Manager is subject to an Employment Agreement, he/she will abide by the
non-competition and non-solicitation covenants contained therein, which are

3.4(f), as follows:

          (a) During the term of Employment by the Company or any of its
Subsidiaries and for the period of time set forth on Schedule II opposite such
Senior Manager's name following the date such Senior Manager ceases to be
employed by the Company for any reason (the "Restricted Period"), such Senior
Manager will not, whether on his/her own behalf or on behalf of or in
conjunction with any Person, directly or indirectly solicit or assist in
soliciting in competition with the Company or any of its Subsidiaries, the
business of any client or prospective client:

     dealings on behalf of the Company or its Subsidiaries during the one year
     period preceding such Senior Manager's termination of Employment;

               (ii) with whom employees reporting to such Senior Manager have
     had personal contact or dealings on behalf of the Company or any of its
     Subsidiaries during the one year immediately preceding such Senior
     Manager's termination of Employment; or

               (iii) for whom such Senior Manager had direct or indirect
     responsibility during the one year immediately preceding such Senior
     Manager's termination of Employment.

          (b) During the Restricted Period, such Senior Manager will not
directly or indirectly:

               (i) engage in any business that competes with the business of the
     Company or its Subsidiaries (including, without limitation, businesses
     which the Company or its Subsidiaries have specific plans to conduct in the
     future and as to which such Senior Manager is aware of such planning) in
     any geographic area in which the Company or its Subsidiaries conducts such
     business (a "Competitive Business");

               (ii) enter the employ of, or render any services to, any Person
     (or any division or controlled or controlling Affiliate of any Person) who
     or which engages in a Competitive Business;

               (iii) acquire a financial interest in, or otherwise become
     actively involved with, any Competitive Business, directly or indirectly,
     as an individual, partner, shareholder, officer, director, principal,
     agent, trustee or consultant; or

               (iv) interfere with, or attempt to interfere with, business
     relationships (whether formed before, on or after the date of this
     Agreement) between the Company or any of its Subsidiaries, on the one hand,
     and customers, clients, suppliers partners, members or investors of the
     Company or its Subsidiaries, on the other hand.

                                      -5-

          (c) During the Restricted Period, such Senior Manager will not,
whether on such Senior Manager's own behalf or on behalf of or in conjunction
with any Person, directly or indirectly:

               (i) solicit or encourage any employee of the Company or its
     Subsidiaries to leave the Employment of the Company or its Subsidiaries
     (except in cases during a Senior Manager's Employment where such Senior
     Manager reasonably believes such action to be in the best interests of the
     Company or its Subsidiaries); or

               (ii) hire any such employee who was employed by the Company or
     its Subsidiaries as of the date of such Senior Manager's termination of
     Employment with the Company or who left the Employment of the Company or
     its Subsidiaries coincident with, or within one year prior to, the
     termination of such Senior Manager's Employment with the Company (other
     than any such employee whose Employment with the Company is terminated by
     the Company without Cause).

          (d) During the Restricted Period, such Senior Manager will not,
directly or indirectly, encourage or solicit to cease to work with the Company
or its Subsidiaries any consultant then under contract with the Company or its
Subsidiaries.

Senior Manager may, directly or indirectly own, solely as an investment,
securities of any Person engaged in the business of the Company or its
Subsidiaries which are publicly traded on a national or regional stock exchange
or on the over-the-counter market if the Senior Manager (i) is not a controlling
person of, or a member of a group which controls, such person and (ii) does not,
directly or indirectly, own 5% or more of any class of securities of such
Person.

          (f) It is expressly understood and agreed that although the Senior
Managers and the Company consider the restrictions contained in this Section 3.4
to be reasonable, if a final judicial determination is made by a court of
competent jurisdiction that the time or territory or any other restriction
contained in this Agreement is an unenforceable restriction against the relevant
Senior Manager, the provisions of this Agreement will not be rendered void but
will be deemed amended to apply as to such maximum time and territory and to
such maximum extent as such court may judicially determine or indicate to be
enforceable. Alternatively, if any court of competent jurisdiction finds that
any restriction contained in this Agreement is unenforceable, and such
restriction cannot be amended so as to make it enforceable, such finding will
not affect the enforceability of any of the other restrictions contained herein.

     Section 3.5. Confidential Information. (a) No Management Stockholder will
at any time (whether during or after such Management Stockholder's employment
with the Company) (i) retain or use for the benefit, purposes or account of such
Management Stockholder or any other Person; or (ii) disclose, divulge, reveal,
communicate, share, transfer or provide access to any Person outside the Company
(other than its professional advisers who are bound by confidentiality
obligations), any non-public, proprietary or

Company on a confidential basis ("Confidential Information") without the prior

          (b) "Confidential Information" will not include any information that
is (i) generally known to the industry or the public other than as a result of
such Management Stockholder's breach of this covenant or any breach of other
confidentiality obligations by third parties; (ii) made legitimately available
to the Management Stockholder by a third party without breach of any
confidentiality obligation; or (iii) required by law or a court of competent
jurisdiction to be disclosed; provided that such Management Stockholder will
give prompt written notice to the Company of such requirement, disclose no more
information than is so required, and cooperate with any attempts by the Company
to obtain a protective order or similar treatment.

          (c) [Intentionally Omitted]

any reason, the Management Stockholder will (i) cease and not thereafter

                                   ARTICLE II
                               REGISTRATION RIGHTS

     Section 2.1. Piggy-Back Registration. If at any time following the
consummation of an Initial Public Offering the Company proposes to file a
registration statement under the Securities Act with respect to an offering by
the Company for its own account and/or for the account of any of its security
holders of any common stock (other than (i) a registration statement on Form S-4
(or F-4) or S-8 (or any substitute form that may be adopted by the Commission)
or (ii) a registration statement filed in connection with an exchange offer or
an offering of securities solely to the Company's existing securityholders),
then the Company shall give written notice of such proposed filing to the
Holders as soon as practicable (but in no event less than 15 days before the
anticipated filing date), and such notice shall identify the anticipated filing
date and offer such Holders the opportunity to register such number of shares of
Registrable Securities as each such Holder may request (which request shall
specify the Registrable Securities intended to be disposed of by such Holder and
the intended method of distribution thereof and shall be delivered to the
Company at least two days prior to the anticipated filing date) (a "Piggy-Back
Registration"). The Company shall use its commercially reasonable efforts to
cause the managing Underwriter or Underwriters of a proposed underwritten
offering to permit the Registrable Securities requested to be included in a
Piggy-Back Registration to be included on the same terms and conditions to
permit the sale or other disposition of such Registrable Securities in
accordance with the intended method of distribution thereof. Any Holder shall
have the right to withdraw its request for inclusion of its Registrable
Securities in any registration statement pursuant to this Section 2.1 by giving
written notice to the Company of its request to withdraw. The Company may
withdraw a Piggy-Back Registration at any time prior to the time it becomes
effective, provided that, in such event, the Company shall reimburse Holders
requested to be included in such Piggy-Back Registration for all Registration
Expenses (including reasonable counsel fees and expenses) incurred prior to such
withdrawal; provided, further, a Holder shall not be eligible for piggy-back
registration rights pursuant to this Section 2.1 with respect to any
registration statements which are initially filed by the Company after the
Piggy-Back Termination Date with respect to such Holder (or offerings made after
such Piggy-Back Termination Date pursuant to shelf registration statements
previously on file). For these purposes, the "Piggy-Back Termination Date" shall
mean the second anniversary of the Company's Initial Public Offering; provided,
however, with respect to any Holder whose status as an employee or director of
the Company or its subsidiaries terminates prior to such second anniversary, the
Holder may, by written notice to the Company, elect to have the Piggy-Back
Termination Date (with respect to such Holder and his Permitted Transferees
only) occur any date after the date of such termination of employee or director
status and before such second anniversary.

                                      -2-

     Section 2.2. Reduction of Offering. Notwithstanding anything contained
herein, if the managing Underwriter(s) of an offering described in Section 2.1
determine that the offering that the Holders, the Company and/or such other
Persons intend to make is such that the success of the offering would be
materially and adversely affected by inclusion of the Registrable Securities
requested to be included, then the Company shall include in such registration:
(i) first, the shares, if any, proposed to be registered by the Company for its
own account or for the account of a holder exercising "demand registration
rights"; and (ii) second, an amount of securities requested to be included in
such registration (including pursuant to Section 2.1) by the holders exercising
"piggy-back registration rights" (such amount to be allocated among such holders
in proportion to the number of shares of Common Stock held by such holders).
Holders may not sell shares in a Public Offering if the managing Underwriter(s)
determine in their reasonable business judgment that such participation will
have an adverse impact on such Public Offering. Notwithstanding any provision in
this Agreement to the contrary, no Holder may exercise piggyback registration
rights to the extent it would otherwise result in the sale by him or her, on a
cumulative basis taking into account all prior sales, of a greater percentage of
the Common Stock that has ever been held by him than the percentage equal to the
cumulative shares of Common Stock sold by Cypress divided by the total shares of
Common Stock ever held by Cypress. The Holders agree that they will not sell any
shares in an Initial Public Offering.

                                  ARTICLE III
                             REGISTRATION PROCEDURES

     Section 3.1. Filings; Information. Whenever the Holders have requested that
any Registrable Securities be registered pursuant to this agreement, the Company
will use its reasonable efforts to effect the registration of such Registrable
Securities in accordance with the intended method of disposition thereof as
quickly as practicable, and in connection with any such request:

          (a) The Company will as expeditiously as practicable prepare and file
with the Commission a registration statement on any form for which the Company
then qualifies or which counsel for the Company shall deem appropriate and which
form shall be available for the sale of the Registrable Securities to be
registered thereunder in accordance with the intended method of distribution
thereof (it being understood that the Company shall use Form S-3 (or any
replacement form) if such form is then available), and use its commercially
reasonable efforts to cause such filed registration statement to become
effective.

          (b) The Company will prepare and file with the Commission 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 and to comply with the provisions of the Securities Act with
respect to the disposition of all securities covered by such registration
statement until such time as all of such securities have been disposed of in
accordance with the intended methods of disposition by the Selling Holder or
Selling Holders thereof set forth in such registration statement.

          (c) The Company will, prior to filing a registration statement or
prospectus or any amendment or supplement thereto, furnish to each Selling
Holder, counsel

                                      -3-

representing any Selling Holders, and each Underwriter, if any, of the
Registrable Securities covered by such registration statement copies of such
registration statement as proposed to be filed, together with exhibits thereto,
which documents will be subject to review by the foregoing within 5 Business
Days after delivery, and thereafter furnish to such Selling Holder, counsel and
Underwriter, if any, such number of copies of such registration statement, each
amendment and supplement thereto (in each case including all exhibits thereto
and documents incorporated by reference therein), the prospectus included in
such registration statement (including each preliminary prospectus) and such
other documents as such Selling Holder or Underwriter may reasonably request in
order to facilitate the disposition of the Registrable Securities owned by such
Selling Holder.

          (d) After the filing of the registration statement, the Company will
promptly notify each Selling Holder covered by such registration statement of
any stop order issued or threatened by the Commission and take all reasonable
actions required to prevent the entry of such stop order or to remove it if
entered.

          (e) The Company will use its commercially reasonable efforts to (i)
register or qualify the Registrable Securities under such other securities or
blue sky laws of such jurisdictions in the United States and such other
jurisdictions as any Selling Holder reasonably (in light of such Selling
Holder's intended plan of distribution) requests and (ii) cause such Registrable
Securities to be registered with or approved by such other governmental agencies
or authorities in the United States as may be necessary by virtue of the
business and operations of the Company and do any and all other acts and things
that may be reasonably necessary or advisable to enable such Selling Holder to
consummate the disposition of the Registrable Securities owned by such Selling
Holder; provided that the Company will not be required to (A) qualify generally
to do business in any jurisdiction where it would not otherwise be required to
qualify but for this paragraph (d), (B) subject itself to taxation in any such
jurisdiction or (C) consent to general service of process in any such
jurisdiction.

          (f) The Company will immediately notify each Selling Holder of such
Registrable Securities, at any time when a prospectus relating thereto is
required to be delivered under the Securities Act, of the occurrence of an event
requiring the preparation of a supplement or amendment to such prospectus so
that, as thereafter delivered to the purchasers of such Registrable Securities,
such prospectus will not contain an untrue statement of a material fact or omit
to state any material fact required to be stated therein or necessary to make
the statements therein not misleading, and will promptly make available to each
Selling Holder any such supplement or amendment.

          (g) The Company will enter into customary agreements (including, if
applicable, an underwriting agreement in customary form) and take such other
actions as are reasonably required in order to expedite or facilitate the
disposition of such Registrable Securities in accordance with the intended plan
of distribution of the Selling Holders.

          (h) The Company will deliver promptly to each Selling Holder of such
Registrable Securities and each Underwriter, if any, subject to restrictions
imposed by the United States federal government or any agency or instrumentality
thereof, copies of all correspondence between the Commission and the Company and
its counsel or auditors and

                                      -4-

all memoranda relating to discussions with the Commission or its staff with
respect to the registration statement and make available for inspection by any
Selling Holder of such Registrable Securities, any Underwriter participating in
any disposition pursuant to such registration statement and any attorney,
accountant or other professional retained by any such Selling Holder or
Underwriter (collectively, the "Inspectors"), all financial and other records,
pertinent corporate documents and properties of the Company (collectively, the
"Records"), as shall be reasonably necessary to enable them to perform a
reasonable and customary due diligence investigation, and cause the Company's
officers, directors and employees to supply all information reasonably requested
by any Inspectors in connection with such registration statement. Records which
the Company determines, in good faith, to be confidential and which it notifies
the Inspectors are confidential shall not be disclosed by the Inspectors unless
(i) the disclosure of such Records is necessary to avoid or correct a
misstatement or omission in such registration statement or (ii) the disclosure
or release of such Records is requested or required pursuant to oral questions,
interrogatories, requests for information or documents or a subpoena or other
order from a court of competent jurisdiction or other process; provided that
prior to any disclosure or release pursuant to clause (ii), the Inspectors shall
provide the Company with prompt notice of any such request or requirement so
that the Company may seek an appropriate protective order or waive such
Inspectors' obligation not to disclose such Records; and provided, further, that
if failing the entry of a protective order or the waiver by the Company
permitting the disclosure or release of such Records, the Inspectors, upon
advice of counsel, are compelled to disclose such Records, the Inspectors may
disclose that portion of the Records which counsel has advised the Inspectors
that the Inspectors are compelled to disclose. Each Selling Holder of such
Registrable Securities agrees that it will, upon learning that disclosure of
such Records is sought in a court of competent jurisdiction, give notice to the
Company and allow the Company at its expense, to undertake appropriate action to
prevent disclosure of the Records deemed confidential.

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

          (j) The Company will use its commercially reasonable efforts to comply
with all applicable rules and regulations of the Commission, and make available
to its securityholders, as soon as reasonably practicable, an earnings statement
covering a period of 12 months, beginning within three months after the
effective date of the registration statement, which earnings statement shall
satisfy the provisions of Section 11(a) of the Securities Act and Rule 158
thereunder.

          (k) The Company will use its commercially reasonable efforts (a) to
cause all such Registrable Securities to be listed on a national securities
exchange (if such shares are not already so listed) and on each additional
national securities exchange on which similar securities issued by the Company
are then listed (if any), if the listing of such Registrable Securities is then
permitted under the rules of such exchange or (b) to secure designation of all
such Registrable Securities covered by such registration statement as a

                                      -5-

NASDAQ "national market system security" within the meaning of Rule 11Aa2-1 of
the Commission or, failing that, to secure NASDAQ authorization for such
Registrable Securities and, without limiting the generality of the foregoing, to
arrange for at least two market makers to register as such with respect to such
Registrable Securities with the NASD.

          (l) The Company will appoint a transfer agent and registrar for all
such Registrable Securities covered by such registration statement not later
than the effective date of such registration statement.

          The Company may require each Selling Holder of Registrable Securities
to promptly furnish in writing to the Company such information regarding the
distribution of the Registrable Securities as the Company may from time to time
reasonably request and such other information as may be legally required in
connection with such registration.

          Each Selling Holder agrees that, upon receipt of any notice from the
Company of the happening of any event of the kind described in Section 3.1(f)
hereof, such Selling Holder will forthwith discontinue disposition of
Registrable Securities pursuant to the registration statement covering such
Registrable Securities until such Selling Holder's receipt of the copies of the
supplemented or amended prospectus contemplated by Section 3.1(f) hereof, and,
if so directed by the Company such Selling Holder will deliver to the Company
all copies, other than permanent file copies then in such Selling Holder's
possession, of the most recent prospectus covering such Registrable Securities
at the time of receipt of such notice. In the event the Company shall give such
notice, the Company shall extend the period during which such registration
statement shall be maintained effective (including the period referred to in
Section 3.1(b) hereof) by the number of days during the period from and
including the date of the giving of notice pursuant to Section 3.1(f) hereof to
the date when the Company shall make available to the Selling Holders of
Registrable Securities covered by such registration statement a prospectus
supplemented or amended to conform with the requirements of Section 3.1(f)
hereof.

     Section 3.2. Registration Expenses. In connection with any registration
statement filed pursuant to Section 2.1, the Company shall pay the following
registration expenses incurred in connection with the registration hereunder
(the "Registration Expenses"): (i) all registration and filing fees, (ii) fees
and expenses of compliance with securities or blue sky laws (including
reasonable fees and disbursements of counsel in connection with blue sky
qualifications of the Registrable Securities), (iii) printing expenses, (iv) the
Company's internal expenses (including, without limitation, all salaries and
expenses of its officers and employees performing legal or accounting duties),
(v) fees and expenses incurred in connection with the listing of the Registrable
Securities, (vi) reasonable fees and disbursements of counsel for the Company
and not more than one counsel for the Selling Holders, as may be chosen by a
majority of the Selling Holders, and customary fees and expenses for independent
certified public accountants retained by the Company (including the expenses of
any comfort letters or costs associated with the delivery by independent
certified public accountants of a comfort letter or comfort letters requested
pursuant to Section 3.1(i) hereof) and (vii) reasonable fees and expenses of any
special experts retained by the Company in connection with such registration.
The Company shall have no

                                      -6-

obligation to pay any underwriting fees, discounts or commissions attributable
to the sale of Registrable Securities.

                                   ARTICLE IV
                        INDEMNIFICATION AND CONTRIBUTION

     Section 4.1. Indemnification by the Company. To the fullest extent
permitted by law, the Company agrees to indemnify and hold harmless each Selling
Holder of Registrable Securities, its officers, directors, employees and agents,
and each person, if any, who controls such Selling Holder within the meaning of
the Securities Act from and against any loss, claim, damage or liability, joint
or several, or any action in respect thereof (including, but not limited to, any
loss, claim, damage, liability or action relating to purchases and sales of
Common Stock) to which such Selling Holder, officer, director, employee or agent
or controlling Person may become subject under the Securities Act or otherwise,
insofar as such loss, claim, damage, liability or action arises out of, or is
based upon, (i) any untrue statement or alleged untrue statement of a material
fact contained in any registration statement, preliminary prospectus or final
prospectus or any amendment or supplement thereto relating to the Registrable
Securities or (ii) any omission or alleged omission to state therein a material
fact required to be stated therein or necessary to make the statements therein
not misleading and shall reimburse each Selling Holder and each such officer,
director, employee, agent and controlling Person for any legal and other
expenses reasonably incurred by that Selling Holder, officer, director,
employee, agent or controlling Person in connection with investigating or
defending or preparing to defend against any such loss, claim, damage, liability
or action as such expenses are incurred, except insofar as the same are
contained in any information furnished in writing to the Company by such Selling
Holder expressly for use therein; provided, however, that the Company shall not
be liable to any Selling Holder or such Person's directors, officers, agents or
controlling Persons, in any such case for any such loss, claim, damage or
liability to the extent that it arises out of or is based upon an untrue
statement or alleged untrue statement or omission or alleged omission made in
connection with such registration statement, preliminary prospectus, final
prospectus or amendments or supplements thereto, in conformity with written
information relating to such Selling Holder furnished to the Company by such
Selling Holder expressly for inclusion therein in connection with such
registration; and, provided, further, that as to any preliminary prospectus or
any final prospectus, this indemnity agreement shall not inure to the benefit of
any Selling Holder or such Person's directors, officers, agents or controlling
Persons, on account of any loss, claim, damage or liability arising from the
sale of Registrable Securities to any Person by such Selling Holder if such
Selling Holder or its representatives failed to send or give a copy of the final
prospectus or a prospectus supplement, as the case may be (excluding documents
incorporated by reference therein), as the same may be amended or supplemented,
to that Person within the time required by the Securities Act, and the untrue
statement or alleged untrue statement of a material fact or omission or alleged
omission to state a material fact in such preliminary prospectus or final
prospectus was corrected in the final prospectus or such prospectus supplement,
as the case may be (excluding documents incorporated by reference therein),
unless such failure resulted from the non-compliance by the Company with Section
3.1(f). The Company also agrees to indemnify any Underwriters of the Registrable
Securities, their officers and directors and each Person who controls such
Underwriters on substantially the same basis as

                                      -7-

that of the indemnification of the Selling Holders provided in this Section 4.1.
The indemnities provided by this Section 4.1 shall remain in full force and
effect regardless of any investigation made by or on behalf of such Selling
Holder or Underwriter.

     Section 4.2. Indemnification by Holders of Registrable Securities. To the
fullest extent permitted by law, each Selling Holder agrees, severally but not
jointly, to indemnify and hold harmless the Company its officers, directors and
agents and each Person, if any, who controls the Company within the meaning of
the Securities Act to the same extent as the indemnity from the Company to such
Selling Holder pursuant to clauses (i) and (ii) of Section 4.1, but only with
reference to information related to such Selling Holder furnished in writing by
such Selling Holder or on such Selling Holder's behalf expressly for use in any
registration statement or prospectus relating to the Registrable Securities, or
any amendment or supplement thereto, or any preliminary prospectus; provided
that the obligation to indemnify will be individual to each Selling Holder and
will be limited to the net amount of proceeds received by such Selling Holder
from the sale of Registrable Securities pursuant to such Registration Statement.
Each Selling Holder also agrees to indemnify and hold harmless Underwriters of
the Registrable Securities, their officers and directors and each Person who
controls such Underwriters on substantially the same basis as that of the
indemnification of the Company provided in this Section 4.2, subject to the
proviso in the first sentence of this Section 4.2. Notwithstanding the
foregoing, the indemnity set forth in this Section 4.2, shall not apply to
amounts paid in settlements effected without the consent of such Selling Holder
(which consent shall not be unreasonably withheld or delayed).

     Section 4.3. Conduct of Indemnification Proceedings. Promptly after receipt
by any person in respect of which indemnity may be sought pursuant to Section
4.1 or 4.2 (an "Indemnified Party") of notice of any claim or the commencement
of any action, the Indemnified Party shall, if a claim in respect thereof is to
be made against the person against whom such indemnity may be sought (an
"Indemnifying Party") notify the Indemnifying Party in writing of the claim or
the commencement of such action, provided that the failure to notify the
Indemnifying Party shall not relieve it from any liability which it may have to
an Indemnified Party otherwise than under Section 4.1 or 4.2, except to the
extent of any actual prejudice resulting therefrom. If any such claim or action
shall be brought against an Indemnified Party, and it shall notify the
Indemnifying Party thereof, the Indemnifying Party shall be entitled to
participate therein, and, to the extent that it wishes, jointly with any other
similarly notified Indemnifying Party, to assume the defense thereof with
counsel satisfactory to the Indemnified Party. After notice from the
Indemnifying Party to the Indemnified Party of its election to assume the
defense of such claim or action, the Indemnifying Party shall not be liable to
the Indemnified Party for any legal or other expenses subsequently incurred by
the Indemnified Party in connection with the defense thereof other than
reasonable costs of investigation; provided that the Indemnified Party shall
have the right to employ separate counsel to represent the Indemnified Party and
its controlling Persons who may be subject to liability arising out of any claim
in respect of which indemnity may be sought by the Indemnified Party against the
Indemnifying Party, but the fees and expenses of such counsel shall be for the
account of such Indemnified Party unless (i) the Indemnifying Party and the
Indemnified Party shall have mutually agreed to the retention of such counsel or
(ii) in the reasonable judgment of such Indemnified Party representation of both
parties by the same counsel would be inappropriate due to actual or

                                      -8-

potential differing interests between them. No Indemnifying Party shall, without
the prior written consent of the Indemnified Party, effect any settlement of any
claim or pending or threatened proceeding in respect of which the Indemnified
Party is or could have been a party and indemnity could have been sought
hereunder by such Indemnified Party, unless such settlement includes an
unconditional release of such Indemnified Party from all liability arising out
of such claim or proceeding.

     Section 4.4. Contribution. If the indemnification provided for in this
Article IV is unavailable to the Indemnified Parties in respect of any losses,
claims, damages, liabilities or expenses referred to herein, then each such
Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall
contribute to the amount paid or payable by such Indemnified Party as a result
of such losses, claims, damages, liabilities or expenses (i) as between the
Company and the Selling Holders on the one hand and the Underwriters on the
other, in such proportion as is appropriate to reflect the relative benefits
received by the Company and the Selling Holders on the one hand and the
Underwriters on the other from the offering of the Registrable Securities, or if
such allocation is not permitted by applicable law, in such proportion as is
appropriate to reflect not only the relative benefits but also the relative
fault of the Company and the Selling Holders on the one hand and of the
Underwriters on the other in connection with the statements or omissions which
resulted in such losses, claims, damages or liabilities, as well as any other
relevant equitable considerations and (ii) as between the Company on the one
hand and each Selling Holder on the other, in such proportion as is appropriate
to reflect the relative fault of the Company and of each Selling Holder in
connection with such statements or omissions, as well as any other relevant
equitable considerations. The relative benefits received by the Company and the
Selling Holders on the one hand and the Underwriters on the other shall be
deemed to be in the same proportion as the total proceeds from the offering (net
of underwriting discounts and commissions but before deducting expenses)
received by the Company and the Selling Holders bear to the total underwriting
discounts and commissions received by the Underwriters, in each case as set
forth in the table on the cover page of the prospectus. The relative fault of
the Company and the Selling Holders on the one hand and of the Underwriters on
the other shall be determined by reference to, among other things, whether the
untrue or alleged untrue statement of a material fact or the omission or alleged
omission to state a material fact relates to information supplied by the Company
and the Selling Holders or by the Underwriters. The relative fault of the
Company on the one hand and of each Selling Holder on the other shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to state
a material fact relates to information supplied by such party, and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such statement or omission.

     The Company and the Selling Holders agree that it would not be just and
equitable if contribution pursuant to this Section 4.4 were determined by pro
rata allocation (even if the Underwriters were treated as one entity for such
purpose) or by any other method of allocation which does not take account of the
equitable considerations referred to in the immediately preceding paragraph. The
amount paid or payable by an Indemnified Party as a result of the losses,
claims, damages or liabilities referred to in the immediately preceding
paragraph shall be deemed to include, subject to the limitations set forth
above, any legal or

                                      -9-

other expenses reasonably incurred by such Indemnified Party in connection with
investigating or defending any such action or claim. Notwithstanding the
provisions of this Section 4.4, no Underwriter shall be required to contribute
any amount in excess of the amount by which the total price at which the
Registrable Securities underwritten by it and distributed to the public were
offered to the public exceeds the amount of any damages which such Underwriter
has otherwise been required to pay by reason of such untrue or alleged untrue
statement or omission or alleged omission, and no Selling Holder shall be
required to contribute any amount in excess of the amount by which the total
price at which the Registrable Securities of such Selling Holder were offered to
the public (less underwriting discounts and commissions) exceeds the amount of
any damages which such Selling Holder has otherwise been required to pay by
reason of such untrue or alleged untrue statement or omission or alleged
omission. No person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the Securities Act) shall be entitled to contribution from
any person who was not guilty of such fraudulent misrepresentation. Each Selling
Holder's obligations to contribute pursuant to this Section 4.4 are several in
proportion to the proceeds of the offering received by such Selling Holder and
not joint.

                                    ARTICLE V
                                  MISCELLANEOUS

     Section 5.1. Participation in Underwritten Registrations. No Person may
participate in any underwritten registration hereunder unless such Person (a)
agrees to sell such Person's securities on the basis provided in any
underwriting arrangements approved by the Persons entitled hereunder to approve
such arrangements and (b) completes and executes all questionnaires, powers of
attorney, indemnities, underwriting agreements and other documents reasonably
required under the terms of such underwriting arrangements and these
Registration Rights.

     Section 5.2. Rule 144. The Company covenants that it will file any reports
required to be filed by it under the Securities Act and the Exchange Act and
that it will take such further action as any Holder may reasonably request, all
to the extent required from time to time to enable Holders to sell Registrable
Securities without registration under the Securities Act within the limitation
of the exemptions provided by (a) Rule 144 under the Securities Act, as such
Rules may be amended from time to time, or (b) any similar rule or regulation
hereafter adopted by the Commission. Upon the request of any Holder, the Company
will deliver to such Holder a written statement as to whether it has complied
with such requirements.

     Section 5.3. Holdback Agreements. If any registration statement shall be in
connection with a Public Offering to be underwritten on a firm commitment basis,
then each Holder of Registrable Securities agrees not to effect any sale or
distribution of the securities being registered or of a similar security of the
Company or any securities convertible into or exchangeable or exercisable for
such securities, including a sale pursuant to Rule 144 under the Securities Act,
during the 14 days prior to, and during the 90-day period beginning on, the
effective date of such Public Offering (except as part of such underwritten
registration), unless the investment banks or underwriters managing the public
offering otherwise agree. Notwithstanding anything to the contrary contained in
the Management Stockholders Agreement or in this Exhibit C, this Section 5.3
shall not apply with respect to any

                                      -10-

registration statements initially filed after the Piggy-Back Termination Date
with respect to a Holder (or offerings made after such Piggy-Back Termination
Date pursuant to shelf registration statements previously on file).

     Section 5.4. Other Registration Rights. Notwithstanding anything contained
in this Exhibit C or the Management Stockholders Agreement to the contrary, no
provision herein or therein shall be interpreted to limit (i) the right of the
Company to grant Cypress or any other Person any right of registration in
respect of any securities of the Company (provided, however, that the Company
shall not enter into any agreement with respect to the Registrable Securities
which would prevent the Company from complying with its obligations under this
Agreement or (ii) the number of times the Company may grant any such right of
registration under the Securities Act to any Person (including Cypress).

                                   ARTICLE II
                               REGISTRATION RIGHTS

          Section 2.1. Demand Registration.

               (a) Request for Registration. At any time on or after the date
180 days following the consummation of an Initial Public Offering or such
earlier date as permitted by the managing underwriters for the Initial Public
Offering, any Holder may request registration under the Securities Act of all or
part of its or their Registrable Securities (a "Demand Registration"); provided
that such request specifies the number of shares of Registrable Securities
proposed to be sold and the intended method of disposition thereof. Holders
shall be entitled to request no more than six (6) Demand Registrations in the
aggregate.

               (b) Selection of Underwriters. If the Holder making the Demand
Registration so elects, the offering of such Registrable Securities pursuant to
such Demand Registration shall be in the form of an underwritten offering. Such
Holder shall select, subject to the Company's reasonable approval, one or more
nationally recognized firms of investment bankers to act as the book-running
managing Underwriter or Underwriters in connection with such offering and shall
select, subject to the Company's reasonable approval, any additional investment
bankers and managers to be used in connection with the offering.

               (c) Effective Registration Statement. A registration effected
pursuant to this Section 2.1 will not be deemed to have been effected unless it
has become effective and has remained continuously effective for a period of 90
days (or, with respect to a registration that is effected pursuant to Form S-3
(or any successor or similar short-form registration), 9 months) or such shorter
period which will terminate when all of the Registrable Securities requested to
be registered thereunder have been sold.

               (d) Registration Statement Form. The Company shall select the
registration statement form for any registration pursuant to this Section 2.1;
provided, that if any registration requested pursuant to this Section 2.1 is
proposed to be effected on Form S-3 (or any successor or similar short-form
registration) and is in connection with an underwritten offering, and if the
managing Underwriter shall advise the Company in writing that, in its opinion,
it is of material importance to the success of such proposed offering to include
in such registration statement information not required to be included pursuant
to such form, then the Company will supplement such registration statement as
reasonably requested by such managing Underwriter.

               (e) Withdrawal. Each demanding Holder may, no less than five
Business Days before any registration statement becomes effective pursuant to
this Section 2.1, withdraw some or all of its Registrable Securities from
inclusion in such registration statement. If all of the Registrable Securities
are withdrawn from inclusion in a registration statement, then the Company may
withdraw such registration statement. If the Company withdraws a registration
statement pursuant to the preceding sentence, then the requested registration
shall be deemed to have been a Demand Registration for purposes of the
limitations on the number of Demand Registrations contained in Section 2.1
unless (i) at the time of the Holders' withdrawal of Registrable Securities,
there has been a material adverse change in the operating results, financial
condition, or business of the Company that was not publicly known at the time
that the

                                       -6-

demand for registration was made, or (ii) the Company has postponed its
obligations under this Agreement as described in paragraph (f).

               (f) Restrictions on Demand Registrations. The Company will not be
obligated to effect any Demand Registration within three months after the
effective date of a Public Offering by the Company pursuant to Section 2.1 or a
Public Offering for which Piggy-Back Registration was fully available. If at the
time of the request to register Registrable Securities pursuant to Section
2.1(a), the Company is engaged, or has fixed plans (which have been or are
reasonably expected to be approved by the Board of Directors within 30 days) to
engage within 90 days of the time of the request, in a registered public
offering as to which the Holders may include such Registrable Securities
pursuant to Section 2.2 hereof, or is engaged in any activity which, in the good
faith determination of the Board of Directors, would be adversely affected by
the requested registration to the material detriment of the Company, then the
Company may at its option direct that such request be delayed for a period not
in excess of 120 days from the effective date of such offering, or in the case
of such other material activity, the date of such request for registration, such
right to delay a request to be exercised by the Company, not more than once
within any twelve-month period. A request for Demand Registration may be
withdrawn if the Company delays the requested Demand Registration pursuant to
this paragraph (f).

          Section 2.2. Piggy-Back Registration. If at any time following the
consummation of an Initial Public Offering, the Company proposes to file a
registration statement under the Securities Act with respect to an offering by
the Company for its own account and/or for the account of any of its security
holders (including in connection with a Demand Registration) of any Common Stock
(other than (i) a registration statement on Form S-4 (or F-4) or S-8 (or any
substitute form that may be adopted by the Commission) or (ii) a registration
statement filed in connection with an exchange offer or an offering of
securities solely to the Company's existing securityholders), then the Company
shall give written notice of such proposed filing to the Holders as soon as
practicable (but in no event less than 15 days before the anticipated filing
date), and such notice shall identify the anticipated filing date and offer such
Holders the opportunity to register such number of shares of Registrable
Securities as each such Holder may request (which request shall specify the
Registrable Securities intended to be disposed of by such Holder and the
intended method of distribution thereof and shall be delivered to the Company at
least two days prior to the anticipated filing date) (a "Piggy-Back
Registration"). The Company shall use its commercially reasonable efforts to
cause the managing Underwriter or Underwriters of a proposed underwritten
offering to permit the Registrable Securities requested to be included in a
Piggy-Back Registration to be included on the same terms and conditions to
permit the sale or other disposition of such Registrable Securities in
accordance with the intended method of distribution thereof. Any Holder shall
have the right to withdraw its request for inclusion of its Registrable
Securities in any registration statement pursuant to this Section 2.2 by giving
written notice to the Company of its request to withdraw. The Company may
withdraw a Piggy-Back Registration at any time prior to the time it becomes
effective, provided that, in such event, the Company shall reimburse Holders
requested to be included in such Piggy-Back Registration for all Registration
Expenses (including reasonable counsel fees and expenses) incurred prior to such
withdrawal.

                                       -7-

               Section 2.3. Reduction of Offering. Notwithstanding anything
contained herein, if the managing Underwriter(s) of an offering described in
Section 2.1 or 2.2 determine that the offering that the Holders, the Company
and/or such other Persons intend to make is such that the success of the
offering would be materially and adversely affected by inclusion of the
Registrable Securities requested to be included, then the Company shall include
in such registration: (a) in the case of a demand registration, (i) first, an
amount of securities requested to be included in such registration by any holder
exercising "demand registration rights" (such amount to be allocated among such
holders in proportion to the number of securities held by such holders) and (ii)
second, the Registrable Securities and any other securities of the Company
requested to be included in such registration (such amount to be allocated among
such holders in proportion to the number of shares of Common Stock held by such
holders); and (b) in the case of a piggy-back registration, (i) first, the
shares, if any, proposed to be registered by the Company for its own account or
for the account of a holder exercising "demand registration rights"; and (ii)
second, an amount of securities requested to be included in such registration
(including pursuant to Section 2.2) by the holders exercising "piggy-back
registration rights" (such amount to be allocated among such holders in
proportion to the number of shares of Common Stock held by such holders).

                                   ARTICLE III
                             REGISTRATION PROCEDURES

               Section 3.1. Filings; Information. Whenever the Holders have
requested that any Registrable Securities be registered pursuant to this
agreement, the Company will use its reasonable efforts to effect the
registration of such Registrable Securities in accordance with the intended
method of disposition thereof as quickly as practicable, and in connection with
any such request:

               (a) The Company will as expeditiously as practicable prepare and
file with the Commission a registration statement on any form for which the
Company then qualifies or which counsel for the Company shall deem appropriate
and which form shall be available for the sale of the Registrable Securities to
be registered thereunder in accordance with the intended method of distribution
thereof (it being understood that the Company shall use Form S-3 (or any
replacement form) if such form is then available), and use its commercially
reasonable efforts to cause such filed registration statement to become
effective.

               (b) The Company will prepare and file with the Commission 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 and to comply with the provisions of the Securities Act with
respect to the disposition of all securities covered by such registration
statement until such time as all of such securities have been disposed of in
accordance with the intended methods of disposition by the Selling Holder or
Selling Holders thereof set forth in such registration statement.

               (c) The Company will, prior to filing a registration statement or
prospectus or any amendment or supplement thereto, furnish to each Selling
Holder, counsel representing any Selling Holders, and each Underwriter, if any,
of the Registrable Securities covered by such registration statement copies of
such registration statement as proposed to be filed, together with

                                       -8-

exhibits thereto, which documents will be subject to review by the foregoing
within 5 Business Days after delivery, and thereafter furnish to such Selling
Holder, counsel and Underwriter, if any, such number of copies of such
registration statement, each amendment and supplement thereto (in each case
including all exhibits thereto and documents incorporated by reference therein),
the prospectus included in such registration statement (including each
preliminary prospectus) and such other documents as such Selling Holder or
Underwriter may reasonably request in order to facilitate the disposition of the
Registrable Securities owned by such Selling Holder.

               (d) After the filing of the registration statement, the Company
will promptly notify each Selling Holder covered by such registration statement
of any stop order issued or threatened by the Commission and take all reasonable
actions required to prevent the entry of such stop order or to remove it if
entered.

               (e) The Company will use its commercially reasonable efforts to
(i) register or qualify the Registrable Securities under such other securities
or blue sky laws of such jurisdictions in the United States and such other
jurisdictions as any Selling Holder reasonably (in light of such Selling
Holder's intended plan of distribution) requests and (ii) cause such Registrable
Securities to be registered with or approved by such other governmental agencies
or authorities in the United States as may be necessary by virtue of the
business and operations of the Company and do any and all other acts and things
that may be reasonably necessary or advisable to enable such Selling Holder to
consummate the disposition of the Registrable Securities owned by such Selling
Holder; provided that the Company will not be required to (A) qualify generally
to do business in any jurisdiction where it would not otherwise be required to
qualify but for this paragraph (e), (B) subject itself to taxation in any such
jurisdiction or (C) consent to general service of process in any such
jurisdiction.

               (f) The Company will immediately notify each Selling Holder of
such Registrable Securities, at any time when a prospectus relating thereto is
required to be delivered under the Securities Act, of the occurrence of an event
requiring the preparation of a supplement or amendment to such prospectus so
that, as thereafter delivered to the purchasers of such Registrable Securities,
such prospectus will not contain an untrue statement of a material fact or omit
to state any material fact required to be stated therein or necessary to make
the statements therein not misleading, and will promptly make available to each
Selling Holder any such supplement or amendment.

               (g) The Company will enter into customary agreements (including,
if applicable, an underwriting agreement in customary form) and take such other
actions as are reasonably required in order to expedite or facilitate the
disposition of such Registrable Securities in accordance with the intended plan
of distribution of the Selling Holders.

               (h) The Company will deliver promptly to each Selling Holder of
such Registrable Securities and each Underwriter, if any, subject to
restrictions imposed by the United States federal government or any agency or
instrumentality thereof, copies of all correspondence between the Commission and
the Company and its counsel or auditors and all memoranda relating to
discussions with the Commission or its staff with respect to the registration
statement and make available for inspection by any Selling Holder of such
Registrable Securities, any

                                       -9-

Underwriter participating in any disposition pursuant to such registration
statement and any attorney, accountant or other professional retained by any
such Selling Holder or Underwriter (collectively, the "Inspectors"), all
financial and other records, pertinent corporate documents and properties of the
Company (collectively, the "Records"), as shall be reasonably necessary to
enable them to perform a reasonable and customary due diligence investigation,
and cause the Company's officers, directors and employees to supply all
information reasonably requested by any Inspectors in connection with such
registration statement. Records which the Company determines, in good faith, to
be confidential and which it notifies the Inspectors are confidential shall not
be disclosed by the Inspectors unless (i) the disclosure of such Records is
necessary to avoid or correct a misstatement or omission in such registration
statement or (ii) the disclosure or release of such Records is requested or
required pursuant to oral questions, interrogatories, requests for information
or documents or a subpoena or other order from a court of competent jurisdiction
or other process; provided that prior to any disclosure or release pursuant to
clause (ii), the Inspectors shall provide the Company with prompt notice of any
such request or requirement so that the Company may seek an appropriate
protective order or waive such Inspectors' obligation not to disclose such
Records; and provided, further, that if failing the entry of a protective order
or the waiver by the Company permitting the disclosure or release of such
Records, the Inspectors, upon advice of counsel, are compelled to disclose such
Records, the Inspectors may disclose that portion of the Records which counsel
has advised the Inspectors that the Inspectors are compelled to disclose. Each
Selling Holder of such Registrable Securities agrees that it will, upon learning
that disclosure of such Records is sought in a court of competent jurisdiction,
give notice to the Company and allow the Company at its expense, to undertake
appropriate action to prevent disclosure of the Records deemed confidential.

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

               (j) The Company will use its commercially reasonable efforts to
comply with all applicable rules and regulations of the Commission, and make
available to its securityholders, as soon as reasonably practicable, an earnings
statement covering a period of 12 months, beginning within three months after
the effective date of the registration statement, which earnings statement shall
satisfy the provisions of Section 11(a) of the Securities Act and Rule 158
thereunder.

               (k) The Company will use its commercially reasonable efforts (a)
to cause all such Registrable Securities to be listed on a national securities
exchange (if such shares are not already so listed) and on each additional
national securities exchange on which similar securities issued by the Company
are then listed (if any), if the listing of such Registrable Securities is then
permitted under the rules of such exchange or (b) to secure designation of all
such Registrable Securities covered by such registration statement as a NASDAQ
"national market system security" within the meaning of Rule 11Aa2-1 of the
Commission or, failing that, to secure NASDAQ authorization for such Registrable
Securities and, without limiting the generality of the foregoing, to arrange for
at least two market makers to register as such with respect to such Registrable
Securities with the NASD.

                                      -10-

               (l) The Company will appoint a transfer agent and registrar for
all such Registrable Securities covered by such registration statement not later
than the effective date of such registration statement.

               The Company may require each Selling Holder of Registrable
Securities to promptly furnish in writing to the Company such information
regarding the distribution of the Registrable Securities as the Company may from
time to time reasonably request and such other information as may be legally
required in connection with such registration.

               Each Selling Holder agrees that, upon receipt of any notice from
the Company of the happening of any event of the kind described in Section
3.1(f) hereof, such Selling Holder will forthwith discontinue disposition of
Registrable Securities pursuant to the registration statement covering such
Registrable Securities until such Selling Holder's receipt of the copies of the
supplemented or amended prospectus contemplated by Section 3.1(f) hereof, and,
if so directed by the Company such Selling Holder will deliver to the Company
all copies, other than permanent file copies then in such Selling Holder's
possession, of the most recent prospectus covering such Registrable Securities
at the time of receipt of such notice. In the event the Company shall give such
notice, the Company shall extend the period during which such registration
statement shall be maintained effective (including the period referred to in
Section 3.1(a) hereof) by the number of days during the period from and
including the date of the giving of notice pursuant to Section 3.1(f) hereof to
the date when the Company shall make available to the Selling Holders of
Registrable Securities covered by such registration statement a prospectus
supplemented or amended to conform with the requirements of Section 3.1(f)
hereof.

               (m) In connection with the first two (2) underwritten
registrations effected pursuant to Section 2.1 hereof, the Company shall, if
requested by the book running managing Underwriter(s), use its commercially
reasonable efforts to make the Company's senior executives reasonably available
for "road shows" in connection with such offerings. A registration statement
that is withdrawn pursuant to the first two sentences of Section 2.1(f) prior to
the roadshow shall not count as an underwritten registration for purposes of
this paragraph (m).

               Section 3.2. Registration Expenses. In connection with any
registration statement filed pursuant to Section 2.1 or 2.2, the Company shall
pay the following registration expenses incurred in connection with any
registration hereunder (the "Registration Expenses"): (i) all registration and
filing fees, (ii) fees and expenses of compliance with securities or blue sky
laws (including reasonable fees and disbursements of counsel in connection with
blue sky qualifications of the Registrable Securities), (iii) printing expenses,
(iv) the Company's internal expenses (including, without limitation, all
salaries and expenses of its officers and employees performing legal or
accounting duties), (v) fees and expenses incurred in connection with the
listing of the Registrable Securities, (vi) reasonable fees and disbursements of
counsel for the Company and not more than one counsel for the Selling Holders,
as may be chosen by a majority of the Selling Holders, and customary fees and
expenses for independent certified public accountants retained by the Company
(including the expenses of any comfort letters or costs associated with the
delivery by independent certified public accountants of a comfort letter or
comfort letters requested pursuant to Section 3.1(i) hereof) and (vii)
reasonable fees and expenses of any special experts retained by the Company in
connection with such registration.

                                      -11-

The Company shall have no obligation to pay any underwriting fees, discounts or
commissions attributable to the sale of Registrable Securities.

                                   ARTICLE IV
                        INDEMNIFICATION AND CONTRIBUTION

               Section 4.1. Indemnification by the Company. To the fullest
extent permitted by law, the Company agrees to indemnify and hold harmless each
Selling Holder of Registrable Securities, its officers, directors, employees and
agents, and each person, if any, who controls such Selling Holder within the
meaning of the Securities Act from and against any loss, claim, damage or
liability, joint or several, or any action in respect thereof (including, but
not limited to, any loss, claim, damage, liability or action relating to
purchases and sales of Common Stock) to which such Selling Holder, officer,
director, employee or agent or controlling Person may become subject under the
Securities Act or otherwise, insofar as such loss, claim, damage, liability or
action arises out of, or is based upon, (i) any untrue statement or alleged
untrue statement of a material fact contained in any registration statement,
preliminary prospectus or final prospectus or any amendment or supplement
thereto relating to the Registrable Securities or (ii) any omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading and shall reimburse each
Selling Holder and each such officer, director, employee, agent and controlling
Person for any legal and other expenses reasonably incurred by that Selling
Holder, officer, director, employee, agent or controlling Person in connection
with investigating or defending or preparing to defend against any such loss,
claim, damage, liability or action as such expenses are incurred, except insofar
as the same are contained in any information furnished in writing to the Company
by such Selling Holder expressly for use therein; provided, however, that the
Company shall not be liable to any Selling Holder or such Person's directors,
officers, agents or controlling Persons, in any such case for any such loss,
claim, damage or liability to the extent that it arises out of or is based upon
an untrue statement or alleged untrue statement or omission or alleged omission
made in connection with such registration statement, preliminary prospectus,
final prospectus or amendments or supplements thereto, in conformity with
written information relating to such Selling Holder furnished to the Company by
such Selling Holder expressly for inclusion therein in connection with such
registration; and, provided, further, that as to any preliminary prospectus or
any final prospectus, this indemnity agreement shall not inure to the benefit of
any Selling Holder or such Person's directors, officers, agents or controlling
Persons, on account of any loss, claim, damage or liability arising from the
sale of Registrable Securities to any Person by such Selling Holder if such
Selling Holder or its representatives failed to send or give a copy of the final
prospectus or a prospectus supplement, as the case may be (excluding documents
incorporated by reference therein), as the same may be amended or supplemented,
to that Person within the time required by the Securities Act, and the untrue
statement or alleged untrue statement of a material fact or omission or alleged
omission to state a material fact in such preliminary prospectus or final
prospectus was corrected in the final prospectus or such prospectus supplement,
as the case may be (excluding documents incorporated by reference therein),
unless such failure resulted from the non-compliance by the Company with Section
3.1(f). The Company also agrees to indemnify any Underwriters of the Registrable
Securities, their officers and directors and each Person who controls such
Underwriters on substantially the same basis as that of the indemnification of
the Selling Holders provided in this Section 4.1. The

                                      -12-

indemnities provided by this Section 4.1 shall remain in full force and effect
regardless of any investigation made by or on behalf of such Selling Holder or
Underwriter.

               Section 4.2. Indemnification by Holders of Registrable
Securities. To the fullest extent permitted by law, each Selling Holder agrees,
severally but not jointly, to indemnify and hold harmless the Company its
officers, directors and agents and each Person, if any, who controls the Company
within the meaning of the Securities Act to the same extent as the indemnity
from the Company to such Selling Holder pursuant to clauses (i) and (ii) of
Section 4.1, but only with reference to information related to such Selling
Holder furnished in writing by such Selling Holder or on such Selling Holder's
behalf expressly for use in any registration statement or prospectus relating to
the Registrable Securities, or any amendment or supplement thereto, or any
preliminary prospectus; provided that the obligation to indemnify will be
individual to each Selling Holder and will be limited to the net amount of
proceeds received by such Selling Holder from the sale of Registrable Securities
pursuant to such Registration Statement. Each Selling Holder also agrees to
indemnify and hold harmless Underwriters of the Registrable Securities, their
officers and directors and each Person who controls such Underwriters on
substantially the same basis as that of the indemnification of the Company
provided in this Section 4.2, subject to the proviso in the first sentence of
this Section 4.2. Notwithstanding the foregoing, the indemnity set forth in this
Section 4.2, shall not apply to amounts paid in settlements effected without the
consent of such Selling Holder (which consent shall not be unreasonably withheld
or delayed).

               Section 4.3. Conduct of Indemnification Proceedings. Promptly
after receipt by any person in respect of which indemnity may be sought pursuant
to Section 4.1 or 4.2 (an "Indemnified Party") of notice of any claim or the
commencement of any action, the Indemnified Party shall, if a claim in respect
thereof is to be made against the person against whom such indemnity may be
sought (an "Indemnifying Party") notify the Indemnifying Party in writing of the
claim or the commencement of such action, provided that the failure to notify
the Indemnifying Party shall not relieve it from any liability which it may have
to an Indemnified Party otherwise than under Section 4.1 or 4.2, except to the
extent of any actual prejudice resulting therefrom. If any such claim or action
shall be brought against an Indemnified Party, and it shall notify the
Indemnifying Party thereof, the Indemnifying Party shall be entitled to
participate therein, and, to the extent that it wishes, jointly with any other
similarly notified Indemnifying Party, to assume the defense thereof with
counsel satisfactory to the Indemnified Party. After notice from the
Indemnifying Party to the Indemnified Party of its election to assume the
defense of such claim or action, the Indemnifying Party shall not be liable to
the Indemnified Party for any legal or other expenses subsequently incurred by
the Indemnified Party in connection with the defense thereof other than
reasonable costs of investigation; provided that the Indemnified Party shall
have the right to employ separate counsel to represent the Indemnified Party and
its controlling Persons who may be subject to liability arising out of any claim
in respect of which indemnity may be sought by the Indemnified Party against the
Indemnifying Party, but the fees and expenses of such counsel shall be for the
account of such Indemnified Party unless (i) the Indemnifying Party and the
Indemnified Party shall have mutually agreed to the retention of such counsel or
(ii) in the reasonable judgment of such Indemnified Party representation of both
parties by the same counsel would be inappropriate due to actual or potential
differing interests between them. No Indemnifying Party shall, without the prior
written consent of the Indemnified Party, effect any settlement of any claim or
pending or

                                      -13-

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

               Section 4.4. Contribution. If the indemnification provided for in
this Article IV is unavailable to the Indemnified Parties in respect of any
losses, claims, damages, liabilities or expenses referred to herein, then each
such Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall
contribute to the amount paid or payable by such Indemnified Party as a result
of such losses, claims, damages, liabilities or expenses (i) as between the
Company and the Selling Holders on the one hand and the Underwriters on the
other, in such proportion as is appropriate to reflect the relative benefits
received by the Company and the Selling Holders on the one hand and the
Underwriters on the other from the offering of the Registrable Securities, or if
such allocation is not permitted by applicable law, in such proportion as is
appropriate to reflect not only the relative benefits but also the relative
fault of the Company and the Selling Holders on the one hand and of the
Underwriters on the other in connection with the statements or omissions which
resulted in such losses, claims, damages or liabilities, as well as any other
relevant equitable considerations and (ii) as between the Company on the one
hand and each Selling Holder on the other, in such proportion as is appropriate
to reflect the relative fault of the Company and of each Selling Holder in
connection with such statements or omissions, as well as any other relevant
equitable considerations. The relative benefits received by the Company and the
Selling Holders on the one hand and the Underwriters on the other shall be
deemed to be in the same proportion as the total proceeds from the offering (net
of underwriting discounts and commissions but before deducting expenses)
received by the Company and the Selling Holders bear to the total underwriting
discounts and commissions received by the Underwriters, in each case as set
forth in the table on the cover page of the prospectus. The relative fault of
the Company and the Selling Holders on the one hand and of the Underwriters on
the other shall be determined by reference to, among other things, whether the
untrue or alleged untrue statement of a material fact or the omission or alleged
omission to state a material fact relates to information supplied by the Company
and the Selling Holders or by the Underwriters. The relative fault of the
Company on the one hand and of each Selling Holder on the other shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to state
a material fact relates to information supplied by such party, and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such statement or omission.

               The Company and the Selling Holders agree that it would not be
just and equitable if contribution pursuant to this Section 4.4 were determined
by pro rata allocation (even if the Underwriters were treated as one entity for
such purpose) or by any other method of allocation which does not take account
of the equitable considerations referred to in the immediately preceding
paragraph. The amount paid or payable by an Indemnified Party as a result of the
losses, claims, damages or liabilities referred to in the immediately preceding
paragraph shall be deemed to include, subject to the limitations set forth
above, any legal or other expenses reasonably incurred by such Indemnified Party
in connection with investigating or defending any such action or claim.
Notwithstanding the provisions of this Section 4.4, no Underwriter shall be
required to contribute any amount in excess of the amount by which the total
price at which the Registrable Securities underwritten by it and distributed to
the public

                                      -14-

were offered to the public exceeds the amount of any damages which such
Underwriter has otherwise been required to pay by reason of such untrue or
alleged untrue statement or omission or alleged omission, and no Selling Holder
shall be required to contribute any amount in excess of the amount by which the
total price at which the Registrable Securities of such Selling Holder were
offered to the public (less underwriting discounts and commissions) exceeds the
amount of any damages which such Selling Holder has otherwise been required to
pay by reason of such untrue or alleged untrue statement or omission or alleged
omission. No person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the Securities Act) shall be entitled to contribution from
any person who was not guilty of such fraudulent misrepresentation. Each Selling
Holder's obligations to contribute pursuant to this Section 4.4 are several in
proportion to the proceeds of the offering received by such Selling Holder and
not joint.

                                    ARTICLE V
                                  MISCELLANEOUS

               Section 5.1. Participation in Underwritten Registrations. No
Person may participate in any underwritten registration hereunder unless such
Person (a) agrees to sell such Person's securities on the basis provided in any
underwriting arrangements approved by the Persons entitled hereunder to approve
such arrangements and (b) completes and executes all questionnaires, powers of
attorney, indemnities, underwriting agreements and other documents reasonably
required under the terms of such underwriting arrangements and these
Registration Rights.

               Section 5.2. Rule 144. The Company covenants that it will file
any reports required to be filed by it under the Securities Act and the Exchange
Act and that it will take such further action as any Holder may reasonably
request, all to the extent required from time to time to enable Holders to sell
Registrable Securities without registration under the Securities Act within the
limitation of the exemptions provided by (a) Rule 144 under the Securities Act,
as such Rules may be amended from time to time, or (b) any similar rule or
regulation hereafter adopted by the Commission. Upon the request of any Holder,
the Company will deliver to such Holder a written statement as to whether it has
complied with such requirements.

               Section 5.3. Holdback Agreements. If any registration hereunder
shall be in connection with an underwritten public offering, each Holder of
Registrable Securities agrees not to effect any sale or distribution of the
securities being registered or of a similar security of the Company or any
securities convertible into or exchangeable or exercisable for such securities,
including a sale pursuant to Rule 144 under the Securities Act, during the 14
days prior to, and during (i) the 180-day period beginning on the consummation
of the Initial Public Offering, unless the investment banks or underwriters
managing the public offering otherwise agree, and (ii) the 90-day period
beginning on, the effective date of any other public offering to be underwritten
on a firm commitment basis (except as part of such underwritten registration),
unless the investment banks or underwriters managing the public offering
otherwise agree.

               Section 5.4. Other Registration Rights. Notwithstanding anything
contained in this Agreement to the contrary, no provision herein or therein
shall be interpreted to limit (i) the right of the Company to grant to any other
Person any right of registration in respect of any securities of the Company
(provided, however, that the Company shall not enter into any

                                      -15-

agreement with respect to the Registrable Securities which would prevent the
Company from complying with its obligations under this Agreement) or (ii) the
number of times the Company may grant any such right of registration under the
Securities Act to any Person.

               Section 5.5. No Inconsistent Agreements. The Company will not
hereafter enter into any agreement with respect to its securities which is
inconsistent with the rights granted to the Holders in this Agreement.

               Section 5.6. Successors and Assigns. This Agreement shall be
binding upon and shall inure to the benefit of the parties hereto, and their
respective successors and permitted assigns.

               Section 5.7. No Waivers, Amendments. (a) Except as expressly set
forth herein, no failure or delay by any party in exercising any right, power or
privilege hereunder shall operate as a waiver thereof, nor shall any single or
partial exercise thereof preclude any other or further exercise thereof or the
exercise of any other right, power or privilege. The rights and remedies herein
provided shall be cumulative and not exclusive of any rights or remedies
provided by law.

               (b) Any amendment, modification or supplement to this Agreement
shall not be enforced against any party hereto unless such amendment,
modification or supplement is signed by the Company and each of the Holders.

               (c) Any provision of this Agreement may be waived if, but only
if, such waiver is in writing and is signed by the party against whom the
enforcement of such waiver is sought.

               Section 5.8. Notices. All notices, requests and other
communications to any party hereunder shall be in writing (including telex,
telecopier or similar writing) and shall be given to such party at its address
or telecopier number set forth below, or such other address or telecopier number
as such party may hereinafter specify for the purpose to the party giving such
notice. Each such notice, request or other communication shall be effective (a)
if given by telecopy, when such telecopy is transmitted to the telecopy number
specified in this Section and the appropriate answerback is received or, (b) if
given by overnight courier or express mail service, when delivery is confirmed
or, (c) if given by any other means, when delivered at the address specified in

               Section 5.9. Term of Agreement. This Agreement shall terminate at
such time as the Holders cease to beneficially own any Registrable Securities;
provided that any termination pursuant to this Section 5.9 will not relieve any
party for any liability arising from a breach of representation, warranty,
covenant or agreement occurring prior to such termination.

               SECTION 5.10. GOVERNING LAW; SUBMISSION TO JURISDICTION. THIS
AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN

                                      -17-

ACCORDANCE WITH THE LAWS OF THE STATE OF DELAWARE. Each of the parties hereto
hereby (a) submits to the jurisdiction of the courts of the State of Delaware
and the United States District Court for the District of Delaware with respect
to matters arising out of or relating hereto, (b) agrees that all claims with
respect to such matters may be heard and determined in an action or proceeding
in such Delaware courts, and (c) agrees that a final judgment in any such action
or proceeding will be conclusive and may be enforced in other jurisdictions by
suit on the judgment or in any other manner provided by law.

               Section 5.11. Section Headings. The section headings contained in
this Agreement are for reference purposes only and shall not affect the meaning
or interpretation of this Agreement.

               Section 5.12. Entire Agreement. This Agreement constitutes the
entire agreement and understanding among the parties hereto and supersedes any
and all prior agreements and understandings (including without limitation, the
Original Agreement), written or oral, relating to the subject matter hereof.

               Section 5.13. Severability. Any term or provision of this
Agreement which is invalid or unenforceable in any jurisdiction shall, as to
such jurisdiction, be ineffective to the extent of such invalidity or
unenforceability without rendering invalid or unenforceable the remaining terms
and provisions of this Agreement or affecting the validity or enforceability of
any of the terms or provisions of this Agreement in any other jurisdictions, it
being intended that all rights and obligations of the parties hereunder shall be
enforceable to the fullest extent permitted by law.

               Section 5.14. Counterparts. This Agreement may be signed in
counterparts, each of which shall constitute an original and which together

any of the parties hereto without the prior written consent of the other
parties.

hereto agree that irreparable damage would occur in the event that any of the
provisions of this Agreement were not performed in accordance with their
specific terms. It is accordingly agreed that the parties shall be entitled to
specific performance of the terms hereof, this being in addition to any other
remedy to which they are entitled at law or in equity.

               (b) The parties hereto agree to execute, acknowledge, deliver,
file and record such further certificates, amendments, instruments, agreements
and documents, and to do all such other acts and things, as may be required by

this Agreement.
