To Our Clients:

  Enclosed for your consideration is the Offer to Purchase, dated August 7,
2000, and the related Letter of Transmittal (which, together with the Offer to
Purchase and any amendments or supplements thereto, collectively constitute
the "Offer") in connection with the offer by Securitas Acquisition
Corporation, a Delaware corporation ("Purchaser") and an indirect wholly owned
subsidiary of Securitas AB, a joint stock company organized under the laws of
Sweden ("Parent"), to purchase for cash all shares of Common Stock, par value
$0.01 per share (the "Company Common Stock"), including the associated rights
to purchase Series A Participating Cumulative Preferred Stock, issued under
the Rights Agreement (as defined in Section 1.2 of the Agreement and Plan of
Merger) (the "Rights" and together with the Company Common Stock, the
"Shares"), of Burns International Services Corporation, a Delaware corporation
(the "Company"), at a price of $21.50 per share of Company Common Stock or
such higher price as may be paid in the Offer (the "Per Share Amount"), net to
the seller in cash, upon the terms and subject to the conditions set forth in
the Offer to Purchase and in the related Letter of Transmittal enclosed
herewith. Holders of Shares whose certificates for such shares (the "Share
Certificates") are not immediately available or who cannot deliver their Share
Certificates and all other required documents to The Bank of New York, the
Depositary, on or prior to the Expiration Date (as defined in the Offer to
Purchase), or who cannot complete the procedure for delivery by book-entry
transfer on a timely basis, must tender their shares according to the
guaranteed delivery procedures set forth in Section 3 of the Offer to
Purchase.

  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 enclosed Letter of Transmittal is furnished to you for
your information only and cannot be used by you to tender Shares held by us
for your account.

  Accordingly, 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.



  Your attention is directed to the following:

    1. The offer price is $21.50 per Share, net to you in cash, without
  interest.

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

    3. The Board of Directors of the Company has approved the Merger
  Agreement (as defined in the Offer to Purchase) and the transactions
  contemplated thereby, including the Offer and the Merger (as defined in the
  Offer to Purchase), and has determined that the Offer and the Merger are
  fair to, and in the best interests of, the Company's stockholders and
  recommends that the stockholders accept the Offer and tender their Shares
  pursuant to the Offer.

    4. The Offer and withdrawal rights expire at 12:00 Midnight, New York
  City time, on September 1, 2000, unless the Offer is extended.

    5. The Offer is conditioned upon, among other things, there being validly
  tendered and not withdrawn prior to the Expiration Date of the Offer (as
  defined in the Offer to Purchase) at least the number of Shares that shall
  constitute a majority of the then outstanding Shares on a fully diluted
  basis on the date such Shares are accepted for payment and the expiration
  or termination of any applicable waiting periods under the Hart-Scott-
  Rodino Antitrust Improvements Act of 1976, as amended. The Offer is also
  subject to the other conditions set forth in the Offer to Purchase. See
  Section 14 of the Offer to Purchase.

    6. Tendering stockholders will not be obligated to pay brokerage fees or
  commissions or, except as otherwise provided in Instruction 6 of the Letter
  of Transmittal, stock transfer taxes with respect to the purchase of Shares
  by Purchaser pursuant to the Offer.

  The Offer is being made solely by the Offer to Purchase and the related
Letter of Transmittal and is being made to all holders of Shares. Purchaser is
not aware of any jurisdiction where the making of the Offer is prohibited by
administrative or judicial action pursuant to any valid state statute. If
Purchaser becomes aware of any valid state statute prohibiting the making of
the Offer or the acceptance of Shares pursuant thereto, Purchaser will make a
good faith effort to comply with such state statute. If, after such good faith
effort, Purchaser cannot comply with such state statute, the Offer will not be
made to (nor will tenders be accepted from or on behalf of) the holders of
Shares in such state. In any jurisdiction in which the securities, blue sky or
other laws require the Offer to be made by a licensed broker or dealer, the
Offer will be deemed to be made on behalf of Purchaser by 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 held by us for your
account, please so instruct us by completing, executing and returning to us
the instruction form contained in the reverse side of 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 by your instructions on the reverse side of 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.
