Board of Directors

Our Certificate of Incorporation and By-laws provide that our business is to be managed by or under the direction of our Board of Directors. Our Board of Directors is divided into three classes for purposes of
election. One class is elected at each Annual Meeting of stockholders to serve for a three-year term. Our Board of Directors currently consists of six members, classified into three classes as follows:



| |  |  | The Class I directors are Dr. Hecht, Dr. Noonan and Mr. Beery, and their term will end at the 2007 annual meeting of stockholders;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------

Any additional directorships resulting from an increase in the number of directors will be distributed among the three classes so that, as nearly as
possible, each class will consist of one-third of the directors.

Audit Committee of the Board of Directors

Our Audit Committee currently has three members, Mr. Beery, Dr. Hecht and Ms. Williams (Chairperson). Our Audit Committees role and
responsibilities are set forth in a written charter and include the authority to retain and terminate the services of our independent registered public accounting firm, review annual consolidated financial statements, consider matters relating to
accounting policy and internal controls and review the scope of annual audits. All members of the Audit Committee satisfy the current independence standards promulgated by the Securities and Exchange Commission and by the Nasdaq Stock Market LLC, as
such standards apply specifically to members of audit committees. Our Board of Directors has determined that Ms. Williams is an audit committee financial expert, as the Securities and Exchange Commission has defined that term in
Item 401 of Regulation S-K.

Nominations for Directors

We do not currently have a standing Nominating Committee since our Board of Directors determined that the independent members of the Board of Directors adequately fulfill the obligations of a nominating
committee without the need of incurring additional costs of committee meetings.

The Board of Directors considers recommendations
of potential candidates from current directors, management and stockholders. Stockholders nominations for directors must be made in writing and include the nominees written consent to the nomination and sufficient background information
on the candidate to enable the Board of Directors to assess his or her qualifications. Nominations must be addressed to the Chairman of the Board in care of our Secretary at our headquarters address listed below, and generally must be received no
later than 60 days nor earlier than 90 days prior to the first anniversary of the preceding years annual meeting, in order to be considered for the next annual election of Directors.

The Compensation Committee believes that the most effective executive compensation program is one that is designed to reward the achievement of specific annual, long-term and strategic goals by the Company, and which
aligns executives interests with those of the stockholders by rewarding performance at or above established goals, with the ultimate object of improving stockholder value. The philosophy of the Compensation Committee is to evaluate both
performance and compensation to ensure that we maintain our ability to attract and retain superior employees in key positions and that compensation provided to key employees remains competitive relative to the compensation paid to similarly situated
executives of our peer companies. To that end, the Compensation Committee believes executive compensation packages should include both cash and equity-based compensation that reward performance as measured against established goals.

Setting Executive Compensation

Management
develops our compensation plans by utilizing publicly available compensation data as well as subscription survey data for national and regional companies in the biopharmaceutical and laboratory services industries. We believe that the practices of
these groups of companies provide us with appropriate compensation benchmarks, because these groups of companies are in similar businesses and tend to compete with us for executives and other employees. For benchmarking executive compensation, we
typically review the compensation data we have collected from these groups of companies, as well as a subset of the data from those companies that have a similar number of employees as our Company. For purposes of determining executive compensation,
we have not engaged consultants to help us analyze this data or to compare our compensation programs with the practices of the companies represented in the compensation data we review. We have, however, in prior years engaged a consultant to assist
us in assessing the compensation of our technical staff.

Based on managements analyses and recommendations, the Compensation
Committee has approved a pay-for-performance compensation philosophy, which is intended to establish base salaries and total executive compensation (taking into consideration the executives experience and abilities) that are competitive with
those companies with a similar number of employees represented in the compensation data we review.

We work within the framework of this
pay-for-performance compensation philosophy to determine each component of an executives initial compensation package based on numerous factors, including:



| |  |  | the individuals particular background, track record and circumstances, including training and prior relevant work experience;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------

| |  |  | the individuals role with us and the compensation paid to similar persons in the companies represented in the compensation data that we review;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------

| |  |  | the demand for individuals with the individuals specific expertise and experience at the time of hire;
| | - |  | -------------------------------------------------------------------------------------------------------

| |  |  | performance goals and other expectations for the position; and
| | - |  | --------------------------------------------------------------

| |  |  | uniqueness of industry skills.

The Compensation Committee typically implements a program of annual performance reviews under which
annual performance goals are determined and set forth in writing during the first and second quarters of each year. Annual corporate goals are proposed by management and approved by the Board of Directors during the first quarter of each year. These
corporate goals target the achievement of specific annual objectives, which are both financial and strategic. Annual facility and individual goals focus on contributions which facilitate the achievement of the corporate goals and are typically set
during the first and second quarters of each calendar year. Goals for each facility are developed by the President and Chief Executive Officer and key executives of the Company with input from each facility director. Individual goals are developed
by each employee and the employees manager and are designed to be in line with the annual corporate goals as well as the goals of the facility at which the employee works. Annual salary increases, annual bonuses, and annual equity awards
granted to our employees are tied to the achievement of these corporate, facility and each individuals performance goals.

We
regularly assess the written goals to determine corporate, facility and individual progress against the previously established goals and may make any adjustments to the goals for the remainder of the year based on changing circumstances.

During the first calendar quarter, we typically evaluate corporate, facility and individual performance against the written goals for the recently
completed year. Consistent with our compensation philosophy, each employees supervisor prepares a written evaluation of the employees performance. This process leads to a recommendation for annual employee salary increases and annual
equity awards and bonuses, if any, which is then reviewed and approved, as appropriate, by management and the Compensation Committee. In addition to rating performance, during the annual review process, facility managers may also determine if any
employee should be promoted and, if there are significant differences in how a person is compensated as compared to industry benchmarks, proposes any additional adjustments to be made. Following his review of executive officers, our President and
Chief Executive Officer prepares compensation recommendations for executive officers and other certain employees which are reviewed and finalized with our Director of Human Resources and submitted with recommendations to the Compensation Committee,
which may accept or adjust the recommendations. In the case of the President and Chief Executive Officer, his individual performance evaluation is conducted by the Compensation Committee, which determines his compensation changes and awards, if any.
For all employees, including our executive officers, annual base salary increases, annual equity awards and annual bonuses, to the extent granted, are implemented during the first or second calendar quarters of the year.

Although the Compensation Committee intends to implement the foregoing procedure for the fiscal year ending December 31, 2007 and thereafter,
because of the significant changes in management that occurred in 2006, including without limitation the departure of our former President and Chief Executive Officer and our former Chief Financial Officer and the hiring of our current President and
Chief Executive Officer, the Compensation Committee did not set performance goals or review performance against such goals for executive officers for the fiscal year ended December 31, 2006. However, as discussed below, with the exception of
the 100,000 shares of our common stock issued to our current President and Chief Executive Officer, no annual performance bonuses were paid to our President and Chief Executive Officer or any other named executive officer with respect to the fiscal
year ended December 31, 2006.

2006 Executive Compensation Components

For the fiscal year ended December 31, 2006, the principal components of compensation that our named executive officers are eligible to receive were:



| |  |  | Base salary;
| | - |  | ------------



| |  |  | Performance-based incentive compensation (annual bonus);
| | - |  | --------------------------------------------------------



| |  |  | Long-term equity incentive compensation;
| | - |  | ----------------------------------------



| |  |  | Signing bonus;
| | - |  | --------------



| |  |  | Retirement and other benefits (non-qualified deferred compensation);
| | - |  | --------------------------------------------------------------------



| |  |  | Perquisites and other personal benefits.
| | - |  | ----------------------------------------

Base Salary

Base salaries for our executives are established based on the scope of their responsibilities and their prior
relevant background, track record, training and experience, taking into account competitive market compensation paid by the companies represented in the compensation data we review for similar positions and the overall market demand for such
executives at the time of hire. As with total executive compensation, we believe that executive base salaries should be competitive with the range of salaries for executives in similar positions and with similar responsibilities in the companies of
similar size to us represented in the compensation data we review. An executives base salary is also evaluated together with other components of the executives other compensation to ensure that the executives total compensation is
in line with our overall compensation philosophy.

##### Table of Contents

Our President and Chief Executive Officer was recruited and hired by our Board of Directors during the
first quarter of 2006. The salary and other compensation for our President and Chief Executive Officer was established in arms-length negotiations between the President and Chief Executive Officer and our Board of Directors, taking into account his
extensive experience, track record, the Companys request that he relocate to the Princeton, New Jersey area, the timing of such relocation and other factors.

Base salaries are reviewed annually as part of our annual performance review program, and increased for merit reasons, based on certain considerations, including executives success in meeting or exceeding
individual performance objectives and an assessment of whether significant corporate and applicable facility goals were achieved. If necessary, we also realign base salaries with market levels for the same positions in the companies of similar size
to us represented in the compensation data we review, if we identify significant market changes in our data analysis. Additionally, we adjust base salaries as warranted throughout the year for promotions or other changes in the scope or breadth of
an executives role or responsibilities. In 2005, we engaged a consultant to assist us in assessing the compensation of our technical staff.

Annual Bonus

Our compensation program includes eligibility for an annual performance-based cash bonus in the case of
executives and certain other employees. The amount of the cash bonus depends on the level of achievement of the stated corporate, facility and individual performance goals, with a target bonus generally set as a percentage of base salary. All
executives, other than our President and Chief Executive Officer, and certain non-executive employees are eligible for annual performance-based cash bonuses in amounts that range from 10%-40% of their base salaries, as set forth in their employment
offer letters and in accordance with Company policies. In its discretion, the Compensation Committee may, however, award bonus payments to our executives above or below the amounts specified in their respective offer letters. As provided in his
employment agreement, our President and Chief Executive Officer is eligible for an annual performance-based cash bonus of 50% of his base salary. In its discretion, the Compensation Committee and Board of Directors may, however, award a bonus
payment above or below this target amount.

In 2006, no annual cash bonuses were paid to our former President and Chief Executive Officer
or any other named executive officer with respect to the fiscal year ended December 31, 2005. In 2007, no annual cash bonuses were paid to our President and Chief Executive Officer, any other named executive officer or any other employee with
respect to the fiscal year ended December 31, 2006.

We are in the process of evaluating our use of annual bonuses after executives or
other non-executive employees join our Company and in particular whether such bonuses provide proper incentives to executives and other non-executives of the Company.

Long-Term Equity Incentive Compensation

We believe that long-term performance is
achieved through an ownership culture that encourages long-term participation by our employees in equity-based awards. Our 2005 Amended and Restated Stock Plan allows the grant to employees of stock options, restricted stock grants, stock grants and
other equity-based awards. We currently make initial equity awards of stock options to new executive and certain non-executive employees in connection with their employment with the Company. Annual grants of options, if any, are approved by the
Compensation Committee.

Initial Equity Incentives

Initial stock option awards. Executives and certain non-executive employees who join us are awarded initial stock option grants. These grants
have an exercise price equal to the fair market value of our common stock on the later of the grant date or the date the employee joins us, and they typically vest on a monthly basis over four years. The initial stock option awards are intended to
provide the executive with incentive to build value in the organization over an extended period of time. The size of the initial stock option award is also reviewed in light of the executives track record, base salary, other compensation and
other factors to ensure that the executives total compensation is in line with our overall compensation philosophy.

In connection
with the employment of our current President and Chief Executive Officer, we granted Mr. Bologna options to acquire 600,000 shares of our common stock at an exercise price of $4.53, which options vest monthly over four years. The number of
shares granted to Mr. Bologna was determined in arms-length negotiations between Mr. Bologna and our Board of Directors, taking into account his extensive experience, track record, the Companys request that he relocate to the
Princeton, New Jersey area, the timing of such relocation and other factors.

##### Table of Contents

Initial stock awards. We have not made initial grants of stock to any of our employees. However,
we may make grants of stock, either restricted or fully vested, to executives and certain non-executive employees when they join our Company in anticipation of contributions that will create value in the Company. We would expect any such grant to be
subject to a lapsing repurchase right by the Company over a period of time, but in certain circumstances we may grant fully vested shares. Because the shares would have a defined value at the time the stock grants are made, stock grants are often
perceived as having more immediate value than stock options, which have a less calculable value when granted. However, we would expect generally to grant fewer shares of stock than the number of stock options we would grant for a similar purpose.

Subsequent Equity Incentives

Stock option awards.We may make annual stock option awards as part of our overall annual review process. The Compensation Committee believes that stock options provide management with a strong link to long-term corporate performance
and the creation of stockholder value. We expect that the annual aggregate value of these awards would be set near competitive median levels for companies represented in the compensation data we review. As is the case when the amounts of base salary
and initial equity awards are determined, a review of all components of compensation is conducted when determining equity awards to ensure that total compensation conforms to our overall philosophy and objectives.

In addition, John C. Deighan, our Corporate Controller, was granted an option to purchase 20,000 shares of our common stock at an exercise price of $4.80
per share on March 13, 2007 in recognition of his agreement to assume the additional responsibilities as acting Principal Financial Officer of the Company and the achievement of certain corporate finance reporting goals of the Company in the
latter part of 2006.

We are in the process of evaluating our use of annual stock option awards after executives or other non-executive
employees join our Company and in particular whether such awards provide proper incentives to executives and other non-executives of the Company.

Stock awards. In the recent past, we have only made grants of stock as part of our annual review program to our current President and Chief Executive Officer. However, we may make these grants to executives and certain
non-executive employees as part of the annual review process in anticipation of contributions that will create value in the Company. See Initial stock awards above for a discussion of the expected terms of, reasons for granting and
expected amount of grants of stock.

Pursuant to the terms of our employment agreement with our President and Chief Executive Officer, we
were obligated to issue our President and Chief Executive Officer 100,000 shares of our common stock upon satisfaction of certain goals that were to be agreed upon between us and Mr. Bologna. Pursuant to an amendment to his employment agreement
dated December 8, 2006, the Board of Directors granted Mr. Bologna these fully-vested shares in recognition of the fact that Mr. Bolognas performance through the date of such amendment had exceeded any goals the Board of
Directors would have established for Mr. Bolognas initial performance.

Signing Bonus

In certain circumstances, we utilize cash signing bonuses when executives join us. When used, such cash signing bonuses are repayable in full to the
Company if the employee recipient voluntarily terminates employment with us prior to the first anniversary of the date of hire. Whether a signing bonus is paid, and the amount thereof, is determined on a case-by case basis based on the specific
circumstances surrounding the hiring of a new executive. For example, we will consider paying a signing bonus to compensate for amounts forfeited by an executive upon terminating prior employment, and/or to create additional incentive for an
executive to join our Company in a position where there is high market demand. In 2006, we paid our President and Chief Executive Officer a cash signing bonus of $100,000. The amount of the signing bonus was determined in arms-length negotiations
between Mr. Bologna and our Board of Directors, taking into account his extensive experience, track record and the Companys request that he relocate to the Princeton, New Jersey area.

Non-Qualified Deferred Compensation

We have established an Executive Deferred Compensation Plan, which became effective on May 5, 1999. It was established primarily for the purpose of attracting and retaining qualified executive talent and to provide them with an
important component of a competitive and attractive executive benefit program. Participants in the plan are permitted in their sole discretion to defer receipt of, and income taxation on, up to 50% of their regular base salary and all or any portion
of any bonus until they terminate their

##### Table of Contents

employment with us. Our Executive Deferred Compensation Plan is discussed in further detail under the heading Non-Qualified Deferred Compensation
Plan on page 16 of this Amendment No. 1 to the Annual Report on Form 10-K/A. Our President and Chief Executive Officer has not elected to defer any portion of his salary or any bonus he may receive under this plan. However, we contribute
an amount equal to 5% of our President and Chief Executive Officers annual base salary to this plan for his benefit. While our President and Chief Executive Officer currently participates in this plan, we do not anticipate offering the
opportunity to participate in this plan to any employees who may join us in the future.

Perquisites and Other Personal Benefits

We provide named executive officers with perquisites and other personal benefits that we and the Compensation Committee believe are
reasonable and consistent with our overall compensation program to better enable the Company to attract and retain superior employees for key positions. The Compensation Committee periodically reviews the levels of perquisites and other personal
benefits provided to executive officers.

We maintain broad-based benefits and perquisites that are offered to all employees,
including health insurance, life and disability insurance, dental insurance and a 401(k) plan, including Company matching contributions. We also provide relocation expense reimbursement under certain circumstances. In addition to these
broad-based benefits and perquisites, we provide all employees, other than our President and Chief Executive Officer, with life insurance in an amount equal to three times their current salary.

In connection with our President and Chief Executive Officer joining our Company in 2006, we agreed to provide him $2,000,000 of life insurance for a
beneficiary designated by him, reimbursement of expenses in connection with his relocation to the Princeton, New Jersey area (including costs associated with the sale of his existing residence, purchase of a new residence and obtaining temporary
living quarters), legal costs associated with negotiating his employment arrangement and tax gross-ups to offset the tax effects of such payments to him under his employment arrangement with us. For more details about these payments, see the
discussion relating to Mr. Bolognas employment agreement with us beginning on page 13 of this Amendment No. 1 to the Annual Report on Form 10-K/A. The extent and amount of these benefits were determined in arms-length negotiations
between the President and Chief Executive Officer and our Board of Directors, taking into account his extensive experience, track record and the Companys request that he relocate to the Princeton, New Jersey area. In addition, attributed costs
of the personal benefits and perquisites received by our President and Chief Executive Officer and our other named executive officers in 2006, are included in the Summary Compensation Table on page 10 of this Amendment No. 1 to the
Annual Report on Form 10-K/A.

Termination Based Compensation

Severance. Upon termination of employment, most executive officers are entitled to receive severance payments under their employment
agreements or offer letters. In determining whether to approve and as part of the process of setting the terms of such severance arrangements, the Compensation Committee recognizes that executives and officers often face challenges securing new
employment following termination. Our President and Chief Executive Officers employment agreement provides, if his employment is terminated without cause, for (a) the payment by the Company of severance consisting of (i) a lump sum
payment in an amount equal to two times the Chief Executive Officers most recent base salary, (ii) an amount equal to two times the average of the last four annual bonuses paid to the Chief Executive Officer or two times the amount of the
largest bonus paid to the Chief Executive Officer within the last three years, whichever is greater and (iii) an amount equal to the Chief Executive Officers annual bonus target pro-rated by the number of days worked by the Chief
Executive Officer in the last calendar year of his employment, and (b) the continuation by the Company of medical and dental insurance coverage for the Chief Executive Officer and the Chief Executive Officers family until the later of
(i) thirty-six months following the effective date of such termination or (ii) the date which would have been the end of the current term of his employment agreement but for such termination. For more detail about the provisions of
Mr. Bolognas severance arrangements with us, see the discussion under Thomas A. Bologna, President and Chief Executive Officer beginning on page 18 of this Amendment No. 1 to the Annual Report on Form 10-K/A. We believe
that our President and Chief Executive Officers severance package is generally in line with severance packages offered to chief executive officers of companies of similar size to us represented in the compensation data we reviewed.

Acceleration of vesting of equity-based awards. In general, the equity awards under our 2005 Amended and Restated Stock Plan are subject
to acceleration in certain circumstances at the discretion of the administrator of the 2005 Amended and Restated Stock Plan. See the discussion under the heading Our 2005 Amended and Restated Stock Plan beginning on page 17 of this
Amendment No. 1 to Annual Report on Form 10-K/A.

Tax and Accounting Implications

Deductibility of Executive Compensation

As part of its role, the Compensation Committee reviews and considers the deductibility of executive compensation under Section 162(m) of the Internal Revenue Code, which provides that we may not deduct compensation of more than
$1,000,000 that is paid to certain individuals. We believe that compensation paid under the management incentive plans are generally fully deductible for federal income tax purposes. We believe that the options granted under our 2005 Amended and
Restated Stock Plan qualify as performance-based compensation.

Non-Qualified Deferred Compensation

On October 22, 2004, the American Jobs Creation Act of 2004 was signed into law, changing the tax rules applicable to non-qualified deferred
compensation arrangements. While the final regulations have not become effective yet, we believe we are operating in good faith compliance with the statutory provisions which were effective January 1, 2005. A more detailed discussion of our
Executive Deferred Compensation Plan is provided on page 16 of this Amendment No. 1 to the Annual Report on Form 10-K/A under the heading Non-Qualified Deferred Compensation Plan.

Accounting for Stock-Based Compensation

Beginning on January 1, 2006, we began accounting for stock-based payments, including awards under our 2005 Amended and Restated Stock Plan, in accordance with the requirements of Statement of Financial Accounting Standards
No. 123 (revised 2004), Share-Based Payment,or SFAS 123(R)

Compensation Committee Report

The Compensation Committee of the Board of Directors of the Company has reviewed and discussed the Compensation Discussion and Analysis required by
Item 402(b) of Regulation S-K with management and, based on such review and discussions, the Compensation Committee recommended to the Board of Directors of the Company that the Compensation Discussion and Analysis be included in this Amendment
No. 1 to the Annual Report on Form 10-K/A.

Discussion of Summary Compensation Table and Grants of Plan-Based Awards

The terms of
Mr. Bolognas compensation are derived from our employment agreement with him and the annual performance review by our Compensation Committee. The terms of Mr. Bolognas employment agreement with us were the result of extensive
negotiations between us and Mr. Bologna and were approved by our Board of Directors. The terms of Mr. Deighans and Mr. Browns compensation are derived from our offer letters. Annual salary increases, annual equity awards
and cash bonuses, if any, for Mr. Bologna are determined by the Board of Directors. The terms of Dr. Kellys severance arrangement with us were the result of negotiations between us and Dr. Kelly at the time of his termination
and were approved by our Board of Directors.

All of the equity awards disclosed in the Grants of Plan-Based Awards table were issued under
our 2005 Amended and Restated Stock Plan. All option awards were granted with an exercise price per share equal to the closing price of our common stock on the NASDAQ Global Market on the day prior to the grant date of each award. Subject to the
terms and conditions of the 2005 Amended and Restated Stock Plan and the option agreements issued in connection with these grants, all of the options granted in 2006 vest monthly in forty-eight equal tranches over four years, other than the options
granted to Dr. Poste which were granted in connection with his service as a director and which vest monthly in thirty-six equal tranches over three years.

Pension Benefits

We do not have any qualified or non-qualified defined benefit pans.

Non-Qualified Deferred Compensation Plan

Pursuant to
our Executive Deferred Compensation Plan, certain executives may defer the payment of certain cash compensation that they may earn of up to 50% of such persons regular base salary. Deferral elections are made by eligible executives each year
for amounts to be earned in the following year. Additionally, eligible executives may elect to defer all or a portion of bonuses no earlier than one month prior to the beginning of the year for which the bonus will be earned. Eligible executives may
also elect to defer all or a portion of other cash incentive compensation no later than six months before the end of the year or other period for which the cash incentive compensation will be earned.

Benefits under our Executive Deferred Compensation Plan will typically be paid six months after termination. However, upon a showing of financial
hardship and approval of the Compensation Committee, an executive may be allowed to access funds in their deferred compensation account earlier than the time specified. Benefits can be received either as a lump sum payment or in annual installments
as designated by the executive. The executive has a choice of investment vehicles in which to invest amounts contributed to the Executive Deferred Compensation Plan and earnings or losses on account balances are based on the performance of the
chosen investment vehicles.

The following tables provides information with respect to the contributions, earnings, withdrawals and
balances under our Executive Deferred Compensation Plan during the fiscal year ended December 31, 2006 for each of the individuals named in the Summary Compensation Table.

Potential Payments upon Termination or Change of Control

Generally, regardless of the manner in which a named executive officers employment terminates, he is entitled to receive amounts
earned during his term of employment. Such amounts include:



| |  |  | the portion of the executives base salary that has accrued prior to any termination and not yet been paid;
| | - |  | -----------------------------------------------------------------------------------------------------------



| |  |  | unused vacation pay;
| | - |  | --------------------



| |  |  | distribution under the executives 401K plan (assuming the executive participated in the plan); and
| | - |  | ---------------------------------------------------------------------------------------------------



| |  |  | amounts contributed by the executive and us under our Executive Deferred Compensation Plan (assuming the executive participated in the plan).
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------

In addition, we have entered into certain agreements and maintain certain plans that may require us to make additional payments and/or
provide additional benefits to the individuals named in the Summary Compensation Table in the event of a termination of employment or a change of control.

Our 2005 Amended and Restated Stock Plan

Under our 2005 Amended and Restated Stock Plan, if
we are to be consolidated with or acquired by another entity in a merger, sale of all or substantially all of our assets or otherwise, the administrator of our 2005 Amended and Restated Stock Plan or the board of directors of any entity assuming our
obligations under the 2005 Amended and Restated Stock Plan shall, as to outstanding options, either (i) make appropriate provision for the continuation of such options by substituting on an equitable basis for the shares then subject to such
options either the consideration payable with respect to the outstanding shares of our common stock in connection with the transaction or securities of any successor or acquiring entity, (ii) upon written notice to the participants, provide
that all options must be exercised (either (a) to the extent then exercisable or (b) at the discretion of the administrator of the 2005 Amended and Restated Stock Plan, all options being made fully exercisable) within a specified number of
days of the date of such notice, at the end of which period the options shall terminate or (iii) terminate all options in exchange for a cash payment equal to the excess of the fair market value of the shares subject to such options as
determined in accordance with the 2005 Amended and Restated Stock Plan (either (a) to the extent then exercisable or (b) at the discretion of the administrator of the 2005 Amended and Restated Stock Plan, all options being made fully
exercisable) over the exercise price thereof.

With respect to outstanding stock grants, the administrator of the 2005 Amended and Restated Stock Plan
or the successor board, shall either (i) make appropriate provisions for the continuation of such stock grants by substituting on an equitable basis for the shares then subject to such stock grants either the consideration payable with respect
to the outstanding shares of our common stock in connection with the transaction or securities of any successor or acquiring entity, (ii) upon written notice to the participants, provide that all stock grants must be accepted (to the extent
then subject to acceptance) within a specified number of days of the date of such notice, at the end of which period the offer of the stock grants shall terminate or (iii) terminate all stock grants in exchange for a cash payment equal to the
excess of the fair market value of the shares subject to such stock grants over the purchase price thereof, if any. In addition, in the event of such a transaction, the administrator of the 2005 Amended and Restated Stock Plan may waive any or all
of our repurchase rights with respect to outstanding stock grants.

Our Executive Deferred Compensation Plan

Benefits under our Executive Deferred Compensation Plan are typically paid six months after termination in order to comply with Section 409A of the
Internal Revenue Code. Benefits can be received either as a lump sum payment or in annual installments as designated by the executive.

Thomas A. Bologna, President and Chief Executive Officer

Pursuant to our employment agreement with Mr. Bologna,
in the event of a change of control, all stock options held by Mr. Bologna which have not previously vested shall immediately and fully vest and shall remain exercisable for their full term. If Mr. Bolognas employment is terminated
by us without cause or by Mr. Bologna for good reason, then immediately upon the date of Mr. Bolognas termination, to the extent that any of Mr. Bolognas stock options have not vested in full, an additional number of
Mr. Bolognas stock options will vest such that Mr. Bologna will be vested in such number of stock options calculated as if Mr. Bologna remained employed with us for an additional 24 months following the date of termination, and
the vested options shall remain exercisable for their full term. If Mr. Bolognas employment is terminated as a result of his death or disability, then immediately upon the date of Mr. Bolognas termination, all stock options
held by Mr. Bologna shall immediately and fully vest and shall remain exercisable for their full term.

If Mr. Bolognas
employment under his employment agreement is terminated by us for cause or by Mr. Bologna in the absence of a good reason, or the term of the employment agreement expires, we will pay to Mr. Bologna his accrued but unpaid salary, his
accrued unused vacation and his unreimbursed expenses. If Mr. Bolognas employment under the employment agreement is terminated either by us without cause or by Mr. Bologna for good reason, or because of Mr. Bolognas death
or disability, then (i) we will pay to Mr. Bologna his accrued but unpaid salary, his accrued unused vacation and his unreimbursed expenses, (ii) we will pay Mr. Bologna a lump sum payment equal to (A) an amount equal to two
times his most recent base salary plus (B) an amount equal to two times the average of the last four annual bonuses paid to him, or two times the amount of the largest bonus paid to him within the last three years, whichever is greater,
(iii) we will pay Mr. Bologna an amount equal to his annual bonus target prorated by the number of days worked by him in the last calendar year of his employment and (iv) in certain circumstances we will continue to provide medical
and dental insurance coverage for him and his family until the later of (A) 36 months following the effective date of his termination or (B) the date which would have been the end of the current term of the employment agreement but for the
earlier termination thereof.

Under the employment agreement, cause means that Mr. Bologna has (i) intentionally
committed an act or omission that materially harms us, (ii) been grossly negligent in performance of his duties to us, (iii) committed an act of moral turpitude, (iv) committed an act of fraud or material dishonesty in discharging his
duties to us, (v) breached any material provision of the employment agreement or any nondisclosure or non-competition agreement between us and Mr. Bologna that results in material harm to us, or (vi) breached any material provision of
any code of conduct or ethics policy in effect at our Company that results in material harm to us; provided, that in the case of subparagraph (ii) where such gross negligence and the effects of such gross negligence are capable of remedy by
Mr. Bologna, there shall be no cause unless we provide Mr. Bologna with written notice reasonably detailing the purported basis for the cause and Mr. Bologna fails to remedy within 30 days after his receipt of such notice.

Under the employment agreement, good reason means the occurrence of one or more of the following without
Mr. Bolognas express written consent: (i) a substantial diminution in his title, duties, responsibilities or authority with us, (ii) a reduction in his salary or bonus target, (iii) our failure to timely pay or provide him
with any salary, bonuses, benefits or other compensation due to

him under the employment agreement, (iv) our dissolution or liquidation or our filing of a bankruptcy petition, (v) relocation of our headquarters
to a location outside of the Princeton, New Jersey area, (vi) Mr. Bologna not being elected as a member of our Board of Directors or (vii) a change of control as used in the employment agreement; provided, that in the case of subparagraphs
(i), (ii) or (iii) there shall be no good reason unless Mr. Bologna provides our Board of Directors with written notice reasonably detailing the purported basis for the good reason and we fail to remedy within 30 days after its
receipt of such notice.

Under the employment agreement, a change of control shall occur on the date that either of the
following occurs: (i) any Person (as such term is used in Sections 13(d) and 14(d) of the Securities Exchange Act of 1934, as amended) becomes the Beneficial Owner (as defined in Rule 13d-3 under said Act), directly or
indirectly, of our securities representing more than 50% of the total voting power represented by our then outstanding voting securities (excluding for this purpose our Company or its affiliated entities or any of our executive benefit plans)
or (ii) a merger or consolidation of our Company whether or not approved by our Board of Directors, other than a merger or consolidation which would result in our voting securities outstanding immediately prior thereto continuing to represent
(either by remaining outstanding or by being converted into voting securities of the surviving entity or the parent of such corporation) at least 50% of the total voting power represented by our voting securities or such surviving
entity or parent of such corporation outstanding immediately after such merger or consolidation, or the consummation of an agreement for the sale or disposition of all or substantially all of our assets.

The following table summarizes the potential payments to Mr. Bologna assuming his employment with us is terminated or a change of control occurs on
December 31, 2006, the last day of our fiscal year.

Members of our Board of Directors and committee members also receive stock option grants both upon
joining the Board of Directors and on an annual basis in line with recommendations by the Compensation Committee, which grants are non-qualified stock options under our 2005 Amended and Restated Stock Plan, and which typically vest in monthly
increments over three years. In addition, we reimburse each member of our Board of Directors who is not an employee for reasonable travel and other expenses in connection with attending meetings of the Board of Directors.

Consulting Agreement with L.E.K. Consulting LLP

On November 24, 2005, we entered into a consulting agreement with L.E.K. Consulting LLP, of which Dr. Noonan is a partner. Under the terms of the agreement, we paid L.E.K. fees and expenses of $353,050
during fiscal year 2006 in connection with their market analysis and strategic planning services, which were completed early in 2006.

Employee Benefit
Plans

Corporate 401(k) Plan

We sponsor a 401(k) plan covering employees who meet certain defined requirements. Under the terms of our 401(k) plan, participants may elect to make contributions on a pre-tax and after-tax basis, subject to certain
limitations under the Internal Revenue Code and we may match a percentage of employee contributions, on a discretionary basis, as determined by our Board of Directors. We currently match 50% of the first 4% of employee contributions. We may make
other discretionary contributions to the 401(k) plan pursuant to a determination by our Board of Directors.

Compensation Committee Interlocks and
Insider Participation

Our Compensation Committee has two members, Dr. Hecht (Chairman) and Ms. Williams. None of our
executive officers serve as a member of the board of directors or compensation committee of any other entity that has one or more executive officers serving as a member of our Board of Directors or our Compensation Committee.



|Item 12. | SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT AND RELATED STOCKHOLDER MATTERS
|-------- | ----------------------------------------------------------------------------------------------

Security Ownership of Directors and Executive Officers

The following table sets forth the beneficial
ownership of our common stock as of March 15, 2007, except as noted, for (a) each stockholder known by us to own beneficially more than 5% of our common stock; (b) each of our Directors; (c) each executive officer named in the
Summary Compensation Table; (d) and all of our current Directors and executive officers as a group. Beneficial ownership is determined in accordance with the rules of the Securities and Exchange Commission and includes voting or investment
power with respect to the securities. We deem shares of common stock that may be acquired by an individual or group within the 60-day period following March 15, 2007 pursuant to the exercise of options or warrants to be outstanding for the
purpose of computing the percentage ownership of such individual or group, but such shares are not deemed to be outstanding for the purpose of computing the percentage ownership of any other person shown in the table. Percentage of ownership is
based on 29,349,773 shares of common stock outstanding on March 15, 2007. Except as indicated in footnotes to this table, we believe that the stockholders named in this table have sole voting and investment power with respect to all shares of
common stock shown to be beneficially owned by them based on information provided to us by these stockholders. Unless otherwise indicated, the address for each director and current executive officer is c/o Orchid Cellmark Inc., 4390 U.S. Route One,
Princeton, New Jersey 08540.
