approval of a majority of the members of the Board of Directors.

                  (d) For so long as the Investor is entitled to designate a

shall nominate such Designee for election as a director as part of the
management slate that is included in the proxy statement (or consent
solicitation or similar document) of the Company relating to the election of
directors, and shall use commercially reasonable efforts to support the election
of such Designee and in any event efforts consistent with the Company's past and

                  (f) As long as the Investor can designate a nominee for

Shareholders; provided, however, that the foregoing provision shall not apply if
following a Change in Control of the Company the Investor does not have a

company; provided, further, that the Investor has not designated a successor
designee at the time of such shareholder vote.

                  (g) The rights of the Investor pursuant to this Section 2.1
shall terminate upon the earlier to occur of (i) the first date on which the
Restricted Parties Beneficially Own in the aggregate fewer than ___ shares
[insert number of shares of Common Stock which is 25% less than the number to be

director for all reasonable costs and expenses (including travel expenses)
incurred in connection with such director's attendance at meetings of the Board
or any committee of the Board upon which such director serves. The Company will
not pay such director annual fees and fees for attending Board or committee
meetings. The Company shall indemnify each such director to the same extent it
indemnifies its other directors pursuant to its organizational documents and
applicable law and shall purchase and maintain director liability insurance
covering the Designee to the same extent it has purchased insurance for any
director or officer in such Designee's capacity as a member of the Board of

                           (ix)     solicit, initiate, encourage or knowingly
or intentionally facilitate the taking of any action by any Affiliate of a

plan or arrangement  inconsistent with the foregoing.

                  (b) In addition, during the Standstill Period (and only during
the Standstill Period), no Restricted Party will, nor will they authorize or
permit any of their respective Representatives to, take any action that could
require the Company to make a public announcement regarding any of the matters
set forth in Section 3.1(a).

                  (c) If, at any time during the Standstill Period, (i) any

not been rejected by the Board of Directors, (ii) the Board of Directors has
determined to pursue a Takeover Transaction or other Change in Control of the

Board of Directors or the Company has engaged in any discussions or negotiations
with, or provided any information to, any Person other than a Restricted Party
or any Affiliate thereof or any 13D Group of which any Restricted Party is a
member with respect to a potential Takeover Transaction or other Change in
Control of the Company or any potential inquiry, proposal or offer relating
thereto and the Board of Directors has not resolved to terminate all such
discussions, negotiations and provision of information, then, for so long as
such condition continues to apply, notwithstanding the limitation in clause (a)
above, a Restricted Party may make an offer or proposal relating to a Takeover
Transaction or other Change in Control of the Company directed privately to the
Company (but all other provisions of this Agreement will, subject to Section
3.1(d), continue to apply). Notwithstanding the foregoing provisions, if at any
time during the Standstill Period, any Person other than a Restricted Party has
entered into a confidentiality agreement or equivalent agreement containing
standstill provisions, then the Company shall promptly provide (but in any case
within 48 hours of entering into such agreement) notice of such standstill
provisions to the Investor, and the Investor (acting on behalf of each of the
Restricted Parties) shall have the option, exercisable upon delivery of notice
to the Company within 48 hours of receipt of the notice from the Company, to be
bound during the term of such other Person's standstill provisions by either the
provisions regarding standstill in such other Person's agreement or the
provisions of Section 3.1(a) with respect to any Restricted Party's actions in
regard to a proposed Takeover Transaction or other Change in Control of the
Company by such Restricted Party. In the event any other Person receives
non-public information in regard to a proposed Takeover Transaction or other
Change in Control of the Company without standstill restrictions, then the
Company shall promptly provide (but in any case within 48 hours of receiving
such information) notice of such fact to the Investor and provisions of this
Section 3.1 shall not apply to the Restricted Parties.

                  (d) Anything in this Section 3.1 to the contrary
notwithstanding, this Section 3.1 shall not prohibit or restrict any of the
following: (x) actions taken by the Investor's nominees on the Board of
Directors in such capacity, (y) the exercise by the Restricted Parties of their
voting rights (i.e., their right to vote their shares but not their right to
make nominations, to the extent prohibited by this Agreement), with respect to
any shares of Voting Stock they Beneficially Own and (z) any disclosure pursuant
to Section 13(d) of the Exchange Act which a Restricted Party reasonably
believes, based on the advice of outside counsel, is required in connection with
any action taken by a Restricted Party pursuant to Section 3.1(c).

         Section 3.2.      Transfer Restrictions.

                  (a) The Restricted Parties shall not, directly or indirectly
sell, transfer or otherwise dispose of (collectively, "Transfer") any shares of
Common Stock Beneficially Owned by such Persons or any legal or beneficial
interest therein during the period ending on the one year anniversary of the
date of this Agreement, except for Transfers: (i) to Restricted Parties who
agree to be Restricted Parties bound by the provisions of this Agreement in a
written instrument delivered to the Company in form and substance reasonably
satisfactory to the Company, (ii) which have been consented to in writing by the
Company, (iii) pursuant to a Third Party Tender Offer that is




                                      -7-
<PAGE>   9

recommended by the Board of Directors, (iv) pursuant to a merger, consolidation
or reorganization to which the Company is a party or (v) pursuant to bona fide
hedging transactions with or arranged by nationally recognized investment
banking firms or other nationally recognized financial institutions provided
that the total number of shares which may underlie all such hedging transactions
entered into or renewed during this one year period shall be limited, as if such
hedging transaction were treated as a Transfer subject to the volume limitations
of Rule 144 of the Securities Act, to 50% of the total volume limitation under
Rule 144 at the time of such calculation. However, if any Restricted Party has
any hedge transaction or transactions in place, then such Restricted Party shall
be allowed to renew, amend or extend any such hedge transactions, whether or not
such hedge transactions exceed the other limits provided in this Section 3.2, so
long as the aggregate number of shares underlying all hedge transactions of the
Restricted Parties after such renewal, amendment or extension does not exceed
the aggregate number of shares underlying all hedge transactions of the
Restricted Parties immediately before such renewal, amendment or extension;
provided, however, that such hedge transaction or transactions shall have been
in compliance with this Section 3.2 at the time such transaction or transactions
was or were initially entered into by such Restricted Party (without limiting
any subsequent renewals, amendments or extensions). During the period commencing
on the Effective Date and concluding on the one year anniversary of the
Effective Date, the Restricted Parties agree not to enter into, renew or amend
more than one hedge transaction during any calendar quarter if such entry,
renewal or amendment would require the filing of an amendment to any Schedule
13D filed by any Restricted Party to report the details of such hedge
transaction.

                  (b) Unless the Restricted Parties Beneficially Own in the
aggregate less than 5% of the Outstanding Common Stock, during the period
beginning on the one year anniversary of the date of this Agreement and ending
on the three year anniversary of the date of this Agreement, the Restricted
Parties shall not, directly or indirectly, Transfer any of the shares of Common
Stock Beneficially Owned by such Persons or any legal or beneficial interest
therein, except for Transfers: (i) permitted pursuant to Section 3.2(a)(i),
(ii), (iii), (iv) and (v); (ii) in a bona fide public distribution or bona fide
underwritten public offering (including pursuant to the exercise of rights
granted in the Registration Rights Agreement); or (iii) of shares in an amount
equal to the number of shares of such Common Stock that could be sold under the
volume limitations of Rule 144 of the Securities Act during any applicable
period under Rule 144; provided, however, that shares underlying any hedging
transaction shall be included in calculating such volume limitation; and
provided further that, (A) in the case of any Transfer pursuant to clause (ii)
or (iii),except as permitted by Section 3.2(c), such Transfer does not result
in, to the knowledge of the Restricted Parties, any other Person acquiring,
after giving effect to such Transfer, Beneficial Ownership, individually or in
the aggregate with such Person's Ultimate Parent Entity, Subsidiaries and
Affiliates, of more than 5% of the Outstanding Common Stock, and (B) any hedging
transaction may be with respect to 100% of the total volume limitation which
would apply under Rule 144 at the time of such calculation as set forth in
Section 3.2(a)(v). In regard to any Transfer pursuant to clause (ii) of this
Section 3.2(b), Restricted Parties shall provide that any underwriting or
placement agreement provide that the underwriter or placement agent arrange for
such sales such that the amount of Common Stock that any Person would acquire
thereunder would not result in, after giving effect to such Transfer, to the
knowledge of such agent, Beneficial Ownership, individually or in the aggregate
with such Person's Ultimate Parent Entity, Subsidiaries or Affiliates, of more
than 5% of the Outstanding Common Stock. In regard to any Transfer pursuant to
clause (iii) of this Section 3.2(b), Restricted Parties shall provide that their
brokers observe the restrictions in the preceding sentence in face-to-face
transactions; however, such restrictions shall not be applicable to open market
transactions.

                  (c) Any Restricted Party may Transfer shares of Common Stock
pursuant to clauses (ii) or (iii) of Section 3.2(b) which would constitute more
than 5% of the outstanding Common Stock or a number of shares to a Person such
that after giving effect to such Transfer the Restricted Parties know that such
Person would have Beneficial Ownership of more than 5% of the Outstanding Common
Stock only if (1) such Person receiving such shares of Common Stock is eligible
to file a Schedule 13G pursuant to Rule 13d-1(b) and (2) prior to any such
Transfer, such Restricted Party, at least 2 business days prior to making any
such Transfer, offers to sell such shares to the Company by sending written
notice (the "Offering Notice") to the Company, which Offering Notice shall state
(i) the number of shares proposed to be Transferred (the "Offered Securities"),
(ii) the proposed purchase price per share which such Restricted Party is
willing to accept (the "Offer Price"), and (iii) to the extent known, the other
terms and conditions of such Transfer, including the identity of any proposed
transferee. Upon delivery of the Offering Notice, such offer shall be
irrevocable unless and until the rights of first offer provided for herein shall



                                      -8-
<PAGE>   10


have been waived in writing by the Company or shall have otherwise expired in
accordance with the terms hereof. For a period of 2 business days after receipt
of the Offering Notice, the Company shall have the option to purchase all of the
Offered Securities at a purchase price equal to the Offer Price and upon the
terms and conditions set forth in the Offering Notice by providing notice to
such Restricted Party of the exercise of such option prior to the expiration of
such 2 business day period. If the Company fails to elect to exercise such
option for all of the Offered Securities within 2 business days after its
receipt of the Offering Notice, such Restricted Party may Transfer the Offered
Securities subject to the terms of Section 3.2(b) and on terms that are no more
favorable to the transferee thereof than those specified in the Offering Notice,
except with respect to the Offer Price, which shall not be less than 95% of the
Offer Price indicated in the Offering Notice; provided that any such Transfer by
such Restricted Party to a transferee must be consummated during the 45-day
period immediately subsequent to the expiration of the 2 business day period
after the Company receives the Offering Notice. If such Transfer (A) is not
consummated within such 45-day period for any reason or (B) is on terms that are
more favorable to the transferee thereof than those specified in the Offering
Notice (including but not limited to an Offer Price that is less than 95% of the
Offer Price indicated in the Offering Notice), then in each case the
restrictions provided for herein shall again become effective, and no Transfer
of such Offered Securities may be made thereafter by such Restricted Party
without again offering the same to the Company in accordance with this Section
3.2(c).

                  (d) If any Restricted Party decides to dispose of any of the
Common Stock, each Restricted Party understands and agrees that it may do so
only pursuant to an effective registration statement under the Securities Act or
pursuant to an exemption from registration under the Securities Act. Each
Restricted Party agrees to the imprinting, so long as appropriate, of
substantially the following legends on certificates representing any of the
securities referenced in the preceding sentence:

         THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
         UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES
         ACT"), OR ANY STATE SECURITIES LAW, AND SUCH SECURITIES MAY NOT BE
         OFFERED, SOLD, TRANSFERRED OR OTHERWISE DISPOSED OF EXCEPT PURSUANT TO
         AN EFFECTIVE REGISTRATION STATEMENT OR PURSUANT TO AN EXEMPTION FROM,
         OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF
         THE SECURITIES ACT AND APPLICABLE STATE SECURITIES LAWS. THE SECURITIES
         REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO THE TERMS OF A
         STOCKHOLDER AGREEMENT, DATED AS OF ____________ __, 2000, AMONG THE
         COMPANY AND [MICROSOFT][FDC].

         The legend set forth above shall be removed if and when (i) the
securities represented by such certificate are disposed of pursuant to an
effective registration statement under the Securities Act or (ii) the Investor
delivers to the Company an opinion of counsel reasonably acceptable to the
Company to the effect that such legends are no longer necessary.

                  (e) This Section 3.2 shall terminate upon the earlier to occur
of the following: (i) the third anniversary of the date of this Agreement, (ii)
any Change in Control of the Company, or (iii) a reduction in the Restricted
Parties' aggregate Beneficial Ownership to less than 5% of the Total Current
Voting Power of all outstanding Voting Stock of the Company.

         Section 3.3 Certain Permitted Transactions and Communications.
Notwithstanding the foregoing, this Agreement shall not prohibit (i) the
acquisition or holding of securities or rights in the ordinary course of
business by any employee benefit plan whose trustees, investment managers or
similar advisors are not Affiliates of any Restricted Party, (ii) the
consummation of any transaction expressly provided for in the Merger Agreement
or (iii) officers and employees of the Restricted Parties from communicating
with officers of the Company or its Affiliates on matters related to or governed
by the Merger Agreement or other operational matters, or the Restricted Parties
from communicating with the Board of Directors, the Chairman of the Board of
Directors, the Chief Executive Officer or the Chief Financial Officer of the
Company, so long as such communication is conveyed in confidence, could not
require public disclosure by the Restricted Parties or by the Company, and is
not intended to (a) elicit, and, in the reasonable belief (based on the advice
of outside counsel) of the Restricted Party making such

                                      -9-

communication, does not require the issuance of, a public response by the
Company or (b) otherwise circumvent the provisions of Section 3.2.

                                RIGHTS AGREEMENT

         Section 4.1 HoldCo Rights Agreement. So long as [Microsoft][FDC]
Beneficially Own 5% or more of the Outstanding Common Stock, (i) the Company
shall not amend the HoldCo Rights Plan (as defined in the Merger Agreement) to
adversely affect [Microsoft][FDC] under such HoldCo Rights Plan and (ii) to the
extent that the Company waives application of such HoldCo Rights Plan for any
other Person the Company shall give the same waiver to [Microsoft][FDC];
provided that this Section 4.1 shall not apply with respect to the actions or
amendments to the HoldCo Rights Plan necessary to implement a transaction
approved by the Board of Directors of the Company.

notices shall be effective when received.

         Section 5.2 Entire Agreement; Amendment. This Agreement sets forth the
entire agreement between the parties hereto with respect to the matters subject
to this Agreement. Any provision of this Agreement may be amended or modified in
whole or in part at any time by an agreement in writing between the parties
hereto executed in the same manner as this Agreement. No failure on the part of
any party to exercise, and no delay in exercising, any right shall operate as a
waiver thereof nor shall any single or partial exercise by any party of any
right preclude any other or future exercise thereof or the exercise of any other
right.

         Section 5.3 Severability. In the event that any one or more of the
provisions contained in this Agreement or in any other instrument referred to
herein, shall, for any reason, be held to be invalid, illegal or unenforceable
in any respect, such invalidity, illegality or unenforceability shall not affect
any other provision of this Agreement or any other such instrument.

         Section 5.4 Counterparts. This Agreement may be executed in one or more
counterparts, each of which shall be deemed to constitute an original, but all
of which together shall constitute one and the same document.

         Section 5.5 Governing Law; Jurisdiction; Waiver of Jury Trial. This
Agreement shall be governed and construed in accordance with the laws of the
State of Delaware applicable to contracts executed and performed entirely within
such state, and each party hereby submits to the non-exclusive jurisdiction of
any state or U.S. federal court sitting within the State of Delaware. The
parties hereto waive all right to trial by jury in any action, suit or
proceeding brought to enforce or defend any rights or remedies under this
Agreement.

         Section 5.6 Successors and Assigns; Third Party Beneficiaries. The
Investor and any other Restricted Party that agrees to be bound by the terms
hereof may not assign any of its rights or delegate any of its duties under this
Agreement. The Company may not assign any of its rights or delegate any of its
duties under this Agreement without the prior written consent of the Investor,
provided that in the event of any merger or consolidation of the




                                      -11-
<PAGE>   13

Company with any Person in which the holders of Common Stock receive securities
of any other Person (the "Successor Issuer") the Company may assign all of its
rights and delegate all of its obligations under this Agreement to such
Successor Issuer in which event the Successor Issuer will become the "Company"
for all purposes of this Agreement (except with respect to Section 2.1(g) if
such merger or consolidation involves a Change in Control, in which case the
restrictions on the Restricted Parties shall terminate). Any purported
assignment in violation of this Section shall be void. Nothing expressed or
mentioned in this Agreement is intended or shall be construed to give any Person
other than the Restricted Parties (who shall be third party beneficiaries of
this Agreement entitled to the benefit of, and to enforce, its terms) and the
Company and their respective successors, any legal or equitable right, remedy or
claim under or in respect of this Agreement or any provision herein contained.
This Agreement and all conditions and provisions hereof are intended to be for
the sole and exclusive benefit of the Restricted Parties and the Company and
their respective successors, and for the benefit of no other Person. No
purchaser of Common Stock from a Restricted Party (other than another Restricted
Party) shall be deemed to be a successor or assignee by reason merely of such
purchase.

         Section 5.7 Specific Performance. The parties hereto agree that
irreparable damage would occur in the event any provision of this Agreement was
not performed in accordance with the terms hereof and that the parties shall be
entitled to an injunction or injunctions to prevent breaches of this Agreement
and to enforce specifically the terms and provisions of this Agreement in
addition to any other remedy to which they are entitled at law or in equity.

         Section 5.8 Headings, Captions and Table of Contents. The Section
headings, captions and table of contents contained in this Agreement are for
reference purposes only, are not part of this Agreement and shall not affect the
meaning or interpretation of this Agreement.

         Section 5.9 Confidentiality. The confidentiality agreement dated
November 2, 1999 between the Company and the Investor (the "Investor
Confidentiality Agreement") shall, except for Sections 4(f) and 4(g) thereof
which provisions are hereby terminated, continue and be in full force and effect
and apply to each Restricted Party as if it were the Investor until the earlier
of (i) the termination of the Investor's rights to designate a director for
nomination to the Board of Directors of the Company pursuant to Section 2.1 or
(ii) the absence of a Designee on the Board of Directors.

         Section 5.10 No Adverse Actions. The Company will not adopt any
amendment to its certificate of incorporation, bylaws or rights agreement or
enter into or adopt any plans, agreements, arrangements or understandings which
have the effect of materially impeding, preventing or prohibiting the Restricted
Parties' aggregate Beneficial Ownership of shares of Voting Stock to be equal to
or less than the Standstill Limit.
