                  i.      Corrections. Upon receipt of written notice from
         COMTEX of an error in the distribution of the Service and Content to a
         User, Distributor shall use commercially reasonable efforts to promptly
         correct such error.

                  ii.     Withdrawal of Information Provider. Notwithstanding

         Information Provider, or otherwise violates the proprietary rights of
         an Information Provider, COMTEX, at its sole discretion, immediately
         may cease distribution of such Information Provider's Content to
         Distributor until the violation or infringement is remedied by
         Distributor, during which period Distributor acknowledges that such
         actions by COMTEX shall not result in a breach of Subparagraphs 4.a.
         and 4.b.

         f.       Review by COMTEX

                  i.      Access. Throughout the term of this Agreement,
         Distributor shall provide COMTEX reasonable access to Distributor's
         system for distribution of the Service to Users for the sole purpose of
         reviewing Distributor's implementation of the Service. This access
         shall be provided by Distributor at no charge to COMTEX

                  ii.     Opportunity to Review. Distributor shall provide
         notice to COMTEX to allow COMTEX a reasonable opportunity to review
         Distributor's implementation of the Service before or, if prior review
         is impracticable, as soon as possible after Distributor implements the
         Service or any substantial changes in its implementation of the
         Service.

5.       PAYMENT

         a.       Payment Schedule. Distributor shall pay COMTEX the Monthly

                  (ii)    the Estimated Royalty for the current month, which
         shall be equal to the prior month's actual Royalty; and

                  (iii)   the Royalty Adjustment for the prior month, which
         shall be the amount by which the prior month's Royalty, based on actual
         usage, exceeds the prior month's Estimated Royalty, or Royalty Credit,
         which shall be the amount by which the prior month's Estimated Royalty
         exceeds the prior month's Royalty, based on actual usage. COMTEX shall
         credit Distributor the amount of any Royalty Credit.

Distributor shall pay COMTEX the net amount shown on each invoice within thirty
(30) days of the date of the invoice (the "Due Date").

         c.       Fees Subject to Change. COMTEX may adjust the Fees set forth

right to terminate this Agreement in accordance with Paragraph 6.b.

         g.       Audit. COMTEX or its representative may, during business
hours and upon reasonable notice, inspect and audit the relevant books and
records of Distributor for the sole purpose of verifying all information
related to payments under this Agreement. Such inspection and audit shall be at
the expense of COMTEX unless the audit shows an error of ten percent (10%) or
more in the calculation of Monthly Fees and Royalties, in which case
Distributor shall bear the expense of such inspection and audit. Any deficiency
discovered by the audit shall be paid by Distributor to COMTEX within thirty
(30) days of COMTEX notifying Distributor of the deficiency.

6.       TERM AND TERMINATION

         a.       Term. This Agreement commences on the date of the last
signature hereto or the first commercial distribution of the Service, whichever
occurs first (the "Effective Date"), and shall remain in effect for the Initial
Term set forth in Exhibit A. This Agreement shall renew automatically for
successive periods of the duration of the Renewal Term set forth in Exhibit A,
unless either party notifies the other party in writing, at least ninety (90)
days before the end of the Initial Term or any Renewal Term, of its election
not to renew.

         b.       Termination. Either party may terminate this Agreement at any
time if the other party materially breaches any provision of this Agreement.

termination which identifies the breach, or (ii) if the breach, capable of
being cured, has not been cured within sixty (60) days after receipt of written
notice from the non-breaching party identifying the breach, then immediately
upon receipt of a written notice of termination received within thirty (30)
days of the end of such sixty (60) day period. For purposes of this paragraph,

15, 16 and 17 of this Agreement shall survive termination of this Agreement.

7.       CONFIDENTIAL INFORMATION

         a.       Definition. "Confidential Information" shall mean information
which is designated as Confidential Information by the party disclosing such
information (the "Disclosing Party") (i) in Exhibit C to this Agreement, (ii)
with respect to information provided on paper, by facsimile or electronic mail,
on magnetic media, electronically or by any other medium (collectively "in
writing"), by labeling such information as "CONFIDENTIAL INFORMATION" before
the information is provided to the other party (the "Receiving Party"), or
(iii) with respect to information disclosed either verbally or in writing, by
notifying the Receiving Party, in writing within thirty (30) days of the
disclosure, that the information identified in such notice is designated
Confidential Information effective as of the Receiving Party's receipt of such
written notice.

         b.       Exclusions. "Confidential Information" shall not include
information that (i) is or shall become generally available without fault of
the Receiving Party, (ii) is in the Receiving Party's possession prior to its
disclosure by the Disclosing Party, (iii) is independently developed by the
Receiving Party, or (iv) is rightfully obtained by the Receiving Party from

take all reasonable precautions to prevent inadvertent disclosure of such
Confidential Information. Except as necessary to perform under this Agreement,
the Receiving Party shall not use or copy Confidential Information of the
Disclosing Party, without first obtaining the Disclosing Party's consent, and
will take all reasonable precautions to prevent inadvertent use and copying of
such Confidential Information.

         d.       Injunctive Relief Exclusion of Liability Limitation. The
parties agree that damages shall be an inadequate remedy in the event of a
breach by either party of this paragraph and that any such breach by a
Receiving Party will cause the Disclosing Party great and irreparable injury
and damage. Accordingly, a party shall be entitled, without waiving any
additional rights or remedies otherwise available at law or in equity or by
statute, to injunctive and other equitable relief in the event of a breach or
intended or threatened breach of this paragraph. The provisions of Paragraph 13
shall not apply to any breach of this Paragraph 7.
