                            WARRANT AGREEMENT BETWEEN

          INSTITUTE FOR MEDICAL STUDIES, INC. AND THEHEALTHCHANNEL.COM

                            DATED SEPTEMBER 29, 1999

<PAGE>

THIS WARRANT AND THE SHARES ISSUABLE UPON EXERCISE OF THIS WARRANT HAVE NOT BEEN
REGISTERED UNDER THE SECURITIES ACT OF 1933 AND MAY NOT BE SOLD OR TRANSFERRED
IN THE ABSENCE OF SUCH REGISTRATION, OR APPLICABLE EXEMPTIONS FROM THE
REGISTRATION REQUIREMENTS UNDER SUCH LAWS, AND COMPLIANCE WITH THE REQUIREMENTS
OF SECTION 8 OF THIS WARRANT.

                                WARRANT AGREEMENT

         This Warrant Agreement (this "WARRANT" or this "AGREEMENT") is entered
into as of September 29, 1999 between INSTITUTE FOR MEDICAL STUDIES, INC., a
California corporation ("HOLDER"), and thehealthchannel.com, a Delaware
corporation (the "COMPANY"). This Warrant is issued in consideration of Holder's
services under the Website Services and Revenue Sharing and Services Agreement
(the "SERVICES AGREEMENT") between Holder and the Company dated as of September
29, 1999. The Company hereby grants to Holder a warrant to purchase, subject to
the provisions of this Agreement, up to one million five hundred thousand
(1,200,000) shares of the Company's Common Stock (the "COMMON STOCK"). The price
to be paid for each such share purchased upon an exercise of this Warrant shall
be Ten Cents ($0.10). The number of shares of Common Stock to be received upon
the exercise of this Warrant and the price to be paid for a share of Common
Stock may be adjusted from time to time as set forth below. The shares of Common
Stock deliverable upon such exercise, and as adjusted from time to time, are
referred to below as "WARRANT SHARES" and the exercise price of a share of
Common Stock in effect at any time and as adjusted from time to time is referred
to below as the "EXERCISE PRICE."

1.       EXERCISE OF WARRANT. As used in this Warrant, the "EXERCISE PERIOD"
shall mean the period between July 1, 2000 and September ___, 2002. Subject to
Section 8 hereof, this Warrant may be exercised in whole or in part at any time
or from time to time during the Exercise Period by presentation and surrender of
this Warrant to the Company at its principal office, accompanied by a statement
of the number of shares being purchased and payment of the Exercise Price for
the purchased shares in accordance with Section 2. If this Warrant should be
exercised in part only, the Company shall, upon surrender of this Warrant for
exercise and cancellation, execute and deliver a new Warrant evidencing the
rights of Holder thereof to purchase the balance of the shares purchasable
hereunder. Upon receipt by the Company of this Warrant and the purchase price
for the shares being purchased upon such an exercise, Holder shall be deemed to
be the holder of record of the shares of Common Stock issuable upon such
exercise, notwithstanding that the stock transfer books of the Company shall
then be closed or that certificates representing such shares of Common Stock
shall not then be actually delivered to Holder. Following proper exercise of
this Warrant, a certificate for the shares purchased, registered in the name of
the person entitled to receive such shares, shall be promptly delivered to such
person. No fractional shares shall be issued upon the exercise of this Warrant.
Any fraction of a share called for upon any exercise hereof shall be canceled.
If there is (a) any merger of the Company with or into another entity (other
than a merger of either such corporation with the other or in which it is the
continuing entity and which does not result in any reclassification, capital
reorganization or other change of outstanding shares issuable upon exercise of
this Warrant), or (b) any sale or other conveyance (or series of related sales
or conveyances) of all or substantially all of the property or business of the
Company, or (c) or any sale by the Company of shares constituting after such
sale a majority of the outstanding shares of such corporation, or (d) the
liquidation and winding up of the Company, Holder shall be given prior written
notice of the transaction under Section 7 and this Warrant shall become
immediately and fully exercisable upon the later of Holder's receipt of such
notice or six (6) months after the date of this Warrant Agreement. If the
Company shall file a registration statement under the Securities Act of 1933, as
amended, to register any of its securities, either for its own account or the
account of a security holder or holders, other than a registration statement
relating solely to employee benefit plans or a registration statement relating
solely to a Securities and Exchange Commission Rule 145 transaction, Holder
shall have the related registration rights described in EXHIBIT A to this
Warrant and this Warrant shall become fully exercisable upon the effectiveness
of such registration statement.

2.       PAYMENT OF THE EXERCISE PRICE. Payment of the Exercise Price for any
Warrant Shares on any exercise of this Warrant shall be made, at Holder's
option: (a) in cash; and/or (b) by forgiveness of indebtedness owed to Holder by
the Company; and/or (c) by transfer or surrender to the Company and delivery of
the certificates representing such shares, concurrently with such exercise, of
shares of Common Stock of the Company (which shares shall have been owned by
Holder for at least six months) valued on the basis of the Fair Market Value of
the Common Stock on the next business day before the date of such exercise. For
this purpose, the "FAIR MARKET Value" of the Common Stock shall mean: (i) if the
Common Stock is listed or admitted to trade on a securities exchange, the
closing sale price of a share of the

<PAGE>

Common Stock on the composite tape of the principal securities exchange on which
the Common Stock is so listed or admitted to trade; or, (ii) if the Common Stock
is not listed or admitted to trade on a securities exchange, the reported
closing sale price or, if such prices are not reported, the mean between the
last reported bid and asked prices, for a share of the Stock as furnished by the
National Association of Securities Dealers, Inc. through NASDAQ or a similar
organization if NASDAQ is no longer reporting such information; or (iii) if the
Common Stock is not listed or admitted to trade on a securities exchange and if
prices for the Common Stock are not so furnished through NASDAQ or a similar
organization, the last reported sale price or, if such prices are not reported,
the mean between the last reported bid and asked prices, for a share of the
Stock in the Over-the-Counter market as reported through the Bulletin Board, the
"pink sheets" or otherwise; or (v), if (i)-(iv) are not applicable, the fair
market value of a share of the Common Stock as reasonably determined in good
faith by the Company's Board of Directors. The Fair Market Value as of any date
under (i)-(iv) shall be determined by the trading price on that date, or if
there was no trading price on that date, on the next preceding date on which the
Common Stock was traded.

3.       WARRANTIES OF THE COMPANY. The Company hereby warrants and represents
to Holder the following:

         (a) All Warrant Shares shall, upon their issuance, be duly authorized,
validly issued, fully paid and nonassessable, and free of any liens and
encumbrances except for restrictions on transfer under applicable securities
laws and under existing agreements between Holder and the Company.

         (b) This Warrant Agreement and the Services Agreement have been duly
authorized and executed by the Company and are valid and binding obligations of
the Company, enforceable against the Company in accordance with their terms,
subject to applicable bankruptcy, insolvency or other laws of general
application affecting the enforcement of creditors' rights.

         (c) The Company is not a party to, bound by or subject to any agreement
or instrument, or any judgment, order or decree of any court or governmental
agency or authority, or any law or regulation, which would be violated by its
entering into or carrying out this Warrant Agreement or the Services Agreement.

         (d) The execution and delivery of this Warrant Agreement and the
Services Agreement by the Company, and the issuance of the Warrant Shares by the
Company pursuant to this Warrant Agreement, will not conflict with or breach any
provision of the Company's Certificate of Incorporation or Bylaws or any
agreement to which the Company is a party.

         (e) On a fully diluted basis, assuming the complete exercise and
conversion of all outstanding rights and options to acquire, directly or
indirectly, shares of the Company's capital stock (whether or not presently
exercisable), including (without limitation) exchange rights of the holders of
shares of common stock of Biologix International Ltd., but excluding this
Warrant, the total number of shares of the Company's common stock would not
exceed 106,819,558 shares.

4.       EXCHANGE, TRANSFER OR LOSS OF WARRANT. This Warrant is exchangeable,
without expense, at the option of Holder, upon presentation and surrender hereof
to the Company for other Warrants in this form of different denominations
entitling the holder thereof to purchase in the aggregate the same number of
shares of Common Stock purchasable hereunder. Subject to Section 8, upon
surrender of this Warrant to the Company accompanied by an assignment duly
executed by Holder and the assignee, the Company shall, without charge, execute
and deliver a new Warrant in the name of the assignee named in such instrument
of assignment, this Warrant shall promptly be canceled and such assignee shall
be deemed to be the Holder of this Warrant. This Warrant may be divided or
combined with any other Warrants which carry the same rights upon presentation
thereof at the office of the Company, together with a written notice specifying
the names and denominations in which new Warrants are to be issued and signed by
the Holder hereof. The term "WARRANT" as used herein includes any Warrants into
or for which this Warrant may be divided or exchanged. Upon receipt by the
Company of evidence satisfactory to it of the loss, theft, destruction or
mutilation of this Warrant, and, in the case of loss, theft or destruction, of
reasonably satisfactory indemnification, and upon surrender and cancellation of
this Warrant, if mutilated, the Company will execute and deliver a new Warrant
of like tenor and date.

5.       RIGHTS OF HOLDER. Holder shall not, by virtue hereof, be entitled to
any rights of a shareholder in the Company, either at law or equity, and the
rights of Holder are limited to those expressed in this Warrant and are not

<PAGE>

enforceable against the Company except to the extent set forth herein.
Notwithstanding the foregoing, (a) with respect to any transaction involving
self-dealing or conflict of interest on the part of the Company's directors or
controlling shareholders, Holder shall be a beneficiary of and entitled to the
same fiduciary duties that may be owed, from time to time, by the Company's
board of directors and controlling shareholders to the holders of shares of its
Common Stock, and (b) the Company will transmit to Holder such information,
documents and reports as are generally distributed to the holders of any class
or series of the securities of the Company concurrently with the distribution
thereof to the shareholders.

6.       ANTI-DILUTION PROVISIONS. The Exercise Price and the number and kind of
securities purchasable upon the exercise of this Warrant shall be subject to
adjustment from time to time upon the happening of certain events as hereinafter
provided. The Exercise Price in effect at any time and the number and kind of
securities purchasable upon exercise of each Warrant shall be subject to
adjustment as follows:

         (a) In case the Company shall (i) pay a dividend or make a distribution
on its shares of Common Stock in shares of Common Stock, (ii) subdivide or
reclassify its outstanding Common Stock into a greater number of shares, or
(iii) combine or reclassify its outstanding Common Stock into a smaller number
of shares, the Exercise Price and the number of shares purchasable upon further
exercise of this Warrant in effect at the time of the record date for such
dividend or distribution or of the effective date of such subdivision,
combination or reclassification shall be proportionately adjusted so that, by
exercising the Warrant after such date Holder shall be entitled to receive the
same number of shares which, if such Warrant had been exercised immediately
prior to such date, it would have received upon such exercise immediately
followed by such event. For example, if there should be a 2-for-1 stock split of
the Common Stock, the Exercise Price shall be divided by two and the number of
shares purchasable upon further exercise of this Warrant shall be doubled. Such
an adjustment shall be made successively whenever any event listed above shall
occur. Notwithstanding the foregoing, if there is a reverse split of the
outstanding Common Stock into a smaller number of shares during the first twelve
(12) months after the date of this Agreement, the number of shares which may be
purchased on exercise of this Warrant shall be reduced as provided in this
paragraph, but the exercise price, only with respect to the first such reverse
split, shall only be increased by 50% of the proportionate adjustment.

         (b) Excluding any transaction covered by Section 6(a), (i) in case of
any reclassification, capital reorganization or other change of outstanding
shares of Common Stock of the Company, or in case of any consolidation or merger
of the Company with or into another entity (other than a merger in which the
Company is the continuing entity and which does not result in any
reclassification, capital reorganization or other change of outstanding shares
issuable upon exercise of this Warrant), or (ii) in case of any sale or other
conveyance (or series of related sales or conveyances) of all or substantially
all of the property of the Company to another party or other parties, the
Company shall, as a condition precedent to such transaction, cause effective
provisions to be made so that Holder shall have the right thereafter by
exercising this Warrant to purchase the kind and amount of shares of stock and
other securities and property receivable upon such reclassification, capital
reorganization and other change, consolidation, merger, sale or conveyance by a
holder of the number of shares of Common Stock which might have been received
upon exercise of this Warrant followed immediately by such reclassification,
change, consolidation, merger, sale or conveyance. Any such provision shall
include provision for adjustments which shall be as nearly equivalent as may be
practicable to the adjustments provided for in this Warrant. The foregoing
provisions of this Section (c) shall similarly apply to successive
reclassifications, capital reorganizations and changes of shares of Common Stock
and to successive consolidations, mergers, sales or conveyances.

         (c) Whenever the Exercise Price or number or type of shares purchasable
upon exercise of this Warrant is adjusted, as herein provided, the Company shall
promptly cause a notice setting forth the adjusted Exercise Price and adjusted
number of shares issuable upon exercise of this Warrant to be mailed to Holder,
at its last address appearing in the records of the Company.

         (d) In the event that at any time, as a result of an adjustment made
pursuant to the provisions herein, Holder of this Warrant thereafter shall
become entitled to receive any shares of the Company, other than Common Stock,
thereafter the number of such other shares so receivable upon exercise of this
Warrant shall be subject to adjustment from time to time in a manner and on
terms as nearly equivalent as practicable to the provisions with respect to the
Common Stock contained in this Section 6.

<PAGE>

         (e) Irrespective of any adjustments in the Exercise Price or the number
or kind of shares purchasable upon exercise of this Warrant, the Warrant
certificate theretofore or thereafter issued may continue to express the same
price and number and kind of shares as are stated in the Warrant certificate
previously issued pursuant to this Agreement.

7.       NOTICES TO WARRANT HOLDERS. So long as this Warrant shall be
outstanding, if (i) the Company shall pay any dividend or make any distribution
upon the Common Stock, or (ii) if any capital reorganization of the Company,
reclassification of the capital stock of the Company, consolidation or merger of
the Company with or into another corporation, sale, lease or transfer of all or
substantially all of the property and assets of the Company to another
corporation, or voluntary or involuntary dissolution, liquidation or winding up
of the Company shall be effected, or if (iii) there is any sale by the Company
of shares constituting after such sale a majority of its outstanding shares,
then in any such case the Company shall give to Holder, at least thirty (30)
days prior to the earliest date specified in (a) or (b) below, as the case may
be, a written notice containing a brief description of the proposed transaction
and stating (a) the date on which a record date is to be taken for the purpose
of such dividend or distribution, or (b) the date on which such
reclassification, reorganization, consolidation, merger, sale, lease, transfer,
dissolution, liquidation or winding up is to take place and the date, if any, to
be fixed as of which the holders of Common Stock or other securities shall
receive cash or other property deliverable upon such transaction.

8.       RESTRICTIONS ON TRANSFERS AND COMPLIANCE WITH SECURITIES LAWS

         (a) This Warrant and the Warrant Shares have not been registered under
the Securities Act of 1933, as amended (the "Federal Act"), and have not been
qualified under the California Corporate Securities Law of 1968, as amended (the
"California Law"). In not so registering or qualifying this Warrant, the Company
is relying on the exemption from the registration requirements under the Federal
Act provided by 506 of Regulation D under that Act, and on the exemption from
the qualification requirements under the California Law provided by Section
18(b)(4)(D) of the Federal Act, and on Holder's representations set forth below
in this Section 8.

         (b) Holder agrees that it will not sell, pledge or otherwise transfer
any or all of this Warrant if such transaction would be in violation, or would
cause the Company to violate, the Federal Act or the California Law. As a
condition to any such sale, pledge or transfer of this Warrant, Holder will give
the Company written notice of such transaction and a written agreement by the
proposed purchaser, pledgee or transferee to be bound by the restrictions set
forth in this Section 8 and the other terms of this Warrant.

         (c) The Company will endeavor to comply with all such applicable
security law requirements in connection with the exercise of this Warrant, but,
except as provided in Exhibit A, shall not be required to register or qualify
this Warrant or the Warrant Shares under the Federal Act, the California Law or
any other state securities law. Subject to Exhibit A, the Company shall be
entitled to utilize applicable exemptions from the registration requirements
under state and federal securities laws, even though such exemptions entail
restrictions on the transferability of Warrant Shares. A legend comparable to
the legend at the beginning of this Warrant shall be placed on all certificates
representing Warrant Shares unless or until there is provided to the Company an
opinion of counsel or other reasonable evidence that such legend is not or is no
longer required.

         (d) Holder represents and warrants that this Warrant has been acquired
for its own account and not with a view to the sale or other disposition of this
Warrant or any shares issuable upon exercise of this Warrant in connection with
any distribution thereof, subject to Holder's rights immediately to sell or
dispose of any Warrant Shares registered under the Federal Act pursuant to
Exhibit A.

         (e) In addition to the foregoing restrictions, this Warrant, or any
portion of this Warrant, shall not be transferable to or exercisable by any
person or entity other than Holder, the present sole shareholders of Holder, an
estate planning grantor trust for the benefit of such shareholders' children of
which such shareholders are the sole trustees and, following either such
shareholder's death, his or her estate or legal successors in interest.

9.       RESERVATION OF SHARES. The Company hereby agrees that at all times
there shall be reserved for issuance and/or delivery upon exercise of this
Warrant such number of shares of its Common Stock as shall be required for

<PAGE>

issuance and delivery upon exercise of this Warrant. All shares issued upon
proper exercise of this Warrant shall be validly issued, fully paid and
nonassessable.

10.      WARRANTIES AND AGREEMENTS BY HOLDER

         In connection with its purchase of this Warrant, Holder warrants and
represents to the Company and agrees as follows:

         (a) In making this investment, Holder is relying upon its own
investigation and analysis and has determined that the Warrant is a suitable
investment for it. The Company has made available to Holder the opportunity to
question its officers concerning the terms of this offering and the proposed
activities of the Company and Holder has been furnished with all such
information which it has requested. Holder is aware that the purchase of this
Warrant is an illiquid investment. It has never been guaranteed or warranted by
the Company's management, or any person connected with or acting on the
Company's behalf, that Holder will be able to sell or liquidate this Warrant or
the Warrant Shares in any specified period of time or that there will be any
profit to be realized as a result of this investment. Holder has adequate means
to provide for its current and expected financial needs and reasonable
contingencies, and can bear the economic risks associated with this investment.

         (b) Holder represents that it has a substantial preexisting personal or
business relationship with the Company's officers or directors, and is, by
reason of its owners' business or financial experience, capable of evaluating
the merits and risks of its purchase of this Warrant and has the capacity to
protect its interests in connection with this investment. In addition, with
respect to Holder's sole shareholders, Robert and Carol Ludovise:

                  (i) their joint net worth, including the estimated net fair
market value of their principal residence, presently exceeds $1,000,000; and/or

                  (ii) they had income in excess of $300,000 in each of the two
most recent years and reasonably expect to have income in excess of $300,000 in
the current year.

         (c) This Warrant Agreement and the Services Agreement have been duly
authorized and executed by Holder and are valid and binding obligations of
Holder, enforceable against Holder in accordance with their terms, subject to
applicable bankruptcy, insolvency or other laws of general application affecting
the enforcement of creditors' rights.

         (d) Holder is not a party to, bound by or subject to any agreement or
instrument, or any judgment, order or decree of any court or governmental agency
or authority, or any law or regulation, which would be violated by its entering
into or carrying out this Warrant Agreement or the Services Agreement.

         (e) The execution and delivery of this Warrant Agreement and the
Services Agreement by Holder will not conflict with or breach any provision of
Holder's Articles of Incorporation or Bylaws or any agreement to which Holder is
a party.

                                RIGHTS OF HOLDER

1.       DEFINITIONS

         In addition to the definitions contained in the Warrant Agreement, as
used in this Exhibit A the following terms shall have the following respective
meanings:

         (a) "Commission" shall mean the Securities and Exchange Commission or
any other federal agency at the time administering the Securities Act.

         (b) "Company" shall mean thehealthchannel.com, Inc., a Delaware
corporation.

         (c) "Exchange Act" shall mean the Securities Exchange Act of 1934, as
amended, or any similar federal statute and the rules and regulations of the
Commission thereunder, all as the same shall be in effect at the time.

         (d) "Holder" shall mean Institute for Medical Studies, Inc. and any
person to whom all or a portion of this Warrant is transferred under Section 8
of the Warrant Agreement.

         (e) "Recapitalizations" shall mean stock splits, stock dividends,
exchanges of shares of the Company for other shares of the Company and the like
affecting outstanding shares of the Company.

         (f) "Registrable Securities" means (i) the Shares; and (ii) any Common
Stock of the Company issued or issuable in respect of the Shares or other
securities issued or issuable pursuant to the exercise of this Warrant upon any
Recapitalization, or any Common Stock otherwise issued or issuable with respect
to this Warrant; Provided, however, that shares of Common Stock or other
securities shall only be treated as Registrable Securities if and so long as

public distribution or a public securities transaction, or (B) have not been

         (a) NOTICE OF REGISTRATION. If at any time or from time to time the
Company shall determine to register any of its securities, either for its own
account or the account of a security holder or holders, including (without
limitation) any registration of the Company's shares issued to shareholders of
Biologix International Ltd., but excluding any registration relating solely to

                  (ii) include in such registration (and any related
qualification under blue sky laws or other compliance), and in any underwriting
involved therein, all the Registrable Securities specified in a written request
or requests, made within 20 days after receipt of such written notice from the

         (b) UNDERWRITING. If the registration of which the Company gives notice
is for a registered public offering involving an underwriting, the Company shall
so advise each Holder as a part of the written notice given pursuant to Section
2(a)(i). In such event the right of any Holder to registration pursuant to this
Section 2 shall be conditioned upon such Holder's participation in such

withdraw therefrom by written notice to the Company and the managing
underwriter. Any securities excluded or withdrawn from such underwriting shall

distribution prior to 90 days after the effective date of the registration
statement relating thereto, or such other shorter period of time as the
underwriters may require. The Company may include shares of Common Stock held by

includible in such registration statement would not thereby be diminished.

         (c) RIGHT TO TERMINATE REGISTRATION. The Company shall have the right
to terminate or withdraw any registration initiated by it under this Section 2
prior to the effectiveness of such registration whether or not any Holder has
elected to include securities in such registration.

required in connection with any registration, qualification or compliance
referred to in this Exhibit A.

7.       INDEMNIFICATION

         (a) The Company will indemnify each Holder, each of its officers,

each underwriter, if any, and each person who controls any underwriter within
the meaning of Section 15 of the Securities Act, against all expenses, claims,
losses, damages or liabilities (or actions in respect thereof), including any of
the foregoing incurred in settlement of any litigation, commenced or threatened,

a material fact contained in any registration statement, prospectus, offering
circular or other document, or any amendment or supplement

<PAGE>

thereto, incident to any such registration, qualification or compliance, or
based on any omission (or alleged omission) to state therein a material fact
required to be stated therein or necessary to make the statements therein, in
light of the circumstances in which they were made, not misleading, or any
violation by the Company of the Securities Act or any rule or regulation
promulgated under the Securities Act applicable to the Company in connection
with any such registration, qualification or compliance, and the Company will
reimburse each such Holder, each of its officers and directors, and each person
controlling such Holder, each such underwriter and each person who controls any
such underwriter, for any legal and any other expenses reasonably incurred in
connection with investigating, preparing or defending any such claim, loss,
damage, liability or action, provided that the Company will not be liable in any
such case to the extent that any such claim, loss, damage, liability or expense
arises out of or is based on any untrue statement or omission or alleged untrue
statement or omission, made in reliance upon and in conformity with written
information furnished to the Company by an instrument duly executed by such
Holder, controlling person or underwriter and stated to be specifically for use
therein.

         (b) Each Holder will, if Registrable Securities held by such Holder are
included in the securities as to which such registration, qualification or
compliance is being effected, indemnify the Company, each of its directors and
officers, each underwriter, if any, of the Company's securities covered by such
a registration statement, each person who controls the Company or such
underwriter within the meaning of Section 15 of the Securities Act, and each
other such Holder, each of its officers and directors and each person

prospectus, offering circular or other document, or any omission (or alleged
omission) to state therein a material fact required to be stated therein or

omission) is made in such registration statement, prospectus, offering circular
or other document in reliance upon and in conformity with written information
furnished to the Company by an instrument duly executed by such Holder and
stated to be specifically for use therein. Notwithstanding the foregoing, the
liability of each Holder under this subsection (b) shall be limited to an amount

Holder.

         (c) Each party entitled to indemnification under this Section 7 (the
"Indemnified Party") shall give notice to the party required to provide
indemnification (the "INDEMNIFYING PARTY") promptly after such Indemnified Party
has actual knowledge of any claim as to which indemnity may be sought, and shall
permit the Indemnifying Party to assume the defense of any such claim or any
litigation resulting therefrom, provided that counsel for the Indemnifying
Party, who shall conduct the defense of such claim or litigation, shall be
approved by the Indemnified Party (whose approval shall not unreasonably be
withheld), and the Indemnified Party may participate in such defense at such
party's expense, and provided further that the failure of any Indemnified Party
to give notice as provided herein shall not relieve the Indemnifying Party of
its obligations under this Exhibit A unless the failure to give such notice is
materially prejudicial to an Indemnifying Party's ability to defend such action
and provided further, that the Indemnifying Party shall not assume the defense
for matters as to which there is a conflict of interest or separate and
different defenses. No Indemnifying Party, in the defense of any such claim or
litigation, shall, except with the consent of each Indemnified Party, consent to

unconditional term thereof the giving by the claimant or plaintiff to such
Indemnified Party of a release from all liability in respect to such claim or
litigation.

                        (AS AMENDED THROUGH MAY 19, 1999)
                        ---------------------------------

1. PURPOSE

The purpose of this Employee Share Option Plan (the "Plan") of Visible Genetics
Inc., an Ontario corporation (the "Company"), is to provide an incentive to
officers, consultants and key employees of the Company and its affiliates by
providing them with the opportunity, through share options, to acquire an
increased proprietary interest in the Company.

2. ADMINISTRATION

The Compensation Committee of the Company's Board of Directors (the "Directors")
shall supervise and administer the Plan.

3. GRANTING OF OPTIONS

The Directors may from time to time by resolution designate persons who are
officers, consultants or key employees of the Company or any of its affiliates
(the "Optionees") to whom options to purchase common shares of the Company (the
"Common Shares") may be granted and the number of the Common Shares to be
optioned to each of them, provided that the total number of Common Shares to be
optioned under this Plan shall not exceed the number provided for in Section 4
hereof. Options shall be granted for a period of up to ten (10) years from the
date, in each case, of the grant, and otherwise upon and subject to such terms,
conditions, limitations, prohibitions and restrictions as are herein contained,
and the said number of authorized and unissued Common Shares (subject to
adjustment pursuant to the provisions of Section 8 hereof) be and they are
hereby set aside and reserved for allotment for the purpose of this Plan.

The Directors may, in their discretion, require as conditions to the grant or
exercise of any option that the Optionee shall have:

     a)   Represented, warranted and agreed in form and substance satisfactory
          to the Company that the Optionee is acquiring and will acquire such
          option and the Common Shares to be issued upon exercise thereof or, as
          the case may be, is acquiring such Common Shares, for the Optionee's
          own account for investment and not with a view to or in connection
          with any distribution, that the Optionee has access to such
          information as is necessary to enable the Optionee to evaluate the
          merits and risks of such investment and that the Optionee is able to
          bear the economic risk of holding such Common Shares for an indefinite
          period;

     b)   Agreed to restrictions on transfer in form and substance satisfactory
          to the Company and to an endorsement on the option or certificate
          representing the Common Shares making appropriate reference to such
          restrictions; and

                                      A-1

<PAGE>

     c)   Agreed to indemnify the Company in connection with the foregoing.

In addition, any option granted under this Plan shall be subject to the
requirement that, if at any time counsel to the Company shall determine that the
listing, registration or qualification of the Common Shares subject to such
option upon any securities exchange or under any law or regulation of any
jurisdiction, or the consent or approval of any securities exchange or any
governmental or regulatory body, is necessary as a condition of, or in
connection with, the grant or exercise of such option or the issuance or
purchase of Common Shares hereunder, such option may not be accepted or
exercised in whole or in part unless such listing, registration, qualification,
consent or approval shall have been effected or obtained on conditions
acceptable to the Directors. Nothing herein shall be deemed to require the
Company to apply for or to obtain such listing, registration, qualification,
consent or approval.

this Plan, subject to adjustment or increase of such number pursuant to the
provisions of Section 8 hereof, is 1,500,000 Common Shares. In addition, the
aggregate number of Common Shares reserved for issuance under all options
granted to any one Optionee, whether granted pursuant to a plan or any other
option right or share purchase right (whether granted pursuant to a plan or
otherwise) granted by the Company and outstanding at such time, shall not exceed
the number of Common Shares permitted to be so reserved to such Optionee by law
and by the regulations, rules or policies of the several securities authorities
and stock exchanges to which the Company is on the relevant date subject.

Common Shares in respect of which options are not exercised shall be available
for options subsequently granted. No fractional Common Shares may be purchased
under this Plan.

Each option granted under the Plan shall be evidenced by a written agreement in
such form as the Directors shall from time to time approve, which agreements
shall comply with and be subject to the following terms and conditions:

     a)   OPTION EXERCISE PRICE. The option exercise price per Common Share for
          each option granted under the Plan shall be as determined by the
          Directors, provided that such price shall not be less than the current
          market price of the Common Shares on the date of the grant. For the
          purposes hereof, the term "current market price" shall mean the
          current market price as determined in good faith by the Directors.

     b)   OPTIONS NON-TRANSFERABLE. Each option granted under the Plan by its
          terms shall not be transferable by the optionee otherwise than by
          will, or by the laws of descent and distribution, or pursuant to a
          qualified domestic relations order (as defined in Section 414(p) of
          the United states Internal Revenue Code (the

                                      A-2
<PAGE>

          "Code")), and shall be exercised during the lifetime of the optionee
          only by him. No option or interest therein may be transferred,
          assigned, pledged or hypothecated by the optionee during his lifetime,
          whether by operation of law or otherwise, or be made subject to
          execution, attachment or similar process.

     c)   EXERCISE PERIOD. Except as otherwise provided in the plan, each option
          may be exercised fully on the date of grant of such option, provided
          that, subject to the provisions of Section 5(d), no option may be
          exercised more than ninety (90) days after the optionee ceases to
          serve as an employee or consultant of the Company. No option shall be
          exercisable after the expiration of ten (10) years from the date of
          grant or prior to approval of the Plan by the shareholders of the
          Company, whichever is earlier.

     d)   EXERCISE PERIOD UPON DISABILITY OR DEATH. Notwithstanding the
          provisions of Section 5(c), any option granted under the Plan:

               (i)  may be exercised in full by an optionee who becomes disabled
                    (within the meaning of Section 22(e)(3) of the Code or any
                    successor provision thereof) while serving as an employee or
                    consultant of the Company; or

               (ii) may be exercised:

                    (A)  in full upon the death of an optionee while serving as
                         an employee or consultant of the Company, or

                    (B)  to the extent when exercisable upon the death of an
                         optionee within ninety (90) days of ceasing to serve as
                         an employee or consultant of the Company,

               by   the person to whom it is transferred by will, by the laws of
                    descent and distribution, or by written notice filed
                    pursuant to Section 5(g);

                  in each such case within the period of one year after the date
                  the optionee ceases to be such an employee or consultant;
                  provided, that no option shall be exercisable after the
                  expiration of ten (10) years from the date of grant.

     (e)  EXERCISE PROCEDURE. Options may be exercised only by written notice to
          the Company at its principal office accompanied by payment of the full
          consideration for the Common Shares as to which they are exercised.

     (f)  PAYMENT OF PURCHASE PRICE. Options granted under the Plan may
          provide for the payment of the exercise price (i) by delivery of
          cash or a check to the order of the Company in an amount equal to
          the exercise price of such options or, (ii) to the extent provided
          in the applicable option agreement, by delivery to the Company of
          Common Shares then owned by the optionee having a fair market value
          equal

                                      A-3
<PAGE>

          in amount to the exercise price of the Options being exercised, or
          (iii) by any combination of such methods of payment. The fair market
          value of any Common Shares or other non-cash consideration which may
          be delivered upon exercise of an option shall be determined by the
          Directors.

     (g)  EXERCISE OF REPRESENTATIVE FOLLOWING DEATH OF DIRECTOR. A Director, by
          written notice to the Company, may designate one or more persons (and
          from time to time change such designation) including his legal
          representative, who, by reason of his death, shall acquire the right
          to exercise all or a portion of the option. If the person or persons
          so designated wish to exercise any portion of the option, they must do
          so within the term of the option as provided herein. Any exercise by a
          representative shall be subject to the provisions of the Plan.

6. ASSIGNMENTS

The rights and benefits under the Plan may not be assigned except for the
designation of a beneficiary as provided in Section 5.

7. LIMITATION OF RIGHTS

     (a)  NO RIGHT TO CONTINUE AS AN EMPLOYEE OR CONSULTANT. Neither the Plan
          nor the granting of an option nor any other action taken pursuant to
          the Plan, shall constitute or be evidence of any agreement or
          understanding, express or implied, that the Company will retain an
          employee or consultant for any period of time.

     (b)  NO SHAREHOLDERS' RIGHTS FOR OPTIONS. An optionee shall have no rights
          as a shareholder with respect to the Common Shares covered by his
          options until the date of the issuance to him of a share certificate
          therefor, and no adjustment will be made for dividends or other rights
          for which the record date is prior to the date such certificate is
          issued.

8. CHANGES IN CAPITAL STOCK

          decreased or exchanged for a different number or kind of share or
          other security of Company, or (y) additional shares of Common
          Shares or new or different shares of Common Shares or other
          securities of the Company or other non-cash assets are distributed
          with respect to such shares or other securities, through or as a
          result of any merger, consolidation, sale of all or substantially
          all of the assets of the Company, reorganization, recapitalization,
          reclassification, stock dividend, stock split, reverse stock split

          other securities subject to then outstanding options under the Plan
          and (iii) the price of each share subject to any then outstanding
          options under the Plan, without changing the aggregate purchase

                                      A-4

          price as to which such options remain exercisable. No fractional
          shares will be issued under the Plan on account of any such
          adjustments. Notwithstanding the foregoing, no adjustment shall be
          made pursuant to this Section 8 if such adjustment would cause the
          Plan to fail to comply with Rule 16b-3 or any successor rule
          promulgated pursuant to Section 16 of the Securities Exchange Act of
          1934.

     (b)  In the event that the Company is merged or consolidated into or with
          another corporation (in which consolidation or merger, the
          shareholders of the Company receive distributions of cash or
          securities of another issuer as a result thereof), or in the event
          that all or substantially all of the assets of the Company are
          acquired by any other person or entity, or in the event of a
          reorganization or liquidation of the Company, the Directors of the
          Company, or the board of directors of any corporation assuming the
          obligations of the Company, shall, as to outstanding options take one
          or more of the following actions: (i) provide that such options shall
          be assumed, or equivalent options shall be substituted, by the
          acquiring or succeeding corporation (or an affiliate thereof), (ii)
          upon written notice to the optionee, provide that all unexercised
          options will terminate immediately prior to the consummation of such
          transaction unless exercised by the optionee within a specified period
          following the date of such notice, or (iii) if, under the terms of a
          merger transaction, holders of the Common Shares of the Company will
          receive upon consummation thereof a cash payment for each share
          surrendered in the merger (the "Merger Price"), make or provide for a
          cash payment to the optionees equal to the difference between (A) the
          Merger Price times the number of shares of Common Shares subject to
          such outstanding options (to the extent then exercisable at prices not
          in excess of the Merger Price) and (B) the aggregate exercise price of
          all such outstanding options in exchange for the termination of such
          options.

9. AMENDMENT OF THE PLAN

The Directors may suspend or discontinue the Plan or review or amend it in any
respect whatsoever; provided, however, that without approval of the shareholders
of the Company no revision or amendment shall change the number of shares
subject to the Plan or the number of shares issuable to any shareholder of the
Company under the Plan (except as provided in Section 8), change the designation
of the class of persons eligible to receive options, or materially increase the
benefits accruing to participants under the Plan.

10. WITHHOLDING

The Company shall have the right to deduct from payments of any kind otherwise
due to the optionee, any federal, state or local taxes of any kind required by
law to be withheld with respect to any shares issued upon exercise of options
under the Plan.

11. EFFECTIVE DATE AND DURATION OF THIS PLAN

     (a)  EFFECTIVE DATE. The Plan shall become effective when adopted by the
          Directors and approved by the Company's shareholders. Amendments to
          the plan not requiring shareholder approval shall become effective
          when adopted by the Directors; amendments requiring shareholder
          approval shall become effective when adopted by the Directors, but no
          option granted after the date of such amendment shall become
          exercisable (to the extent that such amendment to the Plan was
          required to enable the Company to grant such option to a particular
          optionee) unless and until such amendment shall have been approved by
          the Company's shareholders. If such shareholder approval is not
          obtained within twelve months of the Board's adoption of such
          amendment, any options granted on or after the date of such amendment
          shall terminate to the extent that such amendment to the Plan was
          required to enable the Company to grant such option to a particular
          optionee.

     (b)  TERMINATION. Unless sooner terminated by the Directors, the Plan shall
          terminate upon the date on which all shares available for issuance
          under the Plan shall have been issued pursuant to the exercise or
          cancellation of options granted under the Plan.

Any written notice to the Company required by any of the provisions of the Plan
shall be addressed to the Secretary of the Company and shall become effective
when it is received.

13. GOVERNMENTAL REGULATION

The Company's obligation to sell and deliver shares of Common Shares under the
plan is subject to the approval of or requirements of any governmental authority
applicable in connection with the authorization, issuance or sale of such
shares.

14. COMPLIANCE WITH RULE 16b-3

Transactions under the Plan are intended to comply with all applicable
conditions of Rule 16b-3 or its successor promulgated pursuant to Section 16 of

action by the Directors in administering the plan fails to so comply, it shall
be deemed null and void, to the extent permitted by law and deemed advisable by
the Directors.

The Plan and all determinations made and actions taken pursuant hereto shall be
governed by the laws of the Province of Ontario and the laws of Canada
applicable therein.

16. SUCCESSORS AND ASSIGNS

This Plan shall inure to the benefit of and be binding upon each successor and
assign of the Company. All obligations imposed upon an optionee, and all rights
granted to the Company hereunder, shall be binding upon the optionee's heirs,
legal representatives and successors.

17. ENTIRE AGREEMENT

This Plan and the written agreement with respect to each option granted under
this Plan constitute the entire agreement with respect to the subject matter
hereof and thereof, provided that in the event of any inconsistency between the
Plan and such written agreement, the terms and conditions of this Plan shall
control.

18. INCENTIVE STOCK OPTIONS

Notwithstanding anything in the Plan to the contrary, options granted under the
Plan which are intended to be "Incentive Stock Options" within the meaning of
Section 422 of the Code shall be subject to the following additional terms and
conditions:

     (a)  EXPRESS DESIGNATION. All Incentive Stock Options granted under the
          Plan shall, at the time of grant, be specifically designated as such
          in the written agreement evidencing such Incentive Stock Options.
          Incentive Stock Options may be granted only to persons who are, at the
          time of grant, employees of the Company or any parent or subsidiary of
          the Company as respectively defined in Sections 424(e) and 424(f) of
          the Code (an "Affiliate"). No Incentive Stock Option may be granted
          hereunder more than ten (10) years from the earlier of (i) the date
          the Plan was adopted, or (ii) the date the Plan was approved by the
          shareholders of the Company.

     (b)  EXERCISE PRICE. The option exercise price per Common Share subject to
          each Incentive Stock Option granted under the Plan shall not be less
          than 100% of the fair market value of a Common Share at the time of
          grant of such option. For purposes of the Plan, the fair market value
          of a Common Share as of a specified date shall be determined in good
          faith by the Directors. In no case shall the fair market value of a
          Common Share be determined with regard to restrictions other than
          restrictions which, by their terms, will never lapse.

     (c)  10% SHAREHOLDER. Notwithstanding the foregoing, if any employee to
          whom an Incentive Stock Option is to be granted under the Plan is, at
          the time of the grant of such option, the owner of stock possessing
          more than 10% of the total combined voting power of all classes of
          stock of the Company (after taking into account the attribution of
          stock ownership rules of Section 424(d) of the Code), then the
          following special provisions shall be applicable to the Incentive
          Stock Option granted to such individual:

                                      A-7

<PAGE>

               (i)  the option exercise price per Common Share subject to such
                    Incentive Stock Option shall not be less than 110% of the
                    fair market value of a Common Share at the time of grant;
                    and

               (ii) the option exercise period shall not exceed five (5) years
                    from the date of grant.

     (d)  DOLLAR LIMITATION. For so long as the Code shall so provide, options
          granted to any employee under the Plan (and any other Incentive Stock
          Option plans of the Company) which are intended to constitute
          Incentive Stock Options shall not constitute Incentive Stock Options
          to the extent that such options, in the aggregate, become exercisable
          for the first time in any one calendar year for Common Shares with an
          aggregate fair market value, as of the respective date or dates of
          grant, of more than $100,000.

     (e)  EXERCISABILITY, TERMINATION OF EMPLOYMENT, DEATH AND DISABILITY. No
          Incentive Stock Option may be exercised unless, at the time of such
          exercise, the optionee is, and has been continuously since the date of
          grant of his or her option, employed by the Company or an Affiliate,
          except that:

               (i)  an Incentive Stock Option may be exercised within the period
                    of three (3) months after the date the optionee ceases to be
                    an employee of the Company or an Affiliate (or within such
                    lesser period as may be specified in the acceptable option
                    agreement), to the extent it is otherwise exercisable at the
                    time of such cessation,

               (ii) if the optionee dies while in the employ of the Company or
                    an Affiliate, or within three (3) months after the optionee
                    ceases to be such an employee, the Incentive Stock Option
                    may be exercised by the person to whom it is transferred by
                    will or the laws of descent and distribution within the
                    period of one (1) year after the date of death (or within
                    such lesser period as may be specified in the applicable
                    option agreement), to the extent it is otherwise exercisable
                    at the time of the optionee's death, and

               (iii) if the optionee becomes disabled (within the meaning of
                    Section 22(e)(3) of the Code or any successor provisions
                    thereto) while in the employ of the Company or an Affiliate,
                    the Incentive Stock Option may be exercised within the
                    period of one (1) year after the date the optionee ceases to
                    be such an employee because of such disability (or within
                    such lesser period as may be specified in the applicable
                    option agreement), to the extent it is otherwise exercisable
                    at the time of such cessation.

          For purposes of any Incentive Stock Option granted hereunder,
          "employment" shall be defined in accordance with the provisions of
          Section 1.421-7(h) of the

                                      A-8
<PAGE>

          U.S. Income Tax Regulations (or any successor regulations).
          Notwithstanding the foregoing provisions, no Incentive Stock Option
          may be exercised after the earlier of (1) its expiration date, or (2)
          the tenth anniversary of the date of which the Incentive Stock Options
          is granted.

     (f)  TRANSFER, ASSIGNMENT. No Incentive Stock Option granted under this
          Plan shall be assignable or otherwise transferable by the optionee,
          except by will or by the laws of descent and distribution. An
          Incentive Stock Option may be exercised during the lifetime of the
          optionee only by the optionee.
