(a)           Each share of Plains Energy Common Stock issued and outstanding immediately prior to the Effective Time (other than shares to be extinguished pursuant to this Section 2.2 and the Dissenting Shares as defined in Section 2.5 below) shall be cancelled and extinguished and automatically converted into the right to receive 0.86836131 of one (1) fully paid and non-assessable share of ante4 Common Stock. ante4 shall issue to each holder of Plains Energy Common Stock (other than holders of shares extinguished pursuant to this Section 2.2 and Dissenting Shares) certificates evidencing the number of shares of ante4 Common Stock determined in accordance with the foregoing, with each fractional share rounded up to the nearest whole share.

(b)           Warrants to purchase an aggregate of 5,400,000 shares of Plains Energy Common Stock that are issued and outstanding immediately prior to the Effective Time (the “Warrants”) will be exchanged into warrants to purchase 0.86836131 of one (1) share of ante4 Common Stock for each share of Plains Energy Common Stock represented by the Warrants immediately prior to the Effective Time, exercisable at $0.98 per share, with each fractional warrant share rounded up to the nearest whole share (the “ante4 Warrants”).  The ante4 Warrants will be substantially in the form attached hereto as Exhibit B.

(c)           A total of 540,000 restricted shares of Plains Energy Common Stock outstanding immediately prior to the Effective Time issued pursuant to restricted stock award agreements (the “Plains Energy Restricted Stock”) will be exchanged into 0.86836131 of one (1) restricted share of ante4 Common Stock for each share of Plains Energy Restricted Stock outstanding immediately prior to the Effective Time, with each fractional share rounded up to the nearest whole share, subject to the vesting, risk of forfeiture and other conditions set forth in the form of restricted stock agreement attached hereto as Exhibit C (the “Restricted Stock Agreements”). The certificates representing such restricted shares of ante4 Common Stock will accordingly be marked with appropriate legends.

7

(e)           Each share of common stock, $0.001 par value per share, of PAC issued and outstanding immediately prior to the Effective Time will be automatically converted into one validly issued, fully paid and nonassessable share of common stock of the Surviving Company; and

(f)            All shares of ante4 Common Stock issued upon the surrender of and exchange for shares of Plains Energy Stock in accordance with the above terms and conditions shall be deemed to have been issued and paid in full satisfaction of all rights pertaining to such shares of Plains Energy Stock.

2.3                                 Rights of Holders of Plains Energy Capital Stock.

(a)           From and after the Effective Time and until surrendered for exchange, each outstanding stock certificate that immediately prior to the Effective Time represented shares of Plains Energy Stock (except Dissenting Shares and shares cancelled or extinguished pursuant to Section 2.2) shall be deemed for all purposes, to evidence ownership of and to represent the number of whole shares of ante4 Common Stock into which such shares of Plains Energy Stock shall have been converted pursuant to Section 2.2(a) above.  The record holder of each such outstanding certificate representing shares of Plains Energy Stock, shall, after the Effective Time, be entitled to vote the shares of ante4 Common Stock into which such shares of Plains Energy Stock shall have been converted on any matters on which the holders of record of the ante4 Common Stock, as of any date subsequent to the Effective Time, shall be entitled to vote.

(a)           After the Effective Time, each holder of certificate(s) theretofore evidencing outstanding shares of Plains Energy Stock (except Dissenting Shares and shares cancelled or extinguished pursuant to Section 2.2) shall, upon surrender of such certificate(s) to the registrar or transfer agent for ante4 Common Stock, be entitled to receive certificates representing the number of whole shares of ante4 Common Stock into which shares of Plains Energy Stock theretofore represented by the certificates so surrendered shall have been converted as provided in Section 2.2 hereof.  ante4 shall not be obligated to deliver certificates representing shares of ante4 Common Stock, to which any holder of shares of Plains Energy Stock is entitled, until such holder surrenders the certificate(s) representing such Plains Energy Stock.  Upon surrender, each certificate evidencing Plains Energy Stock shall be canceled.  If there is a transfer of Plains Energy Stock ownership which is not registered in the transfer records of Plains Energy, a certificate representing the proper number of shares of ante4 Common Stock may be issued to a

8

Person other than the Person in whose name the certificate so surrendered is registered if: (x) upon presentation to the Secretary of ante4, such certificate shall be properly endorsed or otherwise be in proper form for transfer, (y) the Person requesting such transfer shall pay any transfer or other Taxes required by reason of the issuance of shares of or certificates representing shares of ante4 Common Stock to a Person other than the registered holder of such certificate or establish to the reasonable satisfaction of ante4 that such Tax has been paid or is not applicable, and (z) the issuance of such shares of or certificates representing shares of ante4 Common Stock shall not, in the sole discretion of ante4, violate the requirements of Section 4(2) of the Securities Act with respect to the private placement of ante4 Common Stock that will result from the Merger.

(b)           Any shares of ante4 Common Stock issued in the Merger will not be transferable except (1) pursuant to an effective registration statement under the Securities Act or (2) upon receipt by ante4 of a written opinion of counsel reasonably satisfactory in form and substance to ante4 to the effect that the proposed transfer is exempt from the registration requirements of the Securities Act and relevant state securities laws.  Restrictive legends will be placed on all certificates representing shares of ante4 Common Stock issued in the Merger, substantially as follows:

NO TRANSFER, SALE, ASSIGNMENT, PLEDGE, HYPOTHECATION OR OTHER DISPOSITION OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE MAY BE MADE EXCEPT (A) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND THE RULES AND REGULATIONS IN EFFECT THEREUNDER AND ALL APPLICABLE STATE SECURITIES OR “BLUE SKY” LAWS (SUCH FEDERAL AND STATE LAWS, THE “SECURITIES LAWS”) OR (B) IF THE COMPANY HAS BEEN FURNISHED WITH AN OPINION OF COUNSEL FOR THE HOLDER, WHICH OPINION AND COUNSEL SHALL BE REASONABLY SATISFACTORY TO THE COMPANY TO THE EFFECT THAT SUCH TRANSFER, SALE, ASSIGNMENT, PLEDGE, HYPOTHECATION OR OTHER DISPOSITION IS EXEMPT FROM THE REGISTRATION OR SIMILAR REQUIREMENTS OF THE SECURITIES LAWS.

(c)           In the event any certificate for shares of Plains Energy Stock shall have been lost, stolen or destroyed, ante4 shall issue in exchange for such lost, stolen or destroyed certificate, upon the making of a sworn affidavit of that fact by the holder thereof, one or more certificates representing such shares of ante4 Common Stock as provided herein; provided, however, that ante4, in its discretion and as a condition precedent to the issuance of such certificates, may require the holder of the shares represented by such lost, stolen or destroyed certificate to deliver a bond in such sum as it may direct as indemnity against any claim that may be made against ante4 or any other party with respect to the certificate alleged to have been lost, stolen or destroyed.

(b)           Any payments in respect of Dissenting Shares will be deemed made by the Surviving Company.

Each party will use all reasonable efforts and will cooperate with the other party in taking any other actions necessary to obtain such regulatory or other approvals and consents at the earliest practicable time, including participating in any required hearings or proceedings. Subject to the terms and conditions herein provided, each party will use all reasonable efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things necessary, proper or advisable under applicable law and regulations to consummate and make effective as promptly as practicable the Merger and the other transactions contemplated by this Agreement.

If any such press release or public announcement is so required, the party making such disclosure shall consult with the other party prior to making such disclosure, and the parties shall use all reasonable efforts, acting in good faith, to agree upon a text for such disclosure which is satisfactory to both parties.

5.5                                 Registration Rights with Respect to ante4 Common Stock.

(a)                                    On or prior to the fifth (5th) business day following the Closing Date, ante4 shall use commercially reasonable efforts to prepare and file with the SEC a registration statement covering the resale of all Registrable Securities for an offering to be made on a continuous basis pursuant to Rule 415 (the “Initial Registration Statement”); provided, however, that if the 5th business day following the Closing Date falls on a day that the SEC is closed for business, such deadline shall be extended to the next business day on which the SEC is open for business.  The Initial Registration Statement shall be on Form S-1.  Notwithstanding the registration obligations set forth in this Section 5.5, in the event the SEC informs ante4 that all of the Registrable Securities cannot, as a result of the application of Rule 415, be registered for resale on a single registration statement, the Company agrees to promptly (i) inform each of the Holders thereof; (ii) permit one (1) counsel of such Holders (to be chosen by a majority of the Holders, and at all such Holders expense) to review and participate in discussions regarding ante4’s response to the SEC regarding the application of 415 to the Initial Registration Statement, (iii) use its best efforts to file amendments to the Initial Registration Statement as required by the SEC and/or (iv) if required by the SEC, withdraw the Initial Registration Statement and file a new registration statement (a “New Registration Statement”), in either case covering the maximum number of Registrable Securities permitted to be registered by the SEC on Form S-1 or such other form available to register for resale the Registrable Securities.  In the event ante4 amends the Initial Registration Statement or files a New Registration Statement, as the case may be, under clauses (i) or (ii) above, ante4 will use its best efforts to file with the SEC, as promptly as allowed by the SEC or staff guidance provided to ante4 or to registrants of securities in general, one or more registration statements on Form S-1 or such other form available to register for resale those Registrable Securities that were not registered for resale on the Initial Registration Statement, as amended, or the New Registration Statement.

(b)                                   ante4 shall use its best efforts to cause each registration statement to be declared effective by the SEC as soon as practicable and shall use its best efforts to keep each registration statement continuously effective under the Securities Act until the earlier of (i) such time as all of the Registrable Securities covered by such registration statement have been publicly sold by the Holders, (ii) the date that all Registrable Securities covered by such registration statement may be sold without restriction pursuant to Rule 144 of the Securities Act, as determined by counsel to the Surviving Company pursuant to a written opinion letter to such effect, addressed and acceptable to the Transfer Agent and the affected Holders, or (iii) the date that is one (1) year from the Closing Date.  ante4 shall ensure that each registration statement (including any amendments or supplements thereto and prospectuses contained therein) shall not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein, or necessary to make the statements therein (in the case of prospectuses, in the light of the circumstances in which they were made) not misleading.  Each registration statement shall also cover, to the extent allowable under the Securities Act and the rules promulgated thereunder

32

(including Rule 416), such indeterminate number of additional shares of ante4’s common stock resulting from stock splits, stock dividends or similar transactions with respect to the Registrable Securities. Notwithstanding any other provision of this Section 5.5, ante4 may at any time, abandon or delay any registration commenced ante4 if the Board determines in good faith that such abandoning or delay is reasonably necessary to comply with the requirements of the SEC.  In the event of such an abandonment, the ante4 shall not be required to continue registration of shares requested by the Holder for inclusion, the Holder shall retain the right to request inclusion of shares as set forth above and the withdrawn registration shall not be deemed to be a registration request for the purposes of Section 5.5(c) below.

(c)                                  Each Holder shall have the right to request inclusion of any of its Registrable Securities in a registration statement as described in this Section 5.5, but shall only be able to make one such request.  Notwithstanding anything to the contrary contained in this Section 5.5, all registration rights hereunder shall expire on the one (1) year anniversary of the Closing Date.
