     3.34  Investment Representations. Each Seller is an "accredited investor"
           --------------------------
within the meaning of the Securities Act. Seller is aware that the COMPS
Securities issuable pursuant to this Agreement have not been registered under
the Securities Act or any applicable state securities laws, and agrees that the
COMPS Securities will not be offered or sold in the absence of registration
under the Securities Act and any applicable state securities laws or an
exemption from the registration requirements of the Securities Act and any
applicable state securities laws, which shall be accompanied by an opinion of
counsel to such Seller satisfactory to COMPS and its counsel that registration
of such securities is not required. Each Seller agrees not to transfer the COMPS
Securities in violation of the provisions of any applicable federal or state
securities laws. In this connection, each Seller represents that he, she or it
is familiar with Rule 144 and Rule 145 promulgated by the SEC pursuant to the
Securities Act, as presently in effect, and understands the resale limitations
imposed thereby and by the Securities Act. Each Seller understands that the
offering and sale of the COMPS Securities is intended to be exempt from

                                     -21-


registration under the Securities Act, by virtue of the private placement
exemption provided by Rule 505 and/or 506 of Regulation D promulgated under the
Securities Act and/or Section 4(2) of the Securities Act, based, in part, upon
the representations, warranties and agreements contained in this Agreement, and
COMPS may rely on such representations, warranties and agreements in connection
therewith. Each Seller is acquiring the COMPS Securities for his, her or its own
account and for investment, and not with a view to the distribution thereof or
with any present intention of distributing or selling any of the COMPS
Securities except in compliance with the Securities Act. Each Seller represents
that by reason of his, her or its business and financial experience, and the
business and financial experience of those persons, if any, retained by such
Seller to advise him, her or its with respect to his, her or its investment in
the COMPS Securities, each Seller together with such advisors have knowledge,
sophistication and experience in business and financial matters as to be capable
of evaluating the merits and risk of the prospective investment. The financial
condition and investments of each Seller are such that such Seller is in a
financial position to hold the COMPS Securities for an indefinite period of time
and to bear the economic risk of, and withstand a complete loss of, his
investment in the COMPS Securities. Each Seller has carefully examined this
Agreement and all exhibits and schedules thereto and the COMPS SEC Filings. Each
Seller acknowledges that COMPS has made available to him, her or it all
documents and information that such Seller has requested relating to COMPS and
has provided answers to all of such Seller's questions concerning COMPS and/or
the COMPS Securities. In evaluating the suitability of the acquisition of the
COMPS Securities hereunder, no Seller has not relied upon any representations or
other information (whether oral or written) other than as set forth in the COMPS
SEC Filings or as contained herein.

     3.35  Net Assets. Net Assets ("Net Assets") for May 31 1999 and as of the
           ----------
Closing Date is calculated as assets less liabilities as described in the May
31, 1999 balance sheet attached hereto (the "May 31 Balance Sheet"). The May 31
Balance Sheet is true, complete and accurate. The calculation of the Net Assets
as of the Closing Date will be based on an accounting basis consistent with the
May 31 Balance Sheet; specially, there shall be no adjustments for unearned
revenue, federal or Texas franchise taxes, or accrued annual leave. The
Stockholder agrees that there shall be an adjustment to the Purchase Price if
the Net Assets as the Closing Date is less than Six Thousand Seven Hundred and
Nine Dollars ($6,709). Such purchase price adjustment shall be in the form of an
offset against the Promissory Note.

more than Ten Thousand Dollars ($10,000) for the same period from the net income
(cash basis adjusted) described in the audited version of the Interim Financial
Statements (the "Audited Net Income") to be delivered within thirty (30) days
following the Closing. In the event the Pre-audited Net Income is less than the
Audited Net Income by more than Ten Thousand Dollars ($10,000), the Stockholder
shall be obligated to indemnify COMPS pursuant to Section 5.2 below for an
                                                  -----------
amount equal the product of (i) five (5) times the difference between such Pre-
audited Net Income and the Audited Net Income, multiplied by (ii) two (2). This
                                               ----------
product represents the annualized result.

such power and authority or to hold such license, permit or authorization would

           ------------------
corporate authority and has taken all corporate actions necessary to enter into
this Agreement, to consummate the transactions contemplated hereby and to

therein, in light of the circumstances in which they were made, not misleading,
except to the extent corrected by a document subsequently filed with the SEC.
The financial statements of COMPS, including the notes thereto, included in the
SEC Document comply as to form in all material respects with applicable
accounting requirements and with the published rules and regulations of the SEC
with respect thereto, have been prepared in accordance with GAAP consistently

          ---------------

          (a)  By Sellers.  Sellers shall jointly and severally, indemnify,
               ----------
defend and hold harmless COMPS, and its officers, directors, employees, agents,
successors and assigns (collectively the "COMPS Group") from and against any and
all costs, losses (including, without limitation, diminution in value),
Liabilities, damages, lawsuits, deficiencies, claims and expenses, including

representation, warranty or agreement or the inaccuracy of any representation,
made by Sellers in or pursuant to this Agreement, or in the other documents
delivered in connection with the transactions contemplated in this Agreement,
(ii) any breach of any covenant, representation, warranty or agreement relating
to the Business or CBN or the inaccuracy of any representation relating to the

               --------
Sellers and their officers, employees, agents, successors and assigns from and
against any and all Damages incurred in connection with, arising out of,

                                     -24-


any covenant, representation, warranty or agreement or the inaccuracy of any
representation, made by COMPS in or pursuant to this Agreement.

     (c)  Defense of Claims.  If any Action or Proceeding is filed or initiated
          -----------------
against any party entitled to the benefit of indemnity hereunder, written
notice thereof shall be given to the indemnifying party as promptly as
practicable (and in any event within ten (10) days after the service of the
citation or summons); provided, however, that 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 5.2, 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 5.2 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.

                                     -25-


               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 5.2.
                         -----------

               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 5.2 as such expenses become due.  In the event such expenses are not so
- -----------
paid, the indemnified party shall be entitled to settle any Action or Proceeding
under this Section 5.2 without the consent of the indemnifying party and without
           -----------
waiving any rights the indemnified party may have against the indemnifying
party.

          (d)  Limitation on Indemnification
               -----------------------------
               (i)   Sellers shall have no liability to any member of the COMPS
Group, and COMPS shall have no liability to Sellers, for amounts payable

                                                                 -----------
until the total of all Damages incurred by the indemnified party (i) exceeds Ten
Thousand Dollars ($10,000) with respect to Section 3.36 only and (ii) exceeds
                                           ------------
Twenty Five Thousand Dollars ($25,000) in the aggregate for all other Damages
(collectively the "Threshold Amount"), and then indemnification by the
indemnifying party shall apply to all such Damages including the Threshold
Amount;

               (ii)  Sellers shall have no liability to any member of the COMPS
Group, and COMPS shall have no liability to Sellers, pursuant to their
respective indemnification obligations in this Section 5.2 to the extent that
                                               -----------
the total of all Damages paid by the indemnifying party pursuant to such
indemnification obligations exceeds Three Hundred Eighty-Four Thousand Eight
Hundred Forty-Six Dollars ($384,846) in the aggregate; and

               (iii) The limitation on COMPS' indemnification obligation in this
Section 5.2(d) shall not apply to any fraud or intentional breach by COMPS of
- --------------
any representation, warranty, covenant or agreement or obligation of COMPS. The
limitation on the Sellers' indemnification obligation in this Section 5.2(d)
                                                              --------------
shall not apply to (i) any fraud or intentional breach by Sellers of any
representation, warranty, covenant or agreement or obligation of Sellers, (ii)
any breach of the representations and warranties by Sellers in Sections 3.18 and
                                                               -------------
3.35 and (iii) any discrepancies in the calculation of the account receivables
- ----
stated in the Interim Financial Statements and the account receivables stated in
the Financial Statements. The limitation on Sellers' indemnification obligation
in Section 5.2(d)(ii) shall not apply to any breach of the representations and
   ------------------
warranties by Sellers in Section 3.36.
                         ------------

     5.3  Offset.
          ------

          (a)  In addition to any other rights and remedies available to COMPS
herein, COMPS shall have the right to offset any amounts to which it may be
entitled under Section 5.2 above against (i) the Holdback Amount and (ii)
               -----------
amounts otherwise payable under the ARA-D/FW Promissory Note (collectively the
"Offset Amount"). If COMPS elects to offset any

                                     -26-


Offset Amount against the Holdback Amount or the ARA-D/FW, Promissory Note,
COMPS shall promptly notify the Company in writing (the "Offset Notice") by
certified mail (return receipt requested) or by a nationally recognized
overnight courier service (e.g., Federal Express) of the amount, nature and
basis of the offset. In the event the Company disputes COMPS' offset, the
Company shall notify COMPS of the dispute in writing (the "Dispute Notice") by
certified mail (return receipt requested) or a nationally recognized overnight
courier service within ten (10) days of COMPS' mailing of the Offset Notice. If
no Dispute Notice is given within such ten (10) day period, the COMPS offset
described in the Offset Notice shall be deemed agreed between the parties and
the Offset Amount offset against the Holdback Amount or the ARA-D/FW Promissory
Note shall be subtracted from the Holdback Amount or the outstanding principal
balance of the ARA-D/FW Promissory Note, as the case may be, at such time. In
the event a Dispute Notice is timely delivered to COMPS, COMPS and the Company
shall first use their best efforts to resolve such dispute among themselves
within ten (10) days following COMPS' receipt of the Dispute Notice. If COMPS
and the Company are unable to resolve the dispute within such ten (10) day
period, COMPS and the Company agree to settle the dispute by binding
arbitration, in accordance with Section 6.10 below In the event of a dispute,
                                ------------
the Offset Amount to be offset and all interests accrued thereon shall not be
released to the Company pursuant to Section 2.4(b) hereof (and the terms of the
                                    --------------
ARA-D/FW Promissory Note), but shall be held by COMPS until such dispute is
resolved.

         (b)  The exercise of an offset by COMPS pursuant to Section 5.3(a)
                                                              --------------
above, whether or not ultimately determined to be justified, will not constitute
an event of default under the ARA-D/FW Promissory Note or any instrument
securing the ARA-D/FW Promissory Note. Neither the exercise of nor the failure
to exercise such right of offset will constitute an election of remedies or
limit COMPS in any manner in the enforcement of any other remedies that may be
available to it.

     5.4  Further Assurances. In case at any time after the Closing any further
          ------------------
action is necessary or desirable to carry out the purposes of this Agreement,
each of the parties will take such further action (including the execution and
delivery of such further instruments and documents) as the other party
reasonably may request, all the sole cost and expense of the requesting party
(unless the requesting party is entitled to indemnification therefor under this
Article 5).

     5.5  Restricted Securities. (a) Transfer of this Note or Securities on
          -----------------------------------------------------------------
Conversion Thereof. With respect to any proposed offer, sale, assignment or
- ------------------
other disposition of the Promissory Note or securities into which the Promissory
Note may be converted, the Company will provide (i) written notice to COMPS
prior thereto, describing briefly the proposed offer, sale or other disposition,
(ii) a written opinion of the Company's counsel, reasonably satisfactory to
COMPS and accompanied by such supporting documents as COMPS may reasonably
request, to the effect that such offer, sale or other distribution may be
effected without registration or qualification (under any federal or state law
then in effect) and (iii) the party acquiring the Promissory Note has agreed in
writing for the benefit of COMPS to be bound by the terms of the Promissory
Note. Promptly upon receiving the foregoing, COMPS as promptly as practicable,
shall notify the Company whether the Company may sell or otherwise dispose of
this Promissory Note or such securities, all in accordance with the terms of the
notice delivered to COMPS. If a determination has been made pursuant to this
Section 5.5 that the opinion of counsel for the Company is not reasonably
- -----------
satisfactory to COMPS or the party acquiring the Promissory Note

                                     -27-


has not agreed to be bound by the terms of the Promissory Note, COMPS shall so
notify the Company promptly after such determination has been made. The
Promissory Note thus transferred and each certificate representing the
securities thus transferred shall bear the legends set forth in below. COMPS
shall be entitled to issue stop transfer instructions to its transfer agent in
connection with such restrictions.

          (b)  No Stockholder Rights. Nothing contained in this Agreement or the
               ---------------------
Promissory Note shall be construed as conferring upon the Company or any other
person the right to vote or to consent or to receive notice as a stockholder in
respect of meetings of stockholders for the election of directors of COMPS or
any other matters or any rights whatsoever as a stockholder of COMPS; and no
dividends or interest shall be payable or accrued in respect of the Promissory
Note or the interest represented hereby or the Common Stock into which the
Promissory Note is convertible until, and only to the extent that, the
Promissory Note shall have been converted.

          (c)  Legends. The Company understands that the Promissory Note and the
               -------
certificates evidencing the Securities issuable under the Promissory Note may

                                     -30-


and agreements among the parties with respect to the subject matter hereof and
contains the sole and entire agreement among the parties hereto with respect
thereto.

     6.3  Waiver. Any term or condition of this Agreement may be waived at any
          ------
time by the party that is entitled to the benefit thereof, but no such waiver
shall be effective unless set forth in a written instrument duly executed by or
on behalf of the party waiving such term or condition. No waiver by any party

shall be deemed to be or construed as a waiver of the same or any other term or

alternative.

     6.4  Amendment. This Agreement may be amended, supplemented or modified

only by a written instrument duly executed by or on behalf of each party hereto.

     6.5  No Third Party Beneficiary. The terms and provisions of this Agreement

are intended solely for the benefit of each party hereto and their respective
successors or permitted assigns, and it is not the intention of the parties to

Person entitled to indemnity under Section 6.5.
                                   -----------

     6.6  No Assignment; Binding Effect. Neither this Agreement nor any right,
          -----------------------------
interest or obligation hereunder may be assigned by any party hereto without the
prior written consent of the other parties hereto and any attempt to do so will
be void, except that any party's rights to indemnification under Article 5 may
                                                                 ---------
be freely assigned. This Agreement is binding upon, inures to the benefit of and
is enforceable by the parties hereto and their respective successors and
assigns.

     6.7  Headings. The headings used in this Agreement have been inserted for
          --------
convenience of reference only and do not define or limit the provisions hereof.

     6.8  Severability. If any provision of this Agreement is held to be
          ------------
illegal, invalid or unenforceable under any present or future law, and if the
rights or obligations of any party hereto under this Agreement will not be
materially and adversely affected thereby, (i) such provision will be fully
severable, (ii) this Agreement will be construed and enforced as if such
illegal, invalid or unenforceable provision had never comprised a part hereof,
(iii) the remaining provisions of this Agreement will remain in full force and
effect and will not be affected by the illegal, invalid or unenforceable
provision or by its severance herefrom and (iv) in lieu of such illegal, invalid
or unenforceable provision, there will be added automatically as a part of this
Agreement a legal, valid and enforceable provision as similar in terms to such
illegal, invalid or unenforceable provision as may be possible and mutually
acceptable to the parties herein.

     6.9  Governing Law. This Agreement shall be governed by and construed in
          -------------
accordance with the laws of the State of Texas applicable to contracts executed
and performed in such State, without giving effect to conflicts of laws
principles.

     6.10 Arbitration and Venue. Any controversy or claim arising out of or
          ---------------------
relating to this Agreement or the making, performance or interpretation thereof
shall be submitted to arbitration in San Diego, California, pursuant to the
rules and procedures of the American Arbitration Association before a panel of
three arbitrators. The ruling of the arbitrator shall be

                                     -31-


final, and judgment thereon may be entered in any court having jurisdiction. If
any question is submitted to a court of law for resolution, then the Superior
Court of the County of San Diego or the United States District Court having
jurisdiction in the County of San Diego shall be the exclusive court of
competent jurisdiction for the resolution of such question. Each party will bear
one half of the cost of the arbitration filing and hearing fees, and the cost of
the arbitrator. Each party will bear its own attorneys' fees, unless otherwise
decided by the arbitrator. The parties understand and agree that the arbitration
shall be instead of any civil litigation and that the arbitrator's decision
shall be final and binding to the fullest extent permitted by law and
enforceable by any court having jurisdiction thereof. Each party shall be
entitled to pre-hearing discovery as provided in California Code of Civil
Procedure Section 1283.05

     6.11  Consent to Jurisdiction and Forum Selection. The parties hereto agree
           -------------------------------------------
that all actions or proceedings arising in connection with this Agreement shall
be initiated and tried exclusively in the State and Federal courts located in
the County of San Diego, State of California. The aforementioned choice of venue
is intended by the parties to be mandatory and not permissive in nature, thereby
precluding the possibility of litigation between the parties with respect to or
arising out of this Agreement in any jurisdiction other than that specified in
this Section 6.11. Each party hereby waives any right it may have to assert the
     ------------
doctrine of forum non conveniens or similar doctrine or to object to venue with
respect to any proceeding brought in accordance with this paragraph, and
stipulates that the State and Federal courts located in the County of San Diego,
State of California shall have in personam jurisdiction and venue over each of
them for the purposes of litigating any dispute, controversy or proceeding
arising out of or related to this Agreement. Each party hereby authorizes and
accepts service of process sufficient for personal jurisdiction in any action
against it as contemplated by this Section 6.11 by registered or certified mail,
                                   ------------
return receipt requested, postage prepaid, to its address for the giving of
notices as set forth in this Agreement, or in the manner set forth in Section
                                                                      -------
6.1 of this Agreement for the giving of notice. Any final judgment rendered
- ---
against a party in any action or proceeding shall be conclusive as to the
subject of such final judgment and may be enforced in other jurisdictions in any
manner provided by law.

     6.12  Expense. Except as otherwise provided in this Agreement, the Sellers
           -------
and COMPS shall pay their own expenses and costs incidental to the preparation
of this Agreement and to the consummation of the transactions contemplated
hereby.

     6.13  Construction. No provision of this Agreement shall be construed in
           ------------
favor of or against any party on the ground that such party or its counsel
drafted the provision. Any remedies provided for herein are not exclusive of any
other lawful remedies which may be available to either party. This Agreement
shall at all times be construed so as to carry out the purposes stated herein.

     6.14  Counterparts. This Agreement may be executed in any number of
           ------------
counterparts and by facsimile, each of which will be deemed an original, but all
of which together will constitute one and the same instrument.
