                                MERGER AGREEMENT

         THIS MERGER AGREEMENT (this "Agreement") dated as of October 30, 2000,
is among CHESAPEAKE BIOLOGICAL LABORATORIES, INC., a Maryland corporation
("Company"), CANGENE CORPORATION, a Canadian corporation ("Parent"), and AC
ACQUISITION SUBSIDIARY, INC., a Maryland corporation and a wholly owned, direct
subsidiary of Parent ("Acquisition").

         WHEREAS, the Board of Directors of the Company (the "Board") has, in
light of and subject to the terms and conditions set forth herein, (i)
determined that each of the Offer and the Merger (each as defined below) is
advisable and is fair to the stockholders of the Company and in the best
interests of such stockholders; (ii) approved and adopted this Agreement and the
transactions contemplated hereby; and (iii) resolved to recommend acceptance of
the Offer and approval and adoption by the stockholders of the Company, if
necessary, of this Agreement;

         WHEREAS, in furtherance thereof, Acquisition shall promptly commence a
tender offer (the "Offer") to acquire all of the issued and outstanding Shares
(defined in Section 3.2(a)), together with all of the issued and outstanding
shares of the Company's Series A-1 Convertible Preferred Stock (the "Convertible
Preferred Stock") and warrants to purchase Shares (the "Warrants"), at a price
of $4.60 per Share (such amount, as it may be increased from time to time in
connection with the Offer, being hereinafter referred to as the "Per Share
Amount"), net to the seller in cash, less any required withholding of taxes, in
accordance with the terms and subject to the conditions provided herein; and

         WHEREAS, as a condition of and inducement to Parent's and Acquisition's
entering into this Agreement and incurring the obligations set forth herein,
certain stockholders of the Company concurrently herewith are entering into a
stockholders' agreement (the "Stockholders' Agreement") dated as of the date
hereof, with Parent and Acquisition, substantially in the form of Exhibit A to
this Agreement.

         NOW THEREFORE, in consideration of the premises and the
representations, warranties, covenants and agreements herein contained and
intending to be legally bound hereby, the Company, Parent and Acquisition hereby
agree as follows.

                                    ARTICLE 1

                                    THE OFFER

         SECTION 1.1. THE OFFER.

         (a) Provided that this Agreement shall not have been terminated in
accordance with Section 8.1 and none of the events or conditions set forth in
Article 6 shall have occurred and be

<PAGE>

existing (unless waived as provided in Article 6), as promptly as practicable
after the date hereof (but in no event later than the twentieth business day
after the public announcement of this Agreement), Acquisition shall commence
(within the meaning of Rule 14d-2 under the Securities Exchange Act of 1934, as
amended (the "Exchange Act"), the Offer. The Offer will be made pursuant to the
Offer Documents (as defined below) containing the terms and conditions set forth
in this Agreement. Acquisition shall accept for payment, purchase and pay for
all Shares, Convertible Preferred Stock and Warrants which have been validly
tendered and not withdrawn pursuant to the Offer at the earliest time following
expiration of the Offer that all conditions to the Offer set forth in Article 6
shall have been satisfied or waived by Acquisition. The obligation of
Acquisition to accept for payment, purchase and pay for Shares, Convertible
Preferred Stock and Warrants tendered pursuant to the Offer shall be subject
only to the condition that at least a majority of the then issued and
outstanding Shares (giving effect to the conversion of all outstanding shares of
Convertible Preferred Stock and the exercise of all then outstanding Warrants)
be validly tendered (the "Minimum Condition") and the satisfaction of the other
conditions set forth in Article 6. Acquisition expressly reserves the right to
waive any such condition (other than the Minimum Condition), to increase the
price per Share payable in the Offer or to make any other changes in the terms
and conditions of the Offer (provided that, unless previously approved by the
Company in writing, no change may be made which decreases the Per Share Amount,
which reduces the number of Shares to be purchased in the Offer, which changes
the form of consideration to be paid in the Offer, which imposes conditions to
the Offer in addition to those set forth in Article 6 or which amends or changes
any term or condition of the Offer in a manner adverse to the holders of
Shares). In the case of shares of Convertible Preferred Stock tendered pursuant
to the Offer, Acquisition shall pay the Per Share Amount multiplied by the
number of Shares into which such Shares of Convertible Preferred Stock are then
convertible. In the case of Warrants tendered pursuant to the Offer, Acquisition
shall purchase such Warrants for a purchase price equal to the difference
between the exercise price thereof and the Per Share Amount, multiplied by the
number of Shares for which such Warrants are then exercisable. The Per Share
Amount shall be paid net to each seller in cash, less any required withholding
of taxes, upon the terms and subject to the conditions of the Offer. The Company
agrees that no Shares held by the Company or any of its subsidiaries will be
tendered in the Offer.

         (b) Subject to the terms and conditions thereof, the Offer shall expire
at midnight, New York City time, on January 3, 2001 (the "Initial Expiration
Date"); provided, however, without the consent of the Board, Parent may cause
Acquisition to (i) from time to time extend the Offer, if at the Initial
Expiration Date of the Offer, any of the conditions to the Offer necessary to
consummate the Offer have not been satisfied or waived (other than the Minimum
Condition, to which this clause (i) does not apply), until such time as such
conditions are satisfied or waived; (ii) extend the Offer for any period
required by any applicable rule, regulation, interpretation or position of the
Securities and Exchange Commission (the "SEC") or the staff thereof; (iii) if
the Minimum Condition is not satisfied, extend the Offer; provided that all
extensions pursuant to clauses (i) through (iii) hereof shall not exceed twenty
(20) business days, and (iv) if the Minimum Condition is satisfied but the
number of Shares validly tendered and not withdrawn represents less than ninety
percent (90%) of the then outstanding Shares

                                       -2-
<PAGE>

(giving effect to the conversion of all then outstanding shares of Convertible
Preferred Stock and the exercise of all then outstanding Warrants), after
consummation of the Offer and payment for all validly tendered shares, commence
one subsequent offer for the Shares provided that Acquisition shall meet the
requirements of Rule 14d-11 under the Exchange Act in connection with such
subsequent offer; provided however, that in no event shall any such subsequent
offer period exceed twenty (20) business days. In addition, Parent and
Acquisition agree that Acquisition shall from time to time extend the Offer if
requested by the Company, if, at the Initial Expiration Date (or any extended
expiration date of the Offer, if applicable), any of the conditions to the Offer
including the Minimum Condition shall not have been waived or satisfied, until
(taking into account all such extensions) February 28, 2001, provided, however,
that if the Minimum Condition is the only condition to the Offer not then
satisfied, Acquisition shall not be required to extend the Offer for more than
twenty (20) business days.

         (c) As soon as practicable after the date of commencement of the Offer,
Acquisition shall file with the SEC a Tender Offer Statement on Schedule TO with
respect to the Offer, which shall include an offer to purchase and form of
transmittal letter (together with any amendments thereof or supplements thereto,
collectively the "Offer Documents"). The Offer Documents shall comply in all
material respects with the provisions of applicable federal securities laws and
the rules and regulations of the SEC. Parent, Acquisition and the Company each
agrees promptly to correct any information provided by it for use in the Offer
Documents if and to the extent that such information shall have become false or
misleading in any material respect, and Acquisition further agrees to take all
steps necessary to cause the Offer Documents as so corrected to be promptly
filed with the SEC and to be disseminated to holders of Shares, in each case as
and to the extent required by applicable federal securities laws and the rules
and regulations of the SEC. The Company and its counsel shall be given a
reasonable opportunity to review and comment on the Offer Documents prior to
their being filed with the SEC. Parent and Acquisition agree to provide to the
Company and its counsel any comments or other communications which Parent,
Acquisition or their counsel receives from the staff of the SEC with respect to
the Offer Documents promptly after receipt thereof.

         SECTION 1.2. COMPANY ACTION.

         (a) The Company hereby approves of and consents to the Offer and the
Merger and represents and warrants that the Board, including all of the
independent directors of the Company, at a meeting duly called and held on
October 12, 2000, has, subject to the terms and conditions set forth herein,
adopted resolutions, which are not conditional and have not been amended or
repealed, pursuant to which the Board has (i) determined that this Agreement and
the transactions contemplated hereby, including the Offer and the Merger, are
fair to, and in the best interests of, the stockholders of the Company, (ii)
declared that the Merger is advisable and approved this Agreement and the
transactions contemplated hereby, including the Offer and the Merger, in all
respects and such approval constitutes prior approval of the Offer, this
Agreement and the Merger for purposes of Section 3-105(b) of the Maryland
General Corporation Law (the "MGCL") and similar provisions of any other similar
state statutes that might be deemed

                                       -3-
<PAGE>

applicable to the transactions contemplated hereby, (iii) recommended that the
stockholders of the Company accept the Offer, tender their Shares thereunder to
Acquisition and, if required by law, approve and adopt this Agreement and the
Merger; and in addition that the Company consents, subject to Section 5.4, to
the inclusion of such recommendation and approval in the Offer Documents, (iv)
agreed to take all actions to amend the Option Plans in the manner contemplated
by this Agreement, (v) caused the transactions contemplated by this Agreement
not to be governed by the provisions of Subtitles 6 and 7 of Title 3 of the
MGCL, and (v) approved the Option Agreement (as hereinafter defined), authorized
the classification of the Series B Preferred Stock (as hereinafter defined), the
filing of Articles Supplementary with respect to the Series B Preferred Stock
and the issuance of the Series B Preferred Stock to Acquisition upon exercise of
the Option in the manner described in the Option Agreement.

         (b) The Company hereby agrees to file with the SEC as soon as
practicable after the date hereof a Solicitation/Recommendation Statement on
Schedule 14D-9 pertaining to the Offer (together with any amendments thereof or
supplements thereto, the "Schedule 14D-9"), containing the recommendation
described in Section 1.2(a) and to promptly mail the Schedule 14D-9 to the
stockholders of the Company. The Company, Parent and Acquisition each agrees
promptly to correct any information provided by it for use in the Schedule 14D-9
if and to the extent that such information 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 promptly filed with
the SEC and disseminated to the holders of Shares, in each case as and to the
extent required by applicable federal securities laws and the rules and
regulations of the SEC. The Parent, Acquisition and their counsel shall be given
a reasonable opportunity to review and comment on the Schedule 14D-9 prior to it
being filed with the SEC. The Company agrees to provide to Parent, Acquisition
and their counsel any comments or other communications which the Company or its
counsel receives from the staff of the SEC with respect to the Schedule 14D-9
promptly after receipt thereof. Notwithstanding anything to the contrary in this
Agreement, the Board may withdraw, modify or amend its recommendation under the
circumstances set forth in Section 5.4.

         (c) In connection with the Offer, the Company will promptly furnish
Parent and Acquisition with mailing labels, security position listings and any
available listing or computer files containing the names and addresses of the
record holders of the Shares as of a recent date and shall furnish Acquisition
with such additional information and assistance (including, without limitation,
updated lists of stockholders, mailing labels and lists of securities positions)
as Acquisition or its agents may reasonably request to facilitate communicating
the Offer to the record and beneficial holders of Shares. Subject to the
requirements of applicable law, and except for such steps as are necessary to
disseminate the Offer Documents and any other documents necessary to consummate
the Merger, Parent, Acquisition and their affiliates, associates, agents and
advisors shall use the information contained in any such labels, listings and
files only in connection with the Offer and the Merger, and, if this Agreement
shall be terminated, will deliver to the Company all copies of such information
then in their possession.

                                       -4-
<PAGE>

         (d) Immediately prior to Acquisition's commencement of the Offer, the
Company shall grant Acquisition an option (the "Option") to purchase from the
Company authorized but unissued shares of Series B Preferred Stock pursuant to
an option agreement substantially in the form attached as Exhibit B to this
Agreement (the "Option Agreement"); provided, however, that the exercise of the
Option shall be subject to the approval of the stockholders of the Company if
counsel to the Company reasonably determines that such approval is required as a
condition of the continued listing of the Shares on the Nasdaq National Market
at any time prior to Acquisition's exercise of the Option. The Series B
Preferred Stock shall be entitled to vote together with the Shares as a single
class on the Merger and any other matter to be voted upon by the Shares and
shall entitle each holder of the Series B Preferred Stock to 1,000 votes for
each share of Series B Preferred Stock held. The Option Agreement shall grant
Acquisition the right to purchase that number of shares of Series B Preferred
Stock that will cause Acquisition to own shares of the Company's capital stock
representing at least ninety percent (90%) of the total number of votes entitled
to vote on the Merger immediately following the exercise of the Option. The
Option shall be exercisable only when and if Acquisition has, pursuant to the
Offer, purchased and paid for a sufficient number of Shares to satisfy the
Minimum Condition. The Option shall terminate and expire, if not previously
exercised, simultaneously with the earlier of (i) Acquisition's termination of
the Offer without having purchased and paid for a sufficient number of Shares to
satisfy the Minimum Condition or (ii) termination of this Agreement in
accordance with Section 8.1. The exercise price of the Option shall be
$2,500,000 for all of the shares of Series B Preferred Stock to be purchased.

         (e) In order to enable Acquisition's exercise of the Option,
immediately after Acquisition has, pursuant to the Offer, purchased and paid for
a sufficient number of Shares to satisfy the Minimum Condition, the Company
shall file Articles Supplementary with the SDAT containing the rights,
preferences and powers of the Series B Preferred Stock.

         SECTION 1.3. BOARDS OF DIRECTORS AND COMMITTEES; SECTION 14(F).

         (a) Beginning immediately after the purchase by Acquisition of Shares
pursuant to the Offer following the Initial Expiration Date or, if applicable,
the extended expiration date of the Offer (the "Tender Offer Purchase Time") and
from time to time thereafter, and subject to the last sentence of this Section
1.3(a), Acquisition shall be entitled to designate that number (but no more than
that number) of directors of the Company that would constitute a majority of the
Board, and the Company shall use its best efforts to, upon request by
Acquisition, promptly, at the Company's election, either increase the size of
the Board or secure the resignation of such number of directors as is necessary
to enable Acquisition's designees to be elected to the Board and to cause
Acquisition's designees to be so elected and to constitute at all times after
the Tender Offer Purchase Time a majority of the Board. At such times, and
subject to the last sentence of this Section 1.3(a), the Company will use its
best efforts to cause persons designated by Acquisition to constitute the same
percentage as is on the Board of (i) each committee of the Board (other than any
committee of the Board established to take action under this Agreement), (ii)
each board of directors of each subsidiary of the Company and (iii) each
committee of each

                                      -5-
<PAGE>

such board. Notwithstanding the foregoing, until the Effective Time (as defined
in Section 2.3 hereof) the Company shall retain at least three directors who are
directors of the Company on the date hereof (the "Continuing Directors").

         (b) The Company's obligation to appoint designees to the Board shall be
subject to Section 14(f) of the Exchange Act and Rule 14f-1 promulgated
thereunder. The Company shall promptly take all action required pursuant to such
Section and Rule in order to fulfill its obligations under this Section 1.3 and
shall include in the Schedule 14D-9 such information with respect to the Company
and its officers and directors as is required under such Section and Rule in
order to fulfill its obligations under this Section 1.3. Acquisition will supply
to the Company in writing and be solely responsible for any information with
respect to itself and its nominees, officers, directors and affiliates required
by such Section and Rule.

         (c) From and after the time, if any, that Acquisition's designees
constitute a majority of the Board until the Effective Time, any amendment,
modification or waiver of any term or condition of this Agreement or the Option
Agreement, any amendment or modification to the Articles of Incorporation or
By-Laws of the Company, any termination of this Agreement by the Company, any
extension of time of performance of any of the obligations of Parent or
Acquisition hereunder, any waiver of any condition or any of the Company's
rights hereunder or other action by the Company in connection with the rights of
the Company hereunder may be effected only with the approval of a majority of
the Continuing Directors.

                                    ARTICLE 2

                                   THE MERGER

         SECTION 2.1. THE MERGER. At the Effective Time and upon the terms and
subject to the conditions of this Agreement and in accordance with the MGCL,
Acquisition shall be merged with and into the Company (the "Merger"). Following
the Merger, the Company shall continue as the surviving corporation (the
"Surviving Corporation") and the separate corporate existence of Acquisition
shall cease. Parent, as the sole stockholder of Acquisition, hereby approves
this Agreement, the Merger and the other transactions contemplated hereby.
Subject to the terms and conditions of this Agreement, Parent and Acquisition
agree to cause the Effective Time to occur as soon as practicable after the
Stockholders' Meeting (as defined in Section 5.2(a)) or Acquisition's purchase
and payment for shares of the capital stock of the Company representing not less
than ninety percent (90%) of the votes entitled to be cast on the Merger
pursuant to the Offer and the Option.

         SECTION 2.2. CLOSING OF THE MERGER. The closing of the Merger will take
place at a time (the "Closing Time") and on a date to be specified by the
parties, which shall be no later than the second business day after satisfaction
or waiver (in accordance with this Agreement) of the latest to occur of the
conditions set forth in Article 7 (other than those conditions that, by their
nature, are to be satisfied at the Closing Time, but subject to the satisfaction
or waiver of

                                      -6-
<PAGE>

those conditions) at the offices of Hartman & Craven LLP, 460 Park Avenue, New
York, New York 10022, unless another time, date or place is agreed to in writing
by the parties hereto.

         SECTION 2.3. EFFECTIVE TIME. Subject to the terms and conditions set
forth in this Agreement, Articles of Merger (the "Merger Certificate") shall be
duly executed and acknowledged by Acquisition and the Company and thereafter
delivered at the Closing Time to the State Department of Assessments and
Taxation ("SDAT") of the State of Maryland for filing pursuant to the MGCL. The
Merger shall become effective at such time as a properly executed Merger
Certificate is duly accepted by the SDAT for filing pursuant to the MGCL, or
such later time as Acquisition and the Company may agree upon and set forth in
the Merger Certificate (not exceeding 30 days after the Merger Certificate is
accepted for record; the time the Merger becomes effective being referred to
herein as the "Effective Time").

         SECTION 2.4. EFFECTS OF THE MERGER. The Merger shall have the effects
set forth in the MGCL. Without limiting the generality of the foregoing and
subject thereto, at the Effective Time, all the properties, rights, privileges,
powers and franchises of the Company and Acquisition shall vest in the Surviving
Corporation and all debts, liabilities and duties of the Company and Acquisition
shall become the debts, liabilities and duties of the Surviving Corporation.

         SECTION 2.5. ARTICLES OF INCORPORATION AND BYLAWS. The Articles of
Incorporation of Acquisition in effect at the Effective Time shall be the
Articles of Incorporation of the Surviving Corporation until amended in
accordance with applicable law. The Bylaws of Acquisition in effect at the
Effective Time shall be the Bylaws of the Surviving Corporation until amended in
accordance with applicable law.

         SECTION 2.6. DIRECTORS. The directors of Acquisition at the Effective
Time shall be the initial directors of the Surviving Corporation, each to hold
office in accordance with the Articles of Incorporation and Bylaws of the
Surviving Corporation until the next annual meeting of stockholders and until
each such director's successor is duly elected or appointed and qualified;
provided, however, that immediately following the Merger, the Board of Directors
of the Surviving Corporation shall cause Thomas P. Rice to be elected a director
of the Surviving Corporation.

         SECTION 2.7. OFFICERS. The officers of the Company at the Effective
Time shall be the initial officers of the Surviving Corporation, each to hold
office in accordance with the Articles of Incorporation and Bylaws of the
Surviving Corporation until such officer's successor is duly elected or
appointed and qualified.

         SECTION 2.8. CONVERSION OF SHARES AND CONVERTIBLE PREFERRED STOCK.

         (a) At the Effective Time, each Share issued and outstanding
immediately prior to the Effective Time (excluding (i) any Shares held by any of
the Company's subsidiaries and (ii) any

                                      -7-
<PAGE>

Shares held by Parent, Acquisition or any other subsidiary of Parent) shall, by
virtue of the Merger and without any action on the part of Acquisition, the
Company or the holder thereof, be converted into and shall become the right to
receive the Per Share Amount in cash, without interest (the "Cash Merger
Consideration"). At the Effective Time, each share of Convertible Preferred
Stock issued and outstanding immediately prior to the Effective Time (excluding
(i) any shares of Convertible Preferred Stock held by any of the Company's
subsidiaries and (ii) any shares of Convertible Preferred Stock held by Parent,
Acquisition or any other subsidiary of Parent) shall, by virtue of the Merger
and without any action on the part of Acquisition, the Company or the holder
thereof, be converted into and shall become the right to receive the Cash Merger
Consideration multiplied by the number of Shares into which such share of
Convertible Preferred Stock is then convertible. Notwithstanding the foregoing,
if between the date of this Agreement and the Effective Time, the Shares shall
have been changed into a different number of shares or a different class by
reason of any stock dividend, subdivision, reclassification, recapitalization,
split, combination or exchange of shares, then the Cash Merger Consideration
contemplated by the Merger shall be correspondingly adjusted to reflect such
stock dividend, subdivision, reclassification, recapitalization, split,
combination or exchange of shares.

         (b) At the Effective Time, any outstanding Company options (other than
stock options granted by the Company to employees, directors, officers or
consultants), warrants, convertible preferred stock (other than the Convertible
Preferred Stock) or other securities (collectively, the "Convertible
Securities") that are convertible into, exercisable for or exchangeable for
Shares and by their terms are not automatically converted into, exercised for or
exchanged for the right to receive the Cash Merger Consideration as a result of
the Merger shall thereafter represent only the right to receive the Cash Merger
Consideration (minus any cash exercise or exchange price). In furtherance of the
preceding sentence, the Company agrees to take all reasonable action to cause
the terms of any such securities to provide for such conversion, exercise or
exchange into the Cash Merger Consideration, including reasonable efforts to
obtain the consent of the holders of any such Convertible Securities to
agreements to amend the terms thereof to provide for such conversion, exercise
or exchange.

         (c) At the Effective Time, each Share and each share of Series B
Preferred Stock held by Parent, Acquisition or any subsidiary of Parent,
Acquisition or the Company immediately prior to the Effective Time shall, by
virtue of the Merger and without any action on the part of Acquisition, the
Company or the holder thereof, be canceled and retired and will cease to exist
and no payment shall be made with respect thereto.

         (d) At the Effective Time, each share of common stock of Acquisition
issued and outstanding immediately prior to the Effective Time shall be
converted into and shall become one validly issued, fully paid and nonassessable
share of common stock of the Surviving Corporation.

         SECTION 2.9. PAYMENT OF CASH MERGER CONSIDERATION.

                                      -8-
<PAGE>

         (a) As of the Effective Time, Acquisition shall deposit in trust with
such agent or agents as may be appointed by Parent and Acquisition and
reasonably acceptable to the Company (the "Payment Agent") for the benefit of
the holders of issued and outstanding Shares, the Convertible Preferred Stock
and the Convertible Securities at the Effective Time (excluding (i) Shares held
by any of the Company's subsidiaries and (ii) Shares or shares of Series B
Preferred Stock held by Parent, Acquisition or any other subsidiary of Parent),
an amount in cash equal to the aggregate amount necessary to pay the Cash Merger
Consideration, together with an amount of cash sufficient to pay for the
settlement of each Company Stock Option as described in Section 2.10(b) hereof
(such cash is hereinafter referred to as the "Merger Fund") payable pursuant to
Section 2.8 and in settlement of each Company Stock Option pursuant to Section
2.10(b) in exchange for such issued and outstanding Shares. The Payment Agent
shall, pursuant to irrevocable instructions, deliver the Cash Merger
Consideration out of the Merger Fund only as provided in this Section 2.9. The
Merger Fund shall not be used for any other purpose.

         (b) As soon as reasonably practicable after the Effective Time, Parent
shall cause the Payment Agent to mail to each holder of record of a certificate
or certificates which immediately prior to the Effective Time represented issued
and outstanding Shares, Convertible Preferred Stock or Convertible Securities
(the "Certificates") that were converted into the right to receive the Cash
Merger Consideration pursuant to Section 2.8: (i) a letter of transmittal (which
shall specify that delivery shall be effected and risk of loss and title to the
Certificates shall pass only upon delivery of the Certificates to the Payment
Agent and shall be in such form and have such other provisions as Parent and the
Company may reasonably specify) and (ii) instructions on how to surrender the
Certificates in exchange for the Cash Merger Consideration. Upon surrender to
the Payment Agent of a Certificate for cancellation, together with such letter
of transmittal duly executed, the holder of such Certificate shall be entitled
to receive in exchange therefor, and Parent shall cause the Payment Agent to
deliver, a check representing the Cash Merger Consideration (less the exercise
price, if any, of any Convertible Securities so surrendered) which such holder
has the right to receive pursuant to the provisions of this Article 2, and the
Certificate so surrendered shall forthwith be canceled. In the event of a
transfer of ownership of Shares, Convertible Preferred Stock or Convertible
Securities which is not registered in the transfer records of the Company,
payment of the Cash Merger Consideration may be made to a transferee if the
Certificate representing such Shares, Convertible Preferred Stock or Convertible
Securities is presented to the Payment 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 2.9, each Certificate shall be deemed at all times
and for all purposes after the Effective Time to represent only the right to
receive upon such surrender the Cash Merger Consideration as contemplated by
this Section 2.9.

         (c) In the event that any Certificate shall have been lost, stolen or
destroyed, Parent shall cause the Payment Agent to issue in exchange therefor,
upon the making of an affidavit of that fact by the holder thereof, such Cash
Merger Consideration as may be required pursuant to this Agreement; provided,
however, that Acquisition or the Payment Agent may, in its discretion, require
the delivery of a suitable bond or indemnity.

                                      -9-
<PAGE>

         (d) All Cash Merger Consideration paid upon the surrender for exchange
of Shares, Convertible Preferred Stock or Convertible Securities in accordance
with the terms hereof shall be deemed to have been paid in full satisfaction of
all rights pertaining to such Shares, Convertible Preferred Stock or Convertible
Securities; subject, however, to the Surviving Corporation's obligation to pay
any dividends or make any other distributions with a record date prior to the
Effective Time which may have been declared or made by the Company on such
Shares, Convertible Preferred Stock or Convertible Securities in accordance with
the terms of this Agreement, or prior to the date hereof and which remain unpaid
at the Effective Time. After the Effective Time, there shall be no further
registration of transfers on the stock transfer books of the Surviving
Corporation of the Shares, Convertible Preferred Stock or Convertible Securities
which were outstanding immediately prior to the Effective Time. If after the
Effective Time, Certificates are presented to the Surviving Corporation for any
reason they shall be canceled and exchanged as provided in this Article 2.

         (e) Any portion of the Merger Fund which remains undistributed to the
stockholders of the Company for six months after the Effective Time shall be
delivered to Parent upon demand, and any stockholders of the Company who have
not theretofore complied with this Article 2 shall thereafter look only to
Parent for payment of their claim for any portion of the Cash Merger
Consideration.

         (f) Neither Acquisition nor the Company shall be liable to any holder
of Shares, Convertible Preferred Stock or Convertible Securities for cash from
the Merger Fund delivered to a public official pursuant to any applicable
abandoned property, escheat or similar law.

         SECTION 2.10. STOCK OPTIONS.

         (a) At the Effective Time, each then outstanding option to purchase
Shares (a "Company Stock Option" or collectively "Company Stock Options") issued
pursuant to the Company's Second Incentive Stock Option Plan, Third Incentive
Stock Option Plan, Fourth Incentive Stock Option Plan, Fifth Stock Incentive
Plan and 1997 Directors' Stock Option Plan or otherwise issued to any employee,
officer, director, consultant or former employee, officer, director or
consultant (collectively, the "Option Plans"), whether vested or unvested, the
exercise price of which is greater than the Cash Merger Consideration, shall be
canceled and extinguished without consideration, and the Option Plans shall
terminate as of the Effective Date.

         (b) At the Effective Time, each then outstanding Company Stock Option
issued pursuant to the Option Plans that is vested as of the Effective Time, the
exercise price of which is less than the Cash Merger Consideration shall be
canceled and extinguished and shall become the right to receive an amount,
without interest, in cash paid at the Effective Time equal to the excess, if any
of the Cash Merger Consideration over the exercise price per Share of such
Company Stock Option, less the amount of Taxes (as defined in Section 3.13(a))
required to be withheld under applicable Federal, state or local laws and
regulations, multiplied by the number

                                      -10-
<PAGE>

of Shares subject to such Company Stock Option, payable in accordance with the
provisions of Section 2.9 of this Agreement.

         (c) At the Effective Time, each then outstanding Company Stock Option
issued pursuant to the Option Plans or any other stock option plan, program,
arrangement or agreement to which the Company or any of its subsidiaries is a
party that is not vested as of the Effective Time, the exercise price of which
is less than the Cash Merger Consideration shall be canceled and extinguished in
consideration for a compensatory payment to be paid to the holder of such option
at the time such option would otherwise have vested (provided that such holder
is employed with the Company at such time of vesting and has not breached any of
such holder's obligations under any applicable employment agreement with the
Company or any Subsidiary) equal to an amount, without interest, in cash equal
to the excess, if any of the Cash Merger Consideration over the exercise price
per Share of such options that would otherwise have vested at such time.
Notwithstanding the foregoing, the right to receive such payments shall vest in
accordance with the terms of the applicable option agreement.

         (d) If and to the extent required by the terms of the Option Plans, or
any other stock option plan, program, arrangement or agreement to which the
Company or any of its subsidiaries is a party or the terms of any option granted
thereunder, the Company shall cooperate with Parent and Acquisition in obtaining
the consent of each holder of outstanding Company Stock Options to the foregoing
treatment of such options and to take any other action necessary to effect the
foregoing provisions.

                                    ARTICLE 3

                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

         Except as set forth in the Disclosure Schedule previously delivered by
the Company to Parent (the "Company Disclosure Schedule"), the Company hereby
represents and warrants to each of Parent and Acquisition as of the date hereof
as follows:

         SECTION 3.1. ORGANIZATION AND QUALIFICATION; SUBSIDIARIES.

         (a) Each of the Company and each of its subsidiaries is duly organized,
validly existing and in good standing under the laws of the jurisdiction of its
incorporation or organization, except where the failure to qualify or to be in
good standing would not have a Material Adverse Effect (as defined below) and
has all requisite power and authority to own lease and operate its properties
and to carry on its businesses as now being conducted, except where the failure
to have such power and authority would not have a Material Adverse Effect. The
Company has heretofore made available to Parent complete and correct copies of
the Articles of Incorporation and Bylaws (or similar governing documents), as
currently in effect, of the Company and each of its subsidiaries. When used in
connection with the Company or its subsidiaries, the term

                                      -11-
<PAGE>

"Material Adverse Effect" means any change or effect (i) that is materially
adverse to the business, properties, financial condition, or results of
operations of the Company and its subsidiaries, taken as whole, or (ii) that
would materially impair the ability of the Company to perform its obligations
hereunder. Notwithstanding the foregoing, none of the following shall be deemed,
either alone or in combination, to constitute a Material Adverse Effect: (i)
changes or effects resulting from general changes in economic, market,
regulatory or political conditions or changes in conditions or business
practices generally applicable to the industries in which the Company and its
subsidiaries operate; (ii) changes in the market price or trading volume of the
Shares on the Nasdaq National Market or the delisting of the Shares on the
Nasdaq National Market; or (iii) changes or effects resulting from the
announcement or approval of the Offer and the Agreement or relating to the
identity of or facts pertaining to Parent or Acquisition.

         (b) Each of the Company and its subsidiaries is duly qualified or
licensed and in good standing to do business in each jurisdiction in which the
property owned, leased or operated by it or the nature of the business conducted
by it makes such qualification or licensing necessary, except in such
jurisdictions where the failure to be so duly qualified or licensed and in good
standing would not have a Material Adverse Effect on the Company.

         SECTION 3.2. CAPITALIZATION OF THE COMPANY AND ITS SUBSIDIARIES.

         (a) The authorized stock of the Company consists of 14,984,490 shares
of Class A common stock, par value $.01 per share (the "Shares"), of which, as
of September 30, 2000, 5,681,156 Shares were issued and outstanding, and 15,510
shares of Series A-1 convertible preferred stock, par value $.01 per share (the
"Convertible Preferred Stock"), of which, as of September 30, 2000, 14,511
shares were outstanding. All of the outstanding Shares have been validly issued
and are fully paid and nonassessable, and free of preemptive rights granted by
the Company. As of September 30, 2000, (i) 1,515,338 were reserved for issuance
upon the exercise of outstanding Company Stock Options issued pursuant to the
Option Plans and other stock option plans, or agreements to which the Company or
any of its subsidiaries is a party, (ii) 967,448 Shares were reserved for
issuance upon the conversion of the outstanding Convertible Preferred Stock, and
(iii) 123,370 Shares were reserved for issuance upon the exercise of the
outstanding Warrants. Except as set forth in Section 3.2(a) of the Company
Disclosure Schedule, since September 30, 2000, no shares of the Company's stock
have been issued other than pursuant to Company Stock Options or other
stock-based employee benefit plans of the Company and no options to acquire
Shares have been granted other than pursuant to the Option Plans. Except as set
forth above and in Section 3.2(a) of the Company Disclosure Schedule, as of the
date hereof, there are issued, reserved for issuance, or outstanding (i) no
shares of stock or other voting securities of the Company, (ii) no securities of
the Company or its subsidiaries convertible into or exchangeable for shares of
stock or voting securities of the Company, (iii) no options or other rights to
acquire from the Company or its subsidiaries and, except for the Series B
Preferred Stock issuable upon exercise of the Option or as described in Section
3.2(a) of the Company Disclosure Schedule, no obligations of the Company or its
subsidiaries to issue any stock, voting securities or securities convertible
into or exchangeable for stock or voting

                                      -12-
<PAGE>

securities of the Company, (iv) no bonds, debentures, notes or other
indebtedness or obligations of the Company or any of its subsidiaries entitling
the holders thereof to have the right to vote (or which are convertible into, or
exercisable or exchangeable for, securities entitling the holders thereof to
have the right to vote) with the stockholders of the Company or any of its
subsidiaries on any matter, and (v) no equity equivalent interests in the
ownership or earnings of the Company or its subsidiaries or other similar rights
(collectively "Company Securities"). As of the date hereof, except as set forth
in Section 3.2(a) of the Company Disclosure Schedule, there are no outstanding
obligations of the Company or its subsidiaries (absolute, contingent or
otherwise) to repurchase, redeem or otherwise acquire any Company Securities.
There are no Shares outstanding subject to rights of first refusal of the
Company, nor are there any pre-emptive rights granted by the Company with
respect to any Shares. Other than this Agreement, there are no stockholder
agreements, voting trusts or other agreements or understandings to which the
Company is a party or by which it is bound relating to the voting or, except as
set forth in Section 3.2(a) of the Company Disclosure Schedule, registration of
any shares of stock of the Company.

         (b) Except as set forth in Section 3.2(b) of the Company Disclosure
Schedule, all of the outstanding stock of the Company's subsidiaries is owned by
the Company, directly or indirectly, free and clear of any Lien (as defined
below). There are no securities of the Company or its subsidiaries convertible
into or exchangeable for, no options or other rights to acquire from the Company
or its subsidiaries and no other contract, understanding, arrangement or
obligation (whether or not contingent) providing for the issuance or sale,
directly or indirectly, of any stock or other ownership interests in, or any
other securities, of any subsidiary of, the Company. Except as set forth in
Section 3.2(b) of the Company Disclosure Schedule, there are no outstanding
contractual obligations of the Company or its subsidiaries to repurchase, redeem
or otherwise acquire any outstanding shares of capital stock or other ownership
interests in any subsidiary of the Company. For purposes of this Agreement,
"Lien" means, with respect to any asset (including without limitation any
security), any mortgage, lien, pledge, charge, security interest or encumbrance
of any kind in respect of such asset (including any restrictions on the right to
vote or sell the same except as may be provided as a matter of law).

         (c) The Shares constitute the only class of equity securities of the
Company or its subsidiaries registered or required to be registered under the
Exchange Act.

         SECTION 3.3. AUTHORITY RELATIVE TO THIS AGREEMENT. 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 and the consummation of the transactions contemplated
hereby have been duly and validly authorized by the Board, and no other
corporate proceedings on the part of the Company are necessary to authorize this
Agreement or to consummate the transactions contemplated hereby except, if
required by law, the approval and adoption of this Agreement and the Merger by
the holders of the outstanding Shares and the filing of the Merger Certificate
with the SDAT, and the filing of Articles Supplementary with respect to the
Series B Preferred Stock. The Board has taken all action necessary under the
MGCL to prevent this Agreement and the transactions contemplated

                                      -13-
<PAGE>

hereby from being governed by the provisions of Subtitles 6 and 7 of Title 3 of
the MGCL. This Agreement has been duly and validly executed and delivered by the
Company and, assuming the due authorization, execution and delivery by Parent
and Acquisition, constitutes a valid, legal and binding agreement of the
Company, enforceable against the Company in accordance with its terms, except as
such enforceability may be limited by any applicable conservator, receivership,
bankruptcy, insolvency, reorganization, moratorium or other similar laws
affecting the enforcement of creditors' rights generally, and except as the
availability of equitable remedies may be limited by the application of general
principles of equity (regardless of whether such equitable principles are
applied in a proceeding at law or in equity).

         SECTION 3.4. SEC REPORTS; FINANCIAL STATEMENTS; ACCOUNTING PROCEDURES.

         (a) The Company has filed all required forms, reports and documents
("Company SEC Reports") with the SEC since March 31, 1999, each of which has
complied (as of its respective date) in all material respects with all
applicable requirements of the Securities Act of 1933, as amended (the
"Securities Act"), and the Exchange Act, each as in effect on the dates such
forms, reports and documents were filed. None of such Company SEC Reports,
including, without limitation, any financial statements or schedules included or
incorporated by reference therein, when filed contained any untrue statement of
a material fact or omitted to state a material fact required to be stated or
incorporated by reference therein or necessary in order to make the statements
therein, in light of the circumstances under which they were made, not
misleading. The audited consolidated financial statements of the Company
included in the Company SEC Reports fairly present in all material respects in
conformity with generally accepted accounting principles in the United States as
in effect from time to time and applied on a consistent basis ("GAAP") (except
as may be indicated in the notes thereto or, in the case of unaudited
consolidated quarterly statements, as permitted by Form 10-Q of the SEC and
subject to normal year-end adjustments) the consolidated financial position of
the Company and its consolidated subsidiaries as of the dates thereof and their
consolidated results of operations and changes in financial position for the
periods then ended.

         (b) The Company has heretofore made available to Acquisition or Parent
a complete and correct copy of all previously filed Company SEC Reports and will
promptly make available to Acquisition or Parent any Company SEC Reports filed
hereafter and any amendments or modifications which are required to be filed
with the SEC but have not yet been filed with the SEC to Company SEC Reports,
including any agreements, documents or other instruments which previously had
been filed by the Company with the SEC pursuant to the Exchange Act.

         (c) The Company and its subsidiaries maintain a system of internal
accounting controls, policies and procedures sufficient to ensure that all
transactions relating to their business are executed in conformity in all
material respects with the applicable rules, regulations, directives and
instructions of governmental and regulatory authorities, and in a manner as to
permit preparation of financial statements to maintain accountability for the
Company's assets.

                                      -14-
<PAGE>

         SECTION 3.5. INFORMATION SUPPLIED. None of the information supplied by
the Company in writing for inclusion or incorporation by reference in the Offer
Documents, Schedule 14D-9, any other tender offer materials, Schedule 14A or
14C, or the proxy statement or information statement ("Proxy Statement")
relating to the Offer or any meeting to be held in connection with the Merger
(all of the foregoing documents, as amended or supplemented, collectively, the
"Disclosure Statements") will, at the date each and any of the Disclosure
Statements is mailed to stockholders of the Company, the date on which any such
document is filed with the SEC and, when applicable, and at the time of the
meeting of stockholders of the Company to be held, if necessary, in connection
with the Merger, 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 therein, in light of the circumstances under which they are
made, not misleading. No representation or warranty is made by the Company with
respect to information supplied in writing by Parent or Acquisition for
inclusion in the Disclosure Statements. The Proxy Statement, if any, filed by
the Company and Schedule 14D-9 will comply as to form in all material respects
with all provisions of applicable law.

         SECTION 3.6. CONSENTS AND APPROVALS; NO VIOLATIONS. Except as set forth
in Section 3.6 of the Company Disclosure Schedule and except for filings,
permits, authorizations, consents and approvals as may be required under, and
other applicable requirements of, (a) the Exchange Act, (b) state securities
laws ("Blue Sky Laws") or take-over laws, (c) the Hart-Scott-Rodino Antitrust
Improvements Act of 1976, as amended (the "HSR Act"), (d) the filing and
recordation and acceptance for record by SDAT of the Articles Supplementary with
respect to the Series B Preferred Stock and Merger Certificate, each as required
by the MGCL, or (e) approval by the Company's lenders and bondholders, no filing
with or notice to, and no permit, authorization, consent or approval of, any
court or tribunal, or administrative governmental or regulatory body, agency or
authority (a "Governmental Entity") is necessary for the execution and delivery
by the Company of this Agreement or the consummation by the Company of the
transactions contemplated hereby, except where the failure to obtain such
permits, authorizations, consents or approvals or to make such filings or give
such notice would not have a Material Adverse Effect. Neither the execution,
delivery and performance of this Agreement by the Company nor the consummation
by the Company of the transactions contemplated hereby will (i) conflict with or
result in any breach of any provision of the respective Articles of
Incorporation or Bylaws (or similar governing documents) of the Company or any
of its subsidiaries, (ii) except as set forth in Section 3.6 of the Company
Disclosure Schedule, result in a violation or breach of or constitute (with or
without due notice or lapse of time or both) a default (or give rise to any
right of termination, amendment, cancellation or acceleration or Lien) under any
of the terms, conditions or provisions of any note, bond, mortgage, indenture,
lease, license, contract, agreement or other instrument or obligation to which
the Company or any of its subsidiaries is a party or by which any of them or any
of their respective properties or assets may be bound or (iii) except as set
forth in Section 3.6 of the Company Disclosure Schedule or in this Section 3.6
violate any order, writ, injunction, decree, law, statute, rule or regulation
applicable to the Company or any of its subsidiaries or any of their respective
properties or assets except, in the case of (ii) or (iii), for violations,
breaches, defaults or rights of termination, amendment, cancellation or
acceleration or

                                      -15-
<PAGE>

Liens which would not have a Material Adverse Effect.

         SECTION 3.7. NO UNDISCLOSED LIABILITIES; ABSENCE OF CHANGES. Except to
the extent publicly disclosed in the Company's SEC Reports, as of March 31,
2000, none of the Company or any of its subsidiaries had any liabilities or
obligations of any nature, whether or not accrued, contingent or otherwise, that
would be required by GAAP to be reflected on a consolidated balance sheet of the
Company and its subsidiaries (including the notes thereto) or which would have a
Material Adverse Effect and since such date, the Company has incurred no such
liability or obligation, which would have a Material Adverse Effect, other than
in the ordinary course of business consistent with past practice.

         SECTION 3.8. LITIGATION; DISPUTES. As of the date hereof (i) there is
no suit, claim, action, proceeding or investigation pending or, to the Company's
Knowledge (as defined below), threatened against the Company or any of its
subsidiaries or any of their respective properties or assets before any
Governmental Entity that individually or in the aggregate would have a Material
Adverse Effect; (ii) none of the Company or its subsidiaries nor any property or
asset of the Company or any of its subsidiaries is subject to any outstanding
order, writ, injunction or decree; and (iii) there is no claim or dispute
between the Company and any customer or supplier and, to the Company's
knowledge, no basis for any such claim or dispute, that individually or in the
aggregate would have a Material Adverse Effect. For purposes of this Agreement,
the term "Knowledge" with respect to the Company means the actual knowledge of
any of the officers and other employees of the Company identified in Exhibit C
hereto.

SECTION 3.9. COMPLIANCE WITH LAWS.

         (a) The Company and its subsidiaries have complied in all material
respects with all applicable laws, rules, regulations, ordinances and codes,
whether federal, state, local or foreign including, without limitation, all laws
and regulations relating to occupational health and safety, equal employment
opportunities, fair employment practices, and sex, race, religious, age and
other prohibited discrimination, and all other labor laws, including without
limitation the Family and Medical Leave Act.

         (b) As to each product subject to the jurisdiction of the Food and Drug
Administration ("FDA") under the Federal Food, Drug and Cosmetic Act, as
amended, and the regulations thereunder ("FDC Act") and the Public Health
Services Act, as amended ("PHS Act"), and the regulations thereunder, and each
product subject to the jurisdiction of the Drug Enforcement Administration
("DEA") under the Controlled Substance Act, as amended, and Controlled
Substances Import and Export Act, as amended ("CS Act") and the regulations
thereunder (each such product, a "Product") that is either manufactured,
packaged, labeled or tested by the Company and its subsidiaries, such Product is
being manufactured, packaged, labeled or tested in compliance with all the
requirements under the FDC Act, PHS Act and the CS Act, and similar laws, rules
and regulations relating to premarket clearance, licensure, or application,
approval, good manufacturing practices, quotas, labeling, record keeping and
filing of reports except where

                                      -16-
<PAGE>

Company. Except as disclosed in the Company SEC Reports or as set forth in
Schedule 3.9(b), since January 1, 1999, neither the Company nor any of its
subsidiaries has received any notice, warning letter or other communication from

controlled substance scheduling of and quotas for, or the labeling and promotion

Products of the Company or any of its subsidiaries have been recalled,
withdrawn, replaced, suspended or discontinued nor have any DEA registrations

Material Adverse Effect on the Company. As to each such application or other
submission that the Company or any subsidiary has submitted to, but not yet
gained approval or the permission from FDA or DEA, the Company has provided all
additional information and taken all additional action reasonably required by
the FDA or DEA in connection with the application or submission. In the
Company's good faith opinion, there are no facts or circumstances that would

submissions to FDA or DEA. As to each such Product, the Company and its
subsidiaries have included in the application for such Product where required,

distributed by the Company or its subsidiaries is not adulterated within the
meaning of 21 U.S.C. (Section) 351 (or similar

laws) or misbranded within the meaning of 21 U.S.C. (Section) 352 (or similar
laws), except where such failure in compliance with the foregoing would not have
a Material Adverse Effect on the Company.

failed to disclose a fact required to be disclosed to the FDA or any other
Governmental Entity, or committed an act, made a statement, or failed to make a
statement that, at the time such disclosure was made could reasonably be
expected to provide a basis for the FDA or any other Governmental Entity to
invoke its policy respecting "Fraud, Untrue Statements of Material Facts,
Bribery, and Illegal Gratuities," set forth in 56 Fed. Reg. 46191 (September 10,
1991) or any similar policy. Neither the Company nor any subsidiary, nor any
officer, employee or agent of the Company or any subsidiary has been convicted
of any crime or engaged in any conduct for which debarment is mandated by 21

initiate, any action to enjoin production at, or suspend or revoke the DEA
registration or any facility of, or enter into a Consent Decree or Permanent
Injunction with the Company or any subsidiary which would have a Material
Adverse Effect on the Company.

         (h) The Company and its subsidiaries, except where the failure be in

operations conducted by or for the benefit of the Company and its subsidiaries

qualification under Section 401(a) (and 401(k) where applicable) of each Company
Employee Plan that is a tax-qualified employee pension benefit plan from the

Employee Plan for which an annual report is required to be filed under ERISA or

and has all requisite power and authority to own, lease and operate its
properties and to carry on its businesses as now being conducted, except in such

any breach of any provision of the respective Articles of Incorporation or

<PAGE>

representatives and agents to, immediately cease any discussions or negotiations
with any parties with respect to any Third Party Acquisition (as defined below).
The Company and its subsidiaries shall and shall direct and use their reasonable
best efforts to cause their respective officers, directors, employees,
representatives or agents not to, directly or indirectly, encourage, solicit,
participate in or initiate discussions or negotiations with or provide any
non-public information to any Person or group (other than Parent and Acquisition
or any designees of Parent and Acquisition) concerning any Third Party
Acquisition; provided, however, that nothing herein shall prevent the Board from
taking and disclosing to the Company's stockholders a position contemplated by
Rules 14d-9 and 14e-2 promulgated under the Exchange Act with regard to any
tender offer; and provided further, that notwithstanding the foregoing, if,
prior to the Tender Offer Purchase Time, the Company receives a "Potential
Proposal" (defined as an unsolicited Superior Proposal (defined below) or an
unsolicited proposal, offer or indication that the Company in good faith
believes may lead to a Superior Proposal), then, following written notice to

making the Potential Proposal with the same non-public information that the

withdraw its recommendation of the transactions contemplated hereby or approve
or recommend, or cause the Company to enter into any agreement with respect to,
any Third Party Acquisition. Notwithstanding the foregoing, if prior to the
Tender Offer Purchase Time, the Board by a majority vote determines in its good
faith judgment, after consultation with its legal counsel, that failure to do so
would be inconsistent with the fiduciary duties of the Board under applicable
law, the Board may withdraw its recommendation of the transactions contemplated
hereby and/or approve or recommend a Superior Proposal; provided, however, that
the Company shall not be entitled to enter into any agreement with respect to a
Superior Proposal unless and until this Agreement is terminated in accordance

interest or investment in any business whose annual revenues, net income or
assets attributable to such ownership interest or investment is equal or greater
than 20% of the annual revenues, net income or assets of the Company. For
purposes of this Agreement, a "Superior Proposal" means any bona fide proposal
to acquire directly or indirectly for consideration consisting of cash and/or
securities all of the Shares then issued and outstanding (by tender offer,
merger or otherwise) or all or substantially all the assets of the Company and
otherwise on terms which the Company Board by a majority vote determines in its
good faith judgment (consistent with the advice of a financial adviser of
nationally recognized reputation) to be more favorable to the Company's
stockholders than the Merger and the Offer. At and after the Tender Offer
Purchase Time, the Company shall not under any circumstances withdraw its
recommendation of the transactions contemplated hereby or approve or recommend,
or cause the Company to enter into any agreement with respect to, any Third
Party Acquisition.

         SECTION 5.5. ACCESS TO INFORMATION. From the date of this Agreement
until the earlier of the termination of this Agreement pursuant to Section 8.1
or the Closing Time, upon reasonable prior notice, the Company shall (and shall
cause each of its subsidiaries to) (a) give the Parent and its representatives
full access, during normal business hours and at other reasonable times without
disruption to the Company's normal business affairs, to the books, records,
contracts, commitments, properties, offices and other facilities of it and its
subsidiaries, (b) arrange for Parent and its representatives reasonable access,
during normal business hours, to the officers, employees and agents of it and
its subsidiaries, and (c) furnish promptly to the Parent and its representatives
such financial and operating data and other information concerning the business,
operations, properties, contracts, records and personnel of the Company and its
subsidiaries as the Parent may from time to time reasonably request. Parent
agrees that it will not, and will cause its representatives not to, use any
information or access obtained pursuant to this Section 5.5 for any purpose not
reasonably related to the consummation of the transactions contemplated by this
Agreement. All information obtained by the Parent pursuant to this Section 5.5
shall be kept confidential in accordance with the confidentiality provisions of
the Letter Agreement between Parent and the Company dated as of May 5, 2000 (the
"Confidentiality Agreement").

         SECTION 5.6. PARENT'S LOAN COMMITMENT. From and after the date of this
Agreement, Parent shall use commercially reasonable efforts to comply with the
conditions set forth in the Loan Commitment. No later than the Tender Offer
Purchase Time, Parent shall draw down such term loan in an amount at least equal
to the sum of: (i) the Per Share Amount multiplied by the total number of Shares
outstanding as of that date (assuming full conversion of all shares of the
Convertible Preferred Stock); and (ii) the amount necessary to pay the Per Share
Amount on each Share for which the Warrants are then exercisable. No later than
the Effective Time, Parent shall draw down such term loan in an amount at least
equal to the amount necessary to settle all Company Stock Options in the manner
described in this Agreement. Immediately following such draw, Parent shall
provide the proceeds thereof to Acquisition to enable Acquisition to make the
payments described in the preceding sentence.

         SECTION 5.7. FURTHER ACTIONS.

         (a) Each of the parties hereto shall use commercially reasonable
efforts to take, or cause to be taken, all actions, and to do, or cause to be
done, all things necessary, proper or advisable under applicable laws and
regulations, and consult and fully cooperate with and provide reasonable
assistance to each other party hereto and their respective representatives in
order to consummate and make effective the transactions contemplated by this
Agreement as promptly as practicable hereafter, including, without limitation,
(i) using commercially reasonable efforts to make all filings, applications,
notifications, reports, submissions and registrations with, and to obtain all
consents, approvals, authorizations or permits of, Governmental Entities
(including, without limitation, the FDA and the DEA) or other Persons as are
necessary for commencement and consummation of the Offer and for the
consummation of the Merger and the other transactions contemplated hereby
(including, without limitation, pursuant to the HSR Act, the Securities Act, the
Exchange Act, Blue Sky Laws, Maryland law and other applicable laws and
regulations in effect in the United States or any other jurisdiction), (ii)
using commercially reasonable efforts to obtain the consents of the Maryland
Industrial Development Financing Authority, First Union National Bank and the
Mayor and City Council of Baltimore with respect to the outstanding bonds, loans
and letters or lines of credit extended to the Company by such parties and (iii)
taking such actions and doing such things as any other party hereto may
reasonably request in order to cause any of the conditions to such other party's
obligation to consummate the Merger as specified in Article 7 of this Agreement
to be fully satisfied. Prior to making any application to or filing with any
Governmental Entity or other Person in connection with this Agreement, the
Company, on the one hand, and the Parent and Acquisition, on the other hand,
shall provide the other with drafts thereof and afford the other a reasonable
opportunity to comment on such drafts.

         (b) Without limiting the generality of the foregoing, each of the
Parent and the Company agrees to cooperate and use reasonable efforts to
vigorously contest and resist any action, suit, proceeding or claim, and to have
vacated, lifted, reversed or overturned any injunction, order, judgment or
decree (whether temporary, preliminary or permanent), that delays, prevents or
otherwise restricts the consummation of the Offer, the Merger or any other
transaction contemplated by this Agreement, and to take any and all actions (but
not including the disposition of material assets, divestiture of businesses, or
the withdrawal from doing business in particular jurisdictions, if material) as
may be required by Governmental Entities as a condition to the granting of any
such necessary approvals or as may be required to avoid, vacate, lift, reverse
or overturn any injunction, order, judgment, decree or regulatory action
(provided, however, that in no event shall any party hereto take, or be required
to take, any action that could reasonably be expected to have a Material Adverse
Effect or that, individually or in the aggregate, could reasonably be expected
to have a Parent Material Adverse Effect).

         SECTION 5.8. PUBLIC ANNOUNCEMENTS. Parent and Acquisition on the one
hand, and the Company, on the other hand, will consult with one another and
mutually agree upon the content and timing of any press releases or public
statements with respect to the transactions

                                      -38-
<PAGE>

contemplated by this Agreement, including, without limitation, the Offer and the
Merger, and shall not issue any such press release or make any such public
statement prior to such consultation and agreement except to the extent that
such disclosure may be required by applicable law or by obligations pursuant to
any listing agreement with the Toronto Stock Exchange or the Nasdaq National
Market as reasonably determined by Parent, Acquisition or the Company, as the
case may be.

         SECTION 5.9. EMPLOYEE BENEFIT MATTERS.

         (a) Parent agrees that, effective as of the Effective Time and for a
one year period following the Effective Time, Parent shall provide, or cause
Acquisition and its subsidiaries and successors to provide, those persons who,
immediately prior to the Effective Time, were employees of the Company and its
subsidiaries and who continue in such employment ("Continuing Employees"), with
benefits and compensation no less favorable in the aggregate to benefits and
compensation that are provided to the Continuing Employees as of the date of
this Agreement.

         (b) Except with respect to accruals under any defined benefit pension
plan, at such time as a Continuing Employee is provided benefits under the
benefit plans or arrangements of Parent or the Surviving Corporation, or any
subsidiary of Parent or the Surviving Corporation, Parent will, or will cause
the Surviving Corporation and its subsidiaries to, give such Continuing Employee
full credit for purposes of eligibility and vesting under such employee benefit
plans or arrangements maintained by Parent, Acquisition or any subsidiary of
Parent or Acquisition for such Continuing Employees' service with the Company or
any subsidiary of the Company to the same extent recognized by the Company at
such time. Parent will, or will cause the Surviving Corporation and its
subsidiaries to, (i) waive all limitations as to preexisting conditions (except
to the extent that such limitations were not waived under the Company's
then-existing welfare plans), exclusions and waiting periods with respect to
participation and coverage requirements applicable to the Continuing Employees
under any welfare plan that such employees may be eligible to participate in
after the Effective Time, and (ii) provide each Continuing Employee with credit
for any co-payments and deductibles paid prior to the Effective Time in
satisfying any applicable deductible or out-of-pocket requirements under any
welfare plans that such employees are eligible to participate in after the
Effective Time to the same extent as if those deductibles or co-payments had
been paid under the welfare plans for which such employees are eligible after
the Effective Time.

         (c) Parent and Acquisition agree (i) to cause Acquisition after
consummation of the Merger contemplated by this Agreement to assume, honor, and
pay all amounts provided under, all Company Employee Plans in accordance with
their terms, and (ii) to honor and to cause Acquisition to honor, all rights,
privileges and modifications to or with respect to any such Company Employee
Plans that become effective as a result of any of the transactions contemplated
by this Agreement.

         SECTION 5.10. EXPENSES. Whether or not the Merger is consummated,
subject to Section 8.3 hereof, all costs and expenses incurred in connection
with this Agreement and the transactions contemplated hereby (including, without
limitation, fees and disbursements of representatives) shall be borne by the
party which incurs such cost or expense. Parent and Acquisition acknowledge that
certain of such costs and expenses may be payable by the Company or the
Surviving Corporation after consummation of the Offer or the Merger.
Accordingly, Parent and Acquisition agree that they will take all commercially
reasonable action to enable the Company or the Surviving Corporation to pay such
costs and expenses as promptly as is practicable after consummation of the Offer
and the Merger and will not contest or challenge the amount thereof; provided
that such costs and expenses are either (i) in the case of the Company's
agreement with its financial advisor, Arnhold and S. Bleichroeder, Inc., not
more than the amount described in the agreement dated March 22, 2000, (ii) in
the case of the performance bonuses to Messrs. Thomas P. Rice and John T. Botek,
not more than the amounts described in Section 2.2 (c) of the Management
Employment Agreements; or (iii) in the case of the Company's legal counsel,
independent auditors or others, not more than is commercially reasonable.

         SECTION 5.11. NOTIFICATION OF CERTAIN MATTERS. The Company shall give
prompt notice to Parent and Acquisition, and Parent and Acquisition shall give
prompt notice to the Company, as the case may be, of (a) the occurrence or
nonoccurrence of any event the occurrence or nonoccurrence of which would be
likely to cause any covenant, condition or agreement contained in this Agreement
not to be complied with or satisfied in all material respects prior to the
Tender Offer Purchase Time, (b) any material failure of the Company, Parent or
Acquisition, as the case may be, to comply with or satisfy any covenant,
condition or agreement to be complied with or satisfied by it hereunder, (c) the
Company's becoming aware of any facts that have caused, or reasonably could be
expected to cause, a violation by the Company of any Regulatory Law or
regulations of the FDA or the DEA, (d) the Company's receipt of any notice,
request for information or other writing from the FDA or the DEA (other than
routine notices sent by the FDA or the DEA generally to regulated companies and
which require no action or response thereto by the Company); and (e) the
Company's becoming aware of any facts that have caused, or could reasonably be
expected to cause, a breach, termination or non-renewal of any contract under
which the Company manufactures, packages, labels or tests a Product or that
otherwise constitutes a materially adverse development with respect to the
Company's business relationship with its customer under any such contract;
provided, however, that the delivery of any notice pursuant to this Section 5.11
shall not cure such breach or non-compliance or limit or otherwise affect the
remedies available hereunder to the party receiving such notice.

         SECTION 5.12. GUARANTEE OF PERFORMANCE. Parent hereby guarantees the
timely and full performance by Acquisition and, after the Effective Time, the
Surviving Corporation of each of its obligations under this Agreement, including
but not limited to the Surviving Corporation's obligations under Section 5.13.

<PAGE>

         SECTION 5.13. INDEMNIFICATION; DIRECTORS' AND OFFICERS' INSURANCE.
Subject to the occurrence of the Effective Time, the Surviving Corporation shall
cause its Articles of Incorporation and Bylaws to contain the indemnification
provisions set forth in the Articles of Incorporation and Bylaws of the Company
on the date of this Agreement, which provisions thereafter shall not be amended,
repealed or otherwise modified after the Effective Time in any manner that could
reasonably be expected to adversely affect the rights thereunder of individuals
who at any time prior to the Effective Time were directors, officers or
employees of the Company in respect of actions or omissions occurring at or
prior to the Effective Time (including, without limitation, the transactions
contemplated by this Agreement). Parent shall cause the Surviving Corporation to
comply with the terms of and maintain in existence any current indemnification
agreements between the Company and any of its directors or officers. In the
event the Surviving Corporation or any of its successors or assigns (a)
consolidates with or merges into any other Person and the Surviving Corporation
shall not be the continuing or surviving corporation or entity of such
consolidation or merger or (b) transfers all or substantially all of its
properties and assets to any Person, then, and in each such case, proper
provision shall be made so that the successors and assigns of the Surviving
Corporation shall assume the obligations set forth in this Section 5.13. The
Surviving Corporation shall obtain and maintain in effect for not less than five
years after the Effective Time, the current policies of directors' and officers'
liability insurance and fiduciary liability insurance maintained by the Company
and the Company's subsidiaries with respect to matters occurring at or prior to
the Effective Time (including, without limitation, the transactions contemplated
by this Agreement), provided, that Parent may, with no lapse in coverage,
substitute therefore policies of substantially the same coverage containing
terms and conditions which are no less advantageous, in any material respect, to
the Company's present or former directors, officers, employees, agents or other
individuals otherwise covered by such insurance policies prior to the Effective
Time (the "Indemnified Parties"). This Section 5.13 is intended to benefit the
Indemnified Parties and shall be binding on all successors and assigns of
Parent, Acquisition, the Company and the Surviving Corporation.

                             CONDITIONS TO THE OFFER

         SECTION 6.1. CONDITIONS TO THE OFFER.

         (a) Notwithstanding any other provisions of the Offer, Acquisition
shall not be required to accept for payment or, subject to any applicable rules
and regulations of the SEC including Rule 14e-l(c) under the Exchange Act
(relating to Acquisition's obligation to pay for or return tendered Shares
promptly after termination or withdrawal of the Offer), pay for, and may delay
the acceptance for payment of or, subject to the restrictions referred to above,
the payment for, any tendered Shares, if (w) any waiting periods applicable to
the Offer under the HSR Act shall not have been terminated or shall not have
expired; (x) any of the consents or approvals of any Person other than a
Governmental Entity, in connection with the execution, delivery and

                                      -41-
<PAGE>

performance of this Agreement shall not have been obtained; except where the
failure to have obtained any such consent or approval would not have a Material
Adverse Effect; (y) the Minimum Condition shall not have been satisfied or (z)
at any time on or after the date of this Agreement and before the time of
acceptance of such Shares for payment pursuant to the Offer, any of the
following events shall occur:

              (i) the Company shall not have received the consents required by
the agreements between the Company and the Maryland Industrial Development
Financing Authority, First Union National Bank and the Mayor and City Council of
Baltimore;

              (ii) from the date of this Agreement until the Tender Offer
Purchase Time, any Governmental Entity or court of competent jurisdiction shall
have enacted, issued, promulgated, enforced or entered any statute, rule,
regulation, executive order, decree, injunction or other order which is in
effect at the Tender Offer Purchase Time and which (A) makes the acceptance for
payment of, or the payment for, any or all of the Shares illegal or otherwise
prohibits consummation of the Offer, the Merger or any of the other transactions
contemplated hereby, or (B) prohibits Acquisition from operating the business of
the Company in substantially the same manner as it is currently conducted;
provided, however, that the parties shall use commercially reasonable efforts
(subject to the proviso in Section 5.6(b)) to cause any such decree, judgment or
other order to be vacated or lifted prior to the Tender Offer Purchase Time;

              (iii) the representations and warranties of the Company set forth
in this Agreement shall not be true and correct on the date of this Agreement or
the expiration time of the Offer, as it may be extended from time to time, or
the Company shall have breached or failed in any respect to perform or comply
with any material obligation, agreement or covenant required by this Agreement
to be performed or complied with by it at or prior to such time except where the
failure of representations and warranties (without regard to materiality
qualifications therein contained) to be true and correct, or the performance or
compliance with such obligations, agreements or covenants, would not,
individually or in the aggregate, have a Material Adverse Effect;

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

              (v) there shall have occurred an acceptance by the Company of a
Superior Proposal;

              (vi) the Board shall have withdrawn or modified in a manner
adverse to Parent its approval or recommendation of the Offer, shall have

have adopted any resolution to effect any of the foregoing;

              (vii) from the date of this Agreement until the Tender Offer
Purchase Time, there shall have occurred the commencement of a war having a
Material Adverse Effect on the

                                      -42-
<PAGE>

Company; which, in the reasonable judgment of Parent and Acquisition, in any
such case, and regardless of the circumstances giving rise to any such
condition, makes it inadvisable to proceed with the Offer and/or with such
acceptance for payment or payments.

              (viii) the Loan Commitment shall have been withdrawn by the Bank.

              (ix) Parent shall not have received the favorable opinion of Piper
Marbury Rudnick & Wolfe LLP with respect to certain tax matters related to
compensation payable to the Company's executive officers.

         (b) The conditions set forth in Section 6.1(a) (other than the Minimum
Condition) are for the sole benefit of Acquisition and may be asserted by
Acquisition regardless of any circumstances giving rise to any condition and may
be waived (other than the Minimum Condition) by Acquisition, in whole or in
part, at any time and from time to time, in the sole discretion of Acquisition.
The failure by Parent or Acquisition (or any affiliate of Acquisition) at any
time to exercise any of the foregoing rights will not be deemed a waiver of any
right and each right will be deemed an ongoing right which may be asserted at
any time and from time to time.

         (b) no Governmental Entity or court of competent jurisdiction shall
have enacted, issued, promulgated, enforced or entered any statute, rule,

                         TERMINATION; AMENDMENT; WAIVER

         SECTION 8.1. TERMINATION. This Agreement may be terminated and the
Merger may be abandoned at any time prior to the Closing Time whether before or
after approval and adoption of this Agreement by the Company's stockholders:

         (a) by mutual written consent of Parent, Acquisition and the Company;

         (b) by Parent or the Company if (i) any Governmental Entity or court of
competent jurisdiction shall have enacted, issued, promulgated, enforced or
entered any statute, rule, regulation, executive order, decree, injunction or
other order which is in effect and which makes payment of the Per Share Amount
or the Cash Merger Consideration illegal or otherwise prohibits the Offer or the
Merger or (ii) Acquisition shall not have purchased that number of Shares
necessary to satisfy the Minimum Condition pursuant to the Offer within the time
periods described in Section 1.1(b) or the Merger shall not have occurred on or
prior to February 28, 2001, provided, that the right to terminate this Agreement
pursuant to this Section 8.1(b) shall not be available to any party who fails to
fulfill any of its obligations under this Agreement and such failure results in
Acquisition's failure to purchase such number of Shares.

         (c) by Parent and Acquisition prior to the Tender Offer Purchase Time
if there shall have been a breach of any covenant or agreement on the part of
the Company resulting in a Material Adverse Effect or a Parent Material Adverse
Effect which shall not have been cured prior to the earlier of (A) 10 days
following notice of such breach and (B) two business days prior to the date on
which the Offer expires as such date may be extended;

         (d) by the Company prior to the Tender Offer Purchase Time if (i) the
Company shall have received a Superior Proposal, shall have furnished Parent a
reasonable written notice advising Parent that the Board has received a Superior
Proposal, specifying the material terms and conditions of such Superior Proposal
and identifying the Person making such Superior Proposal and Parent shall not,
within three business days of Parent's receipt of the Notice of Superior
Proposal, have made an offer which the Company Board, by a majority vote,
determines in its good faith judgment (consistent with the advice of a financial
advisor of nationally recognized reputation) to be at least as favorable to the
Company's stockholders as such Superior Proposal, provided, however, that such
termination under this clause (i) shall not be effective until payment of the
fee required by Section 8.3(b) if such payment is still payable after giving
effect to Section 8.3(c); (ii) there shall have been a breach of any
representation or warranty on the part of Parent or Acquisition which materially
adversely affects (or materially delays) the consummation of the Offer or
results in a Parent Material Adverse Effect or (iii) there shall have been a
material breach of any covenant or agreement on the part of Parent or
Acquisition and which materially adversely affects (or materially delays) the
consummation of the Offer which

                                      -44-
<PAGE>

shall not have been cured prior to the earlier of (A) 10 days following notice
of such breach and (B) two business days prior to the date on which the Offer
expires as such date may be extended.

         SECTION 8.2. EFFECT OF TERMINATION. In the event of the termination of
this Agreement and abandonment of this Agreement pursuant to Section 8.1, this
Agreement shall forthwith become void and have no effect without any liability
on the part of any party hereto or its affiliates, directors, officers or
stockholders other than the provisions of this Section 8.2 and the last sentence
of Sections 5.5, and Sections 8.3 and 9.1 through 9.12 hereof. Nothing contained
in this Section 8.2, however, shall relieve any party from liability for any
willful breach of this Agreement.

         SECTION 8.3. FEES AND EXPENSES.

Section 8.3(c), the Company shall pay to Acquisition the amount of $2,150,000
(the "Breakup Fee") immediately upon such a termination.

         (b) Subject to the provisions of Section 8.3(c), the Breakup Fee shall
be payable

              (i) if the Offer is terminated pursuant to Section 6.1(a) (vi) and
within one year after such termination either (x) the Company enters into an
agreement to merge with another company (other than a merger pursuant to which
the stockholders of the Company will acquire more than fifty percent (50%) of
the voting securities of such surviving corporation) or enters into an agreement
pursuant to which more than 50% of the issued and outstanding Shares are
acquired by another person or pursuant to which new voting securities are issued
to another person or to the stockholders of another company which will aggregate
more than fifty percent (50%) of the outstanding voting securities of the
Company after such issuance or (y) another person acquires more than fifty
percent (50%) of the issued and outstanding Shares, in which case the Company
shall promptly, but in no event later than two days after the date of any of the
events in (x) or (y), pay Parent the Breakup Fee; or

              (ii) the Company shall have terminated this Agreement pursuant to
Section 8.1(d)(i).

         (c) Notwithstanding the provisions of subsections (a) and (b) above,
Acquisition may, at its sole option, at any time prior to the expiration of
three business days after Parent's receipt of notice of the Superior Proposal in
accordance with Section 8.1(d), waive payment of the Breakup Fee in order to
exercise its options, in whole or in part, to purchase certain Shares pursuant
to Section 3 of the Stockholders' Agreement (the "Options"). In the event of any
such exercise, in whole or in part, the Breakup Fee shall no longer be payable.

         SECTION 8.4. AMENDMENT. This Agreement may be amended by action taken
by the Board subject to Section 1.3(c), and by the parties hereto at any time
before or after approval, if necessary, of the Merger by the stockholders of the
Company but, after any such approval, no amendment shall be made which requires
the approval of such stockholders under applicable law without such approval.
This Agreement may not be amended except by an instrument in writing signed on
behalf of the parties hereto.

         SECTION 8.5. EXTENSION; WAIVER. At any time prior to the Closing Time,
each party hereto may in its sole discretion (i) extend the time for the
performance of any of the obligations or other acts of the other party, (ii)
waive any inaccuracies in the representations and warranties of the other party
contained herein or in any document, certificate or writing delivered pursuant
hereto or (iii) waive compliance by the other party with any of the agreements
or conditions contained herein. Any agreement on the part of any party hereto to
any such extension or waiver

                                      -46-
<PAGE>

shall be valid only if set forth in an instrument, in writing, signed on behalf
of such party. The failure of any party hereto to assert any of its rights
hereunder shall not constitute a waiver of such rights.

                                  MISCELLANEOUS

         SECTION 9.1. ENTIRE AGREEMENT; ASSIGNMENT. This Agreement, the
Confidentiality Agreement, the Option and the Stockholders' Agreement together
(a) constitute the entire agreement among the parties hereto with respect to the
subject matter hereof and supersede all other prior agreements and
understandings both written and oral among the parties or any of them with
respect to the subject matter hereof and (b) shall not be assigned by operation
of law or otherwise.

         SECTION 9.2. SURVIVAL OF REPRESENTATIONS AND WARRANTIES. The
representations and warranties made herein shall not survive beyond the earlier
of (i) termination of this Agreement or (ii) the Tender Offer Purchase Time, in
the case of the representations and warranties of Parent or Acquisition or the
purchase of Shares by Acquisition pursuant to the Offer, in the case of the
representations and warranties of the Company. This Section 9.2 shall not limit
any covenant or agreement of the parties hereto which by its terms contemplates
performance after the Tender Offer Purchase Time.

         SECTION 9.3. VALIDITY. If any provision of this Agreement or the
application thereof to any Person or circumstance is held invalid or
unenforceable the remainder of this Agreement and the application of such
provision to other Persons or circumstances shall not be affected thereby and to
