identity of such Third Party and (ii) require each Preferred Holder to sell up
to a number of Securities equal to (x) a fraction (expressed as a percentage)
equal to (A) the total number of Common Shares proposed to be Transferred by
TCR Holding to such Third Party divided by (B) the total number of Common

                  (a) Representation. The bylaws of the Company shall provide

members, TCR Holding shall be entitled to designate four (4) members (the "TCR
Holding Designees") and, subject to the following provisions, the Majority
Preferred Holders shall be entitled to designate one (1) member (the "Fifth
Designee"). Initially, Jefferies shall be entitled, exclusively and in its sole
discretion, to designate the Fifth Designee on behalf of the Majority Preferred
Holders until such time as Jefferies (x) refuses or fails to designate the Fifth
Designee upon the written request of the Majority Preferred Holders and such
board seat remains vacant for 5 days or (y) the Fifth Designee fails to attend
three consecutive meetings of the Board after due notice in each instance. After
the Repurchase Date, TARC shall be entitled, exclusively and in its sole
discretion, to designate the Fifth Designee; provided, that if there shall not
have occurred prior to the first anniversary of the Repurchase Date either an
Initial Public Offering or a sale of all or substantially all of the assets of
either TCR Holding or the Company, then the TCW Funds shall be entitled,
exclusively and in their sole discretion, to designate the Fifth Director.
Notwithstanding the foregoing, however, so long as a Preferred Stock Trigger
Event has occurred and is continuing, the Majority Preferred Holders shall be
entitled, exclusively and in their sole discretion, to appoint three (3) of the
five (5) members of the Board and the TCW Funds and TARC each shall be entitled,
exclusively and in their sole discretion, to designate one (1) member. At any
time that the Majority Preferred Holders are entitled to appoint a majority of
the members of the Board, no meeting of the Board shall take place (or if any
meeting takes place, no action taken at such meeting shall be valid) until the
earlier to occur of (i) 30 days after notice shall have been given to or by the
holders of the Preferred Shares that a Preferred Stock Trigger Event shall have
occurred or (ii) the Majority Preferred Shares shall have duly appointed such
members. Any Person entitled to designate a member of the Board pursuant to the
foregoing provisions also shall be entitled, exclusively and in such Person's
sole discretion, to designate such member for removal from the Board. So long as
no Preferred Stock Trigger Event relating to a breach of Section 4(a) of this
Agreement or Section 4(c) of the TCR Holding Stockholders Agreement has occurred
and is continuing, TCR Holding shall select which Board member shall serve as
Chairman of the Board and Vice Chairman of the Board; otherwise the Majority
Preferred Holders shall make such selection.

                  (b) Major Decisions. Subject to clause (c) below, no action
shall be taken, sum expended, decision made or obligation incurred by or on
behalf of the Company with respect to any matter unless approved or ratified by
a majority of the Board. Notwithstanding the foregoing, unless and until
the Board revokes such authority, Glenn McGinnis shall have general authority to
take actions in the ordinary course of business for and on behalf of the
Company, and Mr. McGinnis also may delegate authority to take such actions to
other employees of the Company over which he has supervisory authority;
provided, that, except to the extent set forth on Exhibit A, no such action
shall be taken if such action would constitute a Major Decision. "Major
Decisions" shall mean and consist of the following:

to any compensation for their service on such Board (other than reimbursement
of reasonable out-of-pocket expenses incurred in connection with Board meetings
or director-related activities for services as a Board member) without the
written consent of Majority Preferred Holders; provided, however, that no

reimburse such Majority Preferred Holders or their Affiliates 

                  (f) Voting Agreement. All parties to this Agreement agree
that this Section 4 shall constitute a voting agreement within the meaning of
Section 218 of the Delaware General Corporation Law.

                  SECTION 5. CERTIFICATES.

                  (a) Restrictive Endorsements. Each certificate evidencing any
Securities shall bear a legend in substantially the following form:

                  "The securities evidenced by this certificate are
                  subject to a Stockholders Agreement dated as of
                  December __, 1998, copies of which are on file at
                  the principal office of the corporation and will be
                  furnished to the holder on request to the Secretary
                  of the corporation. Such Stockholders Agreement
                  provides, among other things, for certain
                  restrictions on voting, sale, transfer, pledge,
                  hypothecation or other disposition of the securities
                  evidenced by this certificate and that such
                  securities may be subject to purchase upon the
                  occurrence of certain events."

                                       9

   10


In addition, unless counsel to the Company has advised that such legend is no
longer needed, each certificate evidencing the Securities shall bear a legend
in substantially the following form:

                  "The securities evidenced by this certificate have
                  not been registered pursuant to the Securities Act
                  of 1933, as amended (the "Act"), or any state
                  securities law, and such securities may not be sold,
                  transferred or otherwise disposed of unless the same
                  are registered and qualified in accordance with the
                  Act and any applicable state securities laws, or in
                  the opinion of counsel reasonably satisfactory to
                  the corporation such registration and qualification
                  are not required."

                  (b) Replacement Certificates. Upon receipt by the Company of
evidence reasonably satisfactory to it of the loss, theft, destruction or
mutilation of any of its respective certificates evidencing any Securities, and
(in the case of loss, theft or destruction) of indemnity reasonably
satisfactory to it, upon surrender and cancellation of such certificate or
receipt of such indemnity, the Company will execute, register and deliver a new
certificate of like tenor in lieu of such lost, stolen, destroyed or mutilated
certificate.

                  SECTION 6. EQUITABLE RELIEF. The parties hereto agree and
declare that legal remedies may be inadequate to enforce the provisions of this
Agreement and that equitable relief, including specific performance and
injunctive relief, may be used to enforce such provisions.

                  SECTION 7. MISCELLANEOUS.

                  (b) Amendment. This Agreement may be changed, modified or
amended by a writing signed by TCR Holding and the Majority Preferred Holders;
provided that no such change, modification or amendment shall be enforceable
against any party to this Agreement whose rights or obligations hereunder will

and signed by such party.

                  (c) Waiver. No failure or delay on the part of the parties or
any of them in exercising any right, power or privilege hereunder, nor any
course of dealing between the parties or any of them shall operate as a waiver
of any such right, power or privilege nor shall any single or partial exercise
of any such right, power or privilege preclude the simultaneous or later
exercise of any other right, power or privilege. The rights and remedies herein
expressly provided are cumulative and are not exclusive of any rights or
remedies which the parties or any of them would otherwise have. No notice to or
demand on the Company shall entitle the Company to any other or further notice
or demand in similar or other circumstances or constitute a waiver of the
rights of the other parties or any of them to take any other or further action
in any circumstances without notice or demand.

                  (d) Counterparts. This Agreement may be executed in two or
more counterparts, each of which shall be deemed to be an original but all of
which together shall constitute one and the same instrument.

                  (e) Governing Law. This Agreement shall be construed in
accordance with and governed by the internal laws of the State of Delaware
applied to contracts to be made and to be performed therein without giving
effect to the considerations of conflicts of laws.

                  (f) Filing. A copy of this Agreement and of all amendments
hereto shall be filed at the principal office of the Company.

                  (g) Termination. This Agreement may be terminated at any time
by an instrument in writing signed by TCR Holding and the Majority Preferred
Holders.

                  (h) All Securities Subject to this Agreement.

                      (i) Any Securities now or hereafter held by any Person
                  shall be held by such Person subject to the transfer and
                  other restrictions of this Agreement and such Person shall be
                  deemed to be a "Holder" for all such purposes of this
                  Agreement; 

                      (ii) A Holder who ceases to own any Securities as
                  provided for in this Agreement shall cease to be a Holder for
                  purposes of this Agreement; and 

                      (iii) The provisions of this Agreement shall be deemed to
                  apply equally to any Security or other equity securities
                  distributed in respect of the Securities.

                  (i) Benefit and Binding Effect. Except as otherwise provided
in this Agreement, no right under this Agreement shall be assignable and any
attempted assignment in violation of this provision shall be void; provided,
that the Preferred Holders may assign their respective rights under this
Agreement to any Person who (i) is, immediately following such assignment, in
compliance with all of the covenants and agreements applicable to the Preferred
Holders hereunder and (ii) assumes all applicable obligations of the Preferred
Holders under this Agreement. Subject to compliance with the terms of this
Agreement regarding Transfer of Securities, this Agreement shall be binding
upon and inure to the benefit of the parties and their executors,
administrators, personal representatives, heirs, successors and permitted
assigns. Except as set forth in this clause (i), this Agreement does not create
and shall not be construed as creating any rights enforceable by any Person not
a party hereto.

                  (j) Severability. In the event that any one or more of the
provisions contained herein, or the application thereof in any circumstance, is
held invalid, illegal or unenforceable, the validity, legality and
enforceability of any such provisions in every other respect and of the
remaining provisions contained herein shall not be affected or impaired
thereby.


                  (k) Further Assurances. Each Holder shall cause all Securities
that are entitled to vote and are registered in the name of such Holder to be
voted, and will otherwise take or cause to be taken all such other action as may
be necessary, to implement the provisions of this Agreement and shall not take
any action inconsistent herewith or therewith.
