Re: Cardium Therapeutics, Inc. (the “Company”)

Ladies and Gentlemen:

The undersigned owns of record or beneficially certain shares of common stock,
par value $0.0001 per share (“Common Stock”), of the Company or securities
convertible into or exchangeable or exercisable for Common Stock.

This letter is being delivered to you in connection with a private placement of
Common Stock and warrants (the “Warrants”) to purchase Common Stock (the
“Offering”) for which you have acted as placement agent. The undersigned
recognizes that the Offering will be of benefit to the undersigned and will
benefit the Company by, among other things, raising additional capital for the
Company’s operations. The undersigned acknowledges that you are relying on the
representations and agreements of the undersigned contained in this letter in
carrying out the Offering.

In consideration of the foregoing, and as a condition of the closing of the
Offering, the undersigned hereby agrees that the undersigned will not (and will
cause any spouse or minor child or immediate family member of the spouse or the
undersigned living in the undersigned’s household not to), without your prior
written consent (which consent may be withheld in your sole discretion),
directly or indirectly, sell, offer, contract or grant any option to sell
(including without limitation any short sale), pledge, transfer, or otherwise
dispose of any shares of Common Stock, options or warrants to acquire shares of
Common Stock, or securities exchangeable or exercisable for or convertible into
shares of Common Stock currently or hereafter owned either of record or
beneficially (as defined in Rule 13d-3 under the Securities Exchange Act of
1934, as amended) by the undersigned (or such spouse or minor child or family
member) (collectively, the “Undersigned’s Shares”), or publicly announce an
intention to do any of the foregoing, for a period commencing on the date hereof
and continuing through the later of (i) the date that is one hundred eighty
(180) days from the closing date of the Offering, or (ii) the date that is
ninety (90) days from the effective date of the registration statement filed
under the Securities Act of 1933, as amended, covering the resale of the Common
Stock sold in the Offering, including the shares of Common Stock issuable up
exercise of the Warrants. The undersigned also agrees and consents to the entry
of stop transfer instructions with the Company’s transfer agent and registrar
against the transfer of the Undersigned’s Shares except in compliance with the
foregoing restrictions.

Notwithstanding the foregoing, the undersigned may transfer the Undersigned’s
Shares (i) as a bona fide gift or gifts, provided that the donee or donees
thereof agree in writing to be bound by the restrictions set forth herein; or
(ii) to any trust for the direct or indirect benefit of the undersigned or the
immediate family of the undersigned, provided that the trustee of the trust
agrees in writing

--------------------------------------------------------------------------------

to be bound by the restrictions set forth herein, and provided further that any
such transfer shall not involve a disposition for value. For purposes of the
foregoing, “immediate family” shall mean any relationship by blood, marriage or
adoption, not more remote than first cousin.

This agreement is irrevocable and will be binding on the undersigned and the
respective successors, heirs, personal representatives, and assigns of the
undersigned.
