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

This Amendment No. 1 (this "Amendment") amends and supplements the
statement on Schedule 13D, filed January 21, 2005 relating to the common stock,
par value $0.0001 per share, of Corporate Road Show.Com Inc., a New York
corporation ("CPRD").

Pursuant to an Agreement and Plan of Merger dated as of January
20, 2005 (the "Merger Agreement") by and among CPRD, CRS Merger Sub, a Delaware
corporation and wholly owned subsidiary of CPRD ("Merger Sub"), CRS Delaware, a
Delaware corporation and a wholly owned subsidiary of CPRD ("CRS Delaware"), and
Rexahn, Corp, a Maryland corporation ("Rexahn"), and 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." (the
"Issuer"), Merger Sub merged with and into Rexahn, with Rexahn surviving as a
wholly owned operating subsidiary of the Issuer (the "Merger"). The Merger was
effective as of May 13, 2005. In the Merger, each share of Rexahn common stock
was automatically converted into five shares of common stock, par value $0.0001
per share (the "Common Stock"), of the Issuer. Immediately prior to the
effective time of the Merger, Rexahn had outstanding 7,628,166 shares of its
common stock and approximately 38,140,830 shares of Common Stock were issued to
the holders of Rexahn common stock in exchange for their Rexahn shares in the
Merger.

As a result of the reverse stock split and reincorporation, the
163,800,000 shares of common stock, par value $0.0001 per share, of CPRD
beneficially owned by Dr. Sung-Kee Chung became 1,638,000 shares of Common
Stock.

This Amendment is filed pursuant to Rule 13d-2(a) promulgated
under the Securities Exchange Act of 1934, as amended, to report that as a
result of the issuance of 38,140,830 additional shares of Common Stock in the
Merger, Dr. Chung's beneficial ownership of Common Stock is less than 5% of the
outstanding shares of Common Stock as of May 13, 2005.


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

This Amendment is being filed by Dr. Chung, a citizen of the
United States. Dr. Chung is a professor at Pohang University of Sciences &
Technology, and resides at 756 Jigok-dong, Postech Faculty APT 9-201, Pohang
790-751, Korea.

During the last five years, Dr. Chung has not (i) been convicted
