                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.  Organization:
    -------------

    Chesapeake Biological Laboratories, Inc. ("CBL" or "the Company") is an 
    established provider of pharmaceutical and biopharmaceutical product 
    development and production services on a contract basis for a broad range 
    of customers, from major international pharmaceutical firms to emerging 
    biotechnology companies. Since 1990, CBL has provided its product 
    development services to more than 90 pharmaceutical and biotechnology 
    companies and has contributed to the development and production of more 
    than 100 therapeutic products intended for human clinical trials. 
    Customers contract with the Company to produce development stage products 
    for use in Food and Drug Administration ("FDA") clinical trials and to 
    produce and manufacture FDA approved products for commercial sale. The 
    Company's business depends, in part, on strict government regulation of 
    the drug development process, especially in the United States. CBL's 
    production facility operates under the current Good Manufacturing 
    Practices ("cGMP") established and regulated by the FDA.

2.  Summary of Significant Accounting Policies:
    -------------------------------------------

    Principles of Consolidation
    ---------------------------

    The accompanying consolidated financial statements include the accounts of 
    CBL and its wholly-owned subsidiary, CBL Development Corp.

    Accounts Receivable
    -------------------

    Accounts receivable are stated net of allowances for doubtful accounts of
    $62,457 and $70,300 as of June 30, 1998 and March 31, 1998, respectively.

    Inventories
    -----------

    Inventories consist of raw materials, work-in-process and finished goods 
    which are stated at the lower of cost or market, determined under the 
    first-in, first-out (FIFO) method.

    Property and Equipment
    ----------------------

    Property and equipment are stated at cost less accumulated depreciation. 
    Equipment is depreciated using the straight-line method over estimated 
    useful lives of three to ten years. The building is depreciated over an 
    estimated useful life of thirty years. Leasehold improvements are 
    amortized over the term of the lease.

    Cash and Cash Equivalents
    -------------------------

    Cash and cash equivalents include amounts invested in securities with 
    maturities of six months or less which are readily convertible to known 
    amounts of cash. Included in restricted cash are Company funds of 
    $350,000 which are being held by the Bond Trustee as collateral for the 
    Company's obligations under the Letter of Credit and Reimbursement 
    Agreement with First Union National Bank of North Carolina (see Note 6).

    Revenue Recognition
    -------------------

    The Company recognizes income when product is shipped or the service has 
    been provided to the customer. Deferred revenues represent deposits 
    normally required of customers with development products.

    Income Taxes
    ------------

    Deferred income taxes are computed using the liability method, which 
    provides that deferred tax assets and liabilities are recorded based on 
    the differences between the tax bases of assets and liabilities and their 
    carrying amounts for financial reporting purposes.

             CHESAPEAKE BIOLOGICAL LABORATORIES, INC AND SUBSIDIARY
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

    Stock Option Plans
      ------------------

    The Company accounts for its stock-option plans in accordance with the 
    provisions of Accounting Principles Board ("APB") Opinion No. 25, 
    "Accounting for Stock Issued to Employees", and related interpretations. 
    As such compensation expense would be recorded on the date of the grant 
    only if the current market price of the underlying stock exceeded the 
    exercise price.

    Use of Estimates
    ----------------

    The preparation of financial statements in conformity with generally 
    accepted accounting principles requires management to make estimates and 
    assumptions that affect the reported amounts of assets and liabilities 
    and disclosure of contingent assets and liabilities as of the date of the 
    financial statements and the reported amounts of revenues and expenses 
    during the reporting period. Actual results could differ from those 
    estimates.

3.  Concentrations of Credit Risk/Significant Customers:
    ----------------------------------------------------

    The Company's customers span the range of the pharmaceutical and medical 
    device industries. For many customers, the Company requires an up-front 
    payment on orders. There are some recurring customers, however, for which 
    CBL has waived that practice.

    The contract manufacturing agreement between the Company and Allergan 
    Botox, Ltd. ("Allergan") for the production of VitraxTM originally 
    expired in February 1997. Subsequent thereto, an agreement was reached 
    between CBL and Allergan which called for the production of VitraxTM 
    through December 31, 1997, on modified terms using active ingredients 
    supplied by Allergan, rather than active ingredients manufactured by CBL. 
    In addition, Allergan was relieved of any obligation to purchase VitraxTM 
    exclusively from the Company. In September 1997, the Company made its 
    final shipment of VitraxTM to Allergan and no further shipments have been 
    made and no further revenues are expected from Allergan relative to 
    VitraxTM.

    The Company has been actively seeking to increase and diversify its 
    customer base and has been successful in its diversification efforts, 11 
    new customers were added during the fiscal year 1998. However, there can 
    be no assurance that the Company's annual results will not be dependent 
    upon the performance of a few large projects.

4.  Inventories:

5.  Leases:
    -------

    In December 1993, the Company entered into a non-cancelable operating lease
    agreement for what was then a second facility in Owings Mills, Maryland to
    house its corporate offices, warehousing, shipping and receiving

                                        8





             CHESAPEAKE BIOLOGICAL LABORATORIES, INC AND SUBSIDIARY
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

    functions. The lease terms had provided for an initial expiration date of 
    December 31, 1998. However, as of June 1, 1997, the Company negotiated 
    termination of the Owings Mills facility lease, effective June 1, 1997, 
    in exchange for a termination fee of $30,200 paid by the Company, 
    resulting in net savings to the Company of approximately $200,000 over 
    the remaining initial term of the lease.

    The Company's Seton Business Park facility is primarily used for 
    experimental development and production and is occupied under a 
    non-cancelable operating lease agreement with an initial six and one-half 
    year term, expiring December 31, 1998 and two renewal terms of two years 
    each. Related rental payments for the three months ended June 30, 1998 
    and 1997, were $59,142 and $59,142, respectively. The operating lease 
    agreement for the Seton Business Park facility contains terms which 
    feature reduced rental payments in the early years and increased payments 
    toward the end of the lease term. For financial reporting purposes, 
    rental expense represents an average of the minimum annual rental 
    payments over the initial six and one-half year term. On an annual basis, 
    this expense is approximately $192,000.

    During previous years, the Company entered into several non-cancelable 
    capital lease obligations for various pieces of laboratory equipment and 
    furniture that expire during fiscal year 1999. In addition, in fiscal 
    year 1997, the Company entered into several operating leases that expire 
    during fiscal year 2001.

    On April 14, 1998, the Company exercised the right to renew the lease of 
    its Seton facility. The lease now expires on December 31, 2000, and may, 
    at the Company's option, be renewed again for another two year period 
    thereafter.

6.  Long Term Debt:
    ---------------

    In November 1996, the Company completed the acquisition of an 
    approximately 70,000 square foot building on 3.48 acres in Baltimore, 
    Maryland, which the Company has renovated to provide CBL with office, 
    warehouse and pharmaceutical manufacturing space. The Company 
    successfully completed the initial FDA general facility inspection on 
    this commercial production facility in July, 1998. The Company is actively 
    seeking opportunities and customer contracts to utilize these FDA 
    approved expanded capabilities. The purchase and renovation costs were 
    financed with a $7,000,000 Economic Development Bond issued by the 
    Maryland Industrial Development Financing Authority, and a $1,500,000 
    loan from the Mayor and City Council of Baltimore City by and through the 
    Department of Housing and Community Development. The loan from the City 
    of Baltimore has an interest rate which is fixed at 6.5%. The bonds are 
    variable rate, tax-exempt and may be converted to a fixed rate.

    The Company has also entered into an interest rate agreement with First 
    Union National Bank of North Carolina to reduce the potential impact of 
    the variable interest rates on the bonds. This agreement results in a 
    maximum interest rate on the bonds of 5.51%, and relates to $6 million of 
    the outstanding bonds. The agreement became effective in November 1996 
    and will expire in November 2003.

    The principal portion of the Bonds, and the accrued interest thereon, is 
    payable from monies drawn under a direct pay Letter of Credit issued by 
    First Union National Bank of North Carolina (the "Bank"), in amounts up 
    to $7,280,000. Interest is payable quarterly, commencing February 1, 
    1997, and principal portions of the bonds are subject to redemption, in 
    part, commencing November 1998, in accordance with a schedule set forth 
    in the bonds. The Maturity Date is August 1, 2018. The loan from the City 
    of Baltimore requires interest only payments for the first two years, and 
    monthly principal and interest payments due thereafter through November 
    2016.

    Under the documentation applicable to the Bond financing, the Company is 
    obligated to maintain certain financial ratios and balances, including a 
    minimum tangible net worth, a liability to net worth ratio, an EBITDA 
    ratio and a current ratio, all as defined and established in the 
    applicable documents. The documentation applicable to the Bond financing 
    includes several additional covenants, including a ceiling on capital 
    expenditures and a limitation on the incurrence of other indebtedness, as 
    defined and established therein. During fiscal year 1998, and subsequent 
    thereto, the Company and the Bank agreed to modify certain of the ratios 
    and balances provided for under the Bond financing documentation, and the 
    Bank agreed to waive through April 1, 1999, the requirement that the 
    Company maintain a certain EBITDA ratio, which was not otherwise met as of

                                        9




             CHESAPEAKE BIOLOGICAL LABORATORIES, INC AND SUBSIDIARY
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

    June 30, 1998. As of June 30, 1998, the Company was in compliance with 
    all of the other ratios and balances required to be maintained under the 
    terms of the Bond financing documentation.

    Other long term debt as of June 30, 1998, consists of loans for a truck 
    and various equipment. The truck loan bears interest at 6.9% and is 
    repayable through December 8, 1998, in equal monthly installments. The 
    equipment loan bears interest at 8.5% and is repayable through April 1, 
    1999 in variable monthly installments.

7.  Earnings per share:
    -------------------

    In March 1997, the Financial Accounting Standards Board (FASB) issued 
    Statement of Financial Accounting Standards (SFAS) No. 128, "Earnings per 
    Share." SFAS 128 simplifies the standards for computing earnings per 
    share ("EPS") previously found in APB Opinion No. 15, "Earnings per 
    Share." It replaces the presentation of primary and fully diluted EPS 
    with a presentation of basic and diluted EPS and requires a 
    reconciliation of the numerator and denominator of the basic and diluted 
    EPS calculation. Basic EPS excludes dilution and is computed by dividing 
    income available to common stockholders by the weighted average number of 
    common shares outstanding for the period. Diluted EPS is computed 
    similarly to primary EPS pursuant to APB Opinion No. 15. The adoption of 
    SFAS 128 did not have a significant impact on the Company for the three 
    months ended June 30, 1998, because of the Company's net loss. Earnings 
    per share information for the prior quarter has been restated to reflect 
    the new requirements.

8.  New accounting pronouncements:
    ------------------------------

    In June 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive 
    Income," and SFAS No. 131, "Disclosures About Segments of an Enterprise 
    and Related Information." The statements will affect the presentation and 
    disclosure requirements for annual and interim financial statements 
    beginning in fiscal year 1999. The Company expects that the new reporting 
    requirements will not have a material impact on its financial statements.

             CHESAPEAKE BIOLOGICAL LABORATORIES, INC. AND SUBSIDIARY

                      Management Discussion and Analysis of
                  Financial Condition and Results of Operations
                  ---------------------------------------------

Results of Operations

The management discussion below should be read in conjunction with the Company's
Annual Report on Form 10-K for the fiscal year ended March 31, 1998.

        Three months ended June 30, 1998 and 1997.

        Operating revenues were $1,117,000 for the three months ended June 30,
1998, as compared to $1,717,000 for the comparable quarter in the prior year.
The decrease was attributed to the elimination of sales to Allergan which
accounted for $618,000 in sales for the same quarter in the prior year.

        Gross profit for the quarter was a loss of $55,000 as compared to a
gross profit of $370,000 for the same quarter last year. This decrease in gross
profit is primarily attributable to the decrease in operating revenues and the
increase in operating costs associated with the Company's recently completed
pharmaceutical production and warehouse space, located at the Camden Industrial
Park, Baltimore, Maryland. Included among the operating costs associated with
the new Camden facility were the costs necessarily incurred to maintain the
pharmaceutical production facility in a state of operational readiness in
connection with validation and FDA inspection, which was successfully completed
on July 8, 1998. Excluding operating costs associated with the new facility
would result, on an adjusted basis, in a positive gross margin of 25% for the
quarter ended June 30, 1998, as compared to an actual gross margin of 27% for
the same quarter in the prior year.

        Quarterly sales and marketing expenses of $247,000 for the quarter were
up $121,000 as compared to the same quarter last year. This increase is
primarily the result of $71,000 in expenses incurred in connection with
reorganization of the Company's Sales and Marketing Department, and an increased
focus on marketing and advertising programs. General and Administrative expenses
were down 3% for the quarter compared to the same quarter last year.

        The $674,000 in operating loss for the three months ended June 30, 1998,
compares to a $166,000 operating loss for the comparable quarter in the prior
year. This loss is the direct result of the decreased revenues and the operating
expenses associated with the Camden facility which generated no revenue as it
was being validated and inspected during the period.

        Other income of $22,000 for the three months ended June 30, 1998,
compares to $47,000 of other income for the comparable quarter in the prior
year. Interest income on the proceeds from the June 1997, follow-on public
equity offering was the primary source of the other income for the three months
ended June 30, 1998.


Financial Condition and Liquidity
- - ---------------------------------

        On June 30, 1998, CBL had cash and cash equivalents of $2,971,000
compared to $3,042,000 at March 31, 1998. These balances do not include $350,000
held as collateral for the Company's obligations under the Letter of Credit and
Reimbursement Agreement with First Union National Bank of North Carolina,
pursuant to which a letter of credit was issued as credit enhancement for bonds
issued by the Maryland Industrial Development Financing Authority. The proceeds
of these bonds were and are being used by the Company to finance a portion of
the purchase price and the renovation and equipping of the Camden production
facility. In addition, and not included in the above sums, $441,000 was held at
June 30, 1998, by the Bond Trustee, under the Trust Indenture entered into in
connection with the bond financing. These funds are held by the Trustee pending
disbursement, subject and pursuant to the terms of the financing documents, to
defray the continuing costs of renovation and equipping of the Camden Industrial
Park facility. The Company continues to maintain a $750,000 Revolving Line of
Credit from the First Union National Bank of Maryland and there was an
outstanding balance of $338,000 at June 30, 1998.

        Net cash used in the operating activities of $19,000 for the three
months ended June 30, 1998, was primarily the result of the net loss for the
period and increase in deferred income taxes which was offset in part by
decreases in accounts receivables and prepaid expenses. This compares to net
cash used in operating activities for the comparable period in the prior year of
$211,000. Net cash used in investing activities of $377,000 for the three
months ended June 30, 1998, was a direct result of the final validation and
completion of the FDA approved Camden production facility offset in part by
disbursements from the bond fund Trustee. This compares to net cash used in
investing activities for the

                                       11





comparable period in the prior year of $53,000. Net cash provided by financing
activities of $325,000 for the three months ended June 30, 1998 was comprised
primarily of short term borrowings from the Company's revolving Line of Credit.
This compares to the net cash provided by financing activities for the
comparable period in the prior year of $3,215,000. Cash provided by financing
activities in the previous year is a direct result of the Company's follow-on
public offering of Class A Common Stock.

Year 2000 Issue
- - ---------------

        In conjunction with the Company' expansion of its commercial production
facility, the Company plans to upgrade both its computer hardware and software.
Management believes the software upgrade will resolve the Year 2000 issue for
the Company. An independent consultant's study of the Company's current
information technology status and recommended changes is nearing completion. The
study is recommending installation of commercially available software packages.
Installation of critical modules is expected to be completed by late 1998. The
software packages under review have been upgraded to handle the Year 2000 by the
software provider. Time-sensitive internal programs have been reviewed and will
require only minor modifications to resolve the Year 2000 issue.

                  The Annual Meeting of Stockholders of the Company was held on
                  July 9, 1998, at 10:00 a.m. at the offices of the Company
                  located at 1111 S. Paca Street, Baltimore, Maryland 21230. At
                  the Annual Meeting of Stockholders, the only action taken by
                  the stockholders was the election of six (6) persons to serve
                  as directors of the Company until the next Annual Meeting of
                  Stockholders and until their successors are duly elected and
                  qualified. These six persons, who constitute the entire Board
                  of Directors of the Corporation, are Narlin B. Beaty, Regis F.
                  Burke, Harvey L. Miller, Thomas P. Rice, William P. Tew and
                  John C. Weiss, III. Thomas C. Mendelsohn, who had served as
                  Director of the Company since 1991, and had been nominated
                  for re-election, resigned from the Board of Directors
                  effective July 7, 1998, and withdrew his name from the ballot
                  and is no longer associated with the Company as a director,
                  officer or employee.

                  Subsequent to The Annual Meeting of Stockholders of the 
                  Company, the Board of Directors elected Robert J. Mello,
                  Ph.D. as Secretary of the Corporation. Dr. Mello, Vice
                  President of Quality and Regulatory Affairs since rejoining
                  the Company in 1994, holds a Ph.D. degree in Biochemistry
                  from the Johns Hopkins University School of Medicine. Dr.
                  Mello had been with the Company for ten years before joining
                  Lederle Laboratories in 1992 as Manager, Validation
                  Services. During his ten years with the Company, Dr. Mello
                  served originally as Director of Research and Development
                  and then as Director, Quality Assurance and Regulatory
                  Affairs, and as Secretary.
