3.1 Relationship between the Parties

3.1.1 Subject to the terms and conditions hereof, APUC and Emera shall use their commercially reasonable efforts to jointly pursue Qualified Opportunities for investment, including sharing market intelligence and business development leads.

(a) To the extent Emera becomes aware of a Potential Opportunity in the Areas of APUC Pursuit, Emera shall bring the Potential Opportunity to the attention of the APUC by way of a Joint Pursuit Notice.

(b) To the extent APUC becomes aware of an opportunity in the Areas of Emera Pursuit, APUC shall bring such opportunity to the attention of the Emera by way of a written notice to Emera generally describing such opportunity.

3.1.2 Except as expressly provided in Section 3.1.3 or 3.1.4, the Parties shall pursue investment opportunities in accordance with the following principles and understandings:

(b) APUC shall not invest in, or directly or indirectly own or invest in any Person (other than a joint venture or partnership with Emera or any of its Subsidiaries) engaged in, the Areas of Emera Pursuit.

(c) To the extent a Qualified Opportunity related to a Non-Rate Base Power Project exceeds a total enterprise value of $500 million and the investment requirement in respect of such Qualified Opportunity is determined by the Board of Directors to be unacceptably large for APUC, the investment into such Non-Rate Base Power Project (being an “Other Non-Rate Base Power Project”) may, as the Parties may mutually agree, be restructured such that:

(i) the Development Project portion of such Qualified Opportunity shall be pursued by APUC; and

(e) a Party or any of its Affiliates (a “Permitted Party”) from acquiring any business or Person as an integral part of a larger transaction or acquisition of a business, Person or group of Persons, or the entering into of a joint venture or any other arrangement with one or more other Persons, to the extent that the acquired business or Person or arrangement does not predominantly engage in (i) if the Permitted Party is Emera or any of its Affiliates, Areas of APUC Pursuit, and (ii) if the Permitted Party is APUC or any of its Affiliates, Areas of Emera Pursuit; and

(f) for greater certainty, (i) Emera shall not acquire Common Shares or Convertible Securities such that the Emera Holdings exceed the 25% Threshold; (ii) if Emera Holdings equal or exceed the 25% Threshold, this Agreement will remain in effect in all respects (and the ROFR, subject to the terms set out in Section 4.1, will continue to apply to Issuances thereafter), (iii) if, after Emera Holdings equal or exceed the 25% Threshold, additional Common Shares are issued thereafter such that the Emera Holdings are less than the 25% Threshold, Emera shall be permitted to acquire, through open market purchases, Common Shares and/or Convertible Securities from time to time, in amounts such that Emera Holdings may equal the 25% Threshold.

3.2 Determination of Qualified Opportunities

3.2.1 In this Agreement:

(b) “Qualified Opportunity” means a Potential Opportunity which is determined by the Board of Directors to be a Qualified Opportunity. Without in any way fettering the discretion of the Board of Directors, it is anticipated that a Potential Opportunity in respect of which the business intelligence, participation and support of Emera will meaningfully improve the possibility of successful exploitation would be determined to be a Qualified Opportunity.

3.2.2 Prior to delivery of a Joint Pursuit Notice, Emera and APUC shall discuss potential opportunities which may qualify as Potential Opportunities to determine their suitability to the Parties. Following receipt of a Joint Pursuit Notice, the Board of Directors shall determine whether the Potential Opportunity referenced therein is a Qualified Opportunity or a Non-Qualified Opportunity. APUC shall provide written notice (a “Notice of Determination”) to Emera promptly following the meeting of the Board of Directors at which such Joint Pursuit Notice is discussed, as to the Board of Director’s determination in respect of such Potential Opportunity detailed in the Joint Pursuit Notice. If APUC fails to provide such notice within forty-five (45) days (the “Determination Period”) of Emera giving to APUC a Joint Pursuit Notice in respect of such Potential Opportunity, such Potential Opportunity shall be deemed to be a Non-Qualified

- 10 -

Opportunity. During the Determination Period, APUC will not, directly or indirectly, disclose to, or discuss with, any Person (other than advisors to and the directors, officers and employees of APUC or its Subsidiaries who have a need to know such information for purposes of enabling the Board of Directors to determine whether such Potential Opportunity is a Qualified Opportunity or Non-Qualified Opportunity) any confidential information provided by Emera to APUC regarding the applicable Potential Opportunity.

3.2.3 If the Board of Directors determines that the Potential Opportunity is a Qualified Opportunity, Emera’s rights under Article 4 shall apply.

3.3 Cooperation Opportunities in Areas of Emera Pursuit

If APUC wishes to pursue a business opportunity within the Emera Areas of Pursuit, it shall communicate its interest in such opportunity to Emera and Emera and Algonquin shall consult with each other to determine whether there is any mutually amenable method of cooperating with respect to such opportunity.

3.4 Construction and Energy Trading Services

(a) APUC and its Affiliates will not develop, own, manage, operate or control any utility construction or wholesale energy trading, energy management or gas transportation or storage services businesses that compete with services currently provided by Emera Energy Services Inc. and/or Emera Utility Services Inc.; provided that APUC’s Affiliate which carries on an energy trading business shall be permitted to continue to carry on such business as currently conducted and APUC shall be permitted to own and operate a wholesale energy trading business which predominantly serves the internal energy trading, energy management or gas transportation or storage service requirements of the assets of APUC and its Affiliates, whether now owned or subsequently acquired (b) in respect of any Qualified Opportunity, it is agreed that to the extent that APUC elects to procure utility construction services, energy trading services, energy management services or gas transportation or storage services which Emera Energy Services Inc. or Emera Utility Services Inc. is qualified to provide, APUC shall, to the extent reasonably practicable, discuss the requirements with Emera’s Affiliate and offer such affiliate an opportunity to make a proposal to fulfill APUC’s requirements for such services and APUC agrees to give such proposal due consideration.

ARTICLE 4

RIGHT OF FIRST REFUSAL

4.1 Right of First Refusal

From time to time, as APUC pursues Qualified Opportunities developed in conjunction with Emera pursuant to Article 3, and in respect of which APUC wishes to issue (an “Issuance”) additional Common Shares or Convertible Securities, subject to any approvals required under Applicable Securities Laws (including TSX approval, if required):

(a) if the Emera Holdings are less than the 25% Threshold, Emera shall have a right of first refusal (i.e. pre-emptive right) to subscribe for up to 100% of such new securities issued, in an amount to bring Emera Holdings up to the 25% Threshold; and

(b) Emera shall have a right of first refusal to subscribe for up to 25% of the balance of such new securities issued,

- 11 -

subject at all times to Emera Holdings being less than or equal to the 25% Threshold.

For greater certainty, (i) if an Issuance which the Board of Directors determines is anticipated to be in whole or in part related to one or more Qualified Opportunities occurs before the acquisition or development of one or more Qualified Opportunities, the ROFR shall apply to the portion of such Issuance which the Board of Directors determines is anticipated to be related to one or more Qualified Opportunities; and (ii) if an Issuance relates in part to one or more Qualified Opportunities and in part to Non-Qualified Opportunities or other purposes, the Board of Directors shall determine the portion of such Issuance which relates to one or more Qualified Opportunities and the ROFR shall apply to such portion of the Issuance.

If APUC elects not to effect an Issuance in connection with a Qualified Opportunity or elects to fund a Qualified Opportunity in whole or in part by debt then, APUC shall provide written notice (an “Election Notice”) to Emera of such election and Emera shall be entitled, but not obligated, to purchase Common Shares in the public market at any time prior to 90 days after APUC makes its investment in such Qualified Opportunity in an aggregate number of shares equal to or less than the lesser of (i) the amount which would result in its holdings being equal to the 25% Threshold; or (ii) a number of shares equal to fifty percent (50%) of the aggregate investment made by APUC in such Qualified Opportunity divided by the average closing price of the Common Shares for the 20 days preceding the investment in such Qualified Opportunity.

Emera shall also have the right to purchase additional Common Shares from time to time through the public markets, provided that the percentage ownership of Common Shares held by Emera and its Affiliates after completion of such purchases, being the number expressed as a percentage by multiplying (A) the quotient obtained by dividing (i) the Emera Holdings after completion of such purchases by (ii) the number of Common Shares issued and outstanding at that time, by (B) 100 does not exceed the highest percentage ownership of Common Shares held by Emera and its Affiliates in compliance with this Agreement (and subject always to the 25% Threshold) prior to such date and calculated in the manner set forth above.

4.2 Terms and Conditions

At any time when APUC is contemplating an Issuance which would be subject to the ROFR, APUC shall provide written notice of such Issuance to Emera and Emera shall have ten (10) Business Days thereafter in which to advise APUC in writing whether or not it wishes to exercise its ROFR in whole or in part. If the exercise of the ROFR requires any regulatory approval, APUC shall use its reasonable efforts to obtain such approval in a timely manner and

- 12 -

Emera agrees to use its reasonable efforts to cooperate and assist APUC in obtaining such approval. Any subscription by Emera for Common Shares or Convertible Securities under its ROFR shall be on the same terms and conditions as APUC proposes to offer to third party purchasers of such securities. Without limiting the foregoing, any such subscription shall be completed pursuant to a subscription agreement setting out such representations, warranties and covenants as are customary in private placements of the securities of a reporting issuer in Canada, Any purchase of Common Shares or Convertible Securities pursuant to Section 4.1 shall be subject to applicable Securities Laws, including any requirements of the TSX, and Emera agrees to comply with Applicable Securities Laws in exercising its rights under Section 4.1.

4.3 Shareholder Approval

APUC shall, at its next annual meeting of Shareholders, request that Shareholders pass resolutions approving (a) any issuance pursuant to this Agreement of Common Shares or Convertible Securities which would cause the total holdings by Emera of Common Shares on a fully diluted basis to exceed 19.99% of the total Common Shares outstanding on a fully diluted basis, subject to the 25% Threshold, (b) any issuance of Calpeco Transaction Shares, and (c) the waiver of the applicable provisions of the Shareholder Rights Plan in respect of the issuance of securities approved under the resolution described in clause (a) or clause (b) above.
