         "VESTED OPTIONS" shall mean, as of any date, options, securities and
other rights to acquire from the Company, by exercise, conversion, exchange or
otherwise, shares of Common Stock or securities convertible into Common Stock,
which are vested and exercisable within 60 days of such date of measurement.

         "VOTING STOCK" shall mean the Common Stock, Common Stock Equivalents

                                  ARTICLE II

                  Rights With Respect To The Subject Securities

         2.1      Limited Rights of Transfer.

                  (a)      Transfers. Except for the JWC Holders, no Stockholder
shall Transfer all or any part of the Subject Securities at the time held by
such Stockholder. Subject to Section 2.1(b), no Transfer of or attempt to
Transfer any Subject Securities in violation of the preceding sentence shall be
effective or valid for any purpose. No Transfer of any Subject Securities shall
be effective or valid under this Section 2.1(a) if such Transfer constitutes a
Prohibited Transfer, or unless and until the transferee executes and delivers to
the Company a Joinder Agreement in accordance with Section 2.13 hereof.

                  (b)      Exceptions. Notwithstanding Section 2.1(a), a
Transfer may be effectively and validly made hereunder if such Transfer is not a
Prohibited Transfer and is either (i) a Permitted Transfer, (ii) made pursuant
to the registration rights granted under Article III hereof, (iii) made pursuant
to and/or following a Public Offering, (iv) made pursuant to Sections 2.2, 2.3
(as a Participating Offeree), 2.4 or 2.5 or (v) made with the written consent of
the holders of a majority of the Common Stock Equivalents at the time held by
the JWC Holders (or the JWC Representative) and the holders of a majority of the
Common Stock Equivalents at the time held by the Halifax Holders (or the Halifax
Representative). No Transfer of any Subject Securities shall be effective or
valid under this Section 2.1(b) if such Transfer constitutes a Prohibited
Transfer. In addition, no Transfer shall be effective or valid under this
Section 2.l(b) unless and until the transferee executes and delivers to the
Company a Joinder Agreement in accordance with Section 2.13 hereof.

         2.2      Right of First Refusal.

                  (a)      Notice of Offer. If (i) at any time any Halifax
Holder, Management Holder, Additional Holder or any of their Permitted
Transferees (the "OFFERING HOLDER") receives a bona


                                       11

fide offer to purchase any or all of such Offering Holder's Subject Securities
(the "TRANSFER STOCK") from any Third Party (other than to a Permitted
Transferee) (the "OFFEROR") and (ii) such Offering Holder wishes to accept such
offer (a "TRANSFER OFFER"), then the Offering Holder shall cause the Transfer
Offer to be reduced to writing and shall provide a notice containing the offer
to purchase specified below (the "TRANSFER NOTICE") to the Company and all other
Stockholders. The Transfer Notice shall be accompanied by a true and correct
copy of the Transfer Offer (which shall identify in reasonable detail all
material terms, including, but not limited to, the Offeror, the Transfer Stock,
the price contained in the Transfer Offer and all the other terms and conditions
of the Transfer Offer). The Transfer Notice shall constitute an irrevocable
offer to sell any or all of the Transfer Stock to the Company and to all other
Stockholders within 30 days of receipt by the Company of the Transfer Notice
(the "OFFER PERIOD"). During the Offer Period, subject to the limitation in the
next sentence, any combination of the Company and/or the other Stockholders will
have the right and option to purchase all of the Transfer Stock at a price equal
to the price contained in the Transfer Offer and upon the same terms as
contained in the Transfer Offer. During the first 15 days of the Offer Period
(the "COMPANY EXCLUSIVE FIRST REFUSAL PERIOD"), the Company shall have the
exclusive right and option to purchase all of the Transfer Stock. Following the
expiration of the Company Exclusive First Refusal Period, if the Company has not
opted to purchase all of the Transfer Stock, the Company and any combination of
the other Stockholders may purchase all of the Transfer Stock. For the avoidance
of doubt, unless the Offering Holder shall have consented to the purchase of
less than all of the Transfer Stock by the Company and/or the other
Stockholders, neither the Company nor any Stockholder, nor any combination of
the Company and any Stockholder may purchase any Transfer Stock pursuant to the
foregoing provisions unless all of the Transfer Stock is to be so purchased
(whether by the Company, the other Stockholders, or any combination thereof).
Notwithstanding any other provision of this Agreement, unless otherwise agreed
to by at least 50% of the Subject Securities held by the JWC Holders and 50% of
the Subject Securities held by the Halifax Holders, no Management Holder or
Additional Holder may Transfer their Subject Securities in exchange for
consideration other than cash.

                  (b)      Closing of Transfer Stock. If, during the Offer
Period, the Company, or any combination of the Company and the other
Stockholders, has accepted the offer contained in the Transfer Notice, the
closing of the purchase of such Transfer Stock shall take place at the principal
offices of the Company within 10 days of such acceptance. At such closing, the
Company and/or the other Stockholders, as applicable, and/or its or their
designees, as the case may be, shall deliver a certified check or checks
calculated at the price set forth in the Transfer Notice to the Offering Holder
against delivery of certificates and/or other instruments representing the
Transfer Stock, together with stock or other appropriate powers duly endorsed
with respect to the Transfer Stock, free and clear of all Liens (other than
pursuant to securities laws, this Agreement or a Stock Option Agreement). All of
the foregoing deliveries will be deemed to be made simultaneously and none shall
be deemed completed until all have been completed.

                  (c)      Completion of Sale to Third Party. If, during the
Offer Period, neither the Company nor any combination of the Company and the
other Stockholders has accepted the offer contained in the Transfer Notice in
writing as to all the Transfer Stock covered thereby, or within 15 days of
acceptance by any combination of the Company and any Stockholder the closing has
not occurred, and Section 2.4 does not apply to such Transfer, then during the
next 60 days, the Offering


                                       12

Holder may sell the Transfer Stock to the Offeror at the price and on the other
terms contained in the Transfer Notice. No sale may be made by the Offering
Holder to any Offeror if such sale would constitute a Prohibited Transfer or
unless and until such Offeror executes and delivers to the Company a Joinder
Agreement in accordance with Section 2.13 hereof. Promptly after any sale
pursuant to this Section 2.2, the Offering Holder shall furnish such evidence of
the completion (including time of completion) of such sale and of the terms
thereof as the Company may reasonably request. If the Offering Holder has not
completed the sale of the Transfer Stock during the applicable period referred
to above, such Offering Holder shall no longer be permitted to sell such shares
pursuant to this Section 2.2 without again fully complying with the provisions
of this Section 2.2 and all the restrictions on sale, transfer or assignment
contained in this Agreement shall again be in effect with respect to the
Transfer Stock.

         2.3      Tagalong. No JWC Holder shall Transfer any shares of Subject
Securities to a Third Party (other than a Permitted Transferee) in one or a
series of related bona fide arm's-length transactions without complying with the
terms and conditions set forth in this Section 2.3; provided, however, that the
JWC Holders shall be permitted to Transfer up to 5%, in the aggregate, of the
number of shares of Subject Securities held by the Original JWC Holders as of
the date of this Agreement without compliance with this Section 2.3; provided
further, however, that this Section 2.3 shall not in any way limit or affect the
restriction contained in the last sentence of Section 2.1(a).

                  (a)      Any JWC Holder (the "INITIATING STOCKHOLDER")
desiring to Transfer shares of Subject Securities subject to the restriction in
Section 2.3 shall give not less than 10 Business Days' prior written notice of
such intended Transfer to each other Stockholder ("PARTICIPATING OFFEREES") and
to the Company. Such notice (the "PARTICIPATION NOTICE") shall set forth general
terms and conditions of such proposed Transfer, including the name of the
prospective transferee, the number of Subject Securities proposed to be
transferred to the extent known (the "PARTICIPATION SECURITIES") by the
Initiating Stockholder, the purchase price per share to the extent known
proposed to be paid therefor and the payment terms and type of Transfer to be
effectuated. Within 10 Business Days following the delivery of the Participation
Notice by the Initiating Stockholder to each Participating Offeree and to the
Company, each Participating Offeree shall, by notice in writing to the
Initiating Stockholder and to the Company, have the opportunity and right to
sell to the purchasers in such proposed Transfer (upon the same terms and
conditions as the Initiating Stockholder). If the Halifax Holder is a
Participating Offeree, the Halifax Holder shall have the opportunity and right
to include in such proposed Transfer an amount of Subject Securities
representing the same proportion (i.e., in relation to the aggregate amount at
the time held by the Halifax Holders) of the Subject Securities being sold by
the Initiating Stockholder (i.e., in relation to the aggregate amount at the
time held by the JWC Holders). Other Participating Offerees shall have the
opportunity and right to include in such proposed Transfer an amount of Subject
Securities up to that number of Subject Securities representing Subject
Securities at the time held by such Participating Offeree as shall equal the
product of (i) a fraction, the numerator of which is the number of Subject
Securities owned by such Participating Offeree as of the date of such proposed
Transfer and the denominator of which is the aggregate number of Subject
Securities owned as of the date of such Participation Notice by each Initiating
Stockholder and by all Participating Offerees so electing to sell Subject
Securities pursuant to this Section 2.3(a), multiplied by (ii) the number of
Subject Securities proposed to be transferred.


                                       13

                  (b)      At the closing of any proposed Transfer in respect of
which a Participation Notice has been delivered, the Initiating Stockholder,
together with all Participating Offerees so electing to sell Subject Securities
pursuant to Section 2.3(a) shall execute and deliver such documents or
instruments reasonably requested by the proposed transferee and deliver to the
proposed transferee certificates and/or other instruments representing the
Subject Securities to be sold, free and clear of all Liens, together with stock
or other appropriate powers duly endorsed therefor, and shall receive in
exchange therefor the consideration to be paid or delivered by the proposed
transferee in respect of such Subject Securities as described in the
Participation Notice.

                  (c)      The provisions of this Section 2.3 shall not apply to
(i) any Transfer pursuant to a Public Offering or, following a Public Offering,
pursuant to a Rule 144 Transaction or (ii) any Transfers pursuant to Section 2.4
hereof.

         2.4      Dragalong.

                  (a)      If the JWC Holders (the "DRAGALONG GROUP") determine
to sell or exchange (in a sale or exchange of securities of the Company or in a
merger, consolidation or other business combination or any similar transaction)
in one or a series of related bona fide arms-length transactions to an
unaffiliated Third Party and not pursuant to a Permitted Transfer, at least 50%
of the Subject Securities (which defined term shall, for purposes of this
Section 2.4 only, include all Subject Securities regardless of vesting or
exercisability) at the time held by the JWC Holders, then upon 10 days' written
notice from the Dragalong Group to the other Stockholders, which notice shall
include reasonable details and all material terms of the proposed sale or
exchange, including the proposed time and place of closing and the form and
amount of consideration to be received by the Stockholders (such notice being
referred to as the "SALE REQUEST"), each other Stockholder shall be obligated
to, and shall, (i) sell, transfer and deliver, or cause to be sold, transferred
and delivered, to such Third Party the proportion of such Stockholder's Subject
Securities as is being sold by the JWC Holders in the same transaction at the
closing thereof (and shall (A) execute and deliver such agreements for the
purchase of such Subject Securities and other agreements, instruments and
certificates as the members of the Dragalong Group shall execute and deliver in
connection with such proposed transaction and (B) deliver certificates and/or
other instruments representing the proportion of such Stockholder's Subject
Securities being sold, together with stock or other appropriate powers therefore
duly executed, at the closing, free and clear of all Liens), and each
Stockholder shall receive upon the closing of such transaction the pro rata
portion (as defined below) of the consideration to be paid or delivered by the
proposed transferee in respect of such Stockholder's Subject Securities as shall
be payable to the members of the Dragalong Group in respect of their Subject
Securities (in the case of Options, warrants or other Common Stock Equivalents,
subject to subtraction of the exercise price) and (ii) if stockholder approval
of the transaction is required, vote such Stockholder's Common Stock in favor
thereof. The "PRO RATA PORTION" of each Stockholder shall be the number of
Subject Securities issued to and owned by such Stockholder multiplied by a
fraction, the numerator of which shall be the number of Subject Securities the
JWC Holders wish to Transfer, and the denominator of which shall be the
aggregate number of Subject Securities issued to or beneficially owned by the
JWC Holders participating in the sale.


                                       14

                  (b)      Each Stockholder shall be severally obligated to join
on a pro rata basis (based on such Stockholder's pro rata share of the net
proceeds paid by such Third Party) in an indemnification that is to be provided
in connection with such Sale, other than any such indemnification that relates
specifically to a particular Stockholder; provided that no Stockholder shall be
obligated in connection with such Sale to agree to indemnify or hold harmless
the Third Party with respect to an amount in excess of the net cash proceeds
paid to such Stockholder in connection with such Sale. All Stockholders will
bear their pro rata share of the costs and expenses incurred in connection with
such Sale to the extent such costs are incurred for the benefit of all
Stockholders and are not otherwise paid by the Company to the Third Party.

                  (c)      Each Stockholder agrees that, in such Stockholder's
capacity as a stockholder of the Company, such Stockholder shall, including
pursuant to Section 2.4(a) hereof, vote, or grant proxies relating to the Common
Stock at the time held by such Stockholder to vote, all of such Stockholder's
Common Stock in favor of any sale or exchange of securities of the Company or
any merger, consolidation, recapitalization, reorganization or other business
combination or any similar transaction, including pursuant to Section 2.4(a)
hereof, if, and to the extent that, approval of the Company's stockholders is
required in order to effect such transaction.

                  (d)      If, at the end of 90 days following the receipt by
the Stockholders of a Sale Request, the Dragalong Group has not completed the
sale, (i) each Stockholder shall be released from its obligation under the Sale
Request, (ii) the Dragalong Group shall return to each Stockholder all
certificates evidencing unsold Subject Securities and all related powers of
attorney and instruments of transfer, if any, and (iii) it shall be necessary
for a new and separate Sale Request to be furnished and the terms and provisions
of this Section 2.4 to be separately complied with in order to consummate such
sale pursuant to this Section 2.4, unless the failure to complete such sale
resulted from any failure by any Stockholder to comply in any material respect
with the terms of this Section 2.4.

         2.5      Call by the Company.

                  (a)      (i)      If the employment of a Management Holder
with the Company and any of its Subsidiaries shall terminate (a "CALL EVENT")
for any reason, then, subject to Section 2.5(a)(ii), the Company shall have the
right to purchase (the "CALL OPTION"), by delivery of a written notice (the
"CALL NOTICE") to such terminated Management Holder (with a copy thereof to the
JWC Representative) no later than 30 days after the date of the Call Event (the
"COMPANY CALL PERIOD"), and such Management Holder and such Management Holder's
direct and indirect Permitted Transferees (a "CALL GROUP") shall be required to
sell any and all of the Subject Securities that are owned by such Call Group on
the date of the Call Event (such Subject Securities to be purchased hereunder
being referred to collectively as the "CALL SECURITIES") at, except as otherwise
provided in Section 2.5(a)(ii) hereof, a price per share equal to the greater of
(I) the Call Price of such Call Securities as of the date of the Call Event and
(II) the Cost Price of such Call Securities.

                           (ii)     Notwithstanding anything set forth in this
Section 2.5 to the contrary, in the event a Management Holder resigns, other
than upon death or disability, without Good Reason from his employment with the
Company and its Subsidiaries, or his employment is terminated for


                                       15

Cause by the Company and its Subsidiaries, then the purchase price per share
payable for the Call Securities shall be an amount equal to the Cost Price of
such Call Securities; provided, however, that if a Management Holder resigns six
or more years from the issuance of the Call Securities (or Common Stock
Equivalents that were converted or exercised into such Call Securities), then
the purchase price per share payable for the Call Securities shall equal the
greater of (I) the Call Price of such Call Securities as of the date of the Call
Event and (II) the Cost Price of such Call Securities.

                  (b)      The closing of any purchase of Call Securities by the
Company from a Call Group pursuant to this Section 2.5 shall take place at the
principal office of the Company on such date within 15 days after the expiration
of the Company Call Period with respect to such Call Group as the Company shall
specify to the members of such Call Group in writing. At such closing, the
members of the Call Group shall deliver to the Company, against payment by the
Company of the purchase price for the Call Securities in cash (by delivery of a
certified check or checks payable to the respective members of the Call Group,
as the case may be), certificates and/or other instruments representing,
together with stock or other appropriate powers duly endorsed with respect to,
the Call Securities, free and clear of all Liens (other than pursuant to
securities laws, this Agreement or a Stock Option Agreement). All of the
foregoing deliveries will be deemed to be made simultaneously and none shall be
deemed completed until all have been completed.

                  (c)      Notwithstanding anything set forth in this Section
2.5 to the contrary, prior to the exercise by the Company of its Call Option to
purchase Call Securities pursuant to this Section 2.5, one or more prospective
or existing employees of the Company or any Subsidiary may be designated by the
Board of Directors (individually, a "DESIGNATED EMPLOYEE" and, collectively,
"DESIGNATED EMPLOYEES") who shall have the right, but not the obligation, to
exercise the Call Option and to acquire, in lieu of the Company, some or all (as
determined by the Company) of the Call Securities that the Company is entitled
to purchase from the Call Group hereunder, for cash and otherwise on the same
terms and conditions as set forth in Section 2.5(b) which apply to the
repurchase of Call Securities by the Company. Concurrently with any such
purchase of Call Securities by any such Designated Employee, such Designated
Employee shall execute a counterpart of this Agreement whereupon such Designated
Employee shall be deemed a "Management Holder" and shall have the same rights
and be bound by the same obligations as the other Management Holders hereunder.
Payment under this Section 2.5(c) and under Section 2.5(d) below shall be made
by a certified check or checks payable to the respective members of the Call
Group, in an amount equal to the purchase price for such Call Securities under
Section 2.5(a) hereof against delivery of certificates and/or other instruments
representing, together with stock or other appropriate powers duly endorsed with
respect to such Call Securities, free and clear of all Liens (other than
pursuant to securities laws, this Agreement or a Stock Option Agreement). All of
the foregoing deliveries will be deemed to be made simultaneously and none shall
be deemed completed until all have been completed.

                  (d)      If and to the extent neither the Company nor any
Designated Employee elects to exercise the Call Option and deliver a Call Notice
prior to the expiration of the Company Call Period with respect to such
Management Holder, then the JWC Holders and the Halifax Holders, pro rata in
accordance with the respective Common Stock Equivalents at the time held by the
JWC Holders and the Halifax Holders so exercising their rights under this
Section 2.5(d), may exercise


                                       16

the Call Option in lieu of the Company and such Designated Employee by delivery
of a Call Notice to such terminated Management Holder within the Company Call
Period. The closing of any purchase of Call Securities by such JWC Holders and
the Halifax Holders shall take place at the principal offices of the Company on
such date within 15 days after the expiration of the Company Call Period with
respect to such Management Holder as the holders of a majority of the Common
Stock Equivalents at the time held by the JWC Holders and the Halifax Holders so
exercising their rights under this Section 2.5(d) shall specify to the members
of such Call Group in writing, provided that if any such JWC Holder or Halifax
Holder fails to purchase all or a portion of the number of Call Securities which
such JWC Holder or Halifax Holder may purchase pursuant to this Section 2.5(d),
then the other JWC Holders and the Halifax Holders so exercising their rights
under this Section 2.5(d) shall be entitled to purchase such Call Securities
(pro rata based upon their respective Common Stock Equivalents at the time held,
or as otherwise agreed, by such JWC Holders and the Halifax Holders).

                  (e)      If and to the extent none of the Company, any
Designated Employees, any JWC Holders or any Halifax Holder elects to exercise
the Call Option and deliver a Call Notice within the Company Call Period or if
the closing of the purchase of all Call Securities does not occur within 15 days
after the expiration of the Company Call Period, then the Call Option provided
for in this Section 2.5 shall terminate with respect to such Subject Securities
not so purchased under this Section, but the parties hereto shall continue to be
bound by the remaining provisions of this Agreement.

                  (f)      Notwithstanding the foregoing with respect to any
shares of Common Stock which, as of the date of the purchase and sale pursuant
to this Call Option, (i) were purchased as the result of the exercise of a stock
option and (ii) have not been owned by the Call Group for at least 180 days
("UNMATURED SHARES"), the closing with respect to such Unmatured Shares shall be
delayed until a date no later than the 10th day after the 180th day following
the acquisition by the Call Group of such Unmatured Shares and the purchase
price for such Unmatured Shares will be determined at the time of such delayed
closing.

         2.6      Put by the Management Holders.

                  (a)      If a Call Event occurs by reason of a Management
Holder terminating his employment with the Company and any of its Subsidiaries
for Good Reason or his employment being terminated without Cause by the Company
and any of its Subsidiaries, then such Management Holder shall have the right to
require the Company to purchase (the "PUT OPTION"), by delivery of a written
notice (the "PUT NOTICE") to the Company during the 30-day period after the
expiration of the Company Call Period pertaining to such Management Holder (the
"PUT PERIOD"), and the Company shall be required to purchase all of the Subject
Securities described in the Put Notice (other than Subject Securities purchased
under Section 2.5) (such Subject Securities to be purchased hereunder being
referred to collectively as the "PUT SECURITIES") at a price per share equal to
the Put Price; provided that if a Management Holder exercises a Put Option
within 18 months of the date hereof the Company shall be required to purchase
all of the Subject Securities described in the Put Notice at a price per share
equal to the Call Price.


                                       17

                  (b)      The closing of any purchase of Put Securities by the
Company from a Management Holder pursuant to this Section 2.6 shall take place
at the principal office of the Company on such date within 15 days after the
expiration of the Put Period with respect to such Management Holder as the
Company shall specify to such Management Holder in writing. At such closing, the
Management Holder shall deliver to the Company, against payment by the Company
of the purchase price for the Put Securities in cash (by delivery of a certified
check payable to the Management Holder) or, if the Company is required by its
senior lenders, by subordinated promissory note with a ten year maturity and
interest paid at the prime rate announced from time to time by the Company's
senior lenders (such interest payable in kind), certificates and/or other
instruments representing, together with stock or other appropriate powers duly
endorsed with respect to, the Put Securities, free and clear of all Liens (other
than pursuant to securities laws, this Agreement or a Stock Option Agreement).
All of the foregoing deliveries will be deemed to be made simultaneously and
none shall be deemed completed until all have been completed.

                  (c)      If and to the extent a Management Holder elects not
to exercise the Put Option and deliver a Put Notice within the Put Period or if
the closing of the purchase of all Put Securities does not occur within 15 days
after the expiration of the Put Period through the fault of such Management
Holder, then the Put Option provided for in this Section 2.6 shall terminate
with respect to such Subject Securities not so purchased under this Section, but
the parties hereto shall continue to be bound by the remaining provisions of
this Agreement.

                  (d)      Notwithstanding the foregoing with respect to any
shares of Common Stock which, as of the date of the purchase and sale pursuant
to this Put Option, were Unmatured Shares, the closing with respect to such
Unmatured Shares shall be delayed until a date no later than the 10th day after
the 180th day following the acquisition by the Management Holder of such
Unmatured Shares and the purchase price for such Unmatured Shares will be
determined at the time of such delayed closing.

         2.7      Restrictions on Other Agreements. No Stockholder shall grant
any proxy or enter into or agree to be bound by any voting trust with respect to
any Subject Securities other than as set forth in this Agreement nor shall any
Stockholder enter into any stockholders agreements or arrangements of any kind
with any Person with respect to any of the Subject Securities on terms which
conflict with the provisions of this Agreement (whether or not such agreements
and arrangements are with other Stockholders or holders of Common Stock
Equivalents that are not parties to this Agreement), including but not limited
to, agreements or arrangements with respect to the acquisition, disposition or
voting of Subject Securities inconsistent herewith.

         2.8      Transfer Subject Hereto. Except as otherwise provided in this
Agreement, in the event of an Involuntary Transfer (as defined in the following
sentence) of any Subject Securities (the "TRANSFERRED SECURITIES") of any JWC
Holder, Halifax Holder, Management Holder or Additional Holder to any Person,
the transferee, including, without limitation, any and all transferees and
subsequent transferees of the initial transferee (the "INVOLUNTARY TRANSFEREE"),
shall take and hold the Transferred Securities subject to this Agreement and to
all of the obligations of, and restrictions imposed hereby upon, the transferor
holder and shall comply with this Agreement. As used in this Agreement, the term
"Involuntary Transfer" shall mean any transaction, proceeding or action by or


                                       18

in which the JWC Holder, Halifax Holder, Management Holder or Additional Holder
is involuntarily deprived or divested of any right, title or interest in or to
any of such holder's Subject Securities (including, without limitation, a
seizure under levy of attachment or execution, a foreclosure under a pledge of
Subject Securities, a transfer to a trustee in bankruptcy or receiver or other
officer or agency, or a transfer to a state or to a public officer or agency
pursuant to a statute pertaining to escheat or abandoned property but
specifically excluding death, incapacity, divorce and similar events).

         2.9      Provisions in the Event of Involuntary Transfers. In the event
of an Involuntary Transfer, the Stockholders and the Company shall not take any
action to approve any such involuntary transfer not in accordance with this
Section, and the transferor Stockholder (or, if it fails to do so, the
Involuntary Transferee) shall forthwith give notice (the "INVOLUNTARY TRANSFER
NOTICE") to the Company stating (i) when the involuntary transfer occurred or is
to occur, (ii) the circumstances alleged to require such involuntary transfer,
(iii) the number and type of securities involved and (iv) the name, address and
capacity of the Involuntary Transferee.

         2.10     Option. If an Involuntary Transfer of the Subject Securities
of any Stockholder occurs, the Company and its designees shall have the same
rights of first refusal with respect to the Transferred Shares as if the
involuntary transfer had been a proposed voluntary transfer by the transferor
Stockholder governed by Section 2.2 except that: (i) the periods within which
such right must be exercised shall run from the date the Involuntary Transfer
Notice is given in accordance with this Agreement; and (ii) such rights shall be
exercised by notice to the Involuntary Transferee rather than to the transferor
Stockholder. The closing of any purchase of Transferred Shares pursuant to this
Section shall be in accordance with the procedures set forth in Section 2.2.

         2.11     (a) Purchase for Investment; Legend on Certificate. Each
Stockholder acknowledges that all of the securities of the Company held by such
Stockholder are being (or have been) acquired for investment and not with a view
to the distribution thereof and that no Transfer, hypothecation or assignment of
any such securities (including the Common Stock for which such securities may be
exercisable or exchangeable or into which such securities may be convertible)
may be made except in compliance with applicable federal and state securities
laws. All the certificates or other instruments representing any of such
securities (including the Common Stock for which such securities may be
exercisable or exchangeable or into which such securities may be convertible)
which are now or hereafter held by any Stockholder shall be subject to the terms
of this Agreement and shall have endorsed in writing, stamped or printed,
thereon the following legends:

         "THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO THE
         TERMS AND CONDITIONS OF AN AMENDED AND RESTATED STOCKHOLDERS AGREEMENT
         DATED AS OF OCTOBER 17, 2001, AS AMENDED FROM TIME TO TIME, A COPY OF
         WHICH IS ON FILE WITH AND AVAILABLE FROM THE SECRETARY OF THE COMPANY."

         "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
         REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE
         STATE SECURITIES LAWS AND MAY NOT BE SOLD,


                                       19

         ASSIGNED, TRANSFERRED, PLEDGED OR OTHERWISE DISPOSED OF EXCEPT IN
         COMPLIANCE WITH THE REQUIREMENTS OF SUCH ACT."

                  (b)      Removal of Legends, Etc. Notwithstanding the
provisions of Section 2.11(a) upon the transferability of any Subject
Securities, the restrictions thereunder shall cease and terminate when (i) such
Subject Securities are sold or otherwise disposed of in accordance with the
intended method of disposition by the seller or sellers thereof set forth in a
registration statement or are sold or otherwise disposed of in a transaction
which does not require that the securities transferred bear the legend set forth
in Section 2.11 or (ii) the holder of such Subject Securities has met the
requirement of transfer of such Subject Securities pursuant to subparagraph (k)
of Rule 144. Whenever the restrictions imposed by Section 2.11(a) shall
terminate, as herein provided, the holder of any Subject Securities shall be
entitled to receive from the Company, without expense, a new certificate not
bearing the restrictive legend set forth in Section 2.11(a) and not containing
any other reference to the restrictions imposed by Section 2.11(a).

         2.12     Effectiveness of Transfers. Any Subject Securities transferred
by a Stockholder (other than pursuant to an effective registration statement
under the Securities Act or a Rule 144 Transaction if the Subject Securities are
listed or admitted to trading on an Active Trading Market) shall be held by the
transferee thereof pursuant to this Agreement. Such transferee shall, except as
otherwise expressly stated herein, have all the rights and be subject to all of
the obligations of a Stockholder under this Agreement automatically and without
requiring any further act by such transferee or by any parties to this
Agreement. Without affecting the preceding sentence, if such transferee is not a
Stockholder on the dates of such transfer, then such transferee, as a condition
to such transfer, shall confirm such transferee's obligations hereunder in
accordance with Section 2.13 hereof. No Subject Securities shall be transferred
on the Company's books and records, and no transfer thereof shall be otherwise
effective, unless any such transfer is made in accordance with the terms and
conditions of this Agreement, and the Company is hereby authorized by all of the
Stockholders to enter appropriate stop transfer notations on its transfer
records to give effect to this Agreement.

         2.13     Additional Stockholders. Any Person that is not already a
party to this Agreement in the same Stockholder capacity as such Person would be
following the Transfer and who is acquiring any Subject Securities (except for
any acquisition thereof (a) in an offering registered under the Securities Act
or (b) in a Rule 144 Transaction if the Subject Securities are listed or
admitted to trading on an Active Trading Market) shall on or before the transfer
or issuance to it of such Subject Securities, sign and deliver to the Company a
Joinder Agreement and shall thereby become a party to this Agreement. If such
Person meets the definition of a JWC Holder, then such Person shall be treated
as a JWC Holder hereunder, if such Person meets the definition of a Halifax
Holder, such Person shall be treated as a Halifax Holder hereunder, if such
Person meets the definition of a Management Holder, such Person shall be treated
as a Management Holder hereunder, and if such Person meets none of the foregoing
definitions, such Person shall be treated as an Additional Holder hereunder. The
Company shall require each Person acquiring an option, warrant or other right to
purchase shares of Common Stock under any option or other equity participation
plan to execute a Joinder Agreement.


                                       20

         2.14     Notice of Transfer. Each JWC Holder, Halifax Holder,
Management Holder or Additional Holder agrees, prior to any Transfer of any
Subject Securities (except pursuant to an effective registration statement), to
give written notice to the Company of such holder's intent to effect such
Transfer and agrees to comply in all other respects with the provisions of this
Agreement. Each such notice shall describe the manner and circumstances of the
proposed Transfer and, unless the proposed Transfer is a Permitted Transfer or
unless waived by the Company, shall be accompanied by the written opinion,
addressed to the Company, of counsel for the holder of such Subject Securities
(which counsel shall be reasonably satisfactory to the Company), stating that in
the opinion of such counsel (which opinion shall be reasonably satisfactory to
the Company) such proposed Transfer does not involve a transaction requiring
registration or qualification of such Subject Securities under the Securities
Act or the securities laws of any state of the United States or of any foreign
jurisdiction. Subject to complying with the other applicable provisions of this
Agreement, such holder of Subject Securities shall be entitled to consummate
such Transfer in accordance with the terms of the notice delivered by it to the
Company if the Company does not object (on the basis that such Transfer violates
this Section 2.14) to such Transfer within 5 Business Days after the delivery of
such notice.

                                   ARTICLE III

                               Registration Rights

         3.1      General. For purposes of this Article III, (a) the terms
"REGISTER", "REGISTERED" and "REGISTRATION" refer to a registration effected by
preparing and filing a registration statement on Form S-1, S-2 or S-3 in
compliance with the Securities Act and the declaration or ordering of
effectiveness of such registration statement and (b) the term "HOLDER" means any
Stockholder electing to register any Registrable Securities pursuant to Section
3.2 or 3.3. The registration rights granted pursuant to Sections 3.2 and 3.3
shall terminate and expire on the fourth anniversary of the occurrence of a
Public Offering.

         3.2      Required Registration. If the Company shall be requested, in
writing, by the holders of a majority of the Common Stock Equivalents then held
by the JWC Holders (or the JWC Representative) to effect a registration
statement under the Securities Act of Registrable Securities, the Company shall
promptly (i) give written notice of the proposed registration to all other
Stockholders and (ii) use its best efforts to effect the registration under the
Securities Act of the Registrable Securities which the Company has been so
requested to register by the JWC Holders and by other Stockholders in a written
request received by the Company within 10 Business Days after the giving of the
written notice specified in clause (i) above; provided, however, that the
Company shall not be obligated to effect any registration under the Securities
Act except in accordance with the following provisions:

                  (a)      The Company shall not be obligated to use its best
efforts to file and cause to become effective any registration statement during
any period in which any other registration statement (other than on Forms S-4,
F-4 or S-8 promulgated under the Securities Act or any successor forms thereto)
pursuant to which Primary Shares are to be or were sold has been filed and not
withdrawn or has been declared effective within the prior 90 days.


                                       21

                  (b)      The Company may delay the filing or effectiveness of
any registration statement for a period of up to 90 days after the date of a
request for registration pursuant to this Section 3.2 if at the time of such
request (i) the Company is engaged, or has fixed plans to engage within 90 days
after the date of such request, in a firm commitment underwritten public
offering of Primary Shares in which the holders of Registrable Securities may
include Registrable Securities pursuant to Section 3.3 or (ii) a Material
Transaction exists, provided that the Company may only so delay the filing or
effectiveness of its registration statements (if any) once pursuant to this
Section 3.2(b).

                  (c)      With respect to any registration pursuant to this
Section 3.2, the Company may include in such registration any Primary Shares;
provided, however, that, if the managing underwriter advises the Company that
the inclusion of all Registrable Securities and Primary Shares proposed to be
included in such registration would interfere with the successful marketing
(including pricing) of the Registrable Securities proposed to be included in
such registration, then the number of Registrable Securities and Primary Shares
proposed to be included in such registration shall be included in the following
order:

                           (i)      first, the Registrable Securities requested
to be included in such registration (or, if necessary, such Registrable
Securities pro rata among the Holders of such Registrable Securities based upon
the number of Registrable Securities requested to be included in such
registration); and

                           (ii)     second, the Primary Shares.

                  (d)      If the method of disposition requested by the holders
pursuant to this Section 3.2 is an underwritten public offering, Stockholders
holding a majority of the Registrable Securities requested to be registered
shall have the right to designate the managing underwriter of such offering,
subject to the consent of the Company, which consent shall not be unreasonably
withheld.

                  (e)      At any time before the registration statement
covering Registrable Securities becomes effective, the Stockholders holding a
majority of the Registrable Securities requested to be registered may request
the Company to withdraw or not to file the registration statement.

         3.3      Piggyback Registration.

                  (a)      If, at any time, the Company determines to register
any Common Stock under the Securities Act in connection with a Public Offering
of such securities, the Company shall, at each such time, promptly give each
Stockholder written notice of such determination no later than 30 days before
its intended filing with the SEC. Upon the written request of any Stockholder
received by the Company within 10 Business Days after the giving of any such
notice by the Company, the Company shall use its best efforts to cause to be
registered under the Securities Act all of the Registrable Securities of such
Stockholder that such Holder has requested be registered for disposition in
accordance with the Company's intended method of disposition as stated in such
notice and with the underwriter selected by the Company. If the total amount of
Registrable Securities that are to be


                                       22

included by the Company in such registration exceeds the amount of securities
that the managing underwriters reasonably believe can be sold in an orderly
manner in such offering within a price range acceptable to the Company, then the
Company will include in such registration only the number of securities which in
the opinion of such underwriters can be sold in the manner described above, in
the following order:

                           (i)      first, all securities of the Company to be
         offered for the account of the Company; and

                           (ii)     second, the Registrable Securities requested
         to be included in such registration, (or if necessary, such Registrable
         Securities pro rata among the Holders of such securities based on the
         number of Registrable Securities requested to be included in such
         registration).

Notwithstanding the foregoing, the Company shall not be obligated to include in
an initial Public Offering any Registrable Securities of any Holder if the JWC
Holders do not elect to include their Registrable Securities in such a
registration. If any of the Holders disapproves of the terms of any such
underwriting, it may elect to withdraw therefrom by written notice to the
Company and the underwriter prior to the date of pricing such offer. Any
Registrable Securities or other securities excluded or withdrawn from such
underwriting shall be withdrawn from such registration.

         3.4      Obligations of the Company.

                  (a)      Whenever required under Section 3.2 or 3.3 to use its
best efforts to effect the registration of any Registrable Securities, the
Company shall (provided, that the Company may at any time delay or abandon the
underlying registration without any liability to the Holders):

                           (i)      prepare and file with the SEC a registration
         statement (or an amendment to a registration statement) with respect to
         such Registrable Securities and use its best efforts to cause such
         registration statement to become and remain effective, including,
         without limitation, filing of post-effective amendments and supplements
         to any registration statement or prospectus necessary to keep the
         registration statement current;

                           (ii)     as expeditiously as reasonably possible,
         prepare and file with the SEC such amendments and supplements to such
         registration statement and the prospectus used in connection with such
         registration statement as may be necessary to comply with the
         provisions of the Securities Act with respect to the disposition of all
         securities covered by such registration statement and to keep each
         registration and qualification under this Agreement effective (and in
         compliance with the Securities Act) by such actions as may be necessary
         or appropriate for a period of 120 days after the effective date of
         such registration statement (unless all securities covered by such
         registration statement are sooner disposed of), all as requested by
         such Holder or Holders;

                           (iii)    as expeditiously as reasonably possible
         furnish to the Holders such numbers of copies of a prospectus,
         including a preliminary prospectus, in conformity with


                                       23

         the requirements of the Securities Act, and such other documents as
         they may reasonably request in order to facilitate the disposition of
         Registrable Securities owned by them in accordance with the plan of
         distribution provided for in such registration statement;

                           (iv)     as expeditiously as reasonably possible use
         its best efforts to register and qualify the securities covered by such
         registration statement under such securities or "blue sky" laws of such
         jurisdictions as shall be reasonably appropriate for the distribution
         of the securities covered by the registration statement, provided that
         the Company shall not be required in connection therewith or as a
         condition thereto to qualify to do business in any jurisdiction it
         would not otherwise be required to qualify but for this subsection
         (iv), to file a general consent to service of process in any such
         jurisdiction or subject itself to taxation in any such jurisdiction,
         and further provided that (anything in this Agreement to the contrary
         notwithstanding with respect to the bearing of expenses) if any
         jurisdiction in which the securities shall be qualified shall require
         by law or regulation that expenses incurred in connection with the
         qualification of the securities in that jurisdiction be borne by
         selling stockholders, then such expenses shall be payable by selling
         stockholders pro rata, to the extent required by such jurisdiction;

                           (v)      notify each Holder of Registrable Securities
         covered by such registration statement, at any time when a prospectus
         relating thereto is required to be delivered under the Securities Act,
         upon discovery that, or upon the happening of any event as a result of
         which, the prospectus included in such registration statement, as then
         in effect, includes an untrue statement of a material fact or omits to
         state any material fact required to be stated therein or necessary to
         make the statements therein not misleading in the light of the
         circumstances under which they were made (provided that upon such
         notification, each Holder agrees not to sell or otherwise transfer or
         dispose of any Common Stock (or other securities) of the Company at the
         time held by such Holder or any interest or future interest therein
         until such statement or omission has been corrected, and there shall be
         added to the period during which the Company is obligated to keep such
         registration effective the number of days for which such sales or other
         transfers or dispositions were suspended), and at the request of any
         such Holder promptly prepare and furnish, without charge, to such
         seller or Holder a reasonable number of copies of a supplement to such
         prospectus or an amendment of such registration statement as may be
         necessary so that, as thereafter delivered to the purchasers of such
         securities, such prospectus shall not include an untrue statement of a
         material fact or omit to state a material fact required to be stated
         therein or necessary to make the statements therein not misleading in
         the light of the circumstances under which they were made;

                           (vi)     otherwise use its best efforts to comply
         with all applicable rules and regulations of the SEC, and make
         available to its security holders, as soon as reasonably practicable,
         an earnings statement covering the period of at least 12 months but not
         more than 18 months, beginning with the first full calendar month after
         the effective date of such registration statement, which earnings
         statement shall satisfy the provisions of Section 11(a) of the
         Securities Act or Rule 158 thereunder; and


                                       24

                           (vii)    use its best efforts to list all Registrable
         Securities covered by such registration statement on any securities
         exchange on which any class of similar Securities is then listed.

                  (b)      If the Company at any time proposes to register any
of its securities under the Securities Act subject to the registration rights of
the Holders under Section 3.2 or 3.3, and such securities are to be distributed
by or through one or more underwriters selected by the Company, then the Company
will make reasonable efforts, if requested by any Holder of Registrable
Securities who requests such registration, to arrange for such underwriters to
include such Registrable Securities among the securities to be distributed by or
through such underwriters.

                  (c)      In connection with the preparation and filing of each
registration statement registering Registrable Securities under this Agreement,
the Company will give the Holders of Registrable Securities on whose behalf such
Registrable Securities are to be so registered and their underwriters, if any,
and their respective counsel and accountants the opportunity to participate in
the preparation of such registration statement, each prospectus included therein
or filed with the SEC, and each amendment thereof or supplement thereto, and
will give each of them such access to its books and records and such
opportunities to discuss the business of the Company with its officers, its
counsel and the independent public accountants who have certified its financial
statements, as shall be reasonably necessary, in the opinion of such Holders or
such underwriters or their respective counsel, in order to conduct a reasonable
and diligent investigation within the meaning of the Securities Act.

         3.5      Furnish Information. It shall be a condition precedent to the
obligations of the Company to take any action pursuant to this Article III that
each Holder shall furnish to the Company such information regarding such Holder,
the Registrable Securities held by such Holder, and the intended method of
disposition of such securities as the Company shall reasonably request and as
shall be required in connection with the action to be taken by the Company.

         3.6      Expenses of Registration. Registration, filing and
qualification fees, printers' and accounting fees, fees and expenses of
compliance with securities or blue sky laws, fees and expenses relating to
filings with the National Association of Securities Dealers, Inc. or any
applicable securities exchange, fees of underwriters (excluding discounts,
commissions or fees of underwriters, selling brokers, dealer managers or similar
securities industry professionals attributable to the Registrable Securities
being registered), and fees and disbursements of counsel for the Company
incurred in connection with a registration pursuant to Section 3.2 or 3.3 shall
be borne by the Company. Each Holder whose shares are being sold will bear, pro
rata, underwriters' discounts and brokerage and other commissions, fees and
disbursements of its own counsel and all of its other expenses of such
registration, offering and sale.

         3.7      Underwriting Requirements. In connection with any registration
of Registrable Securities under this Agreement, the Holders whose shares are
being sold shall, if requested by the Company or the underwriters, enter into an
underwriting agreement with such underwriters for such offering, such agreement
to contain such terms and provisions as are customarily contained in
underwriting agreements with respect to secondary distributions, including,
without limitation,


                                       25

provisions relating to indemnification and contribution. The Holders on whose
behalf Registrable Securities are to be distributed shall also complete and
execute all questionnaires, powers of attorney and/or other documents required
under the terms of such underwriting agreement.

         3.8      Indemnification. In the event any Registrable Securities are
included in a registration statement pursuant to this Article III:

                  (a)      To the fullest extent permitted by law, the Company
will indemnify and hold harmless each Holder joining in a registration and its
directors and officers, any underwriter (as defined in the Securities Act) for
it, and each Person, if any, who controls such Holder or such underwriter within
the meaning of the Securities Act, from and against any losses, claims, damages,
expenses (including reasonable attorneys' fees and expenses and reasonable costs
of investigation) or liabilities, joint or several, to which they or any of them
may become subject under the Securities Act or otherwise, insofar as such
losses, claims, damages, expenses or liabilities (or actions or proceedings,
whether commenced or threatened, in respect thereof) arise out of or are based
on any untrue or alleged untrue statement of any material fact contained in such
registration statement including any preliminary prospectus or final prospectus
contained therein or any amendments or supplements thereto, or arise out of or
are based upon the omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements made therein
not misleading in light of the circumstances under which they were made,
provided that the indemnity agreement contained in this Section 3.8(a) shall not
apply to amounts paid in settlement of any such loss, claim, damage, liability
or action if such settlement is effected without the consent of the Company
(which consent shall not be unreasonably withheld), nor shall the Company be
liable for any such loss, claim, damage, liability or action to the extent that
it arises out of or is based upon (i) an untrue statement or omission made in
connection with such registration statement, preliminary prospectus, final
prospectus or amendments or supplements thereto in reliance upon and in
conformity with written information furnished by such Holder, underwriter or
control person to the Company specifically for inclusion in the Registration
Statement in connection with such registration, or (ii) such Holder's failure to
deliver a copy of the registration statement or prospectus or any amendments or
supplements thereto after the Company has furnished such Holder with a
sufficient number of copies of the same. Such indemnity shall remain in full
force and effect regardless of any investigation made by or on behalf of such
Holder, underwriter or control person and shall survive the transfer of such
securities by such Holder.

                  (b)      To the fullest extent permitted by law, each Holder
joining in a registration shall indemnify and hold harmless the Company, each of
its directors, each of its officers who has signed the registration statement,
each Person, if any, who controls the Company within the meaning of the
Securities Act, and each agent and any underwriter for the Company and any
Person who controls any such agent or underwriter and each other Holder and any
Person who controls such Holder (within the meaning of the Securities Act)
against any losses, claims, damages, expenses (including reasonable attorney's
fees and expenses and reasonable costs of investigation) or liabilities to which
the Company or any such director, officer, control person, agent, underwriter or
other Holder may become subject, under the Securities Act or otherwise, insofar
as such losses, claims, damages or liabilities (or actions or proceedings,
whether commenced or threatened, in respect thereof) arise out of or are based
upon an untrue statement of any material fact contained in such


                                       26

registration statement, including any preliminary prospectus or final prospectus
contained therein or any amendments or supplements thereto, or arise out of or
are based upon the omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading, in
each case to the extent that such untrue statement or omission was made in such
registration statement, preliminary or final prospectus, or amendments or
supplements thereto, in reliance upon and in conformity with written information
furnished by such Holder in connection with such registration, provided that the
indemnity agreement contained in this Section 3.8(b) shall not apply to amounts
paid in settlements effected without the consent of such Holder (which consent
shall not be unreasonably withheld). Such indemnity shall remain in full force
and effect regardless of any investigation made by or on behalf of the Company
or any such director, officer, Holder, underwriter or control person and shall
survive the transfer of such securities by such Holder.

                  (c)      Any Person seeking indemnification under this Section
3.8 will (i) give prompt written notice to the indemnifying party of any claim
with respect to which it seeks indemnification, but the failure to give such
notice will not affect the right to indemnification hereunder, except to the
extent the indemnifying party is actually prejudiced by such failure and (ii)
unless in such indemnified party's reasonable judgment a conflict of interest
may exist between such indemnified and indemnifying parties with respect to such
claim, permit such indemnifying party, and other indemnifying parties similarly
situated, jointly to assume the defense of such claim with counsel reasonably
satisfactory to the parties. In the event that the indemnifying parties cannot
mutually agree as to the selection of counsel, each indemnifying party may
retain separate counsel to act on its behalf and at its expense. The indemnified
party shall in all events be entitled to participate in such defense at its
expense through its own counsel. If such defense is not assumed by the
indemnifying party, the indemnifying party will not be subject to any liability
for any settlement made without its consent (but such consent will not be
unreasonably withheld). No indemnifying party will consent to entry of any
judgment or enter into any settlement which does not include as an unconditional
term thereof the giving by the claimant or plaintiff to such indemnified party
of a release from all liability in respect of such claim or litigation. An
indemnifying party who is not entitled to, or elects not to, assume the defense
of a claim will not be obligated to pay the fees and expenses of more than one
counsel for all parties indemnified by such indemnifying party with respect to
such claim.

                  (d)      If for any reason the foregoing indemnification is
unavailable to any party or insufficient to hold it harmless as and to the
extent contemplated by the preceding paragraphs of this Section 3.8, then each
indemnifying party shall contribute to the amount paid or payable by the
indemnified party as a result of such loss, claim, damage expense or liability
in such proportion as is appropriate to reflect the relative benefits received
by the indemnifying party, on the one hand, and the applicable indemnified
party, as the case may be, on the other hand, and also the relative fault of the
indemnifying party and any applicable indemnified party, as the case may be, as
well as any other relevant equitable considerations. 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 or entity who
was not guilty of such fraudulent misrepresentation.

underwriter of the initial Public Offering on behalf of the Company of its
Common Stock, or by the managing underwriter


                                       27

of a Public Offering for which Registrable Securities of any Holders have been
registered, all Holders (in the case of such initial Public Offering) or such
participating Holders (in the case of such other Public Offering) shall not sell

Holders (other than pursuant to Permitted Transfers, pursuant to Section 2.3 and
other than those Registrable Securities included in the registration) during
such period following the effective date of such registration as is usual and
customary at such time in similar public offerings of similar securities.

all action, including, but not limited to, such Stockholder's voting, or
executing proxies or written consents with respect to, the Voting Stock at the
time held by such Stockholder as may be from time to time requested by holders
of a majority of the Common Stock Equivalents at the time held by the JWC
Holders (or the JWC Representative) so that the Board of Directors shall consist
of such number of directors, no less than seven and up to a maximum of ten
directors, as may be from time to time designated by the holders of a majority
of the Common Stock Equivalents at the time held by the JWC Holders (or the JWC
Representative).

                  (b)      The Company and each of the Stockholders shall take
all action, including, but not limited to, such Stockholder's voting, or
executing proxies or written consents with respect to, the Voting Stock at the
time held by such Stockholder as may be from time to time requested by holders
of a majority of the Common Stock Equivalents at the time held by the JWC
Holders (or the JWC Representative) so that the Board of Directors shall include

shall also be entitled to require that any member of the Board of Directors so
designated pursuant to this Section 4.1(b) be removed or replaced by another
designee of the holders of a majority of the Common Stock Equivalents at the
time held by the JWC Holders (or the JWC Representative), in which event the

time to time requested by the holders of a majority of the Common Stock
Equivalents at the time held by the Original Halifax Holders and their Permitted
Transferees (other than the JWC Holders and Management Holders) or on their
behalf by the Halifax Representative, so that the Board of Directors shall
include two directors designated by the holders


                                       28

of a majority of the Common Stock Equivalents held by the Original Halifax
Holders and their Permitted Transferees (other than the JWC Holders and
Management Holders) or on their behalf by the Halifax Representative which
directors (the "Halifax Directors") shall initially be David Dupree and Kenneth

Holders and their Permitted Transferees (other than the JWC Holders and
Management Holders) shall be entitled to designate pursuant to this Section
4.1(c) shall be permanently reduced from two to one director at such time as the
Original Halifax Holders and their Permitted Transferees (other than the JWC
Holders and Management Holders) hold less than 50% of the Common Stock
Equivalents held by the Original Halifax Holders as of the date of this
Agreement; provided further, that the number of Halifax Directors designated
pursuant to this Section 4.1(c) shall be permanently reduced to zero directors
at such time as the Original Halifax Holders and their Permitted Transferees
(other than the JWC Holders and Management Holders) hold less than 5% of the
Common Stock Equivalents outstanding. The holders of a majority of the Common
Stock Equivalents at the time held by the Original Halifax Holders and their
Permitted Transferees (other than the JWC Holders and Management Holders) or on
their behalf by the Halifax Representative shall also be entitled to require
that any director so designated pursuant to this Section 4.1(c) be removed or
replaced by another designee of the holders of the majority of the Common Stock
Equivalents at the time held by the Original Halifax Holders and their Permitted
Transferees (other than the JWC Holders and Management Holders) or on their
behalf by the Halifax Representative, in which event the Company and each
Stockholder shall take all action, including, but not limited to, such
Stockholder's voting, or executing proxies or written consents with respect to,
the Voting Stock at the time held by such Stockholder as may be necessary to
effect such removal or replacement.

         4.2      Rights of the Halifax Directors.

                  (a)      Notwithstanding that no vote may be required, or that
a lesser percentage vote may be specified in the certificate of incorporation or
by-laws of the Company, the Company shall not take, and no Stockholder shall
cause the Company to take, any of the following actions without the affirmative
vote of a majority of the Board of Directors, which majority vote shall include
the affirmative vote of the directors, if any, designated pursuant to Section
4.1(c) (the "HALIFAX AFFIRMATIVE BOARD VOTE"):

                           (i)      the redemption, purchase or other

terms of securities of the Company created after the date hereof which require
such declaration, payment or other distribution;


                                       29

                           (iii)    the termination of the Chief Executive

current employment agreement with the Company or one of its subsidiaries);

                           (iv)     any issuance of Common Stock Equivalents in
connection with a transaction or series of related transactions involving an
acquisition of the equity or assets of a Third Party which results in an

                           (v)      the entering into of any transaction or

                           (vi)     any significant change in the nature of the
Company's business as of the date hereof.

Notwithstanding anything to the contrary herein, (x) the Halifax Affirmative
Board Vote shall no longer be necessary with respect to the matters set forth in
clauses (iii) and (iv) above at such time as the Original Halifax Holders and
their Permitted Transferees (other than the JWC Holders and Management Holders)
hold less than 50% of the Common Stock Equivalents held by the Original Halifax
Holders as of the date of this Agreement and (y) the provisions of this Section

less than 5% of the Common Stock Equivalents.

contrary herein, the rights of the Original Halifax Holders and their Permitted
Transferees (other than the JWC Holders and Management Holders) and the Halifax
Directors under Section 4.1 and 4.2, respectively, may only be exercised by the
Original Halifax Holders and their Permitted Transferees (other than the JWC
Holders and Management Holders) and Halifax Directors, respectively, and may not
be transferred or assigned in connection with any other Transfer of Subject
Securities or otherwise.

                                Preemptive Rights

         5.1      Rights to Subscribe for Securities.

                  (a)      Except in the case of Excluded Securities (as defined
in Section 5.1(e)), the Company shall not, and shall cause its Subsidiaries not
to, issue or sell any Common Stock Equivalent, unless the Company shall have
first offered or caused such Subsidiary to offer (the


                                       30

"PREEMPTIVE OFFER") to sell such Common Stock Equivalents to the JWC Holders and
Halifax Holders (the "OFFERED SECURITIES") by delivery to such JWC Holders and
Halifax Holders of written notice of such offer stating that the Company or such
Subsidiary proposes to sell such Offered Securities, the number or amount of the
Offered Securities proposed to be sold, the proposed purchase price therefor and
any other terms and conditions of such offer. The Preemptive Offer shall by its
terms remain open and irrevocable for a period of 10 Business Days from the date
it is received from the Company (the "PREEMPTIVE OFFER PERIOD").

                  (b)      Each JWC Holder and Halifax Holder shall have the
option, exercisable at any time during the Preemptive Offer Period by delivering
written notice to the Company or such Subsidiary (a "PREEMPTIVE OFFER ACCEPTANCE
NOTICE"), to subscribe for the number or amount of such Offered Securities that
would permit such JWC Holders and Halifax Holders to maintain its Offeree
Percentage as it existed immediately prior to such issuance, sale or exchange.
The Company or such Subsidiary shall notify each JWC Holder and Halifax Holder
within five days following the expiration of the Preemptive Offer Period of the
number or amount of Offered Securities which such JWC Holder and Halifax Holder
has subscribed to purchase.

                  (c)      If Preemptive Offer Acceptance Notices are not given
by the JWC Holders and Halifax Holders for all of the Offered Securities, the
Company or such Subsidiary making such Preemptive Offer shall have 60 days from

Offered Securities as to which Preemptive Offer Acceptances Notices have not
been given by the JWC Holders and Halifax Holders (the "Refused Securities") to
any other Persons upon the terms and conditions including price, which are no
more favorable, in the aggregate, to such other Persons or less favorable to the
Company or such Subsidiary than those set forth in the Preemptive Offer.

                  (d)      Upon the closing, which shall include full payment to
the Company or such Subsidiary, of the sale to such other Persons of all the
Refused Securities, such JWC Holders and Halifax Holders shall purchase from the
Company or such Subsidiary, and the Company or such Subsidiary shall sell to
such JWC Holders and Halifax Holders, the Offered Securities with respect to
which Preemptive Offer Acceptance Notices were delivered by such JWC Holders and
Halifax Holders, at the terms specified in the Preemptive Offer.

                  (e)      The rights of the JWC Holders and Halifax Holders
under this Section 5.1 shall not apply to the following securities (the

Subsidiaries or upon the exercise or conversion of options or other Common Stock
Equivalents issued to employees and consultants of the Company or its
Subsidiaries;

                           (ii)     any Common Stock Equivalents and other

                                       31

                           (iii)    any Common Stock Equivalents issued to any
         individual or entity which, in connection with the issuance of Common
         Stock Equivalents to such entity, simultaneously enters into a
         significant business transaction with the Company which is directly
         related to the Company's business;

                           (iv)     any Common Stock Equivalents issued as part
         of a Public Offering or any effective registration statement under the

                           (v)      any Common Stock Equivalents issued to the
         Company or a Subsidiary.

                                  ARTICLE VI

                     Certain Miscellaneous Other Provisions

         6.1      Remedies. Each of the parties hereto acknowledges and agrees
that no remedy at law would be adequate in the event of any breach of this
Agreement. Accordingly, if any dispute arises concerning the sale or other
disposition of any of the securities of the Company subject to this Agreement or
concerning any other provisions hereof or the obligations of the parties
hereunder, each party hereto agrees that, in addition to any other remedy to
which they may be entitled at law or in equity, the other parties hereto shall
be entitled to a decree of specific performance to enforce this Agreement
(without bond or other security being required unless the party seeking such
remedy fails to demonstrate to an appropriate court having jurisdiction that
such party has a likelihood of success on the merits), and each party hereto
waives the defense in any action or proceeding brought to enforce this Agreement
that there exists an adequate remedy at law. Such remedies shall be cumulative
and non-exclusive and shall be in addition to any other rights and remedies the
parties may have under this Agreement or otherwise.

         6.2      Entire Agreement; Amendment; Termination.

                  (a)      This Agreement sets forth the entire understanding of
the parties, and supersedes all prior agreements and all other arrangements and
communications, whether oral or written, with respect to the subject matter
hereof.

                  (b)      The Schedule of Stockholders may be amended in
writing by the Company to reflect changes in the composition of the Stockholders
and changes in their addresses or telecopy numbers that may occur from time to
time as a result of Permitted Transfers, Transfers permitted under Article II
hereof or any new issuance by the Company of Common Stock or Common Stock
Equivalents; provided, however, that no new issuance of Common Stock or Common
Stock Equivalents shall be effective unless and until the Person receiving such
securities (if not already a party hereto in such capacity) executes and
delivers to the Company an executed Joinder Agreement in accordance with Section
2.13 hereof. Amendments to the Schedule of Stockholders reflecting Permitted
Transfers or Transfers permitted under Article II hereof shall become effective
when the amended Schedule of Stockholders, and a copy of a Joinder Agreement as
executed by any new transferee in accordance with Section 2.13, are filed with
the Company.


                                       32

                  (c)      Any other amendment to this Agreement shall be in
writing and shall require the written consent of (a) the Company, (b) either the
JWC Representative or the holders of a majority of Common Stock Equivalents at
the time held by the JWC Holders, and, (c) if adverse to the interests of a
particular Stockholder or Stockholder Group, then the consent of each particular
Stockholder or the holders of a majority of the Common Stock Equivalents at the
time held by such particular Stockholder Group, as the case may be, to whose
interest such amendment is adverse.

                  (d)      Notwithstanding the foregoing provisions of this
Section 6.2, this Agreement may be terminated at any time upon the written
consent of (i) the Company and (ii) the holders of a majority of the Common
Stock Equivalents at the time held by the Management Holders and (iii) the
holders of a majority of the Common Stock Equivalents at the time held by the
Halifax Holders and (iv) the holders of a majority of the Common Stock
Equivalents at the time held by the JWC Holders (or the JWC Representative),
each voting separately as a group.

         6.3      Severability. Any term or provision of this Agreement that is
invalid or unenforceable in any situation in any jurisdiction shall not affect
the validity or enforceability of the remaining terms and provisions hereof or
the validity or enforceability of the offending term or provision in any other
situation or in any other jurisdiction. If the final judgment of a court of
competent jurisdiction declares that any term or provision hereof is invalid or
unenforceable, the parties agree that the body making the determination of
invalidity or unenforceability shall have the power to reduce the scope,
duration or area of the term or provision, to delete specific words or phrases,
or to replace any invalid or unenforceable term or provision with a term or
provision that is valid and enforceable and that comes closest to expressing the
intention of the invalid or unenforceable term or provision, and this Agreement
shall be enforceable as so modified after the expiration of the time within
which the judgment may be appealed.

         6.4      Notices. All notices, consents and other communications

         6.9      Halifax Representative. Each Halifax Holder hereby designates
and appoints (and each Permitted Transferee of each such Halifax Holder shall be

coupled with an interest and shall survive the death or incapacity of such
Person. Each such Person hereby authorizes (and each Permitted Transferee shall
be deemed to have authorized) the other parties hereto to disregard any notice
or other action taken by such Person pursuant to this Agreement except for the
Halifax Representative. The other parties hereto are and will be entitled to
rely on any action so taken or any notice given by the Halifax Representative
and are and will be entitled and authorized to give notices only to the Halifax
