PROPOSAL TWO:

APPROVAL OF THE FIRST AMENDMENT TO THE COMPANY’S 2002

STOCK INCENTIVE PLAN

The Board of Directors has adopted, subject to the approval of the shareholders, an amendment to the Company’s 2002 Stock Incentive Plan (the “Plan”) increasing the number of authorized shares under the Incentive Plan from 300,000 to 600,000 (the “Amendment”). The following summary is qualified in its entirety by the full text of the Plan, a copy of which is included as Exhibit A to this Proxy Statement and the Amendment, a copy of which is included Exhibit B to this Proxy Statement. You are encouraged to read the Plan and the Amendment carefully. Capitalized terms used in the summary are used as defined in the Plan.

Description of the Amendment

The Amendment provides for an increase in the number of shares of Common Stock reserved for issuance under the Plan from 300,000 to 600,000. This increase in the number of shares reserved for issuance is necessary to make available shares of Common Stock for issuance to the Company’s officers and employees to reward these individuals for their roles in the accomplishment of the Company’s long-term and short-term goals. The Plan is an essential part of the Company’s compensation and reward program for its officers and employees because awards under the Plan permit officers and employees to benefit from the Company’s continued growth. Accordingly, the Board of Directors believes that it is in the best interests of the Company to increase the number of shares authorized under the Plan to continue to provide officers and employees compensation and reward for their service to the Company.

Purpose

The purpose of the Plan is to promote the success of the Company by providing greater incentive to employees, directors and consultants to associate their personal interests with the long-term financial success of the Company and with growth in shareholder value. The Plan is designed to provide flexibility to the Company in its ability to motivate, attract, and retain the services of employees, directors and consultants upon whose judgment, interest, and special effort the successful conduct of the Company’s operations largely depends. The Plan terminates on March 27, 2012, unless sooner terminated by the Board of Directors.

Administration

The Plan is administered by the Company’s Compensation Committee. The Committee has the power to select Plan participants and to grant stock options and stock awards on terms the Committee considers appropriate. In addition, the Committee has the authority to interpret the Plan, to adopt, amend or waive rules or regulations for the Plan’s administration, and to make all other determinations for administration of the Plan.

11

Stock Options

Stock options granted under the Plan may be incentive stock options or non-statutory stock options. A stock option entitles the employee to purchase shares of Common Stock at the option price. The Committee will fix the option price at the time the stock option is granted, but in the case of an incentive stock option the exercise price cannot be less than 100% of the shares’ fair market value on the date of grant (or, in the case of an incentive stock option granted to a 10% shareholder of the company, 110% of the shares fair market value on the date of grant). The value in incentive stock options, based on the exercise price, that can be exercisable for the first time in any calendar year under the Plan or any other similar plan maintained by the Company is limited to $100,000. The option price may be paid in cash or with shares of Common Stock, or a combination of cash and Common Stock. Stock options may be exercised at such times and subject to such conditions as may be prescribed by the Committee, including the requirement that they will not be exercisable after ten years from the grant date.

Restricted Stock Awards

The Plan permits the grant of restricted stock awards (shares of Common Stock) to Plan participants. A restricted stock award may be, but is not required to be, forfeitable or otherwise restricted until certain conditions are satisfied. These conditions may include, for example, a requirement that the Plan participant complete a specified period of service or that certain objectives be achieved. Any restriction imposed on a restricted stock award will be determined by the Compensation Committee.

Transferability

In general, stock options and restricted stock awards granted may not be assigned, transferred, pledged or otherwise encumbered by a participant, other than by will or the laws of descent and distribution.

Shares Subject to the Plan

As proposed to be amended, up to 600,000 shares of Common Stock may be issued to Plan participants under the Plan. The maximum number of shares with respect to which stock options or restricted stock may be granted under the Plan in any calendar year to an employee is 50,000 shares. In general, if any stock option or restricted stock award granted terminates, expires or lapses for any reason other than as a result of being exercised, or if shares issued pursuant to the Plan are forfeited, the Common Stock subject to the stock option or restricted stock award will be available for further stock options and awards.

Changes in Capitalization and Similar Changes

In the event of any change in the outstanding shares of Common Stock by reason of any stock dividend, stock split, recapitalization or otherwise, the aggregate number of shares of Common Stock reserved under the Plan, and the terms, exercise price and number of shares of

12

any outstanding stock options or restricted stock awards will be equitably adjusted by the Committee in its discretion to preserve the benefits of the stock options and stock awards for Plan participants. For instance, a two-for-one stock split would double the number of shares reserved under the Plan. Similarly, for outstanding stock options it would double the number of shares covered by each stock option and reduce its exercise price by one-half.

Stock Price

On April     , 2004, the closing price of the Company’s Common Stock on the Nasdaq SmallCap Market was $         per share. Consequently, the aggregate market value of the securities underlying options granted pursuant to the Plan was approximately $        .

Vote Required

Approval of the Plan requires that more shares of Common Stock vote in favor of the Plan than against it.

Certain Federal Income Tax Consequences of the Plan

The federal income tax consequences under current federal income tax law are summarized in the following discussion which deals with the general tax principles applicable to the Plan, and is intended for general information only. In addition, the tax consequences described below are subject to the limitations of Section 162(m) of the Code, as discussed in further detail below. Alternative minimum tax and other federal taxes and foreign, state and local income taxes are not discussed, and may vary depending on individual circumstances and from locality to locality.

Nonqualified Stock Options. For federal income tax purposes, the recipient of non-qualified stock options granted under the Plan will not have taxable income upon the grant of the option, nor will the Company then be entitled to any deduction. Generally, upon exercise of non-qualified stock options the optionee will realize ordinary income and the Company will be entitled to a deduction in an amount equal to the difference between the option exercise price and the fair market value of a share of Common Stock at the date of exercise.

Incentive Stock Options. An optionee generally will not recognize taxable income upon either the grant or exercise of an incentive stock option. However, the amount by which the fair market value of the shares at the time of exercise exceeds the exercise price will be an “item of tax preference” for the optionee. Generally, upon the sale or other taxable disposition of the shares of Common Stock acquired upon exercise of an incentive stock option, the optionee will recognize income taxable as capital gains in an amount equal to the excess, if any, of the amount realized in such disposition over the option exercise price, provided that no disposition of the shares has taken place within either (a) two years from the date of grant of the incentive stock option or (b) one year from the date of exercise. If shares of Common Stock acquired upon exercise of the incentive stock option are sold or otherwise disposed of before the end of the one-year and two-year periods specified above, the difference between the incentive stock option exercise price and the fair market value of the shares on the date of exercise generally will be

13

taxable as ordinary income; the balance of the amount realized from such disposition, if any, generally will be taxed as capital gain. If shares of Common Stock are disposed of before the expiration of the one-year and two-year periods specified above and the amount realized is less than the fair market value of the shares at the date of exercise, the optionee’s ordinary income generally is limited to the excess, if any, of the amount realized in such disposition over the option exercise price paid. The Company (or other employer corporation) generally will be entitled to a tax deduction with respect to an incentive stock option only to the extent the optionee has ordinary income upon sale or other disposition of the shares of Common Stock acquired upon exercise of the option.

An option will only qualify as an incentive stock option to the extent that the aggregate fair market value of the shares with respect to which the option becomes exercisable for the first time in any calendar year is equal to or less than $100,000. For purposes of this rule, the fair market value of shares shall be determined as of the date the incentive stock option is granted. To the extent an incentive stock option is exercisable for shares in excess of this $100,000 limitation, the excess shares shall be taxable under the rules for “Nonqualified Stock Options,” described above.

Restricted Stock and Deferred Stock. A participant to whom restricted stock is issued will not have taxable income upon issuance and the Company will not then be entitled to a deduction, unless in the case of restricted stock an election is made under Section 83(b) of the Code. However, when restrictions on shares of restricted stock lapse, such that the shares are no longer subject to repurchase by the Company, the participant will realize ordinary income and the Company will be entitled to a deduction in an amount equal to the fair market value of the shares at the date such restrictions lapse, less the purchase price therefor. Similarly, when deferred stock vests and is issued to the participant, the participant will realize ordinary income and the Company will be entitled to a deduction in an amount equal to the fair market value of the shares at the date of issuance. The Code does not permit a Section 83(b) election to be made with respect to deferred stock.

Section 162(m). Under Section 162(m) of the Code, in general, income tax deductions of publicly-traded companies may be limited to the extent total compensation (including base salary, annual bonus, stock option exercises and non-qualified benefits) for certain executive officers exceeds $1 million in any one taxable year. However, under 162(m) of the Code, the deduction limit does not apply to certain “performance-based” compensation established by an independent compensation committee which conforms to certain restrictive conditions stated under the Code and related regulations. The Plan has been structured with the intent that options granted under the Plan may meet the requirements for “performance-based” compensation and Section 162(m) of the Code.

New Plan Benefits

For information regarding options and restricted stock awards granted to the Company’s executive officers, see the material under the heading “Executive Compensation”.

14

The number, amount and type of awards to be received by or allocated to eligible persons under the Plan cannot be determined at this time and the Administrator has not yet considered any other specific awards under the Plan.

The Compensation Committee believes stock option grants, restricted stock awards and the other forms of equity based compensation issuable under the Plan are an effective method of structuring compensation to focus on a longer term view of our performance and to help to ensure that the employees’ and the shareholders’ interests are aligned. Thus, in order to continue to provide proper incentives to the Company’s employees and to further align the interests of the employees with the Company’s shareholders, the Compensation Committee recommended the adoption of the Plan by the Board.

Under the Plan, the Company’s independent directors are eligible to receive nonqualified stock options in the discretion of the Compensation Committee.

Recommendation of the Board “For” This Proposal

The Board believes that the Plan will promote the Company’s interests and its shareholders and continue to enable the Company to attract, retain and reward persons important to its success and to provide incentives based on the attainment of corporate objectives and increases in stockholder value.

THE BOARD OF DIRECTORS HAS APPROVED AND RECOMMENDS THAT THE SHAREHOLDERS VOTE “FOR” THE PLAN AMENDMENT.

PROPOSAL THREE:

APPROVAL OF THE CREATION OF BLANK CHECK PREFERRED STOCK

The Board of Directors of the Company adopted a resolution unanimously approving and recommending to the Company’s shareholders for their approval an amendment to the Company’s Articles of Incorporation to provide for the creation of a new class of 100,000 shares of what is commonly known as “blank check” preferred stock. If this resolution is approved by the shareholders, it will be effected by the filing of Articles of Amendment to the Company’s Articles of Incorporation (the “Amendment”), which will occur promptly after this Special Meeting. The following discussion is qualified in its entirety by reference to the text of the proposed Amendment attached to this proxy statement as Exhibit C.

The Board of Directors believes the creation of the preferred stock is in the best interests of the Company and its shareholders and believes it advisable to authorize such shares to have them available for, among other things, possible issuance in connection with such activities as public or private offerings of shares for cash, dividends payable in stock of the Company, acquisitions of other companies, implementation of employee benefit plans, pursuit of financing opportunities and otherwise. The term “blank check” preferred stock refers to stock for which the designations, preferences, conversion rights, and cumulative, relative, participating, optional or other rights, including voting rights, qualifications, limitations or restrictions thereof, are determined by the Board of Directors of a company.

15

As such, the Board of Directors of the Company will, in the event of the approval of this proposal by the Company’s shareholders, be entitled to authorize the creation and issuance of 100,000 shares of preferred stock in one or more series with such limitations and restrictions as may be determined in the sole discretion of the Board of Directors, with no further authorization by shareholders required for the creation and issuance of the preferred stock. Any preferred stock issued would have priority over the Common Stock upon liquidation and might have priority rights as to dividends, voting and other features. Accordingly, the issuance of preferred stock could decrease the amount of earnings and assets allocable to or available for distribution to holders of Common Stock and adversely affect the rights and powers, including voting rights, of the Common Stock.

Generally, except in connection with a stockholder rights or “poison pill” plan, preferred stock would be issued to investors in connection with raising additional equity capital, and would typically contain terms and conditions intended to protect the interests of investors. Such terms and conditions typically would include preference over the holders of Common Stock in the proceeds of a sale or liquidation of the Company (including the distribution of assets upon a sale of substantially all of its assets and businesses) and priority dividend rights (which may include cumulative dividends), and might include special voting rights, special conversion rights and redemption rights. Such rights, either alone or in combination under particular circumstances, can provide the holders of preferred stock with a disproportionate share of current distribution of earnings by way of dividends, or of the proceeds of a sale or liquidation, or disproportionate rights of approval with respect to certain kinds of transactions, compared to those of the holders of Common Stock.

The Board of Directors does not believe that the approval of this proposal will have an anti-takeover effect, and, as noted below, has represented that such preferred stock will not be issued for such purpose. The Board of Directors and management believe that it is in the best interests of the Company and its shareholders to have the flexibility to raise additional capital or to pursue acquisitions to support the Company’s business plan, including the ability to authorize and issue preferred stock having terms and conditions satisfactory to investors or to acquisition candidates, including preferred stock which contains some features which could be viewed as having an anti-takeover effect or a potentially adverse effect on the holders of Common Stock. The Board of Directors and management of the Company represent that they will not, without prior stockholder approval, issue any preferred stock (i) the principal intent of which is any defensive or anti-takeover purpose or (ii) to implement any stockholder rights plan. No preferred stock will be issued to any individual or group for the purpose of creating a block of voting power to support management on a controversial issue. While the Company may consider issuing preferred stock in the future for purposes of raising additional capital or in connection with acquisition transactions, the Company presently has no agreements or understanding with any person to effect any such issuance, and the Company may never issue any preferred stock. Therefore, the terms of any preferred stock subject to this proposal cannot be stated or predicted with respect to any or all of the securities authorized.

16

VOTE REQUIRED

Approval of this proposal requires the affirmative vote of a majority of all of the outstanding shares of Common Stock present or represented and entitled to vote at the Special Meeting.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR APPROVAL OF PROPOSAL THREE.

PROPOSAL FOUR:

RATIFICATION OF APPOINTMENT OF INDEPENDENT AUDITORS

McGladrey & Pullen, LLP, the Company’s former independent auditors, resigned as the Company’s independent accountants on May 28, 2003. The Audit Committee then retained BDO Siedman, LLP to serve as the Company’s independent auditors for the fiscal year ending December 31, 2003.

During the two most recent fiscal years, there were no disagreements with McGladrey & Pullen, LLP on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements, if not resolved to McGladrey & Pullen’s satisfaction, would have caused McGladrey & Pullen to make reference to the subject matter of the disagreement(s) in connection with its report. The reports issued by McGladrey & Pullen, LLP on the Company did not contain any adverse opinion or disclaimer of opinion, but did contain an explanatory paragraph expressing uncertainty as to the registrant’s ability to continue as a going concern.

The Board is seeking stockholder approval of the Audit Committee’s selection of BDO Siedman, LLP as the Company’s independent auditors for the fiscal year ended December 31, 2004. Virginia law, under which law the Company was incorporated, does not require the approval of the selection of independent auditors by the Company’s shareholders; however, in view of the importance of the financial statements to shareholders, the Board of Directors deems it desirable that the Company’s shareholders pass upon the selection of auditors. In the event that shareholders disapprove of the selection, the Audit Committee will consider the selection of other auditors.

A representative of BDO Siedman, LLP will be present at the Annual Meeting. The Company has been informed that the representative does not intend to make any statement to the shareholders at the Annual Meeting, but will be available to respond to appropriate questions from shareholders. The Company does not expect a representative of McGladrey & Pullen, LLP to be present at the Annual Meeting.

REPORT OF THE AUDIT COMMITTEE

The Audit Committee is responsible for assisting the Board of Directors in fulfilling its oversight responsibilities pertaining to the Company’s accounting, auditing and financial reporting processes. Management is responsible for establishing and maintaining the Company’s system of internal controls and preparing financial statements in accordance with accounting principles generally accepted in the United States of America.

In fulfilling its oversight responsibilities and in accordance with its written charter adopted by the Board of Directors, the Committee reviewed the audited financial statements in the Company’s Annual Report to Shareholders with management, including a discussion of the quality, not just the acceptability, of the accounting principles, the reasonableness of significant judgments, and the clarity of disclosures in the financial statements.

The Committee reviewed with the independent auditors, who are responsible for expressing an opinion on the conformity of those audited financial statements with generally accepted accounting principles, their judgments as to the quality, not just the acceptability, of the Company’s accounting principles, and such other matters as are required to be discussed with the Committee under generally accepted auditing standards. In addition, the Committee has discussed with the independent auditors matters required to be discussed by SAS 61 and the auditors’ independence from management and the Company, including the written disclosures and letter received from the independent auditors as required by the Independence Standards Board Standard No. 1 and the compatibility of their non-audit services with maintaining their independence.

The Committee discussed with the Company’s internal and independent auditors the overall scope and plans for their respective audits. The Committee meets with the internal and independent auditors, with and without management present, to discuss the results of their examinations, their evaluations of the Company’s internal controls, and the overall quality of the Company’s financial reporting.

The Committee held four meetings during the fiscal year ended December 31, 2003.

In reliance on the reviews and discussions referred to in the foregoing paragraphs, the Committee recommended to the Board of Directors (and the Board has approved) that the audited financial statements be included in the Annual Report on Form 10-KSB for the year ended December 31, 2003 for filing with the Securities and Exchange Commission. The Committee and the Board have also recommended, subject to shareholder ratification, the selection of BDO Seidman, LLP as the Company’s independent auditors for the fiscal year ending December 31, 2004.

APPOINTMENT OF INDEPENDENT AUDITORS

During fiscal year 2002 and 2003, McGladrey & Pullen, LLP and BDO Seidman, LLP provided various audit, audit related and non-audit services to the Company as follows:

BDO Seidman LLP

Pre-Approval Policy

The Audit Committee has considered whether the provision of non-audit services by the Company’s principal auditor is compatible with maintaining audit independence and determined that the principal auditor should not be engaged for non-audit services. The Audit Committee’s policy is to pre-approve all audit services provided by the independent auditors. These services may include audit services, audit-related services, tax services and other services. Pre-approval is generally provided for up to one year and any pre-approval is detailed as to the particular service or category of services and is generally subject to a specific budget. The independent auditors and management are required to periodically report to the Audit Committee regarding the extent of services provided by the independent auditors in accordance with this pre-approval, and the fees for the services performed to date. The Audit Committee may also pre-approve particular services on a case-by-case basis.

Section 16(a) Beneficial Ownership Reporting Compliance

Based solely on a review of Forms 3 and 4 furnished to the Company under Rule 16a-3(e) promulgated under the Exchange Act, with respect to fiscal 2003, except as noted below, the Company is not aware of any director or executive officer of the Company who failed to file on a timely basis, as disclosed in such forms, reports required by Section 16(a) of the Exchange Act. Drs. Freer and Harris and Messrs. Reynolds and Brennan each failed to timely report one single transaction on Form 4. Mr. Causey failed to timely file a single transaction on Form 3. Such transactions have since been reported.

Certain Relationships and Related Transactions

In 2002, the Company completed a $302,000 private placement of Common Stock and warrants to purchase shares of Common Stock in a private placement. Each warrant has a five year term and a strike price of $0.90 per share. The following executive officers, directors and significant shareholders participated in the offering:

The Company believes that this transaction was made on terms no less favorable to the Company than could have been obtained from unaffiliated third parties. All future transactions between the Company and its officers, directors and principal shareholders will be approved in accordance with Virginia law by a majority of the Board of Directors, including a majority of the independent and disinterested directors of the Board of Directors, and will be on terms no less favorable to the Company than could be obtained from unaffiliated third parties.

20

Employment and Severance Agreements

On June 24, 1997, the Company entered into employment agreements with each of Dr. Freer, Dr. Harris and Mr. Reynolds. Each of these agreements has a term of five years and will be extended for successive one-year terms beginning on the first anniversary of its commencement, unless either the executive officer or the Company shall have given notice to the other of an election not to extend the term of the employment agreement. The employment agreements provide for base salaries of $165,000 for Dr. Freer and Dr. Harris and $120,000 for Mr. Reynolds, which are adjustable annually at the discretion of the Compensation Committee. Since the execution of the executive officers’ employment agreements in 1997, the Board of Directors has raised the executives’ salaries as follows: Dr. Freer - $181,500 (2003); Dr. Harris - $181,500 (2003) and Mr. Reynolds - $165,000 (2003). From November 2001 until November 2003, in an effort to conserve capital, the Board of Directors opted to defer a portion of the executives’ salaries. Currently, the Company’s executive officers have deferred the following amounts of salary: Dr. Harris - $51,299; Dr. Freer - $35,966 and Mr. Reynolds - $45,469. On November 16, 2003, the Company terminated this deferral arrangement upon the improvement of the Company’s financial condition.

In addition, the employment agreements provide the Company’s executive officers with annual bonuses equal to, in the aggregate, 15% of the Company’s pre-tax net income for the preceding fiscal year. Such bonuses will be paid within 30 days following the release of the Company’s annual audited financial statements. Under each of the employment agreements, the Company may terminate the executive officer’s employment at any time for “Cause” as such term is defined in the employment agreement, without incurring any continuing obligations to the executive officer. If the Company terminates an executive officer’s employment for any reason other than for “Cause” or if an executive officer terminates his or her employment for “Good Reason,” as such term is defined in the employment agreement, the Company will remain obligated to continue to provide the compensation and benefits specified in the executive officer’s employment agreement for the duration of what otherwise would have been the term of the employment agreement. In addition, each employment agreement contains non-competition provisions that prohibit each executive officer from competing with the Company or soliciting its employees under certain circumstances. A court may, however, determine that these non-competition provisions are unenforceable or only partially enforceable.

As of December 1, 1997, the Company entered into an employment agreement with Mr. Brennan. The agreement has a term of one year and will be extended for successive one-year terms unless either Mr. Brennan or the Company shall give notice to the other of an election not to extend the term of the employment agreement. The employment agreement provides a base salary of $65,000 per year, which amount is adjustable by the Company from time to time. Since the execution of this agreement, the Board of Directors has raised Mr. Brennan’s salary to $100,000 (2002). In addition, Mr. Brennan’s employment agreement provides Mr. Brennan with an annual bonus equal to 0.5% of the Company’s pre-tax net income for the preceding fiscal year. The agreement also contains non-competition provisions that prohibit Mr. Brennan from competing with the Company or soliciting its employees under certain circumstances. A court may, however, determine that these non-competition provisions are unenforceable or only partially enforceable.

21

The Company has entered into severance agreements with each of Dr. Freer, Dr. Harris and Mr. Reynolds. Each severance agreement (all of which are substantially similar) has an initial term of five years and will be extended for successive one-year periods beginning on the first anniversary of its commencement, unless either the executive officer or the Company shall have given notice to the other of an election not to extend the term of the severance agreement. If the employment of any of these executive officers is terminated (with certain exceptions) within 60 months following a “Change in Control,” as such term is defined in the severance agreement, the executive officer will be entitled to receive a cash payment equal to two times the annual salary for the most recent twelve-month period and three times the bonus paid with respect to such period. To the extent the aggregate benefits available to an executive officer, whether under his respective severance agreement or otherwise, exceed the limit of three times the executive’s average base compensation provided in Section 280G of the Internal Revenue Code of 1986, as amended, resulting in the executive officer incurring an excise tax under Section 4999 of the Internal Revenue Code of 1986, as amended, or any other taxes or penalties (other than ordinary income or capital gains taxes), the severance agreements require the Company to pay the executive officer an additional amount to cover any such excise taxes or penalties incurred. The Company will not be entitled to a deduction for the amount in excess of this limit.

As of April 10, 2000, the Company entered into a severance agreement with Mr. Brennan. This agreement has a term of one year and will be extended for successive one-year periods, unless either Mr. Brennan or the Company shall give notice to the other of an election not to extend the term of the severance agreement. If Mr. Brennan’s employment is terminated (with certain exceptions) within 60 months following a “Change in Control,” as such term is defined in the severance agreement, Mr. Brennan will be entitled to receive a cash payment equal to two times his annual salary at the rate in effect immediately prior to the termination.

The amount and nature of such consideration will be reviewed annually by the Compensation Committee. In addition to the Director’s Fee, all directors receive reimbursement for travel and other related expenses incurred in attending Board meetings and committee meetings. Since November 2001, the Company’s directors have opted to defer cash payment of all Director’s Fees and travel reimbursements.

4. Stock.

Subject to Section 12 of the Plan, there shall be reserved for issuance under the Plan an aggregate of 300,000 shares of Company Stock, which may 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 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 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 (including an employee of, director of, or consultant to an affiliate of 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, as provided in Section 14, 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 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.

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 exercise price per share, whether the options are Incentive Stock Options or Nonstatutory Stock Options,

A-4

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 not be less than 110% of the Fair Market Value of such shares on the Date of Grant. The exercise price of Nonstatutory Stock Option Awards intended to be performance-based for purposes of Code Section 162(m) shall not be less than 100% of the Fair Market Value of such shares on the Date of Grant.

(c) Subject to subsection (d) below, 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 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 shall 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 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.

A-5

(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. 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 previously acquired and owned (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) The Company may place on any certificate representing Company Stock issued upon the exercise of an Option any legend deemed desirable by the Company’s counsel to comply with federal or state securities laws. The Company may require of the Participant a customary indication of his or her investment intent. A Participant shall not possess shareholder rights with respect to shares acquired upon the exercise of an Option until the Participant has made any required payment, including payment of Applicable Withholding Taxes, and the Company has issued a certificate for the shares of Company Stock acquired.

(c) 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.

8. 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, the Date of Grant, and the terms and conditions to which the Award is subject. 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.

A-6

(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 acceleration parameters under which all, or a portion, of the Restricted Stock will vest on the Company’s achievement of established performance objectives. 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 shall establish as to each Restricted Stock Award the terms and conditions upon which the restrictions on transferability set forth in paragraph (b) above shall lapse. Such terms and conditions may include, without limitation, the passage of time, the meeting of performance goals, the lapsing of such restrictions as a result of the Disability, death or retirement of the Participant, or the occurrence of a Change of Control.

(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 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.

9. 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 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 to avoid a charge to earnings for financial accounting purposes and in accordance with Rule 16b-3.

10. 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.

A-7

(b) Notwithstanding the provisions of (a) and subject to federal and state securities laws, the Committee may grant or amend 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.

11. Termination, Modification, Change.

If not sooner terminated by the Board, this Plan shall terminate at the close of business on March 27, 2012. 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, unless authorized by the Company’s shareholders, no change shall be made that (a) increases the total number of shares of Company Stock reserved for issuance pursuant to Awards granted under the Plan (except pursuant to Section 12), (b) expands the class of persons eligible to receive Awards, (c) materially increases the benefits accruing to Participants under the Plan, or (d) otherwise requires shareholder approval under the Code, Rule 16b-3, or the rules of a domestic exchange on which Company Stock is traded. 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.

12. Change in Capital Structure.

(a) In the event of a stock dividend, stock split or combination of shares, spin-off, recapitalization or merger in which the Company is the surviving corporation, 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

A-8

discretion, to make such 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. 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) 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.

(d) 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 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.

13. Change of Control.

In the event of a Change of Control of the Company, 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:

(a) 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 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 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

A-9

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

14. Administration of the Plan.

(a) The Plan shall be administered by the Committee, who shall be appointed by the Board. If no Committee is appointed, the Plan shall be administered by the Board. To the extent required by Rule 16b-3, all Awards shall be made by members of the Committee who are “Non-Employee Directors” as that term is defined in Rule 16b-3, or by the Board. Awards that are intended to be performance-based for purposes of Code section 162(m) shall be made by a Committee, or subcommittee of the Committee, comprised solely of two or more “outside directors” as that term is defined for purposes of Code section 162(m).

(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 exists, (ix) factors relevant to 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

A-10

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.

15. 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, electronically, 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.

16. Interpretation and Governing Law. The terms of this Plan and Awards granted pursuant to the Plan shall be governed, construed and administered in accordance with the laws of the State of Virginia. The Plan and Awards are subject to all present and future applicable provisions of the Code and, to the extent applicable, 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 Code provision or ruling, 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 or the Award shall be void and of no effect.

IN WITNESS WHEREOF, our Company has caused this Plan to be adopted this 27th day of March, 2002.

(a) Each share of Common Stock shall be entitled to one vote on all matters submitted to a vote at any meeting of the Corporation’s shareholders.

(i) Any corporate action, except the election of directors, an amendment or restatement of these Articles, a merger, a statutory share exchange, the sale or other disposition of all or substantially all the Corporation’s assets otherwise than in the usual and regular course of business, or dissolution shall be approved at a meeting at which a quorum of the Corporation’s shareholders is present if the votes cast in favor of the action exceed the votes cast against the action;

(ii) Directors shall be elected by a plurality of the votes cast by the holders of the Common Stock entitled to vote in the election at a meeting at which a quorum is present;

(iv) Any transaction with the Corporation or any subsidiary that constitutes or involves an affiliated transaction, as defined in Section 13.1-725 of the Virginia Stock Corporation Act, as in effect on the effective date of these Articles, shall be approved by at least two-thirds of the votes entitled to be cast by the holders of the Common Stock;

(c) Dividends may be paid upon the Common Stock out of any assets of the Corporation available for dividends remaining after full dividends on the outstanding Preferred Stock (as defined below) at the dividend rate or rates therefor, together with the full additional amount required by any participation right, with respect to all past dividend periods and the current dividend period shall have been paid or declared and set apart for payment and all mandatory sinking funds payment that shall have become due in respect of any series of the Preferred Stock shall have been made.

2. The number of shares of preferred stock which the Corporation shall have the authority to issue shall be 100,000 shares, without par value per share (“Preferred Stock”).

(a) The Board of Directors is hereby empowered to cause any class of the Preferred Stock of the Corporation to be issued in series with such of the variations permitted by Subdivisions (i) - (xi) of this Section below, as shall be determined by the Board of Directors. The shares of Preferred Stock of different classes or series may vary as to:

(i) the designation of such class or series, the number of shares to constitute such class or series and the stated value thereof;

C-2

(ii) whether the shares of such class or series shall have voting rights in addition to any voting rights provided by law, and if so, the terms of such voting rights, which (x) may be general or limited, and (y) may permit more than one vote per share;

(iii) the rate or rates (which may be fixed or variable) at which dividends, if any, are payable on such class or series, whether any such dividends shall be cumulative, and if so, from what dates, the conditions and dates upon which such dividends shall be payable, the preference or relation which such dividends shall bear to the dividends payable on any shares of stock of any other class or any other series of such class;

(iv) whether the shares of such class or series shall be subject to redemption by the Corporation, and if so, the times, prices and other conditions of such redemption;

(v) the amount or amounts payable upon shares of such class or series upon, and the rights of the holders of such class or series in, the voluntary or involuntary liquidation, dissolution or winding up, or any distribution of the assets of, the Corporation;

(vi) whether the shares of such class or series shall be subject to the operation of a retirement or sinking fund, and if so, the extent to and manner in which any such retirement or sinking fund shall be applied to the purchase or redemption of the shares of such series for retirement or other corporate purposes and the terms and provisions relative to the operation thereof;

(vii) whether the shares of such series shall be convertible into, or exchangeable for, shares of stock of any other class or any other series of such class or any other securities (including Common Stock) and, if so, the price or prices or the rate or rates of conversion or exchange and the method, if any, of adjusting the same, and any other terms and conditions of conversion or exchange;

(viii) the limitations and restrictions, if any, to be effective while any shares of such class or series are outstanding upon the payment of dividends or the making of other distributions on, and upon the purchase, redemption or other acquisition by the Corporation of, the Common Stock or shares of stock of any other class or any other series of such class;

(ix) the conditions or restrictions, if any, upon the creation of indebtedness of the Corporation or upon the issue of any additional stock, including additional shares of such class or series or of any other series of such class or of any other class;

(x) the ranking (be it pari passu, junior or senior) of each class or series as to the payment of dividends, the distribution of assets and all other matters; and

C-3

(xi) any other powers, preferences and relative, participating, optional and other special rights, and any qualifications, limitations and restrictions thereof, insofar as they are not inconsistent with the provisions of these Articles of Incorporation, to the full extent permitted in accordance with the laws of the Commonwealth of Virginia.

(b) In the event of any liquidation, dissolution or winding up of the Corporation, after there shall have been paid to or set aside for the holders of the Preferred Stock the full preferential amounts to which they are respectively entitled under the provisions of these Articles of Incorporation applicable to the Preferred Stock, the holders of the Preferred Stock shall have no claim to any of the remaining assets of the Corporation.

(c) The powers, preferences and relative, participating, option and other special rights of each class or series of Preferred Stock and the qualifications, limitations or restrictions thereof, if any, may differ from those of any and all other classes and series at any time outstanding. All shares of Preferred Stock of each series shall be equal in all respects.

3. In the event of any voluntary or involuntary liquidation, dissolution or winding up of the Corporation, if the assets of the Corporation available for distribution to its shareholders shall be insufficient to pay in full all amounts to which the holders of Preferred Stock and any other stock of any class ranking on a parity as to liquidation preference are entitled, the amount available for distribution to shareholders shall be shared by the holders of all such classes and any series thereof pro rata according to the preferential amounts to which the shares of each such series or class are entitled. For the purposes of this Section 3, a consolidation or merger of the Corporation with any other corporation, or the sale, transfer or lease of all or substantially all its assets shall not constitute or be deemed a liquidation, dissolution, or winding up of the Corporation.

4. Any and all shares of Preferred Stock and Common Stock of the Corporation, at the time authorized but not issued and outstanding, may be issued and disposed of by the Board of Directors of the Corporation in any lawful manner, consistently, in the case of shares of Preferred Stock, with the requirements set forth in the provisions of these Articles of Incorporation applicable to the Preferred Stock, at any time and from time to time, for such considerations as may be fixed by the Board of Directors of the Corporation.

5. No holder of shares of any class of stock of the Corporation shall have any preemptive or preferential right to purchase or subscribe to (i) any shares of any class of the Corporation, whether now or hereafter authorized; (ii) any warrants, rights, or options to purchase any such shares; or (iii) any securities or obligations convertible into any such shares or into warrants, rights or options to purchase any such shares, except as may be provided for in any written agreement entered into by the Corporation with any such holder or holders of shares. 6. Any class of stock of the Corporation shall be deemed to rank — (a) prior to another class either as to dividends or upon liquidation, if the holders of such class shall be entitled to the receipt of dividends or of amounts distributable on liquidation, dissolution or winding up, as the case may be, in preference or priority to holders of such other class; (b) on a parity with another class either as to dividends or upon liquidation, whether or not the dividend rates, dividend payment dates, or redemption or liquidation prices per share thereof are different from those of such

C-4

others, if the holders of such class of stock shall be entitled to receipt of dividends or amounts distributable upon liquidation, dissolution or winding up, as the case may be, in proportion to their respective dividend rates or prices, without preference or priority one over the other with respect to the holders of such other class; and (c) junior to another class either as to dividends or upon liquidation, if the rights of the holders of such class shall be subject or subordinate to the rights of the holders of such other class in respect of the receipt of dividends or of amounts distributable upon liquidation, dissolution or winding up, as the case may be.
