(b)        The Purchaser will, at the reasonable request of the Vendors, from time to time during the Interim Period, provide the Vendors and their representatives with copies of all applications, filings, notifications, submissions and other correspondence or documents (including drafts thereof) related to the satisfaction of the conditions to Closing together with such written advice and information with respect to the status of the Purchaser's efforts to obtain the satisfaction of the conditions to Closing as the Vendors may reasonably request.

The conditions in Section 7.1 are for the sole benefit of the Purchaser and the conditions in Section7.2 are for the sole benefit of the Vendor.  The Party for the benefit of which such conditions have been included may waive any of them, in whole or in part, by written notice to the other Party.

If any of the conditions in Sections 7.1 or 7.2 has not been satisfied at or before the Outside Date and such condition has not been waived by the Party for the benefit of which such condition has been included, such Party may terminate this Agreement pursuant to Section 8.1 by written notice to the other Party prior to the Closing.

This Agreement may be terminated prior to the Outside Date:

(a)         by the mutual written agreement of the Vendors and the Purchaser;

(b)        in accordance with Section 7.5 by the Party and in the circumstances contemplated thereby; or

(c)         by the Vendors or the Purchaser if the consummation of the transaction contemplated by this Agreement would violate any non-appealable final order, decree or judgment of any court or governmental body having competent jurisdiction;

(d)        by the Purchaser in the event that a material adverse change occurs in the PNG Assets or in assets, liabilities, or operations of the Watford Entities, Watford Energy or Amalco after the Signing Date, as the case may be;

provided that, notwithstanding anything to the contrary express or implied herein, a Party shall not be allowed to exercise any right of termination pursuant to this Section 8.1 if the event giving rise to such right is due to a Purchase Agreement Default by such Party.

If this Agreement is terminated by a Party as permitted under Section 8.1 hereof:

(a)         except as contemplated by this Section 8.2 and Section 8.3, such termination shall be without liability of any Party to any other Party to this Agreement, or to any of their shareholders, directors, officers, employees, agents, consultants or representatives, and the Parties shall be released from all of their obligations under this Agreement;

(c)         Section 8.2(b) shall not apply to termination by the Purchaser for a Purchase Agreement Default of the Vendors that arises as a result of a misrepresentation or breach of warranty made by any one or more of the Vendors under Section 5.1 which misrepresentation is beyond their reasonable control or a failure of any one or more of the Vendors to perform or observe in any material respect any of the covenants or agreements to be performed by any one or more of the Vendors which are beyond their reasonable control; and

(d)        the Purchaser shall promptly destroy or return to the Vendors all materials delivered to the Purchaser by the Vendors hereunder, together with all copies of them that may have been made by or for the Purchaser.

If this Agreement is terminated pursuant to Section 8.1  and the event giving rise to the termination is not due to the Purchase Agreement Default of the Purchaser, then the Deposit provided for in Section 2.4 shall be returned to the Purchaser, together with Deposit Interest earned thereon.  However, if the Agreement is terminated pursuant to Section 10.4 prior to Closing as a result of a Purchase Agreement Default by the Purchaser, then such Deposit, together with the Deposit Interest earned thereon, shall be retained by the Vendors and applied by the Vendors as their sole remedy on account of their damages contemplated by Section 8.2 as a genuine pre-estimate of the Vendors' minimum liquidated damages and not as a penalty.

After the Closing Date, the Vendors may upon reasonable notice to the Purchaser and subject to contractual restrictions relative to disclosure, have access during business hours to the Title and Operating Documents, any engineering report, the Financial Statements and the financial statements, books, accounts, records, minute books, Tax Returns, tax assessments, filings, maps, documents, files, information and materials of the Watford Entities, Watford Energy and Amalco delivered to the Purchaser pursuant to the terms hereof and to obtain and copy information in respect of matters arising out of or relating to any period of time through the Closing if copies of such records or if the information derived from such access would be helpful and beneficial to the Vendors:

The Vendors shall, on a timely basis,  prepare and file all Tax Returns and forms for taxes applicable to the Watford Entities, Watford Energy and Amalco for periods ending on or before the Closing Date, subject to review and approval (which approval shall not be unreasonably withheld) by the Purchaser, and the Purchaser shall provide the Vendors reasonable access to all information required to do so on a timely basis.

In this Article 10:

"Additional Indemnitees" means, with respect to any Person to which an indemnity is granted pursuant to this Article 10, its Affiliates and the respective directors, officers, servants, agents, representatives, advisors and employees of that Person and its Affiliates.

Subject to the limitations set forth herein, the Vendors shall:

(a)         be liable to the Purchaser and their Additional Indemnitees for all Indemnified Losses which any one or more of them may suffer, sustain, pay or incur; and

(b)        indemnify and save harmless the Purchaser and their Additional Indemnitees from and against all Indemnified Losses which may be brought against or suffered by any one or more of them or which any one or more of them may sustain, pay or incur;

as a direct result of any act, omission, circumstance or other matter arising out of, resulting from, attributable to or connected with any Purchase Agreement Default made by the Vendors.

Subject to the limitations set forth herein, the Purchaser shall:

(a)         be liable to the Vendors and their Additional Indemnitees for all Indemnified Losses which any one or more of them may suffer, sustain, pay or incur; and

(b)        indemnify and save harmless the Vendors and their Additional Indemnitees from and against all Indemnified Losses which may be brought against or suffered by any one or more of them or which any one or more of them may sustain, pay or incur;

as a direct result of any act, omission, circumstance or other matter arising out of, resulting from, attributable to or connected with any Purchase Agreement Default made by the Purchaser.

The Vendors' obligations and liability under this Agreement shall be subject to the following limitations:

(a)         The Vendors shall have no liability in connection with any Indemnified Losses until the aggregate of such claims exceeds Seven Hundred and Fifty Thousand ($750,000.00) Dollars and, upon the aggregate of such claims exceeding Seven Hundred and Fifty Thousand ($750,000.00) Dollars, the Vendors shall be required to indemnify in respect of only the amount of such Indemnified Losses to the extent they aggregate in excess of One Hundred and Fifty Thousand ($150,000.00) Dollars PROVIDED THAT any Indemnified Losses arising out of the Vendor's representation and warranty in Section 5.1(pp) shall not be subject to this Section 10.4(a).

(b)        Subject to Sections 10.4(c) and 10.4(d):

(c)         The obligations of the Vendors hereunder resulting from a breach by any of the Vendors in the representations and warranties contained in Sections 5.1(b), 5.1(i), 5.1(j), 5.1(k) and 5.1(l) shall be joint and several.

(d)        The obligations of the Vendors hereunder resulting from a breach by any of the Vendors of any of their respective obligations under Section 2.6(g) shall not be subject to 10.4(a).

(e)         If this Agreement is terminated prior to the Closing Date by the Purchaser pursuant to Section 8.1 the Vendors shall have no liability for Indemnified Losses arising out of, resulting from, attributable to or connected with those Purchase Agreement Defaults referred to in Section 8.2(c).

(f)         No Vendor shall have any liability in connection with Indemnified Losses unless the Purchaser shall, prior to the expiry of the Survival Period, or in the case of the representation and warranty in Section 5.4, such period indicated in Section 5.4, have provided such Party with a Notice of Claim.

Notwithstanding any provision to the contrary contained in this Article 10 references to costs in the liability and indemnification obligations prescribed by Sections 10.2 and 10.3 shall be deemed to include legal (on a solicitor-client basis) and other professional fees and disbursements on a full indemnity basis, and shall extend to settlements, satisfactions or other compromises with respect to claims by third Persons for Indemnified Losses.

Notwithstanding anything herein to the contrary:

(a)         The indemnities provided in Sections 10.2 and 10.3 shall not apply to the extent that claims for Indemnified Losses are reimbursed to the Person to be indemnified by insurance.

(b)        If Indemnified Losses suffered, sustained, paid or incurred by Persons claiming indemnity at any time before or subsequent to the making of an indemnity payment are reduced by any tax benefit or recovery, the amount of such reduction, together with Interest thereon from the date of payment thereof, shall promptly be paid by the Person claiming indemnity to the indemnifying party.

(a)         This Article 10, together with sections 2.6, 3.3, Article 7 and Article 8 sets forth the sole rights and remedies of each Party and its Additional Indemnitees in connection with (i) the transactions contemplated herein, and (ii) any act, omission, circumstance or other matter arising out of, resulting from, attributable to or connected with any Purchase Agreement Default made by the other Party, and such first mentioned Party and its Additional Indemnitees shall have no further right or remedy (whether legal, equitable, fiduciary or in tort) whatsoever, against the other Party, or its Affiliates or their respective directors, officers, servants, agents, advisors or employees.

(b)        The Purchaser acknowledges that it shall not be entitled to any rights or remedies as against the Vendors, their Affiliates or their respective directors, officers, servants, agents and employees under Applicable Law, including common law or in equity, pertaining to any Indemnified Losses, in respect of which it is required to indemnify the Vendors pursuant to Section 10.2 or 10.3, as applicable, and that it shall not be entitled to name the Vendors or their Affiliates or their respective directors, officers, servants, agents and employees under Section10.2 or 10.3, as applicable, as third party to any action pertaining or relating to any Indemnified Losses in respect of which it is required to indemnify the Vendors pursuant to Sections 10.2 or 10.3,  commenced by any third Person against the Purchaser, the Watford Entities or Watford Energy, as the case may be.

In the event that an indemnified party (the "Indemnified Party") shall become aware of any claim, proceeding or other matter (a "Claim") in respect of which the Vendors or the Purchaser (the "Indemnifying Party") agreed to indemnify the Indemnified Party pursuant to this Agreement, the Indemnified Party shall promptly give written notice thereof to the Indemnifying Party.  Such notice shall specify whether the Claim arises as a result of a claim by a person against the Indemnified Party (a "Third Party Claim") or whether the Claim does not so arise (a "Direct Claim"), and shall also specify with reasonable particularity (to the extent that the information is available) the factual basis for the Claim and the amount of the Claim, if known.

With respect to any Direct Claim, following receipt of notice from the Indemnified Party of the Claim, the Indemnifying Party shall have 60 days to make such investigation of the Claim as is considered necessary or desirable.  For the purpose of such investigation, the Indemnified Party shall make available to the Indemnifying Party the information relied upon by the Indemnified Party to substantiate the Claim, together with all such other information as the Indemnifying Party may reasonably request.  If both parties agree at or prior to the expiration of such 60 day period (or any mutually agreed upon extension thereof) to the validity and amount of such Claim, the Indemnifying Party shall immediately pay to the Indemnified Party the full agreed upon amount of the Claim, failing which the matter shall be referred to binding arbitration in such manner as the parties may agree or shall be determined by a court of competent jurisdiction.  To the extent that there are funds in the possession of the Escrow Agent, the Purchaser shall be entitled to recover amounts owing to it by the Vendors from the Escrow Amount or otherwise.

With respect to any Third Party Claim, the Indemnifying Party shall have the right, at its expense, to participate in or assume control of the negotiation, settlement or defence of the Claim and, in such event, the Indemnifying Party shall reimburse the Indemnified Party for all the Indemnified Party's out-of-pocket expenses as a result of such participation or assumption.  If the Indemnifying Party elects to assume such control, the Indemnified Party shall have the right to participate in the negotiation, settlement or defence of such Third Party Claim and to retain counsel to act on its behalf, provided that the fees and disbursements of such counsel shall be paid by the Indemnified Party unless the Indemnifying Party consents to the retention of such counsel or unless the named parties to any action or proceedings include both the Indemnifying Party and the Indemnified Party and a representation of both the Indemnifying Party and the Indemnified Party by the same counsel would be inappropriate due to the actual or potential differing interests between them (such as the availability of different defences).  If the Indemnifying Party, having elected to assume such control, thereafter fails to defend the Third Party Claim within a reasonable time, the Indemnified Party shall be bound by the results obtained by the Indemnified Party with respect to such Third Party Claim.  If any Third Party Claim is of a nature such that the Indemnified Party is required by applicable law to make a payment to any person (a "Third Party") with respect to the Third Party Claim before the completion of settlement negotiations or related legal proceedings, the Indemnified Party may make such payment and the Indemnifying Party shall, forthwith after demand by the Indemnified Party, reimburse the Indemnified Party for such payment.  If the amount of any liability of the Indemnified Party under the Third Party Claim in respect of which such payment was made, as finally determined, is less than the amount that was paid by the Indemnifying Party to the Indemnified Party, the Indemnified Party shall forthwith after receipt of the difference from the Third Party, pay the amount of such difference to the Indemnifying Party.

If the Indemnifying Party fails to assume control of the defence of any Third Party Claim, the Indemnified Party shall have the exclusive right to contest, settle or pay the amount claimed.  Whether or not the Indemnifying Party assumes control of the negotiation, settlement or defence of any Third Party Claim, the Indemnifying Party shall not settle any Third Party Claim without the written consent of the Indemnified Party, which consent shall not be unreasonably withheld or delayed.

The liabilities and indemnities created in this Article 10 shall be deemed to apply to, and shall not merge in, all assignments, transfer and other documents conveying any of the Amalco Shares to the Purchaser, notwithstanding the terms of such assignments, transfers, conveyances, novations and other documents, Applicable Law or any rule of law or equity to the contrary, and all such rules are hereby waived.

(a)         Insofar as the Parties are unable to agree on any matter which expressly may be referred to arbitration hereunder, either Party may serve the other Party written notice that it wishes such matter referred to arbitration.

(b)        The Parties shall meet within 7 days of the receipt of a notice issued pursuant to Section 11.1(a) to attempt to agree on a single arbitrator qualified by experience, education and training, to determine such matter.  If the Parties are unable to agree on the selection of the arbitrator, the Party which issued such notice shall forthwith make application to a judge of the Court of Queen's Bench of the Province of Alberta pursuant to the Arbitration Act (Alberta) for the appointment of a single arbitrator, and failing such action on the part of the Party which issued such notice, the other Party may make such application.

(a)         The arbitrator selected pursuant to Section 11.1 shall proceed as soon as is practicable to hear and determine the matter in dispute, and shall be directed to provide a written decision respecting such matter within 45 days of appointment.  The Parties shall provide such assistance and information as may be reasonably necessary to enable the arbitrator to determine such matter.

(b)        Except to the extent modified in this Article, the arbitrator shall conduct any arbitration hereunder pursuant to the provisions of the Arbitration Act (Alberta).

(c)         The liability between the Parties for the payment of the compensation and expenses of the arbitrator shall be determined by the arbitrator.

If Closing does not occur and this Agreement is terminated, then all documents, working papers and other written material obtained from the Vendors, the Watford Entities or Watford Energy in connection with this Agreement shall be returned to the Vendors, the Watford Entities or Watford Energy, as the case may be, forthwith.  No copies of such information are to be retained by the Purchaser.

The parties agree that, notwithstanding the Confidentiality Agreements, the Purchaser may issue press releases and make such filings as are necessary or desirable under the securities laws or the applicable stock exchange regulations with respect to the Closing, and the parties hereby waive any rights they may have under the Confidentiality Agreements to the extent necessary to permit such press releases and securities filings to be issued.

No waiver by any Party of any breach (whether actual or anticipated) of any of the terms, conditions, representations or warranties contained herein shall take effect or be binding upon that Party unless the waiver is expressed in writing under the authority of that Party. Any waiver so given shall extend only to the particular breach so waived and shall not limit or affect any rights with respect to any other or future breach.

This Agreement may be amended only by written instrument executed by the Vendors and the Purchaser.

Prior to Closing, no Party may assign its interest in or under this Agreement without the prior written consent of the other Parties, provided however that the Purchaser may assign its interest in or under this Agreement to an Affiliate without the prior written consent of the Vendors providing however that the Purchaser shall continue to be liable to the Vendors in the event of a Purchase Agreement Default by such assignee.

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 served properly if served in any of the following modes:

(a)         personally, by delivering the notice to the Party on which it is to be served at that Party's address for service.  Personally served 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

(b)        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 served at that Party's address for service. A notice so served shall be deemed to be received by the addressee when actually received by it, if received within normal business hours on any Business Day or at the commencement of the next ensuing Business Day following transmission if such notice is not received during business hours.

The address for service of notices hereunder of each of the Parties shall be as follows:

The Purchaser may, at its option, make an election under Section 338(g) of the U.S. Internal Revenue Code of 1986, as amended, with respect to the purchase.  If the Purchaser makes such election, it shall provide the Vendors any notice required under such Code and the regulations promulgated thereunder.

Except as specifically provided herein, all legal and other costs and expenses in connection with this Agreement and the transactions contemplated hereby shall be paid by the Party which incurred the same.  For greater certainty the Vendors shall be responsible for all costs, fees and disbursements chargeable by the Vendor's Counsel, RJBC Inc. and Waterous Securities Inc. relating directly to the transactions contemplated by or consummated as a result of this Agreement excluding (for clarification) any engineering reports prepared prior to the Closing Date.

At the Closing Date and thereafter as may be necessary, the Parties shall execute, acknowledge and deliver such instruments and take such other actions as may be reasonably necessary to fulfil their respective obligations under this Agreement.

(a)         This Agreement and all such documents executed in connection with this agreement and the transactions contemplated hereby shall be governed by, and construed and enforced in accordance with the applicable laws, other than conflict of laws rules, prevailing in the Province of Alberta.
