     Securities" shall mean Registrable Securities constituting Investor

          any registration statement pertaining to an underwritten public
          offering of securities of the Company for its own account (other than
          a Rule 145 Transaction, or a registration relating solely to employee
          benefit plans);

               (b) (i) On any form other than Form S-3 (or any successor form)
          if the Company has previously effected five or more registrations of

          the good faith judgment of the Board it would be seriously detrimental
          to the Company and its shareholders for such Registration Statement to
          be filed at the date filing would have been required, in which case
          the Company shall have an additional period of not more than 60 days
          within which to file such Registration Statement; provided, however,
                                                            --------  -------

          the anticipated aggregate offering price to the public of the
          Registrable Securities to be included in the registration by all
          holders is less than $5,000,000; or

          Offering.

          8.1.1.1.  Form.  Except as otherwise provided above, each registration
                    ----
     requested pursuant to this Section 8.1.1 shall be effected by the filing of
     a registration statement on Form S-1 (or any other form which includes
     substantially the same information as would be required to be included in a
     registration statement on such form as currently constituted), unless the
     use of a different form has been agreed to in writing by holders of at
     least a majority of the Registrable Investor Securities to be included in
     the proposed registration statement in question (the "Majority
                                                           --------
     Participating Investors").
     -----------------------

          8.1.2.    Payment of Expenses.  The Company shall pay all reasonable
                    -------------------
     expenses of holders of Investor Shares incurred in connection with each
     registration of Registrable Securities requested pursuant to this Section
     8.1, other than underwriting discount and commission, if any, and

     Investors shall request that such registration shall be effected pursuant
     to an underwritten offering, the Company

                                      -4-
<PAGE>

     shall include such information in the written notices to holders of
     Registrable Securities referred to in Section 8.3. In such event, the right
     of any holder of Registrable Securities to have securities owned by such
     holder included in such registration pursuant to Section 8.1 shall be
     conditioned upon such holder's participation in such underwriting and the
     inclusion of such holder's Registrable Securities in the underwriting
     (unless otherwise mutually agreed upon by the Majority Participating
     Investors and such holder) to the extent provided herein. If requested by
     such underwriters, the Company together with the holders of Registrable
     Securities proposing to distribute their securities through such
     underwriting will enter into an underwriting agreement with such
     underwriters for such offering containing such representations and
     warranties by the Company and such holders and such other terms and
     provisions as are customarily contained in underwriting agreements with
     respect to secondary distributions, including, without limitation,

     Agreement, "Registrable Other Securities" shall mean Registrable Securities

     Securities which the Company has been requested to register pursuant to
     Section 8.3 (which request shall specify the intended method of disposition
     of such Registrable Securities), all to the extent requisite to permit the
     disposition (in accordance with the intended methods thereof as aforesaid)

          Initiating Other Investors to include in such registration at least
          90% of the Registrable Securities which they desired to

                                      -5-

          the Company shall have an additional period of not more than 60 days
          within which to file such Registration Statement; provided, however,
                                                            --------  -------
          that the Company shall not so postpone a registration pursuant to this
          clause (d) more than once in any twelve month period;

the Company shall include such information in the written notices to holders of

     Section 8.3.1.1, except as provided in Section 8.2A.1, no holder of
     Registrable Securities shall have the right to have any such Registrable
     Securities included in a registration requested pursuant to Section 8.2A.1.

     8.3. Piggyback Registration Rights.
          -----------------------------

          8.3.1.   Piggyback Registration.
                   ----------------------

                   8.3.1.1.  General.  Each time the Company proposes to
                             -------
          register any shares of Common Stock under the Securities Act on a form
          which would permit registration of Registrable Securities for sale to
          the public, for its own account or for the account of any holder of
          its shares of Common Stock, for sale in a Public Offering, the Company
          will give notice to all holders of shares of Common Stock of its
          intention to do so. Any such holder may, by written response delivered
          to the Company within 20 days after the effectiveness of such notice,
          request that all or a specified part of the Registrable Securities
          held by such holder be included in such registration. The Company
          thereupon will use its reasonable efforts to cause to be included in
          such registration under the Securities Act all shares of Common Stock
          which the Company has been so requested to register by such holders,
          to the extent required to permit the disposition (in accordance with
          the methods to be used by the Company or other holders of shares of
          Common Stock in such Public Offering) of the Registrable Securities to
          be so registered. No registration of Registrable Securities effected
          under this Section 8.3 shall relieve the Company of any of its
          obligations to effect registrations of Registrable Securities pursuant
          to Section 8.1 hereof.

               8.3.1.2.  Excluded Transactions.  The Company shall not be
                         ---------------------
          obligated to effect any registration of Registrable Securities under
          this Section 8.3 incidental to the registration of any of its
          securities in connection with:

                      (a)   Any Public Offering relating to employee benefit
                  plans or dividend reinvestment plans;

                      (b)   Any Public Offering relating to the acquisition or
                  merger after the date of the Original Agreement by the Company
                  or any of its subsidiaries of or with any other businesses; or

                      (c)   Any Public Offering initiated by the NatWest
                  Investors pursuant to Section 8.2A.1.

          8.3.2.  Payment of Expenses.  The Company shall pay all reasonable
                  -------------------
     expenses of holders of Registrable Securities incurred in connection with
     each registration of Registrable Securities requested pursuant to this
     Section 8.3, other than underwriting discount and commission, if any, and
     applicable stamp or transfer taxes, if any; provided, however, that the
                                                 --------  -------
     Company shall not be required to pay in respect of the fees and expenses of
     any attorneys or other advisers retained by such holders more than an
     aggregate for all such holders of $25,000 in the case of each such
     registration.

          8.3.3.  Additional Procedures.  Holders of Shares participating in any
                  ---------------------
     Public Offering pursuant to this Section 8.3 shall take all such actions
     and execute all such documents and instruments that are reasonably
     requested by the Company to effect the sale of their Shares in such Public
     Offering, including, without limitation, being parties to the underwriting
     agreement entered into by the Company and any other selling shareholders in
     connection therewith and being liable in respect of the representations and
     warranties by, and the other agreements (including customary selling
     stockholder indemnifications and "lock-up" agreements) on the part of, the
     Company and any other selling shareholders to and for the benefit of the
     underwriters in such underwriting agreement; provided, however, that (i)
                                                  --------  -------
     with respect to individual representations, warranties and agreements of
     sellers of Shares in such Public Offering, the aggregate amount of such
     liability shall not exceed such holder's net proceeds from such offering
     and (ii) with respect to all other representations, warranties and
     agreements of sellers of shares in such Public Offering, the aggregate
     amount of such liability shall not exceed the lesser of (a) such holder's
     pro rata portion of any such liability, in accordance with such holder's
     portion of the total number of Shares included in the offering or (b) such
     holder's net proceeds from such offering.

     8.4  Certain Other Provisions.
          ------------------------

          8.4.1  Underwriter's Cutback.  In connection with any registration of
                 ---------------------
     shares in an underwritten offering, the underwriter may determine that
     marketing factors (including, without limitation, an adverse effect on the
     per share offering price) require a limitation of the number of shares to
     be underwritten.  Notwithstanding any contrary provision of this Section 8
     and subject to the terms of this Section 8.4.1, the underwriter may limit
     the number of shares which would otherwise be included in such registration
     by excluding any or all Registrable Securities from such registration (it
     being understood that the number of shares which the Company seeks to have
     registered in such registration shall not be subject to exclusion, in whole
     or in part, under this Section 8.4.1).  Upon receipt of notice from the
     underwriter of the need to reduce the number of shares to be included in
     the registration, the Company shall advise all holders of the Company's
     securities that would otherwise be registered and underwritten pursuant
     hereto, and the number of shares of such securities, including Registrable
     Securities, that may be included in the registration shall be allocated in
     the following manner, unless the underwriter shall determine that marketing
     factors require a different allocation:  shares, other than Registrable
     Securities, requested to be included in such registration by shareholders
     shall be excluded; and, if a limitation on the number of shares is still
     required, the number of Registrable Securities that may be included in such
     registration shall be allocated among the holders thereof in proportion, as
     nearly as practicable, to the respective amounts of Registrable Securities
     which each such holder requested be registered in such registration.  For
     purposes of any underwriter cutback, all Registrable Securities held by any
     holder of Registrable Securities which is a partnership, corporation or
     limited liability company shall also include any Registrable Securities
     held by the partners, retired partners, shareholders, members or affiliated
     entities of such holder, or the estates and family members of any such
     partners, retired partners and members and any trusts for the benefit of
     any of the foregoing persons, and such holder and other persons shall be
     deemed to be a single selling holder, and any pro rata reduction with
     respect to such selling holder shall be based upon the aggregate amount of
     Registrable Securities owned by all entities and individuals included in
     such selling holder, as defined in this sentence.  No securities excluded
     from the underwriting by reason of the underwriter's marketing limitation
     shall be included in such registration.  If any holder of Registrable
     Securities disapproves of the terms of the underwriting, it may elect to
     withdraw therefrom by written notice to the Company and the underwriter.
     The Registrable Securities so withdrawn shall also be withdrawn from
     registration.

          8.4.2.  Other Actions.  If and in each case when the Company is
                  -------------
     required to use its best efforts to effect a registration of any
     Registrable Securities as provided in this Section 9, the Company shall
     take appropriate and customary actions in furtherance thereof, including,
     without limitation: (i) promptly filing with the Commission a registration
     statement and using reasonable efforts to cause such registration statement


                                      -10-
<PAGE>

     to become effective, (ii) preparing and filing with the Commission such
     amendments and supplements to such registration statements as may be
     required to comply with the Securities Act and to keep such registration
     statement effective for a period not to exceed 270 days (or 30 days in the
     case of a registration statement filed pursuant to Section 8.2A) from the
     date of effectiveness or such earlier time as the Registrable Securities
     covered by such registration statement shall have been disposed of in
     accordance with the intended method of distribution therefor or the
     expiration of the time when a prospectus relating to such registration is
     required to be delivered under the Securities Act, (iii) use its best
     efforts to register or qualify such Registrable Securities under the state
     securities or "blue sky" laws of such jurisdictions as the sellers shall
     reasonably request; provided, however, that the Company shall not be
                         --------  -------
     obligated to file any general consent to service of process or to qualify
     as a foreign corporation in any jurisdiction in which it is not so
     qualified or to subject itself to taxation in respect of doing business in
     any jurisdiction in which it would not otherwise be so subject; and (iv)
     otherwise cooperate reasonably with, and take such customary actions as may
     reasonably be requested by the holders of Registrable Securities in
     connection with, such registration.

          8.4.3.  Selection of Underwriters and Counsel.  The underwriters and
                  -------------------------------------
     legal counsel to be retained in connection with any Public Offering shall
     be selected by the Board or, in the case of an offering following a request
     therefor under Section 8.1.1, the Initiating Investors.

          8.4.4.  Lock-Up.  Without the prior written consent of the
                  -------
     underwriters managing any Public Offering, for a period beginning seven
     days immediately preceding and ending on (a) in the case of the IPO, the
     180th day following the effective date of the registration statement used
     in connection with such offering or (b) in the case of any Public Offering
     that is not the IPO or effected pursuant to Section 8.2A, the 90th day
     following the effective date of the registration statement used in
     connection with such offering, no holder of Shares (whether or not a
     selling shareholder pursuant to such registration statement) shall Transfer
     any Common Stock except pursuant to such registration statement or to a
     Permitted Transferee in accordance with the terms of this Agreement.

     8.5. Indemnification and Contribution.
          --------------------------------

          8.5.1.  Indemnities of the Company.  In the event of any registration
                  --------------------------
     of any Registrable Securities or other debt or equity securities of the
     Company or any of its subsidiaries under the Securities Act pursuant to
     this Section 9 or otherwise, and in connection with any registration
     statement or any other disclosure document produced by or on behalf of the
     Company or any of its subsidiaries including, without limitation, reports
     required and other documents filed under the Exchange Act, and other
     documents pursuant to which any debt or equity securities of the Company or
     any of its

                                      -11-
<PAGE>

     subsidiaries are sold (whether or not for the account of the Company or its
     subsidiaries), the Company will, and hereby do, and will cause each of
     their respective subsidiaries, jointly and severally to, indemnify and hold
     harmless each seller of Registrable Securities, any Person who is or might
     be deemed to be a controlling Person of the Company or any of its
     subsidiaries within the meaning of Section 15 of the Securities Act or
     Section 20 of the Exchange Act, their respective direct and indirect
     partners, advisory board members, directors, officers, trustees, members
     and shareholders, and each other Person, if any, who controls any such
     seller or any such holder within the meaning of Section 15 of the
     Securities Act or Section 20 of the Exchange Act (each such person being
     referred to herein as a "Covered Person"), against any losses, claims,
                              --------------
     damages or liabilities, joint or several, to which such Covered Person may
     be or become subject under the Securities Act, the Exchange Act, any other
     securities or other law of any jurisdiction, the common law or otherwise,
     insofar as such losses, claims, damages or liabilities (or actions or
     proceedings in respect thereof) arise out of or are based upon (i) any
     untrue statement or alleged untrue statement of any material fact contained
     or incorporated by reference in any registration statement under the
     Securities Act, any preliminary prospectus or final prospectus included
     therein, or any related summary prospectus, or any amendment or supplement
     thereto, or any document incorporated by reference therein, or any other
     such disclosure document (including without limitation reports and other
     documents filed under the Exchange Act and any document incorporated by
     reference therein) or other document or report, (ii) any omission or
     alleged omission to state therein a material fact required to be stated
     therein or necessary to make the statements therein not misleading or (iii)
     any violation or alleged violation by the Company or any of its
     subsidiaries of any federal, state, foreign or common law rule or
     regulation applicable to the Company or any of its subsidiaries and
     relating to action or inaction in connection with any such registration,
     disclosure document or other document or report, and will reimburse such
     Covered Person for any legal or any other expenses incurred by it in
     connection with investigating or defending any such loss, claim, damage,
     liability, action or proceeding; provided, however, that neither the
                                      --------  -------
     Company nor any of its subsidiaries shall be liable to any Covered Person
     in any such case to the extent that any such loss, claim, damage,
     liability, action or proceeding arises out of or is based upon an untrue
     statement or alleged untrue statement or omission or alleged omission made
     in such registration statement, any such preliminary prospectus, final
     prospectus, summary prospectus, amendment or supplement, incorporated
     document or other such disclosure document or other document or report, in
     reliance upon and in conformity with written information furnished to the
     Company or to any of its subsidiaries through an instrument duly executed
     by such Covered Person specifically stating that it is for use in the
     preparation thereof. The indemnities of the Company and of its subsidiaries
     contained in this Section 8.5.1 shall remain in full force and effect
     regardless of any investigation made by or on behalf of such Covered Person
     and shall survive any transfer of securities.

                                      -12-
<PAGE>

          8.5.2  Indemnities to the Company.  The Company and any of its
                 --------------------------
     subsidiaries may require, as a condition to including any securities in any
     registration statement filed pursuant to this Section 9, that the Company
     and any of its subsidiaries shall have received an undertaking satisfactory
     to it from the prospective seller of such securities, to indemnify and hold
     harmless the Company and any of its subsidiaries, each director of the
     Company or any of its subsidiaries, each officer of the Company or any of
     its subsidiaries who shall sign such registration statement and each other
     Person (other than such seller), if any, who controls the Company and any
     of its subsidiaries within the meaning of Section 15 of the Securities Act
     or Section 20 of the Exchange Act with respect to any statement in or
     omission from such registration statement, any preliminary prospectus or
     final prospectus included therein, or any amendment or supplement thereto,
     or any other disclosure document (including, without limitation, reports
     and other documents filed under the Exchange Act or any document
     incorporated therein) or other document or report, if such statement or
     omission was made in reliance upon and in conformity with written
     information furnished to the Company or any of its subsidiaries through an
     instrument executed by such seller specifically stating that it is for use
     in the preparation of such registration statement, preliminary prospectus,
     final prospectus, summary prospectus, amendment or supplement, incorporated
     document or other document or report.  Such indemnity shall remain in full
     force and effect regardless of any investigation made by or on behalf of
     the Company, any of its subsidiaries or any such director, officer or
     controlling Person and shall survive any transfer of securities.

          8.5.3  Indemnification Procedures.  Promptly after receipt by a Person
                 --------------------------
     entitled to indemnification pursuant to the foregoing provisions of this
     Section 8.5 (an "Indemnitee") of notice of the commencement of any action
                      ----------
     or proceeding involving a claim of the type referred to in the foregoing
     provisions of this Section 8.5, such Indemnitee will, if a claim in respect
     thereof is to be made by such Indemnitee against any indemnifying party,
     give written notice to each such indemnifying party of the commencement of
     such action; provided, however, that the failure of any Indemnitee to give
                  --------  -------
     notice to such indemnifying party as provided herein shall not relieve any
     indemnifying party of its obligations under the foregoing provisions of
     this Section 8.5, except and solely to the extent that such indemnifying
     party is actually and materially prejudiced by such failure to give notice.
     In case any such action is brought against an Indemnitee, each indemnifying
     party will be entitled to participate in and to assume the defense thereof,
     jointly with any other indemnifying party similarly notified, to the extent
     that it may wish, with counsel reasonably satisfactory to such Indemnitee
     (who shall not, except with the consent of the Indemnitee, be counsel to
     such an indemnifying party), and after notice from an indemnifying party to
     such Indemnitee of its election so to assume the defense thereof, such
     indemnifying party will not be liable to such Indemnitee for any legal or
     other expenses subsequently incurred by the latter in connection with the
     defense thereof; provided, however, that (i) if the Indemnitee reasonably
                      --------  -------
     determines that there may be a conflict between the positions of such


                                      -13-
<PAGE>

     indemnifying party and the Indemnitee in conducting the defense of such
     action or if the Indemnitee reasonably concludes that representation of
     both parties by the same counsel would be inappropriate due to actual or
     potential differing interests between them, then counsel for the Indemnitee
     shall conduct the defense to the extent reasonably determined by such
     counsel to be necessary to protect the interests of the Indemnitee and such
     indemnifying party shall employ separate counsel for its own defense, (ii)
     in any event, the Indemnitee shall be entitled to have counsel chosen by
     such Indemnitee participate in, but not conduct, the defense and (iii) the
     indemnifying party shall bear the legal expenses incurred in connection
     with the conduct of, and the participation in, the defense as referred to
     in clauses (i) and (ii) above.  If, within a reasonable time after receipt
     of the notice, such indemnifying party shall not have elected to assume the
     defense of the action, such indemnifying party shall be responsible for any
     legal or other expenses incurred by such Indemnitee in connection with the
     defense of the action, suit, investigation, inquiry or proceeding.  No
     indemnifying party will consent to entry of any judgment or enter into any
     settlement which does not include as an unconditional term thereof the
     giving by the claimant or plaintiff to such Indemnitee of a release from
     all liabilities in respect of such claim or litigation.

          8.5.4.  Contribution.  If the indemnification provided for in Sections
                  ------------
     8.5.1 or 8.5.2 hereof is unavailable to a party that would have been an
     Indemnitee under any such Section in respect of any losses, claims, damages
     or liabilities (or actions or proceedings in respect thereof) referred to
     therein, then each party that would have been an indemnifying party
     thereunder shall, in lieu of indemnifying such Indemnitee, contribute to
     the amount paid or payable by such Indemnitee as a result of such losses,
     claims, damages or liabilities (or actions or proceedings in respect
     thereof) in such proportion as is appropriate to reflect the relative fault
     of such indemnifying party on the one hand and such Indemnitee on the other
     in connection with the statements or omissions which resulted in such
     losses, claims, damages or liabilities (or actions or proceedings in
     respect thereof).  The relative fault shall be determined by reference to,
     among other things, whether the untrue or alleged untrue statement of a
     material fact or the omission or alleged omission to state a material fact
     relates to information supplied by such indemnifying party or such
     Indemnitee and the parties' relative intent, knowledge, access to
     information and opportunity to correct or prevent such statement or
     omission.  The parties agree that it would not be just or equitable if
     contribution pursuant to this Section 8.5.4 were determined by pro rata
     allocation or by any other method of allocation which does not take account
     of the equitable considerations referred to in the preceding sentence.  The
     amount paid or payable by a contributing party as a result of the losses,
     claims, damages or liabilities (or actions or proceedings in respect
     thereof) referred to above in this Section 8.5.4 shall include any legal or
     other expenses reasonably incurred by such Indemnitee in connection with
     investigating or defending any such action or claim.  No Person guilty of
     fraudulent misrepresentation (within the meaning of Section 11(f) of the
     Securities Act) shall be

                                      -14-
<PAGE>

     entitled to contribution from any Person who was not guilty of such
     fraudulent misrepresentation.

          8.5.5.  Limitation on Liability of Holders of Registrable Securities.
                  ------------------------------------------------------------
     The liability of each holder of Registrable Securities in respect of any
     indemnification or contribution obligation of such holder arising under
     this Section 8.5 shall not in any event exceed an amount equal to the net
     proceeds to such holder (after deduction of all underwriters' discounts and
     commissions) from the disposition of the Registrable Securities disposed of
     by such holder pursuant to such registration.

9.   TRANSFERS TO OTHER HOLDERS.  Shares Transferred by a holder of Shares to
another holder of Shares under this Agreement shall be deemed for all purposes
hereof to be Investor Shares, Other Shares, Management Shares or Employee Shares
hereunder, as the case may be, of like kind with the other Shares held by such
acquiring holder.

10.  REMEDIES.

     10.1.  Generally.  The Company and each holder of Shares shall have all
            ---------
remedies available at law, in equity or otherwise in the event of any breach or
violation of this Agreement or any default hereunder by the Company or any
holder of Shares.  The parties acknowledge and agree that in the event of any
breach of this Agreement, in addition to any other remedies which may be
available, each of the parties hereto shall be entitled to specific performance
of the obligations of the other parties hereto and, in addition, to such other
equitable remedies (including, without limitation, preliminary or temporary
relief) as may be appropriate in the circumstances.

     10.2. [RESERVED]
           ----------

11.  LEGENDS.

     11.1.  [Reserved].
            ----------

     11.2.  1933 Act Legends.  Each certificate representing Shares shall have
            ----------------
the following legend endorsed conspicuously thereupon:


            The securities represented by this certificate were issued in a
     private placement, without registration under the Securities Act of 1933,
     as amended (the "Act"), and may not be sold, assigned, pledged or otherwise
     transferred in the absence of an effective registration under the Act
     covering the transfer or an opinion of counsel, satisfactory to the issuer,
     that registration under the Act is not required.

     11.3.  Stop Transfer Instruction.  The Company will instruct any transfer
            -------------------------
agent not to register the Transfer of any Shares until the conditions specified
in the foregoing legend is satisfied.

     11.4.  Termination of Certain Restrictions. The legend set forth in Section
            -----------------------------------
11.2 shall cease to be required as to any particular Shares (i) when, in the
opinion of Ropes & Gray, or other counsel reasonably acceptable to the Company,
such restrictions are no longer required in order to assure compliance with the
Securities Act or (ii) when such Shares have been effectively registered under
the Securities Act or transferred pursuant to Rule 144. Wherever (i) such
