INTRODUCTION

         No shares of common stock, par value $.001 per share (the "Common
Stock"), of The Vincam Group, Inc., a Florida corporation (the "Issuer"), have
been purchased, directly or indirectly, by the reporting person. Automatic Data
Processing, Inc., a Delaware corporation ("ADP"), is making this filing solely
because it may be deemed to have beneficial ownership of the shares reported
herein pursuant to the Voting Agreement (as defined below).

         On December 3, 1998, the Issuer, ADP and ADP Acquisition Corp.
(Florida), a Florida corporation and wholly owned subsidiary of ADP ("Sub"),
entered into an Agreement and Plan of Merger, in the form attached hereto as
Exhibit 1 (the "Merger Agreement"), which is incorporated herein by reference.
Under the terms of the Merger Agreement, Sub will be merged with and into the
Issuer (the "Merger"), and in connection therewith each outstanding share of
Common Stock will be exchanged for .229 shares of common stock, par value $.10
per share (the "ADP Common Stock"), of ADP, provided that the average price of
ADP Common Stock for the 10 trading days ending three business days prior to the
shareholders meeting to be held to approve the Merger Agreement is between
$68.781 and $84.065. For average prices of ADP Common Stock of between $61.138
and $68.781, the exchange ratio adjusts to keep the value constant at $15.25 per
share of Common Stock. Similarly, between $84.065 and $91.708, the exchange
ratio adjusts to keep the value constant at $19.25 per share of Common Stock.
Above $91.708, the exchange ratio remains fixed at .2099 shares of ADP Common
Stock for each share of Common Stock. Should the average price of ADP Common
Stock fall below $61.138, the Issuer has the option to accept an exchange ratio
of .2576 shares of ADP Common Stock for each share of Common Stock or it may
request that ADP issue additional shares of ADP Common Stock to keep the value
constant at $15.75. If ADP does not issue additional shares, the Issuer can
terminate the agreement. The exchange ratios described above are subject to
certain additional adjustments set forth in the Merger Agreement.

         Completion of the Merger is subject to the satisfaction of a number of
conditions, including the approval of the Merger Agreement by the holders of
shares of Common Stock of the Issuer. In connection therewith, ADP and certain
shareholders of the Issuer (each a "Shareholder" and, collectively, the
"Shareholders") have entered into a Voting Agreement, dated as of December 3,
1998, in the form attached hereto as Exhibit 2 (the "Voting Agreement"), which
is incorporated herein by reference, whereby each Shareholder has agreed that,
at any meeting of the shareholders of the Issuer, however called, and in any
action by consent of the shareholders of the Issuer, such Shareholder will vote
(or cause to be voted) the shares of Common Stock held of record (to the extent
such person also has the right to vote such shares) or beneficially owned (to
the extent such person also has the right to vote such shares) by such
Shareholder in favor of the Merger, the Merger Agreement (as amended from time
to time) and the transactions contemplated by the Merger Agreement.

         Each Shareholder further agreed that, (i) such Shareholder will not, or
permit any person under such Shareholder's control to, enter into any voting
agreement or grant a proxy or power of attorney with respect to the shares of
Common Stock held of record or beneficially owned by such Shareholder or form
any "group" for purposes of the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), or the rules promulgated thereunder, in each such case, which
is inconsistent with the Voting Agreement, and (ii) except as set forth in the
Merger Agreement, such Shareholder will not (x) solicit, initiate, encourage
(including by way of furnishing information or assistance) or take any other
action to facilitate, any inquiry or the making of any proposal which
constitutes, or may reasonably be expected to lead to, any Transaction Proposals
(as defined in the Merger Agreement) or agree to or endorse any Transaction
Proposal or (y) propose, enter into or participate in any discussions or

                                  Page 3 of 12
<PAGE>

negotiations regarding any of the foregoing, or furnish to any other person any
information with respect to its business, properties or assets or any of the
foregoing, or otherwise cooperate in any way with, or assist or participate in,
facilitate or encourage, any effort or attempt by any other person to do or seek
any of the foregoing.

         Each Shareholder further agreed that, except as set forth in the Voting
Agreement, such Shareholder will not (i) tender any shares of Common Stock, (ii)
sell, assign or transfer record or beneficial ownership of any of the shares of
Common Stock, or (iii) further pledge, hypothecate or otherwise dispose of any
shares of Common Stock.

         The Voting Agreement terminates upon the earlier to occur of (i) the
closing of the transactions contemplated by the Merger Agreement and (ii) the
date the Merger Agreement is terminated in accordance with its terms.

         Under the terms of the Voting Agreement, if a Shareholder acquires the
right to vote any additional shares of Common Stock, the Voting Agreement shall
be applicable to such additional shares.

         ADP has agreed, prior to the closing of the transactions contemplated
by the Merger Agreement, to enter into a registration rights agreement with the
Shareholders and, as contemplated thereby, to (i) file promptly after the
registration statement relating to the shares of ADP Common Stock to be issued
in connection with the Merger is declared effective and (ii) use its reasonable
commercial efforts to have declared effective by the SEC on or prior to
effective time of the Merger a registration statement on Form S-3 covering the
shares of ADP Common Stock to be received by the Shareholders in the Merger in
exchange for their shares of Common Stock of the Issuer and use its reasonable
commercial efforts to maintain the effectiveness of such registration statement
until the earlier of (x) the date all such shares are disposed of and (y) one
year from the date of effectiveness.

         The description of the transactions summarized above are qualified in
their entirety by reference to the Exhibits attached hereto.

ITEM 1.  SECURITY AND ISSUER.

         The class of equity securities to which this Statement on Schedule 13D
(the "Statement") relates is the common stock, par value $.001 per share
(defined above as the "Common Stock"), of The Vincam Group, Inc., a Florida
corporation (defined above as the "Issuer"). The principal executive offices of
the Issuer are located at 10200 Sunset Drive, Miami, Florida 33173.

ITEM 2.  IDENTITY AND BACKGROUND.

         (a)-(c), (f). This Statement is filed by Automatic Data Processing,
Inc., a Delaware corporation (defined above as "ADP"). The principal business of
ADP is computing services. The address of the principal business and principal
office of ADP is One ADP Boulevard, Roseland, New Jersey 07068.

         The name, residence or business address, present principal occupation
or employment and the name, principal business and address of any corporation or
other organization in which such employment is conducted and citizenship of each
executive officer and director of ADP are set forth in Schedule 1 hereto, which
is incorporated herein by reference.

<PAGE>

         (d) During the last five years, neither ADP nor, to the best of its
knowledge, any of the persons listed on Schedule 1 hereto has been convicted in
a criminal proceeding (excluding traffic violations or similar misdemeanors).

         (e) During the last five years, neither ADP nor, to the best of its
knowledge, any of the persons listed on Schedule 1 hereto has been a party to a

and as a result of such proceeding was or is subject to a judgment, decree or
final order enjoining future violations of, or prohibiting or mandating
activities subject to, federal or state securities laws or finding any violation
with respect to such laws.

ITEM 3.  SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

         No shares of the Issuer's Common Stock have been purchased, directly or
indirectly, by ADP. Rather, as an inducement and a condition to its entering
into the Merger Agreement, ADP and the Shareholders have entered into the Voting
Agreement, pursuant to which the Shareholders have agreed to vote their
respective shares of Common Stock in favor of the Merger Agreement (as more
fully described in the Introduction of this Statement, which is incorporated by
reference herein).

ITEM 4.  PURPOSE OF TRANSACTION.

         No shares of the Issuer's Common Stock have been purchased, directly or
indirectly, by ADP. ADP could be deemed to have "acquired" beneficial ownership
of the shares of Common Stock to which this Statement relates only in the sense
that it and the Shareholders have entered into the Voting Agreement (as
described in the Introduction of this Statement, which is incorporated by
reference herein) in order to facilitate the Merger pursuant to the Merger
Agreement. Except as specifically set forth herein, ADP disclaims beneficial
ownership over any shares of the Common Stock, including the power to vote, to
direct the voting of, to dispose, or to direct the disposition of, any shares of
the Common Stock.

         Each of Paragraphs (a) through (j) of Item 4 may be applicable to the
transactions contemplated by the Merger Agreement.


ITEM 5.  INTEREST IN SECURITIES OF THE ISSUER.

         (a) ADP may be deemed to beneficially own 7,084,906 shares of Common
Stock as a result of entering into the Voting Agreement, which, based on
calculations made in accordance with Rule 13d-3 promulgated under the Exchange
Act and there being 15,733,031 shares of Common Stock outstanding on December 3,
1998 (as represented to ADP by the Issuer in the Merger Agreement), represents
approximately 45% of the outstanding Common Stock. To the knowledge of ADP, none
of the persons identified in Schedule 1 beneficially owns any securities of the
Issuer. Except as specifically set forth herein, ADP disclaims beneficial
ownership over any shares of the Common Stock, including the power to vote, to
direct the voting of, to dispose, or to direct the disposition of, any shares of
the Common Stock. ADP disclaims membership in any group with respect to the
Common Stock, by virtue of ADP's execution of the Voting Agreement or otherwise.

         (b) As a result of entering into the Voting Agreement, ADP may be
deemed to have shared power to vote or to direct the vote of the shares of
Common Stock herein reported as beneficially owned by it.

                                   ARTICLE II

                EFFECT OF THE MERGER ON THE CAPITAL STOCK OF THE
               CONSTITUENT CORPORATIONS; EXCHANGE OF CERTIFICATES

         2.1 Effect on Capital Stock. As of the Effective Time, by virtue of the
Merger and without any action on the part of the holder of any shares of VCAM
Common Stock or capital stock of Sub:

                  (a) Capital Stock of Sub. Each share of common stock, par
value $.01 per share ("Sub Common Stock"), of Sub issued and outstanding
immediately prior to the Effective time shall be converted into and become one
share of common stock of the Surviving Corporation with the same rights, powers
and privileges as the shares so converted and shall constitute the only
outstanding shares of capital stock of the Surviving Corporation;

                  (b) Exchange Ratio for VCAM Common Stock. Each share of VCAM
Common Stock issued and outstanding immediately prior to the Effective Time
shall, except as otherwise provided in Section 2.2, be converted by virtue of
the Merger and without any action on the part of the holder thereof into and
exchangeable for the right to receive a number of fully paid and non-assessable
shares of common stock, par value $.10 per share (the "ADP Common Stock"), of
ADP equal to the "Exchange Ratio," determined in the manner set forth below:

                           (i) If the Average ADP Stock Price is equal to or
greater than $68.781 and less than or equal to $84.065, then the Exchange Ratio
shall be .229; provided, that, if the Outstanding Diluted VCAM Stock Amount
exceeds 16,190,804, then the Exchange Ratio shall equal the quotient (rounded to
four decimal points) obtained by dividing (x) 3,707,694 by (y) the Outstanding
Diluted VCAM Stock Amount;

                           (ii) If the Average ADP Stock Price is equal to or
greater than $61.138 and less than $68.781, then the "Exchange Ratio" shall be
equal to the quotient (rounded to four decimal points) obtained by dividing
15.75 by the Average ADP Stock Price; provided, that if the Outstanding Diluted
VCAM Stock Amount exceeds 16,190,804, then the Exchange Ratio shall be equal to
the quotient (rounded to four decimal points) obtained by dividing (x) the
quotient obtained by dividing (1) $255,018,909 by (2) the Average ADP Stock
Price by (y) the Outstanding Diluted VCAM Stock Amount;
<PAGE>

                                                                               4

                           (iii) If the Average ADP Stock Price is greater than
$84.065 and less than or equal to $91.708, then the "Exchange Ratio" shall be
equal to the quotient (rounded to four decimal points) obtained by dividing
19.25 by the Average ADP Stock Price; provided, that if the Outstanding Diluted
VCAM Stock Amount exceeds 16,190,804, then the Exchange Ratio shall be equal to
the quotient (rounded to four decimal points) obtained by dividing (x) the
quotient obtained by dividing (1) $311,687,306 by (2) the Average ADP Stock
Price by (y) the Outstanding Diluted VCAM Stock Amount;

                           (iv) If the Average ADP Stock Price is greater than
$91.708, then the "Exchange Ratio" shall be .2099; provided, that if the
Outstanding Diluted VCAM Stock Amount exceeds 16,190,804, then the Exchange
Ratio shall be equal to the quotient (rounded to four decimal points) obtained
by dividing (x) 3,398,693 by (y) the Outstanding Diluted VCAM Stock Amount;

                           (v) If the Average ADP Stock Price is less than
$61.138, then the "Exchange Ratio" shall be .2576; provided, that if the
Outstanding Diluted VCAM Stock Amount exceeds 16,190,804, then the Exchange
Ratio shall be equal to the quotient obtained by dividing (x) 4,171,201 by (y)
the Outstanding Diluted VCAM Stock Amount; provided, further, that VCAM shall
have the right to give written notice to ADP (the "Top-Up Request Notice")
requesting that the Exchange Ratio be increased to equal to the quotient
(rounded to four decimal points) obtained by dividing (x) the quotient obtained
by dividing (1) $255,018,909 by (2) the Average ADP Stock Price by (y) the
Outstanding Diluted VCAM Stock Amount (the "Topped-Up Exchange Ratio"). The
Top-Up Request Notice shall be delivered to and received by ADP no later than
2:00 p.m. on the second Business Day prior to the Stockholders' Meeting. ADP,
may, in its sole discretion, agree or not agree to increase the Exchange Ratio
to the Topped-Up Exchange Ratio. Within 24 hours of receiving the Top-Up Request
Notice, ADP shall provide VCAM written notice of its determination with respect
thereto. If ADP agrees to increase the Exchange Ratio to the Topped-Up Exchange
Ratio, the Exchange Ratio shall be equal to the Topped-Up Exchange Ratio for
purposes of this Agreement. If ADP does not agree in its sole discretion that
the Exchange Ratio shall be increased to be the Topped-Up Exchange Ratio (which
disagreement shall be deemed to have occurred if ADP does not respond to the
Top-Up Request Notice within the 24 hour period specified above), VCAM shall
either (x) agree that the Exchange Ratio shall be as determined pursuant to the
first sentence of this Section 2.1(b)(v) without giving effect to the proviso to
such sentence or (y) give written notice (the "Termination Notice") that VCAM
elects to terminate this Agreement. The Termination Notice shall be delivered to
ADP no later than 5:00 p.m. on the Business Day prior to the Stockholders'
Meeting; provided, that if the Termination Notice has not been received by ADP
by such time, VCAM shall be deemed to have accepted the Exchange Ratio as
determined pursuant to the first sentence of this Section 2.1(b)(v) without
giving effect to the proviso to such sentence and VCAM shall have no further
right to terminate this Agreement pursuant to this Section 2.1(b)(v) or Section
7.1(e);
<PAGE>

                                                                               5

                           (vi) If, between the date of this Agreement and the
Effective Time, the outstanding shares of VCAM Common Stock or ADP Common Stock
are changed into a different number or class of shares by reason of any stock
split, division or subdivision of shares, stock dividend, reverse stock split,
consolidation of shares, reclassification, recapitalization or other similar
transaction, then the provisions of this Section 2.1(b) shall be appropriately
adjusted; and

                  (c) Cancellation of Treasury Stock and ADP-Owned Stock. Each
outstanding share of VCAM Common Stock, held by VCAM as treasury stock or owned
by ADP or any Subsidiary of ADP immediately prior to the Effective Time shall be
canceled, and no payment shall be made with respect thereto.

         2.2 Exchange of Certificates.

                  (a) Exchange Agent. As of the Effective Time, ADP shall
deposit with Chase Mellon Shareholder Services or such other bank or trust
company designated by ADP (and reasonably acceptable to VCAM) (the "Exchange
Agent"), for the benefit of the holders of shares of VCAM Common Stock, for
exchange in accordance with this Article II, through the Exchange Agent,
certificates representing the shares of ADP Common Stock (such shares of ADP
Common Stock, together with any dividends or distributions with respect thereto,
being hereinafter referred to as the "Exchange Fund") issuable pursuant to
Section 2.1 in exchange for outstanding shares of VCAM Common Stock. For this
purpose, the number of shares of ADP Common Stock issuable under Section 2.1
shall mean the product of (i) the Exchange Ratio multiplied by (ii) the number
of outstanding shares of VCAM Common Stock as of the Effective Time, rounded up
to the nearest whole number.

                  (b) Exchange Procedures. As soon as reasonably practicable
after the Effective Time, ADP shall instruct the Exchange Agent to mail to each
holder of record of a certificate or certificates which immediately prior to the
Effective Time represented outstanding shares of VCAM Common Stock (the
"Certificates") whose shares were converted into the right to receive shares of
ADP Common Stock pursuant to Section 2.1, (i) a letter of transmittal (which
shall specify that delivery shall be effected, and risk of loss and title to the
Certificates shall pass, only upon delivery of the Certificates to the Exchange
Agent and shall be in such form and have such other provisions as are usual and
customary as ADP may reasonably specify) and (ii) instructions for use in
effecting the surrender of the Certificates in exchange for certificates
representing shares of ADP Common Stock. Upon surrender of a Certificate for
cancellation to the Exchange Agent or to such other agent or agents as may be
appointed by ADP, together with such letter of transmittal and such other
customary documents as may be required pursuant to such instructions, duly
executed, the holder of such Certificate shall be entitled to receive in
exchange therefor a certificate representing that number of whole shares of ADP
Common Stock and cash in lieu of any fractional share of ADP Common Stock, plus
any dividends, which such holder has the right to receive pursuant to the
provisions of
<PAGE>

                                                                               6

this Article II, and the Certificate so surrendered shall forthwith be canceled.
In the event of a transfer of ownership of VCAM Common Stock which is not
registered in the transfer records of VCAM, a certificate representing the
proper number of shares of ADP Common Stock may be issued to a transferee if the
Certificate representing such VCAM Common Stock is presented to the Exchange
Agent, accompanied by all documents required to evidence and effect such
transfer and by evidence that any applicable stock transfer taxes have been
paid. Until surrendered as contemplated by this Section 2.2, each Certificate
shall be deemed at any time after the Effective Time to represent only the right
to receive upon such surrender the certificate representing shares of ADP Common
Stock and cash in lieu of any fractional shares of ADP Common Stock as
contemplated by Section 2.2(e). Subject to the effect of applicable laws,
following surrender of any such Certificate, there shall be paid to the record
holder of the certificates representing whole shares of ADP Common Stock issued
in exchange therefor, without interest, (x) at the time of such surrender (or as
soon thereafter as the cash from the sale of the Excess Shares referred to in
Section 2.2(e) is obtained by the Exchange Agent), the amount of any cash
payable in lieu of a fractional share of ADP Common Stock to which such holder
is entitled pursuant to Section 2.2(e), (y) at the time of such surrender, the
amount of dividends or other distributions with a record date after the
Effective Time theretofore paid with respect to such whole shares of ADP Common
Stock and (z) at the appropriate payment date, the amount of dividends or other
distributions with a record date after the Effective Time but prior to surrender
and a payment date subsequent to surrender payable with respect to such whole
shares of ADP Common Stock.

                  (c) Distributions with Respect to Unexchanged Shares. No
dividends or other distributions declared or made after the Effective Time with
respect to ADP Common Stock with a record date after the Effective Time shall be
paid to the holder of any unsurrendered Certificate with respect to the shares
of ADP Common Stock represented thereby and no cash payment in lieu of
fractional shares shall be paid to any such holder pursuant to Section 2.2(e)
until the holder of record of such Certificate shall surrender such Certificate.

                  (d) No Further Ownership Rights in VCAM Common Stock. All
shares of ADP Common Stock issued upon the surrender for exchange of shares of
VCAM Common Stock in accordance with the terms hereof (including any cash paid
pursuant to Section 2.2(c) or 2.2(e)) shall be deemed to have been issued in
full satisfaction of all rights pertaining to such shares of VCAM Common Stock,
and there shall be no further registration of transfers on the stock transfer
books of the Surviving Corporation of the shares of VCAM Common Stock which were
outstanding immediately prior to the Effective Time. If, after the Effective
Time, Certificates are presented to the Surviving Corporation for any reason,
they shall be canceled and exchanged as provided in this Article II.

                                                                               7

                  (e) No Fractional Shares.

                           (i) No certificates or scrip representing fractional
shares of ADP Common Stock shall be issued upon the surrender for exchange of
Certificates, and such fractional share interests will not entitle the owner
thereof to vote or to any rights of a stockholder of ADP.

                           (ii) As promptly as practicable following the
Effective Time, the Exchange Agent shall determine the excess of (x) the number
of full shares of ADP Common Stock in the Exchange Fund over (y) the aggregate
number of full shares of ADP Common Stock to be distributed to holders of VCAM
Common Stock pursuant to Section 2.2(b) (such excess being herein called the
"Excess Shares"). As soon after the Effective Time as practicable, the Exchange
Agent, as agent for the holders of VCAM Common Stock, shall sell the Excess
Shares at then prevailing prices on the NYSE, all in the manner provided in
paragraph (iii) of this Section.

                           (iii) The sale of the Excess Shares by the Exchange
Agent shall be executed on the NYSE through one or more member firms of the NYSE
and shall be executed in round lots to the extent practicable. Until the net
proceeds of such sale or sales have been distributed to the holders of VCAM
Common Stock, the Exchange Agent will hold such proceeds in trust for the
holders of VCAM Common Stock (the "Common Shares Trust"). All commissions,
transfer taxes and other out-of-pocket transaction costs, including the expenses
and compensation of the Exchange Agent incurred in connection with such sale of
the Excess Shares shall be paid by ADP. The Exchange Agent shall determine the
portion of the Common Shares Trust to which each holder of VCAM Common Stock
shall be entitled, if any, by multiplying the amount of the aggregate net
proceeds comprising the Common Shares Trust by a fraction, the numerator of
which is the amount of the fractional share interest to which such holder of
VCAM Common Stock is entitled and the denominator of which is the aggregate
amount of fractional share interests to which all holders of VCAM Common Stock
are entitled; provided, however, that in lieu of the foregoing, at the sole
option of ADP, ADP may instead satisfy payment with respect to such Excess
Shares by delivering to the Exchange Agent reasonably promptly following the
Effective Time cash (without interest) in an amount equal to the aggregate
amount of all such Excess Shares multiplied by the closing price per share of
ADP Common Stock on the NYSE on the trading day immediately prior to the
Effective Time.

                           (iv) As soon as practicable after the determination
of the amount of cash, if any, to be paid to holders of VCAM Common Stock in
lieu of any fractional share interests, the Exchange Agent shall make available
such amounts to such holders of VCAM Common Stock.

                  (f) Termination of Exchange Fund. Any portion of the Exchange
Fund and Common Shares Trust which remains undistributed to the
<PAGE>

                                                                               8

stockholders of VCAM for six months after the Effective Time shall, upon demand,
be delivered to ADP, and any stockholders of VCAM who have not theretofore
complied with this Article II shall thereafter look only to ADP for payment of
their claim for ADP Common Stock, cash in lieu of fractional shares and any
dividends or distributions with respect to ADP Common Stock.

                  (g) No Liability. Neither ADP nor VCAM shall be liable to any
holder of shares of VCAM Common Stock or ADP Common Stock, as the case may be,
for such shares (or dividends or distributions with respect thereto) or cash
from the Common Shares Trust delivered to a public official pursuant to any
applicable abandoned property, escheat or similar law.

                  (h) Withholding Rights. ADP or the Exchange Agent shall be
entitled to deduct and withhold from the consideration otherwise payable
pursuant to this Agreement to any holder of shares of VCAM Common Stock such
amounts as ADP or the Exchange Agent is required to deduct and withhold with
respect to the making of such payment under the Code, or any provision of state,
local or foreign tax law. To the extent that amounts are so withheld by ADP or
the Exchange Agent, such withheld amounts shall be treated for all purposes of
this Agreement as having been paid to the holder of the shares of VCAM Common
Stock in respect of which such deduction and withholding was made by ADP or the
Exchange Agent.

         2.3 Stock Options. (a) At the Effective Time, each outstanding option
to purchase shares of VCAM Common Stock (a "VCAM Stock Option") issued pursuant
to the VCAM Stock Plans, whether vested or unvested, shall be assumed by ADP.
Each VCAM Stock Option shall be deemed, without further action on the part of
ADP or the holders of such VCAM Stock Options, to constitute an option to
acquire, on the same terms and conditions as were applicable under such VCAM
Stock Option (except to the extent that such terms and conditions may be altered
in accordance with their terms as a result of the transactions contemplated
hereby including accelerated vesting of VCAM Stock Options which shall occur by
virtue of consummation of the Merger to the extent required with respect to the
VCAM Stock Options set forth in Section 3.1(c) of the VCAM Disclosure Schedule),
shares of ADP Common Stock in such amount and at the exercise price provided
below:

                           (i) the number of shares of ADP Common Stock to be
subject to the option (as adjusted) shall be equal to the product of (x) the
number of shares of VCAM Common Stock subject to the original option and (y) the
Exchange Ratio (rounded to four decimal points);

                           (ii) the exercise price per share of ADP Common Stock
under the option (as adjusted) shall be equal to (x) the exercise price per
share of VCAM Common Stock under the original option divided by (y) the Exchange
Ratio (rounded to the nearest $0.01); and
<PAGE>

                                                                               9

                           (iii) in accordance with the terms of the VCAM Stock
Option Plan under which the VCAM Stock Options were issued, fractional shares of
any assumed VCAM Stock Options resulting from the adjustments set forth in this
Section 2.3(a) shall be eliminated.

         In the case of any option to which section 421 of the Code applies by
reason of its qualification under any of sections 422-424 of the Code, the
exercise price, the number of shares purchasable pursuant to such option and the
terms and conditions of exercise of such option shall be effected in a manner
consistent with the requirements of section 424(a) of the Code.

                  (b) As soon as practicable after the Effective Time, ADP shall
deliver to the holders of VCAM Stock Options appropriate notices setting forth
such holders' rights pursuant to the respective VCAM Stock Plans and the
agreements evidencing the grants of such VCAM Stock Options and that such
options and the related option agreements shall be assumed by ADP and shall
continue in effect on the same terms and conditions (subject to the adjustments
required by this Section 2.3 after giving effect to the Merger).

                  (c) ADP shall take all corporate action necessary to reserve
for issuance a sufficient number of shares of ADP Common Stock for delivery upon
exercise of the VCAM Stock Options assumed in accordance with this Section 2.3.
No later than the Effective Time, ADP shall prepare and file a registration
statement on Form S-8 (or any successor or other appropriate forms), or another
appropriate form with respect to the shares of ADP Common Stock subject to such
options and shall use its reasonable commercial efforts to maintain the
effectiveness of such registration statement or registration statements (and
maintain the current status of the prospectus or prospectuses contained therein)
for so long as such options remain outstanding and cause such shares to be
listed on the NYSE.

                                   ARTICLE III

                 REPRESENTATIONS AND WARRANTIES OF VCAM AND ADP

         3.1 Representations and Warranties of VCAM. VCAM represents and
warrants to ADP as follows:

                  (a) Organization, Standing and Corporate Power; Subsidiaries.
Each of VCAM and its Subsidiaries is a corporation duly organized, validly
existing and in good standing under the laws of its jurisdiction of
incorporation or organization, has all requisite power and authority to own,
lease and operate its properties and to carry on its business as now being
conducted, and is duly qualified and in good standing to do business in each
jurisdiction in which the nature of its business or the ownership or leasing of
its properties makes such qualification
<PAGE>

                                                                              10

necessary, other than in such jurisdictions where the failure so to qualify
would not have a Material Adverse Effect with respect to VCAM. Section 3.1(a) of
the disclosure schedule delivered to ADP by VCAM on or prior to the date hereof
(the "VCAM Disclosure Schedule") sets forth a true and complete list of all of
VCAM's Subsidiaries, including (x) the jurisdiction of incorporation or
organization of each such Subsidiary and (y) the percentage of each such
Subsidiary's outstanding capital stock or other ownership interest owned by VCAM
and/or another Subsidiary of VCAM, as the case may be, if less than 100%. All of
the outstanding shares of capital stock or other ownership interests in each of
the Significant Subsidiaries of VCAM are duly authorized, validly issued, fully
paid and nonassessable and, except as set forth in Section 3.1(a) of the VCAM
Disclosure Schedule, are owned (of record and beneficially) by VCAM and/or by
another Subsidiary of VCAM, as the case may be, free and clear of all pledges,
claims, options, rights of first refusal, liens, charges, encumbrances and
security interests of any kind or nature whatsoever (collectively, "Liens"), and
not subject to preemptive rights created by statute, such Subsidiary's
respective Certificate of Incorporation or By-laws or equivalent organizational
documents or any agreement to which such Subsidiary is a party or by which such
Subsidiary is bound. Other than as set forth in Section 3.1(a) of the VCAM
Disclosure Schedule or in the VCAM SEC Documents, VCAM does not directly or
indirectly own any material equity interest in any Person.

                  (b) Certificate of Incorporation and By-laws. Complete and
correct copies of the Certificate of Incorporation and By-laws or equivalent
organiza tional documents, each as amended to date, of VCAM and each of its
Significant Subsidiaries have been delivered to ADP prior to the date hereof.
The Certificates of Incorporation, By-laws and equivalent organizational
documents of VCAM and each of its Significant Subsidiaries are in full force and
effect. Neither VCAM nor any of its Significant Subsidiaries is in violation of
any material provision of its Certificate of Incorporation, By-laws or
equivalent organizational documents.

                  (c) Capitalization. As of the date hereof, the authorized
capital stock of VCAM consists of (i) 60,000,000 shares of VCAM Common Stock of
which, (A) 15,733,031 shares are issued and outstanding, all of which are duly
authorized, validly issued, fully paid and nonassessable and not subject to
preemptive rights, of which 31,224 shares are held in the treasury, or by a
Subsidiary, of VCAM, and (B) 2,677,160 shares are reserved for future issuance
for the exercise of stock options with a term, exercise price, vesting schedule
and other material terms set forth separately for each of VCAM's stock option
plans in Section 3.1(c) of the VCAM Disclosure Schedule and (ii) 20,000,000
shares of preferred stock, par value $.01 per share, of VCAM of which none is
issued and outstanding. Except as described in this Section 3.1(c) or in Section
3.1(c) of the VCAM Disclosure Schedule, no shares of the capital stock or other
equity securities of VCAM are authorized, issued or outstanding, or reserved for
any other purpose, and there are no options, warrants or other rights (including
registration rights), agreements, arrangements or commitments of any character
(including, without limitation,
<PAGE>

                                                                              11

obligations to issue shares as the deferred purchase price for acquisitions of
stock or assets of third parties) to which VCAM or any of its Subsidiaries is a
party relating to the issued or unissued capital stock or other equity
securities or ownership interests of VCAM or any of its Subsidiaries or
obligating VCAM or any of its Subsidiaries to grant, issue or sell any shares of

respects with applicable accounting requirements and with the rules and
regulations of the SEC with respect thereto, have been prepared in accordance

all other statutes, orders, rules or regulations, specifically including the
reporting and disclosure requirements of Part 1 of Title I, and Title IV, of

         or a "defined benefit plan" as such term is defined in Section 3(35) of
         ERISA. Except as set forth in Section 3.1(l) of the VCAM Disclosure
         Schedule, each of the Employee Benefit Plans that is subject to ERISA
         is and has at all times been in substantial compliance (both in form

         meaning of Section 401(a) of the Code has received a favorable
         determination letter that the plan complies with the Tax Reform Act of

         or any trust related thereto or, to the knowledge of VCAM, by, on
         behalf of or against any fiduciary of such plans.

                           (vi) Except as set forth in Section 3.1(l) of the

or any of its Subsidiaries: (A) entitle any individual to severance pay; (B)
accelerate the time of payment or vesting of, increase the amount of, or satisfy
a condition to the com pensation due to any individual under any Employee

payment" under Code section 280G(b)(1).

                           (vii) Except as set forth in Section 3.1(l) of the
VCAM Disclosure Schedule, each Employee Benefit Plan may be amended or
terminated in accordance with applicable law on or at any time after the
Effective Time.

                           (viii) Except as set forth in Section 3.1(l) of the
VCAM Disclosure Schedule, (A) neither VCAM nor any of its Subsidiaries has or
will have any liability or obligation under any Employee Benefit Plan which
provides medical or death benefits with respect to current or former employees
of VCAM or and of its Subsidiaries beyond their termination of employment (other
than coverage mandated by law); and (B) each of VCAM, its Subsidiaries and their
respective ERISA Affiliates which maintains a "group health plan," within the
meaning of Sections 601 et seq. of ERISA ("COBRA"), has materially complied with
the notice and health care continuation requirements of COBRA.

                           (ix) No "prohibited transaction" (as such term is
defined in Section 406 of ERISA or Section 4975 of the Code) has occurred with
respect to any Employee Benefit Plan subject to ERISA, other than such a
transaction subject to an administrative or statutory exemption, with respect to
which a tax, penalty or other amount may reasonably be expected to be imposed on
VCAM or any of its Subsidiaries or their respective ERISA Affiliates.

                           (x) Except as set forth in Section 3.1(l) of the VCAM
Disclosure Schedule, no violation of ERISA has occurred with respect to the
filing of applicable reports, documents and notices regarding any Employee
Benefit Plan with the Secretary of Labor or the Secretary of the Treasury or the
furnishing of such documents to the participants or beneficiaries of any
Employee Benefit Plan.

                           (xi) Any bonding required with respect to any
Employee Benefit Plan in accordance with applicable provisions of ERISA has been
obtained and is in full force and effect.

                           (xii) None of VCAM or any of its Subsidiaries, or any
of their respective ERISA Affiliates, or any organization with respect to which

4069 of ERISA.

                           (xiii) No liability under any Employee Benefit Plan

by each other nationally recognized rating agency.

                           (xiv) To VCAM's knowledge, there has been no "mass
layoff" or "plant closing," as each such term is defined in the WARN, with

attempts underway with respect to any employees of VCAM, any of its Subsidiaries
or any of their respective clients. There is no pending or, to the knowledge of
VCAM, threatened labor dispute, strike or work stoppage involving such
employees. To the knowledge of VCAM, neither VCAM nor any of its Subsidiaries
nor any of their respective clients has committed any unfair labor practices (as
defined in the National Labor Relations Acts of 1947, as amended) in connection
with the operation of its business, and except as set forth in Section 3.1(l) of

standing required to be described in or filed as an exhibit to any VCAM SEC

the Exchange Act, as the case may be. All such contracts, agreements and
understanding are, unless terminated or expired, valid and binding and are in
full force and effect and enforceable in accordance with their respective terms,
except where the failure to be so enforceable could not reasonably be expected
to have a Material Adverse Effect with respect to VCAM. Except for the VCAM
Required Consents and except as set forth in Section 3.1(m) of the VCAM
Disclosure Schedule, (i) no approval or consent of, or notice to, any Person is
needed in order that such contract, agreement or understanding shall continue in
full force and effect in accordance with its terms without penalty, acceleration
or rights of early termination following the consummation of the transactions
contemplated by this Agreement, and (ii) VCAM is not in violation or breach of
or in default under any such contract, agreement or

understanding nor to VCAM's knowledge is any other party to any such contract,
agreement or understanding in violation, breach or default thereof except for
any violations, breaches or defaults which could not reasonably be expected to
have a Material Adverse Effect with respect to VCAM. With respect to any
professional employer organization agreement to which VCAM or any of its
Subsidiaries is a party, whether or not such agreement is currently in effect,
Section 3.1(m) of the VCAM Disclosure Schedule sets forth as of the date hereof

or reflected in the notes thereto or in the notes to VCAM's consolidated
financial statements as at and for the year ended December 31, 1997, or (ii)

and each of its Subsidiaries is in material compliance with all applicable
Environmental Laws, and has fully disclosed all known material past and present
non-compliance with Environmental Laws, and all known past discharges,
emissions, leaking or releases known to VCAM of any substance or waste regulated
under or defined by Environmental Laws that could reasonably be expected to form
the basis of any claim, action, suit, proceeding, hearing or investigation under
any applicable Environmental Laws;(D) neither VCAM nor any of its Subsidiaries
has received notice of any past or present events, conditions, circumstances,
activities, practices, incidents, actions or plans that have resulted in or
threaten to result in any common law or legal liability, or otherwise form the
basis of any claim, action, suit, proceeding, hearing or investigation under any
applicable Environmental Laws; and (E) neither VCAM nor any of its Subsidiaries
has generated, used, treated, disposed of, released or stored Hazardous
Materials on, or transported Hazardous Material in any material quantities to or
from, any owned or leased property; provided, however, that clauses (A) through
(E)

                                                                              21

(iv) any sale, disposition or other transfer of assets or properties of VCAM or
its Subsidiaries (other than the sale of inventory in the ordinary course of
business) in excess of $500,000 individually or $2,000,000 in the aggregate; or
(v) as of the date hereof, any change, occurrence or circumstance of any
character (whether or not in the ordinary course of business) that, individually
or in the aggregate, has had or could reasonably be expected to have a Material
Adverse Effect with respect to VCAM.

                  (p) Information Supplied. None of the information supplied or
to be supplied by VCAM for inclusion or incorporation by reference in (i) the

connection with the meeting of the VCAM stockholders called in connection with
the Merger (the "Proxy Statement") will, at the time the Registration Statement
is filed with the SEC, at any time it is amended or supplemented or at the time
it becomes effective under the Securities Act or at the time the Proxy Statement
is mailed to the VCAM stockholders, as the case may be, contain any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary to make the statements therein not misleading in
light of the circumstances in which they were made.

                  (q) Real Estate.

                           (i) Section 3.1(q)(i) of the VCAM Disclosure Schedule

refusal, easement, restrictive covenant, encroachment or other survey defect,
encumbrance or other restriction or limitation except for any of the foregoing
which would not have a Material Adverse Effect with respect to VCAM.

                           (ii) Section 3.1(q)(ii) of the VCAM Disclosure
Schedule sets forth all material leases, subleases, licenses or other agreements
under which VCAM or any of its Subsidiaries uses or occupies, or has the right
to use or occupy, now or in the future, any real property or improvements
thereon (the "VCAM Real Property Leases"). Except as disclosed in the VCAM SEC
Documents, to VCAM's knowledge all VCAM Real Property Leases are valid and
binding on the lessors thereunder in accordance with their respective terms and
to VCAM's knowledge, there is not under any such VCAM Real Property Leases any
existing default, or any condition, event or act which with notice or lapse of
time or both would constitute such a default, which in either case, considered
individually or in the aggregate with all such other VCAM Real Property Leases
under which there is such a default, condition, event or act, has or will have a
Material Adverse Effect with respect to VCAM.

                           (iii) Except as set forth in Section 3.1(q)(iii) of
the VCAM Disclosure Schedule, Fleet Real Estate, Inc., a Rhode Island

therefor, technology, know-how, computer software programs or applications, and

not reasonably be expected to have a Material Adverse Effect with respect to
VCAM.

                                                                              23

                           (ii) Except as would not reasonably be expected to
have a Material Adverse Effect with respect to VCAM: VCAM is not, nor will it be
as a result of the consummation of the Merger and the transactions contemplated
by this Agreement or the performance of its obligations hereunder, in violation
of any licenses, sublicenses and other agreements as to which VCAM is a party
and pursuant to which VCAM is authorized to use any third-party patents,
trademarks, service marks and copyrights ("Third-Party Intellectual Property
Rights"). Except as would not reasonably be expected to have a Material Adverse
Effect with respect to VCAM, no claims with respect to the patents, registered
and material unregistered trademarks and service marks, registered copyrights,
trade names and any applications therefor owned by VCAM or any of its
Subsidiaries (the "VCAM Intellectual Property Rights"), any trade secret
material to VCAM, or Third Party Intellectual Property Rights to the extent
arising out of any use, reproduction or distribution of such Third Party
Intellectual Property Rights by or through VCAM or any of its Subsidiaries, are
currently pending or, to the knowledge of VCAM, are threatened by any Person.
Except as would not reasonably be expected to have a Material Adverse Effect
with respect to VCAM, VCAM does not know of any valid grounds for any bona fide
claims (A) against the use by VCAM or any of it Subsidiaries, of any trademarks,
trade names, trade secrets, copyrights, patents, technology, know-how or
computer software programs and applications used in the business of VCAM or any
of its Subsidiaries as currently conducted or as proposed to be conducted; (B)
challenging the ownership, validity or effectiveness of any of VCAM Intellectual
Property Rights or other trade secret material to VCAM; or (C) challenging the
license or legally enforceable right to use of the Third Party Intellectual
Rights by VCAM or any of its Subsidiaries.

                           (iii) To VCAM's knowledge and except as would not
reasonably be expected to have a Material Adverse Effect with respect to VCAM,
(A) all patents, registered trademarks, service marks and copyrights held by
VCAM are valid and subsisting and (B) there is no unauthorized use, infringement
or misappropriation of any of the VCAM Intellectual Property by any third party,
including any employee or former employee of VCAM or any of its Subsidiaries.

                  (s) Accounts Receivable. The accounts receivable of VCAM and
its Subsidiaries as reflected in the most recent financial statements contained
in the VCAM SEC Documents (the "VCAM Financial Statements"), to the extent
uncollected on the date hereof, and the accounts receivable reflected on the
books of VCAM and its Subsidiaries (i) have arisen in the ordinary course of
business of VCAM and its Subsidiaries and (ii) subject only to reserves for bad
debts computed in a manner consistent with past practice and reasonably
estimated to reflect the probable results of collection, have been collected or
are collectible in the ordinary course of business of VCAM and its Subsidiaries
in the aggregate recorded amounts shown in the VCAM Financial Statements in
accordance with their terms. Section 3.1(s) of the VCAM Disclosure Schedule sets
forth an accounts receivable report as of the date set forth in such schedule
listing all accounts receivable of
<PAGE>

                                                                              24

VCAM and its Subsidiaries indicating the amount and due date of each such
account receivable and reflecting the aging thereof in the following intervals
(except as otherwise noted in Section 3.1(s) of the VCAM Disclosure Schedule):
15-30 days, 31-60 days, 61-90 days, 91-120 days and greater than 120 days.

                  (t) Clients. Section 3.1(t) of the VCAM Disclosure Schedule
sets forth a list of as of the date set forth in such schedule (i) substantially
all of the clients of VCAM and its Subsidiaries, (ii) for each such client, the
amount of the dollar volume for the period beginning January 1, 1998 and ending
as of the Business Day second preceding the date hereof and the past due amount
thereof as of such Business Day (if any), and (iii) confirmation of whether a
written agreement exists between VCAM or any of its Subsidiaries and each such
client and the effective date of each such written agreement. The relationships
of VCAM and its Subsidiaries with such clients are good commercial working
relationships and, except as set forth in Section 3.1(t) of the VCAM Disclosure
Schedule, (i) no Person listed on Section 3.1(t) of the VCAM Disclosure Schedule
within the last twelve months has threatened in writing to cancel or otherwise
terminate the relationship of such Person with VCAM or any of its Subsidiaries.

                  (u) Investment Company Act. Each of VCAM and its Subsidiaries
either (i) is not an "investment company," or a company "controlled" by, or an
"affiliated company" with respect to, an "investment company," within the
meaning of the Investment Company Act of 1940, as amended (the "Investment
Company Act") or (ii) satisfies all conditions for an exemption from the
Investment Company Act, and, accordingly, neither VCAM nor any of its
Subsidiaries is required to be registered under the Investment Company Act.

                  (v) Brokers or Finders. No agent, broker, investment banker,
financial advisor or other Person retained by or on behalf of VCAM is or will be
entitled to any broker's or finder's fee or any other commission or similar fee
in connection with any of the transactions contemplated by this Agreement,
except for Goldman, Sachs & Co. whose fees and expenses will be paid by VCAM in
accordance with VCAM's agreement with such firm.

                  (w) Vote Required. The affirmative vote of a majority of the
votes that the holders of the outstanding shares of VCAM Common Stock are
entitled to cast with respect to the adoption and approval of this Agreement is
the only vote of the holders of any class or series of the capital stock of VCAM
necessary to approve the Merger and the other transactions contemplated hereby.

                  (x) Opinion of Financial Advisor. VCAM has received the oral
opinion of Goldman, Sachs & Co. (to be confirmed in writing with an opinion
dated the date hereof) to the effect that, as of such date, the Exchange Ratio
(as determined pursuant to Section 2.1(b)) is fair to VCAM's stockholders from a
financial point of view, a copy of which written opinion will be delivered to
ADP.

                                                                              25

                  (y) Accounting Matters. Neither VCAM nor, to its knowledge,
any of its Affiliates, has taken or agreed to take any action that would prevent
ADP from accounting for the business combination to be effected by the Merger as
a pooling-of-interests.

                  (z) Ownership of ADP Common Stock. As of the date hereof,
neither VCAM nor, to its knowledge, any of its affiliates or associates, (i)
beneficially owns, directly or indirectly, or (ii) are parties to any agreement,
arrangement or understanding for the purpose of acquiring, holding, voting or
disposing of, in each case, shares of capital stock of ADP, which in the
aggregate, represent 10% or more of the outstanding shares of capital stock of
ADP entitled to vote generally in the election of directors.

                  (aa) Appraisal Rights and Dissenters' Rights. The stockholders
of VCAM do not have appraisal or dissenters' rights in connection with the
Merger.

                  (bb) Year 2000 Compliance. VCAM has developed a plan (the "Y2K
Plan") to ensure that all computer hardware and software (including all computer
hardware and software contained in imbedded systems) used in and material to the
business of VCAM and its Subsidiaries (whether such hardware and software is
owned by VCAM or its Subsidiaries or is licensed from third parties)
(collectively, the "Technology Systems") is designed to operate prior to, during
and after the calendar year 2000 to accurately process date data (including, but
not limited to calculating, comparing and sequencing) from, into and between the
twentieth and twenty-first centuries, including leap year calculations (the
"Year 2000 Compliance"). It is currently contemplated that the Y2K Plan will be
completed by December 31, 1999 and VCAM and its Subsidiaries have in their good
faith reasonable judgment sufficient resources (including appropriate reserves
to the extent required by GAAP) to complete the Y2K Plan by such date. As of the
date hereof, the Y2K Plan with respect to the Pay-Plus Payroll application is
contemplated to be completed by March 31, 1999. Assuming the consummation of the
Y2K Plan, the occurrence of the calendar year 2000 will not cause a Material
Adverse Effect with respect to VCAM and its Subsidiaries. The Y2K Plan includes
reasonable steps to determine whether the failure of any third parties with
which VCAM and its Subsidiaries have a material relationship to achieve Year
2000 Compliance could, individually or in the aggregate, have a Material Adverse
Effect with respect to VCAM. VCAM and its Subsidiaries have confirmed, or intend
to confirm, with all material third party suppliers and/or clients that
communicate electronically with VCAM and its Subsidiaries that such
communications will not be disrupted and will continue to function properly
prior to, during and after the calendar year 2000 and that such communications
during the aforesaid time periods will not disrupt the Technology Systems or the
operations of VCAM and its Subsidiaries, except to the extent that the failure
to so function would not, individually or in the aggregate, have a Material
Adverse Effect with respect to VCAM.

Subsidiaries has been an insured, a named insured or otherwise the principal
beneficiary of coverage at any time within the past three years (except policies

                                    (C) the policy number and the period of

         such insurance policy and whether such policy would terminate or be
         terminable as a result of the consummation of the transactions
         contemplated by this Agreement);

                                    (D) the type, scope (including an indication
         of whether the coverage was on a claims made, occurrence or other
         basis) and amount (including a description of how deductibles,
         retentions and aggregates are calculated and operate) of coverage; and

                                    (E) the premium charged for the policy,
         including, without limitation, a description of any retroactive premium
         adjustments or other loss-sharing arrangements.

the VCAM Disclosure Schedule, with respect to each such insurance policy: (A)
the policy is legal, valid, binding and enforceable in accordance with its terms

or default or permit termination or modification, under the policy; (C) all
premiums charged for such policy have been paid when payment has become due and
payable thereunder and, there are no unfunded or unpaid premiums, loss costs or
retentions outstanding; (D) all liabilities with respect to such policy are

<PAGE>

                                                                              27

(F) to the knowledge of VCAM, no insurer on the policy has been declared
insolvent or placed into receivership, conservatorship or liquidation or
currently has a rating of "B+" or below from A.M. Best & Co. or a claims paying
ability rating of "BBB" or below from Standard & Poors, Inc ("Qualified
Carriers") and (G) there is no oral or written agreement or understanding which
amends, modifies or otherwise changes the terms of such policy.

                           (iii) Section 3.1(cc)(iii) of the VCAM Disclosure
Schedule sets forth, with respect to worker's compensation, all risks against
which VCAM and each of its Subsidiaries is self-insured or subject to a
deductible and details for the last three full calendar years (and the period
from the end of the last such calendar year to the Business Day Second preceding

or any of its Subsidiaries (x) been denied any material insurance or indemnity
bond coverage which it has requested, (y) made any material reduction in the
scope or amount of its insurance coverage, or, except as set forth in Section
3.1(cc)(v) of the VCAM Disclosure Schedule, received written notice from any of
its insurance carriers that any insurance premiums will be subject to increase
in an amount materially disproportionate to the amount of the increases with
respect thereto (or with respect to similar insurance) in prior years or that
any insurance coverage listed in Section 3.1(cc)(i) of the VCAM Disclosure
Schedule will not be available in the future substantially on the same terms as
are now in effect or (z) suffered any extraordinary increase in premium for
renewed coverage. Except as set forth in Section 3.1(cc)(v) of the VCAM
Disclosure Schedule, since January 1, 1996, no insurance carrier has canceled,
failed to renew or materially reduced any material insurance coverage for VCAM
or any of its Subsidiaries or given any written notice, not renew or reduce any
such coverage.

                  (dd) Full Disclosure. All documents, Contracts, instruments,
certificates, notices, consents, affidavits, letters, statements, schedules
(including Schedules to this Agreement), exhibits and any other papers

contains an untrue statement of a material fact or omits to state a material
fact required to be stated therein or necessary to make the statements made, in

material) that ADP or its respective Subsidiaries was required to file with the

than preliminary material) complied in all material respects with the
requirements of the Securities Act or the Exchange Act as applicable, and the

                                                                              29

SEC thereunder applicable to such ADP SEC Documents, and none of the ADP SEC
Documents (including all financial statements included therein and exhibits and
schedules thereto and documents incorporated by reference therein) contained any
untrue statement of a material fact or omitted to state a material fact required
to be stated therein or necessary to make the statements therein, in light of
the circum stances under which they were made, not misleading. The financial
statements of ADP and each Subsidiary of ADP included in the ADP SEC Documents
comply as to form in all material respects with applicable accounting
requirements and with the rules and regulations of the SEC with respect thereto,
have been prepared in accord ance with GAAP applied on a consistent basis during
the periods involved (except as may be indicated in the notes thereto or, in the
case of the unaudited financial statements, as permitted by the Exchange Act)
and fairly present in all material respects (subject, in the case of the
unaudited financial statements, to normal, recurring audit adjustments that,
individually and in the aggregate, were and will not be not material) the
consolidated financial position of ADP and/or the applicable Subsidiaries of ADP

                  (e) Authority. ADP and Sub have all requisite corporate power
and authority to enter into this Agreement and to perform their obligations
hereunder and to consummate the transactions contemplated hereby. The execution
and delivery of this Agreement and the consummation of the transactions
contemplated hereby have been duly and validly authorized by all necessary
corporate action on the part of ADP and Sub and no other corporate proceedings
on the part of ADP or Sub are necessary to authorize this Agreement or to
consummate the transactions contemplated hereby. This Agreement has been duly
and validly executed and delivered by ADP and Sub and constitutes a valid and
binding obligation of ADP and Sub enforceable against ADP in accordance with its
terms, subject to bankruptcy, insolvency, reorganization, moratorium and other
laws limiting creditors' rights generally and to general equitable principles.

                  (f) Government Approvals; Required Consents.

                           (i) No material consent, approval or authorization

or prior to the date hereof (the "ADP Disclosure Schedule") (any such consents,
approvals, authorizations, declarations, filings or notices specified in clauses
(A) through (F) being referred to as "ADP Governmental Approvals").

                           (ii) No material consent, approval or action of, or
filing with, or notice to, any Person (other than a Governmental Entity) shall
be required in connection with the execution or delivery by ADP or Sub of this
Agreement, the consummation by ADP and Sub of the transactions contemplated
hereby or compliance by ADP and Sub with the provisions hereof, other than as
set forth in Section 3.2(f)(ii) of the ADP Disclosure Schedule (the "ADP
Required Consents").

                  (g) Non-Contravention. The execution and delivery of this
Agreement by ADP and Sub does not, and the consummation of the transactions
contemplated hereby and compliance by ADP and Sub with the provisions hereof
will not, (i) conflict with or result in any violation of any provision of the
Certificate of Incorporation or By-laws, in each case as amended and/or
restated, of ADP and its Subsidiaries; (ii) if the ADP Required Consents are
obtained, result in any violation or breach of, or result in a modification of
the effect of, or constitute (with or without notice or lapse of time or both) a
default under or give rise to any right of termination, cancellation or
acceleration under, any contracts to which ADP and its Subsidiaries are a party
or by or to which any of them or any of their properties may be bound or
subject, or result in the creation of any Lien upon the properties of ADP and
its Subsidiaries in each case pursuant to the terms of any such Contract; or
(iii) if the ADP Governmental Approvals are obtained, result in any violation of
any law, statute, regulation, order, writ, judgment or decree of any
Governmental Entity applicable to ADP and its Subsidiaries other than with
respect to clauses (ii) and (iii) above, any such violations, breaches,
modifications, defaults, terminations, cancella tions, accelerations, Liens,
revocations or suspensions that, individually and in the aggregate, would not
have a Material Adverse Effect with respect to ADP.

                  (h) Information Supplied. None of the information supplied or
to be supplied by ADP for inclusion or incorporation by reference in the
Registra tion Statement will, at the time the Registration Statement is filed
with the SEC, at any time it is amended or supplemented or at the time it
becomes effective under the Securities Act, contain any untrue statement of a
material fact or omit to state any material fact required to be stated therein
or necessary to make the statements therein not misleading.

                  (i) Brokers or Finders. No agent, broker, investment banker,
financial advisor or other Person retained by or on behalf of ADP is or will be
entitled to any broker's or finder's fee or any other commission or similar fee
in connection with any of the transactions contemplated by this Agreement,
except Lehman Brothers whose fees and expenses will be paid by ADP in accordance
with ADP's agreement with such firm.

                  (j) Material Adverse Change. Since June 30, 1998, there has
not been a material adverse change in the business, assets, properties, results
of operations, prospects or financial condition of ADP and its Subsidiaries
taken as a whole.

                  (k) Accounting Matters. Neither ADP nor, to its knowledge, any
of its Affiliates, has taken or agreed to take any action that would prevent ADP
from accounting for the business combination to be effected by the Merger as a
pooling-of-interests.

                  (l) Tax Matters. Neither ADP nor Sub has taken or agreed to
take any action, or knows of any circumstances, that (without regard to any
action taken or agreed to be taken by VCAM or any of its Subsidiaries) would
prevent the Merger from qualifying as a reorganization within the meaning of
Sections 368(a)(1)(A) or 368(a)(2)(E) of the Code.

                                   ARTICLE IV

                                    COVENANTS

         4.1 Mutual Covenants of ADP and VCAM. Each of ADP and VCAM agrees that,
except as expressly contemplated or permitted by this Agreement, it shall (and
shall cause each of its Subsidiaries to) comply with the following covenants:

                  (a) Confidentiality. From and after the date hereof, each
party shall, and shall use its best efforts to cause its Affiliates and its and
their respective Agents to keep secret and hold in strictest confidence any and
all documents and information relating to the other party and its respective
Affiliates furnished to such first party (whether before or after the date
hereof) in connection with the transactions contemplated hereunder, other than
the following: (i) informa tion that has become generally available to the
public other than as a result of a wrongful disclosure by such party, its
Affiliates or its Agents; (ii) information that becomes available to such party
or an Agent of such party on a nonconfidential basis from a third party having
no obligation of confidentiality to a party to this Agreement and which has not
to the knowledge of the receiving party itself received such infor mation
directly or indirectly in breach of any such obligation of confidentiality;
(iii) information that is required to be disclosed by applicable law, judicial
order or pursu ant to any listing agreement with, or the rules or regulations
of, any securities exchange on which securities of such party or any such
Affiliate are listed or traded; provided that the party making such disclosure
or whose Affiliates or Agents are making such disclosure shall notify the other
party as promptly as practicable (and, if possible, prior to making such
disclosure) and shall use its reasonable best efforts to limit the scope of such
disclosure and seek confidential treatment of the information to
<PAGE>

                                                                              32

be disclosed; and (iv) disclosures made by any party as shall be reasonably
necessary in connection with obtaining the ADP Required Consents and/or the VCAM
Required Consents. Notwithstanding the foregoing, ADP and VCAM agree that the
Confidentiality Agreement, dated as of October 5, 1998 (the "Confidentiality
Agreement"), between ADP and VCAM shall remain in full force and effect and
shall control to the extent of any conflict between the terms of this Section
4.1(a) and the Confidentiality Agreement.

                  (b) Publicity. Except as otherwise required by applicable law
or the rules or regulations of any securities exchange on which the securities
of such party or any Affiliate of such party are listed or traded as determined
in the good faith opinion of the disclosing person's counsel, until the earlier
of (i) the date on which this Agreement ceases to be in effect and (ii) the
Closing Date, no party shall issue or cause the publication of any press release
or other public announcement with respect to the transactions contemplated by
this Agreement without the consent of the other party and in any event each
party agrees that it will give the other party reasonable opportunity to review
and comment upon any such release or announcement prior to publication of the
same.

                  (c) Preparation of the Proxy Statement and the Registration
Statement. As soon as practicable following the date of this Agreement, at the
direction of, and with all reasonably necessary assistance from, VCAM, ADP shall
prepare and cause to be filed with the SEC the Registration Statement, in which
the Proxy Statement will be included as part of a Proxy Statement/Prospectus.
Each party shall provide the other party and its Agents with reasonable
opportunity to review and comment upon the Registration Statement, including all
amendments thereto and all supplements to the Proxy Statement contained therein,
prior to the filing thereof with the SEC and/or the distribution thereof to the
stockholders of VCAM, and shall make all reasonable changes thereto requested by
such other party or its Agents. Each party hereto shall use its reasonable
commercial efforts to have the Registration Statement declared effective by the
SEC as promptly as practicable consistent with a desired Effective Time of on or
prior to February 28, 1999; provided, that the failure of the Effective Time to
have occurred on or prior to February 28, 1999 shall not be considered to be a
breach of this Agreement. Each party shall provide and shall be deemed to have
provided the other party with the information concerning it required to be
included in the Registration Statement. ADP shall take any action required to be
taken under any applicable state securities laws in connection with the issuance
of the Shares of ADP Common Stock to be issued in the Merger pursuant to this
Agreement.

                  (d) Satisfaction of Conditions; Additional Agreements. Subject
to the terms and conditions of this Agreement, each party hereto agrees to use
its reasonable commercial efforts to cause the conditions set forth in Article
VI of this Agreement to be satisfied, and to take, or cause to be taken, all
action and to do, or cause to be done, all things necessary, proper or advisable
under applicable laws and
<PAGE>

                                                                              33

transac tions contemplated by this Agreement consistent with a desired Effective
Time of on or prior to February 28, 1999, including obtaining any VCAM Required
Consents or VCAM Governmental Approvals and cooperating fully with the other
party, including by provision of information and making of all necessary filings
in connection with, among other things, the HSR Act; provided, that the failure
of the Effective Time to have occurred on or prior to February 28, 1999 shall
not be considered to be a breach of this Agreement. In case at any time after
the Closing Date any further action is necessary or desirable to carry out the
purposes of this Agreement, each party shall take all such necessary action.

                  (e) Other Actions. From the date hereof through the Closing
Date, each of ADP and VCAM shall not, and shall cause its Subsidiaries not to,
take any action that would or is reasonably likely to result in any of the
represen tations and warranties of ADP or VCAM, as the case may be, set forth in
this Agreement being untrue in any material respect as of the date made, or in
any of the conditions to the Closing set forth in Article VI of this Agreement
not being satisfied. ADP shall take all actions reasonably necessary to comply
with Rule 144(c) under the Securities Act.

                  (f) Advice of Changes; SEC Documents. Subject to applicable
law, each party shall confer on a regular and frequent basis with the other,
report on operational matters and promptly advise the other orally and in
writing of (i) any material notice or other communication from any third party
alleging that the consent of such third party is or may be required in
connection with the transactions contemplated by this Agreement; (ii) any
material notice or other communication from any regulatory authority or national
securities exchange in connection with the transactions contemplated by this
Agreement; and (iii) any claims, actions, proceedings or investigations
commenced or, to the best of such party's knowledge, threatened, involving or
affecting such party or any of its Subsidiaries, or any of its property or
assets, or, to the best of such party's knowledge, any employee, consul tant,
director or officer, in his or her capacity as such, of such party or any of its
Subsidiaries, which relates to the consummation of the Merger or the other
transactions contemplated by this Agreement.

                  (g) Legal Conditions to Merger. Each of VCAM, ADP and Sub will
take all reasonable actions necessary to comply promptly with all legal
requirements which may be imposed on itself with respect to the Merger
(including furnishing all information required under the HSR Act and in
connection with approvals of or filings with any other Governmental Entity) and
will promptly cooperate with and furnish information to each other in connection
with any such requirements imposed upon any of them or any of their Subsidiaries
in connection with the Merger. Each of VCAM, ADP and Sub will, and will cause
its Subsidiaries to, take all reasonable actions necessary to obtain (and will
cooperate with each other in obtaining) any consent, authorization, order or
approval of, or any exemption by,
<PAGE>

                                                                              34

any Governmental Entity or other public or private third party, required to be

with the Merger or the taking of any action contemplated thereby or by this
Agreement or the Stock Option Agreement.

         4.2 Covenants of VCAM. During the period from the date of this
Agreement and continuing until the Closing Date, VCAM agrees that, except as
expressly contemplated or permitted by this Agreement, or to the extent that ADP
shall otherwise consent in writing (which consent may be withheld in its sole
discretion):

                  (a) Access to Information. Subject to Section 4.1(a), upon
reasonable notice, VCAM shall, and shall cause its Subsidiaries to, afford to
ADP and its Agents, access, during normal business hours during the period prior

records and, during such period, VCAM shall, and shall cause its Subsidiaries
to, promptly furnish or otherwise make available to ADP (i) a copy of each
report, schedule, registration statement and other document filed or received by
any of them during such period pursuant to the requirements of Federal
securities laws and (ii) all other information concerning its business,
properties and personnel as ADP may reasonably request.

                  (b) Ordinary Course. VCAM shall, and shall cause its
Subsidiaries to, carry on their respective businesses in the usual, regular and
ordinary course in substantially the same manner as heretofore conducted and use
its commercially reasonable efforts to preserve intact their current business
organizations, retain and keep available the services of their current officers
and employees and preserve their relationships with customers, suppliers,
contractors, distributors, licensors, licensees and others having business
dealings with them to the end that their goodwill and ongoing businesses shall
not be impaired in any material respect at the Closing Date (it being understood
and agreed by ADP and VCAM that this Section 4.2(b) is a material covenant and
ADP is relying on VCAM's compliance with the provisions of this covenant between
the date hereof and the Closing Date for purposes of Section 6.2(b) hereof).

stockholders as promptly as practicable after the effectiveness of the Form S-4,
among other things, consider and vote upon this Agreement and the Merger (the
"Stockholders' Meeting"), and VCAM shall consult with ADP in connection
therewith; provided, that the failure of the Effective Time to have occurred on
or prior to February 28, 1999 shall not be considered to be a breach of this
Agreement. VCAM will use its best efforts to obtain the requisite stockholder
approval as soon as practicable after the date hereof. Without limiting the
generality of the foregoing, VCAM agrees that its obligations pursuant to the
first two sentences of this Section 4.2(c) shall not be affected by (i) the
commencement, public proposal, public disclosure or communication to ADP of any
Transaction Proposal or (ii) the withdrawal or modification by the Board of
Directors of VCAM of its approval or recommendation of this Agreement or the
Merger. Subject to the provisions of Sections 4.2(d) and 4.2(e) hereof, the
Board of Directors of VCAM shall recommend that VCAM's stockholders vote in
favor of the adoption and approval of this Agreement (the "Recommendation") and

                  (d) No Solicitation. Neither VCAM nor any of its Subsidiaries
shall, nor shall it or any of its Subsidiaries authorize or permit any of their
respective Agents to, (i) solicit, initiate, encourage (including by way of
furnishing information or assistance) or take any other action to facilitate,
any inquiry or the making of any proposal which constitutes, or may reasonably
be expected to lead to, any acquisition or purchase of a substantial amount of
assets of, or any equity interest in, VCAM or any of its Subsidiaries or any
tender offer (including a self tender offer) or exchange offer, merger,
consolidation, business combination, sale of substantially all assets, sale of
securities, recapitalization, liquidation, dissolution or similar transaction
involving VCAM or any of its Subsidiaries (other than the transactions
contemplated by this Agreement) or any other material corporate transaction the
consummation of which would or could reasonably be expected to impede, interfere
with, prevent or materially delay the Merger (collectively, "Transaction
Proposals") or agree to or endorse any Transaction Proposal or (ii) propose,
enter into or participate in any discussions or negotiations regarding any of
the foregoing, or furnish to any other Person any information with respect to
its business, properties or assets or any of the foregoing, or otherwise
cooperate in any way with, or assist or participate in, facilitate or encourage,
any effort or attempt by any other Person to do or seek any of the foregoing;
provided, however, that the foregoing clauses (i) and (ii) shall not prohibit
VCAM from, prior to the Stockholders' Meeting (A) furnishing information
pursuant to an appropriate confiden tiality letter concerning VCAM and its
businesses, properties or assets to a third party which has made an unsolicited
Qualified Transaction Proposal (as defined below), (B) engaging in discussions
or negotiations with such a third party which has made an unsolicited Qualified
Transaction Proposal or (C) following receipt of an unsolicited Qualified
Transaction Proposal, taking and disclosing to its shareholders a position with
respect to such Qualified Transaction Proposal, but in each case referred to in
the foregoing clauses (A) through (C) only after the Board of Directors of VCAM
concludes in good faith, following receipt of a written opinion addressed to
VCAM from outside counsel, that such action is necessary for the Board of
Directors of VCAM to comply with its fiduciary obligations to stockholders under
applicable law and that the third party which made the unsolicited Qualified
Transaction Proposal has the ability and the financial wherewithal to consummate
a Superior Acquisition Proposal (as defined below). If the Board of Directors of
VCAM receives a Trans action Proposal, then VCAM shall immediately (and in any
event within 24 hours) inform ADP of the material terms and conditions of such
proposal and the identity of the Person making it and shall keep ADP fully
informed regarding any significant details or developments with respect to any
such Transaction Proposal and of all significant steps it is taking in response
to such Transaction Proposal. For purposes of this Agreement, the term
"Qualified Transaction Proposal" shall mean a Transac tion Proposal that the
Board of Directors of VCAM determines in good faith after consultation with its
outside financial advisors, is reasonably capable of being

                                                                              38

financed and is not subject to any material contingencies relating to financing.
Without limiting the foregoing, it is understood that any violation of the
restrictions set forth in this Section 4.2(d) by (or at the direction of) an
officer, director of or any investment banker, attorney, accountant, Agent or
other advisor or representative of VCAM or any of VCAM's Subsidiaries, whether
or not such person is purporting to act on behalf of VCAM, an VCAM Subsidiary or
otherwise, shall be deemed to be a breach of this paragraph by VCAM. VCAM
immediately shall cease and cause to be terminated all existing discussions or
negotiations with any persons conducted heretofore with respect to, or that
could reasonably be expected to lead to, any Qualified Transaction Proposal.

                  (e) Superior Acquisition Proposal. Neither the Board of
Directors of VCAM nor any committee thereof shall (i) withdraw or modify, or
propose publicly to withdraw or modify, in a manner adverse to ADP, the
Recommendation or any approval or recommendation by the Board of Directors of
VCAM or any committee thereof of this Agreement or the Merger or (ii) approve or
recommend, or propose to approve or recommend, any Qualified Transaction
Proposal. Notwithstanding the foregoing, the Board of Directors of VCAM, to the
extent it concludes in good faith, following receipt of a written opinion
addressed to VCAM from outside counsel, that such action is necessary for the
Board of Directors of VCAM to comply with its fiduciary obligations to
stockholders under applicable law, may approve or recommend (and, in connection
therewith, withdraw or modify the Recommendation or its approval of this
Agreement or the Merger) a Superior Acquisition Proposal (as defined below). For
purposes of this Agreement, "Superior Acquisition Proposal" means a bona fide
written proposal made by a third party to acquire VCAM pursuant to a tender or
exchange offer, a merger, a share exchange, a sale of all or substantially all
of its assets or otherwise, in any such case, on terms which a majority of the
members of the Board of Directors of VCAM determines in their good faith
judgment (after consultation with independent financial advisors) to be more
favorable to VCAM and its stockholders than the Merger and for which financing,
to the extent required, is then fully committed or which, in the good faith
judgment of a majority of such members (after consultation with independent
financial advisors), is reasonably capable of being financed by such third
party.

                  (f) Affiliates. Concurrently with the execution of this
Agreement, VCAM is delivering to ADP (i) a letter identifying all Persons who,
to the knowledge of VCAM, may be deemed to be "affiliates" of VCAM under Rule
145 under the Securities Act, including, without limitation, all directors and
executive officers of VCAM, and (ii) not later than 30 days prior to the
Stockholders' Meeting copies of letter agreements, each in the form prepared by
ADP and reasonably acceptable to VCAM, executed by each such Person so
identified as an "affiliate" of VCAM (the letters described in clauses (i) and
(ii) being collectively referred to as "Affiliate Letters").

                                                                              39

                  (g) Compliance with Laws. VCAM agrees to conduct its
businesses and cause the businesses of its Subsidiaries to be conducted in
material compliance with all applicable laws and regulations.

                  (h) Advice of Changes. VCAM shall promptly advise ADP in
writing of any claims, actions, proceedings or investigations commenced or, to
the best of VCAM's knowledge, threatened, involving or affecting VCAM or any of
its Subsidiaries, or any of VCAM's property or assets, or, to the best of VCAM's
knowledge, any employee, consultant, director or officer, in his or her capacity
as such, of VCAM or any of its Subsidiaries, which, if pending on the date of
this Agreement, would have been required to have been disclosed in the VCAM
Disclosure Schedule.

                  (i) Pooling Letters. VCAM shall use commercially reasonable
efforts to cause Price Waterhouse Coopers LLP to deliver a letter dated the
Closing Date stating in their opinion that VCAM is a poolable entity for
accounting purposes and VCAM shall deliver a letter addressed to Deloitte &
Touche LLC to the same effect.

         4.3 Listing. ADP shall use its best efforts to cause the shares of ADP
Common Stock to be issued in the Merger to be approved for listing on the NYSE,
subject to official notice of issuance.

                                    ARTICLE V

                              ADDITIONAL AGREEMENTS

         5.1 Indemnification; Directors' and Officers' Insurance.

                  (a) VCAM shall, and from and after the Effective Time, ADP and
the Surviving Corporation (each, an "Indemnifying Party") shall, indemnify,
defend and hold harmless each person who is now, or has been at any time prior
to the date hereof or who becomes prior to the Effective Time, an officer,
director or employee of VCAM or any of its Subsidiaries (collectively, the
"Indemnified Parties") against (i) all losses, claims, damages, costs, expenses,
liabilities or judgments or amounts that are paid in settlement with the
approval of the Indemnifying Party (which approval shall not be unreasonably
withheld) of or in connection with any claim, action, suit, proceeding or
investigation based in whole or in part on or arising in whole or in part out of
the fact that such person is or was a director, officer or employee of VCAM or
any Subsidiary and arising out of actions or omissions, occurring at or prior to
the Effective Time and whether asserted or claimed prior to, or at or after, the
Effective Time ("Indemnified Liabilities") and (ii) all Indemnified Liabilities
based in whole or in part on, or arising in whole or in part out of, or
pertaining to this Agreement or the transactions contemplated hereby;
<PAGE>

                                                                              40

provided, that in the case of clauses (i) and (ii) above, each Indemnifying
Party shall only be required to indemnify an Indemnified Party pursuant to this
Section 5.1 to the extent a corporation is permitted under the law of the state
of incorporation of the Indemnifying Party to indemnify its own directors,
officers and employees, as the case may be (and ADP and the Surviving
Corporation, as the case may be, will pay expenses in advance of the final
disposition of any such action or proceeding to each Indemnified Party to the
full extent permitted by law upon receipt of any undertaking required or
contemplated by applicable law). In addition, the articles of incorporation and
by-laws of the Surviving Corporation and its successors and assigns shall
contain provisions with respect to indemnification no less favorable in all
material respects to the present and former directors and officers of VCAM than
those in effect in the Articles of Incorporation of VCAM and the By-laws of VCAM
as in effect on the date of this Agreement.

                  (b) Each Indemnified Party under this Section 5.1 will,
promptly after the receipt of notice of the commencement of any action or other
proceeding against such Indemnified Party in respect of which indemnity may be
sought from an Indemnifying Party under this Section 5.1, notify the
Indemnifying Party in writing of the commencement thereof. The omission of any
Indemnified Party so to notify an Indemnifying Party of any such action shall
not relieve such Indemnifying Party from any liability which it may have to such
Indemnified Party other than pursuant to this Section 5.1 or, unless, and only
to the extent that, such omission results in such Indemnifying Party's
forfeiture of substantive rights or defenses. In case any such action or other
proceeding shall be brought against any Indemnified Party and it shall notify
the Indemnifying Party of the commencement thereof, the Indemnifying Party shall
be entitled to participate therein and, to the extent that it may wish, to
assume the defense thereof, with counsel reasonably satis factory to such
Indemnified Party; provided, however, that any Indemnified Party may, at its own
expense, retain separate counsel to participate in such defense. Notwithstanding
the foregoing, in any action or proceeding in which both the Indemnifying Party
and an Indemnified Party is, or is reasonably likely to become, a party, such
Indemnified Party shall have the right to employ separate counsel at the
Indemnifying Party's expense and to control its own defense of such action or
proceeding if, in the reasonable written opinion of counsel to such Indemnified
Party, (a) there are or may be legal defenses available to such Indemnified
Party or to other Indemnified Parties that are different from or additional to
those available to the Indemnifying Party or (b) any conflict or potential
conflict exists between the Indemnifying Party and such Indemnified Party that
would make such separate representation advisable; provided, however, that in no
event shall the Indemnifying Party be required to pay fees and expenses under
this Section 5.1 for more than one firm of attorneys in any jurisdiction in any
one legal action or group of related legal actions. The Indemnifying Party shall
not, without the consent of the Indemnified Party (which consent shall not be
unreasonably withheld), consent to the entry of any judgment or enter into any
settlement which does not include as an unconditional term thereof the giving by
the claimant or plaintiff to such Indemnified Party of a release
<PAGE>

                                                                              41

from all liability in respect to such claim or litigation or which requires
action other than the payment of money by the Indemnifying Party. The rights
accorded to Indemnified Parties hereunder shall be in addition to any rights
that any Indemnified Party may have at common law, by separate agreement or
otherwise.

                  (c) For not less than six years after the Effective Time, ADP,
or the Surviving Corporation or their respective successors or assigns shall
maintain in effect directors' and officers' liability insurance with respect to
claims arising from facts or events arising prior to and including the Effective
Time covering the Indemnified Parties (which may include including such persons
in ADP's existing plans) who are currently covered by VCAM's existing directors'
and officers' liability insurance, on terms and conditions no less favorable to
such directors and officers than those in effect on the date hereof with respect
to ADP's officers and directors; provided, however, that in no event shall ADP
or the Surviving Corporation be required to expend pursuant to this Section
5.1(c) more than an amount equal to 200% of the current annual premiums paid by
VCAM for such insurance.

                  (d) The provisions of this Section 5.1 are intended to be for
the benefit of, and shall be enforceable by, each Indemnified Party, his or her
heirs and his or her representatives.

         5.2 Additional Agreements; Reasonable Efforts. Subject to the terms and
conditions of this Agreement, each of the parties hereto agrees to use all
reasonable efforts to take, or cause to be taken, all action and to do, or cause
to be done, all things necessary, proper or advisable under applicable laws and
regulations to consummate and make effective the transactions contemplated by
this Agreement, subject to the appropriate vote of stockholders of VCAM
described in Section 6.1(a), including cooperating fully with the other party,
including by provision of information and making of all necessary filings in
connection with, among other things, under the HSR Act. In case at any time
after the Effective Time any further action is necessary or desirable to carry
out the purposes of this Agreement or to vest the Surviving Corporation with
full title to all properties, assets, rights, approvals, immunities and
franchises of any party to this Agreement, the proper officers and directors of
each party to this Agreement shall take all such necessary action.

         5.3 Accounting Treatment. ADP and VCAM shall use reasonable best
efforts and shall cooperate fully to allow the Merger and other transactions
contemplated by this Agreement to be accounted for as a "pooling-of-interests"
in accordance with GAAP acceptable to the SEC.

         5.4 Tax Treatment. Each of ADP, Sub and VCAM shall use reasonable
commercial efforts to cause the Merger to qualify as a reorganization under the
provisions of Section 368(a) of the Code, including, without limitation,
forebearing from taking any action that would cause the Merger not to qualify as
a reorganization under the provisions of Section 368(a) of the Code.

         5.5 Employee Matters.

                  (a) ADP agrees that individuals who are employed by VCAM or
any of VCAM's Subsidiaries (other than client employees) immediately prior to
the Closing Date shall remain employees of VCAM or such Subsidiary as of the
Closing Date (each such employee, an "Affected Employee"); provided, however,
that nothing contained herein shall confer upon any Affected Employee the right
to continued employment by VCAM or any of its Subsidiaries for any period of
time after the Closing Date which is not otherwise required by law or contract.

                  (b) To the extent that any Affected Employees are moved by ADP
to any employee benefit plan maintained by ADP or any of its Subsidiaries, (i)
ADP shall, or shall cause such Subsidiary to, give such Affected Employees full
credit solely for the purposes of eligibility and vesting under such employee
benefits plans for such Affected Employee's service with ADP, VCAM or any
affiliate thereof to the same extent recognized immediately prior to the Closing
Date and (ii) such Affected Employees will not be subject to any limitations
regarding preexisting conditions under any such employee benefit plan; provided,
that the entry dates into such employee benefit plans for such Affected
Employees will be in the normal course of such plan's administration, which may
be the beginning of the plan year.

                  (c) After the Effective Time, until the date ADP determines in
its discretion to move Affected Employees to ADP employee health and welfare
benefit plans, ADP shall cause VCAM to maintain employee health and welfare
plans (but not bonus or equity-based plans) that are substantially comparable to
the health and welfare plans maintained by VCAM on the date hereof.

competent jurisdiction or other legal restraint or prohibition (an "Injunction")
restraining or preventing the consummation of the Merger or subjecting any party

of the Merger shall be in effect; provided, however, that the party invoking
this condition shall have used reasonable best efforts to have vacated such
Injunction.

                  (f) HSR Act. All HSR Act waiting periods shall have expired or
been terminated.

                  (g) Governmental and Regulatory Consents. All filings required
to be made prior to the Effective Time with, and all consents, approvals,

Shareholder pursuant to any note, bond, mortgage, indenture, contract,
agreement, lease, license, permit, franchise or other instrument or obligation
to which such Shareholder is a party or by which such Shareholder (or the Shares
held of record or Beneficially Owned by such Shareholder) is bound or affected,
except, in the case of clauses (ii) and (iii) of this Section 3.2, for any such
conflicts, violations, breaches, defaults or other occurrences which would not
prevent or delay the performance by such Shareholder of its obligations under
this Agreement.

                  (b) The execution and delivery of this Agreement by such
Shareholder does not, and the performance of this Agreement by such Shareholder
shall not, require any consent, approval, authorization or permit of, or filing
with or notification to, any governmental entity except for applicable

grant a proxy or power of attorney with respect to the Shares held of record or

effective with respect to Additional Shares without action by any Person
immediately upon the acquisition by a Shareholder of record or Beneficial
Ownership of such Additional Shares.

to file promptly after the Registration Statement (as defined in the Merger
Agreement) is declared effective and use its reasonable commercial efforts to

instrument in writing signed by the parties hereto.

illegal or incapable of being enforced, the parties hereby shall negotiate in
good faith to modify this Agreement so as to effect the original intent of the
parties as closely as possible to the fullest extent permitted by applicable law
in a mutually acceptable manner in order that the terms of this Agreement remain
as originally contemplated.
