Profound shall provide PET with, or cause to be provided to PET, within two Business Days following the execution and delivery of this Agreement, a list (in both written and electronic form) of the registered Shareholders, together with their addresses (where available) and respective holdings of Common Shares. Profound shall concurrently provide PET with the names, addresses and holdings of all Persons having securities

issued by Profound to acquire Common Shares (including holders of the Options and Performance Warrants). Profound shall from time to time furnish, or request that its registrar and transfer agent furnish, PET with such additional information, including updated or additional lists of Shareholders, holders of Options, holders of Performance Warrants, mailing labels and lists of securities positions and other assistance, as PET may reasonably request in order to be able to communicate the Offer to the Shareholders and to such other Persons as are entitled to receive the Offer under applicable Laws. All such deliveries shall be in printed form and, if available, in computer-readable form.

Profound covenants and agrees to use reasonable commercial efforts to assist PET and its representatives in having additional Shareholders execute and deliver Lock-up Agreements.

Profound agrees and represents to PET that the Board of Directors has, with no more than one director abstaining or dissenting:

directed Profound to use its commercially reasonable best efforts to ensure that all Persons holding Options and/or Performance Warrants either:

exercise their Options and/or Performance Warrants and tender all Common Shares issued in connection therewith to the Offer; or

cancel, terminate or surrender the rights to exercise or convert, as the case may be, any of their Options and/or Performance Warrants,

cause the vesting of entitlements under the Profound Stock Option Plan and the Performance Warrants to accelerate, such that all outstanding Options and Performance Warrants shall be exercisable and fully vested concurrent with the Expiry Time; and

satisfy all other obligations of Profound under the Profound Stock Option Plan and the Performance Warrants or, upon the acquisition by PET of the Common Shares pursuant to the Offer, to cause all entitlements under such plan and under the terms of the Performance Warrants to terminate or be surrendered,

and Profound agrees to apply for all consents and authorizations required in connection with the foregoing, including any exemptions or consents required from any Canadian Securities Regulatory Authorities and the Toronto Stock Exchange, in connection with any amendments to the Profound Stock Option Plan required in connection with the foregoing and that all proceeds from the exercise of Options and Performance Warrants, if any, shall be retained by Profound.

It is agreed by PET that all Options and Performance Warrants that are tendered to Profound for exercise on or before the Effective Time, conditional on PET taking up Common Shares under the Offer (a "Conditional Exercise"), shall be deemed by PET to have been exercised immediately prior to the Effective Time and PET shall accept as

validly tendered under the Offer as of the Effective Time, all Common Shares that are to be issued pursuant to the Conditional Exercise; provided that, the holders of such Options and Performance Warrants indicate that such Options and Performance Warrants are tendered pursuant to the Offer and provided that such holders agree to surrender any of their remaining unexercised Options and Performance Warrants for cancellation for no consideration immediately prior to the Effective Time. PET agrees to cooperate with Profound in implementing one or more mechanisms (including loans made by Profound or PET to the holders thereof) to facilitate exercise of Options and Performance Warrants to be exercised pursuant to the Conditional Exercise. PET further agrees that Profound may make a payment to each holder of Performance Warrants of $0.01 for each Performance Warrant such holders agree to terminate.

Profound represents to PET that its Board of Directors has determined that the Offer is a Permitted Bid (as defined in the Rights Plan) under the Rights Plan and that the successful completion of the Offer (including any purchases of Common Shares permitted by section 2.2(3) of MI 62-104 during the term of the Offer) will not constitute a Flip-in Event (as defined in the Rights Plan) under the Rights Plan.

Profound covenants and agrees with PET and represents to PET that its Board of Directors has resolved not to waive the application of the Rights Plan or to redeem any of the outstanding Rights or take any other action which would limit the application of the Rights Plan to any transaction.

Each of PET and Profound shall advise, consult and co-operate with each other prior to issuing, or permitting any of its subsidiaries, directors, officers, employees, agents or advisors to issue, any press release or other statement to the press with respect to this Agreement or the Offer. PET and Profound shall not issue any such press release or make any such public statement prior to such consultation, except as may be required by applicable Law or by obligations pursuant to any listing agreement with a stock exchange and only after using its reasonable best efforts to consult the other Party taking into account the time constraints to which it is subject as a result of such Law or obligation.

PET and Profound agree that a news release substantially in the form set out in Schedule "C" shall be issued immediately following the execution of this Agreement.

If, within 120 days after the date of the Offer, the Offer has been accepted by holders of not less than 90% of the Common Shares (excluding Common Shares held by or on behalf of PET, or an "affiliate" or "associate" (as those terms are defined in the ABCA) as at the date of the Offer), PET may acquire the remainder of the Common Shares from those Shareholders who have not accepted the Offer pursuant to Section 195 of the ABCA (a "Compulsory Acquisition"). If that statutory right of acquisition is not available or PET chooses not to avail itself of such statutory right of acquisition, PET shall use its

commercially reasonable efforts to pursue other means of acquiring the remaining Common Shares not tendered to the Offer. Profound agrees with PET that, in the event PET takes up and pays for Common Shares under the Offer representing, together with the number of Common Shares purchased by PET or its Affiliates during the term of the Offer as permitted by section 2.2(3) of MI 62-104, if any, at least 50.1% of the Common Shares (calculated on a fully diluted basis at the Expiry Time excluding any Common Shares issued or issuable on the conversion of the Special Warrants), it will assist PET in connection with any proposed amalgamation, statutory arrangement, capital reorganization or other transaction of Profound and PET or an Affiliate of PET (a "Subsequent Acquisition Transaction") to acquire the remaining Common Shares, provided that the consideration offered in connection with the Subsequent Acquisition Transaction is at least equivalent in value to the consideration offered under the Offer.

Profound agrees that, if PET takes steps to effect a Subsequent Acquisition Transaction that requires approval of Shareholders in a meeting of the Shareholders, Profound will use reasonable commercial efforts to take all action necessary, in accordance with securities Laws, other applicable Laws or any Governmental Authority having jurisdiction, to duly call, give notice of, convene and hold a meeting of Shareholders as promptly as practicable to consider and vote upon the action proposed by PET. In the event of such a meeting or meetings, Profound shall use all commercially reasonable efforts to mail to the Shareholders an Information Circular with respect to any such meeting of the Shareholders. The term "Information Circular" shall mean such proxy or other required informational statement or circular, as the case may be, and all related materials prepared in accordance with Laws at the time required to be mailed to the Shareholders and all amendments or supplements thereto, if any. PET and Profound each shall use all commercially reasonable efforts to obtain and furnish the information required to be included in any Information Circular. The information provided and to be provided by PET and Profound for use in the Information Circular on both the date the Information Circular is first mailed to the Shareholders and on the date that any such meeting is held 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 light of the circumstances under which they are made, not misleading and will comply in all material respects with all applicable requirements of Law. PET and Profound each agree to correct promptly any such information provided by it for use in any Information Circular that shall have become false or misleading.

If PET takes up and pays for the number of Common Shares specified in the Minimum Tender Condition, the Board of Directors of Profound immediately following such acquisition by PET, shall be reconstituted through resignations of all existing Profound directors, excluding any such existing directors which PET desires remain Profound directors and who agree to remain and serve in such capacity and excluding any director indicated in the Disclosure Letter, and the appointment of PET's nominees in their stead. Profound shall, in accordance with the foregoing and subject to the provisions of the ABCA, assist PET to secure the resignations of all such Profound directors to be effective at such time as may be required by PET and to use its commercially reasonable best efforts to cause the election of PET's nominees to fill the vacancies so created in order to effect the foregoing without the necessity of a shareholder meeting. Profound represents that the Board of Directors has determined, with no more than one director abstaining or dissenting from such determination, to use its commercially reasonable best efforts to enable PET to elect or appoint all of the directors of Profound immediately after PET takes up and pays for the number Common Shares specified in the Minimum Tender Condition.

PET and the Administrator hereby jointly and severally represent and warrant to Profound the matters set out on Schedule "D" and acknowledge that Profound is relying upon these representations and warranties in connection with the entering into of this Agreement.

Profound represents and warrants to PET the matters set out on Schedule "E" and acknowledges that PET is relying upon these representations and warranties in connection with the entering into of this Agreement and the making of the Offer.

Profound shall use its reasonable commercial efforts to cause their current insurance (or re-insurance) policies (including insurance policies, and cover provided under policies, held for the benefit of Profound) not to be cancelled or terminated or any of the coverage thereunder to lapse unless, simultaneously with such termination, cancellation or lapse, replacement policies providing coverage equal to or greater than the coverage under the cancelled, terminated or lapsed policies for substantially similar premiums are in full force and effect;

obtain all necessary consents, approvals and authorizations as are required to be obtained by it under any applicable Law;

oppose, lift or rescind any injunction or restraining order or other order or action seeking to stop, or otherwise adversely affecting PET's ability to consummate the transactions contemplated hereby or the Offer; and

shall not take any action that would render, or may reasonably be expected to render, any representation or warranty made by it in this Agreement (i) that is qualified by a reference to a Material Adverse Effect misleading or untrue in any respect, or (ii) that is not qualified by a reference to a Material Adverse Effect untrue or incorrect in any respect unless the failure to be true or correct has not had or would not reasonably be expected to have, a Material Adverse Effect on Profound at any time prior to completion of the Offer or termination of this Agreement, whichever first occurs;

shall promptly notify PET in writing of any Material Adverse Change affecting Profound and of any change in any representation or warranty provided by Profound in this Agreement which change is or may be of such a nature to render any representation or warranty misleading or untrue in any material respect and Profound shall in good faith discuss with PET any change in circumstances (actual, anticipated, contemplated, or to the knowledge of Profound, threatened) which is of such a nature that there may be a reasonable question as to whether notice need to be given to PET pursuant to this provision; and

will furnish promptly to PET or PET's counsel, a copy of each notice, report, schedule or other document delivered, filed or received by surmount in connection with: (i) the Offer; (ii) any filings under applicable Laws in connection with the transactions contemplated hereby; (iii) any dealings with Governmental Entities in connection with the transactions contemplated hereby; and (iv) any reports issued by the depositary under the Offer.

Not more than seven hours before the Expiry Time, Profound shall provide to PET a true and correct certificate of Profound, signed by two senior officers of Profound, not in their personal capacities, confirming, after due and careful inquiry, that:

the representations and warranties of Profound in this Agreement are true and correct in all respects if qualified by a reference to Material Adverse Effect and if not qualified by a reference to Material Adverse Effect (other than with respect to outstanding share capital (both on an undiluted and fully-diluted basis), which shall be true and correct in all respects except for changes thereto resulting from the issuance of Common Shares under the terms of the Options or Performance Warrants), are true and correct in all respects as at the Expiry Time with the same force and effect as if made at such time and regardless of any reference to another time in the representations and warranties unless the failure to be true and correct has not had or would not reasonably be expected to have a Material Adverse Effect on Profound (and, for this purpose, any reference to "material" or other concepts of materiality in such representations and warranties shall be ignored) as at the Expiry Time; and

all of the covenants and obligations of Profound under the Agreement have been performed or complied with in all material respects.

Profound shall immediately cease and cause to be terminated all existing discussions, solicitations, initiations, encouragements and negotiations, if any, with any parties (other than PET or its Affiliates) conducted on or before the date of this Agreement by Profound or any of its officers, directors, employees, financial advisors, legal counsel, representatives or agents ("Profound Representatives") with respect to any actual or potential Acquisition Proposal. Profound shall immediately following the entering into of this Agreement send a letter to all parties who have had discussions or negotiations and who have entered into confidentiality agreements with Profound pertaining to any actual or potential Acquisition Proposal and shall use its reasonable commercial efforts to have all materials provided to such parties by Profound, or prepared by such parties in respect of Profound, destroyed or returned to Profound or Profound Representatives as the case may be in accordance with the terms of the confidentiality agreements with such parties and immediately terminate access to any physical or electronic data room(s) maintained by Profound. Profound shall promptly advise PET orally and in writing of any response or action (actual or threatened) by any recipient of such letter which could hinder, prevent or delay or otherwise adversely affect the completion of the Offer.

After the date hereof, Profound will not authorize or permit any Profound Representatives to, directly or indirectly:

solicit, initiate or encourage, or engage in or continue any discussions or negotiations or participate in or take any other action in respect of, or which may reasonably be expected to lead to, an Acquisition Proposal;

provide or furnish to any party any information concerning Profound and its business, properties and assets in respect of, or which may reasonably be expected to lead to, an Acquisition Proposal;

accept, recommend, approve or enter into any agreement to implement an Acquisition Proposal; or

release any party from any confidentiality or standstill agreement between Profound and such party, prior to the expiry of such agreement in accordance with its terms, or amend any such agreement;

provided however, that notwithstanding any other provisions hereof, Profound and the Profound Representatives may:

engage in discussions or negotiations with any party who (without any solicitation, initiation or encouragement, directly or indirectly, by Profound or Profound Representatives after the date hereof) seeks to initiate such discussions or negotiations, provide or furnish such party with information concerning Profound and its business, properties and assets and participate in or take any other action if such party has first made a bona fide written Acquisition Proposal and the Board of Directors determines such Acquisition Proposal is a Superior Proposal and further determines in good faith, after considering applicable Law and receiving the advice of outside legal counsel (which advice may be reflected in Board of Directors minutes) that such action is necessary in order for the Board of Directors to discharge with its fiduciary duties under applicable Law;

comply with Multilateral Instrument 62-104 and similar provisions and applicable rules under securities Laws relating to the provision of directors' circulars and make appropriate disclosure with respect to any such Acquisition Proposal to holders of Common Shares; and

accept, recommend, approve or enter into any agreement to implement a Superior Proposal and release the party making the Superior Proposal from any standstill provisions but only if prior to such acceptance, recommendation, approval or entering into of an agreement or release, the Board of Directors shall have concluded in good faith, after considering the provisions of applicable Law and after giving effect to all proposals to adjust the terms and conditions of this Agreement and the Offer which may be offered by PET during the two Business Day period set forth in Section 8.2(c) hereof and after receiving the advice of outside counsel (which advice may be reflected in Board of Directors minutes) that such action is necessary in order for the Board of Directors to discharge its fiduciary duties under applicable Law.

Neither Profound nor Profound Representatives shall provide or furnish any information to any party in accordance with Section 8.2(b) unless Profound shall have entered into a confidentiality and standstill agreement following which Profound shall immediately provide PET with any information provided to any such other party which had not previously been provided to PET. Upon receipt of an Acquisition Proposal, Profound agrees to provide immediate notice thereof to PET and shall provide PET with a written description of any such Acquisition Proposal and any amendments thereto and a copy thereof. Profound agrees to notify PET immediately if the Board of Directors determines that any bona fide written Acquisition Proposal constitutes a Superior Proposal. For a period of two Business Days from the time that Profound notifies PET of the fact that the Board of Directors has determined a bona fide written Acquisition Proposal constitutes a Superior Proposal, the Board of Directors agrees not to accept, recommend, approve or enter into any agreement to implement such Superior Proposal and not to release the party making the Superior Proposal from any standstill provisions and shall not withdraw, redefine, modify or change its recommendation in respect of the Offer. In addition, during such two Business Days period, Profound shall, and shall cause its respective financial and legal advisors to, negotiate in good faith with PET to make such adjustments in the terms and conditions of this Agreement and the Offer as would enable PET to proceed with the Offer as amended rather than the Superior Proposal. In the event PET offers to amend this Agreement and the Offer to provide that the holders of Common Shares shall receive a value per Common Share equal to or having a value greater than the value per Common Share provided in the Superior Proposal (the "Amended Offer") and so advises the Board of Directors prior to the expiry of such two Business Days period, the Board of Directors, upon determining that the Amended Offer is superior to the Superior Proposal, shall not accept, recommend, approve or enter into any agreement to implement such Superior Proposal and shall not release the party making the Superior Proposal from any standstill provisions and shall not withdraw, redefine, modify or change its recommendation in respect of the Offer.

Profound and PET agree that all information that may be provided to it by Profound with respect to any Superior Proposal pursuant to this Section 8.2 shall be treated as if it were confidential information under the Confidentiality Agreement and shall not be disclosed or used except: (i) in accordance with the provisions of this Agreement and the Confidentiality Agreement; or (ii) in order to enforce its rights under this Agreement in legal proceedings.

Each Party shall ensure that its officers, directors, employees, financial advisors, legal counsel, representatives and agents are aware of the provisions of this Section 8.2 applicable to such Party. Each Party shall be responsible for any breach of this Section 8.2 by such Party's officers, directors, employees, financial advisors, legal counsel, representatives and agents .

Nothing in this Agreement shall prevent the Board of Directors from making any disclosure to the securityholders of Profound if the Board of Directors, acting in good faith and upon the advice of its legal advisors, shall have first determined that the failure to make such disclosure would be inconsistent with the fiduciary duties of the Board of Directors or applicable Law and provided further that such disclosure is otherwise in accordance with the terms of this Agreement.

PET and its counsel shall be given a reasonable opportunity to review and comment on the form and content of any disclosure made pursuant to Section 8.2(b)(ii) or 8.2(f), recognizing that whether or not such comments are appropriate will be determined by Profound, acting reasonably.

If at any time after the execution of this Agreement and prior to its termination:

the Board of Directors withdraws, modifies or changes, or publicly announces, withdraws, modifies or changes, its recommendations or determinations set forth in Section 2.2(a) in a manner adverse to PET or resolves to do so or recommends or publicly announces a recommendation that Shareholders accept or vote in favour of another transaction or Acquisition Proposal;

the Board of Directors recommends or approves or publicly announces a recommendation or approval of an Acquisition Proposal;

the Board of Directors shall have failed to reaffirm its recommendation of the Offer by news release within three Business Days after the public announcement of any Acquisition Proposal (or, in the event that the Offer shall be scheduled to expire within such three Business Day period, prior to the scheduled expiry of the Offer);

another Acquisition Proposal has been publicly announced and not withdrawn prior to the Expiry Time, the Minimum Tender Condition has not been satisfied at the Expiry Time, and such Acquisition Proposal is subsequently completed within twelve months of the Expiry Time;

Profound enters into any agreement with any Person with respect to an Acquisition Proposal prior to the Expiry Time; or

the Agreement is terminated by PET pursuant to Section 11.1(b)(ii) or (iii), or by Profound pursuant to Section 11.1(j),

then in any such case Profound shall pay to PET, or as PET otherwise directs, forthwith and in any event within two Business Days after such event, by way of wire transfer of immediately available funds to an account designated by PET (or such other form of consideration as the Parties may agree), the sum of $1,250,000 (the "Non-Completion

Fee"). As of the moment the earliest of any of the events specified in Sections 8.3(a)(i), (ii), (iii), (iv), (v) or (vi) occurs, Profound shall hold such amount in trust for PET.

If Profound does not have sufficient financial resources to pay the Non-Completion Fee, then it shall be a condition of (i) any Superior Proposal and (ii) any Acquisition Proposal where Profound or any affiliate has entered into any agreement to support such Acquisition Proposal that the person making such Acquisition Proposal shall advance or otherwise provide to Profound the cash required for Profound to pay the Non-Completion Fee, which amount shall be so advanced or provided prior to the date on which Profound is required to pay the Non-Completion Fee.

For greater certainty, the Parties agree that any Non-Competition Fee paid pursuant to Section 8.3 as a result of the occurrence of any of the events referenced in Section 8.3 is a payment of liquidated damages which are a genuine pre-estimate of the damages, including opportunity costs, that PET will suffer or incur as a result of the event giving rise to such damages and the resultant termination of this Agreement and are not penalties and, subject to the proviso below, shall be the sole remedy of PET in damages with respect to any such event or termination. Each Party irrevocably waives any right it may have to raise as a defence that any such liquidated damages are excessive or punitive. Any payment made pursuant to Section 8.3 hereof shall be without prejudice to the rights and remedies available to PET in respect of any Claim based on any intentional, fraudulent or bad faith breach, failure to comply with or default of this Agreement by Profound or Profound Representatives.

Subject to the Confidentiality Agreements and Laws, upon reasonable notice, Profound shall afford PET's officers, employees, counsel, accountants and other authorized representatives and advisors (the "PET Representatives") reasonable access during normal business hours from the date hereof and until the earlier of the Expiry Time or the termination of this Agreement, to its properties, books, Contracts and records as well as to its management personnel to, among other things, enable PET to efficiently integrate the business and affairs of Profound with PET and during such period, Profound shall upon reasonable notice provide PET with all information concerning Profound's businesses, properties and personnel as PET or PET Representatives may reasonably request. Nothing in the foregoing shall require Profound to disclose information subject to a confidentiality agreement with a third party in effect prior to the date hereof where such disclosure would be in violation of the terms of that agreement.

Profound agrees that, upon request by PET, Profound shall in good faith consider:

effecting such reorganizations of its business, operations and assets or such other transactions as PET may request, acting reasonably (each, a "Pre-Acquisition Reorganization"); and

cooperating with PET and its advisors in order to determine the nature of the Pre-Acquisition Reorganizations that might be undertaken and the manner in which they might most effectively be undertaken,

provided that, in the opinion of Profound or its counsel, acting reasonably, the Pre-Acquisition Reorganizations are not prejudicial to Profound, nor will they be prejudicial to Profound in the event the Offer is not completed. PET shall provide written notice to Profound of any proposed Pre-Acquisition Reorganization at least seven Business Days prior to the Expiry Time. Upon receipt of such notice and

agreement of Profound to the proposal set forth therein, PET and Profound shall work co-operatively and use reasonable commercial efforts to prepare prior to the Expiry Time all documentation necessary and do all such other acts and things as are reasonably necessary to give effect to such Pre-Acquisition Reorganization. In the event that the Take-Up Date does not occur, all reasonable costs associated with such Pre-Acquisition Reorganization shall be borne by PET.

Profound shall not settle or compromise any Claim brought by any present, former or purported holder of any securities of Profound in connection with the transactions contemplated by this Agreement prior to the Effective Time without the prior written consent of PET, which shall not be unreasonably withheld or delayed.

Profound shall in good faith consider establishing a hedging program with the assistance of PET, including but not limited to consideration of one or more Swaps, for Profound's future production and sales of oil, natural gas and natural gas liquids, in form and substance satisfactory to PET, acting reasonably, provided that: (a) PET shall indemnify Profound for any liability or hedging losses arising directly from such hedging program during the term of this Agreement in the event that this Agreement is validly terminated by Profound pursuant to Section 11.1(c); and (b) in the event that the Non-Completion Fee becomes payable, PET shall have no obligation to indemnify Profound for any liability or loss arising from such hedging program or any Swaps and Profound shall be liable to remit to PET, immediately upon termination of this Agreement (and without detracting from any obligation of Profound to pay to PET the Non-Completion Fee), the profits (if any) realized by Profound from such hedging program (including Swaps) during the term of this Agreement.

For the purposes of this Section 8.9, "Transferred Information" means the personal information (namely, information about an identifiable individual other than their business contact information when used or disclosed for the purpose of contacting such individual in that individual's capacity as an employee or an official of an organization and for no other purpose) to be disclosed or conveyed to one Party or any of its officers, directors, employees, financial advisors, legal counsel, representatives or agents ("Recipient") by or on behalf of the other Party ("Disclosing Party") as a result of or in conjunction with the transactions contemplated herein, and includes all such personal information disclosed to the Recipient prior to the execution of this Agreement.

Each Disclosing Party covenants and agrees to, upon request, use reasonable efforts to advise the Recipient of the purposes for which the Transferred Information was initially collected from or in respect of the individual to which such Transferred Information relates and the additional purposes where the Disclosing Party has notified the individual of such additional purpose, and where required by law, obtained the consent of such individual to such use or disclosure.

the representations and warranties of PET in this Agreement are true and correct in all respects if qualified by a reference to Material Adverse Effect and the representation and warranties of PET in this Agreement which are not qualified by a reference to Material Adverse Effect (other than the representation with respect to outstanding share capital of PET), shall be true and correct in all respects at the Expiry Time with the same force and effect as if made at such time and regardless of any reference to another time in the representations and warranties unless the failure to be true and correct has not had or would not reasonably be expected to have a Material Adverse Effect on PET (and, for this purpose, any reference to "material" or other concepts of materiality in such representations and warranties shall be ignored) as at the Expiry Time; and

all of its covenants and obligations under the Agreement have been performed or complied with in all material respects.

shall not take any action that would render, or may reasonably be expected to render, any representation or warranty made by it in this Agreement (i) that is qualified by a reference to a Material Adverse Effect misleading or untrue in any respect, or (ii) that is not qualified by a reference to a Material Adverse Effect untrue or incorrect in any respect unless the failure to be true or correct has not had or would not reasonably be expected to have a Material Adverse Effect on PET at any time prior to completion of the Offer or termination of this Agreement, whichever first occurs;

shall promptly notify Profound in writing of any Material Adverse Change affecting PET and of any change in any representation or warranty provided by PET in this Agreement which change is or may be of such a nature to render any representation or warranty , and PET shall in good faith discuss with Profound any change in circumstances (actual, anticipated, contemplated, or to the knowledge of PET, threatened) which is of such a nature that there may be a reasonable question as to whether notice need to be given to Profound pursuant to this provision;

shall use all reasonable commercial efforts to use its reasonable commercial efforts to preserve intact its business organization, assets and goodwill; to maintain its real property interests in their current state; not to take any action or omit to take any action which would render, or which reasonably would be expected to render, any representation or warranty made by it in this Agreement untrue at any time prior to the Effective Time if then made; and to promptly notify Profound in writing of any event or occurrence that would reasonably be expected to have a Material Adverse Effect on PET and of any governmental or third party complaints, investigations or hearings (or communications indicating that the same may be contemplated), provided that the foregoing shall not restrict PET from shutting-in production, entering into or crystallizing Swaps, conducting asset purchases or dispositions or selling or disposing of, in any manner, one or more direct or indirect subsidiaries of PET provided that any such transactions do not have a Material Adverse Effect on PET;

PET agrees that, for a period of five years after the Effective Time, PET will cause Profound or any successor to Profound (including any successor resulting from the winding up or liquidation or dissolution of Profound) to maintain Profound's current directors' and officers' insurance policy or an equivalent policy on a five year "trailing" or "run-off" basis subject in either case to terms and conditions no less advantageous to the directors and officers of Profound than those contained in the policy in effect on the date hereof, for all present and former directors and officers of Profound, covering claims made prior to or within five years after the Effective Time. PET shall, and shall cause Profound or any successor to Profound to, indemnify the directors and officers of Profound to the fullest extent to which PET and Profound, as the case may be, are permitted to indemnify such officers and directors under their respective charter, by-laws, Laws and contracts of indemnity.

PET covenants and agrees, to and after the Effective Time, that it will cause Profound and any successor to Profound, to honour and comply with the terms of all existing employment agreements, termination, severance and retention plans or policies of Profound all of which have been made available to PET and set out in the Disclosure Letter.

It is acknowledged that the Supporting Shareholders have or will enter into the Lock-up Agreements in their capacity as Shareholders and that having done so does not and will not derogate from the discharging of their duties as directors and/or officers of Profound. It is further acknowledged that nothing contained herein or in the Lock-up Agreements shall prevent any director or officer of Profound from discharging his legal or fiduciary obligations as a director or officer, subject to compliance with this Agreement.

The provisions of Sections 9.4, 9.5 and 9.6 are (i) intended for the benefit of the employees of Profound and all present and former directors and officers of Profound, as and to the extent applicable in accordance with their terms, and shall be enforceable by each of such persons and his or her heirs, executors administrators and other legal representatives (collectively, the "Third Party Beneficiaries") and Profound shall hold the rights and benefits of Sections 9.4, 9.5 and 9.6 in trust for and on behalf of the Third Party Beneficiaries and Profound hereby accepts such trust and agrees to hold the benefit of and enforce performance of such covenants on behalf of the Third Party Beneficiaries, and (ii) in addition to, and not in substitution for, any other rights that the Third Party Beneficiaries may have by contract or otherwise.

PET and Profound shall, as promptly as practicable hereafter, prepare and file any filings required under the Competition Act, any securities Law or any Law relating to the transactions contemplated in this Agreement.

Subject to the terms and conditions herein provided and to fiduciary obligations under applicable Law as advised by counsel in writing (which may be evidenced in Board of Directors minutes), each of the Parties hereto agrees to use all commercially reasonable efforts to take, or cause to be taken, all action and to do, or cause to be done, all things necessary, proper or advisable to consummate and make effective as promptly as practicable the transactions contemplated by this Agreement and to co-operate with each other in connection with the foregoing, including using commercially reasonable efforts (i) to obtain all necessary waivers, consents and approvals from other parties to material agreements, leases and other contracts (including, without limitation, the agreement of any Persons as may be required pursuant to any agreement, arrangement or understanding relating to Profound's operations), (ii) to obtain all necessary consents, approvals and authorizations as are required to be obtained under any federal, provincial or foreign Laws, (iii) to defend all lawsuits or other legal proceedings challenging this Agreement or the consummation of the transactions contemplated hereby, (iv) to cause to be lifted or rescinded any injunction or restraining order or other order adversely affecting the ability of the Parties to consummate the transactions contemplated hereby, (v) to effect all necessary registrations and other filings and submissions of information requested by Governmental Authorities, and (vi) to fulfill all conditions and satisfy all provisions of this Agreement and the Offer.

at any time prior to the Effective Time by mutual written consent of PET and Profound;

after the Latest Mailing Date if any condition to making the Offer is not satisfied or waived by such date (other than as a result of any breach by PET of any of its obligations hereunder);

if Profound is in default of any material covenant or obligation under this Agreement and such default is not curable or, if curable, is not cured by the earlier of the date which is five days from the date of written Notice of such breach or default and the Expiry Time; or

that is qualified by a reference to a Material Adverse Effect shall be untrue or incorrect in any respect;

that is not qualified by a reference to a Material Adverse Effect shall be untrue or incorrect in any respect unless the failure to be true or correct has not had or would not reasonably be expected to have, a Material Adverse Effect on Profound (and, for this purpose, any reference to "material" or other concepts of materiality in such representations and warranties shall be ignored); or

as to Profound's share capital on an undiluted and fully-diluted basis shall be untrue or incorrect (except for changes thereto resulting from the issuance of Common Shares under the terms of Options or Performance Warrants),

and such breach, default or inaccuracy is not curable or, if curable, is not cured by the earlier of the date which is five days from the date of written Notice of such breach, default or inaccuracy and the Expiry Time;

after the Latest Mailing Date if all of the conditions to making the Offer were satisfied on the Latest Mailing Date and PET has refused to make the Offer or does not mail the Offer by the Latest Mailing Date (other than as a result of any act of Profound or breach by Profound of any of its obligations hereunder);

if PET is in default of any material covenant or obligation under this Agreement and such default is not curable or, if curable, is not cured by the earlier of the date which is five days from the date of written Notice of such breach or default and the Expiry Time; or

that is qualified by a reference to a Material Adverse Effect shall be untrue or incorrect in any respect; or

by PET or Profound if the Effective Time has not occurred within 60 days following the Initial Expiry Time unless the failure of PET to take up and pay for the Common Shares arises as a result of the breach by Profound of any material covenant or obligation under this Agreement or as a result of any representation or warranty of Profound in this Agreement being materially untrue or incorrect provided, however, that if PET's take-up and payment for Common Shares deposited under the Offer is delayed by:

an injunction or order made by a court of competent jurisdiction or a Governmental Authority; or

PET not having obtained any Regulatory Approval that is necessary to permit PET to take up and pay for Common Shares deposited under the Offer or necessary for Profound to continue to carry on its business as currently conducted;

then, provided that such injunction or order is being actively contested or appealed by PET or Regulatory Approval is being actively sought by PET, as applicable, this Agreement shall not be terminated by Profound pursuant to this Section 11.1(d) until the earlier of: (i) the tenth Business Day following the date on which such injunction or order ceases to be in effect or such Regulatory Approval is obtained, as applicable; and (ii) 90 days following the Initial Expiry Time;

by PET if any condition of the Offer shall not be satisfied or waived at the Expiry Time of the Offer and PET shall not elect to waive such condition, unless the failure of such condition shall be due to the failure of PET to perform the obligations required to be performed by it hereunder;

by either PET or Profound if the Non-Completion Fee becomes payable (provided that for the purposes of a termination by Profound, Profound must have first paid the Non-Completion Fee);

by PET if there shall have occurred any Material Adverse Change with respect to Profound;

by Profound if there shall have occurred any Material Adverse Change with respect to PET;

by either PET or Profound if a Governmental Authority shall have issued an order, decree or ruling or taken any other action permanently restraining, enjoining or otherwise prohibiting any of the transactions contemplated by this Agreement and such order, decree, ruling or other action shall have become final and non-appealable, provided that the Party seeking to terminate this Agreement pursuant to this Section 11.1(i) shall have used all commercially reasonable efforts to remove such order, decree, ruling or injunction; or

the Board of Directors has received a Superior Proposal through no breach of Section 8.2(a) by Profound or Profound Representatives;

Profound has notified PET in writing of the existence of a Superior Proposal in accordance with this Agreement;

following receipt by PET of the notice referred to in Section 8.2(c) and a copy of the Superior Proposal, a period of at least two Business Days has elapsed;

taking into account any revised proposal made by PET pursuant to Section 8.2(c), such Superior Proposal remains a Superior Proposal; and

Profound has tendered payment of the Non-Completion Fee payable pursuant to Section 8.3 to PET or its designee.

For greater certainty, each paragraph and subparagraph of this Section 11.1 is independent of and in addition to each other paragraph and subparagraph of this Section 11.1, and may be asserted irrespective of whether any other such section or subsection may be asserted in connection with any particular event occurrence or state of facts or otherwise.

This Agreement may not be amended except by an instrument signed by each of the Parties hereto.

extend the time for the performance of any of the obligations or other acts of the other Party; or

waive compliance with any of the agreements of the other Party or with any conditions to its own obligations,

in each case only to the extent such obligations, agreements or conditions are intended for its benefit.

Any notice, consent or approval required or permitted to be given in connection with this Agreement (referred to in this Section as a "Notice") shall be in writing and shall be sufficiently given if delivered (whether in person, by courier service or other personal method of delivery), or if transmitted by facsimile or e-mail:

Any Notice delivered or transmitted to a Party as provided above shall be deemed to have been given and received on the day it is delivered or transmitted, provided that it is delivered or transmitted on a Business Day prior to 5:00 p.m. local time in the place of delivery or receipt. However, if the Notice is delivered or transmitted after 5:00 p.m. local time or if such day is not a Business Day then the Notice shall be deemed to have been given and received on the next Business Day.

Any Party may, from time to time, change its address by giving Notice to the other Parties in accordance with the provisions of this Section.

Neither this Agreement nor any rights or obligations under this Agreement shall be assignable by operation of law, amalgamation or otherwise by any Party without the prior written consent of the other Party, except that PET may assign, without being required to obtain Profound's consent, all or part of its rights or obligations hereunder to one or more of its direct or indirect wholly-owned subsidiaries, but PET shall continue to be liable to Profound as principal obligor for any default by such entities in the performance of any of PET's obligations hereunder. Subject thereto, this Agreement shall enure to the benefit of and be binding upon the Parties and their respective successors and permitted assigns. No third party shall have any rights hereunder unless expressly stated to the contrary.

The Parties shall with reasonable diligence do all such things and provide all such reasonable assurances as may be required to consummate the transaction contemplated by this Agreement, and each Party shall provide such further documents or instruments required by any other Party as may be reasonably necessary or desirable to effect the purpose of this Agreement and carry out its provisions.

Subject to Section 8.3 and Section 8.6, the Parties agree that all costs and expenses of the Parties relating to the Agreement and the transactions contemplated hereby, including legal fees, accounting fees, financial advisory fees, regulatory filing fees, stock exchange fees, all disbursements of advisors and printing and mailing costs, shall be paid by the Party incurring such expenses.

This Agreement may be executed by the Parties in counterparts and may be executed and delivered by facsimile and all such counterparts and facsimiles shall together constitute one and the same agreement.

The Parties acknowledge that the the obligations of PET hereunder shall not be personally binding upon the Administrator in its capacity as agent of Computershare Trust Company of Canada, as trustee of PET ("Computershare"), Computershare or any holder of trust units of PET, in their respective capacities as such, such that any recourse against PET, the Administrator, Computershare and any such holder, in their respective capacities as such, in any manner in respect of any indebtedness, obligation or liability of PET arising hereunder or arising in connection herewith or from the matters to which this Agreement relates, if any, including without limitation claims based in contract, on negligence, tortious behaviour or otherwise, shall be limited to, and satisfied only out of, the Trust Fund as defined in the PET Trust Indenture.

IN WITNESS WHEREOF the Parties hereto have executed this Support Agreement as of the date first written above.

The Maximum Cash Consideration and the Maximum Unit Consideration will be pro rated on each date (a "Take-Up Date") upon which PET takes up or acquires Common Shares pursuant to the Offer, Compulsory Acquisition or Subsequent Acquisition Transaction as necessary to ensure that the total aggregate consideration payable under the Offer and in any Compulsory Acquisition or Subsequent Acquisition Transaction does not exceed the Maximum Cash Consideration and the Maximum Unit Consideration. Accordingly:

the aggregate amount of cash that PET will pay as consideration for Common Shares pursuant to the Offer and any Compulsory Acquisition or Subsequent Acquisition Transaction on any Take-Up Date shall not exceed the Maximum Cash Consideration multiplied by a fraction, the numerator of which is the number of Common Shares to be taken up on such Take-Up Date and the denominator of which is the total number of outstanding Common Shares not held by PET on the date of the Offer, calculated on a fully-diluted basis (the "Maximum Take-Up Date Cash Consideration"); and

the aggregate number of PET Units that PET will issue as consideration for Common Shares pursuant to the Offer and any Compulsory Acquisition or Subsequent Acquisition Transaction on any Take-Up Date shall not exceed the Maximum Unit Consideration multiplied by a fraction, the numerator of which is the number of Common Shares to be taken up on such Take-Up Date and the denominator of which is the total number of outstanding Common Shares not held by PET on the date of the Offer, calculated on a fully-diluted basis (the "Maximum Take-Up Date Unit Consideration").

The actual consideration to be received by a Shareholder electing the cash alternative (a "Cash Electing Shareholder") and a Shareholder electing (or deemed to be electing) the unit alternative (a "Unit Electing Unitholder") is subject to the following:

if, on any Take-Up Date, the aggregate cash consideration that would otherwise be payable by PET to Cash Electing Shareholders in respect of their Common Shares to be taken up on such Take-Up Date exceeds the Maximum Take-Up Date Cash Consideration, then the Maximum Take-Up Date Cash Consideration will be prorated among the Cash Electing Shareholders such that each Cash Electing Shareholder will receive an amount equal to the amount of the cash sought by such Cash Electing Shareholder multiplied by a fraction, the numerator of which is the Maximum Take-Up Date Cash Consideration and the denominator of which is the aggregate amount of the cash consideration sought by all Cash Electing Shareholders on such Take-Up Date, and each such Cash Electing Shareholder will receive the balance of the consideration to which they are entitled in the form of a number of PET Units calculated by dividing such balance by $3.40, rounded down to the nearest whole number (with cash paid in lieu of any fractional PET Unit); and

if, on any Take-Up Date, the number of PET Units that would otherwise be issuable to Unit Electing Shareholders in respect of their Common Shares to be taken up on such Take-Up Date exceeds the Maximum Take-Up Date Unit Consideration, then the Maximum Take-Up Date Unit Consideration will be prorated among the Unit Electing Shareholders such that each Unit Electing Shareholder will receive a number of PET Units equal to the number of PET Units sought by such Unit Electing Shareholder multiplied by a fraction (rounded to four decimal places), the numerator of which is the Maximum Take-Up Date Unit Consideration and the denominator of which is the aggregate number of PET Units sought by all Unit Electing Shareholders in respect of

their Common Shares to be taken up on such Take-Up Date, rounded down to the nearest whole number (with cash paid in lieu of any fractional PET Unit) and each such Unit Electing Shareholder will receive the balance of the consideration to which they are entitled in cash, calculated by multiplying the number of PET Units to which they were otherwise entitled but did not receive by $3.40 (rounded down to the nearest $0.01).

For the purposes of the calculations, if any Shareholder elects more than one consideration alternative, such Shareholder will be considered as a separate Shareholder with respect to each consideration alternative elected. Any cash paid in lieu of any fractional PET Unit hereunder shall be in addition to and shall not reduce the Maximum Cash Consideration.

Subject to the provisions of the Agreement, PET shall have the right to withdraw the Offer or terminate the Offer and shall not be required to take up, purchase or pay for, and shall have the right to extend the period of time during which the Offer is open and postpone taking up and paying for, any Common Shares deposited under the Offer unless all of the following conditions are satisfied or waived by PET at or prior to the Expiry Time:

there shall have been deposited under the Offer and not withdrawn at least 66 2/3% of the Common Shares outstanding on a fully-diluted basis (excluding any Common Shares issued or issuable upon conversion of the Special Warrants) other than any Common Shares held at the date of the Offer by or on behalf of PET or its Affiliates or any Common Shares issued or issuable upon conversion of the Special Warrants (the "Minimum Tender Condition");

all requisite Regulatory Approvals, including the Competition Act Approval, shall have been obtained on terms and conditions satisfactory to PET in its sole discretion, acting reasonably;

PET shall have determined in its discretion, acting reasonably, that no act, action, suit or proceeding shall have been threatened or taken before or by any Governmental Authority, whether or not having the force of Law, and no Law shall have been proposed, enacted, promulgated or applied, in either case:

to cease trade, enjoin, prohibit or impose material limitations, damages or conditions on the purchase by or the sale to PET of the Common Shares or the right of PET to own or exercise full rights of ownership of the Common Shares;

which, if the Offer were consummated, would reasonably be expected to have a Material Adverse Effect on PET or Profound; or

which would materially and adversely affect the ability of PET to proceed with the Offer (or any Compulsory Acquisition or Subsequent Acquisition Transaction) and/or take up and pay for any Common Shares deposited under the Offer;

there shall not exist any prohibition at Law against PET making the Offer or taking up and paying for any Common Shares deposited under the Offer or completing any Compulsory Acquisition or Subsequent Acquisition Transaction;

there shall not exist or have occurred, in the judgment of PET, acting reasonably, a Material Adverse Change in respect of Profound;

that are qualified by a reference to a Material Adverse Effect shall be true and correct in all respects; and

that are not qualified by a reference to a Material Adverse Effect (other than with respect to outstanding share capital (on an undiluted and fully diluted basis) which shall be true and correct in all respects except for changes thereto resulting from the issuance of Common Shares under the terms of the Options and Performance Warrants) shall be true and correct in all respects unless the failure to be true or correct has not had or would not reasonably be expected to have a Material Adverse Effect; and

Profound shall have observed and performed its covenants in the Agreement in all material respects to the extent that such covenants were to have been observed or performed by Profound at or prior to the Expiry Time;

the Lock-up Agreements shall have been complied with and shall not have been terminated;

the Area of Exclusion Agreements shall have been complied with and shall not have been terminated;

except as set forth in the Disclosure Letter, all outstanding Options or Performance Warrants, or any other rights or entitlements granted to purchase or otherwise acquire authorized and unissued Common Shares shall have been exercised in full, converted, repurchased as permitted by the Agreement or irrevocably released, surrendered or waived;

there shall be no written or oral consulting or management agreements, or contracts of employment entered into with any parties or employees employed by Profound which are not terminable on giving of reasonable notice in accordance with applicable Laws and the payment of any amount required thereunder which payments shall not exceed in the aggregate the sum of $1,450,000;

there shall be no greater than 40,711,741 Common Shares issued and outstanding, on a fully diluted basis, after taking account of any such Common Shares issued or to be issued upon the exercise or surrender of Options or Performance Warrants, as contemplated in paragraph (k) of this Schedule "B"; and

the aggregate of Profound's net debt (being bank debt plus any net working capital deficiency or less any working capital surplus) at March 26, 2009 shall not exceed $61,500,000, excluding the reasonable fees and expenses of Profound incurred in connection with the Offer (including, but not limited to, the payment of all Employee Obligations and financial advisor expenses) which shall not, in the aggregate, exceed $2,500,000.

The foregoing conditions are for the exclusive benefit of PET and may be asserted by PET regardless of the circumstances giving rise to such assertion (including any action or inaction by PET or any of its Affiliates) giving rise to any such condition. PET may, in PET's sole discretion, waive any of the foregoing conditions, in whole or in part, at any time and from time to time, both before and after the Expiry Time, without prejudice to any other rights which PET may have. The failure by PET at any time to exercise any of the foregoing rights will not be deemed to be a waiver of any such right and each such right shall be deemed to be an ongoing right which may be assessed at any time and from time to time. For greater certainty, each of the conditions set out in this Schedule "B" is independent of and in addition to each other condition set out in this Schedule "B" and may be asserted irrespective of whether any other condition may be asserted in connection with any particular event, occurrence or state of facts or otherwise.

PET has been duly created and is a valid and subsisting trust under the Laws of Alberta and has the requisite trust authority and power to carry on its business as it is now being conducted. The Administrator is and Offerco will be a corporation duly incorporated and organized and validly existing under the Laws of Alberta and has the requisite corporate power and authority to carry on its business as it is now being conducted. Each of PET and the Administrator is and Offerco will be duly registered to do business and is in good standing in each jurisdiction in which the character of its properties, owned or leased, or the nature of its activities make such registration necessary, except where failure to be so registered or in good standing would not have a Material Adverse Effect on PET.

PET has the requisite trust authority, and the Administrator has the requisite corporate authority, to enter into this Agreement and to carry out their respective obligations hereunder. The execution and delivery of this Agreement and the consummation of the transactions contemplated hereby have been duly authorized by the board of directors of the Administrator, and no other corporate or trust proceedings on the part of PET or the Administrator are necessary to authorize this Agreement and the transactions contemplated hereby. This Agreement has been duly executed and delivered for and on behalf of PET and by the Administrator and constitutes the legal, valid and binding obligation of PET and the Administrator enforceable against them in accordance with its terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and other Laws relating to or affecting creditors' rights generally, and to general principles of equity.

None of the execution and delivery of this Agreement by PET or the Administrator, the consummation of the transactions contemplated hereby or compliance by PET or the Administrator with any of the provisions hereof will: (i) violate, conflict with, or result in breach of any provision of, require any consent, approval or notice under, or constitute a default (or an event which, with notice or lapse of time or both, would constitute a default) or result in a right of termination or acceleration under, or result in a creation of any Encumbrance upon any of the properties or assets of PET or the Administrator, or any of their respective subsidiaries, under any of the terms, conditions or provisions of (x) its constating documents or (y) any note, bond, mortgage, indenture, loan agreement, deed of trust, agreement, lien, contract or other material instrument or obligation to which PET, the Administrator or any of their subsidiaries is a party or to which any of them, or any of their respective properties or assets, may be subject or by which PET, the Administrator or any of their subsidiaries is bound; (ii) violate any judgement, ruling, order, writ, injunction, determination, award, decree, statute, ordinance, rule or regulation applicable to PET, the Administrator or any of their subsidiaries; or (iii) cause the suspension or revocation of any authorization, consent, approval or licence currently in effect (except, in the case of each of clauses (i), (ii) and (iii) for such violations, conflicts, breaches, defaults, terminations, suspensions or revocations which, or any consents, approvals or notices which if not given or received, would not have a Material Adverse Effect on PET or have a material adverse effect on the ability of PET to consummate the transactions contemplated hereby).

Other than in connection with or in compliance with the provisions of securities Laws, the requirements of the Toronto Stock Exchange and the Competition Act: (i) there is no legal impediment to PET's consummation of the transactions contemplated by this Agreement; and (ii) no filing or registration with, or authorization, consent or approval of, any domestic or foreign public body or authority is necessary by PET in connection with the making or the consummation of the Offer, except for such filings or registrations which, if not made, or for such authorizations, consents or approvals, which, if not received, would not have a material adverse effect on the ability of PET to consummate the transactions contemplated hereby.

PET has currently available to it and will have at the Effective Time financial resources sufficient to fund the consideration payable by it to the Shareholders pursuant to the Offer.

Although it does not warrant title, Profound is not aware of any defects, failures or impairments to the title to its oil and gas properties, whether or not an action, suit, proceeding or inquiry is pending or threatened and whether or not discovered by any third party which in the aggregate could reasonably be expected to have a Material Adverse Effect on Profound.

All agreements, permits, licences, regulatory approvals, plans, certificates and other rights and authorizations material to the conduct of the business of Profound are disclosed in the Disclosure Letter and are valid and subsisting and Profound is not in material default under any such agreements, permits, licences, Regulatory Approvals, plans, certificates and other rights and authorizations. For the purposes of this Section 32, any contract or agreement pursuant to which Profound will, or may reasonably be expected to, expend more than an aggregate of $150,000 or receive or be entitled to receive revenue of more than $150,000 in either case in the next 12 months, or is out of the ordinary course of business of Profound, shall be considered to be material.

To the knowledge of Profound, Profound has not withheld from PET any material information or documents concerning Profound or its assets or Liabilities during the course of PET's review of Profound and its assets.

Profound is a "reporting issuer" or the equivalent thereof not in default under the securities legislation of each of the provinces of British Columbia, Alberta, Saskatchewan, Manitoba, Ontario, Quebec and New Brunswick.

As of the date of this Agreement, Profound's daily production is not less than 3,000 boe/d.

As at March 26, 2009, Profound's net debt (being bank debt and net working capital deficiency) does not exceed $61,500,000.

No event of default or breach of any covenant has occurred under Profound's existing banking and lending agreements. Profound has provided PET with true and complete copies of any documentation respecting all of Profound's existing banking and lending agreements.

Profound is not a party to or bound by any agreement of guarantee, indemnification (other than indemnification of directors and officers in accordance with the by-laws of Profound and applicable Laws and other than standard indemnities in favour of purchasers of assets in purchase and sale agreements and underwriters and agents in connection with offerings of securities, Profound's registrar and transfer agent, indemnities and guarantees in favour of Profound's bankers and indemnities to support Profound's obligations pursuant to agreements entered into in the ordinary course of business), or any other like commitment of the obligations, Liabilities (contingent or otherwise) of indebtedness of any other person.

No action or proceeding has been commenced or filed by or against Profound or which seeks or may lead to receivership, bankruptcy, a commercial proposal or similar proceeding of Profound, the adjustment or compromise of claims against it or the appointment of a trustee, receiver, liquidator, custodian or other similar officer for Profound or any portion of its assets. No such action or proceeding has been authorized or is being considered by or on behalf of Profound and no creditor or equity securityholder of Profound has threatened to commence or advised that it may commence, any such action or proceeding.

Profound has not made, nor is it considering making, an assignment for the benefit of its creditors, and has not requested, nor is it considering requesting, a meeting of its creditors to seek a reduction, compromise, composition or other accommodation with respect to its indebtedness.

Profound has not entered into any agreements or made any covenants with any parties with respect to the issuance of "flow-through" shares or the incurring and renunciation of Canadian exploration expense or

Canadian development expense, which amounts have not been fully expended and renounced as required thereunder.

Profound's Tax Pools on a consolidated basis were not less than $200.8 million in the aggregate as at December 31, 2008, comprised approximately as follows:

and Profound has no reason to believe that its Tax Pools on a consolidated basis were materially less on the date hereof than as set forth above.

To the best of Profound's knowledge, all ad valorem, property, production, severance and similar taxes and assessments based on, or measured by, the ownership of the Profound Interests or the production of crude oil, natural gas and natural gas liquids from the Profound Interests, or the receipt of proceeds from them, and all royalties and rentals accruing prior to the Effective Time, that are payable by Profound with respect to the Profound Interests will at the Effective Time have been properly paid or will be paid in a timely fashion.

Other than as disclosed in the Disclosure Letter, Profound has not entered into any third party processing or transportation agreements or any obligations to deliver sales volumes to any other person and has not entered into any marketing arrangements or agreements having any fixed price, term or delivery obligations.

Other than those Swaps disclosed in the Financial Statements or in the Disclosure Letter, Profound currently has no outstanding Swaps.

The only directors, officers or employees of Profound entitled to receive a "collateral benefit" (as such term is defined in Multilateral Instrument 61-101), directly or indirectly, in connection with the Offer are William T. Davis and Nicholas Wemyss.

Profound is a "foreign private issuer" as defined in Rule 3b-4 under the Exchange Act.

There is no class of securities of Profound which is registered or required to be registered pursuant to Section 12 of the Exchange Act, nor is Profound subject to any reporting obligation pursuant to Section 15(d) of the Exchange Act. Profound is not, and has never

been, subject to any requirement to register any class of its equity securities pursuant to Section 12(g) of the Exchange Act.

Profound is not an investment company registered or required to be registered under the United States Investment Company Act of 1940, as amended.

U.S. Holders do not, and as of a date no more than 60 days before or 30 days after the public announcement of the Offer will not, hold more than 10% of the Common Shares, as calculated under the Exchange Act. Profound does not, and will not, know or have any reason to know before the public announcement of the Offer, that U.S. Holders hold more than 10% of the Common Shares.

The Common Shares have not been traded on any national securities exchange (as such term is used in the Exchange Act) in the United States during the past 12 calendar months, and will not be so traded prior to the commencement of the Offer. The average daily trading volume of the Common Shares in the United States for a recent 12 month period ending no more than 60 days before the public announcement of the Offer did not, and, if applicable, will not, exceed 10 percent of the average daily trading volume of the Common Shares on a worldwide basis for the same period.

Profound, including all entities "controlled by" Profound for purposes of the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, does not hold assets located in the United States with a fair market value in excess of U.S. $10 million in the aggregate and, during the 12 month period ended December 31, 2008, did not make sales in or into the United States in excess of U.S. $10 million in the aggregate. For purposes of the foregoing, the term "United States" shall include the several states, territories, possessions, and commonwealths of the United States, and the District of Columbia.

The "primary trading market" (as such term is used in Rule 12h-6(f)(5) under the Exchange Act) for the Common Shares is outside the United States. Profound's most recent Annual Information Form filed on SEDAR does not indicate that U.S. Holders hold more than 10% of the Common Shares.

Offer by Paramount Energy Trust to Purchase all of the Common Shares of Profound Energy Inc.

Reference is made to the support agreement dated March 30, 2009 (the "Support Agreement") among Paramount Energy Trust ("PET"), Paramount Energy Operating Corp. and Profound Energy Inc. ("Profound") pursuant to which PET has agreed that PET or an affiliate of PET shall make an offer to purchase all of the issued and outstanding common shares of Profound and all shares of Profound that may be issued after the date hereof upon the exercise or surrender of outstanding Options and Performance Warrants (collectively, the "Profound Shares"). All capitalized terms referred to herein shall have the meanings attributed thereto in the Support Agreement.

This letter agreement sets out the terms and conditions upon which you have agreed, among other things, to support the Offer and deposit under the Offer, all of the Profound Shares that are, or will be, beneficially owned, directly or indirectly, by you or otherwise under your control or direction (collectively, the "Subject Shares").

PET understands that as of the date hereof you (the "Selling Shareholder") or your Affiliates beneficially own, directly or indirectly, or exercise control or direction over, the number of Profound Shares set forth in your acceptance at the end of this letter agreement.

Subject to Section 2 hereof, by the acceptance of this letter agreement, the Selling Shareholder hereby agrees, subject to the terms of paragraph 6 of this letter agreement, from the date hereof until the completion of the Offer:

not to sell, assign, convey or otherwise dispose of any of the Subject Shares and not to permit any Affiliate of such Selling Shareholder to sell, assign, convey or otherwise dispose of any Profound Shares, except as contemplated by the Support Agreement;

unconditionally and irrevocably, subject only to Section 2 hereof, to accept and to cause any Affiliate of such Selling Shareholder to unconditionally and irrevocably accept the Offer made by PET by depositing the Subject Shares (including any Profound Shares hereafter acquired pursuant to the exercise or surrender of any Options, Performance Warrants or other securities convertible into, or exchangeable for, Profound Shares) by such Selling Shareholder or Affiliate prior to the expiry of the Offer and in accordance with the terms and conditions of the Offer at least two Business Days prior to the Initial Expiry Time;

to exercise, or to surrender to Profound, all Options and Performance Warrants held by the Selling Shareholder at least two Business Days prior to the Initial Expiry Time,

provided that such exercise or surrender may be conditional upon the take-up by PET of Profound Shares under the Offer;

not to exercise, and to cause any Affiliate of such Selling Shareholder not to exercise, any statutory or other rights of withdrawal with respect to any of the Subject Shares once deposited pursuant to the Offer (or otherwise disposed of) unless this letter agreement is terminated prior to PET taking up the Profound Shares under the Offer;

not to exercise any securityholder rights or remedies available at common law or pursuant to the ABCA or applicable securities legislation to delay, hinder, prevent, interfere with or challenge the Offer in any manner;

to comply with the terms of Section 8.2 of the Support Agreement which the Selling Shareholder agrees, by execution hereof, to be bound by if the Selling Shareholder is an officer, director, employee, representative or agent of Profound; and

to not take any action, directly, or indirectly, which may in any way adversely affect the success of the Offer or the purchase of any Profound Shares under the Offer.

Notwithstanding Section 1 above, if, during the time that the Offer is outstanding, a Superior Proposal is made to all of the holders of Profound Shares and the fee contemplated by Section 8.3 of the Support Agreement has been paid to PET, the Selling Shareholder shall not be required to deposit the Subject Shares to the Offer or may withdraw the Subject Shares deposited to the Offer, as the case may be, in order to permit the Selling Shareholder to deposit the Subject Shares to the Superior Proposal.

such Selling Shareholder is duly authorized to execute and deliver this letter agreement and this letter agreement is a valid and binding agreement, enforceable against such Selling Shareholder in accordance with its terms; and neither the execution of this letter agreement by the Selling Shareholder nor the consummation by such Selling Shareholder of the transactions contemplated hereby will constitute a violation of or default under, or conflict with, any contract, commitment, agreement, understanding, arrangement or restriction of any kind to which such Selling Shareholder is or will be a party and by which such Selling Shareholder will be bound at the time of such consummation;

such Selling Shareholder beneficially owns, directly or indirectly, or exercises control or direction over, the Profound Shares set forth in the form of acceptance attached hereto and such Selling Shareholder has and at the time that such shares are taken up pursuant to the Offer such Selling Shareholder will have (without exception) valid and marketable title to such Profound Shares free and clear of all Encumbrances (except for the obligations of the Selling Shareholder under this letter agreement) and the transfer of such Profound Shares to PET under the Offer will pass good and marketable title to such Profound Shares, free and clear of all Encumbrances; and

all of the representations and warranties contained in this paragraph 3 shall be valid and true as if recited and repeated at length as at the completion of the Offer.

PET hereby represents and warrants to and covenants with the Selling Shareholder that:

PET is duly authorized to execute and deliver this letter agreement and this agreement, upon acceptance by the Selling Shareholder, will be a valid and binding agreement, enforceable against PET in accordance with its terms; and neither the execution of this letter agreement by PET nor the consummation by PET of the transactions contemplated hereby will constitute a violation of or default under, or conflict with, any contract, commitment, agreement, understanding, arrangement or restriction of any kind to which PET is a party and by which PET is bound; and

all of the representations and warranties contained in this paragraph 4 shall be valid and true as if recited and repeated at length as at the completion of the Offer.

PET shall make the Offer in accordance with the terms and conditions of the Support Agreement and shall comply with the terms and conditions of Article 2 thereof in respect of the Offer.

PET shall, subject to the satisfaction or waiver of the conditions set forth in the Offer, take up and pay for all of the Subject Shares deposited pursuant to the Offer, all in accordance with the terms and conditions of the Offer and the provisions of the Support Agreement.

PET shall use its reasonable commercial efforts to complete the Offer in accordance with, and subject to, the terms and conditions of the Support Agreement.

Nothing herein shall restrict or limit the actions of any person required to be taken in the discharge of his fiduciary duties as a director or officer of Profound when acting in the capacity of a director or an officer of Profound, provided that nothing in this paragraph 6 will be deemed to give rise to a right to terminate this letter agreement except in accordance with paragraph 8.

PET and the Selling Shareholder agree to pay their own respective expenses incurred in connection with this letter agreement. Each of the parties hereto agrees to indemnify the other against any claim for a finder's fee or other compensation validly made by any broker which has an agreement with such indemnifying party for the payment of such fee or compensation.

It is understood and agreed that the respective rights and obligations hereunder of PET and the Selling Shareholder shall cease and this letter agreement shall terminate:

the date this letter agreement is terminated by mutual written consent of PET and the Selling Shareholder;

if PET decreases the consideration offered pursuant to the Offer or otherwise modifies or amends the Offer in a manner materially adverse to holders of Profound Shares, provided that, for greater certainty, an extension, or waiver, in whole or in part, of any conditions under the Offer shall not constitute a modification or amendment of the Offer in a manner materially adverse to holders of Profound Shares;

in the event that the Support Agreement is terminated pursuant to Article 11 thereof.

In the event of termination of this letter agreement, the Selling Shareholder may withdraw all of the Profound Shares deposited in accordance with the terms and conditions of the Offer, this letter agreement shall forthwith be of no further force and effect, except as set forth in paragraph 7, and there shall be no liability on the part of either the Selling Shareholder or PET, except to the extent that either such party is in default of its obligations herein contained.

Except as expressly set forth herein, this letter agreement constitutes the whole of the agreement between the parties and may not be modified, amended, altered or supplemented except upon the execution and delivery of a written agreement executed by the parties hereto.

Except as expressly set forth herein, no party to this letter agreement may assign any of its rights or obligations under this letter agreement without the prior written consent of the other party except that PET may assign its rights and obligations under this letter agreement to any of its Affiliates, to the extent permitted by the Support Agreement, but no such assignment shall relieve PET of its obligations hereunder.

Prior to first public disclosure of the existence and terms and conditions of this letter agreement, none of the parties hereto shall disclose the existence of this letter agreement, or any details hereof, to any person other than the Selling Shareholder's advisors, Profound and Profound's directors and officers, without the prior written consent of the other parties hereto, except to the extent required by law. The existence and terms and conditions of this letter agreement may be disclosed by PET and Profound in the press release issued in connection with the execution of the Support Agreement, the Bid Circular and the Directors' Circular. The Selling Shareholder consents to the public filing of this Agreement on SEDAR.

This letter agreement will be binding upon and enure to the benefit of PET, the Selling Shareholder and their respective heirs, executors, administrators, personal representatives, successors and permitted assigns.

This letter agreement shall be governed by and construed in accordance with the laws of the Province of Alberta and the federal laws of Canada applicable therein and each of the parties hereto irrevocably attorns to the jurisdiction of the courts of the Province of Alberta.

If any provision of this letter agreement is determined to be void or unenforceable, in whole or in part, it shall be severable from all other provisions hereof and shall be deemed not to affect or impair the validity of any other provision hereof and each such provision is deemed to be separate and distinct.

The parties hereto agree that irreparable damage would occur in the event that any of the provisions of this letter agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the parties shall be entitled to an injunction or injunctions to prevent breaches of this letter agreement and to enforce specifically the terms and provisions hereof in any court of the Province of Alberta having jurisdiction, this being in addition to any other remedy to which such party is entitled at law or in equity.

For a period of eighteen (18) months from the Effective Time, the Grantors will not acquire or cause to be acquired, and will be liable to POT for ensuring that no Related Person acquires or causes to be acquired,

whether directly or indirectly, from any Person, other than with or from Profound, PET or their respective Affiliates, any Excluded Interest, whether as an individual or as a partner, co-venturer, co-owner, investor, lender or financier of or with any other Person, as the case may be, or in any other capacity whatsoever.

If a Grantor (hereinafter referred to as a "Defaulting Party"), or Related Person of a Grantor, acquires any Excluded Interest during the period set forth in Section 2.1, the following provisions shall apply:

The Defaulting Party shall forthwith notify (the "Excluded Interest Notice") the Grantee of the terms on which the Defaulting Party acquired such Excluded Interest including the cash price paid to acquire such Excluded Interest and if not cash, the Defaulting Party's bona fide estimate of the value, in cash, of the consideration paid in connection with the acquisition of the Excluded Interest.

If the Grantee is of the opinion that the Defaulting Party's estimate of non-cash consideration paid or payable in connection with the acquisition of the Excluded Interest exceeds the value thereof, it shall notify (the "Response Notice") the Defaulting Party within 15 Business Days of receiving the Excluded Interest Notice specifying its estimate as to the value of the Excluded Interest.

In the event the Grantee provides the Response Notice, the Defaulting Party and the Grantee shall attempt to agree on a value. If an agreement on the value of the Excluded Interest cannot be reached within 10 Business Days of the Response Notice being given by the Grantee, the value of the Excluded Interest acquired shall be determined as follows:

the Defaulting Party and Grantee shall forthwith jointly retain Sproule Associates Limited (the "Valuator") to determine the value of the Excluded Interest;

the Valuator, in accordance with good engineering and evaluation practices, shall determine a value for the Excluded Interest from and based only upon the written statements submitted by the Defaulting Party and the Grantee, which written statements shall be submitted to the Valuator within 5 Business Days of the Valuator being retained;

the value determined by the Valuator shall be the value of the Excluded Interest for the purposes of this Agreement; and

such evaluation must be completed within 20 Business Days from the date of the Valuator being retained.

The fees and other costs to be paid to the Valuator in respect to the services performed by it shall be borne entirely by the Defaulting Party should the value set forth by the Defaulting Party in its Excluded Interest Notice exceed the value determined by the Valuator by 10% or more. In all other circumstances the fees and costs to be paid to the Valuator shall be borne entirely by the Grantee.

For the period ending 30 Business Days (the "Due Diligence Period") after the later of: (i) receipt of the Excluded Interest Notice; or (ii) the determination of the value of the

Excluded Interest pursuant to Subsection 2.2(c) hereof, as applicable, the Grantee shall be entitled to physically inspect the interest and to review the Defaulting Party's files in respect of the Excluded Interest, and the Defaulting Party shall provide reasonable access to the Grantee to complete its inspection and review.

Prior to the expiry of the Due Diligence Period, the Grantee may elect to acquire or assume such Excluded Interest by notifying each Defaulting Party of its election.

Closing of the acquisition shall occur on the 20th Business Day following the date the Grantee makes its notification pursuant to Subsection 2.2(e).

At the closing of the acquisition of the Excluded Interest, the Grantee shall pay the Defaulting Parties an amount equal to the value of the Excluded Interest as determined pursuant to this Section 2.2 (which amount shall not include any interest on such value), and the Grantee shall be entitled at no cost to receive a conveyance of title to the Excluded Interest and to be novated into any agreements governing the same into which any Defaulting Party have been or are being novated, and to receive from such Defaulting Party: (i) representations and warranties as to the absence of any adverse claims, liens or encumbrances created by, through or under the Defaulting Party subsequent to the date of acquisition of the Excluded Interest by the Defaulting Party; and (ii) a restatement for the benefit of the Grantee of all representations, warranties and covenants given by the third parties from who the Excluded Interest was acquired.

The obligation of a Defaulting Party to convey or cause the conveyance of an Excluded Interest to the Grantee pursuant to Section 2.2 shall be subject in all events to compliance with applicable rights of first refusal and other pre-emptive rights ("ROFRs"). For greater certainty, if a ROFR is triggered as the result of a proposed conveyance pursuant to this Section 2.2, the required ROFR notice shall be sent to the third parties entitled to the ROFR using the Defaulting Party's and the Grantee's agreed value, or the Valuator's determined value, as applicable, for the Excluded Interest that is subject to the ROFR and if one or more of these third parties exercise the ROFR, the Excluded Interest shall be conveyed to such third party or parties and the Defaulting Party shall be entitled to retain all proceeds from such conveyance.

Notwithstanding the foregoing, if a Defaulting Party acquires any Excluded Interest consisting solely of rights and/or obligations for which no consideration was paid by the Defaulting Party, the Defaulting Party shall be obligated in respect of such Excluded Interest only to forthwith offer to the Grantee for the Grantee to accept an assignment of such rights and/or obligations from the Defaulting Party, without the payment of any consideration to the Defaulting Party.

For greater certainty, it is the intention of the Parties that should the Grantee elect pursuant to this Clause 2.2 to acquire an Excluded Interest which has been acquired by a Defaulting Party, it shall be entitled to do so on terms no more or less favourable than those by which the Defaulting Party acquired such Excluded Interest.

Sections 2.1 and 2.2 hereof shall have no application to the acquisition of voting securities (as defined in the Securities Act (Alberta)) of a Person who owns (or acquires) an Excluded Interest, provided that the

Grantors (and their respective Affiliates and Related Persons), taken together, do no hold 10% or more of the issued and outstanding voting securities of that Person.

For a period of eighteen (18) months from the Effective Time, the Grantors will not disclose, divulge, reveal, report, publish or transfer to any Person, other than the Grantee, Profound or their Affiliates or make use of in the role of a consultant to, or employee of, any other Person, any Confidential Information, excepting only disclosure of Confidential Information as may be compelled by applicable Laws or may be consented to in writing by the Grantee. Each Grantor further acknowledges and agrees that the Confidential Information:

is or may be secret and not known within the oil and gas industry or to its competitors;

was developed by Profound, PET or their Affiliates or for and on behalf of Profound, PET or their Affiliates through substantial expenditures of time, effort and money;

gives or may give Profound, PET or their Affiliates a competitive advantage over other Persons (including the Grantors) who do not know or use the Confidential Information;

is of such value and nature as to make it reasonable and necessary to protect and preserve the confidentiality and secrecy of the Confidential Information; and

is a valuable and unique asset of Profound, PET or their Affiliates, as applicable.

The Grantors further acknowledge and agree that the use or disclosure of the Confidential Information in contravention of this Agreement would cause substantial injury and losses to the Grantee and that the Confidential Information is and shall remain in all respects the exclusive property of Profound, PET or their Affiliates, as applicable.

Except as expressly contemplated in the Support Agreement (or documents delivered thereto) the Grantors shall not remove from any of the business premises or business locations of Profound or its Affiliates any files, records, documents, information, data and similar items relating to or evidencing any of the Confidential Information, except with the prior written consent of the Grantee.

If any Grantor is compelled by law or by a court of competent jurisdiction or regulatory authority to produce or divulge any of the Confidential Information to any Person whatsoever, such Grantor shall immediately notify the Grantee of such requirement and shall promptly hand deliver a copy of any written material or requests relating thereto to the Grantee and, for this purpose, such Grantor irrevocably nominates and appoints the Grantee (including any legal representatives retained by the Grantee) as the true and lawful representative of such Grantor to act in such Grantor's name, place and stead to perform any and all acts as the Grantor might perform or which may be desirable to be

performed to defend and protect against the disclosure of any of the Confidential Information.

If any term or provision herein is determined to be void or unenforceable in whole or in part, it shall be deemed to be severable and it shall not affect or impair the enforceability or validity of any other covenant or provision of this Agreement or any part hereof.

This Agreement shall be governed and interpreted and may be enforced in accordance with the laws of the Province of Alberta and the federal laws of Canada applicable therein and each Grantor hereby submits and attorns to the non-exclusive jurisdiction of the courts of Alberta.

Each Grantor acknowledges and agrees that the foregoing agreements are being relied upon by PET and its Affiliates as an integral part of and as a material inducement to entering into the Support Agreement and that the foregoing agreements are reasonable and will not interfere with the Grantor's or any Related Person's ability to pursue other business ventures or a proper livelihood. Each Grantor represents and warrants that it is legally free to make and perform this Agreement, that it has had access to independent legal representation for the purposes of entering into this Agreement, that it has no obligation to any other Person or entity that would affect or conflict with any of its obligations under this Agreement and that the strict performance of its obligations will not violate any law, regulation, order, decree or contractual obligation by which it is bound.

Each Grantor acknowledges and agrees that the Grantee shall suffer irreparable and substantial harm in the event that any Grantor or any Related Person breaches this Agreement and that monetary damages will be inadequate to compensate the Grantee for such breach. Accordingly, in the event of a breach or threatened breach by any Grantor or any Related Person of any of the provisions of this Agreement, the Grantee shall, in addition to and not in limitation of any other rights, remedies or damages available to the Grantee, at law or in equity, be entitled to seek an interim injunction, interlocutory injunction and permanent injunction in order to prevent or to restrain any such breach by such Grantor or such Related Person of this Agreement.

Each Grantor shall, on a several and not joint basis, indemnify the Grantee for, and shall save the Grantee harmless from any and all losses, damages, costs or expenses whatsoever (including all legal and other professional fees and disbursements, on a full indemnity basis) incurred or suffered by the Grantee as a result of the breach by that particular Grantor (or any Related Person to that Grantor) of this Agreement.

The obligations and liabilities of the Grantors, including without limitation those in Section 4.5, are several and not joint, and each particular Grantor shall only have liability hereunder, including under an indemnity, as a result of a breach by it (or any Related Person to that Grantor) and shall not be liable for any breach by the other Grantor unless and to the extent also a breach of such Grantor (or any Related Person to the Grantor).

Each Grantor further agrees that if a Related Person of a Grantor shall breach any of the obligations undertaken in this Agreement, the Grantee shall be entitled to an accounting for and a repayment of all profits, compensation, royalties, commissions, remunerations and other benefits whatsoever which that Grantor (or Related Person of that Grantor) shall directly or indirectly realize or may realize from or relating to any such breach, all of which are hereby assigned to the Grantee, in addition to and not in limitation of any other rights, but in no event in duplication to, remedies or damages available to the Grantee, at law or in equity.

No failure or delay by the Grantee in exercising any right, power or privilege under this Agreement shall operate as a waiver thereof, nor shall any single or partial exercise thereof preclude any other or future exercise of any right, power or privilege hereunder.

Notwithstanding anything to the contrary contained herein, all notices required or permitted hereunder shall be in writing. Any notice to be given hereunder shall be deemed to be properly provided if delivered in any of the following modes:

Personally, by delivering the notice to the party on which it is to be served at that party's address for notices as set forth in Section 4.10. Personally delivered notices shall be deemed to be received by the addressee when actually delivered as aforesaid; provided that, such delivery shall be during normal business hours on any Business Day. If a notice is not delivered on a Business Day or is delivered after the addressee's normal business hours, such notice shall be deemed to have been received by such party at the commencement of the addressee's first Business Day next following the time of the delivery; or

by facsimile (or by any other like method by which a written message may be sent) directed to the party on which it is to be delivered at that party's facsimile number as set forth in Section 4.10. A notice so served shall be deemed to be received by the addressee when transmitted by the party delivering the notice (provided such party obtains confirmation from its facsimile of successful transmission), if transmitted during the addressee's normal business hours on any Business Day, or at the commencement of the next ensuing Business Day following transmission if such notice is not transmitted on a Business Day or is transmitted after the party's normal business hours.

The address and facsimile number for delivery of notices hereunder of each of the parties shall be as follows:

A party may change its address and facsimile number for delivery by notice to the other party in the manner set forth herein, and such changed address for notices thereafter shall be effective for all purposes of this Agreement.

This Agreement shall enure to the benefit of the Grantee and its successors and assigns and shall be binding upon each of the Grantors and their respective successors and assigns.

This Agreement shall terminate and be of no further force or effect in the event the Support Agreement is terminated in accordance with its terms without PET or one of its Affiliates having taken up and paid for any shares of Profound pursuant thereto.

The parties acknowledge that the the obligations of the Grantee hereunder shall not be personally binding upon Paramount Energy Operating Corp. (the "Trustee") in its capacity as trustee of the Grantee or any beneficiary of the Grantee, in their respective capacities as such, such that any recourse against Grantee, the Trustee and any such beneficiary, in their respective capacities as such, in any manner in respect of any indebtedness, obligation or liability of the Grantee arising hereunder or arising in connection herewith or from the matters to which this Agreement relates, if any, including without limitation claims based in contract, on negligence, tortious behaviour or otherwise, shall be limited to, and satisfied only out of, the Trust Properties as defined in the trust indenture establishing and governing the Grantee, amended.

This Agreement may be executed in counterpart and delivered by facsimile, and when so executed and delivered shall be deemed an original. If this Agreement is delivered by a Grantor by facsimile, the Grantor shall within a reasonable time after such delivery deliver an originally executed copy to the Grantee.

THE PARTIES have caused this Agreement to be executed effective on the day and date first above written.
