                                                         --------  -------
the failure of any indemnified party to give timely notice shall not affect
rights to indemnification hereunder except to the extent that the indemnifying
party demonstrates actual damage caused by such failure. After such notice, if
the indemnifying party shall acknowledge in writing to the indemnified party
that the indemnifying party shall be obligated under the terms of its indemnity
hereunder in connection with such Action or Proceeding, then the indemnifying
party shall be entitled, if it so elects, to take control of the defense and
investigation of such Action or Proceeding and to employ and engage attorneys of
its own choice to handle and defend the same, such attorneys to be reasonably
satisfactory to the indemnified party, at the indemnifying party's cost, risk
and expense (unless (i) the indemnifying party has failed to assume the defense
of such Action or Proceeding or (ii) the named parties to such Action or
Proceeding include both of the indemnifying party and the indemnified party, and
the indemnified party and its counsel determine in good faith that there may be
one or more legal defenses available to such indemnified party that are
different from or additional to those available to the indemnifying party and
that joint representation would be inappropriate), and to compromise or settle
such Action or Proceeding, which compromise or settlement shall be made only
with the written consent of the indemnified party, such consent not to be
unreasonably withheld. The indemnified party may withhold such consent if such
compromise or settlement would adversely affect the conduct of business or
requires less than an unconditional release to be obtained. If (i) the
indemnifying party fails to assume the defense of such Action or Proceeding
within fifteen (15) days after receipt of notice thereof pursuant to this
Section 8.2, or (ii) the named parties to such Action or Proceeding include both
- -----------
the indemnifying party and the indemnified party and the indemnified party and
its counsel determine in good faith that there may be one or more legal defenses
available to such indemnified party that are different from or additional to
those available to the indemnifying party and that joint representation would be
inappropriate, the indemnified party against which such Action or Proceeding has
been filed or initiated will (upon delivering notice to such effect to the
indemnifying party) have the right to undertake, at the indemnifying party's
cost and expense, the defense, compromise or settlement of such Action or
Proceeding on behalf of and for the account and risk of the indemnifying party;
provided, however, that such Action or Proceeding shall not be compromised or
- --------  -------
settled without the written consent of the indemnifying party, which consent
shall not be unreasonably withheld. In the event the indemnified party assumes
defense of the Action or Proceeding, the indemnified party will keep the
indemnifying party reasonably informed of the progress of any such defense,
compromise or settlement and will consult with, when appropriate, and consider
any reasonable advice from, the indemnifying party of any such defense,
compromise or settlement. The indemnifying party shall be liable for any
settlement of any action effected pursuant to and in accordance with this
Section 8.2 and for any final judgment (subject to any right of appeal), and the
- -----------
indemnifying party agrees to indemnify and hold harmless the indemnified party
from and against any Damages by reason of such settlement or judgment.

               Subject to the limitations set forth in Section 8.2(d) below,
                                                       --------------       
regardless of whether the indemnifying party or the indemnified party takes up
the defense, the indemnifying party will pay reasonable costs and expenses in
connection with the defense, compromise or settlement for any Action or
Proceeding under this Section 8.2.
                      ----------- 

                                       22

 
               The indemnified party shall cooperate in all reasonable respects
with the indemnifying party and such attorneys in the investigation, trial and
defense of such Action or Proceeding and any appeal arising therefrom; provided,
                                                                       --------
however, that the indemnified party may, at its own cost, participate in the
- ------- 
investigation, trial and defense of such Action or Proceeding and any appeal
arising therefrom. The indemnifying party shall pay all expenses due under this
Section 8.2 as such expenses become due.  In the event such expenses are not so
- -----------

under this Section 8.2 without the consent of the indemnifying party and without

and procedures of the American Arbitration Association before a panel of three
arbitrators. The ruling of the arbitrator shall be final, and judgment thereon

     of the Rules, except that the AAA will transmit the list within ten days
     of the filing of the Demand for Arbitration, and the Parties will have
     five days to return the list to the AAA with their objections and
     preferences. Discovery will be limited to no more than two depositions by
     each side and written document requests, requesting the production of
     specific documents. The Parties will voluntarily produce any and all
     documents that they intend to use at the hearing before the close of

GENERAL TERMS AND CONDITIONS (76009.1)                            Page 5 of 4

 
      discovery, subject to supplementation for purposes of rebuttal or good
      cause shown. The period for taking discovery will be 60 days, commencing
      upon the day that the answer is due under the Rules. The arbitrator will
      hold a pre-hearing conference within three days of the close of discovery
      and will schedule the hearing within 30 days of the close of discovery.
      Prior to the selection of the arbitration, nothing in this Agreement will
      prevent the Parties from applying to a court that would otherwise have
      jurisdiction for provisional or interim injunctive other equitable
      measures. After the arbitral panel is selected, it will have sole
      jurisdiction to hear such applications, except that any measure ordered by
      the arbitrator may be immediately and specifically enforced by a court
      otherwise having jurisdiction over the Parties. Each party will pay its
      own fees and costs associated with the Arbitration. Each party will pay
      one-half the estimated arbitrator's fees up front and if either party
      fails to do so a default will be entered against such party. The Parties
      submit to the exclusive jurisdiction of any court sitting in the County of
      San Diego, State of California, for the resolution of any dispute or
      enforcement of any right arising out of or relating to this Section 23,
                                                                  ----------
      and waive any objection to the venue or personal jurisdiction of said
      courts. The Parties agree that the arbitrator will be entitled to award to
      COMPS, for each breach by Customer of any provisions of this Agreement,
      actual damages according to proof, liquidated damages in accordance with
      Section 21, or statutory damages for copyright infringement in accordance
      ----------
      with the U.S. Copyright Act, at COMPS' election.

24.   ENTIRE AGREEMENT.  These terms and conditions (and any Subscription 
      Licensing Agreement, if applicable) constitute the entire agreement
      between the parties and supersede all prior agreements, whether oral or
      written, which have been entered into before execution of these terms and
      conditions.

25.   REQUIREMENT OF A WRITING.  Copies and facsimiles of signed originals of 
      these terms and conditions and of orders will be as binding on Customer as
      originals. Orders Placed by Customer regardless of communication method
      and accepted by COMPS will be binding on Customer.

26.   CONSTRUCTION RULES.  If any term or provision of these terms and 
      conditions is held to be to extent invalid or otherwise unenforceable by
      any court of' competent jurisdiction, such provision will be construed as
      if it were written so as to effectuate to the greatest possible extent the
      parties' expressed intent, and in every case the remainder of these terms
      and conditions will not be affected thereby and will remain valid and
      enforceable. Typographical and clerical errors are subject to correction.

27.   NOTICES.  Any notice or communication provided for pursuant to these terms
      and conditions will be in writing and will be deemed given and received
      (a) upon delivery, if personally delivered or by facsimile transmission
      with receipt acknowledged, (b) one business day after having been
      deposited for overnight delivery with a well-recognized overnight courier
      or (c) three business days after deposit in U.S. mail when sent by
      registered or certified mail, postage prepaid, with proof of delivery at
      the address for such party previously provided to the other party by such
      party.

28.   FORCE MAJEURE.  COMPS' performance under these terms and conditions will 
      be suspended and excused to the extent that COMPS is hindered or prevented
      from performance for causes beyond COMPS' control including, but not
      limited to, events of force majeure.

29.   AMENDMENTS & WAIVERS.  No modification or waiver of these terms and
      conditions will be binding on either party unless in writing and executed
      by the duly authorized officer of COMPS and by a duly authorized
      representative of Customer. The waiver by any party of any specific breach
      will not operate or be construed as a waiver of any preceding,
      contemporaneous or succeeding breach or as a continuing waiver. No failure
      or delay by a party in exercising any right, power, or privilege under
      these terms and conditions or other conduct by a party will operate as a
      waiver, and no single or partial exercise thereof will preclude the full
      exercise or further exercise of any right, power, or privilege.

30.   BINDING AGREEMENT.  These terms and conditions will only be effective and
      enforceable against COMPS when executed by a duly authorized
      representative of COMPS if unmodified or by the Chairman or President of
      COMPS if modified at COMPS' principal offices in San Diego, California.
      These terms and conditions are binding on the Customer and all successors,
      permitted assigns, agents, representatives, and employees of Customer.

31.   SURVIVAL.  The parties' rights and obligations which by their nature would
      extend beyond the termination, cancellation, or expiration of any
      agreement between the parties or these terms and conditions, will survive
      such termination, cancellation or expiration.

32.   ASSIGNMENT.  Customer will not assign any benefit under any agreement with
      COMPS or these terms and conditions without COMPS' written consent, which
      will, if given, be on such terms as COMPS deems to be appropriate.
