                                   RECITALS

A.   SEARCH, KL and InfoSpace are parties to that certain Amended and Restated
     Contract Provider Agreement dated August 24, 1998, and effective as of
     April 25, 1998 (as the same may have been amended to date, the "Advertising
     Agreement").

B.   SEARCH and KL are hereinafter referred to herein singly and collectively as
     "USSEARCH."

C.   USSEARCH and InfoSpace are each singly referred to herein sometimes as a
     "Party", and sometimes collectively as the "Parties."

D.   The Parties wish to cancel the Advertising Agreement effective as of the
     close of business on October 1, 2000 and to release any and all claims
     that either Party may have against the other Party arising out of or in
     connection with the Advertising Agreement, all effective as of the date
     hereof and all in accordance with the terms and conditions hereof.


                                   AGREEMENT

<PAGE>

2.   Mutual Releases.

     Each Party (the "Releasing Party") hereby forever releases, waives,
discharges and acquits the other Party and such other Party's respective
officers, directors, employees, principals, shareholders, agents, trustees,
servants, successors and assigns (singly and collectively, the "Released Party")
from and against the following (collectively, the "Released Claims"): any and
all claims, demands, obligations, liabilities, suits, causes of action, damages,
costs, losses or expenses of every type, kind, nature or description (including,
without limitation, attorneys' fees and disbursements) (collectively, "Claims"),
whether known or unknown, suspected or unsuspected, which arise out of or in
connection with the Advertising Agreement, including, without limitation, any
default or breach by the Released Party of any of its representations,
warranties, covenants or agreements thereunder.  However, this mutual release
does not apply to monies due InfoSpace by USSearch for services rendered by
InfoSpace through September 30, 2000.

3.   General Release Provisions.

     3.1  Waiver of Unknown Claims.  The Parties intend that the releases in
          ------------------------
Section 2  hereof shall be effective as a full and final accord and satisfaction
of (and as a bar to) all Released Claims, whether or not now known or suspected.
With respect to the Released Claims, the Parties acknowledge and waive the
provisions of Section 1542 of the California Civil Code, which provides as
follows:

          A general release does not extend to claims which the creditor does
not know or suspect to exist in his favor at the time of executing the release,
which if known by him must have materially affected his settlement with the
debtor.

The Parties have been fully advised of, and understand the purpose and effect
of, Section 1542, and acknowledge that the release of known and unknown Claims
provided herein constitutes a material aspect of the consideration being
exchanged.  The Parties agree to waive any and all rights which they may have
under Section 1542 or any other state or federal statute or common law principle
of similar effect which restricts the release of any such unknown Claims.

     3.2  Other Facts.  Each Party has made such investigation of the facts
          -----------
pertaining to this Agreement and the Released Claims as such Party deems
necessary.  The Parties understand that the facts with respect to any matter
included in the Released Claims may hereafter be found to be other than, or
different from, the facts now believed by the Parties to be true, and events may
occur in the future that change the Parties' current perception of damages or
the strengths or weaknesses of their respective Claims or cases.  The Parties
expressly accept and assume the risk of such possible difference in facts and
agree that this Agreement will become and remain effective notwithstanding such
different facts.

     3.3  Covenant Not to Sue.  Effective as of the date hereof, each Releasing
          -------------------
Party shall not assert (or continue to assert) in any court or other procedural
form or forum, whether initially or by way of defense, offset, or cross-,
counter- or third-party claim, or otherwise, any Released
<PAGE>

Claim that such Releasing Party has released, against the Released Party. Each
Releasing Party shall indemnify, hold harmless and defend (with counsel
reasonably satisfactory to the indemnified Released Party) the Released Party
against any Released Claim brought by (a) any person or entity (collectively,
"Person") against the Released Party by reason of the Releasing Party's
assertion of a Released Claim whether based upon subrogation, contribution,
indemnity or any other legal theory whatsoever, or (b) any Person acting or
asserting, by, under or through the Releasing Party.

     3.4  No Prior Transfer of Released Claims.  Each Releasing Party represents
          ------------------------------------
and warrants that (a) no Released Claim released by such Releasing Party has
been or will be transferred, hypothecated, assigned, subrogated or otherwise
given away by such Releasing Party to any Person; and without limiting the
generality of the foregoing, (b) no insurance company or other Person has the
right to assert any Released Claim against a Released Party released herein
therefrom as a subrogee of the Releasing Party.  Each Releasing Party shall
indemnify, hold harmless and defend (with counsel reasonably acceptable to the
indemnified Released Party) such Released Party from and against any Claim that
(if true or prevailing in litigation) would constitute a breach of the
representations and warranties made by the representing Party in this Section
3.4.

     3.6  Exceptions.  Notwithstanding anything to the contrary expressed or
          ----------
implied in Section 3.3 or elsewhere herein: (a) the Released Claims and the
releases and covenant not to sue granted in this Agreement do not extend to, and
nothing in this Agreement will be construed to limit, a Party's right to enforce
this Agreement according to its terms, or the right of either Party to enforce
either that certain Sales Agreement between the Parties dated as of the date
hereof (the "Sales Agreement") or the Warrant or the Registration Rights
Agreement (as defined below) or the documents executed pursuant to either of
them according to their terms; and (b) the Released Claims do not include any
Claim arising out of, or in connection with, a breach by a Party of its
obligations hereunder or under the Sales Agreement or the Registration Rights
Agreement or under the documents executed pursuant to any of such agreements.

     3.6  No Admission.  Nothing contained herein shall be construed as an
          ------------
admission by a Party of any liability or of any contention or allegation made by
another Party or Person.

4.   Additional Consideration to InfoSpace.

     In addition to the other promises given by USSEARCH to InfoSpace hereunder,
InfoSpace shall receive as consideration for its execution, delivery and
performance of this Agreement, the fully vested Warrant evidenced by the form of
Warrant To Purchase Shares of Common Stock attached hereto as Exhibit A (the
"Warrant") and a Registration Rights Agreement in the form of that attached
hereto as Exhibit B, which Warrant and Registration Rights Agreement USSEARCH
shall execute and deliver to InfoSpace concurrently with the Parties' execution
and delivery of this Agreement to one another.
