Item 1.  Security and Issuer.
         -------------------

              This statement relates to the common stock, par value $0.0001 per
share (the "Common Stock"), of Rexahn Pharmaceuticals, Inc., a Delaware
corporation (the "Issuer"). The Issuer's principal executive office is located
at 9620 Medical Center Drive, Rockville, MD 20850.


Item 2.  Identity and Background.
         -----------------------

              This statement is being filed by Dr. Young-Soon Park, a citizen of
the Republic of Korea. Dr. Park is the Chairman of Onnuri Health Group and
Onnuri Pharmaceutical Chain Co., Ltd., a chain of pharmacies whose principal
executive office is located at 667-16 Yeuksam-dong Kangnam-gu, Seoul, Korea, and
a director of the Issuer.

              During the last five years, Dr. Park has not (i) been convicted in
a criminal proceeding (excluding traffic violations or similar misdemeanors), or
(ii) been a party to a civil proceeding of a judicial or administrative body of
competent jurisdiction as a result of which Dr. Park was or is subject to a
judgment, decree or final order enjoining future violations of, or prohibiting
or mandating activities subject to, federal or state securities laws or finding
any violation with respect to such laws.


Item 3.  Source and Amount of Funds or Other Consideration.
         -------------------------------------------------

              Dr. Park acquired beneficial ownership of 9,250,660 shares of
Common Stock from the Issuer in connection with the Merger described in Item 4.


Item 4.  Purpose of Transaction.
         ----------------------

              The acquisition was made in connection with the Agreement and Plan
of Merger dated as of January 20, 2005 (the "Merger Agreement") by and among
Corporate Road Show.Com Inc., a New York corporation ("CPRD"), CRS Merger Sub,
Inc., a Delaware corporation and wholly owned subsidiary of CPRD ("Merger Sub"),
CRS Delaware, Inc., a Delaware corporation and wholly owned subsidiary of CPRD
("CRS Delaware"), and Rexahn, Corp, a Maryland corporation ("Rexahn"), pursuant
to which, immediately after giving effect to a 1-for-100 reverse stock split and
the reincorporation of CPRD as a Delaware corporation under the name "Rexahn
Pharmaceuticals, Inc.", Merger Sub merged with and into Rexahn, with Rexahn as
the surviving corporation (the "Surviving Company") and a wholly-owned
subsidiary of CPRD (the "Merger"). In the Merger, each share of Rexahn common
stock issued and outstanding prior to the Merger was converted into five shares
of Common Stock. Immediately prior to the Merger, Dr. Park beneficially owned
581,800 shares of Rexahn common stock directly and 33,200 shares of Rexahn
common stock indirectly through the Korean Rexahn Investors Voting Trust (the
"Voting Trust") described under Item 6 below. Dr. Park is also the co-trustee of

Dr. Park's 33,200 shares) immediately prior to the Merger.

              (a) As of the date hereof, Dr. Park beneficially owns 9,250,660
shares of Common Stock, representing 22.3% of the outstanding shares of Common

direct the vote with Chang H. Ahn, the other co-trustee of the Voting Trust. Dr.

years, to the knowledge of Dr. Park, Dr. Ahn has not (i) been convicted in a
criminal proceeding (excluding traffic violations or similar misdemeanors), or
(ii) been a party to a civil proceeding of a judicial or administrative body of
competent jurisdiction as a result of which Dr. Ahn was or is subject to a
judgment, decree or final order enjoining future violations of, or prohibiting
or mandating activities subject to, federal or state securities laws or finding
any violation with respect to such laws.

              (c) Except for the acquisition reported herein, Dr. Park has not
effected any other transaction in the Common Stock within the past 60 days.

              (d) Any dividends in respect of shares of Common Stock held in the
Voting Trust in shares of capital stock of the Issuer shall be deposited into
the Voting Trust; however, the registered holders of the Voting Trust
Certificates shall receive all other dividends directly from the Issuer. Any
transfer or disposition of shares of Common Stock is subject to the Voting
Trust.

              (e) Not applicable.
