Ladies and Gentlemen:


This letter is being delivered to you in connection with the Placement
Agency Agreement (the “Placement Agency Agreement”), between Redpoint
Bio Corporation, a Delaware corporation (the “Company”), and National
Securities Corporation and Brean Murray, Carret & Co. (collectively, the “Placement
Agent”) relating to the private offering of up to $28,000,000 (the “Offering”)
of Units, each comprised of one (1) share of common stock of the Company (the “Common
Stock”) and a three-year warrant to buy 25% of the number of shares of
Common Stock purchased with a cash exercise price of $3.75 per share, and which
Units are being offered at a purchase price of $2.25 per Unit to “accredited
investors” as such term is defined in Regulation D promulgated under the
Securities Act of 1933, as amended, pursuant to the Private Placement
Memorandum dated December 4, 2006, and all exhibits and supplements thereto, up
to the date hereof (the “Memorandum”). 
All capitalized terms used herein and not otherwise defined herein shall
have the meaning given such terms in the Placement Agency Agreement.  All share numbers and share prices set forth
herein do not give effect to the Merger Agreement by and among the Company, on
the one hand, and Robcor Properties, Inc., a publicly traded Florida
corporation (“Robcor”), Robcor Acquisition Corp., a Delaware corporation
and wholly-owned subsidiary of Robcor, Robcor, LLC, a Kentucky limited
liability company and wholly-owned subsidiary of Robcor and Halter Financial
Investments, L.P., a Texas limited partnership and Michael Heitz, as
stockholders of Robcor, on the other hand.


As a condition of the consummation of the Offering, the undersigned
hereby agrees that the undersigned or its assigns will not, during the period
beginning as of the date hereof and ending one hundred eighty (180) days after
the effective date of the “resale” registration statement registering the
shares of common stock underlying the securities comprising the Units (1)
offer, pledge, announce the intention to sell, sell, contract to sell, sell any
option or contract to purchase, purchase any option or contract to sell, grant
any option, right or warrant to purchase, or otherwise transfer or dispose of,
directly or indirectly, any shares of Common Stock of the Company or Pubco held
by the undersigned or any securities convertible into or exercisable or
exchangeable for Common Stock or; (2) enter into any swap, option, future,
forward or other agreement that transfers, in whole or in part, any of the
economic consequences of ownership of the Common Stock or any securities of the
Company or Pubco which are substantially similar to the Common Stock
(collectively, the “Lock-Up Securities”).  The Lock-Up Securities shall not include any
securities of Pubco issued to the undersigned in the Offering.


Notwithstanding
the foregoing, and subject to the conditions below, the undersigned may
transfer the Lock-Up Securities without the prior written consent of the
Placement Agent, provided that (1) the Placement Agent receives a signed
lock-up agreement for the balance of the lock-up period from each donee,
trustee, distributee, or transferee, as the case may be, (2) any such transfer
shall not involve a disposition for value, (3) such transfers are not required
to be reported in











any
public report or filing with the Securities Exchange Commission, or otherwise
and (4) the undersigned does not otherwise voluntarily effect any public filing
or report regarding such transfers:


(i)                                                      as a bona fide gift or gifts;


(ii)                                                   to any trust
for the direct or indirect benefit of the undersigned or the immediate family
of the undersigned;


(iii)                                                as a
distribution to limited partners or stockholders of the undersigned; or


(iv)                                               to the
undersigned’s affiliates or to any investment fund or other entity controlled
or managed by the undersigned.


Furthermore, the undersigned
may sell shares of Common Stock of the Company or Pubco purchased by the
undersigned on the open market following the Offering if and only if (i) such
sales are not required to be reported in any public report or filing with the
Securities Exchange Commission, or otherwise and (ii) the undersigned does not
otherwise voluntarily effect any public filing or report regarding such sales,
in each case (i) or (ii) above within one (1) week of such sale.


For purposes of this lock-up
agreement, “immediate family” shall mean any relationship by blood, marriage or
adoption, not more remote than first cousin.


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 Lock-Up Securities
except in compliance with the foregoing restrictions.


If at anytime any of the
persons who are entering into similar lock-up agreements (the “Lock-Up
Parties”) are released from their respective agreement, then each of the
Lock-Up Parties shall also be released from such agreements at such time on a
pro-rata basis.


If the Company notifies the
Placement Agent in writing (i) that the Company does not intend to proceed with
the Merger or the Offering, or (ii) that the Placement Agency Agreement has
been terminated (for any reason) prior to the Termination Date, this lock-up
agreement shall be terminated, and the undersigned shall be released from its
obligations hereunder.  Notwithstanding
the foregoing, this lock-up agreement shall terminate if the Offering is not
consummated by April 6, 2007.
