     Directors are elected by the Company's stockholders at each annual
meeting or, in the case of a vacancy, are appointed by the directors then in
office, to serve until the next annual meeting or until their successors are
elected and qualified.

     On March 31, 1998, the directors and all officers of the Company
beneficially owned in the aggregate 4,569,364 shares of the Company's Common
Stock, including 2,973,932 shares subject to the exercise of stock options
exercisable or becoming exercisable within 60 days.  This aggregate ownership
represents approximately 10.8% of the total outstanding shares, including
shares deemed to be beneficially owned.  See "Principal Stockholders."

BOARD MEETINGS AND COMMITTEES

     During the year ended December 31, 1997, the Board of Directors held six
meetings.  All directors participated in at least 75% of the meetings of the
Board of Directors and the committees of the Board of Directors on which they
served, except for Dr. Wilensky who attended 73% of such meetings.  The
committees of the Board of Directors include the Audit Committee, the
Compensation and Stock Option Committee (the "Compensation Committee") and the
Nominating and Corporate Governance Committee.

     The Audit Committee recommends the appointment of the independent
auditors for the Company, reviews and approves the scope of the annual audit
undertaken by the independent auditors and reviews the independence of the
accounting firm.  The Audit Committee also reviews the audit and non-audit
fees of the independent auditors and the adequacy of the Company's internal
control procedures.  The Audit Committee met four times during the year ended
December 31, 1997.  The current members of the Audit Committee are Jack L.
Heckel (Chairman), Ronald L. Nelson and Dr. Gail R. Wilensky.

     The Compensation Committee reviews and recommends to the Board of
Directors remuneration arrangements for the Company's officers and key
employees and reviews and recommends compensation plans. In addition, the
Compensation Committee administers the Company's 1997 Stock Incentive Plan
(the "1997 Plan") and determines the key employees to be granted options under
such plan and the number of shares to be granted.  The Compensation Committee
also determines the individuals and other entities to be granted warrants
which are issued other than pursuant to the Company's stock option plan,
including the number of shares, and the terms and conditions with respect to
which such warrants are granted.  The Compensation Committee met four times
during the year ended December 31, 1997.  The current members of the
Compensation Committee are David S. Tappan, Jr. (Chairman), Jack L. Heckel and
Dayton Ogden.

     The Nominating and Corporate Governance Committee's primary function is
to assist the Board of Directors in identifying and recommending candidates
with the appropriate qualifications and experience to serve on the Company's
Board of Directors.  In addition, the Nominating and Corporate Governance
Committee reviews and, as appropriate, makes recommendations with respect to
such topics as corporate governance and performance of the Board of Directors.
During 1997, meetings of the Nominating and Corporate Governance Committee
were held as part of the Board of Directors' regular quarterly meetings.  The
full Board of Directors serves on the Nominating and Corporate Governance
Committee with Dayton Ogden as Chairman.

Director Compensation.  Each member of the Board of Directors who is not an
- ----------------------
officer or employee of the Company receives travel and expense reimbursement
and $1,000 in connection with attending regular or special (except for
telephonic) meetings of the Board of Directors or Compensation, Audit or
Nominating and Corporate Governance Committees of the Board of Directors.  Dr.
Groopman also receives $20,000 annually in connection with services rendered
to the Company as Chairman of the Scientific Advisory Board.  In addition,
under the 1997 Plan, each non-employee member of the Board of Directors is
automatically granted a non-statutory stock option to purchase 50,000 shares
of Common Stock at an exercise price equal to 100% of the market price of the
Common Stock at the time of initial election or appointment to the Board of
Directors.  The options are immediately exercisable for all the option shares,
but any purchased shares will be subject to repurchase by the Company, at the
exercise price paid per share, upon the non-employee director's cessation of
Board service prior to vesting in those shares.  The shares subject to the
option become vested and the Company's repurchase rights lapse 

                                   4
<PAGE>


in three successive equal annual installments measured from the grant date.  
Under the 1997 Plan, each non-employee director will receive an additional 
50,000 share option grant upon re-election to the Board of Directors at each 
Annual Meeting of Stockholders in the year during which the final installment 
of his or her last previous grant vests.  Upon his election to the Board of 
Directors in 1997, Mr. Nelson received such an automatic 50,000 share option 
grant.  These options are exercisable at $11.31 per share and will vest in 
annual equal installments over three years.

     Section 16(a) of the Securities Exchange Act of 1934 requires directors

registered class of the Company's equity securities ("Reporting Persons") to
file with the Securities and Exchange Commission (the "SEC") reports on Forms
3, 4 and 5 of initial ownership and of changes in beneficial ownership of
Common Stock.  Based solely on the Company's review of the reporting forms
received by it, and written representations from certain persons that no 
Form 5 reports were required to be filed by those persons, the Company 
believes that all statements of beneficial ownership required to be filed 
with the SEC in fiscal 1997 were timely filed.

Employment Agreements/Change in Control Arrangements.  The Company has no
- -----------------------------------------------------
employment agreements with any of the Named Executive Officers or any of its
other employees.  In the event the Company is acquired by merger,
consolidation or asset sale, outstanding options which are not assumed by the
successor corporation, or replaced with a comparable option to purchase shares
of the capital stock of the successor corporation, are to be automatically
accelerated in full, except to the extent such acceleration is otherwise
limited by the terms of the instrument evidencing such grant.  The
Compensation Committee or the full Board of Directors has the discretionary
authority, exercisable either in advance or at the time of certain hostile
changes in control of the Company (whether effected through a tender offer for
outstanding shares of the Company's outstanding stock or a proxy contest for
Board of Directors membership), to provide for the automatic acceleration of
one or more such option grants outstanding at the time of such a hostile
change in control.  They also have the authority to condition any such option
acceleration upon the subsequent termination of the optionee's service within
a specified period following the change in control.  All outstanding options
held by the executive officers are either fully exercisable or provide for
automatic acceleration upon the involuntary termination of the officers'
employment following an acquisition of the Company by merger or asset sale or
upon a hostile change of control.

Compensation Committee Interlocks and Insider Participation.  No member of the
- ------------------------------------------------------------
Compensation Committee is a former or current officer or employee of the
Company.  See "Directors and Nominees" and "Board Meetings and Committees" for
a discussion of the Compensation Committee members' background and
relationship to the Company.  No officers of the Company serve or have ever
served on compensation committees of entities at which Board members serve or
have served as officers.

COMPENSATION COMMITTEE REPORT

     The report set forth below has been provided by the Compensation
Committee and describes the philosophy and process considered by the
Compensation Committee in administering the Company's executive compensation
program.

- ------------------------------------------------------------------------------
COMPENSATION COMMITTEE REPORT*
- ------------------------------------------------------------------------------
     The Company's executive compensation program is administered by the
Compensation and Stock Option Committee.  The executive compensation program
is structured and administered to support the Company's mission, strategy and
values.

Compensation Philosophy

     The Company's executive compensation program has been designed to enable
the Company to attract, motivate and retain senior management by providing
what the Company believes is a competitive total compensation package based on
performance.  The executive compensation program is composed of three
principal elements:  (1) competitive base salaries which reflect individual
performance, (2) annual performance-based incentive opportunities which are
variable and payable in cash for the achievement of corporate goals (as
discussed below under "Compensation of the Chief Executive Officer") approved
by the Compensation Committee and individual goals established in consultation
with the Chief Executive Officer, and (3) long-term stock-based incentive
opportunities pursuant to a stock option plan geared to strengthen the
mutuality of interests between senior management and the Company's
stockholders.

     As an executive officer's level of responsibility increases, a greater
portion of his or her potential total compensation opportunity is based on
performance incentives, causing greater variability in the individual's
absolute compensation level from year to year.  In addition, the higher that
one rises in the organization, the greater the mix of compensation shifts to
reliance on the value of the Company's Common Stock through stock-based
awards.

     As a result of Section 162(m) of the Internal Revenue Code, which was
enacted into law in 1993, the Company will not be allowed a federal income tax
deduction for compensation paid to certain executive 

                                   11
<PAGE>


officers, to the extent that compensation exceeds $1 million per officer in 
any one year.  This limitation does not apply to compensation paid to the Named 
Executive Officers which qualifies as performance-based compensation.  The 
Compensation Committee has not and does not intend to set compensation levels 
which would exceed the $1 million limit in 1998.  Any compensation deemed 
paid in connection with the exercise of options granted under the Company's 
1997 Stock Incentive Plan (the '1997 Plan") will qualify as performance-based 
compensation.

The Compensation Process

     Early in each fiscal year, the Compensation Committee reviews with the
Chief Executive Officer and the Vice President, Human Resources, an annual
salary plan for the Company's executive officers.  This salary plan is based
on industry, peer group and national surveys conducted by a
nationally-recognized compensation consulting firm which specializes in the
biotechnology/biomedical industries, and performance evaluation based upon
past and expected future contributions of the individual executive officers.
In particular, the Compensation Committee obtains and reviews comparative
total compensation figures from (i) a group of approximately 60 diverse public
companies in the biomedical/biotechnology industries with greater than 150 but
less than 500 employees, (ii) a select group of approximately 44 companies
which are considered leaders in the biotechnology industry by virtue of their
market capitalization, and (iii) a select group of public biotechnology
companies at a similar stage of development.

     Base salary levels for each of the Company's executive officers, with the
exception of the Chief Executive Officer, are established annually within
ranges determined by analysis of comparative compensation.  The mid-point of
such ranges is designed to be comparable to the 50th percentile of survey data
obtained as set forth above.  Under the Company's bonus program, each
executive officer may earn an annual targeted cash incentive which is
calculated as a percentage of such officer's base salary, 50% of which is
based on the accomplishment of corporate goals (which are the same as those
discussed below for the Chief Executive Officer) and 50% on the achievement of
individual goals set at the beginning of each year.  Such targeted cash
incentive amounts range from approximately 27% to approximately 37% depending
on the level of the executive officer.

     Long-term incentive compensation is provided through stock options which
are granted to executive officers of the Company upon hire.  The amount of
stock options granted is a function of position and level of responsibility,
and options become exercisable in equal annual installments over a five-year
period.  The Compensation Committee, in its discretion, may grant additional
options to executive officers, including the Chief Executive Officer, for
increases in level of responsibility and promotions, in recognition of
sustained exceptional performance or annually based upon company and
individual performance.

     Each year, the Compensation Committee has retained an outside,
independent compensation consulting firm, which specializes in the
biotechnology/biomedical industries, to review and evaluate the Company's
process of establishing, reviewing and adjusting the compensation of the
Company's executive officers.  After its most recent review, conducted in
March 1998, such consulting firm concluded that the process presently employed
by the Company in obtaining, analyzing and employing comparative data, and
implementing the Company's compensation programs for the Company's executive
officers and for the Chief Executive Officer, is consistent with industry
norms and appropriate and reasonable under the circumstances.

Compensation of the Chief Executive Officer

     The Compensation Committee annually reviews and fixes the base salary of
the Chief Executive Officer based in part on the competitive compensation data
discussed above, and the Compensation Committee's assessment of his past
performance and its expectation as to his future contributions in leading the
Company and its development.  As the Company has only during the past year
introduced its first therapeutic products, profitability of the Company has
not been considered in setting the Chief Executive Officer's compensation;

                                  12
<PAGE>


however, the Committee does consider a number of financial factors, including
the Company's ability to secure financing, expense reduction and control, and
the efficient use of working capital to achieve corporate goals.  In
determining the Chief Executive Officer's base salary for each year, the
Committee also considers significant accomplishments made by the Company
during the prior year and other performance factors, such as the effectiveness
of the Chief Executive Officer in establishing the Company's strategic
direction.  The annual cash bonus paid to the Chief Executive Officer, if any,
is entirely dependent on the accomplishment by the Company of certain
corporate goals established by management and approved by the Board of
Directors near the commencement of each fiscal year.  Factors considered by
the Compensation Committee in determining the Chief Executive Officer's annual
base salary and bonus, if any, are not subject to any specific weighting or
formula.

     In determining the Chief Executive Officer's base salary for 1997 as
reported in the cash compensation table, the Compensation Committee considered
1996 accomplishments as well as the comparative competitive compensation data
and performance factors discussed above.  The major accomplishments of the
Company in 1996 which the Committee considered included: (i) the
recommendation for approval of Dermagraft-TC(R), the Company's first 
therapeutic product, by an independent advisory committee convened by the 
U.S. Food and Drug Administration (the "FDA"); (ii) successful inspection of 
the Company's manufacturing facility for Dermagraft-TC, which is required for 
marketing approval; (iii) submission of a Premarket Approval ("PMA") 
application for Dermagraft in the treatment of diabetic foot ulcers under the 
FDA's expedited review process; (iv) submission of an Investigational Device 
Exemption ("IDE") for a pilot clinical trial of tissue engineered articular 
cartilage; (v) entering into agreement for a fifty-fifty joint venture with 
a worldwide leader in wound care for the global commercialization of 
Dermagraft in the treatment of diabetic foot ulcers; and (vi) obtaining 
financing.

     In determining the Chief Executive Officer's bonus eligibility for 1997,
the Committee considered the Chief Executive Officer's role in the Company's
achievement of corporate objectives, however, payment of 1997 bonuses for the
Chief Executive Officer and other executive officers has been deferred until 
such time as the Company's manufacturing facility for Dermagraft is approved 
by the FDA.  The corporate objectives considered by the Committee in 
determining the Chief Executive Officer's 1997 bonus were as follows: (i) the
approval and launch of Dermagraft-TC by the FDA for full-thickness burns; 
(ii) filing and approval for the use of Dermagraft-TC in partial-thickness 
burns (iii) completing the expansion and validation of the manufacturing 
facility to support the launch of Dermagraft; (iv) approval and launch of 
Dermagraft for treatment of diabetic foot ulcers in Canada and the United 
Kingdom, respectively; (v) establishing systems and processes to support the 
ongoing commercialization of products; (vi) advancing the development of 
tissue engineered cartilage and cardiovascular products; (vii) progress in 
developing and managing strategic relationships; and (viii) obtaining 
financing.

CERTAIN TRANSACTIONS

     The Company has entered into indemnification agreements with each of its
directors and officers which provide such individuals with indemnification
rights, which are in addition to those provided by the Company's Bylaws.  One
significant difference between the indemnification rights provided under the
Company's Bylaws and those provided under the indemnification agreements is
that, under the Bylaws determinations are made on a case-by-case basis that
the individual claiming indemnity meets certain specified standards of
conduct.  Under the indemnification agreements, a determination that a
director or officer has met these standards is not required for such
indemnity, although the agreements exclude indemnity for conduct which is
adjudged to be knowingly fraudulent, deliberately dishonest or to constitute
willful misconduct.  The Company also currently maintains policies of
insurance under which its directors and officers are insured, within the
limits and subject to the limitations of the policies, against certain
expenses in connection with the defense of actions, suits or proceedings, and
certain liabilities which might be imposed as a result of such actions, suits
or proceedings, to which they are parties by reason of being or having been
such directors or officers.

     On March 31, 1998, Arthur J. Benvenuto, Chairman of the Board and Chief
Executive Officer, and Dr. Gail K. Naughton, President and Chief Operating
Officer, were indebted to the Company in the amount of $1,110,058 (including
$191,558 representing accrued interest) and $413,005 (including $63,005
representing accrued interest), respectively.  Mr. Benvenuto's loan was for
the exercise of an employee stock option and is 

                                  14
<PAGE>


evidenced by a promissory note bearing interest at the rate of 6.75% per 
annum with principal and interest due in May 1999.  Dr. Naughton's loan 
bears interest at the rate of 6.75% per annum and is due in July 1999.  Each 
loan is secured by shares of Common Stock of the Company and becomes due and 
payable within 180 days of termination (other than due to death or 
disability).  In addition, Mr. Benvenuto and Dr. Naughton must each use the 
proceeds from the sale of shares of the Company's Common Stock securing such 
loans to repay amounts owing under his or her loan.


                                  PROPOSAL 2
                             SELECTION OF AUDITORS
