From and after the Closing with respect to each Non-Transferred Excluded Asset, Laredo shall cause the Company to permit Contributors to exclusively direct and manage the Company’s participation in (and Laredo shall grant to Contributors or Contributors’ designee a power of attorney granting Contributors or such designee a full power of attorney with respect to) all negotiations, arbitrations, litigation, claims, and/or bankruptcy or other proceedings involving such Non-Transferred Excluded Asset, whether existing at the Closing or arising thereafter. Laredo shall also permit Contributors to settle or compromise on behalf of the Company any Non-Transferred Excluded Asset in Contributors’ sole discretion, and shall promptly pay to Contributors any proceeds or recoveries received in connection with any Non-Transferred Excluded Asset.

Section 11.06 Employee Matters.

(a) For a period of one year after the Closing Date (the “Continuation Period”), Laredo shall, or shall cause the Company to, provide the Company Employees who remain employed by the Company, or who become employed by Laredo or its Affiliate, following the Closing Date (the “Continuing Employees”) with compensation and benefits substantially comparable in the aggregate (without regard to equity-based compensation) to their compensation and benefits (without regard to equity-based compensation) with the Company immediately prior to the Closing Date; provided, however, that Laredo reserves the right to amend, terminate, merge or suspend any Company Employee Plan or Laredo Employee Plan in its sole discretion.

(b) Nothing contained in this Agreement is intended to confer upon (i) any Continuing Employee or (ii) any Company Employee any right to continued employment by Laredo, LPI or the Company, as applicable, at any time after the Closing Date.

(c) Notwithstanding anything to the contrary in this Agreement, the individuals listed on Schedule 11.06(c) will not become Continuing Employees and their employment with the Company shall be terminated via their resignations without any severance on the Closing Date.

ARTICLE XII
TERMINATION

Section 12.01 Right of Termination. This Agreement and the transactions contemplated hereby may be completely terminated at any time at or prior to the Closing:

(a) by mutual written consent of the Parties;

(b) by the Company, Contributor Representative or Laredo, by written notice to the other, if the Closing shall not have occurred on or before July 1, 2011; provided, however, that (i) neither Party can so terminate this Agreement if such Party is at such time in intentional and knowing breach of any material provision of this Agreement that is within such Party’s reasonable control; and (ii) such date shall be extended to the extent necessary to permit the cure of a Title Defect or Environmental Defect pursuant to Section 4.03(a) or Section 5.04(a), as applicable, to up to August 1, 2011;

(c) by the Company, Contributor Representative or Laredo, by written notice to the other, if the sum of the Company Title Defect Amount and the Company Environmental Defect Amount as properly submitted to the Company in accordance with Articles IV and V, respectively, exceeds the Aggregate Defect Threshold; provided that the termination right under this Section 12.01(c) shall not be applicable if the other Party exercised its right to cure a Title Defect or Environmental Defect with respect to the Company Properties pursuant to Section 4.03(a) or Section 5.04(a), as applicable, such Title Defect or Environmental Defect is so cured on or prior to August 1, 2011 and such cure results in the sum of the Title Defects and Environmental Defects with respect to the Company Properties not exceeding the Aggregate Defect Threshold;

(d) by the Company, Contributor Representative or Laredo, if the sum of all Laredo Title Defect Amounts and all Laredo Environmental Defect Amounts, as properly submitted to Laredo in accordance with Articles IV and V, respectively, exceeds the Aggregate Defect Threshold; provided that the termination right under this Section 12.01(d) shall not be applicable if Laredo exercised its right to cure a Title Defect or Environmental Defect with respect to the Laredo Properties pursuant to Section 4.03(a) or Section 5.04(a), as applicable, such Title Defect or Environmental Defect is so cured on or prior to August 1, 2011 and such cure results in the sum of the Title Defects and Environmental Defects with respect to the Laredo Properties not exceeding the Aggregate Defect Threshold; or

(e) by the Company, Contributor Representative or Laredo, pursuant to Section 7.08(b).

Section 12.02 Effect of Termination. In the event that the Closing does not occur as a result of a Party exercising its right to terminate pursuant to Section 12.01, then, except for the provisions of Section 1.01, Section 1.02, this Section 12.02, Section 13.03, Section 13.06, Section 14.01 and Article XV (other than Section 15.01 and Section 15.02), this Agreement shall thereafter be null and void and no Party shall have any rights or obligations under this Agreement, except that nothing herein shall relieve any Party from Liability for any knowing and intentional breach of its material covenants or agreements hereunder. In the event of a termination of this Agreement as a result of a knowing and intentional breach by Laredo that is within Laredo’s reasonable control, in addition to other remedies available to Contributors at law or in equity, Laredo shall be liable to the Company and Contributors for all expenses incurred by such parties in connection with pursuing the transactions contemplated by this Agreement. In the event of a termination of this Agreement as a result of a knowing and intentional breach by a Contributor or the Company that is in the Contributor’s or the Company’s reasonable control, as applicable, in addition to other remedies available to Laredo at law or in equity, the Company and Contributors shall be liable to Laredo for all expenses incurred by Laredo in connection with pursuing the transactions contemplated by this Agreement. NOTWITHSTANDING ANYTHING TO THE CONTRARY IN THIS AGREEMENT, IN NO EVENT SHALL EITHER PARTY BE ENTITLED TO RECEIVE ANY SPECIAL, PUNITIVE OR EXEMPLARY DAMAGES, WHETHER BASED ON CONTRACT, TORT, STRICT LIABILITY, OTHER LAW OR OTHERWISE AND WHETHER OR NOT ARISING FROM THE OTHER PARTY’S SOLE, JOINT OR CONCURRENT NEGLIGENCE, STRICT LIABILITY OR OTHER FAULT, EXCEPT SUCH DAMAGES THAT ARE PAYABLE TO A THIRD PARTY WITH RESPECT TO A THIRD PARTY CLAIM FOR WHICH ANY PERSON IS SEEKING INDEMNIFICATION HEREUNDER.

ARTICLE XIII
INDEMNIFICATION

Section 13.01 Indemnification by Contributors and Laredo. Subject to the other provisions of Article XIII, from and after Closing:

(a) each Contributor severally and not jointly will defend, release, indemnify and hold harmless each of the Laredo Indemnitees (including, from and after the Closing, the Company and its officers, directors and/or managers, employees, agents and representatives) from and against any and all Liabilities caused by, arising from or attributable to (i) the breach by such Contributor of its representations or warranties contained in Section 6.01(g) as of the date of this Agreement and as of the Closing, as though made at and as of the Closing and (ii) the breach by the Company of its representations or warranties contained in Section 6.02(g) as of the date of this Agreement and as of the Closing, as though made at and as of the Closing; and

(b) Laredo will defend, release, indemnify and hold harmless each of the Contributors and Company Indemnitees from and against any and all Liabilities caused by, arising from or attributable to the breach by Laredo of its representations or warranties contained in Section 6.03(d) and Section 6.03(h) as of the date of this Agreement and as of the Closing, as though made at and as of the Closing.

Section 13.02 Limitations. Contributors shall not incur, and shall have no obligation to Laredo Indemnitees under this Agreement or in connection with the transactions contemplated hereby with respect to, any Liability unless written notice of such Liability is provided to Warburg and the Contributor Representative within 12 months after Closing. Further, each Contributor’s Liability with regard to its, his or her indemnification obligation under Section 13.01(b) shall be limited to such Contributor’s pro rata share of such Liability determined by taking the amount of the obligation under such section and multiplying it by a percentage determined by dividing the amount of Equity Consideration received by such Contributor under this Agreement by the aggregate amount of Equity Consideration received by all Contributors under this Agreement. Laredo shall not incur, and shall have no obligation to Company Indemnitees under this Agreement or in connection with the transactions contemplated hereby with respect to, any Liability unless written notice of such Liability is provided to Laredo within 12 months after Closing.

Section 13.03 Remedies. Notwithstanding anything to the contrary in this Agreement, (a) Laredo shall be entitled to all remedies at law or in equity against any Contributor for such Contributor’s breach of the representations and warranties contained in Sections 6.01(g) and 6.02(g) and (b) Contributors and the Company shall be entitled to all remedies at law or in equity against Laredo for its breach of the representations and warranties contained in Section 6.03(d) and Section 6.03(h).

Section 13.04 Negligence and Fault. THE DEFENSE, RELEASE, INDEMNIFICATION AND HOLD HARMLESS OBLIGATIONS SET FORTH IN THIS AGREEMENT (INCLUDING SECTION 13.01) SHALL ENTITLE THE INDEMNITEE TO SUCH DEFENSE, RELEASE, INDEMNIFICATION AND HOLD HARMLESS HEREUNDER IN ACCORDANCE WITH THE TERMS HEREOF, REGARDLESS OF WHETHER THE CLAIM GIVING RISE TO SUCH OBLIGATION IS THE RESULT OF: (A) STRICT LIABILITY, (B) THE VIOLATION OF ANY LAW BY SUCH INDEMNITEE OR BREACH OF DUTY (STATUTORY OR OTHERWISE), (C) THE SOLE, CONCURRENT OR COMPARATIVE NEGLIGENCE OF SUCH INDEMNITEE, OR (D) OTHER FAULT OF SUCH INDEMNITEE.

Section 13.05 Exclusive Remedy. Except to the extent expressly set forth in any Transaction Document (other than this Agreement) delivered herewith, from and after Closing, each of the Parties acknowledges and agrees that its sole and exclusive remedy with respect to any and all Liabilities pursuant to or in connection with this Agreement, the contribution of the Contributed Company Stock by Contributors in exchange for the Equity Consideration or otherwise in connection with the transactions contemplated hereby shall be limited to the indemnification provisions set forth in this Agreement.

Section 13.06 Expenses. Notwithstanding anything herein to the contrary, the foregoing defense, release, indemnity and hold harmless obligations shall not apply to, and, except as otherwise set forth in Section 12.02, each of Laredo and the Company shall be solely responsible for, all expenses, including due diligence expenses, incurred by it to enter into, and consummate the transactions contemplated by, this Agreement and the Purchase and Sale Agreement; the Parties understand and agree that the expenses of Thompson & Knight LLP, who has been engaged by the Company to negotiate this Agreement and the Purchase and Sale Agreement, and the transactions contemplated therein, shall be the expenses of the Company.

Section 13.07 Survival.

(a) The representations and warranties of Contributors in Sections 6.01(g) and 6.02(g) and Laredo in Sections 6.03(d) and 6.03(h) shall survive the Closing for a period of 12 months. All other representations and warranties contained herein and in any certificate or other writing delivered pursuant hereto shall not survive the Closing. This Section 13.07(a) shall not limit any covenant or agreement of the parties to this Agreement which, by its terms, contemplates performance after the Closing Date.

(b) The indemnities in Section 13.01 shall terminate as of the termination date of each respective representation, warranty, covenant or agreement that is subject to indemnification, except in each case as to matters for which a specific written claim for indemnity has been delivered to Contributors or Laredo, as applicable, on or before such termination date.

Section 13.08 Indemnification Actions. All claims for indemnification under this Article XIII shall be asserted and resolved as follows:

(a) For purposes of this Agreement, the term “Indemnitor” when used in connection with particular damages shall mean the Person having an obligation to indemnify another Person or Persons with respect to such damages pursuant to this Agreement, and the term “Indemnitee” when used in connection with particular damages shall mean a Person having the right to be indemnified with respect to such damages pursuant to this Agreement.

(b) To make a claim for indemnification under this Article XIII, an Indemnitee shall notify the Indemnitor of its claim, including the specific details of and specific basis under this Agreement for its claim (the “Claim Notice”). In the event that the claim for indemnification is based upon a claim by a Third Party against the Indemnitee (a “Claim”), the Indemnitee shall provide its Claim Notice promptly after the Indemnitee has actual knowledge of the Claim and shall enclose a copy of all papers (if any) served with respect to the Claim; provided that the failure of any Indemnitee to give notice of a Claim as provided in this Section 13.08 shall not relieve the Indemnitor of its obligations under this Article XIII except to the extent (and only to the extent of such incremental damages incurred) such failure results in insufficient time being available to permit the Indemnitor to effectively defend against the Claim or otherwise prejudices the Indemnitor’s ability to defend against the Claim. In the event that the claim for indemnification is based upon an inaccuracy or breach of a representation, warranty, covenant or agreement, the Claim Notice shall specify the representation, warranty, covenant or agreement that was inaccurate or breached.

(c) In the case of a claim for indemnification based upon a Claim, the Indemnitor shall have 30 days from its receipt of the Claim Notice to notify the Indemnitee whether or not it agrees to indemnify and defend the Indemnitee against such Claim under this Article XIII. The Indemnitee is authorized, prior to and during such 30 day period, to file any motion, answer or other pleading that it shall deem necessary or appropriate to protect its interests or those of the Indemnitor and that is not prejudicial to the Indemnitor.

(d) If the Indemnitor agrees to indemnify the Indemnitee, it shall have the right and obligation to diligently defend, at its sole cost and expense, the Claim. The Indemnitor shall have full control of such defense and proceedings, including any compromise or settlement thereof. If requested by the Indemnitor, the Indemnitee agrees to cooperate in contesting any Claim which the Indemnitor elects to contest (provided, however, that the Indemnitee shall not be required to bring any counterclaim or cross-complaint against any Person). The Indemnitee may participate in, but not control, at its sole cost and expense, any defense or settlement of any Claim controlled by the Indemnitor pursuant to this Section 13.08. An Indemnitor shall not, without the written consent of the Indemnitee, in the Indemnitee’s sole discretion, settle any Claim or consent to the entry of any judgment with respect thereto that (i) does not result in a final resolution of the Indemnitee’s Liability with respect to the Claim (including, in the case of a settlement, an unconditional written release of the Indemnitee from all Liabilities in respect of such Claim), (ii) may materially and adversely affect the Indemnitee (other than as a result of money damages covered by the indemnity) or (iii) includes any non-monetary remedy.

(e) If the Indemnitor does not agree to indemnify the Indemnitee within the 30 day period specified in Section 13.08(c) or fails to give notice to the Indemnitee within such 30 day period regarding its election or if the Indemnitor agrees to indemnify, but fails to diligently defend or settle the Claim, then the Indemnitee shall have the right to defend against the Claim (at the sole cost and expense of the Indemnitor, if the Indemnitee is entitled to indemnification hereunder), with counsel of the Indemnitee’s choosing; provided, however, that the Indemnitee shall make no settlement, compromise, admission or acknowledgment that would give rise to Liability on the part of any Indemnitor without the prior written consent of such Indemnitor, which consent shall not be unreasonably withheld, conditioned or delayed.

(f) In the case of a claim for indemnification not based upon a Claim, the Indemnitor shall have 30 days from its receipt of the Claim Notice to (i) cure the damages complained of, (ii) agree to indemnify the Indemnitee for such Liabilities, or (iii) dispute the claim for such damages. If such Indemnitor does not respond to such Claim Notice within such 30 day period, such Indemnitor will be deemed to dispute the claim for damages.

Section 13.09 Release. As of Closing, each Contributor for itself and its successors and assigns unconditionally and irrevocably fully and forever releases and discharges the Company and Laredo and each of their respective officers, directors, successors, assigns, parents and Affiliates from any and all claims, remedies, suits, damages and liabilities of any kind arising out of or relating in any respect to such Contributor’s ownership of any debt, equity or other interest in the Company prior to the Closing Date.

Subject to Section 7.08(b), Section 10.01 and this Section 15.03, no supplement, amendment, alteration, modification, waiver or termination of this Agreement shall be binding unless executed in writing by the Parties to be bound and specifically referencing this Agreement as being supplemented, amended, altered, modified, waived or terminated. The Parties acknowledge and agree that additional Stockholders and Optionholders may subsequently execute and deliver additional signature pages to this Agreement and become Parties hereto as Contributors under this Agreement at the time of such delivery, and notwithstanding such additional signatories and Parties, each Party executing this Agreement shall be bound by the terms and provisions of this Agreement from and after its execution and delivery of its signature page hereto until this Agreement is terminated in accordance with the terms hereof.

Employee-Contributor agrees not to assert any claim or file or permit to be filed or accept benefit from any claim, complaint or petition relating to Employee-Contributor’s Released Claims, and agrees to indemnify, defend and hold harmless the Company Released Parties from any Liabilities arising from any claim, complaint or petition that is in violation of this sentence; provided, however, this shall not limit Employee-Contributor from filing an action for the sole purpose of enforcing its rights under this Release. THE RELEASES APPLY TO ALL CLAIMS, AND EMPLOYEE-CONTRIBUTOR AGREES TO WAIVE THE BENEFITS OF ANY LAW (INCLUDING PRINCIPLES OF COMMON LAW) OF ANY STATE OR TERRITORY OR ANY OTHER JURISDICTION THAT PROVIDES THAT A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE RELEASING PARTY DOES NOT KNOW OR SUSPECT TO EXIST IN SUCH PARTY’S FAVOR AT THE TIME OF EXECUTING THE RELEASE, WHICH IF KNOWN BY SUCH PARTY MUST HAVE MATERIALLY AFFECTED HIS/HER SETTLEMENT WITH THE RELEASED PARTY.
