    The specific proposals to be considered and acted upon at the Annual Meeting
are summarized in the accompanying Notice and are described in more detail in
this Proxy Statement. Stockholders of record at the close of business on March
16, 1998 are entitled to notice of, and to vote at, the Annual Meeting. As of
the close of business on such date, there were 3,387,751 shares of the Company's
common stock, par value $0.001 per share (the "Common Stock"), outstanding and

of the Company's Series A Convertible Preferred Stock, par value $0.001 per
share (the "Series A Preferred"), outstanding and entitled to vote, and held by
211 stockholders of record. Each holder of Common Stock is entitled to one vote

Common Stock into which such holder's Series A Preferred was convertible as of
the record date. As of the record date, each share of Series A Preferred was
convertible into 2.12 shares of Common Stock and, therefore, the class of Series
A Preferred is entitled to an aggregate of 2,253,191 votes. Stockholders may not
cumulate votes in the election of directors.
 
    If a choice as to the matters coming before the Annual Meeting has been
specified by a stockholder on the Proxy, the shares will be voted accordingly.

broker or nominee specifically indicating the lack of discretionary authority to
vote on the matter) are counted for purposes of determining the presence or
absence of a quorum for the transaction of business. Abstentions will be counted
towards the tabulation of votes cast on proposals presented to the stockholders
and will have the
 
                                       1

same effect as negative votes, whereas broker non-votes will not be counted for
purposes of determining whether a proposal has been approved or not.

                 MATTERS TO BE CONSIDERED AT THE ANNUAL MEETING
                      PROPOSAL ONE--ELECTION OF DIRECTORS
 
    At the Annual Meeting, a Board of six directors will be elected to serve for
one year and until their successors shall have been duly elected and qualified
or until their earlier resignation or removal. The Board has selected six
nominees, all of whom are current directors of the Company. Each person
nominated for election has agreed to serve if elected, and management has no
reason to believe that any nominee will be unavailable to serve. Unless
otherwise instructed, the Proxy holders will vote the Proxies received by them
IN FAVOR OF the nominees named below. The six candidates receiving the highest
number of affirmative votes of the shares entitled to vote at the Annual Meeting
will be elected. The holders of Common Stock and Series A Preferred vote
together as a class for the election of directors. If any nominee is unable to
or declines to serve as a director, the Proxies may be voted for a substitute
nominee designated by the current Board. As of the date of this Proxy Statement,
the Board is not aware of any nominee who is unable or will decline to serve as
a director.
 
    THE BOARD RECOMMENDS THAT THE STOCKHOLDERS VOTE IN FAVOR OF THE ELECTION OF
EACH OF THE FOLLOWING NOMINEES TO SERVE AS DIRECTORS OF THE COMPANY UNTIL THE
NEXT ANNUAL MEETING OF STOCKHOLDERS AND UNTIL THEIR SUCCESSORS HAVE BEEN DULY

NUMBER OF DIRECTORS; RELATIONSHIPS
 
    The Company's Bylaws authorize the Board to fix by resolution the number of
directors serving on the Board, provided that such number is one or more. Since
March 13, 1998, the number of directors has been fixed at six. All directors
hold office until the annual meeting of stockholders following the initial
election
 
                                       4

or appointment of such director and until their successors have been duly
elected and qualified, or until their earlier resignation or removal. Officers
are appointed to serve at the discretion of the Board.
 
    There are no family relationships among the executive officers or directors
of the Company.
 
BOARD MEETINGS AND COMMITTEES
 
    The Board held five meetings and acted once by unanimous written consent
during the 1997 fiscal year. Each of the directors participated in or attended
at least 75% of the aggregate number of meetings held during the period that
such director was a member of the Board, except that Mr. Kanzer attended two
meetings of the Board during the 1997 fiscal year.
 
    The Board has an Audit Committee and a Compensation Committee, but not a
standing Nominating Committee. The Audit Committee, which is composed of Mr.
Kanzer and Dr. Prendergast, reviews the professional services provided by the
Company's independent auditors and monitors the scope and results of the annual
audit; reviews proposed changes in the Company's financial and accounting
standards and principles; reviews the Company's policies and procedures with
respect to its internal accounting, auditing and financial controls; makes
recommendations to the Board on the engagement of the independent auditors and
addresses other matters that may come before it or as directed by the Board of
Directors. The Audit Committee did not hold any meetings during the 1997 fiscal
year.
 
    The Compensation Committee, which is composed of Mr. Kanzer, Dr. Fildes and
Dr. Prendergast, sets the compensation for certain of the Company's personnel
and administers the Company's 1995 Stock Option Plan, as amended and restated
(the "1995 Stock Option Plan"). The Compensation Committee acted once by
unanimous written consent during the 1997 fiscal year.

Stock, at an exercise price of $6.8125 per share, the fair market value of the

                           PROPOSAL TWO--APPROVAL OF
                           AMENDMENT TO THE COMPANY'S
                     RESTATED CERTIFICATE OF INCORPORATION
 
INTRODUCTION
 
    On March 13, 1998, the Board of Directors adopted, subject to stockholder
approval, a proposed amendment of the Company's Restated Certificate of
Incorporation, as amended (the "Certificate"), to decrease the number of
authorized shares of the Common Stock from 80,000,000 to 50,000,000 and the
number of authorized shares of Preferred Stock, par value $0.001 per share (the
"Preferred Stock"), from 50,000,000 to 10,000,000. The Board recommends to the
stockholders the proposed amendment of the Certificate to decrease the number of
authorized shares of Common Stock and Preferred Stock because the Board believes
that (1) the reduced number of authorized shares is sufficient to meet the needs
of the Company for at least the next three to five years and (2) reducing the
number of authorized shares will result in a decrease in the Company's corporate
franchise tax liability to the State of Delaware.
 
    As of the close of business on March 16, 1998, there were 3,387,751 shares
of the Company's Common Stock outstanding and an aggregate of 7,352,011 shares
of Common Stock reserved for issuance pursuant to the 1995 Stock Option Plan,
upon the exercise of outstanding warrants, upon the conversion of the
outstanding shares of Series A Preferred and upon the exercise (and subsequent
conversion into shares of Common Stock) of outstanding warrants exercisable for
Series A Preferred. Accordingly, based on the number of fully-diluted shares of
Common Stock as of the close of business on March 16, 1998, the Company would
have remaining 39,260,238 shares of Common Stock to issue if the Certificate
were amended to decrease to 50,000,000 the number of authorized shares of Common
Stock. The Company believes that such number of shares of Common Stock is
sufficient to meet the needs of the Company for at least the next three to five
years.
 
    As of the close of business on March 16, 1998, 1,375,000 shares of the
Preferred Stock had been designated as Series A Preferred. Accordingly, based on
the number of shares of Preferred Stock designated as of the close of business
on March 16, 1998, the Company would have remaining 8,625,000 shares of
Preferred Stock to issue if the Certificate were amended to decrease to
10,000,000 the number of authorized shares of Preferred Stock. The Company
believes that such number of shares of Preferred Stock is sufficient to meet the
needs of the Company for at least the next three to five years.
 
    In addition, the proposed amendment will reduce the Company's corporate
franchise tax liability to the State of Delaware. Delaware's corporate franchise
tax is based, in part, on the number of shares of stock authorized in a
corporation's certificate of incorporation. As a result of reducing, by
approximately 50%, the number of shares authorized in the Company's Certificate,
the Company annually will save approximately 50% of the corporate franchise
taxes that it would otherwise be obligated to pay to the State of Delaware. If
the proposed amendment had been effective at the beginning of fiscal year 1997,
the Company would have saved approximately $25,000 in corporate franchise taxes
payable to the State of Delaware for fiscal year 1997.
 
    It is expected that the proposed amendment of the Certificate, if approved
by the stockholders, will be made effective on or about May 11, 1998 by the
filing and recording of an appropriate Certificate of Amendment as required
under Delaware law.
 
STOCKHOLDER APPROVAL
 
    The affirmative vote of the holders of a majority of the outstanding shares
of Common Stock and Series A Preferred, voting together as a class, present in
person or represented by Proxy at the Annual Meeting and entitled to vote on
this Proposal Two is required for approval of the amendment of the Certificate
to decrease the number of authorized shares of Common Stock and the number of
authorized shares of Preferred Stock.
 
                                       7

RECOMMENDATION OF THE BOARD OF DIRECTORS
 
    The Board of Directors recommends that the stockholders vote FOR the
approval of the amendment of the Certificate as described in this Proposal Two.
The Board believes that approval of the amendment of the Certificate is in the
best interests of the Company because (1) the reduced number of authorized
shares should be sufficient to meet the needs of the Company for at least the
next three to five years and (2) reducing the number of authorized shares will
result in a decrease in the Company's corporate franchise tax liability to the
State of Delaware. ACCORDINGLY, THE BOARD RECOMMENDS THAT THE STOCKHOLDERS VOTE
IN FAVOR OF THE APPROVAL OF THE AMENDMENT OF THE CERTIFICATE TO REDUCE THE
NUMBER OF AUTHORIZED SHARES OF COMMON STOCK AND THE NUMBER OF AUTHORIZED SHARES
OF PREFERRED STOCK.
 
                                       8

                   PROPOSAL THREE--RATIFICATION OF SELECTION
                            OF INDEPENDENT AUDITORS
 
    The Board has appointed the firm of KPMG Peat Marwick LLP, independent
auditors, to audit the financial statements of the Company for the year ending
December 31, 1998 and is asking the stockholders to ratify this appointment.
 
    In the event the stockholders fail to ratify the appointment, the Board will
reconsider its selection. Even if the selection is ratified, the Board in its
discretion may direct the appointment of a different independent auditing firm
at any time during the year if the Board feels that such a change would be in
the best interests of the Company and its stockholders. The affirmative vote of
the holders of a majority of the shares of Common Stock and shares of Series A
Preferred, voting together as a class, present or represented by Proxy at the
Annual Meeting and entitled to vote is required to ratify the selection of KPMG
Peat Marwick LLP.
 
    KPMG Peat Marwick LLP commenced its annual audit of the Company's financial
statements in December 1995. A representative of KPMG Peat Marwick LLP is
expected to be present at the Annual Meeting to respond to appropriate questions
and will be given the opportunity to make a statement if he or she so desires.
 
RECOMMENDATION OF THE BOARD OF DIRECTORS
 
    THE BOARD RECOMMENDS THAT THE STOCKHOLDERS VOTE IN FAVOR OF THE RATIFICATION
OF THE SELECTION OF KPMG PEAT MARWICK LLP TO SERVE AS THE COMPANY'S INDEPENDENT
AUDITORS FOR THE YEAR ENDING DECEMBER 31, 1998.
 
                                       9

                           PROPOSAL FIVE--APPROVAL OF
                       NON-EMPLOYEE DIRECTOR COMPENSATION
 
    On October 24, 1997, the Board approved resolutions providing that as of
such date, in addition to any other compensation arrangements then in place,
each non-employee director of the Company shall be paid (a) $1,500 for each
regularly scheduled or special Board meeting attended in person, (b) $750 for
each regularly scheduled or special Board meeting attended by telephone and (c)
$500 for attendance at a meeting of a committee of the Board (whether attended
in person or by telephone) on which such director serves as a member. In
addition, each non-employee director is to receive an annual fee of $6,000,
payable bi-annually and pro-rated for any period of time that such director has
not served for a full six months.
 
    Pursuant to Section 6(b)(vii) of the Certificate of Designations of the
Series A Preferred as filed with the Secretary of State of the State of Delaware
on May 22, 1997, for so long as at least 50% of the shares of Series A Preferred
are outstanding, the affirmative vote of the holders of at least 66 2/3% of all
outstanding Series A Preferred voting separately as a class is necessary to
permit, effect or validate the Board's approval of any transaction between the
Company and its affiliates, including directors.
 
    Currently, Board members are reimbursed by the Company for reasonable
expenses incurred in connection with attendance of Board and committee meetings.
Directors who are also employees of the Company do not receive any additional
compensation for service on the Board. Currently, all directors are eligible to
receive payments under the proposal, except Mr. Lindjord, who is a Company
employee.
 
RECOMMENDATION OF THE BOARD OF DIRECTORS
 
    The Board recommends that the holders of Series A Preferred vote FOR the
approval of compensatory payments to non-employee directors, commencing as of
October 24, 1997, the date of Board approval. The Board believes that such
payments are in the best interest of the Company because, together with director
indemnification, they are essential for the Company to attract and retain highly
qualified individuals to contribute to the Company's financial success. Such
payments are common among the Company's competitors and competition for
qualified Board candidates is increasingly intense. CONSEQUENTLY, THE BOARD
RECOMMENDS THAT THE HOLDERS OF SERIES A PREFERRED VOTE IN FAVOR OF THE APPROVAL
OF PAYMENTS TO BE MADE BY THE COMPANY TO THE COMPANY'S NON-EMPLOYEE DIRECTORS AS
DESCRIBED ABOVE.

                     PROPOSAL SIX--APPROVAL OF CONSULTANCY
                AND FINANCIAL SERVICES AGREEMENTS WITH DR. IWAKI
 
    Subject to the approval of the holders of shares of the Company's Series A
Preferred, on March 13, 1998 the Board approved the Company's entering into each
of a Consultancy Agreement and a Financial Services Agreement with Yuichi Iwaki,
M.D., Ph.D. Dr. Iwaki and Dr. Prendergast abstained from such vote.
 
    Pursuant to Section 6(b)(vii) of the Certificate of Designations of the
Series A Preferred as filed with the Secretary of State of the State of Delaware
on May 22, 1997, for so long as at least 50% of the shares of Series A Preferred
are outstanding, the affirmative vote of the holders of at least 66 2/3% of all
outstanding Series A Preferred voting separately as a class is necessary to
permit, effect or validate the Board's approval of any transaction between the
Company and its affiliates, including directors.
 
    Dr. Iwaki is currently Director of the Transplantation Immunology and
Immunogenetics Laboratory in the Department of Urology at the University of
Southern California and a Professor of Urology and Pathology at the University
of Southern California School of Medicine. Under the terms of the Consultancy
Agreement, which shall have an initial term of three years, Dr. Iwaki will
commit to advise the Company, among other things, with respect to the direction
of its research and product development and business development activities. The
Company will pay to Dr. Iwaki $5,000 per month for such services, plus $1,000
per day spent traveling and/or performing services for the Company.
Additionally, the Company will issue to Dr. Iwaki a fully-vested option to
purchase up to 30,000 shares of Common Stock of the Company at an exercise price
of $6.8125 per share, the fair market value of such shares on March 13, 1998,
pursuant to the Company's 1995 Stock Option Plan. Such option will terminate on
March 12, 2005. In addition to providing consulting services, Dr. Iwaki will
agree not to employ or solicit any Company employee during the term of the
agreement and for a period of one year thereafter, and will assign to the
Company ownership of any intellectual property arising from his consulting
activities. The Consultancy Agreement will be terminable by either party upon 30
days' notice, and will supersede an earlier agreement pursuant to which the
Company paid Dr. Iwaki $2,500 per month.
 
    Under the Financial Services Agreement, Dr. Iwaki will undertake for an
initial period of three years to initiate and pursue contacts in the Japanese
financial and scientific communities with respect to obtaining an equity
investment in the Company or forming a collaborative scientific or business
relationship, in each case with a specific group of potential parties approved
by the Company. If the Company enters into such a transaction within one year
following Dr. Iwaki's introduction to such investor or collaborator, then the
Company shall pay to Dr. Iwaki a fee equal to 5% of the proceeds of such
transaction or transactions. To the extent the transaction involves the issuance
of Company securities, Dr. Iwaki may elect to receive a warrant from the Company
for an amount of securities equal to 5% of those issued in the transaction, less
the amount of any cash fee paid to Dr. Iwaki by the Company. Any such warrant
shall be exercisable for a period of five years at an exercise price equal to
the par value of the underlying securities, and shall have a cashless exercise
feature. The Company will also reimburse Dr. Iwaki's reasonable costs and
expenses incurred in connection with his activities thereunder. The Financial
Services Agreement will be terminable by either party upon 30 days' notice.
 
RECOMMENDATION OF THE BOARD OF DIRECTORS
 
    The Board believes that Dr. Iwaki would continue to provide an invaluable
service to the Company as both a scientific consultant and a financial advisor.
Dr. Iwaki is eminent in his field and enjoys a particularly strong reputation
among the Japanese scientific community, towards which his efforts will be
directed in connection with the Financial Advisory Agreement. If however, Dr.
Iwaki is unsuccessful in finding an investor or collaborator, the Company will
not be committed to paying any contingent fee. CONSEQUENTLY, THE BOARD
RECOMMENDS THAT THE HOLDERS OF SHARES OF SERIES A PREFERRED VOTE IN FAVOR OF THE
PROPOSED AGREEMENTS WITH DR. IWAKI.

                    PROPOSAL SEVEN--APPROVAL OF CONSULTANCY
             AND FINANCIAL SERVICES AGREEMENTS WITH DR. PRENDERGAST
 
    Subject to the approval of the holders of shares of the Company's Series A
Preferred, on March 13, 1998 the Board approved the Company's entering into each
of a Consultancy Agreement and a Financial Services Agreement with John K.A.
Prendergast, Ph.D. Dr. Iwaki and Dr. Prendergast abstained from such vote.
 
    Pursuant to Section 6(b)(vii) of the Certificate of Designations of the
Series A Preferred as filed with the Secretary of State of the State of Delaware
on May 22, 1997, for so long as at least 50% of the shares of Series A Preferred
are outstanding, the affirmative vote of the holders of at least 66 2/3% of all
outstanding Series A Preferred voting separately as a class is necessary to
permit, effect or validate the Board's approval of any transaction between the
Company and its affiliates, including directors.
 
    Dr. Prendergast co-founded the Company and two of its subsidiaries, and has
recently begun work as an independent business consultant to the pharmaceutical
industry after more than six years as a Managing Director of Paramount
Investments. Under the terms of the Consultancy Agreement, which shall have an
initial term of three years, Dr. Prendergast will commit to advise the Company
regarding, among other things, its business development activities. The Company
will pay to Dr. Prendergast $5,000 per month for such services, plus $1,000 per
day spent traveling and/or performing services for the Company. Additionally,
the Company will issue to Dr. Prendergast a fully-vested option to purchase up
to 30,000 shares of Common Stock of the Company at an exercise price of $6.8125
per share, the fair market value of such shares on March 13, 1998, pursuant to
the Company's 1995 Stock Option Plan. Such option will terminate on March 12,
2005. In addition to providing consulting services, Dr. Prendergast will agree
not to employ or solicit any Company employee during the term of the agreement
and for a period of one year thereafter, and will assign to the Company
ownership to any intellectual property arising from his consulting activities.
The Consultancy Agreement will be terminable by either party upon 30 days'
notice, and will supersede an earlier agreement between the Company and
Summercloud Bay, Inc., a corporation wholly owned by Dr. Prendergast, pursuant
to which the Company paid Summercloud Bay a consulting fee of $2,500 per month
and had issued a warrant exercisable for 37,500 shares of the Company's Common
Stock at an exercise price of $5.33 per share.
 
    Under the Financial Services Agreement, Dr. Prendergast will undertake for
an initial period of three years to initiate and pursue contacts in the
financial and scientific communities with respect to obtaining an equity
investment in the Company or forming a collaborative scientific or business
relationship, in each case with a specific group of potential parties approved
by the Company. If the Company enters into such a transaction within one year
following Dr. Prendergast's introduction to such investor or collaborator, then
the Company shall pay to Dr. Prendergast a fee equal to 5% of the proceeds of
such transaction or transactions, payable in cash or warrant, at the Company's
election. To the extent the transaction involves the issuance of Company
securities, Dr. Prendergast may elect to receive a warrant from the Company for
an amount of securities equal to 5% of those issued in the transaction, less the
amount of any cash fee paid to Dr. Prendergast by the Company. Any such warrant
shall be exercisable for a period of five years at an exercise price equal to
the par value of the underlying securities, and shall have a cashless exercise
feature. The Company will also reimburse Dr. Prendergast's reasonable costs and
expenses incurred in connection with his activities thereunder. The Financial
Services Agreement may be terminated by either party upon 30 days' notice.
 
RECOMMENDATION OF THE BOARD OF DIRECTORS
 
    Because of Dr. Prendergast's years of experience in both the
biopharmaceutical and the financial and investment banking communities, the
Board believes that Dr. Prendergast would continue to provide an invaluable
service to the Company as both a scientific consultant and a financial advisor.
If however, Dr. Prendergast is unsuccessful in finding an investor or
collaborator, the Company will not be committed
 
                                       12

to paying any contingent fee. CONSEQUENTLY, THE BOARD RECOMMENDS THAT THE
HOLDERS OF SHARES OF SERIES A PREFERRED VOTE IN FAVOR OF THE PROPOSED AGREEMENTS
WITH DR. PRENDERGAST.

(1) Each option has a maximum term of seven years, subject to earlier
    termination in the event of the optionee's cessation of service with the
    Company. The grant date for each of the options is January 15, 1997. Each
    option becomes exercisable in four equal annual installments upon completion
    of each year of service measured from the grant date. Each option will
    become immediately exercisable in full upon an acquisition of the Company by
    merger or asset sale, unless the option is assumed by the successor entity.
    Each option includes a limited stock appreciation right pursuant to which
    the optionee may surrender the option, to the extent exercisable for vested
    shares, upon the successful completion of a hostile tender for securities
    possessing more than 50% of the combined voting power of the Company's
    outstanding voting securities. In return for the surrendered option, the
    optionee will receive a cash distribution per surrendered option share equal
    to the excess of (i) the highest price paid per share of the Company's
    Common Stock in such hostile tender offer over (ii) the exercise price
    payable per share under the cancelled option.
 
(2) Calculated based on total option grants to employees of 115,000 shares of
    Common Stock during the 1997 fiscal year.
 
(3) The exercise price may be paid in cash or in shares of Common Stock (valued
    at fair market value on the exercise date) or through a cashless exercise
    procedure involving a same-day sale of the purchased shares. The Company may
    also finance the option exercise by loaning the optionee sufficient funds to
    pay the exercise price for the purchased shares and the federal and state
    income tax liability incurred by the optionee in connection with such
    exercise. The optionee may be permitted, subject to the approval of the Plan
    Administrator, to apply a portion of the shares purchased under the option
    (or to deliver existing shares of Common Stock) in satisfaction of such tax
    liability.

CHANGE OF CONTROL TRANSACTIONS
 
    The Company is not aware of any transactions resulting in a change of
control during fiscal year 1997.
 
CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
    The Company's Restated Certificate of Incorporation and Bylaws provide for
indemnification of directors, officers and other agents of the Company. At the
1997 Annual Meeting of the Stockholders of the Company, the stockholders
approved the Company entering into an indemnification agreement with each of its
directors and executive officers. Accordingly, the Company has entered into an
indemnification agreement with each of its directors and executive officers.
 
    Prior to a private financing consummated in September 1995, the Company's
operations had been financed primarily through loans provided by Lindsay A.
Rosenwald, M.D., a principal stockholder and former director of the Company, and
VentureTek, L.P. ("VentureTek"), a principal stockholder of the Company. The
principal amount of such loans that had been advanced during the period from
July 25, 1993 to June 30, 1995 together with the interest thereon through June
30, 1995, was $1,085,027 to Dr. Rosenwald and $1,357,277 to VentureTek, L.P.
(such indebtedness, including accrued interest through June 30, 1995, is
collectively referred to as the "Stockholder Loans"). On December 31, 1995,
Stockholder Loans aggregating $2,442,304 in principal and interest were
converted into an aggregate of 785,234 shares of the Company's Common Stock.
 
    In addition to the Stockholder Loans, VentureTek provided a loan to the
Company in July 1995 in an aggregate principal amount of $125,000, bearing
interest at the rate of 10% annually. This loan, together with $115,011 interest
accrued on such loan and on the Stockholder Loans (from July 1, 1995 until the
conversion thereof into shares of Common Stock), was repaid on January 15, 1996
from the proceeds of the Company's initial public offering.

    Joseph Stevens & Co., Inc. ("Joseph Stevens"), a principal stockholder of
the Company, was the underwriter in the Company's initial public offering. In
connection with the initial public offering, Joseph Stevens and the Company
entered into an Underwriting Agreement. In connection with a bridge financing
that occurred shortly before the initial public offering, Joseph Stevens acted
as placement agent and received fees and expenses totaling $195,000. In
addition, the Company granted Joseph Stevens, for nominal consideration, a
warrant (the "Joseph Stevens Warrant") exercisable for 165,000 units (each, a
"Unit"), the security issued by the Company in its initial public offering, each
Unit consisting of one share of Common Stock and a redeemable warrant
exercisable for one share of Common Stock. The Joseph Stevens Warrant is
exercisable until December 13, 2000 at an exercise price of $6.60 per Unit. In
addition, the Company and Joseph Stevens entered into a Financial Advisory and
Consulting Agreement and related Indemnity Agreement pursuant to which the
Company paid Joseph Stevens a monthly consulting fee of $2,000 (which obligation
terminated on December 18, 1997) and agreed to pay Joseph Stevens additional
consideration in the event Joseph Stevens assists the Company in connection with
certain financing or strategic transactions.
 
    On April 15, 1996 the Company entered into a letter agreement with
Paramount. Dr. Rosenwald is the President, Chairman and sole stockholder of
Paramount, and Paramount employs Mr. Kanzer, a director of the Company, and

agreement, Paramount agreed to render financial advisory services to the Company

designee to purchase 25,000 shares of the Company's Common Stock at an exercise
price of $10.00 per share and paying Paramount additional consideration in the

at an exercise price of $8.05 and (2) upon the consummation of a financing
transaction, the Company paid $76,438 to Paramount and issued a warrant to
Paramount's designee exercisable for 12,500 shares of the Company's Common Stock
at an exercise price of $6.73 per share. The term of the letter agreement has
expired.
 
    On June 24, 1996, the Company, Paramount and a second financial advisor
(Paramount and the second financial advisor are collectively referred to as the
"Financial Advisor") entered into a Financial Services Agreement pursuant to
which the Financial Advisor agreed to render financial advisory services.
Pursuant to the agreement, the Company paid the Financial Advisor a $30,000
retainer and agreed to pay additional consideration in the event the Financial
Advisor assisted the Company in connection with certain financing or strategic
transactions. The term of this Financial Services Agreement has expired,
although the Company may be obligated to pay fees to the Financial Advisor in
the event certain financing or strategic transactions are consummated pursuant
to the terms of the Financial Services Agreement.
 
    Effective February 26, 1997, the Company and Paramount entered into a letter
of intent whereby Paramount agreed to act as placement agent for the Company in
connection with the private placement of Series A Preferred (the "Private
Placement"). Thereafter, the Company entered into an agreement (the "Placement
Agreement") with Paramount, pursuant to which the Company agreed to pay
Paramount, for its services, compensation in the form of (i) cash commissions
equal to nine percent of the gross proceeds from the sale of the Series A
Preferred issued in the Private Placement and (ii) a non-accountable expense
allowance equal to four percent of the gross proceeds from the sale of the
Series A Preferred. In addition, upon the final closing date of the sale of the
Series A Preferred, the Company sold to Paramount and/or its designees, for
$0.001 per warrant, warrants exercisable for an aggregate of 123,720 shares of
Series A Preferred, at an exercise price of $11.00 per share of Series A
Preferred. Such warrants are exercisable for 10 years and contain certain
antidilution provisions. Under the Placement Agreement, the Company has agreed
to indemnify Paramount against certain liabilities, including liabilities under
the Securities Act.
 
                                       18

    In connection with the Private Placement, the Company and Paramount will
enter into an advisory agreement (the "Placement Advisory Agreement") pursuant
to which Paramount will act as the Company's non-exclusive financial advisor.
Such engagement will provide that Paramount receive (i) a monthly retainer of
$4,000 commencing June 1, 1997 (with a minimum engagement of 24 months), (ii)
out-of-pocket expenses incurred in connection with services performed under the
Placement Advisory Agreement and (iii) standard success fees in the event
Paramount assists the Company in connection with certain financing and strategic
transactions. Paramount has agreed that, in the event it is entitled to
compensation under the letter agreement dated April 15, 1996 or the Financial
Services Agreement dated June 24, 1996, each described above, and the Placement
Advisory Agreement, it will seek payment under only one of the agreements.
 
    All transactions between Atlantic and its officers, directors, principal
stockholders and their affiliates are approved by a majority of the Board of
Directors, including a majority of the independent and disinterested outside
directors on the Board of Directors. The Company believes that all of the
transactions set forth above were made on terms no less favorable to the Company
than could have been obtained from unaffiliated third parties.
 
                        COMPLIANCE WITH SECTION 16(A) OF
                      THE SECURITIES EXCHANGE ACT OF 1934
 
    Section 16(a) of the Securities Exchange Act of 1934, as amended, requires
the Company's officers, directors and persons who are the beneficial owners of
more than 10% of the Company's Common Stock to file initial reports of ownership
and reports of changes in ownership of the Common Stock with the Securities and
Exchange Commission (the "Commission"). Officers, directors and greater than 10%
stockholders are required by Commission regulations 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 furnished to the
Company and certain written representations that no other reports were required,
the Company believes that, during the period from January 1, 1997 to December
31, 1997, all officers, directors and beneficial owners of more than 10% of the
Company's Common Stock complied with all Section 16(a) requirements.
 
                      SECURITY OWNERSHIP OF MANAGEMENT AND
                           CERTAIN BENEFICIAL OWNERS
 
    The following table sets forth certain information known to the Company with
respect to the beneficial ownership of the Company's Common Stock as of March
16, 1998, by (i) all persons who are beneficial owners of five percent or more
of the Company's Common Stock, (ii) each director and nominee, (iii) the Named
Officers in the Summary Compensation Table above and (iv) all current directors
and executive officers as a group. The Company does not know of any person who
beneficially owns more than five percent of the Series A Preferred, and none of
the Company's directors or the Named Officers owns any shares of Series A
Preferred. The number of shares beneficially owned by each director or executive
officer is determined under rules of the Commission and the information is not
necessarily indicative of beneficial ownership for any other purpose. Shares of
the Company's Common Stock subject to convertible securities that are currently
exercisable or convertible or that will become exercisable or convertible within
60 days are deemed to be beneficially owned by the person holding such
convertible security for computing the percentage ownership of such person, but
are not treated as outstanding for computing the percentage of any other person.
Except as otherwise indicated, the Company believes that the beneficial owners
of the Company's Common Stock listed below, based upon such information
 
                                       19

furnished by such owners, have sole investment power with respect to such
shares, subject to community property laws where applicable.
