EXHIBIT 10.11
                                                                  CONFORMED COPY

                       AMENDMENT TO STOCK ESCROW AGREEMENT

         AMENDMENT, dated October 31, 2005, to STOCK ESCROW AGREEMENT, dated as
of February 12, 2004 ("Escrow Agreement"), by and among CEA ACQUISITION
CORPORATION, a Delaware corporation ("Company"), CEA GROUP, LLC, ROBERT MOREYRA,
DONALD RUSSELL, HAROLD EWEN and BRAD GORDON (collectively "Initial
Stockholders") and CONTINENTAL STOCK TRANSFER & TRUST COMPANY, a New York
corporation ("Escrow Agent"). Capitalized terms that are defined in the Escrow
Agreement shall have the same meanings as used in the Escrow Agreement.

         The parties hereto, being all of the parties to the Escrow Agreement,
hereby agree that the Escrow Agreement is hereby amended as follows:

         1. A new Section 3A is hereby added to the Escrow Agreement,
immediately following Section 3 and reading as follows:

                  3A. Extension of Escrow Period; Trigger Condition. Effective
upon the date (the "Closing Date") of the consummation of the Business
Combination with etrials Worldwide, Inc. ("etrials"), in accordance with the
Agreement and Plan of Merger dated August 22, 2005, by and among the Company,
etrials Acquisition, Inc., etrials and certain stockholders of etrials, as
amended (the "Merger Agreement"), the Escrow Period shall be extended, but only
with respect to the Trigger Shares (as hereinafter defined), until the date that
is the earlier of (a) the Trigger Release Date (as hereinafter defined) and (b)
February 19, 2008. In no event, however, shall the Trigger Release Date be
earlier than the third anniversary of the Effective Date. As used herein, the
term "Trigger Shares" means, with respect to each Initial Stockholder, the
number of shares of Company Common Stock listed next to his name on the
signature page hereof and the term "Trigger Release Date" means the last day of
the first twenty (20) consecutive trading day period commencing after the
Closing Date during which (i) the volume-weighted average price of the Company's
Common Stock is equal to or greater than $7.00 per share and (ii) the average
daily trading volume of the Company's Common Stock is at least 25,000 shares (in
each case based on information obtained from the equity page for the Company
provided by the Bloomberg reporting service). If the Trigger Release Date does
not occur by February 19, 2008, the Trigger Shares shall be canceled by the
Escrow Agent in its capacity as Transfer Agent of the Company and the
certificates representing the Trigger Shares shall be destroyed by the Escrow
Agent. For purposes hereof, the delivery to the Escrow Agent of a "Trigger
Release Notice" that has become effective pursuant to Section 4(b) of the
Revised Escrow Agreement (as defined in the Merger Agreement) shall be
sufficient to establish the occurrence of the Trigger Release Date. The Initial
Stockholders shall deliver to the Escrow Agent sufficient stock powers executed
in blank, with medallion signature guarantees, to enable the Escrow Agent, in
its capacity as Transfer Agent of the Company, to reissue the Escrow Shares in
such denominations as will provide separate stock certificates for each Initial
Stockholder's Trigger Shares.

         2. The Escrow Agreement, as hereby amended, shall remain in full force
and effect.

         IN WITNESS WHEREOF, the parties have executed this Amendment to Escrow
Agreement as of the date first above written.
