                               SECURITY AGREEMENT

     This Security Agreement is made as of September 21, 2001 between Curon
Medical, Inc., a Delaware corporation ("Pledgee"), and John Gaiser ("Pledgor").

     1. Note Issuance. Pledgee has agreed to lend Pledgor $75,000 pursuant to a
        -------------
promissory note (the "Note"). The Note and the obligations thereunder are as set
forth in Exhibit A to this Security Agreement.
         ---------

     2. Creation and Description of Security Interest. Pledgor, pursuant to the
        ---------------------------------------------
California Commercial Code, hereby pledges sixty thousand (60,000) shares of the
Common Stock of Curon Medical, Inc., a Delaware corporation (herein sometimes
referred to as the "Collateral" or the "Pledged Stock") and shall deliver said
certificate to the Secretary of Pledgee ("Pledgeholder") within 30 days hereof,
who shall hold said certificate subject to the terms and conditions of this
Security Agreement.

     The pledged stock (together with an executed blank stock assignment
attached hereto as Exhibit B for use in transferring all or a portion of the
                   ---------
Shares to Pledgee if, as and when required pursuant to this Security Agreement)
shall be held by the Pledgeholder as security for the repayment of the Note, and
any extensions or renewals thereof, and the Pledgeholder shall not encumber or
dispose of such Shares except in accordance with the provisions of this Security
Agreement.

     3. Pledgor's Representations and Covenants. To induce Pledgee to enter into
        ---------------------------------------
this Security Agreement, Pledgor represents and covenants to Pledgee, its
successors and assigns, as follows:

   Payment of Indebtedness. Pledgor will pay the principal sum of the Note
   -----------------------
secured hereby, together with interest thereon, at the time and in the manner
provided in the Note.

   Encumbrances. The Shares are free of all other encumbrances, defenses and
   ------------
liens, and Pledgor will not further encumber the Shares without the prior
written consent of Pledgee.

   Margin Regulations. In the event that Pledgee's Common Stock is now or later
   ------------------
becomes margin-listed by the Federal Reserve Board and Pledgee is classified as
a "lender" within the meaning of the regulations under Part 207 of Title 12 of
the Code of Federal Regulations ("Regulation G"), Pledgor agrees to cooperate
with Pledgee in making any amendments to the Note or providing any additional
collateral as may be necessary to comply with such regulations.

     4. Voting Rights. During the term of this pledge and so long as all
        -------------
payments of principal and interest are made as they become due under the terms
of the Note, Pledgor shall have the right to vote all of the Shares pledged
hereunder.

     5. Stock Adjustments. In the event that during the term of the pledge any
        -----------------
stock dividend, reclassification, readjustment or other changes are declared or
made in the capital structure of Pledgee, all new, substituted and additional
shares or other securities issued by reason of any such change shall be
delivered to and held by the Pledgee under the terms of this Security Agreement
in the same manner as the Shares originally pledged hereunder. In the event of
substitution of such


<PAGE>

securities, Pledgor, Pledgee and Pledgeholder shall cooperate and execute such
documents as are reasonable so as to provide for the substitution of such
Collateral and, upon such substitution, references to "Shares" in this Security
Agreement shall include the substituted shares of capital stock of Pledgor as a
result thereof.

     6. Default. Pledgor shall be deemed to be in default of the Note and of
        -------
this Security Agreement in the event that payment of principal or interest on
the Note shall be delinquent for a period of 30 days or more. In the case of
default, Pledgee shall have the right to accelerate payment of the Note upon
notice to Pledgor, and Pledgee shall thereafter be entitled to pursue its
remedies under the California Commercial Code.

     7. Release of Collateral. Subject to any applicable contrary rules under
        ---------------------
Regulation G, there shall be released from this pledge a portion of the Pledged
Shares held by Pledgeholder hereunder upon payments of the principal of the
Note. The number of the Pledged Shares which shall be released shall be that
number of full shares which bears the same proportion to the initial number of
shares pledged hereunder as the payment of principal bears to the initial full
principal amount of the Note.

     8. Withdrawal or Substitution of Collateral. Pledgor shall not sell,
        ----------------------------------------
withdraw, pledge, substitute or otherwise dispose of all or any part of the
Collateral without the prior written consent of Pledgee.

     9. Term. The within pledge of Shares shall continue until the payment of
        ----
all indebtedness secured hereby, at which time the remaining pledged stock shall
be promptly delivered to Pledgor, subject to the provisions for prior release of
a portion of the Collateral as provided in paragraph 7 above.

     10. Insolvency. Pledgor agrees that if a bankruptcy or insolvency
         ----------
proceeding is instituted by or against it, or if a receiver is appointed for the
property of Pledgor, or if Pledgor makes an assignment for the benefit of
creditors, the entire amount unpaid on the Note shall become immediately due and
payable, and Pledgee may proceed as provided in the case of default.

     11. Pledgeholder Liability. In the absence of willful or gross negligence,
         ----------------------
Pledgeholder shall not be liable to any party for any of his acts, or omissions
to act, as Pledgeholder.

     12. Invalidity of Particular Provisions. Pledgor and Pledgee agree that the
         -----------------------------------
enforceability or invalidity of any provision or provisions of this Security
Agreement shall not render any other provision or provisions herein contained
unenforceable or invalid.

     13. Successors or Assigns. Pledgor and Pledgee agree that all of the terms
         ---------------------
of this Security Agreement shall be binding on their respective successors and
assigns, and that the term "Pledgor" and the term "Pledgee" as used herein shall
be deemed to include, for all purposes, the respective designees, successors,
assigns, heirs, executors and administrators.

     14. Governing Law. This Security Agreement shall be interpreted and
         -------------
governed under the internal substantive laws, but not the choice of law rules,
of California.
