WITNESSETH WHEREAS, the Amended and Restated Humana Inc. Stock Incentive Plan (the "Plan"), was approved by the Company’s Board of Directors and stockholders; and WHEREAS, the Company desires to grant to Optionee an option to purchase shares of common stock of the Company in accordance with the Plan; NOW, THEREFORE, in consideration of the premises and mutual covenants hereinafter set forth, and other good and valuable consideration, the Company and Optionee agree as follows: I. OPTION GRANT A. Grant of Option. The Company hereby grants to Optionee, as a matter of separate inducement and agreement and not in lieu of salary or other compensation for services, an Incentive Stock Option to purchase <shares_awarded> shares of the $.16-2/3 par value common stock of the Company ("Common Stock") at the purchase price of $<award_price> per share (the "Option") exercisable on the terms and conditions set forth herein. B. Term. The term of the Option shall commence upon the Date of Grant, and shall expire on <expire_Date> (the “Expiration Date”). C. Vesting of Option. Except as otherwise set forth herein, the Option shall be exercisable by Optionee or his/her personal representative on and after the first anniversary of the Date of Grant in cumulative annual installments of one-third of the number of Shares covered hereby. D. Effect of Termination of Employment on Option. If the employment of Optionee by the Company is terminated for Cause, all the rights of Optionee under this Agreement, whether or not exercisable, shall terminate immediately. If the employment of Optionee is terminated for any reason other than for Cause, the Option shall vest and remain exercisable in accordance with Sections 12 and 13 of the Plan, but in no event beyond the Expiration Date. E. Exercise of Option. 1. The Option shall be exercisable only by written notice to the Secretary of the Company at the Company's principal executive offices, or through the online procedure to such broker- dealer as designated by the Company, Optionee or his/her legal representative as herein provided. Such

notice shall state the number of Shares with respect to which the Option is being exercised and shall be signed, or authorized electronically, by Optionee or his/her legal representative, as applicable. 2. The purchase price shall be paid as follows: a) In full in cash upon the exercise of the Option; b) By tendering to the Company Shares owned by Optionee prior to the date of exercise and having an aggregate Fair Market Value equal to the cash exercise price applicable to the Option; or c) A combination of I.E.(2)(a) and I.E.(2)(b) above. 3. Federal, state and local income and employment taxes and other amounts as may be required by law to be collected by the Company (“Withholding Taxes”) in connection with the exercise of the Option shall be paid pursuant to the Plan by Optionee prior to the delivery of any Common Stock under this Agreement. The Company shall, at Optionee’s election, withhold delivery of a number of Shares with a Fair Market Value as of the exercise date equal to the Withholding Taxes in satisfaction of Optionee’s obligations hereunder. II. AGREEMENT NOT TO COMPETE AND AGREEMENT NOT TO SOLICIT. Optionee agrees and understands that the Company’s business is a profit-generating business operating in a highly competitive business environment and that the Company has a legitimate business interest in, among other things, its confidential information and trade secrets (including as protected in other agreements and policies between the Company and Optionee) that it is providing Optionee, and in the significant time, money, training, team building and other efforts it expends to develop Optionee’s skills to assist in performing Optionee’s duties for the Company, including with respect to establishing, developing and maintaining the goodwill and business relationships with Protected Relationships (defined below) and employees, each of which Optionee agrees are valuable assets of the Company to which it has devoted substantial resources. Optionee acknowledges that the grant Optionee is receiving under the Plan is a meaningful way that the Company entrusts Optionee with its goodwill and aligns Optionee with the Company objective of increasing the value of the Company’s business. Accordingly, Optionee acknowledges the importance of protecting the value of the Company’s business through, among other things, covenants to restrict Optionee from engaging in activities that would adversely affect the value of the Company and its goodwill. A. Agreement Not to Compete. Optionee agrees that during the Restricted Period (defined below) and within the Restricted Geographic Area (defined below), Optionee will not, directly or indirectly, perform the same or similar responsibilities Optionee performed for the Company in connection with a Competitive Product or Service (defined below). Notwithstanding the foregoing, Optionee may accept employment with a Competitor (defined below) whose business is diversified, provided that: (1) Optionee will not be engaged in working on or providing Competitive Products or Services, or otherwise use or disclose the Company’s confidential information or trade secrets; and (2) the Company receives written - 2 -

assurances from the Competitor and Optionee that are satisfactory to the Company that Optionee will not work on or provide Competitive Products or Services, or otherwise use or disclose confidential information or trade secrets. In addition, nothing in this Agreement is intended to prevent Optionee from investing Optionee’s funds in securities of a person engaged in a business that is directly competitive with the Company if the securities of such a person are listed for trading on a registered securities exchange or actively traded in an over-the-counter market and Optionee’s holdings represent less than one percent (1%) of the total number of outstanding shares or principal amount of the securities of such a person. B. Agreement Not to Solicit Protected Relationships. During the Restricted Period and in connection with a Competitive Product or Service, Optionee shall not, individually or jointly with others, directly or indirectly: (1) solicit or attempt to solicit any Protected Relationships (defined below); or (2) induce or encourage any Protected Relationships to terminate a relationship with the Company or to otherwise cease to accept services or products from the Company. C. Agreement Not to Solicit Employees. During the Restricted Period, Optionee shall not, individually or jointly with others, directly or indirectly: (1) or by assisting others, solicit, recruit, hire, or encourage (or attempt to solicit, recruit, hire or encourage), any Company employees or former employees with whom Optionee worked, had business contact, or about whom Optionee gained non- public or confidential information (“Employees or Former Employees”); (2) contact or communicate with Employees or Former Employees for the purpose of inducing, assisting, encouraging and/or facilitating them to terminate their employment with the Company or find employment or work with another person or entity; (3) provide or pass along to any person or entity the name, contact and/or background information about any Employees or Former Employees or provide references or any other information about them; (4) provide or pass along to Employees or Former Employees any information regarding potential jobs or entities or persons to work for, including but not limited to job openings, job postings, or the names or contact information of individuals or companies hiring people or accepting job applications; and/or (5) offer employment or work to any Employees or Former Employees. For purposes of this covenant, “Former Employees” shall refer to employees who are not employed by the Company at the time of the attempted recruiting or hiring, but were employed by, or working for the Company in the three (3) months prior to the time of the attempted recruiting or hiring and/or interference. D. Effect of Termination of Employment other than a Change in Control Termination on Agreements Not to Compete and Not to Solicit. 1. In the event Optionee voluntarily resigns or is discharged by the Company with Cause at any time prior to the vesting of the Option, the prohibitions on Optionee set forth in Sections II.A, II.B and II.C shall remain in full force and effect. 2. In the event Optionee is discharged by the Company other than with Cause, including in connection with a Workforce Reduction or Position Elimination, or certain divestiture related terminations, prior to the vesting of the Option, the prohibitions set forth in Section II.A shall remain in full - 3 -

force and effect during the period of time following Optionee’s termination equal to the lesser of (x) the Restricted Period or (y) the period of time during which Optionee is deemed to be entitled to severance measured by the sum of (i) the number of weeks Optionee is entitled to severance under the Company’s applicable severance policy, plus (ii) a number of weeks equal to (A) the value of the acceleration or continuation of the vesting of any Options as a result of Optionee’s termination under this Agreement or the Plan that would otherwise have been forfeited, with such value measured by multiplying the number of Shares underlying the Options that vested as a result of the termination of employment by the difference of the per Share Fair Market Value on the Last Day minus the applicable per Share exercise price, divided by (B) Optionee’s then-current weekly base salary, plus (iii) any additional period that the Company determines to provide severance to Optionee, in its discretion. 3. In the event Optionee is discharged by Company other than with Cause prior to vesting herein of the Option, the prohibitions set forth in Sections II.B and II.C above shall remain in full force and effect. 4. After the vesting of the Option, the prohibitions on Optionee set forth herein shall remain in full force and effect, except as otherwise provided in Section II.E. E. Effect of a Change in Control Termination on Agreements Not to Compete and Not to Solicit. 1. Notwithstanding anything set forth in Section II.D., in the event of a Change in Control Termination (defined below), the prohibitions on Optionee set forth in Section II.A shall remain in full force and effect only if the acquirer or successor to the Company following the Change in Control shall, solely at its option, pay, within thirty (30) days following Optionee's employment termination date with the Company or its successor, to Optionee the Non-Compete Payment. Notwithstanding any previous agreement between Optionee and the Company relating to the prohibitions set forth in Section II.A, the “Non-Compete Payment” shall be an amount at least equal to Optionee’s then current annual base salary. Such amount shall be in addition to any other amounts paid or payable to Optionee with respect to other severance plans or policies maintained by the Company. For the avoidance of doubt, the provisions of this Section II.E shall supersede any agreement between Optionee and the Company relating to the prohibitions on Optionee set forth in Section II.A, with the exception of any similar agreement contained in (i) any employment agreement between Optionee and the Company, (ii) any agreement between Optionee and the Company not related to the employment of Optionee by the Company, (iii) any severance plan or policy of the Company and (iv) any change in control severance plan or policy of the Company. 2. In the event of a Change in Control Termination, the prohibitions on Optionee set forth in Sections II.B. and II C. shall remain in full force and effect. F. Governing Law. Notwithstanding any other provision herein to the contrary, the provisions of this Section II of the Agreement shall be governed by, and construed in accordance with, the laws of the Commonwealth of Kentucky without regard to its conflicts or choice of laws rules or principles - 4 -

that might otherwise refer construction or interpretation of this Section II to the substantive law of another jurisdiction. G. Injunctive Relief; Invalidity of Any Provision. Optionee acknowledges that (1) his or her services to the Company are of a special, unique and extraordinary character, (2) his or her position with the Company will place him or her in a position of confidence and trust with respect to the operations of the Company, (3) he or she will benefit from continued employment with the Company, (4) the nature and periods of restrictions imposed by the covenants contained in this Section II are fair, reasonable and necessary to protect the Company, (5) the Company would sustain immediate and irreparable loss and damage if Optionee were to breach any of such covenants, and (6) the Company’s remedy at law for such a breach will be inadequate. Accordingly, Optionee agrees and consents that the Company, in addition to the recovery of damages and all other remedies available to it, at law or in equity, shall be entitled to seek both preliminary and permanent injunctions to prevent and/or halt a breach or threatened breach by Optionee of any covenant contained in Section II hereof. If any provision of this Section II is determined by a court of competent jurisdiction to be invalid in whole or in part, it shall be deemed to have been amended, whether as to time, area covered or otherwise, as and to the extent required for its validity under applicable law, and as so amended, shall be enforceable. The parties further agree to execute all documents necessary to evidence such amendment. III. MISCELLANEOUS PROVISIONS A. Binding Effect & Adjustment. This Agreement shall be binding and conclusive upon each successor and assign of the Company. Optionee’s obligations hereunder shall not be assignable to any other person or entity. It is the intent of the parties to this Agreement that the benefits of any appreciation of the underlying Common Stock during the term of the Award shall be preserved in any event, including but not limited to a recapitalization, merger, consolidation, reorganization, stock dividend, stock split, reverse stock split, spin-off or similar transaction, or other change in corporate structure affecting the Shares, as more fully described in Sections 4.6 and 11 of the Plan. All obligations imposed upon Optionee and all rights granted to Optionee and to the Company shall be binding upon Optionee's heirs and legal representatives. B. Amendment.

D. Jurisdiction; Service of Process. Any action or proceeding seeking to enforce any provision of, or based on any right arising out of, this Agreement may be brought against any of the parties in the courts of the Commonwealth of Kentucky, County of Jefferson, or, if it has or can acquire jurisdiction, in the United States District Court for the Western District of Kentucky, and each of the parties consents to the jurisdiction of such courts (and of the appropriate appellate courts) in any such action or proceeding and waives any objection to venue laid therein. Process in any action or proceeding referred to in the preceding sentence may be served on any party anywhere in the world. E. No Employment Agreement. Nothing herein confers on Optionee any rights with respect to the continuance of employment or other service with the Company, nor will it interfere with any right the Company would otherwise have to terminate or modify the terms of Optionee's employment or other service at any time. F. Severability. If any provision of this Agreement is or becomes or is deemed invalid, illegal or unenforceable in any relevant jurisdiction, or would disqualify this Award under any law deemed applicable by the Committee, such provision shall be construed or deemed amended to conform to applicable laws or if it cannot be construed or deemed amended without, in the determination of the Committee, materially altering the intent of the Plan, it shall be stricken and the remainder of the Agreement shall remain in full force and effect. Any provision in this Agreement determined by competent authority to be in conflict with 422 of the Internal Revenue Code of 1986, as amended, or its successor, in regard to qualifying this Option as an incentive stock option shall be ineffective ab initio to the extent of such conflict. G. Assignment. The Option granted under this Agreement to Optionee may not be assigned, transferred, pledged, alienated or hypothecated in any manner during Optionee's lifetime, but shall be solely and exclusively the right of Optionee to exercise during his/her lifetime. Should Optionee attempt to assign, transfer, pledge, alienate or hypothecate the Option or any rights hereunder in any manner whatsoever, such action shall constitute a breach of the covenants hereunder and the Company may terminate the Option as to any then unexercised shares. H. Defined Terms. 1. Any term used herein and not otherwise defined herein shall have the same meaning as in the Plan. Any conflict between this Agreement and the Plan will be resolved in favor of the Plan. Any disputes or questions of right or obligation which shall result from or relate to any interpretation of this Agreement shall be determined by the Committee.
