         DEFICIENCY

12.1     For the purposes of this Agreement, "Force Majeure" means any of the
         following events or circumstances (i) not within the reasonable control
         of either party, (ii) which event or circumstance, despite the exercise
         of reasonable diligence, cannot be or be caused to be prevented,
         avoided or removed by either party, and (iii) does not arise out of

         at the time of entering into this Agreement:

         (vi)     any shortfall in utilities or other necessaries for the
                  operation of the Facility (except to the extent that such
                  failure is caused by or contributed to by an act or omission
                  on the part of MR3 or CEG).

12.2     A party shall be excused from performance and shall not be construed to
         be in default of any obligation hereunder so long as failure to perform
         such obligation is due to an event of Force Majeure.

         invoked such Force Majeure as a cause for such delay shall submit to
         the other party reasonable proof of the nature of such delay and its
         effect upon the time of performance.

         MR3 and CEG:

                  (i)      shall make all reasonable efforts to prevent and
                           reduce to a minimum and mitigate the effect of any
                           delay occasioned by any Force Majeure; and

                  (ii)     shall use their best efforts to ensure resumption of
                           normal performance of this Agreement after the

                           their obligations to the maximum extent practicable
                           as agreed between CEG and MR3.

                  (iii)    shall each have the option to terminate this
                           Agreement should such Force Majeure continue for a
                           period of 90 days. Any CEG Office Expenses due under
                           Section 1.3 above shall be advanced by MR3 during
                           such 90 day period.

                  to such information without an obligation of confidence or
                  non-disclosure, and without the information having been
                  solicited or obtained by any use of the Confidential
                  Information; or

13.3     Non-Disclosure to Third Parties - CEG shall keep the Confidential
         Information strictly confidential and in trust for MR3. CEG shall use
         its best efforts to safeguard the Confidential Information, taking at
         least the same strict precautions it would take to safeguard its own
         most valuable proprietary and confidential information.

         a)       CEG shall not disclose any portion of the Confidential
                  Information to any third party (that is not an employee
                  provided for below), unless MR3 specifically agrees in writing
                  in advance and the third party agrees in writing to be bound
                  to MR3 as CEG is bound by this Agreement (in its entirety) or
                  by terms substantially similar which are agreed upon by the
                  third party and MR3.

         b)       CEG shall immediately notify MR3 upon receiving any request
                  made by any non-authorized third party to disclose any
                  Confidential Information and shall cooperate with MR3 in its
                  efforts to protect the Confidential Information from
                  disclosure. Should any third party make any unauthorized use
                  of any Confidential Information provided hereunder, CEG shall
                  notify MR3 and cooperate in taking steps to protect the
                  Confidential Information from further unauthorized use.

         c)       CEG may disclose material to the extent required to be
                  disclosed pursuant to any governmental application or pursuant
                  to any final court order, provided however that CEG shall: I)
                  promptly notify MR3 upon its receipt of any pleading,
                  discovery request, interrogatory, motion or other paper that
                  requests or demands disclosure of the Confidential
                  Information, II) oppose any request for disclosure, and that
                  failing, seek to have access and use limited by a protective
                  order; and III) provide MR3 all reasonable opportunity and
                  assist MR3 in its efforts to contest any requirement of
                  disclosure, seek judicial protection against the disclosure
                  and have such disclosure as is required made under a
                  protective secrecy order.

13.4     Employee Access and Control of the Information - CEG agrees that only
         those CEG employees who need to know the Confidential Information will
         have access to same, and then only to the extent necessary to carry out
         their respective tasks. As part of its obligation to safeguard the
         Confidential Information, CEG agrees that prior to and as a condition
         of his or her access to the Confidential Information, each employee
         shall sign a Confidentiality Agreement. CEG shall keep copies of all
         such acknowledgments, and provide copies to MR3 immediately.

         Upon any termination of the Agreement between MR3 and CEG or at any
         time upon MR3's request, CEG agrees to stop use of the Confidential
         Information hereunder and to:

                  a)       Return promptly all documents and other tangible
                           materials provided by or under authorization of MR3
                           that contain evidence, record, derive from or reveal
                           any of the Confidential Information; and

                                                                              12

                  b)       Destroy all documents and other tangible materials
                           generated by CEG or its employees that evidence,
                           record, derive from or reveal any of the Confidential
                           Information. Upon request, CEG shall certify in
                           writing that such materials have been so returned or
                           destroyed.

13.5     Ownership of the Confidential Information - All Confidential
         Information, and all information that derives from it, is, shall be and
         will remain the exclusive property of MR3 until and unless some other
         agreement is made regarding that Confidential Information. This
         Agreement does not transfer any license or other right to use the
         Confidential Information other than pursuant to the Agreement, and does
         not obligate MR3 to provide any such rights in the future. If CEG
         either directly or indirectly through a third party makes, develops or
         contributes to any invention, application, technique, process,
         specification or work of authorship that is based on, improves upon, is
         derivative of or results from any use of the Confidential Information,
         CEG agrees to assign all rights therein to MR3, until or unless the
         parties enter into some other written agreement regarding the
         Confidential Information. CEG agrees to do what is reasonably necessary
         to perfect this assignment.

         which the parties declare to be known to them. The parties also agree
         that: (a) the appointing authority shall be the American Arbitration
         Association; (b) the number of arbitrators shall be three (3); (c) the
         language to be used in the arbitral proceedings shall be English. In
         any such arbitration proceeding, the arbitrators shall adopt and apply

         discovery so that each party shall allow and obtain discovery of any
         matter not privileged which is relevant to the subject matter involved
         in the arbitration to the same extent as if such arbitration were a
         civil action pending in a United States District Court. The decision of
         a majority of the arbitrators shall be final and binding on all of the
         parties. The attorney's fees, arbitrators' fees, costs, expenses, and

17.      ENTIRE AGREEMENT

         This Agreement constitutes the entire agreement between the parties
         concerning the subject matter hereof and supercedes and replaces the
         agreement entered into between the parties on June 18, 2002. If any one
         or more of the provisions contained in this Agreement shall, for any
         reason, be held to be invalid, illegal or unenforceable in any respect,
         such invalidity, illegality or unenforceability shall not affect any
         other provision of this Agreement, but this Agreement shall be
         construed as if such invalid, illegal or unenforceable provision had
         never been contained herein. If, moreover, any one or more of the
         provisions contained in this Agreement shall for any reason be held to
         be excessively broad as to time, duration, geographical scope, activity
         or subject, it shall be construed by limiting and reducing it, so as to
         be enforceable to the extent compatible with the applicable law as it
         shall then exist.

18.      REPRESENTATIONS AND WARRANTIES

         To the best of each party's knowledge, after due inquiry, each of MR3
         and CEG hereby represents, warrants and covenants to the other as
         follows:

         18.1     Right, Power and Authority. Each party has full right, power
                  and authority to enter into this Agreement and there is
                  nothing which would prevent it from performing its obligations
                  under the terms and conditions imposed on it by this
                  Agreement.

                                                                              14

         18.2     Binding Obligation. This Agreement has been duly authorized by
                  all necessary corporate or legal action of MR3 and CEG,
                  respectively, and constitutes a valid and binding obligation
                  on MR3 and CEG, respectively, enforceable in accordance with
                  the terms hereof.

         18.3     Good Standing. MR3 or CEG, as the case may be, is a
                  corporation or partnership duly organized and validly existing
                  and in good standing under the laws of its jurisdiction of
                  formation and is duly qualified and authorized to do business
                  wherever the nature of its activities or properties requires
                  such qualification or authorization.

         18.4     No Provisions Contravened. There is no provision in its
                  partnership, company or corporate charter, articles of
                  incorporation, By-Laws or equivalent governing documents, and
                  no provision in any existing mortgage, indenture, contract or
                  agreement binding on it which would be contravened by the
                  execution, delivery or performance by it of this Agreement.

         18.5     No Consent of Third Parties Needed. No consent of any third
                  party or holder of any of its indebtedness is or shall be
                  required as a condition to the validity of this Agreement.

         18.6     No Law Contravened. Neither its execution nor its delivery of
                  this Agreement nor its fulfillment of or compliance with the
                  terms and provisions hereto shall contravene any provision of
                  the laws of any jurisdiction, including, without limitation,
                  any statute, rule, regulation, judgment, decree, order,
                  franchise or permit applicable to it.

         18.7     Continued Effect of Representations and Warranties. It
                  covenants and agrees that its representations and warranties
                  contained in this Agreement shall remain true in all respects
                  for the Term hereof with the same effect as though such
                  representations and warranties had been made on and as of any
                  subsequent date during such Term.

         18.8     CEG collectively includes the operator and all the owners of
                  the Property and has the right to grant the exclusive
                  processing rights to MR3 hereunder, and CEG has not, and shall
                  not in the future during the Term of this Agreement, grant
                  such rights to any other person or entity.

19.      GOOD FAITH

         Each party diligently and in the utmost good faith agrees to perform
         its respective duties and obligations under this Agreement and to
         undertake all actions reasonably required to promote the intent of this
         Agreement. The parties each agree to provide all further information,
         and to execute, acknowledge and deliver all further documents and
         instruments, reasonably required to consummate the transactions
         contemplated hereunder.

IN WITNESS WHEREOF, the parties have caused this Agreement to be executed on the
date first written above by their duly authorized representatives.
