Award Agreements granted from time to time or at the same time need not contain similar provisions but shall be consistent with the terms of the Plan. Each Award Agreement evidencing a Grant of Options shall specify whether such Options are intended to be Non-qualified Stock Options or Incentive Stock Options, and in the absence of such specification such options shall be deemed Non-qualified Stock Options.

The Option Price of each Option shall be fixed by the Board and stated in the Award Agreement evidencing such Option. The Option Price of each Option shall be at least the Fair Market Value on the Grant Date of a share of Stock; provided, however, that in the event that a Grantee is a Ten-Percent Shareholder, the Option Price of an Option granted to such Grantee that is intended to be an Incentive Stock Option shall be not less than 110% of the Fair Market Value of a share of Stock on the Grant Date.

7.4 Termination of Service.

Each Award Agreement shall set forth the extent to which the Grantee shall have the right to exercise the Option following termination of the Grantee’s Service. Such provisions shall be determined in the sole discretion of the Board, need not be uniform among all Options issued pursuant to the Plan, and may reflect distinctions based on the reasons for termination of Service.

7.5 Limitations on Exercise of Option.

Notwithstanding any other provision of the Plan, in no event may any Option be exercised, in whole or in part, prior to the date the Plan is approved by the shareholders of the Company as provided herein or after the occurrence of an event referred to in Section 14 hereof which results in termination of the Option.

7.6 Method of Exercise.

An Option that is exercisable may be exercised by the Grantee’s delivery to the Company of written notice of exercise on any business day, at the Company’s principal office, on the form specified by the Company. Such notice shall specify the number of shares of Stock with respect to which the Option is being exercised and shall be accompanied by payment in full of the Option Price of the shares for which the Option is being exercised plus the amount (if any) of federal and/or other taxes which the Company may, in its judgment, be required to withhold with respect to a Grant.

Except as provided in Section 14 hereof, no adjustment shall be made for dividends, distributions or other rights for which the record date is prior to the date of such issuance.

7.8 Delivery of Stock Certificates.

Promptly after the exercise of an Option by a Grantee and the payment in full of the Option Price, such Grantee shall be entitled to the issuance of a stock certificate or certificates evidencing his or her ownership of the shares of Stock subject to the Option.

7.9 Transferability of Options.

Except as provided in Section 7.10, during the lifetime of a Grantee, only the Grantee (or, in the event of legal incapacity or incompetency, the Grantee’s guardian or legal representative) may exercise an Option. Except as provided in Section 7.10, no Option shall be assignable or transferable by the Grantee to whom it is granted, other than by will or the laws of descent and distribution.

7.10 Family Transfers.

If authorized in the applicable Award Agreement, a Grantee may transfer, not for value, all or part of an Option which is not an Incentive Stock Option to any Family Member. For the purpose of this Section 7.10, a “not for value” transfer is a transfer which is (i) a gift, (ii) a transfer under a domestic relations order in settlement of marital property rights; or (iii) a transfer to an entity in which more than fifty percent of the voting interests are owned by Family Members (or the Grantee) in exchange for an interest in that entity.

Subsequent transfers of transferred Options are prohibited except to Family Members of the original Grantee in accordance with this Section 7.10 or by will or the laws of descent and distribution. The events of termination of Service of Section 7.4 hereof shall continue to be applied with respect to the original Grantee, following which the Option shall be exercisable by the transferee only to the extent, and for the periods specified in Section 7.4.

7.11 Limitations on Incentive Stock Options.

An Option shall constitute an Incentive Stock Option only (i) if the Grantee of such Option is an employee of the Company or any Subsidiary of the Company; (ii) to the extent specifically provided in the related Award Agreement; and (iii) to the extent that the aggregate Fair Market Value (determined at the time the Option is granted) of the shares of Stock with respect to which all Incentive Stock Options held by such Grantee become exercisable for the first time during any calendar year (under the Plan and all other plans of the Grantee’s employer and its affiliates) does not exceed $100,000. This limitation shall be applied by taking Options into account in the order in which they were granted.

7.12 Notice of Disqualifying Disposition.

If any Grantee shall make any disposition of shares of Stock issued pursuant to the exercise of an Incentive Stock Option under the circumstances described in Code Section 421(b) (relating to certain disqualifying dispositions), such Grantee shall notify the Company of such disposition within 10 days thereof.

8.1 Grant of Restricted Stock.

Awards of Restricted Stock may be made for no consideration (other than par value of the shares which is deemed paid by Services already rendered).

8.2 Restrictions.

At the time a Grant of Restricted Stock is made, the Board shall establish a restriction period applicable to such Restricted Stock. Each Grant of Restricted Stock may be subject to a different restricted period. The Board may, in its sole discretion, at the time a Grant of Restricted Stock is made, prescribe restrictions in addition to or other than the expiration of the restricted period, including the satisfaction of corporate or individual performance objectives, which may be applicable to all or any portion of the Restricted Stock. To the extent required by applicable law, the vesting restrictions applicable to a Grant of Restricted Stock shall lapse no less rapidly than the rate of 20% per year for each of the first five years from the Grant Date, based on continued Service.

The Board also may, in its sole discretion, shorten or terminate the restriction period or waive any of the conditions applicable to all or a portion of the Restricted Stock. The Restricted Stock may not be sold, transferred, assigned, pledged or otherwise encumbered or disposed of during the restricted period or prior to the satisfaction of any other restrictions prescribed by the Board with respect to such Restricted Stock.

8.3 Restricted Stock Certificates.

The Company shall issue, in the name of each Grantee to whom Restricted Stock has been granted, stock certificates representing the total number of shares of Restricted Stock granted to the Grantee, as soon as reasonably practicable after the Grant Date. The Board may provide in an Award Agreement that either (i) the Secretary of the Company shall hold such certificates for the Grantee’s benefit until such time as the Restricted Stock is forfeited to the Company, or the restrictions lapse, or (ii) such certificates shall be delivered to the Grantee, provided, however, that such certificates shall bear a legend or legends that comply with the applicable securities laws and regulations and makes appropriate reference to the restrictions imposed under the Plan and the Award Agreement.

8.4 Rights of Holders of Restricted Stock.

Unless the Board otherwise provides in an Award Agreement, holders of Restricted Stock shall have the right to vote such Stock and the right to receive any dividends declared or paid with respect to such Stock. The Board may provide that any dividends paid on Restricted Stock must be reinvested in shares of Stock, which may or may not be subject to the same vesting conditions and restrictions applicable to such Restricted Stock. All distributions, if any, received by a Grantee with respect to Restricted Stock as a result of any stock split, stock dividend, combination of shares, or other similar transaction shall be subject to the restrictions applicable to the original Grant.

8.5 Termination of Service.

Unless the Board otherwise provides in an Award Agreement or in writing after the Award Agreement is issued, upon the termination of a Grantee’s Service, any Restricted Stock held by such Grantee that have not vested, or with respect to which all applicable restrictions and conditions have not lapsed, shall immediately be deemed forfeited. Upon forfeiture of Restricted Stock, the Grantee shall have no further rights with respect to such Grant, including but not limited to any right to vote Restricted Stock or any right to receive dividends with respect to shares of Restricted Stock.

8.6 Purchase and Delivery of Restricted Stock.

The Grantee shall be required, to the extent required by applicable law, to purchase the Restricted Stock from the Company at a Purchase Price equal to the greater of (i) the aggregate par value of the shares of Stock represented by such Restricted Stock or (ii) the Purchase Price, if any, specified in the Award Agreement relating to such Restricted Stock. The Purchase Price shall be payable in a form described in Section 9 or, in the discretion of the Board, in consideration for past Services rendered to the Company or an Affiliate.

Upon the expiration or termination of any restricted period and the satisfaction of any other conditions prescribed by the Board, the restrictions applicable to shares of Restricted Stock shall lapse, and, unless otherwise provided in the Award Agreement, a stock certificate for such shares shall be delivered, free of all such restrictions, to the Grantee or the Grantee’s beneficiary or estate, as the case may be.

9.1 General Rule.

Payment of the Option Price for the shares purchased pursuant to the exercise of an Option or the Purchase Price for Restricted Stock shall be made in cash or in cash equivalents acceptable to the Company.

9.2 Surrender of Stock.

To the extent the Award Agreement so provides, payment of the Option Price for shares purchased pursuant to the exercise of an Option or the Purchase Price for Restricted Stock may be made all or in part through the tender to the Company of shares of Stock, which shall be valued, for purposes of determining the extent to which the Option Price or Purchase Price has been paid thereby, at their Fair Market Value on the date of exercise or surrender.

9.3 Cashless Exercise.

With respect to an Option only (and not with respect to Restricted Stock), to the extent permitted by law and to the extent the Award Agreement so provides and the shares of Stock have become publicly traded, payment of the Option Price for shares purchased pursuant to the exercise of an Option may be made all or in part by delivery (on a form acceptable to the Board) of an irrevocable direction to a licensed securities broker acceptable to the Company to sell shares of Stock and to deliver all or part of the sales proceeds to the Company in payment of the Option Price and any withholding taxes described in Section 10.

-11-

9.4 Other Forms of Payment.

To the extent the Award Agreement so provides, payment of the Option Price for shares purchased pursuant to exercise of an Option or the Purchase Price for Restricted Stock may be made in any other form that is consistent with applicable laws, regulations and rules.

The Company or any Affiliate, as the case may be, shall have the right to deduct from payments of any kind otherwise due to a Grantee any Federal, state, or local taxes of any kind required by law to be withheld with respect to the vesting of or other lapse of restrictions applicable to Restricted Stock or upon the issuance of any shares of Stock upon the exercise of an Option. At the time of such vesting, lapse, or exercise, the Grantee shall pay to the Company or Affiliate, as the case may be, any amount that the Company or Affiliate may reasonably determine to be necessary to satisfy such withholding obligation. Subject to the prior approval of the Company or the Affiliate, which may be withheld by the Company or the Affiliate, as the case may be, in its sole discretion, the Grantee may elect to satisfy such obligations, in whole or in part, (1) by causing the Company or the Affiliate to withhold shares of Stock otherwise issuable to the Grantee or (ii) by delivering to the Company or the Affiliate shares of Stock already owned by the Grantee. The shares of Stock so delivered or withheld shall have an aggregate Fair Market Value equal to such withholding obligations. The Fair Market Value of the shares of Stock used to satisfy such withholding obligation shall be determined by the Company or the Affiliate as of the date that the amount of tax to be withheld is to be determined. A Grantee who has made an election pursuant to this Section 10 may satisfy his or her withholding obligation only with shares of Stock that are not subject to any repurchase, forfeiture, unfulfilled vesting, or other similar requirements.

11.1 Right of First Refusal.

Subject to Section 11.4 below, a Grantee (or such other individual who is entitled to exercise an Option or otherwise acquire shares pursuant to a Grant under the terms of this Plan) shall not sell, pledge, assign, gift, transfer, or otherwise dispose of any shares of Stock acquired pursuant to a Grant to any person or entity without first offering such shares to the Company for purchase on the same terms and conditions as those offered the proposed transferee. The Company may assign its right of first refusal under this Section 11.1 in whole or in part, to (i) any holder of stock or other securities of the Company, (ii) any Affiliate or (iii) any other person or entity that the Board determines has a sufficient relationship with or interest in the Company. The Company shall give reasonable written notice to the Grantee of any such assignment of its rights. The restrictions of this Section 11.1 apply to any person to whom Stock that was originally acquired pursuant to a Grant is sold, pledged, assigned, bequeathed, gifted, transferred or otherwise disposed of, without regard to the number of such subsequent transferees or the manner in which they acquire the Stock, but the restrictions of this Section 11.1 do not apply to a transfer of Stock that occurs as a result of the death of the Grantee or of any subsequent transferee (but shall apply to the executor, the administrator or personal representative, the estate, and the legatees, beneficiaries and assigns thereof).

-12-

11.2 Repurchase and Other Rights.

Stock issued upon exercise of an Option or pursuant to the Grant of Restricted Stock may be subject to such right of repurchase or other transfer restrictions as the Board may determine, consistent with applicable law. Any such additional restriction shall be set forth in the Award Agreement.

11.3.2 Exception in the Case of Stock Repurchase Right.

If an Award Agreement authorizes, upon the Grantee’s termination of Service, the repurchase of shares of Stock acquired by the Grantee pursuant to the exercise of an Option or under a Grant of Restricted Stock, to the extent required by applicable law, payment shall be made in cash or by cancellation of indebtedness within the later of 90 days from the date of termination of Service or 90 days from the date of exercise or purchase, as the case may be.

11.4 Publicly Traded Stock.

If the Stock is listed on an established national or regional stock exchange or is admitted to quotation on The Nasdaq Stock Market, Inc., or is publicly traded in an established securities market, the foregoing transfer restrictions of Sections 11.1 and 11.2 shall terminate as of the first date that the Stock is so listed, quoted or publicly traded.

11.5 Legend.

Notwithstanding any other provision of this Plan or of any other agreement, contract, or understanding heretofore or hereafter entered into by a Grantee with the Company or any Affiliate, except an agreement, contract, or understanding that expressly addresses Section 280G or Section 4999 of the Code (an “Other Agreement”), and notwithstanding any formal or informal plan or other arrangement for the direct or indirect provision of compensation to the Grantee (including groups or classes of Grantees or beneficiaries of which the Grantee is a member), whether or not such compensation is deferred, is in cash, or is in the form of a benefit to or for the Grantee (a “Benefit Arrangement”), if the Grantee is a “disqualified individual,” as defined in Section 280G(c) of the Code, any Option or Restricted Stock held by that Grantee and any right to receive any payment or other benefit under this Plan shall not become exercisable or vested (i) to the extent that such right to exercise, vesting, payment, or benefit, taking into account all other rights, payments, or benefits to or for the Grantee under this Plan, all Other Agreements, and all Benefit Arrangements, would cause any payment or benefit to the Grantee under this Plan to be considered a “parachute payment” within the meaning of Section 280G(b)(2) of the Code as then in effect (a “Parachute Payment”) and (ii) if, as a result of receiving a Parachute Payment, the aggregate after-tax amounts received by the Grantee from the Company under this Plan, all Other Agreements, and all Benefit Arrangements would be less than the maximum after-tax amount that could be received by the Grantee without causing any such payment or benefit to be considered a Parachute Payment. In the event that the receipt of any such right to exercise, vesting, payment, or benefit under this Plan, in conjunction with all other rights, payments, or benefits to or for the Grantee under any Other Agreement or any Benefit Arrangement would cause the Grantee to be considered to have received a Parachute Payment under this Plan that would have the effect of decreasing the after-tax amount received by the Grantee as described in clause (ii) of the preceding sentence, then the Grantee shall have the right, in the Grantee’s sole discretion, to designate those rights, payments, or benefits under this Plan, any Other Agreements, and any Benefit Arrangements that should be reduced or eliminated so as to avoid having the payment or benefit to the Grantee under this Plan be deemed to be a Parachute Payment.

13.1 General.

The Company shall not be required to sell or issue any shares of Stock under any Grant if the sale or issuance of such shares would constitute a violation by the Grantee, any other individual exercising an Option, or the Company of any provision of any law or regulation of any governmental authority, including without limitation any federal or state securities laws or regulations. If at any time the Company shall determine, in its discretion, that the listing, registration or qualification of any shares subject to a Grant upon any securities exchange or under any governmental regulatory body is necessary or desirable as a condition of, or in connection with, the issuance or purchase of shares hereunder, no shares of Stock may be issued or sold to the Grantee or any other individual exercising an Option pursuant to such Grant unless such listing, registration, qualification, consent or approval shall have been effected or obtained free of any conditions not acceptable to the Company, and any delay caused thereby shall in no way affect the date of termination of the Grant. Without limiting the generality of the foregoing, in connection with the Securities Act, upon the exercise of any Option or the delivery of any shares of Restricted

-14-

Stock, unless a registration statement under the Securities Act is in effect with respect to the shares of Stock covered by such Grant, the Company shall not be required to sell or issue such shares unless the Board has received evidence satisfactory to it that the Grantee or any other individual exercising an Option may acquire such shares pursuant to an exemption from registration under the Securities Act. Any determination in this connection by the Board shall be final, binding, and conclusive. The Company may, but shall in no event be obligated to, register any securities covered hereby pursuant to the Securities Act. The Company shall not be obligated to take any affirmative action in order to cause the exercise of an Option or the issuance of shares of Stock pursuant to the Plan to comply with any law or regulation of any governmental authority. As to any jurisdiction that expressly imposes the requirement that an Option shall not be exercisable until the shares of Stock covered by such Option are registered or are exempt from registration, the exercise of such Option (under circumstances in which the laws of such jurisdiction apply) shall be deemed conditioned upon the effectiveness of such registration or the availability of such an exemption.

13.2 Rule 16b-3.

During any time when the Company has a class of equity security registered under Section 12 of the Exchange Act, it is the intent of the Company that Grants pursuant to the Plan and the exercise of Options granted hereunder will qualify for the exemption provided by Rule 16b-3 under the Exchange Act. To the extent that any provision of the Plan or action by the Board does not comply with the requirements of Rule 16b-3, it shall be deemed inoperative to the extent permitted by law and deemed advisable by the Board, and shall not affect the validity of the Plan. In the event that Rule 16b-3 is revised or replaced, the Board may exercise its discretion to modify this Plan in any respect necessary to satisfy the requirements of, or to take advantage of any features of, the revised exemption or its replacement.

13.3 Financial Reports.

To the extent required by applicable law, not less often than annually, the Company shall furnish to Grantees summary financial information including a balance sheet regarding the Company’s financial condition and results of operations, unless such Grantees have duties with the Company that assure them access to equivalent information. Such financial statements need not be audited.

14.1 Changes in Stock.

If the number of outstanding shares for which Grants of Options and Restricted Stock may be made under the Plan is increased or decreased or the shares underlying the Grants are changed into or exchanged for a different number or kind of shares or other securities of the Company on account of any recapitalization, reclassification, stock split, reverse split, combination of shares, exchange of shares, stock dividend or other distribution payable in capital stock, or other increase or decrease in such shares effected without receipt of consideration by the Company occurring after the Effective Date, the number and kinds of shares for which grants of Options and Restricted Stock may be made under the Plan shall be adjusted proportionately and according to the

-15-

Company. In addition, the number and kind of shares for which Grants are outstanding shall be adjusted proportionately and accordingly so that the proportionate interest of the Grantee immediately following such event shall, to the extent practicable, be the same as immediately before such event. Any such adjustment in outstanding Options shall not change the aggregate Option Price payable with respect to shares that are subject to the unexercised portion of an outstanding Option, but shall include a corresponding proportionate adjustment in the Option Price per share. The conversion of any convertible securities of the Company shall not be treated as an increase in shares effected without receipt of consideration. Notwithstanding the foregoing, in the event of any distribution to the Company’s shareholders of securities of any other entity or other assets (including an extraordinary dividend but excluding a non-extraordinary dividend of the Company) without receipt of consideration by the Company, the Company shall, in such manner as the Company deems appropriate, adjust (i) the number and kind of shares subject to outstanding Awards and/or (ii) the exercise price of outstanding Options to reflect such distribution.

14.2 Reorganization in Which the Company Is the Surviving Entity Which does not Constitute a Corporate Transaction.

Subject to Section 14.3 hereof, if the Company shall be the surviving entity in any reorganization, merger, or consolidation of the Company with one or more other entities which does not constitute a Corporate Transaction, any Grant theretofore made pursuant to the Plan shall pertain to and apply to the securities to which a holder of the number of shares of Stock subject to such Grant would have been entitled immediately following such reorganization, merger, or consolidation, and in the case of Options, with a corresponding proportionate adjustment of the Option Price per share so that the aggregate Option Price thereafter shall be the same as the aggregate Option Price of the shares remaining subject to the Option immediately prior to such reorganization, merger, or consolidation. Subject to any contrary language in an Award Agreement evidencing a Grant of Restricted Stock, any restrictions applicable to such Restricted Stock shall apply as well to any replacement shares received by the Grantee as a result of the reorganization, merger or consolidation.

14.3 Corporate Transaction.

Subject to the exceptions set forth in the last sentence of this Section 14.3 and the last sentence of Section 14.4 upon the occurrence of a Corporate Transaction:

(A) fifteen days prior to the scheduled consummation of a Corporate Transaction, all Options outstanding hereunder shall become immediately exercisable and shall remain exercisable for a period of fifteen days, or

(B) the Board may elect, in its sole discretion, to cancel any outstanding Grants and pay or deliver, or cause to be paid or delivered, to the holder thereof an amount in cash or securities having a value (as determined by the Board acting in good faith), in the case of Restricted Stock, equal to the formula or fixed price per share paid to holders of shares

-16-

of Stock and, in the case of Options, equal to the product of the number of shares of Stock subject to the Option (the “Option Shares”) multiplied by the amount, if any, by which (I) the formula or fixed price per share paid to holders of shares of Stock pursuant to such transaction exceeds (II) the Option Price applicable to such Option Shares. With respect to the Company’s establishment of an exercise window, (i) any exercise of an Option during such fifteen-day period shall be conditioned upon the consummation of the event and shall be effective only immediately before the consummation of the event, and (ii) upon consummation of any Corporate Transaction the Plan, and all outstanding but unexercised Options shall terminate. The Board shall send written notice of an event that will result in such a termination to all individuals who hold Options not later than the time at which the Company gives notice thereof to its shareholders.

This Section 14.3 shall not apply to any Corporate Transaction to the extent that provision is made in writing in connection with such Corporate Transaction for the assumption or continuation of the Options and Restricted Stock theretofore granted, or for the substitution for such Options and Restricted Stock for new common stock options and new common stock restricted stock relating to the stock of a successor entity, or a parent or subsidiary thereof, with appropriate adjustments as to the number of shares (disregarding any consideration that is not common stock) and option prices, in which event the Plan and Options and Restricted Stock theretofore granted shall continue in the manner and under the terms so provided.

14.4 Adjustments.

Adjustments under this Section 14 related to shares of Stock or securities of the Company shall be made by the Board, whose determination in that respect shall be final, binding and conclusive. No fractional shares or other securities shall be issued pursuant to any such adjustment, and any fractions resulting from any such adjustment shall be eliminated in each case by rounding downward to the nearest whole share. The Board shall determine the effect of a Corporate Transaction upon Grants of Options, and such effect shall be set forth in the appropriate Award Agreement. The Board may provide in the Award Agreements at the time of Grant, or any time thereafter with the consent of the Grantee, for different provisions to apply to a Grant in place of those described in Sections 14.1, 14.2 and 14.3.

14.5 No Limitations on Company.

The making of Grants pursuant to the Plan shall not affect or limit in any way the right or power of the Company to make adjustments, reclassifications, reorganizations, or changes of its capital or business structure or to merge, consolidate, dissolve, or liquidate, or to sell or transfer all or any part of its business or assets.

15.1 Effective Date.

The Plan shall be effective as of the Effective Date, subject to approval of the Plan by the Company’s shareholders within one year of the Effective Date. Under approval of the Plan by the shareholders of the Company as set forth above, all Grants made under the Plan on or after the Effective Date shall be fully effective as if the shareholders of the Company had approved the Plan on the Effective Date. If the shareholders fail to approve the Plan within one year of the Effective Date, any Grants made hereunder shall be null and void and of no effect.

-17-

15.2 Term.

The Plan shall terminate automatically ten years after its adoption by the Board and may be terminated on any earlier date as next provided.

15.3 Amendment and Termination of the Plan.

The Board may, at any time and from time to time, amend, suspend, or terminate the Plan as to any shares of Stock as to which Grants have not been made. An amendment to the Plan shall be contingent on approval of the Company’s shareholders only to the extent required by applicable law, regulations or rules. No Grants shall be made after the termination of the Plan. No amendment, suspension, or termination of the Plan shall, without the consent of the Grantee, alter or impair rights or obligations under any Grant theretofore awarded under the Plan.

16.1 Disclaimer of Rights.

No provision in the Plan or in any Grant or Award Agreement shall be construed to confer upon any individual the right to remain in the employ or service of the Company or any Affiliate, or to interfere in any way with any contractual or other right or authority of the Company either to increase or decrease the compensation or other payments to any individual at any time, or to terminate any employment or other relationship between any individual and the Company. In addition, notwithstanding anything contained in the Plan to the contrary, unless otherwise stated in the applicable Award Agreement, no Grant made under the Plan shall be affected by any changes of duties or position of the Grantee, so long as such Grantee continues to be a director, officer, consultant or employee of the Company or an Affiliate. The obligation of the Company to pay any benefits pursuant to this Plan shall be interpreted as a contractual obligation to pay only those amounts described herein, in the manner and under the conditions prescribed herein. The Plan shall in no way be interpreted to require the Company to transfer any amounts to a third party trustee or otherwise hold any amounts in trust or escrow for payment to any Grantee or beneficiary under the terms of the Plan.

16.2 Nonexclusivity of the Plan.

Neither the adoption of the Plan nor the submission of the Plan to the shareholders of the Company for approval shall be construed as creating any limitations upon the right and authority of the Board to adopt such other incentive compensation arrangements (which arrangements may be applicable either generally to a class or classes of individuals or specifically to a particular individual or particular individuals) as the Board in its discretion determines desirable, including, without limitation, the granting of stock options otherwise than under the Plan.

-18-

16.3 Captions.

The use of captions in this Plan or any Award Agreement is for the convenience of reference only and shall not affect the meaning of any provision of the Plan or such Award Agreement.

16.4 Other Provisions.

Each Grant awarded under the Plan may contain such other terms and conditions not inconsistent with the Plan as may be determined by the Board, in its sole discretion.

16.5 Number and Gender.

With respect to words used in this Plan, the singular form shall include the plural form, the masculine gender shall include the feminine gender, etc., as the context requires.

16.6 Severability.

If any provision of the Plan or any Award Agreement shall be determined to be illegal or unenforceable by any court of law in any jurisdiction, the remaining provisions hereof and thereof shall be severable and enforceable in accordance with their terms, and all provisions shall remain enforceable in any other jurisdiction.

16.7 Governing Law.

All rights and obligations under the Plan shall be governed, construed and interpreted in accordance with the laws of the State of Delaware, without giving effect to principles of conflicts of laws.

16.8 Section 409A of the Code.

The Board intends to comply with Section 409A of the Code (“Section 409A”), or an exemption to Section 409A, with regard to Awards hereunder that constitute nonqualified deferred compensation within the meaning of Section 409A. To the extent that the Board determines that a Grantee would be subject to the additional 20% tax imposed on certain nonqualified deferred compensation plans pursuant to Section 409A as a result of any provision of any Award granted under this Plan, such provision shall be deemed amended to the minimum extent necessary to avoid application of such additional tax. The nature of any such amendment shall be determined by the Board.

To record adoption of the Plan by the Board as of October 11, 2011, and approval of the Plan by the shareholders on October 11, 2011, the Company has caused its authorized officer to execute the Plan.
