To Our Clients:

     Enclosed for your consideration is a Prospectus, dated February __, 1998
(as the same may be amended from time to time, the "Prospectus"), and a Letter
of Transmittal (the "Letter of Transmittal") relating to the offer by Newpark
Resources, Inc. (the "Company") to exchange (the "Exchange Offer") its 8 5/8%
Senior Subordinated Notes due 2007, Series B (the "Exchange Notes"), for a like
principal amount of its 8 5/8% Senior Subordinated Notes due 2007, Series A
(the "144A "Notes").  The Exchange Offer is subject to certain customary
conditions.  See "The Exchange Offer" in the Prospectus.

     The material is being forwarded to you as the beneficial owner of 144A
Notes carried by us for your account or benefit, but not registered in your
name.  An exchange of such 144A Notes only may be made by us as the registered
holder and pursuant to your instructions.

     Accordingly, we request instructions as to whether you wish us to exchange
any or all of the 144A Notes held by us for your account or benefit pursuant to
the terms and conditions set forth in the Prospectus and Letter of Transmittal.
We urge you to read carefully the Prospectus and Letter of Transmittal before
instructing us to exchange your 144A Notes.

     Your instructions to us should be forwarded as promptly as possible in
order to permit us to exchange 144A Notes on your behalf in accordance with the
provisions of the Exchange Offer.  The Exchange Offer expires at 5:00 p.m., New
York City time, on March __, 1998 (the "Initial Expiration Date"), unless
extended.  With respect to the Exchange Offer, "Expiration Date" means the
Initial Expiration Date, or if the Exchange Offer is extended, the latest time
and date to which the Exchange Offer is so extended by the Company.  Tender of
144A Notes may be withdrawn at any time prior to 5:00 p.m., New York City time,
on the Expiration Date.  So long as we continue to be the registered holder of
144A Notes beneficially owned by you, a withdrawal of tendered 144A Notes only
may be made by us in accordance with the procedures set forth in the Prospectus
and in Instruction 14 of the Letter of Transmittal.

     Your attention is directed to the following:

          1.  The Exchange Offer is for the exchange of $1,000 principal amount
     of Exchange Notes for each $1,000 principal amount of tendered 144A
     Notes.  The Exchange Notes are identical in all material respects to the
     144A Notes, except that the issuance of the Exchange Notes has been
     registered under the Securities Act of 1933, as amended, and therefore the
     Exchange Notes will not bear legends restricting their transfer and will
     not contain certain provisions providing for an increase in the interest
     rate payable on the 144A Notes under certain circumstances relating to the
     timing of the Exchange Offer.
     

 
    
          2.  The Exchange Offer and withdrawal rights will expire at 5:00 p.m.,
     New York City time, on March __, 1998, unless extended.

          3.  144A Notes may be tendered only in integral multiples of $1,000.

          4.  Any transfer taxes incident to the transfer of Notes from the
     tendering holder to the Company will be paid by the Company, except as
     otherwise provided in the Prospectus and in Instruction 7 of the Letter of
     Transmittal.

     The Exchange Offer is not being made to, nor will exchanges be accepted
from or on behalf of, holders of 144A Notes residing in any jurisdiction in
which the making of the Exchange Offer or acceptance thereof would not be in
compliance with the laws of such jurisdiction.

     If you wish us to exchange any or all of your 144A Notes held by us for
your account or benefit, please so instruct us by completing, executing and
returning to us the instruction form that appears below.
