Failure of the Sellers to notify the Buyer within said 10-day time period shall constitute acceptance by Sellers of the Buyer's Report. (B) Upon receipt of a timely Disagreement Notice from the Sellers, Buyer and Sellers shall attempt in good faith to resolve any disagreements with respect to discrepancies between the NS Reports and the Buyer's Report. If, after ten (10) business days, the Buyer and the Sellers have not satisfactorily resolved any disagreements, then Rex Energy and the Buyer shall use their best efforts to select a third independent engineering firm to review the NS Report, using the same parameters set forth above. If, by that date that is fifteen (15) business days following the date that Buyer and Sellers commenced to resolve their disagreements regarding the NS Reports and the Buyer's Report, Rex Energy and the Buyer shall not have selected such a third independent engineering firm, then Netherland, Sewell & Associates and the Ralph E. Davis firm shall mutually select a third independent engineering firm to review the NS Report, applying the same parameters set forth above. The report of this third independent engineering firm shall be binding on the Buyer and the Sellers. (C) If Buyer shall have timely delivered a Buyer's Report to Sellers, then, in the event (i) Sellers agree with the Buyer's Report, (ii) fail to deliver a timely Disagreement Notice to Buyer or (iii) the report of the third independent engineering firm indicates an amount of total oil and natural gas reserves that is lower than the amount of reserves reflected in the NS Report as of June 1, 2005 (converting in each case all volumes of natural gas to Boe's) and such discrepancy is in excess of 10%, then the cash portion of the Purchase Price shall be reduced by $3,658,500 (unless this Agreement is terminated pursuant to sub-paragraph (D) below). (D) If such discrepancy is greater than 15%, then Buyer shall have the right to terminate this Agreement by giving written notice to the other within ten days after occurrence of the event described in clause (i) or (ii) of sub-paragraph 2(f)(i)(C) above or receipt of the report of the third engineering firm referred to in clause (iii) of sub-paragraph 2(f)(i)(C) above. (E) The Parties each acknowledge that the NS Reports reflect oil and gas reserves for properties of Penn-Tex Resources located outside of the States of Illinois and Indiana (the "Non-Illinois and Indiana Properties") and that the Non-Illinois and Indiana Properties were sold and transferred by PennTex Resources to a third party in October 2005. The parties acknowledge that the Acquired Assets to be purchased by the Buyer from PennTex Resources consists of Oil and Gas Assets located in the states of Illinois and Indiana and that there will be no adjustment to the Purchase Price for discrepancies in the NS Reports resulting from the sale of the Non-Illinois and Indiana Properties. 12 (ii) Within sixty (60) days after the Closing, Sellers and Buyer shall effect a post-closing accounting pursuant to which Buyer will account to Sellers for and pay over or assign and transfer (or cause Rex Energy or PennTex Illinois to pay over or assign or transfer) to Sellers (other than Rex Energy or PennTex Illinois, and as Sellers may direct): (A) any Cash of any of Sellers in existence at the Effective Time that is in the possession of Buyer (or of Rex Energy or PennTex Illinois); (B) all deposits, checks, funds, and accounts receivable of Sellers included in the Excluded Assets and any proceeds of collection thereof received by or in the possession of Buyer (or received by or in the possession of Rex Energy or PennTex Illinois); (C) all proceeds of sale and accounts receivable for sale of oil, gas and other hydrocarbons produced from or attributable to the Oil and Gas Assets prior to the Effective Time (including, without limitation, all such substances in storage, within processing plants, in pipelines or otherwise held in inventory at the Effective Time) that are included in the Excluded Assets and that have been received or are held by Buyer (or by Rex Energy or PennTex Illinois); and (D) any other Excluded Assets held by or in the possession or control of Buyer (or of Rex Energy or PennTex Illinois); and pursuant to which: (E) Sellers (other than Rex Energy or PennTex Illinois) shall reimburse Buyer (or Rex Energy or PennTex Illinois) for any costs or expenses (excluding any Assumed Liabilities) incurred by Rex Energy or PennTex Illinois or any of the other Sellers in the Ordinary Course of Business prior to the Effective Time that have been paid by Buyer or by Rex Energy or PennTex Illinois after the Effective Time, and Sellers (other than Rex Energy and PennTex Illinois) shall assume liability for any unpaid costs or expenses (excluding any Assumed Liabilities) incurred by Rex Energy or PennTex Illinois in the Ordinary Course of Business prior to the Effective Time; and (F) Buyer shall reimburse Sellers (other than Rex Energy or PennTex Illinois, and as Sellers may direct) for any Assumed Liabilities (including, without limitation, costs or expenses, including prepaid costs or expenses, arising out of or attributable to the ownership, use, construction, maintenance or operation of the Oil and Gas Assets on or subsequent to the Effective Time) that have been paid by Sellers (other than Rex Energy or PennTex Illinois). The post-closing accounting will not, of course, relieve the respective Sellers other than Rex Energy or PennTex Illinois from liability and responsibility for their unpaid obligations incurred prior to the Effective Time that are not included in the Assumed Liabilities and will not relieve Buyer from liability and responsibility for unpaid Assumed Liabilities. Within forty-five (45) days after the Closing Date, Buyer and Rex Energy and PennTex Illinois shall provide the other Sellers with all information in their possession relating to items to be dealt with in the post-closing accounting, and the Sellers other than Rex Energy and PennTex Illinois shall provide to Buyer all information in their possession relating to items to be dealt with in the 13 post-closing accounting; and the post-closing accounting shall be effected at 9:00 am in the offices of Sellers described in Section 2(c) on the sixtieth day following the Closing Date (or on the next succeeding business day if such day is a Saturday, Sunday or holiday), or at such other place, date or time as Sellers (other than Rex Energy and PennTex Illinois) and Buyer shall agree.

All shares of Buyer Common Stock subject to issuance as aforesaid, have been duly authorized and reserved, and upon their issuance on the terms and conditions specified in the instruments pursuant to which they are issuable, shall be validly issued, fully paid and non-assessable.

The Buyer does not have outstanding any bonds, debentures, notes or other obligations the holders of which have the right to vote (or convertible into or exercisable for securities having the right to vote) with its shareholders on any matter. Schedule 4(g) of the Buyer's Disclosure Schedule contains a schedule that specifies, on a fully-diluted basis as of the Closing Date, all of the issued and outstanding Buyer capital stock and all shares of Buyer Common Stock and all other capital stock issued, outstanding or then-issuable under Buyer Stock Options, the Convertible Notes, all outstanding warrants, or any other plans or commitments that Buyer will have outstanding as of the Closing Date, and the respective owners thereof; provided that shares of Buyer Common Stock, warrants issued to the placement agent of the Private Offering and/or Buyer Debt Securities (resulting, collectively, in the issuance or provision for issuance of not more than a total of 11,000,000 shares of Buyer Common Stock on a fully diluted basis) may have been issued in the Private Placement as described in Section 2(d) and except for Buyer Securities to be issued in the Closing Placements referred to in Section 5(k) hereof, all of which Buyer Common Stock shall have been issued and granted in compliance with all applicable federal, state and foreign securities laws and other applicable laws and regulations and shall be validly issued, fully paid and non-assessable. 24 (ii) All shares of Buyer Common Stock to be issued or transferred by the Buyer under the Stock Agreement shall be, upon their issuance or transfer, duly authorized, validly issued, fully paid and non-assessable.

(iv) All offers and sales of Buyer Common Stock and other securities of the Buyer (including the Convertible Notes and the Buyer Stock Options) made by the Buyer and its Affiliates have been made in compliance with the Securities Act, the Exchange Act, all applicable state securities or "Blue Sky" laws, and, where applicable, the laws or regulations of foreign jurisdictions. All offers and sales of Buyer Common Stock and other securities of the Buyer (including Buyer Stock Options) have not been required to have been registered or qualified under the Securities Act or the Exchange Act, and have been registered under all applicable state securities or "Blue Sky" laws or the laws or regulations of any foreign jurisdictions, and each such offer and sale has qualified for a valid exemption from registration or qualification under such laws and regulations, including any rules, regulations or interpretations requiring offers and sales of securities otherwise exempt from registration to be "integrated" as one offering and thereby require registration or qualification thereunder. The offers and sales of Buyer Common Stock (including Buyer Stock Options) contemplated to be made by the Buyer under this Agreement and the Stock Agreement (assuming, as to Buyer Common Stock issued under the Stock Agreement, that the representations and warranties of the parties other than Buyer set forth in the Stock Agreement regarding their acquisition of Buyer Common Stock are true and correct), will comply in all respects with the provisions of the Securities Act, the Exchange Act, all applicable state securities or "Blue Sky" laws, and, where applicable, the laws and regulations of all foreign jurisdictions. (v) The Convertible Notes have been duly authorized, executed, delivered and paid for in accordance with the terms of their issuance, are valid and binding obligations of the Buyer, enforceable in accordance with their terms, subject to applicable bankruptcy, insolvency or similar laws affecting creditors' rights generally and general principles of equity. The underlying shares of Buyer Common Stock issuable upon conversion of the Convertible Notes have been duly authorized and reserved and, when issued upon conversion of the Convertible Notes in accordance with their terms, will be validly issued, fully paid and non assessable, and the issuance of such shares of Buyer Common Stock will not be subject to any preemptive or similar rights. The offering and sale of the Convertible Notes (i) did not require the registration or qualification thereof under the Securities Act or any applicable state securities or "Blue Sky" laws, nor was any indenture with respect thereto required to be qualified under the Trust Indenture Act of 1939, as amended, and (ii) were made in compliance with Section 4(2) of the Securities Act and in accordance with Regulation D promulgated by the SEC thereunder. (h) Buyer SEC Filings. 25 (i) The Buyer has filed all forms, statements, reports and documents required to be filed or, if permissible, furnished by it with the Securities and Exchange Commission (the "SEC") since the incorporation of Buyer (collectively, the "Buyer SEC Reports"). The Buyer SEC Reports (i) were prepared in accordance with the requirements of the Securities Act or the Exchange Act, as the case may be, and the rules and regulations promulgated thereunder, and (ii) did not, at the time they were filed, or, if amended, as of the date of such amendment, contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements made therein, in the light of the circumstances under which they were made, not misleading. As of its filing date, each Buyer SEC Report complied as to form in all material respects with the applicable requirements of the Securities Act and the Exchange Act, as the case may be, and no Subsidiary of Buyer is required to file any form, report or other document with the SEC pursuant to the Exchange Act. (ii) Each of the financial statements (including, in each case, any notes thereto) contained in the Buyer SEC Reports was prepared in accordance with GAAP applied on a consistent basis throughout the periods indicated (except as may be indicated in the notes thereto or, in the case of unaudited statements, as permitted by Form 10-QSB of the SEC) and each fairly presents, in all material respects, the financial position, results of operations and cash flows of the Buyer at the respective dates thereof and for the respective periods indicated therein, except as otherwise noted therein (subject, in the case of unaudited statements, to normal year end adjustments of a generally recurring nature). (iii) Except as and to the extent set forth in the Buyer SEC Reports filed with the SEC prior to the date hereof, the Buyer has no liability or obligation of any nature (whether accrued, absolute, contingent or otherwise), except for (i) their performance obligations under contracts existing on the date hereof or under applicable laws or regulations, in each case to the extent arising after the date hereof, (ii) liabilities and obligations incurred in the Ordinary Course of Business since September 30, 2005 and (iii) liabilities and obligations which, individually or in the aggregate, would not reasonably be expected to prevent or materially delay consummation of the transactions contemplated herein or otherwise prevent or materially delay the Buyer from performing its obligations under this Agreement, and which in each case would not reasonably be expected, individually or in the aggregate, to have a material adverse effect on the financial condition of the Buyer or on the ability of the Parties to consummate the transactions contemplated by this Agreement. (iv) The Buyer has timely filed all certifications and statements required by (i) Rule 13a-14 or Rule 15d-14 under the Exchange Act or (ii) 18 U.S.C. Section 1350 (Section 906 of the Sarbanes-Oxley Act of 2002) with respect to any Buyer SEC Report and has made such certifications and statements filed prior to the date hereof available to the Sellers. The Buyer maintains disclosure controls and procedures required by Rule 13a-15 or Rule 15d-15 under the Exchange Act; such controls and procedures are effective to ensure that all material information concerning the Buyer and its Subsidiaries is made known on a timely basis to the individuals responsible for the preparation of the Buyer's SEC filings and other public disclosure documents. Schedule 4(h) of the Buyer's Disclosure Schedule lists, and the Buyer has made available to the Sellers, complete and correct copies of, all written descriptions of, and all policies, manuals and other documents promulgating such disclosure controls and procedures. As used in this Section 4(h), the term "file" shall be broadly construed to include any manner in which a document or information is furnished, supplied or otherwise made available to the SEC. 26 (v) The management of the Buyer has disclosed, based on its most recent evaluation as of the date of this Agreement, to the Buyer's outside auditors and the audit committee of the Board of Directors of the Buyer (i) all significant deficiencies and all material weaknesses in the design or operation of internal control over financial reporting (as defined in Rule 13a-15 under the Exchange Act) known to the Buyer as of the date of such evaluation which are reasonably likely to materially and adversely affect the Buyer's ability to record, process, summarize and report financial data, and (ii) any fraud, whether or not material, that involved management or other employees who have a significant role in the Buyer's internal controls over financial reporting. (vi) The Buyer maintains a system of internal accounting controls sufficient to provide reasonable assurance that (1) transactions are executed in accordance with management's general or specific authorizations; (2) transactions are recorded as necessary to permit preparation of financial statements in conformity with generally accepted accounting principles and to maintain accountability for assets; (3) access to assets is permitted only in accordance with management's general or specific authorization; and (4) the recorded accountability for assets is compared with the existing assets at reasonable intervals and appropriate action is taken with respect to any differences. (vii) There has not occurred any material adverse change, or any development constituting a prospective material adverse change, in the condition, financial or otherwise, or in the earnings, business or operations of the Buyer taken as a whole, from that set forth in the September 10-QSB.

(x) Neither the offer or sale of the shares of Buyer Common Stock pursuant to the Stock Agreement nor the consummation of the transactions as contemplated by this Agreement give rise to any rights for or relating to the registration of shares of Buyer Common Stock or other securities of the Buyer, except as may be granted incident to the Private Placement referred to in Section 2(d) or the Closing Placements referred to in Section 5(k) hereof. (xi) Except with respect to the issuance on November 23, 2005 of $2,375,000 in original principal amount of Convertible Notes due May 2007, subsequent to September 30, 2005, (1) the Buyer and its subsidiaries have not incurred any material liabilities or obligations, direct or contingent, nor entered into any material transactions not in the Ordinary Course of Business; (2) the Buyer has not purchased any of its outstanding capital stock, nor declared, paid or otherwise made any dividend or distribution of any kind on its capital stock; and (3) there has not been any material change in the capital stock, short-term debt or long-term debt of the Buyer, except as described in the September 10-QSB.

There is no litigation, suit, claim, action, proceeding or investigation pending or, to the knowledge of the Buyer, threatened against the Buyer, or any property or asset of the Buyer, before any Governmental Authority that (a) has had, or would reasonably be expected to have, a material adverse effect on the financial condition of the Buyer or on the ability of the Parties to consummate the transactions contemplated by this Agreement or (b) as of the date hereof seeks to materially delay or prevent the consummation of the transactions contemplated hereunder. Neither the Buyer nor any property or asset of the Buyer is subject to any continuing order of, consent decree, settlement agreement or other similar written agreement with, or, to the knowledge of the Buyer, continuing investigation by, any Governmental Authority, or any order, writ, judgment, injunction, decree, determination or award of any Governmental Authority, that would reasonably be expected, individually or in the aggregate, to prevent or materially delay consummation of the transactions contemplated hereunder or otherwise prevent or materially delay the Buyer from performing its obligations under this Agreement or would reasonably be expected to have a material adverse effect on the financial condition of the Buyer or on the ability of the Parties to consummate the transactions contemplated by this Agreement. 28 (k) Hart-Scott-Rodino Act Filings. To the Buyer's knowledge, the transactions contemplated by this Agreement and the Stock Agreement do not require any filing under or submission under the Hart-Scott-Rodino Act nor under any other applicable antitrust or competition law or regulation of any Governmental Authority having jurisdiction with respect to the transactions contemplated hereunder and under the Stock Agreement.

The cash available to the Buyer, after taking into account all other anticipated uses of the cash of the Buyer, will be sufficient to pay all such judgments promptly in accordance with their terms. As used in this Section 4(l), "insolvent" means, for any Person, that the sum of the present fair saleable value of its assets does not and/or will not exceed its debts and other probable liabilities, and (y) the term "debts" includes any legal liability, whether matured or unmatured, 1iquidated or unliquidated, absolute, fixed or contingent, disputed or undisputed or secured or unsecured. 5.

Within three (3) days after expiration of such five (5) days period, each of Sellers and Buyers shall appoint an arbitrator, who shall be (i) in the case of a dispute regarding debt covenants, a banker experienced in oil and gas lending and (ii) in the case of any other dispute, an investment banker experienced in oil and gas investment banking, and shall give notice of such appointment to the Buyer or Sellers, as applicable.

Until such approvals and consents are obtained, the respective Sellers shall continue to hold legal title to such Acquired Assets as nominee for the Buyer. No Seller shall be obligated to incur any expenses in such Seller's capacity as nominee. The Sellers and the Buyer shall treat and deal with such Acquired Assets as if full legal and equitable title to such Acquired Assets had passed from the Sellers to the Buyer at such Closing. (m) Further Assurances. The Sellers and the Buyer each agree that, from time to time, whether before, at or after any Closing Date, each of them will execute and deliver or cause their respective Affiliates to execute and deliver such further instruments of conveyance and transfer and take such other action as may be necessary to carry out the purposes and intents of this Agreement. 6. Conditions to Obligation to Close. (a) Conditions to Obligation of the Buyer. The obligation of the Buyer to consummate the transactions to be performed by it in connection with the Closing is subject to satisfaction of the following conditions: (i) the representations and warranties set forth in Section 3 above shall be true and correct in all material respects at and as of the Closing Date; (ii) the Sellers shall have performed and complied with all of their covenants hereunder in all material respects through the Closing; (iii) there shall not be any injunction, judgment, order, decree, ruling, or charge in effect preventing consummation of any of the transactions contemplated by this Agreement; (iv) the Sellers shall have delivered to the Buyer a certificate to the effect that each of the conditions specified above in Section 6(a)(i)-(iii) is satisfied in all respects; 37 (v) the Buyer shall have received all other authorizations, consents, and approvals of governments and governmental agencies referred to in Sections 3(d) and 4(d) above; (vi) the Buyer shall have obtained the Financing Amount incident to closing of the Closing Placements referred to in Section 5(k) above; (vii) the property inspections and due diligence conducted by Buyer with respect to the NS Reports shall have met the conditions set forth in Section 2(f)(i); (viii) Sellers shall have purchased and paid for in immediately available funds ten percent (10%) of the Buyer Securities incident to the Closing Placements referred to in Section 5(k), as provided for in the Stock Agreement; (ix) Sellers (except for PennTex Illinois) shall have delivered complete copies of their Balance Sheets and Income Statements as of, and for the fiscal years ended, December 31, 2004 and December 31, 2005, audited by an SEC qualified independent accounting firm and unaudited balance sheets and income statements as of, and for the quarter ended, March 31, 2006; (x) PennTex Illinois shall have delivered complete copies of its Balance Sheet and Income Statement as of, and for the fiscal year ended, December 31, 2005 audited by an SEC qualified independent accounting firm and an unaudited balance sheet and income statement as of, and for the quarter ended, March 31, 2006; (xi) all actions to be taken by the Sellers in connection with consummation of the transactions contemplated hereby and all certificates, opinions, instruments, and other documents required to effect the transactions contemplated hereby will be reasonably satisfactory in form and substance to the Buyer; and (xii) In Exhibit D describing the Wells included in the Acquired Assets, Sellers have included a statement as to Sellers' Net Revenue Interest as to each Well (i.e., the percentage of total (8/8ths) oil and gas to be produced from the Well which Sellers are believed to be entitled to receive and retain after payment or deduction of all outstanding royalties, overriding royalties, net profits interests and other burdens or interests owned by parties other than Sellers). Sellers have endeavored to provide this information as to Sellers' Net Revenue Interests based on Sellers' records, but it is expressly stipulated and agreed that Sellers do not and will not represent or warrant that Sellers do, in fact, own or are entitled to receive or retain the Net Revenue Interest shown in Exhibit D of oil or gas produced or to be produced from any Well or Wells or that back-ins, reversionary interests or other deferred interests do not exist that may reduce Sellers' Net Revenue Interest in oil or gas produced from any Well or Wells at some time in the future below the Net Revenue Interest stated in Exhibit D. To the contrary, it is expressly stipulated and agreed that Sellers shall have no liability for any error, misstatement, overstatement or erroneous statement of Sellers' Net Revenue Interest with respect to any Well shown in Exhibit D, and that Buyer's sole remedy for any overstatement of Sellers' Net Revenue Interest with respect to any Well shown in Exhibit D shall be to require such reduction, if any, in the Purchase Price as is provided for hereinafter in this paragraph. From the date of this Agreement to April 1, 2006, Sellers shall make available to Buyer and its attorneys and representatives in Sellers' offices for review and inspection and copying all title information and material possessed by Sellers with respect to the Acquired Assets, including, without limitation, title opinions, division orders, Lease, Well and Unit files, payment and accounting records and other files or records that may reasonably assist Buyer in determining whether any title defects or deficiencies exist with respect to any Acquired Assets. If Buyer determines that title defects or deficiencies or outstanding interests of third parties exist with respect to any Well that will reduce the Net Revenue Interest as to such Well as to which Sellers hold "Commercially Defensible Title" (as herein defined) below the Net Revenue 38 Interest shown in Exhibit D, Buyer may give written notice (a "Title Defect Notice") to Sellers at any time on or prior to April 1, 2006, describing such title defect or deficiency or outstanding interest (collectively, a "Title Deficiency") and specifying the extent, if any, of the Net Revenue Interest as to such Well (the "Reduced Net Revenue Interest") to which Buyer has determined Sellers do hold Commercially Defensible Title, As used herein, "Commercially Defensible Title" to a Net Revenue Interest as to a Well means a claim of title that in reasonable probability could be sustained by Sellers in litigation in a court of competent jurisdiction against adverse claimants asserting claims of title to oil or gas produced or to be produced from such Well based on the Title Deficiency described in a Title Defect Notice given with respect to such Well, based on evidence of Sellers' record title, Sellers' claims of title by adverse possession or prescription, or other claims of title by Sellers under applicable principles of law or equity. If Buyer timely gives a Title Defect Notice with respect to a Well, Sellers may dispute such Title Defect Notice by giving a notice (a "Dispute Notice") to Buyer within ten (10) days after receipt of the Title Defect Notice. Failure to give a Dispute Notice within such ten (10) days period shall constitute agreement by Sellers that Sellers have Commercially Defensible Title to a Net Revenue Interest as to such Well equal only to the Reduced Net Revenue Interest (if any) specified in the Title Defect Notice (which shall be deemed to be the "Agreed Net Revenue Interest" as to such Well). If Sellers timely give a Dispute Notice in response to a Title Defect Notice, the Parties shall endeavor to agree as to the extent, if any, of the Net Revenue Interest as to such Well as to which Sellers hold Commercially Defensible Title (the "Agreed Revenue Interest"). If the Parties do not reach agreement within ten (10) days after Buyer's receipt of the Dispute Notice, the dispute shall be resolved by final, binding arbitration as hereinafter provided. Within five (5) days after expiration of such ten (10) days period, each of Sellers and Buyers shall appoint an arbitrator, who shall be an attorney experienced in oil and gas title law matters and give notice of such appointment to the Buyer or Sellers, as applicable. Within five (5) days after the two (2) arbitrators have been appointed, the two (2) arbitrators shall select a third arbitrator who shall likewise be an attorney experienced in oil and gas title law matters. The Sellers shall make available to the arbitrators all relevant title information possessed by Sellers, and the Sellers and Buyer may make written presentations or, if the arbitrators so direct, oral arguments before the arbitrators. The decision of at least two (2) of the three (3) arbitrators as to the extent, if any, of the Net Revenue Interest as to the Well as to which Sellers hold Commercially Defensible Title shall be rendered prior to the Closing Date and shall be final and binding on the Parties. If the Net Revenue Interest as determined by the Arbitrators is less than the Net Revenue Interest as to a Well shown in Exhibit D, such Net Revenue Interest determined by the arbitrators shall be deemed to be the "Agreed Net Revenue Interest" as to such Well. If Dispute Notices given as to more than one Well are not resolved by agreement within the applicable ten (10) day period as provided above, the resolution of all such Dispute Notices as to all Wells shall be submitted to and resolved by the single board of arbitrators appointed as above provided following giving of the first Dispute Notice that is not resolved by agreement. As to each Well as to which an Agreed Net Revenue Interest less than the Net Revenue Interest shown in Exhibit D is determined as hereinabove provided, a "Reduction Amount" shall calculated equal to: (i) An amount (the "NS Reports Amount") equal to 70% of the discounted present value of future oil and/or gas production from the Well reflected in the NS Reports using a 10% discount factor; minus 39 (i) An amount equal to a fraction of the NS Reports Amount determined by multiplying the NS Reports Amount by a fraction having the Agreed Net Revenue Interest for the Well as its numerator and having the Net Revenue Interest for the Well shown in Exhibit __ as its denominator. The total of the Reduction Amounts (if any) determined for all Wells shall be applied first against any remaining amount of the Sellers' Basket provided for in Section 8(e)(iii) in excess of claims of the Buyer Indemnified Parties under Section 8(b) that have been applied toward satisfaction of such Sellers' Basket and, to the extent so applied, shall reduce or satisfy the Sellers' Basket available to be credited against claims of the Buyer Indemnified Parties pursuant to Section 8(e)(iii). The cash portion of the Purchase Price provided for in Section 2(d) shall be reduced by the amount, if any, of the excess of the total Reduction Amounts that are not thus credited against the Sellers Basket; provided that, if the total reduction of the Purchase Price for such Reduction Amounts would exceed $3,658,499.95, unless Buyer agrees to limit the reduction of the cash portion of the Purchase Price to $3,658,499.95, Sellers shall have the right, in Sellers' discretion, to terminate this Agreement by giving a written notice of termination ("Termination Notice") to Buyer at any time on or prior to the earlier of (i) ten (10) days after resolution by agreement or issuance of a final arbitrators award of all Dispute Notices concerning all Wells or (ii) the Closing Date, in which event this Agreement will terminate and the Closing will not occur unless Sellers and Buyer thereafter mutually agree to effect the Closing pursuant to such amendments of this Agreement regarding the Purchase Price, the Acquired Assets, or other terms of this Agreement as shall be agreeable and acceptable to each of Sellers and Buyer, each in its or their sole discretion. (b) Conditions to Obligation of the Sellers. The obligation of the Sellers to consummate the transactions to be performed by it in connection with the Closing is subject to satisfaction of the following conditions: (i) the representations and warranties set forth in Section 4 above shall be true and correct in all material respects at and as of the Closing Date; (ii) the Buyer shall have performed and complied with all of its covenants hereunder in all material respects through the Closing; (iii) there shall not be any injunction, judgment, order, decree, ruling, or charge in effect preventing consummation of any of the transactions contemplated by this Agreement; (iv) the Buyer shall have delivered to the Sellers a certificate to the effect that each of the conditions specified above in Section 6(b)(i)-(iii) is satisfied in all respects; (v) the Buyer shall have received all other authorizations, consents, and approvals of governments and governmental agencies referred to in Sections 3(d) and 4(d) above; (vi) the Buyer shall have obtained the Financing Amount incident to closing of the Closing Placements referred to in Section 5(k) above; (vii) all actions to be taken by the Buyer in connection with consummation of the transactions contemplated hereby and all certificates, opinions, instruments, and other documents required to effect the transactions contemplated hereby will be reasonably satisfactory in form and substance to the Sellers; and 40 (viii) Buyer shall have issued the Buyer Securities to be purchased by Sellers incident to the Closing Placements described in Section 5(k), as provided for in the Stock Agreement, and such Buyer Securities shall be validly issued, fully paid, and non-assessable. The Sellers may waive any condition specified in this Section 6(b) if they execute a writing so stating at or prior to the Closing. 7. Termination. (a) Termination of Agreement.

The Sellers (except for Shaner and Hulburt, who shall have no liability or obligation to the Buyer or any Buyer Indemnified Party hereunder and shall not, for purposes of the Seller's obligations to indemnify hereunder, be deemed "Sellers") shall indemnify Buyer and each of the directors, officers, employees and Affiliates of Buyer, and each of their successors and assigns (individually, a "Buyer Indemnified Party"), and hold them, and each of them, harmless from, against and in respect of any and all costs, losses, claims, liabilities (including for Taxes), fines, penalties, damages (other than special, consequential or punitive damages) and expenses (including interest, if any, imposed in connection therewith, court costs and reasonable fees and disbursements of counsel) (collectively, "Damages") incurred by any of them resulting from: (i) any claim, liability, obligation or expense arising out of or related to the operation of the Acquired Assets prior to the applicable Effective Time (except for such claims, liabilities, obligations, costs or expenses that have been expressly assumed by the Buyer hereunder, including the Assumed Liabilities and such liabilities and obligations for which the Buyer has agreed hereunder to be responsible) and (ii) any breach of any representation or warranty in this Agreement or the non-fulfillment in any material respect of any agreement, covenant or obligation by the Sellers made in this Agreement (including without limitation any Exhibit or Schedule hereto and any certificate or instrument delivered in connection herewith). As more fully provided in Section 9(a), the indemnification obligations of the respective Sellers hereunder shall be several and not joint, and shall obligate each Seller with respect only to itself or its own actions or omissions or representations or warranties or interests in the Acquired Assets. (c) Indemnification by the Buyer. The Buyer shall indemnify each Seller and each of the shareholders, directors, partners, employees, Affiliates and "associates" (as that term is defined in Rule 405 promulgated by the SEC under the Securities Act) of the Sellers (individually a "Seller Indemnified Party") and hold them, and each of them, harmless from, against and in respect of any and all Damages incurred by such Seller Indemnified Party resulting from (i) any claim, liability, obligation or expense arising out of or related to the operation of the Acquired Assets on or after the applicable Effective Time and (ii) any misrepresentation, breach of any representation or warranty in this Agreement or the non-fulfillment in any material respect of any agreement, covenant or obligation by Buyer made in this Agreement (including without limitation any Exhibit or Schedule hereto and any certificate or instrument delivered in connection herewith). 42 (d) Sole and Exclusive Remedy. The sole and exclusive remedy and recourse of the Buyer Indemnified Parties against the Sellers with respect to or directly relating to the matters set forth in Section 8(b) hereof shall be pursuant to this Section 8. The sole and exclusive remedy and recourse of the Seller Indemnified Parties against the Buyer with respect to or directly relating to the matters set forth in Section 8(c) hereof shall be pursuant to this Section 8. (e) Limitations on Indemnification. (i) The Seller Indemnified Parties shall not be entitled to assert any claim for indemnification under this Section 8 unless and until such time as all claims of the Seller Indemnified Parties for indemnification hereunder exceed $1,000,000 (the "Buyer's Basket") in the aggregate, at which time any and all claims of the Seller Indemnified Parties for indemnification in excess of the Buyer's Basket may be asserted; provided, however, that the Buyer's Basket shall not be applicable to any Damages attributable to (A) any breach by the Buyer of any of its obligations under Section 2(e) hereof, or (B) any failure of the Buyer to pay or otherwise satisfy any part of the Assumed Liabilities or any other obligations or liabilities of the Sellers that the Buyer has agreed to assume and be responsible for under the terms of this Agreement. (ii) Notwithstanding anything to the contrary contained in this Section 8, in no event will any Seller be liable to the Buyer or any Buyer Indemnified Party under this Section 8 or otherwise (A) in an amount in excess of the amounts shown on Schedule 8(e) of the Sellers' Disclosure Schedule with respect to each Seller individually, and $36,585,000 with respect to all of the Sellers in the aggregate, or (B) for any incidental, consequential or other special damages, including, without limitation, lost profits. (iii) The Buyer Indemnified Parties shall not be entitled to assert any claim for indemnification under this Section 8 unless and until such time as all claims of the Buyer Indemnified Parties for indemnification hereunder exceed $1,000,000 (the "Sellers' Basket") in the aggregate, at which time any and all claims of the Buyer Indemnified Parties for indemnification in excess of the Sellers' Basket may be asserted; provided, however, that the Sellers' Basket shall not be applicable to any Damages attributable to any breach by the Sellers of any of their obligations under Section 2(e) hereof. (iv) Notwithstanding anything to the contrary contained in this Section 8, in no event will the Buyer be liable to the Sellers or any Seller Indemnified Party under this Section 8 or otherwise (A) in an amount in excess of $15,000,000, or (B) for any incidental, consequential or other special damages, including, without limitation, lost profits. (v) Notwithstanding any provision to the contrary contained in this Agreement, no Seller shall have any liability to the Buyer hereunder to the extent that the existence of such liability, breach, or falsity of any representation upon which such liability would be based is disclosed in any of the contracts, certificates and documents referred to in this Agreement, the Exhibits attached hereto or in the Sellers' Disclosure Schedules accompanying herewith, or otherwise disclosed in a written notice to Buyer prior to the Closing Date. (f) Right to Defend. If the facts giving rise to any such indemnification shall involve any actual claim or demand by any third party against a Buyer Indemnified Party or Seller Indemnified Party (referred to herein as an "Indemnified Party"), then the Indemnified Party will give prompt written notice of any such claim to the indemnifying party, which notice shall set forth in reasonable detail the nature, basis and amount of such claim (the "Notice of Third Party Claim"). It is a condition precedent to the applicable indemnifying party's obligation to indemnify the applicable Indemnified Party for such claim that such Indemnified Party timely provide to such indemnifying party the applicable Notice of Third Party Claim, provided that the failure to provide such Notice of Third Party Claim shall only relieve such indemnifying party of its or his obligation to indemnify for such claim only to the extent that such 43 indemnifying party has been prejudiced by such Indemnified Party's failure to give the Notice of Third Party Claim as required. The indemnifying party receiving such Notice of Third Party Claim may (without prejudice to the right of any Indemnified Party to participate at its own expense through counsel of its own choosing) undertake the defense of such claims or actions at its expense with counsel chosen and paid by its giving written notice (the "Election to Defend") to the Indemnified Party within thirty (30) days after the date the Notice of Third Party Claim is deemed received; provided, however, that the indemnifying party receiving the Notice of Third Party Claim may not settle such claims or actions without the consent of the Indemnified Party, which consent will not be unreasonably withheld or delayed, except if the sole relief provided is monetary damages to be borne solely by the indemnifying party; and, provided further, if the defendants in any action include both the indemnifying party and the Indemnified Party, and the Indemnified Party shall have reasonably concluded that counsel selected by the indemnifying party has a conflict of interest because of the availability of different or additional defenses to the parties, the Indemnified Party shall cooperate in the defense of such claim and shall make available to the indemnifying party pertinent information under its control relating thereto, but the Indemnified Party shall have the right to its own counsel and to control its defense and shall be entitled to be reimbursed for all reasonable costs and expenses incurred in such separate defense. In no event will the provisions of this Section reduce or lessen the obligations of the parties under this Section, if prior to the expiration of the foregoing thirty (30) day notice period, the Indemnified Party furnishing the Notice of Third Party Claim responds to a third party claim if such action is reasonably required to minimize damages or avoid a forfeiture or penalty or because of any requirements imposed by law. If the indemnifying party receiving the Notice of Third Party Claim does not duly give the Election to Defend as provided above, then it will be deemed to have irrevocably waived its right to defend or settle such claims, but it will have the right, at its expense, to attend, but not otherwise to participate in, proceedings with such third parties; and if the indemnifying party does duly give the Election to Defend, then the Indemnified Party giving the Notice of Third Party Claim will have the right at its expense, to attend, but not otherwise to participate in, such proceedings. The parties to this Agreement will not be entitled to dispute the amount of any damages (including reasonable attorney's fees and expenses) related to such third party claim resolved as provided above. (g) Subrogation. If the Indemnified Party receives payment or other indemnification from the indemnifying party hereunder, the indemnifying party shall be subrogated to the extent of such payment or indemnification to all rights in respect of the subject matter of such claim to which the Indemnified Party may be entitled, to institute appropriate action against third parties for the recovery thereof, including under any insurance policies, and the Indemnified Party agrees to assist and cooperate in good faith with the indemnifying party and to take any action reasonably required by such indemnifying party, at the expense of such indemnifying party, in enforcing such rights. 9.

(iii) The Executive's conviction for a felony offense under the laws of the United States or any state thereof. (iv) Willful breach by the Executive of any restrictive covenant contained in Sections 12 and 13 of this Agreement. For purposes of this definition, no act or failure to act will be deemed "willful" unless effected by the Executive not in 1 good faith and without a reasonable belief that his action or failure to act was in or not opposed to the Corporation's best interests. (c) "Change in Control" means and shall be deemed to have occurred if: (i) any "person" as such term is used in Sections 13(d) and 14(d) of the Securities Exchange Act of 1934, as amended (the "Exchange Act") (other than the Corporation, any trustee or other fiduciary holding securities under any employee benefit plan of the Corporation, or any entity owned, directly or indirectly, by the shareholders of the Corporation in substantially the same proportions as their ownership of the voting securities of the Corporation), including a "group" as defined in Section 13(d)(3) of the Exchange Act, is or becomes the "beneficial owner" (as defined in Rule 13d-3 under the Exchange Act, or any successor rule or regulation thereto as in effect from time to time), directly or indirectly, of securities representing 50% or more of the combined voting power of the Corporation's then outstanding securities; (ii) during any 12-month period (not including any period prior to the date of this Agreement), individuals who at the beginning of such period constitute the Board of Directors, and any new director (other than a director designated by a person who has entered into an agreement with the Corporation to effect a transaction described in clause (i) or (iii) of this paragraph) whose election by the Board of Directors or nomination for election by the Corporation's shareholders was approved by a vote of at least majority of the directors then still in office who either were directors at the beginning of such 12-month period or whose election or nomination for election was previously approved, cease for any reason to constitute at least a majority of the Board of Directors; (iii) any "person" as such term is used in Sections 13(d) and 14(d) of the Exchange Act (other than the Corporation, any trustee or other fiduciary holding securities under any employee benefit plan of the Corporation, or any entity owned, directly or indirectly, by the shareholders of the Corporation in substantially the same proportions as their ownership of the voting securities of the Corporation), including a "group" as defined in Section 13(d)(3) of the Exchange Act, acquires (or has acquired during the 12-month period ending on the date of the most recent acquisition by such person or persons) ownership of stock of the corporation possessing 35% or more of the combined voting power of the Corporation's then outstanding securities; or (iv) any "person" as such term is used in Sections 13(d) and 14(d) of the Exchange Act, including a "group" as defined in Section 13(d)(3) of the Exchange Act, acquires (or has acquired during the 12-month period ending on the date of the most recent acquisition by such person or persons) assets from the Corporation that have a total gross fair market value equal to or more than 40% of the total gross fair market value of all of the assets of the Corporation immediately prior to such acquisition or acquisitions; provided, however, that transfer in the ownership of a substantial portion of the Corporation's assets to an entity controlled by the Corporation does not constitute a Change in Control. For this purpose, gross fair market value means the value of the assets of the Corporation, or the value of the assets being disposed of, determined without regard to any liabilities associated with such assets. 2 If any of the events enumerated in clause (i) through (iv) occur, the Corporation's Board of Directors shall determine in good faith the effective date of the Change in Control resulting therefrom for purposes of this Agreement.

Any question as to the existence of a physical or mental impairment which would give rise to the Disability of the Executive under clause (x) upon which the Executive and the Corporation cannot agree will be determined by a qualified independent physician selected by the Executive and reasonably acceptable to the Corporation (or, if the Executive is unable to make a selection, the selection of the physician will be made by any adult member of his immediate family). The physician's written determination to the Corporation and to the Executive will be final and conclusive for all purposes of this Agreement. (g) "Good Reason" means: (i) A material diminution in the Executive's responsibilities, duties, title, reporting responsibilities within the business organization, status, role or authority which is not restored within thirty (30) days after written notice of such diminution is provided to the Corporation.

(i) "Termination Payment Commencement Date" shall mean with respect to a payment required hereunder (i) if the Board of Directors (or its delegate) determines in its sole discretion that as of the date of the Executive's termination the Executive is a "specified employee" (as defined in Section 409A(a)(2)(B)(i) of the Code, and Department of Treasury regulations and other interpretive guidance issued thereunder) as of the date of the Executive's termination and that Section 409A of the Code applies with respect to such payment, the first business day following the six-month anniversary of the date of the Executive's Termination; or (ii) if the Board of Directors (or its delegate) determines in its sole discretion that the Executive is not such a "specified employee" as of the date of the Executive's termination or that Section 409A of the Code does not apply with respect to such payment, within 30 days following the date of the Executive's termination. The period commencing on the Executive's date of termination and ending on the six-month anniversary of such date is referred to herein as the "Six-Month Delay Period". 2. Employment; Duties.

The Executive will perform those duties and discharge those responsibilities as are commensurate with his position, and 4 as the Board of Directors may from time to time reasonably direct that are commensurate with his position. The Executive agrees to perform his duties and discharge his responsibilities in a faithful manner and to the best of his ability and to use all reasonable efforts to promote the interests of the Corporation.

In addition, if the Board of Directors (or its delegate) determines in its sole discretion that Section 409A of the Code applies to any health or medical Fringe Benefit that is to be provided to Executive (or his dependents) pursuant to Sections 8(b) or (e) and that the Executive is a "specified employee" as of the date of the Executive's termination, such Fringe Benefit shall not be provided during the Six-Month Delay Period; provided, however, that, Executive and his dependent shall be eligible to participate in and may elect to receive continued coverage under the Corporation's (or Rex Energy Operating, Corp.'s, if applicable) health and medical plans in which he previously participated in accordance with the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended ("COBRA") or any successor law during the Six-Month Delay Period, and the Corporation shall reimburse Executive on the Termination Payment Commencement Date the total amount of COBRA premiums Executive (or his dependents) paid during such period; provided, further, that thereafter, for the remainder of the Payment Period, the Corporation shall provide the Executive with the health and medical Fringe Benefits he would have originally been provided if he were not classified as a "specified employee" and Section 409A did not apply to the provision of such benefits. (h) Indemnity.

Additional Payments. 11 (a) Notwithstanding anything in this Agreement or any other agreement to the contrary, in the event it is determined that any payments or distributions (including, without limitation, the vesting of an option or other non-cash benefit or property or the forgiveness of any indebtedness) by the Corporation or any affiliate (as defined under the Securities Act of 1933, as amended, and the regulations thereunder) thereof or any other person to or for the benefit of the Executive, whether paid or payable pursuant to the terms of this Agreement, or pursuant to any other agreement or arrangement with the Corporation or any such affiliate ("Payments"), would be subject to the excise tax imposed by Section 4999 of the Code, or any successor provision, or any interest or penalties with respect to the excise tax (the excise tax, together with any interest and penalties, are hereinafter collectively referred to as the "Excise Tax"), then the Executive will be entitled to receive an additional payment from the Corporation (a "Gross-Up Payment") in an amount that after payment by the Executive of all taxes (including, without limitation, any interest or penalties imposed with respect to such taxes and any Excise Tax) imposed upon the Gross-Up Payment, the Executive retains an amount of the Gross-Up Payment equal to the Excise Tax imposed upon the Payments. The amount of the Gross-Up Payment will be calculated by the Corporation's independent accounting firm, engaged immediately prior to the event that triggered the payment, in consultation with the Corporation's outside legal counsel. For purposes of making the calculations required by this Section, the accounting firm may make reasonable assumptions and approximations concerning applicable taxes and may rely on reasonable, good faith interpretations concerning the application of Sections 280G and 4999 of the Code, provided that the accounting firm's determinations must be made with substantial authority (within the meaning of Section 6662 of the Code). The Gross-Up Payment will be paid on the Executive's last day of employment or on the occurrence of the event that results in the imposition of the Excise Tax, if later. If the precise amount of the Gross-Up Payment cannot be determined on the date it is to be paid, an amount equal to the best estimate of the Gross-Up Payment will be made on that date and, within 10 days after the precise calculation is obtained, either the Corporation will pay any additional amount to the Executive or the Executive will pay any excess amount to the Corporation, as the case may be. If subsequently the Internal Revenue Service (the "IRS") claims that any additional Excise Tax is owing, an additional Gross-Up Payment will be paid to the Executive within 30 days of the Executive providing substantiation of the claim made by the IRS. After payment to the Executive of the Gross-Up Payment, the Executive will provide to the Corporation any information reasonably requested by the Corporation relating to the Excise Tax, the Executive will take those actions as the Corporation reasonable requests to contest the Excise Tax, cooperate in good faith with the Corporation to effectively contest the Excise Tax and permit the Corporation to participate in any proceedings contesting the Excise Tax. The Corporation will bear and pay directly all costs and expenses (including any interest or penalties on the Excise Tax), and indemnify and hold the Executive harmless, on an after-tax basis, from all such costs and expenses related to such contest. Should it ultimately be determined that any amount of an Excise Tax is not properly owed, the Executive will refund to the Corporation the related amount of the Gross-Up Payment. (b) The Corporation has issued shares (the "Shares") to Executive pursuant to a certain Stock Agreement dated as of January 16, 2006. The Corporation and Executive intended to effect a completed transfer of the Shares and, thereby, make any taxable gain attributable to the Shares eligible for long-term capital gains treatment (after the Shares have been held for one year). Accordingly, if after the first anniversary of the issuance of the Shares it is finally determined that a taxable gain on such shares is subject to tax at ordinary income tax rates, then the Corporation shall pay to the Executive (or any permitted transferee of Executive), a "Gross-Up Payment" in an amount such that, after payment by the Executive (or such permitted transferee) of all taxes imposed upon the Gross-Up Payment, the Executive (or such permitted transferee) retains an amount of the Gross-Up Payment equal to the difference, if any, between (x) the federal and state income tax rate for long-term capital gain items and (y) the federal and state income tax rate for ordinary income items (at the highest marginal tax bracket applicable to the Executive or such permitted transferee), as in effect on the date of the sale multiplied by such taxable gain. 12 (c) If any Gross-Up Payment required pursuant to this Section 9 is determined by the Board of Directors (or its delegate) to be subject to Section 409A of the Code, such payment shall be made as follows: (i) if such Gross-Up Payment is made due to a Change in Control (i.e., such payment or provision is made without taking into account Executive's termination), then the Corporation shall pay such Gross-Up Payment on the date of the Change in Control or, if later, as soon as administratively practicable following the accounting firm's determination described in Section 9(a); (ii) if such Gross-Up Payment is made on or after, and due to, Executive's termination, then the Corporation shall pay such Gross-Up Payment incurred during the Six-Month Delay Period in a lump sum on the Termination Payment Commencement Date, and for each calendar month thereafter in which such a Gross-Up Payment becomes due in monthly installments on the last business day of the calendar month following the month such payment becomes due; and (iii) if such Gross-Up Payment is due to a subsequent IRS claim that an additional Excise Tax is owed or due under Section 9(c), then the Corporation shall pay such Gross-Up Payment no later than March 15th of the calendar year following the calendar year in which the alleged obligation of Executive, as reflected by Executive's receipt of a claim by the IRS, is received by Executive or it is finally determined that a taxable gain on the Shares described in Section 9(c) is subject to tax at ordinary income tax rates; and (iv) notwithstanding Sections 9(c)(i) or (ii), if a Gross-Up Payment due under Section 9 is paid due to a Change in Control or on or after, and due to, the Executive's termination, such payment will be considered a distribution payable on the date of the Change in Control or the Executive's date of Termination, respectively, as permitted under Section 409A and proposed Treasury Regulation ss. 1.409-3(d) (because such payment was not administratively practicable due to events beyond the control of the Executive) and, as such, shall be made as soon as administratively practicable (but in no event shall it be made later than the end of the first calendar year in which the payment becomes administratively practicable). 10. Non-exclusivity of Rights. Except as otherwise specifically provided, nothing in this Agreement will prevent or limit the Executive's continued or future participation in any benefit, incentive, or other plan, practice, or program provided by the Corporation and its affiliates and for which the Executive may qualify. Any amount of vested benefit or any amount to which the Executive is otherwise entitled under any plan, practice, or program of the Corporation will be payable in accordance with the plan, practice, or program, except as specifically modified by this Agreement. 11. No Obligation To Seek Other Employment. The Executive will not be obligated to seek other employment or to take other action to mitigate any amount payable to him under this Agreement and, except as provided in Section 8(f), amounts owed to him hereunder shall not be reduced by amounts he may receive from another employer. 13 12. Confidentiality. During the course of his employment, the Executive will have access to confidential information relating to the lines of business of the Corporation, its trade secrets, marketing techniques, technical and cost data, information concerning customers and suppliers, and other valuable and confidential information relating to the business operations of the Corporation not generally available to the public (the "Confidential Information"). The parties hereby acknowledge that any unauthorized disclosure or misuse of the Confidential Information could cause irreparable damage to the Corporation. The parties also agree that covenants by the Executive not to make unauthorized use or disclosures of the Confidential Information are essential to the growth and stability of the business of the Corporation. Accordingly, the Executive agrees to the confidentiality covenants set forth in this Section. The Executive agrees that, except as required by his duties with the Corporation as he reasonably determines or as authorized by the Corporation in writing, he will not use or disclose to anyone at any time, regardless of whether before or after the Executive ceases to be employed by the Corporation, any of the Confidential Information obtained by him in the course of his employment with the Corporation. The Executive shall not be deemed to have violated this Section 12 by disclosure of Confidential Information that at the time of disclosure (a) is publicly available or becomes publicly available through no act or omission of the Executive, or (b) is disclosed as required by court order or as otherwise required by law, on the condition that notice of the requirement for such disclosure is given to the Corporation prior to make any disclosure. The Executive agrees that since irreparable damage could result from his breach of the covenants in this Section, in addition to any and all other remedies available to the Corporation, the Corporation will have the remedies of a restraining order, injunction or other equitable relief to enforce the provisions thereof. The Executive consents to jurisdiction in Centre County, Pennsylvania on the date of the commencement of any action for purposes of any claims under this Section. In addition, the Executive agrees that the issues in any action brought under this Section will be limited to claims under this Section, and all other claims or counterclaims under other provisions of this Agreement will be excluded. 13.

For purposes of this Agreement, the following terms have the meanings given to them below: (a) "Affiliate" means any joint venture, partnership or subsidiary now or hereafter directly or indirectly owned or controlled by the Corporation. For purposes of clarification, an entity shall not be deemed to be indirectly or directly owned or controlled by the Corporation solely by reason of the ownership or control of such entity by shareholders of the Corporation.

Successors. This Agreement is personal to the Executive and may not be assigned by the Executive other than by will or the laws of descent and distribution. This Agreement will inure to the benefit of and be enforceable by the Executive's legal representatives or successors in interest. Notwithstanding any other provision of this Agreement, the Executive may designate a successor or successors in interest to receive any amounts due under this Agreement after the Executive's death. If he has not designated a successor in interest, payment of benefits under this Agreement will be made to his spouse, if surviving, and if not surviving, to his estate. A designation of a successor in interest must be made in writing, signed by the Executive, and delivered to the Employer pursuant to Section 18. Except as otherwise provided in this agreement, if the Executive has not designated a successor in interest, payment of benefits under this Agreement will be made to the Executive's estate. This Section will not supersede any designation of beneficiary or successor in interest made by the Executive or provided for under any other plan, practice, or program of the Employer.
