                                 PROXY STATEMENT
                     FOR THE ANNUAL MEETING OF STOCKHOLDERS
                           TO BE HELD ON MAY 14, 2003

                               ------------------


     The accompanying proxy is solicited on behalf of the Board of Directors
(the "Board") of Mercator Software, Inc., a Delaware corporation (the "Company"
or "Mercator"), for use at the Annual Meeting of Stockholders of the Company to
be held at the office complex located at 20 Westport Road, South Building,
Wilton, Connecticut, on Wednesday, May 14, 2003, at 9:00 a.m. Eastern Time and
any adjournments or postponements thereof (the "2003 Annual Meeting"). This
Proxy Statement and the accompanying form of proxy are being mailed to
stockholders on or about April , 2003. The Company's Annual Report on Form 10-K
for the year ended December 31, 2002, which is not part of the proxy soliciting
materials, is enclosed. Only holders of record of the Company's common stock at
the close of business on the record date for the Meeting, which is April 7,
2003, will be entitled to vote at the Meeting. A majority of the shares of
common stock outstanding on the record date will constitute a quorum for the
transaction of business at the Meeting. At the close of business on the record
date, the Company had 35,168,315 shares of common stock outstanding and entitled
to vote.


     As you may know, on March 14, 2003 a group called Strategic Software
Holdings, LLC/Broken Arrow I, L.P. ("SSH/Broken Arrow") commenced a proxy
contest by nominating a slate of directors to replace the current members of the
Board.

     Thereafter, representatives of the Company and representatives of
SSH/Broken Arrow commenced discussions about the possibility of avoiding a proxy
contest at the 2003 Annual Meeting. Such discussions continued through April 17,
2003. On April 17, 2003, the Company and SSH/Broken Arrow entered into a
settlement agreement, pursuant to which, among other things, SSH/Broken Arrow
agreed to support (and the members of the SSH/Broken Arrow group agreed to vote
all of their shares of common stock in favor of) the Company's slate of seven
nominees standing for election as directors at the 2003 Annual Meeting. Under
the settlement agreement, SSH/Broken Arrow agreed to certain "standstill"
restrictions until January 15, 2004. These restrictions prevent the members of
the SSH/Broken Arrow group from, among other things:

     o   attempting to gain control of the Board;

     o   making any "hostile" proposals to acquire the Company; and

     o   selling common stock (other than sales on the open market that do not
exceed 1% of the outstanding common stock during any 30-day period, any sale
through broker-dealers directly to principals who will not own more than 5% of
our stock after giving effect thereto and certain other specified transactions).

     The settlement agreement also provides that Rodney Bienvenu will be engaged
as a special advisor to the Board regarding the Company's strategic affairs, and
that he will make a presentation to the Board regarding the Company's strategic
affairs at the meeting of the Board to be held following the 2003 Annual Meeting
and at such other meetings of the Board prior to the termination of the
"standstill" period as the Company and Mr. Bienvenu may from time to time
thereafter mutually agree. The Company will reimburse Mr. Bienvenu for the
reasonable expenses incurred by him in traveling to such meetings plus $1,500
for each such meeting attended by him. In connection with Mr. Bienvenu's
engagement as a strategic advisor to the Board, he agreed to enter into a
non-disclosure agreement with the Company.

     Pursuant to the settlement agreement, the Company has agreed to reimburse
the SSH/Broken Arrow group for actual expenses in the amount of $300,000.

     Given the substantial costs Mercator and its stockholders would incur as
the result of continuing the proxy contest through the Annual Meeting date, and
taking into consideration the adverse impact of this matter we have seen on our
customers and partners to date, we strongly believe that this settlement is in
the best interest of all of our stockholders, as well as our customers, partners
and employees. The settlement limits the amount of money and other resources
that would otherwise be spent in waging the contest to its conclusion and it
eliminates a significant distraction to employees, customers and partners alike.
Because of the settlement, the Company can now focus exclusively on the
execution of our strategic plan to deliver value to all Mercator stakeholders.


               QUESTIONS AND ANSWERS ABOUT THE 2003 ANNUAL MEETING

HOW DO I VOTE IN PERSON?

     If you owned shares of the Company's common stock on the record date, April
7, 2003, you may attend the 2003 Annual Meeting and vote in person. If you are
not the record holder of your shares, please refer to the discussion following
the question "What if I am not the record holder of my shares?" If you hold your
shares in the name of a bank or broker, you will not be able to vote in person
at the 2003 Annual Meeting, unless you have previously specially requested and
obtained a "legal proxy" from your bank or broker and present it at the Annual
Meeting.

HOW DO I VOTE BY PROXY?

     To vote by proxy, you should complete, sign and date the enclosed proxy
card and return it promptly in the enclosed postage-paid envelope. To be able to
vote your shares in accordance with your instructions at the 2003 Annual
Meeting, we must receive your proxy as soon as possible but in any event prior
to the Annual Meeting.

WHAT IF I AM NOT THE RECORD HOLDER OF MY SHARES?


     If your shares are held in the name of a brokerage firm, bank nominee or
other institution ("Custodian"), only it can give a proxy with respect to your
shares. You may have received either a blank, executed proxy card from your
Custodian (which you can complete and send directly to the Company) or an
instruction card (which you can complete and return to the Custodian to direct
its voting of your shares). If your Custodian has not sent you either a blank,
executed proxy card or an instruction card, you may contact the Custodian
directly to provide it with instructions. If you need assistance, please contact
our solicitor, D.F. King & Co., Inc., toll-free at (800) 859-8509 (in the United
States) or (212) 269-5550 (collect, for international calls).

     If your shares are held in the name of a Custodian, and you want to vote in
person at the 2003 Annual Meeting, you may request a document called a "legal
proxy" from the Custodian and bring it to the 2003 Annual Meeting. If you need
assistance, please contact our solicitor, D.F. King & Co., Inc., toll-free at
(800) 859-8509 (in the United States) or (212) 269-5550 (collect, for
international calls).


WHAT IF I WANT TO REVOKE MY PROXY?

     If you give a proxy, you may revoke it at any time before it is voted on
your behalf. You may do so in three ways:

     -    By delivering a later-dated proxy to either our proxy solicitor, D.F.
          King & Co., Inc., or our secretary; or

     -    By delivering a written notice of revocation to either our proxy
          solicitor or our secretary; or

     -    By voting in person at the 2003 Annual Meeting.

IF I PLAN TO ATTEND THE 2003 ANNUAL MEETING, SHOULD I STILL SUBMIT A PROXY?

     Whether you plan to attend the 2003 Annual Meeting or not, we urge you to
submit a proxy card. Returning the enclosed proxy card will not affect your
right to attend the 2003 Annual Meeting and vote.

                                       2


WHO CAN VOTE?


     You are eligible to vote or to execute a proxy only if you owned shares of
the Company's common stock on the record date for the 2003 Annual Meeting, April
7, 2003. Even if you sell your shares after the record date, you will retain the
right to execute a proxy in connection with the 2003 Annual Meeting. It is
important that you grant a proxy regarding shares you held on the record date,
or vote those shares in person, even if you no longer own those shares. At the
close of business on April 7, 2003, 35,168,315 shares of the Company's common
stock were entitled to vote.


HOW MANY VOTES DO I HAVE?

     With respect to each matter to be considered at the 2003 Annual Meeting,
each stockholder will have one vote for each share of the Company's common stock
held by it on the record date. The Company has no outstanding voting securities
other than its common stock.

HOW WILL MY SHARES BE VOTED?

     If you give a proxy on the accompanying proxy card, your shares will be
voted as you direct. If you submit a proxy to us without instructions, our
representatives will vote your shares in favor of our nominees. Submitting a
proxy card will entitle our representatives to vote your shares in accordance
with their discretion on matters not described in this proxy statement that may
arise at the 2003 Annual Meeting.

     Unless a proxy specifies otherwise, it will be presumed to relate to all
shares held of record on the record date by the person who submitted it.

WHAT IS A QUORUM AND WHY IS IT NECESSARY?

     Conducting business at the 2003 Annual Meeting requires a quorum. For a
quorum to exist, stockholders representing a majority of the votes eligible to
be cast must be present in person or represented by proxy. Under the Delaware
General Corporation Law, the Company's certificate of incorporation and By-laws,
abstentions and broker non-votes are treated as present for purposes of
determining whether a quorum exists.

WHAT VOTE IS REQUIRED TO APPROVE EACH PROPOSAL AND HOW WILL VOTES BE COUNTED?

     If a quorum is present, directors will be elected by a plurality of the
votes cast. This means that the seven nominees receiving the highest number of
votes will be elected as directors.


     Broker-dealers will have discretionary authority for beneficial owners in
the election of directors. Accordingly, broker non-votes will be counted for
purposes of determining whether a quorum is present and will have the effect of
a vote for the election of each of the nominees. Stockholders do not have the
right to cumulate their votes.


     Each proposal other than the election of directors will be adopted if a
majority of the shares represented at the 2003 Annual Meeting and entitled to
vote on the proposal are voted in its favor. Accordingly, abstentions on each
such proposal will have the same effect as a vote against the proposal. Broker
non-votes will not have any effect on any such proposal.

HOW CAN I RECEIVE MORE INFORMATION?


     If you have any questions about giving your proxy or about our
solicitation, or if you require assistance, please call D.F. King & Co., Inc.,
toll-free at (800) 859-8509 (in the United States) or (212) 269-5550 (collect,
for international calls).

                     PROPOSAL NO. 1 -- ELECTION OF DIRECTORS

     The Board currently consists of seven directors, all of whom are nominated
for election at the 2003 Annual Meeting. Each director will be elected to serve
until the next annual meeting of stockholders and until his or her successor is
duly elected and qualified or until such director's earlier resignation, death
or removal.

     Shares represented by the accompanying proxy will be voted "for" the
election of the seven nominees recommended by the Board unless the proxy is
marked in such a manner as to withhold authority so to vote. In the event that
any nominee for any reason is unable to or will not serve, the proxies may be
voted for such substitute nominee as the proxy holders may determine. The
Company is not aware of any nominee who will be unable to or will not serve as a
director.

     Directors will be elected by a plurality of the votes present in person or
represented by proxy at the 2003 Annual Meeting and entitled to vote in the
election of directors. The seven nominees for election of directors who receive
the greatest number of votes cast for the election of directors at the 2003
Annual Meeting will become directors at the conclusion of the tabulation of
votes.

BOARD OF DIRECTORS MEETINGS AND COMMITTEES

     BOARD OF DIRECTORS

     The Board of Directors has standing Audit, Compensation and Stock Option
Committees. The Board of Directors does not have a nominating committee or a
committee performing similar functions, but has in the past performed such
functions itself.

     During 2002, the Board met nine times. Diane Baker, who resigned as a
director on February 13, 2002, attended no meetings during 2002.

     AUDIT COMMITTEE

     The Audit Committee is comprised of Messrs. Lehman (Chairman), Keet and
Sisco, all of whom are independent (as independence is defined in Rule
4200(a)(14) of the Nasdaq Marketplace Rules). The Audit Committee met 10 times
during 2002. The Audit Committee meets with the Company's independent
accountants to review the adequacy of the Company's internal control systems and
financial reporting procedures; reviews the general scope of the Company's
annual audit and the fees charged by the independent accountants; reviews and
monitors the performance of non-audit services by the Company's independent
accountants; reviews the fairness of any proposed transaction between the
Company and any officer, director or other affiliate of the Company (other than
transactions subject to the review of the Compensation Committee), and after
such review, makes recommendations to the full Board; and performs such further
functions as may be required by the Nasdaq National Market, on which the
Company's common stock is listed.


     Ms. Baker, Chairperson of the Audit Committee in 2001, resigned from the
Board and the Audit Committee in February 2002. Accordingly, in view of the
Company's need for an immediate replacement for Ms. Baker and its inability to
locate a new Audit Committee member on short notice, and under such limited and
exceptional circumstances, the Board appointed Mr. Schadt as interim Chairman of
the Audit Committee for the period from February 2002 until April 2002 based on
his knowledge and experience in financial matters. Mr. Schadt is not
"independent" as that term is defined in Rule 4200(a)(14) of the Nasdaq
Marketplace Rules because he was employed by the Company as Chairman of the
Board and interim Chief Executive Officer within the past three years. In April
2002, the Board elected Michael E. Lehman as a Director and as Chairman of the
Audit Committee to replace Mr. Schadt.


     COMPENSATION COMMITTEE

     Messrs. Schadt (Chairman), Sisco and Stevens comprise the Compensation
Committee. During 2002, the Compensation Committee met eight times. The
Compensation Committee recommends compensation for officers and key employees of
the Company.

     STOCK OPTION COMMITTEE

     Messrs. Stevens (Chairman) and Sisco comprise the Stock Option Committee.
Messrs. Stevens and Sisco are non-employee directors within the meaning of
Section 16 of the Securities Exchange Act of 1934, as amended ("Exchange Act"),
and Messrs. Stevens and Sisco are "outside directors" within the meaning of
Section 162(m) of the Internal Revenue Code of 1986, as amended (the "Code").
Neither of the members of the Stock Option Committee has any interlocking
relationships as defined by the Securities and Exchange Commission ("SEC").
During 2002, the Stock Option Committee met four times. The Stock Option
Committee is authorized to administer the Company's equity compensation plans
(other than the 1997 Directors Stock Option Plan) including granting stock
options and awarding restricted stock and stock bonuses pursuant to such plans.
The President/Chief Executive Officer has been delegated authority to grant
limited stock options to persons who are not subject to Section 16 of the
Exchange Act.

                                        8


                             AUDIT COMMITTEE REPORT

     The Audit Committee is presently comprised of Messrs. Lehman, Keet and
Sisco, all of whom have been determined to be independent as defined by the
Nasdaq Marketplace Rules. None of the members of the Audit Committee have a
relationship with the Company or its subsidiaries, which would interfere with
that Audit Committee member's exercise of independent judgment in carrying out
the responsibility of a director. In 2001, the Audit Committee adopted a written
charter which has been approved by the Board of Directors and was set forth as
an exhibit to the Company's proxy statement for the 2001 Annual Meeting of
Stockholders. That charter is currently in effect. The Audit Committee has
fulfilled its responsibilities and duties as set forth in the written charter.

     The Audit Committee has reviewed and discussed the Company's audited
financial statements with management, which has primary responsibility for the
financial statements. KPMG LLP ("KPMG"), the Company's independent accountants
for 2002, is responsible for expressing an opinion on the conformity of the
Company's audited financial statements with accounting principles generally
accepted in the United States of America.

     The Audit Committee has discussed with KPMG the matters that are required
to be discussed by Statement on Auditing Standards No. 61 (Communication with
Audit Committees), as modified or supplemented. The Audit Committee has received
from KPMG the written disclosures and the letter required by Independence
Standards Board Standard No. 1 (Independence Discussions with Audit Committees),
as modified or supplemented, and the Audit Committee discussed and affirmed the
independence of KPMG from management and the Company. The Audit Committee has
received the reports of the Chief Executive Officer and the Chief Financial
Officer relating to their evaluation of the Company's internal controls. The
Audit Committee also considered whether KPMG's provision of non-audit services
(including those services included under the caption "All Other Fees") is
compatible with maintaining KPMG's independence.

     Based on the review and discussions referred to above, and additional
matters deemed relevant and appropriate by the Audit Committee, the Audit
Committee recommended to the Board of Directors that the audited financial
statements be included in the Company's Annual Report on Form 10-K for 2002 and
that KPMG be appointed independent accountants for the Company for 2003.

     This report is provided by the following directors who constitute the Audit
Committee:

                           Michael E. Lehman, Chairman
                                 Ernest E. Keet
                                 Dennis G. Sisco

INDEPENDENT ACCOUNTANTS FEES

     In addition to retaining KPMG to audit the Company's consolidated financial
statements for 2002, the Company retained KPMG to provide various non-audit
services in 2002, and expects to continue to do so in the future. The aggregate
fees billed for professional services by KPMG in 2002 for these various services
were:

     Audit Fees: $613,000 for professional services rendered for the audit of
the Company's consolidated financial statements for 2002 and the quarterly
reviews of the financial statements included in the Company's Quarterly Reports
on Form 10-Q for 2002.

     Financial Information Systems Design and Implementation Fees: $0.

     All Other Fees: $388,000 for tax services including tax return preparation
and tax planning, and $125,000 primarily for the audit of the Company's 401(k)
benefit plan and other accounting advice and assistance.

     Although the Company expects to continue to retain KPMG for audit and other
services, the Company's managers are responsible for establishing and
maintaining the Company's system of internal accounting controls.

                          COMPENSATION COMMITTEE REPORT


     The Compensation Committee of the Board (the "Compensation Committee")
oversees Mercator's executive compensation program. The Compensation Committee
has three members: James P. Schadt, Chairman, Dennis G. Sisco and Mark C.
Stevens. Messrs. Sisco and Stevens are non-employee directors within the meaning
of Section 16 of the Exchange Act, and are "outside directors" within the
meaning of Section 162(m) of the Code. None of the members of the Compensation
Committee has any interlocking relationships as defined by the SEC.

GENERAL COMPENSATION PHILOSOPHY

     The primary function of the Compensation Committee is to assist the Board
of Directors in fulfilling its responsibilities of establishing the general
compensation policy of the Company by (i) reviewing base salary levels and
target bonuses for the Chief Executive Officer ("CEO") and other executive
officers and key employees of the Company, and (ii) overseeing the Company's
incentive and equity plans together with the Company's Stock Option Committee.
The Compensation Committee typically reviews base salary levels and target
bonuses for the CEO and other executive officers and key employees of the
Company at or about the beginning of each year, based on input from, and
information compiled by, management. In addition to their base salaries, the
Company's executive officers, including the CEO, and key employees, are each
eligible to receive a cash bonus pursuant to a management incentive plan and are
entitled to participate in the 1997 Equity Incentive Plan.

     The Company's compensation policy for executive officers and key employees
is to relate compensation directly to corporate performance and stockholder
value. The Compensation Committee establishes the Company's compensation
policies applicable to the executive officers and key employees, including the
CEO, and evaluates the performance of such persons. The Compensation Committee
has adopted the following guidelines for compensation decisions:


     o    provide a competitive total compensation package that enables the
          Company to attract and retain key executive talent;

     o    align all pay programs with the Company's annual and long-term
          business strategies and objectives; and

     o    provide variable compensation opportunities that are directly linked
          to the performance of the Company and that link executive reward to
          stockholder return.


     The Company's compensation policy relates a portion of each individual's
total compensation to Company-wide and individual objectives based on corporate
performance goals set forth at the beginning of the year.

     The base salaries and incentive compensation of the executive officers are
determined by the Compensation Committee, and stock option grants to executive
officers are determined by the Stock Option Committee, in part by reviewing data
on prevailing compensation practices in companies with whom the Company competes
for executive talent, and by evaluating such information in connection with the
Company's corporate goals. In certain extraordinary circumstances, the
Compensation Committee may review and make recommendations with respect to stock
options. In order to determine base salary, target bonuses and total target cash
compensation, the Compensation Committee, in consultation with management, also
reviews general market conditions, compensation history of the candidate, and
compares the compensation of the Company's executive officers and key employees
with the compensation packages of similarly situated executives and employees at
comparable companies.

2002 EXECUTIVE COMPENSATION

     BASE SALARY


     In order to evaluate Mercator's competitive position in the industry, the
Compensation Committee reviewed and analyzed the compensation packages,
including base salary levels offered by other software companies that we believe
to be in our peer group, including companies such as SeeBeyond Technology
Corporation, Tibco Software Inc., Vitria


                                       10



Technology, Inc., and Webmethods, Inc. In reviewing the compensation packages
offered by these other companies, the Compensation Committee examined a variety
of factors, including their relative size, performance and operational goals.
With respect to our corporate executive officers, other than the CEO, the
Compensation Committee also has considered other factors, such as each
executive's scope of responsibility, performance, prior experience and salary
history, as well as the compensation packages of other executives at Mercator.
The Compensation Committee initially targeted above the mid-market level of the
industry competitive base salary range and made adjustments (or not) based on
these other factors to arrive at base salary for the year. No specific fixed
weighting or formula was applied to these factors in determining base salary.
Rather, the Compensation Committee exercised its judgment in evaluating these
factors and in determining the appropriate base salary.

     Our executives' base salaries are generally at or above those of executives
at companies in our peer group. Most of our current management was hired by the
Board early in 2001 to effect a turn-around of the Company. The executives we
hired were, in certain instances, paid above the 50th percentile of our peer
group in order to compensate them for increased risk and uncertainty in taking
on the challenges facing Mercator. Additionally, many executives at companies in
our peer group had been at their companies for a relatively long period of time
and, accordingly, their total compensation packages had a significant portion of
non-cash (i.e., stock or option-based) compensation. In lieu of significant
beneficial ownership for our new management, the Compensation Committee
determined in certain instances to provide total compensation packages with
relatively higher levels of cash compensation (both salary and bonus
opportunity) to reward a successful turn-around. Additionally, at the time these
executives were hired, the perceived value of equity-based compensation had
declined due to prevailing market conditions.


     INCENTIVE AWARDS


     In 2002, unless covered by an employment agreement, senior level managers
of the Company, including executive officers, were eligible to receive an annual
performance-based bonus based upon (i) the financial goals of the Company, as
determined by the Compensation Committee, and (ii) the employee's achievement of
other objectives as determined by the Compensation Committee. As discussed
above, the Compensation Committee also reviewed the bonus packages offered by
the other members of our peer group, targeting above the mid-market level of the
industry competitive bonus range if all operational and strategic targets are
achieved, and then examined other factors to determine the aggregate bonus
opportunity offered to our executives. The Compensation Committee has the
discretion to determine: the individuals who are to receive performance-based
bonuses; the amount of the bonus; the weighting between the Company's financial
goals and other corporate objectives when determining an individual's
performance-based bonus; and whether to revise performance-based bonus amounts
and targets during the year if market conditions warrant.

     In 2002, each executive was eligible to receive a performance-based bonus
of up to 100% of their base salary if the Company achieved pre-determined
operational targets (e.g., revenue and EBITDA) and strategic targets (e.g.,
license revenues from partners and market capitalization). A portion of the
bonus was then earned for each target that was achieved. As discussed above,
each executive also had individual objectives. The original performance-based
bonus pool at 100% achievement of objectives would have paid $2.3 million to the
Company's executives. Based on the Company's performance relative to the revised
targets in 2002, the Company instead paid $1.1 million in bonuses.


     LONG-TERM INCENTIVE AWARDS

     The Compensation Committee believes that equity-based compensation in the
form of stock options links the interests of management and the Company's
stockholders by focusing employees and management on increasing stockholder
value. Stock options generally have value only if the price of the Company's
stock increases above the fair market value on the grant date and the option
grantee remains in the Company's employ for the period required for the shares
to vest.

     CHIEF EXECUTIVE OFFICER COMPENSATION

     The Compensation Committee, together with the Board of Directors, will also
subjectively evaluate the level of performance of the CEO to determine current
and future appropriate base pay levels. For the CEO, the Compensation Committee
has in prior years targeted above the mid-market level of the base salary range
determined by its aforementioned competitive analysis, and has given significant
emphasis to annual bonus and longer-term

                                       11


incentives for Mr. King's total compensation package. For fiscal year 2002, Mr.
King's base salary was $400,000. Total compensation paid in 2002 was $410,192 in
salary and $200,000 in bonus, with additional compensation in the form of
long-term incentive awards as described above. The additional $10,192 in salary
was due to a payroll change from bi-weekly to semi-monthly resulting in an
additional payroll for all employees for the period from December 21, 2002 to
December 31, 2002.


     Mr. King's arrangements were determined in a manner consistent with the
factors described above for all executive officers and with available market
data as to competitive compensation terms. In January 2002, Mr. King's base
salary was increased from $375,000 to $400,000 in recognition of, among other
things, a significant increase in the Company's market capitalization during his
tenure through that date. His bonus compensation was determined based on his
achievement of certain operating targets (revenue and EBITDA) and certain
strategic targets (license revenue, revenue influenced by partners and market
capitalization). Mr. King has not received a base salary increase in 2003.


     Mr. King did not participate in any compensation deliberations of the
Board, the Compensation Committee or the Stock Option Committee with respect to
any of his compensation. The Committee considered this compensation package
appropriate in view of Mr. King's effectiveness in management and cost-cutting
measures of the Company in an unusually challenging global economic environment.

     INTERNAL REVENUE CODE SECTION 162(M) LIMITATION

     In general, under Section 162(m) of the Code, the Company cannot deduct,
for federal income tax purposes, compensation in excess of $1,000,000 paid to
certain executive officers. This deduction limitation does not apply, however,
to compensation that constitutes "qualified performance-based compensation"
within the meaning of Section 162(m) of the Code and the regulations promulgated
thereunder. The Company has considered the limitations on deductions imposed by
Section 162(m) of the Code and it is the Company's present intention, for so

                          STOCK OPTION COMMITTEE REPORT


     In 2002, stock options were granted in accordance with the Company's 1997
Equity Incentive Plan to certain executive officers and key employees as
incentives for them to become employees or to aid in their retention and to
align their interests with those of the stockholders. Stock options typically
have been granted to executive officers when the executive first joins the
Company, in connection with a significant change in responsibilities and, in
certain cases, to achieve equity within a peer group. The Stock Option Committee
may grant stock options to retain executive officers and key employees in order
to strive to increase the value of the Company's common stock. The number of
shares subject to each stock option granted is within the discretion of the
Stock Option Committee and is based on anticipated future contribution and
ability to impact the Company's results, past performance or consistency within
the grantee's peer group. In 2002, the Stock Option Committee considered these
factors, as well as the number of unvested option shares held by the grantee as
of the date of grant. The stock options generally become exercisable over a
four-year period and are granted at a price that is equal to the fair market
value of the Company's common stock on the date of grant.

     In January 2002, the Stock Option Committee granted Mr. King, the Company's
Chairman of the Board of Directors, Chief Executive Officer and President,
300,000 options. The Stock Option Committee's determination to grant such stock
options was based on Company performance in 2001 (and that such performance was
the result of his contributions) and the significant increase in market
valuation realized by the Company and to provide a significant incentive for him
to enhance long-term stockholder value. Additionally, the Board considered stock
ownership of chief executive officers at other companies in Mercator's peer
group.

     The Company also granted other executives stock options in January 2002
based on Company performance in 2001. In December 2002, in light of the
significant industry-wide decrease in the market valuation of technology
companies (which, in many cases, resulted in a corresponding decline in value of
stock options previously granted) the decision was made to provide additional
options for purposes of motivation and retention, to a broad list of employees,
whose present and potential contributions were considered to be important to the
success of the Company during the current challenging business period. These
grants, made in December 2002, are intended to cover grants through and
including December 31, 2004 (effectively covering two years of grants). This was
deemed necessary and appropriate in light of the Company's recently-undertaken
workforce reduction and the other factors mentioned above. The Board approved
the proposed option grants stipulating no further grants would be made to
existing employees for 2003 or 2004 unless specifically approved by the Stock
Option Committee in connection with a promotion or other extraordinary
circumstances.


     This report is provided by the following directors who constitute the Stock
Option Committee:

                            Mark C. Stevens, Chairman
                                 Dennis G. Sisco

     OPTION GRANTS IN 2002

     The following table sets forth information regarding option grants during
2002 pursuant to the Company's 1997 Equity Incentive Plan (the "1997 Plan") to
each of the Named Executive Officers. The table sets forth the hypothetical
gains or "option spreads" that would exist for the options at the end of their
respective ten-year terms. These gains are based on assumed rates of annual
compound stock price appreciation of 5% and 10% from the date the option was
granted to the end of the option term, as required by applicable SEC rules. They
do not represent the Company's estimate or projection of future common stock
price or value.

COMPANY STOCK PRICE PERFORMANCE

     The stock price performance graph below is required by the SEC and shall
not be deemed to be incorporated by reference by any general statement
incorporating by reference this Proxy Statement into any filing under the
Securities Act of 1933, as amended, or under the Securities Exchange Act of
1934, as amended, except to the extent that the Company specifically
incorporates this information by reference, and shall not otherwise be deemed
soliciting material or filed under such Acts.


     The graph below compares the cumulative total stockholder return on the
common stock of the Company from July 3, 1997 to December 31, 2002 with the
cumulative total return on the Nasdaq Stock Market -- U.S. Index, the J.P.
Morgan H&Q Index ("H&Q Index") and the RDG Software Composite ("RDG Index") over
the same period (assuming the investment of $100 in the common stock of Company
and in each of the other indices on July 3, 1997, and reinvestment of all
dividends, if any). The Company used the H&Q Index as its published line of
business index in preparing this performance graph until J.P. Morgan stopped
publishing the H&Q Index effective February 2002. The H&Q Index has been
replaced by the RDG Index, which is similar in components to the H&Q Index.

     PROPOSAL NO. 2 -- RATIFICATION OF SELECTION OF INDEPENDENT ACCOUNTANTS

     The Company has selected KPMG LLP ("KPMG") as its independent accountants
to perform the audit of the Company's financial statements for 2003, and the
stockholders are being asked to ratify such selection. KPMG was engaged as the
Company's independent accountants for the year ended December 31, 2002.
Representatives of KPMG will be present at the Meeting, will have the
opportunity to make a statement at the 2003 Annual Meeting if they desire to do
so, and will be available to respond to appropriate questions.

     The affirmative vote of a majority of the shares of common stock present in
person or represented by proxy at the 2003 Annual Meeting and entitled to vote
on the proposal is required to approve the ratification of selection of
independent accountants.

                THE BOARD RECOMMENDS A VOTE FOR THE RATIFICATION
                          OF THE SELECTION OF KPMG LLP.
