RECENT DEVELOPMENTS

     On September 23, 2003, the Corporation completed the initial public
offering of its Common Shares in the United States and a new issue of Common
Shares in Canada. In connection with this offering, the Common Shares were
approved for quotation on the Nasdaq National Market ("NASDAQ") and trading
commenced on September 18, 2003, under the "NRMX" symbol. The Corporation
offered 5.75 million Common Shares at a price of US$10.87 per share. The
aggregate net proceeds from the offering were approximately US$59 million, net
of underwriting fees and commissions. The Corporation intends to use these
proceeds to fund clinical trials of its lead product candidates, as well as to
further complete pre-clinical and research and development



                                      -3-

programs. The Corporation also intends to use the proceeds for capital
expenditures and the balance for working capital and general corporate purposes.


ELECTION OF DIRECTORS

serve as a director, but, if that should occur for any reason at or prior to the
Meeting, the persons named in the enclosed form of proxy reserve the right to
vote for another nominee at their discretion, unless instructions have been
received from a particular shareholder to withhold its shares from voting with
respect to the election of directors. Each director elected will hold office
until the next annual meeting of shareholders or until his successor is duly
elected, unless his office is earlier vacated in accordance with the by-laws of
the Corporation. Except as indicated, all of the persons named in the table
below are now members of the Board of Directors of the Corporation (the "Board")

NOTES:

(1)  The value of unexercised in-the-money options at financial year-end is the
     difference between the exercise price and the closing sale price of the
     Common Shares on the Toronto Stock Exchange (the "TSX") on December 31,
     2003. This gain has not been, and may never be, realized. The options have
     not been, and may never be, exercised and actual gains, if any, on exercise
     will depend on the value of the Common Shares on the date of exercise. The
     closing sale price of the Common Shares on the TSX, on December 31, 2003
     was $30.60.

which has not been specifically allocated between directors as a group and
officers as a group, was paid entirely by the Corporation.

COMPOSITION OF THE COMPENSATION COMMITTEE

     The Compensation Committee of the Board currently consists of Dr. Colin
Bier (Chair), Mr. Peter Kruyt and Mr. Ronald M. Nordmann. During the most
recently completed year, Dr. Francesco Bellini, O.C., the Corporation's Chairman
and Chief Executive Officer also served on the Compensation Committee. Dr.

through a management services agreement dated March 1, 2003, as amended as of

REPORT ON EXECUTIVE COMPENSATION

     The Corporation's current compensation policy for its executive officers,
including the Named Executive Officers, emphasizes incentive-based compensation
over base salary. Through the granting of options to purchase Common Shares, the
executive officers of the Corporation, including the Named Executive Officers,
are provided with incentive to (a) advance the drug development programs of the
Corporation towards commercialization and (b) enhance the market value of the
Corporation's Common Shares. In order to establish base salary and bonus
compensation levels, the Corporation studies, among other things, the
competitive market environment.

     The members of the Compensation Committee, whose names are set out above,
have approved the issue of the foregoing report and its inclusion in this proxy
circular.

     The outstanding Common Shares began trading at the opening of business on
June 22, 2000, on the TSX (NRM).

REPORT ON CORPORATE GOVERNANCE

     In 1995, the Toronto Stock Exchange Committee on Corporate Governance in
Canada issued its final report, establishing guidelines for corporate governance
for Canadian corporations (the "Guidelines"). The Guidelines relate to a number
of significant governance issues, including the proper role of the board of
directors, its structure and composition and its relationship with shareholders
and management. The TSX has adopted as a listing requirement that disclosure be
made by a listed corporation of its corporate governance practices with
reference to the Guidelines. A complete description of the Corporation's
corporate governance practices, with specific references to each of the
Guidelines is attached hereto as Schedule A. The Nominating and Corporate
Governance Committee, currently composed of Mr. Ronald M. Nordmann (chair), Dr.
Frederick H. Lowy, Mr. Peter Kruyt and Dr. Emil Skamene, has reviewed the
disclosure set out in Schedule A.

     Throughout 2003, the Corporation has reviewed its corporate governance
practices, particularly, in connection with its offering in the United States
and concurrent listing of the Common Shares for quotation on the NASDAQ. While
the Corporation has always been materially in compliance with the Guidelines, in
light of the quotation of its Common Shares on NASDAQ and changes in the
regulatory framework in the United States, most notably with the implementation
of the Sarbanes-Oxley Act, the Board concluded that it is was in the best
interests of the Corporation and its shareholders to implement certain changes
to its corporate governance practices. In addition to the Audit Committee and
the Compensation Committee, the Corporation created a Nominating and Corporate
Governance Committee, and a Disclosure Committee (which committee is comprised
solely of executive officers of the Corporation). Moreover, the Corporation
adopted a formal mandate of the Board of Directors, a charter for each of its
committees, a Disclosure and Trading Policy, a Code of Ethics and a Hiring
Policy for its independent auditors (to avoid any impairment of the independence
of the Corporation's independent auditors).

     The Board continues to review corporate governance proposals made by the
Toronto Stock Exchange, the Canadian Securities Administrators and NASDAQ. As
new standards come into force, the Board will review


                                      -9-


and amend, where necessary and appropriate, its corporate governance practices
and the eligibility of the members of the Board on each committee and shall, if
necessary, make appropriate changes.

     The following is a description of the current committees of the Board:

     COMMITTEES OF THE BOARD

     Audit Committee
     ---------------

     The mandate of the Audit Committee includes assisting the Board in its
oversight of (i) the integrity of the Corporation's financial statements,
financial reporting process, system of internal controls over financial
reporting, and audit process, (ii) the Corporation's compliance with, and
process for monitoring compliance with, legal and regulatory requirements, (iii)
the independent auditors' qualifications and independence, and (iv) the
performance of the independent auditors. The current members of the Audit
Committee are Mr. Graeme K. Rutledge (chair), Dr. Colin Bier and Mr. John
Molloy.

     Under the listing requirements of NASDAQ, no director who is not
independent, may be appointed to the audit committee of a company. Mr. Molloy is
not independent under these listing requirements, as he is the President and
Chief Executive Officer of Parteq Research and Development Innovations, Queen's
University ("Parteq"). However, in accordance with the NASDAQ listing
requirements, the Board has resolved that the continued membership of Mr. Molloy
on the Audit Committee is required in the best interests of the Corporation and
its shareholders because of his knowledge of the Corporation and experience in
such matters.

     Compensation Committee
     ----------------------

     The mandate of the Compensation Committee includes reviewing the
compensation arrangements for the Corporation's employees, including executive
officers and directors, and making recommendations to the Board with respect to
such compensation arrangements, as well making recommendations to the Board with
respect to the Corporation's incentive compensation plans and equity-based plans
and to oversee succession planning. The Compensation Committee is also
responsible for preparing an annual report on executive compensation for
purposes of disclosure to shareholders. The current members of the Compensation
Committee are Dr. Colin Bier (chair), Mr. Peter Kruyt and Mr. Ronald M.
Nordmann.

     Nominating and Corporate Governance Committee
     ---------------------------------------------

     The mandate of the Nominating and Corporate Governance Committee is to
develop and recommend to the Board a set of corporate governance principles and
to prepare and review the disclosure with respect to, and the operation of, the
Corporation's system of corporate governance, before such disclosure is
submitted to the Board for its approval. The Nominating and Corporate Governance
Committee is responsible for the review and periodic update of the Corporation's
Code of Ethics which governs the conduct of the Corporation's directors,
officers and other employees. Moreover, the Nominating and Corporate Governance
Committee is mandated to examine, on an annual basis, the size and composition
of the Board and, if appropriate, recommend to the Board a program to establish
a Board comprised of members who facilitate effective decision-making. Finally,
the Nominating and Corporate Governance Committee shall identify individuals
qualified to become members of the Board, recommend to the Board nominees to be
put before shareholders at each annual meeting and recommend to the Board a
process for board, committee and director assessment. The current members of the
Nominating and Corporate Governance Committee are Mr. Ronald M. Nordmann
(chair), Dr. Frederick H. Lowy, Mr. Peter Kruyt and Dr. Emil Skamene.

     COMMUNICATIONS, INSIDER TRADING, CONFIDENTIAL INFORMATION AND DISCLOSURE
     POLICIES

     The Board is committed to an effective communications policy with all
stakeholders including shareholders, suppliers, advertisers, employees, agents
and members of the investment community. The Corporation is committed to
complying with all laws, regulations and policies which are applicable to it as
well as to best practices in the field. This commitment is evidenced, notably,
by the adoption in 2003 of a Disclosure and Trading Policy.



                                      -10-


     The Board or the Audit Committee reviews in advance all press releases
which disclose financial results or other non-routine matters. Other statutory
documents or documents required to be prepared, filed and delivered including,
without limitation, the annual report, proxy materials and annual information
form are reviewed by members of the Board and, where required, these documents
are approved by the Board.


INTEREST OF INSIDERS IN MATERIAL TRANSACTIONS

     On March 1, 2003, the Corporation entered into a management services
agreement with Picchio International into which Picchio Pharma intervened
(Picchio Pharma and Picchio International are sometimes referred to collectively
in this management proxy circular as the "Picchio Group"). All of the shares of
Picchio International are owned by Dr. Francesco Bellini, O.C., and his spouse.

     The management services agreement provides that Picchio International shall
provide the services of Dr. Bellini as Chairman and Chief Executive Officer of
the Corporation and provide the services of other members of the Picchio Group,
including all senior managers of Picchio Pharma. Under the agreement, the
Picchio Group is currently providing, and will continue to provide, on-going
regular consulting and advisory services, including services related to
reviewing existing and potential research and development activities, and
existing potential clinical programs, financing activities, partnering and
licensing opportunities, commercialization plans and programs, and advising and
assisting in investor relations activities.

     In consideration of all services rendered under the agreement, Picchio
International receives a monthly fee of $80,000. This amount includes all direct
and indirect costs and expenses, including travel and all other out-of-pocket
expenses, incurred by Dr. Bellini and the Picchio Group relating to the services
provided pursuant to such agreement. The agreement was amended as of October 30,
2003, to provide for the payment, from time to time, to Picchio International of
a discretionary amount as a performance based fee for services rendered. The
amount of such performance based fee, if any, will be determined by the Board at
its sole discretion. The term of the agreement is two years and each party has
the right to terminate such agreement at any time upon sending a written prior
notice of 180 days. The agreement provides that it shall be automatically
renewed for successive one year terms unless either party sends a prior written
notice of non-renewal to the other party at least 90 days prior to the then
current termination date.

     The management services agreement provides that the Picchio Group shall
not, without the Corporation's written consent, during the term of such
agreement and for the 24 months following the termination of the agreement,
carry on or be engaged in any business which is the same or similar to or in
competition in any material way with any of the businesses which the Corporation
now or which the Corporation shall, during the term of the agreement, carry on
anywhere in the world. The Picchio Group also agreed not to hire any of the
Corporation's employees during the term of the agreement and for the twelve
months following its expiration.


AUDITORS OF THE CORPORATION

     KPMG LLP, Chartered Accountants, have been the auditors of the Corporation
since September 1995. The Board recommends that shareholders vote for the
appointment of KPMG LLP, Chartered Accountants, as auditors of the Corporation
and the authorization of the Audit Committee to fix the auditors' remuneration.
THE PERSONS NAMED IN THE ENCLOSED FORM OF PROXY INTEND TO CAST THE VOTES TO
WHICH THE SHARES REPRESENTED BY SUCH PROXY ARE ENTITLED FOR THE REAPPOINTMENT OF
KPMG LLP, CHARTERED ACCOUNTANTS, AS AUDITORS OF THE CORPORATION FOR THE TERM

AUDIT COMMITTEE TO FIX THEIR REMUNERATION, UNLESS OTHERWISE DIRECTED BY THE
SHAREHOLDERS APPOINTING THEM.
