2015 RESTRICTED STOCK UNIT GRANT AGREEMENT

THIS RESTRICTED STOCK UNIT GRANT AGREEMENT (this “Agreement”) is made as of the date in the box above labeled “Date of Grant” by Huntington Bancshares Incorporated, a Maryland corporation and its subsidiaries (the “Company”), and is hereby communicated to the employee named in the box above (the “Employee”). Undefined capitalized terms used in this Agreement shall have the meanings set forth in the Company’s 2015 Long-Term Incentive Plan as may be amended from time to time (the “Plan”).

WHEREAS, the Company maintains the Plan.

WHEREAS, pursuant to Article 8 of the Plan, the Committee may grant awards of Restricted Stock Units to employees, and have such grants settled in shares of the Company’s common stock (“Shares”).

WHEREAS, the Company desires to compensate the Employee with a grant of Restricted Stock Units for the Employee’s future services to the Company.

NOW, THEREFORE, in consideration of the premises, the Company grants the Employee an Award of Restricted Stock Units under the following terms and conditions:

The Company, by authority of the Committee, hereby grants to the Employee an Award of the number of Restricted Stock Units identified above (the “Grant”) to be issued in accordance with all of the terms and conditions set forth in this Agreement and the Plan. The Restricted Stock Units will be a bookkeeping entry (the “RSU Account”), and each Restricted Stock Unit shall be equivalent to one Share. All terms and conditions set forth in the Plan are deemed to be incorporated herein in their entirety.

The number of Restricted Stock Units granted pursuant to this Agreement shall be credited to the Employee’s RSU Account. Each RSU Account shall be maintained on the books

Restricted Stock Unit Grant Agreement

of the Company until full payment of the balance thereof has been made to the Employee (or the Employee’s beneficiaries if the Employee is deceased). No funds shall be set aside or earmarked for any RSU Account, which shall be purely a bookkeeping device.

(a) The Employee’s RSUs shall vest only if both (i) the Employee satisfies the service-based vesting requirements in subsections (b), (c), or (d) below, as applicable, and (ii) the Committee certifies that the performance-based vesting requirement in subsection (e) below has been achieved.

(b) Except as provided in this Agreement, the Employee’s Restricted Stock Units shall vest as follows:

(1) If the Employee is continuously employed by the Company through the third anniversary of the Date of Grant, 50% of the Employee’s Restricted Stock Units in the Employee’s Restricted Stock Unit Account will vest on such date.

(2) If the Employee is continuously employed by the Company through the fourth anniversary of the Date of Grant, the remaining 50% of the Employee’s Restricted Stock Units in the Employee’s Restricted Stock Unit Account will vest on such date.

(c) Notwithstanding any provision in Section 3(b) above to the contrary, if, on or after the date that is six months after the Date of Grant, and before the fourth anniversary of the Date of Grant, the Employee’s employment or service with the Company terminates because of a Permitted Termination, the Employee shall vest in a prorated number of Shares (with any fractional Shares rounded up to the next whole number) equal to the number of Restricted Stock Units subject to Grant times one of the following two fractions, as applicable:

(1) If the Employee terminates service on or before the third anniversary of the Date of Grant, the numerator of the fraction shall be the number, which in no event shall be greater than 36, of all full and partial months (with partial months being counted as full months) that passed beginning with the month that contains the Date of Grant and ending with the month in which the Employee’s termination occurred. The denominator of the fraction shall be 72.

(2) If the Employee terminates service after the third anniversary of the Date of Grant but before the fourth anniversary of the Date of Grant, the numerator of the fraction shall be the number, which in no event shall be greater than 12, of all full and partial months (with partial months being counted as full months) that passed beginning with the month that contains the third anniversary of the Date of Grant and ending with the month in which the Employee’s termination occurred. The denominator of the fraction shall be 24. The number of shares in which the Employee vests under this subsection (c)(2) shall vest in addition to the number of shares previously vested under subsection (b)(1) above.

Huntington Bancshares Incorporated

Restricted Stock Unit Grant Agreement

For purposes of this Agreement, a “Permitted Termination” means (i) the Employee’s employment or service with the Company terminates due to Early Retirement, Disability, or death or (ii) the Company terminates the Employee without Cause (as defined in Section 2.5 of the Plan). For purposes of this Agreement and notwithstanding any provision of the Plan, including Section 2.38 of the Plan, to the contrary, “Early Retirement” means that the Employee has terminated service with the Company for any reason other than Cause on or after attainment of age 55 and completion of at least 10 years of service.

(d) Notwithstanding any provision in Section 3(b) or 3(c) above to the contrary, if, on or after the date that is six months after the Date of Grant, and before the fourth anniversary of the Date of Grant, the Employee’s employment or service with the Company terminates for any reason other than Cause after attainment of age 59  ¹/₂ and 4 years of service (“Normal Retirement”), the Employee’s service shall be deemed to have terminated on the fourth anniversary of the Date of Grant so that the Employee’s Restricted Stock Units shall be deemed to become fully vested on such date.

(e) Notwithstanding any provision in Section 3(b), 3(c), or 3(d) above to the contrary, if on December 31^st before the applicable anniversary of the Date of Grant described in Section 3(b) above, the Company’s Common Equity Tier 1 Risk-Based Capital Ratio (“CET 1”) is less than the greater of (i) the CET 1 goal set forth in the Company’s Capital Management Policy or (ii) the required minimum CET 1 established by the Federal Reserve, the Employee’s Restricted Stock Units that otherwise would have vested upon satisfaction of the applicable service-based vesting requirements described above shall instead vest on the date that the Committee certifies that the Company’s CET1 is greater than or equal to the applicable goal described in (i) or (ii) above (which shall be no later than March 15^th of the year after the year in which such CET 1 goal is achieved). However, if the Company’s CET 1 remains less than the applicable goal described in (i) and (ii) above on the December 31^st of each of the two consecutive years after the otherwise applicable vesting date described in Section 3(b), 3(c), or 3(d) (as applicable) above, the Employee shall not vest in that 1/2 share of the Restricted Stock Units and shall instead forfeit such Restricted Stock Units.

(a) To the extent the Employee fails to satisfy the vesting conditions of Section 3 of this Agreement, the Employee’s RSUs shall be forfeited.

(b) Notwithstanding any provision of this Agreement to the contrary, the Committee may cause the Employee to forfeit all unvested RSUs and require repayment of any amount previously paid under this Agreement in accordance with the terms of the Huntington

Huntington Bancshares Incorporated

Restricted Stock Unit Grant Agreement

Bancshares Incorporated Recoupment/Clawback Policy (“the Policy”), any other applicable policy of the Company, and any other applicable laws and regulations. The Policy is available on the Risk Management and Corporate Policy home page of the Huntington intranet.

(c) Notwithstanding anything herein to the contrary, in the event that the Employee’s employment is terminated for Cause, the Employee shall forfeit any RSUs that were not previously vested before the date of termination.

(d) This RSU grant is subject to acceptance of all the terms, conditions and limitations of the Plan. The Plan may be amended from time to time, including but not limited to provisions on tax withholding and forfeiture. This RSU grant is subject to such rules and regulations that the Committee may adopt for administration of the Plan, and to all applicable laws, rules and regulations, and to such approvals by any governmental agencies or national securities exchanges as may be required. By executing this Agreement, the Employee acknowledges that the joint service and performance-based vesting requirements under this Agreement are consistent with the vesting requirements for RSUs granted under the prior year’s agreements with a date of grant of May 1, 2014.

Notwithstanding any provision to the contrary, upon the occurrence of a Change in Control, the Employee shall become immediately vested in 100% of the Restricted Stock Units in the Employee’s RSU Account if:

(a) within 12 months after a Change in Control occurs, the Employee’s service has been terminated by the Company (provided that such termination is for a reason other than for Cause); or

(b) the Company previously terminated the Employee’s service without Cause (i) during the year before the Change in Control was consummated but (ii) after a third party or the Company had taken steps reasonably calculated to effect a Change in Control. In addition to items (i)-(ii) above, the Employee also must reasonably demonstrate that such termination of service was in connection with or in anticipation of the Change in Control.

The Company, or its transfer agent, will convert the Restricted Stock Units in the Employee’s RSU Account into Shares and deliver the total number of Shares due to the Employee within 60 days after the date the Restricted Stock Units vest or as soon as administratively possible after such date, except as otherwise provided in Section 13 below. However, notwithstanding any provision to the contrary, if, in the reasonable determination of the Company, an Employee is a “specified employee” for purposes of Section 409A of the Internal Revenue Code of 1986, as amended, and the guidance promulgated thereunder (“Code

Huntington Bancshares Incorporated

Restricted Stock Unit Grant Agreement

Section 409A”), then, if necessary to avoid the imposition on the Employee of excise tax and interest under Code Section 409A, the Company shall not deliver the Shares otherwise payable upon the Employee’s termination and separation of service until the date that is 30 days after 6 months following the Employee’s termination and separation of service from the Company. The delivery of the Shares shall be subject to payment of the applicable withholding tax liability as set forth in Section 8. If the Employee dies before the Company has distributed any portion of the vested Restricted Stock Units, the Company will transfer any Shares payable with respect to the vested Restricted Stock Units in accordance with the Employee’s written beneficiary designation or to the Employee’s estate if no written beneficiary designation is provided. If the Employee did not have a will, any Shares payable with respect to the vested Restricted Stock Units will be distributed in accordance with the laws of descent and distribution.

If the Employee is eligible to participate in the Huntington Bancshares Incorporated Executive Deferred Compensation Plan, or any successor thereto (the “Deferred Compensation Plan”), the Employee may defer the receipt of Shares relating to the RSUs beyond the date the Shares otherwise would be payable under this Agreement and under the rules and procedures established by the Company under the Deferred Compensation Plan. The Employee’s election to defer receipt of such Shares shall be made on a form provided by the Company, which shall specify the amount of Shares to be deferred and the distribution date for such Shares. The Employee may elect to defer receipt of such Shares until the earlier of: (i) the date of the Employee’s Separation from Service, (ii) the date of the Employee’s retirement (as defined under the Deferred Compensation Plan), or (iii) the Employee’s specified date of payment. Elections to defer will become irrevocable in accordance with the terms of the Deferred Compensation Plan and with Code Section 409A. Notwithstanding anything to the contrary in this Agreement, Shares will not be issued and the Employee shall have no voting rights of a stockholder in the Company to the extent that the Employee has elected to defer the issuance and receipt of such Shares; provided, however, that the Employee shall continue to receive dividend equivalent credits during the period of deferral credited to the RSU Account at such times as provided in this Agreement.

The Company shall have the power and the right to deduct or withhold, or require the Employee to remit to the Company, an amount sufficient to satisfy federal, state, and local taxes, domestic or foreign, required by law or regulation to be withheld with respect to any taxable event arising as a result of this Agreement. Tax and any other necessary withholding obligations shall be satisfied in a manner consistent with Article 19 of the Plan.

Huntington Bancshares Incorporated

Restricted Stock Unit Grant Agreement

During any Period(s) of Restriction, the Employee shall have no right to transfer, sell, pledge, assign, or hypothecate, other than by will or the laws of descent and distribution, any rights with respect to the Employee’s Award of RSUs. No RSU shall be subject to execution, attachment, or similar process.

The right of the Employee or his or her beneficiary to receive a distribution hereunder shall be an unsecured claim against the general assets of the Company, and neither the Employee nor his or her beneficiary shall have any rights in or against any amounts credited to the Employee’s RSU Account or any other specific assets of the Company. All amounts credited to the Employee’s RSU Account shall constitute general assets of the Company and may be disposed of by the Company at such time and for such purposes, as it may deem appropriate.

Until the Restricted Stock Units have vested and Shares have been issued, Employee shall not have any voting rights as a stockholder of the Company with respect to the Restricted Stock Units.

To the extent that cash dividends are paid on Shares after the Date of Grant and before the date the Employee receives the Shares subject to this Grant, the Employee’s RSU Account will be credited with an additional number of Restricted Stock Units to reflect reinvested dividend equivalents with respect to the period of time between the Date of Grant and the delivery of Shares under this Agreement. Such dividend equivalent credits will be equal in value (based on the reported dividend rate on the date dividends were paid) to the amount of dividends paid on the Shares represented by the Restricted Stock Units in the Employee’s RSU Account. The Employee’s RSU account will be credited with whole and fractional RSUs equal to the dollar amount of the reinvested dividend equivalents based on the Fair Market Value on the dividend payment dates. The Employee shall vest in the additional Restricted Stock Units in accordance with Section 3 of the Agreement in the same manner that the Employee vests in the original grant of Restricted Stock Units held in the RSU Account. These additional Restricted Stock Units will be distributed in whole Shares in accordance with Section 6 of this Agreement, with the value of any remaining fractional Shares distributed in cash.

Huntington Bancshares Incorporated

Restricted Stock Unit Grant Agreement

In the event of a stock split, stock dividend, spin off, merger, or other event described in Section 4.3 of the Plan, the number of Restricted Stock Units in the Employee’s RSU Account shall be adjusted in accordance with the provisions of Section 4.3 of the Plan.

The delivery of all or any of the Shares shall only be effective at such time that the issuance of such Shares will not violate any state or federal securities or other laws. The Company is under no obligation to effect any registration of Shares under the Securities Act of 1933 or to effect any state registration or qualification of the Shares. The Company may, in its sole discretion, delay the delivery of the Shares or place restrictive legends on such Shares in order to ensure that the issuance of any Shares will be in compliance with federal or state securities laws and the rules of the NASDAQ Global Select or any other exchange upon which the Company’s common stock is traded. If the Company delays the delivery of the Shares in order to ensure compliance with any state or federal securities or other laws, the Company shall deliver the Shares at the earliest date at which the Company reasonably believes that such delivery will not cause such violation, or at such other date that may be permitted under Code Section 409A.

The Grant is subject to acceptance of all the terms, conditions and limitations of the Plan, including Article 20 with respect to forfeitures. The Plan may be amended from time to time, including but not limited to provisions on tax withholding and forfeiture. This Grant is subject to such rules and regulations that the Committee may adopt for administration of the Plan, and to all applicable laws, rules and regulations, and to such approvals by any governmental agencies or national securities exchanges as may be required. In the event of a conflict between one or more provisions of this Agreement and one or more provisions of the Plan, the provisions of the Plan shall govern. A copy of the Plan is available upon request by contacting the Human Resources Department at the Company’s executive offices.

The Employee understands and agrees that this Agreement does not impact in any way the right of the Company to terminate or change the terms of the employment of Employee at any time for any reason whatsoever, with or without Cause, nor confer upon any right to continue in the employ of the Company.
