13.2     Without limiting the foregoing, either party shall have the further
right to terminate this agreement upon notice that the other party has
committed a material breach of its obligations under this agreement and has
failed to cure such breach within 15 days of notice of such breach. NEIC shall
have the further right to terminate this agreement or any specific NEIC
Services effective immediately upon the occurrence of any of the following
events:

         a.       Upon notice by NEIC to Vendor that NEIC is no longer offering
or providing support for the applicable Service; or

         b.       In the event Vendor fails to conform with any non-optional
portion of the Transaction Specifications then in effect or utilizes any aspect
of the NEIC Services on equipment or with software which is not then authorized
for such use by NEIC.

13.3     Failure by Vendor to fully satisfy any of its obligations with respect
to any specific NEIC Service shall give NEIC the right to terminate the use by
Vendor of such Service and to maintain the rest of this agreement in full force
and effect with respect to the other NEIC Services. This provision, however,
does not limit NEIC's right to treat such failure as the basis for termination
of this agreement in whole or to exercise any other right or remedy which NEIC
may have as a result of such failure.

13.4     Upon termination of this agreement or any specific NEIC Services for
any reason, Vendor shall promptly cease all use of the affected Service and, at
Vendor's expense, cause to be returned to NEIC all NEIC Materials (including
any and all documentation) provided by NEIC (and all copies thereof) with
respect to the terminated Service.

14.      General

14.1     Each party shall comply with any applicable law or industry practice
and shall secure any authorization required by applicable law, industry
practice or otherwise in connection with the aspect of the transaction
submission process for which it is responsible under this agreement.

14.2     Supplementing Sections B.6.3 and B.7.1, each party shall retain in
confidence the terms of this agreement and any and all confidential or
proprietary information regarding the other party or the NEIC Services
transmitted by the other party which is marked "Confidential" (all of which are
hereinafter called "Information"). Each party shall make no use of information
except as required to perform in accordance with the terms of this agreement.
Information shall be protected by each party in a manner which shall be no less
protective than the manner such party then uses to protect its own confidential
information, and such information shall not be disclosed to any person other
than one for whom such knowledge is essential for the purposes of this
agreement, and then only to the degree such disclosure is so essential and only
if the recipient expressly agrees to be bound by provisions of confidentiality
which are no less than the confidentiality provisions of this Section B.14.2.
This provision shall survive the termination or expiration of this agreement.

14.3     Vendor shall make its operations, methods, documentation and
appropriate personnel accessible to NEIC as NEIC may reasonably require to
enable NEIC to confirm Vendor's compliance with Vendor's obligations pursuant
to this agreement in accordance with the standards and quality contemplated by
this agreement.

14.4     At any time, NEIC may request by notice the right to have access to
healthcare administrators (other than NEIC Payors) connected to Vendor for
which Vendor is compensated for all transactions submitted through the NEIC
Services (including the On Line Services) on terms and conditions to NEIC which
shall be no less favorable than the terms and conditions which NEIC then
affords to Vendor for transactions submitted to the NEIC Services. If within 60
days of such NEIC request, an agreement for such access is not executed by
Vendor and NEIC, NEIC shall have the right on 60 days prior notice to terminate
this agreement.

14.5     The parties will act as independent contractors, and this agreement
does not constitute either party as the agent or partner of the other party.

14.6     Notices required hereunder will be in writing signed by an officer of
the notifying party and delivered personally or by overnight courier service or
sent by registered or certified mail, charges prepaid, to the address noted at
the top of this agreement (or to such other address as the recipient may have
previously designated by notice), and will be deemed given when so delivered or
four days after the date of mailing, whichever occurs first.

14.7     This agreement and the rights and obligations hereunder may not be
assigned or sublicensed by either party, in whole or in part, without the prior
written consent of the other party, which consent shall not be unreasonably
withheld.

14.8     No representations have been made to induce either party to enter into
this agreement except for the representations explicitly stated in this
agreement. This agreement supersedes all prior or contemporaneous agreements or
expressions of intent or understanding and is the entire agreement between the
parties with respect to its subject matter.

14.9     All terms, conditions or provisions which may appear on any purchase
or sales order or invoice issued pursuant to this agreement shall, to the
extent inconsistent with the terms and conditions of this agreement, be of no
force or effect, notwithstanding the fact that such order or invoice may have
been executed subsequent to the date of this agreement and, in any event,
preprinted terms of any such order or invoice shall have no force or effect.

14.10    In the event of a breach of any provision of this agreement by either
party, the other party, in addition to any other remedy it may have, shall be
entitled to recover reasonable attorneys fees and expenses incurred as a result
of such breach.

14.11    No provision of this agreement may be waived, except by a writing
signed by an executive officer of the party charged with such waiver and any
such waiver shall be limited to the terms of such writing.

14.12    This agreement may not be changed or terminated (other than as
expressly set forth in this agreement) except by a writing signed by an
authorized officer of NEIC and by an authorized officer of Vendor.

14.13    This agreement is governed as to interpretation and enforcement by the
laws of the State of New Jersey and the parties hereby consent to the
jurisdiction of such State as the exclusive forum for litigating any dispute
arising out of this agreement or out of its subject matter.

By signing below, the parties agree to all of the terms and conditions set
forth above.

NEIC on a monthly basis. Accompanying each such invoice shall be a report
identifying the number of claims on which such invoice is based.

     The Agreement is hereby amended to enable Vendor to use the NEIC ERA

which were not delivered through the NEIC Services ("Non-NEIC Claims"), (ii)
claims which were delivered electronically by the NEIC Services to an entity

Vendor from time to time) which are entities who do not pay NEIC to receive
such claims ("Non-Participating Payor Claims") and (iii) claims which were
delivered electronically by the NEIC Services to an entity not identified as a
Non-Participating Payor ("Participating Payor Claims").

     2.   Vendor shall pay NEIC 10 cents for each Participating Payor Claim, 20

NEIC on a monthly basis. Accompanying each such invoice shall be a report
identifying the number of claims on which such invoice is based.

     4.   Notwithstanding the foregoing, in the event that the total charges
imposed on Vendor hereunder for Vendor's use of the NEIC ERA Services in any
month following the first three full calendar months of Vendor's use of such
Services is less than $50, in lieu of such charges, NEIC shall invoice Vendor
and Vendor shall pay $50 for its use of such Services in such month.

     5.   The definitions of terms appearing in the Agreement shall apply to
