To Our Clients:

  Enclosed for your consideration is a Prospectus dated     , 2001 (the
"Prospectus") and a Letter of Transmittal (which together constitute the
"Exchange Offer") relating to the offer by Resolution Performance Products LLC
and RPP Capital Corporation (together, the "Issuers") to exchange their 13
1/2% Senior Subordinated Notes due 2010 (the "Exchange Notes") for an equal
principal amount of their outstanding 13 1/2% Senior Subordinated Notes due
2010 (the "Old Notes" and together with the Exchange Notes, the "Notes"). As
set forth in the Prospectus, the terms of the Exchange Notes are identical in
all material respects to the Old Notes, except that the Exchange Notes have
been registered under the Securities Act of 1933, as amended, and therefore
will not bear legends restricting their transfer and will not contain certain
provisions providing for the payment of liquidated damages to the holders of
the Old Notes under certain circumstances relating to the Exchange and
Registration Rights Agreement dated as of November 14, 2000 among the Issuers
Morgan Stanley & Co. Incorporated, J.P. Morgan Securities Inc. and Salomon
Smith Barney Inc. (the "Exchange and Registration Rights Agreement"). Old
Notes may be tendered only in integral multiples of $1,000.

  The enclosed material is being forwarded to you as the beneficial owner of
Old Notes carried by us for your account or benefit but not registered in your
name. An exchange of any Old Notes may only be made by us as the registered
Holder and pursuant to your instructions. Therefore, the Issuers urge
beneficial owners of Old Notes registered in the name of a broker, dealer,
commercial bank, trust company or other nominee to contact such Holder
promptly if they wish to exchange Old Notes in the Exchange Offer.

  Accordingly, we request instructions as to whether you wish us to exchange
any or all such Old 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 Old Notes.

  Your instructions to us should be forwarded as promptly as possible in order
to permit us to exchange Old 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            , 2001, unless extended. The term "Expiration
Date" shall mean 5:00 p.m., New York City time, on              , 2001, unless
the Exchange Offer is extended as provided in the Prospectus, in which case
the term "Expiration Date" shall mean the latest date and time to which the
Exchange Offer is extended. A tender of Old Notes may be withdrawn at any time
prior to 5:00 p.m., New York City time, on the Expiration Date.

Your attention is directed to the following:

    1. The Exchange Offer is for the exchange of $1,000 principal amount of
  the Exchange Notes for each $1,000 principal amount of the Old Notes, of
  which $200,000,000 aggregate principal amount was outstanding as of
              , 2000. The terms of the Exchange Notes are identical in all
  respects to the Old Notes, except that the Exchange Notes have been
  registered under the Securities Act of 1933, as amended, and therefore will
  not bear legends restricting their transfer and will not contain certain
  provisions providing for the payment of liquidated damages to the holders
  of the Old Notes under certain circumstances relating to the Exchange and
  Registration Rights Agreement.

    5. Any transfer taxes incident to the transfer of Old Notes from the
  tendering Holder to the Issuers will be paid by the Issuers, except as
  provided in the Prospectus and the Letter of Transmittal.

  The Exchange Offer is not being made to, nor will tenders be accepted from
or on behalf of, holders of Old Notes residing in any jurisdiction in which
the making of the Exchange Offer or the acceptance thereof would not be in
