THE PLAN OF LIQUIDATION
- -----------------------

BACKGROUND OF THE
TRANSACTION............    For a description of the events leading
                           to the approval of the Transaction by
                           the Board of Directors of Hallmark, see
                           "SPECIAL FACTORS -- Background and
                           Reasons for the Transaction and the Plan
                           of Liquidation."
   

EFFECT OF THE
TRANSACTION............    Upon consummation of the Transaction,
                           pursuant to the Asset Purchase
                           Agreement, Duramed will acquire
                           substantially all of the assets of
                           Hallmark and will assume certain of
                           Hallmark's liabilities, including its
                           bank indebtedness and certain of its
                           accounts payable, and Hallmark's
                           indebtedness to Duramed ($3,480,520 at
                           July 15, 1996 in the aggregate) will be
                           released.  Duramed will issue to
                           Hallmark for distribution to its
                           creditors and shareholders in accordance
                           with the Plan of Liquidation 640,000
                           shares of Duramed Common Stock and
                           warrants to purchase 400,000 shares of
                           Duramed Common Stock at $25.00 per share
                           (the "Warrants"). Hallmark will retain
                           certain of its liabilities, including
                           indebtedness to certain of its shareholders
                           ($6,447,638 at July 15, 1996) and
                           obligations to a partnership owned by
                           certain of its shareholders ($367,059 at
                           July 15, 1996) (collectively, the
                           "Shareholder Debt"). Based on the April 10,
                           1996 closing price (the day prior to signing
                           the Asset Purchase Agreement) of $18.88 per
                           share, the aggregate market value of the
                           shares of Duramed Common Stock and the
                           Warrants to be issued in the Transaction
                           would have been approximately $12,940,000
                           (assuming a fair market value of $2.15 per
                           Warrant, as determined by an independent
                           appraiser retained by Duramed).
    

PLAN OF LIQUIDATION...     Pursuant to the Plan of Liquidation,
                           Hallmark will distribute a portion of
                           the Duramed Common Stock (or cash
                           obtained upon the sale of such stock) to
                           its creditors as payment in full of its

                                      - 3 -

<PAGE>   15
   


                           obligations, other than those to be
                           assumed by Duramed.  Hallmark estimates
                           that approximately 113,834 shares of
                           Duramed Common Stock and 400,000
                           Warrants will be available for
                           distribution to its shareholders.
    
   

OUTSTANDING DURAMED
COMMON STOCK...........    As of July 15, 1996, there were
                           outstanding 10,687,821 shares of Duramed
                           Common Stock.  In the Transaction,
                           640,000 shares of Duramed Common Stock
                           will be issued (1,040,000 shares if all
                           Warrants are exercised), which would
                           represent approximately 6.0% (9.7% if
                           all Warrants are exercised) of such
                           outstanding Duramed Common Stock.
    

DURAMED'S REASONS
FOR THE TRANSACTION....    Duramed desires to complete the
                           Transaction because it will bring to
                           Duramed a research and development
                           pipeline which includes controlled
                           release technology.  Duramed believes
                           that combining Duramed and Hallmark
                           product development programs will
                           position Duramed for long-term growth
                           through the introduction of products
                           requiring sophisticated technology.

RECOMMENDATION OF
HALLMARK'S BOARD OF
DIRECTORS..............    The Board of Directors of Hallmark
                           ratified the Transaction at its April
                           12, 1996 Board Meeting and unanimously
                           recommends that Hallmark shareholders
                           vote in favor of the Transaction.  See
                           "SPECIAL FACTORS -Background and Reasons
                           for the Plan of Liquidation and the
                           Transaction" and "SPECIAL FACTORS --
                           Recommendation of Hallmark Board of
                           Directors."

CLOSING OF THE
TRANSACTION............    It is expected that the Transaction will
                           be consummated as promptly as
                           practicable after the requisite approval
                           of Hallmark's shareholders has been
                           obtained and all other conditions to the
                           Transaction have been satisfied or
                           waived.  See "THE TRANSACTION --
                           Conditions; Waivers."

                               MARKET INFORMATION

   

         During the 1994 period prior to September 16, 1994, the Duramed Common
Stock was traded in the over-the-counter market due to Duramed's inability to
meet certain listing requirements of the Nasdaq National Market ("Nasdaq"). On
September 16, 1994, trading of the Duramed Common Stock on the Nasdaq
recommenced under a listing exception from the Nasdaq's tangible net asset
requirements. On December 12, 1995 Duramed was notified that it was found to be
in compliance with all Nasdaq requirements, and the exception was removed. The
table below sets forth the high and low trades for the Duramed Common Stock as
reported by the Nasdaq. Quotations prior to September 16, 1994 are the high and
low bid quotations as reported by the National Quotation Bureau, Inc. and

         As of July 15, 1996, Duramed had 1,185 stockholders of record. Duramed
has not paid any cash dividends on its Common Stock since its inception and does
not intend to pay cash dividends in the foreseeable future. Under the terms of
Duramed's current loan agreements with its bank, no dividend declaration is
permitted. In addition, the terms of Duramed's loan agreement with the State of
Ohio require that Duramed not pay any dividends to its stockholders unless an
amount equal to 30% of such dividends is paid to the State of Ohio as an
additional principal reduction.

         Duramed does not intend to list the Warrants for trading on Nasdaq or
any stock exchange. There can be no assurance that any over-the-counter trading
market for the Warrants will develop.

         Hallmark Common Stock is held of record by 53 persons and no trading
market for Hallmark Common Stock exists. Hallmark has not paid any cash
dividends on its Common Stock since its inception and does not intend to pay
cash dividends in the foreseeable future. Under the terms of Hallmark's current
loan agreements with its bank, no dividend declaration is permitted.
   

         On October 9, 1995, the last full day of trading before the issuance of
a press release by Duramed and Hallmark announcing that they had entered into a
letter of intent for the acquisition of Hallmark by Duramed, the reported
closing price per share of Duramed Common Stock was $13.88. On April 10, 1996,
the last full day of trading immediately preceding the public announcement of
the signing of the Asset Purchase Agreement the closing price of Duramed Common
Stock was $18.88. On August 5, 1996, the closing price per share of Duramed
Common Stock was $14.375.
    
   

                                  RECENT EVENTS

         On August 7, 1996, Duramed completed the issuance of 200,000 shares of
Series D Convertible Preferred Stock. The net proceeds of this offering of
approximately $19 million will be directed primarily toward Duramed's new
product development activities. Beginning October 16, 1996, the Series D
Preferred Shares are convertible at the option of the holders at 15% below the
average closing bid price of the common shares of the Company over the 10-day
trading period ending two days prior to the date of conversion (the "conversion
price"). No more than 2,130,895 common shares will be issued upon conversion,
and any Series D Shares which remain outstanding after the issuance of such
maximum number of common shares would not be converted but would be subject to
cash redemption at a redemption price designed to yield the same economic
benefit to the holders as the conversion price. The conversion price for the
Series D Preferred Shares may not be less than $7 per share, nor more than $20
per share. Series D Preferred Shares will pay a dividend of 8% annually, payable
quarterly in arrears, on all unconverted Preferred Shares. Any of the Series D
Preferred Shares which remain outstanding will be converted (or redeemed) 
automatically on July 18, 1998.
    

         Under the terms of agreements with Ortho-McNeil Pharmaceutical
Corporation, Duramed has non-exclusive distribution rights to the Ortho-McNeil
products Acetaminophen with Codeine, Tolmetin Sodium, Tolmetin Sodium DS,
Oxycodone with Acetaminophen and Estropipate. The term of the distribution
agreement for each of these products is ten years subject to reduction to three
years (if not extended) from date of first sale if the Duramed's conjugated
estrogens product has not been 
                                     - 11 -
<PAGE>   23
   

approved by the FDA by June 30, 1996. Such approval was not received by June 30,
1996. Duramed commenced marketing Estropipate during the fourth quarter of 1993
and the other Ortho-McNeil products during the fourth quarter of 1994. Duramed
is discussing an extension of these rights with Ortho-McNeil. Loss of these
distribution rights would be likely to have an adverse effect upon the Company's
results of operations. 
    

   
         As indicated in Duramed's Form 10-Q for the quarter ended March 31,
1996, Duramed has experienced a decline in the sales price of certain of its
products including its Methylprednisolone product. While net sales and gross
margins in the second quarter of 1996 are expected to exceed the first quarter
levels this is primarily attributable to unit increases of Duramed's
Methylprednisolone product resulting from the seasonal nature of the product.
Operating expenses increased in the second quarter as a result of increased
product development expenses. Duramed expects to report a pre-tax loss in the
second quarter in line with the first quarter. The competitive environment is
expected to remain intense which may result in further declines in the sales
prices of certain of Duramed's products including Methylprednisolone.

         As of March 31, 1996, Duramed had a net deferred tax asset of $3.9 
million. Full utilization of this deferred tax benefit would require future
taxable income of $10.3 million. Duramed evaluates the valuation of its deferred
tax asset on a quarterly basis. The evaluation excludes forecasted profits from
products under development or on file with the Food and Drug Administration.
Given Duramed's operating performance with its current product line and planned
expenditures resulting from its commitment to an expanded product development
program, Duramed may restore the valuation reserve associated with the deferred
tax asset which would result in a non-cash charge to earnings for the quarter
during which such action is taken.

SPECIAL MEETING
   

         This Proxy Statement/Prospectus is being furnished to Hallmark
shareholders in connection with the solicitation of proxies (the "Proxy
Solicitation") by the Board of Directors of Hallmark for use at a Special
Meeting of Shareholders of Hallmark to be held on September 11, 1996, 
commencing at 1:00 p.m., local time, at 400 Campus Drive, Somerset, New Jersey
and at any adjournments or postponements thereof (the "Special Meeting").
    
   

         At the Special Meeting, Hallmark shareholders will consider and vote
upon a proposal to approve the proposed Plan of Liquidation and Dissolution of
Hallmark (the "Plan") providing for the sale of substantially all of the assets
of Hallmark to Duramed (the "Transaction") pursuant to the terms of the Asset
Purchase Agreement dated as of April 9, 1996 between Hallmark and Duramed (the
"Asset Purchase Agreement"). Pursuant to the Asset Purchase Agreement, upon
consummation of the Transaction, Duramed will acquire substantially all of the
assets of Hallmark and will assume certain of Hallmark's liabilities, including
its bank indebtedness and certain of its accounts payable, and Hallmark's
indebtedness to Duramed ($3,480,520 at July 15, 1996) will be released. Duramed
will issue an aggregate of 640,000 shares of Duramed Common Stock and warrants
to purchase 400,000 shares of Duramed Common Stock at $25.00 per share (the
"Warrants") as consideration for the Transaction. Pursuant to the Plan of
Liquidation, Hallmark will distribute a portion of the Duramed Common Stock (or
cash obtained upon the sale of such stock) to its creditors as payment in full
of its obligations, other than those to be assumed by Duramed. Hallmark
estimates that approximately 113,834 shares of Duramed Common Stock and 400,000
Warrants will be available for distribution to its shareholders.
    

         Holders of Hallmark Common Stock who do not vote in favor of the
Transaction and who perfect their rights in accordance with the requirements of
New Jersey Law will be entitled to demand


                                     - 13 -

appraisal rights as a result of the Transaction. See "THE TRANSACTION -- 
Appraisal Rights."

RECORD DATE; SHARES ENTITLED TO VOTE; VOTE REQUIRED
   

         The close of business on July 15, 1996 (the "Record Date") has been
fixed as the record date for determination of the holders of Hallmark Common
Stock who are entitled to notice of, and to vote at, the Special Meeting. As of
the Record Date, there were 6,156,240 shares of Hallmark Common Stock
outstanding. The holders of record of shares of Hallmark Common Stock on the
Record Date are entitled to one vote per share on each matter submitted to a
vote at the Special Meeting. The presence in person or by proxy of the holders
of a majority of the outstanding shares of Hallmark Common Stock entitled to
vote is necessary to constitute a quorum for the transaction of business at the
Special Meeting. Under the New Jersey Business Corporation Law ("NJBCL"), the
holders of a majority of the outstanding shares of Hallmark Common Stock must be
voted in favor of the Transaction for it to be approved. The Asset Purchase
Agreement also provides that the Transaction must be approved by the affirmative
vote of the holders of a majority of the outstanding shares of Hallmark Common
Stock actually voting on the proposal, other than shares of Hallmark Common
Stock beneficially owned by Duramed or its affiliates (collectively, the
"Required Company Vote"). As of the Record Date, Duramed and its affiliates
owned no shares of Hallmark Common Stock. Certain directors of Hallmark, who
owned 3,870,493 shares of Hallmark Common Stock as of the Record Date,
constituting approximately 63% of the outstanding Hallmark Common Stock, have
agreed to vote in favor of the Transaction.
    


PROXIES; PROXY SOLICITATION

         Shares of Hallmark Common Stock represented by properly executed
proxies received at or prior to the Special Meeting and which have not been
revoked will be voted at the Special Meeting in accordance with the instructions
contained therein. Shares of Hallmark Common Stock represented by properly
executed proxies for which no instruction is given will be voted FOR approval of
the Transaction. Hallmark shareholders are requested to complete, sign, date and
return promptly the enclosed proxy in the postage prepaid envelope provided for
this purpose in order to ensure that their shares are voted. A shareholder may
revoke a proxy by submitting at any time prior to the vote on the Transaction a
later dated proxy with respect to the same shares, by delivering written notice
of revocation to the Secretary of Hallmark at any time prior to such vote or by
attending the Special Meeting and voting in person. Attendance at the Special
Meeting will not in and of itself revoke a proxy.


                                     - 14 -
<PAGE>   26

         If fewer shares of Hallmark Common Stock are voted in favor of approval
of the Transaction than the number required for approval, it is expected that
the Special Meeting will be postponed or adjourned for the purpose of allowing
additional time for obtaining additional proxies or votes, and, at any
subsequent reconvening of the Special Meeting, all proxies will be voted in the
same manner as such proxies would have been voted at the original convening of
the meeting (except for any proxies which have theretofore been revoked or
withdrawn), notwithstanding that they may have been voted on the same or any
other matter at a previous meeting.

         Hallmark will bear the cost of the solicitation of proxies from its
shareholders. In addition to solicitation by mail, directors, officers and
employees of Hallmark and Duramed may solicit proxies by telephone, facsimile or
otherwise. Such directors, officers and employees of Hallmark and Duramed will
not be additionally compensated for such solicitation but may be reimbursed for
out-of-pocket expenses incurred in connection therewith.

                                 SPECIAL FACTORS

BACKGROUND OF AND REASONS FOR THE PLAN OF LIQUIDATION AND THE
TRANSACTION

         Hallmark was organized in 1992 and by May 1995 had developed commercial
readiness for the production and sale of initial products. Hallmark's
manufacturing facility had been constructed, ANDA's for Captopril and Glipizide
had been filed and several other products were under development. Hallmark's
Board of Directors determined that it needed substantial additional expansion
capital to enable Hallmark to commercialize its products. Accordingly, Hallmark
decided to seek a strategic partner.

         During the spring of 1995, Duramed and Hallmark engaged in discussions
concerning the marketing of Hallmark's drug, Captopril. During the summer of
1995, these discussions extended beyond the marketing and distribution of
Captopril into discussions concerning a possible merger. Due diligence commenced
during the summer of 1995 culminating in a Letter of Intent in October 1995 as
described below.

         Hallmark's initial research and development efforts were directed
primarily toward immediate release solid oral dosage form drugs. Based on
changing market conditions and its experience with immediate release solid oral
dosage form drugs, the Board of Directors of Hallmark determined in early 1994
to expand its research and development efforts into sustained release solid oral
dosage form drugs.


                                     - 15 -
<PAGE>   27

         In order to fund Hallmark's expansion of its research and development
efforts into sustained release solid oral dosage form drugs, Hallmark considered
several alternatives including (1) an initial public offering; (2) additional
debt and equity financing from existing stockholders; (3) strategic partners
willing to invest expansion capital; and (4) product joint ventures. In order to
provide immediate capital, Hallmark sought equity financing from its
stockholders during the summer of 1994. Hallmark raised approximately $7,500,000
during that offering. Hallmark also explored during that time strategic partners
and product joint ventures with various pharmaceutical companies although no
such arrangements were consummated.

         During the fall of 1994, Hallmark contacted several financial advisory
firms for assistance in raising capital to fund its research and development
expansion efforts. Hallmark engaged three financial advisory firms in late 1994
to assist it in raising capital: Commercial Financial Corporation, Joseph A.
Watters and Windward Partners. In January 1995, the Board of Directors
terminated those engagements after they proved unsuccessful. At that time, the
Board of Directors determined (i) to engage Deloitte & Touche, LLP to identify
potential financing sources and (ii) to seek bridge financing from Hallmark's
existing stockholders until financing sources were identified. Hallmark raised
$3 million from its stockholders in early 1995 through the issuance of notes.
Hallmark terminated its relationship with Deloitte & Touche in August 1995 after
its financing efforts proved to be unsuccessful.

         In September 1995, Hallmark received a proposal on behalf of an
European pharmaceutical company expressing an interest in a $15 million equity
investment in Hallmark in exchange for a controlling interest in the Company and
requesting an exclusive negotiating period. The Hallmark Board of Directors
declined to grant an exclusive negotiating period but consented to due
diligence. In October 1995, the Hallmark Board of Directors retained Armata
Partners, an investment banking firm, to assist the Board in evaluating
alternative proposals. After exploring all alternative proposals, the Board of
Directors determined to proceed with the Duramed proposal.

         Discussions with Duramed continued and in early October, 1995, Duramed
and Hallmark entered into a Letter of Intent which contemplated that Duramed
would acquire Hallmark in a merger in exchange for approximately $30.5 million
in Duramed Common Stock based on future market value (but not more than
1,250,000 shares of Duramed Common Stock). The purchase price was to be paid in
two installments, 50% at closing and 50% on February 15, 1996. 20% of the
consideration was to be held in escrow for a period of 18 months. The Letter of
Intent also contemplated that Duramed would assume Hallmark's bank debt and
repay the Hallmark Shareholder Debt (then approximately $5,800,700). Duramed
agreed to advance Hallmark $100,000 immediately and up to $400,000 per 


                                     - 16 -
<PAGE>   28

month thereafter to finance Hallmark's operations, and Hallmark granted Duramed
exclusive marketing rights in North America to Hallmark's Captopril product. The
transaction was to be subject to customary conditions, including completion of
due diligence, execution of definitive agreements and consummation of the merger
on or before January 31, 1996.

         Negotiations and due diligence continued into December 1995. However,
in mid-December, Duramed advised Hallmark that it was unable to proceed with the
transaction at that time because of uncertainties relating to claims asserted by
Deloitte & Touche, LLP for fees in connection with the transaction, which fees
Duramed was unwilling to assume. In addition, unexpectedly intense competition
with generic Captopril products produced by other manufacturers dramatically
eroded margins on sales of Hallmark's Captopril product and, in Duramed's view,
substantially impaired the value of Hallmark.

         Negotiations resumed in late February 1996 and in early March 1996,
Hallmark and Duramed entered into a revised Letter of Intent which incorporated
the terms of the current Transaction. The revised terms reflected Duramed's
views as to the decreased value of Hallmark and Duramed's refusal to assume any
liability to Deloitte & Touche. After further negotiations, the parties entered
into the Asset Purchase Agreement and other definitive documentation on April
11, 1996 (as of April 9, 1996).

DESCRIPTION OF REASONS FOR BUSINESS COMBINATION WITH DURAMED

         The Hallmark Board of Directors unanimously approved and authorized the
Transaction and recommends approval of the Transaction by Hallmark shareholders
based on the Hallmark Board's determination that the aggregate consideration to
be received by the Hallmark shareholders is fair to them from a financial point
of view and the Transaction is in the best interests of Hallmark, its
shareholders and its nonshareholder constituencies. In making its recommendation
and those determinations, the Hallmark Board of Directors considered the advice
of its management, its financial advisor and legal counsel and the following
factors:

                  (a) The strategic and synergistic effect of a business
combination with Duramed including the compatibility of management teams;
Duramed's established sales and marketing infrastructure; Duramed's customer
base and Duramed's ability to access global marketing opportunities.

                  (b) The lack of operating capital for Hallmark's continued
research and development efforts and Hallmark's absence of sales and marketing
personnel and lack of funds to establish a sales force.


                                     - 17 -
<PAGE>   29

                  (c) The desire of Hallmark shareholders to realize liquidity
in their investment and the unwillingness of Hallmark shareholders to invest
further in Hallmark or to continue to guarantee Hallmark's indebtedness.

                  (d) The existence of a public market for Duramed's common
stock, the trading history of Duramed common stock and Duramed's ability to
continue to access the public markets for funding of business expansion.

                  (e) Information with respect to the management, business
operations, financial condition, financial performance, and business and
financial prospects of Duramed as well as the likelihood of achieving those
prospects compared to the going-concern value of Hallmark as reflected by its
historical operating results.

                  (f) The likelihood that the Transaction would be
consummated, including the experience, reputation and financial
capability of Duramed.

                  (g) The risks associated with Hallmark's ability to locate a

RECOMMENDATION OF HALLMARK BOARD OF DIRECTORS

         The Board of Directors of Hallmark unanimously recommends that
shareholders of Hallmark vote in favor of the Transaction (see "SPECIAL FACTORS
- -- Background of and Reasons for the Transaction).

INTERESTS OF CERTAIN PERSONS
   

         Hallmark Leasing Associates, a partnership owned by certain of
Hallmark's shareholders and directors ("HLA"), leases certain equipment to
Hallmark pursuant to agreements dated September 1, 1992, November 16, 1992,
March 20, 1993, May 17, 1994 and December 28, 1994 (the "Lease Agreements"). The
aggregate annual rental payments under the Lease Agreements are $454,564. At
July 15, 1996, $140,000 of such rental obligations that had become due were
unpaid. Pursuant to an agreement dated as of April 9, 1996 between HLA and
Duramed (the "HLA Agreement"), HLA agreed to sell such equipment to Duramed at
the closing of the Transaction for a purchase price of approximately $494,000,
which is equal to its net book value as of the date of execution of the HLA
Agreement. The Lease Agreements will be canceled, and Duramed will not assume
any liability for unpaid rental obligations.
    


                                     - 18 -
<PAGE>   30
   

         Pursuant to various transactions over the last three years, Hallmark
has borrowed funds from HLA and certain of its shareholders. The outstanding
balance of such indebtedness to HLA at July 15, 1996 was $227,059. Duramed will
not assume any obligation of Hallmark with respect to such indebtedness to HLA
or the shareholders. Pursuant to the Plan, such creditors will be paid in full
by Hallmark from the proceeds of the Transaction, in shares of Duramed Common
Stock or in cash.
    
   

         Certain shareholders and directors of Hallmark have guaranteed
indebtedness of Hallmark to Mid-State Bank in the aggregate amount of
approximately $1,672,000, of which approximately $1,256,351 was still owed at
July 15, 1996. Duramed has agreed to cause all such indebtedness to be repaid at
the closing of the Transaction (the "Closing").
    

         Two Hallmark directors have also guaranteed certain of Hallmark's
obligations in connection with its lease of computer equipment, which lease will
be assumed by Duramed. Duramed has agreed to use all reasonable efforts to
obtain the release of such guarantees and to indemnify such directors against
any claims pursuant to such guarantees if they are not released.
   
         Pursuant to the Asset Purchase Agreement, Duramed will assume
Hallmark's obligations under employment agreements with Mr. V. G. Budharaju,
President and Chief Executive Officer of Hallmark, Dr. Kamlesh Shah, Hallmark's
Director of Research and Development, and Dr. Guohua Zhang, Hallmark's Director
of Research and Development and Special Projects. Each of these agreements
provides for a five-year term, specified base salary ($150,000 for Mr. Raju and
approximately $105,000 for each of Drs. Shah and Zhang), other benefits and
grants of Hallmark Common Stock all of which Common Stock has been granted. 
    
   
         Prior to the execution of the Asset Purchase Agreement, Duramed
advanced $2,085,012 in product development costs to Hallmark in exchange for
product marketing rights to Captopril and another generic prescription
pharmaceutical product. Pursuant to the Asset Purchase Agreement, since April 1,
1996, Duramed has advanced to Hallmark amounts necessary to meet Hallmark's
operating expenses and interest payments to its bank at a rate not exceeding an
aggregate of $314,000 per month. Accordingly, at July 15, 1996, Hallmark owed
Duramed $3,480,520, represented by promissory notes, certain of which notes are
secured by Hallmark's rights in Captopril and such other product. The Asset
Purchase Agreement provides that such indebtedness will be released at the
Closing. If the Transaction is not consummated, Hallmark will be obligated to
repay such amounts to Duramed.
    

         The Asset Purchase Agreement also provides that under certain
circumstances Duramed will advance to Hallmark additional funds to pay all
reasonable costs of its biostudy with respect to 


                                     - 19 -

<PAGE>   31
   

such other product. By July 15, 1996, Duramed had advanced $245,508 towards the
cost of this biostudy, which amount is included in the $3,480,520 owed by
Hallmark to Duramed at that date.
    
   

         As of July 12, 1996, Duramed agreed to advance to Hallmark up to
$290,000 to cover the costs of its biostudy with respect to a third generic
prescription pharmaceutical product, in exchange for product marketing rights to
such product. As of July 15, 1996, Duramed had advanced no funds to Hallmark
toward the cost of this biostudy.
    
   

         As of July 8, 1996, Duramed issued options to purchase an aggregate of 
75,000 shares of common stock to certain consultants and employees of Hallmark
including V. G. Budharaju, Guohua Zhang, Kamlesh B. Shah, Mike Adone, Leonid
Freytor and Vijay R. Dandu. The options will be exercisable at $15.50, the
market price of Duramed common stock as of July 8, 1996. The options will vest
over a five year period contingent upon the individuals continuing to provide
services, either as consultants or employees, during the vesting period.
    

                                 THE TRANSACTION

         The descriptions of the Plan and the Asset Purchase Agreement set forth
in this section do not purport to be complete and are qualified in their
entirety by reference to the Plan and the Asset Purchase Agreement, which are
attached as Appendices A and B, respectively, to this Proxy Statement/Prospectus
and are incorporated by reference herein.

SALE OF THE ASSETS

         At the Closing, Duramed will purchase all of Hallmark's right, title

"Hallmark Pharmaceuticals, Inc." and all goodwill.

PURCHASE PRICE

         At the Closing, Duramed will issue 640,000 shares of Duramed Common

escrow as described below. Hallmark will distribute the shares and Warrants as
provided in the Plan. Duramed will also assume certain obligations of Hallmark,
including those arising under assigned contracts, agreements and leases, certain
specified accounts payable and Hallmark's bank 


                                     - 20 -

debt ($1,256,351 at July 15, 1996), and will release all of Hallmark's
indebtedness to Duramed ($3,480,520 at July 15, 1996). Duramed will not assume
any other liabilities of Hallmark, including any potential obligation of
Hallmark to pay a finder's fee to Deloitte & Touche, LLP in connection with the
Transactions, any Hallmark Shareholder Debt, any obligation relating to any
stock options issued by Hallmark, any obligation under any Hallmark employee
benefit plan, any Hallmark obligation for taxes or any liability to any Hallmark
shareholder exercising appraisal rights.
    

ESCROW

         At the Closing, the parties will enter into an agreement (the "Escrow
Agreement") providing that 10% of the Duramed Common Stock and the Warrants to
be issued will be placed in escrow (the "Escrow") with The Provident Bank (the
"Escrow Agent") for a period of 12 months, as security for Hallmark's
obligations to Duramed with respect to its representations, warranties and
covenants in the Asset Purchase Agreement. The Escrow Agreement permits Hallmark
to cause the sale of all or part of such securities, in which event the proceeds
of sale will be held in the Escrow.

CLOSING OF THE TRANSACTION

         If the Transaction is approved by the requisite vote of Hallmark
shareholders and the other conditions to the Transaction are satisfied or waived
(where permissible), the Closing will be held as soon as practicable after the
Special Meeting. It is presently contemplated that the Closing will occur
promptly after obtaining the necessary approval of Hallmark shareholders. See

         Hallmark has agreed to use all reasonable efforts to conduct its

         The respective obligations of Hallmark and Duramed to effect the

the Closing, including: (a) approval of the Transaction by the holders of (i) a
majority of the outstanding shares of Hallmark Common Stock, and (ii) a majority
of the outstanding shares of Hallmark Common Stock actually voted on the
Transaction, other than shares of Hallmark Common Stock beneficially owned by
Duramed or its affiliates; (b) no court or governmental or regulatory authority
of competent jurisdiction having been enacted, issued, promulgated, enforced or
entered any statute, rule, regulation, judgment, decree, injunction or other
order or taken any action prohibiting or seeking to prohibit or adversely affect

Agreement; (c) the absence of any stop order suspending the effectiveness of the
Registration Statement on Form S-4 of which this Proxy Statement/Prospectus is a

                                     - 23 -
<PAGE>   35

the Asset Purchase Agreement and the consummation of the transactions
contemplated thereby, having been made or obtained without restrictions; (e) the
closing of the transaction contemplated by the HLA Agreement; and (f) the
execution of the Escrow Agreement.

         The obligations of Duramed and Hallmark to effect the Transaction are
also subject to certain conditions which are normal and customary for
transactions such as the Transaction, including, in the case of Duramed's
obligations, compliance by Hallmark with the New Jersey Industrial Site Recovery
Act and the Employment Agreements being in full force and effect.

         The Asset Purchase Agreement provides that any or all conditions to any
party's obligations may, at any time prior to the Effective Time, be waived by
such party in whole or in part, to the extent permitted by applicable law.

AMENDMENT; TERMINATION

         At any time prior to the Closing, Duramed and Hallmark may amend the
Asset Purchase Agreement by mutual written agreement.

         The Asset Purchase Agreement may be terminated at any time prior to the
Closing: (a) by mutual consent of Duramed and Hallmark; (b) by either Duramed or
Hallmark if the Transaction shall not have been consummated by September 30,
1996; (c) by either Duramed or Hallmark if the other is in material breach of
any representation, warranty, covenant and agreement which has not been cured in
a specified time period after notice; (d) by either Duramed or Hallmark if any
permanent injunction or other order of a court or other competent authority
enjoining or otherwise preventing the consummation of the transactions
contemplated by the Asset Purchase Agreement shall have become final and
non-appealable; (e) by either Duramed or Hallmark if the Required Company Vote
shall not have been obtained; (f) by Duramed if the Board of Directors of
Hallmark shall or shall resolve to (i) not recommend, or withdraw its approval
or recommendation of, the Asset Purchase Agreement or any of the transactions
contemplated hereby, (ii) modify such approval or recommendation in a manner
adverse to Duramed or any of its affiliates or (iii) adopt a Third-Party
Resolution (as defined below); or (g) by Hallmark if an entity or group (other
than Duramed or any of its affiliates) (a "Third Party") shall have made a bona
fide proposal (a "Third-Party Proposal") to acquire all or a substantial portion
of the outstanding shares of Hallmark Common Stock or the assets of Hallmark and
the Board of Directors of Hallmark adopts a resolution (a "Third-Party
Resolution") that states that it believes in good faith that such a proposal is
more favorable, from a financial point of view, to the holders of Hallmark
Common Stock than the Transaction. Hallmark is required, prior to such
termination, to provide 


                                     - 24 -
<PAGE>   36

Duramed with notice of the terms and conditions of such Third-Party Proposal and
the identity of such Third Party.

ACCOUNTING TREATMENT

         It is expected that the Transaction will be accounted for by Duramed as
a purchase.

INDEMNIFICATION

         Hallmark has agreed to indemnify Duramed for any damages resulting from
any misrepresentation or breach of warranty by Hallmark or any Hallmark
liability not assumed by Duramed. Duramed may assert an indemnification claim
within one year after the Closing and only to the extent of the shares of
Duramed Common Stock, Warrants and proceeds therefrom held in the Escrow.
Duramed has agreed to indemnify Hallmark in certain circumstances, including for
any breach of warranty by Duramed or any Hallmark liability specifically assumed
by Duramed.

TREATMENT OF HALLMARK STOCK OPTIONS

         Hallmark currently has outstanding options to purchase 1,500,000 shares
of its Common Stock at an exercise price of $1.00 per share, and options to
purchase 620,100 shares of its Common Stock at an exercise price of $5.00 per
share. All of the outstanding options are currently exercisable. In connection
with this proxy solicitation, Hallmark will notify all persons holding options
to purchase common stock of the Transaction, giving them a period of not less
than 30 days from the date of the notice in which to exercise their options and
participate in the Transaction as shareholders. Options that are not exercised
within 30 days of the notice will be canceled.

EXPENSES AND FEES

         Except as described below, each party to the Asset Purchase Agreement
will pay its own expenses in connection with the Transaction. If the Transaction
is consummated, Duramed also will assume and pay $50,000 of the fees of Armata
Partners, financial advisor to Hallmark. If the Asset Purchase Agreement is
terminated due to (i) failure by Hallmark to obtain the approval of Hallmark
shareholders, (ii) a determination by the Hallmark Board of Directors to pursue
a transaction with a Third Party, (iii) failure to consummate the transaction
contemplated by the HLA Agreement or (iv) breach by Hallmark of any of its
representations, warranties and agreements under the Asset Purchase Agreement,
Hallmark has agreed to pay all actual out-of-pocket fees and expenses incurred
by Duramed in connection with the Transaction, up to $500,000.

         If the Asset Purchase Agreement is terminated for any reason (other
than its material breach by Hallmark), Hallmark may 


                                     - 25 -
<PAGE>   37

repurchase all marketing rights to its products which have been granted to
Duramed by repaying all funds previously advanced by Duramed.

CERTAIN FEDERAL INCOME TAX CONSEQUENCES

         THE TRANSACTION. The Transaction will constitute a taxable sale. In
accordance with section 1060 of the Internal Revenue Code (the "Code"), to
determine the amount and character of the gain or loss recognized by Hallmark as
the result of the sale, the consideration paid by Duramed must be allocated
among the assets sold. Hallmark will recognize a gain under section 1001(a) of
the Code on the sale of an asset to the extent the consideration allocated to
the asset exceeds Hallmark's basis in the asset. Hallmark will recognize a loss
under section 1001(a) of the Code on the sale of an asset to the extent
Hallmark's basis in the asset exceeds the fair market value of the consideration
allocated to the asset.

         Hallmark currently has net operating losses and net operating loss
carryovers that can be applied against, and thereby reduce or eliminate, gains
recognized by Hallmark as a result of the Transaction.

         ESCROW FUND. Hallmark will be treated for tax purposes as the owner of
the Escrow Fund. Consequently, income from the securities or cash held in the
Escrow Fund will be included in Hallmark's taxable gross income.

         PAYMENT OF LIABILITIES WITH DURAMED COMMON STOCK. Assuming the fair
market value of the shares of Duramed Common Stock does not change from the time
Hallmark receives them until Hallmark transfers a portion of them to its
creditors, such transfer will not result in any tax consequences to Hallmark. If
during such time the fair market value of the Duramed Common Stock transferred
to the creditors does change, Hallmark will recognize taxable gain or loss equal
to such change.

        The transfer of Duramed Common Stock to Hallmark's creditors may cause
some of the creditors to recognize gain. A creditor will recognize gain to the
extent that the fair market value of the portion of the Duramed Common Stock
received by the creditor exceeds the creditor's basis in Hallmark's
indebtedness to the creditor. Although a creditor's basis in a debt owed the    
creditor is generally equal to the amount of the debt, under certain
circumstances the creditor's basis may be less than the amount of the debt. One
such circumstance may arise where the creditor is a shareholder of the debtor,
and the debtor is an S corporation at any time during which the debt is
outstanding. In such a case, in accordance with section 1367(b)(2) of the Code
the creditor's basis in the indebtedness of the S corporation to the creditor
may be reduced under certain circumstances including 


                                     - 26 -
<PAGE>   38

the recognition of losses and deductions by the S corporation when the
shareholder's basis in his stock is zero.

         Hallmark was at one time an S corporation. During such time, some of
the creditors' bases in the debts owed them by Hallmark were reduced.
Consequently, such creditors will recognize gain upon Hallmark's satisfaction of
the debts owed them.

         LIQUIDATION OF HALLMARK. Hallmark will not recognize any gain or loss
as a result of its liquidation unless the fair market value of the Duramed
Common Stock and Warrants changes from the time of their transfer to Hallmark to
the time of Hallmark's transfer of them to its shareholders. If the fair market
value of the Duramed Common Stock and Warrants does change during such time,
then under section 336(a) of the Code, Hallmark will recognize gain or loss
(recognition of loss is limited under certain circumstances) equal to the
difference between its basis in the Duramed Common Stock and Warrants (their
fair market value when received by Hallmark) and the fair market value of the
Duramed Common Stock and Warrants on the date they are distributed to the
shareholders.

         In accordance with sections 331 and 1001(a) of the Code, each
shareholder's gain or loss resulting from the liquidation of Hallmark will equal
the difference between the adjusted basis the shareholder has in his stock in
Hallmark and the fair market value of the liquidating distribution received by
the shareholder. Because Hallmark was at one time an S corporation, the basis
that a shareholder holds in his stock in Hallmark may be lower than the fair
market value of the property that the shareholder contributed to Hallmark in
exchange for his stock. While Hallmark was an S corporation, the basis that a
shareholder had in his stock in Hallmark was reduced in accordance with section
1367(a)(2) of the Code under certain circumstances including distributions by
the corporation to the shareholder and as a result of corporate losses and
deductions.

         Any gain or loss recognized by a shareholder as the result of the
shareholder's receipt of assets in the liquidation of Hallmark will be
characterized as a capital gain or loss if the shareholder held his stock in
Hallmark as a capital asset. This gain or loss will be short-term if the
shareholder held his shares in Hallmark for not more than one year, and
long-term if the shareholder held the shares for more than one year.

         Under section 334(a) of the Code, the shareholders will receive a basis
in the assets distributed to them in liquidation of Hallmark equal to the fair
market value of the assets at the time they are distributed.

         EXERCISE OR LAPSE OF WARRANTS. The shareholders of Hallmark will not
recognize any income on the receipt of Duramed Common


                                     - 27 -
<PAGE>   39

Stock pursuant to the exercise of the Warrants. Upon a shareholder's exercise of
the Warrants, the shareholder's basis in the Warrants will be added to the
exercise price to determine the shareholder's basis in the stock received
pursuant to the exercise of the Warrants. Rev. Rul. 78-182, 1978-1 C.B. 265. If
a shareholder chooses not to exercise his Warrants and they lapse, in accordance
with section 1234 of the Code, the shareholder will recognize a loss in an
amount equal to his basis in the Warrants.

THE FOREGOING DISCUSSION IS INTENDED ONLY AS A SUMMARY OF CERTAIN FEDERAL INCOME
TAX CONSEQUENCES OF THE PLAN AND THE TRANSACTION AND DOES NOT PURPORT TO BE A
COMPLETE ANALYSIS OR LISTING OF ALL POTENTIAL TAX EFFECTS RELEVANT TO A DECISION
WHETHER TO VOTE IN FAVOR OF APPROVAL OF THE PLAN AND THE TRANSACTION. THE
DISCUSSION DOES NOT ADDRESS THE TAX CONSEQUENCES THAT MAY BE RELEVANT TO A
PARTICULAR SHAREHOLDER SUBJECT TO SPECIAL TREATMENT UNDER CERTAIN FEDERAL INCOME
TAX LAWS, SUCH AS DEALERS IN SECURITIES, BANKS, INSURANCE COMPANIES, TAX-EXEMPT
ORGANIZATIONS, NON-UNITED STATES PERSONS AND SHAREHOLDERS WHO ACQUIRED THEIR
SHARES OF HALLMARK COMMON STOCK PURSUANT TO THE EXERCISE OF HALLMARK OPTIONS OR
OTHERWISE AS COMPENSATION, NOR ANY CONSEQUENCES ARISING UNDER THE LAWS OF ANY
STATE, LOCALITY OR FOREIGN JURISDICTION. MOREOVER, THE TAX CONSEQUENCES TO
HOLDERS OF HALLMARK OPTIONS ARE NOT DISCUSSED. THE DISCUSSION IS BASED UPON THE
PROVISIONS OF THE INTERNAL REVENUE CODE, TREASURY REGULATIONS THEREUNDER AND
ADMINISTRATIVE RULINGS AND COURT DECISIONS AS OF THE DATE HEREOF, ALL OF WHICH
ARE SUBJECT TO CHANGE. HALLMARK SHAREHOLDERS ARE URGED TO CONSULT THEIR OWN TAX
ADVISORS CONCERNING THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES OF
THE PLAN AND THE TRANSACTION TO THEM.

RIGHTS OF DISSENTING SHAREHOLDERS

         Shareholders of Hallmark who do not vote in favor of the Transaction
and who perfect their rights as described below will have dissenters' rights
under applicable New Jersey law. Section 14A:11-1 of the New Jersey Business
Corporation Act (the "NJBCA") provides that shareholders may generally dissent
from a sale of substantially all of the assets of the corporation not in the
ordinary course of business, except if (i) the shares held by such shareholder
are listed on a national exchange or held of record by not less than 1,000
shareholders, (ii) the transaction is entered into pursuant to a plan of
dissolution of the corporation which provides for distribution of the net assets
of the corporation to its shareholders in accordance with their interests within
one year after the date of such transaction and the transaction is wholly for
cash, securities so listed or held or cash and such securities; or (iii) the
sale is pursuant to an order of a court of competent jurisdiction.

         A shareholder of Hallmark who wishes to assert his right to dissent
from the adoption of the Plan and approval of the Asset 


                                     - 28 -
<PAGE>   40

Purchase Agreement and receive the fair value of his shares must file with
Hallmark a written notice stating that he intends to demand payment for his
shares if the Plan is adopted. Such notice must be filed with Hallmark prior to
the vote of the shareholders on the Plan. If one or more shareholders file
notices of dissent, and the Plan is nonetheless adopted, Hallmark must, within
ten days of the effective date of such action, send written notice of the
effective date of such action to the shareholders filing such notices. Such
shareholders must then provide to Hallmark, within 20 days of the mailing of
such notice, a written demand for payment of the fair value of the shares held
by them and, within twenty days of the date of such demand, submit the share
certificates held by them for notation thereon of such demand.

         Within ten days after expiration of the period within which a
shareholder may demand payment for his shares, Hallmark must mail to all
shareholders making such a demand the balance sheet and surplus statement of
Hallmark as of the latest available date, and a profit and loss statement for
not less than a 12- month period ended on the date of such balance sheet.
Hallmark may accompany such mailing with a written offer to pay each dissenting
shareholder for his shares at a specified price deemed by Hallmark to be the
fair value thereof. Such offer must be made at the same price to each dissenting
shareholder. If, not later than 30 days after the end of the ten-day period
referred to in this paragraph, Hallmark and any dissenting shareholders agree
upon the fair value of the shares, Hallmark must deliver payment therefor to
such shareholders upon surrender of the certificate or certificates representing
such shares.

         If Hallmark and any dissenting shareholder fail to agree upon a fair
value for the shares within the 30-day period described in the previous
paragraph, any remaining dissenting shareholder may serve upon Hallmark, no
later than 30 days after the expiration of such period, a written demand that it
commence an action in the Superior Court of the State of New Jersey for the
determination of the fair value of the shares. Hallmark must commence such
action no later than 30 days after receipt of such demand, or at any earlier
time that it determines. If Hallmark fails to commence such an action within
such time period, any remaining dissenting shareholder may commence such an
action in the name of Hallmark within sixty days of the expiration of such time
period. All remaining dissenting shareholders must be named as parties to such
an action against their shares quasi in rem. The court must render judgment
against Hallmark and in favor of each shareholder who is a party to the action
for the amount of the fair value of his shares, as determined by the court. In
making such determination, the court may appoint an appraiser to receive
evidence and report to the court on the question of fair value. The court must
also award to each shareholder who is a party to the action interest at an
equitable rate from the date of such shareholder's demand for payment, unless
the court finds 


                                     - 29 -
<PAGE>   41

that the refusal of any dissenting shareholder of an offer by Hallmark pursuant
to the preceding paragraph was arbitrary, vexatious or otherwise not in good
faith, in which case no interest shall be awarded. A judgment for the payment of
the fair value of shares must be payable upon surrender to Hallmark of the
certificates representing such shares. The costs and expenses of such an action
must be determined and apportioned by the court. Each party must pay its own
attorney's fees and expert's fees, unless the court finds that the offer made by
Hallmark pursuant to the preceding paragraph was not made in good faith, in
which case the court may in its discretion award to any dissenting shareholder
who is a party to such action his attorney's and expert's fees.

                         INFORMATION CONCERNING DURAMED

         Duramed currently manufactures and sells a limited line of prescription
generic drug products in tablet, capsule and liquid forms to customers
throughout the United States. Products sold by Duramed include those of its own
manufacture and those which it markets under certain arrangements with other
drug manufacturers. Duramed sells its products to drug wholesalers, private
label distributors, drug store chains, health maintenance organizations,
hospitals, nursing homes, retiree organizations, mail order distributors, other
drug manufacturers, mass merchandisers and governmental agencies. Generic drugs
are the chemical and therapeutic equivalents of brand name drugs which have
gained market acceptance while under patent protection. In general, prescription
generic drug products are required to meet the same governmental standards as
brand name pharmaceutical products and must receive FDA approval prior to
manufacture and sale. Generic drug products are marketed after expiration of
patents held by the innovator company, generally on the basis of FDA approved
Abbreviated New Drug Applications submitted by the generic manufacturers.
Generic drug products typically sell at prices substantially below those of the
equivalent brand name products. The increasing emphasis on controlling health
care costs, the growth of managed care organizations and the significant number
of drugs for which patents will expire in the next few years are expected to
create an opportunity for continued growth in the generic drug market.

                         INFORMATION CONCERNING HALLMARK

BUSINESS

         Hallmark is a development stage company engaged in the research,
development and manufacturing of generic or "off-patent" prescription drugs.
Hallmark also is engaged in the business of developing a proprietary drug
delivery system designed to enable alternate formulation of pharmaceutical
compounds. Hallmark is a New Jersey corporation organized in February, 1992.
Hallmark commenced operations on March 1, 1992.

         Hallmark's primary objective has been to enter the generic drug
industry through the establishment of a research and development facility and
the acquisition of equipment and personnel in order to identify and formulate
generic versions of brand name drugs with expired and expiring patents.

         In June, 1992, Hallmark leased its present 22,751 square feet facility
in Somerset, New Jersey. Modification of part of the building at a cost of
approximately $128,000 for use as a research and development laboratory was
completed in September, 1992. Support staff, consisting of laboratory personnel
and clerical support personnel, were also added in September, 1992.

         The FDA's promulgation of a series of regulatory requirements in the
early 1990's had a material effect on the time and money needed for Hallmark to
achieve its business objective. Chief among these regulatory changes were the
requirements for pre-approval inspections and for submission batch manufacture
in a facility meeting Good Manufacturing Practice ("GMP") regulations. Plans to
modify part of the building as a pilot facility in compliance with GMP
regulations of the FDA were developed and implemented during the latter part of
1992 and early 1993. Implementation costs were approximately $191,000. This GMP
pilot facility was operational in April, 1993.

         Between that latter part of 1993 and early 1994, Hallmark utilized the
GMP facility to complete three bio-studies to support applications by Hallmark
to the FDA for approval of two generic drug products: Captopril (application
filed in March, 1993) and Glipizide (application filed in October, 1994).

         Also beginning in late 1993 and continuing throughout 1994, plans to
modify the rest of the building as an additional GMP facility were developed and
implemented in two phases at a cost of approximately $1,500,000. This facility,
which was completed in the first quarter of 1995, will enable Hallmark to
produce selected drugs in commercial quantities.

         Hallmark is dependent on debt and equity financing to fund its
activities. Hallmark has financed its activities through 


                                     - 31 -
<PAGE>   43

sales of common stock, loans from shareholders and bank loans guaranteed by
shareholders. The aggregate of these financing activities has produced
approximately $14,877,000 through March 31, 1996, all of which has been
dedicated to research and development ("R&D"), acquisition of equipment and
personnel, and operation of Hallmark's facilities.

TIME RELEASE FORMS

         During the process of completing the GMP facility, Hallmark had
concentrated its efforts on immediate release solid oral dosage forms as the
scope of the project. However, based on the earlier success of Hallmark's R&D
program, changes in market conditions, and the desirability of enhancing
Hallmark's product potential, the Board of Directors of Hallmark decided in
October of 1993 to expand the R&D program to include time release solid oral
dosage forms. Dr. Guohua Zhang, Ph.D., a specialist in the development of time
release solid oral dosage drugs, became, on April 18, 1994, the Director of
Special Projects to direct the activities of this expanded R&D program.

         The decision to enter the time release field while continuing with the
immediate solid dosage form products contributed to the need for substantially
more funding. Further, compliance with FDA requirements for pre-approval
inspection and entry into the time release field caused Hallmark to seek and
obtain additional funding in 1994. The total amounts raised through stock sales,
stockholder loans and bank loans guaranteed by stockholders in 1994 was
approximately $5,446,950.

               MANAGEMENT'S DISCUSSION AND ANALYSIS OF RESULTS OF
                 OPERATIONS AND FINANCIAL CONDITION OF HALLMARK

RESULTS OF OPERATIONS

         Comparison of Three Month Periods Ended March 31, 1996 and 1995.

NET SALES AND COST OF GOODS SOLD

         Net sales for the three month period ended March 31, 1996 of $836,819
consisted of sales of Hallmark's Captopril product to Duramed in accordance with
the terms of a distribution agreement between the parties. As a result of
intense competition in the market for the Captopril product, Hallmark incurred a
gross loss of $314,140 and its cost of goods sold was $1,150,959. There were no
sales or cost of goods sold in the comparable prior quarter as Hallmark was in
the development stage at that time.

OPERATING EXPENSES

Research and development

         Research and development expense increased by $114,795, or 27.7%, in
the first quarter of 1996 to $529,484 from $414,689 in the first quarter of
1995. The increase in research and development expense was primarily a result of
increased bio-studies.

General and administrative

         General and administrative expense increased by $10,320, or 3.9%, in
the first quarter of 1996 to $275,564 from $265,244 in the first quarter of
1995. The moderate increase in General and Administrative expense is a result of
first quarter increases in salaries and product liability insurance, offset by a
decrease in legal and professional fees.

Interest Expense

         Interest expense increased by $70,391, or 55.6%, in the first quarter
of 1996 to $197,042 from $126,651 in the first quarter of 1995. The increased
interest expense is principally a result of increased stockholder debt.

         Comparison of Years Ended December 31, 1995 and 1994

NET SALES

         There were no sales in 1995 and 1994 as Hallmark was in the development
stage.


                                     - 34 -
<PAGE>   46

OPERATING EXPENSES

Research and development

         Research and development expense increased by $137,675, or 6.9%, in
1995 to $2,120,982 from $1,983,307 in 1994. The increase in research and
development expense was principally a result of increased salaries as well as
increased outside lab fees for bioequivalency studies.

General and administrative

         General and administrative expense decreased by $25,177, or 2.9%, in
1995 to $856,028 from $881,205 in 1994. The decrease in general and
administrative expense was principally a result of a non-recurring charge of
$250,000 recorded in 1994 in connection with the issuance of stock options (see
Note 8 to Hallmark's financial statements) offset by 1995 increases in legal and
professional fees of approximately $103,400, salaries of approximately $18,200,
insurance and workmen's compensation of approximately $17,300, travel expenses
of approximately $22,000, and net increases in other expenses aggregating
approximately $64,000.

Interest Expense

         Total interest expense increased by $338,718, or 82.8%, in 1995 to
$747,803 from $409,085 in 1994. This increase results primarily from increased
borrowing from stockholders during 1995 of approximately $4,315,500.

Depreciation and Amortization

         Depreciation and amortization expense increased by $382,880, or 54.1%,
to $1,090,594 in 1995 from $707,714 in 1994. The increase in depreciation and
amortization expense is principally a result of Hallmark's additions to property
and equipment which aggregated approximately $1,549,000 in 1995 (including
additions to equipment classified as held under capital leases).

Income Taxes

         Since Hallmark's adoption of Statement of Financial Accounting
Standards No. 109, "Accounting for Income Taxes" as of January 1, 1994 (such
standard was adopted concurrent with the Company's effective date of revocation
of its S Corporation status), a valuation allowance was provided for the total
amount of deferred tax assets.

Inflation

         Inflation has not had and is not expected to have a material impact on
Hallmark's business.

LIQUIDITY AND CAPITAL RESOURCES

         Hallmark is engaged in the research and late-stage development of
generic drugs and drug delivery technologies the funding for which, since
Hallmark's inception, has been obtained from sales of common stock to
shareholders in a series of private placements, loans from shareholders and bank
debt guaranteed by Hallmark's shareholders. During 1995 Hallmark received its
first approval to market Captopril but intense competition in the market for
this product has severely impacted expected profit margins. Accordingly,
Hallmark will continue to require equity and/or debt financing to carry out its
business plan. Currently, Hallmark is being funded substantially by advances
from Duramed as well as occasional shareholder loans. Absent such funding, there
is substantial doubt about whether Hallmark could continue as a going concern.

         At March 31, 1996 and December 31, 1995, shareholder loans aggregated
approximately $6,051,000 and $5,946,000, respectively, and obligations under
capital leases aggregated approximately $734,000 and $800,000, respectively.
Bank debt at March 31, 1996 and December 31, 1995 aggregated approximately
$1,256,000 and $1,279,000, respectively. Hallmark was indebted to Duramed at
March 31, 1996 and December 31, 1995 in connection with short term advances of
$2,010,000 and $900,000, respectively.

         Also, at March 31, 1996 and December 31, 1995, Hallmark had a working
capital deficiency of approximately $5,309,000 and $3,135,000, respectively.

         See "SUMMARY-MARKET INFORMATION" and "INDEX TO FINANCIAL STATEMENTS"
for additional information with respect to Hallmark.


                         SECURITY OWNERSHIP OF HALLMARK
   

         Hallmark common stock is owned beneficially by 53 stockholders. As of
July 15, 1996, the record date for the Special Meeting, there were 6,156,240
shares of common stock outstanding. Officers and directors of Hallmark own
beneficially approximately 63% of the outstanding shares of common stock. Each
share of common stock is entitled to one vote. Under New Jersey law and
Hallmark's governing instruments, approval by a majority of the outstanding
shares of common stock is necessary in order to effect the sale of assets.
However, the board of directors of each of Hallmark and Duramed voted has
determined, and the Asset Purchase Agreement provides, that the Transaction will
not proceed unless a majority of the shares voted by persons unaffiliated with
Duramed approve the Transaction.

                             PRINCIPAL STOCKHOLDERS
   

         The following table sets forth certain information regarding beneficial
ownership of the Company's Common Stock as of July 15, 1996, of each person
known by Hallmark to be beneficial owners of more than 5% of the outstanding
Common Stock, each of the directors of the Company, and all Directors and
executive officers of the Company as a group. Under the rules of the Securities
and Exchange Commission (the "Commission"), a person is deemed a "beneficial
owner" of a security if such person has or shares the power to vote or direct
the voting of such security or the power to dispose or direct the disposition of
such security. A person is also deemed to be a beneficial owner of any
securities of which that person has the right to acquire beneficial ownership
within 60 days. More than one person may be deemed to be a beneficial owner of
the same securities.

                         PRO FORMA FINANCIAL INFORMATION

         The following unaudited pro forma financial statements give effect to
the proposed Transaction based on the assumptions described in the accompanying
notes. These pro forma financial statements have been prepared from the
historical consolidated financial statements of Duramed and Hallmark and should
be read in conjunction therewith. The historical financial statements of Duramed
and Hallmark are incorporated by reference or appear elsewhere in this Proxy
Statement/Prospectus. See "INCORPORATION OF CERTAIN DOCUMENTS BY REFERENCE" and
"INDEX TO HALLMARK FINANCIAL STATEMENTS."

         In exchange for substantially all the assets of Hallmark, Duramed has
agreed to issue 640,000 shares of common stock and warrants to purchase 400,000
shares of common stock at $25 per share ("securities"), and agreed to assume
certain liabilities valued at $2.8 million as of March 31, 1996. In anticipation
of completing the acquisition and in exchange for the exclusive North American
marketing rights to Hallmark's Captopril product, Duramed advanced Hallmark $2.0
million through March 31, 1996, and has agreed to continue funding the operating
expenses of Hallmark commencing April 1, 1996 until the close of the
Transaction. These expenses are forecasted to approximate $314,000 per month
plus certain bio-study costs. If the Transaction is consummated, Duramed will
release Hallmark from the obligation to repay these advances.

         The excess of the value of Duramed's consideration ($16.3 million) over
the fair value of Hallmark's tangible assets acquired ($5.8 million) of $10.5
million represents a non-recurring charge for purchased research and
development. Given that this charge is non-recurring, pursuant to the
presentation requirements for pro forma financial information it has not been
included in the pro forma condensed consolidated financial statements.

         The pro forma condensed consolidated balance sheet at March 31, 1996
reflects the acquisition of Hallmark as if it had been completed on March 31,
1996. The pro forma condensed consolidated statement of operations for the three
months ended

March 31, 1996 and the year ended December 31, 1995 reflects the acquisition as
if it had been completed as of January 1, 1995.

         The pro forma financial information does not purport to be indicative
of the results that would actually have been reported if the Transaction had
occurred on such dates or which may be reported in the future. The pro forma
financial information should be read in conjunction with the historical
financial statements of Duramed and Hallmark and the related notes to such
financial statements.

                    DESCRIPTION OF DURAMED STOCK AND WARRANTS

    The terms and conditions of Duramed's capital stock are governed by the laws
of the State of Delaware as well as by Duramed's Restated Certificate of
Incorporation, as amended ("Duramed's Articles") and By-Laws, as amended
("Duramed's By-Laws").

COMMON STOCK
   

    Duramed has 50,000,000 authorized shares of Common Stock, par value $.01 per
share, of which 10,687,821 shares were issued and outstanding as of July 15,
1996. An additional 7,062,878 shares have been reserved for future issuance.
Holders of Duramed Common Stock are entitled to one vote for each share held of
record on all matters submitted to a vote of shareholders. Shareholders do not
have cumulative voting rights.
    

    Subject to preferences which may be granted to holders of Preferred Stock,
holders of Duramed Common Stock are entitled to share in such dividends as the
Board of Directors, in its discretion, may validly declare from funds legally
available. In the event of liquidation, each outstanding share of Duramed Common
Stock entitles its holder to participate ratably in the assets remaining after
payment of liabilities and liquidation preferences of any Preferred Stock which
may be outstanding.

    Except as described below, shareholders have no preemptive or other rights
to subscribe for or purchase additional shares of any class of stock or of any
other securities of Duramed, and there are no redemption or sinking fund
provisions with regard to the Duramed Common Stock. All outstanding shares of
Duramed Common Stock are fully paid and validly issued and non-assessable.

    The consent of the holders of 66 2/3% of all outstanding shares of Duramed
Common Stock is required to amend the Certificate of Incorporation. A vote of
50% of all outstanding shares is required to approve mergers, sales of assets
and similar transactions, except that this percentage increases to 66 2/3% if 
the acquiring party has purchased a 15% or greater ownership of Duramed prior to
approval of the transaction by the Board of Directors.

    Each share of Duramed Common Stock outstanding (and each share issued prior
to the occurrence of certain events) carries with it one Preferred Stock
Purchase Right to purchase, at a price of $80.00, one one-hundredth of a share
of Series A Preferred Stock. The Preferred Stock Purchase Rights are exercisable
only if a person or group acquires or obtains the right to acquire ownership of
20% or more of the Duramed Common Stock, commences a tender or exchange offer
for 30% or more of the Duramed Common Stock, or is declared an "Adverse Person"
by Duramed's Board of 


                                     - 43 -
<PAGE>   55

Directors. Duramed is entitled to redeem the Preferred Stock Purchase Rights at
a price of one-tenth of one cent per Preferred Stock Purchase Right at any time
before the twentieth day following the date a 20% position has been acquired.

    If Duramed is acquired in a merger or other business combination
transaction, each Preferred Stock Purchase Right entitles its holder to
purchase, at the Preferred Stock Purchase Right's then-current exercise price, a
number of the acquiring company's common shares having a market value at that
time of twice the Preferred Stock Purchase Rights' exercise price. The Preferred
Stock Purchase Rights also provide a similar right for holders (other than an
Acquiring Person or Adverse Person as defined in the Preferred Stock Purchase
Rights Agreement) to purchase Duramed Common Stock having a market value at that
time of twice the Preferred Stock Purchase Right's exercise price under certain
circumstances where a person or group has acquired a 30% block of the Duramed
Common Stock or been declared an "Adverse Person" by a majority of Duramed's
outside directors.

    The Provident Bank, Cincinnati, Ohio acts as Registrar and Transfer Agent of
Duramed's Common Stock.

PREFERRED STOCK

    Duramed has 500,000 authorized shares of Preferred Stock, $.001 par value
per share. In connection with the Preferred Stock Purchase Rights described
above, the Board of Directors of Duramed has provided for the issuance of
100,000 shares of a series of Preferred Stock designated as Series A Preferred
Stock
   

    On July 8, 1993, as part of an agreement with its bank, Duramed issued
74,659 shares of Series B Convertible Preferred Stock. The Series B Convertible
Preferred Stock is non-voting and is convertible at any time into 746,590 shares
of Duramed Common Stock. As of July 15, 1996, the bank had converted 68,600
shares of Series B Convertible Preferred Stock into 686,000 shares of Duramed
Common Stock.
    

    On November 6, 1995, Duramed's Board of Directors authorized the issuance of
up to 250,000 shares of 8% Cumulative Convertible Preferred Stock, Series C (the
"Series C Preferred Stock"), having a stated value of $100 per share. In
November 1995, Duramed issued $12.0 million (120,000 shares) of Series C
Preferred Stock. An additional $12.0 million (120,000 shares) of Series C
Preferred Stock was issued in February 1996. Each share of Series C Preferred
Stock is convertible at the option of the holder, with respect to its stated
value of $100, into shares of Duramed Common Stock at a price which is 15% below
the average closing price of the Duramed Common Stock over the 10-day trading
period ending two days prior to the date of conversion (the "conversion price").
The conversion price may not be less than $7.50 or more than $20.00. Any shares
of Series C Preferred 


                                     - 44-
<PAGE>   56
   
Stock remaining outstanding on November 14, 1997 will automatically be converted
into shares of Duramed Common Stock on such date. The Series C Preferred Stock
pays a dividend of 8% annually, payable quarterly in arrears, on all unconverted
shares. Through July 15, 1996, 232,500 shares of the Series C Preferred Stock
had been converted into 1,609,732 shares of the Duramed Common Stock at an
average conversion price of $14.44 per share of Duramed Common Stock.
    

   
    On August 7, 1996, Duramed completed the issuance of 200,000 shares of 
Series D Convertible Preferred Stock. See "RECENT EVENTS."
    

    The remaining shares of authorized preferred stock may be issued in one or
more series having such designated preferences, rights, qualifications and
limitations as the Board of Directors may from time to time determine without
requiring any vote of Duramed shareholders. A series of preferred stock could be
given voting, conversion, redemption, liquidation and dividend rights which, if
issued, could adversely affect the voting power and dilute the equity of the
holders of Duramed Common Stock and could have preference to Duramed Common
Stock with respect to dividend and liquidation rights. In addition, the issuance
of preferred stock by the Board of Directors could be utilized, under certain
circumstances, as a method of preventing a takeover of Duramed.

WARRANTS

    The Warrants will be issued in registered form to or at the direction of
Hallmark as provided in the Asset Purchase Agreement. The following general
summary is qualified in its entirety by reference to the form of Warrant.

    Each Warrant will entitle the registered holder to purchase one share of
Duramed Common Stock, subject to adjustment as described below. The Warrants
will be exercisable from the first anniversary of the Closing until the fifth
anniversary of the Closing (the "Termination Date") at an exercise price of
$25.00 per share. The Warrants may not be exercised for more than one-third of
the Duramed Common Stock subject thereto prior to the second anniversary of the
Closing or more than two-thirds of the Duramed Common Stock subject thereto
prior to the third anniversary of the Closing.

    Warrant certificates may be exchanged for new certificates of different
denominations, and may be exercised, by presenting them at the offices of
Duramed, 7155 East Kemper Road, Cincinnati, Ohio 45249. The purchase price for
shares of Duramed Common Stock purchased pursuant to the Warrants will be
payable in full by check to Duramed or the holder may direct that a portion of
such Common Stock to be issued upon exercise of the Warrant be withheld by
Duramed as payment, to the extent permitted by law.



                                     - 45 -
<PAGE>   57


    The exercise price of the Warrants and the number of shares issuable upon
exercise are subject to adjustments in certain events.

    No fractional shares will be issued upon the exercise of the Warrants, but
Duramed will pay the cash value of any fractional shares otherwise issuable. No
adjustments for cash dividends will be made upon any exercise of Warrants.
Holders of Warrants, as such, do not have any voting or pre-emptive rights or
any other rights as shareholders of Duramed.

                   COMPARATIVE RIGHTS OF DURAMED STOCKHOLDERS
                            AND HALLMARK SHAREHOLDERS

    If the Transaction is consummated, holders of Hallmark Common Stock will
become holders of Duramed Common Stock, which will result in their rights as
shareholders being governed by the laws of the State of Delaware, Duramed's
Articles and Duramed's By-Laws. The rights of holders of Hallmark Common Stock
currently are governed by the laws of the State of New Jersey and the
Certificate of Incorporation, as amended, of Hallmark ("Hallmark's Articles")
and the By-Laws, as amended, of Hallmark ("Hallmark's By-Laws").

    It is not practical to describe all of the differences between the laws of
the State of Delaware and the laws of the State of New Jersey, between Duramed's
Articles and Hallmark's Articles and between Duramed's By-Laws and Hallmark's
By-Laws. The following is a summary of certain differences between the rights of
a holder of Duramed Common Stock and the rights of a holder of Hallmark Common
Stock. The summary is qualified in its entirety by reference to Duramed's
Articles and Duramed's By-Laws, copies of which are filed as exhibits to the
Registration Statement of which this Proxy Statement/Prospectus is a part,
Hallmark's Articles and Hallmark's By-Laws, attached as Appendix D hereto, and
the laws of the State of Delaware and the State of New Jersey.

APPRAISAL RIGHTS

    Delaware law provides appraisal rights in the case of a stockholder
objecting to certain mergers or consolidations, but such appraisal rights do not
apply (i) to stockholders of the surviving corporation in a merger if
stockholder approval of the merger is not required or (ii) to any class of stock
which is either listed on a national securities exchange or held of record by
more than 2,000 holders unless stockholders are required to accept for their
shares in the merger or consolidation anything other than common stock of the
surviving or resulting corporation or common stock of another corporation that
is so listed or held (and cash in lieu of fractional shares).

                                     - 46 -
<PAGE>   58

    New Jersey law provides appraisal rights in the case of a shareholder 
objecting to certain mergers or consolidations, but such appraisal rights do not
apply (i) to shareholders of a surviving corporation in a merger if shareholder
approval of the merger is not required; (ii) to any class of stock which is
listed on a national securities exchange or held of record by not less than
1,000 holders unless shareholders are required to accept for their shares
anything other than cash, securities which will be so listed or traded, or such
securities and cash.

    New Jersey law further provides appraisal rights in the case of a
shareholder objecting to certain sales or other dispositions of all or
substantially all of the assets of a corporation not in the ordinary course of
business, other than transfers of assets by a corporate parent to a corporate
subsidiary, but such appraisal rights do not apply (i) to a series of stock
listed on a national securities exchange or held of record by no less than 1,000
holders; (ii) a transaction pursuant to a plan of dissolution of the corporation
which provides for distribution of substantially all of its net assets to
shareholders within one year of the transaction, and such transaction is wholly
for cash, securities which will be so listed or traded, or cash and such
securities; or (iii) a sale pursuant to an order of a court having jurisdiction.

TRANSACTIONS WITH AFFILIATES

    The Delaware Business Combinations Statute mandates a delay in certain
fundamental corporate transactions with a person owning more than 15% of the
outstanding voting shares of a corporation (an "interested stockholder") for
three years after the date such person became an interested stockholder unless:
(i) prior to such date, the Board of Directors approved either the business
combination or the transaction which resulted in the stockholder becoming an
interested stockholder; (ii) upon consummation of the transaction which resulted
in the stockholder becoming an interested stockholder, the interested
stockholder owned at least 85% of the outstanding voting stock; (iii) the
business combination is approved by the Board of Directors and by the
stockholders by a vote of two-thirds of the outstanding voting stock (excluding
shares held or controlled by the interested stockholder); or (iv) the
corporation's original certificate of incorporation provided that this Statute
would not be applicable to the corporation.

    The New Jersey Shareholders Protection Act mandates a delay in certain
fundamental corporate transactions with a person owning, directly or indirectly,
more than 10% of the voting power of the outstanding voting stock of a
corporation (an "interested shareholder") for five years after the date such
person became an interested shareholder (the "stock acquisition date"), unless
(i) the Board of Directors approved the transaction prior to the stock
acquisition date; (ii) the transaction is approved by the

                                     - 47 -

<PAGE>   59

vote of the holders of two-thirds of the voting stock not beneficially owned by
the interested shareholder; (iii) the transaction meets certain conditions
specified by the Act; (iv) the corporation did not have a class of voting stock
registered or traded on a national securities exchange or registered with the
Commission pursuant to Section 12(g) of the Securities Act of 1934 on the stock
acquisition date; (v) the interested shareholder was an interested shareholder
prior to August 5, 1986 and has not since such date increased his proportion of
the voting power of the corporation; (vi) the interested shareholder became an
interested shareholder inadvertently, as soon as practicable divests himself of
a sufficient amount of stock so that he is no longer an interested shareholder,
and would not, during the five-year period preceding the transaction, have been
an interested shareholder but for such inadvertent acquisition; (vii) the
interested shareholder became the beneficial owner of more than 50% of the
voting power of the outstanding voting stock of the corporation prior to August
5, 1986 through a purchase of stock directly from the corporation in a
transaction approved by the directors of the corporation, none of whom were then
affiliated with the interested shareholder; or (viii) the interested shareholder
became an interested shareholder on or after August 5, 1986 and before January
1, 1987.

DIVIDENDS

    Under Delaware law, a corporation may generally pay dividends out of
surplus. In addition, a corporation, under certain circumstances, may pay
dividends, if there is no surplus, out of its net profits for the fiscal year in
which the dividend is declared and/or the preceding fiscal year.

    Under New Jersey law, a corporation may not make a distribution, including
the payment of dividends, if, after such distribution, the corporation would be
unable to pay its debts as they become due in the ordinary course of business,
or the corporation's total assets would be less than its total liabilities.

LIABILITY OF DIRECTORS

    Under Delaware law and Duramed's Articles, no director may be personally
liable to the corporation or its stockholders for monetary damages for any
breach of fiduciary duty by a director, except that a director may be liable to
the extent provided by applicable law (i) for any breach of the director's duty
of loyalty to the corporation or its stockholders, (ii) for acts or omissions
not in good faith or which involve intentional misconduct or a knowing violation
of law, (iii) for unlawful dividends or other distributions or (iv) for any
transaction from which such director derived an improper personal benefit.

                                     - 48 -
<PAGE>   60

    New Jersey law provides that a corporation may, in its certificate of
incorporation, limit the directors' liability to the corporation or its
shareholders, but Hallmark has no such limitation in its certificate of
incorporation. Under New Jersey law, a corporation may not relieve its directors
from liability for any breach of duty based upon an act or omission (a) in
breach of such person's duty of loyalty to the corporation or its shareholders,
(b) not in good faith or involving a knowing violation of law or (c) resulting
in receipt by such person of an improper personal benefit. Further, directors
who vote for or concur in any of the following corporate actions are jointly and
severally liable to the corporation for damages: (i) declaration of any dividend
or distribution contrary to law; (ii) purchase of shares of the corporation
contrary to law; (iii) distribution of assets of the corporation during or after
dissolution without adequately providing for all known debts of the corporation;
(iv) liquidation of the corporation without providing for the dissolution of the
corporation and payment of all expenses incident thereto; or (v) the making of
any loan to an officer, director or employee of the corporation contrary to law.

    New Jersey law specifically provides that, in discharging their duties,
directors may rely on opinions of counsel to the corporation and upon written
reports of accountants, representations of officers of the corporation or
written reports of committees of the board.

INDEMNIFICATION

    Under both New Jersey and Delaware law, a corporation's directors and
officers as well as other employees and individuals may be indemnified against
expenses (including attorneys' fees), judgments, fines and amounts paid in
settlement in connection with specified actions, suits or proceedings, whether
civil, criminal, administrative or investigative (other than a derivative
action), if they acted in good faith and in a manner they reasonably believed to
be in or not opposed to the best interests of the corporation and, with respect
to any criminal action or proceeding, had no reasonable cause to believe their
conduct was unlawful. A similar standard of care is applicable in the case of
derivative actions, except that indemnification only extends to expenses
(including attorneys' fees) incurred in connection with the defense or
settlement of such an action and approval of a court must be obtained before
there can be any indemnification of expenses where the person seeking
indemnification has been found liable to the corporation.

Selling Shareholders or their pledgees or donees. Such sales may be made in the
over-the-counter market or in negotiated transactions, at prices and on terms
then prevailing or at prices related to the then current market price or at
negotiated prices. The Duramed Securities may be sold by means of (a) purchases
by a broker or dealer as principal and resale by such broker or dealer for its

brokerage transactions and transactions in which the broker solicits purchasers.
In effecting sales, brokers or dealers engaged by Selling Shareholders may
arrange for other brokers or dealers to participate. Brokers or dealers will
receive commissions or discounts from Selling Shareholders in amounts to be
negotiated immediately prior to the sale which amounts will not be greater than
that normally paid in connection with ordinary trading transactions.

connection with the Transaction is being passed upon for Duramed by Taft,
Stettinius & Hollister, Cincinnati, Ohio. Timothy E. Hoberg, a partner of that
firm, is Assistant Secretary of Duramed. Partners and associates of Taft,
Stettinius & Hollister beneficially own approximately 50,000 shares of Duramed

INDEPENDENT AUDITORS' REPORT
- ----------------------------

To the Board of Directors of Hallmark Pharmaceuticals, Inc.:

We have audited the accompanying balance sheets of Hallmark Pharmaceuticals,
Inc. (the "Company"), a development stage enterprise, as of December 31, 1995
and 1994 and the related statements of operations, stockholders' deficiency and
of cash flows for the years then ended and for the cumulative period from
inception (February 5, 1992) to December 31, 1995. These financial statements
are the responsibility of the Company's management. Our responsibility is to
express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such financial statements present fairly, in all material
respects, the financial position of the Company at December 31, 1995 and 1994
and the results of its operations and its cash flows for the years then ended
and for the cumulative period from inception (February 5, 1992 ) through
December 31, 1995 in conformity with generally accepted accounting principles.

The accompanying financial statements have been prepared assuming that the
Company will continue as a going concern. As discussed in Note 2 to the
financial statements, under existing circumstances, there is substantial doubt
as to the Company's ability to continue as a going concern at December 31, 1995.
The financial statements do not include any adjustments that might result from
the outcome of this uncertainty. The Company is in the development stage and,
accordingly, the ability to continue its research and development activities and
to potentially achieve profitable operations is dependent upon obtaining
adequate financing. Management's plans in regard to these matters are also
described in Note 2.

EICHEN & DIMEGLIO
February 19, 1996, except for the last paragraph of Note 11, as to which the
date is April 11, 1996.

HALLMARK PHARMACEUTICALS, INC.
(A DEVELOPMENT STAGE ENTERPRISE)
- --------------------------------

NOTES TO FINANCIAL STATEMENTS
- -----------------------------

1.  ORGANIZATION AND DESCRIPTION OF BUSINESS

Hallmark Pharmaceuticals, Inc. ("Hallmark" or the "Company") was incorporated in
New Jersey on February 5, 1992. Presently, the Company is in the process of
research and late-stage development of certain generic drugs and drug delivery
technologies.

During 1995, the Company received its first approval to market Captopril, the
generic equivalent of the brand name product Capoten, for which the brand
company's patent exclusivity expires during February 1996 (see Note 2).

The accompanying financial statements are those of a development stage
enterprise. As a development stage enterprise, the Company is currently
dependent upon debt and equity financing to continue its operations (see Note
2).

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

GOING CONCERN- The accompanying financial statements have been prepared on a
going concern basis which contemplates the realization of assets and the
satisfaction of liabilities in the normal course of business. As of December 31,
1995, the Company has a working capital deficit of approximately $3,135,000 and
an accumulated deficit since organization of approximately $12,398,000. The
Company's ability to continue its research and development activities and to
potentially achieve profitable operations is dependent upon obtaining adequate
financing. These factors, among others, raise substantial doubt as to the
Company's ability to continue as a going concern at December 31, 1995. These
financial statements do not include any adjustments which might result from the
outcome of this uncertainty.

Management of the Company has been actively seeking a strategic corporate
partner and is currently engaged in negotiations with Duramed Pharmaceuticals,
Inc. ("Duramed") to acquire the Company (see Note 11); however, there can be no
assurance that such transaction will be consummated. During 1995, Duramed
advanced the Company an aggregate of $900,000 for working capital purposes
(see Note 11). Such advances bear interest at one percent above the prime rate
per annum and are due on demand. In connection with such advances, the Company
entered into an agreement in October 1995 with Duramed granting them exclusive
marketing and distribution rights in North America to Captopril for a period of
ten years. Under such agreement, the Company will supply Captopril to Duramed at
a price equal to 110 percent of cost, as defined in the agreement. Duramed will
have sole discretion over establishing the price at which it sells the product
to customers 


                                      F-7
<PAGE>   71

and shall receive a marketing and distribution allowance equal to 8.5 percent of
net sales. Net profits, as defined, shall first be paid to Duramed for repayment
of outstanding advances. Thereafter, net profits shall be divided equally
between the Company and Duramed.

RECLASSIFICATIONS - Certain amounts in the 1994 financial statements have been
reclassified to conform to the 1995 presentation. Such reclassification
consisted primarily of $308,631 reclassified from "Other assets - net" to
"Deposits on equipment".

RESEARCH AND DEVELOPMENT - Research and development costs, including related raw
materials and supplies, are expensed as incurred.

DEPRECIATION AND AMORTIZATION - Depreciation of property and equipment and
amortization of assets held under capital leases is computed on the
straight-line method over an estimated useful life of the related assets of 5
years.

INVENTORIES - Inventories are stated at the lower of cost, determined on the
first-in, first-out basis, or market.

DEFERRED FINANCING COSTS - Deferred financing costs at December 31, 1995 consist
of professional fees incurred in connection with the Company's efforts to raise
additional funds.

ORGANIZATION COSTS - Organization costs are being amortized over a period of 5
years. The net book value of such costs was approximately $6,200 and $12,300 at
December 31, 1995 and 1994, respectively, and is included in the balance sheet
caption "Other assets -net".

DEFERRED LOAN COSTS - Deferred loan costs are being amortized over a period of 5
years. The net book value of such costs was approximately $25,700 and $13,500 at
December 31, 1995 and 1994, respectively, and is included in the balance sheet
caption "Other assets - net".

INCOME TAXES - As of January 1, 1994, the Company elected to be taxed as a C
Corporation for Federal income tax purposes and computes its tax provisions
under Statement of Financial Accounting Standards ("SFAS") No. 109, "Accounting
for Income Taxes". Under SFAS No. 109, income taxes are recognized using a
liability approach and deferred tax assets and liabilities are computed for
temporary differences using current income tax rates. The adoption of SFAS No.
109 had no effect on the accompanying financial statements.

Prior to January 1, 1994 the Company had elected to be treated as an S
Corporation for Federal income tax purposes and accordingly, income or loss
passed through to the stockholders' individual 


                                      F-8
<PAGE>   72

income tax return and no Federal income tax was imposed on the Company. For New
Jersey income tax purposes, the Company was taxed as a regular C Corporation
since inception since New Jersey did not recognize S Corporation status prior to
1994.

STOCK OPTIONS - Statement of Financial Accounting Standards No. 123, "Accounting
for Stock-Based Compensation", requires the Company either to adopt the fair
value method of accounting for stock options in its financial statements or to
retain its existing method and disclose the pro forma effects of using the fair
value method beginning in 1996. The Company intends to retain its existing
method of accounting for stock options and to include pro forma disclosures in
the notes to the financial statements. Accordingly, the standard will have no
effect on the Company's financial condition or results of operations.

USE OF ESTIMATES - The preparation of the financial statements in conformity
with generally accepted accounting principles require management to make
estimates and assumptions that affect the amounts reported in the financial
statements and accompanying notes. Actual results could differ from those
estimates.

NET LOSS PER SHARE - Net loss per share was computed based on the weighted
average number of common shares outstanding during the respective periods and
does not include the assumed exercise of stock options, since such effect would
be anti-dilutive.

7.  CAPITAL LEASE OBLIGATIONS AND DUE TO AFFILIATE

The Company leases equipment from Hallmark Leasing Associates ("Hallmark
Leasing"), a partnership in which the partners are also stockholders of the
Company. These leases, which represent the majority of Hallmark's capital lease
obligations, expire during 1997, 1998 and 1999 and are accounted for as capital
leases as a result of certain provisions in the lease agreements. In addition,
the Company borrowed $100,000 in October 1995 from Hallmark Leasing. Such amount
bears interest at 10 percent per annum, is due in 1996, and is classified as
"Due to affiliate" on the balance sheet.

The Company also leases computer equipment under a capital lease agreement with
an unrelated entity.

Future minimum lease payments, by year and in the aggregate, and the present
value of the future minimum lease payments at December 31, 1995 are as follows:

At December 31, 1995 and 1994, the net book value of equipment held under
capital leases aggregated $566,920 and $618,154, respectively. Also, accrued
interest related to such capital lease obligations at December 31, 1995 and 1994
aggregated $17,054 and $18,753, respectively, and is included in the balance
sheet caption "Interest payable to related parties".

8.  COMMON STOCK

During 1995, the Company sold an aggregate of 105,600 shares of its common stock
to new and existing stockholders for $528,000.

During 1994, the Company sold an aggregate of 50,000, 456,250 and 414,390 shares
of its common stock to new and existing stockholders for $50,000, $1,368,750 and
$2,071,950, respectively.

The shareholders' agreement contains provisions which limit the transfer of the
Company's common stock and grant the stockholders certain "first refusal",
"piggyback" and "demand" registration rights.

In connection with the above transactions, the Company issued an additional
30,000 and 50,000 shares during 1995 and 1994, respectively, to certain
management members in consideration for services rendered. Accordingly, the
Company recorded a charge to operations and a credit to common stock for the
fair market value of the shares at the time of issuance. Such amounts aggregated
$83,400 and $150,000 during 1995 and 1994, respectively.

During 1995, the Company issued options to certain of its stockholders to
purchase a total of 620,100 shares of the Company's common stock in connection
with their loans aggregating $3,100,500 (see Note 6). The options entitle the
holder to purchase shares at $5 per share and are exercisable for a two year
period from the date of grant.

In June 1994, the Company issued options to all stockholders of record as of May
6, 1994 to purchase a total of 1,500,000 shares of the Company's common stock in
connection with their personal guarantee of bank indebtedness as described in
Note 4. The 


                                      F-12
<PAGE>   76

options entitle the holder to purchase shares at $1 per share and are
exercisable for a two year period commencing 18 months from the date of grant.
Each optionee received options to purchase shares of the Company's common stock
in proportion to their ownership interest immediately prior to the grant of such
options. Accordingly, upon exercise of all of the options, each stockholders'
ownership interest would remain unchanged relative to each other. In connection
with this transaction, the Company has recorded a charge to operations for
$250,000, which, in management's opinion, represents the estimated value of the
consideration received in exchange for their personal guarantees. Such amount is
included in the expense caption "General and administrative" in the statement of
operations.

During January 1994, the Company increased the number of shares authorized for
issuance from 5,000,000 to 10,000,000.

9.  INCOME TAXES

At December 31,1995, the Company has a Federal tax loss carryforward of
approximately $8,000,000 expiring during 2009 and 2010. Also, at such date, the
Company has a New Jersey tax loss carryforward of approximately $11,100,000,
expiring between 1999 and 2002. The difference between the accumulated deficit
of $12,398,477 and the state tax loss carryforward of $11,100,000 at December
31,1995 relates principally to the capitalization of start-up expenses for
income tax purposes, the loan guarantee fee described in Note 8, premiums on
officers' life insurance, employee benefits, and depreciation and amortization.
The New Jersey and Federal income tax loss carryforwards differ since the
Company was taxed as an S Corporation for Federal income tax purposes prior to
January 1, 1994.

In accordance with SFAS No. 109, the Company has computed the components of
deferred income taxes at December 31, 1995 and 1994 as follows:

</TABLE>

At December 31, 1995 and 1994 a valuation allowance of $3,729,000 and
$1,700,000, respectively, has been provided since the realization of the
deferred tax benefits are not more likely than not. The Company's deferred tax
benefits were generated principally as a result of such losses.

Rent expense for the years ended December 31, 1995 and 1994 aggregated
approximately $124,200 and $102,600, respectively.

During 1995, the Company was granted an option, exercisable on June 1, 1998, to
purchase its facility for a minimum of $2,088,955, subject to increases for the
percentage change in the Consumer Price Index ("CPI") from June 1, 1995 (the
"Base CPI") through the month of closing, up to a maximum of $2,340,000. Also,
the Company was granted a second option (the "Second Option"), exercisable on
June 1, 2000 to purchase such facility for $2,088,955 subject to increases for
the percentage change in the Base CPI through the month of closing. The Second
Option contains no maximum purchase price.

EMPLOYMENT AGREEMENTS - The Company is obligated under several employment
agreements, expiring in March 1997 through November 1999. Minimum annual

In addition, certain of such employment agreements provided that the individuals
receive shares of the Company's common stock as consideration for services
rendered (see Note 8).


CONTINGENT FINANCING FEES - In February 1995, the Company entered into an
agreement with an entity to assist the Company in raising additional expansion
capital for professional fees ranging from a minimum of $75,000 (increased to
$350,000 under certain circumstances), to a maximum of $1,000,000, depending
upon the 


                                      F-14
<PAGE>   78

amount of the financing. Such agreement was terminated by the Company during
August 1995 and all invoiced professional fees from this entity (aggregating
approximately $112,000) were paid by the Company. Subsequent to the termination
of this agreement, the Company received notice from this entity claiming
additional professional fees would be due if a transaction with Duramed were
consummated. Legal counsel is currently investigating the nature of this
potential claim and at present, cannot assess the likelihood of the Company's
liability should a claim be filed. The financial statements do not include any
liability relating to this matter.

In October 1995, the Company entered into an agreement with an entity to assist
the Company in evaluating and negotiating potential financing offers. A final
fee of $50,000 would be due to this entity upon the closing of such a
transaction. No provision has been made for such fee as of December 31, 1995.

11.  SUBSEQUENT EVENTS

From January 1, 1996 through February 19, 1996, Duramed loaned the Company an
additional $800,000 on the same terms as the earlier demand loans (see Note 2).

Also, during January 1996, the Company entered into a marketing and distribution
agreement with Duramed on substantially the same terms as the Captopril
agreement (see Note 2) for an additional drug product currently under
development by the Company.

During January and February 1996, the Company adopted certain measures to
conserve cash flow, including the suspension of interest and principal payments
on certain amounts due to stockholders and on capital lease obligations to
Hallmark Leasing.

On April 11, 1996, the Company entered into a definitive agreement with Duramed
providing for the acquisition of assets and assumption of certain liabilities of
the Company. Under the terms of such agreement, the Company would receive
640,000 shares of Duramed common stock and warrants to purchase 400,000 shares
of Duramed common stock at a purchase price of $25 per share. Consummation of
the transaction is subject to certain customary conditions, including approval
of the Company's shareholders and certain regulatory agencies and other third
parties.

INDEPENDENT AUDITORS' REPORT

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


To the Board of Directors of Hallmark Pharmaceuticals, Inc.:

We have audited the accompanying balance sheets of Hallmark Pharmaceuticals,
Inc. (the "Company"), a development stage enterprise, as of December 31, 1994
and 1993 and the related statements of operations, stockholders' deficiency and
of cash flows for the years then ended and for the cumulative period from
inception (February 5, 1992) to December 31, 1994. These financial statements
are the responsibility of the Company's management. Our responsibility is to
express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such financial statements present fairly, in all material
respects, the financial position of the Company at December 31, 1994 and 1993
and the results of its operations and its cash flows for the years then ended
and for the cumulative period from inception (February 5, 1992 ) through
December 31, 1994 in conformity with generally accepted accounting principles.

intention of the Company's stockholders to continue to provide this financial
support.

2.       SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

RESEARCH AND DEVELOPMENT - Research and development costs, including related raw
materials and supplies, are expensed as incurred.

DEPRECIATION AND AMORTIZATION - Depreciation and amortization is computed on the
straight-line method over an estimated useful life of the related assets of 5
years.

ORGANIZATION COSTS - Organization costs are being amortized over a period of 5
years. The net book value of such costs was approximately $12,300 and $18,500 at
December 31, 1994 and 1993, respectively, and is included in the balance sheet
caption "Other assets - net".

DEFERRED LOAN COSTS - Deferred loan costs are being amortized over a period of 5
years. The net book value of such costs was approximately $13,500 at December
31, 1994 and is included in the balance sheet caption "Other assets - net".

INCOME TAXES - As of January 1, 1994, the Company has elected to be taxed as a C
Corporation for Federal income tax purposes and computes its tax provisions
under Statement of Financial Accounting Standards ("SFAS") No. 109, "Accounting
for Income Taxes". Under SFAS No. 109, income taxes are recognized using a
liability approach and deferred tax assets and liabilities are computed for
temporary differences using current income tax rates. The adoption of SFAS No.
109 had no effect on the accompanying financial statements.

Prior to January 1, 1994 the Company had elected to be treated as an S
Corporation for Federal income tax purposes and accordingly, income or loss
passed through to the stockholders' individual income tax return and no Federal
income tax was imposed on the 

                                      F-22
<PAGE>   86

Company. For New Jersey income tax purposes, the Company was taxed as a regular
C Corporation since inception since New Jersey did not recognize S Corporation
status prior to 1994.

NET LOSS PER SHARE - Net loss per share was computed based on the weighted
average number of common shares outstanding during the respective periods and
does not include the assumed exercise of stock options, since such effect would
be anti-dilutive.

3.       PROPERTY AND EQUIPMENT

In connection with the personal guarantee of bank indebtedness, as described
above, the guaranteeing stockholders were issued stock options (see Note 7).

5.       DUE TO STOCKHOLDERS

Due to stockholders at December 31, 1994 and 1993 consisted of notes payable to
the stockholders of the Company. These notes mature during 1997 ($885,000), 1998
($614,997) and 1999 ($456,250) and bear interest at the rate of 6.35 percent per
annum payable annually on the anniversary date of the notes. Accrued interest
related to such notes aggregated $85,974 and $61,222 at December 31, 1994 and
1993, respectively, and is included in the balance sheet caption "Interest
payable to stockholders".

6.       CAPITAL LEASE OBLIGATIONS

7.       COMMON STOCK

During January 1994, the Company increased the number of shares authorized for
issuance from 5,000,000 to 10,000,000.

During 1994, the Company sold an aggregate of 50,000, 456,250 and 414,390 shares
of its common stock to new and existing stockholders for $50,000, $1,368,750 and
$2,071,950, respectively. In connection with these private placements, the
stockholders loaned the Company a total of $486,250 (see Note 5).

During 1993, the Company sold an aggregate of 1,025,000 and 1,500,000 shares of
its common stock to existing stockholders for $410,000 and $1,500,000,
respectively. In connection with these private placements, the stockholders
loaned the Company a total of $614,997 (see Note 5).

The shareholders' agreement contains provisions which limit the transfer of the
Company's common stock and grant the stockholders certain "first refusal",
"piggyback" and "demand" registration rights.

In connection with the above transactions, the Company issued an additional
50,000 and 631,250 shares during 1994 and 1993, respectively, to certain
management members in consideration for services rendered. Accordingly, the
Company recorded a charge to operations and a credit to common stock for the
fair market value of the shares at the time of issuance. Such amounts aggregated
$150,000 and $202,000 during 1994 and 1993, respectively.


                                      F-25
<PAGE>   89

On June 25, 1994, the Company issued options to all stockholders of record as of
May 6, 1994 to purchase a total of 1,500,000 shares of the Company's common
stock in connection with their personal guarantee of bank indebtedness as
described in Note 4. The options entitle the holder to purchase shares at $1 per
share and are exercisable for a two year period commencing 18 months from the
date of grant. Each optionee received options to purchase shares of the
Company's common stock in proportion to their ownership interest immediately
prior to the grant of such options. Accordingly, upon exercise of all of the
options, each stockholders' ownership interest would remain unchanged relative
to each other. In connection with this transaction, the Company has recorded a
charge to operations for $250,000, which, in management's opinion, represents
the estimated value of the consideration received in exchange for their personal
guarantees. Such amount is included in the expense caption "General and
administrative" in the statement of operations.

8.       INCOME TAXES

At December 31, 1994, the Company has a Federal tax loss carryforward of
approximately $3,800,000 expiring during 2009. Also, at such date, the Company
has a New Jersey tax loss carryforward of approximately $6,877,000, expiring
between 1999 and 2001. The difference between the accumulated deficit of
$7,583,070 and the state tax loss carryforward of $6,877,000 at December 31,
1994 relates principally to the capitalization of start-up expenses for income
tax purposes, the loan guarantee fee described in Note 7, premiums on officers'
life insurance and depreciation and amortization. The New Jersey and Federal
income tax loss carryforwards differ since the Company was taxed as an S
Corporation for Federal income tax purposes prior to January 1, 1994.

In accordance with SFAS No. 109, the Company has computed the components of
deferred income taxes as follows:

</TABLE>


At December 31, 1994, a valuation allowance of $1,700,000 has been provided
since the realization of the deferred tax benefits are not more likely than not.
The Company's deferred tax benefits were generated principally as a result of
such losses.

In addition, certain of such employment agreements provided that the individuals
receive shares of the Company's common stock as consideration for services
rendered (see Note 7).

LEASEHOLD IMPROVEMENTS - In connection with certain modifications to its
manufacturing facility, the Company is contractually obligated for approximately
$140,000 in additional leasehold improvements at December 31, 1994.

10.      SUBSEQUENT EVENTS

During February and March 1995, the Company sold an additional 64,400 shares of
its common stock at $5 per share to private 


                                      F-27
<PAGE>   91

investors for an aggregate of $322,000. Also, during such period, certain
stockholders loaned the Company an additional $1,200,000. In connection with
these loans, such stockholders were granted options to purchase, within a 2 year
period from the grant date, a total of 240,000 shares of the Company's common
stock at $5 per share.

During February 1995, the Company amended its lease agreement relating to its
manufacturing facility at 400 Campus Drive to include an additional 15,230
square feet of adjoining space. In connection with such amendment, the Company
was granted an option, exercisable on June 1, 1998, to purchase this facility
for a minimum of $2,088,955, subject to increases for the percentage change in
the Consumer Price Index ("CPI") from June 1, 1995 (the "Base CPI") through the
month of closing, up to a maximum of $2,340,000. Also, the Company was granted a
second option (the "Second Option"), exercisable on June 1, 2000 to purchase
such facility for $2,088,955 subject to increases for the percentage change in
the Base CPI through the month of closing. The Second Option contains no maximum
purchase price.

During February 1995, the Company entered into an agreement with an entity to

NOTES TO UNAUDITED INTERIM FINANCIAL STATEMENTS
- -----------------------------------------------

1  INTERIM FINANCIAL DATA

The accompanying unaudited financial statements have been prepared in accordance
with generally accepted accounting principles for interim financial information
and Article 10 of Regulation S-X. Accordingly, they do not include all of the
information and footnotes required by generally accepted accounting principles
for complete financial statements. In the opinion of management, such financial
statements contain all adjustments (consisting of normal recurring accruals)
considered necessary for a fair presentation. Operating results for the three
month period ended March 31, 1996 are not necessarily indicative of the results
that may be expected for the year ended December 31, 1996. For further
information, refer to the financial statements for the year ended December 31,
1995 and notes thereto included herein.

During the three month period ended March 31, 1996, net sales consisted of
sales of the Company's first product, Captopril, to Duramed Pharmaceuticals,
Inc. ("Duramed") in accordance with the terms of a distribution agreement
between the parties. As the result of such sales, the Company is no longer
considered to be in the development stage.

2.  GOING CONCERN

The accompanying financial statements have been prepared on a going concern
basis which contemplates the realization of assets and the satisfaction of
liabilities in the normal course of business. As of March 31, 1996, the Company
has a working captial deficit of approximately $5,309,000 and an accumulated
deficit since organization of approximately $13,984,000. The Company's ability
to continue its research and development activities and to potentially achieve
profitable operations is dependent upon obtaining adequate financing. These
factors, among others, raise substantial doubt as to the Company's ability to
continue as a going concern at March 31, 1996. These financial statements do
not include any adjustments which might result from the outcome of this
uncertainty.

During the quarter ended March 31, 1996, the Company received additional loans
from Duramed of approximately $1,110,000 to continue to finance its operations,
as well as $150,000 in additional stockholder loans and $50,000 from sale of
its common stock.

On April 11, 1996, the Company entered into a definitive agreement with Duramed
providing for the acquisition of assets and assumption of certain liabilities
of the Company. Under the

                                     F-33
























<PAGE>   97
terms of such agreement, the Company would receive 640,000 shares of Duramed
common stock and warrants to purchase 400,000 shares of Duramed common stock
at a purchase price of $25 per share. Consummation of the transaction is
subject to certain customary conditions, including approval of the Company's
shareholders and certain regulatory agencies and other third parties.

3.  NET LOSS PER SHARE

Net loss per share was computed based on the weighted average number of common
shares outstanding during the respective periods and does not include the
assumed exercise of stock options, since such effect would be anti-dilutive.

4.  INVENTORIES

Inventories consist of the following:

5.  CONTINGENCIES

In February 1995, the Company entered into an agreement with an entity to
assist the Company in raising additional expansion capital for professional
fees ranging from a minimum of $75,000 (increased to $350,000 under certain
circumstances), to a maximum of $1,000,000, depending upon the amount of the
financing. Such agreement was terminated by the Company during August 1995 and
all invoiced professional fees from this entity (aggregating approximately
$112,000) were paid by the Company. Subsequent to the termination of this
agreement, the Company received notice from this entity claiming additional
professional fees would be due if a transaction with Duramed were consummated.
Legal counsel is currently investigating the nature of this potential claim and
at present, cannot assess the likelihood of the Company's liability should a
claim be filed. The financial statements do not include any liability relating
to this matter.

In October 1995, the Company entered into an agreement with an entity to assist
the Company in evaluating the negotiating potential financing offers. A final
fee of $50,000 would be due to this entity upon the closing of such a
transaction. No provision has been made for such fee as of March 31, 1996.

                       PLAN OF LIQUIDATION AND DISSOLUTION

                                       OF

                         HALLMARK PHARMACEUTICALS, INC.


                  This Plan of Liquidation and Dissolution (the "Plan") is
intended to carry out the complete liquidation and dissolution of Hallmark

sale of its assets, and is as follows:
   
                  1. The shareholders of the Corporation, pursuant to action
taken at a special meeting of shareholders to be held on September 11, 1996 
shall approve the complete liquidation and dissolution of the Corporation in
accordance with the terms and provisions of this Plan and the sale of all of the
Corporation's assets to Duramed Pharmaceuticals, Inc. ("Duramed") pursuant to
the terms of the Asset Purchase Agreement dated as of April 9, 1996 (the
"Agreement").
    
                  2. Following the adoption of the Plan, the Corporation shall
transfer all of its rights in the assets of the Corporation to Duramed, in
exchange for the assumption by Duramed of certain liabilities of the Corporation
and for 640,000 shares of Duramed Common Stock and warrants to Purchase an
additional 400,000 shares of Duramed Common Stock, in accordance with and
subject to the terms and conditions of the Agreement. Pursuant to the Agreement,
64,000 of the shares and 40,000 of the warrants will be held in escrow (the
"Escrow") for a period of one year following the closing.

                  3. After the Closing, the Corporation shall pay, or shall make
adequate provision for the payment of, all known liabilities of the Corporation
not assumed by Duramed, including the payment of principal and interest due on
any loans made to the Corporation by shareholders and the payment of amounts due
to employees and creditors. To the extent practicable, the Corporation shall pay
its liabilities in Duramed shares at their fair market value as of a date
determined by agreement between the Company and its creditors. If necessary, the
Corporation may sell Duramed shares to provide funds to pay liabilities to
creditors or employees who do not agree to payment in Duramed shares. The
Corporation may also set aside such additional Duramed shares (if any) as the
directors deem necessary for payment of unascertained or contingent liabilities
of the Corporation. Thereafter, the Corporation shall distribute to its
shareholders as a liquidating distribution in complete

                                       A-1

Duramed shares, (ii) any remaining Duramed warrants, (iii) the right to receive
any distributions from the Escrow, (iv) the right to receive any distributions
of Duramed shares set aside for the payment of unascertained or contingent
liabilities, and (v) any other remaining assets of the Corporation, or the
proceeds from the disposition thereof. The distribution shall be made to the
Corporation's shareholders pro rata in accordance with the number of shares held
by each.

                  4. The Corporation shall send notice to all persons holding
options to purchase common stock of the Corporation advising the option holders
of the Plan and giving them a period of not less than 30 days from the date of
the notice in which to exercise their options and participate in the Plan as
shareholders. Options that are not exercised within 30 days of the notice will
be canceled.

                  5. Promptly after the Closing, Corporation shall cause a
Certificate of Dissolution to be prepared, executed, and filed in the Office of
the Secretary of State of New Jersey.

perform all acts, execute all documents, file all reports, statements,

name of and on behalf of the Corporation which they shall deem necessary or
desirable to complete the distribution of the assets and properties of the
Corporation to the shareholders in complete liquidation of the Corporation,
subject, however to the provisions of the Plan.

         (d)  Any obligation of the Company arising under any Company

Insurance Policy for a period of two years after the Closing, to the extent such
premiums do not exceed 125% of the current cost thereof; or

         (i)  any liability to Armata Partners arising under the Amendment 
dated March 6, 1996 to the Investment Advice and Services Engagement.

         Section 1.4                HOLDBACK; ESCROW.

         (a)  At the Closing, Duramed shall deliver to the Escrow Agent
certificates representing that number of shares of Duramed Common Stock equal to
Ten Percent (10%) of the Duramed Shares to be issued pursuant to Section 1.2

Warrants to be issued pursuant to Section 1.2 hereof (the "Escrow Warrants").
The Escrow Shares, Escrow Warrants, any dividends or distributions with respect

shall be held by the Escrow Agent pursuant to an Escrow Agreement dated as of
the Closing Date between Duramed, the Company and the Escrow Agent substantially
in the form of Exhibit 1.4(a) hereto (the "Escrow Agreement"). During the term
of the Escrow Agreement, as provided in Section 1.5 hereof, the Escrow Agent
shall pay part or all of the Escrow Fund to Duramed as indemnification for
costs, expenses (including reasonable attorneys' fees), or damages suffered by
Duramed as a result of the breach by the Company of any representation or
warranty of the Company contained herein or made as of the Closing, as more
particularly provided in Section 8.1 hereof. Any portion of the Escrow Fund
returned to Duramed in the form of Escrow Shares pursuant to a claim for
indemnification shall be determined based on the average Market Price of Duramed

which such

                                       B-8

<PAGE>   113



payment to Duramed is made. The value of any portion of the Escrow Fund returned
to Duramed in the form of Warrants pursuant to a claim for indemnification shall
be equal to the fair market value of such Warrants on the day on which such
payment to Duramed is made, as reasonably determined by a third party
experienced in valuing such securities, to be selected jointly by the Company
and Duramed.

         (b) Unless and until all or any portion of the Escrow Fund is returned
to Duramed, the Company shall be the owner for tax purposes of the Escrow Fund.
During the term of the Escrow Agreement, the Company shall have the right to
direct the Escrow Agent in writing to sell all or any portion of the Escrow
Shares or Escrow Warrants. Upon receipt of such direction, the Escrow Agent
shall promptly effect such sale by offering such shares or warrants for sale
through a duly licensed broker at the then-prevailing market price on the NASDAQ
system, and shall thereafter hold the proceeds of such sale in the Escrow Fund
until directed to pay such proceeds pursuant to Section 1.5 hereof or until the
termination of the Escrow Agreement.

         (c) The parties acknowledge that the Company may choose to liquidate
its remaining assets and terminate its corporate existence at or shortly after
the Closing and during the term of the Escrow Agreement. In such event, the
Company Representative shall represent the interests of the Company and persons
whose interests arise through or from the Company in all matters related to this
Agreement or the Escrow Agreement. Upon termination of the Company's corporate
existence, all references to the Company in Sections 1.3(h), 1.4, 1.5 and 1.6
hereof shall be deemed to refer to the Company Representative, unless another
interpretation is clearly required.

         Section 1.5         PAYMENT OF CLAIMS AGAINST ESCROW FUND.

         (a) From and after the Closing, if Duramed desires to assert a claim
for indemnification pursuant to Section 8.1 hereof, it shall deliver to the
Company a notice signed by an officer of Duramed (a "Claim Notice") (i) to the
effect that Duramed has a claim for indemnifiable damages pursuant to Section

reasonable detail the Company's grounds for disputing the relevant Claim, as
well as the Company's calculation of the amount, if any, due Duramed with
respect to such Claim. If the Company fails to respond within such 20-day period

period, no final agreement has been reached between Duramed and the Company, the
parties shall appoint an arbitrator to hear the claim under the rules of the
American Arbitration Association. The decision of the arbitrator so appointed as
to the validity of any Claim shall be conclusive and binding upon the parties to
the dispute, and the Escrow Agent shall be entitled to rely on such decision and
shall act in accordance with such decision and make payment out of the Escrow
Fund in accordance therewith. The fees and expenses of the Company and Fifty
Percent (50%) of the fees and expenses of the arbitrator shall be paid by the
Escrow Agent from the Escrow Fund. The fees and expenses of Duramed and Fifty
Percent (50%) of the fees and expenses of the arbitrator shall be paid by

Escrow Agreement) to the Company or its designees.

         (b) In making the distributions described in Section 1.6(a) hereof,

fractional share to which the Company or its designees may be entitled, but
shall pay to the Company or its designees in lieu of such fractional share the

being conducted and is duly qualified and in good standing (or has active status
if such state does not recognize the concept of good standing) as a foreign
corporation to do business in the respective jurisdictions where the character

would not in the aggregate have a material adverse effect on the Condition of
the Company.

not subject to, nor were they issued in violation of, any preemptive rights or
federal or, except as set forth in Section 3.2 of the Company Disclosure

March 31, 1996, the Company has not issued any shares of Company Common Stock or
options to purchase shares of Company Common Stock except for the issuance of

future, any shares of capital stock or any securities convertible into,
exchangeable for, or evidencing the right to subscribe for, any shares of
capital stock of the Company. Except as set forth in Section 3.2 of the Company
Disclosure Schedule, there are no voting trusts or other agreements or
understandings to which the Company is a party with respect to its voting of the

     Section 3.5 NO VIOLATION. Except as set forth in Section 3.5 of the Company
Disclosure Schedule, the execution, delivery and performance of this Agreement
and the consummation of the transactions contemplated hereby will not (i)
constitute a breach or violation of or default under the Certificate of

party to any of the above or affect the validity or effectiveness of any of the

in the aggregate, have a material adverse effect on the Condition of the Company

hereby will not constitute a breach or violation of or default under any law,

the industry in which Duramed or any of the Duramed Subsidiaries operate) or

Subsidiaries' business after the date hereof on substantially the same basis as
heretofore operated.

         Section 4.5 COMMISSION REPORTS AND FINANCIAL STATEMENTS. Duramed has
previously delivered to the Company true and complete copies of Duramed's (i)
Annual Report on Form 10-K for the year ended December 31, 1995, as filed with
the Commission on April 1, 1996; and (ii) all other reports, proxy statements
and registration statements (including Current Reports on Form 8-K) filed by it
with the Commission since January 1, 1996 (collectively, the "Duramed SEC
Filings"). As of their respective dates, the Duramed SEC Filings did not contain
any untrue statement of a material fact or omit to state any material fact
required to be stated therein or necessary to make the statements therein, in
light of the circumstances under which they were made, not misleading. The
financial statements of Duramed and the Duramed Subsidiaries included in the
Duramed SEC Filings present fairly the financial position, results of operations
and cash flows of Duramed and the Duramed Subsidiaries as at the dates or for
the periods indicated therein in conformity with GAAP.

         Section 4.6 PROXY STATEMENT/PROSPECTUS. When the Proxy
Statement/Prospectus shall first be mailed to the stockholders of the Company,
and at all times subsequent thereto up to and including the Closing, the
information with respect to Duramed and the Duramed Subsidiaries set forth in
the Proxy Statement/Prospectus will not contain any untrue statement of a
material fact or omit to state any material fact required to be stated therein
or necessary to make the statements contained therein not misleading. If, at any
time prior to the Closing, any event relating to Duramed or the Duramed
Subsidiaries shall occur which should be disclosed in the Proxy
Statement/Prospectus and which is not so disclosed, Duramed shall promptly so
inform the Company.

         Section 4.7 ABSENCE OF CERTAIN CHANGES OR EVENTS.  Except as set forth
or referred to in the Duramed SEC Filings (including the financial statements
and footnotes thereto), since December 31, 1995, each of Duramed and the Duramed
Subsidiaries has conducted its business only in the ordinary and usual course
and there has not occurred any material adverse change in the Condition of
Duramed and the Duramed Subsidiaries taken as a whole.

         Section 4.8 NO UNDISCLOSED LIABILITIES. Except as set forth or referred
to in the Duramed SEC Filings (including the financial statements and footnotes
thereto), neither Duramed nor the Duramed Subsidiaries has any liabilities or
obligations (whether absolute, accrued, contingent or otherwise) that in the

                                      B-32

<PAGE>   137



aggregate have or may reasonably be expected to have a material adverse effect
on the Condition of Duramed and the Duramed Subsidiaries taken as a whole.

         Section 4.9 TAXES AND TAX RETURNS. Duramed and each of the Duramed
Subsidiaries (collectively, the "Duramed Group") has timely filed or been
included in all tax returns, declarations, reports, estimates, information
returns, statements and other returns, the non-filing of which would have a
material adverse effect on the Condition of Duramed (collectively, the "Duramed
Returns") relating to Duramed Taxes (as defined below) required to be filed
under U.S. federal, state, local or any foreign laws (taking into account any
extensions of time for filing such Duramed Returns) with respect to all Duramed
Taxes for all years and periods (or portions thereof) for which any such Duramed
Returns were due. All such Duramed Returns were in all material respects true,
complete and correct with respect to all Duramed Taxes. Except as set forth in
Section 4.9 of the Duramed Disclosure Schedule, neither Duramed or any of the
Duramed Subsidiaries is currently the beneficiary of any extension of time
within which to file any Duramed Return. Except as set forth in Section 4.9 of
the Duramed Disclosure Schedule, the Duramed Group has paid or made provision
for (by a tax accrual or tax reserve on the most recent balance sheets of the
Duramed Group contained in the Duramed SEC Filings, which accruals or reserves
have been recorded in accordance with GAAP), all Duramed Taxes (except for such
Duramed Taxes which if not so paid or provided for would not, in the aggregate,
have a Material Adverse Effect on the Condition of Duramed and the Duramed
Subsidiaries taken as a whole) in respect of all taxable periods or portions
thereof ending on or before the date of such balance sheets. Except as set forth
in Section 4.9 of the Duramed Disclosure Schedule, (a) any Duramed Taxes
incurred or accrued since such date have arisen in the ordinary course of
business, (b) there are no material liens for Duramed Taxes upon the assets of
Duramed or any of the Duramed Subsidiaries except liens for Duramed Taxes not
yet due, (b) the Duramed Group is not delinquent in the payment of any federal
income or other Duramed Taxes and (c) there are no outstanding deficiencies,
assessments, or written proposals for assessment of federal income or other
Duramed Taxes proposed, asserted or assessed against the Duramed Group, or
agreements extending the period of assessment or collection of any Duramed
Taxes. Each of Duramed and the Duramed Subsidiaries has withheld and paid all
Duramed Taxes required to be withheld and paid in connection with amounts paid
or owing to any employee, independent contractor, creditor, stockholder or other
third party. Duramed has filed a return for federal income tax purposes on
behalf of itself and the Duramed Subsidiaries for periods up to and including
December 31, 1994 as a common parent corporation of an "affiliated group"
(within the meaning of Section 1504(a) of the Code), of which such subsidiaries
are "includable corporations" (within the meaning of Section 1504(b) of the
Code). Except as set forth in Section 4.9

                                      B-33

<PAGE>   138



of the Duramed Disclosure Schedule, the statute of limitations for the
assessment of federal income taxes has expired for all federal income tax
returns of Duramed and the Duramed Subsidiaries, and no federal income tax
return of Duramed and the Duramed Subsidiaries has been examined by the Internal
Revenue Service. Except as set forth in Section 4.9 of the Duramed Disclosure
Schedule, no federal, state, local or foreign audits or other administrative
proceedings or court proceedings which are material to the Condition of the
Duramed Group are presently pending with regard to any Duramed Taxes or Duramed
Returns. As used herein, "Duramed Taxes" mean (A) all net income, gross income,
gross receipts, sales, use, transfer, franchise, profits, withholding, payroll,
employment, excise, severance, property or windfall profits taxes, or other
taxes of any kind whatsoever, together with any interest and any penalties,
additions to tax or additional amounts imposed by any taxing authority (domestic
or foreign) upon Duramed or any of the Duramed Subsidiaries or their properties
with respect to all periods or portions thereof ending on or before the Closing
Date and/or (B) any liability of Duramed or any of the Duramed Subsidiaries for
the payment of any amounts of the type described in the immediately preceding
clause (A) as a result of being a member of an affiliated or combined group
other than the Duramed Group.

         Section 4.10 LITIGATION. Except as set forth or referred to in the
Duramed SEC Filings (including the financial statements and footnotes thereto),
there are no actions, suits, claims, investigations or proceedings pending or,
to the knowledge of Duramed, threatened against, relating to, involving or
otherwise affecting Duramed or any of the Duramed Subsidiaries before any court,
governmental agency, commission, or administrative or regulatory authority
which, in the aggregate, may reasonably be expected to have a material adverse
effect on the Condition of Duramed and the Duramed Subsidiaries taken as a
whole. Neither Duramed nor any Duramed Subsidiary is subject to any order,
judgment, injunction or decree that has or will have a material adverse effect
on the Condition of Duramed and the Duramed Subsidiaries taken as a whole nor,
to the Duramed's knowledge, is any such action, suit, claim, investigation or
proceeding reasonably foreseeable.

         Section 4.11 COMPLIANCE WITH LAWS. Except as set forth or referred to
in the Duramed SEC Filings (including the financial statements and footnotes
thereto), neither Duramed nor any Duramed Subsidiary is in violation (or with or
without notice or lapse of time or both, would be in violation) of any term or
provision of any law or any writ, judgment, decree, injunction or similar order
applicable to Duramed or any Duramed Subsidiary or any of its respective assets
or properties, the result of which violations in the aggregate has or may
reasonably be expected to have a material adverse effect on the Condition of
Duramed and the Duramed Subsidiaries taken as a whole. Except as set forth or
referred to in the Duramed SEC Filings (including the

                                      B-34

<PAGE>   139



financial statements and footnotes thereto), Duramed and each of the Duramed
Subsidiaries have and are in substantial compliance with all material permits,
licenses, orders and approvals of all federal, state, local or foreign
governmental or regulatory bodies required for them to carry out their
businesses as presently conducted except as would not have a materially adverse
effect on Duramed and the Duramed Subsidiaries taken as a whole. All such
permits, licenses, orders and approvals are in full force and effect, and no
suspension or cancellation, nor any proposed adverse modification of any of them
is pending or, to the knowledge of Duramed, threatened except as would not have
a material adverse effect on Duramed and the Duramed Subsidiaries taken as a
whole.

         Section 4.12 EMPLOYEE BENEFIT PLANS, EMPLOYMENT AND RELATED AGREEMENTS.
(a) Each employee benefit plan, as defined in Section 3(3) of ERISA, maintained
currently or in the past by Duramed or any of the Duramed Subsidiaries ("Duramed
Benefit Plans") has been operated and administered in all material respects in
accordance with all applicable requirements of ERISA and the Code. The terms and
conditions of each Duramed Benefit Plan conform in all material respects with
all applicable provisions of ERISA and the Code. Each Duramed Benefit Plan which
is an employee pension benefit plan, as defined in Section 3(2) of ERISA, and
which is intended to be "qualified" within the meaning of Section 401(a) of the
Code ("Duramed Pension Plan"), has been determined by the Internal Revenue
Service to be so qualified. Duramed has no knowledge of any action or claim of
any kind (other than routine claims for benefits) that has been asserted or
threatened against any Duramed Pension Plan, or the assets thereof, or against
any fiduciary of such a Plan; and the Duramed has no knowledge of any
investigation or administrative review of a Duramed Pension Plan which could
result in the imposition of any penalty or assessment.

                  (b) None of the Duramed Pension Plans which is subject to
Title IV of ERISA has completely or partially terminated, or been the subject of
a reportable event as defined in Section 4043 of ERISA. No liability under
Subtitle D of Title IV of ERISA has been incurred by Duramed or any of the
Duramed Subsidiaries with respect to a Duramed Pension Plan.

                  (c) The actuarial present value of the total accrued benefits
under each Duramed Pension Plan which is a defined benefit pension plan did not,
as of its latest valuation date, exceed the fair market value of the total
assets of the Plan, based upon the actuarial assumptions and methods used to
fund the Plan and determined on an ongoing basis. No Duramed Pension Plan has
incurred any accumulated funding deficiency (whether or not waived) as defined
in Section 412 of the Code.

                  (d) Except as set forth in Section 4.12 of the Duramed
Disclosure Schedule, there are no multi-employer plans, as

                                      B-35

<PAGE>   140



defined in Section 4001(a)(3) of ERISA, to which Duramed or any of the Duramed
Subsidiaries contributes, or under which Duramed or any of the Duramed
Subsidiaries has any present or future obligation or liability.

                  (e) No Duramed Benefit Plan provides health, life or other
similar coverage to employees beyond the termination of their employment with
the Duramed, other than coverage that is required under Section 4980B of the
Code, or under the continuation of coverage provisions of the laws of any state.

                  (f) No Duramed Benefit Plan is funded by, or associated with,
a "voluntary employees' beneficiary association" within the meaning of Section
501(c)(9) of the Code.

                  (g) Duramed has filed or caused to be filed on a timely basis
all returns, reports (including Form 5500), statements, notices, declarations
and other documents required by any federal, state, local or foreign
governmental agency (including without limitation the Internal Revenue Service,
the Department of Labor, the Pension Benefit Guaranty Corporation and the
Commission) with respect to each Duramed Benefit Plan. Duramed has delivered or
caused to be delivered to every participant, beneficiary and every other party
entitled to such material all plan descriptions, returns, reports, notices,
statements and similar materials including, without limitation, summary plan
descriptions and reports as are required under Title I of ERISA and the Code.

                  (h) The consummation of the transactions contemplated by this
Agreement will not increase nor accelerate the time of payment or vesting of any
compensation due to any current or former employee of the Duramed, or result in
the payment or series of payments by the Duramed to any person of an "excess
parachute payment" within the meaning of Section 280G of the Code.

         Section 4.13 NO WARRANTY OF FDA APPROVAL. The parties hereby
acknowledge that Duramed makes no representation or warranty in connection with
this Agreement to any Person with respect to the likelihood of approval by FDA
of Duramed's conjugated estrogens product.

         Section 4.14 DISCLOSURE.  No representation or warranty contained in 
this Agreement or the Duramed Disclosure Schedule, and no statement,
certificate, schedule, list or other information furnished or to be furnished by
or on behalf of Duramed to Company in connection with this Agreement, contains
or will contain any untrue statement of a material fact, or omits to state or
will omit to state a material fact necessary in order to make the statements

<PAGE>   147




                  (a) Duramed shall have performed and complied in all material
respects with all obligations and agreements required to be performed and
complied with by it under this Agreement at or prior to the Closing and the

Agreement, and the Company shall have received a Certificate of the President or
a Vice President of Duramed as to the satisfaction of this condition.

                  (b) The Company shall have received an opinion of Taft,
Stettinius & Hollister, or other counsel to Duramed reasonably satisfactory to
the Company, dated as of the date of the Closing and in form and substance
reasonably satisfactory to the Company, substantially to the effect that:

                           (1)      Duramed has been incorporated and is in good
standing under the laws of its state of incorporation.

                           (2)      Duramed has the corporate power and 
corporate authority to enter into this Agreement and consummate the
transactions provided for herein. The execution and delivery of this
Agreement by Duramed, and the consummation by Duramed of the transactions
provided for herein, have been duly authorized by requisite corporate action on
the part of Duramed. This Agreement has been executed and delivered by Duramed
and (assuming this Agreement is a valid and binding obligation of the Company)
is a valid and binding obligation of Duramed enforceable against Duramed in
accordance with its terms, except (A) that such enforcement may be subject to
bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer or
other similar laws now or hereafter in effect relating to creditors' rights

other forms of equitable relief may be subject to equitable defenses and to the
discretion of the court before which any proceeding therefor may be brought.

                           (3)      The execution, delivery and performance at
the Closing Date by Duramed of this Agreement will not (A) conflict with or
result in a breach of any provision of the Certificate of Incorporation or
By-laws of Duramed (B) result in, constitute a violation of or a default under,
or cause the creation of any security interest or lien upon any of the
properties or assets of Duramed or any of the Duramed Subsidiaries pursuant to,
or cause the acceleration of the maturity of any debt or obligation of Duramed
or any of the Duramed Subsidiaries pursuant to, any agreement to which Duramed
or any of the Duramed Subsidiaries is subject and of which such counsel is
specifically aware or (C) insofar as is actually known to such counsel, violate
any law, rule or regulation or any judgment, decree, order, governmental permit
or license to which Duramed is subject.

                                      B-43

<PAGE>   148




                           (4)      To the best knowledge of such counsel,
neither the execution and delivery by Duramed of this Agreement nor the
consummation by Duramed of the transactions contemplated hereby, nor compliance
by Duramed with any of the provisions hereof will require, except for the
applicable requirements of the Securities Act, the Exchange Act and applicable
state securities laws, any consent, approval or authorization of, or notice to,
or declaration, filing or registration with, any governmental or regulatory
authority.

                           (5)      No facts have come to the attention of such
counsel which have led such counsel to believe that (except for the financial
statements and other financial or statistical information contained therein or
the information concerning the Company as to which such counsel expresses no
opinion), at the respective times the Proxy Statement/Prospectus or any
amendments or supplements thereto were mailed to the shareholders of the Company
or at the time of the meeting of the Company's shareholders referred to in
Section 2.1 hereof, the Proxy Statement/Prospectus contained any untrue
statement of a material fact or omitted 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 were made, not misleading.

                           (6)      [The opinion shall set forth the authorized
and outstanding capitalization of Duramed, including shares held in treasury and
reserved for issuance upon the exercise of options and warrants and the
conversion of notes and preferred shares.]
                           (7)      All shares of Duramed Common Stock to be
issued pursuant to the terms of this Agreement have been duly authorized, and,
when issued, will be fully paid and nonassessable and will not be subject to,
nor will they be issued in violation of, any preemptive rights.

         As to any matter contained in such opinion which involves the laws of
any jurisdiction other than the federal laws of the United States or the DGCL,
such counsel may rely upon opinions of counsel, reasonably acceptable to the
Company, admitted to practice in such other jurisdictions. Any opinions relied
upon by such counsel as aforesaid shall be delivered together with the opinion
of such counsel, which shall state that the Company's and such counsel's
reliance thereon is justified. Such opinion may expressly rely as to matters of
fact upon certificates furnished by appropriate officers and directors of
Duramed and the Duramed Subsidiaries and by public officials, and may contain
such limitations as may be reasonable and approved by the Company and its
counsel.

         Section 6.3 CONDITIONS TO OBLIGATIONS OF DURAMED.  The obligations of 
Duramed to conclude the transactions described herein shall be subject to the
fulfillment at or prior to the

                                      B-44

writing by Duramed:

                  (a) The Company shall have performed or complied in all
material respects with all obligations and agreements required to be performed
or complied with by it under this Agreement at or prior to the Closing and the

at and as of such date, except as otherwise contemplated or permitted by this
Agreement, and Duramed shall have received a Certificate of the Chairman of the
Board, the President or a Vice President of the Company as to the satisfaction
of this condition.

                  (b) All consents, approvals and waivers from third parties
required (i) to consummate the transactions contemplated hereby; (ii) to vest in
Duramed good and valid title to the assets described in Section 1.1 hereof (iii)
to assign to Duramed those contracts, leases, permits and other assets which are
non-assignable or which require consent to assignment and (iv) to assign to
Duramed any material governmental permits required to operate the Business in
substantially the same manner in which it has been operated prior to the Closing
shall have been obtained by the Company, or such contracts, leases or permits
shall have been reissued to Duramed.

                  (c) Duramed shall have received an opinion of Hogan & Hartson,
or other counsel to the Company reasonably satisfactory to Duramed, dated as of
the Closing Date and in form and substance reasonably satisfactory to Duramed,
substantially to the effect that:

                           (1)      The Company has been incorporated and is in
good standing as a corporation under the laws of New Jersey.

                           (2)      The Company has the corporate power and
corporate authority to enter into this Agreement and consummate the transactions
provided for herein. The execution and delivery of this Agreement by the
Company, and the consummation by the Company of the transactions provided for
herein, have been duly authorized by all requisite corporate action on the part
of the Company. This Agreement has been executed and delivered by the Company
and (assuming this Agreement is a valid and binding obligation of Duramed) is a
valid and binding obligation of the Company enforceable against the Company in
accordance with its terms, except (A) that such enforcement may be subject to
bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer or other
similar laws now or hereafter in effect relating to creditors' rights generally
and (B) that the remedy of specific performance and injunctive and other forms
of equitable relief may be subject to equitable defenses and to the

                                      B-45

<PAGE>   150



discretion of the court before which any proceeding therefor may
be brought.

                           (3)      The execution, delivery and performance at
the Closing Date by the Company of this Agreement will not (A) conflict with or
result in a breach of any provision of the Certificate of Incorporation or
By-laws of the Company, (B) result in, constitute a violation of or a default
under, or cause the creation of any security interest or lien upon any of the
properties or assets of the Company pursuant to, or cause the acceleration of
the maturity of any debt or obligation of the Company pursuant to, any
agreement, instrument, order, judgment, decree, governmental permit or license
to which the Company is subject which is listed on an attached schedule, which
schedule shall be reasonably acceptable to Duramed, or (C) insofar as is
actually known to such counsel, violate any law, rule or regulation which is
listed on an attached schedule, which schedule shall be reasonably acceptable to
Duramed.

                           (4)      To the best knowledge of such counsel,
neither the execution and delivery by the Company of this Agreement nor the
consummation by the Company of the transactions contemplated hereby nor
compliance by the Company with any of the provisions hereof will require, except
for the applicable requirements of the Securities Act, the Exchange Act and
applicable state securities laws, consent, approval or authorization of, or
notice to, or declaration, filing or registration with, any governmental or
regulatory authority, listed on an attached schedule, which schedule shall be
reasonably acceptable to Duramed.

                           (5)      No facts have come to the attention of such
counsel in the course of its representation of the Company, without any special
investigation, which have led such counsel to believe that (except for the
financial statements and other financial or statistical information contained
therein or the information concerning Duramed, or as set forth on the Company
Disclosure Schedule, as to which such counsel expresses no opinion), at the
respective times the Proxy Statement/Prospectus or any amendments or supplements
thereto were mailed to the shareholders of the Company, or at the time of the
meeting of the Company's shareholders referred to in Section 2.2 hereof, or as
of the Closing Date, the sections of the Proxy Statement/Prospectus related to
the Company and listed in an attached schedule (which schedule shall be
reasonably acceptable to Duramed) contained any untrue statement of a material
fact or omitted 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 were made, not misleading.

                           (6)      The authorized capital stock of the Company
consists of Ten Million shares of Company Common Stock.  As of
__________________, 1996, _______________ shares of Company

                                      B-46

<PAGE>   151



Common Stock are issued and outstanding, and no shares of Company Common Stock
are held in treasury. All of the issued and outstanding shares of capital stock
of the Company are validly issued and fully paid and non-assessable and are not
subject to, nor were they issued in violation of, to such counsel's knowledge,
any preemptive rights.

                           As to any matter contained in such opinion which
involves the laws of any jurisdiction other than the federal laws of the United
States or the DGCL, such counsel may rely upon opinions of counsel, reasonably
acceptable to Duramed, admitted to practice in such other jurisdictions. Any
opinions relied upon by such counsel as aforesaid shall be delivered together
with the opinion of such counsel, which shall state that Duramed's and such
counsel's reliance thereon is justified. Such opinion may expressly rely as to
matters of fact upon certificates furnished by appropriate officers and
directors of the Company and by public officials, and may contain such
limitations as may be reasonable and are approved by Duramed and its counsel.

                  (d) If the Proxy Statement/Prospectus prepared in connection
with the transactions contemplated hereby shall contain any unaudited interim
financial statements of the Company, or any pro forma financial statements
prepared in part with data from such unaudited interim financial statements,
Duramed shall have received, if requested, "comfort" letters from the Company's
independent certified public accountants, dated (i) the effective date of the
Registration Statement and (ii) the Closing, in each case substantially to the
effect that:

                           (i)  They are a firm of independent public
accountants with respect to the Company within the meaning of the
Exchange Act;

                           (ii)  In their opinion the audited financial
statements of the Company examined by them and included in the Proxy
Statement/Prospectus comply as to form in all material respects with the
applicable requirements of the Exchange Act;

                           (iii)  On the basis of specified procedures (which
do not constitute an examination in accordance with generally accepted auditing
standards), consisting of a reading of the unaudited financial statements of the
Company included in such Proxy Statement/Prospectus and of the latest available
unaudited financial statements of the Company, inquiries of officers and a
reading of the minutes of meetings of shareholders and the Board of Directors of
the Company, nothing has come to their attention which causes them to believe:
(x) that the unaudited financial statements of the Company included in the Proxy
Statement/Prospectus do not comply as to form in all material respects with the
applicable accounting requirements of the Exchange Act, (y) that any such
unaudited financial statements

                                      B-47

<PAGE>   152



are not, or any unaudited financial statements of the Company from which pro
forma financial information set forth in the Proxy Statement/Prospectus has been
derived are not, fairly presented in all material respects in conformity with
GAAP and on a basis substantially consistent with that of the audited financial
statements or (z) that during the period from December 31, 1995 to a date five
days before the Closing, there was any change in the capital stock or any
increase in long term debt of the Company as compared to the amounts shown in
the balance sheet as of December 31, 1995 included in the audited financial
statements of the Company as of such date, or that during the period from the
date of such balance sheet to the most recent month-end for which financial
statements are available there was any material decrease in net assets or any
material decrease, as compared with the corresponding period in the preceding
year, in net income of the Company, except in all instances for changes or
decreases which are set forth in such letter.

                  (e) The Company shall have complied with all applicable 
requirements of the Industrial Site Recovery Act, N.J. Stat. Ann. ss.13:K-6 et
seq. ("ISRA"), and Duramed shall have received evidence of such compliance
reasonably satisfactory to Duramed.

                  (f) The existing Employment Agreements between the Company and
the employees of the Company listed on Exhibit 6.2(c) shall be in full force and
effect and assigned to and assumed by Duramed, or, at Duramed's option, new
Employment Agreements between Duramed and such employees shall have been
executed in a form to be negotiated between Duramed and such employees prior to
the mailing of the Prospectus/Proxy Statement and shall be in full force and
effect, and all other employment agreements relating to employees of the Company
whom Duramed desires to hire shall have been terminated.

                  (g) In order to assure compliance with Rule 145(a)(3)(C)
promulgated under the Act, the Board of Directors of the Company shall have
adopted a plan providing for (i) the pro-rata or similar distribution of the
Purchase Consideration to the shareholders, optionholders, noteholders and
remaining creditors of the Company; or (ii) the dissolution of the Company.

                                    ARTICLE 7

<PAGE>   153



                  (b) by either Duramed or the Company if there has been a
material breach of any representation, warranty, covenant or agreement on the
part of the other set forth in this Agreement which breach has not been cured
within ten (10) business days following receipt by the breaching party of notice
of such breach from the nonbreaching party; PROVIDED that, in the case of any
such breach that is susceptible of cure but that cannot with diligence be cured
within such ten (10) business day period, if the party in breach shall promptly
have commenced to cure the same and shall thereafter prosecute the curing
thereof with reasonable diligence, the period within which such breach may be
cured shall be extended for such further period as shall be necessary for the
curing thereof with reasonable diligence;

                  (c) by either Duramed or the Company if any permanent
injunction or other order of a court or other competent authority enjoining or
otherwise preventing the consummation of the transactions contemplated hereby
shall have become final and non-appealable;

                  (d) by either Duramed or the Company if the transactions
contemplated hereby shall not have been consummated before September 30, 1996;

                  (e) by either Duramed or the Company if the Required Company
Vote shall not have been obtained by reason of the failure to obtain the
required vote upon a vote held at a duly held meeting of shareholders or at any
adjournment thereof;

                  (f) by Duramed if the Board of Directors of the Company shall
or shall resolve to (i) not recommend, or withdraw its approval or
recommendation of this Agreement or any of the transactions contemplated hereby,
(ii) modify such approval or recommendation in a manner adverse to Duramed or
any of its affiliates or (iii) adopt a Third Party Resolution (as defined in
Section 7.1(g)); or

                  (g) by the Company if a corporation, partnership, person or
other entity or group (other than Duramed or any of its affiliates) (a "Third
Party") shall have made a bona fide proposal (a "Third-Party Proposal") to
acquire (by means of a tender or exchange offer, merger, consolidation, business
combination or otherwise) all or a substantial portion of the outstanding shares
of Company Common Stock or of the assets of the Company, taken as a whole, and
the Board of Directors of the Company adopts a resolution (a "Third-Party
Resolution") that states that the Board of Directors believes in good faith that
such a proposal is more favorable, from a financial point of view, to the
holders of Company Common Stock than the transactions contemplated hereby;
PROVIDED that the Company shall, prior to such termination, provide Duramed with
notice of the terms and conditions of such Third-Party Proposal and the identity
of such Third Party.

         Section 7.2 EFFECT OF TERMINATION. In the event of termination of this
Agreement by either Duramed or the Company as provided in Section 7.1, this
Agreement shall forthwith become void and have no effect, without any liability
or obligation on the part of Duramed or the Company or their respective officers
or directors, except (x) with respect to Sections 5.8 and 7.3 and Article 8 and
(y) to the extent that such termination results from the willful and material
breach by a party hereto of any of its representations, warranties, covenants or
agreements set forth in this Agreement.
           
         Section 7.3 REPURCHASE OF CAPTOPRIL AND OTHER DRUGS RIGHTS. If this
Agreement is terminated by either party hereto in accordance with its terms,
except in the case of termination pursuant to Section 7.1(b) hereof by Duramed
due to a material and willful breach of this Agreement by the Company, the
Company shall have the right (but not the obligation) to repurchase from Duramed
all rights in and to the Company's Captopril and the drug(s) listed on Exhibit
10 attached hereto transferred to Duramed pursuant to a Distribution Agreement
dated October 4, 1995 and a letter agreement dated January 26, 1996,
respectively. In exchange for such rights, the Company shall repay in full all
amounts advanced to the Company by Duramed pursuant to Section 2.5 of this
Agreement, together with interest accrued on such amounts to the date of such
repurchase, less any amounts then outstanding under invoices for goods shipped
by the Company to Duramed pursuant to either of such agreements, but not yet
paid by Duramed. The Company may exercise its rights under this Section 7.3 by
written notice to Duramed within thirty (30) days of the final termination of

any of the representations and warranties of the Company in this Agreement, or
in any certificate delivered by the Company pursuant to this Agreement, or any

otherwise assert any such claim against the Company or its shareholders.

     any loss, claim, damage, liability (including any federal, state or local

     action taken or the failure to take action by the officers on behalf of
     Corporation other than actions constituting willful misconduct or fraud.

  Item 20.  Indemnification of Directors and Officers

   
         Section 145 of the General Corporation Law of the State of Delaware
allows indemnification by the registrant to any person made or threatened to be
made a party to any proceedings, other than a proceeding by or in the right of
the registrant, by reason of the fact that such person is or was a director,
officer, employee or agent of the registrant, or was serving at the request of
the registrant in a similar capacity with another corporation or other entity,
against expenses, including judgments and fines, if that person acted in good
faith and in a manner reasonably believed to be in or not opposed to the best
interests of the registrant and, with respect to criminal actions, in which that
person had no reasonable cause to believe that such person's conduct was
unlawful. Similar provisions apply to actions brought by or in the right of the
registrant, except that no indemnification shall be made in such cases when the
person shall have been adjudged to be liable for negligence or misconduct to the
registrant unless deemed otherwise by the court in which the action was brought.
Indemnification is to be made by a majority vote of a quorum of disinterested
directors or other written opinion of independent counsel or by the shareholders
or by the court.
    



         Section 145 also authorizes the registrant to purchase insurance
against such liabilities.

         The registrant's Certificate of Incorporation extends similar rights 
of indemnification.

Item 22.  Undertakings

     (b) *The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

     (g) *(1) The undersigned registrant hereby undertakes as follows: that 
prior to any public reoffering of the securities registered hereunder through
use of a prospectus which is a part of this registration statement, by any
person or party who is deemed to be an underwriter within the meaning of Rule
145(c), the issuer undertakes that such reoffering prospectus will contain the
information called for by the applicable registration form with respect to
reofferings by persons who may be deemed underwriters, in addition to the
information called for by the other items of the applicable form.
        
   
         (2) The registrant undertakes that every prospectus (i) that is filed
pursuant to paragraph (1) immediately preceding, or (ii) that purports to meet
the requirements of section 10(a)(3) of the Act and is used in connection with
an offering of securities subject to Rule 415, will be filed as a part of an
amendment to the registration statement and will not be used until such
amendment is effective, and that, for purposes of determining any liability
under the Securities Act of 1933, each such post-effective amendment shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.
    

     (h) *Insofar as indemnification for liabilities arising under the 
Securities Act may be permitted to directors, officers, and controlling persons
of the registrant pursuant to the provisions of Item 20 hereof, or otherwise,
the registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer, or controlling
person of the registrant in the successful defense of any action, suit, or
proceeding) is asserted by such director, officer, or controlling person in
connection with the securities being registered, the registrant will, unless in
the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the Act and
will be governed by the  final adjudication of such issue.
        
     The undersigned registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Items 4, 10(b), 11, or 13 of this Form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or 
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the registration statement through
the date of responding to the request.
        
     The undersigned registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it becomes effective.

Preferred Stock") as set forth in the Terms attached hereto, and, pursuant
thereto, the Board hereby authorizes the adoption and filing of a Certificate of
Amendment of Series D Convertible Preferred Stock with terms as attached hereto.

          TERMS OF 8% CUMULATIVE CONVERTIBLE PREFERRED STOCK, SERIES D
                DURAMED PHARMACEUTICALS, INC.(the "Corporation")

         1. DESIGNATION AND AMOUNT. There is hereby established a series of
Preferred Stock to be designated as the "8% Cumulative Convertible Preferred
Stock, Series D" (the "Series D Convertible Preferred Stock") and the number of
shares which shall constitute such series shall be 200,000 shares, with a stated
value (the "Stated Value") of $100 per share.

         2. DIVIDENDS.
            ----------
            (a) GENERAL. The holders of the Series D Convertible Preferred
Stock shall be entitled to receive, when and as declared by the Board of
Directors out of funds legally available therefor, cumulative preferential cash
dividends, at the rate of 8% of the Stated Value per annum from the date of
issuance (with appropriate proration for any partial dividend period). Such
cumulative dividends shall be payable quarterly in arrears on the fifteenth day
of each January, April, July and October, commencing October 15, 1996.

            (b) DIVIDENDS CUMULATIVE. Dividends on the Series D
Convertible Preferred Stock shall accrue and be cumulative from the date of
issuance, whether or not earned and whether or not in any dividend period there
shall be surplus or net profits of the Corporation legally available for the
payment of such dividends.

            (c) EQUALITY OF SHARES. No dividend shall be declared or set
apart for any shares of the Series D Convertible Preferred Stock for any period
unless at the same time a like proportionate dividend for the same period shall
be declared or set apart for all shares of the Series D Convertible Preferred
Stock then outstanding and entitled to receive such dividend.

            (d) RESTRICTIONS WITH RESPECT TO JUNIOR SHARES. So long as any
shares of the Series D Convertible Preferred Stock shall remain outstanding, no
dividend shall be declared or paid or set apart for payment on the Common Stock
or any other class of stock ranking junior to the Series D Convertible Preferred
Stock in either payment of dividends or liquidation (all such junior classes of
stock including, without limitation, the Common Stock, hereinafter referred to
collectively as the "Junior Stock") unless full dividends (including interest on
any accumulations of dividends) on all outstanding shares of Series D
Convertible Preferred Stock shall have been paid in full for all past dividend
periods and the dividends on all outstanding shares of Series D Convertible
Preferred Stock for the then current dividend period shall have been paid or
declared and sufficient funds set apart for payment thereof.

         3. LIQUIDATION PREFERENCE.
            -----------------------
            (a) GENERAL.  The Series D Convertible Preferred Stock shall be
preferred over the Common Stock and any other class or series of Junior Stock.
In the event of any liquidation or dissolution or winding up of the 
Corporation, the


<PAGE>   4



holders of the Series D Convertible Preferred Stock shall be entitled to
receive, after payment or provision for payment of the debts and other
liabilities of the Corporation, out of the assets of the Corporation available
for distribution to its shareholders, all accumulated and unpaid dividends
before any distribution of the assets shall be made to the holders of the Common
Stock or any other class or series of Junior Stock. After payment of accumulated
dividends on the Series D Convertible Preferred Stock shall have been made in
full as provided in the preceding sentence, but not prior thereto, the Preferred
Stock, the Common Stock and any other series or class of Junior Stock shall,
subject to the respective terms and provisions, if any, applying thereto, be
entitled to receive any and all assets remaining to be paid or distributed, with
the Series D Convertible Preferred Stock sharing therein in an amount per share
of Series D Convertible Preferred Stock equal to the amount to be distributed on
each share of Common Stock multiplied by a fraction the numerator of which is
the Stated Value of such share of Series D Convertible Preferred Stock and the
denominator of which is the then Conversion Price.

                  (b) DISTRIBUTIONS PRO RATA. If upon any liquidation or
dissolution or winding up of the Corporation the amounts payable on or with
respect to the Series D Convertible Preferred Stock together with the amounts
payable on or with respect to all classes or series of stock ranking on a parity
with the Series D Convertible Preferred Stock as to distribution of assets are
not paid in full, the holders of shares of Series D Convertible Preferred Stock
together with all classes or series of stock ranking on a parity with the Series
D Convertible Preferred Stock as to distribution of assets shall share pro rata
in any distribution of assets in respect of the shares held by them upon such
distribution in proportion to the amounts that would have been distributable to
each such class or series if all amounts payable on or with respect to the
Series D Convertible Preferred Stock and any other class or series of stock that
so ranks on a parity with the Series D Convertible Preferred Stock had been paid
in full.

                  (c) MERGER OR CONSOLIDATION. Neither the merger or
consolidation of the Corporation with another corporation nor the sale or lease
of all or substantially all of the assets of the Corporation shall be deemed to
be a liquidation or dissolution or winding up of the Corporation.

                  (d) NOTICE REQUIRED. Written notice of any voluntary or
involuntary liquidation, dissolution or winding up of the affairs of the
Corporation, stating the payment date and the place where the distributable
amount shall be payable and stating the anticipated amount of any such
distributable amount, shall be given by mail, postage prepaid, not less than
thirty (30) days prior to the payment date stated therein, to the holders of
record of the Series D Convertible Preferred Stock at their respective addresses
as the same shall then appear on the books of the Corporation.

         4.       CONVERSION.
                  -----------
                  (a) GENERAL. Shares of Series D Convertible Preferred Stock
may be converted at the option of the holder thereof, or otherwise as provided
below, into fully paid and nonassessable shares of Common Stock of the
Corporation at a price (the "Conversion Price") equal to 85% of the Market Price
(as defined below) per

                                      - 2 -

<PAGE>   5



share of Common Stock on the date of conversion (but the Conversion Price shall
be not less than $7.00 per share (the "Minimum Price") or greater than $20.00
per share (the "Maximum Price")) with respect to the Stated Value of each share
of Series D Convertible Preferred Stock, together with all accrued but unpaid
dividends thereon. Such option may be exercised by any holder on or after
October 16, 1996. Except as provided in Section 6, any shares of Series D
Convertible Preferred Stock not converted into Common Stock prior to July 18,
1998 shall be automatically converted on such date without any action of the
holder thereof. The Market Price per share of Common Stock on any date shall be
deemed to be the average of the daily closing prices for the 10 consecutive
trading days ending on the trading day prior to the day in question. "Closing
price" on any day when used with respect to the Common Stock means the reported
closing bid price therefor as reported by Bloomberg, L.P., or if not so reported
the closing bid price as furnished by any member of the National Association of
Securities Dealers, Inc. selected from time to time by the Corporation for that
purpose. Notwithstanding the foregoing, the maximum number of shares of common
stock which may be issued upon conversion of the shares of Series D Convertible
Preferred Stock (the "Maximum Number of Shares of Common Stock") shall not
exceed 2,130,895. Shares of Series D Convertible Preferred Stock which remain
outstanding after the issuance of the Maximum Number of Shares of Common Stock
shall no longer be convertible into shares of Common Stock but shall instead be
subject to redemption as provided in Section 6 hereof. The Maximum Number of
Common Shares shall be subject to adjustment as provided in Section 4(b)(i).

                  (b) ADJUSTMENTS. The Minimum and Maximum Prices, the Maximum
Number of Shares of Common Stock and the kind and amounts of securities and
property for which the shares of Series D Convertible Preferred Stock may be
converted shall be subject to adjustment from time to time as follows:

                      (i) If, at any time after the issuance of the Series
D Convertible Preferred Stock, the Corporation shall (A) declare or pay a
dividend, or make a distribution, to all holders of its Common Stock in shares
of Common Stock, (B) subdivide its outstanding shares of Common Stock into a
greater number of shares, (C) combine its outstanding shares of Common Stock
into a smaller number of shares, or (D) issue by reclassification of its shares
of Common Stock (other than a subdivision or combination thereof or a change in
par value) any securities, the Maximum Price and the Minimum Price and the
Maximum Number of Shares of Common Stock in effect immediately prior to such
action shall be adjusted so that the holder of any share of Series D Convertible
Preferred Stock thereafter surrendered for conversion shall be entitled to
receive the kind and number of shares of Common Stock of the Corporation and/or
other securities which he would have owned or been entitled to receive
immediately following such action had such share of Series D Convertible
Preferred Stock been converted immediately prior thereto. Any adjustment made
pursuant to this Paragraph (b)(i) shall become effective immediately after the
record date in the case of a dividend or distribution and shall become effective
immediately after the effective date in the case of a subdivision, combination
or reclassification.


                                      - 3 -

<PAGE>   6



                           (ii)  If, at any time after the date of issuance of
the Series D Convertible Preferred Stock, the Corporation shall distribute to
all or substantially all holders of its Common Stock either (A) evidences of
indebtedness or assets (excluding cash dividends or distributions) or (B) any
other securities of the Corporation or any rights, warrants or options to
subscribe for, purchase or otherwise acquire securities of the Corporation in a
transaction not covered by Paragraph (b)(i) above (any of which are referred to
herein as "Other Securities"), then and in any such case the Corporation shall
either distribute such Other Securities to the holders of the Series D
Convertible Preferred Stock or reserve for the benefit of the holders of the
Series D Convertible Preferred Stock such amount of such Other Securities as the
holders of all Series D Convertible Preferred Stock then outstanding would have
owned or been entitled to receive immediately following such action had the
shares of Series D Convertible Preferred Stock been converted into shares of
Common Stock immediately prior thereto. In addition, the Corporation shall
either distribute to, or reserve for the benefit of, the holders of the Series D
Convertible Preferred Stock any principal, interest, dividends or other property
payable with respect to such Other Securities as and when such interest,
dividends or other property is distributed to the holders of Common Stock. If
such a reserve is made, as and when each such share of Series D Convertible
Preferred Stock is converted, the holder of such share shall be entitled to
receive from the Corporation his share of such Other Securities together with
the principal, interest, dividends or other property payable with respect
thereto.

                           (iii)  All calculations under this Section 4 shall 
be made to the nearest one-tenth of a cent or to the nearest one thousandth of a
share, as the case may be. No adjustment shall be required unless such
adjustment would result in an increase or decrease of at least one percent (1%)
of the Minimum Price and the Maximum Price or the Maximum Number of Shares of
Common Stock; provided, however, that any adjustments which by reason of this
subparagraph (iii) are not required to be made shall be carried forward and
taken into account in any subsequent adjustment.

                           (iv)  Whenever the Minimum Price and the Maximum 
Price and Maximum Number of Shares of Common Stock are adjusted or Other
Securities are reserved as herein provided, the Corporation shall mail or cause
to be mailed a copy of a statement, verified by its independent certified public
accountants, setting forth the required adjustments or the nature and amount of
Other Securities, as the case may be, to each person who is a registered holder
of Series D Convertible Preferred Stock at such person's last address as the
same appears on the books of the Corporation. Each adjustment shall remain in
effect until a subsequent adjustment is required hereunder. Failure to give or
receive such notice or any defect therein shall not affect the legality or
validity of any action taken. Following any adjustment to the Minimum Price and
the Maximum Price and the Maximum Number of Shares of Common Stock, the holders
of the Series D Convertible Preferred Stock shall be entitled, by themselves or
through attorneys or accountants retained by them, to inspect the books and
records of the Corporation in order to verify such adjustment. Such inspection
shall be at the expense of the holders of the Series D Convertible Preferred
Stock requesting such inspection unless such inspection reveals an error in the
adjustment equal to 5% or more of the Minimum Price and the Maximum Price

                                      - 4 -

or the Maximum Number of Shares of Common Stock, in which case the Corporation
shall promptly reimburse the holders for all expenses incurred in connection
therewith.

                           (v)  If at any time, as a result of an adjustment 
made pursuant to Paragraph (ii) above, the holders of Series D Convertible
Preferred Stock shall become entitled to receive upon conversion any Other
Securities, thereafter the number of such Other Securities receivable upon
conversion of the Series D Convertible Preferred Stock and the price of the
Other Securities shall be subject to adjustment from time to time and in a
manner and on terms as nearly equivalent as practicable to the provisions with
respect to Series D Convertible Preferred Stock contained in Paragraphs (i) and
(ii), above.

                  (c) MERGER OR CONSOLIDATION. In case of a merger or
consolidation of the Corporation with or into another corporation, or the sale
or transfer of all, or substantially all, of the property or assets of the
Corporation, the holders of shares of Series D Convertible Preferred Stock shall
thereafter have the right to convert each of such shares into the kind and
amount of shares of stock or other securities and property (including cash)
receivable (the "Consideration") upon such merger, consolidation or sale by a
holder of the number of shares of Common Stock (whether whole or fractional)
into which such shares of Series D Convertible Preferred Stock might have been
converted immediately prior to such merger, consolidation or sale (all of which
Consideration shall be reserved and become payable upon conversion in the same
manner as for Other Securities pursuant to Paragraph (b)(ii) above and shall be
adjusted as provided in Paragraph (b) above), and shall have no other conversion
rights under these provisions and, in addition, the Corporation shall reserve,
on a current basis as and when distributed, for payment upon conversion, in the
same manner as required for Other Securities pursuant to Paragraph (b)(ii)
above, any interest, dividends, other stock, securities or property
distributable with respect to the Consideration, the same as if such shares of
Series D Convertible Preferred Stock had been converted immediately prior to
such merger, consolidation, or sale of assets; and effective provision shall be
made in the charter of the resulting or surviving corporation or otherwise, so
that the provisions set forth herein for the adjustment of the conversion terms
of the Series D Convertible Preferred Stock shall thereafter be applicable, as
nearly as reasonably may be, to any of the Consideration deliverable upon
conversion of Series D Convertible Preferred Stock remaining outstanding or
other convertible preferred stock received in place thereof. Any such resulting
or surviving corporation shall expressly assume the obligation to deliver the
Consideration, upon the exercise of the conversion right, (and, to that end,
shall reserve sufficient Consideration to issue, distribute and/or pay the
holders of the Series D Convertible Preferred Stock as if all such stock were
converted) as holders of Series D Convertible Preferred Stock remaining
outstanding, or other convertible preferred stock received by such holders in
place thereof, shall be entitled to receive pursuant to the provisions hereof,
and to make provision for protection of conversion rights as above provided.

                  (d) NOTICES. If, at any time while shares of Series D
Convertible Preferred Stock are outstanding, the Corporation shall (i) declare a
dividend (or any other distribution) on its Common Stock, other than in cash, or
(ii) reclassify its Common Stock (other than through a subdivision or
combination thereof or a change

                                      - 5 -

in par value) or become a party to any consolidation or merger or sale or
transfer of all or substantially all of the assets of the Corporation, for which
approval of the holders of its stock is required, then the Corporation shall
cause to be mailed to registered holders of Series D Convertible Preferred
Stock, at their last addresses as they shall appear on the books of the
Corporation, at least thirty (30) days prior to the applicable record date
hereinafter specified, a notice stating (x) the date on which a record is to be
taken for the purpose of such dividend or distribution, or, if a record is not
to be taken, the date as of which holders of Common Stock of record to be
entitled to such dividend or distribution are to be determined, or (y) the date
on which any such reclassification, consolidation, merger, sale or transfer is
expected to become effective, and the date as of which it is expected that
holders of record of Common Stock shall be entitled to exchange their Common
Stock for securities or other property, if any, deliverable upon such
reclassification, consolidation, merger, sale or transfer. Failure to give or
receive the notice required by this Paragraph (d) or any defect therein shall
not affect the legality or validity of any such dividend, distribution,
reclassification, consolidation, merger, sale, transfer or other action.

                  (e) EXERCISE OF CONVERSION RIGHTS. The holder of any shares of
Series D Convertible Preferred Stock may exercise his option to convert such
shares into shares of Common Stock only by surrendering for such purpose to the
Corporation the certificates representing the shares to be converted,
accompanied or preceded by written notice (which may be transmitted by
telecopier) that such holder elects to convert such shares in accordance with
the provisions of this Section 4. Said notice shall also state the name or names
(with addresses) in which the certificate or certificates for shares of Common
Stock which shall be issuable on such conversion shall be issued. Each
certificate or certificates surrendered for conversion shall, unless the shares
issuable on conversion are to be issued in the same name as that in which such
certificate or certificates are registered, be accompanied by instruments of
transfer, in form satisfactory to the Corporation, duly executed by the holder
or his duly authorized attorney. Each conversion shall be deemed to have been
effected on the date on which such notice shall have been received by the
Corporation as aforesaid, provided that the certificates to which such notice
relates are received by the Corporation no later than the third business day
following the date of receipt of such notice, and the person or persons in whose
name or names any certificate or certificates for shares of Common Stock shall
be issuable upon such conversion shall be deemed to have become on said date the
holder or holders of record of the shares represented thereby notwithstanding
that the transfer books of the Corporation may then be closed or that
certificates representing such shares of Common Stock shall not then be actually
delivered to such person. Within three business days after receipt of the
certificates representing the shares to be converted and the notice of
conversion, the Corporation shall issue and deliver to the person or persons
entitled to receive the same a certificate or certificates representing the
number of shares of Common Stock issuable upon such conversion and shall pay or
cause the payment of such Other Securities or Consideration or other property as
may be payable upon conversion pursuant to Paragraphs (b)(iii) or (c) of this
Section 4.

                  (f) FRACTIONAL SHARES.  No fractional shares of Common Stock 
shall be issued in connection with the conversion of shares of Series D
Convertible Preferred

                                      - 6 -

<PAGE>   9



Stock into Common Stock. Instead of any fractional share of Common Stock which
would otherwise be issuable on conversion, the Corporation shall pay a cash
adjustment with respect to such fractional share computed on the basis of the
then current fair market value of the Common Stock, as determined in good faith
by the Corporation's Board of Directors.

                  (g) TAX ON CONVERSION. The issuance of stock certificates on
conversions of shares of Series D Convertible Preferred Stock shall be made
without charge to converting shareholders for any tax in respect of the issuance
thereof except any tax on the income or gain derived by the converting
shareholders as a result of the issuance thereof. The Corporation shall not,
however, be required to pay any tax which may be payable in respect of any
registration of transfer involved in the issue and delivery of stock in any name
other than that of the holder of the shares of Series D Convertible Preferred
Stock converted, and the Corporation shall not be required to so issue or
deliver any stock certificate unless and until the person or persons requesting
the registration of transfer shall have paid to the Corporation the amount of
such tax or shall have established to the satisfaction of the Corporation that
such tax has been paid.

                  (h) SECURITIES RESERVED. The Corporation shall at all times
reserve and keep available out of its authorized Common Stock (and any Other
Securities or Consideration or property) the full number of shares of Common
Stock (and any Other Securities or Consideration or property) deliverable upon
the conversion of all outstanding shares of Series D Convertible Preferred
Stock. The Corporation shall not enter into any agreement or take any action
which would impair or restrict its legal authority to issue such shares of
Common Stock, Other Securities or Consideration or property upon conversion or
to defeat in any way the right of the holders of the Series D Convertible
Preferred Stock to receive such consideration upon conversion. In addition,
whenever the Corporation is required to reserve any interest, dividends or other
property payable upon conversion of the Series D Convertible Preferred Stock,
the Corporation shall, as to cash, deposit such amounts in one or more separate
accounts for the sole benefit of the holders of the Series D Convertible
Preferred Stock upon conversion and, as to other property, physically segregate
or otherwise set such property aside in such a manner as to protect the rights
of the holders of the Series D Convertible Preferred Stock to the receipt of
such property upon conversion.

                  (i) EFFECT OF CONVERSION. All shares of Series D Convertible
Preferred Stock which shall have been converted into shares of Common Stock
shall assume the status of authorized but unissued shares of Preferred Stock
undesignated as to series.

         5.       Voting Rights.
                  --------------
                  No holder of Series D Convertible Preferred Stock shall be
entitled to vote on any matter submitted to the shareholders of the Corporation
for their vote, waiver, release or other action, except as may be otherwise
expressly required by law.

         6.       Redemption.

                  Within five days after issuance by the Corporation of the
Maximum Number of Shares of Common Stock upon conversion of shares of Series D
Convertible Preferred Stock, the Corporation shall provide notice of such event
to registered holders of Series D Convertible Preferred Stock, at their last
known addresses as they shall appear on the books of the Corporation. Effective
the date of such mailing, holders of shares of Series D Convertible Preferred
Stock which then remain outstanding may cause such shares to be redeemed by the
Corporation at an amount equal to the Redemption Value (as hereinafter defined)
of such shares. The holder of any shares of Series D Convertible Preferred Stock
may exercise his option to redeem such shares only by surrendering for such
purpose to the Corporation the certificates representing the shares to be
redeemed, accompanied or preceded by written notice (which may be transmitted by
telecopier) that such holder elects to redeem such shares in accordance with the
provisions of this Section 6. Said notice also shall state the name or names
(with addresses) in which any shares of Series D Convertible Preferred Stock
represented by the certificates surrendered which are not to be redeemed shall
be re-issued. Each redemption shall be deemed to have been effective on the date
on which such notice shall have been received by the Corporation as aforesaid,
provided that the certificates to which such notice relates are received by the
Corporation no later than the third business day following the date of receipt
of such notice. Within three business days after receipt of the certificates
representing the shares to be redeemed and the notice of redemption, the
Corporation shall issue and deliver to the person or persons entitled to receive
the same the Redemption Value of the shares to be redeemed. The Redemption Value
of the shares of Series D Convertible Preferred Stock being redeemed shall be
calculated by dividing the aggregate stated value of such shares by the
Conversion Price which would be applicable if such shares were being converted
into shares of common stock as provided in Section 4(a) on the date of
redemption and multiplying the result by the Market Price per share of common
stock on the date of redemption (provided that the Conversion Price shall not be
less than the Minimum Price or greater than the Maximum Price). Any shares of
Series D Convertible Preferred Stock which remain outstanding following the
issue of the Maximum Number of Shares of Common Stock shall be redeemed
automatically without requirement for any further action by either the holder
thereof or the Corporation on July 18, 1998 at an amount equal to the Redemption
Value on such date.

         7.       Amendment.
                  ---------
                  Notwithstanding the provisions of Section 5 above, so long as
any share of Series D Convertible Preferred Stock is outstanding, the Articles
of Incorporation of the Corporation shall not be amended in any manner which
would materially alter or change the powers, preferences or special rights of
the Series D Convertible Preferred Stock so as to affect them adversely without
the affirmative vote of the holders of a majority of the outstanding shares of
Series D Convertible Preferred Stock, voting separately as a class.
