                               PROSPECTUS SUMMARY

     The following summary is qualified in its entirety by the more detailed
information and the Financial Statements and Notes thereto appearing elsewhere,
or incorporated by reference, in this Prospectus.  Fiscal year references refer
to years ending June 30.

                                  THE COMPANY

     The Company is a major producer and supplier of nitrogen fertilizers in the
southern United States, and believes it is one of the nation's lowest-cost
nitrogen fertilizer producers.  The Company also manufactures phosphate and
potash fertilizers, making it a full product line fertilizer supplier.  The
Company sells its nitrogen and potash fertilizer products to farmers, fertilizer
dealers and distributors for ultimate use primarily in the southern farming
regions of the United States and areas served by the Mississippi River system.
The Company's phosphate fertilizers are sold primarily in international markets.

     Nitrogen, phosphorous (contained in phosphate fertilizer) and potassium
(contained in potash fertilizer) constitute the three major nutrients required
for plant growth.  Nitrogen is an essential nutrient for most plants.
Phosphorous aids in the photosynthesis process and potassium is an important
regulator of the physiological functions of plants.  These elements are all
naturally present in soil but need to be replaced through the use of fertilizers
as crops exhaust them.  There are no viable substitutes for nitrogen, phosphate
or potash fertilizers in the development and maintenance of high-yield crops.

     Nitrogen Fertilizer.  The Company produces nitrogen fertilizers at
facilities located in Yazoo City, Mississippi, and Donaldsonville, Louisiana.
In fiscal 1995, the Company sold over 1.7 million tons of nitrogen fertilizers
to farmers, fertilizer dealers and distributors located primarily in the
southern United States.  Sales of nitrogen products by the Company in fiscal
1995 were $240.7 million, which represented approximately 62% of net sales.
Nitrogen products manufactured by the Company include anhydrous ammonia,
fertilizer-grade ammonium nitrate, urea/ammonium nitrate ("UAN") solutions and
urea.  The Company is the largest U.S. manufacturer of ammonium nitrate
fertilizer, which is marketed under the trade name Amtrate(R).  Amtrate(R) has
established significant brand name recognition and a reputation as a high-
quality product.

     In December 1994, the Company signed a letter of intent with Farmland
Industries, Inc. with respect to a proposed 50-50 joint venture which would
construct and operate an approximate 700,000 tons per year anhydrous ammonia
plant to be located at La Brea, Trinidad.  The project is expected to cost
approximately $330 million, with the debt portion of such cost expected to be
financed on a non-recourse project basis.  Construction is scheduled to begin in
the first quarter of 1996 and start-up of the facility is currently scheduled
for 1998.  The Company intends to use the majority of its 50% share of the
production from the new facility primarily as a raw material for upgrading into
finished fertilizer products at its existing facilities.  Trinidad has abundant
reserves of competitively priced natural gas.  The Company expects to realize
favorable long-term operating costs based on attractive natural gas costs and
the expected production efficiencies of the new facility.

     Phosphate Fertilizer.  The Company produces diammonium phosphate fertilizer
("DAP") at its facility in Pascagoula, Mississippi.  In fiscal 1995, the Company
sold approximately 713,000 tons of DAP, which is the most widely used phosphate
fertilizer.  Sales of DAP by the Company in fiscal 1995 were $117.5 million,
which represented approximately 30% of net sales.  In fiscal 1995, approximately
two-thirds of the Company's DAP production was sold into international markets,
primarily to customers in India, China and Mexico.  Phosphate rock, the primary
raw material for the production of phosphate 
<PAGE>
 
fertilizer, is provided under a long-term contract, expiring in 2003, with
Office Cherifien des Phosphates ("OCP"), the national phosphate company of
Morocco, which is the world's largest producer of phosphate rock. The contract
price for phosphate rock with OCP is based on phosphate rock costs incurred by
certain domestic competitors of the Company and on the long-term financial
performance of the Company's phosphate operations. Under this formula, the
Company realizes favorable phosphate rock prices and is afforded significant
protection during periods when market conditions are depressed. Conversely, in
favorable markets, the contract price of phosphate rock will escalate based on
the profitability of the Company's DAP operations. The continued viability and
competitiveness of the Company's phosphate operations are dependent on this
strategic alliance with OCP.

     Potash Fertilizer.  The Company produces potash fertilizer at its facility
located near Carlsbad, New Mexico.  In fiscal 1995, the Company sold
approximately 357,000 tons of granular 60% K2O muriate of potash.  Sales of
potash fertilizer by the Company in fiscal 1995 were $27.4 million, which
represented approximately 7% of net sales.  In May 1994, the Company completed
an expansion of its Carlsbad facility, which has increased granular potash
production capacity from approximately 300,000 tons to approximately 420,000
tons per year.  The Company controls the single largest reserve of potash in the
U.S., with an estimated remaining life, at current production rates, in excess
of 100 years.

     Business Strategy.  The Company's products are global commodities which are
available from multiple sources; therefore, the Company competes primarily on
the basis of price.  As a result, the Company stresses low cost and high
efficiency in every aspect of its operations.  Unlike many of its competitors,
the Company maintains a large and experienced field sales force strategically
located throughout its trade area.  Through its sales force, the Company
provides extensive, cost-effective services to its customers to differentiate
its products, enhance competitiveness and establish the Company as a preferred
supplier.  The Company's marketing efforts are focused on geographically
proximate markets where lower transportation and distribution costs increase
"net backs" (sales less distribution and delivery expenses) and result in
improved margins.  The Company continuously monitors opportunities to expand its
operations through capacity additions, acquisitions, joint ventures and
strategic alliances in the fertilizer business.

     The Company was incorporated in Mississippi in 1994 and is the successor by
merger, effective July 1, 1994, to a business which was formed in 1948 as the
first fertilizer cooperative in the United States.  In August 1994, the Company
completed an initial public offering of 5,800,000 shares of Common Stock, of
which 3,397,928 shares were sold by the Company.  As used herein, the term
"Company" means Mississippi Chemical Corporation and its subsidiaries.  The
principal executive offices of the Company are located at Highway 49 East, Yazoo
City, Mississippi 39194, telephone (601) 746-4131.

                     CURRENT FERTILIZER INDUSTRY CONDITIONS

  The Company is currently benefiting from favorable fertilizer industry
conditions.  In recent years, industry consolidations have eliminated the excess
domestic nitrogen capacity which persisted through the 1980s and early 1990s,
and the construction of new nitrogen production facilities is limited by
substantial construction lead time, capital demands and environmental
regulations.  Developments outside the U.S. have also significantly affected the
nitrogen fertilizer industry.  As a result of recent efforts by several
countries, particularly the former Soviet Union ("FSU") and countries in Eastern
Europe, to convert from centrally planned to market-driven economies, a number
of nitrogen producers in those countries no longer benefit from government-
subsidized natural gas supplies and transportation services.  Consequently, the
prices that those producers charge for delivery to the U.S. market have
increased substantially.  With U.S. corn and wheat stocks at their lowest levels
since 1975 and soybeans at their lowest level since 1989, 
<PAGE>
 
industry experts predict a significant increase in U.S. planted acres in 1996
compared to 1995 and a resultant increase in domestic nitrogen usage. Poor
weather conditions in U.S. growing regions in 1995 limited planting, which also
contributed to the depletion of grain stocks. In addition, as a result of
continued population growth and a shift to higher protein diets, many developing
nations, especially China and India, are increasing their consumption of
nitrogen and other fertilizers. As a result of these and other factors, the
Company and many other U.S. nitrogen fertilizer producers are operating at or
near capacity levels. In addition, current U.S. prices for natural gas are at
relatively low levels, and the prevailing market prices of nitrogen products are
higher than in recent years. Reflecting these favorable fertilizer industry
conditions, the Company's average sales price per ton of nitrogen fertilizer
increased to $138 in fiscal 1995 from $122 in fiscal 1994. See "Risk Factors."

     Recent market fundamentals for phosphate and potash have also been
favorable.  During fiscal 1995, the phosphate fertilizer market reacted
positively to strong demand, principally from China and India, and to declining
exports from the FSU.  Phosphate prices are currently at their highest levels
since the late 1980s. For fiscal 1995, the Company's average sales price of DAP
was $165 per ton as compared to $131 per ton in fiscal 1994.  Potash prices have
remained stable for the past several years.

________________________
(1) Operating income for 1994 reflects a non-cash charge of approximately $6.1
    million relating to the estimated cost of the closure of the gypsum disposal
    facility located at the Company's Pascagoula facility.  Also in 1994, the
    Company's income from continuing operations reflects a charge of
    approximately $1.4 million for reorganization expenses incurred in
    connection with the conversion from a cooperative to a regular business
    corporation.

(2) For 1994, 1993, 1992 and 1991, the Company operated as a cooperative and
    realized deductions for income taxes for amounts paid in cash as patronage
    refunds to its shareholder-members.  If the conversion from a cooperative to
    a regular business corporation had occurred as of July 1, 1990, income taxes
    would have been increased by the following approximate amounts:  $5.5
    million, $5.1 million, $8.5 million and $14.0 million for fiscal 1994, 1993,
    1992 and 1991, respectively.

(3) For 1994, 1993, 1992 and 1991, earnings per share are based on income from
    continuing operations and reflect the reorganization of the Company from a
    cooperative to a regular business corporation as if it had occurred July 1,
    1990.

                                  RISK FACTORS

     In addition to the other information set forth or incorporated by reference
in this Prospectus, the following factors should be considered carefully in
evaluating the Company and its business before purchasing any shares of Common
Stock offered hereby.

     Factors Affecting Fertilizer Demand and Prices.  With virtually all of its
nitrogen fertilizer net sales and approximately 78% of its total net sales in
fiscal 1995 derived from domestic markets, the Company's operating results are
highly dependent upon conditions in the U.S. agricultural industry.  A variety
of factors beyond the Company's control can materially affect domestic
fertilizer demand and pricing.  These factors include U.S. planted acreage,
government agricultural policies (including subsidy and acreage set-aside
programs), projected grain stocks, crop failure, weather and changes in
agricultural production methods.

     International market conditions also significantly influence the Company's
business.  The market for fertilizers is influenced by such factors as the
relative value of the U.S. dollar and its impact upon the cost of importing
fertilizers, foreign agricultural policies, the existence of, or changes in,
import or foreign currency exchange barriers in certain foreign markets, changes
in the hard currency demands of certain countries, such as the FSU, and other
regulatory policies of foreign governments, as well as the laws and policies of
the U.S. affecting foreign trade and investment.  The Company is also subject to
the risks of doing business abroad, including risks associated with economic or
political instability, risks associated with the value of the U.S. dollar and
potential import restrictions or quotas.

     In the past, fertilizer prices have been extremely volatile, with
significant price changes from one growing season to the next.  Current product
prices reflect that world supply and demand for fertilizers are currently in a
more favorable balance than in certain prior years.  However, fertilizers are
global commodities and can be subject to intense price competition from domestic
and foreign sources.  Between 1987 and 1993, phosphate fertilizer prices
declined to their lowest levels since 1977 as a result of an acute supply
surplus.  No assurance can be given, however, that average realized prices paid
for the Company's fertilizer products will continue at current levels.

     Seasonality.  The usage of fertilizer is highly seasonal, and the Company's
quarterly results reflect the fact that, in the Company's markets, significantly
more fertilizer is purchased in the spring.  Significant portions of the
Company's net sales and operating income are generated in the last four months
of the Company's fiscal year (March through June).  Since interim period
operating results reflect the seasonal nature of the Company's business, they
are not indicative of results expected for the full fiscal year.  In addition,
quarterly results can vary significantly from one year to the next due primarily
to weather-related shifts in planting schedules and purchase patterns.  The
Company incurs substantial expenditures for fixed costs throughout the year and
substantial expenditures for inventory in advance of the spring planting season.

     Dependence on Natural Gas.  Natural gas is the primary raw material used in
the manufacture of nitrogen fertilizer products.  Natural gas is used as both a
chemical feedstock and a fuel to produce anhydrous ammonia, which is then used
in the production of all other nitrogen fertilizers.  Anhydrous ammonia is also
a raw material in the production of DAP.  Accordingly, the Company's
profitability is dependent upon the price and availability of natural gas.  A
significant increase in the price of natural gas that is not recovered through
an increase in the price of the Company's fertilizer products, or an extended
interruption in the supply of natural gas to the Company's production
facilities, could have a material 
<PAGE>
 
adverse effect on the Company's results of operations and financial condition.
In recent years, natural gas prices have become increasingly subject to seasonal
volatility.

     Environmental Regulations.  The Company is subject to various environmental
laws and regulations of U.S. federal, state and local governments.  Significant
capital expenditures and operating costs have been incurred and will continue to
be incurred as a result of these laws and regulations.  The Company cannot
predict or quantify the impact of new or changed laws or regulations.  In the
normal course of business, the Company is exposed to risks such as possible
release of hazardous substances into the environment.  Such releases could cause
substantial damage or injuries.

     Competition.  Fertilizer products are global commodities and customers base
their purchasing decisions principally on the delivered price of the product.
As a result, markets for the Company's products are highly competitive.  A
number of U.S. producers compete with the Company in domestic and export
markets, and producers in other countries, including state-owned and government-
subsidized entities, compete with the Company in the U.S. and in foreign markets
to which the Company exports.  Many of the Company's competitors are
significantly larger and have greater financial resources than the Company.

                PRICE RANGE OF COMMON STOCK AND DIVIDEND POLICY

     The Common Stock began trading on the Nasdaq National Market on August 18,
1994, under the symbol "MISS."  The following table sets forth, for the periods
indicated, the high and low sale prices per share of the Common Stock as
reported on the Nasdaq National Market and dividends paid per share of Common
Stock.

</TABLE>

     On November 20, 1995, the last reported sale price of the Common Stock was
$24.00.  At November 17, 1995, the Common Stock was held by approximately 11,385
holders of record.

     The Company anticipates that it will continue to pay regular quarterly
dividends.  However, the amount and timing of the payment of any dividends will
be based on a number of factors, including the future earnings and capital
requirements of the Company, the financial condition of the Company, the
dividend policies of similar publicly traded companies and other factors the
Board of Directors considers relevant.  There can be no assurance that dividends
will be paid in any minimum amounts or at any particular times.  In the future,
it is possible that agreements with lenders may restrict or prohibit the
Company's ability to pay dividends and/or limit the amount of dividends that may
be paid.

     The Selling Shareholder is a cooperative organization which is a supplier
of fertilizer and other farm supply products.  During fiscal 1995, 1994 and
1993, sales of product by the Company to the Selling Shareholder were
approximately $32.3 million, $33.5 million and $33.0 million, respectively,
representing approximately 8.3%, 10.8% and 11.4%, respectively, of the Company's
net sales and approximately 7.3%, 8.7% and 8.6%, respectively, of the Selling
Shareholder's consolidated gross revenues.  Sales of product to the Selling
Shareholder are made in the ordinary course of business at prices and terms
which are determined based on prevailing competitive conditions and which are no
less favorable to the Company than the prices and terms of transactions with
other customers.  During fiscal 1995, the Selling Shareholder bought the
Company's storage facility located in North Little Rock, Arkansas, for
approximately $600,000.  In the opinion of the Company, the sale was on terms as
favorable to the Company as if transacted with an unaffiliated third party.
Robert P. Dixon, a director of the Company, is an executive officer of the
Selling Shareholder.

     On May 23, 1995, the Company's Board of Directors authorized the repurchase
of up to 1.5 million shares of Common Stock.  Pursuant to this authorization, on
July 27, 1995, the Company purchased 200,000 shares at $20.00 per share from the
Selling Shareholder.  The last reported sale price of the Common Stock on Nasdaq
National Market on July 27, 1995, was $22.50.

                                  UNDERWRITING

     Subject to the terms and conditions of the Underwriting Agreement, Schroder
Wertheim & Co. Incorporated (the "Underwriter") has agreed to purchase from the
Selling Shareholder 1,000,000 shares of Common Stock at the public offering
price less the underwriting discounts and commissions set forth on the cover
page of this Prospectus.

     The Underwriting Agreement provides that the obligations of the Underwriter
are subject to certain conditions precedent and that the Underwriter will
purchase all shares of Common Stock offered hereby if any of such shares are
purchased.

     The Underwriter has advised the Selling Shareholder and the Company that it
proposes to offer the shares of Common Stock to the public initially at the
public offering price set forth on the cover page of this Prospectus; that it
proposes initially to allow a concession not in excess of $       per share to
certain dealers; that the Underwriter and such dealers may allow a discount not
in excess of $       per share to 
<PAGE>
 
other dealers; and that the public offering price and the concession and
discount may be changed by the Underwriter after the commencement of the public
offering.

     The Selling Shareholder has granted the Underwriter an option, expiring at
the close of business on the 30th day after the date of the Underwriting
Agreement, to purchase up to an additional 100,000 shares of Common Stock, at
the public offering price less the underwriting discounts and commissions, all
as set forth on the cover page of this Prospectus.  The Underwriter may exercise
such option only to cover over-allotments, if any, in the sale of shares of
Common Stock in the offering.

     The Company and the Selling Shareholder have agreed to indemnify the
Underwriter against certain liabilities, including liabilities under the
Securities Act of 1933, as amended.

     The Selling Shareholder has agreed not to offer, sell or otherwise dispose
of any shares of Common Stock for a period of 90 days from the date of this
Prospectus without the prior written consent of the Underwriter.

     In connection with this offering, the Underwriter may have engaged in
passive market-making transactions in the Common Stock on the Nasdaq National
Market in accordance with Rule 10b-6A under the Securities Exchange Act of 1934,
as amended, during the two business day period before commencement of offers or
sales of the Common Stock.  Passive market-making transactions must comply with
applicable volume and price limits and be identified as such.  In general, a
passive market maker may display its bid at a price not in excess of the highest
independent bid for the security; if all independent bids are lowered below the
passive market maker's bid, however, such bid must then be lowered when certain
purchase limits are exceeded.

                                 LEGAL MATTERS

     Certain legal matters with respect to the shares of Common Stock offered
hereby will be passed upon for the Company by Hughes & Luce, L.L.P., Dallas,

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Under Mississippi law, a corporation may indemnify any person who was or is
a party to an action (other than an action by or in the right of the
corporation) by reason of his service as a director or officer of the
corporation, or his service, at the corporation's request, as a director,
officer, employee or agent of another corporation or other enterprise, against
expenses (including attorneys' fees) that are actually and reasonably incurred
by him ("Expenses"), and judgments, fines and amounts paid in settlement that
are actually and reasonably incurred by him, in connection with the defense or
settlement of such action, provided that he acted in good faith and in a manner
he reasonably believed to be in or not opposed to the corporation's best
interest and, with respect to any criminal action or proceeding, had no
reasonable cause to believe that his conduct was unlawful.  Mississippi law
permits a corporation to indemnify any person referred to above against
reasonable expenses incurred in connection with the defense or settlement of an
action by or in the right of the corporation, provided that he has not been
judged liable to the corporation.  The determination as to whether a person
seeking indemnification has met the required standard of conduct is to be made
(i) by a majority vote of a quorum of disinterested members of the board of
directors and if a quorum of disinterested directors cannot be obtained, by vote
of a majority of the members of a committee (the "Committee") composed of at
least two disinterested directors and designated by the entire Board, or (ii) by
independent legal counsel if the disinterested directors or the Committee so
direct, or (iii) by the shareholders, provided that shares owned or controlled
by interested directors do not count.  Mississippi law also provides for the
mandatory indemnification of any director, officer, employee or agent against
Expenses to the extent such person has been successful in any proceeding.

     The Company's Articles of Incorporation provide for indemnification of the
Company's directors to the fullest extent permitted by Mississippi law.

     The Company maintains liability insurance for the benefit of its directors
and officers.

     Under the terms of the Underwriting Agreement, the Underwriter has agreed
to indemnify, under certain conditions, the Company, its directors, certain of
its officers and persons who control the Company within the meaning of the
Securities Act of 1933, as amended, against certain liabilities.

ITEM 16.  EXHIBITS.

     The information required by this Item 16 is contained in a separate Index
to Exhibits set forth beginning on page II-5 of this registration  statement.

ITEM 17.  UNDERTAKINGS.

     (b) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 that is incorporated by reference in the
registration  statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

     (h) Insofar as indemnification by the registrant for liabilities arising
under the Securities Act of 1933 may be permitted to directors, officers and
controlling persons of the registrant pursuant to the foregoing provisions, or
otherwise, the registrant has been advised that in the opinion of the Securities
and Exchange Commission, such indemnification is against public policy as
expressed in the Act and is, therefore, unenforceable.  In the event that a
claim for indemnification against such liabilities (other than the payment by
the registrant of expenses incurred or paid by a director, officer or
controlling person of the registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.

     (i) The undersigned registrant hereby undertakes that:

          (1) For purposes of determining any liability under the Securities Act
     of 1933, the information omitted from the form of prospectus filed as part
     of this Registration Statement in reliance upon Rule 430A and contained in
     a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or
     (4) or 497(h) under the Securities Act shall be deemed to be part of this
     Registration Statement as of the time it was declared effective.

          (2) For the purpose of determining any liability under the Securities
     Act of 1933, each post-effective amendment that contains a form of
     prospectus shall be deemed to be a new registration statement relating to
     the securities offered therein, and the offering of such securities at that
     time shall be deemed to be the initial bona fide offering thereof.

accounting requirements of the Act and the published rules and regulations
thereunder;

  (iii) On the basis of specified procedures as of a specified date not more
than five days prior to the date of their letter (which procedures do not
constitute an examination made in accordance with generally accepted auditing
standards), consisting of a reading of the latest available unaudited interim
financial statements of the Company and its subsidiaries (with an indication of
the date or dates of each such latest available financial statements), a reading
of the latest available minutes of any meeting of the Board of Directors and
stockholders of the Company and its subsidiaries since June 30, 1995, inquiries
of officials of the Company who have responsibility for financial and accounting
matters subsequent to June 30, 1995, respectively, and such other procedures or
inquiries as are specified in such letter, nothing came to their attention that
caused them to believe that:

     (A) the information relating to the Company and its subsidiaries for the
fiscal years ended June 30, 1991, 1992, 1993, 1994 and 1995, and any unaudited
information relating to the Company, included in the Prospectus under the
caption "Summary Financial Data" does not agree with corresponding amounts in
the audited consolidated balance sheets and the audited consolidated statements
of income and the audited statements of cash flows as of and for the periods
then ended;

     (B) Any unaudited consolidated balance sheets, any unaudited consolidated
statements of operations, any unaudited consolidated statements of shareholders'
equity, and any unaudited consolidated statements of cash flow, included or
incorporated by reference in the Prospectus do not comply as to form in all
material respects with the applicable accounting requirements of the Act and the
published rules and regulations thereunder, or were not prepared on a basis
substantially consistent with that of the audited financial statements for the
year ended June 30, 1995, included or incorporated by reference in the
Prospectus;

     (C) as of a specified date not more than five days prior to the date of
their letter, there was any change in the long-term debt or short-term debt of
the Company and its subsidiaries on a consolidated basis, or any decreases in
shareholders' equity, inventory, working capital or total assets of the Company,
as compared with the amounts shown in the consolidated balance sheets as of
September 30, 1995, included or incorporated by reference in the Prospectus,
except in each case for changes which the Prospectus discloses have occurred or
may occur or which are described in their letter;

     (D) for the period from September 30, 1995, to a specified date not more
than five days prior to the date of such letter, there was any decrease, as
compared with the corresponding period of the preceding fiscal year, in the
following consolidated amounts: net sales, operating income, income from
continuing operations before income taxes and cumulative effect of change in

                                      -17-
<PAGE>
 
accounting principle, net income, and earnings per share of the Company and its
subsidiaries, except in all instances for decreases which the Registration
Statement discloses have occurred or may occur; or if there was any decrease,
setting forth the amount of such decrease; or if the Company and its
subsidiaries have no financial statements for any period subsequent to September
30, 1995, and other sufficient information is not available to management in
order to enable management to comment on net sales, operating income, income
from continuing operations before income taxes and cumulative effect of change
in accounting principle, net income and earnings per share of the Company and
its subsidiaries subsequent to September 30, 1995, stating that management
believes that there was no decrease in net sales, operating income, income from
continuing operations before income taxes and cumulative effect of change in
accounting principle,  net income and earnings per share of the Company and its
subsidiaries for the period subsequent to September 30, 1995, as compared with
the corresponding period of the preceding fiscal year; and

  (iv) in addition to the examination referred to in their reports included in
the Registration Statement and the Prospectus and the limited procedures
referred to in clause (iii) above, they have carried out certain specified
procedures, not constituting an audit, with respect to certain amounts,
percentages and financial information which are derived from the general
accounting records of the Company and its subsidiaries which appear in (a) the
Prospectus under the captions "Prospectus Summary," "Risk Factors," "Price Range
of Common Stock and Dividends" and "Selling Shareholder, (b) the Company's
Annual Report on Form 10-K (the "Form 10-K") for the fiscal year ended June 30,
1995, (c) the Company's Proxy Statement for its Annual Meeting of Stockholders
held on November 14, 1995, incorporated by reference in such Form 10-K, (d)
pages 1   and 20 through 41 of the Company's Annual Report to Stockholders for
the fiscal year ended June 30, 1995, incorporated by reference in such Form 10-
K, and (e) the Company's Quarterly Report on Form 10-Q for the quarter ended
September 30, 1995 under Items 1 and 2 of Part I, each of which is specified by
you, and have compared such amounts and financial information with the
accounting records of the Company and its subsidiaries and have found them to be
in agreement and have proved the mathematical accuracy of certain specified
percentages;


  (h) (i) Neither the Company nor any of its subsidiaries shall have sustained
since June 30, 1995, any loss or interference with its business from fire,
explosion, flood or other calamity, whether or not covered by insurance, or from
any labor dispute or court or governmental action, order or decree; and (ii)
since the respective dates as of which information is given in the Prospectus,
there shall not have been any change in the capital stock or short-term debt or
long-term debt of the Company or any of its subsidiaries nor any change or any
development involving a prospective change, in or affecting the general affairs,
management, financial position, shareholders'equity or results of operations of
the Company or any of its subsidiaries, otherwise than as set forth or
contemplated in the Prospectus, the effect of which, in any such case described
in clause (i) or (ii), is in your judgment so material and adverse as to make it
impracticable or inadvisable to proceed with the public offering or the delivery
of the Securities on the terms and in the manner contemplated in the Prospectus;

  (i) Between the date hereof and the Time of Delivery there shall have been no
declaration of war by the Government of the United States; at the Time of
Delivery there shall not have occurred any material adverse change in the
financial or securities markets in the United States or in political, financial
or economic conditions in the United States or any outbreak or material
escalation of hostilities or other calamity or crisis, the effect of which is
such as to make it, in the judgment of theUnderwriter, impracticable to market
the Securities or to enforce contracts for the resale of Securities and no event
shall have occurred resulting in (i) trading in securities generally 

                                      -18-
<PAGE>
 
on the New York Stock Exchange or the Nasdaq National Market being suspended or
limited or minimum or maximum prices being generally established on the Nasdaq
National Market or on such exchange, or additional material governmental
restrictions, not in force on the date of this Agreement, being imposed upon
trading in securities generally by the Nasdaq National Market or such exchange
or by order of the Commission or any court or other governmental authority or
(ii) a general banking moratorium being declared by either Federal or New York
authorities;

  (j) The Company and the Selling Securityholder shall have furnished or caused
to be furnished to you at the Time of Delivery certificates signed by the Chief
Executive Officer and the Chief Financial Officer, on behalf of the Company, and
the Selling Securityholder or the Selling Securityholder Attorneys, on behalf of
the Selling Securityholder, satisfactory to you as to such matters as you may

hereunder to be performed at or prior to the Time of Delivery; the Company shall

the statements contained or incorporated by reference in the Registration
Statement and the Prospectus were true and correct and neither the Registration
Statement nor the Prospectus omitted to state a material fact required to be
stated therein or necessary to make the statements therein not misleading and
(b) since the Effective Date, no event has occurred that is required by the Act
or the rules and regulations of the Commission thereunder to be set forth in an
amendment of, or a supplement to, the Prospectus that has not been set forth in

(a) of this Section 7; and

  8. (a) The Company and the Selling Securityholder, jointly and severally, will
indemnify and hold harmless the Underwriter against any losses, claims, damages
or liabilities, joint or several, to which the Underwriter may become subject,
under the Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon (i)
any untrue statement or alleged untrue statement made by the Company in Section
1A of this Agreement, (ii) any untrue statement or alleged untrue statement of a
material fact contained or incorporated by reference in any Preliminary
Prospectus, the Registration Statement or the Prospectus, or any amendment or
supplement thereto, or in any Blue Sky application or other document executed by
the Company specifically for that purpose or based upon written information
furnished by the Company filed in any state or other jurisdiction in order to
qualify any or all of the Securities under the securities laws thereof or filed
with the Commission or any securities association or securities exchange (each,
an "Application"), or the omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
made or incorporated by reference therein not misleading, or (iii) the
employment by the Company of any device, scheme or artifice to defraud, or the
engaging by the Company in any act, practice or course of business which
operates or would operate as a fraud or deceit, or any conspiracy with respect
thereto, in which the Company shall participate, in connection with the issuance
and sale of any of the Securities, and will reimburse the Underwriter for any
legal or other expenses reasonably incurred by the Underwriter in connection
with investigating, preparing to defend, defending or appearing as a third-party
witness in connection with any such action or claim; provided, however, that the
Company and the Selling Securityholder shall not be liable in any such 

                                      -19-
<PAGE>
 
case to the extent that any such loss, claim, damage or liability arises out of
or is based upon an untrue statement or alleged untrue statement or omission or
alleged omission relating to the Underwriter made in any Preliminary Prospectus,
the Registration Statement, the Prospectus or such amendment or supplement or
any Application in reliance upon and in conformity with written information
furnished to the Company by the Underwriter through you expressly for use
therein; provided, further, that the indemnity agreement contained in this
Section 8(a) with respect to any Preliminary Prospectus shall not inure to the
benefit of the Underwriter (or any persons controlling the Underwriter) on
account of any losses, claims, damages, liabilities or litigation arising from
the sale of Securities to any person, if the Underwriter fails to send or give a
copy of the Prospectus, as the same may be then supplemented or amended, to such
person, within the time required by the Act and the untrue statement or alleged
untrue statement or omission or alleged omission of a material fact contained in
such Preliminary Prospectus was corrected in the Prospectus, unless such failure
is the result of noncompliance by the Company with Section 5(c) hereof. (b) The
Selling Securityholder will indemnify and hold harmless the Underwriter and the
Company against any losses, claims, damages or liabilities to which the
Underwriter or the Company may become subject under the Act or otherwise,
insofar as such losses, claims, damages or liabilities (or actions in respect
thereof) arise out of or are based upon (i) any untrue statement or alleged
untrue statement made by the Selling Securityholder in Section 1B of this
Agreement, or (ii) any untrue statement or alleged untrue statement of a
material fact contained in the Preliminary Prospectus, the Registration
Statement, or the Prospectus, or any amendment or supplement thereto, or the
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading, in
each case to the extent, but only to the extent, that such untrue statement or
alleged untrue statement or omission or alleged omission was made in the
Preliminary Prospectus, the Registration Statement, the Prospectus or such
amendment or supplement in reliance upon and in conformity with written
information furnished to the Underwriter or the Company by the Selling
Securityholder expressly for use therein, and will reimburse the Underwriter or
the Company for any legal or other expenses reasonably incurred by the
Underwriter, the Company in connection with investigating, preparing to defend,
defending or appearing as a third-party witness in connection with any such
action or claim; provided, however, that the indemnity agreement contained in
this Section 8(b) with respect to any Preliminary Prospectus shall not inure to
the benefit of the Underwriter (or any persons controlling the Underwriter) on
account of any losses, claims, damages, liabilities or litigation arising from
the sale of Securities to any person, if the Underwriter fails to send or give a
copy of the Prospectus, as the same may be then supplemented or amended, to such
person, within the time required by the Act and the untrue statement or alleged
untrue statement or omission or alleged omission of a material fact contained in
such Preliminary Prospectus was corrected in the Prospectus, unless such failure
is the result of noncompliance by the Company with Section 5(c) hereof.

  (c) In addition to any obligations of the Company and the Selling
Securityholder under Section 8(a) and 8(b), the Company and the Selling
Securityholder agree that they shall perform their indemnification obligations
under Section 8(a) and Section 8(b) (as modified by the last paragraph of this
Section 8(c)) with respect to counsel fees and expenses and other expenses
reasonably incurred by making payments within 45 days to the Underwriter in the
amount of the statements of the Underwriter's counsel or other statements which
shall be forwarded by the Underwriter, and that it shall make such payments
notwithstanding the absence of a judicial determination as to the propriety and
enforceability of the obligation to reimburse the Underwriter for such expenses
and the possibility that such payments might later be held to have been improper
by a court until such time as a court orders return of such payments.

                                      -20-
<PAGE>
 
  The indemnity agreement in Section 8(a) and Section 8(b) shall be in addition
to any liability which the Company or the Selling Securityholder may otherwise
have and shall extend upon the same terms and conditions to each person, if any,
who controls the Underwriter within the meaning of the Act or the Exchange Act.

  In no event shall the Selling Securityholder be required pursuant to the
indemnity agreement under Section 8(a) and 8(b) to pay a total amount in excess
of the net amount received by the Selling Securityholder hereunder for the sale
of Securities to the Underwriter.

  (d) The Underwriter will indemnify and hold harmless the Company and the
Selling Securityholder against any losses, claims, damages or liabilities to
which the Company or the Selling Securityholder may become subject, under the
Act or otherwise, insofar as such losses, claims, damages or liabilities (or
actions in respect thereof) arise out of or are based upon an untrue statement
or alleged untrue statement of a material fact contained in any Preliminary
Prospectus, the Registration Statement or the Prospectus, or any amendment or
supplement thereto, or any Application, or arise out of or are based upon the
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading, in
each case to the extent, but only to the extent, that such untrue statement or
alleged untrue statement or omission or alleged omission was made in any
Preliminary Prospectus, the Registration Statement, the Prospectus or such
amendment or supplement or any Application in reliance upon and in conformity
with written information furnished to the Company or the Selling Securityholder
by the Underwriter relating to the Underwriter expressly for use therein, and
will reimburse the Company or the Selling Securityholder for any legal or other
expenses reasonably incurred by the Company or the Selling Securityholder in
connection with investigating or defending any such action or claim.

  The indemnity agreement in this Section 8(d) shall be in addition to any
liability which the Underwriter may otherwise have and shall extend, upon the
same terms and conditions, to each officer and director of the Company or of the
Selling Securityholder and to each person, if any, who controls the Company or
the Selling Securityholder within the meaning of the Act or the Exchange Act.

  (e) Promptly after receipt by an indemnified party under Section 8(a), 8(b) or
8(d) of notice of the commencement of any action (including any governmental
investigation), such indemnified party shall, if a claim in respect thereof is
to be made against the indemnifying party under such subsection, notify the
indemnifying party in writing of the commencement thereof; but the omission so
to notify the indemnifying party shall not relieve it from any liability which
it may have to any indemnified party under Section 8(a), 8(b) or 8(d) except to
the extent it was unaware of such action and has been prejudiced in any material
respect by such failure or from any liability which it may have to any
indemnified party otherwise than under such Section 8(a), 8(b) or 8(d). In case
any such action shall be brought against any indemnified party and it shall
notify the indemnifying party of the commencement thereof, the indemnifying
party shall be entitled to participate therein and, to the extent that it shall
wish, jointly with any other indemnifying party similarly notified, to assume
the defense thereof, with counsel satisfactory to such indemnified party, and
after notice from the indemnifying party to such indemnified party of its
election so to assume the defense thereof, the indemnifying party shall not be
liable to such indemnified party under such subsection for any legal or other
expenses subsequently incurred by such indemnified party in connection with the
defense thereof other than reasonable costs of investigation. If, however, (i)
the indemnifying party has authorized the employment of counsel for the
indemnified party at the expense of the indemnifying party or (ii) an
indemnified party shall have reasonably concluded that representation of such

                                      -21-
<PAGE>
 
indemnified party and the indemnifying party by the same counsel would be
inappropriate under applicable standards of professional conduct due to actual
or potential differing interests between them and the indemnified party so
notifies the indemnifying party, then the indemnified party shall be entitled to
employ counsel different from counsel for the indemnifying party at the expense
of the indemnifying party and the indemnifying party shall not have the right to
assume the defense of such indemnified party. In no event shall the indemnifying
parties be liable for fees and expenses of more than one counsel (in addition to
local counsel) for all indemnified parties in connection with any one action or
separate but similar or related actions in the same jurisdiction arising out of
the same set of allegations or circumstances. The counsel with respect to which
fees and expenses shall be so reimbursed shall be designated in writing by the
Underwriter in the case of parties indemnified pursuant to Section 8(a) and
Section 8(b) and by the Company in the case of parties indemnified pursuant to
Section 8(d).

  No indemnifying party shall, without the prior written consent of the
indemnified party, effect any settlement of any pending or threatened proceeding
in respect of which any indemnified party is or could have been a party and
indemnity could have been sought hereunder by such indemnified party, unless
such settlement includes an unconditional release of such indemnified party from
all liability on claims that are the subject matter of such proceeding.

  (f) In order to provide for just and equitable contribution under the Act in
any case in which (i) the Underwriter (or any person who controls the
Underwriter within the meaning of the Act or the Exchange Act) makes claim for
indemnification pursuant to Section 8(a) or Section 8(b) hereof, but is
judicially determined (by the entry of a final judgment or decree by a court of
competent jurisdiction and the expiration of time to appeal or the denial of the
last right of appeal) that such indemnification may not be enforced in such case
notwithstanding the fact that Section 8(a) or Section 8(b) provides for
indemnification in such case or (ii) contribution under the Act may be required
on the part of the Underwriter or any such controlling person in circumstances
for which indemnification is provided under Section 8(d), then, and in each such
case, the Company, the Selling Securityholder and the Underwriter shall
contribute to the aggregate losses, claims, damages or liabilities to which they
may be subject as an indemnifying party hereunder (after contribution from
others) in such proportion so that the Underwriter is responsible for the
portion represented by the percentage that the underwriting discount appearing
on the cover page of the Prospectus bears to the public offering price appearing
thereon and the Selling Securityholder and the Company shall be jointly and
severally responsible for the portion represented by the percentage that the
total net proceeds of the offering received by the Selling Securityholder bears
to the total public offering price appearing on the cover page of the
Prospectus; provided, however, that, in any such case, (x) the Underwriter shall
not be required to contribute any amount in excess of the underwriting discount
applicable to the Securities purchased by the Underwriter, (y) the Selling
Securityholder shall not in any case be required to contribute an amount in
excess of the proceeds of the offering received by such Selling Securityholder,
and (z) no person guilty of a fraudulent misrepresentation (within the meaning
of Section 11(f) of the Act) shall be entitled to a contribution from any person
who was not guilty of such fraudulent misrepresentation. The amount paid or
payable by the Underwriter as result of this Section 8(f) shall be deemed to
include any legal or other expenses reasonably incurred by the Underwriter in
connection with investigating, preparing to defend or defending any such claim.

  (g) Promptly after receipt by any party to this Agreement of notice of the
commencement of any action, suit or proceeding, such party will, if a claim for
contribution in respect thereof is to be made against another party (the
"contributing party"), notify the contributing party of the commencement
thereof; but the omission so to notify the contributing party will not relieve
it from any liability 

                                      -22-
<PAGE>
 
which it may have to any other party for contribution under the Act except to
the extent it was unaware of such action and has been prejudiced in any material
respect by such failure or from any liability which it may have to any other
party other than for contribution under the Act. In case any such action, suit
or proceeding is brought against any party, and such party notifies a
contributing party of the commencement thereof, the contributing party will be
entitled to participate therein with the notifying party and any other
contributing party similarly notified.

  9. The respective indemnities, agreements, representations, warranties and
other statements of the Company, the Selling Securityholder and the Underwriter,
as set forth in this Agreement or made by or on behalf of them, respectively,
pursuant to this Agreement, shall remain in full force and effect, regardless of
any investigation (or any statement as to the results thereof) made by or on
behalf of the Underwriter or any controlling person of the Underwriter, or the
Company, or an officer or director or controlling person of the Company or the
Selling Securityholder, and shall survive delivery of and payment for the
Securities.

  10. This Agreement shall become effective (a) if the Registration Statement
has not heretofore become effective, at the earlier of 12:00 Noon, New York City
time, on the first full business day after the Registration Statement becomes
effective, or at such time after the Registration Statement becomes effective as
you may authorize the sale of the Securities to the public by the Underwriter or
other securities dealers, or (b) if the Registration Statement has heretofore
become effective, at the earlier of 24 hours after the filing of the Prospectus
with the Commission or at such time as you may authorize the sale of the
Securities to the public, unless, prior to any such time you shall have received
notice from the Selling Securityholder that it elects that this Agreement shall
not become effective, or you,  shall have given notice to the Company and the
Selling Securityholder that you elect that this Agreement shall not become
effective; provided, however, that the provisions of this Section 10 and Section
6 and Section 8 hereof shall at all times be effective.

  If this Agreement, by election of the Underwriter, shall not become effective
pursuant to the provisions of this Section, the Company and the Selling
Securityholder shall not then be under any liability to the Underwriter except
as provided in Section 6 and Section 8 hereof, but if this Agreement becomes
effective and is not so terminated but the Securities are not delivered by or on
behalf of the Selling Securityholder as provided herein because the Company or
the Selling Securityholder has been unable for any reason beyond its control and
not due to any default by it to comply with the terms and conditions hereof, the
Company will reimburse the Underwriter, for all out-of-pocket expenses approved
in writing by the Underwriter, including fees and disbursements of counsel,
reasonably incurred by the Underwriter in making preparations for the purchase,
sale and delivery of the Securities, but the Company and the Selling
Securityholder shall then be under no further liability to the Underwriter
except as provided in Section 6 and Section 8 hereof.

  11. All statements, requests, notices and agreements hereunder shall be in
writing or by written telecommunication, and shall be sufficient in all respects
if delivered or sent by registered mail, if to the Underwriter in care of
Schroder Wertheim & Co. Incorporated at 787 Seventh Avenue, New York, New York
10019, Attention: Syndicate Department; and if to the Company or the Selling
Securityholder, to Mississippi Chemical Corporation, Post Office Box 388, Yazoo
City, MS 39194-0388, Attention: Charles O. Dunn, President and Chief Executive
Officer.

  12. This Agreement shall be binding upon, and inure solely to the benefit of,
the Underwriter, the Company and the Selling Securityholder and, to the extent
provided in Section 8 and Section 9 hereof, the officers and directors of the
Company and each person who controls the Company or the Underwriter, and their
respective heirs, executors, administrators, successors and assigns, and no

                                      -23-
<PAGE>
 
other person shall acquire or have any right under or by virtue of this
Agreement. No purchaser of any of the Securities from the Underwriter shall be
deemed a successor or assign by reason merely of such purchase.

  13. Time shall be of the essence of this Agreement.

  14. This Agreement shall be construed in accordance with the laws of the state
of New York.

  15. This Agreement may be executed by any one or more of the parties hereto in
any number of counterparts, each of which shall be deemed to be an original, but
all such counterparts shall together constitute one and the same instrument.

  If the foregoing is in accordance with your understanding, please sign and
return to us a counterpart hereof, and upon the acceptance hereof by you, this
letter and such acceptance hereof shall constitute a binding agreement among
you, the Company and the Selling Securityholder.

                              Very truly yours,

                               November 21, 1995


Mississippi Chemical Corporation
P.O. Box 388
Yazoo City, Mississippi  39194

Ladies and Gentlemen:

     We have acted as counsel to Mississippi Chemical Corporation, a Mississippi
corporation (the "Company"), in connection with the Company's registration under
the Securities Act of 1933, as amended (the "Act"), of 1,000,000 shares of the
Company's common stock, par value $0.01 per share ("Common Stock"), on behalf of
SF Services, Inc. (the "Selling Shareholder"), and the sale by the Selling
Shareholder of up to 100,000 additional shares of Common Stock subject to an
over-allotment option to be granted to the Underwriter, pursuant to a
Registration Statement on Form S-3 (the "Registration Statement") filed with the
Securities and Exchange Commission (the "Commission") (all 1,100,000 of such
shares of Common Stock, the "Shares").

     In connection with this opinion, we have examined such documents and
records of the Company and such statutes, regulations, and other instruments and
certificates as we have deemed necessary or advisable for the purposes of this
opinion.  We have assumed that all signatures on all documents presented to us
are genuine, that all documents submitted to us as originals are accurate and
complete, and that all documents submitted to us as copies are true and correct
copies of the originals thereof.  We have also relied upon such certificates of
public officials, corporate agents, and officers of the Company and the Selling
Shareholder to the extent necessary or advisable with respect to the accuracy of
material factual matters contained therein which were not independently
established.

     Based on the foregoing, we are of the opinion that the Shares being sold by
the Selling Shareholder are validly issued, fully paid, and nonassessable.

     This opinion may be filed as an exhibit to the Registration Statement.
Consent is also given to the reference to this firm as having passed on the
validity of the Shares under the caption "Legal Matters" in the prospectus
contained in the Registration Statement.  In giving this consent, we do not
admit that we are included in the category of persons whose consent is required
under Section 7 of the Act or the rules and regulations of the Commission
promulgated thereunder.

                                      Very truly yours,
