THIS WARRANT AND THE UNITS ISSUABLE HEREUNDER HAVE NOT BEEN REGISTERED UNDER THE
SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD, PLEDGED, OR OTHERWISE
TRANSFERRED WITHOUT AN EFFECTIVE REGISTRATION THEREOF UNDER SUCH ACT OR PURSUANT
TO RULE 144 OR AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE COMPANY AND
ITS COUNSEL, THAT SUCH REGISTRATION IS NOT REQUIRED.

                        WARRANT TO PURCHASE COMMON STOCK

         THIS WARRANT CERTIFIES THAT, for good and valuable consideration, Boyle
Consolidated Communications, L.L.C., a Tennessee limited liability company
("Holder") is irrevocably (subject to Article 3 and Section 5.1 hereof) entitled
to purchase up to Twenty Thousand (20,000) fully paid and nonassessable shares
of BLUESTAR PROPERTIES, INC. (the "Company") $.01 par value common stock (the
"Shares") at the price of Five Dollar ($5.00) per Share (the "Warrant Price"),
as adjusted pursuant to Article 2 of this Warrant, subject to the provisions and
upon the terms and conditions set forth in this Warrant.

                              ARTICLE 1. EXERCISE.

         1.1 Method of Exercise. Holder may exercise this Warrant by delivering
a duly executed Notice of Exercise in substantially the form attached as
APPENDIX 1 to the principal office of the Company. Holder shall also deliver to
the Company a check for the aggregate Warrant Price for the Shares being
purchased.

         1.2 No Rights as a Shareholder. This Warrant does not entitle Holder to
any voting rights as a Shareholder of the Company prior to the exercise hereof.

         1.3 Delivery of Certificate and New Warrant. Promptly after Holder
exercises this Warrant, the Company shall deliver to Holder a certificate for
the Shares acquired and, if this Warrant has not been fully exercised and has
not expired, a new Warrant representing the Shares not so exercised.

         1.4 Replacement of Warrants. On receipt of evidence reasonably
satisfactory to the Company of the loss, theft, destruction or mutilation of
this Warrant and, in the case of loss, theft or destruction, on delivery of an
indemnity agreement reasonably satisfactory in form and amount to the Company,
and, in the case of mutilation, on surrender and cancellation of this Warrant,
the Company at its expense shall execute and deliver, in lieu of this Warrant, a
new warrant of like tenor.

         1.5 Merger or Consolidation of the Company. Upon the closing of any
Acquisition, the successor entity shall assume the obligations of this Warrant,
and this Warrant shall be exercisable for the same securities, cash, and
property as would be

<PAGE>   2

payable for the Shares issuable upon exercise of the unexercised portion of this
Warrant as if such Shares were outstanding on the record date for the
Acquisition and subsequent closing. The Warrant Price shall be adjusted
accordingly.

                      ARTICLE 2. ADJUSTMENTS TO THE SHARES.

         2.1 Unit Distribution. If the Company distributes Shares pro-rata to
Members for no consideration, then upon exercise of this Warrant, for each Share
acquired, Holder shall receive, without cost to Holder, the total number and
kind of securities to which Holder would have been entitled had Holder owned the
Shares of record as of the date the dividend or subdivision occurred.

         2.2 Reclassification, Exchange or Substitution. Upon any
reclassification, exchange, substitution, or other event that results in a
change of the number and/or class of the securities issuable upon exercise or
conversion of this Warrant, Holder shall be entitled to receive, upon exercise
of this Warrant, the number and kind of securities and property that Holder
would have received for the Shares if this Warrant had been exercised
immediately before such reclassification, exchange, substitution, or other
event. The Company or its successor shall promptly issue to Holder a new Warrant
for such new securities or other property. The new Warrant shall provide for
adjustments which shall be as nearly equivalent as may be practicable to the
adjustments provided for in this Article 2 including, without limitation,
adjustments to the Warrant Price and to the number of securities or property
issuable upon exercise of the new Warrant. The provisions of this section shall
similarly apply to successive reclassifications, exchanges, substitutions, or
other events.

         2.3 Adjustments for Combinations, Etc. If the outstanding Shares are
combined or consolidated, by reclassification or otherwise, into a lesser number
of Shares, the Warrant Price shall be proportionately increased and the number
of Shares acquirable hereunder shall be proportionately decreased.

         2.4 Fractional Shares. No fractional Shares shall be issuable upon
exercise or conversion of the Warrant and the number of Shares to be issued
shall be rounded down to the nearest whole number. If a fractional Share
interest arises upon any exercise of this Warrant, the Company shall eliminate
such fractional Share by paying Holder an amount computed by multiplying the
fractional share by the fair market value of a full Share.

                   ARTICLE 3. REPURCHASE RIGHTS OF THE COMPANY

         3.1 Repurchase Rights of Company. Holder hereby grants to the Company
certain repurchase rights with respect to the Shares (the "Repurchasable
Shares").

         3.2 Right of Repurchase. In the event this Warrant or any portion
hereof is exercised by Holder or any assignee of Holder, following the earlier
of the (i) termination

                                       2

<PAGE>   3

of any Telecommunications Access Agreement by and among BlueStar Communications,
Inc (an affiliate of the Company), Boyle Investment Company and the owners of
certain buildings managed by Boyle Investment Company of even date herewith (the
"Agreements") or (ii) the exclusivity provision set forth in any such Agreement,
the Company shall have the right, but not the obligation, and option to
repurchase all or any portion of the Repurchasable Shares at a purchase price
per share of $5.00 (as may be adjusted pursuant to Article 2 of this Warrant).
Any assignee of Holder shall be bound by the terms of this Section 3.

         3.3 Non-repurchasable Shares. On the last day of each full calendar
month following the execution of this Warrant and the Agreements, provided all
the Agreements and all the exclusivity provision contained therein shall be in
full force and effect, 2.778% of the Repurchasable Shares shall become
"Non-repurchasable Shares."

         3.4 Exercise of Repurchase Rights. The Company may exercise its
repurchase rights under this Section 3 by giving written notice to Holder. The
notice shall specify the number of Repurchasable Shares that the Company
desires to repurchase and setting a date and location for the closing of the
repurchase. This notice shall be given within 90 days following the date of
termination of the Agreement or the exclusivity provision therein. Upon the
giving of notice, Holder shall be obligated to sell to the Company, and the
Company shall be obligated to purchase from the Holder, the number of
Repurchasable Shares specified in the notice.

             ARTICLE 4. REPRESENTATIONS AND COVENANTS OF THE COMPANY

         4.1 Representations and Warranties. The Company hereby represents and
warrants to the Holder that all Shares which may be issued upon the exercise of
the purchase right represented by this Warrant, shall, upon issuance, be duly
authorized, validly issued, fully paid and nonassessable, and free of any liens
and encumbrances except for restrictions on transfer provided for herein or
under applicable federal and state securities laws.

         4.2 Notice of Certain Events. If the Company proposes at any time (a)
to distribute Shares pro-rata to its shareholders; (b) to offer for subscription
pro rata to the holders of any class or series of its stock any additional
Shares of any class or series or other rights; (c) to effect any
reclassification or recapitalization of common stock; or (d) to merge or
consolidate with or into any other corporation, or sell, lease, license, or
convey all or substantially all of its assets, or to liquidate, dissolve or wind
up, then, in connection with each such event, the Company shall give Holder (1)
prompt prior written notice of the date on which a record will be taken for such
dividend, distribution, or subscription rights (and specifying the date on which
the holders of Shares will be entitled thereto) or for determining rights to
vote, if any, in respect of the matters referred to in (c) and (d) above; and
(2 in the case of the matters referred to in (c) and (d) above, prompt prior
written notice of the date when the same will take place (and specifying the

                                       3

<PAGE>   4

date on which the holders of Shares will be entitled to exchange their common
stock for securities or other property deliverable upon the occurrence of such
event).

                     ARTICLE 5. INVESTMENT REPRESENTATIONS.

5.1  Holder represents and warrants to Company that:

     A. The grant of this Warrant and the purchase and sale of Shares upon the
     exercise thereof is intended to be exempt from registration under the
     Securities Act of 1933, as amended ("1933 Act") and from registration under
     the Tennessee Securities Act of 1980, as amended ("1980 Act") by virtue of
     certain exemptions therein provided. Holder also understands that this
     Warrant and the purchase and sale of Shares upon the exercise thereof is
     subject to the restrictions on transferability contained in Rule 144 of the
     1933 Act.

     B. Holder is acquiring this Warrant solely for his own account and for
     investment purposes only, with no view to any resale or distribution of the
     Interest, in whole or in part, in violation of the 1933 Act or the 1980
     Act, and no other person has any direct or indirect beneficial interest in
     such Warrant.

     C. Holder understands the Warrant and the purchase and sale of Shares upon
     the exercise thereof have not been registered under the 1933 Act, the 1980
     Act, or any other securities laws in reliance upon exemptions from the
     registration requirements. Holder understands and agrees that the Warrant
     and the purchase and sale of Shares upon the exercise thereof must be held
     indefinitely unless the sale thereof is subsequently registered under
     applicable securities laws or unless an exemption from such registration is
     available. Holder is also aware that neither the Securities and Exchange
     Commission nor any securities commission of any state nor any other
     regulatory authority has approved or disapproved or passed upon the merits
     of Holder's purchase of the Warrant and the purchase and sale of Shares
     upon the exercise thereof.

     D. Holder is intimately familiar with the operations and financial
     condition of the Company. Holder has been provided with full and complete
     access to all contracts, documents, records, and books pertaining to the
     Company, its organization, corporate existence, business, and operations
     which are or have been deemed material in evaluating Holder's purchase of
     the Shares upon the exercise of the Warrant.

                                       4
<PAGE>   5

     E. Holder has had a reasonable opportunity to ask questions of, and receive
     answers from, responsible persons and officers acting on behalf of the
     Company concerning the business, operations, and prospects of the Company
     and the Warrant and the purchase and sale of Shares upon the exercise
     thereof, and all such questions have been answered to Holder's full
     satisfaction. Holder has received a copy of the Company's business plan and
     understands the risks involved in investing in the Company.

     F. No oral or written representations other than as expressly set forth
     herein have been made to Holder or by or on behalf of the Company or any
     person in connection with Holder's purchase of the Shares upon the exercise
     of the Warrant.

     G. The opportunity to purchase the Shares upon the exercise of the Warrant
     was made to Holder privately and not as a result or as a consequence of any
     advertisement, article, notice, circular, letter, or other communication
     published in any newspaper, magazine, or similar media, or transmitted over
     broadcast or cable television, or radio.

     H. The opportunity to purchase the Shares upon the exercise of the Warrant
     was made available to Holder through direct communication by Seller and not
     through or by way of any intermediary, broker, or dealer in securities.

     I. Holder has adequate means of providing for its current needs and all
     foreseeable personal contingencies, is able to bear the substantial
     economic risks of his purchase of the Shares upon the exercise the Warrant
     for an indefinite period of time, has no need for liquidity in such
     investment, and could afford a complete loss of such investment.

     J. Holder's overall commitment to investments which are not readily
     marketable is not disproportionate to Holder's net worth and Holder's
     overall commitment to such investments which are not liquid will not become
     excessive as a result of this purchase of the Shares upon the exercise of
     the Warrant.

     K. Holder has, or has employed persons with, sufficient knowledge and
     experience in financial, tax, and business matters to enable him to utilize
     the information made available to him in connection with his purchase of
     the Shares upon the exercise of the arrant and to evaluate the merits and
     risks of his purchase and to make an informed decision in that regard.

     L. Holder is not relying on the Company with respect to any tax
     considerations or business or economic forecasts relating to Holder's
     purchase of the Shares upon the exercise of the Warrant.

                                       5
<PAGE>   6

     M. Holder understands that his purchase of the Shares involves a number of
     significant risks of loss and may be considered to be speculative. Holder
     recognizes and understands that there are no assurances that the Company
     will be profitable or otherwise successful at any time in the future.

     N. Holder is an accredited investor as that term is defined in Rule 501 of
     Regulation D promulgated under the Securities Act of 1933, as amended.

     O. The foregoing representations, warranties, and agreements are, and shall
     be and remain, true and correct in all respects on and as of the date
     hereof and as of the actual date the Warrant is are distributed to Holder.

                            ARTICLE 6. MISCELLANEOUS.

                                STOCK RESTRICTION
                          AND SPECIAL PAYMENT AGREEMENT
                                 RICHARD BURTNER

         This Stock Restriction and Special Payment Agreement (this
"Agreement"), dated as of March 17, 1999, is by and between BlueStar Properties,
Inc., a Tennessee corporation (the "Company"), with its principal executive
offices at 131 Second Avenue North, Nashville, Tennessee 37201, and Richard
Burtner (the "Stockholder"), an individual residing at 6337 Johnson Chapel Road,
Brentwood, Tennessee 37027.

         The Company proposes to enter into a Series A Preferred Stock Purchase
Agreement with certain investors, of even date herewith (the "Series A Purchase
Agreement"), pursuant to which such investors will purchase certain securities
from the Company. The execution and delivery of this Agreement by the Company
and the Stockholder is a condition precedent to the transactions contemplated by
the Series A Purchase Agreement, which the Company and the Stockholder believe
will benefit the Company and will also benefit the Stockholder, in his capacity
as a stockholder of the Company.

         Accordingly, to induce the Company and the proposed investors to enter
into and consummate the transactions contemplated by the Series A Purchase
Agreement, the Company and the Stockholder agree as follows:

         1. REPURCHASE RIGHTS OF THE COMPANY. The Stockholder currently holds an
aggregate of 665,766 shares (including any shares issued in respect thereof by
reason of any stock dividend, stock split, recapitalization, or other similar
event affecting such shares occurring after the date hereof) (the "Total
Shares") of the Company's Common Stock, $0.01 par value per share ("Common
Stock"). The Stockholder hereby grants to the Company certain repurchase rights
with respect to 65% of the Total Shares (i.e., 432,747 shares of Common Stock)
(the "Restricted Shares"), as set forth in this Section 1.

         (A) ESCROW. To ensure the availability for delivery of the
Stockholder's Repurchasable Shares (as defined below in Section 1(c) hereof)
upon repurchase by the Company pursuant to the Repurchase Option (as defined
below in Section 1(b) hereof), the Stockholder shall, upon execution of this
Agreement, deliver and deposit with the corporate secretary of the Company as
escrow agent (the "Escrow Holder") the share certificate(s) representing the
Repurchasable Shares, together with a stock assignment duly endorsed in blank,
in the form attached hereto as Exhibit A-1. The Repurchasable Shares and stock
assignment shall be held by the Escrow Holder, pursuant to the Joint Escrow
Instructions of the Company and Stockholder in the form attached hereto as
Exhibit A-2, until such time as the number of Repurchasable Shares is zero. [As
a further condition to the Company's obligations under this Agreement, the
Company may require the spouse of Stockholder, if any, to execute and deliver to
the Company a Consent of Spouse in the form attached hereto as Exhibit A-3.]

<PAGE>   2

             Subject to the terms hereof, the Stockholder shall have all the
rights of a shareholder with respect to the Restricted Shares while they are
held in escrow, including without limitation, the right to vote the Restricted
Shares and to receive any cash dividends declared thereon. If, from time to time
during the period of time in which there are Repurchasable Shares, there is (i)
any stock dividend, stock split, combination of shares or other similar event
affecting the Restricted Shares, or (ii) any merger or sale of all or
substantially all of the assets or other acquisition of the Company, any and all
new, substituted or additional securities to which the Stockholder is entitled
by reason of the Stockholder's ownership of the Restricted Shares shall be
immediately subject to this escrow, deposited with the Escrow Holder and
included thereafter as "Restricted Shares," "Repurchasable Shares" and
"Non-Repurchasable Shares," as the case may be and as applicable, for purposes
of this Agreement and the Repurchase Option.

         (B) RIGHT TO REPURCHASE RESTRICTED SHARES. Following termination of the
Stockholder's employment with the Company, the Company will have the right and
option (the "Repurchase Option"), but not the obligation, to repurchase all or
any portion of the Repurchasable Shares (as defined in Section 1(c) hereof), at
a purchase price per Share equal to $0.147. The Stockholder will not sell,
pledge, or otherwise transfer any Repurchasable Shares or any interest therein,
and all certificates representing Repurchasable Shares will bear appropriate
restrictive legends referring to the restrictions on transfer and repurchase
rights of the Company under this Agreement.

          (C) NON-REPURCHASABLE SHARES. For purposes of this Agreement, and
subject to the following provisions, 2.0833% of the Restricted Shares will
become "Non-Repurchasable Shares" on the last day of each calendar month
beginning with April 1999, provided, in each case, that as of the relevant date
the Stockholder remains employed by the Company. All Restricted Shares that are
not Non-Repurchasable Shares as of any particular time of reference are referred
to in this Agreement as "Repurchasable Shares."

In addition to the foregoing: (1) in the event of a Business Combination, as
defined below, the greater of (a) 50% of the then remaining Repurchasable
Shares or (b) 25% of the Restricted Shares, will automatically and without
further action become Non-Repurchasable Shares; and (2) in addition to the
provision of the foregoing clause (1), in the event of an involuntary
termination of the Stockholder's employment with the Company for any reason or
no reason other than for Cause (as defined below), then 108,187 Shares of the
Restricted Shares will automatically and without further action become
Non-Repurchasable Shares.

         For purposes of this Section 1, "Business Combination" shall mean (i)
the sale, lease or exchange (for cash, shares of stock, securities or other
consideration) of all or substantially all the property and assets of the
Company or (ii) the merger or consolidation of the Company into or with any
other corporation or entity or the merger or consolidation of any other
corporation into or with the Company (except for a merger or consolidation in
which the holders of the voting capital stock of

<PAGE>   3

the Company hold more than 50% of the voting rights of the surviving entity).
For purposes of this Section 1 and Section 2 below, an involuntary termination
of employment shall include a reduction in the authorities, duties or
responsibilities of the Stockholder to a level significantly below his then
existing authorities, duties or responsibilities. A termination shall be for
"Cause" if the Board of Directors of the Company shall determine in good faith
that any one or more of the following has occurred: (i) the Stockholder shall
have committed a material act of theft, dishonesty, gross dereliction of duty,
fraud, embezzlement, misappropriation, or material breach of fiduciary duty
against the Company, or has committed any other act of grave misconduct against
the Company, or (ii) the Stockholder shall have been convicted by a court of
competent jurisdiction of, or pleaded guilty or nolo contendere to, any felony
or any crime involving moral turpitude or dishonesty.

         (D) EXERCISE OF REPURCHASE RIGHTS. The Company may exercise its
repurchase rights under this Section 1 by giving written notice (a "Repurchase
Notice") to the Stockholder and the Escrow Holder, specifying the number of
Repurchasable Shares that the Company desires to repurchase and setting a date
(not later than 30 days after the date of such Repurchase Notice) for the
closing of such repurchase. A Repurchase Notice may be given at any time within
90 days following the date of termination of the Stockholder's employment
hereunder, whereupon, if such time period for giving such Repurchase Notice
shall lapse without the Company having given such Repurchase Notice, the
Repurchase Option shall automatically expire.

         Upon the giving of a Repurchase Notice, the Stockholder will be
obligated to sell to the Company, and the Company will be obligated to purchase,
the number of Repurchasable Shares specified in the Repurchase Notice, with the
closing of the purchase and sale to take place at the principal office of the
Company or its counsel on the date specified in the Repurchase Notice. At the
closing, the Escrow Holder will deliver to the Company the certificates
representing the Repurchasable Shares to be repurchased, together with duly
executed stock powers sufficient effectively to transfer ownership of such
Repurchasable Shares to the Company, free and clear of all liens, security
interests, and other encumbrances, and the Company will pay for such
Repurchasable Shares by check or wire transfer (and will issue to the
Stockholder a new stock certificate representing any Restricted Shares
represented by the certificate delivered to the Company that are not repurchased
by the Company). In the event that the Company fails to give a Repurchase Notice
or if the Repurchase Option expires unexercised, all of the then Repurchasable
Shares shall automatically and without further action become Non-Repurchasable
Shares.

         2. SPECIAL PAYMENT/EFFECT OF TERMINATION. In the event that at any time
the Stockholder's employment with the Company is terminated for any reason or no
reason other than for Cause, the Company shall pay to the Stockholder (a) within
fourteen (14) days after the effective date of such termination, a cash payment

         3. "LOCK-UP" AGREEMENT. The Stockholder agrees that if the Company at
any time or from time to time deems it necessary or desirable to make any
registered public offering(s) of shares of Common Stock, then upon the Company's
request, the Stockholder will not sell, make any short sale of, loan, grant any
option for the purchase of, pledge, or otherwise encumber or otherwise dispose
of any of the Restricted Shares during such period (not to exceed 180 days)
commencing on the effective date of the registration statement relating to any
such offering as the Company may request, except with the prior written consent
of the Company. The Stockholder agrees that he will enter into an agreement with
the Company's underwriters for a registered public offering if requested by such
underwriter, with respect to the foregoing agreements in this Section 3 and on
customary terms and conditions.

         4. NO ASSIGNMENTS; BENEFITS OF AGREEMENT. Neither party will assign any
rights or delegate any obligations hereunder without the consent of the other
party (except that the Company may assign its rights and delegate its
obligations hereunder to any successor to its business, whether by merger or
consolidation, sale of stock or of all or substantially all of assets, or
otherwise), and any attempt to do so will be void. This Agreement will bind and
inure to the benefit of the parties hereto and their respective heirs,
successors, and permitted assigns.

         5. NO THIRD-PARTY BENEFICIARIES. Nothing in this Agreement is intended
to or will confer any rights or remedies on any Person other than the parties
hereto, their respective heirs, successors, and permitted assigns.

         6. NOTICES. All notices, requests, payments, instructions, or other
documents to be given hereunder will be in writing or by written
telecommunication, and will be deemed to have been duly given if (i) delivered
personally (effective upon delivery), (ii) mailed by registered or certified
mail, return receipt requested, postage prepaid (effective three business days
after dispatch), (iii) sent by a reputable, established courier service that
guarantees next business day delivery (effective the next business day), or (iv)

foregoing methods (effective upon receipt of the telecopy in complete, readable
form), addressed to the recipient party at his or its address set forth in the
first paragraph hereof (or to such other address as the recipient party may have
furnished to the sending party for the purpose pursuant to this section).

         7. COUNTERPARTS. This Agreement may be executed by the parties in
separate counterparts, each of which when so executed and delivered will be an
original, but all of which together will constitute one and the same agreement.
In pleading or proving this Agreement, it will not be necessary to produce or
account for more than one such counterpart.

chosen by the parties to express their mutual intent, and no rule of strict
construction will be applied against either party.

         10. WAIVERS; AMENDMENTS. No waiver of any breach or default hereunder
will be valid unless in a writing signed by the waiving party. No failure or
other delay by any party exercising any right, power, or privilege hereunder
will be or operate as a waiver thereof, nor will any single or partial exercise
thereof preclude any other or further exercise thereof or the exercise of any
other right, power, or privilege. This Agreement may be amended only with the
prior written consent of the parties hereto.

         11. ENTIRE AGREEMENT. This Agreement contains the entire understanding
and agreement between the parties, and supersedes any and all prior and/or
contemporaneous understandings or agreements between them, with respect to the
subject matter hereof.

         12. EQUITABLE RELIEF. The Stockholder acknowledges that any breach by
him of his obligations under this Agreement would cause substantial and
irreparable damage to the Company, and that money damages would be an inadequate
remedy therefor. Accordingly, the Stockholder agrees that the Company will be
entitled to an injunction, specific performance, and/or other equitable relief
to prevent the breach of such obligations.

         13. GOVERNING LAW. This Agreement will be governed by and interpreted
and construed in accordance with the internal laws of the State of Tennessee

Corporate Secretary
BlueStar Properties, Inc.

Nashville, TN 37201

Dear Sir/Madam:

         As Escrow Agent for both BlueStar Properties, Inc., a Tennessee
corporation (the "Company"), and the undersigned stockholder of the Company (the
"Stockholder"), you are hereby authorized and directed to hold the documents
delivered to you pursuant to Section 1(a) of that certain Stock Restriction and
Special Payment Agreement ("Agreement") between the Company and the undersigned,
dated as of March ____, 1999, in accordance with the following instructions:

         1. In the event the Company exercises the Company's Repurchase Option
set forth in the Agreement, the Company and the Stockholder shall give to you a
written notice from both of them specifying the number of Repurchasable Shares
to be purchased, the purchase price, and the time for a closing hereunder at the
principal office of the Company (the "Joint Written Instructions"). Stockholder
and the Company hereby irrevocably authorize and direct you to close the
transaction contemplated by such notice in accordance with the terms of said
notice.

         2. At the closing, you are directed (a) to date the stock assignments
necessary for the transfer in question, (b) to fill in the number of shares
being transferred, and (c) to deliver same, together with the certificate
evidencing the shares of stock to be transferred, to the Company, against the
simultaneous delivery to you of the purchase price (by cash, a check, or some
combination thereof) for the number of shares of stock being purchased, each of
the foregoing pursuant to the Joint Written Instructions.

         3. Stockholder irrevocably authorizes the Company to deposit with you
any certificates evidencing Repurchasable Shares to be held by you hereunder
and any additions, substitutions and/or subtractions to said Repurchasable
Shares as defined in the Agreement. Stockholder does hereby irrevocably
constitute and appoint you as Stockholder's attorney-in-fact and agent for the
term of this escrow to execute with respect to such securities all documents
necessary or appropriate to make such securities negotiable and to complete any
transaction herein contemplated, including but

required applications for consent to, or notice of transfer of, the securities.
Subject to the provisions of this paragraph 3, Stockholder shall exercise all
rights and privileges of a shareholder of the Company while the stock is held by
you.

         4. Upon written request of the Stockholder, but no more than twice per

shall deliver to Stockholder a certificate or certificates representing so many
of the Restricted Shares as are not then subject to the Company's Repurchase
Option. Simultaneously with the closing of a Business Combination, or within
ninety (90) days after Stockholder ceases to be an employee of the Company (and
consistent with the provisions pertaining to the termination of employment of
the Stockholder as more fully set forth in the Agreement), you shall deliver to
Stockholder a certificate or certificates representing the aggregate number of
Non-Repurchasable Shares held by you and all Repurchasable Shares not
purchased by the Company under its Repurchase Option.

         5. If at the time of termination of this escrow you should have in your
possession any documents, securities, or other property belonging to
Stockholder, you shall deliver all of the same to Stockholder and shall be
discharged of all further obligations hereunder.

         6. Your duties hereunder may be altered, amended, modified or revoked
only by a writing signed by all of the parties hereto.

are specifically set forth herein and may rely and shall be protected in relying
or refraining from acting on any instrument reasonably believed by you to be
genuine and to have been signed or presented by the proper party or parties. You
shall not be personally liable for any act you may do or omit to do hereunder as
Escrow Agent or as attorney-in-fact for Stockholder while acting in good faith,
and any act done or omitted by you pursuant to the advice of your own attorneys
shall be conclusive evidence of such good faith.

         8. You are hereby expressly authorized to disregard any and all
warnings given by any of the parties hereto or by any other person or
corporation, excepting only orders or process of courts of law, and are hereby
expressly authorized to comply with and obey orders, judgments or decrees of any
court. In case you obey or comply with any such order, judgment or decree, you
shall not be liable to any of the parties hereto or to any other person, firm or
corporation by reason of such compliance, notwithstanding any such order,
judgment or decree being subsequently reversed, modified, annulled, set aside,
vacated or found to have been entered without jurisdiction.

         9. You shall not be liable in any respect on account of the identity,
authorities or rights of the parties executing or delivering or purporting to
execute or deliver the Agreement or any documents or papers deposited or called
for hereunder.

experts as you may deem necessary properly to advise you in connection with your
obligations hereunder, may rely upon the advice of such counsel, and may pay
such counsel reasonable compensation therefor to be reimbursed by the Company.

         12. Your responsibilities as Escrow Agent hereunder shall terminate if
you shall cease to be an officer or agent of the Company or if you shall resign
by written notice to each party. In the event of any such termination, the
Company shall appoint a successor Escrow Agent.

         13. If you reasonably require other or further instruments in
connection with these Joint Escrow Instructions or obligations in respect
hereto, the necessary parties hereto shall join in furnishing such instruments.

         14. It is understood and agreed that should any dispute arise with
respect to the delivery and/or ownership or right of possession of the
securities held by you hereunder, you are authorized and directed to retain in
your possession without liability to anyone all or any part of said securities
until such disputes shall have been settled either by mutual written agreement
of the parties concerned or by a final order, decree or judgment of a court of
competent jurisdiction after the time for appeal has expired and no appeal has
been perfected, but you shall be under no duty whatsoever to institute or defend
any such proceedings.

         15. Any notice required or permitted hereunder shall be given in
writing and shall be deemed effectively given upon personal delivery or upon
deposit in the United States Post Office, by registered or certified mail with
postage and fees prepaid, addressed to each of the other parties thereunto
entitled at the following addresses or at such other addresses as a party may
