This Amendment No. 1 to Schedule 13D (this "Amendment") hereby amends
and supplements the Schedule 13D filed with the Securities and Exchange
Commission by Robert C. McNair, RCM Financial Services GP, Inc. and RCM
Financial Services, L.P. on July 18, 2003 (the "Schedule 13D"). This Amendment
relates to the common stock, par value $0.001 per share, of Lexicon Genetics
Incorporated. This Amendment is being filed for the sole purpose of correcting
an error in Item 6 of the Schedule 13D relating to the number of shares pledged
by the reporting persons. Except as set forth below, there are no changes to the
information in the Schedule 13D. All terms used, but not defined, in this
Amendment are as defined in the Schedule 13D.
ITEM 6. CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT
TO SECURITIES OF THE ISSUER.
The last paragraph of Item 6 of the Schedule 13D is hereby amended and
restated as follows:
"250,000 shares of Common Stock beneficially owned by RCMLP and the
General Partner and 270,000 of the shares of Common Stock beneficially
owned by Robert C. McNair are subject to pledge agreements (which
contain standard default provisions) entered into with certain
brokerage firms in connection with margin loans made by those brokerage
firms in the ordinary course of business. The reporting persons
anticipate that additional shares of Common Stock beneficially owned by
the reporting persons may become subject to similar pledge agreements."
