The date upon which the Closing occurs is herein referred to as the “Closing Date.”

2.3 Transactions to be Effected at the Closing.

(a) Seller shall be entitled to receive immediately 8,785,819 of the Purchase Price Shares (the “Initial Purchase Price Shares”); the remaining 1,500,000 of the Purchase Price Shares (the “Escrow Purchase Price Shares”), shall be deposited in escrow pursuant to Section 2.3(d) and shall be held and disposed of in accordance with the terms of the Escrow Agreement.

(b) At the Closing, Buyer shall deliver to Seller (i) an original certificate or certificates representing the Initial Purchase Price Shares, (ii) all other documents, instruments or certificates required to be delivered by Buyer at or prior to the Closing pursuant to this Agreement, and (iii) the Estimated Closing Cash Amount, to be paid by wire transfer of immediately available funds to an account designated in writing by Seller.

Buyer and Seller shall make available to the Independent Expert all relevant books and records and other items reasonably requested by the Independent Expert. The parties shall request that the Independent Expert deliver to Buyer and Seller, as promptly as practicable but in no event later than 45 days after its retention, a report which sets forth its resolution of the disputed items and its calculation of the Closing Cash Amount; provided that in no event shall the Closing Cash Amount as determined by the Independent Expert be less than Buyer’s calculation of the Closing Cash Amount nor more than Seller’s calculation of the Closing Cash Amount set forth in the Notice of Objection. The decision of the Independent Expert shall be final, conclusive and binding on the parties. The costs and expenses of the Independent Expert shall be allocated between the parties based upon the percentage which the portion of the contested amount not awarded to each party bears to the amount actually contested by such party.

All Taxes owed by any Seller Company or any member of a Relevant Group in respect of any Taxes payable or asserted to be payable by or in respect of the Acquired Company or any of its Subsidiaries (whether or not shown on any Tax Return) have been timely paid.

(a) Seller is acquiring the Purchase Price Shares for investment for its own account and not with the view to, or for resale in connection with, any distribution thereof. Seller understands and acknowledges that the Purchase Price Shares have not been registered under the Securities Act or any state or foreign securities laws, by reason of a specific exemption from the registration provisions of the Securities Act and applicable state and foreign securities laws, which depends upon, among other things, the bona fide nature of the investment intent as expressed herein. Seller further represents that it does not have any contract, undertaking, agreement or arrangement with any Person to sell, transfer or grant participation to any third person with respect to any of the Purchase Price Shares.

(b) Seller understands that an active public market for Buyer Common Stock may not now exist and that there may never be an active public market for the Purchase Price Shares acquired under this Agreement.

(d) Seller, if a non-U.S. Person, agrees that it is acquiring the Shares in an offshore transaction pursuant to Regulation S and hereby represents to Buyer as follows:

(i) Seller is outside the United States when receiving and executing this Agreement;

(ii) Seller has not acquired the Shares as a result of, and will not itself engage in, any “directed selling efforts” (as defined in Regulation S) in the United States in respect of the Shares which would include any activities undertaken for the purpose of, or that could reasonably be expected to have the effect of, conditioning the market in the United States for the resale of the Shares; provided, however, that Seller may sell or otherwise dispose of the Shares pursuant to registration of the Shares under the Securities Act and any applicable state and provincial securities laws or under an exemption from such registration requirements and as otherwise provided herein;

(iii) Seller understands and agrees that offers and sales of any of the Shares prior to the expiration of a period of one year after the Closing Date (the “Distribution Compliance Period”), shall only be made in compliance with the safe harbor provisions set forth in Regulation S, pursuant to the registration provisions of the Securities Act or an exemption therefrom, and that all offers and sales after the Distribution Compliance Period shall be made only in compliance with the registration provisions of the Securities Act or an exemption therefrom, and in each case only in accordance with all applicable securities laws; and

(iv) Seller understands and agrees not to engage in any hedging transactions involving the Shares prior to the end of the Distribution Compliance Period unless such transactions are in compliance with the Securities Act.

(v) Seller hereby represents that it has satisfied itself as to the full observance of the laws of its jurisdiction in connection with any invitation to subscribe for the Shares or any use of this Subscription Agreement, including: (a) any applicable legal requirements incumbent upon Seller within its jurisdiction for the purchase of the Shares; (b) any foreign exchange restrictions applicable to such purchase; (c) any governmental or other consents that Seller may need to obtain; and (d) the income tax and other tax consequences, if any, that may be relevant to the purchase, holding, redemption, sale or transfer of the Shares.

(e) Seller represents that neither it nor, to its knowledge, any Person or entity controlling, controlled by or under common control with it, nor any Person having a beneficial interest in it, nor any Person on whose behalf Seller is acting: (i) is a Person listed in the Annex to Executive Order No. 13224 (2001) issued by the President of the United States (Executive Order Blocking Property and Prohibiting Transactions with Persons Who Commit, Threaten to Commit, or Support Terrorism); (ii) is named on the List of Specially Designated Nationals and Blocked Persons maintained by the U.S. Office of Foreign Assets Control; (iii) is a non-U.S. shell bank or is providing banking services indirectly to a non-U.S. shell bank; (iv) is a senior non-U.S. political figure or an immediate family member or close associate of such figure; or (v) is otherwise prohibited from investing in Buyer pursuant to applicable U.S. anti-money laundering, anti-terrorist and asset control laws, regulations, rules or orders (categories (i) through (v), each a “Prohibited Seller”). Seller agrees to provide Buyer, promptly upon request, all information that is reasonably necessary or appropriate to comply with applicable U.S. anti-money laundering, anti-terrorist and asset control laws, regulations, rules and orders. Seller consents to the disclosure to U.S. regulators and law enforcement authorities by Buyer and its affiliates and agents of such information about Seller as is reasonably necessary or appropriate to comply with applicable U.S. anti-money-laundering, anti-terrorist and asset control laws, regulations, rules and orders. Seller acknowledges that if, following its investment in Buyer, Buyer reasonably believes that Seller is a Prohibited Seller or is otherwise engaged in suspicious activity or refuses to promptly provide information that Buyer requests, Buyer has the right or may be obligated to prohibit additional investments, and take any other actions required by Law.

(f) Seller or its duly authorized representative realizes that because of the inherently speculative nature of business activities and investments of the kind contemplated by Buyer, Buyer’s financial position and results of operations may be expected to fluctuate from period to period and will, generally, involve a high degree of financial and market risk that can result in substantial or, at times, even total loss of the value of the Purchase Price Shares.

(g) Seller acknowledges and agrees that Buyer was, at one time, a “shell company” as defined in Rule 12b-2 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

As a result, the restrictive legends on certificates for the Purchase Price Shares set forth below cannot be removed except in connection with an actual sale meeting the foregoing requirements.

(b) The representations in Section 3.32(a) shall not apply to any facilitating or expediting payment to a Government Official, political party, or party official the purpose of which is to expedite or to secure the performance of a routine governmental action by a Government Official, political party, or party official.

Except with respect to Tax Returns described in Section 7.3(a)(iv), if any item of loss or credit of the Acquired Company or any of its Subsidiaries (or successor thereto) for a Post-Cutoff Period is carried back to a Pre-Cutoff Period, is used or otherwise absorbed and results in a refund directly to or an actually recognized reduction of Taxes otherwise payable by a Seller Party, then Seller will, within 10 Business Days following the receipt of any such refund or other final recognition of such Tax benefit, pay the portion of such refund or benefit attributable to such carryback, net of any Taxes imposed on any Seller Party with respect thereto, to the Acquired Company or such Subsidiary of the Acquired Company, as the case may be.

In no event shall Buyer, the Acquired Company or their respective Subsidiaries use any Names after the Closing in any manner or for any purpose different from the use of such Names by the Acquired Company and its Subsidiaries, as the case may be, during the three-year period preceding the Closing Date. “Names” means the Avante Marks or any name, logo or trademark that includes “Avante,” any variation and derivatives thereof and any other logos or trademarks of Seller or its Affiliates after the Closing.

(a) Subject to the limitations set forth in this ARTICLE X, Buyer shall indemnify and defend Seller and its Affiliates and their respective stockholders, members, managers, officers, directors, employees, agents, successors and assigns (the “Seller Indemnitees”) against, and shall hold them harmless from, any and all Losses, net of any insurance premiums obtained or to be obtained, resulting from, arising out of, or incurred by any Seller Indemnitee in connection with, or otherwise with respect to:

10.4 Indemnification Procedures for Third Party Claims.

(a) In the event that an Indemnitee receives notice of the assertion of any claim or the commencement of any Action by a third party in respect of which indemnity may be sought under the provisions of this ARTICLE X (“Third Party Claim”), the Indemnitee shall promptly notify the Indemnitor in writing (“Notice of Claim”) of such Third Party Claim. Failure or delay in notifying the Indemnitor will not relieve the Indemnitor of any liability it may have to the Indemnitee, except and only to the extent that such failure or delay causes actual harm to the Indemnitor with respect to such Third Party Claim. The Notice of Claim shall set forth the amount, if known, or, if not known, an estimate of the foreseeable maximum amount of claimed Losses (which estimate shall not be conclusive of the final amount of such Losses) and a description of the basis for such Third Party Claim.

(b) Subject to the further provisions of this Section 10.4, the Indemnitor will have 60 days (or less if the nature of the Third Party Claim requires) from the date on which the Indemnitor received the Notice of Claim to notify the Indemnitee that the Indemnitor will assume the defense or prosecution of such Third Party Claim and any litigation resulting therefrom with counsel of its choice (reasonably satisfactory to the Indemnitee) and at its sole cost and expense (a “Third Party Defense”). If the Indemnitor assumes the Third Party Defense in accordance with the preceding sentence, the Indemnitor shall be conclusively deemed to have acknowledged that the Third Party Claim is within the scope of its indemnity obligation hereunder and shall hold the Indemnitee harmless from and against the full amount of any Losses resulting therefrom (subject to the terms and conditions of this Agreement). Any Indemnitee shall have the right to employ separate counsel in any such Third Party Defense and to participate therein, but the fees and expenses of such counsel shall not be at the expense of the Indemnitor unless (A) the Indemnitor shall have failed, within the time after having been notified by the Indemnitee of the existence of the Third Party Claim as provided in the first sentence of this paragraph (b), to assume the defense of such Third Party Claim, (B) the employment of such counsel has been specifically authorized in writing by the Indemnitor or (C) under applicable standards of professional conduct, a conflict on any significant issue exists between the Indemnitee and the Indemnitor in respect of the Third Party Claim.

(i) the Third Party Claim seeks, in addition to or in lieu of monetary damages, any injunctive or other equitable relief (except where non-monetary relief is merely incidental to a primary claim or claims for monetary damages;

(ii) the Third Party Claim relates to or arises in connection with any criminal proceeding, action, indictment, allegation or investigation; or

(iii) the Third Party Claim would give rise to Losses which exceed $2,500,000.

(d) Seller will not be entitled to assume the Third Party Defense if the Third Party Claim relates to or arises in connection with any Environmental Action. Buyer shall have the right (i) to defend, conduct and control, with counsel of its choice, any Environmental Action, and (ii) to compromise or settle any Environmental Action, and shall, subject to the limitations contained in this Agreement, be indemnified by Seller, provided that Buyer will not consent to the entry of any judgment or enter into any settlement without the written consent of Seller (such consent not unreasonably be withheld or delayed). In the event that Buyer is required or deems it necessary to perform any Remedial Work in connection with an Environmental Action, or to avoid the initiation of an Environmental Action, whether or not formal proceedings have been initiated or threatened with respect thereto, Buyer shall have the right to commence and thereafter prosecute to completion all such Remedial Work, and shall, subject to the limitations of this Agreement, be indemnified by Seller with respect to any and all Losses incurred in connection therewith, provided that Buyer will not commence or prosecute such Remedial Work without the written consent of Seller (such consent not unreasonably be withheld or delayed). “Remedial Work” means any response action, removal action, remedial action, closure, corrective action, regulatory permitting, monitoring program, risk assessment, deed restriction, sampling program, investigation or other activity required, allowed by or consistent with Environmental Law to clean up, remove, remediate, treat, xxxxx or otherwise address any Hazardous Substance.

(e) If by reason of the Third Party Claim a Lien, attachment, garnishment or execution is placed upon any of the property or assets of the Indemnitee and not promptly caused to be discharged by the Indemnitor, the Indemnitor, if it desires to exercise its right to assume such Third Party Defense, must furnish a satisfactory indemnity bond to obtain the prompt release of such Lien, attachment, garnishment or execution.

(f) If the Indemnitor assumes a Third Party Defense, it will take all steps necessary in the defense, prosecution, or settlement of such claim or litigation. The Indemnitor will not consent to the entry of any judgment or enter into any settlement except with the written consent of the Indemnitee; provided that the consent of the Indemnitee shall not be required if all of the following conditions are met: (i) the terms of the judgment or proposed settlement include as an unconditional term thereof the giving to the Indemnitees by the third party of a release of the Indemnitees from all liability in respect of such Third Party Claim, (ii) there is no finding or admission of (A) any violation of Law by the Indemnitees (or any Affiliate thereof), (B) any violation of the rights of any Person and (C) no effect on any other Action or claims of a similar nature that may be made against the Indemnitees (or any Affiliate thereof), and (iii) the sole form of relief is monetary damages which are paid in full by the Indemnitor. The Indemnitor shall conduct the defense of the Third Party Claim actively and diligently, and the Indemnitee will provide reasonable cooperation in the defense of the Third Party Claim. So long as the Indemnitor is reasonably conducting the Third Party Defense in good faith, the Indemnitee will not consent to the entry of any judgment or enter into any settlement with respect to the Third Party Claim without the prior written consent of the Indemnitor (not to be unreasonably withheld or delayed). Notwithstanding the foregoing, the Indemnitee shall have the right to pay or settle any such Third Party Claim, provided that in such event it shall waive any right to indemnity therefor by the Indemnitor for such claim unless the Indemnitor shall have consented to such payment or settlement (such consent not to be unreasonably withheld or delayed). If the Indemnitor assumes a Third Party Defense and is not reasonably conducting the Third Party Defense in good faith, the Indemnitee shall have the right to consent to the entry of any judgment or enter into any settlement with respect to the Third Party Claim without the prior written consent of the Indemnitor, and the Indemnitor shall reimburse the Indemnitee promptly for all Losses incurred in connection with such judgment or settlement.

(g) In the event that (i) an Indemnitee gives Notice of Claim to the Indemnitor and the Indemnitor fails or elects not to assume a Third Party Defense which the Indemnitor had the right to assume under this Section 10.4 or (ii) the Indemnitor is not entitled to assume the Third Party Defense pursuant to this Section10.4, the Indemnitee shall have the right, with counsel of its choice, to defend, conduct and control the Third Party Defense, at the sole cost and expense of the Indemnitor (unless the Indemnitor is not entitled to assume the Third Party Defense pursuant to Section 10.4(c)(iii), in which case the fees and expenses of the Indemnitee’s legal counsel shall be paid by the Indemnitee). In each case, the Indemnitee shall conduct the Third Party Defense actively and diligently, and the Indemnitor will provide reasonable cooperation in the Third Party Defense. If the Indemnitor fails to or is not entitled to assume the defense of such Third Party Claim pursuant to this Section 10.4, the Indemnitor shall have the right to employ separate counsel in any such Third Party Defense and to participate therein, but the fees and expenses of such counsel shall be at the expense of the Indemnitor, and the Indemnitee shall have ultimate control of the defense (subject to the other provisions of this Section). The Indemnitee shall have the right to consent to the entry of any judgment or enter into any settlement with respect to the Third Party Claim on such terms as it may deem appropriate; provided, however, that the amount of any settlement made or entry of any judgment consented to by the Indemnitee without the consent of the Indemnitor shall not be determinative of the validity of the claim, except with the consent of the Indemnitor (not to be unreasonably withheld or delayed). If the Indemnitor does not elect to assume a Third Party Defense which it has the right to assume hereunder, the Indemnitee shall have no obligation to do so.

(h) Each party to this Agreement shall use its commercially reasonable efforts to keep the other Person fully informed of the status of any Third-Party Claim and any related proceedings at all stages thereof where such person is not represented by its own counsel, and to cooperate and to cause its employees to cooperate with and assist the Indemnitee or the Indemnitor, as the case may be, in connection with any Third Party Defense, including attending conferences, discovery proceedings, hearings, trials and appeals and furnishing records, information and testimony, as may reasonably be requested; provided that each party shall use its best efforts, in respect of any Third Party Claim of which it has assumed the defense, to preserve the confidentiality of all confidential information and the attorney-client and work-product privileges.

10.5 Indemnification Procedures for Non-Third Party Claims. In the event of a claim that does not involve a Third Party Claim being asserted against it, the Indemnitee shall send a Notice of Claim to the Indemnitor. The Notice of Claim shall set forth the amount, if known, or, if not known, an estimate of the foreseeable maximum amount of claimed Losses (which estimate shall not be conclusive of the final amount of such Losses) and a description of the basis for such claim. The Indemnitor will have 30 days from receipt of such Notice of Claim to dispute the claim and will reasonably cooperate and assist the Indemnitee in determining the validity of the claim for indemnity. If the Indemnitor does not give notice to the Indemnitee that it disputes such claim within 30 days after its receipt of the Notice of Claim, the claim specified in such Notice of Claim will be conclusively deemed a Loss subject to indemnification hereunder.

10.6 Payment of Claims. In lieu of paying cash to satisfy its indemnification obligations under this Agreement, Seller, at its option, may satisfy such obligations in whole or in part by surrender of Purchase Price Shares to Buyer or, in case of Claims for Environmental Losses, with Escrow Purchase Price Shares; provided that, if any indemnification obligation for Environmental Losses remains unsatisfied for more than thirty days after the amount of the indemnification obligation is finally determined, then Buyer, at its option, may elect to receive Escrow Purchase Price Shares in lieu of cash to satisfy such obligations in accordance with the terms of the Escrow Agreement. For purposes of any such payment, the value of a Purchase Price Share delivered in satisfaction of an indemnity claim (the “Share Value”) shall be the volume-weighted average sale prices of the Buyer Common Stock on the OTC Bulletin Board or primary stock exchange on which the Common Stock is then listed for the 60 most recent trading days on which sales have occurred ending on the trading day prior to the relevant date of determination; provided that, if the Buyer Common Stock is not then quoted on the OTC Bulletin Board or any stock exchange, then the Share Value shall be determined by independent appraisal by a mutually selected appraiser. If Buyer and Seller are unable to agree on the independent appraiser within five Business Days after a notice by Seller of its intent to deliver shares in lieu of cash, or a notice by Buyer of its intent to receive Escrow Purchase Price Shares in lieu of cash, as the case may be, then either Buyer or Seller may request that the American Arbitration Association appoint an arbitrator according to its rules who shall then select an appraiser. In all cases, the Share Value shall be subject to equitable adjustment in the event of any stock split, stock dividend, reverse stock split or similar event affecting the Buyer Common Stock during the period of calculation and, thereafter, until delivery of the Buyer Common Stock in payment of indemnification obligations pursuant to this Section 10.6.

10.7 No Contribution. Seller acknowledges and agrees that, upon and following the Closing, neither the Acquired Company nor any of its Subsidiaries shall have any liability or obligation to indemnify, save or hold harmless or otherwise pay, reimburse or make Seller whole for or on account of any indemnification or other claims made by any Buyer Indemnitee hereunder. Seller shall have no right of contribution against the Acquired Company or any of its Subsidiaries with respect to any such indemnification or other claim.

10.8 No Consequential Damages. Except with respect to amounts actually paid by Indemnitees with respect to Third Party Claims, Seller shall not be liable for (i) any punitive damages or any consequential damages, or any diminution in value, regardless of the form of action through which such damages are sought, (ii) any lost profits of any Person, even if under applicable Law such lost profits would not be considered consequential or special damages, or (iii) without limiting the generality of the foregoing, any damages calculated by using or taking into account any multiple of earnings, book value or cash flow, in each case except if such damages arise from fraud or from willful misrepresentation or willful breach of warranty. For the purpose of this Section 10.8, the term “consequential damages” shall mean damages that are not the natural, probable and reasonably foreseeable result of the breach.

10.9 Tax Treatment of Indemnification Payments. Except as otherwise required by applicable Law, the parties shall treat any indemnification payment made hereunder as an adjustment to purchase price.

10.10 Mitigation. Each Indemnitee shall use reasonable efforts to mitigate any liabilities and damages for which it may claim indemnification under this ARTICLE X.

10.11 Exclusive Remedy. The indemnities provided for in this ARTICLE X shall be the sole and exclusive remedy of the parties after the Closing with respect to, arising out of, or resulting from this Agreement (including for any inaccuracy of any representation or warranty or any failure or breach of any covenant, obligation, condition or agreement contained in this Agreement); provided, however, that the foregoing shall not (i) limit the rights of any party to seek any equitable remedy available to enforce the rights of such party under this Agreement or (ii) limit the right of a party to seek any available remedy for fraud or willful misrepresentation or willful breach of warranty. Each party covenants and agrees that following the Closing it shall not seek or assert any other remedy hereunder, other than any equitable remedy available to enforce the rights of such party under this Agreement and the right of such party to seek any available remedy for fraud or willful misrepresentation or willful breach of warranty.

EXHIBIT D

A. Buyer and Seller shall enter into a joint venture to develop the exploration play in the Rio d’Oro License Block as shown on the map attached as Annex D-1 (the “Strip”) once written amendments to the terms of the Company’s contract with Ecopetrol satisfactory to Buyer and Seller are granted by Ecopetrol. Buyer will own 70% of the joint venture and commit to pay 70% of the geological and geophysical costs, and Seller will own 30% of the joint venture and commit to pay 30% of the geological and geophysical costs, up to a maximum commitment by Seller of $1,500,000. If the total costs of the venture exceed $5,000,000 (i.e., if Seller’s 30% portion exceeds $1,500,000), then Seller may elect either (a) not to pay any additional costs of the venture, in which case all future payments by Buyer will dilute ownership percent in proportion to the percentage of total venture costs paid by each party, or (b) to continue to pay additional costs of the venture at 30% or (c) to pay a larger proportion of the costs of the venture, in which case Seller’s ownership percent will be increased in proportion to the percentage of total venture costs paid by each party, up to a maximum ownership interest for Seller of 50%.

B. If Buyer and Seller are unable to conclude satisfactory written amendments to the terms of the Company’s contract with Ecopetrol relating to the exploration and development of the Strip, each of Buyer and Seller agrees that for a period of two years after the date of this Agreement it will not, and it will cause its Subsidiaries and its and their respective directors, officers, employees, Affiliates and Representatives not to, pursue the making or implementation of any exploration and development of the Strip without first giving the other party (or, in the case of Seller, Seller’s designee, provided such designee is an Affiliate of Seller) the option (the “JV Option”) to enter into a joint venture with respect to such exploration and development in which Buyer will own 70% of the joint venture and commit to pay 70% of the geological and geophysical costs, and Seller will own 30% of the joint venture and commit to pay 30% of the geological and geophysical costs, up to a maximum commitment by Seller of $1,500,000. If the total costs of the venture exceed $5,000,000 (i.e., if Seller’s 30% portion exceeds $1,500,000), then Seller may elect either (a) not to pay any additional costs of the venture, in which case all future payments by Buyer will dilute ownership percent in proportion to the percentage of total venture costs paid by each party, or (b) to continue to pay additional costs of the venture at 30% or (c) to pay a larger proportion of the costs of the venture, in which case Seller’s ownership percent will be increased in proportion to the percentage of total venture costs paid by each party, up to a maximum ownership interest for Seller of 50%. If either Party does not for any reason accept such JV Option within a reasonable time after the other Party (the “Offeror”) has proposed in writing to make or implement any exploration and development of the Strip, the Offeror shall be free to undertake such proposed exploration and development of the Strip, either by itself or with any other Person or Persons.

C. Except with respect to this Agreement and the transactions contemplated hereby, each of Buyer and Seller agrees that for a period of three years after the date of this Agreement it will not, and it will cause its Subsidiaries and its and their respective directors, officers, employees, Affiliates and Representatives not to, pursue any Exploration Proposal (as defined below) in the Catatumbo Region without first giving the other party (or, in the case of Seller, Seller’s designee, provided such designee is an Affiliate of Seller) the option to have a 50% participation in such Exploration Proposal, or such lower participating interest as may be designated by the other party (or its designee). For purposes of this paragraph, “Exploration Proposal” means (a) the making or implementation of any exploration and development of Hydrocarbons in the Catatumbo area of Colombia, and (b) the making or implementation of any exploration and development of the Strip if such exploration and development is not otherwise addressed in clause “A” or clause “B” above.
