To the Holders of Common Stock of Fuisz Technologies Ltd.:

                                  INTRODUCTION

THE OFFER

    ABCI Acquisition Sub. Corporation, a Delaware company (the "Purchaser") and
a wholly-owned subsidiary of Biovail Corporation International, an Ontario,
Canada corporation ("Parent"), hereby offers to purchase up to 6,585,225 of the
outstanding shares (collectively, the "Shares") of common stock, par value $.01
per share (the "Company Common Stock"), of Fuisz Technologies Ltd., a Delaware
corporation (the "Company"), at a purchase price of $7.00 per Share, net to the
seller in cash, without interest thereon (the "Offer Price"), upon the terms and
subject to the conditions set forth in this Offer to Purchase and in the related
Letter of Transmittal (which, as amended or supplemented from time to time,
together constitute the "Offer"). The Company has informed the Purchaser that
there were 22,030,723 Shares of Company Common Stock outstanding as of July 25,
1999. The Purchaser and its affiliates beneficially own 4,209,829 of such
Shares. If 6,585,225 Shares are purchased pursuant to the Offer, Parent will
beneficially own approximately 49% of the outstanding Company Common Stock.

    THE OFFER IS CONDITIONED UPON, AMONG OTHER THINGS, THE SATISFACTION OR
WAIVER OF CERTAIN CONDITIONS, INCLUDING (I) THERE BEING VALIDLY TENDERED AND NOT
WITHDRAWN PRIOR TO THE EXPIRATION DATE SUCH NUMBER OF SHARES THAT WOULD SATISFY
THE MINIMUM CONDITION AND (II) THE EXPIRATION OF ANY WAITING PERIOD UNDER THE
ANTITRUST LAWS (AS DEFINED IN "THE TENDER OFFER--14. CERTAIN CONDITIONS OF THE
OFFER") APPLICABLE TO THE PURCHASE OF SHARES PURSUANT TO THE OFFER AND THE
MERGER (THE "ANTITRUST CONDITION"). THE OFFER IS SUBJECT TO OTHER TERMS AND
CONDITIONS AS DESCRIBED IN "THE TENDER OFFER--14. CERTAIN CONDITIONS OF THE
OFFER." THE PURCHASER RESERVES THE RIGHT, SUBJECT ONLY TO THE APPLICABLE RULES
AND REGULATIONS OF THE SECURITIES AND EXCHANGE COMMISSION (THE "COMMISSION"), TO
WAIVE EACH OF THE CONDITIONS (OTHER THAN THE MINIMUM CONDITION) TO THE
OBLIGATIONS OF THE PURCHASER TO CONSUMMATE THE OFFER TO THE EXTENT PERMITTED BY
LAW.

    The Offer is being made pursuant to an Agreement and Plan of Merger, dated
as of July 25, 1999 (the "Merger Agreement"), by and among Parent, the Purchaser
and the Company. The Merger Agreement provides, among other things, for the
commencement of the Offer by the Purchaser and further provides that, after the
purchase of Shares pursuant to the Offer and subject to the satisfaction or
waiver of certain conditions set forth therein, the Purchaser will be merged
with and into Company (the "Merger"), with the Company surviving the Merger as a
wholly-owned subsidiary of Parent. The surviving corporation of the Merger is
referred to herein as the "Surviving Corporation."

    In the Merger, each Share issued and outstanding immediately prior to the
effective time of the Merger (other than shares held by Parent, the Purchaser,
any direct or indirect wholly-owned subsidiary of Parent, in the treasury of the
Company or by any direct or indirect wholly-owned subsidiary of the Company)
will be converted into the right to receive a fraction of a common share, no par
value, of Parent (the "Parent Common Stock") based on an exchange ratio
determined as follows: (i) if the average of the daily closing prices per share
of Parent Common Stock on the New York Stock Exchange ("NYSE") Composite
Transactions Reporting System, as reported in The Wall Street Journal for the
fifteen trading days ending on the date immediately prior to the second full
NYSE trading day immediately preceding the Closing Date ("the Average Trading
Price"); is less than $45.00, the Exchange Ratio shall equal .1556; (ii) if the
Average Trading Price is greater than or equal to $45.00, but less than or equal
to $58.625, the Exchange Ratio shall equal a fraction (rounded to the nearest
ten-thousandth) determined by dividing $7.00 by the Average Trading Price; (iii)
if the Average Trading Price is greater than $58.625 but less than or equal to
$62.810, the Exchange Ratio shall equal .1194 and (iv) if the Average Trading
Price is greater than $62.810, the Exchange Ratio shall equal a fraction
(rounded to the nearest ten-thousandth) determined by dividing $7.50 by the
Average Trading Price subject to adjustment as provided in the Merger Agreement
(the "Merger Consideration" and, together with the Offer Price, the
"Consideration"). On July 23, 1999, the last full day of trading prior to the
announcement of the execution of the Merger Agreement, the reported last sale
price of the Parent Common Stock on the NYSE was $58 5/8 per share of Parent
Common Stock. Shareholders are urged to obtain a current market quotation for
the Parent
<PAGE>
Common Stock. The consummation of the Merger is subject to the satisfaction or
waiver of certain conditions, including (i) the Minimum Condition and (ii) the
Antitrust Condition See "THE TENDER OFFER--12. Purpose of the Offer and the
Merger; Plans for the Company; the Merger Agreement."

    THE BOARD OF DIRECTORS OF THE COMPANY HAS APPROVED THE OFFER, THE MERGER AND
THE MERGER AGREEMENT AND DETERMINED THAT THE TERMS OF EACH OF THE OFFER AND THE
MERGER ARE FAIR TO AND IN THE BEST INTERESTS OF THE COMPANY'S SHAREHOLDERS, AND
RECOMMENDS THAT THE COMPANY'S SHAREHOLDERS ACCEPT THE OFFER AND TENDER ALL OF
THEIR SHARES PURSUANT TO THE OFFER.

                                THE TENDER OFFER

1.  TERMS OF THE OFFER; PRORATION; EXPIRATION DATE

    Upon the terms and subject to the conditions of the Offer (including, if the
Offer is extended or amended, the terms and conditions of any extension or
amendment), the Purchaser will accept for payment and pay for up to 6,585,225 of
the outstanding Shares of Company Common Stock (the "Maximum Number of Shares")
validly tendered prior to the Expiration Date and not withdrawn in accordance
with "THE TENDER OFFER--4. Withdrawal Rights." The Offer is conditioned upon,
among other things, there being validly tendered and not withdrawn prior to the
Expiration Date at least 4,602,460 Shares (the "Minimum Condition"). The term
"Expiration Date" means 12:00 midnight, New York City time, on August 26, 1999,
unless and until the Purchaser, in accordance with the terms of the Merger
Agreement, shall have extended the period of time during which the Offer is
open, in which event the term "Expiration Date" shall mean the latest time and
date at which the Offer, as so extended by the Purchaser, shall expire.

    If more than the Maximum Number of Shares are validly tendered prior to the
Expiration Date and not properly withdrawn, the Purchaser will, upon the terms
and subject to the conditions of the Offer, accept for payment and pay for only
the Maximum Number of Shares on a pro rata basis, with adjustments to avoid
purchases of fractional Shares, based upon the number of Shares validly tendered
prior to the Expiration Date and not properly withdrawn.

    In the event that proration of tendered Shares is required, because of the
difficulty of determining precisely the number of Shares validly tendered and
not withdrawn (due in part to the guaranteed delivery procedure described in
"THE TENDER OFFER--3. Procedures for Tendering Shares"), the Purchaser does not
expect to be able to announce the final results of such proration or pay for any
Shares until at least five Nasdaq National Market ("NASDAQ") trading days after
the Expiration Date. Preliminary results of proration will be announced by press
release as promptly as practicable after the Expiration Date. Shareholders may
obtain such information from the Information Agent and may also be able to
obtain such information from their brokers.

    Consummation of the Offer is conditioned upon, among other things,
satisfaction of each of the Minimum Condition and the Antitrust Condition. The
Offer also is subject to certain other conditions set forth in "THE TENDER
OFFER--14. Certain Conditions of the Offer" (together with the Minimum Condition
and the Antitrust Condition, the "Offer Conditions").

    Pursuant to the terms of the Merger Agreement, Parent and the Purchaser
expressly reserve the right (but are not obligated) to waive any or all of the
Offer Conditions to the extent permitted by law. If any of the Offer Conditions
are not satisfied prior to the Expiration Date, Parent and the Purchaser reserve
the right (but are not obligated) to (i) decline to purchase any or all of the
Shares tendered and terminate the Offer, and return all such tendered Shares to
tendering shareholders, (ii) waive any or all Offer Conditions and, subject to
complying with applicable rules and regulations of the Commission, purchase all
Shares validly tendered and not theretofore withdrawn, (iii) subject to the
terms of the Merger Agreement, extend the Offer and, subject to the right of
shareholders to withdraw Shares until the Expiration Date, retain the Shares
which have been tendered during the period or periods for which the Offer is
extended or (iv) subject to the terms of the Merger Agreement, otherwise amend
the Offer. In addition, Parent has agreed in the Merger Agreement that it will
not, without the consent of the Company, (i) decrease the Offer Price, (ii)
waive the Minimum Condition, (iii) change the form of consideration payable in
the Offer, (iv) decrease the number of Shares sought to be purchased in the
Offer, (v) change the conditions set forth in "THE TENDER OFFER--14. Certain
Conditions of the Offer," (vi) impose additional conditions to the Offer or
(vii) amend any other term of the Offer in a manner adverse to the Company's
shareholders.

    Subject to the terms of the Merger Agreement and the applicable rules and
regulations of the Commission, except as described below, the Purchaser
expressly reserves the right, in its sole discretion, at

                                       4
<PAGE>
any time and from time to time, and regardless of the occurrence of any of the
events specified in "THE TENDER OFFER--14. Certain Conditions of the Offer," by
giving oral or written notice to the Depositary, as described below, to (i)
extend the period of time during which the Offer is open, and thereby delay
acceptance of such payment of, and the payment for any Shares and (ii) amend the
Offer in any other respect. UNDER NO CIRCUMSTANCES WILL INTEREST BE PAID ON THE
OFFER PRICE OF THE SHARES TO BE PAID BY THE PURCHASER, REGARDLESS OF ANY
EXTENSION OF THE OFFER OR ANY DELAY IN MAKING SUCH PAYMENT. During any such
extension, all Shares previously tendered and not withdrawn will remain subject
to the Offer, subject to the rights of a tendering shareholder to withdraw any
tendered Shares. See "THE TENDER OFFER--4. Withdrawal Rights."

    There can be no assurance that Parent will exercise its right to extend the
Offer (other than as required by the Merger Agreement). In the Merger Agreement,
Parent has agreed to extend the Offer, from time to time to the extent any
conditions to the Offer reasonably capable of being satisfied have not been
satisfied on the applicable expiration date but not beyond the 55th business day
from and including the business day the Offer commences. Any such extension
shall not be for a period greater than the period of time Parent reasonably
expects to be necessary to satisfy such conditions.

    If the Purchaser extends the Offer or if the Purchaser (whether before or
after its acceptance for payment of Shares) is delayed in its acceptance for
payment of or payment for Shares or is unable to pay for Shares pursuant to the
Offer for any reason, then, without prejudice to the Purchaser's rights under
the Offer, the Depositary may retain tendered Shares on behalf of the Purchaser,
and such Shares may not be withdrawn except to the extent tendering shareholders
are entitled to withdrawal rights as described in "THE TENDER OFFER--4.
Withdrawal Rights." However, the ability of the Purchaser to delay the payment
for Shares that the Purchaser has accepted for payment is limited by Rule 14e-1
under the Exchange Act, which requires that a bidder pay the consideration
offered or return the securities deposited by or on behalf of holders of
securities promptly after the termination or withdrawal of the Offer.

    Any extension, amendment or termination of the Offer will be followed as
promptly as practicable by public announcement thereof, the announcement in the
case of an extension to be issued no later than 9:00 a.m., New York City Time,
on the next business day after the previously scheduled Expiration Date in
accordance with Rules 14d-4(c), 14d-6(d) and 14e-1(d) under the Exchange Act.
Without limiting the obligations of the Purchaser under such Rules or the manner
in which the Purchaser may choose to make any public announcement, the Purchaser
currently intends to make announcements by issuing a press release to the
Business Wire. As used in this Offer to Purchase, "business day" has the meaning
set forth in Rule 14d-1 under the Exchange Act. The minimum period during which
an offer must remain open following material changes in the terms of the Offer
or information concerning the Offer, other than a change in price or a change in
the percentage of securities sought, will depend upon the facts and
circumstances then existing, including the materiality of the changed terms or
information. With respect to a change in price or a change in the percentage of
securities sought, a minimum period of ten business days generally is required
to allow for adequate dissemination of information concerning the change to
shareholders.

    The Company has provided the Purchaser with the Company's shareholder list
and security position listings for the purpose of disseminating the Offer to
holders of the Shares. This Offer to Purchase, the related Letter of Transmittal
and other relevant materials will be mailed by the Purchaser to record holders
of Shares and will be furnished by the Purchaser to brokers, dealers, banks,
trust companies and similar persons whose names, or the names of whose nominees,
appear on the shareholder lists or, if applicable, who are listed as
participants in a clearing agency's security position listing, for subsequent
transmittal to beneficial owners of Shares.

2.  ACCEPTANCE FOR PAYMENT AND PAYMENT FOR SHARES

    Upon the terms and subject to the conditions of the Offer (including, if the
Offer is extended or amended, the terms and conditions of any such extension or
amendment), the Purchaser will purchase, by accepting for payment, and will pay
for, the Maximum Number of Shares validly tendered prior to the Expiration Date
(and not properly withdrawn in accordance with "THE TENDER OFFER--4. Withdrawal
Rights") promptly after the Expiration Date. Any determination concerning the
satisfaction of such terms and conditions shall be within the sole discretion of
the Purchaser. See "THE TENDER OFFER--4. Withdrawal Rights." Subject to the
terms of the Merger Agreement, the Purchaser expressly reserves the right, in
its sole discretion, to delay acceptance for payment of, or, subject to the
applicable rules of the Commission, payment for, Shares in order to comply in
whole or in part with any applicable law. See "THE TENDER OFFER--15. Certain
Legal Matters; Regulatory Approvals." Any such delays will be effected in
compliance with Rule 14e-1(c) under the Exchange Act (relating to the
Purchaser's obligation to pay for or return tendered Shares promptly after the
termination or withdrawal of the Offer).

    In all cases, payment for Shares tendered and accepted for payment pursuant
to the Offer will be made only after timely receipt by the Depositary of (i) the
certificate(s) representing tendered Shares (the "Share Certificates") or timely
confirmation of a book-entry transfer (a "Book-Entry Confirmation") of such
Shares (if such procedure is available) into the Depositary's account at The
Depository Trust Company (the "Book-Entry Transfer Facility") pursuant to the
procedures set forth in "THE TENDER
OFFER--3. Procedures for Tendering Shares," (ii) the Letter of Transmittal (or
facsimile thereof), properly completed and duly executed, or an Agent's Message
(as defined herein) in connection with a book-entry transfer, and (iii) any
other documents required by the Letter of Transmittal.

    The term "Agent's Message" means a message, transmitted by the Book-Entry
Transfer Facility to, and received by, the Depositary and forming a part of a
Book-Entry Confirmation, which states that the Book-Entry Transfer Facility has
received an express acknowledgment from the participant in the Book-Entry
Transfer Facility tendering the Shares that such participant has received and
agrees to be bound by the terms of the Letter of Transmittal and that the
Purchaser may enforce such agreement against the participant.

    For purposes of the Offer, the Purchaser will be deemed to have accepted for
payment, and thereby purchased, tendered Shares if, as and when the Purchaser
gives oral or written notice to the Depositary of the Purchaser's acceptance of
such Shares for payment. Payment for Shares accepted pursuant to the Offer will
be made by deposit of the aggregate purchase price therefor with the Depositary,
which will act as agent for tendering shareholders for the purpose of receiving
payment from the Purchaser and transmitting payment to such tendering
shareholders. UNDER NO CIRCUMSTANCES WILL INTEREST ON THE OFFER PRICE FOR SHARES
BE PAID BY THE PURCHASER BY REASON OF ANY DELAY IN MAKING SUCH PAYMENT.

    In the Merger Agreement, Parent has agreed that, following the satisfaction
or waiver of all of the conditions to the Offer, the Purchaser shall accept for
payment, in accordance with the terms of the Offer, the Maximum Number of Shares
which are validly tendered and not withdrawn as soon as practicable thereafter,
except as otherwise consented to by the Company. If, for any reason whatsoever,
acceptance for payment of or payment for any Shares tendered pursuant to the
Offer is delayed, or the Purchaser is unable to accept for payment or pay for
Shares tendered pursuant to the Offer, then, without prejudice to the
Purchaser's rights set forth herein, the Depositary may, nevertheless, on behalf
of the Purchaser and subject to Rule 14e-1(c) under the Exchange Act, retain
tendered Shares and such Shares may not be withdrawn except to the extent that
the tendering shareholder is entitled to and duly exercises withdrawal rights as
described in "THE TENDER OFFER--4. Withdrawal Rights."

    If more than 6,585,225 Shares are validly tendered prior to the Expiration
Date and not withdrawn, Purchaser will, upon the terms and subject to the
conditions of the Offer, accept such Shares for payment

                                       6
<PAGE>
on a PRO RATA basis, with adjustments to avoid purchases of fractional Shares,
based upon the number of Shares validly tendered prior to the Expiration Date
and not withdrawn.

    Because of the difficulty of determining precisely the number of Shares
validly tendered and not withdrawn, if proration is required, Purchaser would
not expect to announce the final results of proration until approximately seven
NASDAQ trading days after the Expiration Date. Preliminary results of proration
will be announced by press release as promptly as practicable after the
Expiration Date. Holders of Shares may obtain such preliminary information from
the Depositary, and may also be able to obtain such preliminary information from
their brokers. Purchaser will not pay for any Shares accepted for payment
pursuant to the Offer until the final proration factor is known.

    If any tendered Shares are not accepted for payment for any reason pursuant
to the terms and conditions of the Offer (including due to proration if more
than the Maximum Number of Shares of the Company are tendered) or if Share
Certificates are submitted evidencing more Shares than are tendered, Share
Certificates evidencing unpurchased or untendered Shares will be returned,
without expense to the tendering shareholder (or, in the case of Shares tendered
by book-entry transfer into the Depositary's account at the Book-Entry Transfer
Facility pursuant to the procedure set forth in "THE TENDER OFFER--3. Procedures
for Tendering Shares," such Shares will be credited to an account maintained at
the Book-Entry Transfer Facility), as promptly as practicable following the
expiration or termination of the Offer.

    If, prior to the Expiration Date, the Purchaser increases the consideration
offered to shareholders pursuant to the Offer, such increased consideration will
be paid to all shareholders whose Shares are purchased pursuant to the Offer,
regardless of whether those Shares were tendered prior to or after the increase
in consideration.

    Subject to the provisions of the Merger Agreement, Parent may assign its
rights and obligations under the Merger Agreement or those of Acquisition Sub to
Parent or any subsidiary of Parent, but in each case no such assignment shall
relieve Parent or Acquisition Sub, of its obligations under the Merger
Agreement.

    Parent and the Company each will file a Notification and Report Form with
respect to the transactions contemplated by the Merger Agreement under the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the "HSR
Act"). The waiting period under the HSR Act will expire at 11:59 p.m., New York
City Time, on the 30th calendar day after filing of the HSR forms by Parent and
the Company, unless the Antitrust Division of the United States Department of
Justice (the "Antitrust Division") or the United States Federal Trade Commission
(the "FTC") extends the waiting period by requesting additional information or
documentary material from Parent and the Company. If such a request is made,
such waiting period will expire at 11:59 p.m., New York City Time, on the 20th
day after substantial compliance by Parent and the Company with such request.
See "THE TENDER OFFER--15. Certain Legal Matters; Regulatory Approvals" for
additional information concerning the HSR Act and the applicability of the
antitrust laws to the Offer.

3.  PROCEDURES FOR TENDERING SHARES

    VALID TENDER OF SHARES.  Except as set forth below, in order for Shares to
be validly tendered pursuant to the Offer, the Letter of Transmittal or a
facsimile thereof, properly completed and duly executed, with any required
signature guarantees, or an Agent's Message in connection with a book-entry
delivery of Shares and any other required documents, must be received by the
Depositary at one of its addresses set forth on the back cover of this Offer to
Purchase prior to the Expiration Date and either (i) the Share Certificates
evidencing tendered Shares must be received by the Depositary along with the
Letter of Transmittal, (ii) Shares must be tendered pursuant to the procedure
for book-entry transfer described below and a Book-Entry Confirmation must be
received by the Depositary, in each case, prior to the Expiration Date, or (iii)
the tendering shareholder must comply with the guaranteed delivery procedures
described below.

                                       7
<PAGE>
    If Share Certificates are forwarded to the Depositary in multiple
deliveries, a properly completed and duly executed Letter of Transmittal (or a
facsimile thereof) must accompany each delivery. No alternative, conditional or
contingent tenders will be accepted and no fractional Shares will be purchased.

    THE METHOD OF DELIVERY OF SHARE CERTIFICATES, THE LETTER OF TRANSMITTAL AND
ALL OTHER REQUIRED DOCUMENTS, INCLUDING DELIVERY THROUGH THE BOOK-ENTRY TRANSFER
FACILITY, IS AT THE OPTION AND RISK OF THE TENDERING SHAREHOLDER. SHARES WILL BE
DEEMED DELIVERED ONLY WHEN ACTUALLY RECEIVED BY THE DEPOSITARY (INCLUDING, IN
THE CASE OF A BOOK-ENTRY TRANSFER, BY BOOK-ENTRY CONFIRMATION). IF DELIVERY IS
BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED, PROPERLY INSURED, IS
RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ENSURE TIMELY
DELIVERY.

    BOOK-ENTRY TRANSFER.  The Depositary will establish an account at the
Book-Entry Transfer Facility with respect to the Shares for purposes of the
Offer within two business days after the date of this Offer to Purchase, and any
financial institution that is a participant in the Book-Entry Transfer
Facility's system may make book-entry delivery of Shares by causing the
Book-Entry Transfer Facility to transfer such Shares into the Depositary's
account at the Book-Entry Transfer Facility in accordance with the Book-Entry
Transfer Facility's procedures for transfer. Although delivery of Shares may be
effected through book-entry transfer at the Book-Entry Transfer Facility, the
Letter of Transmittal or a facsimile thereof, with any required signature
guarantees, or an Agent's Message in connection with a book-entry delivery of
Shares, and any other required documents, must, in any case, be transmitted to
and received by the Depositary at one of its addresses set forth on the back
cover of this Offer to Purchase prior to the Expiration Date or the guaranteed
delivery procedures described below must be complied with.

    REQUIRED DOCUMENTS MUST BE TRANSMITTED TO AND RECEIVED BY THE DEPOSITARY AT
ONE OF ITS ADDRESSES SET FORTH ON THE BACK COVER PAGE OF THIS OFFER TO PURCHASE.
DELIVERY OF DOCUMENTS TO THE BOOK-ENTRY TRANSFER FACILITY IN ACCORDANCE WITH THE
BOOK-ENTRY TRANSFER FACILITY'S PROCEDURES DOES NOT CONSTITUTE DELIVERY TO THE
DEPOSITARY.

    SIGNATURE GUARANTEES.  No signature guarantee is required on the Letter of
Transmittal if the Shares tendered thereby are tendered (i) by a registered
holder of Shares who has not completed either the box entitled "Special Delivery
Instructions" or the box entitled "Special Payment Instructions" on the Letter
of Transmittal or (ii) for the account of a bank, broker, dealer, credit union,
savings association or other entity that is a member in good standing of the
Securities Transfer Agents Medallion Program (each, an "Eligible Institution").
In all other cases, all signatures on the Letter of Transmittal must be
guaranteed by an Eligible Institution. See Instruction 1 of the Letter of
Transmittal.

    If a Share Certificate is registered in the name of a person other than the
signer of the Letter of Transmittal or if payment is to be made to a person
other than the registered holder(s), or if a Share Certificate not accepted for
payment is to be returned to a person other than the registered holder(s), or if
a portion of the Shares evidenced by such Share Certificate are to be returned
because fewer than all of the Shares evidenced by such Share Certificate are to
be tendered to a person other than the registered holder(s), then the Share
Certificate must be endorsed or accompanied by appropriate stock powers, in any
of these cases, signed exactly as the name(s) of the registered holder(s) appear
on the Share Certificate, with the signature(s) on such Share Certificate or
stock powers guaranteed as described above. See Instructions 1 and 5 of the
Letter of Transmittal.

    GUARANTEED DELIVERY.  If a shareholder desires to tender Shares pursuant to
the Offer and such shareholder's Share Certificates are not immediately
available or time will not permit all required documents to reach the Depositary
prior to the Expiration Date or the procedure for book-entry transfer

                                       8
<PAGE>
cannot be completed on a timely basis, such Shares may nevertheless be tendered
if all the following conditions are satisfied:

        (i) the tender is made by or through an Eligible Institution;

        (ii) a properly completed and duly executed Notice of Guaranteed
    Delivery, substantially in the form provided by the Purchaser herewith, is
    received by the Depositary as provided below prior to the Expiration Date;
    and

       (iii) the Share Certificates (or a Book-Entry Confirmation) representing
    all tendered Shares in proper form for transfer together with a properly
    completed and duly executed Letter of Transmittal (or facsimile thereof),
    with any required signature guarantees (or, in the case of a book-entry
    transfer, an Agent's Message) and any other documents required by the Letter
    of Transmittal are received by the Depositary within three NASDAQ trading
    days after the date of execution of such Notice of Guaranteed Delivery.

    Any Notice of Guaranteed Delivery may be delivered by hand or transmitted by
facsimile transmission or mailed to the Depositary, and must include a guarantee
by an Eligible Institution in the form set forth in the Notice of Guaranteed
Delivery.

    Notwithstanding any other provisions hereof, payment for Shares accepted for
payment pursuant to the Offer will in all cases be made only after timely
receipt by the Depositary of Share Certificates for, or of Book-Entry
Confirmation with respect to, such Shares, a properly completed and duly
executed Letter of Transmittal (or a facsimile thereof), together with any
required signature guarantees (or, in the case of a book-entry transfer, an
Agent's Message) and any other documents required by the Letter of Transmittal.
Accordingly, payment might not be made to all tendering shareholders at the same
time and will depend upon when Share Certificates are received by the Depositary
or Book-Entry Confirmations with respect to such Shares are received into the
Depositary's account at the Book-Entry Transfer Facility.

    The valid tender of Shares pursuant to one of the procedures described above
will constitute a binding agreement between the tendering shareholder and the
Purchaser upon the terms and subject to the conditions of the Offer.

    APPOINTMENT AS PROXY.  Except as otherwise prohibited by Law, by executing a
Letter of Transmittal as set forth above, a tendering shareholder irrevocably
appoints certain designees of the Purchaser as such shareholder's
attorneys-in-fact and proxies, in the manner set forth in the Letter of
Transmittal, each with full power of substitution, to the full extent of such
shareholder's rights with respect to the Shares tendered by such shareholder and
accepted for payment by the Purchaser (and any and all non-cash dividends,
distributions, rights or other securities issued or issuable in respect of such
Shares on or after the date of the Offer). All such proxies shall be considered
coupled with an interest in the tendered Shares. This appointment will be
effective if, when and only to the extent that the Purchaser accepts such Shares
for payment pursuant to the Offer. Upon such acceptance for payment, all prior
proxies given by such shareholder with respect to such Shares and other
securities will, without further action, be revoked, and no subsequent proxies
may be given. The designees of the Purchaser will, with respect to the Shares
and other securities for which the appointment is effective, be empowered to
exercise all voting and other rights of such shareholder as they, in their sole
discretion, may deem proper at any annual, special, adjourned or postponed
meeting of the Company's shareholders, or otherwise, and the Purchaser reserves
the right to require that in order for Shares or other securities to be deemed
validly tendered, immediately upon the Purchaser's acceptance for payment of
such Shares, the Purchaser must be able to exercise full voting rights with
respect to such Shares.

    DETERMINATION OF VALIDITY.  All questions as to the validity, form,
eligibility (including time of receipt) and acceptance for payment of any
tendered Shares pursuant to any of the procedures described above will be
determined by the Purchaser, in its sole discretion, whose determination will be
final and binding on all parties. The Purchaser reserves the absolute right, in
its sole discretion, to reject any or all tenders of

                                       9
<PAGE>
Shares determined by it not to be in proper form or if the acceptance for
payment of, or payment for, such Shares may, in the opinion of the Purchaser's
counsel, be unlawful. The Purchaser also reserves the absolute right, in its
sole discretion, to waive any defect or irregularity in any tender with respect
to Shares of any particular shareholder, whether or not similar defects or
irregularities are waived in the case of other shareholders. No tender of Shares
will be deemed to have been validly made until all defects and irregularities
have been cured or waived.

    The Purchaser's interpretation of the terms and conditions of the Offer
(including the Letter of Transmittal and the instructions thereto) will be final
and binding. None of Parent, the Purchaser, the Dealer Manager, the Depositary,
the Information Agent or any other person will be under any duty to give
notification of any defects or irregularities in tenders or will incur any
liability for failure to give any such notification.

    BACKUP WITHHOLDING.  In order to avoid "backup withholding" of federal
income tax on payments of the Offer Price pursuant to the Offer, a shareholder
surrendering Shares in the Offer must, unless an exemption applies, provide the
Depositary with such shareholder's correct taxpayer identification number
("TIN") on a Substitute Form W-9 and certify under penalty of perjury that such
TIN is correct and that such shareholder is not subject to backup withholding.
Certain shareholders (including, among others, all corporations and certain
foreign individuals and entities) are not subject to backup withholding. If a
shareholder does not provide its correct TIN or fails to provide the
certifications described above, the Internal Revenue Service ("IRS") may impose
a penalty on such shareholder and payment of the Offer Price to such shareholder
pursuant to the Offer may be subject to backup withholding of 31% of the amount
payable to such shareholder. All shareholders surrendering Shares pursuant to
the Offer should complete and sign the main signature form and the Substitute
Form W-9 included as part of the Letter of Transmittal to provide the
information and certification necessary to avoid backup withholding (unless an
applicable exemption exists and is proven in a manner satisfactory to the
Purchaser and the Depositary). Noncorporate foreign shareholders should complete
and sign the main signature form and a Form W-8, Certificate of Foreign Status,
a copy of which may be obtained from the Depositary, in order to avoid backup
withholding. See Instruction 10 to the Letter of Transmittal.

    TENDERING SHAREHOLDER'S REPRESENTATION AND WARRANTY; PURCHASER'S ACCEPTANCE
CONSTITUTES AN AGREEMENT. A tender of Shares pursuant to any of the procedures
described above will constitute the tendering shareholder's acceptance of the
terms and conditions of the Offer, as well as the tendering shareholder's
representation and warranty to Parent, Purchaser and the Company that (a) such
shareholder has a net long position in the Shares being tendered within the
meaning of Rule 14e-4 promulgated by the Commission under the Exchange Act and
(b) the tender of such Shares complies with Rule 14e-4. It is a violation of
Rule 14e-4 for a person acting alone or in concert with others, directly or
indirectly, to tender Shares for such person's own account unless at the time of
tender and at the Expiration Date such person has a "net long position" equal to
or greater than the amount tendered in (i) Shares and will deliver or cause to
be delivered such Shares for the purpose of tender to the Purchaser within the
period specified in the Offer, or (ii) other securities immediately convertible
into, exercisable for or exchangeable into Shares ("Equivalent Securities") and,
upon the acceptance of such tender, will acquire such Shares by conversion,
exchange or exercise of such Equivalent Securities to the extent required by the
terms of the Offer and will deliver or cause to be delivered such Shares so
acquired for the purpose of tender to the Purchaser within the period specified
in the Offer. Rule 14e-4 provides a similar restriction applicable to the tender
or guarantee of a tender on behalf of another person. The Purchaser's acceptance
for payment of Shares tendered pursuant to the Offer will constitute a binding
agreement between the tendering shareholder and the Purchaser upon the terms and
conditions of the Offer.

    CERTIFICATES FOR SHARES, TOGETHER WITH A PROPERLY COMPLETED LETTER OF
TRANSMITTAL AND ANY OTHER DOCUMENTS REQUIRED BY THE LETTER OF TRANSMITTAL, MUST
BE DELIVERED TO THE DEPOSITARY AND NOT TO THE COMPANY OR THE DEALER MANAGERS.
ANY SUCH DOCUMENTS DELIVERED TO THE COMPANY

                                       10
<PAGE>
OR THE DEALER MANAGER WILL NOT BE FORWARDED TO THE DEPOSITARY AND THEREFORE WILL
NOT BE DEEMED TO BE VALIDLY TENDERED.

4.  WITHDRAWAL RIGHTS

    Except as otherwise provided in this Section 4, tenders of Shares made
pursuant to the Offer are irrevocable. Shares tendered pursuant to the Offer may
be withdrawn at any time prior to the Expiration Date and, unless previously
accepted for payment by the Purchaser pursuant to the Offer, may also be
withdrawn at any time after September 27, 1999.

    If the Purchaser extends the Offer, is delayed in its acceptance for payment
of Shares or is unable to accept Shares for payment pursuant to the Offer for
any reason, then, without prejudice to the Purchaser's rights under the Offer,
the Depositary may, nevertheless, on behalf of the Purchaser, retain tendered
Shares, and such Shares may not be withdrawn except to the extent that tendering
shareholders are entitled to withdrawal rights as described in this Section 4;
subject, however, to the Purchaser's obligation, pursuant to Rule 14e-1(c) under
the Exchange Act, to pay for the tendered Shares or return those Shares promptly
after termination or withdrawal of the Offer. Any such delay will be accompanied
by an extension of the Offer to the extent required by law.

    For a withdrawal to be effective, a written or facsimile transmission notice
of withdrawal must be timely received by the Depositary at one of its addresses
set forth on the back cover of this Offer to Purchase. Any such notice of
withdrawal must specify the name of the person who tendered the Shares to be
withdrawn, the number of Shares to be withdrawn and (if Share Certificates have
been tendered) the name of the registered holder, if different from that of the
person who tendered such Shares. If Share Certificates evidencing Shares to be
withdrawn have been delivered or otherwise identified to the Depositary, then
prior to the release of such Share Certificates, the serial numbers shown on the
particular Share Certificates to be withdrawn must be submitted to the
Depositary, and the signature(s) on the notice of withdrawal must be guaranteed
by an Eligible Institution, unless such Shares have been tendered for the
account of an Eligible Institution. If Shares have been tendered pursuant to the
procedure for book-entry transfer as set forth in "THE TENDER OFFER--3.
Procedures for Tendering Shares," any notice of withdrawal must also specify the
name and number of the account at the Book-Entry Transfer Facility to be
credited with the withdrawn Shares, in which case a notice of withdrawal will be
effective if delivered to the Depositary by any method of delivery described in
"THE TENDER OFFER--3. Procedures for Tendering Shares." Withdrawals of Shares
may not be rescinded.

    All questions as to the form and validity (including, without limitation,
time of receipt) of notices of withdrawal will be determined by the Purchaser,
in its sole discretion, the determination of which will be final and binding.
None of Parent, the Purchaser, the Dealer Manager, the Depositary, the
Information Agent or any other person will be under any duty to give
notification of any defects or irregularities in any notice of withdrawal or
incur any liability for failure to give any such notification.

    Any Shares properly withdrawn will thereafter be deemed to not have been
validly tendered for purposes of the Offer. Withdrawn Shares may be retendered
at any time prior to the Expiration Date by following one of the procedures
described in "THE TENDER OFFER--3. Procedures for Tendering Shares."

5.  CERTAIN UNITED STATES FEDERAL INCOME TAX CONSEQUENCES OF THE OFFER AND THE
    MERGER

    The following discussion is a summary of the material federal income tax
consequences of the Offer and the Merger to holders of Shares who hold the
Shares as capital assets. The discussion set forth below is for general
information only and may not apply to certain categories of holders of Shares
subject to special treatment under the Internal Revenue Code of 1986, as amended
(the "Code"), such as foreign holders and holders who acquired such Shares
pursuant to the exercise of employee stock options or otherwise as compensation.
This summary is based upon laws, regulations, rulings, and decisions currently
in effect, all of which are subject to change, retroactively or prospectively.

                                       11
<PAGE>
    A shareholder of the Company will recognize gain or loss with respect to
Shares exchanged pursuant to the Offer equal to the difference between the
amount of cash received and such shareholder's adjusted tax basis in the Shares
surrendered pursuant to the Offer, and will recognize gain or loss with respect
to Shares exchanged pursuant to the Merger equal to the difference between the
fair market value of the Parent Common Stock received and such shareholder's
adjusted tax basis in the Shares exchanged pursuant to the Merger.

CHARACTERIZATION OF GAIN OR LOSS

    The gain or loss recognized, if any, by a shareholder of the Company
pursuant to the Offer or the Merger will be capital gain or loss and if, as of
the date of the exchange pursuant to the Offer or the Merger, as the case may
be, the shareholder has held the Shares surrendered for more than one year, such
capital gain will be long-term. The amount of any gain or loss recognized and
its character as short-term or long-term will be calculated and determined
separately for each identifiable block of Shares surrendered pursuant to the
Offer and the Merger.

BACKUP WITHHOLDING

    Unless a shareholder complies with certain reporting and/or certification
procedures or is an exempt recipient under applicable provisions of the Code and
Treasury Regulations promulgated thereunder, such shareholder may be subject to
withholding tax of 31% with respect to any cash payments received pursuant to
the Offer. See the discussion regarding backup withholding in "THE TENDER
OFFER--3. Procedures for Tendering Shares." Foreign shareholders should consult
with their own tax advisors regarding withholding taxes in general.

    THE ABOVE DISCUSSION MAY NOT APPLY TO CERTAIN CATEGORIES OF SHAREHOLDERS
SUBJECT TO SPECIAL TREATMENT UNDER THE CODE, SUCH AS FOREIGN SHAREHOLDERS AND
SHAREHOLDERS WHOSE SHARES WERE ACQUIRED PURSUANT TO THE EXERCISE OF ANY EMPLOYEE
STOCK OPTION OR OTHERWISE AS COMPENSATION. SHAREHOLDERS ARE URGED TO CONSULT
THEIR OWN TAX ADVISORS TO DETERMINE THE SPECIFIC TAX CONSEQUENCES OF THE OFFER
AND THE MERGER, INCLUDING ANY FEDERAL, STATE, LOCAL OR OTHER TAX CONSEQUENCES
(INCLUDING ANY TAX RETURN FILING OR OTHER TAX REPORTING REQUIREMENTS) OF THE
OFFER AND THE MERGER.

    On July 23, 1999, the last full trading day prior to the announcement of the
execution of the Merger Agreement, the last reported sales price of the Shares
on NASDAQ was $5 11/16 per Share. On July 29, 1999, the last full trading day
prior to the date hereof, the last reported sales price of the Shares on NASDAQ
was $6 1/4 per Share. SHAREHOLDERS ARE URGED TO OBTAIN A CURRENT MARKET
QUOTATION FOR THE SHARES.

7.  EFFECT OF THE OFFER ON THE MARKET FOR THE SHARES; NASDAQ LISTING AND
    EXCHANGE ACT REGISTRATION; MARGIN REGULATIONS

    MARKET FOR THE SHARES.  The purchase of Shares pursuant to the Offer will
reduce the number of holders of Shares and the number of Shares that might
otherwise trade publicly and could adversely affect the liquidity and market
value of the remaining Shares held by the public. Neither Parent nor the
Purchaser can predict whether the reduction in the number of Shares that might
otherwise trade publicly would have an adverse or beneficial effect on the
market price for or marketability of the Shares or whether it would cause future
market prices to be greater or less than the Offer Price.

    NASDAQ NATIONAL MARKET.  The purchase of the Shares tendered in response to
the Offer will reduce the number of Shares that might otherwise trade publicly
and probably will significantly reduce the number of holders of Shares, which
could adversely affect the liquidity and market value of the remaining Shares
held by the public. Depending upon the number of shares of Company Common Stock
purchased pursuant to the Offer, the Shares may no longer meet the standards of
the National Association of Securities Dealers, Inc. (the "NASD") for continued
inclusion in NASDAQ (the top tier market of the Nasdaq Stock Market), which
require that the issuer have at least 200,000 publicly held shares with a market
value of $1 million held by at least 400 stockholders (or 300 stockholders
holding round lots) and have net tangible assets of at least $1 million, $2
million or $4 million depending on profitability levels during the issuer's four
most recent fiscal years. If these standards are not met, the Company Common
Stock might nevertheless continue to be included in the NASDAQ with quotations
published in the NASDAQ "additional list" or in one of the "local lists."
However, if the number of holders of Company Common Stock falls below 300 or the
number of publicly held Company Common Stock falls below 100,000, or if there
are not at least two market makers for Company Common Stock, the Company Common
Stock would no longer qualify for Nasdaq Stock Market reporting, and the Nasdaq
Stock Market would cease to provide any quotations. Company Common Stock held
directly or indirectly by an officer or director of the Company, or by a
beneficial owner of more than 10% of the Company Common Stock, ordinarily will
not be considered as being publicly held for this purpose. According to the
Company, as of July 28, 1999, there were approximately 272 holders of record of
the Company Common Stock and approximately 9,800 beneficial owners and
22,030,723 shares of Common Stock were outstanding. If, as a result of the
purchase of Company Common Stock pursuant to the Offer or otherwise, the Company
Common Stock no longer meet the NASD requirements for continued inclusion on
NASDAQ or in any other tier of the Nasdaq Stock Market, the market of the
Company Common Stock could be adversely affected.

                                       13
<PAGE>
    If the Common Shares no longer meet the requirements for inclusion in any
tier of the Nasdaq Stock Market, quotations might or might not still be
available from other sources. The extent of the public market, and availability
of quotations, for the Common Shares would depend upon the number of holders of
Common Stock after the purchase of the Shares tendered in response to the Offer,
whether securities firms are interested in maintaining a market in the Common
Shares, the possible termination of registration under the Exchange Act, as
described below, and other factors.

    EXCHANGE ACT REGISTRATION.  The Shares currently are registered under the
Exchange Act. Registration of the Shares under the Exchange Act may be
terminated upon application of the Company to the Commission if the Shares are
neither listed on a national securities exchange nor held by 300 or more holders
of record. Termination of registration of the Shares under the Exchange Act
would substantially reduce the information required to be furnished by the
Company to its shareholders and to the Commission and would make certain
provisions of the Exchange Act no longer applicable to the Company, such as the
short-swing profit recovery provisions of Section 16(b) of the Exchange Act, the
requirement of furnishing a proxy statement pursuant to Section 14(a) of the
Exchange Act in connection with shareholders' meetings and the related
requirement of furnishing an annual report to shareholders and the requirements
of Rule 13e-3 under the Exchange Act with respect to "going private"
transactions. Furthermore, the ability of "affiliates" of the Company and
persons holding "restricted securities" of the Company to dispose of such
securities pursuant to Rule 144 or 144A promulgated under the Securities Act may
be impaired or eliminated. If registration of the Shares under the Exchange Act
were terminated, the Shares would no longer be "margin securities" or be
eligible for NASDAQ reporting.

    If registration of the Company Common Stock is not terminated prior to the
Merger, then the Company Common Stock will be delisted from all stock exchanges
and the registration of the Company Common Stock under the Exchange Act will be
terminated following the consummation of the Merger.

    MARGIN REGULATIONS.  The Shares are currently "margin securities" under the
regulations of the Board of Governors of the Federal Reserve System (the
"Federal Reserve Board"), which has the effect, among other things, of allowing
brokers to extend credit on the collateral of the Shares. Depending upon factors
similar to those described above regarding listing and market quotations, it is
possible that, following the Offer, Shares would no longer constitute "margin
securities" for the purposes of the margin regulations of the Federal Reserve
Board and therefore could no longer be used as collateral for Loans made by
brokers.

    OTHER FINANCIAL INFORMATION. During the course of the discussions between
Parent and the Company that led to the execution of the Merger Agreement, the
Company provided Parent with financial projections and other information
relating to the Company which is not publicly available. The information
included projections of the Company's estimated revenues, net income (loss) and
earnings per share as an independent Company (i.e., without regard to the impact
to the Company of a transaction with Parent) of

                                       15
<PAGE>
approximately: $(18.6) million, $5.2 million $17.5 million, and $23.0 million,
and $($0.85), $0.23, $0.73, $0.92 per share, respectively, for the years 1999,
2000, 2001 and 2002, respectively. The foregoing projections were prepared
solely for internal use and not for publication or with a view to complying with
the published guidelines of the Commission regarding projections or with the
guidelines established by the American Institute of Certified Public
Accountants. The projections are "forward-looking" and inherently subject to
significant uncertainties and contingencies, many of which are beyond the
control of the Company, including: potentially adverse changes in laws,
regulations or rules applicable to the Company or the pharmaceutical industry
generally; changes in the demand and competition for pharmaceuticals and similar
products, dependence on collaborative partners, capital requirements, risk of
manufacturing scale-up, product commercialization, including delays of
introductions of new products or enhancements, size and timing of individual
orders, rapid technolgical changes, acquisitions of marketing and sales
distribution organizations, market acceptance of new products, regulatory
approvals, future competition; general business and economic conditions; changes
in tax and accounting matters affecting the Company; and other matters.
Representatives of the Company have informed Parent that certain of the
assumptions used by the Company in preparing the projections have changed
significantly. Accordingly, the Company's actual results over the periods
indicated may differ materially than those described above. The inclusion of
this information should not be regarded as an indication that Parent, the
Purchaser, the Company or anyone who received this information considers it a
reliable predictor of future events, and this information should not be relied
upon as such. This information is being included in this Offer to Purchase only
because it was furnished by the Company to Parent. None of Parent, the Purchaser
or the Company assumes any responsibility for the validity, reasonableness,
accuracy or completeness of the projections, and the Company has made no
representations to Parent or the Purchaser regarding the financial projections
described above.

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

(1) For purposes for reporting under U.S. GAAP, Parent accounts for compensation
    expense for certain employee stock option plans under the provisions of
    Accounting Principles Board Opinion 25. No such expense is required to be
    determined under Canadian GAAP. As such, the compensation expense not
    reported under Canadian GAAP for years ended December 31, 1998, 1997, and
    1996, six months ended June 30, 1999 and 1998 was $2,237,000, $1,669,000,
    $620,000, $900,000 and $1,888,000 respectively.

    For purposes for reporting under U.S. GAAP, net-income is reduced by a
    non-cash charge representing amortization of a warrant subscription
    receivable, which is a contra equity account which under U.S. GAAP would
    have been offset against shareholders' equity at the time of the initial
    public offering of Intelligent Polymers, a company organized by Parent. As
    such, initial amortization expense reported under U.S. GAAP for years ended
    December 31, 1998 and 1997, six months ended June 30, 1999 and 1998 was
    $1,179,000, $750,000, $1,397,000, and $537,000 respectively.

    For purposes of reporting under U.S. GAAP, companies are required to write
    off certain product launch and advertising costs incurred during the year.
    This adjustment represents the portion of product launch and advertising
    costs deferred under Canadian GAAP and required to be written off under U.S.
    GAAP. Net income for the year ended December 31, 1998 and six months ended
    June 30, 1999 is $426,000 and ($238,000) respectively, less than net income
    for such periods under Canadian GAAP.

(2) Under U.S. GAAP, specifically SFAS No. 115, "Accounting for Certain
    Investments in Debt and Equity Securities", Parent has classified certain of
    its long term investments as securities available-for-sale and reported as
    fair value, with unrealized gains and losses excluded from earnings and
    reported in a separate component of shareholders' equity. Under Canadian
    GAAP, the long-term investment is reported at the lower of cost and net
    realizable value.

    The name, citizenship, business address, principal occupation or employment
and five-year employment history for each of the directors and executive
officers of Parent and the Purchaser are set forth in Schedule I hereto.

                                       19
<PAGE>
    Except as described in this Offer to Purchase, none of Parent or the
Purchaser or, to the best knowledge of Parent or the Purchaser, any of the
persons listed in Schedule I hereto or any associate or majority-owned
subsidiary of Parent, the Purchaser or such persons beneficially owns any equity
securities of the Company, and none of Parent or the Purchaser or, to the best
knowledge of Parent or the Purchaser, any of the persons referred to above, or
any of the respective directors, executive officers or subsidiaries of any of
the foregoing has effected any transaction in any equity security of the Company
during the past 60 days.

    Except as described in this Offer to Purchase, none of Parent or the
Purchaser or, to the best knowledge of Parent or the Purchaser, any of the
persons listed in Schedule I hereto has any contract, arrangement, understanding
or relationship with any other person with respect to any securities of the
Company, including, without limitation, any contract, arrangement, understanding
or relationship concerning the transfer or the voting of any securities of the
Company, joint ventures, loan or option arrangements, puts or calls, guarantees
of loans, guarantees against loss or the giving or withholding of proxies.
Except as described in this Offer to Purchase, none of Parent or the Purchaser
or, to the best knowledge of Parent or the Purchaser, any of the persons listed
in Schedule I hereto has had any transactions with the Company or any of its
executive officers, directors or affiliates that would require reporting under
the rules of the Commission.

    There are no directors in common between the Parent and the Company and no
director or officer of the Parent holds any shares or options of the Company.

    Except with respect to the transactions contemplated by the Merger
Agreement, the Option Agreement (as defined in "THE TENDER OFFER--11. Background
of the Offer and the Merger; Contacts with the Company") and the Escrow
Agreement (as defined in "THE TENDER OFFER--11. Background of the Offer and the
Merger; Contacts with the Company") and as described in this Offer to Purchase,
there have been no contacts, negotiations or transactions between Parent or the
Purchaser, or their respective subsidiaries, or to the best knowledge of Parent
or the Purchaser, any of the persons listed in Schedule I hereto, on the one
hand, and the Company or its executive officers, directors or affiliates, on the
other hand, concerning a merger, consolidation or acquisition, tender offer or
other acquisition of securities, election of directors or a sale or other
transfer of a material amount of assets.

    Parent and its affiliates have, from time to time, had contractual
relationships with the Company and its affiliates in the ordinary course of
their respective businesses. Parent is a customer of the Company and most
recently, in December 1997, entered into a contract with the Company to conduct
development studies with respect to a Parent drug.

                                       20

    AVAILABLE INFORMATION.  Parent is subject to the information and reporting
requirements of the Business Corporations Act (Ontario), Canadian provincial
securities laws and the rules of the Toronto Stock Exchange ("TSE") and the NYSE
and the Exchange Act (applicable to foreign issuers) and in accordance therewith
files periodic reports and other information with securities regulatory
authorities in Canada, the TSE, the NYSE and the Commission, relating to its
business, financial condition and other matters. Parent is required to disclose
in such reports certain information, as of particular dates, concerning Parent's
directors and officers, their compensation, stock options granted to them, the
principal holders of Parent's securities and any material interest of such
persons in transactions with Parent. Copies of such documents are also available
to shareholders on request to Parent's Secretary. The reports and other
information filed by Parent with the Commission can be inspected and copied at
the public reference facilities maintained by the Commission at Room 1024, 450
Fifth Street, N.W., Washington, D.C. 20549, and at the Regional Offices of the
Commission located at 7 World Trade Center, 13th Floor, New York, New York
10048, and Citicorp Center, 500 West Madison Street, Chicago, Illinois
60661-2511. Copies of such material can also be obtained by mail from the Public
Reference Section of the Commission at 450 Fifth Street, N.W., Washington, D.C.
20549, at prescribed rates. The Commission maintains an internet web site that
contains reports, proxy and information statements and other information
regarding registrants that file electronically with the Commission
(http://www.sec.gov). Although Parent may not be required to file electronically
materials which would be required to be filed electronically by domestic
issuers, it is the current intention of Parent to make such material available
electronically. In addition, such material may be inspected and copied at the
offices of the NYSE, 20 Broad Street, New York, New York 10005, on which
exchange Parent's shares are listed.

10. SOURCE AND AMOUNT OF FUNDS

    The Purchaser estimates that the total amount of funds required to acquire
the shares of common stock of the Company beneficially owned by it at the time
of commencement of the Offer, to consummate the Offer and the Merger and to pay
related fees and expenses will be approximately $85 million. See "THE TENDER
OFFER--12. Purpose of the Offer and the Merger; Plans for the Company" and "THE
TENDER OFFER--16. Fees and Expense." The Purchaser expects to obtain these funds
from Parent by means of a capital contribution or advance at the time Shares
tendered pursuant to the Offer are accepted for payment. Parent, in turn,
expects to obtain the funds necessary to make the capital contribution from cash
on hand. Certain covenants in Parent's Indenture with respect to its outstanding
10 7/8% Senior Notes (the "Indenture") currently limit the amount Parent can
invest to acquire the stock of an entity which is less than 50% owned by Parent.
Parent may seek a waiver of this limitation or, in lieu of such waiver, issue
common shares in a private placement in an amount sufficient to overcome this
limitation. No final decision has been made by Parent concerning the method to
be used to satisfy the requirements of the Indenture. The Offer is not
conditioned on obtaining financing. The covenant provision in Parent's Indenture
is not applicable to the Merger. In addition, Parent understands that upon
consummation of the Merger the holders of the 7% Convertible Subordinated
Debentures due 2004 of the Company (the "Convertible Debentures") will have the
right to require the Surviving Company to offer to purchase such debentures at
100% of the principal amount. The Company's annual report states that the
outstanding principal amount of the Convertible Debentures as of the date hereof
is $75 million.

11. BACKGROUND OF THE OFFER AND THE MERGER; CONTACTS WITH THE COMPANY

    Parent, a global integrated pharmaceutical company specializing in the
development of advanced oral controlled-release drugs, has identified as a
strategic objective the expansion of its pipeline of products and drug delivery
platforms. The management and Board of Directors of Parent have periodically
reviewed various expansion strategies, including but not limited to the
possibility of internal investments, joint ventures and strategic alliances and
acquisitions and business combinations with companies participating in the oral
pharmaceuticals industry.

                                       21
<PAGE>
    In early 1997, the then Chief Executive Officer of the Company contacted the
Chairman of Parent to discuss the possibility of a business relationship between
the two companies. On April 17, 1997, members of the senior management of the
companies met at the Company's business premises in Chantilly, Virginia, to
discuss potential business collaborations between Parent and the Company.

    Later in 1997, further discussions occurred and a number of meetings were
held between scientific representatives of the Company and Parent regarding a
possible agreement for the development of a specific drug of Parent. During this
period, Parent undertook an extensive review of the Company's technology
platform for the purpose of implementing a proposed development agreement. A
development agreement was executed on December 18, 1997 pursuant to which the
Company undertook development work with respect to the incorporation of its
patented technology into a drug Parent was developing. Implementation of the
development agreement required numerous additional contacts between
representatives of Parent and representatives of the Company during 1998.

    In early June, 1999, the Chairman of Parent and the Chairman of the Company
began to discuss potential business alliances between Parent and the Company. In
the course of such discussions, it was decided that both companies would
consider the feasibility of a business combination. The Chairman of Parent and
the Chairman of the Company had numerous discussions concerning a possible
combination between the two entities.

    In late June, 1999, the Chairman of Parent and the Chairman of the Company
discussed the possibility of Parent acquiring the shares Company Common Stock
owned by the Chairman of the Company and retaining the Chairman as a consultant
following a possible acquisition. The Chairman of Parent expressed the position
that the grant of an option for the shares of Company Common Stock was a
necessary condition to the Parent's further exploration of a transaction between
the two companies. He orally proposed the terms of a possible option agreement
for these shares and suggested various alternatives relating to the acquisition
of the Company. On June 30, 1999, the Chairman of Parent submitted a preliminary
draft of the terms of such an option with the understanding that such an option
would be the first step towards a possible acquisition of the Company.

    On July 2, 1999, representatives of Parent and of the Chairman of the
Company discussed the terms of an option and a related escrow arrangement
without reaching an agreement or understanding.

    On July 6, 1999, the Board of Directors of the Company approved, for
purposes of Section 203 of the General Corporation Law of the State of Delaware,
a possible option agreement between the Parent and the Chairman of the Company
and the acquisition of the Chairman's shares in the Company thereunder.

    On July 6, 1999, July 8, 1999 and July 12, 1999 representatives of Parent,
representatives of the Chairman of the Company and representatives of the
Company discussed the terms of the option, the terms of a potential acquisition
transaction and the possibility of entering into a confidentiality agreement.

    On July 9, 1999, counsel for the Chairman of the Company submitted a draft
of a consulting agreement and a form of a letter agreement to Parent which,
together, provided for the Chairman of the Company to provide business,
strategic, marketing, business planning, special projects and other consulting
services to Parent. The form of consulting agreement imposes certain
restrictions on the Chairman of the Company with respect to competitive
activities and Parent's employees, customers and suppliers. The consulting
agreement would be effective if Parent, having exercised its option to acquire
the shares of Company Common Stock owned by the Chairman of the Company,
acquires more than 50% of the Company. If the consulting agreement becomes
effective, the Chairman of the Company is entitled to receive a fee of
$2,000,000 on the first anniversary of the effective date, provided that if
Parent has acquired an interest of 80% or more in the Company prior to July 13,
2010 the Chairman of the Company will be entitled to receive a fee of $500,000
per calendar quarter until he has received aggregate fees under the consulting
agreement of $6,000,000.

    On July 13, 1999, the Chairman of Parent, representatives of Parent, the
Chairman of the Company and representatives of the Chairman of the Company
negotiated the terms of an option agreement

                                       22
<PAGE>
between the Chairman of the Company and Parent and an escrow to hold the option
shares and the purchase price after the exercise of the option. On that date
Parent and the Chairman of the Company entered into an option agreement (the
"Option Agreement") which granted Parent a ten day option to purchase all the
shares of the Company owned by the Chairman of the Company at a price of $7.00
per share and the letter agreement providing that Parent and the Chairman of the
Company would enter into a consulting agreement on the terms outlined above.
Parent, the Chairman of the Company and a bank acting as escrow agent entered
into an escrow agreement (the "Escrow Agreement") which provided for
distribution of the option shares and the purchase price upon termination of the
waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976
and the Chairman of the Company made arrangements to deposit his shares into
escrow pending exercise or termination of the option period. If the option
shares and the purchase price are not distributed as provided in the preceding
sentence by October 31, 1999, the option shares will be returned to the Chairman
of the Company and the purchase price will be returned to Parent.

    Also on July 13, 1999, representatives of Parent and representatives of the
Company negotiated the terms of a confidentiality agreement and discussed the
timing of due diligence. Parent and the Company entered into a confidentiality
agreement relating to the Company's confidential information which also granted
Parent an exclusivity period, subject to the fiduciary obligations of the
Company's Board of Directors, terminating July 26, 1999 while it conducted its
due diligence.

    On July 14, 15 and 16, 1999, numerous representatives of Parent, including
its entire senior management team, regulatory consultants and intellectual
property and licensing attorneys, conducted due diligence at the Company's
Chantilly, Virginia premises. In the course of the due diligence investigations,
the senior management representatives of Parent met individually and
collectively with key executive, scientific and management personnel of the
Company.

    On July 19, 1999, the General Counsel of Parent contacted Mr. D. Tierny, a
member of the Board of Directors of the Company, to discuss with him possibility
of Parent's acquisition of one million shares of the Company, the legal
ownership of which was the lodged in Westbury Ltd. (as to 900,000 of such
shares) and Salisbury Ltd. (as to 100,000 of such shares).

    On July 19 and 20, 1999, various representatives of Parent continued due
diligence at the Company's Chantilly, Virginia premises.

    At about the same time, the Company executed a confidentiality agreement
relating to Parent's confidential information. On July 19, 20 and 21, 1999,
various representatives of the Company conducted due diligence at Parent's
Mississauga, Ontario, Canada premises. In the course of that investigation,
various representatives of the Company met with representatives of Parent for
the purpose of determining, clarifying or enhancing their due diligence
requirements.

    During the period from July 22, 1999 through July 25, 1999, representatives
of Parent and representatives of the Company negotiated the terms of a
definitive merger agreement.

    On July 22, 1999, the General Counsel of Parent and Mr. Tierny agreed that
Parent would purchase from Salisbury Ltd. and Westbury Ltd., their entire
shareholdings in the Company at $7.00 per share.

    On July 22, 1999 and July 23, 1999 the Board of Directors of Parent met and
approved the proposed terms of the Merger Agreement and adopted resolutions
ratifying the negotiations to date, approving the possible acquisition of the
Company and authorizing the appropriate officers of Parent to negotiate the
terms of and enter into a definitive Merger Agreement.

    On July 23, 1999, Purchaser was formed and its Board of Directors met and
approved the proposed terms of the Merger Agreement and adopted resolutions
ratifying the negotiations to date, approving the possible acquisition of the
Company and authorizing the appropriate officers of Parent to negotiate the
terms of and enter into a definitive Merger Agreement.

    On July 23, 1999 Parent and the Chairman of the Company extended the option
period until 11:59 p.m. Prior to such time, Parent wired payment to the escrow
agent and exercised its option.

                                       23
<PAGE>
    On July 23, 1999, Westbury Ltd. and Salisbury Ltd. confirmed by letter to
Parent their agreement to sell their respective shares to Parent, subject to a
restriction on the transfer of certain of such shares which expires on September
1, 1999.

    On July 25, 1999, Parent acknowledged by letter its agreement with Westbury
Ltd. and Salisbury Ltd. to consummate the purchase of their respective shares
following the termination or expiration of a possible tender offer.

    On July 25, 1999, the Board of Directors of the Company approved the Merger
Agreement, the Offer and the Merger. The factors considered in approving the
Merger Agreement, the Offer and the Merger, and in recommending that
shareholders tender their Shares pursuant to the Offer, are described in the
Company's Solicitation/Recommendation Statement on Schedule 14D-9, which is
being mailed to shareholders of the Company herewith.

    On July 25, 1999, the parties executed the Merger Agreement and, on July 26,
1999, publicly announced the transaction.

12. PURPOSE OF THE OFFER AND THE MERGER; PLANS FOR THE COMPANY; THE MERGER
    AGREEMENT

    PURPOSE OF THE OFFER AND THE MERGER.  The purpose of the Offer is to enable
Parent to acquire a significant equity interest in the Company. Following the
Offer, Parent and Purchaser intend to acquire the remaining equity interest in
the Company not acquired in the Offer by consummating the Merger. Upon
consummation of the Merger, the Surviving Corporation will become a wholly-owned
subsidiary of Parent. Accordingly, the Shares will cease to be publicly traded
and will no longer be quoted on the NASDAQ.

    PLANS FOR THE COMPANY.  It is expected that, initially following the Merger,
the business and operations of the Company will continue without substantial
change and that Parent will integrate the Company with Parent's existing
business. Parent will continue to evaluate the business and operations of the
Company during the pendency of the Offer and the Merger and after the
consummation of the Offer and the Merger, and will take such further actions as
it deems appropriate under the circumstances then existing. Such actions could
include changes in the Company's business, corporate structure, capitalization
or management, although, except as disclosed in this Offer to Purchase, Parent
has no current plans with respect to any of such matters. Following consummation
of the Offer but prior to consummation of the Merger, Parent shall be entitled
to designate such number of directors, rounded up to the next whole number, on
the Board of Directors of the Company as is equal to the product to the total
number of directors on the Board of Directors of the Company (determined after
giving effect to the directors elected pursuant to this sentence) multiplied by
the percentage that the aggregate number of shares beneficially owned by Parent
or its affiliates bears to the total number of Shares then outstanding, and the
Company shall, upon request of Parent, promptly take all actions necessary,
seeking the resignations of one or more existing directors, provided that, prior
to the Effective Time, the members of the Board which are officers, directors or
designees of the Parent shall at all times be less than 50% of the total number
of Board members. Following consummation of the Offer but prior to the
consummation of the Merger, Parent shall also be entitled to designate an
officer of the Company as provided in the Merger Agreement.

THE MERGER AGREEMENT.

    The following is a summary of certain provisions of the Merger Agreement.
The summary is qualified in its entirety by reference to the Merger Agreement
which is incorporated herein by reference and a copy of which has been filed
with the Commission as an exhibit to the Schedule 14D-1. The Merger Agreement
may be examined and copies may be obtained at the place and in the manner set
forth in "THE TENDER OFFER--8. Certain Information Concerning the Company" of
this Offer to Purchase.

    THE OFFER.  The Merger Agreement provides that the Purchaser will commence
the Offer and that, upon the terms and subject to the prior satisfaction or
waiver of the Offer Conditions (which are set forth in "THE TENDER OFFER--14.
Certain Conditions of the Offer"), the Purchaser will purchase such number of
Shares of the Company as will cause Parent and its affiliates to beneficially
own up to 49% of

                                       24
<PAGE>
the outstanding Company Common Stock, but, except as otherwise provided in the
Merger Agreement, not less than 40% of the outstanding Company Common Stock of
the Shares validly tendered pursuant to the Offer. The Merger Agreement provides
that the Purchaser may modify and extend the terms of the Offer as described in
"THE TENDER OFFER--1. Terms of the Offer; Proration; Expiration Date." Subject
to the terms and conditions of the Offer, the Purchaser shall accept for payment
and shall pay, as soon as practicable after the expiration date of the Offer for
Shares validly tendered and not withdrawn (subject to proration, if applicable).
See "THE TENDER OFFER--1. Terms of the Offer; Proration; Expiration Date" and
"THE TENDER OFFER--4. Withdrawal Rights."

    Subject to compliance with applicable law, promptly upon the payment by the
Purchaser or Parent, as the case may be, for Shares pursuant to the Offer, and
from time to time thereafter, Parent shall be entitled to designate a number of
directors which is proportionate to the number of Shares beneficially owned by
Parent or its affiliates, provided, however, that prior to the Effective Time
(as defined), the members of the Board which are officers, directors or
designees of the Parent shall at all times be less than 50% of the total number
of Board members.

    Promptly upon the payment by the Purchaser or Parent, as the case may be,
for Shares pursuant to the Offer, Parent shall be entitled to designate one
officer of the Company (reasonably acceptable to the Company) as described in
the Merger Agreement. Such officer shall report to and serve at the pleasure of
the Board of Directors of the Company; PROVIDED, that such officer shall not be
terminated without the approval of at least two-thirds of the members of the
Board of Directors.

    THE MERGER.  The Merger Agreement provides that, subject to the terms and
conditions thereof, and in accordance with the Delaware General Corporation Law
(the "DGCL"), at the effective time of the Merger (the "Effective Time"), the
Merger will be effected as soon as practicable following the satisfaction or
waiver of certain conditions to the Merger (as outlined in "THE TENDER
OFFER--12. Purpose of the Offer and the Merger; Plans for the Company; the
Merger Agreement") or on such other date as the parties hereto may agree. At the
Effective Time, the Purchaser shall be merged with and into the Company and the
separate corporate existence of the Purchaser shall cease.

    If the Merger is consummated, the Certificate of Incorporation and By-Laws
of Purchaser, each as in effect immediately prior to the Effective Time, shall
be the Certificate of Incorporation and By-Laws of the Surviving Corporation,
until amended in accordance with the provisions thereof, the Merger Agreement
and applicable law.

    CONSIDERATION TO BE PAID IN THE MERGER.  In the Merger, each Share (other
than Shares held by Parent, the Purchaser, any direct or indirect wholly-owned
subsidiary of Parent, in the treasury of the Company or by any direct or
indirect wholly-owned subsidiary of the Company) issued and outstanding
immediately prior to the Effective Time shall be converted into the right to
receive a fraction of a common share of Parent Common Stock, based on an
exchange ratio determined as follows: (i) if the average of the daily closing
prices per share of Parent Common Stock on the NYSE Composite Transactions
Reporting System, as reported in the Wall Street Journal for the fifteen trading
days ending on the date immediately prior to the second full NYSE trading day
immediately preceding the Closing Date (the "Average Trading Price"), is less
than $45.00, the Exchange Ratio shall equal .1556; (ii) if the Average Trading
Price is greater than or equal to $45.00, but less than or equal to $58.625, the
Exchange Ratio shall equal a fraction (rounded to the nearest ten-thousandth)
determined by dividing $7.00 by the Average Trading Price; (iii) if the Average
Trading Price is greater than $58.625 but less than or equal to $62.810, the
Exchange Ratio shall equal .1194 and (iv) if the Average Trading Price is
greater than $62.810, the Exchange Ratio shall equal a fraction (rounded to the
nearest ten-thousandth) determined by dividing $7.50 by the Average Trading
Price (the "Merger Consideration").

    The Merger Agreement provides that each share of Company Common Stock held
by Parent, the Purchaser, any direct or indirect wholly-owned subsidiary of
Parent, in the treasury of the Company or by any direct or indirect wholly-owned
subsidiary of the Company, if any, immediately prior to the Effective

                                       25
<PAGE>
Time shall be canceled and retired and shall cease to exist with no payment
being made with respect thereto.

    In addition, the Merger Agreement provides that each share of common stock,
par value $0.01 per share, of Purchaser issued and outstanding immediately prior
to the Effective Time shall, by virtue of the Merger and without any action on
the part of the holder thereof, be converted into and become the number of
validly issued, fully paid and nonassessable shares of common stock, par value
$.01 per share, of the Surviving Corporation equal to the number of shares of
Common Stock outstanding on a fully diluted basis immediately prior to the
Effective Time.

    RECOMMENDATION.  The Merger Agreement states that the Company's Board of
Directors has (i) determined that the Offer and the Merger are fair to and in
the best interests of the Company and its stockholders, (ii) approved the Offer
and the Merger in accordance with Section 203 of the DGCL and (iii) resolved to
recommend that the Company's stockholders accept the Offer, tender all of their
Shares in response to the Offer and adopt and approve the Merger Agreement and
the Merger. The Board may withdraw, modify or amend its recommendation if it
determines reasonably and in good faith that it is necessary under applicable
law to do so in the exercise of the directors' fiduciary duties after
consultation with outside counsel.

    SURVIVING CORPORATION'S DIRECTORS AND OFFICERS.  Subject to applicable law,
the directors of Purchaser immediately prior to the Effective Time shall be the
initial directors of the Surviving Corporation and shall hold office until their
respective successors are duly elected and qualified, or their earlier death,
resignation or removal. The officers of the Company at the Effective Time shall
be the initial officers of the Surviving Corporation and will hold office from
the Effective Time until their respective successors are duly elected or
appointed.

    STOCK OPTIONS AND AWARDS.  The Merger Agreement provides that, the Board of
Directors of the Company and the Committee (as defined in the Option Plan (as
defined below)) have adopted such resolutions, and shall take such other actions
as may be necessary, so that each outstanding option (an "Option") granted under
the Company's 1991 Stock Option Plan, 1994 Director Stock Option Plan and 1994
Stock Incentive Plan (collectively, the "Option Plans"), whether or not then
exercisable or vested, shall, if not exercised within five business days, be
terminated immediately prior to the Effective Time.

    APPROVAL REQUIRED; SHAREHOLDERS MEETING.  Under the DGCL, the affirmative
vote of holders of a majority of the outstanding Shares (including any Shares
owned by the Purchaser) is required to approve the Merger. The Board of
Directors of the Company has approved the Offer, the Merger and the Merger
Agreement; consequently, the only additional corporate action of the Company
that is necessary to effect the Merger is approval by the Company's
shareholders. See also "--Conditions to the Merger" and "Certain Conditions of
the Offer" for a discussion of other conditions that must be satisfied prior to
the consummation of the Offer and the Merger.

    Pursuant to the Merger Agreement, the Company will duly call a special
meeting of its shareholders (the "Company Shareholders Meeting") as soon as
practicable following the acceptance for payment of and payment for Shares by
the Purchaser pursuant to the Offer for the purpose of voting upon the Merger
Agreement, whether or not the Board of Directors determines at any time
subsequent to the July 25, 1999 meeting of the Company's Board of Directors that
this Agreement is no longer advisable and recommends that Shareholders reject
it. The Merger Agreement provides that in connection with the Company
Shareholders Meeting, the Company shall prepare and file with the Commission a
preliminary proxy statement (the "Company Proxy Statement") relating to the
Merger and the Merger Agreement and that Parent shall file a registration
statement, in which the Company Proxy Statement shall be included (the
"Registration Statement" and together with the Company Proxy Statement, the
"Proxy Statement/ Prospectus") with respect to the issuance of Parent Common
Stock in the Merger. Each of Parent and the Company shall use all commercially
reasonable best efforts to have such Proxy Statement/Prospectus and any
supplement or amendment thereto cleared by the Commission and the Registration
Statement declared effective by the Commission. The Proxy Statement/Prospectus
will be mailed to the shareholders of the Company prior to the Company
Shareholders Meeting. The Company has agreed, subject to its fiduciary duties
under applicable law, as advised by outside counsel, to include in the proxy
statement the recommendation of the Board of Directors that shareholders of the
Company vote in favor of the approval of the Merger and the adoption of the
Merger Agreement; provided, however, that notwithstanding any withdrawal,
modification or amendment of the recommendation of the Board of Directors of the
Company made at the Company Board Meeting, the Company agrees that the Merger
Agreement shall be submitted to the Shareholders for approval and adoption at
the Special Meeting whether or not the Board of Directors determines at any time
subsequent to the Company Board Meeting that the Merger Agreement is no longer
advisable and recommends that Shareholders reject it. Parent agrees that it will
vote, or cause to be voted, all of the Shares then owned by it, the Purchaser or
any of its other subsidiaries or affiliates in favor of the approval of the
Merger and the adoption of the Merger Agreement.

                                       26
<PAGE>
    THE OFFER DOES NOT CONSTITUTE A SOLICITATION OF PROXIES FOR ANY MEETING OF
THE SHAREHOLDERS OF THE COMPANY. ANY SUCH SOLICITATION WHICH THE COMPANY, PARENT
OR THE PURCHASER MIGHT MAKE WOULD BE MADE ONLY PURSUANT TO SEPARATE PROXY OR
SOLICITATION MATERIALS COMPLYING WITH THE REQUIREMENTS OF SECTION 14(A) OF THE
EXCHANGE ACT, AND THE RULES AND REGULATIONS PROMULGATED THEREUNDER.

    NO APPRAISAL RIGHTS.  In accordance with Section 262(b) of the DGCL, no
holder of shares of Company Common Stock shall be entitled to appraisal rights.

    INTERIM OPERATIONS.  Except as required by the Merger Agreement or with the
prior written consent of Parent, during the period from the date of the Merger
Agreement to the Effective Time, the Company has agreed to conduct its
operations only in the ordinary course of business consistent with past
practice. In addition, subject to certain exceptions, the Company will not,
prior to the Effective Time, without the prior written consent of Parent: amend
its organizational documents; modify existing compensation arrangements except
in the ordinary course of business consistent with past practice; acquire or
dispose of any assets; incur, assume or pre-pay any debt; modify, amend or
terminate any material contracts; change its accounting methods; adopt a plan of
liquidation or take certain other actions.

    NO SOLICITATION.  The Merger Agreement provides that neither the Company nor
any of the Subsidiaries has any agreement, arrangement or understanding
regarding an Acquisition Transaction (as defined below) with any party
expressing an interest in an Acquisition Transaction that, directly or
indirectly, would be violated, or require any payments, by reason of the
execution, delivery and/or consummation of the Merger Agreement. The Company
shall, and shall cause the Subsidiaries and its and their officers, directors,
employees, investment bankers, attorneys and other agents and representatives
to, immediately cease any existing discussions or negotiations with any person
other than Parent or the Purchaser (a "Third Party") heretofore conducted with
respect to any Acquisition Transaction. The Company shall not, and the Company
shall cause the Subsidiaries and its and their respective officers, directors,
employees, investment bankers, attorneys and other agents and representatives
not to, directly or indirectly, (x) solicit, initiate, continue, facilitate or
encourage (including by way of furnishing or disclosing non-public information)
any inquiries, proposals or offers from any Third Party with respect to, or that
could reasonably be expected to lead to, (i) any acquisition or purchase of 25%
or more of the assets or business of the Company and its Subsidiaries, taken as
a whole or a 25% or more voting equity interest in (including by way of a tender
offer), or (ii) any amalgamation, merger, consolidation or business combination
with, or any recapitalization or restructuring, or any similar transaction
involving, the Company (the foregoing clauses (i) and (ii) being referred to
collectively as an "Acquisition Transaction"), or (y) negotiate, explore or
discuss in any way with any Third Party with respect to any Acquisition
Transaction or enter into, approve or recommend any agreement, arrangement or
understanding requiring the Company to abandon, terminate or fail to consummate
the Offer and/or the Merger or any other transaction contemplated under the
Merger Agreement. Notwithstanding anything to the contrary in the foregoing, the
Company may, prior to the Company Special Meeting, in response to an unsolicited
written proposal with respect to an Acquisition Transaction involving the
acquisition of all or substantially all of the Shares (or all or substantially
all of the assets of the Company and the Subsidiaries) from a Third Party (i)
furnish or disclose non-public information to such Third Party, (ii) negotiate,
discuss or otherwise communicate with such Third Party and (iii) in the case of
an unsolicited tender offer for Shares, withdraw or modify (or resolve to
withdraw or modify) in a manner adverse to Parent the approval or recommendation
of the Merger Agreement and the transactions contemplated hereby or recommend
(or resolve to recommend) such Acquisition Transaction with a Third Party to
Shareholders, (including disclosing to the Company's stockholders such position
contemplated by Rules 14d-9 and 14e-2 promulgated under the Exchange Act) in
each case only if the Board of Directors of the Company determines reasonably
and in good faith: (1) after consultation with and based (as to legal matters)
upon advice of outside counsel that it is required to do so in the exercise of
its fiduciary obligations, (2) (after

                                       27
<PAGE>
consultation with its financial advisor) that such proposed Acquisition
Transaction or tender offer is more favorable to the Shareholders from a
financial point of view than the transaction contemplated under the Merger
Agreement (including any adjustment to the terms and conditions proposed by
Parent and the Purchaser in response to such proposed Acquisition Transaction (a
proposal with respect to such Acquisition Transaction meeting the requirements
of clauses (1) and (2) is referred to herein as a "Superior Proposal"). Prior to
furnishing or disclosing any non-public information to such Third Party, the
Company shall receive from such Third Party an executed confidentiality
agreement with terms no less favorable in the aggregate to the Company than
those contained in the Confidentiality Agreement between the Company and Parent
(the "Confidentiality Agreement"), but which confidentiality agreement shall not
provide for any exclusive right to negotiate with the Company or any payments by
the Company. The Company shall give Parent one day's written notice prior to
entering into any such Confidentiality Agreement. The Company shall provide to
Parent copies of all such non-public information delivered to such Third Party
concurrently with such delivery. Notwithstanding the foregoing, the Board of
Directors of the Company shall not, and the Company shall not, withdraw or
modify (or resolve to withdraw or modify) in a manner adverse to Parent the
approval or recommendation of the Merger Agreement or any of the transactions
contemplated hereby, or recommend (or resolve to recommend) an Acquisition
Transaction with a Third Party to the Shareholders or enter into a definitive
agreement with respect to a Superior Proposal unless (x) the Company has given
Parent three business days' notice of the intention of the Board of Directors to
withdraw or modify (or resolve to withdraw or modify) in a manner adverse to
Parent the approval or recommendation of the Merger Agreement or any of the
transactions contemplated under the Merger Agreement, or recommend (or resolve
to recommend) an Acquisition Transaction with a Third Party to the Shareholders
or the intention of the Company to enter into such definitive agreement, as the
case may be, (y) if Parent makes a counter-proposal within such three business
day period, the Board of Directors of the Company shall have determined, in
light of any such counter-proposal, that the Third Party Acquisition Transaction
proposal is still a Superior Proposal, and (z) the Company concurrently
terminates the Merger Agreement in accordance with the terms hereof and pays any
Termination Fee (as defined in the Merger Agreement) required under Section
8.03(b) of the Merger Agreement.

    The Company shall promptly (but in any event within one day of the Company
becoming aware of same) advise Parent of the receipt by the Company, any of the
Subsidiaries or any of its or their bankers, attorneys or other agents or
representatives of any inquiries or proposals relating to an Acquisition
Transaction and any actions taken pursuant to Section 6.06(a) of the Merger
Agreement. The Company shall promptly (but in any event within one day of the
Company becoming aware of same) provide Parent with a copy of any such inquiry
or proposal in writing and a written statement with respect to any such
inquiries or proposals not in writing, which statement shall include the
identity of the parties making such inquiries or proposal and all the material
terms thereof. The Company shall, from time to time, promptly (but in any event
within one day of the Company becoming aware of same) inform Parent of the
status and content of and developments with respect to any discussions regarding
any Acquisition Transaction with a Third Party. The Company shall, from time to
time, promptly (but in any event within one day of the Company becoming aware of
same) inform Parent in writing of: (i) the calling of meetings of the Board of
Directors of the Company to take action with respect to such Acquisition
Transaction, (ii) the execution of any letters of intent, memoranda of
understanding or similar non-binding agreements with respect to such Acquisition
Transaction, (iii) the waiver of any standstill agreement to which the Company
is or becomes a party, (iv) the determination by the Board of Directors of the
Company to recommend to the Shareholders that they approve or accept a Superior
Proposal or withdraw or modify in a manner adverse to the Parent its approval or
recommendation of the Merger Agreement or the transactions contemplated under
the Merger Agreement, (v) the determination by the Company to publicly disclose
receipt of a Superior Proposal and (vi) the waiver by the Company of any
confidentiality agreement with a person proposing a Superior Proposal.

                                       28

    DIRECTORS' AND OFFICERS' INSURANCE; INDEMNIFICATION.  The Merger Agreement
provides that Parent agrees that all rights to indemnification now existing in
favor of any director or officer of the Company or its Subsidiaries as provided
in such person's certificate of incorporation or by laws, in an agreement
between any such person and the Company, or otherwise in effect on the date of
the Merger Agreement shall survive the Merger and shall continue in full force

    CONDITIONS TO THE OBLIGATIONS OF PARENT AND PURCHASER.  The Merger Agreement
provides that the obligation of Parent and Purchaser to effect the Merger and to
perform their other obligations to be performed at or subsequent to the Closing
shall be subject to the fulfillment at or prior to the Closing of the following
additional conditions, any one or more of which may be waived by Parent or
Purchaser:

    (a) PERFORMANCE.  The Company shall have performed and complied in all
       material respects with all agreements, obligations and conditions
       required by the Merger Agreement to be performed or complied with by it
       on or prior to the Closing Date, except for those failures to so perform
       or comply which are not willful and those failures, whether or not
       willful, that, individually or in the aggregate, would not either impair
       the Company's ability to consummate the Merger and the other transactions
       contemplated hereby or have a Material Adverse Effect on the Company.

    (b) PURCHASE OF SHARES.  The Purchaser shall have accepted for payment and
       paid for Shares pursuant to the Offer in accordance with the terms of the
       Merger Agreement, unless Purchaser's failure to accept for payment and

       Merger Agreement.

       or comply that, individually or in the aggregate, would not either impair
       the ability of Parent or Purchaser to consummate the Merger and the other
       transactions contemplated under the Merger Agreement or have a Material
       Adverse Effect on Parent.

    (b) PURCHASE OF SHARES.  The Purchaser shall have accepted for payment and
       paid for Shares pursuant to the Offer in accordance with the terms of the

       Merger Agreement.

                                       29

       or other governmental body shall have issued an order (other than a
       temporary restraining order), decree or ruling or taken any other action
       restraining, enjoining or otherwise prohibiting the Merger, and such
       order, decree, ruling or other action shall have become final and

       adversely affect (or materially delay) the ability of Purchaser to

       breaches are capable of being cured prior to the consummation of the

       pay for Shares pursuant to the Offer within 120 days following the date

       contained in the Merger Agreement.

    TERMINATION BY THE COMPANY.  The Merger Agreement may be terminated and the
Merger may be abandoned at any time prior to the Effective Time, before or after

       not be true and correct); provided, however, that if such breach or
       breaches are capable of being cured prior to the consummation of the

       Merger Agreement), only if such breaches shall not be cured within 10
       days of delivery to Parent of written notice of such breach or breaches;

    (c) if (A)(x) the Company proposes entering into a definitive agreement with
       respect to a Superior Proposal or (y) the Board of Directors of the
       Company recommends a Third Party Acquisition Transaction which is an
       unsolicited all cash tender offer for any and all Shares and which
       constitutes a Superior Proposal, (B) the Company gives Parent the three
       business days' notice as required pursuant to the last sentence of
       Section 6.06(a) of the Merger Agreement, (C) if a counter-proposal was
       made by Parent within such three business day period, the Board of
       Directors of the Company has determined, in light of the
       counter-proposal, that the Third Party Acquisition Transaction (or
       proposal therefor) is still a Superior Proposal as required by the last
       sentence of Section 6.06(a) of the Merger Agreement and (D) the Company
       has paid to Parent by wire transfer or immediately available funds to an
       account specified by Parent a fee of $5.5 million immediately prior to
       such termination; or

    (d) if (i) Purchaser fails to commence the Offer as provided in Section 1.01
       of the Merger Agreement, (ii) Purchaser fails to pay for Shares pursuant
       to the Offer within 120 days following the date of the Merger Agreement,
       unless such failure to pay for Shares is the result of the failure of the
       Company to perform any of its covenants and agreements contained in the
       Merger Agreement or (iii) Purchaser terminates the Offer in accordance
       with the provisions of Annex I of the Merger Agreement.

    In the event of termination of the Merger Agreement and abandonment of the
Merger pursuant to Article VIII of the Merger Agreement, no party hereto (or any
of its directors or officers) shall have any liability or further obligation to
any other party to the Merger Agreement, except as provided in Section 8.05 of
the Merger Agreement and except that nothing herein shall relieve any party from
liability for any breach of the Merger Agreement.

                                       31
<PAGE>
    In the event of a termination of the Merger Agreement by Parent pursuant to
Section 8.02(c) of the Merger Agreement then, in any such case, the Company
shall within two business days of such termination pay Parent by wire transfer
or immediately available funds to an account specified by Parent a fee of $5.5
million.

    In the event of a termination of the Merger Agreement (i) pursuant to
Section 8.01(c) based on the Company's actions or omission or (d) under the
Merger Agreement or (ii) by Parent pursuant to Section 8.02(a) or (b) of the
Merger Agreement, and in the case of either clause (i) or clause (ii), prior to
such termination any person shall have made a proposal with respect to an
Acquisition Transaction with the Company or its stockholders, and, if prior to
or within twelve months after such termination the Company or any subsidiary of
the Company enters into a definitive agreement with a third party with respect
to, or consummates, an Acquisition Transaction, then the Company, as a condition
to and prior to the earlier of entering into any such definitive agreement and
consummating an Acquisition Transaction, shall pay Parent by wire transfer or
immediately available funds to an account specified by Parent, a fee of $5.5
million.

    Parent and Purchaser acknowledge that whenever a fee is payable by the
Company to Parent pursuant Article VIII of the Merger Agreement, payment by the
Company of such fee in accordance with the terms of the applicable paragraph
shall be deemed a release of the Company from all liability under the Merger
Agreement.

13. DIVIDENDS AND DISTRIBUTIONS

    The Merger Agreement provides that the Company shall not, and shall not
permit any of its Subsidiaries to, prior to the Effective Time, without the
prior written consent of Parent: (a) except for issuances of capital stock of
the Subsidiaries to the Company or a wholly-owned Subsidiary, issue, reissue or
sell, or authorize the issuance, reissuance or sale of (1) additional shares of
capital stock of any class, or securities convertible into capital stock of any
class, or any rights, warrants or options (including under any existing option
plans) to acquire any convertible securities or capital stock, other than the
issuance of Shares pursuant to the exercise of Options outstanding on the date
of the Merger Agreement pursuant to the terms thereof as in effect on the date
of the Merger Agreement, or (2) any other securities in respect of, in lieu of,
or in substitution for, Shares outstanding on the date of the Merger Agreement;
(b) declare, set aside or pay any dividend or other distribution (whether in

any combination thereof) in respect of any class or series of its capital stock
other than between any of the Company and any of the wholly-owned Subsidiaries;
or (c) split, combine, subdivide, reclassify or redeem, purchase or otherwise
acquire, or propose to redeem or purchase or otherwise acquire, any shares of
its capital stock, or any of its other securities.

       indirectly, (i) prohibits, or makes illegal, the acceptance for payment,
       payment for or purchase of Shares or the consummation of the Offer, the
       Merger or the other transactions contemplated by the Merger Agreement,
       (ii) renders Purchaser unable to accept for payment, pay for or purchase
       some or all of the Shares, (iii) imposes material limitations on the
       ability of Parent effectively to exercise full rights of ownership of the

       consummation of the Offer with the same effect as if made at and as of
       the consummation of the Offer (except as to any such representation or
       warranty which speaks as of a specific date) shall not be true and
       correct in any respect that is reasonably likely to have a Material
       Adverse Effect on the Company (or if such representations and warranties
       are qualified by reference to materiality or a Material Adverse Effect on
       the Company, shall not be true and correct), (ii) the Company shall have
       failed to perform in all material respects its covenants or agreements
       contained in the Merger Agreement which would have a Material Adverse
       Effect on the Company or materially adversely affect (or materially
       delay) the ability of Purchaser to consummate the Offer or of Parent,
       Purchaser or the Company to consummate the Merger, and the Company has
       not cured such breach within ten business days after notice by Parent or
       Purchaser thereof; or

    (c) it shall have been publicly disclosed that (i) any person or "group" (as
       defined in Section 13(d)(3) of the Exchange Act) shall have acquired or
       entered into a definitive agreement or agreement in principle to acquire
       beneficial ownership of more than 25% of the Shares or any other class of
       capital stock of the Company, through the acquisition of stock, the
       formation of a group or otherwise, or shall have been granted any option,

       authority on the extension of credit generally by banks or other
       financial institutions;

the circumstances (including any action or inaction by Parent) giving rise to
such condition makes it inadvisable to proceed with the Offer or the acceptance
for payment of or payment for the Shares.

                                       33
<PAGE>
    The foregoing conditions (other than the Minimum Condition) are for the sole
benefit of Parent and Purchaser and may be waived by Parent and Purchaser, in
whole or in part at any time and from time to time, in the sole discretion of
Parent and Purchaser. The failure by Parent and Purchaser at any time to
exercise any of the foregoing rights shall not be deemed a waiver of any such
right and each such right shall be deemed an ongoing right which may be asserted
at any time and from time to time.

15. CERTAIN LEGAL MATTERS; REGULATORY APPROVALS

    GENERAL.  Except as otherwise disclosed herein or as set forth in the Merger
Agreement, based on a review of publicly available filings by the Company with
the Commission, neither Parent nor the Purchaser is aware of (i) any license or
regulatory permit that appears to be material to the business of the Company and
its subsidiaries, taken as a whole, that might be adversely affected by the
acquisition of Shares by the Purchaser pursuant to the Offer or the Merger or
(ii) any approval or other action by any governmental, administrative or
regulatory agency or authority, domestic or foreign, that would be required for
the acquisition or ownership of Shares by the Purchaser as contemplated herein.
Should any such approval or other action be required, the Purchaser currently
contemplates that such approval or action would be sought, except as described
below under " -- STATE TAKEOVER STATUTES." While the Purchaser does not
currently intend to delay the acceptance for payment of Shares tendered pursuant
to the Offer pending the outcome of any such matter, there can be no assurance
that any such approval or action, if needed, would be obtained or would be
obtained without substantial conditions or that adverse consequences might not
result to the business of the Company or the Purchaser or that certain parts of
the businesses of the Company or the Purchaser might not have to be disposed of
in the event that such approvals were not obtained or any other actions were not
taken. To the knowledge of Parent or Purchaser, there is no material legal
proceeding currently pending in relation to the Offer to Purchase. The
Purchaser's obligation under the Offer to accept for payment and pay for Shares
is subject to certain conditions. See "THE TENDER OFFER--14. Certain Conditions
of the Offer."

    ANTITRUST COMPLIANCE.  Under the HSR Act, and the rules that have been
promulgated by the Federal Trade Commission and the Antitrust Division of the
Department of Justice, certain acquisition transactions may not be consummated
unless certain information has been furnished to the Antitrust Division and the
FTC and certain waiting period requirements have been satisfied. The acquisition
of Shares pursuant to the Offer and the Merger is subject to such requirements.

    There is a possibility that filings may have to be made with foreign
governments under their pre-merger notification statutes. The filing
requirements of various nations are being analyzed by the parties and, where
necessary, such filings will be made.

    STATE TAKEOVER STATUTES.  A number of states throughout the United States
have enacted takeover statutes that purport, in varying degrees, to be
applicable to attempts to acquire securities of corporations that are
incorporated or have assets, shareholders, executive offices or places or
business in such states. In Edgar v. MITE Corp., the Supreme Court of the United
States held that the Illinois Business Takeover Act, which involved state
securities laws that made the takeover of certain corporations more difficult,
imposed a substantial burden on interstate commerce and therefore was
unconstitutional. However, in CTS Corp. v. Dynamics Corp. of America, the
Supreme Court of the United States held that a state may, as a matter of
corporate law, and, in particular, those laws concerning corporate governance,
constitutionally disqualify a potential acquiror from voting on the affairs of a
target corporation without prior approval of the remaining shareholders;
provided that such laws were applicable only under certain conditions.

    Based on information supplied by the Company, the Purchaser does not believe
that any state takeover statutes purport to apply to the Offer or the Merger.
Neither Parent nor the Purchaser has currently complied with any state takeover
statute or regulation. The Purchaser reserves the right to challenge the
applicability or validity of any state law purportedly applicable to the Offer
or the Merger

                                       34
<PAGE>
and nothing in this Offer to Purchase or any action taken in connection with the
Offer or the Merger is intended as a waiver of such right. If it is asserted
that any state takeover statute is applicable to the Offer or the Merger and if
an appropriate court does not determine that it is inapplicable or invalid as
applied to the Offer or the Merger, the Purchaser might be required to file
certain information with, or to receive approvals from, the relevant state
authorities, and the Purchaser might be unable to accept for payment or pay for
Shares tendered pursuant to the Offer, or be delayed in consummating the Offer
or the Merger. In such case, the Purchaser may not be obliged to accept for
payment or pay for any Shares tendered pursuant to the Offer.

16. FEES AND EXPENSES

    Except as set forth below, neither Parent nor the Purchaser will pay any
fees or commissions to any broker, dealer or other person for soliciting tenders
of Shares pursuant to the Offer.

    Parent has engaged DLJ as the Dealer Manager in connection with the Offer.
In addition, DLJ is acting as financial advisor to Parent in connection with
Parent's effort to acquire the Company. Parent has agreed to pay DLJ a fee of
$500,000 upon the commencement of the Offer. If the Merger is consummated, or if
an alternative transaction were to be completed resulting in the acquisition of
all or substantially all of the business, securities or assets of the Company,
Parent will pay to DLJ a transaction fee of $2,225,000, against which the
$500,000 fee will be credited.

    Parent has also agreed to reimburse DLJ (in its capacity as Dealer Manager
and financial advisor) for its reasonable out-of-pocket expenses, including the
reasonable fees and expenses of its legal counsel, incurred in connection with
its engagement, and to indemnify DLJ and certain related persons against certain
liabilities and expenses in connection with its engagement, including certain
liabilities under the federal securities laws. DLJ renders various investment
banking and other advisory services to Parent and its affiliates and is expected
to continue to render such services, for which it has received and will continue
to receive customary compensation from Parent and its affiliates.

    The Purchaser has retained MacKenzie Partners, Inc. to act as the
Information Agent in connection with the Offer. The Information Agent may
contact holders of Shares by mail, telephone, facsimile, telegraph and personal
interviews and may request brokers, dealers and other nominee shareholders to
forward materials relating to the Offer to beneficial owners of Shares. The
Information Agent will receive reasonable and customary compensation together
with reimbursement for its reasonable out-of-pocket expenses and will be
indemnified against certain liabilities and expenses, including certain
liabilities under the federal securities laws.

    In addition, ChaseMellon Shareholder Services, L.L.C. has been retained as
the Depositary. The Depositary has not been retained to make solicitations or
recommendations in its role as Depositary. The Depositary will receive
reasonable and customary compensation for its services, will be reimbursed for
certain reasonable out-of-pocket expenses and will be indemnified against
certain liabilities and expenses. Brokers, dealers, commercial banks and trust
companies will be reimbursed by the Purchaser for customary mailing and handling
expenses incurred by them in forwarding offering material to their customers.

17. MISCELLANEOUS

    The Offer is not being made to (nor will tenders be accepted from or on
behalf of) holders of Shares in any jurisdiction in which the making of the
Offer or the acceptance thereof would not be in compliance with the laws of such
jurisdiction. Neither the Purchaser nor Parent is aware of any jurisdiction in
which the making of the Offer or the tender of Shares in connection therewith
would not be in compliance with the laws of such jurisdiction. To the extent the
Purchaser or Parent becomes aware of any state law that would limit the class of
offerees in the Offer, the Purchaser will amend the Offer and, depending on the

                                       35
<PAGE>
timing of such amendment, if any, will extend the Offer to provide adequate
dissemination of such information to holders of Shares prior to the expiration
of the Offer.

    NO PERSON HAS BEEN AUTHORIZED TO GIVE ANY INFORMATION OR MAKE ANY
REPRESENTATION ON BEHALF OF THE PURCHASER NOT CONTAINED IN THIS OFFER TO
PURCHASE OR IN THE LETTER OF TRANSMITTAL, AND IF GIVEN OR MADE, SUCH INFORMATION
OR REPRESENTATION MUST NOT BE RELIED UPON AS HAVING BEEN AUTHORIZED.

    This Offer to Purchase contains statements which, to the extent that they
are not recitations of historical fact, constitute "forward looking" statements
within the meaning of Section 27A of the Securities Act and Section 21E of the
Exchange Act. The words "estimate," "anticipate," "project," "intend," "expect,"
and similar expressions are intended to identify forward looking statements. All
forward looking statements involve risks and uncertainties, including, without
limitations, statements and assumptions with respect to future revenues, program
performance and cash flows, the outcome of contingencies, including litigation
and environmental remediation, anticipated costs of capital investments and
planned dispositions, and the consummation of the Offer and the Merger. Readers
are cautioned not to place undue reliance on these forward looking statements
which speak only as of the date of this Offer to Purchase. Parent does not
undertake any obligation to publicly release any revisions to forward looking
statements to reflect events or circumstances or changes in expectations after
the date of this Offer to Purchase or to reflect the occurrence of unanticipated
events. The forward looking statements in this document are intended to be
subject to the safe harbor protection provided by Section 27A of the Securities
Act and 21E of the Exchange Act. For a discussion identifying some important
factors that could cause actual results to vary materially from those
anticipated in the forward looking statements, see Parent's filings with the
Commission.

    Parent and the Purchaser have filed with the Commission a Tender Offer
Statement on Schedule 14D-1 (the "Schedule 14D-1"), together with exhibits,
pursuant to Rule 14d-3 of the General Rules and Regulations under the Exchange
Act, furnishing certain additional information with respect to the Offer and may
file amendments thereto. In addition, the Company has filed with the Commission
the Schedule 14D-9 pursuant to Rule 14d-9 under the Exchange Act setting forth
its recommendation with respect to the Offer and the reasons for such
recommendation and furnishing certain additional related information. The
Schedule 14D-9 is enclosed herewith and the Schedule 14D-1 and any amendments
thereto, including exhibits, should be available for inspection and copies
should be obtainable in the manner set forth in "THE TENDER OFFER--8. Certain
Information Concerning the Company" (except that they will not be available at
the regional offices of the Commission).

Ladies and Gentlemen:

    The undersigned hereby tenders to ABCI Acquisition Sub. Corporation, a
Delaware corporation (the "Purchaser") and a wholly-owned subsidiary of Biovail
Corporation International, an Ontario, Canada corporation ("Parent"), the above
described shares of common stock, $.01 par value (the "Shares"), Fuisz
Technologies Ltd., a Delaware corporation (the "Company") at a price of $7.00
per Share, net to the seller in cash, without interest thereon, upon the terms
and subject to the conditions set forth in the Offer to Purchase, dated July 30,
1999 (the "Offer to Purchase"), and in this Letter of Transmittal (which, as
amended or supplemented from time to time, together with the Offer to Purchase
constitute the "Offer") receipt of which is hereby acknowledged. The undersigned
understands that the Purchaser reserves the right to transfer or assign, in
whole or from time to time in part, to one or more of its subsidiaries or
affiliates the right to purchase all or any portion of the Shares tendered
pursuant to the Offer.

    Upon the terms of the Offer, subject to, and effective upon, acceptance for
payment of and payment for the Shares tendered herewith in accordance with the
terms of the Offer, the undersigned hereby sells, assigns, and transfers to, or
upon the order of, the Purchaser all right, title and interest in and to all of
the Shares that are being tendered hereby (and any and all other Shares or other
securities or rights issued or issuable in respect thereof on or after July 30,
1999) and constitutes and irrevocably appoints ChaseMellon Shareholder Services,
L.L.C. (the "Depositary") the true and lawful agent, attorney-in-fact and proxy
of the undersigned to the full extent of the undersigned's rights with respect
to such Shares with full power of substitution (such power of attorney and proxy
being deemed to be an irrevocable power coupled with an interest), to (a)
deliver Share Certificates (and any such other Shares or securities or rights),
or transfer ownership of such Shares (and any such other Shares or securities or
rights) on the account books maintained by the Book-Entry Transfer Facility,
together in either such case with all accompanying evidences of transfer and
authenticity, to or upon the order of the Purchaser, upon receipt by the
Depositary, as the undersigned's agent, of the purchase price, (b) present such
Shares (and any such other Shares or securities or rights) for transfer on the
books of the Company and (c) receive all benefits and otherwise exercise all
rights of beneficial ownership of such Shares (and any such other Shares or
securities or rights), all in accordance with the terms of the Offer.

    The undersigned hereby irrevocably appoints Eugene N. Melnyk and Kenneth C.

attorneys-in-fact and proxies of the undersigned, each with full power of
substitution, to vote in such manner as each such attorney and proxy or his
substitute shall, in his sole discretion, deem proper, and otherwise act
(including pursuant to written consent) with respect to all of the Shares
tendered hereby (and any and all other Shares or other securities or rights
issued or issuable in respect thereof on or after July 30, 1999) which have been
accepted for payment by the Purchaser prior to the time of such vote or action
which the undersigned is entitled to vote at any meeting of shareholders
(whether annual or special and whether or not an adjourned meeting) of the
Company, or by written consent in lieu of such meeting, or otherwise. This power
of attorney and proxy is coupled with an interest in the Company and in the
Shares and is irrevocable and is granted in consideration of, and is effective
upon, the acceptance for payment of such Shares by the Purchaser in accordance
with the terms of the Offer. Such acceptance for payment shall revoke, without
further action, any other power of attorney or proxy granted by the undersigned
at any time with respect to such Shares and no subsequent powers of attorney or
proxies will be given (and if given will be deemed not to be effective) with
respect thereto by the undersigned. The undersigned understands that the
Purchaser reserves the right to require that, in order for Shares to be deemed
validly tendered, immediately upon the Purchaser's acceptance for payment of
such Shares, the Purchaser is able to exercise full voting rights with respect
to such Shares and other securities, including voting at any meeting of
shareholders then scheduled or acting by written consent without a meeting.

undersigned. Except as stated in the Offer to Purchase, this tender is
irrevocable.

    The undersigned understands that tenders of Shares pursuant to any one of
the procedures described in Section 2 of the Offer to Purchase and in the

or equivalent securities being tendered within the meaning of Rule 14e-4

Certificates not tendered or accepted for payment in the name(s) of the
undersigned. Similarly, unless otherwise indicated under "Special Delivery
Instructions," please mail the check for the purchase price and/or return any
Share Certificates not tendered or accepted for payment (and any accompanying
documents, as appropriate) to the undersigned at the address shown below the

tendering Shares by book-entry transfer may request that any Shares not accepted
for payment be returned by crediting such account maintained at such Book-Entry
Transfer Facility as such shareholder may designate by making an appropriate
entry under "Special Payment Instructions." The undersigned recognizes that the
Purchaser has no obligation pursuant to the "Special Payment Instructions" to
transfer any Shares from the name of the registered holder thereof if the
Purchaser does not accept for payment any of the Shares so tendered.

BOOK ENTRY CONFIRMATION). IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN
RECEIPT REQUESTED, PROPERLY INSURED, IS RECOMMENDED. IN ALL CASES, SUFFICIENT
TIME SHOULD BE ALLOWED TO ENSURE TIMELY DELIVERY.

    No alternative, conditional or contingent tenders will be accepted and no
fractional Shares will be purchased. All tendering shareholders, by execution of
this Letter of Transmittal or a facsimile thereof, waive any right to receive
any notice of the acceptance of their Shares for payment.

3.  INADEQUATE SPACE.  If the space provided herein is inadequate, the
    certificate numbers and/or the number of Shares and any other required
    information should be listed on a separate schedule attached hereto and
    separately signed on each page thereof in the same manner as this Letter of
    Transmittal is signed.

4.  PARTIAL TENDERS. (APPLICABLE TO CERTIFICATE SHAREHOLDERS ONLY)  If fewer
    than all the Shares evidenced by any certificate submitted are to be
    tendered, fill in the number of Shares which are to be tendered in the box
    entitled "Number of Shares Tendered." In such case, new Share Certificate(s)
    for the remainder of the Shares that were evidenced by the old Share
    Certificate(s) will be sent to the registered holder, unless otherwise
    provided in the appropriate box marked "Special Payment Instructions" and/or
    "Special Delivery Instructions" on this Letter of Transmittal, as soon as
    practicable after the acceptance for payment of, and payment for, the Shares
    tendered herewith. All Shares represented by certificates delivered to the
    Depositary will be deemed to have been tendered unless otherwise indicated.

5.  SIGNATURES ON LETTER OF TRANSMITTAL, STOCK POWERS AND ENDORSEMENTS. If this
    Letter of Transmittal is signed by the registered holder(s) of the Shares
    tendered hereby, the signature(s) must correspond exactly with the name(s)
    as written on the face of the Share Certificate(s) without alteration,
    enlargement or any change whatsoever.

    If any of the Shares tendered hereby are owned of record by two or more
joint owners, all such owners must sign this Letter of Transmittal.

    If any tendered Shares are registered in different names on Share
Certificates, it will be necessary to complete, sign and submit as many separate
Letters of Transmittal as there are different registrations of Share
Certificates.

    If this Letter of Transmittal or any Share Certificates or stock powers are
signed by trustees, executors, administrators, guardians, attorneys-in-fact,
officers of corporations or others acting in fiduciary or representative
capacity, such persons should so indicate when signing, and should submit proper
evidence satisfactory to the Purchaser of their authority to so act.

    When this Letter of Transmittal is signed by the registered owner(s) of the
Shares listed and transmitted hereby, no endorsements of Share Certificates or
separate stock powers are required unless payment is to be made to, or Share
Certificates for Shares not tendered or purchased are to be issued in, the name
of a person other than the registered owner(s). Signatures on such Share
Certificates or stock powers must be guaranteed by an Eligible Institution.

    If this Letter of Transmittal is signed by a person other than the
registered owner(s) of the Shares listed, the Share Certificates must be
endorsed or accompanied by appropriate stock powers, in either case signed
exactly as the name or names of the registered owner(s) appear(s) on the Share
Certificates. Signatures on such Share Certificates or stock powers must be
guaranteed by an Eligible Institution.

6.  STOCK TRANSFER TAXES.  Except as set forth in this Instruction 6, the
    Purchaser will pay or cause to be paid any stock transfer taxes with respect
    to the transfer and sale of purchased Shares to it or its order pursuant to
    the Offer for which the Purchaser is liable in connection with the Offer,
    whether or not another person is jointly liable therefor. If, however,
    payment of the purchase price is

                                       8
<PAGE>
    to be made to, or if Share Certificates not tendered or purchased are to be
    registered in the name of, any person other than the registered holder, or
    if tendered Share Certificates are registered in the name of any person
    other than the person(s) signing this Letter of Transmittal, the amount of
    any stock transfer taxes (whether imposed on the registered holder or such
    person) payable on account of the transfer to such person will be deducted
    from the purchase price unless satisfactory evidence of the payment of such
    taxes or exemption therefrom is submitted.

    EXCEPT AS PROVIDED IN THIS INSTRUCTION 6, IT WILL NOT BE NECESSARY FOR
    TRANSFER TAX STAMPS TO BE AFFIXED TO THE CERTIFICATES LISTED IN THIS LETTER
    OF TRANSMITTAL.

7.  SPECIAL PAYMENT AND DELIVERY INSTRUCTIONS.  If a check is to be issued in
    the name of and/or Share Certificates for unpurchased Shares are to be
    returned to a person other than the signer of this Letter of Transmittal or
    if a check is to be sent and/or such Share Certificates are to be returned
    to someone other than the signer of this Letter of Transmittal or to an
    address other than that shown on the front cover hereof, the appropriate
    boxes on this Letter of Transmittal should be completed. Shareholders
    tendering Shares by book-entry transfer may request that Shares not
    purchased be credited to such account maintained at such Book-Entry Transfer
    Facility as such shareholder may designate hereon. If no such instructions
    are given, such Shares not purchases will be returned by crediting the
    account at the Book-Entry Transfer Facility designated above. See
    Instruction 1.

8.  WAIVER OF CONDITIONS.  The Purchaser reserves the absolute right in its sole
    discretion to waive any of the specified conditions of the Offer, in whole
    or in part, in the case of any Shares tendered.

9.  REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES.  Questions and requests for
    assistance or additional copies of the Offer to Purchase and this Letter of
    Transmittal, the Notice of Guaranteed Delivery and the Guidelines for
    Certification of Taxpayer Identification Number on Substitute Form W-9 may
    be directed to the Information Agent at its address set forth below.

10. 31% BACKUP WITHHOLDING; SUBSTITUTE FORM W-9.  Under U.S. Federal income tax
    law, a shareholder whose tendered Shares are accepted for payment is
    required to provide the Depositary with such shareholder's correct taxpayer
    identification number ("TIN") on Substitute Form W-9 below. If the
    shareholder does not provide the Depositary with the correct TIN, the
    Internal Revenue Service (the "IRS") may subject the shareholder or other
    payee to a $50 penalty. In addition, payments that are made to such
    shareholder or other payee with respect to Shares exchanged pursuant to the
    Offer may be subject to 31% backup withholding.

    If backup withholding applies, the Depositary is required to withhold 31% of
any such payments made to the shareholder or other payee. Backup withholding is
not an additional tax. Rather, the tax liability of persons subject to backup
withholding will be reduced by the amount of tax withheld. If withholding
results in an overpayment of taxes, a refund may be obtained from the IRS.

    Certain shareholders (including, among others, all corporations and certain
foreign individuals) are not subject to these backup withholding and reporting
requirements. In order for a foreign individual to qualify as an exempt
recipient, the shareholder must submit a Form W-8, signed under penalties of
perjury, attesting to that individual's exempt status. A Form W-8 can be
obtained from the Depositary. See the enclosed "Guidelines for Certification of
Taxpayer Identification Number on Substitute Form W-9" for more instructions.

    To prevent backup withholding, each tendering shareholder must provide his
or her correct TIN by completing Substitute Form W-9 set forth below, certifying
that the TIN provided is correct (or that the shareholder is awaiting a TIN) and
that (a) the shareholder has not been notified by the IRS that he or she is
subject to backup withholding as a result of failure to report all interest or
dividends or (b) the IRS has

                                       9
<PAGE>
notified the shareholder that he or she is no longer subject to backup
withholding. To prevent possible erroneous backup withholding, exempt
shareholders (other than certain foreign individuals) should certify in
accordance with the enclosed "Guidelines for Certification of Taxpayer
Identification Number on Substitute Form W-9" that such shareholder is exempt
from backup withholding. If a shareholder has been notified by the IRS that he
or she is subject to backup withholding because of underreporting interest or
dividends on his or her tax return, he or she should nevertheless complete and
sign Substitute Form W-9 but should (unless after being so notified by the IRS
he or she received a notification from the IRS that he or she is no longer
subject to backup withholding) cross out item (2) of the certification on the
form.

    The box in Part 3 of the Substitute Form W-9 may be checked if the tendering
shareholder has not been issued a TIN and has applied for a TIN or intends to
apply for a TIN in the near future. If the box in Part 3 is checked, the
shareholder or other payee must also complete the Certificate of Awaiting
Taxpayer Identification Number below in order to avoid backup withholding.
Notwithstanding that the box in Part 3 is checked and the Certificate of
Awaiting Taxpayer Identification Number is completed, the Depositary will
withhold 31% of all payments made prior to the time a properly certified TIN is
provided to the Depositary.

    The shareholder is required to give the Depositary the TIN (e.g., social
security number or employer identification number) of the record owner of the
Shares or of the last transferee appearing on the transfers attached to, or
endorsed on, the Shares. If the Shares are in more than one name or are not in
the name of the actual owner, consult the enclosed "Guidelines for Certification
of Taxpayer Identification Number on Substitute Form W-9" for additional
guidance on which number to report.

11. LOST, DESTROYED OR STOLEN SHARE CERTIFICATES.  If any Share Certificate(s)
    has been lost, destroyed or stolen, the shareholder should promptly notify
    the Transfer Agent for the Company. The shareholder will then be instructed
    as to the steps that must be taken in order to replace the Share
    Certificate(s). This Letter of Transmittal and related documents cannot be
    processed until the procedures for replacing lost or destroyed Share
    Certificates have been followed.

    IMPORTANT: THIS LETTER OF TRANSMITTAL (OR A FACSIMILE COPY THEREOF),
TOGETHER WITH ANY REQUIRED SIGNATURE GUARANTEES, OR, IN THE CASE OF A BOOK-ENTRY
TRANSFER, AN AGENT'S MESSAGE AND ANY OTHER REQUIRED DOCUMENTS MUST BE RECEIVED
BY THE DEPOSITARY ON OR PRIOR TO THE EXPIRATION DATE AND EITHER CERTIFICATES FOR
TENDERED SHARES MUST BE RECEIVED BY THE DEPOSITARY OR SHARES MUST BE DELIVERED
PURSUANT TO THE PROCEDURES FOR BOOK-ENTRY TRANSFER, IN EACH CASE PRIOR TO THE
EXPIRATION DATE, OR THE TENDERING SHAREHOLDER MUST COMPLY WITH THE PROCEDURES
FOR GUARANTEED DELIVERY.

OBTAINING A NUMBER

    If you do not have a taxpayer identification number or you do not know your
number, obtain Form SS-5, Application for a Social Security Number Card (for
resident individuals), Form SS-4, Application for Employer Identification Number
(for businesses and all other entities), or Form W-7 for International Taxpayer
Identification Number (for alien individuals required to file U.S. tax returns),
at an office of the Social Security Administration or the Internal Revenue
Service.

    To complete Substitute Form W-9, if you do not have a taxpayer
identification number, write "Applied For" in the space for the taxpayer
identification number in Part 1, sign and date the Form, and give it to the
requester. Generally, you will then have 60 days to obtain a taxpayer
identification number and furnish it to the requester. If the requester does not
receive your taxpayer identification number within 60 days, backup withholding,
if applicable, will begin and will continue until you furnish your taxpayer
identification number to the requester.

    - Payments made by certain foreign organizations.

    - Payments made to a nominee.

    Payments of interest not generally subject to backup withholding include the
following:

    - Payments of interest on obligations issued by individuals. NOTE: You may
      be subject to backup withholding if (i) this interest is $600 or more, and
      (ii) the interest is paid in the course of the payer's trade or business
      and (iii) you have not provided your correct taxpayer identification
      number to the payer.

    - Payments of tax-exempt interest (including exempt-interest dividends under
      section 852).

    - Payments described in section 6049(b)(5) to non-resident aliens.

    - Payments on tax-free covenant bonds under section 1451.

    - Payments made by certain foreign organizations.

    - Payments made to a nominee.

EXEMPT PAYEES DESCRIBED ABOVE SHOULD FILE A SUBSTITUTE FORM W-9 TO AVOID
POSSIBLE ERRONEOUS BACKUP WITHHOLDING. FILE THIS FORM WITH THE PAYER, FURNISH
YOUR TAXPAYER IDENTIFICATION NUMBER, WRITE "EXEMPT" ON THE FACE OF THE FORM, AND
RETURN IT TO THE PAYER.

    Certain payments other than interest, dividends, and patronage dividends
that are not subject to information reporting are also not subject to backup
withholding. For details, see the regulations under sections 6041, 6041A(a),
6045, and 6050A.

    PRIVACY ACT NOTICES. Section 6109 requires most Recipients of dividends,
interest, or other payments to give taxpayer identification numbers to payers
who must report the payments to the IRS. The IRS uses the numbers for
identification purposes and to help verify the accuracy of your tax return.
Payers must be given the numbers whether or not recipients are required to file
tax returns. Payers must generally withhold 31% of taxable interest, dividends,
and certain other payments to a payee who does not furnish a taxpayer
identification number to a payer. Certain penalties may also apply.

PENALTIES

    (1) PENALTY FOR FAILURE TO FURNISH TAXPAYER IDENTIFICATION NUMBER.--If you
fail to furnish your taxpayer identification number to a payer, you are subject
to a penalty of $50 for each such failure unless your failure is due to
reasonable cause and not to willful neglect.

    (2) FAILURE TO REPORT CERTAIN DIVIDEND AND INTEREST PAYMENTS.--If you fail
to include any portion of an includible payment for interest, dividends, or
patronage dividends in gross income and such failure is due to negligence, a
penalty of 20% is imposed on any portion of an underpayment attributable to the
failure.

                                       15
<PAGE>
    (3) CIVIL PENALTY FOR FALSE STATEMENTS WITH RESPECT TO WITHHOLDING.--If you
make a false statement with no reasonable basis which results in no imposition
of backup withholding, you are subject to a penalty of $500.

    (4) CRIMINAL PENALTY FOR FALSIFYING INFORMATION.--If you falsify
certifications or affirmations, you are subject to criminal penalties including
fines and/or imprisonment.

FOR ADDITIONAL INFORMATION CONTACT YOUR TAX CONSULTANT OR THE INTERNAL REVENUE
SERVICE.

To Our Clients:

    Enclosed for your consideration are the Offer to Purchase dated July 30,

pertaining to the offer by ABCI Acquisition Sub. Corporation (the "Purchaser"),
a Delaware corporation and a wholly owned subsidiary of Biovail Corporation
International, an Ontario, Canada corporation ("Parent"), to purchase up to
6,585,225 of the outstanding shares of Common Stock, par value $0.01 per share
(the "Shares"), of Fuisz Technologies Ltd., a Delaware corporation (the

without interest thereon, upon the terms and subject to the conditions set forth
in the Offer. The Offer is conditioned upon, among other things, there being
validly tendered and not withdrawn prior to the expiration date of the Offer
(the "Expiration Date") at least 4,602,460 Shares (the "Minimum Condition").
This material is being forwarded to you as the beneficial owner of Shares
carried by us in your account but not registered in your name.

    WE ARE THE HOLDER OF RECORD OF SHARES HELD BY US FOR YOUR ACCOUNT. A TENDER
OF SUCH SHARES CAN BE MADE ONLY BY US AS THE HOLDER OF RECORD AND PURSUANT TO
YOUR INSTRUCTIONS. THE LETTER OF TRANSMITTAL IS FURNISHED TO YOU FOR YOUR
INFORMATION ONLY AND CANNOT BE USED BY YOU TO TENDER SHARES HELD BY US FOR YOUR
ACCOUNT.

    Accordingly, we request instructions as to whether you wish to tender any or
all of the Shares held by us for your account, upon the terms and subject to the
conditions set forth in the Offer.

    Please note the following:

    1.  The tender offer price is $7.00 per Share, net to you in cash, without
       interest thereon.
<PAGE>
    2.  The Offer is being made for up to 6,585,225 of the outstanding Shares
       not currently owned directly or indirectly by Parent.

    3.  The Offer and withdrawal rights will expire at 12:00 midnight, New York
       City time, on Thursday, August 26, 1999, unless the Offer is extended.

    4.  The Offer is conditioned upon the Minimum Condition and (ii) the
       expiration of any waiting period under the Antitrust Laws (as defined in
       the Offer to Purchase: "The Tender Offer--14. Certain Conditions of the
       Offer") applicable to the purchase of Shares pursuant to the Offer and
       the Merger (as defined in the Offer to Purchase) (the "Antitrust
       Condition"). The Purchaser reserves the right, subject only to the
       applicable rules and regulations of the Securities and Exchange
       Commission (the "Commission"), to waive each of the conditions to the
       obligations of the Purchaser to consummate the offer to the extent
       permitted by law. The Offer is also subject to other terms and conditions
       contained in the Offer to Purchase.

    5.  Tendering stockholders will not be obligated to pay brokerage fees or
       commissions or, except as set forth in Instruction 6 of the Letter of
       Transmittal, stock transfer taxes on the transfer of Shares pursuant to
       the Offer.

    6.  The Company's Board of Directors has approved the Offer, the Merger (as
       defined in the Offer to Purchase) and the Merger Agreement (as defined in
       the Offer to Purchase) and determined that the terms of the Offer and the
       Merger are fair to and in the best interests of the Company's
       shareholders and recommends that the Company's shareholders accept the
       Offer and tender all of their Shares pursuant to the Offer.

    If you wish to have us tender any or all of your Shares, please so instruct
us by completing, executing, detaching and returning to us the instruction form
contained in this letter. An envelope in which to return your instructions to us
is enclosed. If you authorize tender of your Shares, all such Shares will be
tendered unless otherwise indicated in such instruction form. Please forward
your instructions to us as soon as possible to allow us ample time to tender
Shares on your behalf prior to the expiration of the Offer.

    The Offer is made solely by the Offer to Purchase and the Letter of
Transmittal and any amendments or supplements thereto. The Purchaser is not
aware of any state where the making of the Offer is prohibited by the
administrative or judicial action pursuant to any valid state statute. If the
Purchaser becomes aware of any valid state statute prohibiting the making of the
Offer or the acceptance of the Shares pursuant thereto, the Purchaser will make
a good faith effort to comply with such statute. If, after such good faith
effort, the Purchaser cannot comply with such statute, the Offer will not be
made to (nor will tenders be accepted from or on behalf of) the holders of
Shares in such state. In those jurisdictions where the securities, blue sky or
other laws require the Offer to be made by a licensed broker or dealer, the
Offer shall be deemed to be made on behalf of the Purchaser by Donaldson, Lufkin
& Jenrette Securities Corporation or one or more registered brokers or dealers
licensed under the laws of such jurisdiction.

Biovail Corporation International (ticker: BVF, exchange: The New York Stock
Exchange) News Release - Wednesday, July 28, 1999
- -----------------------------------------------------------------------------

BIOVAIL REPORTS RECORD 1999 SECOND QUARTER AND YEAR TO DATE FINANCIAL RESULTS

TORONTO--(BW HealthWire)--July 28, 1999--Biovail Corporation International
(NYSE:BVF) (TSE:BVF.) today reported record second quarter and six month
financial results for the period ended June 30, 1999.

Revenue for the second quarter and first half of 1999 increased by 43% and
37% respectively to $36.2 million and $64.4 million, compared to second
quarter 1998 revenue of $25.3 million and first half 1998 revenue of $47.1
million.

Operating income for the quarter was $15.5 million and for the first half of
1999 was $27.1 million, representing increases of 53% and 46% respectively
over the comparable periods of 1998.

Net income of $12.1 million or $0.49 per share was achieved in the quarter, a
26% increase over the net income of $9.5 million or $0.36 per share earned in
1998. For the first half of 1999, net income of $20.4 million or $0.83 per
share was achieved, a 17% increase over $17.4 million or $0.65 per share in
the comparable period of 1998.

Revenue and income improvements in both the second quarter and first half of
1999 are primarily attributable to increasing market penetration of
Tiazac-Registered Trademark-, Biovail's prescription drug used in the
treatment of angina and hypertension, in the United States and Canada. In
addition, the launch of a generic version of the angina/hypertension drug
Verelan in the United States and the Canadian launches of Retavase, a
fibrinolytic clot dissolving product, Brexidol, used for the relief of pain
and Celexa, an anti-depressant have all contributed to the company's
increasing revenue and income performance.

Eugene Melnyk, Chairman of the Board commented, "We are very pleased to
report that the strategic initiatives undertaken at Biovail historically are
today generating continually improving financial results. Our pipeline of
products is very strong and is expected to contribute significantly in the
near future. In addition, completion of the recently announced merger
agreement with Fuisz Technologies Ltd. will provide the combined operations
with leading edge drug delivery technology platforms that can be applied to a
wide array of important drugs. This acquisition provides Biovail greater
leverage to take advantage of the many exciting opportunities available to
the company."

Biovail Corporation International is an international full-service
pharmaceutical company, engaged in the formulation, clinical testing,
registration and manufacture of drug products utilizing advanced drug
delivery technologies.

                       BIOVAIL CORPORATION INTERNATIONAL

    THE OFFER, PRORATION PERIOD AND WITHDRAWAL RIGHTS WILL EXPIRE AT 12:00
 MIDNIGHT, NEW YORK CITY TIME, ON THURSDAY, AUGUST 26, 1999, UNLESS THE OFFER
                                  IS EXTENDED.

     ABCI Acquisition Sub. Corporation, a Delaware corporation (the
"Purchaser") and a wholly-owned subsidiary of Biovail Corporation
International, an Ontario, Canada corporation ("Parent"), is offering to
purchase up to 6,585,225 of the outstanding shares of common stock, par value
$0.01 per share (the "Shares"), of Fuisz Technologies Ltd., a Delaware
corporation (the "Company"), at a purchase price of $7.00 per Share, net to
the seller in cash, without interest thereon (the "Offer Price"), upon the
terms and subject to the conditions set forth in the Offer to Purchase, dated
July 30, 1999 (the "Offer to Purchase"), and in the related Letter of
Transmittal (which together with any amendments or supplements thereto,
collectively constitute the "Offer").

     The Offer is conditioned upon, among other things, (1) there being
validly tendered and not withdrawn prior to the expiration date of the Offer
(the "Expiration Date") at least 4,602,460 Shares (the "Minimum Condition")
and (2) the expiration of any waiting period under the Antitrust Laws (as
defined in the Offer to Purchase) applicable to the purchase of the Shares
pursuant to the Offer and the Merger (the "Antitrust Condition"). The
Purchaser reserves the right, subject only to the applicable rules and
regulations of the Securities and Exchange Commission, to waive each of the
conditions to the obligations of the Purchaser to consummate the Offer to the
extent permitted by law. The intention of Parent is to acquire 100% of the
Company pursuant to the Offer and the merger described below.

     The Offer is being made pursuant to an Agreement and Plan of Merger,
dated July 25, 1999, (the "Merger Agreement") by and among Parent, Purchaser
and the Company. The Merger Agreement provides, among other things, for the
commencement of the Offer by the Purchaser and further provides that, after
the purchase of Shares pursuant to the Offer and subject to the satisfaction
or waiver of certain conditions set forth therein, the Purchaser will be
merged with and into the Company (the "Merger"), with the Company surviving
the Merger as a wholly-owned subsidiary of Parent.

     In the Merger, each Share issued and outstanding immediately prior to
the effective time of the Merger (other than Shares, if any, held in the
treasury of the Company, held by the Purchaser and held by Parent or any
direct or indirect wholly-owned subsidiary of Parent) will be converted into
the right to receive a fraction of a common share, no par value, of Parent
(the "Parent Common Stock") based on an exchange ratio (the "Exchange Ratio")
determined as follows: (i) if the average of the daily closing price per
share of Parent Common Stock on the New York Stock Exchange ("NYSE")
Composite Transactions Reporting System, as reported in The Wall Street
Journal for the fifteen trading days ending on the date immediately prior to
the second full NYSE trading day immediately preceding the closing date of
the Merger (the "Average Trading Price"), is less than $45.00, the Exchange
Ratio shall equal .1556; (ii) if the Average Trading Price is greater than or
equal to $45.00, but less than or equal to $58.625, the Exchange Ratio shall
equal a fraction (rounded to the nearest ten-thousandth) determined by
dividing $7.00 by the Average Trading Price; (iii) if the Average Trading
Price is greater than $58.625 but less than or equal to $62.810, the Exchange
Ratio shall equal .1194 and (iv) if the Average Trading Price is greater than
$62.810, the Exchange Ratio shall equal a fraction (rounded to the nearest
ten-thousandth) determined by dividing $7.50 by the Average Trading Price
subject to adjustment as provided in the Merger Agreement.

     THE SPECIAL COMMITTEE AND THE BOARD OF DIRECTORS OF THE COMPANY HAVE
APPROVED THE OFFER, THE MERGER AND THE MERGER AGREEMENT AND DETERMINED THAT
THE TERMS OF THE OFFER AND THE MERGER ARE FAIR TO AND IN THE BEST INTERESTS
OF THE COMPANY'S SHAREHOLDERS, AND RECOMMEND THAT THE COMPANY'S SHAREHOLDERS
ACCEPT THE OFFER AND TENDER ALL OF THEIR SHARES PURSUANT TO THE OFFER.

     For purposes of the Offer, the Purchaser will be deemed to have accepted
for payment, and thereby purchased, tendered Shares if, as and when the
Purchaser gives oral or written notice to ChaseMellon Shareholder Services,
L.L.C. (the "Depositary") of the Purchaser's acceptance of such Shares for
payment. Payment for Shares accepted pursuant to the Offer will be made by
deposit of the aggregate purchase price therefor with the Depositary, which
will act as agent for tendering shareholders for the purpose of receiving
payment from the Purchaser and transmitting payment to such tendering
shareholders. Under no circumstances will interest on the Offer Price for
Shares be paid by the Purchaser by reason of any delay in making such payment.

     In all cases, payment for Shares tendered and accepted for payment
pursuant to the Offer will be made only after timely receipt by the
Depositary of (i) the certificate(s) representing tendered Shares (the "Share
Certificates") with timely confirmation of a book-entry transfer of such
Shares (if such procedure is available) into the Depositary's account at The
Depository Trust Company (the "Book-Entry Transfer Facility") pursuant to the
procedures set forth in section 3 of the Offer to Purchase, (ii) the Letter
of Transmittal (or a facsimile thereof), properly completed and duly
executed, or an Agent's Message (as defined in the Offer to Purchase) in
connection with a book-entry transfer, and (iii) any other documents required
by the Letter of Transmittal. If any tendered Shares are not accepted for
payment for any reason pursuant to the terms and conditions of the Offer
(including due to proration if more than the maximum number of Shares of the
Company are tendered) or if Share Certificates are submitted evidencing more
Shares than are tendered, Share Certificates evidencing unaccepted or
unpurchased Shares will be returned, without expense to the tendering
shareholder (or, in the case of Shares tendered by book-entry transfer into
the Depositary's account at the Book-Entry Transfer Facility pursuant to the
procedure set forth in Section 3 of the Offer to Purchase, such Shares will
be credited to an account maintained at the Book-Entry Transfer Facility), as
promptly as practicable following the expiration or termination of the Offer.

     Except as otherwise provided in the Offer to Purchase, tenders of Shares
made pursuant to the Offer are irrevocable. Shares tendered pursuant to the
Offer may be withdrawn at any time prior to the Expiration Date and, unless
previously accepted for payment by the Purchaser pursuant to the Offer, may
also be withdrawn at any time after September 27, 1999. For a withdrawal to
be effective, a written or facsimile transmission notice of withdrawal must
be timely received by the Depositary at one of its addresses set forth in the
Offer to Purchase. Any such notice of withdrawal must specify the name of the
person who tendered the Shares to be withdrawn, the number of Shares to be
withdrawn and (if Share Certificates have been tendered) the name of the
registered holder, if different from that of the person who tendered such
Shares. If Share Certificates evidencing Shares to be withdrawn have been
delivered or otherwise identified to the Depositary, then, prior to the
release of such Share Certificates, the serial numbers shown on the
particular Share Certificates to be withdrawn must be submitted to the
Depositary, and the signature(s) on the notice of withdrawal must be
guaranteed by an Eligible Institution (as defined in the Offer to Purchase),
unless such Shares have been tendered for the account of an Eligible
Institution. If Shares have been tendered pursuant to the procedure for
book-entry transfer as set forth in Section 3 of the Offer to Purchase, any
notice of withdrawal must also specify the name and number of the account at
the Book-Entry Transfer Facility to be credited with the withdrawn Shares, in
which case a notice of withdrawal will be effective if delivered to the
Depositary by any method of delivery described in Section 3 of the Offer to
Purchase. Withdrawals of Shares may not be rescinded. Withdrawn Shares may be
retendered at any time prior to the Expiration Date by following one of the
procedures described in Section 3 of the Offer to Purchase. All questions as
to the form and validity (including, without limitation, time of receipt) of
notices of withdrawal will be determined by the Purchaser, in its sole
discretion, which determination will be final and binding.

     The Purchaser may amend the Offer, from time to time in accordance with
the terms of the Merger Agreement to extend the period of time during which
the Offer is open by giving oral or written notice of such extension to the
Depositary. Any such extension will be followed as promptly as practicable by
public announcement thereof no later than 9:00 a.m., New York City time, on
the next business day after the previously scheduled date on which the Offer
was to expire. During any such extension, all Shares previously tendered and
not withdrawn will remain subject to the Offer, subject to the right of a
tendering shareholder to withdraw such shareholder's Shares.

     THE OFFER DOES NOT CONSTITUTE A SOLICITATION OF PROXIES FOR ANY MEETING
OF THE SHAREHOLDERS OF THE COMPANY OR ANY OFFER TO SELL OR SOLICITATION OF
OFFERS TO BUY PARENT COMMON STOCK OR OTHER SECURITIES. ANY SUCH SOLICITATION
WILL BE MADE ONLY PURSUANT TO SEPARATE PROXY MATERIALS PURSUANT TO THE
REQUIREMENTS OF SECTION 14(A) OF THE SECURITIES EXCHANGE ACT OF 1934, AS
AMENDED (THE "EXCHANGE ACT") AND ANY SUCH OFFER WILL BE MADE ONLY THROUGH A
REGISTRATION STATEMENT AND PROSPECTUS PURSUANT TO THE REQUIREMENTS OF THE
SECURITIES ACT OF 1933, AS AMENDED, WHICH PROSPECTUS WILL ALSO CONSTITUTE A
PROXY STATEMENT FOR THE MEETING OF THE SHAREHOLDERS OF THE COMPANY RELATING
TO THE MERGER.

     The information required to be disclosed by paragraph (e)(1)(vii) of
Rule 14d-6 of the General Rules and Regulations under the Exchange Act, is
contained in the Offer to Purchase and is incorporated herein by reference.

     The Company has provided the Purchaser with the Company's shareholder
list and security position listings for the purpose of disseminating the
Offer to holders of Shares. The Offer to Purchase, the related Letter of
Transmittal and, if required, any other relevant materials will be mailed to
record holders of Shares and will be furnished to brokers, dealers,
commercial banks, trust companies and similar persons whose names, or the
names of whose nominees, appear on the shareholder list or, if applicable,
who are listed as participants in a clearing agency's security position
listing for subsequent transmittal to beneficial owners of Shares by
Purchaser.

     THE OFFER TO PURCHASE AND THE RELATED LETTER OF TRANSMITTAL CONTAIN
IMPORTANT INFORMATION WHICH SHOULD BE READ CAREFULLY BEFORE ANY DECISION IS
MADE WITH RESPECT TO THE OFFER.

     Requests for copies of the Offer to Purchase, the Letter of Transmittal
and other tender offer materials may be directed to the Information Agent or
the Dealer Manager as set forth below and copies will be furnished promptly
at the Purchaser's expense. Questions or requests for assistance may be

Purchaser nor the Parent will pay any fees or commissions to any broker or
dealer or any other person (other than the Dealer Manager, the Depositary and
the Information Agent) in connection with the solicitation of tenders of
Shares pursuant to the Offer.

                     The Information Agent for the Offer is:

Shares" or "Shares"), as will cause Parent and its affiliates to beneficially
own up to 49% of the outstanding Common Shares, but, except as otherwise
provided herein, not less than 40% of the outstanding Common Shares, at a price
per Common Share of $7.00 net to the seller in cash (such price, as it may

<PAGE>

each issued and outstanding Share not owned directly or indirectly by Parent
or the Company will be converted into the right to receive the number of
shares of the common stock of Parent (the "Parent Common Stock") as described
on Annex II (the "Merger Consideration");

                  WHEREAS, Parent, the Purchaser and the Company desire to make
certain representations, warranties, covenants and agreements in connection with
the Offer and the Merger and also to prescribe various conditions to the Offer
and the Merger.

                  NOW, THEREFORE, in consideration of the foregoing and the
respective representations, warranties, covenants and agreements set forth
herein, Parent, the Purchaser and the Company agree as follows:


                                    ARTICLE I

                                    THE OFFER


                  SECTION 1.01.     THE OFFER.

                  (a) So long as none of the events set forth in clauses (a)
through (f) of Annex I hereto (the "conditions to the Offer") shall have
occurred or exist, the Purchaser shall, and Parent shall cause the Purchaser to,
commence (within the meaning of Rule 14d-2(a) of the Securities Exchange Act of
1934, as amended (the "Exchange Act")) as promptly as practicable after the date
hereof, but in any event not later than July 30, 1999, the Offer for such number
of Shares as will cause Parent and its affiliates to beneficially own up to 49%,
but except as otherwise provided herein, not less than 40%, of the outstanding
Shares (with such Shares to be purchased on a PRO RATA basis among Shares
validly tendered and not withdrawn), at the Offer Price, net to the seller in
cash. The initial expiration date for the Offer shall be the twentieth business
day from and after the date the Offer is commenced, including the date of
commencement as the first business day in accordance with Rule 14d-2 under the
Exchange Act. As promptly as practicable, the Purchaser shall file with the
Securities and Exchange Commission (the "SEC" or the "Commission") the
Purchaser's Tender Offer Statement on Schedule 14D-1 (together with any
supplements or amendments thereto, the "Offer Documents"), which shall contain
(as an exhibit thereto) the Purchaser's Offer to Purchase (the "Offer to
Purchase") which shall be mailed to the holders of Shares with respect to the


                                      -2-

<PAGE>

Offer. The obligation of the Purchaser to accept for payment or pay for any
Shares tendered pursuant to the Offer will be subject only to the satisfaction
or waiver of the conditions to the Offer set forth on Annex I. Without the prior
written consent of the Company, the Purchaser shall not decrease the price per
Share, waive the Minimum Condition, or change the form of consideration payable
in the Offer, decrease the number of Shares sought to be purchased in the Offer,
change the conditions to the Offer, impose additional conditions to the Offer or
amend any other term of the Offer in any manner adverse to the holders of
Shares; PROVIDED, HOWEVER, that Parent shall be required to extend the Offer
from time to time to the extent any conditions to the Offer reasonably capable
of being satisfied have not been satisfied on the applicable expiration date but
not beyond the 55th business day from and including the business day the Offer
commences. Any such extension shall not be for a period greater than the period
of time Parent reasonably expects to be necessary to satisfy such conditions.
Subject to the terms of the Offer and this Agreement and the satisfaction or
waiver of all the conditions of the Offer as of any expiration date, Parent will
accept for payment and pay for Shares validly tendered and not withdrawn
pursuant to the Offer as soon as practicable after such expiration date of the
Offer (the "Tender Offer Effective Date").

                  (b) The Offer Documents will comply in all material respects
with the provisions of applicable federal securities laws and, on the date filed
with the SEC and on the date first published, sent or given to the Shareholders,
shall not contain any untrue statement of a material fact or omit to state any
material fact required to be stated therein or necessary in order to make the
statements made therein, in light of the circumstances under which they were
made, not misleading, except that no representation is made by Parent or the
Purchaser with respect to information supplied by or on behalf of the Company in
writing for inclusion in the Offer Documents. Each of Parent and the Purchaser,
on the one hand, and the Company, on the other hand, agrees promptly to correct
any information provided by or on behalf of it for use in the Offer Documents if
and to the extent that it shall have become false or misleading in any material
respect, and the Purchaser further agrees to take all steps necessary to cause
the Offer Documents as so corrected to be filed with the SEC and to be
disseminated to Shareholders, in each case as and to the extent required by
applicable federal securities laws.

                  (a) Contemporaneously with the filing of the Offer Documents,
the Company shall file with the SEC and shall promptly mail to the Shareholders
a Solicitation/Recommendation Statement on Schedule 14D-9 with respect to the
Offer (together with any amendments or supplements thereto, the "Schedule
14D-9"). The Schedule 14D-9 will set forth, and the Company hereby represents,
that the Board of Directors of the Company, at a meeting duly called and held on
July 6, 1999 has approved the Stock Option Agreement in accordance with Section
203 of the GCL. The Schedule 14D-9 will set forth, and the Company hereby
represents, that the Board of Directors of the Company, at a meeting duly called
and held on July 25, 1999 (the "Company Board Meeting"), has (i) determined that
the Offer and the Merger are fair to and in the best interests of the Company
and its Shareholders, (ii) approved the Offer and the Merger in accordance with
Section 203 of the GCL (and for purposes of any other applicable state takeover
law), and (iii) resolved to recommend acceptance of the Offer and approval and
adoption of the Merger and this Agreement by the Company's Shareholders (in
accordance with the requirements of the Company's Amended and Restated
Certificate of Incorporation and of applicable law); PROVIDED, HOWEVER, that,
subject to Section 8.02(c), such recommendation may be withdrawn, modified or
amended to the extent that the Board of Directors of the Company determines
reasonably and in good faith that it is necessary under applicable law to do so
in the exercise of its fiduciary obligations after consultation with outside
counsel; PROVIDED, FURTHER, HOWEVER, that notwithstanding any withdrawal,
modification or amendment of such recommendation, the Company agrees that if the
Purchaser purchases Shares pursuant to the Offer, this Agreement shall be
submitted to the Shareholders for approval and adoption at the Special Meeting
whether or not the Board of Directors determines at any time subsequent to the
Company Board Meeting that this Agreement is no longer advisable and recommends
that Shareholders reject it.

                  (b) The Schedule 14D-9 will comply in all material respects
with the provisions of applicable federal securities laws and, on the date filed
with the SEC and on the date first published, sent or given to the Shareholders,
shall not contain any untrue statement of a material fact or omit to state any
material fact required to be stated therein or necessary in order to make the
statements made therein, in light of the circumstances under which they were
made, not misleading, except that no representation is made by the Company with
respect to information supplied by or on behalf of the Parent or Purchaser


                                      -4-

in writing for inclusion in the Schedule 14D-9. Each of the Company, on the
one hand, and Parent and the Purchaser, on the other hand, agrees promptly to
correct any information provided by either of them for use in the Schedule
14D-9 if and to the extent that it shall have become false or misleading in
any material respect, and the Company further agrees to take all steps
necessary to cause the Schedule 14D-9 as so corrected to be filed with the
SEC and to be disseminated to the Shareholders, in each case as and to the
extent required by applicable federal securities law.

                  (c) In connection with the Offer, the Company will promptly
furnish the Purchaser with such information and assistance as the Purchaser or
its agents or representatives may reasonably request in connection with
communicating the Offer to the record and beneficial holders of the Securities,
including, without limitation, its stockholders list, mailing labels, security
position listings and non-objecting beneficial owners list. The Purchaser will
keep such information confidential and not use it for any other purpose.

                  SECTION 1.03.     DIRECTORS.

                  (a) Subject to compliance with applicable law, promptly upon
the payment by the Purchaser or Parent, as the case may be, for Shares pursuant
to the Offer, and from time to time thereafter, Parent shall be entitled to
designate such number of directors, rounded up to the next whole number, on the
Board of Directors of the Company as is equal to the product of the total number
of directors on the Board of Directors of the Company (determined after giving
effect to the directors elected pursuant to this sentence) multiplied by the
percentage that the aggregate number of Shares beneficially owned by Parent or
its affiliates bears to the total number of Shares then outstanding, and the
Company shall, upon request of Parent, promptly take all actions necessary to
cause Parent's designees to be so elected, including, if necessary, seeking the
resignations of one or more existing directors; PROVIDED, HOWEVER, that prior to
the Effective Time (as defined in Section 2.02), the members of the Board which
are officers, directors or designees of the Parent ("Purchaser Insiders") shall
at all times be less than 50% of the total number of Board members.

                  (b) From and after the election or appointment of Parent's
designees pursuant to this Section 1.03 and prior to the Effective Time, any
amendment or termination of this Agreement by the Company, any extension by the
Company of the time for the performance of any of the obligations or other acts
of


                                      -5-
<PAGE>

Parent or the Purchaser or waiver of any of the Company's rights hereunder,
or any other action taken by the Board of Directors of the Company in connection
with this Agreement, will require the concurrence of a majority of the directors
of the Company then in office who are not Purchaser Insiders.

                  (c) Promptly upon the payment by the Purchaser or Parent, as
the case may be, for Shares pursuant to the Offer, Parent shall be entitled to
designate one officer of the Company (reasonably acceptable to the Company) to
address such matters of contract negotiation and administration as Parent shall
reasonably request and the Board of Directors of the Company, acting reasonably,
shall approve. Such officer shall work together with other business development
officers at the Company with comparable duties and responsibilities, and shall
be subject to the same currently existing reporting and procedural limitations
as such other officers. Such officer shall report to and serve at the pleasure
of the Board of Directors of the Company; PROVIDED, that such officer shall not
be terminated without the approval of at least two-thirds of the members of the
Board of Directors (including Purchaser Insiders).

                               EXCHANGE PROVISIONS


                  SECTION 3.01. EXCHANGE PROVISIONS.

                  (a) EXCHANGE AGENT. From and after the Effective Time, (i)
Parent shall make available to a bank or trust company designated by Parent
subject to the Company's consent, which shall not be unreasonably withheld (the
"Exchange Agent"), for the benefit of the holders of shares of Company Common
Stock, for exchange in accordance with this Section through the Exchange Agent,
certificates evidencing a sufficient number of shares of Parent Common Stock as
would permit the Exchange Agent to issue such number of shares of Parent Common
Stock issuable to holders of Company Common Stock pursuant to Section 2.07 (such
certificates for Parent Common Stock, together with any dividends or
distributions with respect thereto, being hereinafter referred to as the
"Exchange Fund"). As promptly as practicable after the Effective Time, Parent
shall cause the Exchange Agent to deliver the Parent Common Stock contemplated
to be issued pursuant to Section 2.07 out of the Exchange Fund in accordance
with the procedures specified in this Section 3.01. Except as contemplated by
Section


                                      -9-

<PAGE>

3.01(g) hereof, the Exchange Fund shall not be used for any other purpose.

                  (b) EXCHANGE PROCEDURES. As promptly as practicable after the
Effective Time, Parent shall cause the Exchange Agent to mail to each record
holder of a certificate or certificates which immediately prior to the Effective
Time represented outstanding shares of Company Common Stock (the "Certificates")
(i) a letter of transmittal (which shall be in customary form and shall specify
that delivery shall be effected, and risk of loss and title to the Certificates
shall pass, only upon proper delivery of the Certificates to the Exchange Agent)
and (ii) instructions for use in effecting the surrender of the Certificates in
exchange for the Merger Consideration.

                  (c) EXCHANGE OF CERTIFICATES. Upon surrender to the Exchange
Agent of a Certificate for cancellation, together with such letter of
transmittal, duly executed and completed in accordance with the instructions
thereto, and such other documents as may be reasonably required pursuant to such
instructions, the holder of such Certificate shall be entitled to receive in
exchange therefor a certificate representing that number of whole shares of
Parent Common Stock, if any, to which such holder is entitled pursuant to this
Section 3.01 (including any cash in lieu of any fractional Parent Common Stock
to which such holder is entitled pursuant to Section 3.01(f) and any dividends
or other distributions to which such holder is entitled pursuant to Section
3.01(d) (together, the "Additional Payments")), and the Certificate so
surrendered shall forthwith be canceled. In the event of a transfer of ownership
of shares of Company Common Stock which is not registered in the transfer
records of the Company, the applicable Merger Consideration and Additional
Payments, if any, may be issued to a transferee if the Certificate representing
such shares of Company Common Stock is presented to the Exchange Agent,
accompanied by all documents required to evidence and effect such transfer and
by evidence that any applicable stock transfer taxes have been paid. Until
surrendered as contemplated by this Section 3.01, each Certificate shall be
deemed at all times after the Effective Time to represent only the right to
receive upon such surrender the applicable Merger Consideration with respect to
the shares of Company Common Stock formerly represented thereby and Additional
Payments, if any.

                  (d) DISTRIBUTIONS WITH RESPECT TO UNSURRENDERED CERTIFICATES.
No dividends or other distributions declared or made after the Effective Time
with respect to Parent Common Stock with a record date after the Effective Time
shall be paid


                                      -10-

<PAGE>

to the holder of any unsurrendered Certificate with respect to the Parent
Common Stock the holder of such Certificate is entitled to receive upon
surrender thereof, and no cash payment in lieu of any fractional shares shall
be paid to any such holder pursuant to Section 3.01(f), until the holder of
such Certificate shall surrender such Certificate. Subject to the effect of
escheat, tax or other applicable Laws, following surrender of any such
Certificate, there shall be paid to the holder of the certificates
representing whole shares of Parent Common Stock issued in exchange therefor,
without interest, (i) promptly, the amount of any cash payable with respect
to a fractional Parent Common Stock to which such holder is entitled pursuant
to Section 3.01(f) and the amount of dividends or other distributions with a
record date after the Effective Time and theretofore paid with respect to
such whole shares of Parent Common Stock, and (ii) at the appropriate payment
date, the amount of dividends or other distributions, with a record date
after the Effective Time but prior to surrender and a payment date occurring
after surrender, payable with respect to such whole Parent Common Stock.
After the Effective Time, each outstanding Certificate which theretofore
represented shares of Company Common Stock shall, until surrendered for
exchange in accordance with this Section 3.01, be deemed for all purposes to
evidence ownership of the number of shares of Parent Common Stock into which
the shares of Company Common Stock (which, prior to the Effective Time, were
represented thereby) shall have been so converted.

                  (e) NO FURTHER RIGHTS IN COMPANY COMMON STOCK. At the
Effective Time all outstanding shares of Company Common Stock, by virtue of the
Merger and without any action on the part of the holders thereof, shall no
longer be outstanding and shall be canceled and retired and shall cease to
exist, and each holder of a certificate representing any such shares of Company
Common Stock shall thereafter cease to have any rights with respect to such
shares of Company Common Stock, except the right to receive the Merger
Consideration for such shares of Company Common Stock. All Parent Common Stock
issued upon conversion of the shares of Company Common Stock in accordance with
the terms hereof (including any cash paid pursuant to Section 3.01(d) or (f))
shall be deemed to have been issued in full satisfaction of all rights
pertaining to such shares of Company Common Stock.

                  (f) NO FRACTIONAL SHARES. No certificates or scrip
representing fractional shares of Parent Common Stock shall be issued upon the
surrender for exchange of Certificates, and such fractional share interests will
not entitle the owner


                                      -11-

<PAGE>

thereof to vote or to any other rights of a holder of Parent Common Stock.
Each holder of a fractional share interest shall be paid an amount in cash
equal to the product obtained by multiplying (i) such fractional share
interest to which such holder (after taking into account all fractional share
interests then held by such holder) would otherwise be entitled by (ii) the
Average Trading Price (as defined on Annex II). As promptly as practicable
after the determination of the amount of cash, if any, to be paid to holders
of fractional share interests, the Exchange Agent shall so notify Parent, and
Parent shall deposit such amount with the Exchange Agent and shall cause the
Exchange Agent to forward payments to such holders of fractional share
interests subject to and in accordance with the terms of Sections 3.01(b),
(c) and (d).

                  (g) TERMINATION OF EXCHANGE FUND. Any portion of the Exchange
Fund which remains undistributed to the holders of Company Common Stock for
three months after the Effective Time shall be delivered to Parent, upon demand,
and any holders of Company Common Stock who have not theretofore complied with
this Article III shall thereafter look only to Parent for the applicable Merger
Consideration and any Additional Payments to which they are entitled. Any
portion of the Exchange Fund remaining unclaimed by holders of shares of Company
Common Stock as of a date which is immediately prior to such time as such
amounts would otherwise escheat to or become property of any government entity
shall, to the extent permitted by applicable Law, become the property of Parent
free and clear of any claims or interest of any person previously entitled
thereto.

                  (h) NO LIABILITY. None of the Exchange Agent, Parent or the
Surviving Corporation shall be liable to any holder of Certificates for any
shares of Parent Common Stock (or dividends or distributions with respect
thereto), or cash delivered to a public official pursuant to any abandoned
property, escheat or similar law.

                  (i) WITHHOLDING RIGHTS. Each of the Surviving Corporation and
Parent shall be entitled to deduct and withhold from the consideration otherwise
payable pursuant to this Agreement to any holder of Certificates such amounts as
it is required to deduct and withhold with respect to the making of such payment
under the Code, or any provision of state, local or foreign tax law. To the
extent that amounts are so withheld by the Surviving Corporation or Parent, as

                                   ARTICLE IV

                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY


                  The Company represents and warrants to Parent and the
Purchaser that except as set forth in the section or subsection of the Company
Disclosure Statement corresponding to the section or subsection of this Article
IV delivered to Parent and the Purchaser prior to the execution hereof (the
"Company Disclosure Statement"):

                  SECTION 4.01. ORGANIZATION AND QUALIFICATION; SUBSIDIARIES.
The Company is a corporation duly organized, validly existing and in good
standing under the laws of the State of Delaware. Each subsidiary (as defined in
Section 10.09) of the Company (the "Subsidiaries") is a corporation duly
organized, validly existing and in good standing under the laws of the
jurisdiction of its incorporation. The Company and each of the Subsidiaries has
the requisite corporate power and authority to own, operate or lease its
properties and to carry on its business as it is now being conducted, and is
duly qualified or licensed to do business, and is in good standing, in each
jurisdiction in which the nature of its business or the properties owned,
operated or leased by it makes such qualification, licensing or good standing
necessary, except where the failures to have such power or authority, or the
failures to be so qualified, licensed or in good standing, individually, and in
the aggregate, would not have a Material Adverse Effect on the Company (as
defined below). The Company does not directly or indirectly own any equity or
similar interest in, or any interest convertible into or exchangeable or
exercisable for any equity or similar interest in, any corporation (other than a
Subsidiary), partnership, joint venture or other business association or entity.
The term "Material Adverse Effect on the Company" means any change in, or effect
on, the business, results of operations, assets, financial condition or
prospects of the Company or any of the Subsidiaries that is or would reasonably
be expected to be materially adverse to the Company and the Subsidiaries taken
as a whole.

                  SECTION 4.02.     AUTHORITY RELATIVE TO THIS AGREEMENT.


                                      -14-

<PAGE>

                  (a) The Company has all necessary corporate power and
authority to execute and deliver this Agreement and to consummate the
transactions contemplated hereby. The execution and delivery of this Agreement
by the Company and the consummation by the Company of the transactions
contemplated hereby and thereby have been duly and validly authorized and
approved by the Board of Directors of the Company and no other corporate
proceedings on the part of the Company are necessary to authorize or approve
this Agreement or to consummate the transactions contemplated hereby or thereby
(other than, with respect to the Merger, the approval and adoption of the Merger
and this Agreement by holders of a majority of the outstanding Shares to the
extent required by the Company's Amended and Restated Certificate of
Incorporation and by applicable law). This Agreement has been duly and validly
executed and delivered by the Company and, assuming the due and valid
authorization, execution and delivery of this Agreement by Parent and the
Purchaser, constitutes a valid and binding obligation of the Company enforceable
against the Company in accordance with its terms, except that such
enforceability (i) may be limited by bankruptcy, insolvency, moratorium or other
similar laws affecting or relating to the enforcement of creditors' rights
generally (the "Bankruptcy Exceptions") and (ii) is subject to general
principles of equity. The Board of Directors of the Company has, at the Company
Board Meeting approved and adopted this Agreement, the Offer, the Merger and the
other transactions contemplated hereby and thereby, determined that the Offer
and the Merger is fair to the Shareholders, recommended that the Shareholders
approve and adopt this Agreement, the Merger and tender their Shares pursuant to
the Offer and approved the submission of this Agreement to the Shareholders at
the Special Meeting if the Purchaser purchases Shares pursuant to the Offer
whether or not the Board of Directors of the Company determines at any time
subsequent to the Company Board Meeting that this Agreement is no longer
advisable and recommends that Shareholders reject it.

                  (b) To the knowledge of the Company as of the date of this
Agreement, all of its directors and executive officers intend to tender their
Shares pursuant to the Offer.

                  SECTION 4.03. NO CONFLICT; REQUIRED FILINGS AND CONSENTS.

                  (a) None of the execution and delivery of this Agreement by
the Company, the consummation by the Company of the transactions contemplated
hereby or thereby or compliance by the Company with any of the provisions hereof
or thereof


                                      -15-

will require any consent, waiver, approval, authorization or permit of, or
registration or filing with or notification to (any of the foregoing being a
"Consent"), any government, subdivision thereof, or any administrative,
governmental, regulatory or self-regulatory authority, agency, commission,
tribunal or body, domestic, foreign or supranational (a "Governmental
Entity") or person who is not a Governmental Entity, except for (i)

business in other jurisdictions, (ii) the filing of a certificate of merger
pursuant to the GCL and (iii) compliance with the Hart-Scott-Rodino Antitrust
Improvements Act of 1976, as amended (the "HSR Act").

                  (b) Except as set forth in clause (a) of this Section 4.03,
none of the execution and delivery of this Agreement by the Company, the
consummation by the Company of the transactions contemplated hereby and thereby
or compliance by the Company with any of the provisions hereof or thereof
will (i) conflict with or violate the Amended and Restated Certificate of
Incorporation or bylaws of the Company or the comparable organizational
documents of any of the Subsidiaries, (ii) conflict with or violate any
statute, ordinance, rule, regulation, order, judgment or decree applicable to
the Company or the Subsidiaries, or by which any of them or any of their
respective properties or assets may be bound or affected, or (iii) result in
a violation or breach of or constitute a default (or an event which with
notice or lapse of time or both would become a default) under, or give to
others any rights of termination, amendment, acceleration or cancellation of,
or result in any loss of any material benefit or the creation of any Lien (as
defined) on any of the property or assets of the Company or any of the
Subsidiaries (any of the foregoing referred to in clause (ii) or this clause
(iii) being a "Violation") pursuant to, any note, bond, mortgage, indenture,
contract, agreement, lease, license, permit, franchise or other instrument or
obligation to which the Company or any of the Subsidiaries is a party or by
which the Company or any of the Subsidiaries or any of their respective
properties may be bound or affected, except, in the case of clause (ii) and
(iii), for any such Violation which would not, individually or in the
aggregate, have a Material Adverse Effect on the Company.

                  SECTION 4.04. CERTAIN APPROVALS. The Board of Directors of the
Company has taken appropriate action such that the provisions of Section 203 of
the GCL will not apply to the


                                      -16-

<PAGE>

Offer, the Merger or any of the other transactions contemplated by this
Agreement or the Stock Option Agreement.

                  SECTION 4.05. OPINION OF FINANCIAL ADVISOR. The Board of
Directors of the Company has received the opinion of Warburg Dillon Read LLC to
the effect that, as of the date of this Agreement, the consideration to be
received in the Offer and the Merger, taken together, by the holders of Company
Common Stock (other than Parent and its affiliates) is fair, from a financial
point of view, to such holders.

                  SECTION 4.06. BROKERS. Except for the engagement of Warburg
Dillon Read LLC (a copy of whose engagement letter previously has been delivered
by the Company to Parent), none of the Company, any of the Subsidiaries or any
of their respective officers, directors or employees has employed any broker or
finder or incurred any liability for any brokerage fees, commissions or finder's
fees in connection with the transactions contemplated by this Agreement.

                  SECTION 4.07. CAPITALIZATION. The Company has heretofore made
available to Parent and the Purchaser a complete and correct copy of the Amended
and Restated Certificate of Incorporation and the by-laws, each as amended to
the date hereof, of the Company. The authorized capital stock of the Company
consists of 50,000,000 Common Shares and 2,323,356 shares of Preferred Stock,
par value $.01 per share (the "Preferred Stock"). Except as set forth on the
Company Disclosure Statement, as of the close of business on the day prior to
execution of this Agreement, there were no shares of Preferred Stock issued and
outstanding. As of the close of business on the day prior to execution of this
Agreement, there were 22,668,923 Common Shares issued, of which 638,200 were
owned by the Company or a wholly-owned Subsidiary. The Company has no shares of
capital stock reserved for issuance, except that, as of the day prior to
execution of this Agreement, there were 3,432,625 Common Shares reserved for
issuance pursuant to Options outstanding on the date hereof pursuant to the
Option Plans and 5,660,337 Common Shares reserved for issuance pursuant to the
Company's 7% Convertible Subordinated Debentures due 2004 (the "Convertible
Debentures"). Since the day prior to execution of this Agreement, the Company
has not issued any Options or shares of capital stock except pursuant to the
exercise of Options outstanding as of such date and in accordance with their
terms. All the outstanding Common Shares are, and all Common Shares which may be
issued pursuant to the exercise of outstanding Options will be, when issued in
accordance with the respective terms thereof, duly authorized, validly issued,


                                     -17-

<PAGE>

fully paid and nonassessable. Except for the Convertible Debentures, there are
no bonds, debentures, notes or other indebtedness having general voting rights
(or convertible into securities having such rights) ("Voting Debt") of the
Company or any of the Subsidiaries issued and outstanding. Except for the
Options, the Convertible Debentures and the warrants set forth on the Company
Disclosure Statement, there are no existing options, warrants, calls,
subscriptions or other rights, agreements, arrangements or commitments of any
character, relating to the issued or unissued capital stock of the Company or
any of the Subsidiaries, obligating the Company or any of the Subsidiaries to
issue, transfer or sell or cause to be issued, transferred or sold any shares of
capital stock or Voting Debt of, or other equity interest in, the Company or any
of the Subsidiaries or securities convertible into or exchangeable for such
shares or equity interests or obligations of the Company or any of the
Subsidiaries to grant, extend or enter into any such option, warrant, call,
subscription or other right, agreement, arrangement or commitment. There are no
outstanding contractual obligations of the Company or any of the Subsidiaries to
repurchase, redeem or otherwise acquire any capital stock of the Company or any
of its Subsidiaries. Each of the outstanding shares of capital stock of each of
the Company's Subsidiaries is duly authorized, validly issued, fully paid and
nonassessable, and such shares of the Subsidiaries as are owned by the Company
or by a wholly owned Subsidiary are free and clear of any lien, claim, option,
charge, security interest, limitation, encumbrance and restriction of any kind
(any of the foregoing being a "Lien"). Section 4.07 of the Company Disclosure
Statement contains a complete list as of the date hereof of each Subsidiary and
sets forth with respect to each of the Subsidiaries its name and jurisdiction of
organization and the number of shares of capital stock or share capital owned by
the Company and each other person.

                  SECTION 4.08. REGISTRATION STATEMENT; PROXY STATEMENT. Except
for information concerning the Parent that the Parent has provided for inclusion
or incorporation by reference in the Proxy Statement, such information, at the
date the Proxy Statement is first mailed to stockholders, at the time of the
Special Meetings and at the Effective Time, shall not contain any untrue

requirements of the Exchange Act or the Securities Act of 1933, as amended, and
the rules and regulations of the SEC promulgated thereunder applicable, as the
case may be, to such SEC Reports, and none of the SEC Reports contained any
untrue statement of a material fact or omitted to state a material fact required

of income and cash flows (including in each case the related notes thereto) of
the Company contained in the Forms 10-Q for the periods ended March 31, 1999,
included in the SEC Reports (the "Quarterly Financial Statements") have been

                  (d) The Company and the Subsidiaries have no liabilities or
obligations of any nature (whether absolute, accrued, contingent, unliquidated,
conditional or otherwise) except for liabilities or obligations (i) reflected or
reserved against on the balance sheet as at March 31, 1999 included in the
Quarterly Financial Statements (the "Company Balance Sheet") or (ii) which would
not, individually or in the aggregate, have a Material Adverse Effect on the
Company.

                  SECTION 4.10. INFORMATION. None of the information supplied by
the Company in writing specifically for inclusion or incorporation by reference
in (i) the Offer Documents, (ii) the Schedule 14D-9 (including the information

Rule 14f-1 thereunder), (iii) the Proxy Statement or (iv) any other document to
be filed with the SEC or any other Governmental Entity in connection with the

make the statements made therein, in light of the circumstances under which they
were made, not misleading. The Statement will comply as to form in all material
respects with the provisions of the Exchange Act and the rules and regulations
thereunder. Notwithstanding the foregoing, no representation is made by the
Company with respect to statements made in any such documents based on
information supplied by or on behalf of Parent or the Purchaser in writing
specifically for inclusion in the Statement.

                  SECTION 4.11. LITIGATION. There is no suit, action, proceeding
or governmental investigation before any commission or other administrative
authority pending or, to the knowledge of the Company, threatened against or

that, individually or in the aggregate,


                                     -20-

would not have a Material Adverse Effect on the Company, nor is there any
judgment, decree, injunction or order of any Governmental Entity or
arbitrator outstanding against the Company or any of the Subsidiaries, except
for judgments, decrees, injunctions and orders that would not, individually
or in the aggregate, have a Material Adverse Effect on the Company. There are
no facts known to the Company which, if known by a potential claimant or any
Governmental Entity, would reasonably give rise to a claim or proceeding
which, if asserted or conducted would be reasonably likely to have a Material
Adverse Effect on the Company.

                  SECTION 4.12.     COMPLIANCE WITH APPLICABLE LAWS; PERMITS.

individually and in the aggregate, would not have a Material Adverse Effect on
the Company. The business operations of the Company and the Subsidiaries have
not been conducted in violation of any law, ordinance or regulation of any
Governmental Entity, except for possible violations which, individually or in
the aggregate, would not have a Material Adverse Effect on the Company.

                  (b) Each of the Company and the Subsidiaries is in possession
of all franchises, grants, authorizations, licenses, establishment
registrations, product listings, permits, easements, variances, exceptions,

necessary for the Company or any Subsidiary to own, lease and operate its
properties or to produce, store, distribute and market its products or otherwise
to carry on its business as it is now being conducted (the "Company Permits"),
except where the failure to have, or the suspension or cancellation of, any of
the Company Permits would not, individually or in the aggregate, have a Material
Adverse Effect on the Company, and, as of the date of this Agreement, no
suspension or cancellation of any of the Company Permits is pending or, to the
knowledge of the Company, threatened, except where the failure to have, or the
suspension or cancellation of, any of the Company Permits would not,
individually or in the aggregate, have a Material Adverse Effect on the Company.
Neither the Company nor any Subsidiary is in conflict with, or in default or
violation of, (i) any Law applicable to the Company or


                                     -21-

any Subsidiary or by which any property or asset of the Company or any
Subsidiary is bound or affected or (ii) any Company Permits, except in the

state or local statute, law, ordinance, regulation, rule, code, order, other
requirement or rule of law of the United States or any other jurisdiction,
including, without limitation, the Federal Food, Drug, and Cosmetic Act (the

                  (iii) all of the clinical studies which have been, or are

         FDA or similar governmental agency, or committed an act, made a
         statement or failed to make a statement that could reasonably be
         expected to provide a basis for the FDA or similar governmental

         Material Facts, Bribery, and Illegal Gratuities" or similar
         governmental policy, rule, regulation or law;

         subsidiaries or affiliates has been convicted of any crime or engaged
         in any conduct for which debarment or similar punishment is mandated or
         permitted by any applicable law.

FDCA or the CSA of the Company or any product of the Company, including, but

Material Adverse Effect on the Company.

                  SECTION 4.13.     EMPLOYEE BENEFIT PLANS.

                  (a) Section 4.13 of the Company Disclosure Statement includes
a complete list of all bonus, profit sharing, thrift, compensation, stock
option, restricted stock, stock purchase, pension, retirement, savings, welfare,
deferred compensation, employment, termination, severance, incentive, or other
employee benefit plans, programs and agreements providing benefits to any
employee, former employee, director or former director of the Company or any of
the Subsidiaries sponsored or maintained by or on behalf of the Company or any
of the Subsidiaries or to which the Company or any of the Subsidiaries
contributes or is obligated to contribute or otherwise may have liability
(collectively, the "Plans"). Without limiting the generality of the foregoing,
the term "Plans" includes all employee welfare benefit plans within the meaning
of Section 3(l) of the Employee Retirement Income Security Act of 1974, as
amended, and the regulations thereunder ("ERISA") and all employee pension
benefit plans within the meaning of Section 3(2) of ERISA.

                  (b) With respect to each Plan, the Company has made available
to Parent a true, correct and complete copy of: (i) all plan documents, benefit
schedules, trust agreements, and insurance contracts and other funding vehicles,
if any; (ii) the most recent Annual Report (Form 5500 Series) and accompanying
schedule, if any; (iii) the current summary plan description, if any; (iv) the
most recent annual financial report, if any; (v) the most recent actuarial
report, if any; and (vi) the most recent determination letter from the Internal
Revenue Service (the "IRS"), if any.

                  (c) The Company and each of the Subsidiaries has complied, and
is now in compliance, in all material respects with all provisions of ERISA, the
Code and all laws and regulations applicable to the Plans. With respect to each
Plan that is intended to be a "qualified plan" within the meaning of Section
401(a) of the Code, the IRS has issued a favorable determination letter, and to
the knowledge of the Company nothing has occurred at the date hereof that would
reasonably be expected to cause the loss of such qualification.

                  (d) All contributions required to be made to any Plan by
applicable law or regulation or by any plan document or other contractual
undertaking, and all premiums due or payable with respect to insurance policies
funding any Plan, for any period through the date hereof have been timely made
or paid in full or, to the extent not required to be made or paid on or before
the date hereof, have been fully reflected in the financial statements of the
Company included in the SEC Reports to the extent required under GAAP.

                  (e) With respect to each plan which is subject to Title IV or
Section 302 of ERISA or Section 412 of the Code maintained or contributed to (or
required to be contributed to) by the Company, any Subsidiary or any ERISA
Affiliate (as hereinafter defined), (i) there does not now exist, nor do any
circumstances exist that could result in, any liability of the Company or any of
the Subsidiaries under Title IV of ERISA (other than for the payment of
premiums, all of which have been paid when due), (ii) neither the Company nor
any of the Subsidiaries has incurred any accumulated funding deficiency within
the meaning of Section 302 of ERISA or Section 412 of the Code (whether or not
waived) and there has been no waiver or application for a waiver of any minimum
funding standard or extension of any amortization period under Section 412 of
the Code or Part 3 of Subtitle B of Title I of ERISA, (iii) no "reportable
event" (as such term is defined in Section 4043 of ERISA and the regulations
thereunder), except as waived by PBGC regulation, has occurred or is expected to
occur, (iv) no notice of intent to terminate has been filed with the Pension
Benefit Guaranty Corporation, (v) the Pension Benefit Guaranty Corporation has
not instituted any proceedings to terminate the plan or to appoint a trustee to
administer the plan, and (vi) there has been no event requiring disclosure under
Section 4063(a) of ERISA. For purposes of this Section 4.13, the term "ERISA
Affiliate" shall mean any business or entity (whether or not incorporated) which
is a member of the same "controlled group of corporations", under "common
control" or an "affiliated service group" with the Company or any Subsidiary
within the meaning of Section 414(b), (c) or (m) of the Code, or is under
"common control" with the Company or any Subsidiary within the meaning of
Section 4001(a)(14) of ERISA.

                  (f) Neither the Company nor any Subsidiary nor any ERISA
Affiliate has been required to contribute to, or incurred any withdrawal
liability (within the meaning of Section 4201 of ERISA) with respect to any plan
which is a multiemployer plan as defined in ERISA Section 3(37) (a
"Multiemployer Plan"). Neither the Company nor any Subsidiary nor any ERISA
Affiliate


                                     -25-

<PAGE>

has completely or partially withdrawn from any Multiemployer Plan. No
Multiemployer Plan as to which the Company, any Subsidiary or any ERISA
Affiliate is required to contribute is in reorganization within the meaning of
Part 3 of Subtitle E of Title IV of ERISA. The Company has delivered to Parent a
schedule showing the contributions of the Company, any of the Subsidiaries, and
any ERISA Affiliates to each of the Multiemployer Plans for the most recent five
plan years.

                  (g) The execution of, and performance of the transactions
contemplated in, this Agreement will not, either alone or upon the occurrence of
subsequent events, result in any payment (whether of severance pay or
otherwise), acceleration, forgiveness of indebtedness, vesting, distribution,
increase in benefits or obligation to fund benefits with respect to any employee
or former employee of the Company or any of the Subsidiaries. The only severance
agreements or severance policies applicable to the Company or any of the
Subsidiaries in the event of a change of control of the Company are the
agreements referred to in Section 4.13 of the Company Disclosure Statement.

                  (h) There are no pending actions, claims or lawsuits which
have been asserted, instituted or, to the knowledge of the Company, threatened
in connection with any of the Plans (other than routine claims for benefits).

                  (i) Neither the Company nor any of the Subsidiaries maintains
or contributes to any plan or arrangement which provides or has any liability to
provide life insurance or medical or other welfare benefits to any employee,
former employee, director or former director upon his retirement or termination
of service (other than continuation coverage required under Section 4980B of the
Code), and neither the Company nor any of the Subsidiaries has ever represented,
promised or contracted (whether in oral or written form) to any employee, former
employee, director or former director that such benefits would be provided.

                  (j) The Company, the Subsidiaries and their ERISA Affiliates
are in compliance with the continuation coverage provisions of Section 601 et
seq. of ERISA and Section 4980B of the Code.

                  (k) None of the Company, any of its Subsidiaries or any
employee of the foregoing, nor any trustee, administrator, other fiduciary or
any other "party in interest" or "disqualified person" with respect to the
Plans, has engaged in a "prohibited transaction" (as such term is defined in
Section 4975


                                      -26-

<PAGE>

of the Code or Section 406 of ERISA) that could result in a material tax or
penalty on the Company or its Subsidiaries under Section 4975 of the Code or
Section 502(i) of ERISA.

                  SECTION 4.14.     INTELLECTUAL PROPERTY.

                  (a) Except as would not, individually and in the aggregate,
have a Material Adverse Effect on the Company, (i) the Company and each of the
Subsidiaries owns, has the right to acquire or is licensed or otherwise has the
right to use and has maintained in good standing (in each case, clear of any

claims the right to use in connection with similar or closely related goods and

to any of the Intellectual Property; (v) the Company has no knowledge of any
claim that any third party asserts ownership rights in any of the Intellectual
Property; (vi) the Company has no knowledge of any claim or knowledge of any
facts that would give the Company any reason to reasonably believe that the
Company's or its Subsidiaries' use of any Intellectual Property infringes any
right of any third party; (vii) the Company has no knowledge and there are no
facts known to the Company that would give the Company any reasonable basis to
believe that any third party is infringing on any of the Company's or its
Subsidiaries' rights in any of the Intellectual Property; (viii) the Company has
no knowledge and there are no facts known to the Company that would give the
Company any reasonable basis to believe that any of its actions or the actions

foregoing; and trade secrets and rights in any jurisdiction to limit the use or
disclosure thereof by any person.

<PAGE>

IRS or any other taxing authority with respect to any period that is still

                  SECTION 4.18. MATERIAL CONTRACTS. (a) Other than as disclosed
in Section 4.18 of the Company Disclosure Statement, there are no (i) agreements
of the Company or any of the Subsidiaries containing an unexpired covenant not
to compete applying to the Company or any of the Subsidiaries, (ii) employment
or consulting agreements, or arrangements, (iii) collective bargaining
agreements, (iv) interest rate, currency or commodity hedging, swap or similar
derivative transactions to which the Company or any of the Subsidiaries is a
party, (v) material agreements providing for payment based on revenues, sales or
profits, (vi) agreements between the Company or any of the Subsidiaries, on the
one hand, and any affiliate of the Company, on the other hand, (vii) any other

other contracts or amendments thereto that would be required to be filed and
have not been filed as a exhibit to a Form 10-K filed by the Company with the
SEC as of the date of this Agreement (collectively, the "Material Contracts").
Assuming each Material Contract constitutes a valid and binding obligation of
each other party thereto, each Material Contract is a valid and binding
obligation of the Company or the applicable Subsidiary, as the case may be. To
the Company's knowledge, each Material Contract is a valid and binding
obligation of each other party thereto, and each such Material Contract is in
full force and effect and is enforceable by the Company or the applicable
Subsidiary in accordance with its terms, except as such enforcement may be
limited by the Bankruptcy Exceptions and subject to general principles of
equity. To the knowledge of the Company, there are no existing defaults (or
circumstances or events that, with the giving of notice or lapse of time or both
would become defaults) of the Company, any Subsidiary or any third party under
any of the Material Contracts. Neither the Company nor any of its Subsidiaries
is a party to, or bound by any unexpired, undischarged or unsatisfied written or
oral contract, agreement, indenture, mortgage, debenture, note or other
instrument under the terms of which performance by the Company or its
Subsidiaries according to the terms of this Agreement will be a default of a
material provision under or an event of acceleration, or grounds for
termination, or


                                      -33-

<PAGE>

whereby timely performance by the Company of this Agreement may be prohibited
or delayed. Immediately after the Effective Time, except as contemplated by
this Agreement, neither the Company nor any of its Subsidiaries will be bound
by the terms of any stock option agreement, registration rights agreement,
stockholders agreement, management agreement, consulting agreement or any
other agreement relating to the equity or management of the Company or its
Subsidiaries.

                  (b) The Company's relationship with Merck & Co., Inc.
("Merck") is in good standing. To the Company's knowledge, Merck is willing to
negotiate a firm supply agreement with the Company for MK3 (subject to
acceptable terms).

                  SECTION 4.19. INSURANCE. The Company and the Subsidiaries have
obtained and maintained in full force and effect insurance with responsible and
reputable insurance companies or associations in such amounts, on such terms and
covering such risks, as is in the Company's judgment adequate to insure against
risks to which the Company is normally exposed in its day-to-day operations,
consistent with industry practice for companies (i) engaged in similar
businesses and (ii) of at least similar size to that of the Company and the
Subsidiaries, and have maintained in full force and effect public liability
insurance, insurance against claims for personal injury or death or property
damage occurring in connection with any of the activities of the Company or the
Subsidiaries or any of the properties owned, occupied or controlled by the
Company or any of the Subsidiaries, in such amount as reasonably deemed
necessary by the Company. To the Company's knowledge, each such policy is in
full force and effect, no notice of termination, cancellation or reservation of
rights has been received with respect to any such policy, there is no default
with respect to any provision contained in any such policy, and there has not
been any failure to give any notice or present any claim under any such policy
in a timely fashion or in the manner or detail required by any such policy,
except for any such failures to be in full force and effect, any such
terminations, cancellations, reservations or defaults, or any such failures to
give notice or present claims which would not, individually or in the aggregate,
have a Material Adverse Effect on the Company. The Company Balance Sheet
reflects adequate reserves for any insurance programs which require (or have
required) the Company or any of the Subsidiaries to retain a portion of each
loss, including, but not limited to, deductible and self-insurance programs.

                  SECTION 4.20. YEAR 2000 Either (i) all Information Systems and
Equipment (as defined below) are in all material respects either Year 2000
Compliant (as defined below) or (ii) any reprogramming, remediation, or any
other corrective action, including the internal testing of all such Information
Systems and Equipment, will be completed in all material respects by July 31,
1999. Further, to the extent that such reprogramming/remediation and testing
action is required, the cost thereof, as well as the cost of the reasonably
foreseeable consequence of failure to become Year 2000 Compliant, to the Company
and the Subsidiaries (including, without limitation, reprogramming errors and
the failure of other systems or equipment) will not result in a Material Adverse
Effect on the Company.

                  "Year 2000 Compliant" means that all Information Systems and
Equipment accurately process date data (including, but not limited to,
calculating, comparing and sequencing), before, during and after the year 2000,
as well as same and multi-century dates, or between the years 1999 and 2000,
taking into account all leap years, including the fact that the year 2000 is a
leap year, and further, that when used in combination with, or interfacing with,
other Information Systems and Equipment, shall accurately accept, release and
exchange date data, and shall in all material respects continue to function in
the same manner as it performs today and shall not otherwise materially impair
the accuracy or functionality of Information Systems and Equipment.

                  "Information Systems and Equipment" means all material
computer hardware, firmware and software, as well as other information
processing systems, or any equipment containing embedded microchips, whether
directly owned, licensed, leased, operated or otherwise controlled by the
Company or any of the Subsidiaries, including through third-party service
providers, and which, in whole or in part, are integral to, the Company's or any
of the Subsidiaries' conduct of their business.

                  SECTION 4.21 AFFILIATES. The Company has delivered to Parent
in Section 4.21 of the Company Disclosure Statement a list identifying all
persons who to the best of the Company's knowledge may be deemed to be
"affiliates" of the Company for purposes of Rule 145 under the Securities Act
("Affiliates") and, promptly after the execution of this Agreement, the Company
will deliver the written agreement of each such person promptly after execution
of this Agreement, substantially in the form of Annex III.

                         REPRESENTATIONS AND WARRANTIES
                           OF PARENT AND THE PURCHASER


                  Parent and the Purchaser represent and warrant to the Company

lease its properties and to carry on its business as it is now being conducted,
and is duly qualified or licensed to do business, and is in good standing, in
each jurisdiction in which the nature of its business or the properties owned,
operated or leased by it makes such qualification, licensing or good standing

transactions contemplated hereby have been duly and validly authorized and
approved by the respective Boards of Directors of Parent and the Purchaser and
no other corporate proceedings on the part of Parent or the Purchaser are
necessary to authorize or approve this Agreement or to consummate the
transactions contemplated hereby. This Agreement has been duly executed and
delivered by each of Parent and the Purchaser and, assuming the due and valid
authorization, execution and delivery by the Company, constitutes a valid and
binding obligation of each of Parent and the Purchaser enforceable against each
of them in accordance with its terms, except that such enforceability

the Purchaser, or any of their respective subsidiaries, is a party or by which
any of their respective properties or assets may be bound or affected, except,
in the case of clause (ii) and (iii), for any such Violation which would not,
individually or in the aggregate, have a Material Adverse Effect on Parent.

                  SECTION 5.04. BROKERS. Except for the engagement of Donaldson,
Lufkin & Jenrette Securities Corporation, none of the Parent nor the Purchaser
or any of their respective officers, directors, or employees has employed any

Representatives and destroy all memoranda, notes and other writings prepared

Company or the Company Representatives (and the Company will certify to
Parent that such destruction has occurred).

                  (c) The Company will assist Parent in securing access to Merck
in order to pursue business opportunities.

                  SECTION 6.03. REASONABLE BEST EFFORTS. (a) Subject to the

of the parties hereto agrees to use its reasonable best efforts to take, or
cause to be taken, all action, and to do, or cause to be done, and to assist and
cooperate with the other parties hereto in doing, as promptly as practicable,
all things necessary, proper or advisable under applicable laws and regulations
to ensure that the conditions set forth in Annex I and Article VII are satisfied
and to consummate and make effective the transactions contemplated by the Offer
and this Agreement, including, without limitation, (i) the filing of
Notification and Report Forms under the HSR Act with the Federal Trade
Commission (the "FTC") and the Antitrust Division of the Department of Justice

respond as promptly as practicable to any inquiries received from the FTC or the
Antitrust Division for additional information or documentation, (ii) the
obtaining of all necessary consents, approvals or waivers and (iii) the lifting
of any legal bar to the Merger. Parent shall cause Purchaser to perform all of
its obligations under this Agreement and shall not knowingly take any action
that would cause the Company to fail to perform its obligations hereunder. The
Company shall not knowingly take any action that would cause either Parent or
Purchaser to fail to perform its obligations hereunder.

                  (b) The Company shall prepare and file with the SEC as soon as

connection with the preceding sentences of this Section 6.03(b).

                  (c) In addition, if at any time prior to the Effective Time
any event or circumstance relating to either the Company or Parent or the
Purchaser or any of their respective subsidiaries, should be discovered by the
Company or Parent, as the case may be, and which should be set forth in an
amendment to the Offer Documents, Schedule 14D-9, Company Proxy Statement or the
Registration Statement, the discovering party will promptly inform the other
party of such event or circumstance. If at any time after the Effective Time any
further action is necessary or desirable to carry out the purposes of this
Agreement, including the execution of additional instruments, the proper
officers and directors of each party to this Agreement shall take all such
necessary action.

                  SECTION 6.04. PUBLIC ANNOUNCEMENTS. (a) So long as this
Agreement is in effect, Parent, the Purchaser and the Company agree to use
reasonable efforts to consult with each other before issuing any press release

                  (b) So long as this Agreement is in effect, the Company agrees
to provide Parent with notice and copies of any press release or any public
statement at least 24 hours prior to issuance; PROVIDED, that this provision
shall not prevent the Company from issuing a press release if the Company in
good faith determines that it must do so and makes reasonable attempts to so
notify Parent. Parent shall designate a single person with whom the Company
should communicate for purposes of this Section 6.04(b). The Company shall use
its reasonable efforts to accommodate any comments provided by Parent on a press
release before the end of such 24 hour period, but the Company shall maintain

                  SECTION 6.05.     INDEMNIFICATION.

                  (a) Parent agrees that all rights to indemnification now
existing in favor of any director or officer of the Company as provided in the
Company's Amended and Restated Certificate of Incorporation or by laws, in an
agreement between any such person and the Company, or otherwise in effect on the
date hereof shall survive the Merger and shall continue in full force and effect
after the Effective Time. Parent agrees that all rights to indemnification now
existing in favor of any director or officer of the Subsidiaries as provided in
the certificate of incorporation or by laws or similar organizational document,
in an agreement between any such person and such Subsidiary, or otherwise in
effect on the date hereof shall survive the Merger and shall continue in full
force and effect after the Effective Time. After the Effective Time, Parent also
agrees to and to cause any successors to indemnify all directors and officers of
the Company or of any of the Subsidiaries ("Indemnified Parties") to the fullest
extent permitted by applicable law with respect to all acts and omissions
arising out of such individuals' services as officers or directors of the
Company or any of the Subsidiaries or as trustees or fiduciaries of any plan for
the benefit of employees occurring at or prior to the Effective Time. Without
limitation of the foregoing, in the event that after the Effective Time any such
Indemnified Party is or becomes involved in any capacity in any action,
proceeding or investigation in connection with any matter, including, without
limitation, the transactions contemplated by this Agreement, occurring prior to,
and including, the Effective Time, Parent will pay, subject to applicable law,
as incurred such Indemnified Party's reasonable legal and other expenses of
counsel selected by the Indemnified Party and reasonably acceptable to Parent
(including the cost of any investigation and preparation) incurred in connection
therewith; PROVIDED, HOWEVER, that Parent shall not, in connection with any one
such action or proceeding or separate but substantially similar actions or
proceedings arising out of the same general allegations be liable for fees and
expenses of more than one separate firm of attorneys (in addition to any local
counsel) at any time for all Indemnified Parties. Parent shall be entitled to
participate in the defense of any such action or proceeding and counsel selected
by the Indemnified Party shall, to the extent consistent with their professional
responsibilities, cooperate with Parent and any counsel designated by Parent.
Parent shall, subject to applicable law, pay all reasonable expenses, including
attorneys' fees, that may be incurred by any Indemnified Party in enforcing the
indemnity and other obligations provided for in this Section 6.05.

                  (b) Parent agrees that the Company and, from and after the
Effective Time, the Surviving Corporation shall cause to be maintained in effect
for not less than six years from the Effective Time the current policies of the
directors' and officers' liability insurance maintained by the Company; PROVIDED
that the Surviving Corporation may substitute therefor policies of at least the
same coverage containing terms and conditions which are no less advantageous to
any Indemnified Party and provided that such substitution shall not result in
any gaps or lapses in coverage with respect to matters occurring at or prior to
the Effective Time; and PROVIDED, FURTHER, that the Surviving Corporation shall
not be required to pay an annual premium in excess of 200% of the last annual
premium paid by the Company prior to the date hereof and if the Surviving
Corporation is unable to obtain the insurance required by this Section 6.05(b)
it shall obtain as much comparable insurance as possible for an annual premium
equal to such maximum amount.

                  (c) The covenants in this Section 6.05 are intended for the
benefit of and shall be enforceable by each of the Indemnified Parties and their
respective heirs and legal representatives. The indemnification provided for
herein shall not be deemed exclusive of any other rights to which an Indemnified
Party is entitled, whether pursuant to law, contract or otherwise.

                  (d) In the event that the Surviving Corporation or Parent or
any of their respective successors or assigns (i) consolidates with or merges
into any other person and shall not be the continuing or surviving corporation
or entity of such consolidation or merger or (ii) transfers or conveys all or
substantially all of its properties and assets to any person, then, and in each
such case, to the extent necessary to effectuate the purposes of this Section
6.05, proper provision shall be made so that the successors and assigns of the
Surviving Corporation or Parent shall succeed to the obligations set forth in
this Section 6.05.

                  (e) OPERATIONS OF PURCHASER. Purchaser has been formed solely
for the purpose of engaging in the transactions contemplated hereby and prior to
the Effective Time will have engaged in no other business activities and will
have incurred no liabilities or obligations other than as contemplated herein.

                  SECTION 6.06.     NO SOLICITATION.

                  (a) The Company represents and warrants to, and covenants and
agrees with, Parent and the Purchaser that neither the Company nor any of the
Subsidiaries has any agreement, arrangement or understanding regarding an
Acquisition Transaction (as hereinafter defined) with any party expressing an
interest in an Acquisition Transaction that, directly or indirectly, would be
violated, or require any payments, by reason of the execution, delivery and/or
consummation of this Agreement. The Company shall, and shall cause the
Subsidiaries and its and their officers, directors, employees, investment
bankers, attorneys and other agents and representatives to, immediately cease
any existing discussions or negotiations with any person other than Parent or
the Purchaser (a "Third Party") heretofore conducted with respect to any
Acquisition Transaction. The Company shall not, and the Company shall cause the
Subsidiaries and its and their respective officers, directors, employees,
investment bankers, attorneys and other agents and representatives not to,
directly or indirectly, (x) solicit, initiate, continue, facilitate or encourage
(including by way of furnishing or disclosing non-public information) any
inquiries, proposals or offers from any Third Party with respect to, or that
could reasonably be expected to lead to, (i) any acquisition or purchase of 25%
or more of the assets or business of the Company and its subsidiaries, taken as
a whole, or a 25% or more voting equity interest in (including by way of a
tender offer), or (ii) any amalgamation, merger, consolidation or business
combination with, or any recapitalization or restructuring, or any similar
transaction involving, the Company (the foregoing clause (i) and (ii) being
referred to collectively as an "Acquisition Transaction"), or (y) negotiate,
explore or discuss in any way with any Third Party with respect to any
Acquisition Transaction or enter into, approve or recommend any agreement,
arrangement or understanding requiring the Company to abandon, terminate or fail
to consummate the Offer and/or the Merger or any other transaction contemplated
hereby. Notwithstanding anything to the contrary in the foregoing, the Company
may, prior to the Special Meeting, in response to an unsolicited written
proposal with respect to an Acquisition Transaction involving the acquisition of
all or substantially all of the Shares (or all or substantially all of the
assets of the Company and the Subsidiaries) from a Third Party (i) furnish or
disclose non-public information to such Third Party, (ii) negotiate, discuss or
otherwise communicate with such Third Party and (iii) in the case of an
unsolicited tender offer for Shares, withdraw or modify (or resolve to withdraw
or modify) in a manner adverse to Parent the approval or recommen-

dation of this Agreement and the transactions contemplated hereby or
recommend (or resolve to recommend) such Acquisition Transaction with a Third
Party to Shareholders (including disclosing to the Company's stockholders
such position contemplated by Rules l4d-9 and 14e-2 promulgated under the
Exchange Act), in each case only if the Board of Directors of the Company
determines reasonably and in good faith: (1) after consultation with and
based (as to legal matters) upon advice of outside counsel that it is
required to do so in the exercise of its fiduciary obligations, (2) (after
consultation with Warburg Dillon Read LLC) that such proposed Acquisition
Transaction or tender offer is more favorable to the Shareholders from a
financial point of view than the transaction contemplated hereby (including
any adjustment to the terms and conditions proposed by Parent and the
Purchaser in response to such proposed Acquisition Transaction (a proposal
with respect to such Acquisition Transaction meeting the requirements of
clauses (1) and (2) is referred to herein as a "Superior Proposal"). Prior to
furnishing or disclosing any non-public information to such Third Party, the
Company shall receive from such Third Party an executed confidentiality
agreement with terms no less favorable in the aggregate to the Company than
those contained in the Confidentiality Agreement between the Company and
Parent (the "Confidentiality Agreement"), but which confidentiality agreement
shall not provide for any exclusive right to negotiate with the Company or
any payments by the Company. The Company shall give Parent one day's written
notice prior to entering into any such Confidentiality Agreement. The Company
shall provide to Parent copies of all such non-public information delivered
to such Third Party concurrently with such delivery. Notwithstanding the
foregoing, the Board of Directors of the Company shall not, and the Company
shall not, withdraw or modify (or resolve to withdraw or modify) in a manner
adverse to Parent the approval or recommendation of this Agreement or any of
the transactions contemplated hereby, or recommend (or resolve to recommend)
an Acquisition Transaction with a Third Party to the Shareholders or enter
into a definitive agreement with respect to a Superior Proposal unless (x)
the Company has given Parent three business days' notice of the intention of
the Board of Directors to withdraw or modify (or resolve to withdraw or
modify) in a manner adverse to Parent the approval or recommendation of this
Agreement or any of the transactions contemplated hereby, or recommend (or
resolve to recommend) an Acquisition Transaction with a Third Party to the
Shareholders or the intention of the Company to enter into such definitive
agreement, as the case may be, (y) if Parent makes a counter-proposal within
such three business day period, the Board of Directors of the Company shall
have determined, in light of any such counter-


                                      -57-

proposal, that the Third Party Acquisition Transaction proposal is still a
Superior Proposal, and (z) the Company concurrently terminates this Agreement
in accordance with the terms hereof and pays any Termination Fee (as defined)
required under Section 8.03(c).

                  (b) The Company shall promptly (but in any event within one
day of the Company becoming aware of same) advise Parent of the receipt by the
Company, any of the Subsidiaries or any of its or their bankers, attorneys or
other agents or representatives of any inquiries or proposals relating to an
Acquisition Transaction and any actions taken pursuant to Section 6.06(a). The
Company shall promptly (but in any event within one day of the Company becoming
aware of same) provide Parent with a copy of any such inquiry or proposal in
writing and a written statement with respect to any such inquiries or proposals
not in writing, which statement shall include the identity of the parties making
such inquiries or proposal and all the material terms thereof. The Company
shall, from time to time, promptly (but in any event within one day of the
Company becoming aware of same) inform Parent of the status and content of and
developments with respect to any discussions regarding any Acquisition
Transaction with a Third Party. The Company shall, from time to time, promptly
(but in any event within one day of the Company becoming aware of same) inform
Parent in writing of (i) the calling of meetings of the Board of Directors of
the Company to take action with respect to such Acquisition Transaction, (ii)
the execution of any letters of intent, memoranda of understanding or similar
non-binding agreements with respect to such Acquisition Transaction, (iii) the
waiver of any standstill agreement to which the Company is or becomes a party,
(iv) the determination by the Board of Directors of the Company to recommend to
the Shareholders that they approve or accept a Superior Proposal or withdraw or
modify in a manner adverse to the Parent its approval or recommendation of this
Agreement or the transactions contemplated hereby, (v) the determination by the
Company to publicly disclose receipt of a Superior Proposal and (vi) the waiver
by the Company of any confidentiality agreement with a person proposing a
Superior Proposal.

                  SECTION 6.07. NOTIFICATION OF CERTAIN MATTERS. Parent and the
Company shall promptly notify each other of (a) the occurrence or non-occurrence
of any fact or event which would (i) cause any representation or warranty
contained in this Agreement to be untrue or inaccurate in any material respect
at any time from the date hereof to the Effective Time or (ii) cause any
covenant, condition or agreement hereunder not


                                      -58-

of the Company or Parent, as the case may be, to comply with or satisfy any
covenant, condition or agreement to be complied with or satisfied by it
hereunder in any material respect; PROVIDED, HOWEVER, that no such
notification shall affect the representations or warranties of any party or
the conditions to the obligations of any party hereunder.

                  SECTION 6.08. STATE TAKEOVER LAWS. The Company shall, upon the
request of the Purchaser, take all reasonable steps to assist in any challenge
by the Purchaser to the validity or applicability to the transactions
contemplated by this Agreement, including the Offer and the Merger, and the
Stock Option Agreement of any state takeover law. The Board of Directors of the
Company shall not amend, modify or rescind the approval of any purchase of
Shares in the Offer or under the Stock Option Agreement for purposes of Section
203 of the GCL. The Company will use its reasonable best efforts to ensure that
the provisions of any applicable or alleged or asserted to be applicable state
takeover law will not be applicable to the Offer, the Merger or any of the other
transactions contemplated by this Agreement.

                  SECTION 6.09. ENVIRONMENTAL APPROVALS. The Company shall
obtain all approvals, consents and authorizations and make all filings required

and performance of this Agreement and the consummation of the transactions
contemplated hereby.

commercially reasonable efforts to list on the NYSE and the Toronto Stock
Exchange, upon official notice of issuance, the Parent Common Stock to be issued
in connection with the Merger.

                  SECTION 6.11 AFFILIATES. The Company shall advise Parent in
writing of any person who, to the Company's knowledge, becomes an Affiliate
after the date hereof and prior to the Effective Time and shall use all
commercially reasonable efforts to cause each such person to deliver to Parent,
no later than the date such person becomes an Affiliate, a written agreement
substantially in the form of Annex III hereto. Parent shall use all commercially
reasonable efforts to satisfy for two years after the Effective Time the
requirements of Rule 144(c) under the Securities Act.

its Subsidiaries as Parent shall specify, effective at the Effective Time. In
connection with any such resignation, the directors shall simultaneously
reconvey their directors' qualifying shares, if any, to the applicable
Subsidiary or such other persons as Parent shall specify at no additional
expense to Parent, Purchaser or such Subsidiary other than customary expenses
directly relating to the transfer and issuance of directors' qualifying shares,
if any.

                  (b) The Company will (i) promptly give notice to Paul Kennedy
that its engagement of him as financial advisor pursuant to a letter agreement
dated June 24, 1999 shall terminate on the earliest possible date pursuant to

Section 6.06(a) and (D) the Company has paid to Parent by wire transfer or
immediately available funds to an account specified by Parent a fee of $5.5

this Agreement, except as provided in this Section 8.05 and except that nothing
herein shall relieve any party from liability for any breach of this Agreement.

                  (b) In the event of a termination of this Agreement by Parent
pursuant to Section 8.02(c) then, in any such case, the Company shall within two
business days of such termination pay Parent by wire transfer or immediately

                  (c) In the event of a termination of this Agreement (i)
pursuant to Section 8.01(c) based on the Company's actions or omissions or (d)
or (ii) by Parent pursuant to Section 8.02(a) or (b), and in the case of either
clause (i) or clause (ii), prior to such termination any person shall have made
a proposal with respect to an Acquisition Transaction with the Company or its
stockholders, and, if prior to or within twelve months after such termination
the Company or any subsidiary of the Company enters into a definitive agreement
with a third party with respect to, or consummates, an Acquisition Transaction,
then the Company, as a condition to and prior to the earlier of entering into
any such definitive agreement and consummating an Acquisition Transaction, shall
pay Parent by wire transfer or immediately available funds to an account
specified by Parent, a fee of $5.5 million.

                  (d) The Company acknowledges that Parent would suffer direct
and substantial damages, which damages cannot be determined with reasonable
certainty in the event that this Agreement shall be terminated under

the parties would not enter into this Agreement. Parent and Purchaser
acknowledge that whenever a fee is payable by the Company to Parent pursuant
this Article VIII, payment by the Company of such fee in accordance with the
terms of the applicable paragraph shall be deemed a release of the Company from
all liability under this Agreement.

                             CONDITIONS TO THE OFFER


                  Notwithstanding any other provisions of the Offer, in addition
to (and not in limitation of) the Purchaser's right to extend and amend the
Offer at any time in its sole discretion (subject to the terms of the Merger
Agreement), the Purchaser shall not be required to accept for payment or,
subject to any applicable rules and regulations of the SEC, including Rule
14e-1(c) under the Exchange Act, pay for, and may delay the acceptance for
payment of or, subject to the regulations referred to above, the payment for,
any tendered Shares, and may terminate or amend the Offer, if (i) there are not
validly tendered and not withdrawn prior to the expiration date for the Offer
(the "Expiration Date") that number of Common Shares which, together with Shares
beneficially owned by Parent or its affiliates, represent at least 40% of the
outstanding Common Shares on the date of purchase (the "Minimum Condition")
PROVIDED; that Purchaser shall only be required to accept for payment and to
purchase that number of Common Shares which, together with Shares beneficially
owned by Parent or its affiliates, represents not more than 49% of the
outstanding Common Shares on the date of purchase, (ii) any applicable waiting
periods under the HSR Act or any applicable foreign antitrust statute shall not
have expired or (iii) at any time on or after July 25, 1999 and before the
expiration of the Offer, any of the following events shall occur:

                  (a) there shall have been any action taken, or any statute,
         rule, regulation, judgment, order or injunction promulgated, entered,
         enforced, enacted, issued or deemed applicable to the Offer or the
         Merger by any domestic or foreign court or other Governmental Entity
         which directly or indirectly (i) prohibits, or makes illegal, the
         acceptance for payment, payment for or purchase of Shares or the
         consummation of the Offer, the Merger or the other transactions
         contemplated by this Agreement, (ii) renders Purchaser unable to accept
         for payment, pay for or purchase some or all of the Shares, (iii)
         imposes material limitations on the ability of Parent effectively to
         exercise full rights of ownership of the Shares, including the right to
         vote the Shares purchased by it on all matters properly presented to
         the Company's stockholders, or (iv) otherwise has a Material Adverse
         Effect on the Company;


<PAGE>

                  (b) (i) the representations and warranties of the Company
         contained in this Agreement at the date hereof and as of the
         consummation of the Offer with the same effect as if made at and as of
         the consummation of the Offer (except as to any such representation or
         warranty which speaks as of a specific date) shall not be true and
         correct in any respect that is reasonably likely to have a Material
         Adverse Effect on the Company (or if such representations and
         warranties are qualified by reference to materiality or a Material
         Adverse Effect on the Company, shall not be true and correct), (ii) the
         Company shall have failed to perform in all material respects its
         covenants or agreements contained in this Agreement which would have a
         Material Adverse Effect on the Company or materially adversely affect
         (or materially delay) the ability of Purchaser to consummate the Offer
         or of Parent, Purchaser or the Company to consummate the Merger, and
         the Company has not cured such breach within ten business days after
         notice by Parent or Purchaser thereof; or

                  (c) it shall have been publicly disclosed that (i) any person
         or "group" (as defined in Section 13(d)(3) of the Exchange Act) shall
         have acquired or entered into a definitive agreement or agreement in
         principle to acquire beneficial ownership of more than 25% of the
         Shares or any other class of capital stock of the Company, through the
         acquisition of stock, the formation of a group or otherwise, or shall
         have been granted any option, right or warrant, conditional or
         otherwise, to acquire beneficial ownership of more than 25% of the
         Shares and (ii) such person or group shall not have tendered such
         Shares pursuant to the Offer;

                  (d) (i) the Company Board shall have withdrawn, or modified or
         changed in a manner adverse to Parent (including by amendment of the
         Schedule 14D-9), its recommendation of the Offer, this Agreement or the
         Merger, or recommended another proposal or offer, or the Company Board,
         shall have resolved to do any of the foregoing or (ii) the Company
         enters into any agreement to consummate any Acquisition Proposal with a
         Third Party;

                  (e) this Agreement shall have terminated in accordance with
         its terms;

                  (f) there shall have occurred (i) any general suspension of
         trading in, or limitation on prices for, securities on the New York
         Stock Exchange, the American Stock


                                      -2-

<PAGE>

         Exchange, the Toronto Stock Exchange or the NASDAQ Stock Market
         which lasts twenty four hours, (ii) a declaration of a banking
         moratorium or any suspension of payments in respect of banks in
         Canada or the United States (whether or not mandatory) or (iii) any
         limitation (whether or not mandatory) by any United States or
         Canadian governmental authority on the extension of credit generally
         by banks or other financial institutions;

which in the good faith judgment of Parent, in any such case, and regardless of
the circumstances (including any action or inaction by Parent) giving rise to
such condition makes it inadvisable to proceed with the Offer or the acceptance
for payment of or payment for the Shares.

                  The foregoing conditions (other than the Minimum Condition)
are for the sole benefit of Parent and Purchaser and may be waived by Parent and
Purchaser, in whole or in part at any time and from time to time, in the sole
discretion of Parent and Purchaser. The failure by Parent and Purchaser at any
time to exercise any of the foregoing rights shall not be deemed a waiver of any
such right and each such right shall be deemed an ongoing right which may be
asserted at any time and from time to time.

                  The capitalized terms used in this Annex I shall have the
meanings set forth in the Agreement to which it is annexed, except that the term
"Merger Agreement" shall be deemed to refer to the Agreement to which this Annex
I is appended.

                              MERGER CONSIDERATION


                  Each Share issued and outstanding immediately prior to the
Effective Time, (other than shares to be canceled pursuant to Section 2.07)
shall be converted into the right to receive a number of shares of Parent Common
Stock equal to the Exchange Ratio (as such term is defined below) as the "Merger
Consideration."

                  The "Exchange Ratio" shall be determined as follows:

                  (i) if the Average Trading Price of a share of Parent Common
Stock is less than $45.000, the Exchange Ratio shall equal .1556; (ii) if the
Average Trading Price of a share of Parent Common Stock is greater than or equal
to $45.000, but less than or equal to $58.625, the Exchange Ratio shall equal a
fraction (rounded to the nearest ten-thousandth) determined by dividing $7.00 by
the Average Trading Price of a share of Parent Common Stock; (iii) if the
Average Trading Price of a share of Parent Common Stock is greater than $58.625
but less than or equal to $62.810, the Exchange Ratio shall equal .1194 and (iv)
if the Average Trading Price is greater than $62.810, the Exchange Ratio shall
equal a fraction (rounded to the nearest ten-thousandth) determined by dividing
$7.50 by the Average Trading Price of a share of Parent Common Stock. The
Exchange Ratio shall be subject to appropriate adjustment in the event of a
stock split, stock dividend or recapitalization after the date of this Agreement
applicable to shares of the Parent Common Stock.

                  "Average Trading Price" shall be equal to the average of the
daily closing prices per share of Parent Common Stock on the New York Stock
Exchange ("NYSE") Composite Transactions Reporting System, as reported in The
Wall Street Journal for the fifteen trading days ending on the date immediately
prior to the second full NYSE trading day immediately preceding the Closing
Date.

                        FORM OF COMPANY AFFILIATE LETTER



Biovail Corporation International
2488 Dunwin Drive
Mississauga, Ontario
Canada, L5L 1J9


Gentlemen:

                  The undersigned, a holder of shares of common stock, par value
$.01 per share ("Company Common Stock"), of Fuisz Technologies Ltd., a Delaware
corporation (the "Company"), is entitled to receive, in connection with the
merger (the "Merger") between the Company and a direct wholly owned subsidiary
of Biovail Corporation International ("Parent"), shares of the common stock of
Parent ("Shares"). The undersigned acknowledges that the undersigned may be
deemed an "affiliate" of the Company within the meaning of Rule 145 ("Rule 145")
promulgated under the Securities Act of 1933, as amended (the "Act"), although
nothing contained herein should be construed as an admission of such fact.

                  If, in fact, the undersigned is an affiliate under the Act,
the undersigned's ability to sell, assign or transfer the Shares received by the
undersigned upon conversion of any shares of Company Common Stock pursuant to
the Merger may be restricted unless such transaction is registered under the Act
or an exemption from such registration is available. The undersigned understands
that such exemptions are limited and the undersigned has obtained advice and
counsel as to the nature and conditions of such exemptions, including
information with respect to the applicability to the sale of such securities of
Rules 144 and 145(d) promulgated under the Act.

                  The undersigned hereby represents to and covenants with Parent
that the undersigned will not sell, assign or transfer any of the Shares
received by the undersigned upon conversion of shares of Company Common Stock
pursuant to the Merger except (i) pursuant to an effective registration
statement under the Act, (ii) in conformity with the limitations specified by
Rules 144 and 145(d), (iii) in a transaction which, in the opinion of counsel
reasonably satisfactory to


<PAGE>

Parent is not required to be registered under the Act or (iv) in a
transaction that, as described in a "no-action" or interpretive letter from
the Staff of the Securities and Exchange Commission (the "SEC"), is not
required to be registered under the Act.

                  In the event of a sale or other disposition by the undersigned
of Shares pursuant to Rule 145(d)(1), the undersigned will supply Parent with
evidence of compliance with such Rule, in the form of a letter in the form of
Annex A hereto. The undersigned understands that Parent may instruct its
transfer agent to withhold the transfer of any Shares disposed of by the
undersigned, but that upon receipt of such evidence of compliance the transfer
agent shall effectuate the transfer of the Shares sold as indicated in the
letter.

                  The undersigned acknowledges and agrees that appropriate
legends will be placed on certificates representing Shares received by the
undersigned in the Merger or held by a transferee thereof, which legends will be
removed by delivery of substitute certificates upon receipt of an opinion in
form and substance reasonably satisfactory to Parent from independent counsel
reasonably satisfactory to Parent to the effect that such legends are no longer
required for the purposes of the Act or the third paragraph of this letter.

                  The undersigned acknowledges that (i) the undersigned has
carefully read this letter and understands the requirements hereof and the
limitations imposed upon the distribution, sale, transfer or other disposition
of Shares and (ii) the receipt by Parent of this letter is an inducement and a
condition to Parent's obligations to consummate the Merger.

                                            Very truly yours,

                  On _____________ the undersigned sold _____________ Shares
(the "Shares"), of Biovail Corporation International (the "Parent"). The Shares
were received by the undersigned in connection with the merger of a direct
wholly owned subsidiary of Parent with and into Fuisz Technologies Ltd.

                  Based upon the most recent report or statement filed by the
Parent with the Securities and Exchange Commission, the Shares sold by the
undersigned were within the prescribed limitations set forth in paragraph (e) of
Rule 144 promulgated under the Securities Act of 1933, as amended (the "Act").

                  The undersigned hereby represents that the Shares were sold in
"brokers' transactions" within the meaning of Section 4(4) of the Act or in
transactions directly with a "market maker" as that term is defined in Section
3(a)(38) of the Securities Exchange Act of 1934, as amended. The undersigned
further represents that the undersigned has not solicited or arranged for the
solicitation of orders to buy the Shares, and that the undersigned has not made
any payment in connection with the offer or sale of the Shares to any person
other than to the broker who executed the order in respect of such sale.


                                            Very truly yours,

Re: Consulting Agreement


Dear Dr. Fuisz:

We refer to the Option Agreement dated July 13, 1999 among Richard C. Fuisz,
M.D., an individual resident in the State of Virginia (the "Consultant"),
Biovail Corporation International, an Ontario Corporation ("Biovail"), and
[Escrow Agent]

The parties agree as follows:

     1.   The Consultant shall provide non-exclusive consulting services to
          Biovail and/or its subsidiaries or affiliates (collectively the
          "Company") from time to time during the Term (as defined below), at
          such times and in such manner that shall be agreed to by each of the
          parties; provided, that the Consultant shall not be obligated to
          provide any specified services or minimum number of days or hours of
          service hereunder or provide services with respect to any particular
          assignment or task.  Prior to the Consultant becoming engaged in
          providing any services hereunder, the Consultant and the Company shall
          meet and confer as to the nature and extent of such services.  Such
          services may include, without limitation, business, strategic and
          marketing advice to the Company's senior executive officers, strategic
          business planning, special projects and other special advice.

     2.   (a) The Company shall pay to the Consultant an amount equal to
          $2,000,000 on the first anniversary of this Agreement; provided that
          if the Company and/or affiliate of the Company has acquired an
          interest of 80% or more, in one or a series of transactions, of the
          equity securities, assets or business of Fuisz Technologies Ltd. on or
          prior to July 13, 2010, the Company shall pay the Consultant an amount
          equal to $500,000 on the last business day of each succeeding March,
          June,

Consulting Agreement

Page 2


          September and December, prorated for partial quarters, for the period
          from the date of acquisition of such 80 percent interest until a total
          of $6,000,000 has been paid under this Section.  Such amounts shall be
          paid by check to the Consultant.  The Consultant, and not the Company,
          shall be individually responsible for paying any withholding taxes and
          other deductions.  In addition, such amounts shall be paid
          irrespective of the disability or death of the Consultant during
          the Term (in the event of such death, such amounts shall be paid to
          the Consultant's estate or designated beneficiaries).  The amounts
          described above shall be in full consideration of any and all
          consulting services provided by the Consultant during the Term.  The
          Company shall have the right to terminate this letter agreement at any
          time, upon five days' prior notice to the Consultant; provided, that
          in the event of such termination, the Company shall continue to be
          liable for the payments described above to the Consultant at the time
          and in the amounts set forth above.

          (b) In the event that the Company requests that the Consultant provide
          consulting services with respect to any particular matter or
          engagement and the Consultant provides such services, the Company
          shall reimburse to the Consultant the Consultant's reasonable and
          actual out-of-pocket costs and expenses in connection therewith upon
          furnishing of proper documentation; provided, that the Consultant
          shall not incur any such cost or expense in excess of $1,000 without
          the prior consent of the Company.

          (c) For the avoidance of doubt, the parties agree that the Company
          shall not be required to provide health, medical or other insurance or
          any other pension, payment or other benefits to the Consultant or his
          family.

     3.   Each of the parties agrees to keep and maintain this letter agreement
          and the transactions contemplated hereby in strict confidence and not
          to disclose this letter agreement, the contents or substance hereof or
          the parties hereto, in each case, without the prior written consent
          of the other party; provided, that the foregoing restrictions on
          disclosure shall not apply to the extent (but solely to the extent)
          required by applicable law or administration or judicial process.  The
          parties acknowledge that this letter agreement may be disclosed if the
          Company acquires an interest in Fuisz Technologies Ltd.

          services involving such business pursuant to the Consulting Agreement.
          The parties acknowledge that Dr. Fuisz is a party to an existing
          consulting agreement with a company which may be viewed as a

          specific assignment.

          (b)  The Consultant shall not, directly or indirectly, during the
          Term or for one year thereafter, request or cause any suppliers or
          customers with whom the Company has a business relationship to
          cancel or terminate any such business relationship with the
          Company.

          (c)  The Consultant shall not, during the Term or for one year
          thereafter, (i) directly or indirectly, solicit, encourage or
          induce in any manner, any current employee of the Company to
          terminate, for any reason, his or her employment with the company
          or (ii) directly or indirectly, hire or offer to hire any former
          employees of the Company or its subsidiaries unless any such
          former employee (A) approaches the Consultant without encouragement
          by the Consultant and (B) such former employee has not been
          employed by the Company for at lease six months at the time of such
          former employee approaching the Consultant.

          (d)  If any portion of the restrictions set forth in this [Section 4]
          should, for any reason whatsoever, be declared invalid by a court of
          competent jurisdiction, the validity or enforceability of the
          remainder of such restrictions shall not thereby be adversely
          affected.

     5.   NON-DISCLOSURE OF CONFIDENTIAL INFORMATION.

          (a)  The Consultant shall not, while this Agreement is in effect or at
          any time following termination of this Agreement, disclose or permit
          to be known (other than as is required in the regular course of his
          duties or required by law (in which case the Consultant shall give the
          company prior written notice of such required disclosure), any
          information acquired by him in the course of his activities on behalf
          of the Company hereunder and known to him to be confidential.  This
          confidentiality obligation shall not apply to any information which
          (I) thereafter becomes publicly available other than pursuant to a
          breach of this [Section 5], directly or indirectly, by the Consultant,

          obligations of confidentiality to the Company.

          (b)  All confidential information and documents relating to the
          Company shall be the exclusive property of the Company.  Upon
          termination of this Agreement, all documents, records, reports,
          writings and other similar documents containing confidential
          information, including copies thereof, then in the Consultant's

          acquired or written, by the consultant, solely or jointly with others
          in the course of rendering the services to be provided hereunder on
          behalf of the Company hereunder (collectively the "Subject Matter").

          (b)  The Consultant hereby agrees to assign and transfer to the
          company all his rights, title and interest in and to the Subject

          applications for copyrights or patents, as may be necessary to
          obtain copyrights and patents for any thereof in any and all countries
          and to vest title thereto to the Company.

     7.   In the event that the Company requests that the Consultant provide
          services hereunder to the Company or its subsidiaries or affiliates,
          and the Consultant provides such services, the parties agree that the
          Company will indemnify and hold harmless the Consultant from and
