effective subject to and commencing as of the Closing Date (as such term is
defined in the Stock Purchase Agreement (as hereinafter defined)) (the
"EFFECTIVE DATE").

                                    RECITALS

            WHEREAS, the Company and Purchaser are parties to a certain Common
Stock Purchase Agreement of even date herewith (the "STOCK PURCHASE AGREEMENT")
pursuant to which the Company has agreed to issue and sell, and Purchaser has
agreed to purchase, up to 28,301,887 shares of Common Stock of the Company; and

            WHEREAS, in order to induce the Company to enter into the Stock
Purchase Agreement and to induce Purchaser to purchase shares of the Company's
Common Stock pursuant to the Stock Purchase Agreement, the Company and Purchaser
are entering into this Agreement to provide each other with certain assurances
and document certain other matters as set forth herein.

            NOW, THEREFORE, in consideration of the mutual covenants contained
in this Agreement, the Company and the Purchaser agree as follows:

                                    SECTION 1

                                   STANDSTILL

      1.1. STANDSTILL. Commencing as of the Effective Date and for so long as
the Purchaser beneficially owns (within the meaning of Rule 13d-3 under the
Securities Exchange Act of 1934, as amended (the "EXCHANGE ACT")) at least 5% of
the then outstanding Common Stock of the Company:

            (a) Purchaser (including all Affiliates) shall not acquire or agree
to acquire, publicly offer, or make any public proposal with respect to the
possible acquisition of "beneficial ownership" (within the meaning of Rule 13d-3
under the Exchange Act) of any voting securities of the Company, any securities
convertible into or exchangeable for voting securities of the Company, or any
other right to acquire voting securities of the Company, except by way of stock
dividends or other distributions or offerings made available to holders of
securities of the Company generally, from the Company or any other person or
entity, if after giving effect to such acquisition of additional shares, the
total beneficial ownership (within the meaning of Rule 13d-3 under the Exchange
Act) of Purchaser (together with all of its Affiliates) shall be greater than
the Permitted Percentage (as such term is defined in the Rights Agreement dated
as of February 1, 1999 between the Company and American Stock Transfer & Trust
Company, as Rights Agent, as amended) (the "BENEFICIAL OWNERSHIP LIMITATION")
without the prior written consent of the Company, which consent may be withheld
in its sole discretion; provided, however, that it shall not be a violation of
the prohibition contained in this Section 1.1(a) if Purchaser or any of its
Affiliates shall exceed the Beneficial Ownership Limitation solely as a

<Page>

result of an acquisition or retirement of shares of securities of the Company by
the Company which, by reducing the number of shares outstanding, increases the
proportionate number of shares of securities beneficially owned by Purchaser or
any of its Affiliates, provided that Purchaser and its Affiliates do not
thereafter acquire beneficial ownership of additional shares of securities of
the Company while still exceeding the Beneficial Ownership Limitation; and

            (b) neither Purchaser nor any Affiliate shall (i) make, or in any
way participate, directly or indirectly, in any "solicitation" of "proxies" to
vote (as such terms are used in the proxy rules of the Exchange Act) or seek to
advise, encourage or influence any person or entity with respect to the voting
of any shares of capital stock of the Company, initiate, propose or otherwise
solicit stockholders of the Company for the approval of one or more stockholder
proposals or induce or attempt to induce any other individual, firm,
corporation, partnership or other entity to initiate any stockholder proposal;
(ii) deposit any securities of the Company having the right to vote generally in
any election of directors of the Company ("VOTING STOCK") into a voting trust or
subject any shares of Voting Stock to any arrangement or agreement with respect
to the voting of such securities, where the activities of such voting trust,
arrangement or agreement would constitute a violation of the terms of this
Agreement; (iii) participate in a "13D Group" (as defined below) with respect to
any securities of the Company, where the activities of such 13D Group would
constitute a violation of the terms of this Agreement; (iv) make any public
announcement with respect to, or submit a proposal for, or offer of (with or
without conditions) any business combination, merger, acquisition,
restructuring, recapitalization, tender or exchange offer or other similar
transaction involving the Company, or its securities or a material portion of
its assets; (v) arrange, or in any way participate, directly or indirectly, in
any financing of a third party for the purchase by such party of any voting
securities or securities convertible or exchangeable into or exercisable for any
voting securities, or assets of the Company, except for such securities or
assets as are then being offered for sale by the Company or any of its
Affiliates; (vi) make any request or proposal to amend, waive or terminate any
provision of this paragraph; or (vii) initiate any discussions, negotiations,
arrangements or understandings with any third party with respect to the Company
in connection with any matters referred to in clauses (i) through (vi) above;
provided, however, that nothing in this Section 1.1(b), shall prohibit the
Purchaser from: (x) exercising its rights to designate members to the Company's
Board of Directors in accordance with Section 8.1 of the Stock Purchase
Agreement; or (y) voting its shares of Common Stock of the Company in favor of,
or seeking to advise, encourage or influence any person or entity solely with
respect to the voting of any shares of capital stock of the Company in favor of,
the election of the members designated in accordance with Section 8.1 of the
Stock Purchase Agreement or the matters recommended by the Board of Directors of
the Company in the proxy statement referenced in Section 8.3 of the Stock
Purchase Agreement. Each party agrees to promptly advise the other party of any
inquiry or proposal made by or to it with respect to any of the foregoing.

Agreement.

            (b) "PERSON" as used herein shall mean any individual, corporation,
partnership, firm, association, unincorporated organization, joint venture,
trust or other entity, and shall include any successor (by merger or otherwise)

formed for the purpose of acquiring, holding, voting or disposing of Voting

addition to all other remedies available to such party, each party shall be
entitled to specific performance and injunctive or other equitable relief as a
remedy for any breach of this Agreement. In addition, each party hereto further

waive, any requirement for the securing or posting of any bond in connection
with any breach or threatened breach of this Agreement.

      1.4. FIDUCIARY DUTY OF DIRECTORS. Notwithstanding anything to the contrary
in this Section 1, (i) the provisions of this Section 1 shall not limit or

of Directors pursuant to Section 8.1 of the Stock Purchase Agreement from taking
any actions (consistent with their fiduciary duty to the Company and its
stockholders) in their capacities as such members of the Company's Board of
Directors, and (ii) this Section 1 shall not affect the Company's obligations
under Section 8.1 of the Stock Purchase Agreement (relating to Board of Director
nominations).
