Common Stock

Date of Issue:  October 1, 2003

REGEN BIOLOGICS, INC., a Delaware corporation (the “Company”), and _________ (the “Holder”), hereby agree that, for value received, the Holder is entitled to purchase from the Company, subject to the terms and conditions set forth below, at any time after the date hereof (the “Determination Date”) and on or before the Expiration Date (as defined in Section 2.5 hereof), _______ shares of fully paid and non-assessable Common Stock, par value $0.01 per share (the “Common Stock”) of the Company (the “Shares”), at a purchase price per Share specified in Section 1.2 hereof (the “Warrant Price”).  The number of Shares subject to this Warrant and the Warrant Price shall be subject to adjustment from time to time after the Determination Date pursuant to the terms and conditions in Section 3 hereof.

1.              Number of Shares and Warrant Price.

1.1.           Number of Shares.  The number of Shares shall be ________.

1.2.           Warrant Price.  The Warrant Price shall be equal to $0.45 per share, which price has been determined by the Board of Directors of the Company in good faith.

2.             Exercise of Warrant.

2.1.           Mechanics of Exercise.  The Holder may exercise this Warrant after the Determination Date in whole or in part by surrendering this Warrant and a duly executed Notice of Exercise in substantially the form attached hereto as Exhibit A at the principal executive offices of the Company.  The Holder shall also deliver to the Company simultaneously with the Holder’s Notice of Exercise payment of the aggregate Warrant Price for the Shares being purchased.  The consideration for the exercise of this Warrant may be in the form of a bank cashier’s or certified check payable to the order of the Company, or by wire transfer to an account designated in writing by the Company.  In the event that the Holder elects to exercise less than the full number of Shares recorded above, the Company will execute and deliver to the Holder a Warrant of like tenor in the number of Shares granted by the Company less the number of Shares exercised.

2.2.           Net Exercise.  In lieu of exercising this Warrant as specified in Section 2.1, the Holder may from time to time after the Determination Date elect to receive, without the payment by the Holder of any additional consideration, Shares equal to the value of this Warrant (or the portion thereof being exercised) by surrendering this Warrant and a duly executed Notice of Exercise in substantially the form attached hereto as Exhibit A at the principal executive offices of the Company, in which event the Company shall issue to the Holder a number of Shares determined using the following formula:

	Y (A - B)
X  =	-----------------------
	A

Where:

X = The number of Shares to be issued to the Holder pursuant to this net exercise election

Y = The number of Shares in respect of which the net exercise election is made

A = The fair market value of one share of Common Stock of the Company at the time the net exercise election is made

B = The Warrant Price (as adjusted to the date of the net exercise election).

If the Common Stock of the Company is traded regularly in a public market, the fair market value of a share of Common Stock of the Company shall be equal to the average closing price of a share of Common Stock of the Company reported for the twenty (20) day trading period ending on the date immediately prior to the date on which the Holder delivers its Notice of Exercise to the Company.  If the Common Stock of the Company is not regularly traded in a public market, the Board of Directors of the Company shall determine, in its reasonable good faith judgment, the fair market value of a share of Common Stock of the Company as of the date immediately prior to the date on which the Holder delivers its Notice of Exercise to the Company.  In the event that the Holder elects to exercise less than the full number of Shares recorded above, the Company will execute and deliver to the Holder a Warrant of like tenor in the number of Shares granted by the Company less the number of Shares exercised.

2.3.           When Exercise Effective.  The exercise of this Warrant shall be deemed to have been effective for the Holder immediately prior to the close of business on the business day on which this Warrant is surrendered to the Company as provided in Section 2.1 or Section 2.2, and at such time the person or persons in whose name or names any certificate or certificates for Shares shall be issuable upon such exercise as provided in Section 2.4 shall be deemed to have become the holder or holders of record thereof.

 2.4.           Delivery of Stock Certificates, Etc.  As soon as practicable after the surrender of this Warrant, the Company will cause to be issued in the name of, and delivered to, the Holder a certificate or certificates for the number of fully paid and non-assessable Shares which the Holder has purchased.

-2-

2.5.           Expiration Date. This Warrant shall expire on the fifth anniversary of the date of issuance.

3.           Adjustments.

3.1.           Adjustment for Certain Dividends and Distributions.  If the Company at any time or from time to time after the Determination Date makes, or fixes a record date for the determination of holders of shares of Common Stock entitled to receive, a dividend or other distribution payable in additional shares of the Company’s equity securities, then, and in each such event, the number of Shares theretofore receivable upon the exercise of this Warrant shall be proportionately increased as of the time of such issuance or, in the event such record date is fixed, as of the close of business on such record date; provided, however, that if such record date is fixed and such dividend is not fully paid or if such distribution is not fully made on the date fixed therefor, the number of Shares theretofore receivable upon exercise of this Warrant shall be recomputed accordingly as of the close of business on such record date, and thereafter the number of Shares theretofore receivable upon exercise of this Warrant shall be adjusted pursuant to this Section 3.1 as of the time of actual payment of such dividends or distributions.

3.2.           Stock Split and Reverse Stock Split.  If the Company at any time or from time to time after the Determination Date effects a stock split or subdivision of the outstanding Common Stock, the number of Shares theretofore receivable upon the exercise of this Warrant shall be proportionately increased.  If the Company at any time or from time to time after the Determination Date effects a reverse stock split or combines the outstanding shares of Common Stock into a smaller number of shares, the number of Shares theretofore receivable upon the exercise of this Warrant shall be proportionately decreased.  Appropriate adjustments shall also be made to the Warrant Price, but the aggregate Warrant Price shall remain the same.  Each adjustment under this Section 3.2 shall become effective at the close of business on the date the stock split, subdivision, reverse stock split or combination becomes effective.

3.3.           Merger, Sale of Assets, Etc.  If after the Determination Date and at any time while this Warrant, or any portion thereof, is outstanding and unexpired there shall be (i) a reorganization (other than a combination, reclassification, exchange or subdivision of shares otherwise provided for herein), (ii) a merger or consolidation of the Company with or into another corporation in which the Company is not the surviving entity, or a reverse triangular merger in which the Company is the surviving entity but the shares of the Company’s capital stock outstanding immediately prior to the merger are converted by virtue of the merger into other property (whether in the form of securities, cash or otherwise), or (iii) a sale or transfer of the Company’s properties and assets as, or substantially as, an entirety to any other person, this Warrant shall thereafter represent the right to acquire for the Aggregate Warrant Price (as defined below) the number of shares of stock or other securities which the Holder of this Warrant would have owned immediately after the consummation of such reorganization, merger, consolidation, sale or transfer, if the Holder of this Warrant had exercised this Warrant immediately before the effective date of the reorganization, merger, consolidation, sale or transfer.  In each such case, the terms of this Warrant shall be applicable to the shares of stock or other securities receivable upon exercise of this Warrant after such consummation.  For purposes of this Section 3.3, the “Aggregate Warrant Price” shall mean the aggregate consideration obtained by multiplying (x) the Warrant Price by (y) the maximum number of Shares of Common Stock for which this Warrant was exercisable immediately prior to such conversion or redemption.
