reasonably be expected to constitute or lead to an actual or potential Acquisition Proposal or for access to the properties or facilities, personnel, books or records of ENF or any of the Fund Group Entities by any Person that informs ENF or any of its Representatives or otherwise indicates that it is considering making, or has made, an Acquisition Proposal and any amendment thereto; and ENF shall provide to Enbridge a copy of such Acquisition Proposal and shall provide the identity of the Person making any such Acquisition Proposal together with such other details of the Acquisition Proposal or request for material information as Enbridge may reasonably request.

(d) ENF shall not accept, approve or recommend, nor enter into any agreement in respect of an Acquisition Proposal (other than a confidentiality agreement permitted by this Section 3.4), unless:

(i) the Acquisition Proposal constitutes a Superior Proposal and the Person making the Acquisition Proposal shall not have been restricted from making such Acquisition Proposal pursuant to existing confidentiality,non-disclosure or standstill agreement or similar restriction;

(ii) ENF has complied with and continues to be in compliance with its obligations in this Section 3.4;

(iii) ENF has provided Enbridge with (A) notice in writing that the Acquisition Proposal constitutes a Superior Proposal and, in connection therewith, the ENF Board has made the determinations contemplated in the definition of “Superior Proposal”, (B) copies of the proposed definitive agreement for the Superior Proposal and any confidentiality and standstill agreement between ENF and the Person making the Superior Proposal, if not previously delivered, as well as all supporting materials, including any financing documents supplied to ENF of its Representatives in connection therewith and (C) written notice regarding the value and financial terms that the ENF Board, in consultation with the ENF Financial Advisor, has determined should be ascribed to anynon-cash consideration offered under such Superior Proposal, in each case, at least four Business Daysprior to the time at which the ENF Board proposes to accept, approve, recommend or enter into any agreement relating to such Superior Proposal;

(iv) four Business Days shall have elapsed from the later of the date Enbridge received the notice, documentation and other materials referred to in Subsection 3.4(d)(iii) from ENF in respect of the Acquisition Proposal and the date on which Enbridge received notice of ENF’s proposed determination to accept, approve, recommend or to enter into any agreement relating to such Superior Proposal, and, if Enbridge has proposed to amend the terms of the transactions contemplated in this Agreement and the Arrangement in accordance with Subsection 3.4(e), the ENF Board (after receiving advice from the ENF Financial Advisor and outside legal counsel) shall have determined in good faith that the Acquisition Proposal is a Superior Proposal compared to the proposed amendment to the terms of this Agreement and the Arrangement proposed by Enbridge;

30

(v) ENF concurrently terminates this Agreement pursuant to Subsection 8.2(d)(ii);

(vi) ENF concurrently will have delivered to Enbridge written confirmation that ENF or the ENF Board has accepted, approved or recommended, or entered into such agreement relating to, the Acquisition Proposal; and

(e) During the period(s) referred to in Subsection 3.4(d)(iii) and Subsection 3.4(d)(iv), Enbridge shall have the opportunity, but not the obligation, to propose to amend the terms of the transactions contemplated in this Agreement and the Arrangement and ENF shall, and shall cause its counsel and other advisors to,co-operate with Enbridge with respect thereto, including negotiating with Enbridge and their counsel and other advisors to enable Enbridge to propose such adjustments to the terms and conditions of this Agreement and the Arrangement as Enbridge deems appropriate and as would enable ENF to proceed with the Arrangement and the transactions contemplated in this Agreement on such adjusted terms. The ENF Board shall review any proposal by Enbridge to amend the terms of the transactions contemplated in this Agreement and the Arrangement in order to determine, in good faith in the exercise of its fiduciary duties, whether Enbridge’s proposal to amend the transactions contemplated by this Agreement and the Arrangement would result in the Acquisition Proposal not being a Superior Proposal compared to the proposed amendment to the transactions contemplated by this Agreement and the Arrangement. In the event that Enbridge proposes to amend the terms of the transactions contemplated in this Agreement and the Arrangement such that the Acquisition Proposal would not result in a transaction more favourable to the ENF Shareholders, from a financial point of view, than the Arrangement as so amended, as determined by the ENF Board in good faith (after receiving advice from the ENF Financial Advisor and outside legal counsel) and Enbridge advises the ENF Board of such proposed amendment within four Business Days of receiving notice of such Superior Proposal, the ENF Board shall not: (i) accept, recommend, approve or enter into any agreement to implement such Superior Proposal; or (ii) withdraw, modify or change its recommendation in respect of the Arrangement. For greater certainty, each successive amendment to an Acquisition Proposal shall constitute a new Acquisition Proposal for the purposes of this Section 3.4 and shall initiate a new four Business Day match right period.

(f) Enbridge agrees that all information that may be provided to it by ENF with respect to any Superior Proposal pursuant to this Section 3.4 shall be treated as if it were “Confidential Information” as that term is defined in the Confidentiality Agreement and shall not be disclosed or used except in accordance with the provisions of the Confidentiality Agreement or in order to enforce its rights under this Agreement in legal proceedings.

31

(g) If required by Enbridge, ENF shall reaffirm its recommendation of the approval of the Arrangement by press release promptly in the event that:

(i) any Acquisition Proposal is publicly announced unless such Acquisition Proposal constitutes a Superior Proposal and ENF otherwise complies with Subsections 3.4(d) and (e) in respect thereof; or

(ii) the Parties have entered into an amended agreement pursuant to Subsection 3.4(e) which results in any Acquisition Proposal not being a Superior Proposal.

Enbridge and its counsel shall be given a reasonable opportunity to review and comment on the form and content of any such press release. Such press release shall state that the ENF Board has determined that the Acquisition Proposal is not a Superior Proposal and shall reaffirm the approvals, determinations and recommendations of the ENF Board in respect of this Agreement and the Arrangement.

(h) In the event that ENF provides the notice contemplated by Subsection 3.4(d)(iii) on a date which is less than four Business Days prior to the ENF Meeting, Enbridge shall be entitled to require ENF to adjourn or postpone the ENF Meeting to a date that is not more than seven Business Days following the date after ENF has complied with its obligations under Subsections 3.4(b)(vi)(B) and (C).

(i) Neither ENF nor the ENF Board shall withdraw, or qualify, amend or modify in a manner adverse to Enbridge, the approval or recommendation of the Arrangement by the ENF Board, except if such withdrawal, qualification, amendment or modification occurs simultaneously with the entry by ENF, in accordance with the requirements of Subsection 3.4(d) and Subsection 3.4(e), into a definitive agreement with respect to an Acquisition Proposal constituting a Superior Proposal.

(j) Nothing contained in this Agreement shall prevent the ENF Board from complying with Division 3 of National Instrument 62-104,Takeover Bids and Issuer Bids and similar provisions under Applicable Laws relating to the provision of directors’ circulars and making appropriate disclosure to its securityholders.

(k) ENF shall ensure that its Representatives are aware of the provisions of this Section 3.4, and any violation of or the taking of any action which is inconsistent with any of the restrictions set forth in this Section 3.4 by any Representative shall be deemed to constitute a breach of this Section 3.4 by its Representatives.

3.5 Access to Information

(a) From and after the date hereof until the earlier of the Effective Time or the termination of this Agreement, ENF shall, subject to compliance with Applicable Laws and the terms of any contracts, upon reasonable prior notice, provide Enbridge and its representatives access, during normal business hours, to its premises, books, contracts, records, computer systems, properties, employees and management personnel and will use its reasonable commercial efforts to furnish to Enbridge such information concerning its business, properties and personnel as Enbridge may reasonably request in order to permit Enbridge to be in a position to expeditiously and efficiently integrate ENF’s business and operations immediately upon, but not prior to, the Effective Date. ENF agrees to use reasonable commercial efforts to keep Enbridge fully apprised in a timely manner of every circumstance, action, occurrence or event occurring or arising after the date hereof that would be relevant and material to a prudent operator of the business and operations of ENF including, but not limited to, promptly providing Enbridge with any and all monthly activity reports.

32

(b) ENF agrees to:

(i) give the legal and professional representatives and agents of Enbridge reasonable access during normal business hours to ENF’s books, records and documents as Enbridge may reasonably request, provided that ENF is satisfied, acting reasonably, that the confidentiality of the subject matter of the disclosure can be maintained in accordance herewith; and

(ii) endeavour to include in the information furnished to Enbridge information which would reasonably be considered to be relevant for the purposes of Enbridge’s investigation and not knowingly withhold any information which would make anything contained in the information delivered erroneous or misleading.

(c) The Parties acknowledge and agree that all information provided by ENF to Enbridge or by Enbridge to ENF pursuant to this Section 3.5 shall remain subject to the provisions of the Confidentiality Agreement.

(d) Nothing in the foregoing shall require ENF to disclose information which it is prohibited from disclosing pursuant to a written confidentiality agreement or confidentiality provision of an agreement with a third party or information which, in the opinion of ENF, acting reasonably, is competitively sensitive (provided that Enbridge acknowledges and agrees that Enbridge’s external counsel may have access to such information on a privileged and confidential basis in connection with obtaining the Competition Act Approval).

5.5 Satisfaction of Conditions

The conditions set out in this Article 5 are conclusively deemed to have been satisfied, waived or released when, with the agreement of the Parties, Articles of Arrangement are filed under the ABCA to give effect to the Arrangement.

ARTICLE 6

AGREEMENT AS TO DAMAGES

6.1 Enbridge Damages

If at any time after the execution of this Agreement this Agreement is terminated:

(a) by Enbridge pursuant to Subsection 8.2(c)(i), 8.2(c)(ii) or 8.2(c)(iii);

(b) by ENF or Enbridge pursuant to Subsection 8.2(b)(i) or Subsection 8.2(b)(ii), but prior to such termination an Acquisition Proposal shall have been announced, made or otherwise publicly disclosed (and not withdrawn) prior to the date proposed for the ENF Meeting and the ENF Shareholders do not approve the Arrangement or the Arrangement is not submitted for their approval, and thereafter ENF shall have entered into or become party to a contract with respect to any Acquisition Proposal (whether or not such Acquisition Proposal is the same Acquisition Proposal referred to above) within nine months of the date of such termination by ENF or Enbridge; or

(c) by ENF pursuant to Subsection 8.2(d)(ii),

(each of the above being an “Enbridge Damages Event”), ENF shall pay to Enbridge$165,000,000(the “Enbridge Damages Fee”) as liquidated damages in immediately available funds to an account designated by Enbridge, with the Enbridge Damages Fee to be paid (i) in the case of Subsection 6.1(a), within two Business Days of termination, (ii) in the case of

45

Subsection 6.1(b), on the date on which the Acquisition Proposal (as it may be modified or amended) is consummated (whether occurring during such nine month period or thereafter, and (iii) in the case of Subsection 6.1(c), in accordance with Subsection 3.4(d). Following an Enbridge Damages Event, but prior to payment of the Enbridge Damages Fee as required, ENF shall be deemed to hold such funds in trust for Enbridge. ENF shall only be obligated to pay the Enbridge Damages Fee once pursuant to this Section 6.1. For the purposes of the foregoing, the term “Acquisition Proposal” shall have the meaning assigned to such term in Section 1.1, except that references to “20% or more” shall be deemed to be references to “50% or more”.

6.2 ENF Damages

If, at any time after the execution of this Agreement but prior to the termination of this Agreement, ENF shall have terminated this Agreement pursuant to Subsection 8.2(d)(i) (the “ENF Damages Event”), Enbridge shall pay to ENF $165,000,000(the “ENF Damages Fee”) as liquidated damages in immediately available funds to an account designated by ENF within two Business Days of such termination. Following an ENF Damages Event, but prior to payment of the ENF Damages Fee as required, Enbridge shall be deemed to hold such funds in trust for ENF. Enbridge shall only be obligated to pay the ENF Damages Fee once pursuant to this Section 6.2.

6.3 Injunctive Relief and Remedies

Each Party agrees that irreparable harm would occur for which money damages would not be an adequate remedy at law in the event that any of the provisions of this Agreement were not performed by the other Party in accordance with their specific terms or were otherwise breached. It is accordingly agreed that each Party shall be entitled to seek injunctive relief to restrain any breach or threatened breach by the other Party of the covenants or agreements set forth in this Agreement or otherwise to obtain specific performance of any of such act, covenants or agreements, without the necessity of posting bond or security in connection therewith, this being in addition to any other remedy to which such Party may be entitled at law or in equity. Each of the Parties acknowledges that the agreements contained in Sections 6.1 and 6.2 are an integral part of the transaction contemplated by this Agreement, and that without these agreements the Parties would not enter into this Agreement; and further that the payment of the Enbridge Damages Fee in the circumstances set out in Section 6.1 and the payment of the ENF Damages Fee in the circumstances set out in Section 6.2 is a payment of liquidated damages which is a genuinepre-estimate of the damages which Enbridge or ENF, as applicable, shall suffer or incur as a result of the event giving rise to such damages and resultant termination of this Agreement and is not a penalty. ENF and Enbridge, as applicable, irrevocably waives any right it may have to raise as a defence that any such liquidated damages are excessive or punitive. For greater certainty, ENF agrees that its right to receive the ENF Damages Fee and Enbridge agrees that its right to receive the Enbridge Damages Fee, each in the manner provided in this Article 6, is such Party’s sole and exclusive remedy against the other Party in respect of the event(s) giving rise to such payment, as applicable; provided that, this limitation shall not apply to a Party in the event of fraud or willful breach of this Agreement by the other Party.

46

ARTICLE 7

AMENDMENT

7.1 Amendment

This Agreement may, at any time and from time to time, before or after the holding of the ENF Meeting but not later than the Effective Time, be amended by written agreement of the Parties, subject to the Interim Order, the Final Order and Applicable Laws, without further notice to or authorization on the part of the ENF Shareholders, provided that no such amendment reduces or adversely affects the consideration to be received by an ENF Shareholder without approval by the ENF Shareholders given in the same manner as required for the approval of the Arrangement or as may be ordered by the Court.

7.2 Waiver

No waiver of any of the provisions of this Agreement will constitute a waiver of any other provision (whether or not similar). No waiver will be binding unless executed in writing by the Party to be bound by the waiver. A Party’s failure or delay in exercising any right under this Agreement will not operate as a waiver of that right. A single or partial exercise of any right will not preclude a Party from any other or further exercise of that right or the exercise of any other right.

Enbridge will not be responsible for the proper completion of any election form and, except for Enbridge’s obligation to return (within 60 days after the receipt thereof by the Depositary) duly completed election forms which are received by the Depositary within 90 days of the Effective Date, Enbridge will not be responsible for any taxes, interest or penalties resulting from the failure by an ENF Electing Shareholder to properly complete or file the election forms in the form and manner and within the time prescribed by the Tax Act (or any applicable provincial legislation). In its sole discretion, Enbridge may choose to sign and return an election form received by the Depositary more than 90 days following the Effective Date, but Enbridge will have no obligation to do so.

A-8

and, notwithstanding the provisions of section 191 of the ABCA, in no event shall Enbridge, ENF or any other Person be required to recognize: (i) any Person who exercises Dissent Rights unless such Person is the registered holder of those ENF Shares in respect of which such rights are sought to be exercised; or (ii) Dissenting Shareholders as holders of ENF Shares in respect of which Dissent Rights have been validly exercised after the completion of the transfer under Subsection 2.2(b), and the names of such Dissenting Shareholders shall be removed from the registers of holders of the ENF Shares in respect of which Dissent Rights have been validly exercised at the same time as the event described in Subsection 2.2(b) occurs.

In addition, a Dissenting Shareholder may only exercise Dissent Rights in respect of all, and not less than all, of its ENF Shares or on behalf of any one beneficial owner and registered in the name of the Dissenting Shareholder.

3.4    Notwithstanding subsection 191(5) of the ABCA, the written objection to the Arrangement Resolution referred to in subsection 191(5) of the ABCA must be received in accordance with the Interim Order by ENF no later than 4:00 p.m. (Calgary time) on the second Business Day immediately preceding the day of the ENF Meeting.

4.7 Termination of Rights

Subject to Applicable Laws relating to unclaimed property, any certificate formerly representing ENF Shares that is not deposited with all other documents as required by this Plan of Arrangement, or any payment made by way of cheque to the Depositary pursuant to this Plan of Arrangement that has been returned to the Depositary or that otherwise remains unclaimed on or before the day prior to the third anniversary of the Effective Date shall cease to represent a right or interest of or a claim by any former ENF Shareholder of any kind or nature against Enbridge. On such date, the Enbridge Shares and Cash Consideration to which the former holder of the certificate referred to in the preceding sentence was ultimately entitled, or the claim to payment hereunder that remains outstanding, as the case may be, shall be deemed to have been surrendered and forfeited to Enbridge, together with all entitlements to dividends or distributions thereon held for such former registered holder, for no consideration, and such shares and rights shall thereupon terminate and be cancelled and the name of the former registered holder shall be removed from the register of holders of such shares.

WITHHOLDINGS

Enbridge, ENF and the Depositary shall be entitled to deduct and withhold from any consideration otherwise payable to any former ENF Shareholder under this Plan of Arrangement, including from any amount payable to any Dissenting Shareholder or any dividend or other distribution payable pursuant to Section 4.6, as the case may be, such amounts as Enbridge, ENF or the Depositary is required to deduct and withhold from such consideration in accordance with the Tax Act, the United States Internal Revenue Code of 1986, or any other provision of any Applicable Laws. Any such amounts will be deducted and withheld from the consideration payable pursuant to this Plan of Arrangement and shall be treated for all purposes as having been paid to the former ENF Shareholder in respect of which such deduction and withholding was made, provided that such withheld amounts are actually remitted to the appropriate taxing authority. To the extent that the amount so required to be deducted or withheld from any payment to a former ENF Shareholder exceeds the cash component, if any, of the consideration otherwise payable to the holder, Enbridge and the Depositary are hereby authorized to sell or otherwise dispose of such portion of the Enbridge Shares otherwise issuable to the holder as is necessary to provide sufficient funds to Enbridge or the Depositary, as the case may be, to enable it to comply with such deduction or withholding requirement and Enbridge or the Depositary shall notify the holder thereof and remit the applicable portion of the net proceeds of such sale to the appropriate taxing authority and shall remit to such holder any unapplied balance of the proceeds of such sale.
