This Purchase and Sale Agreement (“Agreement”), dated March 31, 2009, is by and between Teton DJ LLC, a Colorado limited liability company, (“Seller” or “Teton DJ”) with an address of 600 17th Street, Suite 1600 North, Denver, Colorado 80202, and Noble Energy, Inc., a Delaware corporation (“Buyer” or “Noble”) with an address of 1625 Broadway, Suite 2200, Denver, Colorado 80202. The transaction contemplated by this Agreement may be referred to as the “Transaction.” Seller and Buyer may be referred to individually as a “Party” or collectively as the “Parties.” Teton Energy Corporation (“Teton Energy”) joins in this Agreement for the purposes of providing certain guarantees in accordance with existing agreements between the Parties.

RECITALS

A. Teton Energy and Noble entered into an Acreage Earning Agreement dated effective December 31, 2005 (the “Acreage Earning Agreement”) , providing for the earning by Noble of an interest in oil and gas leasehold properties owned by Teton Energy (the “Teton Leases”), the exploration for oil and gas, the drilling and operation of wells, the installation of production infrastructure, and the acquisition of oil and gas properties within an area of mutual interest (the “AMI”), among other matters, in Chase, Dundy, Keith and Perkins Counties, Nebraska and Sedgwick County, Colorado.

B. By First Amendment to Acreage Earning Agreement dated effective December 31, 2005 (the “Amendment”), among other matters, Teton Energy and Noble acknowledge that title to the Teton Leases is held by Teton DJ, a wholly owned subsidiary of Teton Energy and, therefore, Teton DJ should be a party to the joint operating agreements covering jointly owned oil and gas properties in the AMI.

C. The Amendment provides that Teton Energy agrees to indemnify, hold harmless and defend Noble from and against all losses whatsoever arising out of any failure on the part of Teton DJ to perform its obligations under joint operating agreements covering the jointly owned properties in the AMI.

D. Seller owns and desires to sell the Assets, as defined below, to Buyer upon the terms and conditions set forth in this Agreement.

E. Buyer desires to purchase the Assets pursuant to the terms and conditions of this Agreement.

ARTICLE 2
PURCHASE PRICE

2.1 Purchase Price. The Purchase Price for the Assets shall be Three Million Eight Hundred Thousand Dollars ($3,800,000.00) (the “Purchase Price”), subject to Section 2.2 below. Based on market valuations performed by independent third parties, and Seller’s reasonable judgment based on several factors, including but not limited to market solicitations, offers made to Seller, and expressions of interest made and received by Seller, the Purchase Price is fair and reasonable consideration for the Assets.

2.2 Adjustments to Purchase Price. The Purchase Price shall be adjusted at Closing according to this Section without duplication pursuant to a “Settlement Statement” approved by Seller and Buyer on or before Closing. A draft of the Settlement Statement will be prepared by Buyer and provided to Seller on or before Closing for Buyer’s comment and review.

i. An amount equal to all Property Expenses, including prepaid expenses, attributable to the Assets after the Effective Time that were paid by Seller (all to be apportioned as of the Effective Time except as otherwise provided), including without limitation, prepaid rentals and royalties, including lease rentals;

ii. The proceeds of production attributable to the Assets occurring before the Effective Time and received by Buyer, net of royalties and taxes measured by production;

i. An amount equal to all Property Expenses attributable to the Assets prior to the Effective Time that are paid by Buyer, subject to Section 2.2.c.;

ii. An amount equal to the sum of all Title Defect adjustments under Section 4.4.b.;

iii. An amount equal to the sum of all Environmental Defect adjustments under Section 5.3.b;

c. Final Allocation of Property Expenses. The Parties have agreed on the amount of all Property Expenses related to periods prior to the Effective Time, subject to the apportionment of Taxes as provided in Article 13, on an arms’ length basis and after adequate and sufficient inquiry and investigation. For purposes of this paragraph only, Property Expenses shall not include claims by third parties for additional royalties payable with respect to Seller’s interest in the Assets prior to the Effective Time.

2.3 Allocated Values. Buyer and Seller have agreed to allocate the Purchase Price among the Assets as follows, which amounts shall be referred to as the “Allocated Value.”

ARTICLE 3
DUE DILIGENCE REVIEW

3.1 Access to Records. Subject to Section 3.2, Seller will disclose and make available to Buyer and its representatives at Seller’s or Seller’s agent’s office and during Seller’s normal business hours, all Records in Seller’s possession or control relating to the Assets for the purpose of permitting Buyer to perform its due diligence review including, but not limited to, all title opinions, well, leasehold, unit, title, contract, division order, accounting, tax, gas marketing, vendor and creditor files. Seller agrees to cooperate with Buyer in Buyer’s efforts to obtain, at Buyer’s sole expense, such additional information relating to the Assets as Buyer may reasonably desire. Buyer may inspect the Records only to the extent it may do so without violating any obligation, confidence or contractual commitment of Seller to a third party. Seller shall use reasonable efforts to obtain the necessary consents to allow Buyer’s examination of any confidential information that is material to this transaction.

3.2 Representation and Warranty. Seller makes no representations regarding the accuracy of any of the Records; provided, however, Seller does represent that (i) all of the Records are files, or copies thereof, that Seller has used in the ordinary course of operating and owning the Assets, (ii) Seller has not intentionally withheld any material information in the Records and (iii) Seller has not intentionally misrepresented any material information in the Records. Except as set forth in this Section 3.2, no representation or warranty of any kind is made by Seller as to the Records and Buyer expressly agrees that any conclusions drawn therefrom shall be the result of its own independent review and judgment. The representations contained in this paragraph shall apply only to matters of fact, and shall not apply to any information, data, printouts, extrapolations, projections, documentation, maps, graphs, charts, or tables which reflect, depict, present, portray, or represent, or which are based upon or derived from, in whole or in part, interpretation of the Records including, but not limited to, matters of geological, geophysical, engineering, or scientific interpretation.

ARTICLE 4
TITLE MATTERS

4.1 Defensible Title. The term “Defensible Title” means such title to the Assets, that, subject to and except for Permitted Encumbrances: (i) entitles Seller to receive not less than the net revenue interest set forth on Exhibit B for each Well listed on Exhibit B (“NRI”); (ii) obligates Seller to bear costs and expenses relating to the maintenance, development, operation and the production of Hydrocarbons from each Well in an amount not greater than the working interest set forth in Exhibit B (“WI”); (iii) is not subject to reduction by virtue of the exercise by any third party of a reversionary interest, back in or similar right except as scheduled in Exhibit B; (iv) is free and clear of mortgages, encumbrances, liens, delinquent taxes and preferential rights to purchase or rights of first refusal unless the foregoing rights are waived by the holders thereof; (v) is not subject to unperformed drilling obligations except as expressly assumed by Buyer; and (vi) is not subject to defects or conditions that would create a material impairment of use or loss of interest in the affected Asset.

4.2 Permitted Encumbrances. The term “Permitted Encumbrances” shall mean:

a. lessors’ royalties, overriding royalties, net profits interests, production payments, reversionary interests and similar burdens if the net cumulative effect of such burdens does not operate to reduce the NRI set forth on Exhibit B;

b. liens for Taxes, or assessments, not yet due or delinquent;

c. all rights to consent by, required notices to, filings with, or other actions by federal, state and local governmental entities in connection with the ownership or operation of the Leases if the same are customarily obtained subsequent to such transfer of ownership or operations;

d. easements, rights-of-way, servitudes, permits, and surface leases on, over, or in respect of property owned or leased by Seller or over which Seller owns rights-of-way, easements, permits, or licenses that are of record in the applicable county to the extent such matters, individually or in the aggregate, do not materially interfere with oil and gas operations on the Leases and do not materially affect the value thereof;

e. rights of reassignment upon the surrender or expiration of any Lease;

f. the terms and conditions of the Material Agreements to the extent such do not decrease the NRI for the affected Asset or increase the WI for such Asset without a corresponding proportionate increase in the NRI for such Asset; and

g. any encumbrance, title defect or matter waived or deemed waived by Buyer pursuant to Section 4.4.a.

4.3 Title Defects. The term “Title Defect” means any encumbrance, encroachment, irregularity, defect in or objection to real property title, excluding Permitted Encumbrances, that alone or in combination with other defects renders title to an Asset less than Defensible Title.

4.4 Adjustments for Title Defects.

a. Notice of Title Defects. Buyer shall deliver to Seller a written “Notice of Title Defects” on or before March 31, 2009. The Notice of Title Defects shall describe the Title Defect and state the reduction in the Allocated Value of an Asset caused by the Title Defect (the “Defect Value”). Other than matters which are violative of Seller’s special warranty of title set out in Exhibit I, any matters not described in a written Notice of Title Defect shall conclusively be deemed to have been waived and accepted by Buyer, and shall be deemed Permitted Encumbrances hereunder. In determining the Defect Value, the Parties intend to include only that portion of the Asset affected by the Title Defect. The Defect Value may not exceed the Allocated Value of the Asset and shall be determined by the Parties in good faith, taking into account all relevant factors, including without limitation the following:

i. If the Title Defect is a lien or encumbrance on the Asset created by Seller, and such lien or encumbrance is unconditionally released at or prior to Closing, there shall be no Defect Value associated with such lien or encumbrance.

ii. If the Title Defect is an actual reduction in NRI or any other matter that does not fall within the matters described in subsection i., then the Buyer will rerun its ARIES based calculation (or similar program) that resulted in the Allocated Value for the affected portion of the Assets using the same economic and engineering criteria except as changed to accommodate the Title Defect to calculate the impact on the Allocated Value for the affected Asset. This revised calculation of the Allocated Value will be presented to Seller, and Buyer and Seller will act in good faith to reach mutual agreement as to the diminution effect of the Title Defect and thus the Defect Value.

b. Defect Adjustments. With respect to adjustments to the Purchase Price for Title Defects, the Parties agree as follows:

i. “Excluded Assets” are Assets excluded from this Agreement pursuant to Sections 4.4.b.iii and 5.3.b.

ii. Seller shall have the option of attempting to cure Title Defects to the reasonable satisfaction of Buyer on or before the Closing Date, which option shall be communicated to Buyer prior to the Closing Date.

iii. If Seller does not elect to cure or cannot cure a Title Defect to Buyer’s reasonable satisfaction, Buyer shall have the option to either accept assignment of the Asset affected by a Title Defect, and the Purchase Price shall be adjusted downward by the Defect Value, or to exclude such Asset from this Agreement. If Buyer elects to exclude such Asset, the Purchase Price shall be adjusted downward by an amount equal to the Allocated Value of the Excluded Asset.

4.5 Dispute Resolution. The Parties agree to resolve disputes concerning the following matters pursuant to this Section 4.5: (i) the existence of a Title Defect, (ii) the adequacy of Title Defect curative materials submitted pursuant to Section 4.4.b, and (iii) the amount of a Defect Value (collectively, the “Disputed Defect Matters”). The Parties agree to attempt to initially resolve all disputes through good-faith negotiations. Subject to Buyer’s and Seller’s right to terminate this Agreement under Article 10 prior to Closing, if the Parties cannot resolve such disputes on or before Closing, the Disputed Defect Matters shall be submitted to binding arbitration in accordance with the procedures set forth in Section 14.5.d. In such event, an amount equal to the Defect Values associated with the Disputed Defect Matters shall be withheld from the Purchase Price paid by Buyer to Seller at Closing, and the affected Assets shall be retained by Seller at Closing. If, following binding arbitration, the Seller is obligated to sell and the Buyer is obligated to purchase the Assets or portions of the Assets affected by a Disputed Defect Matter, the closing date for the affected Assets shall occur within ten (10) Business Days following the decision of the arbitrators or as otherwise agreed to by the Parties. “Business Day” means a day on which commercial banks located in Denver, Colorado are open for business. Notwithstanding the foregoing, Closing shall occur on March 31, 2009 as to Assets which are not affected by a Disputed Defect Matter, subject, however, to the rights of Seller and Buyer to terminate this Agreement under Article 10.

4.6 Casualty Loss. After the Effective Time and prior to Closing, if a portion of the Assets is destroyed by fire or other casualty, or is taken or threatened to be taken in condemnation or under the right of eminent domain, (with such event being a “Casualty Loss”), Buyer shall purchase the Asset at Closing for the Allocated Value of the Asset reduced by the estimated cost to repair or replace such Asset (with equipment of similar utility). In no event shall the watering out of a well, casing collapse, or breakage of equipment constitute a Casualty Loss.

ARTICLE 5

c. Environmental Defect. “Environmental Defect” means a condition in, on or under the Assets (including, without limitation, air, land, soil, surface and subsurface strata, surface water, ground water, or sediments) attributable to a period of time prior to the Effective Time that causes any portion of the Assets to be in material violation of an Environmental Law or requires Remediation under an Environmental Law.

Buyer shall provide Seller prior written notice of any environmental inspections and tests, including sampling activities, and Buyer shall give Seller the opportunity to participate in all such inspections and tests. Buyer shall provide Seller, at no cost to Seller, all reports of environmental inspections and tests, provided that all such reports shall be deemed to be confidential between the parties and subject to the confidentiality provisions of Section 8.6.a of this Agreement. Buyer agrees to release, indemnify, defend, and hold harmless Seller against all Losses (as defined in Section 14.3) arising from or related to the activities of Buyer, its employees, agents, contractors and other representatives in connection with Buyer’s Environmental Assessment regardless of the negligence or strict liability of Seller.

5.3 Adjustments for Environmental Defects Pre-Closing.

a. Notice of Environmental Defects. Buyer shall provide Seller with written notice of any Environmental Defect which Buyer’s Environmental Assessment reveals and will provide evidence thereof. Such notice and evidence shall be given on or before March 31, 2009. Buyer will be deemed to have conclusively waived the right to adjust the Purchase Price with respect to any Environmental Defect about which it fails to notify Seller in writing prior to March 31, 2009.

Any Remediation of an Environmental Defect shall be conducted by or under the supervision of Buyer. In no event will Buyer have any obligation to remediate any such Environmental Defect unless Buyer expressly agrees in writing to do so. There shall be no reduction to the Purchase Price until such time as the sum of all Environmental Defect Values exceeds Seventy-Five Thousand Dollars ($75,000) (the “Environmental Threshold Amount”) but, in such event, the Purchase Price reduction shall include the Environmental Threshold Amount.

5.4 Environmental Dispute Resolution Pre-Closing. The parties agree to resolve disputes concerning the following matters pursuant to this Section: (i) the existence and scope of Environmental Defect, (ii) Buyer’s estimate of costs of Remediation of an Environmental Defect and (iii) the effectiveness of Remediation. The parties agree to attempt to initially resolve all disputes through good faith negotiations. If the parties cannot resolve disputes regarding items (i), (ii) or (iii) on or before the Closing Date, the disputed matters will be finally determined by binding arbitration pursuant to Section 14.5.d.

5.5 Seller’s Indemnity.

a. Seller shall indemnify, hold harmless, release and defend Buyer from and against all damages, losses, claims, demands, causes of action, judgments and other costs (including but not limited to any civil fines, penalties, costs of assessment, clean-up, removal and remediation of pollution or contamination, and expenses for the modification, repair or replacement of facilities on the Lands) brought by any and all persons and any agency or other body of federal, state or local government, on account of any personal injury, illness or death, any damage to, destruction or loss of property, and any contamination or pollution of natural resources (including soil, air, surface water or groundwater) to the extent any of the foregoing directly or indirectly is caused by or otherwise involves any environmental condition of the Assets or Lands, which is created and arises prior to Closing, including, but not limited to, the presence, disposal or release of any material (whether hazardous, extremely hazardous, toxic or otherwise) of any kind in, on or under the Assets or the Lands before Closing (the “Pre-Closing Environmental Liabilities”).

After the Closing, Buyer and Seller shall indemnify each other as follows:

a. Seller’s Indemnification of Buyer.

a. Coverage. Such indemnity shall extend to all Losses suffered or incurred by the indemnified party.

b. Claim Notice. The Party seeking indemnification under the terms of this Agreement (“Indemnified Party”) shall submit a written “Claim Notice” to the other Party (“Indemnifying Party”) stating: (i) the amount of each payment claimed by an Indemnified Party to be owing, (ii) the basis for such claim, with supporting documentation, and (iii) a list identifying to the extent reasonably possible each separate item of Loss for which payment is so claimed. The amount claimed shall be paid by the Indemnifying Party to the extent required herein within 30 days after receipt of the Claim Notice, or after the amount of such payment has been finally established, whichever last occurs.

c. Information.

d. Dispute. Other than with respect to a Claim based on an issue for which another method of dispute resolution is provided in this Agreement, if the existence of a valid Claim or amount to be paid by an Indemnifying Party is in dispute, the Parties agree to submit determination of the existence of a valid Claim or the amount to be paid pursuant to the Claim Notice to binding arbitration in Denver, Colorado, such arbitration to be conducted as follows: The arbitration proceeding shall be governed by Colorado law and shall be conducted in accordance with the Commercial Arbitration Rules of the American Arbitration Association (“AAA”), though it need not be administered by the AAA.

Assignor hereby grants and transfers to Assignee, its successors and assigns, to the extent so transferable and permitted by law, the benefit of and the right to enforce the covenants, representations and warranties, if any, which Assignor is entitled to enforce with respect to the Assets, but only to the extent not enforced by Assignor.

6. Governmental Forms of Assignment. Assignor and Assignee may execute separate governmental form assignments of the Assets on officially approved forms, in sufficient counterparts to satisfy applicable statutory and regulatory requirements.

The interests conveyed by such separate assignments are the same, and not in addition to, the Assets conveyed herein.

7. Further Assurances. Assignor shall execute, acknowledge and deliver or cause to be executed, acknowledged and delivered such instruments and take such other action as may be reasonably necessary or advisable to carry out the purposes and intents of this Assignment. Teton Energy Corporation joins in this Assignment as further assurance to Assignee that all right, title and interest of Teton DJ, whether legal or equitable, in the Assets is hereby assigned.

8. Successors and Assigns. This Assignment binds and inures to the benefit of Assignor and Assignee and their respective successors and assigns.
