Who is entitled to vote?

You may vote if you owned shares of the Company’s common stock as of the close of business on March 17, 2006. Each share of common stock is entitled to one vote. As of March 17, 2006, we had 3,306,184 shares of common stock outstanding.

How do I vote before the meeting?

If you are a registered shareholder, meaning that you hold your shares in certificate form, you have three voting options:

1. Over the Internet, which we encourage if you have Internet access, at the address shown on your proxy card;

2. By phone, by calling 1-800-690-6903 using any touch-tone telephone to transmit your voting instructions; or

3. By mail, by completing, signing and returning the enclosed proxy card.

If you hold your shares through an account with a bank or broker, your ability to vote by the Internet depends on their voting procedures. Please follow the directions that your bank or broker provides.

2

May I vote at the meeting?

You may vote your shares at the meeting if you attend in person. If you hold your shares through an account with a bank or broker, you must obtain a legal proxy from the bank or broker in order to vote at the meeting. A legal proxy is an authorization from your bank or broker to vote the shares it holds in its name for your benefit on the records of the Company’s transfer agent. Even if you plan to attend the meeting, we encourage you to vote your shares by proxy. You may vote by proxy through the Internet, by telephone or by mail.

Can I change my mind after I return my proxy?

You may change your vote at any time before the polls close at the conclusion of voting at the meeting. You may do this by (1) signing another proxy card with a later date and returning it to us before the meeting, (2) voting again over the Internet prior to 11:59 p.m., Eastern Time, on May 18, 2006, (3) voting again via the telephone prior to 11:59 p.m., Eastern Time, on May 18, 2006, or (4) voting at the meeting if you are a registered shareholder or have obtained a legal proxy from your bank or broker.

What if I return my proxy card but do not provide voting instructions?

Proxies that are signed and returned but do not contain instructions will be voted (1) FOR the election of the three nominees for Class III directors and the one nominee for Class II director, each as named herein, (2) FOR approval of the Company’s 2006 Stock Incentive Plan, (3) FOR the ratification of BDO Seidman, LLP as the Company’s independent registered public accounting firm for the fiscal year ended December 31, 2006, and (4) in accordance with the best judgment of the named proxies on any other matters properly brought before the meeting.

What does it mean if I receive more than one proxy card or instruction form?

It indicates that your shares are registered differently and are in more than one account. To ensure that all shares are voted, please either vote each account by telephone or on the Internet, or sign and return all proxy cards. We encourage you to register all your accounts in the same name and address. Those holding shares through a bank or broker should contact your bank or broker and request consolidation.

Will my shares be voted if I do not provide my proxy or instruction form?

If you are a registered shareholder and do not provide a proxy, you must attend the meeting in order to vote your shares. If you hold shares through an account with a bank or broker, your shares may be voted even if you do not provide voting instructions on your instruction form. Brokerage firms have the authority to vote shares for which their customers do not provide voting instructions on certain routine matters. The election of directors and the ratification of BDO Seidman, LLP as the Company’s independent registered public accounting firm for the fiscal year ended December 31, 2006 are considered routine matters for which brokerage firms may vote without specific instructions. The other proposal to be voted on at the

3

meeting is not considered “routine” under applicable rules. When a proposal is not a routine matter and the brokerage firm has not received voting instructions from the beneficial owner of the shares with respect to that proposal, the brokerage firm cannot vote the shares on that proposal. Shares that a broker is not authorized to vote are counted as “broker non-votes.”

How can I attend the meeting?

The meeting is open to all holders of the Company’s common stock as of March 17, 2006.

May shareholders ask questions at the meeting?

Yes. Representatives of the Company will answer questions of general interest at the end of the meeting.

How many votes must be present to hold the meeting?

Your shares are counted as present at the meeting if you attend the meeting and vote in person or if you properly return a proxy by Internet, telephone or mail. In order for us to conduct our meeting, a majority of our outstanding shares of common stock as of March 17, 2006 must be present in person or by proxy. This is referred to as a quorum. Abstentions and broker non-votes will be counted for purposes of establishing a quorum at the meeting.

How many votes are needed to approve the Company’s proposals?

The nominees receiving the highest number of “For” votes will be elected as directors. This number is called a plurality. Shares not voted will have no impact on the election of directors. The proxy given will be voted “For” each of the nominees for director unless a properly executed proxy card is marked “Withhold” as to a particular nominee or nominees for director.

With respect to the approval of the Company’s 2006 Stock Incentive Plan, broker non-votes will not be voted but an abstention will have the effect of a vote “Against” this proposal. Approval of the Company’s 2006 Stock Incentive Plan requires that a majority of the votes cast at the meeting be voted “For” the proposal and that the holders of a majority of the shares entitled to vote cast a vote, whether “For,” “Against” or “Abstain.”

The ratification of the appointment of BDO Seidman, LLP as the Company’s independent registered public accounting firm for the fiscal year ended December 31, 2006 requires that a majority of the votes cast at the meeting be voted “For” the proposal. A properly executed proxy card marked “Abstain” with respect to this proposal will not be voted.

BOARD OF DIRECTORS INFORMATION

What if a nominee is unwilling or unable to serve?

Each of the nominees listed in the Proxy Statement has agreed to serve as a director, if elected. If for some unforeseen reason a nominee becomes unwilling or unable to serve, proxies will be voted for a substitute nominee selected by the Board of Directors.

How are directors compensated?

All non-employee directors will receive an annual retainer fee (“Retainer Fee”) and a fee for each of the five regularly scheduled Board meetings attended per year (collectively, the “Director’s Fee”). Employee directors will not be eligible to receive the Retainer Fee or the Director’s Fee. The Retainer Fee and Director’s Fee for the upcoming year will be set at the last Board meeting during a calendar year. In addition to the Director’s Fee, all non-employee directors will receive reimbursement for travel and other related expenses incurred in attending Board meetings and committee meetings. For 2006, the Board set the Retainer Fee to be $7,500 and the Director’s Fee to be $1,000 for each Board meeting attended.

How does the Board determine which directors are independent?

The Board of Directors reviews the independence of each director yearly. During this review, the Board of Directors considers transactions and relationships between each director (and his or her immediate family and affiliates) and the Company and its management to determine whether any such relationships or transactions are inconsistent with a determination that the director is independent in light of applicable law, listing standards and the Company’s director independence standards. Based on this review, the Board affirmatively determined that all of the directors nominated for election at the meeting are independent of management, with the exception of Dr. Freer who is considered an inside director because of his employment as Chairman and COO of the Company and is therefore not considered an independent director. The Company believes that is meets the independence standards adopted by the Securities and Exchange Commission and the Nasdaq Capital Market.

What role does the Nominating Committee play in selecting nominees to the Board of Directors?

Two of the primary purposes of the Board’s Nominating Committee are to (i) develop and implement policies and procedures that are intended to ensure that the Board of Directors will be appropriately constituted and organized to meet its fiduciary obligations to the Company and its shareholders and (ii) identify individuals qualified to become members of the Board of Directors and to recommend to the Board of Directors the director nominees for the annual meeting of shareholders. The Nominating Committee is also responsible for considering candidates for membership on the Board of Directors submitted by eligible shareholders. The Nominating Committee’s charter, as well as other committee charters, is available on the Company’s website at www.cbi-biotech.com and in print upon request.

5

Are the members of the Nominating Committee independent?

Yes. All members of the Nominating Committee have been determined to be independent by the Board of Directors.

How does the Nominating Committee identify and evaluate nominees for director?

The Nominating Committee considers candidates for nomination to the Board of Directors from a number of sources. Current members of the Board of Directors are considered for re-election unless they have notified the Company that they do not wish to stand for re-election. The Nominating Committee also considers candidates recommended by current members of the Board of Directors, members of management or eligible shareholders. From time to time the Board may engage a firm to assist in identifying potential candidates, although the Company did not engage such a firm to identify any of the nominees for director proposed for election at the meeting.

The Nominating Committee evaluates all candidates for director, regardless of the person or firm recommending such candidate, on the basis of the length and quality of their business experience, the applicability of such candidate’s experience to the Company and its business, the skills and perspectives such candidate would bring to the Board of Directors and the personality or “fit” of such candidate with existing members of the Board of Directors and management.

What are the Nominating Committee’s policies and procedures for considering director considering director candidates recommended by shareholders?

The Nominating Committee will consider all candidates recommended by eligible shareholders. An eligible shareholder is a shareholder (or group of shareholders) who owns at least 5% of the Company’s outstanding shares and who has held such shares for at least one year as of the date of the recommendation. A shareholder wishing to recommend a candidate must submit the following documents to the Secretary of the Company at Commonwealth Biotechnologies, Inc., 601 Biotech Drive, Richmond, Virginia 23235:

6

Upon timely receipt of the required documents, the Company’s Secretary will determine if the shareholder submitting the recommendation is an eligible shareholder based on such documents. If the shareholder is not an eligible shareholder, the Nominating Committee may, but is not obligated to, evaluate the candidate and consider such candidate for nomination to the Board of Directors.

If the candidate is to be evaluated by the Nominating Committee, the Secretary will request a detailed resume, an autobiographical statement explaining the candidate’s interest in serving as a director of the Company, a completed statement regarding conflicts of interest, and a waiver of liability for background check from the candidate.

What are the minimum qualifications required to serve on the Company’s Board of Directors?

All members of the Board of Directors must possess the following minimum qualifications as determined by the Nominating Committee:

What other considerations does the Nominating Committee consider?

The Nominating Committee believes it is important to have directors from various backgrounds and professions in order to ensure that the Board of Directors has a wealth of experiences to inform its decisions. Consistent with this philosophy, in addition to the minimum standards set forth above, business and managerial experience and an understanding of financial statements and financial matters are very important.

7

How may shareholders communicate with the members of the Board of Directors?

Shareholders and others who are interested in communicating directly with members of the Board of Directors, including communication of concerns relating to accounting, internal accounting controls or audit matters, or fraud or unethical behavior, may do so by writing to the directors at the following address:

The complete text of the Code of Conduct is available on the Company’s web site at www.cbi-biotech.com and is also available in print upon request.

How often did the Board meet in fiscal 2005?

The Board of Directors met five times during fiscal 2005. The number of times that each Committee of the Board of Directors met is shown on pages 9-12. Each incumbent director attended at least 75% of the meetings of the Board of Directors and of the standing committees of which he or she was a member during fiscal 2005.

PROPOSAL TWO

APPROVAL OF THE COMMONWEALTH BIOTECHNOLOGIES, INC.

2006 STOCK INCENTIVE PLAN

(ITEM 2 ON THE PROXY CARD)

What am I voting on?

The Board of Directors adopted The Commonwealth Biotechnologies, Inc. 2006 Stock Incentive Plan (the “2006 Plan”) on November 18, 2005, subject to approval by the shareholders of the Company.

The Board of Directors believes that the 2006 Plan will advance the long-term success of the Company by encouraging stock ownership among key employees and members of the Board who are not employees (“Nonemployee Directors”).

How is the 2006 Plan administered?

The 2006 Plan is administered by the Compensation Committee of the Board of Directors (the “Committee”). Awards made to Nonemployee Directors will be approved by the Board. The 2006 Plan provides the Committee flexibility to design compensatory awards that are responsive to the Company’s needs. Subject to the terms of the 2006 Plan, the Committee has the discretion to determine the terms of each award. The Committee may delegate to one or more officers of the Company the authority to grant awards to participants who are not directors or executive officers of the Company. The Committee must fix the total number of shares that may be subject to grants made under this delegation.

What kind of awards may be granted?

Awards under the 2006 Plan may be in the form of stock options or shares of restricted or incentive stock.

Who is eligible to receive awards?

Employees of the Company and Nonemployee Directors may be selected by the Committee to receive awards under the 2006 Plan. The benefits or amounts that may be received by or allocated to participants under the 2006 Plan will be determined at the discretion of the Committee and are not presently determinable.

16

How many shares are available for issuance under the 2006 Plan?

The maximum number of shares as to which stock awards may be granted under the 2006 Plan is 300,000 shares. The fair market value of a share of the Company’s common stock on April 4, 2006 was $3.59, as reported on the Nasdaq Capital Market.

Are there limits on grants to individual participants or other grant limits?

Yes. No participant may receive awards during any one calendar year representing more than 50,000 shares of common stock. This limit is subject to adjustment by the Committee as provided in the 2006 Plan for stock splits, stock dividends, recapitalizations and other similar transactions or events.

Upon what terms may options be awarded?

Options may be either incentive stock options or nonqualified stock options, provided that only employees may be granted incentive stock options. The option may specify that the option price is payable (i) in cash, (ii) by the transfer to the Company of unrestricted stock, (iii) with any other legal consideration the Committee may deem appropriate or (iv) any combination of the foregoing. No stock option may be exercised more than 10 years from the date of grant. Each grant may specify a period of continuous employment or service with the Company or any subsidiary that is necessary before the stock option or any portion thereof will become exercisable and may provide for the earlier exercise of the option in the event of a change in control of the Company or similar event.

Upon what terms may restricted stock be awarded?

An award of restricted stock involves the immediate transfer by the Company to a participant of ownership of a specific number of shares of common stock in return for the performance of services. The participant is entitled immediately to voting, dividend and other ownership rights in such shares, subject to the discretion of the Committee. The transfer may be made without additional consideration from the participant. The Committee may specify performance objectives that must be achieved for the restrictions to lapse. Restricted stock must be subject to a “substantial risk of forfeiture” within the meaning of Code Section 83 for a period to be determined by the Committee on the grant date and any grant or sale may provide for the earlier termination of such risk of forfeiture in the event of a change of control of the Company or similar event.

Upon what terms may incentive stock be awarded?

An award of incentive stock granted under the 2006 Plan represents the right to receive a specific number of shares at the end of a specified deferral period. Any grant of deferred shares may be further conditioned upon the attainment of performance objectives. The grant may provide for the early termination of the deferral period in the event of a change in control of the Company or similar event. During the deferral period, the participant is not entitled to vote or receive dividends on the shares subject to the aware, but the Compensation Committee may

17

provide for the payment of dividend equivalents on a current or deferred basis. The grant of deferred shares may be made without any consideration from the participant other than the performance of future services.

Are awards made under the 2006 Plan transferable?

Except as provided below, no award under the 2006 Plan may be transferred by a participant other than by will or the laws of descent and distribution, and stock options and stock appreciation rights may be exercised during the participant’s lifetime only by the participant or, in the event of the participant’s legal incapacity, the guardian or legal representative acting on behalf of the participant. The Committee may expressly provide in an award agreement (other than an incentive stock option) that the participant may transfer the award to a spouse or lineal descendant, a trust for the exclusive benefit of such family members, a partnership or other entity in which all the beneficial owners are such family members, or any other entity affiliated with the participant that the Committee may approve.

When does the 2006 Plan terminate?

The 2006 Plan will terminate on the tenth anniversary of the date it is approved by shareholders, and no award will be granted under the plan after that date.

How can the 2006 Plan be amended?

The 2006 Plan may be amended by the Board of Directors, but without further approval by the shareholders of the Company no such amendment may increase the limitations set forth in the 2006 Plan on the number of shares that may be issued under the 2006 Plan or any of the limitations on awards to individual participants. The Board may condition any amendment on the approval of the shareholders if such approval is necessary or deemed advisable with respect to the applicable listing or other requirements of a national securities exchange or other applicable laws, policies or regulations.

What are the tax consequences of the 2006 Plan?

The following is a brief summary of certain of the federal income tax consequences of certain transactions under the 2006 Plan. This summary is not intended to be exhaustive and does not describe state or local tax consequences.

In general, an optionee will not recognize income at the time a nonqualified stock option is granted. At the time of exercise, the optionee will recognize ordinary income in an amount equal to the difference between the option price paid for the shares and the fair market value of the shares on the date of exercise. At the time of sale of shares acquired pursuant to the exercise of a nonqualified stock option, any appreciation (or depreciation) in the value of the shares after the date of exercise generally will be treated as capital gain (or loss).

18

An optionee generally will not recognize income upon the grant or exercise of an incentive stock option. If shares issued to an optionee upon the exercise of an incentive stock option are not disposed of in a disqualifying disposition within two years after the date of grant or within one year after the transfer of the shares to the optionee, then upon the sale of the shares any amount realized in excess of the option price generally will be taxed to the optionee as long-term capital gain and any loss sustained will be a long-term capital loss. If shares acquired upon the exercise of an incentive stock option are disposed of prior to the expiration of either holding period described above, the optionee generally will recognize ordinary income in the year of disposition in an amount equal to any excess of the fair market value of the shares at the time of exercise (or, if less, the amount realized on the disposition of the shares) over the option price paid for the shares. Any further gain (or loss) realized by the optionee generally will be taxed as short-term or long-term capital gain (or loss) depending on the holding period.

Subject to certain exceptions for death or disability, if an optionee exercises an incentive stock option more than three months after termination of employment, the exercise of the option will be taxed as the exercise of a nonqualified stock option. In addition, if an optionee is subject to federal “alternative minimum tax,” the exercise of an incentive stock option will be treated essentially the same as a nonqualified stock option for purposes of the alternative minimum tax.

A recipient of restricted stock generally will be subject to tax at ordinary income rates on the fair market value of the restricted stock (reduced by any amount paid by the recipient) at such time as the shares are no longer subject to a risk of forfeiture or restrictions on transfer for purposes of Code Section 83. However, a recipient who so elects under Code Section 83(b) within 30 days of the date of transfer of the restricted stock will recognize ordinary income on the date of transfer of the shares equal to the excess of the fair market value of the restricted stock (determined without regard to the risk of forfeiture or restrictions on transfer) over any purchase price paid for the shares. If a Section 83(b) election has not been made, any dividends received with respect to restricted stock that are subject at that time to a risk of forfeiture or restrictions on transfer generally will be treated as compensation that is taxable as ordinary income to the recipient.

To the extent that a participant recognizes ordinary income in the circumstances described above, the Company or subsidiary for which the participant performs services will be entitled to a corresponding deduction, provided that, among other things, the income meets the test of reasonableness, is an ordinary and necessary business expense, is not an “excess parachute payment” within the meaning of Code Section 280G and is not disallowed by the $1,000,000 limitation on certain executive compensation under Section 162(m) of the Internal Revenue Code.

None of the members of the Board of Directors who served on the Compensation Committee during the fiscal year ended December 31, 2005 were officers or employees of the Company or any of its subsidiaries or had any relationship with the Company requiring disclosure under SEC regulations.

(x) Rule 16b-3. Rule 16b-3 of the Act, including any corresponding subsequent rule or any amendments to Rule 16b-3 enacted after the effective date of the Plan.

(y) 10% Shareholder. A person who owns, directly or indirectly, stock possessing more than 10% of the total combined voting power of all classes of stock of the Company or an Affiliate. Indirect ownership of stock shall be determined in accordance with Code Section 424(d).

3. General. Awards of Options, Restricted Stock and Incentive Stock may be granted under the Plan. Options granted under the Plan may be Incentive Stock Options or Nonstatutory Stock Options.

4. Stock. Subject to Section 13 of the Plan, there shall be reserved for issuance under the Plan aggregate of 300,000 shares of Company Stock, which shall include authorized, but unissued, shares. The number of shares reserved for issuance as Incentive Stock Options under the Plan shall be an aggregate of 300,000 shares of Company Stock, which shall include authorized, but unissued shares. Shares allocable to Options granted under the Plan that expire or otherwise terminate unexercised and shares that are forfeited pursuant to restrictions on Restricted Stock or Incentive Stock awarded under the Plan may again be subjected to an Award under this Plan. For purposes of determining the number of shares that are available for Awards under the Plan, such number shall, if permissible under Rule 16b-3, include the number of shares surrendered by a Participant or retained by the Company (a) in connection with the exercise of an Option or (b) in payment of Applicable Withholding Taxes.

5. Eligibility.

(a) Any employee of, director of, or Consultant to the Company who, in the judgment of the Committee, has contributed or can be expected to contribute to the profits or growth of the Company is eligible to become a Participant. The Committee shall have the power and complete discretion to select eligible Participants and to determine for each Participant the terms, conditions and nature of the Award and the number of shares to be allocated as part of the Award; provided, however, that any award made to a member of the Committee must be approved by the Board. The Committee is

A-3

expressly authorized to make an Award to a Participant conditioned on the surrender for cancellation of an existing Award.

(b) The grant of an Award shall not obligate the Company to pay an employee any particular amount of remuneration, to continue the employment of the employee after the grant or to make further grants to the employee at any time thereafter.

(c) Non-employee directors and Consultants shall not be eligible to receive the Award of an Incentive Stock Option.

(d) The maximum number of shares with respect to which an Award may be granted in any calendar year to any employee during such calendar year shall be 50,000 shares of Company Stock.

6. Stock Options.

(a) Whenever the Committee deems it appropriate to grant Options, notice shall be given to the Participant stating the number of shares for which Options are granted, the Option price per share, whether the options are Incentive Stock Options or Nonstatutory Stock Options, and the conditions to which the grant and exercise of the Options are subject. This notice, when duly accepted in writing by the Participant, shall become a stock option agreement between the Company and the Participant.

(b) The Committee shall establish the exercise price of Options. The exercise price of an Incentive Stock Option shall be not less than 100% of the Fair Market Value of such shares on the Date of Grant, provided that if the Participant is a 10% Shareholder, the exercise price of an Incentive Stock Option shall be not less than 110% of the Fair Market Value of such shares on the Date of Grant. The exercise price of a Nonstatutory Stock Option Awards intended to be performance-bases for purposes of Code Section 162(m) shall not be less than 100% of the Fair Market Value of the shares of Company Stock covered by the Option on the Date of Grant.

(c) Options may be exercised in whole or in part at such times as may be specified by the Committee in the Participant’s stock option agreement. The Committee may impose such vesting conditions and other requirements as the Committee deems appropriate, and the Committee may include such provisions regarding a Change of Control or Corporate Change as the Committee deems appropriate.

(d) The Committee shall establish the term of each Option in the Participant’s stock option agreement. The term of an Incentive Stock Option shall not be longer than ten years from the Date of Grant, except that an Incentive Stock Option granted to a 10% Shareholder may not have a term in excess of five years. No option may be exercised after the expiration of its term or, except as set forth in the Participant’s stock option agreement, after the termination of the Participant’s employment. The Committee shall set forth in the Participant’s stock option agreement when, and under what circumstances, an Option may be exercised after termination of the Participant’s employment or period of service; provided that no Incentive Stock Option may be exercised after (i) three months from the Participant’s termination of employment with the Company for reasons other than Disability or death, or (ii) one year from the Participant’s termination of employment on account of Disability or death. The Committee may, in its sole discretion, amend a previously granted Incentive Stock Option to provide for more liberal exercise provisions, provided however that if the Incentive Stock Option as amended no longer meets the requirements of Code Section 422, and, as a result the Option no longer qualifies for

A-4

favorable federal income tax treatment under Code Section 422, the amendment shall not become effective without the written consent of the Participant.

(e) An Incentive Stock Option, by its terms, shall be exercisable in any calendar year only to the extent that the aggregate Fair Market Value (determined at the Date of Grant) of the Company Stock with respect to which Incentive Stock Options are exercisable by the Participant for the first time during the calendar year does not exceed $100,000 (the “Limitation Amount”). Incentive Stock Options granted under the Plan and all other plans of the Company and any parent or Subsidiary of the Company shall be aggregated for purposes of determining whether the Limitation Amount has been exceeded. The Board may impose such conditions as it deems appropriate on an Incentive Stock option to ensure that the foregoing requirement is met. If Incentive Stock Options that first become exercisable in a calendar year exceed the Limitation Amount, the excess Options will be treated as Nonstatutory Stock Options to the extent permitted by law.

(f) If a Participant dies and if the Participant’s stock option agreement provides that part or all of the Option may be exercised after the Participant’s death, then such portion may be exercised by the personal representative of the Participant’s estate during the time period specified in the stock option agreement.

(g) If a Participant’s employment or services is terminated by the Company for Cause, the Participant’s Options shall terminate as of the date of the misconduct.

7. Restricted Stock Awards.

(a) Whenever the Committee deems it appropriate to grant a Restricted Stock Award, notice shall be given to the Participant stating the number of shares of Restricted Stock for which the Award is granted and the terms and conditions to which the Award is subject. This notice, when accepted in writing by the Participant, shall become an Award agreement between the Company and the Participant. Certificates representing the shares shall be issued in the name of the Participant, subject to the restrictions imposed by the Plan and the Committee. A Restricted Stock Award may be made by the Committee in its discretion without cash consideration.

(b) The Committee may place such restrictions on the transferability and vesting of Restricted Stock as the Committee deems appropriate, including restrictions relating to continued employment and financial performance goals. Without limiting the foregoing, the Committee may provide performance or Change of Control or Corporate Change acceleration parameters under which all, or a portion, of the Restricted Stock will vest. Restricted Stock may not be sold, assigned, transferred, disposed of, pledged, hypothecated or otherwise encumbered until the restrictions on such shares shall have lapsed or shall have been removed pursuant to subsection (c) below.

(c) The Committee may provide in a Restricted Stock Award, or subsequently, that the restrictions will lapse if a Change of Control or Corporate Change occurs. The Committee may at any time, in its sole discretion, accelerate the time at which any or all restrictions will lapse or may remove restrictions on Restricted Stock as it deems appropriate.

(d) A Participant shall hold shares of Restricted Stock subject to the restrictions set forth in the Award agreement and in the Plan. In other respects, the Participant shall have all the rights of a shareholder with respect to the shares of Restricted Stock, including, but not limited to, the right to vote such shares and the right to receive all cash dividends and other distributions paid thereon. Certificates representing Restricted Stock shall bear a legend referring to the restrictions set forth in the

A-5

Plan and the Participant’s Award agreement. If stock dividends are declared on Restricted Stock, such stock dividends or other distributions shall be subject to the same restrictions as the underlying shares of Restricted Stock.

8. Incentive Stock Awards.

(a) Incentive Stock may be issued pursuant to the Plan in connection with incentive programs established from time to time by the Committee. The Committee shall establish such performance criteria as it deems appropriate as a prerequisite for the issuance of Incentive Stock. A Participant who is eligible to receive Incentive Stock will have no rights as a shareholder before receipt of the Incentive Stock certificates. Incentive Stock may be issued without cash consideration. A Participant’s interest in an incentive program or the contingent right to receive Incentive Stock may not be sold, assigned, transferred, pledged, hypothecated, or otherwise encumbered.

(b) The Committee may provide in the incentive program, or subsequently, that Incentive Stock will be issued if a Change of Control or Corporate Change occurs, even though the performance goals set by the Committee have not been met.

9. Method of Exercise of Options.

(a) Options may be exercised by giving written notice of the exercise to the Company, stating the number of shares the Participant has elected to purchase under the Option. Such notice shall be effective only if accompanied by the exercise price in full in cash; provided that, if the terms of an Option so permit, the Participant may (i) deliver Company Stock that the Participant has owned for at least six months (valued at Fair Market Value on the date of exercise), or (ii) deliver a properly executed exercise notice together with irrevocable instructions to a broker to deliver promptly to the Company, from the sale or loan proceeds with respect to the sale of Company Stock or a loan secured by Company Stock, the amount necessary to pay the exercise price and, if required by the Committee, Applicable Withholding Taxes. Unless otherwise specifically provided in the Option, any payment of the exercise price paid by delivery of Company Stock acquired directly or indirectly from the Company shall be paid only with shares of Company Stock that have been held by the Participant for more than six months (or such longer or shorter period of time required to avoid a charge to earnings for financial accounting purposes).

(b) Notwithstanding anything herein to the contrary, Awards shall always be granted and exercised in such a manner as to conform to the provisions of Rule 16b-3.

10. Applicable Withholding Taxes. Each Participant shall agree, as a condition of receiving an Award, to pay to the Company, or make arrangements satisfactory to the Company regarding the payment of, all Applicable Withholding Taxes with respect to the Award. Until the Applicable Withholding Taxes have been paid or arrangements satisfactory to the Company have been made, no stock certificates (or, in the case of Restricted Stock, no stock certificates free of a restrictive legend) shall be issued to the Participant. As an alternative to making a cash payment to the Company to satisfy Applicable Withholding Tax obligations, the Committee may establish procedures permitting the Participant to elect to (a) deliver shares of already owned Company Stock (subject to such restrictions as the Committee may establish, including a requirement that any shares of Company Stock so delivered shall have been held by the Participant for not less than six months) or (b) have the Company retain that number of shares of Company Stock that would satisfy all or a specified portion of the Applicable Withholding Taxes. Any such election shall be made only in accordance with procedures established by the Committee and in accordance with Rule 16b-3.

A-6

11. Nontransferability of Awards.

(a) In general, Awards, by their terms, shall not be transferable by the Participant except by will or by the laws of descent and distribution or except as described below. Options shall be exercisable, during the Participant’s lifetime, only by the Participant or by his guardian or legal representative.

(b) Notwithstanding the provisions of (a) and subject to federal and state securities laws, the Committee may grant Nonstatutory Stock Options that permit a Participant to transfer the Options to one or more immediate family members, to a trust for the benefit of immediate family members, or to a partnership, limited liability company, or other entity the only partners, members, or interest-holders of which are among the Participant’s immediate family members. Consideration may not be paid for the transfer of Options. The transferee of an Option shall be subject to all conditions applicable to the Option prior to its transfer. The agreement granting the Option shall set forth the transfer conditions and restrictions. The Committee may impose on any transferable Option and on stock issued upon the exercise of an Option such limitations and conditions as the Committee deems appropriate.

12. Termination, Modification, Change. If not sooner terminated by the Board, this Plan shall terminate at the close of business on the tenth anniversary of the Effective Date. No Awards shall be made under the Plan after its termination. The Board may terminate the Plan or may amend the Plan in such respects as it shall deem advisable; provided, that, if and to the extent required by Rule 16b-3, no change shall be made that increases the total number of shares of Company Stock reserved for issuance pursuant to Awards granted under the Plan (except pursuant to Section 13), expands the class of persons eligible to receive Awards, or materially increases the benefits accruing to Participants under the Plan, unless such change is authorized by the shareholders of the Company. Notwithstanding the foregoing, the Board may unilaterally amend the Plan and Awards as it deems appropriate to ensure compliance with Rule 16b-3 and to cause Incentive Stock Options to meet the requirements of the Code and regulations thereunder. Except as provided in the preceding sentence, a termination or amendment of the Plan shall not, without the consent of the Participant, adversely affect a Participant’s rights under an Award previously granted to him.

13. Change in Capital Structure.

(a) In the event of a stock dividend, stock split or combination of shares, spin-off, reclassification, recapitalization, merger or other change in the Company’s capital stock (including, but not limited to, the creation or issuance to shareholders generally of rights, options or warrants for the purchase of common stock or preferred stock of the Company), the number and kind of shares of stock or securities of the Company to be issued under the Plan (under outstanding Awards and Awards to be granted in the future), the exercise price of options, and other relevant provisions shall be appropriately adjusted by the Committee, whose determination shall be binding on all persons. If the adjustment would produce fractional shares with respect to any Award, the Committee may adjust appropriately the number of shares covered by the Award so as to eliminate the fractional shares.

(b) In the event the Company distributes to its shareholders a dividend, or sells or causes to be sold to a person other than the Company or a Subsidiary shares of stock in any corporation (a “Spinoff Company”) which, immediately before the distribution or sale, was a majority owned Subsidiary of the Company, the Committee shall have the power, in its sole discretion, to make such

A-7

adjustments as the Committee deems appropriate. The Committee may make adjustments in the number and kind of shares or other securities to be issued under the Plan (under outstanding Awards and Awards to be granted in the future), the exercise price of Options, and other relevant provisions, and, without limiting the foregoing, may substitute securities of a Spinoff Company for securities of the Company. The Committee shall make such adjustments as it determines to be appropriate, considering the economic effect of the distribution or sale on the interests of the Company’s shareholders and the Participants in the businesses operated by the Spinoff Company, and subject to the proviso that any such adjustments or new options shall not be made or granted, respectively, that would result in subjecting the Plan to variable plan accounting treatment. The Committee’s determination shall be binding on all persons. If the adjustment would produce fractional shares with respect to any Award, the Committee may adjust appropriately the number of shares covered by the Award so as to eliminate the fractional shares.

(c) To the extent required to avoid a charge to earnings for financial accounting purposes, adjustments made by the Committee pursuant to this Section 13 to outstanding Awards shall be made so that both (i) the aggregate intrinsic value of an Award immediately after the adjustment is not greater than or less than the Award’s aggregate intrinsic value before the adjustment and (ii) the ratio of the exercise price per share to the market value per share is not reduced.

(d) Notwithstanding anything in the Plan to the contrary, the Committee may take the foregoing actions without the consent of any Participant, and the Committee’s determination shall be conclusive and binding on all persons for all purposes. The Committee shall make its determinations consistent with Rule 16b-3 and the applicable provisions of the Code.

14. Change of Control.

(a) In the event of a Change of Control or Corporate Change, the Committee may take such actions with respect to Awards as the Committee deems appropriate. These actions may include, but shall not be limited to, the following: at the time the Award is made, provide for the acceleration of the vesting schedule relating to the exercise or realization of the Award so that the Award may be exercised or realized in full on or before a date initially fixed by the Committee;

(b) Provide for the purchase or settlement of any such Award by the Company for any amount of cash equal to the amount which could have been obtained upon the exercise of such Award or realization of a Participant’s rights had such Award been currently exercisable or payable;

(c) Make adjustments to Awards then outstanding as the Committee deems appropriate to reflect such Change of Control or Corporate Change; provided, however, that to the extent required to avoid a charge to earnings for financial accounting purposes, such adjustments shall be made so that both (i) the aggregate intrinsic value of an Award immediately after the adjustment is not greater than or less than the Award’s aggregate intrinsic value before the Award and (ii) the ratio of the exercise price per share to the market value per share is not reduced; or

(d) Cause any such Award then outstanding to be assumed, or new rights substituted therefore, by the acquiring or surviving legal entity in such Change of Control or Corporate Change.

15. Administration of the Plan.

(a) The Plan shall be administered by the Committee, who shall be appointed by the Board. If and to the extent required by Rule 16b-3, all members of the Committee shall be “Non-Employee Directors” as that term is defined in Rule 16b-3, and the Committee shall be comprised solely

A-8

of two or more “outside directors” as that term is defined for purposes of Code section 162(m). If any member of the Committee fails to qualify an “outside director” or (to the extent required by Rule 16b-3) a “Non-Employee Director,” such person shall immediately cease to be a member of the Committee and shall not take part in future Committee deliberations. The Committee from time to time may appoint members of the Committee and may fill vacancies, however caused, in the Committee.

(b) The Committee shall have the authority to impose such limitations or conditions upon an Award as the Committee deems appropriate to achieve the objectives of the Award and the Plan. Without limiting the foregoing and in addition to the powers set forth elsewhere in the Plan, the Committee shall have the power and complete discretion to determine (i) which eligible persons shall receive an Award and the nature of the Award, (ii) the number of shares of Company Stock to be covered by each Award, (iii) whether Options shall be Incentive Stock options or Nonstatutory Stock Options, (iv) the Fair Market Value of Company Stock, (v) the time or times when an Award shall be granted, (vi) whether an Award shall become vested over a period of time, according to a performance-based vesting schedule or otherwise, and when it shall be fully vested, (vii) the terms and conditions under which restrictions imposed upon an Award shall lapse, (viii) whether a Change of Control or Corporate Change exists, (ix) the terms of incentive programs, performance criteria and other factors relevant to the issuance of Incentive Stock or the lapse of restrictions on Restricted Stock or Options, (x) when Options may be exercised, (xi) whether to approve a Participant’s election with respect to Applicable Withholding Taxes, (xii) conditions relating to the length of time before disposition of Company Stock received in connection with an Award is permitted, (xiii) notice provisions relating to the sale of Company Stock acquired under the Plan, and (xiv) any additional requirements relating to Awards that the Committee deems appropriate. Notwithstanding the foregoing, no “tandem stock options” (where two stock options are issued together and the exercise of one option affects the right to exercise the other option) may be issued in connection with Incentive Stock Options.

(c) The Committee shall have the power to amend the terms of previously granted Awards so long as the terms as amended are consistent with the terms of the Plan and, where applicable, consistent with the qualification of an option as an Incentive Stock Option. The consent of the Participant must be obtained with respect to any amendment that would adversely affect the Participant’s rights under the Award, except that such consent shall not be required if such amendment is for the purpose of complying with Rule 16b-3 or any requirement of the Code applicable to the Award.

(d) The Committee may adopt rules and regulations for carrying out the Plan. The Committee shall have the express discretionary authority to construe and interpret the Plan and the Award agreements, to resolve any ambiguities, to define any terms, and to make any other determinations required by the Plan or an Award agreement. The interpretation and construction of any provisions of the Plan or an Award agreement by the Committee shall be final and conclusive. The Committee may consult with counsel, who may be counsel to the Company, and shall not incur any liability for any action taken in good faith in reliance upon the advice of counsel.

(e) A majority of the members of the Committee shall constitute a quorum, and all actions of the Committee shall be taken by a majority of the members present. Any action may be taken by a written instrument signed by all of the members, and any action so taken shall be fully effective as if it had been taken at a meeting.

16. Issuance of Company Stock. The Company shall not be required to issue or deliver any certificate for shares of Company Stock before (i) the admission of such shares to listing on any stock exchange on which the Company Stock may then be listed, (ii) receipt of any required registration or other qualification of such shares under any state or federal securities law or regulation that the

A-9

Company’s counsel shall determine is necessary or advisable, and (iii) the Company shall have been advised by counsel that all applicable legal requirements have been complied with. The Company may place on a certificate representing Company Stock any legend required to reflect restrictions pursuant to the Plan, and any legend deemed necessary by the Company’s counsel to comply with federal or state securities laws. The Company may require a customary written indication of a Participant’s investment intent. Until a Participant has been issued a certificate for the shares of Company Stock acquired, the Participant shall possess no shareholder rights with respect to the shares.

17. Rights Under the Plan. Title to and beneficial ownership of all benefits described in the Plan shall at all times remain with the Company. Participation in the Plan and the right to receive payments under the Plan shall not give a Participant any proprietary interest in the Company or any Affiliate or any of their assets. No trust fund shall be created in connection with the Plan, and there shall be no required funding of amounts that may become payable under the Plan. A Participant shall, for all purposes, be a general creditor of the Company. The interest of a Participant in the Plan cannot be assigned, anticipated, sold, encumbered or pledged and shall not be subject to the claims of his creditors.

18. Beneficiary. A Participant may designate, on a form provided by the Committee, one or more beneficiaries to receive any payments under Awards of Restricted Stock or Incentive Stock after the Participant’s death. If a Participant makes no valid designation, or if the designated beneficiary fails to survive the Participant or otherwise fails to receive the benefits, the Participant’s beneficiary shall be the first of the following persons who survives the Participant: (a) the Participant’s surviving spouse, (b) the Participant’s surviving descendants, per stirpes, or (c) the personal representative of the Participant’s estate.

19. Notice. All notices and other communications required or permitted to be given under this Plan shall be in writing and shall be deemed to have been duly given if delivered personally or mailed first class, postage prepaid, as follows: (a) if to the Company, at its principal business address to the attention of the Secretary; (b) if to any Participant, at the last address of the Participant known to the sender at the time the notice or other communication is sent.

20. Interpretation. The terms of this Plan and Awards granted pursuant to the Plan are subject to all present and future regulations and rulings of the Secretary of the Treasury relating to the qualification of Incentive Stock Options under the Code or compliance with Code section 162(m), to the extent applicable, and they are subject to all present and future rulings of the Securities and Exchange Commission with respect to Rule 16b-3. If any provision of the Plan or an Award conflicts with any such regulation or ruling, to the extent applicable, the Committee shall cause the Plan to be amended, and shall modify the Award, so as to comply, or if for any reason amendments cannot be made, that provision of the Plan and/or the Award shall be void and of no effect.
