ITEM 1. SECURITY AND SUBJECT COMPANY.
 
  The name of the subject company is Nu-West Industries, Inc., a Delaware
corporation (the "Company"), and the address of the principal executive
offices of the Company is 8400 East Prentice Avenue, Suite 1320, Englewood,
Colorado 80111. The title of the class of equity securities to which this
statement relates is the Voting Common Stock, par value $.01 per share (the
"Voting Common Stock").
 
ITEM 2. TENDER OFFER OF THE BIDDER.
 
  This statement relates to a cash tender offer by Agrium Acquisition
Corporation, a Delaware corporation (the "Purchaser"), a wholly owned
subsidiary of Agrium U.S. Inc., a Colorado corporation ("Agrium U.S."), a
wholly owned subsidiary of Agrium Inc., a Canadian corporation (the "Parent"),
described in a Tender Offer Statement filed pursuant to Section 14(d)(1) of
the Securities and Exchange Act of 1934, as amended (the "Exchange Act") on
Schedule 14D-1 (the "Schedule 14D-1"), dated August 16, 1995, to purchase all
of the outstanding shares of Voting Common Stock and the Nonvoting Common
Stock, par value $.01 per share (the "Nonvoting Common Stock" and, together
with the Voting Common Stock, the "Shares"), of the Company, at a purchase
price of $10.50 per Share (the "Offer Price") net to the seller in cash, upon
the terms and subject to the conditions set forth in the Offer to Purchase,
dated August 16, 1995 (the "Offer to Purchase"), and in the related Letter of
Transmittal (which with the Offer to Purchase, together with any amendments or
supplements, collectively constitute the "Offer"). Based on the information in
the Offer to Purchase, the principal executive offices of the Parent and the
Purchaser are located at 10333 Southport Road S.W., Suite 426, Calgary,
Alberta, Canada T2W 3X6.
 
  The Offer is being made pursuant to an Agreement and Plan of Merger dated as
of August 9, 1995 (the "Merger Agreement") among the Purchaser, the Parent and
the Company. The Merger Agreement provides, among other things, for the
commencement of the Offer by the Purchaser and further provides that, subject
to the satisfaction or waiver of certain conditions, the Purchaser will be
merged with and into the Company (the "Merger"), with the Company surviving
the Merger as a direct, wholly-owned subsidiary of Agrium U.S. (the "Surviving
Corporation"). In the Merger, each outstanding Share (other than Shares owned
by the Company or any subsidiary of the Company, the Parent, the Purchaser,
Agrium U.S. or any other subsidiary of the Parent, and Shares owned by
stockholders who shall have properly exercised their appraisal rights under
Delaware law) will be converted on the effective date of the Merger (the
"Effective Date") into the right to receive the Offer Price in cash, without
interest and less any required withholding taxes (the "Merger Consideration").
All other equity securities of the Company shall remain outstanding after the
Effective Date, subject to their respective terms and conditions. A copy of
the Merger Agreement is filed as Exhibit 1 hereto and is incorporated herein
by reference in its entirety. Certain provisions of the Merger Agreement are
described below in response to Item 3(b)(2).
 
ITEM 3. IDENTITY AND BACKGROUND.
 
  (a) The name and address of the Company, which is the person filing this
statement, are set forth in Item 1 above.
 
  (b)(1) Certain contracts, agreements, arrangements or understandings between
the Company and certain of its directors and executive officers are described
in the "Information Statement Pursuant to Section 14(f) of the Exchange Act
and Rule 14f-1 promulgated thereunder" (the "Information Statement"), that is
attached hereto as Annex II and incorporated herein by reference.
 
  Except as described in Annex II and as described in response to Item 3(b)(2)
below, to the knowledge of the Company, there exists on the date hereof no
material contract, agreement, arrangement or understanding and no actual or
potential conflict of interest between the Company or its affiliates and (i)
the Company's executive officers, directors or affiliates or (ii) the
executive officers, directors or affiliates of the Parent or the Purchaser.
 
  (b)(2) The following is a summary of certain provisions of the Merger
Agreement and the other agreements described under "Other Arrangements" below,
copies of which are filed as Exhibits hereto and are incorporated herein by
reference in their entirety. This summary is qualified in its entirety by
reference to such Exhibits.
 
THE MERGER AGREEMENT
 
  The following is a summary of the material terms of the Merger Agreement.
This summary is not a complete description of the terms and conditions thereof
and is qualified in its entirety by reference to the full text thereof. See
Exhibit 1 to this Schedule 14D-9.
 
 
                                       2
<PAGE>
 
  The Offer. The Merger Agreement provides that the Purchaser will commence
the Offer conditioned upon a sufficient number of Shares being properly
tendered and not withdrawn, which, when added together with any Shares owned
by the Parent and any of its subsidiaries or which the Purchaser and the
Parent have the right to acquire, will equal at least 60% of the Shares on a
fully diluted basis. The Merger Agreement provides that, without the prior
written consent of the Company, the Purchaser shall not decrease the Merger
Price, decrease the number of Shares being sought in the Offer, change the
form of consideration payable in the Offer, add additional conditions to the
Offer or make any other material change in the terms or conditions to the
Offer. After the time that the Purchaser's designees constitute at least a
majority of the Board and until the Effective Date, any amendment or
termination of the Merger Agreement, extension for the performance or waiver
of the obligations or other acts of the Purchaser or the Parent (except
pursuant to the Merger Agreement) or waiver of the Company's rights under the
Merger Agreement, which amendment, termination, extension or waiver would
adversely affect the stockholders, optionholders or employees of the Company,
will also require the approval of a majority (or such higher percentage as is
required under the By-laws of the Company) of the then serving directors, if
any, who were directors as of August 9, 1995 (the "Continuing Directors").
 
  The Merger Agreement provides that upon the acquisition of Shares pursuant
to the Offer, which, when added together with Shares owned by the Parent or
any of its direct or indirect subsidiaries, equal at least a majority of the
then outstanding shares of Voting Common Stock, the Company will fill any
vacancies and increase the size of its Board as necessary to enable the Parent
to designate at its option a majority of the Company's Board, and shall cause
the Purchaser's designees to be so elected and shall mail promptly the
information required by Section 14(f) of the Exchange Act and Rule 14f-1
promulgated thereunder.
 
  The Merger. The Merger Agreement provides that, subject to the terms and
conditions thereof, the Purchaser shall be merged with and into the Company,
which shall be the Surviving Corporation on the Effective Date. Pursuant to
the Merger, (x) the Certificate of Incorporation of the Company will be the
Certificate of Incorporation of the Surviving Corporation until thereafter
amended as provided by law, and (y) the By-laws of the Company will be the By-
laws of the Surviving Corporation until thereafter amended. The directors of
the Purchaser on the Effective Date will become the directors of the Surviving
Corporation until their respective successors are duly elected and qualified.
The officers of the Company on the Effective Date will continue as the
officers of the Surviving Corporation, to serve in accordance with the By-Laws
thereof until their respective successors are duly elected and qualified. The
Merger will have the effects set forth in the General Corporation Law of the
State of Delaware (the "DGCL").
 
  Conversion of Shares. The Merger Agreement provides that each outstanding
Share (other than Shares which are held by the Company as treasury shares, all
authorized and unissued Shares and any Shares owned by the Purchaser, the
Parent or any other direct or indirect subsidiary of the Parent and Shares
held by stockholders who exercise their statutory dissenters' rights as
described below) will be converted into the right to receive $10.50 net in
cash or such higher amount per Share as may be paid to any holder of Shares
pursuant to the Offer.
 
  The Merger Agreement provides that each issued and outstanding share of
capital stock of the Purchaser shall be converted into one validly issued,
fully paid and non-assessable share of Voting Common Stock of the Surviving
Corporation.
 
  The Merger Agreement provides that any issued and outstanding shares of
capital stock of the Company held by a Stockholder who has not voted in favor
of nor consented to the Merger and who complies with all the provisions of the
DGCL concerning the right of holders of such stock to dissent from the Merger
and require appraisal of their shares (a "Dissenting Stockholder"), shall not
be converted as described above but shall become, at the Effective Date, by
virtue of the Merger and without any further action, the right to receive such
consideration as may be determined to be due to such Dissenting Stockholder
pursuant to the DGCL; provided, however, that Shares outstanding immediately
prior to the Effective Date and held by a Dissenting Stockholder
 
                                       3
<PAGE>
 
who shall, after the Effective Date, withdraw his demand for appraisal or lose
his right of appraisal, in either case pursuant to the DGCL, shall be deemed
to be converted as of the Effective Date, into the right to receive the Merger
Price. The Merger Agreement provides that the Company will not, without the
prior written consent of the Purchaser, voluntarily make any payment with
respect to, or settle, offer to settle or otherwise negotiate, any demands by
Dissenting Stockholders.
 
  Stockholders' Meeting. Pursuant to the Merger Agreement, the Company has
agreed to take all action necessary in accordance with applicable law and its
Certificate of Incorporation and By-Laws to convene a meeting of the holders
of the Voting Shares as promptly as practicable after the expiration of the
Offer to consider and vote upon the adoption of the Merger Agreement, if such
stockholder approval is required by applicable law. The Company has agreed
that in the Proxy Statement with respect to the meeting, the Company will,
through its Board, recommend that the Company's stockholders adopt the Merger
Agreement, if such vote is required, except to the extent that the Board of
Directors will have withdrawn or modified its approval or recommendation of
the Tender Offer or the Merger Agreement after determining that it has a duty
in the proper discharge of its fiduciary responsibilities under applicable law
to withdraw or modify such approval or recommendation. The Parent has agreed
that at any stockholders' meeting, it will vote or cause all of the Shares
acquired pursuant to the Offer or otherwise by Purchaser or any affiliate of
Parent to be voted in favor of the Merger.
 
  Interim Operations of the Company. In the Merger Agreement, the Company has
agreed that, except as expressly provided in the Merger Agreement or consented
to in writing by the Parent or unless the failure to comply with any of the
following covenants results from actions by the Board which are approved by a
majority of the directors appointed by the Parent pursuant to the Merger
Agreement, prior to the Effective Date, (i) the businesses of the Company and
its subsidiaries will be conducted only in the ordinary and usual course of
business and (ii) the Company will not (A) (1) increase the compensation
payable to or to become payable to any director or executive officer, except
for increases in salary or wages payable or to become payable in the ordinary
course of business and consistent with past practice; (2) grant any severance
or termination pay (other than pursuant to the normal severance policy of the
Company or its subsidiaries as in effect on the date of the Merger Agreement)
to, or enter into or amend any employment or severance agreement with, any
director, officer or employee; (3) establish, adopt or enter into any new
employee benefit plan or arrangement; or (4) except as may be required by
applicable law and actions that are not inconsistent with the provisions of
the Merger Agreement, amend, or take any other actions (other than the
acceleration of vesting or waiving of performance criteria permitted pursuant
to the employee benefit plans upon a change in control of the Company) with
respect to, any of the Company's employee benefit plans; (B) declare or pay
any dividend on, or make any other distribution in respect of, outstanding
shares of capital stock, except for dividends by a subsidiary to the Company
or another subsidiary; (C) (1) except as described in the Company Disclosure
Schedule (as defined in the Merger Agreement), redeem, purchase or otherwise
acquire any shares of its or any of its subsidiaries' capital stock or any
securities or obligations convertible into or exchangeable for any shares of
its or its subsidiaries' capital stock (other than any such acquisition
directly from any wholly owned subsidiary of the Company in exchange for
capital contributions or loans to such subsidiary), or any options, warrants
or conversion or other rights to acquire any shares of its or its
subsidiaries' capital stock or any such securities or obligations (except in
connection with the exercise of outstanding stock options or warrants in
accordance with their terms); (2) effect any reorganization or
recapitalization; or (3) split, combine or reclassify any of its or its
subsidiaries' capital stock or issue or authorize or propose the issuance of
any other securities in respect of, in lieu of or in substitution for, shares
of its or its subsidiaries' capital stock; (D) (1) except as described in the
Company Disclosure Schedule, issue, deliver, award, grant or sell, or
authorize or propose the issuance, delivery, award, grant or sale (including
the grant of any security interests, liens, claims, pledges, limitations in
voting rights, charges or other encumbrances) of, any shares of any class of
its or its subsidiaries' capital stock (including shares held in treasury),
any securities convertible into or exercisable or exchangeable for any such
shares, or any rights, warrants or options to acquire any such shares (except
as permitted for the issuance of shares upon the exercise of stock options
outstanding as of the date of this Agreement) other than the conversion of
Voting Shares and Nonvoting Shares as provided in the Company's Certificate of
Incorporation, the exercise of warrants or the exercise of options under the
Company's stock option plans; or (2) amend or otherwise modify the terms of
any such rights, warrants or options the effect of which shall be to make such
terms more favorable to the holders
 
                                       4
<PAGE>
 
thereof; (E) acquire or agree to acquire, by merging or consolidating with, by
purchasing an equity interest in or a portion of the assets of, or by any
other manner, any business or any corporation, partnership, association or
other business organization or division thereof, or otherwise acquire or agree
to acquire any assets of any other person (other than the purchase of assets
from suppliers or vendors in the ordinary course of business) in each case
which are material, individually or in the aggregate, to the Company and its
subsidiaries, taken as a whole; (F) sell, lease, exchange, mortgage, pledge,
transfer or otherwise dispose of, or agree to sell, lease, exchange, mortgage,
pledge, transfer or otherwise dispose of, any of its material assets or any
material assets of any of its subsidiaries, except for dispositions in the
ordinary course of business and consistent with past practice; (G) adopt or
propose to adopt any amendments to its charter or By-Laws which would alter
the terms of its capital stock or would have an adverse impact on the
consummation of the transactions contemplated by the Merger Agreement; (H) (1)
change, in any material respect, any of its methods of accounting in effect at
June 30, 1995, or (2) make or rescind any express or deemed election relating
to taxes, settle or compromise any claim, action, suit, litigation,
proceeding, arbitration, investigation, audit or controversy relating to taxes
(except where the amount of such settlements or controversies, individually or
in the aggregate, would not have a Company Material Adverse Effect (as defined
in the Merger Agreement)), or change any of its methods of reporting income or
deductions for federal income tax purposes from those employed in the
preparation of the federal income tax returns for the taxable year ending June
30, 1994, except, in each case, as may be required by law or U.S. generally
accepted accounting principles; (I) other than as permitted by the Harris Loan
(as defined in the Merger Agreement), incur any material obligation for
borrowed money or purchase money indebtedness, whether or not evidenced by a
note, bond, debenture or similar instrument; (J) enter into any material
arrangement, agreement or contract with any third party (other than customers
in the ordinary course of business) that provides for an exclusive arrangement
with that third party or is substantially more restrictive on the Company or
substantially less advantageous to the Company than arrangements, agreements
or contracts existing on the date hereof unless such arrangement is entered
into in the ordinary course of business; or (K) agree in writing or otherwise
to do any of the foregoing.
 
  No Solicitation. In the Merger Agreement, the Company has agreed that the
Company will not solicit, initiate or knowingly encourage any inquiries,
discussions or negotiations with any person (other than the Purchaser or the
Parent) concerning any Acquisition Proposal or solicit, initiate or knowingly
encourage any effort or attempt by any other person to do, make or seek an
Acquisition Proposal or, unless required in order for the Board to comply with
its fiduciary responsibilities, with a view to pursuing an Acquisition
Proposal with such person, engage in discussions or negotiations with or
disclose any nonpublic information relating to the Company or any of its
subsidiaries to such person or authorize or permit any of the officers,
directors or employees of the Company or any of its subsidiaries or any
investment banker, financial adviser, attorney, accountant or other
representative retained by the Company or any of its subsidiaries to take any
such action. The Company has agreed to immediately communicate to the Parent
in writing the terms of any Acquisition Proposal which it may receive. As used
in the Merger Agreement, "Acquisition Proposal" means any bona fide written
proposal or offer from a third party (each an "Acquisition Proposal") relating
to (i) the acquisition or purchase of all or substantially all of the assets
of, or more than a 50% equity interest (including any Shares theretofore
acquired) in the Company, (ii) a merger, consolidation or similar business
combination with the Company or (iii) a tender or exchange offer for the
Company conditioned on ownership of more than 50% of the outstanding Shares
following such tender or exchange offer.
 
  Compensation and Benefits. Pursuant to the Merger Agreement, the Parent and
the Surviving Corporation have agreed for a period of two years from the
Effective Date, to honor in accordance with their terms the Company's employee
benefit plans, in each case to the extent the same have been delivered or made
available to the Purchaser for review, provided however that the Parent and
the Purchaser may amend or terminate any such plan at any time after the
Effective Date to the extent the amendment or termination is deemed to be
necessary or appropriate to comply with the requirements of applicable law.
 
  Representations and Warranties. In the Merger Agreement, the Company has
made customary representations and warranties to the Parent and the Purchaser
with respect to, among other things, its organization, authorization,
capitalization, potential conflicts, inventory, insurance, intellectual
property, financial
 
                                       5
<PAGE>
 
statements, public filings, employee benefit plans, defaults, information in
the Proxy Statement, compliance with laws, litigation, tax matters, real and
personal property, environmental matters, consents and approvals, undisclosed
liabilities and the absence of certain events. None of the representations and
warranties in the Merger Agreement will survive the Effective Date of the
Merger.

of the Voting Shares must have duly approved the Merger if required by

been enacted by the government of the United States or any state thereof that

to the transactions contemplated by this Agreement must have expired or been
terminated. The obligations of the Purchaser and the Parent to effect the
Merger shall be subject to the fulfillment at or prior to the Effective Date
of the following additional conditions: (i) the representations and warranties
of the Company set forth in the Merger Agreement must be true and correct in
all material respects on the Effective Date (or on such other date specified
in the Merger Agreement) with the same force and effect as though made on and
as of such date, and the Purchaser and the Parent must have received a
certificate to that effect from the Chief Executive Officer and the Treasurer
of the Company; (ii) all of the covenants and agreements of the Company to be
performed or complied with pursuant to the Merger Agreement prior to the
Effective Date must have been duly performed and complied with in all material
respects, and the Purchaser and the Parent must have received a certificate to
that effect from the Chief Executive Officer and the Treasurer of the Company;
(iii) holders of no more than 400,000 Shares, in the aggregate, shall have

the DGCL; (iv) all of the Continuing Directors of the Company on the Effective
Date must have resigned; (v) since the date of the Merger Agreement, there
shall have been no Company Material Adverse Effect (provided, however, that
certain IRS Notices of Proposed Adjustment will not be considered a Company

reserved for by the Company, no taxes shall be payable, or reasonably expected
by the Company to be payable, with respect to items or periods covered by the
returns and reports referred to in the Merger Agreement (whether or not shown
on or reportable on such returns or reports or with respect to any period
prior to the Effective Date), other than any such taxes which would not have a
Company Material Adverse Effect. The obligation of the Company to effect the
Merger shall be subject to the fulfillment at or prior to the Effective Date
of the following additional conditions: (i) the representations and warranties
of the Purchaser and the Parent set forth in the Merger Agreement shall be
true and correct in all material respects on the Effective Date (or on such
other date specified in the Merger Agreement) with the same force and effect
as though made on and as of such date, and the Company shall have received
certificates to that effect from the Chief Executive Officer and the Treasurer
of the Parent and the President of the Purchaser; (ii) all of the covenants
and agreements of the Purchaser and the Parent to be performed or complied
with pursuant to the Merger Agreement prior to the Effective Date shall have
been duly performed and complied with in all material respects, and the
Company shall have received certificates to that effect from the Chief
Executive Officer and the Treasurer of the Parent and the President of the
Purchaser.
 
  Termination. The Merger Agreement may be terminated at any time prior to the
Effective Date, whether before or after approval by the stockholders of the
Company, if required, (i) by mutual consent of the Parent and the Board; (ii)
by the Parent or the Company if the Merger shall not have been consummated on
or before December 15, 1995, which date may be extended by mutual agreement of
the boards of directors of the Company and the Parent; (iii) by the Company
if, prior to the Effective Date, the Company, its Board or its stockholders
shall receive an Acquisition Proposal and the Board determines that it has a
duty in the proper discharge of its fiduciary responsibilities under
applicable law to consider such other proposal or offer, and then such Board
either (A) accepts such proposal or offer, (B) recommends to the stockholders
acceptance of such proposal or
 
                                       6
<PAGE>
 
offer or (C) in the case of a tender or exchange offer, takes no position with
respect thereto and all conditions (other than terminating the Merger
Agreement) of such tender or exchange offer have been satisfied, in which
event the Merger Agreement shall be terminated without any liability to the
Company or the Company's Board as a result of such termination other than
payment of the (U.S.)$4,000,000 fee as set forth below; (iv) by the Parent
upon a breach of any material representation, warranty, covenant or agreement
on the part of the Company set forth in the Merger Agreement or if any
representation or warranty of the Company shall have become untrue and such
breach or untruth shall have caused a Company Material Adverse Effect; (v) by
the Company upon a breach of any material representation, warranty, covenant
or agreement on the part of the Parent set forth in this Agreement or if any
representation or warranty of the Parent shall have become untrue and such
breach or untruth shall have caused a Parent Material Adverse Effect (as
defined in the Merger Agreement). If the Merger Agreement is terminated
pursuant to (iii) above, the Company shall pay to Parent (U.S.)$4,000,000 in
cash. In the event of termination of the Merger Agreement by the Parent, the
Purchaser or the Company other than pursuant to (iii) above, there shall be no
liability under the Merger Agreement on the part of either the Company, the
Parent or the Purchaser or their respective officers or directors, with
certain exceptions as provided in the Merger Agreement including failure to
convene the meeting of Stockholders to vote on the Merger, certain
confidentiality provisions and a wilful breach of any representation,
warranty, covenant or agreement of the Purchaser, the Parent or the Company
contained in the Merger Agreement.
 
  Amendment. The Merger Agreement may be amended by the parties thereto, by
action taken by the respective Boards of Directors of the Purchaser, the
Parent and the Company, at any time before or after approval hereof by the
stockholders of the Company, but, after any such approval, if required, no
amendment shall be made which changes the Merger Price without the further
approval of such stockholders. The Merger Agreement may not be amended except
by an instrument in writing signed on behalf of each of the parties thereto.
 
  Timing. The exact timing and details for the Merger will depend upon legal
requirements and a variety of other factors, including the number of Shares
acquired by the Purchaser pursuant to the Offer. Although the Purchaser has
agreed to cause the Merger to be consummated on the terms set forth above,
there can be no assurance as to the timing of the Merger.
 
  Delaware Law. The Board has approved the Merger Agreement and the
transactions contemplated by it, including the Offer, the Merger Agreement and
the Merger for purposes of Section 203 of the DGCL. Accordingly, the
restrictions of Section 203 do not apply to the transactions contemplated by
the Offer and the Merger Agreement. Section 203 of the DGCL prevents an
"interested stockholder" (generally, a stockholder owning 15% or more of a
corporation's outstanding voting stock or an affiliate or associate of that
stockholder) from engaging in a "business combination" (defined to include a
merger and certain other transactions) with a Delaware corporation for a
period of three years following the date on which the stockholder became an
interested stockholder, unless (i) prior to that date, the corporation's board
of directors approved either the business combination or the transaction that
resulted in the stockholder becoming an interested stockholder, (ii) upon
consummation of the transaction that resulted in the stockholder becoming an
interested stockholder, the interested stockholder owned at least 85% of the
corporation's voting stock outstanding at the time the transaction commenced
(excluding shares owned by certain employee stock plans and persons who are
directors and also officers of the corporation) or (iii) on or subsequent to
that date, the business combination is approved by the corporation's board of
directors and authorized at an annual or special meeting of stockholders, and
not by written consent, by the affirmative vote of at least 66 2/3% of the
outstanding voting stock not owned by the interested stockholder. As described
above, Section 203 of the DGCL does not apply to the Offer or the Merger.

  Employment and Compensation Agreements. On December 1, 1994, the Company
entered into an employment agreement (the "Harlen Agreement") with Craig D.
Harlen to serve as the Company's President and Chief Executive Officer. The
Harlen Agreement provides for an annual base salary of $250,000 (which was
increased to $257,500 effective July 1, 1995) and automatically renews for
successive twelve month periods. The Harlen Agreement provides for severance
compensation equal to one year's base salary in the event of a termination
without cause, and severance compensation in the event of a termination by
reason of a change in control of the Company equal to three times the sum of
(i) Mr. Harlen's base salary at the time of the change in control, plus (ii)
the average of the performance bonus paid for the prior two fiscal years of
the Company. In no event, however, shall such severance compensation exceed
the amount that the Company may deduct for federal income tax purposes by
virtue of Section 280G of the Internal Revenue Code of 1986, as amended, or
any successor provision.
 
  On December 1, 1994, the Company entered into employment agreements with
each of H. Alan Dahlbach, Mark R. Sanders, Steven W. Gampp, Larry C. Dearing
and John D. Yokley. Each of these employment agreements provides for an annual
base salary and for severance compensation in the event of termination without
cause or by reason of a change in control, calculated in the same manner as
described above with respect to the Harlen Agreement. Effective July 1, 1995,
the employment agreements provide for annual base salaries in the aggregate
amount for all individuals of $816,790 per year. The compensation paid to each
of the employees under his employment agreement for the three fiscal years
ended June 30, 1995 are listed in the Summary Compensation Table included in
the Information Statement attached hereto as Annex II.
 
  The Harlen Agreement and each of the above described employment agreements
provides for certain payments in the event of death or disability. Also, each
such agreement contains non-competition and confidentiality provisions. For
purposes of the above agreements, a change in control occurs (i) if a person
other than the Company or Weiss, Peck & Greer, L.L.C. or its affiliates
acquires 40% or more of the outstanding
 
                                       8
<PAGE>
 
Voting Common Stock, (ii) if any merger, share exchange, issuance of capital
stock, tender offer or similar transaction results in the existing
stockholders owning fewer than 50% of the outstanding Voting Common Stock
after the transaction, (iii) upon a sale, lease or exchange of all or
substantially all of the Company's assets other than a sale/leaseback or
similar financing transaction or (iv) upon the adoption of a plan for the
liquidation or dissolution of the Company. A termination by reason of a change
in control of the Company includes constructive termination, as defined in the
agreements, including, for example, resignation following a substantial change
in duties, a reduction in salary or benefits, a relocation of the employee to
an office other than his current office, an uncured material breach by the
Company of the agreement or the failure of the executive and the Company or
its successor to negotiate a mutually agreeable amendment to the current
employment agreement or a new employment agreement within 90 days after the
change in control of the Company. For further disclosure relating to these
employment agreements, see Annex II.
 
  Compensation to Directors. The Company has agreed to pay Cecil D. Andrus an
annual retainer of $35,000 for his services as a non-employee director of the
Company during his current two-year term, which term ends in fiscal 1997.
Pursuant to the Merger Agreement, Governor Andrus has agreed to resign as a
director of the Company effective as of the Effective Date. The Company will
honor its agreement with Governor Andrus by the payment of the unpaid balance
of his retainer for the full two year term on or prior to the Effective Date.
No other director receives compensation for services as a director, but all
directors are reimbursed for travel and other expenses directly related to
their activities as directors. The Company also has a Company Non-Employee
Director Stock Option Plan, of which Governor Andrus is the sole participant.
See Annex II.
 
  Confidentiality Agreement. The Parent and the Company entered into a
Confidentiality Agreement, dated as of February 1, 1995 (the "Confidentiality
Agreement"), pursuant to which the Parent and its Representatives (as defined
in the Confidentiality Agreement) agreed to keep confidential certain business
and/or technical information of the Company to be furnished to them in
connection with the evaluation of a possible business combination or other
transaction. The Confidentiality Agreement also provides, among other things,
that, without the prior written consent of the Company, for a period of one
year neither the Parent nor its affiliates or agents will attempt to employ
any person who is at the time an employee of the Company.
 
  In addition, the Confidentiality Agreement provides that, for a period of
eighteen months, neither the Purchaser nor its affiliates will (or will assist
or encourage others to), without the prior written consent of the Company, (i)
acquire or agree to acquire, offer, seek or propose to acquire, or cause to be
acquired, ownership of any of the Company's assets or business or any voting
or debt securities or preferred stock issued by the Company or any rights or
options to acquire such ownership; (ii) seek or propose to influence or
control management or policies of the Company or to obtain representation on
the Company's Board of Directors, solicit or participate in the solicitation
of any proxies or consents with respect to any securities of the Company or
make any public announcement with respect to any of the foregoing; (iii) seek
to negotiate or influence the terms and conditions of employment of employees
of the Company; or (iv) enter into any discussions, negotiations, arrangements
or understandings with any third parties with respect to any of the foregoing.

WPG Corporate Development Associates II, L.P. Liquidating Trust, U/T/A dated
December 31, 1993 (the "Committing Stockholders" or the "WPG Affiliates") have
agreed to tender the 4,614,281 Shares owned by them in the Offer and have

voting securities of the Company owned by them ("Covered Shares") (A) in favor
of the Merger and adoption of the Merger Agreement and (B) against any
business combination proposal or other matter that may interfere or be
inconsistent with the Merger or the Merger Agreement (including, without
limitation, any Acquisition Proposal (as defined above in Item 3(b)(2) under
"No Solicitation")), at any meeting of stockholders of the Company (or consent
in lieu thereof) and any adjournment or adjournments thereof. The Committing
Stockholders have agreed not to sell or otherwise transfer or dispose of any
of the Covered Shares unless the following conditions are met: (i) prior
written notice of the Irrevocable Proxies is given to the transferee and the
transferee agrees that the shares transferred will remain subject to the
Irrevocable Proxies and, in connection therewith, executes and delivers to the
Parent a proxy covering such shares in form and substance satisfactory to the
Parent, which proxy shall be in substantially the form of the Irrevocable
Proxies or (ii) the transfer is to the Parent or its designee pursuant to the
Offer. The Irrevocable Proxies will terminate
 
                                       9
<PAGE>
 
automatically on the earliest to occur of (i) the Effective Date, (ii)
termination of the Merger Agreement pursuant to Section 9.1 thereof (including
a termination by the Company upon a determination by its Board of Directors
that it has a duty in the proper discharge of its fiduciary responsibilities
to accept, recommend or take no position with respect to an Acquisition
Proposal) or (iii) amendment of the Merger Agreement with respect to the Offer
Price to be received upon consummation of the Merger or the Offer. Peter B.
Pfister and Wesley W. Lang are currently directors of the Company and are also
principals of Weiss, Peck & Greer, L.L.C. See "Compensation Committee
Interlocks and Insider Participation" in the Information Statement attached
hereto as Annex II.
 
  Directors' and Officers' Indemnification. Pursuant to the Merger Agreement,
the Company must indemnify and hold harmless, and after the Effective Date,
the Parent and the Surviving Corporation must indemnify and hold harmless,
each present employee, agent, director or officer of the Company and the
Company's subsidiaries (the "Indemnified Parties") (a) with respect to any
losses, claims, damages, liabilities, costs and expenses, including reasonable
attorneys' and expert witness fees, arising out of or pertaining to any action
or omission occurring prior to the Effective Date (including any which arise
out of or pertain to the transactions contemplated by the Merger Agreement)
and (b) as provided in their respective charters or by-laws in effect at the
date hereof (to the extent consistent with applicable law), which provisions
will survive the Merger and will continue in full force and effect for a
period of not less than five years from the Effective Date. In the event any
claim or claims (a "Claim or Claims") are asserted or made pursuant to the
preceding sentence within such five-year period, all rights to indemnification
in respect of any such Claim or Claims shall continue until disposition of any
and all such Claims. In the event that a claim is asserted against any
Indemnified Party with respect to any matter to which the indemnities
contained in this section relate, the Indemnified Party shall give prompt
written notice to the Surviving Corporation setting forth in reasonable detail
the basis for such claim for indemnification. The Surviving Corporation has
the right, at its election, to take over the defense or settlement of such
claim at its own expense by giving prompt notice to that effect to the
Indemnified Party. If the Surviving Corporation has assumed the defense of any
Claim, the Surviving Corporation is authorized to consent to a settlement of,
or the entry of any judgment arising from, any such Claim, without the prior
written consent of the Indemnified Party; provided, however, that a condition
to any such settlement will be a complete release of the Indemnified Party
with respect to such Claim. If the Surviving Corporation does not, within
thirty days after receipt of the Indemnified Party's notice of Claim, (x) give
such notice to take over the defense of such Claim and proceed to defend the
Claim or (y) object to such Claim in writing to the Indemnified Party, then
the Indemnified Party will have the right to undertake the defense of such
Claim and the Surviving Corporation will pay to the Indemnified Party the
reasonable fees and expenses of its counsel. The Surviving Corporation will
not be liable for any settlement effected without its consent, which consent
will not be unreasonably withheld. The Indemnified Party will at all times
have the right, at its option and expense, to participate fully in, but not to
control, any such defense. Without limiting the foregoing, the Company and,
after the Effective Date, the Surviving Corporation, to the extent permitted
by applicable law, will periodically advance reasonable expenses as incurred
with respect to the foregoing to the fullest extent permitted under applicable
law provided the person to whom the expenses are advanced provides an
undertaking to repay such advances if it is ultimately determined that such
person is not entitled to indemnification. In the event that within five years
from the Effective Date the Surviving Corporation consolidates or merges with
or into any other person or transfers all or substantially all of its assets
to any person and such person surviving such consolidation or merger or to
which such assets have been transferred is not a Delaware corporation, the
Surviving Corporation will enter into an agreement pursuant to which such
person must agree to provide indemnification substantially equivalent to that
required of the Company hereunder.
 
ITEM 4. THE SOLICITATION OR RECOMMENDATION
 
  A. RECOMMENDATION OF THE BOARD OF DIRECTORS.
 
  The Board of Directors has unanimously approved the Merger Agreement and the
transactions contemplated thereby and determined that each of the Offer and
the Merger is fair to and in the best interests of the stockholders of the
Company. The Board of Directors recommends that all holders of Shares accept
the Offer and tender their Shares pursuant to the Offer.
 
                                      10
<PAGE>
 
  B. BACKGROUND; REASONS FOR THE RECOMMENDATION.
 
  In the Spring of 1994, following the completion of the recapitalization of
the Company in November 1993 and with fertilizer prices and demand steadily
improving, the Board of Directors of the Company began exploring alternatives
to enhance long-term stockholder value. On November 14, 1994, the Board of
Directors held a meeting, at which representatives of Kidder, Peabody & Co.
Incorporated ("Kidder, Peabody") were present, to discuss such alternatives,
including strategic relationships with other fertilizer producers, the sale or
merger of the Company, the formation of a joint venture or the continuation of
the Company as a stand-alone entity. The Board of Directors of the Company,
with the assistance of representatives of Kidder, Peabody, discussed the
possible process and timing for contacting potential acquirors.
 
  In December 1994, following the announcement of the sale of certain assets
of Kidder, Peabody and its affiliates to the parent company of PaineWebber
Incorporated ("PaineWebber"), the Board of Directors of the Company informed
PaineWebber that it intended to engage PaineWebber as its exclusive financial
advisor. PaineWebber was so engaged by letter agreement dated as of January
11, 1995.
 
  From mid-December 1994 through March 1995, pursuant to authorizations by the
Company, representatives of PaineWebber contacted twelve parties (including
the Parent) with respect to a possible business combination with the Company.
 
  In mid-December 1994, representatives of the Parent received a telephone
call from representatives of PaineWebber, acting on behalf of the Company,
inquiring whether the Parent would have an interest in some form of business
combination with the Company. Later that month, the Parent was provided with
certain non-confidential information on the Company. In January 1995,
representatives of the Parent and PaineWebber had several telephone
discussions concerning the Parent's interest in potentially acquiring the
Company. The Parent and the Company entered into the Confidentiality Agreement
effective February 1, 1995. See "Other Arrangements" above.
 
  On February 21, 1995, representatives of the Parent met in Denver with
representatives of the Company and PaineWebber and received a formal
presentation from senior management of the Company with respect to the
Company.
 
  On March 7, 1995, the Company publicly announced its decision to explore
alternatives to enhance long-term stockholder value, as well as the engagement
of PaineWebber as its exclusive financial advisor. Following this public
announcement, PaineWebber received nine unsolicited inquiries regarding the
Company. None of such inquiries resulted in due diligence reviews or
negotiations following the initial inquiry.
 
  Throughout the period from mid-February through May, the Company provided
detailed information to the Parent and the Parent conducted its assessment and
valuation of the Company. The Board of Directors of the Parent was apprised of
the potential acquisition at its regularly scheduled meeting on May 10, 1995.
A plant and mine tour of the Company's facilities was attended by
representatives of the Parent on May 23, 1995. Four other potential acquirors
of the Company, who had also executed confidentiality agreements to facilitate
further exploration of a possible acquisition of the Company, attended
separate presentations by senior management of the Company. Three of such
potential purchasers also attended separate plant and mine tours.
 
  In late May 1995, following these further due diligence investigations,
three of the remaining four parties (including the Parent) continued to pursue
the possible acquisition of the Company. Pursuant to the Board of Directors'
instructions, PaineWebber invited these three potential acquirors (including
the Parent) to submit, on or before June 12, 1995, written proposals with
respect to the possible acquisition of the Company.
 
  On May 31, 1995, the Parent submitted an acquisition proposal to the Company
conditioned upon, among other things, a commitment from WPG Affiliates to
support the transaction. By its terms, the proposal required acceptance by the
Company by the close of business on June 2, 1995 and would have prohibited
further negotiations with third parties for a period of time. On June 2, 1995,
the Executive Committee of the Board of Directors of the Company reviewed the
Parent's offer and concluded that the proposal did not justify termination of
the process of soliciting offers from the other interested parties and that
any discussions regarding a commitment from the WPG Affiliates should be held
directly with such WPG Affiliates. Following the June 2 meeting, PaineWebber
informed the Parent of the decision of the Executive Committee of the Board of
Directors and encouraged the Parent to submit a revised proposal.
 
                                      11
<PAGE>
 
  On June 12, 1995, the Company received a revised proposal from the Parent.
After reviewing this proposal and a proposal from one other party, the Company
concluded that they were both unacceptable, because of inadequacy of price
and/or omissions of certain material terms, among other reasons. Accordingly,
PaineWebber was instructed to continue to solicit proposals for the Company
and to review other alternatives available to the Company to increase
stockholder liquidity, including a secondary offering.
 
  On June 28, 1995, a representative of the Parent met with PaineWebber in New
York to evaluate whether there was any basis for continued discussions between
the parties.
 
  On July 5, 1995, a special meeting of the Executive Committee of the Board
of Directors of the Parent was held to review the proposed acquisition and
consider the various financial, strategic and legal matters as well as the
status of negotiations.
 
  Following that meeting, on July 6, 1995, the Parent submitted a further
proposal to the Company. Also in early July, the Company received a revised
proposal from the other interested party. On July 12, 1995, PaineWebber,
pursuant to instructions from the Company, advised the Parent that its
proposal was not the most attractive alternative available to the Company and
its stockholders, and the Parent was given an opportunity to present its best
and final proposal. On July 14, 1995 the Parent submitted a revised proposal
to acquire the Company pursuant to a one-step merger transaction at $10.55 per
Share in cash. Also on July 14, 1995, the other potential acquiror submitted a
revised proposal.
 
  On July 17, 1995, the Board of Directors held a meeting, at which
representatives of PaineWebber were present, to review and compare the terms
of the two pending proposals. At this meeting, the Board of Directors
determined that the Parent's proposal appeared to represent the best
alternative available to the Company and its stockholders, authorized
PaineWebber to conduct discussions with representatives of the Parent in order
to clarify certain terms of the Parent's proposal and, subject to obtaining
such clarification, authorized an exclusive period for discussion with the
Parent to permit the Parent to complete due diligence with respect to the
Company and to negotiate a definitive agreement for the sale of the Company.
 
  On July 20, 1995, the other party submitted a further revised proposal,
which the Company believed was substantially similar to such party's July 14,
1995 proposal. On July 24, 1995, the Company agreed to an exclusive period
with the Parent, expiring on August 9, 1995, previously authorized by the
Board of Directors of the Company.
 
  From July 24 through August 8, 1995, representatives of the Company and the
Parent held numerous meetings in which the terms of the Merger Agreement were
negotiated and due diligence was conducted. Separately, the Parent and
representatives of the WPG Affiliates negotiated the terms of the Irrevocable
Proxies pursuant to which the WPG Affiliates would support the transaction,
subject to the right of the WPG Affiliates to terminate such support if the
Company terminated the transaction with the Parent. As a result of further
discussion regarding the Parent's due diligence review and the price and
structure of the transaction, the Parent and the Company agreed to reduce the
consideration to be paid in the acquisition transaction from $10.55 to $10.50
per share. In addition, the Company and the Parent agreed to alter the
structure of the proposed acquisition from a one-step merger transaction to a
two-step transaction involving a tender offer followed by a merger. The
Company preferred the tender offer structure, which it believed would result
in a higher present value to holders of Shares because of the earlier receipt
of consideration for tendered Shares than would be expected in the one-step
merger transaction.
 
  On the evening of August 8, 1995, the Board of Directors of the Company met
to consider the final terms of the Merger Agreement. At this meeting,
PaineWebber delivered its opinion to the Board of Directors to the effect
that, as of such date, the $10.50 cash consideration proposed to be received
by the holders of the Shares pursuant to the Offer and the Merger was fair,
from a financial point of view, to such holders (other than stockholders that
are affiliates of Weiss, Peck & Greer, L.L.C.). At this meeting, the Board of
Directors of the Company unanimously approved and adopted the Merger Agreement
and resolved to recommend the Offer and the Merger to the Company's
stockholders. See "Reasons for the Recommendation."
 
  On August 9, 1995, the respective Boards of Directors of the Parent and the
Purchaser met, considered and each unanimously approved and adopted the Merger
Agreement. The Parent, the Purchaser and the Company
 
                                      12
<PAGE>
 
executed the Merger Agreement in the evening of August 9, 1995 and issued a
joint press release announcing the transactions at 7:00 A.M. EDT on August 10,
1995. At the time of the execution of the Merger Agreement, the Irrevocable
Proxies were executed in favor of the Purchaser by the parties thereto.
 
  REASONS FOR THE TRANSACTION; FACTORS CONSIDERED BY THE BOARD. In light of
the Board of Directors' review of the Company's competitive position, the
Company's financial history and current status, past and anticipated events in
the fertilizer industry and the prospects for the Company as an independent
entity, the Board of Directors determined that it would be in the best
interests of the stockholders to approve the Merger Agreement.
 
  In approving the Merger Agreement and the transactions contemplated thereby
and recommending that all holders of Shares tender them pursuant to the Offer,
the Board of Directors considered a number of factors including:
 
    (i) the opportunity to sell the Company at a time when the industry is
  experiencing its first period of strong fertilizer prices since 1989 at a
  price that reflects such strength, and the possibility that such strength
  will not be sustained;
 
    (ii) the recent trend toward consolidation among fertilizer producers;
 
    (iii) the risks to the Company and its stockholders of remaining
  independent in view of the Company's highly leveraged position, the
  volatile and cyclical nature of the fertilizer industry, the Company's
  dependence on a single type of fertilizer produced at a single facility,
  the Company's future capital needs, the Company's ability to compete in an
  increasingly global marketplace and the past and potential future effects
  on the Company of market downturns caused by weather, changes in government
  farm policies, political instability and other political considerations in
  foreign countries, supply and demand imbalances, currency fluctuations,
  changes in planted acreage, raw material costs and other uncontrollable and
  unpredictable forces;
 
    (iv) the presentation and opinion of PaineWebber at the August 8, 1995
  meeting of the Board of Directors to the effect that, as of such date, the
  $10.50 cash consideration proposed to be received by the holders of the
  Company's Shares pursuant to the Offer and in the Merger was fair, from a
  financial point of view, to such holders (other than stockholders that are
  affiliates of Weiss, Peck & Greer, L.L.C.). A copy of the written opinion
  of PaineWebber, which sets forth the procedures followed, matters
  considered, assumptions made and limitations of the review undertaken by
  PaineWebber, is attached hereto as Annex I. STOCKHOLDERS ARE URGED TO READ
  THE OPINION CAREFULLY IN ITS ENTIRETY;
 
    (v) the favorable price available to the Company's stockholders under the
  Merger Agreement compared to selling prices in other recent sale
  transactions in the fertilizer industry as measured by multiples of
  earnings and revenues;
 
    (vi) the historical market prices for the Voting Common Stock, including
  the fact that, although the proposed purchase price for the Voting Common
  Stock is less than recent Nasdaq National Market closing prices for the
  Voting Common Stock, such purchase price is in excess of the historical
  average trading prices of the Voting Common Stock over various periods
  preceding the announcement of the engagement of PaineWebber by the Company;
 
    (vii) the lack of liquidity in the market for the Voting Common Stock and
  the adverse consequences thereof for the Company and its stockholders;
 
    (viii) the stated intention of holders of 49.2% of the Shares (on a fully
  diluted basis) to tender into the Offer;
 
    (ix) the terms of the Merger Agreement, the Offer and the transactions
  contemplated thereby, including, among others, the right of the Company's
  Board of Directors to accept a proposal from another party and terminate
  the Offer and Merger Agreement, provided that the Parent would be entitled
  to a fee of $4.0 million in such event;
 
    (x) the availability of dissenters' rights of appraisal in the Merger;
 
    (xi) the financial strength of the Parent and the absence of any
  financing condition in the Offer; and
 
    (xii) the anticipated benefits of the Merger on the Company's employees
  and the community in which the Company operates.
 
                                      13
<PAGE>
 
  The Board of Directors did not assign relative weights to the above factors
or determine that any factor was of specific importance relative to any other
factor. Rather, the Board of Directors viewed its position and recommendations
as being based on the totality of the information presented to and considered
by it.
 
ITEM 5. PERSONS RETAINED, EMPLOYED OR TO BE COMPENSATED.
 
  PaineWebber has been retained by the Company to act as its exclusive
financial advisor with respect to the Offer, the Merger and matters arising in
connection therewith. Pursuant to a letter agreement dated January 11, 1995
between the Company and PaineWebber, the Company, as compensation for the
services of PaineWebber (i) paid PaineWebber $100,000 on April 3, 1995, (ii)
has agreed to pay PaineWebber a fee of $325,000 payable upon delivery of the

extent permitted by applicable securities laws, rules or regulations, all of
the Company's directors, executive officers, affiliates and subsidiaries who
own Shares presently intend to tender such Shares to the Purchaser pursuant to

ITEM 8. ADDITIONAL INFORMATION TO BE FURNISHED.
 
  Certain Litigation Relating to the Offer. Since the commencement of the
Offer, three class action complaints have been filed in the Delaware Chancery
Court on behalf of all persons who own Shares against the Company and certain
of its directors. In the suits, filed as Civil Action Nos. 11468, 11469 and
14477, respectively, the plaintiffs have alleged, among other things, that the
defendants have breached their fiduciary duties to holders of the Shares by,
among other things, entering into an agreement with the Purchaser and failing
to attempt to maximize shareholder value. Each suit seeks various remedies,
including an injunction to prevent consummation of the transaction, and
damages, costs and disbursements of the action.

Board of Directors
Nu-West Industries, Inc.
3010 Conda Road
Soda Springs, ID 83276
 
Gentlemen:
 
  Nu-West Industries, Inc. (the "Company") proposes to enter into an Agreement
and Plan of Merger (the "Agreement") with Agrium Inc. ("Agrium") and Agrium
Acquisition Corporation, a wholly owned indirect subsidiary of Agrium
("Acquisition"). Pursuant to the Agreement: (i) Acquisition will make a tender
offer (the "Offer") for all of the outstanding shares of voting and non-voting
common stock, par value $.01 per share ("Common Stock") of the Company at
$10.50 per share in cash (the "Consideration") and (ii) following completion
of the Offer, each issued and outstanding share of Common Stock (other than
shares owned by Agrium, Acquisition or any direct or indirect subsidiary of
Agrium and shares held by parties perfecting dissenters' rights) will be
converted in a merger (the "merger" and, together with the Offer, the
"Transaction") solely into the right to receive the Consideration.
 
  You have asked us whether or not, in our opinion, the Consideration to be
received in the Transaction by the holders of the Common Stock is fair, from a
financial point of view, to such holders (other than holders that are
affiliates of Weiss, Peck & Greer).
 
  In arriving at the opinion set forth below, we have among other things:
 
  (1) Reviewed, among other public information, the Company's Annual Reports,
      Forms 10-K and related financial information for the five fiscal years
      ended June 30, 1994 and the Company's Form 10-Q and the related
      unaudited financial information for the nine months ended March 31,
      1995;
 
  (2) Reviewed certain information, including financial forecasts, relating
      to the business, earnings, cash flow, assets and prospects of the
      Company furnished to us by the Company;
 
  (3) Conducted discussions with members of senior management of the Company
      concerning its businesses and prospects;
 
  (4) Reviewed the historical market prices and trading activity for the
      voting Common Stock and compared such price and trading history with
      that of certain other publicly traded companies which we deemed
      relevant;
 
  (5) Compared the financial position and operating results of the Company
      with those of certain other publicly traded companies which we deemed
      relevant;
 
  (6) Reviewed the proposed financial terms of the Transaction and compared
      such terms with the financial terms of certain other business
      combinations which we deemed relevant;
 
  (7) Reviewed a draft of the Agreement in the form presented to the Board of
      Directors of the Company;
 
  (8) Reviewed such other financial studies and analyses and performed such
      other investigations and took into account such other matters as we
      deemed appropriate, including our assessment of general economic,
      market and monetary considerations.
 
                                      I-1
<PAGE>
 
  In preparing our opinion, we have relied on the accuracy and completeness of
all information that was publicly available or supplied or otherwise
communicated to us by the Company and we have not independently verified such
information. We have assumed that the financial forecasts examined by us were
reasonably prepared on bases reflecting the best currently available estimates
and good faith judgments of the management of the Company as to the future
performance of the Company. We have not undertaken, and have not been provided
with, an independent evaluation or appraisal of the assets or liabilities
(contingent or otherwise) of the Company and have assumed that all material
liabilities (contingent or otherwise, known or unknown) of the Company are as
set forth in the Company's consolidated financial statements. In connection
with our engagement, we were requested to and did solicit third party
indications of interest in acquiring the Company. Our opinion is based upon
the regulatory, economic, monetary and market conditions existing on the date
hereof.
 
  Our opinion is directed to the Board of Directors of the Company and does
not constitute a recommendation to any holder of Common Stock as to whether or
not such holder should tender his or her shares pursuant to the Offer or
approve the Merger. This opinion does not address the relative merits of the
Transaction and any other potential transactions or business strategies
discussed by the Board of Directors of the Company.
 
  This opinion has been prepared solely for the use of the Board of Directors
of the Company and shall not be reproduced, summarized, described or referred
to or given to any other person or otherwise made public without the prior
written consent of PaineWebber Incorporated; provided, however, that this
letter may be reproduced in full in the Schedule 14D-9 relating to the Offer.
 
  PaineWebber Incorporated is currently acting as financial advisor to the
Company in connection with the Transaction and will receive a fee upon
delivery of this opinion and upon consummation of the Offer. We may provide
financial advisory or other investment banking services to Weiss, Peck & Greer
or its affiliates in the future.
 
  In the ordinary course of our business, we may actively trade the securities
of the Company and Agrium for our own account and for the accounts of our
customers and, accordingly, may at any time hold long or short positions in
such securities.
 
  On the basis of and subject to the foregoing, we are of the opinion that, as
of the date hereof, the Consideration to be received in the Transaction by the
holders of Common Stock is fair, from a financial point of view, to such
holders (other than shareholders that are affiliates of Weiss, Peck & Greer).
 
                                          Very truly yours,
 
                                          PAINEWEBBER INCORPORATED

                             INFORMATION STATEMENT
 
                                ---------------
 
                INFORMATION STATEMENT PURSUANT TO SECTION 14(F)
            OF THE SECURITIES EXCHANGE ACT OF 1934, AS AMENDED, AND
                             RULE 14F-1 THEREUNDER
 
                                ---------------
 
             NO VOTE OR OTHER ACTION OF THE COMPANY'S STOCKHOLDERS
          IS REQUIRED IN CONNECTION WITH THIS INFORMATION STATEMENT.
             NO PROXIES ARE BEING SOLICITED AND YOU ARE REQUESTED
                       NOT TO SEND THE COMPANY A PROXY.
 
  This Information Statement is being mailed on or about August 16, 1995 to
holders of shares of voting common stock, $.01 par value (the "Voting
Shares"), and non-voting common stock, $.01 par value (the "Non Voting
Shares," and collectively with the Voting Shares, the "Common Stock" or the
"Shares"), of Nu-West Industries, Inc., a Delaware corporation (the
"Company"). This Information Statement is being furnished in connection with
the possible designation by Agrium Acquisition Corporation (the "Purchaser"),
a Delaware corporation and a wholly owned subsidiary of Agrium U.S. Inc., a
Colorado corporation ("Agrium U.S."), a wholly owned subsidiary of Agrium
Inc., a Canadian corporation (the "Parent"), pursuant to an Agreement and Plan
of Merger dated as of August 9, 1995, by and among the Company, the Purchaser
and the Parent (the "Merger Agreement"), of certain persons (the "Purchaser
Designees") to be elected to the Board of Directors of the Company (the
"Board") by means other than through a meeting of the Company's stockholders.
 
  Pursuant to the Merger Agreement, the Purchaser has commenced a tender offer
(the "Offer") disclosed in the Tender Offer Statement on Schedule 14D-1 dated
August 16, 1995. The terms and conditions of the Offer are set forth in the
Offer to Purchase dated August 16, 1995 (the "Offer to Purchase") and related
Letter of Transmittal, which are being mailed by the Purchaser to the holders
of the Shares concurrently herewith. The Offer is subject to certain
conditions, which are summarized in the Offer to Purchase, including the
condition that there be a sufficient number of Shares properly tendered and
not withdrawn that, when added together with any Shares owned by Parent and
any of its subsidiaries and any Shares that the Parent and the Purchaser have
the right to acquire, will equal at least 60% of the Shares on a fully-diluted
basis. The Merger Agreement also provides, among other things, for the merger
(the "Merger") of the Purchaser into the Company, with the Company surviving
as a wholly owned subsidiary of Agrium U.S., as more fully described in the
Offer to Purchase and in the Company's Solicitation/Recommendation Statement
on Schedule 14D-9 (the "Schedule 14D-9") to which this Annex II is attached.
 
  Upon acquisition of Shares pursuant to the Offer that, when added together
with Shares owned by the Parent or any of its direct or indirect subsidiaries,
equal at least a majority of the then outstanding Voting Shares, the Parent
will be entitled to designate a number of individuals representing a majority
of the Board to be elected to the Board without action by the holders of the
Voting Shares. The Merger Agreement requires the Company to fill any vacancies
on the Board and increase the size of the Board to enable the Purchaser
Designees to be elected to the Board. The election of the Purchaser Designees
to the Board would result in a change in control of the Company.
 
  No action is required by the holders of the Shares in connection with the
election of the Purchaser Designees to the Company's Board of Directors.
However, Section 14(f) of the Securities Exchange Act of 1934, as amended,
requires the mailing to the holders of the Shares of the information set forth
in this Information Statement prior to a change in a majority of the Company's
directors otherwise than at a meeting of the Company's stockholders.
 
  IF THE PURCHASER DOES NOT ACQUIRE ANY SHARES PURSUANT TO THE OFFER, OR
TERMINATES THE OFFER, OR IF THE MERGER AGREEMENT IS TERMINATED PURSUANT TO ITS
TERMS BY THE PARENT, THE PURCHASER OR THE COMPANY PRIOR TO THE ELECTION OF THE
PURCHASER DESIGNEES, THE PURCHASER WILL NOT HAVE ANY RIGHT UNDER THE MERGER
AGREEMENT TO HAVE THE PURCHASER DESIGNEES ELECTED TO THE COMPANY'S BOARD OF
DIRECTORS.
 
  The information contained in this Information Statement concerning the
Parent, the Purchaser, Agrium U.S. and the Purchaser Designees has been
furnished to the Company by the Parent, the Purchaser and Agrium U.S. The
Company assumes no responsibility for the accuracy or completeness of such
information. The principal executive offices of the Parent, the Purchaser and
Agrium U.S. are located at Suite 426, 10333 Southport Road S.W., Calgary,
Alberta, Canada T2W 3X6.

EMPLOYMENT AGREEMENTS
 
  On December 1, 1994, the Company entered into an employment agreement (the
"Harlen Agreement") with Craig D. Harlen to serve as the Company's President
and Chief Executive Officer. The Harlen Agreement provides for an annual base
salary of $250,000 (which was increased to $257,500 effective July 1, 1995)
and is automatically extended for successive twelve month periods unless Mr.
Harlen or the Company gives 90 days written notice of its intention not to
renew the Harlen Agreement. Mr. Harlen's base salary for each successive
fiscal year is determined by the Compensation Committee of the Board, but
shall not be less than the base salary paid to Mr. Harlen in the previous
fiscal year. If the Company does not extend the Harlen Agreement or terminates
the Harlen Agreement without cause, the Company is obligated to pay, in
addition to accrued compensation, severance compensation equal to Mr. Harlen's
existing base salary in equal semi-monthly installments over the following
twelve months until paid in full. If the Harlen Agreement is terminated by
reason of a change in control (as defined below), the Company is obligated to
pay, in addition to accrued compensation, severance compensation of up to
three times the sum of (a) Mr. Harlen's existing base salary and (b) the
average of the incentive bonuses paid to Mr. Harlen for the two most recent
fiscal years of the Company preceding the
 
                                     II-7
<PAGE>
 
date of termination. The severance compensation payable upon a change in
control is payable in equal semi-monthly installments over the following
thirty-six months until paid in full, or, at Mr. Harlen's election, is payable
by a lump sum payment equal to the present value of the such cash payments. In
no event, however, shall such severance compensation exceed the amount that
the Company may deduct for federal income tax purposes by virtue of Section
280G of the Internal Revenue Code of 1986, as amended, or any successor
provision. In addition, the Harlen Agreement provides for certain payments in
the event of death or disability, and for the continuation of medical and
other benefits programs for a period of 18 months in the event of Mr. Harlen's
disability. The Harlen Agreement also contains non-competition and
confidentiality provisions.
 
  On December 1, 1994, the Company entered into employment agreements with
each of H. Alan Dalbach, Mark R. Sanders, Steven W. Gampp, Larry C. Dearing
and John D. Yokley. Each of these employment agreements contains annual base
salary, term, renewal, severance compensation in the event of non-renewal or
termination with or without cause, change of control, death and disability
benefit and non-competition and confidentiality provisions as described above
with respect to the Harlen Agreement. Effective July 1, 1995, these employment
agreements provide for annual base salaries in the aggregate amount of
$816,790 per year. The compensation paid to each of the employees under his
employment agreement for the three fiscal years ended June 30, 1995 is listed
in the Summary Compensation Table.
 
  For the purposes of the above employment agreements, a change in control
occurs (i) if any person other than the Company or WPG or its affiliates
acquires 40% or more of the outstanding Voting Shares of the Company, (ii) if
any merger, share exchange, issuance of capital stock, tender offer or similar
transaction results in the existing stockholders owning fewer than 50% of the
outstanding Voting Shares after the transaction, (iii) upon a sale, lease or
exchange of substantially all of the Company's assets other than a
sale/leaseback or similar financing transaction, or (iv) upon the adoption of
a plan for the liquidation or dissolution of the Company. A change of control
also occurs if, following any of the foregoing events, there is a substantial
change in the executive's duties, a reduction in his salary or benefits, a
relocation of the executive to an office other than his current office, an
uncured material breach by the Company of the agreement, a failure to obtain
the assumption of the agreement by any successor of the Company, or a failure
of the executive and the Company or its successor to negotiate a mutually
agreeable amendment to the current employment agreement or a new employment
agreement within 90 days after the change in control of the Company.
 
  The transactions contemplated by the Merger Agreement will result in a
change of control of the Company, as defined by the above agreements.
 
STOCK INCENTIVE PLANS
 
  In May 1988, the Company adopted an Employee Stock Option Plan (the "1988
Plan") to provide long-term incentives and rewards to the Company's officers
and employees. Under the 1988 Plan, options to acquire up to 300,000 shares of
Common Stock were authorized (as adjusted for the 1:6 reverse stock split in
December 1994). In 1994, the Company adopted the 1994 Employee Stock Incentive
Plan (the "1994 Plan") to provide long-term incentives and rewards to the
Company's officers and employees. Under the 1994 Plan, options to acquire up
to 300,000 shares of Common Stock were authorized (as adjusted for the 1:6
reverse stock split in December 1994). Both the 1988 Plan and the 1994 Plan
are administered by the Compensation Committee of the Board of Directors.
 
  Under the 1988 Plan and the 1994 Plan, the Company may grant both incentive
stock options intended to qualify under Section 422 of the Internal Revenue
Code of 1986, as amended ("ISOs"), and nonqualified stock options ("NSOs").
ISOs may be granted at exercise prices that are not less than the fair market
value of the Common Stock at the date of grant, except that the exercise price
of ISOs granted to any person who owns more than 10% of the outstanding Common
Stock must be at least 110% of the fair market value on the date of grant.
NSOs can be granted at exercise prices at or below the fair market value of
the Common Stock on the date of grant.
 
  The exercise price of an ISO or NSO may be paid with cash, shares of Common
Stock or recourse promissory notes at the option of the Compensation
Committee. The 1988 Plan and the 1994 Plan also provide
 
                                     II-8
<PAGE>
 
for the grant of SARs. An SAR permits the participant to surrender a specified
portion of his options in exchange for a payment representing the unrealized
appreciation of those options. No SARs have been granted under either of the
plans. Each of the plans also provides for supplemental bonuses granted at the
discretion of the Compensation Committee designed to offset all or part of the
tax liability incurred by participants who exercise ISOs or NSOs. The
supplemental bonus may not exceed the participant's tax liability arising from
the exercise.
 
  At June 30, 1995, (i) NSOs had been granted for an aggregate of 236,887
shares of Common Stock to 42 officers and employees, and NSOs had been
exercised to purchase 63,111 shares of Common Stock in prior fiscal years and
(ii) ISOs had been granted for an aggregate of 260,834 shares of Common Stock
to 49 officers and employees, all of which remained unexercised.
 
  As a result of the Offer, each holder of an outstanding option to purchase
Voting Shares under the 1988 Plan and the 1994 Plan shall be entitled to
exercise, subject to the consummation of the Offer, his or her options, in
order to tender such Shares in the Offer. In the event the Offer is not
completed, such options will remain outstanding but unexercised.
 
DIRECTOR COMPENSATION AND DIRECTOR STOCK OPTION PLAN
 
  Each non-employee director of the Company, other than directors associated
with WPG, receives an annual retainer of $35,000. Directors receive no
separate compensation for service on any committee of the Board of Directors.
All directors receive reimbursement for travel and other expenses directly
related to activities as directors.
 
  In November 1994, the Company adopted the Nonemployee Director Stock Option
Plan (the "Director Plan"), covering an aggregate of 50,000 shares of Common
Stock (adjusted for the reverse stock split in December 1994). Qualified non-
employee directors are eligible to receive grants of NSOs to purchase 4,167
shares of Common Stock on the date when service as a director commences, and
to receive NSOs for an additional 167 shares of Common Stock for each full
fiscal year of service as a director. All options to nonemployee Directors are
fully exercisable six months after the date of the grant. During the twelve
months ended June 30, 1995, Governor Andrus was granted an option to purchase
4,167 shares of Common Stock at an exercise price of $8.50. Such option
expires on January 3, 2005.
 
  As a result of the Offer, each holder of an outstanding option to purchase
Voting Shares under the Director Plan will be entitled to exercise, subject to
the consummation of the Offer, his or her options, in order to tender such
Shares in the Offer. In the event the Offer is not completed, such options
will remain outstanding but unexercised.
 
  Messrs. Land and Pfister are principals of WPG, which is a limited partner
of a company that provides management and financial consulting services to the
Company. See "--Compensation Committee Interlocks and Insider Participation."
 
  Pursuant to the Merger Agreement, Mr. Harlen and Governor Andrus have agreed
to resign as a Directors of the Company upon the Effective Date (as defined in
the Merger Agreement). The Company will pay Governor Andrus the unpaid balance
of his retainer for his remaining two year term as a Director on or prior to
the Effective Date. The Company will not grant any additional options to
purchase Common Stock to Governor Andrus. Mr. Harlen will not receive any
consideration for his resignation as a Director, but will be entitled to
severance compensation as provided for in the Harlen Agreement. See "Executive
Compensation--Employment Agreements."
 
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
  The Company has appointed Messrs. Lang and Pfister as members of the
Compensation Committee and the Audit Committee. Neither Messrs. Lang or
Pfister is or has been an officer or employee of the Company or any
subsidiary. The Company has no Compensation Committee interlocks.
 
  The Company and Weiss, Peck & Greer CDA, L.P. ("WPG-CDA") have entered into
an agreement under which WPG-CDA provides management and financial consulting
services to the Company for an annual fee of
 
                                     II-9
<PAGE>
 
$250,000, plus expenses. WPG is a limited partner of WPG-CDA, and Messrs. Lang
and Pfister are principals of WPG. The Company paid WPG-CDA $259,000 in fees
and related expenses during fiscal 1995 for such services.
 
DIRECTORS AND OFFICERS' INDEMNIFICATION
 
  Pursuant to the Merger Agreement, the Company must indemnify and hold
harmless, and after the Effective Date, the Parent and the Surviving
Corporation (as defined in the Schedule 14D-9) must indemnify and hold
harmless, each present employee, agent, director or officer of the Company and
the Company's subsidiaries (the "Indemnified Parties") (a) with respect to any
losses, claims, damages, liabilities, costs and expenses, including reasonable
attorneys' and expert witness fees, arising out of or pertaining to any action
or omission occurring prior to the Effective Date (including any which arise
out of or pertain to the transactions contemplated by the Merger Agreement)
and (b) as provided in their respective charters or by-laws in effect at the
date hereof (to the extent consistent with applicable law), which provisions
will survive the Merger and will continue in full force and effect for a
period of not less than five years from the Effective Date. In the event any
claim or claims (a "Claim or Claims") are asserted or made pursuant to the
preceding sentence within such five-year period, all rights to indemnification
in respect of any such Claim or Claims shall continue until disposition of any
and all such Claims. In the event that a claim is asserted against any
Indemnified Party with respect to any matter to which the indemnities
contained in this section relate, the Indemnified Party shall give prompt
written notice to the Surviving Corporation setting forth in reasonable detail
the basis for such claim for indemnification. The Surviving Corporation has
the right, at its election, to take over the defense or settlement of such
claim at its own expense by giving prompt notice to that effect to the
Indemnified Party. If the Surviving Corporation has assumed the defense of any
Claim, the Surviving Corporation is authorized to consent to a settlement of,
or the entry of any judgment arising from, any such Claim, without the prior
written consent of the Indemnified Party; provided, however, that a condition
to any such settlement will be a complete release of the Indemnified Party
with respect to such Claim. If the Surviving Corporation does not, within
thirty days after receipt of the Indemnified Party's notice of Claim, (x) give
such notice to take over the defense of such Claim and proceed to defend the
Claim or (y) object to such Claim in writing to the Indemnified Party, then
the Indemnified Party will have the right to undertake the defense of such
Claim and the Surviving Corporation will pay to the Indemnified Party the
reasonable fees and expenses of its counsel. The Surviving Corporation will
not be liable for any settlement effected without its consent, which consent
will not be unreasonably withheld. The Indemnified Party will at all times
have the right, at its option and expense, to participate fully in, but not to
control, any such defense. Without limiting the foregoing, the Company and,
after the Effective Date, the Surviving Corporation, to the extent permitted
by applicable law, will periodically advance reasonable expenses as incurred
with respect to the foregoing to the fullest extent permitted under applicable
law provided the person to whom the expenses are advanced provides an
undertaking to repay such advances if it is ultimately determined that such
person is not entitled to indemnification. In the event that within five years
from the Effective Date the Surviving Corporation consolidates or merges with
or into any other person or transfers all or substantially all of its assets
to any person and such person surviving such consolidation or merger or to
which such assets have been transferred is not a Delaware corporation, the
Surviving Corporation will enter into an agreement pursuant to which such
person must agree to provide indemnification substantially equivalent to that
required of the Company hereunder.

<PAGE>
 
or be inconsistent with the Merger or the Merger Agreement (including, without
limitation, any Acquisition Proposal (as defined in the Merger Agreement)), at

the Irrevocable Proxies is given to the transferee and the transferee agrees
that the shares transferred will remain subject to the Irrevocable Proxies
and, in connection therewith, executes and delivers to the Parent a proxy
covering such shares in form and substance satisfactory to the Parent, which
proxy shall be in substantially the form of the Irrevocable Proxies; or (ii)
the transfer is to the Parent or its designee pursuant to the Offer. The

  Agreement and Plan of Merger dated as of August 9, 1995 (this "Agreement")
by and among Agrium Inc., a Canadian corporation ("Purchaser"), Agrium
Acquisition Corporation, a Delaware corporation and wholly-owned subsidiary of
Purchaser ("Acquisition"), and Nu-West Industries, Inc., a Delaware
corporation (the "Company"). (Acquisition and the Company are hereinafter
collectively referred to as the "Constituent Corporations.")
 
  Whereas, Purchaser and the Boards of Directors of the Constituent
Corporations (a) desire to enter into this Agreement and (b) have approved the
merger of Acquisition with and into the Company (the "Merger"), all upon the
terms and subject to the conditions set forth herein.
 
  Now, Therefore, the parties hereto agree as follows:
 
                                   ARTICLE I
 
                                 Tender Offer
 
  Section 1.1 The Tender Offer.
 
  (a) As long as none of the events set forth in Exhibit A hereto shall have
occurred or be existing, Acquisition shall, and Purchaser shall cause
Acquisition to, commence as promptly as practicable, but in no event later
than five business days after the date hereof, a tender offer (as amended or
extended from time to time, the "Tender Offer") subject to the conditions set
forth in Exhibit A hereto, for all outstanding shares of Voting Common Stock,
par value $.01, and Nonvoting Common Stock, par value $.01 (collectively, the
"Shares") of the Company, which Tender Offer is conditioned upon a sufficient
number of Shares being properly tendered and not withdrawn, which, when added
together with any Shares owned by Purchaser and any of its subsidiaries or
which Purchaser and Acquisition have the right to acquire, will equal at least
60% of the Shares on a fully diluted basis. The per Share price to be paid in
the Tender Offer, which shall be paid net to the sellers in cash, shall be
$10.50. Purchaser agrees, subject to the terms and conditions of the Tender
Offer, to pay for all Shares tendered that it is obligated to purchase as soon
as legally permissible.
 
  (b) Without the prior written consent of the Company, Acquisition shall not
decrease the Merger Price (as defined in Section 4.1), decrease the number of
Shares being sought in the Tender Offer, change the form of consideration
payable in the Tender Offer, add additional conditions to the Tender Offer or
make any other material change in the terms or conditions to the Tender Offer.
 
  (c) On the date the Tender Offer is commenced, Purchaser and Acquisition
shall file with the Securities and Exchange Commission (the "SEC") a tender
offer statement on Schedule 14D-1 (together with all amendments and
supplements thereto, the "Schedule 14D-1") with respect to the Tender Offer.

by reference the Offer to Purchase (or portions thereof) and forms of the
related Letter of Transmittal and summary advertisement and shall comply as to
form in all material respects with the requirements of the Securities Exchange
Act of 1934, as amended (the "Exchange Act"), and the rules and regulations
promulgated thereunder (the "Rules and Regulations"). If at any time prior to
the expiration or termination of the Tender Offer any event occurs which is
required by the Act and the Rules and Regulations to be described in an
amendment to the Schedule 14D-1 or any supplement thereto, Purchaser and
Acquisition will file and disseminate, as required, an amendment or supplement
which complies in all material respects with the Act and the Rules and
Regulations. The Company and its counsel shall be given an opportunity to
review the Schedule 14D-1 and any amendment or supplement thereto prior to its
being filed with the SEC. Purchaser and Acquisition agree to provide the
Company and its counsel with any written comments (and to inform the Company

Company or the holders of any securities of the Company:
 
    (a) All Shares which are held by the Company as treasury shares, all
  authorized and unissued Shares and any Shares owned by Purchaser,
  Acquisition or any other direct or indirect subsidiary of Purchaser, shall
  be canceled.
 
    (b) Each other outstanding Share (other than Shares held by Dissenting
  Stockholders (as defined in Section 4.3)) shall be converted into the right
  to receive (U.S.)$10.50 net in cash or such higher amount per Share as may
  be paid to any holder of Shares pursuant to the Tender Offer (the "Merger
  Price").
 
    (c) Each issued and outstanding share of capital stock of Acquisition

  share of Voting Common Stock, par value $.01 per share, of the Surviving
  Corporation.
 
    (d) Except as provided in Section 7.6 and as set forth in Schedule 4.1,

receive pursuant to Section 4.1(b), upon surrender to the Paying Agent of the
certificate or certificates, which immediately prior to the Effective Date
represented such outstanding Shares, for cancellation, the aggregate amount of
cash into which those Shares shall have been converted in the Merger. Until so

represented outstanding Shares, shall represent solely the right to receive,
upon

<PAGE>
 
surrender, the aggregate amount of cash into which the Shares represented

require appraisal of their shares (a "Dissenting Stockholder"), shall not be
converted as described in Section 4.1 but shall become, at the Effective Date,
by virtue of the Merger and without any further action, the right to receive
such consideration as may be determined to be due to such Dissenting
Stockholder pursuant to the GCL; provided, however, that Shares outstanding
immediately prior to the Effective Date and held by a Dissenting Stockholder
who shall, after the Effective Date, withdraw his demand for appraisal or lose
his right of appraisal, in either case pursuant to the GCL, shall be deemed to
be converted as of the Effective Date, into the right to receive the Merger
Price. The Company shall give Purchaser (a) prompt notice of any written
demands for appraisal of shares of capital stock of the Company received by
the Company and (b) the opportunity to direct all negotiations and proceedings
with respect to any such demands. The Company shall not, without the prior
written consent of Purchaser, voluntarily make any payment with respect to, or
settle, offer to settle or otherwise negotiate, any such demands.
 
  Section 4.4 Closing of the Company's Transfer Books. Upon the Effective
Date, the stock transfer books of the Company shall be closed and no transfer
of Shares (other than shares of Voting Common Stock, par value $.01 per share,
into which the capital stock of Acquisition is to be converted pursuant to the
Merger) shall thereafter be made.
 
  Section 4.5 Status of Share Certificates. From and after the Effective Date,
the holders of certificates evidencing ownership of Shares outstanding
immediately prior to the Effective Date shall cease to have any rights with
respect to such Shares except as otherwise provided for herein or by
applicable law.

and Acquisition from performing, in any material respect, their respective
obligations under this Agreement (a "Purchaser Material Adverse Effect").
 
  (b) The execution and delivery of this Agreement by Purchaser and
Acquisition does not, and consummation of the transactions contemplated hereby

of appropriate merger documents as required by the GCL, and (ii) where the
failure to obtain such consents, licenses, permits, approvals, waivers,
authorizations or orders, or to make such filings or notifications, would not,
either individually or in the aggregate, constitute a Purchaser Material
Adverse Effect.
 
  Section 5.4 Information. (a) The documents pursuant to which the Tender
Offer is made, including a Schedule 14D-1, an Offer to Purchase and a related
Letter of Transmittal and any amendments thereof or supplements thereto (the
"Offer Documents"), will not at the respective times such documents are filed
with the SEC, contain any untrue statement of a material fact or omit to state
any material fact (other than information with respect to the Company supplied
by the Company, with respect to which no representation is made) required to
be stated therein or necessary in order to make the statements therein, in
light of the circumstances under which they were made, not misleading. None of
the information to be supplied by Purchaser or Acquisition for inclusion in a
proxy statement in connection with the meeting of the Company's stockholders,
if required, described in Section 7.2 hereof (the "Proxy Statement") or in an
information statement mailed to the Company's stockholders (the "Information
Statement") or any amendments thereof or supplements thereto, will, at the

which they were made, not misleading.
 
  (b) Since their inception, Purchaser and its subsidiaries have filed all
forms, reports, statements and other documents required to be filed with
applicable Canadian and United States securities authorities, except where the
failure to file such documents would not have a Purchaser Material Adverse
Effect (all such forms, reports, statements and other documents being referred

including all Purchaser Reports filed after the date of this Agreement and
prior to the Effective Date, (i) were or will be prepared in all material

contain any untrue statement of a material fact or omit to state a material
fact required to be stated therein or necessary in order to make the
statements therein, in light of the circumstances under which they were made,
not misleading, except where any such statement or omission would not have a
Purchaser Material Adverse Effect. Notwithstanding this Section 5.4(b),
Purchaser shall not be deemed to represent or warrant the preparation or
accuracy of any Purchaser Report, statement, document or other information
included in the Purchaser Reports that were provided to the Purchaser for

                                  ARTICLE VI
 
                 Representations and Warranties of the Company
 
  The Company represents and warrants to Purchaser and Acquisition as follows:
 
  Section 6.1 Organization and Qualification; Subsidiaries. Each of the
Company and its subsidiaries (as defined in Section 10.7) is duly organized,
validly existing and in good standing under the laws of the jurisdiction of
its incorporation or organization, has all requisite corporate or partnership
power and authority to own, lease and operate its properties and to carry on
its business as it is now being conducted and is duly qualified and in good
standing to do business in each jurisdiction in which the nature of the
business conducted by it or the ownership or leasing of its properties makes
such qualification necessary, other than where the failure to be so duly
qualified and in good standing would not have a Company Material Adverse
Effect. The term "Company Material Adverse Effect" as used in this Agreement
shall mean any change or effect that, individually or when taken together with
all other such changes or effects, would be materially adverse to the
financial condition, results of operations or fair market value of the Company
and its subsidiaries, taken as a whole. Schedule 6.1 of the disclosure
schedule delivered to Purchaser by the Company on the date hereof (the
"Company Disclosure Schedule") sets forth, as of the date of this Agreement, a
true and complete list of all the Company's subsidiaries and investments in
business entities together with (A) the jurisdiction of incorporation or
organization of each subsidiary and the percentage of each subsidiary's
outstanding capital stock or other equity interests owned by the Company or
another subsidiary of the Company, and (B) an indication of whether each such
subsidiary is a "Significant Subsidiary" as defined in Rule 1-02 of Regulation
S-X of the SEC. Neither the Company nor any of its subsidiaries owns or has
owned since its inception (other than Nu-South Industries, Inc., a Delaware
corporation, the Conda Partnership, an Idaho general partnership and Nu-Gulf
Industries, Inc., a Delaware corporation), an equity interest in any other
corporation, partnership or joint venture arrangement or other business entity
that is or was material to the financial condition, results of operations or
fair market value of the Company and its subsidiaries, taken as a whole.
 
  Section 6.2 Charter and By-Laws. The Company has heretofore furnished to
Purchaser complete and correct copies of the charter and the By-Laws or the
equivalent organizational documents, in each case as amended or restated, of
the Company and each of its subsidiaries. Neither the Company nor any of its
subsidiaries is in violation of any of the provisions of its charter or any
material provision of its By-Laws (or equivalent organizational documents).

authorized shares of capital stock of any of such corporate entities subject
to) any preemptive or similar rights created by statute, the charter or By-
Laws (or the equivalent organizational documents) of the Company or any of its
subsidiaries, or any agreement to which the Company or any of its subsidiaries
is a party or bound, and such outstanding shares or other equity interests
owned by the Company or a subsidiary of the Company are owned free and clear
of all security interests, liens, claims, pledges, agreements, limitations on
the Company's or such subsidiaries' voting rights, charges or other
encumbrances of any nature whatsoever, except as set forth in the Second

the Company Disclosure Schedule, there are no obligations, contingent or
otherwise, of the Company or any of its subsidiaries (i) to repurchase, redeem
or otherwise acquire any shares of the capital stock of the Company, or the
capital stock or other equity interests of any subsidiary of the Company or
(ii) (other than advances to subsidiaries in the ordinary course of business)
to provide material funds to, or make any material investment in (in the form
of a loan, capital contribution or otherwise), or provide any guarantee with
respect to the obligations of, any subsidiary of the Company or any other
person. Except as described in Schedule 6.3(b) to the Company Disclosure
Schedule, neither the Company nor any of its subsidiaries (x) directly or
indirectly owns, (y) has agreed to purchase or otherwise acquire or (z) holds
any interest convertible into or exchangeable or exercisable for, 5% or more
of the capital stock of any corporation, partnership, joint venture or other
business association or entity (other than the subsidiaries of the Company set
forth in Schedule 6.1 of the Company Disclosure Schedule). Except as set forth
in Schedule 6.3(b) of the Company Disclosure Schedule and except for any
agreements, arrangements or commitments between the Company and its
subsidiaries or between such subsidiaries, there are no agreements,
arrangements or commitments of any character (contingent or otherwise)
pursuant to which any person is or may be entitled to receive any payment
based on the revenues or earnings, or calculated in accordance therewith, of
the Company or any of its subsidiaries. There are no voting trusts, proxies or
other agreements or understandings to which the Company or any of its
subsidiaries is a party or by which the Company or any of its subsidiaries is
bound with respect to the voting of any shares of capital stock of the Company
or any of its subsidiaries.

Company to obtain any consent, license, permit, approval, waiver,
authorization or order of, or to make any filing with or notification to any
Governmental Entities, except (i) for applicable requirements, if any, of the
Securities Act, the Exchange Act, state securities or Blue Sky Laws, and the

Adverse Effect.

of the Company, threatened regarding suspension or cancellation of any of the

stock appreciation right, profit sharing, incentive compensation, deferred
compensation, savings, thrift, vacation pay, severance pay, or other employee
compensation or Plan, agreement, practice, or arrangement, whether written or
unwritten, whether or not legally binding (collectively, the "Plans"). For

Plan that describes the terms of the Scheduled Plan.

and regulations, including without limitation ERISA. Each Scheduled Plan that
is intended to be a qualified plan has received a favorable determination
letter from the Internal Revenue Service; nothing has occurred since the date
of the most recent favorable determination letter that would cause the loss of
the Scheduled Plan's qualification; and each such Scheduled Plan has at all

with the applicable requirement of the Code and the applicable Treasury
Regulations.
 
  (d) Neither the Company nor any party in interest (as such term is defined

paid in full or accrued, subject only to normal retrospective adjustments in
the ordinary course for policy years or other applicable policy periods ending
on or before the Effective Date.
 
  (g) Neither the Company nor any member of the Controlled Group has any

the Code or the federal consolidated return regulations (or any predecessor
provision of any Code section or the regulations), and, to the knowledge of
the Company, no event has occurred since June 30, 1994 that would prevent the

attorney client privilege, the Company shall provide Purchaser with a list of
such materials and a summary of their contents, and the Company shall
cooperate with Purchaser to provide Purchaser with access to such materials if
such access can be provided without violation of the attorney client
privilege); and (ix) neither the Company nor its subsidiaries are subject to
or have entered into any agreement requiring that they pay to, defend,

14D-9, the Proxy Statement, the Information Statement, the solicitation of
stockholder approvals and all other matters related to the consummation of the
transactions contemplated hereby; provided, however, that "Expenses" shall not

  Section 7.6 Employee Stock Options; Warrant. On or before the Effective Date
of the Merger, the Company shall take all steps necessary for all outstanding
options granted under the Stock Option Plans and the Nonemployee Plan to be
converted by the Merger into the right to receive for each Share covered
thereby a cash amount equal to the excess of the Merger Price over the option
exercise price. Such amount shall be paid by Purchaser on the Effective Date.
On the Effective Date of the Merger, all rights under the Warrants shall be
converted by the Merger into the right to receive for each Share covered
thereby the right to receive the Merger Price upon payment to the Company of
the applicable Warrant exercise price. The Company shall take no action, or
allow any action to be taken, or fail to take any action, that would cause or
result in any acceleration of exercisability of outstanding options granted
under the Stock Option Plans and the Nonemployee Plan.
 
  Section 7.7 Indemnification and Insurance. The Company shall indemnify and
hold harmless, and after the Effective Date, Purchaser and the Surviving
Corporation shall indemnify and hold harmless, each present employee, agent,
director or officer of the Company and the Company's subsidiaries (the
"Indemnified Parties") (a) with respect to any losses, claims, damages,
liabilities, costs and expenses, including reasonable attorneys' and expert
witness fees, arising out of or pertaining to any action or omission occurring
prior to the Effective Date (including any which arise out of or pertain to
the transactions contemplated by this Agreement) and (b) as provided in their
respective charters or by-laws in effect at the date hereof (to the extent
consistent with applicable law), which provisions shall survive the Merger and
shall continue in full force and effect for a period of not less than five
years from the Effective Date. In the event any claim or claims (a "Claim or
Claims") are asserted or made pursuant to the preceding sentence within such
five-year period, all rights to indemnification in respect of any such Claim
or Claims shall continue until disposition of any and all such Claims. In the
event that a claim is asserted against any Indemnified Party with respect to
any matter to which the indemnities contained in this section relate, the
Indemnified Party shall give prompt written notice to the Surviving
Corporation setting forth in reasonable detail the basis for such claim for
indemnification. The Surviving Corporation shall have the right, at its
election, to take over the defense or settlement of such claim at its own
expense by giving prompt notice to that effect to the Indemnified Party. If
the Surviving Corporation shall have so assumed the defense of any Claim, the
Surviving Corporation shall be authorized to consent to a settlement of, or
the entry of any judgment arising from, any such Claim, without the prior
written consent of the Indemnified Party; provided,
 
                                      18
<PAGE>
 
however, that a condition to any such settlement shall be a complete release
of the Indemnified Party with respect to such Claim. If the Surviving
Corporation does not, within thirty days after receipt of the Indemnified
Party's notice of Claim, (x) give such notice to take over the defense of such
Claim and proceed to defend the Claim or (y) object to such Claim in writing
to the Indemnified Party, then the Indemnified Party shall have the right to
undertake the defense of such Claim and the Surviving Corporation shall pay to
the Indemnified Party the reasonable fees and expenses of its counsel. The
Surviving Corporation shall not be liable for any settlement effected without
its consent, which consent shall not be unreasonably withheld. The Indemnified
Party shall at all times have the right, at its option and expense, to
participate fully in, but not to control, any such defense. Without limiting
the foregoing, the Company and, after the Effective Date, the Surviving
Corporation, to the extent permitted by applicable law, will periodically
advance reasonable expenses as incurred with respect to the foregoing to the
fullest extent permitted under applicable law provided the person to whom the
expenses are advanced provides an undertaking to repay such advances if it is
ultimately determined that such person is not entitled to indemnification. In
the event that within five years from the Effective Date the Surviving
Corporation shall consolidate or merge with or into any other person or shall
transfer all or substantially all of its assets to any person and such person
surviving such consolidation or merger or to which such assets shall have been
transferred is not a Delaware corporation, the Surviving Corporation shall
enter into an agreement pursuant to which such person shall agree to provide
indemnification substantially equivalent to that required of the Company
hereunder.
 
  Section 7.8 Employee Benefits. For a period of two years from the Effective
Date, Purchaser and the Surviving Corporation agree to honor in accordance
with their terms the Company's employee benefit plans, in each case to the
extent the same have been delivered or made available to Purchaser for review,
provided however that Purchaser or the Surviving Corporation may amend or
terminate any such plan at any time after the Effective Date to the extent the
amendment or termination is deemed to be necessary or appropriate to comply
with the requirements of applicable law.
 
  Section 7.9 Maintenance of Financing. Purchaser and Acquisition shall at all
times have available to them funds sufficient to consummate the Tender Offer
and the Merger on the terms contemplated by this Agreement.
 
  Section 7.10 Resignation of Directors. The Company will obtain the
resignations of all of the Continuing Directors of the Company on the
Effective Date.
 
  Section 7.11 Board of Directors. Upon the acquisition of Shares pursuant to
the Tender Offer, which, when added together with Shares owned by Purchaser or
any of its direct or indirect subsidiaries, equal at least a majority of the
then outstanding shares of Voting Common Stock, the Company shall fill any
vacancies and increase the size of its Board of Directors as necessary to
enable Purchaser to designate at its option a majority of the Company's Board
of Directors, and shall cause Purchaser's designees to be so elected and shall
mail promptly the information required by Section 14(f) of the Act and Rule
14f-1 promulgated thereunder.

approximately 9.4 million common shares on a fully diluted basis and upon the
expiration of the waiting period under the Hart-Scott-Rodino Anti-Trust
Improvements Act. Agrium expects to take up and pay for the common shares
under the offer by mid-September. The merger agreement provides that any
untendered shares will be converted into the right to receive US$10.50 per
share in cash as soon as practical after the completion of the tender.
 
The Board of Directors of Nu-West has unanimously approved the merger
agreement and the transaction. Paine Webber Incorporated has acted as
financial advisor to Nu-West and has rendered a fairness opinion in connection
with the transaction. The Board of Directors of Agrium has also unanimously
approved the merger agreement and the transaction.
 
Agrium also announced that Nu-West shareholders owning approximately 4.6
million common shares have agreed to tender into the offer.

Mr. Van Brunt, commenting on the prospective merger, said "This merger creates
a strong strategic business combination for the production and sale of the
three primary plant nutrients; phosphate, nitrogen and potash. In addition,
Nu-West's products are sold into Agrium's primary western United States and
Canadian wholesale markets and strengthens the phosphate supply position to
our large U.S. retail subsidiaries and our Elephant Brand dealer network in
Canada."
 
Mr. Harlen stated, "This transaction is the next logical step in securing a
positive future for Nu-West and its various constituents. Over the last few
years we have established ourselves as a significant phosphate producer and
now seek to expand our horizons through a strategic relationship that will
strengthen and enhance our marketing and production. This merger will better
position both companies for the global marketplace that is upon us."
 
Agrium, based in Calgary, Alberta, is one of North America's largest
integrated and diversified fertilizer companies.
 
Nu-West is engaged in the manufacture and sale of phosphate fertilizer
products.

August 16, 1995
 
TO OUR STOCKHOLDERS:
 
  We are pleased to inform you that Nu-West Industries, Inc. has entered into
a merger agreement with Agrium Inc., pursuant to which Agrium has agreed to
acquire Nu-West. Agrium is one of North America's largest integrated and
diversified fertilizer companies.
 
  Under the terms of the merger agreement, a wholly-owned subsidiary of Agrium
has today commenced a tender offer for all of the outstanding shares of common
stock of Nu-West at $10.50 per share in cash. The tender offer will be
followed by a merger pursuant to which any remaining holders of Nu-West common
stock will receive $10.50 per share in cash and Nu-West will become a wholly-
owned subsidiary of Agrium.
 
  YOUR BOARD OF DIRECTORS HAS UNANIMOUSLY APPROVED THE MERGER AGREEMENT,
DETERMINED THAT THE TENDER OFFER AND THE MERGER, CONSIDERED AS A WHOLE, ARE
FAIR TO AND IN THE BEST INTERESTS OF THE STOCKHOLDERS OF NU-WEST, AND
RECOMMENDS THAT ALL OF THE HOLDERS OF COMMON STOCK OF NU-WEST ACCEPT THE
TENDER OFFER AND TENDER ALL OF THEIR SHARES AND APPROVE THE MERGER AGREEMENT
AND THE MERGER, IF REQUIRED BY LAW.
 
  In arriving at its decision, the Board of Directors considered a number of
factors, including the opinion of PaineWebber Incorporated, Nu-West's
financial advisor, that the consideration to be received in the tender offer
and the merger by the holders of common stock is fair, from a financial point
of view, to such shareholders (other than shareholders that are affiliates of
Weiss, Peck & Greer, L.L.C.).
 
  Accompanying this letter is a copy of Nu-West's Solicitation/Recommendation
Statement on Schedule 14D-9, which contains information regarding the factors
considered by the Board of Directors and its deliberations, a copy of the
opinion of PaineWebber Incorporated and certain other information regarding
the tender offer and the merger, and a copy of an Information Statement
pursuant to Rule 14f-1 under the Exchange Act of 1934, as amended. In
addition, enclosed is the Offer to Purchase dated August 16, 1995, of the
subsidiary of Agrium, together with related materials, including a Letter of
Transmittal to be used for tendering your shares. WE URGE YOU TO READ THE
ENCLOSED MATERIALS CAREFULLY BEFORE MAKING A DECISION WITH RESPECT TO
TENDERING YOUR SHARES IN THE TENDER OFFER.
 
  I personally, along with the Board of Directors, management and employees of
Nu-West, wish to thank you for your loyal support through the years. The Board
of Directors recommends that you accept the tender offer and tender all of
your shares.
 
                                          On behalf of the Board of Directors
