              MACK-CALI REALTY CORPORATION AUDIT COMMITTEE CHARTER

                                     PURPOSE

         There shall be an Audit Committee (the "Committee") of the Board of

(the "Company"). The primary function of the Committee is to assist the Board of
Directors in fulfilling its oversight responsibilities, primarily through: 1)
overseeing management's conduct of the Company's financial reporting process and
systems of internal accounting and financial controls; 2) monitoring the
independence and performance of the Company's outside auditors; and 3) providing
an avenue of communication among the outside auditors, management and the Board.

                            COMPOSITION AND MEETINGS

         The Committee shall have at least three (3) members at all times, each
of whom must be independent of management and the Company. Members of the
Committee shall be considered independent if: 1) in the sole discretion of the
Board, it is determined that they have no relationship that may interfere with
the exercise of their independent judgment; and 2) they meet the New York Stock
Exchange rules regarding independence of audit committee members. Members of the
Committee shall be appointed by the Board and shall serve until the earlier to

within a reasonable period of time after appointment to the Committee, and at
least one member of the Committee shall have accounting or related financial
management expertise.

         The Committee shall meet as frequently as circumstances dictate, but no
less than four times annually. The Board shall name a chairperson of the
Committee, who shall prepare and/or approve an agenda in advance of each
meeting. A majority of the members of the Committee shall constitute a quorum.

                           RESPONSIBILITIES AND DUTIES

         The Committee's principal responsibility is one of oversight. The
Company's management is responsible for preparing the Company's financial
statements and the outside auditors are responsible for auditing and/or
reviewing those financial statements. In carrying out these oversight
responsibilities, the Committee is not providing any expert or special assurance
as to the Company's financial statements or any professional

9.       MISCELLANEOUS.

         A.       EXPENSES. Borrower shall pay all of the reasonable
                  out-of-pocket expenses, including reasonable attorneys' fees,
                  incurred by Lender in connection with the enforcement of this
                  Agreement, each Pledge Agreement or in the collection of the
                  Notes.

         B.       CUMULATIVE RIGHTS AND NO WAIVER. Each and every right granted
                  to Lender under this Agreement, the Notes and each Pledge

                  in connection herewith or allowed it by law or equity, shall
                  be cumulative of and may be exercised in addition to any and
                  all other rights of Lender. No delay in exercising any right
                  shall operate as a waiver thereof, nor shall any single or
                  partial exercise by Lender of any right preclude any other or

                  by Lender, but only in writing. Except as otherwise provided

                  No notice to or demand on Borrower in any case shall, of
                  itself, entitle Borrower to any other or further notice or
                  demand in similar or other circumstances. No delay or omission
                  by Lender in exercising any power or right hereunder shall
                  impair any such right or power or be construed as a waiver
                  thereof or any acquiescence therein, nor shall any single or

                  exercise thereof, or the exercise of any other right or power
                  hereunder.

         C.       APPLICABLE LAW. This Agreement and the rights and obligations
                  of the parties hereunder shall be governed by and interpreted
                  in accordance with the laws of the State of Texas.

                  any provision of this Agreement, nor consent to any departure
                  by Borrower therefrom, shall be effective unless the same
                  shall be in writing and signed by the Lender and then shall be
                  effective only in the specific instance and for the specific
                  purpose for which given. This Agreement is binding upon
                  Borrower and his or her successors and inures to the benefit
                  of Lender and its successors and assigns.

         E.       GENDER. Words used in this Agreement of any gender shall
                  include each other gender where appropriate.

         F.       CONFLICT. In the event of any conflict between the provisions
                  of this Agreement and provisions of the Notes or each Pledge
                  Agreement, the provisions of this Agreement shall prevail.

         G.       NOTICES. Except as otherwise provided in this Agreement, any
                  notices or other communications required or permitted

                      PROMISSORY NOTE AND PLEDGE AGREEMENT

$150,000                                                          April 14, 2000

         For value received, Wyn Lewis ("Maker") hereby unconditionally promises
to pay to the order of Carreker-Antinori, Inc., a Delaware corporation ("Lender"
or "Company") the principal sum of $150,000 ("Loan Amount"), together with
interest on the unpaid balance thereof at a rate equal to 8.0%. Accrued and
unpaid interest on this Note shall be paid on May 31, 2001. The unpaid Loan
Amount will be due and payable in full on or before May 31, 2001 ("Maturity
Date"). All payments shall be made at the offices of Carreker-Antinori, Inc.,
4055 Valley View Lane, Suite 1000, Dallas, Texas 75244, or such other place as
Lender may designate in writing. Maker may prepay the outstanding Loan Amount in
whole or in part at any time without penalty. Maker shall apply any bonus
payments received from the Company, net of applicable taxes, to the Loan Amount
and accrued and unpaid interest on the Note.

         The Maker and all endorsers, sureties and guarantors of this Note
hereby jointly and severally waive demand, presentment for payment, protest,
notice of protest, notice of intent to accelerate, notice of acceleration,
diligence in collecting, the bringing of any suit against any party and any
notice of or defense on account of any extensions, renewals, or partial payments
of this Note, or any delay, indulgence or other act by any holder hereof whether
before or after maturity.

         This Note and the rights and duties of the parties hereunder shall be
governed by the laws of the State of Texas. As allowed by law, this Note is
performable by Maker in Dallas County, Texas.

         DEFAULT NOTICE AND REMEDIES. If Maker fails to perform any obligation
created by this Note or a default by Maker occurs, Lender may declare this Note
immediately due and payable in whole or in part, may enforce payment thereof and
exercise any and all of its rights and remedies hereunder or as otherwise
provided by law. Maker expressly waives presentment, demand, notice of
non-payment, notice of acceleration or other notice of any kind. Interest shall
accrue on the full amount of any overdue installments at the highest rate
permitted by law. The acceptance by Lender at any time and from time to time of
part payment on this Note shall not be deemed to be a waiver of any event of
default then existing. No waiver by Lender of any right hereunder or waiver by
Lender of any default by Maker shall operate as a waiver of any other right or
any other default.

         If Maker's employment with the Lender terminates for any reason, Lender
may declare this Note immediately due and payable in whole or in part, enforce
payment thereof, and exercise any and all of its rights and remedies hereunder.
