| (a) | On or prior to the third Business Day prior to the Closing Date, Enbridge shall prepare and deliver to EIPLP a statement (the “Estimated Statement”) calculating and setting forth Enbridge’s good faith estimate of the (i) Estimated Working Capital, (ii) Estimated Third Party Indebtedness Balance and (iii) Estimated PP&E Balance. The Estimated Statement shall be prepared on a basis consistent with the sample calculation and related accounting principles set forth in Exhibit F (the “Sample Statement of Adjustments”).

| (b) | The consideration to be issued or paid (as applicable) by EIPLP to the Enbridge Entities as described in Section 2.2 shall be increased or decreased in accordance with this Section 2.5(b).

| (i) | Working Capital.

| (A) | If the Estimated Working Capital minus the Target Working Capital is a positive number, the Base Cash Consideration otherwise payable to the applicable Enbridge Entities shall be increased by an amount equal to the Estimated Working Capital minus the Target Working Capital.

| (B) | If the Estimated Working Capital minus the Target Working Capital is a negative number, the Base Cash Consideration otherwise payable to the applicable Enbridge Entities shall be decreased by an amount equal to the Target Working Capital minus the Estimated Working Capital.

| (ii) | Third Party Indebtedness.

| (A) | If the Target Third Party Indebtedness Balance minus the Estimated Third Party Indebtedness Balance is a positive number, the Base Cash Consideration otherwise payable to the applicable Enbridge Entities shall be increased by an amount equal to the Target Third Party Indebtedness Balance minus the Estimated Third Party Indebtedness Balance.

| (B) | If the Target Third Party Indebtedness Balance minus the Estimated Third Party Indebtedness Balance is a negative number, the Base Cash Consideration otherwise payable to the applicable Enbridge Entities shall be decreased by an amount equal to the Estimated Third Party Indebtedness Balance minus the Target Third Party Indebtedness Balance.

| (iii) | PP&E Expenditures.

| (A) | If the Estimated PP&E Balance minus the Target PP&E Balance is a positive number, the Base Cash Consideration otherwise payable to the applicable Enbridge Entities shall be increased by an amount equal to the Estimated PP&E Balance minus the Target PP&E Balance.

-22-

| (B) | If the Estimated PP&E Balance minus the Target PP&E Balance is a negative number, the Base Cash Consideration otherwise payable to the applicable Enbridge Entities shall be decreased by an amount equal to the Target PP&E Balance minus the Estimated PP&E Balance.

| (c) | For the purposes of determining the Working Capital of a Contributed Entity, the liability of a Contributed Entity for Taxes for a Straddle Period that is allocable to the portion of such taxable year or period ending immediately before the start of the Closing Date shall be determined (i) in the case of any property or ad valorem Taxes which are imposed on a periodic basis, rateably on a per diem basis, (ii) in the case of any Taxes imposed pursuant to the Tax Act or any similar provincial legislation, based on the assumption that the Straddle Period for the relevant Contributed Entity was a taxation year or fiscal period that ended immediately before the start of the Closing Date and in which the relevant Contributed Entity deducted the maximum amounts available to it under applicable Law in calculating its income or taxable income in respect of such notional taxation year or fiscal period and (iii) in the case of any other Taxes, based on an interim closing of the books of the relevant Contributed Entity as of the time which is immediately before the start of the Closing Date; provided that any transaction taking place, or item of income or gain arising, outside of the ordinary course of business on the Closing Date prior to the Closing shall be deemed for the purposes of this Section 2.5 to have taken place or arisen on the day immediately prior to the Closing Date and the Enbridge Entities Pre-Closing Transactions and the Enbridge Pre-Execution Transactions shall be deemed to have taken place prior to the Closing.

| (d) | At the same time as Enbridge delivers the Estimated Statement, Enbridge shall deliver to EIPLP its allocation of the Closing Adjustment Amount to the Enbridge Directly Contributed Entities (the “Enbridge Closing Adjustment Amount”) and the IPL Directly Contributed Entities (the “IPL Closing Adjustment Amount”).

| (e) | Notwithstanding the foregoing, if the Closing Adjustment Amount would result in either or both of the Enbridge Entities receiving cash consideration in excess of the amount of the Base Cash Consideration applicable to such Enbridge Entity, the applicable Enbridge Entity shall have the option to receive such excess amount, in whole or in part, in the form of additional Class C Units issued at a deemed price equal to the Issue Price.

| (f) | The total cash consideration amount to be paid at Closing by EIPLP to the Enbridge Entities, being the Base Cash Consideration as adjusted pursuant to this Section 2.5 by the Closing Adjustment Amount (net of any amount that is not paid in cash as a result of any exercise of the option contained in Section 2.5(e)), is referred to in this Agreement as the “Closing Cash Consideration”. The Closing Cash Consideration shall be subject to a Post-Closing Adjustment pursuant to the provisions of Section 2.6 and Section 2.7.

2.6 | Post-Closing Adjustment Process.

| (a) | Within 120 days following the Closing Date, Enbridge shall prepare and deliver to EIPLP a statement (the “Initial Statement”) calculating and setting forth in accordance with GAAP and on a basis consistent with the Sample Statement of Adjustments the actual Working Capital, Third Party Indebtedness Balance and PP&E Balance immediately before the start of the Closing Date in respect of the Contributed Entities. During the 90 days immediately following EIPLP’s receipt of the Initial Statement (the “Adjustment Review Period”), Enbridge shall permit EIPLP and its Representatives to review Enbridge’s working papers and any working papers of Enbridge’s independent accountants, in each case, relating to

-23-

| the preparation of the Initial Statement and the calculations related thereto, as well as all of the financial books, ledgers and records related thereto, and Enbridge shall make reasonably available to EIPLP the individuals responsible for and knowledgeable about the information used in, and the preparation or calculation of, the Initial Statement.

| (b) | In the event that EIPLP concludes that the Initial Statement or any amount set forth therein has not been prepared on the basis required by this Agreement, EIPLP shall submit a written notice to Enbridge on or prior to the expiration of the Adjustment Review Period (the “Notice of Adjustment Disagreement”), which notice shall set forth in reasonable detail the basis of EIPLP’s disagreement, the amounts involved and the proposed determination of the disputed amount. If no Notice of Adjustment Disagreement is received by Enbridge on or prior to the expiration date of the Adjustment Review Period, then the Initial Statement shall be deemed to have been accepted by EIPLP and shall become final and binding upon the Parties.

| (c) | If Enbridge and EIPLP have been unable to resolve all disagreements they may have with respect to the matters specified in the Notice of Adjustment Disagreement within 30 days of the receipt by Enbridge of such Notice of Adjustment Disagreement, either may notify the other in writing that the unresolved disagreements (the “Adjustment Disagreement”) shall be submitted for final and binding determination to an independent certified public accounting firm qualified and of national recognition in Canada as is mutually agreeable to Enbridge and EIPLP and that they cooperate in good faith to appoint promptly thereafter (the “Independent Accountant”).

| (d) | Within 30 days of the appointment of the Independent Accountant, Enbridge and EIPLP shall each submit to the Independent Accountant written statements setting forth in detail their respective positions with respect to the Adjustment Disagreement along with any relevant supporting documents. As soon as practicable thereafter, the Independent Accountant, acting as an expert and not as an arbitrator, will make a final determination, binding on the Parties, on a basis consistent with the Sample Statement of Adjustments, of the appropriate amount of each of the matters comprising the Adjustment Disagreement. Enbridge and EIPLP may only challenge the determination of the Independent Accountant in the case of manifest error or fraud on the part of the Independent Accountant. Notwithstanding Section 10.7 of this Agreement, any challenge permitted to be made in respect of the determination of the Independent Accountant shall be made in a court of competent jurisdiction sitting in Calgary, Alberta.

| (e) | The statement setting forth the Working Capital, Third Party Indebtedness Balance and PP&E Balance of the Contributed Entities that is final and binding on the Parties, as determined either through agreement of the Parties (deemed or otherwise), pursuant to Section 2.6(b) or through the determination of the Independent Accountant pursuant to Section 2.6(d), is referred to herein as a “Final Statement”, and the determination of the Working Capital, the Third Party Indebtedness Balance and the PP&E Balance of the Contributed Entities set forth in the Final Statement shall be referred to as the “Final Working Capital”, the “Final Third Party Indebtedness Balance” and the “Final PP&E Balance”, respectively.

| (f) | The cost of the Independent Accountant’s review and determination shall be shared equally by Enbridge and EIPLP.

-24-

2.7 | Payment of Post-Closing Adjustment

| (a) | The “Post-Closing Adjustment” shall be an amount equal to the sum of (i) the Final Working Capital minus the Estimated Working Capital, (ii) the Estimated Third Party Indebtedness Balance minus the Final Third Party Indebtedness Balance and (iii) the Final PP&E Balance minus the Estimated PP&E Balance. If the Post-Closing Adjustment is a positive amount, then EIPLP shall pay cash in such amount to the applicable Enbridge Entity. If the Post-Closing Adjustment is a negative amount, then the Enbridge Entities shall pay cash in such amount to EIPLP, without the issuance of any additional equity in respect thereof. Any such payment shall be made within three Business Days after the Final Statement becomes such, together with interest thereon, from the Closing Date through to the date on which the applicable Post-Closing Adjustment is paid, at the Interest Rate calculated and payable in accordance with Section 2.10. Any payment made pursuant to this Section 2.7(a) shall be treated as an adjustment to the Closing Cash Consideration made to the Enbridge Entities, and in connection with any such payment the Enbridge Entities shall be permitted to provide to EIPLP an allocation of such payment between the Enbridge Entities.

| (b) | Notwithstanding Section 2.7(a), if the Post-Closing Adjustment would result in either or both of the Enbridge Entities receiving aggregate cash consideration pursuant to this Agreement in excess of the amount of the Base Cash Consideration applicable to such Enbridge Entity, the applicable Enbridge Entity shall have the option to receive such excess amount, in whole or in part, in additional Class C Units issued at a deemed price equal to the Issue Price.

2.8 | Closing.

The Closing shall take place at the offices of Enbridge, 3000 Fifth Avenue Place, 425 - 1st Street S.W., Calgary, Alberta, T2P 3L8, on the later of (i) September 1, 2015 and (ii) the first Business Day of the first month following the day on which the last of the conditions set forth in Article VII shall be satisfied or waived in accordance with this Agreement (other than those conditions that by their nature are to be satisfied at Closing, but subject to the fulfillment or waiver of those conditions) or at such other time and place as Enbridge and EIPLP may agree (such date being the “Closing Date”) at 6:30 a.m. (Calgary time) or at such other time on the Closing Date as Enbridge and EIPLP may agree (such time being the “Closing Time”).

2.9 | Deliveries at Closing.

At the Closing, the Enbridge Entities shall deliver, or cause to be delivered, to the Fund Entities, the items set forth in Part A of Exhibit B and the Fund Entities shall deliver, or cause to be delivered, to the Enbridge Entities, the items set forth in Part B of Exhibit B.

2.10 | Interest.

All computations of interest with respect to any payment due to a Person under this Agreement shall be based on the Interest Rate on the basis of a year of 365 days or 366 days, as applicable, and the actual number of days (including the first day, but excluding the last day) occurring in the period for which such interest is payable. Whenever any payment under this Agreement will be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day, and such extension of time shall be included in the computation of payment of interest.

2.11 | Payments.

The Parties shall make any payment due to the others pursuant to this Article II by no later than 11:00 a.m. (Calgary time) on the day when due (unless otherwise consented to by the Person

-25-

to whom such payment is due). All payments shall be paid by wire transfer of immediately available funds to the account or accounts designated by or on behalf of the Person receiving such payment.

2.12 | Tax Elections.

EIPLP will, at the request of the Enbridge Entities, execute income tax elections under subsection 97(2) of the Tax Act with respect to the contribution by each Enbridge Entity of their respective Directly Contributed Equity Interests. Such elections will be prepared by the Enbridge Entities in accordance with the provisions of subsection 97(2) of the Tax Act and provided to EIPLP for execution. EIPLP’s execution of any election will not be indicative that such election is correct or complete in accordance with the Tax Act. EIPLP will execute and return any election to the Enbridge Entities within 30 days following receipt thereof. The Enbridge Entities shall be entitled to specify the “elected amount” in respect of the Directly Contributed Equity Interests for purposes of the Tax Act within the limits thereon imposed by the Tax Act and EIPLP will not be responsible for the proper completion, review or filing of any election forms or for any Taxes, interest or penalties resulting from the failure of the Enbridge Entities to properly complete or file such elections.

-26-

2.13 | Price Adjustment.

| (a) | If any Tax Authority should assess or reassess either Enbridge Entity for any income tax, or proposes such an assessment or reassessment, on the basis of a determination or an assumption that the quotient obtained when the aggregate fair market value of the IPL Directly Contributed Equity Interests on the Closing Date is divided by the aggregate fair market value of the IPL Directly Contributed Equity Interests and the Enbridge Directly Contributed Equity Interests on the Closing Date (the “Equity Ratio”) was an amount that differed from the quotient obtained when the aggregate fair market value of the IPL Consideration on the Closing Date is divided by the aggregate fair market value of the IPL Consideration and the Enbridge Consideration on the Closing Date (the “Consideration Ratio”); and

| (i) | such determination or assumption is acceptable to the Enbridge Entities; or

| (ii) | such determination or assumption is disputed by an Enbridge Entity and a final settlement is reached by such Enbridge Entity with the Tax Authority as to the aggregate fair market value of the Directly Contributed Equity Interests, the IPL Consideration and the Enbridge Consideration; or

| (iii) | such determination or assumption is disputed by an Enbridge Entity and a court of competent jurisdiction makes a final determination of the aggregate fair market value of the Directly Contributed Equity Interests, the IPL Consideration and the Enbridge Consideration,

any of which events in clauses (i), (ii) and (iii) above is herein called a “Final Determination”, then the number of Class C Units issued hereunder by EIPLP shall be adjusted and reallocated among the Enbridge Entities in accordance with Section 2.13(b). Any such adjustment shall be effective for all purposes from and after the Closing Date and Enbridge, IPL and EIPLP shall make all such other consequential adjustments as may be necessary to place Enbridge, IPL and EIPLP in the same position as they would have been if the adjustments contemplated in this Section 2.13 had been made at Closing.

| (b) | After any Final Determination, the number of Class C Units that were issued by EIPLP on the Closing Date will be reallocated as between IPL and Enbridge so as to minimize the difference between the Equity Ratio and the Consideration Ratio. The reallocation of the Class C Units contemplated by this Section 2.13(b) will be effected by EIPLP:

| (i) | cancelling the appropriate number of Class C Units issued to Enbridge and issuing an identical number of Class C Units to IPL where the Final Determination resulted in the Equity Ratio exceeding the Consideration Ratio; and

| (ii) | cancelling the appropriate number of Class C Units issued to IPL and issuing an identical number of Class C Units to Enbridge where the Final Determination resulted in the Consideration Ratio exceeding the Equity Ratio.

-48-

| made, (i) in the case of any property or ad valorem Taxes which are imposed on a periodic basis, rateably on a per diem basis, (ii) in the case of any Taxes imposed pursuant to the Tax Act or any similar provincial legislation, based on the assumption that the Straddle Period for the relevant Contributed Entity was a taxation year or fiscal period that ended immediately before the start of the Closing Date in which the relevant Contributed Entity deducted the maximum amounts available to it under applicable Law in calculating its income or taxable income in respect of such notional taxation year or fiscal period and (iii) in the case of any other Taxes, based on an interim closing of the books of the relevant Contributed Entity as of the time which is immediately before the start of the Closing Date; provided that any transaction taking place, or item of income or gain arising, outside of the ordinary course of business on the Closing Date before the Closing shall be deemed for the purposes of Section 6.7(a) to have taken place or arisen on the day immediately prior to the Closing Date and the Enbridge Entities Pre-Closing Transactions and the Enbridge Pre-Execution Transactions shall be deemed to have taken place prior to the Closing.

| arises that may give rise to a liability claim against a Contributed Entity prior to the Closing Date, and such claim or circumstance (i) is potentially covered by any of the Enbridge Policies and (ii) exceeds the applicable deductible under such Enbridge Policy, then Enbridge shall file a claim with the applicable insurance carriers and shall pay or cause to be paid to the applicable Contributed Entity any insurance proceeds received for such loss (less the amount of any deductible paid by Enbridge).

| (c) | Between the date hereof and the Closing Date, the Enbridge Entities shall not, and shall cause each Contributed Entity not to, voluntarily compromise, settle or adjust any amounts payable by reason of any losses or claims referenced in Section 6.16(a) or Section 6.16(b) in excess of [Dollar amount redacted as being commercially sensitive] in the aggregate without first obtaining the written consent of EIPLP, such consent not to be unreasonably withheld, conditioned or delayed.

Each of the Parties shall execute and deliver, or shall cause to be executed and delivered, such documents and other instruments and shall take, or shall cause to be taken, such further actions as may be reasonably required to carry out the provisions of this Agreement and give effect to the transactions contemplated hereby.

8.1 | Termination by Mutual Consent.

This Agreement may be terminated at any time prior to Closing by the mutual written consent of all of the Parties.

8.2 | Termination by Enbridge or EIPLP.

This Agreement may be terminated at any time prior to Closing by Enbridge or by EIPLP:

-56-

| (a) | by giving written notice of such termination to EIPLP, in the case of a termination by Enbridge, or to Enbridge, in the case of a termination by EIPLP, if Closing has not occurred by the Outside Date; provided, however, that the right to terminate this Agreement under this Section 8.2(a) shall not be available to Enbridge or EIPLP where the failure of the Enbridge Entities (in the case of Enbridge) or the failure of the Fund Entities (in the case of EIPLP), as applicable, to fulfill its obligations under this Agreement has caused or resulted in the failure of Closing to occur prior to the Outside Date;

| (b) | by giving written notice of such termination to EIPLP, in the case of a termination by Enbridge, or to Enbridge, in the case of a termination by EIPLP, if any court of competent jurisdiction or a Government Entity shall have issued an order, decree or ruling or taken any other action permanently restraining, enjoining or otherwise prohibiting any material part of the transactions contemplated hereby and such order, decree, ruling or other action shall have become final and non-appealable; provided that the right to terminate this Agreement under this Section 8.2(b) shall not be available to Enbridge or EIPLP where the failure of the Enbridge Entities (in the case of Enbridge) or the failure of Fund Entities (in the case of EIPLP), as applicable, to fulfill any of their obligations under this Agreement has caused or resulted in such order, decree, ruling or action; or

| (c) | by giving written notice of such termination to EIPLP, in the case of a termination by Enbridge, or to Enbridge, in the case of a termination by EIPLP, if the EIFH Resolution shall have failed to receive the requisite vote at the EIFH Shareholders’ Meeting (including any adjournment or postponement thereof).

8.3 | Termination by Enbridge.

This Agreement may be terminated at any time prior to Closing by Enbridge if there has been a breach of any representation, warranty, covenant or agreement made by the Fund Entities in this Agreement, or any such representation and warranty shall have become untrue after the date of this Agreement, such that the conditions set forth in Section 7.3(a) or Section 7.3(b) would not be satisfied, and such breach or condition is not curable or, if curable, is not cured prior to the earlier of (i) 30 calendar days after written notice thereof is given by Enbridge to EIPLP and (ii) one Business Day prior to the Outside Date; provided that the Enbridge Entities are not then in material breach of this Agreement so as to cause any of the conditions set forth in Section 7.1, Section 7.2(a) or Section 7.2(b) not to be satisfied.

8.4 | Termination by EIPLP.

This Agreement may be terminated at any time prior to Closing by EIPLP if there has been a breach of any representation, warranty, covenant or agreement made by the Enbridge Entities in this Agreement, or any such representation and warranty shall have become untrue after the date of this Agreement, such that the conditions set forth in Section 7.2(a) or Section 7.2(b) would not be satisfied, and such breach or condition is not curable or, if curable, is not cured prior to the earlier of (i) 30 calendar days after written notice thereof is given by EIPLP to Enbridge and (ii) one Business Day prior to the Outside Date; provided that the Fund Entities are not then in material breach of this Agreement so as to cause any of the conditions set forth in Section 7.1, Section 7.3(a) or Section 7.3(b) not to be satisfied.

8.5 | Effect of Termination.

In the event of the termination of this Agreement in accordance with this Article VIII, this Agreement shall thereafter become void and have no effect, and no Party shall have any liability to any other Party or its respective Affiliates, or its or their respective shareholders, unitholders, partners, directors, trustees, officers or employees, pursuant to this Agreement except for the obligations of the Parties contained in this Section 8.5, in Article X (and any related definitional

-57-

provisions set forth in Article I) and in the Confidentiality Agreement. Notwithstanding the foregoing, nothing in this Section 8.5 shall relieve any Party from liability for any wilful breach of this Agreement that arose prior to such termination.

ARTICLE IX

SURVIVAL; INDEMNIFICATION; CERTAIN REMEDIES

9.1 | Survival.

(a) The representations and warranties in Sections 3.1 (Organization and Good Standing), 3.2 (Authorization), 3.3 (Ownership of the Contributed Equity Interests), 3.4 (Non-Contravention), 4.1 (Organization and Good Standing), 4.2 (Authorization), 4.3 (Capitalization), 4.4 (Non-Contravention), 4.13(a), (b) and (c) (Properties) and 4.19 (No Brokers or Finders) of this Agreement (collectively, the “Enbridge Fundamental Representations”) shall survive indefinitely and the representations and warranties in Sections 5.1 (Organization and Good Standing), 5.2 (Authorization), 5.3 (Non-Contravention) and 5.7 (Issuance of Unit Consideration) of this Agreement (collectively, the “Fund Fundamental Representations”) shall survive indefinitely, (b) the representations and warranties in Sections 4.15 (Employment Matters) and 4.16 (Tax Matters) shall survive Closing until the date that is 90 days after the expiration of the applicable statute of limitations with respect thereto (taking into account any extensions or waivers thereof), (c) the representations and warranties in Sections 4.13(d) and (e) (Properties) and 4.14 (Environmental Matters) shall survive for a period of three years from the Closing Date and (d) all other representations and warranties in this Agreement shall survive the Closing for a period of 20 months from the Closing Date, at which time they will terminate (and no claims with respect to such representations and warranties shall be made by any Person for indemnification under Section 9.2 or Section 9.3 thereafter). All covenants and agreements that by their terms apply or are to be performed in whole or in part after Closing will survive for the period provided in such covenants and agreements, if any, or until fully performed. All covenants and agreements that by their terms apply or are to be performed in their entirety on or prior to Closing shall terminate at Closing. The period during which any representation and warranty survives is the “Survival Period” for such representation and warranty. Notwithstanding the foregoing, any representation or warranty that would otherwise terminate shall survive with respect to Losses in respect of which notice, in reasonable detail, is given pursuant to this Agreement prior to the end of the Survival Period for such representation or warranty until such Losses are finally resolved and paid. For the avoidance of doubt, Enbridge’s obligations with respect to the Retained Liabilities shall survive indefinitely.

9.2 | Indemnification by Enbridge.

| (a) | Subject to the limitations and exceptions set forth in Section 9.4, Enbridge hereby agrees that it shall be liable to and shall indemnify, defend and hold harmless, without duplication, EIPLP and its Subsidiaries (including, for greater certainty, the Contributed Entities following Closing) and their respective directors, trustees, officers and employees and their heirs, successors and permitted assigns, each in their capacity as such (the “EIPLP Indemnified Parties”) from and against any and all Losses actually suffered or incurred by any of the EIPLP Indemnified Parties, to the extent arising out of:

| (i) | from and after Closing, any breach of any representation or warranty in Article III or Article IV of this Agreement, made by Enbridge at the date of this Agreement or as of the Closing Date, for the Survival Period for such representation or warranty;

| (ii) | from and after Closing, any breach by the Enbridge Entities of any covenant or agreement made by the Enbridge Entities in this Agreement and required by this Agreement to be performed on or after Closing; and

| (iii) | from and after Closing, the Retained Liabilities.

-58-

| (b) | Subject to the limitations set forth in Section 9.4, Enbridge hereby agrees that it shall be liable to and shall indemnify, defend and hold harmless, without duplication, EIFH and its Affiliates and their respective directors, trustees, officers and employees and their heirs, successors and permitted assigns, each in their capacity as such (the “EIFH Indemnified Parties”) from and against any and all Losses actually suffered or incurred by any of the EIFH Indemnified Parties, to the extent arising directly from any misrepresentation in the Enbridge Information contained in the EIFH Circular.

| (c) | Enbridge hereby agrees that it shall be liable to and shall indemnify, defend and hold harmless, without duplication, EPI and Athabasca (the “Contributed Entity Indemnified Parties”) from and against any and all Losses actually suffered or incurred by any of the Contributed Entity Indemnified Parties, to the extent arising out of the obligations of the Contributed Entity Indemnified Parties under the Previous Drop-Down Tax Indemnities.

| (d) | For purposes of this Section 9.2, whether any representations and warranties have been breached (other than Sections 4.9(b) and 4.23), and the determination and calculation of any Losses resulting from such breach, shall be determined without giving effect to any qualification as to “materiality” (including the word “material” and the term “Material Adverse Effect”).

9.3 | Indemnification by the Fund Entities.

| (a) | Subject to the limitations set forth in Section 9.4, each of the Fund Entities hereby agrees that it shall be liable to and shall indemnify, defend and hold harmless the Enbridge Entities and their respective Affiliates, directors, trustees, officers and employees and their heirs, successors and permitted assigns, each in their capacity as such (the “Enbridge Indemnified Parties”) from and against any and all Losses actually suffered or incurred by any of the Enbridge Indemnified Parties, to the extent arising out of:

| (i) | from and after Closing, any breach of any representation or warranty in Article V, made by it at the date of this Agreement or as of the Closing Date, for the Survival Period for such representation or warranty; and

| (ii) | from and after Closing, any breach by it of any covenant or agreement made by it in this Agreement and required by this Agreement to be performed by it on or after Closing.

| (b) | For purposes of this Section 9.3, whether any representations and warranties have been breached, and the determination and calculation of any Losses resulting from such breach, shall be determined without giving effect to any qualification as to “materiality” (including the word “material” and the term “Material Adverse Effect”).

9.4 | Limitations.

| (a) | Except with respect to (i) Taxes or (ii) any Loss arising out of any breach of (A) any representation or warranty in Section 4.16 or (B) any of the Enbridge Fundamental Representations, Enbridge shall not be liable to the EIPLP Indemnified Parties for any Losses with respect to the matters contained in Section 9.2(a)(i) unless and until the aggregate of all Losses therefrom for which Enbridge would otherwise be liable exceeds an amount equal to $200,000,000 (the “Deductible”), after which Enbridge shall only be liable for Losses in excess of the Deductible.

| (b) | Except with respect to (i) Taxes or (ii) any Loss arising out of any breach of (A) any representation or warranty in Section 4.16 or (B) any of the Enbridge Fundamental

-59-

| Representations, Enbridge shall not be liable to the EIPLP Indemnified Parties with respect to the matters contained in Section 9.2(a)(i) for any individual Loss (or series of related Losses arising from a common set of facts), except to the extent such individual Loss (or series of related Losses arising from a common set of facts) exceeds $4,000,000 (the “Mini-Basket”), and any such individual Losses (or series of related Losses arising from a common set of facts) not in excess of the Mini-Basket will not be aggregated for purposes of calculating the Deductible.

| (c) | With respect to any Loss arising out of any breach of any representation or warranty in Sections 4.13(a), (b) and (c), Enbridge shall not be liable to the EIPLP Indemnified Parties pursuant to Section 9.2(a)(i) for any such individual Loss, except to the extent such individual Loss exceeds $2,000,000, and any such individual Losses not in excess of such amount will not be aggregated for purposes of calculating the Deductible.

| (d) | Except with respect to any Loss arising out of any breach of any of the Fund Fundamental Representations, the Fund Entities shall not be liable to the Enbridge Indemnified Parties for any Losses with respect to the matters contained in Section 9.3(a)(i) unless and until the aggregate of all Losses therefrom for which the Fund Entities would otherwise be liable exceeds an amount equal to the Deductible, after which the Fund Entities shall only be liable for Losses in excess of the Deductible.

| (e) | Except with respect to any Loss arising out of any breach of any of the Fund Fundamental Representations, the Fund Entities shall not be liable to the Enbridge Indemnified Parties with respect to the matters contained in Section 9.3(a)(i) for any individual Loss (or series of related Losses arising from a common set of facts), except to the extent such individual Loss (or series of related Losses arising from a common set of facts) exceeds the Mini-Basket, and any such individual Losses (or series of related Losses arising from a common set of facts) not in excess of the Mini-Basket will not be aggregated for purposes of calculating the Deductible.

| (f) | In no event shall Enbridge’s aggregate liability to the EIPLP Indemnified Parties for Losses with respect to the matters contained in Section 9.2(a)(i) exceed $4,500,000,000, except with respect to:

| (i) | any Loss arising out of any breach of any representation or warranty in Section 4.16 or for Taxes, in which case there will be no limit on Enbridge’s liability to the EIPLP Indemnified Parties pursuant to Section 9.2(a)(i) for such Losses; and

| (ii) | any Loss arising out of any breach of any of the Enbridge Fundamental Representations, in which case Enbridge’s aggregate liability to the EIPLP Indemnified Parties pursuant to Section 9.2(a)(i) for such Losses shall not exceed an amount equal to the aggregate of (A) the Cash Consideration plus (B) an amount equal to the Unit Consideration multiplied by the Market Price on the Closing Date.

| (g) | In no event shall the Fund Entities’ aggregate liability to the Enbridge Indemnified Parties for Losses with respect to the matters contained in Section 9.3(a)(i) exceed $4,500,000,000, except with respect to any Loss arising out of any breach of any of the Fund Fundamental Representations, in which case the Fund Entities’ aggregate liability to the Enbridge Indemnified Parties pursuant to Section 9.3(a)(i) for such Losses shall not exceed an amount equal to the aggregate of (A) the Cash Consideration plus (B) an amount equal to the Unit Consideration multiplied by the Market Price on the Closing Date.

-60-

| (h) | Notwithstanding anything herein to the contrary, no Indemnified Party shall be entitled to indemnification or reimbursement under any provision of this Agreement for any amount to the extent such Person or its Affiliate has been indemnified or reimbursed for such amount under any other provision of this Agreement. Without limiting the generality of the foregoing, Enbridge’s liability, if any, in respect of Pre-Existing Environmental Issues shall be governed exclusively by the Environmental Indemnity Agreement and Section 9.2(a)(i) shall not apply thereto.

| (i) | Notwithstanding anything to the contrary in this Agreement, in no event shall an Indemnifying Party be liable under this Article IX for any exemplary, punitive, special, consequential, incidental or indirect damages, including lost profits or diminution of value or any loss of goodwill or possible business after Closing, whether actual or prospective, except to the extent such damages are asserted by a third party in any Third Party Claim for which an Indemnified Party is entitled to indemnification under this Agreement.

| (j) | Each Indemnified Party shall use commercially reasonable efforts to mitigate their respective Losses upon and after becoming aware of any event or condition that would reasonably be expected to give rise to any Losses that are indemnifiable hereunder; provided that the Indemnified Party shall be fully reimbursed for any Losses incurred by the Indemnified Party arising out of or in respect to such mitigation. In the event an Indemnified Party fails to so mitigate an indemnifiable Loss, the Indemnifying Party shall have no liability for any portion of such Loss that reasonably could have been avoided had the Indemnified Party made such efforts. Without limiting the generality of the foregoing, after an Indemnified Party acquires knowledge of any fact or circumstance that results in or reasonably would be expected to result in an indemnified Loss or a Third-Party Claim for which the Indemnifying Party may have Liability to such Indemnified Party, such Indemnified Party shall notify the Indemnifying Party promptly and implement such reasonable actions as the Indemnifying Party shall request in writing for the purposes of mitigating the possible Losses arising therefrom.

9.5 | Third-Party Claim Indemnification Procedures.

| (a) | In the event that any written claim or demand for which an Indemnifying Party may have liability to any Indemnified Party hereunder is asserted against or sought to be collected from any Indemnified Party by a third party (a “Third-Party Claim”) such Indemnified Party shall promptly, but in no event more than ten days following such Indemnified Party’s receipt of a Third-Party Claim, notify the Indemnifying Party whom indemnification is sought in writing of such Third-Party Claim, the amount or the estimated amount of damages sought thereunder to the extent then ascertainable (which estimate shall not be conclusive of the final amount of such Third-Party Claim), any other remedy sought thereunder, any relevant time constraints relating thereto and, to the extent practicable, any other material details pertaining thereto (a “Claim Notice”). However, the failure to give prompt notice will not affect the rights or obligations of the Indemnifying Party except and only to the extent that, as a result of such failure, the Indemnifying Party was prejudiced. The Indemnifying Party shall have 15 days (or such lesser number of days set forth in the Claim Notice as may be required by any appropriate proceedings) after receipt of the Claim Notice (the “Notice Period”) to notify the Indemnified Party that it desires to defend the Indemnified Party against such Third-Party Claim. For purposes of this Article IX, any existing or future claims related to Taxes under Section 6.7 or the Retained Liabilities shall be subject to the same procedures as Third-Party Claims.

| (b) | In the event that the Indemnifying Party notifies the Indemnified Party within the Notice Period that it desires to defend the Indemnified Party against a Third-Party

-61-

| Claim, the Indemnifying Party shall have the right to defend the Indemnified Party by appropriate proceedings and shall have the sole power to direct and control such defense at its expense. Once the Indemnifying Party has duly assumed the defense of a Third-Party Claim, the Indemnified Party shall have the right, but not the obligation, to participate in any such defense and to employ separate counsel of its choosing. The Indemnified Party shall participate in any such defense at its expense unless the Indemnifying Party and the Indemnified Party are both named parties to the proceedings and the Indemnified Party shall have reasonably concluded, based on the advice of outside counsel, that representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them, in which case the Indemnified Party may participate in such defense and employ a single separate counsel at the Indemnifying Party’s expense. The Indemnifying Party shall not, without the prior written consent of the Indemnified Party, settle, compromise or offer to settle or compromise any Third-Party Claim on a basis that would result in (i) the imposition of a consent order, injunction or decree that would restrict the future activity or conduct of the Indemnified Party or any of its Affiliates or (ii) a finding or admission of a violation of Law or violation of the rights of any Person by the Indemnified Party or any of its Affiliates.

| (c) | If the Indemnifying Party elects not to defend the Indemnified Party against a Third-Party Claim, whether by not giving the Indemnified Party timely notice of its desire to so defend or otherwise, the Indemnified Party shall have the right, but not the obligation, to assume its own defense; it being understood that the Indemnified Party’s right to indemnification for a Third-Party Claim shall not be adversely affected by assuming the defense of such Third-Party Claim. The Indemnified Party shall not settle a Third-Party Claim without the consent of the Indemnifying Party, which consent shall not be unreasonably withheld, conditioned or delayed.

| (d) | The Indemnified Party and the Indemnifying Party shall cooperate in order to ensure the proper and adequate defense of a Third-Party Claim, including by providing access to each other’s relevant business records and other documents and employees.

| (e) | The Indemnified Party and the Indemnifying Party shall use commercially reasonable efforts to avoid production of confidential information (consistent with applicable Law), and to cause all communications among employees, counsel and others representing any party to a Third-Party Claim to be made so as to preserve any applicable solicitor-client privileges. For the avoidance of doubt, nothing in this Section 9.5 shall be construed as a waiver by an Indemnified Party or an Indemnifying Party of any privilege, including any privilege associated with separate counsel as described herein.

9.6 | Payments.

The Indemnifying Party shall pay all amounts payable pursuant to this Article IX or Section 6.7, by wire transfer of immediately available funds, promptly following receipt from an Indemnified Party of a bill, together with all accompanying reasonably detailed back-up documentation, for a Loss that is the subject of indemnification hereunder, unless the Indemnifying Party in good faith disputes the Loss, in which event it shall so notify the Indemnified Party (provided that, in the event of a good faith dispute with respect to a Loss, the Indemnifying Party shall promptly pay the portion of such Loss, if any, that is not subject to dispute). In any event, the Indemnifying Party shall pay to the Indemnified Party, by wire transfer of immediately available funds, the amount of any Loss for which it is liable hereunder no later than 30 days following any final determination of such Loss and the Indemnifying Party’s liability therefor. A “final determination” shall exist when (a) the parties to the dispute have reached an agreement in

-62-

writing or (b) an arbitration panel shall have made a final and non-appealable determination in accordance with Section 10.7.

Notwithstanding the foregoing, if an amount or amounts payable pursuant to this Article IX or Section 6.7 would result in either or both of the Enbridge Entities receiving a cash payment that, when aggregated with the Cash Consideration received by such Enbridge Entity, would result in such Enbridge Entity receiving aggregate cash payments under this Agreement in excess of the amount of the Base Cash Consideration applicable to such Enbridge Entity, then the applicable Enbridge Entity shall have the option to receive payment for such amount, in whole or in part, in the form of additional Class C Units issued at a deemed price equal to the Market Price per unit.

9.7 | Characterization of Indemnification Payments.

All payments made by an Indemnifying Party to an Indemnified Party in respect of any claim pursuant to Section 9.2 or Section 9.3 hereof shall be treated as adjustments to the Cash Consideration to the maximum extent permitted by applicable Tax Law. To the extent such payments cannot be treated as adjustments to the Cash Consideration they will be treated as contributions of capital to, or distributions of capital by, EIPLP. No change in the number or type of units of EIPLP held by any Person and no adjustment to the “Capital Contribution” (as that term is used in the EIPLP Partnership Agreement) of any unit of EIPLP shall result from a contribution or distribution of capital described in this Section 9.7.

9.8 | Adjustments to Losses.

| (a) | Insurance. In calculating the amount of any Loss, the proceeds actually received by the Indemnified Party or any of its Affiliates under any insurance policy or pursuant to any claim, recovery, settlement or payment by or against any other Person, net of any actual costs or expenses incurred in connection with securing or obtaining such proceeds, shall be deducted. In the event that an Indemnified Party has any rights against a third party with respect to any occurrence, claim or Loss that results in a payment by an Indemnifying Party under this Article IX, such Indemnifying Party shall be subrogated to such rights to the extent of such payment; provided that until the Indemnified Party recovers full payment of the Loss, any and all claims of the Indemnifying Party against any such third party on account of said indemnity payment are hereby expressly made subordinate and subject in right of payment to the Indemnified Party’s rights against such third party. Without limiting the generality or effect of any other provision hereof, each Indemnified Party and Indemnifying Party shall duly execute upon request all instruments reasonably necessary to evidence and perfect the subrogation and subordination rights detailed herein, and otherwise cooperate in the prosecution of such claims.

| (b) | Cash Consideration Adjustment. In calculating the amount of any Loss for which EIPLP is entitled to indemnification hereunder, the amount of any reserve or other negative provision related to such Loss shall be deducted to the extent reflected in the Final Statement and taken into account for any adjustment to the Cash Consideration or other adjustment in accordance with Section 2.5 and Section 2.6.

| (c) | Taxes. In calculating the amount of any Loss, there shall be deducted an amount equal to any Tax benefit (including the utilization of a Tax loss or Tax credit carried forward) as a result of such Loss by the Party claiming such Loss. The amount of adjustment for any such Tax benefit shall equal (i) in the case of a Tax deduction, (A) the amount of the Tax deduction multiplied by (B) the applicable combined federal and provincial corporate income tax rates in effect for the year in which the applicable indemnity payment is made or (ii) in the case of a Tax credit, 100%. In the case of any Tax deduction that will be recognized, or any Tax credit that will be

-63-

| utilized, in taxable years after the year in which the indemnity payment is made, the Tax benefit shall be discounted using a discount rate equal to 5% per annum.

| (d) | Reimbursement. If an Indemnified Party recovers an amount from a third party in respect of a Loss that is the subject of indemnification hereunder after all or a portion of such Loss has been paid by an Indemnifying Party pursuant to this Article IX, the Indemnified Party shall promptly remit to the Indemnifying Party the amount, if any, by which (i) the sum of (A) the amount paid by the Indemnifying Party to such Indemnified Party in respect of such Loss plus (B) the amount received from the third party in respect thereof, exceeds (ii) the full amount of the Indemnifying Party’s portion of such Loss.

| (e) | Net Financial Benefit. To the extent not otherwise addressed in this Section 9.8, no Indemnifying Party shall be liable under this Article IX in respect of any Losses suffered by any Indemnified Party to the extent there are any offsetting savings by or net financial benefits to such Indemnified Party arising from such Losses or the facts, matters, events or circumstances giving rise to such Losses.

9.9 | Remedies; Exclusive Remedy.

Except in the case of fraud and as otherwise provided in Section 10.9, the rights and remedies under this Article IX and the Environmental Indemnity Agreement are exclusive and in lieu of any and all other rights and remedies that the Fund Entities may have against the Enbridge Entities and that the Enbridge Entities may have against the Fund Entities under this Agreement or otherwise with respect to the Contributed Entities, the Contributed Equity Interests or any breach of any representation or warranty or any failure to perform any covenant or agreement set forth in this Agreement. Except in the case of fraud and as otherwise provided in Section 10.9, each of the Parties expressly waives any and all other rights, remedies and causes of action it or its Affiliates may have against any other Party and its respective Affiliates now or in the future under any Law with respect to the transactions contemplated hereby. The remedies expressly provided in this Agreement shall constitute the sole and exclusive basis for and means of recourse between the Parties with respect to the transactions contemplated hereby.

9.10 | Tax Indemnification Matters.

| (a) | If any Tax Authority should, at any time, issue an assessment or reassessment to a Contributed Entity the basis of which will, in whole or in part, give rise to an indemnity for Taxes pursuant to Section 6.7 or this Article IX (a “Tax Indemnity”), then Enbridge shall pay the amount of the assessment or reassessment that relates to the Tax Indemnity to the applicable Tax Authority on behalf of the applicable Contributed Entity, within the time period specified for the payment of such amount under applicable Law. Payment of all or any portion of such amount by Enbridge to the Tax Authority can be deferred in accordance with applicable Law, with the prior written consent of the applicable Contributed Entity, which consent shall not unreasonably be withheld, where Enbridge has:

| (i) | undertaken the contestation of the matter to which the Tax Indemnity relates in accordance with Section 9.5;

| (ii) | taken such action, to the satisfaction of the applicable Contributed Entity, acting reasonably, which will prevent the applicable Tax Authority from taking any collection action in relation to the matter to which the Tax Indemnity relates and the applicable Tax Authority has not taken any such collection action; and

| (iii) | provided written acknowledgement, to the satisfaction of the applicable Contributed Entity, acting reasonably, that Enbridge will indemnify and

-64-

| hold the applicable Contributed Entity harmless from and against any and all Losses which the applicable Contributed Entity may incur or suffer as a consequence of the deferral of the payment of all or any portion of such amount by Enbridge.

Notwithstanding the foregoing, if:

| (iv) | the applicable Tax Authority subsequently takes any collection action with respect to all or any part of the amount of the assessment or reassessment giving rise to the matter to which the Tax Indemnity relates; or

| (v) | under applicable Law, the ability to defer the payment of all or any part of the amount of the assessment or reassessment giving rise to the matter to which the Tax Indemnity relates ceases to be applicable,

then Enbridge shall promptly pay such amount to the applicable Tax Authority. Enbridge shall be solely responsible for, and shall indemnify the applicable Contributed Entity from and against, any and all interest that accrues during any period during which payment of the amount of such Taxes has been deferred.

| (b) | To the extent that Enbridge may be liable for indemnification for any Taxes under Section 6.7 and this Article IX, Enbridge shall only be liable under Section 6.7; provided, however, that the procedures specified in Section 9.5 shall be applicable to such claim.

10.4 | Entire Agreement.

Other than the Confidentiality Agreement and the Environmental Indemnity Agreement, this Agreement (including all Exhibits) and the other Transaction Documents contain the entire agreement among the Parties with respect to the subject matter hereof and thereof and supersede all prior agreements and understandings, oral or written, with respect to such matters.

10.5 | Fulfillment of Obligations.

Any obligation of any Party under this Agreement or any of the other Transaction Documents that is performed, satisfied or fulfilled completely by an Affiliate of such Party shall be deemed to have been performed, satisfied or fulfilled by such Party.

10.6 | Expenses.

Except as otherwise expressly provided in this Agreement, whether or not the transactions contemplated by this Agreement are consummated, all costs and expenses incurred in connection with this Agreement and the transactions contemplated hereby shall be borne by the Party incurring such costs and expenses.

10.7 | Dispute Resolution.

| (a) | Subject to the following provisions, any and all disputes arising out of or in connection with, or in respect of any legal relationship associated with or derived from, this Agreement (other than disputes contemplated by Section 2.6) shall be finally determined by arbitration administered by the International Centre for Dispute Resolution (“ICDR”) in accordance with its Canadian Dispute Resolution Rules and Procedures (“ICDR Rules”). The place of arbitration shall be Calgary, Alberta, Canada. The language of the arbitral proceedings shall be English. Judgment upon any award(s) rendered by the arbitrator(s) may be filed in any court of competent jurisdiction and may be enforced by any party as a final judgment in such court. In addition to the ICDR Rules, the Parties agree that the arbitration shall be conducted according to the IBA Rules on the Taking of Evidence in International Commercial Arbitration.

| (b) | There shall be three arbitrators, one nominated by the claimant(s) in the request for arbitration, the second nominated by the respondent(s) within 30 days of receipt of the request for arbitration, and the third, who shall act as president of the

-67-

| arbitral tribunal, nominated by the Parties within 30 days of the appointment of the second arbitrator. If any arbitrators are not nominated within these time periods, the ICDR shall make the appointment(s) in accordance with the ICDR Rules.

| (c) | The arbitrators shall award to the prevailing Party, if any, as determined by the arbitrators, its reasonable fees, costs and expenses. The prevailing Party shall also be entitled to its fees, costs and expenses in any action to confirm and/or enforce any arbitral award in any judicial proceedings.

| (d) | The final award shall be rendered as soon as reasonably practicable after the commencement of the arbitration taking into consideration the size, nature and complexity of the matters in dispute and the Parties’ intention to achieve a just, timely and cost effective determination of the matters in dispute.

| (e) | Where the subject matter of a dispute (the “Subject Dispute”) pertains to the same or substantially related subject matter of one or more disputes being arbitrated under any other agreement(s) (the “Other Disputes”) and one or more of the parties to such other agreement(s) are also Parties, or Affiliates of Parties, to this Agreement, the Subject Dispute and the Other Disputes shall be consolidated and conducted as a single arbitration.

| (f) | Except as required by Law or as required for recognition and enforcement of the arbitral decision and award, neither a Party nor an arbitrator may disclose the existence, content or results of any arbitration hereunder without the prior written consent of all of the Parties. Any documents submitted to the arbitrators shall be kept confidential and shall not be disclosed, except that any such documents may be disclosed in connection with any action to collect the award, to protect or pursue a legal right, to enforce or challenge an award in legal proceedings before a court or other judicial authority or if any such documents are discoverable or admissible in any action in court contemplated by this Agreement.

10.8 | Governing Law; Disputes.

This Agreement, and all claims or causes of action (whether in contract or tort or both) that may be based upon, arise out of or relate to this Agreement or the negotiation, execution or performance of this Agreement (including any claim or cause of action based upon, arising out of or related to any representation or warranty made in or in connection with this Agreement), will be construed in accordance with and governed by the laws of the Province of Alberta without regard to principles of conflicts of laws. Any dispute among the Parties regarding the interpretation of or performance under this Agreement shall be resolved exclusively in accordance with Section 2.6, Section 10.7 or Section 10.9, as applicable.

10.9 | Specific Performance.

Notwithstanding Section 10.7, each of the Parties acknowledges that its obligations hereunder are unique and that remedies at law, including monetary damages, will be inadequate in the event it should default in the performance of its obligations under this Agreement. Accordingly, in the event of any breach of any agreement, representation, warranty or covenant set forth in this Agreement, a Party, in the case of a breach by a different Party, shall be entitled to equitable relief, without the proof of the insufficiency of damages, including in the form of an injunction or injunctions or orders for specific performance to prevent breaches of this Agreement and to order the defaulting Party to affirmatively carry out its obligations under this Agreement, and each of the Parties hereby waives any defense to the effect that a remedy at law would be an adequate remedy for such breach. Such equitable relief shall be in addition to any other remedy to which the Parties are entitled to at law or in equity as a remedy for such non-performance, breach or threatened breach. Each of the Parties hereby waives any requirements for the securing or posting of any bond with respect to such equitable remedy. The foregoing shall not be deemed to be or

-68-

construed as a waiver or election of remedies by any of the Parties, each of whom expressly reserves any and all rights and remedies available to it at Law or in equity in the event of any breach or default by the others under this Agreement prior to Closing on or before which the relevant obligation is required to be performed.

10.10 | Fund Disclaimer.

The Parties hereto acknowledge that EMSI is entering into this Agreement in its capacity as agent on behalf of the Fund and the obligations of the Fund hereunder shall not be personally binding upon the trustees of the Fund (the “Fund Trustees”), EMSI, any of the unitholders of the Fund (“Fund Unitholder”) or any annuitant, subscriber or beneficiary under a plan of which a Fund Unitholder is a trustee or carrier (a “Fund annuitant”) and that any recourse against the Fund, the Fund Trustees, EMSI, any Fund Unitholder or Fund annuitant in any manner in respect of any indebtedness, obligation or liability of the Fund arising hereunder or arising in connection herewith or from the matters to which this Agreement relates, if any, including without limitation claims based on negligence or otherwise tortious behaviour, shall be limited to, and satisfied only out of, the Fund Property as defined in the EIF Trust Indenture.

10.11 | ECT Disclaimer.

The Parties acknowledge that EMSI is entering into this Agreement in its capacity as agent on behalf of ECT and the obligations of ECT hereunder shall not be personally binding upon any of the trustees of ECT (the “ECT Trustees”), EMSI, any of the unitholders of ECT (“ECT Unitholders”) or any annuitant, subscriber or beneficiary under a plan of which an ECT Unitholder is a trustee or carrier (a “ECT annuitant”) and that any recourse against ECT, the ECT Trustees, EMSI, any ECT Unitholder or any ECT annuitant in any manner in respect of any indebtedness, obligation or liability of ECT arising hereunder or arising in connection herewith or from the matters to which this Agreement relates, if any, including without limitation claims based on negligence or otherwise tortious behaviour, shall be limited to, and satisfied only out of, the Trust Property as defined in the ECT Trust Indenture.

10.12 | Counterparts.

This Agreement may be executed in one or more counterparts, each of which shall be deemed an original, and all of which shall constitute one and the same agreement. A signed copy of this Agreement delivered by facsimile, e-mail or other means of electronic transmission shall be deemed to have the same legal effect as delivery of an original signed copy of this Agreement.

10.13 | Headings.

The heading references herein and the table of contents hereof are for convenience purposes only, and shall not be deemed to limit or affect any of the provisions hereof.

10.14 | Severability.

The provisions of this Agreement shall be deemed severable and the invalidity or unenforceability of any provision shall not affect the validity or enforceability of the other provisions hereof. If any provision of this Agreement, or the application thereof to any Person or any circumstance, is invalid or unenforceable, (a) a suitable and equitable provision shall be substituted therefor in order to carry out, so far as may be valid and enforceable, the intent and purpose of such invalid or unenforceable provision and (b) the remainder of this Agreement and the application of such provision to other Persons or circumstances shall not be affected by such invalidity or unenforceability, nor shall such invalidity or unenforceability affect the validity or enforceability of such provision, or the application thereof, in any other jurisdiction.
