                                PROXY STATEMENT

     The accompanying proxy is solicited on behalf of the Board of Directors of
DUSA Pharmaceuticals, Inc. ("DUSA or the "Company"). If properly signed and
returned, and not revoked, the proxy will be voted in accordance with the
instructions it contains. The persons named in the accompanying proxy will vote
the proxy for the Board of Directors' slate of directors and for the other
matters listed on the proxy as recommended by the Board of Directors unless
contrary instructions are given.

     The Company, a New Jersey corporation, maintains principal executive
offices at 25 Upton Drive, Wilmington, Massachusetts. This proxy statement and
the accompanying form of proxy are being mailed to shareholders on or about
April 26, 2001. DUSA's Annual Report for 2000, including financial statements
for the year ended December 31, 2000, is being mailed to shareholders at the
same time.

SHAREHOLDERS ENTITLED TO VOTE.

     Holders of record of shares of DUSA common stock at the close of business
on April 19, 2001 are entitled to notice of, and to vote at, the annual meeting
and at any and all adjournments or postponements of the meeting. On the record
date there were 13,766,640 shares of common stock without par value ("Common
Stock") outstanding and entitled to vote. These shares were the only shares
outstanding of the Company. Each share entitles its owner to one vote. The
holders of one-third of the shares that are outstanding and entitled to vote at
the annual meeting must be present, in person or represented by proxy, in order
to constitute a quorum for all matters to come before the meeting.

     Other than the vote for the election of directors, which requires a
plurality of the votes cast, each matter to be submitted to the shareholders
requires the affirmative vote of a majority of the votes cast at the meeting.
For purposes of determining the number of votes cast with respect to a
particular matter, only those cast "For" or "Against" are included. Abstentions
and broker non-votes are counted only for purposes of determining whether a
quorum is present at the meeting. A broker "non-vote" occurs when a nominee
holding shares for a beneficial owner does not vote on a particular proposal
because the nominee does not have discretionary voting power with respect to
that item and has not received voting instructions from the beneficial owner.
The nominees may vote the shares only on matters deemed routine, such as the
election of directors and ratification of the selection of the auditors. They
cannot vote on a ratification of amendments to the Omnibus Plan if they do not
receive instructions from the beneficial owner and there would be a broker
non-vote on this matter. The Company's management currently owns less than one
percent of the Company's outstanding Common Stock.

HOW TO VOTE.

     If you are a shareholder of record (that is a shareholder who holds shares
in his/her own name), you can vote by signing, dating and returning your proxy
card in the enclosed postage-paid envelope. If you sign and return your proxy
card but do not give voting instructions, the shares represented by that proxy
will be voted "FOR" Proposals 1, 2 and 3 and will be voted in the proxy holder's
discretion as to other matters that may come before the annual meeting.

     If your shares are held in the name of a bank, broker or other holder of
record (that is, "street name"), you will receive instructions from the holder
of record that you must follow in order for your shares to be voted.

CHANGING YOUR VOTE.

     You may change your vote at any time before the proxy is exercised, by
executing and delivering a timely and valid later-dated proxy, by voting by
ballot at the annual meeting or by giving written notice to the Secretary of the
Company. Attendance at the meeting will not have the effect of revoking a proxy
unless you give proper written notice of revocation to the Secretary before the
proxy is exercised or you vote by written ballot at the annual meeting.

REDUCE DUPLICATE MAILINGS.

     The Company is required to provide an Annual Report and proxy statement to
all shareholders. If you are a shareholder of record and have more than one
account in your name or at the same address as other shareholders of record, you
may authorize the Company to discontinue mailings of multiple proxy statements,
Annual Reports and other information statements. To do so, please mark the
designated box on each proxy card for which you wish to discontinue to receive
duplicate documents. Your consent to cease delivery of the Annual Report, proxy
statements and other information statements shall be effective for five (5)
years or until you revoke your consent. You may revoke your consent at any time
by contacting Ms. Shari Lovell, in writing, at the Company's offices located at
181 University Avenue, Suite 1208, Toronto, Ontario M5H 3M7 Canada, or by
calling 1-800-607-2530. Delivery of individual copies of the documents shall
resume within thirty (30) days of our receipt of your request.

Meeting of Shareholders and/or until their successors have been duly elected and
qualified. The persons named on the accompanying proxy will vote all shares for
which they have received proxies for the election of the nominees named below
unless contrary instructions are given. In the event that any nominee should
become unavailable, shares will be voted for a substitute nominee unless the
number of directors constituting a full board is reduced. Directors are elected
by plurality vote.

                             DIRECTOR COMPENSATION

     Directors who are employees of the Company receive no cash compensation for
their services as directors or as members of committees. Outside directors
receive $25,000 per year, as annual compensation, regardless of the number of
meetings they attend. Directors serving on the Audit Committee receive an
additional $5,000 per year. Also, directors are paid out-of-pocket expenses
related to their attendance. Directors are awarded options to purchase 15,000
shares of common stock upon their initial election to the Board of Directors,
and options for 10,000 shares of common stock for each year of reelection.
During 2000, each outside director received a special award of options for
10,000 shares of common stock in recognition of their efforts on behalf of the
Company.

                      MEETINGS AND COMMITTEES OF THE BOARD

     During the year ended December 31, 2000, there were eight meetings of the
Board of Directors. Each incumbent director attended at least 75% of the

Committee, a Nominating Committee, and a Compensation Committee.

     The Audit Committee currently consists of all of the outside directors: Mr.

oversight of the Company's accounting functions and acts as liaison between the
Board of Directors and the outside independent auditors. The Committee reviews

planning and scope of the audits of the financial statements, the results of
those audits and the adequacy of internal accounting controls, and monitors
other corporate and financial policies. The Audit Committee met four times
during 2000.

     The Nominating Committee consists of the entire Board acting as a Committee

benefits which may be appropriate as the Company grows, and develops policies
and procedures. The Compensation Committee normally meets annually. It met in
February 2001 to establish compensation for the year and to award bonuses for
2000.

             PROPOSAL NO. 2 - RATIFICATION OF SELECTION OF AUDITORS

     The Board of Directors has appointed Deloitte & Touche LLP as the
independent auditors for the Company for the fiscal year 2001. Shareholder
ratification of the appointment is not required under the laws of the State of
New Jersey, but the Board has decided to ascertain the position of the
shareholders on the appointment. The Board of Directors will reconsider the
appointment if it is not ratified. A majority of the votes cast, in person or by
proxy, at the annual meeting is required for ratification. A representative of
Deloitte & Touche LLP will be present at the meeting to answer questions from
shareholders and will have the opportunity to make a statement on behalf of the
firm, if he or she so desires.

AUDIT FEES

     The aggregate fees billed by Deloitte & Touche LLP for professional
services rendered for the audit of the Company's annual financial statements for
the fiscal year ended December 31, 2000, and for the reviews of the financial
statements included in the Company's Quarterly Reports on Form 10-Q during the
fiscal year were $123,000.

FINANCIAL INFORMATION SYSTEMS DESIGN AND IMPLEMENTATION FEES

     There were no fees billed by Deloitte & Touche LLP for professional
services rendered for information technology services relating to financial
information systems design and implementation for the fiscal year ended December

the Company, other than for the services described above under "Audit Fees" and

year ended December 31, 2000, were $37,000.

         THE BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" THIS PROPOSAL.

                 PROPOSAL NO. 3 - RATIFICATION OF AMENDMENTS TO
                  THE COMPANY'S 1996 OMNIBUS PLAN, AS AMENDED.

     The Company's 1996 Omnibus Plan, as amended (the "Plan"), was ratified by
the Company's shareholders at the 1996 Annual Meeting of Shareholders. In June
1997, and again in June 1998, the Company's shareholders approved several
amendments to the 1996 Omnibus Plan.

     The Plan currently provides for the granting of awards to purchase up to a
maximum of 15% of the number of shares of the Company's Common Stock
outstanding. The Plan authorizes the granting of nonqualified stock options
("NQSOs"), incentive stock options ("ISOs"), stock appreciation rights (the
right to receive, upon surrender of the right, but without payment, an amount
payable in cash)("SARs"), and restricted stock or other securities to directors,
officers, employees and consultants of the Company. The Plan provides that
NQSOs, ISOs and SARs shall vest over four (4) years at a rate of twenty-five
percent (25%) per year subject to certain conditions involving continuous
periods of service or engagement. The exercise price of options shall be not
less than the fair market value of the Company's Common Stock on the date of the
grant. Grantees may pay the exercise price by surrender of the Company's Common
Stock or cash or a combination of stock and cash. The options expire ten (10)
years from the date of the grant. The Plan may be administered by a Committee or
the Board of Directors.

     Grants may be made to key employees and consultants of the Company solely
at the discretion of the Board of Directors or the Committee. Directors of the
Company are eligible to receive grants of NQSOs, as determined by the members of
the Board, subject to the terms and conditions of the Plan. In addition, each
individual who agrees to become a director receives a grant of 15,000 options to
purchase shares of Common Stock of the Company. Each individual who is a
continuing director on June 30th of each year automatically receives 10,000
options to purchase shares of Common Stock of the Company. The options granted
pursuant to these automatic grants vest immediately.

     As of April 1, 2001, there were 1,023,750 NQSOs and 807,250 ISOs and 2,500
shares in other awards outstanding pursuant to the Plan, totaling approximately
thirteen percent (13%) of shares outstanding, leaving a total of only 231,496
awards available for grant under the Plan as of that date. On June 30, 2001,
following the 2001 Annual Meeting of Shareholders, an additional 25,000 NQSOs
will automatically be granted to the members of the Board of Directors according
to the Plan.

     The Board of Directors has approved two additional amendments to the Plan.
The first amendment would increase the number of shares available for issuance
upon exercise of options or other awards granted under the Plan from fifteen
percent (15%) of the number of shares of Common Stock outstanding to twenty
percent (20%) of the number of shares of Common Stock outstanding, or a maximum
of 2,753,328 shares. Under the present cap of fifteen percent (15%) of shares
outstanding, only a limited number of options remain available for grants. The
Board of Directors recognized that DUSA has hired and expects to continue to
hire a significant number of employees in the next year or so. The Board of
Directors believes that the proposed increase in the number of shares available
for issuance under the Plan is necessary to continue the effectiveness of the
Plan in attracting, motivating and retaining employees, consultants, and
directors with appropriate experience and ability; and to increase grantees'
alignment of interest with the Company's shareholders.

     The second amendment approved by the Board of Directors provides that, for
2001 only, the automatic grant of options to continuing directors be reduced
from 10,000, to 5,000 options to purchase shares of the Company's Common Stock.
The Board of Directors has determined that this amendment was necessary in order
to ensure that sufficient options were available for year-end grants to
employees and consultants for 2000, and for grants to new hires prior to the
ratification of the amendment to increase the shares eligible for issuance under
the Plan.

     A majority of the votes cast by shareholders entitled to vote, whether in
person or by proxy, is required in order to ratify the amendments to the Plan.

     The full text of the proposed amended 1996 Omnibus Plan is attached to this
Proxy Statement as Appendix A and reference is made to such attachment for a
complete statement of the amendments to the Plan.

     THE BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" THE AMENDMENTS TO THE 1996
OMNIBUS PLAN.

                        BOARD AUDIT COMMITTEE REPORT(1)

The Audit Committee assists the Board of Directors by providing oversight of the
Company's financial reporting process and the independent auditors. Management
is responsible for preparing the Company's financial statements and the
Company's independent auditors are responsible for auditing those financial
statements. The Audit Committee is responsible for overseeing the conduct of
these activities by the Company's management and the independent auditors. A
brief description of the responsibilities of the Committee is set forth above
under the caption "Meetings and Committees of the Board".

     During 2000, the Audit Committee was composed of three non-employee
directors: Mr. Lufkin, Mr. Abeles and Mr. Doherty. The Committee operates under
a written charter adopted and approved by the Board of Directors. Each Committee
member is independent as defined by NASD listing standards. A copy of the Audit
Committee Charter is attached to this proxy statement as Appendix B.

     The Committee has reviewed and discussed the audited consolidated financial
statements for the fiscal year ended December 31, 2000 with management. The
Committee also discussed with Deloitte & Touche LLP, the independent auditors,
the matters required to be discussed by Statement on Auditing Standards No. 61,
"Communication with Audit Committees." In addition, the Committee received from
Deloitte & Touche the written disclosures and the letter required by
Independence Standards Board Standard No. 1, "Independence Discussions with
Audit Committees," and the Committee discussed with the independent auditors
their independence from the Company and its management. Additionally, the
Committee considered whether their provision of services to the Company beyond
those rendered in connection with their audit and review of the Company's
consolidated financial statements was compatible with maintaining their
independence and the fees and costs billed and to be billed for those services
as shown on page 3 of this proxy statement.

     Based on its review, and the discussions with the Company's management and
its independent auditors, the Committee recommended to the Board of Directors
that the Company's audited consolidated financial statements for the fiscal year
ended December 31, 2000 be included in the Company's Annual Report on Form 10-K.
The Committee has also recommended the selection of the Company's independent
auditors, and, the Board has selected, Deloitte & Touche LLP as the Company's
independent auditors for the fiscal year ended December 31, 2001.

        BOARD COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION(1)

     The Compensation Committee of the Board of Directors (the "Committee") is
composed of two (2) non-employee directors. The Committee is responsible for
setting and administering the policies which govern annual executive salaries
and cash bonus awards, and recommends participants and amounts of stock option
awards to the Company's Board of Directors. The Committee evaluates, on a yearly
basis, the performance, and determines the compensation of, the executive
officers of DUSA. The Committee evaluates compensation based upon the
achievement by the individual of corporate goals, and the performance of
individual responsibilities. DUSA's President and Chief Executive Officer, Dr.
D. Geoffrey Shulman, is not a member of the Committee, however, the Committee
sought input from Dr. Shulman regarding the performance of DUSA's Vice
Presidents, as well as his recommendations for their compensation. Dr. Shulman
was present, at the invitation of the Committee, at its meeting.

     DUSA's executive compensation programs consist of base salary, cash bonus
incentives, and stock option awards. The goals of the Company's executive
officer compensation policies are to attract, retain, and reward executive
officers who contribute to DUSA's success, to align executive officer
compensation with DUSA's performance and to motivate executive officers to
achieve the Company's business objectives. The executive officers were evaluated
by the Committee against established goals for 2000 within each executive
officer's area of responsibility, including the receipt of marketing approval of
the commercial version of the BLU-U(TM) brand light device, coordinating
marketing, manufacturing and technology development operations for the
anticipated launch of products, and securing additional financial resources for
DUSA through completion of a private placement of shares of DUSA's common stock
in March 2000.

     With regard to base salary, the Committee believes that DUSA's officers
should be compensated at levels comparable to the base salary of executive
officers at similar small public biotechnology or pharmaceutical companies.
During 2000, the Committee considered survey data of companies in these groups
in setting the salaries for the Company's top executive officers which was
prepared by independent consultants.

     In determining appropriate levels of cash bonus awards for 2000, the
Committee considered the specific corporate goals of DUSA and personal goals set
for each of the executive officers. Generally, DUSA's Vice Presidents are
eligible to receive up to 30% of their base salary as a cash bonus award. The
Committee concluded that DUSA's operational performance, particularly
coordinating the scale-up of production and the launch of DUSA's first new drug
application in September, 2000, justified favorable consideration of performance
with regard to bonus awards. However, in establishing the bonus award amounts,
the Committee recognized that certain Company goals for 2000 were not achieved.
Accordingly, DUSA's Vice Presidents received cash bonus awards ranging from
approximately 23% to 27% of their base salaries. These cash awards were paid in
2001.

     The Committee also is using the survey data from independent consultants to
monitor and evaluate the long-term incentive compensation levels of its officers
and directors. The Committee believes that a strong stock ownership program is
essential to the long-term growth of the Company. In 2000, DUSA's key executive
officers received awards of stock options to emphasize the long-term focus
required for success in the pharmaceutical industry.

COMPENSATION OF THE PRESIDENT AND CHIEF EXECUTIVE OFFICER

     Dr. Shulman's base salary and cash bonus award for 2000 were determined
with reference to the same measures used for all DUSA's executive officers, but
with particular emphasis on the maintenance of our financial strength and the
successful transition from a development-stage company to an operating company.
Dr. Shulman's base salary for 2000 was $340,000. With regard to a cash bonus
award, Dr. Shulman is eligible to receive up to 50% of base salary plus
additional amounts for outstanding performance. For 2000, Dr. Shulman's bonus
award was approximately 43% of his base salary. Dr. Shulman's cash bonus award
was paid to him in 2001. The Committee has determined that for 2001, Dr.
Shulman's base salary shall remain the same. The Compensation Committee
exercised its subjective judgment and discretion in determining the amounts of
Dr. Shulman's base salary, bonus award, and stock option awards for 2000.

                             SHAREHOLDER PROPOSALS

     In order to be included in the Board of Directors' proxy statement and
proxy card for the 2002 Annual Meeting of Shareholders, a shareholder proposal
must be received by the Company on or before December 28, 2001. Proposals should
be directed to the attention of Ms. Shari Lovell at the Company's offices
located at 181 University Avenue, Suite 1208, Toronto, Ontario M5H 3M7 Canada,
or to the attention of the Secretary, Nanette W. Mantell, Esq., c/o Reed Smith
LLP, Princeton Forrestal Village, 136 Main Street - Suite 250, Princeton, New
Jersey 08540.

     In addition, if a shareholder wishes to present a proposal at the Company's
2002 Annual Meeting which is not intended to be included in the Company's proxy
statement for that meeting, the Company must receive written notice of the
shareholder proposal by March 12, 2002. If DUSA does not receive timely notice
of such a shareholder proposal, the Company will retain its discretionary
authority to vote proxies on such proposals even if it is not specifically
reflected on the proxy card, and shareholders have not had an opportunity to
vote on the proposal by proxy.

               COMPLIANCE WITH SECTION 16(a) OF THE EXCHANGE ACT

     Under the securities laws of the United States, the Company's directors,
executive officers and any person holding more than ten percent (10%) of our
common stock are required to report their ownership of our common stock and any
changes in that ownership to the Securities and Exchange Commission on Forms 3,
4 and 5. Based on our review of the copies of such forms we have received, DUSA
believes that all of our officers and directors complied with all filing
requirements applicable to them with respect to transactions during fiscal 2000.
Other than INVESCO Funds Group, Inc., Cooper Hill Partners, LLC, Mr. Jeffrey
Casdin, and Pequot Capital Management Inc., the Company is not aware of any
person who holds greater than 10% beneficial ownership. In making these
statements, we have relied on the written representations of our directors and

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

     Lane and Mantell, a professional corporation, which served as our legal

be brought before the meeting. However, if any other matter properly comes
before the meeting, the persons named in the enclosed proxy will vote the proxy

     The cost of preparing and mailing the enclosed material will be borne by

will receive no additional compensation) to solicit proxies. The Company intends
to request banks and brokers holding shares of DUSA Pharmaceuticals, Inc. common
stock to forward copies of the proxy materials to those persons for whom they
hold shares and to request authority for the execution of proxies. The Company
will reimburse banks and brokers for their out-of-pocket expenses. The Company
has retained its transfer agent, American Stock Transfer & Trust Company, to aid
in the solicitation, at an estimated cost of under $10,000.

       ARTICLE VI - GRANTS OF STOCK OPTIONS TO EMPLOYEES AND CONSULTANTS

     The Committee may grant Options, as follows, which may be designated as (i)
NQSOs or (ii) ISOs intended to qualify under Code Section 422:

     (a) Nonqualified Stock Options.  A NQSO is a right to purchase a specified
number of shares of Common Stock during such specified time as the Committee may
determine, not to exceed ten (10) years, at a price determined by the Committee
that, unless deemed otherwise by the Committee, is not less than the Fair Market
Value of the Common Stock on the date the option is granted. NQSOs granted to
Employees and Consultants shall vest at the rate of one quarter of the total
granted on each of the first, second, third and fourth anniversaries of the day
of the grant, subject to satisfaction of certain conditions involving continuous
periods of service or engagement.

          (i) The purchase price of the Common Stock subject to the NQSO may be
     paid in cash. At the discretion of the Committee, the purchase price may
     also be paid by the tender of Common Stock or through a combination of
     Common Stock and cash or through such other means as the Committee
     determines are consistent with the Plan's purpose and applicable law. No
     fractional shares of Common Stock will be issued or accepted.

          (ii) Without limiting the foregoing, to the extent permitted by law
     (including relevant state law), (A) the Committee may agree to accept, as
     full or partial payment of the purchase price of Common Stock issued upon
     the exercise of the NQSO, a promissory note of the person exercising the
     NQSO evidencing the person's obligation to make future cash payments to the
     Company, which promissory note shall be payable as determined by the
     Company (but in no event later than five (5) years after the date thereof),
     shall be secured by a pledge of the shares of Common Stock purchased and
     shall bear interest at a rate established by the Committee and (B) the
     Committee may also permit the person exercising the NQSO, either on a
     selective or aggregate basis, to simultaneously exercise the NQSO and sell
     the shares of Common Stock acquired, pursuant to a brokerage or similar
     arrangement approved in advance by the Committee, and use the proceeds from
     sale as payment of the purchase price of such Common Stock.

     (b) Incentive Stock Options.  An ISO is an Award in the form of an Option
to purchase Common Stock that complies with the requirements of Code Section 422
or any successor section.

          (i) The aggregate Fair Market Value (determined at the time of the
     grant of the Award) of the shares of Common Stock subject to ISOs which are
     exercisable by one person for the first time during a particular calendar
     year shall not exceed $100,000. To the extent that ISOs granted to an
     employee exceed the limitation set forth in the preceding sentence, ISOs
     granted last shall be treated as NQSOs.

          (ii) No ISO may be granted under this Plan on or after the tenth
     anniversary of the date this Plan is adopted or the date this Plan is
     approved by shareholders, whichever is earlier.

          (iii) No ISO may be exercisable more than:

             (A) in the case of an Employee who is not a Ten Percent
        Shareholder, within the meaning of Code Section 422, on the date the ISO
        is granted; ten (10) years after the date the ISO is granted; and

             (B) in the case of an Employee who is a Ten Percent Shareholder,
        within the meaning of Code Section 422, on the date the ISO is granted,
        five (5) years after the date the ISO is granted.

          (iv) The exercise price of any ISO shall be determined by the
     Committee and shall be no less than:

             (A) in the case of an Employee who is not a Ten Percent
        Shareholder, on the date the ISO is granted, the Fair Market Value of
        the Common Stock subject to the ISO on such date; and

             (B) in the case of an Employee who is a Ten Percent Shareholder, on
        the date the ISO is granted, not less than 110 percent of the Fair
        Market Value of the Common Stock subject to the ISO on such date.

          (v) The Committee may provide that the option price under an ISO may
     be paid by one or more of the methods available for paying the option price
     of an NQSO.

          (vi) ISOs shall vest at the rate of one quarter of the total granted
     on each of the first, second, third and fourth anniversaries of the day of
     the grant, subject to satisfaction of certain conditions involving
     continuous periods of service or engagement.

 ARTICLE VII - GRANTS OF STOCK APPRECIATION RIGHTS TO EMPLOYEES AND CONSULTANTS

     An SAR is a right to receive, upon surrender of the right, but without
payment, an amount payable in cash.

          (i) The amount payable with respect to each SAR shall be equal in
     value to the applicable percentage of the excess, if any, of the Fair
     Market Value of a share of Common Stock on the exercise date over the
     exercise price of the SAR. The exercise price of the SAR shall be
     determined by the Committee and shall not be less than the Fair Market
     Value of a share of Common Stock on the date the SAR is granted.

          (ii) In the case of an SAR granted in tandem with an ISO to an
     Employee or Consultant who is a Ten Percent Shareholder on the date of such
     grant, the amount payable with respect to each SAR shall be equal in value
     to the applicable percentage of the excess, if any, of the Fair Market
     Value of a share of Common Stock on the exercise date over the exercise
     price of the SAR, which exercise price shall not be less than 110% of the
     Fair Market Value of a share of Common Stock on the date the SAR is
     granted.

          (iii) The applicable percentage and exercise price shall be
     established by the Committee at the time the SAR is granted.

          (iv) SARs shall vest at the rate of one quarter of the total granted
     on each of the first, second, third and fourth anniversaries of the day of
     the grant, subject to satisfaction of certain conditions involving
     continuous periods of service or engagement.

     ARTICLE VIII - GRANTS OF RESTRICTED STOCK TO EMPLOYEES AND CONSULTANTS

     Restricted Stock is Common Stock of the Company that is issued to a
participant at a price determined by the Committee, which price may be zero, and
is subject to restrictions on transfer and/or such other restrictions on
incidents of ownership as the Committee may determine.

     ARTICLE IX - GRANTS OF PERFORMANCE AWARDS TO EMPLOYEES AND CONSULTANTS

     A Performance Award granted under the Plan (i) may be denominated or
payable in cash, Common Stock (including without limitation, Restricted Stock),
other securities or other Awards and (ii) shall confer on the holder thereof the
right to receive payments, in whole or in part, upon the achievement of such
performance goals during such performance periods as the Committee shall
establish. Subject to the terms of the Plan and any applicable Award agreement,
the performance goals to be achieved during any performance period, the length
of any performance period, the amount of any Performance Award granted and the
amount of any payment or transfer to be made pursuant to any Performance Award
shall be determined by the Committee.

   ARTICLE X - GRANTS OF OTHER STOCK-BASED INCENTIVE AWARDS TO EMPLOYEES AND
                                  CONSULTANTS

     The Committee may from time to time grant Awards under this Plan that
provide the participant with the right to purchase Common Stock or that are
valued by reference to the Fair Market Value of the Common Stock (including, but
not limited to, phantom securities or dividend equivalents). Such Awards shall
be in a form determined by the Committee (and may include terms contingent upon
a change of control of the Company), provided that such Awards shall not be
inconsistent with the terms and purposes of the Plan. The Committee will
determine the price of any Award and may accept any lawful consideration.

               ARTICLE XI - GRANTS OF STOCK OPTIONS TO DIRECTORS

     (a) Directors of the Company shall be eligible to receive NQSOs under the
Plan. Each individual who agrees to become a Director shall receive, on June
30th of the first year of such service and without the exercise of the
discretion of any person, a NQSO under the Plan relating to the purchase of
15,000 shares of Common Stock at an exercise price equal to the Fair Market
Value. Thereafter, on June 30th of each year, each individual who is a
continuing Director shall receive, without the exercise of the discretion of any
person, a NQSO under the Plan relating to the purchase of 10,000 shares of
Common Stock.

          (i) Notwithstanding the preceding, all continuing directors on June
     30, 2001, shall receive, for that year only, a NQSO under the Plan relating
     to the purchase of 5,000 shares of Common Stock.

     (b) The exercise price of each share of Common Stock subject to a NQSO
granted to a Director shall equal the Fair Market Value of a share of Common
Stock on the date such NQSO is granted. The
                                        4
   21

option price of a NQSO granted to a Director may be paid in accordance with
Article VI (a) (i) and (ii) of the Plan.

     (c) Each automatic NQSO granted to a Director shall vest in full on the
date of the grant. The NQSOs to directors shall have a term not to exceed ten
(10) years from the date of grant, or, if later, the date the Grantee becomes a
Director. Notwithstanding the exercise period of any NQSO granted to a Director,
all such NQSOs shall immediately become exercisable upon (i) the death of a
Director while serving as such, or (ii) a Change of Control.

                       ARTICLE XII - EXERCISE OF OPTIONS

     Options granted under the Plan may be exercised by a Grantee only while the
Employee, Consultant or Director is and, continuously since the date the Option
was granted, has been an Employee, Consultant or Director of the Company or one
of its subsidiaries, except that:

     (i) if the Grantee's termination of employment is other than for Cause, any
Options held by the Grantee may be exercised, to the extent then exercisable,
for a period of three months after the date of such termination of employment;

     (ii) if such termination of employment is by reason of retirement or
disability, any Options held by the Grantee at the time of death or disability
will be exercisable for a period of 12 months after the date of such termination
of employment;

     (iii) in the event of death after termination of employment pursuant to (i)
or (ii) above, the person or persons to whom the Grantee's rights are
transferred by will or the laws of descent and distribution shall have a period
of three years from the date of termination of the Grantee's employment to
exercise any Options which the Grantee could have exercised during such period;
and

     (iv) in the event of the death of an Grantee while employed, any Options
then held by the Grantee shall become fully and immediately exercisable and may
be exercised by the person or persons to whom the Grantee's rights are
transferred by will or the laws of descent and distribution for a period of
three years after the Grantee's death. In no event, however, shall any Option be
exercisable after the date specified in Article VI, as applicable.

     An Option granted hereunder shall be exercisable, in whole or in part, only
by written notice delivered in person or by mail to the Secretary of the Company
at its principal office, specifying the number of shares of Common Stock to be
purchased and accompanied by payment thereof and otherwise in accordance with
the option agreement pursuant to which the Option was granted.

     In the event of a Change of Control affecting the Company, then,
notwithstanding any provision of the Plan or of any provisions of any Award
agreements entered into between the Company and any participant to the contrary,
all Awards that have not expired and which are then held by any participant (or
the person or persons to whom any deceased participant's rights have been
transferred) shall, as of such Change of Control, become fully and immediately
vested and exercisable and may be exercised for the remaining term of such
Awards.

                        ARTICLE XIII - AWARD AGREEMENTS

     Each Award granted under the Plan shall be evidenced by an Award agreement
between the Grantee and the Company, setting forth the number of shares of
Common Stock, SARs, or units subject to the Award and such other terms and
conditions applicable to the Award not inconsistent with the Plan as the
Committee may deem appropriate.

                         ARTICLE XIV - TAX WITHHOLDING

     The Committee may establish such rules and procedures as it considers
desirable in order to satisfy any obligation of the Company or any subsidiary to
withhold federal income taxes or other taxes with respect to any Award made
under the Plan. Such rules and procedures may provide (i) in the case of Awards
paid in shares of Common Stock, that the person receiving the Award may satisfy
the withholding obligation by instructing the Company to withhold shares of
Common Stock otherwise issuable upon exercise of such Award in order to satisfy
such withholding obligation and (ii) in the case of an Award paid in cash, that
the withholding obligation shall be satisfied by withholding the applicable
amount and paying the net amount in cash to the participant.

   22

                   ARTICLE XV - DILUTION OR OTHER ADJUSTMENT

     If the Company is a party to any merger or consolidation, or undergoes any
separation, reorganization or liquidation, the Board of Directors of the Company
shall have the power to make arrangements, which shall be binding upon the
holders of unexpired Awards, for the substitution of new Awards for, or the
assumption by another corporation of, any unexpired Awards then outstanding
hereunder. In the case of any ISO, such action shall be taken only in the manner
and to the extent permitted by Sections 422 and 424 of the Code. In addition, in
the event of a reclassification, stock split, combination of shares, separation
(including a spin-off), dividend on shares of the Common Stock payable in stock,
or other similar change in capitalization or in the corporate structure of
shares of the Common Stock of the Company, the Committee shall conclusively
determine the appropriate adjustment in the option prices of outstanding
Options, in the number and kind of shares or other securities as to which
outstanding Awards shall be exercisable, and in the aggregate number of shares
with respect to which Awards may be granted. In the case of any ISO, any such
adjustment in the shares or other securities subject to the ISO (including any
adjustment in the Option price) shall be made in such manner as not to
constitute a modification as defined by Section 424(h)(3) of the Code and only
to the extent permitted by Sections 422 and 424 of the Code.

                          ARTICLE XVI - ASSIGNABILITY

     No Award granted under this Plan shall be sold, pledged, assigned or
transferred other than by will or the laws of descent and distribution, and
Awards shall be exercisable during the Grantee's lifetime only by the Grantee.

                    ARTICLE XVII - AMENDMENT OR TERMINATION

     The Board of Directors of the Company may at any time amend, suspend or
terminate the Plan subject to the regulatory requirements of the United States
Securities and Exchange Commission and the National Association of Securities
Dealers or other applicable federal or state regulatory authority, provided,
however, that no change in any Awards previously granted may be made without the
consent of the holder thereof.

                       ARTICLE XVIII - GENERAL PROVISIONS

     (a) Common Stock acquired pursuant to the exercise of an Option under the
Plan shall be subject to applicable transfer restrictions under applicable
Canadian or United States federal securities laws, under the requirements of any
national securities exchange or market upon which such Common Stock are then
listed and/or traded, and under any blue sky or state securities laws applicable
to such Common Stock. If the instrument evidencing the Option so provides,
Common Stock issued on exercise of an Option granted under the Plan may upon
issuance be subject to additional restrictions.

     (b) At the discretion of the Board of Directors, the Options and the shares
of Common Stock received upon exercise of an Option shall be registered with the
United States Securities and Exchange Commission and any applicable state
securities law commission. In the absence of such registration, both the Options
and the shares of Common Stock underlying the Options: 1) will be issued only
pursuant to an exemption from registration; 2) cannot be sold, pledged, traded
or otherwise disposed of in the absence of an effective registration statement
or an opinion of counsel satisfactory to the Company that such registration is
not required; 3) will bear an appropriate restrictive legend to that effect.
Individuals receiving Options may be required to sign an investment letter
satisfactory to the Board of Directors at the time the Options are exercised,
and may be required to comply with any other requirements for an exemption under
the Securities Act of 1933 and any applicable state securities law exemption.

     (c) The proceeds received by the Company from the sale of Common Stock,
pursuant to the exercise of Options granted under the Plan, shall be added to
the Company's general funds and used for general corporate purposes.

     (d) No Awards may be exercised by the holder thereof if such exercise, and
the receipt of cash or stock thereunder, would be, in the opinion of counsel
selected by the Company, contrary to law or the regulations of any duly
constituted authority having jurisdiction over the Plan.

     (e) No Award recipient shall have any rights as a shareholder with respect
to any shares subject to Awards granted to him or her under the Plan prior to
the date as of which he or she is actually recorded as the holder of such shares
upon the stock records of the Company.

     (f) Nothing contained in the Plan or in Awards granted thereunder shall
confer upon any Employee, Consultant or Director any right to continue in the
employ of the Company or any of its

                                        6
   23

subsidiaries or interfere in any way with the right of the Company or any of its
subsidiaries to terminate his or her employment at any time.

                          ARTICLE XIX - EFFECTIVE DATE

     The Plan shall become effective on the date of its adoption by the Board of
Directors of the Company subject to approval of the Plan by the holders of a
majority of the outstanding voting shares of the Company within 12 months after
the date of the Plan's adoption by said Board of Directors. In the event of the
failure to obtain such shareholder approval, the Plan shall be null and void and
the Company shall have no liability thereunder. No Award granted under the Plan
shall be exercisable until such shareholder approval has been obtained.

                            ARTICLE XX - TERMINATION

     No Award may be granted under the Plan on or after the date which is ten
years following the effective date specified in Article XIX, but Awards
previously granted may be exercised in accordance with their terms.
