EXHIBIT F

POLICY REGARDING SECURITIES HANDLING OF NONPUBLIC INFORMATION

     This Policy sets forth requirements that all Employees and agents of ReGen Biologics, Inc. (“ReGen”) must follow, arising from its responsibilities as a public company. In view of the potential for abuse, this Policy is also applicable to relatives who share the same home with Employees, agents or persons under the control of Employees, agents or such relatives (such Employees, agents, relatives and control persons are referred to collectively herein as “Subject Person(s)”).

In order for Subject Persons to comply with the Policy, it is important they understand the meaning and scope of the following terms:

            1. Material Information. Information is material for purposes of this Policy if (i) there is a substantial likelihood an investor would consider it important in deciding whether to buy, sell or hold a security, or (ii) disclosure of the information would have a significant impact on the price of a security. Information can be material (a) whether it is positive or negative, (b) whether it was received from ReGen or from a source not connected with ReGen, (c) whether it affects ReGen or its business, financial condition, results of operations, assets, net worth or future prospects, or affects the market price of ReGen’s common stock (“Common Stock”), or (d) even thought it would not by itself determine an investor’s decision or affect the market price. It is important to bear in mind that information need not be historical or certain to be material; events or financial forecasts that are uncertain or contingent may also be material depending on their magnitude and likelihood of occurrence.

            Although it is not possible to list all types of information that may be “material,” information concerning the following events should be presumed to be “material” for purposes of this Policy: results of operation, especially earnings; financial forecasts, especially estimates of earnings; significant changes in previously disclosed financial information; increases or decreases in dividends or the decision to declare dividends; declaration of stock splits and stock dividends; proposals or agreements regarding mergers, acquisitions or dispositions; proposed issuances of new securities; significant expansion or reduction of operations; significant increases or decreases in business; the award or loss of a significant contract; significant development of new products or services to be introduced; significant changes in borrowings; significant license arrangements; major litigation or contingent liabilities or obligations; significant changes in financial liquidity; other significant positive or negative events; and significant changes in management. This list is not exhaustive. Other types of information may be material at any particular time, depending on the circumstances.

            WHEN IN DOUBT, INFORMATION SHOULD ALWAYS BE PRESUMED TO BE MATERIAL.

            2. Nonpublic. In order for information to be considered “publicly available” or “made available to the public,” and therefore no longer “nonpublic” for purposes of this Policy, it must have been released by ReGen through appropriate public media in a manner designed to achieve a broad dissemination to the investing public generally and without favoring any special person or group. Information should be considered to have been “made available to the public” or “publicly available” only if (i) it has been disclosed in an annual or quarterly report by ReGen (or ReGen with which we have or are proposing to have business dealings, as

the case may be), (ii) it has been included in a widely disseminated press release intended for and made available to the general public, or (iii) it has been widely reported in the media. Any information which does not meet these standards is considered “nonpublic.” Any doubts in this regard should be resolved in favor of considering it “nonpublic.”

     3. Security. The term “security” includes the Common Stock and any put, call, option, warrant, right or privilege with respect to the Common Stock. Securities also include preferred stock, certain debt instruments, and securities indices. All types of securities are covered by this Policy, whether or not they are traded on an exchange or in the over-the-counter market or otherwise.
