of Ascential Software Corporation, a Delaware corporation ("Ascential") and its

     On August 2, 2003, Mercator entered into an Agreement and Plan of Merger
with Ascential and Purchaser (the "Merger Agreement"), pursuant to which, on
August 8, 2003, Purchaser commenced a tender offer to purchase all outstanding
shares of Mercator Common Stock (including the associated preferred stock
purchase rights, which together with the Mercator Common Stock are referred to
herein as the "Shares") at $3.00 per share, net to the seller in cash, without
interest thereon, upon the terms and conditions set forth in the Offer to
Purchase, dated August 8, 2003, and in the related Letter of Transmittal (which
together with any amendments or supplements thereto, collectively constitute the
"Offer"). Copies of the Offer to Purchase and the Letter of Transmittal were
mailed to stockholders of Mercator on or about August 8, 2003 and are filed as
exhibits (a)(1)(A) and (a)(1)(B), respectively, to the Tender Offer Statement on
Schedule TO (as amended and supplemented from time to time, the "Schedule TO")
which was initially filed by Ascential and Purchaser with the Securities and
Exchange Commission on August 8, 2003. Pursuant to the Merger Agreement,
Purchaser commenced the Offer on August 8, 2003. The Offer and the withdrawal
rights are currently scheduled to expire at 11:59 p.m., New York City time, on
September 8, 2003, unless Purchaser extends the period of time for which the
Offer is open in accordance with the terms of the Merger Agreement. Any
extension will be publicly announced by a press release issued to the Dow Jones
News Service no later than 9:00 a.m. New York City time, on the next business
day following the scheduled expiration date.

     The Merger Agreement provides, subject to the satisfaction or waiver of
certain conditions, including regulatory approvals, that following the date on
which Purchaser accepts for payment all Shares validly tendered and not
withdrawn pursuant to the Offer, subject to the terms and conditions of the
Offer, including there being validly tendered and not withdrawn prior to the
expiration of the Offer that number of Shares which represent at least 51% of
the shares of Mercator Common Stock on a fully diluted basis, and in accordance
with the Delaware General Corporation Law (the "DGCL"), Purchaser will be merged
with and into Mercator (the "Merger") with Mercator surviving as a wholly owned
subsidiary of Ascential. At the effective time of the Merger, each Share issued
and outstanding immediately prior to the effective time (other than Shares owned
by (i) Mercator, Ascential or Purchaser or any of their respective subsidiaries
or (ii) stockholders who perfect their dissenters' rights under the DGCL) will
be converted into the right to receive the same amount of cash, without
interest, that is being paid pursuant to the Offer.

     This Information Statement is being mailed to you in accordance with
Section 14(f) of the Securities Exchange Act of 1934, as amended, and Rule 14f-l
promulgated thereunder. The information set forth herein supplements certain
information set forth in the Schedule 14D-9.

                                        1


     The Offer, the Merger and the Merger Agreement are more fully described in
the Offer to Purchase and the Letter of Transmittal, each of which were mailed
to stockholders of Mercator on or about August 8, 2003, and the Schedule 14D-9
which was initially mailed to stockholders of Mercator on or about August 8,
2003 and an amendment thereto which is being mailed herewith.

                                    GENERAL

     Mercator Common Stock is the only class of equity securities that is
currently outstanding and entitled to vote at a meeting of Mercator's
stockholders. Each share of Mercator Common Stock is entitled to one vote. As of
August 11, 2003, there were 35,898,791 shares of Mercator Common Stock
outstanding. As of the date hereof, neither Ascential or Purchaser held of
record any shares of Mercator Common Stock. However, as a result of the
transactions contemplated by the Stock Tender Agreement (as defined below) and
the Option Agreement (as defined below), Ascential and Purchaser are deemed to
beneficially own 5,910,134 and 12,959,995 shares of Mercator Common Stock,
respectively. Both Ascential and Purchaser disclaim such beneficial ownership.

             RIGHTS TO DESIGNATE DIRECTORS AND ASCENTIAL DESIGNEES

     The Merger Agreement provides that, upon the purchase of Shares pursuant to
the Offer and from time to time thereafter, Ascential will be entitled to
designate such number of directors, rounded up to the next whole number, on the
Board as is equal to the product of the total number of directors on the Board
(including the directors designated by Ascential) multiplied by a fraction, the
numerator of which equals the number of Shares beneficially owned by Ascential
and its subsidiaries (including Purchaser) and the denominator of which equals
the total number of Shares then outstanding. Mercator will take such actions as
are necessary to cause such persons designated by Ascential to be appointed or
elected to the Board, including amending Mercator's bylaws, increasing the
number of directors on the Board and obtaining resignations of a number of
incumbent directors, or all of them, as is necessary to enable Ascential's
designees to be so elected or appointed.

     The Merger Agreement also provides that in the event that Ascential's
designees are elected or appointed to the Board, until the effective time of the
Merger, the Board will have at least two directors who are not stockholders or
affiliates of Ascential or Purchaser and are otherwise considered independent
directors within the meaning of the rules of the Nasdaq Stock Market, Inc.
("Independent Directors"). The Independent Directors will have the sole power
and authority, by a majority vote of such Independent Directors, from the
acceptance for payment of Shares pursuant to the Offer and prior to the
effective time of the Merger, to: (i) amend or terminate the Merger Agreement by
Mercator; (ii) exercise or waive any of Mercator's rights, benefits or remedies
under the Merger Agreement; or (iii) take any other action under or in
connection with the Merger Agreement if such action materially and adversely
affects holders of Shares other than Ascential or Purchaser.

     Ascential will select its designees from among the individuals listed below
(the "Ascential Designees"). Each of the following individuals has consented to
serve as a director of Mercator if appointed or elected. Ascential has advised
Mercator that to its knowledge none of the Ascential Designees or any of their
affiliates beneficially owns any equity securities or rights to acquire any such
securities of Mercator, nor has any such person been involved in any transaction
with Mercator or any of its directors, executive officers or affiliates that is
required to be disclosed pursuant to the rules and regulations of the SEC other
than with respect to transactions between Ascential and Mercator that have been
described herein, in the Schedule TO or the Schedule 14D-9. In addition,
Ascential has advised Mercator that to its knowledge none of the Ascential
Designees is currently a director of, or holds any position with, Mercator nor
has a familial relationship with any director or executive officer of Mercator,
or with any other Ascential Designee.

COMPENSATION OF DIRECTORS

     Mercator reimburses its directors for reasonable expenses associated with
their attendance at Board and committee meetings. Directors who are not
employees also receive cash compensation as follows: (a) an annual retainer of
$15,000, (b) $1,500 per Board meeting attended and (c) $500 per committee
meeting attended. Directors are eligible to participate in Mercator's 1997
Directors Stock Option Plan (the "Directors Plan") and the 1997 Equity Incentive
Plan (the "1997 Plan"). In December 2002, the Board revised the annual option
grant compensation to: (a) 50,000 options as an initial grant for new directors,
(b) 20,000 options each year for continuing directors and (c) 3,000 option
grants for chairpersons of the Board committees. This revision had the effect of
increasing the annual grant by 10,000 options retroactive to the 2002 grants.
The Board also accelerated the 2003 grant to be issued in December 2002 thereby
giving each continuing director a total of 30,000 options in December 2002.
During 2002, the following stock options to purchase shares of Mercator Common
Stock were granted to non-employee directors under the Directors Plan and the
1997 Plan: Constance Galley received an option grant under the Directors Plan to
purchase 10,000 shares at an exercise price of $1.50 per share and an option
grant under the 1997 Plan to purchase 30,000 shares at an exercise price of
$0.94 per share; Ernest Keet received an option grant under the Directors Plan
to purchase 10,000 shares at an exercise price of $1.50 and an option grant
under the 1997 Plan to purchase 30,000 shares at an exercise price of $0.94 per
share; Michael Lehman received three option grants under the Directors Plan to
purchase, in the aggregate, 70,000 shares at an exercise price of $3.60 per
share and 3,000 shares at an exercise price of $1.50 per share, and an option
grant under the 1997 Plan to purchase 30,000 shares at an exercise price of
$0.94 per share; James Schadt received two option grants under the Directors
Plan to purchase a total of 13,000 shares at an exercise price of $1.50 per
share and an option grant under the 1997 Plan to purchase 30,000 shares at an
exercise price of $0.94 per share; Dennis Sisco received an option grant under
the Directors Plan to purchase 10,000 shares at an exercise price of $1.50 per
share and an option grant under the 1997 Plan to purchase 30,000 shares at an
exercise price of $0.94 per share; and Mark Stevens received two option grants
under the Directors Plan to purchase a total of 13,000 shares at an exercise
price of $1.50 per share and an option grant under the 1997 Plan to purchase
30,000 shares at an exercise price of $0.94 per share.

     During March 2003, the Board determined that two of its members, Messrs.
Sisco and Stevens, should provide management with advice and oversight during
the proxy contest and in connection with Mercator's evaluation of strategic
alternatives and should keep the Board informed about the proxy contest and such
evaluation. As compensation for providing such advice and oversight, Mercator
agreed to pay Mr. Sisco $3,500 per week during the proxy contest and $1,750 per
week thereafter and agreed to pay Mr. Stevens $6,500 per week during the proxy
contest and $3,250 per week thereafter. At the time the Board assigned these
tasks to Messrs. Sisco and Stevens, it was expected that the assignment would
end before the end of June 2003. However, Mercator's evaluation of strategic
alternatives lasted longer than originally anticipated and, as of August 11,
2003, Messrs. Sisco and Stevens had earned approximately $40,000 and $73,000,
respectively, for their services. They are also reimbursed for all out-of-pocket
expenses they incur in connection with such services.

BOARD OF DIRECTORS AND COMMITTEES

     Board of Directors.  The Board has standing Audit, Compensation and Stock
Option Committees. The Board 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)(15) of the Nasdaq Marketplace Rules). The Audit
Committee met 10 times during 2002. The Audit Committee meets with Mercator's
independent accountants to review the adequacy of Mercator's internal control
systems and financial reporting procedures, reviews the general scope of
Mercator's annual audit and the fees charged by

                                        7


the independent accountants, reviews and monitors the performance of non-audit
services by Mercator's independent accountants, reviews the fairness of any
proposed transaction between Mercator and any officer, director or other
affiliate of Mercator (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 Mercator Common Stock is listed.

     Ms. Baker, former chairperson of the Audit Committee in 2001, resigned from
the Board and the Audit Committee in February 2002. Accordingly, in view of
Mercator'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)(15) of the Nasdaq
Marketplace Rules because he was employed by Mercator 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 Mercator.

     Compensation Committee Interlocks and Insider Participation.  Mr. Schadt, a
member of Mercator's Compensation Committee, was a former officer of Mercator.
He held the position of interim Chairman and Chief Executive Officer of Mercator
from November 2000 to May 2001. Mr. Schadt's son-in-law is the chief executive
officer of Harvard Pilgrim Health Care, with whom Mercator has entered into a
license agreement described under "Certain Relationships and Related
Transactions" on page 21. Messrs. Sisco and Stevens, who are also members of the
Compensation Committee, have no interlocking relationships as defined by the
SEC.

     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. During 2002, the Stock Option Committee met four times. The Stock
Option Committee is authorized to administer Mercator'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.

                         SECURITY OWNERSHIP OF CERTAIN

STOCK TENDER AGREEMENT

     Ascential and Purchaser have entered into a Stock Tender Agreement, dated

of Ernest E. Keet, Roy C. King, Constance F. Galley, James P. Schadt, Dennis G.

Mark W. Register, Thracy P. Varvoglis, Jill M. Donohoe, Michael J. Collins,
David L. Goret, Ronald R. Smith and Greg O'Brien, as stockholders and option
holders of Mercator (each a "Stockholder" and collectively, the "Stockholders").
Pursuant to the Stock Tender Agreement, each Stockholder has: (i) agreed to
tender such Stockholder's Individual Shares (as defined in the Stock Tender
Agreement)

                                        10


promptly after Purchaser commences the Offer; and (ii) appointed Peter Fiore,
Scott Semel and Robert McBride, as officers of Purchaser, an irrevocable proxy
(A) to vote the Stockholders' Individual Shares in favor of the Merger and the
Merger Agreement and (B) vote against any action or agreement that is contrary
to the Merger Agreement or the Stock Tender Agreement, or that would materially
change Mercator's corporate structure or business. The Stock Tender Agreement
also gives Ascential an option to acquire all the Individual Shares at a
purchase price per share equal to the Offer Price (or such higher price as may
be offered by Purchaser in the Offer), exercisable only if the Stockholders fail
to comply with the Stock Tender Agreement, or if the Stockholders withdraw their
tender of shares of Mercator Common Stock made pursuant to the Offer.

     As of August 11, 2003, Mercator's directors, executive officers and
officers that entered into the Stock Tender Agreement owned an aggregate of

option to purchase from Mercator not more than 19.99% of the then outstanding
shares of Mercator Common Stock, at a price per share of Mercator Common Stock
equal to $3.00. This option is exercisable by Purchaser only after the
acceptance of and payment for shares of Mercator Common Stock pursuant to the
Offer, and it is also conditioned upon Purchaser owning at least 90% of the
outstanding shares of Mercator Common Stock immediately following the exercise
of the option. The portion of the purchase price owing upon exercise of such
option will be equal to the product of (i) the number of shares of Mercator
Common Stock purchased pursuant to such option multiplied by (ii) the par value
per share will be paid to Mercator in cash, and the balance of the purchase
price will be paid by delivery to Mercator of a non-interest bearing unsecured
demand note from Purchaser that is guaranteed by Ascential. Such option may be
exercised on two day's written notice given by Purchaser to Mercator.

     A summary of the Option Agreement was provided in the Schedule 14D-9 and a
copy of the Option Agreement was attached as exhibit (e)(2) thereto.

                         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
in fulfilling its responsibilities of establishing the general compensation
policy of Mercator by (i) reviewing base salary levels and target bonuses for
the Chief Executive Officer ("CEO") and other executive officers and key
employees of Mercator, and (ii) overseeing Mercator's incentive and equity plans
together with Mercator'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 Mercator at or about the beginning of
each year, based on input from, and information compiled by, management. In
addition to their base salaries, Mercator'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.

     Mercator's compensation policy for executive officers and key employees is
to relate compensation directly to corporate performance and stockholder value.
The Compensation Committee establishes Mercator'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:

     - provide a competitive total compensation package that enables Mercator to
       attract and retain key executive talent;

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

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

     Mercator'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 Mercator competes
for executive talent, and by evaluating such information in connection with
Mercator'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
                                        13


conditions, compensation history of the candidate, and compares the compensation
of Mercator'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 reviews and analyzes 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 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.

     The base salaries of Mercator's executives are generally at or above those
of executives at companies in Mercator's peer group. There are two reasons for
this. First, most of Mercator's current management was hired by the Board early
in 2001 to effect a turn-around of Mercator. The people Mercator hired were, in
some instances, paid above the 50th percentile of Mercator's peer group in order
to compensate them for increased risk and uncertainty in taking on the
challenges facing Mercator. Second, the compensation of many executives at
companies in Mercator's 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 compensation. In lieu of significant beneficial
ownership for Mercator's new management, the Compensation Committee determined
to provide total compensation packages with relatively higher levels of cash
compensation (both salary and bonus opportunity) to reward a successful
turn-around.

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

     In 2002, each executive was eligible to receive a bonus of up to 100% of
their base salary if Mercator achieved pre-determined strategic targets (e.g.,
license revenues from partners and market capitalization) and operational
targets (e.g., revenue and EBITDA). A portion of the bonus was then earned if
for each target that is achieved. As discussed above, each executive also had
individual objectives. The original bonus pool at 100% achievement of objectives
would have paid $2.3 million to Mercator's executives. Based on Mercator's
performance relative to the revised targets in 2002, Mercator instead paid $1.0
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 Mercator's stockholders by focusing employees and management on
increasing stockholder value. Stock options generally have value only if the
price of Mercator's stock increases above the fair market value on the grant
date and the option grantee remains in Mercator's employ for the period required
for the shares to vest.

                                        14


     Chief Executive Officer Compensation.  The Compensation Committee, together
with the Board, also subjectively evaluates 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 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 Mercator'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 Mercator in an unusually challenging global economic environment.

     Internal Revenue Code Section 162(m) Limitation.  In general, under Section
162(m) of the Code, Mercator 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. Mercator has considered
the limitations on deductions imposed by Section 162(m) of the Code and it is
Mercator's present intention, for so long as it is consistent with its overall
compensation objective, to structure executive compensation to minimize
application of the deduction limitations of Section 162(m) of the Code.

Compensation Committee:

                                          James P. Schadt, Chairman
                                          Dennis G. Sisco
                                          Mark C. Stevens

                         STOCK OPTION COMMITTEE REPORT

     In 2002, stock options were granted in accordance with Mercator'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 Mercator,
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 Mercator 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 Mercator 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 Mercator
Common Stock on the date of grant.

     In January 2002, the Stock Option Committee granted Mr. King, Mercator's
Chairman of the Board of Directors, Chief Executive Officer and President,
300,000 options. The Stock Option Committee's determina-

                                        15


tion to grant such stock options was based on Mercator performance in 2001 (and
that such performance was the result of his contributions) and the significant
increase in market valuation realized by Mercator 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.

     Mercator also granted other executives stock options in January 2002 based
on Mercator performance in 2001 and the significant increase in market valuation
realized by Mercator. In December 2002, in light of disappointing third quarter
results and a recently completed workforce reduction which resulted in a 31%
reduction in Mercator headcount, a proposal was made to accelerate the date for
the granting of stock options from January 2003 to December 2002. 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 are
important to the success of Mercator 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 Mercator's
decision to freeze all executive and management salaries at the 2002 level, and
the recently-undertaken workforce reduction. The Board approved the proposed
option grants stipulating no further grants can be made to existing employees
for 2003 or 2004 unless specifically approved by them in connection with a
promotion or other extraordinary circumstances.

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

                                          Dennis G. Sisco

OPTION GRANTS IN 2002

     The following table sets forth information regarding option grants during
2002 pursuant to Mercator'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
Mercator's estimate or projection of future Mercator Common Stock price or value
of Mercator.

(1) The options shown in the table were granted at fair market value, are
    incentive stock options (to the extent permitted under the Code) and will
    expire ten years from the date of grant, subject to earlier termination upon
    termination of the optionee's employment.

(2) Potential realizable values are calculated based on the fair market value of
    Mercator Common Stock at the date of grant minus the exercise price.

(3) These options vest 50% on each of 1/2/2005 and 1/2/2006.

(4) These options vest 25% on the date of grant and the remaining 75% quarterly
    thereafter for four years.

TREATMENT OF OPTIONS

     The Merger Agreement provides that, at the effective time of the Merger,
each then outstanding option to acquire Mercator Common Stock under one of
Mercator's stock option plans (other than under the Directors Plan), whether or
not then exercisable, will (without any action on the part of Mercator):

     - automatically be converted into an option to purchase Ascential's common
       stock;

     - have the same terms, and be subject to the same conditions, as they had
       before Mercator signed the Merger Agreement (after giving effect to any
       acceleration of vesting to which the holders are entitled as a result of
       the transactions contemplated by the Merger Agreement), except that each
       such option will be exercisable for the number of shares of Ascential's
       common stock that is equal to the product of:

        -- the number of shares of Mercator Common Stock issuable upon exercise
           of such option immediately prior to the Merger; and

        -- $3.00 per share divided by the average of: (i) the closing prices of
           Ascential's common stock during the 20 trading days preceding the
           fifth trading day prior to the public announcement of the Merger
           Agreement; and (ii) the closing prices of Ascential's common stock
           during the 20 trading days preceding the fifth trading day prior to
           the date of the Merger (such average, the "Option Exchange Ratio");

                                        17


     - the per share exercise price of each such option will be changed to the
       quotient equal to: (i) the exercise price of such option immediately
       prior to the effective time of the Merger; and (ii) the Option Exchange
       Ratio.

     Mercator's Directors Plan provides that, prior to the effective time of the
Merger, all of the then outstanding options thereunder will become fully vested
and exercisable and that, following the effective time of the Merger, any
unexercised options thereunder will be cancelled.

     The number of shares of Mercator Common Stock subject to options granted to
(a) directors, the vesting of which would be accelerated in the manner described
above, is as follows: Ms. Galley, 77,500 shares; Mr. Keet, 40,000 shares; Mr.
King, 621,876 shares; Mr. Lehman, 85,500 shares; Mr. Schadt, 43,000 shares; Mr.
Sisco, 40,000 shares; and Mr. Stevens, 54,250 shares and (b) non-director
executive officers, the vesting of which would be accelerated in the manner
described above and under "Change of Control Arrangements," is as follows: Mr.
Collins, 89,064 shares; Ms. Donohoe, 227,351 shares; Mr. Goret, 90,470 shares;
Mr. Hall, 348,874 shares; Mr. Klein, 31,462 shares; Mr. Linthicum, 342,197
shares; Mr. Register, 302,815 shares; Mr. Smith, 104,376 shares; and Mr.
Varvoglis, 104,301 shares.

however, he will receive such payments and benefits for a three year period.
Also, upon a change of control, Mr. King is eligible to receive certain
additional benefits. See "Change of Control Arrangements," below.

bonus at 100% of his then base salary and twelve months of continued eligible
benefits and other executive perquisites. Mr. Hall is entitled to receive term
life insurance valued at $1,000,000 paid by Mercator. Upon a change of control,

of Mercator Common Stock. Ms. Donohoe received a sign-on bonus of $100,000. Ms.
Donohoe is eligible for a target bonus of 100% of her base salary, with a payout
range of 0% to 300% of her base salary based upon meeting certain corporate and
business unit performance goals. If Ms. Donohoe is terminated for any reason
other than for cause, her agreement provides for severance of salary, executive
benefits for medical insurance and other executive perquisites for twelve
months. Ms. Donohoe is entitled to receive term life insurance valued at
$500,000 paid by Mercator. Upon a change of control, Ms. Donohoe is eligible to

eligible for a target bonus of 100% of base salary with a payout range of 0% to

Mr. Register was on an assignment in Germany and as such received paid benefits
including housing, education for family members, relocation expenses and certain
tax equalization payments. Mr. Register is now on a two-year assignment in the
United States as of August 1, 2002. If Mr. Register is terminated for any reason

Arrangements," below.

     Mr. Wheeler's agreement provides for an annual base salary of $250,000 and
an option grant to purchase an aggregate of 300,000 shares of Mercator Common
Stock. In 2001, Mr. Wheeler received a sign-on bonus of $100,000. Mr. Wheeler
left Mercator on November 8, 2002 with an annual salary of $265,000. Mr. Wheeler
is receiving severance payments equal to his annual salary and continued
medical, dental and MERP benefits under COBRA for a period of twelve months from
his termination date.

     Mr. Farrell's agreement provides for an annual base salary of $225,000 and
an option grant to purchase an aggregate of 200,000 shares of Mercator Common
Stock. Mr. Farrell left Mercator on August 21, 2002. Mr. Farrell's vested option
expiration date was extended until February 28, 2003. Mr. Farrell received two
month's base salary at termination.

     New Employment Arrangements.  Mark W. Register, Mercator's Executive Vice
President and President, Worldwide Field Operations, and Thracy P. Varvoglis,
Mercator's Senior Vice President, Financial Services and Industry Solutions
Group, will, upon consummation of the Offer, become employees of Ascential. Mr.
Register will receive base salary of $250,000 per year and have a bonus
opportunity equal to 50% of his base salary pursuant to Ascential's Key Employee
Incentive Plan. Mr. Varvoglis will receive base salary of $200,000 per year and
have a bonus opportunity equal to 50% of his base salary pursuant to Ascential's
Key Employee Incentive Plan. Messrs. Register and Varvoglis will also enter into
change in control agreements with Ascential upon the effectiveness of their
employment agreements that will, upon a change in control of Ascential, provide
each of them with 100% vesting of their then unvested stock options and,
following a termination without "cause" or with "good reason" within one year
following the change in control, provide Mr. Register with severance equal to
two times his then annual base salary and target bonus and Mr. Varvoglis with
severance equal to one times his then annual base salary and target bonus.

     Messrs. Register and Varvoglis have waived the right to receive certain
benefits pursuant to Mercator's change of control protection plan discussed
below and have entered into retention agreements with Ascential to become
effective upon consummation of the Offer. Under these retention agreements,
Ascential has agreed to pay them retention amounts as follows: (a) 15% of such
amount on the six-month anniversary of consummation of the Offer; (b) 25% of
such amount on the one-year anniversary of consummation of the
                                        19


Offer; (c) 30% of such amount on the 18-month anniversary of consummation of the
Offer; and (d) the remainder of such amount on the two-year anniversary of
consummation of the Offer. Other than with respect to a termination by Ascential
that is not for "cause" or a departure by the executive for "good reason," they
will lose the right to receive any amount they have not been paid if their
employment with Ascential terminates. (The amounts to which Messrs. Register and
Varvoglis are so entitled are equal to the amounts they would have received
under Mercator's change of control protection plan if they had been
constructively terminated and are described below under "Change of Control
Arrangements.") If, during the first year of their employment with Ascential,
either of Messrs. Register or Varvoglis is terminated by Ascential other than
for "cause" or if they leave for "good reason," they will be entitled to receive
the greater of the amount due to them as described above and, if applicable, the
amount due to them under their change of control agreements with Ascential.
Messrs. Register and Varvoglis have also entered into non-disclosure,
non-competition, non-solicitation and development agreements with Ascential
pursuant to which they have agreed, among other things, not to compete with
Ascential during the term of their employment and for one year thereafter.

     Roy C. King, Mercator's Chairman of the Board of Directors, Chief Executive
Officer and President, Michael J. Collins, Mercator's Senior Vice President and
Chief Marketing Officer, Jill M. Donohoe, Mercator's Senior Vice President,
Global Alliances and Corporate Development, David L. Goret, Mercator's Senior
Vice President, General Counsel and Secretary, Kenneth J. Hall, Mercator's
Executive Vice President, Chief Financial Officer and Treasurer, David S.
Linthicum, Mercator's Executive Vice President, Software Development and Chief
Technology Officer, and Ronald R. Smith, Mercator's Senior Vice President and
Chief Administrative Officer, have entered into continuity agreements with
Mercator. These continuity agreements will, if they remain employed by Mercator,
provide them with the same salary and benefits they presently receive from
Mercator for 60 days following consummation of the Offer. Additionally, they
will lose certain of the severance benefits to which they are otherwise entitled
from Mercator following a change of control if they are fired for "cause" during
such 60-day period. Each person who signed a continuity agreement will,
following their departure from Mercator (and upon signing a release in favor of
Ascential), receive the severance benefits to which they are presently entitled
paid out over one year (instead of, in some cases, 18 months or longer).

     All of Mercator's executive officers have signed a non-competition,
non-solicitation and development agreement in which they have agreed not to
compete with Ascential or Mercator for one year following the termination of
their employment with Mercator.

     Bonus Pool.  The Board has reserved a bonus pool of $400,000, to be awarded
to employees of Mercator that are identified by the Board or its Compensation
Committee.

     Change of Control Arrangements.  In December 2001, the Compensation
Committee of the Board adopted a change of control protection plan. Pursuant to
this plan, upon consummation of the Offer (but without giving effect to the new
employment arrangements described above): (a) Messrs. King, Hall and Linthicum
will receive: (i) full acceleration of unvested options; and (ii) in the event
of constructive termination, as defined below, within one year of the change in
control, pro-ration of year-to-date annual bonus, eighteen months severance
(salary and target bonus) and continued benefits for eighteen months (pursuant
to his employment agreement, Mr. King will receive three years severance (salary
and target bonus) and benefits); (b) Messrs. Collins, Goret, Register, Smith and
Varvoglis and Ms. Donohoe will receive: (i) 50% acceleration of unvested stock
options; and (ii) if constructively terminated within one year of the change of
control, full acceleration of unvested stock options, pro-ration of year to date
annual bonus, 12 months severance (salary and target bonus) and benefits; and
(c) Gerald E. Klein, Mercator's General Counsel, Americas and Assistant
Secretary, will receive: (i) one year acceleration of unvested stock options,
and (ii) if constructively terminated within six months, full acceleration of
unvested stock options.

     Constructive termination is defined as the occurrence of any of the
following, without the employee's written consent: (a) a significant diminution
of, or the assignment to the employee of any duties inconsistent with the
employee's title, status, duties or responsibilities; (b) a reduction in annual
base salary, target bonus or fringe benefit which by itself or in the aggregate
is material to employee's compensation; (c) the relocation of employee's office
more than fifty miles from the employee's current location; or (d) the failure
to obtain the

                                        20


written assumption of employee's employment agreement by any successor to all or
substantially all of Mercator's assets or business within thirty days after a
merger, consolidation, sale or a change of control.

     As a result of the foregoing change of control plan, the approximate
amounts payable to each executive officer (not including the amount attributable
to the continuation of benefits under the change of control plan) would be as
follows (assuming that the vesting of their options is fully accelerated): Mr.
King, $3.5 million ($0.8 million of which is attributable to the assumed
cash-out of stock options at the price offered by Purchaser pursuant to the
Offer); Mr. Hall $1.9 million ($0.8 million of which is attributable to the
assumed cash-out of stock options at the price offered by Purchaser pursuant to
the Offer); Mr. Linthicum, $1.6 million ($0.6 million of which is attributable
to the assumed cash-out of stock options at the price offered by Purchaser
pursuant to the Offer), Mr. Collins, $0.9 million ($0.3 million of which is
attributable to the assumed cash-out of stock options at the price offered by
Purchaser pursuant to the Offer); Ms. Donohoe, $1.1 million ($0.5 million of
which is attributable to the assumed cash-out of stock options at the price
offered by Purchaser pursuant to the Offer); Mr. Goret, $0.8 million ($0.3
million of which is attributable to the assumed cash-out of stock options at the
price offered by Purchaser pursuant to the Offer); Mr. Klein, $0.1 million (all
of which is attributable to the assumed cash-out of stock options at the price
offered by Purchaser pursuant to the Offer); Mr. Register, $1.4 million ($0.7
million of which is attributable to the assumed cash-out of stock options at the
price offered by Purchaser pursuant to the Offer); Mr. Smith, $0.8 million ($0.2
million of which is attributable to the assumed cash-out of stock options at the
price offered by Purchaser pursuant to the Offer); and Mr. Varvoglis, $0.9
million ($0.2 million of which is attributable to the assumed cash-out of stock
options at the price offered by Purchaser pursuant to the Offer).

            SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

     Section 16(a) of the Exchange Act, requires the Mercator's officers and
directors, and persons who own more than 10 percent of a registered class of the
Mercator's equity securities, to file reports of their ownership with the SEC.
Officers, directors and greater than ten percent shareholders are required by
SEC regulation to furnish Mercator with copies of all Section 16(a) reports they
file. Specific due dates for these reports have been established and Mercator is
required to report in this information statement any delinquent filings and
failures to file such reports.

     Based solely on its review of the copies of such reports received by it and
written representations of its incumbent directors and officers, to Mercator's
knowledge, during the period from January 1, 2002 to December 31, 2003 all such
filings were made on a timely basis, except that the November 27, 2002 Form 4
for David S. Linthicum, which was due on December 2, 2002, was filed on December
6, 2002; the December 18, 2002 Form 4's for Constance F. Galley, Ernest E. Keet,
James P. Schadt, Michael E. Lehman, Dennis G. Sisco, Mark C. Stevens, Roy C.
King, David L. Goret, Gerald E. Klein, Gregory G. O'Brien, Kenneth J. Hall, Jill
M. Donohoe, Michael J. Collins, Mark W. Register, Ronald R. Smith and Thracy P.
Varvoglis, which were due on December 20, 2002, were filed on December 23, 2002;
and the Form 4 for Ernest E. Keet filed on December 23, 2002 was amended on
April 8, 2003 to reflect a different allocation of reported securities among
controlled entities.

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

     In December 2000, Mercator entered into a license agreement with Harvard
Pilgrim Health Care ("Harvard Pilgrim"). The chief executive officer of Harvard
Pilgrim is Mr. Schadt's son-in-law. Under the license agreement, Harvard Pilgrim
purchased for $495,000 the right to use Mercator's electronic data interchange,
or EDI, software and certain health care transaction processing software.
Harvard Pilgrim also paid Mercator a maintenance fee of $84,150 in 2001 and
2002), and will pay a maintenance fee of $87,516 for 2003. The purchase price
for the license and the annual maintenance fees are comparable to the amounts
charged to Mercator's other customers for such products and services.

     For additional relationships and related transactions, see "Compensation of
Directors" on page 7 and "New Employment Arrangements" on page 19.

incorporating by reference this Information 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 Mercator 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
Mercator's Common Stock from August 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 Mercator Common Stock and in
each of the other indices on August 3, 1997, and reinvestment of all dividends,
if any). Mercator 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.
