                          INDEPENDENT AUDITORS' REPORT
 
The Board of Directors
Arcadian Corporation:
 
     We have reviewed the condensed consolidated balance sheet of Arcadian
Corporation and subsidiaries as of September 30, 1996, and the related condensed
consolidated statements of operations and cash flows for the three and
nine-month periods ended September 30, 1996 and 1995, in accordance with
standards established by the American Institute of Certified Public Accountants.
 
     A review of interim financial information consists principally of obtaining
an understanding of the system for the preparation of interim financial
information, applying analytical review procedures to financial data, and making
inquiries of persons responsible for financial and accounting matters. It is
substantially less in scope than an audit in accordance with generally accepted
auditing standards, the objective of which is the expression of an opinion
regarding the financial statements taken as a whole. Accordingly, we do not
express such an opinion.
 
     Based on our review, we are not aware of any material modifications that
should be made to the condensed consolidated financial statements referred to
above for them to be in conformity with generally accepted accounting
principles.
 
     We have previously audited, in accordance with generally accepted auditing
standards, the consolidated balance sheet of Arcadian Corporation and
subsidiaries as of December 31, 1995, and the related consolidated statements of
operations, stockholders' equity and cash flows for the year then ended (not
presented herein); and in our report dated February 9, 1996, we expressed an
unqualified opinion on those consolidated financial statements. In our opinion,
the information set forth in the accompanying condensed consolidated balance
sheet as of December 31, 1995, is fairly presented, in all material respects, in
relation to the consolidated balance sheet from which it has been derived.

                     ARCADIAN CORPORATION AND SUBSIDIARIES
 
              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                  (UNAUDITED)
 
1. BASIS OF PRESENTATION
 
     The accompanying condensed consolidated financial statements of Arcadian
Corporation and its subsidiaries (collectively "Company") are unaudited and have
been prepared in accordance with generally accepted accounting principles for
interim financial information and with the instructions to the Quarterly Report
on Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include
all of the information and footnotes required by generally accepted accounting
principles for complete financial statements. These condensed consolidated
financial statements should be read in conjunction with the consolidated
financial statements and the notes thereto included in the Company's Annual
Report on Form 10-K for the fiscal year ended December 31, 1995.
 
     In the opinion of the Company, the accompanying condensed consolidated
financial statements contain all adjustments (consisting of only normal,
recurring adjustments) necessary to present fairly the financial position,
results of operations, and cash flows of the Company as of the dates and for the
periods presented.
 
     Because of the seasonal nature of the Company's business, the results of
operations for the periods presented are not necessarily indicative of the
results of operations for a full fiscal year.
 
     The accompanying condensed consolidated financial statements of the Company
include the results of operations of Arcadian Corporation ("Corporation") and
its subsidiaries, including Arcadian Partners, L.P. ("Partners"), Arcadian
Fertilizer, L.P. ("Fertilizer"), and their respective subsidiaries (collectively
"Partnership"), on a consolidated basis. All intercompany balances and
transactions have been eliminated in consolidation. Prior to the August 1995
Merger, the approximately 55% limited partner interest in the Partnership
represented by the preference units was accounted for as a "Non-Controlling
Interest."
 
2. PRO FORMA
 
     The following unaudited pro forma financial information of the Company for
the nine months and three months ended September 30, 1995, gives effect to the
August 1995 Merger and Public Offering as if they had occurred on January 1,
1995. The pro forma data presented below do not purport to represent what the
Company's results of operations would have been had such transactions in fact
occurred as of January 1, 1995, or to project the Company's results of
operations in any future periods:

* The pro forma adjustments include amortization of goodwill resulting from the
  August 1995 Merger, the decrease in interest expense as a result of the
  Company's redemption of its 16% Junior Subordinated Exchange Debentures due
  December 15, 2004, the elimination of the non-controlling interest in the
  Partnership represented by the preference units, and the income tax effect of
  the pro forma adjustments.

4. NET INCOME PER COMMON SHARE
 
     For purposes of computing net income per common share, the conversion of
Mandatorily Convertible Preferred Stock, Series A ("Preferred Stock"), which is
a common stock equivalent because of its mandatory conversion feature, is
assumed when such conversion is dilutive. Common and common equivalent shares
outstanding were 46,501,379 and 22,522,466 for the nine months ended September
30, 1996 and 1995, and 45,679,722 and 33,837,816 for the three months ended
September 30, 1996 and 1995, respectively. Net income per common share disclosed
herein is computed on a primary basis only, as net income per common share
computed on a fully diluted basis differs from the amounts disclosed by less
than 3%.

     At September 30, 1996, there was no outstanding balance on the Company's
$100 million revolving credit facility, and the amount available for borrowing
in the form of loans and letters of credit, after considering outstanding and
committed letters of credit of $40 million, was $60 million.
 
7. RESTRICTED RESERVE ACCOUNTS
 
     At September 30, 1996, restricted reserve accounts of $58 million were
comprised of a $28 million Cash Collateral Account maintained by Fertilizer for
the benefit of the holders of the First Mortgage Notes, a $20 million Debt
Service Reserve Account maintained by Partners for the benefit of the holders of
the 10 3/4% Series B Senior Notes due 2005 ("Senior Notes"), and a $10 million
Cash Reserve Account maintained by Fertilizer for the benefit of the Second
Lessor (as defined in Note 9).
 
8. STOCKHOLDERS' EQUITY
 
SECONDARY OFFERING OF COMMON STOCK
 
     In February 1996, the Company completed an underwritten public offering of
2.4 million shares of Common Stock on behalf of certain holders of Common Stock
and warrants to purchase Common Stock. The Company received net proceeds of $4
million from the exercise of the warrants and $5 million from the issuance of an
additional 0.2 million shares upon the exercise of the underwriters'
over-allotment option.
 
PREFERRED STOCK REPURCHASE
 
     In February 1996, the Company's Board of Directors authorized the Company
to implement a $50 million stock repurchase program for the Preferred Stock. In
the first and second quarters of 1996, the Company repurchased approximately
592,000 shares of Preferred Stock at an aggregate cost of approximately $12
million and an aggregate premium of approximately $3 million above their
original issue price.
 
COMMON STOCK REPURCHASE
 
     In July 1996, the Company's Board of Directors authorized the Company to
implement a $100 million stock repurchase program for the Common Stock. In the
third quarter of 1996, the Company repurchased approximately 1,653,000 shares of
Common Stock at an aggregate cost of approximately $37 million.
 
PREFERRED STOCK EXCHANGED FOR COMMON STOCK
 
     In May 1996, the Company's stockholders approved a charter amendment that
gave the holders of Preferred Stock the opportunity to convert their shares into
Common Stock if they desired to do so. Holders of Preferred Stock were allowed,
but were not required, to convert their shares of Preferred Stock into Common
Stock on a share-for-share basis, subject to a value limitation of $22.475 per
share. Holders of Preferred Stock were allowed to exercise the optional
conversion right at any time until the close of business on August 16, 1996. At
August 16, 1996, approximately 7,679,000 shares of Preferred Stock had been
converted into a like number of shares of Common Stock. Shares of Preferred
Stock not converted continue to have exactly the same rights as they had prior
to the optional conversion period.
 
9. COMMITMENTS AND CONTINGENCIES
 
OPERATING LEASE COMMITMENT
 
     In March 1996, the Company entered into a lease agreement with an
unaffiliated entity ("Second Lessor") with respect to an ammonia plant to be
constructed at the Trinidad plant site ("Second Trinidad Plant Lease"). Upon
completion of construction, the Second Lessor will lease the plant to a
subsidiary of the Company. The annual lease payments under the Second Trinidad
Plant Lease are expected to be
 
                                       11

                     ARCADIAN CORPORATION AND SUBSIDIARIES
 
      NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
                                  (UNAUDITED)
 
approximately $21 million. The initial seven-year lease term is renewable for an
additional five-year term, subject to certain conditions. If the Second Trinidad
Plant Lease is not renewed or is otherwise terminated, a subsidiary of the
Company may be required to make a residual termination payment equal to 85% of
the estimated $285 million total cost of the project. In addition, the Company
has an option to purchase the plant during the term of the Second Trinidad Plant
Lease for a price approximating its fair market value at the date of exercise.
The plant is expected to be operational in 1998.
 
LAKE CHARLES PLANT
 
     In connection with an incident at its Lake Charles plant in 1992, the
Company is contesting penalties proposed by the United States Occupational
Safety and Health Administration ("OSHA") totaling $4 million. The OSHA legal
proceeding to date has generally been favorable to the Company. While management
and legal counsel believe that any civil penalty ultimately paid by the Company
will be substantially less than the remaining $4 million penalty proposed by
OSHA, they cannot predict with certainty the outcome of this proceeding.
 
     In September 1996, the Company's liability insurers negotiated preliminary
settlements of substantially all of the civil litigation arising from the Lake
Charles incident. The settlements, which in the aggregate are within the policy
limits of the Company's liability insurance, are subject to the negotiation and
execution of definitive settlement agreements and, with respect to the class
action civil litigation, approval as to fairness by the court. There remain
three lawsuits against the Company arising from the incident, which were brought
by former employees at the Lake Charles plant who allege that they were
wrongfully terminated by the Company following the incident. Management and
legal counsel believe that these lawsuits are without merit, and that there will
be no material adverse effect on the Company upon their resolution.
 
PORT AUTHORITY OF NEW YORK AND NEW JERSEY
 
     On March 13, 1996, the Company, two other nitrogen producers, and up to 30
unidentified parties were named as defendants in a lawsuit filed in the name of
the Port Authority of New York and New Jersey (the "Port Authority") in New
Jersey state court. The lawsuit was actually filed by attorneys hired by the
Port Authority's subrogated insurance carriers. The Port Authority's insurers
are seeking to recover damages allegedly incurred as a result of the explosion
at the World Trade Center in New York City on February 26, 1993. The Port
Authority's insurers allege in their complaint that the two other named
defendants and one or more unidentified parties (as manufacturers of ammonium
nitrate), the Company and one or more unidentified parties (as producers of
urea), and one or more unidentified makers of nitric acid are liable under
various tort theories for unspecified property damages, business interruption
losses, lost rent and other damages allegedly incurred by the Port Authority as
a result of the World Trade Center explosion. The Company and the other
defendants have removed the case to federal court in New Jersey. Pending the
resolution of the Port Authority's motion to disqualify its insurers' counsel,
the court stayed substantive proceedings in the lawsuit. That motion was
resolved by an order dated September 23, 1996, and substantive proceedings are
scheduled to resume on November 26, 1996. Although neither the Port Authority
nor its subrogated insurers have alleged or otherwise revealed the amount of
damages sought from the Company in the lawsuit, the Port Authority stated in an
affidavit submitted to the court in support of its motion to disqualify its
insurers' counsel that as of April 9, 1996, the Port Authority had submitted to
its insurers claims relating to the explosion totaling approximately $340
million, of which the insurers had paid approximately $160 million. The Company
is unaware of any basis for liability and intends to vigorously defend the
lawsuit.

STOCKHOLDERS LITIGATION
 
     On August 5, 1996, the Company and Freeport-McMoRan Inc. ("Freeport")
signed a non-binding letter of intent for the combination of their businesses
into a newly formed company. Following the public announcement on August 7,
1996, of the Company's execution of the letter of intent, five lawsuits were
filed in Delaware state court on behalf of a purported class of all stockholders
of the Company other than the defendants and their affiliates. The Company and
some or all of its directors (including one former director, who was
subsequently dismissed from the lawsuits) were named as defendants in the
lawsuits. On September 2, 1996, the Company entered into an Agreement and Plan
of Merger (the "Merger Agreement") with Potash Corporation of Saskatchewan Inc.
("PCS") and PCS Nitrogen, Inc., a wholly owned subsidiary of PCS ("Merger Sub"),
providing for the acquisition of the Company by PCS through the merger of the
Company with and into Merger Sub (the "Merger"). On September 5, 1996, following
the public announcement of the proposed Merger on September 3, 1996, an amended
complaint (the "Amended Complaint") was filed in two of the five lawsuits. PCS
is named as an additional defendant in the Amended Complaint, but PCS has
informed the Company that PCS has not yet received service of process. The
Amended Complaint alleges generally that the defendants acted improperly in
causing the Company to enter into the Merger Agreement, and seeks an injunction
preventing the Merger, unspecified monetary damages, and other relief. On
September 16, 1996, the court signed an order consolidating all five lawsuits
and ordering that the Amended Complaint serve as the complaint in the
consolidated action. The Company and its directors have agreed to formally
respond to the Amended Complaint on or before November 27, 1996. The Company is
unaware of any basis for liability, and the defendants intend to vigorously
defend the lawsuit.
 
10. SUBSEQUENT EVENTS
 
COMMON STOCK DIVIDEND
 
     On November 14, 1996, the Company paid a cash dividend on the Common Stock
in the amount of $0.10 per share or approximately $4 million in the aggregate to
holders of record at the close of business on November 4, 1996.
 
PREFERRED STOCK DIVIDEND
 
     On November 14, 1996, the Company paid a cash dividend on the Preferred
Stock in the amount of $0.3681 per share or approximately $2 million in the
aggregate to holders of record at the close of business on November 4, 1996.
 
11. MERGER
 
TERMINATION OF POTENTIAL BUSINESS COMBINATION WITH FREEPORT
 
     On September 2, 1996, the Company terminated its previously disclosed
non-binding letter of intent dated August 5, 1996, with Freeport regarding their
potential business combination.
 
PROPOSED ACQUISITION BY PCS
 
     On September 2, 1996, the Company, PCS and Merger Sub entered into the
Merger Agreement pursuant to which, subject to the satisfaction or waiver of
certain conditions, PCS will acquire the Company through the Merger. In the
Merger, subject to adjustment and to certain exceptions, each outstanding share
of Common Stock, including each share resulting from the mandatory conversion of
the outstanding shares of Preferred Stock immediately prior to the Merger, will
be converted into the right to receive $12.25 in cash and a fraction of a common
share of PCS expected to have a market value of between $12.75 and $14.75. The
obligations of the Company and PCS to consummate the Merger are subject to
various conditions, including

the condition that the holders of a majority of the outstanding shares of Common
Stock and Preferred Stock, voting together as a single class, vote in favor of
the approval of the Merger Agreement. The Company expects to hold a special
meeting of stockholders in January 1997, at which the stockholders will consider
and vote upon the Merger Agreement. If the necessary stockholder vote is
obtained and all other conditions are satisfied or waived, the Company expects
that the Merger will be consummated shortly thereafter.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS
 
RESULTS OF OPERATIONS
 
     Because of the seasonal nature of the Company's business, the results of
operations for the periods presented are not necessarily indicative of the
results for a full fiscal year.
 
NINE MONTHS ENDED SEPTEMBER 30, 1996, COMPARED TO NINE MONTHS ENDED SEPTEMBER
30, 1995
 
     For the nine months ended September 30, 1996, the Company generated net
income of $116 million, or $2.49 per common share, compared to net income of $55
million, or $2.44 per common share, for the same period last year. Operating
income decreased $14 million for the nine months ended September 30, 1996, from
the prior year period.
 
     For the nine months ended September 30, 1996, compared to the same period
last year, net sales decreased $25 million or 3%, of which 4% was related to
decreased selling prices, partially offset by a 1% increase in sales volumes.
Lower ammonia selling prices were partially offset by an increase in the selling
prices of nitrogen solutions. Higher sales volumes reflect increased sales
tonnage of low margin purchased ammonia for resale.
 
     Gross profit decreased $20 million for the reasons noted above. Gross
profit as a percentage of net sales decreased from 28% for the nine months ended
September 30, 1995, to 27% for the nine months ended September 30, 1996,
partially as a result of the lower ammonia selling prices. The per unit natural
gas cost included in cost of sales remained relatively flat.
 
     Selling, general and administrative expenses as a percentage of net sales
decreased from 5% for the nine months ended September 30, 1995, to 4% for the
nine months ended September 30, 1996.
 
     Net interest expense decreased 33% to $30 million in the nine months ended
September 30, 1996, compared to $44 million for the same period in 1995,
reflecting the improvement in the Company's net debt.
 
     The non-controlling interest in earnings of the Partnership in 1995
reflected the approximately 55% interest of the Preference Unitholders in the
net earnings of the Partnership prior to the August 1995 Merger.
 
     The income tax provision increased $20 million for the nine months ended
September 30, 1996, compared to the same period in 1995. The increase primarily
reflects the increase in the Partnership's income allocable to the Corporation
as a result of the August 1995 Merger, partially offset by a reduction in the
Trinidad statutory income tax rate. The effective income tax rate for the nine
months ended September 30, 1996, was approximately 35%.
 
THREE MONTHS ENDED SEPTEMBER 30, 1996, COMPARED TO THREE MONTHS ENDED SEPTEMBER
30, 1995
 
     For the three months ended September 30, 1996, the Company generated net
income of $23 million, or $0.51 per common share, compared to net income of $20
million, or $0.58 per common share, for the same period last year. Operating
income decreased $9 million for the three months ended September 30, 1996, from
the prior year period.
 
     For the three months ended September 30, 1996, compared to the same period
last year, net sales increased $24 million or 9%, of which 14% was related to
increased sales volumes, partially offset by a 5% decrease in selling prices.
Higher sales volumes reflect increased sales tonnage of low margin purchased
ammonia for resale and increased sales tonnage of nitrogen solutions. Lower
ammonia and nitrogen solutions selling prices were partially offset by an
increase in the selling prices of urea.
 
     Gross profit decreased $11 million for the reasons noted above. Gross
profit as a percentage of net sales decreased from 26% in the third quarter of
1995 to 21% in the third quarter of 1996 partially as a result of the lower
ammonia and nitrogen solutions selling prices. The per unit natural gas cost
included in cost of sales increased approximately 5% from 1995.
 
     Selling, general and administrative expenses as a percentage of net sales
decreased from 6% for the three months ended September 30, 1995, to 5% for the
three months ended September 30, 1996.
 
                                       15
<PAGE>   17
 
     Net interest expense decreased 38% to $10 million in the third quarter of
1996 compared to $16 million for the same period in 1995, reflecting the
improvement in the Company's net debt.
 
     The non-controlling interest in earnings of the Partnership in 1995
reflected the approximately 55% interest of the Preference Unitholders in the
net earnings of the Partnership prior to the August 1995 Merger.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  Operating Activities
 
     Net cash provided by (used for) operating activities was $151 million and
$249 million for the nine months ended September 30, 1996 and 1995, and ($2)
million and $53 million for the three months ended September 30, 1996 and 1995,
respectively. At September 30, 1996 and 1995, working capital, net of restricted
reserve accounts, was $304 million and $252 million, respectively.
 
  Investing Activities
 
     Net cash used for investing activities of $56 million and $15 million for
the nine months ended September 30, 1996 and 1995, and $27 million and $6
million for the three months ended September 30, 1996 and 1995, respectively,
reflects primarily capital expenditures, rotational plant maintenance cost, and
an investment of $11 million in an ammonia terminal joint venture in the second
quarter of 1996.
 
  Financing Activities
 
     Net cash used for financing activities was $83 million and $121 million for
the nine months ended September 30, 1996 and 1995, and $55 million and $15
million for the three months ended September 30, 1996 and 1995, respectively.
The nine months ended September 30, 1995, amount reflected a $61 million
reduction in the outstanding balance under the revolving credit facility.
 
     At September 30, 1996, there was no outstanding balance on the Company's
$100 million revolving credit facility, and the amount available for borrowing
in the form of loans and letters of credit, after considering outstanding and
committed letters of credit of $40 million, was $60 million.
 
     Management believes that its present working capital position, combined
with projected cash flows from operations and available borrowing capacity, will
be sufficient to meet the Company's remaining 1996 and anticipated 1997 cash
requirements for operating needs, projected capital expenditures, and dividend
payments on the Company's Mandatorily Convertible Preferred Stock, Series A
("Preferred Stock").
 
     From 1997 through 2000, the Company's principal long-term liquidity
requirements will focus on maturities of long-term debt. Excluding the revolving
credit facility, maturities of long-term debt will range from $15 million to $18
million in 1997 through 2000. Cash from operations is expected to be sufficient
for the payment of all such maturities of long-term debt.
 
     The Company's 10 3/4% Series B Senior Notes due 2005, its First Mortgage
Notes, and the revolving credit facility contain provisions restricting
distributions on the equity interests of Arcadian Partners, L.P., Arcadian
Fertilizer, L.P., and certain other subsidiaries in the event that certain
financial covenants are not met. Management believes that such subsidiaries will
continue to meet all such financial covenants for the foreseeable future.
 
     In February 1996, the Company completed an underwritten public offering of
2.4 million shares of Common Stock on behalf of certain holders of Common Stock
and warrants to purchase Common Stock. The Company received net proceeds of $4
million from the exercise of the warrants and $5 million from the issuance of an
additional 0.2 million shares upon the exercise of the underwriters'
over-allotment option.
 
     In February 1996, the Company's Board of Directors authorized the Company
to implement a stock repurchase program for the Preferred Stock. The Board of
Directors authorized the Company to spend up to $50 million in repurchasing
shares of Preferred Stock from time to time as management deems appropriate. In
the first and second quarters of 1996, the Company repurchased approximately
592,000 shares of Preferred Stock at an aggregate cost of approximately $12
million and an aggregate premium of approximately $3 million above their
original issue price. The timing of Preferred Stock repurchases is dependent
upon many factors, including the price, the Company's financial condition, and
general economic and market factors.

     In July 1996, the Company's Board of Directors authorized the Company to
implement a stock repurchase program for the Common Stock. The Board of
Directors authorized the Company to spend up to $100 million in repurchasing
shares of Common Stock from time to time as management deems appropriate. In the
third quarter of 1996, the Company repurchased approximately 1,653,000 shares of
Common Stock at an aggregate cost of approximately $37 million. The timing of
Common Stock repurchases is dependent upon many factors, including the price,
the Company's financial condition, and general economic and market factors.
 
     In May 1996, the Company's stockholders approved a charter amendment that
gave the holders of Preferred Stock the opportunity to convert their shares into
Common Stock if they desired to do so. Holders of Preferred Stock were allowed,
but were not required, to convert their shares of Preferred Stock into Common
Stock on a share-for-share basis, subject to a value limitation of $22.475 per
share. Holders of Preferred Stock were allowed to exercise the optional
conversion right at any time until the close of business on August 16, 1996. At
August 16, 1996, approximately 7,679,000 shares of Preferred Stock had been
converted into a like number of shares of Common Stock. Shares of Preferred
Stock not converted continue to have exactly the same rights as they had prior
to the optional conversion period. Based on the Company's existing dividend
policies, the conversion of such shares from Preferred Stock to Common Stock
will result in a net decrease of approximately $8 million in the Company's
annual dividend requirements.
 
     In February, May, August and November 1996, the Company paid cash dividends
on the Common Stock in the aggregate amounts of approximately $2 million ($0.05
per share), $3 million ($0.10 per share), $3 million ($0.10 per share), and $4
million ($0.10 per share), respectively.
 
     In February, May, August and November 1996, the Company paid cash dividends
on the Preferred Stock in the aggregate amounts of approximately $5 million
($0.3682 per share), $5 million ($0.3681 per share), $5 million ($0.3681 per
share) and $2 million ($0.3681 per share), respectively.
 
  Operating Lease Commitment
 
     In March 1996, the Company entered into a lease agreement with an
unaffiliated entity ("Second Lessor") with respect to an ammonia plant to be
constructed at the Trinidad plant site ("Second Trinidad Plant Lease"). Upon
completion of construction, the Second Lessor will lease the plant to a
subsidiary of the Company. The annual lease payments under the Second Trinidad
Plant Lease are expected to be approximately $21 million. The initial seven-year
lease term is renewable for an additional five-year term, subject to certain
conditions. If the Second Trinidad Plant Lease is not renewed or is otherwise
terminated, a subsidiary of the Company may be required to make a residual
termination payment equal to 85% of the estimated $285 million total cost of the
project. In addition, the Company has an option to purchase the plant during the
term of the Second Trinidad Plant Lease for a price approximating its fair
market value at the date of exercise. The plant is expected to be operational in
1998.
 
  Lake Charles Plant
 
     In connection with an incident at its Lake Charles plant in 1992, the
Company is contesting penalties proposed by the United States Occupational
Safety and Health Administration ("OSHA") totaling $4 million. The OSHA legal
proceeding to date has generally been favorable to the Company. While management
and legal counsel believe that any civil penalty ultimately paid by the Company
will be substantially less than the remaining $4 million penalty proposed by
OSHA, they cannot predict with certainty the outcome of this proceeding.
 
     In September 1996, the Company's liability insurers negotiated preliminary
settlements of substantially all of the civil litigation arising from the Lake
Charles incident. The settlements, which in the aggregate are within the policy
limits of the Company's liability insurance, are subject to the negotiation and
execution of definitive settlement agreements and, with respect to the class
action civil litigation, approval as to fairness by the court. There remain
three lawsuits against the Company arising from the incident, which were brought
by former employees at the Lake Charles plant who allege that they were
wrongfully terminated by the Company
 
                                       17
<PAGE>   19
 
following the incident. Management and legal counsel believe that these lawsuits
are without merit, and that there will be no material adverse effect on the
Company upon their resolution.
 
  Port Authority of New York and New Jersey
 
     On March 13, 1996, the Company, two other nitrogen producers, and up to 30
unidentified parties were named as defendants in a lawsuit filed in the name of
the Port Authority of New York and New Jersey (the "Port Authority") in New
Jersey state court. The lawsuit was actually filed by attorneys hired by the
Port Authority's subrogated insurance carriers. The Port Authority's insurers
are seeking to recover damages allegedly incurred as a result of the explosion
at the World Trade Center in New York City on February 26, 1993. The Port
Authority's insurers allege in their complaint that the two other named
defendants and one or more unidentified parties (as manufacturers of ammonium
nitrate), the Company and one or more unidentified parties (as producers of
urea), and one or more unidentified makers of nitric acid are liable under
various tort theories for unspecified property damages, business interruption
losses, lost rent and other damages allegedly incurred by the Port Authority as
a result of the World Trade Center explosion. The Company and the other
defendants have removed the case to federal court in New Jersey. Pending the
resolution of the Port Authority's motion to disqualify its insurers' counsel,
the court stayed substantive proceedings in the lawsuit. That motion was
resolved by an order dated September 23, 1996, and substantive proceedings are
scheduled to resume on November 26, 1996. Although neither the Port Authority
nor its subrogated insurers have alleged or otherwise revealed the amount of
damages sought from the Company in the lawsuit, the Port Authority stated in an
affidavit submitted to the court in support of its motion to disqualify its
insurers' counsel that as of April 9, 1996, the Port Authority had submitted to
its insurers claims relating to the explosion totaling approximately $340
million, of which the insurers had paid approximately $160 million. The Company
is unaware of any basis for liability and intends to vigorously defend the
lawsuit.
 
  Stockholders Litigation
 
     On August 5, 1996, the Company and Freeport-McMoRan Inc. ("Freeport")
signed a non-binding letter of intent for the combination of their businesses
into a newly formed company. Following the public announcement on August 7,
1996, of the Company's execution of the letter of intent, five lawsuits were
filed in Delaware state court on behalf of a purported class of all stockholders
of the Company other than the defendants and their affiliates. The Company and
some or all of its directors (including one former director, who was
subsequently dismissed from the lawsuits) were named as defendants in the
lawsuits. On September 2, 1996, the Company entered into an Agreement and Plan
of Merger (the "Merger Agreement") with Potash Corporation of Saskatchewan Inc.
("PCS") and PCS Nitrogen, Inc., a wholly owned subsidiary of PCS ("Merger Sub"),
providing for the acquisition of the Company by PCS through the merger of the
Company with and into Merger Sub (the "Merger"). On September 5, 1996, following
the public announcement of the proposed Merger on September 3, 1996, an amended
complaint (the "Amended Complaint") was filed in two of the five lawsuits. PCS
is named as an additional defendant in the Amended Complaint, but PCS has
informed the Company that PCS has not yet received service of process. The
Amended Complaint alleges generally that the defendants acted improperly in
causing the Company to enter into the Merger Agreement, and seeks an injunction
preventing the Merger, unspecified monetary damages, and other relief. On
September 16, 1996, the court signed an order consolidating all five lawsuits
and ordering that the Amended Complaint serve as the complaint in the
consolidated action. The Company and its directors have agreed to formally
respond to the Amended Complaint on or before November 27, 1996. The Company is
unaware of any basis for liability, and the defendants intend to vigorously
defend the lawsuit.
 
  Termination of Potential Business Combination with Freeport
 
     On September 2, 1996, the Company terminated its previously disclosed
non-binding letter of intent dated August 5, 1996, with Freeport regarding their
potential business combination.

  Proposed Acquisition by PCS
 
     On September 2, 1996, the Company, PCS and Merger Sub entered into the
Merger Agreement pursuant to which, subject to the satisfaction or waiver of
certain conditions, PCS will acquire the Company through the Merger. In the
Merger, subject to adjustment and to certain exceptions, each outstanding share
of Common Stock, including each share resulting from the mandatory conversion of
the outstanding shares of Preferred Stock immediately prior to the Merger, will
be converted into the right to receive $12.25 in cash and a fraction of a common
share of PCS expected to have a market value of between $12.75 and $14.75. The
obligations of the Company and PCS to consummate the Merger are subject to
various conditions, including the condition that the holders of a majority of
the outstanding shares of Common Stock and Preferred Stock, voting together as a
single class, vote in favor of the approval of the Merger Agreement. The Company
expects to hold a special meeting of stockholders in January 1997, at which the
stockholders will consider and vote upon the Merger Agreement. If the necessary
stockholder vote is obtained and all other conditions are satisfied or waived,
the Company expects that the Merger will be consummated shortly thereafter.

                          AGREEMENT AND PLAN OF MERGER
 
     This Agreement and Plan of Merger (the "Agreement"), dated as of September
2, 1996, is by and among Potash Corporation of Saskatchewan Inc., a Saskatchewan
corporation ("PCS"), Arcadian Corporation, a Delaware corporation ("Arcadian"),
and PCS Nitrogen, Inc., a Delaware corporation and a wholly-owned subsidiary of
PCS ("Merger Sub").
 
                              W I T N E S S E T H
 
     WHEREAS, the Boards of Directors of PCS and Arcadian have deemed that it is
advisable and in the best interests of the security holders of PCS and Arcadian,
respectively, that PCS acquire Arcadian pursuant to the merger of Arcadian with
and into Merger Sub as set forth herein; and
 
     WHEREAS, in connection with the Merger described herein, Arcadian will
exercise the "Common Conversion Option" set forth in the Certificate of
Designation (the "Certificate of Designation") creating Arcadian's Mandatorily
Convertible Preferred Stock, Series A ("Arcadian Preferred Stock"), so that (a)
all shares of Arcadian Preferred Stock outstanding immediately prior to the
Merger will be converted into shares of Arcadian Common Stock immediately prior
to the Merger as provided in the Certificate of Designation, and (b) all such
shares of Arcadian Common Stock resulting from such conversion of the Arcadian
Preferred Stock will be treated in the Merger identically to all other shares of
Arcadian Common Stock outstanding immediately prior to the Merger; and
 
     WHEREAS, the parties hereto intend that the merger of Arcadian with and
into Merger Sub shall be accomplished in a manner that will qualify as a
reorganization under Section 368(a)(2)(D) of the Internal Revenue Code of 1986,
as amended (the "Code").
 
     NOW, THEREFORE, in consideration of the foregoing and the agreements and
conditions specified in this Agreement, the parties hereto agree as follows:
 
                                   ARTICLE 1
 
                                   THE MERGER
 
     SECTION 1.01. The Merger. (a) At the Effective Time, Arcadian shall be
merged (the "Merger") with and into Merger Sub in accordance with the provisions
of the General Corporation Law of the State of Delaware, as amended ("Delaware
Law"), whereupon the separate existence of Arcadian shall cease, and Merger Sub
shall be the surviving corporation (the "Surviving Corporation"). From and after
the Effective Time, the Surviving Corporation shall possess all the rights,
privileges, powers and franchises and be subject to all of the restrictions,
disabilities and duties of Arcadian and Merger Sub, all as provided under
Delaware Law.
 
     (b) Pursuant to the Merger, at the Effective Time:
 
          (i) each share of Arcadian Common Stock outstanding immediately prior
     to the Effective Time shall, except as otherwise provided in Section
     1.01(b)(ii), Section 1.05, Section 1.08, or Section 1.09, be converted into
     cash equal to the Per Share Cash Amount and that fraction of a share of PCS
     Common Stock equal to the Per Share Stock Amount;
 
          (ii) each share of Arcadian Common Stock held by Arcadian or any
     Subsidiary of Arcadian or owned by PCS or any Subsidiary of PCS immediately
     prior to the Effective Time shall be canceled, and no payment shall be made
     with respect thereto;
 
          (iii) each share of common stock of Merger Sub outstanding immediately
     prior to the Effective Time shall be converted into and become one share of
     common stock of the Surviving Corporation with the same rights, powers and
     privileges as the shares so converted and shall constitute the only
     outstanding share of capital stock of the Surviving Corporation; except for
     such additional common stock as will be issued to PCS by Surviving
     Corporation in consideration of PCS agreeing to deliver the Merger Shares
     to the Exchange Agent. The share certificates evidencing the common stock
     of Merger Sub shall be canceled and a new share certificate of the
     Surviving Corporation shall be issued to PCS.
 
                                        1
<PAGE>   7
 
          (iv) for purposes hereof, the term "Per Share Cash Amount" shall mean
     $12.25; the term "Per Share Stock Amount" shall mean the number of shares
     (or a fraction thereof) of PCS Common Stock (expressed as a decimal and
     with the result rounded up or down to the nearest one one-thousandth,
     0.0005 being rounded up to 0.001) equal to:
 
             (A) if the Final PCS Common Stock Price is at least $72.00 but not
        greater than $83.25, then 0.17713;
 
             (B) if the Final PCS Common Stock Price is less than $72.00, then
        the lesser of (1) 0.19615 and (2) the quotient of (x) $12.75 divided by
        (y) the Final PCS Common Stock Price; and
 
             (C) if the Final PCS Common Stock Price is greater than $83.25,
        then the greater of (1) 0.16389 and (2) the quotient of (x) $14.75
        divided by (y) the Final PCS Common Stock Price;
 
          (v) for purposes hereof, the term "Final PCS Common Stock Price" shall
     mean the quotient obtained by dividing (A) the sum of the averages of the
     daily high and low trading prices of the PCS Common Stock on the New York
     Stock Exchange (the "NYSE") for each trading day during the Valuation
     Period by (B) the number of trading days in the Valuation Period; the term
     "Valuation Period" shall mean the 20 consecutive days on which shares of
     PCS Common Stock are traded on the NYSE ending on the second business day
     immediately prior to the anticipated Effective Time; and the term
     "Determination Date" shall mean the last day of the Valuation Period; and
 
          (vi) for purposes hereof, the term "dollars" and the symbol "$" shall
     both mean United States dollars.
 
     SECTION 1.02. Exchange Agent; Payment of Merger Consideration.
 
     (a) As soon as reasonably practicable after the Effective Time, and subject
to the provisions of Section 1.09, (i) PCS shall deposit or cause to be
deposited with ChaseMellon Shareholder Services, L.L.C. or such other
institution as may be designated by PCS, as exchange agent (including any
co-exchange agent, the "Exchange Agent"), for the benefit of the holders of
Arcadian Common Stock (collectively, the "Holders"), certificates representing
the number of whole shares of PCS Common Stock (collectively, the "Merger
Shares") to which each Holder has become entitled pursuant to Section 1.01, and
(ii) Merger Sub shall deposit (A) cash equal to the aggregate Per Share Cash
Amount to which the Holders have become entitled pursuant to Section 1.01 (the
"Merger Cash"), and (B) the cash to which the Holders are entitled as provided
in Section 1.05 (the Merger Shares, the Merger Cash and any cash to which a
Holder is entitled as provided in Section 1.05 together being the "Merger
Consideration"). In consideration of PCS agreeing to deliver the Merger Shares
to the Exchange Agent, Surviving Corporation shall issue to PCS common stock of
Surviving Corporation having a value equal to the Merger Shares.
 
     (b) As soon as reasonably practicable after the Effective Time, and in any
event within 30 days after the Effective Time, the Exchange Agent shall mail to
each Holder of record as of the Effective Time, a form of letter of transmittal
and instructions for use in effecting the surrender of the certificates
representing Arcadian Common Stock or Arcadian Preferred Stock, as the case may
be (each such certificate, an "Old Certificate"), in exchange for the Merger
Consideration. Upon the proper delivery and surrender to the Exchange Agent of
an Old Certificate, together with a duly completed and executed letter of
transmittal, the record holder of such Old Certificate shall be entitled to
receive, and the Exchange Agent (pursuant to irrevocable instructions from PCS)
shall deliver to such record holder, in exchange therefor, subject to Section
1.09, (i) a certificate representing the Merger Shares to which such Holder
shall have become entitled pursuant to Section 1.01, (ii) the Merger Cash to
which such Holder shall have become entitled pursuant to Section 1.01, and (iii)
if applicable, cash in lieu of fractional shares as provided in Section 1.05.
Any Old Certificate delivered to the Exchange Agent with a duly completed and
executed letter of transmittal shall forthwith be canceled. Until so delivered,
each Old Certificate shall, after the Effective Time, represent for all purposes
only the right to receive the Merger Consideration as set forth in this
Agreement. No interest will be paid or will accrue on any portion of the Merger
Consideration payable on the surrender of an Old Certificate. Any Holder whose
Old Certificate has been lost or destroyed may nevertheless obtain the Merger
Consideration into which the
 
                                        2
<PAGE>   8
 
Arcadian Common Stock, represented by such lost Old Certificate would have been
converted pursuant to Section 1.01, provided such Holder delivers to PCS and the
Exchange Agent a statement certifying such loss or destruction and providing for
indemnity reasonably satisfactory to PCS and the Exchange Agent against any loss
or expense either of them may incur as a result of such lost or destroyed Old
Certificate being thereafter surrendered to the Exchange Agent or PCS. In the
event of a transfer of ownership of any Arcadian Common Stock which is not
registered in the transfer records of Arcadian, the Merger Consideration may be
delivered to a transferee if the Old Certificate representing such Arcadian
Common Stock so transferred is presented to the Exchange Agent, accompanied by
all documents required to evidence and effect such transfer and by evidence that
any applicable transfer taxes have been paid or are not payable.
 
     (c) No dividends payable with respect to any Merger Shares shall be paid to
persons entitled to receive such Merger Shares until such persons have
surrendered their Old Certificates (or certification with respect to lost or
destroyed Old Certificates) to the Exchange Agent in accordance with Section
1.02(b). After such surrender, there shall be paid to the person in whose name
the Merger Shares shall be issued any dividends on such Merger Shares that have
a record date prior to such surrender. If the payment date for such dividend is
after the date of such surrender, payment shall be made on such payment date. In
no event will any person entitled to receive Merger Shares be entitled to
interest on any dividend declared with respect to Merger Shares.
 
     (d) Any of the Old Certificates, and any certification with respect to lost
or destroyed Old Certificates, that have not been surrendered or delivered to
the Exchange Agent within six months after the Effective Time may be delivered
to PCS, and any Holder who has not theretofore complied with Section 1.02(b)
shall thereafter look only to PCS for payment of the Merger Consideration.
Notwithstanding the foregoing, neither the Exchange Agent nor any party hereto
shall be liable for any cash or securities delivered to a public official
pursuant to applicable abandoned property, escheat or similar laws.
 
     (e) All deliveries and payments in respect of Arcadian Common Stock that
are made in accordance with the terms hereof shall be deemed to have been made
in full satisfaction of all rights pertaining to such securities, except as may
be otherwise required by law.
 
     SECTION 1.03. Transfers after the Effective Time. No transfers of Arcadian
Common Stock or Arcadian Preferred Stock shall be made on the transfer books of
the Surviving Corporation at or after the Effective Time.
 
     SECTION 1.04. Withholding. PCS shall be entitled to deduct and withhold
from the consideration otherwise payable pursuant to this Agreement to any
Holder such amounts as PCS may be required to deduct and withhold with respect
to the making of such payment under the Code or any provision of state, local or
foreign tax law. To the extent that such amounts are so withheld by PCS, such
withheld amounts shall be treated for all purposes of this Agreement as having
been paid to the Holder in respect of whom such deduction and withholding were
made.
 
     SECTION 1.05. Fractional Shares. No fractional shares of PCS Common Stock
shall be issued in connection with the Merger, but in lieu thereof each holder
of Arcadian Common Stock otherwise entitled to a fractional share of PCS Common
Stock (considering all Old Certificates held of record by such holder together)
will be entitled to receive a cash payment (rounded up or down to the nearest
$.01, $.005 being rounded up to $.01) in an amount equal to such fractional part
of a share of PCS Common Stock multiplied by the Final PCS Common Stock Price.
 
     SECTION 1.06. Options, SARs, CESARs and Restricted Stock. (a) As soon as
reasonably practicable after receiving written instructions from PCS and before
the Effective Time, Arcadian shall take all necessary and appropriate actions to
implement the provisions of clause (1) or (3) of Section 6(j) of Arcadian's
Stock Option Plan, as amended (the "Option Plan"), with respect to the
outstanding options to purchase shares of Arcadian Common Stock (the "Options")
granted under the Option Plan. Arcadian and PCS understand and agree that
subject to certain conditions set forth in the Option Plan, (i) said clause (1)
of Section 6(j) permits Arcadian to accelerate the time at which the then
outstanding Options may be exercised in full for a limited period of time on or
before a specified date (which, in the case of the Merger, will permit the
holders of the
 
                                        3
<PAGE>   9
 
Options (the "Optionees") to participate in the Merger with the shares of
Arcadian Common Stock received upon the exercise of such Options) to be fixed by
the Committee (as defined in the Option Plan), after which specified date all
unexercised Options and all rights of the Optionees thereunder shall terminate,
and (ii) said clause (3) permits Arcadian to require the mandatory surrender to
Arcadian of the then outstanding Options, as of a date before or not later than
sixty (60) days after the Effective Time as specified by the Committee, in which
event such Options shall be canceled and Arcadian shall pay to each Optionee an
amount of cash equal to the excess of the fair market value (as determined in
accordance with the Option Plan) of the aggregate shares of Arcadian Common
Stock subject to such Option over the aggregate option price of such shares.
 
     (b) As soon as reasonably practicable before the Effective Time, Arcadian
shall take all necessary and appropriate actions to further amend Arcadian's
Stock Appreciation Rights Plan, as amended (the "SAR Plan"), to provide that at
the Effective Time, each stock appreciation right unit granted under the SAR
Plan ("SAR") that is outstanding immediately prior to the Effective Time shall
be converted into (i) cash equal to the Per Share Cash Amount less the
applicable Award Price (as set forth in the applicable SAR agreement) of such
SAR and (ii) a fraction of a share of PCS Common Stock equal to the Per Share
Stock Amount or cash of equal value.
 
     (c) As soon as reasonably practicable before the Effective Time, Arcadian
shall take all necessary and appropriate actions to amend Arcadian's Cash
Equivalent Stock Appreciation Rights Plan (the "CESAR Plan") to provide that at
the Effective Time, each cash equivalent stock appreciation right unit granted
under the CESAR Plan ("CESAR") that is outstanding immediately prior to the
Effective Time shall be converted into (i) cash equal to the Per Share Cash
Amount less $6.67 and (ii) a fraction of a share of PCS Common Stock equal to
the Per Share Stock Amount or cash of equal value.
 
     (d) Immediately prior to the Effective Time, all restrictions relating to
all shares of Arcadian Common Stock theretofore granted pursuant to Arcadian's
Restricted Stock Plan (the "Restricted Stock Plan") shall lapse, and all
conditions to the holders' receipt of such shares free of any such restrictions
shall be deemed satisfied. At the Effective Time, each share of Arcadian Common
Stock theretofore granted pursuant to the Restricted Stock Plan shall be
converted into the Merger Consideration pursuant to Section 1.01(b).
 
     SECTION 1.07. Certain Adjustments. If at any time during the period between
the date of this Agreement and the Effective Time, any change in the outstanding
shares of capital stock of Arcadian shall occur, including by reason of any
reclassification, recapitalization, stock split or combination, exchange or
readjustment of shares, or any stock dividend thereon with a record date during
such period, the Merger Consideration shall be appropriately adjusted; provided,
however, that none of (a) the exercise between the date of this Agreement and
the Effective Time of Stock Options outstanding on the date of this Agreement,
(b) the issuance of shares of Arcadian Common Stock pursuant to the Restricted
Stock Plan, (c) the conversion of shares of Arcadian Preferred Stock in or at
any time prior the Merger, shall require any such adjustment.
 
     SECTION 1.08. Dissenting Shares. Notwithstanding any of the foregoing
provisions of this Article 1, shares of Arcadian Common Stock and Arcadian
Preferred Stock outstanding immediately prior to the Effective Time and held by
a Holder who has not voted in favor of the Merger or consented thereto in
writing and who has demanded appraisal for such shares in accordance with
Delaware Law shall not be converted into a right to receive the Merger
Consideration, unless such Holder fails to perfect or withdraws or otherwise
loses his right to appraisal. If after the Effective Time such holder fails to
perfect or withdraws or loses his or her right to appraisal, such shares of
Arcadian Common Stock shall be treated as if they had been converted as of the
Effective Time into a right to receive the Merger Consideration. Arcadian shall
give PCS prompt notice of any demands received by Arcadian for appraisal of
shares of Arcadian Common Stock or Arcadian Preferred Stock, and PCS shall have
the right to participate in all negotiations and proceedings with respect to
such demands.
 
     SECTION 1.09. Cash/Stock Adjustment. In the event that holders of Arcadian
Common Stock, in the aggregate, would not receive PCS Common Stock in the Merger
without the adjustment described herein, in an amount representing at least
47.94% of the Total Consideration, then the Per Share Stock Amount shall be
increased and the Per Share Cash Amount shall be decreased by the same dollar
value, so that at least 47.94% of the Total Consideration is represented by PCS
Common Stock. As used herein, the term "Total
 
                                        4
<PAGE>   10
 
Consideration" means the sum of (a) the aggregate Merger Consideration (but
excluding the value of shares of Arcadian Common Stock as to which appraisal
rights have been demanded and not waived or otherwise lost), (b) the value of
the shares of Arcadian Common Stock as to which appraisal rights have been
demanded and not waived or otherwise lost, and (c) any amount paid in redemption
of Arcadian Common Stock and Arcadian Preferred Stock, other than redemptions
undertaken in the ordinary course of business and not in contemplation of the
Merger, within one year prior to the effective date of the Merger. Solely for
purposes of the foregoing computation, shares of PCS Common Stock to be received
by any Five Percent Holder (other than any Five Percent Holder who has delivered
to Arcadian a statement satisfactory to Arcadian to the effect that such Five
Percent Holder then has no intention to dispose of the shares of PCS Common
Stock to be received by such Five Percent Holder in the Merger for a period of
two years after the effective date of the Merger) shall be considered to be
cash, and shall not be considered to be shares of PCS Common Stock. As used
herein, the term "Five Percent Holder" means any stockholder of Arcadian who,
immediately prior to the Effective Time, is the owner of five percent or more of
(a) the aggregate number of shares of Arcadian Common Stock then outstanding
plus (b) the aggregate number of shares of Arcadian Common Stock into which the
Arcadian Preferred Stock then outstanding will be converted immediately prior to
the Merger pursuant to Arcadian's exercise of the Common Conversion Option.

Merger Sub at the Effective Time shall be the directors of the Surviving
Corporation, and (ii) the officers of Merger Sub at the Effective Time shall be
the officers of the Surviving Corporation.

Subsidiaries is a corporation or partnership duly organized, validly existing
and in good standing under the laws of its jurisdiction of organization and has
all requisite power and authority to carry on its business as now conducted.
Each of PCS and its Subsidiaries is duly qualified to do business and is in good
standing in each jurisdiction in which the business it is conducting, or the
operation, ownership or leasing of its properties, makes such qualification
necessary, other than in such jurisdictions where the failure to so qualify
would not, individually or in the aggregate, have a Material Adverse Effect on
PCS. PCS has furnished to Arcadian complete and correct copies of its charter
documents and By-laws.
 
     (b) As used in this Agreement:
 
          (i) "Subsidiary" means, as to any Person, any corporation or other

     Adverse Effect on the business, assets, condition (financial or otherwise)
     or results of operations of such Person and its Subsidiaries, taken as a
     whole, which effect shall be measured net of, and only after giving the
     Person the benefit of, any payments under any insurance, indemnity,
     reimbursement, contribution, compensation or other similar rights which
     reduce, offset, compensate or otherwise limit the impact thereof on the
     Person and its Subsidiaries.

approved and adopted this Agreement and the transactions contemplated hereby,
including the Merger. This Agreement has been duly executed and delivered by PCS
and Merger Sub and constitutes the valid and binding agreements of PCS and
Merger Sub, enforceable against PCS and Merger Sub in accordance with its terms,
subject to (a) bankruptcy, insolvency, moratorium
 
                                        6

is entitled under any provision of any agreement, contract or other instrument
binding upon PCS or any of its Subsidiaries, or (d) result in the creation or
imposition of any Lien on any asset of PCS or any of its Subsidiaries, except
for such contraventions, conflicts or violations referred to in clause (b) or
defaults or rights of termination, cancellation or acceleration referred to in
clause (c) or creations or impositions of any Lien referred to in clause (d)
that would not, individually or in the aggregate, have a Material Adverse Effect
on PCS. For purposes of this Agreement, "Lien" means, with respect to any asset,
any mortgage, lien, pledge, charge, security interest or encumbrance of any kind
in respect of such asset.
 
     SECTION 4.05. Capitalization. (a) As of the date hereof, the authorized
capital stock of PCS consists of an unlimited number of common shares without
par value (the "PCS Common Stock"), and an unlimited number of preferred shares,
issuable in series without par value. At the close of business on July 31, 1996,

1,288,325 shares of PCS Common Stock were reserved for issuance pursuant to
options issued by PCS, and (iii) no preferred shares were issued or outstanding.
All outstanding shares of capital stock of PCS have been validly issued and are

shares to be issued under PCS's Dividend Reinvestment Plan (the "PCS DRIP"), as
of the date hereof, there are no options, warrants, calls, rights, commitments
or agreements to which PCS or any of its Subsidiaries is a party or by which it
is bound, obligating PCS or any of its Subsidiaries to issue, deliver, sell,
purchase, redeem or acquire, or cause to be issued, delivered, sold, purchased,
redeemed or acquired, additional shares of capital stock or other voting
securities of PCS or any of its Subsidiaries or obligating PCS or any of its
Subsidiaries to grant, extend or enter into any such option, warrant, call,
right, commitment or agreement.
 
     (b) Except as disclosed in any of the PCS Disclosure Documents, all of the
outstanding capital stock of, or other ownership interests in, each Subsidiary
of PCS is owned by PCS, directly or indirectly, free and clear of any Lien and
free of any other limitation or restriction (including any restriction on the
right to vote, sell or otherwise dispose of such capital stock or other
ownership interests).
 
     SECTION 4.06. Disclosure Documents. PCS has previously furnished to
Arcadian true and complete copies of:
 
          (a) PCS Annual Reports to Shareholders for each of the years ended

                                        7
<PAGE>   13

Securities Laws and, to the extent applicable, the Securities Act and the
Exchange Act, and (ii) did not contain any untrue statement of a material fact

Disclosure Documents (including any related notes and schedules) fairly present
the financial position of PCS and its consolidated Subsidiaries as of the dates
thereof and the results of operations and cash flows for the periods or as of

adjustments), in each case in accordance with past practice and generally
accepted accounting principles in Canada ("Canadian GAAP") consistently applied
during the periods involved (except as otherwise disclosed in the notes

regulation of any governmental entity (provided that no representation or

violations as would not, individually or in the aggregate, have a Material
Adverse Effect on PCS.
 
     SECTION 4.08. No Undisclosed Liabilities. As of June 30, 1996, neither PCS

whether or not accrued, contingent or otherwise, that would be required by
Canadian GAAP to be reflected on a consolidated balance sheet of PCS and its
Subsidiaries (including the notes thereto), except (a) liabilities or
obligations reflected in any of the PCS Disclosure Documents and (b) liabilities
or obligations which would not, individually or in the aggregate, have a
Material Adverse Effect on PCS.

proceeding pending or, to the best knowledge of PCS, threatened against or
affecting PCS or any of its Subsidiaries that is reasonably likely to have a
Material Adverse Effect on PCS, or (iii) judgment, decree, injunction, or, to

arbitrator outstanding against PCS or any of its Subsidiaries, that is
reasonably likely to have a Material Adverse Effect on PCS.

judgments, injunctions, consent agreements, permits and governmental
restrictions relating to pollution or protection of human health and safety or
the environment (including, without limitation, ambient air, surface water,
ground water, land surface and subsurface strata) (collectively, "Environmental
Laws"), except for non-compliance which would not, individually or in the
aggregate, have a Material Adverse Effect on PCS and, to the best knowledge of
PCS, there are no existing or reasonably foreseeable circumstances, conditions,
events or occurrences that are
 
                                        8
<PAGE>   14
 
reasonably likely to materially prevent or interfere with such compliance in the
next three years, (b) PCS and each of its Subsidiaries have obtained and
maintained in effect (or are in the process of obtaining) all permits, licenses,
certificates and other governmental authorizations required under applicable
Environmental Laws ("Environmental Permits") with respect to their properties,
assets, businesses, and operations except where the failure to do so would not
have a Material Adverse Effect on PCS; (c) neither PCS nor any of its
Subsidiaries has received written notice of, or, to the best knowledge of PCS,
is the subject of, any action, cause of action, claim, investigation, demand,
notice, request for information, complaint, suit or proceeding by any Person
alleging liability under or in connection with or non-compliance with any
Environmental Law, including, without limitation, toxic tort, nuisance, trespass
and similar claims (collectively, "Environmental Claim"), which is reasonably
likely to, individually or in the aggregate, have a Material Adverse Effect on
PCS; (d) as of June 30, 1996, neither PCS nor any of its Subsidiaries had any
liabilities or obligations of any nature, whether accrued, contingent or
otherwise, and whether relating to PCS, any of its Subsidiaries or any

of its Subsidiaries owns, leases or operates or, since January 1, 1986, has
owned, leased or operated, any real property in New Jersey or Connecticut, or
conducts or, since January 1, 1986, has conducted, any operations in New Jersey

Statement or any amendments or supplements thereto, at the time of the mailing
of the Proxy Statement or any amendments or supplements thereto, at the time of
the Special Meeting, and at the Effective Time, or, in the case of the
Registration Statement, at the time it becomes effective, contain any untrue
statement of a material fact relating to PCS, its Subsidiaries or the Merger, or
omit to state any material fact required to be stated therein relating to PCS,
its Subsidiaries or the Merger, or necessary in order to make the statements
therein relating to PCS, its Subsidiaries or the Merger, in light of the
circumstances under which they were made, not misleading. The Proxy Statement
will comply as to form in all material respects with the provisions of the
Exchange Act, and the Registration Statement will comply as to form in all
material respects with the provisions of the Securities Act. The letter to
stockholders, notice of meeting, proxy statement/prospectus and forms of proxies

Meeting, and any schedules required to be filed with the SEC in connection
therewith, are collectively referred to herein as the "Proxy Statement".

corporate powers and, except for approval by Arcadian's stockholders in
connection with the consummation of the Merger, have been duly authorized by all
necessary corporate action. Without limiting the generality of the foregoing,
the Board of Directors of Arcadian has unanimously adopted a resolution adopting
and approving this Agreement. The affirmative vote of a majority of the
outstanding shares of Arcadian Common Stock and Arcadian Preferred Stock
entitled to vote thereon, voting as a single class, is the only vote of any
class or series of Arcadian's capital stock necessary to approve and adopt this
Agreement and the transactions contemplated hereby. This Agreement has been duly
executed and delivered by Arcadian and constitutes a valid and binding agreement
of Arcadian, enforceable against Arcadian in accordance with its terms, subject
to (a) bankruptcy, insolvency, moratorium and other similar laws now or
hereafter in effect relating to or affecting creditors' rights generally and (b)
general principles of equity (regardless of whether considered in a proceeding
at law or in equity).
 
     SECTION 5.03. Governmental Authorization. The execution, delivery and
performance by Arcadian of this Agreement and the consummation of the Merger by
Arcadian require no action by or in respect of, or filing with, any governmental
body, agency, official or authority other than (a) the filing of a Certificate
of Merger in accordance with Delaware Law; (b) compliance with any applicable
requirements of the HSR Act; (c) compliance with any applicable requirements of
the Securities Act and the Exchange Act; and (d) compliance with any applicable
requirements of Environmental Law relating to Environmental Permits and any
other applicable environmental protection clearances.
 
     SECTION 5.04. Non-Contravention. Except as previously disclosed in writing
to PCS or as disclosed in any of the Arcadian SEC Documents, the execution,
delivery and performance by Arcadian of this Agreement and the consummation by
Arcadian of the transactions contemplated hereby do not and will not (a)
contravene or conflict with the Restated Certificate of Incorporation, as
amended, or the Amended and Restated Bylaws of Arcadian, (b) assuming compliance
with the matters referred to in Section 5.03, contravene or conflict with or
constitute a violation of any provision of any law, ordinance, regulation,
judgment, injunction, order or decree binding upon or applicable to Arcadian or
any of its Subsidiaries, (c) constitute a default (or an event which with
notice, the lapse of time or both would become a default) under or give rise to
a right of termination, cancellation or acceleration of any right or obligation
to which Arcadian or any of its Subsidiaries is entitled under any provision of
any agreement, contract or other instrument binding upon Arcadian or any of its
Subsidiaries, or (d) result in the creation or imposition of any Lien on any
asset of Arcadian or any of its Subsidiaries, except for such contraventions,
conflicts or violations referred to in clause (b) or defaults or rights of
termination, cancellation or acceleration referred to in clause (c) or creations
or impositions of any Lien referred to in clause (d) that would not,
individually or in the aggregate, have a Material Adverse Effect on Arcadian.
 
     SECTION 5.05. Capitalization. (a) As of the date hereof, the authorized
capital stock of Arcadian consists of 150,000,000 shares of common stock, par
value $0.01 per share (the "Arcadian Common Stock"), and 50,000,000 shares of
preferred stock, par value $0.01 per share. At the close of business on August
29, 1996, (i) 38,540,261 shares of Arcadian Common Stock were issued and
outstanding, (ii) 7,680,640 shares of Arcadian Common Stock were reserved for
issuance pursuant to options granted or available for grant by Arcadian,
warrants issued by Arcadian, pursuant to the Restricted Stock Plan, and upon
conversion of the Arcadian Preferred Stock, and (iii) 5,534,157 shares of
Arcadian Preferred Stock were issued and outstanding and 12,593 shares of
Arcadian Preferred Stock were reserved for issuance. All outstanding shares of
capital stock of Arcadian have been validly issued and are fully paid and
nonassessable. Except as set forth above, as of the date hereof, there are no
options, warrants, calls, rights, commitments or agreements to which Arcadian or
any of its Subsidiaries is a party or by which it is bound, obligating Arcadian
or any of its Subsidiaries to issue, deliver, sell, purchase, redeem or acquire,
or cause to be issued, delivered, sold, purchased, redeemed or acquired,
additional shares of capital stock or other voting securities of Arcadian or any
of its Subsidiaries or obligating Arcadian or any of its Subsidiaries to grant,
extend or enter into any such option, warrant, call, right, commitment or
agreement.
 
     (b) Except as disclosed in Schedule 5.05 or any of the Arcadian SEC
Documents, all of the outstanding capital stock of, or other ownership interests
in, each Subsidiary of Arcadian is owned by Arcadian, directly or
 
                                       11
<PAGE>   17
 
indirectly, free and clear of any Lien and free of any other limitation or
restriction (including any restriction on the right to vote, sell or otherwise
dispose of such capital stock or other ownership interests).
 
     SECTION 5.06. SEC Documents. Arcadian has previously furnished to PCS true
and complete copies of:
 
          (a) Arcadian Annual Reports on Form 10-K filed with the SEC for each
     of the years ended December 31, 1993 through 1995;
 
          (b) Arcadian Quarterly Reports on Form 10-Q filed with the SEC for the
     quarters ended March 31 and June 30, 1996;
 
          (c) each definitive proxy statement filed by Arcadian with the SEC
     since December 31, 1993;
 
          (d) each final prospectus filed by Arcadian with the SEC since
     December 31, 1993, except any final prospectus on Form S-8; and
 
          (e) all Current Reports on Form 8-K filed by Arcadian with the SEC
     since December 31, 1995.
 
     As of their respective dates, such reports, proxy statements and
prospectuses (collectively, the "Arcadian SEC Documents") (i) complied as to
form in all material respects with the applicable requirements of the Securities
Act and the Exchange Act and (ii) did not contain any untrue statement of a
material fact or omit to state a material fact required to be stated therein or
necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading. The audited consolidated financial
statements and unaudited consolidated interim financial statements included in
the Arcadian SEC Documents (including any related notes and schedules) fairly
present the financial position of Arcadian and its consolidated Subsidiaries as
of the dates thereof and the results of operations and cash flows for the
periods or as of the dates then ended (subject, where appropriate, to normal
year-end adjustments), in each case in accordance with past practice and
generally accepted accounting principles in the United States ("GAAP")
consistently applied during the periods involved (except as otherwise disclosed
in the notes thereto). Since December 31, 1993, Arcadian has timely filed all
reports, registration statements and other filings required to be filed by it
with the SEC under rules and regulations of the SEC.
 
     SECTION 5.07. Compliance with Laws. The businesses of Arcadian and its
Subsidiaries are not being conducted in violation of any law, ordinance or
regulation of any governmental entity (provided that no representation or
warranty is made in this Section 5.07 with respect to Environmental Laws),
except as disclosed in any of the Arcadian SEC Documents and except for such
violations as would not, individually or in the aggregate, have a Material
Adverse Effect on Arcadian.
 
     SECTION 5.08. No Undisclosed Liabilities. As of June 30, 1996, neither
Arcadian nor any of its Subsidiaries had any liabilities or obligations of any
nature, whether or not accrued, contingent or otherwise, that would be required
by GAAP to be reflected on a consolidated balance sheet of Arcadian and its
Subsidiaries (including the notes thereto), except for (a) the liabilities or
obligations reflected in any of the Arcadian SEC Documents, (b) the liabilities
and obligations described on Schedule 5.08, and (c) the liabilities or
obligations which would not, individually or in the aggregate, have a Material
Adverse Effect on Arcadian.
 
     SECTION 5.09. Litigation. Except as previously disclosed in writing to PCS
or as disclosed in any of the Arcadian SEC Documents, there is no (i) class
action litigation pending or, to the best knowledge of Arcadian, threatened
against or affecting Arcadian or any of its Subsidiaries, (ii) other suit,
action or proceeding pending or, to the best knowledge of Arcadian, threatened
against or affecting Arcadian or any of its Subsidiaries that is reasonably
likely to have a Material Adverse Effect on Arcadian or (iii) judgment, decree,
injunction, rule or order of any governmental entity or arbitrator outstanding
against Arcadian or any of its Subsidiaries that is reasonably likely to have a
Material Adverse Effect on Arcadian.
 
     SECTION 5.10. Environmental Matters. Except as previously disclosed in
writing to PCS, as described in the Arcadian SEC Documents, or as disclosed in
Schedule 5.10, (a) Arcadian and each of its Subsidiaries are in compliance with
all applicable Environmental Laws except for non-compliance which would not,
individually or in the aggregate, have a Material Adverse Effect on Arcadian
and, to the best knowledge of
 
                                       12
<PAGE>   18
 
Arcadian, there are no existing or reasonably foreseeable circumstances,
conditions, events or occurrences that are reasonably likely to materially
prevent or interfere with such compliance in the next three years; (b) Arcadian
and each of its Subsidiaries have obtained and maintained in effect, or are in
the process of obtaining, all Environmental Permits required with respect to
their properties, assets, businesses, and operations, except where the failure
to do so would not, individually or in the aggregate, have a Material Adverse
Effect on Arcadian; (c) neither Arcadian nor any of its Subsidiaries has
received written notice of, or, to the best knowledge of Arcadian, is the
subject of, any Environmental Claim which is reasonably likely to, individually
or in the aggregate, have a Material Adverse Effect on Arcadian; (d) as of June
30, 1996, neither Arcadian nor any of its Subsidiaries had any liabilities or
obligations of any nature, whether accrued, contingent or otherwise, and whether
relating to Arcadian, any of its Subsidiaries or any predecessor entities of
Arcadian or any of its Subsidiaries, arising under or relating to any
Environmental Law or Environmental Claim, except for liabilities or obligations
which would not, individually or in the aggregate, be reasonably expected to
result in losses (excluding capital expenditures) in excess of $5,000,000 during
the five-year period from the date hereof or (ii) individually or in the
aggregate, have a Material Adverse Effect on Arcadian; and (e) neither Arcadian
nor any of its Subsidiaries owns, leases or operates or, since January 1, 1986,
has owned, leased or operated, any real property in New Jersey or Connecticut,
or conducts or, since January 1, 1986, has conducted, any operations in New
Jersey or Connecticut.
 
     SECTION 5.11. ERISA. (a) Schedule 5.11 contains a list identifying each
"employee benefit plan", as defined in Section 3(3) of the Employee Retirement
Income Security Act of 1974 ("ERISA"), which (i) is subject to any provision of
ERISA and (ii) is maintained, administered or contributed to by Arcadian or any
Subsidiary of Arcadian and covers any employee or former employee of Arcadian or
any Subsidiary of Arcadian or under which Arcadian or any Subsidiary of Arcadian
has any liability. Copies of such plans (and, if applicable, related trust
agreements and/or insurance contracts) and all amendments thereto and written
interpretations thereof have been furnished to PCS together with (A) the three
most recent annual reports (Form 5500 including, if applicable, Schedule A or
Schedule B thereto or both) prepared in connection with any such plan, (B) the
most recent annual actuarial valuation report prepared in connection with any
such plan, and (c) the summary plan description (as defined in ERISA), if any,
and, all modifications thereto, prepared in connection with any such plan. Such
plans are referred to collectively herein as the "Arcadian Employee Plans". The
only Arcadian Employee Plans which individually or collectively would constitute
an "employee pension benefit plan (the "Pension Plans"), as defined in Section
3(2) of ERISA, are identified as such in the list referred to above.
 
     (b) Except as set forth in Schedule 5.11, no Arcadian Employee Plan (i)
constitutes a "Multiemployer Plan", as defined in Section 3(37) of ERISA (a
"Multiemployer Plan"), (ii) is maintained in connection with any trust described
in Section 501(c)(9) of the Code, or (iii) is subject to Title IV of ERISA.
Neither Arcadian nor any ERISA Affiliate, as defined below, of Arcadian has (A)
engaged in, or is a successor to an entity that has engaged in, a transaction
described in Sections 4069 or 4212(c) of ERISA or (B) incurred, or reasonably
expects to incur prior to the Effective Time, (1) any liability under Title IV
of ERISA arising in connection with the termination of, or a complete or partial
withdrawal from, any plan covered or previously covered by Title IV of ERISA or
(2) any liability under Section 4971 of the Code that in either case could
become a liability of PCS or any of its Affiliates after the Effective Time.
Nothing done or omitted to be done and no transaction or holding of any asset
under or in connection with any Arcadian Employee Plan has or will make Arcadian
or any Subsidiary of Arcadian, or any officer or director of Arcadian or any
Subsidiary of Arcadian, subject to any liability under Title I of ERISA or
liable for any tax pursuant to Section 4975 of the Code that could have a
Material Adverse Effect on Arcadian. As of December 31, 1995, the present value
of all benefits accrued under each Arcadian Employee Plan subject to Title IV of
ERISA, other than a Multiemployer Plan (an "Arcadian Title IV Plan"), determined
on an ongoing basis using the assumptions used in the most recently prepared
annual actuarial valuation report, did not exceed the fair market value of the
assets of such Arcadian Title IV Plan as of such date (excluding for these
purposes any accrued but unpaid contributions) by more than $1,000,000. As of
December 31, 1995, there was no aggregate unfunded liability of Arcadian and any
Subsidiary of Arcadian in respect of all Arcadian Employee Plans or Arcadian
Benefit Arrangements described under Sections 4(b)(5) or 401 (a)(1) of ERISA,
computed using reasonable actuarial assumptions and determined as if all
benefits under such plans were vested and payable as
 
                                       13
<PAGE>   19
 
of such date. All contributions or payments required to be made or accrued on
behalf of any Arcadian Employee Plan maintained by Arcadian, any of its
Subsidiaries, or any ERISA Affiliate, before the Effective Time, under the terms
of any Arcadian Employee Plan, will have been made or accrued by Arcadian, or by
its Subsidiaries, or any ERISA Affiliate, as applicable, by the Effective Time.
No Arcadian Employee Plan subject to Section 412 of the Code has incurred any
"accumulated funding deficiency" (as defined in ERISA), whether or not waived.
For purposes of this Section 5.11. "ERISA Affiliate" shall mean any entity which
is considered one employer with Arcadian under Section 4001 of ERISA or Section
414 of the Code.
 
     (c) With respect to each Arcadian Employee Plan which is intended to be
qualified under Section 401(a) of the Code, Arcadian has received a favorable
determination letter that the plan is so qualified and that each trust forming a
part thereof is exempt from tax pursuant to Section 501(a) of the Code and, to
the best knowledge of Arcadian, no event has occurred since the date of such
determination that would adversely affect such qualification and exception.
Arcadian has furnished to PCS copies of the most recent Internal Revenue Service
determination letters with respect to each such Plan. Each Arcadian Employee
Plan has been maintained in all material respects in compliance with its terms
and with the requirements prescribed by any and all statutes, orders, rules and
regulations, including but not limited to ERISA and the Code, which are
applicable to such Plan.
 
     (d) Except as set forth in Schedule 5.11, there is no contract, agreement,
plan or arrangement covering any employee or former employee of Arcadian or any
Subsidiary of Arcadian that, individually or collectively, could give rise to
the payment of any amount that would not be deductible pursuant to the terms of
Sections 162(a)(1), 162(m) or 280G of the Code.
 
     (e) Schedule 5.11 contains a list of each employment, severance or other
similar contract, arrangement or policy and each plan or arrangement (written or
oral) providing for insurance coverage (including any self-insured
arrangements), workers' compensation, disability benefits, supplemental
unemployment benefits, vacation benefits, retirement benefits or for deferred
compensation, profit-sharing, bonuses, stock options, stock appreciation or
other forms of incentive compensation or post-retirement insurance, compensation
or benefits which (i) is not an Arcadian Employee Plan, (ii) is entered into,
maintained or contributed to, as the case may be, by Arcadian or any of its
Subsidiaries and (iii) covers any United States employee or former employee of
Arcadian or any of its Subsidiaries. Such contracts, plans and arrangements as
are described above, copies (or descriptions, in the case of oral arrangements)
of all of which have been furnished or made available previously to PCS are
referred to collectively herein as the "Arcadian Benefit Arrangements". Each
Arcadian Benefit Arrangement has been maintained in substantial compliance with
its terms and with the requirements prescribed by any and all statutes, orders,
rules and regulations that are applicable to such Arcadian Benefit Arrangement.
 
     (f) Neither Arcadian nor any Subsidiary of Arcadian has any current or
projected liability in respect of post-employment or post-retirement health or
medical or life insurance benefits for retired, former or current employees of
Arcadian or any Subsidiary of Arcadian, except as required to avoid excise tax
under Section 4980B of the Code. No condition exists that would prevent Arcadian
or any Subsidiary of Arcadian from amending or terminating any Arcadian Employee
Plan or Arcadian Benefit Arrangement providing health or medical benefits in
respect of any active or former employee of Arcadian or any Subsidiary other
than limitations imposed under the terms of a collective bargaining agreement.
 
     (g) Except as set forth in Schedule 5.11 or as described in Section
5.13(j), there has been no amendment to, written interpretation or announcement
(whether or not written) by Arcadian or any of its Subsidiaries relating to, or
change in employee participation or coverage under, any Arcadian Employee Plan
or Arcadian Benefit Arrangement which would increase materially the expense of
maintaining such Arcadian Employee Plan or Arcadian Benefit Arrangement above
the level of the expense incurred in respect thereof for the fiscal year ended
on December 31, 1995.
 
     (h) Except as set forth in Schedule 5.11, neither Arcadian nor any
Subsidiary of Arcadian is a party to or subject to (i) any employment contract
or arrangement providing for annual future cash compensation of $250,000 or more
with any officer, director or employee, or (ii) any collective bargaining
agreement or union contract.
 
                                       14
<PAGE>   20
 
     (i) Arcadian has provided to PCS a list of (a) the names, titles, annual
salaries and other compensation of all officers of Arcadian or its Subsidiaries
and all other employees of Arcadian or its Subsidiaries whose annual base salary
exceeds $250,000 and (b) the wage rates for non-salaried employees of Arcadian
and its Subsidiaries (by classification). None of the employees referred to in
clause (a) and no other key employee of Arcadian or its Subsidiaries has
disclosed to Arcadian and its Subsidiaries that he or she intends to resign or
retire as a result of the transactions contemplated by this Agreement, or
otherwise for any other reason within one year after the date of this Agreement.
 
     (j) Arcadian and its Subsidiaries are in compliance with all currently
applicable laws respecting employment and employment practices, terms and
conditions of employment and wages and hours, and are not engaged in any unfair
labor practice, failure to comply with which or engagement in which, as the case
may be, would reasonably be expected to have a Material Adverse Effect on
Arcadian. There is no unfair labor practice complaint pending or, to the best
knowledge of Arcadian, threatened against Arcadian or any Subsidiary of Arcadian
before the National Labor Relations Board which would reasonably be expected to
have a Material Adverse Effect on Arcadian.
 
     (k) Schedule 5.11 identifies each employment, severance or other similar
contract, arrangement or policy and each plan or arrangement (written or oral)
providing for insurance coverage (including any self-insured arrangements),
workers' compensation, disability benefits, supplemental unemployment benefits,
vacation benefits, retirement benefits or for deferred compensation,
profit-sharing, bonuses, stock options, stock appreciation or other forms of
incentive compensation or post-retirement insurance, compensation or benefits
which (i) is not an Arcadian Employee Plan or Arcadian Benefit Arrangement, (ii)
is entered into, maintained or contributed to, as the case may be, by Arcadian
or any of its Subsidiaries and (iii) covers any employee or former employee of
Arcadian or any of its Subsidiaries (each an "Arcadian International Plan").
Arcadian has furnished to PCS copies of each Arcadian International Plan. Each
Arcadian International Plan has been maintained in substantial compliance with
its terms and with the requirements prescribed by any and all applicable
statutes, orders, rules and regulations (including any special provisions
relating to qualified plans where such Plan was intended to so qualify) and has
been maintained in good standing with applicable regulatory authorities. There
has been no amendment to, written interpretation of or announcement (whether or
not written) by Arcadian or any Subsidiary relating to, or change in employee
participation or coverage under, any Arcadian International Plan that would
increase materially the expense of maintaining such International Plan above the
level of expense incurred in respect thereof for the most recent fiscal year
ended prior to the date hereof. According to the actuarial assumptions and
valuations most recently used for the purpose of funding each Arcadian
International Plan (or, if the same has no such assumptions and valuations or is
unfunded, according to reasonable actuarial assumptions and valuations), as of
December 31, 1994, the total amount or value of the funds available under such
Plan to pay benefits accrued thereunder or segregated in respect of such accrued
benefits, together with any reserve or accrual with respect thereto, was not
less than the present value of all benefits (actual or contingent) accrued as of
such date of all participants and past participants therein in respect of which
Arcadian or any Subsidiary has or would have after the Closing any obligation.
From and after the Closing Date, PCS and its Affiliates will get the full
benefit of any such funds, accruals or reserves, to the extent permitted by
applicable law.
 
     (l) Except as previously disclosed in writing to PCS, there is no issue
with respect to any Arcadian Employee Plan or Benefit Arrangement that is now,
or within the last twelve months has been, under examination by the Internal
Revenue Service or the Department of Labor and no audit with respect to any
Arcadian Employee Plan or Benefit Arrangement by either the Internal Revenue
Service or the Department of Labor has occurred. There are no pending
investigations by any governmental or regulatory agency or authority involving
or relating to any Arcadian Employee Plan or Benefit Arrangement, no threatened
or pending claims (except for claims for benefit payable in the normal
operations of the Arcadian Employee Plans or Benefit Arrangement), suits or
proceedings against any Arcadian Employee Plan or Benefit Arrangement or
asserting any rights or claims to benefits under any Arcadian Employee Plan or
Benefit Arrangement which could reasonably be expected to have a Material
Adverse Effect on Arcadian.
 
     (m) Neither Arcadian nor any of its Subsidiaries nor any ERISA Affiliate
has provided, or is required to provide, security to any Arcadian Employee Plan
pursuant to Section 401(a)(29) of the Code.
 
                                       15

     SECTION 5.12. Proxy Statement; Registration Statement. Neither the Proxy
Statement nor the Registration Statement will, in the case of the Proxy
Statement or any amendments thereof or supplements thereto, at the time of the
mailing of the Proxy Statement or any amendments or supplements thereto, at the
time of the Special Meeting, and at the Effective Time, or, in the case of the
Registration Statement, at the time it becomes effective, contain any untrue
statement of a material fact relating to Arcadian, its Subsidiaries or the
Merger or omit to state any material fact required to be stated therein relating
to Arcadian, its Subsidiaries or the Merger or necessary in order to make the
statements therein relating to Arcadian, its Subsidiaries or the Merger, in
light of the circumstances under which they were made, not misleading. The Proxy
Statement will comply as to form in all material respects with the provisions of
the Exchange Act.
 
     SECTION 5.13. Absence of Certain Changes. Except as disclosed elsewhere
herein or in any of the Arcadian SEC Documents, as set forth on Schedule 5.13,
or as specifically permitted by Section 6.01, since June 30, 1996, Arcadian and
its Subsidiaries have conducted their business in the ordinary course consistent
with past practice and there has not been:
 
          (a) any event, occurrence or facts which has had or is reasonably
     expected to have a Material Adverse Effect on Arcadian;
 
          (b) any declaration, setting aside or payment of any dividend or other
     distribution with respect to any shares of capital stock of Arcadian (other
     than payment of Arcadian's regular quarterly dividend on Arcadian Common
     Stock in an amount not exceeding $0.10 per share and on the Arcadian
     Preferred Stock), or any repurchase, redemption or other acquisition by
     Arcadian or any Subsidiary of Arcadian of any outstanding shares of capital
     stock or other securities of, or other ownership interests in, Arcadian,
     which repurchase, redemption or other acquisition, individually or in the
     aggregate, is material to Arcadian and its Subsidiaries, taken as a whole;
 
          (c) any amendment of any term of any outstanding security of Arcadian
     or any Subsidiary of Arcadian;
 
          (d) any incurrence, assumption or guarantee by Arcadian or any

     and on terms consistent with past practices;
 
          (e) any creation or assumption by Arcadian or any Subsidiary of
     Arcadian of any Lien on any material asset other than in the ordinary
     course of business consistent with past practices;
 
          (f) any making of any loan, advance or capital contribution to or
     investment in any Person other than (i) loans, advances or capital
     contributions to or investments in Subsidiaries of Arcadian, (ii)
     investments in securities consistent with past practice or (iii) other
     loans, advances, capital contributions or investments in an aggregate
     amount not exceeding $25,000,000;

     covered by insurance) affecting the business or assets of Arcadian or any
     Subsidiary of Arcadian which, individually or in the aggregate, is or may
     reasonably be expected to have a Material Adverse Effect on Arcadian;
 
          (h) except in the ordinary course of business consistent with past
     practice, any transaction or commitment made, or any contract or agreement
     entered into, by Arcadian or any Subsidiary of Arcadian relating to its
     assets or business (including, without limitation, the acquisition or
     disposition of any assets) or any relinquishment by Arcadian or any
     Subsidiary of Arcadian of any contract, license or other right, other than
     transactions, commitments, contracts or agreements contemplated by this
     Agreement;
 
          (i) any change in any method of accounting or accounting principle or

     "Severance Program"), a copy of which has been furnished to PCS, (iii) for
     Arcadian's execution and delivery of certain Employment Agreements with the

     termination, severance or other plan, agreement, trust, fund, policy or
     arrangement for the benefit of any of its directors, officers or employees;
     or (D) any increase in the compensation or benefits of any other employees
     or payment of any benefit not required by any plan or arrangement as in
     effect on June 30, 1996;
 
          (k) except such contracts as would not be material to Arcadian and its
     Subsidiaries as a whole, any entry by Arcadian or any of its Subsidiaries
     into any contract limiting the right of Arcadian or any of its Subsidiaries
     at any time on or after the date of this Agreement or PCS or any of its
     Subsidiaries or affiliates at or after the Effective Time, to engage in, or
     to compete with any Person in, any business; or
 
          (l) any entry by Arcadian or any of its Subsidiaries into any
     acquisition or joint venture which is material to Arcadian and its
     Subsidiaries, taken as a whole.
 
     SECTION 5.14. Taxes. (a) All Tax Returns required to be filed (taking into
account all extensions heretofore granted) on or before the Effective Time by or
on behalf of Arcadian or any of its Subsidiaries have been filed with the
appropriate Taxing Authorities within the time and in the manner prescribed by
law, other than those Tax Returns the failure of which to file in the aggregate
would not have a Material Adverse Effect on Arcadian.
 
     (b) All such Tax Returns are true, correct and complete in all material
respects. Except as listed on Schedule 5.14, no such Tax Return for tax years
beginning after September 1, 1988 contains a disclosure statement under Section
6662(d)(2)(B)(ii)(I) of the Code or any similar provision of state, local or
foreign law. For each taxable year of Arcadian and its Subsidiaries beginning
after December 31, 1989, Arcadian will furnish or make available (or cause to be
furnished or made available) to PCS or its representatives, immediately after
the date hereof, true and complete copies of all Tax Returns filed by Arcadian
and its Subsidiaries.
 
     (c) All Taxes shown to be due and payable by Arcadian and any of its
Subsidiaries on all such Tax Returns have been paid, or withheld or collected
and remitted or deposited in full to or with the appropriate Taxing Authorities,
and Arcadian and its Subsidiaries have made appropriate provision in their June
30, 1996 financial statements for any Taxes owed but not yet paid.

against Arcadian and any of its Subsidiaries have expired, (ii) no deficiency
payment of any Taxes for any period has been asserted or raised by any Taxing
Authority which remains unpaid at the date hereof except for deficiencies which
would not have a Material Adverse Effect on Arcadian, (iii) no adjustment,
assessment, reassessment or collection for Taxes applicable to Arcadian or any
of its Subsidiaries has been proposed or, to the knowledge of Arcadian and its
Subsidiaries, threatened by any Taxing Authorities, except for adjustments,
assessments, reassessments or collections that would not, individually, or in
the aggregate, have a Material Adverse Effect on Arcadian; (iv) no closing
agreement is in effect for any period with respect to any Tax applicable to
Arcadian or any of its Subsidiaries; (v) no power of attorney has been granted
by Arcadian or any of its Subsidiaries with respect to any matter relating to
Taxes, which is currently in force; (vi) any material adjustment or material
assessment of federal Taxes prior to the Effective Time which is required to be
reported by Arcadian or any of its Subsidiaries to the appropriate Taxing
Authorities has been reported and any additional amount due and payable with
respect thereto has
 
                                       17
<PAGE>   23
 
been paid in full; and (vii) there is, and there will be, no valid basis for the
Internal Revenue Service to request an extension of the statute of limitation
with respect to any federal income Tax Return of Arcadian or any of its
Subsidiaries beyond the limitations period which generally expires three years
after the filing of any such Tax Return as a result of a more than 25% omission
from gross income in connection with such Tax Return. Schedule 5.14 lists all
Tax Returns filed with respect to Arcadian and any of its Subsidiaries for the
taxable periods beginning on or after January 1, 1989 that have been audited,
and indicates those Tax Returns that currently are the subject of audit.
 
     (e) Except for Tax Returns required to be filed with respect to the 1995
taxable year, neither Arcadian nor any of its Subsidiaries has requested any
extension of time within which to file any Tax Return which has not yet been
filed.
 
     (f) There are no material Liens applicable to either Arcadian or any of its
Subsidiaries or any property or assets of Arcadian or any of its Subsidiaries
for Taxes except for Liens in respect of Taxes (i) not yet due, or (ii) which
are being contested in good faith and by appropriate proceedings (and for the
payment of which adequate reserves have been provided) and which are reflected
in the Arcadian SEC Documents, and neither Arcadian nor any of its Subsidiaries
has received any notice of such Liens for Taxes.
 
     (g) Except as set forth on Schedule 5.14, there is no claim, audit, action,
suit, proceeding or investigation now pending or threatened against or with
respect to Arcadian or any of its Subsidiaries in respect of any Taxes, except
for any such matters as would not, individually or in the aggregate, have a
Material Adverse Effect on Arcadian.
 
     (h) Neither Arcadian nor any of its Subsidiaries has any contractual
obligations under any tax sharing or similar agreement or arrangement or tax
indemnity agreement with any individual or entity which is not a member, as of
the date hereof, of the affiliated group of corporations (within the meaning of
Section 1504 of the Code) filing a consolidated federal income Tax Return of
which Arcadian is the common parent. Neither Arcadian nor any of its
Subsidiaries is or has been a member of an affiliated group (within the meaning

during any part of any consolidated Tax Return year within any part of such year
any corporation other than Arcadian and its Subsidiaries also was a member of
such affiliated group. Neither Arcadian nor any of its Subsidiaries has any
liability for the taxes of any person (other than Arcadian or any of its
Subsidiaries) under Treasury Regulation Section 1.1502-6 (or any similar

contract or otherwise.
 
     (i) There are no requests for rulings, determinations or information or

its Subsidiaries, no such requests or subpoenas are threatened or contemplated
by any Taxing Authority.
 
     (j) Neither Arcadian or any of its Subsidiaries owns any interest in real
property in the State of New York or in any other jurisdiction in which a Tax is
imposed on the transfer of a controlling interest in an entity that owns any
interest in real property.
 
     (k) Except as set forth on Schedule 5.14, (i) neither Arcadian nor any of
its Subsidiaries has income reportable for a period ending after the Effective
Time but attributable to a transaction (e.g., an installment sale) occurring in
or a change in accounting method made for a period ending on or prior to the
Effective Time which resulted in a deferred reporting of income from such
transaction or from such change in accounting method (other than a deferred
intercompany transaction), or deferred gain or loss arising out of any deferred
company transaction; (ii) neither Arcadian nor any of its Subsidiaries has filed
a consent under Section 341 of the Code; (iii) neither Arcadian nor any of its
Subsidiaries has entered into any compensatory contract, agreement or other
arrangement (whether formally or informally) with respect to the performance of
services which contain terms that would cause any payments thereunder made after
the Effective Time to result in a nondeductible expense to Arcadian or any of

user or related person to any principal user (within the meaning of Section
144(a) of Code) of any property which is currently financed or improved with the
proceeds of any industrial revenue bonds; (v) neither Arcadian nor any of its
Subsidiaries is a party to any safe harbor lease within the meaning of Section
168(f) of the Code, as in effect prior to its amendment by the Tax Equity and
Fiscal Responsibility Act of 1982; and (vi) neither Arcadian nor any of its
Subsidiaries has participated in or cooperated with any international boycott
within the meaning of Section 999 of the Code.
 
     (l) Neither Arcadian nor any of its Subsidiaries is a United States real
property holding corporation within the meaning of Section 897(c)(2) of the Code
during the applicable period specified in Section 897(c)(1)(A)(ii) of the Code.
 
     (m) In this Section 5.14, (i) "Tax" or "Taxes" shall mean any and all
taxes, fees, levies, duties, assessments and any other charges of any kind

affect Arcadian or its Subsidiaries; (ii) "Tax Return" shall mean all returns,

     SECTION 5.15. Fairness Opinion. Arcadian has received the opinion of CS
First Boston to the effect that, as of the date hereof, the consideration to be
received by the holders of Arcadian Common Stock in the Merger is fair to such
holders from a financial point of view.
 
     SECTION 5.16. Takeover Statutes. Assuming that none of PCS and its
Affiliates is an "Interested Stockholder" as such term is defined in Section 203

applicable to the Merger or the other transactions contemplated hereby.
 
     SECTION 5.17. Merger-Related Tax Matters.
 
     (a) Neither Arcadian nor any of its affiliates has taken or agreed to take
any action that would prevent the Merger from constituting a reorganization
qualifying under the provisions of Section 368(a) of the Code.

Effective Date to the effect that (i) Mr. Cain has no current intention to sell,
exchange, or otherwise dispose of, or reduce his risk of loss with respect to,
any PCS Common Stock received by him pursuant to the Merger, and (ii) Mr. Cain
agrees not to sell, exchange, or otherwise dispose of, or reduce his risk of
loss with respect to, 50% of the PCS Common Stock received by him in the Merger
for a period of two years after the Effective Date, and to Arcadian's knowledge,
there is no plan or intention by any stockholder of Arcadian who owns five (5)
percent or more of the Arcadian Common Stock, or the Arcadian Preferred Stock,
and to Arcadian's knowledge there is no plan or intention on the part of the
remaining holders of the Arcadian Common Stock, or of the Arcadian Preferred
Stock, to sell, exchange or otherwise dispose of a number of shares of PCS
Common Stock to be received in the Merger that would reduce the Arcadian
stockholders' ownership of the PCS Common Stock to a number of shares having a
value, as of the Effective Date, of less than fifty (50) percent of the value of
all of the Arcadian Common Stock and Arcadian Preferred Stock outstanding
immediately prior to the Effective Time. In making this determination, Arcadian
Common Stock and Arcadian Preferred Stock redeemed within one year prior to the
Merger and Arcadian Common Stock and Arcadian Preferred Stock exchanged for cash
or other property, surrendered by dissenters for cash or exchanged for cash in
lieu of fractional shares of PCS Common Stock will be included.
 
     (c) The Surviving Corporation will acquire at least ninety (90) percent of
the fair market value of the net assets and at least seventy (70) percent of the
fair market of the gross assets held by Arcadian immediately prior to the
Merger. For purposes of this representation, amounts used by Arcadian to pay
Merger expenses
 
                                       19
<PAGE>   25

by Arcadian within one year preceding the Merger, will be included as assets of
Arcadian held immediately prior to the Merger.
 
     (d) The liabilities of Arcadian to be assumed by the Surviving Corporation
and the liabilities to which the assets of Arcadian are subject were incurred by
Arcadian in the ordinary course of its business.
 
     (e) Arcadian and the holders of Arcadian Common Stock and Arcadian
Preferred Stock will pay their own respective expenses, if any, incurred in
connection with the Merger.
 
     (f) There is no indebtedness existing between PCS and Arcadian or between
Merger Sub and Arcadian that was issued, acquired, or will be settled at a
discount.
 
     (g) Neither Arcadian nor any of its Subsidiaries is an investment company
as defined in Section 368(a)(2)(F)(iii) or (iv) of the Code.
 
     (h) Arcadian is not under the jurisdiction of a court in a U.S.C. Title 11
or similar case within the meaning of Section 368(a)(3)(A) of the Code.
 
     (i) The fair market value of the assets of Arcadian to be acquired by the
Surviving Corporation will equal or exceed the sum of the liabilities to be
assumed by the Surviving Corporation in the Merger, plus the amount of the
liabilities to which Arcadian's assets are subject.
 
     SECTION 5.18. Brokers or Finders. Arcadian has not engaged any agent,
broker, investment banker, financial advisor or other firm or person who is or
will be entitled to any brokers' or finders' fee in connection with the
transactions contemplated by this Agreement other than CS First Boston.

commitments of each member of the Board of Directors to vote all shares of
Arcadian Common Stock and Arcadian Preferred Stock over which such member
exercises voting control in favor of the adoption of this Agreement and approval

and documents as PCS may reasonably request for the purpose of reviewing such
list. Arcadian shall use its reasonable best efforts to cause each person who is
identified as an "affiliate" in the list furnished pursuant to this Section 6.04
to execute a written agreement on or prior to the Effective Time, in a form
satisfactory to PCS (an "Affiliate Agreement"), that such person will not offer
or sell or otherwise dispose of any of the shares of PCS Common Stock issued to

Time.
 
     SECTION 6.06. Filings; Other Action. Subject to the terms and conditions
herein provided, PCS and Arcadian shall (a) promptly make their respective
filings and thereafter make any other required submissions under the HSR Act,
(b) use reasonable best efforts to cooperate with one another in (i) determining
whether any filings are required to be made with, or consents, permits,

the United States or Canadian federal government or any agencies, departments or
instrumentalities thereof or governmental, provincial or regulatory authorities
of the several states, provinces and foreign jurisdictions in connection with
the execution and delivery of this Agreement and the consummation of the
transactions contemplated hereby and thereby and (ii) timely making all such
filings and timely seeking all such consents, permits, authorizations or
approvals, and (c) use reasonable best efforts to take, or cause to be taken,
all other actions and do, or cause to be done, all other things necessary,

state antitrust enforcement authorities or competition authorities of any other
nation or other jurisdiction or any other Person may assert under relevant
antitrust or competition laws with respect to the transactions contemplated
hereby.
 
     SECTION 6.07. Further Assurances. In case at any time after the Effective
Time any further action is necessary or desirable to carry out the purposes of
this Agreement, the proper officers or directors of PCS and the Surviving
Corporation shall take all such necessary action.

transactions contemplated hereby may be consummated as promptly as practicable
on the terms contemplated hereby and otherwise act to eliminate or minimize the
effects of such statute or regulation on the transactions contemplated hereby.
 
     SECTION 6.09. No Solicitation. Unless and until this Agreement shall have
been terminated by either party pursuant to Section 8.01, neither PCS nor
Arcadian nor any of their respective Subsidiaries, officers, directors or agents
shall, directly or indirectly, take any action to solicit, initiate or encourage
any proposal or offer with respect to a merger, acquisition, consolidation or
similar transaction involving, or any purchase of all or any significant portion
of the assets or any equity securities of, it or any of its Subsidiaries (any
such proposal or offer being hereinafter referred to as a "Third Party
Acquisition Proposal"); provided, however, that the foregoing limitation shall
not apply if, in the good faith judgment of Arcadian's Board of Directors after
consultation with legal counsel and financial advisors, such Board's fiduciary
duties require such Board or
 
                                       23
<PAGE>   29
 
Arcadian to take any such action. PCS and Arcadian each will promptly notify the
other of its receipt of any Third Party Acquisition Proposal, and will provide
the other with two business days' advance notice of any agreement to be entered
into with any Person making a Third Party Acquisition Proposal.
 
     SECTION 6.10. Public Announcements. PCS and Arcadian will consult with each
other before issuing any press release relating to this Agreement or the
transactions contemplated herein and shall not issue any such press release
prior to such consultation except as may be required by law or by obligations
pursuant to any listing agreement with any national securities exchange.
 
     SECTION 6.11. Indemnification and Insurance. For a period of six years
after the Effective Time, PCS shall cause to be maintained in effect (a) the
current provisions regarding indemnification of officers and directors contained
in the Restated Certificate of Incorporation and Amended and Restated Bylaws of
Arcadian, and (b) if available, the current policies of directors' and officers'
liability insurance and fiduciary liability insurance maintained by Arcadian
(provided that PCS may substitute therefor policies of at least the same
coverage and amounts containing terms and conditions which are, in the
aggregate, no less advantageous to the insured) with respect to claims arising
from acts or omissions which occurred on or before the Effective Time; provided,
that PCS shall not be obligated to pay premiums in excess of 200% of the amount
per annum that Arcadian paid in the aggregate in its last fiscal year, it being
understood that PCS shall nevertheless be obligated to provide such coverage as
may be obtained for such amount. PCS shall assume all obligations of Arcadian
and any of its Subsidiaries under any indemnification or similar agreements with
any employee, officer or director of Arcadian in effect immediately prior to the
Effective Time, in each case without releasing the indemnitor under such
agreements.
 
     SECTION 6.12. Accountants' Letters. PCS and Arcadian will each use
reasonable best efforts to cause to be delivered to each other letters from
their respective independent accountants, dated a date within two business days
before the effective date of the Registration Statement, in form and substance
reasonably satisfactory to the recipient and customary in scope and substance
for "comfort" or similar agreed upon procedures letters delivered by independent
accountants in connection with registration statements on Form S-4 under the
Securities Act.
 
     SECTION 6.13. Arcadian Preferred Stock. In connection with the Merger,
Arcadian (i) will elect the "Common Conversion Option" (as defined in the
Certificate of Designation), and the holders of shares of Arcadian Preferred
Stock immediately prior to the conversion thereof pursuant to the exercise of
such Common Conversion Option shall be entitled to the benefits thereof, all as
set forth in the Certificate of Designation.
 
     SECTION 6.14. Additional Reports. PCS and Arcadian shall each furnish to
the other copies of any reports of the type referred to in Sections 4.06 and
5.06 which it files with the SEC on or after the date hereof, and PCS or
Arcadian, as the case may be, represents and warrants that as of the respective
dates thereof, such reports will not contain any untrue statement of a material
fact or omit to state a material fact required to be stated therein or necessary
to make the statement therein, in light of the circumstances under which they
were made, not misleading. Any unaudited consolidated interim financial
statements included in such reports (including any related notes and schedules)
will fairly present the financial position of PCS or Arcadian, as the case may
be, and its consolidated Subsidiaries, as of the dates thereof and the results
of operations and changes in financial position or other information included
therein for the periods or as of the date then ended (subject, where
appropriate, to normal year-end adjustments), in each case in accordance with
past practice and GAAP or Canadian GAAP, as the case may be, consistently
applied during the periods involved (except as otherwise disclosed in the notes
thereto).
 
     SECTION 6.15. Arcadian Warrants. (a) In connection with the Merger,
Arcadian will (i) take such action as may be reasonably necessary to cause or
require each outstanding AAC Warrant to be exercised for shares of Arcadian
Common Stock prior to the Effective Time pursuant to the third sentence of
Section IV(A)(3) of the AAC Warrant Agreement, and at the Effective Time the
Arcadian Common Stock issued upon such exercise shall be converted into the
Merger Consideration in the Merger pursuant to Section 1.01(b)(i) of this
Agreement; and (ii) take all action necessary under the Series B Warrant
Agreement so that at the Effective Time, each outstanding Series B Warrant
shall, pursuant to Sections 2.05
 
                                       24
<PAGE>   30
 
and 3.02 of the Series B Warrant Agreement, be deemed to constitute a warrant
having such terms and conditions as may be required by the Series B Warrant
Agreement.
 
     (b) As used in this Agreement:
 
          (i) "AAC Warrant Agreement" means the Warrant Issuance Agreement dated
     as of May 31, 1989, between Arcadian (formerly named Fertilizer Industries,
     Inc.) and AAC Holdings, Inc., on behalf of the holders of the AAC Warrants;
 
          (ii) "AAC Warrant" means a warrant issued pursuant to the AAC Warrant
     Agreement;
 
          (iii) "Series B Warrant Agreement" means the Warrant Agreement dated
     as of December 22, 1989, between Arcadian and Chemical Bank, as Warrant
     Agent, as amended; and
 
          (iv) "Series B Warrant" means a warrant issued pursuant to the Series
     B Warrant Agreement.
 
     SECTION 6.16. No Purchase. Except for the transactions contemplated by this
Agreement, without the prior written consent of Arcadian, in the case of PCS, or
PCS, in the case of Arcadian, from the date hereof until the Effective Time,
neither PCS nor Arcadian shall (a) acquire, offer to acquire or agree to
acquire, directly or indirectly, by purchase or otherwise, any securities or
direct or indirect rights to acquire any securities of Arcadian, in the case of
PCS, or PCS in the case of Arcadian, or any of their respective Subsidiaries, or
of any successor to, or any assets of, Arcadian, in the case of PCS, or PCS, in
the case of Arcadian, or any of their respective Subsidiaries or divisions; or
(b) make, or in any way participate in, directly or indirectly, any
"solicitation" of "proxies" (as such terms are used in the rules of the SEC) to
vote, or seek to advise or influence any Person with respect to the voting of,
any voting securities of Arcadian, in the case of PCS, or PCS, in the case of
Arcadian, or of any of their respective Subsidiaries, and PCS and Arcadian shall
each use reasonable efforts to cause their respective affiliates not to do any
of the foregoing. Arcadian shall promptly advise PCS, and PCS shall promptly
advise Arcadian, of any inquiry or proposal made to it with respect to any of
the foregoing. Notwithstanding clauses (a) and (b) of this Section 6.16, PCS and
Arcadian may make any proposals or communications to each other.
 
     SECTION 6.17. Employee Benefit Plans. (a) It is understood and agreed that
the Merger shall constitute a "Change of Control" or "Change in Control" within
the meaning assigned to such terms, as applicable, under certain employee
incentive plans, option plans, severance programs and employment contracts of
Arcadian and any agreements relating thereto.
 
     (b) At the Effective Time or as soon thereafter as administratively
practicable, PCS shall cause those employees of Arcadian and its Subsidiaries
who are then employed by the Surviving Corporation or any of its Subsidiaries in
positions that are not covered by a collective bargaining agreement (the
"Current Employees") either (i) to be covered by the benefit plans and programs
of PCS and its Subsidiaries with substantially equivalent benefits in respect of
future service that accrue in respect of future services to the employees of PCS
and its Subsidiaries who are employed in comparable positions, or (ii) to be
covered by the benefit plans and programs of Arcadian and its Subsidiaries as in
effect immediately prior to the Effective Time; provided, however, that nothing
herein shall relieve the Surviving Corporation of its obligations under the
Severance Program or under any Employment Agreement or similar contractual
obligation. Current Employees shall be credited for their service with Arcadian
and its Subsidiaries and their predecessors for purposes of participation,
eligibility and vesting under the benefit plans and programs provided by PCS,
and benefit accrual purposes for vacation, severance, pension and retirement
benefits only, and PCS shall cause its group health plan that will provide
coverage to Current Employees to waive any limitations regarding pre-existing
conditions of Current Employees and their eligible dependents (except to the
extent that such limitations would have applied to any such individual under the
group health plan of Arcadian and its Subsidiaries). Upon request of PCS,
Arcadian and its Subsidiaries shall provide PCS's employees with reasonable
access prior to the Effective Time to the Current Employees for purposes of
enrolling such employees and their eligible dependents in the benefit plans and
programs of PCS and its Subsidiaries that are to be provided to such
individuals.
 
                                       25
<PAGE>   31
 
     (c) PCS agrees that each officer and other employee of Arcadian or any of
its Subsidiaries who is a party to a written employment agreement with Arcadian
or any of its Subsidiaries, and who remains in the employment of PCS, Surviving
Corporation or any of its other Subsidiaries after the expiration of the term of
such agreement, shall be entitled to the benefits of an employment agreement
with PCS in form and substance substantially similar to the employment
agreement, then in place between PCS and other employees of PCS holding
comparable positions.
 
     SECTION 6.18. Conduct of PCS's Business. Prior to the Effective Time or the
Termination Date, and except as may be permitted pursuant to this Agreement,
PCS:
 
          (a) shall, and shall cause its Subsidiaries to, conduct its and their
     operations in the ordinary and usual course of business in substantially
     the same manner as heretofore conducted;
 
          (b) except as otherwise contemplated herein, shall not effect any
     stock split or otherwise change its capitalization as it existed on June
     30, 1996 (provided, however, that the exercise of employee stock options
     and issuance of shares of PCS Common Stock pursuant to the PCS DRIP shall
     not be considered to be a change in the capitalization of PCS); and
 
          (c) shall not, and shall not permit any of its Subsidiaries to, amend
     any term of any of its or their outstanding securities.

     injunction shall have been enacted, entered, promulgated or enforced by any
     court or governmental authority that prohibits the consummation of the
     Merger substantially on the terms contemplated hereby. If any such order,
     decree or injunction shall have been issued, each party shall use its
     reasonable best efforts to remove such order, decree or injunction.
 
          (c) The Registration Statement shall have become effective in
     accordance with the provisions of the Securities Act and shall be effective

          (e) Any applicable waiting period under the HSR Act shall have expired
     or been terminated and any other approvals sets forth in Sections 4.03 and
     5.03 shall have been obtained, except where the failure to obtain such
     other approvals (other than the expiration or termination of the waiting
     period under the HSR Act) would not have a Material Adverse Effect on PCS
     or Arcadian, as the case may be.
 
          (f) Arcadian shall have received an opinion of its tax counsel,
     Bracewell & Patterson, L.L.P., in form and substance reasonably
     satisfactory to it, and dated within five days prior to the date of the
     Proxy Statement to the effect that neither it nor any of its stockholders
     shall recognize gain or loss for United States federal income tax purposes

     shares) which opinion shall have been reconfirmed as of the date on which
     the Effective Time occurs (the "Effective Date").

<PAGE>   32
 
          (g) PCS shall have received an opinion of its tax counsel, Goodman,
     Phillips & Vineberg, in form and substance reasonably satisfactory to it,

     section 368(a)(2)(D), which opinion shall have been reconfirmed as of the

be true and correct in all respects (but without regard to any materiality

Effective Time with the same effect as though made as of such time except for

all material respects all obligations and complied in all material respects with
all covenants required by this Agreement to be performed or complied with by it
prior to the Effective Time.
 
     SECTION 7.03. Additional Conditions of Arcadian. The obligation of Arcadian

Adverse Effect on PCS, and (b) PCS and Merger Sub shall have performed in all
material respects all obligations and complied in all material respects with all
covenants required by this Agreement to be performed or complied with by it
prior to the Effective Time.

          (b) by PCS or Arcadian if the Effective Time shall not have occurred
     on or before February 28, 1997; provided, that the party seeking to
     terminate this Agreement pursuant to this Section 8.01(b) shall not have
     breached in any material respect its obligations under this Agreement in
     any manner that shall have proximately contributed to the failure to
     consummate the Merger on or before such date;
 
          (c) by PCS or Arcadian if a United States federal or state court of
     competent jurisdiction or United States governmental, regulatory or

     ruling or taken any other action permanently restraining, enjoining or
     otherwise prohibiting the transactions substantially on the terms
     contemplated by this Agreement and such order, decree, ruling or other
     action shall have become final and non-appealable; provided, that the party
     seeking to terminate this Agreement pursuant to this Section 8.01(c) shall
     have used its reasonable best efforts to remove such restraint, injunction
     or prohibition;
 
          (d) by PCS if (i) the approvals of the stockholders of Arcadian
     contemplated by this Agreement shall not have been obtained by reason of
     the failure to obtain the required vote at a duly held meeting of
     stockholders or any adjournment thereof or (ii) prior to the Special
     Meeting, the Board of Directors of Arcadian shall have withdrawn or
     modified, or resolved to withdraw or modify its approval or recommendation

     investigation of the business and operations of the other party shall have
     revealed the existence of
 
                                       27
<PAGE>   33
 
     a fact or condition relating to such other party or its Subsidiaries that

     Documents, as the case may be, and (ii) in the terminating party's
     reasonable, good-faith judgment has had or may reasonably be expected to
     have a Material Adverse Effect on the other party in excess of any
     provision made with respect thereto in the other party's December 31, 1995
     or June 30, 1996 financial statements included in the PCS Disclosure
     Documents or Arcadian SEC Documents, as the case may be. Any such notice

     outline in reasonable detail the basis for such termination;
 
          (f) by Arcadian, if its Board of Directors shall have determined, in
     its good faith judgment after consultation with legal counsel and financial
     advisors, that such Board's fiduciary duties require termination of this
     Agreement;
 
          (g) by Arcadian, if the approval of the stockholders of Arcadian
     contemplated by this Agreement shall not have been obtained by reason of
     the failure to obtain the required vote at a duly held meeting of such
     stockholders or any adjournment thereof;

          (i) by PCS, by a written notice delivered to Arcadian on or before

     interests in Arcadian Trinidad Corporation, Arcadian Fertilizer
     Corporation, AA Sulfuric Corporation, August Service Company Inc., Arcadian
     LCD Corporation and Arcadian FMF, L.L.C. and any other interests in
     corporations or limited liability companies held by Arcadian Partners, L.P.
     or Arcadian Fertilizer L.P. to be held through a chain of corporations with
     no partnership in the chain of ownership exceeds $25,000,000 in addition to

     all prepayment premiums payable thereon).
 
     In the event of termination of this Agreement pursuant to this Section
8.01, this Agreement shall terminate, and there shall be no other liability
under this Agreement on the part of either party to the other party except that

Agreement shall survive the termination hereof and (ii) no such termination
shall relieve either party of any liability or damages arising out of a breach
of this Agreement by that party.

     acts of the other;
 
          (b) waive any inaccuracies in the representations and warranties of
     the other party contained herein or in any document delivered pursuant
     hereto; or
 
          (c) waive compliance with any of the agreements or conditions of the
     other party contained herein.
 
     Notwithstanding the foregoing, no failure or delay by PCS or Arcadian in
exercising any right hereunder shall operate as a waiver thereof nor shall any
single or partial exercise thereof preclude any other or further exercise
thereof or the exercise of any other right hereunder. Any agreement on the part
of a party hereto to any such extension or waiver shall be valid only if set
forth in an instrument in writing signed on behalf of such party.

              Amendment No. 2 dated as of August 26, 1996 to Lease Agreement
("Amendment No. 2"), dated as of June 29, 1995, between Trinidad Ammonia
Company, Limited Partnership, a Delaware limited partnership ("Lessor"), and
Arcadian Fertilizer, L.P., a Delaware limited partnership ("Lessee"), amending
the Lease Agreement referred to below.

              WHEREAS,  Lessor and Lessee have heretofore entered into an Lease
Agreement, dated as of June 29, 1995, as amended by Amendment No. 1, dated as
of August 20, 1996 (collectively, the "Lease Agreement"); and

              WHEREAS, Lessor and Lessee wish to further amend the Lease
Agreement as hereinafter provided;

              NOW, THEREFORE, Lessor and Lessee hereby agree that the Lease
Agreement is amended as follows:

              1.     Section 1 of the Lease Agreement is hereby amended by
adding the following definition thereto:

                     "'Appraisal Procedure' means the following procedure
              whereby an independent appraiser shall be appointed by the Lessor
              and the Lessee, with the consent of the Assignee, to determine
              the amount, if any, by which the sales price of the Ammonia
              Project has been reduced as the direct result of wear and tear in
              excess of the wear and tear that would have occurred if the
              Lessee's obligations contained in the second sentence of
              paragraph (b) of Section 9 of this Lease had been satisfied, if
              such determination is required under Section 19 of this Lease.
              If no such appraiser is appointed by the Lessor and the Lessee
              within thirty (30) days after the written request of either the
              Lessor or the Lessee that an appraiser be appointed, the Lessor
              and the Lessee shall each appoint an independent appraiser within
              thirty (30) days thereafter, and the two appraisers so appointed
              shall appoint a third independent appraiser.  Each appraiser
              appointed pursuant to the foregoing procedure shall, within
              thirty (30) days after appointment of the last appraiser,
              independently determine the amount, if any, by which the sales
              price of the Ammonia Project has been reduced as the direct
              result of wear and tear in excess of the wear and tear that would
              have occurred if the Lessee's obligations contained in the second
              sentence of paragraph (b) of Section 9 of this Lease had been
              satisfied.  If the Lessor or the Lessee shall fail to appoint an
              independent appraiser within the above-mentioned thirty (30) day
              period, the appraiser appointed by the other party shall
              determine such amount.  If a single appraiser is appointed, such
              appraiser's determination shall be final.  If three appraisers
              are appointed, the amounts determined by the three appraisers
              shall be averaged, the amount which differs the most from such
              average shall be excluded, the remaining two amounts shall then
              be averaged and such average shall be final.  The expenses off
              all appraisers shall be paid by the Lessee. Each appraiser
              appointed pursuant to this "Appraisal Procedure" shall be an
              independent engineering firm of recognized standing and shall
              have experience in the construction, maintenance and operation of
              ammonia production plants."

              2.     Paragraph (d) of Section 10 of the Lease Agreement is
hereby amended to read in its entirety as follows:

              for the Lessor, procure or cause to be procured and maintain or
              cause to be maintained in respect of Property or Equipment not
              located in the United States, for the Lessor, with the
              Multilateral Investment Guaranty Agency or such other insurance
              company as shall be reasonably acceptable to the Lessor, a policy
              of political risk insurance covering (i) transfer restrictions,
              (ii) expropriation and (iii) war and civil disturbance; provided,
              that the amount of such political risk insurance in respect of
              the Ammonia Project shall equal or exceed the Acquisition Cost of
              the Ammonia Project less the sum of (A) the face amount of the

adding the following paragraph (j) to such section, to read in its entirety as
follows:

                     "(j) If (i) an Event of Default arising solely as a result
              of the Lessee's failure to comply with its obligations contained
              in the second sentence of paragraph (b) of Section 9 of this
              Lease shall have occurred and be continuing, (ii) the Lessor
              shall terminate this Lease or the Lessee's right to the use and
              possession of the Ammonia Project, and (iii) the Lessor shall
              sell the Ammonia Project, then if the proceeds of such sale are
              less than 15% of the Acquisition Cost of the Ammonia Project, the
              Lessee shall pay to the Lessor the amount by which the sales
              price of the Ammonia Project has been reduced as the direct
              result of wear and tear in excess of the wear and tear that would
              have occurred if the Lessee's obligations contained in the second
              sentence of paragraph (b) of Section 9 of this Lease had been
              satisfied (the amount by which the sales price of the Ammonia
              Project has been reduced as the direct result of wear and tear in
              excess of the wear and tear that would have occurred if the
              Lessee's obligations contained in the second sentence of
              paragraph (b) of Section 9 of this Lease had been satisfied, to
              be such amount, if any, as the Lessor and the Lessee agree, or if
              no agreement is reached, the amount, if any, determined pursuant
              to the Appraisal Procedure); provided that, in no event shall the
              Lessee be required to pay an amount that, when combined with the
              proceeds received by the Lessor from the purchaser of the Ammonia
              Project, exceeds 15% of the Acquisition Cost of the Ammonia
              Project."

              4.   This Amendment No. 2 may be executed in several
counterparts, each of which when executed and delivered shall be deemed an
original and all of which counterparts, taken together, shall constitute but
one and the same Amendment No. 2.

FF&E Specifications relating thereto; provided, that no such amendment,
modification or supplement shall increase the Unit Budget to an amount in excess
of the maximum cost for acquisition set forth in the first sentence of this
subsection 2.2 or result in the Unit not being completed on or prior to its Unit
Completion Date in all material respects in accordance with the Unit Plans.
Agent shall promptly deliver to Owner and any Assignee any such amended,

within five (5) Business Days of receipt of the Certificate of Substantial
Completion, a fully completed AFL Unit Leasing Record executed by Agent and the
other documents required in Section 6 hereof, shall execute and deliver to Agent
such AFL Unit Leasing Record. Except as provided below, the Final Advance shall
be made by Owner on the date of execution by Owner of the AFL Unit Leasing
Record. If Substantial Completion of the Unit will not be effected on or before
the Designated Effective Date with respect to the Unit, Agent shall prepare and
execute an AFL Unit Leasing Record with respect to the Unit and deliver it to
Owner, at least five (5) days prior to the Designated Effective Date. Owner
shall execute and deliver to Agent the AFL Unit Leasing Record by the Designated
Effective Date, and Owner's obligation to make further advances, other than a
Completion Advance, with respect to the Unit under this Agreement shall
terminate on the Designated Effective Date. Agent may request and receive on the
Designated Effective Date an advance pursuant to Section 5, provided all
conditions to such advance under Section 5 are met. Such AFL Unit Leasing Record
shall have an Effective Date as of the date of the Designated Effective Date.
Execution and delivery by Agent of the AFL Unit Leasing Record shall constitute
(i) acknowledgment and representation by Agent that each Unit included therein
(taking into account its then current state of construction) is in good
condition, conforms in all material respects to the Unit Plans and has been
accepted for lease under the Lease by Agent as of the Effective Date of the AFL
Unit Leasing Record, (ii) acknowledgment by Agent that each such Unit is subject
to all of the covenants, terms and conditions of the Lease, and (iii)
certification by Agent that the representations and warranties contained in
Section 2 of the Lease are true and correct in all material respects on and as
of the Effective Date of the AFL Unit Leasing Record as though made on and as of
such date and that there exists on such date no (1) Event of Default or, with
respect to such Unit, Event of Unit Termination or Casualty Event under this
Agreement or Event of Default (as defined in the Lease) or (2) Potential Default
or, with respect to such Unit, Potential Event of Unit Termination under this
Agreement or Potential Default (as defined in the Lease). Upon execution and
delivery of an AFL Unit Leasing Record by Owner, such Unit shall become a Parcel
of Property (as defined in the Lease).

                  (b) Notwithstanding the foregoing, but subject to the terms of
subsection 3.1 hereof, Agent may, by delivering to Owner a Certificate of
Increased Cost (in the form of Exhibit F hereto), at any time up to six (6)
months after the date on which the Final Advance has been made with respect to a
Unit or, if no Final Advance was made prior to the Designated Effective Date, at
any time prior to the Unit Completion Date, request a Completion Advance in
order to pay to Agent construction costs that were not the subject of any
previous advance. Owner, within five (5) Business Days of receipt and upon
Owner's approval of a request for the Completion Advance and the Certificate of
Increased Cost, shall execute and deliver to Agent a revised AFL Unit Leasing
Record for such Unit reflecting such increased cost, and Agent, within five (5)
Business Days of receipt of such revised AFL Unit Leasing Record, shall sign the
revised AFL Unit Leasing Record and return it to Owner. If no Final Advance was
made on or prior to the Designated Effective Date, at the time Agent returns the
executed revised AFL Unit Leasing Record (which shall occur on a date on or
prior to the Unit Completion Date for such Unit), it shall also deliver the
documents required by Section 6 hereof as if a Final Advance was being made at
such time. The Completion Advance shall be made by

Owner upon receipt of the revised AFL Unit Leasing Record signed by Agent and,
if applicable, the documentation required by the previous sentence. Execution
and delivery by Agent of the revised AFL Unit Leasing Record shall constitute
(i) acknowledgment and representation by Agent that each Unit included therein
is in good condition, conforms in all material respects to the Unit Plans and
has been accepted for lease under the Lease by Agent as of the Effective Date of
the AFL Unit Leasing Record, (ii) acknowledgment by Agent that each such Unit is
subject to all of the covenants, terms and conditions of the Lease, and (iii)
certification by Agent that the representations and warranties contained in
Section 2 of the Lease are true and correct in all material respects on and as
of the Effective Date of the revised AFL Unit Leasing Record as though made on
and as of such date and that there exists on such date no (1) Event of Default
or, with respect to such Unit, Event of Unit Termination or Casualty Event under
this Agreement or Event of Default (as defined in the Lease) or (2) Potential
Default or, with respect to such Unit, Potential Event of Unit Termination under
this Agreement or Potential Default (as defined in the Lease).

                  2.4 Powers of Agent. Agent shall have the right to act for and
on behalf of Owner with full and complete authority to appear before each
applicable Governmental Authority to resolve issues related to the platting,
zoning and use of the Unit Premises, to obtain all Permits, to grant and obtain
easements for the benefit of any Unit Premises or which are reasonably deemed
necessary by Agent for the installation or operation of the Ammonia Project
(provided that no such action shall contravene any provision of any Ground
Lease) in all material respects in accordance with the Unit Plans, appoint,
employ and deal with the architects, engineers, consultants and contractors,
purchase and arrange for delivery of all materials, supplies, furniture,
fixtures, and equipment, and to approve all related vouchers, invoices and
statements. Notwithstanding the foregoing, Owner agrees to execute directly any
and all such documents which Governmental Authorities do not permit to be
exercised pursuant to a power of attorney or as Agent may reasonably deem to be
necessary to effect the purposes of this Agreement. No payment shall be made for
any property or services of such architects, engineers, consultants, or
contractors relating to the acquisition, construction and equipping of any Unit
without the prior approval of Agent, and each amount so approved and paid shall
be in accordance with the Unit Budget, and shall be part of the Unit Acquisition
Cost of such Unit. If Agent has unreasonably delayed or withheld giving the
approvals required to make such payments, Owner may make payments to any
architects, engineers, consultants, contractors, vendors or suppliers which are
properly due and payable in accordance with the contracts with said parties, and
any such payment so made shall be and become a part of the Unit Acquisition Cost
of the Unit; provided, however, that Owner shall not make any such payment if it
is subject to a Permitted Contest.

                  SECTION 3. ADVANCES

                  3.1 Agreement to Make Advances. Subject to the conditions and

                  SECTION 8. REPRESENTATIONS AND WARRANTIES OF AGENT

                  Agent represents and warrants to Owner now and on the date of
each advance that:

                  8.1 Partnership Matters. Agent (i) has been duly organized and
is validly existing as a limited partnership in good standing under the laws of
the State of Delaware, (ii) has full power, authority and legal right to own and
operate its properties and to conduct its business as presently conducted and to
execute, deliver and perform its obligations under this Agreement and any other
Operative Document to which it is or is to be a party and to consummate the
transactions contemplated hereby and by the other Operative Documents and (iii)
to the best of its knowledge after due inquiry, is duly qualified to do business
as a foreign limited partnership in good standing in each jurisdiction in which
its ownership or leasing of properties or the conduct of its business or the
consummation of the transactions contemplated hereby and by the other Operative
Documents requires such qualification, except where the failure to so qualify
would not materially impair the ability of Agent to perform its obligations
hereunder or under the other Operative Documents. The sole general partner of
Agent is Arcadian Corporation.

                  8.2 Power and Authority. The consummation by Agent of the
transactions contemplated by the Operative Documents and the execution, delivery
of and performance and observance by Agent of its obligations under this
Agreement and the other Operative Documents to which it is or is to be a party
have been duly authorized by all necessary action on the part of the partners of
Agent. None of the execution, delivery and performance by Agent of this
Agreement or any other Operative Document to which Agent is or is to be a party
will result in any violation of any term of the certificate of limited
partnership or the partnership agreement of Agent, or require the approval or
consent of any limited partner or general partner of Agent except such as have
been obtained prior to the date hereof and will not conflict with or result in a
breach in any material respect of any terms or provisions of, or constitute a
default under, or result in the creation or imposition of any Lien (other than a
Permitted Lien) upon any property or assets of Agent under, any indenture,
mortgage or other agreement or instrument to which Agent is a party or by which
it or any of its property is bound, or any existing applicable law, rule,
regulation, license, judgment, order or decree of any Governmental Authority or
court having jurisdiction over Agent or any of its activities or properties.

                  8.3 Binding Agreement. Each of this Agreement and each other
Operative Document to which Agent is or is to be a party has been duly
authorized and has been or will be duly executed and delivered by Agent and,
assuming the due authorization, execution and delivery of this Agreement and any
other such Operative Document by the parties thereto other than Agent, this
Agreement is, and each such other Operative Document when executed and delivered
will be, the legal, valid and binding obligation of Agent, enforceable against
Agent according to their terms, subject, as to enforceability, to applicable
bankruptcy, insolvency and similar laws affecting creditors' rights generally,
and to general principles of equity (regardless of whether enforcement is sought
in a proceeding in equity or at law).

                  8.4 No Litigation. Except as described in Exhibit N hereto,
there is no action, suit, proceeding or investigation at law or in equity by or
before any court, governmental body, agency, commission or other tribunal now
pending or, to the knowledge of Agent, threatened against or affecting Agent or
any property or rights of Agent which questions the enforceability of this
Agreement or any other Operative Document or which affects any or relates to any
Unit Premises, Unit Improvements, Unit FF&E or Unit or which, if adversely
determined, would have a reasonable possibility of causing a material adverse
impact on the business of Agent in the aggregate or would materially impair the
ability of Agent to perform its obligations hereunder or under any other
Operative Document.

                  8.5 Consents, Approvals, Authorizations, Etc. There are no
consents, licenses, orders, authorizations, approvals, waivers, extensions or
variances of, or notices to or registrations or filings with (each a
"Governmental Action"), any Governmental Authority or public body or authority
in any jurisdiction which are or will be required in connection with or are
necessary to the valid execution, delivery and performance of this Agreement or
any other Operative Document or any Governmental Action (i) which is or will be
required in connection with any participation by Owner in the transactions
contemplated by, or the exercise of remedies or the enforcement of rights by
Owner under, this Agreement or any other Operative Document, any bill of sale,
deed, assignment, assumption, ownership agreement, or operating agreement
relating to any Unit Premises, Unit Improvements, Unit FF&E or Unit or (ii)
which is or will be required to be obtained by Owner, Agent, any Assignee or an
Affiliate of the foregoing, during the term of this Agreement, with respect to
any Unit Premises, Unit Improvements, Unit FF&E or Unit except the Governmental
Action of the Town and Country Planning Authority of the Republic of Trinidad
and Tobago, which Governmental Action Agent reasonably believes will be obtained

Project, and such other Governmental Actions (A) as have been duly obtained,
given or accomplished, with true copies thereof delivered to Owner, (B) as may
be required by applicable law not now in effect, (C) which, individually or in
the aggregate, if not obtained or effected, (x) will not place either Owner or
any Assignee in any danger of any monetary civil liability for which Owner or
any Assignee is not adequately indemnified (Agent's obligations under Section 12
of this Agreement shall be deemed to be adequate indemnification if no Event of
Default exists) or any other material civil liability or penalty or subject
Owner or any Assignee to any criminal liability as a result of a failure to
comply therewith, (y) will not result in a material diminution in the value of
any Unit Premises, Unit Improvements, Unit FF&E or Unit or in any material risk
of the loss, sale or forfeiture or loss of use of any thereof, and (z) will not
materially impair the ability of Agent to perform its obligations hereunder, (D)
as may be required for the construction or operation of the Ammonia Project and
have been or will be timely obtained or (E) which may be required as a result of
the business, properties or activities of Owner, any Assignee or any Affiliate
of the foregoing and which are not solely dependent on the nature of the Unit
Premises, Unit Improvements, Unit FF&E or Units or the business of Agent.

                  8.6 Compliance with Legal Requirements and Insurance
Requirements. The construction, operation, use, and physical condition of each

Improvements, Unit and item of Unit FF&E comply with all Legal Requirements and
Insurance Requirements; except any Legal Requirements, the non-compliance with
which, individually or in the aggregate, (i) will not place either Owner or any
Assignee in any danger of any monetary civil liability which Owner or any
Assignee is not adequately indemnified for (Agent's obligations under Section 12
of this Agreement shall be deemed to be adequate indemnification if no Event of
Default exists) or any other material civil liability or penalty or subject
Owner or any Assignee to any criminal liability as a result of a failure to
comply therewith and (ii) will not result in a material diminution in the value
of any Unit Premises, Unit Improvements, Unit FF&E or Unit or in any material
risk of the loss, sale or forfeiture or loss of use of any thereof.

                  8.7 No Default. Agent is not in violation of or in default
under or with respect to any Legal Requirement in any respect which could have a
materially adverse effect on the business, operations, properties or financial
or other condition of Agent, or which could materially adversely affect the

statements contained in such documents fairly present in all material respects
the financial position, results of operations and statements of cash flows of
Agent as of the dates and for the periods indicated therein and have been
prepared in accordance with generally accepted accounting principles applied on
a consistent basis.

                  8.10 Changes. Since September 30, 1995, there has been no

Lease except to the extent agreed to in writing by Owner and Assignee, and is in
full force and effect and has not been modified, amended or changed in any

                  SECTION 9. AFFIRMATIVE COVENANTS

                  Agent hereby agrees that, so long as this Agreement remains in
effect, Agent shall keep and perform fully each and all of the following
covenants:

                  9.1 Performance under Other Agreements. Agent shall duly
perform and observe in all material respects all of the covenants, agreements
and conditions on its part to be performed and observed hereunder and under each
other Operative Document to which it is or is to be a party, except to the
extent that Agent's obligation in respect of such covenant, agreement or
condition may be subject to a Permitted Contest.

                  9.2 No Encroachments. The Unit Improvements shall be
constructed entirely on the related Unit Premises and shall not encroach upon or
overhang (unless consented to by the affected property owner or permitted by the
terms of any easement, license or right-of-way agreement) any easement or
right-of-way or the land of others, and when erected shall be wholly within any
building restriction lines, however established. If Owner shall have a
reasonable basis to believe any Unit Improvements are not in compliance with
this subsection 9.2, Owner may request, and Agent shall furnish from time to
time satisfactory evidence of compliance with the foregoing covenants,
including, without limitation, a survey prepared by a surveyor or engineer. If
any discrepancies exist between the legal description set forth on the survey
described in Section 4(h) hereof and the final as-built survey described in
Section 6(f) hereof, Owner and Agent shall cooperate, at Agent's expense, in
amending the legal descriptions in all recorded documents creating or
encumbering or otherwise affecting the Unit Premises, including, without
limitation, any easements, to reflect the correct as-built description.

                  9.3 Insurance.

                  (a) Insurance with respect to each Unit Premises, the Unit
Improvements, Unit FF&E and Unit. Agent will maintain or cause to be maintained
on each Unit Premises, the Unit Improvements, Unit FF&E and Unit insurance of
the same types, in the same amounts and on the same terms and conditions as the
insurance required by paragraph (c) through (l) of Section 10 of the Lease,
except that the terms "Owner", "Agent" and "this Agreement" shall substitute for
the terms "the Lessor", "the Lessee" and "this Lease", respectively, the phrase
"Unit Premises, Unit Improvements, Unit FF&E and Unit" shall substitute for the
phrase "Parcel of Property" or "Property", references to "Equipment" or "Unit of
Equipment" shall be deemed deleted, and the phrase "Unit Acquisition Cost" shall
substitute for the phrase "Acquisition Cost"; provided, that in lieu of the
insurance required by paragraph (c)(i) of Section 10 of the Lease, Agent shall,
as Owner's agent, maintain or cause to be maintained for Owner All Risk
Builders' Risk Completed Value Non-Reporting Form Insurance, including collapse
coverage and fire insurance with extended coverage, in an amount not less than
one hundred percent (100%) of the completed insurable value of the respective
Unit Improvements and Unit FF&E; provided however, that with respect to the
Ammonia Project, Agent shall not be required to maintain or cause to be
maintained All Risk Builders' Risk Completed Value Non-Reporting Form Insurance
until such date as any Unit

Improvements or Unit FF&E relating to the Ammonia Project are located in the
Republic of Trinidad and Tobago. The term "completed insurable value" as used
herein means the actual replacement cost, including the cost of debris removal,
but excluding the cost of constructing foundation and footings. Such insurance
may provide for such deductibles and Agent may self-insure with respect to the
required coverage to the extent consistent with Agent's customary practice with
respect to similar property owned by Agent.

                  (b) Use or Operation of Unit Premises, Unit Improvements, Unit
FF&E or Unit. Agent covenants that it will not use, carry on construction with
respect to, or occupy any Unit or permit the use, construction, or occupancy of
any Unit Premises, Unit Improvements, Unit FF&E or Unit at a time when the
insurance required by paragraph (a) of this subsection is not in force with
respect to such Unit Premises, Unit Improvements, Unit FF&E or Unit.

                  (c) Construction Bonding. In order to secure the performance
by the General Contractor for the Ammonia Project of its obligations under its
Construction Agreement, Agent shall furnish to Owner and maintain the
Construction Agreement Surety in such amounts and for such durations as may be
required pursuant to such Construction Agreement.

                  9.4 Inspection. Upon at least five (5) Business Days written
notice (or upon two (2) Business Days written notice if an Event of Default
shall have occurred and be continuing), Owner or Assignee or any authorized
representatives of either of them, shall have during reasonable business hours
the right of entry and free access to each Unit Premises, the Unit Improvements,
Unit FF&E and each Unit and the right to inspect all work done, labor performed
and materials furnished in and about each Unit Premises, the Unit Improvements,
Unit FF&E and each Unit and at reasonable times the right to inspect all
contracts of Agent relating to each Unit Premises, the Unit Improvements, Unit
FF&E and each Unit, but neither Owner nor any Assignee shall have any duty to
make any such inspection; provided that Agent shall be permitted to withhold
from Owner or any Assignee any information with respect to its business or work
products not related to any Unit Premises, Unit Improvements, Unit FF&E or Unit.
Owner may recover from Agent (i) the reasonable costs and expenses associated
with any inspection of the Ammonia Project, in an amount not to exceed, when
aggregated with (A) the expenses referred to in clause (i) of paragraph (d) of
Section 8 of the Lease, and (B) the fees and expenses of Owner and any Assignee
for engineering and legal services, $650,000 in the aggregate, (ii) the
reasonable costs and expenses associated with any such inspection which are
incurred following the occurrence and during the continuation of any Event of
Default throughout the term of this Agreement and (iii) all of Owner's and any
Assignee's mortgage recordation, lien and filing fees, and all out-of-pocket
expenses of Owner's legal counsel and any Assignee's legal counsel, and all
out-of-pocket expenses of any Assignee. Notwithstanding anything to the contrary
contained in the immediately preceding sentence, Agent shall not be required to
reimburse Owner for any of the foregoing costs and expenses to the extent such
costs and expenses are capitalized by Owner in Unit Acquisition Cost.

                  9.5 Expenses. Agent shall pay, whether or not Owner is
obligated to make any Advance under Sections 3 through 7 hereof, upon demand all
obligations, costs and expenses incurred in good faith by Owner with respect to
any and all transactions contemplated herein and the preparation of any document
reasonably required hereunder and the prosecution or defense of any action or
proceeding or other litigation affecting Agent or any Unit Premises, Unit
Improvements, Unit FF&E or Unit, including (without limiting the generality of

         repurchase or repay such Indebtedness, and such default, event or
         condition shall continue for more than the period of grace, if any,
         specified therein and in the case where such Indebtedness has not been
         declared due and payable such event or condition shall not have been

         by the landlord under such Ground Lease, or if any one or more of the
         events referred to in the Site lease, the Sublease or any Ground Lease
         shall occur which would cause the Site Lease, the Sublease or such
         Ground Lease to terminate without notice or action by the landlord
         thereunder or which would entitle the landlord under the Site Lease,
         the Sublease or such Ground Lease to terminate the Site Lease, the
         Sublease or such Ground Lease and the term thereof by the giving of
         notice to Owner without opportunity to cure, as tenant thereunder, or

         Assignee.

                  (l) Partnership Interest. Arcadian Corporation shall cease to
         be the general partner of Agent without the prior written consent of

                  11.2 Owner's Rights upon an Event of Default. (a) Upon the
occurrence and continuation of any Event of Default Owner may, in addition to
exercising any other rights and remedies available to it under applicable law,

                  (ii) Take immediate possession of any Unit Premises, Unit
         Improvements, Unit FF&E and Unit and remove any equipment or property
         of Owner in the possession of Agent, wherever situated, and for such
         purpose, enter upon any Unit Premises, Unit Improvements or Unit
         without liability to Agent for so doing; provided that the taking of
         possession of any Unit Premises, Unit Improvements, Unit FF&E or Unit
         shall take place in a commercially reasonable manner;

                  (iii) Whether or not any action has been taken under (a)
         above, sell any Unit Premises, Unit Improvements, Unit FF&E or Unit
         (free of or subject to the rights of Agent or any other Person under

                  (iv) Hold, use, occupy, operate, remove, lease, sublease or
         keep idle any Unit Premises, Unit Improvements, Unit FF&E or Unit as
         Owner in its sole discretion may determine, without any duty to account
         to Agent with respect to any such action or inaction, except that Owner

         its rights under this subsection 11.2 will be applied to reduce the
         Accrued Default Obligations; and

         under applicable law and in general proceed by appropriate judicial
         proceedings, either at law or in equity, to enforce the terms hereof or
         to recover damages for the breach hereof.

                  (b) Suit or suits for the recovery of any default in the
payment of any sum due hereunder or for damages may be brought by Owner from
time to time at Owner's election, and nothing herein contained shall be deemed
to require Owner to await the date whereon this Agreement or the term hereof
would have expired by limitation had there been no such default by Agent or no
such termination or cancellation.

                  (c) The receipt of any payments under this Agreement by Owner
with knowledge of any breach of this Agreement by Agent or of any default by

Agreement, shall not be deemed to be a waiver of any provision of this
Agreement.

termination or cancellation hereof in any lawful manner shall reinstate or
continue this Agreement, or operate as a waiver of the right of Owner to recover

receive any and all amounts owing by Agent to or on behalf of Owner hereunder;
it being agreed that, after the service of notice to terminate or cancel this
Agreement, and the expiration of the time therein specified, if the default has
not been cured in the meantime, or after the commencement of suit, action or
summary proceedings or of any other remedy, or after a final order, warrant or
judgment for the

possession of any Unit Premises, Unit Improvements, Unit FF&E or Unit, Owner may
demand, receive and collect any moneys payable hereunder, without in any manner
affecting such notice, proceedings, suit, action, order, warrant or judgment;
and any and all such moneys so collected shall be deemed to be payments on
account for the use, operation and occupation of the Unit Premises, Unit
Improvements, Unit FF&E or Unit, or at the election of Owner, on account of
Agent's liability hereunder and will be applied to reduce the Accrued Default
Obligations.

                  (e) Agent hereby expressly confirms that, in any event,
including after any Event of Default, and notwithstanding any termination of
this Agreement or reentry or repossession by Owner, Agent shall be liable for,
and Owner may recover from Agent, (i) all of Owner's obligations, costs and
expenses incurred in good faith in connection with its obligations under this
Agreement and for which Owner may demand reimbursement pursuant to subsection
9.5 hereof, (ii) all amounts payable hereunder or under any other Operative
Document and (iii) all losses, damages, costs and expenses (including, without
limitation, reasonable attorneys' fees and expenses, commissions, filing fees
and sales or transfer taxes) sustained by Owner by reason of such Event of
Default and the exercise of Owner's remedies with respect thereto, including, in
the event of a sale by Owner of any Unit Premises, Unit Improvements, Unit FF&E
or Unit pursuant to this subsection 11.2, all costs and expenses associated with
such sale. The amounts payable in clauses (i) through (iii) above are
hereinafter sometimes referred to as the "Accrued Default Obligations". Accrued
Default Obligations shall not include any damages for loss of profits arising
from the prospective use, operation and occupancy by parties other than Agent of
any Unit Premises, Unit Improvements, Unit FF&E or Unit or the anticipated
receipt of income therefrom subsequent to Agent's possession of such Unit
Premises, Unit Improvements, Unit FF&E or Unit.

                  (f) After an Event of Default, Owner may sell its interest in
any Unit Premises, Unit Improvements, Unit FF&E and Unit in any commercially
reasonable manner upon any terms that Owner deems satisfactory, free of any
rights of Agent or any Person claiming through or under Agent. In the event of
any such sale, or in the event Owner elects not to sell any Unit Premises, Unit
Improvements, Unit FF&E or Unit, in addition to the Accrued Default Obligations,
Owner shall be entitled to recover from Agent, as liquidated damages, and not as
a penalty, an amount equal to 84.5% of the Unit Acquisition Cost of any Unit
Premises, Unit Improvements, Unit FF&E and Units under this Agreement. Proceeds
of any such sale received by Owner, or, in the event Owner elects not to sell,
proceeds at any time thereafter received by Owner from any sale, occupation,
operation, use or lease of any Unit Premises, Unit Improvements, Unit FF&E or
Unit (net of all reasonable costs and expenses incurred by Owner in connection
with any sale, occupation, operation, use or lease of any Unit Premises, Unit
Improvements, Unit FF&E or Unit) in excess of 15.5% of the Unit Acquisition Cost
of such Unit Premises, Unit Improvements, Unit FF&E or Unit, shall be credited
against the Accrued Default Obligations Agent is required to pay under this
subsection 11.2. If such excess proceeds exceed the Accrued Default Obligations,
or, if Agent has paid all amounts required to be paid under this subsection
11.2, such excess shall be paid by Owner to Agent. If Agent converts any such
Unit Premises, Unit Improvements, Unit FF&E or Unit after an Event of

Default, or if such Unit Premises, Unit Improvements, Unit FF&E or Unit is lost
or destroyed, in addition to the Accrued Default Obligations, Owner may cause
such Agent to pay to Owner, and Agent shall pay to Owner, as liquidated damages
and not as a penalty, an amount equal to 84.5% of the Unit Acquisition Cost of
such Unit Premises, Unit Improvements, Unit FF&E or Unit.

                  (g) In the event of a sale pursuant to this subsection 11.2,
upon receipt by Owner of the amounts payable hereunder, Owner shall transfer all
of Owner's right, title and interest in and to the Unit Premises, Unit
Improvements, Unit FF&E and Unit to the purchaser thereof.

                  (h) In addition to its other rights in this subsection 11.2,
Owner may exercise its various rights under the Operating Agreement, the Gas
Contract, the Ancillary Facility Agreements or any Construction Agreement or
transfer such rights to the purchaser in a sale.

                  (i) No remedy referred to in this subsection 11.2 is intended
to be exclusive, but each shall be cumulative and in addition to any other
remedy referred to above or otherwise available to Owner at law or in equity,
and the exercise in whole or in part by Owner of any one or more of such
remedies shall not preclude the simultaneous or later exercise by Owner of any
or all such other remedies. No waiver by Owner of any Event of Default hereunder
shall in any way be, or be construed to be, a waiver of any future or subsequent
Event of Default.

                  11.3 Events of Unit Termination. The occurrence of any of the
following shall constitute an Event of Unit Termination with respect to a Unit:

                  (a) Nonconforming Work. If the construction of the Unit
         Improvements, or any part thereof, deviates from the Unit Plans and
         results in a material diminution in the value of any Unit Premises,
         Unit Improvements, Unit FF&E or Unit or there shall be any structural
         defect in any Unit Improvement and Agent fails to correct such
         nonconforming work or structural defect in a reasonably prompt and
         satisfactory fashion after notice and demand by Owner.

                  (b) Failure to Complete. If as of the close of business on a
         Unit Completion Date the related Unit Improvements have not for
         whatever reason (including an event of force majeure deferring
         completion beyond the Force Majeure Delay) been completed as herein
         provided, or if the Certificate of Substantial Completion and AFL Unit
         Leasing Record have not been executed and delivered by the respective
         Unit Completion Date, or if Owner shall reasonably determine during the
         course of construction that the Unit Improvements cannot for whatever
         reason (including an event of force majeure deferring completion beyond
         the Force Majeure Delay) be completed by the Unit Completion Date.

                  (c) Unsatisfactory Title. If at any time title to the Ammonia
         Project or any other Unit is not reasonably satisfactory to Owner by
         reason of any Lien,

         encumbrance, or other environmental defect affecting title, except for
         Permitted Liens, and such Lien, encumbrance or other defect is not
         corrected by and at the expense of Agent within ninety (90) days after
         notice to Agent.

                  (d) Other Security Agreements. If (i) Agent executes any
         chattel mortgage or other security agreement on any materials, fixtures
         or articles of personal property used in the construction or operation
         of the Unit Improvements or if any such materials, fixtures or articles
         are purchased pursuant to any conditional sales contract or other
         security agreement or otherwise so that the title thereto will not vest
         in Owner free from encumbrance or (ii) Agent does not furnish to Owner
         upon request the contracts, bills of sale, statements, receipted
         vouchers and other agreements and documents, or any of them, under
         which Owner claims title to such materials, fixtures or articles.

                  (e) Permits. If Agent shall fail in respect of the Ammonia
         Project to obtain or be unable to obtain any material Permit, or if any
         Permit shall be revoked or otherwise cease to be in full force and
         effect unless, if such revocation or cessation shall not be due to
         Agent's negligence or willful misconduct, Agent shall have obtained
         reinstatement or reissuance of such Permit within thirty (30) days
         after the revocation or expiration thereof, or if such reinstatement or
         reissuance is of a nature that it cannot be completely effected within
         thirty (30) days, Agent shall have diligently commenced application for
         such reinstatement or reissuance and shall thereafter be diligently
         proceeding to complete said reinstatement or reissuance.

                  11.4 Owner's Rights upon Event of Unit Termination. (a) If any
Event of Unit Termination with respect to a Unit shall occur, Owner shall have
no further obligation to make advances to Agent with respect to such Unit, and
Agent shall, upon written notice by Owner of such Event of Unit Termination,
either (i) purchase such Unit within ninety (90) days after written notice by
Owner of such Event of Unit Termination at a price equal to the Unit Acquisition
Cost for such Unit, or (ii) pay to Owner, within five (5) Business Days of
Owner's written notice of such Event of Unit Termination (the "Surrender Date"),
an amount equal to 89.9% of the Unit Acquisition Cost of such Unit and to be
subject to the requirements of paragraph (b) of this subsection 11.4. In the
event Agent elects to purchase such Unit from Owner, at the time of such sale,
Agent shall be required, in addition to its obligation to pay all amounts
contemplated by subsection 9.5 hereof, to pay to Owner Owner's obligations,
costs, losses, damages, and expenses (including, without limitation, taxes and
reasonable attorneys' fees and expenses) sustained by Owner in good faith by
reason of such Event of Unit Termination and exercise of Owner's rights under
this subsection 11.4.

                  (b) In the event Agent elects to proceed under clause (ii) of
subsection 11.4(a) and makes the payment contemplated thereby, Owner may sell
such Unit to a third party and Agent shall have no further right, claim or
interest in such Unit. If Owner shall fail to sell such Unit within seven (7)
days of the Surrender Date, the Assignee shall have the right, but not the
obligation, to sell such Unit to a third party. The proceeds of

sale received by Owner or such Assignee, as the case may be, from any sale of
such Unit shall be retained by Owner or such Assignee, as the case may be,
provided that if the proceeds of sale exceed 10.1% of the Unit Acquisition Cost
of such Unit, such excess shall be paid by Owner or such Assignee, as the case
may be, to Agent net of all amounts to be paid by Agent to Owner pursuant to the
last sentence of subsection 11.4(a) hereof.

                  11.5 Casualty Events. The occurrence of any of the following
shall constitute a Casualty Event with respect to a Unit:

                  (a) Damage or Destruction. If any Unit Improvements are
partially or totally damaged or destroyed by fire or any other cause and the
restoration thereof cannot reasonably be expected to be completed so that the
Unit Improvements will be completed on or before the applicable Unit Completion
Date, subject to any Force Majeure Delay.

                  (b) Takings. If the use, occupancy or title to any Unit is
taken, requisitioned or sold in, by or on account of actual or threatened
eminent domain or confiscation or similar proceedings or other action by any
Governmental Authority (such events collectively referred to as a "Taking") and
such Taking affects a substantial portion of a Unit. Upon receipt of proceeds
from any award or sale made in connection with such Taking, so long as no Event
of Default or Potential Default has occurred and is continuing, and so long as
Agent has made all payments to Owner required under subsection 11.6 hereof,
Owner shall remit to Agent the net amount of such proceeds remaining after
reimbursement for all costs and expenses (including, without limitation,
reasonable attorneys' fees) incurred by Owner in connection with the negotiation
and settlement of any proceedings related to such Taking. If such proceeds are
received prior to Agent making the payments required under subsection 11.6
hereof, the net proceeds shall be applied to the amount payable thereunder. A
Taking shall be deemed "to affect a substantial portion" of a Unit if after such
Taking such Unit is, or will be, in Agent's reasonable judgment, unusable for
Agent's ordinary business purposes.

                  11.6 Owner's Rights upon the occurrence of a Casualty Event.
If any Casualty Event shall occur, (i) Agent shall promptly notify Owner in
writing of such event, (ii) on a date designated by Agent, which shall be a date
within ninety (90) days following such event, Agent shall pay to Owner an amount
equal to 84.5% of the Unit Acquisition Cost of such Unit and (iii) Agent shall
be required, in addition to its obligation to pay all amounts contemplated by
subsection 9.5 hereof, to pay to Owner Owner's obligations, costs, losses,
damages, and expenses (including, without limitation, taxes and reasonable
attorneys' fees and expenses) sustained by Owner by reason of such Casualty
Event and exercise of Owner's rights under this subsection 11.6. Insurance and
condemnation proceeds, if any, received by Owner that, together with the amounts
paid by Agent to Owner pursuant to clause (ii) of the preceding sentence, exceed
the Unit Acquisition Cost of such Unit, shall be paid by Owner to Agent upon
payment by Agent of all amounts referred to in clause (iii) of the preceding
sentence.

                  of subparagraphs (b), (c) and (d) of Section 11 of the Lease,

thereof, except that this Agreement shall substitute the terms in the same
manner as described in subparagraph (a)(ii) above.

                  SECTION 13. LEASEHOLD INTERESTS

                  The provisions of Section 28 of the Lease shall govern each
Ground Lease hereunder, including without limitation the Site Lease, the
Sublease and each additional lease under which a leasehold interest in a Unit
Premises is subleased to Agent or an Affiliate of Agent hereunder, except this
Agreement shall substitute the terms "Owner" for "the Lessor", "Agent" for "the
Lessee", "Unit Premises, Unit Improvements, Unit FF&E and Unit" for "Parcel of
Property" and "Section 13" for "Section 28".

                  SECTION 14. PURCHASES

                  In connection with, and as a condition to, the purchase of any
Unit Premises, Unit Improvements, Unit FF&E or Unit pursuant hereto, (i) Agent
shall pay at the time of purchase, in addition to the Unit Acquisition Cost and
all other amounts payable by Agent under this Agreement, and without limitation
of any of its obligations hereunder or under any other Operative Document, all
transfer taxes, transfer gains taxes, mortgage recording tax, if any, recording
and filing fees and all other similar taxes, fees, expenses and closing costs
(including reasonable attorneys' fees) in connection with the conveyance of such
Unit Premises, Unit Improvements, Unit FF&E or Unit to Agent and all other
amounts owing hereunder, and (ii) when Owner transfers title, such transfer
shall be on an as-is, non-installment sale basis, without warranty by, or
recourse to, Owner, except that such title shall be free of any Liens resulting
from Owner's willful or knowing act or omission not contemplated by this
Agreement, the Lease or the transactions contemplated thereby.

                  SECTION 15. CHARACTER OF AMMONIA PROJECT

                  It is the intention of Owner and Agent that the components of
the Ammonia Project identified as personal property components in Exhibit J
hereto maintain their character as personal property for commercial law
purposes. Agent shall take all reasonable action to maintain such character and
shall obtain and record such instruments and take such steps as may be necessary
to prevent any Person from acquiring any rights in such components by reason of
such components being deemed to be real property.

                  SECTION 16. PERMITTED CONTESTS

                  (a) Agent shall not be required, nor shall Owner have the
right, to pay, discharge or remove any tax, assessment, levy, fee, rent, charge,
Lien or encumbrance, or to comply or cause any Unit Premises, Unit Improvements
item of Unit FF&E or Unit to comply with any Legal Requirement applicable to any
Unit Premises, Unit Improvements item of Unit FF&E or Unit or the occupancy, use
or operation thereof, so long as no Event of Default exists under this
Agreement, and, in the judgment of Agent's counsel, Agent shall have reasonable
grounds to contest the existence, amount, applicability or

validity thereof by appropriate proceedings, which proceedings in the reasonable
judgment of Owner, (i) shall not involve any material danger that any Unit
Premises, Unit Improvements, item of Unit FF&E or Unit would be subject to sale,
forfeiture, loss or loss of use as a result of failure to comply therewith, (ii)
shall not affect the payment of any sums due and payable hereunder or result in
any such sums being payable to any Person other than Owner or any Assignee,
(iii) will not place Owner in any danger of any monetary civil liability which
is not adequately indemnified (Agent's obligations under Section 12 of this
Agreement shall be deemed to be adequate indemnification if no Event of Default
exists) or any other material civil liability or penalty or to any criminal
liability, (iv) if involving taxes, shall suspend the collection of the taxes,
and (v) shall be permitted under and be conducted in accordance with the
provisions of any other instrument to which Agent or any Unit Premises, Unit
Improvements, item of Unit FF&E, or Unit is subject and shall not constitute a
default thereunder (the "Permitted Contest"). Agent shall conduct all Permitted
Contests in good faith and with due diligence and shall promptly after the final
determination (including appeals) of any Permitted Contest, pay and discharge
all amounts which shall be determined to be payable therein. Owner shall at
Agent's expense cooperate in good faith with Agent with respect to all Permitted
Contests conducted by Agent pursuant to this Section 16, including without
limitation in assisting in the preparation of, and participating in, filings
related to such Permitted Contests.

                  (b) At least ten (10) days prior to the commencement of any
Permitted Contest, Agent shall notify Owner in writing thereof if the amount in
contest exceeds $1,000,000, and shall describe such proceeding in reasonable
detail. In the event that a taxing authority or subdivision thereof proposes an
additional assessment or levy of any tax for which Agent is obligated to
reimburse Owner under this Agreement, or in the event that Owner is notified of
the commencement of an audit or similar proceeding which could result in such an
additional assessment, then Owner shall in a timely manner notify Agent in
writing of such proposed levy or proceeding.

                  (c) Owner and Agent agree that no Event of Default, Potential
Default, Event of Unit Termination or Potential Event of Unit Termination shall
be deemed to have occurred if the existence of the event causing such Event of
Default, Potential Default, Event of Unit Termination or Potential Event of Unit
Termination, as the case may be, is being contested by Agent as a Permitted
Contest in accordance with the terms of this Section 16.

                  SECTION 17. SALE OR ASSIGNMENT BY OWNER

                  (a) Owner shall have the right to obtain equity and debt
financing for the acquisition and ownership of any Unit Premises, Unit
Improvements, Unit FF&E and Unit by selling or assigning its right, title and
interest in any or all amounts due from Agent or any third Person under this
Agreement; provided, that any such sale or assignment shall be subject to the
rights and interests of Agent under this Agreement.

                  (b) Any Assignee shall, except as otherwise agreed by Owner
and Assignee, have (to the exclusion of Owner) all the rights, powers,
privileges and remedies

of Owner hereunder, and Agent's obligations as between itself and such Assignee
hereunder shall not be subject to any claims or defense that Agent may have
against Owner, other than the defense of payment or satisfaction of the
obligation; provided that the foregoing shall not be deemed to be a waiver of
any claims Agent may have against Owner. Upon written notice to Agent of any
such assignment, Agent shall thereafter make payments of any and all sums due
hereunder to Assignee, to the extent specified in such written notice, and only
such payments to the applicable Assignee shall discharge the obligation of Agent
hereunder and only to the extent of such payments. Anything contained herein to
the contrary notwithstanding, no Assignee shall be obligated to perform any
duty, covenant or condition required to be performed by Owner hereunder, and any
such duty, covenant or condition shall be and remain the sole obligation of
Owner.

                  SECTION 18. GENERAL CONDITIONS

                  The following conditions shall be applicable throughout the
term of this Agreement:

                  18.1 Survival. All indemnities, representations and warranties
and the obligation to pay Additional Rent (as defined in the Lease) shall
survive the expiration or other termination hereof.

                  18.2 No Waivers. No advance hereunder shall constitute a
waiver of any of the conditions of Owner's obligation to make further advances
nor, in the event Agent is unable to satisfy any such condition, shall any
waiver of such condition have the effect of precluding Owner from thereafter
declaring such inability to be an Event of Default as herein provided. Any
advance made by Owner and any sums expended by Owner pursuant to this Agreement
shall be deemed to have been made pursuant to this Agreement, notwithstanding
the existence of an uncured Event of Default. No advance at a time when an Event
of Default exists shall constitute a waiver of any right or remedy of Owner
existing by reason of such Event of Default, including, without limitation, the
right to refuse to make further advances.

                  18.3 Owner and Assignee Sole Beneficiaries. All conditions of
the obligation of Owner to make advances hereunder are imposed solely and
exclusively for the benefit of Owner and Assignee and their assigns and no other
Person shall have standing to require satisfaction of such conditions in
accordance with their terms or be entitled to assume that Owner will refuse to
make advances in the absence of strict compliance with any or all thereof and no
other Person shall, under any circumstances, be deemed to be a beneficiary of
such conditions, any or all of which may be freely waived in whole or in part by
Owner, with the consent of Assignee, at any time if in its sole discretion, it
deems it advisable to do so. Inspections and approvals of any Unit Plans, Unit
Premises, Unit Improvements, Unit FF&E, and Unit and the workmanship and
materials used therein impose no responsibility or liability of any nature
whatsoever on Owner, and no Person shall, under any circumstances, be entitled
to rely upon such inspections and approvals by Owner for any reason.

                  18.4 No Offsets, Etc. The obligations of Agent to pay all
amounts payable pursuant to this Agreement shall be absolute and unconditional
under any and all circumstances of any character (including, without limitation,
the circumstances set forth in clauses (A) through (K) below), and such amounts
shall be paid without notice, demand, defense (except the defense of prior
payment), setoff, deduction or counterclaim and without abatement, suspension,
deferment, diminution or reduction of any kind whatsoever, except as herein
expressly otherwise provided. Without limitation of the foregoing, the
obligation of Agent to lease and pay Basic Rent (as defined in the Lease) for a
Unit upon Substantial Completion is without any warranty or representation,
express or implied, as to any matter whatsoever on the part of Owner or any
Assignee or any Affiliate of either, or anyone acting on behalf of any of them.

                  AGENT HAS SELECTED AND SHALL SELECT ALL UNIT PREMISES, UNIT
IMPROVEMENTS, UNITS AND ITEMS OF UNIT FF&E CONSTRUCTED, ACQUIRED OR ORDERED ON
THE BASIS OF ITS OWN JUDGMENT. NEITHER OWNER NOR ANY ASSIGNEE NOR ANY AFFILIATE
OF EITHER, NOR ANYONE ACTING ON BEHALF OF ANY OF THEM, MAKES ANY REPRESENTATION
OR WARRANTY OF ANY KIND WHATSOEVER, EXPRESS OR IMPLIED, INCLUDING, WITHOUT
LIMITATION, AS TO THE SAFETY, TITLE, CONDITION, QUALITY, QUANTITY, FITNESS FOR
USE, MERCHANTABILITY, CONFORMITY TO SPECIFICATION, OR ANY OTHER CHARACTERISTIC,
OF ANY UNIT PREMISES, UNIT IMPROVEMENTS, UNIT OR ITEM OF UNIT FF&E, OR AS TO
WHETHER ANY UNIT PREMISES, UNIT IMPROVEMENTS, UNIT OR ITEM OF UNIT FF&E OR THE
OWNERSHIP, USE, OCCUPANCY OR POSSESSION THEREOF COMPLIES WITH ANY LAWS, RULES,
REGULATIONS OR REQUIREMENTS OF ANY KIND.

                  AS BETWEEN OWNER AND AGENT, ANY ASSIGNEE OR ANY INDEMNIFIED
PERSON, AGENT WAIVES ANY AND ALL DEFENSES (EXCEPT THE DEFENSE OF FINAL AND
INDEFEASIBLE PRIOR PAYMENT), SET-OFFS, DEDUCTIONS, COUNTERCLAIMS (OTHER THAN
COMPULSORY COUNTERCLAIMS) (OR OTHER RIGHTS), EXISTING OR FUTURE, TO ITS
OBLIGATION TO PAY ALL AMOUNTS PAYABLE HEREUNDER, INCLUDING, WITHOUT LIMITATION,
ANY RELATING TO:

                  (A) THE SAFETY, TITLE, CONDITION, QUALITY, QUANTITY, FITNESS
FOR USE, MERCHANTABILITY, CONFORMITY TO SPECIFICATION, OR ANY OTHER QUALITY OR
CHARACTERISTIC OF ANY UNIT PREMISES, UNIT IMPROVEMENTS, UNIT OR ITEM OF UNIT
FF&E, LATENT OR NOT;

                  (B) ANY SET-OFF, COUNTERCLAIM (OTHER THAN COMPULSORY
COUNTERCLAIMS), RECOUPMENT, ABATEMENT, DEFENSE (EXCEPT THE DEFENSE OF FINAL AND
INDEFEASIBLE PRIOR PAYMENT) OR OTHER RIGHT WHICH AGENT MAY HAVE AGAINST OWNER,
ANY ASSIGNEE, OR ANY INDEMNIFIED PERSON FOR ANY REASON WHATSOEVER ARISING OUT OF
THIS OR ANY OTHER TRANSACTION OR MATTER;

LAW, ANY AND ALL RIGHTS WHICH IT MAY NOW HAVE OR WHICH AT ANY TIME HEREAFTER MAY
BE CONFERRED UPON IT, BY STATUTE OR OTHERWISE, TO TERMINATE, CANCEL, QUIT,
RESCIND OR SURRENDER THIS AGREEMENT EXCEPT IN ACCORDANCE WITH THE EXPRESS TERMS
HEREOF. The making of payments under this agreement by Agent (including without
limitation payments pursuant to Section 12 hereof) shall not be deemed to be a
waiver of any claim or claims that Agent may in a separate action assert against
Owner or any other person. Owner agrees to repay Agent amounts paid to Owner to
the extent such payments were in error and are not required by any of the terms
and provisions of this Agreement.

                  18.5 No Recourse. (a) Owner's obligations hereunder are
intended to be the obligations of a limited partnership and of the corporation
which is the general partner thereof only and no recourse for the payment of any
amount due under this Agreement or any other Operative Document, or for any
claim based thereon or otherwise in respect thereof, shall be had against any
limited partner of Owner or any incorporator, shareholder, officer, director or
Affiliate, as such, past, present or future, of such corporate general partner
or of any corporate limited partner or of any successor corporation to such
corporate general partner or any corporate limited partner of Owner, or against
any direct or indirect parent corporation of such corporate general partner or
of any limited partner of Owner or any other subsidiary or Affiliate or any such
direct or indirect parent corporation or any incorporator, shareholder, officer
or director, as such, past, present or future, of any such parent or other
subsidiary or Affiliate, it being understood that Owner is a limited partnership
formed for the purpose of the transactions involved in and relating to this
Agreement, the Lease and the Operative Documents on the express understanding
aforesaid. Nothing contained in this subsection 18.5(a) shall be construed to
limit the exercise or enforcement, in accordance with the terms of this
Agreement, the Lease and the Operative Documents and any other documents
referred to herein, of rights and remedies against the limited partnership or
the corporate general partner of Owner or the assets of the limited partnership
or the corporate general partner of Owner.

or director, or Affiliate, as such, past, present or future of such corporate
general partner or limited partner or of any successor corporation to such

                                                      PROJECT

                    DESCRIPTION OF THE PROPERTY TO BE LEASED



Ammonia Plant Project

     The project is to build at the existing Arcadian complex in Trinidad a
1,850 metric tonne per day ("MTPD") ammonia plant.  Ammonia will be produced as
refrigerated product going to the new atmospheric refrigerated storage tankage.
The plant will be operated by Arcadian Trinidad Limited (ATL) and will be
engineered, procured, and constructed by The M. W. Kellogg Company ("MWK").

     The project will utilize MWK's 1,850 MTPD ammonia process based on the low
energy natural gas reforming process offered and licensed by MWK.

     The ammonia plant will be designed to produce 1,850 MTPD ammonia at -28
degrees F for storage in non-pressurized tanks.  Processing steps consist of
the following:

     1.    Raw Synthesis Gas Preparation - Raw synthesis gas is produced from
           natural gas as follows: compression, preheating and desulfurization
           is followed by steam reforming of the hydrocarbons in the natural
           gas in the primary reformer furnace.  Auto thermal reforming in the
           secondary reformer where the remainder of the natural gas is
           converted to hydrogen, carbon monoxide and carbon dioxide while
           introducing sufficient process air to provide the nitrogen required
           for ammonia synthesis.  The carbon
<PAGE>   100
           monoxide is further reformed to carbon dioxide and hydrogen in shift
           reactor utilizing steam.

     2.    Synthesis Gas Purification - In this section, the raw synthesis gas
           is processed to remove carbon dioxide and carbon monoxide yielding a
           highly pure hydrogen-nitrogen rich synthesis gas.  The carbon
           dioxide removal is accomplished by use of an improved Benfield
           Low-Heat process (licensed by VOP).  Final removal of residual
           carbon dioxide and carbon monoxide is accomplished by methanation.

     3.    Purified Synthesis Gas Compression and Ammonia Synthesis - The above
           gas along with a recycled hydrogen stream is then compressed in a
           single case centrifugal compressor, a recycle wheel also compresses
           the loop circulating gases.  The combined gases are then preheated
           before going to the ammonia reactor for conversion to ammonia.
           After heat recovery, the reactor effluent is cooled with cooling
           water and then ammonia refrigerant to condense the ammonia from the
           gases.  The liquid ammonia formed is depressurized and sent to
           refrigerated ammonia storage.

     The plant will contain a new control room and motor control center located
at its battery limits.  No new administration buildings or offices will be
required.  There will be no changes to the existing urea facility or the ship
loading dock.
<PAGE>   101
     All normal plant utilities, including fresh water, potable water, cooling
water, main and emergency power, and fire water will be provided as part of
this project.  Such services will also involve an operating agreement with ATL.

         amount specified for such progress payment date in Annex _____.
         Disputes as to percentages of progress shall be resolved as soon as

         CONTRACTOR shall submit invoices in form and accompanied by supporting
         documentation reasonably satisfactory to OWNER, for each progress
         payment specified in Annex ____.  Subject to the terms and conditions

         thereof has been satisfactorily completed in accordance with the terms
         and conditions of this Agreement; or (iii) limit or otherwise affect
         OWNER's rights and remedies hereunder or otherwise, or CONTRACTOR's
         obligations hereunder.

2.4      In order to assure performance of its obligations under this
         Agreement, CONTRACTOR agrees that OWNER shall retain certain amounts
         from payments due CONTRACTOR hereunder.  OWNER shall retain an amount
         equal to ____% from each progress payment hereunder.  The retained
         monies shall be held in a bookkeeping account maintained by OWNER
         ("Retainage Account"). OWNER shall segregate the funds posted to the
         Retainage Account.  The amounts posted to the Retainage Account shall
         bear simple interest at ______.  All interest shall become part of the

         actual retainage, CONTRACTOR may, at CONTRACTOR's expense, post
         Irrevocable Standby Letters of Credit in form and substance
         satisfactory to OWNER (and its lenders), in amounts equal to _____% of
         each progress payment as described above.  If from time to time
         CONTRACTOR fails to perform its obligations under this Agreement in
         accordance with the terms and conditions hereof, OWNER shall notify
         CONTRACTOR and CONTRACTOR shall promptly remedy any such failure.  If
         CONTRACTOR fails to promptly remedy any such failure, OWNER shall have

         hereunder or otherwise, to withdraw such amounts from the Retainage
         Account, or draw such amounts under such letters of

         credit, as may be necessary to remedy any such failures.  OWNER shall
         also have the right to withdraw such amounts, or draw such amounts
         under such letters of credit, as may be necessary to provide for the
         release of any Encumbrance filed by any of CONTRACTOR's
         Subcontractors, agents, suppliers, Vendors or workers in connection
         with the Work.   If retainage is used, CONTRACTOR shall be paid the
         funds remaining in the Retainage Account following the expiration of
         30 days following the later of the Date of Mechanical Completion, or
         payment in full of all of CONTRACTOR's and Engineering Contractor's
         Subcontractors, agents, suppliers, Vendors and workers.  If such
         letters of credit are used, letters of credit shall remain in effect
         until the later of the two events referenced immediately above.

         Site and Complex in full compliance with all applicable laws, rules,
         regulations and orders of any governmental authority with
         jurisdiction.  OWNER reserves the right to suspend the Work, or any
         portion thereof, if, in its sole discretion, it considers CONTRACTOR's
         actions (or those of its agents or subcontractors) to be
         environmentally irresponsible.

5.8      While on property which constitutes or includes the Site or Complex,
         CONTRACTOR's employees, Subcontractors and agents, and their
         employees, shall confine themselves to areas designated by OWNER.
         CONTRACTOR agrees to place and shall require that its Subcontractors
         and agents and their employees place the highest importance on safety
         and environmental responsibility and exercise all reasonable care
         during the prosecution of the Work.

5.9      CONTRACTOR and CONTRACTOR's employees, agents, Subcontractors and
         their employees will be subject to any and all security rules and
         regulations, badge and pass requirements (including vehicle
         inspections), and safety programs and procedures (including, without
         limitation, Complex Rules and Regulations) that may be in effect at
         the Complex.  CONTRACTOR shall be responsible for the safety of its
         employees, Subcontractors, and agents and their employees, and shall
         take (and cause its agents and Subcontractors to take) all reasonable
         actions and precautions (in connection with the prosecution of the
         Work) to provide for the safety of persons and the protection of
         property in the areas where Work is being performed under CONTRACTOR's
         or any Subcontractor's control.  CONTRACTOR shall initiate and
         maintain all safety precautions and programs necessary to comply with
         applicable health and safety laws, rules and regulations (whether
         federal, state, international or otherwise), and with Complex Rules
         and Regulations concerning health and safety.  Further, CONTRACTOR
         will cause its agents and employees (and those of its Subcontractors
         and agents) to attend all safety orientation and training sessions
         required under Complex Rules and Regulations prior to the commencement
         of Work at the Complex.  OWNER reserves the right to suspend any
         portion of Work if, in its sole discretion, it considers CONTRACTOR's
         actions to be unsafe.

5.10     In the event of any emergency endangering life, health, safety or
         property related to and during the prosecution of Work at the Site,
         CONTRACTOR shall take all actions as may be reasonably necessary to
         prevent, avoid or mitigate injury, damage or loss and shall, as soon
         as possible, report any such incidents, including CONTRACTOR's
         response thereto, to OWNER.  If, in the opinion of the OWNER,
         CONTRACTOR has failed to take sufficient precautions for the safety of
         workers or the public or the protection of the Work, Plant, Facility,
         Complex, or other property constituting or including the Complex,
         creating, in the sole opinion of OWNER, an emergency requiring
         immediate action, then the OWNER, after notice to CONTRACTOR, may
         cause such sufficient precautions to be taken or provide such
         protection.  The taking or provision of any such precautions or
         protection by OWNER shall be for the account

         of CONTRACTOR and CONTRACTOR shall reimburse OWNER for the cost
         thereof.  

5.11     Although OWNER does not seek nor intend to approve or control
         CONTRACTOR's (or its subcontractors' or agents') selection of
         employees assigned to the Work, OWNER shall have the right to
         disapprove and require the removal from the Work being prosecuted at
         the Site of any employee of CONTRACTOR (or any of its Subcontractors
         or agents) who, in OWNER's sole opinion, is incompetent, careless,
         unqualified, or guilty of violation of Site Rules and Regulations.
         Any employee of CONTRACTOR or any Subcontractor or agent testing
         positive for controlled substances or alcohol abuse shall be removed
         from the project. Implementation of a controlled substance and alcohol
         abuse screening and check policy will be at the discretion of
         CONTRACTOR, including frequency and limitations for determining
         positive results and actual interpretations of testing results;
         provided, however, that CONTRACTOR shall (and shall cause its
         Subcontractors and agents to) institute and maintain those controlled
         substance and alcohol screening and check procedures as may be
         necessary to comply with applicable laws, rules and regulations and
         Complex Rules and Regulations.

5.12     CONTRACTOR's Project Manager and other designated key personnel,
         including construction manager, shall be mutually agreed upon by
         CONTRACTOR and OWNER before starting the Work.

5.13     CONTRACTOR shall require all of its employees, agents and
         Subcontractors and their employees to have all required passports,
         visas, work permits or other necessary documentation to perform any of

              ARTICLE 11 - CONTRACTOR REPRESENTATIONS, WARRANTIES
                                 AND GUARANTEES

11.1     Construction/Erection.  CONTRACTOR represents, warrants and guarantees
         that the construction and erection of the Plant and the Facility, and
         any other Work hereunder, shall be performed in accordance with, and
         shall comply and be consistent with, sound, recognized and generally
         accepted construction and engineering standards and practices, all
         applicable codes, standards and governing authorities, and the other
         requirements of this Agreement.  If at any time within one (1) year
         after the Date of Mechanical Completion, any defect in the
         construction, erection or other Work or other breach of this warranty
         is discovered by OWNER, OWNER shall promptly notify CONTRACTOR
         thereof, and CONTRACTOR shall promptly remedy and correct any such
         defects or breaches (including any associated equipment or machinery
         failures) at its sole risk, cost and expense.  Without limiting the
         generality of the foregoing, to the extent any such defect or breach
         results in a reduction in the Plant's [Facility's] performance level
         demonstrated pursuant to Article 12 and Annex C of the Engineering
         Contract, CONTRACTOR shall restore (or cause to be restored) such
         demonstrated performance level at its sole risk, cost and expense.

11.2     Material and Workmanship.  CONTRACTOR represents, warrants and
         guarantees all equipment, machinery, parts, materials, supplies and
         other items supplied, procured or specified by CONTRACTOR or any
         Vendor or Subcontractor, and all workmanship (including field
         workmanship), labor and services furnished in connection with the Work
         (whether by CONTRACTOR or any Subcontractor) against defects (latent
         or patent) in materials or workmanship, or otherwise, for a period of
         one (1) year after the Date of Mechanical Completion.  If at any time
         during the warranty period, OWNER discovers any defect in such
         equipment . . . materials, etc. or workmanship, or if OWNER determines
         that such equipment . . . materials, etc. or workmanship do not
         otherwise comply with the requirements of this Agreement, OWNER shall
         promptly notify CONTRACTOR thereof, and CONTRACTOR shall [subject to
         the limitations set forth below?] remedy and correct any such defects
         to the reasonable satisfaction of OWNER by repairing or replacing the
         defective equipment . . . materials, etc. or workmanship at
         CONTRACTOR's sole risk, cost and expense.  Without limiting the
         generality of the foregoing, [and notwithstanding the limitations
         below] to the extent any such defect results in a reduction in the
         Plant's [Facility's]
    





                                       15
<PAGE>   125
   
         performance level demonstrated pursuant to Article 12 and Annex C of
         the Engineering Contract, CONTRACTOR shall restore such demonstrated
         performance level at its sole risk, cost and expense.  Except with
         respect to reductions in the Plant's performance level, [?CONTRACTOR
         shall not be obligated to perform any of the aforesaid repairs or
         replacements on each occasion upon which OWNER, after discovering
         defective equipment . . . materials, etc. or workmanship, estimates
         the cost of repair or replacement thereof to be [and the cost actually
         is] ____________________ thousand U.S. Dollars (US$______________) or
         less; provided that in the event the cost of such repairs or
         replacements in the aggregate equal $_____________, CONTRACTOR shall
         be obligated for any further repairs or replacements.  Subject to the
         preceding proviso, on each such occasion OWNER shall be responsible
         for such repair or replacement and shall bear the cost thereof.  If
         OWNER estimates the cost of a repair or replacement to be in excess of
         _________________ thousand U.S.  Dollars (US$____________) and
         CONTRACTOR performs the same and the cost therefor is less than such
         amount, OWNER shall pay to CONTRACTOR the costs of such repair or
         replacement within thirty (30) days after OWNER receives CONTRACTOR's
         invoice therefor.  For the purposes of this Section 11.2 the words
         [?"cost" or "costs" shall mean those amounts which would have been
         paid by OWNER to CONTRACTOR for the aforesaid repairs or replacements
         had they been made pursuant to the costs, rates, charges and
         allowances set forth in Annex D.?]  CONTRACTOR shall not be obligated
         to repair or replace any such workmanship which becomes defective as
         the result of improper operation or maintenance or of operating
         conditions more severe than those contemplated in the original design
         for the Work [set forth in __________].

11.3     Subcontractors and Vendors.  CONTRACTOR shall secure or cause its
         Subcontractors to secure the most favorable industry-standard
         warranties and guarantees possible extending over the longest possible
         time obtainable from Subcontractors and Vendors with respect to
         services, equipment, machinery, parts, materials, supplies and other
         items [technology?] furnished by them.  CONTRACTOR will request, at a
         minimum, that Vendors of equipment, machinery, materials, etc., and
         service providers, furnish a guarantee against defects in materials
         and workmanship of one (1) year after initial use or eighteen (18)
         months after shipping.   All such warranties shall be for the benefit
         of CONTRACTOR and OWNER.

11.4     THE ONLY WARRANTIES APPLICABLE TO THE WORK PERFORMED PURSUANT TO THIS
         AGREEMENT ARE THOSE SET FORTH IN THIS AGREEMENT.  CONTRACTOR EXPRESSLY
         DISCLAIMS ANY IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A
         PARTICULAR PURPOSE OR FITNESS FOR A PARTICULAR USE.

11.5     In no event shall either party or its Affiliates be liable to the
         other or its Affiliates, either individually or jointly and
         irrespective of whether alleged to be due to negligence (including the
         sole negligence of any party or any Affiliate), breach of

         contract, strict liability or any other legal theory, for special,
         punitive or consequential damages (including lost production, lost
         profits, and lost revenues) except to the extent such damages are
         attributable to a party's (or its Affiliate's) intentional conduct;
         provided that such damages shall be recoverable hereunder to the
         extent included in damages asserted pursuant to a Third Party Claim
         [defined in indemnity section] with respect to which a party is
         entitled to indemnity hereunder.


                              ARTICLE 12 - CHANGES

12.1     All Work shall be in accordance with this Agreement, and it is the
         intent of the parties that  Changes be avoided to the extent
         practicable.  To this end, the correction by CONTRACTOR (with OWNER's
         prior approval) of [normal errors and minor changes [What does this
         mean?]]made by CONTRACTOR in the course of the Work shall not be
         deemed to constitute a Change.

12.2     At any time during the course of the Work, OWNER may modify the Scope
         of Work as set forth in this Agreement, by written notice to
         CONTRACTOR.  Without limiting the generality of the foregoing, OWNER
         may make changes in drawings, designs and specifications, issue
         additional instructions, require additional work, or direct the
         omission of Work previously ordered.  When a Change is under
         consideration by OWNER, OWNER shall so notify CONTRACTOR.  OWNER may
         request a "scoping estimate" (one which requires no more than five
         manhours to prepare) before requesting a detailed cost estimate.  If
         OWNER wishes to consider the proposed Change after reviewing the
         scoping estimate, OWNER will request a detailed cost estimate.
         CONTRACTOR shall then prepare and submit a detailed cost estimate
         (including, if deemed necessary by CONTRACTOR, revisions to the Target
         Date and to any of  CONTRACTOR's guarantees which will result
         therefrom).  Once the parties mutually agree on the detailed cost
         estimate, they shall confirm their agreement in writing by means of a
         Change  Order.  OWNER shall compensate CONTRACTOR for preparing all
         estimates made at OWNER's request.

12.3     If any of the events set forth below occur and CONTRACTOR determines
         that the result thereof is or will be a  Change, CONTRACTOR  shall
         promptly submit in writing to OWNER its proposed revision to the
         Contract Price together with  the effect, if any, predicted by
         CONTRACTOR on the Target Date or CONTRACTOR's guarantees.   Once the
         parties mutually agree on such items, they shall promptly thereafter
         agree in writing upon a Change Order.  Such events are:

         (a)     a change in the basic design data or Site data (including
                 soils, feedstock, etc.) from that set forth in this Agreement;

         (b)     suspension of Work by OWNER [provisions governing suspension?];

<PAGE>   127
   
         (c)     Force Majeure events preventing CONTRACTOR's performance
                 hereunder; provided that delays attributable to causes other
                 than Force Majeure events affecting Subcontractors and/or
                 Vendors directly shall not constitute Force Majeure;

         (d)     [VAT?] [?Any change in Trinidad taxes?]; or

         (e)     in connection with the Work, any act, or failure to act, on
                 the part of OWNER or any Affiliate of OWNER or any entity in
                 privity of contract with OWNER or any entity exclusively under
                 OWNER's direction or control.

12.4     CONTRACTOR shall not proceed with any Change until a Change Order has
         been signed by the parties.

12.5     Except to the extent agreed otherwise pursuant to a Change Order, the
         compensation payable to CONTRACTOR for preparing estimates pursuant to
         this Article 13, shall be determined in accordance with Annex _____.


                              ARTICLE  13 - LIENS

13.1     CONTRACTOR shall immediately pay and discharge or shall provide
         security sufficient and satisfactory in itself to pay and discharge
         any obligation CONTRACTOR or any of its Subcontractors or Vendors may
         have, in respect of which any Encumbrance may be levied or is levied
         against the Work, the Engineering Work, the Plant, the Facility,  the
         Site, or the Owner Indemnified Parties. CONTRACTOR shall indemnify,
         defend and hold harmless the Owner Indemnified Parties from and
         against any  such Encumbrance and any and all associated Losses.  If
         at any time OWNER shall receive notice or information of the recording
         of any such  Encumbrance or any evidence of any such Encumbrance which,
         if valid, would constitute a legal charge upon property of OWNER , the
         Plant, the Facility or any part thereof, it shall forthwith
         communicate the receipt of such notice, information or evidence to
         CONTRACTOR.

13.2     If any such Encumbrance remains unsatisfied after the Date of
         Mechanical Completion, CONTRACTOR shall promptly refund to OWNER all
         amounts that OWNER may be compelled to pay in discharging any such
         Encumbrance.

                ARTICLE 14 - USE OF INFORMATION AND CONFIDENTIALITY
[Provisions with respect to Kellogg proprietary data deleted because covered by
off-shore contract]

14.1     [This may need to be expanded]  CONTRACTOR agrees to hold in
         confidence any technical or commercial information supplied to it by
         OWNER or any agent of OWNER in connection with the design,
         construction,  start-up, operation or maintenance of the Facility, or
         otherwise, which information is identified by such OWNER or any agent
         of OWNER in writing to be confidential or proprietary at or prior to
         its disclosure.  Said information shall remain the property of such
         OWNER or agent, and CONTRACTOR shall not disclose such information to
         any third party or use such information for any purpose other than
         performing the Work.

14.2     The provisions of  Sections 14.1 shall not apply to:

         (a)     any information  which, at the time of disclosure, the
                 receiving party can show was in the public domain;

         (b)     any information  which, after disclosure, becomes part of the
                 public domain by publication or otherwise, through no fault of
                 the receiving party;

         (c)     any information  which the receiving party can show by
                 supporting documentation was in its possession at the time of
                 disclosure to it by the disclosing party and had not been
                 acquired directly or indirectly under the obligation of
                 confidence to the disclosing party;

         (d)     any information  furnished to the receiving party rightfully
                 by a third party  not under an obligation of confidentiality
                 to the disclosing party, provided again that the receiving
                 party is in compliance with any restrictions on disclosure or
                 limitation of use imposed by such third party;

         (e)     any information independently developed by employees or
                 consultants of the recipients or its Affiliates who have not
                 had access to such information; or

         (f)     any information required by law, rule, regulation or bona fide
                 legal process to be disclosed, provided that the receiving
                 party making such disclosure shall take all reasonable steps
                 to restrict, and maintain to the extent possible the
                 confidentiality of, such disclosure, and shall provide
                 reasonable notice to the other party whose information is
                 involved in order that such other party may take reasonable
                 steps to oppose the requirement of disclosure.

         For the purpose of this  Section 14.2, any disclosure of such
         information which is specific to the operating or design conditions of
         the Plant shall not be deemed to be within the
    





                                       19

foregoing exceptions merely because it is  contained within the scope of a
broad disclosure.


                             ARTICLE 15 - PATENTS

15.1     Subject to the provisions of this Article  15, CONTRACTOR shall, at
         its sole cost and expense, indemnify, defend and hold  the Licensees
         (as defined in the Engineering Contract) and Owner Indemnified Parties
         harmless in respect of any and all Losses incurred in connection with
         any claim, suit or proceeding based on any claim that the Work as
         incorporated into the Plant, the Facility or any part of any thereof,
         constitutes an infringement or violation of any patent or other
         intellectual property right of a third party, including, without
         limitation, infringement or violation of any copyright, trademark or
         trade secret, and infringement of any patent issued in the United
         States or the Republic of Trinidad and Tobago.

15.2     OWNER agrees to notify CONTRACTOR promptly in writing of any notice or
         claim of  infringement and/or violation as described in  Section
         15.1 above which is received by or brought against OWNER.

15.3     In connection with any claim described in  Section 15.1 above,
         CONTRACTOR reserves the right to acquire for  the Licensees, at
         CONTRACTOR's sole cost and expense, immunity from suit  and license to
         use the offending technology, which are acceptable to the Licensees.
         CONTRACTOR also reserves the right, in connection with such claim, of
         making such  alterations of the Facility, at CONTRACTOR's sole cost
         and expense, as may be required to eliminate the alleged infringement;
         provided such alteration is acceptable to the Licensees and does not
         prevent the Facility from being capable of normal operation, reduce
         the capacity of the Facility, interfere with the Performance
         Guarantees (as defined in the Engineering Contract) or performance
         levels, or cause a default by the Licensees under any contract or
         other obligation.

15.4     Neither CONTRACTOR nor OWNER shall settle or compromise any suit or
         action described in  Section 15.1 above without the written consent of
         the other.

15.5     Except to the extent that substantial deviation by the Licensees from
         information furnished by CONTRACTOR  is the sole cause for a claim of
         infringement, CONTRACTOR shall defend, indemnify and hold  the
         Licensees and Owner Indemnified Parties harmless from and against any
         and all Losses that may be assessed in or become payable under any
         decree or  judgment of any court, or under any arbitral decree or
         other order, including costs and expert and professional fees, with
         respect to any suit or action described in  Section 15.1 above.

15.6     OWNER shall defend, indemnify and hold CONTRACTOR harmless from and
         against any claim that any technology or know-how supplied to
         CONTRACTOR by OWNER wrongly incorporates proprietary technical data or
         infringes letters patent issued to, or otherwise infringes any other
         intellectual property rights of a third party.

15.7     The provisions of  Sections 15.1, 15.5 and 15.6 shall not apply to any
         Vendor's or Subcontractor's wrongful use of proprietary technical data
         or infringement of patents (unless caused by such Vendor's or
         Subcontractor's compliance with specific design requirements imposed
         by CONTRACTOR  or Engineering Contractor).  In the event of any such
         wrongful use or infringement, CONTRACTOR and OWNER shall rely on the
         provisions for indemnity against infringement and other terms
         contained in applicable purchase order, subcontract or other agreement
         with the Vendor or Subcontractor; provided, however, that to the
         extent (i) there exists any excess liability not covered by and
         discharged pursuant to the provisions contained in applicable purchase
         order, subcontract or other agreements with the Vendor or
         Subcontractor, and/or (ii) there are no such provisions, the
         CONTRACTOR shall bear sole and complete responsibility and liability
         for, and shall indemnify the Owner Indemnified Parties with respect
         to, any such wrongful use or infringement.

17.1     CONTRACTOR and Engineering Contractor shall have care, custody and
         control of, and shall be solely responsible for, the  Work in progress
         (including, without limitation, the Plant, the Facility (or any

17.4      [The following may be inconsistent with Arcadian's proposal that
         Kellogg keep completed operations insurance in place for 3 years after

         risk of all loss or damage thereto and releases CONTRACTOR from, and
         agrees to defend, indemnify and hold CONTRACTOR harmless against all

         or concurrent negligence, on the part of  any Owner Indemnified Party.

17.6     With respect to products, materials, or substances (including, without
         limitation, any pollutant, contaminant or hazardous or toxic
         substance, material or waste) introduced to the Site by CONTRACTOR,
         Engineering Contractor, or any Subcontractor or Vendor, CONTRACTOR
         releases and discharges and shall defend, indemnify and hold harmless
         the Owner Indemnified Parties from and against any and all Losses
         arising from or related to any such introduction, including, without
         limitation, any failure to properly handle, store or dispose of any
         such products, materials, substances, etc., irrespective of any
         negligence, including sole or concurrent negligence, on the part of
         any Owner Indemnified Party.  With respect to environmental
         contamination (if any) due to the presence of any pollutant,
         contaminant or hazardous or toxic substance, material or waste at the
         Site, prior to the commencement of Work, OWNER hereby releases and

         Completion [expiration of completed operations coverage?] and which
         are not provided for in Sections [17.1-17.6] above, CONTRACTOR
         releases and discharges and shall defend, indemnify and hold harmless
         the Owner Indemnified Parties therefrom, if such Losses are alleged to
         arise from any act or omission on the part of OWNER, CONTRACTOR, the
         Engineering Contractor, or any Subcontractor or Vendor, and
         irrespective of any negligence, including sole or concurrent
         negligence, on the part of any Owner Indemnified Party.  [Completed
         Operations proposal consistency]  With respect to all such claims,
         etc. as described in the preceding sentence of this  Section 18.7, and
         which arise from occurrences on or after [?expiration of completed
         operations coverage], OWNER shall defend, indemnify and hold
         CONTRACTOR harmless therefrom if such claims, etc. arise from any act
         or omission on the part of OWNER or CONTRACTOR and irrespective of any
         negligence, including sole or concurrent negligence, on the part of
         CONTRACTOR.

17.8     The party making a claim for indemnity under this Article 17
         ("Indemnified Party") shall promptly notify the party obligated to
         indemnify ("Indemnifying Party") of the assertion or commencement of
         any claim, demand, investigation, action, suit or other legal
         proceeding in respect of which indemnity is or may be sought
         hereunder; provided, however, that this notice requirement shall not
         apply to any claim, demand, investigation, action, suit or other legal
         proceeding in which the parties are adversaries.  The failure by the
         Indemnified Party to so notify the Indemnifying Party shall not
         relieve the Indemnifying Party of its obligations under this Article
         17, except

         to the extent, if any, that it has been prejudiced by the lack of 
         timely and adequate notice.

17.9     The Indemnifying Party shall have the right to assume the defense or
         settlement of any third-party claim, demand, investigation, action,
         suit or other legal proceeding (collectively "Third-Party Claims")
         with counsel reasonably satisfactory to the Indemnified Party;
         provided, however, that the Indemnifying Party shall not settle or
         compromise any Third-Party Claim without the Indemnified Party's prior
         written consent thereto.  Notwithstanding the foregoing, (1) the
         Indemnified Party shall have the right, at its option and expense, to
         participate fully in the defense or settlement of any Third-Party
         Claim; and (2) if the Indemnifying Party does not commence and
         continuously and diligently continue to defend or seek the settlement
         of any Third-Party Claim within ten (10) days after it is notified of
         the assertion or commencement thereof, then (a) the Indemnified Party
         shall have the right, but not the obligation, to undertake the defense
         or settlement of such Third-Party Claim for the account of and at the
         risk of the Indemnifying Party, and (b) the Indemnifying Party shall
         be bound by any defense or settlement that the Indemnified Party may
         make as to such Third-Party Claim.  The Indemnified Party shall be
         entitled to join the Indemnifying Party in any Third-Party Claim for
         the purpose of enforcing any right of indemnity hereunder.  The
         Indemnified Party shall cooperate with the Indemnifying Party in the
         defense or settlement of any Third- Party Claim and, at the expense of
         the Indemnifying Party, shall furnish any and all non-privileged
         materials in its possession and endeavor to make any and all witnesses
         under its control available to the Indemnifying Party for any lawful
         purpose relevant to the defense or settlement of any such Third-Party
         Claim.

17.10    With respect to the performance of the Work and Engineering Work
         (whether in the United States or Trinidad and Tobago), CONTRACTOR

         during erection until  Final Completion.  Such insurance shall be
         maintained to cover the full value of the  Facility at risk, subject

         Tobago private limited company, Arcadian Corporation, Arcadian
         Fertilizer, L.P., and such other affiliated and non-affiliated

         lenders to OWNER) as loss payee.  All such insurance policies shall be
         maintained in full force and effect until Final Completion.
         Maintaining the prescribed insurance shall not relieve CONTRACTOR of
         any other obligation or any liability under this Agreement; and
         OWNER's rights and remedies under this Agreement (including, without
         limitation, those under the indemnity provisions hereof) or otherwise,
         shall not be limited or modified by the maintenance by CONTRACTOR of
         the prescribed insurance, OWNER's status as an Additional Insured, or
         OWNER's exercise of rights under this Article 17.  The damages
         limitations set forth in Section ________ [limit w/r/t adjacent
         Facilities] above  shall not limit, and does not apply to, the right

         insurance companies authorized to do business in the appropriate state
         or country and reasonably acceptable to OWNER; (3) otherwise be

         changed, CONTRACTOR shall immediately replace the affected policy with
         an insurance policy as called for in this Article 17; and if
         CONTRACTOR does not comply with this covenant, OWNER may obtain the
         replacement insurance policy and recover all premiums paid therefor
         from CONTRACTOR.  CONTRACTOR shall deliver to OWNER evidence of all
         such insurance in the form of an insurance certificate(s); CONTRACTOR
         shall provide such additional insurance certificates as OWNER may
         reasonably request from time to time.

17.14    If CONTRACTOR subcontracts any part of the Work, the insurance
         provisions of each subcontract shall be in accordance with
         CONTRACTOR's usual practice. CONTRACTOR shall be responsible to ensure
         that its Subcontractors maintain insurance as required in the
         subcontracts during the course of Subcontractor's operations in
         connection with the Work.

17.15    [OWNER shall provide Extended Cargo and Charter's Legal Liability

         US$1,000,000.  CONTRACTOR will provide a list of cargo for each ocean
         freight shipment noting each item's replacement value.]  [Ship to,

          rendered unable, wholly or in part, by force majeure, to carry out
          its obligations under this Agreement, other than to make payments due
          hereunder, it is agreed that upon giving notice and full particulars
          of such force majeure event by telephone (confirmed in writing),
          facsimile transmission or in writing to the other party, as soon as
          possible after the occurrence of the cause relied upon, then the
          obligations of OWNER or CONTRACTOR, so far as they are affected by
          such force majeure event, shall be suspended during the continuance
          of any inability so caused, but for no longer period, and such cause
          so far as possible shall be remedied with all reasonable dispatch.
          The term "force majeure" as employed herein shall mean acts of God,
          acts, omissions to act or delays in action by any governmental
          authority, strikes, lockouts or other industrial disturbances, acts

          equipment or pipelines, and any other unforeseeable causes, similar
          to the kind herein enumerated, not within the reasonable control of
          affected party and which by the exercise of due diligence it is
          unable to prevent or overcome.


                     ARTICLE 19 - TERMINATION [Suspensions]

19.1      OWNER shall have the right to terminate the Work upon not less than
          ten (10) days' prior written notice to CONTRACTOR.  In the event of
          such termination of the Work, CONTRACTOR shall take immediate steps
          to terminate the Work as quickly and efficiently as possible, both in
          the field and elsewhere, and shall cancel all commitments on the best
          possible terms, unless otherwise instructed in writing by OWNER.  In
          the event of such termination by OWNER, CONTRACTOR shall be paid by
          OWNER for:
    

          (a)   all amounts due and payable to CONTRACTOR as of the effective
                date of the termination;

   
          (b)   such reasonable costs which CONTRACTOR incurs for such parts of
                the Work as are specifically authorized by OWNER or which are

                of termination, including a close-out  period (not to exceed 4
                weeks from the effective date of the notice of termination) for

                reassignment of CONTRACTOR's employees to other jobs.  Such
                reassignment shall be accomplished as quickly as possible;

   
          (c)   all termination and cancellation charges incurred in
                terminating commitments made to Subcontractors, Vendors [and
                other third parties?] for the Work prior to the effective date
                of the notice of termination;

          (d)   the cost of nonterminable commitments [any of these?] made to
                Subcontractors, Vendors, and other third parties for the Work
                prior to the effective date of the notice of termination; and

          (e)   [reasonable costs for the travel, living and related costs
                incurred by CONTRACTOR for relocating and reassigning
                CONTRACTOR's personnel who are not ordinarily residents of
                Trinidad and Tobago at the time of the effective date of the
                notice of termination plus any severance or similar payments
                required to be made by CONTRACTOR to such personnel.]

          OWNER's sole liability to CONTRACTOR for termination under this
          Paragraph  16.1 shall be determined in accordance with this  Section
          19.1 and OWNER shall not be liable for any other damages including,
          without limitation, loss of anticipated profits.

          [Do we need a provision for suspensions?]

19.2      If CONTRACTOR shall commit any  breach of any material provision
          hereof and such breach shall not be corrected within ten (10) days
          after written notice from OWNER to CONTRACTOR (or, if such breach is
          not correctable within ten (10) days, then within a reasonable time
          after such notice, not to exceed _____), or if CONTRACTOR shall
          become insolvent, either voluntary or involuntary bankruptcy or
          receivership proceedings [initiated, undismissed?] or make an
          assignment for the benefit of creditors, OWNER may terminate this
          Agreement and complete the Work under substantially similar terms and
          conditions as specified herein in any manner OWNER deems expedient,
          provided that OWNER shall be required to mitigate its damages in so
          completing the Work.  In the event the reasonable and necessary costs
          incurred by OWNER to complete the Work exceed the Contract Price,
          CONTRACTOR shall be required to reimburse OWNER for such excess.

19.3      [Arcadian proposal:  limit to failure to pay undisputed amounts not
          covered by Letter of Credit.]  If OWNER shall commit any substantial
          breach of any material provision hereof, including without limitation
          the payment of any sum due hereunder as and when due, and such breach
          shall not be correct within ten (10) days after written notice from
          OWNER to CONTRACTOR (or, if such breach is not correctable within ten
          days, then within a reasonable time after such notice), or if OWNER
          shall become insolvent, enter voluntary or involuntary bankruptcy or
          receivership proceedings [undismissed] or make an assignment for the
          benefit of creditors, CONTRACTOR may terminate this Agreement.  In

          Paragraph  19.1 above [?plus five percent (5%) of the unpaid portion
          of the Contract Price as of the effective date of termination.?]


                   ARTICLE  20 - ASSIGNMENTS AND SUBCONTRACTS

          Agreement  without the prior written  consent of OWNER.  Any such
          permitted assignment shall not relieve CONTRACTOR of any of its
          liabilities or obligations under this Agreement.  Any assignment,

          terms and conditions of this Agreement.  For all purposes of this
          Agreement, including without limitation Articles
          ____________________________, CONTRACTOR and any such Affiliates
          shall be considered one and the same entity.

          all permits, licenses  and other governmental authorizations that may

          or fees (or related bonds) for all Trinidad Work related materials,
          tools, supplies, consumables, and equipment.   OWNER will pay

          regulations of each jurisdiction in which Work is or may be
          performed.


                      ARTICLE 23 - INDEPENDENT CONTRACTOR

23.1      It is expressly understood and agreed that in the performance of the
          Work, CONTRACTOR is, and shall be an independent contractor, and is
          and shall be solely responsible for the means, method and manner of
          performing the Work, including, without limitation, the selection of
          suitable tools and equipment and a sufficient number of qualified
          employees and subcontractors.  The selection of personnel, their
          training and supervision, their hours of labor, and the compensation
          and benefits to be paid to or provided such personnel shall be
          determined by and shall be the responsibility of CONTRACTOR or its
          Subcontractors or agents, as the case may be.  Under no circumstances
          shall activities or omissions of CONTRACTOR, its agents,
          representatives, or Subcontractors, or CONTRACTOR's employees, be
          considered those of OWNER or its agents, and in no event shall the
          relationship between the  parties (or any party's agent) be construed
          as that of principal and agent, master and servant, joint venturers,
          or employer and employee for any purpose whatsoever.  As an
          independent contractor, any and all personnel utilized directly or

          indirectly by CONTRACTOR shall not be deemed to be employees, agents
          or representatives of OWNER or its agents.  CONTRACTOR acknowledges
          and agrees that it and not OWNER will make or cause to be made any
          payments on behalf of CONTRACTOR, any of its agents or
          Subcontractors, or any of their respective employees.

                           ARTICLE 26 - MISCELLANEOUS

26.1      Entire Agreement.  This Agreement (including the attached annexes)
          constitutes the full understanding of the parties, a complete
          allocation of risks between them, and a complete and exclusive
          statement of the terms and conditions of their agreement
    





                                       34
<PAGE>   144
   
          relating to the subject matter hereof and supersedes any and all
          prior negotiations, understandings and agreements, whether written or
          oral, between the parties with respect thereto, including, without
          limitation, any and all interim arrangements and agreements.  Except
          as otherwise specifically provided in this Agreement, no term,
          condition, usage of trade, course of dealing or performance,
          understanding or agreement purporting to modify, vary, explain or
          supplement the provisions of this Agreement shall be effective or
          binding on the parties, unless the same hereafter is effected in
          accordance with Section 26.2.

26.2      Amendments.  This Agreement may not be altered, modified, amended or
          changed (other than any waiver of any provision hereof, which shall
          be effective only if made in accordance with Section 26.3) in any
          manner, except by a written agreement executed and delivered by all
          parties.  Without limiting the generality of the foregoing, this
          Agreement shall not be altered, modified, amended or changed by any
          terms or provisions of purchase orders, invoices or other documents
          issued, delivered, and/or executed by or to CONTRACTOR or OWNER in
          connection with the Work or otherwise.

26.3      Waivers.  No waiver by any party of any breach of the covenants set
          forth herein or any claim, right or remedy provided for hereunder and
          no course of dealing shall be deemed a waiver of the same or any
          other breach, claim, right or remedy, unless such waiver is in
          writing and is signed by the party sought to be bound.  The failure
          of a party to assert or exercise any claim, right or remedy shall not
          be deemed a waiver of such claim, right or remedy in the future.  Any
          failure by either OWNER or CONTRACTOR at any time or from time to
          time to enforce or insist upon the strict keeping and/or performance
          of any of the terms or conditions of this Agreement, shall not
          constitute a waiver of such terms or conditions, and shall not affect
          or impair such terms or conditions in any way, or the rights of OWNER
          or CONTRACTOR at any time to avail itself of such remedies as it may
          have for any breach or breaches of such terms or conditions.

26.4      Modification and Severability.  If an arbitration tribunal or court
          of competent jurisdiction declares that any provision of this
          Agreement is illegal, invalid or unenforceable, then such provision
          shall be modified automatically to the extent necessary to make such
          provision fully legal, valid and enforceable.  If such arbitration
          tribunal or court does not modify any such provision as contemplated
          herein, but instead declares it to be wholly illegal, invalid or
          unenforceable, then such provision shall be severed from this
          Agreement, and this Agreement, and the rights and obligations of the
          parties hereto, shall be construed as if this Agreement did not
          contain such severed provision, and this Agreement otherwise shall
          remain in full force and effect.
    





                                       35

26.5      Enforceability.  This Agreement shall be enforceable by and against
          CONTRACTOR and OWNER and their respective successors, permitted
          assignees and legal representatives.

26.6      Survival.  Any and all guarantees, representations, warranties,
          standards and specifications concerning the Work, Engineering Work,
          Facility or Plant set forth herein shall survive  (I) the inspection,
          test, acceptance (including acceptance pursuant to Section _____ __
          of the Engineering Contract) and payment for the Work or any portion
          thereof; and (ii) for the maximum period permitted by applicable law
          (subject to the duration limitations set forth in Article _____), the
          termination, suspension or expiration of the Work (or any portion
          thereof) or this Agreement (or any portion thereof).  The provisions
          of Articles ______________ [indemnity, patent, confidentiality], and
          the parties' respective obligations, rights and remedies thereunder,
          shall survive the termination, suspension or expiration of the Work
          (or any portion thereof) or this Agreement (or any portion thereof)
          for the maximum period permitted by applicable law.

26.7      Conflicts.  In the event there are conflicts between the provisions
          set forth in the body of this Agreement and those set forth in
          annexes hereto, the provisions set forth in the body of this
          Agreement shall control.

26.8      Captions.  The captions contained in this Agreement are for
          convenience of reference only and shall not affect in any way the
          meaning, construction or scope of the provisions of this Agreement.

26.9      Joint Venture.  OWNER and CONTRACTOR are not and shall not be deemed
          or construed to be joint venturers, partners, agents, servants,
          employees, fiduciaries or representatives of each other by virtue of
          this Agreement or the performance thereof.

26.10     Equitable Remedies.  The parties acknowledge and agree that
          irreparable damage would occur in the event that material provisions
          of this Agreement were not performed in accordance with their
          specific terms and conditions or were otherwise breached.
          Accordingly, in the event of any breach by a party hereto of any
          covenant contained in this Agreement, the other party shall be
          entitled to equitable relief (including, without limitation, specific
          performance of such covenant), in addition to any and all other
          remedies to which said party may be entitled hereunder or by law.
          Any party's full or partial exercise of any remedy shall not preclude
          any subsequent exercise by said party of the same or any other
          remedy.

26.11     Cumulative Nature.  The respective rights and remedies of the parties
          under this Agreement shall be cumulative of, in addition to, and not
          in limitation of, one another, and any and all other rights and
          remedies which may be available under applicable law.

          AND ENFORCED IN ACCORDANCE WITH THE LAWS OF THE STATE OF TENNESSEE,
          UNITED STATES OF AMERICA, EXCLUDING THE CONFLICT-OF-LAWS PROVISIONS
          THEREOF.  OWNER AND CONTRACTOR SHALL SUBMIT TO THE JURISDICTION OF

          ACTION, SUIT OR OTHER LEGAL PROCEEDING ARISING FROM OR BASED ON THIS
          AGREEMENT.

26.13     Multiple Counterparts.  This Agreement may be executed by the parties
          hereto in multiple counterparts, each of which shall be deemed an
          original for all purposes, and all of which together shall constitute
          one and the same instrument.

26.14     [Required by Merrill Lynch] No Recourse.  OWNER's obligations
          hereunder are intended to be the obligations of the limited
          partnership and of the corporation which is the general partner
          thereof only and no recourse for any obligation of OWNER hereunder,
          or for any claim based thereon or otherwise in respect thereof, shall
          be had against any limited partner of OWNER or any incorporator,
          shareholder, officer or director, or affiliate, as such, past,
          present or future of such corporate general partner or limited
          partner or of any successor corporation to such corporate general
          partner or any corporate limited partner of OWNER, or against any
          direct or indirect parent corporation of such corporate general
          partner or of any limited partner of OWNER or any other subsidiary or

          incorporator, shareholder, officer or director, as such, past,
          present or future, of any such parent or other subsidiary or
          affiliate.  Nothing contained in this section shall be construed to
          limit the exercise or enforcement, in accordance with the terms of
          this Agreement and any other documents referred to herein, of rights
          and remedies against the limited partnership or the corporate general
          partner of OWNER or the assets of the limited partnership or the
          corporate general partner of OWNER.

1.3      In the event of any conflict between the provisions of the Articles of
         this Agreement and the provisions of the Annexes, the provisions of
         the Articles shall prevail.


   
                           ARTICLE 2 - PRICE/PAYMENT

2.1      As full compensation for the performance of the Work hereunder and any
         and all Construction Work under the Construction Contract, inclusive
         of all Subcontractor, Vendor and other third-party fees and charges,
         direct and indirect costs and fees of CONTRACTOR (and of Constructor),

         pay CONTRACTOR progress payments, representing in each case a portion
         of the fixed lump sum price described in Section 2.1 above, as
         contemplated by Annex E hereto.  Such payments shall be based on the
         percentage of  progress reported by
    





                                       5
<PAGE>   156
   
         CONTRACTOR as of  the dates specified in Annex E, and agreed to by
         OWNER.  OWNER shall be required to pay only that progress payment
         amount, for each progress payment date, which is equal to the
         percentage of  progress that OWNER agrees has been completed;
         provided, however, that if OWNER's determination of the percentage of
         progress (for any progress payment other than the final progress
         payment) is within _____% of the percentage of  progress specified for
         such progress payment date in Annex E, then OWNER shall pay the amount
         specified for such progress payment date in Annex E.  Disputes as to
         percentages of progress shall be resolved as soon as reasonably
         possible; provided that OWNER shall be required to pay only those
         amounts representing completed progress as agreed to by OWNER.
         CONTRACTOR shall submit invoices in form and accompanied by supporting
         documentation reasonably satisfactory to OWNER, for each progress
         payment specified in Annex E.  Subject to the terms and conditions of
         this Section 2.3, OWNER shall make required  payments via direct bank
         wire transfer within ______ days after receipt of invoice by OWNER.

2.4      Any payments made hereunder by OWNER shall not (i) preclude OWNER from
         disputing any item or matter, including, without limitation, whether
         the particular percentage of completion in question has in fact been
         achieved; (ii) constitute or be construed as OWNER's acceptance of the
         Plant, Facility, Work, Construction Work or any portion thereof, or
         OWNER's acknowledgment that the Work, Construction Work or any portion
         thereof has been satisfactorily completed in accordance with the terms
         and conditions of this Agreement; or (iii) limit or otherwise affect
         OWNER's rights and remedies hereunder or otherwise, or CONTRACTOR's
         obligations hereunder.

2.5      In order to assure performance of its obligations under this
         Agreement, CONTRACTOR agrees that OWNER shall retain certain amounts
         from payments due CONTRACTOR hereunder.  OWNER shall retain an amount
         equal to ____% from each progress payment hereunder.  The retained
         monies shall be held in a bookkeeping account maintained by OWNER
         ("Retainage Account"). OWNER shall segregate the funds posted to the
         Retainage Account.  The amounts posted to the Retainage Account shall
         bear simple interest at ______.  All interest shall become part of the
         Retainage Account due CONTRACTOR as provided herein.  In lieu of
         actual retainage, CONTRACTOR may, at CONTRACTOR's expense, post
         Irrevocable Standby Letters of Credit in form and substance
         satisfactory to OWNER (and its lenders), in amounts equal to _____% of
         each progress payment as described above.  If from time to time
         CONTRACTOR fails to perform its obligations under this Agreement in
         accordance with the terms and conditions hereof, OWNER shall notify
         CONTRACTOR and CONTRACTOR shall promptly remedy any such failure.  If
         CONTRACTOR fails to promptly remedy any such failure, OWNER shall have
         the right, in addition to any other rights and remedies it may have
         hereunder or otherwise, to withdraw such amounts from the Retainage
         Account, or draw such amounts under such letters of credit, as may be
         necessary to remedy any such failures.  OWNER shall also have the
    





                                       6
<PAGE>   157
   
         right to withdraw such amounts, or draw such amounts under such
         letters of credit, as may be necessary to provide for the release of
         any Encumbrance filed by any of CONTRACTOR's Subcontractors, agents,
         suppliers, Vendors or workers in connection with the Work.   If
         retainage is used, CONTRACTOR shall be paid the funds remaining in the
         Retainage Account following the expiration of 30 days following the
         later of the Date of Mechanical Completion, or payment in full of all
         of CONTRACTOR's and Constructor's Subcontractors, agents, suppliers,
         Vendors and workers.  If such letters of credit are used, letters of
         credit shall remain in effect until the later of the two events
         referenced immediately above.

         report is prepared, detailing the progress made by CONTRACTOR during
         the preceding month toward the achievement of the Target Date.  The
         reports shall include, but shall not be limited to, the following:

         1.      A description of any and all delays which CONTRACTOR 
                 anticipates.

         2.      An updated schedule.

                 complete.

         4.      A narrative of the activities conducted during the month,
                 including action items and problems.

3.4      [There will need to be a corresponding provision in the Construction
         Contract.]  In lieu of providing a performance and payment bond,
         contemporaneously with the execution hereof, CONTRACTOR shall deliver
         to OWNER a guaranty of its parent, Dresser Industries, Inc., a
         Delaware corporation, guaranteeing that CONTRACTOR

         and liabilities of CONTRACTOR or of any Subcontractor, supplier or
         Vendor of CONTRACTOR, protecting OWNER  against Losses by reason of
         the breach of or default in the performance of any such undertakings,
         guarantees, warranties or obligations, and protecting OWNER against
         all claims and Encumbrances for the payment of sums for labor,
         services and materials provided in connection with the Work.   Such
         guaranty shall remain in effect at least until the expiration of all
         warranty periods provided for under Article _______ hereof, and shall
         apply to all matters (otherwise covered by such guaranty) of which
         notice has been provided to CONTRACTOR prior to the expiration of such
         guaranty.

4.1      The Scope of Work, attached hereto as [Annex A] and as otherwise
         described herein, specifically enumerates and describes the Work to be
         performed by CONTRACTOR under this Agreement; provided, however, that
         the Work (and hence the Scope of Work) shall include, without
         limitation, such additional services and items as may be necessary or
         appropriate to enable CONTRACTOR to perform its obligations under this
         Agreement in accordance with the terms and conditions hereof.  It is
         understood and agreed that the Construction Work required to be
         performed in the Republic of Trinidad and Tobago shall be performed by
         Constructor.  Portions of the fixed lump sum price described in
         Article 2 hereof  shall be paid to Constructor to reflect its
         performance of such Construction Work.  Notwithstanding the foregoing,
         CONTRACTOR shall supervise and shall be liable and responsible for the
         performance of the Construction Work by Constructor and for its
         undertakings and obligations under the Construction Contract.


                ARTICLE 5 - CERTAIN CONTRACTOR RESPONSIBILITIES

         construction standards and practices for projects similar in scope and
         size to this project, and otherwise in accordance with the terms and
         conditions of this Agreement.

5.2      In the performance of the Work, CONTRACTOR shall (and shall cause its

<PAGE>   159
   
5.3      CONTRACTOR represents and warrants to OWNER, and covenants and agrees,
         that the Plant, the Facility, the Work, and the Construction Work
         shall be at the time of Final Completion free and clear of any and all
         liens, security interests, charges, and encumbrances (collectively,
         "Encumbrances").

5.4      Risk of loss of and damage to the Work, [the Construction Work], the
         Plant, and the Facility, will be and remain with CONTRACTOR until the
         Date of Mechanical Completion of all Work, the Construction Work, the
         Plant, and the Facility; provided that the insurance policies and
         coverages required under Article _______ shall (except as provided
         therein) remain in effect until Final Completion, and shall continue
         to cover such Losses as provided in such policies.

5.5      Except as provided in Section _______ [Kellogg proprietary data], all
         drawings, specifications, designs, engineering data and studies,
         process data and studies, intellectual property (including all
         patentable and copyrightable materials), and any other data, materials
         or items which are generated, produced or created as part of or in
         connection with the Work, shall be the sole and exclusive property of
         OWNER.  CONTRACTOR shall (and shall cause its Subcontractors, Vendors
         and agents to) (i) provide all such property (and all copies and other
         reproductions thereof) to OWNER by the date of Final Completion; and
         (ii) execute such instruments as OWNER may reasonably require to
         evidence OWNER's ownership of such property.  Neither CONTRACTOR nor
         its Subcontractors, Vendors or agents may retain, use, or otherwise
         exercise dominion over any such property; provided that CONTRACTOR may
         retain a complete set of Work drawings and other Work documents as
         necessary for archives, in order to provide OWNER with information and
         advice in the future concerning the Work performed under this
         Agreement.  Any such retained drawings and documents shall be subject
         to the confidentiality provisions set forth in Section
         _______[Contractor confidentiality obligations], and CONTRACTOR may
         not use such drawings and documents in the performance of services for
         other clients.


              ARTICLE 6 - CONTRACTOR'S DESIGN AND ENGINEERING WORK

6.1      Without limiting the generality of Sections 1.1, 1.2(gg)[Work
         definition], Article 4 and Annex A, CONTRACTOR shall prepare and
         furnish the design, process design and engineering drawings and data
         required to procure the materials, machinery and equipment (including
         operating equipment) and perform related Workfor, and required to
         construct, erect, start-up and operate the Facility, all in accordance
         with the procedures, designs, plans and specifications set forth in
         Annex A and those approved pursuant to Section 6.3.

6.2      The basic design conditions and certain technical and process data for
         the Facility [either have been or will be furnished]  [Aren't these
         set forth in Annex A, "Basis for Design"?] to CONTRACTOR by OWNER or
         by parties in privity of contract with OWNER or have
    





                                       9
<PAGE>   160
         been reviewed and approved by OWNER.  If any further data or
         information of this nature is required by CONTRACTOR, OWNER will
         furnish such data and information to CONTRACTOR without cost to
         CONTRACTOR.  The design of the Facility shall be based upon all of the
         foregoing, and CONTRACTOR shall be entitled to rely upon such data and
         information in the performance of the Work.

   
6.3      Upon completion of CONTRACTOR's [preliminary?] planning engineering
         and design Work with respect to any part of the Facility and prior to
         commencing Work on the final detailed design of such part, CONTRACTOR
         shall submit for OWNER's prior approval plot plans, planning drawings,
         engineering flow sheets and specification sheets (collectively,
         "Drawings and Specifications") [?for major items of operating
         equipment with respect to such part].  Within ten (10) working days
         after receipt, OWNER shall approve or disapprove (and provide comments
         with respect to) all Drawings and Specifications submitted by
         CONTRACTOR.  OWNER's failure to notify CONTRACTOR within ten (10)
         working days after receipt, of approval or disapproval, shall be
         deemed an approval by OWNER.  OWNER's approval, however, shall not
         relieve CONTRACTOR of any of its obligations under this Agreement, or
         limit or impair any of OWNER's rights and remedies hereunder or
         otherwise.  The details for the preceding provisions of this Section
         6.3 are set forth in Annex B.

6.4      OWNER shall have the right to review at its own expense the progress
         of CONTRACTOR's engineering and other Work as it proceeds, and in so
         doing OWNER shall cooperate with CONTRACTOR so as not to increase
         CONTRACTOR's engineering cost.

6.5      CONTRACTOR shall appoint a representative to act on CONTRACTOR's
         behalf in the administration and performance of this Agreement.  Such
         representative will be available to OWNER at all reasonable times, as
         more specifically set forth in Annex B.

6.6      If such Subcontractors are preapproved by OWNER and listed in Annex A,
         CONTRACTOR shall have the right to have engineering, design and
         drafting services performed inside or outside CONTRACTOR's offices by
         Subcontractors who are not employees of CONTRACTOR, but who are under
         CONTRACTOR's supervision; provided, however, such shall not relieve
         CONTRACTOR from any of its obligations under this Agreement.

6.7      Commencing on or about [December _________, 1995], CONTRACTOR
         performed certain services relative to the Facility including
         preliminary engineering, process design and cost estimating.
         CONTRACTOR acknowledges that it has been compensated in full for such
         services (or, CONTRACTOR's sole compensation for such services is
         included in, and is a part of, the lump sum Contract Price.)  Further,
         it is agreed that this Agreement supersedes[Letters] and that such
         services shall be deemed to be Work.  [Does this mean that "effective
         date" should be February 15, 16, 1996?]

              ARTICLE 11 - CONTRACTOR REPRESENTATIONS, WARRANTIES
                                 AND GUARANTEES

11.1     From and after the Date of Mechanical Completion, CONTRACTOR
         represents, warrants and guarantees that the Plant [Facility?] shall
         fulfill the Performance Guarantees.  Such fulfillment of the
         Performance Guarantees shall be demonstrated in Performance Test(s)
         (as defined in Article 12) conducted pursuant to Article 12 and Annex
         C.  If at any time within one (1) year after the Date of Mechanical
         Completion, OWNER determines that the Plant [Facility] or any
         operation or performance thereof does not fulfill the Performance
         Guarantees, then OWNER shall promptly notify CONTRACTOR and, subject
         to the immediately succeeding sentence, CONTRACTOR shall promptly
         correct any such deficiencies at CONTRACTOR's sole risk, cost and
         expense.  In the event any Liquidated Damages become due and are paid
         to OWNER pursuant to Annex C (either because the Plant [Facility]
         achieves only a certain percentage of the Performance Guarantees
         during Performance Test(s) [which in any event shall equal or exceed
         95%], or experiences a decline in such percentage achieved during
         Performance Test(s) [with the level of performance still equaling or
         exceeding 95%] during the one (1) year period referred to above), such
         amounts shall be in lieu of any other claims pursuant to this Section
         11.1 OWNER might have with respect to the performance of the Plant
         [Facility?] [see Annex C].

11.2     Engineering/Design.  CONTRACTOR represents, warrants and guarantees
         that the engineering, process design and design of the Plant and the
         Facility, and any other Work hereunder and Construction Work under the
         Construction Contract, shall be performed in accordance with, and
         shall comply and be consistent with, sound, recognized and generally
         accepted engineering and design standards and practices, all
         applicable codes, standards and governing authorities, and the other
         requirements of this Agreement.  If at any time within one (1) year
         after the Date of Mechanical Completion, any defect in the
         engineering, design or other Work or Construction Work or other breach
         of this warranty is discovered by OWNER, OWNER shall promptly notify
         CONTRACTOR thereof, and CONTRACTOR shall promptly remedy and correct
         any such defects or breaches (including any associated equipment or
         machinery failures) at its sole risk, cost and expense.  Without
         limiting the generality of the foregoing, to the extent any such
         defect or breach results in a reduction in the Plant's [Facility's]
         performance level demonstrated pursuant to Article 12 and Annex C,
         CONTRACTOR shall restore such demonstrated performance level at its
         sole risk, cost and expense.

11.3     Material and Workmanship.  CONTRACTOR represents, warrants and
         guarantees all equipment, machinery, parts, materials, supplies and
         other items supplied,
    





                                       13
<PAGE>   164
   
         procured or specified by CONTRACTOR, and all labor and services
         furnished in connection with the Work or Construction Work against
         defects (latent or patent) in materials or workmanship, or otherwise,
         for a period of one (1) year after the Date of Mechanical Completion.
         If at any time during the warranty period, OWNER discovers any defect
         in such equipment . . . materials, etc. or workmanship, or if OWNER
         determines that such equipment . . . materials, etc. or workmanship do
         not otherwise comply with the requirements of this Agreement, OWNER
         shall promptly notify CONTRACTOR thereof, and CONTRACTOR shall remedy
         and correct any such defects to the reasonable satisfaction of OWNER
         by repairing or replacing the defective equipment . . . materials,
         etc. or workmanship.  Without limiting the generality of the
         foregoing, to the extent any such defect results in a reduction in the
         Plant's [Facility's] performance level demonstrated pursuant to
         Article 12 and Annex C, CONTRACTOR shall restore such demonstrated
         performance level at its sole risk, cost and expense.

11.4     Subcontractors and Vendors.  CONTRACTOR shall secure or cause its
         Subcontractors to secure the most favorable industry-standard
         warranties and guarantees possible extending over the longest possible
         time obtainable from Subcontractors and Vendors with respect to
         services, equipment, machinery, parts, materials, supplies and other
         items [technology?] furnished by them.  CONTRACTOR will request, at a
         minimum, that Vendors of equipment, machinery, materials, etc., and
         service providers, furnish a guarantee against defects in materials
         and workmanship of one (1) year after initial use or eighteen (18)
         months after shipping.   All such warranties shall be for the benefit
         of CONTRACTOR and OWNER.

11.5     Environmental.  CONTRACTOR represents, warrants and guarantees that
         the Plant and Facility shall be designed to meet applicable World Bank
         Environmental Guidelines, September, 1988, and the 1995 proposed World
         Bank Guidelines published as part of the Preliminary Version of the
         World Bank's Industrial Pollution Prevention and Abatement Handbook,
         June 30, 1995.  If within one (1) year after the Date of Mechanical
         Completion, OWNER discovers a defect or other breach of this warranty,
         OWNER shall promptly notify CONTRACTOR, and CONTRACTOR shall remedy
         and correct any such defect or breach at its sole risk, cost and
         expense.

11.6     THE ONLY WARRANTIES APPLICABLE TO THE WORK PERFORMED PURSUANT TO THIS
         AGREEMENT ARE THOSE SET FORTH IN THIS AGREEMENT.  CONTRACTOR EXPRESSLY
         DISCLAIMS ANY IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A
         PARTICULAR PURPOSE OR FITNESS FOR A PARTICULAR USE.

11.7     In no event shall either party or its Affiliates be liable to the
         other or its Affiliates, either individually or jointly and
         irrespective of whether alleged to be due to negligence (including the
         sole negligence of any party or any Affiliate), breach of contract,
         strict liability or any other legal theory, for special, punitive or
         consequential
    





                                       14

         damages (including lost production, lost profits, and lost revenues)
         except to the extent such damages are attributable to a party's (or
         its Affiliate's) intentional conduct; provided that such damages shall
         be recoverable hereunder to the extent included in damages asserted
         pursuant to a Third Party Claim [defined in indemnity section] with
         respect to which a party is entitled to indemnity hereunder.


                 ARTICLE 12 - PERFORMANCE TESTS AND ACCEPTANCE

12.1     [Put in Annex C?]  Within ________ days following the Date of
         Mechanical Completion, OWNER agrees to commence conducting mechanical
         and process performance tests (the "Performance Tests") to determine
         whether the Plant and the Facility perform as required by Section
         12.1, Annex A, or any other provision of this Agreement [or the
         Construction Contract], unless OWNER's failure to timely conduct such
         Performance Tests is caused by CONTRACTOR's actions or inactions or is
         attributable to a Force Majeure event.  Failure to timely commence
         Performance Tests (except as excused hereby) shall be deemed a waiver
         of the rights to such tests.  Prior to the commencement of the
         Performance Tests, detailed methods to be used in the Performance
         Tests [Annex C?] shall be agreed upon in writing by CONTRACTOR and
         OWNER.  Such methods shall be in accordance with normal practice, and
         shall include methods for measuring various process streams by
         calibrated measuring devices, methods for calibrating such measuring
         devices, methods for sampling and analyzing process streams, as well
         as methods for evaluating the results of the measurements and
         analyses.  Further, acceptable tolerances for all results shall be
         specified.  OWNER may, at its option, waive the Performance Tests.  In
         the event the Performance Tests indicate that the Plant, the Facility,
         or any portion of the Work or Construction Work does not meet all the
         requirements of this Agreement [or the Construction Contract], OWNER
         will advise CONTRACTOR, and CONTRACTOR shall as promptly as possible,
         at its sole risk, cost and expense, make (or cause to be made) such
         alterations, adjustments, repairs, or replacements as may be necessary
         or appropriate in order that the Plant, the Facility, the Work, and
         Construction Work meet and comply with all of the requirements of this
         Agreement, and the Construction Contract including, without
         limitation, Section 12.1 and Annex A hereof.

12.2     With respect to the Performance Tests, OWNER shall provide at its
         expense (i) raw materials and utilities in quantities necessary for
         the startup and operation of the Plant; and (ii) operations and
         maintenance personnel necessary for the preparation of the Plant for
         operation and for operating the Plant during commissioning.

12.3     After correction of all deficiencies under Section 12.1, OWNER may, at
         its option, reconduct the Performance Tests.  If such reconducted
         tests indicate deficiencies, the procedures described in Sections
         12.1-12.2 shall be repeated (provided that the ______-day deadline
         shall not apply) until such time as the Plant, the Facility, the Work
         and the Construction Work meet and comply with all the requirements of
         this Agreement
    





                                       15
<PAGE>   166
   
         and the Construction Contract.  OWNER may, at its option, waive
         reconducting any Performance Test.  OWNER will issue CONTRACTOR a
         written Notice of Acceptance of the Plant when all of the following
         conditions have been satisfied:

         A.      All Work, Construction Work, the Plant and the Facility have
                 been completed in accordance with, and meet and comply with,
                 all of the requirements of this Agreement and the Construction
                 Contract, including, without limitation, all guarantees,
                 specifications, standards, representations and warranties set
                 forth herein or therein.

         B.      The completed Work, Construction Work, the Plant and the
                 Facility have passed all Performance Tests, or Performance
                 Tests have been waived.

         C.      There are no Encumbrances outstanding with respect to the
                 Work,  Construction Work, the Plant and the Facility.

         D.      All of CONTRACTOR's and Constructor's Subcontractors and
                 Vendors, suppliers and employees have been paid in full for
                 materials and services provided in connection with the Work or
                 Construction Work.  CONTRACTOR shall deliver to OWNER a
                 certificate indicating that all such payments have been made.

         OWNER's issuance of the Notice of Acceptance of the Plant shall in no
         way (i) relieve, limit or otherwise modify CONTRACTOR's or
         Constructor's liability for their respective  obligations and
         responsibilities under this Agreement and the Construction Contract;
         or (ii) limit or modify any rights and remedies that OWNER has under
         this Agreement, the Construction Contract or otherwise.


                             ARTICLE 13 - CHANGES

13.1     All Work shall be in accordance with this Agreement, and it is the
         intent of the parties that Changes be avoided to the extent
         practicable.  To this end, the correction by CONTRACTOR (with OWNER's
         prior approval) of its [normal design or related errors and minor
         changes [What does this mean?]] made by CONTRACTOR in the course of
         the Work shall not be deemed to constitute a Change.

13.2     At any time during the course of the Work, OWNER may modify the Scope
         of Work as set forth in this Agreement, by written notice to
         CONTRACTOR.  Without limiting the generality of the foregoing, OWNER
         may make changes in drawings, designs and specifications, issue
         additional instructions, require additional work, or direct the
         omission of Work previously ordered.  When a Change is under
         consideration by OWNER, OWNER shall so notify CONTRACTOR.  OWNER may
         request a "scoping estimate" (one which requires no more than five
         manhours to prepare) before requesting a
    





                                       16
<PAGE>   167
   
         detailed cost estimate.  If OWNER wishes to consider the proposed
         Change after reviewing the scoping estimate, OWNER will request a
         detailed cost estimate.  CONTRACTOR shall then prepare and submit a
         detailed cost estimate (including, if deemed necessary by CONTRACTOR,
         revisions to the Target Date and to any of CONTRACTOR's guarantees
         which will result therefrom).  Once the parties mutually agree on the
         detailed cost estimate, they shall confirm their agreement in writing
         by means of a Change Order.  OWNER shall compensate CONTRACTOR for
         preparing all estimates made at OWNER's request.

13.3     If any of the events set forth below occur and CONTRACTOR determines
         that the result thereof is or will be a Change, CONTRACTOR shall
         promptly submit in writing to OWNER its proposed revision to the
         Contract Price together with the effect, if any, predicted by
         CONTRACTOR on the Target Date or CONTRACTOR's guarantees.  Once the
         parties mutually agree on such items, they shall promptly thereafter
         agree in writing upon a Change Order.  Such events are:

         (a)     a change in the basic design data or Site data (including
                 soils, feedstock, etc.) from that set forth in this Agreement;

         (b)     suspension of Work by OWNER [provisions governing suspension?];

         (c)     Force Majeure events preventing CONTRACTOR's performance
                 hereunder; provided that delays attributable to causes other
                 than Force Majeure events affecting Subcontractors and/or
                 Vendors directly shall not constitute Force Majeure;

         (d)     [VAT?] [?Any change in Trinidad taxes?]; or

         (e)     in connection with the Work, any act, or failure to act, on
                 the part of OWNER or any Affiliate of OWNER or any entity in
                 privity of contract with OWNER or any entity exclusively under
                 OWNER's direction or control.

13.4     CONTRACTOR shall not proceed with any Change until a Change Order has
         been signed by the parties.

13.5     Except to the extent agreed otherwise pursuant to a Change Order, the
         compensation payable to CONTRACTOR for preparing estimates pursuant to
         this Article 13, shall be determined in accordance with Annex D.


                               ARTICLE 14 - LIENS

14.1     CONTRACTOR shall immediately pay and discharge or shall provide
         security sufficient and satisfactory in itself to pay and discharge
         any obligation

         CONTRACTOR or any of its Subcontractors or Vendors may have, in
         respect of which any Encumbrance may be levied or is levied against
         the Work, the Construction Work, the Plant, the Facility,  the Site,
         or the Owner Indemnified Parties.  CONTRACTOR shall indemnify, defend
         and hold harmless the Owner Indemnified Parties from and against any
         such Encumbrance and any and all associated Losses.  If at any time
         OWNER shall receive notice or information of the recording of any such
         Encumbrance or any evidence of any such Encumbrance which, if valid,
         would constitute a legal charge upon property of OWNER, the Plant, the
         Facility or any part thereof, it shall forthwith communicate the
         receipt of such notice, information or evidence to CONTRACTOR.

14.2     If any such Encumbrance remains unsatisfied after the Date of
         Mechanical Completion, CONTRACTOR shall promptly refund to OWNER all
         amounts that OWNER may be compelled to pay in discharging any such
         Encumbrance.

                LICENSE, USE OF INFORMATION AND CONFIDENTIALITY

15.1     Subject to the terms and conditions of this Article 15, including
         without limitation payment in full of the license fee described in
         Section _______, CONTRACTOR grants to the Licensees the non-exclusive,
         non-transferable, perpetual and non-cancelable right and license to
         use and practice the Kellogg Advanced Ammonia Process in connection
         with the design, construction, start-up, testing, operation,
         maintenance, repair, and, if necessary, reconstruction of the Facility
         and the Plant (collectively, "Licensed Activities"), including,
         without limitation,the right to make and have made for use in
         connection with the Licensed Activities any apparatus therefor, and

15.2     All drawings, prints and specifications which are furnished to any
         Licensee by CONTRACTOR in connection with the Work shall be
         permanently retained by any Licensee only for use in monitoring
         CONTRACTOR's Work or Construction Work, in training the Licensee's
         employees and in performing any other Licensed Activities (including
         the replacement of parts).  Subject to the license and rights granted
         in Section 15.1, such drawings, prints and specifications shall at all
         times remain the property of CONTRACTOR.

15.3     OWNER undertakes to hold in confidence all know-how, drawings, manuals
         and data (collectively referred to as "Technical Information")

         know-how, drawings, manuals or data are [part of the KAAP process],
         and are identified by CONTRACTOR in writing, at or before their
         disclosure, to be confidential or proprietary.  OWNER agrees that it
         will not, without

         the written permission of CONTRACTOR,  use the Technical Information
         for any purpose except as provided in Section 15.2 or otherwise for
         any other Licensed Activity.

15.4     In the event OWNER retains the services of any third party in
         connection with any part of the Licensed Activities, and such third
         party has a need for any of the Technical Information, OWNER shall
         cause such third party to execute an agreement substantially identical

         responsible for enforcing the third party's adherence to the terms of
         such agreement.

15.5     [This may need to be expanded]  CONTRACTOR agrees to hold in

         operation and maintenance of the Facility, or otherwise, which
         information is identified by such Licensee in writing to be
         confidential or proprietary at or prior to its disclosure.  Said
         information shall remain the property of such Licensee, and CONTRACTOR
         shall not disclose such information to any third party or use such
         information for any purpose other than performing the Work.

15.6     The provisions of Sections 15.3 and 15.5 shall not apply to:
    

         (a)     any information (including Technical Information) which, at
                 the time of disclosure, the receiving party can show was in
                 the public domain;

         (b)     any information (including Technical Information) which, after
                 disclosure, becomes part of the public domain by publication
                 or otherwise, through no fault of the receiving party;

   
         (c)     any information (including Technical Information) which the
                 receiving party can show by supporting documentation was in
                 its possession at the time of disclosure to it by the
                 disclosing party and had not been acquired directly or
                 indirectly under the obligation of confidence to the
                 disclosing party;

         (d)     any information (including Technical Information) furnished to
                 the receiving party rightfully by a third party not under an
                 obligation of confidentiality to the disclosing party,
                 provided again that the receiving party is in compliance with
                 any restrictions on disclosure or limitation of use imposed by
                 such third party;

         (e)     any information (including Technical Information)
                 independently developed by employees or consultants of the
                 recipients or its Affiliates who have not had access to such
                 information; or

         (f)     any information (including Technical Information) required by
                 law, rule, regulation or bona fide legal process to be
                 disclosed, provided that the receiving party making such
                 disclosure shall take all reasonable steps to restrict, and
    





                                       19

                 maintain to the extent possible the confidentiality of, such
                 disclosure, and shall provide reasonable notice to the other
                 party whose information is involved in order that such other
                 party may take reasonable steps to oppose the requirement of
                 disclosure.

         For the purpose of this Section 15.6, any disclosure of such
         information which is specific to the operating or design conditions of
         the Plant shall not be deemed to be within the foregoing exceptions
         merely because it is contained within the scope of a broad disclosure.

15.7     Notwithstanding anything herein to the contrary, each Licensee shall
         have the right to disclose (subject to Section 15.4) the Kellogg
         Advanced Ammonia Process or Technical Information to third parties for
         any valid effectuation by the Licensees of the Licensed Activities.

15.8     Notwithstanding the expiration, suspension or termination of this
         Agreement, the Licensees and/or (subject to Section 15.4) any third
         party retained or to be retained by any Licensee, shall be entitled,
         for the duration of the time period in which any Licensee or any such
         third party shall be conducting any Licensed Activity, to the benefits
         and use of, and rights and interest in, the Kellogg Advanced Ammonia
         Process and the Technical Information, as provided herein.

15.9     Upon the expiration or termination of this Agreement, CONTRACTOR
         shall, promptly upon demand, provide the Licensees for the duration of
         the time period in which any Licensee, or any third party retained or
         to be retained by any Licensee described in Section 15.8 above, shall
         be conducting any Licensed Activity, the use of any know-how,
         drawings, manuals and data (including, without limitation, KAAP
         updates and revisions) necessary or useful for the Licensed
         Activities, to the extent that such know-how, drawings, manuals, data,
         etc. are not in the possession of the Licensees.

         owner, as the case may be, with respect to the Kellogg Advanced
         Ammonia Process or Technical Information.

16.2     Subject to the provisions of this Article 16, CONTRACTOR shall, at its
         sole cost and expense, indemnify, defend and hold the Licensees and
         Owner Indemnified Parties harmless in respect of any and all Losses
         incurred in connection with any claim, suit or proceeding based on any
         claim that the Work (or Construction Work) as incorporated into the
         Plant, the Facility or any part of any thereof, or the Kellogg
         Advanced Ammonia Process, or any part thereof, or any Technical
         Information, or any part thereof, constitutes an infringement or
         violation of any patent or other intellectual property right of a
         third party, including, without limitation, infringement or violation
         of any copyright, trademark or trade secret, and infringement of any
         patent issued in the United States or the Republic of Trinidad and
         Tobago.

16.3     OWNER agrees to notify CONTRACTOR promptly in writing of any notice or
         claim of infringement and/or violation as described in Section 16.2
         above which is received by or brought against OWNER.

16.4     In connection with any claim described in Section 16.2 above,
         CONTRACTOR reserves the right to acquire for the Licensees, at
         CONTRACTOR's sole cost and expense, immunity from suit and license to
         use the offending technology, which are acceptable to the Licensees.
         CONTRACTOR also reserves the right, in connection with such claim, of
         making such alterations of the Facility, at CONTRACTOR's sole cost and
         expense, as may be required to eliminate the alleged infringement;
         provided such alteration is acceptable to the Licensees and does not
         prevent the Facility from being capable of normal operation, reduce
         the capacity of the Facility, interfere with the Performance
         Guarantees or performance levels, or cause a default by the Licensees
         under any contract or other obligation.

16.5     Neither CONTRACTOR nor OWNER shall settle or compromise any suit or
         action described in Section 16.2 above without the written consent of
         the other.

16.6     Except to the extent that substantial deviation by the Licensees from
         information furnished by CONTRACTOR is the sole cause for a claim of
         infringement, CONTRACTOR shall defend, indemnify and hold the
         Licensees and Owner Indemnified Parties harmless from and against any
         and all Losses that may be assessed in or become payable under any
         decree or judgment of any court, or under any arbitral  decree or
         other order, including costs and expert and professional fees, with
         respect to any suit or action described in Section 16.2 above.

16.7     OWNER shall defend, indemnify and hold CONTRACTOR harmless from and
         against any claim that any technology or know-how supplied to
         CONTRACTOR by OWNER wrongly incorporates proprietary technical data or
         infringes letters patent issued to, or otherwise infringes any other
         intellectual property rights of, a third party.

16.8     The provisions of Sections 16.2, 16.6 and 16.7 shall not apply to any
         Vendor's or Subcontractor's wrongful use of proprietary technical data
         or infringement of patents (unless caused by such Vendor's or
         Subcontractor's compliance with specific design requirements imposed
         by CONTRACTOR).  In the event of any such wrongful use or
         infringement, CONTRACTOR and OWNER shall rely on the provisions for
         indemnity against infringement and other terms contained in applicable
         purchase order, subcontract or other agreement with the Vendor or
         Subcontractor; provided, however, that to the extent (i) there exists
         any excess liability not covered by and discharged pursuant to the
         provisions contained in applicable purchase order, subcontract or
         other agreements with the Vendor or Subcontractor, and/or (ii) there
         are no such provisions, the CONTRACTOR shall bear sole and complete
         responsibility and liability for, and shall indemnify the Owner
         Indemnified Parties with respect to, any such wrongful use or
         infringement.


                  ARTICLE 17 - SERVICES, AND OTHER ITEMS TO BE

                 OWNER's established accounting procedure for the guidance of
                 CONTRACTOR in preparing final cost distributions; and

         (d)     promptly pay when due all duties, fees and charges imposed by
                 the Republic of Trinidad and Tobago relative to the import of

17.2     OWNER shall appoint a representative to act on OWNER's behalf in the
         administration and performance of this Agreement [as provided in the
         Coordination Procedures?].  Such representative will be available to
         CONTRACTOR at all reasonable times.

17.3     After the Facility has commenced commercial operation, upon reasonable
         advance notice from CONTRACTOR and subject to the approval of OWNER in
         each instance, representatives of CONTRACTOR and CONTRACTOR's

         reasonable number of personnel during normal business hours, and shall
         be scheduled at times mutually agreed with OWNER to assure minimal
         interference with OWNER's Facility operations.  CONTRACTOR shall cause

         incorporation into the Work or Construction Work) until the Date of
         Mechanical Completion.  CONTRACTOR assumes all risk of any loss or
         damage thereto until the Date of Mechanical Completion.  For the
         purpose of this Agreement, those temporary facilities erected by
         CONTRACTOR or the Constructor at the Site which are affixed to the
         Site so as to be nonportable (such as job-built buildings, roads,
         security fences, electrical power polelines, underground septic tanks,
         deadmen, and piping for construction utilities) shall be deemed to be
         Construction Work in progress.  CONTRACTOR hereby releases and
         discharges and shall defend, indemnify and hold harmless the Owner
         Indemnified Parties from and against any and all Losses arising from
         or related to any loss or damage as described in the first sentence of
         this Section 18.1, irrespective of any negligence, including sole or
         concurrent negligence, on the part of any Owner Indemnified Party.

18.2     With respect to the machinery, tools, equipment, materials and other
         property not intended to become a permanent part of the Facility and
         which are supplied or used by CONTRACTOR, Constructor, or any
         Subcontractor or Vendor thereof, CONTRACTOR assumes all risk of any
         loss or damage thereto.  CONTRACTOR hereby releases and discharges and
         shall defend, indemnify and hold harmless the Owner Indemnified
         Parties from and against any and all Losses arising from or related to
         any such loss or damage, irrespective of any negligence, including
         sole or concurrent negligence, on the part of any Owner Indemnified
         Party.

18.3     With respect to any and all claims of loss or damage to any property
         owned, leased, operated, used or controlled by any Owner Indemnified
         Party other than the Facility at or within
         _____________________________________ from the Site and any property
         owned, leased, operated, used or controlled by any Affiliate of
         Arcadian Trinidad Limited, and with respect to all occurrences and
         circumstances prior to the Date of Mechanical Completion, CONTRACTOR
         hereby releases and discharges and shall defend, indemnify and hold
         harmless the Owner Indemnified Parties from and against any and all
         Losses arising from or related to any such claims, occurrences or
         circumstances which are alleged to arise from any act or omission on

         negligence, including sole or concurrent negligence, on the part of
         any Owner Indemnified Party; provided, however, that the aggregate
         amount of liability assumed by CONTRACTOR under this sentence shall in
         no event exceed ____________ _________________________
         (US$_________________).  [The following may be inconsistent with
         Arcadian's proposal that Kellogg keep completed operations insurance
         in place for 3 years after acceptance.] For all other claims regarding
         the property described in the preceding sentence of this Section
         [15.3] and to the extent such claims are not assumed by CONTRACTOR as
         aforesaid, OWNER hereby releases CONTRACTOR from, and agrees to
         defend, indemnify and hold CONTRACTOR harmless against all such
         claims.

18.4      [The following may be inconsistent with Arcadian's proposal that
         Kellogg keep completed operations insurance in place for 3 years after
         acceptance.] With respect to the Facility and for all occurrences on
         or after the Date of Mechanical Completion, OWNER hereby assumes the
         risk of all loss or damage thereto and releases CONTRACTOR from, and
         agrees to defend, indemnify and hold CONTRACTOR harmless against all
         Losses arising from or directly or indirectly related to the Work,
         except to the extent attributable to any act or omission of
         CONTRACTOR, Constructor, or any Subcontractor or Vendor, including,
         without limitation, any breach of any warranty or other provision of
         this Agreement or the Construction Contract.

18.5     CONTRACTOR hereby releases and discharges and shall indemnify, defend
         and hold harmless the Owner Indemnified Parties from and against any
         and all Losses arising from or related to any injury to or death of
         any of CONTRACTOR's, Constructor's, or any Subcontractor or Vendor's
         employees, agents, officers, representatives, licensees, or invitees
         in connection with or incidental to the Work or the Construction Work,
         irrespective of any negligence, including sole or concurrent
         negligence, on the part of any Owner Indemnified Party.

18.6     With respect to products, materials, or substances (including, without
         limitation, any pollutant, contaminant or hazardous or toxic
         substance, material or waste) introduced to the Site by CONTRACTOR,
         Constructor, or any Subcontractor or Vendor, CONTRACTOR releases and
         discharges and shall defend, indemnify and hold harmless the Owner
         Indemnified Parties from and against any and all Losses arising from
         or related to any such introduction, including, without limitation,
         any failure to properly handle, store or dispose of any such products,
         materials, substances, etc., irrespective of any negligence, including
         sole or concurrent negligence, on the part of any Owner Indemnified
         Party.  With respect to environmental contamination (if any) due to
         the presence of any pollutant, contaminant or hazardous or toxic
         substance, material or waste at the Site, prior to the commencement of
         Work, OWNER hereby releases and discharges and shall defend, indemnify
         and hold harmless the Contractor Indemnified Parties from and against
         any and all Losses arising from or related to such environmental
         contamination, irrespective of any negligence, including sole or
         concurrent negligence, on the part of any Contractor Indemnified
         Party.

18.7     With respect to any and all Losses which arise from or relate to
         occurrences or circumstances prior to the Date of Mechanical
         Completion [expiration of completed operations coverage?] and which
         are not provided for in Sections [18.1-18.6] above, CONTRACTOR
         releases and discharges and shall defend, indemnify and hold harmless
         the Owner Indemnified Parties therefrom, if such Losses are alleged to
         arise from any act or omission on the part of OWNER, CONTRACTOR, the
         Constructor, or any Subcontractor or Vendor, and irrespective of any
         negligence, including sole or concurrent negligence, on the part of
         any Owner Indemnified Party.  [Completed Operations proposal
         consistency]  With respect to all such claims, etc. as described in
         the preceding sentence of this Section 18.7, and which arise from
         occurrences on or after Mechanical Completion,  OWNER shall defend,
         indemnify and hold CONTRACTOR harmless therefrom if such claims, etc.
         arise from any act or omission on the part of OWNER or CONTRACTOR and
         irrespective of any negligence, including sole or concurrent
         negligence, on the part of CONTRACTOR.

18.8     The party making a claim for indemnity under this Article 18
         ("Indemnified Party") shall promptly notify the party obligated to
         indemnify ("Indemnifying Party") of the assertion or commencement of
         any claim, demand, investigation, action, suit or other legal
         proceeding in respect of which indemnity is or may be sought
         hereunder; provided, however, that this notice requirement shall not
         apply to any claim, demand, investigation, action, suit or other legal
         proceeding in which the parties are adversaries.  The failure by the
         Indemnified Party to so notify the Indemnifying Party shall not

         settlement of any third-party claim, demand, investigation, action,
         suit or other legal proceeding (collectively "Third-Party Claims")
         with counsel reasonably satisfactory to the Indemnified Party;
         provided, however, that the Indemnifying Party shall not settle or
         compromise any Third-Party Claim without the Indemnified Party's prior
         written consent thereto.  Notwithstanding the foregoing, (1) the
         Indemnified Party shall have the right, at its option and expense, to

         shall have the right, but not the obligation, to undertake the defense
         or settlement of such Third-Party Claim for the account of and at the
         risk of the Indemnifying Party, and (b) the Indemnifying Party shall
         be bound by any defense or settlement that the Indemnified Party may
         make as to such Third-Party Claim.  The Indemnified Party shall be
         entitled to join the Indemnifying Party in any Third-Party Claim for
         the purpose of enforcing any right of indemnity hereunder.  The
         Indemnified Party shall cooperate with the Indemnifying Party in the
         defense or settlement of any Third-Party Claim and, at the expense of

         status as an Additional Insured, or OWNER's exercise of rights under

         ________ [limit w/e/t adjacent Facilities] above  shall not limit, and

         policy with an insurance policy as called for in this Article 18; and

         if CONTRACTOR does not comply with this covenant, OWNER may obtain the
         replacement insurance policy and recover all premiums paid therefor
         from CONTRACTOR.  CONTRACTOR shall deliver to OWNER evidence of all
         such insurance in the form of an insurance certificate(s); CONTRACTOR
         shall provide such additional insurance certificates as OWNER may
         reasonably request from time to time.

18.14    If CONTRACTOR subcontracts any part of the Work, the insurance
         provisions of each subcontract shall be in accordance with
         CONTRACTOR's usual practice. CONTRACTOR shall be responsible to ensure
         that its Subcontractors maintain insurance as required in the
         subcontracts during the course of Subcontractor's operations in

         Insurance for land transportation on all Work items with a declared
         replacement value in excess of US$1,000,000.  CONTRACTOR will provide
         a list of cargo for each ocean freight shipment noting each item's

          hereunder, it is agreed that upon giving notice and full particulars
          of such force majeure event by telephone (confirmed in writing),
          facsimile transmission or in writing to the other party, as soon as
          possible after the occurrence of the cause relied upon, then the
          obligations of OWNER or CONTRACTOR, so far as they are affected by
          such force majeure event, shall be suspended during the continuance
          of any inability so caused, but for no longer period, and such cause
          so far as possible shall be remedied with all reasonable dispatch.

          unable to prevent or overcome.

                weeks from the effective date of the notice of termination) for

          (c)   all termination and cancellation charges incurred in
                terminating commitments made to Subcontractors, Vendors [and

                costs for the travel, living and related costs incurred by
                CONTRACTOR for relocating and reassigning CONTRACTOR's
                personnel located in Trinidad and Tobago at the time of the

          hereof and such breach shall not be corrected within ten (10) days
          after written notice from OWNER to CONTRACTOR (or, if such breach is
          not correctable within ten (10) days, then within a reasonable time

          under substantially similar terms and conditions as specified herein
          in any manner OWNER deems expedient, provided that OWNER shall be
          required to mitigate its damages in so completing the Work.  In the
          event the reasonable and necessary costs incurred by OWNER to
          complete the Work exceed the Contract Price, CONTRACTOR shall be
          required to reimburse OWNER for such excess.

                           ARTICLE 27 - MISCELLANEOUS

27.1      Entire Agreement.  This Agreement (including the attached annexes)
          constitutes the full understanding of the parties, a complete
          allocation of risks between them, and a complete and exclusive
          statement of the terms and conditions of their agreement relating to
          the subject matter hereof and supersedes any and all prior
          negotiations, understandings and agreements, whether written or oral,
          between the parties with respect thereto, including, without
          limitation, any and all interim arrangements and agreements.  Except
          as otherwise specifically provided in this Agreement, no term,
          condition, usage of trade, course of dealing or performance,
          understanding or agreement purporting to modify, vary, explain or
          supplement the provisions of this Agreement shall be effective or
          binding on the parties, unless the same hereafter is effected in
          accordance with Section 27.2.

27.2      Amendments.  This Agreement may not be altered, modified, amended or
          changed (other than any waiver of any provision hereof, which shall
          be effective only if made in accordance with Section 27.3) in any
          manner, except by a written agreement executed and delivered by all
          parties.  Without limiting the generality of the foregoing, this
          Agreement shall not be altered, modified, amended or changed by any
          terms or provisions of purchase orders, invoices or other documents
          issued, delivered, and/or executed by or to CONTRACTOR or OWNER in
          connection with the Work or otherwise.

27.3      Waivers.  No waiver by any party of any breach of the covenants set
          forth herein or any claim, right or remedy provided for hereunder and
          no course of dealing shall be deemed a waiver of the same or any
          other breach, claim, right or remedy, unless such waiver is in
          writing and is signed by the party sought to be bound.  The failure
          of a party to assert or exercise any claim, right or remedy shall not
          be deemed a waiver of such claim, right or remedy in the future.  Any
          failure by either OWNER or CONTRACTOR at any time or from time to
          time to enforce or insist upon the strict keeping and/or performance
          of any of the terms or conditions of this Agreement, shall not
          constitute a waiver of such terms or conditions, and shall not affect
          or impair such terms or conditions in any way, or the rights of OWNER
          or CONTRACTOR at any time to avail itself of such remedies as it may
          have for any breach or breaches of such terms or conditions.

27.4      Modification and Severability.  If an arbitration tribunal or court
          of competent jurisdiction declares that any provision of this
          Agreement is illegal, invalid or unenforceable, then such provision
          shall be modified automatically to the extent necessary to make such
          provision fully legal, valid and enforceable.  If such arbitration
    





                                       34
<PAGE>   185
   
          tribunal or court does not modify any such provision as contemplated
          herein, but instead declares it to be wholly illegal, invalid or
          unenforceable, then such provision shall be severed from this
          Agreement, and this Agreement, and the rights and obligations of the
          parties hereto, shall be construed as if this Agreement did not
          contain such severed provision, and this Agreement otherwise shall
          remain in full force and effect.

27.5      Enforceability.  This Agreement shall be enforceable by and against

          maximum period permitted by applicable law (subject to the duration
          limitations set forth in Article _____), the termination, suspension
          or expiration of the Work (or any portion thereof) or this Agreement

          [indemnity, license, patent, confidentiality], and the parties'
          respective obligations, rights and remedies thereunder, shall survive
          the termination, suspension or expiration of the Work (or any portion
          thereof) or this Agreement (or any portion thereof) for the maximum
          period permitted by applicable law.

27.7      Conflicts.  In the event there are conflicts between the provisions
          set forth in the body of this Agreement and those set forth in
          annexes hereto, the provisions set forth in the body of this
          Agreement shall control.

          covenant contained in this Agreement, the other party shall be
          entitled to equitable relief (including, without limitation, specific

          Any party's full or partial exercise of any remedy shall not preclude
          any subsequent exercise by said party of the same or any other
          remedy.

27.11     Cumulative Nature.  The respective rights and remedies of the parties
          under this Agreement shall be cumulative of, in addition to, and not

              to inspection by the Authority its servants and agents or jointly
              by the Authority and the Company their servants, agents and
              others duly authorized by them in their behalf who shall also be

              The Company may request the Authority to check, test and
              calibrate the said meters and/or other instruments at such other
              reasonable times as the Company considers necessary provided

                     test on which a reading of the index of the meters and/or
                     instruments was taken by the Authority unless it or they

                     later date;

              (ii)   If a meter or other instrument is found to be out of order
                     or if it or they be removed for repairs, adjustments or
                     alterations the fact shall be noted by the Authority and a
                     written memorandum thereof shall be served on the Company.

                                   EXHIBIT N


                         DESCRIPTION OF OSHA LITIGATION


                 In January 1993, OSHA issued citations to Agent and proposed a
total civil penalty of $5.1 million as a result of the failure of the urea unit
at the Lake Charles plant in 1992.  In December 1993, the judge in the ensuing
administrative law proceeding reduced the proposed penalty for the principal
citation from $4.4 million to $50,000 in granting Agent's motion for partial
summary judgment and severance.  OSHA has appealed this decision to the
Occupational Safety and Health Review Commission ("Review Commission"), and on
September 15, 1995, the Review Commission affirmed the judge's decision.  The
Review Commission also remanded the case to the judge and ordered the
consolidation of the previously severed citations in order to allow OSHA to
seek the judge's permission to amend the citation.  OSHA chose not to seek an
amendment, and the judge again severed the citations.  OSHA has again appealed
the decision reducing the penalty to the Review Commission as a procedural
prerequisite to seeking judicial review of the decision in the United States
Court of Appeals.  In the meantime, the trial on the merits of the underlying
citation has been concluded, but a decision is not expected for several months.

                 In October 1994, Agent paid $.4 million to OSHA to settle the
remaining citations.  Agent did not admit to violating any law, regulation or
safety standard and entered into the partial settlement solely to avoid the
substantial cost and burden of litigating these issues.  Agent maintains that
it operated the Lake Charles plant in accordance with applicable health and
safety regulations and industry standards, and continues to believe
emphatically that OSHA's claims are without merit.

                 While management and legal counsel believe that any civil
penalty ultimately paid by Agent will be substantially less than the remaining
$4.4 million penalty proposed by OSHA, they cannot predict with certainty the
outcome of this proceeding.

                 Agent received a large number of claims for personal injury
and property damage as a result of the Lake Charles incident.  Most of the
claims were settled through a claims adjuster retained by Agent and its
liability insurance carriers.  A number of suits arising from the incident also
were filed against Agent.  There are currently 11 suits pending in the United
States District Court for the Western District of Louisiana, Lake Charles
Division, which have been consolidated for joint administration, and 13 cases
(including one suit that has been certified as a class action) pending in the
14th Judicial District Court of Calcasieu Parish, Louisiana, which also have
been consolidated for joint administration.  The plaintiffs in these suits
generally are seeking damages for alleged physical, mental and emotional
suffering and other personal injuries, and/or property damage, lost earnings
and other economic losses as a result of the failure.  Most of the suits also
include claims for punitive damages.  All but three of the suits are being
defended by Agent's liability insurance carriers on its behalf, and the damages
alleged in such suits are believed to be within the maximum coverage limit of
the liability insurance.  The remaining three actions, in which the plaintiffs
are substantially identical and assert substantially the same claims of
economic and other injuries, are being defended by Agent

and may not be covered by its liability insurance.  Agent believes that many of
the unsettled claims and the suits are frivolous and/or insubstantial and is
vigorously defending against the same.

                  (a) Subject to the terms and conditions hereof, the Lessor
shall lease to the Lessee, and the Lessee may lease from the Lessor pursuant to
this Lease, any Property or Equipment of the type listed on Exhibit A hereto,
when and as the Lessee has need of such Property or Equipment; provided, that:

             (i)  such Property or Equipment is available for purchase;

            (ii)  except with respect to any Parcel of Property acquired and
                  built pursuant to the Agreement for Lease, the Lessor has
                  approved the purchase order or acquisition with respect to
                  such Equipment or the acquisition with respect to such

           (iii)  at the time any such Property or Equipment is to be ordered or
                  leased hereunder there exists no Event of Default or Potential

            (iv)  with respect to any Parcel of Property or Unit of Equipment
                  acquired and built pursuant to the Agreement for Lease, the
                  conditions for the Lessee to execute an AFL Unit Leasing

                  Equipment and (B) the aggregate Acquisition Cost of all other
                  Property or Equipment leased hereunder would not, at the time
                  any such Property or Equipment is to be leased hereunder,
                  exceed such amount as the Lessor and the Lessee may from time

the Lessee and has been accepted for lease hereunder by the Lessee as of the

Equipment, other than a Unit of Equipment appropriately included in an AFL Unit
Leasing Record, to the Lessee under this Lease shall be evidenced by a Unit
Leasing Record. The Lessee shall prepare and execute a Unit Leasing Record with
respect to each such Parcel of Property or Unit of Equipment (which Unit Leasing
Record may relate to more than one Unit of Equipment) and deliver it promptly to
the Lessor. Contemporaneously with the payment required by paragraph (b) of
Section 5 hereof, the Lessor shall execute the acceptance of such Unit Leasing
Record and promptly return one copy of such Unit Leasing Record to the Lessee.

                  (d) The Lessee shall prepare each Unit Leasing Record pursuant
to the procedures provided by the Lessor. Each Unit Leasing Record and AFL Unit
Leasing Record shall give a full description of the Parcel or Parcels of
Property or Unit or Units of Equipment covered thereby, the Acquisition Cost of
each such Parcel or Unit, the Initial Term and Renewal Term for each such Parcel
or Unit, its location and such other details as the Lessor and the Lessee may
from time to time agree.

                  (e) Execution by the Lessee of a Unit Leasing Record or AFL
Unit Leasing Record shall constitute (i) acknowledgment by the Lessee that the
Property or Equipment specified in such Unit Leasing Record or AFL Unit Leasing
Record has been delivered to the Lessee in good condition and has been accepted

Equipment acquired and built pursuant to the Agreement for Lease, within six (6)
months of the Effective Date of such Parcel or Unit, the Lessee may deliver to
the Lessor a Certificate of Increased Cost (as defined in

actual amount expended by the Lessee for items included in the Unit Budget (as
defined in the Agreement for Lease) with respect to such Parcel or Unit. If,
based upon such Certificate of Increased Cost, a Completion Advance (as defined
in the Agreement for Lease) is to be made, the Lessor shall execute within five
(5) days of receipt of such Certificate of Increased Cost from the Lessee a
revised AFL Unit Leasing Record to amend the Acquisition Cost for such Parcel or
Unit to reflect the increase in the Acquisition Cost. In the event the Lessee
shall receive a Completion Advance with respect to the Ammonia Project, the
Lessee shall, on the Business Day immediately succeeding such Completion
Advance, deposit or cause to be deposited into the Cash Reserve Account an
amount equal to 40% of such Completion Advance, to be held by the CRA Bank
pursuant to the CRA Agreement.

                  SECTION 4. OPERATING LEASE.

                  The Lessor and the Lessee hereby declare that it is their
mutual intent that for accounting and regulatory purposes this Lease be treated
as an operating lease and not an instrument or evidence of indebtedness, and
that the relationship between the Lessor and the Lessee under this Lease shall
be that of lessor and lessee only. Title to and ownership of any Property or
Equipment shall at all times remain in the Lessor and at no time become vested
in the Lessee except in accordance with an express provision of this Lease. The
Lessee does not hereby acquire any right, equity, title or interest in or to any
Property or Equipment except pursuant to the terms hereof.

                  SECTION 5. DELIVERY.

                  (a) The Lessee shall acquire or order and accept Property or
Equipment, other than Property and Equipment acquired and built pursuant to the

than Property acquired and built pursuant to the Agreement for Lease, or a Unit
of Equipment, other than a Unit of Equipment acquired and built pursuant to the
Agreement for Lease, by the Lessee and the Lessor and receipt by the Lessor of
(i) the vendor's invoice or invoices for such Unit of Equipment and a contract
of sale and deed with respect to each Parcel of Property, (ii) invoices or other
evidence satisfactory to the Lessor for any amounts included in the Acquisition
Cost of such Parcel or Unit payable to parties other than the vendor, (iii)
invoices or other evidence satisfactory to the Lessor (including an appraisal
with respect to a Parcel of Property or Unit of Equipment) for any amounts
included in the Acquisition Cost of such Parcel or Unit that have been paid to
the vendor or other parties by the Lessee and for any costs included in the
Acquisition Cost of such Parcel or Unit incurred by the Lessee, (iv) a Unit
Leasing Record with respect to such Parcel or Unit duly prepared and executed by
the Lessee and (v) such other documentation as the Lessor may reasonably
require, the Lessor shall (A) pay to such vendor the amount of the vendor's
invoice or invoices and/or contract of sale for such Parcel or Unit except to
the extent previously paid by the Lessee, (B) pay to such other parties such
amounts payable, except to the extent previously paid by the Lessee and (C)
reimburse or pay to the Lessee for such amounts paid to the vendor or other
parties by the Lessee, for such costs incurred by the Lessee and, if agreed
between the Lessor and the Lessee, for the appraised value of the Property or
Equipment; provided, however, that in no event shall the sum of all payments
made pursuant to clauses (A), (B) and (C) above exceed the Acquisition Cost of
such Property or Equipment.

HEREAFTER MAY BE CONFERRED UPON IT, BY STATUTE OR OTHERWISE, TO TERMINATE,
CANCEL, QUIT, RESCIND OR SURRENDER THIS LEASE EXCEPT IN ACCORDANCE WITH THE
EXPRESS TERMS HEREOF. Each payment of Basic Rent, Additional Rent and any other
amount due hereunder made by the Lessee shall be final, and the Lessee, without
waiving any other remedies it may have, will not seek or have any right to
recover all or any part of such payment from the Lessor or any Assignee for any
reason whatsoever. The making of payments under this Lease by the Lessee
(including without limitation payments pursuant to Section 11 hereof) shall not
be deemed to be a waiver of any claim or claims that the Lessee may assert in a
separate action against the Lessor or any other Person. The Lessor agrees to
repay the Lessee amounts paid to the Lessor to the extent such payments were in
error and are not required by any of the terms and provisions of this Lease.

                  (e) Notwithstanding any other provision contained in this
Lease, it is specifically understood and agreed that neither the Lessor nor any
Assignee nor any Affiliate of either, nor anyone acting on behalf of any of them
makes any warranties or representations, nor, except as set forth in Section 22
of this Lease, has the Lessor or any Assignee or any Affiliate of either, or
anyone acting on behalf of any of them made any covenants or undertakings, as to
the accounting treatment to be accorded the Lessee or as to the U.S. Federal or
any state income or any other tax consequences, if any, to the Lessee as a
result of or by virtue of the transactions contemplated by this Lease.

                  SECTION 6. INITIAL TERM; RENEWAL TERM.

                  (a) The "Initial Term" with respect to any Parcel of Property
or Unit of Equipment leased hereunder shall commence on the Effective Date set
forth in the Unit Leasing Record or the AFL Unit Leasing Record for such Parcel
of Property or Unit of Equipment and shall continue for the period agreed in
writing between the Lessee and the Lessor, unless terminated earlier pursuant to
the provisions of this Lease. The Initial Term applicable to the Ammonia Project
shall be the period from the Effective Date therefor until the seventh
anniversary of the date of this Lease.

                  (b) In the event this Lease is renewed pursuant to the terms
of Section 12 hereof, the Renewal Term with respect to any Parcel of Property or
Unit of Equipment shall commence on the first day of the calendar month
following the last day of the Initial Term of such Parcel or Unit and shall
continue for sixty (60) calendar months, unless terminated earlier pursuant to
the provisions of this Lease.

                  (c) With respect to each Unit of Equipment or Parcel of
Property, it is understood and agreed that the Initial Term of each Parcel of
Property or Unit of Equipment shall in no event exceed 75% of its economic
useful life remaining after the Effective Date for such Parcel or Unit.

                  (d) Notwithstanding anything contained in this Section 6, the
provisions of Sections 10 and 11 hereof and paragraph (a) of Section 15 hereof
shall apply with respect to any Property or Equipment from the time such
Property or Equipment is acquired by the Lessor, and from the date hereof as to
all property and equipment acquired, constructed, assembled or improved in
connection with the Ammonia Project.

                  SECTION 7. RENT AND OTHER PAYMENTS.

                  (a) The Lessee hereby agrees to pay the Lessor on each Basic
Rent Payment Date, the amount of Basic Rent due and payable on such Basic Rent
Payment Date.

                  (b) The Lessor shall provide notice to the Lessee on the
fourth (4th) day prior to each Basic Rent Payment Date of the amount of Basic
Rent due and payable from the Lessee to the Lessor on such Basic Rent Payment
Date (the "Lease Rate Date"). Subject to paragraph (e) of Section 7 hereof, the
Lessor's determination of Basic Rent shall be conclusive and binding absent
manifest error. At least two (2) Business Days prior to each Basic Rent Payment
Date the Lessor shall furnish the Lessee with a summary of the calculations of
Basic Rent payable on such Basic Rent Payment Date, which calculations shall be
consistent with the Minimum Lease Payment Calculations attached as Exhibit F
hereto.

                  (c) Without prejudice to the full exercise by the Lessor of
its rights under Sections 18 and 19 hereof, the Lessee shall pay to the Lessor
from time to time, on the Lessor's written demand, as additional rent
("Additional Rent") (i) amounts required to reimburse the Lessor for its
obligations, costs and expenses (not previously included in Basic Rent) incurred
in leasing the Property or Equipment (including, without limitation, all
obligations of the Lessor under or in respect of any interest rate swap, cap,
collar or other financial hedging arrangement and any amounts payable by the
Lessor under any such arrangement to reduce the notional amount thereof by the
amount of any prepayment of any borrowing to which such interest rate swap, cap,
collar or other financial hedging arrangement relates), and (ii) to the extent
legally enforceable, an amount computed by multiplying (A) all sums not paid by
the Lessee to the Lessor as provided in this Lease on or before the date such
payments are due, by (B) the decimal equivalent of the percentage referred to in
paragraph (a)(iii) of the definition of "Basic Rent" used in the calculation of
the most recent Basic Rent amount, and by (C) a fraction having a numerator
equal to the number of days in the period from but excluding such due date to
and including the date of payment thereof and a denominator of 365, or in a leap
year, 366. The Lessee shall also pay to the Lessor on the Lessor's written
demand an amount equal to any expenses (including the reasonable fees and
disbursements of counsel) incurred by the Lessor in collecting such unpaid sums.
Prior to the payment of any Additional Rent, the Lessor shall supply to the
Lessee a statement which describes the obligations, costs and expenses incurred,
and, if appropriate, a calculation of the amount of such Additional Rent. Such
statement shall be conclusive and binding absent manifest error.

                  (d) Basic Rent and Additional Rent and any other amount
payable by the Lessee to the Lessor shall be paid such that immediately
available funds in the full amount due are available on the date due, to the
account of the Lessor at such bank, or to such account of such other Person at
such bank, or otherwise as the Lessor may from time to time designate.

                  (e) During the Lease Term of any Parcel of Property or Unit of
Equipment, the Lessor shall calculate, on or before each Lease Rate Date (except
the first Lease Rate Date hereunder), the difference, if any, between (i) the
Basic Rent paid by the Lessee for the previous calendar month and (ii) an amount
equal to what the Basic Rent would have been for such calendar month had the
Basic Rent been calculated using the weighted average percentage cost per annum
of the borrowings outstanding at any time (as specified in subparagraph (a)(iii)
of the definition of Basic Rent) during the entirety of the previous calendar
month; provided, that with respect to the Basic Rent for the last month of the
Lease Term, such calculation shall occur on the

last day of the Lease Term. On each Lease Rate Date (except the first Lease Rate
Date hereunder) and on the last day of the Lease Term, the Lessor shall furnish
to the Lessee a calculation of the difference between the amounts determined
under clause (i) above and the correlating amounts determined under clause (ii)
above (the "Reconciliation Amount") for the previous calendar month. The Lessor
and the Lessee agree that if the Reconciliation Amount is a positive number,
then such amount shall be credited against the amount of Basic Rent that the
Lessee is required to pay on the next Basic Rent Payment Date (or Basic Rent
Payment Dates, if such amount shall exceed the amount of Basic Rent payable in
the next succeeding month), and if the Reconciliation Amount is a negative
number, then such amount shall be payable by the Lessee on the next Basic Rent
Payment Date in addition to the amount of Basic Rent due and payable on such
Basic Rent Payment Date, except that with respect to the Reconciliation Amount
computed on the last day of the Lease Term, such amount shall be paid by the
Lessor to the Lessee (in the case of a positive number) or by the Lessee to the
Lessor (in the case of a negative number) on the last day of the Lease Term. Any
notices required by this paragraph (e) which are furnished to the Lessee by the
Lessor shall be conclusive, absent manifest error, as to the contents thereof.

                  SECTION 8. RESTRICTED USE; COMPLIANCE WITH LAWS.

                  (a) So long as no Event of Default shall have occurred and be
continuing, the Lessee may use the Property or Equipment in the course of its
business for any lawful purpose. Without limitation of any of its other
obligations hereunder or under any other Operative Document, the Lessee agrees
that the Lessee will not do or permit any act or thing which could reasonably be
expected to materially impair the value or utility of any Property or Equipment.

                  (b) The Lessee shall promptly and duly execute, deliver, file
and record, at the Lessee's expense, all such documents, statements, filings and
registrations, and take such further action as the Lessor or any Assignee shall
from time to time reasonably request and shall install such signs or other
markings as shall be required by any applicable Legal Requirement in order to
establish, perfect and maintain the Lessor's or any Assignee's title to and
interest in the Property or Equipment and any Assignee's interest in this Lease
or any Property or Equipment as against the Lessee or any third party in any
applicable jurisdiction. The Lessor agrees that it will not change the location
of the Ammonia Project. At the reasonable request of the Lessor, but, so long as
no Event of Default has occurred and is continuing no more than once each year,
the Lessee shall advise the Lessor in writing where all Equipment leased
hereunder as of such date is principally located.

                  (c) The Lessee shall use every commercially reasonable
precaution to prevent loss or damage to Property or Equipment and to prevent
injury to third persons or property of third persons. The Lessee shall cooperate
fully with the Lessor and any additional insured or loss payee and all insurance
companies providing insurance pursuant to Section 10 hereof in the investigation
and defense of any claims or suits arising from the ownership, operation or use
of any Equipment or ownership, use, or occupancy of the Property and the Lessor
and any Indemnified Person shall comply, at the expense of the Lessee, with all
reasonable requests for assistance of the Lessee and any insurance companies in
connection therewith; provided, that nothing contained in this paragraph (c)
shall be construed as imposing on the Lessor any duty to investigate or defend
any such claims or suits. The Lessee shall comply and shall use reasonable
efforts to cause all Persons using or operating Equipment or using or occupying
Property to comply with all Insurance Requirements and Legal Requirements
applicable to such Property or Equipment and to the acquiring, titling,
registering, leasing, insuring, using, occupying, operating and disposing of
Property

or Equipment, and the licensing of operators thereof; except any Legal
Requirements, the non-compliance with which, individually or in the aggregate,
(i) will not place either the Lessor or any Assignee in any danger of monetary
civil liability for which the Lessor or any Assignee is not adequately
indemnified (the Lessee's obligations under Section 11 of this Lease shall be
deemed to be adequate indemnification if no Event of Default exists) or any
other material civil liability or penalty or subject the Lessor or any Assignee
to any criminal liability as a result of a failure to comply therewith and (ii)
will not result in a material diminution in the value of any Property or
Equipment or in any material risk of the loss, sale or forfeiture or loss of use
of any thereof.

                  (d) Upon at least five (5) Business Days written notice (or
upon two (2) Business Days written notice if an Event of Default shall have
occurred and be continuing), the Lessor or any Assignee or any authorized
representative of either may during reasonable business hours from time to time
inspect Property or Equipment and deeds, registration certificates, certificates
of title and related documents covering Property or Equipment wherever the same
may be located, but neither the Lessor nor any Assignee shall have any duty to
make any such inspection; provided that the Lessee shall be permitted to
withhold from the Lessor or any Assignee any information with respect to its
business or work products not related to any Property or Equipment. The Lessor
may recover from Lessee as Additional Rent (i) the reasonable costs and expenses
associated with any inspection of the Ammonia Project, in an amount not to
exceed, when aggregated with (A) the expenses referred to in clause (i) of
subsection 9.4 of the Agreement for Lease, and (B) the fees and expenses of the
Lessor and any Assignee for engineering and legal services, $650,000 in the
aggregate, (ii) the reasonable costs and expenses associated with any such
inspection, and the fees and expenses of the Lessor and any Assignee for legal
and engineering services which are incurred following the occurrence and during
the continuation of any Event of Default throughout the Lease Term of the
Ammonia Project and (iii) all of the Lessor's and any Assignee's mortgage
recordation, liens and filing fees, and all out-of-pocket expenses of the
Lessor's legal counsel and any Assignee's legal counsel, and all out-of-pocket
expenses of any Assignee.

                  (e) The Lessee shall not, without the prior written consent of
the Lessor, permit, or suffer to exist, any Lien on, other than Permitted Liens
or those Liens placed thereon by, or arising from, the Lessor's own actions or
which are subject to a Permitted Contest, nor may it assign any right or
interest herein or in, any Property or Equipment. The Lessee shall not, without
the prior written consent of the Lessor, sublease or otherwise relinquish
possession of any Property or Equipment, except that (i) the Lessee may
relinquish possession of Property or Equipment to any contractor for use in
performing work for the Lessee on such Property or Equipment; provided, that
such relinquishment of possession shall in no way affect the obligations of the
Lessee or the rights of the Lessor hereunder and with respect to the Property or
Equipment and (ii) the Lessee may sublease any Parcel of Property or Unit of
Equipment to a Person within the Arcadian Lease Group; provided that (A) the
terms of the instrument of sublease shall be subject to the prior written
approval of the Lessor which approval shall not be unreasonably withheld or
delayed, (B) each such sublease shall expressly be made subject and subordinate
to the provisions hereof, shall not permit any act or omission not permitted
hereby and shall, at the sole option of the Lessor, by its terms be subject to
termination upon the termination for any reason of this Lease, (C) no such
sublease shall modify or limit any right or power of the Lessor hereunder or
affect or reduce any obligation of the Lessee hereunder, and all such
obligations shall continue in full force and effect as obligations of a
principal and not of a guarantor or surety, as though no such subletting had
been made, and (D) any such sublease made otherwise than as expressly permitted
by this paragraph (e) shall be void ab initio and of no force and effect. As
additional security to

the Lessor for the performance of the Lessee's obligations under this Lease, the
Lessee hereby assigns to the Lessor all of its right, title and interest in and
to all subleases permitted hereby and agrees to cause any sublessee to enter
into attornment agreements with the Lessor as the Lessor shall request. The
Lessor shall have the present and continuing right to collect and enjoy all
rents and other sums of money payable under any such sublease, and the Lessee
hereby irrevocably assigns such rents and other sums to the Lessor for the
benefit and protection of the Lessor; provided, that unless an Event of Default
shall have occurred and be continuing hereunder, the Lessee shall be entitled to
collect and enjoy such rents and other sums. The Lessee shall, within thirty
(30) days after the execution of any such sublease, deliver a conformed copy
thereof to the Lessor. Nothing contained in this Lease shall be construed as
constituting the consent or request of the Lessor, express or implied, to or for
the performance by any contractor, laborer, materialman or vendor of any labor
or services or for the furnishing of any materials for any construction,
alteration, addition, repair or demolition of or to any Property or Equipment or
any part thereof. Notice is hereby given that the Lessor will not be liable for
any labor, services or materials furnished or to be furnished to the Lessee, or
to anyone holding any Property or Equipment or any part thereof through or under
the Lessee, and that no mechanics' or other liens for any such labor, services
or materials shall attach to or affect the interest of the Lessor in and to the
Property or Equipment.

                  (f) The Lessee shall register and title all automotive
Equipment in the name of the Lessor except that, where required or permitted by
law or regulation, Equipment may, with the written approval of the Lessor be
registered (but not titled) in the name of the Lessee. If requested by the
Lessor, the Lessee shall cause one of its officers to hold in his custody and
control all registration certificates and certificates of title covering
automotive Equipment, as custodian for the Lessor. The Lessee agrees to cause
such officer to furnish to the Lessor, upon reasonable request, a certificate to
the effect that all registration certificates and certificates of title pursuant
to any Legal Requirement have been obtained and are being held on behalf of the
Lessor.

                  (g) The Lessee shall comply with all Legal Requirements
pursuant to which it is necessary that a Unit of Equipment or any component
thereof be labeled to provide notice of the Lessor's or any Assignee's interest
in such Unit of Equipment.

                  (h) If any Lien or charge of any kind or any judgment, decree
or order of any court or other governmental authority (including, without
limitation, any state or local tax lien affecting the Property or Equipment),
whether or not valid, shall be asserted or entered which might interfere with
the due and timely payment of any sum payable or the exercise of any of the
rights or the performance of any of the duties or responsibilities under this
Lease, the Lessee shall (and without limiting any other obligation of the Lessee
hereunder), upon a Responsible Officer's obtaining knowledge thereof or upon
receipt of notice to that effect from the Lessor, promptly take such action as
may be necessary to prevent or terminate such interference.

                  SECTION 9. MAINTENANCE, IMPROVEMENT AND REPAIR OF PROPERTY
                             OR EQUIPMENT.

                  (a) The Lessor, so long as no Event of Default shall have
occurred and be continuing, hereby assigns and agrees to make available to the
Lessee any and all rights the Lessor may have under any vendor's or
manufacturer's warranties or undertakings with respect to any Property or
Equipment. If any Event of Default shall have occurred and be continuing, the
assignment of such rights from the Lessor to the Lessee shall be deemed to be
suspended.

                                                    CONFIDENTIAL AND PROPRIETARY



                  (b) The Lessee shall pay all costs, expenses, fees and charges
incurred in connection with the Lessor's ownership, and the Lessee's use or
occupancy of any Parcel of Property or the Lessor's ownership, and the Lessee's
use and operation of any Unit of Equipment. Except as otherwise provided in
Section 15 hereof, the Lessee shall at all times, at its own expense, and
subject to reasonable wear and tear, keep Property or Equipment in good
operating order, repair, condition and appearance. The foregoing undertaking to
maintain Property or Equipment in good repair shall apply regardless of the
cause necessitating repair and regardless of whether the Lessee has possession
of the Property or Equipment, and as between the Lessor and the Lessee all risks
of damage to Property or Equipment are assumed by the Lessee.

                  (c) With respect to any Parcel of Property, the Lessee shall
pay: (i) all taxes, assessments, levies, fees, water and sewer rents and
charges, and all other governmental charges, general and special, ordinary and
extraordinary, foreseen and unforeseen, which are, at any time, imposed or
levied upon or assessed against (A) the Parcel, (B) any Basic Rent, any
Additional Rent or other sum payable hereunder or (C) this Lease, the leasehold
estate hereby created, or which arises in respect of the ownership, operation,
occupancy, possession or use of the Parcel; (ii) all gross receipts or similar
taxes (i.e., taxes based upon gross income which fail to take into account all
customary deductions (e.g., ordinary operating expenses, depreciation and
interest) relating to the Parcel) imposed or levied upon, assessed against or
measured by any Basic Rent, or any Additional Rent or other sum payable
hereunder; (iii) all sales, value added, use and similar taxes at any time
levied, assessed or payable on account of the acquisition, leasing or use of the
Parcel; and (iv) all charges of utilities and communications services serving
the Parcel. The Lessee shall not be required to pay any franchise, estate,
inheritance, transfer, income or similar tax of the Lessor (other than any tax
referred to in clause (ii) above) unless such tax is imposed, levied or assessed
in substitution for any other tax, assessment, charge or levy which the Lessee
is required to pay pursuant to this paragraph (c); provided, however, that if at
any time during the term of this Lease, the method of taxation shall be such
that there shall be levied, assessed or imposed on the Lessor a capital levy or
other tax directly on the rents received therefrom, or upon the value of any
Parcel or any present or any future improvement or improvements on any Parcel,
then all such taxes, assessments, levies or charges or the part thereof so
measured or based, shall be payable by the Lessee, but only to the extent that
such taxes would be payable if the Property affected were the only property of
the Lessor, and the Lessee shall pay and discharge the same as herein provided.
The Lessee will furnish to the Lessor, promptly after demand therefor, proof of
payment of all items referred to above which are payable by the Lessee. If any
such assessments may legally be paid in installments, the Lessee may pay such
assessment in installments; in such event, the Lessee shall be liable only for
installments which become due and payable during the Lease Term and any Renewal
Term.

                  (d) The Lessee may make alterations to any Equipment, provided
such alterations do not materially impair the value or utility of such Equipment
and shall make, at its expense, all modifications and improvements which are
necessary pursuant to any Legal Requirement or Insurance Requirement. Any
improvements or additions to any Equipment shall become and remain the property
of the Lessor, except that any addition to Equipment made by the Lessee, if it
can be removed from such Equipment without impairing the value or utility
thereof or without violating Legal Requirements or Insurance Requirements, may
be removed by the Lessee, and if removed title thereto shall pass to the Lessee.
Any improvements or additions shall be covered by a revised Unit Leasing Record
or AFL Unit Leasing Record which the Lessee agrees to furnish promptly.

                  (e) So long as no Event of Default shall have occurred and be
continuing, the Lessee may, at its expense, make additions to and alterations to
any Parcel of Property; provided, that upon completion of such additions or
alterations (i) neither the fair market value or utility of the Parcel of
Property shall be materially impaired, (ii) such additions or alterations shall
not result in a change of use of such Parcel of Property and (iii) no exterior
walls of any building or other improvement constituting a part of a Parcel of
Property shall be demolished unless the Lessee has made adequate provision
according to sound and prudent engineering and architectural standards to
preserve and maintain the structural integrity of the Parcel of Property and for
the restoration of such Parcel of Property to a structurally sound architectural
whole. Any and all such additions and alterations shall be and remain part of
the Parcel of Property and shall be subject to this Lease. Notwithstanding
anything contained herein, the Lessee shall not perform any addition or
alteration to any Parcel of Property which would have an estimated cost in
excess of $5,000,000, without the Lessor's prior written consent, which consent
shall not be unreasonably withheld.

                  (f) The Equipment constituting or included in the Ammonia
Project and leased by the Lessee shall be maintained, repaired, refurbished or
replaced by the Lessee when necessary in order to ensure that all Equipment
located at the Ammonia Project will include the Equipment listed on the AFL Unit
Leasing Record with respect to the Ammonia Project or replacements for such
Equipment of the kind, quality and in the quantities included in the AFL Unit
Leasing Record with respect to the Ammonia Project (provided that the Lessee
may, subject to compliance with other requirements of this Section 9, replace
Equipment at the Ammonia Project with equipment of different kind, quality and
in different quantities if such replacement equipment is of equal or greater
value and serviceability) and will be in such condition and sufficient to allow
the Ammonia Project to be operated in accordance with industry standards as an
ammonia production plant. As equipment is substituted at the Ammonia Project for
Equipment at the Ammonia Project and subject to this Lease, title to such
substitute equipment shall automatically vest in the Lessor and such equipment
shall be subject to this Lease and title to the existing Equipment at the
Ammonia Project for which such equipment is being substituted shall be
transferred by the Lessor at the direction of the Lessee.

                  (g) The Lessee shall (i) maintain the Ammonia Project in a
condition (ordinary wear and tear excepted) such that Ammonia Project will have
the capacity and functional ability to perform, in normal commercial operation,
the functions for which it was designed at the operational levels contemplated
therefor and (ii) operate, service, maintain and repair the Ammonia Project and
replace all necessary components thereof (A) so that the condition and operating
efficiency will be maintained and preserved (ordinary wear and tear excepted) in
accordance with industry standards for an ammonia production plant, (B) in
accordance with such operating standards as shall be required to take economic
advantage of and enforce all available warranties to the extent such warranties
are material to the value or operation of the Ammonia Project, (C) in accordance
with all Insurance Requirements applicable to the Ammonia Project and (D) in
accordance with all Governmental Actions relating thereto.

                  (h) The Lessee has obtained or will obtain prior to the time
required and shall maintain in full force and effect all operating licenses, if
any, relating to the Ammonia Project which are required for the operation of the
Ammonia Project.

                  SECTION 10. INSURANCE.

                  (a) General Liability Insurance with Respect to Equipment. The
Lessee will carry at its own expense general liability insurance and property
damage insurance with respect to all Equipment (i) in amounts which are not less
than the general liability and property damage insurance applicable to similar
equipment owned, leased or held by the Lessee; provided, that in no event shall
such amounts in respect of the Ammonia Project be less than $5,000,000 per
occurrence, (ii) of the types usually carried by Persons engaged in the same or
a similar business, similarly situated with the Lessee, and owning or operating
similar equipment and which cover risk of the kind customarily insured against
by such Persons, and (iii) which are maintained in effect with insurers of
recognized responsibility and reputation satisfactory to the Lessor and any
Assignee. The insurance required by this paragraph (a) may be subject to such
deductibles and the Lessee may self-insure with respect to the required coverage
to the extent consistent with the Lessee's customary practice with respect to
similar property owned by the Lessee.

                  (b) Insurance Against Loss or Damage to Equipment. The Lessee
will maintain in effect with insurers of recognized responsibility and
reputation satisfactory to the Lessor and any Assignee , at its own expense,
all-risk physical damage insurance with respect to all Equipment, which is of
the type usually carried by Persons engaged in the same or similar business,
similarly situated with the Lessee, and owning or operating similar equipment
and which cover risk of the kind customarily insured against by such Persons,
and in substantially the amount applicable to similar equipment owned, leased or
held by the Lessee; provided, that such insurance shall at all times be in an
amount not less than the aggregate Acquisition Cost of such Unit of Equipment.
The insurance required by this paragraph (b) may be subject to reasonable
deductibles and the Lessee may self-insure with respect to the required coverage
to the extent consistent with the Lessee's customary practice with respect to
similar property owned by the Lessee.

                  (c) Insurance with respect to Property. The Lessee will
maintain or cause to be maintained insurance of the following character, on each
Parcel of Property:

                  (i)      All risk insurance coverage against losses by fire
                           and lightning and other risks for the full insurable
                           replacement value of each Parcel of Property or
                           portion or component thereof, with agreed amount
                           endorsement or endorsements providing equivalent
                           protection, including loss by windstorm, flood, hail,
                           explosion, riot (including riot attending a strike),
                           civil commotion, aircraft, vehicles, smoke damage,
                           and vandalism and malicious mischief, in amounts not
                           less than the full insurable replacement value of all
                           buildings and other improvements on each Parcel of
                           Property, but in no event less than the Acquisition
                           Cost of each Parcel of Property. The term "full
                           insurable replacement value" as used herein means the
                           actual replacement cost, including the costs of
                           debris removal, but excluding the cost of
                           constructing foundation and footings.

                  (ii)     Comprehensive general public liability insurance
                           covering the legal liability of the Lessor and the
                           Lessee against claims for bodily injury, death or
                           property damage, occurring on, in or about each
                           Parcel of Property or occurring as a result of
                           ownership of facilities located on each Parcel of
                           Property or as a result of the use of products or
                           materials manufactured, stored, processed,
                           constructed or sold, or services rendered, on each
                           Parcel

                           of Property, in the minimum amount of $5,000,000 with
                           respect to any one occurrence, accident or disaster
                           or incidence of negligence.

                  (iii)    The Lessee shall comply with applicable workers'
                           compensation laws of the jurisdiction where each
                           Parcel of Property is located, and shall maintain
                           such insurance if and to the extent necessary for
                           such compliance.

                  (iv)     Such other insurance, in such amounts and against
                           such risks, as is customarily maintained by operators
                           of similar properties.

The insurance required under this paragraph (c) shall be maintained in effect
with insurers of recognized responsibility and reputation satisfactory to the
Lessor and any Assignee. Such insurance may provide for such deductibles and the
Lessee may self-insure with respect to the required coverage to the extent
consistent with the Lessee's customary practice with respect to similar property
owned by the Lessee.

                  Insurance claims by reason of damage or destruction to any
Parcel of Property shall be adjusted by the Lessee, subject to the approval of
the Lessor, which approval the Lessor agrees not to unreasonably withhold or
delay; provided, that if the amount claimed exceeds $5,000,000, the Lessor may
participate in such adjustment, at the Lessee's expense.

                  (d) Political Risk Insurance. Commencing on or before the date
which is one hundred twenty (120) days from the date hereof, the Lessee shall,
as agent for the Lessor, procure or cause to be procured and maintain or cause
to be maintained in respect of Property or Equipment not located in the United
States, for the Lessor, with the Multilateral Investment Guaranty Agency or such
other insurance company as shall be reasonably acceptable to the Lessor, a
policy of political risk insurance covering (i) transfer restrictions, (ii)
expropriation and (iii) to the extent reasonably available from public or
private market insurers or any combination thereof, war and civil disturbance;
provided, that the amount of such political risk insurance in respect of the
Ammonia Project shall equal or exceed the Acquisition Cost of the Ammonia
Project less the sum of (A) the cash on deposit in the Cash Reserve Account and
(B) the value of all investments of such cash and investments of earnings on
investments of such cash (as determined pursuant to the CRA Agreement). Upon
obtaining such policy of political risk insurance, the Lessee will furnish to
the Lessor evidence reasonably satisfactory to the Lessor that such insurance
complies with the terms of this paragraph (d).

                  (e) Additional Insureds; Notice. Any policies of insurance
carried in accordance with this Section 10 and any policies taken out in
substitution or replacement for any such policies (i) shall name the Lessor, the
general partner of the Lessor and its shareholders, officers and directors, the
limited partners of the Lessor, and each Assignee as additional insureds (the
"Additional Insureds"), as their respective interests may appear in relation to
the Property and Equipment (but without imposing upon any such Person any
obligation imposed on the insured, including, without limitation, the liability
to pay the premium for any such policy), (ii) with respect to insurance carried
in accordance with the preceding paragraphs (b), (c)(i) and (c)(iv) shall name
the Assignee, if any, or the Lessor, if no Assignment has been made, as loss
payee, (iii) with respect to insurance carried in accordance with the preceding
paragraphs (b) and (c), shall provide that as against the Lessor the insurers
shall waive any rights of subrogation; provided, that the exercise by insurers
of rights of subrogation derived from rights retained by the Lessee shall not in
any way delay payment of a claim that would otherwise be paid by such

insurers, (iv) shall provide that if the insurers cancel such insurance for any
reason whatsoever, or any substantial change is made in the coverage or the same
is allowed to lapse for nonpayment of premium or such insurance coverage is
reduced, such cancellation, change, lapse or reduction shall not be effective as
to the Additional Insureds or any loss payee for ten (10) days after receipt by
the Lessor and any Assignee of written notice by such insurers of such
cancellation, change, lapse or reduction, and (v) shall provide that in respect
of the interest of the Additional Insureds or any loss payee in such policies
the insurance shall not be invalidated by any action or inaction of the Lessee
or any other Person (other than an Additional Insured in respect of its own
interest) and shall insure the interests of the Additional Insureds or any loss
payee as they appear, regardless of any breach or violation of any warranties,
declarations or conditions contained in such policies by the Lessee or any other
Person; provided that, subject to the specific requirements of this Section 10,
the coverage afforded the Additional Insureds shall not be broader than the
coverage afforded the named insured. Each liability policy (A) shall be primary
without right of contribution from any other insurance which is carried by the
Lessor with respect to its interest as such in the Property or Equipment and (B)
shall expressly provide that all of the provisions thereof, except the limits of
liability, shall operate in the same manner as if there were a separate policy
covering each insured.

                  (f) Application of Insurance Proceeds for Loss or Taking. As
between the Lessor and the Lessee it is agreed that any insurance payments
received as the result of the occurrence of (i) any event of loss described in
paragraph (c) of Section 15 hereof with respect to any Parcel of Property or
Unit of Equipment, or (ii) any event of Taking described in Section 16 hereof
shall be paid to an account of the Lessor and disposed of, as set forth in
paragraph (c) of Section 15 hereof.

                  (g) Application of Insurance Proceeds for Other than Loss or
Taking. As between the Lessor and the Lessee, the insurance proceeds of any
property damage loss to any Property or Equipment will be held in an account of
the Lessor and applied in payment (or to reimburse the Lessee) for repairs or
replacement in accordance with the terms of paragraph (b) of Section 15 hereof;
provided that in the event that any insurance payments received pursuant to this
paragraph (g) are less than $2,000,000, such payments shall be paid to, or
retained by, the Lessee. The Lessee shall be entitled (i) to receive the amounts
so deposited against certificates, invoices or bills satisfactory to the Lessor,
delivered to the Lessor from time to time as such work or repair progresses, and
(ii) to direct the investment of the amounts so deposited as provided in
paragraph (h) of this Section 10. To the extent that the cost of such work or
repair shall exceed the amount of proceeds, the Lessee shall make payment
thereof. Any moneys remaining in the aforesaid account after final payment for
repairs has been made shall be paid to the Lessee.

                  (h) Investment. The Lessor, at the Lessee's instruction and
risk, may invest the amounts deposited with the Lessor pursuant to paragraph (g)
of this Section 10 in any investments permitted under a Credit Agreement. Such
investments shall mature in such amounts and on such dates so as to provide that
amounts shall be available on the draw dates sufficient to pay the amounts
requested by and due to the Lessee. Any interest earned on investments of such
funds shall be paid to the Lessee. The Lessor shall not be liable for any loss
resulting from the liquidation of any such investment and the Lessee shall bear
the risk of such loss, if any.

                  (i) Application in Default. Any amount referred to in
paragraphs (e), (f), (g) or (h) of this Section 10 which is payable to the
Lessee shall not be paid to the Lessee or, if it has been previously paid to the
Lessee, shall not be retained by the Lessee, if at the time of such

payment an Event of Default shall have occurred and be continuing. In such
event, all such amounts shall be paid to and held by the Lessor as security for
the obligations of the Lessee hereunder or, at the Lessor's option, applied by
the Lessor toward payment of any of such obligations of the Lessee at the time
due hereunder as the Lessor may elect. At such time as there shall not be
continuing any Event of Default, all such amounts at the time held by the Lessor
in excess of the amount, if any, which the Lessor shall have elected to apply as
above provided shall be paid to the Lessee.

                  (j) Certificates, etc. On or before the execution of this
Lease, on the Effective Date with respect to any Parcel of Property or Unit of
Equipment, and annually on or before the anniversary of the date of this Lease,
the Lessee will furnish to the Lessor certificates of an independent insurance
broker reasonably satisfactory to the Lessor or other evidence reasonably
acceptable to the Lessor certifying that the insurance then carried and
maintained on each Parcel of Property or Unit of Equipment complies with the
terms hereof. In addition, on or prior to the date that is one year from the
date of this Lease, the Lessee will furnish to the Lessor the insurance policies
with respect to the insurance required by this Section 10.

                  (k) Use or Operation of Property and Equipment. The Lessee
covenants that it will not use or operate any Equipment or use or occupy any
Property or permit the use or occupancy of any Property or the use or operation
of any Equipment at a time when the insurance required by this Section 10 is not
in force with respect to such Property or Equipment.

                  (l) Prosecution of Claims. The Lessee may, so long as no Event
of Default shall have occurred and be continuing, at its cost and expense,
prosecute any claim against any insurer or contest any settlement proposed by
any insurer, and the Lessee may, so long as no Event of Default shall have
occurred and be continuing, bring any such prosecution or contest in the name of
the Lessor, the Lessee, or both, and the Lessor will join therein at the
Lessee's request; provided, that the Lessee shall indemnify the Lessor against
any losses, costs or expenses (including reasonable attorneys' fees) which the
Lessor may incur in connection with such prosecution or contest whether or not
it is at the request of the Lessee.

                  SECTION 11. INDEMNITIES.

                  The Lessee shall, and hereby does, indemnify and hold harmless
the Lessor, Merrill Lynch, Merrill Leasing, any Assignee, any successor or
successors, and any Affiliate of each of them, and their respective officers,
directors, incorporators, shareholders, partners (general and limited,
including, without limitation, the general and limited partners of the Lessor),

prepayment of any borrowing to which such interest rate swap, cap, collar or
other financial hedging arrangement relates), operation, transportation, repair,
return, delivery or control of any Property or Equipment or the past, present or
future presence or the release of hazardous substances on, under, to or from, or
the generation or transportation of hazardous substances to or from, or the
failure to report, disclose or remediate the foregoing with respect to any
Property or Equipment, leased or to be leased hereunder or any Operative
Document or any transaction contemplated by any thereof, including any failure
by the Lessee to comply with any provision of any thereof, (i) except to the
extent that such costs are included in the Acquisition Cost of such Property or
Equipment within the limitations provided in paragraph (a)(v) of Section 3
hereof (or within any change of such limitations agreed to in writing by the
Lessor and the Lessee), (ii) except for any general administrative expenses of
the Lessor, (iii) except the income taxes with respect to which indemnification
is excluded under paragraph (c) of this Section 11 and (iv) except that this
indemnity shall not increase any payment required to be made by the Lessee
pursuant to Section 13 of this Lease;

                  (b) The assertion of any claim or demand based upon any
infringement or alleged infringement of any patent or other right, by or in
respect of any Property or Equipment; provided, however, the Lessor will make
available to the Lessee the Lessor's rights under any similar indemnification
arising from any manufacturer's or vendor's warranties or undertakings with
respect to any Property or Equipment;

                  (c) All U.S. Federal, state, county, municipal, foreign
(including, without limitation, the Republic of Trinidad and Tobago) or other
fees and taxes of whatsoever nature, including but not limited to license,
qualification, franchise, sales, use, withholding, gross income, gross receipts,
ad valorem, business, personal property, real estate, value added, excise, motor
vehicle, occupation fees and stamp or other taxes or tolls of any nature
whatsoever, and penalties and interest thereon, whether assessed, levied against
or payable by the Lessor or otherwise, with respect to any Property or Equipment
or the acquisition, purchase, sale, rental, use, operation, control, ownership
or disposition of any Property or Equipment (including, without limitation, any
claim by any Governmental Authority for transfer tax, transfer gains tax,
mortgage recording tax, filing or other similar taxes or fees in connection with
the acquisition of any Property by the Lessor or otherwise in connection with
this Lease) or measured in any way by the value thereof or by the business of,
investment in, or ownership by the Lessor with respect thereto; provided, that
this indemnity shall not apply to Federal net income taxes, or to state and
local net income taxes, except that such indemnity shall apply to state and
local net income taxes (A) to the extent imposed by reason in whole or in part
of (1) a relation or asserted relation of any such taxing jurisdiction to the
Property or Equipment or to the transactions contemplated herein or (2) the
actual or deemed use by any Person of the Property or Equipment in such taxing
jurisdiction, other than in the case of both clauses (1) and (2), taxes to the
extent such taxes would have been imposed by a taxing jurisdiction because of a
relationship between the Lessor and such taxing jurisdiction without regard to
the circumstances described in clauses (1) and (2), and (B) to the extent
imposed as a result of the inability to claim, disallowance or other loss by
Nitrogen Leasing Company, Limited Partnership of deductions customarily allowed
in computing net income (e.g., interest expense, financing, administrative,
ordinary operating expenses and other fees and expenses, but not including
depreciation in respect of Property or Equipment); or

Lease or any other Operative Document or of any contracts or agreements to which
the Lessee is a party or by which

it is bound or of any laws, rules, regulations, orders, writs, injunctions,
decrees, consents, approvals, exemptions, authorizations, licenses and
withholdings of objection, of any governmental or public body or authority and
all other Legal Requirements.

                  The Lessee shall forthwith upon demand reimburse any
Indemnified Person for any sum or sums expended with respect to any of the
foregoing or, upon request from any Indemnified Person, shall pay such amounts
directly. Any amount payable to any Indemnified Person pursuant to this Section
11 shall be paid promptly upon receipt of a written demand therefor from such
Indemnified Person accompanied by a written statement describing in reasonable
detail the claims which are the subject of and basis for such indemnity and the
computation of the amount so payable. Any payment made to or on behalf of any
Indemnified Person pursuant to this Section 11 shall be increased to such amount
as will, after taking into account all taxes imposed with respect to the accrual
or receipt of such payment (as the same may be increased pursuant to this
sentence), equal the amount of the payment, reduced by the amount of any savings
in such taxes actually realized by the Indemnified Person as a result of the
payment or accrual of the amounts in respect of which the payment to or on
behalf of the Indemnified Person hereunder is made. To the extent that the
Lessee in fact indemnifies any Indemnified Person under the indemnity provisions
of this Lease, the Lessee shall be subrogated to such Indemnified Person's
rights in the affected transaction and shall have a right to determine the
settlement of claims therein.

                  The indemnities contained in this Section 11 shall survive and
shall not be affected by any termination of this Lease as a whole or in respect
of any Parcel of Property or Unit of Equipment leased hereunder or any failure
or refusal of the Lessee to accept any Property or Equipment acquired or ordered
pursuant to the terms hereof.

                  Notwithstanding any provisions of this Section 11 to the
contrary, the Lessee shall not indemnify and hold harmless any Indemnified
Person against any claims and liabilities arising solely from the gross
negligence or willful misconduct of such Indemnified Person. Each Indemnified
Person shall give prompt notice to the Lessee by telephone confirmed in writing
of any event or circumstance which will give rise to a claim for indemnification
but delay or failure in giving such notice shall not affect the Lessee's
obligations hereunder except to the extent that any increase in liability is a
direct result of such failure or delay.

                  In the event any Indemnified Person shall be a party defendant
to any litigation in respect of which indemnification is applicable under this
Section 11, such Indemnified Party shall give prompt notice thereof to the
Lessee by telephone and in writing. No failure or delay of such Indemnified
Person to give the notice required by this Section 11 shall excuse the
obligation of the Lessee to indemnify each Person with respect to such
litigation except to the extent that any increase in liability is a direct
result of such failure or delay. In the event any claim, action, proceeding or
suit is brought against an Indemnified Person with respect to which the Lessee
has acknowledged its obligation to indemnify such Indemnified Person (provided
that such acknowledgement shall not be binding upon the Lessee in the event of a
final determination in a judicial proceeding that the Lessee was not liable in
such claim, action, proceeding or suit), the Lessee shall have the right to
assume the defense thereof, including the employment at its expense of counsel;
provided that the Lessee shall not have such right, to the extent that such
Indemnified Person shall deliver to the Lessee a written notice waiving the
benefits of the indemnification of such Indemnified Person provided by this
Section 11 in connection with such claim, action, proceeding or suit.
Notwithstanding the foregoing, if (i) any criminal proceeding is brought

against an Indemnified Person, (ii) the claim, action, proceeding or suit seeks
damages of more than $10,000,000 or material non-monetary civil liability or
penalty, or (iii) independent counsel to an Indemnified Person shall advise such
Indemnified Person in writing that there may be a conflict of interest or
defenses available to the Indemnified Person which are different from, or
additional to, and may conflict with those available to the Lessee, the Lessee
shall not have the right to assume the defense of any such action on behalf of
the Indemnified Person if such Indemnified Person chooses to defend such action,
and all reasonable costs, expenses and attorneys' fees incurred by the
Indemnified Person in defending such action, including any damages or any
settlement amount, shall be borne by the Lessee. Notwithstanding the assumption
of its defense by the Lessee pursuant to this paragraph, any Indemnified Person
shall have the right to employ separate counsel and to participate in its
defense, but the fees and expenses of such counsel shall be borne by the
Indemnified Person. In addition, the Lessee will not be liable for any
settlement of any claim, action, proceeding or suit unless the Lessee has
consented thereto in writing (which consent shall not be unreasonably withheld
or delayed). Any decision by an Indemnified Person to employ its own counsel
rather than counsel selected by the Lessee (whether or not at the Lessee's
expense) shall in no way affect any rights of such Indemnified Person otherwise
arising under this Section 11.

                  SECTION 12. LEASE RENEWAL.

                  (a) Provided that no Event of Default has occurred and is
continuing as at the date of such request, if the Lessee shall, not earlier than
450 days and not later than one year prior to the last day of the Initial Term,
request in writing that the Lessor obtain bank borrowings on terms acceptable to
it and the Lessee in order to finance the Lessor's ownership of the Property and
Equipment during the Renewal Term, the Lessor shall make reasonable efforts to
arrange for bank commitments to provide such financing.

                  (b) The Lessor will advise the Lessee and Arcadian Corporation
in writing not later than 300 days prior to the last day of the Initial Term as
to whether it has been able to obtain bank commitments on terms and conditions
acceptable to it to finance the Property and Equipment for the period of Renewal
Term. In such notice, the Lessor shall identify such terms and conditions. In
order to renew the lease of the Property and Equipment for the Renewal Term, the
Lessee must notify the Lessor in writing within thirty (30) days of its receipt
of the foregoing notice of the Lessor, indicating (i) whether the terms and
conditions of such financing are acceptable to it and (ii) whether, if Arcadian
Corporation does not exercise its Purchase Option or, having exercised such
option, Arcadian Corporation fails to effect the purchase contemplated thereby,
the Lessee agrees to lease the Property and Equipment for the Renewal Term. The
notice of the Lessee contemplated by the preceding sentence shall be
irrevocable.

                  (c) The lease of the Property and Equipment shall not be
renewed for the Renewal Term if (i) the Lessor shall not obtain bank commitments
to finance the Property and Equipment on terms and conditions acceptable to it
and the Lessee, (ii) the Lessee shall not give the notice of renewal set forth
in paragraph (b) above, (iii) Arcadian Corporation shall purchase the Property
and Equipment pursuant to the exercise of the Purchase Option or (iv) the Lessor
and the Lessee shall not have agreed on the Lease Termination Amount for the
Renewal Term.

                  (d) The Lessor shall schedule the closing of the financing
contemplated by the bank commitments on or before the date which is six (6)
months prior to the end of the Initial Term. The Lessor shall notify the Lessee
in writing promptly of the closing of such financing or


                                       37
<PAGE>   41

that such financing shall have failed to close on such scheduled date. Upon the
date of such closing the Property and Equipment shall, subject to the terms and
conditions of this Lease, be leased hereunder for the Renewal Term. If the
closing shall not occur on or before the date which is six (6) months prior to
the last day of the Initial Term, then the lease of the Property and Equipment
shall terminate on the last day of the Initial Term and the Lessee shall comply
with its obligations with respect to such termination as set forth in paragraph
(b) of Section 13 hereof.

                  SECTION 13. LEASE EXPIRATION.

                  (a) In the event Arcadian Corporation has not purchased all
Property and Equipment under this Lease pursuant to the Purchase Option and the
Lessee desires to terminate this Lease with respect to such Property and
Equipment, the Lessee shall provide notice to Lessor of such intention at least
five (5) months prior to the expiration of the Lease Term.

                  (b) In the event (x) the Lessee provides the termination
notice contemplated in paragraph (a) above or (y) the circumstances referred to
in the last sentence of paragraph (d) of Section 12 shall be applicable, the
Lessee hereby covenants to the Lessor (the "Expiration Covenants") as follows:
(A) on the Lease Termination Date, (i) no Event of Default or Potential Default
shall have occurred and be continuing, (ii) no Parcel of Property shall be
undergoing any repairs, additions or alterations that would have a material
adverse effect on the fair market value of such Parcel of Property, (iii) each
Parcel of Property and Unit of Equipment shall be in compliance with all Legal
Requirements, except any Legal Requirements, the non-compliance with which,
individually or in the aggregate, (1) will not place either the Lessor or any
Assignee in any danger of any monetary civil liability for which the Lessor or
any Assignee is not adequately indemnified (the Lessee's obligations under
Section 11 of this Lease shall be deemed to be adequate indemnification if no
Event of Default exists) or any other material civil liability or penalty or
subject the Lessor or any Assignee to any criminal liability as a result of a
failure to comply therewith and (2) will not result in a material diminution in
the value of any Property or Equipment or in any material risk of the loss, sale
or forfeiture or loss of use of any thereof, (B) five (5) months prior to the
Lease Termination Date, the Lessee shall at its expense deliver to the Lessor an
environmental audit satisfactory in form and substance to the Lessor in its
reasonable discretion, the conclusion of which shall be satisfactory to the
Lessor in its reasonable discretion, and prepared by an independent
environmental consultant or engineer satisfactory to the Lessor in its sole
discretion, addressing the environmental hazards or liabilities associated with
any Parcel of Property or Unit of Equipment under this Lease and (C) on or prior
to the Lease Termination Date, the Lessee shall deliver to the Lessor a report
of an independent engineer (selected by the Lessor and at the expense of the
Lessee), to the effect that the Property and Equipment under this Lease (i) have
been maintained in accordance with the terms and conditions of Section 9 of this
Lease and (ii) are currently operating in accordance with the design
specifications listed in the appraisal provided to the Lessor pursuant to
Section 4 of the Agreement for Lease.

                  (c) In the event the Lessee has complied with each of the
Expiration Covenants, the Lessee shall on the Lease Termination Date applicable
to a Parcel of Property or Unit of Equipment, terminate this Lease with respect
to such Property and Equipment, surrender such Property and Equipment to the
Lessor and pay to the Lessor the Lease Termination Amount with respect to such
Property and Equipment and all other amounts owing by the Lessee hereunder and
under the other Operative Documents. Upon such surrender, the Lessor shall have
the right to sell such Property and Equipment to a third party and the Lessee
shall have no further right, claim or interest in such Property and Equipment
(it being understood that the Lessor shall


                                       38

be entitled to commence the marketing of such Property and Equipment at any time
subsequent to the first day of the fifth month prior to the Lease Termination
Date, and the Lessee agrees that it shall cooperate in connection therewith). If
the Lessor shall fail to sell the Ammonia Project within seven (7) days of the
surrender thereof by the Lessee, the Assignee shall have the right, but not the
obligation, acting on behalf of the Lessor to sell the Ammonia Project to a
third party. The proceeds of sale received by the Lessor or such Assignee, as
the case may be, from any sale of such Property and Equipment shall be retained
by the Lessor or any Assignee, as the case may be, provided that if the proceeds
of sale, together with the Lease Termination Amount paid by the Lessee, exceed
the Acquisition Cost of such Property and Equipment and all other amounts
payable by the Lessee hereunder and under the other Operative Documents, such
excess shall be paid by the Lessor or such Assignee, as the case may be, to the
Lessee. The Lessee shall use reasonable efforts during the last five (5) months
of the Initial Term with respect to such Property and Equipment (unless this
Lease has been renewed pursuant to Section 12 hereof), and during the last five
(5) months of the Renewal Term, if any, to seek on behalf of the Lessor bona
fide arms-length bids for not less than all such Property and Equipment from
prospective purchasers who are financially capable of purchasing such Property
and Equipment for cash, on an as-is, non-installment sale basis, without
warranty by, or recourse to, the Lessor. The Lessee shall assign to any
purchaser, at such purchaser's request and for no additional consideration, any
and all assignable agreements in the Lessee's name for the acquisition,
construction, storage or transportation of the Property and the Equipment. The
Lessee shall notify the Lessor of the amount of each such bid, and the name and
address of the Person submitting such bid.

                  (d) In the event the Lessee shall surrender such Property and
Equipment to the Lessor or to a purchaser of such Property and Equipment from
the Lessor pursuant to the provisions of this Section 13, on the Lease
Termination Date applicable to such Property and Equipment, the Lessee shall pay
to the Lessor all Basic Rent payable with respect to such Property and Equipment
and any Additional Rent and other amounts owing hereunder and under the other
Operative Documents. Upon payment by the Lessee to the Lessor of all amounts
owing under this Section 13 and delivery of all Property and Equipment under
this Lease to the Lessor or such purchaser, this Lease shall terminate with
respect to such Property and Equipment, except to the extent provided in Section
11 hereof.

                  SECTION 14. CHARACTER OF AMMONIA PROJECT.

                  It is the intention of the Lessor and the Lessee that the
components of the Ammonia Project identified as personal property components in
Exhibit D hereto maintain their character as personal property for commercial
law purposes. The Lessee shall take all such reasonable action to maintain such
character and shall obtain and record such instruments and take such steps as
may be necessary to prevent any Person from acquiring any rights in such
components by reason of such components being deemed to be real property.

                  SECTION 15. LOSS OF OR DAMAGE TO PROPERTY OR EQUIPMENT.

                  (a) The Lessee hereby assumes all risk of loss of or damage to
Property or Equipment, however caused. No loss of or damage to any Property or
Equipment shall impair any obligation of the Lessee under this Lease, which
shall continue in full force and effect with respect to any lost or damaged
Property or Equipment.

                                                    CONFIDENTIAL AND PROPRIETARY


                  (b) In the event of damage of any kind whatsoever to any
Property or Equipment (unless the same is determined by the Lessee in its
reasonable judgment to be damaged beyond repair) the Lessee, at its own cost and
expense, shall place the same in good operating order, repair, condition and
appearance. The Lessee's right to any proceeds paid under any insurance policy
or policies required under Section 10 of this Lease with respect to any such
damage to any Property or Equipment which has been so placed by the Lessee in
good operating order, repair, condition and appearance is governed by paragraph
(f) of Section 10 hereof.

                  (c) If (A) all, or a substantial portion of the Ammonia
Project or any other Property or Equipment is lost, stolen, destroyed, seized,
confiscated, rendered unfit for use or damaged beyond repair (in the reasonable
judgment of the Lessee), (B) the use thereof by the Lessee in the ordinary
course of business is prevented by the act of any third Person or Persons or
governmental instrumentality for a period exceeding one hundred eighty (180)
days or, if shorter, the period ending on the last day of the Initial Term or
the Renewal Term of the Ammonia Project or of such other Property or Equipment,
as applicable, (C) the Ammonia Project or any other Property or Equipment is
attached (other than on a claim against the Lessor as to which the Lessee is not
obligated to indemnify the Lessor) and the attachment is not removed within a
period of one hundred eighty (180) days or, if shorter, the period ending on the
last day of the Initial Term or the Renewal Term of the Ammonia Project or of
such other Property or Equipment, as applicable, (D) a Taking as described in
Section 16 shall occur, or (E) the Ammonia Project or any other Property or
Equipment is damaged and the Lessee elects not to rebuild or repair the Ammonia
Project or such Property or Equipment or such rebuilding or repairs would exceed
twenty-five (25%) of the replacement cost of the Ammonia Project or such
Property or Equipment where such rebuilding or repairs could not, in the
reasonable judgment of the Lessee, restore the Ammonia Project or such Property
or Equipment to its previous working order prior to the expiration of the
Initial Term, or if the Lessee has renewed this Lease pursuant to Section 12
hereof, prior to the expiration of the Renewal Term, then in any such event, (a)
the Lessee shall replace such Property or Equipment with real property or
equipment of a similar like and kind, and of a value not less than the Property
or Equipment being replaced (assuming that the replaced Equipment or Property
was maintained in accordance with the provisions hereof), and the Lessee and the
Lessor shall execute a revised Unit Leasing Record or AFL Unit Leasing Record,
as the case may be, to amend, among other things, the description of such
Property or Equipment, provided that the replacement of any Property with other
real property shall be subject to the prior written consent of the Lessor, which
consent shall not be unreasonably withheld, and to receipt by the Lessor and the
Assignee of all documentation required with respect to the acquisition of
Property and Equipment by the Lessor under the terms of any Credit Agreement or
(b) (i) the Lessee shall promptly notify the Lessor in writing of such event,
(ii) on the Basic Rent Payment Date designated by the Lessee, which shall be a
date within ninety (90) days following such event but not later than the last
day of the Lease Term, the Lessee shall pay to the Lessor an amount equal to
84.5% of the Acquisition Cost of the Ammonia Project or such Property or
Equipment, (iii) the Initial Term or Renewal Term of the Ammonia Project or such
Property or Equipment shall continue until the Basic Rent Payment Date on which
the Lessor receives payment from the Lessee of the amount payable pursuant to
this paragraph (c) and of Basic Rent payable with respect to the Ammonia Project
or such Property or Equipment and any Additional Rent and other amounts owing
hereunder and under the other Operative Documents, and shall thereupon
terminate. Insurance and condemnation proceeds, if any, received by the Lessor
that, together with the amounts paid by the Lessee to the Lessor pursuant to
clause (ii) of the preceding sentence, exceed the aggregate of the Acquisition
Cost of the Ammonia Project or the affected Property or Equipment and all other
amounts payable hereunder and under the other

Operative Documents, shall be paid by the Lessor to the Lessee. For purposes of
this paragraph (c), loss of or damage to a "substantial portion of the Ammonia
Project or any other Property or Equipment" shall be deemed to occur if the
Ammonia Project or such Property or Equipment is unusable for the Lessee's
ordinary business purposes in the reasonable judgment of the Lessee.

                  SECTION 16. CONDEMNATION AND DEDICATION OF PROPERTY;
                              EASEMENTS.

                  (a) If the use, occupancy or title to all or a substantial
portion of the Ammonia Project or any other Parcel of Property is taken,
requisitioned or sold in, by or on account of actual or threatened eminent
domain or confiscation or similar proceedings or other action by any
governmental authority (such events collectively referred to as a "Taking"),
then the Initial Term or Renewal Term shall terminate as provided in paragraph
(c) of Section 15 hereof. Upon receipt of proceeds from any award or sale made
in connection with such Taking, if the Lessee has paid all amounts owing under
paragraph (c) of Section 15 hereof, so long as no Event of Default has occurred
and is continuing, the Lessor shall remit to the Lessee the net amount of such
proceeds remaining after reimbursement for all costs and expenses (including,
without limitation, reasonable attorneys' fees) incurred by the Lessor in
connection with the negotiation and settlement of any proceedings related to
such Taking. A Taking shall be deemed to affect a "substantial portion" of the
Ammonia Project or a Parcel of Property if, after such Taking, the Ammonia
Project or such Parcel of Property is unusable for the Lessee's ordinary
business purposes in the reasonable judgment of the Lessee.

                  (b) If less than a substantial portion of the Ammonia Project
or any other Parcel of Property is subject to a Taking, then this Lease shall
continue in effect as to the portion of the Ammonia Project or such Parcel not
taken and any net proceeds, so long as no Event of Default has occurred and is
continuing, shall be paid to the Lessee; provided that if as a result of a
Taking or Takings of less than substantially all of a Parcel of Property the
aggregate proceeds with respect to any Parcel of Property received is equal to
or greater than $2,000,000, at the Lessee's option, (A) the Lessee shall replace
such Property as provided in clause (a) in the first sentence of paragraph (c)
of Section 15 hereof, or (B) such proceeds shall be paid to the Lessor and the
Acquisition Cost of the affected Parcel shall be reduced by the amount of such
proceeds (such reduction to be evidenced by a revised Unit Leasing Record or AFL
Unit Leasing Record, as the case may be). In the event of a reduction in the
Acquisition Cost of the Ammonia Project, the Lessor shall cause the CRA Bank to
remit to the Lessee an amount equal to 40% of the proceeds paid to the Lessor
pursuant to clause (B) of the immediately preceding sentence.

                  (c) So long as no Event of Default hereunder has occurred and
is continuing, the Lessee shall have the right (i) to grant, obtain or enter
into easements for the benefit of any Parcel of Property, (ii) to voluntarily
dedicate or convey, as required, portions of any Parcel of Property for road,
highway and other public purposes and (iii) to voluntarily execute petitions to
have any Parcel of Property or a portion thereof annexed to any municipality or
included within any utility, highway or other improvement or service district,
provided such annexation has no material adverse effect on the value of such
Parcel of Property. In connection with the Lessee's development of the Property
in accordance with the terms of this Lease, the Lessee shall at all times be
free to enter into and/or execute such agreements, dedications, easements,
conditions, covenants and restrictions in favor of other property owners,
lessees or local agencies as are necessary for the conduct of the Lessee's
operations on the Property. If any monetary

consideration is paid for such easement or dedication, the Lessee shall be
entitled to receive or retain such consideration.

                  Subject to the foregoing provisions of this Section 16(c), the
Lessor will cooperate, without unreasonable delay and at the Lessee's expense,
as necessary and join in the execution of any appropriate instrument or shall
execute any separate instrument as necessary. As a condition precedent to the
Lessee's exercise of any of the Lessee's powers under this Section 16, (i) the
Lessee shall give the Lessor five (5) Business Days' prior written notice of the
proposed action and (ii) the Lessee shall provide to the Lessor a certificate of
the Lessee stating that such action will not in any material respect adversely
affect either the fair market value of such Property or the use of such Property
for its intended purpose, will not affect the Lessor's ability to exercise its
rights and remedies under this Lease and that the Lessee undertakes to remain
obligated under this Lease to the same extent as if the Lessee had not exercised
its powers under this Section 16 and the Lessee will perform all obligations
under such instrument and shall prepare all required documents and provide all
other instruments and certificates as the Lessor may reasonably request. If
requested by the Lessee, the Lessor shall appoint the Lessee as the Lessor's
attorney-in-fact pursuant to a power of attorney for the foregoing purposes.

                  SECTION 17. SURRENDER OF PROPERTY OR EQUIPMENT.

                  (a) Upon termination of the lease of any Property or Equipment
under circumstances in which such Property or Equipment is to be returned to the
Lessor, the Lessee shall surrender and deliver such Property or Equipment to the
Lessor or a designee of the Lessor at the location where such Property or
Equipment is required to be located pursuant to the provisions hereof.

                  (b) Upon the surrender of the Property and Equipment, the
Lessee shall deliver to the Lessor or its designee, all logs, manuals,
inspection data, books and records in the English language, if available, or
with translations in the English language or copies thereof which are applicable
to the Property and Equipment that are in accordance with sound industry
practice customarily retained (or that the Lessee actually did retain) or are
required by law to be retained with respect to similar property and equipment,
including, without limitation, all software and manuals necessary for the
operation of the Ammonia Project in accordance with the design specifications
set forth in the appraisal provided to the Lessor pursuant to Section 4 of the
Agreement for Lease.

                  (c) The Lessee shall be obligated to obtain all Governmental
Actions necessary for the surrender of Property and Equipment hereunder and
permitting the Lessor (without the Lessor being required to change its business
structure or otherwise to suffer any real or potential adverse effect on its
business or that of its Affiliates as a result of such surrender and receipt of
possession) to possess the Ammonia Project with or without the continued
involvement of the Lessee, which Governmental Actions shall be in full force and
effect. In connection with the Lessee's surrender of possession of the Ammonia
Project to the Lessor, the Lessee shall furnish to the Lessor copies certified
by a Responsible Officer of the Lessee of all Governmental Actions necessary to
effect such surrender and receipt of possession.

any Assignee; provided that, if such default is of a nature that it is capable
of being cured but not within such 30 day period and the Lessee shall have
diligently commenced curing such default within such 30 day period and the

curing such default, such 30-day period shall be extended to one hundred eighty

which is outstanding in a principal amount of at least $10,000,000, or under any
evidence of any such Indebtedness or of any mortgage, indenture or other

entitle the landlord under the Site Lease, the Sublease or such Ground Lease to
terminate the Site Lease, the Sublease or such Ground Lease and the term thereof
by the giving of notice to the Lessor without opportunity to cure, as tenant
thereunder, or if any of the terms, covenants or conditions of the Site Lease,

consent of the Lessor and Assignee; or

                  (j) An Event of Default (as defined in the Agreement for

                  SECTION 19. RIGHTS UPON DEFAULT.

                  (a) Upon the occurrence and continuation of any Event of
Default the Lessor may, in addition to exercising any other rights and remedies
available to it under applicable law, do any one or more of the following (if,
within fifteen (15) Business Days of receipt by the Lessee of an Event of
Default Notice (as defined in Section 29(l)), the Lessee has not made a request
to purchase all Parcels of Property and Units of Equipment under Section 29(l)
or, if the Lessee has so made such a request but has not consummated within
thirty (30) Business Days of receipt of the Event of Default Notice such
purchase in full compliance with Section 29(l)):

                  (i)      Terminate the lease of any or all Property or
                           Equipment leased hereunder by written notice to the
                           Lessee, subject to the maximum amount the Lessor
                           shall be entitled to recover from the Lessee, as
                           described in paragraph (f) of this Section 19;

                  (ii)     Whether or not the lease of any Property or Equipment
                           is terminated, take immediate possession of and
                           remove any or all Equipment and other equipment or
                           property of the Lessor in the possession of the
                           Lessee, wherever situated, and for such purpose,
                           enter upon any premises without liability to the
                           Lessee for so doing; provided that the taking of
                           possession of any Property or Equipment shall take
                           place in a commercially reasonable manner;

                  (iii)    Whether or not any action has been taken under
                           paragraph (i) or (ii) above, sell any Property or
                           Equipment (free of or subject to the rights of the
                           Lessee or any other person under this Lease and with
                           or without the concurrence or request of the Lessee);

                  (iv)     Hold, use, occupy, operate, remove, lease or keep
                           idle any or all Property or Equipment as the Lessor
                           in its sole discretion may determine, without any
                           duty to account to the Lessee with respect to any
                           such action or inaction, except that the Lessor
                           agrees that any profit it derives from the occupation
                           or use of any Property or Equipment while exercising
                           its rights under this Section 19 will be applied to
                           reduce the Accrued Default Obligations; and

                  (v)      Exercise any other right or remedy which may be
                           available under applicable law and in general proceed

                           in equity, to enforce the terms hereof or to recover
                           damages for the breach hereof.

                  (b) Suit or suits for the recovery of any default in the
payment of any sum due hereunder or for damages may be brought by the Lessor
from time to time at the Lessor's election, and nothing herein contained shall
be deemed to require the Lessor to await the date whereon this Lease or the term
hereof would have expired by limitation had there been no such default by the
Lessee or no such termination or cancellation.

                  (c) The receipt of any payments under this Lease by the Lessor
with knowledge of any breach of this Lease by the Lessee or of any default by
the Lessee in the performance of

                                                    CONFIDENTIAL AND PROPRIETARY


any of the terms, covenants or conditions of this Lease, shall not be deemed to
be a waiver of any provision of this Lease.

                  (d) No receipt of moneys by the Lessor from the Lessee after
the termination or cancellation hereof in any lawful manner shall reinstate,
continue or extend the Initial Term or the Renewal Term, or affect any notice
theretofore given to the Lessee, or operate as a waiver of the right of the
Lessor to enforce the payment of Basic Rent or Additional Rent or other charges
payable hereunder, or operate as a waiver of the right of the Lessor to recover
possession of any Unit of Equipment or Parcel of Property by proper suit,
action, proceedings or remedy; it being agreed that, after the service of notice
to terminate or cancel this Lease, and the expiration of the time therein
specified, if the default has not been cured in the meantime, or after the
commencement of any suit, action or summary proceedings or of any other remedy,
or after a final order, warrant or judgment for the possession of any Unit of
Equipment or Parcel of Property, the Lessor may demand, receive and collect any
moneys payable hereunder, without in any manner affecting such notice,
proceedings, suit, action, order, warrant or judgment; and any and all such
moneys so collected shall be deemed to be payments on account for the use and
operation of any Unit of Equipment or the use, operation and occupation of any
Parcel of Property, or at the election of the Lessor, on account of the Lessee's
liability hereunder and will be applied to reduce the Accrued Default
Obligations. Acceptance of the keys to any Parcel of Property, or any similar
act, by the Lessor, or any agent or employee of the Lessor, during the term
hereof, shall not be deemed to be an acceptance of a surrender of any Parcel of
Property unless the Lessor shall consent thereto in writing.

                  (e) The Lessee hereby expressly confirms that, in any event,
including after any Event of Default, and notwithstanding any termination of
this Lease or reentry or repossession by the Lessor, the Lessee shall continue
to be liable for, and the Lessor may recover from the Lessee, (i) all Basic Rent
accrued to the date of payment, (ii) any Additional Rent owing with respect to
all Property or Equipment leased by the Lessee, (iii) all amounts payable
hereunder or under any other Operative Document and (iv) all losses, damages,
costs and expenses incurred (including, without limitation, reasonable
attorneys' fees and expenses, commissions, filing fees and sales or transfer
taxes) sustained by the Lessor by reason of such Event of Default and the
exercise of the Lessor's remedies with respect thereto, including, in the event
of a sale by the Lessor of any Property or Equipment pursuant to this Section
19, all costs and expenses associated with such sale. The amounts payable in
clauses (i) through (iv) above are hereinafter sometimes referred to as the
"Accrued Default Obligations". Accrued Default Obligations shall not include any
damages for loss of profits arising from the prospective use, operation and
occupancy by parties other than the Lessee of any Property or Equipment or the
anticipated receipt of income therefrom subsequent to the Lessee's possession of
such Property and Equipment.

                  (f) After an Event of Default, the Lessor may sell its
interest in any Property and Equipment in any commercially reasonable manner
upon any terms that the Lessor deems satisfactory, free of any rights of the
Lessee or any Person claiming through or under the Lessee. In the event of any
such sale or in the event the Lessor elects not to sell any Property or
Equipment, in addition to the Accrued Default Obligations, the Lessor shall be
entitled to recover from the Lessee, as liquidated damages, and not as a
penalty, an amount equal to 84.5% of the Acquisition Cost of any Property or
Equipment under this Lease. Proceeds of any such sale received by the Lessor,
or, in the event the Lessor elects not to sell, proceeds at any time thereafter
received by the Lessor from any sale, occupation, operation, use or lease of any
Property or Equipment (net of all reasonable costs and expenses incurred by the
Lessor in

connection with any sale, occupation, operation, use or lease of any Property or
Equipment) in excess of 15.5% of the Acquisition Cost of such Property or
Equipment, shall be credited against the Accrued Default Obligations the Lessee
is required to pay under this Section 19. If such excess proceeds exceed the
Accrued Default Obligations, or, if the Lessee has paid all amounts required to
be paid under this Section 19, such excess shall be paid by the Lessor to the
Lessee. If the Lessee converts any such Property or Equipment after an Event of
Default, or if such Property or Equipment is lost or destroyed, in addition to
the Accrued Default Obligations, the Lessor may cause the Lessee to pay to the
Lessor, and the Lessee shall pay to the Lessor, as liquidated damages and not as
a penalty, an amount equal to 84.5% of the Acquisition Cost of such Property or
Equipment.

                  (g) In the event of a sale pursuant to this Section 19, upon
receipt by the Lessor of the amounts payable hereunder, the Lessor shall
transfer all of the Lessor's right, title and interest in and to the Property
and Equipment to the purchaser thereof.

                  (h) In addition to its other rights in this Section 19, the
Lessor may exercise its various rights under the Operating Agreement, the
Ancillary Facility Agreements and the Gas Contract or transfer such rights to
the purchaser in a sale.

                  (i) No remedy referred to in this Section 19 is intended to be
exclusive, but each shall be cumulative and in addition to any other remedy
referred to above or otherwise available to the Lessor at law or in equity, and
the exercise in whole or in part by the Lessor of any one or more of such
remedies shall not preclude the simultaneous or later exercise by the Lessor of
any or all such other remedies. No waiver by the Lessor of any Event of Default
hereunder shall in any way be, or be construed to be, a waiver of any future or
subsequent Event of Default.

                  SECTION 20. EQUIPMENT TO BE PERSONAL PROPERTY.

                  It is the intention and understanding of the Lessor and the
Lessee that all Equipment shall be and at all times remain personal property.
The Lessee shall obtain and record such instruments and take such steps as may
be necessary to prevent any Person from acquiring any rights in Equipment
paramount to the rights of the Lessor by reason of such Equipment being deemed
to be real property.

                  SECTION 21. SALE OR ASSIGNMENT BY LESSOR.

                  (a) The Lessor shall have the right to obtain equity and debt
financing for the acquisition and ownership of the Property or Equipment by
selling or assigning its right, title and interest in any or all amounts due
from the Lessee or any third party under this Lease; provided, that any such
sale or assignment shall be subject to the rights and interests of the Lessee
under this Lease.

                  (b) Any Assignee shall, except as otherwise agreed by the
Lessor and such Assignee, have (to the exclusion of the Lessor) all the rights,
powers, privileges and remedies of the Lessor hereunder, and the Lessee's
obligations as between itself and such Assignee hereunder shall not be subject
to any claims or defense that the Lessee may have against the Lessor, other than
the defense of payment or satisfaction of the obligation; provided that the
foregoing shall not be deemed to be a waiver of any claims the Lessee may have
against the Lessor. Upon written

notice to the Lessee of any such assignment, the Lessee shall thereafter make
payments of Basic Rent, Additional Rent and other sums due hereunder to the
Assignee, to the extent specified in such written notice, and only such payments
to the applicable Assignee shall discharge the obligation of the Lessee to the
Lessor hereunder and only to the extent of such payments. Anything contained
herein to the contrary notwithstanding, no Assignee shall be obligated to
perform any duty, covenant or condition required to be performed by the Lessor
hereunder, and any such duty, covenant or condition shall be and remain the sole
obligation of the Lessor.

                  SECTION 22. INCOME TAXES.

                  (a) The Lessor agrees that it will not file any Federal, state
or local income tax returns during the Lease Term with respect to any Property
or Equipment that are inconsistent with the treatment of the Lessee as tax owner
of such Property or Equipment for Federal, state and local income tax purposes.

                  (b) Paragraph (a) of Section 22 above notwithstanding, the
Lessor agrees that, at the written request of the Lessee, it will take all such
action as may be required to be taken by a lessor to elect under any provision
of the Code substantially similar to section 48(d) of the Internal Revenue Code
of 1954, as amended prior to the enactment of the Tax Reform Act of 1986,
permitting a pass-through of an investment tax credit to a lessee, to treat the
Lessee as having acquired any Unit of Equipment or any qualifying appliances,
equipment and machinery attached to any Parcel of Property acquired by the
Lessor that would qualify for such a credit (within the meaning of section 48(b)
of the Code); provided, that such request is received by the Lessor reasonably
in advance of the date on which the Lessor is required to take such action, and
the Lessee provides the Lessor in a timely fashion with all information (other
than identifying information pertaining to the Lessor) required to take such
action. The Lessor does not represent or warrant to the Lessee that credits will
be allowable with respect to any Unit of Equipment or other property under the
Code or that any election will be effective to transfer any such credits that
are allowable to the Lessee. The Lessor shall have no liability to the Lessee
resulting from the disallowance to the Lessee of credits under the Code with
respect to any Unit of Equipment or other property unless such disallowance is
directly and primarily attributable to the failure of the Lessor to comply with
its obligations under the first sentence of this paragraph (b).

                  SECTION 23. NOTICES AND REQUESTS.

                  All notices, offers, acceptances, approvals, waivers,
requests, demands and other communications hereunder or under any other
instrument, certificate or other document delivered in connection with the
transactions described herein shall be in writing, shall be addressed as

Federal Express, Emery, DHL, Airborne Express, and other similar express
delivery services), (c) in the event overnight delivery services are not readily
available, if mailed by international airmail, postage prepaid, registered or
certified with return receipt requested, or (d) if sent by telecopy and
confirmed; provided, that in the case of a notice by telecopy, the sender shall
in addition confirm such notice by writing sent in the manner specified in
clauses (a), (b) or (c) of this Section 23. All notices shall be effective upon
receipt by the addressee; provided, however, that if any notice is tendered to
an addressee and the delivery thereof is refused by such addressee, such notice
shall be effective upon such tender. For the purposes of notice, the addresses
of the parties shall be as set forth below; provided, however, that any party
shall have the right to change its address for notice hereunder to any other
location

claiming through or under the Lessor.

                                                    CONFIDENTIAL AND PROPRIETARY


                  SECTION 25. RIGHT TO PERFORM FOR LESSEE.

                  (a) If the Lessee fails to perform or comply with any of its
covenants or agreements contained in this Lease, the Lessor may, upon reasonable
notice to the Lessee but without waiving or releasing any obligations or
default, itself perform or comply with such covenant or agreement, and the
amount of the reasonable expenses of the Lessor incurred in connection with such
performance or compliance, shall be payable by the Lessee, not later than
fifteen (15) days after written notice by the Lessor.

                  (b) Without in any way limiting the obligations of the Lessee
hereunder, the Lessee hereby irrevocably appoints the Lessor as its agent and
attorney at the time at which the Lessee is obligated to deliver possession of
any Parcel of Property or Unit of Equipment to the Lessor, to demand and take
possession of such Parcel of Property or Unit of Equipment in the name and on
behalf of the Lessee from whomsoever shall be at the time in possession thereof.

                  SECTION 26. MERGER, CONSOLIDATION OR SALE OF ASSETS.

                  Except as provided in paragraph (o) of Section 29 of this
Lease, the Lessee may not consolidate with or merge into any other corporation
or sell or assign all or substantially all of its assets or its interest in the
Ammonia Project to any Person, unless the surviving corporation or transferee
Person shall assume, by execution and delivery of instruments satisfactory to
the Lessor prior to any such consolidation, merger, sale or assignment, the
obligations of the Lessee hereunder and become successor to the Lessee, but the
Lessee shall not thereby be released, without the consent of the Lessor, from
its obligations hereunder and; provided, further, that no Event of Default shall
have occurred and be continuing, both prior and after giving effect to any such
consolidation, merger, sale or assignment and such surviving corporation or
transferee Person will, on a pro forma basis, immediately after such
consolidation, merger or sale, possess a consolidated net worth and credit
rating substantially equivalent to or greater than that of the Lessee
immediately prior to such consolidation, merger or sale. The terms and
provisions of this Lease shall be binding upon and inure to the benefit of the
Lessee and its respective successors and assigns.

                  SECTION 27. PERMITTED CONTESTS.

                  (a) The Lessee shall not be required, nor shall the Lessor
have the right, to pay, discharge or remove any tax, assessment, levy, fee,
rent, charge or Lien, or to comply or cause any Parcel of Property or Unit of
Equipment to comply with any Legal Requirements applicable to any Parcel of
Property or Unit of Equipment or the occupancy, use or operation thereof, so
long as no Event of Default exists under this Lease with respect to any Parcel
of Property or Unit of Equipment, and, in the judgment of the Lessee's counsel,
the Lessee shall have reasonable grounds to contest the existence, amount,
applicability or validity thereof by appropriate proceedings, which proceedings
in the reasonable judgment of the Lessor, (i) shall not involve any material
danger that any Parcel of Property or Unit of Equipment or any Basic Rent or any
Additional Rent would be subject to sale, forfeiture or loss or loss of use as a
result of failure to comply therewith, (ii) shall not affect the payment of any
Basic Rent or any Additional Rent or other sums due and payable hereunder or
result in any such sums being payable to any Person other than the Lessor or any
Assignee, (iii) will not place the Lessor in any danger of any monetary civil
liability for which the Lessor is not adequately indemnified (the Lessee's
obligations under Section 11 of this Lease shall be deemed to be adequate
indemnification if no Event of Default exists) or any other material

civil penalty, or to any criminal liability, (iv) if involving taxes, shall
suspend the collection of taxes, and (v) shall be permitted under and be
conducted in accordance with the provisions of any other instrument to which the
Lessee or the Parcel of Property or Unit of Equipment is subject and shall not
constitute a default thereunder (the "Permitted Contest"). The Lessee shall
conduct all Permitted Contests in good faith and with due diligence and shall
promptly after the final determination (including appeals) of any Permitted
Contest pay and discharge all amounts which shall be determined to be payable
therein. The Lessor shall at the Lessee's expense cooperate in good faith with
the Lessee with respect to all Permitted Contests conducted by the Lessee
pursuant to this Section 27, including, without limitation, in assisting in the
preparation of, and participating in, filings related to such Permitted
Contests.

                  (b) At least ten (10) days prior to the commencement of any
Permitted Contest, the Lessee shall notify the Lessor in writing thereof if the
amount in contest exceeds $1,000,000 and shall describe such proceeding in
reasonable detail. In the event that a taxing authority or subdivision thereof
proposes an additional assessment or levy of any tax for which the Lessee is
obligated to reimburse the Lessor under this Lease, or in the event that the
Lessor is notified of the commencement of an audit or similar proceeding which
could result in such an additional assessment, then the Lessor shall in a timely
manner notify the Lessee in writing of such proposed levy or proceeding.

                  (c) The Lessor and the Lessee agree that no Event of Default
or Potential Default shall be deemed to have occurred if the existence of the
event causing such Event of Default or Potential Default, as the case may be, is
being contested by the Lessee as a Permitted Contest in accordance with the
terms of this Section 27.

                  SECTION 28. LEASEHOLD INTERESTS.

                  The following provisions relate to the Site Lease, the
Sublease and each additional lease under which a leasehold interest in a Parcel
of Property is subleased to the Lessee or a Permitted Sublessee hereunder (each,
a "Ground Lease"):

                  (a) The Lessee hereunder covenants and agrees to perform and
to observe and to cause each Permitted Sublessee to perform and observe all of
the terms, covenants, provisions, conditions and agreements of the underlying
Ground Leases on the Lessor's part as lessee or sublessee thereunder to be
performed and observed (including, without limitation, payment of all rent,
additional rent and other amounts payable by the Lessor as lessee under any
Ground Lease) to the end that all things shall be done which are necessary to
keep unimpaired the rights of the Lessor as lessee under any Ground Lease. The
Lessee further covenants that it shall cause to be exercised any renewal option
contained in the Ground Lease which relates to renewal occurring in whole or in
part during the term of this Lease. The Lessee agrees to cooperate fully with
the Lessor to enforce the Lessor's rights as the lessee under any Ground Lease
as against the lessor under such Ground Lease.

                  (b) The Lessee covenants and agrees pursuant to Section 11
hereof to indemnify and hold harmless the Lessor and any Assignee from and
against any and all liability, loss, damage, suits, penalties, claims and
demands of every kind and nature (including, without limitation, reasonable
attorneys' fees and expenses) by reason of the Lessee's or any Permitted
Sublessee's failure to comply with any Ground Lease or the provisions of this
Section 28.

                                                    CONFIDENTIAL AND PROPRIETARY


                  (c) The Lessor and the Lessee agree that the Lessor shall have
no obligation or responsibility to provide services or equipment required to be
provided or repairs or restorations required to be made in accordance with the
provisions of any Ground Lease by the lessor thereunder. The Lessor shall in no
event be liable to the Lessee nor shall the obligations of the Lessee hereunder
be impaired or the performance thereof excused because of any failure or delay
on the part of the lessor under any Ground Lease in providing such services or
equipment or making such restorations or repairs and such failure or delay shall
not constitute a basis for any claim against the Lessor or any offset against
any amount payable to the Lessor under this Lease.

                  (d) The Lessor's interest under any Ground Lease shall not
expire, terminate or otherwise be extinguished without the prior written consent
of the Lessor.

                  (e) The Lessee shall ensure that the Site Lease and the
Sublease shall each be a Mortgageable Ground Lease.

                  SECTION 29. MISCELLANEOUS.

                  (a) All indemnities, representations and warranties, and the
obligation to pay Additional Rent contained in this Lease shall survive the
expiration or other termination hereof.

                  (b) This Lease, the Unit Leasing Records and the AFL Unit
Leasing Records covering Property or Equipment leased pursuant hereto, the other
Operative Documents and the instruments, documents or agreements referred to
herein and therein constitute the entire agreement between the parties and no
representations, warranties, promises, guarantees or agreements, oral or
written, express or implied, have been made by any party hereto with respect to
this Lease or the Property or Equipment, except as provided herein or therein.

                  (c) This Lease may not be amended, modified or terminated, nor
may any obligation hereunder be waived orally, and no such amendment,
modification, termination or waiver shall be effective for any purpose unless it
is in writing, signed by the party against whom enforcement thereof is sought. A
waiver on one occasion shall not be construed to be a waiver with respect to any
other occasion.

                  (d) The captions in this Lease are for convenience of
reference only and shall not be deemed to affect the meaning or construction of
any of the provisions hereof. Any provision of this Lease which is prohibited by
law or unenforceable in any jurisdiction shall, as to such jurisdiction, be
ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and the parties hereto shall
negotiate in good faith appropriate modifications to reflect such changes as may
be required by law, and, as nearly as possible, to produce the same economic,
financial and tax effects as the provision which is prohibited or unenforceable;
and any such prohibition or unenforceability in any jurisdiction shall not
invalidate or render unenforceable such provision in any other jurisdiction. To
the extent permitted by applicable law, the Lessee and the Lessor hereby waive
any provision of law which renders any provision hereof prohibited or
unenforceable in any respect. THIS LEASE HAS BEEN EXECUTED AND DELIVERED IN THE
STATE OF NEW YORK. THE LESSEE AND THE LESSOR AGREE THAT, TO THE MAXIMUM EXTENT
PERMITTED BY THE LAW OF THE STATE OF NEW YORK, THIS LEASE, AND THE RIGHTS AND
DUTIES OF THE LESSEE AND THE LESSOR HEREUNDER, SHALL BE GOVERNED BY, AND
CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK (INCLUDING

                  (h) The Lessee and the Lessor agree to treat information
concerning the structure and documentation of the Agreement for Lease and this
Lease confidentially, except to the extent that disclosure is required by law
(in which circumstance such party will use reasonable efforts to notify the
other party prior to such disclosure of any information). The foregoing
constraint shall not include information: (i) that is now in the public domain
or subsequently enters the public domain without fault on the part of the party
proposing to disclose the same; (ii) currently known to the Lessee or the Lessor
from its own sources as evidenced by its prior written records; (iii) that the
Lessee or the Lessor receives from a third party not under any obligation to
keep such information confidential or (iv) that is provided by Lessee or Lessor
to counsel, consultants, other advisors and regulatory authorities, or lenders
under the Revolving Loan Facility, and Assignees or proposed Assignees, provided
such parties agree (including in writing if so requested by the non-providing
party) to treat any information so provided as similarly confidential.

                  (i) The Lessor recognizes the Lessee's right to call any
Property by such name or designation as the Lessee may deem appropriate or
reliable in the ordinary course of the Lessee's business and to place such
signs, labels, plates or other markings on any Property or Equipment as the
Lessee may desire in exercising such rights, subject to the provisions of
paragraph (b) of Section 8 hereof.

                  (j) The Lessor shall provide to Lessee on the date hereof and
hereafter upon the reasonable request of the Lessee, a balance sheet of the
Lessor certified by the Lessor and showing that the Lessor's capitalization is
such that at least 3.9% of its capitalization consists of contributions from the
Lessor's general partner and limited partners.

                  (k) In connection with the sale of any Property or Equipment
pursuant to the provisions of this Lease or the Purchase Option, the Lessor
shall convey, and the purchaser shall accept a conveyance of, the Lessor's
interest in the Operating Agreement, the Gas Contract, all easements, licenses,
Ground Leases, Ancillary Facility Agreements and similar agreements for the
benefit of such Property, adjacent property or Equipment, such conveyance to be
without warranty by, or recourse to, the Lessor, except that such interest shall
be free of any Liens resulting from the Lessor's willful or knowing act or
omission unrelated to an occurrence of an Event of Default.

                  (l) Upon the occurrence of an Event of Default and upon the
written request of the Lessee, which shall be received by the Lessor and any
Assignee not later than fifteen (15) Business Days subsequent to receipt by the
Lessee of notice (an "Event of Default Notice") from the Lessor or any Assignee
pursuant to this Lease that an Event of Default has occurred, the Lessee shall
have the right but not the obligation, not later than thirty (30) Business Days
after the Lessee received the notice of the Event of Default from the Lessor or
any Assignee, to purchase all Property and Equipment at a price equal to the
Acquisition Cost for such Property and Equipment; provided that the purchase
option contained in this paragraph shall not be available to the Lessee if the
purchase price and all other amounts paid by the Lessee would in the
circumstances in which such payment is made constitute a preferential payment or
a voidable transfer pursuant to the provisions of the Federal Bankruptcy Code in
a bankruptcy proceeding by or against the Lessee or would otherwise result in
the payment being subject to recapture from the Lessor. In connection with, and
as a condition to, the purchase of any Property and Equipment pursuant hereto,
(i) the Lessee shall pay at the time of purchase, in addition to the Acquisition
Cost of the Property and Equipment, all other amounts payable by the Lessee

similar taxes, fees, expenses and closing costs (including reasonable attorneys'
fees) in connection with the conveyance of such Property and Equipment to the

title, such transfer shall be on an as-is, non-installment sale basis, without
warranty by, or recourse to, the Lessor, except that such title shall be free of
any Liens resulting from the Lessor's willful or knowing act or omission.

                  (m) Notwithstanding any provision of this Lease to the
contrary, for purposes of any Parcel of Property for which Substantial

Lease, and the provisions of the first sentence of paragraph (a) of Section 8 of

Lease, paragraph (g) of Section 9 of this Lease and clause (i) of paragraph (c)
of Section 10 of this Lease shall not be applicable to such Parcel.

Assignment Agreement and Consent, the Lessor hereby assigns to the Lessee all of
the Lessor's right, title and interest in, to and under the Gas Contract, the
Operating Agreement and each Ancillary Facility Agreement from the date hereof
until the termination of the Initial Term and the Renewal Term, if any, with
respect to the Ammonia Project.

                  (o) Upon obtaining the prior written consent of the Lessor,
which consent shall not be unreasonably withheld or denied, the Lessee shall not
be obligated to preserve its status as a partnership not taxable as a
corporation, and the Lessee shall be permitted to change its status as a
partnership.

construed to limit the exercise or enforcement, in accordance with the terms of
this Lease and the Operative Documents and any other documents referred to
herein, of rights and remedies against the limited partnership or the corporate
general partner of the Lessor or the assets of the limited partnership or the
corporate general partner of the Lessor.

                         Description of OSHA Litigation

              In January 1993, OSHA issued citations to the Lessee and proposed
a total civil penalty of $5.1 million as a result of the failure of the urea
unit at the Lake Charles plant in 1992.  In December 1993, the judge in the
ensuing administrative law proceeding reduced the proposed penalty for the
principal citation from $4.4 million to $50,000 in granting the Lessee's motion
for partial summary judgment and severance.  OSHA has appealed this decision to
the Occupational Safety and Health Review Commission ("Review Commission"), and
on September 15, 1995, the Review Commission affirmed the judge's decision.
The Review Commission also remanded the case to the judge and ordered the
consolidation of the previously severed citations in order to allow OSHA to
seek the judge's permission to amend the citation.  OSHA chose not to seek an
amendment, and the judge again severed the citations.  OSHA has again appealed
the decision reducing the penalty to the Review Commission as a procedural
prerequisite to seeking judicial review of the decision in the United States
Court of Appeals.  In the meantime, the trial on the merits of the underlying
citation has been concluded, but a decision is not expected for several months.

              In October 1994, the Lessee paid $.4 million to OSHA to settle
the remaining citations.  The Lessee did not admit to violating any law,
regulation or safety standard and entered into the partial settlement solely to
avoid the substantial cost and burden of litigating these issues.  The Lessee
maintains that it operated the Lake Charles plant in accordance with applicable
health and safety regulations and industry standards, and continues to believe
emphatically that OSHA's claims are without merit.

              While management and legal counsel believe that any civil penalty
ultimately paid by the Lessee will be substantially less than the remaining
$4.4 million penalty proposed by OSHA, they cannot predict with certainty the
outcome of this proceeding.

              The Lessee received a large number of claims for personal injury
and property damage as a result of the Lake Charles incident.  Most of the
claims were settled through a claims adjuster retained by the Lessee and its
liability insurance carriers.  A number of suits arising from the incident also
were filed against the Lessee.  There are currently 11 suits pending in the
United States District Court for the Western District of Louisiana, Lake
Charles Division, which have been consolidated for joint administration, and 13
cases (including one suit that has been certified as a class action) pending in
the 14th Judicial District Court of Calcasieu Parish, Louisiana, which also
have been consolidated for joint administration.  The plaintiffs in these suits
generally are seeking damages for alleged physical, mental and emotional
suffering and other personal injuries, and/or property damage, lost earnings
and other economic losses as a result of the failure.  Most of the suits also
include claims for punitive damages.  All but three of the suits are being
defended by the Lessee's liability insurance carriers on its behalf, and the
damages alleged in such suits are believed to be within the maximum coverage
limit of the liability insurance.  The remaining three actions, in which the
plaintiffs are substantially identical and assert substantially the same claims
of economic and other injuries, are being defended by the Lessee and may not be
covered by its liability insurance.  The Lessee believes that many of the
unsettled claims and the suits are frivolous and/or insubstantial and is
vigorously defending against the same.

                    DESCRIPTION OF THE PROPERTY TO BE LEASED



Ammonia Plant Project

     The project is to build at the existing Arcadian complex in Trinidad a
1,850 metric tonne per day ("MTPD") ammonia plant.  Ammonia will be produced as
refrigerated product going to the new atmospheric refrigerated storage tankage.
The plant will be operated by Arcadian Trinidad Limited (ATL) and will be
engineered, procured, and constructed by The M. W. Kellogg Company ("MWK').

     The project will utilize MWKs 1,850 MTPD ammonia process based on the low
energy natural gas reforming process offered and licensed by MWK.

     The ammonia plant will be designed to produce 1,850 MTPD ammonia at -28
degrees F for storage in non-pressurized tanks.  Processing steps consist of
the following:

     1.    Raw Synthesis Gas Preparation - Raw synthesis gas is produced from
           natural gas as follows: compression, preheating and desulfurization
           is followed by steam reforming of the hydrocarbons in the natural
           gas in the primary reformer furnace.  Auto thermal reforming in the
           secondary reformer where the remainder of the natural gas is
           converted to hydrogen, carbon monoxide and carbon dioxide while
           introducing sufficient process air to provide the nitrogen required
           for ammonia synthesis.  The carbon
<PAGE>   68
           monoxide is further reformed to carbon dioxide and hydrogen in shift
           reactor utilizing steam.

     2.    Synthesis Gas Purification - In this section, the raw synthesis gas
           is processed to remove carbon dioxide and carbon monoxide yielding a
           highly pure hydrogen-nitrogen rich synthesis gas.  The carbon
           dioxide removal is accomplished by use of an improved Benfield
           Low-Heat process (licensed by VOP).  Final removal of residual
           carbon dioxide and carbon monoxide is accomplished by methanation.

     3.    Purified Synthesis Gas Compression and Ammonia Synthesis - The above
           gas along with a recycled hydrogen stream is then compressed in a
           single case centrifugal compressor, a recycle wheel also compresses
           the loop circulating gases.  The combined gases are then preheated
           before going to the ammonia reactor for conversion to ammonia.
           After heat recovery, the reactor effluent is cooled with cooling
           water and then ammonia refrigerant to condense the ammonia from the
           gases.  The liquid ammonia formed is depressurized and sent to
           refrigerated ammonia storage.

     The plant will contain a new control room and motor control center located
at its battery limits.  No new administration buildings or offices will be
required.  There will be no changes to the existing urea facility or the ship
loading dock.
<PAGE>   69
     All normal plant utilities, including fresh water, potable water, cooling
water, main and emergency power, and fire water will be provided as part of
this project.  Such services will also involve an operating agreement with ATL.

<PAGE>   77
              Amendment No. 1 dated as of August 26, 1996 to Lease Agreement
("Amendment No. 1"), dated as of March 27, 1996, between Nitrogen Leasing
Company, Limited Partnership, a Delaware limited partnership ("Lessor"), and
Arcadian Fertilizer, L.P., a Delaware limited partnership ("Lessee"), amending
the Lease Agreement referred to below.

              WHEREAS,  Lessor and Lessee have heretofore entered into an Lease
Agreement, dated as of March 27, 1996 (the "Lease Agreement"); and

              WHEREAS, Lessor and Lessee wish to amend the Lease Agreement as
hereinafter provided;

              NOW, THEREFORE, Lessor and Lessee hereby agree that the Lease
Agreement is amended as follows:

              1.     Section 1 of the Lease Agreement is hereby amended by
                     adding the following definition thereto:

                     "'Appraisal Procedure' means the following procedure
              whereby an independent appraiser shall be appointed by the Lessor
              and the Lessee, with the consent of the Assignee, to determine
              the amount, if any, by which the sales price of the Ammonia
              Project has been reduced as the direct result of wear and tear in
              excess of the wear and tear that would have occurred if the
              Lessee's obligations contained in the second sentence of
              paragraph (b) of Section 9 of this Lease had been satisfied, if
              such determination is required under Section 19 of this Lease.
              If no such appraiser is appointed by the Lessor and the Lessee
              within thirty (30) days after the written request of either the
              Lessor or the Lessee that an appraiser be appointed, the Lessor
              and the Lessee shall each appoint an independent appraiser within
              thirty (30) days thereafter, and the two appraisers so appointed
              shall appoint a third independent appraiser.  Each appraiser
              appointed pursuant to the foregoing procedure shall, within
              thirty (30) days after appointment of the last appraiser,
              independently determine the amount, if any, by which the sales
              price of the Ammonia Project has been reduced as the direct
              result of wear and tear in excess of the wear and tear that would
              have occurred if the Lessee's obligations contained in the second
              sentence of paragraph (b) of Section 9 of this Lease had been
              satisfied.  If the Lessor or the Lessee shall fail to appoint an
              independent appraiser within the above-mentioned thirty (30) day
              period, the appraiser appointed by the other party shall
              determine such amount.  If a single appraiser is appointed, such
              appraiser's determination shall be final.  If three appraisers
              are appointed, the amounts determined by the three appraisers
              shall be averaged, the amount which differs the most from such
              average shall be excluded, the remaining two amounts shall then
              be averaged and such average shall be final.  The expenses of all
              appraisers shall be paid by the Lessee. Each appraiser appointed
              pursuant to this "Appraisal Procedure" shall be an independent
              engineering firm of recognized standing and shall have experience
              in the construction, maintenance and operation of ammonia
              production plants."


              2.     Section 19 of the Lease Agreement is hereby amended by
adding the following paragraph (j) to such Section, to read in its entirety as
follows:





<PAGE>   78
                     "(j) If (i) an Event of Default arising solely as a result
              of the Lessee's failure to comply with its obligations contained
              in the second sentence of paragraph (b) of Section 9 of this
              Lease shall have occurred and be continuing, (ii) the Lessor
              shall terminate this Lease or the Lessee's right to the use and
              possession of the Ammonia Project, and (iii) the Lessor shall
              sell the Ammonia Project, then if the proceeds of such sale are
              less than 15.5% of the Acquisition Cost of the Ammonia Project,
              the Lessee shall pay to the Lessor the amount by which the sales
              price of the Ammonia Project has been reduced as the direct
              result of wear and tear in excess of the wear and tear that would
              have occurred if the Lessee's obligations contained in the second
              sentence of paragraph (b) of Section 9 of this Lease had been
              satisfied (the amount by which the sales price of the Ammonia
              Project has been reduced as the direct result of wear and tear in
              excess of the wear and tear that would have occurred if the
              Lessee's obligations contained in the second sentence of
              paragraph (b) of Section 9 of this Lease had been satisfied, to
              be such amount, if any, as the Lessor and the Lessee agree, or if
              no agreement is reached, the amount, if any, determined pursuant
              to the Appraisal Procedure); provided that, in no event shall the
              Lessee be required to pay an amount that, when combined with the
              proceeds received by the Lessor from the purchaser of the Ammonia
              Project, exceeds 15.5% of the Acquisition Cost of the Ammonia
              Project."


              3.   This Amendment No. 1 may be executed in several
counterparts, each of which when executed and delivered shall be deemed an
original and all of which counterparts, taken together, shall constitute but
one and the same Amendment No. 1.

              4.   This Amendment No. 1 shall in all respects be governed by,
and construed in accordance with, the laws of the State of New York, including
all matters of construction, validity and performance.

              5.   Except as provided herein, all provisions, terms and
conditions of the Lease Agreement shall remain in full force and effect.  As
amended hereby, the Lease Agreement is ratified and confirmed in all respects.

                             W I T N E S S E T H :


                 NOW, THEREFORE, in consideration of the foregoing, the
covenants and conditions hereinafter set forth, and other good and valuable
consideration, the receipt and sufficiency of which is hereby acknowledged by
each of the parties hereto, said parties hereby agree as follows:

                                   ARTICLE 1

                                PURCHASE OPTION

                 SECTION 1.01.  Exercise of Purchase Option.  Pursuant to the
terms of paragraph (a) of Section 12 of the Lease, the Lessee shall, not
earlier than 450 days and not
<PAGE>   2
later than one (1) year prior to the end of the Initial Term, request in
writing that the Owner obtain bank commitments acceptable to the Owner and the
Lessee in order to finance the Owner's ownership of the Property and Equipment
under the Lease during a Renewal Term.  Upon such request, the Owner shall
advise the Lessee and the General Partner in writing not later than 300 days
prior to the end of the Initial Term, indicating whether the Owner has been
able to obtain such binding bank commitments for a Renewal Term.  If the Owner
has advised the Lessee and the General Partner that it has been able to obtain
such binding bank commitments, the General Partner shall have the right, during
the Initial Term and during the Renewal Term, if any, upon written notice (the
"Option Notice") to the Owner and the Lessee not later than 270 days prior to
the Lease Termination Date, to purchase the Property and Equipment for the sale
price described in Section 1.02 hereof, on the date which is six (6) months
prior to the Lease Termination Date (the "Exercise Date").

                 SECTION 1.02.  Purchase Price for Property and Equipment.  The
purchase price for the Property and Equipment shall be (i) in the case of a
purchase during the Initial Term, the Acquisition Cost of the Property and
Equipment on the Exercise Date and (ii) in the case of a purchase during the
Renewal Term, the fair market value of the Property and Equipment on the
Exercise Date (the "Sale Price") and shall be payable by the General Partner to
the Owner on the Exercise Date; provided, that, the Lessee shall have no
obligation whatsoever to pay any portion of said purchase price, it being
understood that all parties hereto shall look only to the General Partner for
payment of said purchase price.  In addition to the Sale Price, the General
Partner shall pay all transfer taxes, transfer gains taxes, mortgage recording
tax, if any, recording and filing fees and all other similar taxes, fees,
expenses and closing costs (including reasonable attorneys' fees) in connection
with the conveyance of such Property or Equipment from the Owner to the General
Partner.

                 SECTION 1.03.  Transfer of Property and Equipment.  Upon
payment by the General Partner of all amounts owing to the Owner pursuant to
Section 1.02 hereof, the Owner shall transfer title to the Property and
Equipment to the General Partner by a bill of sale, quitclaim deed and such
other conveyance instruments as the General Partner may reasonably require to
convey all such Property and Equipment, which bill of sale, quitclaim deed and
other conveyance instruments shall be satisfactory in all respects to the
General Partner in its sole discretion.  The transfer of the Owner's interest
in the Property and Equipment shall be on an as-is, non-installment sale basis,
without warranty by,




                                        2
<PAGE>   3
or recourse to, the Owner, except that such title shall be free of any Liens
resulting from the Owner's willful or knowing act or omission.  Upon the sale
of the Property and Equipment, as set forth herein, the Owner's interest in the
Property and Equipment shall thereupon vest in the General Partner, free and
clear of any Lien in favor of the Owner or any Assignee.

                 SECTION 1.04.  Assignment of Contracts.  Upon payment by the
General Partner of all amounts owing to the Owner pursuant to Section 1.02
hereof, (i) the Owner shall convey, and the General Partner shall accept a
conveyance of, the Owner's interest in all contracts, easements, licenses,
operating agreements, and similar agreements relating to the construction,
equipping, use and operation of the Property and Equipment, including without
limitation the Gas Contract, the Operating Agreement and the Ancillary Facility
Agreements, (ii) the General Partner shall execute such agreements and
acknowledgements as shall in the Owner's reasonable judgment be required to
reflect such conveyance, (iii) such conveyance shall be made without warranty
by, or recourse to, the Owner, except that such interest shall be free of any
Liens resulting from the Owner's willful or knowing act or omission, and (iv)
the General Partner shall assume any and all liabilities and obligations of the
Owner, of whatever kind or nature, whether absolute or contingent, direct or
indirect, fixed or contingent, or known or unknown, arising from or based upon
any act, omission, event, condition or circumstance arising from the Property
and Equipment.

                                   ARTICLE 2

                         FAILURE OF THE GENERAL PARTNER
                                  TO PURCHASE

                 In the event the General Partner has provided written notice
to the Owner and the Lessee pursuant to Section 1.01 of this Agreement of its
intent to purchase the Property and Equipment on the date which is six (6)
months prior to the end of the Initial Term, and the General Partner fails to
effect such purchase on such date, the General Partner shall have no further
right to purchase any Property or Equipment during the Initial Term.  In the
event the General Partner has provided written notice to the Owner and the
Lessee pursuant to Section 1.01 of this Agreement of its intent to purchase the
Property and Equipment on the date which is six (6) months prior to the end of
the Renewal Term, and the General Partner fails to effect such purchase on such
date, the General Partner shall have no further right to purchase the Property
or Equipment under this Agreement.  If the General Partner has not provided
written notice to the Owner and the Lessee pursuant to Section 1.01





                                       3
<PAGE>   4
of this Agreement of its intent to purchase the Property and Equipment on the
date which is six (6) months prior to the end of the Initial Term or the
Renewal Term, as the case may be, the General Partner shall have no further
right to purchase the Property and Equipment during such Initial Term or
Renewal Term, as the case may be.

bound, or any existing applicable law, rule, regulation, license, judgment,
order or decree of any government, governmental body or court having

assign any of its rights or delegate any of its obligations hereunder without
the prior written consent of the other party hereto; provided that, the Owner
shall be permitted to assign its right, title and interest in this Agreement to
the Assignee without the prior written consent of the General Partner.

                 SECTION 4.02.  Indemnification.  The General Partner hereby
agrees to indemnify the Owner, any Assignee, any successor or successors, and
any Affiliate of each of them and their respective officers, directors,
incorporators, shareholders, partners (general and limited, including without

and servants from, and holds each of them harmless against, any and all
liabilities, taxes, losses, obligations, claims, damages, penalties, causes of
action, suits, costs and expenses





                                       6

(including, without limitation, attorneys' and accountants' fees) to which any
of them may become subject, insofar as such liabilities, taxes, losses,
obligations, claims, damages, penalties, causes of action, suits, costs and
expenses arise out of this Agreement, including without limitation the failure
of the General Partner to purchase the Property and Equipment after notice to
the Owner and the Lessee of its intent to purchase the Property and Equipment
on the Exercise Date.

                 SECTION 4.03.  Amendments and Waivers.  Any term, covenant,
agreement or condition of this Agreement may be amended, or compliance
therewith may be waived, only by an instrument or instruments in writing
executed by each of the parties hereto.  A waiver on one occasion shall not be
construed to be a waiver with respect to any other occasion.

                 SECTION 4.04.  Severability.  Any provision of this Agreement
which is prohibited or unenforceable in any jurisdiction shall be, as to such
jurisdiction, ineffective to the extent of such prohibition or unenforceability
without invalidating the remaining provisions hereof, and any such prohibition
or unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

                 SECTION 4.05.  Headings.  The headings of sections contained
in this Agreement are inserted for purposes of convenience only and shall not
be construed to affect the meaning or construction of any of the provisions
hereof.

                 SECTION 4.06.  Entire Agreement.  This Agreement sets forth
the entire agreement among the parties hereto with respect to the subject
matter hereof and no representations, warranties, promises, guaranties or
agreements, oral or written, express or implied, have been made by any party
hereto with respect to this Agreement or the Property or Equipment, except as
provided herein.

governed by, and construed and enforced in accordance with, the laws of the
State of New York.

                 SECTION 4.08.  Definitions.  Unless otherwise indicated,
capitalized terms used herein and not defined herein shall have the respective
meanings given to them in the Lease.

                 SECTION 4.09.  Counterparts.  This Agreement may be executed
in several counterparts, each of which so executed shall be deemed to be an
original; provided, that all such counterparts, taken together, shall

                 SECTION 4.10  Specific Performance.  The Owner and the General
Partner acknowledge that the Purchase Option is a unique and valuable right,
without which the parties hereto would lose substantial benefits.  The parties
hereto have concluded that, upon breach of this Agreement by any of the parties
hereto, legal remedies would be inadequate and impracticable to enforce, in
that, among other things, it would be difficult to calculate with reasonable
certainty the legal damages payable as a result of such breach; therefore, the
obligations of each of the parties hereto shall be enforceable by means of a
suit for specific performance brought by any one or more of the other parties
hereto.

                 SECTION 4.11.  WAIVER OF JURY TRIAL.  THE PARTIES HERETO
EXPRESSLY WAIVE ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR
COUNTERCLAIM RELATED TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.
THE PARTIES HERETO ACKNOWLEDGE THAT THE PROVISIONS OF THIS SECTION 4.11 HAVE
BEEN BARGAINED FOR AND THAT THEY HAVE BEEN REPRESENTED BY COUNSEL IN CONNECTION
THEREWITH.

                 SECTION   4.12.  Notices.  All notices, requests, demands and
other communications hereunder shall be governed by, and given in accordance
with and at the addresses determined pursuant to, Section 23 of the Lease.

                 SECTION 4.13.  Term.  This Agreement shall terminate upon the
earlier of (a) the expiration or termination of the Lease, or (b) the exercise
of the Purchase Option and the consummation of all transactions contemplated in
such event hereunder; provided however, that the obligations of the General
Partner contained in Section 4.02 of this Agreement shall survive the
expiration or termination of this Agreement and shall continue in full force
and effect.

                 SECTION 4.14.  Limitation of Liability.  (a)  The Owner's
obligations hereunder are intended to be the obligations of the limited
partnership and of the corporation which is the general partner thereof only
and no recourse for any obligation of the Owner hereunder, or for any claim
based thereon or otherwise in respect thereof, shall be had against any limited
partner of the Owner or any incorporator, shareholder, officer or director, or
affiliate, as such, past, present or future of such corporate general partner
or limited partner or of any successor corporation to such corporate general
partner or any corporate limited partner of the Owner, or against any direct or
indirect parent corporation of such corporate general partner or of any limited
partner of the Owner or any other subsidiary or affiliate of any such direct or
indirect parent corporation or any incorporator,





                                       8

shareholder, officer or director, as such, past, present or future, of any such
parent or other subsidiary or affiliate, it being understood that the Owner and
the general partner thereof are a limited partnership and a corporation,
respectively, formed for the purpose of the transactions involved in and
relating to this Agreement on the express understanding aforesaid.  Nothing
contained in this Section shall be construed to limit the exercise or
enforcement, in accordance with the terms of this Agreement and any other
documents referred to herein, of rights and remedies against the limited
partnership or the corporate general partner of the Owner or the assets of the
limited partnership or the corporate general partner of the Owner.

                          (b)  The General Partner's obligations hereunder are
intended to be the corporate obligations of the General Partner only and no
recourse for any obligation of the General Partner hereunder, or for any claim
based thereon or otherwise in respect thereof, shall be had against any
incorporator, shareholder, officer or director, or affiliate, as such, past,
present or future of the General Partner or of any successor corporation, or
against any direct or indirect parent corporation of the General Partner or any
other subsidiary or affiliate of any such direct or indirect parent corporation
or any incorporator, shareholder, officer or director, as such, past, present
or future, of any such parent or other subsidiary or affiliate.  Nothing
contained in this Section shall be construed to limit the exercise or
enforcement, in accordance with the terms of this Agreement and any other
documents referred to herein, of rights and remedies against the General
Partner or the assets of the General Partner.

                              EMPLOYMENT AGREEMENT


         THIS EMPLOYMENT AGREEMENT (this "Agreement") is effective as of
_________________________, 1996 (the "Effective Date"), by and between ARCADIAN
CORPORATION, a Delaware corporation (the "Company"), and _____________________
("Executive").

                             W I T N E S S E T H :

         WHEREAS, the Company is engaged in the business of producing,
marketing, selling and distributing nitrogen fertilizers and chemicals
("Business");

         WHEREAS, Executive is recognized as having experience in the
management and operation of companies that are in the Business;

         WHEREAS, the Board of Directors of the Company (the "Board") has
determined that it is in the best interests of the Company and its stockholders
to assure that the Company will have the continued dedication of Executive,
notwithstanding the possibility, threat or occurrence of a Change in Control
(as defined in Section 4.7 hereof);

         WHEREAS, the Board believes it is imperative (i) to diminish the
inevitable and significant distractions of Executive and dilution of the time
of Executive, by virtue of the personal uncertainties and risks created by a
pending or threatened Change in Control, (ii) to encourage Executive's full
attention and dedication to the Company currently and in the event of any
threatened or pending Change in Control, and (iii) to provide Executive with
compensation arrangements in the event of a Change in Control which provide
Executive with financial security, which are competitive with those of other
corporations, and which ensure that Executive receives the compensation and
benefits intended to be provided to Executive by the Company through this
Agreement and the Company's various employee benefit and compensation plans and
arrangements without regard to any Excise Tax (as defined in Section 4.11(a)
hereof); and

         WHEREAS, in order to accomplish the objectives described in the two
immediately preceding recitals, the Board desires to cause the Company to enter
into this Agreement as set forth herein.

         NOW, THEREFORE, in consideration of the premises, the mutual covenants
and agreements contained in this Agreement, and other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged,
the Company and Executive hereby agree as follows:

                                   ARTICLE I
                        EMPLOYMENT, REPORTING AND DUTIES

stated herein.

         1.2     Major Responsibilities; Authority.  Executive shall have the
authorities, duties, responsibilities and status (including offices, titles and
reporting requirements) usually associated with the Office of companies having
operations and assets similar in nature and value to the operations and assets
of the Company and at least commensurate in all material respects with the most
significant of those held, exercised and assigned at any time during the 90-day
period immediately preceding the Effective Date, and such other duties as the
Board shall determine and Executive shall accept from time to time.

         1.3     Extent of Service.  During the Term (as defined in Section
4.1), and excluding any periods of vacation and sick leave to which Executive
is entitled, Executive agrees to devote reasonable time and energies to the
Business consistent with past practice and shall not, during the Term, be
engaged in any business activity which would interfere or prevent Executive
from carrying out his duties under this Agreement; provided, however, that this
Section 1.3 shall not be construed as preventing Executive from investing his
assets in such form or manner as will not require services on the part of
Executive in the operation of the affairs of any company in which such
investments are made.

         1.4     Location.  Executive shall not be required to move from
Executive's home in Shelby County, Tennessee.

                 (a)      Base Salary.  As compensation and consideration for
         the services to be rendered by Executive under this Agreement and for
         the performance by Executive of the usual obligations of such
         employment, the Company agrees to pay Executive, and Executive agrees
         to accept, a base salary ("Base Salary") of $____________ _____ per
         annum which shall be paid in accordance with Company's standard
         payroll practice.  Executive's Base Salary may increase from time to
         time, and after any such change, Executive's new level of Base Salary
         shall be Executive's Base Salary for purposes of this Agreement until
         the effective date of any subsequent change.

                          benefit plans, programs, arrangements, and policies
                          that are generally made available by the Company and
                          its affiliates now or at any time in the future to

         2.2     Expenses.  The Company agrees that, during the Term, Executive
shall be allowed reasonable and necessary business expenses in connection with
the performance of his duties hereunder within guidelines established by the
Board as in effect at any time with respect to key employees ("Business
Expenses"), including, but not limited to, reasonable and necessary expenses
for food, travel, lodging, entertainment and other items in the promotion of
the Business within such guidelines.  The Company shall promptly reimburse
Executive for all Business Expenses incurred by Executive upon Executive's
presentation to the Company of an itemized account thereof, together with
receipts, vouchers, or other supporting documentation.  After termination or
expiration of this Agreement, however such termination or expiration may come

or expiration to submit Business Expenses incurred during the Term to the
Company for reimbursement.

proposed by Executive if Executive acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the
Company.  Executive's rights under this Article III shall not be deemed
exclusive of, but shall be cumulative with, any and all other rights

                 programs, arrangements, or policies described in Section
                 2.1(b) hereof;

         such obligations owing or accrued to, vested in, or earned by
         Executive through the date of termination, including, but not limited
         to, such amounts and benefits specified in clauses (i), (ii), and
         (iii) of this sentence, being hereinafter collectively referred to as
         the "Accrued Obligations."  The aggregate amount of such obligations
         owing or accrued to, vested in, or earned by Executive through the

         Control.  If Executive terminates this Agreement with Good Reason
         pursuant to Section 4.2(a) hereof, or if the Company terminates this

                          (1)     the Company shall pay the aggregate of the
                 following amounts to Executive in one lump sum within thirty
                 (30) days after the date of such termination or in a manner
                 and at such later time as specified by Executive, provided
                 that all such payments must be made no later than the last day
                 of the twenty-four (24) month period commencing on the date of

                                  (i)      to the extent not theretofore paid,
                          Executive's Base Salary in effect at the time of such
                          termination (but prior to giving effect to any
                          reduction therein which precipitated such
                          termination) through the date of termination; and

                                  (ii)     an amount equal to the sum of (A)
                          two (2) times Executive's Base Salary in effect at
                          the time of such termination (but prior to giving
                          effect to any reduction therein which precipitated
                          such termination), (B) two (2) times the average of
                          all bonus, profit sharing and other incentive
                          payments made by the Company to Executive in respect
                          of the two (2) calendar years immediately preceding
                          such termination, and (C) the pro-rata share of
                          Executive's target bonus, profit sharing and other
                          incentive payments for the calendar year in which
                          such termination occurred based upon the proportion
                          that the number of complete months in such calendar
                          year up to the date of termination bears to the
                          complete calendar year; and

                                  (iii)    in the case of compensation
                          previously deferred by Executive, all amounts
                          previously deferred (together with any accrued
                          interest thereon) and not yet paid by the Company,
                          and any accrued vacation pay not yet paid by the
                          Company; and

                                  (iv)     all other amounts or benefits owing
                          or accrued to, vested in, or earned by Executive
                          through the date of termination under the then
                          existing or applicable plans, programs, arrangements,
                          and policies of the Company and its affiliates,
                          including, but not limited to, any such plans,
                          programs, arrangements, or policies described in
                          Section 2.1(b) hereof; and

                                  (v)      any and all other Accrued
                          Obligations not otherwise described in clause (i),
                          (ii), (iii) or (iv) of this sentence; and

                 additional benefits:

                                  (i)      for an eighteen (18) month period
                          commencing on the date  of termination of this
                          Agreement (the "18 Month Period"), Executive shall
                          continue to be covered under each of the medical,
                          dental, life insurance, accident benefit and other
                          welfare benefit (exclusive of short- and long-term

                          and applicable to Executive immediately prior to such
                          termination, and the Company shall pay the costs
                          therefor except to the extent that Executive already
                          pays all or any portion thereof; provided however,
                          that if Executive obtains any of the welfare benefits
                          provided for under this sentence from another
                          employer, the Company's obligation to provide such
                          welfare benefits should be secondary to that of such
                          other employer.  Executive's coverage under the
                          Company's medical and dental programs for the 18
                          Month Period shall be included in the calculation of
                          the "Period of Coverage" to be provided to Executive
                          pursuant to Section 4980B(f)(2)(B) of the Internal
                          Revenue Code of 1986, as amended ("Code"), and
                          Executive's right to "Continuation Coverage" under
                          Section 4980B(f)(2) of the Code.  The amount of the
                          "Applicable Premium" to be charged Executive under
                          Section 4980B(f)(4) for Continuation Coverage shall
                          never be greater than the monthly amount charged
                          Executive for medical and dental coverage prior to
                          the termination of this Agreement; and

                                  (ii)     shall be fully vested in any and all
                          options, restricted stock, stock appreciation rights,
                          cash equivalent stock appreciation rights, or any
                          other similar rights based on the fair market value
                          of or otherwise relating to the Company's common
                          stock (collectively, "Stock Incentive Rights") which
                          are outstanding immediately prior to the termination
                          of this Agreement, and Executive may exercise any
                          such vested Stock Incentive Rights during the 24
                          Month Period, notwithstanding any provision otherwise
                          in any plan or agreement awarding or granting any
                          Stock Incentive Right to Executive; and

                                  (iii)    shall be fully vested in any and all
                          benefits accrued under any "employee pension benefit
                          plan," as defined in Section 3(2)(A) of the Employee
                          Retirement Income Security Act of 1974, as amended
                          ("ERISA"), of the Company ("Retirement Plan"); and

                                  (iv)     shall receive credit in the
                          calculation of the accrued benefit under the
                          Company's Pension Plan ("Pension Plan") for (A) the
                          compensation to be paid to Executive in clause (ii)
                          of paragraph (1) of this Section 4.3(b) and (B)
                          twenty-four (24) months of service in addition to the
                          service accrued by Executive through the date that
                          this Agreement is terminated.  If the benefits set
                          forth in this clause would cause the Pension Plan to
                          lose its qualification under Section 401(a) of the
                          Code, then the benefits accrued hereunder shall
                          accrue to Executive under the Company's Supplemental
                          Executive Retirement Plan ("SERP"); and

                                  (v)      shall receive such individual
                          outplacement service as is appropriate for
                          Executive's position for the 24 Month Period.

                 (c)      Good Reason-Change in Control; Without Cause On or
         After a Change in Control.  If Executive terminates this Agreement
         with Good Reason-Change in Control pursuant to Section 4.2(a) hereof,
         or if the Company terminates this Agreement without Cause on or after
         the occurrence of a Change in Control pursuant to Section 4.2(a)
         hereof:

                          (1)     the Company shall pay the aggregate of the
                 following amounts to Executive in one lump sum within thirty
                 (30) days after the date of such termination or in a manner
                 and at such later time as specified by Executive, provided
                 that all such payments must be made no later than the last day
                 of the thirty-six (36) month period commencing on the date of
                 such termination (the "36 Month Period"):

                                  (i)      to the extent not theretofore paid,
                          Executive's Base Salary in effect at the time of such
                          termination (but prior to giving effect to any
                          reduction therein which precipitated such
                          termination) through the date of termination; and

                                  (ii)     an amount equal to the sum of (A)
                          three (3) times Executive's Base Salary in effect at
                          the time of such termination (but prior to giving
                          effect to any reduction therein which precipitated
                          such termination), (B) three (3) times the average of
                          all bonus, profit sharing and other incentive
                          payments made by the Company to Executive in respect
                          of the two (2) calendar years immediately preceding
                          such termination, and (C) the pro-rata share of
                          Executive's target bonus, profit sharing and other
                          incentive payments for the calendar year in which
                          such termination occurred based upon the proportion
                          that the number of complete months in such calendar
                          year up to the date of termination bears to the
                          complete calendar year; and

                                  (iii)    in the case of compensation
                          previously deferred by Executive, all amounts
                          previously deferred (together with any accrued
                          interest thereon) and not yet paid by the Company,
                          and any accrued vacation pay not yet paid by the
                          Company; and

                                  (iv)     all other amounts or benefits owing
                          or accrued to, vested in, or earned by Executive
                          through the date of termination under the then
                          existing or applicable plans, programs, arrangements,
                          and policies of the Company and its affiliates,
                          including, but not limited to, any such plans,
                          programs, arrangements, or policies described in
                          Section 2.1(b) hereof; and

                                  (v)      any and all other Accrued
                          Obligations not otherwise described in clause (i),
                          (ii), (iii) or (iv) of this sentence; and

                          (2)      Executive shall receive the following 
                 additional benefits:

                                  (i)      for the 36 Month Period, Executive
                          shall continue to be covered under each of the
                          medical, dental, life insurance, accident benefit and
                          other welfare benefit (exclusive of short- and
                          long-term disability benefit) programs of the Company
                          in effect and applicable to Executive immediately
                          prior to the time of such termination, and the
                          Company shall pay the costs therefor except to the
                          extent that Executive already pays all or any portion
                          thereof; provided however, that if Executive obtains
                          any of the welfare benefits provided for under this
                          sentence from another employer, the Company's
                          obligation to provide such welfare benefits shall be
                          secondary to that of such other employer.
                          Executive's coverage under the Company's medical and
                          dental programs for the 36 Month Period shall not be
                          included in the calculation of the "Period of
                          Coverage" to be provided to Executive pursuant to
                          Section 4980B(f)(2)(B) of the Code, and Executive's
                          right to "Continuation Coverage" under Section
                          4980B(f)(2) of the Code for medical and dental
                          benefits under the Company's medical and dental
                          programs shall commence on the first day following
                          the end of the 36 Month Period.  The amount of the
                          "Applicable Premium" to be charged Executive under
                          Section 4980B(f)(4) for Continuation Coverage shall
                          never be greater than the monthly amount charged
                          Executive for medical and dental coverage during the
                          36 Month Period; and

                                  (ii)     shall be fully vested in any and all
                          benefits accrued under any Retirement Plan; and

                                  (iii)    shall receive credit in the
                          calculation of the accrued benefit under the Pension
                          Plan for (A) the compensation to be paid to Executive
                          in clause (ii) of paragraph (1) of this Section
                          4.3(c) and (B) thirty-six (36) months of service in
                          addition to the service accrued by Executive through
                          the date that this Agreement is terminated.  If the
                          benefits set forth in this clause would cause the
                          Pension Plan to lose its qualification under Section
                          401(a) of the Code, then the benefits accrued
                          hereunder shall accrue to Executive under the SERP,
                          and if the Executive is not a participant in the
                          SERP, the actuarial lump sum equivalent of the
                          benefit described in this clause (iv) shall be paid
                          in accordance with paragraph (1) of Section 4.2(c);
                          and

                                  (iv)     shall receive such individual
                          outplacement service as is appropriate for
                          Executive's position for the 36 Month Period.

                 (d)      Death.  If Executive's employment is terminated under
         Section 4.2(b) hereof by reason of Executive's death, the Company
         shall pay to Executive's legal representatives the full amount of the
         obligations owing or accrued to, vested in, or earned by Executive
         through the date of Executive's death, including, but not limited to,
         the Accrued Obligations in accordance with the plans, programs, or
         agreements under which the Accrued Obligations were earned.  Anything
         in this Agreement to the contrary notwithstanding, Executive's family
         shall be entitled to receive benefits provided by the Company and any
         of its affiliates to surviving families under the then existing or
         applicable plans, programs, or arrangements and policies of the
         Company and its affiliates.

                 (e)      Disability.  If Executive's employment is terminated
         under Section 4.2(b) hereof by reason of Executive becoming Disabled,
         the Company shall pay to Executive or Executive's legal representative
         the full amount of the obligations owing or accrued to, vested in, or
         earned by Executive through the date of termination, including, but
         not limited to, the Accrued Obligations in accordance with the plans,
         programs, or agreements under which the Accrued Obligations were
         earned.

         4.4     Cause.  As used in this Agreement, the term "Cause" means (i)
willful misconduct by Executive or gross neglect by Executive of his duties as
an employee, officer or director of the Company which continues for more than
thirty (30) days after Executive's receipt of written notice from the Board to

of Executive and directing Executive to discontinue the same, (ii) the
commission by Executive of a crime constituting a felony, or (iii) the
commission by Executive of an act, other than an act taken in good faith within

Reason" means the breach of any material provision of this Agreement by the
Company (including, but in no way limited to, any removal of Executive, without
Cause, from the position of the Office during the Term) which is not cured
within thirty (30) days after written notice from Executive to the Company
specifically identifying such breach; provided, however, that the term "Good
Reason" shall not include any breach of any provision of this Agreement that
occurs after the occurrence of a Change in Control.

         4.6     Good Reason-Change in Control.

                 (a)      Except as provided in Section 4.6(b) below, as used

         after the occurrence of a Change in Control, a determination by
         Executive that any one or more of the following events has occurred:

                          (i)     a material change in the nature of
                 Executive's Office, including, but not limited to, his

                 prior to the Change in Control; or

                          (ii)    the relocation of Executive's place of
                 employment to a location in excess of fifty (50) miles from
                 the place of Executive's employment immediately prior to the
                 Change in Control, except for required travel on Company
                 business to an extent substantially equivalent to Executive's
                 business travel obligations immediately prior to the Change in
                 Control; or

                          (iii)   any reduction by the Company of Executive's
                 Base Salary, or a material reduction in his bonus, profit
                 sharing or other incentive benefits, from those in effect
                 immediately prior to the Change in Control; or

                          (iv)    the failure by the Company to increase
                 Executive's Base Salary in a manner consistent (both as to
                 frequency and percentage increase) with (A) the Company's
                 practices in effect immediately prior to the Change in Control
                 with respect to similarly positioned employees or (B) the
                 Company's practices implemented subsequent to the Change in
                 Control with respect to similarly positioned employees,
                 whichever is more favorable to Executive; or

                 effect Executive's participation in (A) the Company's employee
                 benefit plans, programs, arrangements and policies, at a level
                 substantially equivalent in value to and on a basis consistent
                 with the relative levels of participation of other similarly
                 positioned employees, as in effect immediately prior to the
                 Change in Control or (B) the Company's employee benefit plans,
                 programs, arrangements and policies implemented subsequent to
                 the Change in Control with respect to similarly positioned
                 employees, whichever is more favorable to Executive; or

                          (vi)    the failure of the Company to obtain from a
                 successor (including a successor to a material portion of the
                 business or assets of the Company) a satisfactory assumption
                 in writing of the Company's obligations under this Agreement;
                 or

                          (vii)   the failure of the Company to continue to
                 provide Executive with office space, related facilities and
                 support personnel (including, but not limited to,
                 administrative and secretarial assistance) that are both
                 commensurate with the Office and Executive's responsibilities
                 to and position with the Company immediately prior to the
                 Change in Control and not materially dissimilar to the office
                 space, related facilities and support personnel provided to
                 other key executive officers of the Company; or

                          (viii)  the Company notifies Executive of the
                 Company's intention not to observe or perform one or more of
                 the obligations of the Company under this Agreement; or

                          (ix)    the Company breaches any provision of this
                 Agreement and such breach is not cured within thirty (30) days
                 after the Company's receipt of notice thereof from Executive.

                 (b)      If, after the occurrence of a Change in Control,
         Executive receives a written description from the Company of the
         nature of Executive's Office thereafter, stating Executive's
         authorities, duties, responsibilities, status, salary, bonus and other
         employee benefits, or job location, and Executive accepts such new
         authorities, duties, responsibilities, status, salary, bonus and other
         employee benefits, or job location ("New Office") with the Company
         without determining that the New Office causes a Good Reason-Change in
         Control as set forth in Section 4.6(a), then for the remaining Term
         the New Office shall be the authorities, duties, responsibilities,
         status, salary, bonus and other employee benefits, or job location to
         be used by Executive in determining whether a Good Reason-Change in
         Control occurs thereafter pursuant to Section 4.6(a).

         4.7     Change in Control.  As used herein, the term "Change in
Control" shall mean the occurrence with respect to the Company of any of the
following events:

                 (a)      a report on Schedule 13D is filed with the Securities
         and Exchange Commission (the "SEC") pursuant to Section 13(d) of the
         Securities Exchange Act of 1934, as amended (the "Exchange Act"),
         disclosing that any person, entity or group (within the meaning of
         Section 13(d) or 14(d) of the Exchange Act), other than the Company
         (or one of its subsidiaries) or any employee benefit plan sponsored by
         the Company (or one of its subsidiaries), is the beneficial owner (as
         such term is defined in Rule 13d-3 promulgated under the Exchange
         Act), directly or indirectly, of 30% or more of the outstanding shares
         of common stock of the Company or the combined voting power of the
         then outstanding securities of the Company;

                 (b)      a report is filed by the Company disclosing a

         promulgated under the Exchange Act, Item 1 of Form 8-K promulgated
         under the Exchange Act, or any similar reporting requirement hereafter
         promulgated by the SEC;

                 (c)      any person, entity or group (within the meaning of
         Section 13(d) or 14(d) of the Exchange Act), other than the Company
         (or one of its subsidiaries) or any employee benefit plan sponsored by
         the Company (or one of its subsidiaries), shall purchase securities
         pursuant to a tender offer or exchange offer to acquire any common
         stock of the Company (or securities convertible into common stock) for
         cash, securities or any other consideration, provided that after
         consummation of the offer, the person, entity or group in question is
         the beneficial owner (as such term is defined in Rule 13d-3
         promulgated under the Exchange Act), directly or indirectly, of 30% or
         more of the combined voting power of the then outstanding securities

         promulgated under the Exchange Act, in the case of rights to acquire
         common stock);

                 (d)      the stockholders of the Company shall approve:

                                  (A)      in which the Company is not the
                          continuing or surviving corporation,

                                  (B)      pursuant to which shares of common
                          stock of the Company would be converted into cash,

                                  (C)      with a corporation which prior to
                          such merger, consolidation, or reorganization owned
                          20% or more of the combined voting power of the then
                          outstanding securities of the Company, or

                                  (D)      in which the Company will not

                 Company;

                 (e)      the stockholders of the Company shall approve a
         merger, consolidation, reorganization, recapitalization, exchange
         offer, purchase of assets or other transaction after the consummation
         of which any person, entity or group (within the meaning of Section
         13(d) or 14(d) of the Exchange Act) would own beneficially in excess
         of 30% of the outstanding shares of common stock of the Company or in
         excess of 30% of the combined voting power of the then outstanding
         securities of the Company;

                 (f)      the Company's common stock ceases to be listed on the
         New York Stock Exchange; or

                 (g)      during any period of two consecutive years, the
         individuals who at the beginning of such period constituted the Board
         cease for any reason to constitute a majority of the Board, unless the
         election or nomination for election by the Company's stockholders of
         each new director during any such two-year period was approved by the
         vote of two-thirds of the directors then still in office who were

         4.9     Disabled.  As used herein, "Disabled" shall mean a mental or
physical impairment which, in the reasonable opinion of a qualified doctor
selected by the Company, renders Executive unable to perform with reasonable
diligence the ordinary functions and duties of Executive on a





                                      -12-

full-time basis in accordance with the terms of this Agreement, which inability
continues for a period of not less than 180 consecutive days.

         4.10    Return of Materials; Confidential Information.  In the event
of any termination of this Agreement, Executive shall promptly deliver to the
Company all lists, books, records, literature, products and any other materials
owned or provided by the Company in connection with Executive's employment
hereunder.  Executive shall not at any time during or after the Term hereof use
for himself or others, or divulge to others, any secret or confidential
information, knowledge or data of the Company obtained by Executive as a result
of his employment unless authorized by a majority of the Board.

         4.11    Certain Additional Payments by the Company.

                 (a)      Anything in this Agreement to the contrary
notwithstanding, in the event it shall be determined that any payment or
distribution by the Company  or any of its affiliates to or for the benefit of
Executive, whether paid or payable or distributed or distributable pursuant to
the terms of this Agreement or otherwise (any such payments or distributions
being individually referred to herein as a "Payment," and any two or more of
such payments or distributions being referred to herein as "Payments"), would
be subject to the excise tax imposed by Section 4999 of the Code (such excise
tax, together with any interest thereon, any penalties, additions to tax, or
additional amounts with respect to such excise tax, and any interest in respect
of such penalties, additions to tax or additional amounts, being collectively
referred herein to as the "Excise Tax"), then Executive shall be entitled to
receive and the Company shall make an additional payment or payments
(individually referred to herein as a "Gross-Up Payment," and any two or more
of such additional payments being referred to herein as "Gross-Up Payments") in
an amount such that after payment by Executive of all taxes (as defined in
Section 4.11(k)) imposed upon the Gross-Up Payment, Executive retains an amount
of such Gross-Up Payment equal to the Excise Tax imposed upon the Payments.

                 (b)      Subject to the provisions of Section 4.11(c) through
(i), any determination (individually, a "Determination") required to be made
under this Section 4.11(b), including whether a Gross-Up Payment is required
and the amount of such Gross-Up Payment, shall initially be made, at the
Company's expense, by nationally recognized tax counsel mutually acceptable to
the Company and Executive ("Tax Counsel").  Tax Counsel shall provide detailed
supporting legal authorities, calculations, and documentation both to the
Company and Executive within 15 business days of the termination of Executive's
employment, if applicable, or such other time or times as is reasonably
requested by the Company or Executive.  If Tax Counsel makes the initial
Determination that no Excise Tax is payable by Executive with respect to a
Payment or Payments, it shall furnish Executive with an opinion reasonably
acceptable to Executive that no Excise Tax will be imposed with respect to any
such Payment or Payments.  Executive shall have the right to dispute any
Determination (a "Dispute") within 15 business days after delivery of Tax
Counsel's opinion with respect to such Determination.  The Gross-Up Payment, if
any, as determined pursuant to such Determination shall, at the Company's
expense, be paid by the Company to Executive within five business days of
Executive's receipt of such Determination.  The existence of a Dispute shall
not in any way affect Executive's right to receive the Gross-Up Payment in
accordance with such Determination.  If there is no Dispute, such Determination
shall be binding, final and conclusive upon the Company and





                                      -13-

Executive, subject in all respects, however, to the provisions of Section
4.11(c) through (i) below.  As a result of the uncertainty in the application
of Sections 4999 and 280G of the Code, it is possible that Gross-Up Payments
(or portions thereof) which will not have been made by the Company should have
been made ("Underpayment"), and if upon any reasonable written request from
Executive or the Company to Tax Counsel, or upon Tax Counsel's own initiative,
Tax Counsel, at the Company's expense, thereafter determines that Executive is
required to make a payment of any Excise Tax or any additional Excise Tax, as
the case may be, Tax Counsel shall, at the Company's expense, determine the
amount of the Underpayment that has occurred and any such Underpayment shall be
promptly paid by the Company to Executive.

                 (c)      The Company shall defend, hold harmless, and
indemnify Executive on a fully grossed-up after tax basis from and against any
and all claims, losses, liabilities, obligations, damages, impositions,
assessments, demands, judgements, settlements, costs and expenses (including
reasonable attorneys', accountants', and experts' fees and expenses) with
respect to any tax liability of Executive resulting from any Final
Determination (as defined in Section 4.11(j)) that any Payment is subject to
the Excise Tax.

                 (d)      If a party hereto receives any written or oral
communication with respect to any question, adjustment, assessment or pending
or threatened audit, examination, investigation or administrative, court or
other proceeding which, if pursued successfully, could result in or give rise
to a claim by Executive against the Company under this Section 4.11(d)
("Claim"), including, but not limited to, a claim for indemnification of
Executive by the Company under Section 4.11(c), then such party shall promptly
notify the other party hereto in writing of such Claim ("Tax Claim Notice").

                 (e)      If a Claim is asserted against Executive ("Executive
Claim"), Executive shall take or cause to be taken such action in connection
with contesting such Executive Claim as the Company shall reasonably request in
writing from time to time, including the retention of counsel and experts as
are reasonably designated by the Company (it being understood and agreed by the
parties hereto that the terms of any such retention shall expressly provide
that the Company shall be solely responsible for the payment of any and all
fees and disbursements of such counsel and any experts) and the execution of
powers of attorney, provided that:

                          (i)     within 30 calendar days after the Company
         receives or delivers, as the case may be, the Tax Claim Notice
         relating to such Executive Claim (or such earlier date that any
         payment of the taxes claimed is due from Executive, but in no event
         sooner than five calendar days after the Company receives or delivers
         such Tax Claim Notice), the Company shall have notified Executive in
         writing ("Election Notice") that the Company does not dispute its
         obligations (including, but not limited to, its indemnity obligations)
         under this Agreement and that the Company elects to contest, and to
         control the defense or prosecution of, such Executive Claim at the
         Company's sole risk and sole cost and expense; and

                          (ii)    the Company shall have advanced to Executive
         on an interest-free basis, the total amount of the tax claimed in
         order for Executive, at the Company's request, to pay or cause to be
         paid the tax claimed, file a claim for refund of such tax and, subject
         to the provisions of the last sentence of Section 4.11(g), sue for a
         refund of such tax if such





                                      -14-
<PAGE>   15
         claim for refund is disallowed by the appropriate taxing authority (it
         being understood and agreed by the parties hereto that the Company
         shall only be entitled to sue for a refund and the Company shall not
         be entitled to initiate any proceeding in, for example, United States
         Tax Court) and shall indemnify and hold Executive harmless, on a fully
         grossed-up after tax basis, from any tax imposed with respect to such
         advance or with respect to any imputed income with respect to such
         advance; and

                          (iii)   the Company shall reimburse Executive for any
         and all costs and expenses resulting from any such request by the
         Company and shall indemnify and hold Executive harmless, on fully
         grossed-up after-tax basis, from any tax imposed as a result of such
         reimbursement.

                 (f)      Subject to the provisions of Section 4.11(e) hereof,
the Company shall have the right to defend or prosecute, at the sole cost,
expense and risk of the Company, such Executive Claim by all appropriate
proceedings, which proceedings shall be defended or prosecuted diligently by
the Company to a Final Determination; provided, however, that (i) the Company
shall not, without Executive's prior written consent, enter into any compromise
or settlement of such Executive Claim that would adversely affect Executive,
(ii) any request from the Company to Executive regarding any extension of the
statute of limitations relating to assessment, payment, or collection of taxes
for the taxable year of Executive with respect to which the contested issues
involved in, and amount of, the Executive Claim relate is limited solely to
such contested issues and amount, and (iii) the Company's control of any
contest or proceeding shall be limited to issues with respect to the Executive
Claim and Executive shall be entitled to settle or contest, in his sole and
absolute discretion, any other issue raised by the Internal Revenue Service or
any other taxing authority.  So long as the Company is diligently defending or
prosecuting such Executive Claim, Executive shall provide or cause to be
provided to the Company any information reasonably requested by the Company
that relates to such Executive Claim, and shall otherwise cooperate with the
Company and its representatives in good faith in order to contest effectively
such Executive Claim.  The Company shall keep Executive informed of all
developments and events relating to any such Executive Claim (including,
without limitation, providing to Executive copies of all written materials
pertaining to any such Executive Claim), and Executive or his authorized
representatives shall be entitled, at Executive's expense, to participate in
all conferences, meetings and proceedings relating to any such Executive Claim.

                 (g)      If, after actual receipt by Executive of an amount of
a tax claimed (pursuant to an Executive Claim) that has been advanced by the
Company pursuant to Section 4.11(e)(ii) hereof, the extent of the liability of
the Company hereunder with respect to such tax claimed has been established by
a Final Determination, Executive shall promptly pay or cause to be paid to the
Company any refund actually received by, or actually credited to, Executive
with respect to such tax (together with any interest paid or credited thereon
by the taxing authority and any recovery of legal fees from such taxing
authority related thereto), except to the extent that any amounts are then due
and payable by the Company to Executive, whether under the provisions of this
Agreement or otherwise.  If, after the receipt by Executive of an amount
advanced by the Company pursuant to Section 4.11(e)(ii), a determination is
made by the Internal Revenue Service or other appropriate taxing authority that
Executive shall not be entitled to any refund with respect to such tax claimed
and the Company does not notify Executive in writing of its intent to contest
such denial of refund





                                      -15-
<PAGE>   16
prior to the expiration of thirty days after such determination, then such
advance shall be forgiven and shall not be required to be repaid and the amount
of such advance shall offset, to the extent thereof, the amount of any Gross-Up
Payments and other payments required to be paid hereunder.

                 (h)      With respect to any Executive Claim, if the Company
fails to deliver an Election Notice to Executive within the period provided in
Section 4.11(e)(i) hereof or, after delivery of such Election Notice, the
Company fails to comply with the provisions of Section 4.11(e)(ii) and (iii)
and (f) hereof, then Executive shall at any time thereafter have the right (but
not the obligation), at his election and in his sole and absolute discretion,
to defend or prosecute, at the sole cost, expense and risk of the Company, such
Executive Claim.  Executive shall have full control of such defense or
prosecution and such proceedings, including any settlement or compromise
thereof.  If requested by Executive, the Company shall cooperate, and shall
cause its affiliates to cooperate, in good faith with Executive and his
authorized representatives in order to contest effectively such Executive
Claim.  The Company may attend, but not participate in or control, any defense,
prosecution, settlement or compromise of any Executive Claim controlled by
Executive pursuant to this Section 4.11(h) and shall bear its own costs and
expenses with respect thereto.  In the case of any Executive Claim that is
defended or prosecuted by Executive, Executive shall, from time to time, be
entitled to current payment, on a fully grossed-up after tax basis, from the
Company with respect to costs and expenses incurred by Executive in connection
with such defense or prosecution.

                 (i)      In the case of any Executive Claim that is defended
or prosecuted to a Final Determination pursuant to the terms of this Section
4.11(i), the Company shall pay, on a fully grossed-up after tax basis, to
Executive in immediately available funds the full amount of any taxes arising
or resulting from or incurred in connection with such Executive Claim that have
not theretofore been paid by the Company to Executive, together with the costs
and expenses, on a fully grossed-up after tax basis, incurred in connection
therewith that have not theretofore been paid by the Company to Executive,
within ten calendar days after such Final Determination.  In the case of any
Executive Claim not covered by the preceding sentence, the Company shall pay,
on a fully grossed-up after tax basis, to Executive in immediately available
funds the full amount of any taxes arising or resulting from or incurred in
connection with such Executive Claim at least ten calendar days before the date
payment of such taxes is due from Executive, except where payment of such taxes
is sooner required under the provisions of this Section 4.11(i), in which case
payment of such taxes (and payment, on a fully grossed-up after tax basis, of
any costs and expenses required to be paid under this Section 4.11(i) shall be
made within the time and in the manner otherwise provided in this Section
4.11(i).

                 (j)      For purposes of this Agreement, the term "Final
Determination" shall mean (A) a decision, judgment, decree or other order by a
court or other tribunal with appropriate jurisdiction, which has become final
and non-appealable; (B) a final and binding settlement or compromise with an
administrative agency with appropriate jurisdiction, including, but not limited
to, a closing agreement under Section 7121 of the Code; (C) any disallowance of
a claim for refund or credit in respect to an overpayment of tax unless a suit
is filed on a timely basis; or (D) any final disposition by reason of the
expiration of all applicable statutes of limitations.





                                      -16-

                 (k)      For purposes of this Agreement, the terms "tax" and
"taxes" mean any and all taxes of any kind whatsoever (including, but not
limited to, any and all Excise Taxes, income taxes, and employment taxes),
together with any interest thereon, any  penalties, additions to tax, or
additional amounts with respect to such taxes and any interest in respect of
such penalties, additions to tax, or additional amounts.

                 (l)      For purposes of this Agreement, the terms "affiliate"
and "affiliates" mean, when used with respect to any entity, individual, or
other person, any other entity, individual, or other person which, directly or
indirectly, through one or more intermediaries controls, or is controlled by,
or is under common control with such entity, individual or person.  The term
"control" and derivations thereof when used in the immediately preceding
sentence means the ownership, directly or indirectly, of 50% or more of the
voting securities of an entity or other person or possessing the power to
direct or cause the direction of the management and policies of such entity or
other person, whether through the ownership of voting securities, by contract
or otherwise.

         4.12    Legal Fees and Expenses.  The Company shall defend, hold
harmless, and indemnify Executive on a fully grossed-up after tax basis from
and against any and all costs and expenses (including reasonable attorneys',
accountants' and experts' fees and expenses) incurred by Executive acting
reasonably from time to time as a result of any contest (regardless of the
outcome) by the Company or others contesting the validity or enforcement of, or
liability under, any term or provision of this Agreement, plus in each case
interest at the applicable federal rate provided for in Section 7872(f)(2)(B)
of the Code.

         4.13    Non-exclusivity of Rights.  Nothing in this Agreement shall
prevent or limit Executive's continuing or future participation in any benefit,
bonus, incentive or other plan, program, arrangement or policy provided by the
Company or any of its affiliates (including, but not limited to, any plan,
program, arrangement or policy described in Section 2.1(c) hereof) and for
which Executive and/or Executive's family may qualify, nor shall anything
herein limit or otherwise affect such rights as Executive and/or Executive's
family may have under any other agreements with the Company or any of its
affiliates.  Amounts which are vested benefits or which Executive and/or
Executive's family is otherwise entitled to receive under any plan, program,
arrangement, or policy of the Company or any of its affiliates (including, but
not limited to, any plan, program, arrangement or policy described in Section
2.1(c) hereof) at or subsequent to the date of termination of this Agreement
shall be payable in accordance with such plan, program, arrangement or policy.

         4.14    Full Settlement.  The Company's obligation to make the
payments provided for in this Agreement and otherwise to perform its
obligations hereunder shall not be affected by any set-off, counterclaim,
recoupment, defense or other claim, right or action which the Company may have
against Executive or others.  In no event shall Executive be obligated to seek

(a) For purposes of computing net income per common share, the conversion of
    12,073,108 and 2,630,952 shares of Preferred Stock for the nine months ended
    September 30, 1996 and 1995, and 9,181,790 and 7,807,065 shares of Preferred
    Stock for the three months ended September 30, 1996 and 1995, respectively,
    which are Common Stock equivalents because of the mandatory conversion
    feature, is assumed when such conversion is dilutive.
 
(b) Net income per common share -- fully diluted is set forth herein in
    accordance with Item 601 of Regulation S-K. The additional dilution arising
    in the fully diluted calculation is not material (less than 3%); therefore,
    fully diluted net income per common share is not disclosed in the statements
    of operations.
