                                   ARTICLE II

                       CORPORATE GOVERNANCE AND MANAGEMENT

                  Section 2.1 COMPOSITION OF THE BOARD. The Board shall consist
of at least nine, but no more than ten, members (two of which shall be
individuals which are not "Affiliates" or "Associates" (as those terms are used
within the meaning of Rule 12b-2 of the General Rules and Regulations under the
Exchange Act) of any Shareholder or its Affiliates), of whom four shall be
nominated by THL, one shall be nominated by DLJMB, one shall be Paul M. Montrone
and one shall be Paul M. Meister. Each Shareholder entitled to vote for the
election of directors to the Board agrees that it will vote its shares of Common
Stock or execute consents, as the case may be, and take all other necessary
action (including causing the Company to call a special meeting of shareholders)
in order to ensure that the composition of the Board is as set forth in this
Section 2.1; provided that, no Shareholder shall be required to vote for another
Shareholder's nominee or Mr. Montrone or Mr. Meister if the number of shares of
Common Stock held by (i) Mr. Montrone and Mr. Meister collectively, or (ii) such
other Shareholder making the nomination collectively with its Affiliates, as
applicable, is, at the close of business on the day preceding such vote or
execution of consents, less than 10% of such party's or parties' Initial
Ownership of shares of Common Stock on a Fully Diluted basis; and, provided
further, that for so long as Messrs. Montrone and Meister collectively own 10%
or more of their collective Initial Ownership of shares of Common Stock on a
Fully Diluted basis, designees nominated by THL and the Equity Investors shall
be selected in good faith after consultation with Messrs. Montrone and Meister,
which consultation shall involve a consideration of Messrs. Montrone and
Meister's views relating to the Company. The initial Board after the execution
of this 



                                       16
<PAGE>   21

Agreement shall consist of the individuals listed on Schedule III hereto.

                  Section 2.2 REMOVAL. Each Shareholder agrees that if, at any
time, it is then entitled to vote for the removal of directors of the Company,
it will not vote any of its shares of Common Stock in favor of the removal of
any director who shall have been designated or nominated pursuant to Section 2.1
unless such removal shall be for Cause or such director or the Person(s)
entitled to designate or nominate such director shall have consented to such
removal in writing, provided that if the Persons entitled to designate or
nominate any director pursuant to Section 2.1 shall request the removal, with or
without Cause, of such director in writing, such Shareholder shall vote its
shares of Common Stock in favor of such removal. Removal for "Cause" shall mean
removal of a director because of such director's (a) willful and continued
failure substantially to perform his duties with the Company in his established
position, (b) willful conduct which is injurious to the Company or any of its
Subsidiaries, monetarily or otherwise, or (c) conviction for, or guilty plea to,
a felony or a crime involving moral turpitude.

                  Section 2.3 VACANCIES. If, as a result of death, disability,
retirement, resignation, removal (with or without Cause) or otherwise, there
shall exist or occur any vacancy on the Board:

                  (a) the Shareholder(s) entitled under Section 2.1 to nominate
         such director whose death, disability, retirement, resignation or
         removal resulted in such vacancy, may, subject to the provisions of
         Section 2.1, nominate another individual (the "Nominee") to fill such
         vacancy and serve as a director of the Company;



                                       17
<PAGE>   22

                  (b)      subject to Section 2.1, each Shareholder then
         entitled to vote for the election of the Nominee as a director of the
         Company agrees that it will vote its shares of Common Stock, or execute
         a written consent, as the case may be, in order to ensure that the
         Nominee be elected to the Board; and

                  (c)      in the case of removal of either of the Primary
         Executives from the Board, the other Primary Executive, if he is still
         a member of the Board, shall be entitled to nominate an individual to
         fill the resulting vacancy, and the provisions of Section 2.3(b) shall
         apply to the election of such nominee.

                  Section 2.4 ACTION BY THE BOARD. (a) A quorum of the Board
shall consist initially of three directors; provided that THL shall have the
right, subject to applicable law or regulation, in its sole discretion, until
such time as THL owns less than 25% of its Initial Ownership of shares of Common
Stock, to increase or decrease the number of directors necessary to constitute a
quorum.

                           (b)      All actions of the Board shall require the 
affirmative vote of at least a majority of the directors at a duly convened
meeting of the Board at which a quorum is present or the unanimous written
consent of the Board; provided that, in the event there is a vacancy on the
Board and an individual has been nominated to fill such vacancy, the first order
of business shall be to fill such vacancy.

                  Section 2.5 CONFLICTING CHARTER OR BYLAW PROVISION. Each
Shareholder shall vote its shares of Common Stock, and shall take all other
actions reasonably necessary, to ensure that the Company's certificate of
incorporation and bylaws (copies of which are attached 




                                       18
<PAGE>   23

hereto as Exhibits A and B) facilitate and do not at any time conflict with any
provision of this Agreement.

                                   ARTICLE III

                            RESTRICTIONS ON TRANSFER

                  Section 3.1 GENERAL. (a) Each Equity Investor understands and
agrees that the shares of Common Stock purchased pursuant to the Subscription
Agreement and the Equity Warrants received pursuant to the Equity Warrant
Acquisition Agreement have not been registered under the Securities Act and are
restricted securities. Each Shareholder agrees that it will not, directly or
indirectly, sell, assign, transfer, grant a participation in, pledge or
otherwise dispose of ("Transfer") any Shares or Equity Warrants (or solicit any
offers to buy or otherwise acquire, or take a pledge of any Shares or Equity
Warrants) except in compliance with the Securities Act and the terms and
conditions of this Agreement.

                           (b) Any attempt by any Shareholder to Transfer any
Shares or Equity Warrants not in compliance with this Agreement shall be null
and void and the Company shall not, and shall cause any transfer agent not to,
give any effect in the Company's stock records to such attempted Transfer.

                           (c) Notwithstanding anything herein to the contrary,
except as may be otherwise set forth in the applicable instrument, Derivatives
(other than the Equity Warrants) shall be transferable only by will, law of
descent or distribution or pursuant to Section 4.2 hereof.

                  Section 3.2 LEGENDS. (a) In addition to any other legend that
may be required, each certificate for 



                                       19
<PAGE>   24

Shares that is issued to any Shareholder shall bear a legend in substantially
the following form:

                  "THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES
ACT OF 1933, AS AMENDED, OR ANY STATE SECURITIES LAWS AND MAY NOT BE OFFERED OR
SOLD EXCEPT IN COMPLIANCE THEREWITH. THIS SECURITY IS ALSO SUBJECT TO ADDITIONAL
LIMITATIONS OR RESTRICTIONS ON TRANSFER AS SET FORTH IN THE INVESTORS' AGREEMENT
DATED AS OF JANUARY 21, 1998, COPIES OF WHICH MAY BE OBTAINED UPON REQUEST FROM
FISHER SCIENTIFIC INTERNATIONAL INC. OR ANY SUCCESSOR THERETO."

                           (b) If any Shares shall cease to be Registrable
Securities under clause (i) or clause (ii) of the definition thereof, the
Company shall, upon the written request of the holder thereof, issue to such
holder a new certificate evidencing such Shares without the first sentence of
the legend required by Section 3.2(a) endorsed thereon. If any Shares cease to
be subject to any and all limitations or restrictions on Transfer set forth in
this Agreement, the Company shall, upon the written request of the holder
thereof, issue to such holder a new certificate evidencing such Shares without
the second sentence of the legend required by Section 3.2(a) endorsed thereon.

                  Section 3.3 PERMITTED TRANSFEREES; TRANSFERS BY THL ENTITIES;
EXCHANGES BY THL ENTITIES. Notwithstanding anything in this Agreement to the
contrary, (a) any Non-THL Shareholder may at any time Transfer any or all of its
Shares or Equity Warrants to one or more of its Permitted Transferees so long as
(i) such Permitted Transferee shall have agreed in writing to be bound by the
terms of this Agreement pursuant to Section 7.3 and (ii) the Transfer to such
Permitted Transferee is not in violation of applicable federal or state
securities laws and (b) any THL Entity may at any 



                                       20
<PAGE>   25

time Transfer any or all of its Shares or Equity Warrants to any third party
(including THL Designated Transferees) so long as (i) the Transfer is in
compliance with Section 4.1 hereof, (ii) if the transferee is to be treated as a
THL Designated Transferee, such transferee shall have agreed in writing to be
bound by the terms of this Agreement pursuant to Section 7.3 and (iii) the
Transfer is not in violation of applicable federal or state securities laws. Any
THL Entity may at any time exchange (a "THL Exchange") with the Company any or
all of its voting Equity Securities on a share-for-share basis for shares of an
equivalent class of non-voting Equity Securities of the Company, which
non-voting Equity Securities shall have substantially the rights, preferences
and limitations as set forth in the form of certificate of designation attached
hereto as Exhibit C. The Company agrees to take all such actions, subject to
Applicable Law, as are reasonably requested by any THL Entity to effectuate a
THL Exchange.

                  Section 3.4 RESTRICTIONS ON TRANSFERS BY INSTITUTIONAL
SHAREHOLDERS. Except as provided in Section 3.3, each Institutional Shareholder
and each Permitted Transferee of such Institutional Shareholder may Transfer its
Shares and Equity Warrants only as follows:

                           (i)      in a Transfer made in compliance with 
         Section 4.1 or 4.2;

                           (ii)     in a Public Offering in connection with the 
         exercise of its rights under Article 5 hereof;

                           (iii)    following the earlier to occur of (A) the
         date on which the Percentage Ownership of such Institutional
         Shareholder and its Permitted Transferees is less than 25% of its
         Initial 




                                       21

         Ownership of shares of Common Stock and (B) the seventh anniversary of
         the Closing Date, to any Person other than any Adverse Person; or

                           (iv)     in a Transfer made after an Initial Public
         Offering in compliance with Rule 144 under the Securities Act;
         provided, however, notwithstanding the foregoing, the Institutional
         Shareholder may not Transfer an aggregate number of Shares of such
         class of Equity Securities that, together with all prior Transfers of
         such class by such Institutional Shareholder and its Permitted
         Transferees pursuant to one or more Rule 144 Transfers, represents more
         than (A) the aggregate number of Shares of such class Transferred by
         the THL Entities and their THL Designated Transferees (other than, in
         either case, to THL Designated Transferees) MULTIPLIED BY (B) such
         Institutional Shareholders' Initial Proportionate Equity Interest of
         such class; provided, further, that, for purposes of this subsection
         (iv), the Equity Warrants shall be treated as part of the class of
         shares of Common Stock and the calculations described herein shall
         include the number of shares of Common Stock issuable upon exercise of
         such Equity Warrants. The "Initial Proportionate Equity Interest" of a
         party is such party's Initial Ownership of such class divided by the
         Initial Ownership of THL of such class.

                  Section 3III.5 RESTRICTIONS ON TRANSFERS BY MANAGEMENT
SHAREHOLDERS. (a) Except as provided in Section 3.3, each Management Shareholder
and each Permitted Transferee of such Management Shareholder may Transfer its
Shares only as follows or as set forth in Section 3.5(b):



                                       22
<PAGE>   27

                           (i)      in a Transfer made in compliance with 
         Section 4.1 or 4.2;

                           (ii)     in a Public Offering in connection with the 
         exercise of its rights under Article 5 hereof;

                           (iii)    in a Transfer made after an Initial Public
         Offering in compliance with Rule 144 under the Securities Act;
         provided, however, notwithstanding the foregoing, the Management
         Shareholder may not Transfer an aggregate number of Shares of any class
         of Equity Securities that, together with all prior Transfers of such
         class by such Management Shareholder and its Permitted Transferees
         pursuant to one or more Rule 144 Transfers, represents more than (A)
         the aggregate number of Shares of such class Transferred by the THL
         Entities and their THL Designated Transferees (other than, in either
         case, to THL Designated Transferees) MULTIPLIED BY (B) such Management
         Shareholders' Initial Proportionate Equity Interest of such class;

                           (iv)     following the tenth anniversary of the
         Closing Date to any Third Party other than an Adverse Person; or

                           (v)      subject to Section 3.6, a Transfer by a
         Management Shareholder to another Management Shareholder (a "Management
         Transfer").

                           (b)      Each Management Shareholder and each 
Permitted Transferee of such Management Shareholder may Transfer its Shares to
any Person other than an Adverse Person upon the occurrence of a Qualifying
Public Offering.

                  Section 3.6 COMPANY RIGHT OF FIRST REFUSAL. (a) If a
Management Shareholder (an "Offeror") desires to Transfer Shares to another
Management Shareholder pursuant to the provisions of Section 3.5(a)(v):

                  (i) such Offeror shall give notice of such offer (the
         "Transfer Notice") to the Company. The Transfer Notice shall state the
         terms and conditions of such offer, including the name of the
         prospective purchaser, the proposed purchase price per share of such
         Shares (the "Offer Price"), payment terms (including a description of
         any proposed non-cash consideration), the type of disposition and the
         number of such Shares to be transferred ("Offered Shares"). The
         Transfer Notice shall further state that the Company may acquire, in
         accordance with the provisions of this Agreement, any of the Offered
         Shares for the price and upon the other terms and conditions, including
         deferred payment (if applicable), set forth therein.

                  (ii) For a period of ten Business Days after receipt of the
         Transfer Notice (the "Option Period"), the Company may, by notice in
         writing to the Offeror delivering such Transfer Notice, elect in
         writing to purchase all, but not less than all, of the Offered Shares
         at the Offer Price. The closing of the purchase of Shares pursuant to
         Section 3.5, shall take place at the principal office of the Company on
         the tenth day after the expiration of the Option Period. At such
         Closing, the Company shall deliver to the Offeror, against delivery of
         certificates duly endorsed and stock powers representing the Shares
         being acquired by the Company, the Offer Price, on the same terms as
         set forth in the Transfer Notice (including any non-cash consideration
         described therein), payable in respect of the Shares being purchased by
         the Company. All 



                                       24
<PAGE>   29

         of the foregoing deliveries will be deemed to be made simultaneously,
         and none shall be deemed completed until all have been completed.

         (b) The provisions of Section 3.6(a) shall not apply to a Management
Shareholder (other than a Primary Executive) if such Management Shareholder
Transfers Shares aggregating, with all other prior Transfers of Shares by such
Management Shareholder, an amount less than 25% of such Management Shareholder's
Initial Ownership.

                  Section 3.7 NOTIFICATIONS REGARDING TRANSFERS. To the extent
that either an Institutional Shareholder proposes a Transfer pursuant to Section
3.4(iv) or a Management Shareholder proposes a Transfer pursuant to Section
3.5(a)(iii), such Shareholder shall provide notice to THL at least five Business
Days prior to the proposed Transfer Date of the number of Shares proposed to be
Transferred. Not less than two Business Days prior to the proposed Transfer
Date, THL shall notify such Shareholder of whether the Transfer is believed to
be permitted based on the formulas set forth in Section 3.4(iv) or 3.5(a)(iii),
as applicable.



                                   ARTICLE IV

             TAG-ALONG RIGHTS; DRAG-ALONG RIGHTS; PREEMPTIVE RIGHTS

                  Section 4.1 RIGHTS TO PARTICIPATE IN TRANSFER. (a) If the THL
Entities propose to Transfer (a "Tag-Along Sale") shares of a class of Equity
Securities, other than Transfers of shares of such class (i) in a Public
Offering pursuant to the exercise of their rights 



                                       25
<PAGE>   30

under Article 5, (ii) to any THL Designated Transferee, (iii) up to the
Threshold Percentage or (iv) in a THL Exchange, the Non-THL Shareholders may, at
their option, elect to exercise their rights under this Section 4.1 (each such
Shareholder, a "Tag-Along Person"); provided, however, that the exception set
forth in clause (iii) shall not apply to the Primary Executives. The "Threshold
Percentage" shall equal 5% in the aggregate of the THL Entities' Initial
Ownership of such class of Equity Securities.

                           (b) In the event of a proposed Transfer in accordance
with paragraph (a) above, THL shall provide each Non-THL Shareholder written
notice of the terms and conditions of such proposed Transfer ("Tag-Along
Notice") at least 10 days prior to such proposed Transfer and offer each
Tag-Along Person the opportunity to participate in such sale. The Tag-Along
Notice shall identify the number of shares of such class of Equity Securities to
be sold in the Tag-Along Sale ("Tag-Along Offer"), the price at which the
Transfer is proposed to be made, and all other material terms and conditions of
the Tag-Along Offer, including the form of the proposed agreement, if any. From
the date of the Tag-Along Notice, each Tag-Along Person shall have the right (a
"Tag-Along Right"), exercisable by written notice ("Tag-Along Response Notice")
given to THL within 5 Business Days (the "Tag-Along Notice Period"), to request
that THL include in the proposed Transfer the number of shares of such class of
Equity Securities held by such Tag-Along Person as is specified in such notice;
provided that if the aggregate number of shares of such class of Equity
Securities proposed to be sold by the THL Entities and all Tag-Along Persons in
such transaction exceeds the number of shares of such class of Equity Securities
which can be sold on the terms and conditions set forth in the Tag-Along Notice,
then only the Tag-Along Portion of shares of the THL Entities and each Tag-Along
Person 




                                       26
<PAGE>   31

shall be sold pursuant to the Tag-Along Offer. "Tag-Along Portion" means,
with respect to any class of Equity Securities, the number of shares of such
class held (or, without duplication, that such Shareholder has the right to
acquire from any Person) by the Tag-Along Person or THL, as the case may be,
multiplied by a fraction, the numerator of which is the maximum number of shares
of such class subject to the Tag-Along Offer and the denominator of which is the
aggregate number of shares of such class on a Fully Diluted basis owned by all
Shareholders. In the event the THL Entities shall propose to Transfer a number
of shares of such class in excess of the Threshold Percentage, the Tag-Along
Portion shall be calculated with respect to all of the shares proposed to be
Transferred by the THL Entities. To the extent that the Tag-Along Notice
provides that shares of Common Stock and Equity Warrants will be transferred (i)
the Equity Warrants and the Common Stock shall be treated as part of a single
class of Equity Securities and, if applicable, Equity Warrants are referred to
in this Section 4.1 as "shares" of such class, (ii) the calculations described
in this Section 4.1 with respect to such Tag-Along Notice shall include the
number of shares of Common Stock issuable upon exercise of such Equity Warrants
and (iii) the allocation between Equity Warrants and shares of Common Stock
subject to the Tag-Along Rights will be proportional to the allocation of the
number of Shares subject to the Tag-Along Notice as compared with the number of
Equity Warrants subject to the Tag-Along Notice.

                           (c) If the Tag-Along Persons exercise their Tag-Along
Rights hereunder, each Tag-Along Person shall deliver, together with its
Tag-Along Response Notice, to THL the certificate or certificates representing
the Shares of such Tag-Along Person to be included in the Transfer, together
with a limited power-of-attorney authorizing THL to Transfer such Shares 



                                       27
<PAGE>   32

on the terms set forth in the Tag-Along Notice. It is understood that to the
extent THL can do so without affecting the other terms on which the Tag-Along
Sale is proposed to be made, THL will seek to exclude from the terms of such
Tag-Along Sale any material restrictions on the ability, following such
Tag-Along Sale, of any Tag-Along Person to conduct its business in a manner
consistent with past practice. Delivery of such certificate or certificates
representing the shares to be Transferred and the limited power-of-attorney
authorizing THL to Transfer such shares shall constitute an irrevocable
acceptance of the Tag-Along Offer by such Tag-Along Persons. If, at the end of a
120 day period after such delivery, THL has not completed the Transfer of all
such shares on substantially the same terms and conditions set forth in the
Tag-Along Notice, THL shall return to each Tag-Along Person the limited
power-of-attorney (and all copies thereof) together with all certificates
representing the shares which such Tag-Along Person delivered for Transfer
pursuant to this Section 4.1.

                           (d) Concurrently with the consummation of the
Tag-Along Sale, THL shall notify the Tag-Along Persons thereof, shall remit to
the Tag-Along Persons the total consideration (by bank or certified check) for
the Shares of the Tag-Along Persons Transferred pursuant thereto, and shall,
promptly after the consummation of such Tag-Along Sale furnish such other
evidence of the completion and time of completion of such Transfer and the terms
thereof as may be reasonably requested by the Tag-Along Persons.

                           (e) If at the termination of the Tag-Along Notice
Period any Tag-Along Person shall not have elected to participate in the
Tag-Along Sale, such Tag-Along Person will be deemed to have waived its rights



                                       28
<PAGE>   33

under Section 4.1(a), with respect to the Transfer of its securities pursuant to
such Tag-Along Sale.

                           (f) If any Tag-Along Person declines to exercise its
Tag-Along Rights or elects to exercise its Tag-Along Rights with respect to less
than such Tag-Along Person's Tag-Along Portion, the THL Entities shall be
entitled to Transfer, pursuant to the Tag-Along Offer, a number of shares held
by the THL Entities equal to the number of shares constituting the portion of
such Tag-Along Person's Tag-Along Portion with respect to which Tag-Along Rights
were not exercised.

                           (g) THL may sell, on behalf of the THL Entities and
any Tag-Along Person who exercises the Tag-Along Rights pursuant to this Section
4.1, the shares subject to the Tag-Along Offer on the terms and conditions set
forth in the Tag-Along Notice within 120 days of the date on which Tag-Along
Rights shall have been waived, exercised or expire.

                  Section 4.2 RIGHT TO COMPEL PARTICIPATION IN CERTAIN
TRANSFERS. (a) If (i) the THL Entities propose to Transfer not less than 50% of
their Initial Ownership of Common Stock to a Third Party in a bona fide sale or
(ii) the THL Entities propose a Transfer in which the shares of Common Stock to
be Transferred by Shareholders constitute more than 50% of the outstanding
shares of Common Stock (a "Drag-Along Sale"), THL may at its option require all
Shareholders to sell all Equity Securities proposed to be sold therein
("Drag-Along Rights") then held by every Non-THL Shareholder, and (subject to
and at the closing of the Drag-Along Sale) to compel to exercise all, but not
less than all, of the Derivatives (whether then vested or unvested) held by
every Non-THL Shareholder and to sell all of the Shares received upon such
exercise to such Third Party, for the same 




                                       29
<PAGE>   34

consideration and otherwise on the same terms and conditions as the THL
Entities; provided, that any Non-THL Shareholder who holds Derivatives the
exercise price per share of which is greater than the per share price at which
the Shares are to be sold to the Third Party may, if required by THL to exercise
such Derivatives, in place of such exercise, submit to irrevocable cancellation
thereof without any liability for payment of any exercise price with respect
thereto; provided, further, that, upon such Drag-Along Sale, the Primary
Executives shall have the right, but not the obligation, to require the Equity
Investors to, at THL's option, either arrange for the purchase by a third party
or purchase directly all of the Shares held by such Primary Executive as a
condition to consummation of such Drag-Along Sale and, in which case the number
of shares to be sold by each Equity Investor will be reduced on a proportional
basis. The number of shares of each class of Equity Securities to be sold by
each Non-THL Shareholder will be the Drag-Along Portion of the shares of such
class that such Non-THL Shareholder owns. "Drag-Along Portion" means, with
respect to any Non-THL Shareholder and any class of Equity Securities, the
number of Shares of such class of Equity Securities beneficially owned by such
Non-THL Shareholder multiplied by a fraction, the numerator of which is the
number of shares of such class of Equity Securities proposed to be sold by the
THL Entities on behalf of the THL Entities and the Non-THL Shareholders (as
reduced by the number of shares of such class of Equity Securities to be sold by
the Primary Executives in excess of their pro rata interest) and the denominator
of which is the total number of shares of such class of Equity Securities
beneficially owned by the Shareholders. In the event the Drag-Along Sale is not
consummated with respect to any shares acquired upon exercise of Derivatives,
such Derivatives shall be deemed not to have been exercised or cancelled, as
applicable. To the extent the Drag-Along Sale relates to Derivatives, and THL
determines not to 



                                       30
<PAGE>   35

compel the exercise thereof, the Derivatives shall be treated as a separate
class of Equity Securities and, if applicable, Derivatives are referred to in
this Section 4.2 as "shares" of such class.

                           (b) THL shall provide written notice of such
Drag-Along Sale to the Non-THL Shareholders (a "Drag-Along Notice") not later
than the fifteenth day prior to the proposed Drag-Along Sale. The Drag-Along
Notice shall identify the Transferee, the number of shares of any class of
Equity Securities, the consideration for which a Transfer is proposed to be made
for each class of Equity Securities (the "Drag-Along Sale Price(s)") and all
other material terms and conditions of the Drag-Along Sale. Subject to Section
4.2(d), each Non-THL Shareholder shall be required to participate in the
Drag-Along Sale on the terms and conditions set forth in the Drag-Along Notice
and to tender all its Shares as set forth below. It is understood that to the
extent THL can do so without affecting the other terms on which the Drag-Along
Sale is proposed to be made, THL will seek to exclude from the terms of such
Drag-Along Sale any material restrictions on the ability, following such
Drag-Along Sale, of any Non-THL Shareholder to conduct its business in a manner
consistent with past practice. The price(s) payable in such Transfer shall be
the Drag-Along Sale Price(s). Not later than the tenth day following the date of
the Drag-Along Notice (the "Drag-Along Notice Period"), each of the Non-THL
Shareholders shall deliver to a representative of THL designated in the
Drag-Along Notice certificates representing all the Shares beneficially owned
and held by such Non-THL Shareholder, duly endorsed, (or evidence of title and
ownership of any Derivative which are subject to the Drag-Along Sale but which
are not exercised in connection therewith) together with all other documents
required to be executed in connection with such Drag-Along Sale, or 




                                       31
<PAGE>   36

if such delivery is not permitted by applicable law, an unconditional agreement
to deliver such shares pursuant to this Section 4.2 at the closing for such
Drag-Along Sale against delivery to such Non-THL Shareholder of the
consideration therefor. If a Non-THL Shareholder should fail to deliver such
certificates to THL, the Company shall cause the books and records of the
Company to show that such shares are bound by the provisions of this Section 4.2
and that such shares shall be Transferred to the purchaser of the shares
immediately upon surrender for Transfer by the holder thereof.

                           (c) The THL Entities shall have a period of 90 days
from the date of receipt of the Drag-Along Notice to consummate the Drag-Along
Sale on the terms and conditions set forth in such Drag-Along Sale Notice. If
the Drag-Along Sale shall not have been consummated during such period, THL
shall return to each of the Non-THL Shareholders all certificates or other
evidence of title and ownership representing shares that such Non-THL
Shareholder delivered for Transfer pursuant hereto, together with any documents
in the possession of THL executed by the Non-THL Shareholder in connection with
such proposed Transfer, and all the restrictions on Transfer contained in this
Agreement or otherwise applicable at such time with respect to shares owned by
the Non-THL Shareholders shall again be in effect.

                           (d) Concurrently with the consummation of the
Transfer of shares pursuant to this Section 4.2, THL shall give notice thereof
to all Shareholders, shall remit to each of the Shareholders who have
surrendered their certificates or other evidence of title and ownership the
total consideration (by bank or certified check) for the shares Transferred
pursuant hereto and shall furnish such other evidence of the completion and time
of completion of such Transfer and the terms thereof as may be reasonably
requested by such Shareholders.




                                       32
<PAGE>   37




                           (e) Notwithstanding any provision of this Agreement
to the contrary, in the event the terms on which a Drag-Along Sale is proposed
to be made shall include a provision which materially and adversely affects the
ability of any Non-THL Shareholder to compete in any line of business or
geographic area, such Non-THL Shareholder shall not be required to participate
in the Drag-Along Sale on the terms and conditions set forth in the Drag-Along
Notice. In the event any Shareholder shall elect, pursuant to the preceding
sentence, not to participate in the Drag-Along Sale, THL Entities and their THL
Designated Transferees shall have the right to purchase, and such Shareholder
shall be obligated to sell to the THL Entities and their THL Designated
Transferees such Shareholder's shares, at the Drag-Along Sale Price(s) and on
substantially the same terms (other than any such non-compete provision), not
later than immediately prior to the consummation of the Drag-Along Sale. Except
as provided above, in connection with any Drag-Along Sale, all Shareholders
shall be subject to (i) the same terms and conditions of sale and (ii) the same
indemnity, contribution, hold-back, escrow or similar obligations.

                  Section 4.3 PREEMPTIVE RIGHTS. (a) The Company shall provide
each Shareholder with a written notice (a "Preemptive Rights Notice") of any
proposed issuance by the Company of Equity Securities (other than the issuance
of Equity Securities in connection with a THL Exchange) at least 10 days prior
to the proposed issuance date. Such notice shall specify the price at which the
Equity Securities are to be issued and the other material terms of the issuance.

                           (i) In the event the Company shall issue any New
         Common Securities or New Preferred Securities (collectively, the "New
         Securities") to 




                                       33
<PAGE>   38

         any third party (including any Shareholder) prior to a Qualifying
         Public Offering, the THL Entities and each Management Shareholder shall
         be entitled to purchase, at the price and on the terms at which such
         New Securities are proposed to be issued and specified in such
         Preemptive Rights Notice, the THL Entities' or such Management
         Shareholder's Preemptive Rights Portion of such class of the New
         Securities proposed to be issued. "Preemptive Rights Portion" means,
         with respect to New Common Securities, the pro rata portion of New
         Common Securities proposed to be issued by the Company, which amount
         shall be based upon such Shareholder's Initial Ownership of shares of
         Common Stock as a percentage of the sum of the Initial Ownership of
         shares of Common Stock of (A) the THL Entities, (B) all Institutional
         Shareholders and (C) all Management Shareholders and, with respect to
         New Preferred Securities, the pro rata portion of New Preferred
         Securities proposed to be issued by the Company, which amount shall be
         based upon such Shareholder's Initial Ownership of shares of Preferred
         Stock as a percentage of the sum of the Initial Ownership of shares of
         Preferred Stock of (A) the THL Entities and (B) all Institutional
         Shareholders.

                  (ii) In the event that the Company shall issue any New
         Securities to any third party (including any Shareholder) following a
         Qualifying Public Offering, the THL Entities shall be entitled to
         purchase, at the price and on the terms at which such New Securities
         are proposed to be issued and specified in such Preemptive Rights
         Notice, the THL Entities' Preemptive Rights Portion of such class of
         the New Securities proposed to be issued.



                                       34
<PAGE>   39

                  (iii) In the event the THL Entities propose to purchase any
         New Securities from the Company pursuant to Section 4.3(a)(i) or (ii)
         or otherwise, the THL Entities may elect to purchase any or all of
         their Preemptive Rights Portion in the form of non-voting New
         Securities on the same terms and conditions as would have been
         available to purchase shares of voting New Securities.

                  (iv) In the event the THL Entities propose to purchase any New
         Securities from the Company pursuant to 4.3(a)(i) or (ii) or otherwise,
         (A) prior to a Qualifying Public Offering, each Institutional
         Shareholder, and (B) following a Qualifying Public Offering, each
         Non-THL Shareholder shall be entitled to purchase, at the price and on
         the terms at which the THL Entities propose to purchase such New
         Securities and specified in such Preemptive Rights Notice, such
         Shareholder's Preemptive Rights Portion of such class of the New
         Securities proposed to be issued in the transaction giving rise to the
         THL Entities' proposed purchase of New Securities; provided, however,
         such Shareholders shall not be entitled to purchase New Securities
         unless the THL Entities complete the purchase of New Securities in
         accordance with the Preemptive Rights Notice.

                  A Shareholder may exercise its rights under this Section 4.3
by delivering written notice of its election to purchase New Securities to the
Company, THL and each Non-THL Shareholder within five days of receipt of the
Preemptive Rights Notice. A delivery of such a written notice (which notice
shall specify the number of New Securities to be purchased by the Shareholder
submitting such notice) by such Shareholder shall constitute a binding agreement
of such Shareholder to purchase, subject to the purchase by THL of its portion


                                       35
<PAGE>   40

of such New Securities, at the price and on the terms specified in the
Preemptive Rights Notice, the number of New Securities specified in such
Shareholder's written notice.

                           (b) In the event any Non-THL Shareholder declines to
exercise its preemptive rights under this Section 4.3 or elects to exercise such
rights with respect to less than such Shareholder's Preemptive Rights Portion,
the THL Entities shall have the right to purchase, or any Non-THL Shareholder
designated by THL shall have the right to purchase, from the Company the number
of New Securities constituting the Preemptive Rights Portion with respect to
which such Non-THL Shareholder shall not have exercised its preemptive rights.

                           (c) In the case of any issuance of New Securities,
the Company shall have 90 days from the date of the Preemptive Rights Notice to
consummate the proposed issuance of any or all of such New Securities which the
Shareholders have not elected to purchase at the price and upon terms that are
not materially less favorable to the Company than those specified in the
Preemptive Rights Notice. At the consummation of such issuance, the Company
shall issue certificates representing the New Securities to be purchased by each
Shareholder exercising preemptive rights pursuant to this Section 4.3 registered
in the name of such Shareholder, against payment by such Shareholder of the
purchase price for such New Securities. If the Company proposes to issue New
Securities after such 90-day period, it shall again comply with the procedures
set forth in this Section.

                           (d) Notwithstanding the foregoing, no Shareholder
shall be entitled to purchase New Securities as contemplated by this Section 4.3
in connection with 



                                       36
<PAGE>   41

issuances of New Securities (i) to employees of the Company or any Subsidiary
pursuant to employee benefit plans or arrangements approved by the Board
(including upon the exercise of employee stock options), or (ii) in connection
with any bona fide, arm's-length restructuring or refinancing of outstanding
indebtedness (including convertible indebtedness) of the Company or any
Subsidiary. The Company shall not be under any obligation to consummate any
proposed issuance of New Securities, regardless of whether it shall have
delivered a Preemptive Rights Notice in respect of such proposed issuance.

                           (e) The Company will use its reasonable best efforts
to provide the Preemptive Rights Notice at least 15 Business Days prior to any
proposed issuance of New Securities. In the event it is impracticable to provide
the Preemptive Rights Notice at least 15 Business Days prior to such issuance,
any Shareholder may offer to finance or arrange to finance the purchase by any
other Shareholder of such other Shareholder's Preemptive Rights Portion and such
financing or arranging Shareholder shall be entitled to receive as compensation
for such services reasonable and customary fees and expenses. No Shareholder
shall be under any obligation to provide or arrange such financing for any other
Shareholder.

                  Section 4.4. CERTAIN OTHER PURCHASES OF EQUITY SECURITIES. In
the event, at any time after the date hereof and prior to the Trigger Date, the
THL Entities shall acquire any Equity Securities (other than Equity Securities
acquired in a THL Exchange) from any Person other than the Shareholders, THL
shall deliver, within five Business Days of the date of such acquisition, a
notice to each Equity Investor (a "Third Party Purchase Notice") specifying the
class of Equity Securities, the number of shares of such class acquired and the
weighted average of price per share paid by the THL Entities. 



                                       37
<PAGE>   42

Such Third Party Purchase Notice shall constitute an offer to each such
Shareholder to purchase such Shareholder's Third Party Purchase Portion of the
number of shares of such class acquired by the THL Entities. A Shareholder may
exercise its rights under this Section 4.4 by delivering written notice of its
election to purchase its Third Party Purchase Portion within ten days of receipt
of the Third Party Purchase Notice. A delivery of such written notice (which
shall specify the number of shares of such class of Equity Securities to be
purchased by the Shareholder submitting such notice) by such Shareholder shall
constitute a binding agreement of such Shareholder to purchase, at the price and
on the terms specified in the Third Party Purchase Notice, the number of shares
of a class of Equity Securities specified in such notice. At the consummation of
the Transfer of the shares of a class of Equity Securities purchased by the THL
Entities to any Shareholder that has exercised its right hereunder, the THL
Entities shall deliver to such Shareholder certificates or other evidence of
title and ownership representing the shares of such class of Equity Securities
to be purchased against payment by such Shareholder of the purchase price for
such shares of Equity Securities. "Third Party Purchase Portion" means, with
respect to any Shareholder at any time, the number of shares of the class of
Equity Securities purchased by the THL Entities in a transaction subject to
Section 4.4, multiplied by a fraction, the numerator of which is (i) the number
of shares of such class of Equity Securities on a Fully Diluted basis that such
Shareholder beneficially owns at such time, and the denominator of which is (ii)
the total number of shares of such class of Equity Securities on a Fully Diluted
basis beneficially owned at such time by all Equity Investors. To the extent the
Third Party Purchase Notice relates to Derivatives, such Derivatives shall be
treated as a separate class of Equity Securities and, if 



                                       38
<PAGE>   43

applicable, Derivatives are referred to in this Section 4.4 as "shares" of such
class.

                                    ARTICLE V

                               REGISTRATION RIGHTS

                  Section 5.1 DEMAND REGISTRATION. (a) If the Company shall
receive a written request by THL that the Company effect the registration under
the Securities Act of all or a portion of the THL Entities' Registrable
Securities, and specifying the intended method of disposition thereof, then the
Company shall promptly give written notice of such requested registration (a
"THL Demand Registration") at least five days prior to the anticipated filing
date of the registration statement relating to such THL Demand Registration to
the Non-THL Shareholders and thereupon will use its best efforts to effect, as
expeditiously as possible, the registration under the Securities Act of:

                           (i) the Registrable Securities of the THL Entities
         which the Company has been so requested to register; and

                           (ii) subject to the restrictions set forth in Section
         5.2, all other Registrable Securities of the same class as that to
         which THL's request relates for which an effective Piggyback
         Registration (as such term is defined in Section 5.2) request has been
         made;

provided, that subject to Section 5.1(d) hereof, the Company shall not be
obligated to effect more than six THL Demand Registrations. In no event will the
Company 



                                       39
<PAGE>   44

be required to effect more than one THL Demand Registration within any
four-month period.

                           (b) Promptly after the expiration of the 2-day period
referred to in Section 5.2(a) hereof, the Company will notify all the
Shareholders to be included in the THL Demand Registration (the "Holders") of
the other Holders and the number of Registrable Securities requested to be
included therein. THL may, at any time prior to the effective date of the
registration statement relating to such registration, revoke such request,
without liability to any of the other Holders, by providing a written notice to
the Company revoking such request, in which case such request, so revoked, shall
not be considered a THL Demand Registration.

                           (c) The Company will pay all Registration Expenses in
connection with any THL Demand Registration.

                           (d) A registration requested pursuant to this Section
5.1 shall not be deemed to have been effected (i) unless the registration
statement relating thereto (A) has become effective under the Securities Act and
(B) has remained effective for a period of at least 180 days (or such shorter
period in which all Registrable Securities of the Holders included in such
registration have actually been sold thereunder); provided, that if after any
registration statement requested pursuant to this Section 5.1 becomes effective
(x) such registration statement is interfered with by any stop order, injunction
or other order or requirement of the SEC or other governmental agency or court
and (y) less than 75% of the Registrable Securities included in such
registration statement have been sold thereunder, such registration statement
shall not be considered a THL Demand Registration, or (ii) if the Maximum
Offering Size (as defined below) is reduced in accordance with Section 5.1(e)
such that less than 66 2/3% of the Registrable 



                                       40
<PAGE>   45

Securities of the THL Entities sought to be included in such registration are
included.

                           (e) If a THL Demand Registration involves an
Underwritten Public Offering and the managing underwriter shall advise the
Company and THL that, in its view, (i) the number of shares of Registrable
Securities requested to be included in such registration (including any
securities which the Company proposes to be included which are not Registrable
Securities) or (ii) the inclusion of some or all of the shares of Registrable
Securities owned by the Holders, in any such case, exceeds the largest number of
shares which can be sold without having an adverse effect on such offering,
including the price at which such shares can be sold (the "Maximum Offering
Size"), the Company will include in such registration, in the priority listed
below, up to the Maximum Offering Size:

                           (A) first, all Registrable Securities requested by
         THL to be registered and all Registrable Securities requested to be
         included in such registration by any other Holder pursuant to an
         effective Piggyback Registration request (allocated, if necessary for
         the offering not to exceed the Maximum Offering Size, pro rata among
         the THL Entities and such Holders on the basis of the relative number
         of Registrable Securities held by such Shareholder); and

                           (B) second, any securities proposed to be registered
         by the Company.

PROVIDED, however, that in such case, any Holder may elect to withdraw such
Holder's Registrable Securities from the registration.




                                       41
<PAGE>   46




                           (f) Upon written notice to THL, the Company may
postpone effecting a registration pursuant to this Section 5.1 on one occasion
during any period of six consecutive months for a reasonable time specified in
the notice but not exceeding 90 days (which period may not be extended or
renewed), if (i) an investment banking firm of recognized national standing
shall advise the Company and THL in writing that effecting the registration
would materially and adversely affect an offering of securities of the Company
the preparation of which had then been commenced or (ii) the Company has a bona
fide business reason for determining that it is in possession of material
non-public information the disclosure of which during the period specified in
such notice the Company believes, in its reasonable judgment, would not be in
the best interests of the Company.

                           (g) After the Company has effected two Demand
Registrations pursuant to this Section 5.1 of Common Stock, the Institutional
Shareholders, upon request of such Institutional Shareholders owning a majority
of the Shares acquired by such Institutional Shareholders on the Closing Date,
may request that the Company register shares of Registrable Securities then
owned by such Institutional Shareholders (an "Institutional Shareholder Demand
Registration"). In no event will the Company be required to effect more than one
such Institutional Shareholder Demand Registration. The provisions of this
Article 5 shall apply, mutatis mutandis, to any such Institutional Shareholder
Demand Registration.

                           (h) After the Transfer of Shares of Common Stock
representing more than 20% of the Shares collectively owned by the Equity
Investors of the Initial Ownership on a Fully Diluted basis owned by such Equity
Investors, the Primary Executives may request that the Company register Shares
which are Registrable Securities 



                                       42
<PAGE>   47

then owned by them (a "Primary Executive Demand Registration"). In no event will
the Company be required to effect more than three such Primary Executive Demand
Registrations. The provisions of this Article 5 shall apply, mutatis mutandis,
to any such Primary Executive Demand Registration; provided, that,
notwithstanding anything to the contrary herein, (i) no Primary Executive Demand
Registrations may be made during the six month period following the Effective
Time or within six months after the effective date any other registration
statement (other than registration statement on From S-4 or S-8 or similar
form), and (ii) the Company must use its best efforts to effect such Primary
Executive Demand Registration as soon as practicable, but in no event later than
120 days following the date of the demand.

                  Section 5.2 PIGGYBACK REGISTRATION. (a) If the Company
proposes to register any Equity Securities under the Securities Act, whether or
not for sale for its own account (including pursuant to a Demand Registration),
in connection with a public offering (other than a public offering pursuant to a
registration statement filed in connection with a transaction of the type
described in Rule 145 of the Securities Act or for the purpose of issuing
securities pursuant to an employee benefit plan) it will each such time, subject
to the provisions of Section 5.2(b) hereof, give prompt written notice at least
five days prior to the anticipated filing date of the registration statement
relating to such registration to all Shareholders and their respective Permitted
Transferees (or, in the case of a Demand Registration to all Shareholders and
their Permitted Transferees other than the Shareholder making the demand), which
notice shall set forth such Shareholders' rights under this Section 5.2 and
shall offer all Shareholders the opportunity to include in such registration
statement such number of shares of Common 




                                       43
<PAGE>   48

Stock as each such Shareholder may request (a "Piggyback Registration"). Upon
the written request of any such Shareholder made within 2 days (one of which
shall be a Business Day) after the receipt of notice from the Company (which
request shall specify the number of Registrable Securities intended to be
disposed of by such Shareholder), the Company will use its reasonable best
efforts to effect the registration under the Securities Act of all Registrable
Securities which the Company has been so requested to register by such
Shareholders, to the extent requisite to permit the disposition of the
Registrable Securities so to be registered; provided, that (i) if such
registration involves an Underwritten Public Offering, all such Shareholders
requesting to be included in the Company's registration must sell their
Registrable Securities to the underwriters selected as provided in Section
5.4(f) on the same terms and conditions as apply to the Company or the other
selling Shareholder, as applicable, and (ii) if, at any time after giving
written notice of its intention to register on its own behalf any stock and
prior to the effective date of the registration statement filed in connection
with such registration, the Company shall determine for any reason not to
register such stock, the Company shall give written notice to all such
Shareholders and, thereupon, shall be relieved of its obligation to register any
Registrable Securities in connection with such registration. No registration
effected under this Section 5.2 on behalf of the Company shall relieve the
Company of its obligations to effect a Demand Registration, to the extent
required by Section 5.1 hereof. The Company will pay all Registration Expenses
in connection with each registration of Registrable Securities requested
pursuant to this Section 5.2.

                           (b) If a registration pursuant to this Section 5.2
involves an Underwritten Public Offering (other than in the case of an
Underwritten Public 



                                       44
<PAGE>   49

Offering resulting from a Demand Registration, in which case the provisions with
respect to priority of inclusion in such offering set forth in Section 5.1(e)
shall apply) and the managing underwriter advises the Company that, in its view,
the number of shares of Common Stock which the Company and the selling
Shareholders intend to include in such registration exceeds the Maximum Offering
Size, the Company will include in such registration, in the following priority,
up to the Maximum Offering Size:

                           (i) first, so much of the Equity Securities proposed
         to be registered for the account of the Company as would not cause the
         offering to exceed the Maximum Offering Size; and

                           (ii) second, all Registrable Securities requested to
         be included in such registration by any Shareholder pursuant to an
         effective Piggyback Registration request (allocated, if necessary for
         the offering not to exceed the Maximum Offering Size, pro rata among
         such Shareholders on the basis of the relative number of shares of
         Registrable Securities held by such Shareholder).

                  Section 5.3 HOLDBACK AGREEMENTS. With respect to each and
every firmly Underwritten Public Offering, each Shareholder (collectively with
all of its Affiliates which are Shareholders) owning Shares representing more
than 1% of the then outstanding Shares (including Shares which would be held
upon any conversion or exercise of rights) agrees, and their Permitted
Transferees will agree, not to offer or sell any Shares (except for Shares, if
any, sold in that Public Offering) during the period which commences on the 14th
day prior to the effective date of the applicable registration statement for a
public offering of Shares (except as part of such registration) and ends on the
earlier of: (i) 180 days after the effective date of the registration statement
or 




                                       45
<PAGE>   50

(ii) any such shorter period as the Company and the lead managing underwriter
of an Underwritten Public Offering agree.

                  Section 5.4 REGISTRATION PROCEDURES. Whenever Shareholders
request that any Registrable Securities be registered pursuant to Section 5.1 or
5.2 hereof, the Company will, subject to the provisions of such Sections, use
its best efforts, or reasonable best efforts, as the case maybe, to effect the
registration and the sale of such Registrable Securities in accordance with the
intended method of disposition thereof as quickly as practicable, and in any
event within 60 days of the date of demand and in connection with any such
request:

                  (a) The Company will as expeditiously as possible prepare and
         file with the SEC a registration statement on any form selected by
         counsel for the Company and which form shall be available for the sale
         of the Registrable Securities to be registered thereunder in accordance
         with the intended method of distribution thereof, and use its best
         efforts to cause such filed registration statement to become and remain
         effective for a period of not less than 180 days (or such shorter
         period in which all of the Registrable Securities of the Holders
         included in such registration statement shall have actually been sold
         thereunder).

                  (b) The Company will, if requested, prior to filing a
         registration statement or prospectus or any amendment or supplement
         thereto, furnish to each Shareholder and each underwriter, if any, of
         the Registrable Securities covered by such registration statement
         copies of such registration statement as proposed to be filed, and
         thereafter the Company will furnish to such Shareholder and
         underwriter, if any, such number of copies of such registration
         

                                       46
<PAGE>   51


         statement, each amendment and supplement thereto (in each case
         including all exhibits thereto and documents incorporated by reference
         therein), the prospectus included in such registration statement
         (including each preliminary prospectus) and such other documents as
         such Shareholder or underwriter may reasonably request in order to
         facilitate the disposition of the Registrable Securities owned by such
         Shareholder. Each Shareholder shall have the right to request that the
         Company modify any information contained in such registration
         statement, amendment and supplement thereto pertaining to such
         Shareholder and the Company shall use its reasonable best efforts to
         comply with such request; provided, however, that the Company shall not
         have any obligation to so modify any information if so doing would
         cause the prospectus to contain an untrue statement of a material fact
         or omit to state any material fact required to be stated therein or
         necessary to make the statements therein not misleading.

                  (c) After the filing of the registration statement, the
         Company will (i) cause the related prospectus to be supplemented by any
         required prospectus supplement, and as so supplemented to be filed
         pursuant to Rule 424 under the Securities Act, (ii) comply with the
         provisions of the Securities Act with respect to the disposition of all
         Registrable Securities covered by such registration statement during
         the applicable period in accordance with the intended methods of
         disposition by the sellers thereof set forth in such registration
         statement or supplement to such prospectus and (iii) promptly notify
         each Shareholder holding Registrable Securities covered by such
         registration statement of any stop order issued or threatened by the
         SEC or any state securities commission under state blue sky 



                                       47
<PAGE>   52

         laws and take all reasonable actions required to prevent the entry of
         such stop order or to remove it if entered.

                  (d) The Company will use its best efforts to (i) register or
         qualify the Registrable Securities covered by such registration
         statement under such other securities or blue sky laws of such
         jurisdictions in the United States as the Managing Underwriter or any
         Shareholder or Shareholders holding such Registrable Securities
         reasonably (in light of such Shareholder's intended plan of
         distribution) requests and (ii) cause such Registrable Securities to be
         registered with or approved by such other governmental agencies or
         authorities as may be necessary by virtue of the business and
         operations of the Company and do any and all other acts and things that
         may be reasonably necessary or advisable to enable such Shareholder to
         consummate the disposition of the Registrable Securities owned by such
         Shareholder; provided, however, 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 paragraph (d),
         (B) subject itself to taxation in any such jurisdiction or (C) consent
         to general service of process in any such jurisdiction.

                  (e) The Company will immediately notify each Shareholder
         holding such Registrable Securities covered by such registration
         statement, at any time when a prospectus relating thereto is required
         to be delivered under the Securities Act, of the occurrence of an event
         requiring the preparation of a supplement or amendment to such
         prospectus so that, as thereafter delivered to the purchasers of such
         Registrable Securities, such prospectus will 




                                       48
<PAGE>   53

         not contain an untrue statement of a material fact or omit to state any
         material fact required to be stated therein or necessary to make the
         statements therein not misleading and promptly prepare and make
         available to each such Shareholder and file with the SEC any such
         supplement or amendment.

                  (f) In connection with (i) (A) any THL Demand Registration or
         (B) any registration by the Company of Registrable Securities, the
         Company shall appoint the underwriter or underwriters chosen by THL and
         (ii) (A) any Institutional Shareholder Demand Registration or (B) any
         Primary Executive Demand Registration, the Company shall appoint the
         underwriter or underwriters chosen by Shareholders holding the majority
         of the Registrable Securities to be registered; provided, that the
         underwriter or underwriters identified in accordance with clauses
         (ii)(A) and (ii)(B) shall be reasonably acceptable to the Company. The
         Company will enter into customary agreements (including an underwriting
         agreement in customary form) and take such other actions as are
         reasonably required in order to expedite or facilitate the disposition
         of such Registrable Securities, including the engagement of a
         "qualified independent underwriter" in connection with the
         qualification of the underwriting arrangements with the NASD.

                  (g) Upon execution of confidentiality agreements in form and
         substance reasonably satisfactory to the Company, the Company will make
         available for inspection by any Shareholder and any underwriter
         participating in any disposition pursuant to a registration statement
         being filed by the Company pursuant to this Section 5.4 and any
         attorney, accountant or other professional retained by any such
         Shareholder or underwriter 




                                       49
<PAGE>   54

         (collectively, the "Inspectors"), all financial and other records,
         pertinent corporate documents and properties of the Company
         (collectively, the "Records") as shall be reasonably requested by any
         such Person, and cause the Company's officers, directors and employees
         to supply all information reasonably requested by any Inspectors in
         connection with such registration statement.

                  (h) The Company will furnish to each such Shareholder and to
         each such underwriter, if any, a signed counterpart, addressed to such
         underwriter and the participating Shareholders, of (i) an opinion or
         opinions of counsel to the Company and (ii) a comfort letter or comfort
         letters from the Company's independent public accountants, each in
         customary form and covering such matters of the type customarily
         covered by opinions or comfort letters, as the case may be, as a
         majority of such Shareholders or the managing underwriter therefor
         reasonably requests.

                  (i) The Company will otherwise use its best efforts to comply
         with all applicable rules and regulations of the SEC and the relevant
         state blue sky commissions, and make available to its securityholders,
         as soon as reasonably practicable, an earnings statement covering a
         period of 12 months, beginning within three months after the effective
         date of the registration statement, which earnings statement shall
         satisfy the provisions of Section 11(a) of the Securities Act.

                  (j) The Company may require each such Shareholder to promptly
         furnish in writing to the Company information regarding the
         distribution of the Registrable Securities as the Company may from time
         to time reasonably request and such other 




                                       50
<PAGE>   55

         information as may be legally required in connection with such
         registration.

                  (k) Each such Shareholder agrees that, upon receipt of any
         notice from the Company of the happening of any event of the kind
         described in Section 5.4(e) hereof, such Shareholder will forthwith
         discontinue disposition of Registrable Securities pursuant to the
         registration statement covering such Registrable Securities until such
         Shareholder's receipt of the copies of the supplemented or amended
         prospectus contemplated by Section 5.4(e) hereof, and, if so directed
         by the Company, such Shareholder will deliver to the Company all
         copies, other than any permanent file copies then in such Shareholder's
         possession, of the most recent prospectus covering such Registrable
         Securities at the time of receipt of such notice. In the event that the
         Company shall give such notice, the Company shall extend the period
         during which such registration statement shall be maintained effective
         (including the period referred to in Section 5.4(a) hereof) by the
         number of days during the period from and including the date of the
         giving of notice pursuant to Section 5.4(e) hereof to the date when the
         Company shall make available to such Shareholder a prospectus
         supplemented or amended to conform with the requirements of Section
         5.4(e) hereof.

                  (l) The Company will use its best efforts to list such
         Registrable Securities on any securities exchange on which the Common
         Stock is then listed or on NASDAQ if the Common Stock is then quoted on
         NASDAQ not later than the effective date of such registration
         statement.

                  Section 5.5 INDEMNIFICATION BY THE COMPANY. The Company agrees
to indemnify and hold harmless each Shareholder holding Registrable Securities
covered by a registration statement, its officers, directors, employees,
partners and agents, and each Person, if any, who controls such Shareholder
within the meaning of Section 15 of the Securities Act or Section 20 of the
Exchange Act (and officers, directors, employees, partners and agents of such
controlling Persons) from and against any and all losses, claims, damages, joint
or several liabilities or expenses (including reasonable attorneys' fees and
expenses and reasonable costs of investigation) caused by any untrue statement
or alleged untrue statement of a material fact contained in any registration
statement or prospectus relating to the Registrable Securities (as amended or
supplemented if the Company shall have furnished any amendments or supplements
thereto) or any preliminary prospectus, or caused by 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, except insofar as such
losses, claims, damages or liabilities are caused by any such untrue statement
or omission or alleged untrue statement or omission so made in strict conformity
with information furnished in writing to the Company by such Shareholder or on
such Shareholder's behalf expressly for use therein; provided that with respect
to any untrue statement or omission or alleged untrue statement or omission made
in any preliminary prospectus, or in any final prospectus, as the case may be,
the indemnity agreement contained in this paragraph shall not apply to the
extent that any such loss, claim, damage, liability or expense results from the
fact that a current copy of the final prospectus (or, in the case of a final
prospectus, the final prospectus as amended or supplemented) was not sent or
given to the Person asserting any such loss, claim, damage, liability or expense
at or prior to the written 




                                       52
<PAGE>   57

confirmation of the sale of the Registrable Securities concerned to such Person
if it is determined that the Company has provided such current copy of such
final prospectus (or such amended or supplemented prospectus, as the case may
be) to such Shareholder in a timely manner prior to such sale and it was the
responsibility of such Shareholder under the Securities Act to provide such
Person with a current copy of the prospectus (or such amended or supplemented
prospectus, as the case may be) and such current copy of the final prospectus
(or such amended or supplemented prospectus, as the case may be) would have
cured the defect giving rise to such loss, claim, damage, liability or expense.
The Company also agrees to indemnify any underwriters of the Registrable
Securities, their officers and directors and each person who controls such
underwriters on substantially the same basis as that of the indemnification of
the Shareholders provided in this Section 5.5.

                  Section 5.6 INDEMNIFICATION BY PARTICIPATING SHAREHOLDERS.
Each Shareholder holding Registrable Securities included in any registration
statement agrees, severally but not jointly, to indemnify and hold harmless the
Company, its officers, directors and agents and each Person (other than such
Shareholder), if any, who controls the Company within the meaning of either
Section 15 of the Securities Act or Section 20 of the Exchange Act to the same
extent as the foregoing indemnity from the Company to such Shareholder, but only
(i) with respect to information furnished in writing by such Shareholder or on
such Shareholder's behalf expressly for use in any registration statement or
prospectus relating to the Registrable Securities, or any amendment or
supplement thereto, or any preliminary prospectus or (ii) to the extent that any
loss, claim, damage, liability or expense described in Section 5.5 results from
the fact that a current copy of the final prospectus (or, in the case of a
prospectus, the prospectus as amended or 




                                       53
<PAGE>   58

supplemented) was not sent or given to the Person asserting any such loss,
claim, damage, liability or expense at or prior to the time of the written
confirmation of the sale of the Registrable Securities concerning such Person if
it is determined that it was the responsibility of such Shareholder to provide
such Person with a current copy of the final prospectus (or such amended or
supplemented prospectus, as the case may be) and such current copy of the final
prospectus (or such amended or supplemented prospectus, as the case may be)
would have cured the defect giving rise to such loss, claim, damage, liability
or expense. Each such Shareholder shall be prepared, if required by the
underwriting agreement, to indemnify and hold harmless underwriters of the
Registrable Securities, their officers and directors and each person who
controls such underwriters on substantially the same basis as that of the
indemnification of the Company provided in this Section 5.6. As a condition to
including Registrable Securities in any registration statement filed in
accordance with Article 5 hereof, the Company may require that it shall have
received an undertaking reasonably satisfactory to it from any underwriter to
indemnify and hold it harmless to the extent customarily provided by
underwriters with respect to similar securities.

                  No Shareholder shall be liable under Section 5.6 for any
damage thereunder in excess of the net proceeds realized by such Shareholder in
the sale of the Registrable Securities of such Shareholder.

                  Section 5.7 CONDUCT OF INDEMNIFICATION PROCEEDINGS. In case
any proceeding (including any governmental investigation) shall be instituted
involving any Person in respect of which indemnity may be sought pursuant to
this Article 5, such Person (an "Indemnified Party") shall promptly notify the
Person against whom such indemnity may be sought (the "Indemnifying Party") in
writing and the Indemnifying Party shall assume the 



                                       54
<PAGE>   59

defense thereof, including the employment of counsel reasonably satisfactory to
such Indemnified Party, and shall assume the payment of all fees and expenses;
provided that the failure of any Indemnified Party so to notify the Indemnifying
Party shall not relieve the Indemnifying Party of its obligations hereunder
except to the extent that the Indemnifying Party is materially prejudiced by
such failure to notify. In any such proceeding, any Indemnified Party shall have
the right to retain its own counsel, but the fees and expenses of such counsel
shall be at the expense of such Indemnified Party unless (i) the Indemnifying
Party and the Indemnified Party shall have mutually agreed to the retention of
such counsel or (ii) in the reasonable judgment of such Indemnified Party
representation of both parties by the same counsel would be inappropriate due to
actual or potential differing interests between them. It is understood that the
Indemnifying Party shall not, in connection with any proceeding or related
proceedings in the same jurisdiction, be liable for the reasonable fees and
expenses of more than one separate firm of attorneys (in addition to any local
counsel) at any time for all such Indemnified Parties, and that all such fees
and expenses shall be reimbursed as they are incurred. In the case of any such
separate firm for the Indemnified Parties, such firm shall be designated in
writing by the Indemnified Parties. The Indemnifying Party shall not be liable
for any settlement of any proceeding effected without its written consent, but
if settled with such consent, or if there be a final judgment for the plaintiff,
the Indemnifying Party shall indemnify and hold harmless such Indemnified
Parties from and against any and all losses, claims, damages, liabilities and
expenses or liability (to the extent stated above) by reason of such settlement
or judgment. No Indemnifying Party shall, without the prior written consent of
the Indemnified Party, effect any settlement of any pending or threatened
proceeding in respect of which any 




                                       55
<PAGE>   60

Indemnified Party is or could have been a party and indemnity could have been
sought hereunder by such Indemnified Party, unless such settlement includes an
unconditional release of such Indemnified Party from all liability arising out
of such proceeding.

                  Section 5.8 CONTRIBUTION. If the indemnification provided for
in this Article 5 is held by a court of competent jurisdiction to be unavailable
to the Indemnified Parties in respect of any losses, claims, damages or
liabilities referred to herein, then each such Indemnifying Party, in lieu of
indemnifying such Indemnified Party, shall contribute to the amount paid or
payable by such Indemnified Party as a result of such losses, claims, damages or
liabilities (i) as between the Company and the Shareholders holding Registrable
Securities covered by a registration statement and their related Indemnified
Parties on the one hand and the underwriters and their related Indemnified
Parties on the other, in such proportion as is appropriate to reflect the
relative benefits received by the Company and such Shareholders on the one hand
and the underwriters on the other, from the offering of the Shareholders'
Registrable Securities, or if such allocation is not permitted by applicable
law, in such proportion as is appropriate to reflect not only the relative
benefits but also the relative fault of the Company and such Shareholders on the
one hand and of such underwriters on the other in connection with the statements
or omissions which resulted in such losses, claims, damages or liabilities, as
well as any other relevant equitable considerations and (ii) as between the
Company and their related Indemnified Parties on the one hand and each such
Shareholder and their related Indemnified Parties on the other, in such
proportion as is appropriate to reflect the relative fault of the Company and of
each such Shareholder in connection with such statements or omissions, as well
as any other relevant equitable 






                                       56
<PAGE>   61

considerations. The relative benefits received by the Company and such
Shareholders on the one hand and such underwriters on the other shall be deemed
to be in the same proportion as the total proceeds from the offering (net of
underwriting discounts and commissions but before deducting expenses) received
by the Company and such Shareholders bear to the total underwriting discounts
and commissions received by such underwriters, in each case as set forth in the
table on the cover page of the prospectus. The relative fault of the Company and
such Shareholders on the one hand and of such underwriters on the other 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 the Company and such
Shareholders or by such underwriters. The relative fault of the Company on the
one hand and of each such Shareholder on the other 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 party, and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission.

                  The Company and the Shareholders agree that it would not be
just and equitable if contribution pursuant to this Section 5.8 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 immediately preceding
paragraph. The amount paid or payable by an Indemnified Party as a result of the
losses, claims, damages or liabilities referred to in the immediately preceding
paragraph shall be deemed to include, subject to the limitations set forth
above, any legal or other expenses reasonably incurred by such Indemnified Party
in connection with 




                                       57
<PAGE>   62

investigating or defending any such action or claim. Notwithstanding the
provisions of this Section 5.8 no underwriter shall be required to contribute
any amount in excess of the underwriting discount applicable to securities
purchased by such underwriter in such offering, less the aggregate amount of any
damages which such underwriter has otherwise been required to pay by reason of
such untrue or alleged untrue statement or omission or alleged omission, and no
Shareholder shall be required to contribute any amount in excess of the amount
by which the net proceeds realized on the sale of the Registrable Securities of
such Shareholder exceeds the amount of any damages which such Shareholder has
otherwise been required to pay by reason of such untrue or alleged untrue
statement or omission or alleged omission. No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation. Each Shareholder's obligation to contribute
pursuant to this Section 5.8 is several in the proportion that the proceeds of
the offering received by such Shareholder bears to the total proceeds of the
offering received by all such Shareholders and not joint.

                  Section 5.9 PARTICIPATION IN PUBLIC OFFERING. No Person may
participate in any Underwritten Public Offering hereunder unless such Person (a)
agrees to sell such Person's securities on the basis provided in any
underwriting arrangements approved by the Persons entitled hereunder to approve
such arrangements and (b) completes and executes all questionnaires, powers of
attorney, indemnities, underwriting agreements and other documents reasonably
required under the terms of such underwriting arrangements and the provisions of
this Agreement in respect of registration rights.

                  Section 5.10 COOPERATION BY THE COMPANY. In the event any
Shareholder shall Transfer any Registrable Securities pursuant to Rule 144A
under the Securities Act, the Company shall cooperate, to the extent
commercially reasonable, with such Shareholder and shall provide to such
Shareholder such information as such Shareholder shall reasonably request.

                  Section 5.11 NO TRANSFER OF REGISTRATION RIGHTS. None of the
rights of Shareholders under this Article 5 shall be assignable by any
Shareholder to any Person acquiring securities of such Shareholder in any Public
Offering or pursuant to Rule 144A of the Securities Act.

                                   ARTICLE VI

                        CERTAIN COVENANTS AND AGREEMENTS

                  Section 6.1 CONFIDENTIALITY. (a) Each Shareholder hereby
agrees that Confidential Information (as defined below) furnished and to be
furnished to it was and will be made available in connection with such
Shareholder's investment in the Company. Each Shareholder agrees that it will
use the Confidential Information only in connection with its investment in the
Company and not for any other purpose. Each Shareholder further acknowledges and
agrees that it will not disclose any Confidential Information to any Person;
provided that Confidential Information may be disclosed (i) to such
Shareholder's Representatives (as defined below) in the normal course of the
performance of their duties or to any financial institution providing credit to
such Shareholder, (ii) to the extent required by applicable law, rule or
regulation (including complying with any oral or written questions,
interrogatories, requests for information or documents, subpoena, civil
investigative 



                                       59

demand or similar process to which a Shareholder is subject; provided that such
Shareholder gives the Company prompt notice of such request(s), to the extent
practicable, so that the Company may seek an appropriate protective order or
similar relief (and the Shareholder shall cooperate with such efforts by the
Company, and shall in any event make only the minimum disclosure required by
such law, rule or regulation)), (iii) to any Person to whom such Shareholder is
contemplating a Transfer of its Shares (provided that such Transfer would not be
in violation of the provisions of this Agreement and as long as such potential
Transferee is advised of the confidential nature of such information and agrees
to be bound by a confidentiality agreement in form and substance satisfactory to
the Company (it being understood that a confidentiality agreement consistent
with the provisions hereof shall be satisfactory to the Company)) or (iv) if the
prior written consent of the Board shall have been obtained. Nothing contained
herein shall prevent the use (subject, to the extent possible, to a protective
order) of Confidential Information in connection with the assertion or defense
of any claim by or against the Company or any Shareholder. Notwithstanding the
foregoing, each Shareholder or Affiliate of a Shareholder who engages
principally in the business of effecting or recommending transactions, either as
a principal or as agent on behalf of third parties, in, relating to or involving
securities (including public securities of the Company or its subsidiaries) and
including, without limitation, transactions in which such Shareholder or
Affiliate may act as an investment advisor, an investment company, a broker or
dealer in securities, an underwriter or placement agent of securities, a market
maker, a specialist, an arbitrageur, a block positioner or a provider of
securities research, may engage in such activities with respect to securities of
the Company so long as, prior to engaging in any such activities (i) 




                                       60
<PAGE>   65

such Shareholder has established an effective "ethical wall" between individuals
receiving Confidential Information and those individuals (including Affiliates)
involved in effectuating trades or other transactions involving such securities
of the Company or its subsidiaries, which "ethical wall" is designed to prevent
any transfer, directly or indirectly, of Confidential Information and (ii) such
purchases, sales, dealings or other transactions are made only in accordance
with such "ethical wall" policies and procedures in accordance with applicable
law, rule or regulation.

                           (b) "Confidential Information" means any information
concerning the Company and Persons which are or become its subsidiaries or the
financial condition, business, operations or prospects of the Company and
Persons which are or become its subsidiaries in the possession of or furnished
to any Shareholder (including, without limitation by virtue of its present or
former right to designate a director of the Company); provided that the term
"Confidential Information" does not include information which (i) is or becomes
generally available to the public other than as a result of a disclosure by a
Shareholder or its partners, directors, officers, employees, agents, counsel,
investment advisers or representatives (all such persons being collectively
referred to as "Representatives") in violation of the Merger Agreement or this
Agreement, (ii) is or was available to such Shareholder on a nonconfidential
basis prior to its disclosure to such Shareholder or its Representatives by the
Company or (iii) was or becomes available to such Shareholder on a
non-confidential basis from a source other than the Company, provided that such
source is or was (at the time of receipt of the relevant information) not, to
the best of such Shareholder's knowledge, bound by a confidentiality agreement
with (or other confidentiality obligation to) the Company or another Person.

                  Section 6.2 REPORTS. The Company will furnish all the Equity
Investors with the quarterly and annual financial reports that the Company is
required to file with the Securities and Exchange Commission pursuant to Section
13 or Section 15(d) of the Exchange Act promptly after the filing thereof or, in
the event the Company is not required to file such reports, quarterly and annual
reports containing the same information as would be required in such reports on
the date that such reports would otherwise be filed.

                  Section 6.3 LIMITATIONS ON SUBSEQUENT REGISTRATION. The
Company shall not enter into any agreement with any holder or prospective holder
of any securities of the Company (a) which conflicts with the provision of
Article V, (b) that would allow such holder or prospective holder to include
such securities in any registration filed pursuant to Section 5.1 or 5.2 hereof,
unless under the terms of such agreement, such holder or prospective holder may
include such securities in any such registration only to the extent that the
inclusion of such securities would not reduce the amount of the Registrable
Securities of the Shareholders included therein or (c) on terms otherwise more
favorable than this Agreement.

                  Section 6.4 LIMITATION ON PURCHASE OF EQUITY SECURITIES. Until
the earlier to occur of (i) the seventh anniversary of the Closing Date or (ii)
the date on which at least 40% of the outstanding Common Stock on a Fully
Diluted basis of the Company is held by Persons other than the Shareholders (the
"Trigger Date"), no Non-THL Shareholder shall acquire any Equity Securities
except if (A) with respect to each Institutional Shareholder, such Shareholder
may acquire Equity Securities in a purchase of Equity Securities pursuant to
Section 4.3 or 4.4 hereof, (B) with respect to each 



                                       62
<PAGE>   67

Management Shareholder, such Shareholder may acquire Equity Securities either in
a purchase of Equity Securities pursuant to Section 4.3 or 4.4 hereof or in any
other transaction so long as THL has been notified at least five Business Days
in advance and if given a reasonable opportunity to consult with such
Shareholder prior to the purchase or (C) in a Transfer from any other Non-THL
Shareholder which is otherwise permitted under the terms of Article 3 hereof.

                  Section 6.5  REGULATED STOCKHOLDERS.

                  (a) If a Regulated Stockholder determines that it has a
Regulatory Problem, the Company agrees to take all such actions, subject to
Applicable Law, as are reasonably requested by such Regulated Stockholder (i) to
effectuate and facilitate any transfer by such Regulated Stockholder of any
Equity Securities of the Company then held by such Regulated Stockholder to any
Person designated by such Regulated Stockholder, (ii) to permit such Regulated
Stockholder (or any Affiliate of such Regulated Stockholder) to exchange all or
any portion of the voting Equity Securities then held by such Person on a
share-for-share basis for shares of a class of non-voting Equity Securities of
the Company, which non-voting Equity Securities shall be convertible into voting
Equity Securities on such terms as are requested by such Regulated Stockholder
in light of regulatory considerations then prevailing, and (iii) to continue and
preserve the respective allocation of the voting interests with respect to the
Company provided for in this Agreement and with respect to such Regulated
Stockholder's ownership of the Company's voting Equity Securities. Such actions
may include, without limitation, (x) entering into such additional agreements as
are reasonably requested by such Regulated Stockholder to permit any Person(s)
designated by such Regulated Stockholder to exercise any voting power which is


                                       63
<PAGE>   68

relinquished by such Regulated Stockholder upon any exchange of voting Equity
Securities for non-voting Equity Securities of the Company, and (y) entering
into such additional agreements, adopting such amendments to the charter
documents of the Company and taking such additional actions as are reasonably
requested by such Regulated Stockholder in order to effectuate the intent of the
foregoing.

                  (b) If a Regulated Stockholder has the right or opportunity to
acquire any of the Company's Equity Securities from the Company, any Stockholder
or any other Person (as the result of a preemptive offer, pro rata offer or
otherwise), at such Regulated Stockholder's request, the Company will offer to
sell (or if the Company is not the seller, to cooperate with the seller and such
Regulated Stockholder to permit such seller to sell) such non-voting Equity
Securities on the same terms as would have existed had such Regulated
Stockholder acquired the Equity Securities so offered and immediately requested
their exchange for non-voting Equity Securities pursuant to clause (a) above.

                  (c) The Company agrees not to amend or waive the voting or
other provisions of this Agreement or the Company's charter documents if such
amendment or waiver would cause any Regulated Stockholder to have a Regulatory
Problem; provided that any such Regulated Stockholder notifies the Company that
it would have a Regulatory Problem promptly after it has notice of such
amendment or waiver.

right, remedy, obligation or liability arising hereunder or by reason hereof
shall be assignable by the Company or any Shareholder; provided that any Person
acquiring shares of Common Stock who is required by the terms of this Agreement
to become a party hereto shall execute and deliver to the Company an agreement
to be bound by this Agreement and shall thenceforth be a "Shareholder."

                           (b) Any Permitted Transferee of a Management
Shareholder who shall become a party hereto shall be deemed a "Management

of this Agreement may be waived except by an instrument in writing executed by
the party against whom the waiver is to be effective. No provision of this
Agreement may be amended or otherwise modified except by an instrument in
