EXHIBIT 10.1

NATIONAL INTERSTATE CORPORATION

LONG TERM INCENTIVE PLAN

(As Amended through March 1, 2013)

1. Purpose of the Plan. The purpose of this Plan is to attract, retain and motivate directors, consultants, officers and other key employees of National Interstate Corporation (the “Company”) and its Subsidiaries and to provide to such persons incentives and rewards for superior performance and contribution. The Company previously adopted the 1998 National Interstate Corporation Stock Option Plan, as amended (the “Prior Plan”). The Company amended and restated the Prior Plan as the National Interstate Corporation Long Term Incentive Plan, as of August 5, 2004 (the “Effective Date”), with the October 18, 2004 approval of the Company’s shareholders. At that time, the Plan replaced and superseded the Prior Plan, provided that awards granted thereunder prior to the Effective Date continued in accordance with their terms. The Plan was amended effective March 16, 2009, to comply with the performance-based compensation exception to Section 162(m) of the Internal Revenue Code of 1986, as amended. The Company’s Board of Directors, has approved an amendment to the Plan to be effective March 1, 2013, subject to shareholder approval, to increase to the number of shares available for issuance under the Plan by 500,000.

The Committee shall make or provide for such adjustments in the numbers of Common Shares covered by outstanding Option Rights, Appreciation Rights, Performance Shares, Deferred Shares and share-based awards described in Section 10 of the Plan granted hereunder, in the Option Price and Base Price provided in outstanding Appreciation Rights, and in the kind of shares covered thereby, as the Committee, in its sole discretion, exercised in good faith, may determine is equitably required to prevent dilution or enlargement of the rights of Participants or Optionees that otherwise would result from (a) any stock dividend, stock split, combination of shares, recapitalization or other change in the capital structure of the Company, including the share split that is contemplated to be effective prior to the Company’s proposed initial public offering (if any), or (b) any merger, consolidation, spin-off, split-off, spin-out, split-up, reorganization, partial or complete liquidation or other distribution of assets (including, without limitation, a special or large non-recurring dividend), issuance of rights or warrants to purchase securities, or (c) any other corporate transaction or event having an effect similar to any of the foregoing. Moreover, in the event of any such transaction or event, the Committee, in its discretion, may provide in substitution for any or all outstanding awards under this Plan such alternative consideration as it, in good faith, may determine to be equitable in the circumstances and may require in connection therewith the surrender of all awards so replaced. The Committee may also make or provide for such adjustments in the numbers of shares specified in Section 3 of this Plan as the Committee in its sole discretion, exercised in good faith, may determine is appropriate to reflect any transaction or event described in this Section 12; provided, however, that any such adjustment to the number specified in Section 3(c)(i) shall be made only if and to the extent that such adjustment would not cause any Option intended to qualify as an Incentive Stock Option to fail so to qualify. In no event shall any adjustment be required under this Section 12 if the Committee determines that such action could cause an award to fail to satisfy the conditions of an applicable exception from the requirements of Section 409A of the Code or otherwise could subject a Participant to the additional tax imposed under Section 409A in respect of an outstanding award.

13. Fractional Shares. The Company shall not be required to issue any fractional Common Shares pursuant to this Plan. The Committee may provide for the elimination of fractions or for the settlement of fractions in cash.

14. Withholding Taxes. The Company shall have the right to deduct from any payment under this Plan an amount equal to the federal, state, local, foreign and other taxes which in the opinion of the Company are required to be withheld by it with respect to such payment and to the extent that the amounts available to the Company for such withholding are insufficient, it shall be a condition to the receipt of such payment or the realization of such benefit that the Participant or such other person make arrangements satisfactory to the Company for payment of the balance of such taxes required to be withheld. At the discretion of the Committee, such arrangements may include relinquishment of a portion of such benefit pursuant to procedures adopted by the Committee from time to time.

15. Foreign Employees. In order to facilitate the making of any grant or combination of grants under this Plan, the Committee may provide for such special terms for awards to Participants who are foreign nationals or who

are employed by the Company or any Subsidiary outside of the United States of America as the Committee may consider necessary or appropriate to accommodate differences in local law, tax policy or custom. Moreover, the Committee may approve such supplements to or amendments, restatements or alternative versions of this Plan as it may consider necessary or appropriate for such purposes, without thereby affecting the terms of this Plan as in effect for any other purpose, and the Corporate Secretary or other appropriate officer of the Company may certify any such document as having been approved and adopted in the same manner as this Plan. No such special terms, supplements, amendments or restatements, however, shall include any provisions that are inconsistent with the terms of this Plan as then in effect unless this Plan could have been amended to eliminate such inconsistency without further approval by the stockholders of the Company.

16. Administration of the Plan.

a. This Plan shall be administered by the Compensation Committee of the Board. A majority of the Committee shall constitute a quorum, and the action of the members of the Committee present at any meeting at which a quorum is present, or acts unanimously approved in writing, shall be the acts of the Committee. The Board may perform any function of the Committee hereunder, and the Board shall perform all functions of the Committee with respect to any award for a Non-Employee Director, in which case the term “Committee” shall refer to the Board.

b. The interpretation and construction by the Committee of any provision of this Plan or of any agreement, notification or document evidencing the grant of Option Rights, Appreciation Rights, Restricted Shares, Deferred Shares, Performance Units, Performance Shares or any awards granted under Section 10 of the Plan and any determination by the Committee pursuant to any provision of this Plan or of any such agreement, notification or document shall be final and conclusive. No member of the Committee shall be liable for any such action or determination made in good faith.

17. Amendments and Other Matters.

a. The Board may at any time and from time to time amend the Plan in whole or in part; provided, however, that any amendment which must be approved by the stockholders of the Company in order to comply with applicable law or the rules of the Nasdaq National Market System or, if the Common Shares are not traded on the Nasdaq National Market System, the principal national securities exchange upon which the Common Shares are traded or quoted, shall not be effective unless and until such approval has been obtained. Presentation of this Plan or any amendment thereof for stockholder approval shall not be construed to limit the Company’s authority to offer similar or dissimilar benefits under other plans or otherwise with or without stockholder approval. Without limiting the generality of the foregoing, the Board of Directors may amend this Plan to eliminate provisions which are no longer necessary as a result in changes in tax or securities laws or regulations, or in the interpretation thereof.

b. Except as otherwise expressly provided in Section 19 hereof, the Committee shall not, without the further approval of the stockholders of the Company, authorize the amendment of any outstanding Option Right or Appreciation Right to reduce the Option Price or Base Price. Furthermore, no Option Right or Appreciation Right shall be cancelled and replaced with awards having a lower Option Price or Base Price, respectively, without further approval of the stockholders of the Company. This Section 17(b) is intended to prohibit the repricing of “underwater” Option Rights and Appreciation Rights and shall not be construed to prohibit the adjustments provided for in Section 12 of this Plan.

c. The Committee also may permit Participants to elect to defer the issuance of Common Shares or the settlement of awards in cash under the Plan pursuant to such rules, procedures or programs as it may establish for purposes of this Plan. The Committee also may provide that deferred issuances and settlements include the payment or crediting of dividend equivalents or interest on the deferral amounts.

d. The Committee may condition the grant of any award or combination of awards authorized under this Plan on the deferral by the Participant of his or her right to receive a cash bonus or other compensation otherwise payable by the Company or a Subsidiary to the Participant.

e. In case of a Change in Control of the Company, or in the case of a termination of employment of a Participant by reason of death, disability or normal or early retirement, or in the case of hardship of a Participant or other special circumstances, the Committee may, in its sole discretion, accelerate the time at which any Option Right or Appreciation Right may be exercised or the time when a Performance Unit or Performance Share shall be deemed to have been fully earned or the time when a substantial risk of forfeiture or prohibition on transfer of Restricted Shares shall lapse or the time when a Deferral Period shall end. In addition, the Committee may, in its sole discretion, modify any Option Right or Appreciation Right to extend the period following termination of a Participant’s employment to the Company or any Subsidiary during which such award will remain outstanding and be exercisable, provided that no such extension shall result in any award being exercisable more than ten years after the Date of Grant.

f. This Plan shall not confer upon any Participant any right with respect to continuance of employment or other service with the Company or any Subsidiary, nor shall it interfere in any way with any right the Company or any Subsidiary would otherwise have to terminate such Participant’s employment or other service at any time.

g. To the extent that any provision of this Plan would prevent any Option Right that was intended to qualify as an Incentive Stock Option from qualifying as such, that provision shall be null and void with respect to such Option Right. Such provision, however, shall remain in effect for other Option Rights and there shall be no further effect on any provision of this Plan.

h. Subject to Section 20, this Plan shall continue in effect until the date on which all Common Shares available for issuance or transfer under this Plan have been issued or transferred and the Company has no further obligation hereunder.

i. Neither a Participant nor any other person shall, by reason of participation in the Plan, acquire any right or title to any assets, funds or property of the Company or any Subsidiary, including without limitation, any specific funds, assets or other property which the Company or any Subsidiary may set aside in anticipation of any liability under the Plan. A Participant shall have only a contractual right to an award or the amounts, if any, payable under the Plan, unsecured by any assets of the Company or any Subsidiary, and nothing contained in the Plan shall constitute a guarantee that the assets of the Company or any Subsidiary shall be sufficient to pay any benefits to any person.

j. This Plan and each Evidence of Award shall be governed by the laws of the State of Ohio, excluding any conflicts or choice of law rule or principle that might otherwise refer construction or interpretation of the Plan to the substantive law of another jurisdiction.

k. If any provision of the Plan is or becomes invalid, illegal or unenforceable in any jurisdiction, or would disqualify the Plan or any award under any law deemed applicable by the Committee, such provision shall be construed or deemed amended or limited in scope to conform to applicable laws or, in the discretion of the Committee, it shall be stricken and the remainder of the Plan shall remain in full force and effect.

18. Applicable Laws. The obligations of the Company with respect to awards under the Plan shall be subject to all Applicable Laws and such approvals by any governmental agencies as the Committee determines may be required.

19. Prior Plan. Option Rights and dividend equivalents granted prior to the Effective Date under the Prior Plan shall be subject to the limitations contained in the following provisions:

a. Unless and until forfeited, cancelled or terminated, and except as otherwise provided in this Section 19, each Option Right will become exercisable to the extent of one-fifth of the Common Shares specified in the Evidence of Award on December 31 of the year in which occurs the Date of Grant and on each of the first four anniversaries of such December 31. A Participant’s Option Rights shall be forfeited (to the extent they have not become exercisable pursuant to the preceding sentence), if he or she ceases to be continuously employed by the Company and its Subsidiaries for any reason.

b. A Participant’s Option Rights and related dividend equivalents will terminate on the earliest of the following dates: (i) sixty days following the date of the Participant’s termination of employment with the Company and its Subsidiaries for any reason; or (ii) ten years from the Date of Grant. Any dividend equivalents also shall terminate upon the exercise, forfeiture or cancellation of the related Option Rights.

c. Any dividend equivalents shall be credited against the Option Price with respect to unvested Option Rights and shall be paid in cash with respect to vested Option Rights.

d. Notwithstanding anything contained in this Plan to the contrary: (i) with respect to Option Rights granted under the Prior Plan before January 1, 2004, the Company, in its sole discretion, may at any time require Participants to exercise all vested Option Rights, all unvested Option Rights, or both, and the Option Price of such Option Rights shall be reduced by 25%; and (ii) with respect to Option Rights granted under the Prior Plan on or after January 1, 2004, the Company, in its sole discretion, may at any time require Participants to exercise all vested Option Rights (without a reduction in the Option Price) and forfeit all unvested Option Rights.

20. Termination. No grant shall be made under this Plan more than 10 years after the date on which this amended Plan is approved by the Board of Directors of the Company, but all grants effective on or prior to such date shall continue in effect thereafter subject to the terms thereof and of this Plan.

21. Compliance with Section 409A of the Code. Awards granted under this Plan shall be designed and administered in such a manner that they are either exempt from the application of, or comply with, the requirements of Section 409A of the Code. To the extent that the Committee determines that any award granted under the Plan is subject to Section 409A of the Code, the Evidence of Award shall incorporate the terms and conditions necessary to avoid the imposition of an additional tax under Section 409A of the Code upon a Participant. Notwithstanding any other provision of the Plan or any Evidence of Award (unless the Evidence of Award provides otherwise with specific reference to this Section), an award shall not be granted, deferred, accelerated, extended, paid out, settled, substituted or modified under this Plan in a manner that would result in the imposition of an additional tax under Section 409A of the Code upon a Participant. Although the Company intends to administer the Plan so that awards will be exempt from, or will comply with, the requirements of Section 409A of the Code, the Company does not warrant that any award under the Plan will qualify for favorable tax treatment under Section 409A of the Code or any other provision of federal, state, local, or non-United States law. Neither the Company, its Subsidiaries, nor their respective directors, officers, employees or advisers shall be liable to any Participant (or any other individual claiming a benefit through the Participant) for any tax, interest, or penalties the Participant might owe as a result of the grant, holding, vesting, exercise, or payment of any award under the Plan. Any reference in this Plan to Section 409A of the Code will also include the applicable proposed, temporary or final regulations, or any other guidance, issued with respect to such Section by the U.S. Department of the Treasury or the Internal Revenue Service.
