and soliciting proxies and

                                       2.

voting such proxies in favor of the election of such person to the Board);
provided that such designee is reasonably acceptable to the Company.

                  (c) OBSERVER RIGHTS. The Company shall, for so long as the
Carlyle Entities and their Affiliates collectively own or control at least 10%

Series D Senior Convertible Participating Preferred Stock and Series E Senior
Cumulative Convertible Participating Preferred Stock into the Company's Common
Stock), permit an individual designated by the Carlyle Entities and acceptable
to the Company to attend and observe meetings of the Board, and such designee
shall have the right to receive all written information provided by the Company
to the Board (but only if specifically requested by such designee). Such
designee shall have no right to vote on any matter presented to the Board, but
otherwise shall have all rights of a director, including: (i) the right to
examine books and records of the Company; (ii) the right to review and
participate in all discussions of the Board including, without limitation,

term of this Agreement, without the Company's prior written consent, no Carlyle
Entity and no investment partnership in which Carlyle or one of its wholly owned
subsidiaries is a general partner will, in any manner, directly or indirectly:

                  (a) acquire, publicly announce an intention to acquire,
publicly offer or propose to acquire, or agree to acquire, directly or
indirectly, by purchase or otherwise, beneficial ownership of any Voting
Securities, or direct or indirect rights or options to acquire (through
purchase, exchange, conversion or otherwise) any Voting Securities if as a
result of such acquisition, the Carlyle Entities and their Affiliates would
beneficially own or have the right to acquire Voting Securities representing
more than 30% of the issued and outstanding Voting Securities; provided,
however, that this Section 3(a) shall not restrict any Carlyle Entity from
acquiring the Voting Securities initially issuable to the Carlyle Entities under
the terms of the Merger Agreement or issuable pursuant to the conversion rights
under the Certificate of Designations for the Series D Senior Convertible
Participating Preferred Stock or the Certificate of Designations for the Series
E Senior Cumulative Convertible Participating Preferred Stock;

                  (b) seek representation on the Board of the Company (other
than pursuant to the terms of Section 2 hereof or pursuant to the Certificate of
Designations for the Series E Senior Cumulative Convertible Participating
Preferred Stock);


                                       3.

                  (c) make any public announcement or proposal whatsoever with
respect to a merger or other business combination, sale or transfer of
substantially all of the assets, recapitalization, dividend, share repurchase,
liquidation or other extraordinary corporate transaction with the Company or any
other transaction which would result in a change of control of the Company
(other than the sale of securities or capital stock of the Company by the
Carlyle Entities or their Affiliates), advise, assist, solicit or encourage any
other persons to make any such statement or proposal;

                  (d) make, directly or indirectly, any "solicitation" of
"proxies" (as such terms are defined in Rule 14a-1 under the Securities Exchange
Act of 1934, so amended (the "1934 ACT")) to vote any Voting Securities, seek to
advise, encourage or influence any person or entity with respect to the voting
of any Voting Securities, initiate or propose any stockholder proposal or induce
or attempt to induce any other person to initiate any stockholder proposal
(other than any such action in furtherance of the election to the Board of the
person designated by the Carlyle Entities pursuant to Section 2);

                  (e) deposit any Voting Securities into a voting trust, unless
the trustee of such voting trust agrees to be bound by the terms of this
Agreement;

                  (f) form, join or in any way participate in a "group" (within
the meaning of Section 13(d)(3) of the 1934 Act) with respect to any Voting
Securities, other than a group consisting of the Carlyle Entities and their
Affiliates or pursuant to the Voting Agreement, dated as of July 16, 2002;

                  (g) make a public request to the Company (or its directors,
officers, stockholders, employees or agents) to take any action in respect of
the foregoing matters (other than any such action in furtherance of the election
to the Board of the person designated by the Carlyle Entities pursuant to
Section 2 hereof or pursuant to the Certificate of Designations for the Series E
Senior Cumulative Convertible Participating Preferred Stock);

                  (h) publicly disclose any intention, plan or arrangement
inconsistent with the foregoing; or

                  (i) request or propose that the Company or any Representative
of the Company amend or waive any provision set forth in this Section 3.

         4. RESTRICTIONS ON TRANSFERS. Each Carlyle Entity agrees that it shall
not, directly or indirectly, sell or transfer beneficial ownership of any Voting
Securities (other than to the Company or any person or group approved by the
Company, which approval shall not be unreasonably withheld or delayed) if, as a
result of such sale or transfer, the transferee, together with its Affiliates,
would beneficially own 15% percent or more of the Voting Securities; provided,
however, that such sale or transfer shall not require the consent of the Company
if: (i) such transferee agrees to hold all Voting Securities subject to the
provisions of Sections 3 and 4 of this Agreement; (ii) such sale or transfer is
made pursuant to a bona fide public offering registered under the Securities Act
of 1933, as amended (the "1933 ACT"), or one or more "block trades" or brokerage
transactions pursuant to a registration statement filed pursuant to the 1933
Act; provided that, to the knowledge of the Carlyle Entities, no single
transferee will, upon


                                       4.

completion of such block trade or brokerage transaction, beneficially own more
than 15% of the Company's Voting Securities; (iii) such sale or transfer is made
pursuant to Rule 144 under the 1933 Act; or (iv) such sale or transfer is made
in response to an offer to purchase or exchange any Voting Securities for cash
or other consideration.

         5. SPECIFIC PERFORMANCE. Each of the Carlyle Entities and the Company
acknowledges that the other party would not have an adequate remedy at law for
money damages if any of the covenants or agreements of the other party in this
Agreement were not performed in accordance with its terms and therefore agrees
that the other party shall be entitled to specific enforcement of such covenants
or agreements and to injunctive and other equitable relief in addition to any
other remedy to which it may be entitled, at law or in equity.

         6. TERMINATION. This Agreement shall terminate upon the occurrence of
any of the following:

                  (a) the written agreement of the Company and the Carlyle
Entities to terminate this Agreement; or

collectively own less than 10% of the Voting Securities (assuming conversion of
all outstanding shares of Series D Senior Convertible Participating Preferred
Stock and Series E Senior Cumulative Convertible Participating Preferred Stock
into the Company's Common Stock).

         7. NOTICES. All notices, requests, claims, demands and other
