To Our Clients:
 
     We are enclosing herewith a Prospectus dated                     , 1998 of
MSX International, Inc., a Delaware corporation (the "Company"), and a related
Letter of Transmittal (which together constitute the "Exchange Offer") relating
to the offer by the Company to exchange its 11 3/8% Senior Notes due 2008 (the
"Exchange Notes"), pursuant to an offering registered under the Securities Act
of 1933, as amended (the "Securities Act"), for a like principal amount of its
issued and outstanding 11 3/8% Senior Notes due 2008 (the "Old Notes") upon the
terms and subject to the conditions set forth in the Exchange Offer.
 
     PLEASE NOTE THAT THE EXCHANGE OFFER WILL EXPIRE AT 5:00 P.M., NEW YORK CITY
TIME, ON                     , 1998, UNLESS EXTENDED.
 
     The Exchange Offer is not conditioned upon any minimum number of Old Notes
being tendered.
 
     We are the holder of record and/or participant in the book-entry transfer
facility of Old Notes held by us for your account. A tender of such Old Notes
can be made only by us as the record holder and/or participant in the book-entry
transfer facility and pursuant to your instructions. The Letter of Transmittal
is furnished to you for your information only and cannot be used by you to
tender Old Notes held by us for your account.
 
     We request instructions as to whether you wish to tender any or all of the
Old Notes held by us for your account pursuant to the terms and conditions of
the Exchange Offer. We also request that you confirm that we may on your behalf
make the representations contained in the Letter of Transmittal.
 
     Pursuant to the Letter of Transmittal, each holder of Old Notes will
represent to the Company that (i) it is not an "affiliate" of the Company within
the meaning of Rule 405 under the Securities Act, (ii) any Exchange Notes to be
received by it are being acquired in the ordinary course of business, and (iii)
it has no arrangement or understanding with any person to participate in a
distribution (within the meaning of the Securities Act) of such Exchange Notes.
Each broker-dealer that receives Exchange Notes for its own account in exchange
for Old Note, where such Old Notes were acquired as the result of market-making
activities, must acknowledge that it will deliver a prospectus in connection
with any resale of such Exchange Notes. The Letter of Transmittal states that by
so acknowledging and delivering a prospectus, the broker-dealer will not be
deemed to admit that it is an "underwriter" within the meaning of the Securities
Act.
                                          Very truly yours,
