          (d) REGISTRATION. The TRC Shares deliverable hereunder will not be
registered and will bear a restrictive legend in substantially the following
form:

               "The Stock represented by this Certificate has not been
               registered under the Federal Securities Act of 1933, as amended,
               and may not be assigned, transferred or otherwise disposed of
               without an opinion of counsel satisfactory to the Company that an
               exemption under such Act is available therefor or that an
               applicable registration statement under such Act is effective
               with respect thereto. In addition, the stock has not been
               registered or qualified in accordance with the securities laws of
               any state and transfer may be made only in compliance with such
               laws."

          (e) Registration Rights. If, within one (1) year after the Closing
Date, Parent files a registration statement under the Securities Act of 1933, as
amended, or any successor statute then in effect, covering a public offering in
excess of $7,500,000 by Parent or any stockholder of Parent of shares of the
common stock of Parent other than a registration statement solely in connection
with an employee benefit plan, Buyer shall first so notify Seller of Parent's
intent to file a registration statement. Within sixty (60) days after giving
such notice to Seller, Seller may, by written notice to Parent, request that
Seller's shares be included in such registration statement. In such case and
with the giving of Seller's notice, Buyer shall use its best efforts to include
such shares in the registration statement and related underwriting arrangements.
No such effort need be made, however, if, in the reasonable opinion of counsel
for Parent, the disposition of such shares is exempt from applicable
registration requirements at that time. If the offering by Parent is
underwritten, any shares disposed of pursuant to this provision will be
underwritten by the same underwriter or underwriters on the same basis as other
shares included in the offering. In the event the managing underwriter or
underwriters refuse to include all of the shares offered for disposition
hereunder, Parent may reasonably limit the number of shares which may be offered
by Seller hereunder. Seller shall cooperate with Parent in the preparation and
filing of any registration statement, and shall make the customary agreements,
representations, warranties and indemnifications to the underwriter(s) with
respect to any shares included in an underwriting hereunder.

indemnify and hold harmless Seller from and against any and all Losses (as
defined in Section 10.2) incurred or suffered by Seller arising out of,
resulting from, or relating to (a) any breach of any of the representations or
warranties made by Buyer in this Agreement; (b) any failure by Buyer to perform
any of its covenants or agreements contained in this Agreement; or (c) the
business or operations of Company after the Closing, except to the extent
arising out of, resulting from or relating to any breach of any of the
representations and warranties and covenants of Seller under this Agreement or
the business or operations of Company prior to the Closing.

     10.4 PROCEDURE. (a) In the event that any party hereto shall sustain or
incur any Losses in respect of which indemnification may be sought by such party
pursuant to this Article 10, the party seeking such indemnification (the
"Indemnitee") shall assert a claim for indemnification by giving written notice
thereof (the "Notice") to the party (or parties) providing indemnification (the
"Indemnitor") within thirty (30) days after (i) receipt of written notice of
commencement of any third party litigation against such Indemnitee, (ii) receipt
by such Indemnitee of written notice of any third party claim pursuant to an
invoice, notice of claim or assessment against such Indemnitee, or (iii) such
Indemnitee becomes aware of the existence of any other event in respect of which
indemnification may be sought from the Indemnitor (including, without
limitation, any inaccuracy of any representation or warranty or breach of any
covenant). The Notice shall describe the claim and the specific facts and
circumstances in reasonable detail, and shall indicate the amount, if known, or
an estimate, if possible, of the Losses that have been or may be incurred or
suffered by such Indemnitee. The failure to timely deliver a Notice shall not
relieve the Indemnitor from the obligation to indemnify hereunder except to the
extent that the Indemnitor is prejudiced thereby. In case any third party claim,
action or proceeding (a "Claim") is brought against any Indemnitee, the
Indemnitor shall be entitled to assume the defense thereof, by written notice to
the Indemnitee of its intention to do so within 30 days after receipt of the
Notice. If the Indemnitor shall assume the defense of such Claim, without the
consent of the Indemnitee, which shall not be unreasonably withheld, the
Indemnitor shall not settle such Claim unless such settlement includes as an
unconditional term thereof the giving by the claimant or the plaintiff of a
release of the Indemnitee, satisfactory to the Indemnitee, from all liability
with respect to such Claim. Notwithstanding the assumption by the Indemnitor of
the defense of any Claim as provided in this subsection, the Indemnitee shall be
permitted to join in the defense of such Claim and to employ counsel at its own
expense; PROVIDED, HOWEVER, that if the defendants in any action shall include
both an Indemnitor and any Indemnitee, and such Indemnitee shall have reasonably
concluded that counsel selected by the Indemnitor has a conflict of interest
because of the availability of different or additional defenses to such
Indemnitee, such Indemnitee shall have the right to select separate counsel to
participate in the defense of such action on its behalf, at the expense of the
Indemnitor.

          (b) If the Indemnitor shall fail to notify the Indemnitee of its
desire to assume the defense of any such Claim within the prescribed period of
time, or shall notify the Indemnitee that it will not assume the defense of any
such Claim, then the Indemnitee may assume the defense of any such Claim, in
which event it may do so in such manner as it may deem appropriate, and the
Indemnitor shall be bound by any determinations made in

                                       15

<Page>

any litigation with respect to any Claim or any settlement thereof, provided
that any such determinations or settlement shall not affect the right of the
Indemnitor to dispute any claim for indemnification by the Indemnitee.

          (c) Amounts payable by the Indemnitor to the Indemnitee in respect of
any Losses for which such party is entitled to indemnification hereunder shall
be payable by the Indemnitor as incurred by the Indemnitee. In the event Seller
is obligated to pay Buyer pursuant to this Article 10, Seller may make such
payment by reducing the face amount of the Note by a corresponding amount.

     10.5 INVESTIGATIONS; WAIVERS. The survival periods and rights to
indemnification provided for in this Article shall remain in effect for the
period set forth in Section 10.1 above notwithstanding any investigation at any
time by or on behalf of any party hereto or any waiver by any party hereto of
any condition to such party's obligations to consummate the transactions
contemplated hereby.


11.      TERMINATION

     11.1 TERMINATION AND ABANDONMENT. This Agreement may be terminated and the
transactions contemplated by this Agreement may be abandoned at any time prior
to the Closing;

          (a) by mutual written consent of Buyer and Seller; or

          (b) by Buyer if the Buyer is not reasonably satisfied with the results
of its continuing due diligence regarding the Company; or

          (c) by Buyer, on the one hand, or Seller on the other hand, if the
Closing shall not have occurred on or before December 29, 2000; PROVIDED,
HOWEVER, that the right to terminate this Agreement under this Section 11.1(c)
shall not be available to any party whose failure to fulfill any obligations
under this Agreement had been the cause of, or resulted in, the failure of the
Closing to occur on or before such date; or

          (d) by Buyer, on the one hand, or Seller on the other hand, if any
court of competent jurisdiction shall have issued an order, decree or ruling or
taken any other action restraining, enjoining or otherwise prohibiting the
transactions contemplated under this Agreement and such order, decree, ruling or
other action shall have become final and nonappealable.

     11.2 EFFECT OF TERMINATION. In the event of the termination of this
Agreement pursuant to Section 11.1, this Agreement shall forthwith become void,
and (except as provided in Section 11.3) there shall be no liability or
obligation on the part of any party hereto.

     11.3 FEES AND EXPENSES. Whether or not the transactions contemplated by
this Agreement are consummated, each of the parties hereto shall pay its own
expenses incurred in connection with the transactions contemplated hereby,
including taxes and legal, accounting and other fees. Notwithstanding the
provisions of Section 11.2, if this Agreement is terminated by Seller, on the
one hand, or Buyer, on the other hand, by reason of a breach by the other of
this Agreement, in addition to any other remedy available at law or in equity,
the terminating party shall be reimbursed by the breaching party for all
reasonable out-of-pocket costs and expenses incurred by the terminating party in
connection with the transactions contemplated by this Agreement.


12.      MISCELLANEOUS

     12.1 SPECIFIC PERFORMANCE. Seller, on the one hand, and Buyer, on the other
hand, acknowledge that the other will be irreparably harmed and will have no
adequate remedy at law if such party fails to perform any of its obligations
under this Agreement. It is accordingly agreed that, in addition to any other
remedies which may be available, the Parties shall have the right to obtain
injunctive relief to restrain a breach or threatened breach of, or otherwise
obtain specific performance of, covenants and other agreements of the other
party contained in this Agreement.

     12.2 WAIVERS. No action taken pursuant to this Agreement, including any
investigation by or on behalf of any party hereto, shall be deemed to constitute
a waiver by the party taking such action of compliance with any representation,
warranty, covenant or agreement contained herein. The waiver by any party hereto
of any condition or of a breach of any provision of this Agreement shall not
operate or be construed as a waiver of any other condition or other breach. The
waiver by any party of any of the conditions precedent to its obligations under
this Agreement shall not preclude it from seeking redress for breach of this
Agreement other than with respect to the condition so waived.
