     enhancements to the Elogic Enterprise Technology during any Renewal Period

     NewsEdge reserves the right to approve the assigned Elogic employees to
     ensure that the employees have the proper skill sets and training for the
     development of the Product, such approval to not be unreasonably withheld.
     NewsEdge understands that Elogic will need to rotate staff to enhance the

     such events.

     of the Elogic Enterprise Technology separate from the Product or in
     connection with distribution of the Product which does not generate Covered
     Revenue. The sales and marketing agreement will provide for a royalty

     as contemplated in Section B(2) below. NewsEdge shall have the right to
     annual optional renewals of the right to sublicense the Elogic Enterprise
     Technology for which (i) it will not be obligated to pay the minimum
     royalty described in

B.  ELOGIC RECEIVES:
--------------------

1.)  Guaranteed minimum annual (calendar year) royalty payments of $1.5 million
     to be applied against future earned royalties for the two (2) years of the
     development term, payable in $125,000 monthly installments. This $1.5
     million per year minimum royalty payment will be counted as an advance
     against the seven and one half percent (7.5%) annual royalty rate described
     in Section B(2) below. However, the previous year's minimum royalty payment
     shall not count towards any subsequent year.

     In the event of any Renewal under paragraph A(3) above, the annual
     guaranteed minimum annual royalty payments of $1.5 million will be applied
     against royalties during that Renewal Term according to the same mechanism
     as described in the above paragraph.

2.)  A royalty of seven and one half percent (7.5%) of Royalty Generating
     Revenue. "Royalty Generating Revenue" is all Covered Revenue in excess of
     eighty percent (80%) of the prior year's Covered Revenue (the "Revenue
     Floor"). "Covered Revenue" is all Enterprise Revenue excluding professional
     services and installation revenue (which for purposes of deductions from
     Enterprise Revenue, shall not be deemed to exceed 5% of Enterprise
     Revenue). "Enterprise Revenue" is all NewsEdge revenue other than
     NewsEdge's segmented Individual.com revenue. All earned royalties will be
     first paid with the advance royalties described in Section B(1) above. Any
     excess royalties during the two (2) year development term shall be paid
     within forty-five (45) days after each calendar year end; upon exercise by
     NewsEdge of any optional extension pursuant to Section A(5) above,
     royalties shall be determined quarterly rather than on an annual
     comparative basis and shall be paid within thirty (30) days after the end
     of each of NewsEdge's fiscal quarters.
