                PLEASE READ ACCOMPANYING INSTRUCTIONS CAREFULLY
 
Ladies and Gentlemen:
 
  Subject to the terms and conditions of the Exchange Offer, the undersigned
hereby tenders to Terra Industries Inc., a Maryland corporation (the
"Company"), the principal amount of Notes indicated above.
 
  Subject to and effective upon the acceptance for exchange of the principal
amount of Notes tendered in accordance with this Letter of Transmittal, the
undersigned sells, assigns and transfers to, or upon the order of, the Company
all right, title and interest in and to the Notes tendered hereby. The
undersigned hereby irrevocably constitutes and appoints the Exchange Agent its
agent and attorney-in-fact (with full knowledge that the Exchange Agent also
acts as the agent of the Company) with respect to the tendered Notes with the
full power of substitution to (i) present such Notes and all evidences of
transfer and authenticity to, or transfer ownership of, such Notes on the
account books maintained by the Book-Entry Transfer Facility to, or upon, the
order of, the Company, (ii) deliver certificates for such Notes to the Company
and deliver all accompanying evidences of transfer and authenticity to, or upon
the order of, the Company and (iii) present such Notes for transfer on the
books of the Company and receive all benefits and otherwise exercise all rights
of beneficial ownership of such Notes, all in accordance with the terms of the
Exchange Offer.
 
  The undersigned hereby represents and warrants that the undersigned has full
power and authority to tender, sell, assign and transfer the Notes tendered
hereby and that the Company will acquire good, valid and unencumbered title
thereto, free and clear of all liens, restrictions, charges and encumbrances
and not subject to any adverse claims, when the same are acquired by the
Company. The undersigned hereby further represents that any Exchange Notes
acquired in exchange for Notes tendered hereby will have been acquired in the
ordinary course of business of the person receiving such Exchange Notes,
whether or not such person is the undersigned, that neither the undersigned nor
any other such person has any arrangement or understanding with any person to
participate in the distribution (within the meaning of the Securities Act) of
such Exchange Notes and that neither the undersigned nor any such other person
is an "affiliate," as defined in Rule 405 under the Securities Act of the
Company nor a broker-dealer tendering notes acquired directly from the Company
for its own account. In addition, the undersigned and any such person
acknowledge that (a) any person participating the Exchange Offer for the
purpose of distributing the Exchange Notes must, in the absence of an exemption
therefrom, comply with the registration and prospectus delivery requirements of
the Securities Act in connection with a secondary resale of the Exchange Notes
and cannot rely on the position of the staff of the Commission enunciated in
no-action letters and (b) failure to comply with such requirements in such
instance could result in the undersigned or such person incurring liability
under the Securities Act for which the undersigned or such person is not
indemnified by the Company. The undersigned will, upon request, execute and
deliver any additional documents deemed by the Exchange Agent or the Company to
be necessary or desirable to complete the assignment, transfer and purchase of
the Notes tendered hereby. If the undersigned is not a broker-dealer, the
undersigned represents that it is not engaged in and does not intend to engage
in, a distribution of Exchange Notes. If the undersigned is a broker-dealer
that will receive Exchange Notes for its own account in exchange for Notes that
were acquired as a result of market-making activities or other trading
activities, it acknowledges that it will deliver a prospectus meeting the
requirements of the Securities Act in connection with any resale of such
Exchange Notes; however, by so acknowledging and by delivering a prospectus,
the undersigned will not be deemed to admit that it is an "underwriter" within
the meaning of the Securities Act.
 
  For purposes of the Exchange Offer, the Company shall be deemed to have
accepted validly tendered Notes when, as and if the Company has given oral or
written notice thereof to the Exchange Agent.
 
  If any Notes tendered herewith are not accepted for exchange pursuant to the
Exchange Offer for any reason, certificates for any such unaccepted Notes will
be returned, without expense, to the undersigned at the address shown below or
to a different address as may be indicated herein in Box 3 under "Special
Delivery Instructions" as promptly as practicable after the Expiration Date.
 
                                       4

 
  All authority conferred or agreed to be conferred by this Letter of
Transmittal shall survive the death, incapacity or dissolution of the
undersigned, and every obligation of the undersigned under this Letter of
Transmittal shall be binding upon the undersigned's heirs, personal
representative, successors and assigns.
 
  The undersigned understands that tenders of Notes pursuant to the procedures
described under the caption "Exchange Offer--Procedures for Tendering" in the
Prospectus and in the instructions hereto will constitute a binding agreement
between the undersigned and the Company upon the terms and subject to the
conditions of the Exchange Offer, subject only to withdrawal of such tenders on
the terms set forth in the Prospectus under the caption "Exchange Offer--
Withdrawal of Tenders."
 
  Unless otherwise indicated in Box 2 under "Special Registration
Instructions," please issue the certificates (or electronic transfers)
representing the Exchange Notes issued in exchange for the Notes accepted for
exchange and any certificates (or electronic transfers) for Notes not tendered
or not exchanged, in the name(s) of the undersigned. Similarly, unless
otherwise indicated in Box 3 under "Special Delivery Instructions," please send
the certificates, if any, representing the Exchange Notes issued in exchange
for the Notes accepted for exchange and any certificates for Notes not tendered
or not exchanged (and accompanying documents, as appropriate) to the
undersigned at the address shown below in the undersigned's signature(s). In
the event that both "Special Registration Instructions" and "Special Delivery
Instructions" are completed, please issue the certificates representing the
Exchange Notes issued in exchange for the Notes accepted for exchange in the
name(s) of, and return any certificates for Notes not tendered or not exchanged
to, the person(s) so indicated. The undersigned understands that the Company
has no obligation pursuant to the "Special Registration Instructions" and
"Special Delivery Instructions" to transfer any Notes from the name of the
registered Holder(s) thereof if the Company does not accept for exchange any of
the Notes so tendered.
 
  Holders who wish to tender their Notes and (i) whose Notes are not
immediately available or (ii) who cannot deliver the Notes, this Letter of
Transmittal or any other documents required hereby to the Exchange Agent prior
to the Expiration Date, may tender their Notes according to the guaranteed

Offer--Guaranteed Delivery Procedures." See Instruction 2 regarding the

                    FORMING PART OF THE TERMS AND CONDITIONS
                             OF THE EXCHANGE OFFER
 
  1. DELIVERY OF THIS LETTER OF TRANSMITTAL AND CERTIFICATES FOR NOTES OR BOOK-
ENTRY CONFIRMATIONS. Certificates representing the tendered Notes (or a
confirmation of book-entry transfer into the Exchange Agent's account with the
Book-Entry Transfer Facility for tendered Notes transferred electronically), as
well as a properly completed and duly executed copy of this Letter of
Transmittal (or facsimile thereof), a Substitute Form W-9 (or facsimile
thereof) and any other documents required by this Letter of Transmittal must be
received by the Exchange Agent at its address set forth herein prior to the
Expiration Date. The method of delivery of certificates for Notes and all other
required documents is at the election and sole risk of the tendering holder and
delivery will be deemed made only when actually received by the Exchange Agent.
If delivery is by mail, registered mail with return receipt requested, properly
insured, is recommended. As an alternative to delivery by mail, the holder may
wish to use an overnight or hand delivery service. In all cases, sufficient
time should be allowed to assure timely delivery. Neither the Company nor the
Exchange Agent is under an obligation to notify any tendering holder of the
Company's acceptance of tendered Notes prior to the consummation of the
Exchange Offer.
 
  2. GUARANTEED DELIVERY PROCEDURES. Holders who wish to tender their Notes but
whose Notes are not immediately available and who cannot deliver their
certificates for Notes (or comply with the procedures for book-entry transfer
prior to the Expiration Date), the Letter of Transmittal and any other
documents required by the Letter of Transmittal to the Exchange Agent prior to
the Expiration Date must tender their Notes according to the guaranteed
delivery procedures set forth below. Pursuant to such procedures:
 
    (i) such tender must be made by or through a firm which is a member of a
  registered national securities exchange or of the National Association of
  Securities Dealers, Inc., or a commercial bank or trust company having an
  office or correspondent in the United States, or is otherwise an "eligible
  guarantor institution" within the meaning of Rule 17Ad-15 under the
  Securities Exchange Act of 1934, as amended (an "Eligible Institution");
 
    (ii) prior to the Expiration Date, the Exchange Agent must have received
  from the holder and the Eligible Institution a properly completed and duly
  executed Notice of Guaranteed Delivery (by facsimile transmission, mail, or
  hand delivery) setting forth the name and address of the holder, the
  certificate number or numbers of the tendered Notes, and the principal
  amount of tendered Notes and stating that the tender is being made thereby
  and guaranteeing that, within three New York Stock Exchange trading days
  after the Expiration Date, the Letter of Transmittal (or facsimile
  thereof), together with the tendered Notes (or a confirmation of book-entry
  transfer into the Exchange Agent's account with the Book-Entry Transfer
  Facility for Notes transferred electronically) and any other required
  documents will be deposited by the Eligible Institution with the Exchange
  Agent; and
 
    (iii) such properly completed and executed Letter of Transmittal and
  certificates representing the tendered Notes in proper form for transfer
  (or a confirmation of book-entry transfer into the Exchange Agent's account
  with the Book-Entry Transfer Facility for Notes transferred electronically)
  must be received by the Exchange Agent within three New York Stock Exchange
  trading days after the Expiration Date.
 
  Any holder who wishes to tender Notes pursuant to the guaranteed delivery
procedures described above must ensure that the Exchange Agent receives the
Notice of Guaranteed Delivery relating to such Notes prior to the Expiration
Date. Failure to complete the guaranteed delivery procedures outlined above
will not, of itself, affect the validity or effect a revocation of any Letter
of Transmittal form properly completed and executed by a Holder who attempted
to use the guaranteed delivery person.
 
  3. TENDER BY HOLDER. Only a holder of Notes may tender such Notes in the
Exchange Offer. Any beneficial owner of Notes who is not the registered holder
and who wishes to tender should arrange with
 
                                       7

 
such holder to execute and deliver this Letter of Transmittal on such owner's
behalf or must, prior to completing and executing this Letter of Transmittal
and delivering such Notes, either make appropriate arrangements to register
ownership of the Notes in such owner's name or obtain a properly completed bond
power from the registered holder.
 
  4. PARTIAL TENDERS. Tenders of Notes will be accepted only in integral
multiples of $1,000 in principal amount. If less than the entire principal
amount of Notes is tendered, the tendering holder should fill in the principal
amount tendered in the column labeled "Aggregate Principal Amount Tendered" of
the box entitled "Description of 10 1/2% Senior Notes due 2005, Series A" (Box
1) above. The entire principal amount of Notes delivered to the Exchange Agent
will be deemed to have been tendered unless otherwise indicated. If the entire
principal amount of Notes is not tendered, Notes for the principal amount of
Notes not tendered and Exchange Notes exchanged for any Notes tendered will be
sent to the holder at his or her registered address (or transferred to the
account of the Book-Entry Facility designated above), unless a different
address (or account) is provided in the appropriate box on this Letter of
Transmittal, as soon as practicable following the Expiration Date.
 
  5. SIGNATURES ON THE LETTER OF TRANSMITTAL; BOND POWERS AND ENDORSEMENTS;
GUARANTEE OF SIGNATURES. If this Letter of Transmittal is signed by the
registered holder(s) of the Notes tendered herewith, the signatures must
correspond with the name(s) as written on the face of the tendered Notes
without alteration, enlargement, or any change whatsoever. If this Letter of
Transmittal is signed by a participant in the Book-Entry Transfer Facility, the
signature must correspond with the name as it appears on the security position
listing as the owner of the Notes.
 
  If any of the tendered Notes are owned of record by two or more joint owners,
all such owners must sign this Letter of Transmittal. If any tendered Notes are
held in different names on several Notes, it will be necessary to complete,
sign, and submit as many separate copies of the Letter of Transmittal documents
as there are names in which tendered Notes are held.
 
  If this Letter of Transmittal is signed by the registered holder, and
Exchange Notes are to be issued and any untendered or unaccepted principal
amount of Notes are to be reissued or returned to the registered holder, then
the registered holder need not and should not endorse any tendered Notes nor
provide a separate bond power. In any other case the registered holder must
either properly endorse the Notes tendered or transmit a properly completed
separate bond power with this Letter of Transmittal (in either case, executed
exactly as the name(s) of the registered holder(s) appear(s) on such Notes,
and, with respect to a participant in the Book-Entry Transfer Facility whose
name appears on a security position listing as the owner of Notes, exactly as
the name(s) of the participant(s) appear(s) on such security position
listings), with the signature(s) on the endorsement or bond power guaranteed by
an Eligible Institution unless such certificates or bond powers are signed by
an Eligible Institution.
 
  If this Letter of Transmittal or any Notes or bond powers are signed by
trustees, executors, administrators, guardians, attorneys-in-fact, officers of
corporations, or others acting in a fiduciary or representative capacity, such
persons should so indicate when signing and evidence satisfactory to the
Company of their authority to so act must be submitted with this Letter of
Transmittal.
 
  No signature guarantee is required if (i) this Letter of Transmittal is
signed by the registered holder(s) of the Notes tendered herewith (or by a
participant in the Book-Entry Transfer Facility whose appears on a security
position listing as the owner of the Tendered Notes) and the issuance of
Exchange Notes (and any Notes not tendered or not accepted) are to be issued
directly to such registered holder(s) (or, if signed by a participant in the
Book-Entry Transfer Facility, any Exchange Notes or Notes not tendered or not
accepted are to be deposited to such participant's account at such Book-Entry
Transfer Facility) and neither the "Special Delivery Instructions" (Box 3) nor
the "Special Registration Instructions" (Box 2) has been completed, or (ii)
such Notes are tendered for the account of an Eligible Institution. In all
other cases, all signatures on this Letter of Transmittal must be guaranteed by
an Eligible Institution.

  6. SPECIAL REGISTRATION AND DELIVERY INSTRUCTIONS. Tendering holders should
indicate, in the applicable box, the name and address (or account at the Book-
Entry Transfer Facility) in which the Exchange Notes and/or substitute Notes
for principal amounts not tendered or not accepted for exchange are to be sent
(or deposited), if different from the name and address or account of the person
signing this Letter of Transmittal. In the case of issuance in a different
name, the employer identification number or social security number of the
person named must also be indicated and the indicated and the tendering holders
should complete the applicable box.
 
  If no such instructions are given, the Exchange Notes (and any Notes not
tendered or not accepted) will be issued in the name of and sent to the holder
of the Notes or deposited at such holders' account at the Book-Entry Transfer
Facility.
 
  7. TRANSFER TAXES. Transfer taxes, if any, applicable to the sale and
transfer of Notes pursuant to the Exchange Offer will be payable by the
tendering holder.
 
  8. TAX IDENTIFICATION NUMBER. Federal income tax law requires that a holder
of any Notes which are accepted for exchange must provide the Company (as
payor) with its correct taxpayer identification number "TIN"), which, in the
case of a holder who is an individual is his or her social security number. If
the Company is not provided with the correct TIN, the holder may be subject to
a $50 penalty imposed by Internal Revenue Service. (If withholding results in
an over-payment of taxes, a refund may be obtained.) Certain holders
(including, among others, all corporations and certain foreign individuals) are
not subject to these backup withholding and reporting requirements. See the
enclosed "Guidelines for Certification of Taxpayer Identification Number on
Substitute Form W-9" for additional instructions.
 
  To prevent backup withholding, each tendering holder must provide such
holder's correct TIN by completing the Substitute Form W-9 set forth herein,
certifying that the TIN provided is correct (or that such holder is awaiting a
TIN), and that (i) the holder has not been notified by the Internal Revenue
Service that such holder is subject to backup withholding as a result of
failure to report all interest or dividends or (ii) the Internal Revenue
Service has notified the holder that such holder is no longer subject to backup
withholding. If the Notes are registered in more than one name or are not in
the name of the actual owner, see the enclosed "Guidelines for Certification of
Taxpayer Identification Number on Substitute Form W-9" for information on which
TIN to report.
 
  The Company reserves the right in its sole discretion to take whatever steps
are necessary to comply with the Company's obligation regarding backup
withholding.
 
  9. VALIDITY OF TENDERS. All questions as to the validity, form, eligibility
(including time of receipt), and acceptance of tendered Notes will be
determined by the Company, in its sole discretion, which determination will be
final and binding. The Company reserves the right to reject any and all Notes
not validly tendered or any Notes, the Company's acceptance of which would, in
the opinion of the Company or its counsel, be unlawful. The Company also
reserves the right to waive any conditions of the Exchange Offer or defects or
irregularities in tenders of Notes as to any ineligibility of any holder who
seeks to tender Notes in the Exchange Offer. The interpretation of the terms
and conditions of the Exchange Offer (including this Letter of Transmittal and
the instructions hereto) by the Company shall be final and binding on all
parties. Unless waived, any defects or irregularities in connection with
tenders of Notes must be cured within such time as the Company shall determine.
The Company will use reasonable efforts to give notification of defects or
irregularities with respect to tenders of Notes, but shall not incur any
liability for failure to give such notification.
 
  10. WAIVER OF CONDITIONS. The Company reserves the absolute right to amend,
waive, or modify specified conditions in the Exchange Offer in the case of any
tendered Notes.
 
  11. NO CONDITIONAL TENDER. No alternative, conditional, irregular, or
contingent tender of Notes on transmittal of this Letter of Transmittal will be
accepted.

  12. MUTILATED, LOST, STOLEN, OR DESTROYED NOTES. Any tendering holder whose
Notes have been mutilated, lost, stolen, or destroyed should contact the
Exchange Agent at the address indicated above for further instruction.
 
  13. REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES. Questions and requests for
assistance and requests for additional copies of the Prospectus may be directed
to the Exchange Agent at the address specified in the Prospectus. Holders may
also contact their broker, dealer, commercial bank, trust company, or other
nominee for assistance concerning the Exchange Offer.
 
  14. ACCEPTANCE OF TENDERED NOTES AND ISSUANCE OF EXCHANGE NOTES; RETURN OF
NOTES. Subject to the terms and conditions of the Exchange Offer, the Company
will accept for exchange all validly tendered Notes as soon as practicable
after the Expiration Date and will issue Exchange Notes therefor as soon as
practicable thereafter. For purposes of the Exchange Offer, the Company shall
be deemed to have accepted tendered Notes when, as and if the Company has given
written and oral notice thereof to the Exchange Agent. If any tendered Notes
are not exchanged pursuant to the Exchange Offer for any reason, such
unexchanged Notes will be returned, without expense, to the undersigned at the
address shown above (or credited to the undersigned's account at the Book-Entry
Transfer Facility designated above) or at a different address as may be
indicated under "Special Delivery Instructions."
 
  15. WITHDRAWAL. Tenders may be withdrawn only pursuant to the limited
withdrawal rights set forth in the Prospectus under the caption "Exchange
Offer--Withdrawal of Tenders."
