                                VOTING AGREEMENT

     THIS VOTING AGREEMENT (the "Agreement") is made and entered into this 19th
day of August, 2002, by and among The Bluebook International Holding Company, a
Delaware corporation (the "Company"), those certain existing holders of the
Company's Common Stock and Series B Convertible Preferred Stock listed on
Exhibit A hereto (the "Holders") and Cotelligent, Inc., a Delaware corporation
("Cotelligent").

                                   WITNESSETH

     WHEREAS, the Holders are the beneficial owners of shares of the Common
Stock and Series B Convertible Preferred Stock of the Company set forth opposite
their respective names on Exhibit A;

     WHEREAS, the Company proposes to sell shares of its Series C Preferred
Stock (the "Series C Preferred"), to Cotelligent pursuant to the Series C
Convertible Redeemable Preferred Stock Purchase Agreement dated as of August 19,
2002 (the "Financing"); and

     WHEREAS, in connection with the consummation of the Financing, the Holders
and Cotelligent have agreed to provide for the future voting of the Holders'
shares of the Company's capital stock as set forth below.

     NOW, THEREFORE, in consideration of the promises and for good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, the
parties hereto agree as follows:

                                    ARTICLE I

1. Voting.

     1.1 (a) During the term of this Agreement, the Holders each agree to vote
all shares of voting capital stock of the Company registered in their respective
names or beneficially owned by them as of the date hereof, and any and all other
securities of the Company legally or beneficially acquired by each of the
Holders after the date hereof, (hereinafter collectively referred to as the
"Holder Shares") subject to, and in accordance with, the provisions of this
Agreement.

     1.2 From and after the date hereof and continuing until the expiration or
earlier termination of this Agreement, at each election of all of the directors
(or the first election of any portion thereof and each subsequent election for
such portion), each Holder shall vote all of such person's Holder Shares for the
election as a director of one representative of Cotelligent designated by
written notice from Cotelligent to each Holder (the "Cotelligent Director"). Any
vote taken to remove the Cotelligent Director elected pursuant to this Section
1.2, or to fill any

                                       1

<PAGE>

vacancy created by the resignation or removal of the Cotelligent Director
elected pursuant to this Section 1.2, shall also be subject to the provisions of
this Section 1.2.

     1.3 The Holders represent and warrant to Cotelligent that there are no
voting agreements, voting trusts, or any other agreements or understandings that
affect or relate to the voting or giving of written consents with respect to the
Holder Shares, other than this Agreement.

     1.4 Concurrently with the execution of this Agreement, there shall be
imprinted or otherwise placed, on all certificates representing the Holder
Shares the following restrictive legend (the "Legend"):

          "THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO THE TERMS
          AND CONDITIONS OF A VOTING AGREEMENT WHICH PLACES CERTAIN RESTRICTIONS
          ON THE VOTING OF THE SHARES REPRESENTED HEREBY. ANY PERSON ACCEPTING
          ANY INTEREST IN SUCH SHARES SHALL BE DEEMED TO AGREE TO AND SHALL
          BECOME BOUND BY ALL THE PROVISIONS OF SUCH AGREEMENT. A COPY OF SUCH
          VOTING AGREEMENT WILL BE FURNISHED TO THE RECORD HOLDER OF THIS
          CERTIFICATE WITHOUT CHARGE UPON WRITTEN REQUEST TO THE COMPANY AT ITS
          PRINCIPAL PLACE OF BUSINESS."

     1.5 The Company agrees that, during the term of this Agreement, it will not
remove, and will not permit to be removed (upon registration, transfer,
reissuance or otherwise), the Legend from any such certificate and will place or
cause to be placed the Legend on any new certificate issued to represent Holder
Shares theretofore represented by a certificate carrying the Legend.

     1.6 The provisions of this Agreement shall be binding upon the successors
in interest to any of the Holder Shares. The Company shall not permit the
transfer of any of the Holder Shares on its books or issue a new certificate
representing any of the Holder Shares unless and until the person to whom such
security is to be transferred shall have executed a written agreement, pursuant
to which such person becomes a party to this Agreement or otherwise agrees to be
bound by all the provisions hereof as if such person were a Holder.

     1.7 Except as provided by this Agreement, each Holder shall exercise the
full rights of a shareholder with respect to the Holder Shares.

     1.8 The Company agrees to use its best efforts to ensure that the rights
granted hereunder are effective and that the parties hereto enjoy the benefits
thereof. Such actions include, without limitation, the use of the Company's best
efforts to cause the nomination and election of the director as provided above.
The Company will not, by any voluntary action, avoid or seek to avoid the
observance or performance of any of the terms to be performed hereunder by the
Company, but will at all times in good faith assist in the carrying out of all
of

                                       2

<PAGE>

the provisions of this Agreement and in the taking of all such actions as may be
necessary, appropriate or reasonably requested by Cotelligent in order to
protect the rights of Cotelligent hereunder against impairment.

                                   ARTICLE II

2. Termination.

     2.1 The term of this Agreement shall continue in full force and effect from
the date hereof through the earliest of the following dates, on which it shall
terminate in its entirety:

          (a) the date as of which the parties hereto terminate this Agreement
     by the written consent of Cotelligent, the Company and holders of a
     majority of the Holder Shares;

          (b) the date Cotelligent owns less than twenty percent (20%) of the
     "Conversion Shares" (as defined below) or one-third (1/3) of the Series C
     Preferred; or

          (c) the date James Lavelle is removed as the Chief Executive Officer
     of Cotelligent after a hostile takeover of Cotelligent.

Upon termination of this Agreement, no party shall have any further obligation
hereunder. As used herein "Conversion Shares" shall mean the initial shares of
the Company's common stock received upon conversion of any of the Series C
Preferred.

                                   ARTICLE III

3. Miscellaneous.

     3.1 The parties hereto hereby declare that it is impossible to measure in
money the damages which will accrue to a party hereto or to his heirs, personal
representatives, or assigns by reason of a failure to perform any of the
obligations under this Agreement and agree that the terms of this Agreement
shall be specifically enforceable. If any party hereto or his heirs, personal
representatives, successors or assigns institutes any action or proceeding to
specifically enforce the provisions hereof, any person against whom such action
or proceeding is brought hereby waives the claim or defense therein that such
party or such personal representative has an adequate remedy at law, and such
person shall not offer in any such action or proceeding the claim or defense
that such remedy at law exists.

     3.2 This Agreement, and the rights of the parties hereto, shall be governed
by and construed in accordance with the laws of the State of California.

     3.3 This Agreement may be amended and any term hereof may be waived only by
an instrument in writing signed by the Company, holders of at least a majority
of the Holder Shares and Cotelligent.

     3.4 If any provision of this Agreement is held to be invalid or
unenforceable, the validity and enforceability of the remaining provisions of
this Agreement shall not be affected thereby.

     3.5 Cotelligent may not assign any rights hereunder, except to a
successor-in-interest by merger or sale of substantially all the assets or stock
of Cotelligent. Subject to the foregoing, this Agreement shall inure to the
benefit of and be binding upon the parties hereto and their respective heirs,
successors, assigns, administrators, executors and other legal representatives.

     3.6 This Agreement may be executed in one or more counterparts, each of
which will be deemed an original but all of which together shall constitute one
and the same agreement.

     3.7 No waivers of any breach of this Agreement extended by any party hereto
to any other party shall be construed as a waiver of any rights or remedies of
any other party hereto or with respect to any subsequent breach.

     3.8 In the event that any suit or action is instituted to enforce any
provision in this Agreement, the prevailing party shall be entitled to all costs
and expenses of maintaining such suit or action, including reasonable attorneys'
fees.

     3.9 This Agreement constitutes the full and entire understanding and
agreement between the parties with regard to the subject matter of this
Agreement, and supersedes and replaces in all respects any and all prior voting
agreements.

                        RIGHT OF FIRST REFUSAL AGREEMENT

     This RIGHT OF FIRST REFUSAL AGREEMENT (the "Agreement") is entered into as
of August 19, 2002 by and among The Bluebook International Holding Company, a
Delaware corporation (the "Company"), Mark A. Josipovich, Daniel E. Josipovich,
Daniel T. Josipovich and Dorothy E. Josipovich (each a "Founder" and
collectively, the "Founders") and Cotelligent, Inc., a Delaware corporation (the
"Purchaser").

                                    RECITALS

     The Company and the Purchaser are parties to the Series C Preferred Stock
Purchase Agreement of even date herewith, pursuant to which the Purchaser is
purchasing shares of the Company's Series C Preferred Stock (the "Series C
Preferred");

     The Founders are the beneficial owners of the number of shares of Common
Stock set forth opposite each Founder's name on Schedule A hereto; and

     The Founders wish to provide further inducement to the Purchaser to
purchase the Series C Preferred by providing the Purchaser with a right of first
refusal to purchase the Founders' Common Stock as provided in this Agreement;

     NOW, THEREFORE, in consideration of the premises and the mutual promises
set forth in this Agreement;

     The parties agree as follows:

     1. Restrictions on Transfer of Shares by the Founders. Except as otherwise
provided in this Agreement, the Founders will not sell, assign, transfer,
pledge, hypothecate, or otherwise encumber or dispose of in any way, all or any
part of or any interest in the Equity Securities (as defined below) now or
hereafter owned or held by the Founders. Any sale, assignment, transfer, pledge,
hypothecation or other encumbrance or disposition of Equity Securities not made
in conformance with this Agreement shall be null and void, shall not be recorded
on the books of the Company and shall not be recognized by the Company.

     2. Definitions.

     Equity Securities. For purposes of this Agreement, the term "Equity
Securities" shall mean any securities having voting rights in the election of
the Board of directors of the Company not contingent upon default, or any
securities evidencing an ownership interest in the Company, or any securities
convertible into or exercisable for any shares of the foregoing, or any
agreement or commitment to issue any of the foregoing.

<PAGE>

     3. Agreements Among the Company, the Purchaser and the Founders.

          3.1 Rights of First Refusal.

               (a) Transfer Notice. If at any time any Founder proposes to
          transfer Equity Securities to one or more third parties pursuant to an
          understanding with such third parties (a "Transfer"), then such
          Founder shall give Purchaser written notice of the Founder's intention
          to make the Transfer (the "Transfer Notice"), which Transfer Notice
          shall include (i) a description of the Equity Securities to be
          transferred ("Offered Shares"), and (ii) the consideration and the
          material terms and conditions upon which the proposed Transfer is to
          be made. The Transfer Notice shall certify that the Founder has
          received a firm offer from the prospective transferee(s) and in good
          faith believes a binding agreement for the Transfer is obtainable on
          the terms set forth in the Transfer Notice. The Transfer Notice shall
          also include a copy of any written proposal, term sheet or letter of
          intent or other agreement relating to the proposed Transfer, subject
          to any obligation to keep the identity of the prospective transferee
          confidential.

               (b) Purchaser's Option. Purchaser shall have an option for a
          period of ten (10) days from receipt of the Transfer Notice to elect
          to purchase the Offered Shares at the same price and subject to the
          same material terms and conditions as described in the Transfer
          Notice. Purchaser may exercise such purchase option and, thereby,
          purchase all (or a portion of) the Offered Shares by notifying such
          Founder in writing before expiration of the such ten (10) day period.
          If Purchaser gives the Founder notice that it desires to purchase such
          shares, then payment for the Offered Shares shall be by check or wire
          transfer, against delivery of the Offered Shares to be purchased at
          the Company's principal place of business or such other place agreed
          upon between the parties and at the time of the scheduled closing
          therefor, which shall be no later than thirty (30) days after
          Purchaser's receipt of the Transfer Notice, unless the value of the
          purchase price has not yet been established pursuant to Section 3.1(c)
          below.

               (c) Valuation of Property. Should the purchase price specified in
          the Transfer Notice be payable in property other than cash or
          evidences of indebtedness, Purchaser shall have the right to pay the
          purchase price in the form of cash equal in amount to the value of
          such property. If such property does not have a readily ascertainable
          value, and if the Offered Shares are common stock or other Equity
          Securities sold on the public market, then the value of such property
          shall be deemed to be the value of such Offered Shares, which shall be
          equal to the average daily trading price over the ten (10) day period
          immediately preceding the date of the Transfer Notice. For any other
          Offered Shares, Founder and Purchaser shall use their best efforts to
          agree upon a value of such property within ten (10) days of
          Purchaser's receipt of the Transfer Notice. If the Founder and
          Purchaser cannot agree on such cash value within ten (10) days after
          Purchaser's receipt of the Transfer Notice, Founder and Purchaser
          shall mutually select an appraiser who is active in the appraisal of
          the type of property at issue within twenty (20) days after
          Purchaser's receipt of the Transfer Notice. Founder shall submit
          Founder's determination of value ("Founder's Value") and Purchaser
          shall submit Purchaser's determination of value ("Purchaser's Value")
          to such appraiser, at such time or times and in such manner as Founder
          and Purchaser shall agree (or as soon as possible as determined and
          directed by the appraiser if Founder and Purchaser do not promptly
          agree). The appraiser shall promptly (but in no event beyond ten (10)
          days) select either Founder's Value or Purchaser's Value as the fair
          value of the subject property, and such determination shall be binding
          on Founder and Purchaser. If Founder's determination is selected as

                                       2

<PAGE>

          the fair value of the property, then Purchaser shall bear all of the
          appraiser's costs and fees. If Purchaser's determination is selected
          as the fair value of the property, the Founder shall bear all of the
          broker's costs and fees. If the time for the closing of Purchaser's
          purchase has expired but for the determination of the value of the
          purchase price offered by the prospective transferee(s), then such
          closing shall be held on or prior to the fifth (5th) business day
          after such valuation shall have been made pursuant to this subsection.

          3.2 Non-Exercise of Rights. To the extent Purchaser has not exercised
     its rights to purchase all of the Offered Shares within the time periods
     specified in Section 3.1, the Founder shall have until the later of (1) the
     closing date set forth in the Transfer Notice, or (2) a period of sixty
     (60) days from the expiration of such rights in which to sell the Offered
     Shares not so purchased (the "Open Period") upon terms and conditions
     (including the purchase price) no more favorable than those specified in
     the Transfer Notice to the third-party transferee(s). The third-party
     transferee(s) shall acquire any such Offered Shares free and clear of
     subsequent rights of first refusal under this Agreement. In the event the
     Founder does not consummate the sale or disposition of all of the Offered
     Shares not purchased by Purchaser within the Open Period, Purchaser's first
     refusal rights shall continue to be applicable to any subsequent
     disposition of any of the Offered Shares by the Founder until such right
     lapses in accordance with the terms of this Agreement. Furthermore, the
     exercise or non-exercise of the rights of Purchaser under this Section 3 to
     purchase Equity Securities from the Founder shall not adversely affect its
     right to make subsequent purchases from the Founder of Equity Securities.

          3.3 Limitations to Rights of First Refusal. Notwithstanding the
     provisions of Section 3.1 of this Agreement, any Founder may sell or
     otherwise assign, with or without consideration, Equity Securities to
     either (i) the Founder's spouse, parent, sibling, child, or any of their
     lineal descendants (collectively, the "Immediate Family") or to a
     custodian, trustee (including a trustee of a voting trust), executor, or
     other fiduciary for the account of the Founder's Immediate Family, or to a
     trust for the Founder's own self or any partnership, limited liability
     company or corporation qualified under Subchapter "S" of the Internal
     Revenue Code beneficially owned solely by the Founder and/or the Immediate
     Family; provided that each such transferee or assignee, prior to the
     completion of the sale, transfer, or assignment shall have executed
     documents assuming the obligations of the applicable Founder or Founders
     under this Agreement with respect to the transferred securities; or (ii) to
     Microsoft, Cisco, KPMG or Hewlett Packard and their successors-in-interest
     by merger, division or sale of substantially all the assets or stock of any
     of the foregoing companies, which transfer shall be made free and clear of
     subsequent rights of first refusal under this Agreement.

          3.4 Failure to Close. In the event that Purchaser elects to purchase
     the Offered Shares within the time period specified in Section 3.1 above
     but fails to close such purchase within the time period specified therein,
     then Founder may seek any contract remedy it may have in such event,
     including specific performance.

     4. Assignments and Transfers; No Third Party Beneficiaries. Purchaser may
not assign any rights under this Agreement, except to a successor-in-interest by
merger or sale of substantially all of the assets or stock of Purchaser. Subject
to the foregoing, this Agreement and the rights and obligations of the parties
hereunder shall inure to the benefit of, and be binding upon, their respective
successors, assigns (except as provided in Section 3.3 above) and legal
representatives, but shall not otherwise be for the benefit of any third party.

                                       3

<PAGE>

     5. Legend. Each existing or replacement certificate for shares now owned or
hereafter acquired by a Founder shall bear the following legend upon its face

          SECURITIES REPRESENTED BY THIS CERTIFICATE IS SUBJECT TO THE TERMS AND
          CONDITIONS OF A CERTAIN RIGHT OF FIRST REFUSAL AGREEMENT BY AND
          BETWEEN THE STOCKHOLDER, THE CORPORATION AND CERTAIN PURCHASERS OF
          STOCK OF THE CORPORATION. COPIES OF SUCH AGREEMENT MAY BE OBTAINED
          UPON WRITTEN REQUEST TO THE SECRETARY OF THE CORPORATION."

     6. Effect of Change in Company's Capital Structure. The provisions of this
Agreement shall apply to any new or different shares issued to the Founders as
the result of a stock dividend, stock split, reverse stock split, combination,
reclassification or like change in the capital structure of the Company.

     7. Notices. Any notice required or permitted by any provision of this
Agreement shall be given in writing and shall be delivered personally or by

delivery shall be deemed received two (2) days after they have been so sent.

     8. Further Instruments and Actions. The parties agree to execute such
further instruments and to take such further action as may reasonably be
necessary to carry out the intent of this Agreement. The Founders agree to
cooperate affirmatively with the Company and Purchaser, to the extent reasonably
requested by the Company or Purchaser, to enforce rights and obligations
pursuant hereto.

     9. Term. This Agreement shall terminate upon (i) the mutual written consent
of the Company, Purchaser and each of the Founders, (ii) upon the transfer of
all the Equity Securities in accordance with this Agreement, or (iii) upon the
sale of all of the securities of the Company then held by Purchaser.

     10. Entire Agreement. This Agreement contains the entire understanding of
the parties hereto with respect to the subject matter hereof, supersedes all
other agreements between or among any of the parties with respect to the subject
matter hereof and cannot be altered or otherwise amended except pursuant to an
instrument in writing signed by each of the parties to this Agreement. This
Agreement shall be interpreted under the laws of the State of California without
