Purchase.

     

    Subject
to the terms and conditions hereof, at the Closing Seller hereby agrees to sell
the Interest to Purchaser, and Purchaser agrees to purchase the Interest from
Seller, for a total purchase price of Twenty Million Dollars (US$20,000,000)
(the “Purchase
Price”).  Purchaser agrees that it will pay the Purchase Price
as follows:  (a) Thirteen Million Five Hundred
Thousand Dollars (US$13,500,000) (the “Initial Payment”)
shall be paid by Purchaser to Seller at the Closing by wire transfer of
immediately available funds to an account designated in writing to Purchaser by
Seller and (b) Six Million Five Hundred
Thousand Dollars (US$6,500,000) (the “Post-Closing
Payment”) shall be paid by Purchaser to Seller, by wire transfer of
immediately available funds to an account designated in writing to Purchaser by
Seller, within ten (10) days of the earlier to occur of (i) the satisfaction,
expiration, termination or waiver by MERC, by August 29, 2008, of the
contingency set forth in MERC’s Anchor Shipper Offer Sheet, which is attached to
Exhibit B to the Precedent Agreement for Firm Natural Gas Transportation Service
dated May 22, 2008 by and between MERC and Bison or (ii) the execution, on or
before the Approval Date, of one or more third-party firm transportation
precedent agreements with an aggregate maximum delivery quantity of at least 50
MMcf per day from the Powder River Basin on terms and conditions no less
favorable than those offered to shippers in the Bison Open Season and having no
material conditions outstanding or not otherwise satisfied, other than
conditions that are within the control of Purchaser (the “Alternate
Agreements”); provided that such Alternate
Agreements may include a firm transportation precedent agreement by MERC to
transport at least 50 MMcf per day on either the Bison Project or the Pathfinder
Project that is a substitute arrangement for that described in clause (i) of
this sentence if such agreement by MERC contains terms and conditions no less
favorable than those offered to shippers in the Bison Open Season and has no
material conditions outstanding or not otherwise satisfied, other than
conditions that are within the control of Purchaser.  For the
avoidance of doubt, it is acknowledged and agreed that Purchaser will only be
required to pay the
Post-Closing Payment upon satisfaction of the conditions set forth in either of
clauses (b)(i) or (ii) of this Section 2.1, and that
if the conditions set forth in neither of such clauses are satisfied, the
Purchase Price will consist only of the Initial Payment.

    Purchaser
represents and warrants to Seller as follows:

     

    4.1           Organization.

     

    Purchaser
is a corporation duly organized, validly existing, and in good standing under
the laws of the State of Nevada.

     

    4.2           Authority.

     

    Purchaser
has the full corporate power and authority to enter into this Agreement and to
perform its obligations hereunder.  The execution, delivery and
performance of this Agreement by Purchaser have been duly and validly authorized
by all necessary corporate action.  Assuming the due and valid
authorization, execution and delivery of this Agreement by Seller, this
Agreement constitutes the legal, valid and binding obligation of Purchaser,
enforceable against Purchaser in accordance with its terms, except as such
enforceability may be limited by (a) applicable bankruptcy, insolvency,
reorganization, moratorium and other laws of general application affecting
enforcement of creditors’ rights generally and (b) laws relating to the
availability of equitable remedies.

     

    4.3           No Conflicts or Violations;
Consents.

     

    Neither
the execution and delivery of this Agreement by Purchaser nor the performance by
Purchaser of its obligations hereunder (a)conflicts
or will conflict with, or constitutes or will constitute a violation of, the
certificate or articles of incorporation, bylaws or other organizational
document of Purchaser, (b) conflicts or will conflict with, constitutes or will
constitute a breach of or default under (or an event that, with notice or lapse
of time or both, would constitute such a breach of or default under), or
provides or will provide any party the right to accelerate, terminate, modify or
cancel, any indenture, mortgage, deed of trust, loan agreement, lease or other
agreement or instrument to which Purchaser is a party, by which Purchaser is
bound or to which any of its properties or assets is subject, (c) violates or
will violate any statute, law, ordinance, regulation, order, judgment, decree or
injunction of any court or Governmental Body to which Purchaser or any of its
properties or assets may be subject or (d) will result in the creation or
imposition of any Lien upon any of the property or assets of
Purchaser.  Purchaser is not required to provide any notice to or
obtain any Consent from any Person in connection with the consummation of the
Contemplated Transactions, except for such notices or Consents where the failure
to provide such notice or obtain such Consent would not reasonably be expected
to impair its ability to consummate the Contemplated Transactions.

    4.4           Certain
Proceedings.

     

    There is
no pending Proceeding that has been commenced against Purchaser that challenges,
or may have the effect of preventing, delaying, making illegal or otherwise
interfering with, any of the Contemplated Transactions.  To the
Knowledge of Purchaser, no such Proceeding has been Threatened.

     

    4.5           Brokers or
Finders.

     

    Purchaser
and its officers and agents have incurred no obligation or liability, contingent
or otherwise, for brokerage or finders’ fees or agents’ commissions or other
similar payment in connection with this Agreement.

Access.

     

    Purchaser
acknowledges that (a) the Interest has not been registered under the Securities
Act of 1933, as amended (the “Securities Act”), or
any state securities laws, and (b) Seller has disclosed to Purchaser that the
Interest may not be resold absent such registration or unless an exemption from
registration is available.  Purchaser is acquiring the Interest for
its own account, for investment purposes only and not with a view to its
distribution within the meaning of the Securities Act.  Purchaser has
such knowledge and experience in financial and business matters that it is
capable of evaluating the merits and risks of the Contemplated
Transactions.  Seller has made available to Purchaser and its
Representatives the opportunity to ask questions of the officers and
Representatives of Seller, to engage in diligence and to acquire such additional
information about the business, assets and financial condition of Seller as
Purchaser has requested, and all such requested information has been received by
Purchaser.

    5.2           Pathfinder
Project.

     

    Provided

otherwise satisfied by August 31, 2008 (unless otherwise extended by Purchaser),
other than conditions that are within the control of Purchaser, and (b)
Purchaser has not, by September 30, 2008 (or such other later date agreed to by

will, subject to the rights and obligations of Bison set forth in the Precedent
Agreements for Firm Natural Gas Transportation Service executed with the Bison
shippers, use commercially reasonable efforts to complete the Bison Project and

    5.3           Northern Border Pipeline
Company Capacity.

efforts to assist Purchaser after the Closing by marketing existing capacity on

shippers, including, but not limited to, shippers on the Bison Project and/or
the Pathfinder Project.  Commercially reasonable efforts shall consist
of (a) the continuation at least until September 30, 2008 of the offer to all
shippers of a discounted reservation rate on Seller’s pipeline system of US$0.23
per MMBtu for transportation from Port of Morgan to Ventura for a ten (10) year
commitment, (b) initiating the applicable right of first refusal process for
capacity on Seller’s pipeline system to Chicago during the month of September
2008 and (c) Seller offering the market, including, but not limited to, shippers
on the Bison Project and/or the Pathfinder Project, an open season having a bid
period during the month of August 2008 proposing the expansion of Seller’s
pipeline system for transportation on Seller’s pipeline system to Chicago for a
ten (10) year commitment with a targeted in-service date of the fourth quarter
of 2010, or as soon as practicable thereafter.  Such capacity shall be
offered at a rate that the Seller reasonably believes to be marketable; provided that Seller’s
obligation under this Agreement to undertake any such expansion shall be subject
to a fair and reasonable return analysis by Seller relating to the expected
economics of any such expansion and the approval of its Management
Committee.

     

    5.4           Discussions with
Shippers.

     

    Seller
shall assist Purchaser in discussions with the existing shippers on the Bison
Project in order to assist with the satisfaction of the outstanding conditions
precedent under such shippers’ firm transportation precedent agreements and
encourage their participation in the Pathfinder Project; provided that Seller’s
obligations pursuant to this Section 5.4 shall be
expressly limited to participating in conversations and shall not include any
obligation to undertake or incur any liabilities or expenses or to make
concessions of any kind to shippers.

     

    5.5           Further
Assurances.

     

    Each
party agrees (a) to furnish upon request to the other party such further
information, (b) to execute and deliver to the other party such other documents
and (c) to do such other acts and things, in each case as the other party may
reasonably request for the purpose of carrying out the intent of this Agreement
and the Contemplated Transactions.

Matters.

     

    The
following provisions shall govern the allocation of responsibility between
Seller and Purchaser for certain Tax matters following the Closing

(a)     Tax
Returns.

     

     (i)           Seller
shall prepare or cause to be prepared and file or cause to be filed all Tax
Returns for Bison for periods ending on or before the Closing Date that are
required to be filed after the Closing Date, and shall be responsible for the
timely payment (and entitled to any refund) of Taxes due with respect to the
period covered by such Tax Returns.

     

     (ii)           Seller
shall prepare or cause to be prepared and file or cause to be filed any Tax
Returns of Bison for periods which begin before the Closing Date and end after

taxable year or period that begins before and ends after the Closing Date, the
determination of the Taxes for the portion of the year or period ending on, and
the portion of the year or period beginning after, the Closing Date shall be
determined by assuming that the taxable year or period ended on and included the
Closing Date, except that exemptions, allowances or deductions that are
calculated on an annual basis and annual property taxes shall be prorated on the
basis of the number of days in the annual period elapsed through the Closing
Date as compared to the number of days in the annual period elapsing after the
Closing Date.

     

     (iv)           Any
Tax Return to be prepared pursuant to the provisions of this Section 5.6 shall be
prepared in a manner consistent with practices followed in prior years with
respect to similar Tax Returns, except for changes required by changes in law or
fact.  Purchaser shall not file an amended Tax Return for any period
ending on or prior to the Closing Date without the consent of Seller, which
consent shall not be unreasonably withheld or delayed.

     

      
(b)        Transfer
Taxes.  Purchaser shall be responsible for the payment of all
excise, sales, use, transfer (including real property transfer or gains), stamp,
documentary, filing, recordation and other similar taxes, together with any
interest, additions or penalties with respect thereto and any interest in
respect of such additions or penalties, resulting directly from the Contemplated

(c)        Access to
Information.  After the Closing Date, Seller shall grant to
Purchaser (or its designees) access at all reasonable times to all of the

shall afford Purchaser (or its designees) the right (at Purchaser's expense) to

permit Purchaser (or its designees) to prepare Tax Returns and to conduct
negotiations with taxing authorities.  After the Closing Date,
Purchaser shall grant or cause Bison to grant to Seller (or its designees)
access at all reasonable times to all of the information, books and records
relating to Bison within the possession of Purchaser or Bison (including work
papers and correspondence with taxing authorities), and shall afford Seller (or
its designees) the right (at Seller’s expense) to take extracts therefrom and to
make copies thereof, to the extent reasonably necessary to permit Seller (or its
designees) to prepare Tax Returns and to conduct negotiations with taxing
authorities.

     

      
(d)        Survival.  Anything
to the contrary in this Agreement notwithstanding, the representations,
warranties, covenants, agreements, rights and obligations of the parties with
respect to any Tax matter covered by this Agreement shall survive the Closing

or incurred by or with respect to Bison or its assets with respect to the period
prior to and including the Closing Date, (2) attributable to a breach by Seller
of any covenant with respect to Taxes in this Agreement or (3) attributable to a

refund shall, within ninety (90) days after receipt of such refund, remit it to

    7.4           Waiver.

     

    Neither
the failure to exercise, nor any delay in exercising, any right, power or
privilege by either party under this Agreement shall operate as a waiver of such
right, power, or privilege, and no single or partial exercise of any such right,
power or privilege shall preclude any other or further exercise of such right,
power or privilege or the exercise of any other right, power, or
privilege.  To the maximum extent permitted by applicable law, except
as otherwise expressly provided herein, (a) no claim or right arising out of
this Agreement can be discharged by one party, in whole or in part, by a waiver
or renunciation of the claim or right unless in writing signed by the other
party, (b) no waiver that may be given by a party shall be applicable except in
the specific instance for which it is given and (c) no notice to or demand on
one party shall be deemed to be a waiver of any obligation of such party or of
the right of the party giving such notice or demand to take further action
without notice or demand as provided in this Agreement.

     

    7.5           Entire Agreement and
Modification.

     

    This
Agreement supersedes all prior agreements between the parties with respect to
its subject matter and constitutes a complete and exclusive statement of the
terms of the agreement between the parties with respect to its subject
matter.  This Agreement may not be amended except by a written
agreement executed by each of the parties.

     

    7.6           Assignments; Successors; No
Third-Party Rights.

     

    Neither
party may assign any of its rights under this Agreement without the prior
consent of the other party; provided that Purchaser may
assign its rights to any Affiliate of Purchaser without Seller’s consent so long
as Purchaser
remains obligated to Seller pursuant to the terms and conditions of this
Agreement and such Affiliate expressly assumes the obligations of Purchaser
hereunder.  Any attempted assignment of this Agreement or any of the
rights hereunder in violation of the foregoing shall be voidable by the
non-assigning party.  Subject to the preceding sentences, this
Agreement will apply to, be binding in all respects upon, and inure to the
benefit of the successors and permitted assigns of the
parties.  Nothing expressed or referred to in this Agreement will be
construed to give any Person other than the parties to this Agreement any legal
or equitable right, remedy or claim under or with respect to this Agreement or
any provision of this Agreement.  This Agreement and all of its
