TABLE OF CONTENTS
ABOUT THE ANNUAL MEETING
What is the purpose of the annual meeting?
At the annual meeting, we are asking stockholders:
·  To elect two (2) Class II directors, each for a three-year term ending in 2009;
·  To approve the Amended and Restated Dyadic International, Inc. 2001 Equity Compensation Plan effective as of January 1, 2005;

·  To ratify the appointment of Ernst & Young LLP as our independent registered public accounting firm for the year ending December 31, 2006; and
·  To transact such other business properly brought before the meeting and any adjournment or postponement of the meeting.
Who is entitled to notice of, and to vote at the annual meeting?
You are entitled to vote, in person or by proxy, at the annual meeting if you owned shares of our common stock as of the close of business (5:00 p.m. EST) on April 26, 2006, the record date of the annual meeting. On the record date, 23,140,467shares of our common stock were issued and outstanding and held by 154 holders of record. Holders of record of our common stock on the record date are entitled to one vote per share at the annual meeting.
Who can attend the meeting?
All stockholders as of the record date, or their duly appointed proxies, may attend. Please note that if you hold shares in “street name” (that is, through a broker or other nominee), you will need to bring a copy of a brokerage statement reflecting your stock ownership as of the record date.
What shares may I vote?
You may vote all shares you owned as of the record date. These include (1) shares owned directly in your name as stockholder of record and (2) shares held for you as the beneficial owner through a stockbroker, bank or other nominee.
What is the difference between holding shares as a stockholder of record and as a beneficial owner?
Most of our stockholders hold their shares through a stockbroker, bank or other nominee rather than directly in their own name. As summarized below, there are some differences between shares held of record and those beneficially owned.
If our shares are registered directly in your name with our transfer agent, Continental Stock Transfer & Trust Company, you are considered the stockholder of record with regard to those shares. As the stockholder of record, you have the right to grant your proxy directly to us to vote your shares on your behalf at the meeting or the right to vote in person at the meeting. We have enclosed or sent a proxy card for you to use.
If you hold our shares in a stock brokerage account or by a bank or other nominee, you are considered the beneficial owner of the shares held in “street name,” and these materials have been forwarded to you by your broker or nominee, which is considered the stockholder of record with respect to those shares. As the beneficial owner, you have the right to direct your broker or nominee how to vote and are also invited to attend the annual meeting so long as you bring a copy of a brokerage statement reflecting your ownership as of the record date. However, since you are not the stockholder of record, you may not vote these shares in person at the meeting unless you obtain

a signed proxy from your broker or nominee giving you the right to vote the shares. Your broker or nominee has enclosed or provided a voting instruction card for you to use to direct your broker or nominee how to vote these shares.
What constitutes a quorum?
If a majority of the shares of our common stock outstanding on the record date is represented either in person or by proxy at the annual meeting, a quorum will be present at the annual meeting. Shares held by persons attending the annual meeting but not voting, and shares represented in person or by proxy and for which the holder has abstained from voting, will be counted as present at the annual meeting for purposes of determining the presence or absence of a quorum.
A broker who holds shares in nominee or “street name” for a customer who is the beneficial owner of those shares may be prohibited from giving a proxy to vote those shares on any proposal to be voted on at the annual meeting without specific instructions from such customer with respect to such proposal. Accordingly, if a broker receives voting instructions from a customer with respect to one or more, but not all, of the proposals to be voted on at the annual meeting, the shares beneficially owned by such customer will not constitute “votes cast” or shares “entitled to vote” with respect to any proposal for which the customer has not provided voting instructions to the broker. These so-called “broker non-votes” will be counted as present at the annual meeting for purposes of determining whether a quorum exists.
How do I vote?
If you complete and properly sign and date the accompanying proxy card, and return it to us in the enclosed return envelope as soon as possible, it will be voted as you direct. If you are a registered stockholder and you attend the meeting, you may deliver your completed proxy card in person. “Street name” stockholders who wish to vote at the meeting will need to obtain a proxy from the broker or nominee that holds their shares.
All shares of our common stock represented by properly executed proxies received before or at the annual meeting will, unless revoked, be voted in accordance with the instructions indicated on those proxies. If no instructions are indicated on a properly executed proxy, the shares represented by such proxy card will be voted “FOR” the nominees for Class III directors, “FOR” the proposal to serve untilapprove the 2008 Annual Meeting of StockholdersAmended and until their successors are duly electedRestated 2001 Equity Compensation Plan, “FOR” the proposal to approve the 2006 Stock Option Plan and qualified; 2.

The foregoing matters are described in more detail in the enclosed Proxy Statement. Our Board of Directors has fixed the close of business on April 29, 2005 as the record date for the determination of our stockholders entitled to notice of, and to vote at, the Annual Meeting and any postponement or adjournment of the Annual Meeting. Only those stockholders of record as of the close of business on that date are entitled to notice of and to vote at the Annual Meeting. Our stock transfer books will remain open between the record date and the date of the Annual Meeting.

No proxy that is voted against all of the proposals will be voted in favor of any adjournment or postponement of the annual meeting for the purpose of soliciting additional proxies.

DYADIC INTERNATIONAL, INC. 2001 EQUITY COMPENSATION PLAN Incident to the consummation of the merger, we assumed the Dyadic International, Inc. 2001 Equity Compensation Plan adopted by Dyadic-Florida in 2001. The Equity Compensation Plan provides for the grant of options intended to qualify as incentive stock options or nonstatutory stock options that are not intended to so qualify, and awards of shares and stock appreciation rights. Options or awards may be granted to our employees, officers, directors, consultants and advisors and those of our subsidiaries. In addition to 1,350,389 shares of common stock we had reserved for issuance for outstanding options granted under the Equity Compensation Plan, as of April 20, 2005, we had an additional 3,783,434 shares reserved for future options and awards under the Equity Compensation Plan, subject to adjustment in the event of a stock split, stock dividend, recapitalization or similar capital change. The Equity Compensation Plan is administrated by a plan administrator, presently the Compensation Committee of our Board of Directors, which: o selects the eligible persons to whom awards and options are granted; o determines the number of shares subject to each award or option, the exercise price or purchase price for options, vesting or exercisability schedules, and such other terms and conditions as the administrator deems necessary or appropriate; o interprets the provisions of the Equity Compensation Plan; and o may, subject to certain limitations, amend the Equity Compensation Plan. Each award or option granted under the Equity Compensation Plan is required to be evidenced by a written agreement between us and the recipient of the award or option. 21 The exercise period, vesting schedule and the exercise price for all options granted under the Equity Compensation Plan is determined by the plan administrator. The exercise price for incentive stock options may not be less than the fair market value of our common stock on the date the option is granted, except for incentive stock options granted to 10% stockholders, which must have an exercise price of not less than 110% of the fair market value of our common stock on the date the option is granted. The exercise price for all nonstatutory stock options must be equal to or greater than the fair market value of our common stock. Incentive stock options have a maximum term of ten years, except for 10% stockholders who are subject to a maximum term of five years. Options are not transferable other than by will and the laws of descent and distribution. Options generally expire not later than 90 days following a termination of employment, 12 months following the optionee's disability, or not later than 12 months following the optionee's death. If any option expires, terminates or is canceled for any reason, or if shares of stock issued subject to a right of repurchase are repurchased by us, the shares allocable to the unexercised option or the repurchased shares will become available for additional option grants under the Equity Compensation Plan. The Equity Compensation Plan also confers discretion upon the plan administrator to accelerate the vesting schedules applicable to all awards and options upon the occurrence of a change of control. The term "change in control" is defined under the Equity Compensation Plan to mean: o a sale of all or substantially all of our assets, or our liquidation or dissolution, or a merger or consolidation in which our stockholders immediately prior to the transaction own less than a majority of the voting securities of the surviving corporation; o the commencement of a tender offer for 30% or more of the voting power of our outstanding shares of common stock; o any person coming to own more than 50% of the voting power of our outstanding shares of common stock; or o a change in the composition of our Board of Directors, in which less than two-thirds of its members have been members for two consecutive years.

Our six directors Mark A. Emalfarb, Stephen J. Warner, Richard J. Berman, Robert B. Shapiro, and Harry Z. Rosengart our five board members,and Glenn E. Nedwin, Ph.D. are each parties to indemnification agreements pursuant to which we agreed to indemnify them against any liability arising out of their performance of their duties to us in their capacities as directors.directors (except that Dr. Nedwin’s indemnification agreement is contained in his employment agreement). The agreements with Messrs. Emalfarb and Warner were entered into by Dyadic-Florida on August 19, 2004 and assumed by us incident to the merger. Incident to the consummation of the merger, they were amended to substitute applicable Delaware law for any references contained in those agreements to Florida law. The agreements with Mr. Berman, Mr. Shapiro and Mr. Rosengart were entered into directly with us in 2005 when they became directors. The agreement with Dr. Nedwin was entered into in March 2006 when he became a director. All of these indemnification agreements indemnify our directors in addition to the indemnification provided by our restated certificate of incorporation and amended and restated bylaws. Among other things, these agreements indemnify our directors for certain expenses, including attorneys'attorneys’ fees, judgments, fines and settlement amounts incurred by them in any action or proceeding, including any action by or in the right of Dyadic arising out of such person'sperson’s services to us or to any of our subsidiaries or any other company or enterprise to which such person provides services at our request. Further, we agree to advance expenses they spend as a result of any proceeding against them as to which they could be indemnified. indemnified (subject to an undertaking that they will repay such advances if it is ultimately determined that they are not entitled to indemnification). Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to our directors and executive officers pursuant to our amended and restated certificate of incorporation and amended and restated bylaws, we have been informed that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.
At present, there is no pending litigation or proceeding involving any of our directors where indemnification will be required or permitted, and we are not aware of any threatened litigation or proceeding that may result in a claim for such indemnification.

The 2001 Equity Compensation Plan is not subject to any provision of the Employee Retirement Income Security Act of 1974, as amended, and is not qualified under Section 401(a) of the Internal Revenue Code of 1986, as amended (the “Code”).
Vote Required
The affirmative vote of the holders of a majority of all shares casting votes, either in person by proxy, at the annual meeting is required to approve the Amended and Restated 2001 Equity Compensation Plan effective as of January 1, 2005.
This approval is required (i) for purposes of compliance with certain exclusions from the limitations of Section 162(m) of the Code and (ii) by the applicable rules of the American Stock Exchange. A properly executed proxy marked “abstain” with respect to this proposal will not be voted, although it will be counted for purposes of determining whether there is a quorum. Abstentions and broker non-votes will have the same effect as a vote against this proposal.
Recommendation of the Board
Dyadic’s board of directors unanimously recommends a vote “FOR” this proposal.
Purposes of Adopting the Amended and Restated 2001 Equity Compensation Plan
Reduction in Share Reserve
The board deems it advisable to reduce the share reserve under the Plan for two reasons. First, assuming stockholders approve the 2006 Stock Option Plan under Proposal 3 at the annual meeting, the board intends to use the 2006 Stock Option Plan as the primary (but not exclusive) vehicle to make equity-based awards. Second, the board believes there will be a sufficient number of shares beyond the reserve (as reduced) that will become available again for grant under the Plan from time to time by reason of the expiration, forfeiture, termination and cancellation of unexercised outstanding stock options, as well as the forfeiture of other types of equity awards, such as performance units and restricted stock.

25


Conformance to Requirements of Section 409A of the Code
The board deems it advisable to conform certain provisions of the Plan to the requirements of Section 409A of the Code to avoid certain tax penalties that could be imposed by Section 409A upon plan participants.
Section 409A of the Code (enacted in 2004) requires all amounts deferred under a nonqualified deferred compensation plan, such as the 2001 Equity Compensation Plan, to comply, in form and operation, with rules governing (i) prohibitions on acceleration of benefits, (ii) distributions and (iii) initial and subsequent elections as to the timing of the distribution of benefits. Violation of these rules will cause a participant to recognize deferred compensation on a current basis to the extent it is not subject to substantial risk of forfeiture. Additionally, if a violation of the Section 409A rules occurs, a plan participant is required to pay retroactive interest (the underpayment rate plus 1%) and a 20% penalty. Section 409A of the Code does not apply to amounts earned and vested on or before December 31, 2004. Accordingly, a participant is exempt from the rules of Section 409A of the Code with respect to any deferred compensation that (i) he had a legally binding right to on or before that date and (ii) was not subject to substantial risk of forfeiture on that date. However, because a special rule applies to certain equity-based compensation, including stock options, options that were immediatelyexercisable on or before December 31, 2004 are treated as earned and vested, even if they would terminate upon the participant’s termination of his or her services.
In order to conform certain provisions of the 2001 Equity Compensation Plan with the requirements of Section 409A of the Code, the Amended and Restated 2001 Equity Compensation Plan incorporates certain changes to the following Sections of the Plan:
·  Section 1(b) was amended to comply with the Proposed Treasury Regulations §1.409A (“Prop. Regs.”) and satisfy the good faith compliance standard created by the Prop. Regs.;
·  Section 5(b)(ii) was amended to make mandatory, instead of permissive, the requirement that all stock options have an exercise price of not less than the fair market value of our common stock on the date of the grant of the stock option, which is now fixed as the trading price of our shares as of the close of trading on that date;
·  Section 6(e) was amended to remove a provision providing for the payment of dividends or other distributions paid on such restricted stock grants while they remain subject to forfeiture, in order to comply with the Prop. Regs. and satisfy the good faith compliance standard created by the Prop. Regs.;
·  Section 7, pertaining to “Performance Units,” was amended to comply with the Prop. Regs. and satisfy the good faith compliance standard created by the Prop. Regs.;
·  Section 8, pertaining to “Qualified Performance Based Compensation” (another category of performance-based compensation), was amended to comply with the Prop. Regs. and satisfy the good faith compliance standard created by the Prop. Regs.;
·  Section 9 contains payment deferral provisions that were conformed to the provisions of Section 409A(a)(3) of the Code;
·  the definition of a “Change of Control” set forth in Section 12 has been amended both to conform to a guidance issued under IRS Notice 2005-1 and the Prop. Regs., and to delete a change of control alternative pertaining to the composition of the our board of directors rendered obsolete by our implementation of a classified board;
·  Section 15 was amended to (i) require the compensation committee to act in a manner consistent with the provisions of Section 409A, and (2) provide that no compensation committee action may be taken which would cause the application of the 20% penalty or immediate tax recognition under Section 409A; and
·  a new section 21(c) was added to make null and void any provision in the 2001 Equity Compensation Plan that would have the effect of causing the application of a 20% penalty or immediate tax recognition under Section 409A of the Code.
26

Increase in Individual Annual Limit on Shares Awards Under Section 162(m) of the Code
The board deems it advisable to increase the maximum limitation of shares that may be subject to awards granted under the Plan to any one individual for any fiscal year during the term of the Plan to 1,200,000 shares from 100,000 shares in order to avoid the $1 million compensation deductibility limitation of Section 162(m) of the Code. The board believes it is in the best interests of the Company and its stockholders that the limitations on the deductibility on compensation to named executives imposed by the provisions of Section 162(m) of the Code be avoided. Section 162(m) of the Code generally limits to $1 million the amount that may be deducted as compensation expense (including options and restricted stock awards) paid in one year to a named executive officer. However, an exception to this limitation applies if the compensation is (1) “performance-based compensation,” (2) awarded pursuant to a compensation plan which has received stockholder approval and (3) the plan includes a maximum limitation of shares that may be subject to awards to any one individual for any fiscal year. Since the compensation committee has made awards to two members of senior management that exceed the 2001 Equity Compensation Plan’s annual limitation of 100,000 shares, the Amended and Restated 2001 Equity Compensation Plan increases the annual limitation to 1,200,000 shares effective as of January 1, 2005, so that the awards to such members of senior management will qualify for the exemption from the application of the $1 million compensation deductibility limitation of Section 162(m) of the Code. However, the increased annual limitation will not be effective unless the Amended and Restated 2001 Equity Compensation Plan is approved by stockholders at the annual meeting.
Effectiveness of the Amended and Restated 2001 Equity Compensation Plan
The Amended and Restated 2001 Equity Compensation Plan is effective as of January 1, 2005, subject to stockholder approval.
Summary of Material Provisions of the Amended and Restated 2001 Equity Compensation Plan
The following is a summary of the material provisions of the Amended and Restated 2001 Equity Compensaion Plan. This summary is qualified in its entirety by reference to the Amended and Restated 2001 Equity Compensation Plan, the full text of which is attached as Annex A to this proxy statement. You are urged to read the full text of the Amended and Restated 2001 Equity Compensation Plan, which we refer to as the “2001 Equity Compensation Plan” in this summary.

Plan Administration. The compensation committee of our board of directors serves as the “plan administrator” of the 2001 Equity Compensation Plan. In order to adhere to the rules of the American Stock Exchange, and to assure that awards made thereunder qualify as “performance based compensation” within the meaning of Section 162(m) of the Code, not less than a majority of the members of our compensation committee are “outside directors” within the meaning of Section 162(m) of the Code and “independent directors” within the meaning of the rules of the American Stock Exchange. The compensation committee is authorized to:
·  select persons eligible to receive awards;
·  determine the type and number of awards to be granted and the number of shares underlying the awards;
·  specify times at which such awards will be exercisable (including performance conditions that may be required to be satisfied as a condition to exercisability);
·  set other terms and conditions of awards;
·  prescribe forms of award agreements;
·  interpret and specify rules and regulations relating to the 2001 Equity Compensation Plan; and
·  make all other decisions and determinations as the compensation committee may deem necessary or advisable for the administration of the 2001 Equity Compensation Plan.
Eligibility. All of our and our subsidiaries’ officers, employees, directors, and certain consultant determined by the compensation committee to be “Key Advisors” are eligible to be granted awards under the 2001 Equity Compensation Plan.
27

Types of Awards. The 2001 Equity Compensation Plan provides for the award of a broad variety of share-based compensation alternatives, including: (i) options intended to qualify as incentive stock options (“ISOs”) under Section 422 of the Code, to our employees, (ii) non-statutory stock options (“NSOs,” and together with “ISOs,” collectively, “options”) to our and our subsidiaries’ directors, employees and Key Advisors; (iii) shares of our common stock; (iv) performance units; and (v) qualified performance-based performance units of share awards. The maximum number of shares which may be the subject of an award to any individual in a single year is 1,200,000 shares.

The exercise price for all options may not be less than the closing trading price of our common stock on the date the option is granted, except for ISOs granted to 10% stockholders, which must have an exercise price of not less than 110% of the fair market value of our common stock on the date the option is granted. ISOs have a maximum term of ten years, except for 10% stockholders who are subject to a maximum term of five years. Options are not transferable other than by will and the laws of descent and distribution. Options generally expire not later than 90 days following a termination of employment, 12 months following the optionee’s disability, or not later than 12 months following the optionee’s death. In the administration of the 2001 Equity Compensation Plan, the compensation committee is proscribed from taking any action which would have the effect of causing the provisions of Section 409A of the Code to apply.
The exercise price for an option is payable in (a) cash, (b) with the approval of the compensation committee, by delivering shares of our common stock owned by the optionee (including shares acquired in connection with the exercise of an option) and having a fair market value on the date of exercise equal to the exercise price or to the ownership of shares, have a fair market value on the date of exercise equal to the exercise price (c) payment through a broker in accordance with procedures permitted by Regulation T of the Federal Reserve, or (d) by such other method as the compensation committee may approve.
Each award or option granted under the 2001 Equity Compensation Plan is required to be evidenced by a written agreement between us and the recipient of the award or option. If the Dyadic International, Inc. 2006 Stock Option Plan under Proposal 3 is approved by stockholders at the annual meeting, the compensation committee anticipates limiting awards under the 2001 Equity Compensation Plan principally to shares of restricted stock, as and when the compensation committee determines that such awards are preferable to grants of options (which would otherwise be made under the 2006 Stock Option Plan).
Shares Available for Awards. The 2001 Equity Compensation Plan has 4,478,475 shares reserved for issuance thereunder. If an option expires or is terminated or canceled without having been exercised or settled in full, or in the case of shares, is forfeited back to or repurchased by us, the terminated portion of the option (or forfeited or repurchased shares subject to the award) will become available for future grant or sale under the 2001 Equity Compensation Plan (unless it has terminated). Shares are not deemed to be issued under the 2001 Equity Compensation Plan with respect to any portion of an option that is settled in cash. If the exercise or purchase price of an Option is paid for through the tender of shares, or withholding obligations are met through the tender or withholding of shares, those shares tendered or withheld will again be available for issuance under the 2001 Equity Compensation Plan.
Change in Control. The 2001 Equity Compensation Plan permits the compensation committee, at the time of the grant of an award, to provide in the agreement evidencing that award for any of the following alternatives in the event of a change of control: (i) that a full vesting of all unvested rights occur; (ii) that a grantee holding performance units shall receive a payment in settlement of the performance units in an amount determined by the committee; (iii) that the optionee surrender his or her outstanding options in exchange for a payment by us, in cash or shares as determined by the committee, in an amount equal to the amount by which the then fair market value of the shares subject to the optionee’s unexercised options exceeds the exercise price of the options; or (iv) after affording the grantee of an option an opportunity exercise that option, terminate any or all unexercised options at such time as the committee deems appropriate. The term “change in control” is defined under the 2001 Equity Compensation Plan to mean:
·  a sale of all or substantially all of our assets;
·  a merger or consolidation in which our stockholders immediately prior to the transaction own less than a majority of the voting securities of the surviving corporation;
·  the sale or disposition of assets equal to or greater than 40% of the total gross fair market value of our assets immediately prior to such sale or disposition; or
·  any person (other than our existing stockholders who beneficially own, directly or indirectly, more than 20% of the voting power of our outstanding shares of common stock) coming to own more than 50% of the voting power of our outstanding shares of common stock.
28

Except to the extent an award agreement provides otherwise, if we are not the surviving corporation in a change in control (or survive only as a subsidiary of another corporation), unless the compensation committee determines otherwise, all outstanding options that are not exercised shall be assumed by, or replaced with comparable options or rights by the surviving corporation (or a parent of the surviving corporation), and other outstanding awards shall he converted to similar grants of the surviving corporation (or a parent of the surviving corporation).
Amendment and Termination. The 2001 Equity Compensation Plan may be amended or terminated at any time by our board of directors, except that no amendment may be made without stockholder approval if such approval is necessary to comply with any tax or regulatory requirement.
Federal Income Tax Consequences
The following discussion of certain relevant federal income tax consequences applicable to stock options granted under the 2001 Equity Compensation Plan is a brief summary only, and reference is made to the Code and the regulations and interpretations issued thereunder for a complete statement of all relevant federal tax consequences. This summary is not intended to be exhaustive and does not address state, local or foreign tax consequences.
Incentive Stock Options. ISOs are intended to be eligible for the favorable federal income tax treatment accorded “incentive stock options” under the Code. There generally are no federal income tax consequences to the optionee or the Company by reason of the grant or exercise of an ISO. However, the exercise of ISOs may increase the optionee’s alternative minimum tax liability, if any.
If an optionee holds stock acquired through exercise of an ISO for at least two years from the date on which the Option is granted and at least one year from the date on which the shares are transferred to the optionee upon exercise of the option, any gain or loss on a disposition of such stock will be long-term capital gain or loss. Generally, if the optionee disposes of the stock before the expiration of either of these holding periods (a “disqualifying disposition”), at the time of disposition, the optionee will realize taxable ordinary income equal to the lesser of (a) the excess of the stock’s fair market value on the date of exercise over the exercise price, or (b) the optionee’s actual gain, if any, on the purchase and sale. The optionee’s additional gain, or any loss, upon the disqualifying disposition will be a capital gain or loss. Capital gains currently are generally subject to lower tax rates than ordinary income. Slightly different rules may apply to optionees who acquire stock subject to certain repurchase options.
To the extent the optionee recognizes ordinary income by reason of a disqualifying disposition, we will generally be entitled (subject to the requirement of reasonableness and the satisfaction of a tax reporting obligation) to a corresponding business expense deduction in the tax year in which the disqualifying disposition occurs.
Non-Statutory Stock Options. Generally, there are no tax consequences to the optionee or us by reason of the grant of an NSO. Upon exercise of an NSO, the optionee normally will recognize taxable ordinary income equal to the excess of the stock’s fair market value on the date of exercise over the option exercise price. Generally, with respect to employees, the Company is required to withhold payroll and income taxes from regular wages or supplemental wage payments in an amount based on the ordinary income recognized. Subject to the requirement of reasonableness and the satisfaction of a reporting obligation, we will generally be entitled to a business expense deduction equal to the taxable ordinary income realized by the optionee. Upon disposition of the stock, the optionee will recognize a capital gain or loss equal to the difference between the selling price and the purchase price (to the extent not recognized as taxable income as described above). Slightly different rules may apply to optionees who acquire stock subject to certain repurchase options or who are subject to Section 16(b) of the Securities Exchange Act of 1934, as amended.
Stock Awards. Where the award has no vesting, the grantee will recognize taxable ordinary income equal to the stock’s fair market on the date of grant. For an award subject to vesting, the grantee will normally recognize taxable ordinary income equal to the excess, if any, of the stock’s fair market on the date of stock vests over the purchase price paid for the shares, if any. To the extent that the grantee files a “Section 83(b) election” pursuant to Section 83(b) of the Code, the grantee will recognize ordinary taxable income at the time of the receipt or purchase of the shares of stock equal to the fair market of the stock on the date of receipt or purchase less the amount, if any, paid by the grantee for the stock. With respect to our employees, we generally are required to withhold an amount based on ordinary income recognized. Generally, we will be entitled to an income tax deduction equal to the amount of taxable ordinary income recognized by the grantee of the award.
Performance Units and Qualified Performance-Based Compensation. The designation of an award as performance units or as qualified Performance-Based Compensation will not change the tax treatment described above with respect to stock awards.
Options Outstanding under the Amended and Restated 2001 Equity Compensation Plan
As of April 26, 2006, options granted under the 2001 Equity Compensation Plan to purchase (i) an aggregate of 3,032,944 shares of common stock were outstanding to approximately 90 employees and consultants (ii) 225,417 shares of common stock were outstanding to non-employee directors. The options were granted at exercise prices ranging from $1.83 to $7.13 per share.
On April 26, 2006, the last reported sale price per share of Dyadic common stock on the American Stock Exchange was $5.84.
The table below indicates, as of April 26, 2006, the aggregate number of options outstanding under the 2001 Equity Compensation Plan to each of our named executive officers and directors and the groups indicated. There are no stock awards or performance units outstanding under the 2001 Equity Compensation Plan other than as described in footnotes 2 and 3 to the table and the issuance of 7,476 shares of common stock in July 2004 to certain employees of Dyadic-Florida for a payment of a portion of accrued bonuses.

PROPOSAL 3: APPROVAL OF 2006 STOCK OPTION PLAN
On April 19, 2006, the board of directors adopted the Dyadic International, Inc. 2006 Stock Option Plan. The purpose of the 2006 Stock Option Plan is to retain and attract key management, employees, nonemployee directors and consultants by providing those persons with a proprietary interest in us. At the annual meeting, stockholders will be asked to approve the 2006 Stock Option Plan.
Our board of directors adopted the 2006 Stock Option Plan, subject to stockholder approval, because it believes that it is in the best interests of us and our stockholders that we rely principally upon the issuance of stock options at exercise prices of not less than the price of the underlying shares on the date of grant (discussed further below) as our primary equity compensation vehicle, and that the plan administrator of the plan, the compensation committee of the board of directors be afforded the greatest amount of discretion in administering the 2006 Stock Option Plan as is permitted by applicable income tax laws.
There are currently no outstanding options under the 2006 Stock Option Plan.
The 2006 Stock Option Plan is not subject to any provision of the Employee Retirement Income Security Act of 1974, as amended, and is not qualified under Section 401(a) of the Code.
Vote Required
The affirmative vote of the holders of a majority of all shares casting votes, either in person by proxy, at the annual meeting is required to approve the 2006 Stock Option Plan.
This approval is required (i) for purposes of compliance with certain exclusions from the limitations of Section 162(m) of the Code, (ii) for purposes of compliance with the requirements of incentive stock options under Section 422 of the Code, and (iii) by the applicable rules of the American Stock Exchange. A properly executed proxy marked “abstain” with respect to this proposal will not be voted, although it will be counted for purposes of determining whether there is a quorum. Abstentions and broker non-votes will have the same effect as a vote against this proposal.
Recommendation of the Board
Dyadic’s board of directors unanimously recommends a vote “FOR” this proposal.
Summary of Material Provisions of the 2006 Stock Option Plan
The following is a summary of the material provisions of the 2006 Stock Option Plan. This summary is qualified in its entirety by reference to the 2006 Stock Option Plan, the full text of which is attached as Annex B to this proxy statement. You are urged to read the full text of the 2006 Stock Option Plan, which we refer to as the “Option Plan” in this summary.
Plan Administration. The compensation committee of our board of directors will serve as the “plan administrator” of the Option Plan. In order to adhere to the rules of the American Stock Exchange, and to assure that awards made thereunder qualify as “performance based compensation” within the meaning of Section 162(m) of the Code, not less than a majority of the members of our compensation committee are “outside directors” within the meaning of Section 162(m) of the Code and “independent directors” within the mean of the rules of the American Stock Exchange. The compensation committee is authorized to:
·  select persons eligible to receive awards of options;
·  determine the type of option and number of shares as to which the option relates;
·  specify times at which such options will be exercisable (including performance conditions that may be required to be satisfied as a condition to exercisability);
·  set other terms and conditions of option awards;
31

·  prescribe forms of option award agreements;
·  interpret and specify rules and regulations relating to the Option Plan; and
·  make all other decisions and determinations as the compensation committee may deem necessary or advisable for the administration of the 2006 Option Plan.
Eligibility. All of our and our subsidiaries’ officers, employees and directors, and certain consultants determined by the compensation committee to be “Key Advisors” are eligible to be granted options under the Option Plan.
Types of Options. The 2006 Option Plan provides for the grant of options intended to qualify as incentive stock options (“ISOs”) under Section 422 of the Code, to employees of us and our subsidiaries and non-statutory stock options (“NSOs,” and together with “ISOs,” collectively, “options”) to directors, employees and Key Advisors to us and our subsidiaries.
Exercise Prices and Exercisability. The exercise price for options cannot be less than the closing trading price of our common stock on the date the option is granted, except for ISOs granted to 10% stockholders, which must have an exercise price of not less than 110% of the closing trading price of our common stock on the date the option is granted. ISOs have a maximum term of ten years, except for 10% stockholders who are subject to a maximum term of five years. Options are not transferable other than by will and the laws of descent and distribution. Options generally expire not later than 90 days following a termination of employment, 12 months following the optionee’s disability, or not later than 12 months following the optionee’s death. In the administration of the Option Plan, the compensation committee is proscribed from taking any action which would have the effect of causing the provisions of Section 409A of the Code to apply.
Options shall vest and become exercisable as determined by the Committee. The exercise price for an option is payable in (a) cash, (b) with the approval of the compensation committee, by delivering shares of our common stock owned by the optionee (including shares acquired in connection with the exercise of an option) and having a fair market value on the date of exercise equal to the exercise price or to the ownership of shares have a fair market value on the date of exercise equal to the exercise price (c) payment through a broker in accordance with procedures permitted by Regulation T of the Federal Reserve, or (d) by such other method as the compensation committee may approve.
If a participant’s employment or relationship with us is terminated, the participant (or his or her designated beneficiary or estate representative in the case of death) may exercise his or her option within such period of time as is specified in the option agreement to the extent that the option is vested on the date of termination. In the absence of a specified time in the option agreement, the option will remain exercisable for three months following the date of termination, except in the case where termination is as a result of disability or death, in which case the option will remain exercisable for 12 months following the date of termination or death.
Shares Available For Option Grants. Subject to adjustment as provided below, there are 2,700,000 shares of our common stock reserved for issuance under the Option Plan. The maximum number of shares which may be the subject of an option grant to any individual in a single year is 1,200,000 shares. If an option expires or is terminated or canceled without having been exercised or settled in full, the terminated portion of the option will become available for future grant under the Option Plan (unless the Option Plan has been terminated). If the exercise or purchase price of an option is paid for through the tender of shares, or withholding obligations are met through the tender or withholding of shares, those shares tendered or withheld will again be available for issuance under the Option Plan.
Amendment and Termination of the Option Plan. The Option Plan will automatically terminate in 2016. In addition, the Option Plan may be amended or terminated by our board of directors, except that no amendment maybe made without stockholder approval if such approval is necessary to comply with any tax or regulatory requirement.

32

Change in Control. The compensation committee enjoys discretion with respect to the treatment of outstanding options upon the occurrence of a “Change in Control.” The term “Change in Control” is defined under the Option Plan to mean:
·  a sale of all or substantially all of our assets or our liquidation or dissolution;
·  a merger or consolidation in which our stockholders immediately prior to the transaction own less than a majority of the voting securities of the surviving corporation;
·  the sale or disposition of assets equal to or greater than 40% of the total gross fair market value of the assets of the Company immediately prior to such sale or disposition; or
·  any person (other than our existing stockholders who beneficially own, directly or indirectly, more than 20% of the voting power of our outstanding shares of common stock) coming to own more than 50% of the voting power of our outstanding shares of common stock.
If we are not the surviving corporation in a change in control (or survive only as a subsidiary of another corporation), unless the compensation committee determines otherwise, all outstanding options that are not exercised shall be assumed by, or replaced with comparable options or rights by the surviving corporation (or a parent of the surviving corporation). However, the compensation committee may, instead take any of the following alternative courses of action at that time:
·  determine that outstanding options shall automatically accelerate and become fully exercisable;
·  require that optionees surrender their outstanding options in exchange for a payment by us, in cash or shares as determined by the committee, in an amount equal to the amount by which the then fair market value of our shares subject to the optionee’s unexercised options exceeds the exercise price of the options; or
·  after giving optionees an opportunity to exercise their outstanding options, terminate any or all unexercised options at such time as the committee deems appropriate.
Federal Income Tax Consequences
The following discussion of certain relevant federal income tax consequences applicable to stock options granted under the Option Plan is a brief summary only, and reference is made to the Code and the regulations and interpretations issued thereunder for a complete statement of all relevant federal tax consequences. This summary is not intended to be exhaustive and does not address state, local or foreign tax consequences.
Inapplicability of Section 409A. Section 409A of the Code will not apply to the Option Plan because by its terms, no options granted under the Option Plan will provide for the deferral of compensation (i.e., each option grant will meet the following three conditions: (i) the exercise price is required to be not less than the fair market value of the underlying shares of our common stock on the grant date; (ii) the number of shares subject to the option are required to be fixed on the date of grant; and (iii) the option cannot include any feature for the deferral of compensation).
Incentive Stock Options. ISOs are intended to be eligible for the favorable federal income tax treatment accorded “incentive stock options” under the Code. There generally are no federal income tax consequences to the optionee or the Company by reason of the grant or exercise of an ISO. However, the exercise of ISOs may increase the optionee’s alternative minimum tax liability, if any.

If an optionee holds stock acquired through exercise of an ISO for at least two years from the date on which the Option is granted and at least one year from the date on which the shares are transferred to the optionee upon exercise of the option, any gain or loss on a disposition of such stock will be long-term capital gain or loss. Generally, if the optionee disposes of the stock before the expiration of either of these holding periods (a “disqualifying disposition”), at the time of disposition, the optionee will realize taxable ordinary income equal to the lesser of (a) the excess of the stock’s fair market value on the date of exercise over the exercise price, or (b) the optionee’s actual gain, if any, on the purchase and sale. The optionee’s additional gain, or any loss, upon the disqualifying disposition will be a capital gain or loss. Capital gains currently are generally subject to lower tax rates than ordinary income. Slightly different rules may apply to optionees who acquire stock subject to certain repurchase options.
To the extent the optionee recognizes ordinary income by reason of a disqualifying disposition, we will generally be entitled (subject to the requirement of reasonableness and the satisfaction of a tax reporting obligation) to a corresponding business expense deduction in the tax year in which the disqualifying disposition occurs.
Non-Statutory Stock Options. Generally, there are no tax consequences to the optionee or us by reason of the grant of an NSO. Upon exercise of an NSO, the optionee normally will recognize taxable ordinary income equal to the excess of the stock’s fair market value on the date of exercise over the option exercise price. Generally, with respect to employees, the Company is required to withhold payroll and income taxes from regular wages or supplemental wage payments in an amount based on the ordinary income recognized. Subject to the requirement of reasonableness and the satisfaction of a reporting obligation, we will generally be entitled to a business expense deduction equal to the taxable ordinary income realized by the optionee. Upon disposition of the stock, the optionee will recognize a capital gain or loss equal to the difference between the selling price and the purchase price (to the extent not recognized as taxable income as described above). Slightly different rules may apply to optionees who acquire stock subject to certain repurchase options or who are subject to Section 16(b) of the Securities Exchange Act of 1934, as amended.

PROPOSAL 4: RATIFICATION OF APPOINTMENT OF
INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
By reason of the reverse merger of us and Dyadic-Florida consummated in October 2004, the historical financial statements of Dyadic-Florida have become the historical financial statements of us. Ernst & Young LLP had been the independent registered public accounting firm of our wholly-owned subsidiary Dyadic-Florida before the merger and has since been our independent registered public accounting firm.
Ernst & Young LLP audited our consolidated financial statements for the year ended December 31, 2005. We had no disagreements with Ernst & Young LLP on accounting and financial disclosures. The audit committee has appointed Ernst & Young LLP to serve as our independent registered public accounting firm for the year ending December 31, 2006.
We are not required to submit the appointment of our independent registered public accounting firm to a vote of our stockholders for ratification. However, the audit committee has recommended that our board submit this matter to stockholders as a matter of good corporate practice, which our board is doing. If stockholders fail to ratify the appointment, the audit committee will reconsider whether to retain Ernst & Young LLP, and may retain that firm or another without re-submitting the matter to our stockholders. Even if our stockholders ratify the appointment, the audit committee may, in its discretion, direct the appointment of a different independent registered public accounting firm at any time during the year if it determines that such a change would be advisable and in the best interests of us and our stockholders.
We expect representatives of Ernst & Young LLP to be present at the annual meeting. They will have the opportunity to make a statement if they desire to do so, and we expect them to be available to respond to appropriate questions.
Vote Required
The affirmative vote of the holders of a majority of all shares casting votes, either in person or by proxy, at the annual meeting is required to ratify the appointment of Ernst & Young LLP as our independent registered public accounting firm for the year ending December 31, 2006.
Recommendation of the Board
Dyadic’s board of directors unanimously recommends a vote “FOR” this proposal.
Audit and Non-Audit Fees
Audit Fees
For the year ended December 31, 2005, Ernst & Young LLP billed us $398,179 in the aggregate for professional services rendered for the audit of our consolidated statements, reviews of the financial statements included in our Quarterly Reports on Form 10-Q for the quarterly period ended March 31, June 30 and September 30, and the review of our registration statement on Form S-3 (formerly a registration statement on Form SB-2).
For the year ended December 31, 2004, Ernst & Young LLP billed us $709,977 in the aggregate for professional services rendered for the audit of our consolidated statements, reviews of the financial statements included in our Quarterly Reports on Form 10-Q for the quarterly period ended March 31, June 30 and September 30, and the review of our registration statement on Form SB-2.

35


Audit-Related Fees
For the years ended December 31, 2005 and 2004, Ernst & Young LLP did not bill us for audit-related fees, as no audit-related fees were performed by them during such years.
Tax Fees
For the years ended December 31, 2005 and 2004, Ernst & Young LLP did not bill us for tax fees, as no tax services were performed by them during such years.
All Other Fees
For the years ended December 31, 2005 and 2004, Ernst & Young LLP did not bill us for other services, as no other services were by performed by them during such years.
The audit committee has determined that the provision of services by the auditors reported hereunder had no impact on either of their independence.
Audit Committee’s Pre-Approval Policies and Procedures
Consistent with SEC policies regarding auditor independence, the audit committee is responsible for appointing, setting compensation and overseeing the work of the independent registered public accounting firm. In recognition of this responsibility, the audit committee has established a policy to pre-approve all audit and permissible non-audit services provided by the independent registered public accounting firm.
Prior to engagement of the independent registered public accounting firm for the next year’s audit, management will submit to the audit committee for approval an aggregate of services expected to be rendered during that year for each of the four categories of services. Prior to engagement, the audit committee pre-approves these services by category of service. The fees are budgeted, and the audit committee requires the independent registered public accounting firm and management to report actual fees versus the budget periodically throughout the year by category of service. During the year, circumstances may arise when it may become necessary to engage the independent registered public accounting firm for additional services not contemplated in the original pre-approval. In those instances, the audit committee requires specific pre-approval before engaging the independent registered public accounting firm.
The audit committee may delegate pre-approval authority to one or more of its members. The member to whom such authority is delegated must report, for informational purposes only, any pre-approval decisions to the audit committee at its next scheduled meeting.
MISCELLANEOUS
Section 16(a) Beneficial Ownership Reporting Compliance
Section 16(a) of the Securities Exchange Act of 1934 requires that our directors and executive officers, and persons who own more than 10 percent of our common stock, to file with the Securities and Exchange Commission initial reports of ownership and reports of changes in ownership of common stock. Officers, directors and greater than 10 percent stockholders are required by SEC regulation to furnish us with all Section 16 reports they file.
To our knowledge, based solely on a review of the copies of such reports furnished to us and representations that no other reports were required, we believe that all Section 16 filing requirements applicable to our officers, directors and 10 percent beneficial owners were complied with during the year ended December 31, 2005, other than a late filing for Form 4 in December 2005 by director Stephen J. Warner for sales of our common stock in November and December 2005.

Annual Report on Form 10-KSB
We have mailed copies of our 2005 annual report with this proxy statement to holders of shares of our common stock as of the record date. We will provide without charge, to each holder of shares of common stock as of the record date, a copy of our Annual Report on Form 10-KSB for the year ended December 31, 2005, as filed with the SEC, upon the written request of any such holder addressed to the Secretary of Dyadic at 140 Intracoastal Pointe Drive, Suite 404, Jupiter, Florida 33477. We will provide copies of any exhibit to the Annual Report on Form 10-KSB upon written request and upon reimbursement of any reasonable expenses incurred by us in furnishing the exhibit.
Stockholder Proposals
Pursuant to Rule 14a-8 under the Securities Exchange Act of 1934, some stockholder proposals may be eligible for inclusion in our proxy statement for our 2007 annual meeting of stockholders. To be eligible for inclusion in our 2007 proxy statement, any such proposals must be delivered in writing to the Secretary of Dyadic no later than December 28, 2006, and must meet the requirements of Rule 14a-8 under the Securities Exchange Act of 1934. The submission of a stockholder proposal does not guarantee that it will be included in our proxy statement.
Stockholders who do not wish to follow the SEC rules in proposing a matter for action at the 2007 annual meeting of stockholders must notify Dyadic in writing of the information required by Dyadic’s amended and restated bylaws dealing with stockholder proposals. The notice must be delivered to Dyadic’s Secretary not later than the close of business on March 14, 2007 nor earlier than February 12, 2007.
Other Matters
As of the date of this proxy statement, our board of directors does not know of any other matters that will be presented for consideration at the annual meeting other than as described in this proxy statement. If, however, any other matters are properly brought before the annual meeting, it is intended that the persons named as proxies will vote in accordance with their best judgment with respect to such matters.

ANNEX A
DYADIC INTERNATIONAL, INC.
2001 EQUITY COMPENSATION PLAN
As Amended and Restated Effective January 1, 2005
RECITALS:
WHEREAS, effective as of May 22, 2001, the Company adopted the Dyadic International, Inc. 2001 Equity Compensation Plan (the “Plan”) to provide (i) designated employees of the Company and its subsidiaries, (ii) certain consultants and advisors who perform services for the Company or its subsidiaries and (iii) non-employee members of the Board of Directors of the Company (the “Board”), with the opportunity to receive grants of incentive stock options, nonqualified stock options, stock awards and performance units; and
WHEREAS, the Company believed that the Plan would encourage the participants to contribute materially to the growth of the Company, thereby benefiting the Company’s shareholders, and would align the economic interests of the participants with those of the shareholders; and
WHEREAS, section 409A of the Internal Revenue Code of 1986, as amended (the “Code”), as added by the American Jobs Creation Act of 2004, made certain changes to the rules applicable to amounts deferred under nonqualified deferred compensation plans on or after January 1, 2005; and
WHEREAS, the Company now wishes to amend and restate the Plan effective January 1, 2005, to comply with section 409A of the Code, and to make certain other changes to the Plan.
NOW, THEREFORE, the Company hereby amends and restates the Plan in its entirety to read as follows:
1.Administration.
(a)Committee. The Plan shall be administered by a committee appointed by the Board (the “Committee”, which may consist of two or more persons who are “outside directors” as defined under section 162(m) of the Code, and related Treasury regulations and “non-employee directors” as defined under Rule 16b-3 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). However, the Board may ratify or approve any grants as it deems appropriate.
(b)Committee Authority. The Committee shall have the sole authority to (i) determine the individuals to whom grants shall be made under the Plan, (ii) determine the type, size and terms of the grants to be made to each such individual, (iii) determine the time when the grants will be made and the duration of any applicable exercise or restriction period, including the criteria for exercisability and the acceleration of exercisability, (iv) amend the terms of any previously issued grant, and (v) deal with any other matters arising under the Plan. Notwithstanding the authority granted to the Committee in (iii) and (iv) above, the Plan shall prohibit the acceleration of the time or schedule of any payment of deferred compensation, except to the extent permitted under section 409A of the Code and the Treasury regulations thereunder.

A-1


(c)Committee Determinations. The Committee shall have full power and authority to administer and interpret the Plan, to make factual determinations and to adopt or amend such rules, regulations, agreements and instruments for implementing the Plan and for the conduct of its business as it deems necessary or advisable, in its sole discretion. The Committee’s interpretations of the Plan and all determinations made by the Committee pursuant to the powers vested in it hereunder shall be conclusive and binding on all persons having any interest in the Plan or in any awards granted hereunder. All powers of the Committee shall be executed in its sole discretion, in the best interest of the Company, not as a fiduciary, and in keeping with the objectives of the Plan and need not be uniform as to similarly situated individuals.
2.Grants.
Awards under the Plan may consist of grants of incentive stock options as described in Section 5 (“Incentive Stock Options”), nonqualified stock options as described in Section 5 (“Nonqualified Stock Options”), Incentive Stock Options and Nonqualified Stock Options are collectively referred to as “Options,” stock awards as described in Section 6 (“Stock Awards”), and performance units as described in Section 7 (“Performance Units”) (hereinafter collectively referred to as “Grants”). All Grants shall be subject to the terms and conditions set forth herein and to such other terms and conditions consistent with this Plan as the Committee deems appropriate and as are specified in writing by the Committee to the individual in a grant instrument or an amendment to the grant instrument (the “Grant Instrument”). The Committee shall approve the form and provisions of each Grant Instrument. Grants under a particular Section of the Plan need not be uniform as among the grantees.
3.Shares Subject to the Plan.
(a)Shares Authorized. Subject to adjustment as described below, the aggregate number of shares of common stock of the Company (“Company Stock”) that may be issued or transferred under the Plan is 4,478,475 shares. The maximum aggregate number of shares of Company Stock that shall be subject to Grants made under the Plan to any individual during any calendar year shall be 1,200,000 shares, subject to adjustment as described below. The shares may be authorized but unissued shares of Company Stock or reacquired shares of Company Stock, including shares purchased by the Company on the open market for purposes of the Plan. If and to the extent Options granted under the Plan terminate, expire, or are canceled, forfeited, exchanged or surrendered without having been exercised or if any Stock Awards or Performance Units are forfeited, the shares subject to such Grants shall again be available for purposes of the Plan.
(b)Adjustments. If there is any change in the number or kind of shares of Company Stock outstanding (1) by reason of a stock dividend, spinoff, recapitalization, stock split, or combination or exchange of shares, (ii) by reason of a merger, reorganization or consolidation in which the Company is the surviving corporation, (iii) by reason of a reclassification or change in par value, or (iv) by reason of any other extraordinary or unusual event affecting the outstanding Company Stock as a class without the Company’s receipt of consideration, or if the value of outstanding shares of Company Stock is substantially reduced as a result of a spinoff or the Company’s payment of an extraordinary dividend or distribution, the maximum number of shares of Company Stock available for Grants, the maximum number of shares of Company Stock that any individual participating in the Plan may be panted in any year, the number of shares covered by outstanding Grants, the kind of shares issued under the Plan, and the price per share or the applicable market value of such Grants may be appropriately adjusted by the Committee to reflect any increase or decrease in the number of, or change in the kind or value of, issued shares of Company Stock to preclude, to the extent practicable, the enlargement or dilution of rights and benefits under such Grants; provided, however, that any fractional shares resulting from such adjustment shall be eliminated. Any adjustments determined by the Committee shall be final, binding and conclusive.
4.Eligibility for Participation.
(a)Eligible Persons. All employees of the Company and its subsidiaries (“Employees”), including Employees who are officers or members of the Board, and members of the Board who are not Employees (“Non-Employee Directors”) shall be eligible to participate in the Plan. Consultants and advisors who perform services for the Company or any of its subsidiaries (“Key Advisors”) shall be eligible to participate in the Plan if the Key Advisors render bona fide services to the Company or its subsidiaries, the services are not in connection with the offer and sale of securities in a capital-raising transaction and the Key Advisors do not directly or indirectly promote or maintain a

A-2


 market for the Company’s securities.
(b)Selection of Grantees. The Committee shall select the Employees, Non-Employee Directors and Key Advisors to receive Grants and shall determine the number of shares of Company Stock subject to a particular Grant in such manner as the Committee determines. Employees, Key Advisors and Non-Employee Directors who receive Grants under this Plan shall hereinafter be referred to as “Grantees.”
5.Granting of Options.
(a)Number of Shares. The Committee shall determine the number of shares of Company Stock that will be subject to each Grant of Options to Employees, Non-Employee Directors and Key Advisors.
(b)Type of Option and Price.
(i)The Committee may grant Incentive Stock Options that are intended to qualify as “incentive stock options” within the meaning of section 422 of the Code or Nonqualified Stock Options that are not intended so to qualify or any combination of Incentive Stock Options and Nonqualified Stock Options, all in accordance with the terms and conditions set forth herein. Incentive Stock Options may be granted only to Employees. Nonqualified Stock Options may be granted to Employees, Non-Employee Directors and Key Advisors.
(ii)The purchase price (the “Exercise Price”) of Company Stock subject to an Option shall be determined by the Committee and shall be equal to or greater than the Fair Market Value (as defined below) of a share of Company Stock on the date the Option is granted; provided, however, that an Incentive Stock Option may not be granted to an Employee who, at the time of grant, owns stock possessing more than ten percent (10%) of the total combined voting power of all classes of stock of the Company or any parent or subsidiary of the Company, unless the Exercise Price per share is not less than one hundred ten percent (110%) of the Fair Market Value of Company Stock on the date of grant.
(iii)If the Company Stock is publicly traded, then the Fair Market Value per share shall be determined as follows: (x) if the principal trading market for the Company Stock is a national securities exchange or the Nasdaq National Market, the last reported sale price thereof on the relevant date or (if there were no trades on that date) the latest preceding date upon which a sale was reported or (y) if the Company Stock is not principally traded on such exchange or market, the mean between the last reported “bid” and “asked” prices of Company Stock on the relevant date, as reported on Nasdaq or, if not so reported, as reported by the National Daily Quotation Bureau, Inc. or as reported in a customary financial reporting service, as applicable and as the Committee determines. If the Company Stock is not publicly traded or, if publicly traded, is not subject to reported transactions or “bid” or “asked” quotations as set forth above, the Fair Market Value per share shall be as determined by the Committee.
(c)Option Term. The Committee shall determine the term of each Option. The term of any Option shall not exceed ten years from the date of grant. However, an Incentive Stock Option that is granted to an Employee who, at the time of grant owns stock possessing more than ten percent (10%) of the total combined voting power of all classes of stock of the Company, or any parent or subsidiary of the Company, may not have a term that exceeds five years from the date of grant.
(d)Exercisability of Options. Options shall become exercisable in accordance with such terms and conditions, consistent with the Plan, as may be determined by the Committee and specified in the Grant Instrument. The Committee may waive or accelerate the satisfaction of an exercise term or condition of any or all outstanding Options at any time for any reason in the event the Exercise Price was equal to or greater than the Fair Market Value of the underlying shares of Company Stock on the date of grant, to the extent permitted under section 409A of the Code and the Treasury regulations thereunder.
(e)Termination of Employment, Disability or Death.

A-3


       (i)Except as provided below, an Option may only be exercised while the Grantee is employed by, or providing service to, the Company as an Employee, Key Advisor or member of the Board. In the event that a Grantee ceases to be employed by, or provide service to, the Company for any reason other than Disability, death, or termination for Cause (as defined below), any Option which is otherwise exercisable by the Grantee shall terminate unless exercised within 90 days after the date on which the Grantee ceases to be employed by, or provide service to, the Company (or within such, other period of time as may be specified by the Committee), but in any event no later than the date of expiration of the Option term. Except as otherwise provided by the Committee any of the Grantee’s Options that are not otherwise exercisable as of the date on which the Grantee ceases to be employed by, or provide service to, the Company shall terminate as of such date.
(ii)In the event the Grantee ceases to be employed by, or provide service to, the Company on account of a termination for Cause by the Company, any Option held by the Grantee shall terminate as of the date the Grantee ceases to be employed by, or provide service to, the Company. In addition, notwithstanding any other provisions of this Section 5, if the Committee determines that the Grantee has engaged in conduct that constitutes Cause at any time while the Grantee is employed by, or providing service to, the Company or after the Grantee’s termination of employment or service, any Option held by the Grantee shall immediately terminate and the Grantee shall automatically forfeit all shares underlying any exercised portion of an Option for which the Company has not yet delivered the share certificates, upon refund by the Company of the Exercise Price paid by the Grantee for such shares. Upon any exercise of an Option, the Company may withhold delivery of share certificates pending resolution of an inquiry that could lead to a finding resulting in a forfeiture.
(iii)In the event the Grantee ceases to be employed by, or provide service to, the Company because the Grantee is Disabled, any Option which is otherwise exercisable by the Grantee shall terminate unless exercised within one year after the date on which the Grantee ceases to be employed by, or provide service to, the Company (or within such other period of time as may be specified by the Committee), but in any event no later than the date of expiration of the Option term.
Except as otherwise provided by the Committee, any of the Grantee’s Options which are not otherwise exercisable as of the date on which the Grantee ceases to be employed by, or provide service to, the Company shall terminate as of such date.
(iv)If the Grantee dies while employed by, or providing service to, the Company or within 90 days after the date on which the Grantee ceases to be employed or provide service on account of a termination specified in Section 5(e)(i) above (or within such other period of time as may be specified by the Committee), any Option that is otherwise exercisable by the Grantee shall terminate unless exercised within one year after the date on which the Grantee ceases to be employed by, or provide service to, the Company (or within such other period of time as may be specified by the Committee), but in any event no later than the date of expiration of the Option term. Except as otherwise provided by the Committee, any of the Grantee’s Options that are not otherwise exercisable as of the date on which the Grantee ceases to be employed by, or provide service to, the Company shall terminate as of such date.
(v)For purposes of this Section 5(e), and Sections 6 and 7:
(A)The term “Company” shall mean the Company and its parent and subsidiary corporations or other entities, as determined by the Committee.
                                (B)“Employed by, or provide service to, the Company” shall mean employment or service as an Employee, Key Advisor or member of the Board (so that, for purposes of exercising Options and satisfying conditions with respect to Stock Awards and Performance Units, a Grantee shall not be considered to have terminated employment or service until the Grantee ceases to be an Employee, Key Advisor and member of the Board), unless the Committee determines otherwise.
                                (C)“Disability” shall mean a Grantee’s becoming disabled within the meaning of section 22(e)(3) of the Code.

A-4



(D)“Cause” shall mean, except to the extent specified otherwise by the Committee, a finding by the Committee that the Grantee (i) has breached his or her employment or service contract with the Company, (ii) has engaged in disloyalty to the Company, including, without limitation, fraud, embezzlement, theft, commission of a felony or proven dishonesty in the course of his or her employment or service, (iii) has disclosed trade secrets or confidential information of the Company to persons not entitled to receive such information or (iv) has engaged in such other behavior detrimental to the interests of the Company as the Committee determines.
(f)Exercise of Options. A Grantee may exercise an Option that has become exercisable, in whole or in part, by delivering a notice of exercise to the Company with payment of the Exercise Price. The Grantee shall pay the Exercise Price for an Option as specified by the Committee (w) in cash, (x) with the approval of the Committee, by delivering shares of Company Stock owned by the Grantee (including Company Stock acquired in connection with the exercise of an Option, subject to such restrictions as the Committee deems appropriate) and having a Fair Market Value on the date of exercise equal to the Exercise Price or by attestation (on a form prescribed by the Committee) to ownership of shares of Company Stock having a Fair Market Value on the date of exercise equal to the Exercise Price, (y) pay through a broker in accordance with procedures permitted by Regulation T of the Federal Reserve Board, or (z) by such other method as the Committee may approve. The Committee may authorize loans by the Company to Grantees in connection with the exercise of an Option, upon such terms and conditions as the Committee, in its sole discretion, deems appropriate. Shares of Company Stock used to exercise an Option shall have been held by the Grantee for the requisite period of time to avoid adverse accounting consequences to the Company with respect to the Option. The Grantee shall pay the Exercise Price and the amount of any withholding tax due at the time of exercise.
(g)Limits on Incentive Stock Options. Each Incentive Stock Option shall provide that, if the aggregate Fair Market Value of the stock on the date of the grant with respect to which Incentive Stock Options are exercisable for the first time by a Grantee during any calendar year, under the Plan or any other stock option plan of the Company or a parent or subsidiary, exceeds $100,000, then the Option, as to the excess, shall be treated as a Nonqualified Stock Option. An Incentive Stock Option shall not be granted to any person who is not an Employee of the Company or a parent or subsidiary (within the meaning of section 424(f) of the Code).
6.Stock Awards.
The Committee may issue or transfer shares of Company Stock to an Employee, non-Employee Director or Key Advisor under a Stock Award, upon such terms as the Committee deems appropriate. The following provisions are applicable to Stock Awards:
(a)General Requirements. Shares of Company Stock issued or transferred pursuant to Stock Awards may be issued or transferred for consideration or for no consideration, and subject to restrictions or no restrictions, as determined by the Committee. The Committee may, but shall not be required to, establish conditions under which restrictions on Stock Awards shall lapse over a period of time or according to such other criteria as the Committee deems appropriate, including, without limitation, restrictions based upon the achievement of specific performance goals. The period of time during which the Stock Awards will remain subject to restrictions will be designated in the Grant Instrument as the “Restriction Period.”
(b)Number of Shares. The Committee shall determine the number of shares of Company Stock to be issued or transferred pursuant to a Stock Award and the restrictions applicable to such shares.
(c)Requirement of Employment or Services. If the Grantee ceases to be employed by, or provide service to, the Company (as defined in Section 5(e)) during a period designated in the Grant Instrument as the Restriction Period, or if other specified conditions are not met, the Stock Award shall terminate as to all shares covered by the Grant as to which the restrictions have not lapsed, and those shares of Company Stock must be immediately returned to the Company. The Committee may, however, provide for complete or partial exceptions to this requirement as it deems appropriate.

A-5


(d)Restrictions on Transfer and Legend Stock Certificate. During the Restriction Period, a Grantee may not sell, assign, transfer, pledge or otherwise dispose of the shares of a Stock Award except to a Successor Grantee under Section 11(a). Each certificate for a share of a Stock Award shall contain a legend giving appropriate notice of the restrictions in the Grant. The Grantee shall be entitled to have the legend removed from the stock certificate covering the shares subject to restrictions when all restrictions on such shares have lapsed. The Committee may determine that the Company will not issue certificates for Stock Awards until all restrictions on such shares have lapsed, or that the Company will retain possession of certificates for shares of Stock Awards until all restrictions on such shares have lapsed.
(e)Right to Vote and to Receive Dividends. Unless the Committee determines otherwise, during the Restriction Period, the Grantee shall have the right to vote shares of Stock Awards and to receive any dividends or other distributions paid on such shares, subject to any restrictions deemed appropriate by the Committee, including, without limitation, the achievement of specific performance goals. In the event the Grantee has the right to receive dividends or other distributions paid on shares of any Stock Award, the Grant Instrument shall be prepared to comply with the applicable requirements of section 409A of the Code and shall be interpreted in a manner consistent with such requirements.
(f)Lapse of Restrictions. All restrictions imposed on Stock Awards shall lapse upon the expiration of the applicable Restriction Period and the satisfaction of all conditions imposed by the Committee. The Committee may determine, as to any or all Stock Awards, that the restrictions shall lapse without regard to any Restriction Period.
(g)Code Section 409A. The terms and conditions set forth in Grant Instruments for Stock Awards shall be prepared to comply with the applicable requirements of section 409A of the Code and interpreted in a manner consistent with such requirements to the extent the Committee believes the Stock Award is subject to such requirements.
7.Performance Units.
(a)General Requirements. The Committee may grant performance units (“Performance Units”) to an Employee or Key Advisor. Each Performance Unit shall represent the right of the Grantee to receive an amount based on the value of the Performance Unit, if performance goals established by the Committee are met. The value of a Performance Unit shall equal the Fair Market Value of a share of Company Stock. The Committee shall determine the number of Performance Units to be granted and the requirements applicable to such Units.
(b)Performance Period and Performance Goals. When Performance Units are granted, the Committee shall establish the performance period during which performance shall be measured (the “Performance Period”), performance goals applicable to the Units (“Performance Goals”) and such other conditions of the Grant as the Committee deems appropriate. Performance Goals may relate to the financial performance of the Company or its operating units, the performance of Company Stock, individual performance, or such other criteria as the Committee deems appropriate. Performance Units shall be subject to the following criteria:
(i)Minimum Duration of Performance Period. The Committee shall not establish a Performance Period which has a duration of less than twelve (12) consecutive months.
(ii)Pre-established Performance Goals. The Committee shall establish the Performance Goals in writing no later than ninety (90) days after the commencement of the Performance Period, provided that the outcome is substantially uncertain at the time the Performance Goals are established.
(iii)Initial Deferral Election. An Employee or Key Advisor receiving a Grant of Performance Units must make a deferral election no later than the date which is six (6) months before the end of the Performance Period, provided that in no event may a deferral election be made after such Performance Goals have become both substantially certain to be paid and readily ascertainable.

A-6


(iv)Code Section 409A. The terms and conditions set forth in a Grant of Performance Units shall comply with the applicable requirements of section 409A of the Code and interpreted in a manner consistent with such requirements to the extent the Committee believes a Grant of Performance Units is subject to such requirements.
(c)Payment with respect to Performance Units. At the end of each Performance Period, the Committee shall determine to what extent the Performance Goals and other conditions of the Performance Units are met, the value of the Performance Units (if applicable), and the amount, if any, to be paid with respect to the Performance Units. Payments with respect to Performance Units shall be made in cash, in Company Stock or in a combination of the two, as determined by the Committee.
(d)Requirement of Employment or Service. If the Grantee ceases to be employed by, or provide service to, the Company (as defined in Section 5(e)) during a Performance Period, or if other conditions established by the Committee are not met, the Grantee’s Performance Units shall be forfeited. The Committee may, however, provide for complete or partial exceptions to this requirement as it deems appropriate.
8.Qualified Performance-Based Compensation.
(a)Designation as Qualified Performance-Based Compensation. The Committee may determine that Performance Units or Stock Awards granted to an Employee shall be considered “qualified performance-based compensation” under Section 162(m) of the Code. The provisions of this Section 8 shall apply to Grants of Performance Units and Stock Awards that are to be considered “qualified performance-based compensation” under section 162(m) of the Code.
(b)Performance Goals. When Performance Units or Stock Awards that are to be considered “qualified performance-based compensation” are granted, the Committee shall establish in writing (i) the objective performance goals that must be met in order for restrictions on the Stock Awards to lapse or amounts to be paid under the Performance Units, (ii) the Performance Period during which the performance goals must be met, (iii) the threshold, target and maximum amounts that may be paid if the performance goals are met, and (iv) any other conditions that the Committee deems appropriate and consistent with the Plan and section 162(m) of the Code. The performance goals may relate to the Employee’s business unit or the performance of the Company and its subsidiaries as a whole, or any combination of the foregoing. The Committee shall use objectively determinable performance goals based on one or more of the following criteria: stock price, earnings per share, net earnings, operating earnings, return on assets, shareholder return, return on equity, growth in assets, achievement of regulatory approvals or patents, sales, market share or strategic business criteria consisting of one or more objectives based on meeting specified revenue goals, market penetration goals, geographic business expansion goals, cost targets, scientific milestones, commercial milestones, goals relating to acquisitions or divestitures, joint ventures or strategic partnerships.
(c)Establishment of Goals. The Committee shall establish the performance goals in writing either before the beginning of the Performance Period or during a period ending no later than the earlier of (i) ninety (90) days after the commencement of the Performance Period or (ii) the date on which twenty-five percent (25%) of the Performance Period has been completed, or such other date as may be required or permitted under applicable regulations under sections 162(m) and 409A of the Code. The performance goals shall satisfy the requirements for “qualified performance-based compensation,” including the requirement that the achievement of the goals be substantially uncertain at the time they are established and that the goals be established in such a way that a third party with knowledge of the relevant facts could determine whether and to what extent the performance goals have been met. The Committee shall not have discretion to increase the amount of compensation that is payable upon achievement of the designated performance goals.
(d)Initial Deferral Election. A Grantee receiving a Grant of qualified performance-based compensation must make any deferral election allowed under Section 9 no later than the date which is six (6) months before the end of the Performance Period, provided that in no event may a deferral election be made after such Performance Goals have become both substantially certain to be paid and readily ascertainable.

A-7


(e)Code Section 409A. The terms and conditions set forth in a Grant of qualified performance-based compensation shall comply with the applicable requirements of section 409A of the Code and interpreted in a manner consistent with such requirements to the extent the Committee believes a Grant of qualified performance-based compensation is subject to such requirements.
(f)Maximum Payment. Performance Units and Stock Awards under this Section 8 may be granted to an Employee with respect to not more than 250,000 shares of Company Stock for any Performance Period.
(g)Announcement of Grants. The Committee shall certify and announce the results for each Performance Period to all Grantees immediately following the announcement of the Company’s financial results for the Performance Period. If and to the extent that the Committee does not certify that the performance goals have been met, the grants of Stock Awards or Performance Units for the Performance Period shall be forfeited.
(h)Death, Disability, Change of Control or Other Circumstances. The Committee may provide in the award that Performance Units shall be payable or restrictions on Stock Awards shall lapse, in whole or in part, in the event of the Grantee’s death or Disability (as defined in Section 5(e) above) during the Performance Period, or under other circumstances consistent with the regulations and rulings under sections 162(m) and 409A of the Code, and the provisions of Section 13 shall apply in the event of a Change of Control.
9.Deferrals.
The Committee may permit or require a Grantee to defer receipt of the payment of cash or the delivery of shares that would otherwise be due to such Grantee in connection with any Option, the lapse or waiver of restrictions applicable to Stock Awards, or the satisfaction of any requirements or objectives with respect to Performance Units. Awards shall comply with the applicable requirements of section 409A of the Code and be interpreted in a consistent manner whenever (a) the Grantee is permitted to defer receipt of the payment of cash or the delivery of stock, or (b) the Committee’s lapse or waiver of restrictions brings the compensatory arrangement within the requirements of section 409A of the Code.
10.Withholding of Taxes.
(a)Required Withholding. All Grants under the Plan shall be subject to applicable federal (including FICA), state and local tax withholding requirements. The Company shall have the right to deduct from all Grants paid in cash, or from other wages paid to the Grantee, any federal, state or local taxes required by law to be withheld with respect to such Grants. In the case of Options, Stock Awards and other Grants paid in Company Stock, the Company may require that the Grantee or other person receiving or exercising Grants pay to the Company the amount of any federal, state or local taxes that the Company is required to withhold with respect to such Grants, or the Company may deduct from other wages paid by the Company the amount of any withholding taxes due with respect to such Grants.
(b)Election to Withhold Shares. If the Committee so permits, a Grantee may elect to satisfy the Company’s income tax withholding obligation with respect to Options, Stock Awards or Performance Units paid in Company Stock by having shares withheld up to an amount that does not exceed the Grantee’s minimum applicable withholding tax rate for federal (including FICA), state and local tax liabilities. The election must be in a form and manner prescribed by the Committee and may be subject to the prior approval of the Committee.
11.Transfer of Grants.
(a)Nontransferability of Grants. Except as provided below, only the Grantee may exercise rights under a Grant during the Grantee’s lifetime. A Grantee may not transfer those rights except by will or by the laws of descent and distribution or, with respect to Grants other than Incentive Stock Options, if permitted in any specific case by the Committee, pursuant to a domestic relations order. When a Grantee dies, the personal representative or other person entitled to succeed to the rights of the Grantee (“Successor Grantee”) may exercise such rights. A Successor Grantee must furnish proof satisfactory to the Company of his or her right to receive the Grant under the Grantee’s will or under the applicable laws of descent and distribution.

A-8


(b)Transfer of Nonqualified Stock Options. Notwithstanding the foregoing, the Committee may provide, in a Grant Instrument, that a Grantee may transfer Nonqualified Stock Options to immediate family members, or one or more trusts or other entities for the benefit of or owned by immediate family members, consistent with the applicable securities laws, according to such terms as the Committee may determine; provided that the Grantee receives no consideration for the transfer of an Option and the transferred Option shall continue to be subject to the same terms and conditions as were applicable to the Option immediately before the transfer.
12.Change of Control of the Company.
As used herein, a “Change of Control” shall be deemed to have occurred if:
(a)Any “person” (defined to have the meaning in this definition of Change of Control as is assigned that term in sections 13(d) and 14(d) of the Exchange Act) other than an “Excluded Shareholder” (as defined herein) becomes a “beneficial owner” (as defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of securities of the Company representing more than fifty percent (50%) of the voting power of the then outstanding securities of the Company; provided that a Change of Control shall not be deemed to occur as a result of a transaction in which the Company becomes a subsidiary of another corporation and in which the shareholders of the Company, immediately prior to the transaction, will beneficially own, immediately after the transaction, shares entitling such shareholders to more than fifty percent (50%) of all votes to which all shareholders of the parent corporation would be entitled in the election of directors (without consideration of the rights of any class of stock to elect directors by a separate class vote); the term “Excluded Shareholder” meaning, for purposes of this definition of Change of Control, any person who is the beneficial owner, directly or indirectly of more than twenty percent (20%) of the voting power of the then outstanding securities of the Company; or
(b)The shareholders of the Company approve (or, if shareholder approval is not required, the Board approves) an agreement providing for (i) the merger or consolidation of the Company with another corporation where the shareholders of the Company, immediately prior to the merger or consolidation, will not beneficially own, immediately after the merger or consolidation, shares entitling such shareholders to more than fifty percent (50%) of all votes to which all shareholders of the surviving corporation would be entitled in the election of directors (without consideration of the rights of any class of stock to elect directors by a separate class vote) or (ii) the sale or other disposition of assets equal to or greater than forty percent (40%) of the total gross fair market value of all assets of the Company immediately prior to such sale or disposition.
13.Consequences of a Change Control.
(a)Assumption of Grants. Upon a Change of Control where the Company is not the surviving corporation (or survives only as a subsidiary of another corporation), unless the Committee determines otherwise, all outstanding Options that are not exercised shall be assumed by, or replaced with comparable options or rights by the surviving corporation (or a parent of the surviving corporation), and other outstanding Grants shall he converted to similar grants of the surviving corporation (or a parent of the surviving corporation).
(b)Other Alternatives. Notwithstanding the foregoing, the Committee may provide in the Grant Instrument that one or more of the following actions shall occur in the event of a Change of Control: (i) outstanding Options shall automatically accelerate and become fully exercisable and that the restrictions and conditions on outstanding Stock Awards shall immediately lapse, (ii) Grantees holding Performance Units shall receive a payment in settlement of such Performance Units in an amount determined by the Committee, (iii) Grantees shall surrender their outstanding Options in exchange for a payment by the Company, in cash or Company Stock as determined by the Committee, in an amount equal to the amount by which the then Fair Market Value of the shares of Company Stock subject to the Grantee’s unexercised Options exceeds the Exercise Price of the Options, or (iv) giving Grantees an opportunity to exercise their outstanding Options, terminate any or all unexercised Options at such time as the Committee deems appropriate. Such surrender, termination or settlement shall take place as of the date of the Change of Control or such other date as the Committee may specify. The Committee shall have no obligation to take any of the foregoing actions, and, in the absence of any such actions, outstanding Grants shall continue in effect according to their terms (subject to any assumption pursuant to Subsection (a)).

A-9


14.Requirements for Issuance or Transfer of Shares.
(a)Limitations on Issuance or Transfer of Shares. No Company Stock shall be issued or transferred in connection with any Grant hereunder unless and until all legal requirements applicable to the issuance or transfer of such Company Stock have been complied with to the satisfaction of the Committee. The Committee shall have the right to condition any Grant made to any Grantee hereunder on such Grantee’s undertaking in writing to comply with such restrictions on his or her subsequent disposition of such shares of Company Stock as the Committee shall deem necessary or advisable, and certificates representing such shares may be legended to reflect any such restrictions. Certificates representing shares of Company Stock issued or transferred under the Plan will be subject to such stop-transfer orders and other restrictions as may be required by applicable laws, regulations and interpretations, including any requirement that a legend be placed thereon.
(b)Lock-Up Period. If so requested by the Company or any representative of the underwriters (the “Managing Underwriter”) in connection with any underwritten offering of securities of the Company under the Securities Act of 1933, as amended (the “Securities Act”) a Grantee (including any successors or assigns) shall not sell or otherwise transfer any shares or other securities of the Company during the 30-day period preceding and the 180-day period following the effective date of a registration statement of the Company filed under the Securities Act for such underwriting (or such shorter period as may be requested by the Managing Underwriter and agreed to by the Company) (the “Market Standoff Period”). The Company may impose stop-transfer instructions with respect to securities subject to the foregoing restrictions until the end of such Market Standoff Period. Certificates representing Company stock issued upon exercise of Options or otherwise pursuant to the Plan shall bear such legend regarding the lock-up period obligations as counsel to the Company shall determine.
(c)Sales to Competitors. Prior to the initial public offering of shares of Company common stock, no Company stock issued in connection with any Grant hereunder may be sold, assigned or otherwise transferred to any competitor of the Company or any entity which owns in excess of one percent (1%) of the voting stock of any such competitor, provided Grantee has actual knowledge of such ownership. Certificates representing shares of Company stock so issued in connection with a Grant hereunder shall bear such legend regarding sales to competitors and other obligations as counsel to the Company shall determine.
15.Amendment and Termination of the Plan.
(a)Amendment. The Board may amend or terminate the Plan at any time; provided, however, that the Board shall not amend the Plan without shareholder approval if (i) such approval is required in order for Incentive Stock Options granted or to be granted under the Plan to meet the requirements of section 422 of the Code, (ii) such approval is required in order to exempt compensation under the Plan from the deduction limit under section 162(m) of the Code, or (iii) such approval is required by applicable stock exchange requirements. When amending or terminating the Plan, the Board shall act in a manner consistent with section 409A of the Code and no Board action shall cause the application of the twenty percent (20%) penalty or immediate tax recognition under section 409A of the Code.
(b)Shareholder Approval for “Qualified Performance-Based Compensation”. If Performance Units or Stock Awards are granted as “qualified performance-based compensation” under Section 8 above, the Plan must be reapproved by the shareholders no later than the first shareholders meeting that occurs in the fifth year following the year in which the shareholders previously approved the provisions of Section 8, if required by section 162(m) of the Code or the regulations thereunder.
(c)Termination of Plan. The Plan shall terminate on the day immediately preceding the tenth anniversary of its effective date, unless the Plan is terminated earlier by the Board or is extended by the Board with the approval of the shareholders.
(d)Termination and Amendment of Outstanding Grants. A termination or amendment of the Plan that occurs after a Grant is made shall not materially impair the rights of a Grantee unless the Grantee consents or unless the Committee acts under Section 21(b). The termination of the Plan shall not impair the power and authority of the Committee with respect to an outstanding Grant. Whether or not the Plan has terminated, an outstanding Grant may be terminated or amended under Section 21(b) or may be amended by agreement of the Company and the Grantee consistent with the Plan.

A-10

(e)Governing Document. The Plan shall be the controlling document. No other statements, representations, explanatory materials or examples, oral or written, may amend the Plan in any manner. The Plan shall be binding upon and enforceable against the Company and its successors and assigns.
16.Funding the Plan.
This Plan shall be unfunded. The Company shall not be required to establish any special or separate fund or to make any other segregation of assets to assure the payment of any Grants under this Plan. In no event shall interest be paid or accrued on any Grant, including unpaid installments of Grants.
17.Rights of Participants.
Nothing in this Plan shall entitle any Employee, Key Advisor, Non-Employee Director or other person to any claim or right to be granted a Grant under this Plan. Neither this Plan nor any action taken hereunder shall be construed as giving any individual any rights to be retained by or in the employ of the Company or any other employment rights.
18.No Fractional Shares.
No fractional shares of Company Stock shall be issued or delivered pursuant to the Plan or any Grant. The Committee shall determine whether cash, other awards or other property shall be issued or paid in lieu of such fractional shares or whether such fractional shares or any rights thereto shall be forfeited or otherwise eliminated.
19.Heading.
Section headings are for reference only. In the event of a conflict between a title and the content of a Section, the content of the Section shall control.
20.Effective Date of the Plan.
The Plan was effective May 22, 2001, and the amendment and restatement shall be effective January 1, 2005.
21.Miscellaneous.
(a)Grants in Connection with Corporate Transactions and Otherwise. Nothing contained in this Plan shall be construed to (i) limit the right of the Committee to make Grants under this Plan in connection with the acquisition, by purchase, lease, merger, consolidation or otherwise, of the business or assets of any corporation, firm or association, including Grants to employees thereof who become Employees of the Company, or for other proper corporate purposes, or (ii) limit the right of the Company to grant stock options or make other awards outside of this Plan. Without limiting the foregoing, the Committee may make a Grant to an employee of another corporation who becomes an Employee by reason of a corporate merger, consolidation, acquisition of stock or property, reorganization or liquidation involving the Company or any of its subsidiaries in substitution for a stock option or stock award grant made by such corporation. The terms and conditions of the substitute grants may vary from the terms and conditions required by the Plan and from those of the substituted stock incentives. The Committee shall prescribe the provisions of the substitute grants.
(b)Compliance with Law. The Plan, the exercise of Options and the obligations of the Company to issue or transfer shares of Company Stock under Grants shall be subject to all applicable laws and to approvals by any governmental or regulatory agency as may be required. With respect to persons subject to section 16 of the Exchange Act, it is the intent of the Company that the Plan and all transactions under the Plan comply with all applicable provisions of Rule 16b-3 or its successors under the Exchange Act. In addition, it is the intent of the Company that the Plan and applicable Grants under the Plan comply with the applicable provisions of section 162(m), section 409A and section 422 of the Code. To the extent that any legal requirement of section 16 of the Exchange Act or section 162(m), section 409A or section 422 of the Code as set forth in the Plan ceases to be required under section 16 of the
A-11


Exchange Act or section 162(m), section 409A or section 422 of the Code, that Plan provision shall cease to apply. The Committee may revoke any Grant if it is contrary to law or modify a Grant to bring it into compliance with any valid and mandatory government regulation. The Committee may also adopt rules regarding the withholding of taxes on payments to Grantees. The Committee may, in its sole discretion, agree to limit its authority under this Section.
(c)Savings Provision. In the event any provision of this Plan shall be deemed to cause the application of the twenty percent (20%) penalty or immediate tax recognition under section 409A of the Code, the provision that causes either the application of the penalty or immediate tax recognition shall become null and void, and the Plan shall be construed and enforced as if the provision causing the negative tax consequences had never been contained herein.
(d)Governing Law. The validity, construction, interpretation and effect of the Plan and Grant Instruments issued under the Plan shall be governed and construed by and determined in accordance with the laws of Florida, without giving effect to the conflict of laws provisions thereof.

ANNEX B
DYADIC INTERNATIONAL, INC.
2006 STOCK OPTION PLAN
The purpose of the Dyadic International, Inc. 2006 Stock Option Plan (the “Plan”) is to provide (i) designated Employees of DYADIC INTERNATIONAL, INC. (the “Company”) and its subsidiaries, (ii) Key Advisors who perform consulting or advisory services for the Company or its Subsidiaries and (iii) Non-Employee Directors who serve on the Board of Directors of the Company (the “Board”) with the opportunity to receive grants of incentive stock options and nonqualified stock options. The Company believes that the Plan will encourage the participants to contribute materially to the growth of the Company, thereby benefiting the Company’s stockholders, and will align the economic interests of the participants with those of the stockholders. A Glossary of defined terms used in this Plan is set forth in Section 18 hereof.
1.Administration.
(a)Committee. The Plan shall be administered by the Compensation Committee of the Board, a majority of whose members are “outside directors” as defined under section 162(m) of the Code and related Treasury regulations, and “non-employee directors” as defined under Rule 16b-3 under the Exchange Act (the “Committee”). However, the Board may ratify or approve any grants as it deems appropriate.
(b)Committee Authority. The Committee shall have the sole authority to (i) determine the individuals to whom grants shall be made under the Plan, (ii) determine the type, size and terms of the Grants to be made to each such individual, (iii) determine the time when the Grants will be made and the duration of any applicable exercise or restriction period, including the criteria for exercisability and the acceleration of exercisability, (iv) amend the terms of any previously issued grant, and (v) deal with any other matters arising under the Plan. In the event the Committee determines section 409A of the Code may be applicable to an Option granted hereunder, the Plan shall prohibit the acceleration of the time or schedule of payment of compensation hereunder, except to the extent permitted under section 409A of the Code and the applicable Treasury regulations thereunder.
(c)Committee Determinations. The Committee shall have full power and authority to administer and interpret the Plan, to make factual determinations and to adopt or amend such rules, regulations, agreements and instruments for implementing the Plan and for the conduct of its business as it deems necessary or advisable, in its sole discretion. The Committee’s interpretations of the Plan and all determinations made by the Committee pursuant to the powers vested in it hereunder shall be conclusive and binding on all persons having any interest in the Plan or in any awards granted hereunder. All powers of the Committee shall be executed in its sole discretion, in the best interest of the Company, not as a fiduciary, and in keeping with the objectives of the Plan and need not be uniform as to similarly situated individuals.
2.Grants.
Grants of Options under the Plan may consist of Incentive Stock Options as described in Section 5 or Nonqualified Stock Options as described in Section 5. All Grants shall be subject to the terms and conditions set forth herein and to such other terms and conditions consistent with this Plan as the Committee deems appropriate and as are specified in a Grant Instrument or amendment thereto. The Committee shall approve the form and provisions of each Grant Instrument. Grants under a particular Section of the Plan need not be uniform as among the grantees.
3.Shares Subject to the Plan.
(a)Shares Authorized. Subject to adjustment as described below, the aggregate number of shares of Company Stock that may be issued or transferred under the Plan is 2,700,000 shares. The maximum aggregate number of shares of Company Stock that shall be subject to Grants made under the Plan to any individual during any calendar year shall be 1,200,000 shares, subject to adjustment as described below. The shares may be authorized but
B-1


unissued shares of Company Stock or reacquired shares of Company Stock, including shares purchased by the Company on the open market for purposes of the Plan. If and to the extent Options granted under the Plan terminate, expire, or are canceled, forfeited, exchanged or surrendered without having been exercised, the shares subject to such Grants shall again be available for purposes of the Plan.
(b)Adjustments. If there is any change in the number or kind of shares of Company Stock outstanding (i) by reason of a stock dividend, spinoff, recapitalization, stock split, or combination or exchange of shares, (ii) by reason of a merger, reorganization or consolidation in which the Company is the surviving corporation, (iii) by reason of a reclassification or change in par value, or (iv) by reason of any other extraordinary or unusual event affecting the outstanding Company Stock as a class without the Company’s receipt of consideration, or if the value of outstanding shares of Company Stock is substantially reduced as a result of a spinoff or the Company’s payment of an extraordinary dividend or distribution, the maximum number of shares of Company Stock available for Grants, then in that event (A) the maximum number of shares of Company Stock that any individual participating in the Plan may be panted in any year, (B) the number of shares covered by outstanding Grants, (C) the kind of shares issued under the Plan, and (D) the price per share or the applicable market value of such Grants may be appropriately adjusted by the Committee to reflect any increase or decrease in the number of, or change in the kind or value of, issued shares of Company Stock to preclude, to the extent practicable, the enlargement or dilution of rights and benefits under such Grants; provided, however, that any fractional shares resulting from such adjustment shall be eliminated. Any adjustments determined by the Committee shall be final, binding and conclusive.
4.Eligibility for Participation.
(a)Eligible Persons. All Employees of the Company and its Subsidiaries, including Employees who are officers or members of the Board, and Non-Employee Directors shall be eligible to participate in the Plan. Key Advisors who perform services for the Company or any of its Subsidiaries shall be eligible to participate in the Plan if (i) they render bona fide services to the Company or its Subsidiaries, (ii) the services are not in connection with the offer and sale of securities in a capital-raising transaction and (iii) such Key Advisors do not directly or indirectly promote or maintain a market for the Company’s securities.
(b)Selection of Grantees. The Committee shall select the Employees, Non-Employee Directors and Key Advisors to receive Grants and shall determine the number of shares of Company Stock subject to a particular Grant in such manner as the Committee determines. Employees, Key Advisors and Non-Employee Directors who receive Grants under this Plan shall hereinafter be referred to as “Grantees.”
5.Granting of Options.
(a)Number of Shares. The Committee shall determine the number of shares of Company Stock that will be subject to each Grant of Options to Employees, Non-Employee Directors and Key Advisors.
(b)Type of Option and Price.
(i)The Committee may grant Incentive Stock Options that are intended to qualify as “Incentive Stock Options” within the meaning of section 422 of the Code or Nonqualified Stock Options that are not intended so to qualify or any combination of Incentive Stock Options and Nonqualified Stock Options, all in accordance with the terms and conditions set forth in this Plan. Incentive Stock Options may be granted only to Employees. Nonqualified Stock Options may be granted to Employees, Non-Employee Directors and Key Advisors.
(ii)The purchase price (the “Exercise Price”) of Company Stock subject to an Option shall be determined by the Committee and shall be equal to or greater than the Fair Market Value (as defined below) of a share of Company Stock on the date the Option is granted; provided, however, that an Incentive Stock Option shall not be granted to an Employee who, at the time of grant, owns stock possessing more than ten percent (10%) of the total combined voting power of all classes of stock of the Company or any parent or subsidiary of the Company, unless the Exercise Price per share is not less than one hundred ten percent (110%) of the Fair Market Value of Company Stock on the date of grant.

B-2


(iii)While the Company Stock is publicly traded, the Fair Market Value per share shall be determined as follows: (x) if the principal trading market for the Company Stock is a national securities exchange or the Nasdaq National Market, the last reported sale price thereof on the relevant date or (if there were no trades on that date) the latest preceding date upon which a sale was reported. or (y) if the Company Stock is not principally traded on such exchange or market, the mean between the last reported “bid” and “asked” prices of Company Stock on the relevant date, as reported on Nasdaq or, if not so reported, as reported by the National Daily Quotation Bureau, Inc. or as reported in a customary financial reporting service, as applicable and as the Committee determines. If the Company Stock ever ceases to be publicly traded or, if publicly traded, is not subject to reported transactions or “bid” or “asked” quotations as set forth above, the Fair Market Value per share shall be as determined by the Committee.
(c)Option Term. The Committee shall determine the term of each Option. The term of any Option shall not exceed ten (10) years from the date of grant. However, an Incentive Stock Option that is granted to an Employee who, at the time of owns stock possessing more than ten percent (10%) of the total combined voting power of all classes of stock of the Company, or any parent or subsidiary of the Company, may not have a term that exceeds five years from the date of grant.
(d)Exercisability of Options. Options shall become exercisable in accordance with such terms and conditions, consistent with the Plan, as may be determined by the Committee and specified in the Grant Instrument. The Committee may waive or accelerate the satisfaction of an exercise term or condition of any or all outstanding Options at any time for any reason.
(e)Termination of Employment, Disability or Death.
(i)Except as provided below, an Option may only be exercised while the Grantee is employed by, or providing service to, the Company as an Employee, Key Advisor or member of the Board. In the event that a Grantee ceases to be employed by the Company (in the case of an Employee), serve on the Board (in the case of a Non-Employee Director) or provide service to, the Company (in the case of a Key Advisor) for any reason other than Disability, death, or termination for Cause, any Option which is otherwise exercisable by the Grantee shall terminate unless exercised within 90 days after the date on which the Grantee ceases to be employed by, serve on the Board of, or provide service to, the Company, as applicable, or within such other period of time as may be specified by the Committee, but in any event no later than the date of expiration of the Option term. Except as otherwise provided by the Committee any of the Grantee’s Options that are not otherwise exercisable as of the date on which the Grantee ceases to be employed by, or provide service to, the Company shall terminate as of such date.
(ii)In the event the Grantee ceases to be employed by the Company (in the case of Employees), serve on the Board (in the case of a Non-Employee Director) or provide service to the Company (in the case of a Key Advisor) on account of a termination for Cause by the Company, any Option held by that Grantee shall terminate as of the date such Grantee ceases to be employed by, serve on the Board or provide service to, the Company, as applicable. In addition, notwithstanding any other provisions of this Section 5, if the Committee determines that the Grantee has engaged in conduct that constitutes Cause at any time while the Grantee is employed by, serving on the Board or providing service to, as applicable, the Company or after the Grantee’s termination of employment, Board membership or service, as applicable, any Option held by that Grantee shall immediately terminate and that Grantee shall automatically forfeit all shares underlying any exercised portion of an Option for which the Company has not yet delivered the share certificates, upon refund by the Company of the Exercise Price paid by that Grantee for such shares. Upon any exercise of an Option, the Company may withhold delivery of share certificates pending resolution of an inquiry that could lead to a finding resulting in a forfeiture.
(iii)In the event the Grantee ceases to be employed by, serve on the Board or provide service to, the Company, as applicable, because the Grantee is Disabled, any Option which is otherwise exercisable by that Grantee shall terminate unless exercised within one year after the date on which that Grantee ceases to be employed by, be on the Board or provide service to, the Company, as applicable (or within such other period of time as may be specified by the Committee), but in any event no later than the date of expiration of the Option term. Except as otherwise provided by the Committee, any of a Grantee’s Options which are not otherwise exercisable as of the date on which the Grantee ceases to be employed by, serve on the Board or provide service to, the Company, as applicable, shall terminate as of such date.

B-3


(iv)If the Grantee dies while employed by, serving on the Board or providing service to, the Company, as applicable, or within 90 days after the date on which the Grantee ceases to be employed, serve on the Board or provide service on account of a termination specified in Section 5(e)(i) above (or within such other period of time as may be specified by the Committee), any Option that is otherwise exercisable by that Grantee shall terminate unless exercised within one year after the date on which that Grantee ceases to be employed by, serve on the Board or provide service to, the Company, as applicable (or within such other period of time as may be specified by the Committee), but in any event no later than the date of expiration of the Option term. Except as otherwise provided by the Committee, any of the Grantee’s Options that are not otherwise exercisable as of the date on which the Grantee ceases to be employed by, or provide service to, the Company shall terminate as of such date.
(f)Exercise of Options. A Grantee may exercise an Option that has become exercisable, in whole or in part, by delivering a notice of exercise to the Company with payment of the Exercise Price. The Grantee shall pay the Exercise Price for an Option as specified by the Committee (w) in cash, (x) with the approval of the Committee, by delivering shares of Company Stock owned by the Grantee (including Company Stock acquired in connection with the exercise of an Option, subject to such restrictions as the Committee deems appropriate) and having a Fair Market Value on the date of exercise equal to the Exercise Price or by attestation (on a form prescribed by the Committee) to ownership of shares of Company Stock having a Fair Market Value on the date of exercise equal to the Exercise Price, (y) pay through a broker in accordance with procedures permitted by Regulation T of the Federal Reserve Board, or (z) by such other method as the Committee may approve. The Committee may authorize loans by the Company to Grantees in connection with the exercise of an Option, upon such terms and conditions as the Committee, in its sole discretion, deems appropriate. Shares of Company Stock used to exercise an Option shall have been held by the Grantee for the requisite period of time to avoid adverse accounting consequences to the Company with respect to the Option. The Grantee shall pay the Exercise Price and the amount of any withholding tax due at the time of exercise.
(g)Limits on Incentive Stock Options. Each Incentive Stock Option shall provide that, if the aggregate Fair Market Value of the stock on the date of the grant with respect to which Incentive Stock Options are exercisable for the first time by a Grantee during any calendar year, under the Plan or any other stock option plan of the Company or a parent or subsidiary, exceeds $100,000, then the Option, as to the excess, shall be treated as a Nonqualified Stock Option. An Incentive Stock Option shall not be granted to any person who is not an Employee of the Company or a parent or subsidiary (within the meaning of section 424(f) of the Code).
6.Withholding of Taxes.
(a)Required Withholding. All Grants under the Plan shall be subject to any applicable federal (including FICA), state and local tax withholding requirements. The Company shall have the right to deduct from other wages paid to the Grantee, any federal, state or local taxes required by law to be withheld with respect to such Grants or any exercise thereof. In the case of Options paid in Company Stock, the Company may require that the Grantee or other person receiving or exercising Grants pay to the Company the amount of any federal, state or local taxes that the Company is required to withhold with respect to such Grants, or the Company may deduct from other wages paid by the Company the amount of any withholding taxes due with respect to such Grants.
(b)Election to Withhold Shares. If the Committee so permits, a Grantee may elect to satisfy the Company’s income tax withholding obligation with respect to Options paid in Company Stock by having shares withheld up to an amount that does not exceed the Grantee’s minimum applicable withholding tax rate for federal (including FICA), state and local tax liabilities. The election must be in a form and manner prescribed by the Committee and may be subject to the prior approval of the Committee.
7.Transfer of Grants.
(a)Nontransferability of Grants. Except as provided below, only the Grantee may exercise rights under a Grant during the Grantee’s lifetime. A Grantee may not transfer those rights except by will or by the laws of descent and distribution or, with respect to Grants other than Incentive Stock Options, if permitted in any specific case by the Committee, pursuant to a domestic relations order. When a Grantee dies, such Grantee’s Successor Grantee may exercise such rights, provided that any such Successor Grantee must furnish proof satisfactory to the Company of his or her right to receive the Grant under the Grantee’s will or under the applicable laws of descent and distribution.

B-4

(b)Transfer of Nonqualified Stock Options. Notwithstanding the foregoing, the Committee may provide, in a Grant Instrument, that a Grantee may transfer Nonqualified Stock Options to immediate family members, or one or more trusts or other entities for the benefit of or owned by immediate family members, consistent with the applicable securities laws, according to such terms as the Committee may determine; provided that the Grantee receives no consideration for the transfer of an Option and the transferred Option shall continue to be subject to the same terms and conditions as were applicable to the Option immediately before the transfer.
8.Consequences of a Change of Control.
(a)Assumption of Grants. Upon the occurrence of a Change of Control in which the Company is not the surviving corporation (or survives only as a subsidiary of another corporation), unless the Committee determines otherwise, all outstanding Options that are not exercised shall be assumed by, or replaced with comparable options or rights by the surviving corporation (or a parent of the surviving corporation), and other outstanding Grants shall he converted to similar grants of the surviving corporation (or a parent of the surviving corporation).
(b)Other Alternatives. Notwithstanding the foregoing, in the event of a Change in Control, the Committee may, but shall not be obligated to, take any of the following actions with respect to any or all outstanding Grants: the Committee may (i) determine that outstanding Options shall automatically accelerate and become fully exercisable, (ii) require that Grantees surrender their outstanding Options in exchange for a payment by the Company, in cash or Company Stock as determined by the Committee, in an amount equal to the amount by which the then Fair Market Value of the shares of Company Stock subject to the Grantee’s unexercised Options exceeds the Exercise Price of the Options or (iii) after giving Grantees an opportunity exercise their outstanding Options, terminate any or all unexercised Options at such time as the Committee deems appropriate. Such surrender, termination or settlement shall take place as of the date of the Change of Control or such other date as the Committee may specify. The Committee shall have no obligation to take any of the foregoing actions, and, in the absence of any such actions, outstanding Grants shall continue in effect according to their terms (subject to any assumption pursuant to Subsection (a)).
9.Requirements for Issuance or Transfer of Shares.
(a)Limitations on Issuance or Transfer of Shares. No Company Stock shall be issued or transferred in connection with any Grant hereunder unless and until all legal requirements applicable to the issuance or transfer of such Company Stock have been complied with to the satisfaction of the Committee. The Committee shall have the right to condition any Grant made to any Grantee hereunder on such Grantee’s undertaking in writing to comply with such restrictions on his or her subsequent disposition of such shares of Company Stock as the Committee shall deem necessary or advisable, and certificates representing such shares maybe legended to reflect any such restrictions. Certificates representing shares of Company Stock issued or transferred under the Plan will be subject to such stop-transfer orders and other restrictions as may be required by applicable laws, regulations and interpretations, including any requirement that a legend be placed thereon.
(b)Lock-Up Period. If so requested by the Company or any representative of the underwriters (the “Managing Underwriter”) in connection with any underwritten offering of securities of that Company under the Securities Act a Grantee (including any successors or assigns) shall not sell or otherwise transfer any shares or other securities of the Company during the 30-day period preceding and the 180-day period following the effective date of a registration statement of the Company filed under the Securities Act for such underwriting (or such shorter period as may be requested by the Managing Underwriter and agreed to by the Company) (the “Market Standoff Period”). The Company may impose stop-transfer instructions with respect to securities subject to the foregoing restrictions until the end of such Market Standoff Period. Certificates representing Company stock issued upon exercise of Options or otherwise pursuant to the Plan shall bear such legend regarding the lock-up period obligations as counsel to the Company shall determine.

(c)Termination and Amendment of Outstanding Grants. A termination or amendment of the Plan that occurs after a Grant is made shall not materially impair the rights of a Grantee unless the Grantee consents or unless the Committee acts under Section 16(b) hereunder. The termination of the Plan shall not impair the power and authority of the Committee with respect to an outstanding Grant. Whether or not the Plan has terminated, an outstanding Grant may be terminated or amended under Section 16(b) hereunder or may be amended by agreement of the Company and the Grantee consistent with the Plan.
(d)Governing Document. The Plan shall be the controlling document. No other statements, representations, explanatory materials or examples, oral or written, may amend the Plan in any manner. The Plan shall be binding upon and enforceable against the Company and its successors and assigns.

16.Miscellaneous.
(a)Grants in Connection with Corporate Transactions and Otherwise. Nothing contained in this Plan shall be construed to (i) limit the right of the Committee to make Grants under this Plan in connection with the acquisition, by purchase, lease, merger, consolidation or otherwise, of the business or assets of any corporation, firm or association, including Grants to employees thereof who become Employees of the Company, or for other proper corporate purposes, or (ii) limit the right of the Company to grant stock options or make other awards outside of this Plan. Without limiting the foregoing, the Committee may make a Grant to an employee of another corporation who becomes an Employee by reason of a corporate merger, consolidation, acquisition of stock or property, reorganization or liquidation involving the Company or any of its Subsidiaries in substitution for a stock option or stock award grant made by such corporation. The terms and conditions of the substitute grants may vary from the terms and conditions required by the Plan and from those of the substituted stock incentives. The Committee shall prescribe the provisions of the substitute grants.
(b)Compliance with Law. The Plan, the exercise of Options and the obligations of the Company to issue or transfer shares of Company Stock under Grants shall be subject to all applicable laws and to approvals by any governmental or regulatory agency as may be required. With respect to Grantees subject to section 16 of the Exchange Act, it is the intent of the Company that the Plan and all transactions under the Plan comply with all applicable provisions of Rule 16b-3 or its successors under the Exchange Act. In addition, it is the intent of the Company that the Plan and applicable Grants under the Plan comply with the applicable provisions of section 162(m), section 409A and section 422 of the Code. To the extent that any legal requirement of section 16 of the Exchange Act, or section 162(m), section 409A and section 422 of the Code as set forth in the Plan ceases to be required under section 16 of the Exchange Act, or section 162(m), section 409A and section 422 of the Code, that Plan provision shall cease to apply. The Committee may revoke any Grant if it is contrary to law or modify a Grant to bring it into compliance with any valid and mandatory government regulation. The Committee may also adopt rules regarding the withholding of taxes on payments to Grantees. The Committee may, in its sole discretion, agree to limit its authority under this Section.
(c)Savings Provision. In the event any provision of this Plan shall be deemed to cause the application of the twenty percent (20%) penalty or immediate tax recognition under section 409A of the Code, the provision that causes either the application of the penalty or immediate tax recognition shall become null and void, and the Plan shall be construed and enforced as if the provision causing the negative tax consequences had never been contained herein.
(d)Governing Law. The validity, construction, interpretation and effect of the Plan and Grant Instruments issued under the Plan shall be governed and construed by and determined in accordance with the laws of Florida, without giving effect to the conflict of laws provisions thereof.
