        E-Sync Networks Signs Letter Of Intent For Merger With SpaceLogix
- --------------------------------------------------------------------------------

TRUMBULL, CT, MAY 7, 2001 - E-Sync Networks, Inc. (NASDAQ: ESNI;
www.esyncnetworks.com), a leading provider of e-business infrastructure products
and services, has signed a non-binding letter of intent to merge with
SpaceLogix, Inc., a privately-held company formed to exploit the market
opportunity for co-location and network managed services in third party data
centers.

According to the terms of the letter of intent, E-Sync and SpaceLogix will
immediately commence negotiating a definitive merger agreement. As one of the
conditions for execution of the definitive merger agreement, SpaceLogix will
provide one or more bridge loans to E-Sync of at least $1,050,000, which would
be converted into common stock upon consummation of the merger. Additionally,
SpaceLogix would agree in the definitive merger agreement to cause its
investment banker, Trautman Wasserman & Company, Inc to undertake an additional
best efforts equity capital raise of $2,000,000 to $3,500,000 for the merged
entity.

Upon the consummation of the merger, (i) SpaceLogix would merge into a
subsidiary of E-Sync, (ii) E- Sync stockholders would retain their currently
outstanding securities in E-Sync, and (iii) SpaceLogix' stockholders would
receive the following consideration:

         -        First, that number of shares of E-Sync common stock equal to
                  the sum of (x) 6,000,000 plus (y) that number of shares equal
                  to the quotient of the amounts bridge loaned by SpaceLogix to
                  E- Sync divided by 80% of the average share price at the time
                  of the loan(s);

         -        Second, 1,200,000 shares of E-Sync's new series C preferred
                  stock, which (x) if, within 120 days of the consummation of
                  the merger, the combined company is able to complete a private
                  placement of a minimum of $2 million of new equity capital
                  (the "Private Placement"), in addition to the amount
                  previously bridge loaned, would convert into an aggregate
                  amount of 12,000,000 shares of E-Sync's common stock, and (y)
                  if the Private Placement is not consummated within 120 days of
                  the merger, would instead be thereafter redeemed for an
                  aggregate cash consideration of $600,000; and

         -        Third, warrants to acquire 5,500,000 shares of E-Sync common
                  stock, with an exercise price equal to 85% of the average
                  closing price of E-Sync's common stock over the five trading
                  days prior to the date the definitive merger agreement is
                  executed, the exercisability of which would be subject to the
                  merged entity meeting the following performance criteria:

                  -        (i) 1,833,000 shall be exercisable at such time as
                           E-Sync has increased monthly gross margin on sales
                           above the level recorded at April 30, 2001 by
                           $100,000 for three consecutive months, (ii) 1,833,000
                           shall be exercisable at such time as E-Sync has net
                           after tax income (but excluding any goodwill
                           amortization charges arising by virtue of the merger)
                           for a period of three consecutive months and (iii)
                           1,834,000 shall be

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

                           exercisable at such time as the balance sheet current
                           ratio will exceed 1:1 for a period of three
                           consecutive months commencing not earlier than
                           November, 2001.

                   -       The offer and sale of E-Sync securities in connection
                           with the proposed merger and capital raising would
                           not be registered and would therefore be made
                           pursuant to an exemption from registration under the
                           Securities Act of 1933, as amended. E-Sync will agree
                           to use its best efforts to file and have declared
                           effective a shelf registration statement covering the
                           resale of (i) all of the securities to be issued upon
                           conversion of the notes issued in connection with the
                           bridge loans, (ii) all of the securities to be issued
                           in connection with the capital raising following
                           consummation of the merger and (iii) 500,000 shares
                           of E-Sync common stock issued to SpaceLogix
                           stockholders as part of the merger consideration.

Upon execution of the definitive merger agreement, SpaceLogix would be entitled
to name up to two members of E-Sync's board of directors, currently fixed at a
total of seven members; upon successful completion of the Private Placement,
SpaceLogix would be entitled to name an additional two members of E-Sync's
board, thus giving it control thereof. The merged entity will continue under the
"E-Sync Networks, Inc." name.

In connection with the letter of intent, E-Sync announced that it had entered
into agreements with SpaceLogix and Trautman Wasserman for the provision of
certain management consulting services. While the letter of intent is
non-binding, the aforesaid consulting agreements would require E-Sync to pay
SpaceLogix and Trautman Wasserman an aggregate of $150,000 in the event that the
merger does not occur, except to the extent that SpaceLogix or Trautman
Wasserman causes the merger not to occur. In addition, if the merger does not
occur and E-Sync borrows money from SpaceLogix pursuant to the aforesaid bridge
loan, then the bridge note would have to be repaid, with interest, plus an extra
25% or 35% of principal, depending upon whether the repayment is within 270 days
of today or later.

"We believe this merger can help us accelerate the achievement of our business
objectives," said Michael A. Clark, President and COO of E-Sync. "SpaceLogix
brings not only a compatible vision of the market opportunity for networked
managed services, but also a seasoned management team."

According to Douglas C. Greenwood, acting Chairman of SpaceLogix and Managing
Director of Trautman Wasserman, "The timing on this could not have been better.
We have been aggressively studying the co-location and managed services space
over the past year, developed a compelling business strategy and service
offerings and assembled our senior management team. We believe that the merger
with E-Sync will save us both significant time and money entering this exciting
marketplace."
