            EMPLOYEE CONFIDENTIALITY AND NON-SOLICITATION AGREEMENT

In consideration of my employment and/or continued employment by Clinical Data,
Inc., a Delaware corporation having a principal place of business at One Gateway
Center, Suite 702, Newton, Massachusetts 02458(hereinafter referred to as the
"Employer"), or by any of its subsidiaries, divisions or affiliates, and its
successors and assigns, and in further consideration of the salary paid or to be
paid me by the Employer, and other consideration, the receipt and sufficiency of
which are hereby acknowledged, I agree as follows:

      1.    All non-public, confidential information communicated to me by the
            Employer relating to or concerning its business will be treated as
            confidential and proprietary trade secret information of Employer.
            Unless authorized in writing or instructed by the Employer or
            required by the lawful order or legally constituted authority, I
            will not, except as required in the conduct of the Employer's
            business, during or after my employment, disclose to others, or use,
            any of the Employer's inventions or discoveries or its secret or
            confidential information, knowledge or data which I may obtain as a
            result of my employment relating to the business or activities of
            the Employer, whether or not developed by me, unless and until, and
            then to the extent and only to the extent that such information,
            knowledge or date becomes available to the public otherwise than by
            my fault or omission.

      2.    I understand that information relating to the business plans,
            present and prospective customers and representatives of the
            Employer, business dealings with, proposals to and working
            agreements and relationships with such customers and prospective
            representatives of the Employer shall be subject to the same
            restrictions as in paragraph (1).

      3.    I also agree that for a one (1) year period after the termination of
            my employment for any reason, I will not, directly or indirectly,
            (a) solicit, call on, or otherwise deal in any way with any prospect
            customer, vendor or contractor with whom the Employer shall have
            dealt during the last two (2) years of my employment with the
            Employer (or, if I have been employed for less than two (2) years,
            during the entire duration of my employment) for a purpose which is
            competitive with the business of the Employer, or influence any such
            customer, vendor or contractor to terminate or modify any agreement
            or course of dealing with the Employer; and (b) solicit the
            employment of any employee of the Employer still in the Employer's
            employment at the time of the termination of my employment.

      4.    Upon termination of my employment for any reason, or at any time at
            the Employer's request, I shall deliver to the Employer, all keys,
            materials, documents, plans, records, notebooks, notes, written
            information, drawings or papers, and any copies thereof, in any way
            relating to the business or activities of the Employers which may be
            in my possession or under my control.

      5.    All the covenants herein shall inure to the benefit of the Employer,
            its successors, assigns, or designees, and shall be binding upon me,
            my heirs, executors, administrators and assigns.

      6.    This Agreement and the rights and obligations of the parties
            hereunder shall be construed, interpreted and enforced in accordance
            with, and governed by the laws of the State of Rhode Island.

      7.    I attach hereto Exhibit A, a list of all inventions, if any, which I
            developed solely or jointly with another prior to commencing
            employment with the Employer, and which are excluded from the
            operation of this Agreement, and I agree that said list is complete.

      8.    This Agreement represents the entire agreement between the Employer
            and me with respect to the subject matter hereof, superseding all
            previous oral and written communications, representations or
            agreements. This Agreement may be modified only by the express
            written agreement of both the Employer and me.

Signed and sealed this  23 day of July, 2006
