          2. Incidental Registrations. (a) Right to Include Registrable
Securities. If the Company at any time after the IPO Date proposes to register
shares of its Common Stock under the Securities Act (other than (i) a
registration statement filed by the Company in connection with the IPO, (ii) a
registration statement on Form S-4 or S-8, or any successor or other forms
promulgated for similar purposes, or (iii) a registration statement with respect
to corporate reorganizations or other transactions under Rule 145 of the
Securities Act or any successor rule promulgated for similar purposes), whether
or not for sale for its own account (including, without limitation, any
registration effected pursuant to Section 3 hereof), in a manner which would
permit registration of Registrable Securities for sale to the public under the
Securities Act, it will, at each such time, give prompt written notice to all
Holders of Registrable Securities of its intention to do so and will afford each
such Holder an opportunity to include in such registration all or part of the
Registrable Securities held by such Holder. Upon the written request of any such
Holder made within fifteen (15) days after the receipt of any such notice (which
request shall specify the Registrable Securities intended to be disposed of by
such Holder), the Company will, subject to Section 2(c) below, 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 the Holders to the extent requisite to permit the disposition of the
Registrable Securities so to be registered; provided that (i) if, at any time
after giving written notice of its intention to register any securities 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
proceed with the proposed registration of the securities to be sold by it, the
Company may, at its election, give written notice of such determination to each
Holder of Registrable Securities and, thereupon, shall be relieved of its
obligation to register any Registrable Securities in connection with such
registration, and (ii) if such registration involves an underwritten offering,
all Holders of Registrable Securities requesting to be included in the Company's
registration must sell their Registrable Securities to the underwriters selected
by the Company on the same terms and conditions as apply to the Company
(including entering into an underwriting agreement in customary form with the
underwriter or underwriters selected for such offering by the Company), as may
be customary or appropriate in combined primary and secondary offerings. If a
registration requested pursuant to this Section 2(a) involves an underwritten
public offering, any Holder of Registrable Securities requesting to be included
in such registration may elect, in writing at least ten (10) days prior to the
effective date of the registration statement filed in connection with such
registration, not to register such securities in connection with such
registration.

          (b) Expenses. The Company will pay all Registration Expenses incurred
in connection with each registration of Registrable Securities pursuant to this
Section 2. All Selling Expenses applicable to Registrable Securities sold by
Holders incurred in connection with each registration pursuant to this Section 2
shall be borne by the Holders of the Registrable Securities so registered pro
rata based on the number of securities so registered.

                                       3

          (c) Priority in Incidental Registrations. If a registration pursuant
to this Section 2 involves an underwritten offering and the managing underwriter
determines in good faith that marketing factors require a limitation on the
number of securities to be underwritten, the number of securities that may be
included will be limited to the number of securities that, in the opinion of
such underwriter, should be included and the securities to be included in the
registration shall be allocated first, to the Company, and second, to all
requesting Holders on the basis of the relative number of Registrable Securities
then held by each such Holder (provided that any securities thereby allocated to
any such Holder that exceed such Holder's request will be reallocated among the
remaining requesting Holders in like manner).

          3. Registration on Request. (a) At anytime, after the date that is six
(6) months after the IPO Date, upon the written request of (i) the Holder or
Holders of a majority of the Registrable Securities held by the Carlyle Holders
(the "Carlyle Demand Party") requesting that the Company effect the registration
under the Securities Act of all or part of the Registrable Securities held by
the Carlyle Holders (a "Carlyle Demand"), or (ii) Executive requesting that the
Company effect the registration under the Securities Act of all or part of the
Registrable Securities held by the Executive Holders (an "Executive Demand"; for
purposes of this Section 3, "Demand Party" shall mean the Carlyle Demand Party,
in the case of a Carlyle Demand, or Executive, in the case of an Executive
Demand), and specifying the amount and intended method of disposition thereof,
the Company thereupon will, as expeditiously as possible, subject to the
limitations of this Section 3, use its reasonable best efforts to effect the
registration under the Securities Act of (i) such Registrable Securities which
the Company has been so requested to register by the Demand Party, (ii) such
Registrable Securities which the Company has been requested to register by other
Holders of Registered Securities exercising their rights under Section 2 hereof
with respect to such registration and (iii) any shares of Common Stock that the
Company desires to include in such registration, in each case, to the extent
necessary to permit the disposition (in accordance with the intended method
thereof as aforesaid) of the Registrable Securities so to be registered;
provided that the Carlyle Demand Party shall not be entitled to make a Carlyle
Demand at any time that the Carlyle Holders hold less than five percent (5%) of
the Registrable Securities then outstanding; provided further that Executive
shall not be entitled to make an Executive Demand at any time that the Executive
Holders hold less than five percent (5%) of the Registrable Securities then
outstanding. If any registration effected pursuant to this Section 3 is intended
to involve an underwritten offering, the managing underwriter for such offering
shall be selected by the Company (and shall be reasonably acceptable to the
Demand Party).

          (b) Expenses. The Company will pay all Registration Expenses incurred
in connection with each registration of Registrable Securities pursuant to this
Section 3. All Selling Expenses applicable to Registrable Securities sold by
Holders incurred in connection with each registration pursuant to this Section 3
shall be borne by the Holders of the Registrable Securities so registered pro
rata based on the number of securities so registered.

          (c) Priority in Requested Registrations. If a requested registration
pursuant to this Section 3 involves an underwritten offering and the managing
underwriter determines in good faith that marketing factors require a limitation
on the number of securities to be underwritten, the number of securities that
may be included will be limited to the number of securities that, in the opinion
of such managing underwriter, should be included and the

                                       4

<PAGE>

securities to be included in the registration shall be allocated first, to the
Demand Party and the other Holders requesting inclusion of Registrable
Securities in such registration on the basis of the relative number of
Registrable Securities then held by each such Holder (provided that any
securities thereby allocated to any such Holder that exceed such Holder's
request will be reallocated among the remaining Holders in like manner), and
second, to the Company.

          (d) Limitation on Registration on Request. Notwithstanding anything in
this Section 3 to the contrary, (i) the Company shall not be obligated to take
any action to effect any registration pursuant to this Section 3 if the Company
has previously effected a number of registrations upon the request of a Demand
Party pursuant to this Section 3 equaling or exceeding four (4) registrations,
in the case of the Carlyle Demand Party, and three (3) registrations, in the
case of Executive and (ii) the Company shall not be obligated to effect more
than three (3) registrations pursuant to this Section 3 in any year; provided,
however, that no registration effected pursuant to this Section 3 will count
towards the foregoing numerical limits on the number of registrations that may
be requested by a Demand Party pursuant to this Section 3 if the Registrable
Securities proposed to be sold by such Demand Party in such registration are cut
back pursuant to Section 3(c).

          (e) Postponements in Requested Registrations. (i) If the Company shall
at any time furnish to the Demand Party a certificate signed by its chairman of
the board, chief executive officer, president or any other of its authorized
officers stating that the filing of such registration statement would be
materially detrimental to the Company or its stockholders, the Company may
postpone the filing of a registration statement required by this Section 3 for
up to one hundred eighty (180) days and (ii) if the Board of Directors of the
Company determines in its good faith judgment that the registration and offering
otherwise required by this Section 3 would have an adverse effect on a then
contemplated public offering of the Company's Common Stock, the Company may
postpone the filing of a registration statement required by this Section 3,
during the period starting with the sixtieth (60th) day immediately preceding
the date of the anticipated filing of, and ending on a date one hundred eighty
(180) days following the effective date of, the registration statement relating
to such other public offering. The Company shall promptly give the Demand Party
requesting registration thereof pursuant to this Section 3 written notice of any
postponement made in accordance with the preceding sentence.

          4. Registration Procedures. If and whenever the Company is required to
use its reasonable best efforts to effect or cause the registration of any
Registrable Securities under the Securities Act as provided in this Agreement,
the Company will (to the extent not relieved of such obligation as provided in
Section 2 hereof), as expeditiously as possible:

          (i) prepare and, in any event within sixty (60) days after the end of
     the period within which a request for registration may be given to the
     Company pursuant to Section 2 or 3, file with the SEC a registration
     statement with respect to such Registrable Securities and use its
     reasonable best efforts to cause such registration statement to become
     effective and, upon the request of the Holders of a majority of the
     Registrable Securities registered thereunder, keep such Registration
     Statement effective for up to one hundred eighty (180) days or, if earlier,
     until the Holder or Holders have completed the distribution described in
     the registration statement related thereto;

                                       5

<PAGE>

          (ii) prepare and file with the SEC such amendments and supplements to
     such registration statement and the prospectus used in connection therewith
     as may be necessary to keep such registration statement effective for the
     period set forth in paragraph (i) above and to comply with the provisions
     of the Securities Act, the Exchange Act and the rules and regulations of
     the SEC thereunder with respect to the disposition of all securities
     covered by such registration statement during such period in accordance
     with the intended methods of disposition by the seller or sellers thereof
     set forth in such registration statement;

          (iii) furnish to each seller of such Registrable Securities such
     number of copies of the prospectus included in such registration statement
     (including each preliminary prospectus and summary prospectus), in
     conformity with the requirements of the Securities Act, and such other
     documents as such seller may reasonably request in order to facilitate the
     disposition of the Registrable Securities by such seller;

          (iv) use its reasonable best efforts to register or qualify such
     Registrable Securities covered by such registration under such other
     securities or blue sky laws in such jurisdictions as each seller shall
     reasonably request, except that the Company shall not for any such purpose
     be required to qualify generally to do business as a foreign corporation in
     any jurisdiction where, but for the requirements of this clause (iv), it
     would not be obligated to be so qualified, to subject itself to taxation in
     any such jurisdiction or to consent to general service of process in any
     such jurisdiction;

          (v) notify each seller of any 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 within the appropriate
     period mentioned in clause (i) of this Section 4, of the Company's becoming
     aware that the prospectus included in such registration statement, as then
     in effect, includes an untrue statement of a material fact or omits 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
     then existing;

          (vi) use its reasonable best efforts to list such Registrable
     Securities on any securities exchange on which the Common Stock is then
     listed if such Registrable Securities are not already so listed and if such
     listing is then permitted under the rules of such exchange;

          (vii) in the event of an underwritten public offering, enter into an
     underwriting agreement in usual and customary form with the managing
     underwriter(s) of such offering;

          (viii) in the event of an underwritten public offering, use its
     reasonable best efforts to furnish, on the date that such Registrable
     Securities are delivered to the underwriters for sale, a "cold comfort"
     letter from the Company's independent public accounts in form and substance
     as is customarily given by independent public accountants to underwriters
     in an underwritten public offering;

                                       6

<PAGE>

          (ix) in the event of an underwritten public offering, use its
     reasonable best efforts to furnish, on the date that such Registrable
     Securities are delivered to the underwriters for sale, an opinion of
     counsel for the Company, dated as of such date, in form and substance as is
     customarily given to underwriters in an underwritten public offering; and

          (x) cooperate and assist with any filings required to be made with the
     NASD.

          The Company may require each seller of Registrable Securities as to
which any registration is being effected to furnish the Company with such
information regarding such seller and pertinent to the disclosure requirements
relating to the registration and the distribution of such securities as the
Company may from time to time reasonably request.

          Each Holder of Registrable Securities agrees that, upon receipt of any
notice from the Company of the happening of any event of the kind described in
clause (v) of this Section 4, such Holder will forthwith discontinue disposition
of Registrable Securities pursuant to the registration statement covering such
Registrable Securities until such Holder's receipt of the copies of the
supplemented or amended prospectus contemplated by clause (v) of this Section 4,
and, if so directed by the Company, such Holder will deliver to the Company (at
the Company's expense) all copies of the prospectus covering such Registrable
Securities current at the time of receipt of such notice. In the event the
Company shall give any such notice, the period mentioned in clause (i) of this
Section 4 shall be extended by the number of days during the period from and
including the date of the giving of such notice pursuant to clause (v) of this
Section 4 and to and including the date when each seller of Registrable
Securities covered by such registration statement shall have received the copies
of the supplemented or amended prospectus contemplated by clause (v) of this
Section 4.

          5. Indemnification. (a) Indemnification by the Company. In the event
of any registration of any securities of the Company under the Securities Act
pursuant to Sections 2 or 3 hereof, the Company will indemnify and hold
harmless, to the extent permitted by law, the seller of any Registrable
Securities covered by such registration statement, each affiliate of such seller
and their respective directors and officers, stockholders, members or general
and limited partners (including any director, officer, affiliate, employee,
agent and controlling Person of any of the foregoing), each other Person who
participates as an underwriter in the offering or sale of such securities and
each other Person, if any, who controls such seller or any such underwriter
within the meaning of the Securities Act, against any and all losses, claims,
damages or liabilities, joint or several, and expenses (including reasonable
attorney's fees and reasonable expenses of investigation) to which such
indemnified party may become subject under the Securities Act, common law or
otherwise, insofar as such losses, claims, damages or liabilities (or actions or
proceedings in respect thereof, whether or not such indemnified party is a party
thereto) arise out of or are based upon (a) any untrue statement or alleged
untrue statement of any material fact contained in any registration statement
under which such securities were registered under the Securities Act, any
preliminary, final or summary prospectus contained therein, or any amendment or
supplement thereto, or (b) any omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein (in the case of a prospectus, in light of the circumstances under which
they were made) not misleading, and the Company will reimburse such indemnified
party for any legal or any

                                       7

<PAGE>

other expenses reasonably incurred by it in connection with investigating or
defending against any such loss, claim, liability, action or proceeding;
provided that the Company shall not be liable to any indemnified party in any
such case to the extent that any such loss, claim, damage, liability (or action
or proceeding in respect thereof) or expense arises out of or is based upon any
untrue statement or alleged untrue statement or omission or alleged omission
made in such registration statement or amendment or supplement thereto or in any
such preliminary, final or summary prospectus or a document incorporated by
reference into any of the foregoing in reliance upon and in conformity with
written information furnished to the Company by such seller specifically for use
in the preparation thereof; and provided, further, that the Company will not be
liable to any indemnified person under the indemnity agreement in this Section
5(a) with respect to any preliminary prospectus or the final prospectus or the
final prospectus as amended or supplemented, as the case may be, to the extent
that any such loss, claim, damage or liability of such indemnified person
results from the fact that an underwriter sold Registrable Securities to a
person to whom there was not sent or given, at or prior to the written
confirmation of such sale, a copy of the final prospectus or of the final
prospectus as then amended or supplemented, whichever is most recent, if the
Company has previously furnished copies thereof to such underwriter.

          (b) Indemnification by the Seller. In the event of any registration of
any securities of the Company under the Securities Act pursuant to Sections 2 or
3 hereof, each seller of Registrable Securities included in such registration
will indemnify and hold harmless (in the same manner and to the same extent as
set forth in Section 5(a)) the Company, each affiliate of the Company and their
respective directors, officers, stockholders, members or general and limited
partners (including any director, officer, affiliate, employee, agent and
controlling Person of any of the foregoing), each other Person who participates
as an underwriter in the offering or sale of such securities and all other
sellers of Registrable Securities covered by such registration statement, each
affiliate of such seller and their respective directors, officers, stockholders,
members or general and limited partners (including any director, officer,
affiliate, employee, agent and controlling person of any of the foregoing) and
each other Person, if any, who controls the Company or such underwriter or such
seller within the meaning of the Securities Act, with respect to any untrue
statement or alleged untrue statement in or omission or alleged omission from
such registration statement, any preliminary, final or summary prospectus
contained therein, or any amendment or supplement, to the extent that such
untrue statement or alleged untrue statement or omission or alleged omission was
made in reliance upon and in conformity with written information furnished to
the Company by such seller specifically for use in the preparation of such
registration statement, preliminary, final or summary prospectus or amendment or
supplement, or a document incorporated by reference into any of the foregoing.
In no event shall the liability of any selling Holder of Registrable Securities
hereunder be greater in amount than the dollar amount of the net proceeds
received by such Holder upon the sale of the Registrable Securities giving rise
to such indemnification obligation.

          (c) Notices of Claims, Etc. Promptly after receipt by an indemnified
party hereunder of written notice of the commencement of any action or
proceeding with respect to which a claim for indemnification may be made
pursuant to this Section 5, such indemnified party will, if a claim in respect
thereof is to be made against an indemnifying party, give written notice to the
latter of the commencement of such action; provided that the failure of the
indemnified party to give notice as provided herein shall not relieve the
indemnifying party of its

                                       8

<PAGE>

obligations under this Section 5, except to the extent that the indemnifying
party is actually prejudiced by such failure to give notice. In case any such
action is brought against an indemnified party, the indemnifying party will be
entitled to participate in and to assume the defense thereof, with counsel
reasonably satisfactory to such indemnified party. 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
to such claim or litigation.

          (d) Contribution. If the indemnification provided for in this Section
5 from the indemnifying party is unavailable to an indemnified party hereunder
in respect of any losses, claims, damages, liabilities or expenses referred to
herein, then the 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, liabilities or expenses in such
proportion as is appropriate to reflect the relative fault of the indemnifying
party and such indemnified party in connection with the actions which resulted
in such losses, claims, damages, liabilities or expenses, as well as any other
relevant equitable considerations. The relative fault of such indemnifying party
and such indemnified party shall be determined by reference to, among other
things, whether any action in question, including any untrue or alleged untrue
statement of a material fact or omission or alleged omission to state a material
fact, has been made by, or relates to information supplied by, such indemnifying
party or indemnified parties, and the parties' relative intent, knowledge,
access to information and opportunity to correct or prevent such action. The
amount paid or payable by a party under this Section 5(d) as a result of the
losses, claims, damages, liabilities and expenses referred to above shall be
deemed to include any legal or other fees or expenses reasonably incurred by
such party in connection with any investigation or proceeding.

          The parties hereto agree that it would not be just and equitable if
contribution pursuant to this Section 5(d) 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.
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.

          6. Rule 144. With a view to making available the benefits of certain
rules and regulations of the SEC which may permit the sale of restricted
securities to the public without registration, the Company agrees to:

          (a) use its reasonable best efforts to make and keep public
information available as those terms are understood and defined in Rule 144
under the Securities Act ("Rule 144"), at all times from and after ninety (90)
days following the effective date of the IPO;

          (b) use its reasonable best efforts to file with the SEC in a timely
manner all reports and other documents required of the Company under the
Securities Act and the Exchange Act at any time after it has become subject to
such reporting requirements; and

          (c) so long as the Holder owns any Registrable Securities, furnish to
the Holder upon request, (x) a written statement by the Company as to the status
of its compliance

                                       9

<PAGE>

with the reporting requirements of Rule 144 (at any time from and after ninety
(90) days following the effective date of the IPO, and of the Securities Act and
the Exchange Act (at any time after it has become subject to such reporting
requirements), (y) a copy of the most recent annual or quarterly report of the
Company, and (z) such other reports and documents so filed as the Holder may
reasonably request in availing itself of any rule of regulation of the SEC
allowing the Holder to sell any such securities without registration.

          7. Selection of Counsel. In connection with any registration of
Registrable Securities pursuant to Sections 2 or 3 hereof, the Holders of a
majority of the Registrable Securities covered by any such registration may
select one counsel to represent all Holders of Registrable Securities covered by
such registration.

          8. Miscellaneous.

          (a) Holdback Agreement. If the Company effects any registration in
connection with an underwritten public offering (including the IPO) of the
Common Stock (whether pursuant to this Agreement or otherwise), each Holder of
Registrable Securities will, if requested by the Company, enter into an
agreement with the Company and the underwriter or underwriters of such offering
(in form reasonably acceptable to the Company) pursuant to which such Holder
will agree not to sell, make any short sale of, loan, grant any option for the
purchase of, or otherwise dispose of, including any sale pursuant to Rule 144
under the Securities Act, any equity securities of the Company, or of any
security convertible into or exchangeable or exercisable for any equity security
of the Company (in each case, other than as part of such underwritten public
offering), within seven days before, or ninety (90) days (or one hundred eighty
(180) days in the case of an IPO) after, the effective date of such
registration. The Company may impose stop - transfer instructions with respect
to the Registrable Securities subject to the foregoing restriction until the end
of said 180-day or 90-day period.

          (b) Amendments and Waivers. This Agreement may be amended and the
Company may take any action herein prohibited, or omit to perform any act herein
required to be performed by it, only if the Company shall have obtained the
written consent to such amendment, action or omission to act, of the Holders of
Registrable Securities that own, in the aggregate, at least fifty percent (50%)
of the Registrable Securities then outstanding and Executive (so long as
Executive holds more than five percent (5%) of the Registrable Securities then
outstanding); provided that any amendment, action or omission to act that would
disproportionately and adversely affect the rights of any Holder under this
Agreement shall also require the consent of such Holder. Each Holder of
Registrable Securities at the time or thereafter outstanding shall be bound by
any consent authorized by this Section 8(b), whether or not such Registrable
Securities shall have been marked to indicate such consent.

          (c) Successors, Assigns and Transferees. This Agreement shall not be
assigned; provided that (i) any Carlyle Holder may assign all or part of their
rights and obligations under this Agreement to any transferee who has acquired
Registrable Securities from any such Carlyle Holder to the extent that such
transfer does not violate the Stockholders Agreement and such transferee agrees
in writing to be bound by the terms of this Agreement and (ii) any Executive
Holder may assign all or part of his rights and obligations under this Agreement
to a transferee who has acquired Registrable Securities from such Executive
Holder

                                       10

<PAGE>

to the extent such transfer does not violate the Stockholders Agreement and such
transferee agrees in writing to be bound by the provisions of this Agreement;
provided further that, notwithstanding the foregoing, Executive may not transfer
his rights to request registration pursuant to Section 3 hereof, except that, in
the event of death or legal disability of Executive, such rights shall vest in
the executor or trustee that controls the Registrable Securities held by
Executive immediately prior to such death or legal disability. Subject to the
foregoing restrictions, this Agreement shall be binding upon and shall inure to
the benefit of the parties hereto and their successors and assigns.

                        SUNSHINE ACQUISITION CORPORATION

          This Service Provider Stockholders Agreement ("Agreement") is entered

Carlyle Stockholders") and the service providers that hold shares of Common
Stock (as defined below) or Vested Options (as defined below) that are or become
a party hereto from time to time by executing a supplemental signature page in
the form attached as Exhibit A hereto (each such holder and any Permitted
Transferee of such holder, individually, a "Service Provider Stockholder," and
collectively, the "Service Provider Stockholders"). Certain capitalized terms
used herein without definition have the meanings ascribed to them in Section 9
hereof.

                                    RECITALS:

          WHEREAS, on the date hereof, the Company acquired all of the
outstanding capital stock of SS&C Technologies, Inc., a Delaware corporation
("SS&C"), pursuant to that certain Agreement and Plan of Merger, dated as of
July 28, 2005, and amended as of August 25, 2005, by and among the Company,
Sunshine Merger Corporation, a Delaware corporation and wholly owned subsidiary

          WHEREAS, certain Service Provider Stockholders (a) hold shares of

(b) have been or may hereafter be issued shares of Common Stock pursuant to the
exercise by such Service Provider Stockholders of vested options to purchase

for vested options to purchase common stock of SS&C pursuant to the Merger
Agreement (the "Assumed Options") or (ii) may hereafter be issued pursuant to
any stock option plans or other employee benefit plans, in either case, now in
effect or hereafter adopted by the board of directors of the Company (the
"Board", and each director, a "Director") or pursuant to other arrangements
approved by the Board (the shares of Common Stock or other shares of capital
stock of the Company issued or that are hereafter issued to the Service Provider
Stockholders being collectively referred to as the "Restricted Shares" and,
together with the Vested Options, any other vested rights issued by the Company
to the Service Provider Stockholders to acquire Common Stock or capital stock of
the Company, the "Restricted Securities"); and

          WHEREAS, the Parties hereto desire to establish herein certain terms
and conditions upon which the Restricted Securities will be held, including
provisions restricting the transfer of such, and providing for other matters.

                                   AGREEMENT:

<PAGE>

          NOW, THEREFORE, in consideration of the foregoing and the mutual
agreements set forth herein, and other good and valuable consideration, the
receipt and adequacy of which are hereby acknowledged, the Parties hereto,
intending to be legally bound, hereby agree as follows:

Section 1. Restrictions on Transfer.

          Except for (i) Transfers effected by Service Provider Stockholders
pursuant to the exercise of Bring-Along Rights pursuant to Section 2 by the
Carlyle Stockholders or any Transfer effected in connection with a Company Sale
pursuant to Section 2; (ii) Transfers effected by Service Provider Stockholders
pursuant to the exercise of Tag-Along Rights pursuant to Section 3; (iii)
Transfers effected by Service Provider Stockholders pursuant to the Registration
Rights Agreement, dated as of the date hereof, by and among the Company, the
Initial Carlyle Stockholders, William C. Stone and the Service Provider
Stockholders; and (iv) any Permitted Transfer, no Service Provider Stockholder
shall Transfer any Restricted Securities without the prior written approval of a
majority of the members of the Board, which such majority shall include at least
one Director nominated by William C. Stone, for so long as he serves as the
Chief Executive Officer of the Company. Each Service Provider Stockholder
further agrees that, in connection with any Permitted Transfer, any Transfer
approved by the Board or any Transfer after the IPO, such Service Provider
Stockholder shall, if requested by the Company, deliver to the Company an
opinion of counsel, in form and substance reasonably satisfactory to the Company
and counsel for the Company, to the effect that such Transfer is not in
violation of this Agreement, the Securities Act of 1933, as amended, and the
rules and regulations promulgated thereunder (the "Securities Act"), or the
securities laws of any state. Any purported Transfer in violation of the
provisions of this Section 1 shall be null and void and shall have no force or
effect. It shall be a condition to any Permitted Transfer, any Transfer approved
by the Board (other than any Transfer pursuant to Rule 144 promulgated under the
Securities Act approved by the Board) or any Transfer after the IPO (other than
any Transfer pursuant to Rule 144 promulgated under the Securities Act) that the
transferee shall (i) agree to become a party to this Agreement as a Service
Provider Stockholder and (ii) execute a signature page in the form attached as
Exhibit A hereto acknowledging that such transferee agrees to be bound by the
terms hereof.

Section 2. Bring-Along Rights.

          (a) If on or after the earlier of (i) the second anniversary of the
date hereof and (ii) the date that William C. Stone ceases to be Chief Executive
Officer of the Company, one or more Carlyle Stockholders, in one transaction or
a series of related transactions, propose to Transfer fifty percent (50%) or
more of the outstanding shares of Common Stock to one or more Persons other than
Affiliates, partners, members or stockholders of the Carlyle Stockholders (each
such Person, a "Third Party Purchaser"), then such Carlyle Stockholder(s) shall
have the right (a "Bring-Along Right") upon delivery of the Bring-Along Notice
(defined below), but not the obligation (subject to Section 3 hereof), to
require all, but not less than all, of the Service Provider Stockholders to
tender for purchase to the Third Party Purchaser(s), on the same terms and
conditions as apply to the Carlyle Stockholder(s) (provided, however, that (i)
in the event

                                       2

<PAGE>

that the Carlyle Stockholder(s) are granted the right to appoint any director or
directors of any Person in connection with such Transfer, the Carlyle
Stockholder(s) shall be entitled to designate such member or members of the
board of directors of such Person and (ii) in the event that any portion of the
consideration payable to the Carlyle Stockholder(s) in connection with such
Transfer is in a form other than cash, and the Third Party Purchaser notifies
the Carlyle Stockholders that the Third Party Purchaser desires to provide to
the Service Provider Stockholders consideration solely in cash in lieu of the
non-cash consideration to be provided to the Carlyle Stockholder(s), then, at
the election of the Carlyle Stockholder(s), the consideration payable to such
Service Provider Stockholders in connection with such Transfer may consist
solely of cash, in an amount per share equal to the fair market value
(determined based on the manner in which the value of the non-cash consideration
was determined in connection with such transaction) of the per share
consideration received by the Carlyle Stockholder(s)), a number of Restricted
Securities (including any options that vest as a result of the consummation of
such Transfer to such Third Party Purchaser(s)) that, in the aggregate, equal
the number derived by multiplying (A) the total number of Restricted Securities
owned by such Service Provider Stockholder (including any options that vest as a
result of the consummation of such Transfer to such Third Party Purchaser(s));
by (B) a fraction, the numerator of which is the total number of shares of
Common Stock to be sold by the Carlyle Stockholder(s) in connection with such
transaction or series of related transactions, and the denominator of which is
the total number of the then-outstanding shares of Common Stock collectively
held by the Carlyle Stockholder(s); provided that the Bring-Along Right may be
exercised by the Carlyle Stockholder(s) prior to the earlier of (i) the second
anniversary of the date hereof and (ii) the date that William C. Stone ceases to
be Chief Executive of the Company, if William C. Stone or any of his Permitted
Transferees are transferring shares of Common Stock in such transaction or
series of related transactions or consent in writing to such exercise of the
Bring-Along Right. For purposes of this Section 2 and Section 3 hereof, the
phrase "number of Restricted Securities" held by any Person or group of Persons
shall mean the number of Restricted Shares held by such Person or group of
Persons plus the number of shares of Common Stock issuable upon exercise of
Vested Options held by such Person or group of Persons.

          (b) If any Carlyle Stockholder(s) elect to exercise the Bring-Along
Right under this Section 2 with respect to the Restricted Securities held by the
Service Provider Stockholders, then the Carlyle Stockholder owning a majority of
the shares of Common Stock to be Transferred shall so notify each Service
Provider Stockholder in writing (a "Bring-Along Notice"). Each Bring-Along
Notice shall set forth: (i) the name of the Third Party Purchaser(s) and the
number of shares of Common Stock proposed to be sold by the Carlyle
Stockholder(s) to such Third Party Purchaser(s); (ii) the proposed amount and
form of consideration and material terms and conditions of payment offered by
the Third Party Purchaser(s) and a summary of any other material terms
pertaining to the Transfer ("Third Party Terms"); and (iii) the number of
Restricted Securities that such Service Provider Stockholder shall be required
to sell in such Transfer (as determined in accordance with Section 2(a) above).
The Bring-Along Notice shall be given at least fifteen (15) days before the
closing of the proposed Transfer.

                                       3

<PAGE>

          (c) Upon the giving of a Bring-Along Notice, such Service Provider
Stockholder shall be obligated to sell such number of Restricted Securities as
is set forth in the Bring-Along Notice on the Third Party Terms.

          (d) At the closing of the Transfer to any Third Party Purchaser(s)
pursuant to this Section 2, the Third Party Purchaser(s) shall remit to such
Service Provider Stockholder (i) the consideration for the total sales price of
the Restricted Securities held by such Service Provider Stockholder sold
pursuant hereto, minus (ii) such Service Provider Stockholder's pro rata portion
of the consideration to be escrowed or otherwise held back, if any, in
accordance with the Third Party Terms, minus (iii) the aggregate exercise price
of any Vested Options being Transferred by such Service Provider Stockholder to
such Third Party Purchaser(s), against delivery by such Service Provider
Stockholder of (i) certificates for such Restricted Shares, duly endorsed for
Transfer or with duly executed stock powers reasonably acceptable to the
Company, and/or (ii) an instrument evidencing the Transfer or the cancellation
of the Vested Options subject to the Bring-Along Right reasonably acceptable to
the Company, and the compliance by such Service Provider Stockholder with any
other conditions to closing generally applicable to the Carlyle Stockholder(s)
and all other holders of Common Stock selling shares in such transaction, which
transaction will not subject any Service Provider Stockholder to any liability
other than (i) such Service Provider Stockholder's pro rata share of any
liability to which the holders of Common Stock selling shares in such
transaction are subject in connection with such liability and (ii) liabilities
in respect of any representation, warranty or indemnity with respect to the
title and ownership of the Restricted Securities being sold by such Service
Provider Stockholder. In the event that the proposed Transfer of the Common
Stock to such Third Party Purchaser is not consummated, the Bring Along Right
shall continue to be applicable to any proposed subsequent Transfer of the
Common Stock by any Carlyle Stockholder(s) pursuant to this Section 2.

          (e) In the event that (i) any Carlyle Stockholder exercises its rights
pursuant to this Section 2, or (ii) a Company Sale is approved by the Board and
the holders of fifty percent (50%) or more of the then-outstanding shares of
Common Stock, each Service Provider Stockholder shall consent to and raise no
objections against such transaction, and if any such transaction is structured
as a sale of stock, each Service Provider Stockholder shall take all actions
that the Board and/or the Carlyle Stockholder(s) reasonably deem necessary or
desirable in connection with the consummation of such transaction. Without
limiting the generality of the foregoing, each Service Provider Stockholder
agrees that it (i) shall consent to and raise no objections against such
transaction; (ii) shall execute any Common Stock purchase agreement, merger
agreement or other agreement entered into with the purchaser with respect to
such transaction setting forth the Third Party Terms and any ancillary agreement
(related to the Transfer of the shares or the Company Sale, but not with respect
to employment) with respect thereto; (iii) shall vote the Common Stock held by
such Service Provider Stockholder in favor of such transaction (including
executing a written consent of stockholders approving such transaction); and
(iv) shall refrain from the exercise of dissenters' appraisal rights with
respect to such transaction. In addition, in connection with any such Company
Sale, each holder of Vested Options agrees that, at the election of the Board,
each outstanding Vested Option shall be terminated and converted into the right
to receive cash consideration in connection with such

                                       4

<PAGE>

Company Sale in an amount equal to (x) the fair market value of the per share
consideration received in connection with such Company Sale by the Carlyle
Stockholder(s) (which value shall, in the case of any non-cash consideration, be
determined based on the manner in which the fair market value of such non-cash
consideration was determined in connection with such Company Sale), less (y) the
exercise price of such Vested Option and any applicable withholding taxes.

          (f) If the Company or the holders of the Company's securities enter
into any negotiation or transaction for which Rule 506 (or any similar rule then
in effect) promulgated under the Securities Act may be available with respect to
such negotiation or transaction (including a merger, consolidation, or other
reorganization), each Service Provider Stockholder shall, if requested by the
Company, appoint a purchaser representative (as such term is defined in Rule 501
of the Securities Act) reasonably acceptable to the Company. If such purchaser
representative was designated by the Company, the Company shall pay the fees of
such purchaser representative, but if any Service Provider Stockholder appoints
another purchaser representative, such Service Provider Stockholder shall be
responsible for the fees of the purchaser representative so appointed.

          (g) Each Service Provider Stockholder shall bear its pro rata share of
the costs of any Company Sale or other transaction (pursuant to this Agreement
or otherwise) in which it sells Restricted Securities to the extent such costs
are incurred for the benefit of all holders of Restricted Securities and are not
otherwise paid by the Company or the acquiring party.

Section 3. Tag-Along Right.

          (a) In the event that any Carlyle Stockholder(s) propose to Transfer
capital stock of the Company to a Third Party Purchaser, then each Service
Provider Stockholder shall have the right (the "Tag-Along Right") to request
that the proposed Third Party Purchaser purchase from such Service Provider
Stockholder up to the number of whole Restricted Securities equal to the number
derived by multiplying (x) the total number of shares of Common Stock that the
proposed Third Party Purchaser has agreed or committed to purchase plus the
total number of shares of Common Stock that are issuable upon conversion,
exercise or exchange of Vested Options or Convertible Securities that the
proposed Third Party Purchaser has agreed or committed to purchase, by (y) a
fraction, the numerator of which is the total number of Restricted Securities
(including any options that vest as a result of the consummation of such
Transfer to such Third Party Purchaser but excluding (i) shares issuable upon
the exercise of unvested options and (ii) any Vested Options that have an
exercise price per share of Common Stock greater than the price per share of
Common Stock to be paid by the Third Party Purchaser) owned by such Service
Provider Stockholder, and the denominator of which is the aggregate number of
shares of Common Stock collectively owned by the Carlyle Stockholders, such
Service Provider Stockholder and all other holders of Common Stock plus the
aggregate number of shares of Common Stock issuable upon conversion, exercise or
exchange of Vested Options and Convertible Securities (excluding (i) shares
issuable upon the exercise of unvested options and (ii) any Vested Options or
other Convertible Securities that have an exercise or conversion price per share
of Common Stock greater than the price per shares of Common Stock to be paid

                                       5

<PAGE>

by the Third Party Purchaser) owned by all Carlyle Stockholder(s), such Service
Provider Stockholder and all other holders of Common Stock, Vested Options, or
other Convertible Securities. Any Restricted Securities purchased from the
Service Provider Stockholders pursuant to this Section 3(a) shall be purchased
at the same price per share of Common Stock (less, in the case of a Vested
Option, the exercise price thereof) and upon the same terms and conditions as
such proposed Transfer by the Carlyle Stockholder(s) (provided, however, that
(i) in the event that the Carlyle Stockholder(s) are granted the right to
appoint any director or directors of any Person in connection with such
Transfer, the Carlyle Stockholder(s) shall be entitled to designate such member
or members of the board of directors of such Person and (ii) in the event that
any portion of the consideration payable to the Carlyle Stockholder(s) in
connection with such Transfer is in a form other than cash, and the Third Party
Purchaser notifies the Carlyle Stockholder(s) that the Third Party Purchaser
desires to provide to the Service Provider Stockholders exercising their rights
under this Section 2 consideration solely in cash in lieu of the non-cash
consideration to be provided to the Carlyle Stockholder(s), then, at the
election of the Carlyle Stockholder(s), the consideration payable to such
Service Provider Stockholders in connection with such Transfer may consist
solely of cash, in an amount per share equal to the fair market value
(determined based on the manner in which the value of the non-cash consideration
was determined in connection with such transaction) of the per share
consideration received by the Carlyle Stockholder(s)).

          (b) The Carlyle Stockholder(s) shall notify each Service Provider
Stockholder in writing in the event such Carlyle Stockholder(s) propose to make
a Transfer or series of Transfers giving rise to the Tag-Along Right at least
fifteen (15) business days prior to the date on which such Carlyle
Stockholder(s) expect to consummate such Transfer (the "Sale Notice") which
notice shall specify the number of shares of Common Stock which the Third Party
Purchaser intends to purchase in such Transfer. The Tag-Along Right may be
exercised by any Service Provider Stockholder by delivery of a written notice to
the Carlyle Stockholder(s) proposing to sell securities of the Company (the
"Tag-Along Notice") within ten (10) business days following receipt of the Sale
Notice from such Carlyle Stockholder(s). The Tag-Along Notice shall state the
number of Restricted Securities that the Service Provider Stockholder proposes
to include in such Transfer to the proposed Third Party Purchaser (not to exceed
the number as determined above). In the event that the proposed Third Party
Purchaser does not purchase the specified number of Restricted Securities from
the Service Provider Stockholders at the same price per share of Common Stock
(less, in the case of a Vested Option, the exercise price thereof) and on the
same terms and conditions as such proposed Transfer by the Carlyle
Stockholder(s) (provided, however, that in the event that the Carlyle
Stockholder(s) are granted the right to appoint any director or directors of any
Person in connection with such Transfer, the Carlyle Stockholder(s) shall be
entitled to designate such member or members of the board of directors of such
Person), then the Carlyle Stockholders shall not be permitted to sell any shares
of Common Stock to the proposed Third Party Purchaser unless such Carlyle
Stockholder(s) purchase from the Service Provider Stockholder such specified
number of Restricted Securities on the same terms and conditions as specified in
such Sale Notice.

          (c) At the closing of the Transfer to any Third Party Purchaser
pursuant to this Section 3, the Third Party Purchaser shall remit to each
Service Provider Stockholder exercising

                                       6

<PAGE>

his rights under this Section 3 (x) the consideration for the total sales price
of the Restricted Securities (calculated in the manner set forth above) held by
such Service Provider Stockholder sold pursuant hereto, minus (y) the aggregate
exercise price of any Vested Options being Transferred by such Service Provider
Stockholder to such Third Party Purchaser(s), minus (z) such Service Provider
Stockholder's pro rata portion of any such consideration to be escrowed or
otherwise held back, if any, in accordance with the Third Party Terms, against
delivery by such Service Provider Stockholder of certificates for such
Restricted Shares subject to the Tag Along Right, duly endorsed for Transfer or
with duly executed stock powers reasonably acceptable to the Company, and/or an
instrument evidencing the Transfer or the cancellation of the Vested Options
being sold reasonably acceptable to the Company, and the compliance by such
Service Provider Stockholder with any other conditions to closing generally
applicable to the Carlyle Stockholder(s) and all other holders of Common Stock,
Vested Options or Convertible Securities selling securities in such transaction.

Section 4. Dividend Equivalents.

          (a) Each Service Provider Stockholder who holds Assumed Options as of
the record date of a cash dividend that is declared by the Company on shares of
Common Stock, will receive, with respect to each Assumed Option held by the
Service Provider Stockholder on such record date, a cash payment (the "Dividend
Equivalent"), less any applicable withholding taxes, on the date of the payment
of such cash dividend (or, if later, payment shall be made at the earliest time
permitted under the terms of the agreements governing any indebtedness to which
the Company or any of its subsidiaries may be a party) equal to the product of:

               (i) the difference between (1) the number of shares of Common
     Stock subject to such Assumed Options, minus (2) a number of shares of
     Common Stock equal to (x) the aggregate exercise price of such Assumed
     Options, divided by (y) the fair market value of a share of Common Stock
     immediately prior to the record date of such dividend (rounded down to the
     nearest whole share of Common Stock); and

               (ii) the dollar amount of such dividend per share of Common
     Stock.

          (b) The fair market value of a share of Common Stock for purposes of
this Section 4 shall be reasonably determined by the Board, taking into account
the most recent Third Party Valuation (defined below) obtained by the Company.

          (c) In no event shall a Service Provider Stockholder be eligible for a
Dividend Equivalent (i) in connection with an extraordinary cash dividend where
the Assumed Options are adjusted to reflect such extraordinary cash dividend, or
(ii) on or after the Service Provider Stockholder's Termination of Service.

          (d) Each Service Provider Stockholder understands and agrees that each
Assumed Option that is an "incentive stock option," as such term is defined in
Section 422 of the Code, shall, as a result of this Section 4 and Section 6, no
longer be an "incentive stock option" and instead will be treated for tax
purposes as a non-qualified stock option.

                                       7

Section 5. Rights to Repurchase Restricted Securities.

          (a) During the period beginning on the date of the Service Provider
Stockholder's Termination of Service and ending on the date nine (9) months
following the later of (i) the date of such Termination of Service and (ii) the
date of the exercise of any Vested Options held by the Service Provider
Stockholder as of the date of such Termination of Service, the Company shall
have the option to repurchase the Restricted Securities (including any Vested
Options) held by the terminated Service Provider Stockholder and/or his or her
Permitted Transferees (collectively, the "Call Right"); provided, however, that
such Call Right shall not apply to any Assumed Options (or underlying shares of
Common Stock) held by any Service Provider Stockholder that is terminated by the
Company or one of its subsidiaries without Cause or that resigns from the
Company or one of its subsidiaries with Good Reason. The Call Right may be
exercised once with respect to any terminated Service Provider Stockholder. The
purchase price payable by the Company upon exercise of the Call Right (the
"Purchase Price") shall be the fair market value of the Restricted Securities
(which shall mean the fair market value of the Restricted Shares if the Call
Right is with respect to Vested Options, less any applicable exercise price and
withholding taxes), subject to the Call Right on the date of the Call Notice.
The Company shall engage an investment bank to determine the fair market value
of the Common Stock (i.e. the value of the Company in its entirety) (a "Third
Party Valuation") at least once every twelve (12) months; provided that the
Company shall not be required to obtain a Third Party Valuation prior to March
31, 2007. The fair market value of the Restricted Securities subject to a Call
Right shall be reasonably determined by the Board, taking into account the most
recent Third Party Valuation obtained by the Company; provided that when
determining fair market value for purposes of this Section 5, the Board shall
not further discount the fair market value of the Restricted Securities solely
because (i) it is determining the fair market value of Restricted Securities
that constitute less than a majority of all of the outstanding shares of Common
Stock of the Company or (ii) there is no liquid public market for the Restricted
Securities; provided further that the foregoing shall not limit the ability of
an investment bank or the Board to take into account the fact that there is no
liquid public market when determining the value of the Common Stock. The Call
Right shall be exercised by written notice (the "Call Notice") to such Service
Provider Stockholder given in accordance with Section 10(f) of this Agreement on
or prior to the last day on which the Call Right may be exercised by the
Company. Notwithstanding the foregoing, to the extent Restricted Securities are
purchased pursuant to a plan or arrangement that is intended to comply with
Section 260.140.41 of Title 10 of the California Code of Regulations, the Call
Right with respect to such Restricted Securities held by employees who are not
managers, directors, consultants or officers of the Company or any of its
subsidiaries shall comply with Section 260.140.41 of Title 10 of the California
Code of Regulations, as determined by the Board.

          (b) The repurchase of Restricted Securities pursuant to the exercise
of the Call Right shall take place on a date specified by the Company, but in no
event later than sixty (60) days following the date of the exercise of such Call
Right or, if later, within ten (10) days following the receipt by the Company of
all necessary governmental approvals. On such date, such Service Provider
Stockholder shall transfer the Restricted Securities subject to the Call Notice
to the Company, free and clear of all liens and encumbrances, by delivering to
the

                                       8

<PAGE>

Company the certificates or other documents representing the Restricted
Securities to be purchased, duly endorsed for transfer to the Company or
accompanied by a stock power duly executed in blank, and the Company shall pay
to such Service Provider Stockholder the Purchase Price in cash or by bank or
cashier's check.

Section 6. Assumed Option Tax Withholding and Net Exercise.

          (a) Each Service Provider Stockholder who holds an Assumed Option,
upon exercise thereof within ninety (90) days of the scheduled expiration of
such Assumed Option, shall have the right to require the Company to retain
shares of Common Stock underlying such Assumed Option having a fair market value
on the date of the exercise of the Assumed Option equal to the amount of the
Service Provider Stockholder's tax withholding obligation that arises in
connection with the exercise of such Assumed Option; provided that the foregoing
is at such time permitted under the terms of the agreements governing any
indebtedness to which the Company or any of its subsidiaries may be a party; and
provided, further that no fractional shares of Common Stock will be retained to
satisfy any portion of the withholding tax and the Service Provider Stockholder
hereby agrees to satisfy any additional amount of withholding taxes that are not
satisfied through the retention of shares of Common Stock by the Company. Any
shares of Common Stock retained by the Company pursuant to this Section 6 shall
be deducted from the underlying shares to be received by such Service Provider
Stockholder upon exercise of the Assumed Option.

          (b) With the consent of the Board and to the extent permitted by law,
each Service Provider Stockholder may pay the exercise price of an Assumed
Option for the shares of Common Stock with respect to which such Assumed Option
is exercised through the surrender of shares of Common Stock then issuable upon
exercise of the Assumed Option having a fair market value on the date of the
exercise of the Assumed Option equal to the aggregate exercise price of the
exercised portion of the Assumed Option (in which case the Service Provider
Stockholder will be deemed the legal owner of such surrendered shares of Common
Stock at the time of the exercise of the Assumed Option); provided that the
foregoing is at such time permitted under the terms of the agreements governing
any indebtedness to which the Company or any of its subsidiaries may be a party;
and provided, further that no fractional shares of Common Stock may be
surrendered to satisfy any portion of the exercise price and the Service
Provider Stockholder hereby agrees to satisfy any additional amount of exercise
price that is not satisfied through the surrender of shares of Common Stock by
the Company.

          (c) The fair market value of a share of Common Stock for purposes of
this Section 4 shall be reasonably determined by the Board, taking into account
the most recent Third Party Valuation obtained by the Company.

Section 7. Permitted Transfers.

          Anything herein to the contrary notwithstanding, the provisions of the
first sentence of Section 1 shall not apply to: (a) any Transfer of Restricted
Shares by a Service Provider Stockholder by gift to, or for the benefit of, any
member or members of his or her immediate family (which shall include any
spouse, lineal ancestor or descendant or sibling) or to

                                       9

<PAGE>

a trust, partnership or limited liability company for the benefit of such
members; provided that such Service Provider Stockholder shall retain sole and
exclusive control over the voting and disposition of said Restricted Shares
until the termination of this Agreement; or (b) any Transfer of Restricted
Shares by a Service Provider Stockholder to the heirs, executors or legatees of
such Service Provider Stockholder by operation of law upon the death or
incapacity of such Service Provider Stockholder (each of the Transfers
referenced in clauses (a) and (b) above being referred to herein as a "Permitted
Transfer"); provided that, in each case, such Transfer is effected in compliance
with all of the provisions of Section 1 hereof other than the restrictions
contained in the first sentence of Section 1 hereof. The recipient of any
Restricted Shares pursuant to the foregoing shall be referred to herein as a
"Permitted Transferee" and shall be deemed a Service Provider Stockholder for
all purposes of this Agreement.

Section 8. Termination.

          This Agreement, and the respective rights and obligations of the
Parties, shall terminate (i) upon the consummation of a Company Sale or (ii)
with respect to any Service Provider Stockholder, upon execution of a written
agreement of such Service Provider Stockholder, the Initial Carlyle Stockholders
and the Company to terminate this Agreement; provided that (i) first sentence of
Section 1 and the provisions of Sections 3, 4, 5 and 6 shall terminate upon the
consummation of an IPO.
