As of the Effective Time, by virtue of the Merger and without any action on the part of Acquisition, Petroglyph or the holders of any shares of Petroglyph Common Stock or any other capital stock of Petroglyph: (a) Common Stock of Acquisition. Each share of Common Stock, par value $.01 per share, of Acquisition (the "Acquisition Common Stock") that shall be issued and outstanding immediately before the Effective Time shall be converted into and become one share of the Common Stock, par value $.01 per share, of the Surviving Corporation (the "Surviving Corporation Common Stock").

Subject to Sections 1.6(c), 1.6(d), 1.6(e), 1.7 and 1.8, each share of Petroglyph Common Stock that is issued and outstanding immediately before the Effective Time shall be converted into and become the right to receive the sum (the "Merger Consideration") of $2.85 in cash and, when so converted, shall automatically be canceled and retired and shall cease to exist, and each holder of a certificate representing any such shares of Petroglyph Common Stock shall, to the extent such certificate represents such shares, cease to have any rights with respect thereto, except the right to receive the Merger Consideration allocable to the shares formerly represented by such certificate upon surrender of such certificate in accordance with Section 1.9. (c) Cancellation of Treasury Stock. Each share of Petroglyph Common Stock that shall be owned immediately before the Effective Time by Petroglyph or any Subsidiary (as hereinafter defined) of Petroglyph that constitutes treasury stock in the hands of the holder thereof, shall be canceled and retired and shall cease to exist, and no consideration shall be delivered in exchange therefor, and each holder of a certificate representing any such shares shall cease to have any rights with respect thereto. The term "Subsidiary" means any corporation, joint venture, partnership, limited liability company or other entity of which Petroglyph, directly or indirectly, owns or controls capital stock (or other equity interests) -2- 6 representing more than fifty percent of the general voting power of such entity under ordinary circumstances.

Section 1.7. Dissenting Shares (a) Notwithstanding anything in this Agreement to the contrary, shares of Petroglyph Common Stock outstanding immediately before the Effective Time and held by a holder who shall have demanded and perfected such holder's right to appraisal of such shares in accordance with Section 262 of the DGCL ("Dissenting Shares") shall not be converted into or represent the right to receive the Merger Consideration, but the holder thereof shall instead be entitled to such rights as are afforded under the DGCL with respect to such holder's Dissenting Shares, unless such holder shall fail to perfect or shall withdraw or otherwise lose such holder's right to appraisal. (b) If any holder of shares of Petroglyph Common Stock who shall demand appraisal of such holder's shares pursuant to the DGCL shall fail to perfect or shall withdraw or otherwise lose such holder's right to appraisal, at the later of the Effective Time or upon the occurrence of such event, the Dissenting Shares of such holder shall be converted into and represent the right to receive the Merger Consideration, without interest thereon, in accordance with Section 1.6(b). (c) Petroglyph shall give IIIX and, after its formation, Acquisition (i) prompt notice of any written demand for appraisal or payment of the fair value of any shares of Petroglyph Common Stock, withdrawals of such demands, and any other instruments served pursuant to the DGCL received by Petroglyph and (ii) the opportunity to direct all negotiations and proceedings with respect to demands for appraisal under the DGCL. Petroglyph shall not voluntarily make any payment with respect to any demand for appraisal and shall not, except with the prior written consent of IIIX or Acquisition, settle or offer to settle any such demands.

Petroglyph shall take all actions necessary to provide that each outstanding and unexercised stock option or stock appreciation right (collectively, the "Petroglyph Options") granted under -3- 7 the Petroglyph Incentive Plan, whether or not exercisable or vested, shall be terminated in accordance with the Petroglyph Incentive Plan prior to the Effective Time. Section 1.9. Exchange of Certificates. (a) Exchange Agent. Before the Effective Time, Petroglyph shall appoint a bank or trust company to act as exchange agent (the "Exchange Agent") for the payment of the Merger Consideration. As of the Effective Time, Acquisition shall deposit with the Exchange Agent, for the benefit of the holders of shares of Petroglyph Common Stock, for exchange in accordance with this Section 1.9, the aggregate amount of cash payable pursuant to Section 1.6(b) hereof in exchange for outstanding shares of Petroglyph Common Stock (the "Exchange Fund"). (b) Exchange Procedures. Promptly after the Effective Time, the Exchange Agent shall mail to each holder of record of a certificate or certificates, which immediately before the Effective Time shall have represented outstanding shares of Petroglyph Common Stock, whose shares shall have been converted into the right to receive cash pursuant to Section 1.6(b), a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the certificates representing such shares of Petroglyph Common Stock shall pass, only upon delivery of the certificates representing such shares of Petroglyph Common Stock to the Exchange Agent and shall be in such form and have such other provisions not inconsistent with this Agreement as the Exchange Agent may reasonably specify), and instructions for use in effecting the surrender of the certificates representing such shares of Petroglyph Common Stock, together with a duly executed (if required) letter of transmittal, in exchange for the Merger Consideration. Upon surrender to the Exchange Agent of a certificate or certificates formerly representing shares of Petroglyph Common Stock and acceptance thereof by the Exchange Agent, the holder thereof shall be entitled to the amount of cash into which the number of shares of Petroglyph Common Stock formerly represented by such certificate or certificates surrendered shall have been converted pursuant to this Agreement. The Exchange Agent shall accept such certificates upon compliance with such reasonable terms and conditions as the Exchange Agent may impose to effect an orderly exchange thereof in accordance with normal exchange practices. After the Effective Time, there shall be no further transfer on the records of Petroglyph or its transfer agent of certificates representing shares of Petroglyph Common Stock and, if such certificates shall be presented to Petroglyph for transfer, they shall be canceled against delivery of the Merger Consideration allocable to the shares of Petroglyph Common Stock represented by such certificate or certificates. If any Merger Consideration is to be remitted to a name other than that in which the certificate for the Petroglyph Common Stock surrendered for exchange is registered, it shall be a condition of such exchange that the certificate so surrendered shall be properly endorsed, with signature guaranteed, or otherwise in proper form for transfer and that the person requesting such exchange shall pay to Petroglyph, or its transfer agent, any transfer or other taxes required by reason of the payment of the Merger Consideration to a name other than that of the registered holder of the certificate surrendered, or establish to the satisfaction of Petroglyph or its transfer agent that such tax shall have been paid or shall not be applicable. Until surrendered as contemplated by this Section 1.9, each certificate for shares of Petroglyph Common Stock shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender the Merger -4- 8 Consideration allocable to the shares represented by such certificate as contemplated by Section 1.6(b). No interest will be paid or will accrue on any amount payable as Merger Consideration. (c) No Further Ownership Rights in Petroglyph Stock. The Merger Consideration paid upon the surrender for exchange of certificates formerly representing shares of Petroglyph Common Stock in accordance with the terms of this Section 1.9 shall be deemed to have been paid in full satisfaction of all rights pertaining to the shares of Petroglyph Common Stock formerly represented by such certificates. (d) Termination of Exchange Fund. Any portion of the Exchange Fund (including any interest and other income received by the Exchange Agent in respect of all such funds) that shall remain undistributed to the holders of the certificates formerly representing shares of Petroglyph Common Stock for six months after the Effective Time shall be delivered to the Surviving Corporation, upon demand, and any holders of shares of Petroglyph Common Stock before the Merger who have not theretofore complied with this Section 1.9 shall thereafter look only to the Surviving Corporation, and only as general creditors thereof, for payment of their claim for Merger Consideration to which such holders may be entitled. (e) No Liability. No party to this Agreement shall be liable to any Person (as hereinafter defined) in respect of any amount from the Exchange Fund delivered to a public official pursuant to any applicable abandoned property, escheat or similar law. The term "Person" means any individual, entity, corporation, partnership, trust or unincorporated organization or any government or any agency or political subdivision thereof. (f) Lost Certificates. If any certificate or certificates formerly representing shares of Petroglyph Common Stock shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such certificate or certificates to be lost, stolen or destroyed, and if required by the Surviving Corporation, the posting by such Person of a bond in such amount as the Surviving Corporation may reasonably require as indemnity against any claim that may be made against it with respect to such certificate, the Exchange Agent shall issue in exchange for such lost, stolen or destroyed certificate the Merger Consideration deliverable in respect thereof as determined in accordance with this Section 1.9. (g) Withholding Rights. The Surviving Corporation and the Exchange Agent shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any holder of shares of Petroglyph Common Stock such amounts as the Surviving Corporation or the Exchange Agent shall be required to deduct and withhold under the United States Internal Revenue Code of 1986, as amended, or any provision of state, local or foreign tax law with respect to the making of such payment. To the extent that amounts are so withheld by the Surviving Corporation or the Exchange Agent, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the shares of Petroglyph Common Stock in respect of which such deduction and withholding was made by the Surviving Corporation or the Exchange Agent. -5- 9 Section 1.10. Proxy Statement and Schedule 13E-3. (a) Petroglyph shall prepare, in consultation with IIIX, the Proxy Statement on Schedule 14A under the Securities Exchange Act of 1934 (the "Exchange Act") (the "Proxy Statement") to be distributed to holders of the Petroglyph Common Stock for the purpose of soliciting proxies for use at the annual or special meeting of stockholders of Petroglyph (the "Stockholders Meeting") at which the adoption of this Agreement and the approval of the transactions contemplated thereby shall be sought.

The Proxy Statement shall, as of its date, comply as to form in all material respects with all applicable laws, including the Exchange Act, and the rules and regulations thereunder. Petroglyph shall not mail, amend or supplement the Proxy Statement unless the Proxy Statement or any amendment or supplement thereof shall be satisfactory in content to IIIX in the exercise of its reasonable judgment. (c) As soon as practicable after the date of this Agreement, IIIX and Petroglyph shall file with the SEC, and shall use their reasonable best efforts to cause any of their respective affiliates engaging in this transaction to file with the SEC, a Rule 13e-3 Transaction Statement on Schedule 13E-3 under the Exchange Act (the "Schedule 13E-3 Transaction Statement") with respect to the Merger. Each of the parties hereto shall agree to use its reasonable best efforts to cooperate and to provide each other with such information as any of such parties may reasonably request in connection with the preparation of the Proxy Statement and the Schedule 13E-3 Transaction Statement.

If, at any time after the Effective Time, any further action is necessary or desirable -6- 10 to carry out the purposes of this Agreement or to vest the Surviving Corporation with full title to all properties, assets, rights, approvals, immunities and franchises of either Petroglyph or Acquisition, the proper officers and directors of each corporation that is a party to this Agreement shall take all such necessary action. The parties hereto shall use their respective best efforts to challenge any action brought against any of the parties hereto seeking a temporary restraining order or preliminary or permanent injunctive relief which would prohibit, or materially interfere with, the consummation of the transactions contemplated by this Agreement.

On or before the date hereof, the Special Committee (i) determined that the Merger is fair to and in the best interest of the stockholders of Petroglyph other than IIIX (the "Public Stockholders") and (ii) recommended that the Board of Directors of Petroglyph approve this Agreement and such transactions.

Acquisition will be incorporated solely for the purpose of merging with and into Petroglyph and taking action incident thereto. Except for obligations or liabilities incurred in connection with the transactions contemplated by this Agreement or in connection with its organization, at the Effective Time Acquisition will not have incurred any obligations or liabilities or engaged in any business activities of any kind. Section 3.2. Authorization.

This Agreement has been duly executed and delivered by IIIX and, assuming the due authorization, execution and delivery hereof by Petroglyph, constitutes the valid and binding obligation of IIIX, enforceable against IIIX in accordance with its terms, except as such enforceability may be limited by applicable bankruptcy, insolvency, reorganization, or similar laws affecting creditors' rights generally or by general equitable principles. Upon consummation of the Assignment (as hereinafter defined), assuming the due authorization, execution and delivery hereof by Petroglyph, this Agreement will constitute the valid and binding obligation of Acquisition, enforceable against Acquisition in accordance with its terms, except as such enforceability may be limited by applicable bankruptcy, insolvency, reorganization, or similar laws affecting creditors' rights generally or by general equitable principles. Section 3.3. Brokers and Intermediaries. IIIX has not, and Acquisition will not have, employed any broker, finder, advisor or intermediary in connection with the transactions contemplated by this Agreement which would be entitled to a broker's, finder's, or similar fee or commission in connection therewith or upon the consummation thereof. Any such fees shall be the liability of IIIX or Acquisition. Section 3.4. Proxy Statement. None of the information to be supplied by IIIX or Acquisition for inclusion in the Proxy Statement will, at the time of the mailing of the Proxy Statement and any amendments or supplements thereto, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they are made, not misleading.

Petroglyph shall give prompt notice to IIIX and Acquisition, and IIIX and Acquisition shall give prompt notice to Petroglyph, of (a) the occurrence or non-occurrence of any event the occurrence or non-occurrence of which -11- 15 would be reasonably likely to cause any representation or warranty contained in this Agreement to be untrue or inaccurate in any material respect at or before the Effective Time and (b) any material failure of Petroglyph, or of IIIX or Acquisition, as the case may be, to comply with or satisfy any covenant, condition or agreement to be complied with or satisfied by it hereunder; provided, however, that the delivery of any notice pursuant to this Section 4.3 shall not limit or otherwise affect the remedies available hereunder to the party or parties receiving such notice.

(b) IIIX or the Surviving Corporation shall maintain in effect for six years from the Effective Time policies of directors' and officers' liability insurance containing terms and conditions which shall not be less advantageous to the insured (as defined under the Petroglyph Insurance Policies (as hereinafter defined)) than any such policies of Petroglyph currently in effect on the date of this Agreement (the "Petroglyph Insurance Policies"), with respect to matters occurring before the Effective Time, to the extent available, and having the maximum available coverage under any such Petroglyph Insurance Policies; provided, that in no event shall the Surviving Corporation be required to pay annual premiums for insurance under this Section 4.3(b) in excess of 200% of the annual premiums currently paid by Petroglyph and provided further, however, that if the annual premiums for such insurance coverage exceed 200% of the annual premiums currently paid by Petroglyph, the Surviving Corporation shall be obliged to obtain a policy with the greatest coverage that can be obtained for premiums that are 200% of the annual premiums currently paid by Petroglyph.
