specified in Paragraph 2 hereof, _________ (________) fully paid and
nonassessable shares of the Company's Common Stock, par value $.01 per share
(the "Common Stock"), at an exercise price of $24.28 per share, representing
120% of the Average Price as such term is defined in that certain Development
and License Agreement (the "Development Agreement") between the parties entered
into and effective as of October 1, 2000 (the "Exercise Price"). The term
"Warrant Shares," as used herein, refers to the shares of Common Stock
purchasable hereunder. The Warrant Shares and the Exercise Price are subject to
adjustment as provided in Paragraph 4 hereof.

         This Warrant is subject to the following terms, provisions, and
conditions:

         1.  Manner of Exercise; Issuance of Certificates; Payment for Shares.
Subject to the provisions hereof, this Warrant may be exercised by the holder
hereof, in whole or in part, from time to time, by the surrender of this
Warrant, together with a completed exercise agreement in the form attached
hereto (the "Exercise Agreement"), to the Company during normal business hours
on any business day at the Company's principal executive offices (or such other
office or agency of the Company as it may designate by notice to the holder
hereof), and upon payment to the Company in cash, by certified or official bank
check or by wire transfer for the account of the Company of the Exercise Price
for the Warrant Shares specified in the Exercise Agreement. The Warrant Shares
so purchased shall be deemed to be issued to the holder hereof or such holder's
designee, as the record owner of such shares, as of the close of business on the
date on which this Warrant shall have been surrendered, the completed Exercise
Agreement shall have been delivered, and payment shall have been made for such
shares as set forth above. Certificates for the Warrant Shares so purchased,
representing the aggregate number of shares specified in the Exercise Agreement,
shall be delivered to the holder hereof within a reasonable time, not exceeding
three (3) business days, after this Warrant shall have been so exercised. The
certificates so delivered shall be in such denominations as may be requested by
the holder hereof and shall be registered in the name of such holder or such
other name as shall be designated by such holder. Notwithstanding the foregoing,
any partial exercise, other than an exercise of the total remaining shares,
shall be for at least forty thousand (40,000) shares. If under this Section 1

<PAGE>

this Warrant is exercised for less than all Warrant Shares for which this
Warrant is then exercisable, a new Warrant of like tenor and provisions for the
unexercised Warrant Shares shall then also be delivered to the holder.

         2.  Period of Exercise. This Warrant is exercisable at any time or from
time to time on or after the date hereof and through 5:00 p.m., Philadelphia
time, on the date which is the seventh-year anniversary of the date hereof (the
"Exercise Period").

         3.  Certain Agreements of the Company. The Company hereby covenants and
agrees as follows:

             (a) Shares to be Fully Paid. All Warrant Shares will, upon issuance
in accordance with the terms of this Warrant, be validly issued, fully paid, and
nonassessable and free from all taxes, liens, and charges with respect to the
issue thereof.

             (b) Reservation of Shares. The Company agrees that all times prior
to the expiration of the Exercise Period, it shall have authorized, and reserved
for the purpose of issuance upon exercise of this Warrant, a sufficient number
of shares of Common Stock to provide for the exercise of this Warrant in whole.

             (c) Listing. The Company shall promptly secure the listing of the
shares of Common Stock issuable upon exercise of this Warrant upon each national
securities exchange or automated quotation system, if any, upon which shares of
Common Stock are then listed (subject to official notice of issuance upon
exercise of this Warrant) and shall maintain, so long as any other shares of
Common Stock shall be so listed, such listing of all shares of Common Stock from
time to time issuable upon the exercise of this Warrant; and the Company shall
so list on each national securities exchange or automated quotation system, as
the case may be, and shall maintain such listing of, any other shares of capital
stock of the Company issuable upon the exercise of this Warrant if and so long
as any shares of the same class shall be listed on such national securities
exchange or automated quotation system.

             (d) Certain Actions Prohibited. The Company will not, by amendment
of its charter or through any reorganization, transfer of assets, consolidation,
merger, dissolution, issue or sale of securities, or any other voluntary action,
avoid or seek to avoid the observance or performance of any of the terms to be
observed or performed by it hereunder, but will at all times in good faith
assist in the carrying out of all the provisions of this Warrant and in the
taking of all such action as may reasonably be requested by the holder of this
Warrant in order to protect the exercise privilege of the holder of this Warrant
against dilution or other impairment, consistent with the tenor and purpose of
this Warrant. Without limiting the generality of the foregoing, the Company (i)
will not increase the par value of any shares of Common Stock receivable upon
the exercise of this Warrant above the Exercise Price then in effect, and (ii)
will take all such actions as may be necessary or appropriate in order that the
Company may validly and legally issue fully paid and nonassessable shares of
Common Stock upon the exercise of this Warrant.

<PAGE>

             (e) Successors and Assigns. This Warrant will be binding upon any
entity succeeding to the Company by merger, consolidation, or acquisition of all
or substantially all the Company's assets.

         4.  Antidilution Provisions. During the Exercise Period, the Exercise
Price and the number of Warrant Shares shall be subject to adjustment from time
to time as provided in this Paragraph 4.

             (a) Subdivision or Combination of Common Stock. If the Company at
any time subdivides (by any stock split, stock dividend, recapitalization,
reorganization, reclassification or otherwise) the shares of Common Stock
acquirable hereunder into a greater number of shares, then, after the date of
record for effecting such subdivision, the Exercise Price in effect immediately
prior to such subdivision will be proportionately reduced. If the Company at any
time combines (by reverse stock split, recapitalization, reorganization,
reclassification or otherwise) the shares of Common Stock acquirable hereunder
into a smaller number of shares, then, after the date of record for effecting
such combination, the Exercise Price in effect immediately prior to such
combination will be proportionately increased. Upon each adjustment of the
Exercise Price pursuant to the provisions of this paragraph , the number of
shares of Common Stock issuable upon exercise of this Warrant shall be adjusted
by multiplying a number equal to the Exercise Price in effect immediately prior
to such adjustment by the number of shares of Common Stock issuable upon
exercise of this Warrant immediately prior to such adjustment and dividing the
product so obtained by the adjusted Exercise Price.

             (b) Consolidation, Merger or Sale. In case of any consolidation of
the Company with, or merger of the Company with or into any other corporation,
or in case of any sale or conveyance of all or substantially all of the assets
of the Company other than in connection with a plan of complete liquidation of
the Company, then as a condition of such consolidation, merger or sale or
conveyance, adequate provision will be made whereby the holder of this Warrant
will have the right to acquire and receive upon exercise of this Warrant in lieu
of the shares of Common Stock immediately theretofore acquirable upon the
exercise of this Warrant, such shares of stock, securities or assets as may be
issued or payable with respect to or in exchange for the number of shares of
Common Stock immediately theretofore acquirable and receivable upon exercise of
this Warrant had such consolidation, merger or sale or conveyance not taken
place. The Company will not effect any consolidation, merger or sale or
conveyance unless prior to the consummation thereof, the successor corporation
(if other than the Company) assumes by written instrument the obligations under
this Paragraph 4 and the obligations to deliver to the holder of this Warrant
such shares of stock, securities or assets as, in accordance with the foregoing
provisions, the holder may be entitled to acquire.

             (c) Notice of Adjustment. Upon the occurrence of any event which
requires any adjustment of the Exercise Price, then, and in each such case, the
Company shall give notice thereof to the holder of this Warrant, which notice
shall state the Exercise Price resulting from such adjustment and the increase
or decrease in the number of Warrant Shares purchasable at such price upon
exercise, setting forth in reasonable detail the method of calculation and the
facts upon which such calculation is based. Such calculation shall be certified
by the chief financial officer of the Company.

<PAGE>

             (d) Minimum Adjustment of Exercise Price. In the event that any
adjustment of the Exercise Price as required herein results in a fraction of a
cent, such Exercise Price shall be rounded up to the nearest cent. No adjustment
of the Exercise Price shall be made in an amount of less than 1% of the Exercise
Price in effect at the time such adjustment is otherwise required to be made,
but any such lesser adjustment shall be carried forward and shall be made at the
time and together with the next subsequent adjustment which, together with any
adjustments so carried forward, shall amount to not less than 1% of such
Exercise Price.

             (e) No Fractional Shares. No fractional shares of Common Stock are
to be issued upon the exercise of this Warrant, but the Company shall pay a cash
adjustment in respect of any fractional share which would otherwise be issuable
in an amount equal to the same fraction of the Market Price of a share of Common
Stock on the date of such exercise.

             (f) Other Notices. In case at any time:

                 (i)   the Company shall declare any dividend upon the Common
Stock payable in shares of stock of any class or make any other distribution
(including dividends or distributions payable in cash out of retained earnings)
to the holders of the Common Stock;

                 (ii)  the Company shall offer for subscription pro rata to the
holders of the Common Stock any additional shares of stock of any class or other
rights;

                 (iii) there shall be any capital reorganization of the Company,
or reclassification of the Common Stock, or consolidation or merger of the
Company with or into, or sale of all or substantially all its assets to, another
corporation or entity; or

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

then, in each such case, the Company shall give to the holder of this Warrant
(a) notice of the date on which the books of the Company shall close or a record
shall be taken for determining the holders of Common Stock entitled to receive
any such dividend, distribution, or subscription rights or for determining the
holders of Common Stock entitled to vote in respect of any such reorganization,
reclassification, consolidation, merger, sale, dissolution, liquidation or
winding-up and (b) in the case of any such reorganization, reclassification,
consolidation, merger, sale, dissolution, liquidation or winding-up, notice of
the date (or, if not then known, a reasonable approximation thereof by the
Company) when the same shall take place. Such notice shall also specify the date
on which the holders of Common Stock shall be entitled to receive such dividend,
distribution, or subscription rights or to exchange their Common Stock for stock
or other securities or property deliverable upon such reorganization,
reclassification, consolidation, merger, sale, dissolution, liquidation, or
winding-up, as the case may be. Such notice shall be given at least 30 days
prior to the record date or the date on which the Company's books are closed in
respect thereto. Failure to give any such notice or any defect therein shall not
affect the validity of the proceedings referred to in clauses (i), (ii), (iii)
and (iv) above.

<PAGE>

         5.  Issue Tax. The issuance of certificates for Warrant Shares upon the
exercise of this Warrant shall be made without charge to the holder of this
Warrant or such shares for any issuance tax or other costs in respect thereof,
provided that the Company shall not be required to pay any tax which may be
payable in respect of any transfer involved in the issuance and delivery of any
certificate in a name other than the holder of this Warrant.

         6.  No Rights or Liabilities as a Shareholder. This Warrant shall not
entitle the holder hereof to any voting rights or other rights as a shareholder
of the Company. No provision of this Warrant, in the absence of affirmative
action by the holder hereof to purchase Warrant Shares, and no mere enumeration
herein of the rights or privileges of the holder hereof, shall give rise to any
liability of such holder for the Exercise Price or as a shareholder of the
Company, whether such liability is asserted by the Company or by creditors of
the Company.

         7.  Transfer and Replacement of Warrant.

             (a) Restrictions on Transfer. The Warrant and the rights granted to
the holder hereof are non-transferable. Notwithstanding the foregoing, the
holder hereof may at any time assign this Warrant in whole or in part to any
affiliate of the holder.

             (b) Replacement of Warrant. Upon receipt of evidence reasonably
satisfactory to the Company of the loss, theft, destruction, or mutilation of
this Warrant and, in the case of any such loss, theft, or destruction, upon
delivery of an indemnity agreement reasonably satisfactory in form and amount to
the Company, or, in the case of any such mutilation, upon surrender and
cancellation of this Warrant, the Company, at its expense, will execute and
deliver, in lieu thereof, a new Warrant of like tenor.

             (c) Cancellation; Payment of Expenses. Upon the surrender of this
Warrant in connection with any transfer or replacement as provided in this
Paragraph 7, this Warrant shall be promptly canceled by the Company. The Company
shall pay all taxes (other than securities transfer taxes) and all other
expenses (other than legal expenses, if any, incurred by the Holder) and charges
payable in connection with the preparation, execution, and delivery of Warrants
pursuant to this Paragraph 7.

             (d) Register. The Company shall maintain, at its principal
executive offices (or such other office or agency of the Company as it may
designate by notice to the holder hereof), a register for this Warrant, in which
the Company shall record the name and address of the person in whose name this
Warrant has been issued, as well as the name and address of each assignee and
each prior owner of this Warrant.

             (e) Exercise Without Registration. If, at the time of the surrender
of this Warrant in connection with any exercise of this Warrant, this Warrant
(or, in the case of any exercise, the Warrant Shares issuable hereunder), shall
not be registered under the Securities Act of 1933, as amended (the "Securities

<PAGE>

Act"), and under applicable state securities or blue sky laws, the Company may
require, as a condition of allowing such exercise, (i) that the holder of this
Warrant, as the case may be, furnish to the Company a written opinion of
counsel, which opinion and counsel are acceptable to the Company, to the effect
that such exercise may be made without registration under said Act and under
applicable state securities or blue sky laws and (ii) that the holder execute
and deliver to the Company an investment letter in form and substance acceptable
to the Company. The first holder of this Warrant, by taking and holding the
same, represents to the Company that such holder is acquiring this Warrant for
investment and not with a view to the distribution thereof. Notwithstanding the
foregoing, if this Warrant is presented for exercise by the initial Holder
hereof, the foregoing provisions of this Section 7 shall not apply to the
exercise of this Warrant by the initial Holder hereof.

         8.  Registration Rights. The initial holder of this Warrant is entitled
to the benefit of such registration rights in respect of the Warrant Shares as
are set forth in Article 11 of the Development Agreement.

         9.  Notices. All notices, requests, and other communications required
or permitted to be given or delivered hereunder to the holder of this Warrant
shall be in writing, and shall be personally delivered, or shall be sent by
certified or registered mail or by recognized overnight mail courier, postage
prepaid and addressed, to such holder at the address shown for such holder on
the books of the Company, or at such other address as shall have been furnished
to the Company by notice from such holder. All notices, requests, and other
communications required or permitted to be given or delivered hereunder to the
Company shall be in writing, and shall be personally delivered, or shall be sent
by certified or registered mail or by recognized overnight mail courier, postage
prepaid and addressed, to the office of the Company at 375 Phillips Boulevard,
Ewing, New Jersey 08618, Attention: Chief Executive Officer, or at such other
address as shall have been furnished to the holder of this Warrant by notice
from the Company. Any such notice, request, or other communication may be sent
by facsimile, but shall in such case be subsequently confirmed by a writing
personally delivered or sent by certified or registered mail or by recognized
overnight mail courier as provided above. All notices, requests, and other
communications shall be deemed to have been given either at the time of the
receipt thereof by the person entitled to receive such notice at the address of
such person for purposes of this Paragraph 9, or, if mailed by registered or
certified mail or with a recognized overnight mail courier upon deposit with the
United States Post Office or such overnight mail courier, if postage is prepaid
and the mailing is properly addressed, as the case may be.

         10. Governing Law. This warrant shall be governed by and construed and
enforced in accordance with the internal laws of the Commonwealth of
Pennsylvania without regard to the body of law controlling conflicts of law.

         11. Miscellaneous.

             (a) Amendments. This Warrant and any provision hereof may only be
amended by an instrument in writing signed by the Company and the holder hereof.
