authorizations conferred on the Committee by the Plan, the Committee shall

determine the type or types of Awards to be granted to a Participant; (iii)
determine the number of Shares to be covered by, or with respect to which
payments, rights, or other matters are to be calculated in connection with,
Awards; (iv) determine the terms and conditions of any Award; (v) determine
whether, to what extent, and under what circumstances Awards may be
settled, or exercised in cash, Shares, other securities, other Awards or
other property, or canceled, forfeited, or suspended and the method or
methods by which Awards may be settled, exercised, canceled, forfeited, or
suspended; (vi) determine whether, to what extent, and under what

or any Affiliate, or to a committee of such officers or managers, the
authority, subject to such terms and limitations as the Committee shall

respect to, or to alter, discontinue, suspend, or terminate Awards held by,
Participants who are not officers or directors of the Company for purposes
of Section 16 or who are otherwise not subject to Section 16.

(d) No Liability. No member of the Board or Committee shall be liable for
any action taken or determination made in good faith with respect to the
Plan or any Award granted hereunder.

SECTION 4.

SHARES AVAILABLE FOR AWARDS.

(a) Shares Available. Subject to adjustment as provided in Section 4(b),
the number of Shares with respect to which Awards may be granted under the
Plan shall be 20,000,000 and the number of Shares with respect to which
Awards (other than Options) may be granted under the Plan shall be
2,500,000. If, after the effective date of the Plan, any Shares covered by
an Award granted under the Plan, or to which such an Award relates, are
forfeited, or if such an Award is settled for cash or otherwise terminates
or is canceled without the delivery of Shares, then the Shares covered by
such Award, or to which such Award relates, or the number of Shares
otherwise counted against the aggregate number of Shares with respect to
which Awards may be granted, to the extent of any such settlement,
forfeiture, termination or cancellation, shall again become Shares with
respect to which Awards may be granted. In the event that any Option or
other Award granted hereunder is exercised through the delivery of Shares
or in the event that withholding tax liabilities arising from such Award
are satisfied by the withholding of Shares by the Company, the number of
Shares available for Awards under the Plan shall be increased by the number
of Shares so surrendered or withheld. Notwithstanding the foregoing and
subject to adjustment as provided in Section 4(b), from and after the date
that the Plan is intended to comply with the requirements of Section
162(m), no Participant may receive Awards under the Plan in any calendar
year that relate to more than 1,000,000 Shares, except during the first
year of the Plan, in which case no Participant may receive Awards that
relate to more than 2,000,000 Shares.

(b) Adjustments. In the event that the Committee determines that any
dividend or other distribution (whether in the form of cash, Shares, other
securities, or other property), recapitalization, stock split, reverse
stock split, reorganization, merger, consolidation, split-up, spin-off,
combination, repurchase, or exchange of Shares or other securities of the
Company, issuance of warrants or other rights to purchase Shares or other
securities of the Company, or other similar corporate transaction or event
affects the Shares such that an adjustment is determined by the Committee
to be appropriate in order to prevent dilution or enlargement of the
benefits or potential benefits intended to be made available under the
Plan, then the Committee shall, in such manner as it may deem equitable:
(i) adjust any or all of (A) the number of Shares or other securities of
the Company (or number and kind of other securities or property) with
respect to which Awards may be granted, (B) the maximum number of Shares
subject to an Award granted to a Participant pursuant to Section 4(a), (C)
the number of Shares or other securities of the Company (or number and kind
of other securities or property) subject to outstanding Awards, and (D) the
grant or exercise price with respect to any Award; (ii) if deemed
appropriate, provide for an equivalent award in respect of securities of
the surviving entity of any merger, consolidation or other transaction or
event having a similar effect; or (iii) if deemed appropriate, make
provision for a cash payment to the holder of an outstanding Award;
provided, in each case, that, unless otherwise determined by the Committee,
(A) with respect to Awards of Incentive Stock Options no such adjustment
shall be authorized to the extent that such authority would cause the Plan
to violate Section 422(b)(1) of the Code, as from time to time amended, and
(B) with respect to any Award no such adjustment shall be authorized to the
extent that such authority would be inconsistent with the Plan's meeting
the requirements of Section 162(m).

(c) Substitute Awards. Any Shares underlying Substitute Awards shall not be
counted against the Shares available for Awards under the Plan.

(d) Sources of Shares Deliverable Under Awards. Any Shares delivered
pursuant to an Award may consist, in whole or in part, of authorized and
unissued Shares or of treasury Shares.

SECTION 5.

ELIGIBILITY.  Any Eligible Recipient shall be eligible to be designated a
Participant.

SECTION 6.

STOCK OPTIONS.

(a) Grant. Subject to the provisions of the Plan, the Committee shall have
sole and complete authority to determine the Participants to whom Options
shall be granted, the number of Shares to be covered by each Option, the
option price and the conditions and limitations applicable to the exercise
of the Option. The Committee shall have the authority to grant Incentive
Stock Options, or to grant Non-Qualified Stock Options, or to grant both
types of options; provided that only employees of the Company or any Parent
or Subsidiary may be granted Incentive Stock Options. In the case of
Incentive Stock Options, the terms and conditions of such grants shall be
subject to and comply with such rules as may be prescribed by Section 422
of the Code, as from time to time amended, and any regulations implementing
such statute.

(b) Exercise Price. The Committee in its sole discretion shall establish
the exercise price at the time each Option is granted. Except in the case
of Substitute Awards, the exercise price of an Option may not be less than
the Fair Market Value on the date of grant of such Option.

(c) Exercise. Each Option shall be exercisable at such times and subject to
such terms and conditions as the Committee may, in its sole discretion,
specify in the applicable Award Agreement or thereafter. The Committee may
impose such conditions with respect to the exercise of options, including
without limitation, any relating to the application of federal, state or
foreign securities laws or the Code, as it may deem necessary or advisable;
provided that (to the extent required at the time of grant by California
"blue sky" laws), Options granted to individuals other than officers,
directors or consultants of the Company shall be exercisable at the rate of
at least 20% per year over five years from the date of grant.
Notwithstanding the foregoing, an Option shall not be exercisable after the
expiration of 10 years from the date such Option was granted.

(d) Early Exercise. The Committee may provide at the time of grant or any
time thereafter, in its sole discretion, that any Option shall be
exercisable that otherwise would not then be exercisable, provided that, in
connection with such exercise, the Participant enters into a form of
Restricted Stock Award Agreement approved by the Committee.

(e) Payment. No Shares shall be delivered pursuant to any exercise of an
Option until payment in full of the option price is received by the
Company. Such payment may be made in cash, or its equivalent, or by
exchanging Shares owned by the Participant for at least six months (which
are not the subject of any pledge or other security interest), or through
any broker's cashless exercise procedure approved by the Committee, or by a
combination of the foregoing, provided that the combined value of all cash
and cash equivalents and the Fair Market Value of any such Shares so
tendered to the Company as of the date of such tender is at least equal to
such option price.

(f) Restoration Options. In the event that any Participant delivers Shares
in payment of the exercise price of any Option granted hereunder in
accordance with paragraph (e) above, the Committee shall have the authority
to grant or provide for the automatic grant of a Restoration Option to such
Participant. A Restoration Option shall entitle the Participant to purchase
a number of Shares equal to the number of Shares delivered upon exercise of
the original Option and, in the discretion of the Committee, the number of
shares, if any, tendered to the Company to satisfy any withholding tax
liability arising in connection with the exercise of the original Option. A
Restoration Option shall have a per share exercise price of not less than
100% of the Fair Market Value of a Share on the date of grant of such
Restoration Option, a term not longer than the remaining term of the
original Option at the time of exercise thereof, and such other terms and
conditions (including provisions relating to forfeiture of such Restoration
Options in the event that specified share ownership is not maintained) as
the Committee in its sole discretion shall determine.

SECTION 7.

RESTRICTED STOCK AND RESTRICTED STOCK UNITS.

(a) Grant. Subject to the provisions of the Plan, the Committee shall have
sole and complete authority to determine the Participants to whom Shares of
Restricted Stock and Restricted Stock Units shall be granted, the number of
Shares of Restricted Stock and/or the number of Restricted Stock Units to
be granted to each Participant, the duration of the period during which,
and the conditions under which, the Restricted Stock and Restricted Stock
Units may be forfeited to the Company, and the other terms and conditions
of such Awards. Notwithstanding the foregoing (to the extent required at
the time of grant by California "blue sky" laws), the purchase price per
share of Restricted Stock, if any, shall not be less than 85% of the Fair
Market Value per Share (100% in the case of 10% stockholders) on such date
or at the time the purchase is consummated.

(b) Transfer Restrictions. Shares of Restricted Stock and Restricted Stock
Units may not be sold, assigned, transferred, pledged or otherwise
encumbered, except, in the case of Restricted Stock, as provided in the
Plan or the applicable Award Agreements. Certificates issued in respect of
Shares of Restricted Stock shall be registered in the name of the
Participant and deposited by such Participant, together with a stock power
endorsed in blank, with the Company. Upon the lapse of the restrictions
applicable to such Shares of Restricted Stock, the Company shall deliver
such certificates to the Participant or the Participant's legal
representative.

(c) Payment. Each Restricted Stock Unit shall have a value equal to the
Fair Market Value of a Share. Restricted Stock Units shall be paid in cash,
Shares, other securities or other property, as determined in the sole
discretion of the Committee, upon the lapse of the restrictions applicable
thereto, or otherwise in accordance with the applicable Award Agreement.

(d) Dividends and Distributions. Dividends and other distributions paid on
or in respect of Restricted Stock or Restricted Stock Units may be paid
directly to the Participant, or may be reinvested in additional Shares of
Restricted Stock or in additional Restricted Stock Units, as determined by
the Committee in its sole discretion.

SECTION 8.

OTHER STOCK-BASED AWARDS. The Committee shall have authority to grant to
Participants an Other Stock-Based Award, which shall consist of any right
that is (i) not an Award described in Sections 6 or 7 above and (ii) an
Award of Shares or an Award denominated or payable in, valued in whole or
in part by reference to, or otherwise based on or related to, Shares
(including, without limitation, securities convertible into Shares), as
deemed by the Committee to be consistent with the purposes of the Plan.
Subject to the terms of the Plan and any applicable Award Agreement, the
Committee shall determine the terms and conditions of any such Other
Stock-Based Award.

SECTION 9.

TERMINATION OF EMPLOYMENT/SERVICE. The Committee shall have the full power
and authority to determine the terms and conditions that shall apply to any
Award upon a termination of employment/service, including a termination by
the Company without Cause, by a Participant voluntarily, or by reason of
death, Disability or Retirement. In addition, prior to the termination of
all transfer restrictions applicable to the Shares described in the Private
Placement Memorandum dated March 10, 2000, upon a termination of
employment/service the Company shall have a repurchase right with respect
to any Shares acquired upon exercise or settlement of an Award equal to the
Fair Market Value on the date of repurchase.

SECTION 10.

CHANGE IN CONTROL. Upon a Change in Control occurring, all Awards of
Options or Restricted Stock that would otherwise have become vested in the
one-year period following the Change in Control had the Participant
remained employed during that one year period shall vest immediately, and
in the case of such vested Awards that are Options, become exercisable in
accordance with their terms. In the event that the employment of the
Participant is terminated by the Company other than for Cause within the
one year period following the Change in Control, or in such other
circumstances as provided in the Award, all other remaining Awards of
Options or Restricted Stock, as the case may be, shall vest immediately
upon such a termination and, in the case of such vested Awards that are
Options, become immediately exercisable in accordance with their terms.

SECTION 11.

AMENDMENT AND TERMINATION.

(a) Amendments to the Plan. The Board may amend, alter, suspend,
discontinue, or terminate the Plan or any portion thereof at any time;
provided that no such amendment, alteration, suspension, discontinuation or
termination shall be made without requisite stockholder approval if such
approval is necessary to comply with any tax or regulatory requirement for
which or with which the Board deems it necessary or desirable to comply. In
addition, the Committee may amend the Plan or any portion thereof at any
time to (i) cure any ambiguity or to correct or supplement any provision of
the Plan which may be defective or inconsistent with any other provision of
the Plan or (ii) make any other provisions in regard to matters or
questions arising under the Plan which the Committee may deem necessary or
desirable and which, in the judgment of the Committee, is not material;
provided that no such amendment shall be made without requisite stockholder
approval if such approval is necessary to comply with any tax or regulatory
requirement for which or with which the Board or the Committee deems it
necessary or desirable to comply.

(b) Amendments to Awards. The Committee may waive any conditions or rights
under, amend any terms of, or alter, suspend, discontinue, cancel or
terminate, any Award theretofore granted, prospectively or retroactively;
provided that any such waiver, amendment, alteration, suspension,
discontinuance, cancellation or termination that would adversely affect the
rights of any Participant or any holder or beneficiary of any Award
theretofore granted shall not to that extent be effective without the
consent of the affected Participant, holder, or beneficiary; and provided
further that the Committee shall not have the power to amend the terms of
previously granted Awards to reduce, or cancel such Awards and grant
substitute Awards which would have the effect of reducing the exercise
price except pursuant to paragraph (c) below.

(c) Adjustment of Awards upon the Occurrence of Certain Unusual or
Nonrecurring Events. The Committee is hereby authorized to make adjustments
in the terms and conditions of, and the criteria included in, Awards in
recognition of unusual or nonrecurring events (including, without
limitation, the events described in Section 4(b) hereof) affecting the
Company, any Affiliate, or the financial statements of the Company or any
Affiliate, or of changes in applicable laws, regulations, or accounting
principles, whenever the Committee determines that such adjustments are
appropriate in order to prevent dilution or enlargement of the benefits or
potential benefits intended to be made available under the Plan; provided
that, unless otherwise determined by the Committee, no such adjustment
shall be authorized to the extent that such authority would be inconsistent
with the Plan's meeting the requirements of Section 162(m) to the extent
Section 162(m) applies to an Award.

SECTION 12.

GENERAL PROVISIONS.

(a) Dividend Equivalents. In the sole and complete discretion of the
Committee, an Award may provide the Participant with dividends or dividend
equivalents, payable in cash, Shares, other securities or other property on
a current or deferred basis.

(b) Transferability. Except as provided below, no Award shall be assigned,
alienated, pledged, attached, sold or otherwise transferred or encumbered
by a Participant, except by will or the laws of descent and distribution.
Notwithstanding the foregoing, a Participant may transfer any vested Award,
other than an Incentive Stock Option, to members of his or her immediate
family (defined as his or her spouse, children or grandchildren) or to one
or more trusts for the exclusive benefit of such immediate family members
or partnerships in which such immediate family members are the only
partners if the Award Agreement so provides, the transfer is approved by
the Committee and the Participant does not receive any consideration for
the transfer. Any such transferred Award shall continue to be subject to
the same terms and conditions that were applicable to such Award
immediately prior to its transfer (except that such transferred Award shall
not be further transferable by the transferee).

(c) No Rights to Awards. No Person shall have any claim to be granted any
Award, and there is no obligation for uniformity of treatment of Employees,
Non-Employee Directors, consultants, Participants, or holders or
beneficiaries of Awards. The terms and conditions of Awards need not be the
same with respect to each recipient.

(d) Share Certificates. All certificates for Shares or other securities of
the Company or any Affiliate delivered under the Plan pursuant to any Award
or the exercise thereof shall be subject to such stop transfer orders and
other restrictions as the Committee may deem advisable under the Plan or
the rules, regulations, and other requirements of the SEC, any stock
exchange or interdealer market system upon which such Shares or other
securities are then listed, and any applicable federal or state laws, and
the Committee may cause a legend or legends to be put on any such
certificates to make appropriate reference to such restrictions.

(e) Stockholders Agreement. The Committee may require that a Participant,
as a condition of the grant or exercise of an Award, execute a stockholders
agreement containing terms and conditions generally applicable to some or
all of the stockholders of the Company.

(f) Withholding. A participant may be required to pay to the Company or any
Affiliate and the Company or any Affiliate shall have the right and is
hereby authorized to withhold from any Award, from any payment due or
transfer made under any Award or under the Plan or from any compensation or
other amount owing to a Participant the amount (in cash, Shares, other
securities, other Awards or other property) of any applicable withholding
or other taxes in respect of an Award, its exercise, or any payment or
transfer under an Award or under the Plan and to take such other action as
may be necessary in the opinion of the Company to satisfy all obligations
for the payment of such taxes. The Committee may provide in an Award
Agreement that a Participant can satisfy the foregoing requirement by
electing to have the Company withhold Shares having a Fair Market Value
equal to the minimum amount of tax required to be withheld.

(g) Award Agreements. Each Award hereunder shall be evidenced by an Award
Agreement that shall be delivered to the Participant and shall specify the
terms and conditions of the Award and any rules applicable thereto. In the
event of a conflict between the terms of the Plan and any Award Agreement,
the terms of the Award Agreement shall prevail.

(h) No Limit on Other Compensation Arrangements. Nothing contained in the
Plan shall prevent the Company or any Affiliate from adopting or continuing
in effect other compensation arrangements, which may, but need not, provide
for the grant of options, restricted stock, Shares and other types of
Awards provided for hereunder (subject to stockholder approval if such
approval is required), and such arrangements may be either generally
applicable or applicable only in specific cases.

(i) No Right to Employment. The grant of an Award shall not be construed as
giving a Participant the right to be retained in the employ of the Company
or any Affiliate. Further, the Company or an Affiliate may at any time
dismiss a Participant from employment, free from any liability or any claim
under the Plan, unless otherwise expressly provided in the Plan or in any
Award Agreement.

(j) No Rights as Stockholder. Subject to the provisions of the applicable
Award, no Participant or holder or beneficiary of any Award shall have any
rights as a stockholder with respect to any Shares to be distributed under
the Plan until he or she has become the holder of such Shares.
Notwithstanding the foregoing, in connection with each grant of Restricted
Stock hereunder, the applicable Award shall specify if and to what extent
the Participant shall not be entitled to the rights of a stockholder in
respect of such Restricted Stock.

(k) Governing Law. The validity, construction, and effect of the Plan and
any rules and regulations relating to the Plan and any Award Agreement
shall be determined in accordance with the laws of the State of Delaware
without giving effect to the conflict of law principles thereof.

(l) Severability. If any provision of the Plan or any Award is or becomes
or is deemed to be invalid, illegal, or unenforceable in any jurisdiction
or as to any Person or Award, or would disqualify the Plan or any Award
under any law deemed applicable by the Committee, such provision shall be
construed or deemed amended to conform to the applicable laws, or if it
cannot be construed or deemed amended without, in the determination of the
Committee, materially altering the intent of the Plan or the Award, such
provision shall be stricken as to such jurisdiction, Person or Award and
the remainder of the Plan and any such Award shall remain in full force and
effect.

(m) Other Laws. The Committee may refuse to issue or transfer any Shares or
other consideration under an Award if, acting in its sole discretion, it
determines that the issuance or transfer of such Shares or such other
consideration might violate any applicable law or regulation or entitle the
Company to recover the same under Section 16(b) of the Exchange Act, and
any payment tendered to the Company by a Participant, other holder or
beneficiary in connection with the exercise of such Award shall be promptly
refunded to the relevant Participant, holder, or beneficiary. Without
limiting the generality of the foregoing, no Award granted hereunder shall
be construed as an offer to sell securities of the Company, and no such
offer shall be outstanding, unless and until the Committee in its sole
discretion has determined that any such offer, if made, would be in
compliance with all applicable requirements of the U.S. federal or non-U.S.
securities laws and any other laws to which such offer, if made, would be
subject.

(n) No Trust or Fund Created. Neither the Plan nor any Award shall create
or be construed to create a trust or separate fund of any kind or a
fiduciary relationship between the Company or any Affiliate and a
Participant or any other Person. To the extent that any Person acquires a
right to receive payments from the Company or any Affiliate pursuant to an
Award, such right shall be no greater than the right of any unsecured
general creditor of the Company or any Affiliate.

(o) No Fractional Shares. No fractional Shares shall be issued or delivered
pursuant to the Plan or any Award, and the Committee shall determine
whether cash, other securities, or other property shall be paid or
transferred in lieu of any fractional Shares or whether such fractional
Shares or any rights thereto shall be canceled, terminated or otherwise
eliminated.

(p) Headings. Headings are given to the Sections and subsections of the
Plan solely as a convenience to facilitate reference. Such headings shall
not be deemed in any way material or relevant to the construction or
interpretation of the Plan or any provision thereof.

(q) Information Provided to Participants. The Company shall provide
financial statements to Participants at least annually and such other
information as may be required by law.

SECTION 13.

TERM OF THE PLAN.

(a) Effective Date. The Plan shall be effective as of December 5, 2000.

(b) Expiration Date. No new Awards shall be granted under the Plan after
the tenth anniversary of the Effective Date. Unless otherwise expressly
provided in the Plan or in an applicable Award Agreement, any Award granted
hereunder may, and the authority of the Board or the Committee to amend,
alter, adjust, suspend, discontinue, or terminate any such Award or to
waive any conditions or rights under any such Award shall, continue after
the authority for grant of new Awards hereunder has been exhausted.Exhibit 10.9

         The Issuer represents and warrants to each Purchaser as follows:

corporation duly incorporated, validly existing and in good standing under
the laws of its jurisdiction of incorporation and has all corporate powers
and all material governmental licenses, authorizations, permits, consents
and approvals required to carry on its business as now conducted. The
Issuer is duly qualified to do business as a foreign corporation and is in
good standing in each jurisdiction where such qualification is necessary,
except for those jurisdictions where failure to be so qualified would not,
individually or in the aggregate, have a Material Adverse Effect. The
Issuer has heretofore delivered to the Purchasers true and complete copies
of the certificate of incorporation and bylaws of the Issuer as currently
in effect.

         SECTION 3.02. Corporate Authorization. The execution, delivery and
performance by Issuer of this Agreement and the consummation of the
transactions contemplated hereby are within the Issuer's corporate powers
and have been duly authorized by all necessary corporate action on the part
of the Issuer. This Agreement constitutes a valid and binding agreement of
the Issuer, and the Securities when issued will constitute valid and
binding obligations of the Issuer. The shares of Common Stock issuable upon
conversion of the Securities will, when issued, be validly issued, fully
paid and nonassessable, free and clear of any Lien and free of any other
restriction or limitation (including any restriction on the right to vote,
sell or otherwise dispose of such shares of Common Stock) except as
provided under applicable securities laws or as set forth in the
Securityholders Agreement and the Issuer's certificate of incorporation and
bylaws.

         SECTION 3.03. Governmental Authorization. The execution, delivery
and performance by the Issuer of this Agreement and the consummation of the
transactions contemplated hereby require no action by or in respect of, or
filing with, any governmental body, agency or official other than (i)
compliance with any applicable requirements of the HSR Act; (ii) approval
of the Charter Amendment by the Commission; and (iii) such other actions or
filings which have been taken or made or shall be taken or made on or prior
to the Closing Date.

         SECTION 3.04. Noncontravention. The execution, delivery and
performance by the Issuer of this Agreement and the consummation of the
transactions contemplated hereby do not and will not (i) violate the
certificate of incorporation or bylaws of the Issuer or any of its
Subsidiaries, (ii) assuming compliance with the matters referred to in
Section 3.03, violate any applicable law, rule, regulation, judgment,
injunction, order or decree, (iii) require any consent or other action by
any Person under, constitute a default under, or give rise to any right of
termination, cancellation or acceleration of any right or obligation of the
Issuer or any of its Subsidiaries or to a loss of any benefit to which the
Issuer or any of its Subsidiaries is entitled under any provision of any
material agreement or other instrument binding upon the Issuer or any of
its Subsidiaries or (iv) result in the creation or imposition of any Lien
on any asset of the Issuer or any of its Subsidiaries.

30,000,000 shares of Preferred Stock. As of the date hereof, there are (i)

Stock) granted under the Issuer's equity incentive plan. As of the date
hereof, the NASD owns 95,454,209 shares of Common Stock and assuming the
full exercise of all outstanding warrants issued by the NASD to purchase
outstanding shares of Common Stock owned by it, the NASD owns approximately
40.6% of the Issuer.

          (b) Except as set forth in this Section 3.05, there are no
outstanding (i) shares of capital stock or voting securities of the Issuer,
(ii) securities of the Issuer convertible into or exchangeable for shares
of capital stock or voting securities of the Issuer or (iii) options or
other rights to acquire from the Issuer, or any other obligation of the
Issuer to issue, any capital stock, voting securities or securities
convertible into or exchangeable for capital stock or voting securities of
the Issuer (the items in clauses 3.05(b)(i), 3.05(b)(ii) and 3.05(b)(iii)
being referred to collectively as the "Issuer Securities"). Except for the

corporation duly incorporated, validly existing and in good standing under

all material governmental licenses, authorizations, permits, consents and
approvals required to carry on its business as now conducted. Each
Subsidiary of the Issuer is duly qualified to do business as a foreign
corporation and is in good standing in each jurisdiction where such
qualification is necessary, except for those jurisdictions where failure to
be so qualified would not, individually or in the aggregate, have a
Material Adverse Effect. All Subsidiaries of the Issuer as of the date
hereof and their respective jurisdictions of incorporation are identified
on Schedule 3.06.

         (b) Except as disclosed on Schedule 3.06, all of the outstanding
capital stock or other voting securities of each Subsidiary of the Issuer
(except for any directors' qualifying shares) is owned by the Issuer,
directly or indirectly, free and clear of any Lien and free of any other
limitation or restriction (including any restriction on the right to vote,
sell or otherwise dispose of such capital stock or other voting
securities). There are no outstanding (i) securities of the Issuer or any
Subsidiary of the Issuer convertible into or exchangeable for shares of
capital stock or voting securities of any Subsidiary of the Issuer or (ii)
options or other rights to acquire from the Issuer or any Subsidiary of the
Issuer, or other obligation of the Issuer or any Subsidiary of the Issuer
to issue, any capital stock, voting securities or securities convertible
into or exchangeable for capital stock or voting securities of any
Subsidiary of the Issuer (the items in clauses 3.06(b)(i) and 3.06(b)(ii)
being referred to collectively as the "Subsidiary Securities"). There are
no outstanding obligations of the Issuer or any Subsidiary of the Issuer to
repurchase, redeem or otherwise acquire any outstanding Subsidiary
Securities.

         (c) Except as set forth on Schedule 3.06, the Issuer has no
ownership interest or other investment convertible into or exchangeable for
an ownership interest in any Person.

         SECTION 3.07. Financial Statements. The audited consolidated
balance sheets as of December 31, 1998 and 1999 and the related audited
consolidated statements of income and cash flows for each of the years
ended December 31, 1998 and 1999 and the unaudited consolidated balance
sheet for the nine months ended September 30, 2000 and the related
unaudited consolidated statements of income and cash flows for the nine

of law, all confidential documents and information concerning the Issuer or
any of its Subsidiaries furnished to the Purchasers or their Affiliates in

be shown to have been (i) previously known on a nonconfidential basis by
the Purchasers, (ii) in the public domain through no fault of the
Purchasers or (iii) acquired by the Purchasers from sources other than the

accountants, counsel, consultants, advisors and agents in connection with
the transactions contemplated by this Agreement so long as such Persons are
informed by the Purchasers of the confidential nature of such information
and are directed by the Purchasers to treat such information
confidentially. The Purchasers will be responsible for the breach by any
such persons of this Section 6.01. If this Agreement is terminated, the
Purchasers and its Affiliates will, and will use their reasonable best
efforts to cause their respective officers, directors, employees,
accountants, counsel, consultants, advisors and agents to, destroy or
deliver to the Issuer, upon request, all documents and other materials, and
all copies thereof, obtained by the Purchasers or its Affiliates or on
their behalf from the Issuer or any of its Subsidiaries in connection with
this Agreement that are subject to such confidence.

required to be obtained from parties to any material contracts, in
connection with the consummation of the transactions contemplated by this
Agreement and (ii) in taking such actions or making any such filings,
furnishing information required in connection therewith and seeking timely
to obtain any such actions, consents, approvals or waivers.

         SECTION 9.02. No Waivers; Amendments. (a) No failure or delay on
the part of any party in exercising any right, power or privilege hereunder

         (b) Any provision of this Agreement may be amended or waived if,
but only if, such amendment or waiver is in writing and is signed by all
parties hereto.

         SECTION 9.03. Survival of Provisions. The representations and
warranties contained in this Agreement shall survive and remain in full
force and effect in accordance with their terms until the date which is
three months after the date on which the Issuer delivers to the Purchasers

fiscal year 2001; provided that the representations and warranties
contained in Section 3.02 and Article 4 shall survive indefinitely.

         SECTION 9.04. Indemnification. (a) The Issuer hereby agrees to
indemnify and hold harmless each Purchaser, any Affiliate of any Purchaser,
any Person controlling any Purchaser or such Affiliate and their respective
directors, officers, agents and employees from and against any losses,
claims, damages, expenses and liabilities (including, without limitation,
reasonable expenses of investigation and reasonable attorneys' fees and
expenses in connection with any action, suit or proceeding) ("Damages") to
which such person may become subject as the result of any breach of
representation, warranty or covenant made or to be performed on the part of
the Issuer under this Agreement, the Securityholders Agreement, or the
Securities or any third-party action, claim or proceeding directly
resulting from the matters or transactions which are the subject of or
contemplated by this Agreement or the Securityholders Agreement or the
Securities (or any use made or proposed to be made by the Issuer of the
proceeds from the sale of the Securities) and will reimburse any such
person for all reasonable expenses (including reasonable counsel fees and
expenses) as they are incurred by any such person in connection with any
such breach of representation, warranty or covenant or investigating,
preparing or defending any such action or proceeding, pending or
threatened, whether or not such person is a party thereto; provided that
with respect to indemnification or reimbursement by the Issuer pursuant to
this Section, (i) the Issuer shall not be liable unless the aggregate
amount of Damages exceeds $1,000,000, and the Issuer shall only be liable
for Damages in excess of such amount, and (ii) the Issuer's maximum
liability shall not exceed the purchase price of the Securities.

         (b) Each Purchaser hereby agrees to indemnify, defend and hold
harmless the Issuer and its Affiliates, any Person controlling the Issuer
or its Affiliates and their respective directors, officers, agent and
employees from and against any Damages to which such person may become
subject as a result of any breach of any representation, warranty or
covenant made or to be performed on the part of such Purchaser under this
Agreement or the Securityholders Agreement and will reimburse any such
person for all reasonable expenses (including reasonable counsel fees and
expenses) as they are incurred by any such person in connection with any
such breach of representation, warranty or covenant or investigating,
preparing or defending any such action or proceeding, pending or
threatened, whether or not such person is a party thereto; provided that
with respect to indemnification or reimbursement by the Purchasers pursuant
to this Section, (i) the Purchasers shall not be liable unless the
aggregate amount of Damages exceeds $1,000,000, and the Purchasers shall
only be liable for Damages in excess of such amount, and (ii) the
Purchaser's maximum liability shall not exceed the purchase price of the
Securities.

         (c) Promptly after receipt by any person (the "Indemnified
Person") of notice of any demand, claim or circumstances which would or
might give rise to a claim or the commencement of any action, proceeding or
investigation in respect of which indemnity may be sought pursuant to
Section 9.04(a) or (b), such Indemnified Person shall give notice thereof
to the person against whom such indemnity may be sought (the "Indemnifying
Person"). Notwithstanding the foregoing, the failure so to give prompt
notice to such person will not relieve such Indemnifying Person from
liability, except to the extent such failure or delay materially prejudices
such Indemnifying Person. The Indemnifying Person shall be entitled to
participate in any such action and to assume the defense thereof, at the
Indemnifying Person's expense and with counsel reasonably satisfactory to
the Indemnified Person. After notice from the Indemnifying Person to such
Indemnified Person of its election so to assume the defense thereof, the
Indemnified Person shall have the right to participate in such action and
to retain its own counsel, but the Indemnifying Person shall not be liable
to such Indemnified Person hereunder for any legal expenses of other
counsel or any other expenses, in each case, subsequently incurred by such
Indemnified Person, in connection with the defense thereof other than
reasonable costs of investigation, unless (i) the Indemnifying Person has
agreed to pay such fees and expenses, (ii) the Indemnifying Person shall
have failed to employ counsel reasonably satisfactory to the Indemnified
Person in a timely manner or (iii) the Indemnified Person shall have been
advised by outside counsel that representation of the Indemnified Person by
counsel provided by the Indemnifying Person pursuant to the foregoing would
be inappropriate due to an actual or potential conflicting interest between
the Indemnifying Person and the Indemnified Person, including situations in
which there are one or more legal defenses available to the Indemnified
Person that are different from or additional to those available to the
Indemnifying Person; provided however, that the Indemnifying Person shall
not, in connection with any one such action or proceeding or separate but
substantially similar actions or proceedings arising out of the same
general allegations, be liable for the fees and expenses of more than one
firm of attorneys at one time for the Indemnified Person.

         (d) Except in the case of fraud, or with respect to matters for
which the remedy of specific performance or injunctive relief or other
equitable remedies are appropriate or available, the respective rights to
indemnification as provided for in this Section 9.04, shall constitute each
party's sole remedy and no party shall have any other liability or damages
to the other party; provided, however, that nothing contained herein shall
prevent the Indemnified Person from pursuing remedies as may be available
to such party under applicable law in the event of an Indemnifying Person's
failure to comply with its indemnification obligations hereunder.

         SECTION 9.05. Expenses; Documentary Taxes. The Issuer shall
reimburse the Purchasers at Closing for all of their respective documented
out-of-pocket reasonable expenses, including reasonable fees and
disbursements of counsel, accountants and other consultants, in connection
with their investigation of the Issuer, their evaluation of the
transactions contemplated hereby, and the preparation of this Agreement,
the Securityholders Agreement and the Securities and any amendments
thereto, up to a maximum of $1,000,000. The Issuer shall pay any and all
stamp, transfer and other similar taxes payable or determined to be payable
in connection with the execution and delivery of this Agreement or the
Securityholders Agreement, or the issuance of the Securities.

         SECTION 9.06. Termination. (a) This Agreement may be terminated at
any time prior to the Closing:

         (i) by mutual written agreement of the Issuer and the Purchasers;

         (ii) by the Issuer or the Purchasers if the Closing shall not have
         been consummated on or before May 31, 2001;

         (iii) by the Issuer or the Purchasers if there shall be any law or
         regulation that makes consummation of the transactions
         contemplated hereby illegal or otherwise prohibited or if
         consummation of the transactions contemplated hereby would violate
         any nonappealable final order, decree or judgment of any court or
         governmental body having competent jurisdiction;

         (iv) by the Issuer or the Purchasers, if there has been a material
         misrepresentation, breach of warranty or breach of covenant or
         other obligation hereunder on the part of the Purchasers (in the
         case of termination by the Issuer) or the Issuer (in the case of
         termination by the Purchasers); or if any condition to such
         party's obligations hereunder becomes incapable of fulfillment
         through no fault of such party; or

         (v) by the Issuer or the Purchasers, if the Purchase and Sale
         Agreement is terminated for any reason.

         The party desiring to terminate this Agreement pursuant to clauses
9.06(a)(ii), (iii), (iv) or (v) shall give notice of such termination to
the other parties.

         (b) If this Agreement is terminated as permitted by Section
9.06(a), such termination shall be without liability of either party (or
any stockholder, director, officer, employee, agent, consultant or
representative of such party) to the other parties to this Agreement;
provided that if such termination shall result from the willful (i) failure
of any party to fulfill a condition to the performance of the obligations
of the other parties, (ii) failure to perform a covenant of this Agreement
or (iii) breach by any party hereto of any representation or warranty or
agreement contained herein, such party shall be liable for damages incurred
or suffered by the other party as a result of such failure or breach.

         SECTION 9.07. Successors and Assigns. The Issuer may not assign
any of its rights and obligations hereunder without the prior written
consent of the Purchasers. No Purchaser may assign its rights and
obligations hereunder without the consent of the Issuer, except to any
Affiliate of the Purchaser. This Agreement shall be binding upon the Issuer
and the Purchasers and their respective successors and assigns. Neither
this Agreement nor any provision hereof shall be construed so as to confer
any right or benefit upon any Person other than parties to this Agreement
and their respective successors and permitted assigns.

         SECTION 9.08.  Headings.  The headings in this Agreement are for
convenience of reference only and shall not control or affect the meaning or
construction of any provisions hereof.

         SECTION 9.09. Severability. The invalidity or unenforceability of
any provisions of this Agreement in any jurisdiction shall not affect the
validity, legality or enforceability of the remainder of this Agreement in
such jurisdiction or the validity, legality or enforceability of this
Agreement, including any such provision, in any other jurisdiction, it
being intended that all rights and obligations of the parties hereunder
shall be enforceable to the fullest extent permitted by law.

         SECTION 9.10. Specific Performance. The parties hereto agree that
if any of the provisions of this Agreement were not performed in accordance
with their specific terms or were otherwise breached, irreparable damage
would occur, no adequate remedy at law would exist and damages would be
difficult to determine, and that the parties shall be entitled to specific
performance of the terms hereof and immediate injunctive relief, without
the necessity of proving the inadequacy of money damages as a remedy, in
addition to any other remedy at law or equity.

         SECTION 9.11. New York Law. This Agreement shall be governed and
construed in accordance with the laws of the State of New York without
giving effect to conflicts of laws principles thereof.

         SECTION 9.12. Counterparts; Effectiveness. This Agreement may be
executed in any number of counterparts each of which shall be an original
with the same effect as if the signatures thereto and hereto were upon the
same instrument.

         SECTION 9.13. Entire Agreement. This Agreement constitutes the
entire agreement and understanding among the parties hereto and supersedes

or regulation of any administrative or governmental body) shall have
occurred and be continuing:

         (a) default in the payment of any interest upon any of the Notes
as and when the same shall become due and payable, and continuance of such
default for a period of 30 days; or

         (b) default in the payment of all or any part of the principal of
any of the Notes as and when the same shall become due and payable; or

         (c) failure on the part of the Issuer duly to observe or perform
any other of the covenants or agreements on the part of the Issuer
contained in the Notes (other than those covered by clauses (a) through (b)
above) for a period of 60 days after the date on which written notice
specifying such failure, stating that such notice is a "Notice of Default"
hereunder and demanding that the Issuer remedy the same, shall have been
given by registered or certified mail, return receipt requested, to the
Issuer; or

         (d) any acceleration of the maturity of any Debt of the Issuer or
any of its subsidiaries having a principal amount greater than $50,000,000;
or

         (e) a final and non-appealable judgment or order (not covered by
insurance) for the payment of money shall be rendered against the Issuer or
any of its subsidiaries in excess of $50,000,000 in the aggregate for all
such judgments or orders (treating any deductibles, self insurance or
retention as not so covered), and such judgment or order shall continue
unsatisfied for a period of 60 days; or

         (f) a court having jurisdiction shall enter a decree or order for
relief in respect of the Issuer in an involuntary case under applicable
bankruptcy, insolvency or other similar law now or hereafter in effect, or
appointing a receiver, liquidator, assignee, custodian, trustee,
sequestrator (or similar official) of the Issuer or for any substantial
part of the property of the Issuer or ordering the winding up or
liquidation of the affairs of the Issuer, and such decree or order shall
remain unstayed and in effect for a period of 60 consecutive days; or

         (g) the Issuer shall commence a voluntary case under any
applicable bankruptcy, insolvency or other similar law now or hereafter in
effect, or consent to the entry of an order for relief in an involuntary
case under any such law, or consent to the appointment or taking possession
by a receiver, liquidator, assignee, custodian, trustee, sequestrator (or
similar official) of the Issuer or for any substantial part of the property
of the Issuer, or the Issuer shall make any general assignment for the
benefit of creditors.

         then, and in each and every such case (other than an Event of
Default specified in Sections 4.1(f) or 4.1(g) hereof), the Holders of at
least a majority in aggregate principal amount of the Notes then
outstanding, by notice in writing to the Issuer (the "Acceleration
Notice"), may declare the entire principal amount of the Notes and the
interest accrued thereon to be due and payable immediately, and upon any
such declaration the same shall become immediately due and payable;
provided that if an Event of Default specified in Section 4.1(f) or 4.1(g)
occurs, the principal amount of and accrued interest on the Notes shall
become and be immediately due and payable without any declaration or other
act on the part of any Holder.

         Section 4.2. Powers and Remedies Cumulative; Delay or Omission Not
Waiver of Default. No right or remedy herein conferred upon or reserved to
any Holder is intended to be exclusive of any other right or remedy, and
every right and remedy shall, to the extent permitted by law, be cumulative
and in addition to every other right and remedy given hereunder or now or
hereafter existing at law or in equity or otherwise. The assertion or
employment of any right or remedy hereunder, or otherwise, shall not
prevent the concurrent assertion or employment of any other appropriate
right or remedy.

         No delay or omission of any Holder to exercise any right or power
accruing upon any Event of Default occurring and continuing as aforesaid
shall impair any such right or power or shall be construed to be a waiver
of any such Event of Default or an acquiescence therein; and every power
and remedy given by the Notes or by law may be exercised from time to time,
and as often as shall be deemed expedient, by any Holder.

         Section 4.3. Waiver of Past Defaults. The Holders of the Notes may
waive, in accordance with Section 8.1, any past Default or Event of Default
hereunder and its consequences. In the case of any such waiver, the Issuer
and the Holders of the Notes shall be restored to their former positions
and rights hereunder, respectively; but no such waiver shall extend to any
subsequent or other Default or impair any right consequent thereon.

         Upon any such waiver, such Default shall cease to exist and be
deemed to have been cured and not to have occurred, and any Event of
Default arising therefrom shall be deemed to have been cured, and not to
have occurred for every purpose of the Notes; but no such waiver shall
extend to any subsequent or other Default or Event of Default or impair any
right consequent thereon.

         Section 5.1 Conversion Rights. (a) Subject to the provisions of
this Section 5, the Holders of the Notes shall have the right, at any time
and from time to time, at such Holder's option, to convert the Principal
Amount of this Note, in whole or part (the "Conversion Amount"), into fully
paid and non-assessable shares of Common Stock at the then effective
Conversion Ratio (as such term is defined below). The number of shares of
Common Stock deliverable upon conversion of each $1,000 Conversion Amount
of the Notes, adjusted as hereinafter provided, is referred to herein as
the "Conversion Ratio". The Conversion Ratio, as of the date of issue of
the Notes is 50.0000, subject to adjustment from time to time pursuant to
Section 5.1(f) hereof.

       (b)(i) In order to exercise the conversion privilege, the Holder of
the Note to be converted shall surrender the Note, with a written notice to
the Issuer that such Holder elects to exercise its conversion privilege,
and stating the Conversion Amount of Notes which the Holder seeks to
convert. The date of receipt of the Note or Notes by the Issuer shall be
the conversion date (the "Conversion Date").

         (ii) As promptly as practicable (but no later than two days) after
         the Conversion Date, the Issuer shall issue and shall deliver to
         such Holder, or on the Holder's written order to the Holder's
         permitted transferee in accordance with the terms of the
         Securityholders Agreement, a certificate or certificates for the
         whole number of shares of Common Stock issuable upon the
         conversion of such Note or Notes in accordance with the provisions
         of this Section 5.1.

         (iii) In the case where only part of a Note is converted, the
         Issuer shall execute and deliver (at its own expense) a new Note
         of any authorized denomination as requested by a Holder in an
         aggregate principal amount equal to and in exchange for the
         unconverted portion of the Principal Amount of the Note so
         surrendered.

         (iv) The Issuer shall made a cash payment equal to all accrued and
         unpaid interest on the Principal Amount so surrendered for
         conversion (other than interest payments payable to a holder of
         record on a prior Interest Payment Date) to the Conversion Date.

         (v) Each conversion shall be deemed to have been effected
         immediately prior to the close of business on the date on which
         the Notes to be converted shall have been surrendered, and the
         person in whose name or names any certificate or certificates for
         shares of Common Stock shall be issuable upon such conversion
         shall be deemed to have become the holder of record of the shares
         of Common Stock represented thereby on such date and such
         conversion shall be into a number of shares of Common Stock
         resulting from applying the Conversion Ratio in effect at such
         time on such date. All shares of Common Stock delivered upon
         conversion of the Notes will upon delivery be duly and validly
         issued and fully paid and non-assessable, free of all Liens and
         charges and not subject to any preemptive rights. Upon the
         surrender of any Notes for conversion, such Notes or part thereof
         so converted shall no longer be deemed to be outstanding and all
         rights of a Holder with respect to such Notes or part thereof so
         converted including the rights, if any, to receive interest,
         notices and consent rights shall immediately terminate on the
         Conversion Date except the right to receive the Common Stock and
         other amounts payable pursuant to this Section 5.1. Any Notes or
         part thereof so converted shall be retired and cancelled.

         (c) (i) The Issuer covenants that it will at all times during
which the Notes shall be outstanding reserve and keep available, free from
preemptive rights, such number of its authorized but unissued shares of
Common Stock as shall from time to time be required for the purpose of
effecting conversions of outstanding Notes. Before taking any action which
would cause an adjustment increasing the Conversion Ratio such that the
amount resulting from dividing $1,000 by the Conversion Ratio in effect at
such time on such date would be below the then par value of the shares of
Common Stock issuable upon conversion of the Notes, the Issuer will take
any corporate action which may, in the opinion of counsel, be necessary in
order that the Issuer may validly and legally issue fully paid and
nonassessible shares of Common Stock at such adjusted Conversion Ratio.

         (ii) Prior to the delivery of any securities which the Issuer
         shall be obligated to deliver upon conversion of the Notes, the
         Issuer shall comply with all applicable federal and state laws and
         regulations which require action to be taken by the Issuer.

         (d) The Issuer will pay any and all documentary stamp or similar
issue or transfer taxes payable in respect of the issue or delivery of
shares of Common Stock on conversion of the Notes pursuant hereto; provided
that the Issuer shall not be required to pay any tax which may be payable
in respect of any transfer involved in the issue or delivery of shares of
Common Stock in a name other than that of the holder of the Notes to be
converted and no such issue or delivery shall be made unless and until the
person requesting such issue or delivery has paid to the Issuer the amount
of any such tax or has established, to the satisfaction of the Issuer, that
such tax has been paid.

         (e) If the conversion is in connection with an underwritten
offering of securities registered pursuant to the Securities Act of 1933,
as amended, the conversion may, at the option of any Holder tendering Notes
for conversion, be conditioned upon the closing with the underwriter of the
sale of securities pursuant to such offering, in which event the Holders
entitled to receive the Common Stock issuable upon such conversion of the
Notes shall not be deemed to have converted such Notes until immediately
prior to the closing of the sale of securities in such offering.

         (f) (i) In case the Issuer shall at any time after the date of
issue of the Notes (A) declare a dividend or make a distribution on Common
Stock payable in Common Stock, (B) subdivide or split the outstanding
Common Stock, (C) combine or reclassify the outstanding Common Stock into a
smaller number of shares, (D) issue any shares of its Capital Stock in a
reclassification of Common Stock (including any such reclassification in
connection with a consolidation or merger in which the Issuer is the
continuing corporation), or (E) consolidate with, or merge with or into,
any other Person, the Conversion Ratio in effect at the time of the record
date for any such dividend or distribution or of the effective date of any
such subdivision, split, combination, consolidation, merger or
reclassification shall be proportionately adjusted so that the conversion
of the Note after such time shall entitle the Holder to receive the
aggregate number of shares of Common Stock or other securities of the
Issuer (or shares of any security into which such shares of Common Stock
have been combined, consolidated, merged, converted or reclassified
pursuant to clause (C), (D) or (E) above) which, if this Note had been
converted immediately prior to such time, such Holder would have owned upon
such conversion and been entitled to receive by virtue of such dividend,
distribution, subdivision, split, combination, consolidation, merger or
reclassification, assuming for purposes of this subsection (f) that such
Holder (x) is not a Person with which the Issuer consolidated or into which
the Issuer merged or which merged into the Issuer or to which such
recapitalization, sale or transfer was made, as the case may be
("constituent person") and (y) failed to exercise any rights of election as
to the kind or amount of securities, cash and other property receivable
upon such reclassification, change, consolidation, merger,
recapitalization, sale or transfer (provided, that if the kind or amount of
securities, cash and other property receivable upon such reclassification,
change, consolidation, merger, recapitalization, sale or transfer is not
the same for each share of Common Stock of the Issuer held immediately
prior to such reclassification, change, consolidation, merger,
recapitalization, sale or transfer by other than a constituent person and
in respect of which such rights of election shall not have been exercised
("non-electing share"), then for the purpose of this Section 5.1(f) the
kind and amount of securities, cash and other property receivable upon such
reclassification, change, consolidation, merger, recapitalization, sale or
transfer by each non-electing share shall be deemed to be the kind and
amount so receivable per share by a plurality of the non-electing shares).
Such adjustment shall be made successively whenever any event listed above
shall occur.

         (ii) For purposes of any computation under this Section 5.1(f),
         the number of shares of Common Stock outstanding at any given time
         shall not include shares owned or held by or for the account of
         the Issuer. All calculations under this Section 5.1(f) shall be
         made to the nearest four decimal points.

         (iii) In the event that, at any time as a result of the provisions
         of this Section 5.1(f), the holder of this Note upon subsequent
         conversion shall become entitled to receive any shares of Capital
         Stock of the Issuer other than Common Stock, the number of such
         other shares so receivable upon conversion of this Note shall
         thereafter be subject to adjustment from time to time in a manner
         and on terms as nearly equivalent as practicable to the provisions
         contained herein.

         (g) No fractional shares of Common Stock shall be issued upon
conversion of the Notes. In lieu of fractional shares, the Issuer shall pay
cash equal to such fraction multiplied by the Closing Price for shares of
Common Stock on the trading day immediately preceding the related
Conversion Date. "Closing Price" means (1) if the shares of such class of
Common Stock then are listed and traded on the National Market of the
National Association of Securities Dealers, Inc. Automated Quotation System
("NASDAQ"), the last reported sale price on such day; (2) if the shares of
such class of Common Stock then are not traded on the NASDAQ National
Market, the average of the highest reported bid and lowest reported asked
price on such day as reported by NASDAQ; (3) if the shares of such class of
Common Stock then are not listed and traded on the NASDAQ, the closing
price on such day as reported by the principal national securities exchange
on which the shares are listed and traded; or (4) if the shares of such
class of Common Stock are not then listed or traded on NASDAQ or a national
securities exchange, the fair market value as determined in good faith by
the Issuer's Board of Directors.

         (h) Upon the occurrence of each adjustment or readjustment of the
Conversion Ratio pursuant to this Section 5.1, the Issuer at its expense
shall promptly compute such adjustment or readjustment in accordance with
the terms hereof and furnish to each Holder of Notes outstanding a
certificate setting forth such adjustment or readjustment and showing in
detail the facts upon which such adjustment or readjustment is based and
shall file a copy of such certificate with its corporate records. The
Issuer shall, upon the reasonable written request of any Holder of Notes,
furnish or cause to be furnished to such Holders a similar certificate
setting forth (i) such adjustments and readjustments, (ii) the Conversion
Ratio then in effect, and (iii) the number of shares of Common Stock and
the amount, if any, of other property which then would be received upon the
conversion of the Notes. Despite such adjustment or readjustment, the form
of each or all Notes, if the same shall reflect the initial or any
subsequent Conversion Ratio, need not be changed in order for the
adjustments or readjustments to be valid in accordance with the provisions
of this Note, which shall control.

         (i) The Issuer will not, by amendment of its certificate of
incorporation or through any reorganization, transfer of assets,
consolidation, merger, dissolution, issue of sale of securities or any
other voluntary action, avoid or seek to avoid the observance or
performance of any of the terms to be observed or performed hereunder by
the Issuer, but will at all times in good faith assist in the carrying out
of all the provisions of this Section 5.1 and in the taking of all such
action as may be necessary or appropriate in order to protect the
conversion rights of the Holders of the Notes against impairment to the
extent required hereunder. Nothing in this Section 5.1 shall affect the
continued accrual of interest on the outstanding Notes in accordance with
the terms of this Note.

         (j) Notwithstanding any other provision of this Section 5.1, prior
to the Exchange Registration Date (as defined below), the Holders of the
Notes shall not have the right to convert the Principal Amount of this Note
plus accrued and unpaid interest thereon into shares of Common Stock to the
extent, but only to the extent, such conversion would result in The
National Association of Securities Dealers holding less than 50% of the
combined voting power in the Issuer. "Exchange Registration Date" means the
date upon which the Issuer becomes registered to operate as a national
securities exchange by the Securities and Exchange Commission.

         Section 6.1. Voting Rights. (a) The Holders of this Note shall be
entitled to such voting rights as may be provided in the certificate of
incorporation of the Issuer, in this Section 6.1, and as otherwise may be
provided by law.

          (b) Without the written consent of the Holders of a majority in
Principal Amount of the Notes or the vote of Holders of a majority in
Principal Amount of the Notes at a meeting of the Holders of the Notes
called for such purpose, the Issuer will not amend, alter or repeal any
provision of the Certificate of Incorporation (by merger or otherwise) so
as to adversely affect the preferences, rights or powers of the Holders of
the Notes.

         Section 7.  Subordination.

         Section 7.1. Notes Subordinated to Senior Debt. The Issuer
covenants and agrees and each Holder, by his acceptance hereof likewise
covenants and agrees, that all Notes shall be issued subject to the
provisions of Section 7 of this Note; and each person holding any Note,
whether upon original issue or upon transfer, assignment or exchange
thereof accepts and agrees that the payment of the principal amount of and
interest on the Notes by the Issuer shall, to the extent and in the manner
herein set forth, be subordinated and junior in right of payment, to the
prior payment in full of Senior Debt.

         Section 7.2. No Payment on Notes in Certain Circumstances. (a) If
any default in the payment of any principal of or interest on any Senior
Debt when due and payable, whether at maturity, upon any redemption, by
declaration or otherwise, occurs and is continuing, no payment shall be
made by the Issuer with respect to the principal of or interest on the
Notes or to acquire any of the Notes for cash or property other than
conversion of the Notes into Common Stock in accordance with Section 5.1
hereof.

         (b) If any event of default (other than a default in payment of
the principal of or interest on any Senior Debt) occurs and is continuing
(or if such an event of default would occur upon any payment with respect
to the Notes) with respect to any Senior Debt, as such event of default is
defined in such Senior Debt, permitting the holders thereof to accelerate
the maturity thereof and if the holder or holders or a representative of
such holder or holders gives written notice of the event of default to the
Issuer (a "Default Notice"), then, unless and until such event of default
has been cured or waived or has ceased to exist, the Issuer shall not be
obligated to, and shall not, (x) make any payment of or with respect to the
principal of or interest on the Notes or (y) acquire any of the Notes for
cash or property or otherwise other than conversion of the Notes into
Common Stock in accordance with Section 5.1 hereof. After the event of
default in such Default Notice has been cured or waived or ceases to exist,
the Issuer shall, subject to Section 7.2(a), promptly pay to the Holders of
the Notes all sums which the Issuer would have been obligated to pay from
the date of the Default Notice but for this Section 7.2(b).

         (c) Notwithstanding the foregoing, in the event that any payment
in cash shall be received by any Holder when such payment is prohibited by
Section 7.2(a) or 7.2(b), such payment shall be held in trust for the
benefit of, and shall be paid over or delivered to, the holders of Senior
Debt or their respective representatives, or to the trustee or trustees
under any indenture pursuant to which any of such Senior Debt may have been
issued, as their respective interests may appear, but only to the extent of
the amounts then due and owing on the Senior Debt, if any.

         Section 7.3 Payment Over of Proceeds Upon Dissolution, Etc. (a)
Upon any payment or distribution of assets of the Issuer of any kind or
character, whether in cash, property or securities, to creditors upon any
dissolution or winding-up or total or partial liquidation or reorganization
of the Issuer, whether voluntary or involuntary or in bankruptcy,
insolvency, receivership or other proceedings, all amounts due or to become
due upon all Senior Debt shall first be paid in full, or such payment duly
provided for, before any payment is made on account of the principal of or
interest on the Notes, or any acquisition of the Notes for cash or property
is made, other than conversion of the Notes into Common Stock in accordance
with Section 5.1 hereof. Upon any such dissolution, winding-up, liquidation
or reorganization, any payment or distribution of assets of the Issuer of
any kind or character, whether in cash, property or securities, to which
the Holders of the Notes would be entitled, except for the provisions
hereof, other than conversion of the Notes into Common Stock in accordance
with Section 5.1 hereof, shall be paid by the Issuer or by any receiver,
trustee in bankruptcy, liquidating trustee, agent or other person making
such payment or distribution, or by the Holders of the Notes if received by
them, directly to the holders of Senior Debt (pro rata to such holders on
the basis of the respective amounts of Senior Debt held by such holders) or
their respective representatives, or to the trustee or trustees under any
indenture pursuant to which any of such Senior Debt may have been issued,
as their respective interests may appear, for application to the payment of
Senior Debt remaining unpaid until all such Senior Debt has been paid in
full after giving effect to any concurrent payment, distribution or
provision therefor to or for the holders of Senior Debt.

         (b) Notwithstanding the foregoing, in the event that any payment
or distribution of assets of the Issuer of any kind or character, whether
in cash, property or securities, other than conversion of the Notes into
Common Stock in accordance with Section 5.1 hereof, shall be received by
any Holder when such payment or distribution is prohibited by Section
7.3(a), such payment or distribution shall be held in trust for the benefit
of, and shall be paid over or delivered to, the holders of Senior Debt (pro
rata to such holders on the basis of the respective amount of Senior Debt
held by such holders) or their respective representatives, or to the
trustee or trustees under any indenture pursuant to which any of such
Senior Debt may have been issued, as their respective interests may appear,
for application to the payment of Senior Debt remaining unpaid until all
such Senior Debt has been paid in full, after giving effect to any
concurrent payment, distribution or provision therefor to or for the
holders of such Senior Debt.

          (c) For purposes of Section 7 of this Note, the words "cash,
property or securities" shall not be deemed to include (x) shares of stock
of the Issuer as reorganized or readjusted, (y) any payment or distribution
of securities of the Issuer or any other Issuer authorized by an order or
decree giving effect, and stating in such order or decree that effect is
given, to the subordination of the Notes to the Senior Debt, and made by a
court of competent jurisdiction in a reorganization proceeding under any
applicable bankruptcy, insolvency or other similar law, or (z) securities
of the Issuer or any other Issuer provided for by a plan of reorganization
or readjustment which are subordinated, to at least the same extent as the
Notes, to the payment of all Senior Debt then outstanding; provided that
(i) if a new Issuer results from such reorganization or readjustment, such
Issuer assumes the Senior Debt and (ii) the rights of the holders of the
Senior Debt are not, without the consent of such holders, altered by such
reorganization or readjustment. Notwithstanding anything to the contrary in
this Section 7, (i) a court referred to in clause (x) above may give
effect, and state that it is giving effect to the subordination of the
Notes in an order or decree which authorizes the payment in full of Senior
Debt in assets other than cash or cash equivalents and (ii) any assets
which the holders of the Notes are permitted to receive in accordance with
the provisions of this Section 7 shall not be subject to any claim by or on
behalf of the holders of Senior Debt.

         7.4. Subrogation. Subject to the payment in full of all Senior
Debt, the Holders of the Notes shall be subrogated to the rights of the
holders of Senior Debt to receive payments or distributions of cash,
property or securities of the Issuer applicable to the Senior Debt until
the principal amount of and interest on the Notes shall be paid in full;
and, for the purposes of such subrogation, (a) no payments or distributions
to the holders of the Senior Debt of any cash, property or securities to
which the Holders of the Notes would be entitled except for the provisions
of Section 7 of this Note, and no payment over pursuant to the provisions
of Section 7 of this Note to the holders of Senior Debt by the Holders of
the Notes shall, as between the Issuer, its creditors other than holders of
Senior Debt, and the Holders of the Notes, be deemed to be a payment by the
Issuer to or on account of the Senior Debt, and (b) no payment or
distributions of cash, property or securities to or for the benefit of the
holders of the Notes pursuant to the subrogation provision of Section 7,
which would otherwise have been paid to the holders of Senior Debt shall,
as between the Issuer, its creditors other than holders of Senior Debt, and
the Holders of the Notes, be deemed to be a payment by the Issuer to or for
the account of the Notes. It is understood that the provisions of this
Section are and are intended solely for the purpose of defining the
relative rights of the Holders of the Notes, on the one hand, and the
holders of the Senior Debt, on the other hand.

         If any payment or distribution to which the Holders of the Notes
would otherwise have been entitled but for the provisions of this Section
7, shall have been applied, pursuant to the provisions of this Section 7,
to the payment of all amounts payable under Senior Debt, then and in such
case, the Holders of the Notes shall be entitled to receive from the
holders of such Senior Debt any payments or distributions received by such
holders of Senior Debt in excess of the amount required to make payment in
full of such Senior Debt.

         Section 7.5. Obligations of Issuer Unconditional. Nothing
contained in Section 6.1 or elsewhere in the Notes is intended to or shall
impair, as between the Issuer and the Holders of the Notes, the obligation
of the Issuer, which is absolute and unconditional, to pay to the Holders
of the Notes the principal amount of and interest on the Notes as and when
the same shall become due and payable in accordance with their terms, or is
intended to or shall affect the relative rights of the Holders of the Notes
and creditors of the Issuer other than the holders of the Senior Debt, nor
shall anything herein or therein prevent any Holder from exercising all
remedies otherwise permitted by applicable law upon default under this
Note, subject to the rights, if any, under Section 7 of the holders of the
Senior Debt in respect of cash, property or securities of the Issuer
received upon the exercise of any such remedy.

         Without limiting the generality of the foregoing, nothing
contained in Section 7 will restrict the right of the Holders of the Notes
to take any action to declare the Notes to be due and payable prior to
their stated maturity pursuant to Section 4.1 or to pursue any rights or
remedies hereunder.

         Section 7.6. Reliance on Judicial Order or Certificate of
Liquidating Agent. Upon any payment or distribution of assets of the Issuer
referred to in Section 7, the Holders of the Notes shall be entitled to
rely upon any order or decree made by any court of competent jurisdiction
in which bankruptcy, dissolution, winding-up, liquidation or reorganization
proceedings are pending, or a certificate of the receiver, trustee in
bankruptcy, liquidating trustee, agent or other person making such payment
or distribution, delivered to the Holders of the Notes, for the purpose of
ascertaining the persons entitled to participate in such distribution, the
holders of the Senior Debt and other indebtedness of the Issuer, the amount
thereof or payable thereon, the amount or amounts paid or distributed
thereon and all other facts pertinent thereto or to Section 7 of this Note.

         Section 7.7. Subordination Rights Not Impaired by Acts or
Omissions of the Issuer or Holders of Senior Debt. No right of any present
or future holders of any Senior Debt to enforce subordination as provided
herein will at any time in any way be prejudiced or impaired by any act or
failure to act on the part of the Issuer or by any act or failure to act,
in good faith, by any such holder, or by any noncompliances by the Issuer
with the terms of this Note, regardless of any knowledge thereof which any
such holder may have or otherwise be charged with. The holders of Senior
Debt may extend, renew, modify or amend the terms of the Senior Debt or any
security therefor and release, sell or exchange such security and otherwise
deal freely with the Issuer, all without affecting the liabilities and
obligations of the Holders of the Notes.

         Section 7.8. Section 7 Not to Prevent Events of Default. The
failure to make a payment on account of principal of or interest on the
Notes by reason of any provision of Section 7 will not be construed as
preventing the occurrence of an Event of Default.

         Section 8.1. Modification of Notes. Any provision of this Note may
be amended or, subject to Section 4, waived with the written consent of the
Issuer and the Holders of at least a majority in aggregate principal amount
of the Notes then outstanding; provided that no such amendment or waiver
shall (a) extend the final maturity of any Note, or reduce the principal
amount thereof, or reduce the rate or extend the time of payment of
interest thereon, or reduce any amount payable on the conversion thereof,
or impair or affect the rights of any Holder to institute suit for the
payment thereof or adversely affect the ranking of the Notes with respect
to the outstanding Debt of the Issuer, in each such case, without the
consent of each Holder of each Note so affected, (b) reduce the aforesaid
percentage of Notes, the consent of the Holders of the Notes of which is
required for any such amendment or waiver, without the consent of the
Holders of all Notes then outstanding, or (c) modify the terms of the Notes
so as to affect adversely the rights of any holder of Senior Debt at the
time outstanding to the benefits of subordination hereunder without the
consent of such holder. The Issuer shall promptly notify all of the Holders
of the Notes after the making of any amendment or waiver pursuant to this
Section 8.1.

interest and principal on this Note, the Issuer shall be entitled to rely
on the name and address in the Register and notwithstanding anything to the
contrary contained in this Note, no Event of Default shall occur under

Register.

until the earlier of (i) the effective date of the registration statement
filed in connection with the Company's Initial Public Offering, or (ii)
June 28, 2002, without the prior written consent of the Company, no Holder

         (b) Following the expiration of the period set forth in Section
2.01(a):

          (i) without the prior written consent of the Company, no Holder
         shall Transfer any Equity Securities (other than in a registered

         securities exchange, alternative trading system ("ATS"),
         electronic communications network ("ECN"), the NASD, any
         Competitor, or any Affiliate of any of the foregoing; and

         (ii) with respect to any Transfer of Equity Securities by a Holder
         other than (A) a Transfer to an Affiliate or a Transfer in a
         registered public offering or in compliance with Rule 144, and (B)
         a Transfer in accordance with Section 2.01(b)(i), the Holder shall
         consult with the Company in good faith prior to such Transfer,
         taking into account the circumstances of such proposed Transfer.

          (c) Subject to compliance with all applicable securities laws and
this Agreement, each Holder may Transfer its Equity Securities, in whole or
in part, without restriction; provided that, the transferee (other than in
a Transfer pursuant to a registered public offering under the Securities
Act or in compliance with Rule 144) shall have executed and delivered to
each other party hereto an instrument confirming that such transferee
agrees to be bound by the terms of this Agreement applicable to the
transferor, whereupon such transferee shall become a Holder for purposes of
this Agreement.

         SECTION 2.02. Restrictive Legends. (a) Each certificate for Equity
Securities issued to any Holder or to a subsequent transferee shall (unless
otherwise permitted by the provisions of Section 2.02(b)) include a legend
in substantially the following form:

         THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
         1933, AS AMENDED, OR UNDER THE SECURITIES LAWS OF ANY STATE OR
         FOREIGN JURISDICTION AND MAY NOT BE OFFERED OR SOLD EXCEPT IN
         COMPLIANCE WITH APPLICABLE FEDERAL, STATE OR FOREIGN SECURITIES
         LAWS. THIS SECURITY IS ALSO SUBJECT TO ADDITIONAL RESTRICTIONS ON
         TRANSFER, AS SET FORTH IN THE SECURITYHOLDERS AGREEMENT, DATED AS
         OF _____________, 2001, A COPY OF WHICH MAY BE OBTAINED FROM THE
         NASDAQ STOCK MARKET, INC.

          (b) In connection with a proposed Transfer of any Equity
Securities permitted under Section 2.01, any Holder may, (i) upon providing
evidence reasonably satisfactory to the Company that such Equity Security
is not a "restricted security" (as defined in Rule 144) or (ii) after
expiration of the applicable holding period under Rule 144, exchange the
certificate representing such Equity Security for a new certificate that
does not bear the legend set forth in Section 2.02(a).

                                 ARTICLE 3

                            REGISTRATION RIGHTS

         SECTION 3.01. Demand Registration. (a) Request for Registration.
At any time beginning 180 days after the consummation of the Company's
Initial Public Offering, for so long as any Holder owns any Registrable
Securities, any Holder of Notes (a "Demand Registrant") may make a written
request (the "Registration Request") for registration under the Securities
Act of Registrable Securities having a value (based on the average closing
sale price per Common Share for 10 trading days preceding the Registration
Request) of not less than $50,000,000 (or, if less, all of the Registrable
Securities then held by the Holders) (a "Demand Registration"), unless
otherwise agreed by the Company and the Selling Holders. Notwithstanding
the foregoing, the Company shall not be required to file a registration
statement pursuant to a Registration Request within 90 days of the
effective date of any other registration statement filed by the Company
pursuant to the Securities Act, excluding registration statements filed on
Form S-4 or S-8 (or any substitute form that may be adopted by the
Commission). Any Registration Request will specify the number of
Registrable Securities proposed to be sold and the intended method of
disposition thereof. The Holders shall be entitled to request: (i) two
Demand Registrations on Form S-1 or any equivalent registration form;
provided, however, that if on or before July 1, 2002, the Company is
eligible to register securities on Form S-3, the Holders shall only be
entitled to request one Demand Registration on Form S-1 or any equivalent
registration form and (ii) unlimited Demand Registrations on Form S-3 or
any equivalent registration form (but no more than two in any twelve-month
period); and provided further, that if the NASD makes a demand to the
Company for the filing of a shelf registration statement pursuant to a
contractual right of registration, then the Company shall provide notice to
the Holders of such demand by the NASD and, if requested by the Holders (a
"Shelf Demand"), the Company shall file a shelf registration statement
pursuant to Section 415 of the Securities Act covering open market sales of
the Registrable Securities (the "Shelf Registration"), which Shelf
Registration shall be considered a Demand Registration for purposes of this
Agreement. The Holders shall be entitled to request only one Shelf Demand
pursuant to this Agreement.

         (b) Effective Registration. A registration requested pursuant to
this Section 3.01 shall not be deemed to be effected (i) if a registration
statement with respect thereto shall not have become effective (other than
due to any action or inaction by a Holder), (ii) if, after it has become
effective, such registration is interfered with for any reason (other than
due to any action or inaction by a Holder) by any stop order, injunction or
other order or requirement of the Commission or any other governmental
agency or any court, and the result of such interference is to prevent the
Holder from disposing of the Registrable Securities to be sold thereunder
in accordance with the intended methods of disposition or (iii) if the
conditions to closing specified in the purchase agreement or underwriting
agreement entered into in connection with any underwritten registration
shall not be satisfied or waived with the consent of the Company, the
Demand Registrant or the lead Underwriter, as applicable (other than due to
any action or inaction by a Holder).

         (c) Underwriting. The offering of Registrable Securities pursuant
to any Demand Registration shall be in the form of an underwritten
offering, a block trade or an open market transaction, as determined by the
Demand Registrant. The Demand Registrant shall, if applicable, select the
lead Underwriter and any additional investment bankers and managers in
connection with the offering from a list of nationally-recognized
investment banks reasonably agreed to between the Company and the Demand
Registrant.

         SECTION 3.02. Piggyback Registration. If the Company proposes to
file a registration statement under the Securities Act with respect to an
offering of its equity securities (i) for its own account (other than a
registration statement on Form S-4 or S-8 (or any substitute form that may
be adopted by the Commission)) or (ii) for the account of any holders of
its securities, then the Company shall give written notice of such proposed
filing to the Holders as soon as practicable (but in any event not less
than 10 days before the anticipated filing date), and such notice shall
offer the Holders the opportunity to register (a "Piggyback Registration")
any or all of the Registrable Securities. If any Holder wishes to register
securities of the same class or series as covered by the applicable
Piggyback Registration, such registration shall be on the same terms and
conditions as such Piggyback Registration. If, at any time after giving
written notice of its intention to register any equity securities and prior
to the effective date of a registration statement filed in connection with
such registration, the Company shall determine for any reason not to
register such equity securities, the Company may, at its election, give
written notice of such determination to each Holder and, thereupon, shall
not be obligated to register any Registrable Securities in connection
therewith.

         SECTION 3.03. Reduction of Offering. Notwithstanding any provision
to the contrary contained herein, if the lead Underwriter of an offering
described in Section 3.01 or 3.02 delivers a written opinion to the Company
that the offering price of the securities proposed to be included in such
offering would be materially and adversely affected by inclusion of all the
securities of each class requested to be included, the number of securities
to be registered by each holder shall be reduced to the extent recommended
by such lead Underwriter; provided, that (i) priority in a registration
initiated by a holder exercising a contractual right to demand such
registration shall be (a) first, the securities offered for the account of
such holder, (b) second, with respect to a registration for which a
registration statement is filed prior to the NASD Priority Termination Date
only, securities requested to be registered by the NASD pursuant to a
contractual right of registration, and (c) third, pro rata among any other
securities of the Company requested to be registered for its own account or
pursuant to a contractual right of registration, and (ii) priority in a
registration initiated by the Company pursuant to Section 3.02 shall be (a)
first, securities offered for the account of the Company, (b) second, with
respect to a registration for which a registration statement is filed prior
to the NASD Priority Termination Date only, securities requested to be
registered by the NASD pursuant to a contractual right of registration, and
(c) third, pro rata among other securities of the Company requested to be
registered pursuant to a contractual right of registration. For purposes of
this Section 3.03, "NASD Priority Termination Date" shall mean the earlier
of (i) the date which is six months after the date on which the Initial
Public Offering is consummated, and (ii) December 31, 2002.

         SECTION 3.04. Registration Procedures. Whenever the Company is
required to effect the registration of Registrable Securities pursuant to
Section 3.01, the Company will use its reasonable best efforts to effect
the registration and the sale of such Registrable Securities in accordance
with the intended method of disposition thereof as promptly as practicable,
and in connection with any such Registration Request:

         (a) The Company will as expeditiously as possible prepare and file
with the Commission a registration statement (including any necessary
amendments and supplements), subject to Section 3.01(a), 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, and the prospectus used in
connection therewith and use its reasonable best efforts to cause such
filed registration statement to become and remain effective, in the case of
registration that is not a Shelf Registration, for a period of 90 days or
such shorter period as necessary to complete the disposition of all
securities covered by such registration statement in accordance with the
intended method or methods of disposition thereof or, in the case of a
Shelf Registration, on a continuous basis until the earlier of (i) the date
on which all of the Registrable Securities covered by such Shelf
Registration are sold and (ii) the date on which the securities covered by
the Shelf Registration cease to be Registrable Securities; provided that if
the Company shall furnish to the Demand Registrant a certificate signed by
either its Chairman, President, or a Vice-President stating that in the
good faith judgment of its Board of Directors, the filing or effectiveness
of such registration statement would materially interfere with any proposed
acquisition, disposition, financing or other transaction involving the
Company or its subsidiaries, notwithstanding anything in this Section 3.04
to the contrary, the Company may postpone for up to 120 days in any
twelve-month period the filing or effectiveness of a registration statement
pursuant to a Holder's Registration Request; however, the Company will
during any such postponement take all action reasonably necessary or
desirable in order to be able to promptly file or request effectiveness of
the registration statement, as the case may be, upon termination of any
such postponement period.

         (b) The Company will, if requested, prior to filing a registration
statement or prospectus or any amendment or supplement thereto, furnish to
each Selling Holder and each 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 the Selling Holder
or such Underwriter may reasonably request in order to facilitate the sale
of the Registrable Securities. The Company will provide the Selling Holders
and the Underwriters reasonable time to review such documents and the
Company will consider in good faith incorporating any comments or other
information in such documents as the Selling Holder or the lead Underwriter
reasonably requests.

         (c) After the filing of the registration statement, the Company
will promptly notify the Selling Holder 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.

         (d) The Company will use its reasonable best efforts to (i)
register or qualify the Registrable Securities under such other securities
or blue sky laws of such jurisdictions in the United States as the Selling
Holder reasonably requests to keep such registration or qualification in
effect for so long as such registration statement remains in effect, and to
take any other action which may be reasonably necessary or advisable to
enable the Selling Holder to consummate the disposition in such
jurisdictions of the securities owned by the Selling Holder and (ii) cause
such Registrable Securities to be registered with or approved by such other
governmental agencies or authorities as may be necessary by virtue of the
business and operations of the Company, to enable the Selling Holder to
consummate the disposition of such Registrable Securities; provided, that
the Company will not be required to (i) qualify generally to do business in
any jurisdiction where it would not otherwise be required to qualify but
for this paragraph (d), (ii) subject itself to taxation in any such
jurisdiction other than taxation arising with respect to the registration
of securities or (iii) consent to general service of process in any such
jurisdiction.

         (e) At any time when a prospectus relating to the sale of
Registrable Securities is required to be delivered under the Securities
Act, the Company will immediately notify the Selling Holder of the
occurrence of an event requiring the preparation of a supplement or
amendment to such prospectus so that, as thereafter delivered to the
Holders 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 promptly make available to the Selling Holder and the
Underwriters any such supplement or amendment. The Selling Holder agrees
that, upon receipt of any notice from the Company of the happening of any
event of the kind described in the preceding sentence, the Selling Holder
will forthwith discontinue the offer and sale of Registrable Securities
pursuant to the registration statement covering such Registrable Securities
until receipt of the copies of such supplemented or amended prospectus and,
if so directed by the Company, the Selling Holder will deliver to the
Company all copies, other than permanent file copies then in the possession
of the Selling Holder, 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 as
provided in Section 3.04(a) by the number of days during the period from
and including the date of the giving of such notice to the date when the
Company shall make available to the Selling Holder such supplemented or
amended prospectus.

         (f) The Company will enter into customary agreements (including an
underwriting agreement in customary form) and take such other actions as
are reasonably required in order to expedite or facilitate the disposition
of such Registrable Securities, including without limitation furnishing the
Underwriters and Selling Holders with reasonable access to, and causing the
cooperation of, all personnel reasonably requested by the Underwriters and
the Selling Holders subject to appropriate confidentiality agreements to
assist in arranging such meetings with third parties as the Underwriters
and the Selling Holders may reasonably request, including without
limitation any "roadshow" or other similar marketing activity undertaken in
connection with the distribution of the Registrable Securities.

         (g) The Company will furnish to the Selling Holder and to each
Underwriter, if any, a signed counterpart, addressed to the Selling Holder
or such Underwriter, of (i) an opinion or opinions of counsel to the
Company and (ii) a comfort letter or comfort letters from the Company's
independent public accountants, each in customary form and covering such
matters as are customarily covered by opinions and comfort letters, as the
Selling Holder or the lead Underwriter therefor reasonably requests.

         (h) The Company will otherwise use its reasonable best 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.

         (i) The Company will provide and cause to be maintained a transfer
agent and registrar for all Registrable Securities covered by such
registration statement from and after a date not later than the effective
date of such registration statement.

         (j) The Company will use its reasonable best efforts (i) to cause
all Registrable Securities covered by such registration statement to be
listed on any national securities exchange (if such Registrable Securities
are not already listed), and on each other securities exchange, on which
similar securities issued by the Company are then listed, if the listing of
such Registrable Securities is then permitted under the rules of such
exchange; or (ii) to secure the 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, in each case if the Registrable Securities so
qualify, 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 or the Company, as applicable, if
requested by the Holder or by the lead Underwriter.

         (k) Subject to the provisions of Section 3.03, the Company may
include in such registration shares of Common Stock for its own account as
well as shares of Common Stock requested to be included in such
registration by any holder of Common Stock (other than the Holders)
pursuant to a contractual right of registration.

         SECTION 3.05. Registration Expenses. Registration Expenses (other
than underwriting discounts and commissions on the Holders' Registrable
Securities) incurred in connection with any registration made or requested
to be made pursuant to this Article 3 will be borne by the Company, whether
or not any such registration statement becomes effective.

         SECTION 3.06. Indemnification by the Company. To the extent
permitted by applicable law, the Company agrees to indemnify and hold
harmless each Selling Holder, its officers, directors and agents, and each
Person, if any, who controls each such Selling Holder within the meaning of
Section 15 of the Securities Act or Section 20 of the Exchange Act, from
and against any and all losses, claims, damages, liabilities and expenses
(collectively, "Damages") caused by any untrue statement or alleged untrue
statement of a material fact contained in any registration statement or
prospectus relating to the Registrable Securities (as amended or
supplemented if the Company shall have furnished any amendments or
supplements thereto) or any preliminary prospectus, or caused by any
omission or alleged omission to state therein a material fact required to
be stated therein or necessary to make the statements therein not
misleading, except insofar as such losses, claims, damages, liabilities or
expenses are caused by any such untrue statement or omission or alleged
untrue statement or omission based upon information furnished in writing to
the Company by or on behalf of any such Selling Holder expressly for use
therein. In addition, the indemnification provided in this Section 3.06
shall not inure to the benefit of any Selling Holder, if the Selling Holder
(or any underwriter or underwriters of the offering) failed to send or give
a copy of the final prospectus or any such amendment thereof or supplement
thereto, whichever is most recent, to the person asserting any such Damages
at or prior to the written confirmation of the sale of the securities by
such underwriter or underwriters to such person if there would have been no
liability if the final prospectus or any such amendment thereof or
supplement thereto had been delivered. The Company also agrees, to the
extent permitted by applicable law, 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 3.06.

         SECTION 3.07. Indemnification by Selling Holders. To the extent
permitted by applicable 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 either Section 15 of the Securities Act or Section 20
of the Exchange Act, to the same extent as the foregoing indemnity from the
Company to such Selling Holder, but only with reference to information
related to such Selling Holder furnished in writing by or on behalf of such
Selling Holder expressly for use in any registration statement or
prospectus relating to the Registrable Securities, or any amendment or
supplement thereto, or any preliminary prospectus. Each Selling Holder also
agrees, to the extent permitted by applicable law, 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 3.07.

         SECTION 3.08. Conduct of Indemnification Proceedings. In case any
proceeding (including any governmental investigation) shall be instituted
involving any Person in respect of which indemnity may be sought pursuant
to Section 3.06 or 3.07, such Person (the "Indemnified Party") shall
promptly notify the Person against whom such indemnity may be sought (the
"Indemnifying Party") in writing. Notwithstanding the foregoing, the
failure so to give prompt notice to such person will not relieve such
Indemnifying Party from liability, except to the extent such failure or
delay materially prejudices such Indemnifying Party. The Indemnifying Party
shall be entitled to participate in any such action and to assume the
defense thereof, at the Indemnifying Party's expense and with counsel
reasonably satisfactory to the Indemnified Party. After notice from the
Indemnifying Party to such Indemnified Party of its election so to assume
the defense thereof, the Indemnified Party shall have the right to
participate in such action and to retain its own counsel, but the
Indemnifying Party shall not be liable to such Indemnified Party hereunder
for any legal expenses of other counsel or any other expenses, in each
case, subsequently incurred by such Indemnified Party, in connection with
the defense thereof other than reasonable costs of investigation, unless
(i) the Indemnifying Party has agreed to pay such fees and expenses, (ii)
the Indemnifying Party shall have failed to employ counsel reasonably
satisfactory to the Indemnified Party in a timely manner or (iii) the
Indemnified Party shall have been advised by outside counsel that
representation of the Indemnified Party by counsel provided by the
Indemnifying Party pursuant to the foregoing would be inappropriate due to
an actual or potential conflicting interest between the Indemnifying Party
and the Indemnified Party, including situations in which there are one or
more legal defenses available to the Indemnified Party that are different
from or additional to those available to the Indemnifying Party; provided
however, that the Indemnifying Party shall not, in connection with any one
such action or proceeding or separate but substantially similar actions or
proceedings arising out of the same general allegations, be liable for the
fees and expenses of more than one firm of attorneys at one time for the
Indemnified Party. The Indemnifying Party shall not be liable for any
settlement of any proceeding effected without its consent, but if settled
with such consent, or if there be a final judgment for the plaintiff, the
Indemnifying Party shall indemnify and hold harmless such Indemnified
Parties from and against any loss or liability (to the extent stated above)
by reason of such settlement or judgment. No Indemnifying Party shall,
without the prior written consent of the Indemnified Party, effect any
settlement of any pending or threatened proceeding in respect of which any
Indemnified Party is or could have been a party and indemnity could have
been sought hereunder by such Indemnified Party, unless such settlement (x)
includes an unconditional release of such Indemnified Party from all
liability arising out of such proceeding and (y) provides that such
Indemnified Party does not admit any fault or guilt with respect to the
subject matter of such proceeding.

         SECTION 3.09. Contribution. (a) If the indemnification provided
for herein is for any reason unavailable to the Indemnified Parties in
respect of any losses, claims, damages or liabilities referred to herein,
then each such Indemnifying Party, to the extent permitted by applicable
law, in lieu of indemnifying such Indemnified Party, shall contribute to
the amount paid or payable by such Indemnified Party as a result of such
losses, claims, damages or liabilities (i) as between the Company and any
Selling Holder 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 such Selling Holder on the one hand and the Underwriters on
the other from the offering of the securities, or if such allocation is not
permitted by applicable law, in such proportion as is appropriate to
reflect not only the relative benefits but also the relative fault of the
Company and such Selling Holder 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 any Selling Holder on the other, in such proportion as is appropriate
to reflect the relative fault of the Company and of such 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
any Selling Holder 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 such Selling Holder 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 any Selling Holder 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 such
Selling Holder or by the Underwriters. The relative fault of the Company on
the one hand and any 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.

         (b) The Company and each Selling Holder agree that it would not be
just and equitable if contribution pursuant to this Section 3.09 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 3.09, 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 underwriters' 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.

         SECTION 3.10. 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 3.11. Rule 144. If the Company shall have filed a
registration statement pursuant to the requirements of Section 12 of the
Exchange Act or a registration statement pursuant to the requirements of
the Securities Act relating to any class of equity securities, the Company
covenants that it will file any reports required to be filed by it under
the Securities Act and the Exchange Act and will take such further action
as the Selling Holder shall reasonably request, all to the extent required
from time to time to enable the Selling 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 Rule is amended from time to time, or (b) any similar rule or
regulation hereafter adopted by the Commission.

         SECTION 3.12. Holdback Agreements. (a) Restrictions on Public Sale
by Holders. If and to the extent requested of all shareholders of the
Company by the lead Underwriter of an underwritten public offering of
equity securities of the Company, the Holders agree not to effect, except
as part of such registration, any offer, sale, pledge, transfer or other
distribution or disposition or any agreement with respect to the foregoing,
of the issue being registered or 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, during the seven day
period prior to, and during such period that the lead Underwriter may
reasonably request, no greater than 90 days (or 180 days following the
Initial Public Offering), beginning on, the effective date of such
registration statement.

          (b) Restrictions on Public Sale by the Company. The Company
agrees (i) not to effect any public sale or distribution of any securities
similar to those being registered in accordance with Section 3.01 or
Section 3.02, or any securities convertible into or exchangeable or
exercisable for such securities, during the seven days prior to, and during
such period as the lead Underwriter may reasonably request, no greater than
90 days (or 180 days following the Initial Public Offering), beginning on,
the effective date of any registration statement (except as part of such
registration statement and except pursuant to registrations on Form S-4 or
S-8 or any successor or similar form thereto); and (ii) that any agreement
entered into after the date of this Agreement pursuant to which the Company
issues or agrees to issue any privately placed securities shall contain a
provision under which holders of such securities agree not to effect any
public sale or distribution of any such securities during the periods
described in (i) above, in each case including a sale pursuant to Rule 144
(except as part of any such registration, if permitted).

         SECTION 3.13. Transfer of Registration Rights. The rights of each
Holder under this Article 3 are transferable to each transferee of such
Holder to whom the transferor assigns its rights pursuant to a Transfer
that complies with the terms of Section 2.01(c).

                                 ARTICLE 4

                             PRE-EMPTIVE RIGHTS

         SECTION 4.01. Pre-emptive Rights. (a) Prior to the Initial Public
Offering, if the Company shall propose to issue or sell New Securities (as
hereinafter defined) or enter into any contracts, commitments, agreements,
understandings or arrangements of any kind relating to the issuance or sale
of any New Securities, in any such case the primary purpose of which (as
determined in good faith by the Company's Board of Directors) is for the
Company to raise capital, then the Company's Board of Directors shall
consider in good faith the desirability and appropriateness of permitting
the Holders to participate in such offerings of New Securities (the
"Preemptive Rights") including granting each Holder the right to purchase
up to that number of New Securities, at the same price and on the same
terms proposed to be issued or sold by the Company, so that each Holder
would, after the issuance or sale of all such New Securities, hold the same
proportionate interest of the issued and outstanding equity securities of
the Company (calculated a fully-diluted basis) as was held by each Holder
(on a fully-diluted basis) immediately prior to the issuance or sale of
such New Securities (the "Proportionate Percentage"). "New Securities"
means any Common Stock or options, warrants or other securities or rights
convertible or exchangeable into or exercisable for any Common Stock or any
other such equity securities; provided, however, that "New Securities"
shall not include: (i) any securities issued or issuable on conversion of
the Convertible Subordinated Notes or pursuant to the exercise of any
rights, warrants, options or other agreements outstanding on the date of
this Agreement including, without limitation, any security convertible or
exchangeable, with or without consideration, into or for any stock, options
and warrants; (ii) options and securities issued to management, directors
or employees of the Company or its Subsidiaries in the ordinary course of
business and equity securities issuable upon exercise thereof; or (iii)
securities issued in consideration for, or in connection with, any merger,
consolidation or other acquisition of all or substantially all of the
assets constituting a business.

          (b) The Company shall give each Holder written notice of its
intention to issue and sell New Securities, describing the type of New
Securities, the price and the general terms and conditions upon which the
Company proposes to issue the same. If the Company's Board of Directors
decides to grant the Holders Preemptive Rights, each Holder shall have 10
days from the giving of such notice to agree to purchase all (or any part)
of its Proportionate Percentage of New Securities for the price and upon
the terms and conditions specified in the notice by giving written notice
to the Company and stating therein the quantity of New Securities to be
purchased. In the event that fewer than all Holders elect to purchase their
portion of the New Securities in the manner described above, those Holders
electing to purchase New Securities shall be offered the opportunity to
purchase the unsubscribed portion, pro rata on the basis of the number of
shares of Common Stock owned by each such Holder (on an as-converted
basis).

          (c) If the Holders fail to exercise in full their Preemptive
Rights within such 10 days, the Company shall have 90 days thereafter to
enter into a binding agreement to sell the remainder of the New Securities
in respect of which such Holders' Preemptive Rights were not exercised, at
a price and upon general terms and conditions no more favorable to the
purchasers thereof than specified in the Company's notice to the Holders
pursuant to clause (b) of this Section 4.01. If the Company has not entered
into a binding agreement to sell the New Securities within such 90 days,
the Company shall not thereafter agree to issue or sell any New Securities,
without again offering each Holder the right to purchase its Proportionate
Percentage of the New Securities in the manner provided above.

          (d) Notwithstanding anything in this Agreement to the contrary,
each Holder shall have the right to assign its rights under this Article 4
to one or more of its Affiliates; provided that each such Affiliate shall
have agreed to be bound by the terms of this Agreement.

                                 ARTICLE 5

      BOARD APPOINTMENT OBLIGATION; INFORMATION RIGHTS; VOTING RIGHTS

         SECTION 5.01. Board Appointment Obligation. (a) For so long as the
initial Holders beneficially own Equity Securities representing at least
50% of the number of shares of Common Stock (on an as-converted basis)
initially acquired by such Holders, such Holders shall have the right to
designate one person reasonably acceptable to the Company (the "H&F
Designee") for nomination as director to the board of directors (the
"Board") of the Company. The Company hereby agrees to (i) include the H&F
Designee as one of the nominees to the Board on each slate of nominees for
election to the Board proposed by management of the Company, (ii) to
recommend the election of the H&F Designee to the shareholders of the
Company, and (iii) without limiting the foregoing, to otherwise use its
best efforts to cause the H&F Designee to be elected to the Board. The
Company hereby agrees to use its best efforts to cause the appointment of
the H&F Designee to the Finance Committee of the Board. The initial H&F
Designee shall be F. Warren Hellman.

         (b) In the event that the H&F Designee for any reason ceases to
serve as a director during his term of office, to the extent Holders are
entitled to designate an H&F Designee, the resulting vacancy on the Board
shall be filled by a director designated by the initial Holders reasonably
acceptable to the Company.

         SECTION 5.02. Information Rights. Subject to appropriate
confidentiality arrangements, the Company will provide HFCP IV, or such
other Holder as the Holders shall designate:

         (a) as soon as available and in any event within 90 days after the
end of each fiscal year of the Company, a balance sheet of the Company as
of the end of such fiscal year and the related statements of profit and
loss and cash flows for such fiscal year, setting forth in each case in
comparative form the figures for the previous fiscal year, and accompanied
by a report thereon of Ernst & Young LLP or other independent public
accountants of nationally recognized standing;

         (b) as soon as available and in any event within 45 days after the
end of each of the first three quarters of each fiscal year of the Company,
a balance sheet of the Company as of the end of such quarter and the
related statements of profit and loss and cash flows for such quarter and
for the portion of the Company's fiscal year then ended, setting forth in
each case in comparative form the figures for the corresponding quarter and
the corresponding portion of the Company's previous fiscal year, all
certified (subject to normal year-end adjustments) as to fairness of
presentation, consistency and, except for the absence of footnotes,
generally accepted accounting principles by the chief financial officer or
the chief accounting officer of the Company;

         (c) to the extent prepared by the Company and provided to
management of the Company, as soon as available and in any event within 10
days after the end of each month, a balance sheet of the Company as of the
end of such month and the related statements of profit and loss and cash
flows for such month, setting forth in each case, in comparative form the
figures for the corresponding month of the Company's previous fiscal year;
and

         (d) simultaneously with the delivery of each set of financial
statements referred to in clauses (a) and (b) above, a certificate of the
chief financial officer or the chief accounting officer of the Company
stating whether any Event of Default exists on the date of such certificate
and, if any Event of Default then exists, setting forth the details thereof
and the action which the Company is taking or proposes to take with respect
thereto.

         SECTION 5.03. Additional Rights of the Holders. For so long as the
initial Holders beneficially own Equity Securities representing at least
25% of the number of shares of Common Stock (on an as-converted basis)
initially acquired by such Holders, promptly upon a request by any Holder
to the chief executive officer, the chief financial officer, the general
counsel or the chief information officer of the Company, the Company will,
subject to appropriate confidentiality arrangements, provide reasonable
access at reasonable times to such aforementioned officers of the Company
and the Company's public accountants to discuss such financial, operating
and other information regarding the business of the Company and its
Subsidiaries as such Holder may reasonably request.

         SECTION 5.04. Voting Rights. If the Board of Directors of the
Company approves an exemption for any Person from the limitation on voting
rights set forth in Section C(2) of Article Fourth of the Company
certificate of incorporation (other than an exemption granted in connection
with the establishment of a strategic alliance with another exchange or
similar market), the Company shall simultaneously grant a similar exemption
to the holders of the Equity Securities and shall use its best efforts to
obtain the concurrence of the Securities and Exchange Commission with
respect thereto.

any other right, power or privilege.

          (b) Neither this Agreement nor any term or provision hereof may
be amended or waived in any manner other than by instrument in writing

through 3.09 shall survive any such termination.

         SECTION 6.04. Successors, Assigns, Transferees. The provisions of

agreement with respect to any of its debt or equity securities granting any
registration rights to any Person, except for an agreement with the NASD.

         SECTION 6.07. Severability. The invalidity or unenforceability of

being intended that all rights and obligations of the parties hereunder
shall be enforceable to the fullest extent permitted by law.

of assets, distribution to stockholders or combination of the shares of

         SECTION 6.09. Specific Performance. The parties hereto agree that
if any of the provisions of this Agreement were not performed in accordance
with their specific terms or were otherwise breached, irreparable damage
would occur, no adequate remedy at law would exist and damages would be
difficult to determine, and that the parties shall be entitled to specific
performance of the terms hereof and immediate injunctive relief, without
the necessity of proving the inadequacy of money damages as a remedy, in
addition to any other remedy at law or equity.

         SECTION 6.10. Other Agreements. Nothing contained in this

transfer of shares of Common Stock or other securities of the Company or
any direct or indirect subsidiary of the Company imposed by, any other
agreement.

         SECTION 6.11. New York Law. This Agreement shall be governed by
and construed in accordance with the laws of the State of New York without
giving effect to the conflicts of laws principles thereof.

         SECTION 6.12. Counterparts. This Agreement may be executed in any

instrument.
