     Novo Nordisk has certain rights under a collaborative research and
development agreement which it entered into with the Company in August 1993.
Novo Nordisk also made an equity investment in the Company pursuant to an equity
agreement with the Company in August 1993. Under the collaborative research and
development agreement, Novo Nordisk will make milestone payments and support the
Company's multiple sclerosis (MS), myasthenia gravis (MG), and insulin dependent
diabetes research and development programs. In exchange, Novo Nordisk will have
world-wide rights to products developed under the agreement, including rights to
commercialize these products. Anergen has retained rights of co-promotion in
North America for therapeutics in MS and MG. The research and development
agreement provides that both companies will contribute to manufacturing
processes and upon product commercialization, Anergen is to receive royalty
payments from Novo Nordisk based on product sales. Novo Nordisk had the right to
terminate its obligations under the research and development agreement after a
36-month period ending in August 1996, but in March 1996 it agreed to extend the
agreement by an additional two year period. Under the research and development
agreement, the Company recorded revenues for research and development of $3.1,
$3.0 and $2.3 million in 1996, 1995 and 1994, respectively. Under the equity
agreement, Novo Nordisk purchased 1,219,745 shares of the Company's Common Stock
for $8 million with certain rights to obtain additional shares in the future.
Also under the equity agreement Novo Nordisk had the right to designate one
nominee to the Board of Directors as long as their ownership percentage of the
Company's Common Stock remained above 10% of the outstanding capital stock.
Currently, Novo Nordisk's ownership is less than 10% of the Company's
outstanding capital stock. Bruce L. A. Carter, Ph.D., an officer of Novo
Nordisk, is currently nominated to the Company's Board.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
     On March 10, 1995 the Company signed a Common Stock Purchase Agreement (the
"Agreement") with Warburg, Pincus Ventures, L.P. ("Warburg") and International
Biotechnology Trust PLC ("IBT") (collectively, the "Purchasers") to purchase
7,317,073 shares of Common Stock for approximately $15 million. The new shares
were priced at the average closing bid price for the Company's Common Stock over
a 30 day trading period. This transaction was approved by the Company's
shareholders and was completed on April 13, 1995. The Purchasers have the right
at any time after thirty (30) months from April 13, 1995 to request the Company
to effect a registration of at least 30% of the aggregate number of shares held
by the requesting Purchaser or any lesser percentage if the aggregate net
offering price would exceed $1,000,000. The Purchasers also have the right to
have their shares included in a registration by the Company of its securities
for its own account or the account of any of its shareholders. The Purchasers
have certain rights of representation on the Company's Board of Directors based
on certain minimum levels of ownership of the Company's Common Stock. Under the
Agreement, the Company is currently obligated to include in the slate of
nominees recommended by the Board of Directors and management at each election
of directors two candidates selected by Warburg, one candidate selected by IBT
and one candidate as mutually agreed to by IBT and Warburg. Upon the closing of
this transaction, the Board of Directors appointed to the Board to fill
vacancies two new members representing Warburg, Mr. Nicholas J. Lowcock and Mr.
James E. Thomas, and one new member representing IBT, Ms. Nicole Vitullo. These
three individuals have been nominated to the Board in connection with the
current election of directors, and it is expected that during the current fiscal
year, IBT and Warburg will identify an appropriate industry representative for
nomination to the Board pursuant to their right to designate such candidate
under the Agreement.
 
     In March 1996, the Company and Novo Nordisk agreed to expand their
collaborative research and development agreement to establish certain milestones
for products developed under the agreement and to extend the term of the
development program by an additional two-year period through August 1998. Bruce
L.A. Carter, the Corporate Executive Vice President and Chief Scientific Officer
of Novo Nordisk, has served as a director of the Company since February 1994.
 
     In May 1996, the Company entered into an employment agreement with Dr.
Barry M. Sherman, President and Chief Executive Officer and a director of the
Company. In February 1996, the Company entered into a transition agreement with
John W. Fara, Ph.D., the Company's former President and Chief Executive Officer.

Termination and Change of Control Arrangements."
 
                             EMPLOYEE BENEFIT PLANS
 
     The following is a brief summary of plans in effect during the fiscal year
ended December 31, 1996 under which officers, directors and employees of the
Company received benefits. The closing price of the Company's Common Stock
reported on the NASDAQ National Market on the Record Date was $4.0625 per share.
 
401(k) PLAN
 
     In January of 1992 the Company adopted a tax-qualified employee savings and
retirement plan (the "401(k) Plan"), which generally covers all of the Company's
full-time employees who have attained age 21. Pursuant to the 401(k) Plan,
employees may elect to defer up to 15% of their current compensation (subject to
certain statutorily prescribed limits, including an annual limit of $9,500 in
1996). These deferred amounts are contributed to the 401(k) Plan. The 401(k)
Plan permits, but does not require, additional matching and Company
contributions on behalf of participants. Since the Plan's inception, the Company
has contributed an amount equal to 50% of each participant's contribution for up
to 2% of their eligible compensation. The
 
                                        7
<PAGE>   10
 
401(k) Plan is intended to qualify under Sections 401(k) and 401(a) of the
Internal Revenue Code of 1986, as amended (the "Code"). Contributions to such a
qualified plan are deductible to the Company when made and neither the
contributions nor the income earned on those contributions is taxable to
participants until withdrawn. All 401(k) Plan contributions are credited to
separate accounts maintained in trust by two individual trustees. Contributions
are invested, at the participant's direction, in one or more of the investment
funds available under the 401(k) Plan. All account balances are adjusted at
least annually to reflect the investment earnings and losses of the trust fund.
Each participant is fully vested in his or her salary deferral accounts under
the 401(k) Plan. Distributions may be made from a participant's account pursuant
to the 401(k) Plan's hardship withdrawal provisions as well as upon a
participant's termination of employment, disability or attainment of age 59 1/2.
Distributions will be in the form of a lump sum, installment payments or an
annuity, in the participant's discretion. Federal tax laws limit the amount that
may be added to a participant's accounts for any one year under a qualified plan
such as the 401(k) Plan to the lesser of (i) $30,000 or (ii) 25% of the
participant's compensation (net of salary deferral contributions) for the year.
 
1991 EMPLOYEE STOCK PURCHASE PLAN
 
     The Company's 1991 Employee Stock Purchase Plan (the "Purchase Plan") is
intended to qualify under Section 423 of the Code. The Purchase Plan was amended
by the Board in March 1996 to increase the number of shares available for
issuance thereunder. A total of 250,000 shares of Common Stock are reserved for
issuance under the Purchase Plan. Under the Purchase Plan, the Company withholds
a specified percentage of each salary payment to participating employees over
certain offering periods. Unless the Board of Directors or its committee
determines otherwise, each offering period runs for 24 months and is divided
into four consecutive purchase periods of six months each.
 
     The price at which stock is purchased under the Purchase Plan is equal to
85% of the fair market value of the Common Stock on the first day of the
applicable offering period (net initial public offering price received by the
Company for the first offering period) or the last day of the applicable
purchase period, whichever is lower. To the extent permitted by Rule 16b-3, if
the purchase price of the Common Stock at the end of a purchase period in any
offering period is lower than the purchase price at the beginning of that
offering period, then all participants in that offering period are automatically
withdrawn from that offering period immediately after the exercise of their
options and automatically re-enrolled in the immediately following offering
period.
 
     As of December 31, 1996, a total of 161,667 shares of Common Stock have
been issued to employees at an aggregate purchase price of $529,562 and a
weighted average purchase price of $3.28 per share pursuant to offerings under
the Purchase Plan and 88,333 shares remained available for future issuance under
the Purchase Plan.
 
     The following table sets forth as to the executive officers named in the
table under "Executive Compensation" who purchased shares pursuant to the
Purchase Plan, all current executive officers as a group and all other employees
as a group (i) the number of shares of the Company's Common Stock purchased

1996; (ii) the aggregate purchase price thereof and (iii) the fair value of
stock purchased through December 31, 1996 under the Purchase Plan:

1988 STOCK OPTION PLAN
 
     A total of 1,800,000 shares of the Company's Common Stock has been reserved
for issuance under the Company's 1988 Stock Option Plan (the "Option Plan")
adopted by the Board of Directors in 1988 and amended in 1990, 1991, 1992 and
1995. The Option Plan expires by its own terms in 1998. At December 31, 1996,
options to purchase 1,292,801 shares were outstanding at a weighted average
exercise price of $4.74 per share and 430,775 options had been exercised.
 
     The Option Plan provides for the grant of "incentive stock options" within
the meaning of Section 422 of the Code and nonqualified stock options to
employees, directors and consultants of the Company. Incentive stock options may
be granted only to employees. The Option Plan is administered by the Board of
Directors, which determines the terms of options granted, including the exercise
price, the number of shares subject to the option, and the option's
exercisability. Options granted to employees are generally immediately
exercisable, but typically vest at the rate of 6/48ths of the shares after six
months and an additional 1/48th of the shares per month thereafter.
 
     The Option Plan requires that the exercise price of incentive stock options
must be at least equal to the fair market value of such shares on the date of
grant and the exercise price of nonqualified stock options must be at least 85%
of the fair market value of such shares on the date of the grant. The maximum
term of options granted under the Option Plan is ten years. With respect to any
participant who owns stock possessing more than 10% of the voting rights of the
Company's outstanding capital stock, the exercise price of any option must be at
least equal to 110% of fair market value on the date of grant and the term may
be no longer than five years.
 
     Pursuant to the Option Plan, in the event of certain mergers of the Company
with other entities, transfers of voting control of the Company's capital stock
or sales of all or substantially all of the Company's assets, the Company will
request that the acquiring entity assume the Company's rights and obligations
under the Option Plan or provide similar options in substitution therefor. If
the acquiring entity chooses not to assume such rights and obligations or
provide substitute options, then the Company's Board of Directors will cause all
outstanding options (together with shares purchased upon exercise thereof) to
become fully vested prior to the event causing such acceleration and all
unexercised options will terminate upon completion of such event.
 
     Please see "Executive Compensation and Other Matters -- Executive
Compensation -- Option Grants in Fiscal 1996" for information with respect to
the grant of options to the executive officers during fiscal 1996. During the
fiscal year ended December 31, 1996, all current executive officers as a group
and all employees as a group were granted options to purchase 425,000 shares and
535,000 shares, respectively, at a weighted average exercise price of $3.72 per
share, pursuant to the Option Plan.
 
1992 CONSULTANT STOCK PLAN
 
     A total of 50,000 shares of the Company's Common Stock has been reserved
for issuance under the Company's 1992 Consultant Stock Plan (the "Consultant
Plan") adopted by the Board of Directors in 1992. This plan allows the Company
to compensate consultants in Company stock rather than cash in certain
situations where the Company deems it desirable. At December 31, 1996, 12,659
shares had been issued under the Consultant Plan.
 
1995 DIRECTOR OPTION PLAN.
 
     A total of 200,000 shares of the Company's Common Stock has been reserved
for issuance under the Company's 1995 Director Option Plan (the "Director
Plan"), adopted by the Board of Directors in 1995. The Director Plan expires by
its own terms in 2005. At December 31, 1996, options to purchase 20,000 shares
were outstanding at a weighted average exercise price of $3.72 per share and no
options had been exercised.
 
     The Director Plan provides for the grant of "nonstatutory options" to
non-employee directors of the Company. The Director Plan is administered by the
Board of Directors. All grants of options under the Director Plan are automatic
and non-discretionary pursuant to the terms of the Director Plan. Each non-
employee director is automatically granted a nonstatutory option to purchase
25,000 shares of Common Stock on the date such person first becomes a director
(provided that non-employee directors who were directors on
 
                                        9
<PAGE>   12
 
the effective date of the Director Plan were granted a nonstatutory option to
purchase 5,000 shares in lieu of such grant). On the first day of each fiscal
year thereafter, each incumbent non-employee director will automatically be
granted a nonstatutory option to purchase 5,000 shares of Common Stock (provided
such person has served on the Board at least six months). Options granted to
directors are generally immediately exercisable, but typically vest at the rate
of 1/48th of the shares per month after the date of grant. The Director Plan
requires that the exercise price of nonstatutory stock options is equal to the
fair market value of such shares on the date of grant. The term of options
granted under the Director Plan is ten years. In the event of certain mergers of
the Company with other entities, transfers of voting control of the Company's
capital stock or sales of all or substantially all of the Company's assets, all
outstanding options shall become fully vested.
 
     As of December 31, 1996, only Dr. Harden McConnell and Mr. Harry H. Penner,
Jr. participated in the Director Plan.
 
                                 PROPOSAL NO. 2
 
                  APPROVAL OF ADOPTION OF THE 1996 STOCK PLAN
 
     At the Annual Meeting, the shareholders are being asked to approve adoption
of the Company's 1996 Stock Plan (the "Plan") and to approve 1,000,000 shares
reserved for issuance under the Plan.
 
     In October 1996, the Board of Directors adopted the Plan and reserved
1,000,000 shares of Common Stock for issuance thereunder subject to shareholder
approval. As of February 1, 1997, 20,000 options had been granted pursuant to
the Plan at a weighted average exercise price of $4.00 per share and no options
had been exercised. The Plan is designed to retain, motivate and reward
employees and executives by providing such personnel long term equity
participation in the Company relating directly to the financial performance and
long-term growth of the Company.
 
     In 1993, Section 162(m) was added to the Internal Revenue Code of 1986, as
amended. Section 162(m) limits the Company's deduction in any one fiscal year
for federal income tax purposes to $1,000,000 per person with respect to the
Company's Chief Executive Officer and its four other highest paid executive
officers who are employed on the last day of the fiscal year unless the
compensation was not otherwise subject to the deduction limit. Compensation
which is performance based and approved by the Company's stockholders is not
subject to the deduction limit. Therefore, in order to maximize the Company's
federal income tax deductions, the Board of Directors of the Company is
requesting that the stockholders approve the adoption of the Plan at the Annual
Meeting.
 
     The approval of the adoption of the Plan requires the affirmative vote of
the holders of a majority of the shares of the Company's Common Stock
represented, in person or by proxy, and voting at the Annual Meeting.
 
SUMMARY OF THE PLAN
 
     General. The purpose of the Plan is to attract and retain the best
available personnel for positions of substantial responsibility with the
Company, to provide additional incentive to the employees, directors and
consultants of the Company and to promote the success of the Company's business.
Options granted under the Plan may be either "incentive stock options," as
defined in Section 422 of the Internal Revenue Code of 1986, as amended (the
"Code"), or nonstatutory stock options.
 
     Administration. The Plan may generally be administered by the Board or a
committee appointed by the Board (the "Administrator"). Subject to the other
provisions of the Plan, the Board has broad authority to administer the Plan
including the authority to (i) interpret the Plan and apply its provisions; (ii)
prescribe, amend or rescind rules and regulations relating to the Plan; (iii)
select the persons to whom options are to be granted; (iv) determine the number
of shares to be made subject to each option; (v) determine whether and to what
extent options are to be granted; (v) prescribe the terms and conditions of each
option (including the exercise price, whether an option will be classified as an
incentive stock option or a nonstatutory stock option
 
                                       10
<PAGE>   13
 
and the provisions of the stock option agreement to be entered into between the
Company and the grantee); (vii) amend any outstanding option subject to
applicable legal restrictions; (viii) authorize any person to execute, on behalf
of the Company, any instrument required to effect the grant of an option; and
(ix) take any other actions deemed necessary or advisable for the administration
of the Plan. All decisions, interpretations and other actions of the
Administrator shall be final and binding on all holders of options and on all
persons deriving their rights therefrom.
 
     Eligibility; Limitations. Nonstatutory stock options may be granted under
the Plan to employees, directors and consultants of the Company and any parent
or subsidiary of the Company. Incentive stock options may be granted only to
employees. Any optionee who owns more than 10% of the combined voting power of
all classes of outstanding stock of the Company is not eligible for the grant of
an incentive stock option unless the exercise price of the option is at least
110% of the fair market value of the Common Stock on the date of grant.
 
     Section 162(m) of the Code places limits on the deductibility for federal
income tax purposes of compensation paid to certain executive officers of the
Company. In order to preserve the Company's ability to deduct the compensation
income associated with options granted to such persons, the Plan provides that
no employee may be granted, in any fiscal year of the Company, options to
purchase more than 500,000 shares of Common Stock. Notwithstanding this limit,
however, in connection with an employee's initial employment, he or she may be
granted options to purchase up to an additional 500,000 shares of Common Stock.
 
     Terms and Conditions of Options. Each option granted under the Plan is
evidenced by a written stock option agreement between the Company and the
optionee, and is subject to the following additional terms and conditions:
 
          (a) Exercise Price. The Administrator determines the exercise price of
     options at the time the options are granted. The exercise price of an
     incentive stock option may not be less than 100% of the fair market value
     of the Common Stock on the date such option is granted; provided, however,
     the exercise price of an incentive stock option granted to a 10%
     shareholder may not be less than 110% of the fair market value of the
     Common Stock on the date such option is granted. The fair market value of
     the Common Stock is generally determined with reference to the closing sale
     price for the Common Stock (or the closing bid if no sales were reported)
     on the last market trading day prior to the date the option is granted. The
     exercise price of a nonstatutory stock option may be determined by the
     Administrator; provided, however, the exercise price of a nonstatutory
     stock option intended to qualify as "performance-based compensation" within
     the meaning of Section 162(m) of the Code may not be less than 100% of the
     fair market value of the Common Stock on the date of grant.
 
          (b) Exercise of Option. The Administrator determines when options
     become exercisable, and may in its discretion, accelerate the vesting of
     any outstanding option. Stock options granted under the Plan generally vest
     and become exercisable over four years.
 
          (c) Form of Consideration. The means of payment for shares issued upon
     exercise of an option is specified in each option agreement. The Plan
     permits payment to be made by cash, check, promissory note, other shares of
     Common Stock of the Company (with some restrictions), cashless exercise, a
     reduction in the amount of any Company liability to the optionee, any other
     form of consideration permitted by applicable law, or any combination
     thereof.
 
          (d) Term of Option. The term of an incentive stock option may be no
     more than ten (10) years from the date of grant; provided that in the case
     of an incentive stock option granted to a 10% shareholder, the term of the
     option may be no more than five (5) years from the date of grant. No option
     may be exercised after the expiration of its term.
 
          (e) Termination of Employment. If an optionee's employment or
     consulting relationship terminates for any reason (other than death or
     disability), then all options held by the optionee under the Plan expire on
     the earlier of (i) the date set forth in his or her notice of grant or (ii)
     the expiration date of such option. To the extent the option is exercisable
     at the time of such termination, the optionee may exercise
 
                                       11
<PAGE>   14
 
     all or part of his or her option at any time before termination. In the
     absence of a specified time specified in the option agreement, the option
     must be exercised within three months following termination.
 
          (f) Permanent Disability. If an optionee's employment or consulting
     relationship terminates as a result of permanent and total disability (as
     defined in the Code), then all options held by such optionee under the Plan
     will expire on the earlier of (i) twelve (12) months from the date of
     termination of the optionee's employment or (ii) the expiration date of the
     option. The optionee may exercise all or part of his or her option at any
     time before such expiration to the extent that such option was exercisable
     at the time of termination of employment.
 
          (g) Death. If an optionee dies while employed by the Company, his or
     her option will expire upon the earlier of (i) twelve (12) months after the
     optionee's death or (ii) the expiration date of the option. The executor or
     other legal representative of the optionee's estate may exercise all or
     part of the optionee's option at any time before such expiration to the
     extent that such option was exercisable at the time of optionee's death.
 
          (h) Nontransferability of Options. Options granted under the Plan
     generally are not transferable other than by will or the laws of descent
     and distribution, and may be exercised during the optionee's lifetime only
     by the optionee. However, the Administrator may, in its discretion, provide
     for the transfer of options to any member of the optionee's immediate
     family. Following such transfer, any such options will continue to be
     subject to the same terms and conditions as were applicable immediately
     prior to the transfer.
 
          (i) Value Limitation. If the aggregate fair market value of all shares
     of Common Stock subject to an optionee's incentive stock option which are
     exercisable for the first time during any calendar year exceeds $100,000,
     the excess options will be treated as nonstatutory stock options.
 
          (j) Other Provisions. The stock option agreement may contain other
     terms, provisions and conditions not inconsistent with the Plan as may be
     determined by the Administrator.
 
     Adjustments Upon Changes in Capitalization. In the event that the stock of
the Company changes by reason of any stock split, reverse stock split, stock
dividend, combination, reclassification or other similar change in the capital
structure of the Company effected without the receipt of consideration,
appropriate adjustments will be made in the number and class of shares of stock
subject to the Plan, the number and class of shares of stock subject to any
option outstanding under the Plan, and the exercise price of any such
outstanding option.
 
     In the event of a liquidation or dissolution, any unexercised options will
terminate. The Administrator may, in its discretion, provide that each optionee
will have the right to exercise all of the optionee's options, including those
not otherwise exercisable, until the date ten (10) days prior to the
consummation of the liquidation or dissolution.
 
     In connection with any merger, consolidation, acquisition of assets or like
occurrence involving the Company, each outstanding option will be assumed or an
equivalent option substituted by the successor corporation. If the successor
corporation refuses to assume the options or to substitute substantially
equivalent options, the optionee will have the right to exercise the option as
to all the optioned stock, including shares not otherwise exercisable. In such
event, the Administrator will notify the optionee that the option is fully
exercisable for fifteen (15) days from the date of such notice and that the
option terminates upon expiration of such period.
 
     Amendment and Termination of the Plan. The Board may amend, alter, suspend
or terminate the Plan, or any part thereof, at any time and for any reason.
However, the Company will obtain shareholder approval for any amendment to the
Plan to the extent necessary to comply with Section 162(m) and Section 422 of
the Code, or any similar rule or statute. No such action by the Board or
shareholders may alter or impair any option previously granted under the Plan
without the written consent of the optionee. Unless terminated earlier, the Plan
will terminate ten years from the date of its approval by the shareholders or
the Board, whichever is earlier.

FEDERAL INCOME TAX CONSEQUENCES
 
     Incentive Stock Options. An optionee who is granted an incentive stock
option does not recognize taxable income at the time the option is granted or
upon its exercise, although the exercise may subject the optionee to the
alternative minimum tax. Upon a disposition of the shares more than two years
after grant of the option and one year after exercise of the option, any gain or
loss is treated as long-term capital gain or loss. If these holding periods are
not satisfied, the optionee recognizes ordinary income at the time of
disposition equal to the difference between the exercise price and the lower of
(i) the fair market value of the shares at the date of the option exercise or
(ii) the sale price of the shares. Any gain or loss recognized on such a
premature disposition of the shares in excess of the amount treated as ordinary
income is treated as long-term or short-term capital gain or loss, depending on
the holding period. A different rule for measuring ordinary income upon such a
premature disposition may apply if the optionee is also an officer, director, or
10% shareholder of the Company. The Company is entitled to a deduction in the
same amount as the ordinary income recognized by the optionee.
 
     Nonstatutory Stock Options. An optionee does not recognize any taxable
income at the time he or she is granted a nonstatutory stock option. Upon
exercise, the optionee recognizes taxable income generally measured by the
excess of the then fair market value of the shares over the exercise price. Any
taxable income recognized in connection with an option exercise by an employee
of the Company is subject to tax withholding by the Company. The Company is
entitled to a deduction in the same amount as the ordinary income recognized by
the optionee. Upon a disposition of such shares by the optionee, any difference
between the sale price and the optionee's exercise price, to the extent not
recognized as taxable income as provided above, is treated as long-term or
short-term capital gain or loss, depending on the holding period.
 
     THE FOREGOING IS ONLY A SUMMARY OF THE EFFECT OF FEDERAL INCOME TAXATION
UPON OPTIONEES AND THE COMPANY WITH RESPECT TO THE GRANT AND EXERCISE OF OPTIONS
UNDER THE PLAN. IT DOES NOT PURPORT TO BE COMPLETE, AND DOES NOT DISCUSS THE TAX
CONSEQUENCES OF THE EMPLOYEE'S OR CONSULTANT'S DEATH OR THE PROVISIONS OF THE
INCOME TAX LAWS OF ANY MUNICIPALITY, STATE OR FOREIGN COUNTRY IN WHICH THE
EMPLOYEE OR CONSULTANT MAY RESIDE.

COMPENSATION OF DIRECTORS
 
     Directors currently receive no fees for services provided in that capacity
but are reimbursed for out-of-pocket expenses in connection with attendance at
Board of Directors' meetings. During 1996, Dr. McConnell was paid $12,000 by the
Company in connection with consulting services provided to the Company. Outside
directors are granted nonstatutory stock options under the 1995 Director Option
Plan. Currently there are six Outside Directors, but only two have elected to
receive grants of options under the 1995 Director Option Plan. Please see
"Employee Benefit Plans -- 1995 Director Option Plan" for information with
respect to the 1995 Director Option Plan.
 
EMPLOYMENT CONTRACTS, TERMINATION AND CHANGE OF CONTROL ARRANGEMENTS
 
     In May 1996, the Company entered into an employment agreement with Barry M.
Sherman, M.D., effective in May 1996 providing for a base salary of $250,000 per
year and an option to purchase 400,000 shares of Common Stock at an exercise
price of $3.75 per share subject to a four-year vesting schedule. The term of
Dr. Sherman's employment agreement is through May 2000, subject to extension by
mutual agreement of both parties and subject to a voluntary termination by Dr.
Sherman or earlier termination by the Company with or without cause. If the
Company terminates Dr. Sherman without cause or constructively terminates Dr.
Sherman, Dr. Sherman is entitled to twelve months severance pay and accelerated
vesting of the lesser of the unvested portion or one-quarter of the options
referred to above (or the lesser of the unvested portion or one-half of such
options if the termination occurs after a change of control). At the end of
twelve months, Dr. Sherman is eligible to receive a performance bonus of up to
twenty-five percent of his annual salary based on full or partial completion of
certain goals established by mutual agreement of Dr. Sherman and the Board of
Directors.
 
     In February 1996, the Company entered into an agreement with John W. Fara,
Ph.D., the Company's former President and Chief Executive Officer, regarding his
retirement from the Company. On May 31, 1996, Dr. Fara formally resigned as
President and Chief Executive Officer and as a director of the Company. Dr. Fara
will serve the Company on a part-time employment basis. Under the agreement, Dr.
Fara continues to receive a salary at an annual rate of $250,000 for a period of
twelve months. Dr. Fara is also eligible for
 
                                       15
<PAGE>   18
 
bonuses for each substantial development or license agreement that the Company
enters into with certain third parties or in the event of a sale of all or
substantially all the Company's assets, merger or consolidation of the Company
with any other corporation or the acquisition of 40% or more of the Company's
outstanding Common Stock before November 30, 1996. Dr. Fara's stock options
continue to vest as long as he is employed on a part-time basis and when he is
no longer an employee all options to acquire shares of the Company's Common
Stock which were unvested as of such date become fully exercisable.
 
     The 1995 Director Option Plan provides that upon a change in control of the
Company, the unvested portion of all outstanding options under such Plan shall
become immediately exercisable. The 1988 Stock Option Plan and the 1992
Consultant Stock Plan, each provides that in the event of a change in control of
the Company, outstanding stock options and stock purchase rights under such
Plans shall be assumed or equivalent options or rights shall be substituted by
the successor entity. If such successor corporation does not agree to such
assumption or substitution, the Company's Board of Directors must provide for
such options or rights to become immediately exercisable in full. There are no
other compensatory plans or arrangements with respect to an executive officer
that will result in payments upon resignation, retirement, or any other
termination of such executive officer's employment or from a change of control
of the Company.
 
REPORT OF THE COMPENSATION COMMITTEE OF THE BOARD OF DIRECTORS
 
     The Compensation Committee has been a standing committee of the Board of
Directors of Anergen, Inc. since prior to the Company's initial public offering
on October 10, 1991. Throughout its history, only "outside", nonemployee
Directors have served on this committee. Among its other duties, the
Compensation Committee is charged with the responsibilities, subject to full
Board of Directors' approval, of establishing, periodically reevaluating and (as
appropriate) adjusting, and administering Company policies concerning the
compensation of management personnel, including the CEO and all other officers.
In discharging such duties, the Compensation Committee is responsible for
annually determining and recommending to the full Board the annual base salary
for each officer and for establishing the criteria under which cash incentive
bonuses may be paid to such officers for the year. In addition, the Committee is
responsible for administering the Company's Stock Option Plan.
 
     The Company uses a simple total compensation program that consists of cash-
and equity-based compensation. Having a compensation program that allows the
Company to successfully attract and retain key employees permits it to develop
its technology toward commercialization, enhance shareholder value, motivate
technological innovation, foster teamwork, and adequately reward employees.
 
     Cash Salaries and Bonuses. Base salaries for new officers are initially
established by evaluating the responsibilities of the position to be held and
the experience of the individual, and by reference to the competitive
marketplace for executive talent, including a comparison to base salaries for
comparable positions at other companies. Companies used in the comparison were
selected based upon comparable employee headcount, market capitalization and
stage of product progression. In determining its recommendations for annual
adjustment to officers' compensation packages, the Compensation Committee
focuses primarily on similar executive marketplace data, including survey
material on salary movements for peer executives, in determining base salary
adjustments. In the context of individual performance, Company performance,
survey data, and positions responsibility level, the Chief Executive Officer
recommended to the Committee a base salary for fiscal 1996 for each officer's
position, but excluding the Chief Executive Officer. The Compensation Committee
determined the Chief Executive Officer's salary adjustment considering these
same criteria. The officers' salaries for 1996 corresponded with the median
range of comparable companies. When evaluating and deciding upon cash bonuses
the Compensation Committee gives consideration to the individual's contributions
towards the Company's success in moving toward its long-term goals during the
fiscal year, the performance of the Common Stock during that year, and its
assessment of the quality of services rendered by the officer. Because the
Company is in the research and development stage the typical financial
performance methodology of evaluating the Company's performance is not
appropriate. Cash bonuses can be awarded at the Board's discretion for
exceptional contributions to the Company's success. The officers' performance is
directly related to corporate performance objectives, defined based upon
industry standards of progression towards the
 
                                       16
<PAGE>   19
 
development of pharmaceutical products, and bonuses are awarded based upon the
achievement of those objectives.
 
     Stock Option Program. The purpose of this program is to provide additional
incentives to employees who are expected to contribute materially to the
Company's success in the future. The Committee believes stock options encourage
the achievement of superior results over time and align officer and shareholder
interests. The option program also utilizes vesting periods to encourage key
employees to continue in the employ of the Company. The Company grants stock
options annually to a broad-based population of the total employee pool. The
size of the stock option grants to each officer are based upon the Board's
evaluation of the officer's contribution to the achievement of corporate
performance objectives. The Chief Executive Officer recommends to the Committee
proposed stock option grants for the Company's officers, other than the Chief
Executive Officer. Stock option grants to each officer other than the Chief
Executive Officer are reviewed and approved by the Committee in the context of
the following factors: the Company's performance to date relative to its
objectives, the responsibility level and performance of the officer, prior
option grants to the officer and the level of vested and unvested options. The
Compensation Committee determines the Chief Executive Officer's stock option
grant considering the same criteria.
 
     Compensation of Chief Executive Officer. The compensation of the Company's
Chief Executive Officer for 1996 was based upon the same general criteria as
described above for executive officers. Specifically, the Compensation Committee
considered several factors as important in determining the Chief Executive's
compensation in 1996. These factors included the attainment of certain research
and development objectives, the Company's progress in proceeding towards
clinical trials and its progress in ongoing clinical testing, the Committee's
assessment of the Company's efforts to consummate new corporate partnering
arrangements for product development and marketing, and the performance of the
Company's stock during the year. After considering these and other factors, the
Committee concluded that the Company made progress in proceeding toward these
goals in 1996 on which the Chief Executive Officer's compensation was based.
 
SUMMARY
 
     The members of the Compensation Committee of the Board of Directors believe
that the Company's compensation programs are successful in attracting and
retaining qualified employees and tying compensation directly to performance for
shareholders. We will continue to monitor closely the effectiveness and
appropriateness of each of the components of compensation to reflect changes in
the Company's business environment.

COMPLIANCE WITH SECTION 16(a) OF THE EXCHANGE ACT
 
     Section 16(a) of the Exchange Act requires the Company's executive officers
and directors and persons who own more than ten percent of a registered class of
the Company's equity securities to file reports of ownership and changes in
ownership with the Securities and Exchange Commission ("SEC") and the National
Association of Securities Dealers, Inc. Executive officers, directors and
greater than ten percent shareholders are required by SEC regulation to furnish
the Company with copies of all Section 16(a) forms they file. Based solely on
its review of the copies of such forms received by it, or on written
representations from certain reporting persons, the Company believes that,
during the fiscal year ended December 31, 1996, all filing requirements were
complied with applicable to its executive officers and directors.
