              PLEASE READ THE ACCOMPANYING INSTRUCTIONS CAREFULLY

Ladies and Gentlemen:

     The undersigned hereby tenders to AC Acquisition Subsidiary, Inc., a
Maryland corporation (the "Purchaser"), which is a wholly owned subsidiary of
Cangene Corporation, the above described shares of series A-1 convertible
preferred stock, par value $.01 per share (the "Shares") of Chesapeake
Biological Laboratories, Inc., a Maryland corporation (the "Company"), at a
price of $4.60 per Share multiplied by the number of shares of common stock,
par value $.01 per share, of the Company into which such Shares are then
convertible, net to the seller in cash, less any required withholding of taxes
and without the payment of interest, upon the terms and subject to the
conditions set forth in the Offer to Purchase, dated November 17, 2000 (the
"Offer to Purchase"), receipt of which is hereby acknowledged, and in this
Letter of Transmittal (which, together with any amendments or supplements
thereto, constitute the "Offer").

     Subject to, and effective upon, acceptance for payment of 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, Purchaser all
right, title and interest in and to all of the Shares that are being tendered
hereby and any and all dividends, distributions, rights, other Shares or other
securities issued, paid or distributed or issuable, payable or distributable in
respect of such Shares on or after November 17, 2000 and prior to the transfer
to the name of Purchaser (or a nominee or transferee of Purchaser) on the
Company's stock transfer records of the Shares tendered herewith (collectively,
a "Distribution"), and irrevocably appoints the Depositary the true and lawful
agent, attorney-in-fact and proxy of the undersigned with respect to such
Shares (and any Distribution), with full power of substitution (such power of
attorney being deemed to be an irrevocable power coupled with an interest) to
(a) deliver certificates representing such Shares ("Share Certificates")(and
any Distribution), together with appropriate evidences of transfer, to the
Depositary for the account of Purchaser, (b) present such Shares (and any
Distribution) 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 Distribution), all in accordance with the terms and subject to
the conditions of the Offer.

     The undersigned irrevocably appoints designees of Purchaser as such
undersigned's agents, attorneys-in-fact and proxies, with full power of
substitution, to the full extent of such stockholder's rights with respect to
the Shares (and any Distribution) tendered by such stockholder and accepted for
payment by Purchaser. All such powers of attorney and proxies shall be
considered irrevocable and coupled with an interest. Such appointment will be
effective when, and only to the extent that, Purchaser accepts such Shares for
payment. Upon such acceptance for payment, all prior powers of attorney,
proxies and consents given by such stockholder with respect to such Shares (and
any Distribution) will be revoked without further action, and no subsequent
powers of attorney and


                                       2


proxies may be given nor any subsequent written consents executed (and, if
given or executed, will not be deemed effective). The designees of Purchaser
will, with respect to the Shares (and Distributions) for which such appointment
is effective, be empowered to exercise all voting and other rights of such
stockholder as they in their sole discretion may deem proper at any annual or
special meeting of Company stockholders or any adjournment or postponement
thereof, by written consent in lieu of any such meeting or otherwise. Purchaser
reserves the right to require that, in order for the Shares to be deemed
validly tendered, immediately upon Purchaser's acceptance of such Shares,
Purchaser must be able to exercise full voting rights with respect to such
Shares and all Distributions, including, without limitation, voting at any
meeting of stockholders.


     The undersigned hereby represents and warrants that (a) the undersigned
has full power and authority to tender, sell, assign and transfer the
undersigned's Shares (and any Distribution) tendered hereby, and (b) when the
Shares are accepted for payment by Purchaser, Purchaser will acquire good,
marketable and unencumbered title to the Shares (and any Distribution), free
and clear of all liens, restrictions, charges and encumbrances, and the same
will not be subject to any adverse claim and will not have been transferred to
Purchaser in violation of any contractual or other restriction on the transfer
thereof. The undersigned, upon request, will execute and deliver any additional
documents deemed by the Depositary or Purchaser to be necessary or desirable to
complete the sale, assignment and transfer of the Shares tendered hereby (and
any Distribution). In addition, the undersigned shall promptly remit and
transfer to the Depositary for the account of Purchaser any and all
Distributions in respect of the Shares tendered hereby, accompanied by
appropriate documentation of transfer, and, pending such remittance or
appropriate assurance thereof, Purchaser will be, subject to applicable law,
entitled to all rights and privileges as owner of any such Distribution and may
withhold the entire purchase price or deduct from the purchase price the amount
or value thereof, as determined by Purchaser, in its sole discretion.


     All authority herein conferred or agreed to be conferred shall not be
affected by and shall survive the death or incapacity of the undersigned and
any obligation of the undersigned hereunder shall be binding upon the heirs,
personal representatives, successors and assigns of the undersigned.


     Tenders of Shares made pursuant to the Offer are irrevocable, except that
Shares tendered pursuant to the Offer may be withdrawn at any time prior to the
Expiration Date, and, unless theretofore accepted for payment by the Purchaser
pursuant to the Offer, may also be withdrawn at any time after January 3, 2001.
See Section 4 of the Offer to Purchase.


     The undersigned understands that tenders of Shares pursuant to any of the
procedures described in Section 3 of the Offer to Purchase and in the
instructions hereto will constitute a binding agreement between the undersigned
and Purchaser upon the terms and subject to the conditions set forth in the
Offer, including the undersigned's representation that the undersigned owns the
Shares being tendered.


     Unless otherwise indicated herein under "Special Payment Instructions,"
please issue the check for the purchase price and/or issue or return any
certificate(s) for Shares not tendered or not accepted for payment in the
name(s) of the registered holder(s) appearing under "Description of Shares
Tendered." Similarly, unless otherwise indicated herein under "Special Delivery
Instructions," please mail the check for the purchase price and/or any Share
Certificate(s) not tendered or not accepted for payment (and accompanying
documents, as appropriate) to the address(es) of the registered holder(s)
appearing under "Description of Shares Tendered." In the event that both the
"Special Delivery Instructions" and the "Special Payment Instructions" are
completed, please issue the check for the purchase price and/or any Share
Certificate(s) not tendered or accepted for payment in the name of, and deliver
such check and/or such Share Certificate(s) to, the person or persons so
indicated. The undersigned recognizes that the Purchaser has no obligation,
pursuant to the Special Payment Instructions, to transfer any Shares from the
name(s) of the registered holder(s) thereof if the Purchaser does not accept
for payment any of the Shares so tendered.

                                 INSTRUCTIONS
             FORMING PART OF THE TERMS AND CONDITIONS OF THE OFFER

     1. Guarantee of Signatures. No signature guarantee is required on this
Letter of Transmittal (a) if this Letter of Transmittal is signed by the
registered holder(s) of Shares tendered herewith, unless such holder(s) has
completed either the box entitled "Special Payment Instructions" or the box
entitled "Special Delivery Instructions," or (b) if such Shares are tendered
for the account of a firm which is a bank, broker, dealer, credit union,
savings association or other entity which is a member in good standing of a
recognized Medallion Program approved by the Securities Transfer Association
Inc., including the Securities Transfer Agents Medallion Program (STAMP), the
Stock Exchange Medallion Program (SEMP) and the New York Stock Exchange
Medallion Signature Program (MSP) or any other "eligible guarantor institution"
(as defined in Rule 17Ad-15 under the Securities Exchange Act of 1934) (each of
the foregoing, an "Eligible Institution"). In all other cases, all signatures
on this Letter of Transmittal must be guaranteed by an Eligible Institution.
See Instruction 5 of this Letter of Transmittal.

     2. Requirements of Tender. This Letter of Transmittal is to be completed
by stockholders either if Share Certificates are to be forwarded herewith.
Share Certificates evidencing tendered Shares, as well as this Letter of
Transmittal (or a facsimile hereof), properly completed and duly executed, with
any required signature guarantees, and any other documents required by this
Letter of Transmittal, must be received by the Depositary at one of its
addresses set forth herein on or prior to the Expiration Date. If Share
Certificates are forwarded separately in multiple deliveries to the Depositary,
a properly completed and duly executed Letter of Transmittal (or a facsimile
thereof) must accompany each such delivery.

     THE METHOD OF DELIVERY OF THIS LETTER OF TRANSMITTAL, SHARE CERTIFICATES
AND ALL OTHER REQUIRED DOCUMENTS IS AT THE OPTION AND RISK OF THE TENDERING
STOCKHOLDER, AND THE DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED
BY THE DEPOSITARY. 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 STOCKHOLDERS, BY EXECUTION OF THIS LETTER OF TRANSMITTAL (OR A
FACSIMILE HEREOF), 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 Share
Certificate numbers and/or the number of Shares and any other required
information should be listed on a separate signed schedule attached hereto.

     4. Partial Tenders. If fewer than all the Shares evidenced by any Share
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 the
"Description of Shares Tendered." In such cases, new Share Certificates for the
Shares that were evidenced by your old Share Certificates, but were not
tendered by you, will be sent to you, unless otherwise provided in the
appropriate box on this Letter of Transmittal, as soon as practicable after the
Expiration Date. All Shares represented by Share 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 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 of
the tendered Shares are registered in different names on several 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 a fiduciary or
representative capacity, such persons should so indicate when signing, and
proper evidence satisfactory to the Purchaser of their authority so to act must
be submitted.


                                       6


     If this Letter of Transmittal is signed by the registered holder(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 not purchased are to be issued in the
name of, a person other than the registered holder(s). In such latter case,
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 holder(s) of the Share Certificate(s) listed, the Share
Certificate(s) must be endorsed or accompanied by appropriate stock powers, in
either case signed exactly as the name(s) of the registered holder(s) appear on
the Share Certificate(s). Signatures on such certificates or stock powers must
be guaranteed by an Eligible Institution.

     6. Stock Transfer Taxes. Except as otherwise provided in this Instruction
6, Purchaser will pay any stock transfer taxes with respect to the transfer and
sale of Shares to it or its order pursuant to the Offer. If, however, payment
of the purchase price is to be made to, or if Share Certificates for Shares not
tendered or accepted for payment are to be registered in the name of, any
person other than the registered holder(s), 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(s) 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 an exemption therefrom, is submitted.
Except as otherwise provided in this Instruction 6, it will not be necessary
for transfer tax stamps to be affixed to the Share Certificate(s) 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 Shares not tendered or not
accepted for payment are to be issued or returned to, a person other than the
signer of this Letter of Transmittal or if a check and/or such Share
Certificates are to be returned to a person other than the person(s) signing
this Letter of Transmittal or to an address other than that shown in this
Letter of Transmittal, the appropriate boxes on this Letter of Transmittal must
be completed.

     8. Waiver of Conditions. Subject to the terms and conditions of the Merger
Agreement (as defined in the Offer to Purchase), the conditions of the Offer
may be waived by the Purchaser in whole or in part at any time and from time to
time in its sole discretion.

     9. 31% Backup Withholding; Substitute Form W-9. Under U.S. federal income
tax law, a stockholder who tenders Shares pursuant to the Offer is required to
provide the Depositary with such stockholder's correct taxpayer identification
number ("TIN") on Substitute Form W-9 and to certify that the TIN provided on
Substitute Form W-9 is correct (or that such stockholder is awaiting a TIN). If
such stockholder is an individual, the TIN is his or her social security
number. If the Depositary is not provided with the correct TIN, such
stockholder may be subject to a $50 penalty imposed by the Internal Revenue
Service and payments that are made to such stockholder with respect to Shares
pursuant to the Offer may be subject to backup withholding (see below).

     A stockholder who does not have a TIN may check the box in Part 3 of the
Substitute Form W-9 if such stockholder has applied for a number or intends to
apply for a TIN in the near future. If the box in Part 3 is checked, the
stockholder must also complete the "Certificate of Awaiting Taxpayer
Identification Number" below in order to avoid backup withholding. If the box
is checked, payments made will be subject to backup withholding unless the
stockholder has furnished the Depositary with his or her TIN within 60 days. A
stockholder who checks the box in Part 3 in lieu of furnishing such
stockholder's TIN should furnish the Depositary with such stockholder's TIN as
soon as it is received.

     Certain stockholders (including, among others, all corporations and
certain foreign individuals) are not subject to these backup withholding
requirements. In order for a foreign individual to qualify as an exempt
recipient, that stockholder must submit a statement, signed under penalty of
perjury, attesting to that individual's exempt status (Form W-8). Forms for
such statements can be obtained from the Depositary. Stockholders are urged to
consult their own tax advisors to determine whether they are exempt from these
backup withholding and reporting requirements.

     If backup withholding applies, the Depositary is required to withhold 31%
of any payments to be made to the stockholder. 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 by filing a tax
return with the Internal Revenue Service. The Depositary cannot refund amounts
withheld by reason of backup withholding.


     10. Requests for Assistance or Additional Copies. Questions or requests
for assistance may be directed to the Information Agent at the address and
telephone number set forth below. Additional copies of the Offer to Purchase
and this Letter of Transmittal also may be obtained from the Information Agent
or from brokers, dealers, commercial banks or trust companies.


     11. Lost, Destroyed or Stolen Certificates. If any Share Certificate has
been lost, destroyed or stolen, the stockholder should promptly notify the
Depositary. The stockholder then will be instructed as to the steps that must
be taken in order to replace the Share Certificate. 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 HEREOF), TOGETHER WITH
SHARE CERTIFICATES, AND ALL OTHER REQUIRED DOCUMENTS, MUST BE RECEIVED BY THE
DEPOSITARY ON OR PRIOR TO THE EXPIRATION DATE.
