filed on February 5, 1996.

filed on September 7, 2000.
D. No. 5,991,738 (“the ’738 patent”), which is derived from a patent application

2. On or about September 7, 2001, NMI filed a lawsuit against InfoSpace and
E-Commerce (collectively, “Defendants”), in the United States District Court for
the District of Arizona (the “Court”), Case No. CIV 01-441-TUC-RCC (the
“Action”), alleging infringement by Defendants of the ’737, ’917 and ’584
patents (collectively, “Patents Asserted”), and Defendants have answered,
denying any liability and asserting counterclaims.

3. Authorize.Net was a wholly-owned subsidiary of InfoSpace at the time the
Action was filed and provides products and services alleged by NMI to infringe
the Patents Asserted.

4. Authorize.Net sells its products and services directly and also indirectly
through resellers and other third parties.

successor of E-Commerce Exchange, LLC, a California limited liability company
and was incorrectly named and sued in the Action as E-Commerce Exchange, LLC.
E-Commerce markets and sells, as a reseller and also indirectly through sales
representatives and other third parties, products and services alleged by NMI to
infringe the Patents Asserted.

7. The Parties wish to compromise, resolve and settle the Action and the
disputes among them in order to avoid the delay, expense, inconvenience and
uncertainty of further litigation.

8. Each of Authorize.Net, Lightbridge and E-Commerce desires to obtain the
license, release and covenant set forth herein, and InfoSpace desires to obtain
the release and covenant set forth herein.

Accordingly, in consideration of the mutual covenants and promises set forth
