Amended 2005 Director Stock Option Plan

 Exhibit 10.2 
  
 AMERICAN DENTAL PARTNERS, INC. 
  
 2005 DIRECTORS STOCK OPTION PLAN 
  
 Amended as of July 13, 2005 
  
 Section 1. Purpose of Plan. 
  
 The purpose of this 2005 Directors Stock Option Plan (the “Plan”) of American Dental Partners, Inc., a Delaware corporation (the
“Company”), is to advance the interests of the Company and its stockholders by providing Eligible Directors (as defined in Section 3, below) with an opportunity to participate in the Company’s future prosperity and growth and an
incentive to increase the value of the Company based on the Company’s performance, development, and financial success. These objectives will be promoted by granting to Eligible Directors options (the “Options”), which are not intended
to qualify as incentive stock options under Section 422 of the Internal Revenue Code of 1986, as amended (the “Code”), to purchase shares of the Company’s common stock, $.01 par value (the “Shares”). 
  
 Section 2. Administration of Plan. 
  
 The Plan shall be administered by a committee (the “Committee”) of
one or more directors. The member or members of the Committee shall serve at the pleasure of the Company’s board of directors (the “Board”), which may remove members from the Committee or appoint new members to the Committee from time
to time, and members of the Committee may resign by written notice to the Chairman of the Board or the Secretary of the Company. The Committee shall have the power and authority to: (a) approve the grant of Options to Eligible Directors (such
Eligible Directors, “Participants”); (b) approve the terms and conditions, not inconsistent with the terms hereof, of any Option, including without limitation time and performance restrictions, and approve the form of Stock Option
Agreement (as defined in Section 5, below); (c) adopt, alter, and repeal such administrative rules, guidelines, and practices governing the Plan as it shall, from time to time, deem advisable; (d) interpret the terms and provisions of the Plan and
any Option granted and any agreements relating thereto; and (e) take any other actions the Committee considers appropriate in connection with, and otherwise supervise the administration of, the Plan, all in a manner consistent with the other
provisions of the Plan. All decisions made by the Committee pursuant to the provisions hereof shall be made in the Committee’s sole discretion and shall be final and binding on all persons. 
  
 Section 3. Participants in Plan. 
  
 The persons eligible to receive Options under the Plan shall be those
directors of the Company who are not employees or officers of the Company or any subsidiary of the Company (“Eligible Directors”). 

 Section 4. Shares Subject to Plan. 
  
 The maximum aggregate number of Shares which may be issued under the Plan shall be 150,000 Shares. The Shares that may be
issued under the Plan may be authorized but unissued Shares or issued Shares reacquired by the Company, including without limitation Shares purchased on the open market, and held as treasury shares. 
  
 If any Shares that have previously been the subject of an Option cease to be
the subject of an Option (other than by reason of exercise), or if any Shares previously distributed under the Plan are returned to the Company in connection with the exercise of an Option (including without limitation in payment of the exercise
price or tax withholding), such Shares shall again be available for distribution in connection with future grants under the Plan. 
  
 Section 5. Grant of Options. 
  
 Each Option granted under the Plan shall be authorized by the Committee and shall be evidenced by a written agreement (the “Stock Option
Agreement”) in form approved by the Committee from time to time, which shall be dated as of the date on which the Option is granted, signed by an officer of the Company authorized by the Committee, and signed by the Participant, and which shall
describe the Option and state that the Option is subject to all the terms and provisions of the Plan and such other terms and provisions, not inconsistent with the Plan, as the Committee may approve. The date on which the Committee approves the
granting of an Option shall be deemed to be the date on which the Option is granted for all purposes, unless the Committee otherwise specifies in its approval. However, the granting of an Option under the Plan shall be effective only if a written
Stock Option Agreement is duly executed and delivered by or on behalf of the Company and the Participant. 
  
 In addition to the foregoing, all Stock Option Agreements shall include without limitation the following provisions: 
  
 (a) Vesting. 
  
 Each Option shall be exercisable only with respect to the
Shares which have become vested pursuant to the terms of that Option. Each Option shall become vested with respect to Shares subject to that Option on such date or dates and on the basis of such other criteria, including without limitation
performance of the Company, as the Committee may determine, in its sole discretion, and shall be specified in the applicable Stock Option Agreement. The Committee shall have the authority, in its sole discretion, to accelerate the time at which an
Option shall be exercisable whenever it may determine that such action is appropriate by reason of changes in applicable tax or other laws or other changes in circumstances occurring after the grant of such Option. 
  
 (b) Exercise Price. 
  
 The exercise price per Share issuable upon exercise of an
Option shall be determined by the Committee at the time of grant and set forth in the applicable Stock Option Agreement; provided that such exercise price shall not be less than 

 
the fair market value per Share on date the Option is granted. For purposes of the Plan, the fair market value of the Shares shall mean, as of any given
date, the (i) last reported sale price on the New York Stock Exchange on the most recent previous trading day, (ii) last reported sale price on the NASDAQ National Market System on the most recent previous trading day, (iii) mean between the high
and low bid and ask prices, as reported by the National Association of Securities Dealers, Inc. on the most recent previous trading day, or (iv) last reported sale price on any other stock exchange on which the Shares are listed on the most recent
previous trading day, whichever is applicable; provided that if none of the foregoing is applicable, then the fair market value of the Shares shall be the value determined by the Committee, in its sole discretion. 
  
 (c) Term. 
  
 No Option shall be exercisable after the expiration of 10
years from the date on which that Option is granted. 
  
 (d)
Method of Exercise. 
  
 An Option may be
exercised, in whole or in part, by giving written notice to the Company stating the number of Shares (which must be a whole number) to be purchased. Upon receipt of payment of the full purchase price for such Shares, plus applicable withholding
taxes, by certified or bank cashier’s check or other form of payment acceptable to the Company, or, if approved by the Committee, in its sole discretion, by (i) delivery of unrestricted Shares having a fair market value on the date of such
delivery equal to the total exercise price, (ii) surrender of Shares subject to the Option which have a fair market value equal to the total exercise price at the time of exercise, or (iii) a combination of the preceding methods, and subject to
compliance with all other terms and conditions of the Plan and the Stock Option Agreement relating to such Option, the Company shall issue, as soon as reasonably practicable after receipt of such payment, such Shares to the person entitled to
receive such Shares, or such person’s designated representative. Such Shares may be issued in the form of a certificate, by book entry, or otherwise, in the Company’s sole discretion. 
  
 (e) Restrictions on Shares Subject to Options. 
  
 Shares issued upon the exercise of any Option may be made
subject to such transferability or other restrictions or conditions as the Committee may determine, in its sole discretion, and as shall be set forth in the applicable Stock Option Agreement. 
  
 (f) Transferability. 
  
 Options shall not be transferable. Any attempted transfer
shall be null and void. All Options shall be exercisable during a Participant’s lifetime only by the Participant or the Participant’s legal representative. Notwithstanding the foregoing to the contrary: (i) Options may be transferred by a
Participant by will 

 
or the laws of descent and distribution; and (ii) the Committee may, in its sole discretion and in the manner established by the Committee, provide for the
irrevocable transfer, without payment of consideration, of any Option by a Participant to such Participant’s spouse, children, grandchildren, nieces, or nephews, to the trustee of any trust for the principal benefit of one or more such persons,
or to a partnership whose only partners are one or more such persons. In the case of such a permitted transfer, the Option shall be exercisable only by the transferee or such transferee’s legal representative. 
  
 (g) Termination of Status as an Eligible Director by Reason of Death or
Disability. 
  
 If a Participant’s
status as an Eligible Director terminates by reason of the Participant’s death or disability (as defined in Section 22(e)(3) of the Code, or as may otherwise be defined by the Committee from time to time, in its sole discretion, at or before
grant and included in the applicable Stock Option Agreement), then (i) unless otherwise determined by the Committee, in its sole discretion, at or before grant (and set forth in the Stock Option Agreement), to the extent an Option held by such
Participant is not vested as of the date of such termination, such Option shall automatically terminate on such date; and (ii) to the extent an Option held by such Participant is vested as of the date of such termination, such Option may thereafter
be exercised by the Participant, the legal representative of the Participant’s estate, the legatee of the Participant under the will of the Participant, the distributee of the Participant’s estate, or the Participant’s other successor
in interest, whichever is applicable, for a period of one year from the date of death or disability, or, if sooner, until the expiration of the stated term of the Option. 
  
 (h) Other Termination of Status as an Eligible Director. 
  
 If a Participant’s status as an Eligible Director
terminates for any reason other than death or disability, then (i) to the extent any Option held by such Participant is not vested as of the date of termination, such Option shall automatically terminate on such date; and (ii) unless otherwise
determined by the Committee, in its sole discretion, at or before grant (and set forth in the Stock Option Agreement), to the extent any Option held by such Participant is vested as of the date of such termination, such Option may thereafter be
exercised for a period of 90 days from the date of termination or, if sooner, until the expiration of the stated term of the Option; provided that, if the Participant’s status as an Eligible Director is terminated for Cause (as defined by the
Committee, in its sole discretion, from time to time, and included in the applicable Stock Option Agreement), any and all unexercised Options held by such Participant shall immediately lapse and be of no further force or effect. For purposes of the
Plan, whether termination of a Participant’s status as an Eligible Director is for “Cause” shall be determined by the Committee, in its sole discretion. 

 (i) Effect of Termination of Participant’s Status as an Eligible Director on Transferee.

  
 No Option held by a transferee of a
Participant pursuant to Section 5(f), above, shall remain exercisable for any period of time longer than would otherwise be permitted under Section 5(g) and 5(h). 
  
 Section 6. Restriction On Exercise After Termination. 
  
 Notwithstanding any provision of this Plan to the contrary, no unexercised right created under this Plan (an
“Unexercised Right”) shall be exercisable if, prior to such exercise, the Participant violates any non-competition, confidentiality, conflict of interest, or similar provision set forth in the Stock Option Agreement pursuant to which such
Unexercised Right was awarded or otherwise conducts himself in a manner adversely affecting the Company or any subsidiary of the Company, as determined by the Committee, in its sole discretion. 
  
 Section 7. Withholding Tax. 
  
 The Company, at its option, shall have the right to require the Participant
or any other person receiving Shares under the Plan to pay the Company the amount of any taxes which the Company is required to withhold with respect to such Shares or, in lieu of such payment, to retain or sell without notice a number of such
Shares sufficient to cover the amount required to be so withheld. The Company, at its option, shall have the right to deduct from all dividends paid with respect to Shares the amount of any taxes which the Company is required to withhold with
respect to such dividend payments. The obligations of the Company under the Plan shall be conditional on such payment or other arrangements acceptable to the Company. 
  
 Section 8. Securities Law Restrictions. 
  
 No right under the Plan shall be exercisable and no Share shall be delivered under the Plan except in compliance with all applicable federal and state
securities laws and regulations. The Company shall not be required to deliver any Shares or other securities under the Plan prior to such registration or other qualification of such Shares or other securities under any state or federal law, rule, or
regulation as the Committee shall determine to be necessary or advisable, in its sole discretion. 
  
 The Committee may require each person acquiring Shares under the Plan to make such representations, warranties, and agreements with respect to the
investment intent of such person or persons as the Committee may reasonably request. Any certificates for such Shares may include any legend which the Committee deems appropriate to reflect any restrictions on transfer. 
  
 All Shares or other securities delivered under the Plan shall be subject to
such stop-transfer orders and other restrictions as the Committee may deem advisable, in its sole discretion, under the rules, regulations, and other requirements of the Securities and Exchange Commission, any stock exchange upon which the Shares
are then listed, and 

 
any applicable federal or state securities law, and the Committee may cause a legend or legends to be put on any certificates evidencing such Shares to make
appropriate reference to such restrictions. 
  
 Section 9. Change in Capital
Structure. 
  
 In the event the Company changes its
outstanding Shares by reason of stock splits, stock dividends, or any other increase or reduction of the number of outstanding Shares without receiving consideration in the form of money, services, or property deemed appropriate by the Board, in its
sole discretion, the aggregate number of Shares subject to the Plan shall be proportionately adjusted and the number of Shares and the exercise price for each Share subject to the unexercised portion of any then-outstanding Option shall be
proportionately adjusted with the objective that the Participant’s proportionate interest in the Company shall remain the same as before the change without any change in the total exercise price applicable to the unexercised portion of any
then-outstanding Options, all as determined by the Committee, in its sole discretion. 
  
 In the event of any other recapitalization or any merger, consolidation, or other reorganization of the Company, the Committee shall make such adjustment, if any, as it may deem appropriate to accurately reflect the
number and kind of Shares deliverable, and the exercise prices payable, upon subsequent exercise of any then-outstanding Options, as determined by the Committee, in its sole discretion. 
  
 The Committee’s determination of the adjustments appropriate to be made under this Section 9 shall be conclusive upon
all Participants under the Plan. 
  
 Section 10. Change in Control.

  
 (a) Accelerated Vesting and Company Purchase Option.

  
 Notwithstanding any provision of this Plan or
any Stock Option Agreement to the contrary (unless such Stock Option Agreement contains a provision referring specifically to this Section 10 and stating that this Section 10 shall not be applicable to the Option evidenced by such Stock Option
Agreement), if a Change in Control (as defined below) occurs, then: 
  

	 	(i)	Any and all Options theretofore granted and not fully vested shall thereupon become vested and exercisable in full and shall remain so exercisable in accordance with their terms;
provided that no Option which has previously been exercised or otherwise terminated shall become exercisable; and 

  

	 	(ii)	The Company may, at its option, terminate any or all unexercised Options and portions thereof not more than 30 days after such Change in Control; provided that the Company shall,
upon such termination and with respect to each Option so terminated, pay to the Participant (or such Participant’s transferee, if applicable) theretofore holding such Option cash in an amount equal to the 

 difference between the fair market value (as defined in Section 5(a), above) of the Shares subject to
the Option at the time the Company exercises its option under this Section 10(a)(ii) and the exercise price of the Option, less applicable withholding taxes; and provided further that if such fair market value is less than such exercise price, then
the Committee may, in its sole discretion, terminate such Option without any payment. 
  
 (b) Definition of Change in Control. 
  
 For purposes of the Plan, a “Change in Control” means the happening of any of the following: 
  

	 	(i)	The direct or indirect acquisition by any “person” as defined in §3(a)(9) of the Securities Exchange Act of 1934, as amended (the “1934 Act”), and as used
in §§13(d) and 14(d) thereof, including a “group” within the meaning of §13(d) of the 1934 Act (hereinafter, simply a “Person”), of “beneficial ownership” (within the meaning of Rule 13d-3 under the 1934
Act) of securities of the Company representing more than 50% of the combined voting power of the Company’s then outstanding voting securities entitled to vote generally in the election of directors of the Company (the “Company Voting
Securities”); provided that: (A) for purposes of this subsection (i), the term “Person” shall not include the Company, any subsidiary of the Company, or any employee benefit plan sponsored or maintained by the Company or any
subsidiary of the Company (including any trustee of such plan acting as trustee); and (B) the provisions of this subsection (i) shall not apply to (1) any acquisition of securities from the Company or any of its subsidiaries, or (2) any acquisition
of securities pursuant to a Business Combination (as defined below) which satisfies clauses (A) and (B) of subsection (iii) of this §10(b); 

  

	 	(ii)	When, during any period of 24 consecutive months during the existence of the Plan, the individuals who, at the beginning of such period constitute the Board (the “Incumbent
Directors”) cease for any reason other than death to constitute at least at least a majority of the Board; provided, however, that a director who was not a director at the beginning of such 24-month period shall be deemed to have satisfied such
24-month requirement (and be an Incumbent Director) if such director was elected by, or on the recommendation of or with the approval of, at least two-thirds of the directors who then qualified as Incumbent Directors either actually (because they
were directors at the beginning of such 24-month period) or by prior operation of this §10 (b)(ii); or 

	 	(iii)	Approval by the stockholders of the Company of a reorganization, merger, consolidation, or recapitalization of the Company, or a sale or other disposition of all or substantially
all of the assets of the Company, or the acquisition of the assets of another corporation or other entity (any such transaction, a “Business Combination”), or the consummation of a Business Combination for which stockholder approval is not
obtained, unless, in any such case, following such Business Combination: (A) all or substantially all of the individuals and entities who were the beneficial owners of the Company Voting Securities outstanding immediately prior to such Business
Combination beneficially own, directly or indirectly, immediately following such Business Combination, more than 50% of the combined voting power of the then outstanding voting securities entitled to vote generally in the election of directors (or
their equivalent) of the corporation or other entity resulting from such Business Combination in substantially the same proportions as their ownership of the Company Voting Securities immediately prior to such Business Combination, and (B) at least
a majority of the members of the board of directors (or its equivalent) of the corporation or other entity resulting from such Business Combination were Incumbent Directors at the time of the execution of the initial agreement, or of the action of
the Board, providing for such Business Combination; or 

  

	 	(iv)	Approval by the stockholders of the Company of a complete liquidation or dissolution of the Company. 

  
 Section 11. Six-Month Holding Period. 
  
 If an exemption from Section 16(b) of the 1934 Act is not otherwise available under 1934 Act Rule 16b-3(d)(1) or (2), then Shares purchased upon exercise
of an Option may not be sold before at least six months have elapsed from the date the Option was granted. 
  
 Section 12. No Enlargement of Rights. 
  
 The adoption of this Plan and the grant of one or more Options to an Eligible Director shall not confer any right to the Eligible Director to continue in the status of Eligible Director and shall not restrict or
interfere in any way with the right of the Company to terminate such Eligible Director’s status as such at any time, with or without cause. 
  
 Section 13. Rights as Stockholder. 
  
 No Participant or his executor or administrator or other transferee shall have any rights of a stockholder in the Company with respect to the Shares
covered by an Option unless and until a certificate representing such Shares has been duly issued and delivered to him under the Plan. 

 Section 14. Acceleration of Rights. 
  
 The Committee shall have the authority, in its sole discretion, to accelerate the time at which an Option shall be
exercisable whenever it may determine that such action is appropriate by reason of changes in applicable tax or other laws or other changes in circumstances occurring after the award of such Option. 
  
 Section 15. Definition of Subsidiary. 
  
 The term “subsidiary,” when used in the Plan or any Stock Option
Agreement made pursuant to the Plan, shall mean (a) any subsidiary corporation of the Company as defined in Section 424(f) of the Code and the Treasury Regulations promulgated thereunder (the “Regulations”), (b) any limited liability
company in which the Company or any of its subsidiaries is the sole member, and (c) any limited partnership (i) in which the Company or one of its subsidiaries owns 50 percent or more of the combined voting power of all classes of equity, and (ii)
which has elected to be taxed as a corporation for federal income tax purposes. 
  
 Section 16. Interpretation, Amendment or Termination of Plan. 
  
 The interpretation by the Committee of any provision of the Plan or of any Stock Option Agreement executed pursuant to the grant of an Option under the Plan shall be final and conclusive upon all Participants or
transferees under the Plan. The Board, without further action on the part of the stockholders of the Company, may from time to time alter, amend, or suspend the Plan or may at any time terminate the Plan; provided that: (a) no such action shall
adversely affect any Participant’s rights with respect to outstanding Options then held by such Participant without such Participant’s consent; and (b) except for the adjustments provided for in Section 9, above, no amendment may be made
by Board action without stockholder approval if the amendment would require stockholder approval under applicable law or regulation, or if the amendment is a “material amendment” as defined below. Subject to the above provisions, the Board
shall have authority to amend the Plan to take into account changes in applicable tax and securities laws and accounting rules, stock exchange or market rules, as well as other developments. 
  
 For the purposes of this Section 16, a “material amendment” to the
Plan shall mean: 
  
 (1) any material increase in the number of
Shares to be issued under the Plan (other than to reflect a reorganization, stock split, merger, spinoff or similar transaction); 
  
 (2) any material increase in benefits to Participants, including any amendment to: (a) permit a repricing (as defined below) of outstanding Stock Options,
(b) reduce the price at which Stock Options may be offered, or (c) extend the duration of the Plan; 

 (3) any material expansion of the class of Participants eligible to participate in the Plan; and

  
 (4) any expansion in the type of Options provided under the
Plan. 
  
 The Committee may amend the terms of any Option
theretofore granted, prospectively or retroactively; provided, no such amendment shall impair the rights of any Participant without the Participant’s consent, unless it is made to cause the Plan or such Option to comply with applicable law,
stock exchange or market rules or accounting rules. Notwithstanding the foregoing, the Committee may not adjust or amend the exercise price of Options previously granted, whether through amendment, cancellation or replacement grants or any other
means (a “repricing”) unless the Company obtains stockholder approval for such repricing. 
  
 Section 17. Protection of Board and Committee. 
  
 No member of the Board or the Committee shall have any liability for any determination or other action made or taken in good faith with respect to the Plan or any Option granted under the Plan. 
  
 Section 18. Government Regulations. 
  
 Notwithstanding any provision of the Plan or any Stock Option Agreement
executed pursuant to the Plan, the Company’s obligations under the Plan and such Agreement shall be subject to all applicable laws, rules, and regulations and to such approvals as may be required by any governmental or regulatory agencies,
including without limitation any stock exchange on which the Shares may then be listed. 
  
 Section 19. Governing Law. 
  
 The Plan shall be
construed and governed by the laws of the State of Delaware. 
  
 Section 20.
Genders and Numbers. 
  
 When permitted by the context,
each pronoun used in the Plan shall include the same pronoun in other genders and numbers. 

 Section 21. Captions. 
  
 The captions of the various sections of the Plan are not part of the context of the Plan, but are only labels to assist in locating those sections, and
shall be ignored in construing the Plan. 
  
 Section 22. Effective Date.

  
 The Plan shall be effective April 26, 2005 (the
“Effective Date”); provided that if the Plan is not approved by the Company’s stockholders at the annual meeting of the stockholders to be held on the Effective Date, or at any adjournment of that meeting, then the Plan shall
automatically become null and void and have no further force or effect. 
  
 Section 23. Term of Plan. 
  
 No Option shall be
granted pursuant to the Plan on or after the 10th anniversary of the Effective Date, but Options granted prior to
such tenth anniversary may extend beyond that date. 
  
 Section 24. Savings
Clause. 
  
 In case any one or more of the provisions of this
Plan shall be held invalid, illegal, or unenforceable in any respect, the validity, legality, and enforceability of the remaining provisions shall not in any way be affected or impaired thereby, and the invalid, illegal, or unenforceable provision
shall be deemed null and void; however, to the extent permissible by law, any provision which could be deemed null and void shall first be construed, interpreted, or revised retroactively to permit this Plan to be construed so as to foster the
intent of this Plan. This Plan and all transactions pursuant to this Plan are intended to comply in all respects with applicable law and regulation, including, with respect to persons subject to Section 16 of the 1934 Act (“Reporting
Persons”), Rule 16b-3 under the 1934 Act. In case any one or more of the provisions of this Plan or any transaction pursuant to this Plan shall be held to violate or be unenforceable in any respect under Rule 16b-3, then, to the extent
permissible by law, any provision which could be deemed to violate or be unenforceable under Rule 16b-3 shall first be construed, interpreted, or revised retroactively to permit the Plan or transaction to be in compliance with Rule 16b-3.Stock Option Agreement for 2005 Equity Incentive Plan

                             (the “Participant”) an option (the “Option”) to
purchase              shares of the Company’s common stock, $.01 par value (the “Shares”), for a purchase price of
$             per Share (the “Option Price”). The Option has been granted pursuant to the American Dental Partners, Inc. 2005 Equity Incentive Plan, as amended (the
“Plan”), and shall include and be subject to all provisions of the Plan, which are hereby incorporated herein by reference. The Option shall also be subject to the following provisions of this agreement: 
  
 §1. Vesting. The Option shall be exercisable only with respect
to the Shares which have become “vested” from time to time under this agreement. The Option shall vest with respect to       % of the Shares subject to the Option on each of the first
             anniversaries of the date the Option is granted, as set forth at the end of this agreement (the “Grant Date”), so that the Option shall become vested with
respect to the following percentages of the total number of Shares subject to the Option (computed cumulatively and rounded to the nearest whole number of Shares) on the following anniversaries of the Grant Date, respectively, subject to the
Participant’s continuous status as an employee of the Company or any of its subsidiaries on such dates: 
  

			
	 Date:

	 	 Percentage

  
  
 §2. Term. The Option shall expire on tenth anniversary of the Grant Date to the extent not previously exercised but shall be subject to
earlier termination as provided in Sections 6 and 13 of the Plan. Upon termination of the Participant’s employment by the Company and all of its subsidiaries, any portion of the Option which has not become vested as of the date of such
termination shall terminate automatically as of such date. 
  
 §3. Method of Exercise. At any time when the Option is exercisable under the Plan and this agreement, and subject to any applicable restrictions on exercise of the Option under the Plan or this agreement, the Option shall be
exercisable, in whole or in part, from time to time during the term of the Option by written notice to the Company at its principal office, which notice shall: 
  

(a) State that the Option is being exercised thereby and specify the number of Shares (which must be a whole number) with respect to
which the Option is being exercised, the name of each person in whose name any such Shares should be registered, his address, and his social security number; 
  

(b) Be signed by the person or persons entitled to exercise the Option and, if the Option is being exercised by anyone other than the
Participant, be accompanied by proof satisfactory to counsel for the Company of the right of such person or persons to exercise the Option under the Plan and all applicable laws and regulations; and 
  
 (c) Contain representations, warranties, and agreements with
respect to the investment intention of such person or persons in form and substance satisfactory to counsel for the Company. 

 §4. Notice of Disposition. The person exercising the Option shall notify the Company when
making any disposition of the Shares acquired upon exercise of the Option, whether by sale, gift or otherwise. 
  
 §5. Payment of Price. Upon exercise of the Option with respect to any of the Shares and payment of the purchase price and any applicable
withholding taxes for such Shares in a manner permissible under the Plan, the Company shall issue the Shares to the specified person or persons as provided in the Plan. 
  
 §6. Transferability. The Option shall not be transferable by the Participant except as provided in the Plan.
Unless transferred as provided in the Plan, the Option shall be exercisable during the lifetime of the Participant (subject to any other applicable restrictions on exercise) only by the Participant (or his legal representative) for his own account.

  
 §7. Restrictions. The Option and any Shares issued
upon exercise of the Option shall be subject to all restrictions in this agreement or in the Plan. As a condition of any exercise of the Option, the Company may require the Participant or his successor to make any representation and warranty to
comply with any applicable law or regulation or to confirm any factual matters reasonably requested by counsel for the Company. 
  
 §8. Nonqualified Stock Option. The Option is not intended to qualify as an incentive stock option under §422 of the Internal Revenue Code
of 1986, as amended. 
  
 §9. Construction. In the
event of any inconsistency between the provisions of the Plan and the provisions of this agreement, the provisions of the Plan shall control.
