This Agreement has been duly executed and delivered on behalf of Buyer and constitutes (and the Assignment and other agreements and instruments to be delivered by Buyer at Closing, when executed and delivered at Closing, will constitute) the legal, valid and binding obligation of Buyer, enforceable in accordance with its terms, except as limited by bankruptcy or other similar laws applicable generally to creditor’s rights and as limited by general equitable principles.

6.5 Independent Evaluation. Buyer is sophisticated in the evaluation, purchase, ownership and operation of offshore oil and gas properties and related facilities. In making its decision to enter into this Agreement and to consummate the transactions contemplated herein, Buyer (a) has relied or shall rely solely on its own independent investigation and evaluation of the Properties and the advice of its own legal, tax, economic, environmental, engineering, geological and geophysical advisors and the express provisions of this Agreement and not on any comments, statements, projections or other materials made or given by any of Seller’s employees or representatives or consultants or advisors engaged by Seller, and (b) has satisfied or shall satisfy itself through its own due diligence as to the environmental and physical condition of and contractual arrangements and other matters affecting the Properties.

6.8 Buyer’ Ability to Take Title. Buyer is qualified and shall thereafter continue to be qualified to own federal oil, gas and mineral leases in the federal waters in the Gulf of Mexico, and the consummation of the transactions contemplated in this Agreement will not cause Buyer to be disqualified as such an owner. Buyer acknowledges that none of the bonds, letters of credit and guarantees, if any, posted by Seller or its affiliates with the MMS or other governmental entities and relating to the Properties are transferable to Buyer. To the extent required by any applicable laws and except to the extent, if any, that Buyer will, as of Closing, be covered by the bonds of third party operators of the applicable Properties, Buyer will have as of Closing, and will thereafter continue to maintain, lease bonds, area-wide bonds or any other surety bonds as may be required by, and in accordance with, all applicable laws governing the ownership of such leases, and has filed any and all required reports necessary for such ownership with the MMS and all other governmental entities having jurisdiction over such ownership, including but not limited to adequate financial assurance in accordance with the Oil Pollution Act of 1990, as amended.

7.1.1. not (a) act in any manner with respect to the Properties other than in the normal, usual and customary manner, consistent with prior practice; (b) dispose of, encumber or relinquish any of the Properties (other than relinquishment resulting from the expiration of a non-producing Lease still in its primary term or the abandonment of a Lease not operated by a Seller); (c) waive, compromise or settle any right or claim with respect to any of the Properties that could have an Material Adverse Effect; or (d) except with respect to those matters identified in Schedule 7.1.1, make capital or workover expenditures with respect to the Properties in excess of $5,000,000 (net to Seller’s interest), except when required by an emergency when there shall have been insufficient time to obtain advance consent (provided, that Seller will promptly notify Buyer of any such emergency expenditures);

7.1.2. use commercially reasonable efforts to preserve relationships with all third parties having business dealings with respect to the Properties;

7.1.3. until Closing maintain all insurance with respect to the Properties as required by the terms of the Leases or Contracts;

Buyer acknowledges that Seller owns only undivided interests in the Properties and that it is not the operator of any thereof, and Buyer agrees that the acts or omissions of the other working interests owners (including the operators) shall not constitute a breach of the provisions of this Section 7.1, nor shall any action required by or taken pursuant to a vote of working interest owners constitute such a breach so long as Seller has voted its interest in a manner that complies with the provisions of this Section 7.1.

If determined to be necessary by the Parties, Seller shall file or cause to be filed with the Federal Trade Commission and the United States Department of Justice any notifications required to be filed under the H-S-R Act and the rules and regulations promulgated thereunder with respect to the transactions contemplated hereby. In such case, Seller shall consult with Buyer as to the appropriate time of filing such notifications and shall use its best efforts to make such filings at the agreed upon time, to respond promptly to any requests for additional information made by either of such agencies, and to cause the waiting periods under the H-S-R Act to terminate or expire at the earliest possible date after the date of filing.

Seller’s failure to obtain such consents or waivers shall be considered a Title Defect under Article 11. Seller shall provide Buyer with copies of all correspondence sent and received by Seller with respect to the consents, approvals and preferential rights notices sent out in accordance with this Section 7.4.

7.5 Access. From and after the date hereof and up to and including the Closing Date (or earlier termination of this Agreement) but subject to the other provisions of this Section 7.5 and obtaining any required consents of third parties, including third party operators and other owners of the Properties (with respect to which consents Seller shall use commercially reasonable efforts to obtain), Seller shall afford to Buyer and its officers, employees, agents, accountants, attorneys, investment bankers and other authorized representatives (“Buyer’s Representatives”) full access, during normal business hours and upon reasonable notice, to all Records and other documents in Seller’s or any of its affiliates’ possession relating primarily to the Properties. Seller shall also make available to Buyer and Buyer’s Representatives, upon reasonable notice during normal business hours, Seller’s personnel knowledgeable with respect to the Properties in order that Buyer may make such diligence investigation as Buyer considers necessary or appropriate. All investigations and due diligence conducted by Buyer or any Buyer’s Representative shall be conducted at Buyer’s sole cost, risk and expense and any conclusions made from any examination done by Buyer or any Buyer’s Representative shall result from Buyer’s own independent review and judgment.

7.6 Cooperation on Tax Matters. Buyer and Seller shall cooperate fully, as and to the extent reasonably requested by the other Party, in connection with the filing of any Tax Returns and any audit, litigation or other proceeding with respect to Taxes.

ARTICLE 11

TITLE MATTERS

11.1 Title Defect Notice. Buyer shall in good faith provide Seller with written notice (a “Title Defect Notice”) at or before the Defect Notification Deadline of any fact that renders Seller’s title to any Property less than Good and Defensible Title (“Title Defect”); provided, however, Buyer agrees to use its good faith efforts to notify Seller of Title Defects as promptly as possible after Buyer has discovered and made the decision to assert the same. Each Title Defect Notice shall include, in reasonable detail, a description of (i) the Well or Lease with respect to which the claimed Title Defect(s) relate, (ii) the nature of such claimed Title Defect(s) and (iii) Buyer’s calculation of the value of each claimed Title Defect(s) in accordance with the guidelines set forth in Section 11.3. Any Title Defect that is not identified in a timely delivered Title Defect Notice shall thereafter be forever waived and expressly assumed by Buyer. Notwithstanding the foregoing, Buyer will not be required to provide Seller a Title Defect Notice with respect to any consent requirement referenced on Schedule 5.3.

11.2 Determination of Title Defects and Defect Values.

11.2.1. Within ten days after Seller’s receipt of a Title Defect Notice, Seller shall notify Buyer as to whether Seller agrees with the Title Defects claimed therein and/or the values proposed for such Title Defects therein. If Seller does not agree with any such claimed Title Defect and/or any such proposed value, then the Parties shall promptly

enter into good faith negotiations and shall attempt to agree on such matters. The value agreed by the Parties with respect to a Title Defect shall be the Defect Value for such Title Defect.

11.2.2. If the Parties cannot reach agreement concerning either the existence of a Title Defect or a value therefor with respect to any Property prior to Closing, then, upon any Party’s written request, the Parties shall submit such dispute to a mutually acceptable attorney or other consultant experienced in title examination in the state offshore which such Property is located for prompt resolution; provided, however, that if at any time any consultant so chosen fails or refuses to perform hereunder, a new consultant shall be chosen by the Parties. The cost of any such consultant shall be borne 50% by Seller and 50% by Buyer. For any such dispute resolution process, Seller and Buyer shall present a written statement of their respective positions on the dispute to the consultant within three Business Days after the consultant is selected, and the consultant shall make a determination of all points of disagreement in accordance with the terms and conditions of this Agreement within ten Business Days of receipt of such statements. The determination by the consultant shall be conclusive and binding on the Parties and shall be enforceable against any Party in any court of competent jurisdiction, and the value determined by the consultant with respect to a Title Defect shall be the Defect Value for such Title Defect. If necessary to complete such determination, the Closing Date shall be deferred until the consultant has made a determination of the disputed issues with respect thereto and all subsequent dates and required activities having reference to the Closing Date shall be correspondingly deferred; provided, however, that, unless the Parties mutually agree in writing to the contrary, the Closing Date shall not be deferred under this Section 11.2.2 in any event for more than ten Business Days, in which case the affected Property shall be removed from this Agreement until the disputed issues are resolved. In such a case, the Purchase Price shall be reduced by the Allocated Value of such Property. If and when the disputed issues are resolved (unless either Party shall have previously exercised their rights under Section 11.4 to effect a Title Defect Removal with respect to such Property), Seller shall convey the affected Property to Buyer and Buyer shall pay to Seller the Allocated Value minus the Defect Value so resolved for such Property. From the Closing through the date of conveyance, Seller shall continue to conduct its ownership activities with respect to such Property pursuant to the provisions of Article 7 and any other applicable provisions of this Agreement.

11.2.3. Seller shall have the right, but not the obligation, to cure any fact agreed or determined to be a Title Defect.

11.3 Calculation of Defect Value.

11.3.1. If, because of the Title Defect, title to a particular Property or Well fails completely with the effect that Seller has no ownership interest in the relevant Property, the Defect Value shall be the Allocated Value of that Property assigned specifically to it on Exhibit B.

11.3.2. If a Title Defect exists because Seller owns a lesser Net Revenue Interest in a Property and such Property has an Allocated Value assigned specifically to it on

Exhibit B, then the Defect Value shall be equal to (a) the Allocated Value minus (b) the product of (i) the Allocated Value times (ii) (A) the Net Revenue Interest owned divided by (B) the Net Revenue Interest assigned on Exhibit B.

11.3.3. If a Title Defect is a lien, encumbrance or other charge upon a Property which is liquidated in amount and such lien, encumbrance or other charge is not securing borrowed funds of Seller, and such Title Defect is not a Minimal Defect, then prior to Closing Seller shall either (a) instruct Buyer to pay at Closing the sum necessary to be paid to the obligee to remove the Title Defect from such Property (the aggregate of all such amounts, the “Liquidated Title Defect Payment”) or (b) retain the obligation of such Title Defect and elect to challenge the validity thereof (or of any portion thereof), in which case Buyer shall extend reasonable cooperation to Seller in such efforts at no risk or expense to Buyer; provided, however, that if such Title Defect is not cured by three days prior to Closing, it shall constitute an Uncured Title Defect. If a Title Defect is a lien, encumbrance or other charge upon a Property which is securing borrowed funds of Seller, then prior to Closing Seller shall obtain a release of any such lien, encumbrance or other charge.

11.3.4 If a Title Defect represents an obligation or burden upon a Property for which the economic detriment to Buyer is not liquidated but can be estimated with reasonable certainty, the Defect Value with respect to such Title Defect shall be the sum the Parties mutually agree upon in good faith as the present value of the adverse economic effect such Title Defect will have on such Property. If the Parties cannot reach an agreement as to such Defect Value, then such dispute shall be resolved in the manner set forth in Section 11.2.

11.3.5 The Defect Value shall take into consideration all of the applicable guidelines as are set forth in Sections 11.3.1, 11.3.2, 11.3.3, and 11.3.4 above.

11.4 Exclusion of Properties Subject to Title Defects. With respect to any Property subject to an Uncured Title Defect having a Defect Value in excess of $35,000,000, Seller shall have the option (which must be exercised by written notice to Buyer at least two days prior to Closing) to remove such Property from this Agreement, in which case the Purchase Price shall be reduced by the Allocated Value of such Property. From and after the Closing Date, with respect to any Property that is the subject of an Uncured Title Defect or Defect Value dispute and not conveyed at the Closing Date, Seller shall retain the option described above, which may be exercised by written notice to Buyer at any time prior to resolution of such dispute. If a third party exercises an applicable preferential right of purchase with respect to any Property, the Purchase Price shall be reduced by the Allocated Value of such Property. If third parties exercise applicable preferential purchase rights with respect to the Properties comprising the “Bigfoot Prospect”, the Properties comprising the “Bigfoot North Prospect” shall be removed from this Agreement, in which case the Purchase Price shall be reduced by the aggregate Allocated Value of such Properties. The removal of a Property or portion thereof under this Section 11.4 is referred to as a “Title Defect Removal”.

11.5 Purchase Price Adjustment for Title Benefits. If it is agreed or determined at or before two days prior to the Closing Date that Seller owns a greater Net Revenue Interest in a

Property (other than a Property subject to a Title Defect Removal) than is set forth in Exhibit B, such greater value shall be credited against the value of any Title Defect Removal effected pursuant to the first or second sentences of Section 11.4.

If a Loss is asserted against a Party for which the other Party may have an obligation of indemnity and defense (whether under this Article 14 or any other provision of this Agreement), the Party seeking indemnification (“Indemnified Party”) shall give the Party from which the Indemnified Party seeks indemnification (“Indemnifying Party”) prompt written notice of the Loss, setting forth the particulars associated with the Loss (including a copy of the written Loss, if any) as then known by the Indemnified Party (“Loss Notice”).

14.7 Defense of Losses. Within thirty (30) days after the Indemnifying Party receives a Loss Notice, the Indemnifying Party shall notify the Indemnified Party whether or not the Indemnifying Party will assume responsibility for defense and payment of the Loss. The Indemnified Party is authorized, prior to and during such thirty (30) day period, to file any motion, pleading or other answer that it deems necessary or appropriate to protect its interests, or those of the Indemnifying Party, and that is not prejudicial to the Indemnifying Party. If the Indemnifying Party elects not to assume responsibility for defense and payment of the Loss, the Indemnified Party may defend against, or enter into any settlement with respect to, the Loss as it deems appropriate without relieving the Indemnifying Party of any indemnification obligations the Indemnifying Party may have with respect to such Loss. The Indemnifying Party’s failure to respond in writing to a Loss Notice within the thirty (30) day period shall be deemed an election by the Indemnifying Party not to assume responsibility for defense and payment of the Loss. If the Indemnifying Party elects to assume responsibility for defense and payment of the Loss: (a) the Indemnifying Party shall defend the Indemnified Party against the Loss with counsel of the Indemnifying Party’s choice (reasonably acceptable to the Indemnified Party, which shall cooperate with the Indemnifying Party in all reasonable respects in such defense), (b) the Indemnifying Party shall pay any judgment entered or settlement with respect to such Loss, (c) the Indemnifying Party shall not consent to entry of any judgment or enter into any settlement with respect to the Loss that (i) does not include a provision whereby the plaintiff or claimant in the matter releases the Indemnified Party from all liability with respect to the Loss or (ii) contains terms that may materially and adversely affect the Indemnified Party (other than as a result of money damages covered by the indemnity), and (d) the Indemnified Party shall not consent to entry of any judgment or enter into any settlement with respect to the Loss without the Indemnifying Party’s prior written consent, which consent shall not be unreasonably withheld or delayed. In all instances the Indemnified Party may employ separate counsel and participate in defense of a Loss, but the Indemnified Party shall bear all fees and expenses of counsel employed by the Indemnified Party.

ARTICLE 15

RISK OF LOSS

15.1 Casualty Loss. If, after the date hereof and prior to the Closing any portion of the Properties shall be substantially damaged or destroyed by fire or other casualty, or if any substantial portion of the Properties shall be taken by condemnation or the exercise of eminent domain (in either case, a “Casualty Loss”), Buyer shall be entitled to any applicable insurance proceeds or condemnation awards and an adjustment to the Purchase Price based upon the Allocated Value of the Property destroyed or harmed, to the extent such loss is not covered by insurance or condemnation award; provided, however, that if prior to Closing a Casualty Loss (after taking into account insurance and indemnity proceeds) occurs of more than ten percent (10%) of the Purchase Price, Seller or Buyer shall have the right to terminate this Agreement by delivery of written notice to the other Parties.

15.2 Buyer’ Risk of Loss. Except as specifically provided in Section 15.1 with respect to any Casualty Loss, Buyer shall assume all risk of loss with respect to any change in condition of the Properties from the Effective Time and Seller shall have no liability for losses or damages sustained with respect to the condition of the Properties or their ability to produce Hydrocarbons (other than with respect to any violation by Seller of the pre-closing covenants contained in Section 7.1).

ARTICLE 16

16.1.1. The Parties may terminate this Agreement by mutual written consent at any time prior to the Closing Date.

16.1.2.

16.2 Effect of Termination. Each Party’s right of termination under Section 16.1 is, subject to Section 19.15, in addition to any other rights it may have under this Agreement or otherwise, and the exercise of such right of termination will not be an election of remedies. If this Agreement is terminated pursuant to Section 16.1, all obligations of the Parties under this Agreement will terminate, except that the obligations of the Parties in this Section 16.2 and Article 19, will survive; provided, however, that if this Agreement is terminated because of a willful or intentional breach of this Agreement by the non-terminating Party or because a Party’s condition to Closing is not satisfied as a result of the non-terminating Party’s willful or intentional failure to comply with its obligations under this Agreement, subject to Section 19.15, the terminating Party will be entitled to pursue all remedies available at law for damages or other relief, in equity or otherwise.

16.3 Specific Performance and Other Remedies. Each Party hereby acknowledges that the rights of each Party to consummate the transactions contemplated hereby are special, unique and of extraordinary character and that, in the event that either Party violates or fails or refuses to perform any covenant or agreement made by it herein, the non-breaching Party may be without an adequate remedy at law. In the event that either Party violates or fails or refuses to perform any covenant or agreement made by such Party herein, the non-breaching Party may, subject to the terms hereof and in addition to any remedy at law for damages or other relief, institute and prosecute an action in any court of competent jurisdiction to enforce specific performance of such covenant or agreement or seek any other equitable relief.

ARTICLE 17

19.4 Entire Agreement.

19.5 Amendment; Waiver. No amendment, modification, replacement, termination or cancellation of any provision of this Agreement will be valid, unless the same shall be in writing and signed by Buyer and Seller. No waiver by any Party of any default, misrepresentation or breach of warranty or covenant hereunder, whether intentional or not, may be deemed to extend to any prior or subsequent default, misrepresentation, or breach of warranty or covenant hereunder or affect in any way any rights arising because of any prior or subsequent such occurrence.

19.6 Severability. The provisions of this Agreement will be deemed severable and the invalidity or unenforceability of any provision will not affect the validity or enforceability of the other provisions hereof; provided, however, that if any provision of this Agreement, as applied to any Party or to any circumstance, is adjudged by a court of competent jurisdiction, arbitrator, or mediator not to be enforceable in accordance with its terms, the Parties agree that the court of competent jurisdiction, arbitrator, or mediator making such determination will have the power to modify the provision in a manner consistent with its objectives such that it is enforceable, and/or to delete specific words or phrases, and in its reduced form, such provision will then be enforceable and will be enforced.

19.7 Construction. The Parties have participated jointly in the negotiation and drafting of this Agreement. If an ambiguity or question of intent or interpretation arises, this Agreement will be construed as if drafted jointly by the Parties and no presumption or burden of proof will arise favoring or disfavoring any Party because of the authorship of any provision of this Agreement. Any reference to any federal, state, local, or foreign law will be deemed also to refer to such law as amended and all rules and regulations promulgated thereunder, unless the context requires otherwise. The words “include,” “includes” and “including” will be deemed to be followed by “without limitation.” Pronouns in masculine, feminine, and neuter genders will be construed to include any other gender, and words in the singular form will be construed to include the plural and vice versa, unless the context otherwise requires. The words “this Agreement,” “herein,” “hereof,” “hereby,” “hereunder” and words of similar import refer to this

Agreement as a whole and not to any particular subdivision unless expressly so limited. The Exhibits and Schedules identified in this Agreement are incorporated herein by reference and made a part hereof. References herein to any Section or Article shall be references to a Section or Article of this Agreement unless the context clearly requires otherwise.

After Closing, Seller will maintain as confidential all information permitted to be retained (either as an original or copy) hereunder.

19.9 Headings. The article and Section headings contained in this Agreement are inserted for convenience only and will not affect in any way the meaning or interpretation of this Agreement.

19.10 Counterparts. This Agreement may be executed in two or more counterparts, each of which will be deemed an original but all of which together will constitute one and the same instrument. Delivery of an executed counterpart of this Agreement by telecopier shall be equally as effective as delivery of an original executed counterpart of this Agreement. Any Party delivering an executed counterpart of this Agreement by telecopier also shall deliver an original executed counterpart of this Agreement, but the failure to deliver an original executed counterpart shall not affect the validity, enforceability and binding effect of this Agreement.

19.11 Expenses, Fees and Taxes.

19.11.1. Each of the Parties hereto shall pay its own fees and expenses incident to the negotiation and preparation of this Agreement and consummation of the transactions contemplated hereby, including brokers’ fees. Buyer shall be responsible for the cost of all fees for the recording of transfer documents. All other costs shall be borne by the Party incurring them. All Taxes, whether in the form of income, franchise, or capital gains Taxes, imposed by federal, state, or foreign Tax authorities are the obligation of and shall be borne by the Party incurring such Tax. Notwithstanding anything to the contrary herein, it is acknowledged and agreed by and between Seller and Buyer that the Purchase Price excludes any sales Taxes or other Taxes of a similar nature in connection with the sale of property pursuant to this Agreement. Buyer and Seller will use commercially reasonable efforts and cooperate in good faith to exempt the sale, conveyance, assignments and transfers to be made to Buyer from any sales, use, stamp, real estate transfer, documentary, registration, recording and other similar Taxes (collectively “Transfer Taxes”). If a determination is ever made that a Transfer Tax applies, Buyer shall be liable for such Tax. Buyer shall indemnify and hold Seller Group harmless with respect to the payment of any of such Taxes, including any interest or penalties assessed thereon. The indemnity and hold harmless obligation contained in the preceding sentence shall survive the Closing.

19.11.2. If the transactions hereunder constitute an applicable asset acquisition pursuant to Section 1060 of the Code, the Parties agree to cooperate in the preparation of Form 8594. The Parties agree that the Allocated Value for each property on Exhibit B shall be used for this purpose. Buyer and Seller shall (a) be bound by this allocation for all Tax purposes, (b) timely file all forms (including IRS Form 8594) and Tax returns required to be filed in connection with this allocation, (c) prepare and file all Tax returns in a manner consistent with this allocation, and (d) take no position inconsistent with this allocation in any Tax return, any audit or examination by, or any proceeding before, any Taxing authority or otherwise. In the event that the allocation is disputed by any Taxing authority, the Party receiving notice of such dispute shall promptly notify and consult with the other Party and keep the other Party apprised of material developments concerning resolution of such dispute.

19.11.3. To the extent applicable, Seller shall cooperate with Buyer and any Tax partnership of which Seller is a partner in making an election under Section 754 of the Code and, if requested by Buyer and required by the Code, Seller shall also sign such election with respect to an applicable Tax partnership’s tax year which includes the Closing Date to adjust the basis of such Tax partnership’s assets under Section 743 of the Code.

From and after the Closing, (a) Buyer shall comply with all applicable laws, ordinances, rules and regulations and shall properly obtain and maintain all material permits required by the MMS and other governmental entities with regard to the Properties, and shall provide and maintain with the applicable regulatory agency(ies) all required bonds, and (b) Buyer shall assume all of the P&A Obligations including, where applicable, the plugging of Xxxxx and the restoration of the surface in compliance with all applicable laws, rules, regulations and in compliance with all Leases and other agreements affecting the Properties, and shall indemnify and hold Seller Group harmless with respect to any and all of those obligations. Such obligations shall survive the Closing and Buyer shall remain liable therefor as concerns Seller even if Buyer shall assign, sell or transfer the Properties to a third party.

19.13 Tax-Deferred Exchange Option. Either Party shall have the right to elect to effect a Tax-deferred exchange under Code Section 1031 (a “Tax-Deferred Exchange”) for all or part of the Properties at any time prior to the Closing Date. If a Party elects to effect a Tax-Deferred Exchange (“Electing Party”), the other Party agrees to execute escrow instructions, documents, agreements or instruments to effect the exchange; provided, however, that the other Party shall incur no additional costs, expenses, fees or liabilities as a result of or connected with the exchange. Seller and Buyer may assign any of its rights and delegate performance of any of its duties under this Agreement in whole or in part to a third party in order to effect such an exchange; provided, however, that each Electing Party shall remain responsible to the other Party for the full and prompt performance of their respective delegated duties. The Electing Party shall indemnify and hold other Party harmless from and against all claims, expenses (including reasonable attorneys’ fees), loss and liability resulting from its participation in any exchange undertaken pursuant to this Section 19.13 pursuant to the request of Electing Party.

19.14 Public Announcements. The Parties agree that prior to making any public announcement or statement with respect to the transactions contemplated by this Agreement, the

Party desiring to make such public announcement or statement shall consult with the other Party hereto and endeavor in good faith to obtain approval of the other Party to the text of a public announcement or statement to be made solely by Seller, on the one hand, or Buyer, on the other, as the case may be; provided, however, if Seller, on the one hand, or Buyer, on the other is required by law or the rules of the New York Stock Exchange or Oslo Stock Exchange to make such public announcement or statement, then the same may be made without the approval of the other Party, but the Party making such announcement or statement shall promptly provide the other Party with prior notice of such announcement or statement unless such prior notice is prohibited by applicable laws.

19.15 Limitation on Damages. Notwithstanding any term or provision of this Agreement to the contrary, in no event shall any party to this Agreement be liable for any consequential, special, exemplary, punitive or similar damages or lost profits arising out of or relating to this Agreement.
