                               STOCK RESTRICTION
                         AND SPECIAL PAYMENT AGREEMENT
                                 SCOTT KOZICKI

     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 Scott Kozicki (the
"Stockholder"), and individual residing at 409 Pebble Creek Circle, Antioch,
Tennessee 37013.

     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 1,628,604 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., 1,058,592 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 Repurchaseable 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
Repurchaseable Shares, together with a stock assignment duly endorsed in blank,
in the form attached hereto as Exhibit A-1. The Repurchaseable 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 Repurchaseable Shares is zero. [As
a further condition to the Company's obligations under this Agreement, the
Company may require the spouse of Stockholder,
<PAGE>   2
if any, to execute and deliver to the Company a Consent of Spouse in the form
attached hereto as Exhibit A-3.]

          Subject to the terms hereof, the Stockbroker 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 Repurchaseable 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," "Repurchaseable Shares" and
"Non-Repurchaseable 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 Repurchaseable 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 Repurchaseable Shares or any interest therein,
and all certificates representing Repurchaseable Shares will bear appropriate
restrictive legends referring to the restrictions on transfer and repurchase
rights of the Company under this Agreement.

     (c)  NON-REPURCHASEABLE SHARES. For purposes of this Agreement, and subject
to the following provisions, 2.0833% of the Restricted Shares will become
"Non-Repurchaseable 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-Repurchaseable Shares as of any particular time of reference are referred to
in this Agreement as "Repurchaseable Shares."

In addition to the foregoing: (1) in the even of a Business Combination, as
defined below, the greater of (a) 50% of the then remaining Repurchaseable
Shares or (b) 25% of the Restricted Shares, will automatically and without
further action become Non-Repurchaseable 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 264,649 Shares of the
Restricted Shares will automatically and without further action become
Non-Repurchaseable 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
<PAGE>   3
of 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 equal to six months' of such Stockholder's then base salary, plus (b)
such Stockholder's pro rata portion (based upon the number of days actually
worked by such Stockholder) of any bonus pursuant to any such then existing
bonus plan or arrangements.
<PAGE>   4
     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) sent by telecopier followed within 24 hours by confirmation by one of the
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.

     8.   CAPTIONS.  The captions of sections or subsections of this Agreement
are for reference only and will not affect the interpretation or construction
of this Agreement.

<PAGE>   5
     9.   CONSTRUCTION.  The language used in this Agreement is the language
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
(without reference to principles of conflicts or choice of law).

     14.  LEGENDS.  The share certificate evidencing the Restricted Shares, if
any, shall be endorsed with the following legend (in addition to any legend
required under applicable state securities laws):

     THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN
RESTRICTIONS UPON TRANSFER AND RIGHTS OF REPURCHASE AS SET FORTH IN A STOCK
RESTRICTION AND SPECIAL PAYMENT AGREEMENT BETWEEN THE COMPANY AND THE
SHAREHOLDER, DATED AS OF MARCH 17, 1999, A COPY OF WHICH IS ON FILE WITH THE
SECRETARY OF THE COMPANY AND WILL BE PROVIDED UPON WRITTEN REQUEST.

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 Repurchaseable 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 Repurchaseable Shares to be held by you hereunder and
any additions, substitutions and/or subtractions to said Repurchaseable 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 not limited to the filing with any applicable
state blue sky authority of any required applications for consent to, or notice
of transfer of, the securities. Subject to the provisions of this paragraph 3,
<PAGE>   9

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
calendar year, unless the Company's Repurchase Option has been exercised, you
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-Repurchaseable Shares held by you and all Repurchaseable 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.

     7.   You shall be obligated only for the performance of such duties as 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.

    10.   You shall not be liable for the outlawing of any rights under the
statute of limitations with respect to these Joint Escrow Instructions or any
documents deposited with you.
<PAGE>   10
     11.  You shall be entitled to employ such legal counsel and other 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 designate by ten
days' advance written notice to each of the other parties hereto.
