your instructions. The enclosed Letter of Transmittal is furnished to you for
your information only and cannot be used to tender Old Notes.

         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 subject to
the conditions set forth in the Prospectus and the Letter of Transmittal.

         To ensure the Exchange Offer and the tender of Old Notes is in
compliance with state jurisdictional requirements you must complete the enclosed
client information sheet (the "Client Information Sheet").

         Your instructions to us and the Client Information Sheet should be
forwarded as promptly as possible in order to permit us to tender your Old Notes
on your behalf in accordance with the provisions of the Prospectus and the
Letter of Transmittal. The Exchange Offer will expire at 5:00 p.m., New York
City time, on        , 2001, unless extended by Tri-Union. Old Notes properly
tendered may be withdrawn at any time prior to the Expiration Date.

         The Exchange Offer is not conditioned upon any minimum number of Old
Notes being tendered.

         Pursuant to the Letter of Transmittal, each holder of Old Notes must
represent to Tri-Union that:

         o        the New Notes to be acquired by such holder pursuant to the
                  Exchange Offer are being acquired in the ordinary course of
                  business of the holder;

         o        such holder is not participating, does not intend to
                  participate, and has no arrangement or understanding with any
                  person to participate, in the distribution of the New Notes;

         o        such holder is not an "affiliate," as defined under Rule 405
                  of the Securities Act, of Tri-Union;

         o        such holder acknowledges that any person who is a
                  broker-dealer registered under the Securities Exchange Act of
                  1934, as amended, or who tenders Old Notes in the Exchange
                  Offer for the purpose of participating in a distribution of
                  the New Notes must comply with the registration and prospectus
                  delivery requirements of the Securities Act in connection with
                  any secondary resale


   3



                  transaction and cannot rely on the position of the staff of
                  the Securities and Exchange Commission enunciated in its
                  series of interpretive "no-action" letters with respect to
                  exchange offers;

         o        if the holder is a broker-dealer that will receive New Notes
                  for its own account in exchange for Old Notes, it must
                  represent that the Old Notes to be exchanged for New Notes
                  were acquired as a result of market-making activities or other
                  trading activities and must acknowledge that it will deliver a
                  prospectus meeting the requirements of the Securities Act in
                  connection with any resale of New Notes received in respect of
                  such Old Notes pursuant to the Exchange Offer; however, by so
                  acknowledging and by delivering a prospectus in connection
                  with the exchange of Old Notes, the holder will not be deemed
                  to admit that it is an "underwriter" within the meaning of the
                  Securities Act; and

         o        if the holder is not a broker-dealer, it must represent that
                  it is not engaged in, and does not intend to engage in, a
                  distribution of New Notes.

         The enclosed "Instruction to Registered Holder or DTC Participant from
Beneficial Owner" form contains an authorization by you, as the beneficial owner
of Old Notes, for us to make the foregoing representations on your behalf.

         We urge you to read the enclosed Letter of Transmittal in conjunction
with the Exchange Offer carefully before instructing us to tender your Old
Notes.

         Your attention is directed to the following:

         o        the Exchange Offer is described in and subject to the terms
                  and conditions set forth in the Prospectus;

         o        subject to the terms and conditions of the Exchange Offer,
                  Tri-Union will accept for exchange on the Expiration Date all
                  Old Notes properly tendered and will issue New Notes promptly
                  after such acceptance;

         o        if you desire to tender any Old Notes pursuant to the Exchange
                  Offer, we must receive your instructions and the Client
                  Information Sheet in ample time to permit us to effect a
                  tender of the Old Notes on your behalf prior to the Expiration
                  Date; and

         o        any brokerage fees, commissions or transfer taxes will be
                  borne by Tri-Union, except as otherwise provided in
                  Instruction 6 of the Letter of Transmittal.

         If you wish to tender any or all of the Old Notes held by us for your
account, please so instruct us by completing, executing, detaching and returning
to us the instruction form attached hereto. If you authorize the tender of your
Old Notes, all such Old Notes will be tendered unless otherwise specified on the

   4



time to permit us to submit a tender on your behalf on or prior to the
Expiration Date. The specimen 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.

         Tri-Union is not aware of any jurisdiction in which the making of the
Exchange Offer or the tender of Old Notes in connection therewith would not be
in compliance with the laws of such jurisdiction. However, to further ensure the
making of the Exchange Offer and the tender of Old Notes is in compliance with
jurisdictional requirements, please complete, execute, detach and return the
enclosed Client Information Sheet. If Tri-Union becomes aware of any
jurisdiction in which the making of the Exchange Offer would not be in
compliance with such laws, Tri-Union will make a good faith effort to comply
with any such laws or seek to have such laws declared inapplicable to the
Exchange Offer. If, after such good faith effort, Tri-Union cannot comply with
any such laws, the Exchange Offer will not be made to the Registered Holders
residing in such jurisdiction.
