COMMITTEES  OF  THE  BOARD

     The  standing  Committees  of  the  Board  are  an  Audit  Committee  and a
Compensation  Committee. Messrs. Gray, de Havilland and Peter-Hoblyn are members
of  both  committees.  Mr.  Gray  is  Chairman of the Audit Committee and Mr. de

Havilland are independent directors. Mr. Peter-Hoblyn is an ex officio member of
these  committees  and as such does not vote or attend executive sessions of the
Committees.

     The  Audit  Committee  is  responsible  for  review  of  audits,  financial
reporting and compliance, and accounting and internal controls policy. For audit
services, the Audit Committee is responsible for the engagement and compensation
of  independent  auditors, oversight of their activities and evaluation of their
independence.  The  audit  committee  has  instituted  procedures  for receiving
reports  of improper recordkeeping, accounting or disclosure. The Board has also
constituted  the  Audit  Committee  as a Qualified Legal Compliance Committee in
accordance  with  Securities  and Exchange Commission regulations. A copy of the

proxy  statement.

     In  the  opinion  of  the  Board  each  of  the voting members of the Audit
Committee  has  both  business  experience  and  an  understanding  of generally
accepted  accounting  principles  and  financial  statements  enabling  them  to
effectively  discharge  their  responsibilities  as  members  of that Committee.
Moreover,  the  Board  has determined that Mr. Gray is a Financial Expert within
the  meaning  of Securities and Exchange Commission regulations.  In making this
determination  the  Board  considered  Mr.  Gray's  formal  training  and  long
experience  in  accounting and auditing and his former service for many years as
the  Chairman  of  the  Audit  Committee  of another reporting Company under the
Securities  Exchange  Act.

     The  Compensation  Committee  is  responsible  for  establishing  executive
compensation  and  administering  the  Company's  Incentive  Compensation  Plan.

MEETINGS

     During  2002  there  were  five  meetings  of the Board of Directors of the
Company,  one  meeting  of  the  Compensation Committee, and two meetings of the



Audit  Committee.  Each  director  of the Company attended at least 75% of Board
and  committee  meetings  of  which  he  was  a  member  during  2002.

INDEMNIFICATION

     Under  the  Certificate of Incorporation of the Company, indemnification is
afforded  the  Company's  directors and executive officers to the fullest extent
permitted  by  the  provisions  of  the  General Corporation Law of the State of
Delaware.  Such  indemnification  also  includes  payment  of any costs which an
indemnitee  incurs  because  of  claims  against the indemnitee. The Company is,
however,  not  obligated  to provide indemnity and costs where it is adjudicated
that  the indemnitee did not act in good faith in the reasonable belief that the
indemnitee's  actions were in the best interests of the Company, or, in the case
of a settlement of a claim, such determination is made by the Board of Directors
of  the  Company.

     The  Company  carries  insurance  providing  indemnification, under certain
circumstances,  to  all of its directors and officers for claims against them by
reason  of, among other things, any act or failure to act in their capacities as
directors  or  officers.  The annual premium for this policy is $82,500. No sums
have  been  paid  for  such  indemnification  to any past or present director or
officer  by  the  Company  or  under  any  insurance  policy.

                     RATIFICATION OF APPOINTMENT OF AUDITORS

     The  Audit  Committee  has  reappointed  the  firm  of  Ernst  & Young LLP,
Certified  Public Accountants ("Ernst & Young"), to be the Company's independent
auditors  for  the  year 2003 and submits that reappointment to stockholders for
ratification.  Ernst  &  Young  has  served  in  that  capacity  since  1994.  A
representative  of  Ernst  &  Young  is not expected to be present at the London
Meeting.

AUDIT  FEES

     In  2002, Ernst & Young accepted $62,000 for fees for professional services
for  the audit of the Company's 2002 financial statements and the reviews of the
Company's  financial  statements included in quarterly reports on Securities and
Exchange  Commission  Form  10-Q  filed  in  2002.

FINANCIAL  INFORMATION  SYSTEMS  DESIGN  AND  IMPLEMENTATION  FEES

     In  2002,  Ernst  & Young did not perform any professional services for the
Company  in  connection  with  financial  information  systems  design  and
implementation.
ALL  OTHER  FEES

     In  2002,  Ernst  &  Young performed no non-audit services for the Company.

     THE AFFIRMATIVE VOTE OF A MAJORITY OF THE SHARES VOTING IS REQUIRED FOR THE
APPROVAL  OF  THIS  PROPOSAL.  THE  COMPANY RECOMMENDS A VOTE FOR THIS PROPOSAL.

REPORT  OF  THE  AUDIT  COMMITTEE

     Management  is  responsible  for  the  Company's  internal controls and its
financial  reporting. The independent auditors are responsible for performing an
audit  of  the  Company's  financial  statements  in  accordance  with  auditing
standards  generally accepted in the United States and for expressing an opinion
on  those financial statements based on their audit. The Audit Committee reviews



these  processes.  In such context, the Committee has reviewed and discussed the
audited  financial  statements  contained in the 2002 Annual Report on Form 10-K
with  the  Company's  management  and  its  independent  auditors.

     The  Committee  has  discussed  with  the  independent auditors the matters
required  to  be  discussed  by  the  Statement  on  Auditing  Standards  No. 61
(Communication  with  Audit  Committees),  as  amended.

     The  Committee has received the written disclosures and the letter from the
independent  auditors  required  by  Independence Standards Board Standard No. 1
(Independence  Discussions with Audit Committees), as amended, and has discussed
with  the  independent  auditors  their  independence.  The  Committee  has also
considered  whether  the  provision  of  the  services described above under the
captions  "Financial  Information  Systems  Design  and Implementation" and "All
Other  Fees"  is compatible with maintaining the independence of the independent
auditors.

     Based  on  the  review  and  discussions  referred  to above. The Committee
recommended  to  the Board of Directors that the audited financial statements be
included in the Company's Annual Report on Form 10-K for the year ended December
31,  2002  filed  with  the  Securities  and  Exchange  Commission.

     This  report  has  been  provided  by  the  following  members of the Audit
Committee:  D.  R.  Gray,  Chairman  and  J.  A.  de  Havilland.

       REPORT OF THE BOARD OF DIRECTORS ON EXECUTIVE COMPENSATION POLICIES

     Compensation  for  executives  is based on the philosophy that compensation
must  (a)  be  competitive with other businesses to attract, motivate and retain
the  talent needed to lead and grow the Company's business, (b) be linked to the
Company's  needs  for strong entrepreneurial skills to commercialize and promote
its  products,  (c)  encourage executive officers to build their holdings of the
Company's  stock  to align their goals with those of the stockholders and (d) to
conserve  cash.

COMPENSATION  OF  EXECUTIVE  OFFICERS  -  2002

     The  key  components of the Company's executive compensation program during
the  last  fiscal  year  were  base salary and non qualified stock option awards
under  the  1994  Plan.  The  cash based portion of compensation is fixed by the
Board  in  its  discretion  based  upon  historical levels, performance, ranking
within  the  officer  group,  amounts being paid by comparable companies and the
Company's  financial  position. Stock options are designed to provide additional
incentives  to executive officers to maximize stockholder value. Through the use
of  vesting  periods  the  option program encourages executives to remain in the
employ  of the Company. In addition, because the exercise prices of such options
are  set  at  the  fair  market  value  of the stock on the date of grant of the
option,  executives  can only benefit from such options, if the trading price of
the  Company's  shares  increases,  thus aligning their financial interests with
those  of  the  stockholders. Finally, stock options minimize the Company's cash
compensation  requirements.

COMPENSATION  OF  CHIEF  EXECUTIVE  OFFICER  -  2002

     The  compensation of the Chief Executive Officer, Mr. Peter-Hoblyn, in 2002
was  made  up  of  base  salary and stock options. (See the Summary Compensation
Table  above.)  An  accrual  on  account  of an annuity to be purchased was also
provided.  The  amount  of base salary was fixed in 2002 in the overall business
judgment  of  the Board considering the proper competitive level of salary to be
paid  in  view  of  the  Company's  position  and  salaries  paid  by comparable
companies.  Also, in 2002 Mr. Peter-Hoblyn was awarded an incentive stock option
for 100,000 shares under the Plan in accordance with the Company's philosophy of
providing  to  management  incentives  aligned  with  the  interests  of  the
stockholders.

     Mr.  Peter-Hoblyn's  base  salary for 2002 was raised to $300,000 effective
March  15,  2002.

     This  report has been provided by the following members of the Compensation
Committee  of  the  Board  of  Directors of the Company: D. R. Gray and J. A. de
Havilland,  Chairman.
