<PAGE>

                                                                               4

                                                                               6

            Section 4.2 Registration Statement.

            (a) The Company shall prepare and file a Form S-3 identifying each
      Purchaser as the "selling shareholders" with respect to the Shares with
      the Securities and Exchange Commission (the "Commission") within 30 days
      following the Closing Date;

            (b) The Company shall use its reasonable commercial efforts to have
      the Form S-3 declared effective by the Commission not later than the
      earlier to occur of:

            (i) the 105th day following the date on which the Form S-3 is filed
      with the Commission, if the Form S-3 is reviewed by the Commission, or

            (ii) fourteen (14) days following the Company's receipt of a
      no-review letter from the Commission relating to the Form S-3;

      provided, however, the Company shall not incur liability if the time
      period set forth in clause 4.2 (b)(i) above is not met.

            (c) The Company shall use its reasonable efforts to keep the Form
      S-3 continuously effective and upon the occurrence of any event that would
      cause the Form S-3 or the prospectus contained therein (A) to contain an
      untrue statement of a material fact or omit to state a material fact
      required to be stated therein or necessary to make the statements therein
      not misleading or (B) not to be effective and usable for resale of the
      Shares, the Company shall promptly notify Purchaser and file an
      appropriate amendment to the Form S-3, a supplement to the prospectus or a
      report filed with the Commission pursuant to Section 13(a), 13(c), 14 or
      15(d) of the Securities Exchange Act of 1934 (the "Exchange Act"), in the
      case of clause (A), correcting any such misstatement or omission, and, in
      the case of either clause (A) or (B), use its reasonable efforts to cause
      such amendment to be declared effective and the Form S-3 and the related
      prospectus to become usable for their intended purposes as soon as
      practicable thereafter, for a period not exceeding the earlier of:

            (i) the date of the second anniversary of the Closing Date;

            (ii) the date when the Purchasers are able to sell all the Shares
      immediately without restriction pursuant to the volume restriction
      limitations of Rule 144 under the Securities Act ("Rule 144"); or

            (iii) the date when all of the Shares held by the Purchasers have
      been disposed of in accordance with the Form S-3 or Rule 144.

      Notwithstanding the foregoing, the Company may suspend the availability of
      the Form S-3 by written notice to the Purchasers by sending notice to
      Wellington Management to the address provided in Section 6.1 of this
      Agreement, for a period not to exceed an aggregate of 45 days in any
      120-day period (each such period, a "Suspension Period") if:

<PAGE>

                                                                               7

                  (x) an event occurs and is continuing as a result of which the
            Form S-3, the Prospectus, any amendment or supplement thereto, or
            any document incorporated by reference therein would, in the
            Company's judgment based on the advice of counsel, contain an untrue
            statement of a material fact or omit to state a material fact
            required to be stated therein or necessary to make the statements
            therein not misleading; and

                  (y) (i) the Company determines in good faith that the
            disclosure of such event at such time would be detrimental to the
            Company and its subsidiaries or (ii) the Company needs additional
            time for the preparation of the necessary corrective disclosure,
            provided that in the case of clause (ii), the Suspension Period
            shall be no longer than is reasonably required for the Company to
            prepare and file the necessary corrective disclosure in order to
            cause the Form S-3 and related Prospectus to become usable for their
            intended purposes;

      provided, that, in the event the disclosure relates to a previously
      undisclosed proposed or pending material business transaction, the
      disclosure of which the Company determines in good faith would be
      reasonably likely to impede the Company's ability to consummate such
      transaction, the Company may extend a Suspension Period from 45 days to 60
      days; provided, however, that Suspension Periods shall not exceed an
      aggregate of 90 days in any 360-day period. The Company shall not be
      required to specify in the written notice to the Purchaser the nature of
      the event giving rise to the Suspension Period.

            (d) The Company shall notify each Purchaser promptly when the Form
S-3 is declared effective by the SEC, and furnish such number of prospectuses,
including preliminary prospectuses, and other documents incident thereto as such
Purchaser may reasonably request from time to time;

            (e) The Company shall use its best efforts to register or qualify
such Shares under such other securities or blue sky laws of such jurisdictions
of the United States where an exemption is not available and as Purchaser may
reasonably request to enable it to consummate the disposition in such
jurisdiction of the Shares (provided that the Company will not be required to
(A) qualify generally to do business in any jurisdiction where it would not
otherwise be required to qualify but for this provision, or (B) consent to
general service of process in any such jurisdiction, or (C) subject itself to
taxation in any jurisdiction where it is not already subject to taxation);

            (f) The Company shall cause all such Shares to be listed on each
securities exchange on which similar securities issued by the Company are then
listed and obtain all necessary approvals from the New York Stock Exchange for
trading thereon; and

            (g) Upon the sale of any Shares pursuant to the Form S-3, the
Company shall direct the transfer agent to remove all restrictive legends from
all certificates or other instruments evidencing the Shares.

<PAGE>

                                                                               8

            Section 4.3 Rule 144A and Rule 144. The Company agrees with the
Purchasers that, for so long as any Shares remain outstanding and during any
period in which the Company (i) is not subject to Section 13 or 15(d) of the
Exchange Act, to make available, upon request of the Purchasers, to the
Purchasers or beneficial owner of the Shares in connection with any sale thereof
and any prospective purchaser of such Shares designated by the Purchasers or
beneficial owner, the information required by Rule 144A(d)(4) under the
Securities Act in order to permit resales of such Shares pursuant to Rule 144A
under the Securities Act, and (ii) is subject to Section 13 or 15(d) of the
Exchange Act, to make all filings required thereby in a timely manner in order
to permit resales of such Shares pursuant to Rule 144.

            Section 4.4 Removal of Restrictions on Transfer of Shares. Any
legend referred to in Section 4.1 hereof stamped on a certificate evidencing the
Shares with respect to such Shares shall be removed and the Company shall issue
a certificate without such legend to the holder of such Shares if such Shares
are registered under the Securities Act, or if such holder provides the Company
with an opinion of counsel reasonably acceptable to the Company to the effect
that a public sale or transfer of such security may be made without registration
under the Securities Act or such holder provides the Company with other
reasonable assurances that the Company may request.

            Section 4.5 Expenses. The Company shall bear the following expenses
incident to the Company's performance of or in connection with the preparation
and filing of the Form S-3, regardless of whether a Form S-3 becomes effective:

            (a) all registration and filing fees and expenses (including filings
      made with the NASD);

            (b) all expenses of printing (including any printing of
      prospectuses) and the Company's expenses for messenger and delivery
      services and telephone;

            (c) all fees and disbursements of counsel to the Company; and

            (d) all fees and expenses of the Company's accountants.

The Company shall not bear any fees or expenses related to underwriting
discounts or commissions, brokers' fees and similar selling expenses, and any
other fees and expenses incurred by the Purchasers, including, without
limitation, all fees and disbursements of counsel to the Purchasers.

            Section 4.6 Filing of Form 8-K; Press Release. Within four (4)
business days following the date hereof, the Company shall file a Form 8-K with
the Commission (the "8-K") describing the terms of the transactions contemplated
herein. The Company shall issue a press release or other announcement of this
Agreement or the transactions contemplated hereby within 48 hours following the
date hereof. Notwithstanding the foregoing, the Company and the Purchasers agree
that such press release shall be subject to mutual agreement and that, except to
the extent required under applicable law or the requirements of a stock exchange
or other applicable self-regulatory

            ARTICLE 5. INDEMNIFICATION

            Section 5.1 Indemnification

            (a) The Company will indemnify and hold harmless each Purchaser
      whose Shares are included in a registration pursuant to the provisions of
      Section 4.2, each officer, director and affiliate (as defined in Rule
      501(b) of Regulation D under the Securities Act) of such Purchaser, and
      each person, if any, who controls such Purchaser within the meaning of the
      Securities Act (a "controlling person"), from and against any and all
      loss, damage, liability, cost and expense to which such Purchaser,
      director, officer, affiliate, or controlling person may become subject
      under the Securities Act or otherwise, insofar as such losses, damages,
      liabilities, costs or expenses are caused by any untrue statement or
      alleged untrue statement of any material fact contained in the Form S-3,
      any final prospectus relating thereto or any amendment or supplement
      thereto, or arise out of or are based upon the omission or alleged
      omission to state therein a material fact required to be stated therein or
      necessary to make the statements therein, in light of the circumstances in
      which they were made, not misleading; provided, however, that the Company
      will not be liable in any such case to the extent that any such loss,
      damage, liability, cost or expense arises out of or is based upon an
      untrue statement or alleged untrue statement or omission or alleged
      omission so made in reliance upon written information furnished by such
      Purchaser or any person who controls the Purchaser in writing specifically
      for use in the preparation thereof.

            (b) Each Purchaser whose Shares are included in a registration
      pursuant to Section 4.2 will indemnify and hold harmless the Company, any
      director or officer thereof, and any controlling person of the Company
      from and against any and all loss, damage, liability, cost or expense to
      which the Company or such director, officer, or controlling person may
      become subject under the Securities Act or otherwise, insofar as such
      losses, damages, liabilities, costs or expenses are caused by any untrue
      or alleged untrue statement of any material fact contained in the Form
      S-3, any final prospectus relating thereto or any amendment or supplement
      thereto, or arise out of or are based upon the omission or the alleged
      omission to state therein a material fact required to be stated therein or
      necessary to make the statements therein, in light of the circumstances in
      which they were made, not misleading, in each case to the extent such
      untrue statement or alleged untrue statement or omission or alleged
      omission was so made primarily in reliance upon written information
      furnished by such Purchaser, or Wellington Management, specifically for
      use in the preparation thereof.

            (c) Promptly after receipt by an indemnified party pursuant to the
      provisions of subparagraph (a) or (b) of this Section 5.1 of notice of the
      commencement of any action involving the subject matter of the foregoing
      indemnity provisions, such indemnified party will, if a claim thereof is
      to be made against the indemnifying party pursuant to the provisions of
      said subparagraphs (a) or (b), promptly notify the indemnifying party of
      the commencement

                                                                              10

      thereof; but the omission to so notify the indemnifying party will not
      relieve it from any liability which it may have to any indemnified party
      under this Section 5.1, except to the extent the indemnifying party was
      prejudiced by such omission. In case such action is brought against any
      indemnified party and it notifies the indemnifying party of the
      commencement thereof, the indemnifying party shall have the right to
      participate in, and, to the extent that it may wish, jointly with any
      other indemnifying party similarly notified, to assume the defense
      thereof, with counsel reasonably satisfactory to such indemnified party;
      provided, however, that if the defendants in any action include both the
      indemnified party and the indemnifying party and there is a conflict of
      interest which would prevent counsel for the indemnifying party from also
      representing the indemnified party, the indemnified party or parties shall
      have the right to select one firm of separate counsel satisfactory to the
      indemnifying party to participate in the defense of such action on behalf
      of all indemnified parties. After notice from the indemnifying party to
      such indemnified party of its election so to assume the defense thereof,
      the indemnifying party will not be liable to such indemnified party
      pursuant to the provisions of said subparagraphs (a) or (b) of this
      Section 5.1 for any legal or other expense subsequently incurred by such
      indemnified party in connection with the defense thereof, other than
      reasonable out of pocket costs of investigation, unless (i) the
      indemnified party shall have employed counsel in accordance with the
      proviso of the preceding sentence, in which case only the reasonable fees
      and expenses of such single firm shall be indemnifiable; or (ii) the
      indemnifying party shall not have employed counsel reasonably satisfactory
      to the indemnified party to represent the indemnified party within a
      reasonable time after the notice of the commencement of the action.

            (d) The obligations of the parties under this Section 5.1 shall be
      in addition to any liability, which any party may otherwise have to any
      other party.
