                                  SCHEDULE 13D

     The following constitutes Amendment No. 4 to the Schedule 13D filed by the
undersigned on November 29, 2002, as amended on February 4, 2003, March 14, 2003
and March 31, 2003, and amends such Schedule 13D only to the extent set forth
herein.

ITEM 1. SECURITY AND ISSUER

     This Amendment No. 4 to Schedule 13D relates to the Common Stock, par value
$0.01 per share (the "Common Stock") of Mercator Software, Inc., a Delaware
corporation (the "Issuer"), having its principal executive offices at 45 Danbury
Road, Wilton, Connecticut 06897.

ITEM 2. IDENTITY AND BACKGROUND

     This Amendment No. 4 to Schedule 13D is filed by Broken Arrow I, L.P., a
Delaware limited partnership ("Broken Arrow"); Strategic Software Holdings, LLC,
a Connecticut limited liability company ("SSH"); Bienvenu Management, LLC, a
Connecticut limited liability company ("Bienvenu Management"), Rodney Bienvenu,
James Dennedy, Empire Capital Partners, L.P., a Delaware limited partnership
("Empire Capital"); Empire GP, L.L.C., a Delaware limited liability company
("Empire GP"); Empire Capital Management, L.L.C., a Delaware limited liability
company ("Empire Capital Management") Charter Oak Partners, L.P., a Connecticut
limited partnership ("Charter Oak"), Scott A. Fine, Peter J. Richards, Peter J.
Boni, Daniel Hoogterp, Edward Sanchez, Jr., Sean P. Sears and Michael R.
Wodopian (all of such persons, collectively, the "Reporting Persons").

ITEM 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION

     The shares of Common Stock originally purchased by Broken Arrow were
purchased with working capital of Broken Arrow received as proceeds from a loan
to Broken Arrow by Empire Capital. Empire Capital loaned Broken Arrow $2,000,000
on November 14, 2000, which loan is evidenced by a Secured Demand Note in the
stated principal amount of $2,300,000 with no stated interest. The Secured
Demand Note is secured by a first priority lien on all of the property of Broken
Arrow, including any property of Broken Arrow acquired after the date thereof,
which would include the Common Stock of the Issuer held by Broken Arrow. The
Secured Demand Note is payable upon demand after 90 days notice. A copy of the
Secured Demand Note is attached hereto as Exhibit 7.10.

ITEM 4. PURPOSE OF TRANSACTION

     On April 1, 2003, SSH held a meeting with the Issuer to discuss the terms
of a proposal to acquire the Issuer contained in a letter from SSH to the Issuer
dated March 31, 2003. SSH had hoped to have a meaningful, collaborative
discussion on all elements of its proposal and to discuss the basis on which the
parties could come to a friendly agreement. The Issuer refused to discuss such
terms or to discuss the basis on which the parties could come to a friendly
agreement. A copy of SSH's press release with regard to the meeting was filed
with the Securities and Exchange Commission on April 1, 2003.


                                       18


ITEM 5. INTEREST IN SECURITIES OF THE ISSUER

     (a) and (b)

     Empire Capital does not directly own any shares of Common Stock but because
it holds a 25% interest in SSH, it may be deemed to be a beneficial owner of the
1,672,500 shares of Common Stock representing 4.76% of the outstanding shares of
Common Stock held by Broken Arrow. In addition, all investment decisions with
regard to Broken Arrow are subject to the determinations of the Investment
Committee, which is comprised of a representative of SSH and a representative of
Empire Capital.

     (c)  None of the Reporting Persons has purchased or sold any of the
Issuer's Common Stock since the date of the their most recent filing on Schedule
13D.

ITEM 6. CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT TO
SECURITIES OF THE ISSUER

     Empire Capital loaned Broken Arrow $2,000,000 on November 14, 2000, which
loan is evidenced by a Secured Demand Note in the stated principal amount of
$2,300,000 with no stated interest. The Secured Demand Note is secured by a
first priority lien on all of the property of Broken Arrow, including any
property of Broken Arrow acquired after the date thereof, which would include
the Common Stock of the Issuer held by Broken Arrow. The Secured Demand Note is
payable upon demand after 90 days notice. A copy of the Secured Demand Note is
attached hereto as Exhibit 7.10.

ITEM 7. MATERIAL TO BE FILED AS EXHIBITS
