Indemnification. (a) Indemnification by the Sellers. 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 Sellers' obligations to indemnify hereunder, be deemed "Sellers") shall indemnify (i) Buyer and each of the directors, officers, employees and Affiliates of Buyer, and each of their successors and assigns, (ii) Damson and (iii) Gaines (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 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. As more fully provided in Section 8(a) of this Agreement, 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. (b) Indemnification by the Buyer. The Buyer shall indemnify (i) 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 and (ii) the Acquirers (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 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. (c) Sole and Exclusive Remedy. Subject to the last sentence of this Section 7(c), 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 7(a) hereof shall be pursuant to this Section 7, and 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 7(b) hereof shall be pursuant to this Section 7. The foregoing shall not be construed to be a limitation of or in restriction of any rights of the Parties that may exist with respect to indemnification, contribution or other remedies pursuant to the terms of the Mutual Release Agreement and the Mutual Non-Disparagement Agreement entered into contemporaneously herewith. - 6 - (d) 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 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. (e) 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. 8. Miscellaneous. (a) Nature of Certain Obligations. The covenants of each of the Sellers to the Buyer, Damson and Gaines contained in this Agreement and the representations and warranties of each of the Sellers in Section 4 above (excluding as to Shaner and Hulburt, who shall have no liability therefor) are - 7 - several obligations, representations and warranties and are made by each Seller with respect only to that Seller and its business and affairs. This means that such particular Seller making the representation, warranty, or covenant (and no other Seller) will be solely responsible to the extent provided in Section 7 above for any actions, suits, proceedings, hearings, investigations, charges, complaints, claims, demands, injunctions, judgments, orders, decrees, rulings, damages, dues, penalties, fines, costs, amounts paid in settlement, liabilities, obligations, taxes, liens, losses, expenses, and fees, including court costs and reasonable attorneys' fees and expenses that the Buyer may suffer as a result of any breach thereof. (b) Press Releases and Public Announcements. Except as provided in Section 3(c) of this Agreement, no Party shall issue any press release or make any public announcement relating to the subject matter of this Agreement without the prior written approval of the other Parties; provided, however, that any Party may make any public disclosure it believes in good faith is required by applicable law or any listing or trading agreement concerning its publicly-traded securities (in which case the disclosing Party will use its reasonable best efforts to advise the other Parties prior to making such disclosure). (c) Remedies. The Parties hereto agree that irreparable damage would occur in the event any provision of this Agreement were not performed in accordance with the terms hereof and that the Parties shall be entitled to equitable relief, including injunction and specific performance (and attorneys' fees in connection with seeking such relief), as a remedy for any such breach. Such remedies shall not be deemed to be the exclusive remedies for a breach by the Board but shall be in addition to all other remedies available at law or equity to the Parties. (d) Entire Agreement. This Agreement (including the documents referred to herein) constitutes the entire agreement between the Parties and supersedes any prior understandings, agreements, or representations by or among the Parties, written or oral, to the extent they relate in any way to the subject matter hereof.

("we" or the "Company") entered into a Mutual Termination Agreement (the "Termination Agreement") with Rex Energy Operating Corp. ("Rex Energy") and certain of its affiliates (collectively, the "Rex Parties"), pursuant to which we and the Rex Parties mutually terminated (i) that certain purchase agreement between us dated January 16, 2006 (the "Purchase Agreement") and (ii) that certain stock agreement dated January 16, 2006 (as amended on March 10, 2006, the "Stock Agreement"). For a summary of the transactions previously contemplated by the Purchase Agreement and the Stock Agreement, reference is made to our Report on Form 8-K, filed with the SEC on January 17, 2006 and our Annual Report on Form 10-KSB filed on March 31, 2006. Pursuant to the Termination Agreement, a copy of which is filed as Exhibit 99.1 hereto, we have also entered into a Mutual Release Agreement (the "Release Agreement") and a Mutual Non-Disparagement Agreement (the "Non-Disparagement Agreement") with the Rex Parties, copies of which are filed as Exhibits 99.2 and 99.3, respectively, hereto. Pursuant to the Termination Agreement, the Rex Parties surrendered for cancellation, 12,069,250 shares of our common stock, previously issued to them pursuant to the Stock Agreement. After giving effect to the cancellation of such shares, we have 30,271,818 shares of common stock outstanding as of the date hereof and options, warrants and convertible promissory notes to purchase up to an additional 19,871,590 shares of our common stock. Pursuant to the Release Agreement, we and the Rex Parties have agreed to release and hold each other harmless from all Claims stemming from Controversies (each as defined in the Release Agreement) arising out of our dealings with one another. Nothing in the Termination Agreement, the Release Agreement or the Non-Disparagement Agreement effects our rights with respect to the New Albany-Indiana, LLC, a Delaware limited liability company in which we own a 50% non-managed membership interest ("New Albany"). As previously disclosed, New Albany holds an undivided 48.75% working interest (40.7% net revenue interest) in (i) certain oil, gas and mineral leases covering approximately 80,000 acres in the State of Indiana and (ii) all of the rights of Aurora Energy Ltd. ("Aurora") under a certain Farmout Agreement with a third party. In addition, New Albany holds an option from Aurora, exercisable by New Albany until August 1, 2007, to acquire a fifty percent (50%) working interest in any and all acreage leased or acquired by Aurora or its affiliates in additional counties in Indiana (currently estimated to be 50,000 acres), at a fixed price of $25 per acre. New Albany also holds a 45% working interest in certain oil, gas and mineral leases acquired from Source Rock Resources, Inc., covering approximately 21,000 acres in Knox and Sullivan Counties in Indiana, which the Company believes contain New Albany Shale formation stratum. The Rex Parties continue to own the other 50% membership interest in New Albany, and Rex Energy Wabash, LLC is the managing member of New Albany and manages its day-to-day operations.
