##### 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 Amendment No. 1 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 eTag assays 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 HIV drugs such as CCR5 inhibitors, 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. These factors and others are more fully described in Risk Factors and elsewhere in our Report, as amended. We assume no obligation to update any forward-looking statements.

requires our directors and executive officers, and persons who own more than ten percent of a registered class of our equity securities, to file with the SEC initial reports of ownership and reports of changes in ownership of our common stock and
other equity securities. Officers, directors and greater than ten percent stockholders are required by SEC regulation to furnish us with copies of all Section 16(a) forms they file.

To our knowledge, based solely on a review of copies of such reports furnished to us and written representations that no other reports were required,
during the fiscal year ended December 31, 2006, all Section 16(a) filing requirements applicable to our officers, directors and greater than ten percent beneficial owners were complied with.

CODE OF ETHICS

We have adopted a Code of Business Conduct and Ethics that applies to our directors and employees (including our principal executive officer, principal financial officer, principal accounting officer and controller), and have posted the
text of the policy on our website (www.monogrambio.com) in connection with Investor materials; however, information found on our website is not incorporated by reference into this report. In addition, we intend to promptly disclose
(i) the nature of any amendment to the policy that applies to our principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions and (ii) the nature of any
waiver, including an implicit waiver, from a provision of the policy that is granted to one of these specified individuals, the name of such person who is granted the waiver and the date of the waiver on our website in the future.

AUDIT COMMITTEE

The
Audit Committee of the Board of Directors oversees our corporate accounting and financial reporting process. For this purpose, the Audit Committee performs several functions. Three directors comprise the Audit Committee: Cristina H. Kepner (Chair),
William Jenkins and Edmon R. Jennings. The Board of Directors annually reviews the Nasdaq listing standards definition of independence for Audit Committee members and has determined that all members of the Companys Audit Committee are
independent (as independence is currently defined in Rule 4350(d)(2)(A)(i) and (ii) of the Nasdaq listing standards). The Board of Directors has determined that Cristina H. Kepner qualifies as an audit committee financial expert, as
defined in applicable SEC rules.

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 and benefits and, for 2007, include 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 meet 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.

##### Table of Contents

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 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.

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 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 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 2005, 2006 and 2007, these awards were granted at the first regularly scheduled board meeting of the calendar year, on March 2,
2005, April 7, 2006 and March 29, 2007, respectively.

Elements Used to Achieve Compensation Objectives

Base Salary In determining base salaries for our executive officers, we benchmark
each of our executive positions using the Radford Global Life Sciences Survey for companies nationwide with 150-499 employees. We use the 50thpercentile as a general benchmark for salary levels. However, many factors affect 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. At the beginning of 2006, we concluded that, because of the then potential impact of the contingent value rights on our cash position, it would be prudent to not implement a cash
bonus plan for 2006. Accordingly, no bonus plan was implemented and no payments were made to our executive officers for 2006. However, for 2007, we have implemented a cash bonus plan that provides for the payment of cash bonuses based on the
compensation committees assessment of our performance against specified revenue targets and other corporate goals for the year, as well as an assessment of individual performance for each executive. The chief executive officer is eligible for
a total target bonus of up to 40% of base salary. The other executive officers are 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 50thpercentile as a general
target for potential bonus levels.

Equity Incentive We utilize 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. We determine 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.

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, effective January 2007. 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. 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 salary payments and continuation of certain healthcare
benefits for twelve months and full vesting of his outstanding stock options. None of our other executive officers have agreements providing for any severance payments, except as described below under Change in Control.

Change in Control In the event of an actual or constructive termination of employment, other than for cause, within
twelve months after a change of control of the company, our chief executive officer will receive the following termination benefits: continuation of salary and certain healthcare benefits for a period of twelve months and full vesting of outstanding
stock options. 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 other named executive officers will receive, in
a lump sum payment, one years salary and full vesting of outstanding stock options.

Compensation of the Named Executive Officers in 2006

William D. Young, Chairman and Chief Executive Officer Mr. Youngs base salary was set at $455,000 for 2006,
reflecting the compensation committees assessment of his performance in leading the company and based on his experience, skills and leadership abilities. As a result of an assessment of the companys cash position at the start of 2006, we
did not implement a cash bonus plan for 2006 and no cash bonus was paid to Mr. Young for the year. At the time of our annual review of stock option grants, on April 7, 2006, Mr. Young was granted an option to purchase 300,000 shares
of common stock at an exercise price of $1.62 per share. This

##### Table of Contents

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 and Chief Scientific Officer; Kathy Hibbs, Senior Vice President and General Counsel Base salary for the other named executive officers were set for 2006 at the following levels:
Mr. Merriweather$260,000; Mr. Welch$283,000; Mr. Petropoulos$273,000; and Ms. Hibbs$260,000. These salary levels reflect the compensation committees concurrence with Mr. Youngs assessment
of their performance in leading their functions and in contributing to the companys overall progress. As a result of an assessment of the companys cash position at the start of 2006, we did not implement a cash bonus plan for 2006 and no
cash bonuses were paid to these executive officers for the year. At the time of our annual review of stock option grants, on April 7, 2006, the named executives were granted options to purchase the following number of shares of common stock at
an exercise price of $1.62 per share: Mr. Merriweather100,000; Mr. Welch175,000; Mr. Petropoulos100,000; and Ms. Hibbs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 and his relocation to the San Francisco Bay Area, we paid him mortgage assistance payments in 2006 of $60,000 and reimbursed relocation costs of $6,550.

EMPLOYMENT, SEVERANCE AND CHANGE OF CONTROL AGREEMENTS

William D. Young

We have an
agreement with William D. Young governing his employment as our Chief Executive Officer. This employment agreement provides for an initial base salary of $300,000 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, plus a yearly special bonus of between $50,000 and $100,000, grossed up for tax purposes. In addition, the agreement contains a non-solicitation agreement.
Mr. Young recommended that his salary be reduced as part of the November 2002 business restructuring. The Compensation Committee of the Board of Directors determined, and Mr. Young agreed, that Mr. Youngs base salary would be
reduced by $50,000 to $280,000 beginning in November 2002 and that no bonuses would be paid for services performed by Mr. Young during 2002 or 2003 pursuant to this agreement. In addition, Mr. Young has waived the bonus described in the
Employment Agreement for years after 2003.

As required by the agreement, prior to the commencement of Mr. Youngs employment, we
also granted him a stock bonus award of 150,000 fully vested shares of the common stock, in consideration of his past service as our Chairman of the Board prior to becoming our Chief Executive Officer. The agreement also provides for the following:



| |  |  | a cash bonus in the gross amount of $180,000, granted on January 15, 2000, and an additional cash bonus in the gross amount of $180,000, granted on
April 15, 2000;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | an incentive stock option under our 2000 Equity Incentive Plan covering 150,000 shares of the common stock, which is now fully vested;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------



| |  |  | a non-statutory stock option, granted outside of our 2000 Equity Incentive Plan, covering 250,000 shares of the common stock, which is now fully vested; and
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | a non-statutory stock option, granted outside of our 2000 Equity Incentive Plan, covering 250,000 shares of the common stock, which is now fully vested.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------

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, or his estate, his
base salary, at the level in effect at the time of termination, for an additional 12 months.

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. 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.

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, 2006 and that all eligibility requirements under the executive severance benefits agreements or applicable
employment agreement were met.

Note:



|(a) | Represents retainer, committee and meeting fees.
|--- | ------------------------------------------------

|(b) | Represents the compensation expense related to all outstanding options that we recognized for the year ended December 31, 2006 under Statement of Financial Accounting Standards
No. 123R (SFAS123R), adjusted to exclude estimates of forfeitures. This expense is determined by computing the fair value of each option on the grant date in accordance with SFAS 123R and recognizing that amount as expense ratably over the
option vesting term and accordingly includes the portion of 2005 and 2006 options granted in previous years, that vested in 2006. The grant date fair value of options granted to directors in 2006 and 2005 was $23,576 and $32,960, respectively, for
each director.
|--- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Each of our non-employee directors received an annual retainer of $15,000 in 2006, paid in equal quarterly
installments. In addition, in 2006 each non-employee director received a fee of $1,500 for each Board of Directors meeting attended in person ($2,500 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 the fiscal year ended December 31, 2006, the total cash compensation paid to non-employee directors was $146,500. 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. In 2007, the Board of Directors increased the cash compensation payable to our non-employee directors. In 2007, each
of the non-employee directors shall receive an annual retainer of $20,000, paid in equal quarterly installments, a fee of $2,000 for each Board of Directors meeting attended in person, 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.

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, 2006, 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, 2006, 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.

|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
March 1, 2007 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 and warrants if he or she possesses sole or shared voting or investment power of that security, and includes options and
warrants that are currently exercisable or exercisable within 60 days of March 1, 2007. 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 131,742,340 shares of common stock outstanding as of
March 1, 2007. Options and warrants to purchase shares of the common stock that are exercisable within 60 days of March 1, 2007, are deemed to be beneficially owned by the persons holding these options and warrants 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.

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.



|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 6 directors are independent directors within the meaning of the applicable NASDAQlisting standards: Thomas Baruch, 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.

Merger with ACLARA BioSciences, Inc.

In connection with our December 2004 merger with ACLARA, we issued approximately 61.9 million shares of our common stock and approximately 61.9 million contingent value rights, or CVRs, to ACLARA
stockholders. Thomas R. Baruch and John Mendlein, members of our Board of Directors, were directors of ACLARA prior to the merger. Alfred G. Merriweather and Michael J. Dunn were executive officers of ACLARA prior to the merger. In connection with
the merger, each share of ACLARA common stock held by each of these former ACLARA directors and officers was exchanged for 1.7 shares of our common stock and 1.7 CVRs. In addition, options to acquire shares of ACLARA common stock held by these
former ACLARA directors and officers were converted into options to acquire shares of our common stock and CVRs, at the same ratio. In June, 2006, each holder of a CVR became entitled to receive $0.88 per CVR.

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 2005 were $0.59 million, of which $0.39 million was for services provided by Ernst & Young LLP and $0.20 million was for services provided by PricewaterhouseCoopers LLP. 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 managements assessment 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 and 2005.

TAX FEES

There were no fees for tax related services in 2006 and 2005 paid to PricewaterhouseCoopers LLP or Ernst & Young LLP.

ALL OTHER FEES

There were no fees for other services not included above in 2006 and 2005.

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 and Ernst & Young LLP, as applicable, is compatible with maintaining the independent registered public accounting firms independence.
