ITEM 14 (FORM F-1)/ITEM 15 (FORM F-3).  INDEMNIFICATION OF DIRECTORS AND
OFFICERS
 
     Except as hereinafter set forth, there is no charter provision, by-law,
contract, arrangement or statute under which any director or officer of either
of the Registrants is insured or indemnified in any manner against any liability
which he may incur in his capacity as such.
 
     With respect to Intelligent Polymers:
 
     Intelligent Polymers' Bye-Laws provide that Intelligent Polymers shall
indemnify out of the funds of Intelligent Polymers, except as set forth below,
every director and officer of Intelligent Polymers and every member of a
committee of the Board of Directors of Intelligent Polymers, against all civil
liabilities, loss, damage or expense (including but not limited to liabilities
under contract, tort and statute or any applicable foreign law or regulation and
all reasonable legal and other costs and expenses properly payable) incurred or
suffered by him as such director, officer or committee member and any person
acting as a director, officer or committee member in the reasonable belief that
he has been so appointed or elected notwithstanding any defect in such
appointment or election provided always that the indemnity contained by the
Bye-Laws shall not extend to any matter in respect of any fraud or dishonesty
which may attach to any of the foregoing persons. To the extent that any
director, officer or member of a committee duly constituted under the Bye-Laws
is entitled to claim an indemnity pursuant to the Bye-Laws in respect of amounts
paid or discharged by him, the relative indemnity shall take effect as an
obligation of Intelligent Polymers to reimburse the person making such payment
or effecting such discharge. No director, secretary or other duly appointed
officer of Intelligent Polymers shall be personally liable to Intelligent
Polymers or its shareholders for monetary damages in respect of the exercise or
non-exercise of any power or duty vested in such director, secretary or officer,
provided, however, the foregoing shall not extend to any matter in respect of
any fraud or dishonesty which may attach to any of the foregoing persons.
Expenses incurred in defending a civil or criminal action, suit or proceeding
shall be paid by Intelligent Polymers in advance of the final disposition of
such action, suit or proceeding as authorized by the Board of Directors of
Intelligent Polymers upon receipt of an undertaking by or on behalf of a
director, officer, liquidator or trustee to repay such amount, unless it shall
be ultimately determined that he is entitled to be indemnified by Intelligent
Polymers as authorized in the Bye-Laws or otherwise pursuant to applicable laws.
 
                                      II-1
<PAGE>   3
 
     With respect to Biovail:
 
     Section 6.04 of By-Law No. 1 of Biovail provides as follows:
 
     Subject to the limitations contained in statutory law, Biovail shall
indemnify a director or officer, a former director or officer, or a person who
acts or acted at Biovail's request as a director or officer of a body corporate
of which Biovail is or was a shareholder or creditor, and his heirs and legal
representatives, against all costs, charges and expenses, including an amount
paid to settle an action or satisfy a judgment, reasonably incurred by him in
respect of any civil, criminal or administrative action or proceeding to which
he is made a party by reason of being or having been a director or officer of
Biovail or such body corporate, if
 
          (a) he acted honestly and in good faith with a view to the best
     interest of Biovail; and
 
          (b) in the case of a criminal or administrative action or proceeding
     that is enforced by a monetary penalty, he had reasonable grounds for
     believing that his conduct was lawful.
 
Biovail shall also indemnify such person in such other circumstances as
statutory law permits or requires.
 
ITEM 15 (FORM F-1).  RECENT SALES OF UNREGISTERED SECURITIES
 
     On July 30, 1997 Intelligent Polymers sold 12,000 Special Shares to Biovail
for an aggregate cash purchase price of $12,000. The Special Shares were issued
without registration under the Securities Act of 1933, as amended, in reliance
upon the exemption provided by Section 4(2) of the Act. No underwriting
commissions were paid in connection with such issuance.

ITEM 17.  UNDERTAKINGS
 
     The undersigned Registrants hereby undertake:
 
     (1)  Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the Registrant pursuant to the provisions described under item 14
above, or otherwise, the Registrant has been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public policy
as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In
the event that a claim for indemnification against such liabilities (other than
the payment by the Registrant of expenses incurred or paid by a director,
officer or controlling person of the Registrant in the successful defense of any
action, suit or proceeding) is asserted by such director, officer or controlling
person in connection with the securities being registered, the Registrant will,
unless in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question of whether
such indemnification by it is against public policy as expressed in the
Securities Act of 1933 and will be governed by the final adjudication of such
issue.
 
     (2)  For the purpose of determining any liability under the Securities Act
of 1933, the information omitted from the form of prospectus filed as part of
this registration statement in reliance upon Rule 430A and contained in a form
of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or
497(h) under the Securities Act shall be deemed to be part of this registration
statement as of the time it was declared effective.
 
     (3)  For the purpose of determining any liability under the Securities Act
of 1933, each post-effective amendment that contains a form of prospectus shall
be deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.
 
     (4)  For purposes of determining any liability under the Securities Act of
1933, each filing of the Registrant's annual report pursuant to section 13(a) or
section 15(d) of the Securities Exchange Act of 1934 (and, where applicable,
each filing of an employee benefit plan's annual report pursuant to section
15(d) of the Securities Exchange Act of 1934) that is incorporated by reference
in the registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.
 
     Intelligent Polymers hereby undertakes to provide to the Underwriters at
the closing specified in the underwriting agreement certificates in such
denominations and registered in such names as required by the Underwriters to
permit prompt delivery to each purchaser.

     277 Park Avenue

Dear Sirs:

     Intelligent Polymers Limited, a Bermuda exempted company ("INTELLIGENT
POLYMERS"), and Biovail Corporation International, a public company
incorporated under the laws of Ontario, Canada ("BIOVAIL" and, together with
Intelligent Polymers, the "COMPANIES"), confirm their respective agreements
with the several underwriters named in Schedule I hereto (the "UNDERWRITERS"),
with respect to (i) the sale by the Companies, and the purchase by the
Underwriters, of ____ units (the "FIRM UNITS"), each composed of one common
share, par value $.01 per share, of Intelligent Polymers ("INTELLIGENT POLYMERS
COMMON SHARES") and   ________ of a warrant (the "WARRANTS") to purchase one
authorized but unissued common share, no par value, of Biovail ("BIOVAIL COMMON
SHARES"), exercisable at any time from

<PAGE>   2

                                      2

October 1, 1999 through September 30, 2002 at an exercise price of $___ per
Biovail Common Shares (subject to certain adjustments as set forth in the
Warrant certificate to be issued as part of the Unit Certificate (as
hereinafter defined)) and (ii) the grant by the Companies to the Underwriters
of the option described in Section 2 hereof to purchase all or any part of
____________________ additional units (the "ADDITIONAL UNITS" and together with
the Firm Units, the "UNITS") to cover over-allotments, if any.  The Intelligent
Polymers Common Shares and the Warrants will be paired for sale as units by
Intelligent Polymers and Biovail and then sold to the Underwriters.

     Each Unit will initially be represented by a certificate representing one
or more Intelligent Polymers Common Shares and one or more Warrants (a "UNIT
CERTIFICATE").  Each Unit will be transferable only as a whole and as described
in the Prospectus (as hereinafter defined) through September 30, 1999, or such
earlier date on which the PURCHASE OPTION (as defined in the Prospectus) is
exercised or expires unexercised, after which date the Warrants and the
Intelligent Polymers Common Shares will trade separately.  The Intelligent
Polymers Common Shares, the Warrants, the Biovail Common Shares and the Units
are more fully described in the Registration Statement (as hereinafter defined)
and the Prospectus.

     SECTION 1.  Registration Statement and Prospectus.  The Companies have
prepared and filed with the Securities and Exchange Commission (the
"Commission") in accordance with the Securities Act of 1933, as amended and the
rules and regulations of the Commission thereunder (the "ACT"), a combined
registration statement (Nos. ________________ and ______ _____________)
including the related prospectus, (a) with respect to Intelligent Polymers, on
Form F-1, relating to the Intelligent Polymers Common Shares comprising a
portion of the Units, and (b) with respect to Biovail, on Form F-3, relating to
the Warrants comprising a portion of the Units.  The registration statement, as
amended at the time it became effective, including the information (if any)
deemed to be part of the registration statement at the time of effectiveness
pursuant to Rule 430A under the Act, is hereinafter referred to as the
"REGISTRATION STATEMENT"; and the prospectus in the form first used to confirm
sales of the Units is hereinafter referred to as the "PROSPECTUS" (including in
the case of all references to the Registration Statement or the Prospectus,
documents incorporated therein by reference).   If the Companies have filed or
are required pursuant to the terms hereof to file a registration statement
pursuant to Rule 462(b) under the Act registering additional units (a "RULE
462(b) REGISTRATION STATEMENT"), then, unless otherwise specified, any
reference herein to the term "Registration Statement" shall be deemed to
include such Rule 462(b) Registration Statement.

     The terms "SUPPLEMENT" and "AMENDMENT" or "AMEND" as used in this
Agreement with respect to the Registration Statement or the Prospectus shall
include all documents subsequently filed by the Companies with the Commission
pursuant to the Securities Exchange Act of 1934, as amended, and the rules and
regulations of the Commission





<PAGE>   3
                                       3

thereunder (collectively, the "EXCHANGE ACT") that are deemed to be
incorporated by reference in the Prospectus.

     SECTION 2 .  Agreements to Sell and Purchase and Lock-Up Agreements.   On
the basis of the representations and warranties contained in this Agreement,
and subject to its terms and conditions, the Companies agree to issue and sell,
and each Underwriter agrees, severally and not jointly, to purchase from the
Companies at a price per Unit of $______ (the "PURCHASE PRICE") the number of
Firm Units set forth opposite the name of such Underwriter in Schedule I
hereto.

     On the basis of the representations and warranties contained in this
Agreement, and subject to its terms and conditions, the Companies agree to
issue and sell the Additional Units and the Underwriters shall have the right
to purchase, severally and not jointly, up to _______ Additional Units from the
Companies at the Purchase Price.  Additional Units may be purchased solely for
the purpose of covering over-allotments made in connection with the offering of
the Firm Units.   The Underwriters may exercise their right to purchase
Additional Units in whole or in part from time to time by giving written notice
thereof to the Companies within 30 days after the date of this Agreement.  You
shall give any such notice on behalf of the Underwriters and such notice shall
specify the aggregate number of Additional Units to be purchased pursuant to
such exercise and the date for payment and delivery thereof, which date shall
be a business day (i) no earlier than two business days after such notice has
been given (and, in any event, no earlier than the Closing Date (as hereinafter
defined)) and (ii) no later than ten business days after such notice has been
given.   If any Additional Units are to be purchased, each Underwriter,
severally and not jointly, agrees to purchase from the Companies the number of
Additional Units (subject to such adjustments to eliminate fractional shares as
you may determine) which bears the same proportion to the total number of
Additional Units to be purchased from the Companies as the number of Firm Units
set forth opposite the name of such Underwriter in Schedule I bears to the
total number of Firm Units.

     Each of Biovail and Intelligent Polymers hereby agree not to (i) offer,
pledge, sell, contract to sell, sell any option or contract to purchase,
purchase any option or contract to sell, grant any option, right or warrant to
purchase, or otherwise transfer or dispose of, directly or indirectly, any
Biovail Common Shares, Intelligent Polymers Common Shares or SPECIAL SHARES (as
defined in the Prospectus) or any securities convertible into or exercisable or
exchangeable for such shares or (ii) enter into any swap or other arrangement
that transfers all or a portion of the economic consequences associated with
the ownership of any Biovail Common Shares, Intelligent Polymers Common Shares
or Special Shares (regardless of whether any of the transactions described in
clause (i) or (ii) is to be settled by the delivery of such common shares, or
such other securities, in cash or otherwise), except to the Underwriters
pursuant to this Agreement, for a period of 180 days after the date of the
Prospectus without your prior written consent.  Notwithstanding the foregoing,
during such period (i) Biovail may grant stock options pursuant to Biovail's
existing stock option plan and





<PAGE>   4
                                       4

(ii) Biovail may issue shares of Biovail Common Shares upon the exercise of an
option or warrant or the conversion of a security outstanding on the date
hereof.  Each of Biovail and Intelligent Polymers also agree not to file any
registration statement with respect to any shares of Biovail Common Shares,
Intelligent Polymers Common Shares or the Special Shares or any securities
convertible into or exercisable or exchangeable for such shares for a period of
180 days after the date of the Prospectus without your prior written consent.
Each of Biovail and Intelligent Polymers shall, prior to or concurrently with
the execution of this Agreement, deliver an agreement executed by certain of
the directors and officers of Biovail and Intelligent Polymers to the effect
that such person will not, during the period commencing on the date such person
signs such agreement and ending 180 days after the date of the Prospectus,
without your prior written consent, (A) engage in any of the transactions
described in the first sentence of this paragraph or (B) make any demand for,
or exercise any right with respect to, the registration of any of Biovail
Common Shares, Intelligent Polymers Common Shares or the Special Shares or any
securities convertible into or exercisable or exchangeable for such shares.

     SECTION 3.  Terms of Public Offering.  The Companies are advised by you
that the Underwriters propose (i) to make a public offering of their respective
portions of the Units as soon after the execution and delivery of this
Agreement as in your judgment is advisable and (ii) initially to offer the
Units upon the terms set forth in the Prospectus.

     SECTION 4.  Delivery and Payment.  Delivery to the Underwriters of and
payment to Intelligent Polymers for the Firm Units shall be made at 9:00 A.M.,
New York City time, on September ____, 1997 (the "CLOSING DATE") at such place
as you shall designate.   The Closing Date and the location of delivery of and
payment for the Firm Units may be varied by agreement between you and the
Companies.

     Delivery to the Underwriters of and payment for any Additional Units to be
purchased by the Underwriters shall be made at such place as you shall
designate at 9:00 A.M., New York City time, on the date specified in the
applicable exercise notice given by you pursuant to Section 2 (an "OPTION
CLOSING DATE").   Any such Option Closing Date and the location of delivery of
and payment for such Additional Shares may be varied by agreement between you
and the Companies.

     Certificates for the Units shall be registered in such names and issued in
such denominations as you shall request in writing not later than two full
business days prior to the Closing Date or an Option Closing Date, as the case
may be.  Such certificates shall be made available to you for inspection not
later than 9:30 A.M., New York City time, on the business day prior to the
Closing Date or the applicable Option Closing Date, as the case may be.
Certificates in definitive form evidencing the Shares shall be delivered to you
on the Closing Date or the applicable Option Closing Date, as the case may be,
with any transfer taxes thereon duly paid by the Company, for the respective
accounts of the several Underwriters,

against payment to the Company of the Purchase Price therefor by wire transfer
of Federal or other funds immediately available in New York City.

     SECTION 5.  Agreements of Biovail and Intelligent Polymers.  The Companies
agree with you that:

     (a)         The Companies will advise you promptly and, if requested by
you, confirm such advice in writing, (i) of any request by the Commission for
amendments to the Registration Statement or amendments or supplements to the
Prospectus or for additional information, (ii) of the issuance by the
Commission of any stop order suspending the effectiveness of the Registration
Statement or of the suspension of qualification of the Units for offering or
sale in any jurisdiction, or the initiation of any proceeding for such
purposes, (iii) when any amendment to the Registration Statement becomes
effective, (iv) if the Companies are required to file a Rule 462(b)
Registration Statement after the effectiveness of this Agreement, when the Rule
462(b) Registration Statement has become effective and (v) of the happening of
any event during the period referred to in Section 5(d) below which makes any
statement of a material fact made in the Registration Statement or the
Prospectus untrue or which requires any additions to or changes in the
Registration Statement or the Prospectus in order to make the statements
therein not misleading.  If at any time the Commission shall issue any stop
order suspending the effectiveness of the Registration Statement, the Companies
will use their respective best efforts to obtain the withdrawal or lifting of
such order at the earliest possible time.

     (b)         The Companies will furnish you four signed copies of the
Registration Statement as first filed with the Commission and of each amendment
to it, including all exhibits and documents incorporated therein by reference,
and furnish to you and each Underwriter designated by you such number of
conformed copies of the Registration Statement as so filed and of each
amendment to it, without exhibits but including documents incorporated therein
by reference, as you may reasonably request.

     (c)         The Companies will prepare the Prospectus, the form and
substance of which shall be satisfactory to you, and file the Prospectus in
such form with the Commission within the applicable period specified in Rule
424(b) under the Act; during the period specified in Section 5(d) below, not
file any further amendment to the Registration Statement and not make any
amendment or supplement to the Prospectus of which you shall not previously
have been advised or to which you shall reasonably object after being so
advised; and, during such period, prepare and file with the Commission,
promptly upon your reasonable request, any amendment to the Registration
Statement or amendment or supplement to the Prospectus which may be necessary
or advisable in connection with the distribution of the Units by you, and to
use their respective best efforts to cause any such amendment to the
Registration Statement to become promptly effective.

                                       6


     (d)         The Companies will, prior to 10:00 A.M., New York City time,
on the first business day after the date of this Agreement and from time to
time thereafter for such period as in the opinion of counsel for the
Underwriters a prospectus is required by law to be delivered in connection with
sales by an Underwriter or a dealer, furnish in New York City to each
Underwriter and any dealer as many copies of the Prospectus (and of any
amendment or supplement to the Prospectus) and any documents incorporated
therein by reference as such Underwriter or dealer may reasonably request.

     (e)         If during the period specified in Section 5(d), any event
shall occur or condition shall exist as a result of which, in the opinion of
counsel for the Underwriters, it becomes necessary to amend or supplement the
Prospectus in order to make the statements therein, in the light of the
circumstances when the Prospectus is delivered to a purchaser, not misleading,
or if, in the opinion of counsel for the Underwriters, it is necessary to amend
or supplement the Prospectus to comply with applicable law, the Companies will
forthwith prepare and file with the Commission an appropriate amendment or
supplement to the Prospectus so that the statements in the Prospectus, as so
amended or supplemented, will not in the light of the circumstances when it is
so delivered, be misleading, or so that the Prospectus will comply with
applicable law, and furnish to each Underwriter and to any dealer as many
copies thereof as such Underwriter or dealer may reasonably request.

     (f)         The Companies will, prior to any public offering of the Units,
cooperate with you and counsel for the Underwriters in connection with the
registration or qualification of the Units for offer and sale by the several
Underwriters and by dealers under the state securities or Blue Sky laws of such
jurisdictions as you may request, continue such registration or qualification
in effect so long as required for distribution of the Units and file such
consents to service of process or other documents as may be necessary in order
to effect such registration or qualification; provided, however, that neither
of the Companies shall be required in connection therewith to qualify as a
foreign corporation in any jurisdiction in which they are not now so qualified
or to take any action that would subject it to general consent to service of
process or taxation other than as to matters and transactions relating to the
Prospectus, the Registration Statement, any preliminary prospectus or the

within the meaning of Section 15 of the Act or Section 20 of the Exchange Act,
to the same extent as the foregoing indemnity from the





<PAGE>   17
                                       17

Companies to such Underwriter but only with reference to information relating
to such Underwriter furnished in writing to the Companies by such Underwriter
through you expressly for use in the Registration Statement (or any amendment
thereto), the Prospectus (or any amendment or supplement thereto) or any
preliminary prospectus.

     (c)  In case any action shall be commenced involving any person in respect
of which indemnity may be sought pursuant to Section 7(a) or 7(b) (the
"indemnified party"), the indemnified party shall promptly notify the person
against whom such indemnity may be sought (the "indemnifying party") in writing
and the indemnifying party shall assume the defense of such action, including
the employment of counsel reasonably satisfactory to the indemnified party and
the payment of all fees and expenses of such counsel, as incurred (except that
in the case of any action in respect of which indemnity may be sought pursuant
to both Sections 7(a) and 7(b), the Underwriter shall not be required to assume
the defense of such action pursuant to this Section 7(c), but may employ
separate counsel and participate in the defense thereof, but the fees and
expenses of such counsel, except as provided below, shall be at the expense of
such Underwriter).   Any indemnified party shall have the right to employ
separate counsel in any such action and participate in the defense thereof, but
the fees and expenses of such counsel shall be at the expense of the
indemnified party unless (i) the employment of such counsel shall have been
specifically authorized in writing by the indemnifying party, (ii) the
indemnifying party shall have failed to assume the defense of such action or
employ counsel reasonably satisfactory to the indemnified party or (iii) the
named parties to any such action (including any impleaded parties) include both
the indemnified party and the indemnifying party, and the indemnified party
shall have been advised by such counsel that there may be one or more legal
defenses available to it which are different from or additional to those
available to the indemnifying party (in which case the indemnifying party shall
not have the right to assume the defense of such action on behalf of the
indemnified party).   In any such case, the indemnifying party shall not, in
connection with any one action or separate, but substantially similar or
related actions in the same jurisdiction arising out of the same general
allegations or circumstances, be liable for the fees and expenses of more than
one separate firm of attorneys (in addition to any local counsel) for all
indemnified parties and all such fees and expenses shall be reimbursed as they
are incurred.  Such firm shall be designated in writing by Donaldson, Lufkin &
Jenrette Securities Corporation, in the case of parties indemnified pursuant to
Section 7(a), and by the Company, in the case of parties indemnified pursuant
to Section 7(b). The indemnifying party shall indemnify and hold harmless the
indemnified party from and against any and all losses, claims, damages,
liabilities and judgments by reason of any settlement of any action (i)
effected with its written consent or (ii) effected without its written consent
if the settlement is entered into more than twenty business days after the
indemnifying party shall have received a request from the indemnified party for
reimbursement for the fees and expenses of counsel (in any case where such fees
and expenses are at the expense of the indemnifying party) and, prior to the
date of such settlement, the indemnifying party shall have failed to comply
with such reimbursement request.   No indemnifying party shall, without the
prior written consent





<PAGE>   18
                                       18

of the indemnified party, effect any settlement or compromise of, or consent to
the entry of  judgment with respect to, any pending or threatened action in
respect of which the indemnified party is or could have been a party and
indemnity or contribution may be or could have been sought hereunder by the
indemnified party, unless such settlement, compromise or judgment (i)  includes
an unconditional release of the indemnified party from all liability on claims
that are or could have been the subject matter of such action and (ii) does not
include a statement as to or an admission of fault, culpability or a failure to
act, by or on behalf of the indemnified party.

     (d)  To the extent the indemnification provided for in this Section 7 is
unavailable to an indemnified party or insufficient in respect of any losses,
claims, damages, liabilities or judgments referred to therein, then each
indemnifying party, in lieu of indemnifying such indemnified party, shall
contribute to the amount paid or payable by such indemnified party as a result
of such losses, claims, damages, liabilities and judgments (i) in such
proportion as is appropriate to reflect the relative benefits received by the
Companies on the one hand and the Underwriters on the other hand from the
offering of the Units or (ii) if the allocation provided by clause 7(d)(i)
above is not permitted by applicable law, in such proportion as is appropriate
to reflect not only the relative benefits referred to in clause 7(d)(i) above
but also the relative fault of the Companies on the one hand and the
Underwriters on the other hand in connection with the statements or omissions
which resulted in such losses, claims, damages, liabilities or judgments, as
well as any other relevant equitable considerations.  The relative benefits
received by the Companies on the one hand and the Underwriters on the other
hand shall be deemed to be in the same proportion as the total net proceeds
from the offering (before deducting expenses) received by the Companies, and
the total underwriting discounts and commissions received by the Underwriters,
bear to the total price to the public of the Units, in each case as set forth
in the table on the cover page of the Prospectus.  The relative fault of the
Companies on the one hand and the Underwriters on the other hand shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to
state a material fact relates to information supplied by the Companies or the
Underwriters and the parties' relative intent, knowledge, access to information
and opportunity to correct or prevent such statement or omission.

     The Companies and the Underwriters agree that it would not be just and
equitable if contribution pursuant to this Section 7(d) were determined by pro
rata allocation (even if the Underwriters were treated as one entity for such
purpose) or by any other method of allocation which does not take account of
the equitable considerations referred to in the immediately preceding
paragraph.  The amount paid or payable by an indemnified party as a result of
the losses, claims, damages, liabilities or judgments referred to in the
immediately preceding paragraph shall be deemed to include, subject to the
limitations set forth above, any legal or other expenses incurred by such
indemnified party in connection with investigating or defending any matter,
including any action, that could have given rise to such losses, claims,
damages, liabilities or judgments.  Notwithstanding the provisions of this
Section 7, no





<PAGE>   19
                                       19

Underwriter shall be required to contribute any amount in excess of the amount
by which the total price at which the Units underwritten by it and distributed
to the public were offered to the public exceeds the amount of any damages
which such Underwriter has otherwise been required to pay by reason of such
untrue or alleged untrue statement or omission or alleged omission.  No person
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the Act) shall be entitled to contribution from any person who was not guilty
of such fraudulent misrepresentation.  The Underwriters' obligations to
contribute pursuant to this Section 7(d) are several in proportion to the
respective number of Units purchased by each of the Underwriters hereunder and
not joint.

     (e)  The remedies provided for in this Section 7 are not exclusive and
shall not limit any rights or remedies which may otherwise be available to any
indemnified party at law or in equity.

     SECTION 8.  Conditions of Underwriters' Obligations.  The several
obligations of the Underwriters to purchase the Firm Units under this Agreement
are subject to the satisfaction of each of the following conditions:

     (a)  All the representations and warranties of the Companies contained in

force and effect as if made on and as of the Closing Date.

filed with the Commission in accordance with Rule 424(b) (or a post-effective
amendment providing such information shall have been filed and declared
effective in accordance with the requirements of Rule 430A) and, if the
Companies are required to file a Rule 462(b) Registration Statement after the
effectiveness of this Agreement, such Rule 462(b) Registration Statement shall
have become effective by 10:00 P.M., New York City time, on the date of this
Agreement; and no stop order suspending the effectiveness of the Registration
Statement shall have been issued and no proceedings for that purpose shall have
been commenced or shall be pending before or contemplated by the Commission.

     (c)  You shall have received on the Closing Date a certificate dated the
Closing Date, signed by Bruce D. Brydon and Robert A. Podruzny, in their
capacities as the President and Chief Executive Offer and Vice President and
Chief Financial Officer of Biovail, confirming the matters set forth in
Sections 6(s), 8(a) and 8(b) and that Biovail has complied with all of the
agreements and satisfied all of the conditions herein contained and required to
be complied with or satisfied by Biovail on or prior to the Closing Date.

     (d)  You shall have received on the Closing Date a certificate dated the

                                       20

forth in Sections 6(s), 8(a) and 8(b) and that Intelligent Polymers has
complied with all of the agreements and satisfied all of the conditions herein
contained and required to be complied with or satisfied by Intelligent Polymers
on or prior to the Closing Date.

     (e)  Since the respective dates as of which information is given in the
Prospectus other than as set forth in the Prospectus (exclusive of any
amendments or supplements thereto subsequent to the date of this Agreement),
(i) there shall not have occurred any change or any development involving a
prospective change in the condition, financial or otherwise, or the earnings,
business, management or operations of Biovail and its Subsidiaries, taken as a
whole, or Intelligent Polymers, (ii) there shall not have been any change or
any development involving a prospective change in the capital stock or in the
long-term debt of Biovail, any of its Subsidiaries or Intelligent Polymers and
(iii) neither Biovail, nor any of its Subsidiaries nor Intelligent Polymers
shall have incurred any liability or obligation, direct or contingent, the
effect of which, in any such case described in clause 8(d)(i), 8(d)(ii) or
8(d)(iii) in your judgment, is material and adverse and, in your judgment,
makes it impracticable to market the Units on the terms and in the manner
contemplated in the Prospectus.

         (i)  Opinion of General Counsel for Biovail and Intelligent Polymers.

amendments or supplements thereto (other than the documents incorporated

(including the documents incorporated therein by reference), but are without

Closing Date of such documents as you may reasonably request with respect to
the good standing of the Companies, the due authorization and issuance of such

     SECTION 9.  Effectiveness of Agreement and Termination.  This Agreement
shall become effective upon the execution and delivery of this Agreement by the
parties hereto.

     This Agreement may be terminated at any time on or prior to the Closing
Date by you by written notice to the Companies if any of the following has
occurred:  (i) any outbreak or escalation of hostilities or other national or
international calamity or crisis or change in economic conditions or in the
financial markets of the United States or elsewhere that, in your judgment, is
material and adverse and, in your judgment, makes it impracticable to market
the Shares on the terms and in the manner contemplated in the Prospectus, (ii)
the suspension or





<PAGE>   23
                                       23

material limitation of trading in securities or other instruments on the New
York Stock Exchange, the American Stock Exchange, the Chicago Board of Options
Exchange, the Chicago Mercantile Exchange, the Chicago Board of Trade or the
Nasdaq National Market or limitation on prices for securities or other
instruments on any such exchange or the Nasdaq National Market, (iii) the
suspension of trading of any securities of the Companies on any exchange or in
the over-the-counter market, (iv) the enactment, publication, decree or other
promulgation of any federal or state statute, regulation, rule or order of any
court or other governmental authority which in your opinion materially and
adversely affects, or will materially and adversely affect, the business,
prospects, financial condition or results of operations of Biovail and its
Subsidiaries, taken as a whole, or Intelligent Polymers, (v) the declaration of
a banking moratorium by either federal or New York State authorities or (vi)
the taking of any action by any federal, state or local government or agency in
respect of its monetary or fiscal affairs which in your opinion has a material
adverse effect on the financial markets in the United States.

     If on the Closing Date or on an Option Closing Date, as the case may be,
any one or more of the Underwriters shall fail or refuse to purchase the Firm
Units or Additional Units, as the case may be, which it or they have agreed to
purchase hereunder on such date and the aggregate number of Firm Units or
Additional Units, as the case may be, which such defaulting Underwriter or
Underwriters, as the case may be, agreed but failed or refused to purchase is
not more than one-tenth of the total number of Units to be purchased on such
date by all Underwriters, each non-defaulting Underwriter shall be obligated
severally, in the proportion which the number of Firm Units set forth opposite
its name in Schedule I bears to the total number of Firm Units which all the
non-defaulting Underwriters, as the case may be, have agreed to purchase, or in
such other proportion as you may specify, to purchase the Firm Units or
Additional Units, as the case may be, which such defaulting Underwriter or
Underwriters, as the case may be, agreed but failed or refused to purchase on
such date; provided that in no event shall the number of Firm Units or
Additional Units, as the case may be, which any Underwriter has agreed to
purchase pursuant to Section 2 hereof be increased pursuant to this Section 9
by an amount in excess of one-ninth of such number of Firm Units or Additional
Units, as the case may be, without the written consent of such Underwriter.  If
on the Closing Date any Underwriter or Underwriters shall fail or refuse to
purchase Firm Units and the aggregate number of Firm Units with respect to
which such default occurs is more than one-tenth of the aggregate number of
Firm Units to be purchased  by all Underwriters and arrangements satisfactory
to you and the Companies for purchase of such Firm Units are not made within 48
hours after such default, this Agreement will terminate without liability on
the part of any non-defaulting Underwriter and the Companies.   In any such
case which does not result in termination of this Agreement, either you or
either of the Companies shall have the right to postpone the Closing Date, but
in no event for longer than seven days, in order that the required changes, if
any, in the Registration Statement and the Prospectus or any other documents or
arrangements may be effected. If, on an Option Closing Date, any Underwriter or
Underwriters shall fail or refuse to purchase Additional  Units and





<PAGE>   24
                                       24

the aggregate number of Additional Units with respect to which such default
occurs is more than one-tenth of the aggregate number of Additional Units to be
purchased on such date, the non-defaulting Underwriters shall have the option
to (i) terminate their obligation hereunder to purchase such Additional Units
or (ii) purchase not less than the number of Additional Units that such
non-defaulting Underwriters would have been obligated to purchase on such date
in the absence of such default.  Any action taken under this paragraph shall
not relieve any defaulting Underwriter from liability in respect of any default
of any such Underwriter under this Agreement.

     SECTION 10.  Miscellaneous.  Notices given pursuant to any provision of
this Agreement shall be addressed as follows: (i) if to Biovail, to Biovail
Corporation International, 2488 Dunwin Drive, Mississauga, Ontario, Canada L5L
1J9, Attention: Robert A. Podruzny and (ii) if to Intelligent Polymers, Conyers
Dill & Pearman, Clarendon House, 2 Church Street, Hamilton HM 11, Bermuda,
Attention:  David J. Doyle and (iii) if to any Underwriter or to you, to you
c/o Donaldson, Lufkin & Jenrette Securities Corporation, 277 Park Avenue, New
York, New York 10122, Attention:  Syndicate Department, or in any case to such
other address as the person to be notified may have requested in writing.

     The respective indemnities, contribution agreements, representations,
warranties and other statements of the Companies and the several Underwriters
set forth in or made pursuant to this Agreement shall remain operative and in
full force and effect, and will survive delivery of and payment for the Units,
regardless of (i) any investigation, or statement as to the results thereof,
made by or on behalf of any Underwriter, the officers or directors of any
Underwriter, any person controlling any Underwriter, the Companies, the
officers or directors of the Companies or any person controlling the Companies,
(ii) acceptance of the Units and payment for them hereunder and (iii)
termination of this Agreement.

     If for any reason the Units are not delivered by or on behalf of the
Companies as provided herein (other than as a result of any termination of this
Agreement pursuant to Section 9), the Companies agree to reimburse the several
Underwriters for all out-of-pocket expenses (including the fees and
disbursements of counsel) incurred by them.  Notwithstanding any termination of
this Agreement, the Companies shall be liable for all expenses which  agreed to
pay pursuant to Section 5(i) hereof.  The Companies also agree to reimburse the
several Underwriters, their directors and officers and any persons controlling
any of the Underwriters for any and all fees and expenses (including, without
limitation, the fees disbursements of counsel) incurred by them in connection
with enforcing their rights hereunder (including, without limitation, pursuant
to Section 7 hereof).

     Except as otherwise provided, this Agreement has been and is made solely
for the benefit of and shall be binding upon the Companies, the Underwriters,
the Underwriters' directors and officers, any controlling persons referred to
herein, the Companies' directors and the Companies' officers who sign the
Registration Statement and their respective successors and





<PAGE>   25
                                       25

assigns, all as and to the extent provided in this Agreement, and no other
person shall acquire or have any right under or by virtue of this Agreement.
The term "successors and assigns" shall not include a purchaser of any of the
Units from any of the several Underwriters merely because of such purchase.

     This Agreement shall be governed and construed in accordance with the laws
of the State of New York.

     This Agreement may be signed in various counterparts which together shall
constitute one and the same instrument.

     Please confirm that the foregoing correctly sets forth the agreement
between the Company and the several Underwriters.

        FOR BIOVAIL AND INTELLIGENT POLYMERS TO BE DELIVERED PURSUANT TO
                                SECTION 8(f)(1)


         1.  The Underwriting Agreement has been duly authorized, executed and

         2.  Biovail has been duly incorporated, is validly existing as a
corporation under the laws of its jurisdiction of incorporation and has the
corporate power and authority to carry on its business as described in the
Prospectus and to own, lease and operate its properties, and is duly qualified
and is in good standing as a foreign corporation authorized to do business in
each jurisdiction in which the nature of its business or its ownership or

prospects, financial condition or results of operations of Biovail.

         3.  The authorized, issued and outstanding capital stock and the debt
of each of Biovail was at the date indicated as set forth in the Prospectus

         4.  The Biovail Common Shares issuable upon exercise of the Warrants

for in accordance with the terms of the Warrant Agreement, will be duly

Shares are not subject to the preemptive or similar rights of any shareholder
of Biovail; and all corporate action required to be taken for such

owned by Biovail, directly or through one or more of its Subsidiaries, free and
clear of any pledge, lien, security interest, charge, claim, equity or
encumbrance of any kind.

         6.  The execution, delivery and performance of the Underwriting
Agreement by Biovail and the compliance by Biovail with all the provisions
hereof and the consummation of the transactions contemplated hereby will not
(i) conflict with or constitute a breach of any of the terms or provisions of,
or a default under, the charter or by-laws of Biovail or any of its
Subsidiaries or any indenture, loan agreement, mortgage, lease or other
agreement or instrument that is material to Biovail and its Subsidiaries, taken
as a whole, to which Biovail or any of its Subsidiaries is a party or by which
Biovail or any of its Subsidiaries or their respective property is bound or
(ii) result in the suspension, termination or revocation of any Authorization
(as defined below) of Biovail or any of its Subsidiaries or any other
impairment of the rights of the holder of any such Authorization.

         7.  Neither Biovail nor any of its Subsidiaries is in violation of its
respective charter or by-laws or in default in the performance of any
obligation, agreement, covenant or condition contained in any indenture, loan
agreement, mortgage, lease or other agreement or instrument that is material to
Biovail and its Subsidiaries, taken as a whole to which Biovail or any of its
Subsidiaries is a party or by which Biovail or any of its Subsidiaries or their
respective property is bound.

         8.  There are no legal or governmental proceedings pending or
threatened to which Biovail or any of its Subsidiaries is or could be a party
or to which any of their respective property is or could be subject that are
required to be described in the Registration Statement or the Prospectus and
are not so described; nor are there any statutes, regulations, contracts or
other documents that are required to be described in the Registration Statement
or the Prospectus or to be filed as exhibits to the Registration Statement that
are not so described or filed as required.

         9.  Each of Biovail, its Subsidiaries and Intelligent Polymers, as the
case may be, has such permits, licenses, consents, exemptions, franchises,
authorizations and other approvals (each, an "AUTHORIZATION") of, and has made
all filings with and notices to, all governmental or regulatory authorities and
self-regulatory organizations and all courts and other tribunals, including,
without limitation, under any applicable laws regulating pharmaceutical
products and Environmental Laws, as are necessary to own, lease, license and
operate its respective properties and to conduct its business, except where the
failure to have any such Authorization or to make any such filing or notice
would not, singly or in the aggregate, have a material adverse effect on the
business, prospects, financial condition or results of operations of Biovail
and its Subsidiaries, taken as a whole, or Intelligent Polymers, as the case
may be.  Each such Authorization is valid and in full force and effect and each
of Biovail, its Subsidiaries, and Intelligent Polymers, as the case may be, is
in compliance with all the terms and conditions thereof and with the rules and
regulations of the authorities and governing bodies having jurisdiction with
respect thereto; and no event has occurred (including, without limitation, the





                                      A-2
<PAGE>   30
receipt of any notice from any authority or governing body) which allows or,
after notice or lapse of time or both, would allow, revocation, suspension or
termination of any such Authorization or results or, after notice or lapse of
time or both, would result in any other impairment of the rights of the holder
of any such Authorization; and such Authorizations contain no restrictions that
are burdensome to Biovail, any of its Subsidiaries, or Intelligent Polymers, as
the case may be; except where such failure to be valid and in full force and
effect or to be in compliance, the occurrence of any such event or the presence
of any such restriction would not, singly or in the aggregate, have a material
adverse effect on the business, prospects, financial condition or results of
operations of Biovail and its Subsidiaries, taken as a whole, or Intelligent
Polymers, as the case may be.

         10.  Each of Biovail and its Subsidiaries have good and marketable
title in fee simple to all real property and good and marketable title to all
personal property owned by them which is material to the business of Biovail
and its Subsidiaries in each case free and clear of all liens, encumbrances and
defects except such as are described in the Prospectus or such as do not
materially affect the value of such property and do not interfere with the use
made and proposed to be made of such property by Biovail and its Subsidiaries;
and any real property and buildings held under lease by Biovail and its
Subsidiaries are held by them under valid, subsisting and enforceable leases
with such exceptions as are not material and do not interfere with the use made
and proposed to be made of such property and buildings by Biovail and its
Subsidiaries in each case except as described in the Prospectus.

         l1.  Neither Biovail, nor any of its Subsidiaries has violated any
foreign, federal, state or local law or regulation relating to the protection
of human health and safety, the environment or hazardous or toxic substances or
wastes, pollutants or contaminants ("ENVIRONMENTAL LAWS") or any provisions of
the Employee Retirement Income Security Act of 1974, as amended, or the rules
and regulations promulgated thereunder, except for such violations which,
singly or in the aggregate, would not have a material adverse effect on the
business, prospects, financial condition or results of operation of Biovail and
its Subsidiaries, taken as a whole.

         12.  There are no costs or liabilities associated with Environmental
Laws (including, without limitation, any capital or operating expenditures
required for clean-up, closure of properties or compliance with Environmental
Laws or any Authorization, any related constraints on operating activities and
any potential liabilities to third parties) which would, singly or in the
aggregate, have a material adverse effect on the business, prospects, financial
condition or results of operations of Biovail and its Subsidiaries, taken as a
whole.

         13.  Biovail and each of its Subsidiaries have filed all tax returns
which are required to be filed by them pursuant to domestic or foreign laws and
have paid all taxes due pursuant to such returns or pursuant to any assessment
received by them (except where the requirement for payment of such taxes is
being contested in good faith in appropriate proceedings).  The charges,
accruals and reserves on the books of Biovail and its Subsidiaries in respect
of taxes or other governmental charges are, to the best knowledge of Biovail
and its Subsidiaries, after reasonable investigation, adequate.





                                      A-3

         14.  There are no contracts, agreements or understandings between
Biovail and any person granting such person the right to require Biovail to
file a registration statement under the Act with respect to any securities of
Biovail or to require Biovail to include such securities with the Units
registered pursuant to the Registration Statement.

         15.  The Registration Statement and the Prospectus and any supplement
or amendment thereto (except for the financial statements and other financial
data included therein as to which no opinion need be expressed) comply as to
form with the Act, (A)  each document, if any, filed pursuant to the Exchange
Act and incorporated by reference in the Prospectus (except for financial
statements and other financial data included therein as to which no opinion
need be expressed) complied when so filed as to form with the Exchange Act, (B)
such counsel has no reason to believe that at the time the Registration
Statement became effective or on the date of this Agreement, the Registration
Statement and the prospectus included therein (except for the financial
statements and other financial data as to which such counsel need not express
any belief) contained any untrue statement of a material fact or omitted to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading and (C) such counsel has no reason to believe
that the Prospectus, as amended or supplemented, if applicable (except for the
financial statements and other financial data, as aforesaid) contains any
untrue statement of a material fact or omits to state a material fact necessary
in order to make the statements therein, in the light of the circumstances
under which they were made, not misleading.

         In giving such opinions with respect to the matters covered by Section
15, counsel may state that their opinion and belief are based upon their
participation in the preparation of the Registration Statement and Prospectus
and any amendments or supplements thereto and documents incorporated therein by
reference and review and discussion of the contents thereof, but is without
independent check or verification except as specified.

                     of less than US$3 million (the "Financial Notice") although
                     Biovail may at its election extend such period by providing
                     additional funding for the continued development of all of
                     the Products (but in no event beyond September 30, 2002);
                     provided, however, if Biovail prior to such 90th day shall
                     provide written confirmation to the Company that Biovail
                     shall use commercially reasonable efforts, at no expense to
                     the Company beyond the Available Funds, to continue to
                     develop the Products for so long as Biovail continues to

                     extended the termination date of the Purchase Option, the  
                     Company and Biovail will commence negotiations (for a      
                     maximum period of 60 days) as to the terms on which Biovail
                     might provide additional funding for any or all of the     
                     Products, taking into account relevant issues such as the  
                     amount and timing of such funding, possible alterations in 
                     the Biovail Option price if the Biovail Option has not yet 
                     been exercised or the possibility of granting Biovail a    
                     renewed Biovail Option if the Biovail Option has been      
                     exercised, and alterations in the royalty payment terms in 
                     the event that Biovail does not ultimately choose to       
                     exercise the Biovail Option. If the Company and Biovail    
                     successfully negotiate new funding terms, the Purchase

                     shall be cash in Dollars save that, if Biovail Securities 
                     or securities of a Majority Special Shareholder, if other  
                     than Biovail, are listed on a national securities exchange

                     trading privileges or listed on NASDAQ, it may be wholly or
                     partially satisfied in Biovail Securities or the securities
                     of such other Majority Shareholder at the election of the

               (iii) to the extent that such consideration is in the form of 
                     Biovail Securities or the securities of such other Majority

         (5)   Within 14 days of the giving of the Exercise Notice the Directors

Bye-Law, the Company shall execute an instrument of transfer over the relevant
Common Shares and register the same and such transfer to or upon the order of
the Majority Special Shareholders and such registration shall be valid and
binding upon the Common Shareholder as if he had validly executed such transfer
(notwithstanding the death or insanity of the Common Shareholder) and the
Company shall hold the attributable part of the consideration upon trust for the
Common Shareholder subject to the Common Shareholder providing the Directors
with satisfactory evidence of title to such Common Shares but so that if at the
expiry of two years following the said last date for delivery the Common
Shareholder shall not have furnished such evidence as aforesaid the Company
shall thereupon hold such consideration upon trust for the Majority Special

                     anything to the contrary in these Bye-Laws) be effective 
                     without the prior sanction in writing of the Majority

of payment. The joint holders of a share shall be jointly and severally liable
to pay all calls in respect thereof.

     (2) The Board may, on the issue of shares, differentiate between the
holders as to the amount of calls to be paid and the times of payment of such

for non-payment of call..

     (2) If the requirements of such notice are not complied with, any such
share may at any time thereafter before the payment of such call and the
interest due in respect thereof be forfeited by a resolution of the Board to
that effect, and such share shall thereupon become the property of the Company

60.  Inspection of Register of Members

     The Register of Members shall be open to inspection at the registered
office of the Company on every business day, subject to such reasonable
restrictions as the Board may impose, so that not less than two hours in each
business day be allowed for inspection. The Register of Members may, after
notice has been given by advertisement in an appointed newspaper to that
effect, be closed for any time or times not exceeding in the whole thirty days
in each year.

61.  Determination of record dates

     Notwithstanding any other provision of these bye-laws, the Board may fix
any date as the record date for:

                               TRANSFER OF SHARES

62.  Instrument of transfer

     (1) An instrument of transfer shall be in the usual common form or in
such other form as the Board may accept. Such instrument of transfer shall be
signed by or on behalf of the transferor and transferee provided that, in the
case of a fully paid share, the Board and/or the Company's duly appointed
Registrar and Transfer Agent may accept the instrument signed by or on behalf
of the transferor alone. The transferor shall be deemed to remain the holder of
such share until the same has been transferred to the transferee in the
Register of Members.

     (2) The Board and/or the Company's duly appointed Registrar and
Transfer Agent may refuse to recognise any instrument of transfer unless it is
accompanied by the certificate in respect of the shares to which it relates and
by such other evidence as the Board may reasonably require to show the right of
the transferor to make the transfer.

63.  Transfers by joint holders

     The joint holders of any share or shares may transfer such share or
shares to one or more of such joint holders, and the surviving holder or
holders of any share or shares previously held by them jointly with a deceased
Member may transfer any such share to the executors or administrators of such
deceased Member.

                             TRANSMISSION OF SHARES

64.  Representative of deceased Member

     In the case of the death of a Member, the survivor or survivors where
the deceased Member was a joint holder, and the legal personal representatives
of the deceased Member where the deceased Member was a sole holder, shall be
the only persons recognised by the Company as having any title to the deceased
Member's interest in the shares. Nothing herein contained shall release the
estate of a deceased joint holder from any liability in respect of any share
which had been jointly held by such deceased Member with other persons. Subject
to the provisions of Section 52 of the Act, for the purpose of this Bye-law,
legal personal representative means the executor or administrator of a deceased
Member or such other person as the Board may in its absolute discretion decide
as being properly authorised to deal with the shares of a deceased Member.

65.  Registration on death or bankruptcy

     Any person becoming entitled to a share in consequence of the death or
bankruptcy of any Member may be registered as a Member upon such evidence as
the Board may deem sufficient or may elect to nominate some person to be
registered as a transferee of such share, and in such case the person becoming
entitled shall execute in favour of such nominee an instrument of transfer in
the usual common form. On the presentation thereof to the Board, accompanied by
such evidence as the Board may require to prove the title of the transferor,
the transferee shall be registered as a Member but the Board shall, in either
case, have the same right to decline or suspend registration as it would have
had in the case of a transfer of the share by that Member before such Member's
death or bankruptcy, as the case may be.

                       DIVIDENDS AND OTHER DISTRIBUTIONS

66.  Declaration of dividends by the Board

     The Board may, subject to these bye-laws and in accordance with Section
54 of the Act, declare a dividend to be paid to the Members, in proportion to
the number of shares held by them, and such dividend may be paid in cash or
wholly or partly in specie in which case the Board may fix the value for 
distribution in specie of any assets.

67.  Other distributions

     The Board may declare and make such other distributions (in cash or in
specie) to the Members as may be lawfully made out of the assets of the
Company.

68.  Reserve fund

     The Board may from time to time before declaring a dividend set aside,
out of the surplus or profits of the Company, such sum as it thinks proper as a
reserve fund to be used to meet contingencies or for equalising dividends or
for any other special purpose.

69.  Deduction of Amounts due to the Company

     The Board may deduct from the dividends or distributions payable to
any Member all monies due from such Member to the Company on account of calls
or otherwise.

     (1)  The Board may resolve to capitalise any part of the amount for the
time being standing to the credit of any of the Company's share premium or
other reserve accounts or to the credit of the profit and loss account or
otherwise available for distribution by applying such sum in paying up unissued
shares to be allotted as fully paid bonus shares pro rata to the Members.

     (2)  The Company may capitalise any sum standing to the credit of a
reserve account or sums otherwise available for dividend or distribution by
applying such amounts in paying up in full partly paid shares of those Members
who would have been entitled to such sums if they were distributed by way of
dividend or distribution.

                       ACCOUNTS AND FINANCIAL STATEMENTS

71.  Records of account

     The Board shall cause to be kept proper records of account with
respect to all transactions of the Company and in particular with respect to:-

          matters in respect of which the receipt and expenditure relates;

     (c)  the assets and liabilities of the Company.

Such records of account shall be kept at the registered office of the Company
or, subject to Section 83 (2) of the Act, at such other place as the Board
thinks fit and shall be available for inspection by the Directors during normal
business hours.

72.  Financial year end

     The financial year end of the Company may be determined by resolution
of the Board and failing such resolution shall be 31st December in each year.

73.  Financial statements

81.  Service and delivery of notice

     Any notice shall be deemed to have been served at the time when the
same would be delivered in the ordinary course of transmission and, in proving
such service, it shall be sufficient to prove that the notice was properly
addressed and prepaid, if posted, and the time when it was posted, delivered to
the courier or to the cable company or transmitted by telex, facsimile or other
method as the case may be.

                              SEAL OF THE COMPANY

<PAGE>   38
                                      -34-

as he or she deems fair upon any property to be divided as aforesaid and may
determine how such division shall be carried out as between the Members or

                               WARRANT AGREEMENT


                  WARRANT AGREEMENT (the "AGREEMENT'), dated as of October __,
1997, between Biovail Corporation International (the "COMPANY"), a corporation
organized and existing under the laws of Ontario, Canada and Chase Mellon
Shareholder Services, L.L.C., a New Jersey limited liability company (the
"WARRANT AGENT"), in favor of each of the persons (each a "HOLDER") who
acquires from time to time warrants to purchase the Company's common shares, no
par value (the "COMMON SHARES"), issued in the offering of units (collectively,
the "UNITS"), each Unit consisting of one warrant to purchase one Common Share
(each, a "WARRANT" and collectively, the "WARRANTS") and one common share, par
value $.01 per share, of Intelligent Polymers Limited, a corporation organized
and existing under the laws of Bermuda (the "INTELLIGENT POLYMERS COMMON
SHARES"), made pursuant to a Registration Statement on Form F-1/F-3 (Nos.
333-35833 and 333-35839) (the "REGISTRATION STATEMENT") filed by the Company
and Intelligent Polymers Limited with the Securities and Exchange Commission
(the "SEC").


THE PARTIES AGREE IN FAVOR OF EACH HOLDER AS FOLLOWS:

                  Until September 30, 1999 or such earlier date as the Purchase
Option (as defined in the Registration Statement) is exercised or expires
unexercised (the "Separation Date"), each Warrant shall be evidenced by a unit
certificate (the "UNIT CERTIFICATE") in the form filed as Exhibit 4.4 to the
Registration Statement. On or immediately after the Separation Date, the
Warrant Agent will issue to each Holder a certificate, representing a warrant
certificate, such warrant certificate to be substantially in the form attached
hereto as Exhibit A (each, a "WARRANT CERTIFICATE"; it being understood that
prior to the Separation Date, the term "Warrant Certificate" shall mean the
Unit Certificate). Each Holder, upon execution of a Warrant Certificate by the
Company and the countersignature by the Warrant Agent, shall be entitled to
purchase from the Company, subject to the provisions of this Agreement, the
number of Common Shares (collectively, the "WARRANT SHARES") as shall equal the
number of Common Shares indicated in the Warrant Certificate issued to such
Holder. The Warrant shall be exercisable at any time from October 1, 1999 (the
"EXERCISE COMMENCEMENT DATE") through September 30, 2002 (the "EXERCISE
PERIOD") at the exercise price per Common Share of $_____ (the "EXERCISE
PRICE").

                  The number of Warrant Shares to be received upon exercise of
the Warrants and payment of the Exercise Price shall be adjusted from time to
time as set forth in Section 8 of this Agreement. The Warrants will
additionally be subject to the following terms and conditions:

                  1.  Execution for Warrant Certificates.  The Warrant 
Certificates shall be executed on behalf of the Company by its President and
Chief Executive Officer or any Vice President and by its Secretary, either
manually or by facsimile signature printed thereon. The


<PAGE>   2
                                       2


Warrant Certificates shall be manually countersigned and dated the date of
countersignature by the Warrant Agent and shall not be valid for any purpose
unless so countersigned and dated. In case any authorized officer of the
Company who shall have signed any of the Warrant Certificates shall cease to be
such officer of the Company either before or after delivery thereof by the
Company to the Warrant Agent, the signature of such officer on such Warrant
Certificates, nevertheless, shall be valid and such Warrant Certificates may be
countersigned by the Warrant Agent, and issued and delivered to those persons
entitled to receive the Warrants represented thereby with the same force and
effect as though the person who signed such Warrant Certificates had not ceased
to be such officer of the Company.

                  2. Appointment of Warrant Agent.  The Company hereby 
appoints the Warrant Agent to act as agent for the Company in accordance with
the instructions set forth herein, and the Warrant Agent hereby accepts such
appointment, upon the terms and conditions hereinafter set forth.

                  3. Appointment of Transfer Agent and Registrar. The Company
hereby appoints the Warrant Agent to be the Transfer Agent and Registrar of the
Unit Certificates and the Warrant Agent agrees to act as Transfer Agent and
Registrar of the Unit Certificates until the Separation Date. After the
Separation Date, the Warrant Agent will act as Warrant Agent for the Warrants
pursuant to this Agreement.

                  4. Exercise of Warrants. Subject to the terms and conditions
hereof, the Warrants may be exercised by the Holder thereof, in whole or in
increments of 10 Common Shares, on any business day beginning on the Exercise
Commencement Date, or if such date is not a business day, then on the next
succeeding business day, by presentation and surrender of the Warrant
Certificates at the office of the Warrant Agent with the ELECTION TO PURCHASE
(set forth on the reverse side of the Warrant Certificate) properly completed
and duly executed and accompanied by payment, by certified or official bank
check, payable to the order of the Company, of an amount in United States
dollars equal to the then current Exercise Price for the number of Warrant
Shares specified in such Election to Purchase. The applicable fees of the
Warrant Agent, in connection with such exercise shall be paid by the Company.
If the Warrants are exercised for less than the total number of Warrant Shares
evidenced by the Warrant Certificate, promptly after presentation of the
Warrant Certificate upon such exercise, the Warrant Agent shall execute and
deliver a new Warrant Certificate, dated the date hereof, evidencing the rights
of the Holder to purchase the balance of the Warrant Shares purchasable
hereunder upon the same terms and conditions herein set forth. Upon and as of
receipt by the Warrant Agent of the Warrant Certificate with a properly
completed and duly executed Election to Purchase accompanied by payment of the
Exercise Price as herein provided and upon receipt by the Warrant Agent from
the Company of the appropriate amount of Common Shares represented by such
Warrant Shares purchasable upon the exercise of the Warrant, the Holder shall
be deemed to be the holder of record of the Common Shares issuable upon such
exercise, notwithstanding that the share transfer books of the Company may then 
be closed or that 


<PAGE>   3
                                       3



certificates representing such Common Shares may not then actually be delivered
to the Holder. Each Warrant not exercised prior to 5:00 p.m., New York City
time, on September 30, 2002 (the "EXPIRATION DATE"), shall become void, and all
rights hereunder and under the applicable Warrant Certificate(s) and all rights
in respect thereof under this Agreement shall cease as of such time. Subsequent
to the proper exercise of the Warrant(s) by the Holder, the Warrant Agent shall
promptly transfer to the Holder appropriate evidence of ownership of the
Warrant Shares or other securities or property to which the Holder is entitled,
registered or otherwise placed in, or payable to the order of, such name or
names as may be directed in writing by the Holder, and shall promptly deliver
such evidence of ownership of any other securities or property to the person or
persons entitled to receive such items. The term "business day" as used in this
Agreement shall mean any day other than a Saturday, Sunday or a day on which
federal or state chartered banking institutions in New York City, New York are
authorized or required by law to close.

                  5. Payment of Taxes. The Company will pay all documentary
stamp taxes attributable to the original issuance of the Warrants and of the
Common Shares issuable upon the exercise of the Warrants; provided, however,
that the Company shall not be required to (a) pay any tax which may be payable
in respect of any transfer involved in the transfer and delivery of the Warrant
Certificates or the issuance or delivery of certificates for Warrant Shares in
a name other than that of the registered holder of the Warrant Certificate
surrendered upon the exercise of a Warrant or (b) issue or deliver any
certificate for Warrant Shares upon the exercise of any Warrants until any such
tax required to be paid under clause (a) shall have been paid, all such tax
being payable by the holder of such Warrant at the time of surrender.

                  6. Reservation of Warrant Shares. The Company shall, at all
times from the Exercise Commencement Date until the Expiration Date, reserve
for issuance and delivery upon exercise of the Warrants the number of Common
Shares as shall be required for issuance and delivery upon exercise of the
Warrants. All such shares shall be duly authorized and, when issued upon such
exercise, shall be validly issued, fully paid and nonassessable,
freely-tradeable and free and clear of all liens, security interests, charges
and other encumbrances or restrictions on sale and free and clear of all
preemptive rights. The Warrant Agent is hereby irrevocably authorized to
requisition from time to time Common Share share certificates issuable upon the
exercise of outstanding Warrants. The Company will supply its transfer agent
with duly executed share certificates for such purpose. All Warrants
surrendered upon exercise shall be canceled by the Warrant Agent and shall
thereafter be delivered to the Company or otherwise disposed of in a manner
satisfactory to the Company. Unless all Warrants shall have been exercised
prior to 5:00 p.m., New York time, on the Expiration Date, the Warrant Agent
shall certify to the Company, as of the close of business on the Expiration
Date, the total aggregate amount of Warrants then outstanding, and thereafter
no shares of Common Shares shall be subject to reservation in respect of such
Warrants. The Company shall keep a copy of this Agreement on file with its
transfer agent and with every transfer agent for any Common Shares.

                                       4



                  7.  Market Price of Shares.  For purposes of this 
Agreement, the market price (the "MARKET PRICE") of the Common Shares for the
relevant day or days shall be determined by the Company as follows:

                  (a) if the Common Shares are listed on any United States
         national securities exchanges or admitted to unlisted trading
         privileges on any such exchanges, the Market Price shall be the
         average of the closing prices of the Common Shares on the principal
         exchange on which such shares are listed or admitted to unlisted
         trading privileges over the five trading days immediately preceding
         the applicable date; or

                  (b) if the Common Shares are quoted on the National Market
         System of the National Association of Securities Dealers Inc.
         Automatic Quotation System ("NASDAQ"), the Market Price shall be the
         average of the last sale prices of the Common Shares as reported on
         the Nasdaq National Market System, or, if the Common Shares are not
         included in the Nasdaq National Market System, the average of the bid
         prices for the Common Shares as reported on the Nasdaq quotation
         system, in either case over the five trading days immediately
         preceding the applicable date; or

                  (c) if the Common Shares are not so quoted on Nasdaq or
         listed on any United States national securities exchange or admitted
         to unlisted trading privileges, the Market Price of the Common Shares
         shall be an amount representing the fair market value of the Common
         Shares as determined in good faith by the Board of Directors of the
         Company.

                  8.  Adjustments.

                  (a) Stock Dividends; etc. If after the date hereof the number
of outstanding Common Shares is increased by a stock dividend payable in Common
Shares of the Company or by an allotment of Common Shares or other securities
of the Company made to Holders of Common Shares by way of a capitalization of
reserves or subdivision of Common Shares or by a reclassification of Common
Shares then, from and after the day following the record date for such share
dividend or allotment or reclassification, the number of Warrant Shares
issuable upon exercise of the Warrants shall be increased in proportion to such
increase in outstanding Common Shares of the Company and the then applicable
Exercise Price shall be correspondingly decreased.

                  (b) Aggregation of Shares. If, after the date hereof, the
number of outstanding Common Shares of the Company is decreased by a
consolidation or reclassification of Common Shares of the Company, then, from
and after the record date for such consolidation or reclassification, the
number of Warrant Shares issuable upon exercise of the Warrants shall be
decreased in proportion to such decrease in Common Shares of the Company and
the then applicable Exercise Price shall be correspondingly increased.


<PAGE>   5
                                       5




                  (c) Special Dividends. If (other than in a dissolution or
liquidation) securities of the Company (other than the Common Shares) or assets
(other than cash dividends payable out of retained earnings) are issued by way
of a dividend on outstanding Common Shares of the Company as of a record date,
then the Exercise Price shall be adjusted so that it shall equal the price
determined by multiplying the Exercise Price in effect immediately prior to the
close of business on such record date by a fraction, the numerator of which
shall be the Market Price on such record date less then fair market value (as
determined by the Board of Directors of the Company, whose determination shall
be conclusive) of the securities or assets distributed applicable to one Common
Share, and the denominator of which shall be such Market Price. Such
adjustments shall become effective immediately prior to the opening of business
on the day following such record date.

                  (d) Reorganization, etc. If there shall be effected any
amalgamation or merger of the Company with another corporation, other entity or
any sale of all or substantially all of the Company's assets to another entity
in which holders of Common Shares will receive in exchange for their Common
Shares other securities or assets, then, as a condition to the closing of such
amalgamation, merger, or sale, lawful and fair provision shall be made whereby
the Holders thereafter shall have the right to purchase and receive, upon the
basis and upon the terms and conditions specified in the Warrants and in lieu
of the Warrant Shares issuable upon exercise of the Warrants, such shares of
stock, securities, or assets as may be issued or payable with respect to or in
exchange for the number of Warrant Shares issuable upon the exercise of the
Warrants prior to the closing of such amalgamation, merger or sale. In any such
case appropriate provision shall be made with respect to the rights and
interests of the Holders to the end that the provisions hereof (including,
without limitation, provisions for adjustments of the Exercise Price and of the
number of Warrant Shares purchasable upon the exercise of the Warrants) shall
thereafter be applicable, as nearly as may be practicable, in relation to any
share of stock, securities, or assets thereafter deliverable upon the exercise
hereof. The Company shall not effect any such amalgamation, merger, or sale
unless prior to the consummation thereof the successor entity (if other than
the Company) resulting from such amalgamation or merger, or the entity
purchasing such assets, shall assume by written instrument executed and
delivered to the Warrant Agent the obligation to deliver to the Holders such
shares of stock, securities, or assets as, in accordance with the foregoing
provisions, such Holders may be entitled to purchase.

                  (e) Limitations. Anything in this Section 8 to the contrary
notwithstanding, adjustments in the number of Warrant Shares issuable on
exercise of Warrants shall be made only to the nearest one-tenth on a Common
Share.

                  (f) Readjustments; etc. If an adjustment is made under
paragraph (a), (b), (c) or (d) above, and the event to which the adjustment
relates does not occur, then any adjustments in the Exercise Price or Warrant
Shares that were made in accordance with such paragraphs shall 

<PAGE>   6
                                       6



be adjusted back to the Exercise Price and the number of Warrant Shares that
were in effect immediately prior to the record date for such event.

                  (g) No Adjustments to Exercise Price. No adjustment in the
Exercise Price in accordance with the provisions of paragraph (a), (b), (c) or
(d) above need be made if such adjustment would amount to a change in such
Exercise Price of less than $.05; provided, however, that the amount by which
any adjustment is not made by reason of the provisions of this Section 8 shall
be carried forward and taken into account at the time of any subsequent
adjustment in the Exercise Price.

                  (h) Form of Warrant Certificate. The form of Warrant
Certificate need not be changed as a result of any change pursuant to this
Section 8, and any Warrant Certificate issued after such change may state the
same Exercise Price and the same number of Warrant Shares as is stated in the
Warrant Certificate initially issued pursuant to this Agreement.
Notwithstanding the foregoing, the Company shall have the right at any time
from time to time in its sole discretion (which shall be conclusive) to make
any change in the Warrant Certificate that the Company may deem appropriate and
that does not affect the substance thereof; and any Warrant Certificate
thereafter issued or countersigned, whether in exchange or substitution for an
outstanding Warrant or otherwise, may be in the form as so changed.

                  (i) Notice of Adjustment in Warrant. Upon any adjustment of
the Exercise Price or the number of Warrant Shares issuable on exercise of the
Warrants, then in each such case, the Company shall give written notice thereof
to the Warrant Agent, which notice shall state the Exercise Price resulting
from such adjustment and the increase or decrease, if any, in the number of
Warrant Shares purchasable at such price upon the exercise of a Warrant,
setting forth in reasonable detail the method of calculation and the facts upon
which such calculation is based. The Company shall also mail such notice to the
Holders at their addresses registered with the Company or the Warrant Agent.
Failure to give such notice, or any defect therein, shall not affect the
legality or validity of the subject adjustments.

                  (j) Certificate of Independent Public Accounts. The Company
may retain a firm of independent public accountants of recognized standing
(which may be any such firm regularly employed by the Company) to make any
computation required under this Section 8, and a certificate signed by such
firm shall be conclusive evidence of the correctness of the computation made
under this Section 8.

                  9.  Voluntary Adjustment by the Company.  The Company may at 
its option, at any time during the term of the Warrants, reduce the then
current Exercise Price to any amount and for any period of time deemed
appropriate by the Board of Directors of the Company, including such reductions
in the Exercise Price as the Company considers to be advisable in order that
any event treated for income tax purposes as a dividend of share or share
rights shall not be taxable to the recipients.

                  10. No Rights as Stockholders; Notices.

                  (a) No Rights as Stockholders. Nothing contained in this
Agreement or in any of the Warrant Certificates shall be construed as
conferring upon the Holders, as such, the right to vote or to consent or to
receive notice as shareholders in respect of the meetings of shareholders or
the election of directors of the Company or any other matter, or any rights
whatsoever, at law or in equity, as shareholders of the Company.

                  (b) Notice Requirements.  In the event that:

                  (i) the Company shall take action to make any distribution
         (other than cash dividends payable out of accumulated earnings, as
         indicated on the most recent quarterly balance sheet of the Company,
         and dividends or distributions payable in Common Shares) to the
         holders of Common Shares;

                 (ii) the Company shall take action to offer for subscription
         pro rata to the holders of Common Shares any additional shares of any
         class or other rights or securities convertible into Common Shares;

                (iii) the Company shall take action to accomplish any capital
         reorganization, or reclassification of the share capital of the
         Company (other than a share dividend, allotment, subdivision or
         consolidation covered by Sections 8(a) or 8(b)) or amalgamation or
         merger to which the Company is a party and for which approval of any
         shareholders of the Company is required, or sale of all or
         substantially all of its assets to another corporation; or

                 (iv) the Company shall take action looking to a voluntary or 
         involuntary dissolution, liquidation, or winding up of the Company;

then, in any one or more of such cases, the Company shall (A) at least 10 days
prior to the record date or expected record date for any such distribution or
subscription rights or at least 10 days prior to the record date or expected
record date for determining rights to vote in respect of any such amalgamation,
merger, sale, dissolution, liquidation or winding up, cause written notice
thereof to be sent by first-class mail or by reputable overnight delivery
service or courier, postage prepaid, to the Warrant Agent and each Holder at
its address appearing in the records of the Warrant Agent or the Company, and
(B) in the case of any such reorganization, reclassification, consolidation,
merger, sale, dissolution, liquidation, or winding up, cause at least 10 days'
prior written notice of the date or expected date when the same shall take
place to be given to the Warrant Agent and each Holder in the same manner. Such
notice in accordance with the foregoing clause (A) shall also specify, in the
case of any such distribution or subscription rights, the date or expected date
on which the holders of Common Shares shall be entitled thereto, and such in
accordance with the foregoing clause (B) shall also specify the


<PAGE>   8
                                       8



date or expected date on which the holders of Common Shares shall be entitled
to exchange their Common Shares for securities or other property deliverable
upon such reorganization, reclassification, consolidation, merger, sale,
dissolution, liquidation or winding up, as the case may be. Failure to mail
such notice, or any defect therein, shall not affect the legality or validity
or any of the matters set forth in the foregoing clauses (i) through (iv). The
notice herein required shall not confer upon any Holder the right to exercise
the Warrants before the Exercise Commencement Date.

                  11. Transfer, Exchange, Assignment or Loss of Warrant 
Certificate.

                  (a) Transferability.  The Warrants may be transferred, in 
whole or in part, subject to the following restrictions:

                  (i) The Warrants may not be transferred separately from the
         Intelligent Polymers Common Shares with which the Warrants were issued
         as units until the Separation Date and the Warrants shall be
         transferred separately from the Intelligent Polymers Common Shares
         after the Separation Date. Requests for transfer of the Warrants
         before the Separation Date shall be forwarded to the Warrant Agent.

                 (ii) The Warrants, the Warrant Shares and any other
         securities received pursuant to this Agreement or the Warrants shall
         be subject to any restrictions on transferability provided by federal
         and state securities laws.

                  (b) Transfer Conditions. Any transfer permitted hereunder
shall be made by surrender of the Warrant Certificate to the Warrant Agent at
its offices with the FORM OF TRANSFER (on the reverse side of the Warrant
Certificate) properly completed and duly executed and accompanied by funds
sufficient to pay any transfer taxes applicable. Upon satisfaction of all
transfer conditions, the Warrant Agent shall, without charge, execute and
deliver a new Warrant Certificate in the name of the transferee named in such
Form of Transfer and the transferred Warrant Certificate shall be promptly
cancelled.

                  (c) Loss of Certificates. Upon receipt by the Warrant Agent
of evidence satisfactory to it of loss, theft, destruction or mutilation of the
Warrant Certificate and, in the case of loss, theft or destruction, upon
receipt of an indemnity bond satisfactory to the Warrant Agent (obtained by the
Holder at the Holder's expense) or, in the case of mutilation, upon surrender
of the Warrant Certificate, the Warrant Agent shall execute and deliver a new
Warrant Certificate of like tenor and date and any such lost, stolen, destroyed
or mutilated Warrant Certificate thereupon shall become void.

                  (d) Indemnity. Each holder of the Warrants and the Warrant
Shares shall indemnify and hold harmless the Company, its directors and
officers, and each other person, if any, who controls the Company, against any
losses, claims, damages or liabilities, joint or


<PAGE>   9
                                       9



several, to which the Company or any such director, officer or any such person
may become subject under the Securities Act of 1933, as amended (the "ACT"), or
any statute or common law, insofar as such losses, claims, damages or
liabilities, or actions in respect thereof, arise out of or are based upon the
disposition by such holder of the Warrant or the Warrant Shares in violation of
the Warrant Certificate or this Agreement.

                  12. Transfer Agent and Registrar of Unit Certificates. The
Warrant Agent shall keep, at its office at its Corporate Trust Office, 450 West
33rd Street, New York, New York 10001, a Unit Register in which, subject to
such reasonable regulations as the Warrant Agent may prescribe, it shall
register the names and addresses of Holders of Units evidenced by Unit
Certificates in registered form and the certificate numbers and denominations
of such Unit Certificates. The Warrant Agent shall also register in the Unit
Register all exchanges and transfers of Units evidenced by Unit Certificates.

                  At the Separation Date or as soon thereafter as practicable,
the Warrant Agent shall make appropriate notations in the Unit Register to
reflect the expiration of the Units and shall take such steps as it deems
necessary or desirable to close the Unit Register. The Unit Register shall be
in written form or in any other form capable of being converted into written
form within a reasonable time. The Warrant Agent shall provide the Company and
Intelligent Polymers Limited with access to the Unit Register during normal
business hours and, if so requested by the Company or Intelligent Polymers
Limited, shall promptly provide them with a copy of the Unit Register.

                  13. Registration of Warrants and Warrant Shares.

                  (a) Registration of Warrants. The Warrants have been
registered under the Act pursuant to the Registration Statement on Forms F-1
and F-3 (Registration Nos. 333-35833 and 333-35839), as declared effective by
the SEC on October , 1997, and the securities and blue sky laws of certain
states.

                  (b) Filings with the SEC and Registration of the Warrant
Shares. The Company covenants and agrees: No later than October 1, 1999, the
Company shall file a registration statement covering the Warrant Shares
issuable upon exercise of the Warrants, use its best efforts to cause such
registration statement to be declared effective by the SEC and use its best
efforts to register or qualify the Warrant Shares issuable upon exercise of the
Warrants under the securities or Blue Sky laws of each U.S. jurisdiction in
which such registration or qualification is necessary, provided that the
Company shall not be required to (i) qualify to do business as a broker-dealer
in any jurisdiction where it is not then so qualified or (ii) take any action
which would subject it to general service of process or to taxation in any
jurisdiction where it is not then so subject. The Company shall use its best
efforts to cause such registration statement to remain effective through
September 30, 2002 or until all Warrants have been exercised.



<PAGE>   10
                                      10




                  (c) Expenses. The Company will pay all expenses incurred by
the Company in complying with this Section 14, including, without limitation,
(i) all registration and filing fees, (ii) all printing expenses, (iii) all
fees and disbursements of counsel and independent public accountants for the
Company, (iv) all Blue Sky fees and expenses (including fees and expenses of
counsel in connection with any Blue Sky surveys), and (v) the entire expense of
any special audits incident to or required by any such registration.

                  (d) Listings. The Company covenants to make commercially
reasonable efforts to arrange for the Warrants and all Common Shares issuable
upon exercise of the Warrants to be listed on the New York Stock Exchange after
the Separation Date. Any such listing or quotation will be at the Company's
expense.

                  14. Warrant Agent. The Warrant Agent hereby accepts the
agency established by this Agreement and agrees to perform only the duties and
obligations explicitly imposed by this Agreement upon the following terms and
conditions, all of which the Company and each Holder by acceptance of a Warrant
Certificate, shall be bound:

                  (a) Correctness of Statements. The statements contained
herein and in the Warrant Certificates shall be taken as statements of the
Company, and the Warrant Agent shall not be liable for, nor does it assume, any
responsibility for the correctness of any of them except for such statements
which describe the Warrant Agent or actions it takes or to be taken by it. The
Warrant Agent assumes no responsibility with respect to the distribution of the
Warrant Certificates except as otherwise provided.

                  (b) Breach of Covenants. The Warrant Agent shall not be
responsible for any failure of the Company to comply with any of the covenants
or conditions contained in this Agreement or in the Warrant Certificates.

                  (c) Reliance on Counsel. The Warrant Agent may select and
consult at any time with counsel satisfactory to it (who may be counsel for the
Company) and the Warrant Agent shall incur no liability or responsibility to
the Company or to any Holder in respect of any action taken, suffered or
omitted by it hereunder in good faith and in accordance with the opinion or the
advice of such counsel provided the Warrant Agent shall have exercised
reasonable care in the selection and continued employment of such counsel.

                  (d) Reliance on Documents. The Warrant Agent shall incur no
liability or responsibility to the Company or to any Holder for any action
taken in reliance on any Warrant Certificate, certificate of shares, notice,
resolution, waiver, consent, order, certificate or other paper, document or
instrument believed by it to be genuine or to have been signed, sent or
presented by the proper party or parties.

<PAGE>   11
                                      11




                  (e) Company Responsibilities. The Company agrees to perform,
execute, acknowledge and deliver or cause to be performed, executed,
acknowledged and delivered all further and other acts, instruments and
assurances as may reasonably be required by the Warrant Agent for carrying out
or performing by the Warrant Agent any of the provisions of this Agreement.

                  (f) Warrant Agent Compensation. The Company agrees to pay the
Warrant Agent reasonable compensation for all services rendered by the Warrant
Agent in the execution of this Agreement, to reimburse the Warrant Agent for
all reasonable expenses (including reasonable fees and expenses of its
counsel), taxes and governmental charges and other charges of any kind and
nature incurred by the Warrant Agent in the execution of this Agreement and to
indemnify the Warrant Agent and save it harmless against any and all losses,
expenses or liabilities, including judgments, costs and counsel fees, arising
out of or in connection with its agency under this Agreement, except as a
result of its gross negligence or bad faith.

                  (g) Legal Proceedings. The Warrant Agent shall be under no
obligation to institute any action, suit or legal proceeding or to take any
other action likely to involve expense unless the Company or one or more
Holders shall furnish the Warrant Agent with reasonable security and indemnity
for any costs and expenses which may be incurred, but this provision shall not
affect the power of the Warrant Agent to take such action as it may consider
proper, whether with or without any such security or indemnity. All rights of
action under this Agreement or under any of the Warrants may be enforced by the
Warrant Agent without the possession of any of the Warrant Certificates or the
production thereof at any trial or proceeding relative thereto, and any such
action, suit or proceeding instituted by the Warrant Agent shall be brought in
its name as Warrant Agent and any recovery of judgment shall be for the ratable
benefit of the holders of the Warrants, as their respective rights or interests
may appear.

                  (h) Other Transactions. The Warrant Agent and any
shareholder, director, officer or employee of it may buy, sell or deal in any
of the Warrants or other securities of the Company or become pecuniarily
interested in any transaction in which the Company may be interested, or
contract with or lend money to the Company or otherwise act as fully and freely
as though it were not the Warrant Agent under this Agreement. Nothing herein
shall preclude the Warrant Agent from acting in any other capacity for the
Company and for any other legal entity.

                  (i) Liability of Warrant Agent. The Warrant Agent shall act
hereunder solely as agent for the Company and its duties shall be determined
solely by the provisions hereof. The Warrant Agent shall not be liable for
anything which it may do or refrain from doing in connection with this
Agreement except for its own gross negligence or bad faith.

                  (j) Certification for the Benefit of Warrant Agent. Whenever
in the performance of its duties under this Agreement the Warrant Agent shall
deem it necessary or 

<PAGE>   12
                                      12



desirable that any matter be proved or established or that any instructions
with respect to the performance of its duties hereunder be given by the Company
prior to taking or suffering any action hereunder, (for example, establishment
of the Exercise Price or any adjustment thereto), such matter (unless other
evidence in respect thereof be herein specifically prescribed) may be deemed to
be conclusively proved and established, or such instructions may be given, by a
certificate or instrument signed by the President, Chief Executive Officer, or
any Vice President, or the Secretary of the Company and delivered to the
Warrant Agent. Such certificate or instrument may be relied upon by the Warrant
Agent for any action taken or suffered in good faith by it under the provisions
of this Agreement; but in its discretion the Warrant Agent may in lieu thereof
accept other evidence of such matter or may require such further or additional
evidence as it may deem reasonable.

                  (k) Company Instructions. Except as authorized and directed
by the Company, the Warrant Agent shall not at any time be under any duty or
responsibility to any Holder to make or cause to be made any adjustment of the
Exercise Price or the number of Warrant Shares or other securities or property
deliverable as provided in this Agreement, to determine whether any facts exist
which may require any such adjustment, with respect to the nature or extent of
any such adjustments when made, or with respect to the method employed in
making the same. The Warrant Agent shall not be accountable with respect to the
validity or value or the kind or the amount of any Warrant Shares or of any
security or property which may at any time be issued or delivered upon the
exercise of any Warrant or, at the expiration of the Exercise Period, for any
unexercised Warrant or with respect to whether any Warrant Shares or other
securities which when issued will be validly issued and fully paid and
nonassessable. In no event shall the Warrant Agent be liable for consequential,
indirect or special damages, loss of profits or loss of business even if
informed of the possibility of such damages by the Company, a Warrant Holder or
a third party and regardless of the form of action.

                  15. Change of Warrant Agent. The Warrant Agent may at any
time resign as Warrant Agent hereunder by written notice of its election
delivered to the Company, such resignation to take effect upon the appointment
of a successor warrant agent and its acceptance of such appointment as
hereinafter provided. If the Warrant Agent shall resign or become incapable of
acting as Warrant Agent, the Company shall appoint a successor to such Warrant
Agent. If the Company shall fail to make such appointment within a period of 30
days after it has been notified in writing of such resignation or incapacity by
the Warrant Agent or by a Holder, then the Warrant Agent or a Holder of any
Warrant may apply to any court of competent jurisdiction for the appointment of
a successor to the Warrant Agent. In addition, the Company shall have the right
to terminate the obligations of the Warrant Agent hereunder upon 30 days prior
written notice. Pending appointment of a successor to such Warrant Agent in any
such case, either by the Company or by a court, the duties of the Warrant Agent
shall be carried out by the Company. Any successor warrant agent, whether
appoint by the Company or by a court, shall be a bank or trust company, in good
standing, located in the United States, and must have at the time of its
appointment as warrant agent a combined capital and surplus of at least


<PAGE>   13
                                      13



$100,000,000. After appointment, a successor warrant agent shall be vested with
the same powers, rights, duties and responsibilities as if it had been
originally named as warrant agent without further act or deed; but the former
warrant agent shall deliver and transfer to the successor warrant agent any
property held at the time by it hereunder and execute and deliver any further
assurance, conveyance, act or deed necessary for the purpose. Failure to give
any notice provided for in this Section 16, however, or any defect herein,
shall not affect the legality or validity of the appointment of a successor
warrant agent.

                  16. Merger, Consolidation or Change of Name of Warrant Agent.
Any corporation into which the Warrant Agent may be merged or with which it may
be consolidated, or any corporation resulting from any merger or consolidation
to which the Warrant Agent shall be a party, or any corporation succeeding to
the corporate trust business of the Warrant Agent, shall be the successor to
the Warrant Agent hereunder without the execution or filing of any paper or any
further act on the part of any of the parties hereto, provided that such
corporation would be eligible for appointment as a successor warrant agent
under the provisions of Section 16 hereof. In case at the time such successor
to the Warrant Agent shall succeed to the agency created by this Agreement, and
in case at that time any of the Warrants shall have been countersigned but not
delivered, any such successor to the Warrant Agent may adopt the
countersignature of the predecessor warrant agent and deliver such Warrant so
countersigned; and in case at that time any of the Warrants shall not have been
countersigned, any successor to the Warrant Agent may countersign such Warrants
either in the name of the predecessor warrant agent or in the name of the
successor warrant agent; and in all such cases such Warrants shall have the
full force and effect provided in the Warrants and in this Agreement.

                  In the case at any time the name of the Warrant Agent shall
be changed and at such time any of the Warrants shall have been countersigned
but not delivered, the Warrant Agent may adopt the countersignature under its
prior name and deliver Warrants so countersigned; and in case at that time any
of the Warrants shall not have been countersigned, the Warrant Agent may
countersign such Warrants either in its prior name or in its changed name; and
in all such cases such Warrants shall have the full force and effect provided
in the Warrants and in this Agreement.

                  17. Notice to Company, Warrant Agent and Holders.  Any notice 
pursuant to this Agreement to be given by the Company or by any Holder to the
Warrant Agent shall be sufficiently given if delivered by hand or by reputable
overnight delivery service or courier, or five days after mailing by first
class or registered mail, postage prepaid, addressed (until another address is
filed in writing by the Warrant Agent with the Company) to the Warrant Agent as
follows:

                  ----------------------- 
                  ----------------------- 
                  -----------------------

                  Notices and other communications to be given to the Company
by any Holder or the Warrant Agent shall be deemed sufficiently given if
delivered by hand or by reputable overnight delivery service or courier, or
five days after mailing by first class or registered mail, postage prepaid,
addressed (until another address is filed in writing by the Company with the
Warrant Agent) to the Company as follows:

                  Biovail Corporation International
                  2488 Dunwin Drive
                  Mississauga, Ontario, Canada
                  L5L 1J9
                  Attention:  Chief Financial Officer

                  Notices and other communications to be given to any Holder
shall be deemed sufficiently given if delivered by hand or by overnight
delivery service or courier or five days after mailing by first class or
registered mail, postage prepaid, addressed (until another address is filed in
writing by the Holder with the Warrant Agent and the Company) in the name and
to the address of such Holder appearing on the records of the Warrant Agent or
the Company.

                  18. Use of Agents. The Warrant Agent may execute and exercise
any of its rights and powers hereby vested in it or perform any duty hereunder
either itself or by or through its agents or attorneys and the Warrant Agent
shall not be answerable or accountable for any act, default, neglect or
misconduct of such agents or attorneys; provided, however, reasonable care was
exercised in the selection thereof.

                  19. Purchase of Warrants by the Company.

                  (a) The Company shall have the right to purchase or otherwise
acquire Warrants at such times, in such manner and for such consideration as it
may deem appropriate.

                  (b) In the event the Company shall purchase or otherwise 
acquire Warrants, the same shall thereupon be delivered to the Warrant Agent
and be cancelled by it and retired. The Warrant Agent shall cancel any Warrant 
surrendered for exchange, substitution, transfer or exercise in whole or in 
part.

                  20. Miscellaneous.

                  (a) Statements on Warrants. Irrespective of any adjustments
in the Exercise Price or the number or kind of shares purchasable upon the
exercise of the Warrants, Warrants theretofore or thereafter issued may
continue to express the same price and number and kind of shares as are stated
in the Warrants initially issuable pursuant to this Agreement.

                                      15


                  (b) Supplements and Amendments. The Company and the Warrant
Agent may from time to time supplement or amend this Agreement without the
approval of any Holder in order to cure any ambiguity or to correct or
supplement any provision contained herein which may be defective or
inconsistent with any other provision herein, or to make any other provisions
in regard to matters or questions arising hereunder which the Company and the
Warrant Agent may deem necessary or desirable and which shall not adversely
affect the interest of the Holders.

                  (c) Successors. All covenants and provisions of this
Agreement by or for the benefit of the Company or the Warrant Agent shall bind
and inure to the benefit of their respective successors and assigns hereunder.

                  (d) Termination.     This Agreement shall terminate on the 
fifteenth day following the earlier to occur of (i) the Expiration Date and
(ii) the date on which there remain no Warrants outstanding.

                  (e) Facsimile Signature.  The Warrant Certificates and any 
Warrant Certificates that replace the Warrant Certificates may be executed by
the Company in facsimile.

                  (f) Benefits of This Agreement. Nothing in this Agreement
shall be construed to give to any person or corporation other than the Company,
the Warrant Agent and the Holders any legal or equitable right, remedy or claim
under this Agreement, and this Agreement shall be for the sole and exclusive
benefit of the Company, the Warrant Agent and the Holders.

                  (g) Governing Law. This Agreement and the Warrants issued
hereunder shall be construed in accordance with the laws of the State of New
York applicable to contracts executed in that state by residents of that state
to be performed wholly within that state.

                  (h) Counterparts. This Agreement may be executed in any
number of counterparts each of which so executed shall be deemed to be an
original, but such counterparts shall together constitute but one and the same
instrument.

                  (i) Headings. The descriptive headings of sections of this

(notwithstanding any notation of ownership or other writing made hereon by
anyone) for the purpose of exercise of the Warrant and for all other purposes,
and neither the Company nor the Warrant Agent shall be affected by any notice
to the contrary.

                 Upon receipt by the Warrant Agent of evidence satisfactory to
it of the loss, theft, destruction or mutilation of this Warrant Certificate

October [  ], 1997

Biovail Corporation International
2488 Dunwin Drive
Mississauga Ontario
L5L 1J9

Attention:  Mr. Robert A. Podruzny

Dear Sirs:

I have acted as Canadian in-house general counsel to Biovail Corporation
International ("Biovail") in connection with the proposed issue of up to
3,737,500 units (the "Units"), each Unit consisting of 1 Common Share, with a
par value of $0.01 each, of Intelligent Polymers Limited and one warrant
("Warrant") to acquire one common share without par value of Biovail.

I refer to the registration statement and the related prospectus (respectively,
the "Registration Statement" and the "Prospectus") first filed on September 17,
1997 by Biovail under the Securities Act, 1933 (as amended) (the "Act") in
respect of the foregoing.

In connection with this opinion, I have examined and have assumed the truth and
accuracy of the contents of such documents and certificates of officers of and
advisers to Biovail and of public officials as to factual matters and have
conducted such searches in public registries in Canada as I have deemed
necessary or appropriate for the purposes of this opinion but I have made no
independent investigation regarding such factual matters.  In my examination I
have assumed the genuineness of all signatures, the authenticity of all
documents submitted to us as originals, the conformity to original documents of
all documents submitted to us as certified or photostatic copies and the
authenticity of the originals of such documents.  I have





<PAGE>   2

                                      -2-


further assumed that none of the resolutions and authorities of the
shareholders or directors of Biovail upon which I have relied has been varied,
amended or revoked in any respect or has expired and that the Warrants and the
common shares of Biovail will be issued in accordance with such resolutions and
authorities and as contemplated by and described in the Registration Statement,
in the Prospectus and in the Underwriting Agreement, a copy of which is
attached as an exhibit to the Registration Statement.  I further assume that
Biovail will comply with its obligations under and the representations and
warranties contained in the Underwriting Agreement and in all of the other
agreements which are attached as exhibits to the Registration Statement.

I am admitted to practice law only in the Province of Ontario, Canada and
accordingly express no opinion on the laws of any jurisdiction other than the
laws of Ontario and the laws of Canada as they relate to the matters therein,
in force as at the date hereof. In giving this opinion I have relied as to
certain matters governed by New York law on the advice of Cahill Gordon &
Reindel, U.S. Counsel to the Companies.

I assume the transactions contemplated in the Registration Statement and in the
Prospectus are lawful under the laws of the United States, the relevant states
thereof including New York State and all other applicable laws (if any).  Since
the transactions contemplated by the Registration Statement are governed by the
laws of jurisdictions outside Canada, we express no opinion herein as to
matters of enforceability.

Based upon the foregoing I am of the opinion that:

           (i)    Biovail is duly incorporated and validly existing
                  under the laws of Ontario, Canada.

           (ii)   The issue of the Warrants has been duly authorised by
                  Biovail.

           (iii)  The Common Shares issuable upon exercise of the
                  Warrants have been duly authorised and, when issued
                  upon such exercise and upon payment of the exercise
                  price in accordance with the terms of the Warrant
                  Agreement, will be duly authorised, legally issued,
                  fully paid and non-assessable.

                                     - 3 -

I hereby consent to the filing of this opinion with the United States
Securities and Exchange Commission as an exhibit to the Registration Statement.

This opinion is to be construed in accordance with and governed by the laws of
the Province of Ontario.

Yours very truly,

Kenneth C. Cancellara

Dear Sirs:

     We have acted as counsel to Biovail Corporation International, a
company established under the laws of Ontario, Canada ("Biovail"), and
Intelligent Polymers Limited, a company established under the laws of
Bermuda ("Intelligent Polymers"; together with Biovail, the "Registrants"),
in connection with the offering of units (the "Units"), each Unit consisting
of one Common Share, par value $.01, of Intelligent Polymers and one Warrant
to purchase one Common Share, no par value, of Biovail.  The Registration
Statement on Form F-1/F-3 (Nos. 333-35833 and 333-35839) relating to the
Units was filed with the Securities and Exchange Commission (the
"Commission") by the Registrants under the Securities Act of 1933, as
amended (the "Securities Act") on October 6, 1997, (such registration
statement, as amended at the time it is declared

<PAGE>   2

effective, is herein referred to as the "Registration Statement" and
the prospectus included in the Registration Statement is herein referred to
as the "Prospectus").

     In connection with this opinion, we have examined and have assumed the
truth and accuracy of the contents of such documents and certificates of
officers of and advisers to Biovail and of public officials as to factual
matters as we have deemed necessary or appropriate for the purposes of this
opinion but we have made no independent investigation regarding such factual
matters.  In our examination we have assumed the genuineness of all signatures,
the authenticity of all documents submitted to us as originals, the conformity
to original documents of all documents submitted to us as certified or
photostatic copies and the authenticity of the originals of such documents.  We
have further assumed that none of the resolutions and authorities of the
shareholders or directors of Biovail upon which we have relied has been varied,
amended or revoked in any respect or has expired and that the Warrants and the
common shares of Biovail will be issued in accordance with such resolutions and
authorities and as contemplated by and described in the Registration Statement,
in the Prospectus and in the Underwriting Agreement, a copy of which is
attached as an exhibit to the Registration Statement.  We further assume that
Biovail will comply with its obligations under and the representations and
warranties contained in the Underwriting Agreement and in all of the other
agreements which are attached as exhibits to the Registration Statement.

     We are of the opinion that when duly executed, issued and delivered by
Biovail and countersigned by the Warrant Agent and when payment of the purchase
price for the Units has been made, the Warrants will be legally issued and will
constitute valid and binding obligations of Biovail.

     We hereby consent to the filing of this opinion with the Commission as an
exhibit to the Registration Statement and to the reference to our firm under
each of the captions "Taxation-United States Taxation" and "Legal Matters" in
the Registration Statement and related Prospectus.  In consenting to such
reference, we do not admit to being experts within the meaning of the
Securities Act or the rules and regulations of the Commission thereunder, as we
have not certified any part of the Registration Statement.

                                             Very truly yours,

one common share of Biovail Corporation International ("Biovail").

     In our capacity as Bermuda counsel to Intelligent Polymers, we
participated in the preparation of the registration statement ("Registration
Statement") on Form F-1/F3 registration nos.      and with respect to the Units
which was filed with the Securities and Exchange Commission ("Commission")
under the Securities Act of 1933 as amended ("Act") of the United States of
America together with all exhibits to the Registration Statement and the forms
of prospectus (the "Prospectus") also filed with the Commission together with
all amendments thereto duly filed in accordance with the Act.

     For the purposes of giving this opinion, we have examined and relied upon
the Registration Statement.  We have also reviewed a copy of the memorandum of
association and bye-laws of Intelligent Polymers certified as a true copy
thereof by the secretary of Intelligent Polymers on September   , 1997, minutes
of meetings of Intelligent Polymers's board of directors and minutes of
shareholders' meetings and such other documents and made such enquiries as to
questions of law as we have deemed necessary in order to render the opinion set
forth below:

We have assumed:


<PAGE>   2

                                      -2-



(i)   the genuineness and authenticity of all signatures and the
      conformity to the originals of all copies (whether or not
      certified) of all documents examined by us and the authenticity
      and completeness of the originals from which such copies were
      taken;

(ii)  the correctness, accuracy and completeness of all factual
      representations made in the Registration Statement and in the
      other documents which we have reviewed; and

(iii) that there is no provision of the law of any jurisdiction, other
      than Bermuda, which would have any implication in relation to the
      opinions expressed herein.

     We have made no investigation of and express no opinion in relation to the
laws of any jurisdiction other than Bermuda.  This opinion is to be governed by
and construed in accordance with the laws of Bermuda and is limited to and is
given on the basis of the current law and practice in Bermuda.

     The term "non assessibility" is not a legal concept under Bermuda law, but
when we describe shares as being "non assessable" (see paragraph 2 below) we
mean with respect to the shareholders of a company, in relation to fully paid
shares of the company and subject to any contrary provision in any agreement in
writing between the company and any one of its shareholders holding such shares
but only with respect to such shareholder, that such shareholder shall not be
bound by an alteration to the memorandum of association or the bye-laws of that
company after the date upon which they became such shareholders, if and insofar
as the alteration requires them to take, or subscribe for additional shares, or
in any way increases their liability to contribute to the share capital of, or
otherwise pay money to, such company.

     On the basis of and subject to the foregoing, we are of the opinion that:

   1. Intelligent Polymers has been duly incorporated and is an existing limited
liability exempted company under the laws of Bermuda, with corporate power and
corporate authority to own, lease and operate its properties and conduct its
business as described in the Prospectus.

<PAGE>   3

    2. The Common Shares to be sold by Intelligent Polymers as a component of
the Units have been duly authorised, legally issued and, when duly paid for,
will be fully paid and non-assessable; such Intelligent Polymers Common Shares
are not subject to the pre-emptive rights of any shareholder of Intelligent
Polymers; all corporate action required to be taken for the authorization,
issue and the sale of the Intelligent Polymers Common Shares has been validly
taken and on personal liability will attach to holder thereof solely by reason
of the ownership thereof.

    3. The statements in the Registration Statement and Prospectus under the
caption "Taxation-Bermuda Tax Considerations" have been prepared and reviewed
by us and are correct in all material respects.

    4. We hereby consent to the filing of this opinion with the Commission and
as an exhibit to the Registration Statement and Prospectus and to the reference
to this Firm under the captions "Enforceability of Civil Liabilities under
United States Federal Securities Laws", "Taxation-Bermuda Tax Considerations"
and "Legal Matters".

                                            Yours faithfully,


                                            Conyers Dill & Pearman

<PAGE>   12

                                      -12-

 
     tests and studies as BLI may from time to time during the Term of this
     Agreement delegate or assign to BCI.  BCI agrees to perform such of the
     activities, tests and studies as may be delegated or assigned to it by
     BLI.

2.5  Each of BLI and BCI agrees that Polymer may enforce the terms of this
     Agreement directly against BCI with respect to the performance of any
     activity, test or study delegated or assigned to BCI by BLI as if Polymer
     had itself engaged BCI to carry out such activity, test or study.  Polymer
     accepts the performance of any such activity, test or study by BCI as
     performance by BLI itself, and acknowledges that BCI may fulfil any of the
     obligations of BLI under this Agreement.  Each of BLI and BCI fully and
     unconditionally guarantees the performance by the other of its obligations
     under this Agreement.

   PRODUCT DEVELOPMENT PRIORITIES

2.6  Polymer and BLI shall negotiate in good faith, as soon as reasonably
     possible after the Effective Date, to determine the relative priorities
     for the Development of each of the Products.  Biovail shall then develop
     budgets for each of the stages of Product Development for each Product,
     consistent with these priorities.

   PRODUCT DEVELOPMENT PROGRAM

2.7  For each of the Products, BLI shall prepare and submit to Polymer a
     Product Development Program consistent with the priorities and budgets
     established under paragraph 2.6.  BLI shall diligently perform or cause
     BCI or any other qualified person to perform the tasks and activities set
     out in the Product Development Program.

2.8  Each of BLI, BCI and Polymer shall diligently carry out their respective
     obligations under the Product Development Program and shall report any
     significant deviations therefrom to the Other in a timely manner.

2.9  BLI shall produce all information and data necessary to file any IND or
     NDA for any Product developed hereunder.

    MODIFICATIONS TO SCHEDULING AND PRIORITIES

2.10 Polymer acknowledges that technological and commercial uncertainties may
     make it necessary for BLI to modify or change the relative priorities
     assigned to Product Development Programs pursuant to paragraph 2.6. BLI
     shall notify Polymer of any such changes or modifications planned by BLI.
     If the Parties are unable to agree on those proposed changes or
     modifications, BLI may, in its sole discretion, determine from time to
     time:

     (a)  the resources of BLI and BCI (whether facilities,
          equipment, personnel or otherwise) to be devoted or dedicated to
          the Development of each Product;

     (b)  the priority to be given to any part of a Product
          Development Program;

     (c)  the allocation of the resources of BLI or BCI (whether
          facilities, equipment, personnel or otherwise) that are to be
          made available to Polymer for each of the stages of any Product
          Development Program; and

     (d)  the portion of Available Funds allocated to each
          activity within the budget for each individual Product under this
          Agreement.

2.11 Polymer acknowledges that each of BLI and BCI has and shall have from
     time to time during the term of this Agreement other projects in various
     stages of development for their own accounts and for the account of third
     parties, as well as commitments to third parties to develop other
     products. Polymer acknowledges that such projects and commitments shall
     require the expenditure of BLI's and BCI's own funds and the commitment of
     BLI's and BCI's resources to development projects which do not involve the
     Products or Polymer.  Nothing in this Agreement requires BLI or BCI to
     devote any designated or minimum amount of resources to the Products.  The
     development of the Products shall be subject to the provisions of
     paragraph 2.10.

2.12 Notwithstanding the provisions of paragraph 2.11 above, if at any time
     during the Term of this Agreement BLI is persistently unable or unwilling
     to devote its own re-


<PAGE>   14

                                      -14-


     sources or those of BCI to the Products in the manner contemplated by this
     Agreement and in a manner consistent with reasonable commercial practice,
     Polymer may, upon 60 days' written notice to BLI, and upon BLI's failure
     to take, or to agree to take, within such period, reasonable steps to
     remedy such situation, engage other Persons to continue the Development of
     the Products and to utilize any of the Available Funds therefor.

    THIRD-PARTY AGREEMENTS

2.13 Polymer acknowledges that BLI may perform research and development work
     with respect to any Excluded Product in any country for third parties or
     for BLI's own account, or with respect to any other products, using the
     Biovail Technology, any of the data or information created or generated
     during the Development of any of the Products or any other technology
     available to Biovail.  All such research and development work shall be
     paid for with funds other than the Available Funds.  Any additional Patent
     Rights, Know-how or other benefits derived from such research and
     development work shall be the absolute and exclusive property of BLI

2.14 BLI may, in the Development of the Products, use any intellectual
     property or technology of any third person that BLI is lawfully entitled
     to use, and may in its sole discretion attempt to obtain any other rights
     to use, or licenses under, any intellectual property or technology of any
     third person that BLI determines to be necessary or useful to enable BLI
     to fulfil its obligations under this Agreement.

    SUBSTITUTED PRODUCTS

2.15 If at any time during the Term of this Agreement:

     (a)  BLI determines that the Development of any Product
          cannot be completed within the priorities and budgets established
          under paragraph 2.6;

     (b)  any Applicafion for Regulatory Approval for any Product
          is not filed or appears unlikely to be filed within three (3)
          years of the Effective Date;


<PAGE>   15

                                      -15-


     BLI shall so notify Polymer.  BLI and Polymer shall co-operate in good
     faith to identify new products to be added to Schedule 1.37, and to
     modify the list of priorities and budgets accordingly.  If BLI and
     Polymer are unable to agree on such new products or modified
     priorities, BLI shall continue to Develop the remaining Products in
     accordance with the Terms of this Agreement.

    OTHER PRODUCTS

2.16 Polymer shall have the right from time to time, with the consent of BLI,
     to add other Products (the "Designated Products") to Schedule 1.37 to this
     Agreement for Development hereunder; provided that:

     (a)  The Board of Directors of Polymer shall (i) recommend
          in writing that such other Products be developed hereunder and
          (ii) acknowledge in writing that Polymer is willing to apply a
          portion of the Available Funds to the development of such other
          Products;

     (b)  At BLI's request, Polymer shall irrevocably agree to
          expend sufficient funds from the Available Funds to develop such
          other Products pursuant to the terms of this Agreement.

2.17 Upon the compliance by Polymer with the requirements of paragraph 2.16,
     the Designated Products shall be added to Schedule 1.37 which shall be
     deemed to be amended accordingly.

    FAILURE TO DEVELOP

2.18 In no event shall BLI or BCI be liable to Polymer for (a) any partial or
     total failure to develop any Product in the manner anticipated by BLI, BCI
     or Polymer or (b) any result or outcome or evaluations, trials, tests or
     decisions (by BLI, BCI or Polymer) relating to Product Development.


<PAGE>   16

                                      -16-


    NO WARRANTIES

2.19 Each of BLI and BCI disclaims any express or implied warranty (i) that
     the use of any Products will be free from claims of patent infringement,
     interference or unlawful use of proprietary information of any third party
     or infringement of any intellectual property rights generally and (ii) as
     to the accuracy, reliability, technological or commercial value,
     comprehensiveness or merchantability of such Products or their suitability
     or fitness for any purpose including, without limitation, the design,
     development, manufacture, use or sale of such Products.  Each of BCI and
     BLI disclaims all other warranties of whatever nature, express or implied.

    DEDICATION OF FUNDS

2.20 Polymer acknowledges that all of the Available Funds shall be paid to BLI
     in accordance with the terms of this Agreement to be used by BLI to the
     extent necessary to complete the Development of the Products.  Polymer
     shall not, except as provided in paragraphs 2.12, 7.4 and 7.15, enter into
     any agreement or understanding with, or make any payment to, any Person
     that is not a Subsidiary or Affiliate of BLI, with respect to the
     development of, or to the making, testing or studying of any Product,
     without the prior written consent of BLI.

    PROPERTY OF BLI

2.21 All INDs, NDAs, and NDAs filed hereunder, and all information, data and
     technology developed pursuant to the terms of this Agreement, shall remain
     the property of BLI.  BLI shall, at the request of Polymer on reasonable
     notice to BLI, give Polymer reasonable access to, and the right to use,
     all such documents, information, data and technology to the extent
     necessary to enable Polymer to fulfil its obligations and exercise its
     rights under this Agreement.

<PAGE>   17

                                      -17-


     ment Program shall be the property of BLI, and shall 
     not be used by Polymer except for the purpose of Mar
     keting the Product in accordance with the terms of the 
     license granted by paragraph 7.1 of this Agreement.
     None of such data or information may be used by Polymer 
     for or in association with the Manufacture or Marketing 
     of any other product.
                 
3. REGISTRATION OF PRODUCTS


3.1  BLI shall prepare and file any IND necessary to enable BLI and BCI to
     carry out their obligations under this Agreement for any Product.

   NDAS AND ANDAS

3.2  As soon as reasonably possible after completion of the necessary tests
     and studies for any Product, BLI shall prepare an Application for
     Regulatory Approval of that Product, in the form of an NDA or ANDA as
     required.  BLI shall be solely responsible for all aspects of the
     prosecution of such NDA or ANDA.  BLI shall not, however, be liable or
     responsible to Polymer in the event that any NDA or ANDA is not approved
     or if there is any delay (whether foreseen or unforeseen) in obtaining
     Regulatory Approval of any Product.

   REGISTRATION PROCEDURES

3.3  BLI shall keep Polymer fully advised of all steps taken by BLI, and by
     BCI on behalf of BLI, the prosecution of each Application for Regulatory
     Approval referred to in paragraph 3.2 above, and of the progress of each
     Application for Regulatory Approval.  BLI shall provide to Polymer regular
     reports in respect of each such Application for Regulatory Approval
     undertaken by BLI.  In particular, BLI shall advise Polymer of the dates
     of submission and approval of INDs, NDAs, and ANDAs.

3.4  BLI shall have the right to select (in its reasonable discretion) the
     order in which Applications for Regulatory Approval for any Product are
     filed with the FDA but shall be guided in its choice by priorities
     determined under paragraph 2.6 and by the marketing and sales needs of
     Polymer as communicated by Polymer to


<PAGE>   18

                                      -18-


     BLI in discussions and consultations between Polymer and BLI from time to
     time.

   COSTS

3.5  The costs and expenses of any and all regulatory filings and proceedings
     relating to the FDA or any other government authority shall be borne
     solely by Polymer, and shall be paid for by Polymer, or reimbursed to BLI,
     as the case may be, from the Available Funds.

4. ADDITIONAL FUNDING

4.1  Polymer shall deliver to BLI on or before the tenth (10) day of each
     month a statement specifying the Available Funds spent to date and the
     amount of Available Funds remaining.  At any time that the amount of
     Available Funds falls below three million dollars (US Funds),
     (US$3,000,000), Polymer shall deliver to BLI a Financial Notice certifying
     that amount.

4.2  No later than 90 days after delivery of the Financial Notice, to the
     extent BLI has not exercised the Purchase Option or extended the
     termination date of the Purchase Option or extended the termination date
     of the Purchase Option in each case as provided herein, Polymer and BLI
     will commence good faith negotiations as to any terms on which BLI might
     provide additional funding for any or all of the Products, taking into
     account relevant issues including but not limited to the amount and timing
     of such funding, possible alterations in the terms of the Biovail Option
     if the Biovail Option has not yet been exercised or the possibility of

     paragraph 4.2 within sixty (60) days after the commencement of such
     negotiations, BLI shall grant to Polymer an exclusive License under all
     remaining Products under the Biovail Technology (as reasonably agreed to
     by BLI and Polymer) to use, manufacture (except where such right is held
     by a third party), obtain manufacturing for, sell or otherwise market such
     products in the Territory for the License Period.  BLI shall in addition
     grant to Polymer an exclusive License in the Territory for all of its
     patent rights, other intellectual property and supply arrangements
     relating thereto (as reasonably agreed to by BLI and Polymer as being
     necessary to develop further any such product) for the License Period, and
     a nonexclusive, royalty-free license after the expiry of the License
     Period.  The provisions of Articles 3, 7, 8, 9 and 11 of this Agreement
     shall not apply to any Products in respect of which BLI grants to Polymer
     a License under the Biovail Technology pursuant to this paragraph.

5. PAYMENT FOR PRODUCT DEVELOPMENT

   INITIAL PAYMENT

5.1  Polymer shall pay to BLI, out of Available Funds, on the date of closing

                                      -20-


     and the amount to be charged to Polymer for that work.  Any difference
     between the amount paid in advance by Polymer and the amount to be charged
     to Polymer shall be paid by Polymer to BLI within thirty (30) days of the
     receipt by Polymer of such detailed report, or credited to Polymer on the
     next quarterly payment, as the case may be, provided, however, that the
     aggregate of all such amounts paid shall not exceed the aggregate amount
     of Available Funds.

5.3  The amounts to be charged to and paid by Polymer pursuant to this
     Agreement are the full amounts of the Development Costs, billed to Polymer
     at a rate of BLI's or BCI's fully absorbed costs plus forty-five per cent
     (45%) of those costs, except for costs which are associated with payments
     to third party contract research organizations for services performed
     under this Agreement, which shall be billed at BLI's or BCI's actual cost
     plus fifteen per cent (15%) of those costs.


   SUFFICIENCY OF FUNDS; ETC.

5.4  Neither Polymer nor BLI makes any warranty, express or implied, that the
     Available Funds will be sufficient for the completion of the Product
     Development work for any of the Products.

          Product Development costs for the Additional Product incurred by
          BLI and BCI during the months of May and June 1997; and

     (b)  an amount calculated in accordance with the method set
          out in paragraph 5.2 for the Product Development costs incurred
          by BLI and BCI between July 1, 1997 and the date of closing of
          the Unit Offering as defined in the Prospectus.


<PAGE>   21

                                      -21-


5.6  Polymer shall set aside and maintain in a separate interest bearing
     account, satisfactory to BLI, the Litigation Reserve and shall use the
     funds in that Litigation Reserve only for the purposes of financing any
     possible litigation against Polymer or against BLI arising from an
     Application for Regulatory Approval of the Additional Product in the
     U.S.A. Polymer shall, at the written request of BLI, provide to BLI an
     accounting of the disposition of any funds from that Litigation Reserve,
     and shall promptly reimburse BLI from the Litigation Reserve for any
     expenses incurred by BLI relating to any such litigation.

5.7  Biovail shall have full carriage and control of any such litigation, and
     shall be reimbursed by Polymer from the Litigation Reserve, for the cost
     of such litigation, until such time as Biovail, in its sole discretion,
     determines that such carriage and control should be assumed by Polymer.
     Polymer shall, at the request of Biovail, assume such carriage and
     control, and the cost of the litigation.

     and payable within sixty (60) days of the end of March, June, September
     and December with respect to sales of each of the Products in the three
     (3) month periods ending on the last days of March, June, September and

     U.S. dollars, to such bank account as Polymer may designate, subject to
     any requisite exchange controls, or other governmental consent, being
     obtained.  If such consent is not obtained, the royalty shall be paid to
     such other bank account of Polymer or in such other currency (in the
     equivalent of the amount due in U.S. dollars calculated at the mean of the
     buy and sell rates of exchange as quoted to BLI by its main banker at the
     due date for payment or the date of actual payment, whichever is earlier)
     as may be permitted by such exchange control.  BLI shall on payment of
     royalties submit a written statement summarizing on a country by country
     basis the accrual of the royalties in question together with a copy of the
     quotations of the main banker of BLI on the currency rates in question.

     send to Polymer a statement certified by a financial officer of BLI
     disclosing the Net Sales of the Product for the just-ended calendar
     quarter, the total amount of the deductions referred to in paragraph 1.31
     and the royalties due to Polymer.

7.10 BLI, if required so to do by any applicable tax law, may deduct any
     governmental withholding tax required to be deducted by it on payment of
     royalties hereunder but shall account to the relevant tax authorities for
     the sum so deducted and provide Polymer with proof of such payment from
     such authorities.  BLI shall provide reasonable assistance to Polymer in
     securing any benefits available to Polymer with respect to governmental
     tax withholdings by any relevant law or double tax treaty.

7.11 BLI shall keep at its registered office, and shall cause its Affiliated
     Companies and Licensees to keep, full and accurate records of the sales of
     each of the Products for each country for purposes of compliance with its
     obligations hereunder.  Such records shall be


<PAGE>   25

                                      -25-


         made available following the First Commercial Sale of the Product
         in Canada for inspection by Polymer or an independent certified public
         or chartered accountant of Polymer's choice during normal business
         hours after reasonable notice, up to two (2) years after the
         termination or expiration of this Agreement, and at Polymer's expense.
         Such inspection shall occur no more often than once a year.

    FAILURE TO MARKET

7.12 If any Product is not Muketcd in the U.S.A. by Polymer, an Affiliate of
     Polymer or a Licensee of Polymer within nine (9) months from the date of
     Regulatory Approval of that Product in the U.S.A. (unless the Marketing of
     such Product is impeded or prohibited by any applicable law, regulation or
     order), the License granted to Polymer for that Product for the Territory
     shall be terminated.  BLI shall thereafter, upon written notice to
     Polymer, have the exclusive right to Manufacture, Market and License that
     Product, in and throughout the Territory, subject to the provisions of
     paragraphs 7.3 to 7.11.

7.13 Polymer shall use its reasonable efforts at the request of BLI to cause
     any Licensee of Polymer to enter into a trademark user agreement on the
     terms and conditions reasonably acceptable to BLI for the relevant
     trademark to facilitate the Marketing of the Product by the Licensee under
     BLI's trademark.

    MANUFACTURING

7.14 Notwithstanding any rights or License granted or acquired by Polymer
     under this Agreement, BLI shall have the exclusive right to Manufacture
     each Product for sale in the Territory for a period of five (5) years from
     the date of the first Regulatory Approval for that Product in the
     Territory.

7.15 After the expiry of the five (5) year period referred to in paragraph
     7.14, and as to any Product for which Polymer has acquired Manufacturing
     rights, Polymer may obtain manufacturing of the Product from any qualified
     third party, subject to the provisions of paragraphs 8.19 and 8.21.


<PAGE>   26

                                      -26-


    REGULATORY COMPLIANCE

7.16 Each of BLI and Polymer shall ensure that all Products sold by either of
     them, or by their respective Licensees, shall comply in all respects with
     all applicable laws, regulations and standards affecting the Products, or
     the promotion, labelling and advertising of the Products, and comply with
     all applicable regulatory provisions of any government or Regulatory
     Authority having jurisdiction over the sale of the Products.

    LICENSE PAYMENTS TO THIRD PARTIES

7.17 Any License or other rights acquired by Polymer for any Product under the
     provisions of this Agreement shall be subject to the terms of any
     applicable existing licenses granted to BLI with respect to any Products
     under any of the other agreements to which BLI may be a party.  BLI agrees
     to assign, sublicense or cause to be assigned or sublicensed to Polymer
     the rights and obligations under such agreements.

8.  MANUFACTURE OF PRODUCTS
 
    PRODUCTION

8.1  During any period of time in which:


     (a)  BLI has the exclusive right to Manufacture any Product,
          and

     (b)  Polymer has the right to Market or authorize another to
          Market that Product in any country in the Territory; and

     (c)  subject to the provisions of paragraphs 7.14 and 9.20
          of this Agreement,

     BLI shall produce and supply to Polymer and Polymer shall acquire from
     BLI, Polymer's entire requirements for that Product, in accordance
     with the terms of this Agreement.



8.2  Polymer shall, at the request of BLI enter into a Supply agreement with
     BLI for the Product in question on



<PAGE>   27

                                      -27-


     terms consistent with those in this Agreement and containing
     other terms and conditions commonly found in such agreements, to
     be negotiated in good faith between BLI and Polymer.

8.3  Upon execution of this Agreement and thereafter at the beginning of each
     calendar quarter Polymer shall provide BLI with a forecast showing the
     amount of the Product, by dosage strength, and expressed both in local
     currency and in units, that Polymer expects to order from BLI in the
     subsequent twelve (12) month period.

8.4  Provided that Polymer has delivered forecasts as required by paragraph
     8.3, and subject to the provisions of paragraph 8.5, BLI shall ensure that
     it has manufacturing capabilities sufficient to permit BLI to meet
     Polymers orders for the Product, provided there is not more than a twenty
     (20) percent divergence between Polymer's forecasts and the actual orders
     for the Product.  Provided BLI has used its reasonable best efforts to
     meet the requirements of Polymer as reflected in those forecasts, BLI
     shall have no liability to Polymer for any failure or inability to supply
     Polymer with quantities of Product in excess of the estimated requirements
     of Polymer as set out in such forecasts.

8.5  BLI shall notify Polymer if BLI determines that it will be unable to meet
     the estimated requirements of Polymer, as soon as practicable but in any
     event within fifteen (15) days after receiving such estimates.

   PURCHASE ORDERS

8.6  During the Term of this Agreement, Polymer shall submit to BLI, at least
     one hundred and twenty (120) days prior to the required date of delivery,
     purchase orders for Polymer's requirements of the Product, identifying the
     quantities of Product required by strength.  Each purchase order shall
     specify a delivery date which shall be not less than one hundred and
     twenty (120) days following the date of receipt by BLI of such order.  All
     purchase orders placed by Polymer hereunder shall be firm, in a form
     approved by BLI, and shall be sent by facsimile or by courier to such 
     address(es) as BLI may notify Polymer in writing.


<PAGE>   28

                                      -28-


8.7  BLI shall confirm acceptance of all purchase orders delivered in
     accordance with the provisions of paragraph 8.6, in writing or by
     facsimile, within two (2) weeks of BLI's receipt thereof, unless BLI has
     notified Polymer pursuant to paragraph 8.5 that BLI will be unable to fill
     all or part of any such purchase order.

8.8  BLI shall fill Polymer's accepted orders in accordance with the delivery
     dates specified in Polymer's purchase orders unless BLI has notified
     Polymer pursuant to paragraph 8.5 that BLI will be unable to fill all or
     part of any such purchase order.

   MANUFACTURING PRICE AND ROYALTY

8.9  Polymer shall pay to BLI for each dosage strength of each Product
     supplied to Polymer by BLI a price that is equivalent to one hundred and
     twenty-five percent (125%) of BLI's fully absorbed standard cost of that
     Product, as determined by generally accepted accounting principles as used
     and applied in Canada.

   PRODUCT QUALITY

8.10 BLI shall ensure that the Product is Manufactured in accordance with
     applicable GMP standards and with the applicable FDA regulations.

8.11 BLI shall perform all quality control tests and other inspections
     required by applicable GMP standards and FDA regulations.

8.12 BLI shall furnish to Polymer, for each lot of Product delivered to
     Polymer, a certificate that such lot meets the quality control standards
     set forth in the approved Application for Regulatory Approval, and a
     certificate of analysis for each lot.

8.13 Polymer shall notify BLI, within thirty (30) days of its actual receipt
     of each shipment of the Product, of any non-compliance of the Product with
     the requirements of paragraph 8.10.  If no notice of non-compliance is
     delivered to BLI within such thirty (30) day period, the Product so 
     delivered shall be deemed to comply with the provisions of paragraph 8.10.


<PAGE>   29
      
                                       -29-


8.14 The provisions of paragraph 8.13 do not apply to any deficiencies in the
     Product not reasonably detectable within thirty (30) days of actual
     receipt of the Product by Polymer.  Polymer shall notify BLI of any such
     deficiencies within forty-five (45) days after they come to the attention
     of Polymer.  BLI shall have no liability to Polymer with respect to any
     deficiencies of which BLI is not notified within such forty-five (45) day
     period.

8.15 Each of BLI and Polymer shall:

     (a)  allow the other, on request, such request to be
          provided ten (10) working days in advance, to inspect/audit its
          facilities and records pertaining to the testing, storage and
          Packaging of the Product to be sold by Polymer in the Territory
          for compliance with applicable GMP and FDA standards and
          regulations, provided such inspection or audit does not
          unreasonably interfere with its business operations; and

     (b)  supply to the other all data and results relating to
          all testing performed on the Product to be sold by Polymer in the
          Territory.

8.16 BLI shall replace, at its own expense, and without any undue delay, any
     Product that does not comply with the applicable GMP and FDA standards and
     regulations.

8.17 If, following the timely delivery of a notice by Polymer pursuant to the
     provisions of paragraph 8.13 hereof, Polymer and BLI do not agree that any
     lot or lots of the Product referred to in the notice meets all the
     requirements of paragraph 8.10 of this Agreement, that lot or those lots
     of the Product shall be tested for such compliance, within thirty (30)
     days after notice of the defect is delivered to BLI, by a reputable
     independent pharmaceutical testing laboratory selected by mutual agreement
     of BLI and Polymer.  If BLI and Polymer are unable to agree on the
     selection of that laboratory, the disagreement shall be resolved by
     arbitration.  The decision of such third party with respect to the
     question of compliance shall be binding upon BLI and Polymer for the
     purposes of paragraph 8.10 of this Agreement only.  The costs of that 
     testing shall be borne by the losing Party.

                                      -30-


   MANUFACTURING OPTION

8.18 Notwithstanding any other provisions of this Article 8, and upon the
     expiry of the exclusive right of BLI under paragraph 7.14, Polymer may
     manufacture, or obtain all but not less than all of its manufacturing
     requirements of any Product Licensed to Polymer in the Territory from
     another Person on terms which are more advantageous to Polymer than the
     terms upon which BLI is willing to provide such manufacturing, as provided
     for herein, subject to the terms and conditions of paragraphs 8.19 and
     8.21.

8.19 At least 30 days before entering into any agreement with any other Person
     providing for the Manufacture of the Product for Polymer by that other
     Person, Polymer shall provide notice in writing to BLI of the terms of the
     proposed agreement.  That notice shall include an offer by Polymer to
     purchase the Product from BLI on substantially the same terms and
     conditions as have been offered by such other Person. BLI shall have the
     right to accept or reject that offer in its sole discretion.

8.20 If BLI rejects or fails to accept such offer within 30 days of the date
     of delivery of that notice, Polymer shall have the right (subject to the
     provisions of paragraph 8.21) to enter into a Manufacturing Agreement with
     such other Person or any other Person on terms and conditions which are in
     the aggregate no more favorable to the proposed manufacturer than those
     contained in the offer described in paragraph 8.19.  Polymer shall at no
     time during the Term of this Agreement enter into any Manufacturing
     Agreement on terms more favourable to the proposed manufacturer than have
     been offered to BLI, which offer shall again be subject to the provisions
     of this paragraph 8.20.

8.21 The identity of any third-party manufacturer shall be subject to BLI's
     reasonable approval as to such Person's capability to manufacture the
     Products, which approval may be withheld only if any such manufacturer has
     insufficient manufacturing capabilities to manufacture the Products in
     accordance with the requirements of this Agreement (including lack 
     of compliance with GMP), or if such manufacturer's activities will have a


<PAGE>   31

                                      -31-


     material adverse effect on BLI's overall competitive position in
     the pharmaceutical industry.

8.22 If BLI refuses to approve a proposed manufacturer for any one or more of
     the Products, BLI shall supply that Product to Polymer, in accordance with
     the terms of this Agreement, for a price that is equivalent to the greater
     of:

     (a)  prevailing market rates, or

     (b)  one hundred and fifteen per cent (115%) of BLI's fully
          absorbed cost of that Product, as determined by generally
          accepted accounting principles as used and applied in Canada.

   RELEASE

8.23 BLI shall be released from the supply obligation and Polymer from the
     purchasing obligation as set forth in paragraph 8.1, in the following
     circumstances, and to the extent required by those circumstances:

     (a)  If the term of any agreement in respect of such supply
          of Products shall expire in accordance with its terms and
          provisions.

     (b)  If the Product delivered by BLI shall have repeatedly
          failed to comply with the quality control specifications
          established therefor and BLI fails satisfactorily to remedy such
          failure after written notice to such effect from Polymer.  Any
          disagreement regarding Biovail's compliance with the quality
          control specifications or with any Product meeting agreed
          standards shall be resolved by an independent laboratory selected
          by the parties hereto, or by arbitration.

     (c)  If any Regulatory Authority or other government
          authority in any country in the Territory shall have prevented
          the importation of the Product manufactured by BLI or any active
          or inactive component of such Product and BLI determines not to
          produce such Product in that country or at a place acceptable to  
          that Regulatory Authority or government authority.

                                      -32-


   POLYMER LICENSE ON RELEASE OF BLI

8.24 If any of the circumstances set forth in paragraph 8.23 occur and
     continue to exist:

     (a)  BLI shall promptly grant to Polymer a license to use
          the Biovail Technology and the data and information developed
          under this Agreement to Manufacture, have Manufactured, and to
          Market the Product in question in the Territory to the extent
          necessary to enable Polymer to do so without infringing any of
          BLI's Patent Rights and/or Know-How.  Any such license shall
          apply only to the specified Product and country, if applicable,
          and to the directly related use of the Biovail Technology to
          Manufacture that Product.

     (b)  To the extent that BLI may legally do so, having regard
          to BLI's existing contractual and legal obligations, BLI shall
          provide to Polymer the technical data necessary to enable Polymer
          to manufacture any such Product.  BLI shall deliver to Polymer
          any documentation necessary to manufacture the Product, including
          practical performance advice, shop practice, specifications as to
          materials to be used and control methods, and shall authorize
          reference to any relevant Biovail drug master files relating to
          the Product.

     (c)  BLI shall assist Polymer in the preparation of the
          systems, equipment and documentation necessary to manufacture the
          Product and in the training of Polymer's personnel necessary for
          such manufacturing.  BLI shall permit Polymer's scientific staff
          to visit BLI's manufacturing premises for certain specified
          periods, the terms of which shall be mutually agreed to by BLI
          and Polymer.

   SUPPLY TO LICENSEES OF POLYMER

8.25 The rights and obligations of BLI and Polymer under paragraphs 8.1 to
     8.24 shall apply, mutatis mutandis, to any Licensee of Polymer.


<PAGE>   33

                                      -33-


   STANDARD PRICING

8.26 Each of Polymer and BLI shall apply a policy in establishing a net
     selling price for each of the Products consistent with policies it applies
     in the case of similar transactions entered into with third party sources,
     or if there are no such sources, then on a basis which is commercially
     reasonable.

9. BIOVAIL OPTION

   BIOVAIL OPTION

9.1  With respect to any one Product which it so designates, BLI shall have
     the right, in its sole discretion, to exercise the Biovail Option, which
     is granted to BLI in consideration of the development work undertaken and
     to be undertaken hereunder in relation to the Products, all as provided
     for herein.  BLI shall exercise such right by providing written notice
     thereof to Polymer at any time up to sixty (60) days after Regulatory
     Approval of that Product in the U.S.A.

   PAYMENTS

9.2  In the event that BLI exercises the Biovail Option, BLI shall pay to
     Polymer, at the Option of BLI, either:

     (a)  A one-time cash fee of $25 million, within 30 days of
          the date of exercise of the Biovail Option, or

     (b)  Base royalties equal to 10% of Net Sales of the Product
          during the License Period on the same basis as the royalties
          payable by BLI under paragraph 7.5.

9.3  In the event that BLI exercises the Biovail Option, BLI shall re-acquire
     all rights relating to that Product, including, without limitation, the
     exclusive right to Manufacture and Market the Product in the Territory and
     in Canada.  Any license granted to Polymer in respect of that Product
     shall be terminated.

10. CONFIDENTIALITY; ACCESS TO INFORMATION

    OBLIGATIONS OF CONFIDENTIALITY

10.1 During the term of this Agreement and for a period of five years
     following its termination, Polymer shall maintain in confidence and shall
     not disclose to any other person, except as permitted by this Agreement,
     any of the Biovail Technology, and shall use such Biovail Technology only
     to perform its continuing obligations under this Agreement or following
     its termination, unless or except to the extent that the Biovail
     Technology:

          Polymer, such technology becomes known to the public other than
          by an unauthorized act or omission of Polymer or of their
          respective employees or agents (in which case the provisions
          above shall not apply to either party unless it can be
          established that such party or its agents disclosed such
          information in an act or omission).

    EXCEPTIONS

10.2 Nothing contained in paragraph 10.1 shall prevent Polymer, or BLI or BCI
     acting on behalf of Polymer, from disclosing any Biovail Technology to the
     extent that such Biovail Technology is required to be disclosed:

     (a)  in connection with the securing of necessary

     (e)  as may be required by applicable laws, regulations, or
          judicial determinations.

    SURVIVAL

10.3 The obligations of the parties pursuant to this Section 10 shall survive
     the termination of this Agreement for any reason.

11. PATENTS

    PATENT PROTECTION

11.1 BLI may apply for any Patent Rights in its own name and at its own
     expense, for any discoveries, inventions, improvements and innovations
     relating to the Products, whether made in fulfilling the obligations of
     BLI under this Agreement or otherwise.

    PATENT FILLINGS

11.2 Without limiting the provisions of paragraph 1 1.1 hereof, BLI shall
     cause appropriate applications for Patent Rights, and for any inventions
     relating to any Products developed hereunder which BLI reasonably believes
     to be patentable and technically significant, to be prepared and
     prosecuted in the United States of America and in any other countries in
     the Territory selected by Biovail in which patent protection appears to be
     available and effective, as Polymer and BLI shall reasonably agree from 
     time to time, and shall cause such Patent Rights to be maintained.  
     All of the costs


<PAGE>   36

                                      -36-


     of preparing, filing, prosecuting and maintaining such
     applications and patents, including the Patent Rights, shall be
     treated as Development Costs.

   INFRINGEMENT

11.3 In the event any party hereto is made aware of any alleged infringement
     of any Patent Rights, it shall promptly notify the other party of such
     infringement and the parties shall mutually agree upon an appropriate
     strategy to pursue the alleged infringer.  If one of the parties declines
     to join any infringement action, that party nevertheless shall join the
     other party if necessary as a plaintiff but shall be held free, clear and
     harmless from any and all costs and expenses of any litigation by the
     other party, who shall thereafter be solely entitled to retain any sums
     recovered in such suit or in settlement thereof.

   INFRINGEMENT PROCEDURES

11.4 In the event either party is charged by a third party with infringement
     of a patent or patents in relation to the commercialization of a Product,
     such party shall promptly notify the other party and the parties together
     shall mutually agree upon a defense strategy.

11.5 If the alleged infringement arises from the use or sale of a Product, the
     selling party shall hold the other party free, clear and harmless from any
     and all costs, expenses and damages arising from such litigation.

11.6 If the alleged infringement arises from the manufacturing process used
     for a Product:

     (a)  if BLI manufactures the product for Polymer hereunder,
          BLI shall hold Polymer free, clear and harmless from any and all
          costs, expenses (including attorneys' fees and disbursements) and
          damages arising from such litigation; and

     (b)  if Polymer has obtained such manufacturing from any
          other Person, Polymer shall hold BLI free, clear and harmless
          from any and all costs, expenses (including attorneys' fees and 
          disbursements) and damages arising from such litigation.

<PAGE>   37

                                      -37-


11.7 If the circumstances in paragraphs 11.5 and 11.6(a) above both apply to
     the infringement alleged by a third party, BLI and Polymer shall share
     equally all costs, expenses and damages arising from such litigation.

12. TERM AND TERMINATION

12.1 This Agreement shall remain in effect for the life of any relevant
     License or other payment or development obligation hereunder, whichever is
     longer or until such other time as Polymer and BLI may mutually determine.
     Thereafter, it shall continue automatically for additional periods of one
     year each upon terms to be mutually agreed upon by the parties hereto,
     unless terminated by Polymer or BLI upon 12 months' written notice.

12.2 The parties' respective obligations under Article 2 hereunder will
     terminate upon the expenditure by Polymer of all Available Funds, unless
     mutually agreed to by the parties hereto.

12.3 Notwithstanding the foregoing provisions of this Article 12, in the event
     that the offering contemplated by the Prospectus is not consummated and is
     withdrawn, this Agreement shall terminate and be of no further force and
     effect.

13. DEFAULT

    BREACH INCAPABLE OF REMEDY

13.1 In the event that there is a breath which is incapable of remedy of any
     of the terms or provisions hereof by one party, the other party shall have
     the right to terminate this Agreement on 30 days' notice by written notice
     to the party which shall be in breach.  For the purposes of this
     Agreement, a breach incapable of remedy shall be present:
