COVENANTS OF THE PARTIES

Section 6.1                                    Due Diligence Review.

(a)                                 Subject to the other provisions of this Section 6.1, upon execution of this Agreement, Seller will make the Assets available to Purchaser and its Representatives for inspection and review, at Purchaser’s sole cost, to permit Purchaser to perform its due diligence (“Due Diligence Review”) as hereinafter provided.  Purchaser shall be entitled to conduct its Due Diligence Review until the Claim Date (the “Due Diligence Period”).

(b)                                 Upon reasonable advance notice, the Records will be made available to Purchaser at the offices of Seller during Seller’s normal business hours.  Notwithstanding the foregoing, Records relating to Non-Op Properties will only be made available to Purchaser to the extent such Records are in Seller’s possession, provided that Seller will cooperate with and assist Purchaser in obtaining copies of any Records not within Seller’s possession relating to such Non-Op Properties.

(c)                                  Seller hereby consents to Purchaser conducting, during the Due Diligence Period and upon reasonable advance notice to Seller, at Purchaser’s sole risk and expense, on-site inspections and an Environmental Assessment of the Assets, provided that (x) Purchaser’s right to conduct due diligence on Assets operated by any Person other than Seller (the “Non-Op Properties”) shall be subject to obtaining such operator’s consent, which Seller will use commercially reasonable efforts to obtain (but which efforts will not require Seller to pay any consent fee to the operator or agree to give such operator any other financial concession), and (y) any such Environmental Assessment will be subject to the following:

(i)                                     Purchaser shall not conduct any sampling, boring, drilling or other invasive investigation activities upon the Assets (“Invasive Activities”) without the prior written consent of Seller, which consent will not be unreasonably withheld, conditioned or delayed and, with respect to any Non-Op Property, without the prior written consent of the third-party operator thereof, which Seller will use commercially reasonable efforts to obtain (but which efforts will not require Seller to pay any consent fee to the operator or agree to give such operator any other financial concession).

(ii)                                  If any Environmental Assessment indicates that a Condition exists or is reasonably likely to exist on any Asset, Purchaser may request Seller’s consent to conduct Invasive Activities (“Inspection Request”).  The Inspection Request shall include the specific Asset that would be subject to the Invasive Activities, the reasons for requesting Invasive Activities and a description of the proposed Invasive Activities to be conducted by Purchaser.  Seller shall consent to or deny the Inspection Request within three Business Days of receipt of the Inspection Request, provided that consent from Seller shall not be unreasonably withheld, conditioned or delayed and that the failure of Seller to respond within such three Business Day period shall be deemed to constitute

11

Seller’s denial of consent to the Inspection Request and the proposed Invasive Activities; and provided, further, Purchaser’s right to conduct Invasive Activities on any Non-Op Property is also subject to the prior written consent of the third-party operator of such property, which Seller will use commercially reasonable efforts to obtain (but which efforts will not require Seller to pay any consent fee to the operator or agree to give such operator any other financial concession).

(d)                                 Seller shall have the right to have its Representatives present at any time that Purchaser or any of its Representatives are present on the Assets, and Purchaser will cooperate reasonably with Seller’s scheduling requests so Seller or its Representatives can be present.  In connection with any Environmental Assessment or Invasive Activities, Purchaser agrees not to interfere with the normal operation of the Assets and agrees to comply with all requirements and safety policies of the operator.  If Purchaser or its agents prepares an Environmental Assessment or conducts Invasive Activities, Purchaser will furnish a copy of the assessment or report resulting therefrom to Seller.  The Parties shall execute a “common undertaking” letter regarding the confidentiality of Environmental Assessments and Invasive Activities.

(f)                                   As a condition for granting Purchaser or any Representative thereof access to any Asset, Purchaser must present Seller with a customary insurance certificate confirming that it is adequately insured including the insurer’s waiver of subrogation of Purchaser’s or its Representatives’ rights and claims against Seller.

(g)                                  PURCHASER HEREBY WAIVES, RELEASES AND AGREES TO DEFEND AND INDEMNIFY SELLER GROUP AGAINST ALL CLAIMS FOR INJURY TO, OR DEATH OF, PERSONS OR FOR DAMAGE TO PROPERTY ARISING IN ANY WAY FROM THE ACCESS AFFORDED TO PURCHASER HEREUNDER OR THE ACTIVITIES OF PURCHASER OR ITS REPRESENTATIVES (INCLUDING INVASIVE ACTIVITIES), EXCLUDING CLAIMS INVOLVING THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF ANY MEMBER OF SELLER GROUP.  This waiver, release and indemnity by Purchaser shall survive termination of this Agreement.

(h)                                 EXCEPT FOR THE SPECIFIC REPRESENTATIONS AND WARRANTIES CONTAINED IN THIS AGREEMENT, SELLER MAKES NO WARRANTY OR REPRESENTATION OF ANY KIND AS TO ANY INFORMATION OBTAINED BY PURCHASER PURSUANT TO THIS SECTION 6.1, INCLUDING THE RECORDS AND ANY INFORMATION CONTAINED THEREIN.  PURCHASER

(b)                                 Subject to Section 6.2(a) and except as otherwise provided in this Section 6.2(b), unless Seller obtains the prior written consent of Purchaser to act otherwise, which consent shall not be unreasonably withheld, conditioned or delayed, Seller will use commercially reasonable efforts within the constraints of the applicable operating agreements and other applicable Contracts not to: (i) abandon any part of the Assets; (ii) except for those operations set forth on Schedule 4.7, approve or otherwise commit to any operations on the Assets anticipated in any instance to cost more than $100,000 per activity (excepting emergency operations required under presently existing contractual obligations, ongoing commitments under existing AFEs and operations undertaken to avoid a monetary penalty or forfeiture provision of any applicable agreement or order all of which shall be deemed to be approved, provided that Seller immediately notifies Purchaser of any emergency operation or operation to avoid monetary penalty or forfeiture excepted herein); (iii) convey or dispose of any part of the Assets (other than replacement of equipment or sale of Hydrocarbons produced from the Assets in the ordinary course of business); (iv) enter into any Material Contract in respect of an Asset, or materially amend or change the terms of any Contract or Lease; (v) unless required by Law or a Governmental Body, plug or abandon any of the Wells; (vi) voluntarily relinquish its position as operator to anyone other than Purchaser with respect to any of the operated Assets; (vii) waive, compromise or settle any claims, demands, complaints, causes of action, suits, actions, judgments, awards, recoveries, settlements, and appeals, which can reasonably be expected to materially affect the ownership, operation or value of the Assets after the Closing Date; or (viii) issue any note, bond, or other debt instrument secured by the Assets or agree to the imposition of any security interest or Lien on the Assets or allow any encumbrance which would impose a security interest or Lien on account of unpaid amounts upon any of the Assets that will not be repaid at the Closing.

(c)                                  Requests for approval of any action restricted by this Section 6.2 shall be delivered to the following individual, who shall have full authority to grant or deny such requests for approval on behalf of Purchaser:

13

Section 6.3                                    Consents to Assignment and Preferential Rights to Purchase.

(a)                                 Promptly after the Execution Date (but no later than three Business Days thereafter), Seller shall prepare and send (i) notices to the holders of any required consents to assignment requesting consents to, (A) if not already obtained, the transfer of the Assets from Liberty to Kodiak Williston pursuant to the Liberty PSA and (B) the Conveyances and (ii) notices to the holders of any applicable preferential rights to purchase or similar rights with respect to the Conveyances, in each case, in compliance with the terms of such rights and requesting waivers of such rights.  Seller shall use commercially reasonable efforts to cause such consents to assignment and waivers of preferential rights to purchase or similar rights (or the exercise thereof) to be obtained and delivered prior to Closing (provided that Seller shall not be obligated to make any payments or undertake obligations in connection with the obtaining of such consents and waiver of preferential rights); and shall provide Purchaser with copies of all notices sent pursuant to this Section 6.3(a) and, promptly after Sellers’ receipt thereof (but no later than three Business Days thereafter), any responses from the holders of such consents and preferential purchase rights (or similar rights), as applicable, to such notices.  Purchaser shall reasonably cooperate with Seller in seeking to obtain such consents to assignment and waivers of preferential rights.  Any preferential purchase right must be exercised subject to all terms and conditions set forth in this Agreement, including the successful Closing of this Agreement pursuant to ARTICLE 8 as to those Assets for which preferential purchase rights have not been exercised.  The consideration payable under this Agreement for any particular Asset for purposes of preferential purchase right notices shall be the Allocated Value for such Asset, subject to adjustment pursuant to Section 3.4.  If, prior to the Closing Date, any Party discovers any required consents or preferential rights to purchase (applying to the Assets) for which notices have not been delivered pursuant to the first sentence of this Section 6.3(a), then (A) the Party making such discovery shall provide the other Party with written notification of such consents or preferential rights, as applicable, (B) Seller, following delivery or receipt of such written notification, will promptly send notices to the holders of the required consents requesting consents to the Conveyances and notices to the holders of preferential rights to purchase in compliance with the terms of such rights and requesting waivers of such rights and (C) the terms and conditions of this Section 6.3 shall apply to the Assets subject to such consents or preferential rights to purchase, as applicable.

(b)                                 In no event shall there be included in the Conveyances any Asset for which a Specified Consent Requirement has not been satisfied with respect to the transactions described in Section 6.3(a)(i).  In cases in which the Asset subject to such a requirement is a Contract and Purchaser is assigned the Lease, Well or Unit to which the Contract relates, but the Contract is not transferred to Purchaser due to the unwaived Specified Consent Requirement, (i) Seller shall continue after Closing to use commercially reasonable efforts to satisfy the Specified Consent Requirement so that such Contract can be transferred to Purchaser upon receipt of the Specified Consent Requirement (provided that Seller shall not be obligated to make any payments or undertake obligations in connection with satisfying such Specified Consent Requirements) and (ii) the Contract shall be held by Seller for the benefit of Purchaser until the Specified Consent Requirement is satisfied or the Contract has terminated.  In cases in which the Asset subject to such a Specified Consent Requirement is a Property and such consent is not satisfied by Closing, the affected Property and the Assets primarily related to that Property shall

14

not be transferred at Closing and the Unadjusted Purchase Price shall be reduced by the Allocated Value of the Property and related Assets.  If an unsatisfied Specified Consent Requirement with respect to which an adjustment to the Unadjusted Purchase Price is made under Section 3.4 is subsequently satisfied prior to the date of delivery of the final settlement statement under Section 8.4(b), a separate closing shall be held within five Business Days thereof at which (i) Seller shall convey the affected Property and related Assets to Purchaser in accordance with this Agreement and (ii) Purchaser shall pay an amount equal to the Allocated Value of such affected Property and related Assets, adjusted in accordance with Section 3.4, to Seller.  If such consent requirement is not satisfied by the date of delivery of such final settlement statement, Seller shall have no further obligation hereunder to sell and convey such Property and related Assets and Purchaser shall have no further obligation hereunder to purchase, accept and pay for such Property, and the affected Property and related Assets shall be deemed to be deleted from the applicable Exhibits and Schedules to this Agreement for all purposes.

(c)                                  If any preferential right to purchase any Assets is exercised prior to Closing, the Unadjusted Purchase Price shall be decreased by the Allocated Value for such Assets, and the affected Assets shall be deemed to be deleted from the applicable Exhibits and Schedules to this Agreement for all purposes.  Seller shall retain the consideration paid by the Third Party, and shall have no further obligation with respect to such affected Assets under this Agreement.  Should a Third Party fail to exercise its preferential right to purchase as to any portion of the Assets prior to Closing and the time for exercise or waiver has not yet expired, the affected Assets shall not be transferred at Closing and the Unadjusted Purchase Price shall be reduced by the Allocated Values of such Assets.  In the event that such Third Party exercises its preferential right to purchase following the Closing, Seller shall have no further obligation to sell and convey the affected Assets and Purchaser shall have no further obligation to purchase, accept and pay for such affected Assets, and the affected Assets shall be deemed to be deleted from the applicable Exhibits and Schedules to this Agreement for all purposes.  If, on the other hand, the applicable preferential purchase rights are waived or expire, a separate closing shall be held within five Business Days thereof at which (i) Seller shall convey the affected Assets to Purchaser in accordance with this Agreement and (ii) Purchaser shall pay an amount equal to the Allocated Value of such Assets, adjusted in accordance with Section 3.4, to Seller.  In the event that the applicable preferential purchase rights are not exercised, waived or expired by 90 days after the Closing, Seller shall have no further obligation hereunder to sell and convey the Assets subject to the such preferential purchase rights and Purchaser shall have no further obligation hereunder to purchase, accept and pay for such Assets, and the affected Assets shall be deemed to be deleted from the applicable Exhibits and Schedules to this Agreement for all purposes.

Section 6.4                                    Defect Matters.

(a)                                 Defects.  Purchaser will have the right to assert Defects pursuant to this Section 6.4(a) for the purpose of (x) making an adjustment to the Unadjusted Purchase Price pursuant to Section 3.4(b)(vi) and (y) determining whether the closing condition in Section 7.2(e) has been satisfied.  Except as set forth in the preceding sentence and the special warranty of title provided in the Conveyance, and without prejudice to Purchaser’s rights under Section 10.2(b), Purchaser hereby acknowledges and agrees that Purchaser will have no other remedy for any Defect with respect to any of the Leases, Wells, Units and other Assets and Purchaser hereby releases and waives all other remedies and agrees not to assert or threaten to assert any claim

15

with respect to any such waived remedies.

(i)                                     To assert a claim for a Defect for such purpose, Purchaser must deliver a claim notice to Seller (a “Defect Notice”) promptly after the discovery thereof, but in no event later than five Business Days prior to the Closing (such cut-off date, the “Claim Date”).  Each Defect Notice shall be in writing and include (a) a description of the alleged Defect that is reasonably sufficient for Seller to determine the basis of the alleged Defect, (b) the Asset adversely affected by the Defect (a “Defect Property”), (c) all documents upon that Purchaser relies for its assertion of a Defect, including supporting documents reasonably necessary for Seller to verify the existence of the alleged Defect, and (d) the amount by which Purchaser reasonably believes the value of each Defect Property is reduced by the alleged Defect (the “Defect Amount”) and the computations and information upon which Purchaser’s belief is based.  Seller shall have the opportunity to cure any Title Defects, to Purchaser’s reasonable satisfaction, on or before one Business Day prior to the Closing and any such cured Title Defects will no longer be considered Defects for purposes of this Agreement.  The Defect Amount shall be determined as provided in Section 6.4(a)(ii) and Section 6.4(a)(iii), as applicable, provided that, notwithstanding anything to the contrary in this Section 6.4, the aggregate Defect Amount, in the case of Section 6.4(a)(ii) only, attributable to all Title Defects upon any Defect Property shall not exceed the Allocated Value of such Defect Property.

(ii)                                  The Defect Amount for any Title Defect shall be based on the amount by which the Allocated Value of the Defect Property affected by such Title Defect is reduced as a result of the existence of such Title Defect and shall be determined in accordance with the following methodology, terms and conditions: (A) if Purchaser and Seller agree on the Defect Amount, that amount shall be the Defect Amount; (B) if the Title Defect is a Lien that is undisputed and liquidated in amount, then the Defect Amount shall be the amount of the payment necessary to remove such Title Defect from the Defect Property; and (C) if the Title Defect represents an obligation, encumbrance, burden or charge upon or other defect in title to the Defect Property of a type not described in subsections (A) or (B) above, the Defect Amount shall be determined by taking into account the following factors: (1) any discrepancy between (x) the Net Revenue Interest or Working Interest for any Defect Property and (y) the Net Revenue Interest or Working Interest stated in Exhibit A or Exhibit B, respectively; (2) the Allocated Value of the Defect Property; (3) the portion of the Defect Property affected by the Title Defect; (4) the legal effect of the Title Defect; (5) the values placed upon the Title Defect by Purchaser and Seller; (6) any discrepancy between (x) the Net Acre interest covered by a Lease and (y) the Net Acre interest covered by such Lease stated in Exhibit A; and (7) such other reasonable factors as are necessary to make a proper evaluation.

(iii)                               The Defect Amount for any Environmental Defect shall be based on the reasonable cost to remediate such Environmental Defect.  In no event shall the Defect Amount for any Environmental Defect for a particular Defect Property exceed the reasonable cost to remediate such Environmental Defect. The Defect Amount for any Environmental Defect shall be determined without duplication of any costs or losses included in another Environmental Defect, Defect Amount or Casualty Loss hereunder.

16

(b)                                 Title Benefits.  Seller will have the right to assert rights, circumstances or conditions that operate to (i) increase the Net Revenue Interest of Seller in any Lease, Well, or Unit above that shown in Exhibit A or Exhibit B, respectively, to the extent the same does not cause a greater than proportionate increase in Seller’s Working Interest therein above that shown in Exhibit A or Exhibit B respectively, (ii) decrease the Working Interest of Seller in any Lease, Well, or Unit below that shown in Exhibit A or Exhibit B, respectively, to the extent that such decrease in Seller’s Working Interest does not cause a decrease in Seller’s Net Revenue Interest therein below that shown in Exhibit A or Exhibit B, respectively, or (iii) increase the Net Acres of Seller covered by a Lease (other than due to an increase in Seller’s Working Interest that is not accompanied by a proportionate increase in Seller’s Net Revenue Interest) above that shown in Exhibit A (each, a “Title Benefit”).  Title Benefits may be asserted hereunder for the purposes of offsetting (x) any Defect Amounts used to determine the Title Defect Adjustment Amount pursuant to Section 6.4(d) and (y) Defect Amounts used to determine whether the closing condition in Section 7.2(e) has been satisfied.  To assert a Title Benefit, Seller must deliver a claim notice to Purchaser (a “Title Benefit Notice”) promptly after the discovery thereof, but in no event later than Claim Date.  Each Title Benefit Notice shall be in writing and include (a) a description of the alleged Title Benefit that is reasonably sufficient for Purchaser to determine the basis of the alleged Title Benefit, (b) the Asset affected by the Title Benefit (a “Title Benefit Property”), (c) all documents upon that Seller relies for its assertion of a Title Benefit, including supporting documents reasonably necessary for Purchaser to verify the existence of the Title Benefit, and (d) the amount by which Seller reasonably believes the value of each Title Benefit Property is increased by the Title Benefit (the “Title Benefit Amount”) and the computations and information upon which Seller’s calculation is based.  The Title Benefit Amount resulting from a Title Benefit shall be determined in accordance with the same methodology, terms and conditions for determining the Defect Amount with respect to a Title Defect.

(c)                                  Remedies.  Subject to Seller’s right to dispute resolution under Section 6.4(f), in the event that any Defect is timely asserted by Purchaser in accordance with Section 6.4(a)(i), and is not waived by Purchaser or timely cured by Seller prior to Closing under Section 6.4(a)(i), Seller shall convey the Defect Property to Purchaser at Closing and the Defect Amount for such Defect Property shall be taken into account in the determination of the Defect Adjustment Amount pursuant to Section 6.4(d) and Section 6.4(e); provided, however, that in the event the Defect Amount asserted exceeds the Allocated Value for the relevant Defect Property, Seller may elect prior to Closing to exclude such Defect Property from the transaction and reduce the Unadjusted Purchase Price by the Allocated Value for such Defect Property pursuant to Section 3.4(b)(viii).

(d)                                 Title Defect Adjustment Amount.  If the aggregate Defect Amount of all Title Defects (disregarding any Defect whose Defect Amount is less than $100,000) exceeds the aggregate Title Benefit Amount of all Title Benefits (disregarding any Title Benefit whose Title Benefit Amount is less than $100,000), then the Unadjusted Purchase Price shall be reduced to the extent (and only to the extent) such excess exceeds $1,250,000 (such excess amount, if any, the “Title Defect Adjustment Amount”) pursuant to Section 3.4(b)(vi).  The Title Defect Adjustment Amount shall be recalculated as part of the final determination of the Adjusted Purchase Price under Section 8.4(b) to take into account the resolution of Disputed Defects and Disputed Title Benefits pursuant to Section 6.4(f).

17

(e)                                  Environmental Defect Adjustment Amount.  If the aggregate Defect Amount of all Environmental Defects (disregarding any Defect whose Defect Amount is less than $100,000) exceeds $1,250,000, then the Unadjusted Purchase Price shall be reduced to the extent (and only to the extent) such excess exceeds $1,250,000 (such excess amount, if any, the “Environmental Defect Adjustment Amount”, and together with the Title Defect Adjustment Amount, “Defect Adjustment Amount”) pursuant to Section 3.4(b)(vi).  The Environmental Defect Adjustment Amount shall be recalculated as part of the final determination of the Adjusted Purchase Price under Section 8.4(b) to take into account the resolution of Disputed Defects pursuant to Section 6.4(f).

(f)                                   Defect Dispute Resolution.

(i)                                     The Parties agree to resolve disputes concerning the following matters pursuant to this Section 6.4(f):  (A) the existence and scope of a Defect, Title Benefit or Defect Adjustment Amount; (B) the Defect Amount for a Defect Property or the Title Benefit Amount for a Title Benefit Property; and (C) the adequacy of Seller’s Title Defect curative efforts as to whether a Title Defect continues to exist or Purchaser’s reasonable satisfaction of such efforts (the “Defect Disputed Matters”).

(ii)                                  The Parties agree to attempt to initially resolve all Defect Disputed Matters through negotiations between the Parties.  If the Parties cannot resolve a Defect or Title Benefit dispute on or before Closing (each, a “Disputed Defect” and a “Disputed Title Benefit,” respectively), solely for purposes of determining the Closing Payment (and subject to the final calculation of the Defect Adjustment Amount as part of the final determination of the Adjusted Purchase Price under Section 8.4(b)), the Defect Adjustment Amount shall be calculated as if Purchaser’s position on each Disputed Defect were correct and as if Seller’s position with respect to each Disputed Title Benefit were correct (the resulting amount, the “Closing Date Defect Adjustment”); and, following Closing, the Defect Disputed Matters will be finally determined by binding arbitration as described in Section 6.4(f)(iii).

(iii)                               The Defect Disputed Matters will be finally determined by binding arbitration pursuant to Section 12.2(b), provided, however, that the independent arbitrator appointed pursuant to Section 12.2(b) shall be (A) in the case of Disputed Defects that are Title Defects or Disputed Title Benefits, an oil and gas title attorney licensed in North Dakota with a minimum of ten years’ experience with title defects affecting the types of properties which are the subject of the Defect Disputed Matters and (B) in the case of Disputed Defects that are Environmental Defects, an environmental attorney qualified by education, knowledge and experience with environmental defects affecting the types of properties which are subject to the Disputed Defects and having a minimum of ten years’ experience with such types of defects and properties.  The arbitrator shall employ such independent attorneys, petroleum engineers and/or other consultants as deemed necessary.  Notwithstanding anything to the contrary set forth in Section 12.2(b) (x) on or before 45 days after Closing, Purchaser and Seller shall present their respective positions in writing to the arbitrator, together with such evidence as each Party deems appropriate, and (y) the arbitrator shall resolve the dispute through a final decision within 20 days after submission of the matters in dispute and the final decision shall be reflected in the

18

final calculation of the Adjusted Purchase Price pursuant to Section 8.4(b).

Section 6.5                                    Casualty Loss.  If, prior to Closing, a portion of the Assets is destroyed by fire or other casualty or if a portion of the Assets is taken or threatened to be taken in condemnation or under the right of eminent domain (a “Casualty Loss”), Purchaser shall not be obligated to purchase such Asset.  If Purchaser declines to purchase such Asset, the Purchase Price shall be reduced by the Allocated Value of such Asset and such Asset will be deemed an Excluded Asset.  If Purchaser elects to purchase such Asset, the Purchase Price shall be reduced by the estimated cost to repair such Asset (with equipment of similar utility), less all insurance proceeds which shall be payable to Purchaser, up to the Allocated Value thereof (the reduction being the “Net Casualty Loss”).  Seller, at its sole option, may elect to cure such Casualty Loss prior to Closing and, in such event, Seller shall be entitled to all insurance proceeds in connection therewith.  If Seller elects to cure such Casualty Loss, such election shall be at Seller’s sole cost and expense and Seller may replace any personal property that is the subject of a Casualty Loss with equipment of similar grade and utility, or replace any real property with real property of similar nature and kind if such property is acceptable to Purchaser in its sole discretion.  If Seller elects to cure the Casualty Loss and cures such Casualty Loss prior to Closing, Purchaser shall purchase the affected Asset at Closing for the Allocated Value thereof.

Section 6.6                                    Liberty PSA Matters.  Seller shall communicate regularly with Purchaser with respect to any matters arising under or otherwise relating to the Liberty PSA or the Assets.  Except with Purchaser’s prior consent, Seller shall not (a) amend, restate, supplement or otherwise modify the Liberty PSA as to the Assets or in a manner that would be adverse to Purchaser in connection with the terms of Section 10.3 or (b) waive any rights and remedies available to Seller that relate to the Assets under the Liberty PSA or in a manner that would be adverse to Purchaser in connection with the terms of Section 10.3.

Section 6.7                                    Public Announcements; Confidentiality.

(a)                                 Subject to Section 6.7(b), neither Party shall make any press release or other public announcement regarding the existence of this Agreement, the contents hereof or the transactions contemplated hereby without the prior written consent of the other Party (collectively, the “Public Announcement Restrictions”).  The Public Announcement Restrictions shall not restrict disclosures to the extent (i) necessary for a Party to perform this Agreement (including disclosures to Governmental Bodies or Third Parties holding preferential rights to purchase, rights of consent or other rights that may be applicable to the transaction contemplated by this Agreement, as reasonably necessary to provide notices, seek waivers, amendments or termination of such rights, or seek such consents), (ii) required (upon advice of counsel) by applicable securities or other Laws or regulations or the applicable rules of any stock exchange having jurisdiction over the Parties or their respective Affiliates or (iii) that such Party has given the other Party a reasonable opportunity to review such disclosure prior to its release and no objection is raised.  In the case of the disclosures described under subsections (i) and (ii) of this Section 6.7(a), each Party shall use its reasonable efforts to consult with the other Party regarding the contents of any such release or announcement prior to making such release or announcement.

(b)                                 The Parties shall keep all information and data relating to this Agreement

19

and the transactions contemplated hereby strictly confidential except for (i) disclosures to Representatives of the Parties (in which event, the disclosing Party will be responsible for making sure that the Representatives keep such information and data confidential), and (ii) any disclosures required to perform this Agreement (collectively, the “Confidentiality Restrictions”).  The Confidentiality Restrictions shall not restrict disclosures that are required (upon advice of counsel) by applicable securities or other Laws or regulations or the applicable rules of any stock exchange having jurisdiction over the Parties or their respective Affiliates.

Section 6.8                                    Replacement of Bonds, Letters of Credit and Guaranties.  The Parties understand that none of the bonds, letters of credit and guaranties, if any, posted by Seller with Governmental Bodies or co-owners and relating to the Assets will be transferred to Purchaser.  Promptly following Closing, but, as to Assets operated by Seller, in no event later than the transfer of operatorship of such Assets, Purchaser shall obtain, or cause to be obtained in the name of Purchaser, replacements for such bonds, letters of credit and guaranties, to the extent such replacements are necessary to permit the cancellation of the bonds, letters of credit and guaranties posted by Seller or to consummate the transactions contemplated by this Agreement.

Section 6.9                                    Operatorship.  Within three Business Days after Closing, Seller shall send notices to co-owners of those Assets that Seller currently operates indicating that Seller is resigning as operator, effective upon the Closing Date, and recommending that Purchaser be elected successor operator.

Section 6.10                             Suspense Accounts.  Prior to Closing, Seller will provide to Purchaser (a) information regarding all of Seller’s accounts holding moneys in suspense together with a written explanation (as contained in Seller’s files) of why such moneys are held in suspense or other information identifying the proper disposition of such moneys and (b) Seller’s division of interest and all supporting documentation regarding those royalty owners and working interest owners in the Leases for whom Seller disburses proceeds of production.  Following Closing, Purchaser shall be solely responsible for the proper distribution of such moneys held in suspense to the party or parties which or who are entitled to receive payment of the same, and hereby agrees to indemnify, defend and hold Seller harmless from any Damages therefor.

Section 6.11                             Transition Services.  Between the Execution Date and the Closing Date, the Parties will negotiate a form of transition services agreement (“Transition Services Agreement”) to be executed at Closing by the Parties, establishing the terms under which Seller would provide certain transition accounting services in respect of the Assets for a limited period of time following the Closing.  If the Parties do not reach an agreement regarding such a Transition Services Agreement prior to Closing, the Closing shall nonetheless occur (subject to the satisfaction of the conditions for Closing set forth herein) and, thereafter, until October 30, 2013, Seller shall provide transition accounting services for the Assets to Purchaser on substantially the same terms and conditions (as if Seller was the service provider, and Purchaser the service recipient, thereunder) as set forth in the Liberty TSA.

Section 6.12                             Further Assurances.  After Closing, the Parties agree to take such further actions and to execute, acknowledge and deliver all such further documents as are reasonably requested by the other Party for carrying out the purposes of this Agreement or of any document delivered pursuant to this Agreement. In addition, at the request of Purchaser, Seller agrees to

20

assist Purchaser in collecting the Third Party Costs, which such assistance shall include providing supporting documentation to substantiate the Third Party Costs, identifying the proper Third Party responsible for payment of such Third Party Costs, the date, if any, when such Third Party Costs are due, an aging of such Third Party Costs and such other information as Purchaser may reasonably request.

Adjustment but otherwise using Seller’s calculation of the other components of the purchase price, adjusted to reflect agreed upon resolution of any disputed item.  All other adjustments to the Unadjusted Purchase Price not determined as of Closing shall be taken into account as provided in Section 8.4(b).  The estimate set forth in the final preliminary settlement statement shall constitute the U.S. Dollar amount to be paid by Purchaser to Seller at the Closing (the “Closing Payment”).

(b)                                 Seller shall prepare and deliver to Purchaser a statement setting forth the final calculation of the Adjusted Purchase Price and showing the calculation of each adjustment, based, to the extent possible, on actual credits, charges, receipts and other items before and after the Effective Time no later than the 90th day following the Closing Date.  Seller shall, at Purchaser’s request, supply reasonable documentation available to support any credit, charge, receipt or other item included in such statement.  Purchaser shall deliver to Seller a written report containing any changes that Purchaser proposes be made to Seller’s statement no later than the 60th day following Purchaser’s receipt thereof.  Seller may deliver a written report to Purchaser during this same period reflecting any changes that Seller proposes to be made to such statement as a result of additional information received after the statement was prepared.  The Parties shall undertake to agree on the final statement of the Adjusted Purchase Price no later than 195 days after the Closing Date.  In the event that the Parties cannot reach agreement within such period of time, either Party may refer the remaining matters in dispute to the Denver, Colorado office of a mutually-agreed upon accounting firm for review and final determination by arbitration.  The accounting firm shall conduct the arbitration proceedings in Denver, Colorado in accordance with the Commercial Arbitration Rules of the American Arbitration Association, to the extent that such rules do not conflict with the terms of this Section 8.4.  The accounting firm’s determination shall be made within 30 days after submission of the matters in dispute and shall be final and binding on both Parties, without right of appeal.  In determining the proper amount of any adjustment to the Unadjusted Purchase Price, the accounting firm shall not increase the Unadjusted Purchase Price more than the increase proposed by Seller nor decrease the Unadjusted Purchase Price more than the decrease proposed by Purchaser, as applicable.  The accounting firm shall act as an expert for the limited purpose of determining the specific disputed matters submitted by the Parties and may not award damages or penalties to the Parties with respect to any matter.  The Parties shall each bear its own legal fees and other costs of presenting its case.  Seller shall bear one-half and Purchaser shall bear one-half of the costs and expenses of the accounting firm.  Within ten days after the earlier of (i) the expiration of Purchaser’s 60-day review period without delivery of any written report or (ii) the date on which the Parties finally determine the Adjusted Purchase Price or the accounting firm finally determines the disputed matters, as applicable, (A) Purchaser shall pay to Seller the amount by which the Adjusted Purchase Price exceeds the Closing Payment or (B) Seller shall pay to Purchaser the amount by which the Closing Payment exceeds the Adjusted Purchase Price, as applicable.  Any post-closing payment pursuant to this Section 8.4(b) shall bear interest from the Closing Date to the date of payment at the Prime Rate.

(c)                                  Purchaser shall assist Seller in the preparation of the final statement of the Adjusted Purchase Price under Section 8.4(b) by furnishing invoices, receipts, reasonable access to personnel, and such other assistance as may be requested by Seller to facilitate such process post-Closing.

24

(d)                                 All payments made or to be made under this Agreement to Seller shall be made by electronic transfer of immediately available funds to the accounts designated by Seller.  All payments made or to be made hereunder to Purchaser shall be by electronic transfer or immediately available funds to a bank and account specified by Purchaser in writing to Seller.

ARTICLE 9
TERMINATION

Section 9.1                                    Termination.  This Agreement may be terminated at any time prior to Closing: (a) by the mutual prior written consent of the Parties; or (b) by either Party if Closing has not occurred on or before 75 days after the Execution Date.  However, no Party shall be entitled to terminate this Agreement under clause (b), immediately above, if the Closing has failed to occur because such Party negligently or willfully failed to perform or observe in any material respect its covenants or agreements hereunder.

(a)                                 From and after Closing, Purchaser shall indemnify, defend and hold harmless the Seller Group from and against all Damages incurred, suffered by or asserted against such Persons: (i) caused by or arising out of or resulting from the Assumed Liabilities; (ii) caused by or arising out of or resulting from Purchaser’s breach of any of Purchaser’s covenants or agreements contained herein; or (iii) caused by or arising out of or resulting from any breach of any representation or warranty made by Purchaser contained in ARTICLE 5 or in the certificate delivered by Purchaser at Closing pursuant to Section 8.3(d).

(b)                                 From and after Closing, Seller shall indemnify, defend and hold harmless the Purchaser Group from and against all Damages incurred, suffered by or asserted against such Persons: (i) caused by or arising out of or resulting from the Seller Retained Liabilities; (ii) caused by or arising out of the Liberty Indemnified Matters (but only to the extent relating to the Assets); (iii) caused by or arising out of or resulting from Seller’s breach of Seller’s covenants or agreements contained herein; or (iv) caused by or arising out of or resulting from any breach of any representation or warranty made by Seller contained in ARTICLE 4, or in the certificate delivered by Seller at Closing pursuant to Section 8.2(c).

(c)                                  Notwithstanding anything to the contrary set forth herein, Seller shall have no liability for indemnification hereunder or for any Damages pursuant to Section 10.2(b)(iii) and (iv) until the total of all Damages with respect to such matters exceeds $750,000 (the “Deductible”), after which point the Purchaser Group shall be entitled to indemnification only in excess of the Deductible.  The aggregate liability of Seller for indemnification pursuant to Section 10.2(b)(iii) and (iv) with respect to Damages suffered by Purchaser Group shall not exceed $8,200,000 (the “Cap”).  Notwithstanding the foregoing, the Deductible and the Cap will not apply to Seller’s obligation to indemnify Purchaser for the Seller Retained Liabilities, or for indemnification relating to Seller’s breach of representations and warranties contained in Section 4.1, Section 4.2, Section 4.3, Section 4.4, and Section 4.5.

(d)                                 Notwithstanding anything to the contrary contained in this Agreement, from and after Closing, Seller’s and Purchaser’s sole and exclusive remedy against each other with respect to breaches of the representations, warranties, covenants and agreements of the Parties contained in ARTICLE 4, ARTICLE 5 and ARTICLE 6, and the affirmations of such representations and warranties, covenants, and agreements contained in the certificates delivered by each Party at Closing pursuant to Section 8.2(c) and Section 8.3(d), as applicable, is set forth in this Section 10.2, and if no such right of indemnification is expressly provided, then such claims are hereby waived to the fullest extent permitted by Law.  Except for the remedies contained in this Section 10.2, and any other remedies available to the Parties at law or in equity for breaches of this Agreement other than ARTICLE 4, ARTICLE 5 and ARTICLE 6, upon Closing, each Party releases, remises, and forever discharges the other Party from any and all suits, legal or administrative proceedings, claims, demands, damages, Damages, costs, liabilities, interest, or causes of action whatsoever, in law or in equity, known or unknown, which such

26

Parties might now or subsequently may have, based on, relating to, or arising out of this Agreement or Seller’s ownership, use, or operation of the Assets, or the condition, quality, status, or nature of the Assets, INCLUDING RIGHTS TO CONTRIBUTION OR COST RECOVERY UNDER THE COMPREHENSIVE ENVIRONMENTAL RESPONSE, COMPENSATION AND LIABILITY ACT OF 1980, AS AMENDED, BREACHES OF STATUTORY AND IMPLIED WARRANTIES, NUISANCE OR OTHER TORT ACTIONS, RIGHTS TO PUNITIVE DAMAGES, COMMON LAW RIGHTS OF CONTRIBUTION, ANY RIGHTS UNDER INSURANCE POLICIES ISSUED OR UNDERWRITTEN BY THE OTHER PARTY OR ANY OF ITS AFFILIATES. THE FOREGOING INDEMNITIES WILL APPLY AND BE EFFECTIVE EVEN IF THE DAMAGES COVERED THEREBY ARE CAUSED OR ARISE FROM, IN WHOLE OR IN PART, BY THE NEGLIGENCE (WHETHER SOLE, JOINT OR CONCURRENT), STRICT LIABILITY OR OTHER LEGAL FAULT OF ANY INDEMNIFIED PERSON, INVITEE OR THIRD PERSON, AND WHETHER OR NOT CAUSED BY A PRE-EXISTING CONDITION, BUT EXCLUDING, IN EACH CASE, THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF ANY INDEMNIFIED PERSON.

(e)                                  EACH PARTY CONFIRMS THAT IT IS NOT RELYING ON ANY REPRESENTATION OR WARRANTY OTHER THAN THOSE EXPRESSLY SET FORTH IN THIS AGREEMENT, AND EACH PARTY ACKNOWLEDGES THAT THIS NO RELIANCE CONFIRMATION IS A MATERIAL INDUCEMENT TO THE OTHER PARTY’S WILLINGNESS TO ENTER INTO THIS AGREEMENT AND CONSUMMATE THE TRANSACTIONS CONTEMPLATED HEREBY.

Section 10.3                             Liberty Indemnified Matters.

(a)                                 Seller is entitled to certain indemnity protections from Liberty under Section 14.2 of the Liberty PSA, including indemnity protections in respect of certain retained liabilities of Liberty and breaches by Liberty of certain representations, warranties, covenants and agreements set forth in the Liberty PSA (together with the events giving rise thereto, collectively, the “Liberty Indemnified Matters”).  Seller has agreed to indemnify Purchaser under Section 10.2(b)(ii) for the Liberty Indemnified Matters (as such matters relate to the Assets), with it being the intent of the Parties that such indemnification be provided from Seller to Purchaser hereunder in the same manner as if Purchaser was entitled to such indemnity protections as a party (with respect to the Assets) to the Liberty PSA.

(b)                                 In the event that Purchaser asserts a Liberty PSA Indemnity Claim, Seller shall promptly exercise (if not already exercised) all rights and seek all remedies available under the Liberty PSA for the Liberty Indemnified Matter to which such Liberty PSA Indemnity Claim relates.  In cases in which the Liberty PSA Indemnity Claim asserted by Purchaser is a Liberty PSA Non-Deductible Claim, the Damages for which Purchaser will be entitled to indemnification hereunder for such Liberty PSA Non-Deductible Claim will be the same amounts or other remedies (in each case, if and as recovered from Liberty) for which Seller is entitled to indemnification under the Liberty PSA in respect of such claim.  Alternatively, in cases in which the Liberty PSA Indemnity Claim asserted by Purchaser is a Liberty PSA Deductible Claim, the Damages for which Purchaser is entitled to indemnification under Section 10.2(b)(ii) for such Liberty PSA Indemnity Claim will be determined as set forth below:

27

(i)                                     Prior to the time at which the aggregate Liberty PSA Deductible Claim Amounts exceed the Liberty PSA Deductible, Purchaser will not be entitled to indemnification under Section 10.2(b)(ii) for any Damages for the Liberty PSA Deductible Claim.

(ii)                                  Following the time at which the aggregate Liberty PSA Deductible Claim Amounts exceed the Liberty PSA Deductible, but prior to the time at which such Liberty PSA Deductible Claim Amounts exceed the Liberty PSA Cap (such time period, the “Liberty Indemnity Period”), Purchaser will be entitled to indemnification under Section 10.2(b)(ii) for the Liberty PSA Deductible Claim in an amount equal to the Claiming Party Amount (if and as recovered from Liberty under the Liberty PSA) determined pursuant to Section 10.3(c)(i) (without prejudice to Purchaser’s rights to receive Non-Claiming Party Amounts pursuant to Section 10.3(c)(ii) that may be attributable to any such Liberty PSA Deductible Claim).

(iii)                               Following the time at which the aggregate Liberty PSA Deductible Claim Amounts exceed the Liberty PSA Cap, Purchaser will not be entitled to any further indemnification under Section 10.2(b)(ii) for any Damages for the Liberty PSA Deductible Claim.

(c)                                  It is acknowledged and understood that a Party’s recovery for a Liberty PSA Deductible Claim may be limited due to it bearing a disproportionate portion of the Liberty PSA Deductible for such indemnity claim (or previously asserted Liberty PSA Deductible Claims).  To avoid such disproportionate treatment, the Parties agree that, during the Liberty Indemnity Period, each time a Liberty PSA Deductible Claim is asserted, the Parties will be entitled to the amounts (if and when received by Liberty under the Liberty PSA, which, in the case of Purchaser, will be remitted by Seller) determined below in respect of such Liberty PSA Deductible Claim:

(i)                                     The Party making the Liberty PSA Deductible Claim will be entitled to an amount determined as follows (the “Claiming Party Amount”):

Where:

28

(ii)                                  The other Party will be entitled to an amount determined by subtracting the Claiming Party Amount from, subject to Section 10.3(c)(iii), the relevant Liberty PSA Deductible Claim Amount (the “Non-Claiming Party Amount”).

(iii)                               If a portion of any Liberty PSA Deductible Claim Amount is not recoverable due to it comprising a portion of the Liberty PSA Deductible, the Liberty PSA Deductible Claim Amount, for purposes of determining the Non-Claiming Party Amount under Section 10.3(c)(ii), will not include such non-recoverable amount.  Similarly, if a portion of any Liberty PSA Deductible Claim Amount is not recoverable due to it comprising a portion of the Liberty PSA Cap, the Liberty PSA Deductible Claim Amount, for purposes of determining (A) item “A” in the formula set forth in Section 10.3(c)(i) for the Claiming Party Amount and (B) the Non-Claiming Party Amount under Section 10.3(c)(ii) will not include, in each case, the non-recoverable amount.

Section 10.4                             Limitation on Actions.  The representations and warranties of the Parties in ARTICLE 4 and ARTICLE 5 and the covenants and agreements of the Parties in ARTICLE 6 and the corresponding representations and warranties given in the certificate delivered at Closing pursuant to Section 8.2(c) and Section 8.3(d) shall survive the Closing for a period of nine months, except that (i) the representations and warranties in Section 4.1, Section 4.2, Section 4.3, Section 4.4, Section 4.5, Section 5.1, Section 5.2, Section 5.3, Section 5.4 and Section 5.5 shall survive indefinitely, and (ii) the covenants and agreements, as applicable, in Section 6.7 and Section 6.12 shall survive indefinitely.  The remainder of this Agreement shall survive the Closing without time limit except (a) as may otherwise be expressly provided herein and (b) for the provisions of ARTICLE 11, which shall survive Closing until the applicable statute of limitations closes the taxable year to which the subject Taxes relate plus 90 days.  The representations, warranties, covenants and agreements of this Agreement shall be of no further force and effect after the date of their expiration, provided that there shall be no termination of any bona fide claim asserted pursuant to this Agreement with respect to such a representation, warranty, covenant or agreement prior to its expiration date.  The indemnities in Section 10.2(a)(ii), Section 10.2(a)(iii), Section 10.2(b)(iii) and Section 10.2(b)(iv) shall terminate as of the termination date of each respective representation, warranty, covenant or agreement that is subject to indemnification thereunder, except in each case as to matters for which a specific written claim for indemnity has been delivered to the indemnifying Party on or before such termination date.  The indemnity in Section 10.2(a)(i), Section 10.2(b)(i) and Section 10.2(b)(ii) shall continue without time limit.

Section 10.5                             Procedure.  The indemnifications contained in Section 10.2 and Section 10.3 shall be implemented as follows:

(a)                                 Claim Notice.  The Party seeking indemnification under the terms of this Agreement (the “Indemnified Party”) shall submit a written “Claim Notice” to the other Party (the “Indemnifying Party”) which, to be effective, must be delivered prior to the end of the survival period applicable to the representation or warranty, if applicable, that is the subject of

29

the Claim Notice and must state the amount of each payment asserted by the Indemnified Party to be owing, the basis for such claim with supporting documentation, and a list of each separate item of loss for which payment is so claimed.

(b)                                 Claims under Section 10.2.  Upon receipt of an effective Claim Notice, the Indemnifying Party must within 60 days:

(i)                                     contest the indemnification claim asserted in the Claim Notice, with such disputes to be resolved by written agreement of the Parties or final arbitration in accordance with Section 12.2(b);

(ii)                                  object to the sufficiency of information contained in the Claim Notice and request specified additional information reasonably necessary for it to assess such Claim Notice, which information the Indemnified Party will promptly provide; or

(iii)                               pay the amount of the indemnification claim or, if applicable, elect to assume the control of the Claim under Section 10.5(d).

(c)                                  Claims under Section 10.3.  Upon Seller’s receipt of an effective Claim Notice from Purchaser asserting a Liberty PSA Indemnity Claim, Seller shall diligently take all actions permitted and required under Section 14.3 of the Liberty PSA, and upon recovery from Liberty, shall remit payment to Purchaser in accordance with Section 10.3.  Seller will use its commercially reasonably efforts to avail Purchaser of the rights available to Seller (including, to the extent available under the Liberty PSA, seeking reimbursement for Third Party costs and attorneys’ fees and costs incurred in enforcing such rights) under the Liberty PSA with respect to the Liberty PSA Indemnity Claim, provided that (i) Purchaser will be obligated to pay all reasonable out-of-pocket Third Party costs incurred by Seller in carrying out such efforts and (ii) Seller shall not be responsible or liable for costs or fees (in each case) of Purchaser’s attorneys related to pursuing the Liberty PSA Indemnity Claim, except that Seller will bear the costs described in clauses (i) and (ii) immediately above if Seller is able to obtain reimbursement of such costs under the Liberty PSA.

(d)                                 Information, Expenses. Promptly after the Indemnified Party receives notice of a claim or legal action by a Third Party that may result in a loss for which indemnification may be sought from the Indemnifying Party under Section 10.2 (a “Claim”), the Indemnified Party shall deliver a Claim Notice to the Indemnifying Party.  If the Indemnifying Party or its counsel so requests, the Indemnified Party shall furnish the Indemnifying Party with copies of all pleadings and other information with respect to such Claim.  At the election of the Indemnifying Party made within sixty days after receipt of such notice, the Indemnified Party shall permit the Indemnifying Party to assume control of such Claim, including the determination of all appropriate actions, the negotiation of settlements on behalf of the Indemnified Party, and the conduct of litigation through attorneys of the Indemnifying Party’s choice; provided, however, that no such settlement can result in any liability or cost to the Indemnified Party for which it is entitled to be indemnified hereunder without its consent.  If the Indemnifying Party elects to assume control, (i) any expense incurred by the Indemnified Party thereafter for investigation or defense of the matter shall be borne by the Indemnified Party (except as set forth in the proviso immediately below), and (ii) the Indemnified Party shall give all reasonable

30

information and assistance, other than pecuniary, that the Indemnifying Party shall deem necessary to the proper defense of such Claim, legal action, or other matter.  In the absence of such an election, the Indemnified Party will use its best efforts to defend, at the Indemnifying Party’s expense, the Claim until the Indemnifying Party assumes such defense, and, if the Indemnifying Party fails to assume such defense within the time period provided above, settle the same in the Indemnified Party’s reasonable discretion at the Indemnifying Party’s expense with the Indemnifying Party’s consent which shall not be unreasonably withheld.  If the Indemnifying Party is entitled to, and does, assume the defense of any such Claim, the Indemnified Party shall have the right to employ separate counsel at its own expense and to participate in the defense thereof; provided, however, that notwithstanding the foregoing, the Indemnifying Party shall pay the reasonable attorneys’ fees of the Indemnified Party if the Indemnified Party’s counsel shall have advised the Indemnified Party that there is a conflict of interest that could make it inappropriate under applicable standards of professional conduct to have common counsel for the Indemnifying Party and the Indemnified Party (provided that the Indemnifying Party shall not be responsible for paying for more than one separate firm of attorneys and one local counsel to represent all of the Indemnified Parties subject to such Claim).

Section 10.6                             Reservation as to Non-Parties.  Nothing herein is intended to limit or otherwise waive any recourse Purchaser or Seller may have against any non-party for any obligations or liabilities that may be incurred with respect to the Assets

Section 10.7                             Reductions in Damages.  The amount of any Damages for which an Indemnified Party is entitled to indemnity under this ARTICLE 10, shall be reduced by the amount of insurance proceeds realized by the Indemnified Party or its Affiliates with respect to such Damages (net of any collection costs, and excluding the proceeds of any insurance policy issued or underwritten by the Indemnified Party or its insurance captive or other Affiliate), and by the amount of any net Tax benefit actually realized by Purchaser as a result of the events giving rise to the Damages in question.

ARTICLE 11
TAX MATTERS

Section 11.1                             Tax Filings.  From the Effective Time through the Closing Date, Seller shall be responsible for filing with the Taxing authorities the applicable Tax Returns for ad valorem, property, severance, production and similar Taxes relating to the Assets which are required to be filed on or before the Closing Date and paying the Taxes reflected on such Tax Returns as due and owing (provided that to the extent such Taxes relate to the periods from and after the Effective Time, as determined pursuant to Section 11.2, such payment shall be on behalf of Purchaser, and promptly following the Closing Date, Purchaser shall pay to Seller any such Taxes; but only to the extent that such amounts have not already been accounted for under Section 3.4).  Purchaser shall be responsible for the filing with the appropriate taxing authorities the applicable Tax Returns for all ad valorem, property, severance, production and similar Taxes that are required to be filed after the Closing Date and paying the Taxes reflected on such Tax Returns as due and owing; provided, however, that in the event that Seller is required by applicable Tax Law to file a Tax Return with respect to such Taxes after the Closing Date which includes all or a portion of a Tax period for which Purchaser is liable for such Taxes, following Seller’s request, Purchaser shall promptly pay to Seller all such Taxes allocable to the period or

31

portion thereof beginning at or after the Effective Time (but only to the extent that such amounts have not already been accounted for under Section 3.4), whether such Taxes arise out of the filing of an original return or a subsequent audit or assessment of Taxes; and provided further, if Purchaser is responsible hereunder for the filing of any Tax Returns which include Taxes for which Seller is responsible pursuant to Section 2.4(f), Section 10.1 or any other provision of this Agreement, on Purchaser’s request, Seller shall promptly pay to Purchaser all such Taxes allocable to the period or portion thereof prior to the Effective Time (but only to the extent that such amounts have not already been accounted for under Section 3.4), whether such Taxes arise out of the filing of an original return or a subsequent audit or assessment of Taxes.  Seller shall be entitled to all Tax credits and Tax refunds that relate to any such Taxes allocable to any Tax period, or portion thereof, ending before the Effective Time.

Section 11.2                             Current Tax Period Taxes.  Ad valorem, property, severance, production and similar Taxes assessed against the Assets with respect to the Tax period in which the Effective Time occurs (the “Current Tax Period”), but excluding ad valorem, property, severance production or similar Taxes that are based on quantity of or the value of production of Hydrocarbons, shall be apportioned between the Parties as of the Effective Time with (a) Seller being obligated to pay a proportionate share of the actual amount of such Taxes for the Current Tax Period determined by multiplying such actual Taxes by a fraction, the numerator of which is the number of days in the Current Tax Period prior to the Effective Time and the denominator of which is the total number of days in the Current Tax Period and (b) Purchaser being obligated to pay a proportionate share of the actual amount of such Taxes for the Current Tax Period determined by multiplying such actual Taxes by a fraction, the numerator of which is the number of days (including the Closing Date) in the Current Tax Period on and after the Effective Time and the denominator of which is the total number of days in the Current Tax Period.  As described in Section 2.4(f), ad valorem, property, severance, production and similar Taxes that are based on quantity of or the value of production of Hydrocarbons shall be apportioned between the Parties based on the number of units or value of production actually produced, as applicable, before, and at or after, the Effective Time.  In the event that Purchaser or Seller makes any payment for which it is entitled to reimbursement under this ARTICLE 11, the applicable Party shall make such reimbursement promptly but in no event later than ten days after the presentation of a statement setting forth the amount of reimbursement to which the presenting Party is entitled along with such supporting evidence as is reasonably necessary to calculate the amount of the reimbursement.

Section 11.3                             Characterization of Certain Payments.  The Parties agree that any payments made pursuant to this ARTICLE 11, ARTICLE 10, Section 2.4 and Section 8.4 shall be treated for all Tax purposes as an adjustment to the Unadjusted Purchase Price unless otherwise required by Law.

Section 11.4                             Other Tax Matters.  Purchaser and Seller, the extent each is legally permitted, agree to furnish or cause to be furnished to the other, upon request, as promptly as practicable, such information and assistance relating to the Assets, including access to books and records, as is reasonably necessary for the filing of all Tax Returns by Purchaser or Seller, the making of any election relating to Taxes, the preparation for any audit by any Taxing authority and the prosecution or defense of any claim, suit or proceeding relating to any Tax.  Each of Purchaser and Seller shall retain all books and records with respect to Taxes pertaining to the

32

Assets for a period of at least seven years following the Closing Date.  Purchaser and Seller shall reasonably cooperate with each other in the conduct of any audit, litigation or other proceeding relating to Taxes involving the Assets or the Purchase Price Allocation Schedule.  Seller shall promptly notify Purchaser in writing upon receipt by Seller of notice of any pending Tax audits or assessments relating to the income, properties or operations of Seller that reasonably may be expected to relate to or give rise to a Lien on the Assets.

(ii)                                  The arbitration shall be governed by Colorado Law but the specific procedure to be followed shall be determined by the arbitrator(s).  It is the intent of the Parties that the arbitration be conducted as efficiently and inexpensively as possible, with only limited discovery as determined by the arbitrator without regard to the discovery permitted under the Colorado or Federal Rules of Civil Procedure.

(iii)                               The arbitration proceeding shall be held in the City and County of Denver, Colorado, and a hearing shall be held no later than 60 days after submission of the matter to arbitration, and a written decision shall be rendered by the arbitrators within 30 days of the hearing.

(iv)                              At the hearing, the Parties shall present such evidence and witnesses as they may choose, with or without counsel.  Adherence to formal rules of evidence shall not be required but the arbitrator shall consider any evidence and testimony that he or she determines to be relevant, in accordance with procedures that it determines to be appropriate.

(v)                                 Any award entered in the arbitration shall be made by a written opinion stating the reasons and basis for the award made.

(vi)                              The costs incurred in employing the arbitrators, including the arbitrators’ retention of any independent qualified experts, shall be borne 50% by Seller and 50% by Purchaser.

(vii)                           The arbitrator’s award may be filed in any court of competent jurisdiction and may be enforced by any Party as a final judgment of such court.

(c)                                  Each of the Parties hereby irrevocably waives all right to trial by jury in any action, proceeding or counterclaim arising out of or relating to this Agreement.

Section 12.3                             Entire Agreement.  This Agreement (including, for purposes of certainty, the Appendix, Exhibits and Schedules attached hereto) and the documents to be executed hereunder constitute the entire agreement between the Parties pertaining to the subject matter hereof, and supersede all prior agreements, understandings, negotiations and discussions, whether oral or written, of the Parties pertaining to the subject matter hereof.

Section 12.4                             No Third Party Beneficiaries.  Except as provided in Section 10.2 (to the Persons described therein), nothing in this Agreement, express or implied, shall entitle any Person other than the Parties and their respective successors and permitted assigns to any claim, remedy or right of any kind under (or pursuant to) this Agreement.  Notwithstanding the foregoing, the Parties acknowledge and agree that only a Party or its successor or permitted assign, shall have the right to (it being understood and agreed that such Person shall not have the obligation to) enforce the provisions of (or exercise any right or remedy under) this Agreement on its own behalf or any of its related indemnified parties.

Section 12.5                             Limitation on Damages.  NOTWITHSTANDING ANYTHING TO THE CONTRARY, EXCEPT IN CONNECTION WITH ANY DAMAGES INCURRED BY THIRD PARTIES FOR WHICH INDEMNIFICATION IS SOUGHT UNDER THE TERMS OF THIS AGREEMENT, NONE OF PURCHASER, SELLER OR ANY OF THEIR RESPECTIVE AFFILIATES SHALL BE ENTITLED TO CONSEQUENTIAL, SPECIAL, INDIRECT, PUNITIVE OR EXEMPLARY DAMAGES IN CONNECTION WITH THIS AGREEMENT AND THE TRANSACTIONS CONTEMPLATED HEREBY AND, EXCEPT AS OTHERWISE PROVIDED IN THIS SENTENCE, EACH OF PURCHASER AND SELLER, FOR ITSELF AND ON BEHALF OF ITS AFFILIATES, HEREBY EXPRESSLY WAIVES ANY RIGHT TO CONSEQUENTIAL, SPECIAL, INDIRECT, PUNITIVE OR EXEMPLARY DAMAGES IN CONNECTION WITH THIS AGREEMENT AND THE TRANSACTIONS CONTEMPLATED HEREBY.

Section 12.7                             Specific Performance.  The Parties agree that if any of the provisions of this Agreement were not performed in accordance with their specific terms, irreparable damage would occur, no adequate remedy at Law would exist and damages would be difficult to determine, and the Parties shall be entitled to specific performance of the terms hereof and immediate injunctive relief, without the necessity of proving the inadequacy of money damages as a remedy, in addition to any other remedy available at law or in equity.

35

Section 12.8                             Severability.  The invalidity or unenforceability of any term or provision of this Agreement in any situation or jurisdiction shall not affect the validity or enforceability of the other terms or provisions hereof or the validity or enforceability of the offending term or provision in any other situation or in any other jurisdiction and the remaining terms and provisions shall remain in full force and effect, unless doing so would result in an interpretation of this Agreement that is manifestly unjust.

Section 12.9                             Financial Statements.  Seller acknowledges that Purchaser and its Affiliates may be required to include statements of revenues and direct operating expenses and other financial information relating to the transactions contemplated by this Agreement in documents filed by Purchaser and its Affiliates with the Securities Exchange Commission (the “SEC”) pursuant to the Securities Act of 1933, as amended, and the Securities Exchange Act of 1934, as amended, and that such financial statements may be required to be audited.  Accordingly, from and after the Execution Date, Seller shall use commercially reasonable efforts to (a) promptly provide Purchaser with such information about the Assets as may be required to be included in the documents filed by Purchaser and its Affiliates with the SEC, (b) provide, and shall cause its Affiliates, officers and employees to provide, reasonable cooperation in connection with the preparation of such documents, including providing reasonable access to auditors, auditor work papers, employees, books and records, and any financial data reasonably requested by Purchaser in connection therewith, and (c) cause its independent public accountants to provide any consent necessary for the filing of such documents and to deliver a customary comfort letter to Purchaser with respect to financial information relating to the transactions contemplated by this Agreement included as part of such documents.

(ii)                                  Within five Business Days of the receipt of the Demand Notice, Triangle shall give written notice of such Demand Notice to all Holders and, as soon as reasonably practicable thereafter, shall, subject to the limitations of this Section 2(a), file a Registration Statement covering all of the Registrable Securities that the Holders shall in writing request (such request to be given to Triangle within three days of receipt of such notice of the Demand Notice given by Triangle pursuant to this Section 2(a)(ii)) to be included in such Demand Registration as promptly as practicable as directed by the Initiating Holder in accordance with the terms and conditions of the Demand Notice and use all commercially reasonable efforts to cause such Registration Statement to become effective under the Securities Act and remain effective under the Securities Act until all Registrable Securities covered by such Registration Statement have been sold (the “Effectiveness Period”).

(iii)                               Subject to the other limitations contained in this Agreement, Triangle is not obligated hereunder to effect (A) more than one Demand Registration in any 12 month period, (B) more than a total of three Demand Registrations pursuant to this Agreement and (C) a subsequent Demand Registration pursuant to a Demand Notice if a Registration Statement covering all of the Registrable Securities held by the Holders providing such Demand Notice shall have become effective under the Securities Act and remains effective under the Securities Act and is sufficient to permit offers and sales of the number and type of Registrable Securities on the terms and conditions specified in the Demand Notice in accordance with the intended timing and method or methods of distribution thereof specified in the Demand Notice.

(iv)                              Notwithstanding any other provision of this Section 2(a), Triangle shall not be required to effect a registration or file a Registration Statement (or any amendment thereto) for a period of up to 60 days, if (A) the Board determines that a postponement is in the best interest of Triangle and its stockholders generally due to a pending transaction involving Triangle, (B) the Board determines such registration would render Triangle unable to comply with applicable securities laws or (C) the Board determines such registration would require disclosure of material information that

(v)                                 Triangle may include in any such Demand Registration other Triangle Securities for sale for its own account or for the account of any other Person; provided that if the managing underwriter, if any, for the Underwritten Offering determines that the type or number of Triangle Securities proposed to be offered in such offering would likely have an adverse effect in any material respect on the price, timing or distribution of the Registrable Securities proposed to be included in such offering, the Registrable Securities to be sold by the Holders shall be included in such registration before any Triangle Securities proposed to be sold for the account of Triangle or any other Person other than the NGP Holders.

(vi)                              Subject to the limitations contained in this Agreement, Triangle shall effect any Demand Registration on Form S-3 (except if Triangle is not then eligible to register for resale the Registrable Securities on Form S-3, in which case such Demand Registration shall be effected on another appropriate form for such purpose pursuant to the Securities Act) and if Triangle becomes, and is at the time of its receipt of a Demand Notice, a WKSI, the Demand Registration for any offering and selling of Registrable Securities shall be effected pursuant to an Automatic Shelf Registration Statement, which shall be on Form S-3 or any equivalent or successor form under the Securities Act (if available to Triangle); provided, however, that if at any time a Registration Statement on Form S-3 is effective and a Holder provides written notice to Triangle that it intends to effect an offering of all or part of the Registrable Securities included on such Registration Statement, Triangle will amend or supplement such Registration Statement as may be necessary in order to enable such offering to take place.

9

jurisdiction solely as a result of registration and (2) such forms, amendments, supplements, prospectuses, certificates, letters, opinions and other documents as may be necessary to apply for listing or to list the Registrable Securities subject to such Demand Registration on the Trading Market and (B) do any and all other acts and things that may be reasonably necessary or appropriate or reasonably requested by the Holders to enable the Holders to consummate a public sale of such Registrable Securities in accordance with the intended timing and method or methods of distribution thereof.

(ix)                              In the event a Holder transfers Registrable Securities included on a Registration Statement and such Registrable Securities remain Registrable Securities following such transfer, at the request of such Holder, Triangle shall amend or supplement such Registration Statement as may be necessary in order to enable such transferee to offer and sell such Registrable Securities pursuant to such Registration Statement; provided that in no event shall Triangle be required to file a post-effective amendment to the Registration Statement unless (A) such Registration Statement includes only Registrable Securities held by the Holder, Affiliates of the Holder or transferees of the Holder or (B) Triangle has received written consent therefor from whom Registrable Securities have been registered on (but not yet sold under) such Registration Statement, other than the Holder, Affiliates of the Holder or transferees of the Holder.

(x)                                 The rights of the Holders under this Section 2(a) shall terminate at such time that both (A) the number of Registrable Securities is less than 3% of the number of outstanding shares of Common Stock, and (B) such Registrable Securities may be sold or transferred by the Holder thereof under Rule 144 under the Securities Act without any limitation on the volume or timing.

(b)                                 Piggyback Registration.

(i)                                     If Triangle shall at any time propose to conduct, other than pursuant to any Demand Registration, a public offering of Common Stock for cash (whether in connection with a public offering of Common Stock by Triangle, a public offering of Common Stock by stockholders, or both, but excluding an offering relating solely to an employee benefit plan, an offering relating to a transaction on Form S-4 or S-8 or an offering on any registration statement form that does not permit secondary sales), Triangle shall promptly notify all Holders of such proposal reasonably in advance of (and in any event at least five Business Days before) the commencement of the offering (the “Piggyback Notice”).  The Piggyback Notice shall offer the Holders the opportunity to include for registration in such Registration Statement the number of Registrable Securities as they may request (a “Piggyback Registration”).  Triangle shall use commercially reasonable efforts to include in each such Piggyback Registration such Registrable Securities for which Triangle has received a written request from a Holder within three Business Days after delivery of the Piggyback Notice to such Holder (“Piggyback Request”) for inclusion therein.  If a Holder decides not to include all of its Registrable Securities in any Registration Statement thereafter filed by Triangle, such Holder shall nevertheless continue to have the right to include any Registrable Securities in any subsequent registration statement or registration statements as may be filed by

10

Triangle with respect to offerings of Common Stock, all upon the terms and conditions set forth herein.

(ii)                                  If the Registration Statement under which Triangle gives notice under this Section 2(b) is for an underwritten offering, Triangle shall so advise the Holders of Registrable Securities.  In such event, the right of any such Holder to be included in a registration pursuant to this Section 2(b) shall be conditioned upon such Holder’s participation in such underwriting and the inclusion of such Holder’s Registrable Securities in the underwriting to the extent provided herein.  All Holders proposing to distribute their Registrable Securities through such underwriting shall enter into an underwriting agreement in customary form with the underwriter or underwriters selected for such underwriting by Triangle.  If the managing underwriter or managing underwriters of such offering advise Triangle and the Holders in writing that in their reasonable opinion that the inclusion of all of the Holders’ Registrable Securities in the subject Registration Statement (or any other Common Stock proposed to be included in such offering) would likely have an adverse effect in any material respect on the price, timing or distribution of Common Stock proposed to be included in such offering, Triangle shall include in such offering only that number of shares of Common Stock proposed to be included in such offering that, in the reasonable opinion of the managing underwriter or managing underwriters, will not have such effect, with such number to be allocated as follows:

(A)       if such registration statement is filed other than pursuant to a demand registration initiated by the NGP Holders, (i) first, to Triangle, (ii) if there remains availability for additional shares of Common Stock to be included in such registration, second pro rata among the NGP Holders and all Holders desiring to register Registrable Securities based on the number of Registrable Securities held by all such Holders and the number of registrable securities held by the NGP Holders, and (iii) if there remains availability for additional shares of Common Stock to be included in such registration, third pro-rata among all other holders of Common Stock who may be seeking to register such Common Stock based on the number of shares of Common Stock such holder is entitled to include in such registration.

(B)       if such registration statement is filed pursuant to a demand registration initiated by the NGP Holders, (i) first, to the NGP Holders, (ii) if there remains availability for additional shares of Common Stock to be included in such registration, second pro rata to the Holders desiring to register Registrable Securities based on the number of Registrable Securities held by all such Holders, and (iii) if there remains availability for additional shares of Common Stock to be included in such registration, third pro-rata among all other holders of Common Stock who may be seeking to register such Common Stock based on the number of shares of Common Stock such holder is entitled to include in such registration.

If any Holder disapproves of the terms of any such underwriting, such Holder may elect to withdraw therefrom by written notice to Triangle and the managing underwriter(s) delivered on or prior to the time of the commencement of such offering.  Any Registrable

11

Securities withdrawn from such underwriting shall be excluded and withdrawn from the registration.

(iii)                               Triangle shall have the right to terminate or withdraw any registration initiated by it under this Section 2(b) at any time in its sole discretion whether or not any Holder has elected to include Registrable Securities in such Registration Statement.  The registration expenses of such withdrawn registration shall be borne by Triangle in accordance with Section 4 hereof.

(iv)                              The rights of the Holders under this Section 2(b) shall terminate if the number of Registrable Securities is less than 5% of the number of outstanding shares of Common Stock.

(i)                                     Triangle will cooperate with such Holders to facilitate the timely preparation and delivery of certificates representing Registrable Securities to be delivered to a transferee pursuant to a Registration Statement, which certificates shall be free of all restrictive legends indicating that the Registrable Securities are unregistered or unqualified for resale under the Securities Act, Exchange Act or other applicable securities laws, and to enable such Registrable Securities to be in such denominations and registered in such names as any such Holder may request in writing.  In connection therewith, if required by Triangle’s transfer agent, Triangle will promptly, after the Effective Date of the Registration Statement, cause an opinion of counsel as to the effectiveness of the Registration Statement to be delivered to and maintained with its transfer agent, together with any other authorizations, certificates and directions required by the transfer agent which authorize and direct the transfer agent to issue such Registrable Securities without any such legend upon sale by the Holder of such Registrable Securities under the Registration Statement.

(j)                                    Upon the occurrence of any event contemplated by Section 3(e)(v), subject to Section 2(a)(iv) and this Section 3(j), as promptly as reasonably practicable, Triangle will prepare a supplement or amendment, including a post-effective amendment, if required by applicable law, to the affected Registration Statement or a supplement to the related Prospectus or any document incorporated or deemed to be incorporated therein by reference, and file any other required document so that, as thereafter delivered, no Registration Statement nor any Prospectus will contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading.

14

(k)                                 Such Holders may distribute the Registrable Securities by means of an underwritten offering; provided that (i) in the case of a Demand Registration, (A) the Initiating Holder provides written notice to Triangle of its intention to distribute Registrable Securities by means of an underwritten offering, which for the avoidance of doubt may be made at a date later than the original Demand Notice (the “Underwritten Offering Notice” and such underwritten offering being referred to herein as an “Underwritten Offering”) and (B) Holders (including the Initiating Holder) having an aggregate value of at least $30 million based on the VWAP of such Registrable Securities as of the date of such Underwritten Offering Notice desire to participate in such Underwritten Offering and, in the case of a Piggyback Registration, the electing Holders must include their Registrable Securities in an underwritten offering if the Piggyback Notice so requires, (ii) the right of any Holder to include such Holder’s Registrable Securities in such registration shall be conditioned upon such Holder’s participation in such underwriting and the inclusion of such Holder’s Registrable Securities in the underwriting to the extent provided herein, (iii) the managing underwriter or managing underwriters thereof shall be designated by the Initiating Holder in the case of a Demand Registration (provided, however, that such designated managing underwriter or managing underwriters shall be reasonably acceptable to Triangle), by Triangle in the case of a registration initiated by Triangle or by such other holder in the case of a registration initiated by another holder, (iv) each Holder participating in such underwritten offering agrees to enter into an underwriting agreement in customary form and sell such Holder’s Registrable Securities on the basis provided in any underwriting arrangements approved by the Persons entitled to select the managing underwriter or managing underwriters hereunder and (v) each Holder participating in such underwritten offering completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents reasonably required under the terms of such underwriting arrangements.  Triangle hereby agrees with each Holder that, in connection with any Underwritten Offering in accordance with the terms hereof, it will negotiate in good faith and execute all indemnities, underwriting agreements and other documents reasonably required under the terms of such underwriting arrangements, including using all commercially reasonable efforts to procure customary legal opinions and auditor “comfort” letters.  Notwithstanding the foregoing, Triangle is not obligated to effect more than (A) one Underwritten Offering in any 12 month period and (B) a total of three Underwritten Offering pursuant to this Agreement.   If, in the case of an Underwritten Offering, the managing underwriter advises Triangle that the inclusion of all of the Holders’ Registrable Securities in the subject Underwritten Offering would likely have an adverse effect in any material respect on the price, timing or distribution of Registrable Securities proposed to be included in such Underwritten Offering, then Triangle shall so advise all Holders of Registrable Securities that would otherwise be underwritten pursuant hereto, and the number of shares of Common Stock that may be included in the Underwritten Offering shall be allocated:

(A)           in the case of a demand registration initiated by the NGP Holders, (i) first to the NGP Holders and (ii) second to the Holders on a pro rata basis based on the number of Registrable Securities held by all such Holders.

(B)           in the case of a Demand Registration, (i) first to the Holders on a pro rata basis based on the number of Registrable Securities held by all such Holders (including the Initiating Holders) and (ii) second to the NGP Holders.

15

Any Registrable Securities excluded or withdrawn from such Underwritten Offering shall be withdrawn from the Underwritten Offering.  In the event that the managing underwriter limits the number of Registrable Securities to be included in the Underwritten Offering pursuant to this Section 3(k) such that at least one-third of the aggregate Registrable Securities set forth in such Holders’ written requests pursuant to this Section 3(k) are included in the Underwritten Offering, such Underwritten Offering shall not be considered to be an Underwritten Offering for purposes of the limitations set forth in this Section 3(k).

(l)                                     In the event such Holders seek to complete an Underwritten Offering, for a reasonable period prior to the filing of any Registration Statement and throughout the Effectiveness Period, Triangle will make available upon reasonable notice at Triangle’s principal place of business or such other reasonable place for inspection during normal business hours by the managing underwriter or managing underwriters selected in accordance with Section 3(k) such financial and other information and books and records of Triangle, and cause the officers, employees, counsel and independent certified public accountants of Triangle to respond to such inquiries, as shall be reasonably necessary (and in the case of counsel, not violate an attorney-client privilege in such counsel’s reasonable belief) to conduct a reasonable investigation within the meaning of Section 11 of the Securities Act.

(m)                             In connection with any Demand Registration, Triangle will use commercially reasonable efforts to cause appropriate officers and employees to be available, on a customary basis and upon reasonable notice, to meet with prospective investors in presentations, meetings and road shows.

(n)                                 Triangle may require the Holder to furnish to Triangle any other information regarding the Holder and the distribution of such securities as Triangle reasonably determines is required to be included in any Registration Statement.

4.                                      Registration Expenses.  All Registration Expenses incident to the Parties’ performance of or compliance with their respective obligations under this Agreement or otherwise in connection with any Demand Registration or Piggyback Registration (in each case, excluding any Selling Expenses) shall be borne by Triangle, whether or not any Registrable Securities are sold pursuant to a Registration Statement.  “Registration Expenses” shall include, without limitation, (i) all registration and filing fees (including fees and expenses (A) with respect to filings required to be made with the Trading Market and (B) in compliance with applicable state securities or “Blue Sky” laws), (ii) printing expenses (including expenses of printing certificates for Triangle Securities and of printing prospectuses if the printing of prospectuses is reasonably requested by a Holder of Registrable Securities included in the Registration Statement), (iii) messenger, telephone and delivery expenses, (iv) fees and disbursements of counsel, auditors and accountants for Triangle, (v) Securities Act liability insurance, if Triangle so desires such insurance, (vi) fees and expenses of all other Persons retained by Triangle in connection with the consummation of the transactions contemplated by this Agreement and (vii) all expenses relating to marketing the sale of the Registrable Securities, including expenses related to conducting a “road show.”  In addition, Triangle shall be responsible for all of its expenses incurred in connection with the consummation of the transactions contemplated by this Agreement (including expenses payable to third parties and including all salaries and expenses of their officers and employees performing legal or

16

accounting duties), the expense of any annual audit and the fees and expenses incurred in connection with the listing of the Registrable Securities on the Trading Market.

5.                                      Indemnification.

(a)                                 Triangle shall indemnify and hold harmless each Holder, its Affiliates and each of their respective officers and directors and any Person who controls any such Holder (within the meaning of the Securities Act) and any agent thereof (collectively, “Holder Indemnified Persons”), to the fullest extent permitted by applicable law, from and against any and all losses, claims, damages, liabilities, joint or several, costs (including reasonable costs of preparation and reasonable attorneys’ fees) and expenses, judgments, fines, penalties, interest, settlements or other amounts arising from any and all claims, demands, actions, suits or proceedings, whether civil, criminal, administrative or investigative, in which any Indemnified Person may be involved, or is threatened to be involved, as a party or otherwise, under the Securities Act or otherwise (collectively, “Losses”), as incurred, arising out of or relating to any untrue or alleged untrue statement of a material fact contained in any Registration Statement under which any Registrable Securities were registered, in any preliminary prospectus (if Triangle authorized the use of such preliminary prospectus prior to the Effective Date), or in any summary or final prospectus or free writing prospectus (if such free writing prospectus was authorized for use by Triangle) or in any amendment or supplement thereto (if used during the period Triangle is required to keep the Registration Statement current), or arising out of, based upon or resulting from the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements made therein, in the light of the circumstances in which they were made, not misleading; provided, however, that Triangle shall not be liable to any Holder Indemnified Person to the extent that any such claim arises out of, is based upon or results from an untrue or alleged untrue statement or omission or alleged omission made in such Registration Statement, such preliminary, summary or final prospectus or free writing prospectus or such amendment or supplement, in reliance upon and in conformity with written information furnished to Triangle by or on behalf of such Holder Indemnified Person or any underwriter specifically for use in the preparation thereof.  Triangle shall notify the Holders promptly of the institution, threat or assertion of any Proceeding of which Triangle is aware in connection with the transactions contemplated by this Agreement.  Notwithstanding anything to the contrary herein, this Section 5 shall survive any termination or expiration of this Agreement indefinitely.

(b)                                 In connection with any Registration Statement in which a Holder participates, such Holder shall indemnify and hold harmless Triangle, its Affiliates and each of their respective officers, directors and any Person who controls Triangle (within the meaning of the Securities Act) and any agent thereof (collectively, the “Triangle Indemnified Persons”), to the fullest extent permitted by applicable law, from and against any and all Losses as incurred, arising out of or relating to any untrue or alleged untrue statement of a material fact contained in any such Registration Statement, in any preliminary prospectus (if used prior to the Effective Date of such Registration Statement), or in any summary or final prospectus or free writing prospectus or in any amendment or supplement thereto (if used during the period Triangle is required to keep the Registration Statement current), or arising out of, based upon or resulting from the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements made therein, in the light of the circumstances in which they

17

were made, not misleading, but only to the extent that the same are made in reliance and in conformity with information relating to the Holder furnished in writing to Triangle by such Holder for use therein.

(c)                                  Any Person entitled to indemnification hereunder shall (i) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification and (ii) unless in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist with respect to such claim or there may be reasonable defenses available to the indemnified party that are different from or additional to those available to the indemnifying party, permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party.  If such defense is assumed, the indemnifying party shall not be subject to any liability for any settlement made by the indemnified party without its consent (but such consent will not be unreasonably withheld).  An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim shall not be obligated to pay the fees and expenses of more than one counsel (in addition to any local counsel) for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified party there may be one or more legal or equitable defenses available to such indemnified party that are in addition to or may conflict with those available to another indemnified party with respect to such claim.  Failure to give prompt written notice shall not release the indemnifying party from its obligations hereunder.

6.                                      Facilitation of Sales Pursuant to Rule 144.  To the extent it shall be required to do so under the Exchange Act, Triangle shall timely file the reports required to be filed by it under the Exchange Act or the Securities Act (including the reports under Sections 13 and 15(d) of the Exchange Act referred to in subparagraph (c)(1) of Rule 144), and shall take such further action as any Holder may reasonably request, all to the extent required from time to time to enable the Holders to sell Registrable Securities without registration under the Securities Act within the limitations of the exemption provided by Rule 144.  Upon the request of any Holder in connection with that Holder’s sale pursuant to Rule 144, Triangle shall deliver to such Holder a written statement as to whether it has complied with such requirements.

7.                                      [Intentionally Omitted]

8.                                      Preemptive Rights.

(a)                                 Except in the case of Excluded Securities, Triangle shall not issue, exchange or otherwise Dispose, agree to issue, exchange or otherwise Dispose, or reserve or set aside for the same, any Equity Securities of Triangle or any securities convertible into or exchangeable for Equity Securities of Triangle (the “Offered Securities”), unless in each case Triangle shall have first given written notice to Purchaser (the “Preemptive Offer Notice”) at least 10 Business Days prior to entering into a definitive agreement for such sale stating that Triangle proposes to sell such Offered Securities, the number or amount of the Offered Securities proposed to be sold, the proposed purchase price or price range therefor and any other terms and conditions of such offer.

18

(b)                                 On or before the seventh Business Day following the date of the Preemptive Offer Notice (the “Preemptive Offer Period”), the Purchaser shall have the option to subscribe for up to its pro rata share of such Offered Securities (based on its percentage ownership of Common Stock calculated on a fully-diluted basis using the treasury stock method and assuming full conversion of any outstanding convertible notes of the Company) by delivering written notice to Triangle (a “Preemptive Offer Acceptance Notice”).  Notwithstanding the preceding sentence, the number of Offered Securities that the Purchaser is entitled to purchase shall not exceed an amount that would require Stockholder Approval under, or would result in a violation of, the rules and regulations of NYSE MKT or any other principal stock exchange or market upon which the Offered Securities trade; provided, however, that if the Purchaser cannot purchase at least 75% of the number of Offered Securities as to which a Preemptive Offer Acceptance Notice has been given by the Purchaser as a result of the limitations set forth in this sentence, then Triangle shall not issue, exchange or otherwise Dispose, agree to issue, exchange or otherwise Dispose, or reserve or set aside for the same all or any part of the Offered Securities without the prior written consent of the Purchaser.  Each Preemptive Offer Acceptance Notice shall specify:  (i) the amount of Offered Securities the Purchaser desires to subscribe for and (ii) the prices at which the Purchaser is willing to purchase such amounts of the Offered Securities at each such price.

(c)                                  Triangle shall have 30 days from the expiration of the Preemptive Offer Period to enter into a definitive agreement to issue and sell all or any part of such Offered Securities as to which a Preemptive Offer Acceptance Notice has not been given by the Purchaser (the “Refused Securities”) to any other Persons, but only upon terms and conditions in all material respects, including price, which are no more favorable, individually or in the aggregate, to such other Persons or less favorable, individually or in the aggregate, to Triangle than those set forth in the Preemptive Offer Notice. Upon the closing, which shall occur at a reasonable time and place within 60 days from the expiration of the Preemptive Offer Period (which such period shall be extended for up to 180 days with respect to any Person seeking to purchase Offered Securities, including the Purchaser, for such time as is necessary to allow such Person to request any approvals required under the HSR Act) and shall include full payment to Triangle of the proceeds from the sale to such other Persons of all the Refused Securities, the Purchaser shall purchase from Triangle, and Triangle shall sell to the Purchaser, the Offered Securities with respect to which a Preemptive Offer Acceptance Notice was delivered by the Purchaser, at the terms specified in the Preemptive Offer Notice. In each case, any Offered Securities not purchased by the Purchaser or any other Persons in accordance with this Section 8(c) within 60 days (or such longer period if the time period within which to close is extended as provided in the immediately preceding sentence) after the expiration of the Preemptive Offer Period may not be sold or otherwise Disposed of until they are again offered to the Purchaser under the procedures specified in this Section 8(c).

(d)                                 The rights of the Purchaser under this Section 8 shall terminate upon the occurrence of a Termination Event and shall not apply to the following securities (the “Excluded Securities”):

(i)                                     the issuance of any Equity Securities, or securities convertible into or exchangeable for Equity Securities, of Triangle pursuant to any employee benefits or other compensation plan approved by the Board and the Stockholders;

19

(ii)                                  Equity Securities, or securities convertible into or exchangeable for Equity Securities, of Triangle issued otherwise than for cash pursuant to, a merger, consolidation, acquisition, disposition or similar business combination approved by the Board;

(iii)                               Equity Securities, or securities convertible into or exchangeable for Equity Securities, of Triangle issued upon any stock dividend, stock split or other pro-rata distribution, subdivision or combination of securities or other recapitalization of Triangle;

(iv)                              Equity Securities issued upon conversion of the Convertible Note and other convertible notes issued concurrently herewith; and

(v)                                 Equity Securities, or securities convertible into or exchangeable for Equity Securities, of Triangle issued pursuant to the terms of a “poison pill” or other stockholder rights plan.

9.                                      Director Designation Rights.

(a)                                 Board Representation.

(i)                                     On the date on which the aggregate consideration paid by Purchaser and its Affiliates to Triangle for shares of Common Stock from Triangle exceeds $150 million, the Board shall adopt resolutions that (i) increase the number of natural persons that constitute the whole Board by one (1) person and (ii) fill the vacancy created by virtue of such increase in the size of the Board with an individual designated by the Purchaser, in each case pursuant to the Triangle Organizational Documents, who must in the reasonable judgment of Triangle, (A) qualify as an Independent Director, (B) have the requisite skill and experience to serve as a director of a publicly traded company, (C) not be prohibited or disqualified from serving as a director of Triangle pursuant to the Triangle Bylaws (as in effect as of the date hereof) or any rule or regulation of the Commission, NYSE MKT (or any other principal stock exchange or market upon which the Common Stock may trade) or by applicable law and (D) otherwise be reasonably acceptable to Triangle (the “Designated Director”). The Purchaser shall, and shall cause the Designated Director to, timely provide Triangle with accurate and complete information relating to the Purchaser and the Designated Director that may be required to be disclosed by Triangle under the Exchange Act. In addition, at Triangle’s request, the Purchaser shall cause the Designated Director to complete and execute Triangle’s standard director and officer questionnaire and provide such other information as Triangle may reasonably request prior to being admitted to the Board or standing for reelection at an annual meeting of Stockholders or at such other time as may be requested by Triangle.

(ii)                                  The Designated Director will hold office until his or her term expires and such Designated Director’s successor has been duly elected and qualified or until such Designated Director’s earlier death, resignation or removal.

20

(iii)                               In order to designate an individual for appointment to the Board, the Purchaser must submit to Triangle a written notice in accordance with the notice provisions set forth in Section 7.08 of the Purchase Agreement, which notice shall include (i) the name, age, business address and residence address of such designee, (ii) a current resume and curriculum vitae of such designee and (iii) a statement describing such designee’s qualifications.

(iv)                              Prior to a Termination Event:

(A)                               in connection with each annual meeting of Stockholders, and subject to the conditions of Section 9(a)(i) of this Agreement, Triangle shall nominate the Designated Director for reelection to the Board and shall take all reasonable and lawful actions necessary or advisable to cause the Board to recommend that the Stockholders vote “FOR” the election of the Designated Director;

(B)                               promptly following any annual meeting of Stockholders at which the Designated Director is not elected to the Board, and subject to the provisions of Section 9(a)(i) of this Agreement, the Board shall adopt resolutions that (1) increase the number of natural persons that constitute the whole Board by one (1) person and (2) fill the vacancy created by virtue of such increase in the size of the Board with the Designated Director; and if the Board is prevented by Section 3.1 of the Triangle Bylaws from complying with clause (1) of this Section 9(a)(iv)(B), the Board shall amend the Triangle Bylaws as necessary to permit the Board to comply with clause (1) of this Section 9(a)(iv)(B);

(C)                               any Designated Director may be removed pursuant to Section 3.6 of the Triangle Bylaws, and any vacancy created by such removal shall be filled by the Board with an individual designated by the Purchaser who, subject to the conditions of Section 9(a)(i) of this Agreement, shall become the Designated Director;

(D)                               upon written notice from Triangle to the Purchaser that a Resignation Event has occurred, which notice shall set forth in reasonable detail the facts and circumstances constituting the Resignation Event, the Purchaser will cause the Designated Director then serving as a member of the Board to resign as a member of the Board within two (2) Business Days of such written notice; and

(E)                                any vacancy caused by the death, disability or resignation of the Designated Director shall be filled by the Board with an individual designated by the Purchaser who, subject to the conditions of Section 9(a)(i) of this Agreement, shall become the Designated Director.

(v)                                 Any action by the Purchaser to designate or replace the Designated Director shall be evidenced in writing furnished to Triangle and shall be signed by or on behalf of the Purchaser.

21

(vi)                              Prior to designating a Designated Director, the Purchaser shall enter into a written agreement in a form reasonably satisfactory to Triangle with the Designated Director whereby such Designated Director agrees to resign as a member of the Board upon a Resignation Event, a Termination Event or at the Purchaser’s request, as applicable. The Purchaser acknowledges and agrees that such an agreement is in the best interest of Triangle and the Purchaser, and that Triangle shall be a third party beneficiary of the terms and conditions of such an agreement, and Triangle shall have the right to enforce such an agreement to the same extent as the parties thereto.

(vii)                           Triangle shall not take any action that would lessen, restrict, prevent or otherwise have an adverse effect upon the foregoing rights of the Purchaser to Board representation, including by nominating more directors for election to the Board than the number of directors constituting the full Board; provided, however, that Triangle shall not be prohibited from taking such action that the Board determines (i) may be necessary to (A) comply with any rule or regulation of the Commission or NYSE MKT (or any other principal stock exchange or market upon which the Common Stock may trade) or (B) comply with applicable law or (ii) is required to comply with the provisions of the Triangle Organizational Documents.

(b)                                 Termination of Director Designation Rights. Upon the occurrence of a Termination Event, the Purchaser’s right to designate, and Triangle’s obligation to nominate, the Designated Director shall automatically terminate, and the Purchaser shall cause the Designated Director then serving as a member of the Board, promptly upon (and in any event within two (2) Business Days following) receipt of a written request from Triangle, to resign as a member of the Board. In the event Triangle does not request that the Designated Director be caused to resign upon occurrence of a Termination Event, such Designated Director will no longer be considered a designee of the Purchaser and will be subject to election and reelection in accordance with the Triangle Bylaws. The Purchaser shall have the right at any time to cause the Designated Director to resign as a member of the Board and to waive its rights to designate a nominee for election to the Board.

(c)                                  Director Indemnification. At all times while the Designated Director is serving as a member of the Board, and following any such Designated Director’s death, resignation, removal or other cessation as a director in such former Designated Director’s capacity as a former director, each Designated Director shall be entitled to all rights to indemnification and exculpation as are then made available to any other member of the Board. As between Triangle, on the one hand, and the Purchaser and its Affiliates, on the other hand, Triangle shall, in all events, be the full indemnitor of first resort and shall not be entitled to any contribution, indemnification or other payment by or from any of the Purchaser or its Affiliates.

(d)                                 Corporate Opportunities. Triangle hereby renounces any interest or expectancy in any business opportunity in which Teachers Insurance and Annuity Association of America, a New York stock life insurance company, or Purchaser or any of their respective Affiliates or Portfolio Companies (including any officers or directors thereof) (the “TIAA Group”) participates or seeks to participate (each, a “Business Opportunity”) other than a Business Opportunity that is presented to a Designated Director in such Person’s capacity as a director of Triangle and with respect to which no other member of the TIAA Group (other than

22

the Designated Director) independently receives notice or otherwise identifies such Business Opportunity (each Business Opportunity that is so renounced, being referred to as a “Renounced Business Opportunity”). No member of the TIAA Group, including any Designated Director, shall have any obligation to communicate or offer any Renounced Business Opportunity to Triangle, and any member of the TIAA Group may pursue a Renounced Business Opportunity. Notwithstanding anything to the contrary in this Section 9(d), Triangle shall not be prohibited from pursuing any Business Opportunity with respect to which it has renounced any interest or expectancy as a result of this Section 9(d).

10.                               Approval Right.  So long as (a) 50% or more of the Common Stock purchased by the Purchaser pursuant to the Purchase Agreement is issued and outstanding and held by the Purchaser and (b) Purchaser owns at least 10% of the then issued and outstanding Common Stock, Triangle shall not, and shall cause its Subsidiaries not to, directly or indirectly, Incur any Indebtedness (other than pursuant to the Triangle Credit Agreement or the terms of the Notes); provided, however, that Triangle may Incur Indebtedness and any of its Subsidiaries may Incur Indebtedness if on the date thereof the Consolidated Leverage Ratio does not exceed 5.0 to 1.0 (provided that the Triangle Credit Agreement and Notes are excluded from such calculation).

11.                               Miscellaneous.

(a)                                 Remedies.  In the event of a breach by Triangle of any of its obligations under this Agreement, each Holder, in addition to being entitled to exercise all rights granted by law and under this Agreement, including recovery of damages, will be entitled to specific performance of its rights under this Agreement.  Triangle agrees that monetary damages would not provide adequate compensation for any losses incurred by reason of a breach by it of any of the provisions of this Agreement and further agrees that, in the event of any action for specific performance in respect of such breach, it shall waive the defense that a remedy at law would be adequate.

(b)                                 Discontinued Disposition.  Each Holder agrees that, upon receipt of a notice from Triangle of the occurrence of any event of the kind described in clauses (ii) through (v) of Section 3(e) (a “Suspension Notice”), such Holder will forthwith discontinue disposition of such Registrable Securities under the Registration Statement until such Holder’s receipt of the copies of the supplemental Prospectus or amended Registration Statement as contemplated by Section 3(j) or until it is advised in writing by Triangle that the use of the applicable Prospectus may be resumed, and, in either case, has received copies of any additional or supplemental filings that are incorporated or deemed to be incorporated by reference in such Prospectus or Registration Statement (a “Suspension Period”).  Triangle may provide appropriate stop orders to enforce the provisions of this Section 11(b).

(c)                                  Amendments and Waivers.  No provision of this Agreement may be waived or amended except in a written instrument signed by Triangle and Holders that hold a majority of the Registrable Securities as of the date of such waiver or amendment.  Triangle shall provide prior notice to all Holders of any proposed waiver or amendment.  No waiver of any default with respect to any provision, condition or requirement of this Agreement shall be deemed to be a continuing waiver in the future or a waiver of any subsequent default or a waiver

23

of any other provision, condition or requirement hereof, nor shall any delay or omission of any Party to exercise any right hereunder in any manner impair the exercise of any such right.

(d)                                 Notices.  Any and all notices or other communications or deliveries required or permitted to be provided hereunder shall be in writing and shall be deemed given and effective on the earliest of (i) the date of transmission, if such notice or communication is delivered via facsimile or electronic mail as specified in this Section 11(d) prior to 5:00 p.m. (Denver Time) on a Business Day, (ii) the Business Day after the date of transmission, if such notice or communication is delivered via facsimile or electronic mail as specified in this Agreement later than 5:00 p.m. (Denver Time) on any date and earlier than 11:59 p.m. (Denver Time) on such date, (iii) the Business Day following the date of mailing, if sent by nationally recognized overnight courier service or (iv) upon actual receipt by the Party to whom such notice is required to be given.  The address for such notices and communications shall be as follows:

24

(e)                                  Successors and Assigns.  This Agreement shall be binding upon and inure to the benefit of the Parties hereto and their heirs, executors, administrators, successors, legal representatives and permitted assigns.  Except as provided in this Section 11(e), this Agreement, and any rights or obligations hereunder, may not be assigned without the prior written consent of Triangle and the Purchaser.  Notwithstanding anything in the foregoing to the contrary, (i) the registration rights of a Holder pursuant to this Agreement with respect to all or any portion of its Registrable Securities may be assigned without such consent (but only with all related obligations) with respect to such Registrable Securities (and any Registrable Securities issued as a dividend or other distribution with respect to, in exchange for or in replacement of such Registrable Securities) by such Holder to a transferee of such Registrable Securities; provided (A) Triangle is, within a reasonable time after such transfer, furnished with written notice of the name and address of such transferee or assignee and the Registrable Securities with respect to which such registration rights are being assigned and (B) such transferee or assignee agrees in writing to be bound by and subject to the terms set forth in this Agreement, and (ii) the rights of the Purchaser under Section 8 may be transferred or assigned in whole or in part by the Purchaser to an Affiliate of the Purchaser provided that (1) Triangle is, within a reasonable time after such transfer, furnished with written notice of the name and address of such Affiliate and (B) such Affiliate agrees in writing to be bound by and subject to the terms set forth in this Agreement.  Triangle may not assign its respective rights or obligations hereunder without the prior written consent of the Purchaser.
