2.3References

The division of this Plan into articles and sections and the insertion of headings are for convenience of reference only and shall not affect the construction or interpretation of this Plan.

2.5Code Section 409A

(a)It is intended that each Award granted under this Plan shall be exempt from or comply with the requirements of Code Section 409A. This Plan shall be construed, administered, and governed in a manner that effects such intent, and the Committee shall not take any action that would be inconsistent with such intent. Without limiting the foregoing, no Award shall be deferred, accelerated, extended, paid out, settled, adjusted, substituted, exchanged or modified in a manner that would cause the Award to fail to satisfy the conditions of an applicable exemption from, or compliance with, the requirements of Code Section 409A or otherwise would subject the Participant to additional tax imposed under Code Section 409A. Although the Company will use good faith efforts to avoid the imposition of taxation, interest and penalties under Code Section 409A, the tax treatment of the benefits provided under this Plan is not warranted or guaranteed. Neither the Company, its Subsidiaries nor their respective directors, officers, employees or advisers shall be held liable for any taxes, interest, penalties or other monetary amounts owed by a Participant (or any other individual claiming a benefit through the Participant) as a result of this Plan.

(b)To the extent required to comply with Code Section 409A, references in this Plan to a termination or cessation of employment or like terms shall mean a Separation from Service.

(c)Notwithstanding anything in the Plan to the contrary, if at the time of a Participant’s Separation from Service, the Participant is considered to be a Specified Employee, to the extent any Award is subject to the requirements of Code Section 409A and is payable upon the Participant’s Separation from Service, such payment shall not commence prior to the first Business Day following the date which is six months after the Participant’s Separation from Service (or if earlier than the end of the six month period, the date of the Participant’s death). For the avoidance of doubt, the provisions of this Section 2.5(c) shall not apply to any payment that becomes due prior to the Participant’s Separation from Service, any payment that becomes due as a result of the Participant’s death, or any payment with respect to an Award that qualifies for an exception to the requirements of Code Section 409A.

3.1Establishment

3.2No Additional Rights

Nothing herein contained shall be deemed to give any Person the right to be retained as an Employee or Director or to otherwise be retained in the Service of the Company or a Subsidiary. Units are not Common Shares and will not entitle a Participant to any shareholder rights, including voting rights, dividend entitlement or rights on liquidation, dissolution or winding-up of Fortis.

4.1Grant of Unit Awards

(a)The Committee, in its discretion, may, at any time and from time to time, grant Unit Awards in accordance with the terms and conditions hereof to Eligible Individuals; provided, however, that Unit Awards granted to Prospective Employees or Directors shall be conditioned on such individual actually becoming an Employee or Director, and such Unit Award shall not be considered granted or outstanding until such individual commences Service as an Employee or Director. The terms of a Participant’s Unit Award shall be set forth in the Participant’s Agreement.

(b)No certificates shall be issued with respect to Units. All Units granted hereunder shall be reflected in the Unit Account of the Participant.

(c)The Units in a Unit Account shall be credited with Dividend Equivalents. Dividend Equivalents shall be subject to the same terms and conditions as the Units in respect of which such Dividend Equivalents are credited. Notwithstanding the foregoing, the Committee shall have discretion to modify the terms and timing of payment relating to Dividend Equivalents or to determine that any Unit Award is not entitled to dividend equivalents, in each case as set forth in the applicable Agreement.

4.2Grant of Incentive Awards

(a)The Committee, in its discretion, may, at any time and from time to time, grant Incentive Awards in accordance with the terms and conditions hereof to Eligible Individuals; provided, however, that Incentive Awards granted to Prospective Employees or Directors shall be conditioned on such individual actually becoming an Employee or Director, and such Incentive Award shall not be considered granted or outstanding until such individual commences Service as an Employee or Director. The Payment Criteria and Payment Criteria Period shall be set forth in an Agreement authorized by the Committee.

(b)Incentive Awards may be earned, if at all, based upon the level of achievement of the Payment Criteria over the Payment Criteria Period, as determined by the Committee and as specified in the Agreement.

(c)Incentive Awards shall not be denominated in Units and shall only be paid in cash.

4.3Adjustments. In the event of any stock dividend, stock split, combination or exchange of shares, merger, consolidation, spin-off or other distribution (other than normal cash dividends) of Fortis’s assets to the shareholders, or any other change affecting the Common Shares, such proportionate adjustments, if any, as the Committee in its sole discretion may deem appropriate to reflect such change shall be made with respect to the number of Units outstanding (including, for the avoidance of doubt, Dividend Equivalents) under the Plan. In the event Fortis or the Company is not the surviving entity in a merger, consolidation or amalgamation with another entity or in the event of a liquidation, reorganization and in the absence of any surviving entity’s assumption of outstanding awards made under the Plan, the Committee may provide for appropriate settlements of Units.

4.4Committee Discretion. Subject to the terms and conditions of the Plan, the Committee shall determine the terms and conditions of any Awards in addition to those set forth herein at the time of grant or from time to time following the Grant Date, including any additional conditions with respect to the payment of Awards, which do not conflict with the Plan. The Committee may, subsequent to the Grant Date, waive any such term or condition or determine that it has been satisfied.

5.1Calculation of Payout Amount

(a)Performance-Based Units. Except as otherwise provided in the Plan or Agreement, subject to a Participant’s continued Service through the end of the Payment Criteria Period, upon the completion of the Payment Criteria Period, the Performance-Based Units shall be earned and vest, to the extent the Payment Criteria were achieved and based on the resulting Payout Percentage, in each case, as determined by the Committee, which such determination must be made as soon as reasonably practicable, and in any event, within 60 days, following the end of the Payment Criteria Period in accordance with the terms of the applicable Agreement. The Payout Amount shall be equal to the following:

A is that aggregate number of Units in the Participant’s Unit Account with respect to such Award on the last date of the Payment Criteria Period, determined by adding: (i) the Target Number of Units, as adjusted, if at all, in accordance with Section 4.3 and (ii) the Dividend Equivalents (if any) credited to the Participant’s Unit Account during the Payment Criteria Period;

(b)Service-Based Units. Except as otherwise provided in the Plan or Agreement, subject to a Participant’s continued Service through the Vesting Date, the Payout Amount shall be equal to the following:

(c)Incentive Awards. Except as otherwise provided in the Plan or Agreement, subject to Participant’s continued Service through the end of the Payment Criteria Period, upon the completion of a Payment Criteria Period, the Incentive Awards shall be earned and vest, to the extent the Payment Criteria were achieved and based on the resulting Payout Percentage, in each case, as determined by the Committee, which such determination must be made as soon as reasonably practicable, and in any event, within 60 days following the end of the Payment Criteria Period in accordance with the terms of the applicable Agreement.

Immediately after the payment contemplated in Section 5.1(a) or Section 5.1(b), the number of Units outstanding in a Participant’s Unit Account shall be reduced by (a) the number of Units (including Dividend Equivalents) so paid out and (b) if the payment was in respect of Performance-Based Units, the number of Performance-Based Units cancelled as a result of the failure, in full or in part, to satisfy the Payment Criteria.

5.2Payment of Payout Amount

6.1The treatment of Awards upon a Participant ceasing to be an Employee or Director of the Company, or in connection with a Change of Control, shall be as provided in the applicable Agreement or, if not set forth in the applicable Agreement, as otherwise determined by the Committee.

7.1Administration

(a)The Plan shall be administered by the Committee. Among other things, the Committee shall have full and complete authority to interpret the Plan, establish, amend and rescind any rules and regulations relating to the Plan, and make any other determinations that it deems necessary or desirable for the administration of the Plan. The Committee may correct any defect or supply any omission or reconcile any inconsistency in the Plan or any Agreement in the manner and to the extent the Committee deems necessary or desirable. Any decisions of the Committee relating to the interpretation and administration of the Plan, as described herein, shall lie within its sole and absolute discretion and shall be final, conclusive and binding on all parties concerned and their beneficiaries, legal representatives and successors, as applicable, and the shareholders of Fortis. No member of the Committee shall be liable for any action or determination made in good faith with respect to the Plan or any Award hereunder.

(b)In addition to any other powers set forth in the Plan, but subject to Code Section 409A and the provisions of the Plan, the Committee shall have the full and final power and authority, in its discretion to:

(i)amend, modify, or cancel any Award, or to waive any restrictions or conditions applicable to any Award;

(ii)    accelerate, continue, or defer the exercisability or Vesting of any Award or any shares acquired pursuant thereto;

(iii)     authorize, in conjunction with any applicable deferred compensation plan of the Company, that the receipt of cash subject to any Award under this Plan may be deferred under the terms and conditions of such deferred compensation plan; and

(iv)     determine the terms and conditions of Awards granted to Participants and whether such terms and conditions have been satisfied.

No amendment, modification, or cancellation of an outstanding Award or Agreement shall in any manner materially and adversely affect any then outstanding Award under the Plan without the consent of the Participant holding such Award, except as set forth in any Agreement relating to the Award, as set forth in Section 2.2 or 4.3 or to bring the Plan and/or an Award into compliance with the requirements of Code Section 409A or to qualify for an exemption under Code Section 409A.

(a)In exercising its authority under Section 7.1, the Committee shall from time to time ensure it is informed as to the terms and conditions of any similar plans of Fortis and Fortis’s other subsidiaries in order that it may consider such terms in exercising such authority.

7.2Unfunded Obligation

Unless otherwise determined by the Committee, the Plan will be an unfunded obligation of the Company and the Company’s obligations hereunder shall constitute general, unsecured obligations, payable solely out of its general assets, and no Participant or other Person shall have any right to any specific assets of the Company. The Company shall not segregate any assets for the purpose of funding its obligations with respect to the Awards granted hereunder and shall not be deemed to be a trustee of any amounts to be distributed or paid pursuant to the Plan. No liability or obligation of the Company under the Plan shall be deemed to be secured by any pledge of, or encumbrance on, any property or assets of the Company. To the extent any individual holds rights under the Plan, such rights (unless otherwise determined by the Committee) shall be no greater than the rights of an unsecured general creditor of the Company.

7.3Amendment, Suspension and Termination

The Plan may be amended, suspended or terminated at any time by the Board, in whole or in part, except as to rights already accrued hereunder unless the affected Participant consents to any such change in writing; provided, however, that an amendment, suspension or termination the effect of which is not adverse to such Participant shall not require such Participant’s consent. If the Plan is terminated, outstanding awards shall, at the discretion of the Committee, either (a) subject to Section 2.5, vest and become immediately payable in accordance with Section 5.2, or (b) remain outstanding and in effect in accordance with their applicable terms and conditions. In the event of a Change of Control, the Company shall pay all outstanding amounts in accordance with the applicable Agreement and the Plan will terminate as of the later of the effective date of such Change of Control or the completion of the payment of all Awards under the Plan.

The Company will be responsible for all costs relating to the administration of the Plan.

7.5Withholding Taxes

The Company shall withhold from any payment to or for the benefit of a Participant any amount required to comply with Applicable Law relating to the withholding of tax or the making of any other source deductions, including on the amount, if any, included in income of a Participant and may adopt and apply such rules and regulations as in its opinion will ensure that the Company will be able to so comply. To the extent that the Company is required under Applicable Law to withhold tax at any time other than upon payment of Awards pursuant to this Plan (for example, if payment is deferred pursuant to Section 7.6 hereof), then the Company shall have the right in its sole discretion to (a) require the Participant to pay or provide for payment of the required tax withholding, or (b) deduct the required tax withholding from any amount of salary, bonus, incentive compensation or other payment otherwise payable in cash to the Participant.

7.6Deferral

Notwithstanding anything contained herein to the contrary, but subject to Code Section 409A, Participants may elect to defer receipt of payment of the Awards in accordance with the terms, and subject to the conditions, of the Company’s Executive Deferred Compensation Plan (and any similar or successor plan that may be in effect from time to time).

8.1Clawback of Payout Amounts and Units

Notwithstanding any provisions in this Plan or the applicable Agreement to the contrary, all Awards granted hereunder shall be subject to any Company clawback policy in effect from time to time, as such policy may be amended.

9.1No Assignment

An Award is personal to the Participant and is non-assignable. No Award granted hereunder shall be pledged, hypothecated, charged, transferred, assigned or otherwise encumbered or disposed of by the Participant, whether voluntarily or by operation of law, otherwise than by testate succession or the laws of descent and distribution, and any attempt to do so will be null and void. During the lifetime of the Participant, an Award shall be redeemable only by the Participant and, upon the death of a Participant, the Person to whom the rights shall have passed by testate succession or by the laws of descent and distribution may receive payment of any Awards in accordance with the terms hereof.

9.2Currency

The value and number of Units determined in Section 4.1 with respect to an Award, all dividend equivalents payable with respect to an Award, all Payout Amounts with respect to an Award and all other amounts that may become payable with respect to an Award shall be calculated and paid in U.S. dollars.

9.3Successors and Assigns

The Plan shall be binding on all successors and assigns of the Company and a Participant including, if applicable, the estate of such Participant and the executor, administrator or trustee of such estate, or any receiver or trustee in bankruptcy or representative of the Participant’s creditors.
