                                     Based on the April 10, 1996 closing
                                     price (the day prior to signing the
                                     Asset Purchase Agreement) of $18.88 per

                                     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,

                                     obligations, other than those to be
                                     assumed by Duramed. Hallmark
                                     estimates that approximately 254,576
                                     shares of Duramed Common Stock and
                                     400,000 Warrants will be available
                                     for distribution to its
                                     shareholders.

OUTSTANDING DURAMED
COMMON STOCK...........              As of June 10, 1996, there were
                                     outstanding 10,120,564 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 6.3% (10.3% 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 --

                                     The Asset Purchase Agreement is
                                     subject to termination at the option
                                     of either Duramed or Hallmark if the
                                     Transaction is not consummated on or

APPRAISAL RIGHTS......               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

                               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 bid quotations 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 reflect inter-dealer prices, without retail mark-up, mark-down or 
commission, and may not necessarily represent actual transactions.

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 August 2, 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 ($2,986,520 at June 10, 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 254,576 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

                                     - 12 -

<PAGE>   24



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 June 10, 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.


                                     - 13 -

<PAGE>   25

         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.

         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

                                     - 15 -

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.


                                     - 16 -

<PAGE>   28

                  (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
strategic partner or joint venture partner or other source for operating funds.

                  (h) Industry trends toward consolidation of suppliers and 
the perceived willingness of customers to deal only with a limited number of 
suppliers.

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
June 10, 1996, $107,880 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. The Lease Agreements will be canceled, and
Duramed will not assume any liability for unpaid rental obligations.


                                     - 17 -

<PAGE>   29


         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 June 10, 1996 was $224,997. 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
June 10, 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. Vish Raju, 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 June 10, 1996, Hallmark owed
Duramed $2,986,520, 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

                                     - 18 -

<PAGE>   30


such other product. By June 10, 1996, Duramed had advanced $226,508 towards
the cost of this biostudy, which amount is included in the $2,986,520 owed by
Hallmark to Duramed at that date.


                                 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
and interest in and to the assets used in its business, including without
limitation, all real property leases, leasehold improvements, equipment,
personal property, inventory, furniture, fixed assets, fixtures, raw materials,
supplies and other tangible property, governmental licenses, permits and
authorizations, contracts, agreements, leases, intellectual property, cash, bank
accounts, accounts receivable, insurance policies, all rights in and to the name
"Hallmark Pharmaceuticals, Inc." and all goodwill.

PURCHASE PRICE

         At the Closing, Duramed will issue 640,000 shares of Duramed Common
Stock and the 400,000 Warrants, less certain amounts thereof to be placed in
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 debt ($1,256,351 at June 10,
1996), and will release all of Hallmark's indebtedness to Duramed ($2,986,520 at
June 10, 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

                                     - 19 -

<PAGE>   31



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

CONDITIONS; WAIVERS

         The respective obligations of Hallmark and Duramed to effect the
Transaction are subject to the satisfaction of certain conditions at or prior to
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

order or taken any action prohibiting or seeking to prohibit or adversely affect
the consummation of the transactions contemplated by the Asset Purchase
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

authorities in connection with 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

                                     - 22 -

<PAGE>   34


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 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.

                                     - 23 -

<PAGE>   35


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 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

                                     - 24 -

<PAGE>   36


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 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

                                     - 25 -

<PAGE>   37


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 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

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 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

                                     - 27 -

<PAGE>   39


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 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.

         Other information concerning Duramed is incorporated herein by 
reference.  See "AVAILABLE INFORMATION" and "DOCUMENTS INCORPORATED BY 
REFERENCE."


                         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

                                     - 29 -

<PAGE>   41



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 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.

                                     - 30 -

<PAGE>   42

         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.

<PAGE>   43


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.

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).

                                     - 32 -

<PAGE>   44


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
June 10, 1996, the record date for the Special Meeting, there were 6,156,240
shares of common stock

                                     - 33 -

<PAGE>   45


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 June 10, 1996, of each person
known by Hallmark to be beneficial owners of more than 5% of the outstanding
Common Stock, each Named Officer, 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" 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 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 10,120,564 shares were issued and outstanding as of June 10,
1996. An additional 3,706,683 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

                                     - 39 -

<PAGE>   51



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. Subsequent to December 31, 1995, the bank converted
42,130 shares of Series B Convertible Preferred Stock into 421,300 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 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

                                     - 40 -

<PAGE>   52



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 June 10, 1996, 195,000 shares of the Series C Preferred Stock
had been converted into 1,340,598 shares of the Duramed Common Stock at an
average conversion price of $14.55 per share of Duramed Common Stock.

    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.

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

                                     - 41 -

<PAGE>   53




    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).

    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

                                     - 42 -

<PAGE>   54



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 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;

                                     - 43 -

<PAGE>   55



(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.

    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

                                     - 44 -

<PAGE>   56



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.

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.

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 above cost, as defined in the agreement. Duramed
will have sole discretion over establishing the price at which it sells the
product to

                                       F-7

customers 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 income tax return and no Federal
income tax was imposed on the

                                       F-8

<PAGE>   68



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:

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 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.

10.  COMMITMENTS AND CONTINGENCIES

OPERATING LEASES - The Company is obligated under a non-cancelable operating
lease agreement for the rental of its facility which expires in May 2000. The
lease agreement provides that the Company pay its proportionate share of
building maintenance, real estate taxes and similar items. At December 31, 1995
minimum annual rentals are as follows:

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
compensation under such agreements at December 31,1995 is approximately as
follows:

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 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.

                                      F-14

<PAGE>   74



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.

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 generic drugs.

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. It is the
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>   82



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

Property and equipment is stated at cost and consisted of the following at
December 31, 1994 and 1993:

approximately $31,871 (including interest) through June 1999. Substantially all
of the Company's assets are pledged as collateral to the note payable. Also,
such note is personally guaranteed by certain of the Company's stockholders.

Long-term debt maturing in each of the years ended December 31, 1994 is as
follows:

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

The Company leases equipment from a partnership in which the partners are also
stockholders of the Company. These leases expire during 1997, 1998 and 1999 and
are accounted for as capital leases as a result of certain provisions in the
lease agreements. Future minimum lease payments, by year and in the aggregate,
and the present value of the future minimum lease payments at December 31, 1994
are as follows:

aggregated $18,753 and $19,298, respectively, and is included in the balance
sheet caption "Interest payable to stockholders".

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

                                      F-25

<PAGE>   85



of the shares at the time of issuance.  Such amounts aggregated
$150,000 and $202,000 during 1994 and 1993, respectively.

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

                                      F-26

<PAGE>   86



are not more likely than not. The Company's deferred tax benefits were generated
principally as a result of such losses.

9.       COMMITMENTS

Operating leases - The Company is obligated under two non-cancelable operating
lease agreements for the rental of its facilities which expire in July 1999 and
May 2000. The lease agreements provide that the Company pay its proportionate
share of building maintenance, real estate taxes and similar items. At December
31, 1994 minimum annual rentals are as follows:

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 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
assist the Company in raising additional expansion capital of approximately $ 15
million dollars. In connection with such agreement, the Company is obligated to
pay this entity a minimum of $75,000 (increased to $350,000 under certain
circumstances) and a maximum of approximately $1,000,000, depending upon the
amount of financing.

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 capital 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 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.

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

providing for the distribution to its shareholders of all of its assets (after
payment of liabilities and expenses), including proceeds to be realized from the
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 August 2, 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

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.

                  6. The officers and directors of the Corporation shall do and
perform all acts, execute all documents, file all reports, statements,
certificates and returns, take all action and enter into all transactions in the
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.

                  7. The Plan shall become effective on the date of its

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
Common Stock during the ninety (90) day period immediately preceding the day on
which such

                                      B-8
<PAGE>   109
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
8.1 hereof (a "Claim"), (ii) specifying the estimated amount of such Claim and
the calculation of such amount, and (iii) setting forth in reasonable detail the
grounds for such Claim. Duramed shall be entitled to indemnification hereunder
from the Escrow Fund only if and to the extent that its valid Claims exceed an
aggregate of $100,000.

         (b) Before the twentieth business day after receipt of any Claim Notice
from Duramed, the Company shall notify Duramed that it either agrees with the
Claim and directs the Escrow Agent to pay it or that it disputes the existence
of such Claim or objects to Duramed's calculation of the amount of such Claim (a
"Notice of Dispute"). Any Notice of Dispute shall set forth in

                                      B-9
<PAGE>   110
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
it shall be deemed to have given a Notice of Dispute as to the entire Claim.

         (c) If Duramed receives, or is deemed to have received, a Notice of
Dispute before the close of the twentieth business day referred to in Section
1.5(b) above, Duramed and the Company shall negotiate in good faith and use all
reasonable efforts to agree, within twenty (20) business days after Duramed's
receipt of the Notice of Dispute, upon the rights of the respective parties with
respect to such Claim. If Duramed and the Company shall so agree, a certificate
setting forth such agreement (including the amount, if any, due Duramed with
respect to any Claim referred to therein) shall be furnished to the Escrow
Agent. The Escrow Agent shall be entitled to rely on any such certificate and
shall promptly make payment to Duramed from the Escrow Fund in accordance with
the terms thereof.

         (d) If after the expiration of the twenty (20) business day negotiation
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
Duramed.

         Section 1.6                Termination of Escrow.

         (a) On the date twelve (12) months after the Closing Date, the Company
and Duramed shall instruct the Escrow Agent to deliver the Escrow Fund (less an
amount equal to the amount claimed pursuant to claims of Duramed then determined
to be payable, or which are still pending final determination, pursuant to the
Escrow Agreement) to the Company or its designees.

         (b) In making the distributions described in Section 1.6(a) hereof,
neither the Escrow Agent nor Duramed shall be obligated to deliver any
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
cash equivalent of the Market Price of such fractional share on the date of
distribution.

Stock, Warrants or dividends on such Duramed Common Stock delivered to a public
official pursuant to applicable abandoned property, escheat or similar laws.

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

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

except, in the case of the preceding clauses (a), (b)(i)(A) through (b)(i)(D),

Disclosure Schedule sets forth a complete list of all Intellectual Property
rights owned by the Company which are material to the Condition of the Company.
Except to the extent that the inaccuracy of any of the following (or the

                    REPRESENTATIONS AND WARRANTIES OF DURAMED

duly incorporated and organized, validly existing and in good standing under the
laws of the State of Delaware. All of the Duramed Subsidiaries are corporations
duly incorporated and organized, validly existing and in good standing (or their
status is active) under the laws of their jurisdictions of incorporation.
Duramed and the Duramed Subsidiaries have the requisite corporate power to
conduct their businesses as they are currently being conducted and are duly
qualified as foreign corporations to do business in the respective jurisdictions
where the character of their properties owned or leased or the nature of their
activities makes such qualification necessary, except to the extent that lack of
such qualification would not have a material adverse effect on the Condition of
Duramed and the Duramed Subsidiaries taken as a whole.

         Section 4.2 Capitalization. The authorized capital stock of Duramed
consists of Fifty Million shares of Duramed Common Stock, par value $.01 per

share ("Duramed Preferred Stock"), of which One Hundred Thousand (100,000)
shares have been designated as Series A Preferred Stock, Seventy-Four Thousand
Six Hundred Fifty-Nine (74,659) shares have been designated as Series B

Thousand, Five Hundred Twenty-Nine (32,529) shares of Series B Non-Voting

in treasury. All of the issued and outstanding shares of capital stock of
Duramed are validly issued, fully paid and nonassessable and are not subject to,
nor were they issued in violation of, any preemptive rights. The parties
acknowledge that Duramed may from time to time from the date of execution hereof
until the Closing Date issue shares of one or more classes of its capital stock,
and that nothing in this Agreement shall restrict Duramed's rights to so issue
stock. All of the outstanding shares of capital stock of each of the Duramed
Subsidiaries have been validly issued and are fully paid and nonassessable and
are beneficially owned by either Duramed or one of the Duramed Subsidiaries free
and clear of all liens, charges, claims or encumbrances. Except as set forth
herein or in Section 4.2 of the Duramed Disclosure Schedule, there are no
outstanding subscriptions, options, warrants, calls, rights, convertible
securities or other agreements or commitments of any character relating to the
issued or unissued capital stock of any of the Duramed Subsidiaries or
securities convertible into, exchangeable for or evidencing the right to
subscribe for any shares of such capital stock, or otherwise obligating any such
subsidiary to issue, transfer or sell any such capital stock or other
securities. Except as set forth in Section 4.2 of the Duramed Disclosure
Schedule, there are no voting trusts or other agreements or understandings to
which Duramed is a party with respect to the voting of the capital stock of
Duramed. All shares of Duramed Common Stock issued pursuant to the terms of this
Agreement will be duly authorized, fully paid and nonassessable and not subject
to or issued in violation of any preemptive rights.

         Section 4.3 Authority Relative to this Agreement. Duramed has the
requisite corporate power and authority to execute and deliver this Agreement
and to consummate the transactions contemplated hereby. The execution and
delivery of this Agreement and the consummation of the transactions contemplated
hereby have been duly authorized by the Board of Directors of Duramed and no
other corporate proceedings on the part of Duramed are necessary to authorize
this Agreement and the transactions contemplated hereby. This Agreement has been
duly and validly executed and delivered by Duramed and (assuming this Agreement
is a valid and binding obligation of the other parties hereto) constitutes a
valid and binding agreement of Duramed enforceable against Duramed in accordance
with its terms, except that (i) such enforcement may be subject to bankruptcy,
insolvency, reorganization, moratorium, fraudulent transfer or other similar
laws now or hereafter in effect relating to

                                     B-30
<PAGE>   131
creditors' rights generally and (ii) the remedy of specific performance and
injunctive and 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.

         Section 4.4 No Violation. Except as set forth in Section 4.4 of the
Duramed 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
Incorporation or the By-laws of Duramed or any of the Duramed Subsidiaries or
(ii) violate, conflict with, or result in a breach of any provisions of, or
constitute a default (or an event which, with notice or lapse of time or both,
would constitute a default) under, or result in the termination of, or
accelerate the performance required by, or result in a right of termination or
acceleration under, or result in the creation of any lien, security interest,
charge or encumbrance upon any of the properties or assets of Duramed or any of
the Duramed Subsidiaries under any of the terms, conditions or provisions of any
credit agreement, note, bond, mortgage, indenture, deed of trust, license,
lease, agreement or other instrument or obligation to which Duramed or any of
the Duramed Subsidiaries is a party or to which they or any of their respective
properties or assets may be subject, other than, in the case of clause (ii),
breaches, conflicts or violations that would not have a material adverse effect
on the Condition of Duramed and the Duramed Subsidiaries taken as a whole.
Except as set forth in Section 4.4 of the Duramed Disclosure Schedule, (i) other
than in connection with, or in compliance with, the provisions of the DGCL, the
New Jersey Business Corporation Act, the Securities Act (as applicable to the
registration of Duramed Common Stock and Warrants pursuant to Section 2.3
hereof), the Exchange Act and any applicable state securities laws, the
consummation by Duramed of the transactions contemplated hereby will not require
the consent or approval of any other party to any of the above or affect the
validity or effectiveness of any of the above except for consents or approvals,
the failure to obtain which would not, in the aggregate, have a material adverse
effect on the Condition of Duramed and the Duramed Subsidiaries taken as a whole
and (ii) the execution, delivery and performance by Duramed of this Agreement
and the consummation by Duramed of the transactions contemplated hereby will not
constitute a breach or violation of or default under any law, rule or regulation
or any judgment, decree, order, governmental permit or license to which Duramed
or any of the Duramed Subsidiaries is subject. Neither Duramed nor any of the
Duramed Subsidiaries is subject to, or a party to, any charter, bylaw, mortgage,
lien, lease, license, permit, agreement, contract, instrument, law, rule,
ordinance, regulation, order, judgment or decree, or other restriction of any
kind or character, that materially adversely affects the business practices,
operations or Condition of Duramed or any of its assets or property (other than
such items generally affecting

                                     B-31
<PAGE>   132
the industry in which Duramed or any of the Duramed Subsidiaries operate) or
that would prevent the continued operation of Duramed's or any of the Duramed
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>   133
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>   134
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>   135
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>   136
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

<PAGE>   143
                  (a) Duramed shall have performed and complied in all material

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

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>   144
                           (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

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.

Duramed to conclude the transactions described herein shall be subject to the
fulfillment at or prior to the

nonassignable or which require consent to assignment and (iv) to assign to

                           (2) The Company has the corporate power and corporate

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

                                     B-45
<PAGE>   146
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

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

state securities laws, consent, approval or authorization of, or notice to, or

                           (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.

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>   148
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. Section 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.

                                   TERMINATION

         Section 7.1 Termination. This Agreement may be terminated and the
transactions contemplated hereby abandoned at any time prior to the Closing,
whether before or after approval of the transactions contemplated hereby by the
shareholders of the Company:

                  (a)      by mutual consent of Duramed and the Company;


                                     B-48
<PAGE>   149
                  (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
this Agreement. The repurchase described in this Section 7.3 shall occur, if at
all, within ninety (90) days of the final termination of this Agreement.

(collectively "Damages") arising from or in connection with any inaccuracy in
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
actions, omissions or state of facts inconsistent with any such representation
or warranty of the Company, or any Excluded Liabilities. After the Closing, and
for a period of one (1) year, Duramed may assert any such Damages against the
Duramed Common Stock and Warrants held in the Escrow Fund in accordance with
Section 1.5 hereof, but shall not

                                     B-50
<PAGE>   151
otherwise assert any such claim against the Company or its shareholders.

                  (b) Duramed shall indemnify and hold harmless the Company and
its shareholders, and shall reimburse them for, any Damages arising from or in
connection with any inaccuracy in any of the representations and warranties of
Duramed in this Agreement, or in any certificate delivered by Duramed pursuant

assumed by Duramed pursuant to Section 1.3 hereof, or the conduct of the
Business by Duramed after the Closing.

the breach or violation of any warranty or representation set forth herein shall
terminate one (1) year after the Closing, except that any claim for

prior to such date shall extend the survival period until final determination of
such claim. The parties hereto agree that liability of Duramed to any party,
including the Company or its shareholders as in existence immediately prior to
the Closing (or those claiming through them), for the breach or violation of any
warranty or representation set forth herein shall terminate one (1) year after
the Closing, except that any claim for indemnification by the Company or its

14A:5-5(1)                   Any notice required by these by-laws, by the

                             the event with respect to which notice is waived. For each director
                             or shareholder attending a meeting without protesting, prior to its
                             conclusion, the lack of proper notice shall be deemed conclusively to
                             have waived notice of the meeting.

                             by the Board, unless the resolution of the shareholders adopting
                             such by-law expressly reserves to the shareholders the right to
                             amend or repeal it.

                       4.    FISCAL YEAR.  The fiscal year of the Corporation shall begin on the

                     INFORMATION NOT REQUIRED IN PROSPECTUS

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.

                                                                    EXHIBIT 4.5
                          DURAMED PHARMACEUTICALS, INC.


               WARRANT FOR THE PURCHASE OF SHARES OF COMMON STOCK



No. WH-1                                                         400,000 Shares


         FOR VALUE RECEIVED, DURAMED PHARMACEUTICALS, INC. (the "Corporation"),
a Delaware corporation, hereby certifies that HALLMARK PHARMACEUTICALS, INC., a
New Jersey Corporation ("Hallmark") or its permitted assignee is entitled to
purchase from the Corporation, from and after the date hereof and on or before
___________________, 2001 (the "Termination Date")[insert the fifth anniversary
of the Closing Date], Four Hundred Thousand (400,000) fully paid and
non-assessable shares of the Common Stock, $.01 par value per share, of the
Corporation, for a purchase price of Twenty Five Dollars ($25.00) per share.
Hereinafter, (i) said common stock, together with any other equity securities
which may be issued by the Corporation in addition thereto or in substitution
therefor, is referred to as "Common Stock", (ii) the shares of Common Stock
purchasable hereunder are referred to as the "Warrant Shares", (iii) the
aggregate purchase price payable hereunder for the Warrant Shares is referred to
as the "Aggregate Warrant Price" and (iv) the price payable hereunder for each
of the Warrant Shares is referred to as the "Per Share Warrant Price". The Per
Share Warrant Price and the number of Warrant Shares are subject to adjustment
as hereinafter provided. As used herein, 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 commencing 12 trading days before the date
in question. "Closing price" on any day when used with respect to the Common
Stock means the reported closing price therefor as reported by Bloomberg, L.P.,
or if not so reported the average of the closing bid and asked prices as
furnished by any member of the National Association of Securities Dealers, Inc.
selected from time to time by the Corporation for that purpose.

         1.    EXERCISE OF WARRANT. This Warrant may be exercised in whole or in
part on or after first anniversary hereof and on or before the Termination Date
by the Holder (as defined in Section 5 below) of this Warrant (provided that
this Warrant may not be exercised for more than one-third of the Warrrant Shares
prior to


<PAGE>   2



___________, 1998 [insert the second anniversary of the Closing Date]; or more
than two-thirds of the Warrant Shares prior to _____________, 1999 [insert the
third anniversary of the Closing Date], by the surrender of this Warrant (with
the subscription form at the end hereof duly executed) at the principal office
of the Corporation, together with payment of the Aggregate Warrant Price for the
Warrant Shares being purchased. Payment for Warrant Shares shall be made by
check payable to the order of the Corporation, or the Holder may direct that a
portion of the shares to be issued upon exercise of the Warrant be withheld by
the Corporation as payment, to the extent permitted by law. Any such shares
withheld shall be valued for such purpose at the Market Price on the date of
issuance. Upon such surrender of this Warrant the Corporation will issue a
certificate or certificates in the name of the Holder for the largest number of
whole shares of Common Stock to which the Holder shall be entitled and, in lieu
of any fractional share of Common Stock to which the Holder shall be entitled,
cash equal to the fair value of such fractional share (determined in such manner
as the Board of Directors of the Corporation shall reasonably determine).

         2.     RESERVATION OF WARRANT SHARES. The Corporation will at all times
reserve and keep available, solely for issuance or delivery upon the exercise of
this Warrant, the shares of Common Stock and Other Securities (as defined below)
receivable upon the exercise of this Warrant, free and clear of all restrictions
on sale or transfer and free and clear of all pre-emptive rights.

         3.     FULLY PAID STOCK; TAXES. The Corporation agrees that the 
Shares of Common Stock represented by each and every certificate for Warrant
Shares or Other Securities delivered on the exercise of this Warrant shall, at
the time of such delivery, be validly issued and outstanding, fully paid
and non-assessable, and the Corporation will take all such action as may be
necessary to assure that the par value or stated value per share of Common
Stock or other capital stock included in the Other Securities is at all times
equal to or less than the then Per Share Warrant Price. The Corporation further
covenants and agrees that it will pay, when due and payable, all federal and
state stamp, original issue or similar taxes, if any, which are payable in
respect of the issue of this Warrant and/or any Warrant Share or certificates
therefor but excluding any federal, state or local taxes based on the income of
the Holder.

         4.     ADJUSTMENTS OF PER SHARE WARRANT PRICE. (a) If at any time 
after the date hereof shares of Common Stock are issued as a dividend or other  
distribution on Common Stock, the Per Share Warrant Price in effect at the
opening of business on the business day next succeeding the date fixed for the
determination of the shareholders entitled to receive such dividend or other
distribution shall be decreased to the Per Share Warrant Price determined by
multiplying said Per Share Warrant Price so in

                                      - 2 -

<PAGE>   3



effect by a fraction, the numerator of which shall be the number of shares of
Common Stock issued and outstanding at the close of business on the date fixed
for such determination and the denominator of which shall be the sum of said
number of shares issued and outstanding at the close of business on the date
fixed for such determination and the number of shares constituting such dividend
or other distribution, such decrease becoming effective immediately after the
opening of business on the business day next succeeding the date fixed for such
determination.

         (b) If at any time after the date hereof the outstanding shares of
Common Stock shall be subdivided into a greater number of shares or outstanding
shares shall be combined into a smaller number of shares, the per Share Warrant
Price in effect at the opening of business on the business day next succeeding
the day upon which such subdivision or combination becomes effective shall be
decreased or increased, as the case may be, to the Per Share Warrant Price
determined by multiplying said Per Share Warrant Price so in effect by a
fraction, the numerator of which shall be the number of shares of Common Stock
outstanding immediately before such subdivision or combination becomes effective
and the denominator of which shall be the number of such shares outstanding at
the opening of business on the business day next succeeding the day upon which
such subdivision or combination becomes effective.

         (c) If at any time after the date hereof the Corporation shall issue
shares of Common Stock (other than pursuant to any right to purchase such shares
in existence as of the date hereof or pursuant to any stock option plan for
employees or directors of the Corporation) or securities convertible into shares
of Common Stock or rights, options (other than pursuant to any right to purchase
such shares in existence as of the date hereof or pursuant to any stock option
plan for employees or directors of the Corporation) or warrants (other than this
Warrant) containing the right to subscribe for or purchase shares of Common
Stock or securities convertible into shares of Common Stock for a price per
share of Common Stock, in the case of the issuance of Common Stock, or for a
price per share of Common Stock initially deliverable upon conversion, exchange
or exercise of such convertible securities or rights, options or warrants
(including all consideration paid to acquire such convertible securities or
rights, options or warrants) (the "Issue Price"), less than the lesser of the
then current Per Share Warrant Price and the Market Price of the Common Stock,
each on the date the Corporation fixed the offering, conversion, exchange or
exercise price of such shares (the "Record Date"), then the then applicable Per
Share Warrant Price shall be adjusted by multiplying it by a fraction, the
numerator of which is the number of shares of Common Stock outstanding
immediately prior to the Record Date plus the number derived by dividing (x) the
product of the number of shares of Common Stock to be issued upon such offering,
conversion,

                                      - 3 -

<PAGE>   4



exchange or exercise and the Issue Price by (y) the then current Per Share
Warrant Price or Market Price, as the case may be, and the denominator of which
is the number of shares of Common Stock outstanding immediately prior to the
Record Date plus the number of shares of Common Stock to be issued upon such
offering, conversion, exchange or exercise. Such adjustment shall be made
whenever such shares, convertible securities, rights, options or warrants are
issued, and shall become effective immediately after the effective date of such
event retroactive to the Record Date, if any, for such event.

         (d) If at any time after the date hereof the Corporation shall
distribute to all or substantially all holders of Common Stock either (i)
evidences of indebtedness or assets (excluding cash dividends or distributions)
or (ii) any other securities of the Corporation or any rights, warrants, options
to subscribe for, purchase or otherwise acquire securities of the Corporation in
a transaction not covered by paragraph (c) 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 Holder of this Warrant or reserve
for the benefit of the Holder of this Warrant such amount of such Other
Securities as the Holder of this Warrant would have owned or been entitled to
receive immediately following such action had this Warrant been exercised for
shares of Common Stock immediately prior thereto. In addition, the Corporation
shall either distribute to, or reserve for the benefit of, the Holder of this
Warrant 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 this Warrant is exercised, the Holder shall be entitled to
receive from the Corporation such Holder's share of such Other Securities
together with the principal, interest, dividends or other property payable with
respect thereto.

         (e) Upon each adjustment of the Per Share Warrant price pursuant to
this Section 4, the Holder of this Warrant shall thereafter (until another such
adjustment) be entitled to purchase, at the adjusted Per Share Warrant Price
applicable at the date purchase rights hereunder are exercised, the number of
shares of Common Stock, calculated to the nearest full share, obtained by:

                  (i) multiplying (A) the number of Warrant Shares deliverable
         upon exercise of such Warrant at the close of business on the business
         day next preceding the business day on which the Per Share Warrant
         Price is so adjusted by (B) the Per Share Warrant Price in effect at
         the close of business on such next preceding business day; and


                                      - 4 -

<PAGE>   5



                  (ii) by dividing (C) the Per Share Warrant Price as adjusted
         into (D) the amount determined pursuant to the foregoing clause (e)(i).

Irrespective of any adjustment in the Per Share Warrant Price and the number of
Warrant Shares purchasable under this Warrant, any Warrant thereafter issued
shall continue to express the Per Share Warrant Price and the number of shares
purchasable in the same manner as the Per Share Warrant Price and the number of
shares purchasable were expressed in this Warrant when initially issued.

         (f) Upon any adjustment of the Per Share Warrant Price and/or an
increase or decrease in the number of Warrant Shares purchasable upon the
exercise of this Warrant, then, and in each such case, the Corporation will
promptly obtain a certificate of a firm of independent public accountants of
recognized national standing selected by its Board of Directors (who may be the
regular auditors of the Corporation) setting forth the adjusted Per Share
Warrant Price and the increased or decreased number of Warrant Shares
purchasable upon the exercise of this Warrant, a brief statement of the facts
accounting for such adjustment and its opinion to the effect that such
adjustment has been made in accordance with the provisions of this Section 4.
Upon receipt of such option, the Corporation will promptly mail a copy thereof
to the Holder of this Warrant.

         (g) If, on or prior to the Termination Date, the Corporation shall
consolidate with or merge into another corporation, or another corporation shall
merge into the Corporation in a merger in which shares of Common Stock are
converted into a right to receive cash, property or other securities, or the
Corporation shall sell or transfer all or substantially all of the assets of the
Corporation, or there shall be any reclassification of Common Stock of the
Corporation, other than a subdivision or combination of the outstanding Common
Stock, the Corporation shall take such action so that the Holder of this Warrant
will thereafter receive upon the exercise hereof the securities or property to
which a holder of the number of shares of Common Stock then deliverable upon the
exercise of such Warrant would have been entitled to receive upon such
consolidation, merger, sale, transfer or reclassification if such Warrant had
been exercised in full immediately prior to such transaction.

         (h) All calculations under this Section 4 shall be made to the nearest
one-hundredth 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 (1%) percent of the Per Share Warrant
Price; provided, however, that any adjustments which by reason of this paragraph
(h) are not required to be made shall be carried forward and taken into account
in any subsequent adjustment.

                                      - 5 -

<PAGE>   6




         (i) If at any time, as a result of an adjustment made pursuant to
paragraph (d) above, the Holder shall become entitled to purchase any Other
Securities, thereafter the number of such Other Securities purchasable upon
exercise of this Warrant 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 this Warrant
contained in paragraphs (a) through (h), inclusive above.

         (j) Upon the expiration of any rights, options, warrants or conversion
of exchange privileges which caused an adjustment to the Per Share Warrant Price
to be made, if any thereof shall not have been exercised, the Per Share Warrant
Price shall, upon such expiration, be readjusted and shall thereafter be such as
it would have been had it been originally adjusted (or had the original
adjustment not been required, as the case may be) as if (i) the only shares of
Common Stock so issued were the shares of Common Stock, if any, actually issued
or sold upon the exercise of such rights, options, warrants or conversion or
exchange privileges and (ii) such shares of Common Stock, if any, were issued or
sold for the consideration actually received by the Corporation upon such
exercise plus the aggregate consideration, if any, actually received by the
Corporation for the issuance, sale or grant of all such rights, options,
warrants or conversion or exchange privileges, whether or not exercised;
provided further, that no such readjustment shall have the effect of decreasing
the Per Share Warrant Price by an amount in excess of the amount of the
adjustment initially made in respect to the issuance, sale or grant of such
rights, options, warrants or conversion or exchange privileges.

         (k) Upon any exercise of this Warrant at a time when there are
dividends or distributions unpaid (whether as to Common Stock or Other
Securities or other property payable with respect hereto) and as to which the
dividend date or other date fixed for payment has passed, then, (i) to the
fullest extent permitted by law, such unpaid dividends or distributions shall be
paid by the Corporation contemporaneously with the exercise of this Warrant, and
(ii) to the extent payment of such unpaid dividends or distributions is not
legally permitted, then the Per Share Warrant Price shall be further adjusted by
increasing the number of shares of Common Stock or Other Securities or property
issuable upon conversion to take into account the value of such unpaid dividends
or other distributions in determining the amount of Common Stock or Other
Securities to be issued upon exercise of this Warrant.

         5.       TRANSFER.  (a) This Warrant is transferable only upon
the books which the Corporation shall cause to be maintained for
such purpose.  Any assignment or transfer may be made by
surrendering this Warrant to the Corporation together with the
attached assignment form properly executed by the assignor or

                                      - 6 -

<PAGE>   7



transferor. Upon such surrender the Corporation will execute and deliver, in the
case of an assignment or transfer in whole, a new Warrant in the name of the
assignee or transferee or, in the case of an assignment or transfer in part, a
new Warrant in the name of the assignee or transferee named in such instrument
of assignment or transfer and a new Warrant in the name of the assignor or
transferor covering the number of Warrant Shares in respect of which this
Warrant shall not be assigned or transferred to the assignee or transferee.

         (b) The Corporation may treat the registered holder of this Warrant
(the "Holder") as it appears on its books at any time as the owner of this
Warrant for all purposes. The Corporation shall permit the Holder of this
Warrant or his duly authorized attorney, upon written request during ordinary
business hours, to inspect and copy or make extracts from its books showing the
Holders of Warrants. All Warrants will be dated the same date as this Warrant.

         6.       NOTICES TO HOLDER.  If at any time,

                  (a) the Corporation shall take any action which would require
an adjustment in the Per Share Warrant Price or in the number of shares issuable
upon exercise of this Warrant; or

                  (b)  the Corporation shall authorize the making to the
holders of its Common Stock of any non-cash distribution on such
Common Stock; or

                  (c)  the Corporation shall declare any dividend (or any
other distribution) on its Common Stock; or

                  (d) there shall be any capital reorganization or
reclassification of the Common Stock, or any consolidation or merger to which
the Corporation is a party, or any sale or transfer of all or substantially all
of the assets of the Corporation; or

                  (e)  there shall be a voluntary or involuntary
dissolution, liquidation or winding-up of the Corporation;

then, in any one or more of such cases, the Corporation shall give written
notice to the Holder, not less than ten (10) days before any record date or
other date set for definitive action, or of the date on which such
reorganization, reclassification, sale, consolidation, merger, dissolution,
liquidation or winding up shall take place, as the case may be. Such notice
shall also set forth such facts as shall indicate the effect of such action (to
the extent such effect may be known at the date of such notice) on the current
Per Share Warrant Price and the kind and amount of shares of Common Stock and
other securities and property deliverable upon exercise of this Warrant. Such
notice

                                      - 7 -

<PAGE>   8



shall also specify the date as of which the holders of the Common Stock of
record shall be entitled to exchange their shares of Common Stock for securities
or other property deliverable upon such reorganization, reclassification, sale,
consolidation, merger, dissolution, liquidation or winding up, as the case may
be. Notwithstanding the foregoing, failure to give such notice shall not affect
the validity of any such action.

         7.       LOSS, ETC. OF WARRANT. Upon receipt of evidence satisfactory 
to the Corporation of the loss, theft, destruction or mutilation of this
Warrant, and of indemnity in form and amount reasonably satisfactory to the
Corporation, if lost, stolen or destroyed, and upon surrender and cancellation
of this Warrant, if mutilated, and upon reimbursement of the Corporation's
reasonable incidental expenses, the Corporation shall execute and deliver to
the Holder a new Warrant of like date, tenor and denomination.

         8.       WARRANT HOLDER NOT A SHAREHOLDER.  This Warrant does not 
confer upon the Holder any rights or liabilities as a shareholder prior to the
exercise hereof.

         9.       COMMUNICATION.  No notice or other communication under this 
Warrant shall be effective unless, but any notice or other communication shall
be effective and shall be deemed to have been given if, the same is in writing
and is mailed by first-class mail, postage prepaid, addressed to

                  (a) the Corporation at 7155 East Kemper Road, Cincinnati, 
         OH 45249, or such other address as the Corporation has designated in 
         writing to the Holder, or

                  (b) the Holder at 400 Campus Drive, Somerset, New Jersey 08873
         or such other address as the Holder has designated in writing to the
         Corporation.

         10.      HEADINGS.  The headings of this Warrant have been inserted as 
a matter of convenience, and shall not affect the construction hereof.

         11.      AMENDMENTS.  This Warrant may be amended only by written 
agreement of the Corporation and the Holder.

         12.      APPLICABLE LAW.  This Warrant shall be governed by and
construed in accordance with the laws of the State of Delaware
applicable to agreements made and to be performed therein.

Dear Sir or Madam:

         We have acted as counsel for Duramed Pharmaceuticals, Inc. (the
"Company") in connection with its filing of a Registration Statement on Form S-4
concerning the registration of 640,000 shares of common stock, $.01 par value,
and Warrants to purchase 400,000 shares of common stock (including the common
stock to be issued upon exercise of such Warrants, collectively the
"Securities") to be issued by Duramed in connection with its purchase of
substantially all of the assets of Hallmark Pharmaceuticals, Inc.

         It is our opinion that the registration of the Securities covered by
the Registration Statement and the issuance of such Securities have been duly
authorized by all necessary corporate action by the Company. The Securities will
be, when issued in accordance with the terms and conditions of the agreements
providing for their issuance, legally issued and, in the case of the securities
constituting common stock, fully paid and non-assessable.

         We hereby consent to the filing of this opinion as an Exhibit to the
aforesaid Registration Statement and to the reference to our firm under the
caption "Legal Matters" in the Prospectus/Proxy Statement.

                                              Yours very truly,


                                              /s/ Taft, Stettinius & Hollister

                                ESCROW AGREEMENT


                  THIS AGREEMENT made this _____ day of ______________, 1996, by
and among DURAMED PHARMACEUTICALS, INC., a Delaware corporation ("Duramed"),
HALLMARK PHARMACEUTICALS, INC. ("Hallmark") (Hallmark and Duramed are
collectively referred to herein as the "Parties"), and THE PROVIDENT BANK (the
"Escrow Agent").

                  Pursuant to a certain Asset Purchase Agreement dated as of
April 9, 1996 (the "Asset Purchase Agreement") between Duramed and Hallmark
Pharmaceuticals, Inc., at the Closing (as defined in the Asset Purchase
Agreement), Duramed shall issue 640,000 shares of common stock, par value $.01
per share, of Duramed ("Duramed Common Stock") and Warrants to purchase 400,000
shares of Duramed Common Stock (the "Warrants") in exchange for substantially
all the assets of Hallmark. Pursuant to the Asset Purchase Agreement, Ten
Percent (10%) of the aggregate number of shares of Duramed Common Stock and
Warrants to be issued thereunder will be placed in an escrow account pending
expiration of Hallmark's indemnification obligations to Duramed. The Escrow
Agent has agreed to act as the escrow agent hereunder.

                  The parties agree as follows:

                  SECTION 1. ESCROW AMOUNT. Duramed agrees to deposit with the
Escrow Agent on or before the date of closing under the Asset Purchase Agreement
(the "Closing Date") that number of shares of Duramed Common Stock and Warrants
equal to Ten Percent (10%) of the shares of Duramed Common Stock and Warrants to
be issued to Hallmark pursuant to the Asset Purchase Agreement (the "Escrow
Fund"), to be paid by the Escrow Agent to Duramed and/or Hallmark or its
designees as appropriate in accordance with the procedures outlined in Section 2
below.

                  SECTION 2. RELEASE OF ESCROW FUND. (a) The Escrow Agent shall
promptly tender all or any portion of the Escrow Fund as specified in and upon a
written instruction from both Hallmark and Duramed.

                           (b)      The Escrow Fund shall secure Hallmark's
obligations to Duramed under Section 8.1 of the Asset Purchase
Agreement.

                                    (i) The Escrow Agent shall hold the Escrow
                           Fund until instructed to transfer or pay all or any
                           portion thereof to Duramed by written instructions
                           signed by both Duramed and Hallmark or by an
                           arbitrator as provided below. If any claim by Duramed
                           shall be disputed by Hallmark, the Parties shall
                           appoint an arbitrator to hear


<PAGE>   2



                           the claim under the rules of the American Arbitration
                           Association. The decision of the arbitrator so
                           appointed shall be conclusive and binding upon
                           Duramed and Hallmark and the Escrow Agent shall be
                           entitled to rely on such decision and make payment
                           out of the Escrow Fund in accordance therewith.

                                    (ii) If, as of the date one (1) year after
                           the date of this Agreement (the "Termination Date"),
                           Duramed has not asserted any claims under the Asset
                           Purchase Agreement (or if all such claims asserted
                           prior to such date have been finally resolved on or
                           before such date and all payments required to be made
                           to Duramed from the Escrow Fund under the terms of
                           this Agreement have been made) then the Parties shall
                           instruct the Escrow Agent to transfer any remaining
                           portion of the Escrow Fund to Hallmark. Such transfer
                           shall not limit or modify the rights of Duramed under
                           the Asset Purchase Agreement.

                                    (iii) If as of the Termination Date claims
                           have been asserted but are unresolved ("Contingent
                           Claims"), the parties shall instruct the Escrow Agent
                           to hold a portion of the Escrow Fund consisting of
                           cash and/or a number of shares of Duramed Common
                           Stock and/or Warrants with an aggregate value
                           (computed as provided below) equal to the amount of
                           the Contingent Claims (the "Contingent Amount") until
                           resolution of such Contingent Claims and, as such
                           Contingent Claims are resolved, the Escrow Agent
                           shall release the Contingent Amount in accordance
                           with paragraphs (i) or (ii) above, as applicable.

                           (c)      The Escrow Agent shall, upon receipt of 
authorization to pay any claim from assets then held in the Escrow Fund, pay
such claim out of the cash or Investment Securities (as hereinafter defined),
Shares of Duramed Common Stock and Warrants then held in the Escrow Fund
in such order of priority as Hallmark shall instruct the Escrow Agent in
writing.

                           (d)      The number of shares of Duramed Common Stock
to be released to Duramed pursuant to a valid claim or held by the Escrow Agent
pursuant to Contingent Claims shall be determined based on the average Market
Price of Duramed Common Stock during the ninety (90) day period immediately
preceding the day on which such payment to Duramed is made, or the Termination
Date, as appropriate. The number of Warrants to be released to Duramed pursuant
to a valid Claim or held by the Escrow Agent pursuant to Contingent Claims shall
be determined based on the fair market value of such Warrants on the day on
which such

                                      - 2 -

<PAGE>   3



payment to Duramed is made, or the Termination Date, as appropriate, in either
case as reasonably determined by an independent third party experienced in
valuing such securities to be selected jointly by the Parties. For purposes of
this Agreement, "Market Price" shall mean the closing price for Duramed Common
Stock quoted on The Nasdaq Stock Market, or if there is no closing price for a
particular date, the average of the bid and asked prices for such date, or if
such prices are not reported, such amount as may be determined by an independent
third party to be selected jointly by the Parties.


                  SECTION 3.  SERVICES OF ESCROW AGENT.
                                  
                           (a)     The Escrow Agent shall hold the Escrow Fund
and shall collect any dividends or distributions which may be made from time to
time with respect to the shares of Duramed Common Stock then held in the Escrow
Fund and, after deducting all proper charges and expenses, shall accumulate said
dividends or distributions and add the same to the Escrow Fund.
                   
                           (b)     During the term of the Escrow Agreement, 
Hallmark shall have the right to direct the Escrow Agent in writing to sell all
or any portion of the Shares of Duramed Common Stock and/or Warrants then held
in the Escrow Fund. Upon receipt of such direction, the Escrow Agent shall
promptly effect such sale by offering such shares and/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 2 hereof or
until the termination of this Agreement.

                           (c)     During the term of the Escrow Agreement, 
Hallmark shall have the right to direct the Escrow Agent in writing to vote the
Shares of Duramed Common Stock then held in the Escrow Fund in any matter in
which such Shares are entitled to vote. Upon receipt of such written direction,
the Escrow Agent shall take such action, including but not limited to the
execution of appropriate proxies, as shall be necessary to effect such vote.

                  SECTION 4. COMPANY REPRESENTATIVE. The parties acknowledge
that Hallmark may choose to liquidate its remaining assets and terminate its
corporate existence at or shortly after the Closing and during the term of this
Agreement. In such event, Vish Raju, or such other person as the Company may
appoint pursuant to the Asset Purchase Agreement (the "Company Representative")
shall represent the interests of Hallmark and persons whose interests arise
through or from Hallmark in all matters related to this Agreement. Upon
termination of Hallmark's corporate existence, all references to Hallmark herein

                                      - 3 -

<PAGE>   4



shall be deemed to refer to the Company Representative, unless another
interpretation is clearly required.

                  SECTION 5. INVESTMENT OF ESCROW FUND. Investment of any cash
portion of the Escrow Fund shall be limited to (i) commercial paper that has the
highest credit rating of either Standard & Poor's Corporation or Moody's
Investor Service, Inc., (ii) certificates of deposit issued by the Escrow Agent
or another bank having an unimpaired capital and unimpaired surplus (as defined
in 12 CFR sec. 215.2) of at least $500,000,000 and which is a member of the
Federal Reserve System, (iii) any money market mutual fund investing in United
States Treasury obligations and repurchase agreements against such obligations,
including any such fund from which the Escrow Agent or any of its affiliates may
receive compensation and (iv) direct obligations of the United States of America
or any agency thereof and obligations fully guaranteed by the United States of
America as to principal and interest, in each case having a maturity not less
than thirty (30) days and not more than ninety (90) days from the date of
issuance thereof (all such commercial paper, certificates of deposit, account
and obligations being hereinafter referred to as "Investment Securities"). The
Escrow Agent may liquidate such investments upon termination hereof pursuant to
Section 6 hereof. The Escrow Agent shall invest and reinvest any cash portion of
the Escrow Fund within the limits prescribed by this Section 5 as directed by
Hallmark in writing. If the Escrow Agent shall fail to receive written
directions from Hallmark regarding the investment of the principal of and
interest on Investment Securities at least five (5) business days before the
maturity date of such Investment Securities, the Escrow Agent shall upon the
maturity thereof with reasonable promptness reinvest such principal and interest
in Investment Securities described in clause (ii) above. Notwithstanding the
foregoing, the Escrow Agent shall be under no obligation to invest funds
aggregating less than $1,000 or integral multiples thereof. Temporarily
uninvested funds shall not earn or accrue interest. The Escrow Agent shall have
no liability whatsoever for any losses incurred as a result of any investment of
the Escrow Fund in accordance with the terms of this Section 5. The Escrow Agent
shall not be called upon to advise any party as to selling or retaining, or
taking or refraining from taking any action with respect to, any securities or
other property deposited hereunder.

                  SECTION 6. TERMINATION OF ESCROW. This Escrow Agreement and
the escrow arrangement created hereby shall be terminated upon compliance with
the terms of Section 2 hereof.

                  SECTION 7. AS TO THE ESCROW AGENT. Except as specifically
stated above, the Escrow Agent shall have no obligation to take any action in
connection with the transactions contemplated by this Agreement and shall, in
the case of any unresolved dispute between Duramed and Hallmark, be entitled to

                                      - 4 -

<PAGE>   5



take no action except upon judicial order. The Parties further severally agree
that:

                           (a)      In the event of any disagreement between the
Parties or the presentation of adverse claims or demands in connection with or
for any item deposited, the Escrow Agent shall at its option be entitled to
refuse to comply with any of such claims or demands during the continuance of
such disagreement, and in such refusal, may refrain from making any delivery of
any item deposited and in so doing, the Escrow Agent shall not become liable to
the Parties, or any of them, or to any other person, for or because of its
failure or refusal to comply with any such adverse claim or demand. The Escrow
Agent shall be entitled to continue, without liability, so to refrain and refuse
to act:

                                    (i) Until all the rights of the adverse
                           claimants have been finally adjudicated by a court
                           having competent jurisdiction of the Parties and
                           items affected hereby, after which time the Escrow
                           Agent shall be entitled to act in conformity with
                           such adjudication as directed in writing by the
                           Parties or by such court, or

                                    (ii) Until all differences shall have been
                           adjusted by agreement and the Escrow Agent shall have
                           been notified thereof and shall have been directed in
                           writing signed jointly or in counterpart by the
                           parties and by all persons making adverse claims or
                           demands at which time the Escrow Agent shall be
                           protected in acting in compliance therewith.

                                    The Escrow Agent may itself, but shall not
                           be obligated to, commence any action including a suit
                           in interpleader to resolve any disagreements. In the
                           event the Escrow Agent files a suit in interpleader,
                           it may deposit or implead property which it is
                           holding with the court, and in any event, shall upon
                           the filing of the action be ipso facto fully released
                           and discharged from all obligations further to
                           perform any and all duties or obligations imposed
                           upon it in this Agreement.

                           (b)      The duties and responsibilities of the 
Escrow Agent hereunder shall be entirely administrative and not discretionary
and shall arise solely under and in accordance with this Agreement. Except as
otherwise provided herein, in the event of a conflict or inconsistency between
the provisions of this Agreement and any other document, the provisions of this 
Agreement shall govern and be controlling. The Escrow Agent shall be obligated
to act only in accordance with written instructions received by it as provided
in this Agreement and is authorized hereby to comply with any orders, judgments
or decrees

                                      - 5 -

<PAGE>   6



of any court with or without jurisdiction and shall not be liable as a result of
its compliance with the same. The Escrow Agent may rely absolutely upon the
genuineness and authorization of the signature and purported signature of any
party upon any instruction, notice, release, receipt or other document delivered
to it pursuant to this Agreement.

                           (c)      As to any questions arising in connection 
with the administration of this Agreement, the Escrow Agent may rely absolutely
upon the opinions given to it by its counsel and shall be free of liability
for acting or failing to act in reliance on such opinions.

                           (d)      The Escrow Agent shall exercise reasonable
care in the custody of the Investment Securities in its possession or control
hereunder, but shall be deemed to have exercised reasonable care if the
Investment Securities are accorded treatment substantially equal to that which
the Escrow Agent accords its own property or if the Escrow Agent takes such
action with respect to the Investment Securities as Hallmark shall request, but
no failure to comply with any such request shall be deemed a failure to exercise
reasonable care, nor shall any failure of the Escrow Agent to take steps to
preserve rights against any parties with respect to any Investment Security be
deemed to be a failure to exercise reasonable care. Under no circumstances shall
the Escrow Agent be deemed to owe any fiduciary duties to the Parties.

                           (e)      The Parties agree to and hereby do waive any
suit, claim, demand or cause of action of any kind which it or they may have or
may assert against the Escrow Agent arising out of or relating to the execution
or performance by the Escrow Agent under this Agreement, unless such suit,
claim, demand or cause of action is based upon the willful neglect or gross
negligence or bad faith of the Escrow Agent. The Parties further agree jointly
and severally to indemnify and hold harmless the Escrow Agent against and from
any and all claims, losses, damages, demands, costs, liabilities and expenses
(collectively, "Losses"), including its attorney's fees and expenses, which may
be asserted against it or to which it may be exposed or which it may incur by
reason of its execution or performance under this Agreement (including but not
limited to Losses incurred by the Escrow Agent in connection with its successful
defense, in whole or in part, of any claim of gross negligence or willful
misconduct on its part), provided, however, that nothing contained herein shall
require the Escrow Agent to be indemnified for Losses caused by its gross
negligence or willful misconduct.

                           (f)      The Escrow Agent may at any time assign its
rights and obligations hereunder to any other bank having an unimpaired capital
and unimpaired surplus (as defined in 12 CFR sec. 215.2) of at least 
$500,000,000 and which is a member of the Federal Reserve System, which agrees
to assume such rights and

                                      - 6 -

obligations, and such successor escrow agent shall have all the powers and
duties of the Escrow Agent. The right and obligations of the Escrow Agent
hereunder shall automatically inure to any successor in interest or successor
organization to which the Escrow Agent transfers substantially all of its trust
business.

                           (g)      Duramed shall pay the Escrow Agent for its
services hereunder a one-time fee of Five Hundred Dollars ($500.00) and all
fees, expenses, disbursements and advances incurred by or made by Escrow Agent
in connection with this Agreement. In addition, Duramed shall pay the Escrow
Agent an annual fee of Two Thousand Four Hundred Dollars ($2,400.00) payable
upon execution of this Agreement and thereafter on each anniversary date of this
Agreement. The Escrow Agent shall have a first lien on all items held by it
herewith for its compensation and for any costs, liability, expense, or fees it
may incur. If any fees, expenses or costs incurred by, or any obligations owed
to, Escrow Agent hereunder are not promptly paid when due, the Escrow Agent may
reimburse itself thereof from the Escrow Fund and may sell, convey or otherwise
dispose of a portion of the Escrow Fund for such purpose. If the Escrow Agent
utilizes any portion of the Escrow Fund as provided in the previous sentence,
Duramed shall reimburse the Escrow Fund, or Hallmark if the Escrow Fund shall
have been released to Hallmark pursuant to Section 2 hereof, for the full amount
so utilized.

                           (h)      To the extent that the Escrow Agent becomes
liable for the payment of taxes, including withholding taxes, in respect of
income derived from the investment of the Escrow Fund held hereunder or any
payment made hereunder, the Escrow Agent may pay such taxes from the Escrow
Fund. The Escrow Agent may withhold from any payment of monies held by it
hereunder such amount as the Escrow Agent estimates to be sufficient to provide
the sum withheld for that purpose.

                           (i)      The Escrow Agent shall not incur any
liability for not performing any act or fulfilling any duty, obligation or
responsibility hereunder by reason of any occurrence beyond the control of the
Escrow Agent (including but not limited to any act or provision of any present
or future law or regulation or governmental authority, any act of God or war, or
the unavailability of the Federal Reserve Bank wire or telex or other wire or
communication facility).

                           (j)      This Escrow Agreement sets forth exclusively
the duties of the Escrow Agent with respect to any and all matters pertinent
hereto and no implied duties or obligations shall be read into this Escrow
Agreement against the Escrow Agent.

                  The preceding provisions in clauses (a) through (j)
shall survive the resignation or removal of the Escrow Agent, the

                                      - 7 -

assignment of this Agreement pursuant to clause (f) of this Section 7, or any
termination of this Escrow Agreement.

                  SECTION 8.  REMOVAL AND RESIGNATION OF THE ESCROW AGENT.

                           (a)      The Parties may remove the Escrow Agent at
any time by giving to the Escrow Agent thirty (30) calendar days' prior notice
in writing signed by all the Parties. The Escrow Agent may resign at any time by
giving to the Parties fifteen (15) calendar days' prior written notice thereof.

                           (b)      Within ten (10) calendar days after giving
the foregoing notice of removal to the Escrow Agent or receiving the foregoing
notice of resignation from the Escrow Agent, the Parties shall jointly agree on
and appoint a successor Escrow Agent. If a successor Escrow Agent has not
accepted such appointment by the end of such 10-day period, the Escrow Agent, in
its sole discretion, may apply to a court of competent jurisdiction for the
appointment of a successor Escrow Agent or for other appropriate relief. The
costs and expenses (including reasonable attorneys' fees and expenses) incurred
by the Escrow Agent in connection with such proceeding shall be paid by, and be
deemed a joint and several obligation of, the Parties.

                           (c)      Upon receipt of notice of the identity of 
the successor Escrow Agent, the Escrow Agent shall either deliver the Escrow
Fund then held hereunder to the successor Escrow Agent, less Escrow Agent's
fees, costs and expenses or other obligations owed to the Escrow Agent, or hold
such Escrow Fund (or any portion thereof), pending distribution, until all
such fees, costs and expenses or other obligations are paid.

                           (d)      Upon delivery of the Escrow Amount to
successor Escrow Agent, the Escrow Agent shall have no further duties,
responsibilities or obligations hereunder.

demands, directions and other communications provided for hereunder shall be in
