the Corporation outstanding as of the issuance date of this Warrant Certificate
and are subject to adjustment as provided in Section 5 of the Warrant Agreement.

         Upon surrender of this Warrant Certificate and payment of the Purchase
Price, the Corporation shall issue and cause to be delivered to the registered
holder of this Warrant Certificate a certificate for the number of shares of

reverse hereof and the further provisions of the Warrant Agreement shall for all
purposes have the same effect as if set forth fully at this place

         This Warrant Certificate and each Warrant represented hereby are issued
pursuant to and are subject in all respects to the terms and conditions set
forth in the Warrant Agreement, which is incorporated herein by reference.
Please refer to the Warrant Agreement for a description of the rights,
limitations of rights, obligations, duties and immunities hereunder of the
Transfer Agent, the Corporation and the registered holders of the Warrants. In
the event the registered holders do not comply with the terms of the Warrant
Agreement, the Warrants shall immediately become null and void.

         The Warrant Agreement provides that upon the occurrence of certain
events, the Exercise Price set forth on the face hereof may, under certain
conditions, be adjusted. If the Exercise Price is adjusted, the Warrant
Agreement provides that the Exercise Price in effect immediately prior to such
event shall be adjusted so that the registered holder of each Warrant may
receive the number of shares of Common Stock of the Corporation to which it
would have been entitled upon such action if such registered holder had so
exercised the Warrant immediately prior to the event. No fractional shares of
Common Stock will be issued upon exercise of the Warrant. If any fraction of a
share of Common Stock would be issuable upon the exercise of the Warrants (or
any specified portion thereof), the Corporation shall pay an amount in cash
equal to the product of (a) such fraction and (b) the fair market value of the
Common Stock, as determined in good faith by the Board of Directors of the
Corporation, on the Business Day prior to the date the Warrant is exercised.

         Upon surrender of this Warrant Certificate and similar Warrant
Certificates at the principal office of the Transfer Agent, by the registered
holder hereof in person or by an attorney duly authorized in writing, such
Warrant Certificates may be transferred or exchanged in the manner and subject
to the limitations provided in the Warrant Agreement, for another Warrant
Certificate or Warrant Certificates of like tenor, evidencing in the aggregate
the number of Warrants evidenced by the Warrant Certificates so surrendered and
registered in the name or names as requested by the then registered owner
thereof or by an attorney duly authorized in writing. In the case of the
exercise of less than all the Warrants represented hereby, the registered holder
shall be entitled to receive upon surrender of this Warrant Certificate another
Warrant Certificate or Warrant Certificates for the balance of the Warrants
evidenced by this Warrant Certificate

         Prior to the exercise of any Warrant represented hereby, the registered
holder shall not be entitled to any rights of a stockholder of the Corporation,
including, without limitation, the right to vote or to receive dividends or
other distributions, and shall not be entitled to receive any notice of any
proceedings of the Corporation, except as provided in the Warrant Agreement.

         The Corporation and the Transfer Agent shall treat the registered
holder as the absolute owner hereof and of each Warrant represented hereby for
all purposes and shall not be affected by any notice to the contrary.

         This Warrant Certificate shall be governed by and construed in
accordance with the laws of the State of North Carolina<PAGE>   1
                                                                    EXHIBIT 10.3

                                AMENDMENT NO . 1
                                     TO THE
                              WITNESS SYSTEMS, INC.
                    AMENDED AND RESTATED STOCK INCENTIVE PLAN

         THIS AMENDMENT NO. 1 TO THE WITNESS SYSTEMS, INC. AMENDED AND RESTATED
STOCK INCENTIVE PLAN (this "Amendment") is made effective as of the 29 day of
May, 2001, by Witness Systems, Inc., a corporation organized and existing under
the laws of the State of Delaware (the "Company").

                                   WITNESSETH:

         WHEREAS, the Company has previously adopted and currently maintains the
Witness Systems, Inc. Amended and Restated Stock Incentive Plan (the "Plan"),
under which 7,159,325 shares of Common Stock are reserved for issuance (giving
effect to a 1.8-for-1 stock split of the Common Stock effective December 27,
1999);

         WHEREAS, the Board of Directors has determined that it is in the best
interest of the Company to amend the Plan to increase the number of shares of
Common Stock reserved for issuance thereunder, subject to the approval of the
Company's shareholders;

         NOW, THEREFORE, in consideration of the premises and mutual promises
contained herein, the Plan is hereby amended as follows:

         1.       The Plan is hereby amended by deleting Section 3 of the Plan
in its entirety and substituting in lieu thereof the following:

                                   SECTION 3.
                       SHARES SUBJECT TO STOCK INCENTIVES

                  The total number of Shares that may be issued
         pursuant to Stock Incentives under this Plan shall not exceed
         Nine Million One Hundred Fifty-Nine Thousand Three Hundred
         and Twenty Five (9,159,325), plus (1) an annual amount for
         each calendar year beginning with the calendar year that
         begins on January 1, 2002, such that the total number of
         Shares reserved for issuance under this Plan will be equal to
         the sum of (A) the aggregate number of Shares previously
         issued under this Plan; (B) the aggregate number of Shares
         subject to outstanding options granted under this Plan; and
         (C) 10% of the aggregate number of Shares outstanding on the
         last day of the preceding calendar year, or (2) such lower
         amount as may be determined by the Board in its sole
         discretion; provided, however, that in no event shall the
         increase in the number of Shares from one fiscal year to the
         next exceed Three Million (3,000,000); all as adjusted
         pursuant to Section 11. Such Shares shall be reserved, to the
         extent that the Company deems appropriate, from authorized
         but unissued Shares, and from Shares which have been
         reacquired by the Company. Furthermore, any Shares subject to
         a Stock Incentive which remain after the cancellation,
         expiration or

<PAGE>   2

                  exchange of such Stock Incentive thereafter shall again
                  become available for use under this Plan, but any Surrendered
                  Shares which remain after the surrender of an ISO or a
                  non-ISO under Section 8 shall not again become available for
                  use under this Plan. Notwithstanding anything herein to the
                  contrary, no Participant may be granted Options or Stock
                  Appreciation Rights covering an aggregate number of Shares in
                  excess of one million (1,000,000) in any calendar year.

         2.       This Amendment is subject to, and shall become effective only
upon, approval thereof by the Company's stockholders.

         3.       Capitalized terms not otherwise defined herein shall have the
meaning given them in the Plan.

         4.       Except as specifically amended by this Amendment, the Plan
shall remain in full force and effect as prior to this Amendment.

         IN WITNESS WHEREOF, the Company has caused this Amendment No. 1 to the
Witness Systems, Inc. Amended and Restated Stock Incentive Plan to be executed
as of the day and year first above written.

                                       WITNESS SYSTEMS, INC.
