Sale”) to any Third Party (a “Tag Along Purchaser”), then Pattern shall be required to provide PSP with at least thirty (30) days’ prior written notice (the “Tag Along Notice”) of such proposed Tag Along Sale.

Neither Pattern nor any Affiliate thereof shall have entered into any collateral agreement, commitment or understanding with the Tag Along Purchaser or its affiliates that has or would have the effect of providing to Pattern or any such Affiliate consideration of greater value than the consideration offered pursuant to the Tag Along Sale; provided that such restriction shall not apply to any commercial agreement in effect at the time of such transaction (including, for the avoidance of doubt, the O&M Contract) that was entered into following receipt of any approvals, if any, required by PSP pursuant to Section 3.3 of the Shareholders Agreement. If the Tag Along Purchaser does not accept all of the Tagging Interests tendered by PSP, then Pattern shall have the option to either (a) proportionately reduce the number of Tag Sale Interests and Tagging Interests to account for the maximum number of ownership interests that the Tag Along Purchaser is willing to purchase or (b) abandon the Tag Along Sale. If PSP does not deliver a Tag Along Acceptance Notice within twenty (20) days after receipt of the Tag Along Notice, PSP shall be deemed to have waived its rights with respect to the Transfer of its Units pursuant to the applicable Tag Along Sale and Pattern shall have until one hundred eighty (180) days after the expiration of such twenty (20) day period after the date of the Tag Along Notice in which to Transfer the ownership interests described in the Tag Along Notice on terms not materially more favorable (in the aggregate) to Pattern than those set forth in the Tag Along Notice. If at the end of such one hundred eighty (180) day period Pattern shall not have completed the Transfer of all of Pattern’s ownership interests contemplated to be Transferred in the Tag Along Notice (reduced to account for any and all Tagging Interests (if any)), then PSP’s tag along rights shall again apply with respect to any such unsold ownership interests.

In addition, PSP may not Transfer any Units, at any time, to a Competitor. In addition, no Limited Partner may Transfer any Units (other than to a Controlled Affiliate) unless such Limited Partner or its Affiliate holding shares in the capital of the General Partner also Transfers all or part of such shares to the Transferee (or its Affiliate) in accordance with Article 6 of the Shareholder Agreement.

security interest in any of its Units as General Partner in connection with any Project Financing being provided to the Project Partnership. Transfers of such Units to a secured party or any subsequent transferee in connection with any such financing are permitted.

Notwithstanding anything to the contrary herein of the Agreement, any Limited Partner (including any substituted or additional limited partners of the Partnership from time to time) may pledge or otherwise grant a security interest in any of its Units as Limited Partner in connection with any Project Financing being provided to the Project Partnership. Transfers of such Units to a secured party or any subsequent transferee in connection with any such financing are permitted.

None of the rights of first offer, “drag-along” or “tag-along” rights contained in this Article 7 shall be triggered by (a) a Transfer pursuant to a pledge to a Third Party lender as required pursuant to the terms of any Project Financing (b) a Transfer by such Third Party lender pursuant to a realization of such security, or (c) a Transfer of Units in accordance with Section 7.7.

If any Limited Partner defaults in transferring Units pursuant to a Transfer that is required pursuant to Article 7, and except as otherwise provided in Section 7.7, the General Partner is authorized and directed to receive the purchase money therefor from the buyer and thereupon to record the transfer of Units, to enter the name of the buyer in the registers of the Partnership as the holder of the Units purchased by the buyer from the seller, and cause to be issued to the buyer Unit Certificates for such Units in the name of the buyer. The General Partner will hold the purchase money received by it in trust on behalf of the seller and will not commingle the purchase money with the General Partner’s or the Partnership’s assets, except that any interest accruing thereon will be for the account of the Partnership. The receipt by the General Partner of the purchase money will be a good discharge to the buyer and, after the name of the buyer has been entered in the registers of the Partnership as the holder of the Units purchased by it, the purchase and sale will be deemed completed at the price and on the terms and conditions contemplated herein and the buyer will for all purposes own the Units purchased by it. Upon such registration, the seller will cease to have any right to or in respect of the Units except the right to receive, without interest, the purchase money received by the General Partner upon surrender of any certificates that previously represented such Units.

such Person as if such Partner had itself committed such breach. “Confidential Information” shall not include: (1) public information or information in the public domain at the time of its receipt by PSP or its Representatives; (2) information which becomes public through no fault or act of PSP or its Representatives; or (3) information received by PSP or its Affiliates in good faith from a third party lawfully in possession of the information and not in breach of any confidentiality obligations. PSP acknowledges that it is aware that (i) Confidential Information and Competitively Sensitive Information (as defined below) contains material, non-public information regarding the Partnership, the Project Partnership, their respective Affiliates and PEGI and (ii) United States and Canadian securities laws prohibit any persons who have material, non-public information from purchasing or selling securities of a company using such information or from communicating such information to any Person (including its Affiliates) under circumstances in which it is reasonably foreseeable that such Person is likely to purchase or sell such securities in reliance upon such information. PSP further confirms that it has in place internal information protection mechanisms to prevent unauthorized use of the Confidential Information and Competitively Sensitive Information.

Each Limited Partner shall, and shall cause its Affiliates, to consult with the other Limited Partner and provide that other Limited Partner a reasonable opportunity to comment before issuing

any press release or making any other public announcement regarding the other Limited Partner, provided that (i) in the case of any disclosure required by Applicable Law or stock exchange rule, such consultation and opportunity to comment shall only be required to the extent reasonably practicable under the circumstances and (ii) no consultation and opportunity to comment shall be required with respect to any disclosure that is substantially similar to prior public disclosure made in compliance with the terms of this Agreement.

The provisions of this Article 12 will enure to the benefit of the Partnership, the Project Partnership and their respective Subsidiaries, if any, notwithstanding that the Project Partnership and the foregoing Subsidiaries are not parties hereto.

The provisions of this Article 12 will survive the termination of this Agreement or dissolution of the Partnership.

The Partnership will continue until the Partnership is dissolved pursuant to Section 13.2 or by operation of law, and the property of the Partnership has been distributed as provided for herein.

The Partnership shall continue from the date hereof until it is dissolved upon the first to occur of the following:

Subject where applicable to compliance with the provisions of the Act for the renewal thereof, the Partnership shall not dissolve or terminate upon the death, bankruptcy, assignment of property in trust for the benefit of creditors or withdrawal of or attempted withdrawal by any Limited Partner, or the admission of any additional or substituted limited partners.

Each Partner will look solely to the property of the Partnership for all distributions and will have no recourse therefor, upon dissolution or otherwise, against the property of any other Partner. Notwithstanding the dissolution of the Partnership, the business of the Partnership and the affairs of the Partners, as such, will continue to be governed by this Agreement until termination of the Partnership, as provided for in this Agreement. Upon dissolution of the Partnership, the General Partner, or, if there is no General Partner, a liquidator (who may be a Partner) appointed by the written approval of all of the Limited Partners, will liquidate the property of the Partnership and apply and distribute the proceeds thereof as contemplated by this Agreement.

such unapplied reserves shall be distributed to the Partners in accordance with their Unit Interests immediately prior to the dissolution of the Partnership.

The General Partner hereby represents and warrants as follows, and acknowledges and confirms that the other Partners are relying on such representations and warranties in entering into this Agreement:

Each Limited Partner hereby represents and warrants as follows, and acknowledges and confirms that the other Partners are relying on such representations and warranties in entering into this Agreement:

contracts or instruments to which the Limited Partner is a party or pursuant to which any of the Limited Partner’s assets may be affected; and

The representations, warranties and covenants of the Partners contained in this Article 14 survive the execution and delivery of this Agreement and continue in full force and effect with respect to each Partner until it ceases to be bound by the provisions of this Agreement.

If any provision of this Agreement has the effect of imposing upon any Limited Partner any of the liabilities or obligations of a general partner under the Act, such provision will be deemed to be of no force and effect and severed from the remainder of this Agreement.

Each Person who becomes a Limited Partner must concurrently with becoming a Limited Partner execute and deliver to the Partnership a counterpart copy of this Agreement or a written agreement in form and substance satisfactory to the Parties, agreeing to be bound by this Agreement, including making the representations and warranties contained in Article 14.

This Agreement, together with the Shareholder Agreement, constitute the entire agreement between the Parties with respect to the subject matter hereof and supersede all prior agreements, understandings, negotiations and discussions, whether oral or written (including the Original Limited Partnership Agreement). There are no conditions, representations, warranties or other agreements between the Parties with respect to the subject matter hereof, whether oral or written, express or implied, statutory or otherwise, except as specifically set out in this Agreement and the Shareholder Agreement. Any actions taken by the General Partner in its own capacity or the General Partner in its capacity as the general partner of the Partnership, including the entering into or the amendment, waiver or termination of any Related Party Contract pursuant to Section 4.3, shall be subject to the applicable provisions of the Shareholder Agreement, and any action taken by the General Partner in violation of any provision of the Shareholder Agreement shall be null and void ab initio.

Notwithstanding anything in this Agreement to the contrary, the Partnership and the General Partner shall have the right to set off against any amount that would otherwise have been paid to a Limited Partner hereunder, any amount owing by the Limited Partner to the Partnership, including any amount owing as a result of a breach by the Limited Partner of its obligations hereunder.

A waiver of any default, breach or non-compliance under this Agreement is not effective unless it is in writing and signed by the Party to be bound by the waiver. No waiver will be inferred from or implied by any failure to act or delay in acting by a Party in respect of any default, breach or non-compliance or by anything done or omitted to be done by that Party. The waiver by a Party of any default, breach or non-compliance under this Agreement will not operate as a waiver of that Party’s rights under this Agreement in respect of any continuing or subsequent default, breach or non-compliance, whether of the same or any other nature.

This Agreement will be construed in accordance with the laws of the Province of Ontario and the federal laws of Canada applicable therein (without reference to conflicts of law principles). Each of the Parties irrevocably attorns to the jurisdiction of the courts of the Province of Ontario but nothing in this Agreement will preclude any Party from bringing suit or taking other legal action in any other jurisdiction.

Any provision of this Agreement that is prohibited or unenforceable in any jurisdiction will, as to that jurisdiction, be ineffective to the extent of such prohibition or unenforceability and will be severed from the balance of this Agreement, all without affecting the remaining provisions of this Agreement or affecting the validity or enforceability of such provision in any other jurisdiction.

Time will be of the essence of this Agreement in all respects.

Each Party will promptly do, execute and deliver or cause to be done, executed and delivered all further acts, documents and things in connection with this Agreement that any other Party may reasonably require for the purpose of giving effect to this Agreement.

This Agreement will enure to the benefit of and be binding on the Parties and their respective heirs, executors, administrators, successors and permitted assigns.

Except as otherwise provided for in Section 12.1(7) of this Agreement, if any dispute, claim, question or differences arises out of or in relation to this Agreement, or any breach hereof, (a “Dispute”) the Parties to this Agreement shall each use commercially reasonable efforts to settle the Dispute prior to resorting to commencing a proceeding in respect of such Dispute ( “Initial Good Faith Discussions”). Notwithstanding the foregoing, if the Dispute is not resolved within ten (10) days of commencing such Initial Good Faith Discussions, the Parties shall refer such Dispute to their respective senior representatives, who shall in turn use commercially reasonable efforts to settle the Dispute (the “Escalated Good Faith Discussions”). If such Dispute remains unresolved following the date that is ten (10) days following the commencement of the Escalated Good Faith Discussions, any Party may, following delivery of written notice to the other Party or Parties, as applicable, commence an action in respect of such Dispute.

No Party may assign or transfer, whether absolutely, by way of security or otherwise, all or any part of its rights or obligations under this Agreement unless approved by the General Partner and the Limited Partners, except where such assignment or transfer is being made together with the Transfer of its Units in accordance with this Agreement.

All certificates representing Units will have a legend endorsed on them substantially as follows:

“There are restrictions on the right to transfer the Units represented by this certificate. In addition, such Units are subject to an Amended and Restated Limited Partnership Agreement dated as of August 2, 2019 between Pattern Canada Finance Company ULC, Vertuous Energy Trust and Pattern Belle River GP Holdings Inc., as amended from time to time, and may not be pledged, sold or otherwise transferred except in accordance with the provisions thereof.”

The Parties acknowledge and agree that all restrictions contained in this Agreement are reasonable and valid and that all defences to the strict enforcement of such restrictions are hereby waived, and that the rights, privileges, restrictions and conditions set forth in this Agreement are special and unique such that a breach of any such rights, privileges, restrictions or conditions cannot adequately be compensated for by an award of damages. Accordingly, any Party will be entitled to temporary and permanent injunctive relief and to an order for specific performance against every other Party that is in breach of this Agreement without having to prove damages. Any remedy this Agreement sets forth or contemplates will be in addition to and not in substitution for or dependent upon any other remedy.

Anything to the contrary notwithstanding, all payments that the Partnership is required to make under this Agreement to a Partner will be subject to withholding of such amounts relating to income taxes, employment insurance premiums, Canada pension plan contributions, workers’ compensation premiums, other taxes and other amounts as the Partnership may reasonably determine it must withhold pursuant to any Applicable Law. In lieu of withholding such amounts, in whole or in part, the Partnership may, in its sole discretion, accept other provision for payment of taxes as required by law, provided it is satisfied that all requirements of law affecting its responsibilities to withhold such amounts have been satisfied.

Each Limited Partner will pay its own legal and other costs and expenses incurred in connection with the negotiation and finalization of this Agreement.

Each of the Limited Partners acknowledges that it has received or waived the opportunity to receive independent legal and tax advice in connection with this Agreement and with owning its respective Units.

This Agreement may be executed by facsimile or in portable document format (pdf) and delivered electronically and in two or more counterparts, each of which will be deemed an original and all of which will constitute one and the same instrument.

To the maximum extent permitted by Applicable Law, no Limited Partner will have any fiduciary duties to any other Partner of the Partnership, including as may result from a conflict of interest between any of PEGI, Pattern, PSP and the Partnership.
