           CONFIDENTIAL INFORMATION AND OWNERSHIP INVENTION ASSIGNMENT
                            AGREEMENT FOR CONSULTANT


         This CONFIDENTIAL INFORMATION AND INVENTION ASSIGNMENT AGREEMENT (the
"Agreement") is made between E-Sync Networks, Inc., a Delaware corporation (the
"Company"), and the undersigned consultant (the "Consultant").

         In consideration of my Consultant's relationship with the Company
(which for purposes of this Agreement shall be deemed to include any
subsidiaries or Affiliates of the Company), the receipt of confidential
information while associated with the Company, and other good and valuable
consideration, the undersigned Consultant agrees that:

         1. Term of Agreement. This Agreement shall continue in full force and
effect for the duration of Consultant's relationship with the Company and shall
continue thereafter until terminated through a written instrument signed by both
parties hereto.

         2.       Confidentiality.

                  (a)      Definitions.

                  "Proprietary Information" is all information and any idea
whatever form, tangible or intangible, pertaining in any manner to the business
of the Company, or any of its Affiliates, or its employees which was produced by
any employee or consultant of the Company in the course of his or her employment
or consulting relationship or otherwise produced or acquired by or on behalf of
the Company. All Proprietary Information not generally known outside of the
Company's organization, and all Proprietary Information so known only through
improper means, shall be deemed "Confidential Information." By example and
without limiting the foregoing definition, Proprietary and Confidential
Information shall include, but not be limited to:

                           (1) formulas, research and development techniques,
         processes, trade secrets, computer programs, software, electronic
         codes, mask works, inventions, innovations, patents, patent
         applications, discoveries, improvements, data, know-how, formats, test
         results, and research projects;

                           (2) information about costs, profits, markets, sales,
         contracts and lists of customers, and distributors;

                           (3) business, marketing, and strategic plans;

                           (4) forecasts, unpublished financial information,
         budgets, projections, and customer identities, characteristics and
         agreements; and
<PAGE>   8
                           (5) employee personnel files and compensation
         information.

         Confidential Information is intended to be broadly defined, and
includes all information that has or could have commercial value or other
utility in the business in which the Company is engaged or contemplates
engaging, and all information of which the unauthorized disclosure could be
detrimental to the interests of the Company, whether or not such information is
identified as Confidential Information by the Company.

                  (b) Existence of Confidential Information. The Company owns
and has developed and compiled, and will develop and compile, certain trade
secrets, proprietary techniques and other Confidential Information which have
great value to its business. This Confidential Information includes not only
information disclosed by the Company to Consultant, but also information
developed or learned by Consultant during the course of Consultant's
relationship with the Company.

                  (c) Protection of Confidential Information. Consultant will
not, directly or indirectly, use, make available, sell, disclose or otherwise
communicate to any third party, other than in Consultant's assigned duties and
for the benefit of the Company, any of the Company's Confidential Information,
either during or after Consultant's relationship with the Company. In the event
Consultant desires to publish the results of Consultant's work for the Company
through literature or speeches, Consultant will submit such literature or
speeches to the President or Chief Operating Officer of the Company at least 10
days before dissemination of such information for a determination of whether
such disclosure may alter trade secret status, may be prejudicial to the
interests of the Company, or may constitute an invasion of its privacy.
Consultant agrees not to publish, disclose or otherwise disseminate such
information without prior written approval of the President or Chief Operating
Officer of the Company. Consultant acknowledges that it is aware that the
unauthorized disclosure of Confidential Information of the Company may be highly
prejudicial to its interests, an invasion of privacy, and an improper disclosure
of trade secrets.

                  (d) Delivery of Confidential Information. Upon request or when
Consultant's relationship with the Company terminates, Consultant will
immediately deliver to the Company all copies of any and all materials and
writings received from, created for, or belonging to the Company including, but
not limited to, those which relate to or contain Confidential Information.

                  (e) Location and Reproduction. Consultant shall maintain at
Consultant's workplace only such Confidential Information as Consultant has a
current "need to know." Consultant shall return to the appropriate person or
location or otherwise properly dispose of Confidential Information once that
need to know no longer exists. Consultant shall not make copies of or otherwise
reproduce Confidential Information unless there is a legitimate business need of
the Company for reproduction.

                  (f) Prior Actions and Knowledge. Consultant represents and
warrants that from the time of Consultant's first contact with the Company,
Consultant held in strict confidence all Confidential Information and has not
disclosed any Confidential Information, directly or indirectly, to anyone
outside the Company, or used, copied, published, or summarized any Confidential
Information, except to the extent otherwise permitted in this Agreement.

                  (g) Third-Party Information. Consultant acknowledges that the
Company has received and in the future will receive from third parties their
confidential information subject to a duty on the Company's part to maintain the
confidentiality of such information and to use it only for certain limited

                                       -2-
<PAGE>   9
purposes. Consultant agrees that it will at all times hold all such confidential
information in the strictest confidence and not to disclose or use it, except as
necessary to perform Consultant's obligations hereunder and as is consistent
with the Company's agreement with such third parties.

                  (h) Third Parties. Consultant represents that its relationship
with the Company does not and will not breach any agreements with or duties to
any other third party. Consultant will not disclose to the Company or use on its
behalf any confidential information belonging to others and Consultant will not
bring onto the premises of the Company any confidential information belonging to
any such party unless consented to in writing by such party.

         3.       Proprietary Rights, Inventions and New Ideas.

                  (a) Definition. The term "Subject Ideas or Inventions"
includes any and all ideas, processes, trademarks, service marks, inventions,
designs, technologies, computer hardware or software, original works of
authorship, formulas, discoveries, patents, copyrights, copyrightable works
products, marketing and business ideas, and all improvements, know-how, data,
rights, and claims related to the foregoing that, whether or not patentable,
which are conceived, developed or created which: (1) relate to the Company's
current or contemplated business; (2) relate to the Company's actual or
demonstrably anticipated research or development; (3) result from any work
performed by Consultant for the Company; (4) involve the use of the Company's
equipment, supplies, facilities or trade secrets; (5) result from or are
suggested by any work done by the Company or at the Company's request, or any
projects specifically assigned to Consultant; or (6) result from Consultant's
access to any of the Company's memoranda, notes, records, drawings, sketches,
models, maps, customer lists, research results, data, formulae, specifications,
inventions, processes, equipment or other materials (collectively, "Company
Materials").

                  (b) Company Ownership. All right, title and interest in and to
all Subject Ideas and Inventions, including but not limited to all registrable
and patent rights which may subsist therein, shall be held and owned solely by
the Company, and where applicable, all Subject Ideas and Inventions shall be
considered works made for hire. Consultant shall mark all Subject Ideas and
Inventions with the Company's copyright or other proprietary notice as directed
by the Company and shall take all actions deemed necessary by the Company to
protect the Company's rights therein. In the event that the Subject Ideas and
Inventions shall be deemed not to constitute works made for hire, or in the
event that Consultant should otherwise, by operation of law, be deemed to retain
any rights (whether moral rights or otherwise) to any Subject Ideas and
Inventions, Consultant agrees to assign to the Company, without further
consideration, Consultant's entire right, title and interest in and to each and
every such Subject Idea and Invention.

                  (c) Disclosure. Consultant agrees to disclose promptly to the
Company full details of any and all Subject Ideas and Inventions.

                  (d) Maintenance of Records. Consultant agrees to keep and
maintain adequate and current written records of all Subject Ideas and
Inventions and their development made by Consultant (solely or jointly with
others) during the term of Consultant's relationship with the Company. These
records will be in the form of notes, sketches, drawings, and any other format
that may be specified by the Company. These records will be available to and
remain the sole property of the Company at all times.

                  (e) Determination of Subject Ideas and Inventions. Consultant
further agrees that all information and records pertaining to any idea, process,
trademark, service mark, invention, technology, computer hardware or software,
original work of authorship, design, formula, discovery, patent, copyright,
product, and all improvements, know-how, rights, and claims related to the
foregoing ("Intellectual

                                      -3-
<PAGE>   10
Property"), that Consultant does not believe to be a Subject Idea
or Invention, but that is conceived, developed, or reduced to practice by the
Company (alone by Consultant or with others) during Consultant's relationship
with the Company and for one (1) year thereafter, shall be disclosed promptly by
Consultant to the Company. The Company shall examine such information to
determine if in fact the Intellectual Property is a Subject Idea or Invention
subject to this Agreement.

                  (f) Access. Because of the difficulty of establishing when any
Subject Ideas or Inventions are first conceived by Consultant, or whether it
results from my Consultant's access to Confidential Information or Company
Materials, Consultant agrees that any Subject Idea and Invention shall, among
other circumstances, be deemed to have resulted from my Consultant's access to
Company Materials if: (1) it grew out of or resulted from Consultant's work with
the Company or is related to the business of the Company, and (2) it is made,
used, sold, exploited or reduced to practice, or an application for patent,
trademark, copyright or other proprietary protection is filed thereon, by
Consultant or with Consultant's significant aid, during the relationship with
the Company and within one year after termination of Consultant's relationship
with the Company.

                  (g) Assistance. Consultant further agrees to assist the
Company in every proper way (but at the Company's expense) to obtain and from
time to time enforce patents, copyrights or other rights or registrations on
said Subject Ideas and Inventions in any and all countries, and to that end will
execute all documents necessary:

                           (1) to apply for, obtain and vest in the name of the
         Company alone (unless the Company otherwise directs) letters patent,
         copyrights or other analogous protection in any country throughout the
         world and when so obtained or vested to renew and restore the same;

                           (2) to defend any opposition proceedings in respect
         of such applications and any opposition proceedings or petitions or
         applications for revocation of such letters patent, copyright or other
         analogous protection; and

                           (3) to cooperate with the Company (but at the
         Company's expense) in any enforcement or infringement proceeding on
         such letters patent, copyright or other analogous protection.

                  (h) Authorization to Company. In the event the Company is
unable, after reasonable effort, to secure Consultant's signature on any patent,
copyright or other analogous protection relating to a Subject Idea and
Invention, Consultant hereby irrevocably designates and appoints the Company and
its duly authorized officers and agents as its agent and attorney-in-fact, to
act for and on Consultant's behalf and stead to execute and file any such
application, applications or other documents and to do all other lawfully
permitted acts to further the prosecution, issuance, and enforcement of letters
patent, copyright or other analogous rights or protections thereon with the same
legal force and effect as if executed by Consultant. Consultant's obligation to
assist the Company in obtaining and enforcing patents and copyrights for Subject
Ideas and Inventions in any and all countries shall continue beyond the
termination of Consultant's relationship with the Company, but the Company shall
compensate Consultant at a reasonable rate after such termination for time
actually spent by Consultant at the Company's request on such assistance.

                  (i) Acknowledgment. Consultant acknowledges that there are no
currently existing ideas, processes, inventions, discoveries, marketing or
business ideas or improvements which Consultant desires to exclude from the
operation of this Agreement. To the best of Consultant's knowledge, there is no


                                       -4-
<PAGE>   11
other contract to assign inventions, trademarks, copyrights, ideas, processes,
discoveries or other intellectual property that is now in existence between
Consultant and any other person (including any business or governmental entity).

                  (j) No Use of Name. Consultant shall not at any time use the
Company's name or any the Company trademark(s) or trade name(s) in any
advertising or publicity without the prior written consent of the Company.

         4.       Competitive Activity.

                  (a) Acknowledgment. Consultant acknowledges that the pursuit
of the activities forbidden by Section 4(b) below would necessarily involve the
use, disclosure or misappropriation of Confidential Information.

                  (b) Prohibited Activity. To prevent the above-described
disclosure, misappropriation and breach, Consultant agrees that during its
relationship and for a period of one (1) year thereafter, without the Company's
express written consent, Consultant shall not, directly or indirectly, (i)
employ, solicit for employment, or recommend for employment any person employed
by the Company (or any Affiliate); and (ii) engage in any present or
contemplated business activity, other than as currently conducted or
contemplated, that is or may be competitive with the Company (or any Affiliate)
in any state where the Company conducts its business, unless Consultant can

without the use in any way of Confidential Information.

         5.       Representations and Warranties. Consultant represents and
warrants (i) that Consultant has no obligations, legal or otherwise,
inconsistent with the terms of this Agreement or with Consultant's undertaking a
relationship with the Company; (ii) that the performance of the services called
for by this Agreement do not and will not violate any applicable law, rule or
regulation or any proprietary or other right of any third party; (iii) that
Consultant will not use in the performance of Consultant's responsibilities for

                  (d) Consultant hereby grants consent to notification by the
Company to any of Consultant's future employers or companies Consultant consults
with about Consultant's rights and obligations under this Agreement.

                  (e) Upon termination of Consultant's relationship with the
Company, Consultant will execute a Certificate acknowledging compliance with
this Agreement in the form reasonably requested by the Company.

         7. Injunctive Relief. Consultant acknowledges that its failure to carry
out any obligation under this Agreement, or a breach by Consultant of any
provision herein, will constitute immediate and irreparable damage to the
Company, which cannot be fully and adequately compensated in money damages and
which will warrant preliminary and other injunctive relief, an order for
specific performance, and other equitable relief. Consultant further agrees that
no bond or other security shall be required in obtaining such equitable relief
and Consultant hereby consents to the issuance of such injunction and to the
ordering of specific performance. Consultant also understands that other action
may be taken and remedies enforced against Consultant.

         8. Modification. No modification of this Agreement shall be valid
unless made in writing and signed by both parties.

         9. Binding Effect. This Agreement shall be binding upon Consultant's
successors and assign, heirs, executors, assigns and administrators and is for
the benefit of the Company and its successors and assigns.

         10. Governing Law. This Agreement shall be construed in accordance
with, and all actions arising under or in connection therewith shall be governed
by, the internal laws of the State of New York (without reference to conflict of
law principles).

         11. Integration. This Agreement sets forth the parties' mutual rights
and obligations with respect to proprietary information, prohibited competition,
and intellectual property. It is intended to be the final, complete, and
exclusive statement of the terms of the parties' agreements regarding these
subjects. This Agreement supersedes all other prior and contemporaneous
agreements and statements on these subjects, and it may not be contradicted by
evidence of any prior or contemporaneous statements or agreements. To the extent
that the practices, policies, or procedures of the Company, now or in the
future, apply to Consultant and are inconsistent with the terms of this
Agreement, the provisions of this Agreement shall control unless changed in
writing by the Company.

         12. Construction. This Agreement shall be construed as a whole,
according to its fair meaning, and not in favor of or against any party. By way
of example and not limitation, this Agreement shall not be

construed against the party responsible for any language in this Agreement. The
headings of the paragraphs hereof are inserted for convenience only, and do not
constitute part of and shall not be used to interpret this Agreement.

         13. Attorneys' Fees. Should either Consultant or the Company, or any
heir, personal representative, successor or permitted assign of either party,
resort to legal proceedings to enforce this Agreement, the prevailing party (as
defined in New York statutory law) in such legal proceeding shall be awarded, in
addition to such other relief as may be granted, attorneys' fees and costs
incurred in connection with such proceeding.

         14. Severability. If any term, provision, covenant or condition of this
Agreement, or the application thereof to any person, place or circumstance,
shall be held to be invalid, unenforceable or void, the remainder of this
Agreement and such term, provision, covenant or condition as applied to other
persons, places and circumstances shall remain in full force and effect.

         15. Rights Cumulative. The rights and remedies provided by this
Agreement are cumulative, and the exercise of any right or remedy by either the
Company or Consultant (or by that party's successor), whether pursuant hereto,
to any other agreement, or to law, shall not preclude or waive that party's
right to exercise any or all other rights and remedies. This Agreement will
inure to the benefit of the Company and Consultant, and its successors and
assigns.

         16. Nonwaiver. The failure of either the Company or Consultant, whether
purposeful or otherwise, to exercise in any instance any right, power or
privilege under this Agreement or under law shall not constitute a waiver of any
other right, power or privilege, nor of the same right, power or privilege in
any other instance. Any waiver by the Company or by Consultant must be in
writing and signed by a person duly authorized by the Company or Consultant, as
applicable.

         17. Notices. Any notice, request, consent or approval required or
permitted to be given under this Agreement or pursuant to law shall be
sufficient if it is in writing, and if and when it is hand delivered or sent by

office, as the case may be.

necessary to carry out the provisions of this Agreement.

without the Company's prior written consent.

state, and local laws, ordinances and regulations.

employees, consultants, agents and other representatives to comply with the
