##### Table of Contents

This Amendment No. 1 contains certain forward-looking statements within the meaning of the safe
harbor provisions of the Private Securities Litigation Reform Act of 1995 including, without limitation, statements regarding development and commercialization of our proposed products and services, and the possible growth of our business into
new markets. These statements, which sometimes include words such as expect, goal, may, anticipate, should, continue, or will, reflect our expectations and
assumptions as of the date of this Annual Report based on currently available operating, financial and competitive information. Actual results could differ materially from those in the forward-looking statements as a result of a number of factors,
including our ability to successfully complete the development and clinical validation of HERmark and other assays based on the VeraTag technology platform and commercialize these assays for guiding treatment of cancer patients, the potential role
of our assays in the development and use of new classes of human immunodeficiency virus, or HIV, drugs such as CCR5 inhibitors including Pfizers Selzentry, the market acceptance of our products, the effectiveness of competitive products,
new products and technological approaches, the risks associated with our dependence on patents and proprietary rights, the possible infringement of the intellectual property rights of others, and our ability to raise additional capital if needed.
These factors and others are more fully described in Risk Factors and elsewhere in this Form 10-K. We assume no obligation to update any forward-looking statements.

COMPENSATION
DISCUSSION AND ANALYSIS

Overview

The goal of our
executive compensation program is to provide a structure of incentives and rewards that will drive behavior and performance in a way that builds long term value for our stockholders. In support of this goal we have implemented compensation and
benefit programs that are designed to:



| |  |  | drive and reward performance
| | - |  | ----------------------------



| |  |  | align the interests of management and stockholders
| | - |  | --------------------------------------------------



| |  |  | enable the recruitment and retention of high quality executives
| | - |  | ---------------------------------------------------------------



| |  |  | provide fair and reasonable levels of compensation
| | - |  | --------------------------------------------------

We have implemented specific compensation elements to address these objectives. These have included base salary, equity participation, benefits and a cash bonus plan. Some of these are short term in nature and others are more relevant as
longer term incentives and rewards. Our goal is to have a blend of compensation elements that in the aggregate meets the objectives described above.

The
compensation committee of our board of directors oversees our executive compensation arrangements, in accordance with a committee charter approved by the board of directors.

The programs described here relate to all of our executive officers, including the vice presidents and senior vice presidents who report directly to our chief executive officer, and to the chief executive officer
himself. This includes those individuals who are identified as named executive officers.

Compensation Objectives

The following are the principal objectives of our compensation programs.

Performance  We strive to maintain a performance-oriented culture. Each of our compensation elements are designed to recognize the actual performance and the potential future performance of our executive
officers. We expect all of our executive officers to perform to high standards of competence. We also expect them to set and achieve appropriate goals for their area of responsibility and for the company as a whole.

Alignment with stockholders  We seek to align ourselves with the interests of our stockholders. We do this by setting our goals based on the
business milestones that we believe are most likely to drive long term stockholder value and by tying significant elements of executive compensation to our business success. Cash bonuses are designed to acknowledge short term goal accomplishment
while over the long term, executive officers expect to benefit directly from increases in the value of our common stock through equity participation, primarily stock options.

Recruiting and Retention  Building an outstanding organization and delivering excellence in all aspects of our performance requires that we
hire, and retain, high quality executives. We believe that an environment in which employees are able to have an enjoyable, challenging and rewarding work experience is critical to our ability to recruit and retain the right people. A critical
aspect of that environment is the structure of incentives and rewards that are embedded in the compensation structure. We strive to keep this structure competitive so that qualified people are motivated to join our team and to stay at Monogram for
long and successful careers.

Fair and Reasonable  We strive to make our compensation programs fair in two ways. First, we aim
for fairness internally in relation to other executives and to other employees throughout the organization. Second, we seek fairness externally in relation to comparable positions in other companies. We also set compensation levels that are
reasonable in terms of our overall financial and competitive condition as a company and that reflect the experience, skills and level of responsibility of the executive. We utilize data from the Radford Global Life Sciences Survey for companies
nationwide with 150-499 employees to aid in benchmarking our cash compensation levels to outside market conditions. We did not, for 2007, benchmark against a list of specifically identified peer companies, nor do we know which specific
companies data comprises the Radford Global Life Sciences Survey results.

Implementing our Objectives

Roles of the Compensation Committee and Management  The compensation committee of the board of directors operates under a board-approved
charter. This charter specifies the principal responsibilities of the committee as follows: (i) to review and approve



7

##### Table of Contents

the overall compensation strategy (including performance goals, compensation plans, programs and policies, employment and similar agreements with executive
officers); (ii) to determine the compensation and terms of employment of the chief executive officer and the other executive officers; (iii) to administer and to recommend adoption, change or termination of plans, including option plans,
bonus plans, deferred compensation plans, pension plans and (iv) to establish appropriate insurance for the directors and officers. The committee consists of four directors, each of whom satisfies the independence requirements of the Nasdaq
Global Market as well as applicable SEC and IRS regulations.

The chief executive officer and the vice president of human resources attend
compensation committee meetings, except those meetings or portions of those meetings where their respective compensation is being discussed by the committee. The chief executive officer, with the assistance of the vice president of human resources,
presents performance assessments of other executive officers to the compensation committee and proposes ranges of compensation benefits for each officer based upon each respective assessment. Neither the company nor the compensation committee
engaged any third party consultants regarding 2007 executive compensation.

The performance of each of our executive officers is evaluated
annually at the end of the calendar year. The chief executive officers performance is evaluated by the compensation committee and the performance of the other executive officers is evaluated by the chief executive officer and reviewed with the
compensation committee. The factors taken into account in the evaluation of performance include: the extent to which pre-established goals were accomplished and the extent to which the executive demonstrated leadership, creativity, teamwork and
commitment, and embodied our company values. Other factors that are considered in making compensation determinations are the experience, skill level and level of responsibility of the executive and competitive market conditions.

Equity Grant Practices  All options granted to executive officers must be approved by either the compensation committee or the board of
directors. At the time of hire, options are granted effective on the employment start date for the executive. Generally, we assess all of our executive officers on an annual basis for potential additional stock option grants. These annual awards are
approved by the compensation committee or by the board of directors. In 2006, 2007 and 2008, these awards were granted at the first regularly scheduled board meeting of the calendar year, on April 7, 2006, March 29, 2007, and
March 13, 2008, respectively. These options vest in accordance with our normal vesting schedule which is 25% after twelve months and then in equal monthly increments over the remaining three years of a four year vesting term.

Elements Used to Achieve Compensation Objectives

Base Salary  In determining base salaries for our executive officers, we benchmarked
each of our executive positions using the data from the Radford Global Life Sciences Survey for companies nationwide with 150-499 employees. We used the 50th percentile as a general benchmark for salary levels. However, many factors affected the
determination of the salary level for individual executives, including performance, experience, skill, responsibilities and competitive market factors. In general, we seek to provide a fair, reasonable and competitive level of base salary.

Cash Bonus  While we believe that the provision of short-term cash
incentives is important to aligning the interests of executive officers and stockholders, and to the rewarding of performance, we also take into account the overall financial situation of the company. For 2007, we implemented a cash bonus plan that
provided for the payment of cash bonuses based on the compensation committees assessment of our performance against specified pre-determined corporate goals for the year including revenue, operational and product development goals, as well as
an assessment of individual performance for each executive. Payment of bonuses based on these assessments was contingent on a minimum level of revenue being attained. The chief executive officer was eligible for a total target bonus of up to 40% of
base salary. The other executive officers were each eligible for a total target bonus of up to 30% of base salary. In determining these target bonus percentages we benchmarked our executives using the Radford Global Life Sciences Survey for
companies nationwide with 150-499 employees, with the 50thhpercentile as a general target for potential bonus levels. Because the specified minimum
level of revenue was not attained, no cash bonuses were paid to our Named Executive Officers for 2007.

Equity Incentive  We
utilized stock options as the primary method of equity participation for our executive officers. In the future we may consider using other forms of equity participation such as restricted stock grants. Equity incentive awards are determined
separately and independently from cash-based awards. We determined option grants by reference to our own capitalization structure and to internally generated benchmarks that we have established to determine appropriate levels of stock option grants
for our employees. These options vest in accordance with our normal vesting schedule which is 25% after twelve months and then in equal monthly increments over the remaining three years of a four year vesting term.

Benefits  We provide a competitive range of health and other benefit programs to our executive officers. These are provided on the same
basis to executive officers and all employees. These include health and dental insurance, life and disability insurance, and a 401(k) plan under which certain matching contributions are made in company stock.

In addition to these benefit programs, we have implemented a non qualified deferred compensation plan. Those eligible for this plan include members of
the board of directors, the executive officers and certain other senior employees. Under this plan, individuals enrolled in the plan can, by election in advance, defer a portion of their total compensation on a pretax basis. None of our named
executive officers have participated in this plan. There are no special perquisites or benefit programs made available exclusively to any of the executive officers, either individually or as a group.

Relocation  When necessary and appropriate, upon the hire of new executives, we may pay
additional amounts in reimbursement of relocation costs and/or as additional compensation to assist with the high cost of housing in the San Francisco Bay Area.

Severance  Under provisions of our chief executive officers employment agreement, in the event of a termination of employment for reasons other than cause, he is entitled to receive severance
benefits, as described below under Employment, Severance and Change of Control Agreements. We entered into this agreement with Mr. Young to attract and retain his services. None of our other executive officers have agreements
providing for any severance payments, except in the context of a change in control, as described below.

Change in Control
 In the event of an actual or constructive termination of employment, other than for cause, within three months before or twenty-four months after a change of control of the company, our named executive officers will receive severance
benefits, as described below under Employment, Severance and Change of Control Agreements. We enter into these agreements to help attract and retain key executive talent for the company.

Compensation of the Named Executive Officers in 2007

William D. Young, Chairman and Chief Executive Officer  Mr. Youngs base salary was set at $475,000 for 2007, an increase of 4% over his salary for 2006. This increase reflected the compensation committees
assessment of his performance in leading the company and based on his experience, skills and leadership abilities. No cash bonus was paid to Mr. Young for 2007. At the time of our annual review of stock option grants, on March 29, 2007,
Mr. Young was granted an option to purchase 300,000 shares of common stock at an exercise price of $1.88 per share. This option grant was considered appropriate by the compensation committee, taking into account Mr. Youngs
performance, role, responsibilities and anticipated contributions to the company. This option vests in accordance with our normal vesting schedule which is 25% after twelve months and then in equal monthly increments over the remaining three years
of a four year vesting term.

Alfred G. Merriweather, Senior Vice President and Chief Financial Officer; William Welch, Senior Vice
President and Chief Commercial Officer; Christos Petropoulos, Vice President R&D Virology and Chief Scientific Officer; Michael Bates, Vice President Clinical Research Base salary for the other named executive officers were set for
2007 at the following levels, and represented the stated percentage increase over their salaries for 2006: Mr. Merriweather$275,600 (6%); Mr. Welch$297,150 (5%); and Dr. Petropoulos$281,200 (3%). Dr. Bates
base salary for 2007 was initially set at $286,200, representing an 8% increase over his salary for 2006, and then in September 2007 Dr. Bates base salary was further increased to $307,000. These salaries are set at market levels and also
reflect the compensation committees concurrence with Mr. Youngs assessment of their performance in leading their functions, in execution of pre-established goals for their functions and in contributing to the companys overall
progress. Mr. Merriweathers increase in salary was reflected in his promotion to senior vice president. Dr. Bates salary increases in 2007 were higher than other executives in order to bring Dr. Bates salary to a
competitive market level for professionals with his qualifications.

No cash bonuses were paid to any of our Named Executive Officers for
2007. At the time of our annual review of stock option grants, on March 29, 2007, the named executives were granted options to purchase the following number of shares of common stock at an exercise price of $1.88 per share:
Mr. Merriweather100,000; Mr. Welch100,000; Dr. Petropoulos100,000; and Dr. Bates100,000. These option grants were considered appropriate by the compensation committee, taking into account the
executives performance, roles, responsibilities and anticipated contributions to the company. These options vest in accordance with our normal vesting schedule which is 25% after twelve months and then in equal monthly increments over
the remaining three years of a four year vesting term.

In addition, in accordance with our agreement with Mr. Welch at the time of
his recruitment to be our Chief Commercial Officer in 2005 and his relocation to the San Francisco Bay Area, we paid him mortgage assistance payments in 2007 of $40,000.

EMPLOYMENT, SEVERANCE AND CHANGE OF CONTROL AGREEMENTS

William D.
Young

We have an amended and restated agreement with William D. Young governing his employment as our Chief Executive Officer. This
agreement provides for a base salary initially of $475,000 per year, plus a yearly incentive bonus as part of our bonus program based on objectives established by the Board of Directors after consultation with Mr. Young.

Our agreement with Mr. Young specifies that Mr. Youngs employment is at-will. If we terminate his employment for any reason other than
for cause, including in the context of a change of control, however, or if his employment is terminated as a result of death or permanent disability, we have also agreed to continue to pay him his base salary, at the level in effect at the time of
termination, for an additional 12 months. If Mr. Young elects to continue his health insurance under the Consolidated Omnibus Budget Reconciliation Act, or COBRA, following the termination of his employment, then we will pay Mr. Youngs
monthly premium under COBRA until the earliest of (i) twelve months or (ii) the expiration of Mr. Youngs continuation coverage under COBRA. If Mr. Young is constructively terminated within three months prior to or
twenty-four months after a change in control then he will receive a one time cash severance payment equal to twelve months of his base salary plus an amount equal to the bonus that he received for the prior year.

Executive Severance Agreements and Stock Option Acceleration Provisions

We have entered into executive severance benefits agreements with each of our executive officers other than William Young which were amended as of September 20, 2007. These executive severance benefits agreements
provide that if the executive is terminated without cause or constructively terminated within three months prior to or twenty-four months after a change in control then the executive will receive a one time cash severance payment equal to twelve
months of the executives base salary plus an amount equal to the bonus that the executive received for the prior year. If the executive elects to continue his health insurance under COBRA following the termination of his employment, then the
Company shall pay the executives monthly premium under COBRA until the earliest of (i) twelve months or (ii) the expiration of the executives continuation coverage under COBRA.

The stock option agreements we have entered into with our executive officers in connection with stock option grants made to them under the 2004 Plan
provide for acceleration of vesting of the stock option if the executive is terminated without cause or for good reason as of, or within 13 months after, a change in control. Options granted to executives under our 2000 Equity Incentive Plan,
pursuant to the terms of that plan, are also subject to accelerated vesting if the executive is terminated without cause or for good reason as of, or within 13 months after, a change in control.

POTENTIAL PAYOUTS UPON TERMINATION OR CHANGE IN CONTROL

The table below shows the potential payments and benefits to which each Named Executive Officer would be entitled under the executive severance benefits
agreements and stock option acceleration provisions described above and, in the case of Mr. Young, his employment agreement. The amounts shown in the table assume that termination was effective as of December 31, 2007 and that all
eligibility requirements under the executive severance benefits agreements or applicable employment agreement were met.

##### Table of Contents

Each of our non-employee directors received an annual retainer of $20,000 in 2007, paid in equal
quarterly installments. In addition, in 2007 each non-employee director received a fee of $2,000 for each Board of Directors meeting attended in person ($3,000 for directors resident outside of the U.S.), a fee of $500 for each Board of Directors
meeting attended by phone and a fee of $500 for each committee meeting attended by committee members. In addition, the chair of the Audit Committee will receive an annual retainer of $10,000 and the chair of the Compensation Committee will receive
an annual retainer of $5,000. In the fiscal year ended December 31, 2007, the total cash compensation paid to non-employee directors was $207,000. The members of the Board of Directors are also eligible for reimbursement for their expenses
incurred in attending Board meetings in accordance with our policy.

All of our directors are eligible to participate in our 2004 Equity
Incentive Plan, or the 2004 Plan. Option grants to non-employee directors are discretionary. However, the Board of Directors has adopted a policy pursuant to which it makes initial grants of stock options to new non-employee directors at their time
of election to the Board of Directors, and, on an annual basis, grants stock options to its continuing non-employee directors. During the fiscal year ended December 31, 2007, we granted each of our six continuing non-employee directors options
to purchase 20,000 shares of common stock. These options vest monthly over a one-year period; provided that the vesting may accelerate and all shares subject to the options may become immediately exercisable in the event of a change in control of
us.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

During the fiscal year ended December 31, 2007, the following non-employee directors served as members of the Compensation Committee: William Jenkins (Chair), Cristina H. Kepner, John D. Mendlein, and David H.
Persing. During that fiscal year, none of our executive officers served as a member of the board of directors or compensation committee of any entity that has one or more executive officers serving on our Board of Directors or Compensation
Committee.

COMPENSATION COMMITTEE REPORT

The Compensation Committee has reviewed and discussed with management the Compensation Discussion and Analysis (CD&A) contained in this Amendment No. 1 to Annual Report on Form 10-K/A. Based on this review and
discussion, the Compensation Committee has recommended to the Board of directors that the CD&A be included in this Amendment No. 1 to Annual Report on Form 10-K/A for the fiscal year ended December 31, 2007.

|Item 12. | Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters
|-------- | ----------------------------------------------------------------------------------------------

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

The following table sets forth certain information regarding the ownership of our common stock as of April 1, 2008 by: (i) each director and nominee for director; (ii) each of the executive officers named in the Summary
Compensation Table; (iii) all of our executive officers and directors as a group; and (iv) all those known by us to be beneficial owners of more than five percent of our common stock.

Beneficial ownership is determined according to the rules of the Securities and Exchange Commission, and generally means that a person has beneficial
ownership of a security if he or she possesses sole or shared voting or investment power of that security, and includes options, warrants and convertible securities that are currently exercisable or convertible within 60 days of April 1, 2008.
Some of the information with respect to beneficial ownership has been furnished to us by each director, officer or 5% or more stockholder, as the case may be. Except as otherwise indicated, we believe that the beneficial owners of the common stock
listed below, based on the information each of them has given us, have sole investment and voting power with respect to their shares, except where community property laws may apply.

This table lists applicable percentage ownership based on 134,193,374 shares of common stock outstanding as of April 1, 2008. Options and warrants
to purchase shares of the common stock and securities convertible into shares of common stock that are exercisable or convertible within 60 days of April 1, 2008 are deemed to be beneficially owned by the persons holding these securities for
the purpose of computing percentage ownership of that person, but are not treated as outstanding for the purpose of computing any other persons ownership percentage. Shares underlying options, warrants and convertible securities that are
deemed beneficially owned are listed in this table separately in the column labeled Shares Subject to Options, Warrants and Convertible Securities. These shares are included in the number of shares listed in the column labeled
Total Number.

|(1) | Includes securities to be issued under the Companys 2000 Employee Stock Purchase Plan, which contains an automatic annual increase (evergreen) provision equal to
the least of the following amounts: (i) 0.75% of the outstanding shares on the day preceding the first day of the applicable Company fiscal year, (ii) 1,000,000 shares or (iii) an amount as may be determined by the Board, to be added on the first
day of the Company fiscal year.

|(2) | Consists of non-statutory stock options granted to William D. Young outside of the Companys 2000 Equity Incentive Plan pursuant to the terms of an employment agreement between
Mr. Young and the Company described in Item 11 above under Employment, Severance and Change of Control Agreements. The non-statutory stock option grants to Mr. Young were approved by our Board but not by the stockholders.
The employee agreement between Mr. Young and Monogram allowed for a grant of 1,000,000 shares, but only 500,000 shares were granted. The exercise price of the nonstatutory stock options was at 100% of fair market value on the date of grant. All
options are currently fully vested, half of which vested over a four year period and the other half vested over a five year period. The term of the options is ten years or earlier in the event of a termination of continuous service. The options are
set to expire in 2009.

|Item 13. | Certain Relationships and Related Transactions, and Director Independence
|-------- | -------------------------------------------------------------------------

INDEPENDENCE OF THE BOARD OF DIRECTORS

As required under the Nasdaq Stock Market
(Nasdaq) listing standards, a majority of the members of a listed companys Board of Directors must qualify as independent, as affirmatively determined by the Board of Directors. The Board consults with the
Companys counsel to ensure that the Boards determinations are consistent with relevant securities and other laws and regulations regarding the definition of independent, including those set forth in pertinent listing
standards of the Nasdaq, as in effect time to time.

Consistent with these considerations, after review of all relevant transactions or
relationships between each director, or any of his or her family members, and the Company, its senior management and its independent auditors, the Board has affirmatively determined that the following five directors are independent directors within
the meaning of the applicable Nasdaq listing standards: William Jenkins, Edmon Jennings, Cristina Kepner, John Mendlein, and David H. Persing. In making this determination, the Board found that none of these directors or nominees for director had a
material or other disqualifying relationship with the Company. William Young, the Chief Executive Officer of the Company, is not an independent director by virtue of his employment with the Company.

TRANSACTIONS WITH RELATED PERSONS

Indemnity Agreements

We have entered into indemnity agreements with each of our officers and directors which provide, among other things, that we will
indemnify those officers or directors, under the circumstances and to the extent provided for therein, for expenses, damages, judgments, fines and settlements he or she may be required to pay in actions or proceedings which he or she is or may be
made a party by reason of his or her position as a director, officer or other agent of Monogram, and otherwise to the fullest extent permitted under Delaware law and the Companys Bylaws. We also intend to enter into these agreements with our
future directors and officers.

RELATED-PERSON TRANSACTIONS POLICY AND PROCEDURES

It is our practice and policy to comply with all applicable laws, rules and regulations regarding related-person transactions, including the Sarbanes-Oxley Act of 2002 and the Nasdaq listing standards. A
related-person is any executive officer, director, or more than 5% stockholder of the Company, including any of their immediate family members, and any entity owned or controlled by such persons. Under its charter, our Audit Committee is charged
with reviewing and approving all related-person transactions, as required by the Nasdaq rules. In considering related-person transactions, the Audit Committee takes into account the relevant available facts and circumstances. In the event a director
has an interest in the proposed transaction, the director must recuse himself or herself form the deliberations and approval. The Company has not yet adopted a written related-person transactions policy.



|Item 14. | Principal Accounting Fees and Services
|-------- | --------------------------------------

AUDIT FEES

Fees for audit services provided by PricewaterhouseCoopers LLP during 2006 totaled $0.85 million. Fees for audit services
provided in 2007 were $0.84 million. The fees for audit services included fees associated with the annual audit of the financial statements included in our Annual Report on Form 10-K, procedures related to attestation of the effectiveness of
internal control over financial reporting under the requirements of Section 404 of the Sarbanes-Oxley Act of 2002, and the reviews of Monograms quarterly reports on Form 10-Q and other SEC filings.

AUDIT-RELATED FEES

There were no fees for audit-related services in
2006. Fees for audit-related services provided in 2007 were $0.16 million.

TAX FEES

There were
no fees for tax related services in 2006 or 2007 paid to PricewaterhouseCoopers LLP

ALL OTHER FEES

There were no fees for other services not included above in 2006 or 2007.

All fees described above were pre-approved by the Audit Committee.

PRE-APPROVAL POLICIES AND PROCEDURES

The Audit Committee has adopted a policy for the pre-approval of audit, review and attest services, as well as permitted non-audit services to be
performed by our independent registered public accounting firm. The engagement to perform services may be approved on an explicit case-by-case basis before the independent registered public accounting firm is engaged to provide each service or the
engagement may be pre-approved on a collective basis. These services may include audit services, audit-related services, tax services and other services. The Audit Committee has delegated specific pre-approval authority for up to $50,000 to
Ms. Kepner, the Chair of the Audit Committee. These pre-approvals are reported to the Audit Committee at its next scheduled meeting.

The Audit Committee has determined that the rendering of the services other than audit services by PricewaterhouseCoopers LLP is compatible with maintaining the independent registered public accounting firms independence.
