Except as otherwise provided herein, no delay
of or omission in the exercise of any right, power or remedy accruing to any
party as a result of any breach or default by any other party under this
Agreement shall impair any such right, power or remedy, nor shall it be
construed as a waiver of or acquiescence in any such breach or default, or of
any similar breach or default occurring later; nor shall any waiver of any
single breach or default be deemed a waiver of any other breach or default
occurring before or after that waiver.

         12.6 Reformation and Severability. In case any provision of this
Agreement shall be invalid, illegal or unenforceable, it shall, to the extent
possible, be modified in such manner as to be valid, legal and enforceable, but
so as to most nearly retain the intent of the parties, and if such modification
is not possible, such provision shall be severed from this Agreement, and in
either case, the validity, legality and enforceability of the remaining
provisions of this Agreement shall not in any way be affected or impaired
thereby.

         12.7 Governing Law. This Agreement shall be construed in accordance
with the laws of the State of Oklahoma applicable to contracts to be entered
into and fully performed in the State of Oklahoma by residents of the State of
Oklahoma.

         12.8 Further Assurances. Each party will, upon request of the other
party, from time to time after the Closing, execute and deliver to the other all
such further documents and instruments,

                                       29
<PAGE>   30

and will do or use its reasonable best efforts to cause to be done such other
acts, as such other party may reasonably request more completely to consummate
and make effective the contemplated transactions.

         12.9 Expenses. Each party shall pay its own expenses in connection with
this Agreement and the transactions contemplated by this Agreement. Seller shall
indemnify Purchaser against any claims of third parties for brokerage
commissions or finders fees in connection with the transactions contemplated by
this Agreement insofar as such claims are alleged to be based on arrangements
made by Seller or any authorized agent thereof. Seller represents that the only
such arrangement made by Seller is with The Geneva Companies, Attention Mr. Ian
Joseph, as to whose fees Seller shall be solely responsible. Purchaser shall
indemnify Seller against any such claim of third parties for brokerage
commissions or finders' fees in connection with the transactions contemplated by
this Agreement insofar as they are alleged to be based on arrangements made by
Purchaser. Purchaser represents that no such arrangements exist. All sales, use
or other tax, duty or recording cost, if any, imposed upon the transfer of the
assets and business to be acquired by Purchaser pursuant to this Agreement shall
be paid by Seller.

         12.10 Confidential Information. Each party agrees it and its
representatives shall hold in strict confidence, and shall not use for its own
account or for the account of others, nor divulge or disclose to any person
without a need to know, any information and documents received from the other
party and, if the transactions herein contemplated are not consummated, each
party will continue to hold such information and documents in strict confidence
and shall return to such other party all such documents then in such receiving
party's possession (including the Schedules and Exhibits to this Agreement)
without retaining copies thereof; provided, that each party's obligations under
this Section 12.10 to refrain from such use and to maintain such confidentiality
shall not apply to any information or documents that are in the public domain
when furnished by the other or to be disclosed required by applicable law .

         12.11 Publicity. Seller and Purchaser each agree that, without the
written consent of the other, it will not issue a press release or otherwise
publicly disclose the transactions contemplated by this Agreement (including but
not limited to the Purchase Price) except as may be required by law. Any public
announcement of this Asset Purchase will be made by Purchaser and Seller jointly
and simultaneously, and the wording of any such announcement will be mutually
agreed upon unless, in the reasonable judgment of counsel for Purchaser, any
laws, rules or regulations to which Purchaser is subject (including the rules of
NASDAQ) mandate other wording, in which event such other laws, rules or
regulations as interpreted by Purchaser and its counsel shall control; provided,
however, that from and after the Closing, Purchaser shall be entitled to issue
press releases or otherwise publicly disclose its acquisition of the Business.

         12.12 Equitable Relief. Each party recognizes that the other is likely
to suffer irreparable damage if the provisions of Sections 12.10 or 12.11 are
not specifically enforced. In the event of a dispute concerning any of these
sections, each party agrees that the other may, without posting bond or
security, obtain an temporary or permanent injunction restraining the
consummation of any action or transaction prohibited thereby pending
determination of such dispute. The provisions of Sections 12.10 and 12.11 shall
likewise be enforceable by a decree of specific performance. In the event of
litigation relating to such provisions, if the court

                                       30
<PAGE>   31

determines that either party or any of its employees, agents or representatives
has breached any thereof, the injured party shall be entitled to recover from
the breaching party its reasonable fees, costs, and expenses (including attorney
fees) incurred in connection with the prosecution of any equitable or legal
proceedings and any appeal therefrom.

         12.13 Dispute Resolution. Subject to Section 12.12, any dispute under
this Agreement which is not settled by mutual agreement among the parties
hereto, shall be finally settled by binding arbitration, conducted by and in
accordance with the rules then in effect of the American Arbitration
Association. The costs of the arbitration, including administrative and
arbitrators' fees, shall be shared equally by the parties. Each party shall bear
its own costs and attorneys' and witness' fees. The prevailing party in any
arbitration, as determined by the arbitration panel, shall be entitled to an
award against the other party in the amount of the prevailing party's costs and
reasonable attorneys' fees. In making any such award, the arbitration panel
shall take into consideration the outcome of the proceeding and the
reasonableness of the conduct of each such party in connection with the dispute,
in light of the facts known to such party at the time such party engaged in such
conduct. The arbitration panel shall not have authority to award punitive
damages. The arbitration shall be held in Denver, Colorado.

         12.14 Captions. The captions and headings in this Agreement are for
convenience only and will not be considered in interpreting any provision of
this Agreement. Unless otherwise indicated, all article and section references
are to the articles and sections of this Agreement and all references to day are
to calendar days. Whenever under the terms of this Agreement, the time for
performance of a covenant or condition falls upon a Saturday, Sunday or Oklahoma
state holiday, such time for performance will be extended to the next business
day.

         12.15 Successors. This Agreement and all of the provisions of this
Agreement shall be binding upon and inure to the benefit of Purchaser and Seller
and their respective successors and permitted assigns. Neither this Agreement
nor any of the rights, interests or obligations under this Agreement may be
assigned by either of the parties to this Agreement without the prior written
consent of the other party. Nothing contained in this Agreement, express or
implied, is intended to confer upon any person or entity other than the parties
to this Agreement and their successors in interest and permitted assignees (if
any), any rights or remedies under or by reason of this Agreement.

         12.16 Waiver. Either Purchaser or Seller shall have the right to waive
any one or more conditions precedent to Closing and to proceed with the
transactions contemplated by this Agreement, without, however, releasing the
