holding entities established by such holders, if so elected by such holders) at
the time of the issuance of such Subsidiary Warrants and be dated the date of
such issuance.

          SECTION 1.2.  Sale and Purchase.  Subject to the terms and conditions
hereof (including without limitation the previous consummation of the
Transformation), the Company hereby agrees (a) to issue and sell to the
Investors, at the Closing, the Shares and the Parent Warrants, and to enter into

to issue to the holders of the related Subsidiary Stock Purchase Rights, in the

times hereinafter set forth, the Subsidiary Warrants (if any), for an aggregate
purchase price of $90,000,000 with respect to the purchase of all the foregoing
securities (the "Purchase Price"), payable to the Company at the Closing (on its
own behalf with respect to its sale of Shares, Parent Warrants and Replacement
Warrants (if any), and as agent for each Operating Subsidiary with respect to
such Operating Subsidiary's sale of its Subsidiary Stock Purchase Rights,
Subsidiary Warrants (if any) and IPO Valuation Warrants (if any), in the
respective amounts determined pursuant to the Allocation), and, subject to the
terms and conditions hereof, the Investors agree to pay the Purchase Price to
the Company at the Closing (with respect to the purchase of Shares, Parent
Warrants, Replacement Warrants (if any), Subsidiary Stock Purchase Rights,
Subsidiary Warrants (if any) and IPO Valuation Warrants (if any), in the
respective amounts determined pursuant to the Allocation), in each case in
consideration of the present or future receipt, as applicable, of the foregoing
securities.  No later than two business days prior to the Closing, the Company
and Silver Lake will inform each other of their respective bank accounts to be
used for the making of payments at the Closing.

          SECTION 1.3.  Working Capital; Certain Distributions.  (a)  Following
the date hereof and prior to the earliest to occur with respect to an Operating
Subsidiary of (i) the consummation of its Pre-Spin-Off IPO, (ii) the
consummation of its Spin-Off, (iii) the consummation of the sale (whether by
issuance or sale of stock, by sale of assets, by merger or by another
transaction) to a Person or Persons, other than the Company, any of its
Subsidiaries, Silver Lake or any of its Affiliates controlled by or under common
control with Silver Lake, of a

                                       5
<PAGE>

majority of the assets of such Operating Subsidiary or a majority of the
outstanding voting stock of an Operating Subsidiary in a single transaction or
series of related transactions (a "Third-Party Sale") and (iv) the date of the
issuance of Replacement Warrants in respect of such Operating Subsidiary's
Subsidiary Stock Purchase Rights (the earliest to occur of the events specified
in clauses (i), (ii), (iii) and (iv) above being referred to herein as the
"Specified Date"), none of the Company or any of its other Subsidiaries or other
controlled Affiliates will enter into any transaction, contract, agreement or
other arrangement (including, without limitation, the acquisition of any
securities or modification to the terms of any existing securities, but
excluding transactions provided for in the Transformation Agreement and any
other transactions, contracts, agreements or arrangements which are,
individually and in the aggregate, de minimis in nature) with such Operating
Subsidiary unless such transaction, contract, agreement or other arrangement is
effected on an arms'-length basis (from the applicable Operating Subsidiary's
perspective) and on terms and conditions which are consistent with those
transactions, contracts, agreements or other arrangements generally entered into
by similarly situated subsidiaries having third-party investors; provided,
however, that nothing contained in this Section 1.3(a) shall apply to any
transaction to which Section 1.3(c) applies.

          (b) The Company may, subject to the following provision, invest cash
or other assets in an Operating Subsidiary (in addition to the contributions
provided for in the Transformation Documents) to fund its working capital needs
or for such other bona fide business reasons (e.g., to fund acquisitions or meet
spinoff regulatory ruling requirements) as the Board of Directors of the Company
(the "Board") determines in good faith.  To the extent that the value of such
investments made by the Company (or any of its other Subsidiaries) following the
Closing Date exceeds $5,000,000 in the aggregate with respect to an Operating
Subsidiary, (the amount of any such excess, a "Working Capital Contribution"),
such Operating Subsidiary may, in exchange for such Working Capital
Contribution, issue debt or equity to the Company. Prior to the Specified Date
with respect to an Operating Subsidiary, the Company agrees to consult with
Silver Lake prior to making a Working Capital Contribution to an Operating
Subsidiary concerning whether the Operating Subsidiary will issue equity or
debt; the Company acknowledges that Silver Lake would prefer (i) that each
Operating Subsidiary fund its working capital and other financing needs from its
own cash and cash-equivalents rather than receiving a Working Capital
Contribution, and (ii) that in the event a Working Capital Contribution is made,
that the Operating Subsidiary to which it is made issue debt that is not
convertible into common stock of the Operating Subsidiary (rather than such
Operating Subsidiary issuing equity or debt convertible into equity).  The
parties agree that the principal consideration in making the decision whether an
Operating Subsidiary will issue debt or equity will be the interests of the
Operating Subsidiary.  In the event that, prior to the Specified Date with
respect to an Operating Subsidiary, equity is issued by such Operating
Subsidiary to the Company or any of its other Subsidiaries in exchange for a
Working Capital Contribution, the Company agrees that the equity will be in the
form of additional securities (rather than in the form of a modification to the
conversion price or

                                       6
<PAGE>

other terms of existing securities held by the Company in such Operating
Subsidiary). In the event that an Operating Subsidiary issues common stock or
securities convertible into common stock to the Company or any of its other
Subsidiaries prior to the Specified Date applicable to such Operating
Subsidiary, the Company will deliver written notice thereof to the holders of
the Subsidiary Stock Purchase Rights relating to such Operating Subsidiary
(including the terms of such Working Capital Contribution and the purpose
therefor, and the terms of the securities to be issued), and the Company shall,
upon the request of the Investor Representative on behalf of the holders of the
Subsidiary Stock Purchase Rights relating to such Operating Subsidiary (made
within five business days following the receipt by such holders of such written
notice), amend the terms of the Subsidiary Stock Purchase Rights to permit the
holders thereof to purchase the same percentage of the common stock of the
Operating Subsidiary (calculated assuming the conversion of any securities
convertible into common stock) following such issuance as prior to such
issuance. In connection with such an amendment, the aggregate purchase price
under the Subsidiary Stock Purchase Rights relating to such Operating Subsidiary
shall be increased ratably by an amount equal to the product of (i) the value of
the Working Capital Contribution, multiplied by (ii) a fraction the numerator of
which is the number of additional shares of common stock issuable under such
Subsidiary Stock Purchase Rights as amended (the "New Shares") and the
denominator of which is the number of shares of common stock issued to the
Company or its other Subsidiary (calculated assuming the conversion of any
securities convertible into common stock). The Company will provide the holders
of such Subsidiary Stock Purchase Rights with reasonable advance notice of any
such issuance. Any disagreements between the Company and the Investor
Representative (on behalf of the holders of such Subsidiary Stock Purchase
Rights) concerning the value of any Working Capital Contribution (other than
cash and marketable securities) or the other calculations provided for in this
Section 1.3(b) shall be determined pursuant to the Dispute Resolution Mechanism.
Except as provided in this Section 1.3(b), following the date hereof and prior
to the Specified Date applicable to an Operating Subsidiary, the Company shall
not, directly or indirectly (including through its Affiliates), (i) acquire
additional securities of such Operating Subsidiary, (ii) or modify the terms and
conditions of existing securities of such Operating Subsidiary that it holds in
any manner that dilutes the holders of such Operating Subsidiary's Subsidiary
Stock Purchase Rights, in each case without the consent of the Majority
Investors.

          (c)  In the event that, following the date hereof and prior to the
consummation of an Operating Subsidiary's Pre-Spin-Off IPO, such Operating
Subsidiary distributes to the Company or any other Subsidiary of the Company any
cash or other assets of such Operating Subsidiary (other than any such
distributions constituting a Purchase Right Flip-Up Event hereunder) (i)
comprised of any lines of business, product lines, or material contracts
(defined for this purpose as the distribution or termination with replacement at
the Company or another Subsidiary of a contract or group of related contracts
under which more than $500,000 of revenues were obtained during the preceding
twelve-month period), or (ii) otherwise constituting

                                       7
<PAGE>

in excess of $5,000,000 of distributed value in the aggregate with respect to
any Operating Subsidiary from the date hereof through the consummation of its
Pre-Spin-Off IPO, in either case without payment of fair value (provided that
the repayment of indebtedness in accordance with its terms shall constitute fair
value) therefore, (A) the Company will deliver written notice thereof to the
holders of the Subsidiary Stock Purchase Rights and IPO Valuation Warrants
relating to such Operating Subsidiary (including the terms of such distribution
and the reason therefor), and the Company shall, upon the request of the
Investor Representative on behalf of the holders of the Subsidiary Stock
Purchase Rights and IPO Valuation Warrants relating to such Operating Subsidiary
(made within five business days following the receipt by such holders of such
written notice), amend such Subsidiary Stock Purchase Rights and IPO Valuation
Warrants to reduce ratably the aggregate purchase prices payable thereunder (but
not the number of shares issuable thereunder) to reflect the amount by which the
value (if any) paid by the Company or such other Subsidiary of the Company for
the cash or assets so distributed falls short of the fair value of such cash or
other assets distributed, and (B) in the event that such distribution materially
affects the valuation of such Operating Subsidiary (as initially reasonably
determined by the Company in good faith as notified by the Company to the
Investors in writing in connection therewith, provided that such determination
shall be made pursuant to the Dispute Resolution Mechanism if the holders of a
majority of the Subsidiary Stock Purchase Rights relating to such Operating
Subsidiary do not agree with such determination), new warrants for the purchase
of Common Stock shall be issued to the holders of the applicable Subsidiary
Stock Purchase Rights and IPO Valuation Warrants (or to additional holding
entities established by such holders for the purpose of holding such new
warrants, if so elected by such holders) by the Company if such assets have been
distributed to the Company, or the Company shall cause new subsidiary stock
purchase rights to be issued to the holders of the applicable Subsidiary Stock
Purchase Rights and IPO Valuation Warrants (or to additional holding entities
established by such holders for the purpose of holding such new warrants, if so
elected by such holders) by the Subsidiary of the Company to which such business
has been distributed or contributed (and such subsidiary stock purchase rights
Subsidiary thereafter shall be deemed an "Operating Subsidiary" for purposes of
this Agreement), if such business has been distributed to a Subsidiary of the
Company or contributed by the Company to another Subsidiary (provided that such
Subsidiary is not itself an Operating Subsidiary). The terms of any such new
stock purchase rights or warrants (including the purchase prices thereunder and
the number of shares issuable thereunder) shall initially be reasonably
determined by the Company in good faith on a equitable basis designed to provide
the same aggregate value for the applicable remaining Subsidiary Stock Purchase
Rights and IPO Valuation Warrants and the new stock purchase rights or warrants
issued by the Company or one of its Subsidiaries (as applicable) immediately
following such distribution and/or contribution as the value of the Subsidiary
Stock Purchase Rights and IPO Valuation Warrants immediately prior to such
distribution. The Company shall notify the holders of the applicable Subsidiary
Stock Purchase Rights and IPO Valuation Warrants in writing of an initial
determination made by the Company under the immediately preceding two sentences
(including

                                       8
<PAGE>

all calculations relating to such determination set forth in reasonable detail
and any material underlying documentation relating to such calculations), and if
the Investor Representative on behalf of the holders of a majority of such
Subsidiary Stock Purchase Rights and IPO Valuation Warrants does not object to
such determination by providing written notice to the Company of such objection
within five business days following the receipt of the Company's notice
containing such determination, such determination shall be final and conclusive
for all purposes and be binding on all holders of such Subsidiary Stock Purchase
Rights and IPO Valuation Warrants. If holders of a majority of such Operating
Subsidiary's Stock Purchase Rights and IPO Valuation Warrants do so object in a
timely fashion, the terms of any adjustment to such Subsidiary Stock Purchase
Rights IPO Valuation Warrants and any newly issued warrants or stock purchase
rights to be issued by the Company or one of its Subsidiaries as contemplated by
this Section 1.3 (c) shall be determined pursuant to the Dispute Resolution
Mechanism.

          (d)  In the event that, prior to the consummation of an Operating
Subsidiary's Pre-Spin-Off IPO (i) with respect to any securities held by the
Company which are convertible into common stock of such Operating Subsidiary
(e.g., the convertible preferred stock described in Section 3.2(b), (c), (d) or
(e) hereof, as applicable), the number of shares of common stock into which such
convertible securities are convertible shall increase following the date of
issuance of such securities (by reason of "pay-in-kind" dividends, accruals to
the conversion value or similar events which dilute the holders of such
Operating Subsidiary's Subsidiary Stock Purchase Rights), then the shares of
common stock of such Operating Subsidiary issuable pursuant to each of its
Subsidiary Stock Purchase Rights and IPO Valuation Warrants shall be increased
(by amendment to the terms of such securities) by a number of shares of common
stock sufficient to prevent the dilution that would otherwise result to the
holders thereof (without an increase to the aggregate purchase price payable
thereunder).

          SECTION 1.4.  Investor Right to Participate in Third-Party Investments
in Operating Subsidiaries; Certain Adjustments.  (a)  In the event that, prior
to the Specified Date applicable to any Operating Subsidiary, (i) any investment
is to be made in such Operating Subsidiary (whether through the purchase of
equity securities, debt securities or otherwise, but excluding the investment by
Compaq Computer Corporation or one of its Affiliates of $14 million in the Class
B Convertible Preferred Stock of Aprisma pursuant to documentation substantially
in the form provided to Silver Lake prior to the date of this Agreement (the
"Compaq Investment"), and excluding any bona fide credit facilities established
by such Operating Subsidiary with third-party lenders) by a Person or Persons
(the "Third-Party Investors") (excluding the Company and its Subsidiaries, and
excluding Silver Lake or any of its Affiliates controlled by or under common
control with Silver Lake), (ii) any agreement is entered into between the
Company or any of its Affiliates and any Third Party Investor to make such an
investment (or any such investment is otherwise effected) prior to the second
anniversary of the Closing Date and (iii) Silver Lake or any of its Affiliates
(including without limitation any of the

                                       9
<PAGE>

members thereof) has materially assisted the Company or any of its Affiliates in
connection with the sourcing or execution of such third-party investment (an
"Applicable Third-Party Investment"), then in such event each of the Investors
will have the right (but not the obligation) to participate (or to permit one or
more of its Affiliates to participate) in such investment as provided in this
Section 1.4; provided, however, that the provisions of this Section 1.4 shall
not apply to (A) the issuance of stock options to directors, officers, employees
or consultants of the Company or any of its Subsidiaries or any subsequent
issuances of capital stock pursuant to the exercise thereof, or the issuance of
restricted stock to directors, officers, employees or consultants of the Company
or any of its Subsidiaries, in each case pursuant to any compensation or
incentive plans or arrangements approved by the board of directors of the
applicable Operating Subsidiary, (B) the issuance of capital stock of an
Operating Subsidiary pursuant to its Pre-Spin-Off IPO or (C) the issuance of
capital stock by an Operating Subsidiary pursuant to its acquisition of a
business or product line (excluding an acquisition solely of assets).

          (b)  In connection with each Applicable Third-Party Investment, at the
time the anticipated material terms and conditions of such investment are known
to the Company, the Company shall give an initial written notice to the Investor
Representative with respect to its intent to enter into such investment,
including (i) the identities of the Third-Party Investors and the size and
nature of the investment and (ii) the anticipated material terms and conditions
of such investment (including the date on which definitive documentation is
anticipated to be executed), and within five business days following the receipt
of such notice, the Investor Representative shall inform the Company as to which
Investors (if any) have agreed to participate in such investment (and any
Investor not so indicating its agreement to participate shall thereafter have no
right to participate in such Applicable Third-Party Investment pursuant hereto).
Thereafter, the Company shall cause the applicable Operating Subsidiary at least
two business days prior to the execution of definitive documentation relating to
such Third-Party Investment and ten days prior to the consummation thereof to
give written notice to the Investor Representative (the "Investment Notice")
setting forth the definitive material terms and conditions of such investment
(including a statement as to whether the terms and conditions differ materially
from those described in the initial written notice described above) and
attaching definitive copies of each of the agreements and other documents to be
entered into between the Company and any of its Affiliates and the Third-Party
Investors in connection with such Third-Party Investment (which agreements and
other documents shall include appropriate provisions relating to the
participation of the Investors who have previously agreed to participate in the
investment), such that such agreements and other documents may be executed by
the Investors who agreed to participate in such investment, and provided that
any representations, warranties and covenants of such Investors (or their
investment Affiliates) shall be made severally in proportion to their respective
actual participation in such investment).  In the event that any of the
consideration to be paid by the Third-Party Investors in connection with such
Applicable Third-Party Investment consists of property other than cash, such
notice also shall

                                      10
<PAGE>

also include such Operating Subsidiary's good faith and reasonable determination
of the fair market value of such property, including the calculations (in
reasonable detail) used in making such determination. The Company promptly shall
cause the applicable Operating Subsidiary to provide to the Investor
Representative such additional information as they may reasonably request (which
information previously has been provided or was otherwise available to the
Third-Party Investors) in connection with evaluating the proposed Third-Party
Investment, including without limitation information relating to the valuation
of any non-cash consideration to be paid by the Third-Party Investors.

          (c)  In connection with each Applicable Third-Party Investment, any
Investors who agreed to participate in a timely fashion following the Investor
Representative's receipt of the first written notice described in Section 1.4(b)
above) shall in the aggregate invest (or cause their respective Affiliates to
invest) in the applicable Operating Subsidiary, on the same terms and conditions
as the investment to be made by the Third-Party Investors (except as provided
below), an amount equal to the lesser of (i) 10% of the total value to be
invested in connection with such Applicable Third-Party Investment (including
the amount to be invested by the Investors and their Affiliates) or (ii) the
aggregate purchase price under the Subsidiary Stock Purchase Rights relating to
the applicable Operating Subsidiary, with each such Investor investing (or
causing its Affiliates to invest) its pro rata share of such amount (based upon
the relative ownership by such Investors making (or causing their Affiliates to
make) such investment of the Subsidiary Stock Purchase Rights relating to such
Operating Subsidiary at the time of execution of the definitive documentation
relating to such Applicable Third-Party Investment), provided that, in the event
that the definitive terms and conditions included in the Investment Notice and
the definitive documentation for such investment differ in any material respect
from the anticipated terms and conditions set forth in the first written notice
described in Section 1.4(b) above, each Investor originally agreeing to
participate (or to cause its Affiliates to participate) in such investment shall
have the right to opt out of such investment within two business days following
its receipt of the Investment Notice; provided, however, that, in the event the
Third-Party Investors are to invest any property other than cash, such property
will be valued (A) at the value set forth in the Investment Notice, in the case
of non-cash consideration having an aggregate value of $1 million or less, (B)
at the price at which such non-cash consideration is valued by the Third-Party
Investors for purposes of cash sales to third-parties in the ordinary course of
their businesses (if applicable), or in the case of other property that has an
independent third-party valuation, at such valuation (provided in each case that
such valuation is the valuation being used by the Company for purposes of
valuing such consideration), or (C) otherwise at its fair market value as set
forth in the Investment Notice, if the Investor Representative on behalf of the
Investors does not object within five business days of its receipt of the
written notice of such valuation from the Company, or as determined pursuant to
the Dispute Resolution Mechanism, in the case of such an objection, and in each
case the Investors (or their Affiliates designated by such Investors) will have
the right to make their allocable

                                      11
<PAGE>

portion of such investment in cash; and provided, further, that, in the event
that any Investor elects not to participate (or to permit its Affiliates to
participate) in such Third-Party Investment, the other Investors shall have the
right to make an additional investment (in addition to their respective pro rata
original shares of such investment) equal to their respective pro rata shares of
such declined portion of the investment (such that the investing Investors (and
their Affiliates) as a group shall have the right to invest the entire aggregate
investment amount originally available to the Investors); and provided, further,
that the rights described in this Section 1.4 shall be incremental to, and not
in replacement of, the right of the Investors subsequently to purchase common
stock pursuant to the Subsidiary Stock Purchase Rights relating to such
Operating Subsidiary.

          (d)  If one or more of the Investors elects to participate (or to
permit one or more of its Affiliates to participate) in the Third-Party
Investment by delivery to the Company of an irrevocable written notice not less
than two business days prior to the date set forth in the Investment Notice for
the execution of definitive documentation indicating such Person's exercise of
its rights under this Section 1.4 and setting forth the dollar amount of its
investment commitment (including whether it desires to make any additional
investment to the extent that other Investors decline to participate (or permit
their Affiliates to participate) in such investment), then the Company shall
cause the applicable Operating Subsidiary to enter into with such electing
Investors (or their Affiliates designated by such Investors) the definitive
agreements and other documents relating to such Applicable Third-Party
Investment at the time such agreements and other documents are entered into with
the Third-Party Investors (provided that any material changes to such agreements
and other documents from the forms thereof attached to the Investment Notice
shall result in the Investors having an additional two business days from their
receipt of a supplemental written notice setting forth such changes to determine
whether to continue to participate in such investment); provided, however, that
the Company shall cause the applicable Operating Subsidiary to make such changes
to the agreements and other documents relating to such Third-Party Investment
(solely for purposes of the investment to be made by the Investors or their
Affiliates) as may be reasonably requested in good faith in writing by any of
the Investors (or Affiliates thereof) participating in such investment prior to
execution thereof to the extent that such changes are required for regulatory
reasons particular to such investors (e.g, venture capital operating company
considerations) or otherwise to reflect factual circumstances particular to such
investors (e.g., required time periods for capital drawdowns or "phantom income"
considerations), provided that any such changes are not materially adverse to
the Company or its Subsidiaries.

          (e)  The Company agrees that, in the event that prior to the Specified
Date applicable to an Operating Subsidiary, any shares of capital stock or
securities exercisable or exchangeable for or convertible into shares of capital
stock of such Operating Subsidiary are

                                      12
<PAGE>

issued or granted to any Person (other than (i) pursuant to a Working Capital
Contribution, (ii) securities issued to Silver Lake or any of its Affiliates
controlled by or under common control with Silver Lake and (iii) grants of
employee options and issuances of shares upon the exercise of such employee
options), such issuance or grant shall be dilutive to the Company with respect
to its ownership of capital stock in such Operating Subsidiary on a pro rata
basis with the dilution to the holders of such Operating Subsidiary's Subsidiary
Stock Purchase Rights and IPO Valuation Warrants (unless the Majority Investors
shall otherwise consent in writing).

          (f)  The parties hereto acknowledge and agree that the aggregate
number of shares of common stock of each Operating Subsidiary that will be
issuable as of the Closing pursuant to the Subsidiary Stock Purchase Rights
relating to such Operating Subsidiary (as set forth on Schedule A hereto) has
been determined based upon a number of outstanding employee options as of the
Closing equal to 20.0% of the diluted capital stock of such Operating Subsidiary
(counting for such purpose all capital stock of such Operating Subsidiary to be
owned as of the Closing by the Company, to be issued in connection with the
Compaq Investment (in the case of Aprisma), issuable pursuant to the exercise of
such employee options and issuable pursuant to such Subsidiary Stock Purchase
Rights), and the aggregate number of shares of common stock of such Operating
Subsidiary issuable pursuant to its Subsidiary Stock Purchase Rights shall not
be reduced in the event that any or all of such employee options, shares
issuable pursuant to the exercise thereof or shares issuable to Compaq (in the
case of Aprisma) have not been issued as of or at any time following the
Closing.  The parties hereto further agree that, in the event that as of
immediately prior to the purchase of common stock under the Subsidiary Stock
Purchase Rights relating to an Operating Subsidiary, the number of shares of
capital stock issuable pursuant to outstanding options, warrants or other
securities or rights convertible into or exercisable for capital stock or other
securities of such Operating Subsidiary (whether or not then vested or otherwise
exercisable) that are then held by directors, officers, employees or consultants
of the Company or any of its Affiliates, together with all shares of capital
stock previously issued upon the exercise of any such securities or rights or
otherwise previously granted or issued to directors, officers, employees or
consultants of the Company or any of its Affiliates, exceeds 20.0% of the then-
existing diluted capital stock of such Operating Subsidiary (the total number of
such shares of capital stock, the "Outstanding Employee Shares" of such
Operating Subsidiary, and the number of such shares of capital stock in excess
of such 20.0% level, the "Outstanding Incremental Employee Shares" of such
Operating Subsidiary), the number of shares of such Operating Subsidiary's
common stock issuable pursuant to the purchase of common stock under its
Subsidiary Stock Purchase Rights shall be increased (ratably among its Callable,
First-Tier, Second-Tier and Third-Tier Optional Subsidiary Stock Purchase Rights
based upon the number of shares of common stock previously issuable pursuant
thereto, and without any increase in the aggregate exercise prices under any of
such Subsidiary Stock Purchase Rights) as follows:

                                      13
<PAGE>

     (i) With respect to Outstanding Incremental Employee Shares which cause the
total number of Outstanding Employee Shares to be in excess of 20.0% but less
than or equal to 23.0% of the diluted capital stock of such Operating Subsidiary
(taking into account the additional shares issuable pursuant to this Section
1.4(f)), the number of shares of such Operating Subsidiary's common stock
issuable pursuant to the purchase of common stock under its Subsidiary Stock
Purchase Rights shall be increased by the number of shares equal to the product
of (A) .50, multiplied by (B) the number of shares of common stock required to
prevent the shares of common stock issuable under such Operating Subsidiary's
Subsidiary Stock Purchase Rights from decreasing as a percentage of the diluted
capital stock of such Operating Subsidiary as a consequence of the Outstanding
Incremental Employee Shares of such Operating Subsidiary described in this
subsection (i); and

     (ii) With respect to Outstanding Incremental Employee Shares which cause
the total number of Outstanding Employee Shares to be in excess of 23.0% of the
diluted capital stock of such Operating Subsidiary (taking into account the
additional shares issuable pursuant to this Section 1.4(f)), the number of
shares of such Operating Subsidiary's common stock issuable pursuant to the
purchase of common stock under its Subsidiary Stock Purchase Rights shall be
further increased by the number of shares of common stock required to prevent
the shares of common stock issuable under such Operating Subsidiary's Subsidiary
Stock Purchase Rights from decreasing as a percentage of the diluted capital
stock of such Operating Subsidiary as a consequence of the Outstanding
Incremental Employee Shares of such Operating Subsidiary described in this
subsection (ii)

Schedule 1.4(f) hereto sets forth examples that illustrate the anti-dilution
calculations described above in Sections 1.4(f)(i) and (ii).  The examples
contain assumptions concerning the number of Outstanding Incremental Employee
Shares at the time calculations are to be made under this Section 1.4(f) and the
number of additional shares previously issued to the Company, the Investors and
third parties.  The actual number of Outstanding Incremental Employee Shares and
the number of additional shares issued to the Company, the Investors and third
parties after the date  hereof would be used in performing the calculations
described above.

          SECTION 1.5.  Flip-Up Events; Issuance of Replacement Warrants.  (a)
In the event that, prior to the time an Operating Subsidiary consummates the
earlier of a Pre-Spin-Off IPO, Spin-Off or Third-Party Sale, (i) the Company
determines to recombine a majority of the assets of such Operating Subsidiary
with the Company in a single transaction or series of related transactions, (ii)
the Company (A) informs the holders of such Operating Subsidiary's Subsidiary
Stock Purchase Rights in writing that such Operating Subsidiary no longer has a
present intention to engage in a Pre-Spin-Off IPO, a Spin-Off or a Third-Party
Sale or (B) the Company

                                      14
<PAGE>

grants or otherwise issues to the employees of such Operating Subsidiary options
or other rights to acquire capital stock of the Company in consideration
(directly or indirectly) of the cancellation or other relinquishment of
substantially all of such employees' options to acquire capital stock of such
Operating Subsidiary (and the Company shall notify the holders of an Operating
Subsidiary's Subsidiary Stock Purchase Rights in writing in such event), or
(iii) a third party acquires all or substantially all of the capital stock or
assets of the Company (whether by equity purchase, asset purchase, merger,
exchange offer or otherwise, and including without limitation a merger where the
Company is the survivor but the stockholders of the Company immediately prior to
such event do not own a majority of the outstanding voting power of the Company
immediately following such event) (a "Company Sale") (any event described in
clause (i), (ii) or (iii), a "Purchase Right Flip-Up Event" with respect to such
Operating Subsidiary (or, in the case of clause (iii), with respect to all
Operating Subsidiaries not having previously engaged in a Pre-Spin-Off IPO,
Spin-
Off or Third-Party Sale), the Subsidiary Stock Purchase Rights relating to such
Operating Subsidiary shall be canceled and in replacement therefor, the holders
of such Subsidiary Stock Purchase Rights shall at that time be issued by the
Company additional warrants to purchase Common Stock (the "Replacement
Warrants") having the terms described below and otherwise in the form of the
Parent Warrants; provided, however, that if, following a Purchase Right Flip-Up
Event of the type described in clause (i) or (ii) above and prior to the third
anniversary of the Closing, the Company again determines to transfer any of such
Operating Subsidiary's former businesses into a Subsidiary and engage in an
initial public offering and/or spin-off or third-party sale of such Subsidiary's
capital stock (in the case of clause (i) above), or to cause such Operating
Subsidiary to engage in a Pre-Spin-Off IPO, Spin-Off or Third-Party Sale (in the
case of clause (ii) above), the applicable Holding Partnership(s) shall be
issued new Subsidiary Stock Purchase Rights with respect to such Subsidiary on
terms equivalent to those of the Subsidiary Stock Purchase Rights previously
canceled (and any outstanding Replacement Warrants previously issued in
replacement therefor will be canceled in consideration of such issuance). The
Company agrees to use reasonable efforts in connection with any Purchase Right
Flip-Up Event to effect such event in a manner that is tax-efficient for the
recipients of Replacement Warrants (to the extent practicable).

          (b)  In connection with any Purchase Right Flip-Up Event, the Company
shall inform the holders of the related Subsidiary Stock Purchase Rights in
writing of the valuation being assigned by the Company to the Operating
Subsidiary or Operating Subsidiaries involved in such Purchase Right Flip-Up
Event (including all calculations relating to such valuation set forth in
reasonable detail and any material underlying documentation relating to such
calculations) for purposes of valuing employee options issued by such Operating
Subsidiary or Operating Subsidiaries in connection with replacing such options
with new Company employee options, if applicable, and if the Company is not
preparing a valuation for such purpose, the Company shall in good faith prepare
and deliver to such holders a reasonable valuation for the purposes of this
Section 1.5 of the applicable Operating Subsidiary or Operating Subsidiaries

                                      16
<PAGE>

(any valuation delivered by the Company under this sentence being referred to as
the "Company Valuation").  In the event that holders representing a majority of
the related Subsidiary Stock Purchase Rights notify the Company in writing
within five business days of the receipt of the Company Valuation that they do
not believe the Company's Valuation to be a reasonable valuation of the fair
market value of such Operating Subsidiary or Operating Subsidiaries then such
valuation shall be determined pursuant to the Dispute Resolution Mechanism;
provided, however, that the Company may inform the Investor Representative prior
to the preparation of a Company Valuation that the Company has determined to
retain an Investment Bank to render a Flip-Up Valuation, in which event the
Company and the Investor Representative shall together select an Investment Bank
pursuant to the Dispute Resolution Mechanism (and submit information to such
bank, to the extent applicable), and such Investment Bank's determination of the
Flip-Up Valuation shall be binding on all parties hereunder.  Subject to the
immediately preceding proviso, the Company Valuation, if uncontested by the
holders of such rights, or the valuation determined through the Dispute
Resolution Mechanism, if the Company Valuation was contested, is hereinafter
referred to as the "Flip-Up Valuation".

          (c)  The Replacement Warrants (i) will be immediately exercisable upon
issuance (provided that they shall in any event become exercisable no later than
immediately prior to the consummation of the triggering third-party acquisition,
in the case of an event described in Section 1.5(a)(iii) above), and will remain
exercisable until the later of (a) the fourth anniversary of the Closing or (b)
the first anniversary of the consummation of the Purchase Right Flip-Up Event
giving rise to the issuance of such Replacement Warrants, (ii) will have an
initial aggregate exercise price equal to the product of (A) 5, multiplied by
(B) the exercise price in effect for the related Callable Subsidiary Stock
Purchase Rights immediately prior to such Purchase Right Flip-Up Event (subject
to the following proviso), (iii) will initially be exercisable for that
percentage of the Company's diluted Common Stock equal to the product of (A)
that percentage of the diluted common stock of the Operating Subsidiary for
which the related Subsidiary Stock Purchase Rights were (or when issued, would
have been) exercisable immediately prior to the consummation of such Purchase
Right Flip-Up Event multiplied by (B) a fraction the numerator of which is the
Flip-Up Valuation and the denominator of which is the sum of the market
capitalization of the Company immediately preceding such Purchase Right Flip-Up
Event and the Flip-Up Valuation, and (iv) otherwise will be on the terms and
conditions set forth in the form of Parent Warrant; provided, however, that, in
the case of a Purchase Right Flip-Up Event described in clause (i) or clause
(ii) of the definition thereof occurring prior to the second anniversary of the
Closing, the initial aggregate exercise price of the Replacement Warrants shall
be discounted, and shall equal the product of (A) 5, multiplied by (B) the
exercise price in effect for the related Callable Subsidiary Stock Purchase
Rights immediately prior to such Purchase Right Flip-Up Event, multiplied by (C)
0.9.

          SECTION 1.6.  IPO Valuation Warrants.  (a) In the event that, at the
time an Operating Subsidiary consummates a Pre-Spin-Off IPO, the IPO Valuation
(as defined below) of such Operating Subsidiary exceeds the product of (i) the
Target Valuation for such Operating Subsidiary set forth on Schedule 1.6(a),
multiplied by (ii) 1.1, then such Operating Subsidiary shall issue (and the
Company shall cause such Operating Subsidiary to issue) to the holders of the
Subsidiary Stock Purchase Rights issued by such Operating Subsidiary (or to such
other transferees as the Investors identify to the Company in writing, subject
to the provisions of the Standstill Agreement) at the consummation of such Pre-
Spin-Off IPO additional warrants (the "IPO Valuation Warrants") to purchase
common stock of such Operating Subsidiary having the terms described below and
otherwise in the form attached hereto as Exhibit D.

          (b) As used in this Agreement, "IPO Valuation" means, with respect to
any Operating Subsidiary, the product of (i) the gross price per share of common
stock of such Operating Subsidiary paid by the public in such Operating
Subsidiary's Pre-Spin-Off IPO (such Operating Subsidiary's  "IPO Price"),
multiplied by (ii) the number of shares of common stock of such Operating
Subsidiary outstanding immediately following such Pre-Spin-Off IPO on a fully
diluted basis.

          (c) The IPO Valuation Warrants issued by an Operating Subsidiary (i)
will be exercisable from the date of issuance until the third anniversary of the
date of issuance by the applicable Operating Subsidiary, (ii) will have an
initial exercise price per share equal to the IPO Price with respect to such
Operating Subsidiary, (iii) will be exercisable for that number of shares of
common stock of such Operating Subsidiary equal to (A) the Aggregate Exercise
Price for such Operating Subsidiary set forth on Schedule 1.6(c), divided by (B)
the IPO Price with respect to such Operating Subsidiary and (iv) will otherwise
be on the terms and conditions set forth in Exhibit D hereto.

          SECTION 1.7.  Subsidiary Warrants.  (a) Upon each consummation of a
Spin-Off with respect to an Operating Subsidiary, (i) the exercise price per
share of Common Stock under each of the Class A Parent Warrants, the Class B
Parent Warrants and the Replacement Warrants then outstanding (if any) will be
adjusted downward (but not to less than $.01 per share of Common Stock) pursuant
to the provisions relating thereto contained in the warrant certificates
relating to such warrants (the amount of such downward adjustment with respect
to the exercise price for one share of Common Stock under each such warrant, its
"Strike Price Reduction"), and (ii) the holders of Parent Warrants and
Replacement Warrants (if any) (or holding entities established by such holders,
if so elected by such holders) shall be issued by the applicable Operating
Subsidiary (and the Company shall cause such issuance), in respect of each share
of Common Stock for which a Parent or Replacement Warrant (as applicable) is
exercisable, an additional warrant having the terms described below and
otherwise in the form attached as

                                      17
<PAGE>

Exhibit D hereto (the "Subsidiary Warrants") to purchase that number of shares
of common stock of such Operating Subsidiary which would have been received in
such Spin-Off in respect of such share of Common Stock underlying such Parent or
Replacement Warrant if such Parent or Replacement Warrant had been exercised in
full immediately prior to the record date for determining holders of Common
Stock entitled to participate in such Spin-Off.

          (b)  The Subsidiary Warrants issued in respect of the shares of Common
Stock for which a Parent Warrant or Replacement Warrant (as applicable) is
exercisable (i) shall be exercisable from the date of issuance until the later
of (A) the seventh anniversary of the Closing or (B) the third anniversary of
the Spin-Off in connection with which they were issued, (ii) shall have an
aggregate initial exercise price equal to the Strike Price Reduction with
respect to such Parent Warrant (in the case of Subsidiary Warrants issued in
respect of a Parent Warrant) or a Replacement Warrant (in the case of Subsidiary
Warrants issued in respect of Replacement Warrants) multiplied by the number of
shares of Common Stock for which such Parent Warrant or Replacement Warrant (as
applicable) is exercisable, (iii) shall have a per-share exercise price equal to
the aggregate exercise price for each such Subsidiary Warrant divided by the
number of shares for which such Subsidiary Warrant is exercisable and (iv)
otherwise will be on the terms and conditions set forth in Exhibit D hereto.

          SECTION 1.8.  Dispute Resolution Mechanism.  (a)  The parties hereto
acknowledge the need to resolve any disputes arising hereunder that become
subject to the following dispute resolution mechanism quickly and expeditiously,
and agree to work toward such a resolution.  In the event that any valuation or
equitable adjustment of rights relating to the procedures and transactions
described in this Article I becomes a subject of disagreement between the
holders of a majority of the rights depending upon such determination and the
Company or one of its Operating Subsidiaries, as applicable, (i) such majority
holders and the Company or such Operating Subsidiary, as applicable, promptly
(and in any event within three business days) shall provide each other with
their respective written proposed valuations or equitable adjustments of rights
(including any supporting documentation and the basis for such position), and
the Company or such Operating Subsidiary (as applicable) and Silver Lake (if it
or its Affiliates hold any such rights), or another representative appointed by
such majority holders (if Silver Lake and its Affiliates do not hold any of such
rights) (in either such case, the "Investor Representative") shall promptly (and
in any event within three business days after the receipt of the other's
respective proposed valuation or equitable adjustment) commence negotiating in
good faith to reach agreement as to an agreed-upon valuation or equitable
adjustment of rights (and any such agreement shall be binding upon the Company
or such Operating Subsidiary, as applicable, and all of the holders of the
rights depending upon such determination), and (ii) in the event that they fail
to reach agreement within five business days following commencement of such
negotiations, such valuation or equitable adjustment of rights shall be
determined as follows: (A) the Company or Operating Subsidiary, as applicable,
and the Investor

                                      18
<PAGE>

Representative promptly (and in any event within three business days thereafter)
shall together retain a nationally recognized investment banking firm (the
"Investment Bank") that has had no material business relationships with the
Company or the majority holders of the rights depending upon such determination
during the preceding one-year period (unless they shall at the time mutually
agree to select an Investment Bank having such business relationships), (B) the
Company or Operating Subsidiary, as applicable, promptly shall submit to such
Investment Bank the proposed valuation or equitable adjustment of rights that it
first provided to such majority holders (including any supporting documentation
provided to such majority holders), (C) the Investor Representative shall submit
to such Investment Bank the proposed valuation or equitable adjustment of rights
that the majority holders first provided to the Company or Operating Subsidiary,
as applicable (including any supporting documentation provided by such majority
holders), and (D) such Investment Bank promptly (but in the case of any event
described in clause (iii) of the definition of Purchase Right Flip-Up Event, no
later than two business days prior to the consummation of such event, and in any
event within ten business days, in each case to the extent reasonably achievable
by such Investment Bank) shall select whichever of such two proposed valuations
or equitable adjustments of rights is closer to its determination of the correct
valuation or equitable adjustment of rights, which selected valuation or
equitable adjustment of rights shall be binding upon the Company or such
Operating Subsidiary, as applicable, and all of the holders of the rights
depending upon such determination (with the Company or such Operating
Subsidiary, as applicable, paying the fees and expenses of the Investment Bank
if the majority holders' valuation or equitable adjustment of rights is selected
and the majority holders of such rights paying such fees and expenses if the
Company's or Operating Subsidiary's, as applicable, valuation or equitable
adjustment of rights is selected (and the other holders of such rights shall
reimburse the majority holders therefore pro rata based upon their respective
ownership of such rights)).

          (b)  In the event that the Dispute Resolution Mechanism is required to
determine any valuation or equitable adjustment of rights under this Article I,
or in the event that regulatory or other third-party approvals are required to
be obtained by any holder of rights under this Article I in connection with any
transaction, if the action to be taken by the Company that has given rise to
such dispute or need for such approvals is scheduled to be consummated prior to
completion of the resolution of such dispute pursuant to the Dispute Resolution
Mechanism or receipt of such approvals, as applicable, such action may be taken
by the Company in its discretion prior to such resolution or receipt, and the
rights of such holders under this Article I shall be preserved and shall be
effected following the consummation of such action by the Company when such
dispute has been resolved pursuant to the Dispute Resolution Mechanism or such
approvals have been obtained, as applicable.

          SECTION 1.9.  Allocation of Purchase Price.  Within forty-five days
following the Closing, the Company and Silver Lake shall cooperate in all
commercially reasonable

                                      19
<PAGE>

respects to together determine in writing the appropriate allocation of the
Purchase Price among the securities described in Section 1.2 hereof for tax
purposes (the "Allocation"). Upon completion of the Allocation, the Company
shall pay over in cash to each Operating Subsidiary (as agent for such Operating
Subsidiary, and not as a capital contribution to, or in respect of the issuance
of additional securities by, such Operating Subsidiary) that portion of the
Purchase Price that the Company received pursuant to Section 1.2 hereof as agent
for such Operating Subsidiary in respect of the sale by such Operating
Subsidiary to the Investors of such Operating Subsidiary's Subsidiary Stock
Purchase Rights, Subsidiary Warrants (if any) and IPO Valuation Warrants (if
any) hereunder.

          SECTION 1.10.  No Obligation to Engage in Spin-Offs.  The parties
hereto acknowledge and agree that the Company has no obligation to engage in any
of the Pre-Spin-Off IPOs or Spin-Offs.  The parties hereto further acknowledge
and agree that the Company shall continue to have the full right to deal with
the Operating Subsidiaries as it shall determine in its sole discretion, subject
to the express provisions of this Agreement relating to such dealings (including
Section 1.3(a) and Section 1.3(b) hereof); provided, however, that the rights of
the Investors (including the right to participate in any such transaction or
other dealing) shall be as expressly set forth herein; and provided, further,
that the Company agrees that all decisions concerning the timing of each of the
Pre-Spin-Off IPOs and Spin-Offs shall require the approval of the Board.

                                   ARTICLE II

                         CLOSING, DELIVERY AND PAYMENT

right to receive Replacement Warrants (if any), IPO Valuation Warrants (if any)
and Subsidiary Warrants (if any) (the "Closing") shall take place on August 29,
2000 at the offices of Simpson Thacher & Bartlett, 425 Lexington Avenue, New
York, New York 10017, or at such other time or place as the Company and the
Majority Investors may mutually agree (such date is referred to herein as the

and conditions hereof, (i) the Company shall deliver to the Investors all of the
Shares and all of the Parent Warrants to be purchased in accordance with Section
1.2 by delivery of certificates evidencing the Shares and the Parent Warrants
and (ii) the Company shall cause each Operating Subsidiary to deliver to the
Investors all of the Subsidiary Stock Purchase Rights to be purchased in
accordance with Section 1.2 by delivery of certificates evidencing such
Subsidiary Stock

                                      20
<PAGE>

Purchase Rights, in each case free and clear of any Encumbrances (as hereinafter
defined) other than those imposed by federal or state securities laws or created
by the Standstill Agreement or otherwise placed thereon by or on behalf of the
Investors, and the Investors shall make payment to the Company and the
applicable Operating Subsidiaries, as applicable, of the aggregate purchase
price therefor by wire transfer of immediately available funds to an account
designated by the Company to the Investors at least two busiess days prior to
the Closing Date.

          (b) In the circumstances and at the times herein set forth, subject to
the terms and conditions hereof, (i) the Company shall deliver to the holders of
the related Subsidiary Stock Purchase Rights all of the Replacement Warrants (if
any) to be issued in accordance with Section 1.2, by delivery of certificates

Subsidiary to deliver to the holders of the related Subsidiary Stock Purchase
Rights (or their transferees, subject to the transfer restrictions contained in
the Standstill Agreement), the IPO Valuation Warrants (if any) to be issued in
accordance with Section 1.2, by delivery of certificates evidencing the IPO
Valuation Warrants and (iii) the Company shall cause each Operating Subsidiary
to deliver to the holders of the Shares (or to holding entities established by
such holders, if so elected by such holders) all of the Subsidiary Warrants (if

                                  ARTICLE III

                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY

          The Company hereby represents and warrants to the Investors, as of the

the Company and each of its Subsidiaries is a corporation or other entity duly
organized, validly existing and in good standing under the laws of its

efforts to preserve intact its and its Subsidiaries' current business
organizations, keep available the services of their current officers and

          (b)  Without limiting the generality of the foregoing, during the Pre-
Closing Period, each of the Company and its Subsidiaries shall not, without the
prior consent of the Majority Investors (such consent not to be unreasonably
withheld or delayed):

hereunder, required by law or required by the rules and regulations of the New
York Stock Exchange, make any amendment to the Company's Certificate of
Incorporation or the constituent documents of any Operating Subsidiary that
would adversely affect in any material respect the rights and preferences of the
holders of the Shares, Parent Warrants, Replacement Warrants, Subsidiary Stock
Purchase Rights, IPO Valuation Warrants or Subsidiary Warrants when issued;

     (ii)  make, declare or pay any extraordinary cash dividend, other than

          SECTION 5.6.  Regulatory and Other Authorizations; Notices and

          SECTION 5.7.  Boards of Directors.  (a)  For so long as Silver Lake
and its Affiliates own in the aggregate not less than thirty-five (35%) of the
aggregate number of Shares issued to the Investors by the Company on the Closing
Date, Silver Lake shall have the right (but in no event the obligation) to
nominate for election to the Board one nominee who is a member of the general
partner or investment advisor of Silver Lake (the "Investor Company Nominee")
upon each regular election of the class of directors whose current term expires
in 2003 ("Class II").  To this end, the Company and the Investors agree to take
the following actions (unless Silver Lake shall have determined in its sole
discretion not to nominate a nominee for election to the Board or to replace an
Investor Company Nominee who has left the Board):

          (i)  As of the Closing Date, David Roux (or, in the event that David
Roux is unable to serve as the Investor Company Nominee and subject to the
standards set forth in paragraph (c) below, such other Investor Company Nominee
as Silver Lake shall notify to the Company in writing not less than five
business days prior to the Closing Date) shall be appointed to the Board as the
initial Investor Company Nominee.  Thereafter, Silver Lake shall notify the
Company in writing of the identity of the Investor Company Nominee by no later
than the same time shareholder proposals are due as set forth in the Company's
annual proxy statement filed the year preceding the year of election of Class II
members of the Board, which notice shall be conclusive evidence of the consent
of the Investor Company Nominee to serve as a director of the Company.  In the
event Silver Lake fails to provide such notice, the active director most
recently nominated by the Investors shall be deemed to be the Investor Company
Nominee.  The notice shall include all information with respect to the Investor
Company Nominee as is required to be included in a proxy statement soliciting
proxies for the election of directors pursuant to Regulation 14A under the
Exchange Act.  In the event of any vacancy on the Board arising by reason of the
Investor Company Nominee's resignation, death, removal or inability to serve,
Silver Lake shall notify the Company of their nominee to fill such vacancy, and,
subject to clause (iii) below, the Company shall use its reasonable best efforts
to cause the vacancy created thereby to be filled as soon as reasonably
possible, and to elect such nominee to serve until the next meeting of the
stockholders for the election of Class II directors of the Company.

                                      34
<PAGE>

          (ii)  Subject to clause (iii) below, the Company shall use its
reasonable best efforts to cause the Investor Company Nominee to be included in
the slate of nominees presented by the Board to the stockholders of the Company
for election as directors at each relevant annual meeting of the stockholders,
and shall use its reasonable best efforts to cause the election of the Investor
Company Nominee, including soliciting proxies in favor of the election of the
Investor Company Nominee.  Subject to clause (iii) below, the Company shall not
solicit proxies of the stockholders of the Company to vote against the Investor
Company Nominee or for the approval of any stockholder or other proposals that
are inconsistent with the rights afforded the Investors pursuant to this Section
5.7(a), and shall use its reasonable best efforts to oppose the removal of the
Investor Company Nominee from the Board.

          (iii)  As a condition precedent to election of any individual to fill
a vacancy as contemplated by the last sentence of clause (i) above and to the
inclusion of any proposed Investor Nominee to be presented to stockholders by
the Board pursuant to clause (ii) above, the Board or, if established, the
nominating committee of the Board, may review the information provided pursuant
to this Section 5.7(a) and such other information as the Board or such committee
may reasonably request in order to evaluate the Investor Company Nominee's
character and fitness to serve as a director.  If the Board or the nominating
committee, as the case may be, reasonably determines in good faith that any
Investor Company Nominee lacks the character or fitness to serve as a director
based on applicable legal and reasonable commercial standards, the Board or the
nominating committee, as the case may be, shall inform Silver Lake of such
determination, and Silver Lake shall then have the right to nominate a
substitute Investor Company Nominee (and the provisions of this Section 5.7(a)
shall apply to such subsequent Investor Company Nominee, provided that any time
periods provided for herein shall be shortened such that the subsequent Investor
Company Nominee becomes a member of the Board as soon as reasonably possible).

          (b)  Commencing at the time of the purchase of a sufficient number of
shares of common stock pursuant to (other than in connection with a Third-Party
Sale) the Subsidiary Stock Purchase Rights relating to Aprisma to result in
ownership by Silver Lake and its Affiliates of at least 2.25% of the diluted
capital stock of Aprisma (the "Designation Event") (disregarding for purposes of
measuring such percentage any issuances of Aprisma capital stock or other
securities exercisable therefor subsequent to the initial formation and
capitalization of Aprisma), and continuing until the earlier of (i) the first
anniversary of a Spin-Off of Aprisma or (ii) such time as Silver Lake and its
Affiliates no longer hold at least at least 2.25% of the diluted capital stock
of Aprisma (disregarding for purposes of measuring such percentage any issuances
of Aprisma capital stock or other securities exercisable therefor subsequent to
the initial formation and capitalization of Aprisma), Silver Lake shall have the
right (but in no event the obligation) to nominate for election to the Board of
Directors of Aprisma (the "Aprisma Board"), and the Company shall cause Aprisma
(and shall obtain Aprisma's written agreement prior to a Spin-Off

                                      35
<PAGE>

of Aprisma) to comply with the provisions of this Section 5.7(b), one nominee
who is a member of the general partner or investment advisor of Silver Lake (the
"Investor Aprisma Nominee") upon each regular election of directors of Aprisma.
To this end, the Company and the Investors agree to take the following actions
(and the Company shall cause Aprisma to take such actions) (unless Silver Lake
shall have determined in their sole discretion not to nominate a nominee for
election to the Aprisma Board or to replace an Investor Aprisma Nominee who has
left the Board):

          (i)  As of the Designation Event, such Investor Aprisma Nominee as
Silver Lake shall notify to the Company and Aprisma in writing (the person so
designated to be subject to the approval of Piyush Patel (or any successor
thereto) which approval shall not be unreasonably withheld) shall be appointed
to the Aprisma Board as the initial Investor Aprisma Nominee. Thereafter, Silver
Lake shall notify Aprisma in writing of the identity of the Investor Aprisma
Nominee by no later than the same time shareholder proposals are due as set
forth in Aprisma's annual proxy statement filed the year preceding the year of
the applicable election of members of the Aprisma Board, which notice shall be
conclusive evidence of the consent of the initial Investor Aprisma Nominee to
serve as a director of Aprisma.  In the event Silver Lake fails to provide such
notice, the active director most recently nominated by the Investors shall be
deemed to be the Investor Aprisma Nominee.  The notice shall include all
information with respect to the Investor Aprisma Nominee as is required to be
included in a proxy statement soliciting proxies for the election of directors
pursuant to Regulation 14A under the Exchange Act.  In the event of any vacancy
on the Aprisma Board arising by reason of the Investor Aprisma Nominee's
resignation, death, removal or inability to serve, Silver Lake shall notify
Aprisma of their nominee to fill such vacancy, and, subject to clause (iii)
below, the Company shall cause Aprisma to use its reasonable best efforts to
cause the vacancy created thereby to be filled as soon as reasonably possible,
and to elect such nominee to serve until the next meeting of the stockholders
for the election of directors of Aprisma.

          (ii)  Subject to clause (iii) below, the Company shall cause Aprisma
to use its reasonable best efforts to cause the Investor Aprisma Nominee to be
included in the slate of nominees presented by the Aprisma Board to the
stockholders of Aprisma for election as directors at each relevant annual
meeting of the stockholders, and shall cause Aprisma to use its reasonable best
efforts to cause the election of the Investor Aprisma Nominee, including
soliciting proxies in favor of the election of the Investor Aprisma Nominee.
Subject to clause (iii) below, the Company shall cause Aprisma to not solicit
proxies of the stockholders of Aprisma to vote against the Investor Aprisma
Nominee or for the approval of any stockholder or other proposals that are
inconsistent with the rights afforded the Investors pursuant to this Section
5.7(b), and shall use its reasonable best efforts to oppose the removal of the
Investor Aprisma Nominee from the Aprisma Board.

                                      36
<PAGE>

          (iii)  As a condition precedent to election of any individual to fill
a vacancy as contemplated by clause (i) above and to the inclusion of any
proposed Investor Aprisma Nominee to be presented to stockholders by the Aprisma
Board pursuant to clause (ii) above, the Aprisma Board may review the
information provided pursuant to this Section 5.7(b) and such other information
as it may reasonably request in order to evaluate the Investor Aprisma Nominee's
character and fitness to serve as a director.  If the Aprisma Board reasonably
determines not to approve any Investor Aprisma Nominee, the Aprisma Board shall
inform Silver Lake of such determination, and Silver Lake shall then have the
right to nominate a substitute Investor Aprisma Nominee (and the provisions of
this Section 5.7(b) shall apply to such subsequent Investor Aprisma Nominee,
provided that any time periods provided for herein shall be shortened such that
the subsequent Investor Aprisma Nominee becomes a member of the Aprisma Board as
soon as reasonably possible).

          (c)  With respect to each Operating Subsidiary, commencing at the
later of (i) the formation of such Operating Subsidiary or (ii) the Closing, and
continuing until the consummation of a Spin-Off of such Operating Subsidiary,
Silver Lake shall have the right to designate one non-voting observer to the
Board of Directors of such Operating Subsidiary who is a member of the general
partner or investment advisor of Silver Lake; provided, however, that such right
shall not be applicable with respect to Aprisma for so long as a director
designated by Silver Lake is serving on the Aprisma Board.  Such non-voting
observers shall be entitled to participate in any meetings of such Boards of
Directors, and shall receive the same notices thereof and materials distributed
in connection therewith as are provided to the directors, and shall be provided
with visibility into, and the right to comment upon, any significant decisions
made by such Boards of Directors (including without limitation decisions with
respect to the lines of business to be pursued by each such Operating
Subsidiary, the timing and structure of its initial public offering and spin-
off, and any significant acquisitions).

          SECTION 5.8.  Transaction Fees.  (a) The Company shall pay to Silver
Lake Technology Management, L.L.C. ("SLTM") a transaction fee of $1,500,000 with
respect to the transactions contemplated hereby by wire transfer not later than

          (b) In the event that, at any time prior to the second anniversary of
the Closing, the Total Market Valuation (as defined below) exceeds
$12,000,000,000 and remains above such level as of the close of trading on ten
consecutive New York Stock Exchange (or such other primary market on which the
Company is then traded) trading days, the Company shall pay to SLTM a further
transaction fee of $2,000,000 (in addition to the transaction fees described in
Sections 5.8(a) and 5.8(c)) with respect to the transactions contemplated hereby
by wire transfer not later than the close of business on the second business day
following the end of such ten trading-day period; provided, however, that, in
the event that any Person acquires all or
<PAGE>

substantially all of the capital stock or assets of the Company prior to the
second anniversary of the Closing, the Total Market Valuation shall be measured
and become payable as of the date of the consummation of such acquisition (and
shall not thereafter be payable if not payable based upon such measurement).

          (c) In the event that, at any time prior to the second anniversary of
the Closing, the Total Market Valuation (as defined below) exceeds
$15,000,000,000 and remains above such level as of the close of trading on ten
consecutive New York Stock Exchange (or such other primary market on which the
Company is then traded) trading days, the Company shall pay to SLTM a further
additional transaction fee of $3,000,000 (in addition to the transaction fees
described in Sections 5.8(a) and 5.8(b)) with respect to the transactions
contemplated hereby by wire transfer not later than the close of business on the
second business day following the end of such ten trading-day period; provided,
however, that, in the event that any Person acquires all or substantially all of
the capital stock or assets of the Company prior to the second anniversary of
the Closing, the Total Market Valuation shall be measured and become payable as
of the date of the consummation of such acquisition (and shall not thereafter be
payable if not payable based upon such measurement).

          (d) As used in this Agreement, "Total Market Valuation" shall mean an
amount equal to the sum of (i) the Total Equity Value of the Company, (ii) the
aggregate Total Equity Values of each Operating Subsidiary that has undergone a
Spin-Off, (iii) the sum of the value at the time of distribution of all
dividends and distributions of cash, securities or other property (other than a
distribution by the Company of shares of an Operating Subsidiary in a Spin-Off,
and other than dividends or distributions to the extent paid to the Company or a
Subsidiary of the Company) paid or otherwise made after the date hereof in
respect of the capital stock of the Company, any Subsidiary of the Company or
any Operating Subsidiary that has undergone a Spin-Off and (iv) until the time
of a Spin-Off of an Operating Subsidiary, the equity value of the shares of such
Operating Subsidiary issued in its Pre-Spin-Off IPO and the shares of such
Operating Subsidiary issued to the Investors or their transferees.

          As used in this Agreement, the "Total Equity Value" for an entity at
any time means the total equity value of the entity based upon the closing
prices of the entity's shares of capital stock on The New York Stock Exchange or
on any other exchange, market or system on which such shares are then traded, in
the case of publicly traded shares of capital stock, and based on fair market
value in the case of any other shares of capital stock, provided that in the
event that any Person acquires all or substantially all of the capital stock or
assets of such entity prior to the second anniversary of the Closing, the Total
Equity Value of such entity thereafter shall be the value of the consideration
paid by such Person in such acquisition; provided, however, that in the event
that any Person (other than Silver Lake, any of its Affiliates or employees of
the Company or any of its Subsidiaries) has purchased from any such entity

                                      38
<PAGE>

following the date hereof shares of its capital stock (other than issuances in
consideration of the cancellation or exchange of outstanding shares of capital
stock of such entity), the calculation of Total Equity Value thereafter (for so
long as such shares remain outstanding) shall be reduced by the consideration
paid by such Person to such entity for such purchase.

          (d)  The limitations on indemnification obligations set forth in this

applicable Indemnitor under this Agreement shall expire; provided, however, that
such expiration shall not affect any claim with respect to which written notice
was given to an Indemnitor prior to the end of the period applicable to such
representations and warranties as set forth in Section 8.1 of this Agreement
(and such representations and warranties shall continue to survive for purposes
of any such claim).

particular Operating Subsidiary's financial statements, legal compliance, etc.),

performed prior to or after the Closing) contained in this Agreement to the
extent relating to such Operating Subsidiary (e.g., agreements relating to the

of the Callable Subsidiary Stock Purchase Rights relating to a particular
Operating Subsidiary are not required to purchase common stock pursuant to such
Callable Subsidiary Stock Purchase Rights by operation of this Section 8.6, they

the Investors to the Company, other than as set forth in this Agreement and the
other Transaction Documents to which they are parties.  This Agreement is
executed by the Company and each of the Investors freely and voluntarily, and

forth herein and in the other Transaction Documents to which they are parties.

          SECTION 9.6.  Severability.  In case any provision of this Agreement

enforceability of the remaining provisions shall not in any way be affected or
impaired thereby.

modified, and the rights of the Company or the Investors hereunder may only be
waived, upon the written consent of the Company and the Majority Investors.

omission to exercise any right, power or remedy accruing to any party, upon any
breach, default or noncompliance by another party under this Agreement or any of
the other Transaction Documents shall impair any such right, power or remedy,
nor shall it be construed to be a waiver

                                      48
<PAGE>

of any such breach, default or noncompliance, or any acquiescence therein, or of
