Stock Option Grants



The following table sets forth the stock options we granted during the year ended December 31, 2004 to each of our Named Executive Officers. We have never
granted any stock appreciation rights.



Amounts shown as
potential realizable values are based on compounded annual rates of share price appreciation of five and ten percent over the 10-year term of the options, as mandated by rules of the SEC, and are not indicative of expected share price performance.
Actual gains, if any, on share option exercises are dependent on future performance of the overall market conditions, as well as the option holders continued employment through the vesting period. The amounts reflected in this table may not
necessarily be achieved or may be exceeded. The indicated amounts are net of the option exercise price but before taxes that may be payable upon exercise.

|(6) | Amounts represent hypothetical gains that could be achieved for the respective options if exercised at the end of the option term. The 5% and 10% assumed annual rates of compounded
stock price appreciation are mandated by the rules of the SEC and do not represent an estimate or projection of our future common stock prices. These amounts represent certain assumed rates of appreciation in the value of our common stock from the
fair market value on the date of grant. Actual gains, if any, on stock option exercises are dependent on the future performance of the common stock and overall stock market conditions. The amounts reflected in the table may not necessarily be
achieved.

Year-End Option Table



The following table contains information regarding stock options held by our
named executive officers, and the number of and value of any unexercised in-the-money options, as of December 31, 2004. The value of unexercised in-the-money options at December 31, 2004 is based on a value of $14.17 per share, the fair market value
of our common stock as reflected by the closing price on the Nasdaq National Market on December 31, 2004, less the per share exercise price, multiplied by the number of shares issuable upon exercise of the option.

Employment Agreements



We have entered into employment agreements with some of our Named Executive Officers as described below. In addition to the specific rights set forth in
any agreement, in the event of any change in control, options and restricted stock granted pursuant to the Amended and Restated Stock Incentive Plan contain a change in control provision, which provides for the immediate vesting in full of all
grants or lapse of all restrictions for all grantees.



In April
1999, we entered into an employment agreement with Dr. Bolognesi to serve as our Chief Executive Officer and Chief Scientific Officer. Under this agreement, Dr. Bolognesi is entitled to receive minimum annual compensation of $285,000, an annual
bonus based upon the achievement of certain milestones and all health insurance and other benefits generally made available to our employees. He also received in 1999 a one-time payment of $40,000 for replacement of lost income. In connection with
the agreement, Dr. Bolognesi received a grant of options to purchase 235,000 shares of common stock at $11.625 per share. If Dr. Bolognesis employment is terminated for any reason other than for cause, Dr. Bolognesis employment agreement
provides that he is entitled to his base salary and benefits for two years from the date of termination. In April 2003, Dr. Bolognesis employment agreement was automatically renewed until April 2005, unless terminated earlier in accordance
with its terms. In September 2004, Dr. Bolognesi stopped serving as Chief Executive Officer but continues to serve as Chief Scientific Officer. The Company is currently in negotiations with Dr. Bolognesi with respect to the terms of a new contract.



In March 2000, we entered into an employment agreement with
Dr. Ellis, our former President. Under this agreement, Dr. Ellis is entitled to receive minimum annual compensation of $220,000, an annual bonus based upon the achievement of certain milestones and all health insurance and other benefits generally
made available to our employees. In June 2004, the Company terminated its employment agreement with Dr. Ellis. According to the terms of the Separation and Severance Agreement between Dr. Ellis and the Company, Dr. Ellis is entitled to receive his
monthly base salary as of the date of termination of his employment for a period of two years following termination. The Company will contribute towards medical and dental coverage for Dr. Ellis and his wife through December 2005 as part of the
Separation and Severance Agreement.



In January 2000, we
entered into an employment agreement with Mr. Bonczek, our Chief Financial Officer and General Counsel. Under this agreement, Mr. Bonczek is entitled to receive minimum annual compensation of $210,000 and an annual bonus based upon the achievement
of certain milestones. Pursuant to his agreement, he also received in 2000 a one-time payment of $16,000 for replacement of lost income and in 2001 a one-time payment of $19,790 for reimbursement for moving and miscellaneous expenses. In October
1999, Mr. Bonczek received a grant of options to purchase 100,000 shares of common stock at $17.625 per share. If Mr. Bonczeks employment is terminated for any reason other than for cause, Mr. Bonczeks agreement provides that he is

In February 2004, we entered into an employment agreement with
Mr. Creech, our former Vice President of Finance. Under this agreement, Mr. Creech is entitled to receive minimum annual compensation of $172,000, an annual bonus based upon the achievement of certain milestones and all health insurance and other

benefits from the date of such termination until February 2005. This agreement expired according to its terms upon Mr. Creechs termination of employment in November 2004 with no further obligations on the part of the Company.



In June 2004, we entered into an employment agreement with Dr. Koszalka, our
Executive Vice President of Commercial Operations. Under this agreement, Dr. Koszalka is entitled to receive minimum annual compensation of $235,000, an annual bonus based upon the achievement of certain milestones and all health insurance and other

year from the date of such termination. The agreement is set to expire in June 2006 and shall automatically renew for a one-year period unless terminated earlier in accordance with its terms.



In September 2004, we entered into an employment agreement with Mr. Skolsky,
our Chief Executive Officer. The employment agreement has an initial term of two years and thereafter will automatically be extended for two year periods unless notice of non-renewal is given by either party no later than 90 days prior to the end of
the expiration of



11

each term. Under the agreement, Mr. Skolsky will receive an annual salary of $450,000, as well as other compensation, including bonus opportunities based
upon the achievement of financial and other performance criteria. In addition, under the agreement, Mr. Skolsky received a grant of an option to purchase 350,000 shares of the Companys common stock and a grant of 50,000 shares of restricted
stock. Both the option grant and the restricted stock grant are subject to the terms of the Companys Amended and Restated Stock Incentive Plan. In the event that Mr. Skolskys employment is terminated other than for Cause, death or
Disability or upon his resignation for Good Reason (as these terms are defined in the agreement), Mr. Skolsky will be entitled to certain severance payments and benefits, including two times his base salary plus his Target Bonus (as defined in the
Employment Agreement). Mr. Skolsky will also be entitled to a pro rata bonus for the year of termination based on actual results for such year if he is terminated due to death, Disability, termination without Cause, or upon resignation for Good
Reason. Mr. Skolsky is subject to non-competition restrictions during the term of his employment and for one year thereafter. In the event that the payment of benefits is due as a result of a Change of Control, the Company is required to pay any
excise taxes that may apply to such benefits. Mr. Skolsky is entitled to receive reimbursement for financial planning and tax preparation (including a gross-up for any taxes incurred on payment for these services) up to a maximum of $10,000 per
year.



401(k) Plan



The Company sponsors a 401(k) Profit Sharing Plan (the 401(k)
Plan) under Section 401(k) of the Internal Revenue Code covering all qualified employees. Participants may elect a salary reduction from 1% to 75% as a contribution to the 401(k) Plan, up to the annual Internal Revenue Service allowable
contribution limit. Modifications of the salary reductions may be made quarterly. The 401(k) Plan permits the Company to match participants contributions. Beginning in 1998, the Company matched up to 100% of a participants contributions
with Company stock, provided the participant was employed on the last day of the year. Matching contribution shares vest ratably based on a participants years of service and are fully vested after four years of service.



Compensation Committee Interlocks and Insider Participation



Our Board of Directors Compensation Committee is responsible for
determining the salaries and incentive compensation of the executive officers and providing recommendations for the salaries and incentive compensation of all other employees and consultants. The Compensation Committee also administers our benefit
plans, including the Amended and Restated Stock Incentive Plan. Dr. Cook serves as the Chairman of the Compensation Committee and the other members of the committee are Mr. Lipton, Dr. Sanders, Mr. Tang and Felix J. Baker. None of Dr. Cook,
Dr. Baker, Mr. Lipton, Dr. Sanders or Mr. Tang has served as an officer or employee of Trimeris or has any relationship with Trimeris requiring disclosure under SEC regulations.



Director Compensation



We reimburse our directors for all reasonable and necessary travel and other incidental expenses incurred in connection with their attendance at meetings
of the Board. Directors do not receive additional compensation in connection with their attendance at meetings. In addition, all eligible non-employee directors, except the Chairman, automatically receive a grant of an option on the date of our
annual meeting to purchase 10,000 shares of common stock. The Chairman automatically receives a grant of an option on the date of our annual meeting to purchase 15,000 shares of common stock. In addition, all eligible non-employee directors serving
as members of the Compensation Committee or Audit and Finance Committee, except the directors serving as chairmen of these committees, receive an option on the date of our annual meeting to purchase 1,250 shares of common stock. The directors
serving as chairmen of these committees each receives a grant of an option at the date of our annual meeting to purchase 2,500 shares of common stock. These options have an exercise price equal to 100% of the fair market value of our common stock on
the grant date and become exercisable after the completion of one year of service following the grant. Newly-elected directors are granted an option to purchase 20,000 shares of common stock, with the options vesting ratably over the three years.
These options have an exercise price equal to 100% of the fair market value of our common stock on the grant date. Members of the Nomination and Governance Committee do not receive any compensation for serving on this committee.



Compensation Committee Report on Executive Compensation



The Compensation Committee of the Board of Directors offers this report
regarding compensation for our executive officers, including our Chief Executive Officer. The Compensation Committee is composed entirely of independent



12



---

directors (as defined in the Nasdaq listing standards) and is responsible for developing and making recommendations to the Board with respect to our
executive compensation policies and practices, including the establishment of the annual total compensation for all executive officers, including our Chief Executive Officer.



General Compensation Policy.    Our primary objective is to maximize the value of our shares over
time. The Compensation Committee, with this objective in mind, authorizes compensation packages for our executive officers designed to retain and attract top quality management and to encourage them to contribute to the achievement of our business
objectives. In addition, the Committee attempts to establish compensation packages that are comparable to the packages received by executives of similar companies, in our industry.



We compensate our executive officers with a combination of salary and incentives designed to encourage efforts to achieve
both our short-term and long-term goals. The compensation structure attempts to reward both individual contributions and our overall corporate performance. The Committee evaluates corporate performance and makes executive compensation decisions from
various performance measures such as sales growth, earnings per share, achieving milestones in the development of drug candidates and raising capital needed for operations.



Section 162(m) of the Code limits the federal income tax deductibility of compensation paid to Trimeris five most
highly compensated executive officers. Under this section of the Code, the Company generally may deduct compensation paid to any such officer to the extent that it does not exceed $1 million during any calendar year or is
performance-based as defined in Section 162(m). The Compensation Committee expects that the deductibility limit of Section 162(m) will not currently have a significant effect on the Company. Current cash compensation paid to each of the
Companys executives is less than $1 million per year and is thus generally fully deductible to Trimeris.



The basic components of our compensation packages for our executive officers include the following:



| |  |  | Base Salary
| | - |  | -----------



| |  |  | Performance Incentive Awards
| | - |  | ----------------------------



| |  |  | Long-term Incentives
| | - |  | --------------------



| |  |  | Benefits
| | - |  | --------



Each executive officers compensation package contains a mix of these components and is designed to provide a level of compensation competitive with the compensation paid to comparable officers of similar
biopharmaceutical companies. The Committee favors a compensation structure that aligns the long-term interests of its executive officers with the interests of its stockholders, and as a result places significant weight upon long-term incentives in
the form of equity compensation.



Base
Salary.    Base salary and increases in base salary are determined by both individual and Company performance, as well as the salary levels in effect for similar biopharmaceutical companies. During 2004, the Committee
attempted to keep the base salaries of our officers at a level consistent with the median range of the salaries of equivalent officers in similar biopharmaceutical companies. In addition, the Committee considered the following factors in setting the
base salaries for executive officers during 2005: our sales of FUZEON, achievement of cost and earnings objectives, our progress in the development of next generation fusion inhibitors, and contributions in any area of special expertise by a
particular executive.



Performance Incentive
Awards.    Performance incentive awards are granted by the Committee based upon its evaluation of the performance of each executive officer and the achievement of our goals during the year. Payment of bonuses occurs as soon
as practical in the following calendar year. In February 2005, bonuses totaling $382,000 were awarded to the Named Executive Officers for achievements in 2004, which included increases in FUZEON sales and progress in the development of a third
generation clinical candidate.



Long-term Incentive
Compensation.    Long-term incentive compensation in the form of stock-based awards is expected to be the largest element of total compensation over time in order to conserve our cash resources, to align the long-term
interests of each officer with the interests of our stockholders and to provide long-term incentives for the individual officer to remain with us. Grants are generally made to most employees on their date of hire based on salary level and position.
Under our stock option plan, stock option grants made in connection with commencement of employment are priced at the fair market value on the date of grant, generally become exercisable over a period of four years and have a term of up to ten
years. All employees, including executive officers, are eligible for subsequent discretionary grants, which are generally based on corporate and/or individual performance. During the period covering



13



---

2000-2004, the number of options to be granted was determined each June. The options were granted in June, October, January and April at the fair market
value of our common stock on the date of each grant. In order to receive the quarterly grant, the individual employee was required to be employed on the date of grant. Prior to 2000, discretionary grants were awarded on an annual basis at the fair
market value on the date of grant and became exercisable over a period of four years. The size of the stock option grant to each officer is based on the officers current position and expected future contributions to our business. Awards of
stock options are designed to have an expected aggregate exercise value over time equal to a multiple of salary, which are expected to create a significant value opportunity based upon stock ownership. Restricted stock grants include a restriction
that lapses after three years of service with the Company and are subject to the provisions of the Amended and Restated Stock Incentive Plan.



Benefits.    Benefits offered to our executive officers are substantially the same as those offered to all our regular
employees and generally include medical insurance, dental insurance, 401(k) plan, employee stock purchase plan, disability insurance, life insurance and flexible spending account.



CEO COMPENSATION



Mr. Skolskys compensation in 2004, including base salary, bonus award and stock-based incentive grants was determined within the same general
framework established for all executive officers of the Company. However, in light of the fact that 2004 was the first year of Mr. Skolskys employment, the Committee also considered the requirements of attracting a top-level executive to the
Company.



Mr. Skolskys 2004 base salary of $450,000 was
arrived at using various surveys regarding executive compensation at similar biopharmaceutical companies. Prior to the Committee establishing Mr. Skolskys bases salary for 2004, the Committee conducted an extensive study of compensation for
officers with similar responsibilities in similar biopharmaceutical companies.



Mr. Skolskys target bonus is set by contract to range from 25% -75% of his base salary based on financial and other criteria set by the board in consultation with Mr. Skolsky. Mr. Skolskys bonus award was
$70,000 for 2004, which was pro rated for his partial year of service. The Committee based the bonus on objectives relating to FUZEON sales and other personal objectives.



In September 2004, we entered into an employment agreement with Mr. Skolsky, to serve as our Chief Executive Officer and a
member of our Board of Directors. The employment agreement has an initial term of two years and thereafter will automatically be extended for two year periods unless notice of non-renewal is given by either party no later than 90 days prior to the
end of the expiration of each term. Under the agreement, Mr. Skolsky will receive an annual salary of $450,000, as well as other compensation, including bonus opportunities based upon the achievement of financial and other performance criteria. In
addition, under the agreement, Mr. Skolsky received a grant of an option to purchase 350,000 shares of the Companys common stock and a grant of 50,000 shares of restricted stock. Both the option grant and the restricted stock grant are subject
to the terms of the Companys Amended and Restated Stock Incentive Plan. For a detailed discussion of Mr. Skolskys employment agreement, please refer to the section entitled Employment Agreements on page 11 of this Amendment
No. 1.



The Committee expects that stock options will represent
the largest element of Mr. Skolskys compensation and will provide a direct link between Mr. Skolskys compensation and the Companys performance overall. The Committee believes that Mr. Skolskys inducement package was
appropriate to attract an executive of Mr. Skolskys background and experience and are comparable to the compensation offered to chief executive officers in similar biopharmaceutical companies. In addition, it is the Committees judgment
that Mr. Skolskys commercial experience and management leadership skills are extremely important to the Company, and it is therefore essential to provide Mr. Skolsky with a significant unvested stock ownership position.

investment power with respect to all shares of common stock shown as beneficially owned by them. Options to purchase shares of common stock that are exercisable within 60 days of April 26, 2005 are deemed to be beneficially owned by the person
holding such options for the purpose of computing ownership of such person, but are not treated as outstanding for the purpose of computing the ownership of any other person. Applicable percentage of beneficial ownership is based on 21,949,847
shares of common stock outstanding as of April 26, 2005.



Unless otherwise indicated in the footnotes, the address for each listed stockholder is: c/o Trimeris, Inc., 3500 Paramount Parkway, Morrisville, North Carolina 27560.

Pre-Approval Policy and Procedures



The Audit Committee has adopted a policy that requires
advance approval of all audit, audit-related, tax and other services performed by the independent registered public accounting firm. During the year, circumstances may arise when it becomes necessary to engage the independent auditor for additional
services that are not contemplated in the original pre-approval. In those instances, the Audit Committee requires specific pre-approval before engaging the independent auditor. The Audit Committee has delegated to the chair of the Audit Committee
the authority to pre-approve audit related and non-audit services not prohibited by law to be performed by the Companys independent registered public accounting firm and associated fees up to a maximum for any one audit-related or non-audit
service of $5,000 per service in a calendar year. The chairman is required to report, for informational purposes only, any pre-approval decisions that have been made to the Audit Committee at its next scheduled meeting. The Audit Committee is
prohibited from delegating to management its responsibilities to pre-approve services performed by the independent auditor.
