To Our Clients:

    Enclosed for your consideration are the Offer to Purchase, dated May 11,
2000 (the "Offer to Purchase"), and the related Letter of Transmittal (which, as
amended from time to time, together constitute the "Offer") in connection with
the Offer by FIS Acquisition Corp., a New Jersey corporation (the "Purchaser")
and a wholly owned subsidiary of Automatic Data Processing, Inc., a Delaware
corporation ("Parent"), to purchase all outstanding shares of common stock, no
par value (the "Shares") of Cunningham Graphics International, Inc., a New
Jersey corporation (the "Company"), at a price of $22.00 per Share, net to the
seller in cash, without interest thereon, upon the terms and subject to the
conditions set forth in the Offer to Purchase. Also enclosed is the letter to
shareholders of the Company from the President and Chief Executive Officer of
the Company accompanied by the Company's Solicitation/ Recommendation Statement
on Schedule 14D-9. Unless the context indicates otherwise, as used herein,
shareholders shall mean holders of Shares.

    Shareholders whose certificates evidencing Shares (the "Share Certificates")
are not immediately available or who cannot deliver their Share Certificates and
all other documents required by the Letter of Transmittal to Wilmington Trust
Company (the "Depositary") prior to the Expiration Date (as defined in the Offer
to Purchase) or who cannot complete the procedure for delivery by book-entry
transfer to the Depositary's account at the Book-Entry Transfer Facility (as
defined in Section 2 of the Offer to Purchase) on a timely basis and who wish to
tender their Shares must do so pursuant to the guaranteed delivery procedure
described in Section 2 of the Offer to Purchase. See Instruction 2 of the Letter
of Transmittal. Delivery of documents to the Book-Entry Transfer Facility in
accordance with the Book-Entry Transfer Facility's procedures does not
constitute delivery to the Depositary.

    THIS MATERIAL IS BEING SENT TO YOU AS THE BENEFICIAL OWNER OF SHARES HELD BY
US FOR YOUR ACCOUNT BUT NOT REGISTERED IN YOUR NAME. WE ARE THE HOLDER OF RECORD
OF SHARES HELD BY US FOR YOUR ACCOUNT. A TENDER OF SUCH SHARES CAN BE MADE ONLY
BY US AS THE HOLDER OF RECORD AND PURSUANT TO YOUR INSTRUCTIONS. THE LETTER OF
TRANSMITTAL IS BEING FURNISHED TO YOU FOR YOUR INFORMATION ONLY AND CANNOT BE
USED BY YOU TO TENDER SHARES HELD BY US FOR YOUR ACCOUNT.

    We request instructions as to whether you wish to have us tender on your
behalf any or all of the Shares held by us for your account upon the terms and
subject to the conditions set forth in the Offer to Purchase.

    Your attention is directed to the following:

        1.  The offer price is $22.00 per Share, net to you in cash, without
    interest thereon.

        2.  The Board of Directors of the Company has unanimously approved the
    Merger Agreement (as defined below), the Offer and the Merger (as defined
    below), determined that the Offer and the Merger are advisable

    and fair to, and in the best interests of, the shareholders of the Company
    and unanimously recommends that the shareholders of the Company accept the
    Offer and tender their Shares pursuant to the Offer.

        3.  The Offer and withdrawal rights will expire at 12:00 midnight, New
    York City time, on June 8, 2000, unless the Offer is extended.

        4.  The Offer is being made for all outstanding Shares.

        5.  The Offer is being made pursuant to the Agreement and Plan of Merger
    dated as of May 2, 2000 (the "Merger Agreement"), among the Purchaser,
    Parent and the Company pursuant to which, following the consummation of the
    Offer and the satisfaction or waiver of certain conditions, the Purchaser
    will be merged with and into the Company, with the Company surviving the
    merger as a wholly owned subsidiary of Parent (the "Merger"). In the Merger,
    each outstanding Share (other than Shares owned by Parent, the Purchaser or
    any subsidiary or affiliate of Parent, the Purchaser or by the Company) will
    be converted into the right to receive $22.00 per Share, net to the seller
    in cash, without interest, as set forth in the Merger Agreement and
    described in the Offer to Purchase.

        6.  The Offer is conditioned upon, among other things, (i) there being
    validly tendered and not properly withdrawn prior to the expiration of the
    Offer that number of Shares which, when added to the Shares beneficially
    owned by the Purchaser or Parent, represents at least a majority of the
    total number of Shares outstanding on a fully diluted basis on the date of
    purchase and (ii) the expiration or termination of any applicable waiting
    period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as
    amended. See Section 14 of the Offer to Purchase.

    Tendering shareholders will not be obligated to pay brokerage fees or
commissions or, except as set forth in Instruction 6 of the Letter of
Transmittal, stock transfer taxes on the purchase of Shares by the Purchaser
pursuant to the Offer.

    The Offer is made solely by the Offer to Purchase and the related Letter of
Transmittal and any supplements or amendments thereto and is being made to all
holders of Shares. The Offer is not being made to (nor will tenders be accepted
from or on behalf of) holders of Shares in any jurisdiction in which the making
of the Offer or the acceptance thereof would not be in compliance with the
securities, blue sky or other laws of such jurisdiction. Neither the Purchaser
nor Parent is aware of any jurisdiction in which the making of the Offer or the
acceptance thereof would not be in compliance with the laws of such
jurisdiction. To the extent the Purchaser or Parent becomes aware of any state
law that would limit the class of offerees in the Offer, the Purchaser will
amend the Offer and, depending on the timing of such amendment, if any, will
extend the Offer to provide adequate dissemination of such information to such
holders of shares prior to the expiration of the Offer. In any jurisdiction the
securities, blue sky or other laws of which require the Offer to be made by a
licensed broker or dealer, the Offer is being made on behalf of the Purchaser by
Lehman Brothers Inc. or one or more registered brokers or dealers licensed under
the laws of such jurisdiction.

    If you wish to have us tender any or all of your Shares, please so instruct
us by completing, executing and returning to us the instruction form contained
in this letter. An envelope in which to return your instructions to us is
enclosed. If you authorize the tender of your Shares, all such Shares will be
tendered unless otherwise specified on the instruction form contained in this
letter. YOUR INSTRUCTIONS SHOULD BE FORWARDED TO US IN AMPLE TIME TO PERMIT US
TO SUBMIT A TENDER ON YOUR BEHALF PRIOR TO THE EXPIRATION OF THE OFFER.

    In all cases, payment for Shares accepted for payment pursuant to the Offer
will be made only after timely receipt by the Depositary of (i) certificates for
(or a timely Book-Entry Confirmation (as defined in the Offer to Purchase) with
respect to such Shares, (ii) a Letter of Transmittal (or a facsimile thereof),
properly completed and duly executed, with any required signature guarantees,
or, in the case of a book-entry transfer effected pursuant to the procedures
described in Section 2 of the Offer to Purchase, an Agent's Message (as defined
in the Offer to Purchase), and (iii) any other documents required by the Letter
of Transmittal. Accordingly, tendering shareholders may be paid at different
times depending upon when certificates for Shares or Book-Entry Confirmations
with respect to Shares are actually received by the Depositary. THE PURCHASER
SHALL NOT HAVE ANY OBLIGATION TO PAY INTEREST ON THE PURCHASE PRICE FOR TENDERED
SHARES, WHETHER OR NOT THE PURCHASER EXERCISES ITS RIGHT TO EXTEND THE OFFER.

    If holders of Shares wish to tender Shares, but it is impracticable for them
to forward their Share Certificates or other required documents to the
Depositary prior to the Expiration Date or to comply with the procedures for
book-entry transfer on a timely basis, a tender may be effected by following the
guaranteed delivery procedures specified under Section 2 of the Offer to
Purchase.
